          5. Agreements of the Company and the Guarantors. As of the date
             -----------------------------------------------
hereof, each of the Company and the Guarantors (other than the EFM Subsidiaries)
and, as of the consummation of the EFM Acquisition, each of the EFM
Subsidiaries, hereby agrees with the Initial Purchasers as follows:

          (a) To advise the Initial Purchasers promptly and, if requested by the
Initial Purchasers, confirm such advice in writing, (i) to the extent the
Company is aware, of the issuance by any state securities commission of any stop
order suspending the qualification or exemption from qualification of any Series
A Notes for offering or sale in any jurisdiction designated by the Initial
Purchasers pursuant to Section 5(e) hereof, or the initiation of any proceeding
by any state securities commission or any other federal or state regulatory
authority for such purpose and (ii) of the happening of any event during the
period referred to in Section 5(c) below that makes any statement of a material
fact made in the Preliminary Offering Memorandum or the Offering Memorandum
untrue or that requires any additions to or changes in the Preliminary Offering
Memorandum or the Offering Memorandum in order to make the statements therein
not misleading.  The Company and the Guarantors shall use all commercially
reasonable efforts to prevent the issuance of any stop order or order suspending
the qualification or exemption of any Series A Notes under any state securities
or Blue Sky laws and, if at any time any state securities commission or other
federal or state regulatory authority shall issue an order suspending the
qualification or exemption of any Series A Notes under any state securities or
Blue Sky laws, the Company and the Guarantors shall use all commercially
reasonable efforts to obtain the withdrawal or lifting of such order at the
earliest possible time.

          (b) To furnish the Initial Purchasers and those persons identified by
the Initial Purchasers to the Company as many copies of the Preliminary Offering
Memorandum and the Offering Memorandum, and any amendments or supplements
thereto, as the Initial Purchasers may reasonably request for the time period
specified in Section 5(c).  Subject to the Initial Purchasers' compliance with
their respective representations and warranties and agreements set forth in
Section 7 hereof, the Company consents to the use of the Preliminary Offering
Memorandum and the Offering Memorandum, and any amendments and supplements
thereto required pursuant hereto, by the Initial Purchasers in connection with
Exempt Resales.

          (c) During such period as in the opinion of counsel for the Initial
Purchasers an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchasers and in connection with
market-making activities of the Initial Purchasers for so long as any Series A
Notes are outstanding, (i) not to make any amendment or supplement to the
Offering Memorandum of which the Initial Purchasers shall not previously have
been advised or to which the Initial Purchasers shall reasonably object after
being so advised and (ii) to prepare promptly upon the Initial Purchasers'
reasonable request, any amendment or supplement to the Offering Memorandum which
may be necessary or advisable in connection with such Exempt Resales or such
market-making activities.

          (d) If, during the period referred to in Section 5(c) above, any event
shall occur or condition shall exist as a result of which, in the opinion of
counsel to the Initial Purchasers, it becomes necessary to amend or supplement
the Offering Memorandum in order to make the statements therein, in the light of
the circumstances when such Offering Memorandum is delivered to an Eligible
Purchaser, not misleading, or if, in the opinion of counsel to the Initial
Purchasers, it is necessary to amend or supplement the Offering Memorandum to
comply with any applicable law, and to prepare an appropriate amendment or
supplement to such Offering Memorandum so that the statements therein, as so
amended or supplemented, will not, in the light of the circumstances when it is
so delivered, be 

                                       4

 
misleading, or so that such Offering Memorandum will comply with applicable law,
and to furnish to the Initial Purchasers and such other persons as the Initial
Purchasers may designate such number of copies thereof as the Initial Purchasers
may reasonably request.

