document or agreement contemplated hereby, or (ii) result in a violation or 
breach of, or constitute a default under, or result in the creation of any 
encumbrance upon, or, create any rights of termination, cancellation or 
acceleration with respect to any of the obligations undertaken by the 
Shareholders hereunder. 

          8.   CONSENTS.  No consent, approval or other 

<PAGE>

authorization of any governmental authority or under any contract or other 
agreement or commitment to which the Shareholders are parties or by which its 
or their respective assets are bound is required as a result of or in 
connection with the execution or delivery of this Agreement which the failure 
to obtain would materially adversely affect the performance by the 
Shareholders of their obligations hereunder or under any agreement or 
document contemplated hereby. 

          9.   COMPLIANCE WITH LAWS.  The Shareholders are and have been in 
compliance with all applicable laws, regulations (including federal, state 
and local procurement regulations), orders, judgments and decrees with 
respect to the WRI Stock except where the failure to so comply would not

contemplated hereby. 

          10.  OWNERSHIP.  Each Shareholder owns beneficially and of record

<PAGE>

          11.  NO OTHER REPRESENTATIONS.  Except to the extent set forth in 
this Agreement or expressly incorporated herein, no Shareholder has made any 
representation or warranty whatsoever and hereby disclaims all liability or 
responsibility for any other representation or warranty made, communicated or 
furnished (orally or in writing) to the other party or its representatives 
(including without limitation, any opinion, information, projection or advice 
as may have been or may be provided to WRI or any of its affiliates by any 
partner, director, officer, employee, agent, consultant or representative of 
any Shareholder).

     III.      REPRESENTATIONS OF WRI AND U.S. TIRE ENTITIES

     A.   WRI represents and warrants that all of the following 
representations and warranties in this Section are true and correct at the 
date of this Agreement and shall be true and correct at the time of the 
Closing. 

          1.   DUE ORGANIZATION.  Each of WRI, New U.S. Tire, Tirus and 
Recycling, L.P. is duly organized, validly existing and in good standing 
under the laws of the State in which each is organized, and is duly 
authorized and qualified under all applicable laws, regulations, and 
ordinances of public authorities to carry on its businesses in the places and 
in the manner as now conducted except for where the failure to be so 
authorized or qualified would not have a material adverse effect on its 
business, operations, affairs, properties, assets or 

<PAGE>

condition (financial or otherwise).  

          2.   WRI DELIVERED STOCK.  The WRI Delivered Stock shall constitute 
100% of the valid and legally issued shares of New U.S. Tire and membership 
interests of Tirus and Recycling Partners, L.P. owned by WRI as of the 
Closing Date, fully paid and nonassessable, and shall be conveyed free and 
clear of all Liens created by WRI or by any of the U.S. Tire Entities.  Upon 
delivery of the shares of the WRI Delivered Stock to the Shareholders at the 
Closing, the Shareholders shall have good and marketable title to such 
shares. 

               (a)  WRI received the WRI Delivered Stock in connection with 
the 1996 Reorganization from certain of the Shareholders and their 
affiliates, and there have been no subsequent issuances by U.S. Tire of any 
shares of its capital stock or by Tirus of any membership interests.  Since 
the 1996 Reorganization, there have not been issued any conversion or 
exchange rights, subscriptions, options, warrants or other arrangements or 
commitments obligating the U.S. Tire or Tirus to issue any shares of capital 
stock or other securities or to purchase, redeem or otherwise acquire any 
shares of capital stock or other securities, or to pay any dividend or make 
any distribution in respect thereof.  

               (b)  WRI (i) owns of record and has good and marketable title 
to all of the issued and outstanding shares of the WRI Delivered Stock, free 
and clear of any and all claims, Liens, or encumbrances and (ii) has the 
right to vote the WRI 

<PAGE>

Delivered Stock on any matters as to which any shares of U.S. Tire common 
stock or any Tirus membership interests or Tire Recycling, L.P. partnership 
interests are entitled to be voted under the laws of the state of 
incorporation of such companies and such companies' charter documents, free 
of any right of any other person. 

          3.   PERMITS AND INTANGIBLES.  The representations and warranties 
in this Section 3 are limited to the extent that any Shareholder has actual 
or constructive knowledge that (a) WRI will or is threatened to be in breach 
of any warranty on the Closing Date or (b) any representation contains any 
untrue statement of fact or omits to state a material fact necessary to make 
the statements herein, in light of the circumstances which they are made, not 
misleading.  Since the 1996 Reorganization, U.S. Tire and Tirus have not 
cancelled, terminated or otherwise failed to renew any license, franchise, 
permit and other governmental authorization, including any permit, title 
(including motor vehicle titles and current registrations), fuel permit, 
license, franchise, certificate, trademarks trade name, patent, patent 
application and copyright owned or held by company as of the closing date of 
the 1996 Reorganization, the absence of any of which would have a material 
adverse effect on the business, operations, properties, assets or conditions 
(financial or otherwise) of such companies (the "Material Permits").  WRI has 
not received notice that any governmental authority intends to cancel, 
terminate or not renew any such 

<PAGE>

Material Permit.  Since the 1996 Reorganization, U.S. Tire has conducted and 
is conducting its business in compliance with the requirements, standards, 
criteria and conditions set forth in such Material Permits and is not in 
violation of any of the foregoing except where such noncompliance or 
violation would not have a material adverse effect on the business, 
operations, properties, assets or conditions (financial or otherwise) of the 
company.   

          4.  VALIDITY OF OBLIGATIONS.  The execution and delivery of this 
Agreement, the Tire Lending Note and any other agreements annexed hereto to 
which WRI is a party and the performance of the transactions contemplated 
herein or therein have been duly and validly authorized by the Boards of 
Directors, and this Agreement, the Tire Lending Note, and such other 
agreements have each been duly and validly authorized by all necessary 
corporate action, duly executed and delivered and are the legal, valid and 
binding obligations of each of such entities to the extent that it is a party 
thereto, enforceable against such party thereto in accordance with their 
respective terms subject to the Equitable Exceptions. 

