<PAGE>   2

                          AGREEMENT AND PLAN OF MERGER


        THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and
entered into as of September 3, 1996, by and among DIAGNOSTIC IMAGING, INC.
("DII"), a Florida corporation having its principal office located in
Jacksonville, Florida; PSS MERGER CORP. ("Merger Corp."), a Florida corporation
having its principal office located in Jacksonville, Florida; and PHYSICIAN
SALES & SERVICE, INC. ("PSS"), a Florida corporation having its principal
office located in Jacksonville, Florida.


                                    PREAMBLE

        The Boards of Directors of PSS, Merger Corp., a wholly owned subsidiary
of PSS, and DII are of the opinion that the transactions described herein are
in the best interests of the parties and their respective shareholders.  This
Agreement provides for the acquisition of DII by PSS pursuant to the merger of
Merger Corp. with and into DII.  At the Effective Time of such merger, the
outstanding shares of the capital stock of DII shall be converted into the
right to receive shares of the common stock of PSS (except as provided herein).
As a result, shareholders of DII shall become shareholders of PSS and DII shall
continue to conduct its business and operations as a wholly owned subsidiary of
PSS.  The transactions described in this Agreement are subject to the approvals
of the shareholders of DII and the satisfaction of certain other conditions
described in this Agreement.  It is the intention of the parties to this
Agreement that the Merger shall qualify (i) as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code for federal income tax
purposes, and (ii) for treatment as a pooling of interests for accounting
purposes.

        Certain terms used in this Agreement are defined in Section 11.1 of
this Agreement.

        NOW, THEREFORE, in consideration of the above and the mutual
warranties, representations, covenants and agreements set forth herein, the
parties agree as follows:


                                   ARTICLE 1
                        TRANSACTIONS AND TERMS OF MERGER

        1.1     Merger.  Subject to the terms and conditions of this Agreement,
at the Effective Time, Merger Corp. shall be merged with and into DII in
accordance with the applicable provisions of the FBCA (the "Merger").  DII
shall be the Surviving Corporation resulting from the Merger and shall become a
wholly owned Subsidiary of PSS and shall continue to be governed by the Laws of
the State of Florida.  The Merger shall be consummated pursuant to the terms of
this Agreement, which has been approved and adopted by the respective Boards of
Directors of DII, Merger Corp. and PSS and the shareholders of DII and Merger
Corp.

        1.2     Time and Place of Closing.  The closing (the "Closing") will
take place at 10:00 A.M. on a date to be specified by the parties (the "Closing
Date"), which (subject to the satisfaction or waiver of the conditions set
forth in Sections 9.2 and 9.3) shall be no later than the second business day
after the satisfaction of the conditions set forth in Section 9.1.  The place
of Closing shall be at the offices of Alston & Bird, One Atlantic Center, 1201
West Peachtree Street, Atlanta, Georgia 30309-3424, or such other place as may
be mutually agreed upon by the Parties.
<PAGE>   3

        1.3     Effective Time.  Subject to the provisions of this Agreement,
the parties shall file Articles of Merger executed in accordance with the
relevant provisions of the FBCA and shall make all other filings or recordings
required under the FBCA as soon as practicable on or after the Closing Date.
The Merger and other transactions contemplated by this Agreement shall become
effective on the date and at the time the Articles of Merger reflecting the
Merger become effective with the Secretary of State of the State of Florida
(the "Effective Time").


                                   ARTICLE 2
                                TERMS OF MERGER

        2.1     Charter.  The Articles of Incorporation of DII in effect
immediately prior to the Effective Time shall be amended and restated,
effective at the Effective Time, in a manner satisfactory to PSS.  The Articles
of Incorporation of DII, as so amended and restated, shall be the Articles of
Incorporation of the Surviving Corporation until otherwise amended or repealed.

        2.2     Bylaws.  The Bylaws of Merger Corp. in effect immediately prior
to the Effective Time shall be the Bylaws of the Surviving Corporation until
otherwise amended or repealed.

        2.3     Tax-Free Reorganization.  The parties intend to adopt this
Agreement as a tax-free plan of reorganization under Section 368(a) of the
Internal Revenue Code.


                                   ARTICLE 3
                          MANNER OF CONVERTING SHARES

        3.1     Conversion of Shares.  Subject to the provisions of this
Article 3, at the Effective Time, by virtue of the Merger and without any
action on the part of the Parties or the shareholders of any of the Parties,
the shares of the constituent corporations of the Merger shall be converted as
follows:

                (a)  Each share of Merger Corp. Common Stock issued and
outstanding at the Effective Time shall cease to be outstanding and shall be
converted into one share of DII Common Stock.

                (b)  Each share of DII Common Stock (excluding treasury shares
and excluding shares held by shareholders who perfect their statutory
dissenters' rights as provided in Section 3.4 of this Agreement) issued and
outstanding at the Effective Time shall cease to be outstanding and shall be
converted into and exchanged for: (i) the right to receive that number of
shares of PSS Common Stock obtained by dividing the Common Stock Per Share
Purchase Price by the Base Period Trading Price, and (ii) a contingent right to
receive that portion of the Escrow Shares, that are attributable to each such
share of DII Common Stock, that are deposited into escrow by PSS pursuant to
Section 4.3 of this Agreement.  The sum of clause (i) and (ii) of the preceding
sentence is the "Common Stock Exchange Ratio."  The Base Period Trading Price
is defined to mean the average of the daily closing prices for the shares of
PSS Common Stock for the five (5) consecutive trading days on which such shares
are actually traded as over-the-counter securities and quoted on the Nasdaq
National Market (as reported by The Wall Street Journal or, if not reported
thereby, any other authoritative source) ending at the close of trading on the
second trading day immediately prior to the Closing Date; provided, that for
purposes of this calculation, the Base Period Trading Price shall be deemed to
equal (i) $19.25 in the event the Base Period Trading Price is greater than
$19.25 and (ii) $15.75 in the event the Base Period Trading Price is less than
$15.75 (collectively, $19.25 and $15.75 are referred to as the "Base Period
Trading Price Limitations").
<PAGE>   4

                (c)  Subject to adjustment as set forth below, the Aggregate
Purchase Price shall equal $13,000,000, (i) plus or minus the Book Value
Adjustment, if any, (ii) minus any expenses incurred by DII or on DII's behalf
in connection with the transactions contemplated hereunder in excess of
$200,000, determined in accordance with Section 11.2 hereof.  The Aggregate
Purchase Price shall be (i) increased by the amount by which the shareholders'
equity of DII as of June 30, 1996, as determined pursuant to the audit of
Arthur Andersen LLP to be conducted as set forth in Section 8.1 hereof, is
greater than $4,343,110 (shareholders' equity of DII as reflected on the June
30, 1996 unaudited balance sheet), and (ii) decreased by the amount by which
the shareholders' equity of DII as of June 30, 1996, as determined pursuant to
the audit of Arthur Andersen LLP to be conducted as set forth in Section 8.1
hereof, is less than $4,343,110 (the "Book Value Adjustment").  The Aggregate
Purchase Price shall also be increased dollar for dollar in an amount equal to
any reduction below $6,200,000 in the Funded Debt of DII as reflected on the
balance sheet of DII as of June 30, 1996 included in the Financial Statements,
provided that such reductions shall not be the result of any increase in
accounts payable or decrease in working capital.

