     Unisource generated approximately $7 billion in revenues and $184 million
     in operating income, excluding a $50 million restructuring charge.  In
     fiscal 1996, the Company's Printing and Imaging business accounted for
     approximately 68% of total Company revenues and the Supply Systems business
     accounted for approximately 32% of total Company revenues.

                     SECURITIES COVERED BY THIS PROSPECTUS

          The shares of Common Stock covered by this Prospectus are available
     for use in future acquisitions of other businesses or properties, which may
     be similar or dissimilar to Unisource's present activities.  The
     consideration offered by Unisource in such acquisitions, in addition to the
     shares of Common Stock offered hereby, may include cash, debt or other
     securities (which may be convertible into shares of Common Stock covered by
     this Prospectus), or assumption by Unisource of liabilities of the business
     being acquired, or a combination thereof.  It is contemplated that the
     terms of acquisitions will be determined by negotiations between Unisource
     and the owners and/or management of the business or properties to be
     acquired, with Unisource taking into account the quality of management, the
     past and potential earnings power and growth of the business or properties
     to be acquired, and other relevant facts, and it is anticipated that shares
     of Common Stock issued in acquisitions will be valued at a price reasonably
     related to the market value of the Common Stock either at the time the
     terms of the acquisition are tentatively agreed upon or at or about the
     time or times of delivery of the shares.

                                  RISK FACTORS

          Prior to making an investment decision, prospective purchasers should
     consider carefully, in addition to other information contained in the
     Prospectus, the following risk factors.

     COMPETITION

          The Company's Printing and Imaging and Supply Systems businesses
     operate within highly competitive markets.  Unisource's Printing and
     Imaging competitors consist of the distribution units of large paper
     manufacturers (e.g., International Paper's ResourceNet, Mead Corporation's
     Zellerbach and Champion International's Nationwide Paper) and independent
     distributors.  While Unisource is the largest distributor in this market,
     certain Printing and Imaging competitors, principally the distribution
     units of large paper manufacturers, may have greater total financial,
     purchasing and/or sourcing power than Unisource.  In the more fragmented
     Supply Systems business, Unisource competes with a large number of local
     and regional distributors, as well as larger companies, including
     ResourceNet and Zellerbach.  The Company believes that the principal
     competitive factors in these markets include responsiveness to customer
     needs, price, quality of customer service and the range of products
     maintained in inventory.  The Company is responding to such competitive
     conditions by bundling products and services in order to meet all
     customers' Printing and Imaging and Supply Systems needs and by using its
     extensive distribution capabilities to attract national accounts which
     provide consistent and profitable revenue streams.

     QUARTERLY FLUCTUATIONS IN OPERATING RESULTS; SENSITIVITY TO PAPER PRICES

          The Company has experienced fluctuations in revenues and net income
     from quarter to quarter due to a combination of factors, including
     volatility in pulp and paper prices (which may also affect demand for
     Printing and Imaging products), the timing and magnitude of acquisitions
     and the implementation of the Company's restructuring program.  The
     Printing and Imaging business, which accounted for $4.8 billion (68%) and
     $666 million (59%) of the Company's revenues and gross profit,
     respectively, during fiscal 1996, can be significantly impacted by
     volatility in pulp and paper prices.  In fiscal 1995, average prices for
     Printing and Imaging products sold by the Company increased by more than
     24% over average fiscal 1994 levels.  By September 30, 1996, prices for
     those same products declined by more than 16% compared to prices at fiscal
     1995 year-end.  For the three-year period ended September 30, 1996, paper
     prices for uncoated cut size (copy) and coated papers (the two greatest
     volume categories for the Company) ranged from $670 to $1,160 per ton and
     $1,175 to $1,500 per ton, respectively. Volatility in pulp and paper prices
     may alter purchasing patterns and cause customers to defer paper purchases
     and/or deplete inventory levels until long-term price stability occurs.  In
     general, rising paper prices favorably impact the Company through the
     generation of higher gross trading margins.  This is particularly true when
     market conditions allow the Company to quickly pass along increased
     supplier costs to customers and maintain its gross trading margin
     percentage. When such percentage is maintained over a higher revenue base
     that is brought about by increased prices, results are favorably impacted.
     With the exception of increased sales commission expense, which is based
     upon gross trading margins, and is the only significant expense item that
     varies directly with changing paper prices, increases in paper prices do
     not carry a proportionate increase in operating expenses.  Declining paper
     prices negatively impact the Company even when Unisource maintains its
     gross trading margin percentage and volumes because constant volumes and
     trading margin percentages in a declining price environment will produce
     lower revenues and gross trading margins, in absolute terms, and Unisource
     also has certain fixed expenses which impact results regardless of changes
     in paper prices.  Although the Company does not produce paper products and
     is not directly exposed to the production and raw materials risks
     associated therewith, industry overcapacity and overproduction by paper
     suppliers also could adversely affect the Company's revenues and net income
     if such factors produce lower paper prices.  In addition, while the Company
     has been successful in ultimately passing on the effects of price
     increases, there is sometimes a short lag from the time prices are
     increased by producers until the Company is able to effectively pass along
     such increased costs to its customers.

     DELAY IN IMPLEMENTING INFORMATION TECHNOLOGY SYSTEM

          The Company began an ambitious restructuring program in late fiscal
     1993 and has made significant investments in the design, testing and
     implementation of a new information technology system.  The implementation
     of the system, which was originally scheduled to begin in 1995, has been
     delayed to allow for additional enhancements to the system and to better
     prepare field operations for installation. Implementation is now expected
     to be completed by the end of fiscal 1999.  While information technology
     systems currently in use are adequate to support the Company's current
     operations, such systems will not enable the Company to achieve

                                       5
<PAGE>
 
     its current business strategies to realize cost savings through streamlined
     operating and financial functions, increase responsiveness to customers and
     enhance distribution efficiency.  Any significant further delay in
     implementing this program or any significant difficulties in realizing the
     anticipated benefits of such program would delay the Company's ability to
     successfully implement its business strategies and could adversely impact
     the Company's operations and future financial results and condition.

     CERTAIN ANTITAKEOVER PROVISIONS

          The Company's Certificate of Incorporation, By-laws and Stockholder
     Rights Plan and the General Corporation Law of the State of Delaware may
     have the effect, either alone or in combination with each other, of making
     more difficult or discouraging a tender offer, change in control or
     takeover attempt that is opposed by the Company's Board of Directors.  See
     "Description of Capital Stock -  Unisource Common Stock; Delaware
     Antitakeover Provisions," "--Preferred Stock," "--Certain Antitakeover
     Provisions - Unisource Certificate and By-Laws" and "--Stockholder Rights
     Plan."  In addition, provisions in the Company's Tax Sharing Agreement with
     Alco Standard Corporation could have the effect of discouraging or making
     more expensive certain takeover proposals.


                          FORWARD-LOOKING INFORMATION

          This Prospectus contains, and other materials filed or to be filed by
     the Company with the Commission which are incorporated by reference herein,
     as well as information included in oral statements or other written
     statements made or to be made by the Company, contain or will contain or
     include, disclosures which are forward-looking statements within the
     meaning of Section 27A of the Act and Section 21E of the 1934Act.  Such
     forward-looking statements address, among other things, strategic
     initiatives (including plans for transforming the Company's business
     through new information technology systems, sales strategies, market growth
     plans and acquisition and margin enhancement initiatives, capital
     expenditure requirements and financing sources) and anticipated results of
     operations.  See "Management's Discussion and Analysis of Financial
     Condition and Results of Operations," "Business-Strategy," "--Acquisitions"
     and "--Business Transformation and Information Technology System" in the
     1934 Act Registration Statement.  Such forward-looking information is based
     upon management's current plans or expectations and is subject to a number
     of uncertainties and risks that could significantly affect current plans,
     anticipated actions and the Company's future financial condition and
     results.  These uncertainties and risks include, but are not limited to,
     those relating to conducting operations in a competitive environment;
     delays, difficulties and technological changes associated with a large-
     scale systems transformation project; acquisition activities (including
     uncertainties associated with projecting the use of Common Stock as
     acquisition currency when there has been no historic trading market for
     such stock and projecting future cash flows to finance cash-based
     acquisitions); debt service requirements (including sensitivity to
     fluctuation in interest rates); general economic conditions; and changes or
     volatility in paper prices.  As a consequence, current plans, anticipated
     actions

                                       6
<PAGE>
 
     and future financial condition and results may differ from those expressed
     in any forward-looking statements made by or on behalf of the Company.

                              PLAN OF DISTRIBUTION

          Shares of Common Stock will be offered in connection with Unisource's
     or a subsidiary's acquisition of other businesses or properties from time
     to time as described above.  A maximum of 5,000,000 shares of Common Stock
     may be sold pursuant to this Prospectus.  These shares will ordinarily
     represent consideration paid directly upon the acquisition of businesses or
     properties.  The shares may also include shares to be delivered upon the
     exercise or satisfaction of conversion or purchase rights which are created
     in connection with acquisitions or which were previously created or assumed
     by the companies whose businesses or properties were acquired.

                                    RESALES

          Common Stock offered hereby may generally be resold by the persons
     acquiring such shares without further registration under the Act, unless
     such persons are "affiliates" or "underwriters" within the meaning of the
     Act.

          Any person receiving shares offered hereby who is an "affiliate" of
     Unisource may be subject to certain limitations on resale.  An "affiliate"
     is a person who directly, or indirectly through one or more intermediaries,
     controls, or is controlled by, or is under common control with the Company.
     "Control," as used in the preceding sentence, means the direct or indirect
     power to direct or cause the direction of the management and policies of
     the Company through ownership of voting securities, contract or otherwise.
     In the absence of a special relationship between Unisource  and a person
     who receives shares from Unisource in an acquisition transaction (such as
     election of such person to Unisource's board of directors or ownership by
     such person of a significant percentage of Unisource's outstanding Common
     Stock), such a person generally would not be considered an "affiliate" of
     Unisource within the meaning of the Act.  Therefore, the limitations on
     resale applicable to affiliates would not apply to such person.

