terms and conditions herein set forth, the Bank agrees at any time and from

make and maintain a loan or loans up to a maximum of $8,000,000.00 (each a
"Revolving Credit Loan" and collectively, the "Revolving Credit Loans") to the
Company.  Revolving Credit Loans may be repaid and reborrowed in accordance
with the provisions hereof and shall, in the aggregate, not exceed the lesser
of (i) $8,000,000.00 or (ii) the Borrowing Base.  There shall be no further
advances of any Revolving Credit Loans after the Maturity Date.

                 SECTION 2.02.   Advances Under the Revolving Credit Loan.
The Bank shall, from time to time, make Revolving Credit Loans to the Company
in the form of advances to the Company or third parties for the sole purpose of

name the Company as maker or drawer thereon and are presented to the Bank by
the Company or such third parties.  The Bank shall not make any other Revolving
Credit Loans except pursuant to Section 2.09(a).

                 SECTION 2.03.   The Term Loan.  Subject to the terms and
conditions herein set forth, the Bank agrees to lend to the Company a term loan
of up to $27,000,000.00 (the "Term Loan" and, together with the Revolving
Credit Loan, any advances under a Letter of Credit described in Article III
hereof and any amounts owing under the Fee Capitalization Note, the "Loans").
The Term Loan evidences amounts owed to the Bank under the Prior Agreements.

                 SECTION 2.04.   [Intentionally Omitted]

                 SECTION 2.05.   Notes.  (a)  The Company's obligation to pay

                 (b)      The Company's obligation to repay the Term Loan shall

                 SECTION 2.06.   Payment of Interest.  (a) Prior to a Default
hereunder, the Company agrees that interest shall accrue in respect of the
unpaid principal amount of the Revolving Credit Loan and the Term Loan from the
date of the making of each such Loan to maturity (whether by acceleration or
otherwise) at a rate per annum which shall at all times be equal to the lesser
of (i) the Highest Lawful Rate and (ii) the applicable Margin plus the
Alternate Base Rate in effect from time to time; provided, the Company agrees
that it shall only be required to pay interest at a rate per annum equal to the
lesser of (x) the Highest Lawful Rate and (y) the Alternate Base Rate; and
provided further, the Company agrees that any accrued interest which is not
required to be paid hereunder shall be capitalized and added to the principal
balance of the Fee Capitalization Note.  If the Alternate Base Rate is based on
the Prime Rate, interest shall be computed on the basis of the actual number of
days elapsed over a year of 365 or 366 days, as the case may be.  If the
Alternate Base Rate is based on the Federal Funds Effective Rate, interest
shall be computed on the basis of the actual number of days elapsed over a year
of 360 days.  Prior to a Default hereunder, the Company agrees that interest
shall accrue in respect of the unpaid principal amount outstanding under the
Fee Capitalization Note as provided therein.  Upon the occurrence of a Default
hereunder, all outstanding principal under any Loan shall accrue at the Highest
Lawful Rate.

                 (b)      Overdue principal and, to the extent permitted by
law, overdue interest in respect of each Loan and all other overdue amounts
owing hereunder shall bear interest for each day that such amounts are overdue
at a rate per annum equal to the Highest Lawful Rate.

                 (c)      Interest on each Loan shall accrue from the date of
such Loan to the date of any repayment thereof and shall be payable in
accordance with the above provisions (i) on each Designated Payment Date and
(ii) on the date of any voluntary or mandatory prepayment and (iii) at
maturity.

                 SECTION 2.07.  Required Payments of Principal.  (a) All
outstanding principal (and any accrued, unpaid interest) on the Revolving
Credit Note shall be due and payable on the  Maturity Date.

                 (b)      Outstanding principal on the Term Note shall be due
and payable as follows:

                          (i)     a principal payment of $1,000,000.00 shall be
                 due and payable (A) on the date one hundred eighty (180) days
                 after the start of operations at that particular facility
                 operated in the State of California and commonly referred to
                 as "Ward Valley" and (B) every quarterly date following such
                 initial payment; provided, however, if any such payment date
                 shall be a day which is not a Business Day, such payment date
                 shall be the next succeeding Business Day; and





                                      -14-
   20
                          (ii)   all remaining outstanding principal and any 
                 accrued, unpaid interest shall be due on the Maturity Date.

                 (c)      In addition to the amounts required under (b) above,
the following principal payments shall be due on the Term Note:

                          (i)     (A) one hundred percent (100%) of the net
                 proceeds of the sale of any of the Collateral (other than (y)
                 inventory sold in the ordinary course of business and (z)
                 Permafix Stock, which is provided for in the Pledge
                 Agreements), (B) one hundred percent (100%) of the net
                 proceeds of the sale of any assets of any Loan Parties that

                 the net proceeds of the sale of any assets of any Loan Parties
                 that are not Collateral (to the extent such sales do not
                 exceed $500,000.00 in the aggregate), shall be due and payable
                 on the Term Note immediately upon receipt, which amounts shall
                 not reduce the required payments described above;

                          (ii)    any funds received as insurance proceeds in
                 connection with damage to American Ecology Recycle Center,
                 Inc., a subsidiary of the Company, which are in excess of the
                 cost to rebuild and refurbish the damaged facility which
                 amounts will not reduce the required payments described above;

                          (iii)   any funds received as business interruption
                 insurance proceeds up to an amount equal to one hundred
                 percent (100%) of the proceeds received in connection with the
                 liquidation of WPI Transportation, Inc., a subsidiary of the
                 Company, which amounts will not reduce the required payments
                 described above;