        3.2     Anti-Dilution Provisions. In the event DII or PSS changes the
number of shares of DII Common Stock or PSS Common Stock, respectively, issued
and outstanding prior to the Effective Time as a result of a stock split, stock
dividend, combination of shares or similar recapitalization with respect to
such stock (an "Anti-Dilution Event") and the record date therefor (in the case
of a stock dividend) or the effective date thereof (in the case of a stock
split, share exchange or similar recapitalization for which a record date is
not established) shall be prior to the Effective Time, the Common Stock
Exchange Ratio shall be proportionately adjusted to insure that holders of DII
Common Stock shall receive PSS Common Stock having the same value as they would
have received prior to the Anti-Dilution Event.  In the event PSS has an
Anti-Dilution Event and the record date therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split, share
combination, share exchange or similar recapitalization for which a record date
is not established) shall be prior to the Effective Time, the Base Period
Trading Price shall be adjusted to appropriately adjust the ratio under which
shares of DII Common Stock will be converted into shares of PSS Common Stock
pursuant to Section 3.1(b) or Section 3.6, as the case may be, of this
Agreement to insure that holders of DII Common Stock shall receive PSS Common
Stock having the same value as they would have received prior to the Anti-
Dilution Event.

        3.3     Shares Held by DII.  Each share of DII Capital Stock held in
treasury by DII shall be canceled and retired at the Effective Time and no
consideration shall be issued in exchange therefor.

        3.4     Dissenting Shareholders.  Any holder of shares of DII Capital
Stock who perfects its dissenters' rights in accordance with and as
contemplated by Section 607.1320 of the FBCA shall be entitled to receive the
value of such shares in cash from DII after the Effective Time as determined
pursuant to such provision of Law; provided, that no such payment shall be made
to any dissenting shareholder unless and until such dissenting shareholder has
complied with the applicable provisions of the FBCA and surrendered to DII the
certificate or certificates representing the shares for which payment is being
made.  In the event that a dissenting shareholder of DII fails to perfect, or
effectively withdraws or loses, its right to appraisal and of payment for its
shares, PSS shall issue and deliver the consideration to which such holder of
shares of DII Capital Stock is entitled under this Article 3 (without interest)
upon surrender by such holder of the certificate or certificates representing
such shares held by such holder.

        3.5     Fractional Shares.  No certificates representing fractional
shares of PSS Common Stock will be issued as a result of the Merger.  Each
holder of shares of DII Common Stock exchanged pursuant to the Merger who would
otherwise have been entitled to receive a fraction of a share of PSS Common
Stock shall receive, in lieu thereof, cash (without interest) in an amount
equal to such fractional part of a

<PAGE>   5

share of PSS Common Stock multiplied by the Base Period Trading Price.  No such
holder will be entitled to dividends, voting rights, or any other rights as a
shareholder in respect of any fractional shares.

        3.6     Issuance of Additional Shares.  Additional shares of DII Common
Stock may be issued in accordance with the provisions of Section 2.6 of that
certain Reorganization Agreement dated December 31, 1995 by and among DII,
American Medical Diagnostic Imaging, Inc., B&B X-Ray, Inc., Kings Diagnostic
Imaging, Inc., United X-Ray Company, Inc. and all of the shareholders of DII
(the "Reorganization Agreement"), provided that such additional shares of DII
Common Stock are issued prior to the Effective Time and reflected in the Fully
Diluted Common Equivalents.  All remaining rights of any shareholder to receive
additional shares of DII Common Stock under the Reorganization Agreement or
otherwise shall be terminated by DII prior to the Effective Time.

                                   ARTICLE 4
                               EXCHANGE OF SHARES

        4.1     Exchange Procedures.  Promptly (and in no event more than five
(5) calendar days) after the Effective Time, PSS and DII shall cause the
exchange agent selected by PSS (the "Exchange Agent") to mail to the former
holders of DII Common Stock appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of DII Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent).  After
the Effective Time, each holder of shares of DII Common Stock (other than
shares to be canceled pursuant to Section 3.3 of this Agreement or as to which
statutory dissenters' rights have been perfected as provided in Section 3.4 of
this Agreement) issued and outstanding at the Effective Time shall surrender
the certificate or certificates representing such shares to the Exchange Agent
and shall promptly upon surrender thereof receive in exchange therefor the
consideration provided in Section 3.1 of this Agreement.  To the extent
required by Section 3.5 of this Agreement, each holder of shares of DII Common
Stock issued and outstanding at the Effective Time also shall receive, upon
surrender of the certificate or certificates representing such shares, cash in
lieu of any fractional share of PSS Common Stock to which such holder may be
otherwise entitled (without interest).  PSS shall not be obligated to deliver
the consideration to which any former holder of DII Common Stock is entitled as
a result of the Merger until such holder surrenders his certificate or
certificates representing the shares of DII Common Stock for exchange as
provided in this Section 4.1 or such holder provides an appropriate affidavit
regarding loss of such certificate and an indemnification for loss in favor of
PSS.  The certificate or certificates of DII Common Stock so surrendered shall
be duly endorsed as the Exchange Agent may require.

        4.2     Rights of Former DII Shareholders.  At the Effective Time, the
stock transfer books of DII shall be closed and no transfer of DII Common Stock
by any such holder shall thereafter be made or recognized.  Until surrendered
for exchange in accordance with the provisions of Section 4.1 of this
Agreement, each certificate theretofore representing shares of DII Common Stock
(other than shares to be canceled pursuant to Sections 3.3 and 3.4 of this
Agreement) shall from and after the Effective Time represent for all purposes
only the right to receive the consideration provided in Sections 3.1, 3.5 and
3.6 of this Agreement in exchange therefor.  To the extent permitted by Law,
former shareholders of record of DII shall be entitled to vote after the
Effective Time at any meeting of PSS shareholders the number of whole shares of
PSS Common Stock into which their respective shares of DII Common Stock are
converted, regardless of whether such holders have exchanged their certificates
representing DII Common Stock for certificates representing PSS Common Stock in
accordance with the provisions of this Agreement.  Whenever a dividend or other
distribution is declared by PSS on the PSS Common Stock, the record date for
which is at or after the Effective Time, the declaration shall include
dividends or other distributions on all shares issuable pursuant to this
Agreement, but no dividend or other distribution payable to the holders of
record of PSS Common Stock as of any time subsequent to the Effective Time
shall be delivered to the holder of any certificate representing shares of DII
Common Stock issued and outstanding at the Effective Time until such holder
surrenders such certificate for exchange as provided in Section 4.1 of this
Agreement.  However, upon surrender of such certificate, both the PSS Common
Stock certificate (together with all such undelivered dividends or other
distributions without interest) and any undelivered cash payments to be paid
for fractional share interests (without interest) shall be delivered and paid
with respect to each share represented by such certificate.

