TO THE HOLDERS OF SHARES OF COMMON STOCK, PAR VALUE $.02 PER SHARE, AND THE
HOLDERS OF SERIES 1995 8% CONVERTIBLE PREFERRED STOCK, OF TESCORP, INC.:
 
                                  INTRODUCTION
 
    Tescorp Acquisition Corporation (the "Purchaser"), a Delaware corporation
and a wholly owned subsidiary of Supercanal Holding S.A. ("Parent"), an
Argentine corporation, hereby offers to purchase (i) all the outstanding shares
of common stock, par value $0.02 per share ("Common Shares"), of Tescorp, Inc.
(the "Company"), a Texas corporation, for $4.50 per Common Share, net to the
seller in cash, and (ii) all the outstanding shares of Series 1995 8%
Convertible Preferred Stock ("8% Preferred Shares") of the Company for $144 per
share plus accrued dividends from the last date on which dividends were paid to
the Expiration Time (as defined below) (collectively the Common Shares and the
8% Preferred Shares are referred to as the "Shares" and the $4.50 per share
price and the $144 per share price plus accrued dividends which the Purchaser is
offering to pay are referred to as the "purchase prices"), upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the related
Letters of Transmittal (which together, as amended from time to time, constitute
the "Offer").
 
    The Offer is being made in accordance with an Amended Stock Purchase and
Merger Agreement (the "Merger Agreement") dated as of November 26, 1997 between
the Purchaser and the Company. The Merger Agreement contemplates that (i) the
Purchaser would purchase from the Company 6,006,006 Common Shares for $3.33 per
share (the "Stock Purchase"), (ii) not later than December 5, 1997, the Company
would announce the Offer and (iii) if the Purchaser purchases at least a number
of Common Shares and 8% Preferred Shares which, together with the shares already
owned by the Purchaser (which will include the 6,006,006 Common Shares purchased
by the Purchaser in the Stock Purchase), constitutes at least two thirds of the
outstanding Common Shares and two-thirds of the outstanding 8% Preferred Shares,
and the other conditions set forth in the Merger Agreement are satisfied or
waived, the Purchaser will take all steps in its power to cause the Purchaser to
be merged into the Company in a transaction in which Supercanal Holding S.A.,
the sole stockholder of the Purchaser, will become the sole stockholder of the
corporation which survives the Merger and all the stockholders of the Company
other than the Purchaser will receive cash in the same amount per Common Share
and per 8% Preferred Share as is paid for Shares purchased through the Offer.
Under the Merger Agreement, if a tender offer is commenced by someone other than
the Purchaser for all the outstanding Common Shares and 8% Preferred Shares
which the Company's Board of Directors determines to be superior to the Offer
and which the Board of Directors resolves to accept or to recommend to the
Company's stockholders, the Company may terminate the Merger Agreement by paying
the Purchaser $5 million.
 
    Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes as a result of the sale of shares to the
Purchaser in response to the Offer.
 
    Any tendering stockholder who fails to complete and sign the Substitute Form
W-9 included in the Letter of Transmittal may be subject to a required backup
Federal income tax withholding of 31% of the gross proceeds payable to the
stockholder or other payee pursuant to the Offer. See Section 3. The Purchaser
will pay all charges and expenses of Furman Selz LLC and ING Baring (U.S.)
Securities, Inc. as Dealer Managers (the "Dealer Managers"), The Bank of New
York, as Depositary (the "Depositary"), and Morrow & Co., Inc., as Information
Agent (the "Information Agent"), incurred in connection with the Offer. See
Section 17.
 
    THE BOARD OF DIRECTORS OF THE COMPANY (1) HAS APPROVED THE OFFER AND THE
MERGER WHICH WILL FOLLOW THE OFFER IF THE OFFER IS SUCCESSFULLY COMPLETED AND
THE SHAREHOLDERS OF THE COMPANY APPROVE THE MERGER, (2) HAS DETERMINED THAT THE
TERMS OF THE OFFER AND THE MERGER EACH IS FAIR TO AND IN THE BEST INTERESTS OF
THE COMPANY'S STOCKHOLDERS, AND (3) RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS
ACCEPT THE OFFER AND TENDER THEIR SHARES IN RESPONSE TO THE OFFER.
<PAGE>
    THE MINIMUM CONDITION.  The Offer is subject to a number of conditions,
including the Minimum Condition. See Section 15. The Minimum Condition requires
that (i) the number of Common Shares tendered and not withdrawn before the
Expiration Time, when added to the number of Common Shares already owned by the
Purchaser, constitute more than two-thirds of the total number of outstanding
Common Shares and (ii) the number of 8% Preferred Shares validly tendered and
not withdrawn before the Expiration Time, when added to the number of 8%
Preferred Shares already owned by the Purchaser, constitute more than two-thirds
of the total number of outstanding 8% Preferred Shares. The Company has informed
the Purchaser that as of December 5, 1997, there were 19,223,456 outstanding
Common Shares and 139,250 outstanding 8% Preferred Shares. The Purchaser owned
6,006,006 (approximately 31%) of those Common Shares. On that date, there also
were 3,060,470 Common Shares reserved for issuance on exercise of outstanding
options and warrants. The Shares owned by the Purchaser were acquired from the
Company in the Stock Purchase, which took place under the Merger Agreement on
December 5, 1997.
 
    Assuming no additional Shares are issued before the Expiration Time, the
Minimum Condition will be satisfied if at least 6,809,632 Common Shares and
92,834 8% Preferred Shares are properly tendered and not withdrawn before the
Expiration Time.
 
    Other conditions to consummation of the Offer are described in Section 5.
The Purchaser expressly reserves the right, in its sole discretion, to waive any
of the conditions to the Offer. See Section 5.
 
    THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

<PAGE>
                                THE TENDER OFFER
 
    1.  TERMS OF THE OFFER.  On the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and conditions
of the extension or amendment), the Purchaser will accept for payment and pay
for all Shares validly tendered prior to the Expiration Time and not withdrawn
in accordance with Section 4. The term "Expiration Time" means 12:00 midnight,
New York City time, on Friday, January 9, 1998, unless the Purchaser extends the
period during which the Offer is open, in which event the term "Expiration Time"
will mean the time and date at which the Offer, as extended, will expire.
 
    In the Merger Agreement, the Purchaser has agreed that it will not extend
the Offer to a date which is more than 60 days after the Offer is commenced,
except that (a) if the Offer is modified during the period it is open to
increase the price per share payable in the Offer or in any other manner
permitted by the Merger Agreement, the Offer many be extended until not more
than 10 business days after the day on which the modification is communicated to
the Company's stockholders, (b) if anyone makes a tender offer for either the
Common Shares or the 8% Preferred Shares before the Offer expires, the Offer may
be extended until not more than 10 business days after the other tender offer
expires, (c) if the Purchaser is prevented by an order of a court or other
governmental agency from accepting Shares which are tendered, the Offer may be
extended until 10 business days after the Purchaser is able to accept Shares
without violating any order of any court or other governmental agency and (d) if
the Minimum Condition is not satisfied by the scheduled Expiration Time, the
Offer may be extended for up to an additional 60 days to enable the Minimum
Condition to be satisfied (and if, although the Minimum Condition is not
satisfied, at least 2,500,000 Common Shares and at least 35,000 8% Preferred
Shares are properly tendered and not withdrawn, the Purchaser will extend the
Offer for at least an additional 30 days to enable the Minimum Condition to be
satisfied).
 
    The Purchaser also has agreed in the Merger Agreement that it will not (a)
decrease the number of Shares being tendered for in the Offer, (b) reduce the
Purchase Price either for the Common Shares or for the 8% Preferred Shares, (c)
modify or add to the conditions described in Section 5, (d) change the form of
consideration payable in the Offer, or (e) extend the Offer, except as required
or permitted by the Merger Agreement (which is described above).
 
    The Purchaser reserves the right, at any time and from time to time, to
extend the period during which the Offer is open, by giving oral or written
notice of the extension to the Depositary and by making a public announcement of
it as described below. During any extension, all Shares previously tendered and
not withdrawn will remain tendered in response to the Offer, subject to the
rights of a tendering stockholder to withdraw tendered Shares. See Section 4.
 
    Subject to the Merger Agreement and the applicable regulations of the
Securities and Exchange Commission (the "Commission"), the Purchaser reserves
the right, at any time and from time to time, to (i) delay acceptance for
payment of, or, regardless of whether Shares were already accepted for payment,
payment for, Shares pending receipt of any regulatory or third-party approval
described in Section 16 or in order to comply in whole or in part with any other
applicable law, (ii) terminate the Offer and not accept for payment any Shares
if any of the conditions described in Section 5 have not been satisfied or upon
the occurrence of any of the events described in Section 5 or (iii) waive any
condition or otherwise amend the Offer in any respect, in each case, by giving
oral or written notice of the delay, termination, waiver or amendment to the
Depositary and by making a public announcement of it, as described below.
 
    The Purchaser acknowledges that (i) Rule 14e-1(c) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") requires the Purchaser to
pay the consideration offered or return the tendered Shares promptly after the
termination or withdrawal of the Offer and (ii) the Purchaser may not delay
acceptance for payment of, or payment for (except as provided in clause (i) of
the first sentence of the preceding paragraph), any Shares upon the occurrence
of any of the events described in Section 5 without extending the period of time
during which the Offer is open.
 
                                       3
<PAGE>
    The Purchaser will make a public announcement of any extension, delay,
termination, waiver or amendment as promptly as practicable after it takes
place. In the case of an extension, a public announcement will be made no later
than 9:00 a.m., New York City time, on the business day after the day of the
previously scheduled Expiration Time. Subject to applicable law (including Rules
14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act, which require that material
changes be promptly disseminated to stockholders in a manner reasonably designed
to inform them of the changes), the Purchaser will have no obligation to
publish, advertise or otherwise communicate any public announcement other than
by issuing a press release.
 
    If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or if it waives a material condition to the
Offer, the Purchaser will extend the Offer to the extent required by Rules
14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. Consummation of the Offer
is conditioned upon satisfaction of the Minimum Condition, and the other
conditions set forth in Section 5. The Purchaser reserves the right (but will
not be obligated) to waive any or all of those conditions.
 
    If, prior to the Expiration Time, the Purchaser should decide to increase
the consideration being offered in the Offer, that increase will be applicable
to all stockholders whose Shares are accepted for payment, including
stockholders who tender their shares before the Purchaser increases the
consideration. If, at the time notice of an increase in the consideration being
offered is first published or otherwise given to holders of Shares, the Offer is
scheduled to expire earlier than the tenth business day after (but including)
the day the notice is first published or otherwise given, the Offer will be
extended at least until the expiration of that ten-business-day period. The
Purchaser does not expect to increase the consideration being offered.
 
    The Company has given the Purchaser a stockholder list and security position
listings for the purpose of enabling the Purchaser to disseminate the Offer to
holders of Shares. This Offer to Purchase and the related Letter of Transmittal
and other relevant materials will be mailed to record holders of Shares and to
brokers, dealers, commercial banks, trust companies and similar persons whose
names, or the names of whose nominees, appear on the Company's stockholder list,
or who are listed as participants in a clearing agency's security position
listing for subsequent transmittal to beneficial owners of Shares.
 
    2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.  On the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of the extension or amendment), the Purchaser will
purchase, by accepting for payment, and will pay for, all Shares which are
validly tendered (and not properly withdrawn in accordance with Section 4) prior
to the Expiration Time. Shares will be accepted as soon as practicable after the
later to occur of (i) the Expiration Time and (ii) the satisfaction or waiver of
the conditions set forth in Section 5. Any determination concerning the
satisfaction of the terms and conditions of the Offer will be in the sole
discretion of the Purchaser. See Section 5. The Purchaser expressly reserves the
right, in its sole discretion, to delay acceptance for payment of, or, subject
to the applicable rules of the Commission, payment for, Shares in order to
comply in whole or in part with any applicable law. See Section 16.
 
    In all cases, payment for Shares which are tendered in response to the Offer
and accepted for payment will be made only after timely receipt by the
Depositary of (a) the certificate(s) representing the tendered Shares (the
"Share Certificates"), or timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") of the Shares (if that procedure is available) into
the Depositary's account at The Depository Trust Company (the "Book-Entry
Transfer Facility"), as described in Section 3, (b) a properly completed and
duly executed Letter of Transmittal (or facsimile of one), or an Agent's Message
in connection with a book-entry transfer, and (c) any other documents required
by the Letter of Transmittal.
 
    An "Agent's Message" is a message, transmitted by the Book-Entry Transfer
Facility to, and received by, the Depositary and forming a part of the
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from a participant in the Book-Entry Transfer
 
                                       4
<PAGE>
Facility which tenders Shares that the participant has received, and agrees to
be bound by the terms of, the Letter of Transmittal and that the Purchaser may
enforce that agreement against the participant.
 
    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, tendered Shares when the Purchaser gives oral or
written notice to the Depositary of the Purchaser's acceptance of the Shares for
payment. Payment for Shares which are accepted will be made by deposit of the
aggregate purchase price for all the Shares which are accepted for payment with
the Depositary, which will act as agent for tendering stockholders for the
purpose of receiving payment from the Purchaser and transmitting payment to the
tendering stockholders. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE OFFER PRICE
BE PAID BY THE PURCHASER BY REASON OF ANY DELAY IN PAYING FOR SHARES. Upon the
deposit of funds with the Depositary for the purpose of making payments to
tendering stockholders, the Purchaser's obligation to pay for Shares will be
satisfied and tendering stockholders must look solely to the Depositary for
payment of amounts owed to them by reason of the acceptance of their Shares
pursuant to the Offer. If, for any reason, acceptance for payment of or payment
for any Shares tendered in response to the Offer is delayed, or the Purchaser is
prevented from accepting for payment or paying for Shares which are tendered in
response to the Offer, the Depositary may, nevertheless, retain tendered Shares
on behalf of the Purchaser and those Shares may not be withdrawn, except to the
extent the tendering stockholder exercises withdrawal rights as described in
Section 4. The Purchaser will pay any stock transfer taxes incident to the
transfer to it of validly tendered Shares, except as otherwise provided in
Instruction 6 of the Letter of Transmittal, as well as any charges and expenses
of the Depositary and the Information Agent.
 
    If any tendered Shares are not accepted for payment for any reason, or if
certificates which are submitted evidence more Shares than are tendered,
certificates representing unpurchased or untendered Shares will be returned or
sent, without expense to the tendering stockholder (or, in the case of Shares
tendered by book-entry transfer into the Depositary's account at the Book-Entry
Transfer Facility, Shares which are not purchased will be credited to an account
at that Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.
 
    IF, PRIOR TO THE EXPIRATION TIME, THE PURCHASER INCREASES THE CONSIDERATION
OFFERED TO HOLDERS OF SHARES TENDERED IN RESPONSE TO THE OFFER, THE INCREASED
CONSIDERATION WILL BE PAID TO ALL HOLDERS WHOSE SHARES ARE PURCHASED THROUGH THE
OFFER, INCLUDING HOLDERS WHOSE SHARES ARE TENDERED BEFORE THE CONSIDERATION IS
INCREASED.
 
    The Purchaser reserves the right to transfer or assign, in whole, or in part
from time to time, to one or more of its affiliates the right to purchase all or
any portion of the Shares which are tendered in response to the Offer, but such
a transfer or assignment will not relieve the Purchaser of its obligations under
the Offer and will in no way prejudice the rights of tendering stockholders to
receive payment for Shares which are validly tendered in response to the Offer
and accepted for payment.
 
    3. PROCEDURES FOR TENDERING SHARES.
 
    VALID TENDER OF SHARES. Except as set forth below, in order for Shares to be
validly tendered in response to the Offer, (a) a Letter of Transmittal or a
facsimile of one, properly completed and duly executed, with any required
signature guarantees, or an Agent's Message in connection with a book-entry
delivery of Shares, and any other required documents, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Time and (b) either (i) the certificates
representing the tendered Shares must be received by the Depositary along with
the Letter of Transmittal, (ii) the Shares must be tendered using the procedure
for book-entry transfer described below, and the Book-Entry Confirmation must be
received by the Depositary prior to the Expiration Time, or (iii) the tendering
stockholder must comply with the guaranteed delivery procedures described below.
 
                                       5
<PAGE>
    THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER. ITEMS WILL BE
DEEMED DELIVERED ONLY WHEN THEY ARE ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
 
    BOOK-ENTRY TRANSFER.  The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer within two business days after the date of
this Offer to Purchase, and any financial institution that is a participant in
the Book-Entry Transfer Facility's system may make book-entry delivery of Shares
by causing the Book-Entry Transfer Facility to transfer the Shares into the
Depositary's account at the Book-Entry Transfer Facility. Although delivery of
Shares may be effected through book-entry transfer at the Book-Entry Transfer
Facility, a Letter of Transmittal or a facsimile of one, with any required
signature guarantees, or an Agent's Message in connection with a book-entry
delivery of Shares, and any other required documents, as well as the Book Entry
Confirmation relating to the Shares, must be transmitted to and received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Time or the guaranteed delivery procedures
described below must be followed.
 
    REQUIRED DOCUMENTS MUST BE TRANSMITTED TO AND RECEIVED BY THE DEPOSITARY AT
ONE OF ITS ADDRESSES SET FORTH ON THE BACK COVER PAGE OF THIS OFFER TO PURCHASE.
DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE
DELIVERY TO THE DEPOSITARY.
 
    SIGNATURE GUARANTEES.  Signatures on Letters of Transmittal need not be
guaranteed, unless the Shares to which they relate are being tendered by a
registered holder of Shares who has completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on the
Letter of Transmittal. Signatures on Letters of Transmittal on which either of
those boxes has been completed must be guaranteed by a firm which is a bank,
broker, dealer, credit union, savings association or other entity that is a
member in good standing of the Securities Transfer Agents Medallion Program
(each an "Eligible Institution"). See Instruction 1 of the Letter of
Transmittal.
 
    If a Share Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or
certificates representing shares which are not tendered or are not accepted for
payment are to be returned, to a person other than the registered holder(s),
then the Share Certificate must be endorsed or accompanied by appropriate stock
powers, in either case, signed exactly as the name(s) of the registered
holder(s) appear on the Share Certificate, with the signature(s) on the Share
Certificate or stock powers guaranteed. See Instructions 1 and 5 of the Letter
of Transmittal.
 
    If Share certificates are delivered to the Depositary at different times, a
properly completed and duly executed Letter of Transmittal (or facsimile of one)
must accompany each delivery.
 
    GUARANTEED DELIVERY.  If a stockholder wishes to tender Shares in response
to the Offer but the Share Certificates are not immediately available or time
will not permit all required documents to reach the Depositary prior to the
Expiration Time, or the procedure for book-entry transfer cannot be completed on
a timely basis, the Shares may nevertheless be tendered as follows:
 
        (i) the tender must be made by or through an Eligible Institution;
 
        (ii) a properly completed and duly executed Notice of Guaranteed
    Delivery, substantially in the form provided with this Offer to Purchase,
    must be received by the Depositary before the Expiration Time; and
 
                                       6
<PAGE>
       (iii) the Share Certificates representing all tendered Shares, in proper
    form for transfer, or the Book-Entry Confirmation, together with a properly
    completed and duly executed Letter of Transmittal (or facsimile of one),
    with any required signature guarantees (or, in the case of a book-entry
    transfer, an Agent's Message) and any other documents required by the Letter
    of Transmittal are received by the Depositary within three (3) New York
    Stock Exchange trading days after the date of execution of the Notice of
    Guaranteed Delivery.
 
    A Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mail to the Depositary, but must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery distributed with this Offer to Purchase.
 
    Payment for Shares which are accepted for payment will be made only after
timely (i) receipt by the Depositary of Share Certificates for, or of Book-Entry
Confirmation with respect to, the Shares, (ii) a properly completed and duly
executed Letter of Transmittal (or facsimile of one), together with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message) and (iii) any other documents required by the Letter of Transmittal.
Accordingly, it is possible that payment will not be made to all tendering
stockholders at the same time.
 
    BACKUP UNITED STATES FEDERAL WITHHOLDING TAX.  Under the United States
Federal income tax laws, the Depositary may be required to withhold 31% of the
amount of any payments made to certain stockholders. To prevent backup Federal
income tax withholding, each tendering stockholder must provide the Depositary
with the stockholder's correct taxpayer identification number, or certify that
the stockholder is exempt from backup Federal income tax withholding, by
completing the Substitute Form W-9 included in the Letter of Transmittal. See
Instruction 10 of the Letter of Transmittal.
 
    APPOINTMENT AS PROXY.  By executing a Letter of Transmittal, a tendering
stockholder irrevocably appoints designees of the Purchaser as the tendering
stockholder's attorneys-in-fact and proxies, in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of the stockholder's rights with respect to the Shares tendered by the
stockholder and accepted for payment by the Purchaser (and with respect to any
other securities issued in respect of those Shares on or after the date of this
Offer to Purchase). That proxy is considered coupled with an interest in the
tendered Shares. This appointment will be effective if, when and to the extent
that the Purchaser accepts the tendered Shares for payment pursuant to the
Offer. When tendered Shares are accepted for payment, all prior proxies given by
the stockholder with respect to the tendered Shares and any other securities
issued in respect of them will, without further action, be revoked, and no
subsequent proxies may be given. The designees of the Purchaser will, with
respect to the tendered Shares and any other securities for which the
appointment is effective, be empowered to exercise all voting and other rights
of the tendering stockholder as they, in their sole discretion, deem proper at
any annual, special, adjourned or postponed meeting of the Company's
stockholders, and the Purchaser reserves the right to require that in order for
Shares or other securities to be deemed validly tendered, immediately upon the
Purchaser's acceptance for payment of the Shares, the Purchaser will be able to
exercise full voting rights with respect to the Shares.
 
    Proxies are effective only as to Shares accepted for payment pursuant to the
Offer. The Offer does not constitute a solicitation of proxies, absent a
purchase of Shares, for any meeting of the Company's stockholders. Any
solicitation of proxies will be made only pursuant to separate proxy
solicitation materials complying with the Exchange Act.
 
    DETERMINATIONS REGARDING TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any Shares
using any of the procedures described above will be determined by the Purchaser,
in its sole discretion, and the Purchaser's determination will be final and
binding on all parties. The Purchaser reserves the absolute right to reject any
or all tenders of Shares determined by it not to be in proper form or if the
acceptance for payment of, or payment for, the Shares may, in the opinion of the
Purchaser's counsel, be unlawful. The Purchaser also reserves the absolute
right,
 
                                       7
<PAGE>
in its sole discretion, to waive any of the conditions of the Offer or any
defect or irregularity in any tender with respect to Shares of any particular
stockholder, whether or not similar defects or irregularities are waived in the
case of other stockholders. No tender of Shares will be deemed to have been
validly made until all defects and irregularities have been cured or waived.
 
    The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions to it) will be final
and binding. None of Parent, the Purchaser, either Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or will incur any
liability for failure to give any such notification.
 
    BINDING AGREEMENT.  The Purchaser's acceptance for payment of Shares
tendered in response to the Offer will constitute a binding agreement by the
tendering stockholder to sell, and by the Purchaser to purchase, the tendered
Shares on the terms and subject to the conditions of the Offer.
 
    4.  WITHDRAWAL RIGHTS.  Except as otherwise provided in this Section 4,
tenders of Shares made in response to the Offer are irrevocable. Shares tendered
in response to the Offer may be withdrawn at any time prior to the Expiration
Time and, unless they have been accepted for payment by the Purchaser, may also
be withdrawn at any time after February 9, 1998.
 
    If the Purchaser extends the Offer, is delayed in its acceptance of Shares
for payment or is unable to accept Shares for payment for any reason, then,
without prejudice to the Purchaser's rights under the Offer, the Depositary may,
nevertheless, retain tendered Shares on behalf of the Purchaser, and those
Shares may not be withdrawn except to the extent that tendering stockholders are
entitled to withdraw them as described in this Section 4. Any such delay will be
accompanied by an extension of the Offer to the extent required by law.
 
    For a withdrawal to be effective, a written or facsimile transmission of a
notice of withdrawal must be timely received by the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase. A notice of
withdrawal must specify the name of the person who tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and (if Share Certificates have
been tendered) the name of the registered holder, if different from that of the
person who tendered the Shares. If Share Certificates evidencing Shares to be
withdrawn have been delivered or otherwise identified to the Depositary, then
prior to the release of those Share Certificates, the serial numbers shown on
the particular Share Certificates to be withdrawn must be submitted to the
Depositary, and the signature(s) on the notice of withdrawal must be guaranteed
by an Eligible Institution, unless the Shares have been tendered for the account
of an Eligible Institution. If Shares have been tendered pursuant to the
procedure for book-entry transfer, any notice of withdrawal must also specify
the name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares. Withdrawals of Shares may not be rescinded.
 
    After Shares are properly withdrawn, they will be deemed not to have been
validly tendered for purposes of the Offer. However, withdrawn Shares may be
retendered at any time prior to the Expiration Time using one of the procedures
described in Section 3.
 
    All questions as to the form and validity (including, without limitation,
time of receipt) of notices of withdrawal will be determined by the Purchaser,
in its sole discretion, and its determination will be final and binding. None of
Parent, the Purchaser, either Dealer Manager, the Depositary, the Information
Agent or any other person will be under any duty to give notification of any
defects or irregularities in any notice of withdrawal or will incur any
liability for failure to give any such notification.
 
    5.  CONDITIONS OF THE OFFER.  The Purchaser will not be required to accept
for payment or, subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) under the Exchange Act (relating to the
Purchaser's obligation to pay for or return tendered Shares promptly after
termination or withdrawal of the Offer), pay for, the Shares which are tendered

        (f) Since the date of the Merger Agreement, there has been an occurrence
    or group of occurrences (whether or not related) which have had a material
    adverse effect upon the Company (other than (i) occurrences which affected

    actual or proposed changes in laws or regulations, or (ii) the transactions
    contemplated by the Merger Agreement, including the change in control
    contemplated by it);
 
        (g) the Company has not performed all the obligations it is required to

    response to the Offer or the ability of the Purchaser and the Company to
    effect the Merger, (ii) have been caused by or result from a breach of the
    Merger Agreement by the Purchaser; or (iii) do not, and are not reasonably
    expected to, have a material adverse effect on the Company;
 
        (h) The Merger Agreement has been terminated in accordance with its
    terms; or
 
        (i) The Board of Directors of the Company withdraws or modifies in a
    manner adverse to the Purchaser the Board's approval or recommendation of
    the Offer or the Merger.
 
    The conditions set forth above are for the sole benefit of the Purchaser,
and may be waived by the Purchaser, in whole or in part. Any delay by the
Purchaser in exercising the right to terminate the Offer because any of the
conditions are not fulfilled will not be deemed a waiver of its right to do so.

    6. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
    The following summary is a general discussion of certain of the expected
Federal income tax consequences of the Offer. The summary is based on the
Internal Revenue Code of 1986, as amended (the "Code"), and published
regulations, rulings and judicial decisions in effect at the date of this Offer
to Purchase, all of which are subject to change. The summary does not discuss
all aspects of Federal income taxation that may be relevant to a particular
holder in light of his or her personal circumstances or to certain types of
holders subject to special treatment under the Federal income tax laws, such as
life insurance companies, financial institutions, tax-exempt organizations and
non-U.S. persons. The following summary may not be applicable with respect to
Shares acquired through exercise of employee stock options or otherwise as
compensation. It also does not discuss any aspects of state or local tax laws or
of tax laws of jurisdictions outside the United States of America.
 
    THE DESCRIPTION OF FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW IS FOR
GENERAL INFORMATION ONLY. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE SALE OF THEIR SHARES, INCLUDING
THE APPLICATION OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS AND POSSIBLE
CHANGES IN TAX LAWS.
 
    Sales of Shares in response to the Offer will be taxable transactions for
Federal income tax purposes, and may also be taxable transactions under
applicable state, local, foreign and other tax laws. For Federal income tax
purposes, a tendering stockholder will generally recognize gain or loss equal to
the difference between the amount of cash received by the stockholder upon sale
of the Shares and the aggregate tax basis in the Shares which are sold. Under
present law, gain or loss will be calculated separately for each block of Shares
tendered and purchased pursuant to the Offer.
 
    If tendered Shares are held by a tendering stockholder as capital assets,
gain or loss recognized by the tendering stockholder will be capital gain or
loss, which will be long-term capital gain or loss if the tendering
stockholder's holding period for the Shares exceeds one year. Long-term capital
gains recognized by a tendering individual stockholder will generally be taxed
at a maximum Federal marginal tax rate of 28% as to Shares held between 12 and
18 months and 20% as to shares held more than 18 months. Long-term capital gains
recognized by a tendering corporate stockholder will be taxed at a maximum
Federal marginal tax rate of 35%.
 
    A stockholder (other than certain exempt stockholders, including all
corporations and certain foreign individuals) who tenders Shares may be subject
to 31% backup withholding unless the stockholder provides its taxpayer
identification number ("TIN") and certifies that the TIN is correct or properly
certifies that it is awaiting a TIN. This should be done by completing and
signing the substitute Form W-9 included as part of the Letter of Transmittal. A
stockholder that does not furnish its TIN also may be subject to a penalty
imposed by the IRS.
 
    If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from each payment to that stockholder. Backup withholding is not
an additional tax. Rather, the amount of the backup withholding can be credited
against the Federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the stockholder upon filing an income tax return.