          (e) Prior to the sale of all Series A Notes pursuant to Exempt Resales
as contemplated hereby, to cooperate with the Initial Purchasers and counsel to
the Initial Purchasers in connection with the registration or qualification of
the Series A Notes for offer and sale to the Initial Purchasers and pursuant to
Exempt Resales under the securities or Blue Sky laws of such jurisdictions as
the Initial Purchasers may request and to continue such registration or
qualification in effect so long as required for Exempt Resales and to file such
consents to service of process or other documents as may be necessary in order
to effect such registration or qualification; provided, however, that neither
the Company nor any Guarantor shall be required in connection therewith to
qualify as a foreign corporation in any jurisdiction in which it is not now so
qualified or to take any action that would subject it to general consent to
service of process or taxation other than as to matters and transactions
directly relating to the Preliminary Offering Memorandum, the Offering
Memorandum or Exempt Resales, in any jurisdiction in which it is not now so
subject.

          (f) For five years from the date hereof, to furnish to the Initial
Purchasers as soon as available copies of all reports or other communications
furnished by the Company or any of the Guarantors to its security holders or
furnished to or filed with the Commission or any national securities exchange on
which any class of securities of the Company or any of the Guarantors is listed
and such other publicly available information concerning the Company and/or its
subsidiaries, including without limitation, press releases, as the Initial
Purchasers may reasonably request.

          (g) So long as any of the Series A Notes remain outstanding and during
any period in which the Company and the Guarantors are not subject to Section 13
or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
                                                                  --------
Act"), to make available to any holder of Series A Notes in connection with any
- ---
sale thereof and any prospective purchaser of such Series A Notes from such
holder, the information ("Rule 144A Information") required by Rule 144A(d)(4)
                          ---------------------                              
under the Act.

          (h) Whether or not the transactions contemplated in this Agreement are
consummated or this Agreement is terminated, to pay or cause to be paid all
expenses incident to the performance of the obligations of the Company and the
Guarantors under this Agreement, including:  (i) the fees, disbursements and
expenses of counsel to the Company and the Guarantors and accountants of the
Company and the Guarantors in connection with the sale and delivery of the
Series A Notes to the Initial Purchasers and pursuant to Exempt Resales, and all
other fees and expenses in connection with the preparation, printing, filing and
distribution of the Preliminary Offering Memorandum, the Offering Memorandum and

          7. Initial Purchasers' Representations and Warranties. Each of the
             --------------------------------------------------
Initial Purchasers, severally and not jointly, represents and warrants to the
Company and the Guarantors, and agrees that:

          (a) Such Initial Purchaser is either a QIB or an Accredited
Institution, in either case, with such knowledge and experience in financial and
business matters as is necessary in order to evaluate the merits and risks of an
investment in the Series A Notes.

          (b) Such Initial Purchaser (A) is not acquiring the Series A Notes

other applicable jurisdiction and (B) will be reoffering and reselling the
Series A Notes only to (x) QIBs in reliance on the exemption from the
registration requirements of the Act provided by Rule 144A or (y) in offshore

          (c) Such Initial Purchaser agrees that no form of general solicitation

are QIBs, and (B) Regulation S Purchasers, in each case, that agree that (x) the
Series A Notes purchased by them may be resold, pledged or otherwise transferred
within the time period referred to under Rule 144(k) (taking into account the
provisions of Rule 144(d) under the Act, if applicable) under the Act, as in
effect on the date of the transfer of such Series A Notes, only (I) to the
Company or any of its subsidiaries, (II) to a person whom the seller 

                                       14

of counsel acceptable to the Company that such transfer is in compliance with
the Act, (VI) in accordance with another exemption from the registration
requirements of the Act (and based upon an opinion of counsel acceptable to the
Company) or (VII) pursuant to an effective registration statement and, in each
case, in accordance with the applicable securities laws of any state of the
United States or any other applicable jurisdiction and (y) they will deliver to
each person to whom such Series A Notes or an interest therein is transferred a
notice substantially to the effect of the foregoing.

          (e) Such Initial Purchaser and its affiliates or any person acting on
its or their behalf have not engaged or will not engage in any directed selling
efforts within the meaning of Regulation S with respect to the Series A Notes or
the Subsidiary Guarantees.

          (f) The Series A Notes offered and sold by such Initial Purchaser
pursuant hereto in reliance on Regulation S have been and will be offered and
sold only in offshore transactions.