          Any person receiving shares offered hereby who is an "underwriter" of
     Unisource may also be subject to certain limitations upon resale.  An
     "underwriter" includes a person who purchases Unisource shares with a view
     to the distribution of such shares.  Although an "underwriter" may
     otherwise be subject to certain resale limitations, if such person complies
     with the "safe harbor" provisions of rule 145(d), he or she may freely
     resell shares so long as certain conditions are met.  For example, a person
     who receives shares of Common Stock from Unisource in a typical acquisition
     transaction is deemed to be an "underwriter" as defined by the Act, but
     such person is generally free to sell such shares at any time by complying
     with rule 145(d), which requires that the amount of Common Stock which may
     be sold by such person in any three-month period may not exceed the greater
     of (i) 1% of the Common Stock outstanding as shown by the most recent
     report or statement published by Unisource, or (ii) the average weekly
     trading volume in Common Stock reported on the NYSE Composite tape during
     the four calendar weeks preceding the order to sell.  Such sales must also
     be made in "brokers'

                                       7
<PAGE>
 
     transactions," which are ordinary sales through a broker acting as agent
     without special commission arrangements or selling efforts.

          In order for affiliates or underwriters not protected by Rule 145(d)
     to resell shares offered hereby, Unisource would have to agree 1) to
     provide an opinion to the effect that an exemption applies to such resale,
     2) to amend the Registration Statement of which this Prospectus is a part
     to permit such resales, or 3) to file a new registration statement which
     includes the shares proposed to be resold.  Unless a written agreement
     obligates Unisource to do so, there is no assurance that Unisource will
     agree to provide such opinion, amendment or registration.

                                USE OF PROCEEDS

          The Common Stock offered hereby will be issued directly or indirectly
     in exchange for shares of capital stock of other companies, or in exchange
     for assets used in or related to the business of such companies. The
     proceeds of the sale of Common Stock offered hereby, to the extent such
     proceeds consist of the assets of acquired businesses, will be added to the
     assets of Unisource or a subsidiary.  Cash proceeds, if any, representing
     part of the assets of acquired businesses, will be added to the general
     funds of Unisource or a subsidiary and may be used for general corporate
     purposes, including capital expenditures and working capital requirements.

                            SELECTED FINANCIAL DATA


          The following table summarizes certain selected historical financial
     information of Unisource that has been derived from the audited financial
     statements of Unisource for each of the five years in the period ended
     September 30, 1996.  The historical financial information may not be
     indicative of Unisource's future performance as a stand-alone company.  The
     financial data for the three month periods ended December 31, 1995 and 1996
     are derived from unaudited financial statements.  The unaudited financial
     statements include all adjustments, consisting of normal recurring
     accruals, which Unisource considers necessary for a fair presentation of
     the financial position and the results of operations for these periods.
     Operating results for the three months ended December 31, 1996 are not
     necessarily indicative of the results that may be expected for the entire
     year ending September 30, 1997.  The information set forth below should be
     read in conjunction with "Management's Discussion and Analysis of Financial
     Condition and Results of Operations" and Unisource's Consolidated Financial
     Statements and notes thereto included in the 1934 Act Registration
     Statement. Per share data has not been presented for any periods other than
     December 31, 1996, because Unisource was a wholly-owned subsidiary of Alco
     Standard Corporation during the periods presented and was recapitalized
     prior to the year ended September 30, 1996.

                          DESCRIPTION OF CAPITAL STOCK

               The authorized capital stock of Unisource consists of 250 million
     shares of Unisource Common Stock, par value $0.001 per share, and 10
     million shares of Preferred Stock, par value $0.001 per share (the
     "Preferred Stock").

     UNISOURCE COMMON STOCK; DELAWARE ANTITAKEOVER PROVISIONS

               Holders of shares of Unisource Common Stock are entitled to one
     vote per share on all matters to be voted upon by the stockholders and are
     not entitled to cumulate votes for the election of directors. Subject to
     preferences that may be applicable to any outstanding Preferred Stock,
     holders of shares of Unisource Common Stock are entitled to receive ratably
     such dividends, if any, as may be declared from time to time by the
     Unisource Board of Directors out of funds legally available therefor.  In
     the event of liquidation, dissolution or winding up of Unisource, the
     holders of shares of Unisource Common Stock are entitled to share ratably
     in all assets remaining after payment of liabilities, subject to prior
     distribution rights of Preferred Stock, if any, then outstanding.  Holders
     of Unisource Common Stock have no preemptive, conversion or other
     subscription rights and there are no redemption or sinking fund provisions
     applicable to the Unisource Common Stock.

               Unisource is subject to the provisions of Section 203 of the
     Delaware General Corporation Law ("DGCL").  Subject to certain exceptions,
     Section 203 of the DGCL prohibits a publicly-held Delaware corporation from
     engaging in a "business combination" with an "interested stockholder" for a
     period of three years after the date of the transaction in which the person
     became an interested stockholder. Subject to certain exceptions, an
     "interested stockholder" is a person who, together with affiliates and
     associates, owns, or within three years did own, 15% or more of the
     corporation's voting stock.  A "business combination" includes a merger,
     consolidation, sale or other disposition of assets having an aggregate
     value in excess of 10% of either the aggregate market value of the
     consolidated assets of the corporation or the aggregate market value of all
     the outstanding stock of the corporation, and certain transactions that
     would increase the interested stockholder's proportionate share ownership
     in the corporation or which provide the interested stockholder with a
     financial benefit.  These restrictions do not apply where (i) the business
     combination or the transaction in which the stockholder becomes interested
     is approved by the corporation's board of directors prior to the date the
     interested stockholder acquired its shares, (ii) the interested stockholder
     acquired at least 85% of the outstanding voting stock of the corporation in
     the transaction in which the stockholder became an interested stockholder
     excluding, for determining the number of shares outstanding, shares owned
     by persons who are directors as well as officers and by employee stock
     plans in which participants do not have the right to determine
     confidentially whether shares held subject to the plan will be tendered in
     a tender or exchange offer, or (iii) the business combination is approved
     by the board of directors and the affirmative vote of two-thirds of the
     outstanding voting stock not owned by the interested stockholder at an
     annual or special meeting.  The business combinations provisions of Section
     203 of the DGCL may have the effect of deterring merger proposals, tender
     offers or other attempts to effect changes in control of the Company that
     are not negotiated with and approved by the Board of Directors.

     PREFERRED STOCK

                                       10
<PAGE>
 
               The Amended and Restated Certificate of Incorporation of
     Unisource (the "Unisource Certificate") provides that Unisource may issue
     up to 10 million shares of Preferred Stock.  The Unisource Board of
     Directors has the authority to issue Preferred Stock in one or more series
     and to fix the rights, preferences, privileges and restrictions, including
     the dividend, conversion, voting, redemption (including sinking fund
     provisions), and other rights, liquidation preferences, and the number of
     shares constituting any series and the designations of such series, without
     any further vote or action by the stockholders of Unisource.  Because the
     terms of the Preferred Stock may be fixed by the Unisource Board without
     stockholder action, the Preferred Stock could be issued quickly with terms
     calculated to defeat a proposed takeover of Unisource or to make the
     removal of management of Unisource more difficult.  Under certain
     circumstances this could have the effect of decreasing the market price of
     the Unisource Common Stock.  The Company has authorized a class of series
     Preferred Stock in connection with the authorization of its Stockholder
     Rights Plan.  See "-Stockholder Rights Plan."

     CERTAIN ANTITAKEOVER PROVISIONS - UNISOURCE CERTIFICATE AND BY-LAWS

               Certain provisions of the Unisource Certificate and By-laws may
     have the effect, either alone or in combination with each other, of making
     more difficult or discouraging a tender offer, takeover attempt or change
     in control that is opposed by Unisource's Board of Directors but that a
     stockholder might consider to be in its best interest.  The Company
     believes that such provisions are necessary to enable the Company to
     develop its business in a manner that will foster its long-term growth
     without disruption caused by the threat of a takeover not deemed by the
     Board of Directors to be in the best interests of the Company and its
     stockholders.  These provisions are summarized in the following paragraphs.

               Classified Board of Directors.  The Unisource Certificate and By-
     laws provide for the division of the Board  into three classes of
     directors, with the classes to be as nearly equal in number as possible.
     The Certificate and By-laws provide that of the initial directors of the
     Company, one-third will continue to serve until the Annual Meeting of
     Stockholders next held after September 30, 1997, one-third will continue to
     serve until the Annual Meeting of Stockholders next held after September
     30, 1998, and one-third will continue to serve until the Annual Meeting of
     Stockholders next held after September 30, 1999.

               The classification of directors will have the effect of making it
     more difficult for stockholders to change the composition of the Board of
     Directors.  At least two annual meetings of stockholders, instead of one,
     will generally be required to effect a change in a majority of the Board of
     Directors.  Such a delay may help ensure that the Company's directors, if
     confronted by a holder attempting to force a proxy contest, a tender or
     exchange offer, or an extraordinary corporate transaction, would have
     sufficient time to review the proposal as well as any available
     alternatives to the proposal and to act in what they believe to be the best
     interest of the stockholders.  The classification provisions will apply to
     every election of directors, however, regardless of whether a change in the
     composition of the Board would be beneficial to the Company and its
     stockholders and whether or not a majority of the Company's stockholders
     believe that such a change would be desirable.

