ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
     On April 12, 1999, pursuant to a Contribution Agreement (the "Contribution
Agreement") dated as of January 25, 1999, among Tenneco Packaging Inc., a wholly
owned subsidiary of Tenneco Inc. ("TPI"), PCA Holdings LLC, an affiliate of
Madison Dearborn Partners, Inc. ("PCA Holdings") and Packaging Corporation of
America, TPI completed the contribution of the containerboard assets of its
Paperboard Packaging business to a new joint venture with PCA Holdings in
exchange for cash and debt assumption totaling approximately $2.0 billion and a
45% common equity interest in the joint venture, which interest is valued at
approximately $200 million. The consideration received in the transaction was
determined through arms-length negotiations with Madison Dearborn Partners, Inc.
The containerboard assets represent substantially all of the assets of the
Paperboard Packaging segment and include four mills, 67 corrugated products
facilities and an ownership or controlling interest in approximately 950,000
acres of timberland. Paperboard Packaging's folding carton business was not
included in the transaction. The new joint venture entity (called Packaging
Corporation of America) will be headed by Paul T. Stecko, serving as its
chairman and chief executive officer. Upon closing of the transaction, Mr.
Stecko resigned his position as president and chief operating officer of Tenneco
Inc., but will continue to serve on Tenneco Inc.'s Board of Directors.

               UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Condensed Financial Statements of Tenneco
Inc. and Consolidated Subsidiaries ("Tenneco") illustrate the effects of the
contribution of the containerboard assets of Tenneco's Paperboard Packaging
segment to a new joint venture with PCA Holdings LLC, an affiliate of Madison
Dearborn Partners, Inc. ("PCA Holdings"). The following events occurred prior to
or as a part of the transaction: (i) Tenneco Packaging Inc., a wholly owned
subsidiary of Tenneco Inc. ("TPI"), borrowed $1,760 million; (ii) TPI used
$1,108 million of the debt proceeds to acquire containerboard mill and
timberland assets previously used by the containerboard business pursuant to
operating leases; (iii) TPI used approximately $150 million of the debt proceeds
to purchase containerboard business accounts receivable that had been sold to a
third party; and (iv) TPI contributed the containerboard assets, subject to the
new indebtedness and the existing containerboard business liabilities, to the
joint venture with PCA Holdings in exchange for $247 million in cash and a 45%
common equity interest in the venture valued at approximately $200 million.
Following the completion of the transaction, TPI remitted the net cash proceeds
of approximately $720 million to Tenneco Inc. Tenneco Inc. used the proceeds to
retire short-term debt.
 
     The Unaudited Pro Forma Condensed Balance Sheet has been prepared as if
such events and transactions occurred on December 31, 1998. The Unaudited Pro
Forma Condensed Statement of Income has been prepared as if such events and
transactions occurred as of January 1, 1998.

Tenneco's Annual Report on Form 10-K for the year ended December 31, 1998. The
Unaudited Pro Forma Condensed Financial Statements are not necessarily
indicative of actual operating results or financial position had the events and

                  Re:      Contribution Agreement

Gentlemen:

                  Reference is made to that certain Contribution Agreement,
dated as of January 25, 1999 (the "Contribution Agreement"), among Tenneco
Packaging Inc. ("TPI"), PCA Holdings LLC ("PCA"), and Packaging Corporation of
America ("Newco"). Capitalized terms used in this letter agreement not defined
herein shall have the meanings set forth in the Contribution Agreement.

                  The purpose of this letter agreement is to correct certain
errors or ambiguities that were included in the Contribution Agreement, and to
reflect the parties' agreements with respect to certain other matters, to the
extent those agreements differ form the terms of the Contribution Agreement

                  1.  The definition of "Assumed Indebtedness" in the 
         Contribution Agreement refers to the definition set forth in the
         Preliminary Statements. The definition of "Assumed Indebtedness" in the
         Preliminary Statements of the Contribution Agreement was inadvertently
         deleted in preparing the Contribution Agreement. The parties agree
         that, as used in the Contribution Agreement, the term "Assumed
         Indebtedness" shall mean (i) the $1.21 billion borrowed by TPI under
         the Term Loan Facilities and (ii) the $550 million promissory note
         issued by TPI to J.P. Morgan Securities, Inc. (the "Morgan Interim
         Note"), each of which will be assigned to and assumed by Newco at
         Closing.

                  2.  TPI, PCA, and Newco each hereby agree that the amount of
         the Term Loan Facilities and the Senior Subordinated Notes, and the
         terms of the Deferred-Pay Financing shall be on the terms set forth in
         the Offering Memorandum dated March 30, 1999,



<PAGE>   2

         notwithstanding that such amounts and terms differ from those set forth
         in the Contribution Agreement.

                  3.  TPI agrees that the Term Loan Facilities, pursuant to 
         which TPI will initially borrow $1.21 billion and which indebtedness
         will be assigned to and assumed by Newco as part of the Assumed
         Indebtedness, may, until the time of such assignment and assumption, be
         secured by certain depositary accounts and timberland assets of TPI, on
         terms satisfactory to TPI, notwithstanding that the Contribution
         Agreement provides for such loan to be unsecured as to TPI and that
         such security interest shall be released contemporaneously with the
         assignment and assumption by Newco.

                  4.  The parties agree that the Senior Subordinated Notes will
         not be issued by TPI, but that TPI will instead borrow $550 million
         pursuant to the Morgan Interim Note that will be assigned to and
         assumed by Newco as part of the Assumed Indebtedness, and which
         indebtedness will be repaid by Newco at the Closing.

                  5.  PCA hereby waives its right to elect, pursuant to Section
         5.16 of the Contribution Agreement, to instruct TPI to retain the
         Campbell Road Property, and agrees that the Campbell Road Property
         will, for purposes of the Contribution Agreement, constitute Owned Real
         Property and will be conveyed to Newco at Closing.

                  6.  Newco agrees that for a period of one year following the
         Closing Date TPI may (a) continue to use the PCA Marks on Corrugated
         Products purchased by TPI or its Affiliates from Newco pursuant to the
         Supply Agreements, until changes can be made to plates, molds, and
         similar items so as to allow Newco to produce such materials for TPI
         and such Affiliates without such PCA Marks, and (b) use the PCA marks
         on Corrugated Products that are in existence as of the Closing Date.
         Subject to the preceding sentence, TPI shall cease using the PCA Marks
         as soon as possible after Closing during such one year period and,
         following such one year period, TPI shall cease all use of any PCA
         Marks.

                  7.  PCA waives the condition to Closing set forth in Section
         6.2(g) of the Contribution Agreement, to the extent such closing
         condition would require PCA and Mr. Stecko to enter into any agreement
         beyond the letter agreement referred to therein, as such letter
         agreement may be modified.

                  8.  TPI hereby agrees and acknowledges that it has not 
         delivered a Dilution Notice pursuant to Paragraph E of the Preliminary
         Statements of the Contribution Agreement. PCA and TPI hereby agree
         that, notwithstanding anything in the Contribution Agreement to the
         contrary, upon issuance of Management Stock during the 120-day period
         following the Closing, Newco shall simultaneously redeem or purchase
         from PCA and TPI an aggregate number of Common Stock shares equal to
         the aggregate numbers of shares of Management Stock purchased during
         such 120-day period in a ratio of 55 shares from PCA to 45 shares from
         TPI at a price per share equal to the price per share paid by the
         Persons purchasing such Management Stock (provided such price per share
         is equal to the price per share paid for Common Stock purchased by PCA
         at Closing).

                  9.  The following changes are made to the definition of
         "Retained Liabilities": (A) paragraph (ix) is amended by adding the
         words "subject to paragraph (xiv) of this definition" after the word
         "Agreement" in clause (ii) thereof; and (B) a new paragraph (xiv) is
         added, a follows: "(xiv) all liability to make severance payments to
         seven named individuals who will be transferred to PCA and who have
         been identified to Newco and TPI in an aggregate amount of up to
         $385,000."

                  10. TPI has provided the Michigan Department of Natural
         Resources with a letter of credit in connection with certain operations
         at the Filer City Mill. TPI agrees to leave such letter of credit in
         place for 30 days after Closing or until Newco provides the Michigan
         Department of Natural Resources with a replacement letter of credit.
         Newco agrees to obtain and post such a replacement letter of credit
         within such 30-day period. Newco shall reimburse TPI for any draws made
         under TPI's letter of credit from and after Closing.

                  11. PCA and Newco hereby waive the closing condition set forth
         in Section 5.14(ii) of the Contribution Agreement, and TPI agrees at
         its sole expense to implement the steps set forth in Rick West's
         memorandum dated April 7, 1999, entitled "Form S-4 Exchange Option and
         Quarterly Filings," relating to the preparation of the quarterly
         financial statements referred to in Section 5.14(ii) of the
         Contribution Agreement provided that TPI hereby covenants it will
         deliver to PCA the financial statements referred to in Section 5.14(ii)
         of the Contribution Agreement (a) for the quarter ended March 31, 1998,
         no later than May 10, 1999 and (b) for each of the other quarters of
         1998, no later than May 31, 1999. Newco agrees that it will cause its
         appropriate financial officers and employees to provide reasonable
         assistance to TPI in its preparation of the financial statements
         referenced in this paragraph 11.

                  12. TPI hereby certifies that during the period from and
         including January 25, 1999 and the Closing, TPI has complied in all
         material respects with and not breached Section 5.2 of the Contribution
         Agreement.