          5.   NO CONFLICTS. The representations and warranties in this 
Section 5 are limited to the extent that any Shareholder has actual or 
constructive knowledge which has not been disclosed to a member of the WRI 
Board, other than a Shareholder, that (a) WRI will or is threatened to be in 
breach of any warranty on the Closing Date or (b) any representation 

<PAGE>

contains any untrue statement of fact or omits to state a material fact 
necessary to make the statements herein, in light of the circumstances which 
they are made, not misleading.  The execution, delivery and performance of 
this Agreement and the other agreements and documents contemplated hereby by 
WRI, New U.S. Tire, Tirus and Recycling, L.P. and the consummation of the 
transactions contemplated hereby will not (i) violate any provision of any of 
the entities' organizational documents, (ii) violate any statute, rule, 
regulation, order or decree of any public body or authority by which such 
entities or its or their respective properties or assets are bound, or (iii) 
result in a violation or breach of, or constitute a default under, or result 
in the creation of any encumbrance upon, or, create any rights of 
termination, cancellation or acceleration in any person with respect to any 
contract or any material license, franchise or permit of WRI, New U.S. Tire, 
Tirus and Recycling, L.P. or any other agreement, contract, indenture, 
mortgage or instrument to which WRI, New U.S. Tire, Tirus and Recycling, L.P. 
is a party or by which any of its properties or assets is bound, the result 
of which would materially adversely affect the WRI's ability to perform its 
obligations hereunder or under any document or agreement contemplated hereby. 

          6.   EXPENSES.  WRI will pay its expenses incurred in connection 
with this Agreement. 

          7.   CONSIDERATION.  To the best of the knowledge of WRI's Board of 
Directors, the fair market value of the U.S. Tire 

<PAGE>

stock, Tirus membership interests and other consideration given by WRI, will 
be approximately equal to the fair market value of consideration received by 
it hereunder. 

          8.   CONSENTS. The representations and warranties in this Section 8 
are limited to the extent that any Shareholder has actual or constructive 
knowledge which has not been disclosed to a member of the WRI Board, other 
than a Shareholder, than (a) WRI will or is threatened to be in breach of any 
warranty on the Closing Date or (b) any representation contains any untrue 
statement of fact or omits to state a material fact necessary to make the 
statements herein, in light of the circumstances which they are made, not 
misleading.  No consent, approval, authorization or order of any court, 
Agency or any other person is required in order to permit WRI to consummate 
the transactions contemplated by this Agreement the absence of which would 
have a materially adverse effect on WRI's ability to perform its obligations 
hereunder. 

          9.   TAX MATTERS. The representations and warranties in this 
Section 9 are limited to the extent that any Shareholder has actual or 
constructive knowledge which has not been disclosed to a member of the WRI 
Board, other than a Shareholder, that (a) WRI will or is threatened to be in 
breach of any warranty on the Closing Date or (b) any representation contains 
any untrue statement of fact or omits to state a material fact necessary to 
make the statements herein, in light of the circumstances which they are 
made, not misleading. 

<PAGE>

               (a)  Since the 1996 Reorganization and except for the 1997 and 
1998 tax years, U.S. Tire and Tirus have filed all income tax returns 
required to be filed by U.S. Tire or Tirus and all returns of other Taxes (as 
defined below) required to be filed and has paid or provided for all Taxes 
shown to be due on such returns.  Since the 1996 Reorganization (i) no action 
or proceeding for the assessment or collection of any Taxes is pending 
against U.S. Tire or Tirus; (ii) no deficiency, assessment or other formal 
claim for any Taxes has been asserted or made against U.S. Tire of Tirus that 
has not been fully paid or finally settled; and (iii) no issue has been 
formally raised by any taxing authority in connection with an audit or 
examination of any return of Taxes.  No Federal, state or foreign income tax 
returns of U.S. Tire or Tirus have been examined since the 1996 
Reorganization, and there are no outstanding agreements or waivers extending 
the applicable statutory periods of limitation for such Taxes assessed during 
any such period.  No state Taxes will be assessed on or after the Closing 
Date against either Tirus or U.S. Tire for any tax period beginning after the 
1996 Reorganization and ending on or prior to the Closing Date, other than 
for 1997 and 1998, payment for which tax liabilities have been provided for 
by the parties hereto in the manner set forth in the Working Capital Note.  
For purposes of this Agreement, "Taxes" shall mean all taxes, charges, fees, 
levies or other assessments including, without limitation, income, excise, 
property, withholding, sales and 

<PAGE>

franchise taxes, imposed by the United States, or any state, county, local or 
foreign government or subdivision or agency thereof, and including any 
interest, penalties or additions attributable thereto.  With respect to the 
1997 North Carolina income tax return for 1997, WRI agrees to cause its 
accountants to prepare the return and to furnish the completed return to 
Purchaser for filing within 60 days after closing. 

               (b)  Neither U.S. Tire nor Tirus is a party to any Tax 
allocation or sharing agreement. 

               (c)  To the best knowledge of WRI, none of the assets of U.S. 
Tire or Tirus constitutes tax-exempt bond financed property or tax-exempt use 
property, within the meaning of Section 168 of the Code.  To the best 
knowledge of WRI, none of the U.S. Tire Entities are a party to any "safe 
harbor lease" that is subject to the provisions of Section 168(f)(8) of the 
Code as in effect prior to the Tax Reform Act of 1986, or to any "long-term 
contract" within the meaning of Section 460 of the Code. 

               (d)  At the Closing Date, neither U.S. Tire nor Tirus will 
have outstanding any warrants, options, convertible securities, or any other 
type of right granted, issued or otherwise created after the 1996 
Reorganization pursuant to which any person could acquire stock in U.S. Tire 
or a membership interest in Tirus that, if exercised or converted, would 
affect the Shareholders' acquisition or retention of ownership of more than 
eighty percent (80%) of the total 

<PAGE>

combined voting power of all classes of the WRI Delivered Stock and more than 
eighty percent (80%) of the total number of shares of each non-voting class 
of the WRI Delivered Stock. 

               (e)  Neither U.S. Tire, Tirus nor WRI is an investment company 
as defined in Section 368(a)(2)(F)(iii) and (iv) of the Code. 