               The classification provisions could also have the effect of
     discouraging a third party from initiating a proxy contest, making a tender
     offer or otherwise attempting to obtain control of the Company, even though
     such an attempt might be beneficial to the Company and its stockholders.
     The classification of

                                       11
<PAGE>
 
     the Board could thus increase the likelihood that incumbent directors will
     retain their positions.  In addition, because the classification provisions
     may discourage accumulations of large blocks of the Company's stock by
     purchasers whose objective is to take control of the Company and remove a
     majority of the Board, the classification of the Board could tend to reduce
     the likelihood of fluctuations in the market price of the Company Common
     Stock that might result from accumulations of large blocks for such a
     purpose.  Accordingly, stockholders could be deprived of certain
     opportunities to sell their shares of Company Common Stock at a higher
     market price than might otherwise be the case.

               Number of Directors; Removal of Directors; Vacancies.  The By-
     laws provide that the number of directors of Unisource shall be a number
     between six and seventeen which shall be fixed by resolution adopted by
     either (i) a majority of the entire Board of Directors or (ii) the
     affirmative vote of the holders of at least 66 2/3% of the voting power of
     all of the shares of Unisource entitled to vote generally in the election
     of directors voting together as a single class.

               The Unisource Certificate and By-laws also provide that, subject
     to the rights of holders of any Preferred Stock then outstanding and any
     requirements of law, directors may be removed only for cause by the
     affirmative vote of the holders of at least 66 2/3% of the outstanding
     shares of Unisource then entitled to vote generally in the election of
     directors, voting as a single voting group.  Subject to the rights of
     holders of any outstanding Preferred Stock issued by Unisource, vacancies
     on the Board of Directors may be filled only by the Board of Directors, the
     stockholders acting at an annual meeting or, if the vacancy is with respect
     to a director elected by a voting group, by action of any other directors
     elected by such voting group or such voting group.

               Business Conducted at Meetings; Director Nominations.  The By-
     laws provide that in order to bring matters before the annual meetings of
     stockholders, stockholders must give notice to the Company containing
     certain information within 60 to 90 days prior to the anniversary date of
     the previous year's annual meeting or, if the date of the annual meeting is
     not within 30 days of the anniversary date of the previous year's annual
     meeting, no later than the close of business on the tenth day following the
     day on which notice of the date of such meeting was mailed or public
     disclosure of the date of the meeting of stockholders was made, whichever
     first occurs.  In order to nominate candidates for directors of the
     Company, stockholders must give notice to the Company containing certain
     information within 60 to 90 days prior to the anniversary date of the
     previous year's annual meeting or, if the date of an annual meeting is not
     within 30 days of the anniversary of the previous year's annual meeting,
     not earlier than 90 days prior to the annual meeting and not later than the
     close of business on the tenth day following the day on which notice of the
     date of such meeting was mailed or public disclosure of the date of the
     meeting of stockholders was made, whichever first occurs.

               Special Meeting of Stockholders.  The DGCL provides that special
     meetings of stockholders may be called by the Board of Directors of
     Unisource or any person authorized by the Unisource Certificate or By-laws
     to call a special meeting.  The By-laws provide that special meetings may
     be called by the Board of Directors or any person authorized by the Board
     of Directors to call a special meeting.

               No Stockholder Action by Written Consent; Stockholder Action at
     Meetings.  The Unisource Certificate and By-Laws provide that stockholder
     action can be taken only at an annual or special meeting of stockholders,
     and prohibit stockholder action by written consent in lieu of a meeting.

                                       12

               Supermajority Voting.  The Unisource Certificate requires the
     approval of the holders of at least 66% of the voting power of all of the
     shares entitled to vote to alter, amend, repeal or adopt any provision
     inconsistent with or limiting the effect of provisions of certain
     enumerated antitakeover provisions in the Unisource Certificate and By-
     laws, including the anti-takeover provisions listed above. The Board of
     Directors may amend, supplement or repeal the By-laws at any time, except
     as limited by law.

     STOCKHOLDER RIGHTS PLAN

               The Company's Board of Directors has adopted a Stockholder Rights
     Plan (the "Stockholder Rights Plan"). Initially, ownership of the rights
     under the Stockholder Rights Plan (the "Rights") will be evidenced by
     Common Stock certificates representing shares then outstanding and, except
     as described below, no separate Rights certificates will be distributed and
     Rights will attach to and trade with Unisource Common Stock.

               Rights Distribution Date. The Rights will separate from the
     Unisource Common Stock and a distribution date ("Rights Distribution Date")
     will occur upon the earlier of (i) ten business days following a public
     announcement that a person or group of affiliated or associated persons (an
     "Acquiring Person") has acquired, or obtained the right to acquire,
     beneficial ownership of 20% or more of the outstanding Unisource Common
     Stock (the "Stock Acquisition Date"), or (ii) within ten business days (or
     such later date as may be determined by the Board of Directors prior to
     such time as any person or group of affiliated or associated persons
     becomes an Acquiring Person) following the commencement of a tender offer
     or exchange offer that would result in a person or group beneficially
     owning 20% or more of the outstanding Common Stock (excluding Unisource and
     its subsidiaries and benefit plans).

               Exercise of Rights; Term of Plan.  The Rights are not exercisable
     until the Rights Distribution Date and will expire at the close of business
     on November 8, 2006, unless earlier redeemed by the Company as described
     below or unless certain transactions set forth in the Stockholder Rights
     Plan have occurred.

               Except in the circumstances described below, after the Rights
     Distribution Date, each Right will be exercisable into one one-hundredth of
     a Series A Preferred Share (a "Series A Preferred Share Fraction").  The
     voting and dividend rights of the Series A Preferred Shares are subject to
     adjustment in the event of dividends, subdivisions and combinations with
     respect to the Unisource Common Stock.  In lieu of issuing certificates for
     Series A Preferred Share Fractions which are less than an integral multiple
     of one Series A Preferred Share (i.e., 100 Series A Preferred Share
     Fractions), the Company may pay cash representing the current market value
     of the Series A Preferred Share Fractions.

               Flip-In Rights.  In the event that (i) at any time following the
     Stock Acquisition Date, the Company is the surviving corporation in a
     merger with an Acquiring Person and its Common Stock remains outstanding,
     (ii) a person, including affiliates and associates, becomes the beneficial
     owner of more than 20% of the then outstanding Unisource Common Stock
     (unless such acquisition is made pursuant to a tender or exchange offer for
     all outstanding Common Stock of the Company, upon terms and conditions
     determined by a majority of the Continuing Directors (as defined below) to
     be in the best interest of the

                                       13
<PAGE>
 
     Company and its stockholders (a "Qualifying Offer")), (iii) an Acquiring
     Person, at any time following a Stock Acquisition Date, engages in one or
     more "self-dealing" transactions as set forth in the Stockholder Rights
     Plan, or (iv) during such time as there is an Acquiring Person an event
     occurs that results in such Acquiring Person's ownership interest being
     increased by more than one percent (e.g., a reverse stock split), each
     holder of a Right will thereafter have the right to receive, upon exercise,
     Unisource Common Stock (or, in certain circumstances, cash, property or
     other securities of the Company) having a value equal to approximately two
     times the exercise price of the Right.  In lieu of requiring payment of the
     purchase price upon exercise of the Rights following any such event, the
     Company, by action of a majority of the Continuing Directors in office at
     the time, may permit the holders simply to surrender the Rights, in which
     event they would be entitled to receive Unisource Common Stock (and other
     property, as the case may be) with a value of 50% of what could otherwise
     be purchased by payment of the full Purchase Price.  Notwithstanding any of
     the foregoing, following the occurrence of any of the events set forth in
     clauses (i), (ii), (iii) or (iv) of this paragraph, all Rights that are, or
     (under certain circumstances specified in the Stockholder Rights Plan)
     were, beneficially owned by any Acquiring Person who was involved in the
     transaction giving rise to any such event will be null and void.  However,
     Rights are not exercisable following the occurrence of any of the events
     set forth above until such time as the Rights are no longer redeemable by
     the Company as set forth below.

               Flip-Over Rights.  In the event that, at any time following the
     Stock Acquisition Date, (i) the Company is acquired in a merger or other
     business combination transaction in which the Company is not the surviving
     corporation (other than a merger that follows a Qualifying Offer), or (ii)
     50% or more of the Company's assets or earning power is sold or
     transferred, each holder of a Right (except Rights that previously have
     been voided as set forth above) shall thereafter have the right to receive,
     upon exercise, common shares of the acquiring company having a value equal
     to approximately two times the exercise price of the Rights. Again,
     provision is made to permit, at the option of the Company, surrender of the
     Rights in exchange for one-half of the value otherwise purchasable. The
     events set forth in this paragraph and in the preceding paragraph are
     referred to as the "Triggering Events."

               Antidilution Adjustments.  The Purchase Price payable and/or the
     number of units of Series A Preferred Shares or other securities or
     property issuable upon exercise of the Rights are subject to adjustment
     from time to time to prevent dilution (i) in the event of a stock dividend
     on, or a subdivision, combination or reclassification of, the Series A
     Preferred Shares, (ii) if holders of the Series A Preferred Shares are
     granted certain rights or warrants to subscribe for Series A Preferred
     Shares or convertible securities at less than the current market price of
     the Series A Preferred Shares, or (iii) upon the distribution to holders of
     the Series A Preferred Shares of evidences of indebtedness or assets
     (excluding regular quarterly dividends) or of subscription rights or
     warrants (other than those referred to above). Similar dilution protection
     exists with respect to transactions affecting Common Stock similar to those
     described in clauses (i)-(iii) above.