          (g) The sale of the Series A Notes offered and sold by such Initial
Purchaser pursuant hereto in reliance on Regulation S is not part of a plan or
scheme to evade the registration provisions of the Act.

          (h) Such Initial Purchaser agrees that it has not offered or sold and
will not offer or sell the Series A Notes in the United States or to, or for the
benefit or account of, a U.S. Person (other than a distributor), in each case,
as defined in Rule 902 under the Act (i) as part of its distribution at any time
and (ii) otherwise until 40 days after the later of the commencement of the
offering of the Series A Notes pursuant hereto and the Closing Date, other than
in accordance with Regulation S of the Act or another exemption from the
registration requirements of the Act.  Such Initial Purchaser agrees that,
during such 40-day distribution compliance period, it will not cause any
advertisement with respect to the Series A Notes (including any "tombstone"
advertisement) to be published in any newspaper or periodical or posted in any
public place and will not issue any circular relating to the Series A Notes,
except such advertisements as are permitted by and include the statements
required by Regulation S.

          (i) Such Initial Purchaser agrees that, at or prior to confirmation of
a sale of Series A Notes by it to any distributor, dealer or person receiving a
selling concession, fee or other remuneration during the 40-day distribution
compliance period referred to in Rule 903(c)(2) under the Act, it will send to
such distributor, dealer or person receiving a selling concession, fee or other
remuneration a confirmation or notice to substantially the following effect:

     "The Series A Notes covered hereby have not been registered under the U.S.
     Securities Act of 1933, as amended (the "Securities Act"), and may not be
     offered and sold within the United States or to, or for the account or
     benefit of, U.S. persons (i) as part of your distribution at any time or
     (ii) otherwise until 40 days after the later of the commencement of the
     Offering and the Closing Date, except in either case in accordance with
     Regulation S under the Securities Act (or Rule 144A or to Accredited
     Institutions in transactions that are exempt from the registration
     requirements of the Securities Act), and in connection with any subsequent
     sale by you of the Series A Notes covered hereby in reliance on Regulation
     S during the period referred to above to any distributor, dealer or person
     receiving a selling concession, fee or other remuneration, you 

                                       15

 
     must deliver a notice to substantially the foregoing effect. Terms used
     above have the meanings assigned to them in Regulation S."

          Such Initial Purchaser acknowledges that the Company and the
Guarantors and, for purposes of the opinions to be delivered to each Initial
Purchaser pursuant to Section 9 hereof, counsel to the Company and the
Guarantors and counsel to the Initial Purchaser will rely upon the accuracy and
truth of the foregoing representations and Such Initial Purchaser hereby
consents to such reliance.

          8.  Indemnification.
              ----------------

          (a) The Company and each Guarantor agree, jointly and severally, to
indemnify and hold harmless the Initial Purchasers, their directors, their
officers and each person, if any, who controls such Initial Purchaser within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
against any and all losses, claims, damages, liabilities and judgments
(including, without limitation, any reasonable legal or other expenses incurred
in connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Offering Memorandum (or any amendment or
supplement thereto), the Preliminary Offering Memorandum or any Rule 144A
Information provided by the Company or any Guarantor to any holder or
prospective purchaser of Series A Notes pursuant to Section 5(h) or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or judgments are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to an Initial Purchaser furnished in
writing to the Company by such Initial Purchaser; provided, however, that the
foregoing indemnity agreement with respect to any Preliminary Offering
Memorandum shall not inure to the benefit of any Initial Purchaser who failed to
deliver a Final Offering Memorandum, as then amended or supplemented, (so long
as the Offering Memorandum and any amendment or supplement thereto was provided
by the Company to the several Initial Purchasers in the requisite quantity and
on a timely basis to permit proper delivery on or prior to the Closing Date) to
the person asserting any losses, claims, damages, liabilities or judgments
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Offering Memorandum, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, if such material
misstatement or omission or alleged material misstatement or omission was cured
in the Offering Memorandum, as so amended or supplemented.

