Item 2.  Acquisition or Disposition of Assets.

      On January 15, 1999, the Company acquired Romic Environmental Technologies
Corporation, a California corporation ("Romic Environmental"), in exchange for
approximately $27.3 million in cash and 284,101 shares of common stock, par
value $.01, of the Company. These transactions were consummated pursuant to a
Stock Purchase Agreement between the Company, Romic Environmental and the former
shareholders of Romic Environmental.

      Romic Environmental provides distillation, fuel blending and similar
services to generators of hazardous and nonhazardous liquid waste. In addition,
Romic Environmental recycles spent solvents, anti-freeze and other wastes
generated by automotive maintenance and repair facilities. The Company currently
intends to operate Romic Environmental in substantially the same manner as it
was operated prior to this transaction. The Company funded the cash portion of
the purchase price paid for Romic Environmental with borrowings under the
Company's revolving credit facility with Bank of America National Trust and
Savings Association, BankBoston, N.A., Wells Fargo Bank, N.A., Bank Paribas,
Comerica Bank and Union Bank of California. The purchase price was determined
based upon an evaluation of the business of Romic Environmental and the results
of negotiations between the parties.

agreements contained herein, the parties hereto agree as follows:

                                  ARTICLE 1

                         PURCHASE AND SALE OF SHARES

conditions hereof, the Sellers shall sell, transfer, convey and assign to

                                  ARTICLE 2

                                PURCHASE PRICE

     2.1 PURCHASE PRICE. Subject to the terms set forth in this Agreement, and
in consideration of the sale and delivery to Purchaser of the certificates
representing the Shares, Purchaser shall deliver to the Sellers on the Closing
Date (or with respect to the U S Liquid Shares (as defined below), within a
reasonable time following the Closing Date), an aggregate of Thirty-Four Million
One Hundred Fifty-One Thousand Twelve Dollars ($34,151,012) consisting of: (a)
immediately available funds in an amount determined by subtracting from
Thirty-Four Million One Hundred Fifty-One Thousand Twelve Dollars ($34,151,012)
the amounts to be transferred or assumed, as the case may be, pursuant to
subparagraphs (b), (c) and (d) hereof; (b) that total number of shares of the
common stock of Purchaser, par value one cent ($.01) per share (the "U S Liquids

total number of U S Liquids Common Stock which shall have an Agreed Value of Two
Million Two Hundred Fifty Thousand Dollars ($2,250,000), all of which will be

Article 11 hereof (collectively, the "U S Liquids Shares"); and (d) assumption

on Annex I attached hereto and made a part hereof.

                                       2
<PAGE>
     2.2 AGREED VALUE OF U S LIQUIDS COMMON STOCK. For purposes of this
Agreement, the "Agreed Value" per share of the U S Liquids Common Stock shall be
the closing price of a share of such stock of Purchaser on the American Stock
Exchange the day before the Closing Date, as reported in the WALL STREET
JOURNAL.

     2.3 ASSUMPTION OF DEBT. As a portion of the Purchase Price payable in
Section 2.1 above, at Closing, Purchaser shall assume the obligations of the
Corporation, as set forth in Schedule 2.3, and repay, at Closing or as soon
thereafter as is practicable, the indebtedness of the Corporation set forth in
Schedule 2.3. Such payment of indebtedness by Purchaser shall result in a
reduction in the cash payment to Seller required under Section 2.1(a).