                          (iv)    one hundred percent (100%) of the net
                 proceeds of any industrial development bond financing for
                 American Ecology Recycle Center, Inc., a subsidiary of the
                 Company (and only if the gross proceeds from such industrial
                 revenue bond financing are equal to or greater than
                 $10,000,000.00 and one hundred percent (100%) of the net
                 proceeds therefrom are applied to the Term Loan as required
                 hereby, the Agent shall release, on behalf of the Banks, all
                 of the pledged assets of American Ecology Recycle Center,
                 Inc., a subsidiary of the Company);

                          (v)     any funds received from any entity as
                 reimbursement for permit costs incurred in the State of
                 Nebraska; and

                          (vi)    within 10 days after the Bank receives the
                 financial statements required to be delivered by the Company
                 pursuant to Section 7.01(b) beginning

                 by a Subsidiary of the Company and (I) any increase (from the
                 Effective Date) in the amount of marketable securities pledged
                 by the Company as security for its obligations, and adding
                 thereto (Y) the proceeds obtained from any equity or debt

                 the Loan Parties which are not required to be paid under clause

                 (d)      In addition to all other payments required by this

Revolving Credit Note on any day to the extent that the aggregate outstanding

                 (e)      Each repayment pursuant to this Section which is not
specifically characterized as a repayment of principal shall be applied first,
to the payment of accrued and unpaid interest, and then to the outstanding
principal of the Loans.

                 SECTION 2.08.   Voluntary Prepayments.  The Company shall
have the right to voluntarily prepay the Loans (other than the Fee
Capitalization Note which may not be prepaid without the consent of the Bank)

                 SECTION 2.09.   Method and Place of Payment.  (a) The Company
shall enter into a Cash Management and Lock Box Agreement (the "Cash Management
and Lock Box Agreement") with the Bank whereby all of the Company's accounts

right, but not the obligation, and the Company hereby grants the Bank the
right, to deduct and set-off any amounts owing to the Bank under this Agreement
from the collections made pursuant to the above-referenced Cash Management and
Lock Box Agreement.  All collected funds





                                      -16-
   22
in account number 00100354902 will be swept daily by the Bank and applied
first, against any accrued interest which is due and payable, second, against
any principal amounts which are due and payable under the Term Loan, the
Revolving Credit Loan or any Letter of Credit and third, against the
outstanding principal balance of the Revolving Credit Loan.  If at any time any
payments are owing by the Company to the Bank and funds in the above referenced
account are insufficient to satisfy the same, the Company shall make such
payment to the Bank immediately upon demand therefor by the Bank.  Any
chargebacks or other debits subsequently affecting said funds or account shall
adjust the subsequent balance of the account, or if same is insufficient, will
allow the Bank to make an advance, at its sole option, to allow payment of such
items.

                 (b)      The Company irrevocably authorizes the Bank to make,
and irrevocably appoints the Bank as its attorney-in-fact (which power shall be
coupled with an interest), to make transfers of funds to and from the Cash
Management and Lockbox Account, any other (except special trust, pension and
tax accounts) account of the Company, or any of them, necessary to accomplish
the purposes of the Loan Documents.

                 SECTION  2.10.   Increased Taxes or Costs.  (a) If the Bank
shall have determined in good faith that any law, rule, regulation or guideline
regarding required reserves or reserve percentages, capital adequacy, or any
change therein, or any change in the interpretation or administration thereof
or compliance by the Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency  has or would have the effect of reducing the
rate of return on the capital of the Bank as a consequence of its obligations
hereunder to a level below that which it could have achieved but for such
adoption, change or compliance by an amount deemed to be material, then, from
time to time, the Company shall pay to the Bank such additional amount or
amounts as will reasonably compensate the Bank for such reduction.

                 (b)      The Bank will notify the Company of any event which
will entitle it to compensation pursuant to this Section, promptly provided,
the Company shall not be obligated hereunder for any such amounts in respect of
changes occurring more than ninety (90) days prior to the date of such notice.
A certificate of a Bank setting forth in reasonable detail (i) such amount or
amounts as shall be necessary to compensate the Bank as specified in paragraph
(a) above, as the case may be, and (ii) the calculation of such amount or
amounts, shall be delivered to the Company and shall be conclusive absent
manifest error.  The Company shall pay to the Bank the amount shown as due on
any such certificate as will reasonably compensate the Bank for such matters
within thirty (30) days after its receipt of the same.

                 (c)      Failure on the part of the Bank to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
the Bank's rights to demand compensation for any increased costs or reduction





                                      -17-
   23
in amounts received or receivable or reduction in return on capital, provided,
the Bank shall be entitled to collect such costs or expenses only in regard to
change in circumstances occurring after the Effective Date.

                                  ARTICLE III

                               LETTERS OF CREDIT

                 SECTION 3.01.   Letters of Credit.  (a) Subject to and upon
the terms and conditions herein set forth, the Bank agrees that it will, at any
time and from time to time on or after the Effective Date and prior to the
Maturity Date, following its receipt of a Letter of Credit Request, and
satisfaction of the conditions described in Section 3.02 below, issue for the
account of the Company and in support of the obligations of the Company, one or
more irrevocable standby, but not commercial, letters of credit (all such
letters of credit together with any existing letters of credit previously
issued by the Bank, collectively, the "Letters of Credit"), up to a maximum
total outstanding and/or drawn upon at any one time of $5,000,000.00.  All
Letters of Credit shall be Standby Letters of Credit and have a maturity date
not later than the Letter of Credit Termination Date.

                 (b)      The Bank shall not issue, renew or permit the renewal
of any Letter of Credit if (i) any of the conditions precedent to such issuance
or renewal set forth in Section 5.02 are not satisfied, (ii) the expiry date is
a date that is later than one (1) year after the date of issuance or renewal,
as the case may be, (iii) the expiry date is a date that is later than the
Maturity Date, unless such Letter of Credit is secured by Letter of Credit
Collateral, (iv) after giving effect to such renewal, the expiry date of such
Letter of Credit would be a date that is later than the Letter of Credit
Termination Date or (v) if the Letter of Credit Collateral for such Letter of
Credit is not received by and pledged to the Bank in a manner satisfactory to
the Bank in its sole discretion.

