                SUPPLEMENT TO PROSPECTUS DATED MARCH 27, 1998 OF
      THE CERPLEX GROUP, INC. (FORMERLY KNOWN AS AURORA ELECTRONICS, INC.)
 
                            THE CERPLEX GROUP, INC.
                  (FORMERLY KNOWN AS AURORA ELECTRONICS, INC.)
 
                               RIGHTS TO PURCHASE
                                  32,976 UNITS
                               EACH CONSISTING OF
 $83.33 PRINCIPAL AMOUNT OF 10% SERIES B SENIOR SUBORDINATED NOTES DUE DECEMBER
                                  31, 2004 AND
 ONE SHARE OF 7% SENIOR CUMULATIVE CONVERTIBLE PREFERRED STOCK, PAR VALUE $.01
                                   PER SHARE
                     SUBSCRIPTION PRICE OF $183.33 PER UNIT
 
   
     The Effective Time of the Merger was 10:00 a.m., Pacific time, on April 30,
1998 and, accordingly, the Rights Offering also expired at such time. Prior to
the Effective Time, Aurora made certain amendments to the terms of the Aurora
Senior Subordinated Notes and the New Aurora Preferred Stock comprising each
Unit. As a result of such changes, Aurora is offering to the Public Stockholders
who subscribed for Units in the Rights Offering the opportunity to rescind their
subscriptions. Public Stockholders wishing to rescind their subscriptions must
do so in the manner described below.
    
 
     The changes to the terms of the Aurora Senior Subordinated Notes were made
to satisfy the requirements of Greyrock Business Credit, a division of
NationsCredit Commercial Corporation ("Greyrock"), the senior lender providing
the New Senior Loan, and the Trustee. The New Senior Loan provided by Greyrock
was required under the Merger Agreement and was a condition to the consummation
of the Merger and, as a consequence, the Rights Offering. The changes to the
terms of the New Aurora Preferred Stock were made in response to comments Aurora
received from the California Department of Corporations in connection with the
qualification of the Units for sale in the State of California.
 
     The following is a summary of the changes to the terms of the Aurora Senior
Subordinated Notes and the New Aurora Preferred Stock and is qualified in its
entirety by reference to the form of Indenture and the form of Aurora Senior
Subordinated Note attached thereto and the Certificate of Designations, amended
copies of which have been filed with the Registration Statement of which this
Prospectus Supplement is a part:
 
     (a) The subordination provisions of the Indenture and the Aurora Senior
Subordinated Notes have been amended:
 
          (i) to add to the term "Senior Indebtedness" any loans made to the
     Company as a debtor in possession in any bankruptcy proceeding by any
     persons who were the holders of any Senior Indebtedness on the date such
     bankruptcy proceeding was commenced;
 
          (ii) to redefine the term "Credit Agreement" to refer to the Loan and
     Security Agreement, dated as of April 30, 1998, among Aurora and certain of
     its affiliates as borrowers and Greyrock;
 
          (iii) to provide that notwithstanding any default or event of default
     with respect to the subordinated debt evidenced by the Aurora Senior
     Subordinated Notes, the holders of said Notes will take no action to
     accelerate or enforce said Notes or any rights or remedies relating thereto
     against Aurora until the expiration of six months after written notice of
     default is given by such holders to Greyrock;
 
          (iv) to expressly provide that obligations of the holders of the
     Aurora Senior Subordinated Notes under the subordination provisions of the
     Indenture shall continue to be effective, or be reinstated, as the case may
     be, if at any time any payment in respect of any Senior Indebtedness, or
     any other payment to any holder of any Senior Indebtedness in its capacity
     as such, is rescinded or must otherwise be restored or returned by the
     holder of such Senior Indebtedness upon the occurrence of any insolvency,
     bankruptcy, liquidation, reorganization or other similar proceedings, or
     any receivership proceedings in connection therewith, relative to Aurora or
     its creditors or its property or upon or as a result of the appoint of a
     receiver, intervenor or conservator of, or trustee or similar officer for,
     Aurora or any substantial part of its property or otherwise, all as though
     such payment had not been made;
 
          (v) to provide that Aurora shall not at any time offer (and the holder
     hereof shall not at any time accept) (A) any pledge of collateral or (B)
     any guaranty by any parent or subsidiary of Aurora, in each case with
     respect to the obligations of Aurora under the Aurora Senior Subordinated
     Notes.
<PAGE>   3
 
     (b) The prepayment provisions of the Indenture and the Aurora Senior
Subordinated Notes have been amended:
 
          (i) to provide that any notice of an optional or mandatory redemption
     of Aurora Senior Subordinated Notes (other than a redemption in connection
     with a holder's failure to consent to a waiver of any covenant, condition,
     default or Event of Default under the Indenture requested by Aurora) shall
     be delivered, (A) if from Aurora to the Trustee, not less than 45 days (as
     opposed to 30 days), and (B) if from the Trustee to the holders of Aurora
     Senior Subordinated Notes, not less than 30 days (as opposed to 20 days),
     prior to the scheduled redemption date;
 
   
          (ii) to provide that the date of a redemption shall (A) if required in
     connection with the existence of Excess Cash Flow in any fiscal year, be
     150 days (as opposed to 105 days), and (B) if required in connection with
     the consummation of any Sale or Issuance Transaction, be 50 days (as
     opposed to 5 days), after the end of such fiscal year; and
    
 
          (iii) to provide that if a mandatory redemption of the Aurora Senior
     Subordinated Notes shall be required, Aurora will deposit with the Trustee
     (at the same time Aurora provides notice of such redemption), an amount in
     immediately available funds sufficient to pay all outstanding principal and
     accrued interest through the scheduled redemption date on such Notes to be
     redeemed. Until disbursed by the Trustee, such funds shall be invested, for
     the account of Aurora, by the Trustee in certain permitted investments
     described in the Indenture.
 
     (c) The consent rights of the holders of New Aurora Preferred Stock have
been amended so that upon the consummation of a registered public offering of
Aurora Common Stock (other than on Form S-4 or S-8) for cash for the account of
Aurora, such consent rights will automatically terminate with respect to
Aurora's ability to (i) effect, validate or permit a Change of Control and (ii)
effect or validate the amendment, alteration or repeal of any provision of the
Aurora Charter or Aurora Bylaws.
 
   
     Subscriptions may be rescinded by completing and signing a Notice of
Rescission substantially in the form provided with this Prospectus Supplement
and forwarding such Notice of Rescission to the Subscription Agent. Public
Stockholders whose shares are held in the name of a bank or broker must contact
their bank or broker if they wish to rescind their subscriptions. Notices of
Rescission must be received by the Subscription Agent on or prior to May 29,
1998 (the "Rescission Expiration Date"). Any Notice of Rescission received by
the Subscription Agent after the Rescission Expiration Date will not be
accepted.
    
 
     Certificates representing the securities comprising the Units purchased
(and not rescinded), will be delivered to the purchasers thereof as soon as
practicable after the Rescission Expiration Date. It is expected that such
certificates will be available for delivery five business days following the
Rescission Expiration Date.
 
     Any questions or requests for assistance concerning the recission of a
subscription for Units should be directed to the Subscription Agent, American
Stock Transfer & Trust Company, at the following telephone number: (800)

                  (b) As long as any shares of Senior Preferred Stock shall

common stock of the Corporation, nor shall any shares of Junior Capital Stock be

any Junior Capital Stock, unless, in each such case, (i) full cumulative
dividends on the outstanding shares of Senior Preferred Stock shall have been
declared and paid and (ii) any arrears or defaults in any redemption of shares
of Senior Preferred Stock shall have been cured. The term "Junior Capital Stock"
as used herein means any shares of capital stock of the Corporation, including

the occurrence of certain events, (iii) any "person" or "group" will be deemed

                                       3
<PAGE>   4

shall be mailed, by first class or registered mail, postage prepaid, to each
holder of record of Senior Preferred Stock, at his, her or its address last
shown on the records of the transfer agent of the Senior Preferred Stock (or the
records of the Corporation, if it serves as its own transfer agent). The Senior
Preferred Redemption Notice shall set forth (i) the Senior Preferred Redemption
Date, (ii) the Senior Preferred Redemption Price, (iii) in the case of a
Mandatory Redemption, the total number of shares to be redeemed from all holders
and the number of shares to be redeemed from such holder, and (iv) in the case
of a Redemption at the Option of the Holder, a description of the events which
will, upon the occurrence thereof, constitute a Change of Control, including a
summary description of the terms thereof, and such holder's right to exercise
its option to require a redemption under paragraph 2(b) hereof. In the case of a
Mandatory Redemption, the Senior Preferred Redemption Notice shall call upon
such holder to surrender to the Corporation, in the manner and at the place
designated, his, her or its certificate or certificates representing any shares
of Senior Preferred Stock to be redeemed.

                  (d) Redeemed or Otherwise Acquired Shares to be Retired. On or
prior to a Senior Preferred Redemption Date, all holders of shares of Senior
Preferred Stock to be redeemed shall surrender their certificates representing
such shares to the Corporation, in the manner and at the place designated in the
Senior Preferred Redemption Notice, and against such surrender the Senior
Preferred Redemption Price of such shares shall be paid to the order of the
person whose name appears on each such certificate as the owner thereof. Each
surrendered certificate shall be canceled. From and after the Senior Preferred
Redemption Date, unless there shall have been a default in payment of the Senior
Preferred Redemption Price, all rights of the holders of the shares of redeemed
Senior Preferred Stock as holders of such shares of Senior Preferred Stock
(except the right to receive the Senior Preferred Redemption Price without
interest against surrender of their certificate or certificates) shall cease
with respect to such shares, and such shares shall not thereafter be transferred
on the books of the Corporation (or its transfer agent, if any) or be deemed to
be outstanding for any purpose whatsoever.

                  (e) Shares to be Redeemed or Purchased. If the funds of the
Corporation legally available for redemption of Senior Preferred Stock on any
Senior Preferred Redemption Date are insufficient, after redemption of any other
shares ranking senior thereto, to redeem the full number of shares of Senior
Preferred Stock to be redeemed on such date, those funds which are legally
available shall be used to redeem the maximum possible number of such shares of
Senior Preferred Stock ratably from each holder whose shares are otherwise
required to be redeemed. At any time 


                                       4
<PAGE>   5

thereafter when additional funds of the Corporation become legally available for
the redemption of Senior Preferred Stock, such funds will be used, at the end of
the next succeeding fiscal quarter, to redeem the balance of the shares which
the Corporation was theretofore obligated to redeem, ratably on the basis set
forth in the preceding sentence.

