DONALDSON, LUFKIN & JENRETTE 
SECURITIES CORPORATION 
277 Park Avenue 
New York, New York 10172

Dear Sirs:

            Phase Metrics, Inc., a Delaware corporation (the "COMPANY"),
proposes to issue and sell to Donaldson, Lufkin & Jenrette Securities
Corporation (the "INITIAL PURCHASER") an aggregate of $110,000,000 in principal
amount of its 10 3/4% Senior Notes due 2005 (the "SENIOR NOTES"), subject to the
terms and conditions set forth herein. The Senior Notes are to be issued
pursuant to the provisions of an indenture (the "INDENTURE"), to be dated as of
the Closing Date (as defined below), among the Company, the Guarantors (as
defined below) and State Street Bank and Trust Company of California, N.A., as
trustee (the "TRUSTEE"). The Senior Notes and the New Senior Notes (as defined
below) issuable in exchange therefor are collectively referred to herein as the
"NOTES." The Notes will be guaranteed (the "SUBSIDIARY GUARANTEES") by each of
the entities listed on Schedule A, hereto (each, a "GUARANTOR" and collectively
the "GUARANTORS"). Capitalized terms used but not defined herein shall have the
meanings given to such terms in the Indenture.

            1 OFFERING MEMORANDUM. The Senior Notes will be offered and sold to
the Initial Purchaser pursuant to one or more exemptions from the registration
requirements under the Securities Act of 1933, as amended (the "ACT"). The
Company and the Guarantors have prepared a preliminary offering memorandum,
dated December 31, 1997 (the "PRELIMINARY OFFERING MEMORANDUM") and a final
offering memorandum, dated January 23, 1998 (the "OFFERING MEMORANDUM"),
relating to the Senior Notes and the Subsidiary Guarantees.

                                      -1-

            Upon original issuance thereof, and until such time as the same is
no longer required pursuant to the Indenture, the Senior Notes (and all
securities issued in exchange therefor, in substitution thereof or upon
conversion thereof) shall bear the following legend:

            "THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE
      U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
      ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
      WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
      PERSONS, EXCEPT AS SET FORTH IN THE SECOND SENTENCE HEREOF. BY ITS
      ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER (1)
      REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
      RULE 144A UNDER THE SECURITIES ACT)(A "QIB"), (B) IT IS ACQUIRING THIS
      NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE
      SECURITIES ACT OR (C) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS
      DEFINED IN RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D UNDER THE
      SECURITIES ACT (AN "IAI"), (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE
      TRANSFER THIS NOTE EXCEPT (A) TO THE COMPANY OR ANY OF ITS SUBSIDIARIES,
      (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QIB PURCHASING
      FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN A TRANSACTION MEETING
      THE REQUIREMENTS OF RULE 144A, (C) IN AN OFFSHORE TRANSACTION MEETING THE
      REQUIREMENTS OF RULE 903 OR 904 OF THE SECURITIES ACT, (D) IN A
      TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT,
      (E) TO AN IAI THAT, PRIOR TO SUCH TRANSFER, FURNISHES THE TRUSTEE A SIGNED
      LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
      TRANSFER OF THIS NOTE (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE)
      AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF
      NOTES LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY
      THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (F) IN
      ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
      THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE
      COMPANY) OR (G) 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 (3) AGREES
      THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST
      HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.
      AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND "UNITED STATES" HAVE

                                      -2-

      THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE
      SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE
      TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE
      FOREGOING."

            2 AGREEMENTS TO SELL AND PURCHASE. On the basis of the
representations, warranties and covenants contained in this Agreement, and
subject to the terms and conditions contained herein, the Company agrees to
issue and sell to the Initial Purchaser, and the Initial Purchaser agrees to
purchase from the Company, an aggregate principal amount of $110,000,000 of
Senior Notes at a purchase price equal to 96.75% of the principal amount thereof
(the "PURCHASE PRICE").