                 SECTION 3.02.   Letter of Credit Requests.   Whenever the
Company desires that a Letter of Credit be issued for its account or that the
existing expiry date of a Letter of Credit shall be extended, it shall give the
Bank at least two Business Days' prior written request therefor.  Each such
request shall be in the form of an Application for Letter of Credit on the
Bank's standard form therefor, completed to the satisfaction of the Bank,
shall be accompanied by the Letter of Credit Collateral, pledged to the Bank in
a manner satisfactory to the Bank in its sole discretion,  and such other
certificates, documents and other papers and information as the Bank may
reasonably request.  Each Letter of Credit shall be in such form as may be
reasonably approved from time to time by the Bank and the Company.

                 SECTION 3.03.   Repayment of Letter of Credit Drawings.  (a)
The Company hereby agrees to reimburse the Bank by making payment to the Bank
in immediately available funds, for





                                      -18-
   24
any payment made by the Bank under any Letter of Credit issued by it (each such
amount so paid until reimbursed, an "Unpaid Drawing") immediately after, and in
any event on the date of, such payment prior to 2:00 p.m. (Houston, Texas time)
on the date of such payment, from and including the date paid to but excluding
the date reimbursement is made as provided above, at a rate per annum equal to
the Highest Lawful Rate, such interest to be payable on demand.  Failure to
make such payment shall (i) constitute a Default hereunder and (ii) allow the
Bank, in its sole discretion, to make a Revolving Credit Loan under the
Revolving Credit Note to effect such repayment.

                 (b)      The Company's obligations under this Section 3.03 to
reimburse the Bank with respect to Unpaid Drawings (including, in each case,
interest thereon) shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to
payment which the Company may have or have had against the Bank, including any
defense based upon the failure of any drawing under a Letter of Credit (each a
"Drawing") to conform to the terms of the Letter of Credit or any
non-application or misapplication by the beneficiary of the proceeds of such
Drawing.  The issuance of a Letter of Credit shall reduce the amount available
for future Letters of Credit by the face amount of the Letter of Credit issued.
Additionally, all Letters of Credit outstanding under either of the Prior
Agreements shall be considered Letters of Credit hereunder and shall reduce the
amount of Letters of Credit available to be issued by the face amount thereof.

                 SECTION 304.  Rights of Bank Regarding Letters of Credit.
The Bank shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions caused by the Bank's willful misconduct.  IT IS THE EXPRESS INTENTION
OF THE PARTIES HERETO THAT THE BANK, ITS OFFICERS, DIRECTORS, EMPLOYEES AND
AGENTS SHALL BE INDEMNIFIED AND HELD HARMLESS FROM ANY ACTION TAKEN OR OMITTED
BY SUCH PERSON UNDER OR IN CONNECTION WITH ANY LETTER OF CREDIT OR ANY RELATED
DRAFT OR DOCUMENT ARISING OUT OF OR RESULTING FROM SUCH PERSON'S SOLE OR
CONTRIBUTORY NEGLIGENCE.  The Company agrees that any action taken or omitted
by the Bank under or in connection with any Letter of Credit or the related
drafts or documents, if done in accordance with the standards of care specified
in the Uniform Customs and Practice for Documentary Credits (1993 Revision),
International Chamber of Commerce, Publication No. 500 (and any subsequent
revisions thereof approved by a Congress of the International Chamber of
Commerce and adhered to by the Bank) and, to the extent not inconsistent
therewith, the Uniform Commercial Code of the State of Texas, shall not result
in any liability of the Bank to the Company or any other Loan Party.

                 SECTION 3.05.   Increased Letter of Credit Costs.
Notwithstanding any other provision herein, but subject to Section 11.08, if
the Bank shall determine in good faith that any change in any law, rule,
regulation or guideline (whether or not having the force of law) either (i)
shall impose, modify or make applicable any reserve, deposit, capital adequacy
or similar requirement against letters of credit issued, or participated in, by
the Bank or (ii) shall impose on the





                                      -19-

the result of any of the foregoing is to increase the cost to the Bank of
issuing, maintaining or participating in any Letter of Credit, or reduce the
amount received or receivable by the Bank hereunder with respect to Letters of
Credit, by an amount deemed to be material, then, from time to time, the
Company shall pay to the Bank such additional amount or amounts as will
reasonably compensate such Bank for such increased cost, provided, the Bank
shall notify the Company of such change promptly and the Company shall not be
obligated hereunder for any such amounts in respect of changes occurring more
than ninety (90) days prior to the date of any such notice.

used to repay the Bank for any draws under any Letter of Credit shall, if an
Event of Default under Section 10.01(f) occurs, be available to secure and
satisfy any of the Obligations.

Capitalization Note, at the option of the Bank.

                 (c)      Upon the date of issuance of any Letter of Credit and
on each annual anniversary thereof, the Company agrees to pay the Bank a fee in
respect of each Letter of Credit issued for the account of the Company (the

Letter of Credit to the expiry date of such Letter of Credit, computed at the
rate of (i) one-half of one percent (0.5%) per annum of the face amount of any
Letter of Credit secured by Letter of Credit Collateral and (ii) at the rate of
one percent (1%) per annum of the face amount of any Letter of Credit secured

deemed earned when paid and are non- refundable.

                 (d)      In no event shall the Fees payable under this Section
(to the extent, if any, constituting interest under applicable laws) together
with all amounts constituting interest under applicable laws and payable in
connection with this Agreement, the Notes and the other Loan Documents exceed
the Highest Lawful Rate.