               (f)  The fair market value of the assets of U.S. Tire exceeds 
the sum of its liabilities, plus the amount of liabilities, if any, to which 
the assets are subject. 

               (g)  Neither WRI, U.S. Tire nor Tirus is under jurisdiction of 
a court in a Title 11 or similar case within the meaning of Section 
368(a)(3)(A) of the Code. 

               (h)  Neither U.S. Tire, Recycling Partners, L.P. nor Tirus has 
any liability for Taxes for any entity or individual other than U.S. Tire or 
Tirus (i) as a transferee or successor, (ii) by contract or (iii) otherwise. 

          10.  CONTRACTS. The representations and warranties in this Section 
10 are limited to the extent that any Shareholder has actual or constructive 
knowledge which has not disclosed to a member of the WRI Board, other than a 
Shareholder, that (a) WRI will or is threatened to be in breach of any 
warranty on the Closing Date or (b) any representation contains any untrue 
statement of fact or omits to state a material fact necessary to make the 
statements herein, in light of the circumstances which they are made, not 
misleading.  U.S. Tire and Tirus are not in default in any material respect 
under any contract, lease, 

<PAGE>

arrangement and commitment (whether written or oral) to which either U.S. 
Tire and Tirus is a party or by which its assets or business are bound and 
the breach of which would have a materially adverse effect on the business, 
operations, properties, assets or conditions (financial or otherwise) of 
either company. 

          11.  LITIGATION AND RELATED MATTERS.  The representations and 
warranties in this Section 11 are limited to the extent that any Shareholder 
has actual or constructive knowledge which has not been disclosed to a member 
of the WRI Board, other than a Shareholder, that (a) WRI will or is 
threatened to be in breach of any warranty on the Closing Date or (b) any 
representation contains any untrue statement of fact or omits to state a 
material fact necessary to make the statements herein, in light of the 
circumstances which they are made, not misleading.  Except for the Lovelace 
Action, there are no actions, suits, proceedings or grievances pending 
against U.S. Tire and Tirus or, to the best knowledge of WRI, threatened 
against either company, in each event arising after the 1996 Reorganization, 
the business or any property or rights of either company, at law or in 
equity, before or by any arbitration board or panel, court or federal, state, 
municipal or other governmental department, commission, board, bureau, agency 
or instrumentality, domestic or foreign ("Agencies"), that could have a 
material adverse effect on the business, operations, properties, assets or 
conditions (financial or otherwise) of 

<PAGE>

U.S. Tire or Tirus or affects or would, if adversely determined, affect the 
right or ability of either company to carry on its business substantially as 
now conducted.  Neither U.S. Tire nor Tirus is subject to any continuing 
court or Agency order, writ, injunction or decree applicable specifically to 
either company's business, operations or assets or its employees, nor in 
default with respect to any order, writ, injunction or decree of any court or 
Agency with respect to its assets, business, operations or employees. 

          12.  COMPLIANCE WITH LAWS. The representations and warranties in 
this Section 12 are limited to the extent that any Shareholder has actual or 
constructive knowledge which has not been disclosed to a member of the WRI 
Board, other that a Shareholder, than (a) WRI will or is threatened to be in 
breach of any warranty on the Closing Date or (b) any representation contains 
any untrue statement of fact or omits to state a material fact necessary to 
make the statements herein, in light of the circumstances which they are 
made, not misleading.  Since the 1996 Reorganization, U.S. Tire and Tirus are 
and have been in compliance with all applicable laws, regulations (including 
federal, state and local procurement regulations), orders, judgments and 
decrees except where the failure to so comply would not have a material 
adverse effect on the business, operations, properties, assets or conditions 
(financial or otherwise) of either company. 

          13.  INSURANCE.  Since the 1996 Reorganization, U.S. 

<PAGE>

Tire has maintained the policies and contracts for fire, casualty, liability 
and other forms of insurance in existence on the closing date of the 1996 
Reorganization or has renewed or replaced such policies and contracts with 
policies and contracts with substantially similar coverage, deductibles and 
limits of insurance. All such policies are in full force and effect and shall 
remain in full force and effect until the Closing Date and are adequate for 
the business engaged in by the U.S. Tire.  U.S. Tire has not received any 
notice of cancellation or non-renewal or of significant premium increases 
with respect to any existing policy.  All premiums due prior to the date of 
this Agreement and the Closing Date for periods prior to the date of this 
Agreement and the Closing Date with respect to such policies have been timely 
paid. 

          14.  GOOD STANDING CERTIFICATES.  On or before the Closing Date, 
WRI, New U.S. Tire, Tirus and Recycling, L.P. each shall have delivered to 
the Purchaser a certificate, dated as of a recent date prior to the Closing 
Date, demonstrating that each of WRI, New U.S. Tire and Tirus is in good 
standing and authorized to do business in the state of incorporation of such 
entity.  

          15.  CAPITALIZATION. As of the date hereof, the authorized capital 
stock of the New U.S. Tire consists of (i) 10,000 shares of common stock, of 
which 1,000 shares are issued and outstanding.  All of such outstanding 
shares of capital stock are, or upon issuance will be, duly authorized, 
validly 

<PAGE>

issued, fully paid and nonassessable.   

          16.  SOLVENCY. At the present time, WRI reasonably believes it has 
the financial ability to meet all of the financial obligations imposed upon 
WRI under this Agreement.  WRI is solvent, able to meet its financial 
obligations and its assets exceed its liabilities. 

          17.  TITLE. The representations and warranties in this Section 17 
are limited to the extent that any Shareholder has actual or constructive 
knowledge which has not been disclosed to a member of the WRI Board, other 
than a Shareholder, that (a) WRI will or is threatened to be in breach of any 
warranty on the Closing Date or (b) any representation contains any untrue 
statement of fact or omits to state a material fact necessary to make the 
statements herein, in light of the circumstances which they are made, not 
misleading.  To the best of WRI's knowledge, since the 1996 Reorganization, 
no lien, encumbrance, covenant, condition or restriction has been created and 
touches and concerns the North Carolina landfill realty currently operated by 
WRI which materially interferes with or materially impairs its current 
operation.  

