         RE:      $11,500,000 Multiple Advance Term Loan Facility

Gentlemen:

         KTI, Inc. ("KTI") agrees to make advances to Oakhurst Company, Inc., a
Delaware corporation (the "Borrower" or "OCI"), for the benefit of Oakhurst
Technology, Inc., a Delaware corporation ("OTI") in an aggregate amount of up to
$11,500,000 (the "Facility Limit"), subject to adjustment as hereinafter set
forth, from now until April 30, 2001 under a promissory note dated the date of
this agreement (the "Note") upon the following terms and conditions:

         1. Making and Repaying the Advances; Interest Rate; Use of Proceeds.
The proceeds of each advance will be the used by the Borrower as an equity
investment in OTI, which is the designated "KTI Affiliate" under that certain
Investment Agreement dated as of December 29, 1998, between KTI and New Heights
Recovery & Power, LLC, a Delaware limited liability company ("New Heights") and
that certain Amended Plan of Reorganization for New Heights as confirmed and
modified by an order dated December 15, 1998 of the United States Bankruptcy
Court for the District of Delaware (the "Amended Plan"). The proceeds of each
advance shall be used by the Borrower only for equity contributions to OTI in
order to enable OTI (a) to satisfy its (or KTI's) obligations as the KTI
Affiliate and member of New Heights under the Amended Plan and Investment
Agreement, (b) to invest in businesses having the potential of expanding or
enhancing the recycling of rubber or tires, and (c) to reimburse (or to
contribute capital to New Heights to enable New Heights to reimburse or pay) KTI
for any drawings on or costs related to the BFI Letter of Credit (as defined
below), or the Acknowledgment (as defined below) including, without limitation,
loans made by KTI, Inc. to New Heights. Any equipment purchased (or moving costs
related to the moving of equipment) under the "Business Plan" described in the
Amended Plan shall
   2
be deemed advances under clause(a) of this paragraph 1, the amount thereof being
the cost or fair market value of such equipment; provided that the equipment
contributed from the "Franklin Park" facility (as described in the Business
Plan) shall be at the value designated in the Investment Agreement.

         KTI does not have to make any advance if an Event of Default (as
defined below) has occurred, if KTI has terminated its commitment under this
Agreement pursuant to paragraph 8 below or if any of the representations and
warranties of OCI or OTI in this Agreement would not be true if made on the date
of that advance. Also, KTI does not have to make any advance to the Borrower
until KTI has received (w) a duly executed Pledge Agreement dated as of the date
hereof, in the form of Exhibit A hereto (the "Pledge Agreement") pursuant to
which the Borrower pledges and grants a security interest in all of the issued
and outstanding capital stock of OTI to KTI to secure its obligations hereunder,
together with stock certificates and executed but undated stock powers or
assignments related thereto, and any other security agreements, other security
documents, financing statements, lien searches, opinions, certified resolutions,
opinions of counsel, or other documents or collateral that KTI may require, all
satisfactory to KTI, (x) a Non-exclusive License to Use Technology dated as of
the date hereof duly executed by OTI and KTI Recycling, Inc. (the "Royalty
Agreement"), (y)the Investment Agreement dated the date hereof (the "OCI
Investment Agreement") between KTI, OCI and OTI, and (z) an intercreditor
agreement with FINOVA Capital Corporation, in form and substance reasonably
acceptable to KTI (the "Intercreditor Agreement"). This Agreement, the Note, the
Pledge Agreement, the Royalty Agreement, the OCI Investment Agreement and the
Intercreditor Agreement are collectively referred to herein as the "Loan
Documents."

         The Borrower may prepay all or a portion of the Note at any time,
without premium or penalty. Amounts prepaid may not be reborrowed. All amounts
outstanding under the Note shall be due and payable in full on the earlier of
April 30, 2001 or the date KTI terminates its commitment under this Agreement
pursuant to paragraph 8 below.