        4.3  Escrow Shares.  At the Effective Time, and pursuant to the terms
of the Escrow Agreement attached hereto as Exhibit 4.3, PSS shall issue an
aggregate number of shares of PSS Common Stock equal to the sum of (A) with
respect to the specific indemnity set forth in Section 2.3 of the Escrow
Agreement, the aggregate dollar amount of the specific indemnity items to be
set forth in the Escrow Agreement as

<PAGE>   7

determined pursuant to Section 8.1 hereof, divided by the Base Period Trading
Price, and (B) with respect to the general indemnity set forth in Section 2.2 of
the Escrow Agreement, five percent (5%) of the Aggregate Purchase Price, divided
by the Base Period Trading Price.


                                   ARTICLE 5

its Subsidiaries is duly qualified or licensed to transact business as a
foreign corporation and is in good standing in all jurisdictions where the
character of its Assets or the nature or conduct of its business requires it to

delivery and performance of this Agreement have been duly authorized by all
necessary corporate action of DII, other than the meeting (or written consent)

that are cancelable at will or upon 30 days' notice or less, (i) each of the
Contracts described in this Section 5.19 is in full force and effect on the

        5.21    Benefit Plans.

                (a)  Schedule 5.21.1 lists (i) every pension, retirement,
profit-sharing, deferred compensation, stock option, employee stock ownership,
severance pay, vacation, bonus or other incentive plan, any other written or
unwritten employee program, arrangement, agreement or understanding, whether
arrived at through collective bargaining or otherwise; (ii) any medical,
vision, dental or other health plan, and any life insurance plan; or (iii) any
other employee benefit plan or fringe benefit plan, including, without

3(3) of ERISA, currently or expected to be adopted, maintained by, sponsored in
whole or in part by, or contributed to by DII or any

<PAGE>   17

of its Subsidiaries or any entity aggregated therewith under Internal Revenue
Code Sections 414(b) or 414(c) for the benefit of employees, former employees,
retirees, directors, independent contractors, spouses or dependents of any of
the foregoing or any other beneficiaries and under which such employees,
retirees, dependents, spouses, directors, independent contractors, or other
beneficiaries are eligible to participate (collectively, the "Benefit Plans").
Any Benefit Plan that is an "employee pension benefit plan," as that t 3(2) of
ERISA, or an "employee welfare benefit plan" as that term is defined in Section
3(1) of ERISA, is referred to herein as an "ERISA Plan."  On or after September
26, 1980, neither DII nor any of its Subsidiaries or any entity aggregated
therewith under Internal Revenue Code Section 414(b) or 414(c) have had an
"obligation to contribute" (as defined in ERISA Section 4212) to a
"multiemployer plan" (as defined in ERISA Sections 4001(a)(3) and 3(37)(A))
("Multiemployer Plan"). Except as disclosed on Schedule 5.21, neither DII nor
any of its Subsidiaries have incurred, nor is reasonably expected to incur prior
to the Closing Date, any liability under Title I or Title IV of ERISA or under
Internal Revenue Code Section 412 other than funding obligations and claims for
benefits in accordance with ERISA. All Liabilities arising out of or related to
Benefit Plans and ERISA Plans of DII and of its ERISA Affiliates are reflected
in the Financial Statements in accordance with GAAP.

                (b)  True, correct and complete copies of all written Benefit
Plans, as currently in effect (or as otherwise requested by PSS), listed on
Schedule 5.21.1 and all trust agreements or other funding arrangements,
including insurance contracts, all amendments thereto and, where applicable,
with respect to any such plans or plan amendments, the most recent determination
letters issued by the IRS, all advisory opinions issued by the United States
Department of Labor after December 31, 1974, the annual reports or returns,
audited or unaudited financial statements, actuarial valuations, and summary
annual reports for the most recent three plan years, the most recent summary
plan descriptions and any Material modifications thereto have been made
available to PSS.

                (c)  Except as listed on Schedule 5.21.2, all of the Benefit
Plans and the related trusts subject to ERISA comply with and have been
administered in all Material respects in compliance with the provisions of
ERISA, all provisions of the Internal Revenue Code relating to qualification
and tax exemption under Internal Revenue Code Section 401(a) and 501(a) or
otherwise applicable to secure intended tax consequences, and all other
applicable laws, rules and regulations and collective bargaining agreements in
all Material respects.  Except as listed on Schedule 5.21.2, all governmental
approvals for the Benefit Plans have been obtained, including, but not limited
to, timely determination letters on the qualification of the ERISA Plans and
tax exemption of related trusts, as applicable under the Internal Revenue Code,
and all such governmental approvals continue in full force and effect.  Neither
DII, nor any of its Subsidiaries, nor any administrator or fiduciary of any
such Benefit Plan (or agent of any of the foregoing) has engaged in any
transaction or acted or failed to act in any manner which could subject any
such entity to any direct or indirect liability (by indemnity or otherwise) for
a breach of any fiduciary, co-fiduciary or other duty under ERISA.  No oral or
written representation or communication with respect to any aspect of the
Benefit Plans has been made to employees of DII or any of its Subsidiaries or
any of their respective predecessors prior to or on the Closing Date that is
not in accordance with the written or otherwise preexisting terms and
provisions of such Benefit Plans in effect immediately prior to the Closing
Date.  There are no unresolved claims or disputes under the terms of, or in
connection with, the Benefit Plans and no action, legal or otherwise, has been
commenced with respect to any claim other than processing of claims in the
ordinary course of business..

                (d)  All annual reports or returns, audited or unaudited
financial statements, actuarial valuations, summary annual reports and summary
plan descriptions issued with respect to the Benefit Plans are correct and
accurate in all Material respects.
<PAGE>   18

                (e)  Since December 31, 1974, no "party in interest" (as
defined in Section 3(14) of ERISA) or "disqualified person" (as defined in
Section 4975(e)(2) of the Internal Revenue Code) of any ERISA Plan has engaged
in any "prohibited transaction" (within the meaning of Section 4975(c) of the
Internal Revenue Code or Section 406 of ERISA).