    9. CERTAIN INFORMATION CONCERNING THE PURCHASER AND PARENT.
 
    THE PURCHASER.  The Purchaser is a Delaware corporation organized in order
to enter into the transactions which are the subject of the Merger Agreement
(including the Offer). The principal executive offices of the Purchaser are
located at Godoy Cruz 316, Mendoza, Province of Mendoza, Argentina 5500. The
Purchaser is a wholly owned subsidiary of Parent. Until immediately prior to the
Stock Purchase, the Purchaser did not have any significant assets or liabilities
and had not engaged in activities other than those incidental to its formation
and capitalization and preparation for the Stock Purchase, the Offer and the
Merger. Due to the fact that the Purchaser is newly formed and, until the Stock
Purchase, had minimal assets and capitalization, no meaningful financial
information regarding the Purchaser is available.
 
    In the Stock Purchase, the Purchaser purchased 6,006,006 Common Shares
Preferred Shares for $3.33 per Common Share (a total of $20,000,000). That price
is lower than the price to be paid in the Offer and the Merger. However, the
terms of the Stock Purchase were agreed upon (a) to provide funds to the Company
at prices Parent and the Purchaser were willing to pay even if they did not
acquire the remaining shares of the Company, and (b) with knowledge that if the
Offer and the Merger were completed, Parent would own all the stock of the
Company, and therefore Parent would, in effect, become the owner of the proceeds
of the Stock Purchase (or of the benefits of application of those proceeds). The
Agreement provides that unless the Purchaser purchases all the Shares tendered
in response to the Offer (even if the Minimum Condition or other conditions are
not fulfilled), the Company will have an option, which will expire one year
after the date of the Stock Purchase, to repurchase the shares it sold in the
Stock Purchase for the price the Purchaser paid for those shares. See
"Description of the Agreement."
 
    PARENT.  Parent, a corporation organized under the laws of Argentina, is the
third largest multi-channel television system operator in Argentina, providing
multi-channel television services via cable and wireless technology. The
principal executive offices of Parent are located at Godoy Cruz 316, Mendoza,
Province of Mendoza, Argentina 5500.
 
    During the last 5 years none of Parent's or Purchaser's officers or
directors was (1) convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors) or (2) party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of the
proceeding was or is subject to a judgment, decree or final order enjoining
future violations of or prohibiting activities subject to, Federal or state
securities laws or finding any violation of such laws.
 
    Parent is not subject to the informational and reporting requirements of the
Exchange Act and Parent is not required to file reports and other information
with the Commission relating to its businesses, financial condition or other
matters.
 
    The name, citizenship, business address, principal occupation or employment
and five-year employment history for each of the directors and executive
officers of the Purchaser and Parent are set forth in Schedule I.
 
    Except for the 6,006,006 Common Shares acquired by the Purchaser on December
5, 1997 through the Stock Purchase described in this Offer to Purchase, none of
Parent, the Purchaser or, to the best knowledge of Parent or the Purchaser, any
of the persons listed on Schedule I or any associate or majority owned
subsidiary of any of those persons beneficially owns any equity security of the
Company, and none of Parent or the Purchaser or, to the best knowledge of Parent
or the Purchaser, any of the other persons referred to above, or any of their
respective directors, executive officers or subsidiaries, has effected any
transaction in any equity security of the Company during the past 60 days.
 
    Except as described in this Offer to Purchase, none of Parent or the
Purchaser or, to the best knowledge of Parent or the Purchaser, any of the
persons listed on Schedule I has any contract, arrangement, understanding or
relationship with any other person with respect to any securities of the
 
                                       13
<PAGE>
Company, including, without limitation, any contract, arrangement, understanding
or relationship concerning the transfer or the voting of any securities of the
Company, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
Except as set forth in this Offer to Purchase, none of Parent or the Purchaser
or, to the best knowledge of Parent or the Purchaser, any of the persons listed
on Schedule I has had any transactions with the Company or any of its executive
officers, directors or affiliates that would require reporting under the rules
of the Commission.
 
    Except as described in this Offer to Purchase, since January 1, 1994, there
have been no contacts, negotiations or transactions between Parent or the
Purchaser, or their respective subsidiaries, or, to the best knowledge of Parent
or the Purchaser, any of the persons listed in Schedule I, on the one hand, and
the Company or its executive officers, directors or affiliates, on the other
hand, concerning a merger, consolidation or acquisition, tender offer or other
acquisition of securities, election of directors or a sale or other transfer of
a material amount of assets.
 
    10. SOURCE AND AMOUNT OF FUNDS.  If all the outstanding Shares not owned by
the Purchaser were tendered in response to the Offer, the Purchaser would be
required to pay a total of approximately $86 million to purchase the tendered
Shares and pay the fees and other expenses related to the Offer. See Section 17.
The Purchaser expects to obtain the funds required to consummate the Offer
through capital contributions or advances made by Parent. Parent has guaranteed
the Purchaser's obligations under the Merger Agreement, including obligations
with respect to the Offer.
 
    On November 12, 1997, Parent entered into a $300,000,000 Note Purchase
Agreement (the "Loan Agreement") among Parent, and the other issuers named or
referred to therein, as issuers, the financial institutions party thereto, as
purchasers, ING Baring (U.S.) Securities, Inc. as Arranger, ING Baring (U.S.)
Capital Corporation, (the "Bank"), as Administrative Agent and Collateral Agent,
and The Bank of New York, as Registrar. One of the reasons Parent entered into
the Loan Agreement was to obtain the funds it would require for the transactions
which are the subject of the Merger Agreement. Parent expects to obtain
substantially all the funds which will be used to pay for tendered Shares and to
pay the fees and expenses related to the Offer through borrowings under the Loan
Agreement. It is permitted to use up to $135 million of borrowings (including
the $20 million paid in the Stock Purchase) for the transactions under the
Merger Agreement and to pay costs of those transactions. ING Baring (U.S.)
Securities, Inc., an affiliate of the Bank, acted as a financial advisor to
Parent in connection with the transactions which are the subject of the Merger
Agreement and is one of the Deal Managers with regard to the Offer.
 
    Borrowings under the Loan Agreement bear interest at LIBOR plus 4.5% per
annum and must be repaid by November 12, 2002. Parent anticipates that the
indebtedness under the Loan Agreement, including indebtedness incurred by Parent
in connection with the Stock Purchase, the Offer and the Merger, will be repaid
from funds generated internally by Parent and its subsidiaries (including, after
the Merger, if consummated, dividends paid by the surviving corporation and its
subsidiaries), through additional borrowings, through application of proceeds of
dispositions of assets or through a combination of two or more of those sources.
No final decisions have been made, however, concerning the method Parent will
employ to repay that indebtedness. Those decisions, when made, will be based on
Parent's review from time to time of the advisability of particular actions, as
well as on prevailing interest rates and financial and other economic
conditions.
 
    11. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.
 
    The initial discussions of a possible transaction between Parent and the
Company took place at a meeting in October 1996 between senior officers of the
Company and representatives of Integra Financial Services L.L.C ("Integra"), an
advisor to Parent. These initial discussions, and additional discussions through
March 1997, focused on the high degree of consolidation in the Argentine CATV
industry which
 
                                       14
<PAGE>
was taking place, and the advisability of combining the operations of Parent and
the Company in view of that consolidation.
 
    In April 1997, there were discussions about a merger of the Company and
Parent, in which shareholders of the Company would receive shares of Parent.
Extensive discussions were held, and draft agreements were prepared. However,
the merger would have required approval of the shareholders of both companies. A
shareholder of Parent, which had the ability to preclude Parent from carrying
out the merger, stated it would not approve a merger. Because of that,
discussions of a merger were dropped.
 
    Early in August 1997, discussions of a transaction between Parent and the
Company were revived. Parent was represented in these discussions by Integra,
ING Baring (U.S.) Securities, Inc. ("ING Baring Securities") and Smith Barney &
Co., Inc. ("Smith Barney"). The Company was represented in these discussions by
its senior officers and by Arnhold and S. Bleicholder & Co. ("Bleicholder"). By
mid-August, Parent and the Company each brought attorneys into the discussions,
and agreements began to be drafted.
 
    From mid-August to mid-September, there were nearly daily discussions of a
transaction between Parent and the Company. Initially, the discussions related
to a purchase by Parent from the Company of what would have been approximately
45% of the outstanding Common Shares and 30% of the outstanding 8% Preferred
Shares for approximately $39 million, followed by a merger of the Company into a
subsidiary of Parent in which the stockholders of the Company would have
received $4.53 per Common Share and $144.96 per 8% Preferred Share. However, at
Parent's suggestion, it was decided that the transaction would take place in
three steps, with a tender offer for the Common Shares and 8% Preferred Shares
between the initial stock purchase and the merger.
 
    A principal issue during the discussions was a desire of the Company to be
sure Parent would not become unable to complete a transaction either (i) because
it did not have adequate funds or (ii) because its shareholders would not permit
the transaction to proceed. With regard to the first concern, ING Baring (US)
Capital Corporation ("ING Baring Capital") delivered a letter to the Company
stating that ING Baring Capital had obtained internal credit approval for a
senior secured credit facility in an aggregate principal amount sufficient to
conclude the transactions being discussed, but the disbursement of that facility
was subject to the negotiation, execution and delivery of definitive
documentation satisfactory to ING Baring Capital and its counsel, which would
contain, among other things, customary covenants, conditions precedent and
security arrangements (including financial covenants on a pro forma basis
concerning the combined operations of Parent and the Company). With regard to
the second concern, the stockholders of Parent all stated they approved of the
transaction.
 
    On September 16, 1997, the Purchaser (a wholly-owned subsidiary of Parent)
and the Company signed a Stock Purchase and Merger Agreement (the "Original
Merger Agreement") in which they agreed that (i) the Purchaser would purchase
10,790,000 Common Shares (which would be approximately 45% of the outstanding
Common Shares) for $35,930,700 ($3.33 per share) and would purchase 60,750 8%
Preferred Shares (which would be 30% of the outstanding 8% Preferred Shares) for
$6,075,000 ($100 per share), (ii) shortly after completion of that stock
purchase, the Purchaser would make a tender offer for all the outstanding Common
Shares and 8% Preferred Shares for $4.50 per Common Share and $144 per 8%
Preferred Share (plus an amount equal to accrued dividends on the 8% Preferred
Shares), and (iii) if the tender offer resulted in the Purchaser's owning at
least two-thirds of the outstanding Common Shares and two-thirds of the
outstanding 8% Preferred Shares (which would enable the Purchaser to approve a
merger between the Company and itself even if no other Tescorp shareholders
voted in favor of the merger), the Company and the Purchaser would be merged in
a transaction in which Parent would become the sole shareholder of the merged
company and the former Tescorp shareholders who had not tendered their shares
would receive $4.50 per Common Share and $144 per 8% Preferred Share plus
accrued dividends, unless they sought to obtain appraisal of their shares in
accordance with Articles 5.11 through 5.13 of the Texas Business Corporation
Act. The Original Merger Agreement required that before the Purchaser purchased
the 10,790,000 Common Shares and the 60,750 8% Preferred Shares, three designees
of the
 
                                       15
<PAGE>
Purchaser would be elected to the Company's Board of Directors. When the
Original Merger Agreement was signed, the Purchaser gave the Company a
$5,000,000 deposit, to be applied against the purchase price of the 10,790,000
Common Shares and the 60,750 8% Preferred Shares.
 
    After the Original Merger Agreement was signed, required filings were made
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and
the waiting periods required by that Act were terminated. Also, agreements
between Parent and various financial institutions, including ING Bank N.V.,
which included the financing required for the transaction contemplated by the
Original Merger Agreement were drafted. However, before those financing
agreements were signed, it was realized that the purchase by the Purchaser of
45% of the Common Shares and 30% of the 8% Preferred Shares would not result in
the Company's financial statements being included in Parent's consolidated
financial statements, and therefore, that step of the transaction would cause
Parent to be in violation of financial ratio covenants which would be in the
financing agreements.
 
    On November 5, 1997, representatives of Parent informed the principal
executive officers of the Company that, because of requirements of Parent's
expected lending agreements, Parent and the Purchaser would not be able to carry
out the transaction as contemplated by the Original Merger Agreement.
Discussions ensued, and on December 5, 1997 the Purchaser and the Company
entered into an Amended Stock Purchase and Merger Agreement (the "Merger
Agreement"). The principal difference between the Merger Agreement and the
Original Merger Agreement is that under the Merger Agreement, the initial step
was the purchase by the Purchaser of 6,006,006 Common Shares for $20,000,000
(including $5,000,000 paid through application of the deposit given when the
Original Merger Agreement was signed), rather than the purchase of 10,790,000
Common Shares and 60,750 8% Preferred Shares for $42,005,700 which had been
contemplated by the Original Merger Agreement. Because this initial transaction
would be smaller than had been contemplated in the Original Merger Agreement,
provisions were added to the Merger Agreement which were intended to insure that
the proceeds of the initial transaction would give the Company the cash it
needed for specified transactions (including a debt repayment due in February
1998) and the number of directors of the Company the Purchaser could designate
was reduced from three to one.
 
    In accordance with the Merger Agreement, on December 5, 1997, (i) the
Purchaser purchased a total of 6,006,006 Common Shares for $20,000,000 ($3.33
per share), of which $15 million was paid in cash and the balance was paid by
permitting the Company to keep the $5 million deposit which the Purchaser had
given to the Company when the Original Merger Agreement was signed, and (ii) the
Offer was announced. The Merger Agreement required that materials relating to
the Offer be sent to the Company's stockholders, and requires that if the
Purchaser increases its ownership to at least two-thirds of the outstanding
Common Shares and obtains at least two-thirds of the outstanding 8% Preferred
Shares through the Offer (i.e., the Minimum Condition is satisfied), the merger
contemplated by the Merger Agreement will take place. The Merger Agreement is
described under the caption "The Merger Agreement."
 
    12. PURPOSE OF THE OFFER AND THE PROPOSED MERGER; PLANS FOR THE COMPANY.
 
    PURPOSE.  The purpose of the Stock Purchase, the Offer and the Merger is to
enable Parent to acquire all the outstanding stock of the Company. The Offer is
the second step in this effort. In the Stock Purchase, Parent, through the
Purchaser, acquired approximately 31% of the outstanding Common Shares. If the
Purchaser accepts Shares tendered in response to the Offer, the Purchaser's (and
indirectly Parent's) ownership of Common Shares and 8% Preferred Shares will
increase by the number of Shares purchased through the Offer. The purpose of the
Merger will be to enable Parent to become the owner of all the outstanding stock
of the Company.
 
    If the Purchaser purchases through the offer at least the minimum number of
Common Shares and 8% Preferred Shares required to satisfy the Minimum Condition,
Parent will be required by the Merger Agreement to carry out the Merger. If
Purchaser purchases the shares which are properly tendered in response to the
Offer, but those shares do not increase the Purchaser's holdings sufficiently to
satisfy the
 
                                       16
<PAGE>
Minimum Condition, neither Parent nor the Company will be contractually
obligated to carry out the Merger. However, unless the Loan Agreement is
modified, the Purchaser will not be permitted to waive the Minimum Condition (or
any other condition to its obligation to accept and pay for the Shares which are
tendered in response to the Offer).
 
    If, because one or more of the conditions to the Purchaser's obligation to
accept Shares which are tendered in response to the Offer is not fulfilled, the
Purchaser does not purchase the Shares which are tendered in response to the
Offer, the Company will have the option, which it may exercise at any time on or
before December 5, 1998 (the first anniversary of the date on which the Stock
Purchase was completed), to repurchase all the stock the Purchaser acquired
through the Stock Purchase for the price the Purchaser paid for it. If, however,
the Purchaser purchases all the Shares which are tendered in response to the
Tender Offer, even though it is not required to do so, the Company will not have
the option to repurchase the stock the Purchaser acquired through the Stock
Purchase.
 
    The Purchaser is also required to purchase, at or before the Effective Time
of the Merger, the minority interests in some cable television systems of which
the Company is the majority owner, except to the extent the current owners of
the minority interests will not sell them for prices specified in the Merger
Agreement. The Purchaser also is required to purchase two local cable systems
which were the subject of options held by the Company, if the owners of these
systems will sell them on the terms provided in the options. There is no
provision of the Merger Agreement giving the Company the right, or the
obligation, to purchase the minority interests or the two cable systems from the
Purchaser if the Purchaser purchases them but the Merger does not take place.
 
    If Parent acquires all the stock of the Company, Parent will include the
Company's cable systems in Parent's network of Argentine cable systems. If that
occurs, Parent may make changes in the way those cable systems are operated, in
the corporate structure of those cable systems or in their personnel. Parent
also may liquidate the Company so Parent or another subsidiary of Parent will be
the sole owner of the Argentine cable systems currently owned or operated by the
Company. Except as described, neither the Purchaser nor Parent has any current
plans or proposals that would relate to, or result in, any extraordinary
corporate transaction involving the Company, such as a merger, reorganization or
liquidation involving the Company or any of its subsidiaries, a sale or transfer
of a material amount of assets of the Company or any of its subsidiaries, any
changes in the Company's capitalization or dividend policy or any other material
change in the Company's business, corporate structure or personnel.
 
    In accordance with the Merger Agreement, effective December 5, 1997, Daniel
Vila, was elected to the Company's Board of Directors. The Company is required
to use its best efforts to cause Daniel Vila, or if he becomes unable to serve,
another designee of the Purchaser reasonably acceptable to the Company, to be
elected at all subsequent meetings of the Company's stockholders at which
directors are elected. If (i) at any time the Purchaser and its affiliates
(including Parent) cease to own at least 15% of the outstanding Common Shares,
or (ii) the Purchaser breaches or fails to fulfill in a material respect any of
its obligations under the Merger Agreement within 10 days after written notice
of the failure from the Company, the Purchaser must cause Daniel Vila or whoever
else may be its designee to resign.
 
    ACQUISITION PROPOSALS.  The Company may not, and may not authorize its
officers, directors, employees or agents to, enter into any discussions or take
any other steps, a likely result of which might be to cause someone other than
the Purchaser or Parent to (i) solicit tenders of stock of the Company or
otherwise seek to acquire 5% or more of either the Common Shares or the 8%
Preferred Shares, other than with a view to tendering those Shares in response
to the Offer, (ii) acquire all or a substantial portion of the assets of the
Company and its subsidiaries (whether through acquisitions of assets,
acquisitions of stock of subsidiaries or both), or (iii) otherwise acquire the
Company or a substantial portion of its assets if the Minimum Condition is not
met or if the Company's stockholders do not approve the Merger. The Company is
required to notify the Purchaser if the Company learns that anyone is
contemplating soliciting tenders of its stock, acquiring 5% or more of its
outstanding stock, acquiring all or a substantial portion of
 
                                       17
<PAGE>
its assets and those of its subsidiaries or otherwise offering to acquire the
Company or its assets if the Minimum Condition is not met or if its stockholders
do not approve the Merger, and to provide the Purchaser with any additional
information it obtains regarding the contemplated solicitation of tenders,
acquisition of stock or assets or other acquisition offer.
 
    If there is an unsolicited tender offer from someone other than the
Purchaser which the Company's Board of Directors determines, in good faith and
after consultation with the Company's independent financial advisor, (i) would
result in the holders of the Common Shares receiving consideration with a fair
value of more than $5.00 per share and the holders of the 8% Preferred shares
receiving consideration with a fair value of more than $160 per share, and (ii)
is more favorable both to the holders of the Common Shares than the transactions
under the Merger Agreement and to the holders of the 8% Preferred Shares the
Company may terminate the Merger Agreement by paying the Purchaser $5 million.
See Section 13.
 
    13. THE MERGER.
 
    THE MERGER AGREEMENT.  The Merger Agreement provides that if the Purchaser
acquires enough Shares through the Offer to satisfy the Minimum Condition,
following the satisfaction or waiver of the conditions described below under
"Conditions to the Merger", the Purchaser will be merged with and into the
Company, which will be the surviving corporation of the Merger (the "Surviving
Corporation"). When the Merger becomes effective, the separate existence of the
Purchaser will terminate, the Purchaser's real and personal property, other
assets, rights, privileges, immunities, powers, purposes and franchises will be
merged into the Surviving Corporation, and the Merger will have the other
effects specified in Section 259 of the Delaware General Corporate Law and
Article 5.06 of the Texas Business Corporation Act (the "TBCA").
 
    STOCK OF THE COMPANY.
 
    (a) At the Effective Time of the Merger, each Common Share which is
outstanding immediately before the Effective Time, other than shares owned by
the Purchaser, will be converted into and become the right to receive $4.50 in
cash, or any higher price per share paid with regard to Common Shares tendered
in response to the Offer (the "Common Shares Merger Price").
 
    (b) At the Effective Time each 8% Preferred Share which is outstanding
immediately before the Effective Time will be converted into and become the
right to receive in cash $144 per share plus accrued dividends to the Expiration
Date of the Offer (except that if a dividend is paid with regard to the 8%
Preferred Shares between the Expiration Time and the Effective Time, each 8%
Preferred Share will be converted into and become the right to receive $144.00
in cash without regard to any accrued but unpaid dividends).
 
    (c) At the Effective Time, each Common Share or 8% Preferred Share held by
the Purchaser or by any direct or indirect subsidiary of the Company immediately
before the Effective Time will be cancelled and no payment will be made with
respect to those shares.
 
    STOCK OF THE PURCHASER.  At the Effective Time, each share of stock of the
Purchaser which is outstanding immediately before the Effective Time will be
converted into and become one share of common stock of the Surviving Corporation
("Surviving Corporation Common Stock").
 
    STOCKHOLDER VOTE REQUIRED TO APPROVE MERGER.  Under the TBCA, the
affirmative vote of holders of two-thirds of the outstanding Shares (including
any Shares owned by the Purchaser) is required to approve the Merger. If the
Minimum Condition is satisfied and the Purchaser purchases the Shares tendered
in response to the Offer, the Purchaser will it have sufficient voting power to
approve the Merger without the vote of any other stockholder of the Company. If
the Purchaser acquires more than 90% of the outstanding shares, stockholder
approval will not be required under TBCA Article 5.16.
 
                                       18
<PAGE>
    STOCKHOLDERS MEETING.  If the Minimum Condition is satisfied and the
Purchaser purchases the Shares tendered in response to the Offer, and if
approval by the Company's stockholders is required in order to consummate the
Merger, the Company will hold a special meeting of its stockholders as soon as
practicable after the Expiration Time for the purpose of adopting the Merger
Agreement and approving the Merger.
 
    CONDITIONS TO THE MERGER.  Neither the Company nor the Purchaser is
contractually obligated to complete the Merger unless the Purchaser acquires the
Shares tendered in response to the Offer and the Minimum Condition is satisfied.
If that occurs (i) the Purchaser will own sufficient shares to be able to
approve the Merger even if no other stockholders of the Company vote in favor of
it and (ii) the Purchaser will be contractually obligated to vote in favor of
the Merger. The obligations of the Company to carry out the Merger will be
conditioned on the Merger's being approved by the holders of two-thirds of the
outstanding Common Shares and two-thirds of the outstanding 8% Preferred Shares
(which will occur if the Minimum Condition is satisfied and the Purchaser votes
in favor of the Merger). In addition, the obligations of the Company and of the
Purchaser complete the Merger are subject to the following conditions: (a) no
order will have been entered by any court or governmental authority and be in
force which invalidates the Merger Agreement or restrains the Company from
completing the transactions contemplated by the Merger Agreement; (b) the
Effective Time will occur on or before April 30, 1998; (c) the number of shares
held by shareholders of the Company who have filed written objections to
approval of the Merger sufficient to preserve their rights to demand the fair
value of the shares pursuant to Articles 5.11 through 5.13 of the TBCA will not
exceed 5% of the total number of outstanding Common Shares and 8% Preferred
Shares combined (treating each 8% Preferred Share as being equal to 32 Common
Shares).
 
    TERMINATION OF THE MERGER AGREEMENT.  The Merger Agreement may be terminated
at any time prior to the Effective Time of the Merger (as defined below),
whether before or after approval of the terms of the Merger Agreement by the
stockholders of the Company:
 
        (1) by mutual consent of the Company and the Purchaser;
 
        (2) by the Company, if without fault of the Company, the Expiration Time
    of the Offer is not on or before January 31, 1998;
 
        (3) by the Company or the Purchaser if, without fault of the Purchaser,
    the Effective Time of the Merger is not on or before April 30, 1998;
 
        (4) by the Company if (i) if any of the representations and warranties
    of the Purchaser contained in the Merger Agreement was not complete and
    accurate in all material respects on the date of the Merger Agreement or
    (ii) any of the conditions to the Company's obligations to complete the
    Merger are not satisfied or waived by the Company prior to or on the date of
    the Merger;
 
        (5) by the Purchaser if (i) any of the representations or warranties of
    the Company contained in the Merger Agreement was not complete and accurate
    in all material respects on the date of the Merger Agreement, or (ii) any of
    the conditions to the Purchaser's obligations to complete the Merger are not
    satisfied or waived by the Purchaser prior to or on the date of the Merger;
    or
 
        (6) by the Company if (A) a tender or exchange offer is commenced by a
    potential acquiror for all the outstanding Common Shares and 8% Preferred
    Shares for a consideration having a value of at least $5 per Common Share
    and $160 per 8% Preferred Share, (B) the Company's Board of Directors
    determines in good faith and after consultation with an independent
    financial advisor that the offer constitutes a Superior Proposal (as defined
    below) and resolves to accept the Superior Proposal or to recommend to the
    Company's stockholders that they tender their shares in response to the
    tender or exchange offer (C) the Company has given the Purchaser at least 10
    business days' prior notice of its intention to terminate pursuant to this
    provision and (D) the Company has paid the Purchaser $5 million. A "Superior
    Proposal" is an unsolicited proposal to the Company which (x) would result
    in the Company's stockholders receiving consideration with a fair value
    determined in good faith by the
 
                                       19
<PAGE>
    Company's Board of Directors and after consultation with the Company's
    independent financial advisor to be more than $5 per share of Common Stock
    and more than $160 per share of 8% Preferred Stock and (y) is determined in
    good faith by the Company's Board of Directors to be more favorable both to
    the holders of Common Shares and to the holders of the 8% Preferred Shares
    than the Offer and the Merger.
 
    EFFECT OF TERMINATION OF THE MERGER AGREEMENT.  If the Merger Agreement is
terminated, neither the Company nor the Purchaser will be required to complete
the Merger. If the Merger Agreement is terminated after the Purchaser has
accepted Shares tendered in response to the Offer, the termination will not
affect the Purchaser's purchase of the Shares it has accepted or its obligation
to pay for those shares. If the Purchaser waives the Minimum Condition and votes
in favor of the Merger, but the Merger is not approved by the Company's
stockholders, the Company will have to pay the Purchaser $5 million.
 
    ACQUISITION PROPOSALS.  The Merger Agreement contains prohibitions against
the Company's soliciting, or authorizing its officers, directors, employees or
agents to solicit acquisition proposals, and regarding what the Company may do,
if it receives unsolicited acquisition proposals.
 
    OTHER PROVISIONS.  The Merger Agreement also contains provisions (i)
requiring the Company to operate its business in the ordinary course, including
maintaining the goodwill of its business and maintaining its assets in good
condition, limiting the Company's borrowings and commitments for capital
expenditures, and precluding the Company from paying dividends (other than
required dividends with regard to its preferred stock) or taking other steps
regarding its stock, until the Effective Time, (ii) requiring the Purchaser (and
the corporation which survives the Merger) to indemnify directors, officers,
employees, fiduciaries and agents of the Company and its subsidiaries against
liability rising out of their service as directors, officers, employees or
agents of the Company or its subsidiaries, or of companies with regard to which
they served as directors, officers, employees or agents at the request of the
Company or its subsidiaries.
 
    BOARD OF DIRECTORS.  The Merger Agreement provides that if the Merger is
consummated, Daniel E. Vila, Alfredo L. Vila and Jose Maria Saenz Valiente will
be the directors of the Surviving Corporation.
 
    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties.
 
    APPRAISAL RIGHTS.  If the Merger is consummated, holders of Shares at the
Effective Time of the Merger will have rights pursuant to the provisions of
Article 5.12 of the TBCA ("Article 5.12") to dissent and demand appraisal of
their Shares. Under Article 5.12, dissenting stockholders who comply with the
applicable statutory procedures will be entitled to receive a judicial
determination of the fair value of their Shares (exclusive of any element of
value arising from the accomplishment or exception of the Merger) and to receive
payment of that fair value in cash, together with a fair rate of interest, if
any. The statutory procedures include notifying the Company prior to the meeting
at which the Company's stockholders vote on the Merger that the particular
stockholder intends to exercise, dissenter's rights and giving that
stockholder's address. Any judicial determination of the fair value of Shares
could be more or less than the price per Share to be paid in the Merger.
 
    The foregoing summary of Article 5.12 does not purport to be complete and is
qualified in its entirety by reference to Article 5.12. FAILURE TO FOLLOW THE
STEPS REQUIRED BY ARTICLE 5.12 FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE
LOSS OF THOSE RIGHTS.
 
    The Purchaser will not be required to complete the Merger if holders of more
than 5% of the outstanding Common Shares and 8% Preferred Shares combined
(treating each 8% Preferred Share as equal to 32 Common Shares) file objections
sufficient to preserve their right to demand appraisal of their Shares.
 