               Redemption.  At any time until ten days following the Stock
     Acquisition Date, the Company may redeem the Rights in whole, but not in
     part, at a price of $.01 per Right.  That ten day redemption period may be
     extended by the Board of Directors so long as the Rights are still
     redeemable.  Under certain circumstances set forth in the Stockholder
     Rights Plan, the decision to redeem will require the concurrence of the
     Continuing Directors (as defined below).  Immediately upon the action of
     the Board of Directors ordering redemption of the Rights, with, where
     required, the concurrence of the Continuing

                                       14
<PAGE>
 
     Directors, the Rights will terminate and the only rights of the holders of
     Rights will be to the right to receive the $.01 per Right redemption price.

               The term "Continuing Directors" means any member of the Board of
     Directors of the Company who was a member of the Board prior to the date of
     the Stockholder Rights Plan, and any person who is subsequently elected to
     the Board if such person's nomination for election to the Board is
     recommended or approved by a majority of the Continuing Directors, but
     shall not include an Acquiring Person, or an affiliate or associate of an
     Acquiring Person, or any representative of the foregoing entities.

               No Stockholder Rights Associated with Rights Before Exercise; Tax
     Consequences.  Until a Right is exercised, the holder thereof, as such,
     will have no rights as a stockholder of the Company, including, without
     limitation, the right to vote or to receive dividends.  While the
     distribution of the Rights will not be taxable to stockholders or to the
     Company, stockholders may, depending upon the circumstances, recognize
     taxable income in the event that the Rights become exercisable for Series A
     Preferred Shares (or other consideration) of the Company or for common
     shares of the acquiring company as set forth above.  See "-Flip-Over
     Rights."

               Amendment.  Other than those provisions relating to the principal
     economic terms of the Rights, any of the provisions of the Stockholder
     Rights Plan may be amended by the Board of Directors of the Company prior
     to the Rights Distribution Date.  After the Rights Distribution Date, the
     provisions of the Stockholder Rights Plan may be amended by the Board (in
     certain circumstances, with the concurrence of a majority of the Continuing
     Directors) in order to cure any ambiguity, to make changes that do not
     adversely affect the interests of the holders of Rights (excluding the
     interests of any Acquiring Person), or to shorten or lengthen any time
     period under the Stockholder Rights Plan; provided, however, that no
     amendment to adjust the time period governing redemption shall be made at
     such time as the Rights are not redeemable.

               Effect of Stockholders Rights Plan.  The Rights have certain
     defensive effects.  The Rights will cause substantial dilution to a person
     or group that attempts to acquire the Company without conditioning the
     offer on a substantial number of Rights being acquired or redeemed.  The
     Rights should not interfere with any merger or other business combination
     approved by the Board of Directors of the Company because (i) the Board of
     Directors (under certain circumstances, with the concurrence of the
     Continuing Directors) may, at its option, at any time prior to the close of
     business on the earlier of (a) the tenth day following the Stock
     Acquisition Date or (b) November 8, 2006, redeem all of the then
     outstanding Rights at $.01 per Right, and (ii) in any event, the
     Stockholder Rights Plan does not apply to a tender or exchange offer for
     all outstanding shares of the Company which is determined by a majority of
     the Continuing Directors to be a Qualifying Offer.  The Board of Directors
     may, as discussed above, extend the ten day redemption period so long as
     the Rights are still redeemable.  See "--Redemption."

                PART II.  INFORMATION NOT REQUIRED IN PROSPECTUS

     ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

               Section 145 of the DGCL ("Section 145") permits indemnification
     of directors, officers, agents and controlling persons of a corporation
     under certain conditions and subject to certain limitations.  Section 145
     empowers a corporation to indemnify any person who was or is a party or is
     threatened to be made a party to any threatened, pending or completed
     action, suit or proceeding, whether civil, criminal, administrative or
     investigative, by reason of the fact that such person is or was a director,
     officer or agent of the corporation or another enterprise if serving at the
     request of the corporation.  Depending on the character of the proceeding,
     a corporation may indemnify against expenses (including attorneys' fees),
     judgments, fines and amounts paid in settlement actually and reasonably
     incurred in connection with such action, suit or proceeding if the person
     indemnified acted in good faith and in a manner such person reasonably
     believed to be in or not opposed to, the best interests of the corporation,
     and, with respect to any criminal action or proceeding, had no reasonable
     cause to believe such person's conduct was unlawful.  In the case of an
     action by or in the right of the Company, no indemnification may be made
     with respect to any claim, issue or matter as to which such person shall
     have been adjudged to be liable to the corporation unless and only to the
     extent that the Delaware Court of Chancery or the court in which such
     action or suit was brought shall determine that despite the adjudication of
     liability such person is fairly and reasonably entitled to indemnity for
     such expenses which the court shall deem proper.  Section 145 further
     provides that to the extent a director or officer of the Company has been
     successful in the defense of any action, suit or proceeding referred to
     above or in the defense of any claim, issue or matter therein, such person
     shall be indemnified against expenses (including attorneys' fees) actually
     and reasonably incurred by such person in connection therewith.

               Unisource's By-laws contain provisions for indemnification of
     directors, officers, employees and agents to the fullest extent permitted
     by Section 145 and Delaware law which, in general, presently requires that
     the individual act in good faith and in a manner he or she reasonably
     believed to be in or not opposed to the Company's best interests and, in
     the case of any criminal proceedings, that the individual has no reason to
     believe his or her conduct was unlawful.  Unisource's By-laws also permit
     Unisource to purchase insurance and Unisource has purchased and maintains
     insurance on behalf of Unisource directors, officers, employees and agents
     against any liability asserted against such person and incurred by such
     person in any such capacity, or arising out of such person's status as
     such, whether or not Unisource would have the power to indemnify such
     person against such liability under the foregoing provision of the By-laws.

     ITEM 22.  UNDERTAKINGS

     ITEM 22.  UNDERTAKINGS

       Insofar as indemnification for liabilities arising under the Securities
     Act of 1933 may be permitted to directors, officers and controlling persons
     of the registrant pursuant to the provisions described in Item 20, or
     otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the registrant of expenses incurred or paid by a director,
     officer or controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by the final
     adjudication of such issue.

               The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which any offers or sales are
     being made, a post-effective amendment to the Registration Statement:

               (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

               (ii) To reflect in the prospectus any facts or events arising
     after the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high and of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective Registration Statement;

               (iii)   To include any material information with respect to the
     plan of distribution not previously disclosed in the Registration Statement
     or any other material change to such information in the Registration
     Statement.

               (2) That for the purpose of determining any liability under the
     Act each such post-effective amendment may be deemed to be a new
     registration statement relating to the

                                      II-3
<PAGE>
 
     securities being offered therein and the offering of such securities at the
     time may be deemed to be the initial bona fide offering thereof.

               (3) To remove from registration by  means of a post-effective
     amendment any of the securities which are being registered which remain
     unsold at the termination of the offering.

               (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
     of 1934 that is incorporated by reference in the Registration Statement
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

               (5) To deliver or cause to be delivered with the Prospectus, to

     securities subject to Rule 415, will be filed as part of an amendment to
     the Registration Statement and will not be used until such amendment is
     effective, and that, for purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

     Preferred Stock in one or more series (the "Series Preferred Stock") and,
     by filing a certificate pursuant to the GCL (hereinafter referred to as a
     "Preferred Stock Designation"), to establish the number of shares to be
     included in each such series, and to fix the designations, preferences and
     relative, participating, optional or other special rights of the shares of
     each such series and the qualifications, limitations or restrictions
     thereof, as shall be stated and expressed in the resolution or resolutions
     providing for the issue thereof adopted by the Board of Directors,
     including, but not limited to, the following:

                                      -1-
<PAGE>
 
         (1) the designation of and the number of shares constituting such
     series, which number the Board of Director may thereafter (except as
     otherwise provided in the Preferred Stock Designation) increase or decrease
     (but not below the number of shares of such series then outstanding);

         (2) the dividend rate for the payment of dividends on such series, if
     any, the conditions and dates upon which such dividends shall be payable,
     the preference or relation which such dividends, if any, shall bear to the
     dividends payable on any other class or classes of or any other series of
     capital stock, the conditions and dates upon which such dividends, if any,
     shall be payable, and whether such dividends, if any, shall be cumulative
     or non-cumulative;

         (3) whether the shares of such series shall be subject to redemption by
     the Corporation, and, if made subject to such redemption, the times, prices
     and other terms and conditions of such redemption;

         (4) the terms and amount of any sinking fund provided for the

     or exchangeable for shares of any other class or classes of, any other
     series of any class or classes of capital stock of, or any other security
     of, the Corporation or any other corporation, and, if provision be made for
     any such conversion or exchange, the times, prices, rates, adjustments and
     any other terms and conditions of such conversion or exchange;

         (6) the extent, if any, to which the holders of the shares of such
     series shall be entitled to vote as a class or otherwise with respect to

                                      -2-
<PAGE>
 
     of that series.

