ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Under Section 145 of the Delaware General Corporation Law the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933. The Registrant's Bylaws (Exhibit 3.2 hereto) provide that the
Registrant shall indemnify its directors and officers to the fullest extent
permitted by Delaware law. The Bylaws require the Registrant, subject to certain
limitations, to advance litigation expenses in the case of stockholder
derivative actions or other actions, against an undertaking by the directors and
officers to repay such advances if it is ultimately determined that the
directors or officers are not entitled to indemnification. The Bylaws further
provide that rights conferred under such Bylaws shall not be deemed to be
exclusive of any other right such persons may have or acquire under any
agreement, vote of stockholders or disinterested directors, or otherwise. The
Registrant believes that indemnification under its Bylaws covers at least
negligence and gross negligence.
 
     In addition, the Registrant's Certificate (Exhibit 3.1 hereto) provides
that the Registrant shall indemnify its directors and officers if such persons
acted (i) in good faith, (ii) in a manner reasonably believed to be in or not
opposed to the best interests of the Registrant, and (iii) with respect to any
criminal action or proceeding, with reasonable cause to believe such conduct was
lawful. The Certificate also provides that, pursuant to Delaware law, its
directors shall not be liable for monetary damages for breach of the directors'
fiduciary duty of care to the Registrant and its stockholders. This provision in
the Certificate does not eliminate the duty of care, and in appropriate
circumstances equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the Registrant for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for actions
leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Certificate further provides that the
Registrant is authorized to indemnify its directors and officers to the fullest
extent permitted by law through the Bylaws, agreement, vote of stockholders or
disinterested directors, or otherwise.
 
                                      II-1

     The Registrant intends to obtain directors' and officers' liability
insurance in connection with the Offering.
 
     In addition, the Registrant has entered or, concurrently with the Offering,
will enter, into agreements to indemnify its directors and certain of its
officers in addition to the indemnification provided for in the Certificate of
Incorporation and Bylaws. These agreements will, among other things, indemnify
the Registrant's directors and certain of its officers for certain expenses
(including attorneys fees), judgments, fines and settlement amounts incurred by
such person in any action or proceeding, including any action by or in the right
of the Registrant, on account of services by that person as a director or
officer of the Registrant or as a director or officer of any subsidiary of the
Registrant, or as a director or officer of any other company or enterprise that
the person provides services to at the request of the Registrant.
 
     The Underwriting Agreement (Exhibit 1.1 hereto) provides for
indemnification by the Underwriters of the Registrant and its officers and
directors, and by the Registrant of the Underwriters, for certain liabilities
arising under the Securities Act or otherwise.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     The following is a summary of transactions by the Registrant during the
last three years preceding the date of this Registration Statement involving
sales of the Registrant's securities that were not registered under the
Securities Act:
 
   
          1.  In November 1996 in connection with the Acquisition, the
     Registrant issued (i) 22,000 shares of Class A Preferred Stock and warrants
     to purchase 2,900,000 shares of Common Stock at an exercise price of
     $0.0002 per share to one accredited investor for an aggregate consideration
     of $22.0 million; (ii) 10,000 shares of Class B Preferred Stock to Bausch &
     Lomb in consideration for the payment of a portion of the purchase price
     for the assets of S-O ($10.0 million); (iii) 3,185 shares of Class C
     Preferred Stock and warrants to purchase 477,750 shares of Common Stock at
     an exercise price of $0.0002 per share to three accredited investors for an
     aggregate consideration of $3.2 million, which included the cancellation of
     indebtedness in the amount of $10,000; (iv) 50,000 shares of Common Stock
     and warrants to purchase 745,400 shares of Common Stock at an exercise
     price of $0.0002 per share to one accredited investor for an aggregate
     consideration of $1,000; and (v) warrants to purchase an aggregate of
     428,000 shares of Common Stock at an exercise price of $0.0002 per share
     granted to the Registrant's senior lenders and subordinated lenders in
     consideration for making loans to the Registrant and (vi) warrants to
     purchase an aggregate of 198,850 shares of Common Stock at an exercise
     price of $.0002 per share granted to Larkspur Capital Corporation. The
     foregoing issuances were exempt from the registration requirements of the
     Securities Act on the basis that such transactions did not involve any
     public offering. Larkspur Capital Corporation acted as placement agent for
     this transaction.
    
 
   
          2.  In January 1997, the Registrant granted performance stock options
     and executive stock options to certain members of the Company's senior
     management team for the purchase of up to an aggregate of 442,061 shares of
     Common Stock at an exercise price equal to $0.40 per share. The executive
     stock options are fully vested and the performance options will vest in
     full upon consummation of the Offering. In January 1997, the Registrant
     also granted options to purchase an aggregate of 214,200 shares of Common
     Stock to the Directors of the Registrant at an exercise price of $1.00 per
     share. Such options are fully-vested. In May 1997, the Registrant granted
     performance options to purchase an aggregate of 77,089 shares of Common
     Stock at an exercise price of $0.40 per share to certain other employees of
     the Registrant. Such options will vest in full upon consummation of the
     Offering. In August 1997, the Registrant granted stock options under the
     1997 Plan to certain employees of the Registrant at an exercise price per
     share equal to the initial public offering price. Such options vest in four
     equal annual installments commencing one year following the grant date.
     None of the optionees referred to in this Item 2 paid any cash
     consideration for these options. The grant of all of such options did not
     involve a "sale" of securities and, therefore, no registration was
     required. The issuance of Common Stock upon exercise of such options is
     exempt by reason of Section 4(2) of the Securities Act and Rule 701
     thereunder.
    
 
                                      II-2
<PAGE>   4
 
   
          3.  In August 1997, the Registrant amended its Certificate of
     Incorporation and Certificates of Designation to (i) reduce the authorized
     par value of the Registrant's Common Stock and Preferred Stock from $.01
     per share to $0.0001 per share and (ii) provide for the automatic
     conversion of a portion of the Registrant's Class A Preferred Stock and
     Class C Preferred Stock upon consummation of the Offering. The issuance of
     shares of Common Stock upon conversion of the mandatorily redeemable
     Preferred Stock in the Preferred Stock Conversion will not be registered
     under the Securities Act by reason of the exemption provided by Section
     3(a)(9) thereof.

ITEM 17. UNDERTAKINGS
 
     The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreements certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus as filed as
     part of this Registration Statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the Registrant pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
     part of this Registration Statement as of the time it was declared
     effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

notice in writing to the Secretary of the corporation. To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not less than 60 days nor more
than 90 days prior to the scheduled date of the meeting, regardless of any
postponement, deferral or adjournment of that meeting to a later date; provided,

was made.

         A stockholder's notice to the Secretary shall set forth (i) as to each

person on the date of such stockholder's notice and (d) any other information
relating to such person that is required to be disclosed in solicitations of
proxies for election of directors, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as
amended, or any successor statute thereto (including, without limitation, such
person's written consent to being named in the proxy statement as a nominee and
to serving as a director if elected); (ii) as to the stockholder giving notice
(a) the name and address, as such information appears on the corporation's
books, of such stockholder and any other stockholders known by such stockholder
to be supporting such nominee(s), (b) the class and number of shares of the
corporation which are beneficially owned by such stockholder and each other
stockholder known by such stockholder to be supporting such nominee(s) on the
date of such stockholders notice, (c) a representation that the stockholder is a
holder of record of stock of the corporation entitled to vote at such meeting
and intends to appear in person or by proxy at the meeting to nominate the
person or persons specified in the notice; and (iii) a description of all
arrangements or understandings between the stockholder and each nominee and
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the stockholder.

         Subject to the rights, if any, of the holders of any series of
preferred stock then outstanding, no person shall be eligible for election as a
director of the corporation unless nominated in accordance with the procedures
set forth in this Section 10. The chairman of the meeting shall, if the facts
warrant, determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by this Section 10 and if he should so
determine, he shall so declare to the meeting and the defective nomination shall
be disregarded.

         Section 11. At any meeting of the stockholders, only such business
shall be conducted as shall have been brought before the meeting (a) pursuant to
the corporation's notice of meeting, (b) by or at the direction of the Board or
(c) by any stockholder of the corporation who is a stockholder of record at the
time of giving of the notice provided for in this Bylaw, who shall be entitled
to vote at such meeting and who complies with the notice procedures set forth in
this Bylaw.

         For business to be properly brought before any meeting by a stockholder
pursuant to clause (c) of this Section 11, the stockholder must have given
timely notice thereof in writing to the Secretary of the corporation. To be
timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the corporation not less than 60 days nor
more than 90 days prior to the scheduled date of the annual meeting, regardless
of any postponement, deferral or adjournment of that meeting to a later date;
provided, however, that if less than 70 days' notice or prior public disclosure
of the date of the annual meeting is given or made to stockholders, notice by
the stockholder to be timely must be so delivered or mailed and received not
later than the close of business on the 10th day following the earlier of (i)
the day on which such notice of the date of the meeting was mailed or (ii) the
day on which such public disclosure was made.

         A stockholder's notice to the Secretary shall set forth as to each
matter the stockholder proposes to bring before an annual meeting of
stockholders (i) a description, in 500 words or less, of the business desired to
be brought before the annual meeting and the reasons for conducting such
business at the annual meeting, (ii) the name and address, as such information
appears on the corporation's books, of the stockholder proposing such business
and any other stockholders known by such stockholder to be supporting such
proposal, (iii) the class and number of shares of the corporation that are
beneficially owned by such stockholder and each other stockholder known by such
stockholder to be supporting such proposal on the date of such stockholder's
notice, (iv) a description, in 500 words or less, of any interest of the
stockholder in such proposal and (v) a representation that the stockholder is a
holder of record of stock of the corporation and intends to appear in person or
by proxy at the meeting to present the proposal specified in the notice.
Notwithstanding the foregoing, nothing in this Section 11 shall be interpreted
or construed to require the inclusion of information about any such proposal in
any proxy statement distributed by, at the direction of, or on behalf of, the
Board.

         The chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that the business was not properly brought before the
meeting and in accordance with the procedures prescribed by this Section 11, and
if he should so determine, he shall so declare to the meeting and any such
business not properly brought before the meeting shall not be transacted.
Notwithstanding the foregoing provisions of this Section 11, a stockholder shall
also comply with all applicable requirements of the Securities Exchange Act of
1934, as amended, and the rules and regulations thereunder with respect to the
matters set forth in this Section 11.

shall be elected at the annual meeting of the stockholders, except as provided
in Section 2 of this Article, and each director elected shall hold office until
his successor is elected and qualified. Directors need not be stockholders. At
each election of directors, the persons receiving the greatest number of votes,
up to the number of directors then to be elected, shall be the persons then
elected. The election of directors is subject to any provisions, not
inconsistent with law, contained in the certificate of incorporation relating
thereto, including any provisions for a classified board.

         Section 2. Vacancies and newly created directorships may be filled by a
majority of the directors then in office, though less than a quorum, or by a
sole remaining director, subject to the rights of holders of preferred stock, if
any. The directors so chosen shall serve for the remainder of the term of the

         Section 3. The business of the corporation shall be managed by or under
the direction of its Board, which may exercise all such powers of the
corporation and do all such lawful acts and things as are not by statute or by

exercised or done by the stockholders.

Secretary in like manner and on like notice on the written request of two
directors unless the Board consists of only one director, in which case special
meetings shall be called by the President, Chief Executive Officer or Secretary
in like manner and on like notice on the written request of the sole director. A
written waiver of notice, signed by the person entitled thereto, whether before
or after the time of the meeting stated therein, shall be deemed equivalent to
notice.

         Section 8. At all meetings of the Board, a majority of the directors
then in office shall constitute a quorum for the transaction of business, and
the act of a majority of the directors present at any meeting at which there is
a quorum shall be the act of the Board, except as may be otherwise specifically
provided by statute or by the certificate of incorporation. If a quorum shall

adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present.

         Section 9. Unless otherwise restricted by the certificate of

incorporation or these bylaws, members of the Board, or any committee designated
by the Board, may participate in a meeting of the Board, or any committee, by
means of conference telephone or similar communications equipment by means of

         In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board to act at the meeting in the place of any such
absent or disqualified member.

         Any such committee, to the extent provided in the resolution of the
Board, shall have and may exercise all the powers and authority of the Board in
the management of the business and affairs of the corporation, and may authorize

consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, recommending

the Board.

         Section 12. Each committee shall keep regular minutes of its meetings
and report the same to the Board when required.

compensation of directors. Director compensation may include, among other
things, payment of their expenses, if any, of attendance at each meeting of the
Board, payment of a fixed sum for attendance at each meeting of the Board or
payment of a stated salary as director. No such payment shall preclude any
director from serving the corporation in any other capacity and receiving
compensation therefor. Members of special or standing committees may be allowed
like compensation for attending committee meetings.

                              REMOVAL OF DIRECTORS

it shall not be construed to mean personal notice (except as provided in Section
7 of Article III of these bylaws), but such notice may be given in writing, by
mail, addressed to such director or stockholder, at his address as it appears on
the records of the corporation, with postage thereon prepaid, and such notice
shall be deemed to be given at the time when the same shall be deposited in the
United States mail. Notice to directors may also be given by telephone, telegram
or facsimile.

         Section 2. Whenever any notice is required to be given under the
provisions of the statutes or of the certificate of incorporation or of these
bylaws, a waiver thereof in writing, signed by the person or persons entitled to
said notice, whether before or after the time stated therein, shall be deemed
equivalent thereto. The written waiver need not specify the business to be
transacted at, nor the purpose of, any regular or special meeting of the
stockholders, directors, or members of a committee of directors. Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
when the person attends the meeting for the express purpose of objecting at the
beginning at the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.

                                    ARTICLE V

of stockholders shall choose a Chief Executive Officer, President, Secretary and
Chief Financial Officer and may choose Vice Presidents.

to have a certificate, signed by, or in the name of the corporation by, the
Chief Executive Officer or the President and the Secretary or Chief Financial
Officer of the corporation, certifying the number of shares owned by him or her

shares, the total amount of the consideration to be paid therefor, and the
amount paid thereon shall be specified.

         If the corporation shall be authorized to issue more than one class of
stock or more than one series of any class, the powers, designations,

each class of stock or series thereof and the qualification, limitations or
restrictions of such preferences and/or rights shall be set forth in full or

                                      -11-

<PAGE>   12



certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the Board may, in its discretion and
as a condition precedent to the issuance thereof, require the owner of such
lost, stolen or destroyed certificate or certificates, or his legal
representative, to advertise the same in such manner as it shall require and/or
to give the corporation a bond in such sum as it may direct as indemnity against
any claim that may be made against the corporation with respect to the

distribution or allotment of any rights, or entitled to exercise any rights in

other lawful action, the Board may fix, in advance, a record date, which shall
not be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,

                             REGISTERED STOCKHOLDERS

         Section 6. The corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive

         Section 1. Dividends upon the capital stock of the corporation, subject
to the provisions of the certificate of incorporation, if any, may be declared
by the Board at any regular or special meeting, pursuant to law. Dividends may
be paid in cash, in property, or in shares of the capital stock, subject to the
provisions of the certificate of incorporation.

         Section 2. Before payment of any dividend, there may be set aside out
of any funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purposes as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

                                     CHECKS

         Section 3. All checks or demands for money and notes of the corporation

                                   FISCAL YEAR

         Section 4. The fiscal year of the corporation shall be fixed by

thereof to be impressed or affixed or reproduced or otherwise.


                                 INDEMNIFICATION

         Section 6. The corporation shall, to the fullest extent authorized
under the laws of the State of Delaware, as those laws may be amended and
supplemented from time to time, indemnify its officers and directors made, or
threatened to be made, a party to an action or proceeding, whether criminal,
civil, administrative or investigative, by reason of being an officer or
director of the corporation or a predecessor corporation or, at the
corporation's request, a



                                      -13-

<PAGE>   14



director or officer of another corporation, provided, however, that the
corporation shall indemnify any such officer or director in connection with a
proceeding initiated by such officer or director only if such proceeding was
authorized by the Board of the corporation. The indemnification provided for in
this Section 6 shall: (i) not be deemed exclusive of any other rights to which
those indemnified may be entitled under any bylaw, agreement or vote of
stockholders or disinterested directors or otherwise, both as to action in their
official capacities and as to action in another capacity while holding such
office, (ii) continue as to a person who has ceased to be an officer or director
of the corporation, and (iii) inure to the benefit of the heirs, executors and
administrators of such a person. The corporation's obligation to provide
indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

         Expenses incurred by an officer or director of the corporation in
defending a civil or criminal action, suit or proceeding by reason of the fact
that he or she is or was an officer or director of the corporation (or was
serving at the corporation's request as a director or officer of another
corporation) shall be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of such officer or director to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by the
corporation as authorized by relevant sections of the General Corporation Law of
Delaware. Notwithstanding the foregoing, the officer's or director's of the
corporation shall not be required to advance such expenses to an officer or
director who is a party to an action, suit or proceeding brought by the
corporation and approved by a majority of the Board of the corporation which
alleges willful misappropriation of corporate assets by such officer or
director, disclosure of confidential information in violation of such officer's
or director's fiduciary or contractual obligations to the corporation or any
other willful and deliberate breach in bad faith of such officer's or director's
duty to the corporation or its stockholders.

         The foregoing provisions of this Section 6 shall be deemed to be a
contract between the corporation and each officer and director who serves in
such capacity at any time while this bylaw is in effect, and any repeal or
modification thereof shall not affect any rights or obligations then existing
with respect to any state of facts then or theretofore existing or any action,
suit or proceeding theretofore or thereafter brought based in whole or in part
upon any such state of facts.

         The Board in its discretion shall have power on behalf of the
corporation to indemnify any person, other than an officer or director, made a
party to any action, suit or proceeding by reason of the fact that he, his
testator or intestate, is or was an employee or agent of the corporation.

         To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been "fiduciaries" of any employee benefit plan of the corporation
which may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section 6, be


                                      -14-

interpreted as follows: an "other enterprise" shall be deemed to include such an
employee benefit plan, including without limitation, any plan of the corporation
which is governed by the Act of Congress entitled "Employee Retirement Income
Security Act of 1974," as amended from time to time; the corporation shall be
deemed to have requested a person to serve an employee benefit plan where the
performance by such person of his duties to the corporation also imposes duties
on, or otherwise involves services by, such person to the plan or participants
or beneficiaries of the plan; excise taxes assessed on a person with respect to
an employee benefit plan pursuant to such Act of Congress shall be deemed
"fines."

bylaws may be altered, amended or repealed or new bylaws may be adopted by the
stockholders or a majority of the Board, when such power is conferred upon the

         Re: Registration Statement on Form S-1 (Registration No. 333-34397)

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-1 (Registration
No. 333-34397) filed by Steri-Oss, Inc. (the "Company") with the Securities and
Exchange Commission on August 26, 1997 (the "Registration Statement"), in
connection with the registration under the Securities Act of 1933, as amended,
of up to 5,405,000 shares of Common Stock, $.0001 par value (the "Shares") which
includes an over-allotment option granted to the Underwriters to purchase
additional Shares. The Shares are to be sold to the Underwriters as described in
the Registration Statement for resale to the public. As your counsel in
connection with this transaction, we have examined the proceedings taken and are
familiar with the proceedings proposed to be taken by you in connection with the
sale and issuance of the Shares.

         It is our opinion that, upon conclusion of the proceedings being taken
or contemplated by us to be taken prior to the issuance of the Shares, and upon
completion of the proceedings being taken in order to permit the transactions to
be carried out in accordance with the securities laws of the various states
where required, the Shares, when issued and sold in the manner described in the
Registration Statement, will be legally issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to all references to our name wherever appearing
in such Registration Statement, including the Prospectus constituting a part
thereof, and any amendment thereto. Subject to the foregoing sentence, this
opinion is given as of the date hereof solely for your benefit and may not be
relied upon, circulated, quoted or otherwise referred to for any purpose without
our prior written consent.