                 SECTION 4.02.   Voluntary Reduction of Commitment.  Upon at
least five (5) Business Days' prior telephonic notice confirmed in writing to
the Bank, the Company shall have the right, without premium or penalty, to
terminate any portion of the Revolving Credit Commitment or the Letter of
Credit Commitment.  Any reduction of either of said commitments shall be in the
amount of $500,000.00 or, if greater, an integral multiple of $100,000.00.

                 SECTION 4.03.   Mandatory Reduction of Commitment.  Unless

has the corporate power and authority to execute, deliver and perform its
obligations hereunder and under the other Loan Documents, and all such action
has been duly authorized by all necessary proceedings on its part.  This

and constitutes a valid and legally binding agreement of such Loan Party
enforceable in accordance with its terms, and the Notes and the other Loan
Documents to which such Loan Party is a party, when duly executed and delivered

by bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
other similar laws relating to or affecting the enforcement of creditors'
rights generally, and by general principles of equity.

                 SECTION 6.03.   Governmental Consents.  No authorization,

                 SECTION 6.04.   Conflicting or Adverse Agreements or
Restrictions.  No Loan Party is a party to any contract or agreement or subject
to any restriction which would reasonably be expected to have a Material
Adverse Effect.  Neither the execution nor delivery of the Loan Documents nor
compliance with the terms and provisions hereof or thereof will be contrary to
the provisions of, or constitute a default under (a) the charter or bylaws of
such Loan Party or (b) any applicable law (including Regulation U) or any
applicable regulation, order, writ, injunction or decree of any court or
governmental instrumentality or (c) any material agreement to which such Loan
Party is a party or by which it is bound or to which it is subject.

                 SECTION 6.05.   Title to Assets.  Each Loan Party has good
and indefeasible title to all of its assets,  subject to no Liens, except those
permitted hereunder.  All of such assets have been and are being maintained by

December 31, 1994 and the results of their operations for the period then
ended.  As of the Effective Date, no Material Adverse Effect has occurred in
the consolidated financial condition of the Company and its consolidated
Subsidiaries since the date of said Financials.

                 SECTION 6.08.   Default.  Upon the execution hereof, no Loan
Party is in default under the provisions of any instrument evidencing any
Indebtedness or of any agreement relating thereto, or in default in any respect
under any order, writ, injunction or decree of any court, or in default in any
respect under or in violation of any order, injunction or decree of any
governmental instrumentality, which defaults or violations would reasonably be
expected to have a Material Adverse Effect.  No Loan Party is a party to any
material agreement evidencing any Indebtedness of such Person with an
outstanding principal amount in excess of $250,000.00 on the date of the
execution of this Agreement.

                 SECTION 6.13.   Environmental Matters.  Each Loan Party and
each of its Subsidiaries (a) possesses all environmental, health and safety
licenses, permits, authorizations, registrations, approvals and similar rights
necessary under law or otherwise for such Loan Party or such Subsidiary to

aggregate for all Loan Parties and such Subsidiaries, have a Material Adverse
Effect) and (b) each of such licenses, permits, authorizations, registrations,
approvals and similar rights is valid and subsisting, in full force and effect
and enforceable by such Loan Party or such Subsidiary, and each Loan Party and
each of its Subsidiaries is in compliance with all terms, conditions or other
provisions of such permits, authorizations, registrations, approvals and

material obligations, undertakings or liabilities arising out of or relating to
Environmental Laws to which any Loan Party or any of its Subsidiaries has
agreed, assumed or retained, or by which any Loan Party or any of its

a Material Adverse Effect.  Except as disclosed on Schedule 6.13, no Loan Party
or any of its Subsidiaries has received a written notice or claim to the effect
that such Person is or may be liable to any other Person as the result of a
Release or threatened Release of a Hazardous Material, which liability would

the Loans will be used directly or indirectly for the purpose of purchasing or
carrying any "margin stock" within the meaning of Regulation U (herein called
"margin stock") or for the purpose of reducing or retiring any indebtedness
which was originally incurred to purchase or carry a margin stock, or for any
other purpose which might constitute this transaction a "purpose" credit within
the meaning of Regulation U.  Neither any Loan Party nor any agent acting on
its behalf has taken or will take any action which might cause this Agreement
or any other Loan Document to violate Regulation U, Regulation X, or any other
regulation of the Board or to violate the Securities Exchange Act of 1934.

                 SECTION 6.15.   Franchises and Other Operating Rights.  Each

other obligations and covenants of the Company now or hereafter existing under

                                      -35-

present and continuing guaranty of payment and not of collectibility and is in
no way conditioned upon any attempt to collect from the Company or any other

without notice to or assent by such Guarantor, and that it will remain bound
upon this Guaranty notwithstanding any extension, renewal or other alteration
of any Guaranteed Obligations or Loan Documents, or any repayment and
reborrowing of Loans.  To the maximum extent permitted by applicable law, the
obligations of each Guarantor under this Guaranty shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance

         respect to, any direct or indirect security for any Guaranteed
         Obligations, including the release of any Guarantor or other Person
         liable on any Guaranteed Obligations;

                 (d)      any change in the corporate existence, structure or
         ownership of the Company, any Guarantor, or any insolvency,
         bankruptcy, reorganization or other similar proceeding affecting the
         Company, such Guarantor, any other Guarantor or any of their
         respective assets;

                 (e)      the existence of any claim, defense, set-off or other
         rights or remedies which such Guarantor at any time may have against
         the Company, or the Company or such Guarantor may have at any time
         against the Bank, any other Guarantor or any other Person, whether in
         connection with this Guaranty, the Loan Documents, the transactions
         contemplated thereby or any other transaction other than by the
         payment in full by the Company of the Guaranteed Obligations after the
         termination of the commitments of the Bank and the expiration or
         termination of all Letters of Credit;





                                      -36-
   42
                 (f)      any invalidity or unenforceability for any reason of
         this Agreement or other Loan Documents, or any provision of law
         purporting to prohibit the payment or performance by the Company, such
         Guarantor or any other Guarantor of the Guaranteed Obligations or Loan
         Documents, or of any other obligation to the Bank; or

                 (g)      any other circumstances or happening whatsoever,
         whether or not similar to any of the foregoing.