         All amounts outstanding under the Note shall bear interest at the rate
of fourteen percent (14%) per annum, calculated on the basis of actual days
elapsed and a year of 360 days (the "Note Rate"). Interest shall be payable
quarterly in arrears, commencing with the calendar quarter ended March 31, 1999.
To the extent any interest is not paid in full when due, then the unpaid portion
shall be added to principal and bear interest at the Note Rate.

         2. Adjustments to Principal Amount. The Facility Limit will be
increased to an amount not to exceed $17,000,000 in the event (a)automatic
advances made under paragraph 7 cause the then-current Facility Limit to be
exceeded by the amount of such excess, and (b)the amount required by OTI to fund
the Business Plan under the Investment Agreement and the Amended Plan exceed the
sum of proceeds from the sale of common stock under the OCI Investment Agreement
plus all advances made under the then-current Facility Limit by the amount of
such excess. In such case, the Borrower shall execute and deliver a promissory
note to KTI in the principal amount of such increase, and otherwise having the
same terms as the
   3
Note, and deliver to KTI such authorizing resolutions, certificates of good
standing, opinions, reaffirmations and other documents related to the increase
requested by KTI.

     The Facility Limit will be decreased (x)by $7,500,000, in the event that
the Phase Two Business Plan (as defined in the Investment Agreement) is not
implemented by the time set forth in the Amended Plan, (y)by $3,500,000, in the
event that the Phase Three Business Plan (as defined in the Investment
Agreement) is not implemented by the time set forth in the Amended Plan, and
(z)by the cost of the acquisition of additional common stock of the Borrower in
the event the holders of certain stock options to purchase common stock of the
Borrower breach their agreement regarding the exercise of such options.

         3. Representations. The Borrower and OTI each represents and warrants
to KTI as follows:

                  a) It is a corporation duly organized, validly existing and in

         the Note, the Pledge Agreement and all other instruments and agreements
         executed by it in connection with this Agreement, and the other Loan

         action and do not require governmental approval.

                  c) The Loan Documents to which it is a party have been
         properly executed and constitute its legal, valid and binding
         obligations, enforceable against it in accordance with their terms.

         KTI fairly represent the Borrower's financial condition on the date of

         periods referred to in those statements. Those statements were prepared
         in accordance with generally accepted accounting principles. There have
         been no material adverse changes in the Borrower's properties or
         financial condition since the date of the latest statements.

                  e) There are no actions, suits or proceedings pending or
         threatened against or affecting the Borrower or the Borrower's

be prepared in accordance with generally accepted accounting principles,
consistently applied. The Borrower will also notify KTI within 30 days after any

         restrictions of record on the use of real property and landlord's liens

         from the value of such property or impair the use thereof in the
         business of the Borrower, and capitalized leases provided that the
         aggregate annual payments owed by the Borrower under such capitalized

                  e) Sell any property subject to liens of KTI, sell any of the
         Borrower's assets if such sale will materially and adversely affect the
         Borrower's ability to repay advances made to Borrower by KTI or sell

         7. KeyBank Letter of Credit and Acknowledgment; Automatic Advances. As
contemplated by paragraph 6 of Article XIII of the Amended Plan, KTI has caused
KeyBank National Association ("KeyBank") to issue a letter of credit (the "BFI
Letter of Credit") to Browning-Ferris Industries of Illinois, Inc. ("BFI") for
the account of KTI, in order to secure and provide for reimbursement to BFI for
the costs of New Heights' remediation obligations relating to the current
stockpile of tire pieces in the event BFI performs such obligations. KTI has
agreed to reimburse and pay all fees to KeyBank relating to the BFI Letter of
Credit, including reimbursement of any drawings thereunder. KTI has executed and
delivered to New Heights an acknowledgment to fund the obligations of OTI under
the Investment Agreement (the "Acknowledgment"). OTI hereby agrees to make a
capital contribution to New Heights to enable New Heights to pay or reimburse
KTI for any amounts paid by KTI in connection with the BFI Letter of Credit or
the Acknowledgment. KTI is hereby authorized, without request or notice of any
kind, to automatically make advances of the Loan hereunder to itself to
reimburse itself for any payments to KeyBank with respect to the BFI Letter of
Credit or for payment or performance by KTI under the Acknowledgment, including
all reasonable expenses relating thereto, and to the extent the Facility Amount
is then insufficient to fund such advances, the Facility Amount will be
automatically increased to provide for such advances.

