         earnings (or losses) on deferred compensation payment obligations based

Item 3.  Incorporation of Documents by Reference
         ---------------------------------------

         The following documents previously filed by OHM Corporation (the
"Registrant" or the "Company") with the Securities and Exchange Commission (the
"Commission") are incorporated herein by reference: the Company's Annual Report
on Form 10-K for the fiscal year ended December 31, 1995 (File No. 1-09654);
Quarterly Reports on Form 10-Q for the quarters ended March 31, 1996, June 30,
1996 and September 30, 1996 (File No. 1-09654); and the description of Common
Stock, par value $.10 per share ("Common Stock") contained in the Registration
Statement on Form 8-A filed on August 4, 1987 (File No. 1-09654).

         All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, prior to the
filing of a post-effective amendment which indicates that all securities offered
have been sold or which deregisters all securities then remaining unsold, shall
be deemed to be incorporated herein by reference and to be part hereof from the
date of filing of such documents.

Item 4.   Description of Securities
          -------------------------

         Under the OHM Corporation Retirement and Incentive Compensation Plan
(the "Plan"), the Company will provide eligible employees the opportunity to
defer a specified percentage of their cash compensation. The obligations of the
Company under the Plan (the "Deferred Compensation Obligations") will be
unsecured general obligations of the Company to pay the deferred compensation in
the future in accordance with the terms of the Plan, and will rank pari passu
with other unsecured and unsubordinated indebtedness of the Company from time to
time outstanding.

         The amount of compensation to be deferred by each participating
employee will be determined in accordance with the Plan based on elections by
the employee. Each Deferred Compensation Obligation will be payable in
accordance with the terms of the Plan. Under the Plan, participants may elect to
invest deferred compensation in a "Retirement Deferral Account" or an "OHM
Common Stock Deferral Account." The Retirement Deferral Account will be credited
with compensation that the participant elects to defer, Company matching
contributions and interest. The "OHM Common Stock Deferral Account" will be
credited with Company matching contributions and with compensation that the
participant elects to defer in a manner such that the amount deferred will be
treated as if such amount had been used to purchase shares of the Registrant's
Common Stock. This is, however, only an bookkeeping entry and not an actual
purchase of the Registrant's Common Stock. For purposes of this Registration
Statement, these investments are referred to as Units. The value of the Units
will fluctuate based on changes in the value of OHM Corporation Common Stock. To
the extent that dividends are paid on OHM Corporation Common Stock, a like
amount will be added to the participant's account and, reinvested in Units. This
right to accrue earnings (or losses) based on fluctuations in the value of OHM
Corporation Common Stock is being registered on this Registration Statement on
Form S-8.

         An employee participant's right or the right of any other person to the
Deferred Compensation Obligations cannot be alienated, commuted, anticipated or
assigned. The Deferred Compensation Obligations are not subject to the debts,
contracts, liabilities, engagements or torts of any person entitled to receive
benefits under the Plan.

         The Board of Directors of the Company may amend, suspend or terminate
the Plan at any time. However, no Plan amendment, suspension or termination may
adversely effect amounts deferred by the participant to the Plan (other than
employer matching contributions and the rate or calculation of interest).

Item 5.   Interests of Named Experts and Counsel
          --------------------------------------

         The Opinion of Counsel as to the legality of the securities being
issued (constituting Exhibit 5) has been rendered by counsel who is a full-time
employee of the Registrant.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

         Article V of the Registrant's Regulations provides that the Registrant
shall indemnify its directors, officers and employees, and may indemnify its
agents, to the fullest extent permitted by law under prescribed conditions and
subject to various qualifications. Article V of the Regulations is set forth in
Section (a) under the caption "Indemnification of Directors and Officers" in the
Registration Statement on Form S-8 (File No. 33-55371) that was filed with the
Commission on September 2, 1994.

         Reference is made to Section 1701.13(E) of the Ohio Revised Code
relating to indemnification of directors, officers, employees and agents of an
Ohio corporation.

         The Registrant has entered into amended and restated indemnification
agreements with its directors and officers that indemnify them against many of
the types of claims that may be made against them. A Form of Amended and
Restated Indemnification Agreement was filed as Exhibit 10.9 to the Registrant's
Form 10-K for the year ended December 31, 1995.

         ------------

         (a)      The undersigned Registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales
                           are being made, a post-effective amendment to this
                           Registration Statement:

                           (i)      To include any prospectus required by 
                                    Section 10(a)(3) of the Securities Act;

                           (ii)     To reflect in the prospectus any facts or
                                    events arising after the effective date of
                                    the Registration Statement (or the most
                                    recent post-effective amendment thereof)
                                    which, individually or in the aggregate,
                                    represent a fundamental change in the
                                    information set forth in the Registration
                                    Statement. Notwithstanding the foregoing,
                                    any increase or decrease in volume of
                                    securities offered (if the total dollar
                                    value of securities offered would not exceed
                                    that which was registered) and any deviation

                                    maximum offering range may be reflected in
                                    the form of prospectus filed with the

                                    424(b) if, in the aggregate, the changes in
                                    volume and price represent no more than a
                                    20% change in the maximum aggregate offering
                                    price set forth in the "Calculation of
                                    Registration Fee" table in the effective
                                    Registration Statement;

                           (iii)    To include any material information with
                                    respect to the plan of distribution not
                                    previously disclosed in the Registration
                                    Statement or any material change to such
                                    information in the Registration Statement;

                  PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the Registration Statement is on Form S-3 or Form
                  S-8, and the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed by the Registrant pursuant to Section
                  13 or Section 15(d) of the Exchange Act that are incorporated
                  by reference in the Registration Statement.

                  (2)      That, for the purpose of determining any liability
                           under the Securities Act, each such post-effective
                           amendment shall be deemed to be a new Registration
                           Statement relating to the securities offered therein,
                           and the offering of such securities at that time
                           shall be deemed to be the initial bona fide offering
                           thereof.

                  (3)      To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered which remain unsold at the termination of
                           the offering.

         (b)      The undersigned Registrant hereby undertakes that, for
                  purposes of determining any liability under the Securities
                  Act, each filing of the Registrant's annual report pursuant to
                  Section 13(a) or Section 15(d) of the Exchange Act (and, where
                  applicable, each filing of an employee benefit plan's annual
                  report pursuant to Section 15(d) of the Exchange Act) that is
                  incorporated by reference in the Registration Statement shall
                  be deemed to be a new Registration Statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be in the initial
                  bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the
                  Securities Act may be permitted to directors, officers and
                  controlling persons of the Registrant pursuant to the
                  foregoing provisions, or otherwise, the Registrant has been
                  advised that in the opinion of the Commission such
                  indemnification is against public policy as expressed in the
                  Act and is, therefore, unenforceable. In the event that a
                  claim for indemnification against such liabilities (other than
                  the payment by the Registrant of expenses incurred or paid by
                  a director, officer or controlling person of the Registrant in
                  the successful defense of any action, suit or proceeding) is
                  asserted by such director, officer or controlling person in
                  connection with the securities being registered, the
                  Registrant will, unless in the opinion of its counsel the
                  matter has been settled by controlling precedent, submit to a
                  court of appropriate jurisdiction the question of whether such
                  indemnification by it is against public policy as expressed in
                  the Act and will be governed by the final adjudication of such
                  issue.