                  13. TPI agrees to obtain, at its expense, for Newco commencing

         Administrative Transition Services Agreement (the "Transition
         Expiration Date"), licenses to use the following software, which
         licenses shall be substantially commensurate with the licenses to such

         and term as described in such existing licenses):

                  15. TPI's sole obligation pursuant to paragraphs 13 and 14

         the name of Newco, and shall not extend to any other fees, maintenance,

         Agreement or any Ancillary Agreement to pay for any other license to

         the Transition Services Agreement, other than those licenses expressly
         described in paragraphs 13 or 14.

                  16. TPI , PCA and Newco hereby stipulate that the definition 
         of "Retained Liabilities" shall include all liabilities arising from,
         related to or incurred in connection with any state of facts or
         conditions or transactions (or series of facts, conditions or

         Credit Corporation v. Tenneco Packaging, Inc. filed in the Circuit
         Court of Cook County, Illinois 99CH4738 (the "Lawsuit") or (ii) the
         Master Lease Agreement between IFC Credit Corporation and TPI (f/k/a/
         Packaging Corporation of America) that is the subject of the Lawsuit,
         in each case other than liabilities to the extent arising from, related
         to or incurred in connection with any breach by Newco of its
         obligations under this paragraph 16. Newco agrees to cease using the
         equipment that is the subject of the Lawsuit (the "Equipment") and
         return the Equipment where directed by TPI as soon as reasonably
         practical, and in no event will Newco use the Equipment after (and it
         will return the Equipment by) June 30, 1999. Newco shall use its

                  (i)      The general business direction, policies and programs
                           for Newco and its Subsidiaries during such period;

                  (ii)     A budget for Newco and its Subsidiaries for such

                           will make any expenditures in connection with

                           which shall be the initial Annual Business Plan.

The Board is expressly empowered to delegate to the management of Newco the
responsibility for the initial preparation of each Annual Business Plan, subject
to the final approval of each such plan by the Board as provided herein.

                  (b) EFFECT OF ANNUAL BUSINESS PLAN. The parties agree that the
business and operations of Newco and its Subsidiaries will be conducted in  
accordance with the applicable Annual Business Plan in all material respects and
in compliance with SECTION 3.6 hereof.

                                  ARTICLE III
                               BOARD OF DIRECTORS

                  3.1 GENERAL. From and after the Closing, each Stockholder will
vote all of its respective Shares and any other Voting Stock over which it
possesses direct or indirect voting power and will take all other necessary or
desirable actions within its direct or indirect control (whether in its capacity
as a stockholder of Newco or otherwise), and Newco will take all necessary and
desirable actions within its control, in order to give effect to the provisions
of this ARTICLE III. By way of example and without limiting the generality of
the foregoing, TPI and PCA shall amend the Certificate of Incorporation or
By-laws or both, as applicable, of Newco and each Subsidiary to incorporate and
effectuate the provisions in this ARTICLE III and to authorize and designate the
Junior Preferred Stock for the purpose of implementing the provisions relating
to the CEO Director as 


                                      -6-

<PAGE>   8

provided herein. With respect to the enumeration of the matters in SECTION 3.6 
below, such matters shall be set forth in the By-laws (and not the Certificate 
of Incorporation) except with respect to the establishment of committees of the 
Board and each Subsidiary Board and the dissolution of Newco, which matters 
shall be set forth in the Certificate of Incorporation.

                  3.2 POWERS. Subject to the provisions of the DGCL, the  
Certificate of Incorporation of Newco, the By-laws of Newco and this Agreement,
the  business and affairs of Newco shall be managed by or under the direction of
the Board.

                  3.3 SIZE AND COMPOSITION. The Board shall consist of six
individuals as follows: (i) two directors shall be designated in writing by TPI;
(ii) three directors shall be designated in writing by PCA; and (iii) the
remaining director shall be the Chief Executive Officer of Newco (the "CEO
Director"). The directors in the preceding clause (i) (the "TPI DIRECTORS") and
in the preceding clause (ii) (the "THE PCA DIRECTORS") are sometimes
collectively referred to as the "TPI/PCA DIRECTORS." TPI and PCA, as the holders
of the Junior Preferred Stock and thus entitled to elect the CEO Director,
shall: (x) at each election of directors (or filling of a vacancy with respect
to the CEO Director), elect the individual then serving as the Chief Executive
Officer of Newco as the CEO Director; and (y) remove the CEO Director if the CEO
Director ceases to serve as the Chief Executive Officer of the Company. The size
and composition of the board of directors or similar governing body of each
Subsidiary of Newco (each, a "SUBSIDIARY BOARD") and the manner in which the
initial members and any subsequent members (including any subsequent member
selected or appointed to fill a vacancy) of any such Subsidiary Board will be
the same as that of the Board. Anything to the contrary contained herein
notwithstanding, the rights of each of TPI and PCA to designate directors as
provided herein shall not be assignable (by operation of law, the transfer of
Shares or otherwise) without the prior written consent of the other; provided,
however, that each of TPI and PCA shall be entitled to assign its rights to
designate directors as provided herein to one of its Affiliates that is (or
becomes) a Stockholder without the prior written consent of the other. If
directed by PCA, a representative of J.P. Morgan & Co. shall be entitled to
attend meetings of (and receive information provided to the directors of) the
Board and each Subsidiary Board; provided, however, that such representative
shall not be or have any rights of a director of the Board or any Subsidiary
Board.

                  3.4 TERM; REMOVAL; VACANCIES. The members of the Board or any
Subsidiary Board other than the CEO Director shall hold office at the pleasure
of the Stockholder which designated them. Any such Stockholder may at any time,
by written notice to the other Stockholder and Newco, remove (with or without
cause) any member of the Board or any Subsidiary Board designated by such
Stockholder other than the CEO Director. Subject to applicable Law, no member of
the Board or any Subsidiary Board may be removed except by written request by
the Stockholder that designated the same. In the event a vacancy occurs on the
Board (or a Subsidiary Board) for any reason, the vacancy will be filled by the
written designation of the Stockholder entitled to designate the director
creating the vacancy.

                  3.5 NOTICE; QUORUM. Meetings of the Board and any Subsidiary
Board may be called upon three days' prior written notice to all directors
stating the purpose or purposes thereof. Such notice shall be effective upon
receipt, in the case of personal delivery or facsimile transmission, 


                                      -7-

<PAGE>   9

and five Business Days after deposit with the U.S. Postal Service, postage
prepaid, if mailed. The presence in person of three of the five TPI/PCA
Directors shall constitute a quorum for the transaction of business at any
special, annual or regular meeting of the Board or any Subsidiary Board. Each
Stockholder shall use its reasonable efforts to ensure that a quorum is present
at any duly convened meeting of the Board or any Subsidiary Board and each of
TPI and PCA may designate by written notice to the other an alternate
representative to act in the absence of any of its designates at any such
meeting. If at any meeting of the Board or any Subsidiary Board a quorum is not
present, a majority of the directors present may, without further notice,
adjourn the meeting from time to time until a quorum is obtained.

                  3.6 VOTING. Each member of the Board and each Subsidiary Board
shall be entitled to cast one vote on each matter considered by such Board and
Subsidiary Board, respectively; provided, however, that in the event that a vote
would result in a 3-3 tie with respect to a matter, the CEO Director shall not
be entitled to vote with respect to such matter (the Board and each Subsidiary
Board shall poll its members prior to any vote to effectuate the purposes of
this sentence). Except as otherwise expressly provided by this Agreement, the
act of a majority of the members of the Board and each Subsidiary Board present
at any meeting at which a quorum is present shall constitute an act of the Board
or Subsidiary Board, as applicable. Notwithstanding anything to the contrary
contained herein: (i) the following matters shall require, in addition to any
other vote required by applicable law, the affirmative vote of at least four of
the five TPI/PCA Directors; (ii) Newco shall not directly or indirectly take,
and shall not permit any of its Subsidiaries to directly or indirectly take, any
of the following actions without first obtaining such approval; and (iii) PCA
shall not cause or, to the extent reasonably within PCA's control, permit Newco

         Transfer; or (3) cause such governing documents, taken as a whole, to

shares for such issuances as contemplated in the Contribution Agreement.

                  TPI hereby covenants and agrees, as more fully described in

agreement in the preceding sentence: (i) shall relate only to matters, the
approval of which TPI determines in good faith are in the best interests of TPI

Exchange Act with respect to Shares: (i) Newco shall use commercially reasonable
efforts to effect a stock split, stock dividend or stock combination which, in
the opinion of the managing underwriter for the Public Offering or TPI's

agrees to vote all of its respective Shares and any other Voting Stock over
which it posses direct or indirect voting power in order to cause such stock
split, dividend or combination to be effected consistent with the provisions of

the preparation of financial statements required by applicable Law in accordance
with GAAP. Each Stockholder who, together with its Affiliates, owns 17-1/2% or
more of the outstanding common equity of Newco (a "17-1/2% Stockholder") and its
respective authorized representatives shall have the right, at all reasonable
times and upon reasonable advance written notice to Newco, to have access to,

statements of income, stockholders' equity and cash flows for such fiscal year),
in each case audited and certified by the CPA Firm. Such annual and interim

17-1/2% Stockholders in the preparation of such 17-1/2% Stockholder's own
financial statements. Such annual and interim financial statements shall be
prepared in accordance with GAAP, shall be true and accurate in all material
respects and shall present fairly the financial position and results of
operations of Newco.

Financial Statements in connection with TPI's and/or its Affiliates filings made
with the Securities and Exchange Commission and, subject to such auditor's 
normal procedures, in private or public offerings of securities of TPI and/or 
its Affiliates as may be 

                                      -12-
<PAGE>   14

reasonably requested by TPI. In addition, Newco will use commercially reasonable

                  5.2 SALE OF TIMBERLANDS. Newco, TPI and PCA hereby acknowledge
that it is their mutual intention to effect a sale for cash of the timberlands

soon as practicable following the Closing Date. If and to the extent the net
proceeds from any such sale are distributed to the holders of the Common Stock,
such distribution shall be on a pro-rata basis among such holders.