          (b) Each of the Initial Purchasers, severally and not jointly, agrees
to indemnify and hold harmless the Company and the Guarantors, and their
respective directors and officers and each person, if any, who controls (within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the
Company or the Guarantors, to the same extent as the foregoing indemnity from
the Company and the Guarantors to the Initial Purchaser but only with reference
to information relating to such Initial Purchaser furnished in writing to the
Company by such Initial Purchaser expressly for use in the Preliminary Offering
Memorandum or the Offering Memorandum, and not with respect to the information
provided by any other Initial Purchaser.

          (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
                                                                              
"indemnified party"), the indemnified party shall promptly notify the person
- ------------ -----                                                          
against whom such indemnity may be sought (the "indemnifying party") in writing
                                                ------------------             
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of 

                                       16

 
which indemnity may be sought pursuant to both Sections 8(a) and 8(b), the
Initial Purchasers shall not be required to assume the defense of such action
pursuant to this Section 8(c), but may employ separate counsel and participate
in the defense thereof, but the reasonable fees and expenses of such counsel,
except as provided below, shall be at the expense of the Initial Purchasers).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such reasonable fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing by
Donaldson, Lufkin & Jenrette Securities Corporation, in the case of the parties
indemnified pursuant to Section 8(a), and by the Company, in the case of parties
indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and
hold harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty business days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of the indemnifying party) and, prior to the
date of such settlement, the indemnifying party shall have failed to comply with
such reimbursement request. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

          (d) To the extent the indemnification provided for in this Section 8
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Guarantors, on the one hand, and the Initial Purchasers on the
other hand from the offering of the Series A Notes or (ii) if the allocation
provided by clause 8(d)(i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause 8(d)(i) above but also the relative fault of the Company and the
Guarantors, on the one hand, and the Initial Purchasers on the other hand, in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations.  The relative benefits received by the Company and the
Guarantors, on the one hand and the Initial Purchasers, on the other hand, shall
be deemed to be in the same proportion as the total net proceeds from the
offering of the Series A Notes (after underwriting discounts and commissions,
but before deducting expenses) received by the Company, and the total discounts
and commissions received by the Initial Purchasers bear to the total price to
investors of the 

                                       17

 
Series A Notes, in each case as set forth in the table on the cover page of the
Offering Memorandum. The relative fault of the Company and the Guarantors, on
the one hand, and the Initial Purchasers, on the other hand, shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Guarantors,
on the one hand, or the Initial Purchasers, on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

          The Company and the Guarantors, and the Initial Purchasers agree that
it would not be just and equitable if contribution pursuant to this Section 8(d)
were determined by pro rata allocation (even if the Initial Purchasers were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph.  The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities or judgments
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such indemnified party in connection with investigating or defending any
matter, including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 8, the Initial Purchasers shall not be required to contribute any amount
in excess of the amount by which the total discounts and commissions received by
such Initial Purchasers exceeds the amount of any damages which the Initial
Purchasers have otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.   No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Initial Purchasers' obligations to contribute
pursuant to this Section 8(d) are several in proportion to the respective
principal amount of Series A Notes purchased by each of the Initial Purchasers
hereunder and not joint.

          (e) The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

          9. Conditions of Initial Purchaser's Obligations. The obligations of
             ---------------------------------------------
the Initial Purchasers to purchase the Series A Notes under this Agreement are
subject to the satisfaction of each of the following conditions:

          (a) All the representations and warranties of the Company and the
Guarantors contained in this Agreement shall be true and correct on the Closing
Date with the same force and effect as if made on and as of the Closing Date.

          (b) Subsequent to the execution and delivery of this Agreement and
prior to the Closing Date, (i) there shall not have occurred any downgrading,
suspension or withdrawal of, nor shall any notice have been given of any
potential or intended downgrading, suspension or withdrawal of, or of any review
(or of any potential or intended review) for a possible change that does not
indicate the direction of the possible change in, any rating accorded any
securities of the Company or any Guarantor (including, without limitation, the
placing of any of the foregoing ratings on credit watch with negative or
developing implications or under review with an uncertain direction) by any
"nationally recognized statistical rating organization" as such term is defined
for purposes of Rule 436(g)(2) under the Act, (ii) there shall not have occurred
any change, nor shall any notice have been given of any potential or intended
change, in the outlook for any rating of the Company or any Guarantor or any
securities of the Company or any Guarantor by any such rating organization and
(iii) no such rating organization shall 

                                       18

 
have given notice that it has assigned (or is considering assigning) a lower
rating to the Notes than that on which the Notes were marketed.