          18.  NO OTHER REPRESENTATIONS. Except to the extent set forth in 
this Agreement or expressly incorporated herein, WRI, New U.S. Tire, Tirus 
and Recycling, L.P. have made no representation or warranty whatsoever to the 
Shareholders or the other parties hereto and hereby disclaim all liability or 
responsibility for any other representation or warranty made, 

<PAGE>

communicated or furnished (orally or in writing) to the Shareholders and any 
other parties hereto or their representatives (including without limitation, 
any opinion, information, projection or advice as may have been or may be 
provided to the Shareholders and the other parties hereto or any of their 
affiliates by any director, officer, employee, agent, consultant or 
representative of WRI, New U.S. Tire, Tirus and Recycling, L.P.), including, 
without limitation, in connection with the 1996 Reorganization and all 
agreements, documents and instruments executed in connection therewith.

written instrument executed by all of the parties hereto.  No supplement,

the remaining provisions of this Agreement shall not in any way be affected 
or impaired thereby.

Agreement, each Shareholder will deliver stock certificates representing all

Representative to be held by it pursuant to the terms of the provisions set 
forth in the Release Agreement. 

     Section 7.     TERMINATION.  This Agreement shall terminate at 5:00 PM

               Pro Forma Working Capital Amount or the Final Working Capital
               Amount.  The Pro Forma Working Capital Amount, the Adjusted

<PAGE>

any of the following events (each an "Event of Default"):

               (i)   The failure of Maker to pay the Principal Payment by the 
date that the same becomes due and after the expiration of five (5) business 
days following Maker's receipt of written notice from the holder hereof that 
any such installment has not been received by the holder by such date; or

               (ii)  Maker shall voluntarily commence any case, proceeding or 
other action seeking reorganization, arrangement, adjustment, liquidation, 
dissolution or composition of its debts under any bankruptcy or insolvency 
law, or seeking the appointment of a receiver, trustee or custodian for him 
or for all of its property; or

               (iii) Any case, proceeding or other action shall be commenced

          (b)  Upon the occurrence of an Event of Default hereunder, the 
holder of this Promissory Note may declare the entire unpaid balance to be 
immediately due and payable upon written notice to Maker, and may, at its 
option, exercise any other right existing at law or in equity. Failure to 
exercise any such right or remedy shall not constitute a waiver of the right 
to exercise the same in the event of any subsequent default.

its terms and is placed in the hands of an attorney for collection, or if it

Principal Payments.  At the request of Payee and for a reasonable time after 
the maturity of this Note, Maker shall provide to Payee copies of all 
additional materials and other underlying data and documentation used in the 
calculation of the Principal Payments including, but not limited to, the 
applicable books and records of the Maker for its review and comment.

     8.    ACCOUNTING TERMS AND DETERMINATIONS.  All accounting terms used 
herein shall be interpreted, and all financial statements and certificates 
and reports as to financial matters required to be delivered to the Payee 
hereunder shall (unless otherwise disclosed to the Payee in writing at the 
time of delivery thereof in the manner described below) be prepared, in 
accordance with generally accepted accounting principles applied on a basis 
consistent with those used in the preparation of the latest financial 
statements prepared by Payee (which shall mean the financial statements as of 
August 31, 1998 attached hereto)(hereafter, "GAAP").  All calculations made 
for the purposes of determining Principal Payments hereunder shall be made by 
application of GAAP. Maker shall deliver to Payee at the same time as its 
delivery of any financial statements hereunder (i) a description in 
reasonable detail of any material variation between the application of 
accounting principles employed in the preparation of such statements and GAAP

arising as a consequence thereof.

or in connection with this Note shall be settled exclusively by arbitration, 
conducted before a panel of three (3) arbitrators in accordance with the 
rules of the American Arbitration Association then in effect.  Such 
arbitration, if requested by Payee, shall take place in North Carolina, and 
if requested by Maker, shall take place in Dallas, Texas.  The arbitrators 
shall not have the authority to add to, detract from, or modify any provision 
hereof nor to award punitive damages to any injured party.  The arbitrators 
shall have the authority to order refunds, additional payments, reimbursement 
of costs, including those incurred to review records or otherwise audit the 
calculations of Principal Payments hereunder, and interest thereon in the 
event the arbitrators determine that any calculation of Principal Payments 
was made without good faith, or that either party has otherwise materially 
breached this Note.  A decision by a majority of the arbitration panel shall 
be final and binding.  Judgment may be entered on the arbitrators' award in 
any court having jurisdiction.  The filing fee for any arbitration proceeding 
shall be borne equally by both parties.

               of North Carolina ("1997 Tax"); 
          2.   reduced to the extent that the 1997 Tax EXCEEDS the 1997
               Estimated Tax; 
          3.   reduced by an amount equal to the applicable corporate state
               income tax rate in the state of North Carolina times the taxable

          4.   decreased by the sum of all accounts receivables outstanding and

               not been paid as of April 30, 1999.

any other holder of this Promissory Note may from time to time designate as 
provided in Section 6 below, in installments as herein provided and in lawful 
money of the United States of America, the principal sum of Six Hundred 
Thousand and no/100 Dollars ($600,000.00), all as set forth below.

     2.   PAYMENTS.  The outstanding balance of this Promissory Note shall 
bear interest from the Closing Date at a rate equal to the Prime Rate plus 1% 
(the "Prime Rate" shall be equal to the then current published prime rate of 
Chase Bank, N.A. adjusted quarterly or, in the event Chase Bank, N.A. should 
cease to publish a prime rate, then by reference to a similar rate charged by 
a similar, national, banking institution).  Interest shall be paid quarterly, 
beginning on January 2, 1999 (each an "Interest Payment").  Principal shall 
be payable in four equal installments of One Hundred and Fifty Thousand 
Dollars ($150,000), on 6th day (or next business day if the 6th is not a 
business day) of the 15th, 18th, 21st and 24th months after the execution of 
this Promissory Note (each a "Principal Payment").
   
     2.   PREPAYMENT. This Promissory Note is subject to prepayment in whole 
or in part at any time after twelve (12) months from the date hereof at the 
option of the Maker by giving the holder thirty (30) days prior written 
notice of the Maker's intent to prepay this Promissory Note stating the date 
of prepayment and the amount of principal to be prepaid (the "Prepayment 
Notice").  Interest accrued to the prepayment date on the principal amount of 
this Promissory Note to be prepaid will be paid to the holder on the 
prepayment date.  