                                            Very truly yours,



                                            BROBECK, PHLEGER & HARRISON LLP

         3. As security for the loans and other financial accommodations to be

character or amount of any asset or liability or item of income or expense is
required to be determined, or any accounting computation is required to be made,
for the purpose of this Agreement or the Related Documents, such determination
or calculation shall be made, to the extent applicable and except as otherwise
specified in this Agreement or such Related Document, on a consolidated basis so
as to include Subsidiaries of Borrower in each such calculation and in
accordance with GAAP; provided, however, that if any change in generally
accepted accounting principles from those applied in the preparation of the
financial statements referred to in Section 10.3 hereof is occasioned by the
promulgation of rules, regulations, pronouncements and opinions by or required
by the Financial Accounting Standards Board or the American Institute of
Certified Public Accountants (or successors thereto or agencies with similar
functions), the initial announcement of which change is made after the Closing
Date, results in a change in the method of calculation of financial covenants,
standards or terms found in Sections 1 or 11 hereof, the parties hereto agree to
enter into good faith negotiations in order to amend such provisions so as to
reflect such changes with the desired result that the criteria for evaluating
Borrower's financial condition shall be the same after such changes as if such
changes had not been made; and provided, further, that until such time as the
parties hereto agree upon such amendments, such financial covenants, standards
and terms shall be construed and calculated as though such change had not taken
place. When used herein, the term "financial statement" shall include the notes
and schedules thereto, if any.

         of this Agreement, each Lender agrees, severally on its own behalf and
         not jointly with any other Lender:

                  2.1.1. Revolving Loan Commitment. To make loans to Borrower
         (herein collectively called the "Revolving Loans" and individually
         called a "Revolving Loan") on a revolving basis from time to time
         before November 15, 2001 (herein called the "Revolving Loan Termination
         Date") in such amounts as Borrower from time to time may request up to
         its Pro Rata Share of the amount set forth in Schedule I (as reduced
         pursuant to this Agreement, including pursuant to Section 2.5) at such
         time.

                  The foregoing commitment of Lenders is herein called the
         "Revolving Loan Commitment."

                  2.1.2. Working Capital Commitment. To make loans to Borrower
         (herein collectively called the "Working Capital Loans" and
         individually called a "Working Capital Loan") on a revolving basis from
         time to time before November 15, 1999 or such later date as may be
         established pursuant to Section 2.2 (herein called the "Working Capital
         Loan Termination Date") in such amounts as Borrower from time to time
         may request up to its Pro Rata Share of the then existing Maximum
         Amount of the Working Capital Commitment at such time, provided,
         however, that (i) such Lender shall not be required to make any Working
         Capital Loan following the initial Working Capital Loan unless there
         shall be outstanding, at the time of such proposed Working Capital
         Loan, Term Loans in the full principal amount of the Term Loan
         Commitment then in effect and Revolving Loans in the full principal
         amount of the Revolving Loan Commitment then in effect; (ii) such
         Lender shall not be required to make any Working Capital Loan if, after
         giving effect to such Working Capital Loan, the aggregate Total WC
         Exposure would exceed the Maximum Amount of the Working Capital
         Commitment then in effect; and (iii) the initial Working Capital Loan
         shall not exceed $500,000.

                  The foregoing commitment of Lenders is herein called the
         "Working Capital Commitment."

                  2.1.3. Letter of Credit Commitment. To issue to an Issuer
         guaranties, 


                                       23
<PAGE>   37


         substantially in the form set forth in Exhibit A, or any other
         assurance of repayment acceptable to such Issuer which such Lender in
         its sole discretion may offer (each such guaranty or other assurance
         herein, together with any extension or renewals thereof, or guaranties
         issued by such Lender in substitution therefor from time to time,
         called an "LC Guaranty") of its Pro Rata Share of reimbursement
         obligations of Borrower arising under reimbursement agreements
         substantially in the form set forth in Exhibit B or such other form as
         is satisfactory to the Requisite Lenders (herein collectively called
         the "LC Reimbursement Agreements" and individually called an "LC
         Reimbursement Agreement"), in each case executed in connection with
         Permitted LCs; provided however, that such Lender shall not be required
         to issue any LC Guaranty if, after giving effect to such issuance,
         Total WC Exposure would exceed the Working Capital Commitment then in
         effect, and provided, further, that in no event shall the aggregate
         amount of reimbursement obligations of Borrower secured at any time
         pursuant to LC Guaranties exceed $1,000,000. All LC Guaranties shall
         expire on or before the Working Capital Loan Termination Date.

                  The foregoing commitment of Lenders is herein called the
         "Letter of Credit Commitment."

                  2.1.4. Term Loan Commitment. To make term loans to Borrower
         (herein collectively called the "Term Loans" and individually called a
         "Term Loan") on a non- revolving basis from time to time before
         November 15, 2002 (herein called the "Term Loan Termination Date") in
         such amounts as Borrower from time to time may request up to its Pro
         Rata Share of the amount set forth in Schedule II (as reduced pursuant
         to this Agreement, including pursuant to Section 2.7) at such time.

                  The foregoing commitment of Lenders is herein called the "Term
         Loan Commitment."

                  2.1.5. Capital Expenditure Loan Commitment. To make term loans
         to Borrower (herein collectively called the "Capital Expenditure Loans"
         and individually called a "Capital Expenditure Loan") on a
         non-revolving basis from time to time before November 15, 1999 in such
         amounts as Borrower from time to time may request up to its Pro Rata
         Share of the amount set forth in Schedule III (as reduced pursuant to
         this Agreement, including pursuant to Section 2.8) at such time, solely
         for the purpose of financing Borrower's purchase of Equipment.

                  The foregoing commitment of Lenders is herein called the
         "Capital Expenditure Loan Commitment."

         The Revolving Loans, the Working Capital Loans, the Term Loans and the
Capital Expenditure Loans are herein collectively called "Loans" and
individually called a "Loan."

         SECTION 2.2 Extension of Working Capital Loan Termination Date.
Borrower,

pursuant to a Working Capital Commitment Extension Request substantially in the
form set forth in Exhibit C (a "Working Capital Commitment Extension Request"),
delivered to the Administrative Agent not more than 120, nor less than 30,
Business Days prior to the then scheduled Working Capital Loan Termination Date,
may request Lenders to extend all or part (as specified in such Working Capital
Commitment Extension Request) of the Working Capital Commitment and the Letter

the anniversary of the then scheduled Working Capital Loan Termination Date (or,
if such date is not a Business Day, on the next succeeding Business Day). If no
Event of Default or Unmatured Event of Default has occurred and is continuing on
the then scheduled Working Capital Loan Termination Date, the Working Capital
Loan Termination Date shall be extended for an additional one year period as so
requested, but in no event beyond November 15, 2001.

         SECTION 2.3  Loan Requests; Settlement Procedures.

                  (a) With respect to borrowings comprised of Reference Rate
         Loans not exceeding an aggregate amount of $1,000,000 or less in a
         single day, Borrower shall give notice to the Collateral Agent of each
         such proposed borrowing by 10:00 A.M., Chicago time on the day of, or
         within five (5) Business Days prior to, the proposed Funding Date of
         such borrowing. With respect to borrowings comprised of Reference Rate
         Loans in an aggregate amount in excess of $1,000,000 in a single day,
         Borrower shall give notice to the Collateral Agent of each such
         proposed borrowing by 10:00 A.M., Chicago time no later than three (3)
         Business Days and no sooner than five (5) Business Days prior to, the
         proposed Funding Date of such borrowing. Each of the aforementioned
         notices may be oral and shall be confirmed in writing on or before the
         fifteenth Business Day of the first calendar month following the
         Funding Date of each such borrowing by delivery of a Borrowing
         Certificate to each Lender. With respect to borrowings comprised of
         LIBOR Rate Loans, Borrower shall deliver to each Lender written notice
         of each such proposed borrowing substantially in the form set forth on
         Exhibit D (each a "Notice of LIBOR Activity") by 10:00 A.M., Chicago
         time at least three (3) Business Days prior to, but in any event no
         more than five (5) Business Days prior to, the proposed Funding Date.
         Each oral or written notice, as the case may be, given pursuant to this
         Section 2.3(a) shall be irrevocable. Loans made on any Funding Date (x)
         in the case of Reference Rate Loans, shall be in an aggregate minimum
         amount of $105,000 and integral multiples of $5,000 in excess thereof
         and (y) in the case of LIBOR Rate Loans, shall be in an aggregate
         minimum amount of $1,000,000 and integral multiplies of $100,000 in
         excess thereof. Subject to receipt by Collateral Agent of the documents
         required under Section 12 with respect to such borrowing and the
         satisfaction of all other conditions precedent to such borrowing set
         forth in this Agreement, on the requested Funding Date the Collateral
         Agent shall pay over such funds by wire transfer to the Master Account
         (except that, with respect to the initial Loans, disbursement shall be
         according to instructions to be agreed upon by Lenders and Borrower on
         or prior to the Closing Date).

                  (b) No Lender Party shall incur any liability to Borrower in
         acting upon any 


                                       25


<PAGE>   39


         oral notice referred to above which such Lender Party believes in good
         faith to have been given by a duly authorized officer or other person
         authorized to borrow on behalf of Borrower or for otherwise acting in
         good faith under this Section 2.3 and, upon funding of any Loans by
         Collateral Agent or any Lender in accordance with this Agreement
         pursuant to any such oral notice, Borrower shall have effected a Loan
         hereunder.

                  (c) On or prior to 10:00 a.m. (Chicago time) on each Business
         Day on which it is asked to make an advance with respect to Loans,
         Collateral Agent shall advise each Lender by telephone or facsimile
         transmission of the requested Funding Date, the amount of such advance
         and the amount of such Lender's Pro Rata Share thereof. Each Lender
         shall pay to Collateral Agent the amount of such Lender's Pro Rata
         Share of such advance prior to 11:00 a.m. (Chicago time) on the
         proposed Funding Date. Provided that each Lender has made all payments
         required to be made by it hereunder, on or prior to 11:00 a.m. (Chicago
         time) on the next Business Day after receipt by Collateral Agent of any
         payments of principal with respect to the Loans and interest, fees and
         other amounts with respect to the Liabilities (the "Daily Settlement
         Date"), Collateral Agent shall pay to each Lender the amount of such
         Lender's Pro Rata Share of such payments. If any payment from any
         Lender to Collateral Agent or from Collateral Agent to any Lender is
         not, in fact, made by the party from whom payment is due, the other
         party shall be entitled to recover such corresponding amount on demand
         (which demand shall be promptly made) together with interest thereon at
         the Federal Funds Rate, for each day from the Funding Date or Daily
         Settlement Date on which such amount was due until such amount is paid.

         SECTION 2.4 Certain Waivers. Borrower waives presentment, demand for
payment, notice of dishonor and protest, notice of the creation of any of the
Liabilities and all other notices whatsoever to Borrower with respect to the
Liabilities except notices required under Section 13.1. The obligations of
Borrower under this Agreement and the Related Documents shall not be affected by
(a) the failure of any Lender Party, any of its successors or assigns or any
holder of the Notes or any of the Liabilities to assert any claim or demand or
to exercise or enforce any right, power or remedy against Borrower, any of its
Subsidiaries, Parent, Investor, the Collateral or otherwise, (b) any extension
or renewal for any period (whether or not longer than the original period) or
exchange of any of the Liabilities or the release or compromise of any
obligation of any nature of any Person with respect thereto, (c) the surrender,
release or exchange of all or any part of any property (including without
limitation the Collateral) securing payment, performance and observance of any
of the Liabilities or the compromise or extension or renewal for any period
(whether or not longer than the original period) of any obligations of any
nature of any Person with respect to any such property, and (d) any other act,
matter or thing (other than payment and satisfaction) which would or might, in
the absence of this provision, operate to release, discharge or otherwise
prejudicially affect the obligations of Borrower.

         SECTION 2.5 Reduction or Termination of the Revolving Loan Commitment.

                  (a) On each Revolving Loan Commitment Reduction Date, the
         Revolving Loan 


                                       26


<PAGE>   40


         Commitment in effect on such date shall be reduced by an amount equal
         to the sum of (i) the Revolving Loan Commitment Reduction Amount plus
         (ii) for each Revolving Loan Commitment Reduction Date occurring on
         January 1 of any year (commencing with January 1, 1998) on which there
         is $1,000 or zero in aggregate outstanding principal amount of all
         Working Capital Loans, an amount equal to the amount by which (x) the
         Revolving Loan Commitment as adjusted pursuant to the foregoing clause
         (i) exceeds (y) the daily average of the outstanding principal amount
         of the Revolving Loans for a period of 30 days preceding such Revolving
         Loan Commitment Reduction Date, plus the amount of any payments
         received by Borrower from Metalor during such 30 day period, rounded up
         to the nearest integral multiple of $50,000; provided, however, that
         prior to the termination of the Revolving Loan Commitment, the
         Revolving Loan Commitment shall at no time be less than $1,000. For
         purposes of the foregoing, "Revolving Loan Commitment Reduction Amount"
         shall mean the amount indicated with respect to the relevant Revolving
         Loan Commitment Reduction Date in Schedule I under the caption
         "Scheduled Reduction in Revolving Loan Commitment." Borrower shall not,
         in anticipation of any Revolving Loan Commitment Reduction Date, take
         any actions primarily intended to increase the amount specified in
         clause (y) above for such date. These actions could include, for
         example and not by way of limitation, prepayment or accelerated payment
         of Borrower's trade payables, other obligations or discretionary
         expenditures or making short term investments (whether with Revolving
         Loan proceeds or other available cash). Additionally, effective as of
         the date the amounts described in clauses (A), (B) and (C) below are
         required to be applied to the repayment of the Loans, the Revolving
         Loan Commitment shall be automatically and permanently reduced by the
         amount of all (A) Unapplied Insurance or Condemnation Proceeds, (B)
         Asset Sale Proceeds and (C) Equity Sale Proceeds.

                  (b) In addition to the mandatory reductions of the Revolving
         Loan Commitment under clause (a) above, Borrower may voluntarily from
         time to time on at least five Business Days' prior written irrevocable
         notice to Lender permanently reduce the amount of the Revolving Loan
         Commitment or terminate the Revolving Loan Commitment prior to the
         Revolving Loan Termination Date; provided, however, that no such notice
         may be given unless, prior to or contemporaneously with the effective
         date of such reduction or termination, the Working Capital Commitment
         and the Letter of Credit Commitment shall have been terminated pursuant
         to Section 2.6 or otherwise and the Capital Expenditure Loan Commitment
         shall have been terminated pursuant to Section 2.8 or otherwise and
         provided, further, that prior to the termination of the Revolving Loan
         Commitment, the Revolving Loan Commitment shall at no time be less than
         $1,000. Each such voluntary reduction of the Revolving Loan Commitment
         shall be in an aggregate amount of at least $100,000 and an integral
         multiple of $50,000. Borrower may terminate the Revolving Loan
         Commitment only upon payment in full of the Revolving Note and all
         amounts, if any, due pursuant to Section 2.11.

                  (c) The amount of each reduction of the Revolving Loan
         Commitment pursuant to clauses (a) and (b) above (other than reductions
         pursuant to clause (a) (i) above) shall 


                                       27

         be subtracted (as an additional reduction of the Revolving Loan
         Commitment) from the "Amount of Revolving Loan Commitment" set forth in
         Schedule I opposite each remaining period in the inverse order of such
         remaining periods beginning with the last such period and ending with
         the period which includes the date of such reduction; and, upon
         Borrower's request, the Collateral Agent shall deliver to Borrower a
         copy of Schedule I setting forth such revisions, which revised Schedule
         I shall become a part of this Agreement amending any and all previous
         versions of Schedule I, provided, however, that the failure of the
         Collateral Agent to provide such Schedule I shall not give rise to or
         result in any liability of any Lender Party.

         SECTION 2.6 Reduction or Termination of the Working Capital Commitment
and Letter of Credit Commitment.

                  (a) On the Working Capital Commitment Termination Date, the
         Working Capital Commitment and the Letter of Credit Commitment in
         effect on such date shall be reduced to zero. Additionally, effective
         as of the date the amounts described in clauses (i), (ii) or (iii)
         below are required to be applied to the repayment of the Loans, the
         Working Capital Commitment shall be automatically and permanently
         reduced by the amount of all (i) Unapplied Insurance or Condemnation
         Proceeds less the amount of any reduction in the Revolving Loan
         Commitment pursuant to Section 2.5(a)(A) and the amount of any
         reduction in the Capital Expenditure Loan Commitment pursuant to
         Section 2.8(a)(i), (ii) Asset Sale Proceeds less the amount of any
         reduction in the Revolving Loan Commitment pursuant to Section
         2.5(a)(B) and the amount of any reduction in the Capital Expenditure
         Loan Commitment pursuant to Section 2.8(a)(ii), and (iii) Equity Sale
         Proceeds less the amount of any reduction in the Revolving Loan
         Commitment pursuant to Section 2.5(a)(C) and the amount of any
         reduction in the Capital Expenditure Loan Commitment pursuant to
         Section 2.8(a)(iii).

                  (b) In addition to the mandatory reduction of the Working
         Capital Commitment under clause (a) above, Borrower may voluntarily
         from time to time on at least five Business Days' prior written
         irrevocable notice to Lender permanently reduce or terminate the amount
         of the Working Capital Commitment, any such reduction to be in an
         aggregate amount of at least $100,000 and an integral multiple of
         $50,000; provided, however, that no such notice may be given unless,
         prior to or contemporaneously with the effective date of such reduction
         or termination, the Capital Expenditure Loan Commitment shall have been
         terminated pursuant to Section 2.8 or otherwise and provided, further,
         that prior to the termination of the Working Capital Commitment, the
         Working Capital Commitment shall at no time be less than the greater of
         (i) LC Exposure at such time and (ii) $1,000. Borrower may terminate
         the Working Capital Commitment and the Letter of Credit Commitment only
         upon payment in full of the Working Capital Note and all amounts, if
         any, due pursuant to Section 2.11 and full and final release and return
         by the Issuer of all LC Guaranties to Lenders.

                  (c) The amount of each reduction of the Working Capital
         Commitment 


                                       28


<PAGE>   42


         pursuant to clauses (a) and (b) above shall be subtracted (as an
         additional permanent reduction of the Working Capital Commitment) from
         the Maximum Amount of the Working Capital Commitment then in effect and
         the reduced Maximum Amount of the Working Capital Commitment shall
         constitute the Maximum Amount of the Working Capital Commitment.

         SECTION 2.7 Reduction or Termination of the Term Loan Commitment.

                  (a) On each Term Loan Commitment Reduction Date, the Term Loan
         Commitment in effect on such date shall be reduced by an amount equal
         to the Term Loan Commitment Reduction Amount. For purposes of the
         foregoing, "Term Loan Commitment Reduction Amount" shall mean the
         amount indicated with respect to the relevant Term Loan Commitment
         Reduction Date in Schedule II under the caption "Scheduled Reduction in
         Term Loan Commitment." Additionally, effective as of the date the
         amounts described in clauses (i), (ii) and (iii) below are required to
         be applied to the repayment of the Loans, the Term Loan Commitment
         shall be automatically and permanently reduced by the amount of all (i)
         Unapplied Insurance or Condemnation Proceeds less the amount of any
         reduction in the Revolving Loan Commitment pursuant to Section
         2.5(a)(A), the Working Capital Commitment pursuant to Section 2.6(a)(i)
         and the Capital Expenditure Loan Commitment pursuant to Section
         2.8(a)(i), (ii) Asset Sale Proceeds less the amount of any reduction in
         the Revolving Loan Commitment pursuant to Section 2.5(a)(B), the
         Working Capital Commitment pursuant to Section 2.6(a)(ii) and the
         Capital Expenditure Loan Commitment pursuant to Section 2.8(a)(ii) and
         (iii) Equity Sale Proceeds less the amount of any reduction in the
         Revolving Loan Commitment pursuant to Section 2.5(a)(C), the Working
         Capital Commitment pursuant to Section 2.6(a)(iii) and the Capital
         Expenditure Loan Commitment pursuant to Section 2.8(a)(iii).