     2.4    ADJUSTMENT TO CONSIDERATION.

               (a) The parties agree that the consideration set forth in Section
2.1 was determined as if the net working capital of the Corporation according to
the June 30, 1998 Balance Sheet was One Million Five Hundred Ten Thousand Four
Hundred Thirty-Four Dollars ($1,510,434) at the close of business on the
Effective Date. Accordingly, the parties agree that the consideration set forth
in Section 2.1(a) shall be adjusted on the Adjustment Date to reflect the actual
net working capital of the Corporation on the Effective Date (the "Actual Net
Working Capital"), as shown on the balance sheet to be prepared in the manner
described in subparagraph (b) below. If the Actual Net Working Capital so
reflected is greater than One Million Five Hundred Ten Thousand Four Hundred
Thirty-Four Dollars ($1,510,434) on the Effective Date, then the consideration
paid pursuant to Section 2.1(a) shall be increased dollar for dollar for each
dollar the Actual Net Working Capital of the Corporation exceeds One Million
Five Hundred Ten Thousand Four Hundred Thirty-Four Dollars ($1,510,434) on the
Effective Date. If the Actual Net Working Capital so reflected is less than One
Million Five Hundred Ten Thousand Four Hundred Thirty-Four Dollars ($1,510,434)
on the Effective Date, then the consideration paid pursuant to Section 2.1(a)
shall be decreased dollar for dollar for each dollar the Actual Net Working
Capital falls below One Million Five Hundred Ten Thousand Four Hundred
Thirty-Four Dollars ($1,510,434) on the Effective Date. For purposes of this
Agreement, Actual Net Working Capital shall mean the current assets of the
Corporation on the Effective Date minus all current liabilities of the
Corporation on the Effective Date. Actual Net Working Capital shall be
calculated in accordance with generally accepted accounting principles ("GAAP"),
except that the same method of accounting used by the Corporation on its June
30, 1998 Balance Sheet to account for its (i) off-site disposal sites, (ii)
solvents inventory held for resale, and (iii) environmental liabilities relating
to the sites listed on Schedule 12.1(c) shall be used in calculating Actual Net
Working Capital.

               (b) On the date which is no more than one hundred twenty (120)
after the Closing Date (the "Adjustment Date"), Purchaser shall notify the
Sellers of any adjustment in the Purchase Price in accordance with this Section
2.4 based on the balance sheet of the Corporation as of the close of business on
the Effective Date, prepared by Purchaser in accordance with GAAP and delivered
to the Sellers, together with reasonable supporting documentation for all
current assets and liabilities used to prepare such balance sheet, at least
seven (7) days prior to the Adjustment Date.

               (c) In the event of a dispute between the parties as to the
Actual Net Working Capital, the parties will have thirty (30) days to resolve
the dispute among themselves. If the parties have not resolved such dispute
within such thirty (30) day period, then the parties shall select an arbitrator
who shall decide the dispute within thirty (30) days after being selected. If
the parties cannot agree on an arbitrator, then Purchaser (on the one hand) and
the Controlling Shareholders (on the other hand), shall each select an
arbitrator and the two (2) arbitrators so selected shall select a third
arbitrator. The parties hereto each agree to be bound by the decision of the
arbitrator(s). In the event that three (3) arbitrators are chosen, a majority
decision will be required. Each arbitrator can be any natural person above the
age of 18 and need not have any specific qualification. All costs of the
arbitration shall be split 50/50 between Purchaser and each of the Sellers (as a
group).

     2.5 EFFECTIVE DATE. The parties agree that notwithstanding the actual
Closing Date, the transactions contemplated hereunder shall be effective on and
as of the Effective Date for accounting purposes, and that all revenues, income
and losses of the Corporation shall be accounted for as if the Purchaser was the
owner of all of the stock of the Corporation on the Effective Date. Purchaser
shall indemnify Sellers for the net cost of any additional income tax imposed on
the Sellers as a result of such accounting treatment.

Company (the "Title Company") in an aggregate amount mutually acceptable to
Purchaser and the Sellers insuring title to the Leased Land and Owned Land in
the Corporation, subject only to the exceptions described herein (the "Title
Policies"). Not less than fourteen (14) days prior to the Closing Date, the
Sellers shall deliver to Purchaser preliminary title commitments in respect of
the Leased Land and Owned Land, together with copies of all exception
instruments referenced therein, and any unrecorded leases, option agreements,
contracts and any other items affecting title which are in the possession of, or

Corporation in the Owned Land to be free and clear of all encumbrances
whatsoever except: (a) zoning ordinances and regulations which do not, in
Purchaser's reasonable judgment, adversely affect continued use of the Leased
Land and Owned Land for its current uses after the Closing; (b) real estate
taxes and assessments, both general and special, which are a lien but are not
yet due and payable at the Closing Date; and (c) easements, encumbrances,
covenants, conditions, reservations and restrictions of record, if any, as have
been approved in writing by Purchaser. Purchaser shall pay all of the costs
associated with the delivery of the Title Policies.

neighboring property or on any property which is subject to any easement or
right-of-way; (f) all building lines established in respect of the Owned Land;
and (g) all public access to the Owned Land, and representing that the
boundaries of the Owned Land are contiguous with the boundaries of all adjoining
parcels (together, the "Survey"). A copy of the Survey complying with the above
requirements shall be delivered to Purchaser and the Title Company, together
with certification to each entity by the surveyor and with such additional
supporting reports and other certificates as the Title Company may require to
enable the Title Company to delete its standard survey exceptions from the Title
Policies. Purchaser shall pay all of the costs of the Survey.