     3.   EVENTS OF DEFAULT; REMEDIES.

          (a)  At the option of the holder of this Promissory Note, the 
entire unpaid balance of this Promissory Note shall become due and payable 
upon written notice to Maker if there occurs any of the following events 
(each an "Event of Default"):

               (i)   The failure of Maker to pay any Interest Payment or 
Principal Payment by the date that the same becomes due and after the 
expiration of five (5) business days following Maker's receipt of written 
notice from the holder hereof that any such installment has not been received 
by the holder by such date; or

               (ii)  Maker shall voluntarily commence any case, proceeding or 
other action seeking reorganization, arrangement, adjustment, liquidation, 
dissolution or composition of 

<PAGE>

his debts under any bankruptcy or insolvency law, or seeking the appointment 
of a receiver, trustee or custodian for him or for all of his property; or

               (iii) Any case, proceeding or other action shall be commenced 
against Maker under any bankruptcy, insolvency or reorganization law or 
seeking the appointment of a receiver, custodian or trustee for Maker or for 
all of his property, and such case, proceeding or other action remains 
undismissed for a period of sixty (60) days after commencement thereof.

          (b)  Upon the occurrence of an Event of Default hereunder the 
holder of this Promissory Note may declare the entire unpaid balance to be 
immediately due and payable upon written notice to Maker, and may, at his 
option, exercise any other right existing at law or in equity. Failure to 
exercise any such right or remedy shall not constitute a waiver of the right 
to exercise the same in the event of any subsequent default.

     4.   ATTORNEYS' FEES.  If this Promissory Note is not paid pursuant to 
its terms and is placed in the hands of an attorney for collection, or if it 
is collected through bankruptcy or any other court proceeding after maturity, 
then any holder hereof shall be entitled to reasonable attorneys' fees for 
collection.

     5.   GOVERNING LAW AND VENUE.  THIS PROMISSORY NOTE IS BEING EXECUTED 
AND DELIVERED AND IS INTENDED TO BE PERFORMED IN THE STATE OF TEXAS.  THIS 
PROMISSORY NOTE SHALL BE CONSTRUED AS TO BOTH VALIDITY AND PERFORMANCE AND 
ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

                                        Exhibit "A" attached hereto and

     For value received and to secure the payment and performance of 
Grantors' obligations under the Agreement, Grantors convey the property to

property.  If Grantors perform all the covenants and pay all of the 
obligations under the Agreement, this deed of trust shall have no further 
effect, and Beneficiary shall release it at Grantors' expense.



GRANTORS' OBLIGATIONS

     Grantors agree to:

     1.   keep the property in good repair and condition;

     2.   pay all taxes and assessments on the property when due;

     3.   preserve the lien's priority as it is established in this deed of
trust;

     4.   maintain, in a form acceptable to Beneficiary, an insurance policy
that:

          a.   covers all improvements for their full insurable value as
          determined when the policy is issued and renewed, unless Beneficiary
          approves a smaller amount in writing;

          b.   contains an 80 % coinsurance clause;

          c.   provides fire and extended coverage, including windstorm
          coverage;

          d.   protects Beneficiary with a standard mortgage clause;

          e.   provides flood insurance at any time the property is in a flood
          hazard area; and 

4
<PAGE>

          f.   contains such other coverage as Beneficiary may reasonably
          require;

     5.   comply at all times with the requirements of the 80% coinsurance 
clause; 

     6.   deliver the insurance policy to Beneficiary and deliver renewals to 
Beneficiary at least ten days before expiration;

     7.   keep any buildings occupied as required by the insurance policy; and

     8.   if this is not a first lien, pay all prior lien notes that Grantors 
are personally liable to pay and abide by all prior lien instruments.


BENEFICIARY'S RIGHTS

     1.   Beneficiary may appoint in writing a substitute or successor 
trustee, succeeding to all rights and responsibilities of Trustee.

     2.   Beneficiary may apply any proceeds received under the insurance 
policy either to reduce the obligations under the Agreement or to repair or 
replace damaged or destroyed improvements covered by the policy.

     3.   If Grantors fail to perform any of their obligations under the 
Agreement or this deed of trust, Beneficiary may perform those obligations 
and be reimbursed by Grantors on demand at the place where the obligations 
under the Agreement are payable for any sums so paid, including reasonable 
attorneys' fees, plus interest on those sums from the dates of payment at the 
maximum rate permitted by applicable law for matured, unpaid amounts.  The 
sum to be reimbursed shall be secured by this deed of trust.

     5.   If Grantors default on the Agreement or fail to perform any of 
their obligations under the Agreement or this deed of trust or if default 
occurs on a prior lien note or other instrument, and the default continues 
after Beneficiary gives Grantors notice of the default and the time within 
which it must be cured, as may be required by law or by written agreement, 
then Beneficiary may:

          a.   declare the unpaid obligations under the Agreement and earned
          interest on such obligations immediately due;

          b.   request Trustee to foreclose this lien, in which case Beneficiary
          or Beneficiary's agent shall give notice of the foreclosure sale as
          provided by the Texas Property Code as then amended; and 

5
<PAGE>

          c.   purchase the property at any foreclosure sale by offering the
          highest bid and then have the bid credited on the obligations under
          the Agreement.


TRUSTEE'S DUTIES

     If requested by Beneficiary to foreclose this lien, Trustee shall:

     1.   either personally or by agent give notice of the foreclosure sale 
as required by the Texas Property Code as then amended;

     2.   sell and convey all or part of the property to the highest bidder 
for cash with a general warranty binding Grantor, subject to prior liens and 
to other exceptions to conveyance and warranty; and

     3.   from the proceeds of the sale, pay, in this order:

          a.   expenses of foreclosure, including a commission to Trustee of 5%
          of the bid; 

          b.   to Beneficiary, the full amount of the obligations under the
          Agreement, interest, attorneys' fees, and other charges due and
          unpaid, including, without limitation amounts due and unpaid under
          this deed of trust; 

          c.   any amounts required by law to be paid before payment to
          Grantors; and

          d.   to Grantors, any balance.