                  (b) In addition to the mandatory reductions of the Term Loan
         Commitment under clause (a) above, Borrower may voluntarily from time
         to time on at least five Business Days' prior written irrevocable
         notice to Lender permanently reduce the amount of or terminate the Term
         Loan Commitment prior to the Term Loan Termination Date; provided,
         however, that no such notice may be given unless, prior to or
         contemporaneously with the effective date of such reduction or
         termination, the Revolving Loan Commitment, Working Capital Commitment,
         the Letter of Credit Commitment and the Capital Expenditure Loan
         Commitment shall have been terminated pursuant to Section 2.5, 2.6, 2.8
         or otherwise. Each such voluntary reduction of the Term Loan Commitment
         shall be in an aggregate amount of at least $100,000 and an integral
         multiple of $50,000. Borrower may terminate the Term Loan Commitment
         only upon payment in full of the Term Note and all amounts, if any, due
         pursuant to Section 2.11.

                  (c) The amount of each reduction of the Term Loan Commitment
         pursuant to clauses (a) and (b) above (other than Term Loan Commitment
         Reduction Amounts) shall be subtracted (as an additional reduction of
         the Term Loan Commitment) from the "Amount of Term Loan Commitment" set
         forth in Schedule II opposite each remaining 


                                       29


<PAGE>   43


         period in the inverse order of such remaining periods beginning with
         the last such period and ending with the period which includes the date
         of such reduction; and, upon Borrower's request, the Collateral Agent
         shall deliver to Borrower a copy of Schedule II setting forth such
         revisions, which revised Schedule II shall become a part of this
         Agreement amending any and all previous versions of Schedule II;
         provided, however, that the failure of the Collateral Agent to provide
         such Schedule II shall not give rise to or result in any liability of
         any Lender Party.

         SECTION 2.8 Reduction or Termination of the Capital Expenditure Loan
Commitment.

                  (a) On each Capital Expenditure Loan Commitment Reduction
         Date, the Capital Expenditure Loan Commitment in effect on such date
         shall be reduced by the Capital Expenditure Loan Commitment Reduction
         Amount. For purposes of the foregoing, "Capital Expenditure Loan
         Commitment Reduction Amount" shall mean the amount indicated in
         Schedule III under the caption "Scheduled Reduction in the Capital
         Expenditure Loan Commitment." Additionally, effective as of the date
         the amounts described in clauses (i), (ii) or (iii) below are required
         to be applied to the repayment of the Loans, the Capital Expenditure
         Loan Commitment shall be automatically and permanently reduced by the
         amount of all (i) Unapplied Insurance or Condemnation Proceeds less the
         amount of any reduction in the Revolving Loan Commitment pursuant to
         Section 2.5(a)(A), (ii) Asset Sale Proceeds less the amount of any
         reduction in the Revolving Loan Commitment pursuant to Section
         2.5(a)(B), and (iii) Equity Sale Proceeds less the amount of any
         reduction in the Revolving Loan Commitment pursuant to Section
         2.5(a)(C).

                  (b) In addition to the mandatory reduction of the Capital
         Expenditure Loan Commitment under clause (a) above, Borrower may
         voluntarily from time to time on at least five Business Days' prior
         written irrevocable notice to Lender permanently reduce the amount of
         or terminate the Capital Expenditure Loan Commitment, any such
         reduction to be in an aggregate amount of at least $100,000 and an
         integral multiple of $50,000; provided, however, that no such notice
         may be given unless, prior to or contemporaneously with the effective
         date of such reduction or termination, the Revolving Loan Commitment
         shall have been terminated pursuant to Section 2.7 or otherwise.
         Borrower may terminate the Capital Expenditure Loan Commitment only
         upon payment in full of the Capital Expenditure Loan Note and all
         amounts, if any, due pursuant to Section 2.11.

                  (c) The amount of each reduction of the Capital Expenditure
         Loan Commitment pursuant to clauses (a) and (b) above (other than
         Capital Expenditure Loan Commitment Reduction Amounts) shall be
         subtracted (as an additional reduction of the Capital Expenditure Loan
         Commitment) from the "Amount of Capital Expenditure Loan Commitment"
         set forth in Schedule III opposite each remaining period in the inverse
         order of such remaining periods beginning with the last such period and
         ending with the period 


                                       30


<PAGE>   44


         which includes the date of such reduction; and, upon Borrower's
         request, the Collateral Agent shall deliver to Borrower a copy of
         Schedule III setting forth such revisions, which revised Schedule III
         shall become a part of this Agreement amending any and all previous
         versions of Schedule III; provided, however, that the failure of the
         Collateral Agent to provide such Schedule III shall not give rise to or
         result in any liability of any Lender Party.

         SECTION 2.9 Mandatory Prepayments.

                  (a) Concurrently with each reduction (including any
         termination) of the Revolving Loan Commitment (whether pursuant to
         Section 2.5 or otherwise), Borrower shall make a mandatory prepayment
         of the amount, if any, by which the unpaid principal amount of the
         Revolving Loans (after giving effect to any repayments thereof pursuant
         to Section 7.3), exceeds the then reduced amount of the Revolving Loan
         Commitment (and each such payment shall be accompanied by accrued
         interest on such principal amount and any Prepayment Premium required
         under Section 2.11).

                  (b) Concurrently with each reduction (including any
         termination) of the Working Capital Commitment (whether pursuant to
         Section 2.6 or otherwise), Borrower shall make a mandatory prepayment
         of the amount, if any, by which (i) Total WC Exposure (after giving
         effect to any repayments of the Working Capital Loans pursuant to
         Section 7.3) exceeds (ii) the then reduced amount of the Working
         Capital Commitment (and each such payment shall be accompanied by
         accrued interest on such principal amount and any Prepayment Premium
         required under Section 2.11).

                  (c) Concurrently with each reduction (including any
         termination) of the Term Loan Commitment (whether pursuant to Section
         2.7 or otherwise), Borrower shall make a mandatory prepayment of the
         amount, if any, by which the unpaid principal amount of the Term Loans
         exceeds the then reduced amount of the Term Loan Commitment (and each
         such payment shall be accompanied by accrued interest on such principal
         amount and any Prepayment Premium required under Section 2.11).

                  (d) Concurrently with each reduction (including any
         termination) of the Capital Expenditure Loan Commitment (whether
         pursuant to Section 2.8 or otherwise), Borrower shall make a mandatory
         prepayment of the amount, if any, by which the unpaid principal amount
         of the Capital Expenditure Loans (after giving effect to any repayments
         thereof pursuant to Section 7.3), exceeds the then reduced amount of
         the Capital Expenditure Loan Commitment (and each such payment shall be
         accompanied by accrued interest on such principal amount and any
         Prepayment Premium required under Section 2.11).

                  (e) If at any time Total WC Exposure shall exceed the Working
         Capital Commitment then in effect, Borrower shall make a mandatory
         prepayment of the Working Capital Loans (and each such prepayment shall
         be accompanied by accrued interest on such principal amount and/or
         cause a reduction in the Cap Amount then in effect (by the 


                                       31


<PAGE>   45


         delivery of cash collateral to the applicable Issuer or otherwise) in
         the aggregate amount of such excess; provided, however, that any such
         reduction in the Cap Amount shall not be deemed effective for the
         purposes hereof until the applicable Issuer shall have delivered to
         Lenders a written acknowledgment thereof.

                  (f) If at any time the making of a deemed Loan pursuant to the
         first sentence of Section 7.5(b) results in Loans or Reimbursement
         Obligations exceeding the related Commitment, then Borrower immediately
         shall make a mandatory prepayment thereof (and each such payment shall
         be accompanied by accrued interest on such principal amount).

                  (g) Upon receipt by Borrower, any of its Subsidiaries or
         Parent of any Unapplied Insurance or Condemnation Proceeds, Asset Sale
         Proceeds or Equity Sale Proceeds, Borrower shall make a mandatory
         prepayment of the Loans in the amount thereof, each such prepayment to
         be applied in the order set forth in Section 7.3 (and each such payment
         shall be accompanied by accrued interest on such principal amount and
         any payment required under Section 2.11).

         SECTION 2.10 Voluntary Prepayments. Borrower voluntarily from time to
time may prepay the Loans in whole or in part, provided that:

                  (a) any prepayment of the Term Loan may be made only if at the
         time of such prepayment and after application of other payments being
         made at the same time the aggregate outstanding principal amount of all
         Revolving Loans and all Working Capital Loans is $1,000 or zero and no
         Reimbursement Obligations are outstanding;

                  (b) any prepayment of Revolving Loans may be made only if at
         the time of such prepayment and after application of other payments
         being made at the same time the aggregate outstanding principal amount
         of all Working Capital Loans is $1,000 or zero and no Reimbursement
         Obligations are outstanding;

                  (c) any prepayment of Working Capital Loans may be made only
         if at the time of such prepayment and after application of other
         payments being made at the same time no Reimbursement Obligations are
         outstanding;

                  (d) except for prepayments pursuant to Section 7.3, Borrower
         shall give Collateral Agent not less than five (5) Business Days' prior
         notice of any prepayment, specifying the Loans to be prepaid, and the
         date and amount of such prepayment;

                  (e) prior to the termination of the Working Capital
         Commitment, Borrower shall be entitled to prepay only so much of the
         Working Capital Loans as shall leave at all times outstanding a minimum
         principal amount of $1,000 in Working Capital Loans;

                  (f) prior to the termination of the Revolving Loan Commitment,
         Borrower 


                                       32


<PAGE>   46


         shall be entitled to prepay only so much of the Revolving Loans as
         shall leave at all times outstanding a minimum principal amount of
         $1,000 in Revolving Loans;

                  (g) except for prepayments pursuant to Section 7.3, each
         partial prepayment of a Loan shall be in a principal amount of at least
         $100,000 and an integral multiple of $50,000; and

                  (h) each such prepayment shall be accompanied by accrued
         interest on the principal amount prepaid and any Prepayment Premium
         required under Section 2.11.

         SECTION 2.11 Prepayment Premium. Each voluntary reduction of the
Commitments pursuant to Sections 2.5(b), 2.6(b), 2.7(b) and 2.8(b) and each
prepayment of all or any portion of the outstanding principal balance of the
Loans made from any source of funds other than funds derived in the ordinary
course of Borrower's business operations, including funds from any refinancing
of the Liabilities, from Asset Sale Proceeds, from Equity Sale Proceeds (other
than any Equity Sale Proceeds payable in respect of an initial public offering
of any Parent Equity Interests or any additional cash capital contribution to
Borrower by B&L or Investor) or from Unapplied Insurance or Condemnation
Proceeds, shall be accompanied in each case by a prepayment premium ("Prepayment
Premium") in an amount equal to:

                  (a) if such reduction or prepayment is made at any time during
         the period from and including the Closing Date to but excluding the
         first anniversary of the Closing Date, one and one-half of one percent
         (1.50%) of such reduction or prepayment;

                  (b) if such reduction or prepayment is made at any time during
         the period from and after the first anniversary of the Closing Date to
         but excluding the second anniversary of the Closing Date, one percent
         (1.00%) of such reduction or prepayment; and

                  (c) if such reduction or prepayment is made at any time during
         the period from and after the second anniversary of the Closing Date to
         but excluding the third anniversary of the Closing Date, one-half of
         one percent (0.50%) of such reduction or prepayment.

         SECTION 2.12 Making of Payments. All payments of principal of, or
interest on, the Notes and of all fees and other Liabilities shall be made by
Borrower to Collateral Agent in immediately available Dollars. All such payments

Bank, ABA #071000505 (or such other account as Collateral Agent may specify from
time to time), not later than 12:30 P.M., Chicago time, on the date due; and
funds received after that hour shall be deemed to have been received by
Collateral Agent on the next following Business Day. Anything in this Agreement
to the contrary notwithstanding, under no circumstances shall receipt by Agent
Bank of funds of Borrower (prior to transfer of such funds to Collateral Agent
in accordance with the Bank Agency Agreement) constitute repayment of Loans or
entitle Borrower to interest thereon.

<PAGE>   47


         SECTION 2.13 Due Date Extension. If any payment of principal or
interest with respect to any of the Loans or Reimbursement Obligations falls due
on a Saturday, Sunday or other day which is not a Business Day, then such due
date shall be extended to the next following Business Day, and additional
interest shall accrue and be payable for the period of such extension.

         SECTION 2.14 Setoff. Collateral Agent, Administrative Agent, Agent Bank
(all as agents of Lenders), each Lender shall have all rights of set-off
provided by applicable law, and in addition thereto, if at any time any payment
or amount owing by Borrower under or in connection with this Agreement or the
Related Documents is then due, Collateral Agent, Administrative Agent, Agent
Bank (all as agents for Lenders), each Lender may apply to the payment of such
payment or other amount any and all balances, credits, deposits, accounts or
moneys of Borrower then or thereafter with such Person.

         SECTION 2.15 Certain Matters Relating to LC Guaranties.

                  2.15.1. Reimbursement Obligation. Notwithstanding any
         provision herein to the contrary, immediately upon any Issuer's
         presentation of any demand for payment under an LC Guaranty, Borrower
         shall be obligated to reimburse each Lender for such Lender's Pro Rata
         Share of such demand, on the date on which such Lender honors its Pro
         Rata Share of such demand, in immediately available funds equal to the
         amount of such honored demand (such obligations being referred to
         herein as "Reimbursement Obligations"). Each Lender shall use its best
         efforts to give notice to Borrower of the amount of such honored demand
         by such Lender, provided, however, that the failure to give such notice
         shall not relieve Borrower of its Reimbursement Obligation nor give
         rise to or result in any liability of any Lender. If all or any part of
         such demand is not paid by Borrower within two Business Days after
         notice from Collateral Agent, such unpaid amount shall bear interest
         for each day during the period from the day of such demand until it
         shall be paid in full at a rate equal to the Default Rate applicable to
         Working Capital Loans which are Reference Rate Loans. Pursuant to a
         written notice within five (5) Business Days prior to, or
         contemporaneously with, Borrower's incurrence of a Reimbursement
         Obligation, Borrower may request that such Reimbursement Obligation be
         converted into a Working Capital Loan. Such Reimbursement Obligation
         shall be so converted if, and only if, each of the following conditions
         shall have been satisfied within three (3) Business Days after the date
         the Reimbursement Obligation is incurred: (a) no Event of Default or
         Unmatured Event of Default shall have occurred and be continuing, (b)
         after giving effect to such conversion, Total WC Exposure shall not
         exceed the Working Capital Commitment then in effect, (c) all other
         conditions precedent to the making of a Working Capital Loan shall be
         satisfied, other than any requirement that the amount of such Loan
         shall be in a minimum amount of $105,000 or an integral multiple of
         $5,000, and (d) an appropriate officer of Borrower shall have delivered
         a certificate confirming satisfaction of each of the conditions
         specified in clauses (a), (b) and (c) above. Such conversion shall be
         effective on the date on which all of the conditions specified in the
         preceding sentence are satisfied, and thereafter each reference in this
         Agreement or any other Related Document to a Loan or Loans shall be
         deemed to include

         reference to such Reimbursement Obligations as so converted.

                  2.15.2. Reimbursement Obligations Absolute. The obligation of
         Borrower to reimburse a Lender for demands made under the LC Guaranties
         shall be unconditional and irrevocable and shall be enforced strictly
         in accordance with the terms of this Agreement under all circumstances,
         including, without limitation, the following:

                  (a) lack of validity or enforceability of the applicable LC
         Guaranty or Permitted LC;

                  (b) the existence of any claim, set-off, defense (other than
         payment and performance) or other right which Borrower may have at any
         time against an Issuer, any other Lender Party or any other Person,
         whether in connection with this Agreement, the transactions
         contemplated herein or any unrelated transaction (including any
         underlying transaction between Borrower and the beneficiary under a
         Permitted LC);

                  (c) any draft, demand, certificate or any other document
         presented under an LC Guaranty or Permitted LC proving to be forged,
         fraudulent, invalid or insufficient in any respect or any statement
         therein being untrue or inaccurate in any respect;

                  (d) payment by any Lender under any LC Guaranty against a
         demand which does not comply with the terms of the LC Guaranty,
         provided that such payment does not constitute gross negligence or
         willful misconduct of such Lender;

                  (e) any adverse change in the condition (financial or
         otherwise) of Borrower;

                  (f) any breach of this Agreement by Borrower or any other
         Lender Party;

                  (g) any other circumstances or happening whatsoever, which is
         similar to any of the foregoing; or

                  (h) the fact that an Event of Default or an Unmatured Event of
         Default shall have occurred and be continuing.

                  2.15.3. Indemnification. In addition to amounts payable as
         elsewhere provided herein and to the provisions of Section 14.5 hereof,
         Borrower hereby agrees to indemnify, exonerate and hold each Lender
         Party free and harmless from and against any and all claims, demands,
         actions, causes of action, suits, losses, costs (including attorneys'
         fees and disbursements), charges, liabilities and damages, and expenses
         in connection therewith (irrespective of whether such Person is a party
         to the action for which indemnification hereunder is sought) which such
         Lender Party incurs or is subject to as a consequence, directly or
         indirectly, of (i) the issuance of any LC Guaranty, other than as a
         result of the gross negligence or willful misconduct of such Person as
         determined by a court of competent jurisdiction, or (ii) the failure of
         any Lender to honor a demand 


                                       35


<PAGE>   49


         under an LC Guaranty as a result of any act or omission relating to an
         LC Guaranty, whether rightful or wrongful, of any present or future de
         jure or de facto government or governmental authority (herein all such
         acts or omissions being called "Governmental Acts"). All obligations
         under this Section 2.15.3 shall survive any termination of this
         Agreement.

                  As among Borrower and Lender Parties, Borrower assumes all
         risks of the acts and omissions of, or misuse of an LC Guaranty by, the
         applicable Issuer or any beneficiary of a Permitted LC. Without
         limiting the foregoing, no Lender Party shall be responsible for: (i)
         the form, validity, sufficiency, accuracy, genuineness or legal effect
         of any document submitted by any Person in connection with the
         application for and issuance of an LC Guaranty or Permitted LC, even if
         such document is proven to be in any respect invalid, insufficient,
         inaccurate, fraudulent or forged; (ii) the validity or sufficiency of
         any instrument transferring or assigning or purporting to transfer or
         assign an LC Guaranty or Permitted LC or the rights or benefits
         thereunder or proceeds thereof, in whole or in part, which may prove to
         be invalid or ineffective for any reason; (iii) the failure of the
         beneficiary of a Permitted LC to comply fully with conditions required
         in order to draw thereupon, or the failure of an Issuer to comply fully
         with conditions required in order to demand under an LC Guaranty; (iv)
         errors, omissions, interruptions or delays in transmission or delivery
         of any messages, by mail, cable, telegraph, facsimile, telex or
         otherwise, whether or not they be in cipher; (v) errors in
         interpretation of technical terms; (vi) any loss or delay in the
         transmission or otherwise of any document required in order to make a
         drawing under a Permitted LC or a demand under an LC Guaranty or of the
         proceeds of either thereof; (vii) the misapplication by an Issuer of
         the proceeds of any demand under an LC Guaranty; and (viii) any
         consequences arising from causes beyond the control of such Lender
         Party, including, without limitation, any Governmental Acts, in each
         case, other than a result of the gross negligence or willful misconduct
         of such Lender Party. None of the above shall affect, impair or prevent
         the vesting of any of any Lender Party's rights or powers hereunder.