                  3. Liquidation, Dissolution or Winding Up. (a) In the event 
of any voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, the holders of shares of Senior Preferred Stock then outstanding
shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders, before any payment shall be made to the
holders of any shares of Junior Capital Stock by reason of their ownership
thereof, an amount equal to $100 per share of Senior Preferred Stock, plus all
accrued but unpaid dividends to which the holders of the Senior Preferred Stock
are then entitled pursuant to paragraph 1 above as of such date, and no more. If
upon any such liquidation, dissolution or winding up of the Corporation the
remaining assets of the Corporation available for distribution to its
stockholders (after making all distributions to which holders of capital stock
ranking senior to the Senior Preferred Stock shall be entitled) shall be
insufficient to pay the holders of shares of Senior Preferred Stock the full
amount to which they shall be entitled pursuant to this paragraph 3(a), the
holders of shares of Senior Preferred Stock, and any other shares ranking on a
parity therewith, shall share ratably in any distribution of the remaining
assets and funds of the Corporation in proportion to the respective amounts
which would otherwise be payable in respect of the shares of Senior Preferred
Stock held by them upon such distribution if all amounts payable on or with
respect to such shares were paid in full.

                  (b) After the payment of all amounts required to be paid
pursuant to paragraph 3(a) to the holders of shares of Senior Preferred Stock,
and any other shares ranking on a parity therewith, upon the dissolution,
liquidation or winding up of the Corporation, the holders of shares of Junior
Capital Stock then outstanding shall share in any distribution of the remaining
assets and funds of the Corporation in the manner provided by law, in the
Restated Certificate of Incorporation of the Corporation, as amended, or as
provided in any pertinent Certificate of Designations of the Corporation, as the
case may be.

                  (c) No Change of Control shall be deemed to be a liquidation,
dissolution or winding up of the Corporation for purposes of this paragraph 3.

                  4. Conversion. The shares of Senior Preferred Stock shall be
convertible as follows:


                                       5
<PAGE>   6

                  (a) Right to Convert. Subject to the terms and conditions of
this paragraph 4, the holder of any share or shares of Senior Preferred Stock
shall have the right, at his, her or its option, at any time, to convert any
such shares of Senior Preferred Stock (except that upon any liquidation of the
Corporation the right of conversion shall terminate as to all shares at the
close of business 15 days after notice thereof has been given to the holders of
Senior Preferred Stock as provided in paragraph 4(h) hereof) into such number of
fully paid and nonassessable whole shares of Common Stock as is obtained by (i)
multiplying the number of shares of Senior Preferred Stock so to be converted by
$100, (ii) adding the Additional Conversion Amount (as defined in paragraph 4(c)
herein), if any, and (iii) dividing the result by the conversion price of $0.25
or, if there has been an adjustment of the conversion price, by the conversion
price as last adjusted and in effect at the date any share or shares of Senior
Preferred Stock are surrendered for conversion (such price, or such price as
last adjusted, being referred to herein as the "Senior Preferred Conversion
Price"). Such right of conversion shall be exercised by the holder thereof by
giving written notice that the holder elects to convert a stated number of
shares of Senior Preferred Stock into Common Stock and by surrender of a
certificate or certificates for the shares so to be converted to the Corporation
at its principal office (or such other office or agency of the Corporation as
the Corporation may designate by notice in writing to the holder or holders of
the Senior Preferred Stock) at any time during its usual business hours on the
date set forth in such notice, together with a statement of the name or names
(with address), subject to compliance with applicable laws to the extent such
designation shall involve a transfer, in which the certificate or certificates
for shares of Common Stock shall be issued.

                  (b) Issuance of Certificates; Time Conversion Effected.
Promptly after the receipt by the Corporation of the written notice referred to
in paragraph 4(a) above and surrender of the certificate or certificates for the
share or shares of the Senior Preferred Stock to be converted, the Corporation
shall issue and deliver, or cause to be issued and delivered, to the holder,
registered in such name or names as such holder may direct, subject to
compliance with applicable laws to the extent such designation shall involve a
transfer, a certificate or certificates for the number of whole shares of Common
Stock issuable upon the conversion of such share or shares of Senior Preferred
Stock. To the extent permitted by law, such conversion shall be deemed to have
been effected and the Senior Preferred Conversion Price shall be determined as
of the close of business on the date on which such written notice shall have
been received by the Corporation and the certificate or certificates for such
share or shares shall have been surrendered as aforesaid, and at such time the
rights of the holder of such share or shares of Senior Pre-


                                       6
<PAGE>   7

ferred Stock shall cease, and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

                  (c) Fractional Shares; Dividends; Partial Conversion.

                  (i) No fractional shares shall be issued upon conversion of
         the Senior Preferred Stock into Common Stock and the number of shares
         of Common Stock to be issued shall be rounded to the nearest whole
         share. If any fractional interest in a share of Common Stock would,
         except for the provisions of this paragraph 4(c), be deliverable upon
         any such conversion, the Corporation, in lieu of delivering the
         fractional share thereof, shall pay to the holder surrendering the
         Senior Preferred Stock for conversion an amount in cash equal to the
         current fair market value of such fractional interest as determined in
         good faith by the Board of Directors of the Corporation.

                  (ii) Upon the conversion of any shares of Senior Preferred
         Stock, the Corporation will pay the holder thereof, out of funds
         legally available for such purpose, any accrued but unpaid dividends
         thereon to the date of such conversion. In the event that the
         Corporation is for any reason unable to pay some or all of such accrued
         but unpaid dividends, any amount not so paid shall (for purposes of
         paragraph 4(a) hereof) constitute the "Additional Conversion Amount."
         No other payment or adjustment shall be made upon any conversion on
         account of the Senior Preferred Stock so converted or the Common Stock
         issued upon such conversion.

                  (iii) In case the number of shares of Senior Preferred Stock
         represented by the certificate or certificates surrendered pursuant to
         paragraph 4(a) exceeds the number of shares converted, the Corporation
         shall, upon such conversion, execute and deliver to the holder thereof,
         at the expense of the Corporation, a new certificate or certificates
         for the number of shares of Senior Preferred Stock represented by the
         certificate or certificates surrendered which are not to be converted.

                  (d) Adjustment of Price Upon Issuance of Common Shares. Except
as provided in paragraph 4(e) hereof, if and whenever (after the date the shares
of Senior Preferred Stock shall have been issued and be outstanding) the
Corporation shall issue or sell, or is, in accordance with subparagraphs (d)(i)
through (d)(vii), deemed to have issued or sold, any shares of its Common Stock
without consideration or for a consideration per share less than the Senior
Preferred Conversion Price in effect 


                                       7
<PAGE>   8

immediately prior to the time of such issue or sale, then, forthwith upon such
issue or sale, the Senior Preferred Conversion Price shall be adjusted to the
price (calculated to the nearest cent) determined by dividing (x) an amount
equal to the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issue or sale (including as outstanding all shares of
Common Stock issuable upon conversion of outstanding Senior Preferred Stock or
upon conversion of outstanding Convertible Securities (as defined in
subparagraph (i) below)) multiplied by the then existing Senior Preferred
Conversion Price, and (B) the consideration, if any, received by the Corporation
upon such issue or sale, by (y) the total number of shares of Common Stock
outstanding immediately after such issue or sale (including as outstanding all
shares of Common Stock issuable upon conversion of outstanding Senior Preferred
Stock or outstanding Convertible Securities, in each case without giving effect
to any adjustment in the number of shares so issuable by reason of such issue
and sale).

                  No adjustment of the Senior Preferred Conversion Price,
however, shall be made in an amount less than $.01 per share, and any such
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which together with any adjustments
so carried forward shall amount to $.01 per share or more.

                  For purposes of this paragraph 4(d), the following
subparagraphs (i) through (vii) shall also be applicable:

                  (i) Issuance of Rights or Options. Subject to paragraph 4(e)
         hereof, in case at any time the Corporation shall in any manner grant
         (whether directly or by assumption in a merger or otherwise) any rights
         to subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock (other than shares of Senior Preferred Stock)
         or securities convertible into or exchangeable for Common Stock (such
         rights or options being herein called "Options" and such convertible or
         exchangeable stock or securities being herein called "Convertible
         Securities") whether or not such Options or the right to convert or
         exchange any such Convertible Securities are immediately exercisable,
         and the price per share for which Common Stock is issuable upon the
         exercise of such Options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (A) the total amount, if
         any, received or receivable by the Corporation as consideration for the
         granting of such Options, plus the minimum aggregate amount of
         additional consideration payable to the Corporation upon the exercise
         of all such Options, plus, in the case of such Options which relate to
         Convertible Securities, the minimum aggregate amount of additional
         consideration, if any, payable upon the issue or 


                                       8
<PAGE>   9

         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (B) the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such Options) shall be less than the Senior Preferred Conversion
         Price in effect immediately prior to the time of the granting of such
         Options, then the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon conversion or
         exchange of the total maximum amount of such Convertible Securities
         issuable upon the exercise of such Options shall be deemed to have been
         issued for such price per share as of the date of granting of such
         Options and thereafter shall be deemed to be outstanding. Except as
         otherwise provided in subparagraph (iii) below, no adjustment of the
         Senior Preferred Conversion Price shall be made upon the actual issue
         of such Common Stock or of such Convertible Securities upon exercise of
         such Options or upon the actual issue of such Common Stock upon
         conversion or exchange of such Convertible Securities.