                                       20

    14. CERTAIN EFFECTS OF THE TRANSACTION.
 
    NASDAQ.  The purchase of the Shares tendered in response to the Offer will
reduce the number of Common Shares that might otherwise trade publicly and could
reduce the number of holders of Common Shares, which could adversely affect the
liquidity and market value of the remaining Common Shares held by the public.
Depending upon the number of Common Shares purchased pursuant to the Offer, the
Common Shares may no longer meet the standards for continued inclusion in the
NASDAQ Small-Cap Market, which require that an issuer have at least 200,000
publicly held shares with a market value of at least $1,000,000, held by at
least 400 shareholders or 300 shareholders of round lots. If these standards are
not met, the Common Shares might nevertheless continue to be quoted in the
over-the-counter "additional list" or in one of the "local lists," but if the
number of holders of the Common Shares falls below 300, or if the number of
publicly held Common Shares falls below 100,000 or there are not at least two
registered and active market makers for the Common Shares, the Common Shares
would no longer be "qualified" for NASDAQ reporting and NASDAQ would cease to
provide any quotations. Shares held directly or indirectly by directors,
officers or beneficial owners of more than 10% of the Common Shares (which would
include the Purchaser) are not considered as being publicly held for this
purpose. If the Common Shares are no longer eligible for NASDAQ quotation,
quotations might still be available from other sources. The extent of the public
market for the Shares and the availability of quotations would, however, depend
on the remaining number of holders of Common Shares, the interest of securities
firms in maintaining a market in the Common Shares, the possible termination of
registration under the Exchange Act, as described below, and other factors.
According to the Company, as of November 14, 1997, there were approximately 336
holders of record of Common Shares and approximately 1,460 beneficial owners of
Common Shares and as of December 5, 1997, there were 19,223,456 Common Shares
outstanding, of which 6,006,006 were owned by the Purchaser.
 
    EXCHANGE ACT REGISTRATION.  The Common Shares are currently registered under
the Exchange Act. That registration may be terminated upon application of the
Company to the Securities and Exchange Commission if the Common Shares are not
listed on a national securities exchange or quoted on NASDAQ and there are fewer
than 300 record holders of the Common Shares. The termination of registration of
the Common Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to holders of Common Shares
and to the Commission and would make certain provisions of the Exchange Act,
such as the short-swing profit recovery provisions of Section 16(b) of the
Exchange Act, the requirement of furnishing a proxy statement in connection with
stockholders' meetings pursuant to Section 14(a) of the Exchange Act, and the
requirements of Rule 13e-3 under the Exchange Act with respect to
"going-private" transactions, no longer applicable to the Company. See Section
16. In addition, "affiliates" of the Company and persons holding "restricted
securities" of the Company may be deprived of the ability to dispose of those
securities pursuant to Rule 144 under the Securities Act. If registration of the
Common Shares under the Exchange Act were terminated, the Common Shares would no
longer be eligible for quotation on NASDAQ. The Purchaser intends to seek to
cause the Company to make an application for termination of registration of the
Common Shares under the Exchange Act as soon after consummation of the Offer as
the requirements for termination of the registration of the Common Shares are
met. As a result, the Purchaser may be able to give the required stockholder
approval of the Merger (if stockholder approval is required) without the
Company's sending a proxy statement or an information statement to its
stockholders.
 
    15. DIVIDENDS AND DISTRIBUTIONS.  The Merger Agreement prohibits the Company
from paying any dividends or making other distributions with regard to its
Common Shares or its 8% Preferred Shares (other than regularly scheduled
dividends with regard to the 8% Preferred Shares), or from issuing any shares,
until the Effective Time of the Merger.

    16. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.
 
    GENERAL.  Except as otherwise disclosed in this Offer to Purchase, based on
the Company's representations and warranties in the Merger Agreement and a
review of publicly available filings by the Company with the Commission, the
Purchaser is not aware of (i) any license or regulatory permit that appears to
be material to the business of the Company and its subsidiaries, taken as a
whole, that might be adversely affected by the acquisition of Shares by the
Purchaser pursuant to the Offer or the Merger or (ii) any approval or other
action by any governmental, administrative or regulatory agency or authority,
domestic or foreign, that would be required for the acquisition or ownership of
Shares by the Purchaser, other than approvals by an Argentine governmental
authority which, although required as a pre-requisite to changes of control of
Argentine cable system operators, customarily are not given until after the
changes of control have taken place (and are not a condition to the Offer or the
Merger). Should any such approval or other action be required, the Purchaser
currently contemplates that the approval or action would be sought. It is
possible that any such approval or action, if needed, would not be obtained.
 
    GOING PRIVATE TRANSACTIONS.  The Commission has adopted Rule 13e-3 under the
Exchange Act, which is applicable to certain "going private" transactions. The
Offeror does not believe that Rule 13e-3 will be applicable to the Merger unless
the Merger is consummated more than one year after the termination of the Offer.
If applicable, Rule 13e-3 requires, among other things, that certain financial
information concerning the fairness of the Merger and the consideration offered
to minority stockholders in the Merger be filed with the Commission and
disclosed to stockholders prior to the consummation of the Merger.
 
    ANTITRUST COMPLIANCE.  Prior to the Stock Purchase, the Company and Parent
made a filing with the United States Federal Trade Commission (the "FTC") under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"). The
HSR Act requires that, before an acquisition involving companies which exceed
specified sizes can take place, information must be provided to the FTC and to
the Antitrust Division of the United States Department of Justice, and specified
waiting periods must expire or be terminated by the FTC or the Antitrust
Division.
 
    The required notification under the HSR Act was filed, and the waiting
period was terminated, before the Stock Purchase. That filing contemplated a
possible acquisition by Parent of all the stock of the Company. Therefore, no
further filing or waiting period will be required with regard to the Offer or
the Merger.
 
    STATE TAKEOVER STATUTES.  The Company is incorporated under the laws of
Texas. Effective September 1, 1997, a new Part Thirteen of the Texas Business
Corporation Act (the "Texas Business Combination Law") prohibits a public
corporation organized under Texas law, or its majority owned subsidiaries, from
engaging in a transaction with a person who acquires 20% or more of the
corporation's outstanding voting stock or its affiliates, for three years after
the person acquires that 20% or greater interest, share exchange, sale of
significant assets, issuance of shares, liquidation of the Corporation pursuant
to an agreement with the 20% or greater shareholder, reclassification of the
securities of the Corporation which increases the portion of the stock of any
class or series owned by the 20% or greater stockholder or the receipt by the
20% or greater stockholder of loans or similar financial assistance. The three
year ban does not apply, however, if the proposed transaction with the 20% or
greater stockholder, or the transaction by which the person became a 20% or
greater stockholder, is approved by the board of directors of the corporation
before the person becomes a 20% or greater stockholder. Because the Board of the
Company approved the Stock Purchase (the transaction by which the Purchaser, and
indirectly Parent, became a 20% or greater stockholder of the Company) before it
took place, the Texas Business Combination Law will not apply to the Purchaser
or Parent.
 
    A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal
 
                                       22
<PAGE>
executive offices or principal places of business, or whose business operations
otherwise have substantial economic effects, in such states. In 1982, in EDGAR
V. MITE CORP., the Supreme Court of the United States invalidated on
constitutional grounds the Illinois Business Takeover Statute, which, as a
matter of state securities law, made takeovers of corporations meeting certain
requirements more difficult. However, in 1987, in CTS CORP. V. DYNAMICS CORP. OF
AMERICA, the Supreme Court held that the State of Indiana may, as a matter of
corporate law, and, in particular, with respect to those aspects of corporate
law concerning corporate governance, constitutionally disqualify a potential
acquiror from voting on the affairs of a target corporation without the prior
approval of the remaining stockholders. The state law before the Supreme Court
was by its terms applicable only to corporations that had a substantial number
of stockholders in the state and were incorporated there.
 
    17. FEES AND EXPENSES.  Except as set forth below, neither Parent nor the
Purchaser will pay any fees or commissions to any broker, dealer or other person
for soliciting tenders of Shares pursuant to the Offer.
 
    The Purchaser has retained Furman Selz LLC and ING Baring (U.S.) Securities,
Inc. to act as Dealer Managers in connection with the Offer. Furman Selz LLC and
ING Baring (U.S.) Securities, Inc. each will receive a fee of $125,000 for their
services as Dealer Managers in connection with the Offer. The Purchaser has also
agreed to reimburse Furman Selz LLC and ING Baring (U.S.) Securities, Inc. for
certain out-of pocket expenses incurred in connection with the Offer (excluding
certain fees and disbursements of their legal counsel) and to indemnify Furman
Selz LLC and ING Baring (U.S.) Securities, Inc. against certain liabilities in
connection with the Offer, including liabilities under the federal securities
laws.
 
    The Purchaser has retained Morrow & Co., Inc. to act as the Information
Agent in connection with the Offer. The Information Agent may contact holders of
Shares by mail, telephone, facsimile, telegraph and personal interviews and may
request brokers, dealers and other nominee stockholders to forward materials
relating to the Offer to beneficial owners of Shares. The Information Agent will
receive reasonable and customary compensation together with reimbursement for
its reasonable out-of-pocket expenses and will be indemnified against certain
liabilities and expenses, including certain liabilities under the federal
securities laws.
 
    In addition, The Bank of New York has been retained as the Depositary. The
Depositary has not been retained to make solicitations or recommendations in its
role as Depositary. The Depositary will receive reasonable and customary
compensation for its services, will be reimbursed for certain reasonable out-of-
pocket expenses and will be indemnified against certain liabilities and
expenses. Brokers, dealers, commercial banks and trust companies will be
reimbursed by the Purchaser for customary mailing and handling expenses incurred
by them in forwarding offering material to their customers.
 
    18. MISCELLANEOUS.  The Purchaser is not aware of any jurisdiction where the
making of the Offer is prohibited by any administrative or judicial action or
pursuant to any state statute. If the Purchaser becomes aware of any state
statute prohibiting the making of the Offer or the acceptance of the Shares
which are tendered in response to the Offer, the Purchaser will make a good
faith effort to comply with that state statute. If, after a good faith effort
the Purchaser cannot comply with any such state statute, the Offer will not be
made to (nor will tenders be accepted from or on behalf of) the holders of
Shares in such state. In any jurisdiction where the securities, Blue Sky or
other laws require the Offer to be made by a licensed broker or dealer, the
Offer will be deemed to be made on behalf of the Purchaser by the Dealer
Managers or one or more registered brokers or dealers which are licensed under
the laws of that jurisdiction.
 
    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER NOT CONTAINED IN THIS OFFER TO
PURCHASE OR IN THE LETTER OF TRANSMITTAL, AND IF GIVEN OR MADE, THAT INFORMATION
OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

designees, and each of them, the attorneys-in-fact and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney-in-fact and proxy or his or its substitute, in his or its
sole discretion, deems proper, and otherwise act (including acting by written

Letter of Transmittal which have been accepted for payment by the Purchaser
prior to the time of the vote or action (and any other Shares or securities
issued in respect of those Shares after December 8, 1997). This proxy is

deposit by the Purchaser with the Depositary of the purchase price for the
Shares to which it relates, and acceptance of those Shares for payment, in

proxies granted by the undersigned with regard to those Shares (and any such
other Shares or other securities) and the undersigned will not give any
subsequent proxies with respect to those Shares.

and authority to tender, sell, assign and transfer the Shares tendered by this

accepted for payment by the Purchaser, the Purchaser will acquire good and
unencumbered titled to the Shares (and any such other Shares or securities),
free and clear of all liens, restrictions, charges, encumbrances or adverse
claims. The undersigned, upon request, will execute and deliver any additional
documents deemed by the Depositary or the Purchaser to be necessary or desirable
to complete the sale, assignment and transfer of the Shares tendered by this
Letter of Transmittal (and any such other Shares or other securities) to the
Purchaser.
 
    The authority conferred in this Letter of Transmittal will not be affected
by, and will survive, the death or incapacity of the undersigned, and any
obligation of the undersigned under this Letter of Transmittal or otherwise
resulting from the tender of the Shares to which this Letter of Transmittal
relates will be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned. Except as stated in
the Offer to Purchase, the tender made by this Letter of Transmittal is
irrevocable.
 
    The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 3 of the Offer to Purchase and in the
instructions to this Letter of Transmittal will constitute a binding agreement
between the undersigned and the Purchaser upon the terms and subject to the
conditions of the Offer.

Transmittal or (ii) if those Shares are tendered for the account of a member
firm of a registered national securities exchange or a member of the National

"Eligible Institutions"). In all other cases, all signatures on this Letter of
Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.
 
    2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES. This Letter of
Transmittal is to be completed by stockholders either if certificates are being
forwarded with it or if tenders of Shares are to be made in accordance with the
procedures for delivery by book-entry transfer set forth in Section 3 of the
Offer to Purchase. Certificates for all physically tendered Shares, or a
Book-Entry Confirmation confirming book-entry transfer of Shares to an account
of the Depositary, as the case may be, together with a properly completed and
duly executed Letter of Transmittal (or facsimile of one) and any other
documents required by this Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth above on or prior to the Expiration
Date (as defined in Section 1 of the Offer to Purchase). Stockholders whose
certificates for Shares are not immediately available, or who cannot deliver
Book-Entry Confirmation of book entry transfer of the Shares to the Depositary
on or prior to the Expiration Date may tender their Shares by properly
completing and executing a Notice of Guaranteed Delivery in accordance with the
guaranteed delivery procedure described in Section 3 of the Offer to Purchase.
Pursuant to that procedure, (i) the tender must be made by or through an
Eligible Institution, (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form provided by the Purchaser, must
be received by the Depositary prior to the Expiration Date and (iii) the

EXCEPT AS OTHERWISE PROVIDED IN THIS INSTRUCTION 2, THE DELIVERY WILL BE DEEMED
MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
 
    No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution of
this Letter of Transmittal (or a facsimile of it), waive any right to receive
any notice of the acceptance of their Shares for payment.

of Transmittal.

transfer). If fewer than all the Shares evidenced by a certificate are to be

entitled "Number of Shares Tendered." In such case, new certificate(s) for the
remainder of the Shares that were evidenced by your old certificate(s) will be
sent to you, unless otherwise provided in the appropriate box on this Letter of
Transmittal, as soon as practicable after the Expiration Date. All Shares
represented by certificates delivered to the Depositary will be deemed to have

being tendered, the signature(s) must correspond exactly with the name(s) as
written on the face of the certificate(s), without any alteration, enlargement
or change whatsoever.

owners, all the owners must sign this Letter of Transmittal.
 
    IF TENDERED SHARES ARE REGISTERED IN DIFFERENT NAMES ON DIFFERENT
CERTIFICATES, IT WILL BE NECESSARY TO COMPLETE, SIGN AND SUBMIT AS MANY SEPARATE
LETTERS OF TRANSMITTAL AS THERE ARE DIFFERENT REGISTRATIONS ON CERTIFICATES.
<PAGE>
    If this Letter of Transmittal or any certificates or stock powers are signed
by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
that person should so indicate when signing, and submit evidence satisfactory to
the Purchaser of the person's authority so to act.
 
    When this Letter of Transmittal is signed by the registered owner(s) of the
Shares being tendered, no endorsements of certificates or separate stock powers
are required, unless payment or certificates for Shares which are not tendered
or purchased are to be issued to a person other than the registered owner(s), in
which case, endorsements of certificates or separate stock powers are required
and signatures on those certificates or stock powers must be guaranteed by an
Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Shares being tendered, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered owner(s) appear on the certificates.
Signatures on the certificates or stock powers must be guaranteed by an Eligible
Institution.
 
    6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale to it of Shares it purchases pursuant to the Offer. If
payment of the purchase price is to be made to, or if certificates for Shares
which are not tendered or are not purchased are to be registered in the name of,
any person other than the registered holder, or if tendered certificates are
registered in the name of anyone other than the person(s) signing this Letter of
Transmittal, the amount of any stock transfer taxes payable on account of the
transfer to another person (whether imposed on the registered holder or on the
other person) will be deducted from the purchase price unless satisfactory
evidence of the payment of, or an exemption from the need to pay, stock transfer
taxes is submitted.
 
    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES SUBMITTED WITH THIS LETTER
OF TRANSMITTAL.
 
    7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check or certificates for
unpurchased Shares are to be issued in the name of a person other than the
signer of this Letter of Transmittal, or if a check is to be sent or
certificates are to be returned to someone other than the signer of this Letter
of Transmittal or to an address other than the signer's address shown above, the
appropriate boxes on this Letter of Transmittal must be completed. Stockholders
tendering Shares by book-entry transfer may request that any Shares which are
not purchased be credited to an account maintained at the Book-Entry Facility
which the stockholder designates. If no instructions are given, Shares tendered
by book-entry transfer which are not purchased will be returned by crediting the
account at the Book-Entry Facility designated above.

Transmittal may be obtained from, the Information Agent or the Dealer Managers
at their respective addresses set forth below or from your broker, dealer,

Substitute Form W-9 which is provided under "Important Tax Information" below,
and to indicate that the stockholder is not subject to backup withholding by
checking the box in Part 2 of the Substitute Form W-9. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31% Federal income tax withholding from the payment of the purchase price. The
box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a number or intends to
apply for a number in the near future. If the box in Part 3 is checked and the
Depositary is not provided with a TIN within 60 days, the Depositary will
withhold 31% from all payments of the purchase price to be made after expiration
of that 60 day period until a TIN is provided to the Depositary.

                           IMPORTANT TAX INFORMATION
 
    Under Federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary with the
stockholder's correct TIN on Substitute Form W-9 below. If the stockholder is an
individual, the TIN is his or her social security number. If the Depositary is
not provided with the correct TIN, the stockholder may be subject, among other
things, to penalties imposed by the Internal Revenue Service. In addition,
payments that are made to the stockholder with respect to Shares purchased
pursuant to the Offer may be subject to backup withholding.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that individual must submit a statement, signed under penalties of
perjury, attesting to the individual's exempt status. A form of statement may be
obtained from the Depositary. See the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional
instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of the stockholder's correct TIN by completing
the form below certifying that the TIN provided on the Substitute Form W-9 is
correct (or that the stockholder is awaiting a TIN).
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The stockholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares. If
the Shares being tendered are in more than one name or are not in the name of
the actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidelines on which
number to report.

Gentlemen:
 
    The undersigned hereby tenders to Tescorp Acquisition Corporation (the
"Purchaser"), a Delaware corporation, the shares of Series 1995 8% Convertible
Preferred Stock (the "Shares"), of Tescorp, Inc. (the "Company"), a Texas
corporation, listed above, in response to the Purchaser's offer to purchase all
outstanding Shares at a price of $144 plus accrued dividends from the last date
on which dividends were paid prior to the expiration of this Offer (defined
below) per Share, net to the sellers in cash, upon the terms and subject to the
conditions set forth in the Offer to Purchase dated December 8, 1997 (the "Offer
to Purchase"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal (which, together with the Offer to Purchase, constitutes the
"Offer").
 
    Subject to, and effective upon, acceptance of the Shares tendered with this
Letter of Transmittal for payment in accordance with the Offer, the undersigned
hereby sells, assigns, and transfers to, or upon the order of, the Purchaser all
right, title and interest in and to all the Shares that are being tendered with
this Letter of Transmittal (and any other Shares or other securities issued or
issuable in respect of those Shares after December 8, 1997) and irrevocably
constitutes and appoints the Depositary the true and lawful agent and
attorney-in-fact of the undersigned with respect to those Shares (and any such
other Shares or securities) with full power of substitution, (that power of
attorney being an irrevocable power coupled with an interest) to (a) deliver
certificates for the Shares (and any such other Shares or securities) or
transfer ownership of the Shares (and any such other Shares or securities) on
the account books maintained by the Book-Entry Facility, together in either case
with all accompanying evidences of transfer and authenticity, to or upon the
order of the Purchaser upon receipt by the Depositary, as the undersigned's
agent, of the purchase price (adjusted, if appropriate, as provided in the Offer
to Purchase), (b) present those Shares (and any such other Shares or securities)
for transfer on the books of the Company and (c) otherwise exercise all rights
of beneficial ownership of the Shares (and any such other Shares or securities),
all in accordance with the terms of the Offer.
 
    The undersigned irrevocably appoints the Purchaser, its officers and its
designees, and each of them, the attorneys-in-fact and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney-in-fact and proxy or his or its substitute, in his or its
sole discretion deems proper, and otherwise act (including acting by written
consent without a meeting) with respect to, all the Shares tendered by this
Letter of Transmittal which have been accepted for payment by the Purchaser
prior to the time of the vote or action (and any other Shares or securities
issued in respect of those Shares after December 8, 1997). This proxy is
irrevocable and is granted in consideration of, and is effective upon, the
deposit by the Purchaser with the Depositary of the purchase price for the
Shares to which it relates, and acceptance of those Shares for payment, in
accordance with the Offer. That acceptance for payment will revoke all prior
proxies granted by the undersigned with regard to those Shares (and any such
other Shares or other securities) and the undersigned will not give any
subsequent proxies with respect to those Shares.
 
    The undersigned represents and warrants that the undersigned has full power
and authority to tender, sell, assign and transfer the Shares tendered by this
Letter of Transmittal (and any other Shares or other securities issued in
respect of those Shares after December 8, 1997) and that, when those Shares are
accepted for payment by the Purchaser, the Purchaser will acquire good and
unencumbered titled to the Shares (and any such other Shares or securities),
free and clear of all liens, restrictions, charges, encumbrances or adverse
claims. The undersigned, upon request, will execute and deliver any additional
documents deemed by the Depositary or the Purchaser to be necessary or desirable
to complete the sale, assignment and transfer of the Shares tendered by this
Letter of Transmittal (and any such other Shares or other securities) to the
Purchaser.
 
    The authority conferred in this Letter of Transmittal will not be affected
by, and will survive, the death or incapacity of the undersigned, and any
obligation of the undersigned under this Letter of Transmittal or otherwise
resulting from the tender of the Shares to which this Letter of Transmittal
relates will be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned. Except as stated in
the Offer to Purchase, the tender made by this Letter of Transmittal is
irrevocable.
 
    The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 3 of the Offer to Purchase and in the
instructions to this Letter of Transmittal will constitute a binding agreement
between the undersigned and the Purchaser upon the terms and subject to the
conditions of the Offer.
<PAGE>
    Unless otherwise indicated in the box below captioned "Special Payment
Instructions," please issue the check for the purchase price of the Shares
tendered by this Letter of Transmittal, and cause any Shares represented by
certificates accompanying this Letter of Transmittal which are not being
tendered, or are not accepted for payment, in the name(s) of the undersigned.
Similarly, unless otherwise indicated in the box below captioned "Special
Delivery Instructions," please mail the check for the purchase price and deliver
certificates representing any Shares which are not being tendered or are not
accepted for payment (and accompanying documents, as appropriate) to the
undersigned at the address shown below the undersigned's signature. If both the

any Shares which are not being tendered, or are not accepted for payment, in the
name of, and deliver the check and certificates, or confirmation of transfer of

Instructions." The undersigned recognizes that the Purchaser has no obligation
pursuant to the Special Payment Instructions or otherwise to transfer any
tendered Shares which are not accepted for payment from the name of the
registered holder of the Shares to the name of another person.

that person should so indicate when signing, and submit evidence satisfactory to
the Purchaser of the person's authority so to act.

registered in the name of anyone other than the person(s) signing this Letter of
Transmittal, the amount of any stock transfer taxes payable on account of the
transfer to another person (whether imposed on the registered holder or on the
other person) will be deducted from the purchase price unless satisfactory
evidence of the payment of, or an exemption from the need to pay, stock transfer
taxes is submitted.
 
    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES SUBMITTED WITH THIS LETTER
OF TRANSMITTAL.
 
    7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check or certificates for
unpurchased Shares are to be issued in the name of a person other than the
signer of this Letter of Transmittal, or if a check is to be sent or
certificates are to be returned to someone other than the signer of this Letter
of Transmittal or to an address other than the signer's address shown above, the
appropriate boxes on this Letter of Transmittal must be completed. Stockholders
tendering Shares by book-entry transfer may request that any Shares which are
not purchased be credited to an account maintained at the Book-Entry Facility
which the stockholder designates. If no instructions are given, Shares tendered

Substitute Form W-9 which is provided under "Important Tax Information" below,
and to indicate that the stockholder is not subject to backup withholding by
checking the box in Part 2 of the Substitute Form W-9. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31% Federal income tax withholding from the payment of the purchase price. The
box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a number or intends to
apply for a number in the near future. If the box in Part 3 is checked and the
Depositary is not provided with a TIN within 60 days, the Depositary will
withhold 31% from all payments of the purchase price to be made after expiration
of that 60 day period until a TIN is provided to the Depositary.

CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED
DOCUMENTS, OR A NOTICE OF GUARANTEED DELIVERY, MUST BE RECEIVED BY THE

                           IMPORTANT TAX INFORMATION
 
    Under Federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary with the
stockholder's correct TIN on Substitute Form W-9 below. If the stockholder is an
individual, the TIN is his or her social security number. If the Depositary is
not provided with the correct TIN, the stockholder may be subject, among other
things, to penalties imposed by the Internal Revenue Service. In addition,
payments that are made to the stockholder with respect to Shares purchased
pursuant to the Offer may be subject to backup withholding.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that individual must submit a statement, signed under penalties of
perjury, attesting to the individual's exempt status. A form of statement may be
obtained from the Depositary. See the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional
instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of the stockholder's correct TIN by completing
the form below certifying that the TIN provided on the Substitute Form W-9 is
correct (or that the stockholder is awaiting a TIN).
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The stockholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares. If
the Shares being tendered are in more than one name or are not in the name of
the actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidelines on which
number to report.

    The Board of Directors of the Company (a) has approved the Offer and the
Merger (as defined in the Offer to Purchase) which will follow the Offer if the
Offer is successfully completed and the shareholders of the Company approve the
Merger, (2) has determined that the terms of the Offer and the Merger are fair
to and in the best interests of the Company's stockholders, and (3) recommends
that the holders of the Common Shares and 8% Preferred Shares tender their
Shares in response to the Offer.
 
    The Offer is being made pursuant to an Amended Stock Purchase and Merger
Agreement dated as of November 26, 1997 (the "Merger Agreement"), between the
Purchaser and the Company. The Merger Agreement provides that, among other
things, as soon as practicable after the purchase of shares pursuant to the
Offer and the satisfaction or waiver of the other conditions set forth in the
Merger Agreement the Purchaser will be merged with and into the Company (the
"Merger"). At the effective time of the Merger (the "Effective Time"), each
Common Share which is outstanding immediately before the Effective Time, other
than shares owned by the Purchaser, will be converted into and become the right
to receive $4.50 in cash, or any higher price per share paid with regard to
Common Shares tendered in response to the Offer. At the Effective Time, each 8%
Preferred Share which is outstanding immediately before the Effective Time will
be converted into and become the right to receive in cash $144 per share plus
dividends accrued up to the Expiration Date of the Offer (except that if a
dividend is paid with regard to the 8% Preferred Shares between the Expiration
Time and the Effective Time, each 8% Preferred Share will be converted into and
become the right to receive $144 in cash without regard to any accrued but
unpaid dividends). At the Effective Time, each Common Share or 8% Preferred
Share held by the Purchaser or by any direct or indirect subsidiary of the
Company immediately before the Effective Time will be cancelled and no payment
will be made with respect to those Shares.
 
    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of certificates
evidencing such Shares or a confirmation of a book-entry transfer of such Shares
into the Depositary's account at the Book-Entry Transfer Facility (as defined in
the Offer to Purchase), a Letter of Transmittal (or facsimile thereof) properly
completed and duly executed, or an Agent's Message (as defined in the Offer to
Purchase), and any other required documents in accordance with the instructions
contained in the Letter of Transmittal.
 
    If a holder of Shares wishes to tender Shares, but cannot deliver such
holder's certificates or other required documents, or cannot comply with the
procedure for book-entry transfer, prior to the expiration of the Offer, a
tender of Shares may be effected by following the guaranteed delivery procedure
described in Section 3 of the Offer to Purchase.
 
    The Purchaser will not pay any commissions or fees to any broker, dealer or
other person (other than the Dealer Managers and the Information Agent, as
described in the Offer) in connection with the
 
                                       2

solicitation of tenders of Shares pursuant to the Offer. However, the Purchaser
will reimburse you for customary mailing and handling expenses incurred by you
in forwarding any of the enclosed materials to your clients. The Purchaser will
pay or cause to be paid any stock transfer taxes payable with respect to the
transfer of Shares to it, except as otherwise provided in Instruction 6 of the
Letter of Transmittal.
 
    Any inquiries you may have with respect to the Offer and requests for
additional copies of the enclosed materials should be addressed to the Dealer
Managers or the Information Agent at their respective addresses and telephone
numbers set forth on the back cover of the Offer to Purchase.
 
                                          Very truly yours,

PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payors
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payors must generally withhold 31% of taxable interest,
dividend, and certain other payments to a payee who does not furnish a taxpayer
identification number to a payor. Certain penalties may also apply.
 
PENALTIES
 
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your correct taxpayer identification number to a requester, you are
subject to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
 
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
 
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
 
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

    The Offer is conditioned upon (1) there being validly tendered and not
withdrawn prior to the expiration of the Offer a number of Common Shares of the
Company, which, when added to the Common Shares already owned by the Purchaser,
constitutes more than two-thirds of the total number of outstanding Common
Shares, (2) there being validly tendered and not withdrawn prior to the
expiration of the Offer a number of 8% Preferred Shares which, when added to any
8% Preferred Shares already owned by the Purchaser, constitutes more than
two-thirds of the total number of outstanding 8% Preferred Shares and (3)
satisfaction of certain other conditions.

