Dear Stockholder:
 
     You are cordially invited to attend a Special Meeting of Stockholders (the
"Special Meeting") of PureTec Corporation (the "Company") to be held at 10:00
a.m., local time, on February 25, 1998 at the Saddle Brook Marriott Hotel,
located on the Garden State Parkway at the intersection with Interstate Highway
80, Saddle Brook, New Jersey 07663.
 
     As described in the accompanying Proxy Statement, at the Special Meeting
you will be asked to consider and vote on a proposal to approve and adopt an
Agreement and Plan of Merger, dated as of November 11, 1997 (the "Merger
Agreement"), among Tekni-Plex, Inc., a Delaware corporation ("Tekni-Plex"), P.T.
Holding, Inc., a Delaware corporation and a wholly owned subsidiary of
Tekni-Plex ("Sub"), Plastic Specialties and Technologies, Inc., a Delaware
corporation and an indirect subsidiary of the Company, and the Company. On the
terms and subject to the conditions of the Merger Agreement, if the stockholders
of the Company approve and adopt the Merger Agreement, Sub will be merged with
and into the Company (the "Merger"), with the Company continuing as the
surviving corporation and becoming a wholly owned subsidiary of Tekni-Plex, and
all of the presently issued and outstanding shares of common stock, $0.01 par
value, of the Company (the "Common Stock") will be converted into $3.50 per
share in cash. Detailed information concerning the Merger is set forth in the
accompanying Proxy Statement which you are urged to read carefully. A copy of
the Merger Agreement is attached as Annex I to the accompanying Proxy Statement.
 
     Approval and adoption of the Merger Agreement requires the affirmative vote
of a majority of the outstanding shares of Common Stock held by stockholders of
record on January 6, 1998 (the "Record Date"). Pursuant to a Stockholder Voting
and Option Agreement, dated as of November 11, 1997, between Tekni-Plex and
certain directors and executive officers of the Company who beneficially own
approximately 9% of the outstanding shares of Common Stock entitled to vote at
the Special Meeting (the "Stockholder Voting Agreement"), such directors and
executive officers, in their capacity as stockholders of the Company, have
agreed, among other things, to vote their shares in favor of the Merger and the
adoption of the Merger Agreement. A copy of the Stockholder Voting Agreement is
attached as Annex II to the accompanying Proxy Statement.
 
     Holders of Common Stock will be entitled to dissenters' rights under
Delaware law in connection with the Merger as described in the accompanying
Proxy Statement.
 
     Your Board of Directors has carefully reviewed and considered the terms and
conditions of the Merger Agreement and has determined that the Merger Agreement
and the Merger are fair to and in the best interests of the Company and its
stockholders AND HAS UNANIMOUSLY APPROVED AND ADOPTED THE MERGER AGREEMENT AND
RECOMMENDS THAT YOU VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY. In reaching its determination, your Board
of Directors considered, among other things, the opinion of Schroder & Co. Inc.
("Schroders"), that as of the date of such opinion and based upon and subject to
certain matters stated therein, the consideration to be received by the holders
of Common Stock in the Merger other than Tekni-Plex, Sub and their affiliates,
was fair from a financial point of view. The opinion of Schroders is included as
Annex III to the accompanying Proxy Statement. You are urged to read the opinion
in its entirety for further information with respect to the assumptions made,
matters considered and limits of the review undertaken by Schroders.
 
     I urge you to read the enclosed material carefully and request that you
promptly complete and return the enclosed proxy in the enclosed return envelope,
which requires no postage if mailed in the United States. If you attend the
Special Meeting, you may vote in person even if you have previously returned
your proxy. YOUR VOTE IS IMPORTANT REGARDLESS OF THE NUMBER OF SHARES YOU OWN.
THE MERGER CANNOT BE COMPLETED UNLESS THE STOCKHOLDERS OF THE COMPANY APPROVE
AND ADOPT THE MERGER AGREEMENT.
 
                                       Sincerely,

encourage companies to provide prospective information about their businesses.
Forward-looking statements include statements concerning plans, objectives,
goals, strategies, future events or performance, and underlying assumptions and
other statements that are not statements of historical facts. Forward-looking
statements contained or incorporated by reference in this Proxy Statement were
not prepared in compliance with the published guidelines of the American
Institute of Certified Public Accountants or the Commission regarding
projections or financial forecasts.
 
     The forward-looking statements set forth or incorporated by reference in
this Proxy Statement are based upon various assumptions, many of which are
based, in turn, upon further assumptions, including without limitation,
management's examination of historical operating trends, data contained in the
Company's records and other data available from third parties. Although the
Company believes that such assumptions are reasonable, because such assumptions
are inherently subject to significant uncertainties and contingencies that are
difficult or impossible to predict and are beyond the Company's control, there
can be no assurance, and no representation or warranty is made, that
management's expectations, beliefs or projections will result or be achieved or
accomplished. In addition to the other factors and matters discussed elsewhere
herein and in the documents incorporated by reference herein, factors that, in
the view of the Company, could cause actual results to differ materially from
those discussed in the forward-looking statements include: (i) economic
slowdowns in any one, or all, of the Company's market segments; (ii) unforeseen
price pressure on the Company's products or significant cost increases that
cannot be recovered through price increases or

productivity improvements; (iii) significant changes in competitive factors
affecting the Company including the inability to obtain new customers or retain
existing customers; (iv) changes in interest rates and conditions in capital
markets affecting the availability of financing; (v) governmental/regulatory
actions and initiatives and environmental/safety requirements that could result
in escalation of the cost of regulatory compliance and litigation; (vi)
significant changes from expectations in actual capital expenditures and
operating expenses; (vii) changes in foreign trade and monetary policies, laws
and regulations related to foreign operations, political governmental changes,
inflation and exchange rates, taxes and operating conditions; (viii) significant
changes in the Company's relationship with its employees and the potential
adverse effects if labor disputes or grievances were to occur; (ix) significant
changes in tax rates or policies or in the rate of inflation; and (x) changes in
accounting principles or the application of such principles by the Company.
 
     None of the Company, Tekni-Plex or any of their respective agents,
employees or advisors intend or have any duty or obligation to supplement,

incorporated by reference in this Proxy Statement. Neither the Company's nor
Tekni-Plex's independent auditors have examined or compiled such statements or

                             postponements thereof, the persons appointed as
                             proxies will have the discretion to vote or act
                             thereon in accordance with their best judgment,
                             unless authority to do so is withheld in the Proxy.
 
                             If the Special Meeting is adjourned, for whatever
                             reason, the approval of the Merger Proposal shall
                             be considered and voted upon by the stockholders of
                             the Company at the subsequent, reconvened meeting,
                             if any.
 
                             Any Proxy signed and returned by a stockholder may
                             be revoked by such stockholder at any time before
                             it is voted by giving due notice of such revocation
                             to the Secretary of the Company (65 Railroad

                             other affirmative action as aforementioned will not
                             constitute a revocation of a Proxy. See "The
                             Special Meeting -- Voting and Revocation of

                             Agreement and the Merger are fair to and in the
                             best interests of the Company and its stockholders
                             and (ii) recommended that the Company's
                             stockholders approve and adopt the Merger Agreement
                             and the transactions contemplated thereby. In
                             reaching its determination that the Merger
                             Agreement and the Merger are fair to and in the
                             best interests of the Company and its stockholders,
                             the Board considered a number of factors, as more
                             fully described under "The Merger -- Reasons for
                             the Merger; Recommendation of the Board of
                             Directors."
 
Opinion of Schroders.......  Schroders has acted as a financial advisor to the
                             Company in connection with the Merger and has
                             delivered to the Board a written opinion, dated
                             November 11, 1997 (the "Schroders Opinion"), to the
                             effect that, as of the date of such opinion and
                             based upon and subject to certain matters stated
                             therein, the Merger Consideration was fair, from a
                             financial point of view, to the holders of Common
                             Stock other than Tekni-Plex, Sub and their
                             affiliates. The full text of the Schroders Opinion
                             which sets forth the assumptions made, matters
                             considered and limitations on the review
                             undertaken, is attached as Annex III to this Proxy
                             Statement and should be read carefully in its
                             entirety. The Schroders Opinion is directed to the
                             Board and relates only to the fairness of the
                             Merger Consideration to the holders of Common Stock
                             other than Tekni-Plex, Sub and their affiliates,
                             from a financial point of view, does not address
                             any other aspect of the Merger or any related
                             transactions and does not constitute a
                             recommendation to any stockholder of the Company as
                             to how such stockholder should vote at the Special
                             Meeting. See "The Merger -- Opinion of Schroders."

Interests of Certain
Persons in the Merger......  Certain directors and executive officers of the
                             Company may have interests, described herein, that
                             present them with potential conflicts of interest
                             in connection with the Merger. The Board of
                             Directors is aware of such conflicts and considered
                             them in addition to the other matters described
                             under "The Merger -- Reasons for the Merger;
                             Recommendation of the Board of Directors." For
                             information concerning such benefits, see "The
                             Merger -- Interests of Certain Persons in the
                             Merger."
 
Financing the Merger.......  It is expected that financing proceeds aggregating
                             approximately $325 million will be required to
                             consummate the Merger and the transactions
                             contemplated thereby. Such financing will be
                             provided by the incurrence and issuance by
                             Tekni-Plex of a combination of senior secured debt
                             and unsecured senior subordinated debt. Additional
                             fees and expenses of approximately $15 million are
                             expected to be paid by Tekni-Plex from existing
                             cash. See "The Merger -- Financing the Merger."

                             obtaining requisite Company stockholder approval,
                             the termination or expiration of the relevant
                             waiting period under the Hart-Scott-Rodino
                             Antitrust Improvements Act of 1976, as amended (the
                             "HSR Act") (see "The Merger -- Regulatory
                             Approvals"), and the absence of any injunction or
                             other legal restraint prohibiting the consummation
                             of the Merger.

                             Merger are further subject, among other things, to

                             "PS&T Notes") by deleting certain covenants and
                             provisions thereof specified by Tekni-Plex, (ii)
                             the Company causing PS&T to purchase at least a

                             Notes pursuant to PS&T's combined consent
                             solicitation and tender offer for such PS&T Notes
                             (the "Debt Tender Offer"), (iii) the Company
                             eliminating the minority stockholders' interests in
                             PS&T (the "PS&T Minority Interest"), either through
                             purchasing their shares or effecting a short-form
                             merger in accordance with the DGCL, and (iv)
                             Tekni-Plex obtaining sufficient financing on terms

                             Agreement. It is also a condition to the
                             obligations of Tekni-Plex and Sub to effect the
                             Merger that no event occur the effect of which
                             would have or be likely to have a material adverse
                             significance with respect to the value of the
                             Company and its subsidiaries, taken as a whole. See
                             "The Merger Agreement -- Conditions to the Merger."
 
Termination; Certain Fees
and Expenses...............  The Merger Agreement will be subject to termination
                             at any time prior to the Effective Time by the

                             Merger Agreement also will be subject to
                             termination by either Tekni-Plex or the Company if

                             any governmental entity has taken action to
                             prohibit the Merger and such action has become
                             final and non-appealable, the Merger is not

Certain Federal Income Tax
  Consequences.............  The receipt of cash by a stockholder of the Company
                             pursuant to the Merger will be a taxable
                             transaction for federal income tax purposes and may
                             also be taxable under applicable state, local and
                             foreign income and other tax laws. In general, a
                             stockholder will recognize gain or loss for federal
                             income tax purposes in an amount equal to the
                             difference between the adjusted tax basis of his,
                             her or its Common Stock and the amount of cash
                             received in exchange therefor in the Merger. Such

                             or loss generally will be capital gain or loss if
                             the Common Stock is a capital asset in the hands of
                             such stockholder, generally will be mid-term gain
                             or loss if the holding period for the Common Stock
                             is more than one year but not more than 18 months
                             at the Effective Time and generally will be
                             long-term capital gain or loss if the holding
                             period is more than 18 months at the Effective
                             Time. See "The Merger -- Certain Federal Income Tax

                             EACH STOCKHOLDER, IT IS RECOMMENDED THAT HOLDERS OF
                             COMMON STOCK CONSULT THEIR TAX ADVISORS CONCERNING
                             THE FEDERAL (AND ANY STATE, LOCAL AND FOREIGN) TAX
                             CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR

                              THE SPECIAL MEETING
 
GENERAL
 
     This Proxy Statement is being furnished to holders of Common Stock in
connection with the solicitation of Proxies by and on behalf of the Board for
use at the Special Meeting to be held at 10:00 a.m., local time, on February 25,
1998, at the Saddle Brook Marriott Hotel, located on the Garden State Parkway at
the intersection with Interstate Highway 80, Saddle Brook, New Jersey 07663, and
at any adjournments or postponements thereof.
 
MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING
 
     At the Special Meeting, the stockholders of the Company will consider and
vote on the Merger Proposal. The Merger Agreement is attached to this Proxy
Statement as Annex I. See "The Merger" and "The Merger Agreement." The Board of
Directors has determined that the Merger Agreement and the Merger are fair and
in the best interests of the Company and its stockholders, has unanimously
approved the Merger Agreement and recommends a vote FOR approval and adoption of
the Merger Proposal. See "The Merger -- Background of the Merger" and
"-- Reasons for the Merger; Recommendation of the Board of Directors."
 
REQUIRED VOTES
 
     The approval of the Merger Proposal will require the affirmative vote of
the holders of a majority of the shares of the Common Stock entitled to vote at
the Special Meeting, provided a quorum is present. The Affiliated Stockholders,
in their capacity as such, have agreed, pursuant to the terms of the Stockholder
Voting Agreement, to vote all of the Subject Shares, during the term of the
Stockholder Voting Agreement, in favor of the Merger Proposal. As of the Record
Date, the Affiliated Stockholders owned, beneficially and/or of record, an
aggregate of 2,666,767 shares of Common Stock, constituting approximately 9% of
the outstanding shares of Common Stock entitled to vote at the Special Meeting.
A copy of the Stockholder Voting Agreement is attached to this Proxy Statement
as Annex II. See "The Stockholder Voting Agreement."
 
     As of the Record Date, directors and executive officers of the Company,
including the Affiliated Stockholders, beneficially owned an aggregate of
5,774,681 shares of Common Stock (approximately 18% of the outstanding shares).
All of the directors and executive officers of the Company have indicated that
they intend to vote their shares of Common Stock in favor of the Merger
Proposal. As discussed above, the Affiliated Stockholders have agreed to vote
their respective Subject Shares in favor of the Merger Proposal pursuant to the
terms of the Stockholder Voting Agreement. See "Security Ownership of Certain
Beneficial Owners and Management."
 
VOTING AND REVOCATION OF PROXIES
 
     This Proxy Statement is being furnished to stockholders of record at the
close of business on the Record Date in connection with the solicitation of
Proxies by and on behalf of the Board for use at the Special Meeting. All shares
of Common Stock which are represented at the Special Meeting by a properly
executed Proxy received and not duly and timely revoked will be voted at the
Special Meeting in accordance with the instructions contained therein. If a
Proxy is signed and returned without indicating any voting instructions, shares
of Common Stock represented by such Proxy will be voted FOR the Merger Proposal.
The Board of Directors is not currently aware of any business to be acted upon
at the Special Meeting other than as described herein. If, however, other
matters are properly brought before the Special Meeting or any adjournments or
postponements thereof, the persons appointed as proxies will have the discretion
to vote or act thereon in accordance with their best judgment, unless authority
to do so is withheld in the Proxy. The persons appointed as proxies will not
exercise their discretionary voting authority to vote any such Proxy in favor of
any adjournments or postponements of the Special Meeting if instruction is given
to vote against the approval of the Merger Proposal.
 
     A Proxy signed and returned by a stockholder may be revoked prior to its
being voted by (i) delivering to the Secretary of the Company, at or before the
Special Meeting, a written instrument bearing a later date than
 
                                       11
<PAGE>   19
 
the Proxy that by its terms revokes the Proxy, (ii) duly executing a subsequent
Proxy relating to the same shares and delivering it to the Secretary of the
Company at or before the Special Meeting or (iii) attending the Special Meeting
and giving notice of revocation to the Secretary of the Company or in open
meeting prior to the Proxy being voted (although attendance at the Special
Meeting without taking other affirmative action as aforementioned will not
constitute a revocation of a Proxy). Any written instrument revoking a Proxy
must be received before the taking of the votes at the Special Meeting and
should be sent to: PureTec Corporation, 65 Railroad Avenue, Ridgefield, New
Jersey 07657, Attention: Secretary.
 
RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM
 
     January 6, 1998 has been fixed as the Record Date for the determination of
the holders of Common Stock entitled to notice of, and to vote at, the Special
Meeting. Only holders of Common Stock at the close of business on the Record
Date will be entitled to notice of, and to vote at, the Special Meeting. At the
close of business on the Record Date, there were 31,272,372 shares of Common
Stock outstanding and entitled to vote at the Special Meeting, held by
approximately 978 stockholders of record. The presence, in person or by properly
executed Proxy, of the holders of a majority of the outstanding shares of Common
Stock is necessary to constitute a quorum at the Special Meeting. Shares of
Common Stock represented by Proxies that are marked "abstain" or that are not
marked as to any particular matter or matters and Proxies relating to "street
name" shares that are voted by brokers will be counted as shares present for
purposes of determining the presence of a quorum on all matters.
 
     Holders of Common Stock on the Record Date are entitled to one vote per
share of Common Stock, exercisable in person or by properly executed Proxy, upon
each matter properly submitted for the vote of stockholders at the Special
Meeting. Abstentions and broker non-votes ("street name" shares for which
brokers do not receive specific voting instructions from beneficial owners) will
not be counted as votes cast in favor of the Merger Proposal. Because the vote
on the Merger Proposal requires the approval of a majority of the shares of
Common Stock entitled to vote at the Special Meeting, abstentions and broker
non-votes will have the same effect as a negative vote on the Merger Proposal.
 
APPRAISAL RIGHTS
 
     Holders of Common Stock on the Record Date who do not vote in favor of
approving and adopting the Merger Agreement (including those who abstain with
respect to the Merger Proposal and those who do not provide specific voting
instructions to brokers who hold their shares of Common Stock in "street name")
and who otherwise comply with the applicable statutory procedures of Section 262
of the DGCL will be entitled to appraisal rights under the DGCL in connection
with the Merger. Stockholders of the Company who vote in favor of approving and
adopting the Merger Agreement, including stockholders who return a signed Proxy
without indicating any voting instructions as to the Merger Proposal, however,
will thereby waive their appraisal rights. The full text of Section 262 of the
DGCL is attached as Annex IV to this Proxy Statement. See "The
Merger -- Appraisal Rights" for a further discussion of such rights and legal
consequences of voting shares of Common Stock in favor of the Merger Proposal.
 
SOLICITATION OF PROXIES
 
     The Company will bear the cost of solicitation of Proxies and the cost of
printing and mailing this Proxy Statement. In addition to solicitation by mail,
the Company's directors, officers and employees may also solicit Proxies from
stockholders of the Company by telephone, telegram or personal interview. Such
directors, officers and employees will not be additionally compensated for any
such solicitation but may be reimbursed for reasonable out-of-pocket expenses in
connection therewith. Arrangements will also be made with brokerage houses and
other fiduciaries, custodians and nominees for the forwarding of solicitation
material to the beneficial owners of shares of Common Stock held of record by
such persons and the Company will reimburse such brokerage houses, fiduciaries,
custodians and nominees for their reasonable out-of-pocket expenses in
connection therewith. MacKenzie will assist in the solicitation of Proxies by
the Company for an estimated fee of $7,500, plus reasonable out-of-pocket
expenses.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
     During the early part of 1997, the Company began to consider alternative
strategies designed to maximize stockholder value. This strategic review was
prompted principally by the views of management and the Board of Directors that
future growth in sales and net income was unlikely without major changes in the
Company's complex and restrictive capital structure. Management expected that
the then-outstanding 17% PS&T Minority Interest, which arose out of the issuance
of warrants as part of PS&T's leveraged buyout financing in 1987, would result
in increasing deductions from net income in future years under applicable
accounting principles. The PS&T Minority Interest was also viewed as being a
deterrent to successfully attracting additional equity investment at the PureTec
level. The limitations imposed by the Indenture governing the PS&T Notes (the
"PS&T Indenture") restricts the amount of additional indebtedness that PS&T can
incur, including for working capital purposes. These limitations were
constraining the amount of inventory that PS&T could maintain and were likely to
continue to limit the Company's ability to increase sales. Lastly, the Company's
highly leveraged capital structure would make acquisitions of businesses with
complementary product lines difficult.
 