          (c) Since the respective dates as of which information is given in the
Offering Memorandum, other than as set forth in the Offering Memorandum
(exclusive of any amendments or supplements thereto subsequent to the date of
this Agreement), (i) there shall not have occurred any change or any development
that, singly or in the aggregate, is reasonably likely to have a material
adverse effect on the condition, financial or otherwise, or the earnings,
business, management or operations of the Company and its subsidiaries, taken as
a whole, (ii) there shall not have been any change or any development that,
singly or in the aggregate, is reasonably likely to have a material adverse
effect on the capital stock or in the long term debt of the Company or any of
its subsidiaries and (iii) neither the Company nor any of its subsidiaries shall
have incurred any liability or obligation, direct or contingent, the effect of
which, in any such case described in clause 9(c)(i), 9(c)(ii) or 9(c)(iii), in
your judgment, is material and adverse and, in your judgment, makes it
impracticable to market the Series A Notes on the terms and in the manner
contemplated in the Offering Memorandum.

          (d) You shall have received on the Closing Date (a) a certificate
dated the Closing Date, signed by the Vice President and Treasurer of the
Company and (b) certificates dated the Closing Date, signed by the Vice
President and Treasurer of each of the Guarantors, which certificates shall
confirm the matters set forth in Sections 6(q), 6(aa), 9(a) and 9(b) and state
that each of the Company and the Guarantors has complied with all the agreements
and satisfied all of the conditions herein contained and required to be complied
with or satisfied on or prior to the Closing Date.

          (e) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Initial Purchasers), dated the Closing
Date, of Gibson, Dunn & Crutcher LLP, counsel for the Company and the
Guarantors, to the effect that:

               "Covered Guarantors") have been duly incorporated, are validly
               -------------------                                           
               existing as corporations in good standing under the laws of their
               respective jurisdictions of incorporation and have the corporate
               power and authority to carry on their respective businesses as
               described in the Offering Memorandum and to own, lease and
               operate their respective properties;

                    (ii) the Company is duly qualified and in good standing as a
               foreign corporation authorized to do business in the
               jurisdictions listed under its name on Schedule D attached

                    (iii)  the Series A Notes have been duly authorized and,
               when executed and authenticated in accordance with the provisions
               of the Indenture and delivered to and paid for by the Initial
               Purchasers in accordance with the terms of this Agreement, will
               be entitled to the benefits of the Indenture and will be valid
               and binding obligations of the Company, enforceable in accordance
               with their terms except as the enforceability thereof may be
               limited by (x) bankruptcy, insolvency or similar laws affecting
               creditors' rights generally (including, without limitation, the
               effect of statutory or other laws regarding fraudulent transfers
               or preferential transfers) and (y) equitable principles of
               general applicability;

               suspension or revocation of any Authorization (as defined below)
               of the Company or any of its subsidiaries.

                    (x) the Company is not and, after giving effect to the
               offering and sale of the Series A Notes and the application of
               the net proceeds thereof as described in the Offering Memorandum,
               will not be, an "investment company" as such term is defined in
               the Investment Company Act of 1940, as amended;

                    (xi) the Indenture complies as to form in all material
               respects with the requirements of the TIA, and the rules and
               regulations of the Commission applicable to an indenture which is
               qualified thereunder.  It is not necessary in connection with the
               offer, sale and delivery of the Series A Notes to the Initial
               Purchasers in the manner contemplated by this Agreement or in
               connection with the Exempt Resales to qualify the Indenture under

               set forth in Sections 6(dd), (ee) and (ff) of this Agreement.