                                   ARTICLE VI
                               TRANSFER OF SHARES

                  6.1 GENERAL. No Stockholder will directly or indirectly sell,
assign, pledge, encumber, hypothecate, dispose of or otherwise transfer
("TRANSFER") any Shares or interest in any Shares, agree to any such Transfer or
permit any such interest to be subject to Transfer, directly or indirectly, by
merger or other operation of law, agreement or otherwise, except pursuant to and
in compliance with the provisions of this ARTICLE VI. Any purported Transfer in
any other manner, unless otherwise expressly permitted by this ARTICLE VI, shall
be null and void, and shall not be recognized or given effect by Newco or any
Stockholder. Any other provision of this Agreement, including, without
limitation, in this Article VI, to the contrary notwithstanding (except pursuant
to Section 8.1), neither TPI nor PCA shall Transfer any Shares of the Junior
Preferred Stock prior to the termination of this Agreement.

                  6.2 TRANSFERS BY TPI HOLDERS.

                  (a) PERMITTED TRANSFERS. A TPI Holder may at any time, without
the consent of any other Stockholder, Transfer any or all of its Shares or
interests in Shares to any Affiliate or third Person or Persons or pursuant to a
Public Sale, subject to the remaining provisions of this SECTION 6.2; provided,
however, that, except in the case of a Public Sale, TPI shall not Transfer any
Shares to any other Person then engaged, directly or indirectly, in a business
within the Business Scope with annual revenues from such business in excess of
$100 million without PCA's prior written consent. The foregoing consent right
shall not be assignable by PCA or inure to the benefit of any transferee,
successor or assign of PCA, except for an Affiliate of PCA who is (or becomes) a
Stockholder. Notwithstanding the foregoing and except in the case of a Public
Sale or sale to directors, officers or employees of Newco pursuant to the
Management Buy-In, any Transfer of Shares by a TPI Holder shall be null and void
and Newco shall refuse to recognize such Transfer 


                                      -13-
<PAGE>   15

unless the transferee executes and delivers to each party hereto an agreement (a
"TPI JOINDER AGREEMENT"): (i) acknowledging that all Shares or interests in any
Shares so transferred are and shall remain subject to this Agreement; and (ii)
agreeing to be bound hereby. Upon execution of a TPI Joinder Agreement, except
as otherwise expressly provided herein and except for any right hereunder to
consent to any action or proposed action (including, without limitation, any
proposed Transfer of Shares), the rights of the transferring TPI Holder
hereunder with respect to the Shares transferred shall be assigned to such
transferree. Any TPI Holder shall notify the other parties of any intended
Transfer of Shares or interests in Shares pursuant to this SECTION 6.2 (other
than pursuant to an Exempt Sale), giving the name and address of the intended
transferee; provided, however, that no otherwise valid Transfer shall be
rendered invalid solely as a result of a failure to give notice hereunder.
Transferees of a TPI Holder shall assume all obligations of the transferring TPI
Holder hereunder, but, except with respect to an Affiliate of TPI, shall not be
entitled to any rights of a TPI Holder.

                 6.3  TRANSFERS BY PCA HOLDERS.

                  (a) PERMITTED TRANSFERS. A PCA Holder may at any time, without
the consent of any other Stockholder, (i) Transfer any or all of its Shares to
an Affiliate of PCA, (ii) Transfer any or all its Shares pursuant to an Exempt
Sale, or (iii) sell any or all of its Shares to any other third Person or
Persons or pursuant to a Public Sale or otherwise Transfer Shares, subject to
the remaining provisions of this SECTION 6.3. The foregoing consent right shall
not be assignable by TPI or inure to the benefit of any transferee, successor or
assign of TPI, except for an Affiliate of TPI who is (or becomes) a Stockholder.
Notwithstanding the foregoing and except in the case of a Public Sale or sale to
directors, officers or employees of Newco pursuant to the Management Buy-In, any
Transfer of Shares by an PCA Holder shall be null and void and Newco shall
refuse to recognize such Transfer unless the transferee executes and delivers to
each party hereto an agreement (an "PCA JOINDER AGREEMENT"): (i) acknowledging
that all Shares or interests in any Shares so transferred are and shall remain
subject to this Agreement; and (ii) agreeing to be bound hereby. Upon execution
of an PCA Joinder Agreement, except as otherwise expressly provided herein and
except for any right hereunder to consent to any action or proposed action
(including, without limitation, any proposed Transfer of Shares), the rights of
the transferring PCA Holder hereunder with respect to the Shares transferred
shall be assigned to such transferee. Any PCA Holder shall notify the other
parties of any intended Transfer of Shares or interests in Shares pursuant to
this SECTION 6.3 (other than an Exempt Sale), giving the name and address of the
intended transferee; provided, however, that no otherwise valid Transfer shall
be rendered invalid solely as a result of a failure to give notice hereunder.

                  (b) TAG-ALONG RIGHTS. TPI and its Affiliates shall have
tag-along rights as provided in this SECTION 6.3(b):

                  (i) In the event any PCA Holder desires to sell all or any
part of any class or series of its Shares to a third Person (other than pursuant
to an Exempt Sale), it shall provide prior written notice (the "SALE NOTICE") to
TPI setting forth in reasonable detail the terms and conditions on which the
proposed sale is to be made and identifying the proposed purchaser. TPI shall
have the option (the "TAG-ALONG OPTION") to sell any or all of its Shares of the
same class and series to 


                                      -14-
<PAGE>   16

the proposed purchaser on the terms and conditions set forth in such Sale Notice
subject to the provisions set forth in this Section 6.3(b). TPI shall exercise
its Tag-Along Option by giving written notice to PCA within ten Business Days
following its receipt of the Sale Notice, which notice shall specify the number
of Shares of the same class and series as to which TPI is exercising its
Tag-Along Right (the "SPECIFIED SHARES"). In the event TPI exercises its
Tag-Along Option with respect to any Sale Notice: (A) if such exercise is within
14 months after the Closing Date, the PCA Holder shall not be entitled to sell
any of its Shares unless and until the prospective purchasers or PCA has
purchased all of the Specified Shares; and (B) if such exercise is more than 14
months after the Closing Date, TPI shall be entitled to sell its pro rata share
(based on the number of Shares proposed to be sold by the PCA Holder and TPI,
respectively) of the Shares proposed to be sold by the PCA Holder in the Sale
Notice, in each case on terms and conditions no less favorable than specified in
the Sale Notice or otherwise applicable to the sale to such prospective
purchasers by the PCA Holder. In the event TPI does not exercise its Tag-Along
Option with respect to any Sale Notice, the PCA Holder shall be entitled to sell
all or any part of its Shares as specified in the Sale Notice to the prospective
purchaser specified in the Sale Notice on the terms and conditions set forth in
the Sale Notice (subject to the provisions of the third sentence of SECTION
6.3(a) hereof).

                  (ii) Notwithstanding SUBSECTION 6.3(b)(i) above, with respect
to sales by a PCA Holder of any part of any class or series of its Shares to a
third Person (other than pursuant to an Exempt Sale) prior to the expiration of
the six-month period beginning on the Closing Date at a per share price which
does not exceed the per share price paid (excluding any interest for the
carrying cost of such Share) by such PCA Holder for such Shares pursuant to the
Contribution Agreement:

                  (A)  TPI and its Affiliates shall not have a Tag-Along
                       Option during such six-month period for (i) sales of
                       Shares (other than PIK Preferred) in the aggregate
                       amount of $40 million; and (ii) the sale of 9.3% of
                       the number of Shares of PIK Preferred issued at
                       Closing ("EXCLUDED TAG-ALONG SALES); and

                  (B)  TPI shall have a Tag-Along Option on a pro-rata basis
                       (i.e., on the same basis applicable 14 months after
                       the Closing Date as provided in SUBSECTION 6.3(b)(i)
                       above) with respect to such sales of Shares by PCA
                       Holders during such six-month period in excess of the
                       Excluded Tag Along Sales up to an aggregate amount of
                       consideration for such additional sales of $100
                       million (the "INITIAL PERIOD PRO-RATA TAG-ALONG").

The provisions of this SUBSECTION 6.3(b)(ii) shall terminate upon the expiration
of the six-month period beginning on the Closing Date.

                  (iii) Notwithstanding anything in this Agreement to the
contrary, the rights under this SECTION 6.3(b) shall be exclusive to TPI and its

<PAGE>   17


                  (a) DRAG-ALONG SALE. If a sale of all or substantially all of
Newco's assets determined on a consolidated basis or a sale of all or
substantially all of Newco's outstanding capital stock (whether by merger,
recapitalization, consolidation, reorganization, combination or otherwise) to
any Independent Third Party or group of Independent Third Parties is approved by
the Board or the holders of a majority of the Shares of Common Stock held by the
PCA Holders (a "DRAG-ALONG SALE"), each Stockholder will consent to raise no
objections against such Drag-Along Sale on the terms and subject to the
conditions set forth in the remaining provisions of this SECTION 6.4.

                  (b) DRAG-ALONG NOTICE. A notice regarding any Drag-Along Sale
(a "DRAG-ALONG NOTICE") shall be delivered within two Business Days following
approval of any Drag-Along Sale by Newco or the PCA Holders to each Stockholder.
The Drag-Along Notice shall include a copy of a bona fide offer from the
intended buyer, which shall set forth the principal terms of the Drag-Along
Sale, including the name and address of the intended buyer.