     Accordingly, in March 1997 the Company began discussing a retainer
arrangement with Schroders for the provision of financial advice regarding one
or more potential strategic and financial actions. These actions were to include
reducing or eliminating the PS&T Minority Interest; recapitalizing the Company
through an equity investment by an outside investor, the proceeds of which would
be applied to reduce the Company's outstanding indebtedness; soliciting consents
to modify the covenants in the PS&T Indenture; refinancing the PS&T Notes; or
soliciting interest by third parties in a business combination with the Company.
The Company and Schroders executed an engagement letter for such retention on
March 17, 1997. The engagement letter granted to Schroders a right of first
refusal to act as financial advisor in the event that a business combination
involving the Company was pursued. At the time of Schroders' retention, the
Board of Directors had not approved, or instructed management to pursue, any one
of the foregoing alternatives in preference to another.
 
     At a meeting held on May 1, 1997, the Board of Directors authorized
management to proceed with a private exchange offer whereby the Company, through
its wholly-owned subsidiary, Ozite, offered to exchange two new shares of Common
Stock for each share of outstanding PS&T common stock held by accredited
investors who beneficially owned 1,000 or more shares of PS&T common stock. This
exchange offer, for which Schroders acted as dealer manager, was commenced on
May 12, 1997. On the same date, the Company publicly disclosed the retention of
Schroders. The private exchange offer was concluded on June 27, 1997 and
resulted in a reduction of the PS&T Minority Interest to approximately 4% of the
outstanding PS&T common stock.
 
     Commencing in late June and continuing until mid-August 1997, Schroders, on
behalf of the Company, contacted 31 parties regarding their potential interest
in exploring a $20-$40 million dollar equity investment in the Company
("Financial Investors"). Schroders also contacted 20 parties regarding their
potential interest in acquiring the Company ("Strategic Investors"). The Company
executed confidentiality agreements with 24 potential investors, and, beginning
on July 10, 1997, sent to these parties a confidential information memorandum
containing business and financial information about the Company. This memorandum
contained management's projections of the Company's future operating results as
described herein under "Certain Projections of Future Operating Results."
 
     On July 30, 1997, Tekni-Plex executed a confidentiality and two-year
standstill agreement with the Company. Pursuant to the standstill provisions of
this agreement, Tekni-Plex agreed, among other things, that it would not acquire
(subject to certain exceptions), directly or indirectly, any securities or
property of the Company unless the Board of Directors approved such acquisition.
The next day, Tekni-Plex received a copy of the confidential information
memorandum, and representatives of Tekni-Plex attended a presentation by the
Company's management concerning the business of the Company.
 
                                       14
<PAGE>   22
 
     From mid-August until mid-September 1997, seven potential Financial
Investors and Strategic Investors, including Tekni-Plex, conducted due diligence
investigations of the Company, including facility visits and additional
management presentations. During the week of September 15, 1997, six potential
Financial Investors and Strategic Investors submitted written indications of
interest to Schroders concerning possible transactions with the Company.
 
     On September 18, 1997, the Board of Directors met to receive a report from
Schroders concerning the indications of interest. Schroders advised the Board of
Directors that four Financial Investors had indicated an interest in making an
investment in newly-issued Common Stock or convertible preferred stock of the
Company in amounts ranging from $20 million to $70 million. The price per share
of Common Stock indicated in these four proposals ranged from $1.50 to $2.50 per
share (subject in one case to reduction if the average trading price of the
Common Stock as determined over the 60-day period following the public
announcement of the investment was lower than $2.50 per share). These proposals
would have resulted in a Financial Investor initially owning between
approximately 28% and 47% of the outstanding Common Stock, with no commitment by
such Financial Investor to make any proposal to the other holders of Common
Stock concerning the purchase of their shares.
 
     Tekni-Plex submitted a preliminary and conditional proposal for the
potential acquisition of 100% of the Common Stock for a price in the range of
$3.30-$3.50 per share. Tekni-Plex proposed to conduct an all-cash tender offer
followed by a merger in which each untendered share of Common Stock would be
converted into the right to receive an amount in cash equal to the amount per
share paid by Tekni-Plex in the tender offer. In previous discussions with
Schroders on September 12, 1997, Tekni-Plex had indicated an interest in
submitting a proposal having a price range of $3.10-$3.40 per share, but revised
this range upward following further discussions with Schroders. One other
Strategic Investor submitted an indication of interest in a purchase of 100% of
the Common Stock at a cash price of $2.60 per share.
 
     At the September 18 meeting, the Board of Directors discussed all of the
indications of interest at length. Counsel for the Company advised the Board of
Directors as to the legal considerations which the Board must take into account
in evaluating the indications of interest, including those applicable in the
event of a change of control of the Company.
 
     Tekni-Plex's preliminary proposal was subject to various conditions,
including the receipt of financing for the transaction, the satisfactory
completion of additional due diligence by Tekni-Plex and its financial advisor,
J.P. Morgan Securities, Inc., and the development of acceptable definitive
documentation. Tekni-Plex also requested the exclusive right to pursue a
transaction with the Company.
 
     At the conclusion of the meeting, the Board of Directors authorized and
directed management and Schroders to grant Tekni-Plex the exclusive right until
October 17, 1997 (the "Exclusivity Period") to negotiate with the Company in
order to submit a firm proposal, complete additional due diligence activities,
and arrange for firm financing commitments for funding the transaction. The
Board of Directors also instructed Schroders to attempt to obtain an increase in
the price range contained in the Tekni-Plex preliminary proposal to $3.55-$3.60
per share.
 
     Following negotiations between counsel to the Company and counsel to
Tekni-Plex concerning the terms of such a grant of exclusivity, on September 24,
1997, Tekni-Plex accepted the grant of exclusivity set forth in a letter from
the Company to Tekni-Plex dated September 23, 1997 (the "Exclusivity Letter").
The Exclusivity Letter provided, among other things, that during the Exclusivity
Period neither the Company nor its officers, directors or advisors would
negotiate with or solicit, initiate or encourage the submission of any proposal
or offer from any person other than Tekni-Plex with respect to any competing
transaction, provided that the Board of Directors retained the ability to
respond to or negotiate in respect of unsolicited proposals or offers concerning
a competing transaction consistent with its fiduciary duties. From the date of
the Exclusivity Letter until the announcement of the execution of the Merger
Agreement, neither the Company nor its advisors received any such proposals or
offers.
 
     During the initial Exclusivity Period, Tekni-Plex and its financial, legal,
accounting and environmental advisors conducted additional due diligence
investigations of the Company. Pursuant to the terms of the
 
                                       15
<PAGE>   23
 
Exclusivity Letter, on October 2, 1997, counsel for Tekni-Plex delivered to the
Company a proposed form of Merger Agreement. On October 9, 1997, forms of
Commitment Letters (as defined below under "-- Financing the Merger") for
financing necessary to fund the Merger were delivered to the Company by Morgan
Guaranty Trust Company of New York (together with J.P. Morgan Securities Inc.,
"J.P. Morgan"). On October 9, 1997, an initial set of comments on the draft form
of Merger Agreement was delivered to Tekni-Plex's counsel by counsel to PureTec.
During this period, Schroders and J.P. Morgan had a number of discussions as to
the terms and conditions of the Commitment Letters and as to the sufficiency of
the financing provided for thereunder.
 
     On October 13, 1997, a meeting of the Board of Directors was held for the
purpose of informing the directors as to the status of the Tekni-Plex
discussions. On October 17, 1997, the Company received a letter from Tekni-Plex
requesting an extension of the Exclusivity Period to October 31, 1997 in order
to continue due diligence activities. The letter stated that a firm offer from
Tekni-Plex would include, as conditions to the closing of its tender offer,
completion of the Debt Tender Offer and elimination of the PS&T Minority
Interest. Tekni-Plex stated that these actions were required in order that
certain upstream guarantees of Tekni-Plex's 11 1/4% Senior Subordinated Notes
due 2007 (the "Tekni-Plex Notes") could be made by the Company and its
subsidiaries in compliance with the Indenture governing the Tekni-Plex Notes
(the "Tekni-Plex Indenture").
 
     A regularly-scheduled meeting of the Board of Directors was held on October
17, 1997. As a result of discussions at this meeting, including a report from
Schroders as to its discussions with J.P. Morgan concerning the Commitment
Letters, management was authorized to send a response to the October 17
Tekni-Plex letter that conditioned the Company's willingness to proceed with
further discussions on, among other things, the receipt of comfort from
Tekni-Plex and J.P. Morgan that sufficient financial resources would be made
available to complete the Merger in the event that it is necessary to refinance
the debt outstanding under the Tekni-Plex Indenture.
 
     During the following several days, additional negotiations and discussions
among the Company, Tekni-Plex and their advisors occurred with respect to a
number of matters, including continuing due diligence activities, analysis of
the financing requirements of the Merger, development of a mutually acceptable
employee severance plan, and various terms of the Merger Agreement. On October
21, 1997, Tekni-Plex delivered a letter to the Company stating that it had
arranged for an additional financing commitment from J.P. Morgan to provide for
the repurchase of the Tekni-Plex Notes if necessary to consummate the Merger and
the Related Transactions. The Board of Directors, at a meeting held on October
21, 1997, authorized the extension of the Exclusivity Period until October 31,
1997 to permit the continuation of due diligence activities and negotiations on
various terms of the draft Merger Agreement and the draft Commitment Letters.
 
     On October 24, 1997 the Company's counsel delivered to counsel for
Tekni-Plex a second set of comments on the draft Merger Agreement. These
comments were discussed at a meeting among representatives of the Company,
Tekni-Plex and their legal and financial advisors on October 27, 1997. Also on
October 27, counsel for Tekni-Plex delivered to the Company an initial draft of
the Stockholder Voting Agreement.
 
     At the October 27 meeting, the Company requested that Tekni-Plex consider
making a loan to the Company that would assist the Company with its working
capital needs in the period prior to completion of the Merger. Following this
meeting, Tekni-Plex indicated its willingness to consider a loan to the Company
of up to $5 million, to be structured as a convertible note, provided that the
Company agreed to restrictions regarding the making of capital expenditures and
cash management in addition to those contained in the then-current draft of the
Merger Agreement. In light of certain provisions in the Tekni-Plex Indenture,
Tekni-Plex also requested that the tender offer structure it had previously
proposed be replaced by a cash merger transaction that would follow a vote of
the Company's stockholders approving the Merger.
 
     On October 31, 1997, the Board of Directors met and was updated by
management and its financial and legal advisors on the status of negotiations
with Tekni-Plex. The Board authorized management to continue exclusive
negotiations with Tekni-Plex as long as progress was being made on resolving
open issues, including
 
                                       16
<PAGE>   24
 
the terms of the Commitment Letters, the Convertible Note, severance plan
arrangements and the Merger Agreement. Also on October 31, 1997, the Company
received a draft term sheet for the Convertible Note from counsel to Tekni-Plex.
 
     In the days following the October 31, 1997 Board of Directors meeting,
representatives of the Company and Tekni-Plex were in regular contact to
complete the due diligence process and to negotiate other aspects of the
proposed transaction. Tekni-Plex and the Company reached agreement in principle
on the terms of severance plan arrangements, including the stay bonus agreements
for certain members of management described under "-- Interests of Certain
Persons in the Merger-Severance Arrangements" and "-- Employment and Consulting
Arrangements" below. Also, direct discussions occurred between Tekni-Plex, the
officers and directors whom Tekni-Plex had proposed be parties to the
Stockholder Voting Agreement, and counsel to certain of such officers and
directors. Following these discussions, two of the Company's directors, Peter R.
Harvey and John J. Harvey, declined to become parties to the Stockholder Voting
Agreement because they desired to maintain liquidity with respect to their
shares of Common Stock for personal reasons and, in the case of Peter R. Harvey,
becoming a party to the Stockholder Voting Agreement would have been
inconsistent with an existing pledge of such shares. However, the directors and
executive officers of the Company, including John J. Harvey, and Peter R. Harvey
have indicated that they intend to vote their shares of Common Stock in favor of
the Merger Proposal.
 
     On November 11, 1997, a meeting of the Board of Directors took place. All
directors were present. At the meeting, Schroders made a presentation to the
Board concerning the analysis of the terms of the Tekni-Plex proposal as such
terms had been further developed and defined since the Exclusivity Letter was
signed. Schroders stated that Tekni-Plex was prepared to enter into a merger
agreement with the Company that provided for cash payments to the holders of
common stock of $3.50 per share. Schroders also stated that it had been unable
to negotiate any increase in price with Tekni-Plex. Schroders then engaged in a
lengthy and thorough discussion with the Board regarding its findings which are
summarized below under "-- Opinion of Schroders." Schroders further stated,
based upon the information made available to it, that the amount of financing to
be provided pursuant to the Commitment Letters appeared to be adequate for the
consummation of the Merger and the related transactions. At the conclusion of
this discussion, Schroders stated that it would be prepared to deliver an
opinion to the Board to the effect that the Merger Consideration was fair, from
a financial point of view, to the holders of Common Stock other than Tekni-Plex,
Sub and their affiliates, subject to the limitations set forth below under
"-- Opinion of Schroders."
 
     Following the Schroders' presentation, counsel to the Company reported to
the Board that the parties had negotiated nearly final drafts of the Merger
Agreement, the Stockholders Agreement, the Convertible Note and, with the
participation of J.P. Morgan, the Commitment Letters. Counsel reviewed the
responsibilities of the Board of Directors in considering a transaction that
would involve a change of control of the Company, and discussed the terms of the
Merger Agreement, copies of which had been previously distributed to Board
members. The Board also considered the interests of Messrs. Broling, Gans and
Katz, as directors who are also members of management, in the transaction. These
interests consist of such persons' eligibility to participate in severance and
stay bonus arrangements and, in the case of Mr. Broling, the consulting
agreement described under "-- Interests of Certain Persons in the
Merger -- Severance Arrangements" and "-- Employment and Consulting
Arrangements".
 
     After thorough discussion of all factors that it deemed relevant to its
decision, including those noted below under "-- Reasons for the Merger;
Recommendation of the Board of Directors," the Board unanimously voted to
approve the Merger and to recommend that the Company's stockholders approve and
adopt the Merger Agreement and the transactions contemplated thereby.
 
     Following the Board meeting, representatives of the Company, Tekni-Plex and
their legal and financial advisors finalized, executed and delivered the Merger
Agreement, the Stockholder Voting Agreement and the Convertible Note, and J.P.
Morgan executed the Commitment Letters and delivered them to Tekni-Plex. On
November 12, 1997, the Company and Tekni-Plex issued a joint press release
announcing the proposed Merger, and the Company issued the Convertible Note to
Tekni-Plex.

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The Board has determined that the Merger Agreement and the Merger are fair
to and in the best interests of the Company and its stockholders and has
unanimously approved and adopted the Merger Agreement. Accordingly, the Board
recommends that stockholders vote FOR approval and adoption of the Merger
Agreement.
 
     In reaching its determination that the Merger Agreement and the Merger are
fair to and in the best interests of the Company and its stockholders, the Board
consulted with the Company's legal and financial advisors and considered the
following principal factors which were material to the Board's decision:
 
          (i) The premium provided by the Merger Consideration over the
     historical market prices for the Common Stock, including the fact that the
     Merger Consideration represents a premium of 29% over the $2.72 per share
     last sale price of the Common Stock on November 11, 1997, the trading day
     preceding the date on which the execution of the Merger Agreement was
     publicly announced and a premium of 94% over the six-month average stock
     price of $1.80 for the period ending November 11, 1997. See "Market Prices
     of Common Stock."
 
          (ii) The provision by Tekni-Plex to the Company of executed Commitment
     Letters from Morgan Guaranty Trust Company of New York, which has committed
     to provide 100% of the funds necessary to finance (x) the Merger, (y) each
     of the Debt Tender Offer, the elimination of the PS&T Minority Interest,
     the repayment or repurchase of certain indebtedness of the Company and the
     payments to be made in connection with the cancellation of certain Options
     (collectively, the "Related Transactions") and (z) the payment of certain
     fees and expenses incurred in connection with the Merger and the Board's
     views regarding the likelihood that Tekni-Plex would be able to complete
     the Merger on a timely basis.
 
          (iii) The Schroders Opinion to the effect that, based upon and subject
     to certain matters stated therein, the Merger Consideration is fair, from a
     financial point of view, to the holders of Common Stock other than
     Tekni-Plex, Sub and their affiliates and the presentation of Schroders at
     the November 11, 1997 Board meeting in connection with its opinion. See
     "-- Opinion of Schroders."
 
          (iv) The current and prospective economic and competitive environment
     in which the Company operates.
 
          (v) The history of prior efforts to pursue alternatives for maximizing
     stockholder value, as described under "-- Background of the Merger,"
     particularly the fact that, based upon the discussions described therein,
     none of such alternatives, even if successfully carried to completion,
     would have resulted in per-share cash consideration either directly to the
     holders of Common Stock or to the Company as high as the Merger
     Consideration.
 
          (vi) The fact that the Merger Agreement requires that the Merger be
     submitted to the stockholders of the Company for approval, which allows for
     an informed vote of stockholders on the merits of the transaction without
     any potentially coercive transaction structure and the fact that the Merger
     Agreement provides that it may be terminated by the Company if such
     approval is not received.
 
          (vii) The fact that the Merger Consideration to be received by
     stockholders of the Company is cash.
 
          (viii) The other terms and conditions of the Merger Agreement,
     including (x) those relating to the fee of $10 million and expense
     reimbursements (for documented out-of-pocket expenses and fees incurred in
     connection with the Merger up to a maximum of $5 million) to Tekni-Plex
     payable upon the termination of the Merger Agreement as a result of
     competing offers, the aggregate amount of which would not, in the Board's
     judgment, preclude a third party from making an offer that was materially
     more favorable to the Company's stockholders and (y) those relating to the
     ability of the Board to consider unsolicited offers from third parties
     prior to the Effective Time.
 
          (ix) The $5 million loan provided by Tekni-Plex to the Company, in
     return for the Convertible Note, which has assisted the Company and PS&T in
     meeting expected cash requirements prior to the completion of the Merger.
 
                                       18
<PAGE>   26
 
          (x) The Board's knowledge of the business, operations, properties,
     assets, financial condition and operating results of the Company.
 
     The foregoing factors were deemed by the Board to outweigh that aspect of
Tekni-Plex's offer viewed by the Board as more unfavorable, which was that
Tekni-Plex's obligation to consummate the Merger is contingent upon receipt of
financing sufficient to provide 100% of the necessary funds to complete the
actions described in clause (ii) above.
 
     The foregoing discussion of the information and factors discussed by the
Board is not meant to be exhaustive but is believed to include all material
factors considered by the Board. In view of the variety of factors considered in
connection with its evaluation of the Merger, the Board did not find it
practicable to, and did not quantify or otherwise attempt to assign any
particular weight to the various factors that it considered in reaching its
determination that the Merger Agreement and the Merger are fair to and in the
best interests of the Company and its stockholders. In addition, individual
members of the Board may have given different weight to different factors. As a
result of its consideration of the foregoing and other relevant considerations,
the Board determined that the Merger Agreement and the Merger are fair to and in
the best interests of the Company and its stockholders and unanimously approved
and adopted the Merger Agreement.
 
OPINION OF SCHRODERS
 
     In connection with its consideration of the proposed Merger, the Company
requested that Schroders advise the Board with respect to the fairness, from a
financial point of view, of the consideration to be received by the holders of
Common Stock other than Tekni-Plex, Sub and their affiliates in the Merger. On
November 11, 1997, at a meeting of the Board held to evaluate the proposed
Merger, Schroders reviewed with the Board the financial analyses performed by
Schroders and delivered to the Board an oral opinion (which opinion was
subsequently confirmed by delivery of a written opinion, dated November 11,
1997) to the effect that, as of the date of such opinion and based upon and
subject to certain matters stated therein, the Merger Consideration was fair,
from a financial point of view, to the holders of Common Stock of the Company
other than Tekni-Plex, Sub and their affiliates. The full text of the Schroders
Opinion, dated November 11, 1997, which sets forth the assumptions made, matters
considered and limits of the review undertaken, is included as Annex III to this
Proxy Statement and is incorporated herein by reference. Schroders has consented
to the inclusion of the full text of the Schroders Opinion as Annex III to this
Proxy Statement. THE SUMMARY OF SCHRODERS' OPINION SET FORTH BELOW IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION. STOCKHOLDERS ARE
URGED TO READ THE SCHRODERS OPINION CAREFULLY IN ITS ENTIRETY.
 