                  Without limiting the foregoing, any action taken or omitted by
         any Lender Party under or in connection with an LC Guaranty shall not
         put such Lender Party under any resulting liability to Borrower.

         SECTION 3 NOTES; RECORDKEEPING.

         SECTION 3.1 Revolving Note. The Revolving Loans shall be evidenced by
promissory notes (herein, as from time to time supplemented, extended or
replaced, collectively called the "Revolving Note") substantially in the form
set forth in Exhibit E, with appropriate insertions, dated the date hereof,
payable to the order of each Lender in the maximum principal amount of such
Lender's Pro Rata Share of the Revolving Loan Commitment.

         SECTION 3.2 Working Capital Note. The Working Capital Loans shall be
evidenced by promissory notes (herein, as from time to time supplemented,
extended or replaced, 


                                       36

collectively called the "Working Capital Note") substantially in the form set
forth in Exhibit F, with appropriate insertions, dated the date hereof, payable
to the order of each Lender in the maximum principal amount of such Lender's Pro
Rata Share of the Working Capital Commitment.

         SECTION 3.3 Term Note. The Term Loan shall be evidenced by promissory
notes (herein, as from time to time supplemented, extended or replaced,
collectively called the "Term Note") substantially in the form set forth in
Exhibit G, with appropriate insertions, dated the date hereof, payable to the
order of each Lender in the maximum principal amount of such Lender's Pro Rata
Share of the Term Loan Commitment.

         SECTION 3.4 Capital Expenditure Loan Note. The Capital Expenditure Loan
shall be evidenced by promissory notes (herein, as from time to time

Loan Note") substantially in the form set forth in Exhibit H, with appropriate

Expenditure Loan Commitment.

         SECTION 3.5 Recordkeeping. Collateral Agent shall record in its records
the date and amount of each Loan made hereunder, each repayment thereof, and the
other information provided for herein. The aggregate unpaid principal amount so
recorded shall be rebuttable presumptive evidence of the principal amount owing
and unpaid on the applicable Note. The failure so to record any such information
or any error in so recording any such information shall not, however, limit or
otherwise affect the actual obligations of Borrower hereunder or under the Notes
to repay the principal amount of all Loans together with all interest accruing
thereon.

         SECTION 4  INTEREST.

         SECTION 4.1 Interest Rates on Revolving Loans. Subject to Section 4.5,
Borrower hereby promises to pay interest on the outstanding principal amount of
each Revolving Loan for the period commencing on the date of such Loan until
such Loan is paid in full at a rate per annum determined by reference to the
Reference Rate or the LIBOR Rate. The applicable basis for determining the rate
of interest shall be selected by Borrower at the time a borrowing is requested
pursuant to Section 2.3(a) or at the time a Notice of LIBOR Activity is given
pursuant to Section 4.5, as the case may be. If a Revolving Loan is outstanding
with respect to which notice has not been given to Collateral Agent in
accordance with the terms of this Agreement specifying the basis for determining
the rate of interest, then such Revolving Loan shall be a Reference Rate Loan.
Subject to Section 4.5, all Revolving Loans shall bear interest as follows:

                  (a) if a Reference Rate Loan, then at the sum of the Reference
         Rate in effect from time to time, plus one and one-half of one percent
         (1.50%) per annum; or

                  (b) if a LIBOR Rate Loan, then at the sum of the LIBOR Rate
         for the 


                                       37

         applicable Interest Period, plus three percent (3.00%) per annum.

         SECTION 4.2 Interest Rates on Working Capital Loans. Subject to Section
4.5, Borrower hereby promises to pay interest on the outstanding principal
amount of each Working Capital Loan for the period commencing on the date of
such Working Capital Loan until such Working Capital Loan is paid in full at a
rate per annum determined by reference to the Reference Rate or the LIBOR Rate.
The applicable basis for determining the rate of interest shall be selected by
Borrower at the time a borrowing is requested pursuant to Section 2.3(a) or at
the time a Notice of LIBOR Activity is given by Borrower pursuant to Section
4.5, as the case may be. If a Working Capital Loan is outstanding with respect
to which notice has not been given to Collateral Agent in accordance with the
terms of this Agreement specifying the basis for determining the rate of
interest, then such Working Capital Loan shall be a Reference Rate Loan. Subject
to Section 4.5, all Working Capital Loans shall bear interest as follows:

                  (a) if a Reference Rate Loan, then at the sum of the Reference
         Rate in effect from time to time, plus one and one-half of one percent
         (1.50%) per annum; or

                  (b) if a LIBOR Rate Loan, then at the sum of the LIBOR Rate
         for the applicable Interest Period, plus two and three-quarters of one
         percent (2.75%) per annum.

         SECTION 4.3 Interest Rates on Term Loans. Subject to Section 4.5,
Borrower hereby promises to pay interest on the outstanding principal amount of
each Term Loan for the period commencing on the Closing Date until such Term
Loan is paid in full at a rate per annum determined by reference to the
Reference Rate or the LIBOR Rate. The applicable basis for determining the rate
of interest shall be selected by Borrower at the time a borrowing is requested
pursuant to Section 2.3(a) or at the time a Notice of LIBOR Activity is given
pursuant to Section 4.5, as the case may be. If a Term Loan is outstanding with
respect to which notice has not been given to Collateral Agent in accordance
with the terms of this Agreement specifying the basis for determining the rate
of interest, then such Term Loan shall be a Reference Rate Loan. Subject to
Section 4.5, all Term Loans shall bear interest as follows:

                  (a) if a Reference Rate Loan, then at the sum of the Reference
         Rate in effect from time to time, plus two percent (2.00%) per annum;
         or

                  (b) if a LIBOR Rate Loan, then at the sum of the LIBOR Rate
         for the applicable Interest Period, plus three and three-quarters of
         one percent (3.75%) per annum.

         SECTION 4.4 Interest Rates on Capital Expenditure Loans. Subject to
Section 4.5, Borrower hereby promises to pay interest on the outstanding
principal amount of each Capital Expenditure Loan for the period commencing on
the date of such Capital Expenditure Loan until such Capital Expenditure Loan is
paid in full at a rate per annum determined by reference to the Reference Rate
or the LIBOR Rate. The applicable basis for determining the rate of interest
shall be selected by Borrower at the time a borrowing is requested pursuant to
Section 2.3(a) or at the 


                                       38


<PAGE>   52


time a Notice of LIBOR Activity is given by Borrower pursuant to Section 4.5, as
the case may be. If a Capital Expenditure Loan is outstanding with respect to
which notice has not been given to Collateral Agent in accordance with the terms
of this Agreement specifying the basis for determining the rate of interest,

Section 4.5, all Capital Expenditure Loans shall bear interest as follows:

                  (a) if a Reference Rate Loan, then at the sum of the Reference
         Rate in effect from time to time, plus one and one-half of one percent
         (1.50%) per annum; or

                  (b) if a LIBOR Rate Loan, then at the sum of the LIBOR Rate
         for the applicable Interest Period, plus three percent (3.00%) per
         annum.

         SECTION 4.5 Default Interest.

                  (a) Notwithstanding the respective rates of interest specified
         in Sections 4.1, 4.2, 4.3 and 4.4, during any Default Interest Period
         the unpaid principal amount of all Loans shall bear interest at the
         applicable rate per annum set forth in Section 4.1, 4.2, 4.3 and 4.4,
         respectively, plus two percent (2.00%) per annum (each rate described
         in this clause (a) being herein called the "Default Rate").

                  (b) For purposes of this Section 4.5, the term "Default
         Interest Period" shall mean a period of time commencing on the date on
         which the Requisite Lenders notify Borrower that an Event of Default
         has occurred and ending on the date on which such Event of Default is
         cured or waived.

         SECTION 4.6 Conversion or Continuation.

                  (a) Subject to the provisions of Section 4.6, Borrower shall
         have the option (i) to convert at any time all or any part of its
         outstanding Loans equal to $1,000,000 and integral multiples of
         $100,000 in excess of that amount from a Reference Rate Loan to a LIBOR
         Rate Loan; (ii) to convert all or any part of its outstanding Loans in
         integral multiples of $100,000 from a LIBOR Rate Loan to a Reference
         Rate Loan on the expiration date of any Interest Period applicable
         thereto; or (iii) upon the expiration of the Interest Period with
         respect to any LIBOR Rate Loan, to continue all or any portion of such
         Loan equal to $1,000,000 and integral multiples of $100,000 in excess
         of that amount as a LIBOR Rate Loan, and the succeeding Interest
         Period(s) of such continued Loan shall commence on the expiration date
         of the Interest Period applicable thereto; provided, however, that,
         notwithstanding the foregoing, no outstanding Loan may be continued as,
         or be converted into, a LIBOR Rate Loan when any Event of Default or
         Unmatured Event of Default has occurred and is continuing without the
         consent of the Requisite Lenders.

                  (b) In the event Borrower shall elect to convert or continue a
         Loan under Section 4.6(a), Borrower shall deliver to Collateral Agent a
         Notice of LIBOR Activity by 


                                       39


<PAGE>   53


         10:00 A.M., Chicago time three (3) Business Days prior to, but in any
         event not more than five (5) Business Days prior to, the proposed
         conversion/continuation date. Upon conversion or continuation by
         Lenders in accordance with this Agreement pursuant to any Notice of
         LIBOR Activity, Borrower shall have effected the
         conversion/continuation of Loans hereunder.

                  (c) The officers and employees of Borrower authorized to
         request a Loan on behalf of Borrower shall also be authorized to
         request a conversion/continuation on behalf of Borrower. No Lender
         Party shall incur any liability to Borrower in acting upon any oral
         notice referred to above which such Lender Party believes in good faith
         to have been given by a duly authorized officer or other person
         authorized to act on behalf of Borrower or such other obligor or for
         otherwise acting in good faith under this Section 4.6.

                  (d) Any Notice of LIBOR Activity for conversion to, or
         continuation of, a Loan (including any such oral notice) shall be
         irrevocable and Borrower shall be bound to convert or continue in
         accordance therewith.

         SECTION 4.7 Special Provisions Governing LIBOR Rate Loans .
Notwithstanding anything to the contrary contained in this Agreement, the
following provisions shall govern with respect to LIBOR Rate Loans as to the
matters covered:

                  (a) Determination of Interest Period. By giving notice as set
         forth in Sections 2.3 or 4.6(b), Borrower shall have the option,
         subject to the other provisions of this Section 4.7, to specify whether
         the Interest Period applicable to any requested LIBOR Rate Loan shall
         be a one-month, three-month or six-month period. The determination of
         Interest Periods shall be further subject to the following provisions:

                           (i) In the case of immediately successive Interest
                  Periods, each successive Interest Period shall commence on the
                  day on which the immediately preceding Interest Period
                  expires.

                           (ii) If any Interest Period would otherwise expire on
                  a day which is not a Business Day, the Interest Period shall
                  be extended to expire on the next succeeding Business Day.

                           (iii) Borrower may not select an Interest Period for
                  any Revolving Loan which terminates later than November 15,
                  2001, for any Term Loan which terminates later than November
                  15, 2002, for any Working Capital Loan which terminates later
                  than the Working Capital Loan Termination Date then in effect
                  or for any Capital Expenditure Loan which terminates later
                  than November 15, 2002.

                           (iv) Borrower may not select an Interest Period with
                  respect to any portion of principal of a Loan which extends
                  beyond a date on which Borrower 


                                       40


<PAGE>   54


                  could reasonably be expected to be required to make a
                  mandatory payment or prepayment of that portion of principal
                  (including, without limitation, as a result of any mandatory
                  reduction in the Revolving Loan Commitment, the Working
                  Capital Commitment, the Term Loan Commitment or the Capital
                  Expenditure Loan Commitment, respectively, pursuant to the
                  terms of this Agreement).

                           (v) Any Interest Period which begins on a day for
                  which there is no numerically corresponding day in the
                  calendar month during which such Interest Period is to end
                  shall (subject to clause (ii) above) end on the first Business
                  Day following the last day of such calendar month.

                           (vi) There shall be no more than four (4) LIBOR Rate
                  Loans outstanding at any one time.

                  (b) Determination of Interest Rate. As soon as practicable on
         the second Business Day immediately preceding the first day of any
         Interest Period applicable to any LIBOR Rate Loans (the "LIBOR Interest
         Rate Determination Date"), Collateral Agent shall determine (which
         determination shall, absent manifest error, be presumptively correct)
         the interest rate which shall apply to such Loans for such Interest
         Period and shall promptly give notice thereof (in writing or by
         telephone confirmed in writing) to Borrower.

                  (c) Substituted Rate of Borrowing. In the event that on any
         LIBOR Interest Rate Determination Date any Lender shall have determined
         (which determination shall be presumptively correct and binding upon
         all parties) that, by reason of any changes arising after the date of
         this Agreement affecting the London interbank market, adequate and fair
         means do not exist for ascertaining the LIBOR Rate on a basis
         consistent with the essential intent of the parties hereto, then, and
         in any such event, the right of Borrower to select a LIBOR Rate Loan
         for such Loan or any subsequent Loan shall be suspended until such
         Lender shall notify Borrower that the circumstances causing such
         suspension no longer exist, and such requested Loan shall be a
         Reference Rate Loan.

                  (d) Illegality. Notwithstanding anything to the contrary
         contained in this Agreement, in the event that on any date any Lender
         shall have reasonably determined (which determination shall be final
         and conclusive and binding upon all parties) that the making or
         continuation of its LIBOR Rate Loans has become unlawful by compliance
         by such Lender in good faith with any applicable law, treaty,
         governmental rule, regulation or order (whether or not having the force
         of law and whether or not failure to comply therewith would be
         unlawful), then such Lender shall promptly give notice to Borrower of
         such determination. Subject to the prior withdrawal of a Notice of
         LIBOR Activity or prepayment of the LIBOR Rate Loans as contemplated by
         the following Section 4.7(e), the obligation of such Lender to make or
         maintain LIBOR Rate Loans during any such period shall be terminated at
         the earlier of the termination of the 


                                       41


<PAGE>   55


         Interest Period then in effect or when required by law, and Borrower
         shall no later than the termination of the Interest Period in effect at
         the time any such determination pursuant to this Section 4.7(d) is made
         or, earlier, when required by law, repay the LIBOR Rate Loans, together
         with all interest accrued thereon. Each Lender shall use reasonable
         efforts to avoid the possibility that the making or continuation of its
         LIBOR Rate Loans shall become unlawful.

                  (e) Options of Borrower. In lieu of prepaying LIBOR Rate Loans
         as required by Section 4.7(d) above, Borrower may exercise either of
         the following options:

                           (i) Upon written notice to Collateral Agent, Borrower
                  may terminate the obligations of the affected Lender to make
                  or maintain Loans as, and to convert Loans into, LIBOR Rate
                  Loans and in such event, Borrower shall, at the end of the
                  then current Interest Period (or at such earlier time as
                  prepayment is otherwise required), convert all of the LIBOR
                  Rate Loans of such Lender into Reference Rate Loans in the
                  manner contemplated by Section 4.6 but without satisfying the
                  advance notice requirements therein; or

                           (ii) Borrower may, by giving notice (by telephone
                  confirmed immediately by telecopy) to Collateral Agent require
                  such Lender to make the LIBOR Rate Loan then being requested
                  as a Reference Rate Loan or to continue to maintain its
                  outstanding Reference Rate Loan then the subject of a Notice
                  of LIBOR Activity as a Reference Rate Loan or to convert its
                  LIBOR Rate Loans then outstanding that are so affected into
                  Reference Rate Loans at the end of the then current Interest
                  Period (or at such earlier time as prepayment is otherwise
                  required) in the manner contemplated by Section 4.6 but
                  without satisfying the advance notice requirements therein.

                  (f) Compensation. In addition to (but without duplication of)
         such amounts as are required to be paid by the Borrower pursuant to
         this Agreement, including, without limitation, Sections 4.1, 4.2, 4.3,
         4.4, 8.1 and 8.2, Borrower shall compensate each Lender, upon written
         request by such Lender (which request shall set forth in reasonable
         detail the basis for requesting such amounts), for all losses, costs,
         expenses and liabilities, including, without limitation, any loss, cost
         or expense incurred by reason of the liquidation or reemployment of
         deposits or other funds acquired by such Lender to fund or maintain
         such Lender's LIBOR Rate Loans to Borrower which such Lender may
         sustain (i) if for any reason a borrowing of any LIBOR Rate Loan does
         not occur on a date specified therefor in a Notice of LIBOR Activity,
         including an oral request for borrowing or conversion/continuation, or
         if a successive Interest Period does not commence after notice therefor
         is given pursuant to Section 4.6(b), (ii) if any voluntary or mandatory
         prepayment of any LIBOR Rate Loan occurs for any reason on a date which
         is not the last day of an Interest Period, (iii) as a consequence of
         any required conversion of a LIBOR Rate Loan to a Reference Rate Loan
         as a result of any of the events indicated in Section 4.6(d), or (iv)
         as a consequence of any other default by Borrower to repay any LIBOR
         Rate Loan when required by the terms of this Agreement.

                  (g) Manner of Funding of LIBOR Rate Loans. Each Lender shall
         be entitled to fund and maintain its funding of all or any part of any
         LIBOR Rate Loan requested by Borrower hereunder in any manner it sees
         fit, it being understood and agreed, however, that for the purposes of
         this Agreement, all determinations hereunder shall be made as if such
         Lender had actually funded and maintained each LIBOR Rate Loan during
         each Interest Period for such Loan through the purchase of deposits in
         the London interbank market having a maturity corresponding to such
         Interest Period and bearing an interest rate equal to the LIBOR Rate
         for such Interest Period.

                  (h) LIBOR Rate Loans After Default. Unless the Requisite
         Lenders shall otherwise agree in writing, after the occurrence and
         during the continuance of an Unmatured Event of Default or an Event of
         Default, Borrower may not elect to have a Loan be made or continued as,
         or converted to, a LIBOR Rate Loan after the expiration of any Interest
         Period then in effect for that Loan.

         SECTION 4.8 Interest Payment Dates. Accrued interest on each Reference
Rate Loan shall be payable in arrears on the first Business Day of each month,
and at maturity, commencing with the first of such dates to occur after the date
of the initial Loans. Accrued Interest on each LIBOR Rate Loan shall be payable
in arrears on each LIBOR Interest Payment Date applicable to such Loan and, in
any event, at maturity. After maturity (whether by acceleration or otherwise),
accrued interest on all Loans shall be due and payable on demand. Accrued
interest on Reimbursement Obligations shall be due and payable upon demand.

         SECTION 4.9 Setting of Rates. Interest rates hereunder shall be
calculated from time to time by Collateral Agent and each such calculation of an
interest rate shall be conclusive and binding on Borrower in the absence of
demonstrable error.

         SECTION 4.10 Computation of Interest. Interest on each Loan and
Reimbursement Obligation shall be computed for the actual number of days elapsed
on the basis of a year consisting of 360 days. In computing interest on any
Loan, the date of the making of the Loan or the first day of an Interest Period,
as the case may be, shall be included and the date of payment of the Loan or the
expiration date of an Interest Period, as the case may be, shall be excluded;
provided, however, that if a Loan is repaid on the same day on which it is made,
one day's interest shall in any event be paid on that Loan. The interest rate
applicable to each Reference Rate Loan and Reimbursement Obligation shall change
simultaneously with each change in the Reference Rate.