                (f)  No Liability exists and no event that could result in a
Liability has occurred with respect to any Benefit Plan that individually or in
the aggregate could have a Material Adverse Effect on DII or any of its
Subsidiaries.

                (g)  Neither DII nor any of its Subsidiaries have maintained,
or currently maintain, a Benefit Plan providing welfare benefits (as defined in
ERISA Section 3(1)) to employees after retirement or other separation of
service except to the extent required under Part 6 of Title I of ERISA and
Internal Revenue Code Section 4980B(f).

                (h)  Except as set forth on Schedule 5.21.3, the consummation
of the transactions contemplated by this Agreement will not entitle any current
or former employee of DII, any of its Subsidiaries or any of their respective
predecessors whose employment is not terminated as a result of such
transactions, to severance pay, unemployment compensation or any similar
payment, and will not accelerate the time of payment or vesting, or increase
the amount, of compensation due any such employee or former employee.

                (i)  All Benefit Plans subject to Section 4980B of the Internal
Revenue Code or Part 6 of Title I of ERISA, or both, have been maintained in
compliance in all Material respects with the requirements of such laws and any
regulations (proposed or otherwise) issued thereunder.

        5.22    Remuneration.  Schedule 5.22 contains a complete and accurate
schedule of the direct compensation (including wages, salaries and actual or
anticipated bonuses), plus a description of other annual benefits not made
available to the other employees generally, to be paid in the current fiscal
year to (i) all of the officers and directors of DII; and (ii) all of the
employees of DII or any of its Subsid iaries who received or will be receiving
in excess of $50,000 during such year. No unpaid salary, other than for the
immediately preceding pay period and other than pursuant to the existing
deferred compensation plans of DII or any of its Subsidiaries is now payable to
any of such officers, directors or employees.

        5.23    Union and Employment Agreements.  Except as set forth on
Schedule 5.23, neither DII nor any of its Subsidiaries is a party to any union
agreement, nor does any such entity have any written or oral agreement that is
not terminable by it at will with any of its officers, directors, employees,
consultants, agents, or any other person performing services therefor, relating
to their employment by or performance of services for any such entity or their
compensation therefor.  To the knowledge of DII and its Subsidiaries, no union
attempts to organize the employees of DII or any of its Subsidiaries have been
made, nor are any such attempts now threatened.  Except as set forth on
Schedule 5.23, neither DII nor any of its Subsidiaries has received notice, or
has any reason to believe, that any of the officers or directors of any such
entity will terminate or contemplates terminating his or her employment
currently or at any time within sixty (60) days of the Closing Date.

        5.24    Interested Transactions.

                (a)  Except as set forth on Schedule 5.24, neither DII nor any
of its Subsidiaries are currently a party to any Contract, loan or other
transaction with any of the following persons, or in which
<PAGE>   19

any of the following persons have any direct or indirect interest (other than as
a shareholder or employee of DII):

                        (i)  Any director, officer or employee of DII or its
        Subsidiaries or any of the shareholders of DII;

                        (ii)  Any of the spouses, parents, siblings, children,
        aunts, uncles, nieces, nephews, in-laws and grandparents of any of the

        in the aggregate no more than 5% of the equity interest).

                (b)  Except as set forth on Schedule 5.24, none of the
shareholders of DII is an employee, consultant, partner, principal, director or
shareholder of any business entity which is engaged in a business which
competes with or is similar to the business of DII or any of its Subsidiaries.

        5.25    Brokers and Finders.  No broker, agent, finder or consultant or
other person has been retained by or on behalf of DII or is entitled to be paid

        6.4     PSS Subsidiaries.  Schedule 6.4 attached hereto is a true and
correct list of each Subsidiary of PSS.  All of the outstanding shares of

        6.5     PSS Documents.  PSS has heretofore furnished the following
documents to DII:

                        (a)  its final Prospectus, dated November 13, 1995,
contained in its Registration Statement on Form S-3 (Registration No.
33-97524);

                        (b)  its Annual Report on Form 10-K for the fiscal
years ended March 29, 1996 and March 30, 1995;

                        (c)  its Proxy Statement dated June 6, 1996.

        Documents (a) - (c) above are collectively referred to herein as the
"PSS Documents."  As of their respective dates, the PSS Documents complied in
all Material respects with all applicable Laws.  Since May 5, 1994, PSS has
filed all reports and statements, together with any amendments required to be
made with respect thereto, that it was required to file with the SEC,
including, but not limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and proxy
statements.  The PSS Documents did not at the time they were filed (or if
amended or superseded by a filing prior to the date of this Agreement, then on
the date of such filing) contain any untrue statement of a material fact or
omit to state a material fact required to be stated in such PSS Document, in
light of the circumstances under which they were made, not misleading.  The
consolidated financial statements (including, in each case, any related notes)
contained in the PSS Documents complied as to form in all material respects
with the applicable published rules and regulations of the SEC with respect
thereto, were prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods involved
(except as may be indicated in the notes to such financial statements or, in
the case of unaudited statements, as permitted by the published rules and
regulations of the SEC with respect thereto) and fairly presented the
consolidated financial position of PSS and its Subsidiaries, taken as a whole,
at the respective dates and the consolidated results of its operations and cash
flows for the periods indicated, except that the unaudited interim financial
statements do not include notes and are subject to normal year end adjustments
which will not, in the aggregate, be Material.  There have been no changes in
PSS' accounting policies and practices between the dates of the PSS Documents
and the date hereof that have had or are likely to have a Material Adverse
Effect on the present or future financial performance of PSS, and no such
change is contemplated as of the date hereof.

        6.6     Absence of Undisclosed Liabilities.  Except as disclosed on
Schedule 6.6, as of the date hereof neither PSS nor any of its Subsidiaries has
any Undisclosed Liabilities in excess of $300,000 in the aggregate, except for
unpaid liabilities and obligations incurred since March 29, 1996, in the
ordinary course of business and not involving Funded Debt.
<PAGE>   22

        6.7     Absence of Certain Changes or Events.  Since March 29, 1996,
except as disclosed on Schedule 6.7, (i) there have been no events, changes or
occurrences which have had, or are reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on PSS, and (ii) neither PSS or any
of its Subsidiaries has taken any action, or failed to take any action, prior
to the date of this Agreement, which action or failure, if taken after the date
of this Agreement, would represent or result in a Material breach or violation
of any of the covenants and agreements of PSS provided in Article 7 of this
Agreement.

        6.8     Legal Proceedings.  There are no outstanding Court Orders or
administrative decisions to which PSS or any of its Subsidiaries is subject,
and there is no Litigation pending or threatened against or relating to PSS or
any of its Subsidiaries or their respective assets or businesses, which if
resolved adversely to PSS would have a Material Adverse Effect on PSS and its
Subsidiaries, taken as a whole.  Neither PSS nor any of its Subsidiaries have
been advised by any attorney representing any such entity that there are any
"loss contingencies" as defined in FASB 5, which would be required by FASB 5 to
be disclosed or accrued in the consolidated financial statements of PSS and
which are not so disclosed or accrued.

