                                THE CORPORATION

    Intertape develops, manufactures and sells a variety of specialised
polyolefin plastic packaging products for industrial use. These products include
pressure-sensitive and water-activated carton sealing tapes, masking and
reinforced filament pressure-sensitive tapes, duct tapes, acrylic coating,
shrink wrap, stretched wrap and woven products. Most of Intertape's products are
derived from resins that are converted into films and adhesives. Resins are also
combined with paper and converted into a variety of packaging products. Vertical
integration, whereby Intertape performs each step in the conversion of
polyolefin resins and paper into its various products, and continuous capital
expenditures to increase manufacturing efficiencies allow Intertape to be a
low-cost producer of each product it manufactures. This vertical integration
combined with the use of high-speed production equipment provides competitive
advantages to Intertape and flexibility and control of the manufacturing process
and in speed of delivery.

    Intertape's overall objective is to gain market share in large niche markets
that it believes are growing at rates faster than the economy as a whole.
Intertape's strategies for achieving this objective are as follows:
(i) solidify its position as a low-cost manufacturer; (ii) increase its
manufacturing capacity; (iii) develop new products; (iv) develop central
distribution centres; (v) evaluate future complementary acquisitions; and
(vi) expand its sales into new geographic markets.

    Intertape's registered office is located at 1155 Rene-Levesque Boulevard
West, Suite 4000, Montreal, Quebec, H3B 3V2 and its principal executive offices
are located at 110E Montee de Liesse, St-Laurent, Quebec, Canada, H4T 1N4.

                              RECENT DEVELOPMENTS

    In March 1998, Intertape announced its plans to restructure its Flexible
Intermediate Bulk Container ("FIBC") operations. Over the past several years,
the increasing levels of imported products into North America have resulted in a
continuing downward trend in the selling prices of FIBC products. This
penetration into the North American marketplace, coupled with higher domestic
manufacturing costs and worldwide currency devaluation have led to Intertape's
decision to restructure its FIBC operations. Intertape remains strongly
committed to the FIBC business and its customers and believes that the
reorganisation of its FIBC operations will allow it to improve its
competitiveness by restructuring its domestic cost base and gradually transfer
the majority of its FIBC manufacturing facilities outside Canada and the United
States.

    In May 1998, Intertape entered into a US$50 million unsecured revolving line
of credit with an American banking corporation to refinance an existing facility
of US$33 million. As of February 23, 1999, approximately US$40.8 million was
outstanding under this facility. In June 1998, Intertape completed a private
placement of US$137 million of senior guaranteed notes maturing in 2008 and
bearing interest at the rate of 6.82% per annum. The proceeds from this private
placement were used to repay debt incurred in December 1997 in connection with
the acquisition of American Tape Co. and to repay short-term credit facilities.

    In September 1998, Intertape completed the previously-announced acquisition
from Anchor Continental Holdings Inc., a wholly-owned subsidiary of Coating
Technologies International, Inc., of Anchor Continental, Inc., which
manufactures pressure-sensitive tapes including both masking and duct tapes. The
purchase price for this acquisition was approximately US$102.1 million in cash
and was entirely paid at closing. The purchase price was substantially financed
by Canadian and American banks which advanced US$100 million to Intertape. The
acquisition of Anchor Continental, Inc. is expected to enable Intertape to
expand its existing product lines, to increase its product supply to its
industrial customer base and to broaden the distribution channels for its
products.

    In October 1998, Intertape completed the previously-announced acquisition of
substantially all of the assets of the Rexford Paper Company, a division of
Inland Paperboard and Packaging, Inc. The purchase price for this acquisition
was approximately US$9.2 million in cash and was entirely paid at closing. This
acquisition will provide Intertape with complementary product lines of sensitive
tapes and water-activated tape and is expected to expand Intertape's
distribution channels.

                                USE OF PROCEEDS

    Of the estimated net proceeds of $115,670,000 to be received by Intertape
from this Offering, approximately $51.7 million (approximately US$34.5 million)
will be used to reimburse the three series of outstanding senior unsecured US
dollar notes due June 1, 2001 and issued in 1996, approximately $61.2 million
(approximately US$40.8 million) will be used to reimburse the outstanding
balance of a senior unsecured US dollar bank loan under the US$50 million
unsecured revolving line of credit and the balance for general corporate
purposes.

                                 CAPITALISATION

    The following table sets forth the consolidated capitalisation of Intertape
as of the dates indicated, before and after giving effect to the sale of the
Common Shares under this Offering, assuming the application of the estimated net
proceeds therefrom as set forth under "Use of Proceeds". This table should be

                            DETAILS OF THE OFFERING

    This Offering consists of 3,000,000 Common Shares at a price of $40.25 per
share.

