ITEM 1.     SECURITY AND ISSUER.
            --------------------

     This statement on Schedule 13D (the "Statement") relates to the acquisition
of shares of the common stock, $.10 par value (the "Common Stock") of
TIE/communications, Inc. (the "Issuer"), a Delaware corporation, whose principal
executive offices are located at 8500 West 110th Street, Overland Park, Kansas
66210 .

ITEM 2.     IDENTITY AND BACKGROUND.
            ------------------------

     This Statement is being filed by TIE Acquisition Co. ("Acquisition") and
Paul H. Pfleger, a United States citizen and sole stockholder of Acquisition.
Acquisition is a Delaware corporation formed for the principal purpose of
acquiring all of the outstanding shares of Common Stock of Issuer pursuant to
that certain Agreement and Plan of Merger, dated as of September 5, 1995, by and
among Acquisition, TIE Merger Co. and Issuer (the "Merger Agreement").  A copy
of the Merger Agreement is filed as an Exhibit to this filing and is hereby
incorporated herein by reference.  The address of Acquisition's principal
business and principal office is: 1201 Third Avenue, Suite 5400, Seattle,
Washington 98101.  The name, business address, present principal occupation or
employment and the name, principal business and address of any corporation or
other organization in which such employment is conducted with respect to Mr.
Pfleger and each of the other executive officers and directors of Acquisition
are set forth in Exhibit 7(i) to this Statement and are incorporated herein by
reference.  Neither Acquisition, Mr. Pfleger, nor, to the best knowledge of
Acquisition, any of the persons listed in Exhibit 7(i), has been convicted in
any criminal proceeding during the past five years.  Neither Acquisition, Mr.
Pfleger, nor, to the best knowledge of Acquisition, any of the persons listed in
Exhibit 7(i), has, during the last five years, been party to any civil
proceedings of a judicial or administrative body of competent jurisdiction which
resulted in a judgment, decree or final order enjoining future violations of, or
prohibiting on mandatory activities subject to, Federal or State securities laws
or finding any violation with respect to such laws.
 
ITEM 3.     SOURCE AND AMOUNT OF FUNDS FOR OTHER CONSIDERATION.
            ---------------------------------------------------

     All of the securities which are the subject of this Statement were acquired
by Acquisition pursuant to that certain Offer to Purchase, dated September 12,
1995, as supplemented by that certain Supplement to Offer to Purchase, dated
October 11, 1995, to the shareholders of Issuer (the "Tender Offer"). The
aggregate purchase price of the shares purchased by Acquisition pursuant to the
Tender Offer was $32,246,448.20 and was obtained as follows: (i) approximately
$8 million was provided from working capital of Acquisition, (ii) $20 million
was provided from borrowings pursuant to that certain Loan Agreement, dated
October 18, 1995, by and between Acquisition and NationsBank of Georgia N.A.,
and (iii) an additional $10 million was provided from funds borrowed by
Acquisition from TIE Investment Inc., a Washington corporation and affiliate of
Acquisition, such funds having been borrowed by TIE Investment Inc. pursuant to
that certain Term Loan Agreement, dated as of October 18, 1995, by and between
TIE Investment Inc., Acquisition and Kellett Investment Corporation, as co-
lender, and Creditanstalt Corporate Finance, Inc. as co-lender and collateral
agent.

ITEM 4.     PURPOSE OF TRANSACTION.
            -----------------------

     The acquisition of the securities which are the subject of this Statement
is the first step in the acquisition by Acquisition of all of the outstanding
Common Stock of Issuer pursuant to the Merger Agreement. As set forth in the
Merger Agreement, following the consummation of the Tender Offer Acquisition
intends to cause TIE Merger Co., a wholly-owned subsidiary of Acquisition, to be
merged with and into Issuer, whereupon each shareholder of Issuer (other than
Acquisition) shall by virtue of the merger and without any other action have
their shares of Common Stock converted into the right to receive $8.60 per
share, the same per share consideration offered in the Tender Offer. Subject to
the terms and conditions set forth therein, the Merger Agreement provides for
the merger to be consummated on or before December 15, 1995. As set forth in the
Merger Agreement and as described in the Tender Offer Statement on Schedule 14D-
1 filed by Acquisition with the United States Securities and Exchange Commission
in connection with the Tender Offer, as amended (the "Schedule 14D-1"), upon
consummation of the Tender Offer five directors of Issuer tendered their
resignations from the board of directors of Issuer and on October 23, 1995 the
remaining members of the board of directors filled the vacancies on the board of
directors credited by such resignations by electing to the board of directors
the nominees named by Acquisition in the Schedule 14D-1. In addition, the board
of directors of the Issuer
<PAGE>
 
named Charles B. McNamee to the position of Chief Executive Officer and
President of Issuer, replacing George N. Benjamin, III .  Following the merger,
Acquisition intends to promptly cause shares of the surviving corporation to be
delisted from the American Stock Exchange, Inc. and to terminate the
registration of such shares pursuant to Section 12(g)(4) of the Securities
Exchange Act of 1934, as amended.

     Except as indicated in this filing, the Merger Agreement and the Schedule
14D-1, Acquisition does not have any present plans or proposals which relate to
or would result in an extraordinary corporate transaction, such as a merger,
reorganization or liquidation involving TIE or any of its subsidiaries, a sale
or transfer of a material amount of assets of TIE or any of its subsidiaries or
any change in TIE's capitalization or dividend policy or any other material
changes in TIE's corporate structure or business.

ITEM 5.     INTEREST IN THE SECURITIES OF THE ISSUER.
            -----------------------------------------

     (a) Acquisition beneficially owns in the aggregate 3,749,587 shares or 94.2
percent of the outstanding Common Stock of the Issuer.  As the sole stockholder
of Acquisition, Mr. Pfleger is deemed to beneficially own all shares of Common
Stock of the Issuer owned by Acquisition.

     (b) Acquisition possesses sole voting and dispositive power with respect to
all 3,749,587 shares of Common Stock of the Issuer.  Except as described herein,
Acquisition does not share with any other person voting or dispositive power
with respect to any shares of Common Stock of the Issuer.  As the sole
stockholder of Acquisition, Mr. Pfleger is deemed to have sole power to direct
the vote or sole power to direct the disposition of all shares of Common Stock
of the Issuer owned by Acquisition.

     (c) Not applicable.

     (d) Not applicable.

     (e) Not applicable.

ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
            ------------------------------------------------------------- 
            RESPECT TO SECURITIES OF THE ISSUER.
            -----------------------------------

     Except for the Merger Agreement which is filed as Exhibit 7(ii) to this
Statement and is hereby incorporated by reference, there are no contracts,
arrangements, understandings or relationships between Acquisition or any other
person with respect to any securities of the Issuer required to be disclosed
pursuant to this Item.

ITEM 7.     MATERIAL TO BE FILED AS EXHIBITS.

                          AGREEMENT AND PLAN OF MERGER


     THIS AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of September
5, 1995, is among TIE/communications, Inc., a Delaware corporation (the
"Company"), TIE Acquisition Co., a Delaware corporation ("Parent") and TIE
Merger Co., a Delaware corporation and wholly-owned subsidiary of Parent
("Acquisition").

     WHEREAS, the Board of Directors of the Company (the "Board") desires to
optimize stockholder value and has been evaluating alternatives, including the
continuation of the Company's current business strategies, the implementation of
strategic alliances with one or more synergistic parties or a sale or similar
disposition of the Company;

     WHEREAS, various potential purchasers have submitted proposals to acquire
the Company and these proposals have been considered and evaluated by the Board,
with the advice and assistance of its legal and financial advisors;

     WHEREAS, the Board has determined that it is in the best interests of the
Company's stockholders for the Company to enter into this Agreement with Parent
and Acquisition, providing for the acquisition of the Company upon the terms and
subject to the conditions set forth herein;

     WHEREAS, subject to the terms and conditions of this Agreement, and in
furtherance hereof, Parent shall make a tender offer (the "Offer") to acquire
all of the outstanding shares of common stock, par value $.10 per share, of the
Company (the "Shares") for a cash amount of $8.60 per share net to the seller
(such amount, or any greater amount per Share paid pursuant to the Offer, being
hereinafter referred to as the "Per Share Amount");

     WHEREAS, the Board has, in light of and subject to the terms and conditions
set forth herein, (i) determined that the Offer and the Merger (as hereinafter
defined), taken together, is fair to and in the best interests of the
stockholders of the Company and (ii) approved and adopted this Agreement and the
transactions contemplated hereby (including, but not limited to, the Offer) and
resolved to recommend acceptance of the Offer and, if required by applicable
law, approval and adoption of this Agreement and the Merger by the stockholders
of the Company;

     WHEREAS, subject to the terms and conditions of this Agreement and also in
furtherance of such acquisition, the Managing Board of Parent and the Board of
Directors of Acquisition have each approved the merger (the "Merger") of
Acquisition with and into the Company following the Offer in accordance with the
General Corporation Law of the State of Delaware (the "Delaware Law"), pursuant
to which the holders of Shares (other than

Acquisition, Parent and any direct or indirect subsidiary of Parent or
Acquisition) shall receive the Per Share Amount; and

     WHEREAS, Parent has received the written commitment of Marmon Holdings,
Inc. ("Marmon") and The Pritzker Family Philanthropic Fund to tender the
respective Shares owned by each of them pursuant to the Offer, and not to
withdraw such Shares from such tender, and
<PAGE>
 
each of Marmon Holdings, Inc. and The Pritzker Family Philanthropic Fund has
granted to Parent an irrevocable option to purchase and an irrevocable proxy
with respect to the respective Shares owned or hereafter acquired by each of
them, all pursuant to and subject to the conditions of that certain Stockholders
Option Agreement of even date herewith (the "Stockholders Option Agreement").

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, the
Company, Parent and Acquisition hereby agree as follows.

                                   ARTICLE I.

                                   THE OFFER

     SECTION 1.01  The Offer.  (a)  Provided that this Agreement shall not have
                   ---------                                                   
been terminated in accordance with Section 8.01 hereof and none of the events
set forth in Annex A hereto shall have occurred or be existing, Parent shall
commence the Offer as promptly as reasonably practicable after the date hereof,
but in no event later than September 12, 1995.  The obligation of Parent to
accept for payment and to pay for Shares tendered pursuant to the Offer shall be
subject to the condition that at least 2,986,004 Shares (or such greater number
of Shares as equals 75% of the Shares then outstanding) shall have been validly
tendered and not withdrawn prior to the expiration of the Offer (the "Minimum
Tender Condition") and shall also be subject to the satisfaction of the other
conditions set forth in Annex A hereto.  Subject to the terms and conditions of
the Offer (including the Minimum Tender Condition), Parent shall pay for Shares
which have been validly tendered and not withdrawn pursuant to the Offer as
promptly as reasonably practicable after expiration of the Offer.  Parent
expressly reserves the right to increase the price per Share payable in the
Offer or to make any other changes in the terms and conditions of the Offer;
provided that, unless approved by the Board in writing, no change will be made
that decreases the price per Share payable in the Offer, changes the form of
consideration payable in the Offer, adds additional conditions to the Offer,
decreases the number of Shares being tendered for in the Offer, or makes any
change in the terms and conditions of the Offer which is inconsistent with the
third sentence of this Section 1.01(a) or which is otherwise materially adverse
to holders of Shares.  It is agreed that the conditions set forth in Annex A
hereto are for the benefit of Parent and may be asserted by Parent or, subject
to the preceding sentence, may be waived by Parent, in whole or in part at any
time and from time to time, in its sole discretion.  The Per Share Amount,
subject to applicable withholding taxes, shall be paid net to the seller in
cash, upon the terms and subject to the conditions of the Offer.

     (b) As soon as reasonably practicable on the date of commencement of the
Offer, Parent and Acquisition shall file with the Securities and Exchange
Commission (the "SEC") (i) a Tender Offer Statement on Schedule 14D-1 (together
with any amendments or supplements thereto, the "Schedule 14D-1") with respect
to the Offer and (ii) if required, a Rule 13E-3 Transaction Statement (the
"Schedule 13E-3") with respect to the execution and delivery of the Stockholders
Option Agreement and the Offer.  The Schedule 14D-1 shall contain or shall
incorporate by reference an offer to purchase and a form of the related letter
of transmittal and any related summary advertisement (together with all
supplements or amendments thereto and the Schedule 14D-1, the "Offer
Documents").  The Offer Documents and Schedule 13E-3 will

                                       2
<PAGE>
 
comply in all material respects with the provisions of applicable federal
securities laws and, on the date filed with the SEC and on the date first
published, sent or given to the Company's stockholders, shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation is made by Parent or Acquisition with respect to
information supplied by the Company for inclusion in the Offer Documents or
Schedule 13E-3.  Parent, Acquisition and the Company each agrees promptly to
correct any information provided by it for use in the Offer Documents and
Schedule 13E-3 if and to the extent that it shall have become false or
misleading in any material respect and Parent and Acquisition each further
agrees to take all steps necessary to cause the Offer Documents and Schedule
13E-3 as so corrected to be filed with the SEC and to be disseminated to holders
of Shares, in each case as and to the extent required by applicable federal
securities laws.  Parent and Acquisition agree to provide the Company and its
counsel in writing any comments Parent, Acquisition or their counsel may receive
from the SEC or its Staff with respect to the Offer Documents promptly after the
receipt of such comments.