          In addition, Gibson, Dunn & Crutcher LLP shall state that, in the
course of the preparation by the Company of the Offering Memorandum, such
counsel has participated in conferences and discussions with officers and other
representatives of the Company and others at which the contents of the Offering
Memorandum were discussed.  Although such counsel has not independently
verified, is not passing upon and does not assume responsibility for the
accuracy, completeness or fairness of the statements and information included in
the Offering Memorandum, no facts have come to such counsel's attention which
cause such counsel to believe that the Offering Memorandum (except for any
financial statements and notes and schedules thereto, pro form financial
information or other financial or accounting data contained or incorporated by
reference therein, as to all of which such counsel makes no comment), as of the
date thereof and as of the Closing Date, contained any untrue statement of a
material fact or omitted to state any material fact necessary to make the
statements made therein, in light of the circumstances under which they are
made, not misleading.

          The opinion of  Gibson, Dunn & Crutcher LLP described in Section 9(e)
above shall be rendered to you at the request of the Company and the Guarantors
and shall so state therein.

               set forth in Article 11 therein) has been duly authorized,
               executed and delivered by the Foreign Guarantors, other than the

               Report on Form 10-K for the year ended December 25, 1998, which
               default, individually or in the aggregate, would be reasonably
               likely to have a Material Adverse Effect;

                    (viii)  the execution, delivery and performance of this
               Agreement and the other Operative Documents by the Guarantors,
               other than the Covered Guarantors, the compliance by each of the

               loan agreement, mortgage, lease or other agreement or instrument
               that is material to the Company and its subsidiaries, taken as a
               whole, to which the Company or any of its subsidiaries is a party
               or by which the Company or any of its subsidiaries or their
               respective property is bound, (iii) violate or conflict with any
               applicable law or any rule, regulation, judgment, order or decree

               respective property, (iv) result in the imposition or creation of
               (or the obligation to create or impose) a Lien under any

               subsidiaries is a party or by which the Company or any of its
               subsidiaries or their respective property is bound, or (v) result
               in the termination, suspension or revocation of any Authorization
               (as defined below) of the Company or any of its subsidiaries or
               result in any other impairment of the rights of the holder of any
               such Authorization.

                    (ix) except as disclosed in the Offering Memorandum, after
               due inquiry, such counsel does not know of any legal or
               governmental proceedings pending or threatened to which the
               Company  or any of its subsidiaries is or could be a party or to
               which any of their respective property is or could be subject,
               which might result, singly or in the aggregate, in a Material
               Adverse Effect.

                    (x) to the knowledge of such counsel, neither the Company
               nor any of its subsidiaries has violated any Environmental Law or
               any provisions of ERISA, any provisions of the Foreign Corrupt
               Practices Act or the rules and regulations promulgated
               thereunder, except for such violations which, singly or in the
               aggregate, would not have a Material Adverse Effect;

                    (xi) each of the Company and its subsidiaries has such
               Authorizations of, and has made all filings with and notices to,
               all governmental or regulatory authorities and self-regulatory
               organizations and all courts and other tribunals, including
               without limitation, under any applicable Environmental Laws, as
               are necessary to own, lease, license and operate its respective
               properties and to conduct its business, except where the failure
               to have any such Authorization or to make any such filing or
               notice would not, singly or in the aggregate, have a Material
               Adverse Effect.  To the best of such counsel's knowledge, (a)
               each such Authorization is valid and in full force and effect and
               each of the Company and its subsidiaries is in compliance with
               all the terms and conditions thereof and with the rules and
               regulations of the authorities and governing bodies having
               jurisdiction with respect thereto; (b) no event has occurred
               (including the receipt of any notice from any authority or
               governing body) which allows or, after notice or lapse of time or
               both, would allow, revocation, suspension or termination of any
               such Authorization or results or, after notice or lapse of time
               or both, would result in any other impairment of the rights of
               the holder of any such Authorization; (c) and such Authorizations
               contain no restrictions that are burdensome to the Company or any
               of its subsidiaries; except where such failure to comply with
               clauses (a), (b) or (c) would not, singly or in the aggregate, be
               reasonably expected to have a Material Adverse Effect;

