                  PURCHASE, SALE AND TERMS OF NOTE; PAYMENTS
                  ------------------------------------------

     Section 2.1. Description of Notes. The Company has authorized the issuance
and sale to the Purchaser of up to $3,000,000 aggregate principal amount of its
11% Subordinated Notes (individually, a "Note" and collectively, the "Notes").
The Notes shall be substantially in the form set forth as Exhibit 2.1 (including
any Note or Notes delivered in exchange or replacement therefor). The Notes
shall be due and payable on July 1, 2001, except to the extent they are subject
to earlier acceleration as provided therein. The Notes shall become immediately
due and payable upon any Change in Control of the Company; provided, however,
that a reincorporation by the Company under the laws of the State of Delaware,
or a merger into a newly-formed corporation incorporated under Delaware law,
shall not trigger acceleration of the Notes. The Notes shall bear interest
(based on a 360-day year counting actual days elapsed) on the unpaid principal
amount thereof until due and payable at the rate of 11% per annum. Interest
shall accrue from the date of issuance of the Notes and be payable (y) monthly
in arrears on the first day of each month, commencing on the first day of

                                      -5-
<PAGE>

the first month following execution and delivery of each Note, and (z) at
maturity or prior prepayment of the Notes in full.

     Section 2.2. Commitment. The Company agrees to issue and sell to the
Purchaser, and, subject to and in reliance upon the representations, warranties,
terms and conditions contained in this Agreement, the Purchaser agrees to
purchase the Notes as set forth below:

     (a)  Initial Funding. On the date on which this Agreement is executed and
delivered (the "Closing Date"), the Company shall sell and the Purchaser shall
purchase a Note in the original principal amount of not less than $1,500,000.

     (b)  Subsequent Funding. For a period of 12 months after the Closing Date,
subject to the terms and conditions set forth in this Agreement and the Notes,
the Company may request that the Purchaser purchase additional Notes in an
aggregate original principal amount of up to $1,500,000. The Company shall
determine the amount and dates of these subsequent purchases of the Notes (each,
a "Purchase Date") by delivering in writing to the Company no later than ten
Business Days prior to each requested Purchase Date. Each subsequent Note, if
any, shall be in an aggregate principal amount of not less than $500,000.
Purchaser's obligation to purchase Notes on any Purchase Date shall be expressly
conditioned upon the Company's ongoing compliance with all of the terms and
conditions set forth in this Agreement and the other Investment Documents.

     (c)  Minimum Balance Outstanding. During the term of the Notes, the Company
shall maintain a minimum, aggregate, outstanding balance due and payable under
the Notes of $1,500,000.

     Section 2.3. Issue Price; Original Issue Discount. Having considered all
facts relevant to a determination of the value of the Notes and the Warrants
being acquired by the Purchaser, including among other things the leveraged
nature of the Company's capitalization and the nature of its business and
prospects, the Company and the Purchaser have concluded and do hereby agree
that, within the meaning of Section 1273 of the Internal Revenue Code of 1986,
as amended (the "Code"), the issue price for the aggregate principal amount of
the Notes is $2,850,000, and this amount will be allocated pro rata based on the
principal amount of each Note issued pursuant to this Agreement. The Company and
the Purchaser recognize that this Agreement creates original issue discount in
the aggregate amount of $150,000 (and this amount will be allocated pro rata
based on the principal amount of each Note issued pursuant to this Agreement),
which is the amount to be taken into account by the Company and the Purchaser
for federal income tax purposes on the Notes, and they agree to adhere to this
Agreement for that purposes and not to take any action inconsistent herewith.

     Section 2.4. Use of Proceeds. The Company agrees to use the full proceeds
from the sale of the Notes for working capital and general corporate purposes
and for any other purposes approved by the Board of Directors.

     Section 2.5. Prepayment. The Company may prepay all or any portion of the
unpaid principal balance and accrued interest of any Note without premium or
penalty. However, all sums received

                                      -6-
<PAGE>

in prepayment shall first be applied in payment of accrued but unpaid interest,
and the excess, if any, shall then be applied to the unpaid principal balance
due under the Note.