         SECTION 5 FEES.

         SECTION 5.1 Revolving Loan Non-Use Fee. Borrower shall pay to Lenders,
on a monthly basis, a non-use fee for the period from and including the date
hereof to but excluding the Revolving Loan Termination Date (or such earlier
date on which the Revolving Loan Commitment shall be terminated pursuant to
Section 2.5 or 13.2 hereof) of one-half of one percent (0.50%) per annum on the
excess of (i) the daily average of the then applicable 


                                       43


<PAGE>   57


Revolving Loan Commitment for the month then ending over (ii) the daily average
of the aggregate principal amount of outstanding Revolving Loans for the month
then ending. Such nonuse fee shall be payable in arrears on the first day of
each month (commencing on December 1, 1996) and on the Revolving Loan
Termination Date (or such earlier date on which the Revolving Loan Commitment
shall terminate) for any period then ending for which such fee shall not have
been theretofore paid.

         SECTION 5.2 Working Capital Loan Non-Use Fee. Borrower shall pay to
Lenders, on a monthly basis, a non-use fee for the period from and including the
date hereof to but excluding the Working Capital Loan Termination Date (or such
earlier date on which the Working Capital Loan Commitment shall be terminated
pursuant to Section 2.6 or 13.2 hereof) of one-half of one percent (0.50%) per
annum on the excess of (i) the daily average of the then applicable Working
Capital Commitment for the month then ending over (ii) for the month then ending
(x) the daily average of the aggregate principal amount of outstanding Working
Capital Loans for the month then ending plus (y) the daily average of the
aggregate principal amount of the outstanding Reimbursement Obligations for the
month then ending plus (z) (without double counting) the daily average of the LC
Utilization (which shall be rebuttably presumed to equal at any time the excess
of the Cap Amount at such time over the then aggregate outstanding principal
amount of the Reimbursement Obligations) for the month then ending, unless
Lenders have actually received certification from the applicable Issuer to the
contrary. Such non-use fee shall be payable in arrears on the first day of each
month (commencing on December 1, 1996) and on the Working Capital Loan
Termination Date (or such earlier date on which the Working Capital Loan
Commitment shall terminate) for any period then ending for which such fee shall
not have been theretofore paid.

         SECTION 5.3 Capital Expenditure Loan Non-Use Fee. Borrower shall pay to
Lenders, on a monthly basis, a non-use fee for the period from and including the
date hereof to but excluding the Capital Expenditure Loan Termination Date (or
such earlier date on which the Capital Expenditure Loan Commitment shall be
terminated pursuant to Section 2.8 or 13.2 hereof) of one-half of one percent
(0.50%) per annum on the excess of (i) the daily average of the then applicable
Capital Expenditure Loan Commitment for the month then ending over (ii) the
daily average of the aggregate principal amount of outstanding Capital
Expenditure Loans for the month then ending. Such nonuse fee shall be payable in
arrears on the first day of each month (commencing on December 1, 1996) and on
the Capital Expenditure Loan Termination Date (or such earlier date on which the
Capital Expenditure Loan Commitment shall terminate) for any period then ending
for which such fee shall not have been theretofore paid.

         SECTION 5.4 Closing Fee. On the date of the initial Loan, Borrower
shall pay to FSFP and Union Bank the commitment and closing fees set forth in
that certain Fee Letter Agreement of even date herewith among Borrower, FSFP and
Union Bank (the "Fee Letter Agreement").

         SECTION 5.5 Computation of Fees. All fees shall be computed for the
actual number of days elapsed on the basis of a year consisting of 360 days.

<PAGE>   58


         SECTION 5.6 Letter of Credit Fees. Borrower shall pay to Lenders a fee
for the period from and including the first date on which any Permitted LC is
outstanding to but excluding the Working Capital Loan Termination Date (or such
earlier date on which all of the LC Guaranties shall no longer be of any force
or effect and the originals thereof are returned by the appropriate Issuer to
Lenders and the applicable Issuer shall have acknowledged in writing that
Lenders shall have no further obligations thereunder) of two and three-quarters
of one percent (2.75%) per annum on the daily average of the aggregate Stated
Amounts of outstanding Permitted LCs (the "LC Utilization"). Such fees shall be
payable in arrears on the first day of each month (commencing on December 1,
1996) and on the date on which all of the LC Guaranties shall no longer be of
any force or effect. The LC Utilization shall be rebuttably presumed to equal at
any time the excess of the Cap Amount at such time over the then aggregate
outstanding principal amount of Reimbursement Obligations, unless Lenders have
actually received certification from the applicable Issuer to the contrary. All
LC Reimbursement Agreements shall require the applicable Issuer to provide
certification of the daily LC Utilization, but in the event such Issuer fails to
comply with such requirement, the preceding sentence shall apply.

         SECTION 6 ACCOUNT AGREEMENTS; ACCOUNTS; LIST OF ACCOUNTS AND ACCOUNT
                   STATEMENTS.

         SECTION 6.1 Account Agreements. Prior to the date of the initial Loan,
Borrower, its Subsidiaries, Agent Bank and such other Persons as are designated
by Collateral Agent shall enter into a Bank Agency Agreement (herein, as the
same may be amended, restated, modified or supplemented from time to time,
called the "Bank Agency Agreement"). Pursuant to the Collateral Documents,
including the Bank Agency Agreement, Borrower and its Subsidiaries shall grant
to Collateral Agent a continuing first priority lien upon, and security interest
in, the Master Account and the Operating Account, each described below
(collectively, the "Accounts"), all funds, items, instruments, investments,
securities and other things of value at any time paid, deposited, credited to or
held in the Lockbox or the Accounts (whether for collection, provisionally or
otherwise), and all other Property of Borrower and its Subsidiaries from time to
time in the possession or under the control of, or in transit to any Lender
Party or any agent, bailee or custodian therefor, and all proceeds of all of the
foregoing. The Bank Agency Agreement shall specify that throughout the term of
this Agreement, Agent Bank, to the extent any such Person is a party to the Bank
Agency Agreement, (i) shall be pledgee-in- possession (for the benefit of
Collateral Agent) of the Accounts described therein, all Cash Instruments of
Borrower and its Subsidiaries held by Agent Bank, and all such funds, items,
instruments, investments, securities, other things of value, Property and
proceeds, (ii) shall take such action as shall be specified in written notice
from Collateral Agent to enable Collateral Agent or Lenders to exercise their
rights with respect to such lien and security interest, (iii) shall be entitled
to exercise all and any rights which any Lender Party may have under this
Agreement and the Related Documents or applicable law with respect to the
Accounts described therein and such other Property and (iv) shall provide
Collateral Agent with copies of all statements relating to the Accounts provided
by Agent Bank to Borrower. Notwithstanding any provision of this Section 6.1,
Collateral Agent shall have no obligation to reconcile or verify, at any time or
for 


                                       45


<PAGE>   59


any purpose, any balance in any Account or any other account maintained by Agent
Bank as agent for Collateral Agent.

         SECTION 6.2 Accounts.

                  (a) Master Account and Lockbox. Collateral Agent shall
         maintain at Agent Bank the account identified as the "Master Account"
         in the Bank Agency Agreement (herein called the "Master Account") and
         Borrower shall maintain a lockbox with the Agent Bank (herein called
         the "Lockbox"). The Master Account and the Lockbox shall be under the
         sole dominion and control of Collateral Agent, and Borrower shall not
         have any right of withdrawal therefrom.

                  (b) Operating Account. Borrower and its Subsidiaries shall
         maintain the controlled disbursement operating accounts at Agent Bank
         described in the Bank Agency Agreement (such accounts being herein
         collectively called the "Operating Account").

                  (c) Other Accounts. Borrower shall not, and shall not permit
         any of its Subsidiaries to, maintain any operating account (other than
         the Operating Account), and agrees that it will not, and will not
         permit any of its Subsidiaries to, maintain any bank investment or
         other account of any kind whatsoever with any other brokerage house or
         financial institution; provided, however, that so long as no Event of
         Default shall have occurred and be continuing, Borrower may maintain
         the petty cash and payroll accounts listed on Schedule IV hereto at the
         financial institutions indicated thereon, provided that the aggregate
         amount of funds on deposit in each such petty cash account shall not
         exceed $5,000 and each such payroll account shall not at any time
         exceed the sum of all accrued payroll and payroll taxes then payable by
         Borrower on account of payroll obligations payable from such account;
         and provided, further, that (i) Borrower shall have irrevocably
         instructed the relevant financial institution, at the request of the
         Requisite Lenders, to provide Collateral Agent with information
         concerning such accounts, (ii) such financial institution shall
         acknowledge such instructions in writing for the benefit of Collateral
         Agent, and (iii) at any time when an Event of Default has occurred and
         is continuing Borrower shall, at the request of the Requisite Lenders,
         promptly cause each such financial institution to provide Collateral
         Agent with daily reports of the balance in each such account.

         SECTION 6.3 List of Accounts and Account Statements. All Accounts of
Borrower and its Subsidiaries and all payroll and petty cash accounts of
Borrower are described on Schedule IV. In the event Borrower or any of its
Subsidiaries opens any new accounts or closes any account in accordance with the
terms of this Agreement, Borrower shall deliver to Collateral Agent a revised
version of Schedule IV showing any changes thereto within three (3) Business
Days of any such change. Borrower shall instruct all banks listed on Schedule IV
to provide Collateral Agent with copies of all statements issued by such banks
with respect to the accounts described on Schedule IV.

         SECTION 7 PROCEEDS OF COLLATERAL; APPLICATION OF FUNDS; DEEMED LOANS.

         SECTION 7.1 Proceeds of Collateral; Notices to Account Debtors;
Lockbox. Borrower shall, and shall cause each of its Subsidiaries to, direct all
Account Debtors to pay all Accounts Receivable and other proceeds of Collateral
directly to the Lockbox for application to the Master Account. In addition,
Borrower shall take all such actions necessary or appropriate to ensure that at
all times on and after the date hereof all proceeds of Collateral (including,
without limitation, all Cash Instruments) are sent directly to the Lockbox. If,
notwithstanding the actions provided for in the preceding sentences of this
Section 7.1, Borrower or any of its Subsidiaries shall receive, or any financial
institution shall receive for the account of Borrower or any of its
Subsidiaries, any Cash Instruments, Borrower shall, or shall cause such
financial institution to, transmit in the form received, before the close of
business on the next succeeding Business Day, all such Cash Instruments
(properly endorsed, where required, so that all items delivered may be collected
by Agent Bank) to Agent Bank for deposit in the Master Account. Borrower shall
not, nor shall Borrower permit or cause any such financial institution to,
commingle any Cash Instrument so received except in the Master Account, and
Borrower shall hold separate and apart from all other Property, all such Cash
Instruments in express trust for the benefit of Collateral Agent until delivery
thereof is made to Agent Bank. Pursuant to, and subject to the terms and
conditions of, the Bank Agency Agreement, items deposited in the Lockbox shall
be credited to the Master Account.

         SECTION 7.2 Application of Funds Available for Operating Expenses. At
the opening of business on each Business Day, Agent Bank shall calculate the
amount of collected funds on deposit in the Master Account (herein, with respect
to the Master Account for any day, called the "Collected Balances" for such
day). Promptly upon such calculation (and in any event prior to 12:00 noon
Chicago time on such day), if no Event of Default shall have occurred and be
continuing and to the extent of Collected Balances available to do so, Agent
Bank shall transfer from the Master Account to the Operating Account such
amounts as shall permit all checks drawn on such Operating Account presented for
payment at Agent Bank as of the preceding Business Day and, provided Borrower
has given Collateral Agent notice of the amount of such wire transfers by 12:00
noon Chicago time no later than 1 Business Day and no sooner than 5 Business
Days prior to the date of such wire transfers, all wire transfers authorized on
such date for payments permitted hereunder, to be honored and leaving a zero
balance in the Operating Account after payment and transfer of such items from
the Operating Account.

         SECTION 7.3 Application of Funds Available for Loan Repayments.
Promptly after any disbursements pursuant to Section 7.2 are made, Agent Bank
promptly shall transfer to Collateral Agent in integral multiples of $5,000 the
remaining Collected Balances in excess of $450,000 but leaving a balance of at
least $300,000 but not more than $305,000 in the Master Account. Any amounts
received by Collateral Agent pursuant to this Section 7.3 shall be applied to
the outstanding obligations of Borrower in the following order of priority:
first, to accrued and unpaid interest on the Reimbursement Obligations; second,
to accrued and unpaid interest then 


                                       47


<PAGE>   61


due and payable on the Working Capital Loans; third, to accrued and unpaid
interest then due and payable on the Capital Expenditure Loans; fourth, to
accrued and unpaid interest then due and payable on the Revolving Loans; fifth,
to accrued and unpaid interest then due and payable on the Term Loans, sixth to
the unpaid principal amount of the Reimbursement Obligations; seventh, to the
unpaid principal amount of the Working Capital Loans then due and payable;
eighth, to the unpaid principal amount of the Revolving Loans then due and
payable; ninth, to any fees hereunder then due and payable, in such order as the
Requisite Lenders may elect; tenth, to the unpaid principal amount of the
Working Capital Loans not otherwise due and payable at such time (provided,
however, that prior to the termination of the Working Capital Commitment, the
unpaid principal amount of the Working Capital Loans shall never be less than
$1,000); eleventh, to the unpaid principal amount of the Revolving Loans not
otherwise due and payable at such time (provided, however, that prior to the
termination of the Revolving Loan Commitment, the unpaid principal amount of the
Revolving Loans shall never be less than $1,000); twelfth, to the payment of any
other Liabilities then due and payable to Lender; and thirteenth, any remainder
shall be retained in the Master Account and applied (a) first to the unpaid
principal amount of the Capital Expenditure Loans as and when due and payable
and last to the unpaid principal amount of the Term Loans as and when due and
payable. Notwithstanding the foregoing provisions of this Section 7.3 to the
contrary, any amounts received by Collateral Agent representing Asset Sale
Proceeds in respect of any Financed Equipment or insurance proceeds in respect
of any Financed Equipment shall be applied first to the unpaid principal amount
of the Capital Expenditure Loans, whether or not then due and payable.

         SECTION 7.4 Application Upon an Event of Default. If an Event of
Default shall have occurred and be continuing, and notwithstanding the foregoing
Section 7.3, at the request of Collateral Agent, Agent Bank from time to time
shall transfer all Collected Balances in the Master Account to Collateral Agent
for application to the Liabilities in such order as the Requisite Lenders, in
their sole discretion, shall elect. Agent Bank and Collateral Agent each shall
be entitled to rely on a written statement of the Requisite Lenders to the
effect that an Event of Default has occurred and is continuing.

         SECTION 7.5 Deemed Loans.

                  (a) Notwithstanding any provision contained herein to the
         contrary, if at any time or from time to time the balance in the Master
         Account is less than $10,000, Borrower shall, if the Requisite Lenders
         so elect, be deemed to have given the notice required by Section 2.3
         (and to have made all of the representations set forth in a Borrowing
         Certificate) of a proposed borrowing equal to the lesser of (i) the
         amount (which shall be $5,000 or an integral multiple thereof)
         necessary to increase such balance to at least $300,000, but not more
         than $305,000 and (ii) the remaining availability under the
         Commitments, and, in the event of such election, each Lender shall lend
         to Borrower its Pro Rata Share of such amount, the proceeds of which
         shall be deposited by such Lender in the Master Account. Such Loan
         shall be a Revolving Loan bearing interest at the rate described in
         Section 4.1(a) to the extent of unused availability of the Revolving
         Loan Commitment and, if the availability under the Revolving Loan
         Commitment is not 


                                       48


<PAGE>   62


         sufficient to make such Loan in its full principal amount, it shall be,
         to the extent of such insufficiency, a Working Capital Loan bearing
         interest at the rate described in Section 4.2(a) to the extent of
         availability of the Working Capital Commitment and, if the availability
         under the Working Capital Commitment is not sufficient to make such
         Loan in its full principal amount, it shall be, to the extent of such
         insufficiency, a Capital Expenditure Loan bearing interest at the rate
         described in Section 4.4(a) to the extent of availability of the
         Capital Expenditure Loan Commitment.

                  (b) Notwithstanding any provision contained herein to the
         contrary, and in addition to, and not in limitation of, any of the
         other rights or remedies of Lender Parties set forth herein, including,
         without limitation, pursuant to Section 7.4, at the sole option of the
         Requisite Lenders, in order to facilitate timely payment hereunder of
         all Liabilities in respect of (i) payments of principal and interest
         due on any Loans or Reimbursement Obligations, (ii) payments of cash,
         fees and expenses due and payable by Borrower to any Lender Party or
         under any of the Related Documents and (iii) payments by any Lender
         Party of any amount due and payable under the Bank Agency Agreement or
         any other agreement entered into by Collateral Agent and Agent Bank in
         connection with this Agreement (including, without limitation, any
         amount resulting from the return, dishonor or other non-payment of
         items deposited with Agent Bank by or on behalf of Borrower), then,
         whether or not there is availability under any Commitment, Borrower
         shall be deemed automatically to have made a request for, and upon such
         payment Lenders shall be deemed to have made, a Revolving Loan, a
         Working Capital Loan or a Capital Expenditure Loan (or any combination
         thereof, as determined by the Requisite Lenders in their sole and
         absolute discretion) in the full amount of such payment. Collateral
         Agent shall use its best efforts to give reasonable prior notice to
         Borrower of the making of such Loan; provided, however, that the
         failure to give such notice shall not affect the obligations of
         Borrower with respect to such Loan nor give rise to or result in any
         liability of any Lender Party. Borrower acknowledges that such Loan may
         cause Borrower to have exceeded a Commitment, in which event Borrower
         shall be obligated to immediately make a prepayment pursuant to Section
         2.9(e).

         SECTION 8 INCREASED COSTS AND OTHER SPECIAL PROVISIONS.

         SECTION 8.1 Increased Costs. If, after the date hereof, the adoption of
any applicable law, rule or regulation generally applicable to a financial
institution in the business of making and holding commercial loans, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority or agency charged with the interpretation or
administration thereof, or compliance by any Lender Party with any request or
directive (whether or not having the force of law) of any such authority or
agency, shall subject any Lender Party to any tax, duty or other charge or
capital adequacy requirement with respect to, or shall otherwise increase the
effective cost of, the Loans, the Reimbursement

Obligations, the LC Guaranties or any Lender's obligation to make, issue or
maintain the Loans, the Reimbursement Obligations or the LC Guaranties, or shall
change the basis of taxation of payments to any Lender Party of the principal of
or interest on the Loans, the Reimbursement Obligations or any other amounts due
under this Agreement in respect of the Loans, the Reimbursement Obligations or
the LC Guaranties, or any Lender's obligation to make, issue or maintain the

on any Lender Party any other condition affecting the Loans, the Reimbursement
Obligations or the LC Guaranties or any Lender's obligation to make the Loans or
the Reimbursement Obligations or maintain the LC Guaranties, and the result of
any of the foregoing is to increase the cost to any Lender of making, issuing or
maintaining the Loans, or to reduce the amount of any rate of return or any sum

with respect thereto, then upon written notice of such occurrence to Borrower by
such Lender (which notice shall contain a statement setting forth a description
of such occurrence), Borrower shall pay to such Lender such additional amount or
amounts as will compensate such Lender for such increased cost or such reduction
from the date of receipt of such notice (but not before). In such event,
Borrower shall have 90 days after the date of such notice to replace the Lender
giving such notice with a Lender not subject to the increased costs, and any
such replacement shall not give rise to any Prepayment Premium owing to the
replaced Lender.

receives a notice (whether written or oral) of borrowing or repayment pursuant
to this Agreement and Borrower fails to borrow or repay strictly in accordance
therewith, then, upon demand by any Lender (which demand shall be accompanied by
a statement setting forth the basis for the calculations of the amount being
claimed) Borrower will indemnify such Lender against any net loss or expense
which such Lender may sustain or incur (including, without limitation, any net
loss or expense incurred by reason of the liquidation or reemployment of funds
acquired by such Lender to fund or maintain Loans), as reasonably determined by
such Lender, as a result of any failure of Borrower to borrow or repay any Loan
on a date specified therefor in a notice (whether written or oral) of borrowing
or repayment pursuant to this Agreement. For this purpose, all notices to
Collateral Agent pursuant to this Agreement shall be deemed to be irrevocable.