                               INDEMNIFICATION

     12.1   INDEMNIFICATION.

            (a) The Controlling Shareholders agree, jointly and severally, to
indemnify and hold Purchaser and its Affiliates harmless from and against the
aggregate of all expenses, losses, costs, deficiencies, liabilities and damages
(including, without limitation, related counsel and paralegal fees and expenses)
incurred or suffered by Purchaser, or, as described in Section 12.1(d) hereof,
incurred or suffered by the Corporation (collectively, "Indemnifiable Damages")
resulting from or arising out of: (i) any breach of a representation or warranty
made by the Sellers, the Controlling Shareholders or the Corporation pursuant to
this Agreement; (ii) any breach of the covenants or agreements made by the
Sellers, the Controlling Shareholders or the Corporation in this Agreement;
(iii) any inaccuracy in any certificate delivered by the Sellers, the
Controlling Shareholders or the Corporation pursuant to this Agreement; (iv) any
misrepresentation or omission from any Schedule to this Agreement; (v) any
liability of the Sellers or the Corporation to creditors of the Sellers or the
Corporation which Purchaser has not explicitly assumed or permitted to exist
hereunder after the Closing Date, whether as a result of bankruptcy or similar
proceedings and whether as an account payable by the Sellers or the Corporation
or as a claim of alleged fraudulent conveyance or preferential payments within
the meaning of the United States Bankruptcy Code; (vi) the existence of
creditors of the Sellers or the Corporation which are not disclosed to
Purchaser; or (vii) any violation by the Controlling Shareholders or the
Corporation of the requirements of any governmental authority relating to the
reporting and payment of federal, state, local or other income, sales, use,
franchise, excise, property or other tax liabilities of the Corporation, which
occurs or exists prior to the Closing Date. The indemnity obligation contained
in this Section 12.1(a) shall continue for a period of three (3) years from and
after the Closing Date; PROVIDED, HOWEVER, that the indemnity obligations
hereunder shall continue until the fifth anniversary of the Closing Date with
respect to any claim arising from or relating to matters for which Purchaser
shall have discovered facts to establish the existence of the type of claims
described in (i) through (vii) of this Section 12.1(a) and provided notice to
the Controlling Shareholders of Purchaser's intent to seek indemnification for
such claims prior to the expiration of such three (3) year period. Purchaser
shall not be entitled to assert any claim for indemnification under this Section
12.1(a) unless and until such time as the total amount of all claims of
Purchaser for indemnification under this Section 12.1(a) in the aggregate exceed
Fifty Thousand Dollars ($50,000). Further, the Controlling Shareholders shall
not be liable under this subsection for aggregate Indemnifiable Damages in
excess of the aggregate value of all

                                       33
<PAGE>
consideration received by the Controlling Shareholders under this Agreement.

            (b) The Controlling Shareholders agree, jointly and severally, to
indemnify and hold Purchaser and its Affiliates harmless from and against the
aggregate of all Indemnifiable Damages (including those described in Section
12.1(d) hereof), resulting from or arising out of: (i) any occurrence or
circumstance (whether known or unknown) which occurs or exists on or prior to
the Closing Date and which constitutes, or which by the lapse of time or giving
notice (or both) would constitute, a breach or default by the Corporation under
any lease, Contract or other instrument or agreement whether written or oral; or
(ii) any injury to or death of any person or damage to or destruction of any
property which occurs or exists prior to the Closing Date, whether based on
negligence, breach of warranty, or any other theory, which injury, death, damage
or destruction is attributable to or caused by the Corporation or of any
stockholder, officer, director, employee or agent of the Corporation or which
occurred during, in connection with or incidental to the conduct of the
Business; PROVIDED, HOWEVER, that any such injury, death, damage or destruction
attributable to or caused by events or occurrences for which indemnity is
required pursuant to Section 12.1(c) below shall be excluded from the indemnity
obligation contained in this Section 12.1(b). The indemnity obligation contained
in this Section 12.1(b) shall continue for a period of two (2) years from and
after the Closing Date. Notwithstanding the foregoing time limitation, the
obligation of the Controlling Shareholders to indemnify Purchaser hereunder
shall continue indefinitely with respect to any claim arising from or relating
to matters for which Purchaser shall have received a formal demand or claim from
a third party and provided notice thereof to the Controlling Shareholders and of
Purchaser's intent to seek indemnification for such claims hereunder within two
(2) years of the Closing Date. Purchaser shall not be entitled to assert any
claim for indemnification under this Section 12.1(b) unless and until such time
as the amount of all claims of Purchaser for indemnification under this Section
12.1(b) exceeds Fifty Thousand Dollars ($50,000) in the aggregate, at which time
any and all claims of Purchaser for indemnification in excess of Fifty Thousand
Dollars ($50,000) may be asserted; PROVIDED, HOWEVER, that the Controlling
Shareholders shall not be liable under this Section 12.1(b) for aggregate
Indemnifiable Damages in excess of Five Hundred Thousand Dollars ($500,000) or
any matter described in part 1 of Schedule 6.10; PROVIDED, HOWEVER, that in no
event shall any schedules which are cross-referenced in any such Schedule be
excluded from such indemnity obligations.