     Section 2.6. Payments and Endorsements. Payments of principal and interest
on the Notes shall be made without setoff or counterclaim directly by wire
transfer of funds to the account or accounts designated in writing by the
Purchaser, without any presentment or notation of payment, except that prior to
any transfer of the Notes, the holder thereof shall endorse on that Note a
record of the date to which interest has been paid and all payments made on
account of principal of that Note. If at any time more than one Note is
outstanding, then all payments and prepayments of principal of and interest on
the Notes shall be applied (to the extent thereof) to all holders of the Notes
pro rata based on the principal amount outstanding and held by each holder.

     Section 2.7. Maximum Legal Rate of Interest. Nothing in this Agreement or
in the Notes shall require the Company to pay interest at a rate in excess of
the maximum rate permitted by applicable law.

     Section 2.8. Payment on Non-Business Days. Whenever any payment is due on a
day other than a Business Day, that payment may be made on the next succeeding
Business Day, and the extension of time shall be included in the computation of
interest due.

     Section 2.9. Transfer and Exchange of Note. The Notes may not be sold,
transferred, assigned, hypothecated or otherwise disposed prior to maturity or
prepayment thereof, without the prior consent of the Company; provided, however,
that the Purchaser may transfer or assign the Notes, or its interest therein, to
a limited partner or general partner of the Purchaser in connection with the
liquidation, dissolution, or winding up of the affairs of the Purchaser
("Permitted Transfer"). In the event of a Permitted Transfer, the holder
desiring to transfer or exchange any Note shall first notify the Company in
writing of that transfer or exchange at least two Business Days prior to the
desired date of transfer or exchange (the "Transfer Notice"). Within a
reasonable time after the Transfer Notice and without expense (other than
transfer taxes, if any) to that holder, the Company shall issue in exchange
therefor subject to Section 5.1, another Note or Notes, in the denominations as
requested by the holder, for the same aggregate principal amount, as of the date
of the issuance, as the unpaid principal amount of the Note or Notes surrendered
and having the same maturity and rate of interest, containing the same
provisions, and subject to the same terms and conditions as the Note or Notes
surrendered. Each new Note shall be made payable to that Person or Persons, or

principal or interest shall result therefrom.

the Company of the loss, theft, destruction, or mutilation of any Note and, if
requested in the case of any loss, theft, or destruction, upon delivery of an

Company, or, in the case of any mutilation, upon surrender and cancellation of
the Note, the Company will issue a new Note, at the expense of the holder, of

Note. If any Note of which the Purchaser, its nominee, or any of its partners is
the holder is lost, stolen, or destroyed, the affidavit of an authorized partner
or officer of the holder setting forth the circumstances with respect to that
loss, theft, or destruction shall be accepted as satisfactory evidence thereof,
and no indemnification bond or other security shall be required as a condition
to the execution and delivery by the Company of a new Note in replacement of
that lost, stolen, or destroyed Note other than the holder's written agreement
to indemnify the Company.

Purchaser's reservation of sufficient funds to lend the principal amount of the
Notes to the Company and for entering into the Investment Documents (the
"Commitment Fee"). The Commitment Fee may be paid to the Purchaser by means of a
deduction from the proceeds from the Note or Notes purchased at the Closing.

     Section 2.13. Default Rate of Interest. If an Event of Default occurs and

permitted by applicable law; provided, however, that upon the cessation or cure
of the Event of Default, if no other Event of Default is then continuing, the
Note shall again bear interest at the rate of 11% per annum as set forth in
Section 2.1.

inducement to the Company to enter into and consummate the transactions
contemplated by this Agreement, the Purchaser hereby represents and warrants
that:

     (a)  The Purchaser has duly authorized, executed, and delivered this
Agreement and those Investment Documents that require execution by the
Purchaser.

     (b)  It is the Purchaser's present intention to acquire the Securities for
its own account.

     (c)  The Securities are being and will be acquired for the purpose of
investment and not with a view to distribution or resale thereof.

Company's business, affairs, and current prospects with those officers and
others as it has deemed appropriate or desirable in connection with the
transactions contemplated by this Agreement. The Purchaser further acknowledges
that it has requested, received, and reviewed that information, and that it has
undertaken an investigation and made further inquiries of officers of the
Company and others as it has deemed appropriate or desirable in connection with
the transactions; provided, however, that no investigation made at any time by

representations and warranties of the Company hereunder, which will survive any
investigation.