         SECTION 8.3 Conclusiveness of Statements; Survival of Provisions. In
making the determinations contemplated by this Section 8, each Lender Party may
make such reasonable estimates, assumptions, allocations and the like such
Lender Party in good faith determines to be appropriate; and, subject to the
foregoing clause, determinations and statements of each Lender Party pursuant to
this Section 8 shall be conclusive absent demonstrable error. The provisions of
this Section 8 shall survive termination of this Agreement.

         SECTION 8.4 Discretion of Lenders as to Manner of Funding .
Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of the
Loans in any manner it sees fit.

         December 31, 1997 with respect to Borrower's leased premises in Yorba
         Linda, California);

                  (c) execute and deliver from time to time within ten (10) days
         after the purchase, acquisition or renewal by Borrower or any of its
         Subsidiaries of any real property or leasehold interest in real
         property or of property subject to a titling statute or of any other

                  (d) execute and deliver to Collateral Agent, in form and

         (including, without limitation, acknowledgements by other contract
         parties) as may be necessary to grant a Lien on such Person's rights
         and interests under such contract and each such property, whether under
         construction or otherwise, to Collateral Agent; and


                                       53


<PAGE>   67


                  (e) execute and deliver to Collateral Agent, in form and
         substance satisfactory to the Requisite Lenders and in such number of
         counterparts as the Requisite Lenders may require, assignments of such
         Person's rights under each lease to which such Person is a party as
         landlord or sublandlord, promptly upon entering into such lease, to
         Collateral Agent.

         SECTION 9.7 Asset Sales and Equity Sales. The parties hereto intend
that all Property of Borrower and each of its Subsidiaries shall be subjected to
Liens in favor of Collateral Agent to secure the Liabilities. Accordingly,
Borrower shall not consummate, or permit any of its Subsidiaries to consummate,
any Asset Sales or Equity Sales not permitted under Section 11.22 without the
prior written consent of the Requisite Lenders, which consent may be given or
withheld in the sole and absolute discretion of the Requisite Lenders, and may
be based, without limitation, on any Lender Party's evaluation of the adequacy
of the consideration proposed to be received by Borrower or any of its
Subsidiaries in connection with any such disposition and the effect of such
disposition on Borrower's and such Subsidiary's net worth, and on Net Income,
Net Cash Generated, interest coverage ratios or other financial criteria.
Without limiting the generality of the foregoing, and without limiting the right
of the Requisite Lenders to require any other application of proceeds or
modification of this Agreement and the Related Documents, or any greater payment
of Loans, Reimbursement Obligations or reduction of Commitments, it is the
present anticipation of the parties that all Asset Sale Proceeds and Equity Sale
Proceeds will be applied as a mandatory prepayment of the Loans pursuant to
Section 2.9 and that the Commitments shall be automatically and permanently
reduced in the amount of such prepayments to the extent provided in Section 2.5,
Section 2.6, Section 2.7 and Section 2.8.

         SECTION 10 REPRESENTATIONS AND WARRANTIES.

         To induce Collateral Agent, Administrative Agent and Lenders to enter
into this Agreement and to induce Lenders to make Loans and other financial
accommodations hereunder, Borrower represents and warrants to Collateral Agent,
Administrative Agent and Lenders that:

         SECTION 10.1 Due Organization, Authorization. Borrower and each of its
Subsidiaries is a corporation duly existing and in good standing under the laws
of the jurisdiction of its incorporation and is duly qualified and in good
standing in each jurisdiction where, because of the nature of its activities or
properties, such qualification is required or the failure so to qualify could
have a Material Adverse Effect (which jurisdictions shall include, without
limitation, those jurisdictions listed in Part 1 of Schedule IX). The execution,
delivery and performance by Borrower, each of its Subsidiaries and Parent of
this Agreement and the Related Documents to which they respectively are parties,
and the consummation of the Related Transactions, are within their respective
corporate powers, have been duly authorized by all necessary corporate action
(including, without limitation, shareholder approval), have received all
necessary governmental and other consents and approvals (if any shall be
required), and do not and will not contravene or conflict with, or create a Lien
or right of termination or acceleration under, any Requirement of Law or
Contractual Obligation binding upon any of it. This Agreement and each of the
Related Documents to which Borrower, any of its Subsidiaries 


                                       54


<PAGE>   68


or Parent is a party are (or when executed and delivered will be) the legal,
valid, and binding obligations of such Person enforceable against it in
accordance with their respective terms, except as limited by general principles
of equity and applicable bankruptcy, reorganization, insolvency or similar laws
affecting the enforcement of creditors' rights.

         SECTION 10.2 Certain Agreements. Borrower has furnished or caused to be
furnished to Lenders true, correct and complete copies of each of the Related
Documents, the Acquisition Instruments, the Subordinated Loan Instruments, the
Equity Instruments, the Management Agreement and the Employment Agreements
(including all schedules and written disclosures in connection therewith). All
representations and warranties of Borrower set forth in this Agreement and the
Related Documents and all representations and warranties of Borrower and to
Borrower's best knowledge after due inquiry, all representations and warranties
of the other parties thereto, set forth in the Acquisition Instruments, the
Subordinated Loan Instruments, the Equity Instruments, the Management Agreement
and the Employment Agreements are true and correct in all material respects
without any waiver or modification thereof and no default of any party exists
thereunder.

         SECTION 10.3 Financial Information; Financial Condition. All balance
sheets, all statements of net assets, all statements of operations, of
shareholders' equity and of changes in financial position, and other financial
data (other than projections) which have been or shall hereafter be furnished to
any Lender Party for the purposes of or in connection with this Agreement, the
Related Documents or the Related Transactions (including the financial
information referred to below, except for the projections referred to in clause
(d) below) have been and will be prepared in accordance with GAAP consistently
applied throughout the periods involved and do and will present fairly the
financial condition of the entities involved as of the dates thereof and the
results of their operations for the periods covered thereby except that (i) in
the case of the Audited Financials (as defined below), the foregoing
representation is made (A) subject to adjustments and inconsistencies which may
arise in connection with the preparation of consolidated financial statements of
Seller and (B) except as otherwise stated in the reports that accompanied the
Audited Financials, (ii) the Unaudited Financials (as defined below) have been
prepared in accordance with Seller's usual historical practice for the
preparation of monthly financial statements and the foregoing representation is
subject to adjustments and inconsistencies arising therefrom and (iii) the
foregoing representation with respect to such financial data of Seller is made
by Borrower to its best knowledge after due inquiry. All projections (including,
without limitation, the projections described in clause (d) below) which have
been or shall be furnished to any Lender Party for purposes of or in connection
with this Agreement, the Related Documents or the Related Transactions have
represented and will represent at the time made management's best estimates of
future performance, based upon historical financial information and reasonable
assumptions of management. Such financial data include, without limitation, the
following financial statements and reports which have been furnished to Lenders
prior to the date hereof:

                  (a) the audited consolidated balance sheet of Seller as of
         December 31, 1995 and the statement of net assets of Steri-Oss as of
         December 31, 1995 and the eight month 


                                       55


<PAGE>   69


         period ended August 24, 1996 and the related combined statements of
         income and cash flows of Steri-Oss for the periods ending on such dates
         (the "Audited Financials");

                  (b) the unaudited statement of net assets of Steri-Oss and
         related combined statements of income and cash flows of Steri-Oss
         certified by the chief financial officer of B&L, for the month ending
         September 27, 1996 and for the month of October, 1996 (the "Unaudited
         Financials");

                  (c) pro forma consolidated balance sheet of Borrower and its
         Subsidiaries as of October 25, 1996 after giving effect to all Related
         Transactions;

                  (d) consolidated cash flow projections for Borrower and its
         Subsidiaries for the Fiscal Years 1997 through 2002, based on the
         historical financial statements and records of Steri-Oss, after giving
         effect to all Related Transactions; and

                  (e) projected consolidated balance sheets, and statements of
         earnings, shareholders' equity and changes in financial position for
         Borrower and its Subsidiaries for each month in Fiscal Year 1997 and
         each quarter in Fiscal Year 1998, based on the historical financial
         statements and records of Steri-Oss, after giving effect to all Related
         Transactions.

As of the Closing Date there has been no material adverse change since August
24, 1996 in the financial condition, operations, assets, business or prospects
of Steri-Oss or B&L, other than as a result of the Related Transactions, from
that reflected in the financial information referred to in clauses (a) through
(c). No notices or other communications have been given or received with respect
to the matters described in Section 4.23 of the Asset Purchase Agreement, except
such as have been delivered to Lenders by Borrower prior to the Closing Date.

         On the Closing Date and after giving effect to the Related
Transactions, (i) the assets of Borrower and each of its Subsidiaries, including
Intangible Assets, at a fair valuation, will exceed its liabilities, including
contingent liabilities, (ii) the capital of Borrower and each of its
Subsidiaries will not be unreasonably small to conduct its business and (iii)
neither Borrower nor any of its Subsidiaries has incurred debts, nor does it
intend to incur debts, beyond its ability to pay such debts as they mature. For
purposes of this Section 10.3, "debt" means any liability on a claim, "claim"
means a (x) right to payment, whether or not such right is reduced to judgment,
liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed,
undisputed, legal, equitable, secured or unsecured; or (y) right to an equitable
remedy for breach of performance if such breach gives rise to a payment, whether
or not such right to an equitable remedy is reduced to judgment, fixed,
contingent, matured, unmatured, disputed, undisputed, secured or unsecured and
"contingent liabilities" shall be computed as the amount of such liabilities
which, in light of all the facts and circumstances existing on the date hereof,
represents the maximum amount that reasonably can be expected to become absolute
and matured liabilities determined in good faith.


                                       56

         SECTION 10.4 Litigation and Contingent Obligations. As of the date of
the initial Loan, except as set forth (including estimates of the dollar amounts
involved) in Schedule V hereto and except for claims as to which the insurer has
admitted coverage in writing and which are fully covered by insurance, no
claims, litigation (including, without limitation, derivative actions and
litigation with respect to any Employee Benefit Plan), arbitration, governmental
investigation or proceeding or inquiry is pending or, to the best of Borrower's
knowledge after due inquiry, threatened against Borrower, any of its
Subsidiaries, Parent or Seller which could, if adversely determined, have a
Material Adverse Effect. As of the date of the initial Loan, other than any
liability incident to such claims, litigation or proceedings, neither Borrower
nor any of its Subsidiaries has any material Contingent Obligations not provided
for or referred to in the financial statements delivered under Section 10.3(a)
or (b) or in Schedule XII hereto.

         SECTION 10.5 Liens. At all times on and after the making of the initial
Loan, none of the assets of Borrower or any of its Subsidiaries will be subject
to any Lien, except for Permitted Liens which (except for Permitted Prior Liens)
are junior to the Lien of the Collateral Documents. Except as described in Part
1 of Schedule XII and except for Permitted Prior Liens, Collateral Agent will
obtain, as security for the Liabilities, (a) a legally valid and binding first
Lien on all real property and interests in real property described in the
Mortgages, and (b) a first perfected Lien on all other property described in the
Collateral Documents as being pledged, assigned or granted thereby. The legal
descriptions attached to the Mortgages, together with the descriptions of other
property described in the Collateral Documents, correctly describe all property
used in the business or operations of Borrower and its Subsidiaries in a manner
sufficient to create an enforceable Lien on or security interest in such
property.

         SECTION 10.6 Absence of Default. Neither Borrower nor any of its
Subsidiaries is in material default under any contract or contracts (a) to which
it is a party or by which it is bound, and (b)(i) pursuant to which Borrower
and/or such Subsidiary provides goods or services to a customer which
contributed more than $250,000 of gross revenue during the prior Fiscal Year of
Borrower or which is reasonably expected to contribute more than $250,000 of
gross revenue during the current Fiscal Year of Borrower, or (ii) pursuant to
which Borrower and/or such Subsidiary incurs Lease Obligations in excess of
$100,000 during any Fiscal Year, or (iii) which cannot be replaced without
material expense, delay or interruption of business (including, without
limitation, any Material Intellectual Property Right).

         SECTION 10.7 Employee Benefit Plans.

                  (a) Neither Borrower nor any member of its Controlled Group
         have incurred any liability with respect to any Pension Plan or
         Multiemployer Plan other than to pay premiums to the PBGC and make
         contributions to any such Pension Plan (provided that any such
         contributions and premiums which have been due have been paid).

                  (b) With respect to each Pension Plan, full and timely payment
         has been made of all amounts required under Code Section 412, Section
         302 of ERISA and under the terms of each such plan; no event or
         condition has occurred which has or could result in 


                                       57


<PAGE>   71


         the imposition of a lien or an accumulated funding deficiency (whether
         or not waived) under Code Section 412 or Section 302 of ERISA; Borrower
         and each member of its Controlled Group have fulfilled their
         obligations, if any, under the minimum funding standards of ERISA and
         the Code; and no security has been posted or is required to be posted
         under Section 401(a)(29) of the Code or Section 307 of ERISA.

         out of the following:

                           (i) any injury to person or damage to property, known
                  or unknown, reported or unreported, which results from the use

This Agreement and the Related Documents contain the entire agreement of the
parties hereto with respect to the matters covered hereby.

         SECTION 14.12 Confidentiality. Borrower agrees that FSFP may disclose
information relating to Borrower to the Master Lenders, the Master Agents and
the Surety Provider, which have agreed to use procedures substantially
comparable to those used by them in respect of non-public information as
supplied to them by or on behalf of FSFP to the extent that such information is
not and does not become publicly available and which FSFP indicates at the time
is to be treated confidentially; provided, however, that each of the Master
Lenders, the Master Agents and the Surety Provider, as the case may be, is
hereby authorized to deliver a copy of each or any financial statement of
Borrower or any other information relating to the Loans, or the Collateral,
which may be furnished to it hereunder or otherwise to (a) its legal counsel,
auditors and other professional advisors, (b) governmental or regulatory
authorities having jurisdiction over it, (c) independent financial rating
agencies (including, without limitation, the Rating Agencies), (d) any person
providing general liquidity or credit enhancement to the Master Lenders or the
Surety Provider, and (e) subject to obtaining a confidentiality agreement
containing the foregoing confidentiality restrictions, any Person to whom a
Master Lender or Surety Provider proposes to assign all or any part of its
interest or grant a participation in its interest, provided that the Surety
Provider shall have the right to give participations in its rights under the
Insurance and Indemnity Agreement and to enter into contracts of reinsurance
with respect to the Surety Policy without obtaining a confidentiality agreement
from such participant or reinsurers as the case may be; however, the Surety
Provider will advise such participant or reinsurers as the case may be of the
confidentiality provisions of the Master Credit Agreement. As used herein:
"Master Agents" shall mean Citicorp North America, Inc. ("CNAI"), Bank of New
York and any successor thereto or assignee thereof; "Master Lender" shall mean
any person becoming a "Lender" party to that certain Second Amended and Restated
Credit Agreement dated as of May 24, 1996 (as amended from time to time, the
"Master Credit Agreement") among First 


                                       90


<PAGE>   104


Source Financial, Inc., FSFP, Master Agents, such Lenders, Surety Provider, et
al; "Surety Provider" shall mean AMBAC Indemnity Corporation, in its capacity as
surety provider under the Master Credit Agreement, and any successor thereto;
"Surety Policy" shall mean the financial guaranty policy dated as of May 24,
1996 issued by the Surety Provider in favor of CNAI on behalf of the Master
Lenders; "Rating Agencies" shall mean Standard and Poor's Ratings Group, a
division of McGraw-Hill, Inc., and Moody's Investors Services, Inc.; and
"Insurance and Indemnity Agreement" means the insurance agreement among FSFP,
Surety Provider and the other parties thereto.

         Except as set forth above in this Section 14.12, each Lender and each
Agent will utilize reasonable good faith efforts to maintain as confidential any
information obtained from Borrower (to the extent each Lender and each Agent are
advised by Borrower that such information is confidential and other than
information which (i) at the time of disclosure or thereafter is generally
available to and known by the public (other than as a result of a disclosure
directly or indirectly by any Lender Party), (ii) is available to any Lender
Party on a non-confidential basis from a source other than Borrower, provided
that such source was not known by such Lender Party to be bound by a
confidentiality agreement with Borrower, (iii) is required to be disclosed
pursuant to any Requirement of Law or in connection with any litigation arising
out of or related to this Agreement or (iv) has been independently developed by
any Lender Party), provided that any Lender Party may disclose any such
information to any Eligible Assignee provided such Eligible Assignee agrees to
the terms of this paragraph or otherwise with the consent of Borrower.

         SECTION 15 ASSIGNMENT AND PARTICIPATION; AGENTS

         SECTION 15.1 Assignments and Participations in Loans and Notes.

         Each Lender may assign its rights and delegate its obligations under
this Agreement to any Eligible Assignee which is not a competitor or an
Affiliate of any competitor of Borrower; provided that (i) such Lender shall
first obtain the written consent of the Requisite Lenders, (ii) the aggregate
amount of the outstanding Commitment and Loans of the assigning Lender being
assigned pursuant to such assignment (determined as of the date of the
Assignment and Acceptance entered into with respect to such assignment by the
assigning Lender and the assignee, and accepted by Administrative Agent, in form
and substance satisfactory to Administrative Agent, the assigning Lender and the
assignee (the "Assignment and Acceptance")) shall in no event be less than
$5,000,000 of the assigning Lender's rights and obligations under this Agreement
and (iii) the parties to each such assignment shall execute and deliver to
Administrative Agent, for its acceptance and recording in the Register (as
hereinafter defined), an Assignment and Acceptance. In the case of an assignment
authorized under this Section 15.1, the assignee shall have, to the extent of
such assignment, the same rights, benefits and obligations as it would if it
were a Lender hereunder and the assigning Lender shall be relieved of its
obligations hereunder with respect to its Commitment to the extent of such
assignment. Borrower hereby acknowledges and agrees that any assignment will
give rise to a direct obligation of Borrower to the assignee and that the
assignee shall be considered to be a "Lender."


                                       91


<PAGE>   105


         Administrative Agent shall maintain at its address set forth on the
signature page hereto a copy of each Assignment and Acceptance delivered to and
accepted by it and books and records, including computer records, in which it
shall record the names and addresses of the Lenders and the Commitment of, and
principal amount of the Loans owing to, each Lender from time to time (the
"Register"). The entries in the Register shall constitute rebuttably presumptive
evidence, absent manifest error, of the accuracy of the information contained
therein, and Parent, Borrower, Borrower's Subsidiaries, Collateral Agent,
Administrative Agent and the Lenders may treat each Person the name of which is
recorded in the Register as a Lender hereunder for all purposes of this
Agreement. The Register shall be available for inspection by Collateral Agent,
any Lender or Borrower at any reasonable time and from time to time upon
reasonable prior notice.

         Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee, together with the Notes subject to such
assignment, Administrative Agent shall, if such Assignment and Acceptance has
been completed, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to Borrower. Within five (5) Business Days after Borrower's receipt of
such notice, Borrower, at its own expense, will execute and deliver to
Administrative Agent in exchange for the surrendered Notes, new Notes, to the
order of such assignee in amounts corresponding to the interest in the assigning
Lender's rights and obligations under this Agreement acquired by such assignee
pursuant to such Assignment and Acceptance and, if the assigning Lender has
retained an interest in such rights and obligations hereunder, new Notes to the
order of the assigning Lender in amounts corresponding to such interest retained
by it hereunder. Such Notes shall be in an aggregate principal amount equal to
the aggregate principal amount of such surrendered Notes, shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the forms of Exhibits E, F, G, and H, as applicable. Upon delivery
of such new Notes, the surrendered Notes shall be cancelled by Administrative
Agent and returned to Borrower.

         Each Lender may sell participations in all or any part of any Loans
made by it to any Eligible Assignee which is not a competitor or an Affiliate of
any competitor of Borrower; provided that (i) immediately after giving effect to
any participation, the aggregate amount of the outstanding Commitment and Loans
still held by the Lender granting the participation for its own account shall in
no event be less than $5,000,000 and (ii) all amounts payable by Borrower
hereunder shall be determined as if that Lender had not sold such participation
and the holder of any such participation shall not be entitled to require such
Lender to take or omit to take any action hereunder except action directly
affecting (a) any reduction in the principal amount, interest rate or fees
payable with respect to any Loan in which such holder participates; (b) any
extension of the final scheduled maturity date of the principal amount of the
Loans in which such holder participates; and (c) any release of any Collateral
(other than in accordance with the terms of this Agreement or the Related
Documents).

     Except as otherwise provided in this subsection 15.1 no Lender shall, as
between Borrower and that Lender, be relieved of any of its obligations
hereunder as a result of any sale, 


                                       92


<PAGE>   106


assignment, transfer or negotiation of, or granting of participation in, all or
any part of the Loans, the Notes or other Liabilities owed to such Lender. Each
Lender may furnish any information concerning Borrower and its Subsidiaries in
the possession of that Lender from time to time to assignees and participants
(including prospective assignees and participants).

         SECTION 15.2 Appointment of Agents.

     FSFP is hereby appointed Collateral Agent hereunder to act on behalf of all
Lenders as collateral agent under this Agreement and the Related Documents.
Union Bank is hereby appointed Administrative Agent hereunder to act on behalf
of all Lenders as administrative agent under this Agreement and the Related
Documents. The provisions of this subsection 15.2 are solely for the benefit of
Agents and Lenders and no Person shall have any rights as a third party
beneficiary of any of the provisions hereof. In performing their respective
functions and duties under this Agreement and the Related Documents, each Agent
shall act solely as an agent of Lenders and does not assume and shall not be
deemed to have assumed any obligation towards or relationship of agency or trust
with or for Borrower or any of its Subsidiaries. The agency hereby created shall
in no way impair or affect any of the rights and powers of, or impose any duties
or obligations upon, either Agent in its individual capacity as a Lender
hereunder. Each Agent shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not performing the
duties and functions delegated to it hereunder. Either Agent may resign at any
time by giving thirty (30) days prior written notice thereof to each Lender and
Borrower. Upon any such resignation, the Requisite Lenders shall have the right,
upon five days notice to Borrower, to appoint a successor Agent who is a Lender
or an Eligible Assignee. Upon acceptance of appointment, the successor Agent
shall succeed to and become vested with all rights, powers, privileges and
duties of the retiring Agent under this Agreement and the Related Documents, and
the retiring Agent shall be discharged from its duties and obligations under
this Agreement and the Related Documents.

         If either Agent shall request instructions from the Requisite Lenders
with respect to any act or action (including failure to act) in connection with
this Agreement or any Related Document, then such Agent shall be entitled to
refrain from such act or taking such action unless and until such Agent shall
have received instructions from Requisite Lenders; and such Agent shall not
incur liability to any Person by reason of so refraining. Each Agent shall be
fully justified in failing or refusing to take any action hereunder or under any
Related Document (a) if such action would, in the opinion of such Agent be
contrary to law or the terms of this Agreement or any Related Document or (b) if
such Agent shall not first be indemnified to its satisfaction by Lenders against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action. Without limiting the foregoing, no
Lender shall have any right of action whatsoever against either Agent as a
result of such Agent acting or refraining from acting hereunder or under any
Related Document in accordance with the instructions of the Requisite Lenders.

         SECTION 15.3 Investigation. Each Lender shall make its own independent
investigation of the financial condition and affairs of the Parent and its
Subsidiaries (including 


                                       93


<PAGE>   107


Borrower) in connection with the making and the continuance of the Loans
hereunder, and shall make its own appraisal of the creditworthiness of the
Parent and its Subsidiaries (including Borrower), and neither Agent shall have
no duty or responsibility, either initially or on a continuing basis, to provide
any Lender with any credit or other information with respect thereto, whether
coming into its possession before the date of this Agreement or at any time or
times thereafter, or to determine or verify the existence, eligibility or value
of any of the Collateral, or the correctness of any notice of borrowing. In
addition, neither Agent nor its counsel shall be responsible to the Lenders for
the enforceability or validity of this Agreement or any of the Related Documents
or for the existence, creation, attachment, perfection or priority of any
Security Interest in the Collateral. Neither Agent shall be responsible to any
Lender for any recitals, statements, representations or warranties contained in
this Agreement or for the execution, effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Agreement or any of the
Related Documents or any of the transactions contemplated hereby or thereby, or
for the financial condition of the Parent or any of its Subsidiaries (including
Borrower). Each Agent shall be entitled to rely upon any written notices,
statements, certificates, orders or other documents or any telephone message
believed by it in good faith to be genuine and correct and to have been signed,
sent or made by the proper Person, and with respect to all matters pertaining to
this Agreement or any of the Related Documents and its duties hereunder or
thereunder, upon advice of counsel selected by it.

         SECTION 15.4 Indemnification. To the extent that either Agent is not
reimbursed and indemnified by Parent, Borrower or any of its Subsidiaries, the
Lenders will reimburse and indemnify each Agent for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses, advances or disbursements of any kind or nature whatsoever
which may be imposed on, incurred by or asserted against such Agent in any way
relating to or arising out of this Agreement or any of the Related Documents or
any action taken or omitted by Agent under this Agreement or the Related
Documents, in proportion to each Lender's Pro Rata Share, including, without
limitation, Agent Advances made pursuant to Section 15.6. The obligations of the
Lenders under this Section 15.4 shall survive the payment in full of the Loans
and the termination of this Agreement.

         SECTION 15.5 Set Off and Sharing of Payments. In addition to any rights
now or hereafter granted under applicable law and not by way of limitation of
any such rights, upon the acceleration of the Liabilities, each Lender and each
holder of any Note is hereby authorized by Borrower at any time or from time to
time, without notice to Borrower or to any other Person, any such notice being
hereby expressly waived, to set off and to appropriate and to apply any and all
balances held by it at any of its offices for the account of Borrower or any of
its Subsidiaries (regardless of whether such balances are then due to Borrower
or its Subsidiaries) and any other property at any time held or owing by that
Lender or that holder to or for the credit or for the account of Borrower
against and on account of any of the Liabilities which are not paid when due;
provided that no Lender shall exercise any such right without giving prior
written notice to Collateral Agent. Any Lender or holder of any Note having a
right to set off shall, to the extent the amount of any such set off exceeds its
Pro Rata Share of the Liabilities, purchase for cash (and the other Lenders or
holders shall sell) participations in each such other Lender's or holder's 


                                       94


<PAGE>   108


Pro Rata Share of the Liabilities as would be necessary to cause such Lender to
share such excess with each other Lender or holder in accordance with their
respective Pro Rata Shares. Borrower agrees, to the fullest extent permitted by
law, that (a) any Lender or holder may exercise its right to set off with
respect to amounts in excess of its Pro Rata Share of the Liabilities and may
sell participations in such excess to other Lenders and holders and (b) any
Lender or holder so purchasing a participation in the Loans made or other
Liabilities held by other Lenders or holders may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender or holder were a direct holder of Loans and other
Liabilities in the amount of such participation.

         SECTION 15.6 Disbursement of Funds. Collateral Agent may, on behalf of
Lenders, make such disbursements and advances ("Agent Advances") pursuant to
this Agreement and the Related Documents which the Requisite Lenders, in their
sole discretion, deem necessary or desirable to preserve or protect the
Collateral, or any portion thereof, in order to enhance the likelihood of, or
maximize the amount of, repayment by Borrower, or any guarantor or other Person,
of the Loans and other Liabilities or to pay any other amount chargeable to
Borrower pursuant to the terms of this Agreement, including, without limitation,
costs, fees and expenses as described in Section 14.4. Agent Advances shall be
repayable on demand and be secured by the Collateral. Agent Advances shall
constitute Revolving Loans and shall otherwise constitute Liabilities to pay
principal hereunder and shall bear interest at the rate applicable to the
Revolving Loans. Collateral Agent shall notify each Lender in writing of each
such Agent Advance, which notice shall include a description of the purpose of
such Agent Advance. Without limitation of any of its obligations under this
Agreement, each Lender agrees that it shall make available to Collateral Agent,
upon Collateral Agent's demand, in immediately available funds, an amount equal
to such Lender's Pro Rata Share of each such Agent Advance. If such funds are
not made available to Collateral Agent by such Lender within one (1) Business
Day after Collateral Agent's demand therefor, Collateral Agent will be entitled
to recover any such amount from such Lender together with interest thereon at
the Federal Funds Rate for each day during the period commencing on the date of
such demand and ending on the date such amount is received. Each Lender shall
reimburse Collateral Agent on demand for all Loans disbursed on its behalf by
Collateral Agent, or if Collateral Agent so requests, each Lender will remit to
Collateral Agent its Pro Rata Share of any Loan before Collateral Agent
disburses same to Borrower. If any Lender fails to pay the amount of its Pro
Rata Share forthwith upon Collateral Agent's demand, Collateral Agent shall
promptly notify Borrower, and Borrower shall immediately repay such amount to
Collateral Agent. Nothing in this Section 15.6 shall be deemed to require
Collateral Agent to advance funds on behalf of any Lender or to relieve any
Lender from its obligation to fulfill its Commitments hereunder or to prejudice
any rights that Borrower may have against any Lender as a result of any default
by such Lender hereunder.

                                 (Section 2.1.3)

                                   LC GUARANTY


         THIS GUARANTY, dated as of ______________, 19__, is from FIRST SOURCE
FINANCIAL LLP, an Illinois registered limited liability partnership
("Guarantor"), to [APPLICABLE ISSUER], a _________________ ("Bank").

                                R E C I T A L S:

         WHEREAS, _________________________________. ("Obligor"), and Bank have
entered into that certain LC Reimbursement Agreement, dated _________, 19__ (the
"Letter of Credit Agreement"); and

         WHEREAS, pursuant to the Letter of Credit Agreement, Bank is issuing
the Letters of Credit described in Schedule I hereto, as such schedule may be
amended with the prior written consent of Guarantor from time to time to provide
for additional Letters of Credit, in the stated amounts (such amount with
respect to any such Letter of Credit being herein called its "Stated Amount"),
and for the benefit of such persons, as are specified in such Schedule I (the
foregoing Letters of Credit being herein referred to as the "Credits"); and

         WHEREAS, it is a condition precedent to the issuance of the Credits
that Guarantor provide this Guaranty to Bank; and

         WHEREAS, Guarantor, for good and sufficient consideration, the receipt
of which is hereby acknowledged, is willing to execute and deliver this
Guaranty;

         NOW, THEREFORE, Guarantor hereby agrees for the benefit of Bank as
follows:

         1. Guaranty. For value received, and to induce Bank to issue the
Credits, Guarantor hereby unconditionally and irrevocably guarantees, as primary
obligor and as surety, whether at stated maturity, by acceleration or otherwise,
the full and punctual payment when due of all reimbursement and other
obligations of Obligor to Bank arising from or related to the Credits
(collectively, the "Obligations"), and agrees to pay any reasonable expenses
(including reasonable counsel fees and expenses) incurred by Bank in enforcing
any right under this Guaranty. The right of recovery against Guarantor under
this Guaranty is, however, limited to the Cap Amount (as hereinafter defined)
plus accrued interest on such amount and plus all expenses of enforcing this
Guaranty. The Cap Amount as of ______________, 199__ (the "Closing Date") shall
be $___________ (the "Cap Amount"); provided, however, that the then current Cap
Amount shall be automatically reduced by the Stated Amount of each Credit when
(i) such Credit terminates or expires, (ii) such Credit has been surrendered by
the beneficiary thereof to Bank, and (iii) subject to Section 2(a), if such
Credit has been drawn upon, Bank has been reimbursed in full for its
disbursement thereunder, and provided further that interest
accruing more than thirty (30) 


<PAGE>   127


days after the date of Bank's honoring of any demand under a Credit shall not be
reimbursed if Bank fails to give the written notice required in Section 2(a)
hereof within thirty (30) days after Bank's honoring of the related demand.

         2.       Guaranty Absolute.

                  (a) This is a guarantee of payment and not merely of
         collection. Guarantor hereby covenants and agrees that in case Obligor
         shall fail duly and punctually to pay the Obligations on the date on
         which such payment is due, Guarantor will, within five (5) days of the
         actual receipt of written notice from Bank to such effect, and of the
         amount which Obligor has failed to pay, pay such amount, subject to the
         penultimate sentence of Section 1 hereof. The liability of Guarantor
         under this Guaranty shall be absolute and unconditional and shall not
         be discharged except by valid, final and irrevocable payment as herein
         provided, irrespective of: (i) any law, regulation, or order, or
         interpretation thereof, now or hereinafter in effect in any
         jurisdiction affecting or purporting to affect any of the terms or
         rights of Bank with respect to the Obligations or with respect to this
         Guaranty; (ii) any lack of validity or enforceability of the Letter of
         Credit Agreement; (iii) any exchange, release or non-perfection of any
         collateral, or any release or amendment or waiver of or consent to
         departure from any other guaranty, for all or any of the Obligations;
         or (iv) any other circumstances which might otherwise constitute a
         defense available to, or a discharge of, Obligor in respect of any of
         the Obligations of Guarantor in respect of any obligations under this
         Guaranty. This Guaranty shall continue to be effective or be
         reinstated, as the case may be, if at any time such payment of any of
         the Obligations is rescinded or must otherwise be returned by Bank upon
         the insolvency, bankruptcy or reorganization of Obligor or otherwise,
         all as though such payment had not been made.

                  (b) Except for any liability under the last sentence of
         subparagraph 2(a), the Guaranty shall continue in effect with respect
         to the Credit until 4:59 p.m., Chicago time, on the date following
         seven (7) days after the then current expiry date of such Credit;
         provided, however, that this Guaranty shall continue in effect until no
         Obligations are owing under the Credits and the Letter of Credit
         Agreement.

         3. Waiver. Guarantor hereby unconditionally waives, except as expressly
provided in this Guaranty, in the Letter of Credit Agreement or in any Credit:
(a) promptness, diligence, notice of acceptance and any other notice with
respect to any of the Obligations and this Guaranty; (b) presentment for
payment, notice of nonpayment, demand, protest, notice of protest and notice of
dishonor or default to any party including Guarantor, and any requirement that
Bank protect, secure, perfect or insure any security interest or lien of any
property subject thereto or exhaust any right or take any action against Obligor
or any other person or entity or any collateral; (c) all other notices to which
Guarantor may be entitled but which may legally be waived; and (d) to the
maximum extent provided by law, all rights under any state or federal statute
dealing with or affecting the rights of creditors.

         4. No Waivers; Remedies. No failure or delay on the part of Bank in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or 


<PAGE>   128


partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof, or the exercise of any other right, power or
privilege. Failure by Bank to insist upon strict performance hereof shall not
constitute a relinquishment of its right to demand strict performance at another
time. Receipt by Bank of any payment by any person of the Obligations, with
knowledge of a default with respect to any of the Obligations or of a breach of
this Guaranty, or both, shall not be construed as a waiver of the default or
breach. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

         5. Representations and Warranties. Guarantor hereby represents and
warrants as follows:

                  (a) Guarantor is duly organized and validly existing and has
         the power and authority to execute and deliver, and to perform its
         obligations under, this Guaranty.

                  (b) The execution and delivery of this Guaranty by Guarantor
         and the performance of its obligations hereunder have been and remain
         duly authorized by all necessary action and do not contravene any
         provision of its membership agreement or any law, regulation or
         contractual restriction binding on or affecting it or its property.

                  (c) All consents, authorizations and approvals required for
         the execution and delivery by Guarantor of this Guaranty and the
         performance of its obligations hereunder have been obtained and remain
         in full force and effect, all conditions thereof have been duly
         complied with, and no other action by, and no notice to or filing with,
         any governmental authority or regulatory body is required for that
         execution, delivery or performance.

                  (d) This Guaranty is Guarantor's legal, valid and binding
         obligation, enforceable against Guarantor in accordance with its terms,
         subject to applicable bankruptcy, insolvency and similar laws affecting
         creditors' rights generally, and subject to general principles of
         equity.

                  (e) The ultimate determination of all proceedings pending or,
         to the best of its knowledge, threatened against Guarantor at law or in
         equity or before any governmental instrumentality or in any arbitration
         will not, in the aggregate, materially impair its ability to perform
         its obligations under this Guaranty, and no such proceeding purports or
         is likely to affect the legality, validity or enforceability of this
         Guaranty.

                  (f) No proceeding has been instituted in a court seeking a
         decree or order (i) for relief in respect of Guarantor in an
         involuntary case under any applicable bankruptcy, insolvency or other
         similar law now in effect, or (ii) for the appointment of a receiver,
         liquidator, assignee, custodian, trustee or sequestrator (or other
         similar official) of Guarantor, or for any substantial part of
         Guarantor's property, in an involuntary case under any applicable
         bankruptcy, insolvency or other similar law now in effect, or (3) for
         the winding up or liquidation of the affairs of Guarantor.

                  (g) Guarantor has not (i) commenced a voluntary case under any
         applicable


<PAGE>   129


         bankruptcy, insolvency or other similar law now in effect, or (ii)
         consented to the entry of an order for relief in an involuntary case
         under any such law, or (iii) consented to the appointment of or taking
         possession by a receiver, liquidator, assignee, custodian, trustee or
         sequestrator (or other similar official) of Guarantor or for any
         substantial part of the property of Guarantor, or (iv) made a general
         assignment for the benefit of creditors, or (v) failed generally to pay
         its debts as they become due, or (vi) taken any corporate action in
         furtherance of any of the foregoing.

         6. Continuing Guaranty, Transfer; Assignment. This Guaranty is a
continuing guaranty and shall (i) be binding upon Guarantor, its successors and
assigns, and (ii) inure to the benefit of and be enforceable by Bank and its
successors, transferees and assigns. Without limiting the generality of the
foregoing, Bank may assign or otherwise transfer any evidence of any of the
Obligations to any other person or entity, and such person or entity shall
thereupon become vested with all the rights in respect thereof granted to Bank
herein or otherwise, provided, however, that each transferee or assignee shall
be bound by all waivers, notices and actions granted, given, taken and made
prior to the time of the assignment or transfer to it. The duties and
obligations of Guarantor may not be delegated or transferred by Guarantor
without the written consent of Bank.