     No limitations were imposed by the Board on the scope of Schroders'
investigation or the procedures to be followed by Schroders in rendering its
opinion. In arriving at its opinion, Schroders, among other things: reviewed a
draft, dated November 4, 1997, of the Merger Agreement; reviewed drafts of the
Commitment Letters received by Tekni-Plex in connection with the Financing (as
defined herein); reviewed the Company's Annual Report on Form 10-K filed with
the Commission for the fiscal year ended July 31, 1996, including the audited
consolidated financial statements of the Company included therein; reviewed a
draft of the Company's Annual Report on Form 10-K for the fiscal year ended July
31, 1997; reviewed historical financial results of the Company by subsidiary and
operating division prepared by management; reviewed forecasts and projections
for the Company prepared or supplied by management of the Company for the fiscal
years ending July 31, 1998 through July 31, 2000 (the "Company Financial
Forecasts"); held discussions with the Company's management regarding the
business, operations and prospects of the Company and each of its subsidiaries
and operating divisions; visited the Company's facilities in Ridgefield and
Rockaway, New Jersey; advised the Company regarding other proposed transactions
during the period from May 1997 to September 1997, and initiated contacts with
several potential investors in, and acquirors of, the Company; performed various
valuation analyses, as deemed by it to be appropriate, of the Company using
generally accepted analytical methodologies, including (i) the application to
the financial results of the Company of the public trading multiples of
companies which were deemed by it to be comparable, (ii) the application to the
financial results of the Company of the multiples reflected in recent mergers
and acquisitions for businesses which were deemed comparable, (iii) a discounted
cash flow analysis of the Company's operations, (iv) a premium analysis and (v)
a leveraged buyout analysis; reviewed the historical trading prices and volumes
of the
 
                                       19
<PAGE>   27
 
Common Stock; and performed such other financial studies, analyses, inquiries
and investigations as it deemed appropriate. In addition, Schroders took into
account the manner in which the financial terms of the Merger were negotiated by
the Company and Tekni-Plex, as well as the results of the extended solicitations
of interest by the Company from persons thought likely to have a possible
interest in acquiring or investing in the Company.
 
     In its review and analysis and in formulating its opinion, Schroders
assumed and relied upon, without independent verification, the accuracy and
completeness of all information supplied or otherwise made available to it by
the Company or obtained by Schroders from other publicly available sources, and
upon the assurance of the Company's management that they were not aware of any
information or facts that would make the information provided by it to Schroders
incomplete or misleading. Schroders did not conduct a physical inspection of
certain of the properties and facilities of the Company and its subsidiaries and
did not undertake an independent appraisal of the assets or liabilities
(contingent or otherwise) of the Company nor was Schroders furnished with any
such appraisals.
 
     With respect to financial forecasts and projections for the Company,
Schroders was advised by the Company, and assumed without independent
investigation, that such forecasts and projections had been reasonably prepared
and reflected the best currently available estimates and judgments as to the
expected future financial performance of the Company. The projected financial
information set forth under "Certain Projections of Future Operating Results"
herein is excerpted from the Company Financial Forecasts provided by management
to, and relied upon by, Schroders in its analyses. In the course of analyzing
the Company Financial Forecasts, Schroders excluded the projected effects of
certain proposed capital expenditure projects contemplated by the Company
because of the lack of certainty regarding the timing and funding of such
projects.
 
     Schroders noted that its opinion was necessarily based upon financial,
economic, market and other conditions as they existed and could be evaluated by
Schroders on, and the information made available to it as of, the date of its
opinion. Schroders has disclaimed any undertaking or obligation to advise any
person of any change in any fact or matter affecting its opinion that is brought
to its attention after the date of its opinion. Although Schroders evaluated the
Merger Consideration from a financial point of view, Schroders was not asked to
and did not recommend the specific consideration payable in the Merger, which
was determined through negotiations between the Company and Tekni-Plex.
 
     The Schroders Opinion is for the information of the Board of Directors for
its use in evaluating the fairness from a financial point of view of the Merger
Consideration to the stockholders of the Company other than Tekni-Plex, Sub and
their affiliates. Such opinion does not constitute a recommendation as to any
action the Board of Directors or any stockholder of the Company should take in
connection with the Merger or any aspect thereof. The Schroders Opinion is not
an opinion as to the structure, terms or effect of any other aspect of the
Merger or of any of the transactions contemplated in connection therewith or as
to the merits of the underlying decision of the Company to enter into the Merger
or any such transaction.
 
     In preparing its opinion, Schroders performed a variety of financial and
comparative analyses, including those described below. The summary of such
analyses does not purport to be a complete description of the analyses
underlying the Schroders Opinion or of the presentation by Schroders to the
Board of Directors. The preparation of a fairness opinion is a complex analytic
process involving various determinations as to the most appropriate and relevant
methods of financial analyses and the application of those methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Furthermore, in arriving at its opinion,
Schroders did not attribute any particular weight to any analysis or factor
considered by it, but rather made qualitative judgments as to the significance
and relevance of each analysis and factor. Accordingly, Schroders believes that
its analyses must be considered as a whole and that selecting portions of its
analyses and factors, without considering all analyses and factors, could create
a misleading or incomplete view of the processes underlying the preparation of
its opinion. In its analyses, Schroders made numerous assumptions with respect
to the Company, industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
the Company. The estimates contained in such analyses and the valuation ranges
resulting from any particular analysis are not necessarily
 
                                       20
<PAGE>   28
 
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than those suggested by such analyses.
In addition, analyses relating to the value of businesses or securities do not
purport to be appraisals or to reflect the prices at which businesses or
securities actually may be sold. Accordingly, such analyses and estimates are
inherently subject to substantial uncertainty. The Schroders Opinion and
analyses were only one of many factors considered by the Board in its evaluation
of the Merger and should not be viewed as determinative of the view of the Board
or management of the Company with respect to the Merger Consideration or the
proposed Merger.
 
     The following is a summary of certain analyses performed by Schroders in
connection with its opinion.
 
     Analysis of Comparable Publicly Traded Companies.  Using publicly available
information, Schroders compared selected historical and projected financial and
operating data, and selected stock market data of the Company to the
corresponding data of the following publicly traded manufacturing companies that
Schroders considered reasonably comparable to the Company (collectively, the
"Comparable Companies"): Atlantis Plastics, Inc.; Foamex International Inc.;
O'Sullivan Corporation; A. Shulman, Inc.; and Spartech Corporation.
 
     Schroders performed a market analysis of the Company and the Comparable
Companies using closing market prices as of October 31, 1997. In connection with
such analysis, Schroders analyzed (i) the market value of each of the Comparable
Companies and the Company as multiples of earnings per share for the last twelve
months ("LTM") and for the twelve months ending nearest to the Company's fiscal
year end of July 31, 1998, (ii) the market value plus total debt minus total
cash ("Enterprise Value") of each of the Comparable Companies and the Company as
multiples of adjusted earnings before interest and taxes ("EBIT") for the last
twelve months and for the twelve months ending nearest to July 31, 1998, and
(iii) the Enterprise Value of each of the Comparable Companies and the Company
as multiples of adjusted earnings before interest, taxes, depreciation and
amortization ("EBITDA") for the last twelve months and for the twelve months
ending nearest to July 31, 1998. Based on this analysis, Schroders calculated an
implied equity value for the Common Stock of between $2.00 and $3.50 per share.
 
     Selected Merger and Acquisition Transaction Analyses.  Schroders analyzed
certain publicly available information relating to selected merger and
acquisition transactions since 1995 of plastics manufacturing companies and
diversified industrial companies with similar leverage and/or growth
characteristics to the Company. Although these transactions were reviewed for
comparison purposes, none of such transactions was considered exactly comparable
to the proposed Merger. Among the transactions analyzed by Schroders were
(target/acquiror): Synergistics Industries Ltd/Geon Co. (October 1997); Hamelin
Group, Inc./Spartech Corp. (September 1996); Carlisle Plastics, Inc./Tyco
International Ltd. (September 1996); Automotive Industries Holding/Lear Seating
Corp. (August 1995); IMO Industries/Constellation Capital (August 1997); Core
Industries/United Dominion Industries Ltd. (July 1997); Sudbury Inc./Intermet
Corp. (November 1996); Newflo Corporation/Precision Castparts Corporation (July
1996); and Salem Corp./ Salem Group Inc. (September 1996).
 
     With respect to each of the selected transactions analyzed, Schroders
computed the equity costs (where applicable, the offer per share multiplied by
total common shares outstanding (the "Equity Cost")) and the adjusted price (the
Equity Cost plus latest reported total debt, capitalized leases, preferred stock
and minority interest minus total cash and cash equivalents) paid in such
transactions and divided the adjusted price by the acquired company's LTM EBITDA
and EBIT and the acquired Company's projected EBITDA and EBIT for the next
fiscal year ending subsequent to the acquisition. These analyses produced
average ranges of purchase price multiples of between 6.5x and 8.0x LTM EBITDA,
9.0x and 11.5x LTM EBIT, 6.0x and 7.0x projected EBIDTA and 8.5x and 9.5x
projected EBIT. Based on these analyses, Schroders calculated an implied equity
value for the Common Stock of between $2.00 and $3.50 per share.
 
     Discounted Cash Flow Analysis.  Schroders performed a discounted cash flow
analysis of the Company based on the Company Financial Forecasts on financial
forecasts for the fiscal years 2001 and 2002 based upon management's assumptions
of future financial performance. A discounted cash flow analysis is a
traditional valuation methodology used to derive a valuation of a corporate
entity by calculating the estimated future free cash flows of such corporate
entity and discounting such cash flow results back to the present.
 
                                       21
<PAGE>   29
 
     In its discounted cash flow analyses, Schroders discounted the stream of
free cash flows back to December 31, 1997 at discount rates ranging from 12% to
14%. To estimate the terminal value of the Company at the end of the Company's
financial forecast period, Schroders applied terminal multiples ranging from
6.0x to 8.0x to the Company's average EBITDA for the five years ending in 2002,
and discounted such value estimates back to December 31, 1997 at discount rates
ranging from 12% to 14%. Schroders then added the present values of the free
cash flows to the present values of the terminal values, subtracted existing
indebtedness and added existing cash and cash equivalents to derive a range of
implied equity values. Based on the Company Financial Forecasts and management
assumptions, this analysis implied a range of equity values for the Common Stock
of between $2.50 and $3.50 per share.
 
     Premium Analysis.  Schroders analyzed the premiums paid over the stock
price of acquired companies in selected merger transactions since 1992, based on
stock prices one day, one week and four weeks prior to the announcement of the
transaction. This analysis demonstrated that, on average, the acquired company
received a 33%, 38% and 44% premium over its stock price one day, one week and
four weeks prior to the announcement of a transaction, respectively. Schroders
then compared these results with the premiums implied by the proposed Merger
over the Company's stock price immediately preceding Tekni-Plex's initial offer
in September 1997. The proposed Merger implies premiums of 78%, 88% and 103%
over the Company's share price one day, one week and four weeks, respectively,
prior to September 18, 1997.
 
     Other Analysis.  Schroders analyzed the feasibility of a leveraged buyout
of the Company. This analysis implied that, based on current market conditions,
a leveraged buyout of the Company was marginally feasible at a price of up to
$2.50 per share. In connection with this analysis, Schroders assumed that (i)
the purchase would be funded with debt to the maximum extent possible (which was
assumed to be 5.0x EBITDA), (ii) the Company would be resold after five years at
a purchase price equal to 7.0x EBITDA, and (iii) the investor would require a
return of 25-30% on its investment.
 
     Pursuant to the terms of Schroders' engagement by the Company, the Company
has agreed, among other things, to pay Schroders for its services in connection
with the Merger an aggregate financial advisory fee equal to 1% of the total
consideration payable in connection with the Merger (including the aggregate
principal amount of the Company's indebtedness), which fee is contingent on
consummation of the Merger. The Company has also agreed to reimburse Schroders
for reasonable out-of-pocket expenses incurred by Schroders in performing its
services, including the reasonable fees and expenses of its outside legal
counsel, and to indemnify Schroders and related persons against certain
liabilities relating to or arising out of its engagement, including certain
liabilities under the federal securities laws.
 
     Schroders, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for estate,
corporate and other purposes. Since 1986, Schroders has provided investment
banking services to the Company for which it has received customary fees. In
addition, in October 1993, Schroders managed the public offering of the PS&T
Notes. The Company selected Schroders as its financial advisor because it is a
nationally recognized investment banking firm that has substantial experience in
transactions similar to the Merger and because of its familiarity with the
Company.
 
     Schroders, in the normal course of its business, trades in securities of
the Company and in the PS&T Notes for its own account and for the accounts of
its customers and, accordingly, may from time to time hold a long or short
position in such securities.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain directors and executive officers of the Company have interests,
described herein, that present them with potential conflicts of interest in
connection with the Merger. The Board of Directors is aware of the conflicts
summarized below and considered them along with the other matters described
under "-- Reasons for the Merger; Recommendation of the Board of Directors."
 
                                       22
<PAGE>   30
 
     Interests in Common Stock and Options.  As of the Record Date, the
executive officers and directors of the Company owned an aggregate of 5,774,681
shares of Common Stock (or 18% of the total outstanding shares of Common Stock).
Shares of Common Stock held by the executive officers and directors of the
Company will be converted into the right to receive the same consideration as
shares of Common Stock held by other stockholders. Accordingly, the aggregate
consideration that will be received upon the consummation of the Merger by the
executive officers and directors of the Company in respect of such shares would
be $20,211,384.
 
     In addition, as of the Record Date, such executive officers and directors
of the Company had the right to acquire 941,300 shares of Common Stock upon the
exercise of Options granted to such executive officers and directors pursuant to
the Option Plans at exercise prices less than the Merger Consideration. Pursuant
to the Merger Agreement, at the Effective Time, each holder of an outstanding
Option granted under either of the Option Plans, including each executive
director and officer, whether or not then vested or exercisable, will be paid by
the Company, promptly upon surrender of such Option, net of applicable
withholding taxes, an amount in cash equal to the product of (i) the excess, if
any, of the Merger Consideration over the applicable exercise price per share of
Common Stock subject to such Option and (ii) the total number of shares of
Common Stock subject to such Option assuming full vesting immediately prior to
the Effective Time. The cash that will be received by the executive officers and
directors of the Company upon the consummation of the Merger pursuant to the
surrender of Options would be approximately $3,294,550. See "The Merger
Agreement -- The Merger -- Options."
 
     Severance Arrangements.  The Company adopted, subject to negotiation of
final documentation with Tekni-Plex concerning such arrangements, a severance
payment plan (the "Severance Plan") that will become effective at the Effective
Time pursuant to which domestic salaried employees of the Company and its
subsidiaries, including certain executive officers of the Company, may receive
separation benefits. Under the Severance Plan, any domestic salaried employee
(including an executive officer) whose employment is terminated as a result of
restructuring changes within one year from the Effective Time (unless the
employee at that time is a party to a separate agreement with the Company that
provides for the payment of a greater amount) is eligible to receive a severance
payment. In order to receive a severance payment, the employee must continue his
or her employment through a separation date to be determined by the Company, and
sign a release of any claim that he or she may have against the Company or
Tekni-Plex or both. The amount of the payment will be based upon the employee's
length of service, position responsibility and current base salary, and will be
calculated at one week of pay per year of service, but shall not be less than a
prescribed number of weeks depending on position title (that is, 26 weeks for
the Chief Operating Officer, the Chief Financial Officer, the Corporate
Secretary, the President and any Vice President of the Company, 20 weeks for any
director or general manager of the Company and between 4 and 16 weeks for other
domestic salaried employees of the Company).
 
     Thomas V. Gilboy, the Chief Financial Officer of the Company, and Gerard R.
Giordano, the Vice President -- Corporate Finance of the Company, have separate
severance agreements with the Company that provide, as long as such agreements
are effective, for severance payments in a greater amount than is provided for
by the Severance Plan. Mr. Gilboy's agreement with the Company, which expires in
May 1998, provides that he shall receive 52 weeks of severance pay, based on
current salary plus a bonus, if he is terminated for any reason other than
cause. Mr. Giordano's agreement with the Company, which expires in July 1999,
provides that he shall receive 52 weeks of severance pay, based on current
salary plus a bonus, if he is terminated for any reason other than cause.
 
     Stockholder Voting Agreement.  Pursuant to the Stockholder Voting
Agreement, the Affiliated Stockholders have, in their capacity as stockholders,
agreed to vote the Subject Shares in favor of the Merger Related Actions and
have granted Tekni-Plex the Tekni-Plex Option to purchase the Subject Shares at
the Exercise Price, in each case, subject to the terms and conditions of the
Stockholder Voting Agreement. See "The Stockholder Voting Agreement."
 
     Stay Bonus and Consulting Arrangements.  To provide incentive for a
successful transition of the Company's ownership, the Company intends to adopt,
prior to the Effective Time, a stay bonus program
 
                                       23
<PAGE>   31
 
covering up to 10 officers and employees of the Company and its subsidiaries
(the "Participating Employees") exclusive of the Chief Executive Officer of the
Company (the "CEO"). If adopted, the stay bonus program shall be adopted
pursuant to documentation satisfactory to each of Tekni-Plex and the Company and
shall provide for (i) the payment of up to $800,000 in the aggregate in a lump
sum to Participating Employees who remain employed by the Company and its
subsidiaries through the forty-fifth day following the Merger (unless earlier
terminated by Tekni-Plex not for cause) and (ii) the payment of up to $400,000
to the CEO if such CEO remains employed by the Company until the Merger. In
addition, the CEO shall be entitled to $150,000 per annum pursuant to and in
accordance with a consulting agreement between the CEO and the Company. It shall
be a condition of each Participating Employee's right to receive a stay bonus
pursuant to the program that such employee not be terminated for cause, that
such employee shall discharge his assigned duties, that such employee shall at
all times promote the interests of the Company and the harmonious transition of
ownership thereof, and that such employee sign a general release of all claims,
as of such date, against the Company and its subsidiaries.
 
     Indemnification and Insurance.  Pursuant to the Merger Agreement, each of
the Surviving Corporation and PS&T will, pursuant to provisions in their
respective certificates of incorporation and by-laws, indemnify and hold
harmless the present and former officers and directors of the Company and PS&T,
respectively, in respect of acts or omissions occurring while such persons are
officers and directors to the same extent as is provided under each of the
Company's and PS&T's, respectively, certificate of incorporation and bylaws in
effect on the date of the Merger Agreement, and Tekni-Plex will not amend,
repeal or modify such provisions in any manner that would adversely affect the
rights thereunder of such persons provided that such indemnification shall be
subject to any limitation imposed from time to time under applicable law.
 
     Tekni-Plex has agreed that, for four years after the Effective Time, it
will cause each of the Surviving Corporation and PS&T, respectively, subject to
certain limitations, to use its best efforts to provide officers' and directors'
liability insurance in respect of acts or omissions occurring prior to the
Effective Time covering each such person currently covered by the Company's and
PS&T's officers' and directors' liability insurance policy on terms with respect
to coverage and amount no less favorable in the aggregate than those of the
applicable policy in effect on the date of the Merger Agreement. See "The Merger
Agreement -- Certain Covenants -- Director and Officer Liability."
 
FINANCING THE MERGER
 
     The Financing.  The estimated aggregate amount of financing required (i) to
pay the Merger Consideration, (ii) to finance the Related Transactions, (iii) to
retire, if necessary, the Tekni-Plex Notes, (iv) to pay related fees and
expenses not to exceed $8 million and (v) to provide undrawn revolving lines of
credit of approximately $40 million will be approximately $480 million (the
"Financing"). Assuming the Tekni-Plex Notes are not retired, the estimated
aggregate amount of financing required to consummate the Merger and the
transactions contemplated thereby is approximately $325 million. The Financing,
as described below, will be provided by a combination of (i) the incurrence by
Tekni-Plex of senior secured debt and (ii) the issuance by Tekni-Plex of
unsecured senior subordinated debt pursuant to either the New Bond Placement or
the Bridge Financing (each as defined below). Additional fees and expenses of
approximately $15 million are expected to be paid by Tekni-Plex out of existing
cash.
 
     Tekni-Plex has received a commitment letter (the "Senior Commitment
Letter") from Morgan Guaranty Trust Company of New York (the "Lender") dated
November 11, 1997 pursuant to which the Lender has committed, subject to the
terms and conditions thereof, to provide up to $255 million of senior secured
financing (the "Senior Financing"). Pursuant to the Senior Financing, Tekni-Plex
will enter into a credit agreement with the Lender and the other lenders named
therein (the "Credit Agreement") providing for (i) a term loan facility (the "A
Term Loan Facility") in an aggregate principal amount of $50 million, (ii) a
second term loan facility (the "B Term Loan Facility" and, together with the A
Term Loan Facility, the "Term Loan Facilities") in an aggregate principal amount
of $115 million and (iii) a revolving credit facility (the "Revolving Facility"
and, together with the Term Loan Facilities, the "Credit Facilities") in an
aggregate principal amount of $90 million, of which at least $40 million is
expected to remain undrawn and available to fund the ongoing working capital
needs and general corporate requirements of Tekni-Plex and its
 
                                       24
<PAGE>   32
 
subsidiaries following the Merger. The allocation of the Lender's commitment
under the Senior Commitment Letter is subject to re-allocation among the Credit
Facilities at the option of the Lender, provided that the aggregate commitment
of up to $255 million shall not change.
 