                  (c) DRAG-ALONG SALE OBLIGATIONS. In connection with any
Drag-Along Sale, the Stockholders shall, and shall elect directors who shall,
take all necessary or desirable actions in connection with the consummation of
the Drag-Along Sale. If the Drag-Along Sale is structured as: (i) a merger or
consolidation, each Stockholder shall waive any dissenters rights, appraisal
rights or similar rights in connection with such merger or consolidation; (ii) a
sale of stock, each Stockholder shall agree to sell all of its Shares and rights
to acquire Shares on the terms and conditions so approved; or (iii) a sale or
assets, each Stockholder shall vote in favor of such sale and any subsequent
liquidation of Newco or other distribution of the proceeds therefrom. Each
Stockholder shall take all necessary or desirable actions in connection with the
consummation of the Drag-Along Sale reasonably requested by PCA or Newco, and
each Stockholder shall be obligated to agree on a pro rata, several (and not
joint) basis (based on the share of the aggregate proceeds paid in such
Drag-Along Sale) to any indemnification obligations that the PCA Holders agree
to provide in connection with such Drag-Along Sale (other than any such
obligations that relate specifically to a particular holder of Shares such as
indemnification with respect to representations and warranties given by a holder
regarding such holder's title to and ownership of Shares).

                  (d) CONDITIONS TO DRAG-ALONG SALE OBLIGATIONS. The obligations
of each Stockholder with respect to a Drag-Along Sale are subject to the
satisfaction of the following conditions: (i) the consideration to be received
by the Stockholders with respect to the Drag-Along Sale shall consist only of
cash, publicly-traded securities, or a combination of cash and publicly-traded
Securities; (ii) if any holders of a class or series of Shares are given an
option as to the form and amount of consideration to be received, each holder of
such class or series of Shares will be given the same option; (iii) each holder
of then currently exercisable rights to acquire shares of a class or series of
Shares will be given an opportunity to exercise such rights prior to the
consummation of the Drag-Along Sale and participate in such sale as holders of
such class or series of Shares; and (iv) each Stockholder shall be entitled to
receive consideration per each Share in connection with the Drag-Along Sale at
least equivalent to the consideration received per each Share of the same class
and series by any PCA Holder in connection with the Drag-Along Sale.

                  (e) EXPENSES. Each Stockholder will bear its pro-rata share



                                      -16-
<PAGE>   18

(based on the share of the aggregate proceeds paid in such Drag-Along Sale) of
the costs of any sale of Shares pursuant to a Drag-Along Sale to the extent such
costs are incurred for the benefit of all holders of Common Stock and are not
otherwise paid by Newco or the acquiring party. For purposes of this SECTION
6.4(e), costs incurred in exercising reasonable efforts to take all necessary
actions in connection with the consummation of a Drag-Along Sale in accordance
with this SECTION 6.4 shall be deemed to be for the benefit of all holders of
Common Stock. Costs incurred by Stockholders on their own behalf will not be
considered costs of the transaction hereunder.

                  (f) EXCEPTION TO DRAG-ALONG. Notwithstanding anything to the
contrary contained in this SECTION 6.4, no Stockholder shall have any obligation
under this SECTION 6.4 with respect to a Drag-Along Sale if the Drag-Along
Notice with respect to the Drag-Along Sale is received by TPI after the holders
of TPI Registrable Securities have requested a Demand Registration and for a
period thereafter ending on the date following consummation of the sale of all
Shares subject to such Demand Registration unless, in the opinion of the
managing underwriter for such Demand Registration, the per Share consideration
payable pursuant to the Drag-Along Sale exceeds the net proceeds per Share
expected to be received by selling stockholders pursuant to the Demand
Registration.

                  6.5 INDIRECT TRANSFERS OF INTERESTS. Any Transfer of equity
securities of PCA which results in the group of Persons holding such equity
securities immediately following the transactions contemplated in the
Contribution Agreement from ceasing to beneficially own, as a group, directly or
indirectly, 50.1% or more of the equity securities of PCA or enough voting
equity of PCA to be able to cause a majority of the board of managers (or
equivalent governing body or members) to be elected shall be deemed to be a
Transfer of Shares hereunder and any such Transfer shall be subject to the
provisions of this ARTICLE VI as if PCA had directly transferred Shares.

                  6.6 LEGENDS. A copy of this Agreement shall be filed with the 
Secretary of Newco and kept with the records of Newco. Each of the Stockholders
hereby agrees that each outstanding  certificate representing Shares shall bear 
a conspicuous legend reading substantially as follows:

         "The securities represented by this Certificate have not been
         registered under the Securities Act of 1933 or the applicable state and
         other securities laws and may not be sold, pledged, hypothecated,
         encumbered, disposed of or otherwise transferred without compliance
         with the Securities Act of 1933 or any exemption thereunder and
         applicable state and other securities laws. The securities represented
         by this Certificate are subject to the restrictions on transfer and
         other provisions of a Stockholders Agreement dated as of April 12,
         1999, (as amended from time to time, the "Agreement") by and among
         Packing Corporation of America (the "Company") and certain of its
         stockholders, and may not be sold, pledged, hypothecated, encumbered,
         disposed of or otherwise transferred except in accordance therewith. A
         copy of the Agreement is on file at the principal executive offices of
         the Company.

                                  ARTICLE VII
                        RIGHTS ON NEW SECURITY ISSUANCE

                  7.1 PREEMPTIVE RIGHTS. Newco hereby grants to each Stockholder
the irrevocable and exclusive first option (the "FIRST OPTION") to purchase all
or part of its Pro Rata Portion of any New Securities which Newco may, from time
to time after the date of this Agreement, propose to issue and sell or otherwise
transfer.

                  7.2 NOTICES WITH RESPECT TO PROPOSED ISSUANCE OF NEW 
SECURITIES. In the event Newco proposes to undertake an issuance or other 
transfer of New Securities, it shall give each Stockholder entitled to a First 
Option pursuant to this ARTICLE VII written notice (the "COMPANY NOTICE") of its
intention, describing in detail the type of New Securities, the price and the 
terms upon which Newco proposes to issue or otherwise transfer such New 
Securities. Each such Stockholder shall have 10 Business Days from the date of 
receipt of any such Company Notice to agree to purchase, pursuant to the 
exercise of the First Option, up to such Stockholder's Pro Rata Portion of each 
type and class and series of such New Securities (i.e., the same strips) for the
price and upon the terms and conditions specified in the Company Notice by 
giving written notice to Newco and stating therein the quantity of New 
Securities to be purchased.

                  7.3 COMPANY'S RIGHT TO COMPLETE PROPOSED SALE OF NEW 
SECURITIES TO THE EXTENT PREEMPTIVE RIGHTS ARE NOT EXERCISED. In the event the 
Stockholders fail to exercise a preemptive right with respect to any New 
Securities within The periods specified in SECTION 7.2, Newco shall have 90 days
thereafter to sell or enter into an agreement (pursuant to which the sale of 
such New Securities shall be closed, if at all, within 45 days from the date of 
said agreement) to sell the New Securities not elected to be purchased by the
Stockholders at the price and upon terms not substantially more favorable to the
prospective purchasers of such securities than those specified in Newco Notice.
In the event Newco has not sold the New Securities or entered into an agreement
to sell the New Securities within said 90-day period. Newco shall not thereafter
issue or sell or otherwise transfer such New Securities without first offering
such securities to the Stockholders in the manner provided in this ARTICLE VII.

                  7.4 CLOSING OF PURCHASE. If a Stockholder elects to purchase 
up to its Pro Rata Portion of any New Securities set forth in any Company 
Notice, such purchase shall be consummated at such time and at such location 
selected by Newco upon reasonable advance notice. At the consummation of any 
purchase and sale of New Securities pursuant to this ARTICLE VII: (i) Newco 
shall issue or otherwise transfer to the Stockholder the certificates evidencing
the New Securities being purchased, together with such other documents or 
instruments reasonably required by counsel for the Stockholder to consummate 
such purchase and sale; (ii) the Stockholder will deliver the cash consideration
payable by wire transfer of immediately available funds to an account or 
accounts designated in writing by Newco (such designation to be made no later 
than two Business Days prior to the date of such consummation); (iii) Newco 
shall deliver to the Stockholder a written representation that the New 
Securities are being purchased and sold free and clear of any and all 
Encumbrances; and (iv) the Stockholder shall deliver to Newco such written 
investment representations as may reasonably be required by counsel to Newco for
securities Laws purposes and

                                      -18-
<PAGE>   20


all other applicable representations and warranties as other purchasers of New
Securities. Notwithstanding the foregoing, any purchase of New Securities 
pursuant to this Article VII shall be on the same terms and conditions as set
forth in the Company Notice.

