CUSIP No. 45767DAE9

                           Innova, S. de R.L. de C.V.

                      9.375% Senior Exchange Notes due 2013

     Innova,  S. de R.L. de C.V., a variable capital limited liability company
(sociedad de responsabilidad limitada de capital variable) organized under the
laws of the United Mexican States (hereinafter called the "Company", which term
includes any successor corporation under the Indenture referred to below), for
value received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of U.S. $[________]  (or such lesser amount as shall be the
outstanding principal amount of this Note shown in Schedule A hereto) on
September 19, 2013 and to pay interest thereon from September 19, 2003 or from
the most recent date to which interest has been paid or provided for,
semi-annually on March 19 and September 19 in each year (each, an "Interest
Payment Date"), commencing March 19, 2004 at the rate of 9.375% per annum, until
the principal hereof is paid or made available for payment. Interest on this
Note shall be calculated on the basis of a 360-day year consisting of twelve
30-day months.  The interest so payable and paid or provided for on any Interest
Payment Date will, as provided in such Indenture, be paid to the Person in whose
name this Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest, which shall be fifteen
calendar days preceding such Interest Payment Date. Any such interest which is
payable, but is not paid or provided for, on any Interest Payment Date shall
forthwith cease to be payable to the registered Holder hereof on the relevant
Regular Record Date by virtue of having been such Holder, and may be paid to the
Person in whose name this Note (or one or more Predecessor Notes) is registered
at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Company, notice whereof shall be given to
the Holders of Notes of this Series not less than 10 days prior to such Special
Record  Date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Notes
may be listed, and upon such notice as may be required by such exchange, all as
more fully provided in such Indenture.

     Payment of the principal of and the interest on this Note will be made at
the office or agency of the Company maintained for that purpose in The Borough
of Manhattan, The City of New York, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that, at the option of the Company,
interest may be paid by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register; provided,
further, that payment to DTC or any successor Depositary may be made by wire
transfer to the account designated by DTC or such successor Depositary in
writing.

     This Security is a global Note issued on the date hereof which represents
U.S$[________] of the principal amount of the Company's 9.375% Senior Exchange
Notes due 2013. This Note is one of a duly authorized issue of securities of the
Company (herein called the "Notes") issued and to be issued in one series under
an Indenture dated as of September 19, 2003 (herein called the "Indenture")
between the Company and The Bank of New York, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities  thereunder of the Company, the Trustee and the Holders of the Notes,
and of the terms  upon  which the Notes are, and are to be, authenticated and
delivered.  This  Note  is one of the  series  designated  on the  face  hereof,
initially  limited  (subject to  exceptions  provided in the  Indenture)  to the
aggregate principal amount specified in the Indenture.
<PAGE>

     If an Event of  Default  with  respect  to the  Notes  shall  occur  and be
continuing,  the  principal  of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
amendment  thereof and the  modification  of the rights and  obligations  of the
Company and the rights of the Holders of the Notes issued under the Indenture at
any time by the Company  and the Trustee  with the consent of the Holders of not
less than a majority in aggregate principal amount of the Securities at the time
Outstanding  of each  series  affected  thereby.  The  Indenture  also  contains
provisions   permitting  the  Holders  of  specified  percentages  in  aggregate
principal  amount of the Notes  Outstanding,  on  behalf of the  Holders  of all
Notes,  to waive  compliance  by the  Company  with  certain  provisions  of the
Indenture and certain past defaults under the Indenture and their  consequences.
Any such  consent or waiver by the Holder of this Note shall be  conclusive  and
binding  upon such  Holder and upon all  future  Holders of this Note and of any
Notes issued upon the  registration of transfer hereof or in exchange herefor or
in lieu  hereof,  whether or not notation of such consent or waiver is made upon
this Note or such Notes.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  shall alter or impair the  obligation  of the Company,  which is
absolute and  unconditional,  to pay the principal of and interest on this Note,
at the times,  place and rate,  and in the coin or  currency,  herein and in the
Indenture prescribed.

     As provided in the Indenture and subject to certain  limitations  set forth
therein and in this Note,  the  transfer of this Note may be  registered  on the
Security  Register upon surrender of this Note for  registration  of transfer at
the  office or agency of the  Company  maintained  for the  purpose in any place
where the principal of and interest on this Note are payable,  duly endorsed by,
or accompanied by a written  instrument of transfer in form  satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or by his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Notes are issuable in book-entry  fully registered form without coupons
in minimum  denominations of U.S.$1,000 and integral  multiples of U.S.$1,000 in
excess  thereof as more fully  provided  in the  Indenture.  As  provided in the
Indenture,  and subject to certain limitations set forth in the Indenture and in
this Note, the Notes are exchangeable  for a like aggregate  principal amount of
Notes of this Series in different authorized denominations,  as requested by the
Holders surrendering the same.