     Tekni-Plex plans to raise up to $225 million through the issuance and sale
of senior subordinated notes (the "New Bond Placement"). Although the New Bond
Placement is expected to be completed simultaneously with the Merger, in the
event that the Merger is consummated prior to the completion of the New Bond
Placement, Tekni-Plex will utilize the Bridge Financing, as described below, to
fund the amounts that otherwise would have been funded from the proceeds of the
New Bond Placement.
 
     Tekni-Plex has received a commitment letter (the "Bridge Commitment Letter"
and, together with the Senior Commitment Letter, the "Commitment Letters") from
the Lender dated November 11, 1997 pursuant to which the Lender has committed,
subject to the terms and conditions thereof, to provide up to $225 million of
senior subordinated bridge financing (the "Bridge Financing") in the event that
Tekni-Plex is unable to complete the New Bond Placement simultaneously with the
Merger. In the event the Bridge Financing is needed, Tekni-Plex will enter into
a bridge loan agreement (the "Bridge Agreement" and, together with the Credit
Agreement, the "Financing Agreements") with the Lender and any other lenders
named therein.
 
     Loans under the Credit Agreement will be secured by substantially all of
the assets of Tekni-Plex and each of its subsidiaries and loans under the
Financing Agreements will be guaranteed by each of Tekni-Plex and its
subsidiaries. The loans under the Bridge Agreement will be senior subordinated
obligations of Tekni-Plex, subordinated to the borrowings outstanding under the
Credit Agreement and certain other senior obligations of Tekni-Plex. The Credit
Agreement loans will bear interest, at the option of Tekni-Plex, at either (i)
the higher of the prime rate or the federal funds rate plus 1/2 of 1%, in each
case, plus a margin or (ii) a Eurodollar rate plus a margin. Availability of
funds pursuant to the Senior Financing and the Bridge Financing is subject to
the satisfaction of certain customary borrowing conditions and covenants as set
forth in the Commitment Letters and to be set forth in the Financing Agreements.
 
     The Convertible Note.  Concurrently with the execution of the Merger
Agreement, Tekni-Plex purchased a convertible note (the "Convertible Note")
issued by the Company in the amount of $5 million. The loan has assisted the
Company and PS&T in meeting expected cash requirements in the period prior to
completion of the Merger. The Convertible Note bears interest at 13% and is
convertible at any time following the sixtieth day after any termination of the
Merger Agreement into a number of shares of Common Stock having a fair market
value equal to the principal amount of the Note plus accrued interest or in any
event at a base conversion rate of one share of Common Stock per $2.72 of
obligations owed under the Convertible Note. The Company has agreed to file a
registration statement with respect to the Common Stock issuable upon conversion
promptly following any such termination of the Merger Agreement. The Convertible
Note matures on September 30, 1998. The Convertible Note is subject to
prepayment by the Company in cash at any time.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for by Tekni-Plex as a "purchase" in
accordance with generally accepted accounting principles. Therefore, the
aggregate consideration paid by Tekni-Plex in connection with the Merger will be
allocated to the Company's assets and liabilities based upon their fair values,
with any excess being treated as goodwill. The assets and liabilities and
results of operations of the Company will be consolidated into the assets and
liabilities and results of operations of Tekni-Plex subsequent to the
consummation of the Merger.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     In the opinion of Winthrop, Stimson, Putnam & Roberts, the following are,
under currently applicable law, certain United States federal income tax
considerations generally applicable to the Merger. The tax treatment described
herein may vary depending upon each stockholder's particular circumstances and
tax position. Certain stockholders (including insurance companies, tax-exempt
organizations, financial institutions or broker-dealers, foreign corporations,
persons who are not citizens or residents of the United States (the
 
                                       25
<PAGE>   33
 
"U.S."), stockholders who do not hold their shares as capital assets and
stockholders who have acquired their existing stock upon the exercise of options
or otherwise as compensation) may be subject to specials rules not discussed
below. No ruling from the Internal Revenue Service (the "IRS") will be applied
for with respect to the federal income tax consequences discussed herein and,
accordingly, there can be no assurance that the IRS will agree with the
conclusions stated herein. The discussion below is based upon the provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), and regulations,
rulings and judicial decisions thereunder as of the date hereof, and such
authorities may be repealed, revoked or modified so as to result in U.S. federal
income tax consequences different from those discussed below. In addition, this
discussion does not consider the effect of any applicable foreign, state, local
or other tax laws. Each stockholder should consult his, her or its own tax
advisor as to the particular tax consequences to such stockholder of the Merger,
including the applicability and effect of any foreign, state, local or other tax
laws.
 
     The receipt of cash in exchange for Common Stock pursuant to the Merger
will be a taxable transaction for federal income tax purposes and may also be a
taxable transaction under applicable state, local and foreign income and other
tax laws. The tax consequences of such receipt may vary depending upon, among
other things, the particular circumstances of the stockholder. In general, a
stockholder will recognize gain or loss for federal income tax purposes equal to
the difference between the adjusted tax basis of his, her or its Common Stock
and the amount of cash received in exchange therefor in the Merger. Such gain or
loss generally will be capital gain or loss if the Common Stock is a capital
asset in the hands of such stockholder, generally will be mid-term gain or loss
if the holding period for the Common Stock is more than one year but not more
than 18 months at the Effective Time, and generally will be long-term gain or
loss if the holding period for the Common Stock is more than 18 months at the
Effective Time. Generally, for stockholders who are individuals, mid-term gain
will be subject to tax at a maximum rate of 28% and long-term gain will be
subject to a maximum rate of 20%.
 
     The receipt of cash by a stockholder of the Company pursuant to the Merger
may be subject to backup withholding unless the stockholder (i) is a corporation
or comes within certain other exempt categories, or (ii) provides a certified
taxpayer identification number on Form W-9 and otherwise complies with the
backup withholding rules. Backup withholding is not an additional tax; any
amounts so withheld may be credited against the federal income tax liability of
the stockholder subject to the withholding.
 
     THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION
ONLY. DUE TO THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, STOCKHOLDERS ARE URGED
TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE
MERGER, INCLUDING THE EFFECTS OF APPLICABLE STATE, LOCAL OR FOREIGN INCOME OR
OTHER TAX LAWS.
 
REGULATORY APPROVALS
 
     The Merger is subject to the requirements of the HSR Act, and the rules and
regulations thereunder, which provide that certain transactions may not be
consummated until required information and materials are furnished to the
Antitrust Division of the Department of Justice (the "Antitrust Division") and
the Federal Trade Commission (the "FTC") and the requisite waiting period
expires or terminates. The Company and Tekni-Plex made all filings required by
the Antitrust Division and the FTC on December 17, 1997, commencing a thirty-day
waiting period. The FTC granted early termination of the statutory waiting
period effective January 2, 1998. Although the waiting period has expired under
the HSR Act pursuant to early termination, at any time before or after the
Effective Time, the Antitrust Division or the FTC could take such action under
the antitrust laws as it deems necessary or desirable in the public interest, or
certain other persons could take action under the antitrust laws, including
seeking to enjoin the Merger.
 
     On November 17, 1997, the Company made certain filings with the New Jersey
Department of Environmental Protection (the "NJDEP") under the New Jersey
Industrial Site Recovery Act ("ISRA"). With respect to three of its facilities
in New Jersey, the Company has obtained letters of nonapplicability from the
NJDEP. With respect to the other four New Jersey facilities, the Company will
execute a remediation agreement with the NJDEP prior to the Effective Time.

CERTAIN CONSEQUENCES OF THE MERGER
 
     As a result of the Merger, Sub will be merged with and into the Company and
the Company will become a wholly owned subsidiary of Tekni-Plex. Following
consummation of the Merger, the Common Stock will be deregistered under the
Exchange Act and will no longer be publicly traded on The Nasdaq SmallCap
Market.
 
APPRAISAL RIGHTS
 
     Under the DGCL, any stockholder that does not wish to accept $3.50 per
share for his, her or its shares of Common Stock as provided in the Merger
Agreement has the right to dissent from the Merger and to seek an appraisal of,
and to be paid the fair value (exclusive of any element of value arising from
the accomplishment or expectation of the Merger) for the shares of Common Stock,
provided that such stockholder complies with the provisions of Section 262 of
the DGCL.
 
     Holders of record of Common Stock who do not vote in favor of the Merger
Agreement (including those who abstain with respect to the Merger Proposal and
those who do not provide specific voting instructions to brokers who hold their
shares of Common Stock in "street name") and who otherwise comply with the
applicable statutory procedures will be entitled to appraisal rights under
Section 262 of the DGCL. A person having a beneficial interest in shares of
Common Stock held of record in the name of another person, such as a broker or
nominee, must act promptly to cause the record holder to follow the steps
summarized below properly and in a timely manner to perfect appraisal rights.
 
     THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL
TEXT OF SECTION 262 OF THE DGCL THAT IS REPRINTED IN ITS ENTIRETY AS ANNEX IV.
ALL REFERENCES IN SECTION 262 OF THE DGCL AND IN THIS SUMMARY TO A "STOCKHOLDER"
OR "HOLDER" ARE TO THE RECORD HOLDER OF THE SHARES OF COMMON STOCK AS TO WHICH
APPRAISAL RIGHTS ARE ASSERTED.
 
     Under Section 262 of the DGCL, holders of shares of Common Stock
("Appraisal Shares") who follow the procedures set forth in Section 262 of the
DGCL will be entitled to have their Appraisal Shares appraised by the Delaware
Chancery Court and to receive payment in cash of the "fair value" of such
Appraisal Shares, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, as determined by such court.
 
     Under Section 262 of the DGCL, where a proposed merger is to be submitted
for approval at a meeting of stockholders, the corporation, not less than 20
days prior to the meeting, must notify each of its stockholders who was a
stockholder on the record date for such meeting with respect to shares for which
appraisal rights are available, that appraisal rights are so available, and must
include in such notice a copy of Section 262 of the DGCL.
 
     This Proxy Statement constitutes such notice to the holders of Appraisal
Shares and the applicable statutory provisions of the DGCL are attached to this
Proxy Statement as Annex IV. Any stockholder who wishes to exercise such
appraisal rights or that wishes to preserve his, her or its right to do so
should review the following discussion and Annex IV carefully, because failure
to timely and properly comply with the procedures therein specified will result
in the loss of appraisal rights under the DGCL.
 
     A holder of Appraisal Shares wishing to exercise such holder's appraisal
rights (i) must not vote in favor of the Merger Agreement or consent thereto in
writing (including by returning a signed Proxy without indicating any voting
instructions as to the Merger Proposal) and (ii) must deliver to the Company
prior to the vote on the Merger Agreement at the Special Meeting, a written
demand for appraisal of such holder's Appraisal Shares. This written demand for
appraisal must be in addition to and separate from any proxy or vote abstaining
from or against the Merger. This demand must reasonably inform the Company of
the identity of the stockholder and of the stockholder's intent thereby to
demand appraisal of his, her or its shares. A holder of Appraisal Shares wishing
to exercise such holder's appraisal rights must be the record holder of such
Appraisal Shares on the date the written demand for appraisal is made and must
continue to hold such Appraisal Shares until the consummation of the Merger.
Accordingly, a holder of Appraisal Shares who is the record holder of Appraisal
Shares on the date the written demand for appraisal is made, but who thereafter
 
                                       27
<PAGE>   35
 
transfers such Appraisal Shares prior to consummation of the Merger, will lose
any right to appraisal in respect of such Appraisal Shares.
 
     Only a holder of record of Appraisal Shares is entitled to assert appraisal
rights for the Appraisal Shares registered in that holder's name. A demand for
appraisal should be executed by or on behalf of the holder of record, fully and
correctly, as such holder's name appears on such holder's stock certificates. If
the Appraisal Shares are owned of record in a fiduciary capacity, such as by a
trustee, guardian or custodian, execution of the demand should be made in that
capacity, and if the Appraisal Shares are owned of record by more than one owner
as in a joint tenancy or tenancy in common, the demand should be executed by or
on behalf of all joint owners. An authorized agent, including one or more joint
owners, may execute a demand for appraisal on behalf of a holder of record;
however, the agent must identify the record owner or owners and expressly
disclose the fact that, in executing the demand, the agent is agent for such
owner or officers. A record holder such as a broker who holds Appraisal Shares
as nominee for several beneficial owners may exercise appraisal rights with
respect to the Appraisal Shares held for one or more beneficial owners while not
exercising such rights with respect to the Appraisal Shares held for other
beneficial owners; in such case, the written demand should set forth the number
of Appraisal Shares as to which appraisal is sought. When no number of Appraisal
Shares is expressly mentioned, the demand will be presumed to cover all
Appraisal Shares in brokerage accounts or other nominee forms and those who wish
to exercise Appraisal Rights under Section 262 of the DGCL are urged to consult
with their brokers to determine the appropriate procedures for the making of a
demand for appraisal by such a nominee.
 
     ALL WRITTEN DEMANDS FOR APPRAISAL SHOULD BE SENT OR DELIVERED TO PURETEC
CORPORATION AT 65 RAILROAD AVENUE, RIDGEFIELD, NEW JERSEY 07657, ATTENTION:
SECRETARY.
 
     Within ten days after the consummation of the Merger, the Company will
notify each stockholder that has properly asserted appraisal rights under
Section 262 of the DGCL and has not voted in favor of the Merger Agreement of
the date the Merger became effective.
 
     Within 120 days after the consummation of the Merger, but not thereafter,
the Company or any stockholder who has complied with the statutory requirements
summarized above may file a petition in the Delaware Chancery Court demanding a
determination of the fair value of the Appraisal Shares that are entitled to
appraisal rights. The Company is under no obligation to and has no present
intention to file a petition with respect to the appraisal of the fair value of
the Appraisal Shares that are entitled to appraisal rights. Accordingly, it will
be the obligation of stockholders wishing to assert appraisal rights to initiate
all necessary action to perfect their appraisal rights within the time
prescribed in Section 262 of the DGCL.
 
     Within 120 days after the consummation of the Merger, any stockholder that
has complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from the Company a statement setting
forth the aggregate number of Appraisal Shares not voted in favor of adoption of
the Merger Agreement and with respect to which demands for appraisal have been
received and the aggregate number of holders of such Appraisal Shares. Such
statements must be mailed within 10 days after a written request therefor has
been received by the Company, or within 10 days after expiration of the period
for delivery of demands for appraisal under Section 262 of the DGCL, whichever
is later.
 
     If a petition for an appraisal is filed on a timely basis, after a hearing
on such petition, of which the Register in Chancery (if so ordered by the
Delaware Chancery Court) shall give notice to stockholders, the Delaware
Chancery Court will determine the stockholders entitled to appraisal rights and
will appraise the "fair value" of their Appraisal Shares, exclusive of any
element of value arising from the accomplishment or expectation of the Merger,
together with a fair rate of interest, if any, to be paid upon the amount
determined to be the fair value. Stockholders considering seeking appraisal
should be aware that the fair value of their Appraisal Shares as determined
under Section 262 of the DGCL could be more than, the same as or less than the
value of the consideration they would receive pursuant to the Merger Agreement
if they did not seek appraisal of their Appraisal Shares and that investment
banking opinions as to fairness from a financial point of view are not
necessarily opinions as to fair value under Section 262 of the DGCL. The
Delaware Supreme Court has stated, however, that "proof of value by any
techniques or methods that are generally considered
 
                                       28
<PAGE>   36
 
acceptable in the financial community and otherwise admissible in court" should
be considered in the appraisal proceedings.
 
     The Delaware Chancery Court will determine the amount of interest, if any,
to be paid upon the amounts to be received by stockholders whose Appraisal
Shares have been appraised. The costs of the action may be determined by the
Delaware Chancery Court and taxed upon the parties as the Delaware Chancery
Court deems equitable. The Delaware Chancery Court may also order that all or a
portion of the expenses incurred by any stockholder in connection with an
appraisal, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts utilized in the appraisal proceeding, be charged
pro rata against the value of all of the Appraisal Shares entitled to appraisal.
 
     Any holder of Appraisal Shares that has duly demanded an appraisal in
compliance with Section 262 of the DGCL will not, after the consummation of the
Merger, be entitled to vote the Appraisal Shares subject to such demand for any
purpose or be entitled to the payment of dividends or other distributions on
those Appraisal Shares (except dividends or other distributions payable to
holders of record of Appraisal Shares as of a record date prior to the
consummation of the Merger).
 
     If any stockholder that properly demands appraisal of his, her or its
Appraisal Shares under Section 262 of the DGCL fails to perfect, or effectively
withdraws or loses, his, her or its right to appraisal, as provided in Section
262 of the DGCL, the Appraisal Shares of such stockholder will be converted into
the right to receive the consideration receivable with respect to such Appraisal
Shares in accordance with the Merger Agreement. A stockholder will fail to
perfect, or effectively lose or withdraw, his, her or its right to appraisal if,
among other things, no petition for appraisal is filed within 120 days after the
consummation of the Merger, or if such stockholder delivers to the Company a
written withdrawal of his, her or its demand for appraisal. Any such attempt to
withdraw an appraisal demand more than 60 days after the consummation of the
Merger will require the written approval of the Company.
 
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR
PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH
EVENT A STOCKHOLDER WILL BE ENTITLED TO RECEIVE THE CONSIDERATION RECEIVABLE
WITH RESPECT TO HIS, HER OR ITS APPRAISAL SHARES IN ACCORDANCE WITH THE MERGER
AGREEMENT).

                              THE MERGER AGREEMENT
 
     The following is a brief summary of certain material provisions of the
Merger Agreement that is attached as Annex I to this Proxy Statement and
incorporated herein by reference. Such summary does not purport to be complete
and is qualified in its entirety by reference to the Merger Agreement. All
capitalized terms used herein and not defined are used as defined in the Merger
Agreement. Stockholders are urged to review the Merger Agreement carefully and
in its entirety.
 
THE MERGER
 
     In General.  The Merger Agreement provides that, following the approval and
adoption of the Merger Agreement by the stockholders of the Company and the
satisfaction or waiver of the other conditions to the Merger, Sub will be merged
with and into the Company, the separate existence of Sub will cease and the
Company will be the Surviving Corporation. The Merger Agreement also provides
that Tekni-Plex may elect to merge the Company with and into Sub, with Sub
remaining as the Surviving Corporation. Following the Merger, the Surviving
Corporation will be a wholly owned subsidiary of Tekni-Plex. As a result of the
Merger, all the rights, privileges, powers and franchises of the Company and Sub
will vest in the Surviving Corporation and all restrictions, liabilities and
duties of the Company and Sub will become the restrictions, liabilities and
duties of the Surviving Corporation.
 
     Effective Time.  The Merger Agreement provides that, at the earliest time
following the satisfaction or, to the extent permitted under the Merger
Agreement, waiver of all conditions to the Merger, the Company and Sub will file
a certificate of merger with the Secretary of State of the State of Delaware and
make all other filings or recordings required by the DGCL in connection with the
Merger, and the Merger will become effective upon such filing or at such later
time as is specified in such certificate of merger. If the stockholders of the
Company approve the Merger Proposal, the Effective Time is expected to occur as
soon as practicable following the Special Meeting but in no event later than
March 31, 1998.
 
     Conversion of Securities.  At the Effective Time, (i) each outstanding
share of Common Stock held by the Company as treasury stock or owned by
Tekni-Plex or any subsidiary of Tekni-Plex immediately prior to the Effective
Time shall be canceled and no payment shall be made with respect thereto; (ii)
each share of common stock of Sub outstanding immediately prior to the Effective
Time will be converted into and become one share of common stock of the
Surviving Corporation (see "The Merger -- Certain Consequences of the Merger");
and (iii) each share of Common Stock outstanding immediately prior to the
Effective Time shall, except as otherwise provided in (a) above or as provided
in the following paragraph, be converted into the right to receive the Merger
Consideration.
 
     Shares of Common Stock outstanding immediately prior to the Effective Time
and held by a holder who has not voted in favor of the Merger or consented
thereto in writing and who has delivered a written demand for appraisal of such
shares in accordance with Section 262 of the DGCL shall not be converted into a
right to receive the Merger Consideration, unless such holder fails to perfect,
withdraws or otherwise loses his, her or its right to appraisal. If after the
Effective Time such holder fails to perfect, withdraws or loses his, her or its
right to appraisal, such shares shall be treated as if they had been converted
as of the Effective Time into a right to receive the Merger Consideration.
 