    Each common share entitles the holder thereof to dividends if, as and when
declared by the directors, to one vote at all meetings of holders of common
shares and to participate, PRO RATA, with the holders of common shares, in any
distribution of the assets of Intertape upon liquidation, dissolution or
winding-up, subject to the prior rights of holders of shares ranking in priority
to common shares.

                              PLAN OF DISTRIBUTION

    Pursuant to an agreement (the "Underwriting Agreement") dated February 26,
1999 among CIBC Wood Gundy Securities Inc., RBC Dominion Securities Inc.,
ScotiaMcLeod Inc., TD Securities Inc. and Trilon Securities Corporation
(collectively, the "Underwriters") and Intertape, Intertape has agreed to sell
and the Underwriters have agreed to purchase on March 16, 1999 or on such other
date as may be agreed upon, but in any event not later than April 30, 1999 (the
"Closing Date"), subject to the terms and conditions contained therein, and the
approval of certain legal matters, all but not less than all of the 3,000,000
Common Shares subject to this Offering for a total consideration of $120,750,000
payable to Intertape against delivery of such Common Shares. In consideration of
their services under the Underwriting Agreement, Intertape has agreed to pay to
the Underwriters a fee in the aggregate amount of $4,830,000 ($1.61 per Common
Share).

    Pursuant to the Underwriting Agreement, the obligations of the Underwriters
are several and not joint and may be terminated upon the occurrence of certain
stated events. The Underwriters are, however, obligated to take up and pay for
all the Common Shares if any of the Common Shares are purchased under the
Underwriting Agreement.

    TD Securities Inc. is controlled by a Canadian chartered bank which is a
lender to Intertape.

    Intertape has agreed in favour of the Underwriters that it will not issue,
sell or offer, agree or become bound to issue or announce the issuance or sale,
offering or agreement to issue or sell any securities of Intertape or any
securities convertible into, exercisable for, or carrying the right to purchase
securities of Intertape, other than for purposes of (i) issuing or exercising
options under Intertape's Executive Stock Option Plan, (ii) issuing or
exercising rights under Intertape's Shareholder Protection Rights Plan or
(iii) the payment in full or in part of the purchase price of any business or
assets related to Intertape's activities, for a period of 90 days from the date
of the Closing Date, without the prior written consent of CIBC Wood Gundy
Securities Inc. on behalf of the Underwriters.

    Pursuant to policy statements of the COMMISSION DES VALEURS MOBILIERES DU
QUEBEC and the Ontario Securities Commission, the Underwriters may not,
throughout the period of distribution, bid for or purchase common shares. The
foregoing restriction is subject to exceptions, on the condition that the bid or
purchase not be engaged in for the purpose of creating actual or apparent active
trading in, or raising the price of, the common shares. Such exceptions include
a bid or purchase permitted under the by-laws and rules of the TSE relating to
market stabilisation and passive market-making activities and a bid or purchase
made for and on behalf of a customer where the order was not solicited during
the period of distribution. Subject to the foregoing, pursuant to this Offering,
the Underwriters may over-allot common shares or effect transactions

                                       5
<PAGE>
intended to stabilise or maintain the market price of the common shares at a
higher level than that which might otherwise prevail on the open market. Such
transactions may be commenced or discontinued at any time during this Offering.

    The Common Shares have not been and will not be registered under the United
States SECURITIES ACT OF 1933, as amended (the "U.S. Securities Act"), and,
accordingly, may not be offered or sold within the United States, except in
certain transactions exempt from the registration requirements of the U.S.
Securities Act. Each Underwriter has agreed that, except in accordance with the
terms of such exemptions, it will not offer, sell or deliver Common Shares
within the U.S. or any territories or possessions thereof.

    In addition, until 40 days after the commencement of this Offering, an offer
or sale of the Common Shares within the United States by any dealer (whether or
not participating in this Offering) may violate the registration requirements of
the U.S. Securities Act.

                                 LEGAL MATTERS

    Certain legal matters in respect of the Common Shares will be passed upon by
Stikeman, Elliott on behalf of Intertape and by McCarthy Tetrault on behalf of
the Underwriters. On February 25, 1999, the partners and associates of Stikeman,
Elliott and McCarthy Tetrault beneficially owned, directly or indirectly, as a
group less than 1% of the common shares.

                           ELIGIBILITY FOR INVESTMENT

Tetrault, counsel to the Underwriters, based on legislation in effect at the

income fund or a deferred profit sharing plan.