            3 TERMS OF OFFERING. The Initial Purchaser has advised the Company
that the Initial Purchaser will make offers (the "EXEMPT RESALES") of the Senior
Notes purchased hereunder on the terms set forth in the Offering Memorandum, as
amended or supplemented, solely to (i) persons whom the Initial Purchaser
reasonably believe to be "qualified institutional buyers" as defined in Rule
144A under the Act ("QIBS"), and (ii) to persons permitted to purchase the
Senior Notes in offshore transactions in reliance upon Regulation S under the
Act (each, a "REGULATION S PURCHASER") (such persons specified in clauses (i)
and (ii) being referred to herein as the "ELIGIBLE PURCHASERS"). The Initial 
Purchaser will offer the Senior Notes to Eligible Purchasers initially at a
price equal to 100.0% of the principal amount thereof. Such price may be changed
at any time without notice.

            Holders (including subsequent transferees) of the Senior Notes will
have the registration rights set forth in the registration rights agreement (the
"REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing Date, in substantially
the form of Exhibit A hereto, for so long as such Senior Notes constitute
"TRANSFER RESTRICTED SECURITIES" (as defined in the Registration Rights
Agreement). Pursuant to the Registration Rights Agreement, the Company and the
Guarantors will agree to file with the Securities and Exchange Commission (the
"COMMISSION") under the circumstances set forth therein, (i) a registration
statement under the Act (the "EXCHANGE OFFER REGISTRATION STATEMENT") relating
to the Company's registered 10 3/4% Senior Notes due 2005 (the "NEW SENIOR
NOTES"), to be offered in exchange for the Senior Notes (such offer to exchange
being referred to as the "EXCHANGE OFFER") and the Subsidiary Guarantees thereof
and (ii) a shelf registration statement pursuant to Rule 415 under the Act (the
"SHELF REGISTRATION STATEMENT" and, together with the Exchange Offer
Registration Statement, the "REGISTRATION STATEMENTS") relating to the resale by
certain holders of the Senior Notes and to use its best efforts to cause such
Registration Statements to be declared and remain effective and usable for the
periods specified in the Registration Rights Agreement and to consummate the
Exchange Offer. This Agreement, the Indenture, the Notes, the Subsidiary
Guarantees and the Registration Rights Agreement are hereinafter sometimes
referred to collectively as the "OPERATIVE DOCUMENTS."

            5 AGREEMENTS OF THE COMPANY AND THE GUARANTORS. Each of the Company
and the Guarantors hereby agrees with the Initial Purchaser as follows:

                  (a) To advise the Initial Purchaser promptly and, if requested
by the Initial Purchaser, confirm such advice in writing, (i) of the issuance by
any state securities commission of any stop order suspending the qualification
or exemption from qualification of any Senior Notes for offering or sale in any
jurisdiction designated by the Initial Purchaser 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 shall use its
best efforts to prevent the issuance of any stop order or order suspending the
qualification or exemption of any Senior 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 Senior Notes under any state securities or
Blue Sky laws, the Company shall use its best efforts to obtain the withdrawal
or lifting of such order at the earliest possible time.

                  (b) To furnish the Initial Purchaser and those persons
identified by the Initial Purchaser to the Company as many copies of the
Preliminary Offering Memorandum and the Offering Memorandum, and any amendments
or supplements thereto, as the Initial Purchaser may reasonably request for the
time period specified in Section 5(c). Subject to the Initial Purchaser's
compliance with its 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 

                                      -4-
   6

Memorandum, and any amendments and supplements thereto required pursuant hereto,
by the Initial Purchaser in connection with Exempt Resales.

                  (c) During such period as in the opinion of counsel for the
Initial Purchaser an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchaser and in connection with
market-making activities of the Initial Purchaser for so long as any Senior
Notes are outstanding, (i) not to make any amendment or supplement to the
Offering Memorandum of which the Initial Purchaser shall not previously have
been advised or to which the Initial Purchaser shall reasonably object after
being so advised and (ii) to prepare promptly upon the Initial Purchaser's
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 Purchaser, 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 Purchaser, it is necessary to amend or supplement the Offering
Memorandum to comply with any applicable law, forthwith 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 misleading, or so that such Offering
Memorandum will comply with applicable law, and to furnish to the Initial 
Purchaser and such other persons as the Initial Purchaser may designate such
number of copies thereof as the Initial Purchaser may reasonably request.