     (c) The Company shall prepare and file with the SEC, subject to the prior
approval of Acquisition (which approval shall not be unreasonably withheld), if
necessary, as soon as practicable after the expiration of the Offer, a proxy or
information statement (the "Proxy Statement") and such other documents relating
to the Merger as required by the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and the rules and regulations thereunder, and the Company
shall prepare or shall assist Parent and Acquisition in preparing, as the case
may be, any other filings required under the Exchange Act, the Securities Act of
1933, as amended (the "Securities Act"), or any other federal or state
securities laws relating to the Offer, the Merger and the transactions
contemplated herein (the "Other Filings").  The Company shall obtain and furnish
the information required to be included in the Proxy Statement and shall,
subject to the prior approval of Acquisition (which approval shall not be
unreasonably withheld), respond promptly to any comments made by the SEC with
respect to the Proxy Statement and cause the Proxy Statement to be mailed to the
Company's stockholders at the earliest reasonably practicable date.

     SECTION 1.02  Company Action.  (a)  The Company hereby approves of and
                   --------------                                          
consents to the Offer and represents and warrants that the Board, at a meeting
duly called and held, has in light of and subject to the terms and conditions
set forth herein, (i) determined that this Agreement and the transactions
contemplated hereby, including the Offer and the Merger, taken together, are
fair to and in the best interests of the stockholders of the Company, (ii)
approved and adopted this Agreement and the transactions contemplated hereby,
including the Offer and the Merger, which approval constitutes approval for
purposes of Section 203(a)(1) of the Delaware Law of the Offer, the execution,
delivery and performance of the Stockholders Option Agreement by and among
Acquisition and the stockholders who are parties thereto and the Merger, and
(iii) resolved to recommend that the stockholders of the Company accept the
Offer, tender their Shares thereunder to Acquisition and, if required by
applicable law, approve and adopt this Agreement and the Merger; provided,
                                                                 -------- 
however, that such recommendation may be withdrawn, modified or amended to the
- -------                                                                       
extent that the members of the Board, by a majority vote, determine in good
faith (upon advice of counsel) that they are required to do so in the exercise
of their fiduciary duties.  The Company hereby consents to the inclusion in the
Offer Documents of the recommendation of the Board described in the immediately
preceding sentence.

                                       3
<PAGE>
 
     (b) The Company hereby agrees to file with the SEC as promptly as
reasonably practicable on the date of the commencement of the Offer, a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with any
amendments or supplements thereto, the "Schedule 14D-9") containing the
recommendations described in Section 1.02(a) hereof and to disseminate the
Schedule 14D-9 to the extent required by Rule 14e-2 promulgated under the
Exchange Act and any other applicable federal securities laws.  The Schedule
14D-9 will comply in all material respects with the provisions of applicable
federal securities laws and, on the date filed with the SEC, shall not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation is made by the Company with respect to
information supplied by Parent or Acquisition for inclusion in the Schedule 14D-
9.  Parent and its counsel shall be given the opportunity to review the Schedule
14D-9 prior to the filing thereof with the SEC.  The Company, Parent and
Acquisition each agrees promptly to correct any information provided by it for
use in the Schedule 14D-9 and to the extent that it shall have become false or
misleading in any material respect the Company further agrees to take all steps
necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC
and disseminated to the holders of Shares, as and to the extent required by
applicable federal securities laws.  The Company agrees to provide to
Acquisition and its counsel in writing any comments the Company or its counsel
may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after receipt of such comments.  Notwithstanding anything contained in
this Section 1.02(b), but subject to Section 8.03 hereof, if the members of the
Board by majority vote determine in good faith (upon advice of counsel) that it
is required in the exercise of their fiduciary duties to withdraw, modify or
amend the recommendation of the Board, such withdrawal, modification or
amendment shall not constitute a breach of this Agreement.

     (c) In connection with the Offer, the Company will promptly furnish Parent
with such information, including current lists of the stockholders of the
Company, mailing labels and lists of security positions and shall furnish Parent
with such additional information and assistance (including, without limitation,
updated lists of stockholders, mailing labels and lists of securities positions)
as Parent or its agents may reasonably request in communicating the Offer to the
record and beneficial holders of Shares.  Subject to the requirements of
applicable law, and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Merger,
Parent and its affiliates and associates shall hold in confidence the
information contained in any such labels, listings and files, will use such
information only in connection with the Offer and the Merger, and, if this
Agreement shall be terminated, will deliver to the Company all copies of such
information then in their possession.

     SECTION 1.03  Boards of Directors and Committees; Section 14(f).  (a)
                   -------------------------------------------------       
Effective upon the purchase by Parent of Shares pursuant to the Offer and from
time to time thereafter, Parent shall be entitled to designate up to such number
of directors, rounded up to the next whole number, on the Board as will give
Parent representation on the Board equal to the product of the number of
directors on the Board and the percentage that such number of Shares so
purchased bears to the total number of outstanding Shares, and the Company shall
take all actions necessary to cause Parent's designees to be elected or
appointed to the Company's Board; provided, however, that prior to the Effective
                                  --------  -------                             
Time (as hereinafter defined), the Board shall always have at least three (3)
members who are neither officers of the Company nor designees, stockholders,
affiliates or associates of Parent, Acquisition or, unless such designee is
consented

                                       4
<PAGE>
 
to by Parent (which consent shall not be unreasonably withheld), any party to
the Stockholders Option Agreement (the "Independent Directors").  At such times
the Company will use its best efforts to cause persons designated by Parent to
constitute the same percentage as is on the Board of (i) each committee of the
Board (other than any committee of the Board established to take action under
this Agreement), (ii) each board of directors of each subsidiary of the Company,
and (iii) each committee of each such board.

     (b) The Company's obligations to appoint designees to the Board shall be
subject to Section 14(f) of the Exchange Act ("Section 14(f)") and Rule 14f-1
promulgated thereunder ("Rule 14f-1").  The Company shall promptly take all
actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill
its obligations under this Section 1.03 and shall include in the Schedule 14D-9
or the Schedule 14D-1 such information with respect to the Company and its
officers and directors as is required under Section 14(f) and Rule 14f-1.
Parent or Acquisition will supply to the Company in writing and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by Section 14(f) and Rule
14f-1.

     (c) Following the election or appointment of Acquisition's designees
pursuant to this Section 1.03 and prior to the Effective Time (as hereinafter
defined), (i) any amendment to this Agreement which (A) decreases the price per
Share payable hereunder, (B) changes the form of consideration payable
hereunder, or (C) makes any change in the terms and conditions of this Agreement
which is otherwise materially adverse to holders of Shares, (ii) any extension
by the Company of the time for the performance of any of the obligations or
other acts of Parent or Acquisition or the waiver of any of the Company's rights
hereunder, and (iii) any termination of the Agreement, will require the
concurrence of a majority of the Independent Directors.

                                  ARTICLE II.

                                   THE MERGER

subject to the satisfaction or waiver of the conditions of this Agreement and
the Delaware Law, Acquisition shall be merged with and into the Company.

VII, the parties hereto shall file a certificate of merger or certificate of
ownership and merger with the Secretary of State of the State of Delaware, and
take all such other and further actions as may be required by law to make the
Merger effective.  The Merger shall become effective at such time as the
certificate of merger or certificate of ownership and merger is duly filed with

     SECTION 2.03  Effects of the Merger.  The Merger shall have the effects set
                   ---------------------

the Effective Time shall be the officers of the Surviving Corporation and will
hold office from the Effective Time until their respective successors are duly
elected or appointed and qualified in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation.

                        -----------------                                   
Agreement to the contrary, Shares outstanding immediately prior to the Effective
Time and held by a holder who has not voted in favor of the Merger or consented
thereto in writing and who shall have demanded properly in writing appraisal for
such Shares in accordance with Section 262 of the Delaware Law (collectively,
the "Dissenting Shares") shall not be converted into a right to receive the Per
Share Amount unless such holder fails to perfect or withdraws or otherwise loses
his right to appraisal under the Delaware Law.  Such stockholders shall be
entitled to receive payment of the appraised value of such Shares in accordance
with Section 262 of the Delaware Law, except all Dissenting Shares held by
stockholders who have failed to perfect or who effectively shall have withdrawn
or lost their right to appraisal of such Dissenting Shares shall be deemed to
have been converted as of the Effective Time into a right to receive the Per
Share Amount without interest thereon, upon surrender, in the manner provided in
Section 3.02 hereof, of the certificate(s) that formerly evidenced such Shares.
The Company shall provide Parent (i) prompt notice of and copies of any demands
received by the Company for appraisal of Shares, withdrawals of such demands,
and any other instruments served pursuant to the Delaware Law and received by
the Company and, (ii) prior to the Effective Time, the right to direct all
negotiations and proceedings with respect to such demands.  Prior to the
Effective Time, the Company shall not, except with the prior written consent of
Parent, make any payment with respect to, or settle or offer to settle, any such
demands.

          SECTION 3.02  Exchange of Certificates.  (a)  Prior to the Effective
                        ------------------------                              
Time, a bank or trust company shall be designated by Parent which shall be
reasonably acceptable to the Company (the "Exchange Agent") to act as exchange
agent in effecting the exchange of the Per Share Amount for certificates (the
"Certificates") that, immediately prior to the Effective Time, evidenced Shares
entitled to payment pursuant to Section 2.07(a) hereof.  As soon as practicable
after the Effective Time, the Surviving Corporation shall instruct the Exchange
Agent to mail or otherwise deliver to each record holder, immediately prior to
the Effective Time, of an outstanding Certificate or Certificates which
immediately prior to the Effective Time evidenced Shares, a letter of
transmittal and instructions for use in effecting the surrender of the
Certificates for payment thereof (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery to the Exchange Agent and shall be in such form and have such
other provisions as Parent may reasonably specify).  Upon the surrender of each
such Certificate, together with a duly executed letter of transmittal and such
other customary documents as may be required pursuant to the instructions, the
Exchange Agent shall pay the holder of such Certificate an amount in cash equal
to the Per Share Amount multiplied by the number of Shares formerly evidenced by
such Certificate, in exchange therefor, and such Certificate shall forthwith be
cancelled.  Until so surrendered and exchanged, each such Certificate (other
than Certificates representing Dissenting Shares or Shares held by Parent,
Acquisition or the Company, or any direct or indirect subsidiary thereof) shall
represent solely the right to receive the Per Share Amount multiplied by the
number of Shares formerly evidenced by such Certificate.  No interest shall be
paid or accrue on the Per Share Amount.  If the Per Share Amount (or any portion
thereof) is to be delivered to any person other than the person in whose name
the Certificate evidencing Shares surrendered in exchange therefor is
registered, it shall be a condition to such exchange that the Certificate so
surrendered shall be

                                       7
<PAGE>
 
properly endorsed or otherwise be in proper form for transfer and that the
person requesting such exchange shall pay to the Exchange Agent any transfer or
other taxes required by reason of the payment of the Per Share Amount to a
person other than the registered holder of the Certificate surrendered, or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable.  From and after the Effective Time, the holders of
Certificates shall cease to have any rights with respect to Shares, except as
otherwise provided herein or by law.

          (b) At or before the Effective Time, Parent shall (or shall cause
Acquisition to) deposit in trust with the Exchange Agent, in immediately
available funds, the aggregate Per Share Amount to which holders of Shares shall
be entitled at the Effective Time pursuant to Section 2.07(a) hereof (the
"Fund").  At the direction of Parent, the Exchange Agent may invest portions of
the Fund in any of (i) readily marketable obligations of the United States or
any agent or instrumentality thereof or obligations unconditionally guaranteed
by the government of the United States; (ii) certificates of deposit of or time
deposits with any commercial bank (including the Exchange Agent) that has
combined capital and surplus of at least $500,000,000; (iii) commercial paper
issued by any corporation which is rated at least "P-1" by Moody's Investors
Service, Inc. or "A-1" by Standard & Poor's Corporation; or (iv) money market
mutual funds investing in obligations of the type described in subclauses (i),
(ii) or (iii) hereof.  Any earnings resulting from, or interest or income
produced by, such investments shall be paid to the Surviving Corporation as and
when requested by the Surviving Corporation.

          (c) Promptly following the date which is one (1) year after the
Effective Time, the Exchange Agent shall deliver to the Surviving Corporation
all cash and other documents in its possession relating to the transactions
described in this Agreement, and the Exchange Agent's duties shall terminate.
Thereafter, each holder of a Certificate formerly evidencing a Share may
surrender such Certificate to the Surviving Corporation and (subject to
applicable abandoned property, escheat and similar laws) receive in exchange
therefor the Per Share Amount multiplied by the number of Shares formerly
evidenced by such Certificate, without any interest or dividends thereon.