     (e)  The Purchaser understands that it must bear the economic risk of its
investment for an indefinite period of time because the Securities are not, and
will not be, registered under the Securities Act or any applicable state
securities laws and may not be resold unless subsequently registered under the
Securities Act and any other laws or unless an exemption from registration is
available. The Purchaser also understands that it is not contemplated that any

or that the Company will take all

                                      -10-
<PAGE>

reasonable steps which will make the provisions of Rule 144 under the Securities
Act available to permit resale of the Securities.

     (f)  The Purchaser represents that it has sufficient knowledge and
experience in financial and business matters so that it is capable of evaluating
the merits and risks of its investment in the Securities. The Purchaser further
represents that it is an "accredited investor" as that term is defined in Rule
501 of Regulation D of the Commission under the Securities Act and Indiana Code
23-2-1-1-(a) with respect to the purchase of the Securities.

     (g)  No Person has or will have, as a result of the transactions

upon the Company for any commission, fee or other compensation as a finder or
broker because of any act or omission by the Purchaser or any agent of the
Purchaser except as provided in Section 2.12.

     (h)  The Purchaser hereby acknowledges that the Notes, the Warrants, each
certificate representing Warrant Shares, and any other securities issued in
respect of the Warrant Shares upon any stock split, stock dividend,
recapitalization, merger, or similar event (unless no longer required in the
opinion of counsel to the Company) shall bear a legend substantially in the
following form:

     [THIS] [NOTE] [WARRANT] [HAS] [THESE SHARES HAVE] NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE OR OTHER SECURITIES
     LAWS, AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, OR ASSIGNED EXCEPT (i)
     PURSUANT TO REGISTRATIONS UNDER APPLICABLE SECURITIES LAWS, OR (ii) IF, IN
     THE OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY, THE PROPOSED
     TRANSFER MAY BE EFFECTED IN COMPLIANCE WITH ALL APPLICABLE SECURITIES LAWS,
     WITHOUT REGISTRATION.

The acquisition by the Purchaser of the Securities shall constitute a
confirmation by it of the foregoing representations.

     Section 5.2. Transferees Bound. The Purchaser understands and acknowledges
with the Company that the Company shall not issue or transfer any Note, Warrant,
or Warrant Shares unless the Person to whom they are being issued or transferred
shall deliver to the secretary of the Company written representations
substantially similar to those in Section 5.1 or other representations of its
investment intent and experience as are reasonably acceptable to counsel for the
Company.

                               EVENTS OF DEFAULT
                               -----------------

     Section 8.1.  Events of Default. Each of the following events constitute
"Events of Default" for purposes of this Agreement:

     (a)  The Company fails to pay any installment of principal of or interest
on the Notes when due, and that failure continues for ten days.

     (b)  Any representation or warranty made by the Company in this Agreement
(or by any of its officers) in any certificate, instrument, or written statement
contemplated by or made or delivered pursuant to or in connection with this
Agreement, proves to have been incorrect in any material respect when made.

     (c)  The Company fails to perform or observe any other term, covenant or
agreement contained in this Agreement, the Notes, or the Warrants on its part to
be performed or observed, and any that failure remains unremedied for (i) ten
days after the Company receives written notice from the registered holder of the
Notes as to a payment default, and (ii) 30 days after the Company receives
written notice from the registered holder of the Notes as to defaults other than
payment defaults.

     (d)  The Company fails to pay any Indebtedness for borrowed money exceeding
$250,000 (other than as evidenced by the Notes) owing by the Company, or any
interest or premium thereon, when due (or, if permitted by the terms of the
relevant document, within any applicable grace period), whether the Indebtedness
shall become due by scheduled maturity, by required prepayment, by acceleration,
by demand or otherwise.

     (e)  The Company fails to perform any material term, covenant, or agreement
on its part to be performed under any agreement or instrument (other than this
Agreement or the Notes) evidencing or securing or relating to any Indebtedness
owing by the Company, as the case may be, when required to be performed (or, if
permitted by the terms of the relevant document, within any applicable grace
period), if the effect of the failure to pay or perform is to accelerate, or to
permit the holder or holders of the Indebtedness, or the trustee or trustees
under any agreement or instrument to accelerate the maturity of the
Indebtedness, unless the holder or holders of the Indebtedness or the trustee or
trustees waive the failure to pay or perform.