        6.9     Brokers and Finders.  No broker, agent, finder or consultant or
other person has been retained by or on behalf of PSS (other than legal or
accounting advisors), or is entitled to be paid based upon any agreements or
understandings made by PSS in connection with the transactions contemplated
hereby.  Neither DII nor PSS shall have any Liability for any broker's fee,
finder's fee, consultant's fee or similar third party remuneration by reason of
any action of PSS.

        6.10    Statements True and Correct.  No statement, certificate,
instrument or other writing furnished or to be furnished by PSS or any
Affiliate thereof to DII pursuant to this Agreement or any other document,
agreement or instrument referred to herein contains or will contain any untrue
statement of Material fact or will omit to state a Material fact necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading.

        6.11    Authority of Merger Corp.  Merger Corp. is a corporation duly
organized, validly existing and in good standing under the Laws of the State of
Florida as a wholly owned Subsidiary of PSS.  The authorized capital stock of
Merger Corp. consists of 1,000 shares of Merger Corp. Common Stock, all of
which is validly issued and outstanding, fully paid and nonassessable and is
owned by PSS free and clear of any Lien. Merger Corp. has the corporate power
and authority necessary to execute, deliver and perform its obligations under
this Agreement and to consummate the transactions contemplated hereby.  The
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated herein, including the Merger, have been duly and
validly authorized by all necessary corporate action in respect thereof on the
part of Merger Corp.  This Agreement represents a legal, valid, and binding
obligation of Merger Corp., enforceable against Merger Corp. in accordance with
its terms.

complete as of the date of this Agreement.  Matters disclosed on each Schedule
shall be deemed disclosed only for purposes of the matters to be disclosed on

nature whatsoever;

                (h)  except in the ordinary course of business and, even if in
the ordinary course of business, then not in an amount to exceed $100,000 in
the aggregate, make or commit to make any capital expenditure, or enter into
any lease of capital equipment as lessee or lessor;

                (i)  not sell any Material asset or make any Material
commitment relating to its assets other than in the ordinary course of
business;

                (j)  not amend the Articles of Incorporation, Bylaws or other
governing instruments of DII or any of its Subsidiaries, or

                (k)  not make any changes in its accounting methods or
practices, except for changes in its tax accounting methods or practices that
may be necessitated by changes in applicable tax laws;
<PAGE>   24

                (l)  except for this Agreement, or pursuant to the exercise of
stock options outstanding as of the date hereof in accordance with their
current terms, issue, sell, pledge, encumber, authorize the issuance of, enter
into any Contract to issue, sell, pledge, encumber, or authorize the issuance
of, or otherwise permit to become outstanding, any additional shares of DII

acquire any such stock, or any security convertible into any such stock, or pay
or declare or agree to pay or declare any dividend with respect to any DII
Capital Stock;

                (m)  other than in the ordinary course of business, not take

Notwithstanding the foregoing, DII shall be entitled, without the consent of
PSS, to take such action as DII deems prudent with respect to the operations of
DII and its Subsidiaries.

        7.2     Conduct of PSS Business.  PSS agrees that from the date hereof
to the Effective Time, except to the extent that DII shall otherwise consent by
an instrument in writing signed on behalf of DII by its President:

                (a)  Operation of Business.  It will operate its business
substantially as presently operated and only in the ordinary course, except
that any business acquisition by PSS or the incurrence of additional debt or
the issuance or sale of equity securities shall be deemed to be in the ordinary
course.

                (b)  No Amendments; Corporate Existence.  Except as previously
disclosed in writing by PSS to DII, it will not, and it will not permit Merger
Corp. to, amend its Articles of Incorporation or By-Laws; and it will maintain

        7.3     Adverse Changes in Condition.  Each Party agrees to give
written notice promptly to the other Party upon becoming aware of the
occurrence or impending occurrence of any event or circumstance relating to it
or any of its Subsidiaries which (i) is reasonably likely to have, individually
or in the aggregate, a Material Adverse Effect on it, or (ii) would cause or
constitute a Material breach of any of its representations, warranties, or
covenants contained herein, and to use its reasonable efforts to prevent or
promptly to remedy the same.

        7.4     Reports.  Each Party and its Subsidiaries shall file all
reports required to be filed by it with Regulatory Authorities between the date
of this Agreement and the Effective Time and shall deliver to the other Party
copies of all such reports promptly after the same are filed.  If financial
statements are contained in any such reports filed with the SEC, such financial
statements will fairly present the consolidated financial position of the
entity filing such statements as of the dates indicated and the consolidated
results of operations, changes in shareholders' equity, and cash flows for the
periods then ended in accordance with GAAP (subject in the case of interim
financial statements to normal recurring year-end adjustments that are not
Material).  As of their respective dates, such reports filed with the SEC
<PAGE>   25

will comply in all Material respects with the securities Laws and will not
contain any untrue statement of a Material fact or omit to state a Material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  Any financial statements contained in any other reports to another
Regulatory Authority shall be prepared in accordance with Laws applicable to
such reports.

                             ADDITIONAL AGREEMENTS

        8.1     Audit by Arthur Andersen LLP.  As soon as practicable after the
date of this Agreement, PSS shall cause Arthur Andersen LLP to conduct an audit
prepared in accordance with GAAP of DII's consolidated statement of income for
the six months ended June 30, 1996 and consolidated balance sheet as of June
30, 1996.  As soon as practicable after the date of this Agreement, DII shall
cause Arthur Andersen LLP to conduct an audit prepared in accordance with GAAP
pro forma combined statements of income for each of the years in the three-year
period ending December 31, 1995 and pro forma combined balance sheets for DII
as of December 31, 1993, 1994 and 1995.  DII shall make available to Arthur
Andersen all financial records and personnel requested in connection with such
audit.  The audits shall be for the purpose of meeting the financial reporting
requirements of the Securities Act of 1933, as amended, and determining the
Book Value Adjustment, if any, and the specific escrow items and amounts as
provided in Section 2.3 of the Escrow Agreement, the form of which is attached
hereto as Exhibit 4.3.  The Parties shall use their best efforts to identify,
determine and agree upon the specific escrow items and amounts in accordance
with the audits.  The expenses for the audits pursuant to this Section 8.1
shall be paid for as provided in Section 11.2 hereof.