                                  ARTICLE VIII
                                      TERM

                  8.1 TERM. Subject to the next sentence, unless earlier
terminated by mutual agreement of TPI and PCA, this Agreement shall terminate
upon the earliest to occur of: (i) the complete liquidation or dissolution of
Newco or its Subsidiaries; (ii) a Public Offering; (iii) such date as TPI and
its Affiliates first hold less than 17-1/2% of Newco's outstanding Common Stock
or; (iv) the acquisition of all or substantially all of the stock or assets of
TPI (whether by stock sale, asset sale, merger, consolidation, combination or
otherwise) by a Person engaged, directly or indirectly, in a business within the
Business Scope with annual revenues from such business in excess of $100
million; provided; however, that in the case of termination pursuant to clause
(iv), TPI (or its successor in interest) shall (unless or until this Agreement
is terminated pursuant to clauses (i)-(iii)) have the right at each election of
directors to designate as the two TPI Directors of Newco and each Subsidiary who
are not directors, officers, employees or affiliates of such Person and are
approved by PCA, such approval not to be unreasonably withheld; provided,
further, that in case of any termination pursuant to this SECTION 8.1, unless
otherwise determined by PCA, this Agreement shall nevertheless remain in full
force and effect with respect to the drag-along provisions set forth in SECTION
6.4 and all related definitions and provisions to the extent necessary or
desirable to give full force and effect to SECTION 6.4. The rights of each of
TPI and PCA to terminate this Agreement by mutual agreement and the right of PCA
to terminate this Agreement with respect to the drag-along provisions of SECTION
6.4 are not assignable by TPI or PCA, and shall not inure to the benefit of any
transferee, successor or assign of TPI or TPI, other than to an Affiliate of
such party who is (or becomes) a Stockholder, without the prior written consent
of the other. Upon the termination of this Agreement pursuant to clauses
(i)-(iv) (regardless of whether certain provisions of this Agreement survive
such termination), TPI shall sell the 45 shares of Junior Preferred Stock held
by it to PCA for the fair market value thereof, as determined by the auditors of
Newco.


                                   ARTICLE IX

                                    on the books and records
                                    of Newco

or to such other address as any party hereto may, from time to time, designate
in a written notice given in like manner. All notices and other communications
hereunder shall be effective: (i) the day of delivery when delivered by hand,
facsimile or overnight courier; and (ii) three Business Days from the date
deposited in the mail in the manner specified above.

                  9.2 AMENDMENT; WAIVER. Any provision of this Agreement may be
amended or waived if, and only if, such amendment or waiver is in writing and
signed: (i) in the case of an amendment, by: (A) Newco; (B) Stockholders holding
a majority of the Shares of Common Stock held by the TPI Holders; (C)
Stockholders holding a majority of the Shares of Common Stock held by PCA
Holders; and (D) by each of PCA and TPI (in each case only so long as such
Person or any of its Affiliates is a Stockholder); or (ii) in the case of a
waiver, by the party against whom the waiver is to be effective. The rights of
TPI and PCA to consent to a amendment to this Agreement shall not be assignable
by TPI or PCA and shall not inure to the benefit of any transferee, successor or
assign of TPI or PCA, other than to an Affiliate of such party who is a (or in
connection therewith, becomes) Stockholder, without the prior written consent of
the other. No failure or delay by any party in exercising any right, power or
privilege hereunder 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. Except as otherwise provided
herein, the rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law.

                  9.3 ASSIGNMENT. Except as otherwise expressly provided herein,
no party to this Agreement may assign any of its rights or obligations under 
this Agreement without the prior written consent of the other parties hereto.

                  9.4 ENTIRE AGREEMENT. This Agreement (including the exhibits 
hereto), contains the entire agreement among the parties hereto with respect to 
the subject matter hereof and supersedes all prior agreements and 
understandings, oral or written, with respect to such matters.

                  9.5 PUBLIC DISCLOSURE. Each of the parties hereby agrees that,
except as may be required to comply with the requirements of any applicable Laws
or the rules and regulations of any stock exchange upon which its securities (or
the securities of one of its Affiliates) are traded, it shall 


                                      -21-
<PAGE>   23

not make or permit to be made any press release or similar public announcement
or communication concerning the execution or performance of this Agreement
unless specifically approved in advance by all parties hereto. In the event,
however, that legal counsel for any party is of the opinion that a press release
or similar public announcement or communication is required by Law or by the
rules and regulations of any stock exchange on which such party's securities (or
the securities of one of such party's Affiliates) are traded, then such party
may issue a public announcement limited solely to that which legal counsel for
such party advises is required under such Law or such rules and regulations (and
the party making any such announcement shall provide a copy thereof to the other
party for review before issuing such announcement).

                  9.6 PARTIES IN INTEREST. This Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective
successors and permitted assigns. Nothing in this Agreement, express or implied,
is intended to confer upon any Person other than Newco, TPI, PCA or their
respective successors or permitted assigns, any rights or remedies under or by
reason of this Agreement.

                  9.7 GOVERNING LAW; SUBMISSION TO JURISDICTION; SELECTION OF
FORUM. This Agreement shall be governed by, and construed in accordance with,
the laws of the State of Delaware, without giving effect to its principles of
conflicts of laws. Each party hereto agrees that it shall bring any action or
proceeding in respect of any claim arising out of or related to this agreement
or the transactions contained in or contemplated by this agreement, whether in
tort or contract or at law or in equity, exclusively in any United States
federal court or any state court located in the State of Illinois (the "CHOSEN
COURTS") and: (i) irrevocably submits to the exclusive jurisdiction of the
Chosen Courts; (ii) waives any objection to laying venue in any such action or
proceeding in the Chosen Courts; (iii) waives any objection that the Chosen
Courts are an inconvenient forum or do not have jurisdiction over any party
hereto; and (iv) agrees that service of process upon such party in any such
action or proceeding shall be effective if notice is given in accordance with
SECTION 9.1 of this Agreement.

                  9.8 COUNTERPARTS. This Agreement may be executed in one or 
more counterparts, each of which shall be deemed an original, and all of which 
shall constitute one and the same Agreement.

                  9.9 SEVERABILITY. The provisions of this Agreement shall be
deemed severable and the invalidity or unenforceability of any provision shall
not affect the validity or enforceability of the other provisions hereof or
thereof. If any provision of this Agreement, or the application thereof to any
Person or any circumstance, is invalid or unenforceable: (a) a suitable and
equitable provision shall be substituted therefor in order to carry out, so far
as may be valid and enforceable, the intent and purpose of such invalid or
unenforceable provision; and (b) the remainder of this Agreement and the
application of such provision to other Persons or circumstances shall not be
affected by such invalidity or unenforceability, nor shall such invalidity or
unenforceability affect the validity or enforceability of such provision, or the
application thereof, in any other jurisdiction.

                 9.10 HEADINGS. The heading references and the table of contents
herein are for convenience purposes only, do not constitute a part of this  
Agreement and shall not be deemed to limit or affect any of the provisions 
hereof.

                 9.11 EQUITABLE RELIEF. Each party acknowledges that money 
damages would be inadequate to protect against any actual or threatened breach 
of this Agreement by any party and that each party shall be entitled to 
equitable relief, including specific performance and/or injunction, without 
posting bond or other security in order to enforce or prevent any violations of 
the provisions of this Agreement.

                 9.12 NO PARTNERSHIP. This Agreement shall not constitute an
appointment of any party as the agent of any other party, nor shall any party
have any right or authority to assume, create or incur in any manner any
obligation or other liability of any kind, express or implied, against, in the
name or on behalf of, any other party. Nothing herein or in the transactions
contemplated by this Agreement shall be construed as, or deemed to be, the
formation of a partnership by or among the parties hereto.

                          REGISTRATION RIGHTS AGREEMENT

                  This Registration Rights Agreement ("AGREEMENT") is made as of
this 12th day of April, 1999 by and among Tenneco Packaging Inc., a Delaware
corporation ("TPI"), PCA Holdings LLC, a Delaware limited liability company
("PCA"), and Packaging Corporation of America, a Delaware corporation ("NEWCO").

                              PRELIMINARY RECITALS

                  1.       TPI, PCA and Newco are parties to that certain
Contribution Agreement, dated as of January 25, 1999, as amended (the
"CONTRIBUTION AGREEMENT"), relating to the organization, ownership and
management of Newco and certain other matters.

                  2.       As an inducement to TPI and PCA to enter into and
consummate the transactions contemplated by the Contribution Agreement, Newco
has agreed to provide certain registration rights to TPI and PCA and transferees
(to the extent provided herein) of their equity securities of Newco as provided
herein.

                  NOW, THEREFORE, the parties hereto AGREE as follows:

                  1.       CERTAIN DEFINITIONS.

                  "COMMON STOCK" means the common stock, par value $.01 per 
share, of Newco.

                  "PERSON" means an individual, a partnership, a corporation, an
association, a joint stock company, a trust, a joint venture, a limited
liability company or other unincorporated organization, and a governmental
entity or any department, agency or political subdivision thereof.

                  "PIK SECURITIES" means the preferred stock of Newco with a
pay-in-kind feature, as described in the Commitment Letters (as such term is
defined in the Contribution Agreement).

                  "REGISTRABLE SECURITIES" means, as of any date: (i) Common
Stock and PIK Securities issued pursuant to the Contribution Agreement to TPI,
PCA or any of their respective Affiliates on the date hereof; and (ii) any
Common Stock or PIK Securities issued or issuable with respect to the Common
Stock or PIK Securities in the preceding clause (i) by way of or in connection
with a stock dividend, stock split, combination of shares, share subdivision,
share exchange, recapitalization, merger, consolidation or other reorganization
or transaction (including without limitation any PIK Securities issued pursuant
to the terms of PIK Securities). As of any date, Registrable Securities owned by
TPI or any of its Affiliates are sometimes referred to herein as "TPI
REGISTRABLE SECURITIES." As of any date, Registrable Securities owned by PCA, by
its members which are members of PCA as of the date hereof or by any of their
Affiliates are sometimes referred to herein as "PCA REGISTRABLE SECURITIES." As
of any date, Registrable Securities owned by any direct or indirect transferee
of TPI (other than an Affiliate of TPI) or by any direct or indirect transferee

any particular
<PAGE>   2
Registrable Securities, such securities will cease to be Registrable Securities
when they have been distributed to the public pursuant to a offering registered
under the Securities Act of 1933, as amended from time to time (the "SECURITIES
ACT"), or distributed to the public in compliance with Rule 144 under the
Securities Act. For purposes of this Agreement, a Person will be deemed to be a
holder of Registrable Securities whenever such Person has the right to acquire
directly or indirectly such Registrable Securities (upon conversion or exercise
in connection with a transfer of securities or otherwise, but disregarding any
restrictions or limitations upon the exercise of such right), whether or not
such acquisition has actually been effected.