     (f)  The Company has financial difficulties as exclusively evidenced by (i)
its failure generally to pay or its inability to pay its debts as they become
due; (ii) admitting in writing its inability to pay its debts generally as they
become due; (iii) commencement of a voluntary case under Title 11 of the United
States Code ("Title 11") as from time to time in effect, or by its authorizing,
by appropriate proceedings of its board of directors or other governing body,
the commencement of a voluntary case; (iv) filing an answer or other pleading
admitting or failing to deny the material

                                      -32-
<PAGE>

allegations of a petition filed against it commencing an involuntary case under
Title 11, or seeking, consenting to or acquiescing in the relief therein
provided or by its failing to controvert timely the material allegations of any
petition; (v) the entry of an order for relief in any involuntary case commenced
under Title 11; (vi) seeking relief as a debtor under any applicable law, other
than Title 11, of any jurisdiction relating to the liquidation or reorganization
of debtors or to the modification or alteration of the rights of creditors, or
by its consenting to or acquiescing in that relief; (vii) the entry of an order
by a court of competent jurisdiction (a) finding it to be bankrupt or insolvent,
(b) ordering or approving its liquidation, reorganization, or any modification
or alteration of the rights of its creditors, or (c) assuming custody of, or
appointing a receiver or other custodian for, all or a substantial part of its
property; or (viii) making an assignment for the benefit of, or entering into a
composition with, its creditors, or appointing or consenting to the appointment
of a receiver or other custodian for all or a substantial part of its property.

     (g)  Any judgment, writ, warrant of attachment or execution or similar
process is issued or levied against a substantial part of the property of the
Company, and that judgment, writ, or similar process is not released, vacated,
or fully bonded within 60 days after its issue or levy.

     (h)  The Company breaches any of its material obligations under the Amended
and Restated Voting and Co-Sale Agreement, or the Amended and Restated
Registration Rights Agreement.

     Section 8.2.  Remedies. If an Event of Default occurs and is continuing,
then:

     (a)  the Purchaser may, by notice to the Company, declare the entire unpaid
principal amount of the Note, all interest accrued, and unpaid thereon, and all
other amounts payable under this Agreement to be forthwith due, and payable,
whereupon the Note, all accrued interest, and all those amounts shall become and
be forthwith due and payable (unless an Event of Default has occurred under
Subsection 8.1(h) in which case all those amounts shall automatically become due
and payable), without presentment, demand, protest, or further notice of any
kind, all of which the Company hereby expressly waives; and

     (b)  the Purchaser may proceed to protect and enforce its rights by suit in
equity (including without limitation a suit for rescission), action at law,
and/or other appropriate proceeding either for specific performance of any
covenant, provision, or condition contained or incorporated by reference in this
Agreement or any term of the Articles of Incorporation of the Company, or in aid
of the exercise of any power granted in this Agreement or in the Amended and
Restated Articles of Incorporation of the Company, and, immediately, in the case
of Section 8.1(h).

     Without in any way limiting the rights of the holders of the Note, the
Company hereby agrees that the holders of the Warrants or the Warrant Shares
would have no adequate remedy at law, for monetary compensation or otherwise,
for the damages that would be suffered if the Company failed to comply with its
obligations under the Warrants, and that the Company therefore agrees that the

                                      -33-
<PAGE>

holders of the Warrants and the Warrant Shares shall be entitled to obtain
specific performance of the Company's obligations under the Warrants and this
Agreement.

     Section 8.3. Annulment of Defaults. Section 8.1 is subject to the condition
that if there is an Event of Default, then, and in every case the holders of
66.67% or more in principal amount of all Notes then outstanding may, by written
instrument filed with the Company, rescind, and annul the declaration and its
consequences; but, no rescission or annulment shall extend to or affect any
subsequent default or Event of Default or impair any other right of the
Purchaser.