        8.2     Applications; Antitrust Notification.  PSS shall promptly
prepare and file, and DII shall cooperate in the preparation and, where
appropriate, filing of, applications with all Regulatory Authorities having
jurisdiction over the transactions contemplated by this Agreement seeking the
requisite Consents necessary to consummate the transactions contemplated by
this Agreement.  Each of the Parties will promptly file with the United States
Federal Trade Commission and the United States Department of Justice the
notification and report form required for the transactions contemplated hereby
and any supplemental or additional information which may reasonably be
requested in connection therewith pursuant to the HSR Act and will comply in
all Material respects with the requirements of the HSR Act.

        8.3     Filings with State Offices.  Upon the terms and subject to the
conditions of this Agreement, DII and Merger Corp. shall execute and file the
Articles of Merger with the Secretary of State of the State of Florida in
connection with the Closing.

        8.4     Agreement as to Efforts to Consummate.  Subject to the terms
and conditions of this Agreement, each Party agrees to use, and to cause its
Subsidiaries to use, its reasonable best efforts to take, or cause to be taken,
all actions, and to do, or cause to be done, all things necessary, proper, or
advisable under applicable Laws to consummate and make effective, as soon as
practicable after the date of this Agreement, the transactions contemplated by
this Agreement, including using its reasonable best efforts to lift or rescind
any Order adversely affecting its legal ability to consummate the transactions
contemplated herein and to cause to be satisfied the conditions referred to in
Article 9 of this Agreement; provided, that nothing herein shall preclude
either Party from exercising its rights under this Agreement.  Each Party shall
use, and shall cause each of its Subsidiaries to use, its reasonable efforts to
obtain all Consents necessary or desirable for the consummation of the
transactions contemplated by this Agreement.
<PAGE>   26

        8.5     Investigation and Confidentiality.

                (a)  Prior to the Effective Time, each party shall keep the
other party advised of all Material developments relevant to its business and
to consummation of the Merger.  DII shall provide PSS open and exclusive access
to DII, its records and employees in order for PSS to make or cause to be made
such investigation of the business and properties of DII and its Subsidiaries
and of its financial and legal condition as PSS reasonably requests, provided
that such investigation shall not interfere unnecessarily with normal
operations.  No investigation by a Party shall affect the representations and
warranties of the other Party.

                (b)  Each Party shall, and shall cause its advisers and agents
to, maintain the confidentiality of all confidential information not otherwise
in the public domain furnished to it by the other Party concerning its and its
Subsidiaries' businesses, operations, customers and financial positions and
shall not use such information for any purpose except in furtherance of the
transactions contemplated by this Agreement.  If this Agreement is terminated
prior to the Effective Time, each Party shall promptly return or certify the
destruction of all documents and copies thereof, and all work papers containing
confidential information received from the other Party.

               (c)  Each Party agrees to give the other Party notice as soon
as practicable after any determination by it of any fact or occurrence relating
to the other Party which it has discovered through the course of its
investigation and which represents, or is reasonably likely to represent,
either a Material breach of any representation, warranty, covenant or agreement
of the other Party or which has had or is reasonably likely to have a Material
Adverse Effect on the other Party.

        8.6     Press Releases.  Prior to the Effective Time, DII and PSS shall
consult with each other as to the form and substance of any press release or
other public disclosure materially related to this Agreement or any other
transaction contemplated hereby; provided, that nothing in this Section 8.6
shall be deemed to prohibit any Party from making any disclosure which its
counsel deems necessary or advisable in order to satisfy such Party's
disclosure obligations imposed by Law.

        8.7     No Shopping.  Until the termination of this Agreement pursuant
to Article XI, except with respect to this Agreement and the transactions
contemplated hereby, neither DII nor any of its Subsidiaries or Affiliates, nor
any Representatives thereof shall directly or indirectly solicit or respond to
any Acquisition Proposal by any Person.  None of DII or any Affiliate or
Representative thereof shall furnish any non-public information, negotiate with
respect to, or enter into any Contract with respect to, any Acquisition
Proposal. DII shall promptly notify PSS orally and in writing in the event that
it receives any inquiry or proposal relating to any such transaction.  DII
shall (i) immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any Persons conducted heretofore with respect
to any of the foregoing, and (ii) direct and use its reasonable best efforts to
cause all of its Representatives not to engage in any of the foregoing.

        8.8     Accounting and Tax Treatment.  Each of the Parties undertakes
and agrees to use its best efforts to cause the Merger, and to take no action
which would cause the Merger not, to qualify for pooling-of-interests
accounting treatment and treatment as a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code for federal income tax purposes.

        8.9     Investment Agreement.  DII shall use its reasonable best
efforts to cause each shareholder of DII to deliver to PSS not later than 10
days prior to the Effective Time, a written agreement, substantially in the
form of Exhibit 8.9, providing that such Person will not sell, pledge,
transfer, or
<PAGE>   27

otherwise dispose of the shares of DII Common Stock held by such Person except
as contemplated by such agreement or by this Agreement and will not sell,
pledge, transfer, or otherwise dispose of the shares of PSS Common Stock to be
received by such Person upon consummation of the Merger except in compliance
with applicable provisions of the 1933 Act and the rules and regulations
thereunder and until such time as financial results covering at least 30 days of
combined operations of PSS and DII have been published within the meaning of
Section 201.01 of the SEC's Codification of Financial Reporting Policies.  If
the Merger will qualify for pooling-of-interests accounting treatment, shares of
PSS Common Stock issued to such affiliates of DII in exchange for shares of DII
Common Stock shall not be transferable until such time as financial results
covering at least 30 days of combined operations of PSS and DII have been
published within the meaning of Section 201.01 of the SEC's Codification of
Financial Reporting Policies, regardless of whether each such person has
provided the written agreement referred to in this Section 8.9 (and PSS shall be
entitled to place restrictive legends upon certificates for shares of PSS Common
Stock issued to affiliates of DII pursuant to this Agreement to enforce the
provisions of this Section 8.9).


        8.10   Conditional Releases.  Simultaneously with the execution and
delivery of this Agreement, each officer and director of DII has executed and
delivered a Conditional Release, in the form of Exhibit 8.10 to this Agreement,
to be effective only if the Effective Time occurs.

        8.11    Registration Rights.  (a)  After (i) February 15, 1997 if the
Closing Date occurs prior to December 1, 1996 or (ii) May 15, 1997 if the
Closing Date occurs on or after December 1, 1996, PSS shall, upon the written
demand of shareholders of DII holding an aggregate of at least fifty (50)
percent of DII Common Stock prior to Closing ("Registration Affiliate"), use its
best efforts to effect the registration (the "Demand Registration") under the
1933 Act of such number of Shares held by such Registration Affiliate as shall
be indicated in a written demand sent to PSS; provided, that (a) PSS shall only
be obligated to effect one Demand Registration, (b) PSS shall not be required to
register in the Demand Registration an amount of PSS Common Stock which is less
than $1,000,000 in market value.  Upon receipt of the Registration Affiliate's
written demand, PSS shall expeditiously effect the registration under the 1933
Act of the shares of PSS Common Stock as to which registration was demanded and
use its best efforts to have such registration declared effective as soon as
practicable after the filing thereof; provided, that PSS shall not be required
to file any registration statement during any period of time (not to exceed an
aggregate of ninety days) when (a) PSS is contemplating a public offering of its
securities and, in the judgment of the managing underwriter thereof (or PSS, if
such offering is not underwritten) such filing would have a material adverse
effect on the contemplated offering; (b) PSS is in possession of material
information that it deems advisable not to disclose in a registration statement;
or (c) PSS is engaged in a program for the repurchase of shares of PSS Common
Stock.