    The Offer is being made in accordance with an Amended Stock Purchase and
Merger Agreement (the "Merger Agreement"), dated November 26, 1997, between the
Company and the Purchaser which amends and restates a Stock Purchase and Merger
Agreement dated September 16, 1997 between the Company and the Purchaser.  The
Merger Agreement provides that, among other things, as soon as practicable after
the purchase of shares pursuant to the Offer and the satisfaction or waiver of
the other conditions set forth in the Merger Agreement the Purchaser will be
merged with and into the Company (the "Merger").  At the effective time of the
Merger (the "Effective Time"), each Common Share which is outstanding
immediately before the Effective Time, other than shares owned by the Purchaser,
will be converted into and become the right to receive $4.50 in cash, or any
higher price per share paid with regard to Common Shares tendered in response to
the Offer.  At the Effective Time, each 8% Preferred Share which is outstanding
immediately before the Effective Time will be converted into and become the
right to receive in cash $144 per share plus dividends accrued up to the
Expiration Date of the Offer (except that if a dividend is paid with regard to
the 8% Preferred Shares between the Expiration Time and the Effective Time, each
8% Preferred Share will be converted into and become the right to receive
$144.00 in cash without regard to any accrued but unpaid dividends).  At the
Effective Time, each Common Share or 8% Preferred Share held by the Purchaser or
by any direct or indirect subsidiary of the Company immediately before the
Effective Time will be cancelled and no payment will be made with respect to
those Shares.

    For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, the Shares which are validly tendered and
not withdrawn, when the Purchaser gives oral or written notice to The Bank of
New York (the "Depositary") of the Purchaser's acceptance of those Shares for
payment.  Payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the Purchaser
and transmitting payment to the tendering stockholders.  Payment for Shares
accepted for payment pursuant to the Offer will be made only after timely
receipt by the Depositary of (i) certificates for the Shares or timely
confirmation of a book-entry transfer of the Shares into the Depositary's
account at the Book-Entry Transfer Facility (as defined in the Offer to
Purchase) in accordance with the procedures described in the Offer to Purchase,
(ii) a properly completed and duly executed Letter of Transmittal (or facsimile
of one), with any required signature guarantees, or, in the case of a book-entry
transfer, an Agent's Message (as defined in the Offer to Purchase) and (iii) any
other documents required by the Letter of Transmittal.

    If any of the conditions set forth in the Offer to Purchase that relate to
the Purchaser's obligations to purchase the Shares are not satisfied by 12:00
Midnight, New York City Time, on January 9, 1998 (or any other time set as the
Expiration Date), the Purchaser may, subject to the terms of the Merger
Agreement, (i) extend the Offer and, subject to applicable withdrawal rights,
retain all tendered Shares until the expiration of the Offer as so extended,
(ii) subject to complying with applicable rules and regulations of the
Securities and Exchange Commission, accept for payment all Shares which are
tendered and not extend the Offer, or (iii) terminate the Offer and not accept
for payment any Shares and return all tendered Shares to the tendering
stockholders.  The term "Expiration Date" means 12:00 Midnight, New York City
Time, on January 9, 1998, unless the Purchaser extends the time during which the
Offer is open, in which event the term "Expiration Date" will mean the latest
time and date at which the Offer, as so extended, will expire.

    Subject to the limitations set forth in the Offer and the Merger Agreement,
the Purchaser reserves the right (but will not be obligated), at any time or
from time to time in its sole discretion, to extend the period during which the
Offer is open by giving oral or written notice of the extension to the
Depositary and by making a public announcement of the extension.  The Purchaser
will make a public announcement of any extension of the period during which the
Offer is open not later than 9:00 a.m., New York City Time, on the business day
after the previously scheduled Expiration Date.  During any extension, all
Shares previously tendered and not withdrawn will remain tendered in response to
the Offer, subject to the rights of a tendering stockholder to withdraw tendered
Shares.

irrevocable, except that Shares tendered in response to the Offer may be
withdrawn at any time prior to the Expiration Date, and, unless they have been
accepted for payment, may also be withdrawn at any time after February 9, 1998.
For a withdrawal to be effective, a written or facsimile transmission of a
notice of withdrawal must be timely received by the Depositary at one of its
addresses set forth on the back cover of the Offer to Purchase.  A notice of
withdrawal must specify the name of the person who tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and (if share certificates have
been tendered) the name of the registered holder if different from the name of
the person who tendered the Shares.  If certificates for Shares to be withdrawn
have been delivered or otherwise identified to the Depositary, then prior to the
release of those certificates, the serial numbers shown on the particular
certificates to be withdrawn must be submitted to the Depositary and, unless the
Shares have been tendered for the account of an Eligible Institution (as defined
in the Offer to Purchase), the signatures on the notice of withdrawal must be
guaranteed by an Eligible Institution.  If Shares have been delivered pursuant
to the procedure for book-entry transfer described in Section 3 of the Offer to
Purchase, any notice of withdrawal must also specify the name and number of the
account at the Book-Entry Transfer Facility to be credited with the withdrawn
Shares and otherwise comply with the Book-Entry Transfer Facility's procedures. 
All questions as to the form and validity (including time of receipt) of a
notice of withdrawal will be determined by the Purchaser, in its sole
discretion, and its determination will be final and binding.

14d-6 of the General Rules and Regulations under the Securities Exchange Act of
1934, as amended, is contained in the Offer to Purchase and is incorporated

FOR IMMEDIATE RELEASE

                          Supercanal, Tescorp Reach Amended
                                  Merger Agreement,
                          Supercanal Announces Tender Offer


    Mendoza, Argentina (December 5, 1997) -- Supercanal Holding S.A. announced
today that it has purchased approximately 31% of the outstanding common stock of
Tescorp, Inc. (NASDAQ:TESC) and will be making a tender offer for the remaining
Tescorp Common Stock as well as for Tescorp's Series 1995 8% Preferred Stock.

    In today's transaction, a Supercanal subsidiary purchased 6,006,006 newly
issued shares of Tescorp common stock for a total of $20 million.  A $5 million
deposit made by Supercanal in connection with the execution of an agreement in
September was credited against the purchase price.

    Supercanal, through its subsidiary, will be soliciting tenders of the
remainder of Tescorp's outstanding common stock for $4.50 per share and will be
soliciting tenders of Tescorp's outstanding Series 1995 8% Preferred Stock for
$144 per share plus an amount equal to accrued dividend.  The obligation to
accept shares which are tendered in response to that solicitation will be
subject to a number of conditions, including the condition that the tendered
shares, together with shares already owned by Supercanal, total at least two
thirds of the outstanding Tescorp common stock and two thirds of the outstanding
Tescorp 8% Preferred Stock.

    If the tender offer is completed, the Supercanal subsidiary will be merged
with Tescorp in a transaction in which Supercanal will become the sole
stockholder of the surviving corporation and the pre-merger Tescorp stockholders
(other than Supercanal and its subsidiary) will receive cash of $4.50 per share
of common stock and $144 per share of 8% Preferred Stock, plus any unpaid
dividends.

    Tescorp will be sending holders of its Series 1990 10% Preferred Stock
notice of redemption of that stock for $5 per share plus accrued and unpaid
dividends.  However, until the end of the 60 day period, holders will have the
right to convert each share of 10% Preferred Stock into 1.2531 shares of Tescorp
common stock.  Until the Supercanal tender offer expires, common stock obtained
by converting 10% Preferred Stock can be tendered for the equivalent of $5.639
per share of 10% Preferred Stock,

subject to the conditions of the tender offer being met.  Holders of 10% 
Preferred Stock who convert it after the tender offer expires will receive 
the same $5.639 per share of 10% Preferred Stock in the merger of the 
Supercanal subsidiary with Tescorp.  Holders who do not convert 10% Preferred 
Stock during the 60 day period will receive only $5 per share of 10% 
Preferred Stock.

    Documents relating to the tender offer will be sent to Tescorp stockholders
shortly.

    Daniel E. Vila, chairman and CEO of Supercanal Holding, said, "Jack Crosby,
chairman and CEO of Tescorp, and his management team have done an outstanding
job of building their company.  We are delighted with this opportunity to work
together with them on this merger.  It is part of our ongoing commitment to
build a major cable and telecommunications company that will play an important
role in the growth and development of Argentina."

    Tescorp, Inc. acquires and develops cable systems and communications
properties in Latin America concentrating on Argentina.  For the fiscal year
ended March 1997, Tescorp revenue increased 41% to $22.6 million.  The Tescorp
transaction will provide Supercanal with roughly 130,000 new subscribers
including 70,000 existing subscribers primarily in the Patagonia and Tierra del
Fuego regions and an additional 60,000 subscribers through existing purchase
options and systems available for acquisition.  Tescorp also holds a license to
provide data services to its customers.

    Supercanal Holding S.A. provides multi-channel television services via
cable, wireless and DBS technology in Argentina.  The company is the largest
multiple system operator (MSO) in Argentina operating exclusively outside the
Province of Buenos Aires.

    Argentina has Latin America's highest cable penetration rate.  The
country's 1996 per capita gross domestic product was the highest in the region.

such Purchaser has made or will make such amount available to the 
Administrative Agent on such date and the Administrative Agent may (but shall 
have no obligation to), in reliance upon such assumption, make available to 
the relevant Issuer or 

                                 21

corresponding amount forthwith upon the Administrative Agent's demand 
therefor, the Administrative Agent shall promptly notify the relevant Issuer 
or Issuers and the relevant Issuer or Issuers shall immediately pay such 
corresponding amount to the Administrative Agent. The Administrative Agent 
shall also be entitled to recover on demand from such Purchaser or the 
Issuers, as the case may be, interest on such corresponding amount in respect 
of each day from the date such corresponding amount was made available by the 
Administrative Agent to the relevant Issuer or Issuers until the date such 
corresponding amount is recovered by the Administrative Agent, at a rate per

to the Administrative Agent of acquiring overnight federal funds at the then

Issuers may have against any Purchaser as a result of any failure by such 
Purchaser to make an Advance  hereunder.

    U.S.$10,000,000 (or the equivalent).

         (b)  Notwithstanding anything contained herein to the contrary, the 
aggregate  principal amount of the Advances and the Bridge Advances for each 
of the items specified in Section 2.4(a)(i) through (vii) above shall not 
exceed the corresponding amounts specified above.

         (c)  Subject to Section 2.2(e), all Advances shall be made by the 
Purchasers pro rata on the basis of their Commitments.  It is understood that 
no Purchaser shall be responsible for any default by any other Purchaser of 
its obligation to make an Advance except to the extent set forth in Section 
2.2(e), and that each Purchaser shall be obligated to make the Advances 
provided to be made by it thereunder regardless of the failure of any other 
Purchaser to make its Advance hereunder.

         2.5  Interest.  (a) The Issuers agree to pay interest in respect of 
the unpaid principal amount of each Advance from the date the amount of such 
Advance is made available to the Issuers as provided herein until the 
maturity thereof (whether by acceleration or otherwise) at a rate per annum 
which shall, during each Interest Period applicable thereto, be equal to the 
sum of the Applicable Margin plus LIBOR for such Interest Period.

         (b)  During any period in which an Event of Default has occurred and
is continuing (whether or not the Advances are accelerated), as the result of a
default by the Issuers in the payment when due of any amount required to be paid
hereunder, the outstanding principal amount of each Advance and, to the extent
permitted by law, overdue interest in respect of the outstanding principal
amount of each Advance and any other overdue amount payable by the 

                                    23

<PAGE>

Issuers hereunder or under any other Purchase Document shall bear interest at a
rate per annum equal to the product of (i) LIBOR in effect from time to time
plus the Applicable Margin, and (ii) 1.5, in each such case with such interest
to be payable on demand.  During any period in which an Event of Default has
occurred and is continuing (but the Advances have not been accelerated), as the
result of a default by the Issuers in the due performance or observance of any
term, covenant or agreement contained in Section 8, the outstanding principal
amount of each Advance and, to the extent permitted by law, overdue interest in
respect of the outstanding principal amount of each Advance and any other
overdue amount payable by the Issuers hereunder or under any other Purchase
Document shall bear interest at a rate per annum equal to the sum of (i) LIBOR
in effect from time to time, plus (ii) the Applicable Margin, plus (ii) 2%, in
each such case with such interest to be payable on demand. 

         (c)  Accrued (and theretofore unpaid) interest shall be payable in
respect of the outstanding principal amount of each Advance on the last day of
each Interest Period applicable thereto, on any repayment or prepayment (on the
amount repaid or prepaid), at maturity (whether by acceleration or otherwise)
and, after such maturity, on demand.

         (d)  On each Interest Determination Date, the Administrative Agent
shall determine LIBOR for the Interest Period applicable to the Advances and
shall promptly notify the Issuers and the Purchasers thereof.  Each such
determination shall, absent manifest error, be final and conclusive and binding
on all parties hereto.

         2.6  Increased Costs, Illegality, etc.

         (a)  In the event that any Purchaser shall have determined (which
determination shall, absent manifest error, be final and conclusive and binding
upon all parties hereto but, with respect to clause (i) below, may be made only
by the Administrative Agent):

              (i)  on any Interest Determination Date that, by reason of any
    changes arising after the Effective Date affecting the London interbank
    Eurodollar market, adequate and fair means do not exist for ascertaining
    the applicable interest rate on the basis provided for in the definition of
    LIBOR; or
              (ii) at any time, that such Purchaser shall incur increased costs
    or reductions in the amounts received or receivable hereunder with respect
    to any Advance because of (x) any change since the Effective Date in any
    applicable Law or in the interpretation or administration thereof and
    including the introduction of any new Law, such as, for example, but not
    limited to: (A) a change in the basis of taxation of payments to any
    Purchaser of the principal of or interest on the Notes or any other amounts
    payable hereunder (except for changes in the rate of tax on, or determined
    by reference to, the net income or profits of such Purchaser pursuant to
    the laws of the jurisdiction in which it is organized or in which its
    principal office or applicable Funding Office is located or any subdivision
    thereof or therein) or (B) a change in official reserve requirements and/or
    (y) other circumstances since the Effective Date affecting such Purchaser
    or the London interbank Eurodollar market or the position of such Purchaser
    in such market; or

                                       24

<PAGE>

              (iii) at any time, that the making or continuance of any
    Advance has been made (x) unlawful by any law or governmental rule,
    regulation or order, (y) impossible by compliance by any Purchaser in good
    faith with any governmental request (whether or not having force of law) or
    (z) impracticable as a result of a contingency occurring after the
    Effective Date which materially and adversely affects the London interbank
    Eurodollar market;

then, and in any such event, such Purchaser (or the Administrative Agent, in the
case of clause (i) above) shall promptly give telephonic notice (confirmed in
writing) to the Issuers and, except in the case of clause (i) above, to the
Administrative Agent of such determination (which notice the Administrative
Agent shall promptly transmit to each of the other Purchasers).  Thereafter
(x) in the case of clause (i) above, the interest rate during the applicable
Interest Period shall be the Base Rate in effect on the applicable Interest
Determination Date plus the Applicable Margin, (y) in the case of clause (ii)
above, the Issuers shall pay to such Purchaser, upon written demand therefor,
such additional amounts (in the form of an increased rate of, or a different
method of calculating, interest or otherwise as such Purchaser in its sole
discretion shall determine) as shall be required to compensate such Purchaser
for such increased costs or reductions in amounts received or receivable
hereunder (a written notice as to the additional amounts owed to such Purchaser,
showing the basis for the calculation thereof, submitted to the Issuers by such
Purchaser shall, absent manifest error, be final and conclusive and binding on
all the parties hereto) and (z) in the case of clause (iii) above, the Issuers
shall take one of the actions specified in Section 2.6(b) as promptly as
possible and, in any event, within the time period required by law.

         (b)  At any time that any Advance is affected by the circumstances
described in Section 2.6(a) (iii), the Issuers shall either (x) if the affected
Advance is then being made initially, cancel the respective Advance (subject,
however, to Section 2.7), or (y) if the affected Advance is then outstanding,
upon at least five Business Days' written notice to the Administrative Agent,
repay the Advance of the affected Purchaser, provided that, if more than one
Purchaser is affected at any time, then all affected Purchasers must be treated
the same pursuant to this Section 2.6(b).

         (c)  If any Purchaser determines at any time that the introduction or
implementation of, or any change in, any applicable Law after the Effective
Date, concerning capital adequacy, or any change in interpretation or
administration thereof after the Effective Date by any Governmental Authority,
will have the effect of increasing the amount of capital required or expected to
be maintained by such Purchaser based on the existence of such Purchaser's
Commitment hereunder or its obligations hereunder, then the Issuers shall pay to
such Purchaser, within 15 Business Days of its written demand therefor, such
additional amounts as shall be required to compensate such Purchaser for the
increased cost to such Purchaser as a result of such increase of capital.  In
determining such additional amounts, each Purchaser will act reasonably and in
good faith and will use averaging and attribution methods which are reasonable,
provided that such Purchaser's determination of compensation owing under this
Section 2.6 shall, absent manifest error, be final and conclusive and binding on
all the parties hereto.  Each Purchaser, upon determining that any additional
amounts will be payable pursuant

                                       25

<PAGE>

to this Section 2.6, will give prompt written notice thereof to the Issuers, 
which notice shall show the basis for calculation of such additional amounts, 
and the failure to give any such notice shall not release the Issuers' 
obligations to pay additional amounts pursuant to this Section 2.6.

         (d)  At any time that any Advance is affected by the circumstances
described in Sections 2.6(a)(ii) or 2.6(c), the Issuers shall have the right
(subject, however, to Section 2.7), upon at least five Business Days' written
notice to the Administrative Agent, to prepay the Advance of the affected
Purchaser, provided that, if more than one Purchaser is affected at any time,
then all affected Purchasers must be treated the same pursuant to this Section
2.6(d).

         2.7  Compensation.  The Issuers shall compensate each Purchaser, upon
its written request (which request shall set forth the basis for requesting such
compensation and shall, absent manifest error, be final and conclusive and
binding on all the parties hereto), for all reasonable losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Purchaser to fund its Advances) which such Purchaser may
sustain: (i) if for any reason (other than a default by such Purchaser or the
Administrative Agent) any Funding of Advances does not occur on the date
specified therefor in a Notice of Funding (whether or not withdrawn by the
Issuer); (ii) if any repayment (including any prepayment made pursuant to
Section 4) of its Advances occurs on a date which is not the last day of an
Interest Period with respect thereto, or (iii) as a consequence of (x) any other
default by the Issuers to repay the Advances when required by the terms of this
Agreement or the Notes or (y) any actions taken pursuant to Sections 2.6(b) or
(d).

         Section 3. Commitment Fee; Additional Fees; Reduction of Total
Commitment.

         3.1  Commitment Fee.  The Issuers agree to pay to the Administrative
Agent for distribution to the Purchasers a commitment commission (the
"Commitment Fee") for the period from the Effective Date until the earlier of
(i) the date that the Purchasers shall have made Advances in an aggregate
principal amount equal to the Total Commitment, or (ii) the Availability Expiry
Date (or, in either such case, such earlier date as the Total Commitment shall
have been terminated), computed at a rate equal to 1% per annum on the daily
average Unutilized Commitment.  The Commitment Fee shall be due and payable in
arrears on (x) the last Business Day of each calendar quarter, beginning on
December 31, 1997, and (y) upon the earlier of (A) the Availability Expiry Date,
and (B) such earlier date as the Total Commitment shall be terminated.

         3.2  Additional Fees.  The Issuers agree to pay to the Administrative
Agent, for its own account the fees that have been agreed to in that certain
letter dated the date hereof between Supercanal Holding and the Administrative
Agent.

         3.3  Reduction of Total Commitment.  

         (a)  If Tescorp Delaware shall not have consummated the acquisition of
the Purchased Common Stock pursuant to, and as defined in, the Tescorp Purchase
Agreement on or 

                                       26

<PAGE>

before December 31, 1997, the Total Commitment shall be reduced by an amount, 
if any, equal to the Tescorp Carryover Reduction Amount.  For purposes 
hereof, the "Tescorp Carryover Reduction Amount" shall mean the difference, 
if any, between (i) U.S.$100,000,000, and (ii) the amount of the commitment 
reduction effected pursuant to Section 3.3(a) of the Bridge Note Purchase 
Agreement, to the extent such reduction reduces the Unutilized Total 
Commitment (as defined in the Bridge Note Purchase Agreement).

         (b)  Each increase or reduction of the Total Commitment pursuant to
this Section 3.3 shall apply proportionately to the Commitment of each
Purchaser.

         3.4  Voluntary Termination of Unutilized Total Commitment.  Upon at
least five Business Days' prior notice to the Administrative Agent at its Notice
Office (which notice the Administrative Agent will promptly transmit to each of
the Purchasers), the Issuers shall have the right, without premium or penalty,
to terminate the Unutilized Total Commitment in whole or in part, in integral
multiples of U.S.$5,000,000, provided that any such termination shall apply
proportionately to reduce the Commitment of each Purchaser.

         Section 4. Prepayments; Scheduled Repayments; Payments.

         4.1  Voluntary Prepayments.  The Issuers shall have the right to
prepay the Advances, without premium or penalty, in whole or in part at any time
and from time to time after the Initial Funding Date on the following terms and
conditions: (i) the Issuers shall give the Administrative Agent at the Notice
Office at least five Business Days' prior written notice of its intent to prepay
the Notes and the amount of such prepayment (which notice the Administrative
Agent will promptly transmit to each of the Purchasers); (ii) each prepayment in
respect of any Advances shall be in an aggregate principal amount of at least
U.S.$5,000,000; (iii) prepayments of an Advance may only be made pursuant to
this Section 4.1 on the last day of an Interest Period applicable thereto,
unless the Issuers pay all amounts owing under Section 2.7 as a result of
repaying such Advance on a day other than the last day of the Interest Period
applicable thereto; (iv) each prepayment in respect of any Advances shall be
applied pro rata among such Advances in the inverse order of maturity; and (v)
the Issuers shall have provided reasonable assurances to the Administrative
Agent that the prepayment does not violate any applicable Laws of Argentina.

         4.2  Scheduled Repayments.  (a)  On the dates set forth below, the
Issuers shall repay the principal amount of the Advances, to the extent then
outstanding, as is set forth opposite such date (each such repayment, a
"Scheduled Repayment" and each such date, a "Repayment Date"), as follows:

         Repayment Date                Amount

         Final Maturity Date           U.S.$135,000,000


         (b)  If the Total Commitment is reduced pursuant to Section 3.3, or if
less than all of the Advances are funded, the Scheduled Repayments set forth
above shall be reduced by the amount of such reduction or amount not borrowed
pro rata based upon the then remaining Scheduled Repayments after giving effect
to prior reductions thereto.

         4.3  Mandatory Prepayments.

         (a)  In addition to any other mandatory prepayments pursuant to this
Section 4.3, if at any time after the Initial Funding Date any of the Issuers,
any Purchasing Agents or the Offeror receives or is entitled to receive any Net
Proceeds from any public or private sale by any such Person of debt or equity
securities (other than in connection with the Proposed IPO) of any Issuer or the
Offeror, including, without limitation, in connection with the Proposed High
Yield Debt Offering, then the Issuers shall promptly make, or cause to be made,
a mandatory prepayment of the Advances and the other Obligations in an amount
equal to the lower of (i) 100% of such Net Proceeds, and (ii) the outstanding
amount of the Advances and other Obligations; provided, however, that the
Issuers shall not be required to make any such prepayment in connection with any
sale of Stock of any Issuer which results in Net Proceeds to the Issuers of less
than U.S.$100,000 (or the equivalent thereof) in the aggregate.

         (b)  In addition to any other mandatory prepayments pursuant to this
Section 4.3, if at any time after the Initial Funding Date any of the Issuers,
any Purchasing Agents or the Offeror receives or is entitled to receive any Net
Proceeds from the Proposed IPO, then the Issuers shall promptly make, or cause
to be made, a mandatory prepayment of the Advances and the other Obligations in
an amount equal to the lower of (i) the amount of the Net Proceeds, (ii) the sum
of (x) U.S.$100,000,000, and (y) 50% of the difference between the amount of the
Net Proceeds and U.S.$100,000,000, and (iii) the outstanding amount of the
Advances and other Obligations.

         (c)  In addition to any other mandatory prepayments pursuant to this
Section 4.3, if at any time after the Initial Funding Date any of the Issuers
receives or is entitled to receive any Net Proceeds in excess of U.S.$1,000,000
(or the equivalent thereof) from the sale of any assets in any single or related
series of transactions other than in the ordinary course of business (including
any sale of Stock of any Issuer or any other Person), then the Issuers shall
promptly make a mandatory prepayment of the Advances and the other Obligations
in an amount equal to the lower of (i) 100% of such Net Proceeds (and not merely
the excess), and (ii) the outstanding amount of the Advances and other
Obligations; provided, however, that if any such sale is made by a Subsidiary of
Supercanal Holding other than a wholly-owned Subsidiary, the mandatory
prepayment shall be in an amount equal to the Net Proceeds of such sale
multiplied 

                                       28

<PAGE>

by the percentage ownership interest (direct or indirect) of Supercanal 
Holding in such Subsidiary.

         (d)  In addition to any other mandatory prepayments pursuant to this
Section 4.3, on April 30, 1999 and on April 30 of each year thereafter, the
Issuers shall make a mandatory prepayment of the Advances and the other
Obligations in an amount equal to the lower of (i) 100% of the Excess Cash Flow
for the immediately preceding calendar year, and (ii) the outstanding amount of
the Advances and other Obligations; provided, however, that if all principal,
interest and all other amounts due under the Bridge Note Purchase Agreement
shall have been fully paid on or before the first anniversary of the Effective
Date, the obligation of the Issuers to make a mandatory prepayment under this
Section 4.3(d) shall commence on April 30, 2000 and continue on each April 30
thereafter and the amount of any such mandatory prepayment shall be reduced to
an amount equal to the lower of (x) 50% of the Excess Cash Flow for the
immediately preceding calendar year, and (y) the outstanding amount of the
Advances and other Obligations.

         (e)  Each prepayment pursuant to this Section 4.3 shall be applied pro
rata among the Advances to the repayment of the principal thereof in the inverse
order of maturity.

         4.4  Method and Place of Payment.

         (a)  Except as otherwise specifically provided herein, all payments
under this Agreement or any Note shall be made to the Administrative Agent for
the account of the Purchaser or Purchasers entitled thereto not later than 12:00
Noon (New York time) on the date when due and shall be made in Dollars in
immediately available funds at the Payment Office; provided, however, that if
the Issuers are not able to so tender Dollars as a result of the adoption of a
Law, the taking of action by a Governmental Authority or the occurrence of any
other circumstance which in any such case prohibits or prevents the payment of
Dollars, the Issuers shall, during the continuance of such prohibition or
restriction, make payments hereunder and under the Notes by delivering to the
Administrative Agent, for the benefit of the Purchasers, at its own expense, an
amount of Dollar Denominated Securities which, when sold by the Administrative
Agent in the markets in which such securities are customarily traded, will
result in net proceeds to the Administrative Agent sufficient to satisfy in full
the payments due hereunder and under the Notes in respect of the Obligations. 
The Administrative Agent shall sell any such Dollar Denominated Securities
promptly, but in no event later than 30 days after delivery thereof, unless the
Issuers shall otherwise so direct in writing.  Any such delivery of Dollar
Denominated Securities shall only be deemed to constitute payment of the
applicable Obligation upon receipt by the Administrative Agent of the full
amount of Dollars due in respect thereof.

         (b)  Whenever any payment to be made hereunder or under any Note shall
be stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day and, with respect to
payments of principal, interest shall be payable at the applicable rate during
such extension.

                                       29

<PAGE>

         (c)  Any payment of principal or interest hereunder or under any Note
in respect of any Advance shall be made by the Issuer which received the
proceeds of such Advance.  Contemporaneously with any such payment, the Issuers
shall provide the Administrative Agent with evidence satisfactory to the
Administrative Agent of compliance with this Section 4.4(c).

         4.5  Net Payments.  All payments made by the Issuers hereunder or
under any Note will be made without setoff, counterclaim or other defense.  All
such payments will be made free and clear of, and without deduction or
withholding for, any present or future taxes, value-added taxes, levies,
imposts, duties, fees, assessments or other charges of whatever nature now or
hereafter imposed by any jurisdiction or by any political subdivision or taxing
authority thereof or therein (but excluding, except as provided below, any tax
imposed on or measured by the net income of a Purchaser pursuant to the laws of
the jurisdiction (or any political subdivision or taxing authority thereof or
therein) in which the principal office or Funding Office of such Purchaser is
located and any jurisdiction which would have legal power to tax the net income
of a Purchaser if such Purchaser had not made any Advance to the Issuers) and
all interest, penalties or similar liabilities with respect thereto
(collectively, "Taxes").  The Issuers shall also reimburse each Purchaser, upon
the written request of such Purchaser, for all other taxes imposed on or
measured by the net income of such Purchaser pursuant to the laws of the
jurisdiction (or any political subdivision or taxing authority thereof or
therein) in which the principal office or Funding Office of such Purchaser is
located as such Purchaser shall determine are payable by such Purchaser in
respect of amounts paid to or on behalf of such Purchaser pursuant to the
preceding sentence.  If any Taxes are so levied or imposed, the Issuers agree to
pay the full amount of such Taxes and such additional amounts as may be
necessary so that every payment of all amounts due hereunder or under any Note,
after withholding or deduction for or on account of any Taxes, will not be less
than the amount provided for herein or in such Note.  The Issuers will furnish
to the Administrative Agent within 45 days after the date the payment of any
Taxes is due pursuant to applicable Law certified copies of tax receipts
evidencing such payment by the Issuers (provided, that if any such receipts
cannot be obtained within 45 days, the Issuers will furnish such receipts as
soon as reasonably practicable).  Argentine value-added tax or any tax imposed
in replacement thereof will be invoiced directly to the Issuers by each
Purchaser which is an Argentine financial institution or whose Funding Office is
located in Argentina, and the Issuer will pay such tax directly to such
Purchaser upon receipt of any such invoice.  The Issuers will indemnify and hold
harmless each Purchaser, and reimburse such Purchaser upon its written request,
for the amount of any Taxes or other taxes described above which are levied or
imposed on and paid by such Purchaser.