                  (e) Prior to the sale of all Senior Notes pursuant to Exempt

jurisdictions as the Initial Purchaser may reasonably 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 relating to the Preliminary Offering Memorandum, the Offering
Memorandum or Exempt Resales, in any jurisdiction in which it is not now so
subject.

                  (f) So long as the Notes are outstanding, (i) to mail and make

consolidated balance sheet, a consolidated statement of operations, a

Guarantors is listed and such other publicly available information concerning
the Company and/or its subsidiaries as the Initial Purchaser may reasonably
request.

                  (h) So long as any of the Senior Notes remain outstanding and

authority to carry on its business as described in the Preliminary Offering
Memorandum and the Offering Memorandum and to own, lease and operate its
properties, and each is duly qualified and is in good standing as a foreign
corporation authorized to do business in each jurisdiction in which the nature
of its business or its ownership or leasing of property requires such

delivered by the Company and each of the Guarantors.

                  (f) The Indenture has been duly authorized by the Company and
each of the Guarantors and, on the Closing Date, will have been validly executed
and delivered by the Company and each of the Guarantors. When the Indenture has
been duly executed and delivered by the Company and each of the Guarantors, the

its terms except as (i) the enforceability thereof may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and (ii) rights
of acceleration and the availability of equitable remedies may be limited by
equitable principles of general applicability. On the Closing Date, the
Indenture will conform in all material respects to the requirements of the Trust
Indenture Act of 1939, as amended (the "TIA" or"TRUST INDENTURE ACT"), and the
rules and regulations of the Commission applicable to an indenture which is

the Senior Notes have been issued, executed and authenticated in accordance with
the provisions of the Indenture and delivered to and paid for by the Initial 
Purchaser in accordance with the terms of this Agreement, the Senior Notes 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
(i) the enforceability thereof may be limited by bankruptcy, insolvency or
similar laws affecting creditors' rights generally and (ii) rights of
acceleration and the availability of equitable remedies may be limited by

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 restricted period, it will not cause any advertisement with respect
to the Senior 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 Senior Notes, except such advertisements as 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 Senior Notes by it to any distributor, dealer or
person receiving a selling concession, fee or other remuneration during the
40-day restricted period referred to in Rule 903(c)(3) 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 Senior 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 Senior 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 must
      deliver a notice to substantially the foregoing effect. Terms used above
      have the meanings assigned to them in Regulation S."

                  (j) Such Initial Purchaser agrees that the Senior Notes
offered and sold in reliance on Regulation S will be represented upon issuance
by a global security that may not be exchanged for definitive securities until
the expiration of the 40-day restricted period referred to in Rule 903(c)(3) of
the Act and only upon certification of beneficial ownership of such Senior Notes
by non-U.S. persons or U.S. persons who purchased such Senior Notes in
transactions that were exempt from the registration requirements of the Act.

                  The 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 the 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 Purchaser, its directors,
its 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 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 (who becomes a holder) of Senior 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 the 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,
provided by the Company to the Initial Purchaser 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 and liabilities and judgements
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 Final Offering Memorandum..

                  (b) The Initial Purchaser 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 the
Initial Purchaser furnished in writing to the Company by the Initial Purchaser
expressly for use in the Preliminary Offering Memorandum or the Offering
Memorandum.