                 SECTION 9.03.   Effect of Debtor Relief Laws.  If after
receipt of any payment of, or proceeds of any security applied (or intended to
be applied) to the payment of all or any part of the Guaranteed Obligations,
the Bank is for any reason compelled to surrender or voluntarilysurrenders,
such payment or proceeds to any Person (a) because such payment or application
of proceeds is or may be avoided, invalidated, declared fraudulent, set aside,
determined to be void or voidable as a preference, fraudulent conveyance,
fraudulent transfer, impermissible set-off or a diversion of trust funds or (b)
for any other reason, including (i) any judgment, decree or order of any court
or administrative body having jurisdiction over the Bank, or any of its
properties or (ii) any settlement or compromise of any such claim effected by
the Bank with any such claimant (including the Company), then the Guaranteed
Obligations or part thereof intended to be satisfied shall be reinstated and
continue, and this Guaranty shall continue in full force as if such payment or
proceeds have not been received, notwithstanding any revocation thereof or the
cancellation of any Note or any other instrument evidencing any Guaranteed
Obligations or otherwise; and each Guarantor, jointly and severally, shall be
liable to pay the Bank, and hereby does indemnify the Bank and hold it harmless
for the amount of such payment or proceeds so surrendered and all expenses
(including reasonable attorneys' fees, court costs and expenses attributable
thereto) incurred by the Bank in the defense of any claim made against it that
any payment or proceeds received by the Bank in respect of all or part of the
Guaranteed Obligations must be surrendered.  The provisions of this paragraph
shall survive the termination of this Guaranty, and any satisfaction and
discharge of the Company by virtue of any payment, court order or any federal
or state law.

                 SECTION 9.04.   Complete Waiver of Subrogation.
Notwithstanding any payment or payments made by any Guarantor hereunder, or any
set-off or application by the Bank of any security or of any credits or claims,
no Guarantor will assert or exercise any rights of the Bank or of such
Guarantor against the Company to recover the amount of any payment made by such
Guarantor to the Bank hereunder by way of any claim, remedy or subrogation,
reimbursement, exoneration, contribution, indemnity, participation or otherwise
arising by contract, by statute, under common law or otherwise, and such
Guarantor shall not have any right of recourse to or any claim against assets
or property of the Company, whether or not the obligations of the Company
guaranteed hereby have been satisfied.  Each Guarantor hereby expressly waives
any right to exercise any claim, right or remedy which such Guarantor may now
have or hereafter acquire against the Company or any other Guarantor that
arises under this Agreement or any other Loan Document or from the performance





                                      -37-
   43
by any Guarantor of the Guaranty hereunder including any claim, remedy or right
of subrogation, reimbursement, exoneration, contribution, indemnification or
participation in any claim, right or remedy of the Bank against the Company or
any Guarantor, or any security that the Bank now has or hereafter acquires,
whether or not such claim, right or remedy arises in equity, under contract, by
statute, under common law or otherwise.  Each Guarantor agrees not to seek
contribution or indemnity or other recourse from any other Guarantor or other
Person.  If any amount shall nevertheless be paid to a Guarantor by the Company
or another Guarantor prior to payment in full of the Guaranteed Obligations,
such amount shall be held in trust for the benefit of the Bank and shall
forthwith be paid to the Bank to be credited and applied to the Guaranteed
Obligations, whether matured or unmatured.  The provisions of this paragraph
shall survive the termination of this Guaranty, and any satisfaction and
discharge of the Company by virtue of any payment, court order or any federal
or state law.

                 SECTION 9.05.   Subordination.  If any Guarantor becomes the
holder of any indebtedness payable by the Company or another Guarantor, each
Guarantor hereby subordinates all indebtedness owing to it from the Company to
all indebtedness of the Company to the Bank, and agrees that during the
continuance of any Default or Event of Default it shall not accept any payment
on the same until payment in full of the Obligations of the Company under this
Agreement and the other Loan Documents after the termination of the commitments
of the Bank and the termination or expiration of the Letters of Credit, the
Notes and all other Loan Documents, and shall in no circumstance whatsoever
attempt to set-off or reduce any obligations hereunder because of such
indebtedness.  If any amount shall nevertheless be paid to a Guarantor by the
Company or another Guarantor prior to payment in full of the Guaranteed
Obligations, such amount shall be held in trust for the benefit of the Bank and
shall forthwith be paid to the Bank to be credited and applied to the
Guaranteed Obligations, whether matured or unmatured.

                 SECTION 9.06.   Waiver.  Each Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect
to any of the Guaranteed Obligations and this Guaranty and waives presentment,
demand of payment, notice of intent to accelerate or of acceleration, notice of
dishonor or nonpayment and any requirement that the Bank institute suit,
collection proceedings or take any other action to collect the Guaranteed
Obligations, including any requirement that the Bank protect, secure, perfect
or insure any Lien against any property subject thereto or exhaust any right or
take any action against the Company or any other Person or any Collateral (it
being the intention of the Bank and each Guarantor that this Guaranty is to be
a guaranty of payment and not of collection).  It shall not be necessary for
the Bank, in order to enforce any payment by any Guarantor hereunder, to
institute suit or exhaust its rights and remedies against the Company, any
other Guarantor or any other Person, including others liable to pay any
Guaranteed Obligations, or to enforce its rights against any security ever
given to secure payment thereof.  Each Guarantor hereby expressly waives to the
maximum extent permitted by applicable law each and every right to which it may
be entitled by virtue of the suretyship laws of the State of Texas,





                                      -38-
   44
including any and all rights it may have pursuant to Rule 31, Texas Rules of
Civil Procedure, Section 17.001 of the Texas Civil Practice and Remedies Code
and Chapter 34 of the Texas Business and Commerce Code.  Each Guarantor hereby
waives marshaling of assets and liabilities, notice by the Bank of any
indebtedness or liability to which the Bank applies or may apply any amounts
received, and of the creation, advancement, increase, existence, extension,
renewal, rearrangement or modification of the Guaranteed Obligations.  Each
Guarantor expressly waives, to the extent permitted by applicable law, the
benefit of any and all laws providing for exemption of property from execution
or for valuation and appraisal upon foreclosure.