                  "REGISTRATION EXPENSES" means any and all expenses incident to
performance of, or compliance with any registration of securities pursuant to,
this Agreement, including, without limitation: (i) the fees, disbursements and
expenses of Newco's counsel and accountants; (ii) the fees, disbursements and
expenses of one or more firms, as applicable pursuant to the terms of this
Agreement, selected as counsel for the holders of the Registrable Securities in
connection with the registration of the securities to be disposed of; (iii) all
expenses, including registration and filing fees, in connection with the
preparation, printing, filing and distribution of the registration statement,
any preliminary prospectus or final prospectus, term sheets and any other
offering documents, and amendments and supplements thereto, and the mailing and
delivering of copies thereof to any underwriters and dealers; (iv) the cost of
printing or producing any underwriting agreements and blue sky or legal
investment memoranda, and any other documents in connection with the offering,
sale or delivery of the securities to be disposed of; (v) all expenses in
connection with the qualification of the securities to be disposed of for
offering and sale under state securities laws, including the fees, disbursements
and expenses of counsel for the underwriters or the holders of the Registrable
Securities in connection with such qualification and in connection with any blue
sky and legal investment surveys; (vi) the filing fees incident to securing any
required review by the National Association of Securities Dealers, Inc. of the
terms of the sale of the securities to be disposed of; (vii) transfer agents'
and registrars' fees and expenses and the fees and expenses of any other agent
or trustee appointed in connection with such offering; (viii) all security
engraving and security printing expenses; (ix) all fees, disbursements and
expenses payable in connection with the listing of the securities on any
securities exchange or automated interdealer quotation system and the rating of
such securities; (x) any other fees, disbursements and expenses of underwriters
customarily paid by the sellers of securities (excluding underwriting discounts
and commissions); (xi) all liability insurance expense; and (xii) other
out-of-pocket expenses of the holders of the Registrable Securities
participating in such registration. Notwithstanding the foregoing, each holder
of the Registrable Securities and Newco shall be responsible for its own
internal administrative and similar costs.

                  2.       DEMAND REGISTRATIONS.

                  (a)      GENERAL. At any time and from time to time, upon
written notice from either the holders of at least 75% of the TPI Registrable
Securities or the holders of at least 75% of the PCA Registrable Securities
requesting that Newco effect the registration under the Securities Act of any or
all the TPI Registrable Securities or the PCA Registrable Securities,
respectively, Newco shall effect the registration (under the Securities Act and
applicable state securities laws) of such securities (and other Registrable
Securities subject to Sections 2(c) and 2(d) below) in accordance with such
notice, Section 5 below and the other provisions of this Agreement. The notice
shall 

                                      -2-
<PAGE>   3
specify the approximate number of Registrable Securities to be registered and
the expected per share price range for the offering. A registration pursuant to
this Section 2 is sometimes referred to herein as a "DEMAND REGISTRATION."

                  (b)      LIMITATIONS ON DEMAND REGISTRATIONS; DEMAND
REGISTRATION FORMS AND EXPENSES. The holders of the TPI Registrable Securities,
on the one hand, and the holders of the PCA Registrable Securities, on the other
hand, each shall be entitled to separately request pursuant to this Section 2:

                           (i)     three (3) effected registrations on Form S-1
                                   or any similar or successor long form
                                   registration including, without limitation,
                                   Form A contemplated by the Securities and
                                   Exchange Commission ("SEC") in Release No.
                                   33-7606 dated October 15, 1998 (the
                                   "AIRCRAFT CARRIER RELEASE") ("LONG-FORM
                                   REGISTRATIONS") in which Newco shall pay all
                                   Registration Expenses;

                           (ii)    an unlimited number of registrations on Form
                                   S-2 or S-3 or any similar or successor short
                                   form registration including, without
                                   limitation, Form B contemplated by the SEC
                                   in the Aircraft Carrier Release ("SHORT-FORM
                                   REGISTRATIONS") in which Newco shall pay all
                                   Registration Expenses; and

                           (iii)   an unlimited number of Long-Form
                                   Registrations in which the holders of the
                                   Registrable Securities participating in such
                                   registration shall pay all Registration
                                   Expenses.

For purposes of clause (iii) above, each holder of securities included in
accordance with this Agreement in any registration pursuant to clause (iii)
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
will be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.
Newco shall pay and be solely responsible for Registration Expenses with respect
to registrations effected under clause (i) and (ii) above.

                  After Newco has become subject to the Securities Exchange Act
of 1934, as amended from time to time ("EXCHANGE ACT"), Newco will use its
reasonable best efforts to make Short-Form Registrations available for the sale
of Registrable Securities. Demand Registrations will be Short-Form Registrations
whenever Newco is permitted to use any applicable short form; provided, however,
that Newco shall nevertheless use a Long-Form Registration Statement in the
event that both: (i) the use of a Short-Form Registration Statement would limit
the offering to existing security holders, qualified institutional buyers or
other classes of offerees or would otherwise, in the opinion of the managing
underwriters, have an adverse effect on the offering under the Securities Act
and regulations thereunder as then in effect; and (ii) the holders of 90% of the
TPI Registrable Securities or PCA Registrable Securities, as the case may be,
initially requesting the Demand Registration direct in such request that Newco
utilize a Long-Form Registration Statement.

                                      -3-
<PAGE>   4
                  Notwithstanding any other provision of this Agreement to the
contrary, a registration requested hereunder shall not be deemed to have been
effected: (i) unless it has become and remains effective for the period
specified in Section 5(b); (ii) if after it has become effective such
registration is interfered with by any stop order, injunction or other order or
requirement of the Securities and Exchange Commission ("SEC") or other
governmental agency or court for any reason other than due solely to the fault
of the holders of the Registrable Securities participating therein and, as a
result thereof, the Registrable Securities requested to be registered cannot be
completely distributed in accordance with the plan of distribution set forth in
the registration statement; or (iii) if the conditions to closing specified in
any purchase agreement or underwriting agreement entered into in connection with
any such registration are not satisfied or waived other than due solely to the
fault of the holders of the Registrable Securities participating therein. In
addition, a Demand Registration initially requested by the holders of the TPI
Registrable Securities shall not be deemed to have been effected if the holders
of the TPI Registrable Securities are unable, as a result of the priority
provisions in Section 2(d) below, to sell at least 90% of the TPI Registrable
Securities initially requested to be included in such registration. Similarly, a
Demand Registration initially requested by the holders of the PCA Registrable
Securities shall not be deemed to have been effected if the holders of the PCA
Registrable Securities are unable, as a result of the priority provisions in
Section 2(d) below, to sell at least 90% of the PCA Registrable Securities
initially requested to be included in such registration.

                  (c)      NOTICE TO OTHER HOLDERS; SELECTION OF UNDERWRITER
AND HOLDER'S COUNSEL. Within five (5) days after receipt of a request for a
Demand Registration, Newco will give prompt written notice (in any event within
five (5) days after its receipt of notice of any exercise of Demand Registration
rights under this Agreement) of such request to all other holders of Registrable
Securities, and subject to Section 2(d) below, will include within such
registration all Registrable Securities with respect to which Newco has received
written requests for inclusion therein within fifteen (15) days after receipt of
Newco's notice. The holders of a majority of the TPI Registrable Securities or
PCA Registrable Securities, as applicable, submitting the initial request (i.e.
excluding the holders submitting requests after Newco's notice) shall have the
right to select the investment bankers and managers for the offering, subject to
the approval of the other holders of the TPI Registrable Securities and PCA
Registerable Securities, if any, participating in such registration pursuant to
this Agreement, which approval shall not be unreasonably withheld.

                  Counsel for all holders of Registrable Securities in
connection with such registration shall be selected: (i) by the holders of a
majority of the TPI Registrable Securities, if holders of the TPI Registrable
Securities make the initial registration request; or (ii) by the holders of a
majority of the PCA Registrable Securities, if the holders of the PCA
Registrable Securities make the initial registration request; provided, however,
if the holders of a majority of the PCA Registrable Securities, on the one hand,
and a majority of the TPI Registrable Securities, on the other hand, reasonably
conclude, after consultation with the other, that such representation is likely
to result in a conflict of interest or materially adversely affect either
group's rights in connection with such registration, then the holders of a
majority of the PCA Registrable Securities and the holders of a majority of the
TPI Registrable Securities, respectively, shall each be entitled to select a
separate firm to represent them as counsel in connection with such registration.
The fees and expenses of such firm or firms acting as counsel for the holders of
the Registrable Securities shall be paid by 

                                      -4-

Newco.