        (b) If PSS proposes to register any of its securities under the 1933 Act
for sale for cash (otherwise than in connection with registration of securities
issuable pursuant to an employee stock option, stock purchase or similar plan or
pursuant to a merger, exchange offer or a transaction of the type specified in
Rule 145(a) under the Securities Act), PSS shall give the Registration
Affiliates notice of such proposed registration at least 20 days prior to the
filing of a registration statement.  At the written request of a Registration
Affiliate delivered to PSS within 15 days after the receipt of the notice from
PSS, which request shall state the number of shares of PSS Common Stock that the
Registration Affiliate wishes to sell or distribute publicly under the
registration statement proposed to be filed by PSS, PSS shall use its best
efforts to effect the registration ("Piggyback Registration") under the 1933 Act
of such shares, and to cause such registration to remain effective for a
reasonable period of time not to exceed 45 days or such longer period of time
acceptable to PSS; provided that PSS may, without the consent of the
Registration Affiliate, withdraw such registration statement prior to its
becoming effective if PSS has abandoned its proposal to register its securities.
If the managing underwriters thereof advise PSS in writing that in their opinion
the

<PAGE>   28


number of securities requested to be included in the registration exceeds
the number which can be sold in the offering, PSS shall include in the
registration the shares the Registration Affiliate proposes to sell and the
securities PSS proposes to sell in proportion to the number of shares each
proposes to sell.

        (c) Nothwithstanding anything to the contrary herein, the Registration
shall have no rights to a Demand Registration or Piggyback Registration after
two (2) years after the Effective Time

        (d)  In the event of any registration of any shares of PSS Common Stock
held by Registration Affiliates under the 1933 Act, PSS shall, and hereby does,
indemnify and hold harmless in the case of any Demand or Piggyback Registration,
the Registration Affiliates, their directors and officers and each other Person,
if any, who controls such seller within the meaning of Section 15 of the 1933
Act, against any losses, claims, damages or liabilities, joint or several, to
which the Registration Affiliates or any such director or officer or controlling
person may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such shares were registered under the
1933 Act, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, or any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein in light of the circumstances in
which they were made not misleading, and PSS shall reimburse the Registration
Affiliates, and each such director, officer and controlling person, for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, action or
proceeding; provided that PSS shall not be liable in any such case to the extent
that any such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from such
registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to PSS through an instrument duly executed by
or on behalf of such Registration Affiliate, specifically stating that it is for
use in the preparation thereof. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of PSS, or any such
director, officer or controlling person and shall survive the transfer of such
shares by the Registration Affiliate.


        (e)  PSS may require, as a condition to including any shares of PSS
Common Stock to be offered by a Registration Affiliate in any registration
statement filed pursuant to this Section 8.11, that PSS shall have received an
undertaking reasonably satisfactory to it from such Registration Affiliate, to
indemnify and hold harmless in the case of any Demand or Piggyback Registration,
PSS, its directors and officers and each other Person, if any, who controls PSS
within the meaning of Section 15 of the 1933 Act, against any losses, claims,
damages or liabilities, joint or several, to which PSS or any such director or
officer or controlling person may become subject under the Securities Act or
state securities laws, insofar as such losses, claims, damages or liabilities
(or actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
in or omission or alleged omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus contain therein,
or any amendment or supplement thereto, if such statement or alleged statement
or omission or alleged omission was made in reliance upon and in conformity with
written information about such Registration Affiliate as a shareholder of PSS
furnished to PSS through an instrument duly executed by such Registration
Affiliate specifically stating that it is for use in the preparation of such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement.  Such indemnity shall remain in full force
and effect, regardless of any

<PAGE>   29

investigation made by or on behalf of PSS or any such director, officer or
controlling person and shall survive the transfer by any Registration Affiliate
of such shares.

        (f) Promptly after receipt by an undemnified party of notice of the
commencement of any action or proceeding involving a claim referred to in
Section 8.11(d) or (e), such indemnified party shall, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; provided that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under Section 8.11(d) or (e), except to
the extent that the indemnifying party is actually prejudiced by such failure to
give notice.  In case any such action is brought against an indemnified party,
unless in such indemnified party's reasonable judgment a conflict of interest
between such indemnified and indemnifying parties may exist or the indemnified
party may have defenses not available to the indemnifying party in respect of
such claim, the indemnifying party shall be entitled to participate in and to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation.  No party shall be
liable for any settlement of any action or proceeding effected without its
consent.  No indemnifying party shall, without the consent of the indemnified
party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
of such claim or litigation.

        (g)  The indemnification required by Section 8.11(d) and (e) shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills not contested in good faith are
received or expense, loss, damage or liability is actually incurred.

        (h)  In the event that any shares of PSS Common Stock held by a
Registration Affiliate are to be registered pursuant to this Section 8.11, PSS
covenants and agrees that it shall use its best efforts to effect the
registration and cooperate in the sale of such shares to be registered and
shall, subject to PSS's rights to delay or withdraw certain registrations, as
expeditiously as reasonably possible:

             (i)  prepare and file with the SEC a registration statement on the
        shortest form registration statement for which PSS then qualifies 
        (including registration statements on Form S-3 or Form S-2) with 
        respect to the shares (as well as any necessary amendments or 
        supplements thereto) and use its best efforts to cause the registration
        statement to become effective and, upon the request of the Registration
        Affiliates, keep such registration statement effective for a reasonable
        period of time as requested by the Registration Affiliates not to
        exceed 60 days;

             (ii)  notify the Registration Affiliates, promptly after PSS shall
        receive notice thereof, of the time when the registration statement
        becomes effective;

             (iii) advise the Registration Affiliates after PSS shall receive 
        notice or otherwise obtain knowledge of the issuance of any order by the
        SEC suspending the effectiveness of the registration statement or 
        amendment thereto or of the initiation or threatening of any proceeding
        for that purpose and promptly use its best efforts to prevent the 
        issuance of any stop order or to obtain its withdrawal promptly if a 
        stop order should be issued;