          (d) At and after the Effective Time, the stock transfer records of the
Company shall be closed, and there shall be no transfers on the stock transfer
books of the Company of any Shares.  If, after the Effective Time, Certificates
formerly representing Shares are presented to the Surviving Corporation or the
Exchange Agent, they shall be cancelled and exchanged for the Per Share Amount
multiplied by the number of Shares formerly evidenced by such Certificate, as
provided in this Article III, subject to applicable law in the case of
Dissenting Shares.

                                  ARTICLE IV.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company represents and warrants to Parent and Acquisition as
follows:

          SECTION 4.01  Organization and Qualification.  (a)  The Company is a
                        ------------------------------                        
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has all requisite corporate power and authority and
all necessary governmental approvals to own, lease and operate its properties
and to carry on its business as now being conducted, except

                                       8
<PAGE>
 
where the failure to be so organized, existing or in good standing or to have
such power, authority and governmental approvals would not have a Material
Adverse Effect (as hereinafter defined).  The Company has heretofore delivered
to Parent or Acquisition accurate and complete copies of the certificate of
incorporation and by-laws of the Company, as currently in effect.  When used in
connection with the Company or any of its subsidiaries, the term "Material
Adverse Effect" means any change or effect that, individually or when taken
together with all other such changes or effects, is or would reasonably be
likely to be materially adverse to the business, assets, results of operations
or financial condition of the Company and its subsidiaries, taken as a whole.
For purposes of this Agreement, the term "subsidiary" of the Company shall mean
each corporation or other entity in which the Company owns or controls, directly
or through one or more subsidiaries, 50 percent or more of the stock or other
interests having general voting power in the election of directors or persons
performing similar functions.

          (b) The Company is duly qualified or licensed and in good standing to
do business in each jurisdiction in which the property owned, leased or operated
by it or the nature of the business conducted by it make such qualification or
licensing necessary, except in such jurisdictions where the failure to be so
duly qualified or licensed and in good standing would not, individually or in
the aggregate, have a Material Adverse Effect.

          SECTION 4.02  Subsidiaries.  (a)  The subsidiaries of the Company are
                        ------------                                           
listed on Schedule 4.02 hereto together with, as to each subsidiary, a list
identifying (i) the jurisdiction of incorporation of such subsidiary, (ii) each
jurisdiction in which such subsidiary is qualified to conduct business, (iii)
each jurisdiction in which such subsidiary has an office or conducts business.
Except as set forth on Schedule 4.02 hereto, each subsidiary is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as now being conducted, except where the
failure to be so organized, existing and in good standing or to have such power,
authority and governmental approvals would not, individually or in the
aggregate, have a Material Adverse Effect.  The Company has heretofore delivered
to Parent or Acquisition accurate and complete copies of the certificates of
incorporation and by-laws or equivalent organizational documents of each
subsidiary of the Company, each as currently in effect.  Each subsidiary is duly
qualified or licensed and in good standing to do business in each jurisdiction
in which the property owned, leased or operated by it or the nature of the
business conducted by it make such qualification or licensing necessary, except
in such jurisdictions where the failure to be so duly qualified or licensed and
in good standing would not, individually or in the aggregate, have a Material
Adverse Effect.

          (b) Except as set forth in Schedule 4.02 hereto, the Company is,
directly or indirectly, the record and beneficial owner of all of the
outstanding shares of capital stock of each of its subsidiaries.  Except as set
forth on Schedule 4.02 hereto, each outstanding share of capital stock of each
subsidiary of the Company is duly authorized, validly issued, fully paid and
nonassessable and to the extent owned by the Company or any subsidiary of the
Company is free and clear of any security interest, claim, lien, charge,
encumbrance, pledge, option, right of first refusal, limitation on voting rights
or agreement of any kind.  There are no proxies with respect to any shares of
capital stock of any subsidiary of the Company to the extent owned by the
Company or any subsidiary of the Company, and no equity securities of any of its
subsidiaries are or may become required to be issued by reason of any options,
warrants, rights to subscribe

                                       9
<PAGE>
 
to, calls or commitments of any character whatsoever relating to, or securities
or rights convertible into or exchangeable or exercisable for, shares of any
capital stock of any subsidiary, and there are no contracts, commitments,
undertakings or arrangements by which the Company or any subsidiary is or may be
bound to issue additional shares of its capital stock or securities convertible
into or exchangeable or exercisable for any such shares.  Except as set forth on
Schedule 4.02 hereto or in the SEC Reports (as hereinafter defined), the Company
does not directly or indirectly own any equity or similar interest in, or any
interest convertible into or exchangeable or exercisable for, any equity or
similar interest in, any corporation (other than a subsidiary), partnership,
joint venture or other business association or entity which is material (in
assets, earnings or otherwise) to the Company and its subsidiaries as a whole.

          SECTION 4.03  Capitalization of the Company.  The authorized capital
                        -----------------------------                         
stock of the Company consists solely of 10,000,000 Shares of which, as of July
31, 1995, 3,981,338 Shares were issued and outstanding.  All outstanding Shares
have been duly authorized, validly issued, and are fully paid, nonassessable and
free of preemptive rights.  Except as described above, there are outstanding (i)
no shares of capital stock or other voting securities of the Company, (ii) no
securities of the Company convertible into or exchangeable for shares of capital
stock or voting securities of the Company, and (iii) no options, warrants or
other rights to acquire from the Company, and no obligation of the Company to
issue, any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of the Company.

          SECTION 4.04  Authority Relative to this Agreement; Governmental
                        --------------------------------------------------
Approvals.  The Company has all necessary corporate power and authority to
- ---------                                                                 
execute and deliver this Agreement, to perform its obligations hereunder and to
consummate the transactions contemplated hereby (other than, with respect to the
Merger, the approval and adoption of this Agreement and the Merger by the
stockholders of the Company as required by applicable law and the Company's
Restated Certificate of Incorporation).  The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby have been
duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of the Company are necessary to authorize the
execution, delivery and performance of this Agreement or to consummate the
transactions contemplated hereby (other than, with respect to the Merger, the
approval and adoption of this Agreement and the Merger by the stockholders of
the Company as required by applicable law and the Company's Restated Certificate
of Incorporation).  This Agreement has been duly and validly executed and
delivered by the Company and constitutes the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally, and subject, as to enforceability, to general principles of
equity whether raised at law or in equity.  The Company has taken all
appropriate actions so that the restrictions on business combinations contained
in Section 203 of the Delaware Law will not apply with respect to or as a result
of the Offer, the Merger, or the execution, delivery and performance of this
Agreement or the Stockholders Option Agreement.  Except as set forth on Schedule
4.04 hereto, the execution, delivery and performance by the Company of this
Agreement and the consummation of the Merger by the Company will not require any
consent, approval, authorization, or permit of, or filing with or notification
to, any United States federal or state or foreign governmental body, agency,
official or authority other than (i) the filing of a certificate of merger or a
certificate of ownership and merger in accordance with the Delaware

                                       10
<PAGE>
 
Law; (ii) compliance with any applicable requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"); (iii) compliance
with any applicable requirements of the Exchange Act; and (iv) compliance with
any applicable state securities, takeover or "blue sky" laws; and (v) compliance
with any applicable requirements of the Investment Canada Act of 1985 and the
Competition Act (Canada).  Except for consents, approvals, licenses,
accreditations, permits, franchises, authorizations or orders currently held by
the Company or its subsidiaries, the conduct by the Surviving Corporation of the
business of the Company and its subsidiaries in the same manner as now conducted
by the Company and its subsidiaries requires no consent, approval, license,
accreditation, permit, franchise, authorization or order of or notice or filing
with any domestic or foreign governmental commission, board or other regulatory
body.

          SECTION 4.05  Non-Contravention.  Except as set forth on Schedule 4.05
                        -----------------                                       
hereto, neither the execution and delivery of this Agreement by the Company nor
the consummation of the transactions contemplated hereby nor compliance by the
Company with any of the provisions hereof will (i) violate, conflict with, or
result in a breach of any provision of, or constitute a default (or an event
which, with notice or lapse of time or both, would constitute a default) under,
or result in the loss of a material benefit under, or give to others any right
of termination, amendment, acceleration or cancellation of, or result in a right
of termination or acceleration under, or result in the creation of any mortgage,
pledge, security interest, claim, encumbrance or lien of any kind (a "Lien")
upon any of the properties or assets of the Company or any of its subsidiaries
under any of the terms, conditions or provisions of (x) the certificates or
articles of incorporation or by-laws or similar organizational documents of the
Company or any of its subsidiaries, or (y) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries or any of their respective
properties or assets may be subject, or (ii) subject to compliance with the
statutes and regulations referred to in Section 4.04 hereof, violate any
judgment, ruling, order, writ, injunction, decree, statute, rule or regulation
applicable to the Company, any of its subsidiaries or any of their respective
properties or assets, except, in the case of clause (i) above, for such
violations, conflicts, breaches, defaults, losses, terminations, accelerations
or creations of Liens which would not, individually or in the aggregate, have a
Material Adverse Effect.

          SECTION 4.06  SEC Reports.  The Company has filed all forms, reports
                        -----------                                           
and documents required to be filed with the SEC since July 1, 1991
(collectively, the "SEC Reports"), each of which, as heretofore amended, has
complied in all material respects with all applicable requirements of the
Securities Act and the Exchange Act and the rules and regulations of the
American Stock Exchange, Inc.  As of their respective dates, and except as
disclosed in an amendment to an SEC Report or in a subsequently filed SEC
Report, none of the SEC Reports, including, without limitation, any financial
statements or schedules included therein, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The audited
consolidated financial statements and unaudited consolidated interim financial
statements of the Company included in the SEC Reports were prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods indicated (except as may be noted
therein) and each fairly presents the consolidated financial position of the
Company and its subsidiaries as of the dates thereof and their consolidated
results of operations and changes in financial position for

                                       11
<PAGE>
 
the periods then ended (subject to normal year-end adjustments in the case of
any unaudited interim financial statements).  Except as and to the extent set
forth in the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 1994 (the "1994 10-K"), or in its Quarterly Reports on Form 10-Q
filed since that date, neither the Company nor any subsidiary has any liability
or obligation of any nature whatsoever (whether due or to become due, accrued,
fixed, contingent, liquidated, unliquidated or otherwise) that would be required
by GAAP to be reflected on a consolidated balance sheet (or in the applicable
notes thereto) of the Company and its subsidiaries other than liabilities or
obligations which arose in the ordinary course of business since such date and
which do not or would not, individually or in the aggregate, have a Material
Adverse Effect.

          SECTION 4.07  Absence of Certain Changes.  Since December 31, 1994,
                        --------------------------                           
except as disclosed in the SEC Reports filed thereafter or as set forth on
Schedule 4.07 hereto, the Company and its subsidiaries have not (i) suffered any
Material Adverse Effect, (ii) changed their accounting methods, principles or
practice or (iii) declared, set aside or authorized any dividend or other
distribution in respect of any capital stock of the Company or any of its
subsidiaries or any redemption, purchase or other acquisition of any of their
respective securities, except for any dividend or distribution paid or payable
by a wholly-owned subsidiary of the Company to the Company or another wholly-
owned subsidiary of the Company.  Since December 31, 1994, except as disclosed
in the SEC Reports filed thereafter or except as set forth on Schedule 4.07
hereto, the Company has conducted its business and operations in the ordinary
course of business consistent with past practice.

          SECTION 4.08  Compliance with Applicable Laws.  Except as disclosed in
                        -------------------------------                         
the SEC Reports, the businesses and operations of the Company and its
subsidiaries are not being conducted in violation of or conflict with any law,
ordinance, order, rule or regulation of any domestic or foreign public body or
authority, except for possible violations which do not, and, insofar as
reasonably can be foreseen, in the future will not, individually or in the
aggregate, have a Material Adverse Effect.