         8. Events of Default Each of the following shall be an Event of
Default:

                  a) The Borrower shall fail to pay when due any amount owing on
         any Note or any other indebtedness to KTI that the Borrower owes or has
         guaranteed.

                  b) Any event referred to in any Note that permits KTI to
         declare that Note due and payable shall occur.

                  c) The Borrower shall breach any of the Borrower's other
         obligations under this Agreement and such breach shall continue for 30
         days after KTI gives the Borrower notice thereof.

                  d) An event of default shall occur under any of the Loan
         Documents or any other document securing any Note, or under the FINOVA
         Agreement.

                  e) Any representation or warranty that the Borrower has made
         under this Agreement or any other Loan Document shall prove to have
         been untrue when made.
   7
                  f) The Borrower or OTI shall become insolvent, or the subject
         of any bankruptcy, reorganization, debt arrangement, dissolution or
         liquidity proceeding.

         If any Event of Default described in clause f) above occurs, KTI's
commitment under this Agreement shall automatically terminate and the Notes and
all of the Borrower's other obligations to KTI under this Agreement shall
immediately become due and payable. If any other Event of Default occurs, KTI
may, without giving the Borrower notice, declare KTI's commitment to make
advances under this Agreement terminated and/or declare the principal balance of
each Note and all accrued interest to be immediately due, and KTI may exercise
any other rights and remedies available to KTI by law or agreement. The Borrower
hereby irrevocably authorizes KTI to set off all sums owing by the Borrower to
KTI against all deposits and credits the Borrower may have with, and any claims
the Borrower may have against, KTI at any time after an Event of Default occurs.

         9. Fees and Expenses The Borrower and OTI agree to pay all of the costs
and expenses incurred by KTI in connection with the negotiation, preparation,
execution, perfection, administration, amendment, or enforcement of this
Agreement and the other Loan Documents, including attorney's fees and expenses
and internal time charges reasonably determined by KTI for lawyers employed by
KTI.

         10. Miscellaneous

                  a) If KTI does not exercise some right KTI has against the
         Borrower, or if KTI delays in exercising a right, that does not mean
         that KTI gives up that right.

                  b) No Loan Document can be changed unless KTI signs or
         consents in writing to a written amendment.

                  c) This Agreement is the entire agreement between KTI and the
         Borrower with respect to the $11,500,000 line of credit. This Agreement
         takes the place of any conversations, oral agreements and commitment
         letters or other letters between KTI and the Borrower.

                  d) This Agreement shall be binding upon the Borrower and OTI,
         and their successors and assigns, and shall inure, together with the
         rights and remedies of KTI hereunder, to the benefit of, and be
         enforceable by, KTI and its successors, transferees and assigns.
         Without limiting the generality of the foregoing, KTI may assign or
         otherwise transfer all or any portion of its rights and obligations
         under the Credit Agreement and the Loan Documents to any other Person.

                  e) Each of the Borrower and OTI agrees to the provisions
         contained in Exhibit B attached hereto, which provisions are fully
         incorporated herein.

                                    EXHIBIT B

       Joint and Several Obligations; Terms with Respect to Obligations.

         If it is at any time determined that either OCI or OTI is liable as a
guarantor with respect to such Obligations arising in connection with Loan or
advances made to the other (the "Guaranteed Obligations"), each of OCI and OTI
hereby agrees to the following terms:

                  (a) Obligations Absolute. No act or thing need occur to
         establish the liability of OCI or OTI for the Guaranteed Obligations,
         and no act or thing, except full payment and discharge of all such
         Guaranteed Obligations, shall in any way exonerate OCI or OTI or
         modify, reduce, limit or release the liability of OCI or OTI for its
         Guaranteed Obligations. The obligations of OCI or OTI for its
         Guaranteed Obligations shall be absolute, unconditional, and
         irrevocable, and shall not be subject to any right of setoff or
         counterclaim by OCI or OTI.

