ITEM 5.  OTHER EVENTS.

       On December 31, 1996, American Ecology Corporation (the "Company") and
its subsidiaries as guarantors, entered into a Third Amended Credit Agreement
(the "Agreement") with Texas Commerce Bank National Association (the "Bank"),
amending and restating the Company's existing secured debt agreement.

       The new loan terms extend the maturity date of the Company's existing
debt to December 31, 2000.  Interest at the rate of 7% will accrue on the debt
and be added to the principal balance through December 1998.  Thereafter,
interest will be paid quarterly at the greater of 10% or prime.  Repayment of
principal commences with a $5.0 million payment due December 31, 1999, and
$250,000 quarterly payments thereafter.  The Bank receives warrants,
exercisable only upon maturity of the loan, or a monetary default, to purchase
up to 10% of the Company's then outstanding common stock at a price of $1.50
per share.  The warrants are eliminated when the Company pays the difference
between the 7% accrued interest and the greater interest rate of 10% or prime
for the period of October 31, 1996 to December 31, 1998, at loan maturity.  The
financial covenants were also amended, and the Bank agreed to permit the Company
to use certain capital freed up by the restructuring as working capital.  The
Company is prohibited from paying dividends on its common stock until the debt
is fully paid.

       As a condition to the Agreement, the Company was required to raise $3.0
million in additional equity on or before December 31, 1996 which it
accomplished on November 15, 1996 through the issuance of a new Series E
Redeemable Convertible Preferred Stock to two of its directors.  That
transaction was previously reported on SEC Form 8-K dated November 27, 1996.
Additionally, the Agreement requires the Company use its best efforts to raise
an additional $2.0 million in equity capital on or before June 30, 1997.  The
Agreement is effective as of October 31, 1996.

       The Agreement is attached hereto and incorporated herein as an exhibit.

have determined in good faith that any law, rule, regulation or guideline

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

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 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.

right to such setoff under this Section 3.03 (including, in each case, interest
owing thereon) shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Company may have or have had against the Bank, including any

consistently applied (except as otherwise disclosed in such financial
statements) throughout the periods involved and present fairly, in all material
respects, the consolidated financial position of the Company and its
consolidated Subsidiaries as of December 31, 1995 and the results of their

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;

              (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 voluntarily surrenders, 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),





                                       52
<PAGE>   47
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.   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, unless and until, the Obligations of the Company
guaranteed hereby have been fully and finally satisfied.  Until such time, 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 (but not any other Guarantor) that arises under this Agreement or any
other Loan Document or from the performance 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 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.  If any
amount shall be paid to a Guarantor by the Company or another Guarantor after
payment in full of the Obligations, and the Obligations shall thereafter be
reinstated in whole or in part and the Bank forced to repay and sums received
by any of them in payment of the Obligations, this Guaranty shall be
automatically reinstated and 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, provided such provisions shall not apply to ALEX.

              SECTION  9.05.   Subordination.  If any Guarantor becomes the
holder of any indebtedness payable by the Company or another Guarantor
(including, without limitation, by way of subrogation or contribution right),
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.  The provisions of this
Section 9.05 shall not apply to ALEX.

              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. To the extent any such may be applicable, 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, 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.

the other Loan Documents and the exercise of the Bank's rights under this
Agreement, the Notes, the Letters of Credit and the other Loan Documents or
otherwise and any actual or proposed use by the Company of the proceeds of any
extension of credit by the 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 Indemnified Parties upon
demand for  any damages, costs and expenses by any of the Indemnified Parties
in investigating, preparing for, defending against, or providing evidence,
producing documents, or taking any other action in respect of 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 Indemnified Party 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

omitted or suffered to be done on or before the actual date upon which this
Agreement is signed by any of such parties (i) arising directly or indirectly
out of the loan documents, any of the prior 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

any claim by the Loan Parties for breach by the Bank of this Agreement or the
Agreement Regarding Escrow Account dated October 30, 1996.