                  (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 which indemnity may be
sought pursuant to both Sections 8(a) 

                                      -20-
   22

and 8(b), the Initial Purchaser 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 fees and expenses of such counsel,
except as provided below, shall be at the expense of the Initial Purchaser). 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 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 (20) 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 Purchaser on the
other hand from the offering of the Senior Notes or (ii) if the 

                                      -21-
   23


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 Purchaser, 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 Purchaser, on the other hand, shall
be deemed to be in the same proportion as the total net proceeds from the
offering of the Senior Notes (after underwriting discounts and commissions, but
before deducting expenses) received by the Company, and the total discounts and
commissions received by the Initial Purchaser bear to the total price to
investors of the Senior 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 Purchaser, 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 Purchaser, 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 Purchaser
agree that it would not be just and equitable if contribution pursuant to this
Section 8(d) were determined by pro rata allocation 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 Purchaser shall not be required to contribute any
amount in excess of the amount by which the total discounts and commissions
received by such Initial Purchaser exceeds the amount of any damages which the
Initial Purchaser has 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.

                  (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 Purchaser to purchase the Senior Notes under this Agreement are
subject to the satisfaction of each of the following conditions:


                                      -22-
   24



                  (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) On or after the date hereof, (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 of the Company or any Guarantor or 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 adverse 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 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 involving a prospective change in 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 involving a prospective change in 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
Senior Notes on the terms and in the manner contemplated in the Offering
Memorandum.

                  (d) You shall have received on the Closing Date a certificate
dated the Closing Date, signed by the President and the Chief Financial Officer
of the Company and each of the Guarantors, confirming the matters set forth in
Sections 6(y), 9(a) and 9(b) and stating 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 Purchaser), dated the Closing
Date, of Brobeck, Phleger & Harrison, LLP, counsel for the Company and the
Guarantors, to the effect that:

                  qualified and is in good standing as a foreign corporation

                  nature of its business or its ownership or leasing of property
                  requires such qualification, except where the failure to be so
                  qualified would not have a Material Adverse Effect;

                        (iii) all the outstanding shares of capital stock of the
                  Company have been duly authorized and validly issued and are
                  fully paid, non-assessable and, to such counsel's knowledge,

                  governmental body or agency (except such as may be
                  required under the securities or Blue Sky laws of the various
                  states), (ii) conflict with or constitute a breach of any of
                  the terms or provisions of, or a default under, the charter or
                  by-laws of the Company or any of its subsidiaries or any
                  indenture, loan agreement, mortgage, lease or other agreement
                  or instrument that is material to the Company and its
                  subsidiaries, taken as a whole (as identified by the Company
                  to such counsel in a certificate to be attached to the
                  opinion) 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 (collectively, the
                  "Reviewed Agreements"), (iii) violate or conflict with any

                  its subsidiaries or their respective property or (iv) result
                  in the imposition or creation of (or the obligation to create
                  or impose) a Lien under any Reviewed Agreement.

                  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 could reasonably be expected to result,
                  singly or in the aggregate, in a Material Adverse Effect on
                  the ability of the Company and the Guarantors to perform their
                  respective obligations hereunder and under the Senior Notes
                  and the other documents executed in connection herewith and

                  offering and sale of the Senior Notes and the application of
                  the net proceeds thereof as described in the Offering

                  respects with the requirements of the TIA, and the rules and
                  regulations of the Commission applicable to an indenture which

                  Regulation S Purchaser, (ii) the accuracy of, and 

                                      -26-

                  agreements contained in Section 7 of this Agreement and (iii)
                  the accuracy of the representations of the Company and the

                  (ff) and Sections 7(h), (i) and (j) of this Agreement.

                        (xviii) such counsel has no reason to believe that, as
                  of the date of the Offering Memorandum or as of the Closing
                  Date, the Offering Memorandum, as amended or supplemented, if
                  applicable (except for the financial statements and other
                  financial data included therein, as to which such counsel need
                  not express any belief) contains any untrue statement of a
                  material fact or omits to state a material fact necessary in
                  order to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading.

                  The opinion of Brobeck, Phleger & Harrison, 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. In giving such opinion with respect
to the matters covered by Section 9(e)(xvii), such counsel for the Company may
state that their opinion and belief are based upon their participation in the