         Section 5. Conditions Precedent.

         5.1  Conditions Precedent to the Initial Funding.  The obligation of

         (c)  Notice of Funding; Amount of Funding.  The Administrative Agent
shall have received a Notice of Funding with respect to the Advances to be made
on such date meeting the requirements of Section 2.2(b).  Each Advance requested
in such Notice of Funding shall not exceed the Permitted Funding Amount with
respect to such Advance, and the sum of (i) aggregate amount of the Advances
requested in such Notice of Funding, and (ii) the aggregate amount of all
Advances outstanding under the Notes, shall not exceed the product of (x) 5.25,
and (y) the Annualized Consolidated EBITDA of Supercanal Holding as at the end
of the calendar quarter then nearest ended.  For purposes hereof, the Annualized
Consolidated EBITDA of Supercanal shall be determined by reference to the
financial statements delivered to the Administrative Agent pursuant to Section

to such Section, by reference to the financial statements delivered pursuant to
the credit documents for the Syndicated Facilities or such other financial

    Agent and the Administrative Agent shall have received all information and
    copies of all documents and papers, including records of corporate
    proceedings and Governmental Approvals, if any, which the Administrative
    Agent may reasonably have requested in connection therewith, such documents
    and papers where appropriate to be certified by proper corporate or
    Governmental Authorities.

              (iii) The Administrative Agent shall have received from

insolvency, fraudulent conveyance, reorganization or other similar laws 
relating to or affecting creditors' rights generally or by general equity 
principles.  Except as reflected in the certificates delivered by the Issuers

the Acquired Issuers and to transfer or otherwise pledge the Stock of the 
Acquired Issuers.

         (c)  To the best knowledge of the Issuers, there is no reason to

Acquired Issuer or any Acquisition Subsidiary would not be granted by COMFER

such filing, the Issuers will take all additional actions and do such other 
things and execute and deliver such other documents and instruments relating 
thereto as shall be necessary or as the Collateral Agent shall reasonably 
request in order to cause such registration to be made and to cause the 
security interests granted pursuant to each such SRL Pledge Agreement to 
constitute fully perfected Liens of first and second priority, as the case 
may be, subject to no other Liens other than Liens created by the Bridge 
Purchase Documents, in each such case as soon after the Effective Date as is 
practicable.

possible, contemporaneously with the filing with the registro publico in the 
City of Buenos Aires of the application for the registration of any such 
pledge agreement (provided, no delay in the registration of such pledge

any of them in such Issuer or Acquisition Subsidiary, and (ii) prepare,

documents and instruments necessary to cause the ownership of such Stock to 
be properly registered with all appropriate Governmental Authorities, 
including, without limitation, the applicable registros publicos.  Following

Person organized as a limited liability company, without the use of 
Purchasing Agents.

sufficient to make the required prepayment.

Issuers will deliver to the Administrative Agent (i) the consolidated balance 
sheet of Supercanal Holding and its Subsidiaries as at September 30, 1997,

after the Effective Date as is practicable, but in any event within the time 
required in order for all necessary arrangements for the clearance of the 
Notes through The Depository Trust Company to be accomplished on the 
Availability Expiry Date.  For purposes hereof, the fact that Purchasers who 
are accredited investors may not hold Notes through such book-entry system 
shall not constitute an adverse effect on any right or remedy of such 
Purchaser; provided, that each such Purchaser can continue to transfer its 
Notes as provided herein.

         7.24 Interest Reserve Account.  On or before November 28, 1997, the 
Issuers will establish an interest reserve account (the "Interest Reserve

Credit Party to, create, agree to create, incur, assume or suffer to exist 
any Lien upon or with respect to any of its property or assets (real, 
personal or mixed, tangible or intangible), whether now owned or hereafter 
acquired, provided that the provisions of this Section 8.1 shall not prevent 
the creation, incurrence, assumption or existence of (all Liens described

              (i)  Liens for taxes, assessments or governmental charges or
    levies not yet due, or Liens for taxes, assessments or governmental charges

    which adequate reserves have been established in accordance with generally
    accepted accounting principles;

              (ii) Liens created pursuant to the Security Documents and the
    Bridge Purchase Documents; 

              (iii)     Liens in respect of property or assets of the any of
    the Issuers imposed by Law, which were incurred in the ordinary course of
    business and do not secure Indebtedness for borrowed money, such as
    carriers', warehousemen's, materialmen's and mechanics' liens and other
    similar Liens arising in the ordinary course of business, and which do not
    in the aggregate materially detract from the value of the 

                                      60

<PAGE>

    Issuers' respective property or assets or materially impair the use 
    thereof in the operation of the business of the Issuers;

    and the property subject thereto described, in Schedule VIII hereto and any
    other Liens in existence at the time of the consummation of the acquisition
    of the Stock or assets of any Person, to the extent such acquisition is
    permitted hereby or by the Bridge Purchase Documents;

              (v)  Liens placed upon equipment or machinery used in the
    ordinary course of business of any of the Issuers at the time of
    acquisition thereof to secure Indebtedness incurred to pay all or a portion
    of the purchase price thereof, provided that (x) the aggregate principal
    amount of all Indebtedness of the Issuers secured by Liens permitted by
    this clause (v) does not exceed U.S.$10,000,000 in the aggregate, and (y)
    in all events, the Lien encumbering the equipment or machinery so acquired
    does not encumber any other asset of the Issuers;


              (vi) pledges or deposits for the purpose of securing a stay or
    discharge in the course of any legal proceedings, provided that the
    aggregate amount of such pledges or deposits does not exceed U.S.$2,000,000
    in the aggregate; and

              (vii)     other Liens which, in the aggregate, do not encumber

    Issuers, and (y) U.S.$8,000,000.

         Notwithstanding anything contained in this Agreement to the 
contrary, none of the Issuers will create, incur, assume or suffer to exist 
any Lien (other than pursuant to the Security Documents and the Bridge 
Purchase Documents) upon any of the Stock of the Issuers (other than 
Supercanal Holding) (including any Stock of any Issuer owned by a Purchasing 
Agent), to the extent such Stock constitutes Collateral, or any other 
Collateral.

         8.2  Dividends.

         (a)  Supercanal Holding will not declare or pay any dividends, or 
return any capital, to its stockholders or authorize or make any other 
distribution, payment or delivery of property or cash to its stockholders as 
such, or redeem, retire, purchase or otherwise acquire, directly or 
indirectly, for any consideration, any shares of any class of its capital 
stock now or hereafter outstanding (or any options or warrants issued by 
Supercanal Holding with respect to its capital stock) or set aside any funds 
for any of the foregoing purposes, or permit any of its respective 
Subsidiaries to purchase or otherwise acquire for a consideration any shares 
of any class of the capital stock of Supercanal Holding now or hereafter 
outstanding (or any options or warrants issued by Supercanal Holding with 
respect to its capital stock), except as permitted or required by the 
Purchase Documents.

         (b)  Supercanal Holding will not permit any of its respective
Subsidiaries to declare or pay any dividends, or return any capital, to its

such Subsidiary with respect to its capital stock), except that any such 
Subsidiary may pay dividends to Supercanal Holding or any Subsidiary of 
Supercanal Holding for distribution to Supercanal Holding.  Nothing contained

other Credit Party to, contract, create, incur, assume or suffer to exist any

Parties outstanding at any time (less the aggregate amount of (x) any cash or 
Cash Equivalents of Supercanal Holding and/or its Subsidiaries as at such 
time in excess of U.S.$500,000, and (y) any cash or Cash Equivalents held for 
the benefit of Supercanal Holding and/or its Subsidiaries as at such time 
(other than amounts held in the Interest Reserve Account) and pledged to the

satisfactory in all respects to the Collateral Agent) exceeds the lesser of:

         (i)  the Applicable Indebtedness Amount, or

         (ii) the difference between:

              (x)  the sum of: (1) the outstanding principal amount of the
              Advances and the principal amount of Indebtedness outstanding
              under the Bridge Purchase Documents (which Indebtedness may be
              refinanced with the Indebtedness of the Proposed High Yield Debt
              Offering), (2) U.S.$10,000,000 (or its equivalent), and (3) until
              the Initial Funding Date (at which time the Indebtedness
              described in this subclause (3) shall be repaid in full), the
              aggregate amount of the Purchase Money Financing and the
              Subsidiary Indebtedness; and

              (y)  an amount equal to the amount of any mandatory prepayment
              pursuant to Sections 4.3(a) through (d) hereof;

provided, however, that no Issuer shall guaranty or otherwise become liable 
for any Indebtedness of TDH or any International Acquisition Subsidiary 
(other than any Person acquired in the Tescorp Acquisition); provided, 
further that none of Tescorp Delaware, Inversora Atelco Comodoro S.A. or 
Inversora Antena Comunitaria Trelew S.A. shall incur any Indebtedness, other 
than in each such case Indebtedness under this Agreement and the Notes and

Expenditures made the Issuers in any calendar year above is less than the 
amount set forth opposite such year, 50% of the amount of such difference may 
be carried forward and used to make Capital Expenditures in the immediately 
succeeding calendar year (after the full amount of Capital Expenditures 
otherwise permitted to be made in such year, with regard to the provision of 
this Section 8.4(c) have been made); provided, that amounts once carried 
forward to such succeeding calendar year shall lapse and terminate at the end 
of such calendar year.

         (d)  Nothing contained in this Section 8.4 shall prohibit or 
restrict Capital Expenditures made by TDH or, if acquired by the Issuers, 
Procono S.A.

    Administrative Agent of such investment and provide the Administrative 
    Agent with such information relating thereto as it may reasonably 
    request, and (y) prior to making any investment permitted by this clause 
    (i) in excess of U.S.$5,000,000 in any single or related series of 
    transactions (other than in any Approved Acquisition), the Issuers shall

    promptly request such consent of the Required Purchasers if requested to do
    so by the Issuers), (y) the aggregate of all such investments hereafter made
    by any Issuer or any Purchasing Agent shall not exceed (A) at all times

    any loans, advances or capital contributions to (x) any Excluded 
    Subsidiary (except that such investments shall be permitted to be made to 
    TDH in an aggregate amount not to exceed U.S.$2,500,000, to be used by 
    TDH to make Capital Expenditures), or (y) any International Acquisition

    lease or otherwise dispose of not more than 5% of the combined Total 
    Assets of the Credit Parties in any 12-month period; provided, however, 
    that if the proceeds of any such sale, transfer, lease or disposal are 
    retained by the Credit Parties in investments approved by the 
    Administrative Agent (such approval not to be unreasonably withheld, 
    conditioned or delayed), the Credit Parties shall be entitled to sell,

connection with the purchase of the Notes and the making of the Advances
thereunder and the taking or not taking of any action in connection herewith and
(ii) its own appraisal of the creditworthiness of the Issuers and, except as
expressly provided in this Agreement, neither the Administrative Agent nor the
Collateral Agent shall have any duty or responsibility, either initially or on a
continuing basis, to provide any Purchaser or the holder of any Note with any
credit or other information with respect thereto, whether coming into its
possession before the issue and sale of the Note or at any time or times
thereafter.  Neither the Administrative Agent nor the Collateral Agent shall be
responsible to any Purchaser or the holder of any Note for any recitals,
statements, information, representations or warranties herein or in 

                                         75

request instructions from the Required Purchasers with respect to any act or
action (including failure to act) in connection with this Agreement or any other
Purchase Document, then the Administrative Agent or Collateral Agent requesting
such instructions shall be entitled to refrain from such act or taking such
action unless and until it shall have received instructions from the Required
Purchasers.  Notwithstanding anything contained in this Agreement or the other
Purchase Documents to the contrary, no Person, including, without limitation,
any Purchaser or the holder of any Note shall have any right of action
whatsoever against the Administrative Agent or the Collateral Agent (and neither
the Administrative Agent or the Collateral Agent shall incur any liability
whatsoever) as a result of refraining from any act or taking any action as
contemplated in this Section 10.7(a).

         (b)  The Required Purchasers shall have the right to instruct the
Administrative Agent and the Collateral Agent to exercise their respective
rights and remedies granted or provided to them hereunder and under the other
Purchase Documents; provided, however that in no case shall the Administrative
Agent or the Collateral Agent be required to take any actions hereunder or under
any other Purchase Document (i) which are contrary to this Agreement, the other
Purchase Documents or applicable Law or (ii) which may, in the opinion of the
Administrative Agent or the Collateral Agent, as the case may be, result in any
liability to the Administrative Agent or the Collateral Agent, unless in the
case of this clause (ii), the Required Purchasers requesting any such action
agree to indemnify the Administrative Agent or the Collateral Agent, as the case
may be, pursuant to an instrument reasonably satisfactory to it, or post a bond
reasonably satisfactory to it.  Notwithstanding anything contained in this
Agreement or the other Purchase Documents to the contrary, no Purchaser or the
holder of any Note shall have any right of action whatsoever against the
Administrative Agent or the Collateral Agent as a result of (and neither the
Administrative Agent or the Collateral Agent shall incur any liability
whatsoever as a result of) acting or refraining from acting hereunder or under

Each of the Administrative Agent and the Collateral Agent shall be entitled to
rely, and shall be fully protected in relying, upon any note, writing,
resolution, notice, statement, certificate, telex, teletype or telecopier
message, cablegram, radiogram, order or other document or telephone message
signed, sent or made by any Person that the Administrative Agent or Collateral
Agent,

legal matters pertaining to this Agreement and any other Purchase Document and
its duties hereunder and thereunder, upon advice of counsel selected by it.

         10.9 Indemnification.  To the extent the Administrative Agent or the
Collateral Agent is not reimbursed and indemnified by the Issuers, the
Purchasers will reimburse and indemnify the Administrative Agent or the
Collateral Agent, as the case may be, in proportion to their outstanding Notes,
for and against any and all liabilities, obligations, losses, damages,
penalties, claims, actions, judgments, suits, costs, expenses or disbursements
of whatsoever kind or nature which may be imposed on, asserted against or
incurred by the Administrative Agent or the Collateral Agent, as the case may
be, in performing its duties hereunder or under any other Purchase Document, or
in any way relating to or arising out of this Agreement or any other Purchase
Document, provided that no Purchaser shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of the Administrative Agent or the Collateral Agent.

engage in any kind of banking, trust or other business with the Issuer or any
Affiliate of the Issuer as if it were not performing the duties specified

services in connection with this Agreement and otherwise without having to
account for the same to the Purchasers.

         10.11     Holders.  Each of the Administrative Agent and the
Collateral Agent may deem and treat the payee of any Note as the owner thereof
for all purposes hereof unless and until a written notice of the assignment,
transfer or endorsement thereof, as the case may be, shall have been filed with
the Administrative Agent.  Any request, authority or consent of any Person who,
at the time of making such request or giving such authority or consent, is the
holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or indorsee, as the case may be, of such Note or of any
Note or Notes issued in exchange therefor.

below or as otherwise provided below.

         (c)  Upon any such notice of resignation, the Purchasers shall appoint

successor Administrative Agent or Collateral Agent who shall serve as such
hereunder or thereunder until such time, if any, as the Purchasers appoint a
successor as provided above.

         (e)  If no successor has been appointed pursuant to clause (b) or (c)

              (iii)     The Administrative Agent shall have received from
         counsel to the Issuers (who shall be reasonably satisfactory to the
         Administrative Agent) an opinion or opinions addressed to the
         Administrative Agent, the Collateral Agent and each of the Purchasers
         and dated the date of the Funding covering such matters incident to
         the transactions contemplated hereby as the Administrative Agent may
         reasonably request.

         Section 13.    Representations and Agreements of the Purchasers.

         13.1 Securities Act.  Each Purchaser listed on Schedule I hereto as of
the Initial Funding Date hereby represents and warrants to, and agrees with, the
Issuers, as of the Initial Funding Date, as follows:

         (a)  Each Purchaser is an institutional "accredited investor" (as
defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
Act) purchasing for its own account or for the account of such an institutional
"accredited investor", each Purchaser is not acquiring the Notes with a view to,
or for offer or sale in connection with, any distribution in violation of the
Securities Act, each Purchaser has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of an
investment in the Notes, and each Purchaser and any accounts for which such
Purchaser is acting are each able to bear the economic risk of its investment.

         (b)  Each Purchaser understands that the Notes have not been
registered under the Securities Act and further agrees on its own behalf and on
behalf of any investor account for which it is purchasing the Notes to offer,
sell or otherwise transfer such Notes prior to the date which is two years after
the later of the date of original issue thereof and the last date on which any
Issuer or any affiliate of any Issuer was the owner of such Notes (the "Resale
Restriction Termination Date") only (i) pursuant to a registration statement
which has been declared effective under the Securities Act, (ii) for so long as
the Notes are eligible for resale pursuant to Rule 144A under the Securities
Act, to a person the Purchaser reasonably believes is a qualified institutional
buyer under Rule 144A (a "QIB") that purchases for its own account or for the
account of a QIB to whom notice is given that the transfer is being made in
reliance on Rule 144A, (iii) pursuant to offers and sales to non-U.S. Persons
that occur outside the United States within the meaning of Regulation S under
the Securities Act, (iv) to an institutional "accredited investor" within the
meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities
Act that is acquiring the Notes for its own account or for the account of such
an 


                                         84
<PAGE>



institutional "accredited investor" and not with a view to, or for offer or sale
in connection with, any distribution thereof in violation of the Securities Act
or (v) pursuant to any other available exemption from the registration
requirements of the Securities Act, subject in each of the foregoing cases to
any requirement of law that the disposition of its property and the property of
such investor account or accounts be at all times within its or their control
and to compliance with any applicable state securities laws.  The foregoing
restrictions on resale will not apply subsequent to the Resale Restriction
Termination Date.  If any resale or other transfer of the Notes is proposed to
be made pursuant to clause (iv) above prior to the Resale Restriction
Termination Date, the transferor shall deliver a letter from the transferee
substantially in the form of Exhibit J, which shall provide, among other things,
that the transferee is an institutional "accredited investor" within the meaning
of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act and
that it is acquiring such Notes not for distribution in violation of the
Securities Act.  The Purchasers acknowledge that the Issuers reserve the right
prior to any offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Notes pursuant to clause (v) above to require the
delivery of an opinion of counsel satisfactory to the Issuers.

         13.2 Commitment to Accept Negotiable Obligations.

         (a)  Each Purchaser agrees that if Supercanal Holding issues
Negotiable Obligations (as defined below) at any time after the date hereof, and
the Issuers request the Purchasers to accept such Negotiable Obligations as
payment for the Notes and the Advances, they will accept, as payment in full of
the Obligations, Negotiable Obligations with an aggregate principal amount not
less than the sum of outstanding principal amount of the Notes, all accrued and
unpaid interest thereon and all other amounts payable hereunder by the Issuers
hereunder and under the other Purchase Documents; provided, that (i) no Default
or Event of Default has occurred and is continuing, (ii) at the time of payment,
the issuer of the Negotiable Obligations shall not be, and shall not at any time
have been, in default under the terms and conditions of any such Negotiable
Obligations, and (iii) the Administrative Agent shall have received such legal
opinions of counsel satisfactory to the Administrative Agent and the Purchasers
covering such matters relating to the issuance, validity, enforceability of the
Negotiable Obligations, and the security therefor and such other matters as the
Administrative Agent and the Purchasers shall require.

         (b)  The term "Negotiable Obligations" shall mean bonds constituting
obligaciones negociables under Argentine Law issued by Supercanal Holding after
the date hereof in the international and Argentine capital markets, which are
(i) issued in compliance with Articles 36 and 36 bis of Argentine Law 23,576, as
amended, (ii) issued upon the same economic terms and conditions as the Notes,
and such other terms and conditions customarily included in similar
transactions, (iii) are (as to the Negotiable Obligations to be transferred to
the Purchasers) secured to the same extent as, the Notes and the other
Obligations hereunder, (iv) afford the Purchasers the same rights and remedies
provided by the Purchase Documents, and (v) otherwise in form and substance
satisfactory to the Administrative Agent and the Required Purchasers, all as
determined in the discretion of the Administrative Agent and the Required
Purchasers.

         14.4 Benefit of Agreement.  This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto, provided that none of the Issuers may assign or
transfer any of its rights or obligations hereunder without the prior written
consent of the Purchasers.

         14.5 Registration of Notes; Transfer and Exchange; Transfer
Restrictions.

         (a)  The Notes shall be issued in registered non-endorseable form
only.  Supercanal Holding shall cause to be kept at the Registrar Office and at
its offices in Argentina a register in which, subject to such reasonable
regulations as it may prescribe, Supercanal Holding shall provide for the
registration of the Notes and transfers or exchanges of the Notes as herein
provided and for the recording of the Advances and Commitments of each
Purchaser, as the same may be adjusted pursuant to an Assignment and Acceptance.
The name and address of each holder of one or more Notes, each transfer thereof
and of the Advances and Commitments in respect thereof, and the name and address
of each transferee of one or more Notes and of the Advances and Commitments in
respect thereof shall be registered in such register.  All Notes issued upon any
registration of transfer or exchange of Notes shall be the valid obligations of
the 


                                         87
<PAGE>



Company, evidencing the same obligations, and entitled to the same benefit under
this Agreement, as the Notes surrendered for such registration of transfer or
exchange.

         (b)  On or prior to the earlier to occur of (i) the Availability
Expiry Date, and (ii) the date on which the Total Commitment is funded
hereunder, any transfer of a Note shall represent a transfer of a uniform, and
not varying, percentage of the transferor's Advances made under such Note and of
such transferor's Commitment hereunder.  After the earlier to occur of (i) the
Availability Expiry Date, and (ii) the date on which the Total Commitment is
funded hereunder, any transfer of a Note shall represent a transfer of the
aggregate principal amount of the Advances thereunder.

         (c)  A Purchaser may transfer its Note and its rights and obligations
thereunder only by complying with the terms of this Agreement.  No such transfer
shall be effected until, and such transferee shall succeed to the rights of a
holder only upon, final acceptance and registration of the transfer by the
Registrar in the register.  Prior to the registration of any transfer of Notes
by a holder as provided herein, the Issuers, the Registrar and the
Administrative Agent may treat the Person in whose name the Notes are registered
as the owner thereof for all purposes and as the Person entitled to exercise the
rights represented thereby, any notice to the contrary notwithstanding.  When
Notes are presented to the Registrar with a request to register the transfer or
to exchange them, the Registrar shall register the transfer or make the exchange
in accordance with the provisions hereof.  No Purchaser shall grant a
participation under which the participant shall have rights to approve any
amendment to or waiver of any provision of this Agreement, any Note or any other
Purchase Documents except to the extent such amendment or waiver would (i)
extend the final scheduled maturity of any Advance or Note in which such
participant is participating, or reduce the rate or extend the time of payment
of interest or Fees thereon, or (ii) release all or substantially all of the
Collateral under all of the Security Documents (except as expressly provided in
such Security Documents) supporting the Advances and Notes in which such
participant is participating.

         (d)  When Notes are presented to the Registrar with a request from the
holder of such Notes to register the transfer or to exchange them, the Registrar
shall register the transfer or make the exchange as requested and provide the
transferor and the transferee with a written confirmation thereof within three
Business Days of such transfer or exchange; provided that (i) every Note
presented and surrendered for registration of transfer or exchange shall be
accompanied by an Assignment and Acceptance duly executed by the holder thereof
or the holder's attorneys duly authorized in writing pursuant to which the
holder shall have assigned a uniform, and not varying, percentage of its rights
and obligations under such Note and hereunder, (ii) the transferor and
transferee of such Notes shall have complied with their respective obligations
under Sections 14.5(g), (h), (i) and (j), and (iii) if such transfer or exchange
is made prior to the Availability Expiry Date, the Administrative Agent shall
have provided its consent.

         (e)  Upon presentment of any Note for transfer in accordance with the
provisions of Section 14.5(d) above, the Issuers shall execute and deliver, at
the Issuers' expense, one or more new Notes (as requested by the holder thereof)
in exchange therefor, in an aggregate principal amount equal to the principal
amount of the surrendered Note.  Each such new Note shall be in such principal
amount and be payable to such Person as such holder may request and shall be
substantially in the form of Exhibit A.  Each such new Note 



                                         88
<PAGE>


shall be dated and bear interest from the date to which interest shall have been
paid on the surrendered Note or dated the date of the surrendered Note if no
interest shall have been paid thereon.  Notes shall not be issued or transferred
in denominations of less than U.S.$1,000,000; provided, that if necessary to
enable the registration of transfer by a holder of  its entire holding of Notes,
one Note may be issued in a denomination of less than U.S.$1,000,000.

         (f)  If any Purchaser transfers all or a part of its Notes and its
rights and obligations hereunder to any other Person pursuant to the provisions
hereof, the transferor Purchaser shall be relieved of its obligations hereunder
with respect to the transferred Notes, Advances or Commitment, as the case may
be, and the transferee shall be a party hereto and, to the extent that Notes,
Advances and Commitments and such other rights and obligations hereunder have
been transferred, shall acquire such Notes, Advances, Commitments and other
rights and obligations of a Purchaser hereunder and under the other Purchase
Documents, and this Agreement shall be deemed to be amended to the extent
necessary to reflect the transfer and assignment of such rights and obligations
and the addition of such transferee, and any reference to the transferring
Purchaser in this Agreement, the other Purchase Documents or the Note of such
Purchaser shall thereafter refer to such Purchaser and to such transferee to the
extent of their respective interests.

         (g)  The following provisions shall apply with respect to the
registration of any proposed transfer of Notes to any institutional "accredited
investor" which is not a QIB (excluding non-U.S. Persons, as such term is
defined in Regulation S under the Securities Act): the Registrar shall register
the transfer of any Note if (i) the proposed transferee has delivered to the
Registrar and the Administrative Agent a certificate to the effect that at least
two years have elapsed since the later of (x) the original issue date of such
Notes, and (y) the last date on which any Issuer or any affiliate of any Issuer
was the owner of such Notes, or (ii) the proposed transferee has delivered to
the Registrar and the Administrative Agent a certificate substantially in the
form of Exhibit J hereto.

         (h)   The following provisions shall apply with respect to the
registration of any proposed transfer of Notes to a QIB (excluding non-U.S.
Persons, as such term is defined in Regulation S under the Securities Act): the
Registrar shall register the transfer if such transfer is being made by a
proposed transferor who has checked the box provided for on the applicable
Assignment and Acceptance stating, or has otherwise advised the Issuers, the
Registrar and the Administrative Agent in writing that the sale has been made in
compliance with the provisions of Rule 144A to a transferee who has signed a
certification stating, or has otherwise represented to the Issuers, the
Registrar and the Administrative Agent in writing, that it is purchasing the
Notes for its own account or an account with respect to which it exercises sole
investment discretion and that it and any such account is a QIB within the
meaning of Rule 144A, and is aware that the sale to it is being made in reliance
on Rule 144A and acknowledges that it has received such information regarding
the Issuers as it has requested pursuant to Rule 144A or has determined not to
request such information and that it is aware that the transferor is relying
upon its 



                                         89
<PAGE>


foregoing representations in order to claim the exemption from registration
provided by Rule 144A.

         (i)  The following provisions shall apply to the registration of any
proposed transfer of Notes to a Non-U.S. Person outside the United States (in
each case within the meaning of Regulation S under the Securities Act): the
Registrar shall register the transfer if such transfer is being made by a
proposed transferor who has checked the box provided for on the applicable
Assignment and Acceptance stating, or has otherwise advised the Issuers, the
Registrar and the Administrative Agent in writing, that the sale has been made
in compliance with Regulation S to a transferee who has signed the certification
provided for on the applicable Assignment and Acceptance, or has otherwise
advised the Issuers, the Registrar and the Administrative Agent in writing that
it is a non-U.S. Person (within the meaning of Regulation S under the Securities
Act) and that the sale has been made in compliance with the provisions of
Regulation S.

         (j)  By its acceptance of any Notes, each holder of such Notes
acknowledges the restrictions on transfer of such Notes set forth therein and in
this Agreement and agrees that it will transfer such Notes only as provided in
this Agreement.  The Registrar shall not register a transfer of any Notes unless
such transfer complies with the restrictions on transfer of such Notes set forth
in this Agreement.

         (k)  Upon receipt by the Registrar and Supercanal Holding of evidence
reasonably satisfactory to each of them of the ownership of and the loss, theft,
destruction or mutilation of any Note, and

              (x)  in the case of loss, theft or destruction, of indemnity
         reasonably satisfactory to each of them; or

              (y)  in the case of mutilation, upon surrender and cancellation
         thereof;

the Issuers, at their expense, shall execute and deliver, in lieu thereof, a new
Note, dated and bearing interest from the date to which interest shall have been
paid on such lost, stolen, destroyed or mutilated Notes or dated the date of
such lost, stolen, destroyed or mutilated Notes if no interest shall have been
paid thereon.

         (l)  The Registrar and the Administrative Agent shall retain copies of
all letters, notices and other written communications received pursuant to this
Section 14.5.  The Issuers shall have the right to inspect and make copies of
all such letters, notices or other written communications at any reasonable time
upon the giving of reasonable written notice to the Registrar and the
Administrative Agent.

         (m)  The Registrar agrees to notify Supercanal Holding from time to
time upon the registration of the transfer of any Note, Advance or Commitment
pursuant to such procedures as the Registrar and Supercanal Holding shall agree.
In the event of any conflict between any transfers or other particulars noted in
the register maintained by the Registrar and the register 


                                         90
<PAGE>


maintained by Supercanal Holding, the transfers and particulars noted in the
register maintained by the Registrar shall prevail.

         (n)  The Registrar will promptly notify the Administrative Agent upon
the registration of any transfer or exchange of Notes or any Commitments and
Advances in respect thereof.

         (o)  To permit registrations of transfers and exchanges, the Company
shall make available to the Registrar a sufficient number of duly executed Notes
to effect such registrations of transfers and exchanges.  Such Notes shall be
prepared with the date, the payee and the principal amount in blank.  The
Registrar is authorized and directed to prepare the appropriate Notes to be
delivered upon any registration of transfer or exchange and, in connection
therewith, to fill in the appropriate date, payee and principal amount, all as
contemplated hereunder and in the applicable Assignment and Acceptance.

         (p)  The Issuers hereby appoint the Registrar to act as agent of the
Issuers as set forth in this Agreement.  The Registrar hereby accepts the agency
established by this Agreement and agrees to perform the same upon the terms and
conditions herein set forth, by all of which the Issuers and the Purchasers
shall be bound.  The Registrar shall not have any obligation towards or
relationship of agency or trust for the Purchasers, except as provided in this
Section 14.5.  The Registrar shall not by any act hereunder be deemed to make
any representations as to the validity or authorization of the Notes.  The
Registrar shall not be accountable for the use or application by the Issuers of
the proceeds from the issuance of any Note.  The Registrar shall not (i) be
liable for any recital or statement of fact contained herein or for any action
taken, suffered or omitted by it in good faith in the belief that any Notes or
any other documents or any signatures are genuine or properly authorized, (ii)
be responsible for any failure on the part of the Issuers to comply with any of
their covenants and obligations contained in this Agreement or (iii) be liable
for any act or omission in connection with this Agreement except for its own
gross negligence or willful misconduct.  The Registrar is hereby authorized to
accept instructions with respect to the performance of its duties hereunder from
the President, any Vice President or the Secretary or Treasurer of Supercanal
Holding and to apply to any such officer for instructions (which instructions
will be promptly given in writing when requested) and the Registrar shall not be
liable for any action taken or suffered to be taken by it in good faith in
accordance with the instructions of any such officer; however, in its
discretion, the Registrar may in lieu thereof accept other evidence of such or
may require such further or additional evidence as it may deem reasonable.  The
Registrar shall not be liable for any action taken with respect to any matter in
the event it requests instructions from Supercanal Holding as to that matter and
does not receive such instructions within a reasonable period of time after the
request therefor.

         (q)  The Registrar may execute and exercise any of the rights and
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys, agents or employees, and the Registrar shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys, agents or employees, provided reasonable care has been exercised
in the selection and in the continued employment of any such attorney, agent or
employee.  The Registrar shall not be under any obligation or duty to institute,
appear in 



                                         91
<PAGE>



or defend any action, suit or legal proceeding in respect hereof, unless first
indemnified to its satisfaction, but this provision shall not affect the power
of the Registrar to take such action as the Registrar may consider proper,
whether with or without such indemnity.  The Registrar shall promptly notify
Supercanal Holding in writing of any claim made or action, suit or proceeding
instituted against it arising out of or in connection with this Agreement.

         (r)  The Registrar may rely and shall be fully protected in acting or
refraining from acting upon any certificate, notice, instruction, Note, document
or other writing believed by it to be genuine and to have been signed or
presented by the proper Person.  The Registrar need not investigate any fact or
matter stated in any such certificate, notice, instruction, Note, document or
other writing.  The Registrar shall not be liable for any action that it takes
or omits to take in good faith which it believes to be authorized or within its
rights or powers.

         (s)  The Issuers will perform, execute, acknowledge and deliver or
cause to be performed, executed, acknowledged and delivered all such further
acts, instruments and assurances as are consistent with this Agreement and as
may reasonably be required by the Registrar in order to enable it to carry out
or perform its duties under this Agreement.

         (t)  The Registrar shall act solely as agent of the Issuers hereunder. 
The Registrar shall not be liable except for the failure to perform such duties
as are specifically set forth herein, and no implied covenants or obligations
shall be read into this Agreement against the Registrar, whose duties and
obligations shall be determined solely by the express provisions hereof.

         (u)  The Registrar may at any time consult with legal counsel
acceptable to it (who may be legal counsel for the Issuers), and the opinion or
advice of such counsel shall be full and complete authorization and protection
to the Registrar and the Registrar shall incur no liability or responsibility to
the Issuers or to any holder for any action taken, suffered or omitted by it in
good faith in accordance with the opinion or advice of such counsel.

         (v)  The Registrar and any stockholder, director, officer or employee
of the Registrar may buy, sell or deal in any of the Notes or other securities
of the Issuers or become pecuniarily interested in transactions in which the
Issuers may be interested, or contract with or lend money to any of the Issuers
or otherwise act as fully and freely as though it were not the Registrar under
this Agreement.  Nothing herein shall preclude the Registrar from acting in any
other capacity for the Issuers or for any other legal entity.

         (w)  Except as otherwise provided in this Section 14.5, no resignation
or removal of the Registrar and no appointment of a successor registrar shall
become effective until the acceptance of appointment by the successor registrar
provided herein.  The Registrar may resign from its position as such and be
discharged from all further duties and liabilities hereunder (except liabilities
arising as a result of the Registrar's own gross negligence or willful
misconduct), after giving one month's prior written notice to the Issuers.  The
Issuers may remove the Registrar upon one month's prior written notice
specifying the date when such discharge shall take effect, and the Registrar
shall thereupon in like manner be discharged from all further duties and
liabilities hereunder, except as aforesaid.  The Registrar or the Issuers shall 


                                         92

<PAGE>

cause to be mailed (by first-class mail, postage prepaid) to each holder of a 
Note a copy of said notice of resignation or notice of removal, as the case 
may be.  Upon such resignation or removal the Issuers shall appoint in 
writing a new registrar.  If the Issuers shall fail to make such appointment 
within a period of 30 calendar days after it has been notified in writing of 
such resignation by the resigning Registrar or after such removal, then the 
resigning Registrar or the holder of any Note, at the Issuers' expense, may 
apply to any court of competent jurisdiction for the appointment of a new 
registrar.  Any new registrar, whether appointed by the Issuers or by such a 
court, shall be a bank or trust company doing business under the laws of the 
United States or any state thereof, in good standing and having a combined 
capital and surplus of not less than US$50,000,000.  The combined capital and 
surplus of any such new registrar shall be deemed to be the combined capital 
and surplus as set forth in the most recent annual report of its condition 
published by such registrar prior to its appointment, provided that such 
reports are published at least annually pursuant to law or to the 
requirements of a federal or state supervising or examining authority.  After 
acceptance in writing of such appointment by the new registrar, it shall be 
vested with the same powers, rights, duties and responsibilities as if it had 
been originally named herein as the Registrar, without any further assurance, 
conveyance, act or deed; however, the original Registrar, upon payment of its 
fees and expenses, shall in all events deliver and transfer to the successor 
Registrar all property, if any, at the time held hereunder by the original 
Registrar and if for any reason it shall be necessary or expedient to execute 
and deliver any further assurance, conveyance, act or deed, the same shall be 
done at the expense of the Issuers and shall be legally and validly executed 
and delivered by the resigning or removed Registrar.  Not later than the 
effective date of any such appointment, the Issuers shall file a notice 
thereof with the resigning or removed Registrar and shall forthwith cause a 
copy of such notice to be mailed to each holder of a Note.  Failure to give 
any notice provided for in this Section 14.5, however, or any defect therein, 
shall not affect the legality or validity of the resignation of the Registrar 
or the appointment of a new registrar, as the case may be.

         (x)  Any corporation into which the Registrar or any successor 
registrar may be merged or converted, or any corporation resulting from any 
consolidation to which the Registrar or any successor Registrar shall be a 
party, and any corporation which acquires substantially all of the corporate 
trust business of the Registrar, shall be a successor Registrar under this 
Agreement without any further act, provided that such corporation would be 
eligible for appointment as successor to the Registrar under this Section 
14.5. Any such successor Registrar shall promptly cause notice of its 
succession as Registrar to be mailed (by first-class mail, postage prepaid) 
to each holder of a Note.

         14.6 Joinder.  Upon the execution and delivery of a Joinder 
Agreement pursuant to the provisions hereof, the Person executing and 
delivering such Joinder Agreement shall be an Issuer hereunder and under the 
other Purchase Documents as provided therein.

         14.7 Payments Pro Rata.

         (a)  The Administrative Agent agrees that promptly after its receipt 
of each payment from or on behalf of the Issuers in respect of any 
Obligations of the Issuers hereunder, it 

                                     93
<PAGE>

shall distribute such payment to the Purchasers pro rata based upon their 
respective shares, if any, of the Obligations with respect to which such 
payment was received.

         (b)  Each of the Purchasers agrees that, if it should receive any 
amount hereunder (whether by voluntary payment, by realization upon security, 
by the exercise of the right of setoff or banker's lien, by counterclaim or 
cross action, by the enforcement of any right under the Purchase Documents, 
or otherwise), which is applicable to the payment of the principal of, or 
interest on, the Notes or any Advances thereunder or any Fee, of a sum which 
with respect to the related sum or sums received by other Purchasers is in a 
greater proportion than the total amount of such Obligation then owed and due 
to such Purchaser bears to the total amount of such Obligation then owed and 
due to all the Purchasers immediately prior to such receipt, then such 
Purchaser receiving such excess payment shall purchase for cash without 
recourse or warranty from the other Purchasers an interest in the Obligations 
of the Issuers to such Purchasers in such amount as shall result in a 
proportional participation by all the Purchasers in such amount; provided, 
however, that if all or any portion of such excess amount is thereafter 
recovered from such Purchaser, such purchase shall be rescinded and the 
purchase price restored to the extent of such recovery, but without interest.

         14.8 Calculations; Exclusion of Certain Persons; Computations.

         (a)  The financial statements to be furnished to the Purchasers 
pursuant hereto shall be made and prepared in accordance with U.S. or 
Argentine GAAP, as applicable (except as set forth in the notes thereto or as 
otherwise disclosed in writing by the Issuers to the Purchasers); provided 
that such financial statements shall also be accompanied by convenience 
translations pursuant to which all Peso amounts will be converted into 
Dollars both (i) using the Noon Buying Rate as in effect on the last day of 
the respective fiscal quarter or year of the Borrower, as the case may be, 
and (ii) on the basis provided in Section 14.8(b)(i).  All financial 
statements and other reports and certificates delivered pursuant to this 
Agreement shall be in English.

         (b)  Notwithstanding anything to the contrary contained in clause 
(a) of this Section 14.8, (i) all calculations used in determining Excess 
Cash Flow and compliance with Sections 8.7 through 8.13, inclusive, shall 
convert all Peso amounts into Dollars using the average rate of exchange 
during the relevant fiscal period based on the rates in effect in Argentina 
on each Business Day during such fiscal period, provided that in determining 
the Indebtedness-Annualized EBITDA Ratio and the Senior 
Indebtedness-Annualized EBITDA Ratio for such fiscal period the numerator 
thereof shall be calculated by converting all Peso amounts into Dollars using 
the Noon Buying Rate as in effect on the last day of the relevant fiscal 
period, (ii) for purposes of determining compliance with any incurrence tests 
set forth in Sections 8.1 through 8.6 and 8.17, any amounts so incurred or 
expended (to the extent incurred or expended in a currency other than 
Dollars) shall be converted into Dollars on the basis of the Noon Buying Rate 
as in effect on the date of such incurrence or expenditure under any 
provision of any such Section that has an aggregate Dollar limitation 
provided for therein for any fiscal period, and (iii) except as otherwise 
specifically provided herein, all computations determining compliance with 
Sections 8.7 through 8.13, inclusive, shall utilize accounting principles and 
policies in conformity with those used to prepare the historical financial 
statements heretofore delivered to the Purchasers.

                                     94

<PAGE>


         (c)  Notwithstanding anything contained in this Agreement or in any 
other Purchase Document to the contrary, no Excluded Subsidiary shall be 
subject to, or be limited or restricted by, or shall be considered a 
Subsidiary of any Issuer for the purposes of, or be included in any 
calculations of the ratios in, the determination of Excess Cash Flow or the 
covenants contained in Sections 8.7 through 8.13, including for purposes of 
calculating the assets, liabilities or Subscribers of any Issuer.  For 
purposes hereof, the term "Excluded Subsidiary" shall mean (i) TDH, (ii) 
Procono S.A., and (iii) Supercanal Bolivia and Integra Cable S.A.; provided, 
if the assets, liabilities and results of operations of Supercanal Bolivia or 
Integra Cable S.A. are included in the consolidated financial statements of 
Supercanal Holding provided to the Administrative Agent pursuant to Section 
7.1, such company shall not be an Excluded Subsidiary during the period 
covered by such financial statements.

         (d)  All computations of interest and Fees hereunder shall be made 
on the basis of a year of 360 days for the actual number of days (including 
the first day but excluding the last day) occurring in the period for which 
such interest or Fees are payable.

         14.9 Governing Law; Submission to Jurisdiction; Venue.

         (a)  This Agreement and the other Purchase Documents and the rights 
and obligations of the parties hereunder and thereunder shall be construed in 
accordance with and be governed by the law of the State of New York, except 
as is otherwise specifically provided in such Purchase Document.  Any legal 
action or proceeding with respect to this Agreement or any other Purchase 
Document may be brought in the courts of the State of New York sitting in the 
City and the County of New York or of the United States for the Southern 
District of New York, and, by execution and delivery of this Agreement, each 
of the Issuers hereby irrevocably accepts for itself and in respect of its 
property, generally and unconditionally, the non-exclusive jurisdiction of 
the aforesaid courts. Each of the Issuers hereby irrevocably designates, 
appoints and empowers the Process Agent, as its designee, appointee and agent 
to receive, accept and acknowledge for and on its behalf, and in respect of 
its property, service of any and all legal process, summons, notices and 
documents which may be served in any action or proceeding.  If for any reason 
such designee, appointee and agent shall cease to be available to act as 
such, each of the Issuers agrees to designate a new designee, appointee and 
agent in New York City on the terms and for the purposes of this provision 
satisfactory to the Administrative Agent. Each of the Issuers further 
irrevocably consents to the service of process out of any of the 
aforementioned courts in any such action or proceeding by the mailing of 
copies thereof by registered or certified mail, postage prepaid, to the 
Issuers at the address set forth opposite its signature below, such service 
to become effective 30 days after such mailing.  Nothing herein shall affect 
the right of the Administrative Agent, the Collateral Agent, any Purchaser or 
the holder of any Note to serve process in any other manner permitted by law 
or to commence legal proceedings or otherwise proceed against the Issuers in 
any other jurisdiction.

         (b)  To the extent permitted by Law, each of the Issuers hereby
irrevocably waives any objection which it may now or hereafter have to the
laying of venue of any of the aforesaid actions or proceedings arising out of or
in connection with this Agreement or any other Purchase Document brought in the
courts referred to in clause (a) above and hereby further 

                                     95

<PAGE>

irrevocably waives and agrees not to plead or claim in any such court that 
any such action or proceeding brought in any such court has been brought in 
an inconvenient forum.

         (c)  Each of the Issuers agrees, to the extent permitted by 
applicable law, that in any legal action or proceeding arising out of or in 
connection with this Agreement or any other Purchase Document (the 
"Proceedings") anywhere (whether for an injunction, specific performance, 
damages or otherwise), no immunity (to the extent that it may at any time 
exist) from those Proceedings, from attachment (whether in aid of execution, 
before judgment or otherwise), or from judgment shall be claimed by it or on 
its behalf or with respect to its assets.  Each of the Issuers agrees, to the 
extent permitted by applicable law, that it is and its assets are, and shall 
be, subject to such Proceedings, attachment or execution in respect of its 
obligations under this Agreement and each other Purchase Document to which it 
is party.

         14.10     Obligation to Make Payments in Dollars.  The obligation of 
the Issuers to make payment in Dollars of the principal of and interest on 
the Notes and any other amounts due hereunder or under any other Purchase 
Document to the Payment Office of the Administrative Agent as provided in 
Section 4.4 shall not be discharged or satisfied by any tender, or any 
recovery pursuant to any judgment, which is expressed in or converted into 
any currency other than Dollars, except to the extent such tender or recovery 
shall result in the actual receipt by the Administrative Agent at its Payment 
Office on behalf of the Purchasers or holders of the Notes of the full amount 
of Dollars expressed to be payable in respect of the principal of and 
interest on the Notes and all other amounts due hereunder or under any other 
Purchase Document.  The obligation of the Issuers to make payments in Dollars 
as aforesaid shall be enforceable as an alternative or additional cause of 
action for the purpose of recovery in Dollars of the amount, if any, by which 
such actual receipt shall fall short of the full amount of Dollars expressed 
to be payable in respect of the principal of and interest on the Notes and 
any other amounts due under any other Purchase Document, and shall not be 
affected by judgment being obtained for any other sums due under this 
Agreement or under any other Purchase Document.  The Issuers assume and will 
be liable in respect of any future circumstance (including acts of God or 
force majeure) which may affect the exchange market or mechanism available 
for the purchase of Dollars in such a way as to hinder or make more onerous 
obtaining the Dollars owed hereunder and under the Notes and agree to provide 
the Administrative Agent with Dollar Denominated Securities as contemplated 
herein or take any other similar or other actions permitted by applicable law 
to enable the Issuers to make full payment, in Dollars, of the Obligations in 
accordance with the provisions of this Agreement and the Notes. The Issuers 
waive the right to invoke any defense of payment impossibility (including any 
defense under Section 1198 of the Argentine Civil Code).

         14.11     Counterparts.  This Agreement may be executed in any 
number of counterparts and by the different parties hereto on separate 
counterparts, each of which when so executed and delivered shall be an 
original, but all of which shall together constitute one and the same 
instrument.

                                     96

         14.12     Effectiveness.  This Agreement shall become effective on 
the date (the "Effective Date") on which the parties hereto shall have duly 
executed and delivered a copy hereof (whether the same or different copies).

         14.13     Headings Descriptive.  The headings of the several 
sections and subsections of this Agreement are inserted for convenience only 
and shall not in any way affect the meaning or construction of any provision 
of this Agreement.

         14.14     Amendment or Waiver.  Neither this Agreement nor any other 
Purchase Document nor any terms hereof or thereof may be changed, waived, 
discharged or terminated unless such change, waiver, discharge or termination 
is in writing signed by the Required Purchasers and the Administrative Agent; 
provided, however, that no such change, waiver, discharge or termination 
shall, without the consent of each Purchaser, (i) extend the final maturity 
of any Advance or Note, or reduce the rate or extend the time of payment of 
interest or Fees thereon, or reduce the principal amount thereof, or increase 
the Commitment of any Purchaser over the amount thereof then in effect (it 
being understood that a waiver of any Default or Event of Default or of a 
mandatory reduction in the Total Commitment shall not constitute a change in 
the terms of any Commitment of any Purchaser), (ii) release substantially all 
of the Collateral except as shall be otherwise provided in any Purchase 
Document, (iii)  amend, modify or waive any provision of this Section 14.14 
or Sections 2.1, 2.2, 2.3, 10.9, 13, 14.1, 14.2, 14.4, 14.5, 14.7, 14.8(b), 
(iv) reduce the percentage specified in the definition of Required Purchasers 
or (v) consent to the assignment or transfer by any of the Issuers of any of 
its rights and obligations under this Agreement.

         14.15     Obligations Joint and Several.  The obligations of the 
Issuers hereunder and under the Notes are joint and several.

         14.16     Authorization.  Each Issuer hereby authorizes, and grants 
a power of attorney to, each other Issuer to execute and deliver for and on 
its behalf Notices of Funding, Notes and any other Purchase Documents which 
purport to be executed and delivered for and on behalf of such Issuer.

         14.17     Survival.  All indemnities set forth herein, including, 
without limitation, in Sections 2.6, 2.7, 4.5, 10.9 and 14.1, shall survive 
the execution and delivery of this Agreement and the Notes and the making and 
repayment of the Advances.

         14.18     Domicile of Advances.  Each Purchaser may transfer and 
thereafter carry its Advances at, to or for the account of any office, 
Subsidiary or Affiliate of such Purchaser; provided, however, that to the 
extent a transfer of Advances pursuant to this Section 14.18 would, at the 
time of such transfer, result in increased costs or taxes under Section 2.6 
or 4.5 hereof from those being charged by the respective Purchaser prior to 
such transfer, then the Issuers shall not be obligated to pay such increased 
costs or taxes (although the Issuers shall be obligated to pay any other 
increased costs or taxes of the type described above resulting from changes 
after the date of the respective transfer).

                                     97

<PAGE>


         14.19     Confidentiality.  Each of the Administrative Agent, the 
Collateral Agent, the Arranger and each Purchaser agrees to take normal and 
reasonable precautions and exercise due care to maintain the confidentiality 
of all non-public information provided to it by the Issuers pursuant to this 
Agreement or the other Purchase Documents, and no such party shall use any 
such information for any purpose or in any manner other than in connection 
with the transactions contemplated in this Agreement; except to the extent 
such information was or becomes available on a non-confidential basis from a 
source other than the Issuers; provided further, however, that any Purchaser 
may disclose such information (A) at the request or pursuant to any 
requirement of any Governmental Authority to which the Purchaser is subject 
or in connection with an examination of such Purchaser by any such authority; 
(B) pursuant to subpoena or other judicial or administrative process; (C) 
when required to do so in accordance with the provisions of any applicable 
Law; (D) to the extent reasonably required in connection with any litigation 
or proceeding to which the Purchaser or its Affiliates may be party, (E) to 
the extent reasonably required in connection with the exercise of any remedy 
hereunder or under any other Purchase Document, (F) to such Purchaser's 
independent auditors and other professional advisors, and (G) with the 
permission of Supercanal Holding. Notwithstanding the foregoing, and without 
limiting the generality of the foregoing, the Issuers authorize each 
Purchaser to disclose to any transferee (each, a "Transferee") and to any 
prospective Transferee, such financial and other information in such 
Purchaser's possession concerning the Issuers which has been delivered to the 
Administrative Agent, or the Collateral Agent or the Purchasers pursuant to 
this Agreement or in connection with the transactions contemplated hereby; 
provided that any such Transferee shall agree to be bound to keep such 
information confidential to the same extent required of the Purchasers 
hereunder.

         14.20     Base Rate Advances During Interim Period.  Notwithstanding 
anything contained in this Agreement to the contrary, the parties agree that 
during the Interim Period (as defined below) the Advances made on the Initial 
Funding Date shall bear interest at a rate per annum equal to the Base Rate 
in effect from time to time, plus 3.00%.  For purposes hereof, the term 
"Interim Period" shall mean the period commencing on the Initial Funding Date 
and ending on the earlier to occur of (i) November 30, 1997, and (ii) the 
date (the "LIBOR Commencement Date") specified in a written notice from the 
Administrative Agent to the Issuers and the Purchasers, which notice shall 
(a) be given not less than two Business Days prior to the LIBOR Commencement 
Date, (b) specify that Advances made on the Initial Funding Date shall bear 
interest from and after the LIBOR Commencement Date on the basis of LIBOR as 
provided in Section 2.5 hereof, and (c) specify LIBOR for the ensuing 
Interest Period, which Interest Period shall commence on the LIBOR 
Commencement Date and end on January 7, 1998.  All accrued interest in 
respect of the Interim Period shall be payable on the last Business Day of 
the Interim Period.

         14.21     Waiver of Security, Performance Bond, etc.  To the extent 
that any of the Issuers may be entitled to the benefit of any provision of 
Law requiring the Administrative Agent, the Collateral Agent or any Purchaser 
in any suit, action or proceeding brought in a court of Argentina or other 
jurisdiction arising out of or in connection with this Agreement, the Notes, 
any of the other Purchase Documents or any of the transactions contemplated 
hereby or thereby, to post security for litigation costs or otherwise post a 
performance bond or guaranty (cautio 

                                     98

<PAGE>

judicatum solvi or excepcion de arraigo), or to take any similar action, each 
of the Issuers hereby irrevocably waives such benefit, in each case to the 
fullest extent now or hereafter permitted under the Laws of Argentina or any 
such other jurisdiction.

         14.22     Interest Reserve Account Payments, Security Interest, etc.

         (a)  On the last Business Day of each calendar month, the Issuers 
shall pay to the Collateral Agent for deposit in the Interest Reserve Account 
an amount equal to the amount of interest that will have accrued during such 
calendar month in respect of the Advances, as set forth in a written notice 
from the Collateral Agent to Supercanal Holding dated not later than the date 
five Business Days prior to the last Business Day of such calendar month.

         (b)  On or before 12:00 noon (New York time) on each Interest 
Payment Date, the Collateral Agent shall transfer monies from the Interest 
Reserve Account to the Administrative Agent (or as the Administrative Agent 
shall designate), for the account of the Purchasers entitled thereto, to be 
applied to the payment of accrued interest.  All amounts from time to time on 
deposit in the Interest Reserve Account shall constitute collateral for the 
payment of the Advances and shall not constitute any payment of any 
Obligation until applied as provided above.  To the extent that any amounts 
so transferred from the Interest Reserve Account to the Administrative Agent 
on any Interest Payment Date are not sufficient to pay all accrued interest 
due on such date, the Issuers shall pay to the Administrative Agent on such 
date an amount equal to all remaining accrued interest due on such date.

         (c)  As security for the prompt and complete payment and performance 
when due of all of the Obligations, each of the Issuers does hereby grant, 
bargain, assign, transfer, sell, deliver and convey unto the Collateral 
Agent, its successors and assigns, and does hereby grant to the Collateral 
Agent for the benefit of the Purchasers, a continuing security interest in, 
and first Lien on, all of the Issuers' respective right, title and interest 
in, to and under the Interest Reserve Account (including any and all 
investment accounts established by the Collateral Agent to hold investments 
of funds deposited in the Interest Reserve Account), and all monies, 
securities, revenues, receipts, proceeds and other sums from time to time 
deposited or required to be deposited in the Interest Reserve Account (or any 
such investment accounts).  The security interest of the Collateral Agent 
under this Agreement extends to all interest, monies, securities and 
instruments deposited or required to be deposited in the Interest Reserve 
Account (or any such investment accounts) at any time during the continuation 
of this Agreement.

         (d)  All funds held by the Collateral Agent in the Interest Reserve 
Account shall be invested and reinvested in cash and Cash Equivalents.  All 
revenues, receipts, monies, proceeds and other sums derived in any manner 
from any amounts held in the Interest Reserve Account shall be held and 
applied in accordance with this Section 14.19.

         (e)  Upon the occurrence and during the continuance of an Event of 
Default, the Collateral Agent shall hold and apply the amounts held in the 
Interest Reserve Account, in accordance with Section 10.4 of the Credit 
Agreement.

ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE ISSUERS HEREBY KNOWINGLY, 
VOLUNTARILY AND INTENTIONALLY WAIVES THE RIGHT ANY OF THEM MAY HAVE TO A

making of the Advances, with the occurrence of each Funding in connection 
with the Tescorp Acquisition being deemed to constitute a representation and 
warranty that the representations and warranties made pursuant to this 
paragraph 4 are true and correct on the date of Funding (it being understood 
and agreed that any representation and warranty which by its terms is made as 
of a specified date shall be required to be true and correct in all material 
respects only as of such specified date):

         (a)  Each of the representations and warranties of the Issuers

         (c)  Each of the Issuers (including, Tescorp Delaware) has the power 
and authority to execute, deliver and perform the terms and provisions of 
this letter agreement and the pledge agreements and other documents and 
instruments required to be executed and delivered pursuant hereto to which it 
is party (collectively, the "Documents") and has taken all corporate or other 
action necessary to authorize the execution, delivery and performance by it 
of each such Document as has been executed and delivered as of each date this 
representation and warranty is made.  Each of the Issuers (including Tescorp 
Delaware) has duly executed and delivered each of the Documents to which it 
is party, and each such Document constitutes its legal, valid and binding 
obligation enforceable against it in accordance with its terms, except as 
such enforcement may be limited by applicable bankruptcy, insolvency, 
fraudulent conveyance, reorganization or other similar laws relating to or 
affecting creditors' rights generally or by general equity principles.

Agreement (i) will contravene any provision of any law, statute, rule or 
regulation or any order, writ, injunction or decree of any court or 
governmental instrumentality binding on any such Issuer, (ii) will conflict 
or be inconsistent with or result in any breach of any of the terms, 
covenants, conditions or provisions of, or constitute a default in respect 
of, or result in the creation or imposition of (or the obligation to create 
or impose) any Lien (other than Liens created pursuant to the Security 
Documents) upon, any of the property or assets of any Issuer or pursuant to 
the terms of any indenture, mortgage, deed of trust, credit agreement, loan 
agreement or any other material agreement, contract or instrument to which 
any Issuer is a party or by 

                                          4
<PAGE>


which any such Issuer or its properties or assets is bound or to which any 
such Issuer may be subject or (iii) will violate any provision of the 
estatutos sociales, articles of incorporation, bylaws or other organizational 
documents of any Issuer.