     Exchange of Certificates.  As soon as practicable after the Effective Time,
a paying agent designated by Tekni-Plex (the "Exchange Agent") will mail to each
holder of shares of Common Stock a letter of transmittal for use in effecting
the surrender of the certificates representing shares of Common Stock (the
"Certificates") in exchange for the Merger Consideration. The letter of
transmittal shall specify that the delivery shall be effected and risk of loss
and title shall pass only upon proper delivery of the Certificates representing
the Common Stock to the Exchange Agent. Upon surrender of a Certificate to the
Exchange Agent, together with a duly executed letter of transmittal and any
other required documents, the holder of such shares will be entitled to receive
the Merger Consideration and until so surrendered, each such Certificate shall,
after the Effective Time, represent for all purposes, only the right to receive
the Merger Consideration. No interest will be paid or accrued on the Merger
Consideration. After the Effective Time, holders of Certificates will have no
right to vote or to receive any dividends or other distributions with respect
 
                                       30
<PAGE>   38
 
to any shares of Common Stock, other than any distributions payable to holders
of record as of a date prior to the Effective Time, and shall have no other
rights other than as provided in the Merger Agreement or by applicable law.
After the Effective Time, there shall be no further registration of transfers of
shares of Common Stock. If, after the Effective Time, certificates representing
shares of Common Stock are presented to the Surviving Corporation, they shall be
canceled and exchanged for the Merger Consideration provided for, and in
accordance with the procedures set forth, above.
 
     If any portion of the Merger Consideration is to be paid to a Person other
than the registered holder of the shares of Common Stock represented by the
Certificate or Certificates surrendered in exchange therefor, it shall be a
condition to such payment that the Certificate or Certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such payment shall: (i) pay to the Exchange Agent any
transfer or other taxes required as a result of such payment to a Person other
than the registered holder of such Common Stock; or (ii) establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
payable.
 
     Any portion of the Merger Consideration made available to the Exchange
Agent that remains unclaimed by the holders of shares of Common Stock six months
after the Effective Time shall be returned to Tekni-Plex, upon demand, and any
such holder who has not exchanged his, her or its shares of Common Stock for the
Merger Consideration prior to that time shall thereafter look only to Tekni-Plex
for payment of the Merger Consideration in respect of such shares.
Notwithstanding the foregoing, Tekni-Plex shall not be liable to any holder of
shares of Common Stock for any amount paid to a public official pursuant to
applicable abandoned property laws. Any amounts remaining unclaimed by holders
of Common Stock two years after the Effective Time (or such earlier date
immediately prior to such time as such amounts would otherwise escheat to or
become property of any governmental entity) shall, to the extent permitted by
applicable law, become the property of Tekni-Plex free and clear of any claims
or interest of any Person previously entitled thereto.
 
     Any portion of the Merger Consideration made available to the Exchange
Agent to pay for Common Stock for which appraisal rights have been perfected
shall be returned to Tekni-Plex upon demand. The Exchange Agent will be entitled
to deduct and withhold from the Merger Consideration such amounts as may be
required under the Code. Such withheld amounts shall be treated as having been
paid to the holder of the Certificates in respect of which such deduction and
withholding was made by the Exchange Agent.
 
     STOCKHOLDERS OF THE COMPANY SHOULD NOT FORWARD THEIR STOCK CERTIFICATES TO
THE EXCHANGE AGENT WITHOUT A LETTER OF TRANSMITTAL AND SHOULD NOT RETURN THEIR
STOCK CERTIFICATES WITH THE ENCLOSED PROXY.
 
     Options.  At the Effective Time, each holder of an outstanding Option,
whether or not then vested or exercisable, granted under the 1995 Disinterested
Directors Stock Option Plan of the Company or the 1995 Stock Option Plan of the
Company (together, the "Option Plans") shall be paid by the Company, promptly
upon surrender of such Option, net of applicable withholding, an amount
determined by multiplying (i) the excess, if any, of the Merger Consideration
over the applicable exercise price per share of Common Stock subject to such
Option and (ii) the number of shares of Common Stock such holder could have
purchased (assuming full vesting of all Options) had such holder exercised such
Option in full immediately prior to the Effective Time. In addition, promptly
following the Effective Time, the Company shall notify all holders of
outstanding options or warrants to purchase Common Stock, other than those
referred to in the preceding sentence, that such holders are entitled to receive
the Merger Consideration upon surrender of such options or warrants and payment
to the Company by the holders thereof of the applicable exercise price (and in
the case of Options referred to in the preceding sentence, of such right to
receive the payment described in the preceding sentence in lieu of exercising
such Options).
 
     Debt Tender Offer.  The Company agreed to cause PS&T to promptly commence
the Debt Tender Offer for any and all of the PS&T Notes, in accordance with
applicable law and pursuant to documentation reasonably satisfactory to
Tekni-Plex, at a cash price to be specified by Tekni-Plex or at such other price
as Tekni-Plex may specify from time to time thereafter. The Company has also
agreed to cause PS&T to purchase the PS&T Notes tendered pursuant to the Debt
Tender Offer at the Effective Time. The Debt Tender Offer and consent
solicitation relating to the Proposed Amendments (as defined below) are expected
 
                                       31
<PAGE>   39
 
to be commenced by PS&T contemporaneous with or shortly following the mailing of
this Proxy Statement. The Company will disclose the pricing information relating
to the Debt Tender Offer via press release and the filing with the Commission of
a Current Report on Form 8-K under the Exchange Act as soon as practicable after
such pricing information is available. The Debt Tender Offer is subject to the
conditions that (i) there shall be validly tendered and not withdrawn in
accordance with the terms of the Debt Tender Offer prior to the expiration date
of the Debt Tender Offer, PS&T Notes in an aggregate principal amount
representing at least a majority in principal amount of the PS&T Notes; (ii) the
holders of at least a majority in principal amount of the PS&T Notes shall have
consented prior to the Effective Time to amend the PS&T Indenture and the
Collateral Documents (as defined below), to delete such covenants, events of
default and other provisions of the PS&T Indenture and the Collateral Documents
as Tekni-Plex has specified and to make such other amendments to the PS&T
Indenture and the Collateral Documents as Tekni-Plex has required (the "Proposed
Amendments"); and (iii) Tekni-Plex shall have consummated or, simultaneously
with the consummation of the Debt Tender Offer, shall consummate the Merger.
 
     The Proposed Amendments are expected to effectively eliminate from the PS&T
Indenture all of the covenants of the Company contained therein (except for
those covenants relating to (a) the Company's obligations to pay principal and
interest, (b) certain change of control and asset sale events and (c) Collateral
(as defined below)), including those covenants relating to (i) the filing of
Commission reports; (ii) the delivery of compliance certificates; (iii) the
payment of taxes; (iv) the limitation on restricted payments; (v) the limitation
on dividends and other payment restrictions affecting restricted subsidiaries;
(vi) the limitation on indebtedness; (vii) certain restrictions on asset sales;
(viii) the limitation on sale and leaseback transactions; (ix) the limitation on
transactions with affiliates; (x) the limitation on liens; (xi) corporate
existence; (xii) the Company's ability to liquidate; (xiii) the maintenance of
properties; (xiv) the maintenance of insurance; (xv) certain payments for
consent to amendments to the PS&T Indenture; and (xvi) certain payments to
affiliates. In addition, the Proposed Amendments are expected to eliminate the
provisions of the PS&T Indenture that govern and restrict the Company's ability
to merge or sell assets. Certain events of default, including the covenant
default, cross default and judgment default provisions will also be eliminated.
 
     The Proposed Amendments are also expected to effectively eliminate from the
Collateral Documents (which include the Security Agreement, the Pledge
Agreement, the Patent Security Agreement and the Trademark Security Agreement
each dated as of November 8, 1993 and each between PS&T and the Trustee under
the PS&T Indenture) all of the covenants of PS&T contained therein (except for
those covenants relating to cooperation with the Trustee under the PS&T
Indenture with respect to the preservation of liens on the collateral securing
the PS&T Notes (the "Collateral")). The covenants and other provisions to be
deleted from the Collateral Documents include but are not limited to covenants
and other provisions relating to (i) limitations on liens, (ii) the location of
the Collateral, (iii) the disposition of the Collateral, (iv) restrictions on
sales of the Collateral, (v) the proceeds from dispositions of the Collateral,
(vi) the maintenance of insurance, (vii) the payment of taxes, (viii) the
maintenance of the Collateral, (ix) the prohibition on mergers of PS&T, (x) the
voting of, and receipt of dividends on, pledged shares of stock, (xi) the
licensing of patents and trademarks, and (xii) the maintenance and defense of
patents and trademarks.
 
     In addition as a part of such consent solicitation, the Company expects to
seek a waiver of all prior existing events of default with respect to the PS&T
Notes and of PS&T's obligation to make an offer to purchase the PS&T Notes in
the event the Merger or the restructuring of the Company following the Merger
are deemed to be a change of control or an asset sale, as defined in the PS&T
Indenture.
 
     Upstream Guarantees.  Effective as of the Effective Time, the Company has
agreed that it shall and shall cause each of its domestic subsidiaries to
guarantee (i) the Tekni-Plex Notes, to the extent required by the Tekni-Plex
Indenture, and (ii) any indebtedness of Tekni-Plex issued to finance the
transactions contemplated by the Merger Agreement.
 
     PS&T Minority Interest.  The Company has also agreed that it shall
eliminate the PS&T Minority Interest, either pursuant to an offer to purchase
such minority shares or pursuant to sec.253 of the DGCL, at a
 
                                       32
<PAGE>   40
 
price of $7.00 per share of common stock of PS&T, at any time prior to but no
later than immediately prior to the consummation of the Merger.
 
     Intercompany Loans.  Simultaneously with the consummation of the Merger,
Tekni-Plex has agreed to loan to each of the Company and its Subsidiaries funds
sufficient to enable each of the Company and its Subsidiaries to finance the
Related Transactions. The obligation of the Company and its Subsidiaries under
the Merger Agreement to consummate the Related Transactions are contingent upon
receipt of such loans from Tekni-Plex in amounts sufficient to consummate the
Related Transactions.
 
     Other Subsidiary Debt.  Prior to or simultaneously with the consummation of
the Merger, the Company has agreed to cause each of its Subsidiaries to repay
and retire such of its outstanding debt (other than any PS&T Notes not tendered
in the Debt Tender Offer) as Tekni-Plex may require.

action that would make any representation and warranty of the Company under the
Merger Agreement that is qualified as to materiality inaccurate in any respect
or any representation and warranty of the Company under the Merger Agreement
that is not qualified as to materiality inaccurate in any material respect, in
each case at, or as of any time prior to, the Effective Time; or (ii) omit or
agree or commit to omit to take any action necessary to prevent any such
representation or warranty from being inaccurate in any respect (or, with
respect to representations and warranties of the Company under the Merger

     The Company believes that it is currently in compliance with all of its
covenants under the Merger Agreement, including, without limitation, those set
forth above in subparagraphs (iv), (v) and (vi) regarding the Company's capital
expenditures, inventories and accounts payable, respectively.
 
     No Solicitation.  Under the Merger Agreement, the Company and the
Subsidiaries have agreed that until the termination of the Merger Agreement, the
Company and the Subsidiaries and the officers, directors, employees or other
agents of the Company and the Subsidiaries will not, directly or indirectly,
take any action to solicit, initiate or take any action knowingly to facilitate
the submission of any Acquisition Proposal or, subject to the fiduciary duties
of the Board of Directors under applicable law as advised by counsel to the
Company, engage in negotiations with, or disclose any nonpublic information
relating to the Company or any Subsidiary or afford access to the properties,
books or records of the Company or any Subsidiary to, any Person, except to
customers and suppliers of the Company and the Subsidiaries in the ordinary
course of business. The Company has also agreed to promptly notify Tekni-Plex
after receipt of any Acquisition Proposal or any indication that any Person is
considering making an Acquisition Proposal or any request for nonpublic
information relating to the Company or any Subsidiary or for access to the
properties, books or records of the Company or any Subsidiary by any Person that
may be considering making, or has made, an Acquisition Proposal and to keep
Tekni-Plex fully informed of the status and, subject to the fiduciary duties of
the Board of Directors of the Company under the DGCL, details of any such
Acquisition Proposal, indication or request. For purposes of the foregoing,
"Acquisition Proposal" means any offer or proposal for, or any indication of
interest in, a merger or other business combination involving the Company or any
Subsidiary or the acquisition of any equity interest in, or a substantial
portion of the assets of, the Company or any Subsidiary, other than the
transactions contemplated by the Merger Agreement. Notwithstanding the
foregoing, pursuant to the Merger Agreement, if the Board of Directors receives
an Acquisition Proposal that it determines in good faith will provide greater
value to the Company and its stockholders than the transactions contemplated
under the Merger Agreement (a "Superior Proposal"), the Board of Directors may,
prior to the receipt of approval of the Merger from the stockholders of the
Company, withdraw or modify its approval or recommendation of the Merger and the
Merger Agreement, approve or recommend a Superior Proposal or terminate the
Merger in accordance with the terms of the Merger Agreement but in each case,
only at a time that is at least five business days after TekniPlex's receipt of
written notice advising Tekni-Plex that the Board of Directors has received a
Superior Proposal, specifying the material terms and conditions of such Superior
Proposal and the names of the person or persons making such Superior Proposal.
Within the
 
                                       35
<PAGE>   43
 
five-business-day period referred to above, the Merger Agreement provides that
Tekni-Plex may propose an improved transaction to the Board of Directors.
 
     Cooperative Efforts.  The Company agrees, and agrees to cause each of the
Subsidiaries, to cooperate with and use its best efforts to assist Tekni-Plex in
connection with the New Bond Placement, including but not limited to,
participating in marketing efforts, participating in the preparation of
disclosure relating to the Company and the Subsidiaries to be included in any
related offering documents, and participating in the preparation of pro forma
financial information relating to Tekni-Plex and the Company on a combined
basis. The Company also shall, and shall cause PS&T to, use its best efforts to
consummate the Debt Tender Offer on a timely basis. The Company shall keep
TekniPlex apprised on a regular and timely basis of all significant developments
relating to the Debt Tender Offer and shall consult with Tekni-Plex prior to
taking any significant actions or making any significant decisions in connection
therewith.
 
     Loans to Affiliated Persons.  The Company shall cause all loans extended by
the Company or any of the Subsidiaries to the officers and directors of the
Company and the Subsidiaries on the date of the Merger Agreement to be repaid in
full, whether or not then due, prior to or concurrently with the consummation of
the Merger and shall use its best efforts to cause all loans extended by the
Company or any of the Subsidiaries to former officers and directors, current
employees (except for loans to facilitate relocations of current employees) and
former employees and associates of the Company to be repaid in full, whether or
not then due, prior to or concurrently with the consummation of the Merger.
Tekni-Plex consents to the discharge of such loans dollar for dollar through the
surrender and cancellation without payment of the same principal amount of 7%
Subordinated Notes of the Company described in the Merger Agreement.
 
     Severance Arrangements.  The Company agreed to adopt, prior to the
Effective Time, a severance payment plan having the terms contemplated by the
Merger Agreement pursuant to documentation satisfactory to each of Tekni-Plex
and the Company, in lieu of and replacing any existing severance payment plan
covering any current or future employees of the Company and the Subsidiaries.
See "The Merger -- Interests of Certain Persons in the Merger."
 
     Convertible Note.  As discussed under "The Merger -- Financing the Merger,"
concurrently with the execution of the Merger Agreement, the Company issued the
Convertible Note to Tekni-Plex in return for a $5 million loan which has
assisted the Company and PS&T in meeting expected cash requirements in the
period prior to the completion of the Merger. Immediately upon receipt of the $5
million loan, as agreed, the Company made $4.6 million available to PS&T, which
used such funds to pay down outstanding debt under the revolving credit facility
described in the Amended and Restated Senior Loan Agreement dated as of November
8, 1993, as amended, among PS&T, the lenders named therein and General Electric
Capital Corporation, as agent (the "PS&T Credit Agreement"). PS&T further agreed
to make future borrowings under the PS&T Credit Agreement only after reasonable
consultation with Tekni-Plex, in the event that immediately following such
borrowing, less than $4.6 million of undrawn capacity for borrowing would remain
available to PS&T.
 
     Other Covenants of the Company.  The Merger Agreement also contains
customary covenants of the Company applicable to consummating the Merger. These
include covenants relating to the preparation of this Proxy Statement and
holding the Special Meeting, access to information, and notification of certain
events.
 
     Obligations of Sub.  Tekni-Plex and Sub have agreed that Tekni-Plex will
take all action necessary to cause Sub to perform its obligations under the
Merger Agreement and to consummate the Merger on the terms and conditions set
forth in the Merger Agreement.
 
     Director and Officer Liability.  Each of the Surviving Corporation and PS&T
will, pursuant to provisions in their respective certificates of incorporation
and by-laws, indemnify and hold harmless the present and former officers and
directors of the Company and PS&T, respectively, in respect of acts or omissions
occurring while such persons are officers and directors to the same extent as is
provided under each of the Company's and PS&T's, respectively, certificate of
incorporation and bylaws in effect on the date of the Merger Agreement, and
Tekni-Plex will not amend, repeal or modify such provisions in any manner that
would
 
                                       36
<PAGE>   44
 
adversely affect the rights thereunder of such persons; provided that such
indemnification shall be subject to any limitation imposed from time to time
under applicable law.
 
     For four years after the Effective Time, Tekni-Plex will cause each of the
Surviving Corporation and PS&T, respectively, to use its best efforts to provide
officers' and directors' liability insurance in respect of acts or omissions
occurring prior to the Effective Time covering each such person currently
covered by the Company's and PS&T's officers' and directors' liability insurance
policy on terms with respect to coverage and amount no less favorable in the
aggregate than those of the applicable policy in effect on the date of the
Merger Agreement, provided that in satisfying such obligation, Tekni-Plex shall
not be obligated to cause the Surviving Corporation or PS&T to purchase an
amount of such insurance in excess of the amount that can be purchased for
premiums of 120% of the amount per annum the Company or PS&T paid in its full
fiscal year.
 
     Commitment Letters and Financing Agreements.  Tekni-Plex has agreed that it
will not amend or otherwise modify the Commitment Letters in any material
respect adverse to Tekni-Plex or the Company, or grant any waivers with respect
thereto, without the prior consent of the Company, will provide the Company with
drafts of the Financing Agreements as soon as they are provided by the Lender or
its counsel, will use its best efforts to obtain the Financing and will inform
the Company in writing within five business days of its becoming aware of any
facts or circumstances that might reasonably be expected to result in the
Commitment Letters being terminated or any of the conditions therein not being
satisfied, or the amount of the Financing to be provided pursuant to the
Commitment Letters or the Financing Agreements not being sufficient to complete
all of the transactions contemplated by the Merger Agreement.
 
     Repurchase of Tekni-Plex Notes.  In the event that the consummation of the
Merger or the drawing of funds under the Financing Agreements would be
reasonably likely to violate or cause an event of default under the Tekni-Plex
Indenture, Tekni-Plex shall, at the earliest practicable time following
Tekni-Plex's obtaining knowledge thereof, notify the Company of such fact and
commence a combined consent solicitation and offer to purchase any and all of
the Tekni-Plex Notes issued thereunder. As of the date of this Proxy Statement,
Tekni-Plex has not provided the Company with such notice. The documentation for
such offer and consent solicitation, including without limitation the conditions
thereto, shall be reasonably satisfactory to the Company, and Tekni-Plex shall
take all actions reasonably necessary in connection therewith to obtain the
consent of holders of the principal amount of such Notes that would be
sufficient to amend or eliminate those provisions of the Tekni-Plex Indenture
that would be contravened by the consummation of the Merger.
 
     Mutual Covenants.  The Merger Agreement also contains mutual covenants of
the Company, Tekni-Plex and Sub applicable to consummating the Merger. These
covenants include, among other things, covenants relating to cooperation in
connection with the preparation of certain documents, making governmental
filings, obtaining consents and approvals, and procedures with respect to public
announcements.

     consummated by March 31, 1998;
 
          (iii) either the Company or Tekni-Plex, if there shall be any law or
     regulation that makes consummation of the Merger illegal or otherwise

     judgment, injunction, order or decree shall become final and nonappealable;
 
          (iv) Tekni-Plex, if any Person, entity or "group" (as defined in

     beneficial ownership of 50% or more of the outstanding Common Stock;
 
          (v) Tekni-Plex, if prior to the Effective Time, the Board of Directors

                                       39
<PAGE>   47
 
     any Person, entity or "group" (as defined in Section 13(d)(3) of the
     Exchange Act) other than Tekni-Plex or Sub shall have acquired or proposed
     to acquire beneficial ownership of more than 20% of any class or series of
     capital stock of the Company (including the Common Stock), through the
     acquisition of stock, the formation of a group or otherwise, or shall have
     been granted any option, right or warrant, conditional or otherwise, to
     acquire beneficial ownership of more than 20% of any class or series of
     capital stock of the Company (including the Common Stock);
 
          (vii) either Tekni-Plex or the Company, if the Special Meeting shall
     have been held and the stockholders of the Company shall have failed to
     approve and adopt the Merger Agreement and the Merger at such meeting;
 
          (viii) either Tekni-Plex or the Company, if Tekni-Plex shall have
     received any communication from the Department of Justice or the FTC (each
     an "HSR Authority") (which communication shall be confirmed to the other
     parties by the HSR Authority) that causes such party to reasonably believe
     that any HSR Authority has authorized the institution of litigation
     challenging the transactions contemplated by the Merger Agreement under the
     United States antirust laws, which litigation will include a motion seeking
     an order or injunction prohibiting the consummation of any of the
     transactions contemplated by the Merger Agreement; and
 
          (ix) the Company, if (a) the Board of Directors concludes in good
     faith, based on written advice from outside counsel, that, in order to
     prevent the Board of Directors from breaching its fiduciary duties to the
     stockholders of the Company, it must withdraw or materially modify its
     approval or recommendation of the Merger or the Merger Agreement, and it
     withdraws or materially modifies such approval or recommendation, (b) the
     Company complies with its obligations described under " -- Certain
     Covenants -- No Solicitation" and (c) the Company pays all amounts due to
     Buyer pursuant to the Merger Agreement in advance of such termination.
 