     No service  charge shall be made for any such  registration  of transfer or
exchange,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith,  other than in
certain cases provided in the Indenture.

     Prior to due  presentment of this Note for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose  name  this  Note is  registered  as the  owner  hereof  for all
purposes,  whether or not this Note be overdue,  and neither  the  Company,  the
Trustee nor any such agent shall be affected by notice to the contrary.

from its obligations  with respect to the Notes (subject to certain  exceptions)
or (ii)  the  Company  may be  released  from  its  obligation  under  specified
covenants  and  agreements  in the  Indenture,  in  each  case  if  the  Company
irrevocably  deposits  with the  Trustee  money or U.S.  Government  Obligations
sufficient  to pay and discharge  the entire  indebtedness  on all Notes of this
series,  and satisfies certain other  conditions,  all as more fully provided in
the Indenture.

     This Security is one of a duly authorized issue of Notes of the Company
designated as its 9.375% Senior Exchange Notes due 2013 (hereinafter called the
"Notes"), limited in aggregate principal amount to U.S.$ [_______], issued and
to be issued under an Indenture, dated as of September 19, 2003 (hereinafter
called the "Indenture"), among the Company, The Bank of New York, as Trustee,

(Luxembourg), as Luxembourg Paying Agent and Transfer Agent.

     ADDITIONAL AMOUNTS. The Company will pay to the Holders of the Notes such
Additional Amounts as may become payable under Section 4.21 of the Indenture.

     REPURCHASE OF NOTES UPON A CHANGE OF CONTROL. The Company must commence,
within 30 days of the occurrence of a Change of Control, and consummate an Offer
to Purchase for all Notes then Outstanding, at a purchase price equal to 101% of
the principal amount of the Notes plus accrued interest (if any) to the Payment
Date.  The Company is not required to make an Offer to Purchase following a
Change of Control if a third party makes an Offer to Purchase that would be in
compliance with the provisions described in this section if it were made by the
Company and such third party purchases (for the consideration referred to in the
immediately preceding sentence) the Notes validly tendered and not withdrawn.
Prior to the mailing of the notice to Holders commencing such Offer to Purchase,
but in any event within 30 days following any Change of Control, the Company
covenants to (i) repay in full all indebtedness of the Company that would
prohibit the repurchase of the Notes pursuant to such Offer to Purchase or (ii)
obtain any requisite consents under instruments governing any such indebtedness
of the Company to permit the repurchase of the Notes.  The Company shall first
comply with the covenant in the preceding sentence before it shall be required
to repurchase Notes pursuant to this "Repurchase of Notes upon a Change of
Control" covenant.

     WITHHOLDING TAX REDEMPTION. The Notes will be subject to redemption in
whole, but not in part, at the option of the Company at any time at 100% of
their principal amount, together with accrued interest thereon, if any, to the
Redemption Date, in the event the Company has become or would become obligated
to pay, on the next date on which any amount would be payable with respect to
such Notes, any Additional Amounts in excess of those attributable to a
withholding tax rate of 10% as a result of a change in or amendment to the laws
(including any regulations, rules or rulings promulgated thereunder) of Mexico
(or any political subdivision or taxing authority thereof or therein), or any
change in or amendment to any official position regarding the application,
administration or interpretation of such laws, rules, regulations or rulings,
including a holding of a court of competent jurisdiction, which change or
amendment is announced or becomes effective on or after the Closing Date.

     NOTICE OF REDEMPTION. Notice of redemption shall be given by the Company to
the Trustee and each Holder whose Notes are to be redeemed in accordance with
the provisions of Sections 3.02 and 3.04, respectively, of the Indenture.

     If notice of redemption has been given in the manner provided above, the
Notes specified in such notice to be redeemed shall become due and payable on
the Redemption Date at the Redemption Price stated therein, together with
accrued interest to such Redemption Date, and on and after such date (unless the
Company shall default in the payment of such Notes at the Redemption Price and
accrued interest to the Redemption  Date, in which case the principal, until
paid, shall bear interest from the Redemption Date at the rate prescribed in the
Notes), such Notes shall cease to accrue interest. Upon surrender of any Note
for redemption in accordance with a notice of redemption, such Note shall be
paid and redeemed by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided that installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders registered as such at the close of business on the relevant Regular
Record Date.

     All terms used in this Note which are defined in the  Indenture  shall have
the meanings assigned to them in the Indenture.

THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY AND BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