                  (b) Continuing Guaranty . OCI and OTI shall each be liable for
         its Guaranteed Obligations, plus accrued interest thereon and all
         attorneys' fees, collection costs and enforcement expenses referable
         thereto. Guaranteed Obligations may be created and continued in any
         amount without affecting or impairing the liability of OCI or OTI
         therefor. No notice of such Guaranteed Obligations already or hereafter
         contracted or acquired by KTI, or any renewal or extension of any
         thereof need be given to OCI or OTI and none of the foregoing acts
         shall release OCI or OTI from liability hereunder. The agreement of OCI
         or OTI pursuant to the Credit Agreement with respect to its Guaranteed
         Obligations is an absolute, unconditional and continuing guaranty of
         payment of such Guaranteed Obligations and shall continue to be in
         force and be binding upon OCI or OTI until such Guaranteed Obligations
         are paid in full and the Credit Agreement is terminated, and KTI may
         continue, at any time and without notice to such Borrower, to extend
         credit or other financial accommodations and loan monies to or for the
         benefit of the other on the faith thereof. Each of OCI and OTI hereby
         waives, to the fullest extent permitted by law, any right they may have
         to revoke or terminate its guaranty of the Guaranteed Obligations
         before the Guaranteed Obligations are paid in full and the Credit
         Agreement is terminated. In the event either OCI or OTI shall have any
         right under applicable law to otherwise terminate or revoke its
         guaranty of the Guaranteed Obligations which cannot be waived, such
         termination or revocation shall not be effective until written notice
         of such termination or revocation, signed by person, is actually
         received by KTI's officer responsible for such matters. Any notice of
         termination or revocation described above shall not affect OCI's or
         OTI's guaranty of the Guaranteed Obligations in relation to (i) any of
         the Guaranteed Obligations that arose prior to receipt thereof or (ii)
         any of the Guaranteed Obligations created after receipt thereof, if
         such Guaranteed Obligations were incurred through loans by KTI , and/or
         for the purpose of protecting any collateral, including, but not
         limited, to all protective advances, costs, expenses, and attorneys'
         and paralegals' fees, whensoever made, advanced or incurred by KTI in
         connection with the Guaranteed Obligations. If, in reliance on either
         OCI or OTI's guaranty of its
   11
         Guaranteed Obligations, KTI makes loans or other advances to or for the
         benefit of the other or takes other action under this Agreement after
         such aforesaid termination or revocation by the undersigned but prior
         to the receipt by KTI of said written notice as set forth above, the
         rights of KTI shall be the same as if such termination or revocation
         had not occurred.

                  (c) Other Transactions. Whether or not any existing
         relationship between OCI and OTI has been changed or ended, KTI may,
         but shall not be obligated to, enter into transactions resulting in the
         creation or continuance of other obligations of the other to KTI,
         without consent or approval by the other and without notice to the
         other, and all such obligations shall be guaranteed by virtue of the
         Credit Agreement. The liability of OCI and OTI under the Credit
         Agreement with respect to the Guaranteed Obligations shall not be
         affected or impaired by any of the following acts or things (which KTI
         is expressly authorized to do, omit or suffer from time to time,
         without notice to or approval by OCI or OTI): (i) any acceptance of
         collateral security, other guarantors, accommodation parties or
         sureties for any or all Guaranteed Obligations; (ii) any one or more
         extensions or renewals of Guaranteed Obligations (whether or not for
         longer than the original period) or any modification of the interest
         rates, maturities or other contractual terms applicable to any
         Guaranteed Obligations; (iii) any waiver or indulgence granted to the
         other Borrowers, any delay or lack of diligence in the enforcement of
         Guaranteed Obligations, or any failure to institute proceedings, file a
         claim, give any required notices or otherwise protect any Guaranteed
         Obligations; (iv) any full or partial release of, settlement with, or
         agreement not to sue,OCI or OTI or any other guarantor or other person
         liable in respect of any Guaranteed Obligations; (v) any discharge of
         any evidence of Guaranteed Obligations or the acceptance of any
         instrument in renewal thereof or substitution therefor; (vi) any
         failure to obtain collateral security for Guaranteed Obligations, or to
         see to the proper or sufficient creation and perfection thereof, or to
         establish the priority thereof, or to protect, ensure, or enforce any
         collateral security, or any modification, substitution, discharge,
         impairment or loss of any collateral security; (vii) any foreclosure or
         enforcement of any collateral security; (viii) any transfer of any