              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 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

HEREOF OR THEREOF), SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

              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, charged,
contracted for, reserved, taken or received by the Company for the use,
forbearance or detention of the money to be loaned under this Agreement or any
other 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 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.  To the extent that the Highest Lawful Rate applicable to the Bank is at
any time determined by Texas law, such rate shall be the "indicated rate
ceiling" described in Section (a)(1) of Article 1.04 of Chapter 1, Subtitle 1,
Title 79, of the Revised Civil Statutes of Texas, 1925, as amended; provided,
to the extent permitted by such Article, the Bank from time to time by notice
to Company may revise the aforesaid election of such interest rate ceiling as
such ceiling affects the then-current or future balances of the Loans
outstanding under the Notes.  Notwithstanding any provision in this Agreement
or any other Loan Document to the contrary, if the maturity of the Notes  or
the obligations in respect of the other Loan Documents are accelerated for any
reason, or in the event of prepayment of all or any portion of the Notes  or
the obligations in respect of the other Loan Documents by the Company or in any
other event, earned interest on the Loans and such other obligations of the
Company may never exceed the maximum amount permitted by applicable law, and
any unearned interest otherwise payable under the Notes or the obligations in
respect of the other Loan Documents that is in excess of the maximum amount
permitted by applicable law shall be cancelled automatically as of the date of
such acceleration or prepayment or other such event and, if theretofore paid,
shall be credited on the principal of the Notes or, if the principal of the
Notes has been paid in full, held as collateral for any contingent or unmatured
obligation of the Company, or, if there are no contingent or unmatured
obligations of the Company then outstanding, refunded to the Company.  In
determining whether or not the interest paid or payable, under any specific
contingency, exceeds the Highest Lawful Rate, the Company and the Bank shall,
to the maximum extent permitted by applicable law, amortize, prorate, allocate
and spread, in equal parts during the period of the actual term of this
Agreement, all





                                       62

interest at any time contracted for, charged, received or reserved in
connection with this Agreement.

              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 any reimbursement obligations with
respect thereto, 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.

              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.   Intentionally Deleted.

              SECTION  11.13.   Accounting Terms.  All accounting terms not
otherwise defined herein shall be construed in accordance with GAAP.

              SECTION  11.14.   Independence of Covenants.  All covenants
contained in this Agreement and in the other Loan Documents shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that such action or condition would be
permitted by an exception to, or otherwise be within the limitations of,
another covenant, shall not avoid the occurrence of a Default or an Event of
Default if such action is taken or condition exists.

              SECTION  11.15.   Separability.  Should any clause, sentence,
paragraph or Section of this Agreement be





                                       63
<PAGE>   58
judicially declared to be invalid, unenforceable or void, such decision will
not have the effect of invalidating or voiding the remainder of this Agreement,
and the parties hereto agree that the part or parts of this Agreement so held
to be invalid, unenforceable or void will be deemed to have been stricken
herefrom and the remainder will have the same force and effectiveness as if
such part or parts had never been included herein.

              SECTION  11.16.   Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

              SECTION  11.17.   Interpretation.  (a) In this Agreement, unless

              SECTION  11.18.   Submission to Jurisdiction.

              (a)    Each Loan Party hereby irrevocably submits to the non-
exclusive jurisdiction of any New York state court located in the Borough of
Manhattan, City and State of New York, or any federal court located in the
Southern District of New York over any action or proceeding arising out of or
relating to this Agreement or any of the other Loan Documents, and each of the
Loan Parties irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in such New York state or federal court;
provided, nothing in this Section 11.18 is intended to waive the right of the
Bank to remove any such action or proceeding commenced in any such New York
state court to an appropriate New York federal court to the extent the basis
for such removal exists under applicable law.  Each Loan Party hereby
irrevocably appoints CT Corporation  (the "Process Agent"), with an office on

receive on behalf of it and its properties service of copies of the summons and
complaint and any other process which may be served in any such action or
proceeding.  Such service may be made by mailing by certified mail a copy of
such process to such Loan Party in care of the Process Agent at the Process
Agent's above address, with a copy to such Person at its address specified

the Process Agent to accept such service on its behalf.  As an alternative
method of service, each of the Loan Parties also irrevocably consents to the
service of any and all process in any such action or proceeding by the mailing
by certified mail of copies of such process to it at its address specified
herein.  Each

be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law.

              (b)    Nothing in this Section 11.18 shall affect the right of
the Bank to serve legal process in any other manner permitted by law or affect
the right of the Bank to bring any action or proceeding against any of the Loan
Parties, or such Person's properties, in the courts of any other jurisdiction.

              SECTION  11.19.   Waiver of Jury Trial.  EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT TO A TRIAL
BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS
