                             POLYVISION CORPORATION

                                January 21, 2000

Item 2.  ACQUISITION OR DISPOSITION OF ASSETS

         (a) On January 21, 2000, pursuant to an Asset Purchase Agreement, dated
January 21, 2000, PolyVision Corporation (through its wholly-owned subsidiary,
Greensteel, Inc.) purchased substantially all of the assets of American
Chalkboard Company, L.L.C., an Alabama limited liability company ("American
Chalkboard"), and assumed certain of the liabilities of American Chalkboard, for
$5.25 million. The purchase price was determined as a result of arm's-length
negotiations between the parties.

                  In a separate transaction, on January 21, 2000, pursuant to an
Asset Purchase Agreement, dated January 21, 2000, PolyVision (through
Greensteel) purchased substantially all of the assets of Peninsular Slate
Company, a Michigan corporation, and Peninsular Slate Company of Texas, a Texas
corporation (together, "Peninsular Slate"), and assumed certain of the
liabilities of Peninsular Slate, for $4.2 million, subject to a working capital
adjustment. The purchase price was determined as a result of arm's-length
negotiations between the parties.

                  Both American Chalkboard and Peninsular Slate manufacture and
install chalkboards and other visual display boards primarily for the
educational products market. American Chalkboard maintains a production facility
in Wetumpka, Alabama, and Peninsular Slate maintains a production facility in
Troy, Michigan.

                  The acquisitions were funded by an increase in PolyVision's
senior secured credit facility.

                  Neither American Chalkboard nor Peninsular Slate had any
material relationship or association with PolyVision. The acquisitions will be
accounted for under the purchase method of accounting.

         (b) There are presently no significant changes anticipated in the
businesses or product lines of American Chalkboard or Peninsular Slate.

party shall notify the indemnifying party in writing within sixty (60) days of
the indemnified party's first receipt of notice of, or the indemnified party's
obtaining actual knowledge of, such claim, and in any event within such shorter
period as may be necessary for the indemnifying party or parties to take
appropriate action to resist such claim. Such notice shall specify all facts
known to the indemnified party giving rise to such indemnity rights and shall
estimate (to the extent reasonably possible) the amount of potential liability
arising therefrom. If the indemnifying party shall be duly notified of such
dispute, the parties shall attempt to settle and compromise the same or may
agree to submit the same to arbitration or, if unable or unwilling to do any of
the foregoing, such dispute shall be settled by appropriate litigation, and any
rights of indemnification established by reason of such settlement, compromise,
arbitration or litigation shall promptly thereafter be paid and satisfied by
those indemnifying parties obligated to make indemnification hereunder.

              12.4   RIGHT TO DEFEND. If the facts giving rise to any claim for
indemnification shall involve any actual or threatened action or demand by any
third party against the indemnified party or any of its affiliates, the
indemnifying party or parties shall be entitled (without prejudice to the
indemnified party's right to participate at its own expense through counsel of
its own choosing), at their expense and through a single counsel of their own
choosing, to defend or prosecute such claim in the name of the indemnifying
party or parties, or any of them, or if necessary, in the name of the
indemnified party. In any event, the indemnified party shall give the

and (ii) all unfilled sales orders from customers including, without limitation,
those set forth in Part II of SCHEDULE 4.15 (the "Sales Orders"); PROVIDED, that
nothing in this Agreement shall be construed as an assumption of any liabilities
or obligations of the Seller under any Purchase Order or Sales Order which, as a

of a third party which has not given such consent); and

                     (c) all performance bonds and other bonds of the Sellers
relating to the operations of the Business.

              2.2    DISCLAIMER OF LIABILITIES. Except for those specific

taxes, payroll taxes, withholding taxes, franchise taxes and other taxes,
including but not limited to any taxes which may arise out of or be assessable
in respect of the transactions contemplated by this Agreement, (c) claims,
litigation, liabilities or obligations (whether now pending or hereafter
asserted) arising out of or relating to the operations of the Sellers prior to
the Closing Date, (d) lease obligations of any kind, (e) liabilities or
obligations of any kind in respect of any past or present Stockholder,
directors, officers, employees or consultants of the Sellers, whether under any
contract or agreement, pursuant to any pension plan or employee benefit or
welfare plan, or otherwise, (f) liabilities or obligations for accrued employee
benefits and/or severance benefits in respect of any past or present employee of
the Sellers, or any ongoing obligations of the Sellers under any employment,
consulting or management agreement, (g) any obligations or liabilities in
respect of any unfunded pension or retirement benefits, or in respect of any
funding obligations to, or transactions in or relating to any trust funds under,
any pension, employee benefit or retirement plans now or heretofore maintained
by or on behalf of the Sellers for the benefit of any past or present employees,

remediation or any violation of any environmental laws or regulations, or any

<PAGE>


by the Sellers, (i) liabilities or obligations relating to recapture of any
depreciation deduction or investment tax credit of the Sellers, and/or (j) any
other liabilities or obligations of or relating to the Sellers in any manner
whatsoever.

         3.   PURCHASE PRICE.

              3.1    CONSIDERATION TO THE SELLERS. The purchase price for the
Assets, subject to Section 3.2 below (the "Consideration"), shall be equal to
Four Million Two Hundred Thousand Dollars ($4,200,000), which shall be payable
by (a) delivering to and depositing with Suntrust Bank, as Escrow Agent under
the Escrow Agreement (as defined in Section 7.3), on behalf of the Sellers, Two
Hundred Thousand Dollars ($200,000), and (b) paying to the Sellers, subject to
Section 3.2 below, the remaining Consideration in cash, by wire transfer of
immediately available funds to such account or accounts as shall be designated
by the Sellers reasonably in advance of the Closing Date.

              3.2    NET CONSIDERATION. To the extent that the Sellers have not
already paid their then existing bank or other secured debt out of its cash on
hand (other than trade payables and employee accruals incurred in the ordinary
course of business), the Buyer shall, on the Closing Date, apply a portion of
the Consideration payable pursuant to Section 3.1(b) above to the payment of the
Sellers' outstanding bank or other secured debt, so that such debt is paid in
full.

              3.3    WORKING CAPITAL ADJUSTMENT. On the Closing Date, the
Sellers will deliver to the Buyer a schedule and aging of the then-outstanding
accounts receivable ("Closing Date Receivables"), accounts payable ("Closing
Date Payables") and accruals to the extent not prorated and adjusted at the
Closing (the "Closing Date Accruals") of the Business. On a monthly basis
subsequent to the Closing Date, the Buyer will provide a reasonably detailed
accounting of all collections of Closing Date Receivables made during the
preceding month, and all payments made in respect of Closing Date Payables and
Closing Date Accruals during such preceding month; and, from and after such time
as the aggregate collections in respect of Closing Date Receivables equals the
aggregate amount of Closing Date Payables and Closing Date Accruals, any further
collections in respect of Closing Date Receivables shall be deposited by the
Buyer into a segregated interest-bearing account, and the balance of funds in
such segregated account will be paid over to the Sellers (to an account
designated by them) reasonably promptly after each month. All payments received
by the Buyer after the Closing Date that are from a customer who also owes
accounts receivable that are part of the Closing Date Receivables and are not
disputed shall be applied (i) first to such receivables (be they Closing Date
Receivables or other receivables) and in such amounts as designated by such
customer at time of payment, (ii) if some portion of the payment is not
designated to a specific receivable, then such portion shall be applied against
the Closing Date Receivables as apply to that customer, and (iii) if the payment
has no designation to specific receivables, the entire payment shall be applied
against the Closing Date Receivables as apply to that customer until such
Closing Date Receivables as apply to that customer are collected in full. On or
about that date which is 180 days after the Closing Date, the Buyer and the
Sellers will consult with one another in good faith to determine the appropriate
treatment of any uncollected or disputed


                                       5
<PAGE>


Closing Date Receivables (including any amounts representing contract
retainages), with a view to reaching final resolution on the aggregate
collectible amount of Closing Date Receivables and the correct aggregate amount
of Closing Date Payables and Closing Date Accruals. Any such reconciliation
and/or any payment made to the Sellers on the basis thereof shall be without
prejudice to the parties' rights in the event that actual collections or
liabilities are at variance with such reconciliation and/or payment. In the

contained in this Agreement, and subject only to any disclosure requirements
which may be imposed upon any party under applicable state or federal securities
or antitrust laws, it is expressly understood and agreed by the parties that,
except with respect to matters or information which are publicly available other
than by reason of a breach of this Section 7.1, (i) this Agreement, the
Schedules hereto, and the conversations, negotiations and transactions relating
hereto and/or contemplated hereby, and (ii) all financial information, business
records and other non-public information concerning either party which the other
party or its representatives has received or may hereafter receive, shall be
maintained in the strictest confidence by the recipient and its

<PAGE>


representatives, and shall not be disclosed to any person that is not associated
or affiliated with the recipient and involved in the transactions contemplated
hereby, without the prior written approval of the party which provided the

the transactions contemplated hereby shall not be consummated for any reason,
each party covenants and agrees that neither it nor any of its representatives
shall, except to the extent required in connection with any claims arising out
of the termination of this Agreement, retain (other than information which is
publicly available other than by reason of a breach of this Section 7.1) any
documents, lists or other writings of any other party which it may have received
or obtained in connection herewith or any documents incorporating any of the
information contained in any of the same (all of which, and all copies thereof
in the possession or control of the recipient or its representatives, shall be
returned to the party which provided the information).

              7.2    EXCLUSIVITY. From the date hereof through any termination
of this Agreement in accordance with Section 11 below, the Sellers and the
Stockholder shall not (and shall not permit any of their directors, officers or
affiliates to) negotiate with or enter into any other commitments, agreements or
understandings with any person, firm or corporation (other than the Buyer) in
respect of any sale of capital stock or assets of the Sellers, any merger,
consolidation or corporate reorganization, or any other such transaction
relating to the Sellers or the Business.

              7.3    COVENANT NOT TO COMPETE. The Sellers acknowledge that an

transactions contemplated hereby may be abandoned at any time prior to the
Closing: (a) by the mutual written consent of the Buyer, the Sellers and the

         12.  INDEMNIFICATION.

              12.1   GENERAL.

                     (a) Without prejudice to any rights of contribution as
between or among the Sellers and the Stockholder, the Sellers and the
Stockholder shall jointly and severally defend, indemnify and hold harmless the
Buyer from, against and in respect of any and all claims, losses, costs,
expenses, obligations, liabilities, damages, recoveries and deficiencies,
including interest, penalties and reasonable attorneys' fees, that the Buyer may
incur, sustain or suffer ("Losses") as a result of (i) any breach of, or failure
by the Sellers or the Stockholder to perform, any of the representations,
warranties, covenants or agreements of the Sellers or the Stockholder contained
in this Agreement or in any Schedule to this Agreement, and/or (ii) any failure
by the Sellers to pay or perform when due any of its retained liabilities.

                     (b) The Buyer shall defend, indemnify and hold harmless the
Sellers and the Stockholder from, against and in respect of any and all claims,
losses, costs, expenses, obligations, liabilities, damages, recoveries and
deficiencies, including interest, penalties and reasonable attorneys' fees, that
the Sellers or the Stockholder may incur, sustain or suffer as a result of (i)
any breach of, or failure by the Buyer to perform, any of the representations,
warranties, covenants or agreements of the Buyer contained in this Agreement,
and/or (ii) any failure by the Buyer to pay or perform when due any of the
Assumed Liabilities.

              12.2   LIMITATIONS ON CERTAIN INDEMNITY.

                     (a) Notwithstanding any other provision of this Agreement
to the contrary, neither the Sellers nor the Stockholder shall be liable to the
Buyer with respect to Losses unless and until the aggregate amount of all Losses
incurred by the Buyer shall exceed


                                       20
<PAGE>


the sum of $10,000 (the "Basket"); PROVIDED, HOWEVER, that the Basket shall not
be available with respect to any Losses under Section 12.1(a)(ii) above or any
Losses involving proven fraud by the Sellers or the Stockholder. The Sellers and
the Stockholder shall thereafter be jointly and severally liable for all Losses
in excess of the Basket, provided that the Sellers' and the Stockholder's
maximum aggregate liability in respect of all Losses shall not in any event
exceed the aggregate amount of $1,000,000 (the "Limitation"); PROVIDED, HOWEVER,
that the Limitation shall not be available with respect to any Losses under
Sections 4.7, 4.8, 4.12 and 4.14 or any Losses involving proven fraud by the
Sellers or the Stockholder. The Buyer shall, in respect of any such Losses, seek
recourse first against the Escrow Fund in accordance with the procedures set
forth in this Section 12 and the Escrow Agreement.

                     (b) The Buyer shall be entitled to indemnification by the
Sellers and the Stockholder for Losses only in respect of claims for which
notice of claim shall have been given to the Sellers or the Stockholder on or
before the second anniversary of the Closing Date.

              12.3   CLAIMS FOR INDEMNITY. Whenever a claim shall arise for
which any party shall be entitled to indemnification hereunder, the indemnified
party shall notify the indemnifying party in writing within sixty (60) days of
the indemnified party's first receipt of notice of, or the indemnified party's
obtaining actual knowledge of, such claim, and in any event within such shorter
period as may be necessary for the indemnifying party or parties to take
appropriate action to resist such claim. Such notice shall specify all facts
known to the indemnified party giving rise to such indemnity rights and shall
estimate (to the extent reasonably possible) the amount of potential liability
arising therefrom. If the indemnifying party shall be duly notified of such
dispute, the parties to this Agreement shall attempt to settle and compromise
the same or may agree to submit the same to arbitration or, if unable or
unwilling to do any of the foregoing, such dispute shall be settled by
appropriate litigation, and any rights of indemnification established by reason
of such settlement, compromise, arbitration or litigation shall promptly
thereafter be paid and satisfied by those indemnifying parties obligated to make
indemnification hereunder.

              12.4   RIGHT TO DEFEND. If the facts giving rise to any claim for
indemnification shall involve any actual or threatened action or demand by any
third party against the indemnified party or any of its affiliates, the
indemnifying party or parties shall be entitled (without prejudice to the
indemnified party's right to participate at its own expense through counsel of
its own choosing), at their expense and through a single counsel of their own
choosing, to defend or prosecute such claim in the name of the indemnifying
party or parties, or any of them, or if necessary, in the name of the
indemnified party. In any event, the indemnified party shall give the
indemnifying party advance written notice of any proposed compromise or
settlement of any such claim. If the remedy sought in any such action or demand
is solely money damages, the indemnifying party shall have fifteen (15) days
after receipt of such notice of settlement to object to the proposed compromise
or settlement, and if it does so object, the indemnifying party shall be
required to undertake, conduct and control, though counsel of its own choosing
and at its sole expense, the settlement or defense thereof, and the indemnified
party shall cooperate with the indemnifying party in connection therewith.

has all requisite corporate power and authority to execute and deliver this
Amendment No. 3, the New Term A Note, amendments to the Initial Security

all of which have been duly obtained, taken, given or made and are in full force
and effect, and except for filing UCC financing statements in additional
jurisdictions as occasioned by the Amendment No. 3 Acquisitions. All applicable
waiting periods in connection with the Amendment No. 3 Acquisitions have expired
without any action having been taken by any competent authority restraining,
preventing or imposing materially adverse conditions upon the Amendment No. 3
Acquisitions or the rights of the Loan Parties or their Subsidiaries freely to
transfer or otherwise dispose of, or to create any Lien on, any properties now
owned or hereafter acquired by any of them.

                  4.6 This Amendment No. 3, the New Term A Note and the other
New Documents have each been duly executed and delivered by each Loan Party that
is a party thereto and each of them and the Credit Agreement, as amended hereby,
constitutes the legal, valid and binding obligation of each Loan Party thereto,
enforceable against such Loan Party in accordance with its terms.

                  4.7 The Liens and security interests granted pursuant to the
Collateral Documents secure, without limitation, the indebtedness, liabilities
and obligations of the Borrowers to the Administrative Agent and the Lender
Parties under the Credit Agreement, as amended hereby, whether or not expressly
so stated in the Collateral Documents, and the terms "Obligations", "Debt" and
"Indebtedness" as used in such Collateral Documents (or any other term used
therein to describe or refer to the indebtedness, liabilities and obligations of
the Borrowers to the Administrative Agent and the Lender Parties) includes,
without limitation, the indebtedness, liabilities and obligations of the
Borrowers under the New Term A Note and the Credit Agreement as amended hereby.
Except for the filing of UCC financing statements in additional jurisdictions as
occasioned by the Amendment No. 3 Acquisitions, no new filings or recordings are
required in order to maintain the existing perfection or priority of the Liens
in favor of the Administrative Agent purportedly granted by the Collateral

any Loan Party or any of its respective Subsidiaries is a party has been duly
executed and delivered by such Loan Party or such Subsidiary, as the case may
be, and, to the best


<PAGE>

knowledge of the Borrowers, each Amendment No. 3 Acquisition Document has been
duly executed and delivered by the parties thereto other than the Borrowers and
their Subsidiaries, and is in full force and effect. The representations and
warranties of any Loan Party and each of its respective Subsidiaries contained
in each Amendment No. 3 Acquisition Document to which such Loan Party or such
Subsidiary, as the case may be, is a party are true and correct in all material
respects on the date hereof and will be true and correct in all material
respects on the Amendment No. 3 Effective Date and the date of consummation of
the Amendment No. 3 Acquisitions, as if made on each of such dates, and the
Administrative Agent and each Lender Party shall be entitled to rely upon such
representations and warranties with the same force and effect as if they were
incorporated in this Agreement and made to the Administrative Agent and each
Lender Party directly as of the date hereof, the Amendment No. 3 Effective Date,
and the date of consummation of the Amendment No. 3 Acquisitions.