          SECTION 4.09  Employee Benefits and Compensation.  Schedule 4.09
                        ----------------------------------                
hereto sets forth all of the Company's individual employment agreements and any
other plans, programs or arrangements (whether written or oral), covering any
individual, category of individuals or all employees generally, including,
without limitation, any qualified or non-qualified retirement or supplemental
retirement plan, employee benefit plan, incentive, bonus or other compensation
plan or program or any stock option, stock bonus or stock purchase plan or
program (collectively, the "Benefits Arrangements").  The Company has heretofore
made available to Parent or Acquisition true, correct and complete copies of all
Benefit Arrangements.  Except as identified on Schedule 4.09 hereto, no Benefit
Arrangement is a "multi employer plan" (within the meaning of Section 3(37) or
Section 4011(a)(3) of Title IV of the Employee Retirement Income Security Act of
1974, as amended ("ERISA")) or a "multiple employer plan" (within the meaning of
Section 4064 of ERISA or Section 413(c) of the Internal Revenue Code of 1986, as
amended (the "Code")), and neither the Company nor any of its subsidiaries has a
current or potential liability or obligation, whether direct or indirect, with
respect to any multi employer plan or multiple employer plan.  Except as set
forth in the SEC Reports or except as set forth in Schedule 4.09 hereto, (i)
each Benefit Arrangement intended to be qualified under Section 401(a) of the
Code has received a favorable determination letter from the Internal Revenue
Service (the "IRS") that it is so qualified and nothing has occurred since the
date of such letter

                                       12
<PAGE>
 
that could reasonably be expected to affect the qualified status of such plan,
(ii) each Benefit Arrangement has been operated or administrated in all material
respects in accordance with its terms and the requirements of applicable law,
(iii) neither Company nor any of its subsidiaries has incurred any direct or
indirect liability under, arising out of or by operation of ERISA, in connection
with the termination of, or withdrawal from any Benefit Arrangement or other
retirement plan or arrangement, and, to the knowledge of the Company, no fact or
event exists which could reasonably be expected to give rise to any such
liability, (iv) no breach of fiduciary duty, prohibited transaction, or
"reportable event" (within the meaning of Section 4043(b) of ERISA) has occurred
with respect to which the Company, any subsidiary or any Benefit Arrangement may
be liable or otherwise materially damaged, (v) all contributions, premiums, and
other payment obligations with respect to any Benefit Arrangement (A) have been
accrued on the Company's consolidated financial statements in accordance with
GAAP and, to the extent due, have been made on a timely basis and (B) meet the
requirements of deductibility under the Code, and (vi) with respect to each
Benefit Arrangement which provides welfare benefits of the type described in
Section 3(1) of ERISA:  (X) no such Benefit Arrangement provides medical or
death benefits with respect to current or former employees, directors or
consultants of the Company and the subsidiaries beyond their termination of
employment, other than coverage mandated by Sections 601-608 of ERISA and
4980B(f) of the Code, (Y) each such Benefit Arrangement has been administered in
material compliance with Sections 601-608 of ERISA and 4980B(f) of the Code, and
(Z) no such Benefit Arrangement has reserves, assets, surpluses or prepaid
premiums except as disclosed in the financial statements of the Company.  Except
as set forth in the SEC Reports or except as set forth on Schedule 4.09 hereto,
since December 31, 1994, the Company has not increased or established any bonus,
insurance, severance, deferred compensation, pension, retirement, profit
sharing, stock option (including, without limitation, the granting of stock
options, stock appreciation rights, performance awards or restricted stock
awards), stock purchase or other employee benefit plans, or any other increase
in the compensation payable to or to become payable to any officers or key
employees of the Company or any of its subsidiaries other than normal increases
in the ordinary course of business consistent with past practice that do not, in
the aggregate, result in a material increase in benefits or compensation
expenses to the Company or its subsidiaries or an increase in excess of 5% in
the case of any individual.  Notwithstanding the foregoing and except for
compensation based upon the payment of commissions pursuant to commission
schedules previously made available to Parent or Acquisition by the Company,
Schedule 4.09 sets forth a list of all increases to compensation (whether with
respect to salary or benefits) since March 31, 1995 of all employees of the
Company or any of its subsidiaries whose total fixed base

compensation prior to such date exceeded $75,000.  The Company has heretofore
delivered to Parent or Acquisition its reasonable estimate (individually and in
the aggregate) of all amounts (whether currently payable or payable in the
future) payable as a result of a change in control of the Company to which
current or former officers, directors or employees of the Company or its
subsidiaries are entitled or would become entitled after the Offer or the
Merger, under the terms of any Benefits Arrangements other than any amounts
payable from any trust, fund, annuity or other insurance contract, existing as
of the date hereof the proceeds of which are segregated to pay such amounts.

          SECTION 4.10  Taxes.  Each of the Company and the subsidiaries has
                        -----                                               
duly filed, on a timely basis, with the appropriate federal, state, local and
foreign governmental authorities all tax returns and reports required to be
filed by it with respect to any material taxes of any kind and has paid all
taxes shown thereon as owing, and each such return or report is true, complete

                                       13
<PAGE>
 
and accurate in all material respects; provided, however, that as to foreign
taxes of any nature and as to taxes other than income taxes, such representation
is made to the best knowledge of the Company's management after due inquiry.
Except as expressly set forth in the notes accompanying the financial statements
of the Company contained in the 1994 10-K, none of the Company and its
subsidiaries has waived any statute of limitations with respect to any income
tax matter or agreed to any extension of time with respect to any income tax
assessment or deficiency.  None of the Company and its subsidiaries is a party
to any tax allocation or sharing agreement.  None of the Company or its
subsidiaries (i) has been a member of an affiliated group filing a consolidated
federal income tax return (other than a group the common parent of which was the
Company) or (ii) has any liability for the taxes of any person, (other than the
Company and its subsidiaries) under Treas. Reg. (S) 1.1502-6 (or any similar
provision of state, local, or foreign law), as a transferee or successor, by
contract, or otherwise.  The changes, accruals and reserves for taxes reflected
on the June 30, 1995 balance sheet of the Company contained in the Company's
Quarterly Report on Form 10-Q for the fiscal quarter ended on such date are
believed to be adequate for the payment of all material liabilities of, or
payable by, the Company and its subsidiaries for taxes (whether disputed or
not), including interest, penalties and additions to tax, accruing through the
date of such balance sheet.  Except as set forth on Schedule 4.10 hereto, there
are no claims, actions or assessments relating to taxes that could reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect.

          SECTION 4.11  Trademarks, Patents and Copyrights.  The Company and its
                        ----------------------------------                      
subsidiaries own or possess adequate licenses or other valid rights to use all
material patents, patent rights, trademarks, trademark rights, trade names,
trade name rights, copyrights, service marks, trade secrets, applications for
trademarks and for service marks, know-how and other proprietary rights and
information used or held for use in connection with the business of the Company
and its subsidiaries as currently conducted or as contemplated to be conducted,
and except as set forth on Schedule 4.11 hereto, the Company is unaware of any
assertion or claim challenging the validity of any of the foregoing which could
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect.  Except as set forth on Schedule 4.11 hereto, the conduct of the
business of the Company and its subsidiaries as currently conducted does not
conflict in any way with any patent, patent right, license, trademark, trademark
right, trade name, trade name right, service mark or copyright of any third
party that could reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect.  To the best knowledge of the Company's
management after due inquiry, there are no infringements of any proprietary
rights owned by or licensed by or to the Company or any of its subsidiaries
which could reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect.

          SECTION 4.12  Litigation.  Except as and to the extent set forth in
                        ----------                                           
the 1994 10-K or its Quarterly Reports on Form 10-Q filed since that date or
except as set forth on Schedule 4.12 hereto, there is no suit, action, claim or
proceeding pending or, to the knowledge of the Company or its subsidiaries,
threatened against the Company or any of its subsidiaries, which, if adversely
determined, individually or in the aggregate with other such suits, actions,
claims or proceedings, could (i) have a Material Adverse Effect, (ii) materially
and adversely affect the Company's ability to perform its obligations under this
Agreement or (iii) prevent the consummation of any of the transactions
contemplated by this Agreement.

                        -----------------------------                           
threatened or actual claim, action, suit, proceeding or investigation, whether
civil, criminal or administrative, including, without limitation, any such
claim, action, suit, proceeding or investigation in which any of the present or
former officers or directors (the "Managers") of the Company is, or is
threatened to be, made a party by reason of the fact that such person is or was
a director, officer, or employee of the Company, or is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, whether
before or after the Effective Time, the parties hereto agree to cooperate and
use their best efforts to defend against and respond thereto.  From and after
the Effective Time, the Surviving Corporation shall indemnify and hold harmless,
as and to the full extent permitted by the Delaware Law, as it exists or may
hereafter be amended, each such Manager against all expense, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement), reasonably incurred or suffered
by such person in connection with any such claim, action, suit, proceeding or
investigation, and in the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) subject
to the last sentence of this paragraph (a), the Managers may retain counsel
satisfactory to them (provided such counsel is reasonably acceptable to the
Surviving Corporation), and the Surviving Corporation shall pay all reasonable
fees and expenses of no more than one such counsel (and no more than one local
counsel) for the Managers promptly as statements therefor are received, and (ii)
the Surviving Corporation shall use its best efforts to assist in the vigorous
defense of any such matter; provided that, the Surviving Corporation shall not
be liable for any settlement effected without its prior written consent (which
consent shall not be unreasonably withheld); and provided,

                                       22
<PAGE>
 
further, that the Surviving Corporation shall have no obligation hereunder to
any Manager when and if a court of competent jurisdiction shall ultimately
determine, and such determination shall have become final and non-appealable,
that indemnification of such Manager in the manner contemplated hereby is
prohibited by applicable law.  Any Manager wishing to claim indemnification
under this Section 6.06(a), upon learning of any such claim, action, suit,
proceeding or investigation, shall promptly notify the Surviving Corporation
thereof and shall deliver to the Surviving Corporation the undertaking
contemplated by Section 145(e) of the Delaware Law.  The Managers as a group may
retain no more than one law firm (in addition to one local counsel) to represent
them with respect to each such matter unless there is under applicable standards
of professional conduct, a conflict on a significant issue between the positions
of any two or more Managers, in which event such additional counsel as may be
required may be retained.

          (b) The Certificate of Incorporation and By-Laws of the Surviving
Corporation shall contain the provisions with respect to indemnification and
exculpation set forth in the Company's Restated Certificate of Incorporation or
By-Laws on the date of this Agreement, which provisions shall not be amended,
repealed or otherwise modified for a period of five years after the Effective
Time in any manner that would adversely affect the rights thereunder of any
present or former directors, officers, employees, fiduciaries or agents of the
Company (collectively, the "Indemnified Parties") unless such modification is
required by law and the Surviving Corporation shall cause to be maintained (i)
for not less than five years after the Effective Time, the provisions with
respect to indemnification in the certificates or articles of incorporation, by-
laws or similar organizational documents of any of the Company's subsidiaries as
in effect as of the date hereof, and (ii) for not less than the shorter of five
years or the termination date specified therein (if any), the indemnification
agreements entered into between the Company and any of the Indemnified Parties,
in each case, with respect to matters occurring on or prior to the Effective
Time.  For a period of three years after the Effective Time, Surviving
Corporation shall cause to be maintained the current policies of the directors'
and the officers' liability insurance maintained by the Company (provided that
the Surviving Corporation may substitute therefor policies of at least the same
coverage containing terms and conditions which are no less advantageous) with
respect to matters occurring prior to the Effective Time to the extent
available; provided that, in no event shall Surviving Corporation be required to
expend to maintain or procure insurance coverage pursuant to this Section
6.06(b) any amount per annum in excess of 150% of the aggregate premiums paid or
payable in 1995 on an annualized basis for such purpose (which the Company
represents and warrants to be $131,500); provided, however, that in the event
                                         --------  -------                   
the payment of such amount for any year is insufficient to maintain such
insurance, the Surviving Corporation shall purchase as much insurance as may be
purchased for the amount indicated.

          SECTION 6.07  Notification of Certain Matters.  The Company shall give
                        -------------------------------                         
prompt notice to Parent or Acquisition, and Parent or Acquisition shall give
prompt notice to the Company, of (i) any change or event having, or which,
insofar as can reasonably be foreseen, would have a Material Adverse Effect,
(ii) the occurrence, or non-occurrence, of any event the occurrence, or non-
occurrence, of which would be likely to cause any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
at or as of the Effective Time, and (iii) any material failure of the Company,
Parent or Acquisition, as the case may be, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
           --------  -------                                                  
Section 6.07

                                       23

shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

          SECTION 6.08  Prepayment.  At such times following consummation of the
                        ----------                                              
Offer as Acquisition may request, the Company will to the extent of available
working capital or the extent capital is contributed to the Company by Parent or
Acquisition, in the manner and to the extent permitted by the instruments
governing the same, prepay, redeem or retire such indebtedness of the Company
and its subsidiaries as Acquisition may request.

          SECTION 6.09  Acquisition Proposals.  (a)  Neither the Company nor any
                        ---------------------                                   
of its subsidiaries will, directly or indirectly, through any officer, director,
employee, representative or agent of the Company or any of its subsidiaries,
initiate, solicit or encourage (including by way of furnishing non-public
information or assistance) or take any action to knowingly facilitate, any
inquiries or the making of any proposals regarding any merger, sale of
substantial assets, sale of shares of capital stock (including without
limitation by way of a tender offer) or similar transactions involving the
Company or any of its subsidiaries (any of the foregoing inquiries or proposals
being referred to herein as an "Acquisition Proposal").  The Company represents
and warrants that (i) as of the date hereof it has ceased any and all
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing and (ii) prior to the Effective Time, the
Company will not release, terminate or modify the terms of any existing
confidentiality agreement without the prior written consent of Acquisition
except as required by applicable law or in good faith (upon advice of counsel)
that such action is required in order that the Board discharge its fiduciary
duties.  Nothing contained in this Section 6.09 shall prevent the Board from
considering, negotiating, approving and recommending to the stockholders of the
Company a bona fide Acquisition Proposal not solicited in violation of this
Agreement, provided the Board determines in good faith (upon advice of counsel)
that it is required to do so in order to discharge its fiduciary duties.