                  (ii) Issuance of Convertible Securities. Subject to paragraph
         4(e) hereof, in case the Corporation shall in any manner issue (whether
         directly or by assumption in a merger or otherwise) or sell any
         Convertible Securities, whether or not the rights to exchange or
         convert thereunder are immediately exercisable, and the price per share
         for which Common Stock is issuable upon such conversion or exchange
         (determined by dividing (A) the total amount received or receivable by
         the Corporation as consideration for the issue or sale of such
         Convertible Securities, plus the minimum aggregate amount of additional
         consideration, if any, payable to the Corporation upon the conversion
         or exchange thereof, by (B) the total maximum number of shares of
         Common Stock issuable upon the conversion or exchange of all such
         Convertible Securities) shall be less than the Senior Preferred
         Conversion Price in effect immediately prior to the time of such issue
         or sale, then the total maximum number of shares of Common Stock
         issuable upon conversion or exchange of all such Convertible Securities
         shall be deemed to have been issued for such price per share as of the
         date of the issue or sale of such Convertible Securities and thereafter
         shall be deemed to be outstanding, provided that (x) except as
         otherwise provided in subparagraph (iii) below, no adjustment of the
         Senior Preferred Conversion Price shall be made upon the actual issue
         of such Common Stock upon conversion or exchange of such Convertible
         Securities, and (y) if any such issue or sale of such Convertible
         Securities is made upon exercise of any Option to purchase any such
         Convertible Securities for which adjustments of the Senior Preferred
         Conversion Price have been or are to be made pursuant to 


                                       9
<PAGE>   10

         other provisions of this paragraph 4(d), no further adjustment of the
         Senior Preferred Conversion Price shall be made by reason of such issue
         or sale.

                  (iii) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any Option referred to in subparagraph (i), the
         additional consideration, if any, payable upon the conversion or
         exchange of any Convertible Securities referred to in subparagraph (i)
         or (ii), or the rate at which any Convertible Securities referred to in
         subparagraph (i) or (ii) are convertible into or exchangeable for
         Common Stock shall change at any time (in each case other than under or
         by reason of provisions designed to protect against dilution), the
         Senior Preferred Conversion Price in effect at the time of such event
         shall forthwith be readjusted to the Senior Preferred Conversion Price
         which would have been in effect at such time had such Options or
         Convertible Securities still outstanding provided for such changed
         purchase price, additional consideration or conversion rate, as the
         case may be, at the time initially granted, issued or sold; and on the
         expiration of any such Option or the termination of any such right to
         convert or exchange such Convertible Securities, the Senior Preferred
         Conversion Price then in effect hereunder shall forthwith be increased
         to the Senior Preferred Conversion Price which would have been in
         effect at the time of such expiration or termination had such Option or
         Convertible Securities, to the extent outstanding immediately prior to
         such expiration or termination, never been issued, and the Common Stock
         issuable thereunder shall no longer be deemed to be outstanding. If the
         purchase price provided for in any such Option referred to in
         subparagraph (i) or the rate at which any Convertible Securities
         referred to in subparagraph (i) or (ii) are convertible into or
         exchangeable for Common Stock shall be reduced at any time under or by
         reason of provisions with respect thereto designed to protect against
         dilution, then, in case of the delivery of Common Stock upon the
         exercise of any such Option or upon conversion or exchange of any such
         Convertible Securities, the Senior Preferred Conversion Price then in
         effect hereunder shall forthwith be adjusted to such respective amount
         as would have been obtained had such Option or Convertible Securities
         never been issued as to such Common Stock and had adjustments been made
         upon the issuance of the shares of Common Stock delivered as aforesaid,
         but only if as a result of such adjustment the Senior Preferred
         Conversion Price then in effect hereunder is thereby reduced.

                  (iv) Stock Dividends. In case the Corporation shall declare a
         dividend or make any other distribution upon the 

                                       10

<PAGE>   11

         Common Stock of the Corporation payable in Common Stock, Options or
         Convertible Securities, the Senior Preferred Conversion Price shall be
         reduced as if the Corporation had subdivided its outstanding shares of
         Common Stock into a greater number of shares, as provided in
         subparagraph 4(d)(v) hereof.

                  (v) Subdivision or Combination of Stock. In case the
         Corporation shall at any time subdivide its outstanding shares of
         Common Stock into a greater number of shares, the Senior Preferred
         Conversion Price in effect immediately prior to such subdivision shall
         be proportionately reduced, and conversely, in case the outstanding
         shares of Common Stock of the Corporation shall be combined into a
         smaller number of shares, the Conversion Price in effect immediately
         prior to such combination shall be proportionately increased.

                  (vi) Consideration for Stock. In case any shares of Common
         Stock, Options or Convertible Securities shall be issued or sold for
         cash, the consideration received therefor shall be deemed to be the
         amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any shares of Common Stock, Options or Convertible Securities
         shall be issued or sold for a consideration other than cash, the amount
         of the consideration other than cash received by the Corporation shall
         be deemed to be the fair value of such consideration as determined in
         good faith by the Board of Directors of the Corporation, without
         deduction of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         The amount of consideration deemed to be received by the Corporation
         pursuant to the foregoing provisions of this subparagraph (vi) upon any
         issuance and/or sale of shares of Common Stock, Options or Convertible
         Securities, pursuant to an established compensation plan of the
         Corporation, to directors, officers or employees of the Corporation in
         connection with their employment shall be increased by the amount of
         any tax benefit realized by the Corporation as a result of such
         issuance and/or sale, the amount of such tax benefit being the amount
         by which the Federal and/or state income or other tax liability of the
         Corporation shall be reduced by reason of any deduction or credit in
         respect of such issuance and/or sale. In case any Options shall be
         issued in connection with the issue and sale of other securities of the
         Corporation, together comprising one integral transaction in which no
         specific consideration is allocated to such Options by the parties


                                       11
<PAGE>   12

         thereto, such Options shall be deemed to have been issued without
         consideration.

                  (vii) Record Date. In case the Corporation shall take a record
         of the holders of its Common Stock for the purpose of entitling them
         (A) to receive a dividend or other distribution payable in Common
         Stock, Options or Convertible Securities, or (B) to subscribe for or
         purchase Common Stock, Options or Convertible Securities, then such
         record date shall be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right of subscription or purchase,
         as the case may be.

                  (e) Certain Issues of Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not make any adjustment of the
Senior Preferred Conversion Price in the case of (i) the issuance of shares of
Common Stock upon conversion of Senior Preferred Stock; (ii) the issuance of
Options or shares of Common Stock to employees of the Corporation or its
subsidiaries, either directly or pursuant to Options, pursuant to plans or
arrangements approved by the Board of Directors of the Corporation; (iii) the
issuance of shares of Common Stock in respect of any Convertible Securities or
Options issued by the Corporation prior to the date of this Certificate of
Designations; (iv) the issuance of Common Stock or Options or Convertible
Securities as consideration in the acquisition by assumption or otherwise by the
Corporation of substantially all of the assets of any other entity or more than
50% of the voting power of any other entity, including by way of merger or
consolidation; or (v) the issuance of Options or Convertible Securities (or the
shares of Common Stock issuable upon conversion or exercise thereof) to banks or
other lenders as consideration for providing debt financing to the Corporation.

                  (f) Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation (a
"Reorganization") shall be effected in such a way (including, without
limitation, by way of consolidation or merger) that holders of Common Stock
shall be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a condition of such Reorganization, lawful
and adequate provision (in form satisfactory to the holders of a majority of the
then outstanding shares of Senior Preferred Stock) shall be made whereby each
holder of a share or shares of Senior Preferred Stock shall thereafter have the
right to receive, upon the basis and upon the terms and conditions specified
herein and in lieu of the shares of Common Stock of the Corporation immediately
theretofore receivable upon the conversion of such share or shares of the Senior
Preferred Stock, such shares 


                                       12
<PAGE>   13

of stock, securities or assets as may be issued or payable with respect to or in
exchange for a number of outstanding shares of such Common Stock equal to the
number of shares of such stock immediately theretofore so receivable had such
Reorganization not taken place, and in any such case appropriate provision shall
be made with respect to the rights and interests of such holder to the end that
the provisions hereof (including without limitation provisions for adjustments
of the Senior Preferred Conversion Price) shall thereafter be applicable, as
nearly as may be, in relation to any shares of stock, securities or assets
thereafter deliverable upon the exercise of such conversion rights (including an
immediate adjustment, by reason of such Reorganization, of the Senior Preferred
Conversion Price to the value for the Common Stock reflected by the terms of
such Reorganization if the value so reflected is less than the Senior Preferred
Conversion Price in effect immediately prior to such Reorganization). In the
event of a merger or consolidation of the Corporation as a result of which a
greater or lesser number of shares of common stock (or other equity interests,
of the case may be) of the surviving corporation or business entity are issuable
to holders of Common Stock of the Corporation outstanding immediately prior to
such merger or consolidation, the Senior Preferred Conversion Price in effect
immediately prior to such merger or consolidation shall be adjusted in the same
manner as though there were a subdivision or combination of the outstanding
shares of Common Stock of the Corporation. The Corporation will not effect any
Change of Control unless prior to the consummation thereof the acquiring
corporation or other business entity, or successor corporation or other business
entity (if other than the Corporation) resulting from such Change of Control, as
the case may be, shall assume by written instrument (in form reasonably
satisfactory to the holders of a majority of the shares of Senior Preferred
Stock at the time outstanding) executed and mailed or delivered to each holder
of a share or shares of Senior Preferred Stock at the last address of such
holder appearing on the books of the Corporation (or its transfer agent, if
any), the obligation to deliver to such holder such shares of stock, securities
or assets as, in accordance with the foregoing provisions, such holder may be
entitled to receive.

                  (g) Notice of Adjustment. Upon any adjustment of the Senior
Preferred Conversion Price, then and in each such case the Corporation shall
give written notice thereof, by first class mail, postage prepaid, addressed to
each holder of shares of Senior Preferred Stock at the address of such holder as
shown on the books of the Corporation (or its transfer agent, if any), which
notice shall state the Senior Preferred Conversion Price resulting from such
adjustment, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.

                  (h)   Other Notices. In case at any time:

                  (i) the Corporation shall declare any dividend upon its Common
         Stock payable in cash or stock or make any other distribution to the
         holders of its Common Stock;

                 (ii) the Corporation shall offer for subscription pro rata to
         the holders of its Common Stock any additional shares of stock of any
         class or other rights;

                (iii) there shall be any Reorganization or Change of Control
         or the Corporation shall become aware of any event or events that could
         reasonably be expected to result in a Reorganization or Change of
         Control; or

                 (iv) there shall be a voluntary or involuntary dissolution,
         liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, addressed to each holder of any shares of Senior
Preferred Stock at the address of such holder as shown on the books of the
Corporation (or its transfer agent, if any), (A) at least 15 days' prior written
notice of the date on which the books of the Corporation (or its transfer agent)
shall close or a record shall be taken for such dividend, distribution or
subscription rights or for determining rights to vote in respect of any such
Reorganization or Change of Control, and (B) in the case of any such
Reorganization or Change of Control, at least 15 days' prior written notice of
the date when the same shall take place. Such notice in accordance with the
foregoing clause (A) shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Stock shall be entitled thereto, and such notice in accordance with the
foregoing clause (B) shall also specify the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such Reorganization or Change of Control, as the case
may be.