         (e)  Upon execution and delivery, the provisions of each of the 
pledge agreements required to be executed and delivered pursuant to paragraph 
5.c hereof will be effective to (i) create in favor of the Collateral Agent 
for the benefit of the Purchasers, a legal, valid and enforceable fully 
perfected first priority Lien on and security interest in the Stock referred 
to therein, and (ii) create in favor of the Bridge Collateral Agent for the 
benefit of the Bridge Purchasers, a legal, valid and enforceable fully 
perfected second priority Lien on and security interest in such Stock,

executed and delivered by Tescorp Delaware pursuant to paragraph 1(e) above.

         b.   The Issuers will take all steps necessary to effect the Merger

provided, however, that the Administrative Agent may provide one or more 
extensions of the time (not to exceed 60 days in each instance) by which the 
Merger shall be completed if the Administrative Agent shall have determined 
that the Issuers are diligently taking all reasonable action in order to 
effect the Merger as soon as is practicable.  The Issuers will provide to the 
Administrative Agent from time to time such information as it shall 
reasonably request in connection with the status of the Merger;

                     AMENDED STOCK PURCHASE AND MERGER AGREEMENT


         This is an Agreement dated as of November 26, 1997 between TESCORP
ACQUISITION CORPORATION ("Acquisition"), a Delaware corporation and a wholly
owned subsidiary of Supercanal Holding, S.A., ("Supercanal"), an Argentine
corporation, and TESCORP, INC. (the "Company"), a Texas corporation, which,
subject to the provisions of Paragraph 11.8(b), amends and restates a Stock
Purchase and Merger Agreement (the "Original Agreement') dated as of September
16, 1997, between Acquisition and the Company.

                                      ARTICLE I

                                    STOCK PURCHASE

         1.1     Purchase of Stock.  At the Initial Purchase Closing described
in Paragraph 1.3, Acquisition will purchase from the Company, and the Company
will sell to Acquisition, 6,006,006 shares (the "Purchased Common Stock") of
common stock, par value $.02 per share, of the Company ("Common Stock") for a
total of $20,000,000 (the "Common Stock Purchase Price").

         1.2     Deposit. (a) Simultaneously with the execution of the Original
Agreement, Acquisition delivered $5 million (the "Deposit") to the Company.  If
the Purchase Closing takes place, the Company will retain the Deposit as part of
the payment of the Common Stock Purchase Price.  If the Purchase Closing does
not take place, other than because one or more of the conditions specified in
Paragraph 8.2 is not fulfilled (other than because the condition in Paragraph
8.2(d) is not fulfilled due to an order entered by a court in a suit or
proceeding instituted by a shareholder of Supercanal or an affiliate of a
shareholder of Supercanal (a "Supercanal Shareholder Suit"), or because this
Agreement is terminated under Paragraph 9.1 or 9.2 (other than Paragraph 9.1(d),
and other than clause (ii) of Paragraph 9.1(e) due to an order entered by a
court in a Supercanal Shareholder Suit), on the Stock Purchase Closing Date
described in Paragraph 1.3, the Company will return the Deposit to Acquisition. 
If the Purchase Closing does not take place (i) because of a default by
Acquisition, (ii) because a condition specified in Paragraph 8.1 is not
fulfilled (unless that condition is also a condition specified in Paragraph 8.2
and is not due to an order of a court entered in a Supercanal Shareholder Suit)
or (iii) because this Agreement is terminated under Paragraph 9.1(d) or under
clause (ii) of Paragraph 9.1(e) due to an order entered by a court in a
Supercanal Shareholder Suit, the Deposit will be retained by the Company.

         1.3     Stock Purchase Closing. (a)  The closing of the Purchase of
the Purchased Stock, (the "Purchase Closing") will take place at the offices of
Rogers & Wells, 200 Park Avenue, New York, New York, at 10:00 a.m. New York City
time on December 5, 1997 (the "Stock Purchase Closing Date").

         (b)     At the Purchase Closing, Acquisition will deliver to the
Company the following:

<PAGE>


               (i)    Evidence of a wire transfer to an account specified by
the Company at least 24 hours before the Purchase Closing of $15,000,000.

              (ii)    A letter in which Acquisition acknowledges that it will
be acquiring the Purchased Common Stock for investment, and not with a view to
its resale or distribution.


             (iii)    A copy, executed by Supercanal, of a Programming Purchase
Agreement (the "Programming Agreement") substantially in the form of Exhibit
1.3-B(4).

         (c)     At the Purchase Closing, the Company will deliver to
Acquisition the following:

               (i)    Certificates, registered in the name of Acquisition (or,
at Acquisition's election, registered in the name of Supercanal or another
wholly owned subsidiary of Supercanal which agrees to be bound by Paragraphs 3.1
and 3.10) representing all the Purchased Common Stock.  

              (ii)    Evidence that the actions described in Paragraph 7.6 have
been taken and that the persons designated by Acquisition have been elected to
serve as directors of Acquisition from and after the Purchase Closing.

             (iii)    A copy, executed by the Company, of the Programming
Agreement.

              (iv)    A document, executed by the Company, stating that the
Deposit has been applied to pay a portion of the purchase price for the
Purchased Common Stock, and that the purchase price of the Purchased Common
Stock has been paid in full.

               (v)    A copy, executed by the Company, of a Registration
Agreement (the "Registration Agreement") substantially in the form of Exhibit
1.3-C(5).

         (d)     The certificates representing the Purchased Common Stock may
bear legends to the effect that the shares represented by those certificates
have not been registered under the Securities Act of 1933, as amended, and may
not be sold or transferred other than in transactions registered under that Act
or which are exempt from the registration requirements of that Act.

                                      ARTICLE II

                                  THE TENDER OFFERS

         2.1     The Offers. (a)  Not later than December 5, 1997, Acquisition
will make a public announcement of (i) an offer (the 

                                          2
<PAGE>


"Common Stock Tender Offer") to purchase all the outstanding Common Stock for
$4.50 per share in cash and (ii) an offer (the "Preferred Stock Tender Offer"
and, together with the Common Stock Tender Offer, the "Tender Offers") to
purchase all the outstanding Series 1995 8% Preferred Stock of Tescorp ("8%
Preferred Stock") for a per share amount in cash equal to (x) $144, plus (y) an
amount equal to accrued dividends on a share of 8% Preferred Stock from the last
date on which dividends were paid to the Expiration Date (defined below).

         (b)     The Tender Offers will not expire until at least 20 business
days, and (except as provided in subparagraph (c)) the Tender Offers will expire
not more than 60 days, after the day on which a Schedule 14D-1 relating to the
Tender Offers (the "Schedule 14D-1") is filed with the Securities and Exchange
Commission ("SEC").

         (c)     Subject to the conditions to the Tender Offers set forth on
Exhibit 2.1-C, and the other  conditions set forth in this Agreement,
Acquisition will, not later than five days after the date on which the Tender
Offers expire (the "Expiration Date") accept for payment and pay for all the
shares of Common Stock and 8% Preferred Stock which are properly tendered in
response to the Tender Officers and not withdrawn.  The obligation of
Acquisition to accept for payment and pay for shares which are properly tendered
and not withdrawn prior to the Expiration Date will not be subject to any
conditions other than those set forth on Exhibit 2.1-C.  Acquisition will not
(i) decrease the price per share of Common Stock or per share of 8% Preferred
Stock offered in the Tender Offers below that described in subparagraph (a),
(ii) decrease the number of shares being tendered for in the Tender Offers,
(iii) change the form of consideration payable in the Tender Offers, (iv) modify
or add to the conditions set forth on Exhibit 2.1-C or (v) extend the Tender
Offers to a date which is more than 60 days after the Tender Offers are
commenced, except that (w) if the Tender Offers are modified during the 60 day
period to increase the price per share payable in the Tender Offers or in any
other manner permitted by this Agreement, the Tender Offers may be extended
until 10 business days after the day on which the modification is communicated
to the Company's stockholders, (x) if anyone makes a tender offer for either the
Common Stock or the 8% Preferred Stock before the Tender Offers expire, the
Tender Offers may be extended until not more than 10 business days after the
other tender offer expires, (y) if Acquisition is prevented by an order of a
court or other governmental agency from accepting shares which are tendered, the
Tender Offers may be extended until 10 business days after Acquisition is able
to accept shares without violating any order of any court or other governmental
agency and (z) if the Minimum Condition described on Exhibit 2.1-C is not
satisfied during the 60 day period, the Tender Offers may be extended for up to
an additional 60 days to enable the Minimum Condition to be satisfied (and if,
although the Minimum Condition is not satisfied, at least 2,500,000 shares of
Common Stock and at least 35,000 shares of 8% Preferred Stock are properly
tendered and not withdrawn, Acquisition will extend the Tender Offers for at
least an additional 30 days to enable the Minimum Condition to be satisfied). 
Acquisition reserves the right to increase the price per share of Common Stock
or per share of 8% Preferred Stock offered in the Tender Offers.  If, when the
Tender Offers are scheduled to expire, the Minimum Condition has been satisfied
(assuming no subsequent withdrawals of shares 

                                          3
<PAGE>


which have been tendered), but the condition in paragraph (c) of Exhibit 2.1-C
has not been satisfied because of a non-final injunction, Acquisition will
extend the Tender Offers at least until the earliest of (A) the time all the
conditions on Exhibit 2.1-C are satisfied, (B) the time the injunction becomes
final and not appealable or (C) 90 days after the Schedule 14D-1 is filed with
the SEC.  Subject to the terms and conditions of the Tender Offers, Acquisition
will accept all shares which are validly tendered in response to the Tender
Offers and not withdrawn and will pay for those shares as soon as practicable
after the Expiration Date.

         (d)     Within five business days after the public announcement of the
Tender Offers, Acquisition will file with the SEC a Tender Offer Statement on
Schedule 14D-1 with respect to the Tender Offers (together with any amendments
or supplements, the "Schedule 14D-1") including forms of an offer to purchase, a
letter of transmittal and a summary advertisement (the Schedule 14D-1 and the
documents included in it by which the Tender Offers will be made, as they may be
supplemented or amended, being the "Offer Documents"). Each of Acquisition and
the Company agrees promptly to correct any information provided by it for use in
the Offer Documents if and to the extent that information becomes incomplete or
inaccurate in any material respect, and Acquisition will supplement or amend the
Offer Documents to the extent required by applicable securities laws, file the
amended or supplemented Offer Documents with the SEC and, if required,
disseminate the amended Offer Documents to the Company's stockholders.  The
Company and its counsel will be given a reasonable opportunity to review the
Offer Documents and all amendments and supplements to them before they are filed
with the SEC or disseminated to the Company's stockholders.


         2.2     Company Action. (a)  The Company hereby approves of and
consents to the Tender Offers and represents and warrants that its Board of
Directors (the "Board") has (i) determined that this Agreement and the
transactions contemplated by it are fair to and in the best interests of the
Company and its stockholders, (ii) approved this Agreement and the transactions
contemplated by it, including the sales of the Purchased Common Stock, the
Tender Offers and the Merger (described in Paragraph 3.1), and (iii) resolved to
recommend that the Company's stockholders accept the Tender Offers, tender their
shares in response to the Tender Offers, and approve and adopt this Agreement
and the Merger.  Simultaneously with the execution of the Original Agreement,
each of the directors and executive officers of the Company agreed to tender his
or her shares of Common Stock and 8% Preferred Stock in response to the Tender
Offers or (in the case of directors and executive officers who might as a result
of their tenders incur liability under Section 16(b) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") and who do not tender their shares)
to vote their shares in favor of the Merger.  Those agreements remain in effect
notwithstanding the changes to the Original Agreement reflected in this
Agreement.  Notwithstanding anything contained in this subparagraph (a) or
elsewhere in this Agreement, if the Board, after receiving advice from its
counsel, determines, in good faith, to withdraw, modify or amend the
recommendation, because the failure to do so could reasonably be expected to be
a breach of the directors' fiduciary duties under applicable law, that
withdrawal, modification or amendment will not constitute a breach of this
Agreement.

                                          4
<PAGE>

         (b)     The Company will file with the SEC, promptly after Acquisition
files the Schedule 14D-1, a Solicitation/Recommendation Statement on Schedule
14D-9 (together with any amendments or supplements, the "Schedule 14D-9")
containing the recommendations described in subparagraph (a) and will
disseminate the Schedule 14D-9 as required by Rule 14d-9 under the Exchange Act
promptly after the commencement of the Tender Offers and the filing by
Acquisition of the Schedule 14D-1.  The Company and Acquisition each agrees to
correct promptly any information provided by it for use in the Schedule 14D-9 if
and to the extent that information becomes incomplete or inaccurate in any
material respect and the Company will file any corrected Schedule 14D-9 with the
SEC and disseminate the corrected Schedule 14D-1 to the Company's stockholders
to the extent required by applicable federal securities laws.

         (c)     In connection with the Tender Offers, the Company will
promptly furnish Acquisition with mailing labels, security position listings and
any other available listing or computer files containing the names and addresses
of the record holders or beneficial owners  of shares of Common Stock or 8%
Preferred Stock (together, "Shares") as of a recent date and the Company will
furnish Acquisition with such additional information and assistance (including,
without limitation, updated lists of stockholders, mailing labels and lists of
securities positions) as Acquisition or its agents may reasonably request in
order to communicate the Tender Offers to the record holders and beneficial
owners of the Common Stock and the 8% Preferred Stock.  Subject to the
requirements of applicable law, Acquisition will hold in confidence the
information contained in any such labels, listings or files, and will use that
information only in connection with the Tender Offers and the Merger.  If this
Agreement is terminated, Acquisition will return to the Company the originals
and all copies of that information in Acquisition's possession.


                                     ARTICLE III

                                      THE MERGER


         3.1     Agreement to Effect Merger.  If (a) Acquisition purchases
pursuant to the Tender Offers at least the minimum number of shares of Common
Stock and 8% Preferred Stock (the "Minimum Shares") required to satisfy the
Minimum Condition described on Exhibit 2.1-C (the "Minimum Condition") and (b)
the conditions to the Merger set forth in paragraphs 8.1 and 8.2 are satisfied
or waived, Acquisition will take all steps in its power, including voting all
Shares beneficially owned by it at a meeting of the Company's stockholders in
favor of approval of this Agreement, to cause Acquisition to be merged into the
Company (the "Merger") on the terms and with the effects set forth in Paragraphs
3.2 through 3.8.

         3.2     The Merger.  If Acquisition purchases at least the Minimum
Shares pursuant to the Tender Offers and the conditions of the Merger set forth
in paragraphs 8.1 and 8.2 are satisfied or waived, at the Effective Time
described in Article IV, Acquisition will be merged into the Company, which will
be the surviving corporation of the Merger (the "Surviving Corporation"). 
Except as specifically provided in this Agreement, the real and personal
property, other assets, rights, privileges, immunities, powers, purposes and
franchises of the Company will continue unaffected and 

                                          5
<PAGE>


unimpaired by the Merger.  When the Merger becomes effective, the separate
existence of Acquisition will terminate, Acquisition's real and personal
property, other assets, rights, privileges, immunities, powers, purposes and
franchises will be merged into the Surviving Corporation, and the Merger will
have the other effects specified in Section 259 of the Delaware General
Corporation Law (the "DGCL") and Article 5.06 of the Texas Business Corporation
Act (the "TBCA").

         3.3     Certificate of Incorporation.  From the Effective Time until
subsequently amended, the Articles of Incorporation of the Surviving Corporation
will be in the form of Exhibit 3.3, and those Articles of Incorporation,
separate and apart from this Agreement, may be certified as the Articles of
Incorporation of the Surviving Corporation.

         3.4     By-Laws.  At the Effective Time, the By-Laws of the Surviving
Corporation will be in the form of Exhibit 3.4, until they are altered, amended
or repealed.

         3.5     Directors.  The persons listed on Exhibit 3.5 will be the
directors of the Surviving Corporation after the Effective Time and will hold
office in accordance with the By-Laws of the Surviving Corporation for the
respective terms shown on Exhibit 3.5.

         3.6     Officers.  The persons listed on Exhibit 3.6 will be the
officers of the Surviving Corporation after the Effective Time and will hold
office at the pleasure of the Board of Directors of the Surviving Corporation.  

         3.7     Stock of the Company. (a) Except as provided in subparagraph
(c), at the Effective Time each share of Common Stock which is outstanding
immediately before the Effective Time will be converted into and become the
right to receive $4.50 in cash, or any higher price per share paid with regard
to shares of Common Stock tendered in response to the Common Stock Tender Offer
(the "Common Stock Merger Price").

         (b)     Except as provided in subparagraph (c), at the Effective Time
each share of 8% Preferred Stock which is outstanding immediately before the
Effective Time will be converted into and become the right to receive in cash
the per share amount paid with regard to shares of 8% Preferred Stock tendered
in response to the Preferred Stock Tender Offer (except that if a dividend is
paid with regard to the 8% Preferred Stock between the Expiration Date and the
Effective Time, each share of Preferred Stock will be converted into and become
the right to receive $144 in cash without regard to any accrued but unpaid
dividends).

         (c)     Each share of Common Stock or 8% Preferred Stock held in the
treasury of the Company, and each share of Common Stock or 8% Preferred Stock
held by Acquisition or by any direct or indirect subsidiary of the Company,
immediately before the Effective Time will, at the Effective Time, be cancelled
and cease to exist and no payment will be made with respect to any such shares.

         3.8     Stock of Acquisition.  At the Effective Time, each share of
common stock, par value $.01 per share, of Acquisition ("Acquisition common
stock") which is outstanding immediately before the Effective Time will be
converted into and become one share of common stock 

                                          6
<PAGE>


of the Surviving Corporation ("Surviving Corporation Common Stock").  At the
Effective Time, a certificate which represented Acquisition common stock will
automatically become and be a certificate representing the number of shares of
Surviving Corporation Common Stock into which the Acquisition common stock
represented by the certificate was converted.

         3.9     Stockholders Meeting. If Acquisition purchases the Minimum
Shares pursuant to the Tender Offers and if approval by the Company's
stockholders is required by applicable law in order to consummate the Merger,
the Company will:

         (a)     hold a special meeting of its stockholders as soon as
practicable following the Expiration Date for the purpose of adopting this
Agreement and approving the Merger (the "Stockholders Meeting");  

         (b)     as promptly as practicable after the Expiration Date, (i) file
with the SEC a proxy statement (the "Proxy Statement") and other proxy
soliciting materials relating to the Stockholders Meeting, (ii) respond promptly
to any comments made by the SEC with respect to the Proxy Statement or other
proxy soliciting materials, (iii) cause the Proxy Statement to be mailed to its
stockholders at the earliest practicable time following the Expiration Date, and
(iv) in all other respects, use its best efforts to cause its stockholders to
adopt this Agreement and approve the Merger;  

         (c)     include in the Proxy Statement relating to the Stockholders
Meeting the recommendation of the Board that the stockholders of the Company
vote in favor of the adoption of this Agreement, unless the Board, after
receiving advice from its counsel, determines in good faith, that the failure to
amend or withdraw such recommendation could reasonably be expected to be a
breach of the directors' fiduciary duties under applicable law.

         3.10    Voting by Acquisition.   If Acquisition Purchases at least the
Minimum Shares pursuant to the Tender Offers, or waives the Minimum Condition
and purchases the shares which are properly tendered in response to the Tender
Offers and not withdrawn, (a) Acquisition will not dispose of any of stock of
the Company until the earlier of the Effective Time or such time as this
Agreement is terminated (except to Supercanal or a subsidiary of Supercanal
which agrees to be bound by Paragraph 3.1 and this Paragraph) and (b)
Acquisition will vote all shares of Common Stock and 8% Preferred Stock which
Acquisition owns or otherwise has the power to vote in favor of the adoption of
this Agreement and approval of the Merger. 

         3.11    Dissenting Shares.(a)  Notwithstanding any provision of this
Agreement to the contrary, Shares that are outstanding immediately prior to the
Effective Time which are held by stockholders who have complied with Article
5.12 of the TBCA (including filing a written objection to approval of the
Merger, not having voted in favor of the Merger or consented to it in writing
and having properly demanded payment of the fair value of those shares) will not
be converted into the right to receive the consideration described in Paragraph
3.2.  Instead, if the Merger takes place, 

                                          7
<PAGE>


the Surviving Corporation will pay the holders of those shares the fair value of
the shares determined as provided in Article 5.12 of the TBCA.  Shares held by
stockholders who fail to perfect, or who otherwise withdraw or lose their rights
to receive the fair value of their shares determined under Article 5.12 of the
TBCA will, at the later of the Effective Time or the time they fail to perfect,
withdraw or lose, their rights to receive the fair value of their shares, be
deemed to have been converted into the right to receive the per share sum
described in Paragraph 3.7 (the "Merger Price") without any interest.

         (b)     The Company will promptly give Acquisition (i) notice of any
demands for appraisal received by the Company, any withdrawals of any such
demands, and any other instruments served pursuant to Article 5.12 of the TBCA
which are received by the Company and (ii) the opportunity to direct all
negotiations and proceedings with respect to demands for appraisal under the
TBCA.  The Company will not, except with the prior written consent of
Acquisition, make any payment with respect to any demands for payment of the
fair value of shares or offer to settle or settle any such demand.

         3.12    Payment for Shares. (a)  Prior to the Effective Time,
Acquisition will designate a bank or trust company to act as Paying Agent in
connection with the Merger (the "Paying Agent").  At, or immediately prior to,
the Effective Time, Acquisition will provide the Paying Agent with the funds
necessary to make the payments contemplated by Paragraph 3.7.  Until used for
that purpose, the funds will be invested by the Paying Agent, as directed by
Acquisition, in obligations of or guaranteed by the United States of America or
of any agency thereof and backed by the full faith and credit of the United
States of America, in commercial paper obligations rated A-1 or P-1 or better by
Moody's Investors Services Inc. or Standard & Poors' Corporation, respectively,
or in deposit accounts, certificates of deposit or banker's acceptances of,
repurchase or reverse repurchase agreements with, or Eurodollar time deposits
purchased from, commercial banks with capital, surplus and undivided profits
aggregating in excess of $200 million (based on the most recent financial
statements of such bank which are then publicly available at the SEC or
otherwise).

         (b)     Promptly after the Effective Time, the Surviving Corporation
will cause the Paying Agent to mail to each person who was a record holder of
Common Stock or 8% Preferred Stock at the Effective Time, a form of letter of
transmittal for use in effecting the surrender of stock certificates
representing Common Stock or 8% Preferred Stock ("Certificates") in order to
receive payment of the Merger Price.  Upon surrender to the Paying Agent of a
Certificate, together with a properly completed and executed letter of
transmittal and any other required documents, the Paying Agent will pay to the
holder of the Certificate the Merger Price with regard to the shares represented
by the Certificate, and the Certificate will be cancelled.  No interest will be
paid or accrued on the cash payable upon the surrender of Certificates.  If
payment is to be made to a person other than the person in whose name a
surrendered Certificate is registered, the surrendered Certificate must be
properly endorsed or otherwise be in proper form for transfer, and the person
who surrenders the Certificate must provide funds for payment of any transfer or
other taxes required by reason of the 

                                          8
<PAGE>


payment to a person other than the registered holder of the surrendered
Certificate or establish to the satisfaction of the Surviving Corporation that
the tax has been paid.  After the Effective Time, a Certificate which has not
been surrendered will represent only the right to receive the Merger Price,
without any interest.

         (c)     At any time which is more than six months after the Effective
Time, the Surviving Corporation may require the Paying Agent to deliver to it
any funds which had been made available to the Paying Agent and have not been
disbursed to holders of Shares (including, without limitation, interest and
other income received by the Paying Agent in respect of the funds made available
to it), and after the funds have been delivered to the Surviving Corporation,
former stockholders of the Company must look to the Surviving Corporation for
the consideration to which they are entitled under Paragraph 3.7 upon surrender
of the Certificates held by them.  Neither the Surviving Corporation nor the
Paying Agent will be liable to any former stockholder of the Company for any
Merger consideration which is delivered to a public official pursuant to any
abandoned property, escheat or similar law. 

         (d)     After the Effective Time, no transfers of shares of Common
Stock or 8% Preferred Stock will be recorded on the stock transfer books of the
Company or the Surviving Corporation, and the stock ledger of the Company will
be closed.  If, after the Effective Time, Certificates are presented for
transfer, they will be cancelled and treated as having been surrendered for the
Merger consideration. 

         3.13    Options and Warrants.  To the extent that the Company has not
fulfilled prior to the Effective Time all the Company's obligations under all
options and warrants which are outstanding at the date of this Agreement, taking
account of changes in the options and warrants described in Paragraph 7.7(a),
the Surviving Corporation will fulfill those obligations.  To the extent the
Surviving Corporation is required to pay cash due to exercise of an option or
warrant after the Effective Time, instead of requiring the exercising holder to
pay the exercise price, upon receiving a notice of exercise, the Surviving
Corporation will pay the holder the amount due on exercise minus the exercise
price.

Merger") substantially in the form of Exhibits 4.2(1) and 4.2(2) and deliver
them to Rogers & Wells for filing with the Secretaries of State of Texas and

Merger Date that all the conditions in Article VIII have been fulfilled or
waived, it is to cause the applicable Certificate of Merger to be filed with the
Secretary of State of Texas and to cause the applicable Certificate of Merger to

                                      ARTICLE V

                    REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Acquisition and to Supercanal
(to induce Supercanal to execute the Guaranty attached to this Agreement) that,
except as set forth in the written disclosure schedule delivered by the Company
to Acquisition (the "Company Disclosure Schedule"):

         5.1     Organization and Qualification; Subsidiaries.  Each of the
Company and each of its subsidiaries is a corporation, partnership, sociedad
anonima, limited liability company or sociedad de responsabilidad limitada duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite power and authority and
is in possession of, and in compliance with, all franchises, grants,
authorizations, licenses, permits, easements, variances, consents, certificates,
approvals, exemptions and orders ("Approvals") necessary to enable it to own,
lease and operate the properties it purports to own, lease or operate and to
carry on its business as it is now being conducted and as proposed to be
conducted, except where the failure to have such Approvals could not reasonably
be expected to have a Material Adverse Effect on the Company.  Each of the
Company and each of its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of the properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that could not
reasonably be expected to have a Material Adverse Effect on the Company.  A true
and complete list of all of the Company's subsidiaries, together with the
jurisdiction of incorporation of each subsidiary and the percentage of each
subsidiary's outstanding capital stock owned by the Company or another
subsidiary is set forth in the Company Disclosure Schedule.  Except as set forth
in the Company Disclosure Schedule and except for interests in subsidiaries of
the Company, neither the Company nor any of its subsidiaries owns, directly or
indirectly, any interest or investment (whether equity or debt) in any
corporation, partnership, 

                                          10

limited liability company, joint venture, business, trust or entity.  For the
purposes of this Agreement, a "Material Adverse Effect" upon a company is a
material adverse change in the financial condition, operating results, business
or prospects of that company and its subsidiaries taken together.

         5.2     Certificate of Incorporation and By-Laws.  The Company has
heretofore furnished to Acquisition or Supercanal a complete and correct copy of
its Articles of Incorporation and By-Laws, and has furnished or made available
to Acquisition or Supercanal the Articles of Incorporation and By-Laws (or
equivalent organizational documents) of each of its subsidiaries (the
"Subsidiary Documents").  Those Articles of Incorporation, By-Laws and
Subsidiary Documents are listed on the Company Disclosure Schedule, are in full
force and effect and have not been amended.  Except as disclosed in the Company
Disclosure Schedule, neither the Company nor any of its subsidiaries is in

or Subsidiary Documents.