GENERAL PROVISIONS

     1.   If any of the property is sold under this deed of trust, Grantors 
shall immediately surrender possession to the purchaser.  If Grantors fail to 
do so, Grantors shall become a tenant at sufferance of the purchaser, subject 
to an action for forcible detainer.


6
<PAGE>

     2.   Recitals in any Trustee's deed conveying the property will be presumed
to be true.

     3.   Proceeding under this deed of trust, filing suit for foreclosure, 
or pursuing any other remedy will not constitute an election of remedies.

     4.   This lien shall remain superior to liens later created even if the 
time of payment of all or part of the obligations under the Agreement is 
extended or part of the property is released.

     5.   If any portion of the obligations under the Agreement cannot be 
lawfully secured by this deed of trust, payments shall be applied first to 
discharge that portion.

     6.   Grantors assign to Beneficiary all sums payable to or received by 
Grantors from condemnation of all or part of the property, from private sale 
in lieu of condemnation, and from damages caused by public works or 
construction on or near the property.  After deducting any expenses incurred, 
including attorneys' fees, Beneficiary may release any remaining sums to 
Grantors or apply such sums to reduce the obligations under the Agreement.  
Beneficiary shall not be liable for failure to collect or to exercise 
diligence in collecting any such sums.

     7.   Grantors assign to Beneficiary absolutely, not only as collateral, 
all present and future rent and other income and receipts from the property.  
Leases are not assigned.  Grantors warrant the validity and enforceability of 
the assignment.  Grantors may as Beneficiary's licensee collect rent and 
other income and receipts as long as Grantors are not in default under the 
Agreement or this deed of trust.  Grantors will apply all rent and other 
income and receipts to payment of the obligations under the Agreement and 
performance of this deed of trust, but if the rent and other income and 
receipts exceed the amount due under the Agreement and deed of trust, 
Grantors may retain the excess.  If Grantors default on the Agreement or fail 
to perform any of their obligations under the Agreement or this deed of 
trust, Beneficiary may terminate Grantors' license to collect and then as 
Grantors' agent may rent the property if it is vacant and collect all rent 
and other income and receipts.  Beneficiary neither has nor assumes any 
obligations as lessor or landlord with respect to any occupant of the 
property. Beneficiary may exercise Beneficiary's rights and remedies under 
this paragraph without taking possession of the property. Beneficiary shall 
apply all rent and other income and receipts collected under this paragraph 
first to expenses incurred in exercising Beneficiary's rights and remedies 
and then to Grantors' obligations under the Agreement and this deed of trust 
in the order determined by Beneficiary.  Beneficiary is not required to act 
under this paragraph, and acting under this paragraph does not waive any of 
Beneficiary's other rights or remedies.  If any Grantor becomes a voluntary 
or involuntary bankrupt, Beneficiary's filing a proof of claim in bankruptcy 
will be tantamount to the appointment of a receiver under Texas law.

     8.   Interest on the debt secured by this deed of trust shall not exceed 
the maximum amount of nonusurious interest that may be contracted for, taken, 
reserved, charged, or received under law; any interest in excess of that 
maximum amount shall be credited on the principal of the debt or, if that has 
been paid, refunded.  On any acceleration or required or permitted 
prepayment, any such excess shall be canceled automatically as of the 
acceleration or prepayment or, if already paid, credited on the principal of 
the debt or, if the principal of the debt has been paid, refunded.  

                                                                             0
<PAGE>

This provision overrides other provisions in this and all other instruments 
concerning the debt.

     9.   When the context requires, singular nouns and pronouns include the 
plural.

     10.  The Agreement includes all sums secured by this deed of trust.

     11.  This deed of trust shall bind, inure to the benefit of, and be 
exercised by successors in interest of all parties. 

     12.  Grantors represent that this deed of trust is given for the purpose 
of securing the payment and performance of their obligations under the 
Agreement.

                                   GRANTOR:

     Anderson (together with any successor appointed pursuant to SUBSECTION 5 
     below being hereinafter referred to as the "Representative") with full 
     power of substitution as such Shareholder's true and lawful agent and 
     attorney-in-fact with full power and authority in such Shareholder's 
     name, place and stead to (i) negotiate, determine and settle all matters 
     arising hereunder or in connection with any document related hereto, 
     including without limitation any action required or permitted to be 
     taken by the Shareholders or any of them under, or the resolution of any 
     dispute or other matter arising under the Option Agreement and (ii) 
     execute, swear to, acknowledge, deliver, file and record in the 
     appropriate public offices all certificates, documents and other 
     instruments (including, without limitation, this Agreement and any

     necessary under the terms of this Agreement or the laws of any state or 
     jurisdiction, and all certificates, documents and other instruments 
     which the Representative deems appropriate or necessary in the exercise 
     of its authority under (i) above.  In dealing with any Shareholder 
     hereunder, WRI shall be entitled to deal exclusively with the 
     Representative, and any action taken by the Representative may be 
     considered to be the action of each Shareholder with respect to which 
     such action was taken. All action taken by the Representative shall be 
     binding on all 

<PAGE>

     of the Shareholders, and no Shareholder shall have the right to object 
     to, dissent from, protest or otherwise contest the same. WRI shall be 
     permitted to rely upon any written instrument or documents executed by 
     the Representative as valid and binding upon all of the Shareholders.

          2.   The foregoing power of attorney is hereby declared to be 
     irrevocable and a power coupled with an interest and it shall survive 
     and not be affected by the subsequent death, incompetency, disability, 
     incapacity, dissolution or bankruptcy of such Shareholder and shall 
     extend to such Shareholder's heirs, transferees, successors, assigns and 
     personal representatives.