     Effect of Termination.  If the Merger Agreement is terminated in accordance
with its terms, it shall become void and of no effect with no liability on the
part of any party thereto, except that the agreements contained in the Merger
Agreement with respect to termination costs and expenses shall survive the
termination thereof.
 
FEES AND EXPENSES
 
     Except as described below, all costs and expenses incurred in connection
with the Merger Agreement will be paid by the party incurring such costs or
expenses.
 
     The Company and PS&T jointly and severally agree to pay Tekni-Plex, in
immediately available funds, promptly, but in no event later than two business
days, after (or, in the case of a termination described in clause (ix) under
" -- Termination of the Merger Agreement -- Termination," prior to) a
termination of the Merger Agreement described in clauses (iv), (v) or (ix) under
" -- Termination of the Merger Agreement -- Termination," (x) a fee of $10
million and (y) reasonable and documented costs and expenses, not to exceed $5
million in the aggregate, incurred by Tekni-Plex and its subsidiaries and their
representatives in connection with the transactions contemplated by the Merger
Agreement, which costs and expenses shall include, without limitation, fees and
expenses payable by the Company to the Lender pursuant to the Commitment
Letters, the costs and expenses in connection with the New Bond Placement, and
fees and expenses of counsel and costs and expenses of the due diligence
investigations of the Company and the Subsidiaries; provided, that payment of
any amounts by the Company or PS&T as described above shall constitute a
complete accord and satisfaction of all claims pursuant to the Merger Agreement
that either Tekni-Plex or Sub may have against the Company or PS&T and all
claims that the Company or PS&T may have against Tekni-Plex or Sub, arising out
of such termination and relating to the Merger Agreement (it being understood
that the foregoing shall not affect in any respect the Company's obligations
under the Convertible Note or the Stockholder Voting Agreement).
 
     In the event the Merger Agreement is terminated as a result of Tekni-Plex
having breached its obligations thereunder or as a result of Tekni-Plex's
failure to obtain the Financing for any reason, in whole or in part, not related
to the Company's or the Subsidiaries' actions and, in either case, all of the
other conditions set forth in the Merger Agreement to the obligations of
Tekni-Plex and Sub shall have been satisfied, Tekni-
 
                                       40
<PAGE>   48
 
Plex shall pay the out-of-pocket costs and expenses incurred by the Company and
the Subsidiaries solely in connection with the New Bond Placement.
 
AMENDMENT; WAIVER
 
     Any provision of the Merger Agreement may be amended or waived prior to the
Effective Time if, and only if, such amendment or waiver is in writing and
signed, in the case of an amendment, by the Company, Tekni-Plex and Sub or in
the case of a waiver, by each party against whom the waiver is to be effective;
provided that after the adoption of the Merger Agreement by the stockholders of
the Company, there shall be made no amendment or waiver that by law requires
further approval by such stockholders without the further approval of such
stockholders. In addition, no failure or delay by any party in exercising any
right, power or privilege under the Merger Agreement shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies provided under the Merger Agreement shall be cumulative
and not exclusive of any rights or remedies provided by law.

                        THE STOCKHOLDER VOTING AGREEMENT
 
     The following summarizes the material provisions of the Stockholder Voting
Agreement, a copy of which appears as Annex II to this Proxy Statement and is
incorporated herein by reference. This summary is qualified in its entirety by
reference to the Stockholder Voting Agreement.
 
VOTING
 
     Each Affiliated Stockholder has agreed to vote all Subject Shares that such
Affiliated Stockholder is entitled to vote in favor of the approval and adoption
of all Merger Related Actions at any meeting of the stockholders of the Company,
and at any adjournment thereof, at which such Merger Related Actions (or any
amended version thereof), or such other actions, are submitted for the
consideration and vote of the stockholders of the Company. Each Affiliated
Stockholder hereby has agreed that, until the earlier of (x) the consummation of
the Merger and (y) the termination of the Merger Agreement (the "Voting Expiry
Date") it will not vote any Subject Shares in favor of the approval of any (i)
Acquisition Proposal, (ii) reorganization, recapitalization, liquidation or
winding up of the Company or any other extraordinary transaction involving the
Company, (iii) corporate action the consummation of which would frustrate the
purposes, or prevent or delay the consummation, of the transactions contemplated
by the Merger Agreement or (iv) other matter relating to, or in connection with,
any of the foregoing matters.
 
     Under the Stockholder Voting Agreement the Affiliated Stockholders have
made no agreement or understanding in their capacities as directors or officers
of the Company. Each Affiliated Stockholder has signed solely in his capacity as
a recordholder and/or beneficial owner of the Subject Shares and nothing in the
Stockholder Voting Agreement shall limit or affect any actions taken in such
Affiliated Stockholder's capacity as an officer or director of the Company.
 
     In addition, under the Stockholder Voting Agreement, each Affiliated
Stockholder revoked any and all previous proxies granted with respect to the
Subject Shares and granted by a proxy appointing Tekni-Plex as such Affiliated
Stockholder's attorney-in-fact and proxy, with full power of substitution, for
and in such Affiliated Stockholder's name, to vote, express, consent or dissent,
or otherwise to utilize such voting power in the manner contemplated above as
Tekni-Plex or its proxy or substitute shall, in Tekni-Plex's sole discretion,
deem proper with respect to such Affiliated Stockholder's Subject Shares. The
proxy granted by each Affiliated Stockholder pursuant to the Stockholder Voting
Agreement is irrevocable and is granted in consideration of Tekni-Plex entering
into the Stockholder Voting Agreement and the Merger Agreement and incurring
certain related fees and expenses. The proxy granted by each Affiliated
Stockholder under the Stockholder Voting Agreement shall be automatically
revoked upon termination of the Voting Agreement.
 
AFFILIATED STOCKHOLDER LOANS
 
     Each Affiliated Stockholder has agreed to repay in full any amounts,
whether or not then due, borrowed from or otherwise owed to the Company or any
Subsidiary, prior to or simultaneously with the consummation of the Merger,
unless such amounts owed have been offset as provided in the following sentence.
Under the Stockholder Voting Agreement each Affiliated Stockholder has agreed
and consented to the Company and its Subsidiaries offsetting any amounts owed,
in any form (including, without limitation, any Merger Consideration or amounts
owed pursuant to the Merger Agreement), to such Affiliated Stockholder by the
Company or any Subsidiary, with any amounts owed by such Affiliated Stockholder
to the Company or any Subsidiary whether or not then due and payable.
 
TEKNI-PLEX OPTION
 
     Under the Stockholder Voting Agreement, each Affiliated Stockholder granted
Tekni-Plex an irrevocable option to purchase all of such Affiliated
Stockholder's Subject Shares at an Exercise Price of $3.50 per share, as
adjusted in certain circumstances. In addition, upon the written request of
Tekni-Plex, each Affiliated Stockholder has agreed to exercise its rights under
any options, warrants or other securities convertible into shares of Common
Stock (each, a "Convertible Security") immediately prior to the Merger. Any
Common
 
                                       42
<PAGE>   50
 
Stock issued upon the conversion of any Convertible Security shall be deemed to
be Subject Shares subject to the terms of the Stockholder Voting Agreement.
 
     Subject to the conditions set forth in the Stockholder Voting Agreement,
the Tekni-Plex Option may be exercised by Tekni-Plex, in whole or in part, at
any time or from time to time and on or prior to the later of (i) the thirtieth
day after the termination of the Merger Agreement and (ii) in the event an
Acquisition Proposal is made to the Company at any time prior to the 30th day
after the termination of the Merger Agreement, the ninetieth day after the
termination of the Merger Agreement (the "Option Expiry Date"), irrespective of
whether such termination resulted from a breach of Tekni-Plex's obligations
thereunder or Tekni-Plex's failure to obtain sufficient financing to consummate
the Merger. In the event Tekni-Plex wishes to exercise the Tekni-Plex Option for
all or some of the Subject Shares, Tekni-Plex has agreed to send a written
notice (the "Exercise Notice") to an escrow agent specifying the total number of
Subject Shares it wishes to purchase pursuant to such exercise and the place,
the date (not less than one nor more than 20 business days from the date of the
Exercise Notice), and the time for the closing of such purchase, provided that
such date and time may be earlier than one day after the Exercise Notice if
reasonably practicable.
 
CONDITIONS OF OBLIGATIONS TO SELL
 
     The obligation of each Affiliated Stockholder under the Stockholder Voting
Agreement to sell any Subject Shares to Tekni-Plex pursuant to the Tekni-Plex
Option is subject to the conditions that: (i) the representations and warranties
of Tekni-Plex contained in the Stockholder Voting Agreement shall be true and
correct in all material respects as of the date of the Stockholder Voting
Agreement; (ii) all waiting periods under the HSR Act applicable to the exercise
of the Tekni-Plex Option shall have expired or been terminated; and (iii) there
shall be no preliminary or permanent injunction or other order, decree or ruling
issued by a court of competent jurisdiction or by a governmental, regulatory or
administrative agency or commission, nor any statute, rule, regulation or order
promulgated or enacted by any governmental authority, prohibiting or otherwise
restraining the exercise of the Tekni-Plex Option.
 
NO PROXIES, SALES OR SOLICITATION
 
     Under the Stockholder Voting Agreement, each Affiliated Stockholder has
agreed that until the Option Expiry Date, except pursuant to the terms of the
Stockholder Voting Agreement, such Affiliated Stockholder shall not, without the
prior written consent of Tekni-Plex, directly or indirectly, (i) grant any
proxies or enter into any voting trust or other agreement or arrangement with
respect to the voting of any Subject Shares or (ii) sell, assign, transfer,
encumber or otherwise dispose of, or enter into any contract, option or other
arrangement or understanding with respect to the direct or indirect sale,
assignment, transfer, encumbrance or other disposition of, any Subject Shares.
In addition, each Affiliated Stockholder has agreed not to seek or solicit any
such sale, assignment, transfer, encumbrance or other disposition or any such
contract, option or other arrangement or understanding except as provided in the
Stockholder Voting Agreement and each Affiliated Stockholder agrees to notify
Tekni-Plex promptly, and to provide all details requested by Tekni-Plex, if such
Affiliated Stockholder shall be approached or solicited, directly or indirectly,
by any Person with respect to any of the foregoing. Furthermore, each Affiliated
Stockholder has agreed not to exercise any rights (including, without
limitation, under Section 262 of the DGCL) to demand appraisal of any Subject
Shares that may arise with respect to the Merger.

     On November 11, 1997, the last trading date prior to public announcement of
the execution of the Merger Agreement, the bid and asked sales prices of the
Common Stock, as quoted on The Nasdaq SmallCap Market, were $2.66 and $2.72 per
share, respectively. On January 22, 1998, the bid and asked prices of the Common
Stock, as reported on The Nasdaq SmallCap Market, were $3.22 and $3.25 per
share, respectively.
 
     Stockholders are urged to obtain current market quotations for the Common
Stock prior to making any decision with respect to the Merger.
 
     As of the Record Date, there were 31,272,372 shares of Common Stock
outstanding and 978 record holders of Common Stock.
 
     The Company has not paid any cash dividends in the last three fiscal years
and through the first quarter of fiscal year 1998 and does not anticipate paying
any cash dividends in the foreseeable future. The Company's ability to pay
dividends is subject to the Company's income, receipt of cash flow from
subsidiaries in the form of dividends or similar distributions, financial
condition and capital needs. The ability of the Company's subsidiaries to pay
cash dividends to the Company is restricted by various credit agreements and, in
the case of PS&T, the PS&T Credit Agreement and the PS&T Indenture. Due to these
restrictions in such agreements, the Company is effectively precluded from
currently paying any material cash dividend and does not anticipate doing so in
the foreseeable future.

                CERTAIN PROJECTIONS OF FUTURE OPERATING RESULTS
 
     The Company does not as a matter of course make public forecasts as to its
future financial performance and condition. However, in connection with its
discussions with Tekni-Plex and certain other Financial Investors and Strategic
Investors, the Company furnished Tekni-Plex and such potential equity investors
with certain data relating to projected future operating results, cash flows and
financial condition. The projections set forth below were included in the data
provided by the Company to Tekni-Plex and, in the case of 1997, include a
comparison of actual results versus the projections. These projections were not
prepared in compliance with the published guidelines of the American Institute
of Certified Public Accountants or the Commission regarding projections or
financial forecasts and are included herein only because such information was
provided to Tekni-Plex and such potential equity investors. These projections
constitute forward-looking statements and were based upon numerous assumptions.
Although the Company believes that such assumptions are reasonable, such
assumptions are inherently subject to significant uncertainties and
contingencies that are difficult or impossible to predict and are beyond the
Company's control. Accordingly, there can be no assurance, and no representation
or warranty is made, that the actual results of operations and financial
position achieved by the Company will not vary materially from the results of
operations and financial condition set forth in these projections. For a list of
important factors that, in the view of the Company, could cause actual results
to differ materially from those set forth in these projections, see
"Forward-Looking Statements." The projections set forth below have not been
adjusted to reflect the effects of the Merger and do not give effect to the
restriction on capital expenditures imposed by the Merger Agreement during the
period prior to completion of the Merger.

(1) EBITDA equals income from continuing operations before the sum of interest
    expense, income taxes, depreciation and amortization. This information is
    provided for informational purposes only and such measure should not be
    construed as an alternative to income from operations as an indicator of
    operating performance, or as an alternative to cash flows from operating
    activities as a measure of liquidity. EBITDA is a widely accepted financial
    indicator of a company's ability to incur and service debt. However, this
    measure of EBITDA may not be comparable to similar measures presented by
    other companies.
 
     The projections set forth above were prepared by the Company in December
1996 in connection with the Company's preparation of a 3 year plan (except for
1999 and 2000 net sales, income from operations and EBITDA which were updated in
August 1997). Forecasts of future financial performance and condition could
differ materially from the data set forth above if management were to prepare
projections based upon circumstances existing as of the date of this Proxy
Statement. None of the Company or Tekni-Plex intend or have any duty or
obligation to publicly disclose updates or revisions to any of the projections
set forth above which are made after the date hereof to reflect circumstances
existing or developments occurring after the preparation of such projections or
to reflect the occurrence of unanticipated events. The Company's independent
auditors have not examined or compiled the foregoing forward-looking statements
or applied any procedures with respect to such statements. Accordingly, such
auditors have not expressed any opinion or other form of assurance with respect
to such statements and assume no responsibility for them.

                          AGREEMENT AND PLAN OF MERGER
 
     AGREEMENT AND PLAN OF MERGER dated as of November 11, 1997 among PureTec
Corporation, a Delaware corporation (the "Company"), Plastic Specialties &
Technologies, Inc., a Delaware corporation ("PS&T"), Tekni-Plex, Inc., a
Delaware corporation ("Buyer"), and P.T. Holding, Inc., a Delaware corporation
and a wholly-owned subsidiary of Buyer ("Merger Subsidiary").
 
     WHEREAS, as a condition to Buyer's and Merger Subsidiary's willingness to
enter into this Agreement, simultaneously with the execution of this Agreement
Buyer is entering into a Stockholder Voting and Option Agreement (the "Voting
Agreement") with certain stockholders of the Company;
 
     WHEREAS, simultaneously with the execution of this Agreement, Buyer, at the
request of the Company and PS&T, is lending the Company $5,000,000 in exchange
for a Convertible Note (the "Convertible Note") in order to bridge finance
certain working capital needs of the Company and PS&T during the term of this
Agreement;
 
     In consideration for the various agreements contained herein, in the Voting
Agreement and in the Convertible Note, the parties hereto agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     Section 1.01  The Merger.  (a) At the Effective Time, Merger Subsidiary
shall be merged (the "Merger") with and into the Company in accordance with the
General Corporation Law of the State of Delaware (the "Delaware Law"), whereupon
the separate existence of Merger Subsidiary shall cease, and the Company shall
be the surviving corporation (the "Surviving Corporation"). At the election of
Buyer, the Merger may be structured so that the Company shall be merged with and
into Merger Subsidiary with the result that Merger Subsidiary shall be the
Surviving Corporation.
 
     (b) At the earliest time following satisfaction or, to the extent permitted
hereunder, waiver of all conditions to the Merger, the Company and Merger
Subsidiary will file a certificate of merger with the Secretary of State of the
State of Delaware and make all other filings or recordings required by Delaware
Law in connection with the Merger. The Merger shall become effective at such
time as the certificate of merger is duly filed with the Secretary of State of
the State of Delaware or at such later time as is specified in the certificate
of merger (the "Effective Time").
 
     (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities and duties of the Company and Merger
Subsidiary, all as provided under Delaware Law.
 
     (d) The Company hereby represents that its Board of Directors, at a meeting
duly called and held, has (i) unanimously determined that this Agreement and the
transactions contemplated hereby, including the Merger, are fair to and in the
best interest of the Company's stockholders, (ii) unanimously approved this
Agreement and the transactions contemplated hereby, including the Merger, which
approval satisfies in full the requirements of Delaware Law, and (iii)
unanimously resolved to recommend approval and adoption of this Agreement and
the Merger by its stockholders; provided, that such recommendation may be
withdrawn, modified or amended to the extent the Board of Directors of the
Company deems it necessary to do so in the exercise of its fiduciary obligations
to the Company's stockholders after being so advised by outside counsel. The
Company further represents that Schroder & Co. Inc. ("Schroders") has delivered
to the Company's Board of Directors its written opinion that the Merger
Consideration is fair to the holders of Shares from a financial point of view.
The Company has been advised that all of its directors and executive officers
currently intend to vote their Shares in favor of the approval and adoption of
this Agreement and the Merger.
 
                                       I-1
<PAGE>   61
 
     Section 1.02  Conversion of Shares.  At the Effective Time:
 
     (a) each outstanding share (each a "Share") of common stock, $0.01 par
value (the "Common Stock") of the Company held by the Company as treasury stock
or owned by Buyer or any subsidiary of Buyer immediately prior to the Effective
Time shall be canceled, and no payment shall be made with respect thereto;
 
     (b) each share of common stock of Merger Subsidiary outstanding immediately
prior to the Effective Time shall be converted into and become one share of
common stock of the Surviving Corporation with the same rights, powers and
privileges as the shares so converted and shall constitute the only outstanding
shares of capital stock of the Surviving Corporation; and
 
     (c) each Share outstanding immediately prior to the Effective Time shall,
except as otherwise provided in Section 1.02(a) or as provided in Section 1.04
with respect to Shares as to which appraisal rights have been exercised, be
converted into the right to receive $3.50 in cash, without interest (the "Merger
Consideration").
 
     Section 1.03  Surrender and Payment.  (a) Prior to the Effective Time,
Buyer shall appoint an agent (the "Exchange Agent") for the purpose of
exchanging certificates representing Shares for the Merger Consideration. Buyer
will make available to the Exchange Agent, as needed, the Merger Consideration
to be paid in respect of the Shares. For purposes of determining the Merger
Consideration to be made available, Buyer shall assume that no holder of Shares
will perfect his right to appraisal of his Shares. As soon as practicable after
the Effective Time, Buyer will send, or will cause the Exchange Agent to send,
to each holder of Shares at the Effective Time a letter of transmittal for use
in such exchange (which shall specify that the delivery shall be effected, and
risk of loss and title shall pass, only upon proper delivery of the certificates
representing Shares to the Exchange Agent).
 
     (b) Each holder of Shares that have been converted into a right to receive
the Merger Consideration, upon surrender to the Exchange Agent of a certificate
or certificates representing such Shares, together with a properly completed
letter of transmittal covering such Shares, will be entitled to receive the
Merger Consideration payable in respect of such Shares. Until so surrendered,
each such certificate shall, after the Effective Time, represent for all
purposes, only the right to receive such Merger Consideration.
 
     (c) If any portion of the Merger Consideration is to be paid to a Person
other than the registered holder of the Shares represented by the certificate or
certificates surrendered in exchange therefor, it shall be a condition to such
payment that the certificate or certificates so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such payment shall pay to the Exchange Agent any transfer or other
taxes required as a result of such payment to a Person other than the registered
holder of such Shares or establish to the satisfaction of the Exchange Agent
that such tax has been paid or is not payable. For purposes of this Agreement,
"Person" means an individual, a corporation, a limited liability company, a
partnership, an association, a trust or any other entity or organization,
including a government or political subdivision or any agency or instrumentality
thereof.
 