Schedule sets forth each beneficial owner (as that term is defined for purposes
of the Exchange Act) of 5% or more of any class of capital stock of the Company
known to the Company and Section 5.3 of the Company Disclosure Schedule contains
a true and complete list of all affiliates of the Company (as defined in Rule
405 under the Securities Act).  Except as set forth in the Company Disclosure
Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Company or any of its subsidiaries or obligating the
Company or any of its subsidiaries to issue, sell or transfer (currently or upon
the passage of time, the payment of money or the occurrence of any other event)
any shares of capital stock of, or other equity interests in, the Company or any
of its subsidiaries.  All shares of Common Stock which the Company is or may
become obligated to issue (including, but not limited to, the Purchased Common
Stock will be, when they are issued, duly authorized, validly issued, fully paid
and nonassessable.  The Company Disclosure Schedule sets forth an accurate and
complete list of (a) each optionee under the Employee Options and the number of
shares of Common Stock issuable upon exercise of those Employee Options and (b)
each holder of record of warrants to purchase stock of the Company ("Company

Company or any of its subsidiaries to repurchase, redeem or otherwise acquire
any shares of capital stock of the Company or any of its subsidiaries or to
provide funds to or make any investment (in the form of a loan, capital
contribution or otherwise) in any subsidiary or any other entity.  Except as set
forth in the 

                                          11
<PAGE>


Company Disclosure Schedule, all of the outstanding shares of capital stock of
each of the Company's subsidiaries are duly authorized, validly issued, fully
paid and nonassessable, and all those shares are owned by the Company or another
subsidiary free and clear of all security interests, liens, claims, pledges,
agreements, limitations on the Company's voting rights, charges or other
encumbrances of any nature whatsoever.  There are no preemptive rights with
respect to any capital stock of the Company or any capital stock of any of its
subsidiaries or any agreements, arrangements or understandings to grant
preemptive rights with respect thereto.  When issued and sold as provided in
this Agreement, the Purchased Common Stock will be duly authorized, validly
issued, fully paid and nonassessable and free from any claims (including claims
to preemptive rights) of any persons.

a legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its terms, except as the enforceability thereof may

         (b)     Except as disclosed in the Company Disclosure Schedule, the

reasonably be expected to have individually or in the aggregate a Material
Adverse Effect on the Company.

circumstances pursuant to which the Company or any of its subsidiaries could
have liability to any party under Title IV of ERISA; (e) neither the Company nor

Service (the "IRS") or any other Taxing Authority, domestic or foreign,
including, without limitation, consolidated, combined and unitary tax returns;
and "Taxing Authority" means any governmental agency, board, bureau, body,

raised by any Taxing Authority or (ii) otherwise known to the Company or any of
its subsidiaries.  No issues have been raised in any examination by any Taxing
Authority with respect to the Company or any of its subsidiaries which, by
application of similar principles, reasonably could be expected to result in a
proposed deficiency for any other period not so examined.  The Company

         6.5     Ownership of Acquisition; No Prior Activities. (a)

         (b)     As of the date hereof and the Effective Time, except for

         6.6     Accuracy of Materials.  Neither the Offer Documents nor any
information supplied by Acquisition in writing for inclusion in the Schedule
14D-9 will, at the respective times the Schedule 14D-9 and the Offer Documents
are filed with the SEC and first published, sent or given to the Company's
stockholders, contain a false or misleading statement with respect to any
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.  On the date the Proxy
Statement is mailed to the Company's stockholders and on the date of the
Stockholders Meeting, none of the information supplied in writing by Acquisition
for inclusion in the Proxy Statement will be false or misleading with respect to
any material fact or will omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading or necessary to correct
any statement in any earlier communication with respect to the Stockholders
Meeting or the solicitation of proxies therefor which has become false or
misleading.  The Offer Documents will comply as to form in all material respects
with the Exchange Act and the rules and regulations under it.  Notwithstanding
the foregoing, Acquisition does not make any representation or warranty with
respect to information supplied by the Company or any of its affiliates or
representatives in writing for inclusion in the Offer Documents, the Schedule
14D-9 or the  Proxy Statement. 

         6.7     Availability of Funds.  Supercanal (i) has arranged loan
facilities which, either alone or with cash presently on hand, will provide
sufficient funds to enable Acquisition to purchase and pay for the Purchased
Common Stock (and the Option Preferred Stock, of Acquisition exercises the
Preferred Stock Purchase Option), the Shares which are tendered in response to
the Tender Offers and the Merger as contemplated by this Agreement and to
consummate the other transactions contemplated by this Agreement and (ii) will
have on the Stock Purchase Closing Date, the Expiration Date and the Effective
Date sufficient funds to enable Acquisition to fulfill the respective
obligations under this Agreement which it will be required to fulfill on each of
those dates, including but not limited to its obligations to purchase and pay
for the Purchased Common Stock, the Shares which are tendered in response to the
Tender Offers and the Merger, respectively, as contemplated by this Agreement. 
Supercanal's loan facilities permit money borrowed under the facilities to be
used to purchase and pay for Common Stock and 8% Preferred Stock purchased at
the Initial Purchase Closing, under Paragraph 1.4 or through the Tender Offers
and to carry out the Merger.  The Note Purchase Agreement dated as of November
12, 1997 among Supercanal Holding S.A. and various subsidiaries, various
financial institutions, as Purchasers, ING Baring (U.S.) Securities, Inc., as
Arranger, ING Baring (U.S.) Capital Corporation, as Administrative and
Collateral Agent, and The Bank of New York, as Registrar, as modified by a
letter agreement dated as of November 26, 1997, (the "Note Purchase Agreement"),
a copy of which was given to the Company, has not been terminated or further
modified.

         6.8     No Supercanal Shareholder Suits.  At the date of this
Agreement, no shareholder of Supercanal or affiliate of a 

                                          26
<PAGE>


shareholder of Supercanal has filed or threatened to file a suit seeking to
enjoin Supercanal or Acquisition from completing the transactions which are the
subject of this Agreement.

         6.9     Not Affiliated Shareholders.  None of Acquisition, Supercanal
or any "affiliates" or "associates" of Acquisition or Supercanal are "affiliated
shareholders" of the Company, as those terms are defined in Articles 13.01 -
13.08 of the TBCA.

                             ACTIONS PRIOR TO THE MERGER


         7.1     Activities Until Effective Time.  From the date of this
Agreement to the Effective Time, the Company will, and will cause each of its
subsidiaries to, except with the written consent of Acquisition: 

         (a)     Operate its business in the ordinary course and in a manner
consistent with the manner in which it is being operated at the date of this

Acquisition designee is notified in writing that the Company wants to make the
expenditure or expenditures and is given written materials describing in
reasonable detail the reasons the Company 

                                          27
<PAGE>

wants to make the expenditure or expenditures and, if applicable, the return the
Company expects to realize from the expenditure or expenditures, provided that
Acquisition's designee will not be permitted to object to a reduction of net
working capital which is necessary to enable the Company to pay its outstanding
obligations as they become due and payable in the ordinary course of business or
to make expenditures or payments specifically permitted in subparagraph (d) or
(g).

         (g)     Not declare or pay any dividends, or make any other

         (n)     Not issue any stock of any class, other than (i) the issuance
of Common Stock upon exercise of options or warrants which are outstanding on
the date of this Agreement and are disclosed on the Company Disclosure Schedule,

enter into any other agreements, by reason of which the Company may become

         7.2     Redemption of 10% Preferred Stock.  Not later than three
Austin, Texas business days after the Initial Stock 

                                          28
<PAGE>


Purchase Closing Date the Company will give notice of redemption of all the
outstanding shares of 10% Preferred Stock for the redemption price of $5.00 per
share plus dividends specified in the Statement of Resolution Establishing and
Designating the Series 1990 10% Convertible Preferred Stock, which was filed on
July 11, 1990.

         7.3     No Solicitation of Offers; Notice of Indications of Interest. 
(a) Except as provided in subparagraph (b), the Company will not, and will not
authorize any of its officers, directors, employees or agents to, enter into any
discussions or take any other steps, a likely result of which might be to cause
someone other than Acquisition or Supercanal to (i) solicit tenders of stock of
the Company or otherwise seek to acquire 5% or more of either the Common Stock
or the 8% Preferred Stock of the Company, other than with a view to tendering
that stock in response to the Tender Offers, (ii) acquire all or a substantial
portion of the assets of the Company and its subsidiaries (whether through
acquisitions of assets, acquisitions of stock of subsidiaries or both), or (iii)
otherwise to acquire the Company or a substantial portion of its assets if the
Minimum Shares are not validly tendered in response to the Tender Offers and not
withdrawn or if the Company's stockholders do not approve the Merger.  If the
Company learns that anyone is contemplating soliciting tenders of its stock,
acquiring 5% or more of its outstanding stock, acquiring all or a substantial
portion of its assets and those of its subsidiaries or otherwise offering to
acquire the Company or its assets if the Minimum Shares are not validly tendered
in response to the Tender Offers and not withdrawn or if its stockholders do not
approve the Merger, the Company will promptly notify Acquisition of that fact
and provide Acquisition with all information in the Company's possession
regarding the contemplated solicitation of tenders, acquisition of stock or
assets or other acquisition offer, and the Company will promptly, from time to
time, provide Acquisition with any additional information it obtains regarding
the contemplated solicitation of tenders, acquisition of stock or assets or
other acquisition offer.

                 (b)  Notwithstanding subparagraph (a), the Company may,
without breaching this Agreement, in response to an unsolicited proposal to the
Company (an "Acquisition Proposal") which the Company's Board of Directors
determines, in good faith and after consultation with the Company's independent
financial advisor, would result (if consummated pursuant to its terms) in a
transaction (an "Acquisition Transaction") which is more favorable both to the
holders of the Common Stock and to the holders of the 8% Preferred Stock than
the Tender Offers and the Merger, furnish confidential or non-public information
to the person, entity or group (a "Potential Acquiror") making that Acquisition
Proposal and enter into discussions and negotiations with that Potential
Acquiror.

         7.4     Efforts to Fulfill Conditions.    The Company will use its
best efforts to cause all the conditions set forth in Paragraph 8.1 to be
fulfilled prior to or on the Initial Stock Purchase Closing Date and Acquisition
will use its best efforts to cause all the conditions set forth in Paragraph 8.2
to be fulfilled prior to or on the Initial Stock Purchase Closing Date. 

         7.5     Indemnification and Insurance. (a)  In the event of any
threatened or actual claim, action, suit, proceeding or 

                                          29
<PAGE>

investigation, whether civil, criminal or administrative, (each an "Action")
including, without limitation, any Action in which any person who is now, or has
been at any time prior to the date of this Agreement, or who becomes prior to
the Effective Time, a director, officer, employee, fiduciary or agent of the
Company or any of its subsidiaries (the "Indemnified Parties") is, or is
threatened to be, made a party based in whole or in part on, or arising in whole
or in part out of, or pertaining to (i) the fact that he is or was a director,
officer, employee or agent of the Company or any of its subsidiaries, or is or
was serving at the request of the Company or any of its subsidiaries as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, or (ii) this Agreement or any of the
transactions contemplated by it, whether asserted or arising before or after the
Effective Time, the Company and Acquisition (prior to the Merger) and the
Surviving Corporation (after the Merger) will cooperate and use its reasonable
best efforts to defend against the Action.  The Company will indemnify and hold
harmless, and after the Effective Time the Surviving Corporation will indemnify
and hold harmless, to the fullest extent permitted by applicable law, each
Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including attorneys' fees and expenses), judgments, fines and amounts
paid in settlement in connection with any such threatened or actual claim,
action, suit, proceeding or investigation, and in the event of any such
threatened or actual Action.  Without limiting what is said in the preceding
sentence, (i) the Company, and the Surviving Corporation after the Effective
Time, will promptly pay expenses incurred by an Indemnified Party in advance of
the final disposition of any Action to the fullest extent permitted by law, (ii)
the Indemnified Parties may retain counsel satisfactory to them, and the
Company, and the Surviving Corporation after the Effective Time, will pay all
fees and expenses of one counsel for the Indemnified Parties promptly after
statements are received.  However, neither the Company nor the Surviving
Corporation will be liable for any settlement effected without its prior written
consent (which consent will not be unreasonably withheld), and the Surviving
Corporation will have no obligation to any Indemnified Party when and if a court
of competent jurisdiction determines, in a determination which becomes final and
non-appealable, that indemnification of such Indemnified Party in the manner
contemplated by this Paragraph is prohibited by applicable law.  Any Indemnified
Party wishing to claim indemnification with regard to an actual or threatened
Action under this Paragraph 7.6, upon learning of the Action or the threat of
the Action, must notify the Company and, after the Effective Time, the Surviving
Corporation, of the Action; provided that the failure to give notice will not
effect the obligations of the Company or the Surviving Corporation except to the
extent the failure to give notice materially prejudices such party.

         (b)     Acquisition agrees that all rights to indemnification existing
in favor, and all limitations on the personal liability, of the Indemnified
Parties in the Company's Certificate of Incorporation or by-laws or the charter
or by-laws or similar organizational documents of any of its subsidiaries as in
effect as of the date Agreement with respect to matters occurring prior to the
Effective Time will survive the Merger and will continue in full force and
effect for a period of not less than six after years the Effective Time;
provided, however, that all rights to indemnification in respect of any claim
asserted or made within such period shall continue until the disposition of such
claim.  The Surviving Corporation will cause the current policies 

                                          30
<PAGE>


of the directors' and officers' liability insurance to remain in effect for at
least three years after the Effective Time or will substitute policies of at
least the same coverage with terms and conditions which are not less
advantageous to the insureds than those presently maintained by the Company,
with respect to matters occurring prior to the Effective Time; provided that in
no event will the Surviving Corporation be required to expend in any one year an
amount in excess of 150% of the annual premiums currently paid by the Company
for that insurance.  If the annual premiums exceed that amount, the Surviving
Corporation will only be obligated to obtain a policy with the greatest dollar
amount of coverage available for a cost not exceeding that amount.

         (c)     This Paragraph 7.5 is intended for the benefit of the
Indemnified Parties and will be binding on all successors and assigns of
Acquisition, the Company and the Surviving Corporation.  Each of the Indemnified
Parties will be entitled to enforce this in Paragraph 7.5.

         (d)     If the Surviving Corporation or any of its successors or
assigns (i) consolidates with or merges into any other person or entity and is
not the entity which continues or survives after the consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
person or entity, then, and in each such case, provision will be made so the
successors of the Surviving Corporation assume the obligations set forth in this
Paragraph 7.5.

         7.6     Board Representation.  Not later than the Stock Purchase
Closing Date, Daniel Vila, will be elected by the Board, effective upon
completion of Acquisition's purchase of the Purchased Common Stock, to one of
the positions (of which there will not be more than seven) on the Company's
Board of Directors and the Company will use its best efforts to cause Daniel
Vila, or if he becomes unable to serve, another designee of Acquisition
reasonably acceptable to the Company, to be elected at all subsequent meetings
of the Company's stockholders at which directors are elected (except that, (i)
at any time when Acquisition and its affiliates (including Supercanal) cease to
own at least 15% of the outstanding shares of Common Stock, or (ii) if
Acquisition breaches or fails to fulfill in a material respect any of its
obligations under this Agreement within 10 days after written notice of the
failure from the Company (which states that it is a notice being given for the
purposes of this Paragraph 7.6), Acquisition will cause Daniel Vila or whoever
else may be its designee to resign.

         7.7     Options and Warrants.  (a)  The Company will use its best
efforts (including, without limitation, by amending the provisions of the
Company's Employee Stock Option Plan and its Non-Employee Director Stock Option
Plan and the option agreements which have been issued under those Plans) to
provide that, (i) immediately prior to the acceptance of Shares in response to
the Tender Offers, each holder of an outstanding option granted under either
Plan (an "Option") will become fully vested and (ii) if all the conditions on
Exhibit 2.1-C are fulfilled, (x) each Option will be cancelled and (y) the
holder of each Option will receive, not later than 10 days after the Tender
Offers expire, a cash payment from the Company equal to (I) the excess of the
Merger Price for the Common Stock over the per share exercise price of the
Option times (II) the number of shares subject to the Option when it is
cancelled.  Any such cash payments will be treated as compensation and will be
net of any applicable federal or state 

                                          31
<PAGE>


withholding tax.

         (b)     If (i) all the conditions on Exhibit 2.1-C are fulfilled, or
(ii) even though those conditions are not fulfilled, Acquisition purchases all
the Common Stock and 8% Preferred Stock which is properly tendered in response
to the Tender Offers and not withdrawn and (iii) at least 5 days after all the
10% Preferred Stock has either been converted into Common Stock or redeemed, any
holder of warrants listed in Section 5.3 of the Company Disclosure Schedule
tenders the warrants to the Company to be cancelled in exchange for payment of
(A) the excess of $4.50 per share of Common Stock over the per share exercise
price of the warrants times (B) the number of shares of Common Stock subject to
the warrants when they are cancelled, within five business days after the
warrants are tendered for cancellation, the Company will cancel the warrants and
pay the holder cash in the amount described in clauses (A) and (B).

         7.8     Use of Proceeds of Sale of Purchased Common Stock.  The
Company will use the proceeds of the sale of the Purchased Common Stock solely
(a) to pay the redemption price of the 10% Preferred Stock, (b) to repay up to
$6,780,000 of the Company's 13% Notes due February 1998, (c) to make payments to
holders of Options or warrants as contemplated by Paragraph 7.7 and (d) to make
other payments which are listed on Exhibit 7.8.  Until it uses proceeds of the
sale of the Purchased Common Stock for one or more of those purposes, the
Company will invest them in (i) securities issued by the United States Treasury
which mature not later than March 31, 1998, (ii) certificates of deposit issued
by ING Bank N.V. or an affiliate which mature no later than March 31, 1998, or
(iii) other short term debt securities to which Acquisition consents in writing
in advance.

         7.9     Purchase of KTV.  Not later than 10 days after the Stock
Purchase is competed, the Company will assign to Acquisition all the rights, if
any, the Company may have under the option to purchase the entities which
operate cable systems and in Monte Caseras and Federacion (together, the "KTV
Entities") which is described in Items 8(a) and (b) of Section 5.20 of the
Company Disclosure Schedule (the "KTV Option").  If the KTV Option has not
expired, Acquisition will exercise the KTV Option before its expiration date and
will purchase, or cause a designee to purchase, the KTV Entities on the terms
provided in the KTV Option.  If the KTV Option has expired but the owners of the
KTV Entities are willing to sell the KTV Entities to Acquisition for the
purchase price, and on the other terms, provided in the KTV Option, as promptly
as practicable after the Stock Purchase is completed, Acquisition or a designee
will purchase the KTV Entities for that purchase price and on those other terms.

         7.10    Satisfaction of Subsidiary Debt.  Not later than 15 days after
(i) the day on which Acquisition accepts the shares which are properly tendered
in response to the Tender Offers and not withdrawn, or (ii) such earlier time as
Acquisition acquires a majority of the outstanding Common Stock, the Company
will cause each of its subsidiaries listed on Exhibit 7.10 to repay in full all
its indebtedness for borrowed money and all its indebtedness incurred in
connection with acquisitions of businesses or other assets (other than trade
accounts payable incurred in the 

                                          32
<PAGE>


ordinary course of business).

         7.11    Ownership of Subsidiaries.  Not later than 20 days after the
date of this Agreement, the Company will enter into binding written agreements
with the registered owners of shares or other interests in SIR TV S.R.L., Cable
Viedma S.R.L. and Televiedma S.R.L., (together the "Tescorp S.R.L.'s") in form
reasonably satisfactory to Acquisition, in which those registered owners agree
that at any time the Company asks them to do so, they will (a) execute any
documents the Company requests that they execute in order to ensure that at the
Effective Time, the lenders under the Note Purchase Agreement will have valid
and enforceable liens on all the shares or other ownership interests in the
Tescorp S.R.L.'s, and (b) providing for the transfer of ownership of the Tescorp
S.R.L.'s to such entity or entities as Supercanal may designate.

         9.1     Right to Terminate.  This Agreement may be terminated at any
time prior to the Effective Time (whether or not 


                                          34
<PAGE>


the stockholders of the Company have approved the Merger):

         (a)     By mutual consent of the Company and Acquisition.

         (b)     By the Company if, without fault of the Company, the
Expiration Date is not on or before January 31, 1998.

         (c)     By the Company or Acquisition if, without fault of
Acquisition, the Effective Time is not on or before April 30, 1998. 

         (d)     By the Company if (i) any of the representations or warranties
of Acquisition contained in this Agreement was not complete and accurate in all
material respects on the date of this Agreement, or (ii) any of the conditions

         9.2     Manner of Terminating Agreement.  If at any time Acquisition
or the Company has the right under Paragraph 9.1 to terminate this Agreement, it
can terminate this Agreement by a notice to the other of them that it is
terminating this Agreement.

         9.3     Termination due to Superior Proposal.

         (a)     This Agreement may be terminated by the Company at any time
prior to the Stock Purchase Closing Date, if (i) it receives a Superior
Proposal, (ii) its Board of Directors resolves to accept the Superior Proposal,
(iii) the Company has given Acquisition at least ten business days' prior notice
of its intention to terminate this Agreement pursuant to this provision and (iv)
the Company has paid Acquisition $5 million (it being understood that only one
such payment will be required even if the Company is entitled to terminate this
Agreement both under this subparagraph (a) and under subparagraph (b)).  A
"Superior Proposal" is an Acquisition Proposal which would result in the
Company's stockholders receiving consideration with a fair value determined in
good faith by the Company's Board of Directors and after consultation with the
Company's independent financial advisor to be more favorable both to the holders
of the Common Stock and to the holders of the 8% Preferred Stock than the Tender
Offers and the Merger.  A notice of intention to terminate given pursuant to
this subparagraph will be irrevocable (unless Acquisition consents in writing to
its being withdrawn by the Company) and will result in this Agreement's being
terminated on the date specified in the notice of intention, which will be not
earlier than the day after the expiration of the ten business day period.  When
the Company delivers a notice of intention to terminate pursuant to this
Paragraph, Acquisition's obligations under Articles I, II, III and IV and
Paragraphs 7.2 and 7.5 will terminate.

         (b)     This Agreement may be terminated by the Company, if (A) a
tender or exchange offer is commenced by a Potential Acquiror for all the
outstanding shares of Common Stock and 8% Preferred Stock, (B) the Company's
Board of Directors determines in good faith and 

                                          35
<PAGE>


after consultation with an independent financial advisor, that the offer
constitutes a Superior Proposal and resolves to accept the Superior Proposal or
recommend to the Company's stockholders that they tender their shares in
response to the tender or exchange offer, (C) the Company has given Acquisition
at least ten business days' prior notice of its intention to terminate pursuant
to this provision, and (D) the Company has paid Acquisition $5 million (it being
understood that only one such payment will be required even if the Company is
entitled to terminate this Agreement both under this subparagraph (b) and under
subparagraph (a)).  A notice of intention to terminate given pursuant to this
subparagraph will be irrevocable (unless Acquisition consents in writing to its
being withdrawn by the Company) and will result in this Agreement's being
terminated on the date specified in the notice of intention, which will be not
earlier than day after the expiration of the ten business day period.  When the
Company delivers a notice of intention to terminate pursuant to this Paragraph,
Acquisition's obligations under Articles I, II, III and IV and Paragraphs 7.2
and 7.5 will terminate.

         9.4     Effect of Termination. (a)  If this Agreement is terminated
pursuant to Paragraph 9.1 or 9.3, after this Agreement is terminated, neither
party will have any further rights or obligations under this Agreement, other
than the parties' respective rights and obligations under Paragraphs 7.6, 11.1,
11.2, 11.3, and 11.7.  Nothing in this Paragraph will, however, (i) affect the
rights of the Company and Acquisition with respect to the Deposit as set forth
in Paragraph 1.2 or (ii) relieve either party of liability for any breach of
this Agreement which occurs before this Agreement is terminated.

         (b)     If this Agreement is terminated after the Stock Purchase
Closing Date, the termination will not affect the validity of the Stock
Purchase.  If this Agreement is terminated after Acquisition has accepted Shares
which are tendered in response to the Tender Offers, the termination will not
affect Acquisition's purchase of the Shares it has accepted or its obligation to
pay for those shares.  Either Acquisition or the Company will, however, be
entitled to seek recourse for any damages it suffers as a result of, or
otherwise in connection with, the Stock Purchases or the purchase by Acquisition
of Shares which are tendered in response to the Tender Offers because
representations and warranties in this Agreement are not accurate or because of
breaches of this Agreement which occur after those events have taken place.

commenced because Acquisition breaches its obligations under this Agreement,
Acquisition will pay those fees promptly after request by the Company.  The fees
of ING Baring (U.S. Securities, Inc.), Smith Barney, Inc. and Integra Financial
Services LLC, which together will total the lesser of (x) 2% of the total amount
paid by Acquisition for the shares it acquires through the Stock Purchase and
the Tender Offers plus the Merger Consideration or (y) $2 million, will be paid
by Acquisition.  The Company and Acquisition each indemnifies the other of them
against, and agrees to hold the other of them harmless from, all losses,
liabilities and expenses (including, but not limited to, reasonable fees and
expenses of counsel and costs of investigation) incurred because of any claim by
anyone other than the five firms named in the first sentence of this Paragraph
for compensation as a broker, a finder or in any similar capacity by reason of
services allegedly rendered to the indemnifying party in connection with the
transactions which are the subject of this Agreement.


                                      ARTICLE XI

                                       GENERAL

         11.1    Expenses.  If (i) the Tender Offers are commenced and all the
conditions on Exhibit 2.1-C are fulfilled or waived or (ii) the Tender Offers
are not commenced because Acquisition breaches its obligations under this
Agreement, Acquisition will pay (i) its own expenses and (ii) promptly after
demand by the Company, all the expenses of the Company in connection with this
Agreement and the transactions which are the subject of this Agreement,
including the fees of the firms described in Paragraph 10.1 and including legal
and accounting fees and expenses.  Otherwise, the Company and Acquisition
(together with Supercanal) each will pay its own expenses, including fees of
financial advisors and legal and accounting fees and expenses, in connection
with this Agreement and the transactions which are the subject of this
Agreement.

         11.2    Company Option to Repurchase Stock.  If the Stock Purchase
Closing takes place but Acquisition fails (i) to make the Tender Offers or (ii)
whether or not it is required to do so, to accept and pay for the Shares which
are properly tendered in response to the Tender Offers and not withdrawn, or if
this Agreement is terminated because of failure of the condition in Paragraph

exercisable by a notice to Acquisition given not later than 5:00 P.M. New York
City time on the first anniversary of the Initial Stock Purchase Closing Date,
to repurchase all (but not less than all) the Initial Purchased Common Stock, if
any, Acquisition has purchased for the price Acquisition paid for it (including
the amount of the Deposit which was applied in payment of a portion of the
purchase price of the Purchased Common Stock), payable on a date specified by
the Company in the notice of exercise of the option which is not more than 20
days after the day on which the notice of exercise is given, by a wire transfer

will surrender to the Company the certificates representing the Purchased Common
Stock.

Time, Acquisition will purchase (or will cause an affiliate to purchase) the
minority interests in cable television interests listed on Exhibit 11.3 for a

purchase specific minority interests because the current owners of those
minority interests would not sell them for the prices shown on Exhibit 11.3.

         11.4    Payment to Company.  If after the Stock Purchase Closing Date
but before the Effective Time, this Agreement is terminated (i) by the Company

III, or (ii) by Acquisition because the condition in Paragraph 8.2(d) is not
fulfilled due to a Supercanal Shareholder Suit, within 5 days after the day on
which this Agreement is terminated, Acquisition will pay the Company, by wire
transfer to the account specified in accordance with Paragraph 1.4(b)(i), the
sum of $5 million.

and its subsidiaries between the Expiration Date and the day which is three
months after the Expiration Date other than for Cause, an amount equal to the
employee's annual salary, but in no event will the Surviving Corporation be
obligated to pay those employees a total of more than $350,000 (and the amounts
payable to various employees will be reduced pro rata to the extent, if any,
necessary to reduce the total payments to $350,000).  As used in this Agreement

to perform material duties after notice of such failure has been given to the
applicable employee.

         11.6    Access to Properties, Books and Records. (a)  From the date of
this Agreement until the Merger Date or such earlier date as this Agreement is

representatives of Acquisition full access during normal business hours to all
of their respective properties, books and records.  Until the Effective Time or,
if the Merger does not take place, until the second anniversary of the date of
this Agreement, Acquisition will, and will cause its representatives to, hold
all information its representatives receive as a result of their access to the
properties, books and records of the Company or its subsidiaries in confidence,
and not use any of that information for any purpose except in connection with
the transactions which are the subject of this Agreement (including confirming

information about the Company contained in this Agreement), except to the extent
that information (i) is or becomes available to the public (other than through a

which are the subject of this Agreement or evidence that material has been
destroyed by Acquisition.

each other before issuing any press releases or otherwise making any public
statements with respect to this Agreement or the transactions contemplated by
it, except that nothing in this Paragraph will prevent either party from making
any statement when and as required by law or by the rules of any securities
exchange or securities quotation or trading system on which securities of that
party or an affiliate are listed, quoted or traded.

         11.8    Entire Agreement. (a)  This Agreement and the documents to be
delivered in accordance with this Agreement contain the entire agreement between
the Company and Acquisition relating to the transactions which are the subject
of this Agreement and those other documents, and, except as provided in
subparagraph (b), all prior negotiations, understandings and agreements between

representations, warranties, understandings or agreements concerning the
transactions which are the subject of this Agreement or those other documents
other than those expressly set forth in this Agreement or those other documents.

                 (b)  If Acquisition is obligated under this Agreement to
complete, but fails to complete, any of the Stock Purchase, the Tender Offers or
the Merger, the Company, at its option, may (i) sue for damages or seek other
recourse for breach of this Agreement, or (ii) sue for damages or seek other
recourse for breach of the Original Agreement as though this Agreement had never
been entered into, provided that in computing damages under the Original
Agreement all transactions completed under this Agreement will be taken into
account.  Under either option, the Company may seek declaratory, injunctive or
other non-monetary relief in connection with any breach of this Agreement.

                 (c)  Acquisition acknowledges that neither it nor Supercanal,
nor any of their officers, directors or agents, has any claim against the
Company or any of its officers, directors or employees, based upon a failure of
the Company to fulfill any of its obligations, or otherwise arising, under or
relating to the Original Agreement, and Acquisition waives any such claims for
itself and for Supercanal to the extent Acquisition or Supercanal may have any
such claims.

         11.9    Effect of Disclosures.  Any information disclosed by a party
in connection with any representation or warranty contained in this Agreement
(including Disclosure Statements and including exhibits to this Agreement) will

Agreement together with this Annex A.

         (i)     The number of shares properly tendered in response to the
    Tender Offers and not withdrawn, together with the shares of Common Stock
    and any shares of 8% Preferred Stock already owned by Acquisition, does not

    enacted, promulgated, entered or enforced by any national or state
    government or governmental authority or by any United States or Argentine