          (b) The Company shall immediately notify Acquisition after receipt of
any Acquisition Proposal, or any modification of or amendment to any Acquisition
Proposal, or any request for non-public information relating to the Company or
any of its subsidiaries in connection with an Acquisition Proposal or for access
to the properties, books or records of the Company or any subsidiary by any
person or entity that informs the Board or such subsidiary that it is
considering making, or has made, an Acquisition Proposal.  Such notice to
Acquisition shall be made orally (within one business day) and in writing (as
soon thereafter as practicable), and shall indicate whether the Company is
providing or intends to provide the person making the Acquisition Proposal with
access to information concerning the Company.

          (c) If the Board receives a request for non-public information by a
person who makes a bona fide Acquisition Proposal, and the Board determines in
good faith (upon the advice of counsel) that it is required to cause the Company
to act as provided in this Section 6.09 in order to discharge properly its
fiduciary duties, then, provided the person making the Acquisition Proposal has
executed a confidentiality agreement substantially equivalent to the one then in
effect between the Company and Charles B. McNamee, the Company may provide such
person with access to information regarding the Company.

          SECTION 6.10  HSR Act Filing.  To the extent required by applicable
                        --------------

law, the Surviving Corporation and its subsidiaries to provide benefit plans to

less favorable than those in effect as of the date on which the Offer is
consummated.

          take action under this Agreement) determines in good faith (upon
          advice of counsel) that such recommendation is inconsistent with its
          performance of its fiduciary duties under applicable law as determined
          by the members thereof by a majority vote; and

               (iii)  use its reasonable best efforts (A) to obtain and furnish

          to be prepared by the Company and filed as soon as reasonably
          practicable following consummation of the Offer with the SEC with

     Parent and Acquisition agree that they will cause all Shares then owned by
them and their subsidiaries to be voted in favor of approval and adoption of
this Agreement and the transactions contemplated hereby.

     (b) Notwithstanding the foregoing, in the event that Parent shall acquire
at least ninety percent (90%) of the outstanding Shares, the parties hereto
agree, at the request of Parent, to take all necessary and appropriate action to
cause the Merger to become effective (or, as contemplated by Section 2.01
hereof, to cause a merger of Acquisition (or any other direct or indirect
subsidiary of Parent) into the Company to become effective), as soon as
reasonably practicable after the expiration of the Offer, without a meeting of
the stockholders of the Company, in accordance with Section 253 of the Delaware
Law.

preparation, execution and performance of this Agreement, the Financing and any
definitive financing agreements relating thereto up to a maximum of $750,000
(all of the foregoing being referred to collectively as the "Expenses").

     (c)(i)  If Parent does not accept for payment Shares pursuant to the Offer
on or prior to the date which is sixty (60) days following commencement of the
Offer, because of the failure of Parent to satisfy clause (iii) of Annex A
hereto, then Parent, within two days of any termination pursuant to Section
8.01(d) hereof, shall pay to the Company an amount equal to $750,000;

     (ii)  If this Agreement is terminated based upon a breach of any material
representation, warranty, covenant or agreement on the part of Acquisition or
Parent set forth in this Agreement (other than any representation, warranty or
covenant relating to the Financing which shall be governed solely by subsection
(c)(i) of this Section), then Parent, within two days of any termination
pursuant to Section 8.01(d) hereof, shall pay to the Company an amount equal to
$1,500,000;

     (iii)  SPII shall enter into an agreement acceptable to SPII and the

     (d)  Except as provided in Section 8.03(a), (b) and (c) hereof, all costs
and expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses

exhibits, amendments or supplements thereto).

     SECTION 8.04  Amendment.  Subject to Section 1.03(c) hereof, this Agreement

may be amended by action taken by the Company, Parent and Acquisition at any
time before or after adoption of the Merger by the stockholders of the Company
(if required by applicable law); provided that, after any such approval, no
amendment shall be made which decreases the Per Share Amount or which materially
adversely affects the rights of the Company's stockholders hereunder without the
approval of such stockholders; and, provided, further, that after consummation
of the Offer any amendment referred to in the foregoing provision shall require
approval of a majority of the Shares not beneficially owned by Parent,
Acquisition or any of their Affiliates.  This Agreement may not be amended
except by an instrument in writing signed on behalf of the parties.

     SECTION 8.05  Extension; Waiver.  Subject to Section 1.03(c) hereof, at any
                   -----------------

the performance of any of the obligations or other acts of the other party, (ii)
waive any inaccuracies in the representations and warranties of the other party
contained herein or in any document, certificate or writing delivered pursuant
hereto or (iii) waive compliance by the other party with any of the agreements
or conditions contained herein.  Any agreement on the part of either party
hereto to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.  The failure of either
party hereto to assert any of its rights hereunder shall not constitute a waiver
of such rights.

     action or proceeding to be determined in a manner satisfactory to Parent;
     or

          (b) any material adverse change or development shall have occurred, or
     Parent shall have become aware of any fact that would reasonably be
     expected to result in any change or development, in the business, assets,
     liabilities, capitalization, earnings, operations, financial condition or
     results of operations of the Company and its subsidiaries, taken as a
     whole, that in the reasonable judgment of Parent, has or would reasonably
     be expected to have a Material Adverse Effect; or

          (c) there shall have occurred (i) any general suspension of trading

     described in clauses (i) through (iv) inclusive, existing at the date of
     the commencement of the Offer, a material acceleration or worsening
     thereof; or

          (d) the Company shall have breached or failed to perform any of its
     covenants or agreements which breach is material to the obligations of the
     Company under the Agreement or any of the representations and warranties of
     the Company set forth in the Agreement shall not be true in any material
     respect, in each case, when made or at any time prior to consummation of
     the Offer; or

          (e) the Agreement or the Stockholders Option Agreement shall have been
     terminated; or

          (f) the Board shall have publicly (including by amendment of the
     Schedule 14D-9) withdrawn or modified in a manner adverse to Parent:  (i)
     its approval or recommendation of the Offer, the Merger or the Agreement,

     contained in Section 203 of the Delaware Law not to apply to the
     transactions contemplated hereby, the Offer or the Stockholders Option
     Agreement or shall have resolved to do so; or

          (g) any party to the Stockholders Option Agreement other than Parent
     shall have breached or failed to perform in any material respect any of its
     agreements under the Stockholders Option Agreement or any of the
     representations and warranties of any such party set forth in the

     principle with respect to any Acquisition Proposal; or

          (i) Parent, Acquisition and the Company shall have agreed that Parent
     shall terminate the Offer or postpone the payment for Shares thereunder;

which, in the reasonable judgment of Parent in any such case, and regardless of
the circumstances giving rise to any such condition makes it inadvisable to
proceed with such acceptance for payment or payments.

     The foregoing conditions are for the benefit of Parent and Acquisition and
may be asserted by Parent and/or Acquisition regardless of the circumstances
giving rise to any such condition or, except as otherwise provided herein, may
be waived by Parent in whole or in part at any time and from time to time in its
sole discretion.  The failure by Parent at any time to assert any of the
foregoing conditions shall not be deemed a waiver of any such condition and each
such condition shall be deemed an ongoing condition which may be asserted at any
time and from time to time.

purpose of making the Tender Offer and acquiring and holding the shares of TIE

obligations under the Merger Agreement, and the commencement and making of the

           have no reasonable likelihood of having a Material Adverse Effect; or

                (iv)       result in the creation or imposition of any Lien upon
           any of the property of Borrower or Merger Co., other than pursuant to

     4.3   Enforceable Obligations.  This Agreement and the other Loan Documents
           -----------------------

when delivered hereunder will be, legal, valid and binding obligations of
Borrower, enforceable against Borrower in accordance with their respective
terms, except as such enforcement may be limited by applicable bankruptcy,

           -----                                                               
returns which are required to have been filed in any jurisdiction and have paid
all taxes shown to be due thereon or otherwise assessed, to the extent the same
have become due and payable and before they have become delinquent, except for
any taxes and assessments the amount, applicability or validity of which is
currently being contested in good faith by appropriate proceedings and with
respect to which Borrower has set aside on its books reserves (adequate in
accordance with, and segregated to the extent required by, GAAP) and the non-
filing or non-payment of which has no reasonable likelihood of having a Material
Adverse Effect.

     4.5   Financial Matters.
           ----------------- 

           (a)  The October 18, 1995 pro forma balance sheet of Borrower, a copy
which has been delivered by Borrower prior to the execution of this Agreement to
Lender, is complete and correct in all material respects and fairly represents
on a pro forma basis the financial condition of Borrower, TIE, and their
Subsidiaries, and reflects on a pro forma basis those liabilities reflected in
the notes thereto and resulting from the transactions contemplated by the Tender
Offer, including the financing therefor and the payment of all fees and expenses
in connection therewith; and the assumptions expressed therein were reasonably
based on the information available to Borrower at the time so furnished.  To
Borrower's knowledge, the unaudited financial statements of TIE contained in
TIE's Form 10-Q for the fiscal quarter ended September 30, 1995, a copy of which

Lender, are complete and correct and fairly represent in all material respects
the financial condition of TIE and its Subsidiaries.

           (b)  Since the date of the financial statements referred to in clause
(a) above, there has been no Material Adverse Effect and no development which
has a reasonable likelihood of having a Material Adverse Effect.

           (c)  To Borrower's knowledge, there is no obligation, contingent
liability or liability for taxes, long-term leases or unusual forward or long-
term commitments, which is not reflected in the financial statements of TIE
delivered pursuant to clause (a) above, or in the notes thereto, which are
required by GAAP to be disclosed and which would have a Material Adverse Effect.

           (d)  Each of Borrower and Merger Co. is Solvent.

     4.6   Litigation.  There are no pending or, to the knowledge of Borrower,
           ----------                                                         
threatened,

                                     -16-
<PAGE>
 
actions or proceedings affecting Borrower, TIE, or any of their Subsidiaries,
before any court or other Governmental Authority or any arbitrator that has a
reasonable likelihood of having a Material Adverse Effect.  To the best of
Borrower's knowledge, all pending or threatened actions or proceedings affecting
Borrower, TIE, or any of their Subsidiaries, as of the date hereof are described

or the consummation of the Merger or the performance by Borrower or Merger Co.
of any of the Loan Documents to which it is a party is restrained or enjoined
(either temporarily, preliminarily or permanently) and no conditions have been
imposed upon any of the foregoing transactions as a result of any such action or
proceeding, compliance with which would have a Material Adverse Effect.

     4.7   Subsidiaries.  Borrower has no Subsidiaries other than Merger Co. and
           ------------                                                         
on and after the Tender Funding Date, TIE and its Subsidiaries.

     4.8   Liens.  There are no Liens of any nature whatsoever on any properties
           -----                                                                
of Borrower, TIE, or any of their Subsidiaries, other than Permitted Liens.

     4.9   No Burdensome Restrictions; No Defaults.
           --------------------------------------- 

           (a)  Neither Borrower, nor any Subsidiary of Borrower, is a party to
any Contractual Obligation the performance of which has a reasonable likelihood
of having a Material Adverse Effect or the performance of which by any thereof
will result in the creation of a Lien on the property or assets of any thereof
other than a Permitted Lien.

           (b)  As of the Tender Funding Date, no provision or provisions of any
applicable Requirement of Law has a reasonable likelihood of having a Material
Adverse Effect.

           (c)  Neither Borrower, nor any Subsidiary of Borrower, is in default
under or with respect to any Contractual Obligation (or any other agreement or
instrument to which Borrower or such Subsidiary is a party) which is material to
the financial condition, operations, business, properties, or prospects of
Borrower or any such Subsidiary, or which default, individually or in the
aggregate, has a reasonable likelihood of having a Material Adverse Effect.

           (d)  No Default or Event of Default has occurred and is continuing.

     4.10  Tender Offer Documents and Related Documents.  The Offer to Purchase
           --------------------------------------------               
has not been amended or modified in any respect, and no provision therein has
been waived, except, in each case, in accordance with Section 3.2(a)(ii).
                                                      ------------------

     4.11  Investment Company Act; Public Utility Holding Company Act. Neither

Borrower nor any Subsidiary of Borrower is an "investment company" or an
"affiliated person" of, or "promoter" or "principal underwriter for" for, an
"investment company," as such terms are defined in the Investment Company Act of
1940, as amended, or a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company," within the meaning

making of the Loan by Lender, the application of the proceeds and repayment
thereof by Lender, the application of the proceeds and repayment thereof by

as amended, or any rule, regulation or order issued by the Securities and

                                                    --------  -------   
request by Parent for the making of a Facility B Loan shall be deemed to be a

entitled to treat the making of the Facility B Loans as a simultaneous repayment
by Parent of the Affiliate Loan and a repayment by TI of the Facility A Loans;
(ii) be entitled to apply the proceeds of the Facility B Loans to the
outstanding principal balance of the Facility A Loans and to the accrued and
unpaid interest thereon; and (iii) be obligated to remit to Parent the proceeds
of the Facility B Loans only to the extent such proceeds exceed the outstanding
principal balance of the Facility A Loan owed to such Lender and to the accrued
and unpaid interest thereon; provided, further, neither Lender shall have any

Notes").