                      (c) The execution and delivery by any Loan Party of each
of the Amendment No. 3 Acquisition Documents to which it is or will be a party
and the performance by each such Loan Party under each of the Amendment No. 3
Acquisition Documents to which it is or will be a party does not (i) violate any
law, rule or regulation (including, without limitation, the Williams Act,
Sections 13 and 14 of the Securities Exchange Act of 1934, and the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, and Regulations T, U, and
X of the Board of Governors of the Federal Reserve System and the rules and
regulations promulgated thereunder) or (ii) conflict with or result in a breach
of any order, writ, injunction, ordinance, resolution, decree, or other similar
document or instrument of any governmental entity, or any certificate of
incorporation or by-laws of or applicable to any Loan Party or create (with or
without the giving of notice or lapse of time, or both) a default under or
breach of or conflict with any agreement, instrument, ordinance, resolution,
decree, determination, award, bond, note, indenture, mortgage, deed of trust,
lease, writ, order or judgment to which it is a party or by which it is bound,
or any other agreement or instrument by which any of the properties or assets
owned by it or used in the conduct of its business is affected (other than any
agreement or other instrument of any kind the assets, revenues or liabilities in
respect of which do not exceed $100,000 individually or $250,000 in the
aggregate with respect to all of the foregoing and the breach thereof or
conflict therewith could not have a Material Adverse Effect on the Borrowers and
their Subsidiaries taken as a whole), or result in the imposition of any Lien of
any nature whatsoever upon any of the properties or assets owned by or used in
connection with the business of any Loan Party or any of its Subsidiaries,
except for the Liens created and granted or permitted under the Collateral
Documents or Credit Agreement, as amended and supplemented to date.

                      (d) Upon consummation of each of the Amendment No. 3
Acquisitions, each such Amendment No. 3 Acquisition shall have been consummated
pursuant to the terms and conditions of the applicable Amendment No. 3
Acquisition Documents and in compliance with all applicable laws, and ownership
of all of the Acquired Assets shall have vested in Greensteel free and clear of
all Liens, other than those created or permitted by the Collateral Documents or
the Credit Agreement, each as


<PAGE>

amended and supplemented to date. None of PolyVision or any of its Subsidiaries
which are parties to any of the Amendment No. 3 Acquisition Documents has waived
compliance by any of the other parties thereto with any term, covenant or
condition thereof, and no party thereto has breached any covenant set forth
therein or failed to perform any of its obligations thereunder which waiver,
breach or failure to perform is of a material term or condition or could
reasonably be expected to materially and adversely affect the Acquired Assets or
otherwise have a Material Adverse Effect.

                      (e) Each Amendment No. 3 Acquisition Document to which any
Loan Party or any of its respective Subsidiaries is or is to be a party has been
duly executed and delivered by such Loan Party or such Subsidiary, as the case
may be, and, to the best knowledge of the Borrowers, each Amendment No. 3
Acquisition Document has been duly executed and delivered by the parties thereto
other than the Borrowers and their Subsidiaries, and is in full force and
effect. The representations and warranties of any Loan Party and each of its
respective Subsidiaries contained in each Amendment No. 3 Acquisition Document
to which such Loan Party or such Subsidiary, as the case may be, is or is to be
a party are true and correct in all material respects on the date hereof, and
the Administrative Agent and each Lender Party shall be entitled to rely upon
such representations and warranties with the same force and effect as if they
were incorporated in this Agreement and made to the Administrative Agent and
each Lender Party directly as of the date hereof.

                      (f) True, correct and complete copies of each of the
Amendment No. 3 Acquisition Documents have been delivered to the Administrative
Agent, and as of the Amendment No. 3 Effective Date, each of the Amendment No. 3
Acquisitions shall have been consummated in accordance therewith, and no party
thereto shall have waived any material term or condition contained therein.