                  (d)      PRIORITY ON DEMAND REGISTRATIONS. Newco shall not
include in any Demand Registration any securities which are not Registrable
Securities without the prior written consent of the holders of at least 90% of
the Registrable Securities included in such registration. If a Demand
Registration is an underwritten offering and the managing underwriters advise
Newco in writing that in their opinion the number of Registrable Securities and,
if permitted hereunder, other securities requested to be included in such
offering exceeds the number of Registrable Securities and other securities, if
any, which can be sold in an orderly manner in such offering within a price
range acceptable to the holders of a majority of the TPI Registrable Securities
or PCA Registrable Securities, as applicable, initially requesting registration,
Newco will include in such registration:

                           (A)     if requested by the holders of the TPI
                  Registrable Securities or by the holders of the PCA
                  Registrable Securities at any time during the 14-month period
                  commencing on the date hereof (the "SPECIAL PRIORITY PERIOD"),
                  only the number of Registrable Securities which such
                  underwriters advise in writing can be sold in such manner and
                  within such price range in the following order of priority:

                           (i)     first, the TPI Registrable Securities, if
                                   any, requested to be included therein,
                                   pro-rata among the holders of such TPI
                                   Registrable Securities on the basis of the
                                   number of shares requested to be included by
                                   each such holder;

                           (ii)    second, the PCA Registrable Securities, if
                                   any, requested to be included therein,
                                   pro-rata among the holders of such PCA
                                   Registrable Securities on the basis of the
                                   number of shares requested to be included by
                                   each such holder;

                           (iii)   third, the Transferee Registrable
                                   Securities, if any, requested to be included
                                   therein, pro-rata among the holders of such
                                   Transferee Registrable Securities on the
                                   basis of the number of shares requested to
                                   be included by each such holder; and

                           (iv)    fourth, any other securities requested to be
                                   included in such registration; and

                           (B)     if requested by the holders of the TPI
                  Registrable Securities or by the holders of the PCA
                  Registrable Securities at any time after the Special Priority
                  Period, only the number of Registrable Securities which such
                  underwriters advise in writing can be sold in such manner and
                  within such price range in the following order of priority:

                                      -5-
<PAGE>   6

                           (i)     first, the TPI Registrable Securities and
                                   the PCA Registrable Securities requested to
                                   be included therein, pro-rata among the
                                   holders of such Registrable Securities on
                                   the basis of the number of shares requested
                                   to be included by each such holder;

                           (ii)    second, the Transferee Registrable
                                   Securities, if any, requested to be included
                                   therein, pro-rata among the holders of such
                                   Transferee Registrable Securities on the
                                   basis of the number of shares requested to
                                   be included by each such holder; and

                           (iii)   third, any other securities requested to be
                                   included in such registration.

                  (e)      RESTRICTIONS ON DEMAND REGISTRATIONS. Newco will not
be obligated to effect any Demand Registration within 90 days after the
effective date of a previous Demand Registration or previous registration in
which holders of Registrable Securities were given piggyback rights pursuant to
Section 3 at an offering price acceptable to the holders of the Registrable
Securities and in which there was no reduction in the number of Registrable
Securities requested to be included. Additionally, Newco may postpone for up to
90 days (on not more than one occasion during any 12-month period) the filing or
the effectiveness of a registration statement for a Demand Registration if,
based on the advice of counsel, Newco reasonably determines that such Demand
Registration would likely have an adverse effect on any proposal or plan by
Newco to engage in any acquisition of assets (other than in the ordinary course
of business) or any merger, consolidation, tender offer or similar transaction;
provided, however, that in such event, the holders of Registrable Securities
initially requesting such Demand Registration will be entitled to withdraw such
request and, if such request is withdrawn, such Demand Registration will not
count as one of the permitted Demand Registrations hereunder and Newco will pay
all Registration Expenses in connection with such registration.

                  (f)       OTHER REGISTRATION RIGHTS. Newco will not register
for the benefit of any Person other than TPI, PCA or their respective direct or
indirect transferees, or grant to any such other Person the right to request
Newco to register or to participate in Piggyback Registrations with respect to,
any equity securities of Newco, or any securities convertible or exchangeable
into or exercisable for such securities, without the prior written consent of
both (i) TPI, as long as it or any of its Affiliates owns any TPI Registrable
Securities and (ii) PCA, as long as it or any of its Affiliates owns any PCA
Registrable Securities.

                  3.       PIGGYBACK REGISTRATIONS.

                  (a)      GENERAL; NOTICE TO HOLDERS. In addition to the
registration rights in Section 2 above, whenever Newco proposes to register any
of its securities under the Securities Act (other than pursuant to a Demand
Registration hereunder) and the registration form to be used may be used for the
registration of Registrable Securities, Newco will give prompt written notice
(in any event within five (5) days after its receipt of notice of any exercise
of demand registration rights other than under this Agreement) to all holders of

                                   included therein by the holders requesting

the holders of Registrable Securities to file a registration statement pursuant
to Section 2 above or if it has filed a Registration Statement pursuant to this

or abandoned, Newco will not file or cause to be effected any other registration
of any of its equity securities or securities convertible or exchangeable into
or exercisable for its equity securities under the Securities Act (except on
Form S-8 or any successor form), whether on its own behalf or at the request of
any holder or holders of such securities, until the expiration of the
effectiveness period required under Section 5(b) below.

                  (a)      AGREEMENT BY HOLDERS. Each holder of Registrable

any securities convertible into or exchangeable or exercisable for such
securities, during the seven days prior to and the 180-day period beginning on
the effective date of any underwritten Demand Registration or any underwritten
Piggyback Registration in which Registrable Securities are included (except as

affiliates not to effect or facilitate any public sale or distribution

Securities participating in such registration and the holders of a majority of
the PCA Registrable Securities participating in such registration otherwise
agree.

(i) such time as all of such Registrable Securities included therein have been
disposed of in accordance with the intended methods of disposition; and (ii) the
expiration of 180 days after such registration statement becomes effective;
provided, that such 180-day period shall be extended for such number of days
that equals the number of days elapsing from (x) the date the written notice

                  (d)      furnish to the holders of the Registrable Securities

Securities or such underwriter may reasonably request;

                  (e)      use its reasonable best efforts to register or
qualify all Registrable Securities covered by such registration statement under
the securities or blue sky laws of such jurisdictions as the holders of the
Registrable Securities included in such registration statement or any
underwriter of such Registrable Securities shall request, and use its reasonable
best efforts to obtain all appropriate registrations, permits and consents in
connection therewith, and do any and all other acts and things which may be
necessary or advisable to enable such holders of such Registrable Securities or
any such underwriter to consummate the disposition in such jurisdictions of its
Registrable Securities covered by such registration statement;

                  (f)      furnish to the holders of the Registrable Securities
included in such registration statement and to any underwriter of such
Registrable Securities: (i) an opinion of counsel for Newco addressed to the
holders of such Registrable Securities and dated the date of the closing under
the underwriting agreement (if any) (or if such offering is not underwritten,
dated the effective date of the registration statement); and (ii) a "cold
comfort" letter addressed to the holders of such Registrable Securities and
signed by the independent public accountants who have audited the financial
statements of Newco included in such registration statement, in each such case

statement (and the prospectus included therein) as are customarily covered in
opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities and such other
matters as the holders of such Securities may reasonably request and, in the
case of such accountants' letter, with respect to events subsequent to the date
of such financial statements;

                  (g)      as promptly as practicable, notify the holders of the
Registrable Securities included in such registration statement in writing: (i)
at any time when a prospectus relating to a registration statement hereunder is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact

                                      -11-
<PAGE>   12
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading; and (ii)
of any request by the SEC or any other regulatory body or other body having
jurisdiction for any amendment of or supplement to any registration statement or
other document relating to such offering, and in either such case, prepare and
furnish to the holders of such Registrable Securities a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
are made, not misleading;

                  (h)      cause all such Registrable Securities included in
such registration statement to be listed on each securities exchange on which
similar securities issued by Newco are then listed and, if not so listed, to be

of any offering of Registrable Securities pursuant to a registration hereunder
unlegended certificates representing ownership of the Registrable Securities
being sold in such denominations as shall be requested by the holders of the
Registrable Securities or the underwriters;

                  (j)      provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement;

                  (k)      enter into such customary agreements and take all
such other actions as the holders of a majority of the Registrable Securities
being sold or the underwriters, if any, reasonably request in order to expedite
or facilitate the disposition of such Registrable Securities (including
effecting a stock split or a combination of shares);

                  (l)      otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least twelve months beginning with the first day of Newco's first
full calendar quarter after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder;

                  (m)      permit any holder of Registrable Securities which
holder, in its sole and exclusive judgment, might be deemed to be an underwriter
or a controlling person of Newco, to participate in the preparation of such
registration statement and to require the insertion therein of material,
furnished to Newco in writing, which in the reasonable judgment of such holder
and its counsel should be included; and

                  (n)      in the event of the issuance of any stop order
suspending the effectiveness of a registration statement, or of any order
suspending or preventing the use of any related prospectus or suspending the
qualification of any Common Stock included in such registration statement for
sale in any jurisdiction, Newco will use its reasonable best efforts promptly to
obtain the withdrawal of

                                      -12-

such order.

                  If any such registration or comparable statement refers to any
holder of Registrable Securities by name or otherwise as the holder of any
securities of Newco and if in its sole and exclusive judgment, such holder is or
might be deemed to be a controlling person of Newco, such holder will have the
right to require: (i) the insertion therein of language, in form and substance
satisfactory to such holder and presented to Newco in writing, to the effect
that the holding by such holder of such securities is not to be construed as a
recommendation by such holder of the investment quality of Newco's securities
covered thereby and that such holding does not imply that such holder will
assist in meeting any future financial requirements of Newco; or (ii) in the
event that such reference to such holder by name or otherwise is not required by
the Securities Act or any similar federal statute then in force, the deletion of
the reference to such holder; provided that with respect to this clause (ii)
such holder will furnish to Newco an opinion of counsel to such effect.

                  6.       RECAPITALIZATION; UNDERWRITING; DUE DILIGENCE.

                  (a)      For any Piggyback Registration or Demand Registration
prior to the time Newco becomes subject to the Exchange Act with respect to
Registrable Securities, Newco shall effect a stock split, stock dividend or
stock combination which in the opinion of the underwriters is desirable for the
sale and marketing of the Registrable Securities to the public.