                 SECTION 9.07.   Full Force and Effect.  This Guaranty  is a
continuing guaranty and shall remain in full force and effect until all of the
Obligations of the Company under this Agreement and the other Loan Documents
and all other amounts payable under this Guaranty have been paid in full (after
the termination of the commitments of the Bank and the termination or
expiration of the Letters of Credit).  All rights, remedies and powers provided
in this Guaranty may be exercised, and all waivers contained in this Guaranty
may be enforced, only to the extent that the exercise or enforcement thereof
does not violate any provisions of applicable law which may not be waived.

Default has occurred and is continuing, the Bank may, by written notice to the
Company (a "Notice of Default") take any or all of the following actions,
without prejudice to the rights of the Bank or other holder of any of the
Obligations to enforce its claims against any Loan Party (provided that, if an
Event of Default specified in Section 10.01(e) or Section 10.01(f) shall occur
with respect to any Loan Party, the following shall occur automatically without
the giving of any Notice of Default):  (i) declare the Bank's Revolving Credit
Commitment and the Letter of Credit Commitment terminated; (ii) declare the
principal of and any accrued and unpaid interest in respect of all Loans, and
all obligations owing hereunder, to be, whereupon the same shall become,

exercise of





                                      -41-
   47
any power granted in this Agreement or in any other Loan Document; or may
proceed to realize on any collateral securing the Loans or to enforce the
payment of all amounts owing to the Bank under the Loan Documents and any

it being intended that no remedy conferred herein or in any of the other Loan

of the Bank to exercise, and no delay in exercising, any right hereunder, under
any Note or under any other Loan Document shall operate as a waiver thereof;
nor shall any single or partial exercise of any such right, or any abandonment
or discontinuance of any steps to enforce such right, preclude any other or
further exercise thereof or the exercise of any other right.  No notice to or
demand on the Company in any case shall entitle the Company to any other or
further notice or demand in similar or other circumstances.  The remedies
herein provided are cumulative and not exclusive of any remedies provided by
law.

                 SECTION 11.04.   Costs, Expenses and Taxes.  The Company
agrees to pay on demand:  (a) all reasonable out-of-pocket costs and expenses
of the Bank in connection with the preparation, execution, delivery,

Agreement, any Note or any other Loan Document.  Without prejudice to the

   49
                 SECTION 11.05.   Indemnity and Release.  (a) The Loan Parties
jointly and severally indemnify the Bank and each Affiliate thereof and their
respective directors, officers, employees and agents from, and hold each of
them harmless against, any and all losses, liabilities, claims or damages
(including reasonable legal fees and expenses) to which any of them may become
subject, insofar as such losses, liabilities, claims or damages arise out of or
result from (i) any actual or proposed use by the Company of the proceeds of
any extension of credit by any Bank hereunder or (ii) any investigation,
litigation or other proceeding (including any threatened investigation or
proceeding) relating to the foregoing or any of the other Loan Documents, and
the Loan Parties jointly and severally shall reimburse the Bank and each
Affiliate thereof and their respective directors, officers, employees and
agents, upon demand for any expenses (including legal fees) reasonably incurred
in connection with any such investigation or proceeding; but excluding any such
losses, liabilities, claims, damages or expenses incurred by reason of the
gross negligence or willful misconduct of the Person to be indemnified.

                 (b)      WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT, IT
IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE
INDEMNIFIED HEREUNDER OR THEREUNDER SHALL BE INDEMNIFIED AND HELD HARMLESS
AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISING OUT OF OR
RESULTING FROM THE ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH PERSON.
Without prejudice to the survival of any other obligations of the Loan Parties
hereunder and under the other Loan Documents, the obligations of the Loan
Parties under this Section shall survive the termination of this Agreement and
the other Loan Documents and the payment of the Obligations or the assignment
of the Notes.

                 (c)      The Loan Parties do hereby release and forever
discharge the Bank and each Affiliate thereof and their respective employees,
officers, directors, trustees, agents, successors, assigns or other
representatives from any and all claims (civil or criminal), demands, damages,
actions, cross-actions, causes of action, costs and expenses (including legal
expenses), of any kind or nature whatsoever, which any Loan Party has held or
may now or in the future own or hold, whether known or unknown, for or because
of any matter or thing done, omitted or suffered to be done on or before the
Execution Date hereof by any of such parties (i) arising directly or indirectly
out of the Loan Documents or any other documents, instruments or any other
transactions relating thereto and/or (ii) relating directly or indirectly to
all transactions by and between the Loan Parties and the Bank.  Such release,
waiver, acquittal and discharge shall and does include, without limitation, any
claims of usury which may or could be asserted by the Loan Parties.  This
release shall not include a release of the Bank from any claim by the Loan
Parties for breach by the Bank of this Agreement.