     (ii) The first series of the Series Preferred Stock, par value $0.001 per
share, shall consist of 1,500,000 shares and shall be designated as Series A
Junior Participating Preferred Shares (the "Series A Preferred Shares").  The
voting rights, designations, preferences, qualifications, privileges,
limitations, restrictions, options, conversion rights and other special or
relative rights of the Series A Preferred Shares are as follows:

        (1)  Dividends and Distributions.
             --------------------------- 

             (a) The rate of dividends payable per share of Series A Preferred
        Shares on the first day of January, April, July and October in each year
        or such other quarterly payment date as shall be specified by the Board
        of Directors (each such date being referred to herein as a "Quarterly
        Dividend Payment Date"), commencing on the first Quarterly Dividend
        Payment Date after the first issuance of a share or fraction of a share
        of the Series A Preferred Shares, shall be (rounded to the nearest cent)
        equal to the greater of (i) $4.00 or (ii) subject to the provision for
        adjustment hereinafter set forth, 100 times the aggregate per share
        amount of all cash dividends, and 100 times the aggregate per share
        amount (payable in cash, based upon the fair market value at the time
        the non-cash dividend or other distribution is declared or paid as
        determined in good faith by the Board of Directors) of all non-cash
        dividends or other distributions other than a dividend payable in shares
        of Common Stock or a subdivision of the outstanding shares of Common
        Stock (by reclassification or otherwise), declared on the Common Stock,
        par value $0.001 per share, of the Corporation since the immediately
        preceding Quarterly Dividend Payment Date, or, with respect to the first
        Quarterly Dividend Payment Date, since the first issuance of any share
        or fraction of a share of the Series A Preferred Shares. Dividends on
        the Series A Preferred Shares shall be paid out of funds legally
        available for such purpose. In the event the Corporation shall at any
        time after December 11, 1996 (the "Rights Declaration Date") (i) declare
        any dividend on Common Stock payable in shares of Common Stock, (ii)
        subdivide the outstanding shares of Common Stock, or (iii) combine the
        outstanding shares of Common Stock into a smaller number of shares, then
        in each such case the amounts to which holders of Series A Preferred
        Shares were entitled immediately prior to such event under clause (ii)
        of the preceding sentence shall be adjusted by multiplying each such
        amount by a fraction the numerator of which is the number of shares of
        Common Stock outstanding immediately after such event and the
        denominator of which is the number of shares of Common Stock that were
        outstanding immediately prior to such event. 

             (b) Dividends shall begin to accrue and be cumulative on

                                      -3-
<PAGE>
 
        outstanding Series A Preferred Shares from the Quarterly Dividend
        Payment Date next preceding the date of issue of such Series A Preferred
        Shares, unless the date of issue of such shares is prior to the record
        date for the first Quarterly Dividend Payment Date, in which case
        dividends on such shares shall begin to accrue from the date of issue of
        such shares, or unless the date of issue is a Quarterly Dividend Payment
        Date or is a date after the record date for the determination of holders
        of Series A Preferred Shares entitled to receive a quarterly dividend
        and before such Quarterly Dividend Payment Date, in either of which
        events such dividends shall begin to accrue and be cumulative from such
        quarterly Dividend Payment Date. Accrued but unpaid dividends shall not
        bear interest. Dividends paid on the Series A Preferred Shares in an
        amount less than the total amount of such dividends at the time accrued
        and payable on such shares shall be allocated pro rata on a share-by-
        share basis among all such shares at the time outstanding.

        (2) Voting Rights. In addition to any other voting rights required by
            -------------    
        law, the holders of Series A Preferred Shares shall have the following
        voting rights:

             (a) Subject to the provision for adjustment hereinafter set forth,
        each Series A Preferred Share shall entitle the holder thereof to 100
        votes on all matters submitted to a vote of the stockholders of the
        Corporation. In the event the Corporation shall at any time after the
        Rights Declaration Date (i) declare any dividend on Common Stock payable
        in shares of Common Stock, (ii) subdivide the outstanding shares of
        Common Stock, or (iii) combine the outstanding shares of Common Stock
        into a smaller number of shares, then in each such case the number of
        votes per share to which holders of Series A Preferred Shares were
        entitled immediately prior to such event shall be adjusted by
        multiplying such number by a fraction the numerator of which is the
        number of shares of Common Stock outstanding immediately after such
        event and the denominator of which is the number of shares of Common
        Stock that were outstanding immediately prior to such event.

             (b) In the event that dividends upon the Series A Preferred Shares
        shall be in arrears to an amount equal to six full quarterly dividends
        thereon, the holders of such Series A Preferred Shares shall become
        entitled to the extent hereinafter provided to vote noncumulatively at
        all elections of directors of the Corporation, and to receive notice of
        all stockholders' meetings to be held for such purpose. At such
        meetings, to the extent that directors are being elected, the holders of
        such Series A Preferred Shares voting as a class shall be entitled
        solely to elect two 

                                      -4-
<PAGE>
 
        members of the Board of Directors of the Corporation; and all other
        directors of the Corporation shall be elected by the other stockholders
        of the Corporation entitled to vote in the election of directors. Such
        voting rights of the holders of such Series A Preferred Shares shall
        continue until all accumulated and unpaid dividends thereon shall have
        been paid or funds sufficient therefor set aside, whereupon all such
        voting rights of the holders of shares of such series shall cease,
        subject to being again revived from time to time upon the reoccurrence
        of the conditions above described as giving rise thereto.

        At any time when such right to elect directors separately as a class
        shall have so vested, the Corporation may, and upon the written request
        of the holders of record of not less than 20% of the then outstanding
        total number of shares of all the Series A Preferred Shares having the
        right to elect directors in such circumstances shall, call a special
        meeting of holders of such Series A Preferred Shares for the election of
        directors. In the case of such a written request, such special meeting
        shall be held within 90 days after the delivery of such request, and, in
        either case, at the place and upon the notice provided by law and in the
        By-laws of the Corporation; provided, that the Corporation shall not be
        required to call such a special meeting if such request is received less
        than 120 days before the date fixed for the next ensuing annual or
        special meeting of stockholders of the Corporation. Upon the mailing of
        the notice of such special meeting to the holders of such Series A
        Preferred Shares, or, if no such meeting be held, then upon the mailing
        of the notice of the next annual or special meeting of stockholders for
        the election of directors, the number of directors of the Corporation
        shall, ipso facto, be increased to the extent, but only to the extent,
        necessary to provide sufficient vacancies to enable the holders of such
        Series A Preferred Shares to elect the two directors hereinabove
        provided for, and all such vacancies shall be filled only by vote of the
        holders of such Series A Preferred Shares as hereinabove provided.
        Whenever the number of directors of the Corporation shall have been
        increased, the number as so increased may thereafter be further
        increased or decreased in such manner as may be permitted by the By-laws
        and without the vote of the holders of Series A Preferred Shares,
        provided that no such action shall impair the right of the holders of
        Series A Preferred Shares to elect and to be represented by two
        directors as herein provided.

        So long as the holders of Series A Preferred Shares are entitled
        hereunder to voting rights, any vacancy in the Board of Directors caused
        by the death or resignation of any director elected by the holders of
        Series A Preferred Shares, shall, until the next meeting of stockholders
        for the election of directors, in each case be filled by the remaining
        director elected by the 

                                      -5-
<PAGE>
 
        holders of Series A Preferred Shares having the
        right to elect directors in such circumstances.

        Upon termination of the voting rights of the holders of any series of
        Series A Preferred Shares the terms of office of all persons who shall
        have been elected directors of the Corporation by vote of the holders of
        Series A Preferred Shares or by a director elected by such holders shall
        forthwith terminate.

             (c) Except as otherwise provided herein, in this Certificate of
        Incorporation of the Corporation or by law, the holders of Series A
        Preferred Shares and the holders of Common Stock (and the holders of
        shares of any other series or class entitled to vote thereon) shall vote
        together as one class on all matters submitted to a vote of stockholders
        of the Corporation.

        (3) Reacquired Shares. Any Series A Preferred Shares purchased or
            -----------------
        otherwise acquired by the Corporation in any manner whatsoever shall be
        retired and canceled promptly after the acquisition thereof. All such
        shares shall upon their cancellation become authorized but unissued
        Series Preferred Stock and may be reissued as part of a new series of
        Series Preferred Stock to be created by resolution or resolutions of the
        Board of Directors.

        (4) Liquidation, Dissolution or Winding Up. 
            --------------------------------------
        In the event of any voluntary or involuntary liquidation, dissolution or
        winding up of the Corporation, the holders of Series A Preferred Shares
        shall be entitled to receive the greater of (a) $100 per share, plus
        accrued dividends to the date of distribution, whether or not earned or
        declared, or (b) an amount per share, subject to the provision for
        adjustment hereinafter set forth, equal to 100 times the aggregate
        amount to be distributed per share to holders of Common Stock. In the
        event the Corporation shall at any time after the Rights Declaration
        Date (i) declare any dividend on Common Stock payable in shares of
        Common Stock, (ii) subdivide the outstanding shares of Common Stock, or
        (iii) combine the outstanding shares of Common Stock into a smaller
        number of shares, then in each such case the amount to which holders of
        Series A Preferred Shares were entitled immediately prior to such event
        pursuant to clause (b) of the preceding sentence shall be adjusted by
        multiplying such amount by a fraction the numerator of which is the
        number of shares of Common Stock outstanding immediately after such
        event and the denominator of which is the number of shares of Common
        Stock that were outstanding immediately prior to such event. 

        (5)  Consolidation, Merger, etc.  In case the Corporation shall enter 
             --------------------------
        into  

                                      -6-
<PAGE>
 
        any consolidation, merger, combination or other transaction in
        which the shares of Common Stock are exchanged for or changed into other
        stock or securities, cash and/or any other property, then in any such
        case the Series A Preferred Shares shall at the same time be similarly
        exchanged or changed in an amount per share (subject to the provision
        for adjustment hereinafter set forth) equal to 100 times the aggregate
        amount of stock, securities, cash and/or any other property (payable in
        kind), as the case may be, into which or for which each share of Common
        Stock is changed or exchanged. In the event the Corporation shall at any
        time after the Rights Declaration Date (i) declare any dividend on
        Common Stock payable in shares of Common Stock, (ii) subdivide the
        outstanding shares of Common Stock, or (iii) combine the outstanding
        shares of Common Stock into a smaller number of shares, then in each
        such case the amount set forth in the preceding sentence with respect to
        the exchange or change of shares of Series A Preferred Shares shall be
        adjusted by multiplying such amount by a fraction the numerator of which
        is the number of shares of Common Stock outstanding immediately after
        such event and the denominator of which is the number of shares of
        Common Stock that were outstanding immediately prior to such event.