                                       23

 
                    (xii)  to the best of such counsel's knowledge after due
               inquiry, and except as disclosed in the Offering Memorandum there
               are no contracts, agreements or understandings between the
               Company or any Guarantor and any person granting such person the
               right to require the Company or such Guarantor to include such
               securities with the Notes and Subsidiary Guarantees registered
               pursuant to any Registration Statement;

          In addition, such counsel shall state that, in the course of the
preparation by the Company and the Guarantors of the Offering Memorandum, such
counsel has participated in conferences and discussions with officers and other
representatives of the Company and others at which the contents of the Offering
Memorandum were discussed.  Although such counsel has not independently
verified, is not passing upon and does not assume responsibility for the
accuracy, completeness or fairness of the statements and information included in
the Offering Memorandum, no facts have come to such counsel's attention which
cause such counsel to believe that the Offering Memorandum (except for any
financial statements and notes and schedules thereto, pro form financial
information or other financial or accounting data contained or incorporated by
reference therein, as to all of which such counsel make no comment), as of the
date thereof and as of the Closing Date, contained any untrue statement of a
material fact or omitted to state any material fact necessary to make the
statements made therein, in light of the circumstances under which they are
made, not misleading.

               default under, the charter or by-laws of Beneco and OHM
               Remediation (as applicable), and

               (q) Each condition to the closing of the Acquisitions shall have
been satisfied or waived. There shall exist at and as of the Closing Date no
conditions that would constitute a default under the Acquisition Agreements. On
the Closing Date, the Acquisitions shall have been consummated on terms that
conform in all material respects to the description thereof in the Offering
Memorandum and the Initial Purchasers shall have received evidence satisfactory
to the Initial Purchasers of the consummation thereof.

          10. Effectiveness of Agreement and Termination. This Agreement shall
              ------------------------------------------
become effective upon the execution and delivery of this Agreement by the
parties hereto.

          This Agreement may be terminated at any time on or prior to the
Closing Date by the Initial Purchasers by written notice to the Company if any
of the following has occurred:  (i) any 

                                       25

 
outbreak or escalation of hostilities or other national or international
calamity or crisis or change in economic conditions or in the financial markets
of the United States or elsewhere that, in the Initial Purchasers' judgment, is
material and adverse and, in the Initial Purchasers' judgment, makes it
impracticable to market the Series A Notes on the terms and in the manner
contemplated in the Offering Memorandum, (ii) the suspension or material
limitation of trading in securities or other instruments on the New York Stock
Exchange, the American Stock Exchange, the Chicago Board of Options Exchange,
the Chicago Mercantile Exchange, the Chicago Board of Trade or the Nasdaq
National Market or limitation on prices for securities or other instruments on
any such exchange or the Nasdaq National Market, (iii) the suspension of trading
of any securities of the Company or any Guarantor on any exchange or in the 
over-the-counter market, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority that in the opinion of the Initial
Purchasers materially and adversely affects, or will materially and adversely
affect, the business, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole, (v) the declaration of a banking
moratorium by either federal or New York State authorities or (vi) the taking of
any action by any federal, state or local government or agency in respect of its
monetary or fiscal affairs that in the opinion of the Initial Purchasers has a
material adverse effect on the financial markets in the United States.