                 SECTION 11.06.   Right of Setoff.  If any Event of Default
shall have occurred and be continuing, the Bank is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (time or demand, provisional or final) at





                                      -44-
   50
any time held and other indebtedness at any time owing by the Bank, or any
branch, subsidiary or Affiliate, to or for the credit or the account of any
Loan Party against any and all the Obligations of the Loan Parties now or
hereafter existing under this Agreement and the other Loan Documents and other
obligations of the Loan Parties held by the Bank, irrespective of whether or
not the Bank shall have made any demand under this Agreement, such Note, the
Obligations or such other obligations and although the Obligations or such
other obligations may be unmatured.  The Bank agrees promptly to notify the
Company after any such setoff and application, but the failure to give such
notice shall not affect the validity of such setoff and application.  The
rights of the Bank under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Bank may have.

                 SECTION 11.07.   Governing Law.  This Agreement, all Notes,
the other Loan Documents and all other documents executed in connection
herewith and therewith, shall be deemed to be contracts and agreements executed
by the Loan Parties, the Bank under the laws of the State of Texas and of the
United States of America and for all purposes shall be construed in accordance
with, and governed by, the laws of said state and of the United States of
America.  Without limitation of the foregoing, nothing in this Agreement, or in
the Notes or in any other Loan Document shall be deemed to constitute a waiver
of any rights which any Bank may have under applicable federal legislation
relating to the amount of interest which such Bank may contract for, take,
receive or charge in respect of any Loans or other Obligations to such Bank
hereunder and under the other Loan Documents, including any right to take,
receive, reserve and charge interest at the rate allowed by the law of the
state where such Bank is located.  The Bank and the Loan Parties further agree
that insofar as the provisions of Article 1.04, Subtitle 1, Title 79, of the
Revised Civil Statutes of Texas, 1925, as amended, are applicable to the
determination of the Highest Lawful Rate with respect to the Notes and the
Obligations hereunder and under the other Loan Documents, the indicated rate
ceiling computed from time to time pursuant to Section (a)(1) and Section (b)
of such Article shall be applicable; provided, however, that to the extent
permitted by such Article, the Bank may from time to time by notice from the
Bank to the Company revise the election of such interest rate ceiling as such
ceiling affects the then current or future balances of the Loans outstanding
under the Notes and the Obligations hereunder and under the other Loan
Documents.  The provisions of Chapter 15 of Subtitle 3 of the said Title 79 do
not apply to this Agreement, any Note issued hereunder or the Obligations
hereunder and under the other Loan Documents.

                 SECTION 11.08.   Maximum Interest.  Each provision in this
Agreement and each other Loan Document is expressly limited so that in no event
whatsoever shall the amount paid, or otherwise agreed to be paid, to the Bank,
or charged, contracted for, reserved, taken or received by the Bank, for the
use, forbearance or detention of the money to be loaned under this Agreement or
any Loan Document or otherwise (including any sums paid as required by any
covenant or obligation contained herein or in any other Loan Document which is
for the use, forbearance or detention of such money), exceed that amount of
money which would cause the effective rate of interest to exceed





                                      -45-
   51
the Highest Lawful Rate, and all amounts owed under this Agreement and each
other Loan Document shall be held to be subject to reduction to the effect that
such amounts so paid or agreed to be paid, charged, contracted for, reserved,
taken or received which are for the use, forbearance or detention of money under
this Agreement or such Loan Document shall in no event exceed that amount of
money which would cause the effective rate of interest to exceed the Highest
Lawful Rate.  Anything in any Note or any other Loan Document to the contrary
notwithstanding, the Company shall not be required to pay unearned interest on
any Note and no Loan Party shall be required to pay interest on its Obligations
hereunder and under the Loan Documents to which it is a party at a rate in
excess of the Highest Lawful Rate, and if the effective rate of interest which
would otherwise be payable under such Note, such Obligations and such Loan
Documents would exceed the Highest Lawful Rate, or if the holder of such Note or
such Obligations shall receive any unearned interest or shall receive monies
that are deemed to constitute interest which would increase the effective rate
of interest payable by the Company under such Note and the Loan Parties under
such Obligations and the Loan Documents to which it is a party to a rate in
excess of the Highest Lawful Rate, then (a) the amount of interest which would
otherwise be payable by such Loan Party under such Obligations and such Loan
Documents shall be reduced to the amount allowed under applicable law and (b)
any unearned interest paid by such Loan Party or any interest paid by such
Loan Party in excess of the Highest Lawful Rate shall in the first instance be
credited on the principal of the Obligations of such Loan Party (or if all such
Obligations shall have been paid in full, refunded to the Loan Party paying such
unearned interest).  It is further agreed that, without limitation of the
foregoing, all calculations of the rate of interest contracted for, charged or
received by the Bank in respect of the Obligations shall be made, to the extent
permitted by law by amortizing, prorating and spreading in equal parts during
the period of the full stated term of all of  the Loans and the other
Obligations, all interest at any time contracted for, charged or received by the
Bank.

                 SECTION 11.09.   Survival of Representations and Warranties.
All representations, warranties and covenants contained herein or made in
writing by the Loan Parties in connection herewith and the other Loan Documents
shall survive the execution and delivery of this Agreement, the Notes and the
other Loan Documents until two years and one day after payment in full of the
Obligations, the termination of the commitments of the Bank and the termination
or expiration of the Letters of Credit, and will bind and inure to the benefit
of the respective successors and assigns of the parties hereto, whether so
expressed or not, provided, that the Revolving Credit Commitment and the Letter
of Credit Commitment of the Bank shall not inure to the benefit of any
successor or assign of the Company.

                 SECTION 11.10.   Binding Effect.  This Agreement shall become
effective when it shall have been executed by the Loan Parties and the Bank and
shall inure to the benefit of the Loan Parties, Bank and their respective
permitted successors and assigns.