         7. Validity; Amendments. If any provision hereof shall for any reason
be held invalid or unenforceable, no other provision shall be affected thereby,
and this Guaranty shall be construed as if the invalid or unenforceable
provision had never been a part of it; provided, however, that in no event shall
the liability of Guarantor be greater than as set forth in the penultimate
sentence of Section 1 hereof. No amendment or waiver of any provision of this
Guaranty nor consent to any departure by Guarantor therefrom shall in any event
be effective unless the same shall be in writing and signed by Bank, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. None of the terms or provisions of the
Letter of Credit Agreement may be waived, altered, modified or amended without
the prior written consent of Guarantor and this Guaranty shall be void as to any
such waiver, alteration, modification or amendment purported to be made without
such consent.

         8. Notices. All notices and other communications provided for hereunder
shall be in writing (including telegraphic communication) and, if to Guarantor,
mailed by first class, certified mail, or telecopied, or delivered to it, in
each case addressed to it at 2850 West Golf Road, 5th Floor, Rolling Meadows,
Illinois 60008, Attention: Contract Administration, with a copy to General
Counsel (telecopy number ___________________); and if to Bank, mailed by first
class, certified mail, or telecopied, or delivered to it, in each case addressed
to it at _________________________, Attention: ________________ (telecopy number
___________________), or as to each party at such other address as shall be
designated by such party in a written notice to the other party. All such
notices and other communications shall be effective three (3) days after being
deposited in the mails (except that a mailed notice pursuant to the second
sentence of Section 2(a) hereof shall only be effective upon actual receipt
thereof by Guarantor) or when telecopied (having received the answer back), or
when delivered by hand respectively, addressed as aforesaid.

         9. Governing Law. This Guaranty shall be governed by, and construed in
accordance 


<PAGE>   130


with, the laws of the State of Illinois, without regard to conflicts of law
principles.

         WITNESS the due execution hereof intending to be legally bound.

As of _________________, 19___

[BANK]
- ------------------------
- ------------------------
- ------------------------

Attention: _____________

Ladies and Gentlemen:

By its acceptance below, and subject to the terms of this Agreement,
____________________ (the "Letter of Credit Issuer") has agreed to issue, at the
request and for the account of __________________________________ ("Account
Party"), an irrevocable letter of credit substantially in the form of Exhibit I
hereto (as from time to time hereafter amended, the "Letter of Credit"), dated
on or about _____________, 19___, and with an expiry date of ________________,
19___ (as from time to time hereafter extended, the ("Expiry Date") in favor of
(NAME OF BENEFICIARY) (the "Beneficiary") in a maximum face amount equal to
$----------------.

The Account Party and the Letter of Credit Issuer hereby agree as follows with
respect to the Letter of Credit:

         1. Reimbursement Obligation. The Account Party hereby irrevocably and
unconditionally agrees with the Letter of Credit Issuer that in the event the
Letter of Credit Issuer shall make any payment to the Beneficiary under the
Letter of Credit, each payment shall constitute, without necessity of further
act or evidence whatsoever, an obligation (arising on the date payment is made
to the Beneficiary by the Letter of Credit Issuer) to reimburse the Letter of
Credit Issuer upon demand (the "Reimbursement Obligation") in the principal
amount equal to the amount of such payment. The Reimbursement Obligation will
bear interest at the rate per annum equal to the Reference Rate (as hereinafter
defined) plus 1.5% per annum from the date of payment to the Beneficiary under
the Letter of Credit, payable upon demand. To the extent that any monies are
received by the Letter of Credit Issuer in respect of the Reimbursement
Obligation and other amounts owed to the Letter of Credit Issuer pursuant to or
in connection with this Agreement, such monies shall be applied in such order of
application (whether to the principal amount of any Reimbursement Obligation or
interest, or both, or otherwise) as the Letter of Credit Issuer may from time to
time in its sole discretion elect. As used herein, the term "Reference Rate"
means, at any time, the rate then most recently announced by the Letter


<PAGE>   133


of Credit Issuer at _______________ as its reference rate.

         2. Letter of Credit Fee. The Account Party agrees to pay or cause to be
paid to the Letter of Credit Issuer a reasonable fee as agreed upon by such
parties, to be payable at such time or times as such parties agree. If any
payment of the fee is not made when due, then such fee shall bear interest until
paid at a rate per annum equal to 1/2 of 1% per annum, payable upon demand.

         3. Indemnifications. The obligation of the Account Party hereof to pay
such amounts shall be absolute, unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances
whatsoever, including, without limitation, the following circumstances:

                  (a) the existence of any claim, set-off, defense or other
         right which the Beneficiary, the Account Party, the Guarantor, the
         Letter of Credit Issuer or other person or entity may have at any time
         against the Beneficiary, the Account Party, the Guarantor, the Letter
         of Credit Issuer or any other person or entity for any reason
         whatsoever, whether in connection with this Agreement, the Letter of
         Credit, the Guaranty (as hereinafter defined) or any agreement or
         document referred to in any thereof or in connection with any unrelated
         transaction;

                  (b) any certificate presented under the Letter of Credit
         proving to be forged, fraudulent or invalid; or

                  (c) any other circumstance or happening whatsoever not
         constituting gross negligence or willful misconduct of the Letter of
         Credit Issuer, whether or not similar to any of the foregoing.

In addition, neither the Letter of Credit Issuer nor any of its directors,
officers, employees or agents shall have any liability or responsibility of any
kind to the Beneficiary, the Account Party, the Guarantor or any other person or
entity under or in connection with the Letter of Credit, in connection with any
acts or omissions of any of the foregoing persons or entities or in connection
with any payment or failure to make payment thereunder by the Letter of Credit
Issuer under any circumstances whatsoever, except that the Letter of Credit
Issuer shall be liable for the amount of any damages suffered by the Account
Party or the Guarantor which are caused by the Letter of Credit Issuer's willful
misconduct or negligence in performing its obligations under this Agreement or
the Letter of Credit (including in determining whether documents presented or
delivered under the Letter of Credit appear to comply with the terms of the
Letter of Credit). In furtherance and not in limitation of the foregoing, the
Letter of Credit Issuer may accept documents that appear on their face to be in
order, without responsibility for further investigation.

         4. Increased Costs/Taxes. If as a result of any law, regulation, treaty
or directive, or any change therein, or in the interpretation or application
thereof or the Letter of Credit Issuer's compliance with any request or
directive (whether or not having the force of law) from any court 


<PAGE>   134


or governmental authority, agency or instrumentality, any reserve, premium,
special deposit, special assessment or similar requirements against (a) the
Letter of Credit Issuer's assets, (b) deposits with the Letter of Credit Issuer
or for its account, or (c) credit extended by the Letter of Credit Issuer, are
imposed, modified or deemed applicable and the Letter of Credit Issuer
determines that, by reason thereof, the cost to it of issuing or maintaining the
Letter of Credit is increased, the Account Party agrees to pay to the Letter of
Credit Issuer upon demand (which demand shall be accompanied by a statement
setting forth the basis for the calculation thereof) such additional amount or
amounts as will compensate it for such additional cost. Determinations by the
Letter of Credit Issuer, for the purposes of this Section 5, of the additional
amounts required to compensate it in respect of the foregoing shall be
conclusive absent manifest error. The Account Party further agrees to pay any
applicable levies or other taxes imposed in connection with the Letter of Credit
other than net income taxes payable by the Letter of Credit Issuer.

         5. Guaranty. It is a condition precedent to the issuance of the Letter
of Credit that First Source Financial LLP, an Illinois registered limited
liability partnership (the "Guarantor"), execute and deliver to the Letter of
Credit Issuer a Guaranty substantially in the form of Exhibit II hereto (as from
time to time thereafter amended, the "Guaranty").

                                14. INFRINGEMENT
                                    ------------

         14.1 In the event that either party shall learn of an infringement of
any PATENT or TRADEMARK (including any act of unfair competition), that party
shall call the other party's attention thereto in writing and shall provide such
other party with reasonable evidence of such infringement. Both parties shall
use their best efforts in cooperation with each other to terminate such
infringement without litigation. If the efforts of the parties are not
successful in abating the infringement within sixty (60) days after the
infringer has been formally notified of the infringement, LICENSEE shall have
the right to:

              14.1.1 Commence suit on LICENSEE's own account for infringement of
its exclusive rights, subject to LICENSOR's right to fully participate in such
suit, at its own cost, in order to protect its rights;

              14.1.2 Join with LICENSOR in such suit if LICENSOR brings suit
pursuant to Section 14.2 below or;

              14.1.3 Refuse to bring such suit; and LICENSEE shall give notice

its own account, if LICENSEE elects not to commence or join in any suit.

         14.3 Such legal action as is decided upon shall be at the expense of
the party bringing suit, and all recoveries recovered thereby shall belong to
such party, provided, however, that legal action brought jointly by LICENSOR and
LICENSEE and fully participated in by both shall be at the joint expense of the
parties, and all recoveries up to the amount of such expense, shall be shared
jointly by them in proportion to the share of expense paid by each party, and in
the event such recoveries include damages or royalties in excess of expenses,
the amount in excess of expenses shall be shared by the parties on a
proportional basis as to their actual losses (for LICENSEE, lost gross profit;
for LICENSOR, lost royalties).

         14.4 Each party agrees to cooperate, in all reasonable respects as
requested by the other party in litigation proceedings instituted hereunder and,
upon request of the party bringing suit, the other party shall make available to
the party bringing suit all relevant records, papers, information, samples,
specimens, and the like which may be relevant and in its possession. The party
bringing suit and incurring the majority of the associated costs shall have the
right to control such litigation.

         14.5 In the event the making, using or selling of PRODUCTS is
determined by a court of competent jurisdiction to infringe one or more claims
of a patent(s) owned by a third party, no royalty payments shall be due LICENSOR
from the date such lawsuit is filed with respect to NET SALES in the territory
where such third party's patent rights are applicable. All royalty payments
shall be placed in an interest-bearing escrow account from the date that the
lawsuit is filed and maintained therein until final judgment. Provided, however,
that if such infringement results in a license to LICENSEE which enables
LICENSEE to continue making, using, or selling such PRODUCT in such part of the
territory, then the royalty payments due to LICENSOR with respect to NET SALES
in such territory following the date such lawsuit is filed or such settlement is
reached shall be reduced by the damages and/or royalty payments paid or to be
paid to such third party and the royalty payments to LICENSOR shall commence
only after the full recovery by LICENSEE of its reasonable costs and expenses in
defending such suit. In no event shall LICENSOR's earned royalty be reduced to
less than [*] due to earned royalty payments made to third parties by LICENSEE.

         Should LICENSEE, be required to make additional payments to a third
party under this Section 14.5, the minimum royalty requirements provided for in
section 3.3 shall not longer apply.


                            15. TERM AND TERMINATION
                                --------------------

         15.1 This Agreement shall become effective as of the date first written
above, and shall continue until December 31, 1999, (INITIAL TERM), unless sooner
terminated as provided for under this Agreement. Thereafter, the term shall be
renewed for an additional five (5)-year term (RENEWAL TERM) provided that [*].
Upon expiration of the RENEWAL TERM, the term shall be renewed until the last to
expire United States PATENT (either the term of such patent has expired or the
relevant claims have been held invalid by a court of competent jurisdiction)
which has claims covering such PRODUCT provided that LICENSEE has made total
cumulative payments to LICENSOR of [*]. Upon expiration, LICENSEE's license
herein shall be fully paid and irrevocable, however, any unpaid but accrued
royalties shall still be due and payable to LICENSOR.

prior written notice to LICENSOR.

         15.3 Either party may terminate this Agreement by notice to the other
party in the event of a material breach by such other party of its obligations
hereunder, which breach such other party has failed to cure within thirty (30)
days, in the case of any breach in the payment of amounts required hereunder, or
sixty (60) days, in the case of any other breach, after notice thereof.

         15.4 The following rights and obligations survive any termination of
this Agreement to the degree necessary to permit their complete fulfillment or
discharge:

              15.4.1 LICENSOR's rights to receive or recover, and LICENSEE's
obligations to provide reports as specified in Article 5 hereof and to pay
royalties accrued or accruable for payment at the time of any termination.

              15.4.2 LICENSEE's obligation to maintain records as provided in
Article 5 hereof and LICENSOR's right to conduct a final audit thereof.

              15.4.3 LICENSEE's right to complete the sale or distribution of
all PRODUCTS in inventory or in the process of being manufactured including the
right to sell or distribute any components of PRODUCTS to minimize its losses,
subject to LICENSEE's payments of royalties to LICENSOR as provided for herein,
provided, however, LICENSOR shall have the right to purchase all of such
PRODUCTS and inventory or in the process of being manufactured (collectively,
the "Remaining Inventory") under terms consistent with those terms then provided
by LICENSEE to its sub-licensees or customers for similar products. Within
twenty (20) days of any such termination, LICENSEE shall advise LICENSOR of the
amount of such Remaining Inventory, as well as the terms of purchase of same,
and LICENSOR shall have ten (10) days to advise LICENSEE of its intentions with
regard to the purchase of such Remaining Inventory. To the extent LICENSOR
elects to purchase such Remaining Inventory by notice to LICENSEE within such
time period, LICENSEE shall not have the right to sell or distribute same but
shall sell such Remaining Inventory to LICENSOR (such sales shall be non-royalty
bearing); to the extent LICENSOR does not so elect to purchase such Remaining
Inventory, LICENSOR shall have the right to sell and/or distribute same.

              15.4.4 Any cause of action or claim of either party accrued
because of any breach or default by the other party.

         15.5 Upon termination of this Agreement, LICENSEE agrees to return to
LICENSOR all prototype specimens, slides, blueprints and other materials
provided by LICENSOR to LICENSEE. LICENSEE shall return such material to
LICENSOR no later than ninety (90) days after the termination of this Agreement.

         15.6 Upon termination and except as expressly set forth in this Section
15.4, LICENSEE acknowledges that neither it nor any of its AFFILIATES shall have
any rights whatsoever with regard to the INFORMATION, PATENTS, and/or the
TRADEMARKS, or to

shall automatically revert to and be the exclusive property of LICENSOR.

consultants and third party vendors under similar terms and conditions to those

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

         THIS AGREEMENT made and effective this 11th day of April, 1995, by and

92687 ("LICENSEE").

                               W I T N E S S E T H
                               -------------------

         WHEREAS, LICENSOR and LICENSEE entered into a License Agreement
effective April 28, 1994 (the "1994 AGREEMENT") wherein LICENSOR granted
LICENSEE exclusive rights to manufacture, use, and sell certain dental
restorative products known as THE DIA ANATOMICAL ABUTMENT SYSTEM according to
the terms and conditions therein set forth;

         WHEREAS, Section 10.3 of the 1994 AGREEMENT provided LICENSEE with
rights: (a) to include products which are within the scope of the patent
properties listed in Exhibit A-2 of the that AGREEMENT as "PRODUCTS" (those
products being known as "THE NEW PRODUCTS") and (b) to include the patent
properties specified in Exhibit A-2 of the 1994 AGREEMENT as "PATENTS"; and

         WHEREAS, LICENSEE has notified LICENSOR of its desire to acquire the
rights described above and the parties have negotiated the consideration and the
terms related to LICENSEE's acquisition of such rights;

         NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein, the parties hereto hereby agree as follows:

         1. The term "PATENTS" as used in the 1994 AGREEMENT shall hereinafter
include each United States patent application listed on Exhibit A-2 of the 1994
AGREEMENT and each patent issuing upon such patent applications; each non-United
States patent and patent application corresponding to the foregoing; and each
divisional, reissue, continuation, renewal, and extension of the foregoing.

         2. LICENSOR represents and warrants that Exhibit B-1 attached hereto is
a complete and accurate listing of all patent properties included within PATENTS
as of the effective date of this Addendum and that Exhibit B-2 is a complete and
accurate listing of all products to be added under this Addendum.

         3. The term "PRODUCTS" as used in the 1994 AGREEMENT shall mean all
products within the scope of any valid claim of PATENTS.

         4. As reimbursement for its development and patent costs, LICENSEE
shall pay LICENSOR the following: [*]. LICENSEE agrees to use reasonable, good
faith efforts to overcome any regulatory issues that may arise and to use
reasonable, good faith efforts to resolve any assertion that the making, using,
or selling of PRODUCTS infringe one or more claims of a patent owned by a third
party. LICENSOR agrees to provide LICENSEE with reasonable assistance,
cooperation and consultation in overcoming any regulatory issues that may arise
and in resolving any assertion that the making, using, or selling of PRODUCTS
infringe one or more claims of a patent owned by a third party. Nothing in this
Paragraph 4 shall limit in any way LICENSEE's rights under the 1994 AGREEMENT,
especially Section 14.5 of that AGREEMENT.

         5. Commencing with the first sale of a NEW PRODUCT, the table set forth
in Section 3.3 of the 1994 AGREEMENT will be replaced with the following:


         12-Month Period                           Annual Minimum Royalty
         ---------------                           ----------------------

Fiscal Year ending Dec. 31, 1994                             [*]

Fiscal Year ending Dec. 31, 1995                             [*]

Fiscal Year ending Dec. 31, 1996                             [*]

Fiscal Year ending Dec. 31, 1997                             [*]

Fiscal Year ending Dec. 31, 1998                             [*]

Fiscal Year ending Dec. 31, 1999                             [*]


         6. LICENSEE agrees to pay LICENSOR's clinicians, [*] provided under
Section 5.3 of the 1994 AGREEMENT during the 12-month period commencing with the
effective date of this Addendum. This will be renewable on an annual basis at
the sole discretion of the LICENSEE during the initial term of the 1994
AGREEMENT. [*].

         7. The parties agree that new product ideas should be presented to
LICENSEE before LICENSOR or its clinicians incur significant product development
costs. Accordingly, Section 10.2 of the 1994 AGREEMENT is amended to read as
follows:

         Whenever LICENSOR conceives a new product, LICENSOR shall notify
         LICENSEE of same in writing; this notification shall follow LICENSOR
         having filed a patent application covering such new product, [*].
         LICENSEE shall have ninety (90) days from the date of such notice to
         inform LICENSOR of its desire to license such product under reasonable
         terms and conditions to be mutually agreed upon, such terms and
         conditions to include, without limitation, reimbursement of said
         development and patent costs and such other sums as the parties shall
         negotiate. If LICENSEE and LICENSOR are unable to agree on suitable
         terms and conditions for such license within ninety (90) days from the
         end of such first ninety (90)-day period, LICENSOR shall be free to
         negotiate with

         third parties. However, prior to executing a license with any third
         party on terms more favorable than those last offered to LICENSEE for
         such products, LICENSEE shall have the right to license such Products
         under the same terms and conditions as the terms and conditions
         LICENSOR would have granted to such third party. All disclosures of new
         information and products under this Section 10.2 shall be under
         suitable terms of confidentiality and a separate non-disclosure
         agreement shall be executed by the parties for each such new product.

         8. If LICENSEE grants a sublicense under Section 2.1 of the 1994
AGREEMENT to a third party (any party other than one of LICENSEE's AFFILIATES as
defined in Paragraph 1.1 of the 1994 AGREEMENT) (said party referred to herein
as a "Third PARTY"), [*] relative to the PRODUCTS shall be payable by LICENSEE
to LICENSOR. Such payments shall be made quarterly with an accounting
substantially equivalent to that provided to LICENSOR relative to LICENSEE's
direct sale of PRODUCTS. Royalties and proceeds shall include sums received by
LICENSEE from the Third Party, less LICENSEE's direct, out-of-pocket expenses
solely attributable to the Third Party sublicense or grant. It is understood
that sale of PRODUCTS shall not constitute a sublicense within the meaning of
this Paragraph 8.

         9. The terms of the 1994 AGREEMENT shall continue in full force and
effect except as modified herein. If there is any inconsistency between the
terms of the 1994 AGREEMENT and the terms of this Addendum, the terms of this
Addendum shall control.