     (d) After the Effective Time, there shall be no further registration of
transfers of Shares. If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be canceled and
exchanged for the Merger Consideration provided for, and in accordance with the
procedures set forth, in this Article 1.
 
     (e) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) that remains unclaimed by the holders of
Shares six months after the Effective Time shall be returned to Buyer, upon
demand, and any such holder who has not exchanged his Shares for the Merger
Consideration in accordance with this Section prior to that time shall
thereafter look only to Buyer for payment of the Merger Consideration in respect
of his Shares. Notwithstanding the foregoing, Buyer shall not be liable to any
holder of Shares for any amount paid to a public official pursuant to applicable
abandoned property laws. Any amounts remaining unclaimed by holders of Shares
two years after the Effective Time (or such earlier date immediately prior to
such time as such amounts would otherwise escheat to or become property of any
governmental entity) shall, to the extent permitted by applicable law, become
the property of Buyer free and clear of any claims or interest of any Person
previously entitled thereto.
 
                                       I-2
<PAGE>   62
 
     (f) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) to pay for Shares for which appraisal rights
have been perfected shall be returned to Buyer, upon demand.
 
     Section 1.04  Dissenting Shares.  Notwithstanding Section 1.02, Shares
outstanding immediately prior to the Effective Time and held by a holder who has
not voted in favor of the Merger or consented thereto in writing and who has
demanded appraisal for such Shares in accordance with Delaware Law shall not be
converted into a right to receive the Merger Consideration, unless such holder
fails to perfect or withdraws or otherwise loses his right to appraisal. If
after the Effective Time such holder fails to perfect or withdraws or loses his
right to appraisal, such Shares shall be treated as if they had been converted
as of the Effective Time into a right to receive the Merger Consideration. The
Company shall give Buyer prompt notice of any demands received by the Company
for appraisal of Shares, and Buyer shall have the right to participate in all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of Buyer, make any payment with
respect to, or settle or offer to settle, any such demands.
 
     Section 1.05  Stock Options.  (a) At the Effective Time, each holder of an
outstanding stock option to purchase Shares, whether or not then vested or
exercisable, granted under any employee or director stock option or compensation
plan or arrangement of the Company shall be paid by the Company promptly upon
surrender of such stock option an amount determined by multiplying (i) the
excess, if any, of $3.50 per Share over the applicable exercise price per share
of such option by (ii) the number of Shares such holder could have purchased
(assuming full vesting of all options) had such holder exercised such option in
full immediately prior to the Effective Time.
 
     (b) Promptly following the Effective Time, the Company shall notify all
holders of outstanding options or warrants to purchase Shares other than those
referred to in subsection (a) above that such holders are entitled to receive
the Merger Consideration upon surrender of such options or warrants and payment
to the Company by the holder thereof of the applicable exercise price (and in
the case of options referred to in Section 1.05(a), of such right to receive the
payment described in Section 1.05(a) in lieu of exercising such option).
 
     Section 1.06  Company Debt.  (a) PS&T Senior Notes. The Company shall cause
PS&T to promptly commence a combined consent solicitation and offer to purchase
(the "Debt Offer"), in accordance with applicable law and pursuant to
documentation reasonably satisfactory to Buyer, any and all of PS&T's
outstanding 11.25% Senior Secured Notes due 2003 (the "PS&T Notes") at a cash
price to be specified by Buyer or at such other price as Buyer may specify from
time to time thereafter. The Company shall cause PS&T to purchase the PS&T Notes
tendered pursuant to the Debt Offer at the Effective Time. The Debt Offer shall
be subject to the conditions that (i) there shall be validly tendered and not
withdrawn in accordance with the terms of the Debt Offer prior to the expiration
date of the Debt Offer, PS&T Notes in an aggregate principal amount representing
at least a majority in principal amount of the PS&T Notes, (ii) the holders of
at least a majority in principal amount of the PS&T Notes shall have consented
prior to the Effective Time to amend the indenture dated as of October 29, 1993
between PS&T and First Fidelity Bank, N.A. Pennsylvania, as Trustee (the "PS&T
Indenture") to delete such covenants, events of default and other provisions of
the PS&T Indenture as Buyer shall specify and to make such other amendments to
the PS&T Indenture as Buyer may require, and (iii) Buyer shall have consummated
or, simultaneously with the consummation of the Debt Offer, shall consummate the
Merger.
 
     (b) Other Subsidiary Debt. Prior to or simultaneously with the consummation
of the Merger, the Company shall cause each of its Subsidiaries (as defined in
Section 3.06) to repay and retire such of its outstanding debt (other than any
PS&T Notes not tendered in the Debt Offer) as Buyer may require (it being
understood that Buyer may require the Company and its Subsidiaries to retire any
or all such debt).
 
     Section 1.07  PS&T Minority Interest.  The Company shall eliminate the
minority shareholders' interest in PS&T, either pursuant to an offer to purchase
such minority shares or pursuant to sec. 253 of the Delaware Law, at a price of
$7.00 per share of common stock of PS&T, at any time prior to but no later than
immediately prior to the consummation of the Merger.
 
                                       I-3
<PAGE>   63
 
     Section 1.08  Intercompany Loans.  Simultaneously with the consummation of
the Merger, Buyer shall loan to each of the Company and its Subsidiaries,
amounts sufficient to enable each of the Company and its Subsidiaries to comply
with its obligations under Sections 1.05, 1.06, and 1.07. The loans referred to
in this Section 1.08 are hereinafter referred to as the "Intercompany Loans".
The obligations of the Company and its Subsidiaries under Sections 1.05, 1.06,
and 1.07 are contingent upon receipt of Intercompany Loans in amounts sufficient
to discharge such obligations.
 
     Section 1.09  Upstream Guarantees.  Effective as of the Effective Time, the
Company shall and shall cause each of its domestic Subsidiaries to guarantee (i)
Buyer's 11 1/4% Senior Subordinated Notes due 2007, to the extent required by
the indenture dated as of April 1, 1997 among Buyer, Dolco Packaging Corp. and
Marine Midland Bank, as Trustee (the "Tekni-Plex Indenture"), and (ii) any
indebtedness of Buyer issued to finance the transactions contemplated hereby.
The guarantees to be issued pursuant to this Section 1.09 are hereinafter
referred to as the "Upstream Guarantees".
 
                                   ARTICLE II
 
                           THE SURVIVING CORPORATION
 
     Section 2.01  Certificate of Incorporation.  The certificate of
incorporation of Merger Subsidiary in effect at the Effective Time shall be the
certificate of incorporation of the Surviving Corporation until amended in
accordance with applicable law, except that the name of the Surviving
Corporation shall be changed to "PureTec Corporation".
 
     Section 2.02  Bylaws.  The bylaws of Merger Subsidiary in effect at the
Effective Time shall be the bylaws of the Surviving Corporation until amended in
accordance with applicable law.
 
     Section 2.03  Directors and Officers.  From and after the Effective Time,

applicable law, (a) the directors of Merger Subsidiary at the Effective Time

Company at the Effective Time shall be the officers of the Surviving

failure to be so qualified would not, individually or in the aggregate, have a
material adverse effect on the condition (financial or otherwise), business,
assets, results of operations or prospects of the Company and the Subsidiaries
taken as a whole (a "Material Adverse Effect"). The Company has heretofore
delivered to Buyer true and complete copies of the Company's certificate of
incorporation and bylaws as currently in effect.

Company or any Subsidiary for which the Company or any Subsidiary may be liable)
or any of their respective properties before any court or arbitrator or any

to the Company or any Subsidiary in accordance with the plaintiff's demands,
would reasonably be expected to have a Material Adverse Effect or which in any

Merger or any of the other transactions contemplated hereby.

     (b) Each of the products produced or sold by the Company or any Subsidiary
is, and at all times up to and including the sale thereof has been, (i) in
compliance in all material respects with all applicable federal, state, local
and foreign laws and regulations and (ii) fit for the ordinary purposes for
which it is intended to be used and conforms in all material respects to any
promises or affirmations of fact made on the container or label for such product
or in connection with its sale, except where such noncompliance or failure to be

expected to have a Material Adverse Effect. There is no design defect with
respect to any of such products and each of such products contains adequate
warnings, presented in a reasonably prominent manner, in accordance with
applicable including any schedule or attachment thereto, and including any
amendment thereof.
 
     (c) Except as disclosed in Schedule 3.13(b), each of the Company and its

Tax years ended prior to the date of this Agreement or requests for extensions
have been timely filed and any such request shall have been granted and not

respects, paid or accrued all material Taxes shown to be due and payable on such
Tax Returns and properly accrued in all material respects all such Taxes for

has been proposed, asserted or assessed against the Company or any Subsidiary
which has not been resolved and paid in full.
 
     (e) There are no outstanding requests, agreements, consents or waivers to

     (f) Except as disclosed in Schedule 3.13(e), neither the Company nor any
Subsidiary has been a member of any group of entities (other than a group of

     (g) Schedule 3.13(f) contains a complete and accurate list, as of July 31,
1996, of all of the accrued and unexpired net operating loss carryforward
amounts of the Company and its Subsidiaries and their corresponding annual
limitations under Section 382 of the Internal Revenue Code of 1986, as amended
(the "Code").
 
     Section 3.14  Employee Benefits.  (a) Schedule 3.14(a) sets forth a list of
each "employee benefit plan", as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974 ("ERISA"), which (i) is subject to any
provision of ERISA and (ii) is maintained, administered or contributed to by the
Company or any Subsidiary and covers any employee or former employee of the
Company or any Subsidiary or under which the Company or any Subsidiary has any
liability. Copies of such plans (and, if applicable, related trust agreements)
and all amendments thereto and written interpretations thereof have been
furnished to Buyer together with (A) the three most recent annual reports (Form
5500 including, if applicable, Schedule B thereto) prepared in connection with
any such plan and (B) the most recent actuarial valuation report prepared in
connection with any such plan. Such plans are referred to collectively herein as
the "Employee Plans". The only Employee Plans which individually or collectively
would constitute an "employee pension benefit plan" as defined in Section 3(2)
of ERISA (the "Pension Plans") are identified as such in the list referred to
above. The Company has provided Buyer with complete age, salary, service and
related data as of July 31, 1997 for employees and former employees of the
Company and any Subsidiary covered under the
 
                                       I-9
<PAGE>   69
 
Pension Plans. As of the Effective Time, no Employee Plan will provide for and
the Company will not be obligated to provide equity-based compensation or
benefits.
 
     (b) Except as otherwise identified in the list referred to in Section
3.14(a), no Employee Plan constitutes a "multiemployer plan", as defined in
Section 3(37) of ERISA (a "Multiemployer Plan"), and no Employee Plan is
maintained in connection with any trust described in Section 501(c)(9) of the
Code. The only Employee Plans that are subject to Title IV of ERISA (the
"Retirement Plans") are identified in the list of such Plans heretofore provided
to Buyer by the Company. Except as otherwise disclosed fully and specifically in
the Company 10-K in accordance with Statement of Financial Accounting Standards
("SFAS") No. 87, as of the Balance Sheet Date, the fair market value of the
assets of each Retirement Plan (excluding for these purposes any accrued but
unpaid contributions) exceeded the projected benefit obligation for such plan
determined in accordance with SFAS No. 87. No "accumulated funding deficiency",
as defined in Section 412 of the Code, has been incurred with respect to any
Pension Plan, whether or not waived. The Company knows of no "reportable event",
within the meaning of Section 4043 of ERISA, and no event described in Section
4041, 4042, 4062 or 4063 of ERISA has occurred in connection with any Employee
Plan, other than a "reportable event" that will not have a Material Adverse
Effect. The assets of the Company and all of its Subsidiaries are not now, nor
will they after the passage of time be, subject to any lien imposed under Code
Section 412(n) by reason of a failure of any of the Company or any Subsidiary to
make timely installments or other payments required under Code Section 412. No
condition exists and no event has occurred that could constitute grounds for
termination of any Retirement Plan or, with respect to any Employee Plan which
is a Multiemployer Plan, presents a material risk of a complete or partial
withdrawal under Title IV of ERISA and neither the Company nor any of its
affiliates has incurred any material liability under Title IV of ERISA arising
in connection with the termination of, or complete or partial withdrawal from,
any plan covered or previously covered by Title IV of ERISA, which liability has
not been paid in full. If a "complete withdrawal" by the Company and all of its
affiliates were to occur as of the Effective Time with respect to all Employee
Plans which are Multiemployer Plans, neither the Company nor any affiliate would
incur any withdrawal liability under Title IV of ERISA that would have or
reasonably be expected to have a Material Adverse Effect. Nothing done or
omitted to be done and no transaction or holding of any asset under or in
connection with any Employee Plan has or will make the Company or any
Subsidiary, any officer or director of the Company or any Subsidiary subject to
any liability under Title I of ERISA or liable for any tax pursuant to Section
4975 of the Code that could have a Material Adverse Effect.
 
     (c) To the Company's knowledge, each Employee Plan which is intended to be
qualified under Section 401(a) of the Code is so qualified and has been so
qualified during the period from its adoption to date, and each trust forming a
part thereof is exempt from tax pursuant to Section 501(a) of the Code. The
Company has furnished to the Buyer copies of the most recent Internal Revenue
Service determination letters with respect to each such Plan. Each Employee Plan
has been maintained in substantial compliance with its terms and with the
requirements prescribed by any and all statutes, orders, rules and regulations,
including but not limited to ERISA and the Code, which are applicable to such
Plan.
 
     (d) There is no contract, agreement, plan or arrangement covering any
employee or former employee of the Company or any Subsidiary that, individually
or collectively, could give rise to the payment of any amount that would not be
deductible pursuant to the terms of Section 280G of the Code.
 
     (e) Schedule 3.14(e) sets forth each written and material unwritten
employment, severance or similar contract or arrangement or any written or any
material unwritten plan, policy, fund, program or contract or arrangement of the
Company and its Subsidiaries providing for compensation, bonus, profit-sharing,
stock option, or other stock related rights or other forms of incentive or
deferred compensation, vacation benefits, insurance coverage (including any
self-insured arrangements), health or medical benefits, disability benefits,
workers' compensation, supplemental unemployment benefits, severance benefits
and post-employment or retirement benefits (including compensation, pension,
health, medical or life insurance or other benefits) which (i) is not an
Employee Plan, (ii) is entered into, maintained or contributed to, as the case
may be, by the Company or any of its Subsidiaries and (iii) covers any employee
or former employee of the Company or any of its Subsidiaries. Such contracts,
plans and arrangements as are described above, copies or descriptions of all of
which have been furnished previously to Buyer are referred to collectively
herein as the "Benefit
 
                                      I-10
<PAGE>   70
 
Arrangements". Each Benefit Arrangement has been maintained in substantial
compliance with its terms and with the requirements prescribed by any and all
statutes, orders, rules and regulations that are applicable to such Benefit
Arrangement.
 
     (f) The excess of the present value of the projected liability in respect
of post-retirement health and medical benefits for retired employees of the
Company and its affiliates, determined using assumptions that are reasonable in
the aggregate, over the fair market value of any fund, reserve or other assets
segregated for the purpose of satisfying such liability (including for such

                                      I-20
<PAGE>   80
 
date hereof, and Buyer will not amend, repeal or modify such provisions in any
manner that would adversely affect the rights thereunder of such persons;
provided that such indemnification shall be subject to any limitation imposed
from time to time under applicable law. For four years after the Effective Time,
Buyer will cause each of the Surviving Corporation and PS&T, respectively, to
use its best efforts to provide officers' and directors' liability insurance in
respect of acts or omissions occurring prior to the Effective Time covering each
such Person currently covered by the Company's and PS&T's officers' and
directors' liability insurance policy on terms with respect to coverage and
amount no less favorable in the aggregate than those of the applicable policy in
effect on the date hereof, provided that in satisfying its obligation under this
Section, Buyer shall not be obligated to cause the Surviving Corporation or PS&T
to purchase an amount of such insurance in excess of the amount that can be
purchased for premiums of 120% of the amount per annum the Company or PS&T paid
in its last full fiscal year, which amount has been disclosed to Buyer.

being satisfied, or (y) the amount of the Financing to be provided pursuant to
the Commitment Letters or the Financing Agreements not being sufficient to
complete all of the transactions contemplated hereby.
 
     Section 6.05  Repurchase of Bonds.  In the event that the consummation of
the Merger or the drawing of funds under the Financing Agreements would be
reasonably likely to violate or cause an event of default under the Tekni-Plex
Indenture, Buyer shall, at the earliest practicable time following Buyer's
obtaining knowledge thereof, notify the Company of such fact and commence a
combined consent solicitation and offer to purchase any and all of the 11 1/4%
Senior Subordinated Notes due 2007 issued thereunder. The documentation for such
offer and consent solicitation, including without limitation the conditions
thereto, shall be reasonably satisfactory to the Company, and Buyer shall take
all actions reasonably necessary in connection therewith to obtain the consent
of holders of the principal amount of notes which would be sufficient to amend
or eliminate those provisions of the Tekni-Plex Indenture which would be
contravened by the consummation of the Merger.

     Section 9.01  Termination.  This Agreement may be terminated and the Merger
may be abandoned at any time prior to the Effective Time (notwithstanding any
approval of this Agreement by the stockholders of the Company):
 
          (a) by mutual written consent of the Company and Buyer;

     consummated by March 31, 1998;
 
          (c) by either the Company or Buyer, if there shall be any law or
     regulation that makes consummation of the Merger illegal or otherwise
     prohibited or if any judgment, injunction, order or decree enjoining Buyer
     or the Company from consummating the Merger is entered and such judgment,
     injunction, order or decree shall become final and nonappealable; or
 
          (d) by Buyer, if any Person, entity or "group" (as defined in Section
     13(d)(3) of the Exchange Act) other than Buyer or Merger Subsidiary
     acquires beneficial ownership of 50% or more of the outstanding Shares;
 
          (e) by Buyer, if prior to the Effective Time, the Board of Directors

     Acquisition Proposal or entered into a definitive agreement or agreement in
     principle with respect to another Acquisition Proposal, or resolved to do
     any of the foregoing;
 
          (f) by Buyer, if prior to the consummation of the Merger, a tender or
     exchange offer for some or all of the Shares shall have been publicly
     proposed to be made or shall have been made by another person, or it shall
     have been publicly disclosed or Buyer shall have otherwise learned that any
     person, entity or "group" (as defined in Section 13(d)(3) of the Exchange
     Act) other than Buyer or Merger Subsidiary shall have acquired or proposed
     to acquire beneficial ownership of more than 20% of any class or series of
     capital stock of the Company (including the Shares), through the
     acquisition of stock, the formation of a group or otherwise, or shall have
     been granted any option, right or warrant, conditional or otherwise, to
     acquire beneficial ownership of more than 20% of any class or series of
     capital stock of the Company (including the Shares);

     communication from the Department of Justice or Federal Trade Commission
     (each an "HSR Authority") (which communication shall be confirmed to the
     other parties by the HSR Authority) that causes such party to reasonably
     believe that any HSR Authority has authorized the institution of litigation
     challenging the transactions contemplated by this Agreement under the U.S.
     antitrust laws, which litigation will include a motion seeking an order or
     injunction prohibiting the consummation of any of the transactions
     contemplated by this Agreement; and

          (i) by the Company, if (x) the Board of Directors of the Company
     concludes in good faith, based on written advice from outside counsel,
     that, in order to prevent the Board of Directors of the Company from
     breaching its fiduciary duties to the stockholders of the Company, it must

     recommendation, (y) the Company complies with its obligations under Section

                    STOCKHOLDER VOTING AND OPTION AGREEMENT
 
     AGREEMENT, dated as of November 11, 1997 between Tekni-Plex, Inc., a
Delaware corporation ("BUYER"), and the persons listed on the signature pages
hereto (each a "STOCKHOLDER" and collectively the "STOCKHOLDERS").
 
     WHEREAS, in order to induce Buyer and P.T. Holding, Inc., a Delaware
corporation and a wholly-owned subsidiary of Buyer ("MERGER SUBSIDIARY"), to
enter into an Agreement and Plan of Merger, dated as of the date hereof (the
"MERGER AGREEMENT"), with PureTec Corporation, a Delaware corporation (the
"COMPANY"), Buyer has requested the Stockholders, and the Stockholders have
agreed, to enter into this Agreement with respect to all shares of common stock,
par value $0.01 per share, of the Company (the "COMMON STOCK") that such
Stockholders beneficially own and any additional shares acquired by the
Stockholders (whether by purchase or otherwise) after the date of this Agreement
(the "SHARES").
 