                                  ARTICLE IX

                                 MISCELLANEOUS
                                 -------------

     Section 9.1. Amendment and Certain Waivers. This Agreement may be amended
or modified only by a written agreement executed by the Company and (i) as to
the Notes, the holder or holders of at least 66.67% in principal amount of all
Notes then outstanding, and (ii) in the case of the Warrants or Warrant Shares,
the holder or holders of at least 66.67% of the Warrant Shares issued and
issuable upon exercise of the Warrants. In each case of an amendment or
modification, copies of the consents of the holder(s) of the Notes and the
Warrants or Warrant Shares, as the case may be, shall be delivered to each other
holder of the Notes and the Warrants or Warrant Shares. No consent will be
effective to reduce or to postpone the date fixed for the payment of the
principal (including any required redemption) or interest payable on any Notes
without the consent of the holder thereof or to alter or amend the consent
mechanism provided for under this Section 9.1.

     Section 9.2. Benefit of Parties; Assignability. All of the terms and
conditions of this Agreement shall be binding upon and inure to the benefit of
the parties and their respective successors and assigns; provided, however, that
the Company may not delegate its responsibilities or assign its rights under
this Agreement without the prior written consent of (i) as to the Notes, the
holder or holders of at least 66.67% in principal amount of all Notes then
outstanding, and (ii) in the case of the Warrants or Warrant Shares, the holder
or holders of at least 66.67% of the Warrant Shares issued and issuable upon
exercise of the Warrants.

     Section 9.3. Confidentiality. Except as specified in Section 7.1(h), the
Purchaser agrees to use reasonable efforts to keep confidential all information
provided to it under the terms and conditions of this Agreement and which is not
in the public domain. No party to this Agreement shall make any public
announcement of the transactions provided for in or contemplated by this
Agreement unless the form and substance of the announcement is mutually agreed
upon by all parties, which agreement shall not be unreasonably withheld or
delayed, or unless public disclosure is required by law.

     Section 9.4. Cooperation. The parties agree that after the Closing they
will from time to time, upon the request of any other party and without further
consideration, execute, acknowledge, and deliver in proper form any further
instruments and take such other action as any other party may

                                      -34-
<PAGE>

reasonably require to carry out effectively the transactions contemplated by
this Agreement and the Investment Documents.

     Section 9.5. Counterparts. This Agreement may be executed simultaneously in
two or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

     Section 9.6. Cumulative Remedies and Survival. The rights and remedies
specified in this Agreement shall not be exclusive of any other right or remedy
and shall be cumulative and in addition to every other right or remedy now or
hereafter existing at law or in equity or by statute or otherwise that may be
available to the Purchaser and the holders of the Notes, Warrants, and Warrant
Shares. All representations and warranties of the Company in this Agreement and
the Investment Documents shall indefinitely survive the execution and delivery
of this Agreement and the Investment Documents. No investigation or review
carried out by or on behalf of the Purchaser shall impair the right of the
Purchaser to rely upon the representations and warranties in this Agreement and
the Investment Documents in accordance with their terms.

     Section 9.7. Entire Agreement. This Agreement (including the Schedules
referred to and incorporated by reference herein that form a part of this
Agreement), and the Investment Documents contain the entire understanding of the
parties with respect to the subject matter hereof and thereof. There are no
representations, promises, warranties, covenants, or undertakings other than
those expressly set forth or provided for herein and therein. This Agreement and
the Investment Documents supersede all prior agreements and understandings
between the parties with respect to the transactions contemplated by this
Agreement and the Investment Documents, including but not limited to the
commitment letter between the Company and the Purchaser.

     Section 9.8. Governing Law and Choice of Forum. All questions concerning
the relative rights of the Company and its shareholders shall be governed by the
laws of the State of Illinois. Illinois law shall govern the interpretation,
construction, and enforcement of this Agreement and all transactions and
agreements contemplated hereby, notwithstanding any state's choice of law rules
to the contrary.

     Section 9.9. Indemnification. The Company agrees to indemnify, and hold
harmless the Purchaser, its subsidiaries, directors, officers, partners,
counsel, and employees (each, an "Indemnified Person"), from, and against any,
and all liability (including, without limitation, reasonable legal fees incurred
in defending against any liability) under, arising out of or are based upon (i)
the falsity or incorrectness as of the Closing Date of any representation or
warranty of the company contained in or made pursuant to the Investment
Documents; or (ii) the existence of any condition, event, or fact constituting,
or which with notice or passage of time, or both, would constitute a default in
the observance of any of the Company's undertakings or covenants under or
pursuant to the Amended and Restated Articles of Incorporation.. The obligations
of the Company under this Section 9.9 shall survive, and continue to be in full
force, and effect notwithstanding (a) the repayment of the Notes, and (b) the
termination of this Agreement. If any litigation or proceeding is brought
against any