         any release of any collateral security for Guaranteed Obligations; (xi)
         any amendment to or modification of, any agreement between KTI and
         either OCI or OTI, or any waiver of compliance by OCI or OTI with the
         terms thereof; and (xii) any election by KTI under Section  1111(b) of
         the United States Bankruptcy Code.

                  (d) Waivers of Defenses and Rights. Each of OCI and OTI waives
         any and all defenses, claims and discharges of the other, or any other
         obligor, pertaining to the Guaranteed Obligations, except the defense
         of discharge by payment in full. Without limiting the generality of the
         foregoing, neither OCI nor OTI will assert, plead or enforce against
         KTI any defense of waiver, release, discharge in bankruptcy, statute of
         limitations, res judicata, statute of frauds, anti-deficiency statute,
         fraud, usury, illegality or unenforceability which may be available to
         OCI or OTI or any other person liable in respect of any Guaranteed
         Obligations, or any setoff available against KTI to OCI or
   12
         OTI or any such other person, whether or not on account of a related
         transaction. Each of OCI and OTI expressly agrees that it shall be and
         remain liable for any deficiency remaining after foreclosure of any
         security interest securing Guaranteed Obligations, whether or not the
         liability of or any other obligor for such deficiency is discharged
         pursuant to statute, judicial decision or contract. Each of OCI and OTI
         waives presentment, demand for payment, notice of dishonor or
         nonpayment, and protest of any instrument evidencing Guaranteed
         Obligations. Each of OCI and OTI agrees that its liability under the
         Credit Agreement for the Guaranteed Obligations shall be primary and
         direct, and that KTI shall not be required first to resort for payment
         of the Guaranteed Obligations to the other or other persons or their
         properties, or first to enforce, realize upon or exhaust any collateral
         security for the Guaranteed Obligations, or to commence any action or
         obtain any judgment against any other or against any such collateral
         security or to pursue any other right or remedy KTI may have against
         any other before enforcing the liability of such Person for the
         Guaranteed Obligations under the Credit Agreement.

                  (e) Approval of Credit. Each of OCI and OTI has, independently
         and without reliance upon KTI or the directors, officers, agents or
         employees of KTI, and instead in reliance upon information furnished by
         the other Borrowers and upon such other information as OCI or OTI
         deemed appropriate, made its own independent credit analysis and
         decision to guaranty the obligations of the other Borrowers pursuant to
         the Credit Agreement.

                  (f) Waiver of Subrogation. Each of OCI and OTI expressly
         waives any and all rights of subrogation, reimbursement, indemnity,
         exoneration, contribution or any other claim which it may now or
         hereafter have against the other, any endorser or any other guarantor
         of all or any part of the Guaranteed Obligations, and each hereby
         waives any benefit of, and any right to participate in, any security or
         collateral given to KTI to secure payment of the Guaranteed Obligations
         or any other liability of the other to KTI. Each of OCI and OTI further
         agrees that any and all claims it may have against the other, any
         endorser or any other guarantor of all or any part of the Guaranteed
         Obligations or against any of their respective properties, whether
         arising by reason of any payment by such Person to KTI pursuant to the
         provisions hereof or otherwise, is hereby waived.