   
                  (i) Conversion at Corporation's Option. All outstanding shares
of Senior Preferred Stock shall, on or after June 30, 1999, at the option of the
Corporation, be automatically converted into Common Stock if at any time (i) the
Corporation shall effect a firm commitment public offering of Common Stock or
Convertible Securities registered pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), resulting in proceeds to the Corporation and/or
selling stockholders of not less than $20,000,000, after deduction of
underwriting discounts and commissions but before deduction of other expenses of
issuance, and in which the offering price to the public (or, in the case of a
sale of Convertible Securities, the price per share of Common 
    


                                       14

Stock payable upon conversion thereof) is greater than the Senior Preferred
Conversion Price or (ii) the average closing sales price of Common Stock on one
or more national securities exchanges on which the Common Stock is listed or
quoted by NASDAQ or the OTC Bulletin Board over any period of twenty consecutive
trading days equals or exceeds 300% of the Senior Preferred Conversion Price and
the average daily trading volume for the Common Stock over such period equals or
exceeds 10,000,000 shares per week (as adjusted for stock splits, stock
dividends and other recapitalizations after the date of the first issuance of
Senior Preferred Stock). Such conversion shall be effected at the time of and
subject to the closing of the sale of such shares of Common Stock or on the
first trading day succeeding such trading period, as the case may be.

                  (j) Stock to be Reserved. The Corporation will at all times
reserve and keep available out of its authorized but unissued Common Stock,
solely for the purpose of issuance upon the conversion of the Senior Preferred
Stock as herein provided, such number of shares of Common Stock as shall then be
issuable upon the conversion of all outstanding shares of Senior Preferred
Stock. All shares of Common Stock which shall be so issued shall be duly and
validly issued and fully paid and nonassessable and free from all taxes, liens
and charges arising out of or by reason of the issue thereof, and, without
limiting the generality of the foregoing, the Corporation covenants that it will
from time to time take all such action as may be requisite to assure that the
par value per share of the Common Stock is at all times equal to or less than
the effective Senior Preferred Conversion Price. The Corporation will take all
such action within its control as may be necessary on its part to assure that
all such shares of Common Stock may be so issued without violation of any
applicable law or regulation, or of any requirements of any national securities
exchange upon which the Common Stock of the Corporation may be listed. The
Corporation will not take any action which results in any adjustment of the
Senior Preferred Conversion Price if after such action the total number of
shares of Common Stock issued and outstanding and thereafter issuable upon
exercise of all options and conversion of Convertible Securities, including upon
conversion of the Senior Preferred Stock, would exceed the total number of
shares of Common Stock then authorized by the Corporation's Restated Certificate
of Incorporation.

                  (k) No Reissuance of Senior Preferred Stock. Shares of Senior
Preferred Stock that are converted into shares of Common Stock as provided
herein shall not be reissued.

                  (l) Issue Tax. The issuance of certificates for shares of
Common Stock upon conversion of the Senior Preferred Stock shall be made without
charge to the holders thereof for any 


                                       15
<PAGE>   16

issuance tax in respect thereof, provided that the Corporation shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than that of the
holder of the Senior Preferred Stock which is being converted.

                  (m) Closing of Books. The Corporation will at no time close
its transfer books against the transfer of any Senior Preferred Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Senior Preferred Stock in any manner which interferes with the timely conversion
of such Senior Preferred Stock.

                  (n) Definition of Common Stock. As used in this paragraph 4,
the term "Common Stock" shall mean and include the Corporation's authorized
Common Stock, par value $.03 per share, as constituted on the date of filing of
this Certificate of Designations and shall also include any capital stock of any
class of the Corporation thereafter authorized that shall not be limited to a
fixed sum or percentage of par value in respect of the rights of the holders
thereof to participate in dividends or in the distribution of assets upon the
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation; provided, however, that such term, when used to describe the
securities receivable upon conversion of shares of the Senior Preferred Stock of
the Corporation, shall include only shares designated as Common Stock of the
Corporation on the date of filing of this Certificate of Designations, any
shares resulting from any combination or subdivision thereof referred to in
subparagraph (v) of paragraph 4(d), or in case of any reorganization or
reclassification of the outstanding shares thereof, the stock, securities or
assets provided for in paragraph 4(f).

                  5. Voting. Except as otherwise provided by law or in paragraph
6 below, the holders of Senior Preferred Stock shall vote together with the
holders of Common Stock on all matters to be voted on by the stockholders of the
Corporation, and each holder of Senior Preferred Stock shall be entitled to one
vote for each share of Common Stock that would be issuable to such holder upon
the conversion of all the shares of Senior Preferred Stock held by such holder
on the record date for the determination of stockholders entitled to vote.

                  6. Restrictions. So long as any shares of Senior Preferred
Stock are outstanding (except, with respect to clause (i) below, so long as at
least 25,000 shares of Senior Preferred Stock are outstanding), without the
consent of the holders of a majority of the Senior Preferred Stock at the time
outstanding given in person or by proxy, either in writing or at a special
meeting called for that purpose at which the holders of the Senior Preferred
Stock shall vote separately as a class, the 


                                       16

Corporation may not (i) effect, validate or permit a Change of Control; (ii)
effect or validate the amendment, alteration or repeal of any provision hereof
which would amend or repeal the dividend, voting, conversion, redemption or
liquidation rights of the Senior Preferred Stock set forth herein; (iii) effect
or validate the amendment, alteration or repeal of any provision of the Restated
Certificate of Incorporation or the By-laws of the Corporation; or (iv) (A)
create or authorize any additional class or series of stock ranking senior to or
on a parity with the Senior Preferred Stock as to dividends or as to rights upon
redemption, liquidation, dissolution or winding up, or (B) increase the
authorized number of shares of the Senior Preferred Stock or of any other class
or series of capital stock of the Corporation ranking senior to or on a parity
with the Senior Preferred Stock as to dividends or as to rights upon redemption,
liquidation, dissolution or winding up, whether any such creation or
authorization or increase shall be by means of amendment hereof, amendment of
the Restated Certificate of Incorporation of the Corporation, Certificate of
Designations or amendment thereof, merger, consolidation or otherwise; provided,
however, that the restrictions set forth in clauses (i) and (iii) above shall
automatically terminate and be of no force and effect at the time the
Corporation shall consummate a public offering of Common Stock for cash for the
account of the Corporation registered under the Securities Act on a Form other
than Form S-4 or S-8 (or successor forms).
    

                  7. Reacquired Shares. Any shares of Senior Preferred Stock,
which are redeemed or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof
and the number of authorized shares of Senior Preferred Stock shall be reduced
accordingly.

SECTION 2.02.    EXECUTION AND AUTHENTICATION

   
                 Two Officers shall sign the Notes for the Company by manual or

                 If an Officer whose signature is on a Note no longer holds

                 The Company shall enter into an appropriate agency agreement
with any Agent who is not a party to this Indenture.  The agreement shall
implement the provisions of this Indenture that relate to such Agent.  The
Company shall notify the Trustee of the name and address of any Agent not a
party to this Indenture.  If the Company fails to maintain a Registrar, Paying
Agent, or agent for service of notices and demands, or fails to give the
foregoing notice, the Trustee shall act as such.

                 The Company initially appoints the Trustee as Registrar,
Paying Agent, and agent for service of notices and demands. The Company may
remove any Agent upon written notice to such Agent and the Trustee; provided
that no such removal shall become effective until (i) the acceptance of an
appointment by a successor Agent to such Agent as evidenced by an appropriate
agency agreement entered into by the Company and such successor Agent and
delivered to the Trustee or (ii) notification to the Trustee that the Trustee
shall serve as such agent until the appointment of a successor Agent in
accordance with clause (i) of this proviso.

SECTION 2.04.    PAYING AGENT TO HOLD MONEY IN TRUST

                 On or prior to each due date of the principal of or interest
on any Notes, the Company shall deposit with the Paying Agent a sum sufficient
to pay such principal or interest so becoming due.  The Paying Agent shall hold
in trust for the benefit of Noteholders or the Trustee all money held by the
Paying Agent for the payment of principal of or interest on the Notes, and
shall notify the Trustee of any default by the Company (or any other obligor on
the Notes) in making any such payment.  If the Company or an Affiliate of the
Company acts as Paying Agent, it shall on or before each due date of the
principal of or interest on any Notes segregate the money and hold it as a
separate trust fund.  The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee and the Trustee may at any time during the
continuance of any default, upon written request to a Paying Agent, require
such Paying Agent to forthwith pay to the Trustee all sums so held in trust by
such Paying Agent.  Upon doing so, the Paying Agent (other than the Company)
shall have no further liability for the money.

SECTION 2.05.    NOTEHOLDER LISTS

   
                 The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Noteholders.  If the Trustee is not the Registrar, the Company
shall furnish to the Trustee at least seven days prior to each interest payment
date and at such other times as the Trustee may request in writing a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Noteholders.

SECTION 2.06.    TRANSFER AND EXCHANGE

                 When a Note is presented to the Registrar with a request to
register a transfer thereof, the Registrar shall register the transfer as
requested and when Notes are presented to the Registrar with a request to
exchange them for an equal principal amount of Notes of other authorized
denominations, the Registrar shall make the exchange as requested; provided
that every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar duly executed by
the Holder thereof or his attorney duly authorized in writing.  To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Notes at the Registrar's request.  Any exchange or
transfer shall be without charge, except that the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto, but this provision shall not apply to any exchange
pursuant to Section 2.10, 3.06 or 9.05.

SECTION 2.07.    REPLACEMENT NOTES

                 If a mutilated Note is surrendered to the Trustee, or if the
Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, and neither the Company nor the Trustee has received notice that such
Note has been acquired by a bona fide purchaser, the Company shall issue and
the Trustee shall authenticate a replacement Note if the requirements of
Section 8-405 of the New York Uniform Commercial Code, as in effect on the date
of this Indenture, are met, and there shall have been delivered to the Company
and the Trustee evidence to their satisfaction of the loss, destruction or
theft of any Note if such is the case.  An indemnity bond may be required that
is sufficient in the judgment of the Company and the Trustee to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Note is replaced.  The Company may charge for its expenses in replacing a
Note.  Every replacement Note is an additional obligation of the Company.