                                      -35-
<PAGE>

Indemnified Person in respect of which indemnity may be sought against the
Company pursuant to this Section 9.9, the Indemnified Person shall promptly
notify the Company in writing of the commencement of the litigation or
proceeding. In case any litigation or proceeding shall be brought against any
Indemnified Person, and the Indemnified Person shall notify the Company of the
commencement of the litigation or proceedings, the Company shall be entitled to
participate in the proceedings, and, to the extent that it wishes, jointly with
any other similarity notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the Indemnified Person.

     Section 9.10. Interpretation. The terms and conditions of this Agreement
represent the results of bargaining and negotiations among the parties, each of
which has been represented by counsel of its own selection, and none of which
has acted under duress or compulsion, whether legal, economic or otherwise, and
represent the results of a combined draftsmanship effort. Consequently, the
terms and conditions hereof shall be interpreted and construed in accordance
with their usual and customary meanings and the parties hereby expressly waive
and disclaim in connection with the interpretation and construction hereof any
rule of law or procedures requiring otherwise, specifically including but not
limited to any rule of law to the effect that ambiguous or conflicting terms or
conditions contained herein shall be interpreted or construed against the party
whose counsel prepared this Agreement or any earlier draft hereof.

     Section 9.11. Knowledge of the Company. As used in this Agreement, the
phrase "to the knowledge of the Company" and phrases of similar import shall
mean, and shall for all purposes be construed as, the collective actual
knowledge of the officers and directors of the Company other than those
directors representing the Purchaser.

     Section 9.12. Notices. All notices, requests, demands, or other
communications that are required or may be given pursuant to the terms of this

or, as to each of the foregoing, at any other address as shall be designated by
that Person in a written notice to the other party complying as to delivery with
the terms of this Section.

     Section 9.13. Payments in Respect of Notes. The Purchaser, and any
successor holder of the Notes, by their acceptance thereof, agree that, with
respect to all sums received by them applicable to the payment of principal of
or interest on the Notes, equitable adjustment will be made among them so that,
in effect, all sums shall be shared ratably by all of the holders of the Notes
whether received by voluntary payment, by realization upon security, by the
exercise of the right of setoff, by counterclaim or cross-action or by the
enforcement of any or all of the Notes. If any holder of the Notes receives any
payment on its Notes in excess of its pro rata portion, then the holder
receiving the excess payment shall purchase for cash from the other holders an
interest in their Notes in those amounts as shall result in a ratable
participation by all of the holders in the aggregate unpaid amount of Notes then
outstanding. The Company shall not have any obligation to any Person under this
Section 9.14.

     Section 9.14. Payments in Respect of Warrant. The Purchaser, and any
successor holder of the Warrants, by their acceptance thereof, agree that, with
respect to the sale to, or repurchase by, the Company or any Person directly or
indirectly affiliated with the Company or any of its directors, officers, or
shareholders, of the Warrants, equitable adjustment will be made among the
holders of the Warrants so that in effect all sums so received shall be shared
ratably in proportion to their respective holdings of Warrants. If any holder of
the Warrants receives any sum in respect of its Warrants in excess of its pro
rata portion, then the holder receiving the excess shall purchase for cash from
the other holders of the Warrants an interest in their Warrants in that amount
as shall result in a ratable participation of all of the holders in the
aggregate of all Warrants then outstanding. The Company shall not have any
obligation to any Person under this Section 9.15.

     Section 9.15. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be
prohibited by or invalid under applicable law, that provision will be

                                      -37-

ineffective only to the extent of the prohibition or invalidity, without
invalidating the remainder of this Agreement.

     Section 9.16. Table of Contents and Captions. The Table of Contents and
captions of the Articles and Sections of this Agreement are solely for
convenient reference and shall not be deemed to affect the meaning or
interpretation of any provision of this Agreement.

     Section 9.17. Validity of Provisions. Should any part of this Agreement for
any reason be declared by any court of competent jurisdiction to be invalid,
that decision shall not affect the validity of the remaining portion, which
shall continue in full force and effect as if this Agreement had been executed
with the invalid portion eliminated, it being the intent of the parties that
they would have executed the remaining portion of the Agreement without
including any part or portion that may for any reason be declared invalid.