          2.2       BORROWING PROCEDURES.

          (a)       Borrower shall give each Lender written notice of each
request for a Loan hereunder in accordance with subsection (b) below. Not later
than 2:00 p.m. (prevailing Eastern time), on the date specified for each
borrowing hereunder, each Lender shall make available to the relevant Borrower,
at the principal office of such Lender, the amount of the Loan to be made and
disbursed by such Lender, in immediately available funds.

          (b)       All notices given by Borrowers, or either of them, to the
Lenders of borrowings of Loans hereunder shall either be oral, with prompt
written confirmation (which may be by telecopy) or in writing; shall be
irrevocable; shall be effective only if received by Lenders prior to 10:00 a.m.
(prevailing Eastern time) on a Business Day which is at least five (5) days
prior to the Tender Date, in the case of the Facility A Loan, or five (5) days
prior to the Merger Date, in the case of the Facility B Loan. Each such notice
shall specify: (1) the amount of such borrowing; and (2) the date such Loan is
to be made, (which shall be a Business Day). Each request for a borrowing
pursuant to this Agreement or the other Loan Documents shall constitute (x) an
automatic warranty and representation by Borrowers to Lenders that there does
not then exist a Default or Event of Default or any event or condition which,
with the making of such Loan, would constitute a Default or Event of Default and
(y) an affirmation that as of the date of such request all of the
representations and warranties of Obligors contained in

                                       9
<PAGE>
 
this Agreement and the other Loan Documents are true and correct in all material
respects, both before and after giving effect to the making of such Loan.

          2.3       PRINCIPAL PAYMENTS; PREPAYMENTS.

          (a)       TI shall pay all principal, accrued and unpaid interest, and
other charges and expenses in connection with the Facility A Loan in full on the
earlier to occur of the Merger Date and December 29, 1995. Parent shall pay all
principal, accrued and unpaid interest, and other charges and expenses in
connection with the Facility B Loans in full on the Maturity Date.

          (b)       Each payment by the Borrowers to Lenders pursuant to this
Agreement or the Notes shall be made prior to 1:00 p.m. (prevailing Eastern
time) on the date due and shall be made without set-off or counterclaim by wire
transfer to the account of each such Lender specified for such Lender on its
signature page hereto or at such other place or places as such Lender may
designate from time to time in writing to Borrowers.  Each such payment shall be
in lawful currency of the United States of America and in immediately available
funds.

          (c)       Each payment made by Borrowers hereunder shall either (i) be
exempt from, and be made without reduction by reason of, any Tax or (ii) to the
extent that any such payment shall be subject to any Tax, be accompanied by an
additional payment by Borrowers of such amount as may be necessary so that the
net amount received by the Lenders (after deducting all applicable Taxes) is the
same as Lenders would have received had such payment not been subject to such
Tax.  Upon any payment of Tax by Borrowers, Borrowers shall promptly (and in any
event within 30 days) furnish to the Lenders such tax receipts, certificates and
other evidence of such payment as Borrowers may have or the Lenders may
reasonably request.

          (d)       If the due date of any payment hereunder or under any of the
Notes would otherwise fall on a day which is not a Business Day, then such
payment shall be due on the next succeeding Business Day and interest shall be
payable on the principal amount of such payment for the period of such
extension.

          (e)       The Loans may be prepaid, in whole or in part, without
premium or penalty, in integral multiples of $100,000, at any time upon written
notice to the Lenders on the date and in the amount specified in such notice, by
paying to the Lenders the amount of such prepayment and all accrued and unpaid
interest thereon.

          2.4       USE OF PROCEEDS.  The proceeds of the Loans shall be used as
follows:

          (a) TI shall use the proceeds of the Facility A Loans to fund the
Affiliate Loan to Parent and Parent shall use the proceeds of the Affiliate Loan
to provide a portion of the cash payments required to complete the Tender Offer;
and

                                      10
<PAGE>
 
          (b) Parent shall use the proceeds of the Facility B Loans, (i) to the
extent of the outstanding principal and accrued and unpaid interest on the
Facility A Loan, to repay the Affiliate Loan and TI shall use the proceeds of
such payment to pay in full the outstanding principal amount of the Facility A
Loan and all accrued interest thereon and (ii) to the extent of the balance, to
provide a portion of the consideration payable to the shareholders (other than
Parent) of the Company pursuant to the Merger.

          No portion of the proceeds of any Loan may be used by the Borrowers,
or either of them, in any manner which would cause such Loan or the application
of the proceeds thereof to violate any of Regulations G, T, U or X of the Board
of Governors of the Federal Reserve System.

          2.5       SEVERAL OBLIGATIONS OF BANKS; REMEDIES INDEPENDENT.  The
failure of any Lender to make any Loan required to be made by it on the date
specified therefor shall not relieve any other Lender of its obligation to make
its Loan on such date, but neither the other Lender nor the Collateral Agent
shall be responsible for the failure of a Lender to make a Loan to be made by
such other Lender (the Lender able and willing to fund being hereinafter
referred to as the "Non-Defaulting Lender" and the party unable and unwilling to
fund being hereinafter referred to as the "Defaulting Lender"); provided,
                                                                -------- 
however, that if any Lender is a Defaulting Lender, then:
- -------                                                  

          (a) with respect to the Defaulting Lender (i) the Parent shall be
     entitled to a prompt refund of the Cash Commitment Fee paid to the
     Defaulting Lender; (ii) Parent shall be under no obligation to issue the
     Warrants to the Defaulting Lender and any Warrants previously issued to the
     Defaulting Lender shall be null and void; and (iii) Parent or TI, as the
     case may be, shall have all of its remedies in law or equity with respect
     to such failure to fund; and

          (b)       unless the Non-Defaulting Lender shall actually fund the
     amount requested by Borrower in accordance with the terms of Section
     hereof; (i) the Non-Defaulting Lender shall upon notice from Parent
     promptly refund its respective portion of the Cash Commitment Fee to
     Parent; and (ii) Parent shall be under no obligation to issue the Warrants
     to the Non-Defaulting Lender and the Non-Defaulting Lender shall return to
     Parent any Warrants previously issued to the Non-Defaulting Lender;

          (c)       if the Non-Defaulting Lender makes the entire amount of the
     Loans properly requested by Borrower in accordance with the terms of
     Section hereof: the Non-Defaulting Lender shall be entitled (i) to act as
     Collateral Agent and to receive all payments to be made under this
     Agreement, the Notes, and the other Loan Documents; (ii) to receive all
     warrants to be issued pursuant to this Agreement and the other Loan
     Documents; and (iii) to receive from the Borrower the Defaulting Lender's
     share of the Cash Commitment Fee. TI and Parent agree that in such event
     the Non-

                                      11
<PAGE>
 
     Defaulting Lender shall be entitled to deduct the amount to which it is
     entitled pursuant to clause (iii) above from the proceeds of the Loan made
     by it.

The amounts payable by Borrowers at any time hereunder and under the Notes to
each Lender shall be a separate and independent debt and each Lender shall be
entitled to protect and enforce its rights arising out of this Agreement and the
Notes, and it shall not be necessary for any other Lender or the Collateral
Agent to consent to, or be joined as an additional party in, any proceeding for
such purposes.

          2.6       PRO RATA TREATMENT.  Except to the extent otherwise provided
herein: (a) each borrowing from the Lenders under Sections  hereof shall be made
from the Lenders and each payment of the Cash Commitment Fee under Section
hereof shall be made for the account of the Lenders, pro rata according to their
Pro Rata Share; and (b) each payment or prepayment of principal of Loans shall
be made for the account of relevant Lenders pro rata in accordance with the
respective unpaid principal amounts of the relevant Loans held by such Lenders.


                             3.  FEES AND INTEREST

          3.1       INTEREST.

          (a)       Subject to modification pursuant to Section hereof, the

interest from the date thereof until paid in full at the following rates:

                    (i)       the outstanding principal amount of the Loan shall
          bear interest at the rate of ten percent (10%) per annum, calculated
          daily on the basis of a 360-day year and actual days elapsed; or

                    (ii)      the amount of any payment of principal and, to the
          extent permitted by Applicable Law, interest or other amount payable
          hereunder which is not paid when due, shall, unless otherwise elected
          by the Lenders, bear interest at the Default Rate.

          (b)       Accrued interest shall be payable (i) in the case of the
Facility A Loans, on the earlier to occur of the Merger Date and December 29,
1995; and (ii) in the case of the Facility B Loans, on the first day of each
month for the previous month, commencing with the first such date after the
Merger Date.

          3.2       CASH COMMITMENT FEE.  Parent has heretofore paid to the
Lenders a cash commitment fee (the "Cash Commitment Fee") in an amount equal to
$200,000.00. Except

                                      12
<PAGE>
 
as provided in Section  hereof, such fee was fully earned and non-refundable on
payment thereof, and shall not be subject to proration or rebate for any reason.

          3.3       ISSUANCE OF WARRANTS AS PORTION OF COMMITMENT FEE, AS
CLOSING FEE, AND BASED ON TIME OF REPAYMENT. Parent has also agreed to issue
certain warrants to the Lenders (the "Warrants") as described in more detail in
the Warrant Agreement, with such Warrants to be issued as a portion of the
commitment fee for the Term Loan, as a closing fee upon execution of this
Agreement, and based on the time of repayment by Borrowers of the Term Loan.

          3.4       INCREASED COSTS AND REDUCED RETURN.

          (a)       If any Lender shall have determined that the applicability
of any law, rule, regulation or guideline adopted pursuant to or arising out of
the July 1988 report of the Basle Committee on Banking Regulations and
Supervisory Practices entitled "International Convergence of Capital Measurement
and Capital Standards," or the adoption after the date hereof of any other law,
rule, regulation or guideline regarding capital adequacy, or any change in any
of the foregoing or in the enforcement or interpretation or administration of
any of the foregoing by any court or any central bank or other Governmental
Authority, charged with the enforcement or interpretation or administration
thereof, or compliance by such Lender (or any lending office of such Lender) or
one of such Lender's parent company with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on such Lender's capital or on the capital of such Lender's
parent company, if any, as a consequence of its making or maintaining any Loan
or its incurring any obligations under this Agreement to a level below that
which such Lender or such Lender's parent company could have achieved but for
such applicability, adoption, change or compliance (taking into consideration
such Lender's policies and the policies of such Lender's parent company with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then, upon demand by such Lender, the Borrowers, jointly and severally, hereby
- ----             
agree to pay to such Lender from time to time such additional amount or amounts
as will compensate such Lender or such Lender's parent company for any such
reduction suffered.

          3.5       INDEMNITY.   Each Borrower hereby indemnifies and agrees to
hold harmless each of the Lenders from and against any and all losses or
expenses which such Lender may sustain or incur as a consequence of failure by
such Borrower to consummate any notice of prepayment or borrowing made by such
Borrower.  Borrowers' obligations under this Section shall survive the
termination of this Agreement and the repayment of the Obligations.

          3.6       NOTICE OF AMOUNTS PAYABLE TO LENDERS.  If a Lender shall
seek payment of any amounts from Borrowers pursuant to Sections , , or hereof,
it shall promptly notify Borrowers of the amount payable by Borrowers to the
Lender thereunder. A certificate of the Lender seeking payment pursuant to
Sections , or hereof, setting

                                      13
<PAGE>
 
forth in reasonable detail the factual basis for and the computation of the
amounts specified, shall be conclusive and binding on all parties for all
purposes, absent manifest error, as to the amounts owed.  Borrowers' obligations
under this Section shall survive the termination of this Agreement and the
repayment of the Obligations.

          3.7       INTEREST SAVINGS CLAUSE.   Nothing contained in this
Agreement or in the Notes or any other Loan Documents shall be construed to
permit the Lenders to receive at any time interest, fees or other charges in
excess of the amounts which the Lenders are legally entitled to charge and
receive under any law to which such interest, fees or charges are subject. In no
contingency or event whatsoever shall the compensation payable to the Lenders by
Borrowers, or either of them, howsoever characterized or computed, hereunder or
under any of the Notes or under any other agreement or instrument evidencing or
relating to the Obligations, exceed the highest rate permissible under any law
to which such compensation is subject. There is no intention that either Lender
shall contract for, charge or receive compensation in excess of the highest
lawful rate, and, in the event it should be determined that any excess has been
charged or received, then, ipso facto, such rate shall be reduced to the highest
                           ---- -----

the Lenders shall apply such excess against the Loans then outstanding and then
to any other Obligations and, to the extent of any amounts remaining thereafter,
refund such excess to Borrowers.

                       4. REPRESENTATIONS AND WARRANTIES

     In order to induce the Lenders to enter into this Agreement and to make
Loans hereunder, Borrowers, jointly and severally, hereby make the following
representations and warranties to the Lenders which shall be true and correct in
all material respects on the date hereof and shall continue to be true and
correct in all material respects at the time of the making of any Loan and until
the Loans have been repaid in full:

          4.1       CORPORATE EXISTENCE AND QUALIFICATION.  TI, Parent, and each
Obligor identified as a corporation in any of the Loan Documents  (collectively,
"Corporate Obligors," and, individually, a "Corporate Obligor") is organized,
validly existing and in good standing under the laws of the state of its
incorporation.  Each Corporate Obligor is duly qualified as a foreign
corporation in good standing in each state wherein the conduct of its business
or the ownership of its property requires such qualification except where the
failure to so qualify would not have a Material Adverse Effect.