SECTION 2.08.    OUTSTANDING NOTES

                 Notes outstanding at any time are all Notes authenticated by
the Trustee, except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.08 as not outstanding.

                 If a Note is replaced pursuant to Section 2.07, it ceases to
be outstanding until the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.





                                       13
<PAGE>   21
                 If the Paying Agent (other than the Company or an Affiliate of
the Company) holds on a redemption date or maturity date money sufficient to
pay the principal of and accrued interest on Notes payable on that date, then
on and after that date such Notes cease to be outstanding and interest on them
ceases to accrue.

                 A Note does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Note.

SECTION 2.09.    CERTAIN NOTES DISREGARDED

                 In determining whether the Holders of the required principal
amount of Notes have concurred in any notice, direction, waiver or consent,
Notes owned by the Company or any other obligor on the Notes or by any
Affiliate of the Company or of such other obligor shall be disregarded, except
that for purposes of determining whether the Trustee shall be protected in
relying on any such notice, direction, waiver or consent, only Notes which the
Trustee knows are so owned shall be so disregarded.  Notes so owned which have
been pledged in good faith shall not be disregarded if the pledgee establishes
to the satisfaction of the Trustee the pledgee's right so to act with respect
to the Notes and that the pledgee is not the Company or any other obligor upon
the Notes or any Affiliate of the Company or of such other obligor.

SECTION 2.10.    TEMPORARY NOTES.

                 Until definitive Notes are ready for delivery, the Company may
prepare and, upon the order of the Company, the Trustee shall authenticate
temporary Notes.  Temporary Notes shall be substantially in the form of
definitive Notes but may have variations that the Company considers appropriate
for temporary Notes.  Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Notes in exchange for temporary
Notes.

SECTION 2.11.    CANCELLATION.

                 The Company at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for transfer, exchange, or payment.  The Trustee and
no one else shall cancel all Notes surrendered for transfer, exchange, payment
(including redemption), or cancellation and shall dispose of cancelled Notes as
the Company shall direct.  The Company may not issue new Notes to replace Notes
it has paid or delivered to the Trustee for cancellation.

SECTION 2.12.    DEFAULTED INTEREST.

                 If the Company defaults in a payment of interest on the Notes,
it shall pay the defaulted interest to the persons who are Note holders on a
subsequent special record date, and such term as used in this Section 2.12 with
respect to the payment of any defaulted interest, shall mean the fifteenth day
next preceding the special payment date fixed by the Company, whether or not
such day is a Business Day.  At least 15 days before the special record date,
the Company shall mail to each Noteholder and the Trustee a notice that states
the special record date, the special payment date and the amount of defaulted
interest to be paid.

Section 3.01(a) at any time, the Trustee shall select the Notes to be redeemed
from the outstanding Notes not previously called for redemption on a pro rata

after the end of each fiscal quarter (90 days after the end of the last fiscal
quarter of each year), an Officers' Certificate stating whether or not the

this Indenture and that the Company has complied with all conditions and
covenants under this Indenture. For purposes of this Section 4.03, such

requirement of notice provided under this Indenture. If any of the signers of

examination has included a review of the terms of this Indenture and the Notes
as they relate to accounting matters, (ii) that they have read the most recent

matters and, if any Default or Event of Default has come to their attention,
specifying the nature and period of existence thereof; provided that such
independent certified public accountants shall not be liable in respect of such
statement by reason of any failure to obtain knowledge of any such Default or
Event of Default that would not be disclosed in the course of an audit
examination conducted in accordance with generally accepted auditing standards
in effect at the date of such examination.

                The Company shall, so long as any of the Notes are outstanding,

         the failure of the Company or of any of its subsidiaries generally to
         pay its debts as such debts become due, or the taking of corporate
         action by the Company or any of its subsidiaries in furtherance of or
         which might reasonably be expected to result in any of the foregoing;
         or

                 (ix)     default or an event of default as defined in any
         instrument evidencing or under which the Company or any of its
         subsidiaries has outstanding at the time any Indebtedness in excess of
         $500,000 in aggregate principal amount shall occur and as a result
         thereof the maturity of any such Indebtedness shall have been
         accelerated so that the same shall have become due and payable prior
         to the date on which the same would otherwise have become due and
         payable and such acceleration shall not have been rescinded or
         annulled within 20 days; or

         days during which execution shall not be effectively stayed;


                 Subject to the provisions of Sections 7.01 and 7.02, the
Trustee shall not be charged with knowledge of any Event of Default unless
written notice thereof shall have been given to a Trust Officer at the
corporate trust office of the Trustee by the Company, the Paying Agent, any
Holder or an agent of any Holder.

SECTION 6.02.    ACCELERATION.

                 If an Event of Default (other than an Event of Default
specified in Section 6.01(vii) or (viii)) occurs and is continuing, the Trustee
may, by notice to the Company, or the Holders of at least 25% in principal
amount of the Notes then outstanding may, by notice to the Company and the
Trustee, and the Trustee shall, upon the request of such Holders, declare all
unpaid principal of and accrued interest to the date of acceleration on the
Notes then outstanding (if not then due and payable) to be due and payable and
upon any such declaration, the same shall become and be immediately due and
payable.  If an Event of Default specified in Section 6.01(vii) or (viii)
occurs, all unpaid principal and accrued interest on the Notes then outstanding
shall ipso facto become due and payable immediately without any declaration or
other act on the part of the Trustee or any Noteholder.

                 At any time after any declaration of acceleration has been
made as provided in this Section 6.02, and before a judgement or decree form
payment of money due has been obtained by the Trustee as hereinafter in this
Article provided, the holders of a majority in principal amount of the Notes
then outstanding may, by notice to the Company, rescind such declaration and
its consequences if

                 (1) the Company has paid or deposited with the Trustee a 
sum sufficient to pay

                          (A) all overdue interest on all Notes,

                          (B) the principal of (and premium, if any, on) any
                 Notes which have become due otherwise than by such declaration
                 of acceleration (including any Notes required to have been
                 purchased on the Purchase Date pursuant to an Offer to
                 Purchase made by the Company) and, to the extent that payment
                 of such interest is lawful, interest thereon at the rate
                 provided by the Notes,

                          (C) to the extent that payment of such interest is
                 lawful, interest upon overdue interest at the rate provided by
                 the Notes, and

                          (D) all sums paid or advanced by the Trustee
                 hereunder and the reasonable compensation, expenses,
                 disbursements and advances of the Trustee, its agents and
                 counsel;

         and





                                       28
<PAGE>   36
                 (2) all Events of Default, other than the non-payment of the
         principal of Notes which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 6.04.

No such rescission shall extend to or affect any subsequent default or Event of
Default or impair any right consequent thereon.

SECTION 6.03.    WAIVER OF TRIAL BY JURY; SUBMISSION TO JURISDICTION; OTHER 
                 REMEDIES.


                 The Company hereby waives any right to trial by jury in any 
legal proceeding related in any way to this Indenture or any Note and agrees
that any such proceeding may, if the Trustee or any Holder who is entitled to
bring such proceeding so elects, be brought and enforced in the Supreme Court of
the State of New York for New York County or the United States District Court
for the Southern District of New York and the Company hereby waives any
objection to jurisdiction or venue in any such proceeding commenced in such
court.  The Company further agrees that any process required to be served on it
for purposes of any such proceeding may be served on it, with the same effect as
personal service on it within the State of New York, by registered mail
addressed to it at its office or agency set forth in Section 11.02 for purposes
of notices hereunder.




                 If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect
the payment of the principal of or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

                 The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding.  A
delay or omission by the Trustee or any Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default.  No remedy
is exclusive of any other remedy.  All available remedies are cumulative to the
extent permitted by law.

SECTION 6.04.    WAIVER OF PAST DEFAULTS.



                 Subject to Sections 6.02, 6.07 and 9.02, the Holders of at
least a majority in aggregate principal amount of the outstanding Notes, by
notice to the Trustee, may waive an existing default or Event of Default and its
consequences, except a default in the payment of principal of, premium, if any,
or interest on any Note as specified in clause (i) or (ii) of Section 6.01 or in
respect of a covenant or provision of this Indenture which cannot be modified or
amended without the consent of the Holder of each outstanding Note affected.
Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereto.

SECTION 6.05.    WAIVER OF STAY, EXTENSION AND USURY DEFENSE.

                 The Company covenants (to the extent it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of, premium, if any, or interest on the
Notes as contemplated herein, wherever enacted, now or at any time hereafter





                                       29
<PAGE>   37
in force, or that may affect the covenants or the performance of this
Indenture; and (to the extent that it may lawfully do so) the Company hereby
expressly waives all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

SECTION 6.06.    CONTROL BY MAJORITY.

                 The Holders of at least a majority in aggregate principal
amount of the outstanding Notes, by notice to the Trustee, may direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee; provided that the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that may involve the Trustee in personal
liability, or that the Trustee determines in good faith may be unduly
prejudicial to the rights of Holders not joining in the giving of such
direction; and provided further that the Trustee may take any other action it
deems proper that is not inconsistent with any directions received from Holders
of Notes pursuant to this Section 6.06.

SECTION 6.07.    LIMITATION ON SUITS.

                 A Holder may not institute any proceeding, judicial or
otherwise, with respect to this Indenture or the Notes for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless: (i) such Holder
has previously given to the Trustee written notice of a continuing Event of
Default; (ii) the Holders of at least 25% in aggregate principal amount of
outstanding Notes shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder; (iii) such Holder or Holders have offered to the Trustee indemnity
reasonably satisfactory to the Trustee against any costs, liabilities or
expenses to be incurred in compliance with such request; (iv) the Trustee for 60
days after its receipt of such notice, request and offer of indemnity has failed
to institute any such proceeding; and (v) during such 60-day period, the Holders
of a majority in aggregate principal amount of the outstanding Notes have not
given the Trustee a direction that is inconsistent with such written request.
For purposes of Section 6.06 of this Indenture and this Section 6.07, the
Trustee shall comply with TIA Section 316(a) in making any determination of
whether the Holders of the required aggregate principal amount of outstanding
Notes have concurred in any request or direction of the Trustee to pursue any
remedy available to the Trustee or the Holders with respect to this Indenture or
the Notes or otherwise under the law.

            A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over such other Holder.

SECTION 6.08.    RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

                 Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of the principal of, premium,
if any, or interest on such Holder's Note on or after the respective due dates
expressed on such Note (including in a notice with respect to an Offer to
Purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

SECTION 6.09.    COLLECTION SUIT BY TRUSTEE.