        (6)  No Redemption.  The Series A Preferred Shares shall not be 
             -------------
        redeemable.
                                                              

        (7)  Ranking.  The Series A Preferred Shares shall rank junior to all 
             ------- 
        other series of the Corporation's Series Preferred Stock as to the
        payment of dividends and the distribution of assets, unless the terms of
        any such series shall provide otherwise.

        (8)  Fractional Shares.  Series A Preferred Shares may be issued in 
             ----------------- 
        fractions of a share which shall entitle the holder, in proportion to
        such holder's fractional shares, to exercise voting rights, receive
        dividends, participate in distributions and to have the benefit of all
        other rights of holders of Series A Preferred Shares.

     share of Common Stock held by such holder of record on the books of the
     Corporation for the election of directors and on all other matters on which
     stockholders of the Corporation are entitled to vote.  Subject to any
     rights that may be conferred upon any holders of Preferred Stock or any
     other series or class of stock as set forth in this Certificate of
     Incorporation (excluding Common Stock), upon dissolution, the holders of
     Common Stock then outstanding shall be entitled to receive the net assets
     of the Corporation.  Such net assets shall be divided among and paid to the
     holders of Common Stock, on a pro-rata basis, according to the number of
     shares of Common Stock held by them.  Subject to any rights that may be
     conferred upon any holders of Preferred Stock or any other series or class
     of stock as set forth in this Certificate of Incorporation (excluding
     Common Stock), the holders of shares of Common Stock shall be entitled to
     receive, when and if declared by the Board of Directors, out of the assets
     of the Corporation which are by law available therefor, dividends payable
     either in cash, in stock or otherwise.

     Stock or any other series or class of stock as set forth in this
     Certificate of Incorporation (excluding Common Stock) to elect additional
     directors under specified circumstances, the number of directors of the
     Corporation shall be fixed, and may be increased or decreased from time to
     time, in such a manner as may be prescribed by the By-laws of the
     Corporation.

          B.  Unless and except to the extent that the By-laws of the
     Corporation shall so require, the election of directors of the Corporation
     need not be by written ballot.

          C.  The directors, other than those who may be elected by the holders
     of any series of Preferred Stock or any other series or class of stock
     (excluding Common Stock) as set forth in this Certificate of Incorporation,
     shall be divided into three classes as nearly equal in size as possible and
     designated as Class I, Class II and Class III.  Class I directors shall be
     initially elected for a term expiring at the annual meeting of stockholders
     next held after September 30, 1997, Class II directors shall be initially
     elected for a term expiring at the annual meeting of stockholders next held
     after September 30, 1998, and Class III directors shall be initially
     elected for a term expiring at the annual meeting of stockholders next held
     after September 30, 1999.  Members of each class shall

                                      -8-
<PAGE>
 
     hold office until their successors are elected and qualified.  At each
     annual meeting of the stockholders of the Corporation, the successors of
     the class of directors whose term expires at that meeting shall be elected
     to hold office for a term expiring at the annual meeting of stockholders
     held in the third year following the year of their election, and until
     their successors are elected and qualified.

          D.  Advance notice of stockholder nominations for the election of
     directors and advance notice of other stockholder action proposed to be
     taken at a stockholder's meeting shall be given in the manner provided in
     the By-laws of the Corporation.

          E. Subject to the rights of the holders of any series of Preferred
     Stock or any other series or class of stock (excluding Common Stock) as set
     forth in the Certificate of Incorporation to elect directors under
     specified circumstances and applicable law, any director may be removed
     from office at any time, but only for cause and only by the affirmative
     vote of the holders of at least 66 2/3% of the voting power of all the
     shares of the Corporation entitled to vote generally in the election of
     directors, voting together as a single class. Vacancies in the Board of
     Directors shall be filled in the manner provided in the By-laws of the
     Corporation.

          F. Subject to the rights of the holders of any Preferred Stock or any
     other series or class of stock (excluding Common Stock) set forth in the
     Certificate of Incorporation, a special meeting of the stockholders shall
     be called only by the secretary of the Corporation at the request of (i) a
     majority of the total number of directors which the Corporation at the time
     would have if there were no vacancies or (ii) by any person authorized by
     the Board of Directors (through a vote of a majority of the total number of
     directors which the Corporation at the time would have if there were no
     vacancies) to call a special meeting.

          G. Subject to the rights of the holders of any series of Preferred
     Stock or any other series or class of stock (excluding Common Stock) set
     forth in the Certificate of Incorporation to elect additional directors
     under specified circumstances or to consent to specific actions taken by
     the Corporation, any action required or permitted to be taken by the
     stockholders of the Corporation must be taken at an annual or special
     meeting of the stockholders and may not be taken by any consent in writing
     by such stockholders.

          H.  Notwithstanding anything contained in this Certificate of
     Incorporation to the contrary, the affirmative vote of the holders of
     shares representing at least 66-2/3% of the voting power of the then
     outstanding voting stock of the Corporation entitled to vote in elections
     of directors generally, voting together as a single class, shall be
     required to amend, repeal or adopt any provisions inconsistent with this
     Article SIXTH.

                                      -9-

     SEVENTH:  The Board of Directors shall have the power, in addition to the
stockholders, to make, alter, or repeal the By-laws of the Corporation.

     EIGHTH:  A director of the Corporation shall not be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the GCL, or (iv) for any
transaction from which the director derived an improper personal benefit.
Neither the amendment nor repeal of this Article EIGHTH, nor the adoption of any
provision of this Certificate of Incorporation inconsistent with this Article
EIGHTH, shall eliminate or reduce the effect of this Article EIGHTH in respect
of any matter occurring, or any cause of action, suit or claim that, but for
this Article EIGHTH, would accrue or arise, prior to such amendment, repeal or
adoption of an inconsistent provision.

     NINTH:  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders are granted subject to this reservation.

interest with which it is coupled is an interest in the stock itself or an
interest in the Corporation generally.  A proxy shall not be revoked by the
death or incapacity of the maker unless, before the vote is counted or the
authority is exercised, written notice of such death or incapacity is given to
the secretary of the Corporation.

     SECTION 2.08.  Notice of Stockholder Business and Nominations.
                    ---------------------------------------------- 

     (A) Annual Meeting of Stockholders.
         ------------------------------ 

         (1) Nominations of persons for election to the Board of Directors of
the Corporation and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (a) by or at the
direction of the Board of Directors pursuant to a resolution adopted by a
majority of the total number of directors which the Corporation at the time
would have if there were no vacancies or (b) by any stockholder of the
Corporation who is entitled to vote at the meeting with respect to the election
of directors or the business to be proposed by such stockholder, as the case may
be, who complies with the notice procedures set forth in clauses (2) and (3) of
paragraph (A) of this Section 2.08 and who is a stockholder of record at the
time such notice is delivered to the secretary of the Corporation as provided
below.

         (2) For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (b) of paragraph (A) (1) of
this Section 2.08, the stockholder must have given timely notice thereof in
writing to the secretary of the Corporation and such business must be a proper
subject for stockholder action under the Delaware General Corporation Law (the
"DGCL").  To be timely, a stockholder's notice shall be delivered to the
secretary of the Corporation at the principal executive office of the
Corporation not less than sixty days nor more than ninety days prior to the
first anniversary of the preceding

                                      -3-

year's annual meeting (or action taken by consent in lieu of annual meeting);
provided, however, that in the event that the date of the annual meeting is
- --------  -------                                                          
advanced by more than 30 days, or delayed by more than 30 days, from such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the ninetieth day prior to such annual meeting and not later
than either the close of business on (a) the tenth day following the day on
which notice of the date of such meeting was mailed or (b) the tenth day
following the day on which public announcement of the date of such meeting is
first made, whichever first occurs in (a) or (b).  Such stockholder's notice
shall set forth (x) as to each person whom the stockholder proposes to nominate
for election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors, or is otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),

a nominee and to serving as a director if elected; (y) as to any other business
that the stockholder proposes to bring before the meeting, a brief description
of the business desired to be brought before the meeting, the reasons for
conducting such business at the meeting and any material interest in such
business of such stockholder and the beneficial owner, if any, on whose behalf
the proposal is made; and (z) as to the stockholder giving the notice and the
beneficial owner, if any, on whose behalf the nomination or proposal is made (i)
the name and address of such stockholder, as they appear on the Corporation's
books, and of such beneficial owner and (ii) the class and number of shares of
the Corporation which are owned beneficially and of record by such stockholder

         (3) Notwithstanding anything in the second sentence of paragraph (A)

directors to be elected to the Board of Directors is increased and there is no
public announcement naming all of the nominees for director or specifying the
size of the increased Board of Directors made by the Corporation at least eighty
days prior to the first anniversary of the preceding year's annual meeting, a
stockholder's notice required by paragraph (A) (2) of this Section 2.08 shall
also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the secretary of
the Corporation at the principal executive offices of the Corporation not later
than the close of business on the tenth day following the day on which such
public announcement is first made by the Corporation.