          3.   The Representative may consult with legal counsel, independent 
     accountants and other experts selected by it with respect to the 
     determination of any matters or the taking of any action referred to 
     herein and the Representative shall be fully justified and protected in 
     taking or omitting to take any action in good faith and in reliance on, 
     and in accordance with, the opinion or advice of such persons.  Each of 
     the Shareholders agrees to bear such Shareholder's proportionate share 
     of any compensation and expenses of such counsel, accountants or experts 
     or other out-of-pocket expenses incurred by the Representative in 
     carrying out its duties as herein provided, and upon receipt from time 
     to time of notices from the Representative as to any amounts to be so 
     paid by such Shareholder to make payment thereof, or reimburse the 
     Representative therefor, promptly as directed by the Representative.  
     Each of the Shareholders agrees to indemnify the Representative and hold 
     it 

<PAGE>

     harmless from any and all loss, damage or liability which it may sustain 
     as a result of any action taken in good faith.
     
          4.   Each Shareholder hereby irrevocably agrees that any action 
     required or permitted under this Agreement to be taken by the 
     Representative shall be valid and binding upon, and shall have the 
     effect as though taken by, such Shareholder hereunder, and in accordance 
     therewith the Representative may, on behalf of such Shareholder and in 
     his name, place and stead, accept payment of any amounts due and payable 
     to such Shareholder hereunder and make payment of any amount due and 
     payable from such Shareholder hereunder.
     
          5.   If the Representative shall be unable to perform the duties of 
     the Representative or shall resign from such position, the Shareholders, 
     who, as of the Closing Date hold a majority of the shares of capital 
     stock of the Company shall be entitled to designate a successor 
     Representative, who shall be the Representative for all purposes 
     thereafter.

          This Agreement is entered into as of the 13th day of October among 
Martin Bernstein ("Bernstein"), David Greenstein ("Greenstein"), Jay Anderson 
("Anderson", together with Bernstein and Greenstein, the "Principals"), 
Concord Recycling, L.L.C., a Delaware limited liability company ("Concord") 
and Waste Recovery, Inc., a Texas corporation ("WRI").

          Reference is hereby made to that certain Purchase Agreement (the 
"Purchase Agreement") to be entered into among WRI, Concord, New U.S. Tire, a 
Texas corporation ("New U.S. Tire"), U.S. Tire Recycling Partners L.P., a 
Delaware limited partnership ("Recycling L.P.") and Tirus Associates, L.L.C., 
a New York limited liability company ("Tirus", collectively with New U.S. 
Tire and Recycling L.P., the "U.S. Tire Entities").  All capitalized terms 
used and not otherwise defined herein shall have the meanings assigned to 
them in the Purchase Agreement

          WHEREAS, Pursuant to the terms of such Purchase Agreement, WRI has 
agreed to close on the date hereof, deferring delivery by Concord of certain 
items required to be delivered by Concord at the time of closing under the 
Purchase Agreement, the production of which is under the control of the 
Shareholders.

            WHEREAS, the Principals, due to their relationship with such 
Shareholders, are in a position to assist in the delivery of such items.

          NOW THEREFORE, in consideration of the mutual promises herein and 
for other valuable consideration, the adequacy of which is hereby 
acknowledged, the parties hereto do hereby agree as follows.
     
          1.   Each of the Principals hereby agree to cause the delivery by 
each of the Shareholders to Concord of the following items as soon as 
practicable from the date hereof, but within the time limits set forth in 
that certain Side Letter dated October 13, 1998 between WRI, Concord and the 
U.S. Tire Entities (the "Side Letter").
          
               a.   an executed copy of that certain Release Agreement (the 
"Release Agreement") dated as of October 13, 1998 between the Shareholders 
and WRI containing releases to WRI of its obligations under the Convertible 
Subordinate Notes and the 150 Note as well as the representations and 
warranties of the Shareholders set forth in B.10. of the Purchase Agreement;

               b.   the authorization to the Escrow Agent by each Shareholder 
directing the Escrow Agent to release and deliver all WRI Stock held by it 
pursuant to the terms 

<PAGE>

of the Escrow Agreement;

               c.   500,000 shares of WRI Stock currently held by the 
Shareholders and their assigns as set forth in the first column of Annex I to 
the Release Agreement;

               d.   an executed copy of the Option;

               e.   a cancelled copy of the Unsecured Note; and 

               f.   allonges from each holder (each a "Holder") of the notes 
(the "Notes") set forth opposite such holders name on Annex II to the Release 
Agreement, amending the terms of the Notes in substantially the form 
attached hereto as Exhibit A. 

          2.   Concord agrees to enter into an agreement with the Holders 
granting them the right/option to purchase a twenty five percent (25%) 
membership interest in Concord for an aggregate purchase price of $675,000 so 
long as any of the Notes remain unpaid, on terms and conditions mutually 
agreeable to the parties.  This option is in addition to the 15% membership 
interest granted to Tire Lending Associates ("TLA") upon payment of that 
certain promissory note dated October 13, 1998 made by Concord in favor of 
TLA.  In addition, Concord agrees to amend its operating agreement or other 
charter documents as required to comply with the terms of the agreement 
contemplated by this Section.

          3.   Each of the Principals shall indemnify and hold WRI harmless 
from any loss, cost or liability (including, but not limited to attorneys 
fees) due to the Principals' failure to comply with the terms of this 
Agreement. Bernstein and Anderson shall indemnify and hold Concord and 
Greenstein harmless from any loss, cost or liability (including, but not 
limited to attorneys fees) due to the their failure to comply with the terms 
of this Agreement PROVIDED, HOWEVER, that Berstein and Anderson shall have no 
obligation to indemnify Concord or Greenstein if such loss is due to 
Greenstein's failure to deliver any such items set forth in Paragraph 1. 
above in his capacity as a Shareholder or due to Concord's failure to deliver 
such items received by them to WRI and PROVIDED, FURTHER, that (i) Greenstein 
agrees to indemnify and hold Anderson and Bernstein harmless from any loss, 
cost or liability (including, but not limited to attorneys fees) due to the 
his failure to deliver any such items set forth in Paragraph 1. above in his, 
or Andrew Bodner's, capacity as a Shareholder and (ii) Concord agrees to 
indemnify and hold Anderson and Bernstein harmless from any loss, cost or 
liability (including, but not limited to attorneys fees) due to the their 
failure to deliver to WRI any items set forth in Paragraph 1. above which 
were timely delivered to Concord under the terms of this Agreement.