                 If an Event of Default in the payment of principal or interest
specified in Section 6.01(i) or (ii) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any other obligor on the Notes for the whole amount of principal and
accrued interest remaining unpaid, together with interest on overdue principal
and, to the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate per annum borne by the Notes
and such further amount as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

SECTION 6.10.    TRUSTEE MAY FILE PROOFS OF CLAIM.

                 The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Noteholders allowed in any judicial proceedings relative to the Company (or any
other obligor on the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same, and any
Custodian in any such judicial proceeding is hereby authorized by each
Noteholder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07, and to
the extent that such payment for the reasonable compensation, expenses,
disbursements and advances in any such proceedings shall be denied for any
reason, payment of





                                       31
<PAGE>   39
the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property which the
Noteholders may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise.
Nothing herein contained shall be deemed to authorize the Trustee to authorize
or consent to or the Trustee to authorize or accept or adopt on behalf of any
Noteholder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceeding.

SECTION 6.11.    PRIORITIES.

                 Subject to Article 10, the Trustee collects any money pursuant
to this Article 6, it shall pay out the money in the following order:

                          First:  to the Trustee for amounts due under Section
                 7.07;

                          Second:  to Noteholders for amounts due and unpaid on
                 the Notes for principal and interest, ratably, without
                 preference or priority of any kind, according to the amounts
                 due and payable on the Notes for principal and interest,
                 respectively; and

                          Third:  to the Company.

          The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.11.

SECTION 6.12.    UNDERTAKING FOR COSTS.

                 In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defense made by the party
litigant. This Section 6.12 does not apply to a suit made by the Trustee, a
suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than
10% in principal amount of the Notes then outstanding.                   

SECTION 6.13.    RIGHTS AND REMEDIES CUMULATIVE.

                 Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or wrongfully taken Notes in Section
2.06, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is





                                       32
<PAGE>   40
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

SECTION 6.14.    DELAY OR OMISSION NOT WAIVER.

                 No delay or omission of the Trustee or of any Holder to
exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article Six or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

                                   ARTICLE 7

                                    TRUSTEE

SECTION 7.01.    DUTIES OF TRUSTEE.

                          (a)     If an Event of Default has occurred and is
                          continuing, the Trustee shall exercise such of the
                          rights and powers vested in it by this Indenture and
                          use the same degree of care and skill in their
                          exercise as a prudent person would exercise or use
                          under the circumstances in the conduct of his own
                          affairs.

                          (b)     Except during the continuance of an Event of
                          Default:

                                  (1) the Trustee need perform only those
                                  duties as are specifically set forth in this
                                  Indenture and no others; and

                                  (2) in the absence of bad faith on its part,
                                  the Trustee may conclusively rely, as to the
                                  truth of the statements and the correctness
                                  of the opinions expressed therein, upon
                                  certificates or opinions furnished to the
                                  Trustee and conforming to the requirements of
                                  this Indenture.  The Trustee, however, shall
                                  examine the certificates and opinions to
                                  determine whether or not they conform to the
                                  requirements of this Indenture.

<PAGE>   41
                                  (c)      The Trustee may not be relieved from
                                  liability for its own negligent action, its
                                  own negligent failure to act, or its own
                                  willful misconduct, except that:

                                        (1)  this paragraph does not limit the
                                           effect of paragraph (b) of this
                                           Section 7.01;

                                        (2)     the Trustee shall not be liable
                                           for any error of judgment made in
                                           good faith by a Trust Officer,
                                           unless it is proved that the Trustee
                                           was negligent in ascertaining the
                                           pertinent facts; and

                                        (3)     the Trustee shall not be liable
                                           with respect to any action it takes
                                           or omits to take in good faith in
                                           accordance with a direction received
                                           by it pursuant to Section 6.06.

   
                                  (d)      The Trustee may refuse to perform
                                  any duty or exercise any right or power under
                                  this Indenture unless it receives indemnity 
                                  satisfactory to it against any loss, 
                                  liability, expense or fee.
    

                                  (e)      Every provision of this Indenture
                                  that in any way relates to the Trustee is
                                  subject to paragraphs (a), (b), (c) and (d)
                                  of this Section 7.01.

                                  (f)      The Trustee shall not be liable for
                                  interest on any money received by it except
                                  as the Trustee may agree in writing with the
                                  Company.  Money held in trust by the Trustee
                                  need not be segregated from other funds
                                  except to the extent required by law.

   
                                  (g)      No provision of this Indenture shall 
                                  require the Trustee to expend or risk its own
                                  funds or incur any liability. The Trustee
                                  shall be under no obligation to exercise any
                                  of its rights and powers under this Indenture
                                  at the request of any Holder, unless such
                                  Holder shall have offered to the Trustee
                                  security and indemnity satisfactory to it
                                  against any loss, liability or expense.
    

SECTION 7.02.    RIGHTS OF TRUSTEE.

         Subject to Section 7.01:

   
                                  (a)      The Trustee may conclusively rely on
                                  any document believed by it to be genuine and
                                  to have been signed or presented by the proper
                                  person. The Trustee need not investigate any
                                  fact or matter stated in the document.
    

   
                                  (b)      Before the Trustee acts or refrains
                                  from acting, it may require an Officer's
                                  Certificate or an Opinion of Counsel, which
                                  shall conform to Section 11.03(b).  The
                                  Trustee shall not be liable
    





                                       34
<PAGE>   42
                                  for any action it takes or omits to take in
                                  good faith in reliance on such Certificate or
                                  Opinion.

                                  (c)      The Trustee may act through its
                                  agents and shall not be responsible for the
                                  misconduct or negligence of any agent
                                  appointed with due care.

                                  (d)      The Trustee shall not be liable for
                                  any action it takes or omits to take in good
                                  faith which it believes to be authorized or
                                  within its rights or powers.

                                  (e)      The Trustee may consult with counsel
                                  and the advice or opinion of such counsel as
                                  to matters of law shall be full and complete
                                  authorization and protection in respect of
                                  any action taken, omitted or suffered by it
                                  hereunder in good faith and in accordance
                                  with the advice or opinion of such counsel.

SECTION 7.03.    INDIVIDUAL RIGHTS OF TRUSTEE.

                 The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may otherwise deal with the Company or an
affiliate of the Company with the same rights it would have if it were not
Trustee.  Any Agent may do the same with like rights.  However, the Trustee is
subject to Sections 7.10 and 7.11.

SECTION 7.04.    TRUSTEE'S DISCLAIMER.

   
                 The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company's use of the proceeds from the Notes,
and it shall not be responsible for any statement in the Notes other than its
certificate of authentication.
    

SECTION 7.05.    NOTICE OF DEFAULTS OR EVENTS OF DEFAULT.

                 If a default or an Event of Default occurs and is continuing
and if it is known to the Trustee, the Trustee shall mail to each Noteholder
notice of the default or Event of Default within 90 days after it occurs.
Except in the case of a default or an Event of Default in payment of the
principal of or interest on any Note, the Trustee may withhold the notice if
and so long as a committee of its Trust Officers in good faith determines that
withholding the notice is in the interest of Noteholders.

SECTION 7.06.    REPORTS BY TRUSTEE TO HOLDERS.

                 Within 60 days after each [__________] beginning with the
[__________] following the date of this Indenture, the





                                       35
<PAGE>   43
Trustee shall mail to each Noteholder a brief report dated as of such
[__________] that complies with TIA Section 313(a).  The Trustee also shall
comply with TIA Section  313(b).

                 A copy of each report at the time of its mailing to
Noteholders shall be mailed to the Company and filed with the SEC and each
stock exchange, if any, on which the Notes are listed.  The Company shall
notify the Trustee whenever the securities become listed on any stock exchange.

SECTION 7.07.    COMPENSATION AND INDEMNITY.

                 The Company shall pay to the Trustee from time to time
reasonable compensation for its services (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of
an express trust).  The Company shall reimburse the Trustee upon request for
all reasonable disbursements, expenses and advances incurred or made by it.
Such expenses may include the reasonable compensation, disbursements and
expenses of Trustee's agents and counsel.

                 The Company shall indemnify the Trustee for, and hold it
harmless against, any loss, liability or expense incurred by it in connection
with its duties under this Indenture.  The Trustee shall notify the Company
promptly of any claim asserted against the Trustee for which it may seek
indemnity.  The Company shall defend the claim and the Trustee shall cooperate
in the defense.  The Trustee may have separate counsel and the Company shall
pay the reasonable fees and expenses of such counsel.  The Company need not pay
for any settlement made without its written consent.

   
                 The Company need not reimburse the Trustee for any expense or
indemnify it against any loss or liability incurred by it through its
negligence or willful misconduct.
    

                 To secure the Company's payment obligations in this Section,
the Trustee shall have a senior claim to which the Notes are hereby made
subordinate on all money or property held or collected by the Trustee, except
such money or property held in trust to pay the principal of and interest on
particular Notes.  The obligations of the Company under this Section 7.07 to
compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a lien prior to that
of the Notes upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the Holders of particular
Notes.  The obligation of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture.

                 When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(vii) and (viii) 





                                       36
<PAGE>   44


occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08.    REPLACEMENT OF TRUSTEE.

                 The Trustee may resign by so notifying the Company.  The
Holders of a majority in principal amount of the Notes then outstanding may
remove the Trustee by so notifying the Trustee and may appoint a successor
Trustee with the Company's written consent.  The Company may remove the Trustee
if:

                 (1)      the Trustee fails to comply with Section 7.10;

                 (2)      the Trustee is adjudged a bankrupt or an insolvent;

                 (3)      a receiver or other public officer takes charge of
                          the Trustee or its property; or

                 (4)      the Trustee becomes incapable of acting.

                 If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.

                 If a successor Trustee does not take office within 45 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of 10% in principal amount of the Notes then outstanding
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

                 If the Trustee fails to comply with Section 7.10, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee.

                 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after
that, the retiring Trustee shall transfer all property held by it as Trustee to
the successor Trustee, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers
and duties of the Trustee under this Indenture.  A successor Trustee shall mail
notice of its succession to each Noteholder.

                 Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 hereof shall
continue for the benefit of the retiring Trustee.

<PAGE>   45

SECTION 7.09.   SUCCESSOR TRUSTEE BY MERGER, ETC.

                 If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust assets to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee, provided such transferee
corporation shall qualify and be eligible under Section 7.10.