     (B) Special Meeting of Stockholders.  Only such business shall be conducted
         -------------------------------                                        
at a special meeting of stockholders as shall have been brought before the
meeting pursuant to the Corporation's notice of meeting and in accordance with
these By-laws.  Nominations of persons for election to the Board of Directors
may be made at a special meeting of stockholders at which directors are to be
elected pursuant to the Corporation's notice of meeting (a) by or at the
direction of the Board of Directors or (b) provided that the Board of Directors
has determined that directors shall be elected at such meeting, by any
stockholder of the Corporation who is a stockholder of record at the time of
giving of notice provided for in this Section 2.08, who shall

                                      -4-
<PAGE>
 
be entitled to vote at the meeting and who complies with the notice procedures
set forth in this Section 2.08.  In the event the Corporation calls a special
meeting of stockholders for the purpose of electing one or more directors to the
Board of Directors, any such stockholder may nominate a person or persons (as
the case may be), for election to such position(s) as specified in the
Corporation's notice of meeting, if the stockholder's notice required by
paragraph (A)(2) of this Section 2.08 shall be delivered to the Secretary at the
principal executive offices of the Corporation not earlier than the close of
business on the 90th day prior to such special meeting and not later than the
close of business on the later of the 60th day prior to such special meeting or
the 10th day following the day on which public announcement is first made of the
date of the special meeting and of the nominees proposed by the Board of
Directors to be elected at such meeting.  In no event shall the public
announcement of an adjournment of a special meeting commence a new time period
for the giving of a stockholders notice as described above.

     (C)  General.
          ------- 

         (1) Only persons who are nominated in accordance with the procedures
set forth in this Section 2.08 shall be eligible to serve as directors and only
such business shall be conducted at a meeting of stockholders as shall have been
brought before the meeting in accordance with the procedures set forth in this
Section 2.08.

         (2) Except as otherwise provided by law, the Certificate of
Incorporation or this Section 2.08, the chairman of the meeting shall have the
power and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made in accordance with the procedures set forth
in this Section 2.08 and, if any proposed nomination or business is not in

stockholder's proxy, the inspectors shall make a report in writing of any
challenge or question or matter determined by them, and execute a certificate of

                                ----------------

     SECTION 5.01.  Notice, What Constitutes.  Whenever, under the provisions of
                    ------------------------                                    
the statutes of Delaware or the Certificate of Incorporation or of these By-
laws, notice is required to be given to any director or stockholder, it shall
not be construed to mean personal notice, but such notice may be given in
writing, by mail, addressed to such director or stockholder, at such
stockholder's address as it appears on the records of the Corporation, with
postage thereon prepaid, and such notice shall be deemed to be given at the time
when the same shall be deposited in the United States mail.  Notice to directors
may also be given in accordance with Section 3.09 of Article III hereof.

     SECTION 5.02.  Waivers of Notice.  Whenever any written notice is required
                    -----------------                                          
to be given under the provisions of the Certificate of Incorporation, these By-
laws, or by statute, a waiver thereof in writing, signed by the person or
persons entitled to such notice, whether before or after the time stated
therein, shall be deemed equivalent to the giving of such notice.  Except in the
case of a special meeting of stockholders, neither the business to be transacted
at, nor the purpose of, any regular or special meeting of the stockholders,
directors, or members of a committee of directors need be specified in any
written waiver of notice of such meeting.

     Attendance of a person, either in person or by proxy, at any meeting, shall
constitute a waiver of notice of such meeting, except where a person attends a
meeting for the express purpose of objecting to the transaction of any business
because the meeting was not 

                                      -12-

lawfully called or convened.

     SECTION 5.03.  Exception to Requirements of Notice.  Whenever notice is
                    -----------------------------------                     
required to be given, under any provision of the DGCL or of the Certificate of
Incorporation or these By-laws, to any person with whom communication is
unlawful, the giving of such notice to such person shall not be required and
there shall be no duty to apply to any governmental authority or agency for a
license or permit to give such notice to such person.  Any action or meeting
which shall be taken or held without notice to any such person with whom
communication is unlawful shall have the same force and effect as if such notice
had been duly given.  In the event that the action taken by the Corporation is
such as to require the filing of a certificate under any section of the DGCL,
the certificate shall state, if such is the fact and if notice is required, that
notice was given to all persons entitled to receive notice except such persons
with whom communication is unlawful.

     Whenever notice is required to be given, under any provision of the DGCL or
the Certificate of Incorporation or these By-laws, to any stockholder to whom
(i) notice of two consecutive annual meetings, and all notices of meetings or of
the taking of action by written consent without a meeting to such person during
the period between such two consecutive annual meetings, or (ii) all, and at
least two, payments (if sent by first class mail) of dividends or interest on
securities during a 12 month period, have been mailed addressed to such person
at such stockholder's address as shown on the records of the Corporation and
have been returned undeliverable, the giving of such notice to such person shall
not be required. Any action or meeting which shall be taken or held without
notice to such person shall have the same force and effect as if such notice had
been duly given. If any such person shall deliver to the Corporation a written
notice setting forth such stockholder's then current address, the requirement
that notice be given to such person shall be reinstated. In the event that the
action taken by the Corporation is such as to require the filing of a
certificate under any section of the DGCL, the certificate need not state that
notice was not given to persons to whom notice was not required to be given
pursuant to this section.

                     -------------------------------------

     SECTION 6.01.  Issuance.  Each stockholder shall be entitled to a
                    --------                                          
certificate or certificates for shares of stock of the Corporation owned by such
stockholder upon such stockholder's request therefor.  The stock certificates of
the Corporation shall be numbered and registered in the stock ledger and
transfer books of the Corporation as they are issued.  They shall be signed by
the chairman of the board, the president or a vice president and by the
secretary or an assistant secretary or the treasurer. It shall not be necessary
for any such certificate to bear the 

                                      -13-
<PAGE>
 
corporate seal unless required by law. Any of or all the signatures upon such
certificate may be a facsimile, engraved or printed. In case any officer,
transfer agent or registrar who has signed, or whose facsimile signature has
been placed upon, any share certificate shall have ceased to be such officer,
transfer agent or registrar, before the certificate is issued, it may be issued
with the same effect as if he were such officer, transfer agent or registrar at
the date of its issue.

     SECTION 6.02.  Transfer.  Upon surrender to the Corporation or the transfer
                    --------                                                    
agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignation or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.  No transfer shall be made which would be
inconsistent with the provisions of Article 8, Title 6 of the Delaware Uniform
Commercial Code-Investment Securities.

     SECTION 6.03.  Stock Certificates.  Stock certificates of the Corporation
                    ------------------                                        
shall be in such form as provided by statute and approved by the Board of
Directors or by such committee or officer authorized by the Board of Directors
to approve the form of certificate.  The stock record books and the blank stock
certificates books shall be kept by the secretary or by any agency designated by
the Board of Directors for that purpose.

     SECTION 6.04.  Lost, Stolen, Destroyed or Mutilated Certificates.  The
                    -------------------------------------------------      
Board of Directors may direct a new certificate or certificates to be issued in
place of any certificate or certificates theretofore issued by the Corporation
alleged to have been lost, stolen or destroyed, upon the making of an affidavit
of that fact by the person claiming the certificate of stock to be lost, stolen
or destroyed.  When authorizing such issue of a new certificate or certificates,
the Board of Directors may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
certificate or certificates, or such stockholder's legal representative, to
advertise the same in such manner as it shall require and/or to give the
Corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the Corporation with respect to the certificate alleged
to have been lost, stolen or destroyed.

     SECTION 6.05.  Record Holder of Shares.  The Corporation shall be entitled
                    -----------------------                                    
to recognize the exclusive right of a person registered on its books as the
owner of shares to receive dividends, and to vote as such owner, and to hold
liable for calls and assessments a person registered on its books as the owner
of shares, and shall not be bound to recognize any equitable or other claim to
or interest in such share or shares on the part of any other person, whether or
not it shall have express or other notice thereof, except as otherwise provided
by the laws of Delaware.

     SECTION 6.06.  Determination of Stockholders of Record.  In order that the
                    ---------------------------------------                    

                                      -14-
<PAGE>
 
Corporation may determine the stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, the Board of Directors
may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted by the Board of Directors, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting.  If no record date is fixed by the Board of Directors, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held.  A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     In order that the Corporation may determine the stockholders entitled to
receive payment of any dividend or other distribution or allotment of any rights
of the stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty days prior to such action.
If no record date is fixed, the record date for determining stockholders for any
such purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.


                                  ARTICLE VII

                   INDEMNIFICATION OF DIRECTORS, OFFICERS AND
                        OTHER AUTHORIZED REPRESENTATIVES
                    ----------------------------------------------

     SECTION 7.01.  Indemnification of Authorized Representatives in Third Party
                    ------------------------------------------------------------
Proceedings.  The Corporation shall indemnify any person who was or is an
- -----------                                                              
authorized representative of the Corporation, and who was or is a party, or is
threatened to be made a party to any third party proceeding, by reason of the
fact that such person was or is an authorized representative of the Corporation,
against expenses, judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such third
party proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in, or not opposed to, the best interests of the
Corporation and, with respect to any criminal third party proceeding, had no
reasonable cause to believe such conduct was unlawful.  The termination of any
third party proceeding by judgment, order, settlement, indictment, conviction or
upon a plea of nolo contendere or its equivalent, shall not of itself create a
presumption that the authorized representative did not act in good faith and in
a manner which such person reasonably believed to be in or not opposed to, the
best interests of the Corporation, and, with respect to any criminal third party
proceeding, had reasonable cause to believe that such conduct

                                      -15-
<PAGE>
 
was unlawful.