          4.2       PARTNERSHIP MATTERS.  Each of Pledgor and any other Obligor
identified as a partnership in any of the Loan Documents (collectively,
"Partnership Obligors," and individually a "Partnership Obligor") is a
partnership duly organized, validly existing and in good standing under the laws
of that Obligor's state of organization, and no events have occurred which have
or would result in dissolution or winding up of the affairs of any of the
Partnership Obligors.  To the extent required by the laws of any state where a
Partnership Obligor conducts its business or owns property, the Partnership
Obligors are duly qualified to

                                      14
<PAGE>
 
do business in such states as partnerships organized under the laws of a
different jurisdiction except where the failure to so qualify would not have a
Material Adverse Effect.

          4.3       AUTHORITY; VALID AND BINDING EFFECT.  Each Corporate Obligor
and each Partnership Obligor has the power and authority to execute, deliver and
perform under this Agreement and the other Loan Documents to which it is a
party, and to borrow hereunder, and has taken all necessary and appropriate
partnership or corporate action to authorize the execution, delivery and
performance of this Agreement and such other Loan Documents.  This Agreement and
the other Loan Documents to which each such Obligor is a party constitute the
valid and legally binding obligations of such Obligor, enforceable against such
Obligor in accordance with their respective terms; except that enforceability
may be limited by bankruptcy, insolvency and other laws affecting creditor's
rights generally and except that the availability of certain remedies may be
limited by general principles of equity.

          4.4       NO CONFLICT.  The execution, delivery and performance by
each Obligor of this Agreement and the other Loan Documents (a) are not in
contravention of any provisions of Applicable Law applicable to such Obligor;
(b) will not violate or result in a default under any material agreement or
indenture to which such Obligor is a party or by which such Obligor is bound;
(c) do not contravene the Certificate or Articles of Incorporation or By-laws of
any Corporate Obligor nor the partnership agreement of any Partnership Obligor;
and (d) will not result in or require the creation or imposition of any Lien on
any of the property or assets of such Obligor other than Liens on the Pledged
Shares in favor of the Lenders created by the Loan Documents.

          4.5       GOVERNMENTAL ACTION.  The execution, delivery and
performance of this Agreement and the other Loan Documents by the Obligors do
not require any registration with, consent or approval of, or any notice to, or
other action to, with or by any Governmental Authority except filings, consent
or notices which have been obtained and a copy thereof furnished to the Lenders.

          4.6       NO LITIGATION.  Except as set forth on Schedule 4.6 hereto,
                                                           ------------
there are no proceedings pending or threatened against TI, Parent, or Pledgor
before or by any court or administrative agency.

          4.7       SOLVENCY.  After giving effect to the execution and delivery
of this Agreement, the Loan Documents, the consummation of the transactions
contemplated hereby and thereby and the making of each Loan hereunder, each
Obligor is Solvent.

          4.8       TAXES.  Each Obligor has filed all federal, state, local and
foreign tax returns, reports and estimates which are required to be filed by it
and all taxes (including penalties and interest, if any) shown on such returns,
reports and estimates as being due and payable or which are otherwise due and
payable have been fully paid.  Such tax returns properly and correctly reflect
the income and taxes of such Obligor for the periods covered thereby.  The

                                      15

as of October 18, 1995, a true and correct copy of which has been delivered to
Lenders, giving effect to the consummation of the Tender Offer, the Merger and
the other transactions contemplated thereby and hereby, contains no material
misstatement or omission and fairly presents the financial position of Parent as
of the date thereof, giving effect to the consummation of the Tender Offer, the
Merger and the other transactions contemplated thereby and hereby, based on the
assumptions set forth therein and herein.

          4.10      TITLE TO ASSETS.  Each Obligor that has executed a Stock
Pledge Agreement has good and marketable title to and ownership of the portion
of the Pledged Shares identified as that Obligor's property on Schedule I to the
Stock Pledge Agreement, free and clear of any and all Liens whatsoever, and none
of the Pledged Shares are subject to any "lock-up" or similar arrangement which
would prevent the pledge to Lenders of such stock or, with the exception of the
DLJ Letter Agreement, would prevent, delay, or otherwise affect the resale of
such stock by the Collateral Agent or the Lenders. Each Obligor that provides
any Collateral other than Pledged Shares after execution of this Agreement has
good and marketable title to and ownership of that Collateral, free and clear of
any and all Liens whatsoever, and none of that Collateral is subject to any
arrangements which would prevent its pledge to, or resale by, Lenders.

          4.11      VIOLATIONS OF LAW.  No Obligor is in violation of any
applicable statute, rule, regulation or ordinance of any Governmental Authority,
the violation of which could reasonably be expected to have a Material Adverse
Effect.

          4.12      MARGIN STOCK.  No Obligor is engaged principally, or as one
of its important activities, in the business of extending credit for buying or
carrying Margin Stock, and the consummation of the transactions contemplated by
this Agreement, including, but not limited to, the Tender Offer, the Merger, the
making of the Loans and the use of the proceeds thereof, shall result in the
violation of Regulations G, T, U or X of the Board of Governors of the Federal
Reserve System.

agreement relating to Indebtedness to which such Obligor is a party or by which
such Obligor is bound or (b) any other instrument, document or agreement to
which such Obligor is a party or by which such Obligor or any of such Obligor's
properties are bound, the default of which would have a Material Adverse Effect.

conduct any litigation or collection proceedings hereunder; and (d) shall not be
responsible for any action taken or omitted to be taken by it hereunder or under
any other agreement, document or instrument referred to or provided for herein
or in connection herewith, except for its own gross negligence or willful
misconduct. The Collateral Agent may employ agents and attorneys-in-fact and
shall not be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it in good faith. The Collateral Agent may deem
and treat the payee of any Note as the holder thereof for all purposes hereof
unless and until a written notice of the assignment or transfer complying with
the terms and conditions of Section hereof.

          10.2   RELIANCE BY COLLATERAL AGENT.  The Collateral Agent shall be
entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telex, facsimile, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel, independent accountants and other experts selected by the
Collateral Agent.

                                      31
<PAGE>
 
As to any matters not expressly provided for by this Agreement, the Collateral
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder in accordance with instructions signed by the Lenders, and
such instructions and any action taken or failure to act pursuant thereto shall
be binding on the Lenders; provided, however, the Collateral Agent shall not be
                           --------  -------                                   
required to take any action which (a) the Collateral Agent reasonably believes
will expose it to personal liability unless the Collateral Agent receives an
indemnification satisfactory to it from the Lenders with respect to such action
or (b) is contrary to this Agreement, the Notes, the other Loan Documents or
Applicable Law.

          10.3   DEFAULTS.  The Collateral Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default or Event of Default unless
the Collateral Agent has received notice from a Lender or the Borrower
specifying such Default or Event of Default and stating that such notice is a
"Notice of Default."  In the event that the Collateral Agent receives such a
notice of the occurrence of a Default or Event of Default, the Collateral Agent
shall (subject to Section  hereof) take such action with respect to such Default
or Event of Default as shall be directed by Lenders, provided that, unless and
until the Collateral Agent shall have received such directions, the Collateral
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interest of the Lenders.

          10.4   RIGHTS AS A LENDER.  With respect to its obligations to make
loans hereunder and the Loans made by it, Creditanstalt (and any successor
acting as Collateral Agent) in its capacity as a Lender hereunder shall have the
same rights and powers hereunder as any other Lender and may exercise the same
as though it were not acting as the Collateral Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include Creditanstalt
in its individual capacity.  Creditanstalt (and any successor acting as
Collateral Agent) and its Affiliates may (without having to account therefor to
any Lender) accept deposits from, lend money to and generally engage in any kind
of banking, trust or other business with Borrower (and any of its Affiliates) as
if it were not acting as the Collateral Agent, and Creditanstalt and its
Affiliates may accept fees and other consideration from Borrower for services in
connection with this Agreement or otherwise without having to account for the
same to the any Lender.

          10.5   INDEMNIFICATION.  The Lenders agree to indemnify the Collateral
Agent (to the extent not reimbursed under Sections or hereof, but without
limiting the respective obligations of Borrowers under said Sections and ), for
their Pro Rata Share of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Collateral Agent in any way relating to or arising out of this
Agreement or any other instruments, documents or agreements contemplated by or
referred to herein or the transactions contemplated hereby (including, without
limitation, the costs and expenses which either Borrower is obligated to pay
under Section hereof but excluding, unless an Event of Default has occurred and
is continuing, normal administrative costs and

                                      32
<PAGE>
 
expenses incident to the performance of its agency duties hereunder) or the
enforcement of any of the terms hereof or of any such other instruments,
documents or agreements, provided that no Lender shall be liable for any of the
foregoing to the extent they arise from the gross negligence or willful
misconduct of the party to be indemnified.  The obligations of the Lenders under
this Section  shall survive the termination of this Agreement.

          10.6   NON-RELIANCE ON COLLATERAL AGENT AND OTHER LENDERS.  Each
Lender agrees that it has, independently and without reliance on the Collateral
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Borrowers, MIDCOM and
the other Obligors and its own decision to enter into this Agreement and that it
will, independently and without reliance upon the Collateral Agent or any other
Lender, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own analysis and decisions in taking or not
taking action under this Agreement.  The Collateral Agent shall not be required
to keep itself informed as to the performance or observance by the Borrowers,
MIDCOM or the other Obligors of this Agreement or any other instrument, document
or agreement referred to or provided for herein or to inspect the properties or
books of the Borrowers, MIDCOM or the other Obligors.  Except for notice,
reports and other documents and information expressly required to be furnished
to the Lenders by the Collateral Agent hereunder or under the Loan Documents,
the Collateral Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Obligors (or any of their Affiliates) which may
come into the possession of the Collateral Agent or any of its Affiliates.

          10.7   FAILURE TO ACT.  Except for action expressly required of the
Collateral Agent hereunder and under the Loan Documents, the Collateral Agent
shall in all cases be fully justified in failing or refusing to act hereunder
unless it shall receive further assurances to its satisfaction from the Lenders
of their indemnification obligations under Section  hereof against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

          10.8   RESIGNATION OF COLLATERAL AGENT.  Subject to the appointment
and acceptance of a successor Collateral Agent as provided below, the Collateral
Agent may resign at any time by giving notice thereof to the Lenders and the
Borrowers. Upon any such resignation, the Lenders shall have the right to
appoint a successor Collateral Agent. If no successor Collateral Agent shall
have been so appointed by the Lenders and shall have accepted such appointment
with thirty (30) days after the retiring Collateral Agent's giving of notice of
resignation, the retiring Collateral Agent may, on behalf of the Lenders,
appoint a successor Collateral Agent, which shall be a bank which has a combined
capital and surplus of at least Three Hundred Million Dollars ($300,000,000).
Upon the acceptance of any appointment as Collateral Agent, such successor
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent, and the
retiring Collateral Agent shall be discharged from its duties and obligations
hereunder. After any

                                      33
<PAGE>
 
retiring Collateral Agent's resignation hereunder as Collateral Agent, the
provisions of this Article  shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as the
Collateral Agent.

          10.9   COLLATERAL MATTERS.

          (a)    Authority.  Each Lender authorizes and directs the Collateral
                 ---------                                                    
Agent to enter into the Loan Documents relating to the Collateral for the
benefit of the Lenders.  Each Lender agrees that any action taken by the
Collateral Agent in accordance with the provisions of this Agreement or the
other Loan Documents, and the exercise by the Collateral Agent of the powers as
are reasonably incidental thereto, shall be authorized and binding upon all of
the Lenders.  Without limiting the generality of the foregoing, the Collateral
Agent shall have the sole and exclusive right and authority to (i) execute and
deliver each Loan Document relating to the Collateral and accept delivery of
each such agreement delivered by the Borrowers; (ii) act as collateral agent for
the Lenders for purposes of the perfection of all security interests and Liens
created by such agreements and all other purposes stated therein, provided,
                                                                  -------- 
however, the Collateral Agent hereby appoints, authorizes and directs the
- -------                                                                  
Lenders to act as collateral sub-agents for the Collateral Agent and the Lenders
for purposes of the perfection of all security interests and Liens with respect
to any of the Collateral held by such Lenders; (iii) manage, supervise and
otherwise deal with the Collateral; (iv) take such action as is necessary or
desirable to maintain the perfection and priority of the security interest and
Liens created or purported to be created by the Loan Documents, and (v) except
as may be otherwise specifically restricted by the terms of this Agreement or
any other Loan Document, exercise all remedies given to the Collateral Agent
with respect to the Collateral under the Loan Documents, Applicable Law or
otherwise.

          (b)    Each Lender hereby directs, in accordance with the terms of
this Agreement, the Collateral Agent to release or to subordinate any Lien held
by the Collateral Agent for the benefit of the Lenders:

                 (i)       against all of the Collateral upon final and
     indefeasible payment in full of the Obligations and the termination of this
     Agreement;

                 (ii)      against any part of the Collateral to which the
     Pledgor is entitled to have released pursuant to the terms of the Stock
     Pledge Agreement executed by such Pledgor;

                 (iii)     against any part of the Collateral constituting
     property in which the Borrower owned no interest at the time the Lien was
     granted or at any time thereafter; or

                 (iv)      if approved, authorized or ratified in writing by the
     Collateral Agent at the direction of all of the Lenders.