                      (g) Each Amendment No. 3 Acquisition Document to which any
Loan Party or American Chalkboard or Peninsular Slate is a party, when duly
executed and delivered by such Loan Party, American Chalkboard or Peninsular
Slate, as applicable, constitutes the valid and legally binding obligation of
each such Loan Party or (to the best knowledge of the Borrowers) American
Chalkboard and Peninsular Slate, as the case may be, enforceable in accordance
with its terms.

                      (h) No Borrower and none of Borrower's Subsidiaries is an
"investment company," or an "affiliated person" of, or "promoter" or "principal
underwriter" for, an "investment company," as such terms are defined in the
Investment Company Act of 1940, as amended. Neither the making of any Advances,
nor the issuance of any Letters of Credit, nor the application of the proceeds
or repayment thereof by the Borrowers, nor the consummation of any of the
transactions contemplated by this Amendment No. 3 or any Amendment No. 3
Acquisition Document will violate any provision of such Act or any rule,
regulation or order of the Securities and Exchange Commission thereunder or any
takeover, disclosure or other federal, state or foreign securities law or
Regulations T, U or X of the Federal Reserve Board. No Borrower is


<PAGE>

subject to regulation under any federal, state or foreign statute or regulation
which limits its ability to incur Debt.

assigns. The rights and obligations of the Borrowers under this Amendment No. 3
shall not be assigned or delegated without the prior written consent of the
Lender Parties, and any purported assignment or delegation without such consent
shall be void.

                                   ARTICLE V

         V.1 Each Guarantor hereby (i) acknowledges and consents to this
Amendment No. 2 (whether or not its consent is required); (ii) confirms and
agrees that its guaranty as set forth in Section 11 of the Note Agreement is,
and shall continue to be, in full force and effect and is hereby ratified and
confirmed in all respects, and all references in the Note Agreement shall mean
the Note Agreement as amended by this Amendment No. 2; and (iii) confirm and
agree that the obligations guaranteed by such Guarantor in such Section 11
include the obligations of the Company to the Holders under the Note Agreement
and the Notes as amended by this Amendment No. 2.

                                  ARTICLE VI

                    CONTINUED EFFECTIVENESS OF NOTE AGREEMENT

         Except as specifically amended herein, the Note Agreement and the other
Transaction Documents are, and shall remain, in full force and effect, and are
hereby ratified and confirmed in all respects except that on and after the
Amendment No. 2 Effective Date all references to the Note Agreement shall mean
the Note Agreement as amended and supplemented by this Amendment No. 2.

                                   ARTICLE VII

                                  MISCELLANEOUS

         VII.1 This Amendment No. 2 shall be governed by, and construed and
enforced in accordance with, the laws of the State of New York, without
regard to any conflicts of law rules which would require the application of
the laws of any other jurisdiction.

         VII.2 No modification or waiver of or with respect to any provisions
of this Amendment No. 2 or any other agreements, instruments and documents
delivered pursuant hereto nor consent by the Purchasers to any departure by
the Company or either Guarantor from any of the terms or

                                      -13-
<PAGE>

conditions thereof, shall in any event be effective unless it shall be in
writing and executed in accordance with the provisions of the Note Agreement,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. No consent to or demand on the Company or
either Guarantor in any case shall, of itself, entitle them to any other or
further notice or demand in similar or other circumstances. This Amendment No.
2, together with the Note Agreement, as so amended, and the other Transaction
Documents embodies the entire agreement and understanding among the Loan Parties
and the Purchasers, and supersedes all prior agreements and understandings,
relating to the subject matter hereof.

         VII.3 The provisions of this Amendment No. 2 are severable, and if
any clause or provision shall be held invalid or unenforceable in whole or in
part in any jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof, in such jurisdiction
and shall not in any manner affect such clause or provision in any other
jurisdiction, or any other clause or provision in this Amendment No. 2 in any
jurisdiction.

         VII.4 This Amendment No. 2 may be signed in any number of
counterparts with the same effect as if the signatures thereto and hereto
were upon the same instrument.

         VII.5 This Amendment No. 2 shall be binding upon and inure to the
benefit of the Loan Parties and their respective successors and to the
benefit of the Purchasers, any Holder and their respective successors and
assigns. The rights and obligations of the Loan Parties under this Amendment
No. 2 shall not be assigned or delegated without the prior written consent of
the Required Holders, and any purported assignment or delegation without such
consent shall be void.