SECTION 7.10.    ELIGIBILITY; DISQUALIFICATION.

                 This Indenture shall always have a Trustee who satisfies the
requirements of paragraphs (1), (2) and (5) of TIA Section 310(a).  If at any
time the Trustee shall cease to satisfy any such requirements, it shall resign
immediately in the manner and with the effect specified in this Article 7.  The
Trustee shall comply with the provisions of TIA Section 310(b).  


SECTION 7.11.    PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                 The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b).  A trustee who has
resigned or been removed shall be comply with TIA Section 311(a) to the extent
indicated therein.


                                   ARTICLE 8

                    SATISFACTION AND DISCHARGE OF INDENTURE

SECTION 8.01.    TERMINATION OF COMPANY'S OBLIGATIONS.

                 If all Notes previously authenticated and delivered (other than
destroyed, lost or stolen Notes which have been replaced or paid or Notes for
whose payment money has theretofore been held in trust and thereafter repaid to
the Company, as provided in Section 8.03) have been delivered to the Trustee for
cancellation and the Company has paid all sums payable by it hereunder, then the
Company's obligations under the Notes and this Indenture shall be terminated.







                                       38
<PAGE>   46
                                  After such irrevocable deposit, the Trustee
upon request shall acknowledge in writing the discharge of the Company's
obligations under the Notes and this Indenture, except for those surviving
obligations specified above.

SECTION 8.02.    APPLICATION OF TRUST MONEY.

                 The Trustee or Paying Agent shall hold in trust, for the
benefit of the Holders, money deposited with it pursuant to Section 8.01, and
shall apply the deposited money in accordance with this Indenture to the payment
of the principal of and interest on the Notes.

SECTION 8.03.  REPAYMENT TO COMPANY.

                 Subject to Section 8.01, the Trustee and the Paying Agent
shall promptly pay to the Company upon request any excess money held by them
at any time.

                 The Trustee and the Paying Agent shall pay to the Company upon
request any money held by them for the payment of principal or interest that
remains unclaimed for two years after a right to such money has matured;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such payment, may at the expense of the Company cause to be
published once in a newspaper of general circulation in the City of New York or
mail to each Holder entitled to such money notice that such money remains
unclaimed and that after a date specified therein, which shall be at least 30
days from the date of such publication or mailing, any unclaimed balance of
such money then remaining will be repaid to the Company.  After payment to the
Company, Noteholders entitled to money must look to the Company for payment as
general creditors unless otherwise prohibited by law.

SECTION 8.04.    REINSTATEMENT.

                 If the Trustee or Paying Agent is unable to apply any money 
in accordance with Section 8.01 by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.01 until such time as the Trustee or
Paying Agent is







                                       39
<PAGE>   47
permitted to apply all such money; provided, however, that if the Company has
made any payment of the principal of or interest on any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive any such payment from the money held by
the Trustee or Paying Agent.

                                   ARTICLE 9

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.    WITHOUT CONSENT OF HOLDERS.

                 The Company and the Trustee may amend or supplement this
Indenture or the Notes without notice to or consent of any Noteholder:

                 (a)     to comply with Sections 4.04 and 5.01;

                 (b)     to provide for uncertificated Notes in addition to or 
                 in place of certificated Notes;

                 (c)     to cure any ambiguity, defect or
                 inconsistency, or to make any other change that does
                 not adversely affect the rights of any Noteholder; or
                 (d)     to comply with the provisions of the TIA, to the 
                 extent applicable.
SECTION 9.02.    WITH CONSENT OF HOLDERS.

                 Subject to Sections 6.04 and 6.07 and without prior notice to
the Holders, the Company, when authorized by its Board of Directors (as
evidenced by a Board Resolution), and the Trustee may amend this Indenture and
the Notes with the written consent of the Holders of not less than a majority in
principal amount of the Notes then outstanding, and the Holders of not less than
a majority in principal amount of the Notes then outstanding by written notice
to the Trustee may waive future compliance by the Company with any provision of
this Indenture or the Notes.

                 Notwithstanding the provisions of this Section 9.02, without
the consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not:

                 (i) change the stated maturity of the principal of, or any
installment of interest on, any Note;

                 (ii) reduce the principal amount of, or premium, if any, or
interest on, any Note;





                                       40
<PAGE>   48


            (iii) change the place or currency of payment of principal of, or 
premium, if any, or interest on, any Note;

            (iv) impair the right to institute suit for the enforcement of any
payment on a Note on or after the stated maturity thereof (or, in the case of a
redemption, on or after the redemption date) of any Note;

            (v) reduce the above-stated percentage of outstanding Notes the 
consent of whose Holders is necessary to modify or amend this Indenture;

            (vi) waive a default in the payment of principal of, premium, if
any, or interest on the Notes;

            (vii) reduce the percentage of aggregate principal amount of 
outstanding Notes the consent of whose Holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults; or

            (viii) modify any of the provisions of this Section 9.02, except to
increase any such percentage or to provide that certain other provisions of
this Indenture cannot be modified or waived without the consent of the Holder
of each outstanding Note affected thereby.

                 It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                 After an amendment, supplement or waiver under this Section
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver.  Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amendment, supplement or
waiver. 

SECTION 9.03.    INTEREST PAYMENT POSTPONEMENTS.

                 Holders of not less than 75% of the principal amount of the
Notes outstanding may consent on behalf of the Holders of all of the Notes to
the postponement of any or all payments of interest on the Notes for a period
of up to three years from the date or dates on which such interest payments are
due.

SECTION 9.04.    REVOCATION AND EFFECT OF CONSENT.

                 Until an amendment or waiver becomes effective, a consent to
it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Note or portion of a Note that evidences the same debt as the Note
of the consenting Holder, even if notation of the consent is not made on any
Note. However, any such Holder or subsequent Holder may revoke the consent as
to its Note or portion of its Note. Such revocation shall be effective only if
the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective. An amendment, supplement or waiver
shall become effective on receipt by the Trustee of written consents from the
Holders of



                                       41
<PAGE>   49
the requisite percentage in principal amount of the outstanding Notes.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver. If a record date is fixed, then,
notwithstanding the last two sentences of the immediately preceding paragraph,
those persons who were Holders at such record date (or their duly designated
proxies) and only those persons shall be entitled to consent to such amendment,
supplement or waiver or to revoke any consent previously given, whether or not
such persons continue to be Holders after such record date. No such consent
shall be valid or effective for more than 90 days after such record date.

            After an amendment, supplement or waiver becomes effective, it
shall bind every Holder unless it is of the type described in any of clauses
(i) through (v) of Section 9.02. In case of an amendment or waiver of the type
described in clauses (i) through (v) of Section 9.02, the amendment or waiver
shall bind each Holder who has consented to it and every subsequent Holder of a
Note that evidences the same indebtedness as the Note of the consenting Holder.

SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES.

            If an amendment, supplement or waiver changes the terms of a Note,
the Trustee may require the Holder to deliver the Note to the Trustee. The
Trustee may place an appropriate notation on the Note about the changed terms
and return it to the Holder and the Trustee may place an appropriate notation on
any Note thereafter authenticated.  Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation or issue a new Note shall not affect the validity and
effect of such amendment, supplement or waiver.

SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

            The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article Nine is
authorized or permitted by this Indenture. Subject to the preceding sentence,
the Trustee shall sign such amendment, supplement or waiver if the same does
not adversely affect the rights of the Trustee.  The Trustee may, but shall not
be obligated to, execute any such amendment, supplement or waiver that affects
the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

SECTION 9.07. CONFORMITY WITH TRUST INDENTURE ACT.

                 Every supplemental indenture executed pursuant to this Article
Nine shall conform to the requirements of the TIA as then in effect.

                                   ARTICLE 10


                             SUBORDINATION OF NOTES

SECTION 10.01.   NOTES SUBORDINATE TO SENIOR INDEBTEDNESS.

   
                 The Company covenants and agrees, and each holder of a Note,
by his or her acceptance thereof, likewise covenants and agrees, that, anything
contained in this Indenture to the contrary notwithstanding, the payment of the
principal of, premium, if any, and interest on, each and all of the Notes are
hereby expressly made subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness, to the extent hereinafter set
forth. Notwithstanding anything herein to the contrary (and without limiting
any of the other provisions hereof), notwithstanding any default or event of
default with respect to the subordinated debt evidenced by the Notes, the
holders of the Notes will take no action to accelerate or enforce the Notes or
any rights or remedies relating thereto against the Company (including without
limitation the commencement of, or joining in, any involuntary bankruptcy
petition or similar judicial proceeding against the Company) until the
expiration of six months after written notice of default is given by such
holders to the Senior Lender.
    


         (A)     In the event of any insolvency, bankruptcy, liquidation,
reorganization or other similar proceedings, or any receivership proceedings in
connection therewith, relative to the Company or its creditors or its property,
and in the event of any proceedings for voluntary liquidation, dissolution or
other winding up of the Company, whether or not involving insolvency or
bankruptcy proceedings, then all Senior Indebtedness shall first be paid in
full in cash and all obligations to provide financial accommodations under the
Credit Agreement have terminated, before any payment, whether on account of
principal, interest or otherwise, is made upon the Notes.

         (B)     In any of the proceedings referred to in paragraph (A) above,
any payment or distribution of any kind or character, whether in cash,
property, stock or obligations which may be payable or deliverable in respect
of the Notes shall be paid or delivered directly to the holders of Senior
Indebtedness for application in payment thereof, unless and until all Senior
Indebtedness shall have been paid in full in cash and all obligations to
provide financial accommodations under the Credit Agreement have terminated.

         (C)     No payment shall be made, directly or indirectly, on account
of the Notes (i) upon maturity of any Senior Indebtedness obligation, by lapse
of time, acceleration (unless waived), or otherwise, unless and until all
principal thereof and interest thereon and all other obligations in respect
thereof shall first have been paid in full in cash and all obligations to
provide financial accommodations under the Credit Agreement have terminated, or

for prepayment or by declaration or otherwise, unless and until such shall have
been cured or waived or shall have ceased to exist.