                                      34
<PAGE>
 
Each Lender hereby directs the Collateral Agent to execute and deliver or file
such termination and partial release statements and do such other things as are
necessary to release Liens to be released pursuant to Section  hereof promptly
upon the effectiveness of any such release.

          (c)    Without in any manner limiting the Collateral Agent's
authority to act without any specific or further authorization or consent by the
Lenders (as set for in Section ), each Lender agrees to confirm in writing, upon
request by the Borrower, the authority to release Collateral conferred upon the
Collateral Agent under clauses (i) through (iv) of Section hereof. So long as no
Default or Event of Default is then continuing, upon receipt by the Collateral
Agent of any such written confirmation from the Lenders of its authority to
release any particular items or types of Collateral, and in any event upon any
sale and transfer of Collateral which is expressly permitted pursuant to the
terms of this Agreement or the applicable Loan Document, and upon at least five
(5) Business Days prior written request by the Pledgor, the Collateral Agent
shall (and is hereby irrevocably authorized by Lenders to) execute such
documents as may be necessary to evidence the release of the Liens granted to
the Collateral Agent for the benefit of Lenders pursuant to the Loan Documents
upon such Collateral; provided, that (i) the Collateral Agent shall not be
                      --------
required to execute any such document on terms which, in the Collateral Agent's
opinion, would expose the Collateral Agent to liability or create any obligation
or entail any consequence other that the release of such Liens without recourse
or warranty, and (ii) such release shall not in any manner discharge, affect or
impair the Obligations or any Liens upon (or obligations of the Borrower in
respect of) all interests retained by the Collateral, including without
limitation the proceeds of any sale, all of which shall continue to constitute
part of the Collateral.

          (d)    The Collateral Agent shall have no obligation whatsoever to the
Lenders or to any other Person to assure that the Collateral exists or is owned
by the Pledgor or is cared for, protected or insured or has been encumbered or
that the Liens granted to the Collateral Agent pursuant to this Agreement or any
of the Loan Documents have been properly or sufficiently or lawfully created,
perfected, protected or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights,
authorities and powers granted or available to the Collateral Agent in this
Section or in any of the Loan Documents, it being understood and agreed that in
respect of the Collateral, or in any act, omission or event related thereto, the
Collateral Agent may act in any manner it may deem appropriate, in its sole
discretion, given its own interest in the Collateral as one of the Lenders and
that the Collateral Agent shall have no duty or liability whatsoever to any
Lender.

          10.10  BORROWER NOT A BENEFICIARY.  The provisions of this Article
are solely for the benefit of the Collateral Agent and the Lenders and the
Borrower shall not have any right to rely on or enforce any of the provisions
hereof.  In performing its functions and duties under this Agreement, the
Collateral Agent shall act solely as the agent of the Lenders and does not
assume and shall not be deemed to have assumed any obligations or relationship
of agency, trustee or fiduciary with or for the Borrower.

                               11. MISCELLANEOUS

          11.1   WAIVER.  Each and every right and remedy granted to the
Lenders under this Agreement, the other Loan Documents or any other document
delivered hereunder or in connection herewith or allowed it by law or in equity,
shall be cumulative and may be exercised from time to time.  No failure on the
part of either or both of the Lenders to exercise, and no delay in exercising,
any right or remedy shall operate as a waiver thereof, nor shall any single or
partial exercise by either or both of the Lenders of any right or remedy
preclude any other or future exercise thereof or the exercise of any other right
or remedy.  No waiver by either or both of the Lenders of any Default or Event
of Default shall constitute a waiver of any subsequent Default or Event of
Default.

          11.2   SURVIVAL.  All representations, warranties and covenants made
herein shall survive the execution and delivery of all of the Loan Documents.
The terms and provisions of this Agreement shall continue in full force and
effect until all of the Obligations have been paid in full and all obligations
of the Lenders hereunder to make Loans have terminated, whichever last occurs;
provided, further, that Obligors' obligations under Sections 2.3(c), 3.4, 3.5,
- --------  -------
11.5 and 11.14 shall survive the repayment of the Obligations and the
termination of this Agreement.

          11.3   ASSIGNMENTS; SUCCESSORS AND ASSIGNS.

          (a)    This Agreement and the Loan Documents shall be binding upon,
and inure to the benefit of, the successors of each of the Lenders, the
permitted successors of Borrowers and Pledgor, and the respective assigns,
transferees and endorsees of Lenders. No Person shall be deemed to be a third-
party beneficiary of any of the provisions of this Agreement or the Loan
Documents or otherwise have any rights by reason of any provisions of this
Agreement or the Loan Documents.

          (b)    Either or both of the Lenders may, in accordance with
Applicable Law, at any time sell to one or more banks or other financial
institutions ("Participants") participating interests in any Loans owing to the
Lenders, any of the Notes held by the Lenders, or any other interests of the
Lenders hereunder. Borrower agrees that each Participant shall be entitled to
the benefits of Section 2.3(c), 3.4, 3.5 and 11.14 with respect to its
participation; provided that no Participant shall be entitled to receive any
               -------- ----
greater amount pursuant to such Section than the Lender would have been entitled
to receive in respect of the amount of the participation transferred by that
Lender to such Participant had no such transfer occurred.

          (c)    Either of the Lenders may, in accordance with Applicable Law,
at any time assign, without the Obligors' consent, to one or more banks or
financial institutions having unimpaired capital and surplus of Two Hundred
Fifty Million Dollars ($250,000,000) or more or may assign with the Borrower's
consent (which shall not be unreasonably withheld) to any other Person (in
either case, "Assignees") all or any part of any Loans owing to the Lenders,

                                      36
<PAGE>
 
the Note held on behalf of the Lenders or any other interest of the Lenders
hereunder.  The Obligors and the Lenders agree that to the extent of any
assignment the Assignee shall be deemed to have the same rights and benefits
with respect to the Obligors under this Agreement and the Notes as it would have
had if it were one of the "Lenders" hereunder on the date hereof and the
assigning Lender shall be released from its obligations hereunder to the extent
of such assignment.

          (d)    Each Obligor authorizes the Lenders to disclose to any
Participant or Assignee ("Transferee") and any prospective Transferee any and
all financial information in the Lenders' possession concerning such Obligor
which has been delivered to the Lenders by such Obligor pursuant to this
Agreement or which has been delivered to the Lenders by such Obligor in
connection with the Lenders' credit evaluation of such Obligor prior to entering
into this Agreement.

          (e)    The Lenders shall be entitled to have any Note subdivided in
connection with a permitted assignment of all or any portion of such Note and
the respective Loans evidenced thereby pursuant to Section  above.  In the case
of any such subdivision, the new Note (the "New Note") issued in exchange for a
Note (the "Old Note") previously issued hereunder (i) shall be dated the date of
such assignment, (ii) shall be otherwise duly completed and (iii) shall bear a
legend, to the effect that such New Note is issued in exchange for such Old Note
and that the indebtedness represented by such Old Note shall not have been
extinguished by reason of such exchange.  Upon delivery of the New Note, the Old
Note shall be marked cancelled and returned to Borrowers.

          (f)    If, pursuant to this Section , any interest in this Agreement
or any Note is transferred to any Transferee which is organized under the laws
of any jurisdiction other than the United States or any State thereof, the
Lender making such transfer shall cause such Transferee, concurrently with the
effectiveness of such transfer, (i) to represent to the Borrowers and the
Lenders that under Applicable Law and treaties no taxes will be required to be
withheld by Borrowers or Lenders with respect to any payments to be made to such
Transferee hereunder or in respect of the Loans, (ii) to furnish to Lenders and
Borrowers either United States Internal Revenue Service Form 4224 or United
States Internal Revenue Service Form 1001 (wherein such Transferee claims
entitlement to complete exemption from United States federal withholding tax on
all payments hereunder) and (iii) to agree (for the benefit of Lenders and
Borrowers) to provide Lenders and Borrowers a new Form 4224 or Form 1001 upon
the obsolescence of any previously delivered form and comparable statements in
accordance with applicable United States laws and regulations and amendments
duly executed and completed by such Transferee, and to comply from time to time
with all applicable United States laws and regulations with regard to such
withholding tax exemption.

          (g)    No Obligor shall be permitted to assign its interest in this
Agreement or any Loan Document without the prior written consent of the Lenders.

                                      37
<PAGE>
 
          (h)    In addition to the assignments and participations permitted
under the foregoing provisions of this Section , (i) Creditanstalt or its parent
may assign and pledge all or any portion of its Loans and its Notes to any
Federal Reserve Lender as collateral security pursuant to Regulation A and any
Operating Circular issued by such Federal Reserve Lender and (ii) Kellett may
assign and pledge all or any portion of its Loans and its Notes to any financial
institution which may be financing Kellett's obligations hereunder. No such
assignment shall release the assignee from its obligations hereunder.

          11.4   COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which when fully executed shall be an original, and all of
said counterparts taken together shall be deemed to constitute one and the same
agreement.  Any signature page to this Agreement may be witnessed by a telecopy
or other facsimile of any original signature page and any signature page of any
counterpart hereof may be appended to any other counterpart hereof to form a
completely executed counterpart hereof.

          11.5   EXPENSE REIMBURSEMENT.  The Obligors, jointly and severally,
agree to reimburse the Lenders for all of the Lenders' expenses incurred in
connection with the negotiation, preparation, execution, delivery, modification,

Pledge Agreement, the Warrant Agreement, and the other Loan Documents,
including, without limitation, audit costs, appraisal costs, the cost of

and disbursements) to:  (a) commence, defend or intervene in any court
proceeding; (b) file a petition, complaint,  answer, motion or other pleading,
or to take any other action in or with respect to any suit or proceeding
(bankruptcy or otherwise) relating to the Collateral, or this Agreement, the
Notes or any of the other Loan Documents; (c) protect, collect, lease, sell,
take possession of, or liquidate any of the Collateral; (d) attempt to enforce
any Lien in any of the Collateral or to seek any advice with respect to such
enforcement; and (e) enforce any of the Lenders' rights to collect any of the
Obligations.  Obligors also agree, jointly and severally, to pay, and to save
harmless the Lenders from any delay in paying, any intangibles, documentary
stamp and other taxes, if any, which may be payable in connection with the
execution and delivery of this Agreement, the Notes, or any of the other Loan
Documents, or the recording of any thereof, or in any modification hereof or
thereof.  Additionally, the Obligors, jointly and severally, agree to pay to the
Lenders on demand any and all fees, costs and expenses which the Lenders pays to
a bank or other similar institution arising out of or in connection with (i) the
forwarding to Obligors, or any of them, or any other Person, on behalf of
Obligors, or any of them, by the Lenders of proceeds of any Loan and (ii) the
depositing for collection by the Lenders of any check or item of payment
received by or delivered to the Lenders on account of the Obligations.  The
Obligors' obligations under this Section  shall survive the termination of this
Agreement and the repayment of the Obligations.

Agreement or such Loan Document and the application of such provisions to any
other party thereto or circumstance shall not be affected thereby and shall be
enforced to the greatest extent permitted by law.

          11.7   NOTICES.  Except as otherwise provided herein, all notices,

except pursuant to a written instrument signed by Obligors and the Lenders.

          11.9   TIME OF THE ESSENCE.  Time is of the essence in this Agreement

          11.10  REINSTATEMENT.  This Agreement shall continue to be

intervenor or conservator of, or custodian, trustee or similar officer for,
either of the Borrowers, any of the other Obligors, or their Affiliates or any
part of any of those parties' property, or otherwise, all as though such

construed against or interpreted to the disadvantage of any party hereto by any
court or other Governmental Authority by reason of such party having or being
deemed to have structured or dictated such provision.

          11.12  LENDERS NOT JOINT VENTURERS.  Neither this Agreement, the
Loan Documents, any agreements, instruments, documents executed and delivered
pursuant hereto or thereto or in connection herewith or therewith, nor any of
the transactions contemplated hereby

                                      39

therewith including, without limitation, for payment on mortgage or note
obligations, for the purchase of insurance, the payment of taxes and the removal
or settlement of Liens and claims, shall be included in the Obligations and be
secured by the Collateral.

          11.14  INDEMNITY.  In addition to any other indemnity provided for
herein, the Obligors, jointly and severally, hereby indemnify the Lenders from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever (including, without limitation, fees and disbursements of
counsel) which may be imposed on, incurred by, or asserted against either of the
Lenders in any litigation, proceeding or investigation instituted or conducted
by any Governmental Authority or any other Person (other than the Obligors) with
respect to any aspect of, or any transaction contemplated by, or referred to in,
or any matter related to, this Agreement or the other Loan Documents, whether or

SPECIFICALLY WITH ITS RESPECTIVE COUNSEL, EACH OBLIGOR AND EACH OF THE LENDERS