            (c) The Controlling Shareholders agree, jointly and severally, to
indemnify and hold Purchaser and its Affiliates harmless from and against the
aggregate of all Indemnifiable Damages (including those described in Section
12.1(d) hereof), resulting from or arising out of: (i) the generation,
collection, transportation, storage or disposal, by the Corporation or during,
in connection with or incidental to the conduct of the Business prior to the
Closing Date, of any materials, including, without limitation, hazardous
materials; or (ii) any act or omission by the Corporation or any stockholder,
officer, director, employee or agent of the Corporation prior to the Closing
Date which causes or contributes to a release of any materials, pollutants,
heat, smoke, fire, odors, or fumes into the environment (including air, surface
water and groundwater and land), whether such release actually occurs or arises
before, on or after the Closing Date (the term "release" as used herein means
any spilling, leaking, pumping, pouring, emitting, emptying,

                                       34
<PAGE>
discharging, injecting, escaping, leaching, dumping or disposing into the
ambient environment), including, without limitation, any claim, suit, demand or
action in connection therewith based upon a toxic tort theory (including
damages, costs or expenses for personal injury, medical evaluation or
surveillance or property devaluation) and any claim, demand, action, suit or
proceeding brought or arising under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended ("CERCLA"), or similar state
law; or (iii) the violation by the Corporation or any stockholder, officer,
director, employee or agent of the Corporation prior to the Closing Date of any
law or regulation, whether federal, state or local, governing, relating or
applicable to the environment or the protection thereof; PROVIDED, HOWEVER, that
in each case (i) through (iii) of this Section 12.1(c), the liabilities listed
on Schedule 12.1(c) and the matters described in part 1 of Schedule 6.10 and on
Schedules 6.13(a), 6.13(b), part 1 of 6.13(c), and 6.23, shall be expressly
excluded from the indemnity obligation contained in this Section 12.1(c);
PROVIDED, HOWEVER, that in no event shall any schedules which are
cross-referenced in any such Schedule be excluded from such indemnity
obligations. Purchaser shall not be entitled to assert any claim for
indemnification under this Section 12.1(c) unless and until such time as the
amount of all claims of Purchaser for indemnification hereunder exceeds One
Million Five Hundred Thousand Dollars ($1,500,000) in the aggregate, at which
time any and all claims of Purchaser for indemnification in excess of the One
Million Five Hundred Thousand Dollars ($1,500,000) may be asserted; PROVIDED,
HOWEVER, that the Controlling Shareholders shall not have liability under this
Section 12.1(c) in excess of Two Million Dollars ($2,000,000). The indemnity
obligation contained in this Section 12.1(c) shall relate to claims made within
a period of three (3) years from and after the Closing Date; if prior to the
expiration of such three (3) year period, Purchaser shall have received a
Qualifying Notice (as defined herein) with respect to such claim and provided
notice to the Controlling Shareholders thereof and of Purchaser's intent to seek
indemnification for such claim. A "Qualifying Notice" shall include any of the
following: (i) a notice that the Corporation or its Affiliates, employees or
agents have been designated as a potentially responsible party; (ii) a notice of
violation, notice of deficiency, or formal demand, order or decree from a
governmental agency; (iii) a formal demand or notice of intent to file suit
under any citizen suit provision of any state or federal environmental laws;
(iv) a demand letter or the filing of a lawsuit alleging damages or cleanup
responsibility against the Corporation or its Affiliates, employees or agents;
or (v) a similar written demand or notice alleging liability against the
Corporation, its Affiliates, employees or agents. The Controlling Shareholders'
indemnity obligations for claims made within the three (3) year period following
the Closing Date in accordance with the above-described procedure, shall
continue until the fifth anniversary of the Closing Date; PROVIDED, HOWEVER,
that in the event such claims have not been fully paid or the full amounts have
not become payable or fixed in amounts prior to such date, Purchaser may elect
to have an estimate conducted, in which event the parties shall mutually agree
upon an independent qualified expert to determine the estimated present value of
the claim based on all available information from the parties, from third
parties, from governmental agencies or from any other source such expert deems
appropriate in the circumstances. Such estimate shall be accepted by all parties
as the fixed value of the claim for purposes of this Section 12.1(c), and the
Controlling Shareholders shall pay Purchaser such amount (subject to the Two
Million Dollar ($2,000,000) maximum indemnification liability under this Section
12.1(c) as described above) as if the claim had been due and payable on the
fifth anniversary of the Closing Date. All costs of such estimates