          4.   This Agreement along with the Release Agreement, the Purchase 
Agreement (and all Exhibit, Schedules and other agreements attached thereto), 
the Side Letter, the Option, the Tire Lending Note, the Deed of Trust and the 
Assignment and Assumption Agreement constitutes the entire agreement between 
the parties and supersedes all prior and written or oral communications, 
understandings or agreements regarding the subject matter 

<PAGE>

hereof.  This Agreement may not be amended, supplemented or modified in any 
respect except by the written agreement of the parties.  This Agreement may 
be executed in one or more counterparts, each of which shall be deemed an 
original, and all of which together shall constitute one and the same 
instrument.

          5.   This Agreement shall be construed, and the rights and 
obligations of the parties hereunder determined, in accordance with and 
governed by the internal laws of the State of New York (as permitted by 
Section 5-1401 of the New York General Obligations Law (or any similar 
successor provision)) without giving effect to any choice of law rule that 
would cause the application of the laws of any jurisdiction other than the 
internal laws of the State of New York to the rights and duties of the 
parties.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the 
date above.

     2.   WRI COVENANT NOT TO COMPETE.  WRI agrees that for a period of one 
(1) year following the date hereof, it shall not call upon, solicit, divert, 
take away or attempt to call upon, solicit, divert or take away any of those 
existing customers, suppliers, businesses or accounts of the U.S. Tire 
Recycling facility located in North Carolina (acquired by Concord from WRI 
pursuant to the Purchase Agreement) listed on Exhibit A (which shall be 
delivered to WRI within 30 days) to the extent that such customers transact 
business with the North Carolina facility (the "Concord Customers").  For 
purposes of this section, "existing customers, suppliers, businesses or 
accounts" shall mean any person or entity that has transacted business with 
the North Carolina facility at any time in the preceding 12 months.  This 
covenant is not intended to restrict WRI's right to develop and maintain 
business relationships with any Concord Customers that transacted or may 
transact business with any WRI facility outside the state of North Carolina.

     3.   ENFORCEMENT OF COVENANTS.  Each of the parties hereto acknowledges 
that a violation or attempted violation of any of the covenants and 
agreements in Sections 1 and 2 above will cause such damage to the other 
party as will be irreparable, the exact amount of which would be difficult to 
ascertain and for which there will be no adequate remedy at law, and 
accordingly, agrees that the other party shall be entitled as a matter of 
right to an injunction issued by any court of competent jurisdiction, 
restraining such violation or attempted violation of such covenants and 
agreements by such party, or the affiliates, partners or agents thereof, as 
well as recover from such party any and all costs and expenses sustained or 
incurred by the other party in obtaining such an injunction, including, 
without limitation, reasonable attorneys' fees.  Each of the parties hereto 
agrees that no bond or other security shall be required in connection with 
such injunction.  Each party represents and warrants that it has been 
represented by counsel in the negotiation and execution of this Agreement, 
including without limitation the provisions set forth above in this Section 3 
concerning the recovery of attorneys' fees.

     4.   INTELLECTUAL PROPERTY. Greenstein recognizes and agrees that, on 
and after the date hereof, he will not have the right to use for his own 
account any of the service marks, trademarks, trade names, licenses, 
procedures, processes, labels, trade secrets or customer lists that he may 
have obtained in connection with his employment with WRI.

     5.   VALIDITY.  To the extent permitted by applicable law, if it should 
ever be held that any provision contained herein does not contain reasonable 
limitations as to time, geographical area or scope of activity to be 
restrained, then the court so holding shall reform such provisions to the 
extent necessary to cause them to contain reasonable limitations as to time, 
geographical area and scope of activity to be restrained and to give the 
maximum permissible effect to the intentions of the parties as set forth 
herein; and the court shall enforce such provisions as so reformed.  If, 
notwithstanding the foregoing, any provision hereof is held to be illegal, 
invalid or unenforceable under present or future laws effective during the 
term hereof, such provision shall be fully severable; this Agreement shall be 
construed and enforced as if such illegal, invalid or unenforceable provision 
had never comprised a part hereof; and the remaining provisions hereof shall 
remain in full force and effect and shall not be affected by the illegal, 
invalid or enforceable provision or by its severance here from.  Furthermore, 
in lieu of such illegal, invalid or unenforceable provision there shall be 
added automatically as a part hereof a provision as similar in terms to such 
illegal, invalid or unenforceable provision as may be possible and be legal, 
valid and enforceable, and the parties hereby agree to such provision.

Gentlemen:

     I hereby resign as officer, director and employee of WRI, effective 
immediately, simultaneously with the closing of that certain Purchase 
Agreement between WRI and Concord Recycling, LLC, completed today.


                                        Sincerely,

                                                           FOR IMMEDIATE RELEASE
                                                                OCTOBER 15, 1998

                                       
                         WASTE RECOVERY, INC. ANNOUNCES
                        SALE OF ITS U.S. TIRE SUBSIDIARY


DALLAS, October 15 -- Waste Recovery, Inc. (OTC:WRII) (WRI or the Company), 
the leading American processor of scrap tires and producer of tire-derived 
fuel (TDF), announced today that it had sold its U.S. Tire subsidiary (UST), 
which operates a tire monofill in Concord, North Carolina, to David 
Greenstein, its former President and CEO who resigned from WRI and its Board 
contemporaneously with the closing of the sale.  WRI received a sales price 
consisting of cash, the forgiveness of debt, and shares of WRI in 
consideration of the sale of UST. While the transaction provides WRI with 
some needed liquidity and the relief of maturities of debt which had become 
due in less than one year, WRI expects to report a capital loss from the 
sales transaction.

With the departure of Mr. Greenstein and earlier this quarter, departures by 
Mr. Bernstein, WRI's former Chairman, and Jay Anderson, another Board member, 
all of whom joined WRI's Board in December 1996 in connection with the 
original acquisition of UST, management of WRI has been assumed by Thomas L. 
Earnshaw, Vice Chairman, WRI's former CEO.  A Board meeting has been 
scheduled in the near future to address the vacancies left by the departure 
of Messrs. Greenstein and Bernstein.

Contact:       Thomas L. Earnshaw