   
         (D)     Upon the happening of an event of default (other than described
in clause (A), (B), or (C) above) with respect to any Senior Indebtedness
permitting (after notice or lapse of time or both) one or more holders of such
Senior Indebtedness (or, in the case of the Credit Agreement, the Senior Lender)
to declare such Senior Indebtedness due and payable prior to the date on which
it is otherwise due and payable (a "Nonmonetary Default"), upon the (i) receipt
by the Trustee of a Blockage Notice, or (ii) if such Nonmonetary Default results
from the acceleration of the Notes, the date of such acceleration, then (x) the
Company will not make, directly or indirectly, to the holder of the Notes any
payment of any kind of or on account of all or any part of the Notes; (y)
neither the Trustee nor the Holders of the Notes will accept from the Company
any payment of any kind of or on account of all or any part of the Notes; and
(z) neither the Trustee nor the Holders of the Notes may take, demand, receive,
sue for, accelerate or commence any remedial proceedings with respect to any
amount payable under the Notes, unless and until in each case described in
clauses (x), (y) and (z), all such Senior Indebtedness shall have been paid in
full in cash and all obligations to provide financial accommodations under the
Credit Agreement have terminated; except, following the termination of a
Blockage Period, the Company will be permitted to make and the Trustee and the
Holders of the Notes will be permitted to accept payments in respect of the
indebtedness under the Notes if, as, when and to the extent that such payments
are made pursuant to the proviso to Section 14(a)(D) of the WCAS VII Notes, it
being understood that all such payments shall be made on a pro rata basis
between the Holders of the Notes and the holders of the WCAS VII Notes.
    

                 After payment in full of all amounts due or to become due on
all Senior Indebtedness, or provision is made for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, all payments or distributions shall be applied to the payment of
the principal and premium, if any, and accrued interest on the Notes and the
WCAS VII Notes, pro rata based on the aggregate principal amount of Notes and
the WCAS VII Notes then outstanding.

                 If any payment or distribution of any character or any
security, whether in cash, securities or other property, shall be received by
the Trustee or any Holder of Notes in contravention of any of the terms hereof
or before all the Senior Indebtedness obligations have been paid in full in cash
and all obligations to provide financial accommodations under the Credit
Agreement have terminated, and if the fact that such payment was in
contravention shall, at or prior to the time such payment is paid by the
Trustee to the Holders, have been made known to the Trustee, such payment or
distribution or security shall be received in trust for the benefit of, and
shall be paid over or delivered and transferred to, the holders of the Senior
Indebtedness at the time outstanding in accordance with the priorities then
existing





                                       44
<PAGE>   52
among such holders for application to the payment of all Senior Indebtedness
remaining unpaid, to the extent necessary to pay all such Senior Indebtedness
in full in cash.  In the event of the failure of any such Holder to endorse or
assign any such payment, distribution or security, each holder of any Senior
Indebtedness is hereby irrevocably authorized to endorse or assign the name.

   
                 The obligations of the Holders under this Article shall
continue to be effective, or be reinstated, as the case may be, if at any time
any payment in respect of any Senior Indebtedness, or any other payment to any
holder of any Senior Indebtedness in its capacity as such, is rescinded or must
otherwise be restored or returned by the holder of such Senior Indebtedness
upon the occurrence of any proceeding referred to in paragraph (A) above or
upon or as a result of the appoint of a receiver, intervenor or conservator of,
or trustee or similar officer for, the Company or any substantial part of its
property or otherwise, all as though such payment had not been made.
    

   
                 Notwithstanding anything to the contrary herein, the Company
shall not at any time offer (and the Holders shall not at any time accept) (i)
any pledge of collateral or (ii) any guaranty by any parent or subsidiary of the
Company, in each case with respect to the obligations of the Company under the
Notes.
    

SECTION 10.02.   PAYMENT PERMITTED IF NO DEFAULT.

                 Nothing contained in this Article or elsewhere in this
Indenture or in any of the Notes shall prevent (a) the Company, at any time
except during the pendency of any Proceeding referred to or under the conditions
described in Section in Section 10.01(A)-(D), from making payment on the Notes,
or (b) the applications by the Trustee of any money deposited with it hereunder
to Payments on the Notes or the retention of such Payments by the Holders, if,
at the time of such application by the Trustee, it did not have knowledge that
such Payments would have been prohibited by the provisions of this Article.

SECTION 10.03.   SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

                 Subject to the payment in full in cash of all Senior
Indebtedness as aforesaid and the termination of all obligations to provide
financial accommodations under the Credit Agreement, the Noteholders shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of any kind or character, whether in cash, property,
stock or obligations, which may be payable or deliverable to the holders of
Senior Indebtedness, until the principal of, and interest on, the Notes shall
be paid in full in cash, and, as between the Company, its creditors other than
the holders of Senior Indebtedness, and the Noteholders, no such payment or
distribution made to the holders of Senior Indebtedness by virtue of this
Article 10 which otherwise would have been made to the holder of the Notes
shall be deemed a payment by the Company on account of the Senior Indebtedness,
it being understood that the provisions of this Article 10 are and are intended
solely for the purposes of defining the relative rights of the Noteholders, on
the one hand, and the holder of the Senior Indebtedness, on the other hand.
Subject to the rights, if any, under this Article 10 of holders of Senior
Indebtedness to receive cash, property, stock or obligations otherwise payable
or deliverable to the Noteholders, nothing herein shall either impair, as
between the Company and the holder of the Notes, the obligation of the Company,
which is unconditional and absolute, to pay to the holder thereof the principal
thereof and interest thereon in accordance with its terms or prevent (except as
otherwise specified therein) the Noteholders from exercising all remedies
otherwise permitted by applicable law or hereunder upon default hereunder.

principal of (and premium, if any) and interest on the Notes as and when the
same shall become due and payable in accordance with their terms; or (b) affect
the relative rights against the Company of the Noteholders and creditors of the
Company other than the holders of Senior Indebtedness; or (c) prevent the

         Indebtedness or any other agreement which may be made relating to any
         Senior Indebtedness; or

                          (4)  any exercise or non-exercise by the holder of
         any Senior Indebtedness of any right, power, privilege or remedy under

         for the payment of such Senior Indebtedness; or

                          (5)  any merger or consolidation of the Company or

                          (7)  any other circumstance.

matters referred to in this Section 10.05; (ii) all notices which may be
required, whether by statute, rule of law or otherwise, to preserve intact any

SECTION 10.06.   NO WAIVER OF SUBORDINATION PROVISIONS.

                 No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                 Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Noteholders,

releasing the subordination provided in this Article or the obligations
hereunder of the Noteholders to the holders of Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment or

or all of the Senior Indebtedness; (iii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior

any fact known to the Company which would prohibit the making of any payment to
or by the Trustee in respect of the Notes.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not he
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Notes, unless and
until the Trustee shall have received written notice thereof from the Company or
a holder of Senior Indebtedness or from any trustee therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 7.01, shall be entitled in all respects to assume that no such facts
exist;

provided for in this Section at least two Business Days prior to the date upon
which by the terms hereof any money may become payable for any purpose

any) or interest on any Note), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purpose for which such money was received and
shall not be affected by any notice to the contrary which may be received by it
within two Business Days prior to such date.  Any notice required or permitted
to be given to the Trustee by a holder of Senior Indebtedness shall be in
writing and shall be sufficient for every purpose hereunder if in writing and

other facsimile number furnished in writing to such holder of Senior
Indebtedness by the Trustee, or (ii) mailed, first-class postage prepaid, or

be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee or
agent therefor) to establish that such notice has been given by a holder of
Senior Indebtedness (or a trustee or agent therefor).  In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness to participate in
any payment or distribution pursuant to this Article , the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Indebtedness held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution
and any other facts pertinent to the rights of such Person under this Article,
and if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent





                                       49

or other Person making such payment or distribution, delivered to the Trustee
or to the Holders of Notes, for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of the

or payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this Article.

                 The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and shall not be liable to any such holders
if it shall in good faith mistakenly pay over or distribute to Holders of Notes
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
or otherwise.

SECTION 10.11.   RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS;
                 PRESERVATION OF TRUSTEE'S RIGHTS.

                 The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

to, the Trustee under or pursuant to Section 7.07.

SECTION 10.12.   ARTICLE APPLICABLE TO PAYING AGENTS.
                 In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Company and be then acting hereunder, the term
"Trustee", as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; provided, however, that Section 10.12 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

amount hereof shall not be paid when due, whether at maturity or by acceleration
or otherwise, interest shall be paid at the rate of 12% per annum. Interest

that, if there is no existing default in the payment of interest, and if this
Note is authenticated between a record date referred to on the face hereof and

                  The Notes may be redeemed, at the Company's option, in whole
or in part at any time and from time to time at a redemption price equal to the
principal amount thereof, together with accrued interest to the date fixed for
redemption. In addition, the Company may redeem, at such redemption price, all
or any portion of the Notes of any Holder who has withheld its consent to the
waiver of any covenant, condition, default or Event of Default under the
Indenture requested by the Company.

6.       MANDATORY REDEMPTION

Issuance Transaction by the Company, the Company shall apply 100% of its
Available Cash Proceeds of such Sale or Issuance Transaction to the redemption

of less than all of the Notes and WCAS VII Notes then outstanding, such
redemption shall be made on a pro rata basis with respect to the Notes and the
WCAS VII Notes, based on the aggregate principal amount of Notes and the WCAS
VII Notes then outstanding.
    

                 Once notice of redemption has been made, Notes called for
redemption become due and payable on the redemption date and at the redemption
price.  Upon surrender of any Notes to the Paying Agent, such Notes shall be
paid at the redemption price, plus accrued and unpaid interest to the
redemption date.  In any event, failure to give notice, or any defect therein,

held by Holders to whom such notice was properly given.

7.       NOTICE OF REDEMPTION.

                  Notice of redemption shall be given in the manner provided in

multiple of $83.33 principal amount. On and after the Payment Date pursuant to

Notes surrendered for purchase by the Company, except for Notes which the
Company has failed to purchase and pay for.

                       CONSENT OF INDEPENDENT ACCOUNTANTS


The Board of Directors
The Cerplex Group, Inc.:

     Our report dated February 23, 1998, contains an explanatory paragraph that
states that the Company has suffered recurring losses from operations, has net
stockholders' and working capital deficiencies as well as insufficient funds to
pay its secured and unsecured debt obligations which raise substantial doubt
about its ability to continue as a going concern. The consolidated financial
statements and financial statement schedules do not include any adjustments
that might result from the outcome of this uncertainty.

     We consent to the use of our reports included herein and to the reference
to our firm under the heading "Experts" in the prospectus.

                                                       /s/ KPMG PEAT MARWICK LLP