                                       35
<PAGE>
of the expert will be paid by Purchaser.

            (d) The parties hereto agree and acknowledge that the AES
Transaction is an integral part of the transactions contemplated by this
Agreement, and that the Controlling Shareholders will receive substantial
benefit from the AES Transaction. Therefore, the Controlling Shareholders agree
that the indemnification obligations set forth in this Section 12.1 shall
include and encompass the AES Transaction and the representations, warranties,
covenants and other obligations made or undertaken by AES thereunder or pursuant
to the documents delivered thereunder (the "AES Documents"), and that
notwithstanding the terms of the AES Documents, such indemnification obligations
of the Controlling Shareholders shall be in favor of Purchaser. As a result, for
purposes of determining the Controlling Shareholders' indemnification obligation
hereunder, all references in this Section 12.1 to the Corporation shall be
deemed to include AES; any reference to this Agreement shall be deemed to
include the AES Documents; and any reference to Purchaser shall be deemed to
include the Corporation in its capacity as the Purchaser of the AES assets in
the AES Transaction.

            (e) Notwithstanding anything contained in this Section 12.1 to the
contrary, any claim made pursuant to this Section 12.1 shall be reduced by the
amount of any insurance proceeds received by the Corporation with respect to
such claim.

     12.2 ASSUMPTION OF SPECIFIC LIABILITIES. Purchaser agrees to perform all of
the Sellers' contractual obligations related to the Business to the extent, and
only to the extent, such obligations first mature and are required to be
performed by Purchaser after the close of business on the Closing Date.

     12.3 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Each of the
representations and warranties made by the Corporation and the Sellers in this
Agreement or pursuant hereto shall survive for a period of three (3) years
following the Closing Date; PROVIDED, HOWEVER, that the representations and
warranties contained in Sections 6.17, 6.18, and Article 11 shall survive the
Closing Date for the applicable statute of limitation periods. Notwithstanding
any knowledge of facts determined or determinable by any party by investigation,
each party shall have the right to fully rely on the representations,
warranties, covenants and agreements of the other parties contained in this
Agreement or in any other documents or papers delivered in connection herewith.
Each representation, warranty, covenant and agreement of the parties contained
in this Agreement is independent of each other representation, warranty,
covenant and agreement.

     12.4   MATTERS INVOLVING THIRD PARTIES.

               (a) If any third party shall notify Purchaser or any of the
Sellers with respect to any matter (a "Third Party Claim") which may give rise
to a claim for indemnification against the other party under this Article 12,
then the party receiving such Third Party Claim shall promptly notify the other
party in writing; PROVIDED, HOWEVER, that no delay on the part of the notifying
party in notifying the other party shall relieve such party from any obligation
hereunder unless (and then solely to the extent) the indemnifying party is
thereby prejudiced.

                                       36
<PAGE>
               (b) The indemnifying party will have the right to defend the
notifying party against Third Party Claim with counsel of its choice reasonably
satisfactory to the other party, so long as the indemnifying party notifies the
notifying party in writing within thirty (30) days after the making of a Third
Party Claim. The notifying party may retain separate co-counsel at its sole cost
and expense and participate in the defense of the Third Party Claim. Neither
party will consent to the entry of any judgment or enter into any settlement
which does 22not include as an unconditional term thereof the giving to the
notifying party by the third party of a release of all liability in respect of
such Third Party Claim or which seeks an injunction, specific performance or a
declaration of rights or other equitable relief that, in the good faith judgment
of notifying party, will likely have a material adverse effect on the notifying
party's operations without the prior written consent of the notifying party
which shall not be withheld unreasonably.