          If on the Closing Date any one or more of the Initial Purchasers shall
fail or refuse to purchase the Series A Notes which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of the Series
A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the
case may be, agreed but failed or refused to purchase is not more than one-tenth
of the aggregate principal amount of the Series A Notes to be purchased on such
date by all Initial Purchasers, each non-defaulting Initial Purchaser shall be
obligated severally, in the proportion which the principal amount of the Series
A Notes set forth opposite its name in Schedule B bears to the aggregate
principal amount of the Series A Notes which all the non-defaulting Initial
Purchasers, as the case may be, have agreed to purchase, or in such other
proportion as you may specify, to purchase the Series A Notes which such
defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed
but failed or refused to purchase on such date; provided that in no event shall
the aggregate principal amount of the Series A Notes which any Initial Purchaser
has agreed to purchase pursuant to Section 2 hereof be increased pursuant to
this Section 10 by an amount in excess of one-ninth of such principal amount of
the Series A Notes without the written consent of such Initial Purchaser.  If on
the Closing Date any Initial Purchaser or Initial Purchasers shall fail or
refuse to purchase the Series A Notes and the aggregate principal amount of the
Series A Notes with respect to which such default occurs is more than one-tenth
of the aggregate principal amount of the Series A Notes to be purchased by all
Initial Purchasers and arrangements satisfactory to the Initial Purchasers and
the Company for purchase of such the Series A Notes are not made within 48 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Initial Purchaser and the Company.   In any such case
which does not result in termination of this Agreement, either you or the
Company shall have the right to postpone the Closing Date, but in no event for
longer than seven days, in order that the required changes, if any, in the
Offering Memorandum or any other documents or arrangements may be effected.  Any
action taken under this paragraph shall not relieve any defaulting Initial
Purchaser from liability in respect of any default of any such Initial Purchaser
under this Agreement.

          11.  Dissolution of Certain Subsidiaries. The Company shall use all
               -----------------------------------
commercially reasonable efforts to dissolve the subsidiaries listed on Schedule
E attached hereto as soon as practicable after the date hereof.

          12. Miscellaneous. Notices given pursuant to any provision of this
              -------------
Agreement shall be addressed as follows: (i) if to the Company or any Guarantor,
to The IT Group, Inc., 2790 Mosside Boulevard, Monroeville, Pennsylvania 15146-
2792, Attention: General Counsel and (ii) if to the Initial 

                                       26

 
Purchasers, Donaldson, Lufkin & Jenrette Securities Corporation, 277 Park
Avenue, New York, New York 10172, Attention: Syndicate Department, or in any
case to such other address as the person to be notified may have requested in
writing.

          The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company, the Guarantors and the Initial
Purchases set forth in or made pursuant to this Agreement shall remain operative
and in full force and effect, and will survive delivery of and payment for the
Series A Notes, regardless of (i) any investigation, or statement as to the
results thereof, made by or on behalf of the Initial Purchasers, the officers or
directors of the Initial Purchasers, any person controlling the Initial
Purchasers, the Company, any Guarantor, the officers or directors of the Company
or any Guarantor, or any person controlling the Company or any Guarantor, (ii)
acceptance of the Series A Notes and payment for them hereunder and (iii)
termination of this Agreement.

          If for any reason the Series A Notes are not delivered by or on behalf
of the Company as provided herein (other than as a result of any termination of
this Agreement pursuant to Section 10), the Company and each Guarantor, jointly
and severally, agree to reimburse the Initial Purchasers for all reasonable out-
of-pocket expenses (including the reasonable fees and disbursements of counsel)
incurred by them.  Notwithstanding any termination of this Agreement, the
Company shall be liable for all expenses which it has agreed to pay pursuant to
Section 5(i) hereof.  The Company and each Guarantor also agree, jointly and
severally, to reimburse the Initial Purchasers and their respective officers,
directors and each person, if any, who controls such Initial Purchasers within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act for any
and all reasonable fees and expenses (including without limitation the
reasonable fees and expenses of counsel) incurred by them in connection with
enforcing their rights under this Agreement (including without limitation its
rights under Section 8).

          Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the Guarantors,
the Initial Purchasers, the Initial Purchasers' respective directors and
officers, any controlling persons referred to herein, the directors of the
Company and the Guarantors and their respective successors and assigns, all as
and to the extent provided in this Agreement, and no other person shall acquire
or have any right under or by virtue of this Agreement.  The term "successors
and assigns" shall not include a purchaser of any of the Series A Notes from the
Initial Purchasers merely because of such purchase.

          This Agreement shall be governed and construed in accordance with the
laws of the State of New York.

          This Agreement may be signed in various counterparts which together
shall constitute one and the same instrument.

          Please confirm that the foregoing correctly sets forth the agreement
among the Company, the Guarantors and the Initial Purchasers.