             (iv) furnish to the Registration Affiliates such number of copies 
        of the registration statement, each amendment and supplement thereto, 
        the prospectus included in the registration
<PAGE>   30

        statement (including each preliminary prospectus) and such other 
        documents as the Registration Affiliates may reasonably request in 
        order to facilitate the disposition of the shares of PSS Common Stock 
        owned by the Registration Affiliates;

             (v) enter into such customary agreements (including an underwriting
        agreement in customary form, including appropriate mutual 
        indemnification provisions) and take all such other action, if any, as
        the Registration Affiliates or the underwriters shall reasonably
        request in order to expedite or facilitate the disposition of such
        shares;

             (vi) use its best efforts to register or qualify the shares of PSS

        Common Stock under the securities or blue sky laws of such jurisdiction
        as the Registration Affiliate may reasonably request; and

             (vii) notify the Registration Affiliates, at any time when a 

        prospectus relating thereto is required to be delivered under the 1933 
        Act, of the occurrence of any event as a result of which the 
        Registration Statement would contain an untrue statement of material
        fact or omit to state any material fact required to be stated therein
        or necessary to make the statements therein not misleading, at which
        time any sales pursuant to such Registration Statement shall cease,
        and, as soon as practicable after PSS reasonably deems, if appropriate,
        to disclose such information in a registration statement, prepare a
        supplement or amendment to the Registration Statement so that such
        Registration Statement shall not, to PSS' knowledge, contain an untrue
        statement of material fact or omit to state any material fact required
        to be stated therein or necessary to make the statements therein not
        misleading.

        (i)  PSS shall pay one-half and the Registration Affiliates shall pay
one-half of all expenses (which shall be shared with other persons whose shares
are being registered in the Registration Statement) in connection with any
Demand Registration and PSS shall pay all expenses in connection with any
Piggyback Registration, which expenses include without limitation, all
registration, filing and NASD fees, all fees and expenses of complying with
securities or blue sky laws, and the reasonable fees and disbursements of
counsel for PSS and of its independent accountants.  Notwithstanding the
foregoing, in any registration, each party shall pay for its own underwriting
discounts and commissions and transfer taxes.

       (j)  The Registration Affiliates may not assign their rights under this
Section 8.11 to anyone without the prior written consent of PSS, and any
attempted transfer in violation of this Section 8.11(j) shall be null and void.

        8.12  Conditions to Closing.  DII and PSS agree to use their
commercially reasonable efforts to satisfy the closing conditions set forth in
Article 9 of this Agreement by October 31, 1996, and if not by such time, as
soon thereafter as possible.


                                   ARTICLE 9
               CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

        9.1     Conditions to Obligations of Each Party.  The respective
obligations of each Party to perform this Agreement and consummate the Merger
and the other transactions contemplated hereby are subject to the satisfaction
of the following conditions, unless waived by both Parties pursuant to Section
11.6 of this Agreement:

<PAGE>   31

                (a)  Regulatory Approvals.  All Consents of, filings and
registrations with, and notifications to, all Regulatory Authorities required
for consummation of the Merger shall have been obtained or made and shall be in
full force and effect and all waiting periods required by Law shall have
expired.  No Consent so obtained which is necessary to consummate the
transactions contemplated hereby shall be conditioned or restricted in a manner
which in the reasonable judgment of the Board of Directors of PSS would so
materially adversely impact the economic or business benefits of the
transactions contemplated by this Agreement so as to render inadvisable the
consummation of the Merger.

                (b)  Consents and Approvals.  Except as set forth on Schedule
9.1, each Party shall have obtained any and all Consents required for
consummation of the Merger or for the preventing of any Default under any
Contract or Permit of such Party which, if not obtained or made, is reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect on
such Party.  Except as set forth on Schedule 9.1, no Consent so obtained which
is necessary to consummate the transactions contemplated hereby shall be
conditioned or restricted in a manner which in the reasonable judgment of the
Board of Directors of PSS would so materially adversely impact the economic or
business benefits of the transactions contemplated by this Agreement so as to
render inadvisable the consummation of the Merger.

                (c)  Legal Proceedings.  No court or governmental or regulatory
authority of competent jurisdiction shall have enacted, issued, promulgated,
enforced or entered any Law or Order (whether temporary, preliminary or
permanent) or taken any other action which prohibits, restricts or makes illegal
consummation of the transactions contemplated by this Agreement.

        9.2     Conditions to Obligations of PSS.  The obligations of PSS to
perform this Agreement and consummate the Merger and the other transactions
contemplated hereby are subject to the satisfaction of the following conditions,
unless waived by PSS pursuant to Section 11.6(a) of this Agreement:

                (a)  Representations and Warranties.  The representations and
warranties of DII set forth or referred to in this Agreement shall be true and
correct in all Material respects (except that those representations and
warranties which are qualified as to materiality shall be true and correct in
all respects) as of the date of this Agreement and as of the Effective Time with

PHYSICIAN SALES & SERVICE COMPLETES MERGER WITH RADIOLOGY AND IMAGING
DISTRIBUTOR

November 27, 1996, 8:15 AM EST

JACKSONVILLE, Fla.--(BUSINESS WIRE)--Nov. 27, 1996--Physician Sales & Service,
Inc. (Nasdaq:PSSI) today announced that it completed the merger with
Diagnostic Imaging, Inc. ("DII") of Jacksonville, Florida.  DII distributes
radiology and imaging equipment, chemicals and supplies, and provides technical
service to the acute and alternate site markets through 13 locations in 5
southeastern states.  DII reported $58 million in revenues for the twelve month
period ended June 30, 1996.

The agreement is a stock-for-stock transaction, to be accounted for as a
pooling of interest, by issuing approximately 662,000 shares of PSS's common
stock.  As part of the transaction, PSS also assumes approximately $4.9 million
of outstanding DII debt.

Commenting on the merger, Patrick Kelly, Chairman and Chief Executive Officer,
stated, "This transaction represents an important opportunity for PSS to expand
our product offerings to the physician market, which accounts for approximately
$1.2 billion in sales of radiology and imaging equipment, services and
supplies.  Currently, the radiology and imaging equipment, chemicals and
supplies market totals approximately $4.1 billion.  We plan to aggressively
pursue consolidation opportunities in this niche market, which is comprised of
over 450 distributors."

Mr. Kelly added, "We are also pleased to announce the appointment of Frederick
E. "Gene" Dell to President of DII.  Gene has served as Regional Vice President
of PSS since December 1993 and in various sales and management positions with
PSS since April 1984.  We believe Gene will provide DII with focus and
commitment to complete customer satisfaction, attributes responsible for past
and future successes of PSS."

PSS is a leading distributor of medical supplies, equipment and pharmaceuticals
to primary care and other office-based physicians in the United States and
distributes in Europe through WorldMed, Inc.