                  (b)      If requested by the underwriters for any underwritten
offering of Registrable Securities pursuant to a registration requested under
this Agreement, Newco shall enter into an underwriting agreement with such
underwriters for such offering, which agreement will contain such
representations and warranties by Newco and such other terms and provisions as
are customarily contained in underwriting agreements of Newco to the extent
relevant and as are customarily contained in underwriting agreements generally
with respect to secondary distributions to the extent relevant, including,
without limitation, indemnification and contribution provisions substantially to
the effect and to the extent provided in Section 7(a), and agreements as to the
provision of opinions of counsel and accountants' letters to the effect and to
the extent provided in Section 5(f). Subject to Section 9 below, the holders of
the Registrable Securities included in such registration shall be parties to any
such underwriting agreement and the representations and warranties by, and the
other agreements on the part of, Newco to and for the benefit of such
underwriters, shall also be made to and for the benefit of the holders of such
Registrable Securities.

                  (c)      In connection with the preparation and filing of each
registration statement registering Registrable Securities under the Securities
Act pursuant to this Agreement, Newco shall give the holders of the Registrable
Securities included in such registration and the underwriters, if any, and their
respective counsel, accountants and agents, the opportunity (but such persons
shall not have the obligation) to review the books and records of Newco and to
discuss the business of Newco with its officers and the independent public
accountants who have certified the financial statements of Newco as shall be
necessary, in the opinion of the holders of such Registrable Securities and such
underwriters or their respective counsel, to conduct a reasonable investigation
within the meaning of the Securities Act.

                  7.       INDEMNIFICATION.

                  (a)      NEWCO INDEMNIFICATION. Newco agrees to indemnify, to
the extent permitted by law, each holder of Registrable Securities, its officers
and directors and each Person who controls such holder (within the meaning of
the Securities Act) and the officers, directors, affiliates, employees and
agents of each of the foregoing (whether or not any litigation is commenced or
threatened and whether or not such indemnified Persons are parties to any
litigation commenced or threatened), against all losses, claims, damages,
liabilities and expenses including, without limitation, attorneys' fees, expert
fees and amounts paid in settlement, resulting from or arising out of any untrue
or alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are caused by or contained in any
information furnished in writing to Newco by such holder expressly for use
therein or by such holder's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto after Newco has
furnished such holder with a sufficient number of copies of the same. In
connection with an underwritten offering, Newco will indemnify such
underwriters, their officers and directors and each Person who controls such
underwriters (within the meaning of the Securities Act) to the same extent as
provided above with respect to the indemnification of the holders of Registrable
Securities. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of the holders of the Registrable
Securities or any underwriter and shall survive the transfer of such securities.
The foregoing indemnity agreement is in addition to any liability that Newco may
otherwise have to the holders of the Registrable Securities or any underwriter
of the Registrable Securities or any controlling Person of the foregoing and the
officers, directors, affiliates, employees and agents of each of the foregoing.

                  (b)      HOLDER INDEMNIFICATION. In connection with any
registration statement in which a holder of Registrable Securities is
participating, each such holder agrees to indemnify, to the extent permitted by
law, Newco, its directors and officers and each Person who controls Newco
(within the meaning of the Securities Act) and the officers, directors,
affiliates, employees and agents of each of the foregoing (whether or not any
litigation is commenced or threatened and whether or not such indemnified
Persons are parties to any litigation commenced or threatened), against any
losses, claims, damages, liabilities and expenses including, without limitation,
attorneys' fees, expert fees and amounts paid in settlement, resulting from or
arising out of any untrue or alleged untrue statement of material fact contained
in the registration statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but only to the extent that such untrue statement or
omission is contained in any information furnished in writing to Newco by such
holder expressly for use in such registration statement; provided, however, that
the obligation to indemnify will be individual to each such holder and will be
limited to the net amount of proceeds received by such holder from the sale of
Registrable Securities pursuant to such registration statement.

                  (c)      RESOLUTION OF CLAIMS. Any Person entitled to
indemnification hereunder will: (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks

                                      -14-
<PAGE>   15
indemnification hereunder; and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

                  (d)      CONTRIBUTION. If the indemnification provided for in
this Section 7 shall for any reason be unavailable (other than in accordance
with its terms) to an indemnified party in respect of any loss, claim, damage,
liability or expense referred to therein, then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage,
liability or expense in such proportion as shall be appropriate to reflect the
relative fault of the indemnifying party on the one hand and the indemnified
party on the other with respect to the statements or omissions which resulted in
such loss, claim, damage, liability or expense as well as any other relevant
equitable considerations. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
indemnifying party on the one hand or the indemnified party on the other. The
amount paid or payable by an indemnified party as a result of the loss, cost,
claim, damage, liability or expense, or action in respect thereof, referred to
above in this Section 7(d) shall be deemed to include, for purposes of this
Section 7(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. In any
event, a holder's obligation to provide contribution pursuant to this Section
7(d) shall be limited to the net amount of proceeds received by such holder from
the sale of Registrable Securities pursuant to such registration statement.

                  (e)      STATE SECURITIES LAWS. Indemnification and
contribution similar to that specified in the preceding paragraphs of this
Section 7 (with appropriate modifications) shall be given by Newco, the holders
of the Registrable Securities and underwriters with respect to any required
registration or other qualification of securities under any state law or
regulation or governmental authority.

                  (f)      OTHER RIGHTS. The obligations of the parties under
this Section 7 shall be in addition to any liability which any party may
otherwise have to any other party.

                                      -15-
<PAGE>   16

                  8.       RULE 144. Newco shall use its reasonable best efforts
to ensure that the conditions to the availability of Rule 144 set forth in
paragraph (c) thereof shall be satisfied. Upon the request of the holders of a
majority of the TPI Registrable Securities or the holders of a majority of the
PCA Registrable Securities, Newco will deliver to such holders a written
statement as to whether it has complied with such requirements.

                  9.       PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No
holder of Registrable Securities may participate in any registration hereunder
which is underwritten unless such holder: (a) agrees to sell such holder's
securities on the basis provided in any underwriting arrangements contemplated
by such offering; and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements; provided, however, that no
holder of Registrable Securities included in any underwritten registration will
be required to make: (i) any representations or warranties to Newco, the
underwriters or other Persons other than representations and warranties
regarding such holder and such holder's intended method of distribution; or (ii)
any indemnities to Newco, the underwriter or other Persons on terms which are
not substantially identical to the provisions in Section 7(b) above.

                  10.      MISCELLANEOUS.

                  (a)      NO INCONSISTENT AGREEMENTS. Newco represents and
warrants to the holders of the Registrable Securities that it has not entered
into, and agrees with the holders of the Registrable Securities that it will not
hereafter enter into, any agreement with respect to its securities which is
inconsistent or conflicts with, or violates the rights granted to the holders of
Registrable Securities in, this Agreement.

                  (b)      ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. In
addition to Newco's obligations under Section 6(a) above, Newco will not take
any action, or permit any change to occur, with respect to its securities which
would adversely affect the ability of the holders of Registrable Securities to
include such Registrable Securities in a registration undertaken pursuant to
this Agreement or which would adversely affect the marketability of such
Registrable Securities in any such registration (including effecting a stock
split or a combination of shares).

                  (c)      REMEDIES. Each holder of Registrable Securities will
have all rights and remedies set forth in this Agreement, Newco's Certificate of
Incorporation and all rights and remedies which such holders have been granted
at any time under any other agreement and all of the rights which such holders
have under any law. Any Person having any rights under any provision of this
Agreement will be entitled to enforce such rights specifically, without posting
a bond or other security, to recover damages by reason of any breach of any
provision of this Agreement and to exercise all other rights granted by law.

                                      -16-
<PAGE>   17

                  (d)      AMENDMENTS; WAIVER. Except as otherwise expressly
provided herein, the provisions of this Agreement may be amended and Newco may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if Newco has obtained the written consent of both: (i)
TPI, as long as it or any of its Affiliates owns any TPI Registrable Securities;
and (ii) PCA, as long as it or any of its Affiliates owns any PCA Registrable
Securities. No other course of dealing between Newco and the holder of any
Registrable Securities or any delay in exercising any rights hereunder or under
the Certificate of Incorporation will operate as a waiver of any rights of any
such holders. For purposes of this Agreement, shares held by Newco or any of its
Subsidiaries will not be deemed to be Registrable Securities. If Newco pays any
consideration to any holder of Registrable Securities for such holder's consent
to any amendment, modification or waiver hereunder, Newco will also pay each
other holder granting its consent hereunder equivalent consideration computed on
a pro rata basis.

                  In the event that the Securities Act, Exchange Act and/or
regulations thereunder, respectively, are amended in a material respect and one
or more of such amendments reduce or diminish the benefits hereunder to the
holders of the Registrable Securities, including, without limitation, amendments
which may be adopted in connection with the Aircraft Carrier Release (any such
reducing or diminishing amendments being referred to herein as "SECURITIES LAW
AMENDMENTS"), Newco shall, upon the written request of both (i) TPI, as long as
it or any of its Affiliates owns any TPI Registrable Securities, and (ii) PCA,
as long as it or any of its Affiliates owns any PCA Registrable Securities,
amend this Agreement to provide the holders of the Registrable Securities with
benefits which, after giving effect to such Securities Law Amendments, are
equivalent to the benefits hereunder absent such Securities Law Amendments.

                  (e)      HEADINGS. The headings in this Agreement are inserted
for convenience only and shall not be deemed to define or limit the scope of any
section or subsection.

                  (f)      NOTICES. All requests, notices, demands or other
communications shall be in writing and will be deemed to have been given when