     SECTION 7.02.  Indemnification of Authorized Representatives in Corporate
                    ----------------------------------------------------------
Proceedings.  The Corporation shall indemnify any person who was or is an
- -----------                                                              
authorized representative of the Corporation and who was or is a party or is
threatened to be made a party to any corporate proceeding, by reason of the fact
that such person was or is an authorized representative of the Corporation,
against expenses actually and reasonably incurred by such person in connection
with the defense or settlement of such corporate action if such person acted in
good faith and in a manner reasonably believed to be in, or not opposed to, the
best interests of the Corporation, except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such corporate proceeding was pending
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such authorized representative is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

     SECTION 7.03.  Mandatory Indemnification of Authorized Representatives.  To
                    -------------------------------------------------------     
the extent that an authorized representative of the Corporation has been
successful on the merits or otherwise in defense of any third party or corporate
proceeding or in defense of any claim, issue or matter therein, such person
shall be indemnified against expenses actually and reasonably incurred by such
person in connection therewith.

     SECTION 7.04.  Determination of Entitlement to Indemnification.  Any
                    -----------------------------------------------      
indemnification under Section 7.01, 7.02 or 7.03 of this Article (unless ordered
by a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the authorized representative
is proper in the circumstances because such person has either met the applicable
standard of conduct set forth in Section 7.01 or 7.02 or has been successful on
the merits or otherwise as set forth in Section 7.03 and that the amount
requested has been actually and reasonably incurred.  Such determination shall
be made:

     (1) By the Board of Directors by a majority of a quorum consisting of
directors who were not parties to such third party or corporate proceeding, or

     (2) If such a quorum is not obtainable, or, even if obtainable, a majority
vote of such a quorum so directs, by independent legal counsel in a written
opinion, or

     (3)  By the stockholders.

     SECTION 7.05.  Advancing Expenses.
                    ------------------ 
     (1) Expenses actually and reasonably incurred in defending a third party or

                                      -16-
<PAGE>
 
corporate proceeding shall be paid on behalf of a director or other authorized
representative by the Corporation in advance of the final disposition of such
third party or corporate proceeding upon receipt of an undertaking by or on
behalf of the director or other authorized representative to repay such amount
if it shall ultimately be determined that such person is not entitled to be
indemnified by the Corporation as authorized in this Article.

     (2) The financial ability of any director or other authorized
representative to make a repayment contemplated by this Section 7.05 shall not
be a prerequisite to the making of an advance.

     SECTION 7.06.  Definitions.  For purposes of this Article VII:
                    -----------

Corporation, or a person serving at the request of the Corporation as a
director, officer, or trustee, of another corporation, partnership, joint
venture, trust or other enterprise;

     (2) "corporation" shall include, in addition to the resulting corporation,
any constituent corporation (including any constituent of a constituent)
absorbed in a consolidation of merger which, if its separate existence had
continued, would have had power and authority to indemnify its directors,
officers, employees or agents, so that any person who is or was a director,
officer, employee or agent of such constituent corporation, or is or was serving
at the request of such constituent corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, shall stand in the same position under the provisions of this
Article with respect to the resulting or surviving corporation as such person
would have with respect to such constituent corporation if its separate
existence had continued;

     (3) "corporate proceeding" shall mean any threatened, pending or completed
action or suit by or in the right of the Corporation to procure a judgment in
its favor or investigative proceeding by the Corporation;

     (4) "criminal third party proceeding" shall include any action or
investigation which could or does lead to a criminal third party proceeding;

     (5) "expenses" shall include attorneys' fees and disbursements;

     (6) "fines" shall include any excise taxes assessed on a person with
respect to an employee benefit plan;

     (7) "not opposed to the best interests of the Corporation" shall include
actions 

                                      -17-

     (11) "third party proceeding" shall mean any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative,
or investigative, other than an action by or in the right of the Corporation.

     SECTION 7.07.  Insurance.  The Corporation may purchase and maintain
                    ---------                                            
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another Corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
such person and incurred by such person in any such capacity, or arising out of
such person's status as such, whether or not the Corporation would have the
power or the obligation to indemnify such person against such liability under
the provisions of this Article.

     SECTION 7.08.  Scope of Article.  The indemnification of authorized
                    ----------------

which those seeking indemnification or advancement of expenses may be entitled
under any statute, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in an official capacity and as to action in another
capacity.  The indemnification and advancement of expenses provided by or

authorized representative of the Corporation shall be deemed to be doing so in
reliance upon rights of indemnification provided by this Article, with the same
effect as if such person and the Corporation entered into a binding contract
under which the Corporation agreed to provide the indemnification provided by
this Article VII.

Corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board of Directors at any regular or special
meeting, pursuant to law.  Dividends may be paid in cash, in property, or in
shares of the capital stock of the Corporation, subject to the provisions of the
Certificate of Incorporation.  Before payment of any dividend, there may be set
aside out of any funds of the Corporation available for dividends such sum or
sums as the directors from time to time, in their absolute discretion, think
proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the directors shall think conducive to the interest of
the Corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

     SECTION 8.02.   Contracts.  Except as otherwise provided in these By-laws,
                     ---------                                                 
the Board of Directors may authorize any officer or officers including the
chairman and vice chairman of the Board of Directors, or any agent or agents, to
enter into any contract or to execute or deliver any instrument on behalf of the
Corporation and such authority may be general or confined to specific instances.

     SECTION 8.03.  Checks.  All checks, notes, bills of exchange or other
                    ------

     SECTION 8.04.  Corporate Seal.  The corporate seal shall have inscribed
                    --------------                                          
thereon the name of the Corporation, the year of its organization and the words
"Corporate Seal, Delaware".  The seal may be used by causing it or a facsimile
thereof to be impressed or affixed or in any other manner reproduced.

     SECTION 8.05.  Deposits.  All funds of the Corporation shall be deposited

companies, or other depositories as the Board of Directors may approve or
designate, and all such funds shall be withdrawn only upon checks signed by such
one or more officers or employees as the Board of Directors shall from time to
time determine.

     SECTION 8.06.  Corporate Records.  Every stockholder shall, upon written

demand under oath stating the purpose thereof, have a right to examine, in
person or by agent or attorney, during the usual hours for business, for any
proper purpose, the stock ledger, books or records of account, and records of
the proceedings of the stockholders and directors, and make copies or extracts
therefrom.  A proper purpose shall mean a purpose reasonably related to such
person's interest as a stockholder.  In every instance where an attorney or
other agent shall be the 

                                      -19-
<PAGE>
 
person who seeks the right to inspection, the demand under oath shall be
accompanied by a power of attorney or such other writing which authorizes the
attorney or other agent to so act on behalf of the stockholder. The demand under
oath shall be directed to the Corporation at its registered office in Delaware
or at its principal place of business. Where the stockholder seeks to inspect
the books and records of the Corporation, other than its stock ledger or list of
stockholders, the stockholder shall first establish (1) compliance with the
provisions of this section respecting the form and manner of making demand for
inspection of such document; and (2) that the inspection sought is for a proper
purpose. Where the stockholder seeks to inspect the stock ledger or list of
stockholders of the Corporation and has complied with the provisions of this
section respecting the form and manner of making demand for inspection of such
documents, the burden of proof shall be upon the Corporation to establish that
the inspection sought is for an improper purpose.

     Any director shall have the right to examine the Corporation's stock
ledger, a list of its stockholders and its other books and records for a purpose

summarily order the Corporation to permit the director to inspect any and all
books and records, the stock ledger and the stock list and to make copies or
extracts therefrom.  The court may, in its discretion, prescribe any limitations
or conditions with reference to the inspection, or award such other and further
relief as the court may deem just and proper.

to, rescinded or repealed at any meeting of the Board of Directors or of the
stockholders, provided that notice of the proposed change was given in the
              --------                                                    
notice of the meeting and, in the case of the Board of Directors, in a notice
given no less than twenty-four hours prior to the meeting; provided, however,
                                                           ----------------- 
that in the case of amendments by stockholders, notwithstanding any other
provisions of these By-laws or any provision of law which might otherwise permit
a lesser vote or no vote, but in addition to any affirmative vote of the holders
of any series of Preferred Stock or any other series or class of stock set forth
in the Certificate of Incorporation which is required by law, the Certificate of
Incorporation or these By-laws, the affirmative vote of the holders of at least
66 2/3% of the voting power of the then outstanding shares of the Corporation

by proxy, voting together as a single class, shall be required to alter, amend
or repeal Sections 2.03, 2.08, 2.10, 3.02, 3.03, 3.05, 8.07 and Article VII of

     Unisource Worldwide, Inc.
     825 Duportail Road
     Wayne, Pennsylvania  19087

     Re:   Issuance of Shares Pursuant to Registration Statement on Form S-4
           -----------------------------------------------------------------

     Gentlemen:

     We have acted as counsel to Unisource Worldwide, Inc., a Delaware
     corporation (the "Company"), in connection with the preparation and filing
     with the Securities and Exchange Commission under the Securities Act of
     1933, as amended (the "Act"), of a Registration Statement on Form S-4 (the
     "Registration Statement") relating to the offering by the Company of an
     aggregate of 5,000,000 shares (the "Shares") of the Company's Common Stock,
     $.001 par value per share, which may be issued from time to time in
     connection with the acquisition by the Company of other businesses, assets
     or securities.

     In so acting, we have examined originals, or copies certified or otherwise
     identified to our satisfaction, of such documents, records, certificates
     and other instruments of the Company as in our judgment are necessary or
     appropriate for purposes of this opinion.  We have assumed that (i) the
     issuance of such Shares will have been duly authorized, the Shares will
     have been reserved for issuance, and certificates evidencing the same will
     have been duly executed and delivered, against receipt of the consideration
     approved by the Board of Directors of the Company or a committee thereof
     which will be not less than the par value thereof, and (ii) the Shares will
     be issued in compliance with applicable federal and state securities laws.

     Based upon the foregoing, we are of the opinion that the Shares, when and
     to the extent issued and sold by the Company, will be duly authorized,
     validly issued, fully paid and non-assessable.