     NOW, THEREFORE, the parties hereto agree as follows:
 
                                   ARTICLE 1
 
           GRANT OF PROXY; VOTING AGREEMENT; AGREEMENT TO REPAY LOANS
 
     Section 1.1.  Voting Agreement.  (a) Each Stockholder hereby agrees to vote
all Shares that such Stockholder is entitled to vote, in favor of the approval
and adoption of the Merger Agreement, the Merger and all agreements related to
the Merger and any actions related thereto at any meeting of the stockholders of
the Company, and at any adjournment thereof, at which such Merger Agreement and
other related agreements (or any amended version thereof), or such other
actions, are submitted for the consideration and vote of the stockholders of the
Company. Each Stockholder hereby agrees that, from the date hereof until the
earlier of (x) the consummation of the Merger and (y) the termination of the
Merger Agreement it will not vote any Shares in favor of the approval of any (i)
Acquisition Proposal, (ii) reorganization, recapitalization, liquidation or
winding up of the Company or any other extraordinary transaction involving the
Company, (iii) corporate action the consummation of which would frustrate the
purposes, or prevent or delay the consummation, of the transactions contemplated
by the Merger Agreement or (iv) other matter relating to, or in connection with,
any of the foregoing matters.
 
     (b) The Stockholders make no agreement or understanding herein in their
capacities as directors or officers of the Company. Each Stockholder signs
solely in his capacity as a recordholder and/or beneficial owner of Shares, and
nothing herein shall limit or affect any actions taken in such Stockholder's
capacity as an officer or director of the Company.
 
     Section 1.2.  Irrevocable Proxy.  Each Stockholder hereby revokes any and
all previous proxies granted with respect to the Shares. By entering into this
Agreement, each Stockholder hereby grants a proxy appointing Buyer as such
Stockholder's attorney-in-fact and proxy, with full power of substitution, for
and in such Stockholder's name, to vote, express, consent or dissent, or
otherwise to utilize such voting power in the manner contemplated by Section
1.01 above as Buyer or its proxy or substitute shall, in Buyer's sole
discretion, deem proper with respect to such Stockholder's Shares. The proxy
granted by each Stockholder pursuant to this Article 1 is irrevocable and is
granted in consideration of Buyer entering into this Agreement and the Merger
Agreement and incurring certain related fees and expenses. The proxy granted by
each Stockholder shall be automatically revoked upon termination of the voting
agreement of such Stockholder set forth in Section 1.01.
 
     Section 1.3.  Agreement to Repay Loans.  (a) Each Stockholder hereby agrees
to repay in full any amounts, whether or not then due, borrowed from or
otherwise owed to the Company or any Subsidiary prior to or simultaneously with
the consummation of the Merger, unless such amounts owed have been offset in
accordance with Section 1.03(b).
 
                                      II-1
<PAGE>   88
 
     (b) Each Stockholder hereby agrees and consents to the Company and its
Subsidiaries offsetting any amounts owed, in any form, (including, without
limitation, any Merger Consideration or amounts owed pursuant to Section 1.05(a)
of the Merger Agreement or the plans and programs referred to in Section 5.08 of
the Merger Agreement) to such Stockholder by the Company or any Subsidiary, with
any amounts owed by such Stockholder to the Company or any Subsidiary whether or
not then due and payable. Each Stockholder further agrees to fully cooperate
with Buyer to effect the offset described herein and to execute and deliver, or
cause to be executed and delivered, all further documents and instruments
necessary or advisable to effect such offset.
 
                                   ARTICLE 2
 
                                  STOCK OPTION
 
     Section 2.1.  Grant of Stock Option.  (a) Each Stockholder hereby grants to
Buyer an irrevocable option (the "OPTION") to purchase all of such Stockholder's
Shares at a purchase price of $3.50 per Share (the "PURCHASE PRICE").
 
     (b) Upon the written request of Buyer, each Stockholder agrees to exercise
its rights under any options, warrants or other securities convertible into
shares of Common Stock (each a "CONVERTIBLE SECURITY") immediately prior to the
Merger. Any Common Stock issued upon the conversion of any Convertible Security
shall be deemed to be Shares subject to the terms of this Agreement.
 
     Section 2.2.  Exercise of Option.  (a) Subject to the conditions set forth
in Section 2.05 hereof, the Option may be exercised by Buyer, in whole or in
part, at any time or from time to time after the date hereof and on or prior to
the later of (i) the 30th day after the termination of the Merger Agreement and
(ii) in the event an Acquisition Proposal is made to the Company at any time
prior to the 30th day after the termination of the Merger Agreement, the 90th
day after the termination of the Merger Agreement (the "OPTION EXPIRY DATE"). In
the event Buyer wishes to exercise the Option for all or some of the Shares,
Buyer shall send a written notice (the "EXERCISE NOTICE") to the Escrow Agent
(as defined in Section 2.04) specifying the total number of Shares it wishes to
purchase pursuant to such exercise and the place, the date (not less than one
nor more than 20 business days from the date of the Exercise Notice), and the
time for the closing of such purchase, provided that such date and time may be
earlier than one day after the Exercise Notice if reasonably practicable. Each
closing of a purchase of Shares (an "OPTION CLOSING") shall take place at the
place, on the date and at the time designated by Buyer in its Exercise Notice,
provided that if, at the date of the Option Closing herein provided for, the
conditions set forth in Section 2.05 shall not have been satisfied (or waived by
the Stockholder), Buyer may postpone the Option Closing until a date within five
business days after such conditions are satisfied.
 
     (b) Buyer shall not be under any obligation to deliver any Exercise Notice
and may allow the Option to terminate without purchasing any Shares hereunder;
provided however that once Buyer has delivered to the Stockholders an Exercise
Notice, subject to the terms and conditions of this Agreement, Buyer shall be
bound to effect the purchase as described in such Exercise Notice.
 
     Section 2.3.  Option Closing.  (a) Each Stockholder shall cause the Escrow
Agent to deliver to Buyer a certificate or certificates (the "CERTIFICATES")
representing (or cause to be made book entry delivery to an account designated
by Buyer of) such Stockholder's Shares, in the case of certificates, duly
endorsed or accompanied by stock powers duly executed in blank and (b) Buyer
shall deliver to each Stockholder a certified or bank cashier's check or checks
payable to or upon the order of such Stockholder in an amount equal to (i) the
number of Shares being purchased from such Stockholder at such Option Closing
multiplied by (ii) the Purchase Price (the "PURCHASE AMOUNT").
 
     Section 2.4.  Deposit in Escrow.  Upon request, each Stockholder shall
execute and deliver to the Buyer and the escrow agent (the "ESCROW AGENT") a
copy of an Escrow Agreement substantially in the form attached hereto as Annex A
with such modifications as the Escrow Agent may require (the "ESCROW AGREEMENT")
and deliver a certificate or certificates representing (or cause book entry
delivery to be made to an account designated by the Escrow Agent of) all of such
Stockholder's Shares to the Escrow Agent, duly
 
                                      II-2
<PAGE>   89
 
endorsed in blank for transfer pursuant to the Escrow Agreement. In addition,
each Stockholder shall promptly deliver certificates representing any additional
Shares acquired after the date hereof to the Escrow Agent, duly endorsed in
blank for transfer pursuant to the Escrow Agreement. All Shares so delivered to
the Escrow Agent shall remain subject to the Escrow Agreement until the earlier
of (i) the purchase of such Shares by the Buyer hereunder or (ii) the expiry of
the Option.
 
     Section 2.5.  Conditions to Stockholders' Obligations.  The obligation of
each Stockholder to sell Shares at any Option Closing is subject to the
following conditions:
 
          (a) The representations and warranties of Buyer contained in Article 4
     shall be true and correct in all material respects on the date thereof.
 
          (b) All waiting periods under the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended, and the rules and regulations
     promulgated thereunder (the "HSR ACT") applicable to such exercise of the
     Option shall have expired or been terminated.
 
          (c) There shall be no preliminary or permanent injunction or other
     order, decree or ruling issued by a court of competent jurisdiction or by a
     governmental, regulatory or administrative agency or commission, nor any
     statute, rule, regulation or order promulgated or enacted by any
     governmental authority, prohibiting or otherwise restraining such exercise
     of the Option.
 
     Section 2.6.  Adjustment Upon Change in Capitalization or Merger.  In the
event of any change in the Company s capital stock by reason of stock dividends,
stock splits, mergers, consolidations, recapitalizations, combinations,
conversions, exchanges of shares, extraordinary or liquidating dividends, or
other changes in the corporate or capital structure of the Company which would
have the effect of diluting or changing the Buyer s rights hereunder (excluding
any effects of conversion of the Convertible Note), the number and kind of
shares or securities subject to the Option and the purchase price per Share (but
not the total purchase price) shall be appropriately and equitably adjusted so
that the Buyer shall receive upon exercise of the Option the number and class of
shares or other securities or property that the Buyer would have received in
respect of the Shares purchasable upon exercise of the Option if the Option had
been exercised immediately prior to such event. Each Stockholder shall take such
steps in connection with such consolidation, merger, liquidation or other such
action as may be necessary to assure that the provisions hereof shall thereafter
apply as nearly as possible to any securities or property thereafter deliverable
upon exercise of the Option.
 
                                   ARTICLE 3
 
                 REPRESENTATIONS AND WARRANTIES OF STOCKHOLDERS
 
     Each Stockholder represents and warrants to Buyer that:
 
     Section 3.1.  Authorization.  If such Stockholder is a corporate entity,
the execution, delivery and performance by such Stockholder of this Agreement
and the consummation by such Stockholder of the transactions contemplated hereby
are within the corporate powers of such Stockholder and have been duly
authorized by all necessary corporate action. If such Stockholder is married and
the Shares set forth on the signature page hereto opposite such Stockholder's
name constitute community property under applicable laws, this Agreement has
been duly authorized, executed and delivered by, and constitutes the valid and
binding agreement of, such Stockholder s spouse. If this Agreement is being
executed in a representative or fiduciary capacity, the Person signing this
Agreement has full power and authority to enter into and perform this Agreement.
 
     Section 3.2.  Non-Contravention.  The execution, delivery and performance
by such Stockholder of this Agreement and the consummation of the transactions
contemplated hereby do not and will not (i) if such Stockholder is a

                                ESCROW AGREEMENT
 
     AGREEMENT dated as of                  , 19  among Tekni-Plex, Inc., a

receipt of the certificate and evidence provided for paragraph 2(a) above in
accordance with this Section 2, notwithstanding any claim given to, or demand
made upon, the Escrow Agent or any action taken or threatened to be taken by any
other person or entity. The Escrow Agent's obligation to so deliver such
Certificates shall survive the death, disability, incapacity, incompetence or
other circumstance relating to the Stockholder.
 
     (c) The Buyer will deliver simultaneously to the Stockholder copies of all
certificates, evidences and instructions delivered to the Escrow Agent
hereunder.
 
     3. Except pursuant to the terms and conditions of this Agreement or by

notice of, any agreement out of which this escrow may arise, including but not
limited to the Stockholder Agreement.

of the other parties hereof, or any one of them, to perform or comply with the
provisions of this Agreement or the Stockholder Agreement.
 
     7.  In the performance of its duties hereunder, the Escrow Agent shall be
entitled to rely upon any document, instrument or signature believed by it in
good faith to be genuine and signed by any party hereto or an authorized officer
or agent thereof, and shall not be required to investigate the truth or accuracy
of any statement contained in any such document or instrument. The Escrow Agent
may assume that any person purporting to give any notice in accordance with the
provisions hereof has been duly authorized to do so.
 
     8.  The Escrow Agent shall not be liable for any error or judgment, or any
action taken, suffered or omitted to be taken hereunder except in the case of

been selected with reasonable care.
 
     9.  The Escrow Agent shall have no responsibility as to the validity or
value of the Shares. The Escrow Agent shall have no duty as to the collection or

such securities actually in its possession.
 
     10.  The Escrow Agent or any successor to it as escrow agent hereafter
appointed may at any time resign and be discharged of the duties imposed
hereunder by giving notice to each of the parties hereto, such resignation to
take effect upon a successor escrow agent's acceptance of appointment.
 
     11.  Upon execution of this Agreement, the Escrow Agent shall receive an
acceptance fee in the amount to which the Escrow Agent and Buyer have heretofore
agreed together with reasonable attorney's fees incurred in connection with the
preparation of this Agreement.

it harmless against, any loss, liability or expense, including, but not limited
to, reasonable attorney's fees, incurred without negligence or willful
misconduct on the part of the Escrow Agent arising our of or in connection with
the acceptance of, or the performance of its duties and obligations under, this
Agreement, as well as the reasonable costs and expenses of defending itself
against any claim or liability arising out of or relating to this Agreement.
 
     13.  All notices, requests, demands and other communications provided for
by this Agreement (unless otherwise specified herein) shall be in writing and
delivered by mail, telegram, telex or personal delivery and shall be given to

     16.  This Agreement may be amended, modified, superseded or canceled, and
any of the terms hereof may be waived, only by written instrument executed by
the parties hereto or, in the case of a waiver, by the party waiving compliance.
The failure of any party at any time to require performance of any provision
hereof shall in no manner affect the right at a later time to enforce the same.
No waiver by any party of any breach of any term contained in this Agreement
shall be deemed to be or construed as a further or continuing waiver of any such
breach in any subsequent instance or a waiver of any breach of any other term
contained in this Agreement.
 
     17.  This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
 
     18.  Capitalized terms used herein shall have the meanings ascribed to such
terms in the Stockholder Agreement.

The Board of Directors
PureTec Corporation
65 Railroad Avenue
Ridgefield, New Jersey 07657
 
Members of the Board of Directors:
 
     We understand that PureTec Corporation (the "Company") is contemplating a
transaction pursuant to which Tekni-Plex, Inc. ("Tekni-Plex") would acquire all
of the outstanding shares (the "Shares") of Common Stock of the Company (the
"Transaction"). The Transaction acquisition will be effected through a merger
(the "Merger") of P.T. Holding Inc. ("Acquisition Corp."), a wholly-owned
subsidiary of Tekni-Plex, with the Company pursuant to which, among other
things, (i) the Company would become a wholly owned subsidiary of Tekni-Plex,
(ii) each outstanding Share (other than treasury shares) will be converted into
the right to receive $3.50 in cash (the "Transaction Consideration"), and (iii)
concurrent with the consummation of the Merger, the holder of each outstanding
option to purchase Shares not previously exercised would receive in cash, upon
cancellation of such option, the positive difference, if any, between $3.50 and
the exercise price per share of such option.
 
     In connection with the Transaction, the Company will cause its 96% owned
subsidiary, Plastic Specialties and Technologies, Inc. ("PS&T"), to commence a
combined consent solicitation and offer to purchase any and all of PS&T's
outstanding 11.25% Senior Secured Notes (the "PS&T Notes") (the "Debt Offer").
The Debt Offer is subject to various conditions, including (i) that there shall
be validly tendered and not withdrawn in accordance with the terms of the Debt
Offer, at least a majority in principal amount of the PS&T Notes, (ii) that the
holders of at least a majority in principal amount of the PS&T Notes shall have
consented to amend the indenture pursuant to which the PS&T Notes have been
issued to delete such covenants, events of default and other provisions as
Tekni-Plex shall specify and to make such other amendments as Tekni-Plex may
require, and (iii) that the Merger shall occur simultaneously therewith. In
addition, prior to or simultaneously with the consummation of the Merger, the
Company will be required to (i) cause each of its subsidiaries to pay and retire
such of its outstanding debt as Tekni-Plex may require and (ii) purchase or
eliminate the interests of the minority common stockholders in PS&T. The
financing for all of the transactions described above is to be arranged by
Tekni-Plex and is a condition to consummation of the Merger.
 
     Tekni-Plex has also agreed to provide up to $5.0 million of bridge
financing to the Company upon execution of the Merger Agreement (the "Bridge
Financing") in the form of a note which is convertible into Common Stock of the
Company if the Merger is not consummated. The terms and conditions of the
Transaction are more fully described in the proposed Agreement and Plan of
Merger among the Company, Tekni-Plex and Acquisition Corp. (the "Merger
Agreement").
 
     You have requested that Schroder & Co. Inc. ("Schroders") render an opinion
(the "Opinion"), as investment bankers, as to the fairness, from a financial
point of view, of the consideration to be received by the stockholders of the
Company other than Tekni-Plex, Acquisition Corp. and their affiliates in the
Transaction (the "Transaction Consideration").
 
                             [SCHRODERS LETTERHEAD]
                                      III-1

     Schroders, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for estate,
corporate and other purposes. We have, in the past, provided investment banking
services to the Company and have received customary fees for rendering such
services. In October 1993, Schroders managed a public offering for PS&T of the
PS&T Notes. Schroders has acted as financial advisor to the Company with respect
to the Transaction for which we have received fees and will receive additional
fees, contingent upon consummation of the Transaction.
 
     In connection with the Opinion set forth herein, we have, among other
things:
 
     i.   reviewed a draft, dated November 4, 1997, of the Merger Agreement;
 
     ii.  reviewed drafts of the bank commitment letters received by Tekni-Plex
          in connection with the financing for the Transaction and the Bridge
          Financing;
 
     iii.  reviewed a draft of the Company's Annual Report on Form 10-K filed
           with the Securities and Exchange Commission for the fiscal year ended
           July 31, 1997, including the audited consolidated financial
           statements of the Company included therein;
 
     iv.  reviewed historical financial results of the Company by subsidiary and
          operating division prepared by management;
 
     v.  reviewed forecasts and projections for the Company prepared or supplied
         by management of the Company for the fiscal years ending July 31, 1998
         through July 31, 2000;
 
     vi.  held discussions with the Company's management regarding the business,
          operations and prospects of the Company and each of its subsidiaries
          and operating divisions;
 
     vii.  visited PureTec's facilities in Ridgefield and Rockaway, New Jersey;
 
     viii. initiated contacts with a number of other third parties during the
           period May 1997 to September 1997 and advised the Company regarding
           other potential transactions;
 
     ix.  performed various valuation analyses, as we deemed appropriate, of the
          Company using generally accepted analytical methodologies, including
          (i) the application to the financial results of the Company of the
          public trading multiples of companies which we deemed comparable; (ii)
          the application to the financial results of the Company of the
          multiples reflected in recent mergers and acquisitions for businesses
          which we deemed comparable; (iii) a discounted cash flow analyses of
          the Company's operations; and (iv) a leveraged buyout analysis;
 
     x.  reviewed the historical trading prices and volumes of the Company's
         Common Stock; and
 
     xi.  performed such other financial studies, analyses, inquiries and
          investigations as we deemed appropriate.
 
     In rendering the Opinion, we have assumed and relied upon the accuracy and
completeness of all information supplied or otherwise made available to us by
the Company or obtained by us from other sources, and upon the assurance of the
Company's management that they are not aware of any information or facts that
would make the information provided to us incomplete or misleading. We have not
independently verified such information, undertaken an independent appraisal of
the assets or liabilities (contingent or otherwise) of the Company, or been
furnished with any such appraisals. With respect to financial forecasts for the
Company, we have been advised by the Company, and we have assumed, without
independent investigation, that they have been reasonably prepared and reflect
the best currently available estimates and judgment as to the expected future
financial performance of the Company.
 
                             [SCHRODERS LETTERHEAD]

     The Opinion is necessarily based upon financial, economic, market and other
conditions as they exist, and the information made available to us, as of the
date hereof. We disclaim any undertakings or obligations to advise any person of
any change in any fact or matter affecting the Opinion which may come or be
brought to our attention after the date of the Opinion.
 
     In the ordinary course of our business, we may hold and actively trade debt
or equity securities of the Company (including the Shares) for our own account
or for the accounts of our customers and, accordingly, may at any time hold a
long or short position in such securities.
 
     The Opinion does not constitute a recommendation as to any action the Board
of Directors of the Company or any stockholder of the Company should take in
connection with the Transaction or any aspect thereof. The Opinion relates
solely to the fairness from a financial point of view of the Transaction
Consideration to the stockholders of the Company other than Tekni-Plex,
Acquisition Corp. and their affiliates. We express no opinion herein as to the
structure, terms or effect of any other aspect of the Transaction or as to the
merits of the underlying decision of the Company to enter into the Transaction.
 
     This letter is for the information of the Board of Directors of the Company
for its use in evaluating the fairness from a financial point of view of the
Transaction Consideration to the stockholders of the Company other than
Tekni-Plex, Acquisition Corp. and their affiliates. It may not be used for any
other purpose or referred to without our prior written consent.
 
     Based upon and subject to all of the foregoing, we are of the opinion, as
investment bankers, that the Transaction Consideration is fair, from a financial
point of view, to the stockholders of the Company other than Tekni-Plex,
Acquisition Corp. and their affiliates.
 
                                          Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW
 
SEC. 262 APPRAISAL RIGHTS
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied

merger or consolidation nor consented thereto in writing pursuant to sec.228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series

        paragraph; or
 
             d.  Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger. Appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec.228 or
     sec.253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.
 
                                      IV-2

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may. in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal fights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
 
                                      IV-3
<PAGE>   103
 
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