                                      -46-
   52
                 SECTION 11.11.   Successors and Assigns; Participations.  The
Loan Parties may not assign or transfer any of their rights or obligations
hereunder without the written consent of the Bank.  The Bank may, without the
consent of any Loan Party, assign to or sell participations to one or more
banks in all or a portion of its rights and obligations under this Agreement
and the other Loan Documents.

                 SECTION 11.12.   Types of Loans.  Loans hereunder are
distinguished by "Type" and by "Purpose".  The Type of a Loan refers to whether
such Loan is a Eurodollar Rate Loan or an Alternate Base Rate Loan, the Purpose
of a Loan refers to whether it is a Revolving Credit Loan, Term Loan or Letter
of Credit Loan.

$2,000,000.00                                                      June 30, 1995


               FOR VALUE RECEIVED, the undersigned, AMERICAN ECOLOGY
CORPORATION, a Delaware  corporation ("Maker"), promises to pay to the order
of TEXAS COMMERCE BANK NATIONAL ASSOCIATION, a national banking association
("Payee"), at 712 Main Street, Houston, Texas 77002, or such other place as the
Payee may designate from time to time in writing, in lawful money of the United
States of America, the principal sum of TWO MILLION AND NO/100 DOLLARS
($2,000,000.00), together with interest on said principal, or so much thereof
as may be from time to time outstanding, at a rate per annum equal to the
lesser of: (i) the Prime Rate plus one percent per annum and (ii) the maximum,
non-usurious rate of interest (the "Highest Lawful Rate") permitted by the
applicable laws of the State of Texas or the United States of America,
whichever shall permit the higher lawful rate and as to which Maker could not
successfully assert a claim or defense of usury, and to the extent that the
Highest Lawful Rate is determined by reference to the laws of the State of
Texas, the Highest Lawful Rate shall be the indicated (weekly) rate ceiling (as
defined and described in Texas Revised Civil Statutes, Article 5069-1.04, as

under the Credit Agreement (hereinafter defined), interest on the outstanding
principal balance of this Note shall accure at the Highest Lawful Rate.  The
"Prime Rate" means, for any day, a fluctuating rate per annum as shall be in

the prime rate most recently determined by Payee and thereafter entered in the
minutes of Payee's Loan and Discount Committee, automatically fluctuating
upward and downward with and at the times specified in each such determination
without notice to Makers or any other person, which prime rate may not
necessarily represent the lowest or best rate actually charged to a customer.
As of the date hereof, the outstanding principal balance owing under this Note
is ONE MILLION AND NO/100 DOLLARS ($1,000,000.00); provided, such outstanding
principal balance is subject to increase pursuant to the terms of the Credit
Agreement (hereinafter defined).

               This Note shall be payable as follows:  Interest due hereunder
shall be payable monthly as it accrues on the 1st day of each month.  All
principal due hereunder shall be due and payable on the Maturity Date, as
defined in that one certain Credit Agreement of even date herewith between
Maker, as borrower, and the Payee, as Bank, concerning the extension of certain
loans by Payee to Maker (the "Credit Agreement");  provided, the Payee may, at
any time in its sole and absolute discretion, in lieu of accepting payment in
cash, require a principal payment or prepayment hereunder to be made in the
common stock of the Company (the "Common Stock") currently trading


                                                           Initial for ID
                                                                         ------
   63
on the Nasdaq National Market, in the amount of the number of shares of Common
Stock equal to the quotient of the outstanding principal balance to be paid or
prepaid under this Note on the such payment date divided by $4.75.  In the
event Maker recapitalizes, reclassified its capital stock, merges with or into
or consolidates with any other corporation, sells or transfers substantially
all of its assets or otherwise changes its capital structure in such a way that
the Common Stock is converted into the right to receive stock, securities or
other property, then Payee may, in its sole and absolute discretion, require
payment hereof to be made in such stock, securities or other property that
Payee would have been entitled to receive had Payee owned the number of shares
of Common Stock equal to the quotient of the outstanding principal balance
owing under this Note immediately prior to such recapitalization,
reclassification, merger, consolidation, sale, transfer or other change in
capital structure divided by $4.75.  Notwithstanding anything contained in the
Credit Agreement, this Note may not be prepaid without the express written
consent of Payee.

               This Note is the Fee Capitalization Note referred to in, and is
entitled to the benefits of, the Credit Agreement.  This Note evidences the
obligations of the Company in respect of: (i) the unpaid fees due and owing
under Sections 4.01(a) and (c) of the Credit Agreement; (ii) the option
exercised by the Company to reduce the interest rate owing on the Term Loan,
which amount is also unpaid; and (iii) any accrued, unpaid interest due under
the terms of the Credit Agreement but capitalized as provided therein and
included as principal hereunder.  The obligations of the Company hereunder are
guaranteed by the guaranty agreements contained in the Credit Agreement.  The
Credit Agreement, among other things (i) provides for the making of Loans by
the Bank to the Company, certain of the Indebtedness of the Company to the Bank
being evidenced by this Note, (ii) contains provisions for acceleration of the
maturity hereof upon the happening of certain stated events, (iii) describes

for the limitation on the amount of interest to be paid such that no term of
the Credit Agreement or this Note shall require the payment or permit the
collection of interest in excess of the Highest Lawful Rate.

transaction, but rather that this Note evidences obligations of the Company as
described in the Credit Agreement and constitutes consideration for the waiver
by Payee of the requirements contained therein and (ii) no funds have been
advanced by Payee under this Fee Capitalization Note but that it is an element
of the Obligations of the Company under the Credit Agreement and documentary
evidence of the Company's duty to make payment in respect of its Obligations
thereunder.

severally waive grace, demand, presentment for payment, notice of dishonor or

collecting and bringing of suit against any party hereto, and agree to all
renewals, extensions or partial payments hereon and to any release or
substitution of security herefor, in whole or in part, with or without notice,