     Section 9.18. Waiver of Breach. Neither any waiver of any breach of, nor
any failure to enforce any term or condition of, this Agreement shall operate as
a waiver of any other breach of any term or condition, nor constitute nor be
deemed a waiver or release of any other rights, in law or at equity, or claims
that any party or any holder of Notes, Warrants, or Warrant Shares may have
against any other party or holder of Notes, Warrants, or Warrant Shares for
anything arising out of, connected with, or based upon this Agreement. No waiver
shall be enforceable against any person unless set forth in a written instrument
or agreement signed by that person. No waiver shall be deemed to occur as a
result of the failure of any party to enforce any term or condition of this
Agreement.

                                      -38-

     Re:  Sale of Reunion Industries Inc. ("Reunion") Common Stock
          --------------------------------------------------------

Gentlemen:

     Reference is made to the Amended and Restated Merger Agreement (the "Merger
Agreement") dated July 28, 1999, between Chatwins Group Inc. (the "Company") and
Reunion. Terms capitalized used but not defined herein shall have the meanings
given them in the Merger Agreement, a copy of which I have reviewed.

     I understand that for purposes of Rule 145 promulgated under the Securities
Act of 1933 (the "Securities Act"), I may be deemed to be an "affiliate" of the
Company in connection with the Merger.  I understand that because of my status
as an "affiliate" of the Company, any sale or disposition by me of any of the
Reunion Common Stock received by me as Merger Consideration may be made only in
accordance with the provisions of Rule 145 promulgated under the Securities Act
or pursuant to an effective registration statement under the Securities Act or
an exemption from registration.  I understand that the provisions of Rule 145(d)
restrict my sales of Reunion Common Stock during the period following the
Merger, and that, among other restrictions, pursuant to the Rule 145, such sales
may be made only in "brokers' transactions" and where the aggregate number of
shares sold by me, together with certain other persons affiliated with me,
during any three-month period does not exceed the greater of (i) 1% of the
Reunion Common Stock outstanding and (ii) the average weekly volume of trading
in Reunion Common Stock on the U.S. national securities exchanges.  I hereby
represent to you that I have consulted, and received advice from, my own legal
counsel relating to the applicable restrictions under the Securities Act.

     I will not sell or otherwise dispose of any of the Reunion Common Stock
received by me as a Merger Consideration except pursuant to the provisions of
Rule 145(d) or unless an effective registration statement under the Securities
Act is in effect for such sale or an exemption from such registration is
otherwise available under the Securities Act.  Further, I agree that any sale of
the Reunion Common Stock received by me as Merger
<PAGE>

Consideration will be limited to the amounts I could sell under Rule 144 of the
Securities Act had I received registered Common Stock in the Merger.

     I hereby represent to you that the shares of Reunion Common Stock I receive
as Merger Consideration are received for my own account, and that no other
person or entity had or has any beneficial interest in such securities, except
as set forth in the Proxy Statement/Prospectus heretofore filed by Reunion in
connection with the Merger or on Schedule 13D or 13G heretofore filed by the
undersigned.  Except as so set forth, I will take all such actions as may be
necessary, as promptly as practicable, to ensure that record ownership of said
shares of Reunion Common Stock received and held by me beneficially will be
owned of record by me.

     I acknowledge and agree that a legend will be placed on the said shares of
Reunion Common Stock to the following effect:

     "The Securities represented by this certificate are subject to certain
     restrictions under Rule 145 under the Securities Act of 1933, as amended
     (the "Act"), and may not be sold or otherwise transferred unless the
     securities subject to such sale or transfer are sold pursuant to Rule 145
     or are then the subject of an effective Registration Statement under the
     Act or unless an exemption from such registration is available."

     I understand and agree that the transfer agent for Reunion Common Stock,
acting with respect to the Reunion Common Stock registered in my name, will not
register any transfer(s) thereof except upon its receipt of an opinion of U.S.
counsel reasonably satisfactory to it, addressed to it and Reunion, to the
effect that the proposed transfer is in connection with a sale in accordance
with the terms of this Agreement.

                              Very truly yours,

                              ______________________________
                              Name:

Acknowledged and Agreed:
