                              SEPARATION AGREEMENT

         This SEPARATION AGREEMENT (this "Agreement"), dated as of August __,
1996, is made by and between INTERPOINT CORPORATION, a Washington corporation
("Interpoint") and ADVANCED DIGITAL INFORMATION CORPORATION, a wholly owned
subsidiary of Interpoint and a Washington corporation ("ADIC").

                                    RECITALS

         A.       Interpoint has entered into an Agreement and Plan of Merger
among Crane Co., a Delaware corporation ("Crane"), Crane Acquisition Corp., a
Washington corporation and a wholly owned subsidiary of Crane ("Acquisition
Sub"), and Interpoint dated as of July 1, 1996 (the "Merger Agreement"),
providing for the merger of Interpoint with Acquisition Sub. It is a condition
precedent to the closing of the Merger that Interpoint spinoff ADIC to
Interpoint shareholders. B. The Board of Directors of Interpoint has determined
that it is appropriate and desirable to separate ADIC from Interpoint by
distributing as a dividend to the holders of shares of common stock, no par
value per share, of Interpoint (the "Interpoint Common Stock") immediately prior
to the effective time of the Merger all outstanding shares of common stock, no
par value per share, of ADIC (the "ADIC Common Stock"). C. Interpoint and ADIC
have determined that it is necessary and desirable to set forth the principal
corporate transactions required to effect such separation and dividend
distribution and to set forth other agreements that will govern certain other
matters following such distribution. This Agreement together with the Tax
Allocation Agreement (as defined below) constitute the "Spinoff Agreements" as
such term is used in the Merger Agreement. NOW, THEREFORE, in consideration of
the mutual agreements, provisions and covenants contained in this Agreement, the
parties hereby agree as follows:

                                   ARTICLE III

                                EMPLOYEE BENEFITS

3.01     401(K) PLAN

         (a)      As soon as practicable after the date hereof and effective as
of the Effective Time, ADIC shall take, or cause to be taken, all action
necessary and appropriate to establish and administer the New ADIC 401(k) Plan,
which will be a Qualified Plan, and to provide benefits thereunder for all ADIC
Employees, including former ADIC Employees, who, as of the Effective Time, were
participants in or otherwise entitled to benefits under the Interpoint 401(k)
Plan. ADIC agrees that each such ADIC Employee will be, to the extent
applicable, entitled, for all purposes under the new ADIC 40l(k) Plan, to be
credited with the term of service credited to such ADIC Employee as of the
Effective Time under the terms of the Interpoint 401(k) Plan.

         (b)      Interpoint agrees to prepare and provide to ADIC, as soon as
practicable after the Effective Time, a list of the ADIC Employees, including
former ADIC Employees, who were participants in or otherwise entitled to
benefits under the Interpoint 401(k) Plan as of the Effective Time, together
with a listing of each such ADIC Employee's term of service for eligibility and
vesting purposes under such Plan and a listing of each such ADIC Employee's
"Estimated Account Balance" thereunder. An ADIC Employee's "Estimated Account
Balance" is his or her account balances under the Interpoint 401(k) Plan as of
the last day of the quarter immediately preceding the quarter in which the
Distribution occurs plus employee salary deferral contributions, loan payments,
employer matching contributions and any other contributions made to the
Interpoint 401(k) Plan by or on behalf of such ADIC Employee during the quarter
in which the Distribution occurs, less any withdrawals or new loans made from
such accounts during such quarter, plus estimated earnings allocable to such
accounts for such quarter. Interpoint and ADIC agree to provide one another with
such additional information in the possession of one company and not already in
the possession of the other as may be reasonably requested by either of them and
necessary in order for ADIC to establish and administer effectively the New ADIC
401(k) Plan. For purposes of this Section 3.01, "quarter" means any of the three
month periods ending on the last day of August, November, February or May.

         (c)      Interpoint agrees to direct the trustee of the trust funding
the Interpoint 401(k) Plan to transfer, on the first business day of the quarter
commencing after the quarter in which

                                      -10-
<PAGE>   11
the Distribution occurs, to the trustee or other funding agent of the New ADIC
401(k) Plan, an amount equal to the total Estimated Account Balances of all ADIC
Employees, including former ADIC Employees. As soon as administratively
practicable after the reconciliation of the Interpoint 401(k) Plan trust to
participant accounts for the quarter in which the Distribution occurs has been
completed by the recordkeeper of the Interpoint 401(k) Plan, Interpoint shall
direct the trustee of that trust to transfer any amounts remaining in the
Interpoint 401(k) Plan accounts of ADIC Employees, including former ADIC
Employees, to the trustee or other funding agent of the New ADIC 401(k) Plan and
shall provide ADIC with a listing of the account balances of each ADIC Employee,
including each former ADIC Employee, under the Interpoint 401(k) Plan as of the
last day of the quarter in which the Distribution occurs. ADIC agrees that,
following such transfer, each ADIC Employee on whose behalf assets were
transferred will be credited with an account balance under the New ADIC 401(k)
Plan equal to the amount transferred from the Interpoint 401(k) Plan to the New
ADIC 401(k) Plan on behalf of such ADIC Employee (adjusted, as necessary, for
any investment gains or losses incurred (and for any other transaction
occurring) with respect to such account under the New ADIC 401(k) Plan from the
date of the initial transfer of assets through the date of the final transfer of
assets to the New ADIC 401(k) Plan from the Interpoint 401(k) Plan).

         (d)      Interpoint and ADIC shall, in connection with the transfers
described in this Section 3.01, cooperate in making any and all appropriate
filings required under the Code or ERISA, and the regulations thereunder, and
any applicable securities laws, and take all such action as may be necessary and
appropriate to cause such transfers to take place at the times specified in this
Section 3.01.

         (e)      Except for liabilities and obligations arising under ERISA or
the Code (including, but not limited to, Sections 409, 502(i) and 502(l) of
ERISA and Sections 4972 and 4975 of the Code) with respect to events, actions or
inactions occurring prior to the final transfer referred to in Section 3.01(c)
(other than liabilities and obligations relating to events, actions or inactions
occurring with respect to the Advanced Digital Information Corporation 401(k)
Retirement Plan prior to the June 8, 1996 transfer of such plan's assets to the
Interpoint 401(k) Plan) and liabilities and obligations arising out of, related
to or in any way connected with matters disclosed in the Disclosure Letter,
after the final transfer referred to in Section 3.01(c) occurs, Interpoint and
the Interpoint Subsidiaries shall cease to have any liability or obligation
whatsoever with respect to ADIC Employees under the Interpoint 401(k) Plan, and
ADIC shall assume or retain, as the case may be, and shall be solely responsible
for, all liabilities and obligations whatsoever with respect to ADIC Employees
under the Interpoint 401(k) Plan and shall be solely responsible for all
liabilities or obligations whatsoever under the New ADIC 401(k) Plan; provided,
however, that if as a result of the IRS audit disclosed in the Disclosure
Letter, the IRS requires that any action(s) be taken with respect to the ADIC
Employees' account balances transferred to the New ADIC 401(k) Plan from the
Interpoint 401(k) Plan to retain the Interpoint 401(k) Plan's and/or the New
ADIC 401(k) Plan's tax-qualified status, then Interpoint will take (or will
direct the trustee of the Interpoint 401(k) Plan to take) such action(s) with
respect to the Interpoint 401(k) Plan and

                                      -11-
<PAGE>   12
ADIC will direct the trustee of the New ADIC 401(k) Plan to make such
distributions from ADIC Employees' account balances under the New ADIC 401(k)
Plan as the IRS may require to retain the Interpoint 401(k) Plan's and the New
ADIC 401(k) Plan's tax-qualified status with respect to the account balances
transferred to the New ADIC 401(k) Plan from the Interpoint 401(k) Plan. ADIC
shall either be responsible for or make all required contributions, no later
than the later of the Effective Time and the date such contributions are legally
required to be made, in respect of ADIC Employees with respect to the Interpoint
401(k) Plan to the extent not previously made.

3.02    WELFARE PLANS

        (a)      Interpoint and the Interpoint Subsidiaries shall assume or
retain all Liabilities and obligations whatsoever for benefits of Interpoint
Employees and their spouses and dependents under any Welfare Plan. Except as
provided in Section 3.02(b), as of the Effective Time or as soon thereafter as
may be agreed upon by Interpoint, ADIC and the applicable insurance carriers,
but no later than December 31, 1996, ADIC shall cease to co-sponsor any Welfare
Plans with Interpoint or any Interpoint Subsidiary; provided, however, that ADIC
Employees and their spouses and dependents participating in Interpoint Welfare
Plans co-sponsored by ADIC or an ADIC Subsidiary shall remain entitled to
benefits under (and in accordance with the terms of) such Welfare Plans for
covered expenses incurred and benefits accrued prior to the time at which their
participation in such Welfare Plans ceases. With respect to the insured medical
and dental plan(s) co-sponsored by Interpoint and ADIC for eligible employees
and their spouses and dependents, ADIC agrees to pay a pro rata share (based on 
number of participants) of any claims runoff for benefits incurred prior to
the time ADIC Employees and their spouses and dependants cease to participate
in such plan(s) that requires additional payments to the insurance company
over and above the amount reserved on Interpoint's books for such purpose at
the Effective Time, and Interpoint agrees that it will refund to ADIC, at such
time as such reserve is no longer subject to runoff claims for benefits
incurred prior to the time ADIC Employees and their spouses and dependants
cease to participate in such plan(s), a pro rata share (based on number of
participants) of any portion of such reserve that is not utilized to pay such
benefits. ADIC shall also be responsible for providing COBRA coverage under
Code Section 4980B for former ADIC Employees and their covered dependents who
are entitled to COBRA coverage on and after the date ADIC ceases to co-sponsor
the Interpoint medical and dental plan(s). ADIC shall also be liable for any
retiree medical coverage liabilities to retired ADIC Employees and their
dependents, and for any severance benefits payable to any ADIC Employee under
an severance pay plan or policy.

        (b)      Interpoint shall permit ADIC and any ADIC Subsidiaries to
co-sponsor any Interpoint Welfare Plan(s) (except for any severance pay plan)
for such period following the Effective Time as may be agreed upon by
Interpoint, ADIC and the applicable insurance carriers, but not later than
December 31, 1996; provided that ADIC and any ADIC Subsidiaries shall pay the
costs associated with such co-sponsorship for ADIC Employees and their spouses
and dependants on the same basis as Interpoint pays the costs associated with
such co-sponsorship for Interpoint Employees and their spouses and dependants.

3.03     STOCK OPTION PLANS

         (a)      Interpoint shall take, or cause to be taken, all actions
necessary and appropriate to effect the Option Cash Out Program, pursuant to
which (i) each Interpoint Stock Option held by an Interpoint Holder will be
cancelled and in exchange therefor the Interpoint Holder will receive a cash
payment equal to the difference between the exercise price of such option and
the average of the high and low sale prices of the Interpoint Common Stock on
each of the 10 trading days prior to (but not including the date of) the
Effective Time (the "Interpoint Average Stock Price") and (ii) each Interpoint
Stock Option held by an ADIC Holder will be adjusted by Interpoint so as to
represent two separate options, one to purchase Interpoint Common Stock and the
other to purchase ADIC Common Stock (an "Adjusted Interpoint Option" and an
"Adjusted ADIC Option," respectively). Each Adjusted Interpoint Option will be
cancelled and in exchange therefor the ADIC Holder will receive a cash payment
equal to the difference between (1) the exercise price of such Adjusted
Interpoint Option (determined as described below) and (2) the Aggregate Share
Distribution Amount (as defined in the Merger Agreement) divided by the number
of shares of Interpoint Common Stock outstanding immediately prior to the
Merger. Each Adjusted ADIC Option will be exercisable for the same number of
shares as was originally covered by the related Interpoint Stock Option prior to
the Effective Time, and will have substantially the same other terms as such
Interpoint Stock Option except for the exercise price and except that Adjusted
ADIC Options will be administered pursuant to the ADIC 1996 Transition Plan. The
exercise price of each Adjusted Interpoint Option will be determined by
multiplying the per share exercise price of the original option by a fraction
the numerator of which is the Aggregate Share Distribution Amount and the
denominator of which is the Interpoint Average Stock Price . The exercise price
per share of the Adjusted ADIC Option will be the difference between the
exercise price of the original Interpoint Stock Option and the exercise price of
the Adjusted Interpoint Option.

         (b)      For purposes of this Section 3.03, all members of Interpoint's
Board of Directors who are not Interpoint Employees will be deemed to be ADIC
Holders.

3.04     INTERPOINT MIP AND PROFIT SHARING

         Interpoint and ADIC will, to the extent practicable, each continue
accruing for payments under, and shall make payments in accordance with, the
Interpoint MIP and Interpoint Profit Sharing Plan for the fiscal year ended
October 31, 1996. Each of ADIC and Interpoint shall be responsible for the
determination and payment of awards to their respective employees for the fiscal
year ended October 31, 1996. The payments to be made to Peter van Oppen under
the Interpoint MIP and Interpoint Profit Sharing Plan will be made by
Interpoint.

3.05     OTHER BALANCE SHEET ADJUSTMENTS

         To the extent not otherwise provided in this Agreement, Interpoint and
ADIC shall take such action as is necessary to effect an adjustment to the books
of Interpoint and ADIC so that, as of the Effective Time, the prepaid expense
balances and accrued employee liabilities

                                      -13-
<PAGE>   14
with respect to any employee liability or obligation assumed or retained as of
the Effective Time (except to the extent a later time is agreed upon as provided
in this Agreement) by Interpoint and the Interpoint Subsidiaries, on the one
hand, and ADIC and the ADIC Subsidiaries, on the other hand, are appropriately
reflected on the respective consolidated balance sheets as of the Effective
Time, respectively, of Interpoint and ADIC.

3.06     PRESERVATION OF RIGHTS TO AMEND OR TERMINATE PLANS

         No provision of this Agreement, including, without limitation, the
agreement of Interpoint or ADIC that it, or any Interpoint Subsidiary or ADIC
Subsidiary, will make a contribution or payment to or under any Plan herein
referred to for any period, shall be construed as a limitation on the right of
Interpoint or ADIC or any Interpoint Subsidiary or ADIC Subsidiary to amend or
terminate such Plan which Interpoint or ADIC or any Interpoint Subsidiary or
ADIC Subsidiary would otherwise have under the terms of such Plan or otherwise,
and no provision of this Agreement shall be construed to create a right in any
employee or former employee or beneficiary of such employee or former employee
under a Plan which such employee or former employee or beneficiary would not
otherwise have under the terms of the Plan itself.

                                   ARTICLE IV

                                    INSURANCE

4.01     CONTINUATION OF ADIC RIGHTS UNDER INTERPOINT POLICIES

         Interpoint and ADIC agree that, following the Effective Time, ADIC
shall retain all rights of an insured party (to the extent ADIC is an insured
party) under each of the Interpoint Policies with respect to any injury, loss,
liability, damage or expense incurred or claimed to have been incurred prior to
the Effective Time by any party in or in connection with the conduct of the ADIC
Business or against ADIC or any ADIC Subsidiary, to the extent that such injury,
loss, liability, damage or expense may arise out of insured or insurable
occurrences or events under one or more of the Interpoint Policies. If,
subsequent to the Effective Time, any person, corporation, firm or entity shall
assert such a claim against ADIC or any ADIC Subsidiary, Interpoint shall at the
time such claim is asserted be deemed to assign, without need of further
documentation, to ADIC any and all rights of an insured party under the
applicable Interpoint Policy with respect to such asserted claim, specifically
including rights of indemnity, if any, and the right, if any, to be defended by
or at the expense of the insurer; provided, however, that nothing in this
paragraph shall be deemed to constitute (or to reflect) the assignment of the
Interpoint Policies, or any of them, to ADIC.

4.02     ADMINISTRATION AND ALLOCATIONS

         (a)      Administration. From and after the Effective Time, Interpoint
shall be responsible for accounting for premiums,indemnity payments, deductibles
and retentions, as appropriate under the terms and conditions of each of the
Interpoint Policies; distributing

                                      -14-
<PAGE>   15
Insurance Proceeds as contemplated by this Agreement; reporting to insurers its
own Insured Claims and those Insured Claims which ADIC has reported to it; and
processing and managing Insured Claims made under the Interpoint Policies based
upon supporting information and documentation provided by the party submitting
such Insured Claim; provided that Interpoint's retention of the administrative
responsibilities for the Interpoint Policies listed in this paragraph (a) will
not relieve the party submitting any Insured Claim of the primary responsibility
for reporting such Insured Claim accurately, completely and in a timely manner.
Each of Interpoint and ADIC shall administer and pay any costs related to
defending its respective Insured Claims under the Interpoint Policies to the
extent such defense costs are not covered under such policies, and will be
responsible for obtaining or reviewing the appropriateness of releases upon
settlement of its respective Insured Claims under the Interpoint Policies. The
retention of the Interpoint Policies by Interpoint is in no way intended to
limit, inhibit or preclude any right to insurance coverage for any Insured Claim
of a named insured under the Interpoint Policies, including, but not limited to,
ADIC and any of its operations, and any ADIC Subsidiary or Affiliate.

         (b)      Insurance Premiums.

                  (i)      Prepaid Premiums. Upon the written request of ADIC,
Interpoint shall promptly direct the insurance carrier for each Interpoint
Policy on which premiums will be prepaid as of the Effective Time to credit the
amount of each such prepayment made by ADIC against the premiums to be paid by
ADIC on the comparable policy to be effective for ADIC following the
Distribution. ADIC shall not receive such credit for any such prepaid premium
that was not paid by ADIC prior to the Effective Time.

                  (ii)     Premium Adjustment for Package Policy. In the event
that upon the cancellation or termination of the "package policy" there are
additional premiums payable, or entitlement to return of premiums previously
paid, with respect to such policy as a result of the actual sales of Interpoint
and ADIC, then such amounts shall be paid by, or refund paid to, Interpoint
and/or ADIC, as the case may be, to the extent that such additional payment or
refund arises due to sales of that party..

         (c)      Allocation of Policy Limits. Interpoint and ADIC agree that
where ADIC Liabilities are specifically covered under Interpoint Policies in
effect for periods prior to the Effective Time, then from and after the
Effective Time ADIC may claim for Insured Claims under each such Interpoint
Policy as and to the extent that such insurance is available up to the full
extent of the applicable fixed dollar coverage limits of the policy, subject to
the terms of this Section 4.02(c). Except with respect to Interpoint Policies
providing for directors and officers liability insurance coverage which are not
be subject to the remainder of this Section 4.02(c), in the event that the
aggregate of Insured Claims by Interpoint and ADIC have exhausted the fixed
dollar coverage limits under a particular Interpoint Policy, taking into account
defense costs to the extent such costs are applied against such limits of such
policy, then the party that has utilized more than its "allocable portion" (as
defined below) of the fixed dollar coverage limits under such Policy (the
"benefitted party") shall indemnify the party

                                      -15-
<PAGE>   16
which utilized less than its allocable portion of such fixed dollar coverage
limits (the "nonexceeding party") for any subsequent claim by the nonexceeding
party (including, without limitation, defense costs related to such claim)
arising out of an insured or insurable occurrence or event under such Interpoint
Policy which would have been an Insured Claim but for the fact that the limits
of such Interpoint Policy were exceeded, up to the difference between such
parties allocable portion of the fixed dollar coverage limits under such
Interpoint Policy and the amount of such fixed dollar coverage limits (excluding
defense costs to the extent such costs are not applied against the fixed dollar
coverage limits) actually utilized by the nonexceeding party (the "maximum
reimbursement amount"). The nonexceeding party shall submit to the benefitted
party the same information and documentation that it would have been required to
submit to the insurance carrier under the applicable Interpoint Policy within
the same time frames provided for in such Interpoint Policy, and the benefitted
party shall, within 30 days of receipt of documentation supporting such claim,
either pay such claim or give written notice denying the claim to the
nonexceeding party. ADIC's "allocable portion" is the percentage of consolidated
Interpoint sales attributable to the ADIC business for the 1996 fiscal year
prior to the Merger, and Interpoint's "allocable portion" is the percentage of
consolidated Interpoint sales attributable to the Interpoint Business for the
same period.

         In the event the benefitted party denies any claim, then the parties
shall select an independent insurance coverage expert within 30 days of the
notice of denial. If the parties are unable to agree on an independent insurance
coverage expert, then each party shall select one independent insurance coverage
expert within 45 days of the notice of denial, and a third independent insurance
coverage expert shall be selected by mutual agreement of the first two
independent insurance coverage experts within 60 days of the notice of denial.
If the parties agree on the selection of an independent insurance coverage
expert, such expert so selected, or if the parties do not so agree, the third
independent insurance coverage expert so selected, shall interpret the terms,
provisions and conditions of the applicable Interpoint Policy and shall
determine, within 45 days of being selected, whether the claim would have been
an Insured Claim under such Interpoint Policy and the amount of reimbursement
that the nonexceeding party will receive in settlement of such claim; provided,
however, that the aggregate amount of claims paid by a benefitted party under
this paragraph (c) shall not exceed the maximum reimbursement amount.

         The decision of the independent insurance coverage expert will be final
and binding on the parties, and no appeal may be taken from that decision. Fees
and costs for attorneys, experts and all independent insurance coverage experts
will be borne equally by the parties. This agreement of the parties to submit
disputes between them to the procedures set forth in this paragraph (c) will not
be deemed a waiver of legal defenses, including, but not limited to, statutes of
limitations, that either party may have.

         Except as set forth in this paragraph (c) or in paragraph (d) of this
Section 4.02, Interpoint and ADIC will not be liable to one another for claims
by the other not reimbursed by insurers for any other reason whatsoever not
within the control of Interpoint or ADIC, as

                                      -16-
<PAGE>   17
the case may be, including, but not limited to, coinsurance provisions, 
deductibles, quota share deductibles, self-insured retentions, bankruptcy or 
insolvency of an insurance carrier, Interpoint Policy limitations or 
restrictions, any coverage disputes, any failure to timely claim by ADIC or 
Interpoint or any defect in such claim or its processing.

         (d)      Allocation of Insurance Deductibles. Insured Claims by both
Interpoint and ADIC shall be subject to, and shall apply toward the satisfaction
of, the full amount of applicable deductibles or self-insured retentions under
the Interpoint Policies; provided that, if the aggregate deductibles or
self-insured retentions under any Interpoint Policy (other than a Interpoint
Policy providing for directors and officers liability coverage) are exceeded and
one company benefits from the deductibles or retentions paid by the other, then
the benefitted company shall reimburse the other company to the extent of such
benefit up to its allocable portion of such aggregate deductible or retention
within 30 days of receipt of such benefit.

         (e)      Allocation of Insurance Proceeds. Interpoint shall direct the
insurance carriers to pay Insurance Proceeds with respect to claims, costs and
expenses under the Interpoint Policies directly to ADIC with respect to ADIC
Insured Claims and directly to Interpoint with respect to Interpoint's Insured
Claims. The parties agree to use their best efforts to cooperate with respect to
insurance matters.

4.03     AGREEMENT FOR SHARED DEFENSE

         In the event that Insured Claims of both ADIC and Interpoint exist
relating to the same occurrence, ADIC and Interpoint agree to jointly defend
such Insured Claim; provided, that, if, in the reasonable judgment of one party,
a conflict of interest between Interpoint and ADIC exists in respect of such
Insured Claim or if the other party assumes responsibility for such Insured
Claim with any reservations or exceptions, the party which concludes that a
conflict exists or that has not assumed responsibility for such Insured Claim
will have the right to employ separate counsel reasonably satisfactory to the
other party. In that event, the fees and expenses of such separate counsel will
be paid by the party retaining such counsel unless the other party shall have
indemnified such party against such fees and expenses pursuant to this Agreement
or otherwise. Nothing in this Section 4.03 shall be construed to limit or
otherwise alter in any way the indemnity obligations of the parties to this
Agreement, by operation of law or otherwise.

4.04     DIRECTORS AND OFFICERS LIABILITY INSURANCE POLICIES

         Interpoint shall comply with its obligations as set forth in Section
6.10 of the Merger Agreement with respect to Interpoint Policies providing for
directors and officers liability coverage.

                                 INDEMNIFICATION

5.01     INDEMNIFICATION BY INTERPOINT

         Except as otherwise set forth herein, Interpoint shall indemnify,
defend and hold harmless ADIC, each of its directors, officers, employees and
agents, each Affiliate of ADIC and each of the heirs, executors, successors and
assigns of any of the foregoing (the "ADIC Indemnitees") from and against any
and all Indemnifiable Losses of the ADIC Indemnitees arising out of, by reason
of or otherwise in connection with the Interpoint Liabilities.

5.02     INDEMNIFICATION BY ADIC

         Except as otherwise set forth herein, ADIC shall indemnify, defend and
hold harmless Interpoint, each of its directors, officers, employees and agents,
each Affiliate of Interpoint and each of the heirs, executors, successors and
assigns of any of the foregoing (the "Interpoint Indemnitees") from and against
any and all Indemnifiable Losses of the Interpoint Indemnitees arising out of,
by reason of or otherwise in connection with the ADIC Liabilities.

5.03     LIMITATIONS ON INDEMNIFICATION OBLIGATIONS

         The amount which any party (an "Indemnifying Party") is or may be
required to pay to any other party (an "Indemnitee") pursuant to Section 5.01 or
Section 5.02 shall be reduced (retroactively or prospectively) by any insurance
proceeds or other amounts actually recovered by or on behalf of such Indemnitee,
in reduction of the related Indemnifiable Loss. If an Indemnitee shall have
received the payment required by this Agreement from an Indemnifying Party in
respect of an Indemnifiable Loss and shall subsequently actually receive
insurance proceeds or other amounts in respect of such Indemnifiable Loss, then
such Indemnitee shall pay to such Indemnifying Party a sum equal to the amount
of such insurance proceeds or other amounts actually received, up to the
aggregate amount of any payments received from such Indemnifying Party pursuant
to this Agreement in respect of such Indemnifiable Loss.

5.04     PROCEDURE FOR INDEMNIFICATION

         (a)      If an Indemnitee shall receive notice or otherwise learn of
the assertion by a person (including, without limitation, any governmental
entity) who is not a party to this Agreement or the Merger Agreement of any
claim or of the commencement by any such person of any Action (a "Third Party
Claim") with respect to which an Indemnifying Party may be obligated to provide
indemnification pursuant to this Agreement, such Indemnitee shall give such
Indemnifying Party written notice thereof promptly after becoming aware of such
Third Party Claim; provided, however, that the failure of any Indemnitee to give
notice as provided in this Section 5.04 shall not relieve the applicable
Indemnifying Party of its obligations under this Article V, except to the extent
that such Indemnifying Party is

                                      -18-
<PAGE>   19
prejudiced by such failure to give notice. Such notice shall describe the Third
Party Claim in reasonable detail and shall indicate the amount (estimated if
necessary) of the Indemnifiable Loss that has been or may be sustained by such
Indemnitee.

         (b)      Subject to the proviso of the following sentence, an
Indemnifying Party shall defend or seek to settle or compromise, at such
Indemnifying Party's own expense and by such Indemnifying Party's own counsel,
any Third Party Claim. Within 30 days of the receipt of notice from an
Indemnitee in accordance with Section 5.04(a) (or sooner, if the nature of such
Third Party Claim so requires), the Indemnifying Party shall notify the
applicable Indemnitee whether the Indemnifying Party will assume responsibility
for defending such Third Party Claim, which notice must specify any reservations
or exceptions with respect to such assumption of responsibility; provided,
however, that an Indemnifying Party may elect not to assume responsibility for
defending a Third Party Claim only in the event of a good faith dispute that a
claim was appropriately tendered under Section 5.01 or 5.02, as the case may be,
in which case the Indemnitee may defend or seek to compromise or settle such
Third Party Claim. After notice from an Indemnifying Party to an Indemnitee of
its election to assume the defense of a Third Party Claim, such Indemnifying
Party will not be liable to such Indemnitee under this Article V for any legal
or other expenses (except expenses approved in advance by the Indemnifying
Party) subsequently incurred by such Indemnitee in connection with the defense
thereof; provided, that, if the defendants in any such claim include both the
Indemnifying Party and one or more Indemnitees and in such Indemnitees'
reasonable judgment a conflict of interest between such Indemnitees and such
Indemnifying Party exists in respect of such claim or if the Indemnifying Party
shall assume responsibility for such claim with any reservations or exceptions,
such Indemnitees will have the right to employ separate counsel reasonably
satisfactory to the Indemnifying Party to represent such Indemnitees, and in
that event the reasonable fees and expenses of such separate counsel (but not
more than one separate counsel) will be paid by such Indemnifying Party.

         (c)      If an Indemnifying Party elects to defend or to seek to
compromise any Third Party Claim, the appropriate Indemnitee shall (x) cooperate
in all reasonable respects with the Indemnifying Party in connection with such
defense, (y) not admit any liability with respect to, or settle, compromise or
discharge, such Third Party Claim without the Indemnifying Party's prior written
consent and (z) agree to any settlement, compromise or discharge of such Third
Party Claim which the Indemnifying Party may recommend and which by its terms
obligates the Indemnifying Party to pay the full amount of the liability in
connection with such Third Party Claim and which releases the Indemnifying Party
completely in connection with such Third Party Claim.

         (d)      In the event of payment by an Indemnifying Party to any
Indemnitee in connection with any Third Party Claim, such Indemnifying Party
shall be subrogated to and shall stand in the place of such Indemnitee as to any
events or circumstances with respect to which such Indemnitee may have any right
or claim relating to such Third Party Claim against any claimant or plaintiff
asserting such Third Party Claim. Such Indemnitee shall cooperate

                                    -19-
<PAGE>   20
with such Indemnifying Party in a reasonable manner, and at the cost and expense
of such Indemnifying Party, in prosecuting any subrogated right or claim.

        (e)     With respect to any Third Party Claim for which the 
Indemnifying Party assumes responsibility for defense, the Indemnifying Party
shall inform the Indemnitee, upon the reasonable written request of the
Indemnitee, of the status of efforts to resolve such Third Party Claim. With
respect to any Third Party Claim for which the Indemnifying Party does not
assume such responsibility, the Indemnitee shall inform the Indemnifying Party,
upon the reasonable written request of the Indemnifying Party, of the status of
efforts to resolve such Third Party Claim.

5.05     SURVIVAL OF INDEMNITIES

         The obligations of Interpoint and ADIC under this Article V shall
survive the sale or other transfer by it of any assets or businesses or the
assignment by it of any Liabilities, with respect to any Indemnifiable Loss of
the other related to such assets, businesses or Liabilities. All obligations of
Interpoint and ADIC under this Article V shall terminate five years after the
Distribution Date, except with respect to claims for which one party has
provided notice to the other prior to the end of such five-year period.

                              ACCESS TO INFORMATION

6.01     PROVISION OF CORPORATE RECORDS

         Interpoint shall use its best efforts to arrange, as soon as
practicable following the Distribution Date, for the transportation to ADIC of
all original agreements, documents, books, records and files relating to or
affecting ADIC, any ADIC Subsidiary or the ADIC Business (collectively
"Records"), to the extent such items are not already in the possession of ADIC
or a ADIC Subsidiary, subject to the following exceptions:

                  (i)      ADIC recognizes that certain Records may contain
incidental information relating to Interpoint and the Interpoint Subsidiaries or
may relate primarily to subsidiaries or divisions of Interpoint other than ADIC
and the ADIC Subsidiaries, and that Interpoint may retain such Records and
provide copies of the relevant portions thereof to ADIC; and

                  (ii)     Interpoint may retain any tax returns, reports, forms
or work papers, and ADIC will be provided with copies of such returns, reports,
forms or work papers only to the extent that they relate to or affect ADIC and
the ADIC Subsidiaries' returns or tax liability.

<PAGE>   21
6.02     ACCESS TO INFORMATION

         From and after the Distribution Date, each of Interpoint and ADIC shall
afford to the other and its authorized accountants, counsel and other designated
representatives reasonable access during normal business hours, subject to
appropriate restrictions for classified information, to the personnel,
properties, books and records of such party and its subsidiaries insofar as such
access is reasonably required by the other party.

6.03     CONFIDENTIALITY

         Each of Interpoint and the Interpoint Subsidiaries on the one hand, and
ADIC and the ADIC Subsidiaries on the other hand, shall hold, and shall cause
its respective consultants and advisors to hold, in strict confidence, all
information concerning the other in its possession (except to the extent that
such information has been (a) in the public domain through no fault of such
party or (b) later lawfully acquired from other sources by such party) to the
extent such information (i) relates to the period up to the Effective Time, (ii)
relates to this Agreement or (iii) is obtained from the other party pursuant to
this Agreement, and each party shall not release or disclose such information to
any other person, except its auditors, attorneys, financial advisors, bankers
and other consultants and advisors, unless compelled to disclose by judicial or
administrative process or, as advised by its counsel, by other requirements of
law.

                                   ARTICLE VII

                              ARTICLE 9. DIRECTORS

         The number of Directors of this corporation will be determined in the
manner provided by the Bylaws and may be increased or decreased from time to
time in the manner provided therein. The Board of Directors will be divided into
three classes, with said classes to be as equal in number as is possible. At the
first election of Directors to such classified Board of Directors, each Class 1
Director will be elected to serve until the next ensuing annual meeting of
shareholders, each Class 2 Director will be elected to serve until the second
ensuing annual meeting of shareholders and each Class 3 Director will be elected
to serve until the third ensuing annual meeting of shareholders. At each annual
meeting of shareholders following the meeting at which the Board of Directors is
initially classified, the number of Directors equal to the number of Directors
in the class whose term expires at the time of such meeting will be elected to
serve until the third ensuing annual meeting of shareholders. Notwithstanding
any of the foregoing provisions of this Article, Directors will serve until
their successors are elected and qualified or until their earlier death,
resignation or removal from office, or until there is a decrease in the number
of Directors.

         The Directors of this corporation may be removed only for cause. Any
such removal must be approved by the holders of not less than two-thirds of the
shares entitled to elect the Director or Directors whose removal is sought in
the manner provided by the Bylaws.

               ARTICLE 10. AMENDMENTS TO ARTICLES OF INCORPORATION

         This corporation reserves the right to amend or repeal by the
affirmative vote of the holders of a majority of the outstanding shares and, to
the extent, if any, provided by a resolution or resolutions of the Board of
Directors providing for the issuance of a series of Common Stock or Preferred
Stock, a majority of the outstanding shares entitled to vote

thereon, voting as a class, any of the provisions contained in these Articles of
Incorporation in any manner now or hereafter permitted by law; provided,
however, that amendment or repeal of Article 7, Article 9, Article 10, Article
12 or Article 13 shall require the affirmative vote of the holders of at least
two-thirds of the outstanding shares. The rights of the shareholders of this
corporation are granted subject to this reservation.

                  ARTICLE 11. LIMITATION OF DIRECTOR LIABILITY

         To the full extent that the Washington Business Corporation Act, as it
exists on the date hereof or may hereafter be amended, permits the limitation or
elimination of the liability of Directors, a Director of this corporation will
not be liable to this corporation or its shareholders for monetary damages for
conduct as a Director. Any amendments to or repeal of this Article 11 will not
adversely affect any right or protection of a Director of this corporation for
or with respect to any acts or omissions of such Director occurring prior to
such amendment or repeal.

                  ARTICLE 12. SPECIAL MEETINGS OF SHAREHOLDERS

         The Chairman of the Board of Directors, the President or the Board of
Directors may call special meetings of the shareholders for any purpose.
Further, a special meeting of the shareholders will be held if the holders of
not less than 10% of all the votes entitled to be cast on any issue proposed to
be considered at such special meeting have dated, signed and delivered to the
Secretary of this corporation one or more written demands for such meeting,
describing the purpose or purposes for which it is to be held, provided,
however, that upon qualification of the corporation as a "public company" under
Title 23B RCW the percentage of votes required to call a special meeting will be
50%.

                     ARTICLE 13. SPECIAL VOTING REQUIREMENTS

                    ADVANCED DIGITAL INFORMATION CORPORATION

                               SECTION 1. OFFICES

         The principal office of the corporation is its principal place of
business or such other place as the corporation's Board of Directors (the
"Board") may designate. The corporation may have such other offices, either
within or without the state of Washington, as the Board may designate or as the
business of the corporation may require from time to time.

                             SECTION 2. SHAREHOLDERS

2.1      ANNUAL MEETING

         The annual meeting of the shareholders shall be held each year within
90 to 180 days after the fiscal year end of the corporation at a date, time and
location determined by resolution of the Board of Directors, for the purpose of
electing Directors and transacting such other business as may properly come
before the meeting. At any time prior to the commencement of the annual meeting,
the Board may postpone the annual meeting for a period of up to one hundred
twenty 120 days from the date fixed for such meeting in accordance with this
subsection 2.1.

2.2      SPECIAL MEETINGS

         The Chairman of the Board, the President or the Board may call special
meetings of the shareholders for any purpose. Further, a special meeting of the
shareholders will be held if the holders of not less than 10% of all the votes
entitled to be cast on any issue proposed to be considered at such special
meeting have dated, signed and delivered to the Secretary one or more written
demands for such meeting, describing the purpose or purposes for which it is to
be held; provided, however, that upon qualification of the corporation as a
"public company" under Title 23B RCW the percentage of votes required to call a
special meeting will be 50%.

2.3      DATE, TIME AND PLACE OF MEETING

         Except as otherwise provided, all meetings of shareholders will be held
on such date and at such time and place within or without the state of
Washington as designated by the Board, by any persons entitled to call a meeting
hereunder or in a waiver of notice signed by all of the shareholders entitled to
notice of the meeting.

2.4      NOTICE OF MEETING

         Written notice stating the place, day and time of the meeting and, in
the case of a special meeting, the purpose or purposes for which the meeting is
called must be given by or at the direction of the Board, the Chairman of the
Board, the President or the Secretary to each 

                                      -1-
<PAGE>   7
shareholder entitled to notice of or to vote at the meeting not less than 10 nor
more than 60 days before the meeting, except that notice of a meeting to act on
an amendment to the Articles of Incorporation, a plan of merger or share
exchange, the sale, lease, exchange or other disposition of all or substantially
all of the corporation's assets other than in the regular course of business or
the dissolution of the corporation must be given not less than 20 nor more than
60 days before such meeting. Such notice may be transmitted by mail, private
carrier, personal delivery, telegraph, teletype or communications equipment
which transmits a facsimile of the notice to like equipment which receives and
reproduces such notice. If these forms of written notice are impractical in the
view of the Board, the Chairman of the Board, the President or the Secretary,
written notice may be transmitted by an advertisement in a newspaper of general
circulation in the area of the corporation's principal office. If such notice is
mailed, it will be deemed effective when deposited in the official government
mail, first-class postage prepaid, properly addressed to the shareholder at such
shareholder's address as it appears in the corporation's current record of
shareholders. Notice given in any other manner will be deemed effective when
dispatched to the shareholder's address, telephone number or other number
appearing on the records of the corporation. Any notice given by publication as
herein provided will be deemed effective five days after first publication.

2.5      BUSINESS FOR SHAREHOLDERS' MEETINGS

         2.5.1    BUSINESS AT ANNUAL MEETINGS

         In addition to the election of directors, other proper business may be
transacted at an annual meeting of shareholders, provided that such business is
properly brought before such meeting. To be properly brought before an annual
meeting, business must be (a) brought by or at the direction of the Board or (b)
brought before the meeting by a shareholder pursuant to written notice thereof,
in accordance with subsection 2.5.3 hereof, and received by the Secretary not
fewer than 60 nor more than 90 days prior to the date specified in subsection
2.1 hereof for such annual meeting (or, if less than 60 days' notice or prior
public disclosure of the date of the annual meeting is given or made to the
shareholders, not later than the tenth day following the day on which the notice
of the date of the annual meeting was mailed or such public disclosure was
made). Any such shareholder notice must set forth (i) the name and address of
the shareholder proposing such business; (ii) a representation that the
shareholder is entitled to vote at such meeting and a statement of the number of
shares of the corporation which are beneficially owned by such shareholder;
(iii) a representation that the shareholder intends to appear in person or by
proxy at the meeting to propose such business; and (iv) as to each matter the
shareholder 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, the language of the proposal (if appropriate), and
any material interest of the shareholder in such business. No business shall be
conducted at any annual meeting of shareholders except in accordance with this
subsection 2.5.1. If the facts warrant, the Board, or the chairman of an annual
meeting of shareholders, may determine and declare (a) that a proposal does not
constitute proper business to be transacted at the meeting or (b) that business
was not properly brought before the meeting in accordance with the provisions of
this subsection 2.5.1 and, if, in either case, it is so determined, any such
business shall not be transacted. The procedures set forth in this subsection
2.5.1 for business to be properly brought before an annual meeting by a
shareholder are in addition to, and 

                                      -2-
<PAGE>   8
not in lieu of, the requirements set forth in Rule 14a-8 under Section 14 of the
Securities Exchange Act of 1934, as amended, or any successor provision.

         2.5.2    BUSINESS AT SPECIAL MEETINGS

         At any special meeting of the shareholders, only such business as is
specified in the notice of such special meeting given by or at the direction of
the person or persons calling such meeting, in accordance with subsection 2.4
hereof, may come before such meeting.

         2.5.3    NOTICE TO CORPORATION

         Any written notice required to be delivered by a shareholder to the
corporation pursuant to subsection 2.2, subsection 2.5.1 or subsection 2.5.2
hereof must be given, either by personal delivery or by registered or certified
mail, postage prepaid, to the Secretary at the corporation's principal office.

2.6      WAIVER OF NOTICE

         Whenever any notice is required to be given to any shareholder under
the provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act ("WBCA"), 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.
Further, notice of the time, place and purpose of any meeting will be deemed to
be waived by any shareholder by attendance thereat in person or by proxy, unless
such shareholder at the beginning of the meeting objects to holding the meeting
or transacting business at the meeting.

2.7      FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS

         For the purpose of determining shareholders entitled (a) to notice of
or to vote at any meeting of shareholders or any adjournment thereof, (b) to
demand a special meeting, or (c) to receive payment of any dividend, or in order
to make a determination of shareholders for any other purpose, the Board may fix
in advance a date as the record date for any such determination. Such record
date may not be more than 70 days, and in case of a meeting of shareholders, may
not be less than 10 days prior to the date on which the particular action
requiring such determination is to be taken. If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting, the
record date shall be the day immediately preceding the date on which notice of
the meeting is first given to shareholders. Such a determination shall apply to
any adjournment of the meeting unless the Board fixes a new record date, which
it shall do if the meeting is adjourned to a date more than 120 days after the
date fixed for the original meeting. If no record date is fixed for the
determination of shareholders entitled to receive payment of any stock dividend

2.8      VOTING RECORD

         At least 10 days before each meeting of shareholders, a complete record
of the shareholders entitled to vote at such meeting, or any adjournment
thereof, shall be made, arranged by voting group and by each class or series of
shares therein, with the address of and number of shares held by each
shareholder. This record shall be kept on file at the registered office of the
corporation for 10 days prior to such meeting and shall be kept open at such
meeting for the inspection of any shareholder or any shareholder's agent.

2.9      QUORUM

         A majority of the votes entitled to be cast on a matter by the holders
of shares that, pursuant to the Articles of Incorporation or the WBCA, are
entitled to vote and be counted collectively upon such matter, represented in
person or by proxy, constitutes a quorum of such shares at a meeting of
shareholders. If less than a majority of such votes are represented at a
meeting, a majority of the votes so represented may adjourn the meeting from
time to time without further notice if the new date, time or place is announced
at the meeting before adjournment. Any business may be transacted at a
reconvened meeting that might have been transacted at the meeting as originally
called, provided a quorum is present or represented thereat. Once a share is
represented for any purpose at a meeting other than solely to object to holding
the meeting or transacting business thereat, it is deemed present for quorum
purposes for the remainder of the meeting and any adjournment thereof (unless a
new record date is or must be set for the adjourned meeting), notwithstanding
the withdrawal of enough shareholders to leave less than a quorum.

2.10     MANNER OF ACTING

         If a quorum is present, action on a matter other than the election of
Directors shall be approved if the votes cast in favor of the action by the
shares entitled to vote and be counted collectively upon such matter exceed the
votes cast against such action by the shares entitled to vote and be counted
collectively thereon, unless the Articles of Incorporation or the WBCA requires
a greater number of affirmative votes.

2.11     PROXIES

         A shareholder may vote by proxy executed in writing by the shareholder
or by his or her attorney-in-fact or agent or other officer or agent authorized
to tabulate votes. Such proxy is effective when received by the Secretary of the
corporation before or at the time of the meeting. A proxy becomes invalid 11
months after the date of its execution, unless otherwise provided in the proxy.
A proxy with respect to a specified meeting entitles the holder thereof to vote
at any reconvened meeting following adjournment of such meeting, but is not
valid after the final adjournment thereof.

2.12     VOTING OF SHARES

         Except as provided in the Articles of Incorporation or in Section 2.13
hereof, each outstanding share entitled to vote with respect to the subject
matter of an issue submitted to a meeting of shareholders is entitled to one
vote upon each such issue.

2.13     VOTING FOR DIRECTORS

         Each shareholder entitled to vote at an election of Directors may vote,
in person or by proxy, the number of shares owned by such shareholder for as
many persons as there are Directors to be elected and for whose election such
shareholder has a right to vote.

2.14     ACTION BY SHAREHOLDERS WITHOUT A MEETING

         Any action which could be taken at a meeting of the shareholders may be
taken without a meeting if a written consent setting forth the action so taken
is signed by all shareholders entitled to vote with respect to the subject
matter thereof. If not otherwise fixed by the Board, the record date for
determining shareholders entitled to take action without a meeting is the date
the first shareholder signs the consent. A shareholder may withdraw a consent
only by delivering a written notice of withdrawal to the corporation prior to
the time that all consents are in the possession of the corporation. Action
taken by written consent of shareholders without a meeting is effective when all
consents are in the possession of the corporation, unless the consent specifies
a later effective date. Any such consent shall be inserted in the minute book as
if it were the minutes of a meeting of the shareholders.

                          SECTION 3. BOARD OF DIRECTORS

3.1      GENERAL POWERS

         All corporate powers shall be exercised by or under the authority of,
and the business and affairs of the corporation shall be managed under the
direction of, the Board, except as may be otherwise provided in these Bylaws,
the Articles of Incorporation or the WBCA.

3.2      NUMBER AND TENURE

         The Board shall be composed of not less than two nor more than eight
Directors, the specific number to be set by resolution of the Board, provided
that the Board may be less than such number until vacancies are filled. No
decrease in the number of Directors shall have the effect of shortening the term
of any incumbent Director.

         The Board will be divided into three classes, with said classes to be
as equal in number as is possible. At the first election of Directors to such
classified Board, each Class 1 Director will be elected to serve until the next
ensuing annual meeting of shareholders, each Class 2 Director will be elected to
serve until the second ensuing annual meeting of shareholders and each Class 3
Director will be elected to serve until the third ensuing annual meeting of
shareholders. At each annual meeting of shareholders following the meeting at
which the Board is initially classified, the number of Directors equal to the
number of Directors in the class whose term expires at the time 

                                      -5-

<PAGE>   11
of such meeting will be elected to serve until the third ensuing annual meeting
of shareholders. Notwithstanding any of the foregoing provisions of this Section
3.2, Directors will serve until their successors are elected and qualified or
until their earlier death, resignation or removal from office or until there is
a decrease in the number of Directors. Directors need not be shareholders of the
corporation or residents of the state of Washington and need not meet any other
qualifications.

3.3      NOMINATION AND ELECTION

         3.3.1    NOMINATION

         Only persons who are nominated in accordance with the following
procedures are eligible for election as Directors. Nominations for the election
of Directors may be made (a) by or at the direction of the Board or (b) by any
shareholder of record entitled to vote for the election of Directors at such
meeting provided that such shareholder provides written notice (in accordance
with subsection 2.5.3 hereof) of such shareholder's intention to make such
nomination to the Secretary not later than (i) with respect to an election to be
held at an annual meeting of the shareholders, not fewer than 60 nor more than
90 days prior to the date specified in subsection 2.1 hereof for such annual
meeting (or if less than 60 days' notice or prior public disclosure of the date
of such annual meeting is given or made to the shareholders, not later than the
tenth day following the day on which such notice of the date of the annual
meeting was mailed or such public disclosure was made) and (ii) with respect to
an election to be held at a special meeting of the shareholders for the election
of Directors, the close of business on the seventh business day following the
date on which notice of such meeting is first given to shareholders. Any such
shareholder's notice must set forth (a) the name and address of the shareholder
who intends to make a nomination; (b) a representation that the shareholder is
entitled to vote at such meeting and a statement of the number of shares of the
corporation which are beneficially owned by such shareholder; (c) a
representation that the shareholder intends to appear in person or by proxy at
the meeting to nominate the person or persons specified in the notice; (d) as to
each person the shareholder proposes to nominate for election or re-election as
a Director, the name and address of such person and such other information
regarding such nominee as would be required in a proxy statement filed pursuant
to the proxy rules of the Securities and Exchange Commission had such nominee
been nominated by the Board, and a description of any arrangements or
understandings, between the shareholder and such nominee and any other persons
(including their names), pursuant to which the nomination is to be made; and (e)
the consent of each such nominee to serve as a Director if elected. If the facts
warrant, the Board, or the chairman of a shareholders' meeting at which
Directors are to be elected, may determine that a nomination was not made in
accordance with the foregoing procedure and, if it is so determined, the
defective nomination shall be disregarded. The right of shareholders to make
nominations pursuant to the foregoing procedure is subject to the rights of the
holders of any class or series of stock having a preference over the Common
Stock as to dividends or upon liquidation. The procedures set forth in this
subsection 3.3 for nomination for the election of Directors by shareholders are
in addition to, and not in limitation of, any procedures now in effect or
hereafter adopted by or at the direction of the Board or any committee thereof.

6.3      STOCK RECORDS

         The stock transfer books shall be kept at the registered office or
principal place of business of the corporation or at the office of the
corporation's transfer agent or registrar. The name and address of each person
to whom certificates for shares are issued, together with the class and number
of shares represented by each such certificate and the date of issue thereof,
shall be entered on the stock transfer books of the corporation. The person in
whose name shares stand on the books of the corporation shall be deemed by the
corporation to be the owner thereof for all purposes.

6.4      RESTRICTION ON TRANSFER

         Except to the extent that the corporation has obtained an opinion of
counsel acceptable to the corporation that transfer restrictions are not
required under applicable securities laws, or has otherwise satisfied itself
that such transfer restrictions are not required, all certificates representing
shares of the corporation shall bear a legend on the face of the certificate, or
on the reverse of the certificate if a reference to the legend is contained on
the face, which reads substantially as follows: "The securities evidenced by
this certificate have not been registered under the Securities Act of 1933 or
any applicable state law, and no interest therein may be sold, distributed,
assigned, offered, pledged or otherwise transferred unless (a) there is an
effective registration statement under such Act and applicable state securities
laws covering any such transaction involving said securities or (b) this
corporation receives an opinion of legal counsel for the holder of these
securities (concurred in by legal counsel for this corporation) stating that
such transaction is exempt from registration or this corporation otherwise
satisfies itself that such transaction is exempt from registration. Neither the
offering of the securities nor any offering materials have been reviewed by any
administrator under the Securities Act of 1933, or any applicable state law."

6.5      TRANSFER OF SHARES

         The transfer of shares of the corporation shall be made only on the
stock transfer books of the corporation pursuant to authorization or document of
transfer made by the holder of record thereof or by his or her legal
representative, who shall furnish proper evidence of authority to transfer, or
by his or her attorney-in-fact authorized by power of attorney duly executed and
filed with the Secretary of the corporation. All certificates surrendered to the
corporation for transfer shall be cancelled and no new certificates shall be
issued until the former certificates for a like number of shares shall have been
surrendered and cancelled.

6.6      LOST OR DESTROYED CERTIFICATES

         In the case of a lost, destroyed or mutilated certificate, a new
certificate may be issued therefor upon such terms and indemnity to the
corporation as the Board may prescribe.

                          SECTION 7. BOOKS AND RECORDS

                           SECTION 10. INDEMNIFICATION

10.1     RIGHT TO INDEMNIFICATION

         Each person who was, is or is threatened to be made a named party to or
is otherwise involved (including, without limitation, as a witness) in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative and whether formal or informal
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
Director or officer of the corporation or, that being or having been such a
Director or officer or an employee of the corporation, he or she is or was
serving at the request of the corporation as a Director, officer, partner,
trustee, employee or agent of another corporation or of a partnership, joint
venture, trust, employee benefit plan or other enterprise (hereinafter an
"indemnitee"), whether the basis of a proceeding is alleged action in an
official capacity as such a Director, officer, partner, trustee, employee or
agent or in any other capacity while serving as such a Director, officer,
partner, trustee, employee or agent, shall be indemnified and held harmless by
the corporation against all expense, liability and loss (including counsel fees,
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) actually and reasonably incurred or suffered by such indemnitee in
connection therewith, and such indemnification shall continue as to an
indemnitee who has ceased to be a Director, officer, partner, trustee, employee
or agent and shall inure to the benefit of the indemnitee's heirs, executors and
administrators. Except as provided in subsection 10.2 of this Section with
respect to proceedings seeking to enforce rights to indemnification, the
corporation shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if a proceeding (or part
thereof) was authorized or ratified by the Board. The right to indemnification
conferred in this Section 10.1 shall be a contract right.

10.2     RESTRICTIONS ON INDEMNIFICATION

         No indemnification shall be provided to any such indemnitee for acts or
omissions of the indemnitee finally adjudged to be intentional misconduct or a
knowing violation of law, for conduct of the indemnitee finally adjudged to be
in violation of Section 23B.08.310 of the Washington Business Corporation Act,
for any transaction with respect to which it was finally adjudged that such
indemnitee personally received a benefit in money, property or services to which
the indemnitee was not legally entitled or if the corporation is otherwise
prohibited by applicable law from paying such indemnification, except that if
Section 23B.08.560 or any successor provision of the WBCA is hereafter amended,
the restrictions on indemnification set forth in this subsection 10.2 shall be
as set forth in such amended statutory provision.

10.3     ADVANCEMENT OF EXPENSES

         The right to indemnification conferred in this Section shall include
the right to be paid by the corporation the expenses incurred in defending any
proceeding in advance of its final disposition (hereinafter an "advancement of
expenses"). An advancement of expenses shall be made upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of
such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by 

                                      -17-
<PAGE>   23
final judicial decision from which there is no further right to appeal that such
indemnitee is not entitled to be indemnified for such expenses under this
subsection 10.3.

10.4     RIGHT OF INDEMNITEE TO BRING SUIT

         If a claim under subsection 10.1 or 10.3 of this Section is not paid in
full by the corporation within 60 days after a written claim has been received
by the corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be 20 days, the indemnitee
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim. If successful in whole or in part, in any such suit
or in a suit brought by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of prosecuting or defending such suit. The indemnitee
shall be presumed to be entitled to indemnification under this Section upon
submission of a written claim (and, in an action brought to enforce a claim for
an advancement of expenses, where the required undertaking has been tendered to
the corporation) and thereafter the corporation shall have the burden of proof
to overcome the presumption that the indemnitee is so entitled.

10.5     PROCEDURES EXCLUSIVE

         Pursuant to Section 23B.08.560(2) or any successor provision of the
WBCA, the procedures for indemnification and advancement of expenses set forth
in this Section are in lieu of the procedures required by Section 23B.08.550 or
any successor provision of the WBCA.

10.6     NONEXCLUSIVITY OF RIGHTS

         The right to indemnification and the advancement of expenses conferred
in this Section shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of the Articles of
Incorporation or Bylaws of the corporation, general or specific action of the
Board, contract or otherwise.

10.7     INSURANCE, CONTRACT AND FUNDING

         The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, partner, trustee, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the WBCA. The corporation may enter into contracts with
any Director, officer, partner, trustee, employee or agent of the corporation in
furtherance of the provisions of this Section and may create a trust fund, grant
a security interest or use other means (including, without limitation, a letter
of credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Section.

10.8     INDEMNIFICATION OF EMPLOYEE AND AGENT OF THE CORPORATION

         The corporation may, by action of the Board, grant rights to
indemnification and advancement of expenses to employees and agents or any class
or group of employees and agents 

                                      -18-
<PAGE>   24
of the corporation (i) with the same scope and effect as the provisions of this
Section with respect to the indemnification and advancement of expenses of
Directors and officers of the corporation; (ii) pursuant to rights granted
pursuant to, or provided by, the WBCA; or (iii) otherwise consistent with law.

10.9     PERSON SERVING OTHER ENTITIES

         Any person who, while a Director, officer or employee of the
corporation, is or was serving (a) as a Director or officer of another foreign
or domestic corporation of which a majority of the-shares entitled to vote in
the election of its Directors is held by the corporation, or (b) as a partner,
trustee or otherwise in an executive or management capacity in a partnership,
joint venture, trust or other enterprise of which the corporation or a wholly
owned subsidiary of the corporation is a general partner or has a majority
ownership shall be deemed to be so serving at the request of the corporation and
entitled to indemnification and advancement of expenses under subsections 10.1
and 10.3 of this Section.

                             SECTION 11. AMENDMENTS

         These Bylaws may be altered, amended or repealed and new Bylaws may be
adopted by the Board, subject to approval by a majority of the Continuing
Directors (as defined in the Articles of Incorporation). The shareholders may
also alter, amend and repeal these Bylaws or adopt new Bylaws by the affirmative
vote of the holders of not less than two-thirds of the outstanding shares.

                                RIGHTS AGREEMENT


         RIGHTS AGREEMENT dated as of August 12, 1996, between ADVANCED DIGITAL
INFORMATION CORPORATION, a Washington corporation (the "Company"), and
CHASEMELLON SHAREHOLDER SERVICES, L.L.C., as Rights Agent (the "Rights Agent").

         The Board of Directors of the Company has authorized and declared a
dividend of one Right (as hereinafter defined) for each share of Common Stock,
no par value, of the Company (the "Common Stock") outstanding at the Close of
Business (as hereinafter defined) on the date of the closing of the Spinoff (as
hereinafter defined) (the "Record Date") and has further authorized the issuance
of one Right (as such number may hereafter be adjusted pursuant to the
provisions of this Rights Agreement) with respect to each share of Common Stock
that shall become outstanding between the Record Date and the earliest of the
Distribution Date, the Redemption Date and the Expiration Date (as such terms
are hereinafter defined); provided, however, that Rights may be issued with
respect to shares of Common Stock that shall become outstanding after the
Distribution Date and prior to the earlier of the Redemption Date and the
Expiration Date in accordance with the provisions of Section 23. Each Right
shall initially represent the right to purchase one one-hundredth (1/100th) of a
share of Series A Participating Cumulative Preferred Stock, no par value, of the
Company (the "Preferred Shares"), having the powers, rights and preferences set
forth in the Designation of Rights and Preferences (as hereinafter defined)
attached as Exhibit A.

         Accordingly, in consideration of the premises and the mutual agreements
set forth in this Rights Agreement, the Company and the Rights Agent hereby
agree as follows:

SECTION 1.       CERTAIN DEFINITIONS

         For purposes of this Rights Agreement, the following terms have the
meanings indicated:

         "Acquiring Person" shall mean any Person (as hereinafter defined)
which, alone or together with all Affiliates and Associates (as such terms are
hereinafter defined) of such Person, shall be the Beneficial Owner (as
hereinafter defined) of 15% or more of the Common Stock (as hereinafter defined)
then outstanding, but shall not include the Company, any Subsidiary (as
hereinafter defined) of the Company, any employee benefit plan of the Company or
of any of its Subsidiaries, or any Person holding Common Stock for or pursuant
to the terms of any such employee benefit plan. Notwithstanding the foregoing,
no Person shall become an "Acquiring Person" as the result of an acquisition of
Common Stock by the Company which, by reducing the number of shares outstanding,
increases the proportionate number of shares beneficially owned by such Person
to 15% or more of the Common Stock of the Company then outstanding; provided,
however, that if a Person shall become the Beneficial Owner of 15% or more of
the Common Stock then outstanding by reason of share purchases by the Company
and shall, after such share purchases by the Company, become the 

                                      -1-
<PAGE>   5
Beneficial Owner of any additional Common Stock, then such Person shall be
deemed to be an "Acquiring Person." Notwithstanding the foregoing, if the Board
of Directors of the Company determines in good faith that a Person which would
otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph, has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of Common Shares so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph, then such Person shall not be deemed to
be an "Acquiring Person" for any purposes of this Agreement.

         "Affiliate" and "Associate," when used with reference to any Person,
shall have the respective meanings ascribed to such terms in Rule 12b-2 of the
General Rules and Regulations under the Exchange Act (as hereinafter defined),
as in effect on the date of this Rights Agreement.

         A Person shall be deemed to be the "Beneficial Owner" of, to
"beneficially own," and to have "Beneficial Ownership" of, any securities:

                  (a)      that such Person or any of such Person's Affiliates
or Associates is deemed to "beneficially own" within the meaning of Rule 13d-3
of the General Rules and Regulations under the Exchange Act, as in effect on the
date of this Rights Agreement;

                  (b)      that such Person or any of such Person's Affiliates
or Associates have (i) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding (written or oral), or upon the exercise of
conversion rights, exchange rights, rights (other than the Rights), warrants or
options, or otherwise; provided, however, that a Person shall not be deemed to
be the Beneficial Owner of, to beneficially own, or to have Beneficial Ownership
of, securities tendered pursuant to a tender or exchange offer made by or on
behalf of such Person or any of such Person's Affiliates or Associates until
such tendered securities are accepted for purchase or exchange thereunder or
(ii) the right to vote pursuant to any agreement, arrangement or understanding
(written or oral); provided, however, that a Person shall not be deemed to be
the Beneficial Owner of, to beneficially own, or to have Beneficial Ownership
of, any security if (A) the agreement, arrangement or understanding (written or
oral) to vote such security arises solely from a revocable proxy or consent
given to such Person in response to a public proxy or consent solicitation made
pursuant to, and in accordance with, the applicable rules and regulations under
the Exchange Act and (B) the beneficial ownership of such security is not also
then reportable on Schedule 13D under the Exchange Act (or any comparable or
successor report); or

                  (c)      that are beneficially owned, directly or indirectly,
by any other Person with which such Person or any of such Person's Affiliates or
Associates has any agreement, arrangement or understanding (written or oral) for
the purpose of acquiring, holding, voting (except pursuant to a revocable proxy
as described in clause (b)(ii) of this definition) or disposing of any
securities of the Company.

                                      -2-
<PAGE>   6
         Notwithstanding the foregoing, nothing contained in this definition
shall cause a Person ordinarily engaged in business as an underwriter of
securities to be the "Beneficial Owner" of, or to "beneficially own," any
securities acquired in a bona fide firm commitment underwriting pursuant to an
underwriting agreement with the Company.

         Notwithstanding anything in this definition of Beneficial Ownership to
the contrary, the phrase "then outstanding," when used with reference to a
Person's Beneficial Ownership of securities of the Company, shall mean the
number of such securities then issued and outstanding together with the number
of such securities not then actually issued and outstanding which such Person
would be deemed to own beneficially hereunder.

         "Book Value," when used with reference to Common Shares (as hereinafter
defined) issued by any Person, shall mean the amount of such Person's equity
applicable to each Common Share, determined (a) in accordance with generally
accepted accounting principles in effect on the date as of which such Book Value
is to be determined, (b) using all the consolidated assets and all the
consolidated liabilities of such Person on the date as of which such Book Value
is to be determined, except that no value shall be included in such assets for
goodwill arising from consummation of a business combination, and (c) after
giving effect to (i) the exercise of all rights, options and warrants to
purchase such Common Shares (other than the Rights), and the conversion of all
securities convertible into such Common Shares, at an exercise or conversion
price, per Common Share, that is less than such Book Value before giving effect
to such exercise or conversion (whether or not exercisability or convertibility
is conditioned upon occurrence of a future event), (ii) all dividends and other
distributions on the capital stock of such Person declared prior to the date as
of which such Book Value is to be determined and to be paid or made after such
date, and (iii) any other agreement, arrangement or understanding (written or
oral), or transaction or other action prior to the date as of which such Book
Value is to be determined that would have the effect of thereafter reducing such
Book Value.

         "Business Combination" shall have the meaning set forth in Section
11(d)(i).

         "Business Day" shall mean any day other than a Saturday, Sunday or a
day on which banking institutions in New York, New York, or Seattle, Washington,
are authorized or obligated by law or executive order to close.

         "Close of Business" on any given date shall mean 5 p.m., New York City
time, on such date; provided, however, that if such date is not a Business Day,
"Close of Business" shall mean 5 p.m., New York City time, on the next
succeeding Business Day.

         "Common Shares," when used with reference to the Company prior to a

         The Company hereby appoints the Rights Agent to act as agent for the

conditions of this Rights Agreement, and the Rights Agent hereby accepts such
appointment. The Company may from time to time appoint one or more co-Rights
Agents as it may deem necessary or desirable (the term "Rights Agent" being used
in this Rights Agreement to refer, collectively, to the Rights Agent together
with any such co-Rights Agents). In the event the Company appoints one or more

SECTION 3.            ISSUE OF RIGHTS AND RIGHT CERTIFICATES

         (a) One Right shall be associated with each share of Common Stock

become outstanding between the Record Date and the earliest of the Distribution
Date, the Redemption Date and 

                                      -7-
<PAGE>   11
the Expiration Date and each additional share of Common Stock with which Rights
are issued after the Distribution Date but prior to the earlier of the
Redemption Date and the Expiration Date as provided in Section 23; provided,
however, that if the number of outstanding Rights are combined into a smaller
number of outstanding Rights pursuant to Section 12(a), the appropriate
fractional Right determined pursuant to such Section shall thereafter be
associated with each such share of Common Stock.

         (b) Until the earlier of (i) the Close of Business on the tenth
Business Day after the Shares Acquisition Date and (ii) the Close of Business on
such date, if any, as may be designated by the Company's Board of Directors
following the commencement of, or first public disclosure of an intent to
commence, a tender or exchange offer by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any of
its Subsidiaries, or any Person holding Common Stock for or pursuant to the
terms of any such employee benefit plan) for outstanding Common Stock, if upon
consummation of such tender or exchange offer such Person could be the
Beneficial Owner of 15% or more of the outstanding Common Stock (the Close of
Business on the earlier of such dates being the "Distribution Date"), (y) the
Rights will be evidenced by the certificates for Common Stock registered in the
names of the holders thereof and not by separate Right Certificates and (z) the
Rights, including the right to receive Right Certificates, will be transferable
only in connection with the transfer of Common Stock. As soon as practicable
after the Distribution Date, the Company will prepare and execute, the Rights
Agent will countersign, and the Company will send or cause to be sent (and the
Rights Agent, if requested, will send), by first-class, postage-prepaid mail, to
each record holder of Common Stock as of the Distribution Date, at the address
of such holder shown on the records of the Company, a Right Certificate
evidencing one whole Right for each share of Common Stock (or for the number of
shares of Common Stock with which one whole Right is then associated if the
number of Rights per share of Common Stock held by such record holder has been
adjusted in accordance with the proviso in Section 3(a)). If the number of
Rights associated with each share of Common Stock has been adjusted in
accordance with the proviso in Section 3(a), at the time of distributing the
Right Certificates the Company may make any necessary and appropriate rounding
adjustments so that Right Certificates representing only whole numbers of Rights
are distributed and cash is paid in lieu of any fractional Right in accordance
with Section 15(a). As of and after the Distribution Date, the Rights will be
evidenced solely by such Right Certificates.

         (c) Certificates representing Common Stock issued after the Record Date
(including, without limitation, upon transfer or exchange of outstanding Common
Stock), but prior to the earliest of the Distribution Date, the Redemption Date
and the Expiration Date, shall have printed on, written on or otherwise affixed
to them the following legend:

                  This certificate also evidences and entitles the holder hereof
         to certain rights as set forth in the Rights Agreement dated as of
         August 12, 1996, as it may be amended from time to time (the "Rights
         Agreement"), between Advanced Digital Information Corporation ("ADIC")
         and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (or
         between ADIC and any successor Rights Agent under the Rights
         Agreement), the terms of which are 

                                      -8-
<PAGE>   12
        hereby incorporated herein by reference and a copy of which is on file
        at the principal executive offices of ADIC. Under certain circumstances,
        as set forth in the Rights Agreement, such Rights will be evidenced by
        separate certificates and will no longer be evidenced by this
        certificate. ADIC will mail to the holder of this certificate a copy of
        the Rights Agreement without charge after receipt of a written request
        therefor. Rights beneficially owned by Acquiring Persons or their
        Affiliates or Associates thereof (as such terms are defined in the
        Rights Agreement) and by any subsequent holder of such Rights are null
        and void and nontransferable.

Notwithstanding the requirements of this paragraph (c), the omission of a legend
shall not affect the enforceability of any part of this Rights Agreement or the
rights of any holder of Rights.

SECTION 4.            FORM OF RIGHT CERTIFICATES

         The Right Certificates (and the form of election to purchase and form
of assignment to be printed on the reverse side thereof) shall be in
substantially the form set forth as Exhibit B and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Rights Agreement, or as may be required to comply
with any applicable law or with any rule or regulation made pursuant thereto or
with any rule or regulation of any stock exchange on which the Rights may from
time to time be listed, or to conform to usage. Subject to the provisions of
Sections 7, 11 and 23, the Right Certificates, whenever issued, shall be dated
as of the Distribution Date, and on their face shall entitle the holders thereof
to purchase such number of Preferred Shares as shall be set forth therein for
the Purchase Price set forth therein.

SECTION 5.            EXECUTION, COUNTERSIGNATURE AND REGISTRATION

         (a) The Right Certificates shall be executed on behalf of the Company
by the Chairman of the Board of Directors, the Chief Executive Officer, the
President, the Chief Operating Officer, the Chief Financial Officer or a Vice
President (whether preceded by any additional title) of the Company, either
manually or by facsimile signature, shall have affixed thereon the Company's
seal or a facsimile thereof, and shall be attested by the Secretary, an
Assistant Secretary or a Vice President (whether preceded by any additional
title, provided that such Vice President shall not have also executed the Right
Certificates) of the Company, either manually or by facsimile signature. The
Right Certificates shall be manually countersigned by the Rights Agent and shall
not be valid for any purpose unless so countersigned. In case any officer of the
Company who shall have signed any of the Right Certificates shall cease to be
such an officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates may nevertheless
be countersigned by the Rights Agent and issued and delivered by the Company
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such an officer of the Company; and any Right
Certificate may be signed on behalf of the Company by any person who, at the
actual date of execution of such Right 

                                      -9-
<PAGE>   13
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of execution of this Rights Agreement any such
person was not such an officer of the Company.

         (b) Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal office in Seattle, Washington, books for
registration and transfer of the Right Certificates issued under this Rights
Agreement. Such books shall show the names and addresses of the respective
holders of the Right Certificates, the number of Rights evidenced by each Right
Certificate, the certificate number of each Right Certificate and the date of
each Right Certificate.

SECTION6.         TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHT
                  CERTIFICATES; LOST, STOLEN, DESTROYED OR MUTILATED RIGHT
                  CERTIFICATES; UNCERTIFICATED RIGHTS

         (a) Subject to the provisions of Sections 7(e) and 15, at any time
after the Distribution Date, and at or prior to the Close of Business on the
earlier of the Redemption Date and the Expiration Date, any Right Certificate or
Right Certificates may be transferred, split up, combined or exchanged for
another Right Certificate or Right Certificates (other than Right Certificates
representing Rights that have become void pursuant to Section 7(e) or that have
been exchanged pursuant to Section 11(b), entitling the registered holder to
purchase a like number of one one-hundredths (1/100th) of a Preferred Share as
the Right Certificate or Right Certificates surrendered then entitled such
holder to purchase. Any registered holder desiring to transfer, split up,
combine or exchange any Right Certificate or Right Certificates shall make such
request in writing delivered to the Rights Agent and shall surrender the Right
Certificate or Right Certificates to be transferred, split up, combined or
exchanged at the principal office of the Rights Agent; provided, however, that
neither the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any Right Certificate surrendered for
transfer until the registered holder shall have completed and signed the
certification contained in the form of assignment on the reverse side of such
Right Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to the provisions of Sections 7(e) and 15, countersign and
deliver to the Person entitled thereto a Right Certificate or Right
Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer, split-up, combination or exchange of
Right Certificates.

         (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a valid Right Certificate, and, in case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to them, and, at the Company's
request, reimbursement to the Company and the Rights Agent of all reasonable
expenses incidental thereto, and upon surrender to the Rights Agent and
cancellation of the Right Certificate if mutilated, the Company will make a new
Right Certificate of like tenor and deliver such new Right Certificate to the
Rights Agent for 

                                      -10-
<PAGE>   14
delivery to the registered holder in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated.

         (c) Notwithstanding any other provision of this Rights Agreement, the
Company and the Rights Agent may amend this Rights Agreement to provide for
uncertificated Rights in addition to or in place of Rights evidenced by Right
Certificates.

SECTION 7.            EXERCISE OF RIGHTS; EXPIRATION DATE OF RIGHTS

         (a) Subject to Section 7(e) and except as otherwise provided in this

or prior to the earlier of (i) the Close of Business on the tenth year
anniversary of the Record Date (the Close of Business on such date being the
"Expiration Date") and (ii) the Redemption Date, one one-hundredth (1/100th) of
a Preferred Share, subject to adjustment from time to time as provided in
Sections 11 and l2.

         (b) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided in this Rights Agreement)
in whole or in part at any time after the Distribution Date, upon surrender of
the Right Certificate, with the form of election to purchase on the reverse side
thereof duly executed, to the Rights Agent at the principal office of the Rights
Agent in Seattle, Washington, together with payment of the Purchase Price for
each one one-hundredth (1/100th) of a Preferred Share as to which the Rights are
exercised, at or prior to the earliest of (i) the Expiration Date, (ii) the
Redemption Date, and (iii) the time at which such Rights are exchanged as
provided in Section 11(b).

         (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the Preferred Shares to be purchased together
with an amount equal to any applicable transfer tax, by certified check,
cashier's check or money order payable to the order of the Company, the Rights
Agent shall thereupon (i) either (A) promptly requisition from any transfer
agent of the Preferred Shares (or make available, if the Rights Agent is the
transfer agent) certificates for the number of Preferred Shares to be purchased
and the Company hereby irrevocably authorizes its transfer agent to comply with
all such requests or (B) if the Company shall have elected to deposit the
Preferred Shares with a depositary agent under a depositary arrangement,
promptly requisition from the depositary agent depositary receipts representing
the number of one one-hundredths (1/100ths) of a Preferred Share to be purchased
(in which case certificates for the Preferred Shares to be represented by such
receipts shall be deposited by the transfer agent with the depositary agent) and
the Company will direct the depositary agent to comply with all such requests,
(ii) when appropriate, promptly requisition from the Company the amount of cash
to be paid in lieu of the issuance of fractional shares in accordance with
Section 15, (iii) promptly after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered

Certificate.

                                      -11-
<PAGE>   15
         (d) In case the registered holder of any Right Certificate shall
exercise fewer than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and delivered to the registered holder of such Right
Certificate or to his or her duly authorized assigns, subject to the provisions
of Section 15.

         (e) If the Rights are at any time beneficially owned by an Acquiring
Person or an Affiliate or Associate of an Acquiring Person, such Rights shall be
null and void and nontransferable and the holder of any such Right (including
any purported transferee or subsequent holder) shall not have any right to
exercise or transfer any such Right. No Right Certificate shall be issued at any
time upon the transfer of any Rights to an Acquiring Person whose Rights would
be void pursuant to the preceding sentence or any Associate or Affiliate thereof
or to any nominee of such Acquiring Person, Associate or Affiliate; and any
Right Certificate delivered to the Rights Agent for transfer to an Acquiring
Person whose Rights would be void pursuant to the preceding sentence shall be
canceled.

         (f) Notwithstanding anything in this Rights Agreement to the contrary,
neither the Rights Agent nor the Company shall be obligated to undertake any
action with respect to a registered holder of any Right Certificates upon the
occurrence of any purported exercise as set forth in this Section 7 unless such
registered holder shall have (i) completed and signed the certificate contained
in the form of election to purchase set forth on the reverse side of the Right
Certificate surrendered for such exercise and (ii) provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company shall reasonably request.

         (g) The Company may temporarily suspend, for a period of time not to
exceed 90 calendar days after the Distribution Date, the exercisability of the
Rights in order to prepare and file a registration statement under the
Securities Act, on an appropriate form, with respect to the Preferred Shares
purchasable upon exercise of the Rights and permit such registration statement
to become effective; provided, however, that no such suspension shall remain
effective after, and the Rights shall without any further action by the Company
or any other Person become exercisable immediately upon, the effectiveness of
such registration statement. Upon any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended and shall issue a further public announcement at such time
as the suspension is no longer in effect. Notwithstanding any provision in this
Rights Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction if the requisite qualification under the blue sky or securities
laws of such jurisdiction shall not have been obtained or the exercise of the
Rights shall not be permitted under applicable law.

SECTION 8.            CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES

         All Right Certificates surrendered or presented for the purpose of
exercise, transfer, split-up, combination or exchange shall, and any Right
Certificate surrendered or presented for any purpose that represents Rights that
have become null and void and nontransferable 

                                      -12-
<PAGE>   16

any of its agents, be delivered to the Rights Agent for cancellation or in
canceled form, or, if surrendered or presented to the Rights Agent, shall be
canceled by it, and no Right Certificates shall be issued in lieu thereof except
as expressly permitted by this Rights Agreement. The Company shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any Right Certificate purchased or acquired by the Company.
The Rights Agent shall deliver all canceled Right Certificates to the Company,
or shall, at the Company's written request, destroy such canceled Right
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

SECTION 9.            RESERVATION AND AVAILABILITY OF PREFERRED SHARES

         (a) The Company covenants and agrees that it will cause to be reserved
and kept available out of its authorized and unissued Preferred Shares or any
authorized and issued Preferred Shares held in its treasury, free from
preemptive rights or any right of first refusal, a number of Preferred Shares
sufficient to permit the exercise in full of all outstanding Rights.

         (b) In the event that there shall not be sufficient Preferred Shares
issued but not outstanding, or authorized but unissued, to permit the exercise
or exchange of Rights in accordance with Section 11, the Company covenants and
agrees that it will take all such action as may be necessary to authorize
additional Preferred Shares for issuance upon the exercise or exchange of Rights
pursuant to Section 11.

         (c) The Company covenants and agrees that it will take all such action
as may be necessary to ensure that all Preferred Shares delivered upon exercise
or exchange of Rights shall, at the time of delivery of the certificates for
such Preferred Shares (subject to payment of the Purchase Price), be duly and
validly authorized and issued and fully paid and nonassessable shares.

         (d) So long as the Preferred Shares issuable upon the exercise or
exchange of Rights are to be listed on any national securities exchange, the
Company covenants and agrees to use its best efforts to cause, from and after
such time as the Rights become exercisable or exchangeable, all Preferred Shares
reserved for such issuance to be listed on such securities exchange upon
official notice of issuance upon such exercise or exchange.

         (e) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges that may be
payable in respect of the issuance or delivery of Right Certificates or of any
Preferred Shares upon the exercise or exchange of Rights. The Company shall not,
however, be required to pay any transfer tax that may be payable in respect of
any transfer or delivery of Right Certificates to a Person other than, or in
respect of the issuance or delivery of certificates representing the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or exchange or to issue
or deliver any certificates representing Preferred Shares upon the exercise or
exchange of any Rights until any such tax shall have been paid (any such tax
being payable by the holder of such Right Certificate at the time of 

                                      -13-
<PAGE>   17
surrender) or until it has been established to the Company's satisfaction that
no such tax is due.

SECTION 10.           PREFERRED SHARES RECORD DATE

         Each Person in whose name any certificate for Preferred Shares is
issued upon the exercise or exchange of Rights shall for all purposes be deemed
to have become the holder of record of the Preferred Shares represented thereby
on, and such certificate shall be dated, the date on which the Right Certificate
evidencing such Rights was duly surrendered and payment of any Purchase Price
(and any applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date on which the Preferred Shares
transfer books of the Company are closed, such Person shall be deemed to have
become the record holder of such Preferred Shares on, and such certificate shall
be dated, the next succeeding Business Day on which the Preferred Shares
transfer books of the Company are open. Prior to the exercise of the Rights
evidenced thereby, the holder of a Right Certificate shall not be entitled to
any rights of a holder of Preferred Shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

SECTION  11.      ADJUSTMENTS IN RIGHTS AFTER THERE IS AN ACQUIRING PERSON;
                  EXCHANGE OF RIGHTS FOR SHARES; BUSINESS COMBINATIONS

         (a) Upon a Person becoming an Acquiring Person, each holder of a Right,
except as provided in Section 7(e), shall thereafter have a right to receive,
upon exercise thereof for the Purchase Price in accordance with the terms of
this Rights Agreement, such number of shares of Common Stock as shall equal the
result obtained by multiplying the Purchase Price by a fraction, the numerator
of which is the number of one one-hundredths (1/100ths) of a Preferred Share for
which a Right is then exercisable and the denominator of which is 50% of the
Market Value of the Common Stock on the date on which a Person becomes an
Acquiring Person. As soon as practicable after a Person becomes an Acquiring
Person (provided the Company shall not have elected to make the exchange
permitted by Section 11(b)(i) for all outstanding Rights), the Company covenants
and agrees to use its best efforts to:

                  (i)      prepare and file a registration statement under the
         Securities Act, on an appropriate form, with respect to the securities
         purchasable upon exercise of the Rights;

                  (ii)     cause such registration statement to become effective
         as soon as practicable after such filing;

                  (iii)    cause such registration statement to remain effective
         (with a prospectus at all times meeting the requirements of the
         Securities Act) until the Expiration Date; and

                                      -14-
<PAGE>   18
                  (iv)     qualify or register the securities purchasable upon
         exercise of the Rights under the blue sky or securities laws of such
         jurisdictions as may be necessary or appropriate.

         (b)       (i) The Company's Board of Directors may, at its option, at 
         any time after a Person becomes an Acquiring Person, mandatorily
         exchange all or part of the then outstanding and exercisable Rights
         (which shall not include Rights that shall have become null and void
         and nontransferable pursuant to the provisions of Section 7(e)) for
         consideration per Right consisting of one-half of the Common Stock that
         would be issuable at such time upon the exercise of one Right in
         accordance with Section 11(a) (the consideration issuable per Right
         pursuant to this Section 11(b)(i) being the "Exchange Consideration").
         If the Company's Board of Directors elects to exchange all the Rights
         for the Exchange Consideration pursuant to this Section 11(b)(i) prior
         to the physical distribution of the Right Certificates, the Company may
         distribute the Exchange Consideration in lieu of distributing Right
         Certificates, in which case for purposes of this Rights Agreement
         holders of Rights shall be deemed to have simultaneously received and
         surrendered for exchange Right Certificates on the date of such
         distribution.

                  (ii)     Any action of the Company's Board of Directors
         ordering the exchange of any Rights pursuant to Section 11(b)(i) shall
         be irrevocable and, immediately upon the taking of such action and
         without any further action and without any notice, the right to
         exercise any such Right pursuant to Section 11(a) shall terminate and
         the only right thereafter of a holder of such Right shall be to receive
         the Exchange Consideration in exchange for each such Right held by such
         holder or, if the Exchange Consideration shall not have been paid, to
         exercise any such Right pursuant to Section 11(d)(i). The Company shall
         promptly give public notice of any such exchange; provided, however,
         that the failure to give, or any defect in, such notice shall not
         affect the validity of such exchange. The Company promptly shall mail a
         notice of any such exchange to all holders of such Rights at their last
         addresses as they appear on the registry books of the Rights Agent. Any
         notice that is mailed in the manner provided in this Rights Agreement
         shall be deemed given, whether or not the holder receives the notice.
         Each such notice of exchange will state the method by which the
         exchange of the Rights for the Exchange Consideration will be effected
         and, in the event of any partial exchange, the number of Rights that
         will be exchanged. Any partial exchange shall be effected pro rata
         based on the number of Rights (other than Rights that shall have become
         null and void and nontransferable pursuant to the provisions of Section
         7(e)) held by each holder of Rights.

         (c) In the event that there shall not be sufficient Common Stock issued
but not outstanding or authorized but unissued to permit the exercise in full of
the Rights in accordance with Section 11(a) or 11(b), the Company shall take all
such action as may be necessary to authorize additional Common Stock for
issuance upon exercise of the Rights. In the event the Company shall, after a
good-faith effort, be unable to take all such action as may be necessary to
authorize such additional Common Stock, the Company shall substitute, for each
Common Stock that would otherwise be issuable upon exercise of a Right, that
number 

                                      -15-
<PAGE>   19
of Preferred Shares or fraction thereof such that the current Market Value of
one Preferred Share multiplied by such number or fraction is equal to the
current Market Value of one share of Common Stock as of the date of issuance of
such Preferred Shares or fraction thereof.

         (d)     (i)      In the event that, following a Distribution Date, any
         transactions specified in the following clause (A), (B) or (C) of this
         Section 11(d)(i) (each such transaction being a "Business Combination")
         shall be consummated, directly or indirectly:

                  (A)      the Company shall consolidate with, or merge with and
         into, any other Person;

                  (B)      any Person shall consolidate with the Company, or
         merge with and into the Company and the Company shall be the continuing
         or surviving corporation following the merger and, in connection with
         such merger, all or part of the Common Stock shall be changed into or
         exchanged for capital stock or other securities of the Company or of
         any other Person (or the Company) or cash or any other property; or

                  (C)      the Company shall sell, lease, exchange or otherwise
         transfer or dispose of (or one or more of its Subsidiaries shall sell,
         lease, exchange or otherwise transfer or dispose of), in one or more
         transactions, the Major Part of the assets of the Company and its
         Subsidiaries (taken as a whole) to any other Person or Persons other
         than the Company or one or more of its wholly owned Subsidiaries,

         then, in each such case, proper provision shall be made so that each
         holder of a Right, except as provided in Section 7(e), shall thereafter
         have the right to receive, upon the exercise thereof for the Purchase
         Price in accordance with the terms of this Rights Agreement, the
         securities specified below (or, at such holder's option, if any
         Business Combination is consummated at any time after a Person becomes
         an Acquiring Person, the securities specified in Section 11(a)):

                  (1) If the Principal Party in such Business Combination has
         Registered Common Shares outstanding, each Right shall thereafter
         represent the right to receive, upon the exercise thereof for the
         Purchase Price in accordance with the terms of this Rights Agreement,
         such number of Registered Common Shares of such Principal Party, free
         and clear of all liens, encumbrances or other adverse claims, as shall
         have an aggregate Market Value equal to the result obtained by
         multiplying the Purchase Price by two; or

                  (2) If the Principal Party in such Business Combination does
         not have Registered Common Shares outstanding, each Right shall
         thereafter represent the right to receive, upon the exercise thereof
         for the Purchase Price in accordance with the terms of this Rights
         Agreement, at the election of the holder of such Right at the time of
         the exercise thereof, any of:

                                      -16-
<PAGE>   20
                  (x)      such number of Common Shares of the Surviving Person
         in such Business Combination as shall have an aggregate Book Value
         immediately after giving effect to such Business Combination equal to
         the result obtained by multiplying the Purchase Price by two;

                  (y)      such number of Common Shares of the Principal Party
         in such Business Combination (if the Principal Party is not also the
         Surviving Person in such Business Combination) as shall have an
         aggregate Book Value immediately after giving effect to such Business
         Combination equal to the result obtained by multiplying the Purchase
         Price by two; or

                  (z)      if the Principal Party in such Business Combination
         is an Affiliate of one or more Persons which has Registered Common
         Shares outstanding, such number of Registered Common Shares of
         whichever of such Affiliates of the Principal Party has Registered
         Common Shares with the greatest aggregate Market Value on the date of
         consummation of such Business Combination as shall have an aggregate
         Market Value on the date of such Business Combination equal to the
         result obtained by multiplying the Purchase Price by two.

         (ii)     The Company shall not consummate any Business Combination
unless each issuer of Common Shares for which Rights may be exercised, as set
forth in this Section 11(d), shall have sufficient authorized Common Shares that
have not been issued or reserved for issuance (and that shall, when issued upon
exercise thereof in accordance with this Rights Agreement, be validly issued,
fully paid and nonassessable and free of preemptive rights, rights of first
refusal or any other restrictions or limitations on the transfer or ownership
thereof) to permit the exercise in full of the Rights in accordance with this
Section 11(d) and unless prior thereto:

         (A) a registration statement under the Securities Act, on an
appropriate form, with respect to the Rights and the Common Shares of such
issuer purchasable upon exercise of the Rights shall be effective; and

         (B) the Company and each such issuer shall have:

         (1)      executed and delivered to the Rights Agent a supplemental
agreement providing for the assumption by such issuer of the obligations set
forth in this Section 11(d) (including the obligation of such issuer to issue
Common Shares upon the exercise of Rights in accordance with the terms set forth
in Sections 11(d)(i) and 11(d)(iii)) and further providing that such issuer, at
its own expense, will use its best efforts to:

                                      -17-
<PAGE>   21

                  (x)      cause a registration statement under the Securities
         Act, on an appropriate form, with respect to the Rights and the Common
         Shares of such issuer purchasable upon exercise of the Rights to remain
         effective (with a prospectus at all times meeting the requirements of
         the Securities Act) until the Expiration Date;

                  (y)      qualify or register the Rights and the Common Shares
         of such issuer purchasable upon exercise of the Rights under the blue
         sky or securities laws of such jurisdictions as may be necessary or
         appropriate; and

                  (z)      list the Rights and the Common Shares of such issuer
         purchasable upon exercise of the Rights on each national securities
         exchange on which the Common Stock was listed prior to the consummation
         of the Business Combination or, if the Common Stock was not listed on a
         national securities exchange prior to the consummation of the Business
         Combination, on a national securities exchange;

         (2)      furnished to the Rights Agent a written opinion of independent
counsel stating that such supplemental agreement is a valid, binding and
enforceable agreement of such issuer; and

         (3)      filed with the Rights Agent a certificate of a nationally
recognized firm of independent accountants setting forth the number of Common
Shares of such issuer that may be purchased upon the exercise of each Right
after the consummation of such Business Combination.

         (iii)    After consummation of any Business Combination and subject to
the provisions of Section 11(d)(ii), (A) each issuer of Common Shares for which
Rights may be exercised as set forth in this Section 11(d) shall be liable for,
and shall assume, by virtue of such Business Combination, all the obligations
and duties of the Company pursuant to this Rights Agreement, (B) the term
"Company" shall thereafter be deemed to refer to such issuer, (C) each such
issuer shall take such steps in connection with such consummation as may be
necessary to ensure that the provisions of this Rights Agreement (including the
provisions of Sections 11(a) and 11(b)) shall thereafter apply, as nearly as
reasonably may be, in relation to its Common Shares thereafter deliverable upon
the exercise of the Rights, and (D) the number of Common Shares of each such
issuer thereafter receivable upon exercise of any Right shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions of Sections 11(a) and 12(a), and the provisions of
Sections 7, 9 and 10 with respect to the Preferred Shares shall apply, as nearly
as reasonably may be, on like terms to any such Common Shares.

                                      -18-
<PAGE>   22
SECTION 12.           CERTAIN ADJUSTMENTS

         (a)      To preserve the actual or potential economic value of the
Rights, if at any time after the date of this Rights Agreement there shall be
any change in the Common Stock or the Preferred Shares, whether by reason of
stock dividends, stock splits, recapitalizations, mergers, consolidations,
combinations or exchanges of securities, split-ups, split-offs, spin-offs,
liquidations, other similar changes in capitalization, any distribution or
issuance of cash, assets, evidences of indebtedness or subscription rights,
options or warrants to holders of Common Stock or Preferred Shares, as the case
may be (other than the Rights or regular quarterly cash dividends), or
otherwise, then, in each such event the Company's Board of Directors shall make
such appropriate adjustments in the number of Preferred Shares (or the number
and kind of other securities) issuable upon exercise of each Right, the Purchase
Price and Redemption Price in effect at such time and the number of Rights
outstanding at such time (including the number of Rights or fractional Rights
associated with each share of Common Stock) such that following such adjustment
such event shall not have had the effect of reducing or limiting the benefits
the holders of the Rights would have had absent such event.

         (b)      If, as a result of an adjustment made pursuant to Section
12(a), the holder of any Right thereafter exercised shall become entitled to
receive any securities other than Preferred Shares, then the number of such
securities so receivable upon exercise of any Right thereafter shall be subject
to adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions of Sections 11(a) and 12(a), and the provisions of
Sections 7, 9 and 10 with respect to the Preferred Shares shall apply, as nearly
as reasonably may be possible, on like terms to any such other securities.

         (c)      All Rights originally issued by the Company subsequent to any
adjustment made to the amount of Preferred Shares or other securities relating
to a Right shall evidence the right to purchase, for the Purchase Price, the
adjusted number and kind of securities purchasable from time to time under this
Rights Agreement upon exercise of the Rights, all subject to further adjustment
as provided in this Rights Agreement.

         (d)      Irrespective of any adjustment or change in the Purchase Price
or the number of Preferred Shares or number or kind of other securities issuable
upon the exercise of the Rights, the Right Certificates theretofore and
thereafter issued may continue to express the terms that were expressed in the
initial Right Certificates issued under this Rights Agreement.

         (e)      In any case in which action taken pursuant to Section 12(a)
requires that an adjustment be made effective as of a record date for a
specified event, the Company may elect to defer, until the occurrence of such
event, issuing to the holder of any Right exercised after such record date the
Preferred Shares and/or other securities, if any, issuable upon such exercise
over and above the Preferred Shares and/or other securities, if any, issuable
before giving effect to such adjustment; provided, however, that the Company
shall deliver to such holder a due bill or other appropriate instrument
evidencing such holder's right to receive such additional securities upon the
occurrence of the event requiring such adjustment.

                                      -19-
<PAGE>   23
SECTION 13.           CERTIFICATE OF ADJUSTMENT

         Whenever an adjustment is made as provided in Section 11 or 12, the
Company shall (a) promptly prepare a certificate setting forth such adjustment
and a brief statement of the facts accounting for such adjustment, (b) promptly
file with the Rights Agent and with each transfer agent for the Preferred Shares
a copy of such certificate, and (c) mail a brief summary thereof to each holder
of a Right Certificate (or, prior to the Distribution Date, of Common Stock) in
accordance with Section 25.

SECTION 14.           ADDITIONAL COVENANTS

         (a) Notwithstanding any other provision of this Rights Agreement, no
adjustment to the number of Preferred Shares (or fraction of a share) or other
securities for which a Right is exercisable or the number of Rights outstanding
or associated with each Common Share or any similar or other adjustment shall be
made or be effective if such adjustment would have the effect of reducing or
limiting the benefits the holders of the Rights would have had absent such
adjustment, including, without limitation, the benefits under Sections 11 and
12, unless the terms of this Rights Agreement are amended so as to preserve such
benefits.

         (b) The Company covenants and agrees that, after the Distribution Date,
except as permitted by Section 26, it will not take (or permit any Subsidiary of
the Company to take) any action if at the time such action is taken it is
reasonably foreseeable that such action will reduce or otherwise limit the
benefits the holders of the Rights would have had absent such action, including,
without limitation, the benefits under Sections 11 and 12. Any action taken by
the Company during any period after any Person becomes an Acquiring Person but
prior to the Distribution Date shall be null and void unless such action could
be taken under this Section 14(b) from and after the Distribution Date.

SECTION 15.           FRACTIONAL RIGHTS AND FRACTIONAL SHARES

         (a) The Company may, but shall not be required to, issue fractional
Rights or distribute Right Certificates that evidence fractional Rights. In lieu
of such fractional Rights, the Company may pay to the registered holders of the
Right Certificates with regard to which such fractional Rights would otherwise
be issuable an amount in cash equal to the same fraction of the current market
value of a whole Right. For purposes of this Section 15(a), the current market
value of a whole Right shall be the closing price of the Rights (as determined
pursuant to the second and third sentences of the definition of Market Value
contained in Section 1) for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable.

         (b) The Company may, but shall not be required to, issue fractional
Preferred Shares upon exercise of the Rights or distribute certificates that
evidence fractional Preferred Shares. In lieu of fractional Preferred Shares,
the Company may elect to (i) utilize a depository arrangement as provided by the
terms of the Preferred Shares or (ii) in the case of a fractional Preferred
Share (other than one one-hundredth (1/100th) of a Preferred Share or any
integral multiple thereof), pay to the registered holders of Right Certificates
at the time 

                                      -20-
<PAGE>   24
such Rights are exercised as provided in this Rights Agreement an amount in cash
equal to the same fraction of the current market value of one Preferred Share,
if any are outstanding and publicly traded (or the Formula Number times the
current market value of one share of Common Stock if the Preferred Shares are
not outstanding and publicly traded). For purposes of this Section 15(b), the
current market value of a Preferred Share (or share of Common Stock) shall be
the closing price of a Preferred Share (or share of Common Stock) (as determined
pursuant to the second and third sentences of the definition of Market Value
contained in Section 1) for the Trading Day immediately prior to the date of
such exercise. If, as a result of an adjustment made pursuant to Section 12(a),
the holder of any Right thereafter exercised shall become entitled to receive
any securities other than Preferred Shares, the provisions of this Section 15(b)
shall apply, as nearly as reasonably may be, on like terms to such other
securities.

         (c) The Company may, but shall not be required to, issue fractional
Common Shares upon exchange of Rights pursuant to Section 11(b), or to
distribute certificates that evidence fractional Common Shares. In lieu of such
fractional Common Shares, the Company may pay to the registered holders of Right
Certificates with regard to which such fractional Common Shares would otherwise
be issuable an amount in cash equal to the same fraction of the current Market
Value of one Common Share as of the date on which a Person became an Acquiring
Person.

         (d) Each holder of Rights by accepting the Rights expressly waives his
or her right to receive any fractional Rights or any fractional shares upon
exercise of a Right, except as provided in this Section 15.

SECTION 16.           RIGHTS OF ACTION

         (a) All rights of action in respect of this Rights Agreement are vested
in the respective registered holders of the Right Certificates (and, prior to
the Distribution Date, the registered holders of the Common Stock), and any
registered holder of any Right Certificate (or, prior to the Distribution Date,
of the Common Stock), without the consent of the Rights Agent or of the holder
of any other Right Certificate (or, prior to the Distribution Date, of the
Common Stock), may, in his or her own behalf and for his or her own benefit,
enforce, and may institute and maintain any suit, action or proceeding against
the Company to enforce, or otherwise act in respect of, his or her right to
exercise the Rights evidenced by such Right Certificate in the manner provided
in such Right Certificate and in the Rights Agreement. Without limiting the
foregoing or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Rights Agreement and shall be entitled to specific
performance of the obligations of any Person under, and injunctive relief
against actual or threatened violations of the obligations of any Person subject
to, this Rights Agreement.

         (b) Any holder of Rights who prevails in an action to enforce the
provisions of this Rights Agreement shall be entitled to recover the reasonable
costs and expenses, including attorneys' fees, incurred in such action.

<PAGE>   25
SECTION 17.           AGREEMENT OF RIGHT HOLDERS

         Every holder of a Right, by accepting the same, consents and agrees
with the Company and the Rights Agent and with every other holder of a Right
that:

         (a)      prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Stock;

         (b)      after the Distribution Date, the Right Certificates will be
transferable, subject to Section 7(e), only on the registry books of the Rights
Agent if surrendered at the principal office of the Rights Agent, duly endorsed
or accompanied by a proper instrument of transfer; and

         (c)      the Company and the Rights Agent may deem and treat the Person
in which name a Right Certificate (or, prior to the Distribution Date, the
associated Common Stock certificate) is registered as the absolute owner thereof
and of the Rights evidenced thereby (notwithstanding any notations of ownership
or writing on the Right Certificates or the associated Common Stock certificate
made by anyone other than the Company or the Rights Agent) for all purposes
whatsoever, and neither the Company nor the Rights Agent shall be affected by
any notice to the contrary.

SECTION 18.           RIGHT CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER

         No holder, as such, of any Right Certificate shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company that may at any time be
issuable on the exercise of the Rights represented thereby, nor shall anything
contained in this Rights Agreement or in any Right Certificate be construed to
confer upon the holder of any Right Certificate, as such, any of the rights of a
shareholder of the Company, including, without limitation, any right to vote for
the election of directors or on any matter submitted to shareholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting shareholders, or to
receive dividends or other distributions or subscription rights, or otherwise,
until the Right or Rights evidenced by such Right Certificate shall have been
exercised in accordance with the provisions of this Rights Agreement.

SECTION 19.           CONCERNING THE RIGHTS AGENT

         (a)      The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it under this Rights Agreement and,
from time to time, on demand of the Rights Agent, its reasonable expenses and
counsel fees and other disbursements incurred in administering and executing
this Rights Agreement and exercising and performing its duties under this Rights
Agreement.

         (b)      The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this Rights Agreement in reliance on any
Right Certificate or certificate for the Common Stock or 

                                      -22-
<PAGE>   26
for other securities of the Company, instrument of assignment or transfer, power
of attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged by the
proper Person or Persons.

SECTION 20.           MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT

         (a)      Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the stock transfer or corporate trust business of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Rights Agreement without the execution or filing of any paper or any further act
on the part of any of the parties to this Rights Agreement; provided, however,
that such corporation would be eligible for appointment as a successor Rights
Agent under the provisions of Section 22. In case at the time such successor
Rights Agent shall succeed to the agency created by this Rights Agreement any of
the Right Certificates shall have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Right Certificates so countersigned; and, in case at that
time any of the Right Certificates shall not have been countersigned, any
successor Rights Agent may countersign such Right Certificates either in the
name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and, in all such cases, such Right Certificates shall have the full force
provided in the Right Certificates and in this Rights Agreement.

         (b)      In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; and, in
case at that time any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such Right Certificates either
in its prior name or in its changed name; and, in all such cases, such Right
Certificates shall have the full force provided in the Right Certificates and in
this Rights Agreement.

SECTION 21.           DUTIES OF RIGHTS AGENT

         The Rights Agent undertakes the duties and obligations imposed by this
Rights Agreement upon the following terms and conditions, by all of which the
Company and the holders of Right Certificates (or, prior to the Distribution
Date, of the Common Stock), by their acceptance thereof, shall be bound:

         (a)      The Rights Agent may consult with legal counsel (who may be
legal counsel for the Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken, suffered or omitted by it in good faith and in accordance with such
opinion.

                                      -23-
<PAGE>   27
         (b)      Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person) be
proved or established by the Company prior to taking, refraining from taking or
suffering any action under this Rights Agreement, such fact or matter (unless
other evidence in respect thereof be specifically prescribed in this Rights
Agreement) may be deemed to be conclusively proved and established by a
certificate signed by any one of the Chairman of the Board, the Chief Executive
Officer, the President, the Chief Operating Officer, the Chief Financial
Officer, a Vice President (whether preceded by any additional title), the
Treasurer or the Secretary of the Company and delivered to the Rights Agent, and
such certificate shall be full authorization to the Rights Agent for any action
taken or suffered in good faith by it under the provisions of this Rights
Agreement in reliance upon such certificate.

         (c)      The Company shall indemnify the Rights Agent for, and hold it
harmless against, any loss, liability or expense incurred without gross
negligence, bad faith or intentional misconduct on its part arising out of or in
connection with its duties under this Rights Agreement, including the costs and
expenses of defending itself against any claim or liability in connection with
its exercise or performance of any of its duties under this Rights Agreement. In
no case will the Rights Agent be liable for special, indirect, incidental or
consequential loss or damage of any kind whatsoever, even if the Rights Agent
has been advised of the possibility of such loss or damage.

         (d)      The Rights Agent shall not be liable for or by reason of any
of the statements of fact or recitals contained in this Rights Agreement or in
the Right Certificates (except as to its countersignature thereof) or be
required to verify the same, but all such statements and recitals are and shall
be deemed to have been made by the Company only.

         (e)      The Rights Agent shall not be under any responsibility in
respect of the validity of this Rights Agreement or the execution and delivery
hereof (except the due execution of this Rights Agreement by the Rights Agent)
or in respect of the validity or execution of any Right Certificate (except its
countersignature thereof); it shall not be responsible for any breach by the
Company of any covenant or condition contained in this Rights Agreement or in
any Right Certificate; it shall not be responsible for any adjustment required
under the provisions of Section 11 or 12 or responsible for the manner, method
or amount of any such adjustment or the ascertaining of the existence of facts
that would require any such adjustment (except with respect to the exercise of
Rights evidenced by Right Certificates after actual notice of any such
adjustment); and it shall not by any act under this Rights Agreement be deemed
to make any representation or warranty as to the authorization or reservation of
any Preferred Shares or Common Stock to be issued pursuant to this Rights
Agreement or any Right Certificate or as to whether any Preferred Shares or
Common Stock will, when so issued, be validly authorized and issued, fully paid
and nonassessable.

         (f)      The Company agrees that it will perform, execute, acknowledge
and deliver or cause to be performed, executed, acknowledged and delivered all
such further and other acts, instruments and assurances as may reasonably be
required by the Rights Agent for the carrying out or performing by the Rights
Agent of the provisions of this Rights Agreement.

                                      -24-
<PAGE>   28
         (g)      The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties under this Rights
Agreement from any one of the Chairman of the Board, the Chief Executive
Officer, the President, the Chief Operating Officer, the Chief Financial
Officer, a Vice President (whether preceded by any additional title), the
Secretary or the Treasurer of the Company in connection with its duties, and it
shall not be liable for any action taken or suffered to be taken by it in good
faith in accordance with the instructions of any such officer.

         (h)      The Rights Agent and any shareholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not the Rights
Agent under this Rights Agreement. Nothing in this Rights Agreement shall
preclude the Rights Agent from acting in any other capacity for the Company or
for any other legal entity.

         (i)      The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty under this Rights Agreement
either itself or by or through its attorneys or agents, and the Rights Agent
shall not be answerable or accountable for any act, default, neglect or
misconduct of any such attorneys or agents or for any loss to the Company
resulting from any such act, default, neglect or misconduct provided reasonable
care was exercised in the selection and continued employment thereof.

SECTION 22.           CHANGE OF RIGHTS AGENT

         The Rights Agent or any successor Rights Agent may resign and be
discharged from its duties under this Rights Agreement upon 30 days' notice in
writing mailed to the Company and to each transfer agent of the Common Stock and
the Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates (or, prior to the Distribution Date, of the Common Stock) by
first-class mail. The Company may remove the Rights Agent or any successor
Rights Agent upon 30 days' notice in writing mailed to the Rights Agent or
successor Rights Agent, as the case may be, and to each transfer agent of the
Common Stock and the Preferred Shares by registered or certified mail, and to
the holders of the Right Certificates (or, prior to the Distribution Date, of
the Common Stock) by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(or, prior to the Distribution Date, of the Common Stock) (who shall, with such
notice, submit his or her Right Certificate or, prior to the Distribution Date,
the certificate representing his or her Common Stock, for inspection by the
Company), then the registered holder of any Right Certificate (or, prior to the
Distribution Date, of the Common Stock) may apply to any court of competent
jurisdiction for the appointment of a new Rights Agent. Any successor Rights
Agent, whether appointed by the Company or by such a court, shall be a
corporation in good standing organized and doing business under the laws of the
United States or of the state of Washington (or of any other 

                                      -25-
<PAGE>   29
state of the United States so long as such corporation is authorized to conduct
a stock transfer or corporate trust business in the state of Washington) and
having a principal office in the state of Washington, which is authorized under
such laws to exercise stock transfer or corporate trust powers and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50,000,000. After appointment, the successor Rights Agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named as Rights Agent without further act or deed; provided, however,
that the predecessor Rights Agent shall deliver and transfer to the successor
Rights Agent any property at the time held by it under this Rights Agreement,
and execute and deliver any further assurance, conveyance, act or deed necessary
for the purpose. Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock and the Preferred Shares, and mail a
notice thereof in writing to the registered holders of the Right Certificates
(or, prior to the Distribution Date, of the Common Stock). Failure to give any
notice provided for in this Section 22, however, or any defect therein shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

SECTION 23.           ISSUANCE OF ADDITIONAL RIGHTS AND RIGHT CERTIFICATES

         Notwithstanding any of the provisions of this Rights Agreement or of
the Rights to the contrary, the Company may, at its option, issue new Right
Certificates evidencing Rights in such form as may be approved by its Board of
Directors to reflect any adjustment or change made in accordance with the
provisions of this Rights Agreement. In addition, in connection with the
issuance or sale of Common Stock following the Distribution Date and prior to
the earlier of the Redemption Date and the Expiration Date, the Company (a)
shall issue, with respect to Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, or upon the
exercise, conversion or exchange of securities, notes or debentures issued by
the Company, and (b) may issue, in any other case, if deemed necessary or
appropriate by the Company's Board of Directors, Right Certificates representing
the appropriate number of Rights in connection with such issuance or sale;
provided, however, that (i) no such Right Certificate shall be issued if, and to
the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the
Company or the Person to whom such Right Certificate would be issued and (ii) no
such Right Certificate shall be issued if, and to the extent that, appropriate
adjustment shall otherwise have been made in lieu of the issuance thereof.

SECTION 24.           REDEMPTION AND TERMINATION

         (a)      The Company's Board of Directors may, at its option, at any
time prior to such time as any Person becomes an Acquiring Person, order the
redemption of all, but not fewer than all, the then outstanding Rights at the
Redemption Price (the date of such redemption being the "Redemption Date"). The
redemption of the Rights by the Board of Directors may 

                                      -26-
<PAGE>   30
be made effective at such time, on such basis and with such conditions as the
Board of Directors in its sole discretion may establish.

         (b)      Immediately upon the action of the Company's Board of
Directors ordering the redemption of the Rights, and without any further action
and without any notice, the right to exercise the Rights will terminate and the
only right thereafter of the holders of Rights shall be to receive the
Redemption Price. Within 10 Business Days after the action of the Company's
Board of Directors ordering the redemption of the Rights, the Company shall give
notice of such redemption to the holders of the then outstanding Rights by
mailing such notice to all such holders at their last addresses as they appear
upon the registry books of the Rights Agent or, prior to the Distribution Date,
on the registry books of the transfer agent for the Common Stock. Each such
notice of redemption will state the method by which payment of the Redemption
Price will be made. The notice, if mailed in the manner provided in this Rights
Agreement, shall be conclusively presumed to have been duly given, whether or
not the holder of Rights receives such notice. In any case, failure to give such
notice by mail, or any defect in the notice, to any particular holder of Rights
shall not affect the sufficiency of the notice to other holders of Rights.

SECTION 25.           NOTICES

         Notices or demands authorized by this Rights Agreement to be given or
made by the Rights Agent or by the holder of a Right Certificate (or, prior to
the Distribution Date, of Common Stock) to or on the Company shall be

Company so directs, supplement or amend any provision of this Rights Agreement
(including, without limitation, the date on which the Distribution Date shall
occur, the time during which the Rights may be redeemed pursuant to Section 24
or any provision of the Designation of Rights and Preferences) without the

Company so directs, amend this Rights Agreement without the approval of any
holder of Right Certificates to (a) cure any ambiguity or correct or supplement
any provision contained in this Rights Agreement that may be defective or

other provisions in regard to matters or questions arising under this Rights
Agreement that the Company may deem necessary or desirable and that shall not
adversely affect the interests of the holders of Right Certificates (other than
an Acquiring Person or an Affiliate or Associate of an Acquiring Person). Any
supplement or amendment adopted during any period after any Person has become an
Acquiring Person but prior to the Distribution Date shall be null and void
unless such supplement or amendment could have been adopted under the prior
sentence from and after the Distribution Date. Any supplement or amendment to
this Rights Agreement duly approved by the Company shall become effective

Rights Agent.

Common Stock).

                    ADVANCED DIGITAL INFORMATION CORPORATION
                     DESIGNATION OF RIGHTS AND PREFERENCES
                            OF SERIES A PARTICIPATING
                           CUMULATIVE PREFERRED STOCK


         The Board of Directors of Advanced Digital Information Corporation (the
"Corporation") hereby establishes a series of the Corporation's Preferred Stock
designated as Series A Participating Cumulative Preferred Stock. The rights,
preferences, restrictions and other matters relating to the Series A
Participating Cumulative Preferred Stock are set forth below:

SECTION 1.            DESIGNATION AND NUMBER OF SHARES

         The shares of such series shall be designated the "Series A
Participating Cumulative Preferred Stock" (the "Series A Preferred Stock"), no
par value. The number of shares initially constituting the Series A Preferred
Stock shall be 100,000 provided, however, that if more than a total of 100,000
shares of Series A Preferred Stock shall be issuable upon the exercise of Rights
(the "Rights") issued pursuant to the Rights Agreement dated as of August 12,
1996 between the Corporation and ChaseMellon Shareholder Services, L.L.C., as
Rights Agent (the "Rights Agreement"), the Corporation's Board of Directors,
pursuant to Section 23B.06.020 of the Washington Business Corporation Act, shall
direct by resolution that Articles of Amendment be properly executed and filed
in accordance with the provisions thereof, providing for the total number of
shares of Series A Preferred Stock authorized to be issued to be increased (to
the extent that the Amended and Restated Articles of Incorporation then permit)
to the largest number of whole shares (rounded up to the nearest whole number)
issuable upon exercise of such Rights.

SECTION 2.            DIVIDENDS OR DISTRIBUTIONS

         (a)      Subject to the prior and superior rights of the holders of
shares of any other series of Preferred Stock or other class of capital stock of
the Corporation ranking prior and superior to the shares of Series A Preferred
Stock with respect to dividends, the holders of shares of Series A Preferred
Stock shall be entitled to receive, when, as, and if declared by the Board of
Directors, out of the assets of the Corporation legally available therefor,
quarterly dividends payable in cash on the last day of each fiscal quarter in
each year, or such other dates as the Corporation's Board of Directors shall
approve (each such date being referred to in this Designation of Rights and
Preferences as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or a
fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (i) $.01 and (ii) the Formula
Number (as hereinafter defined) then in effect times the cash dividends then to
be paid on each share of Common Stock. In addition, if the Corporation shall pay
any dividend or make any distribution on the

                                      A-1
<PAGE>   35
Common Stock payable in assets, securities or other forms of noncash
consideration (other than dividends or distributions solely in shares of Common
Stock), then, in each such case, the Corporation shall simultaneously pay or
make on each outstanding whole share of Series A Preferred Stock a dividend or
distribution in like kind equal to the Formula Number then in effect times such
dividend or distribution on each share of Common Stock. As used in this
Designation of Rights and Preferences and in the Rights Agreement, the "Formula
Number" shall be 100; provided, however, that if at any time after the date of
the closing of the Spinoff (as defined in the Rights Agreement), the Corporation
shall (i) declare or pay any dividend on the Common Stock payable in shares of
Common Stock or make any distribution on the Common Stock in shares of Common
Stock, (ii) subdivide (by a stock split or otherwise) the outstanding shares of
Common Stock into a larger number of shares of Common Stock, or (iii) combine
(by a reverse stock split or otherwise) the outstanding shares of Common Stock
into a smaller number of shares of Common Stock, then in each such event the
Formula Number shall be adjusted to a number determined by multiplying the
Formula Number in effect immediately prior to such event by a fraction, the
numerator of which is the number of shares of Common Stock that are outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that are outstanding immediately prior to such event (and
rounding the result to the nearest whole number); and provided further, that if
at any time after the date of the closing of the Spinoff the Corporation shall
issue any shares of its capital stock in a merger, reclassification or change of
the outstanding shares of Common Stock, then in each such event the Formula
Number shall be appropriately adjusted to reflect such merger, reclassification
or change so that each share of Preferred Stock continues to be the economic
equivalent of a Formula Number of shares of Common Stock prior to such merger,
reclassification or change.

         (b)      The Corporation shall declare a dividend or distribution on
the Series A Preferred Stock as provided in Section 2(a) immediately prior to or
at the same time it declares a dividend or distribution on the Common Stock
(other than a dividend or distribution solely in shares of Common Stock);
provided, however, that in the event no dividend or distribution (other than a
dividend or distribution in shares of Common Stock) shall have been declared on
the Common Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $.01 per
share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date. The Corporation's Board of Directors
may fix a record date for the determination of holders of shares of Series A
Preferred Stock entitled to receive a dividend or distribution declared thereon,
which record date shall be the same as the record date for any corresponding
dividend or distribution on the Common Stock and which shall not be more than 60
days prior to the date fixed for payment thereof.

         (c)      Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from and after the Quarterly
Dividend Payment Date next preceding the date of original issue of such shares
of Series A Preferred Stock; provided, however, that dividends on such shares
that are originally issued after the record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a quarterly
dividend and on or prior to the next succeeding Quarterly Dividend Payment Date
shall begin to accrue and be cumulative from and after such Quarterly Dividend
Payment Date. Notwithstanding the 

                                      A-2
<PAGE>   36
foregoing, dividends on shares of Series A Preferred Stock that are originally
issued prior to the record date for the first Quarterly Dividend Payment shall
be calculated as if cumulative from and after the last day of the fiscal quarter
(or such other Quarterly Dividend Payment Date as the Corporation's Board of
Directors shall approve) next preceding the date of original issuance of such
shares. Accrued but unpaid dividends shall not bear interest. Dividends paid on
the shares of Series A Preferred Stock 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.

         (d)      So long as any shares of Series A Preferred Stock are
outstanding, no dividends or other distributions shall be declared, paid or
distributed, or set aside for payment or distribution, on the Common Stock
unless, in each case, the dividend required by this Section 2 to be declared on
the Series A Preferred Stock shall have been declared.

         (e)      The holders of shares of Series A Preferred Stock shall not be
entitled to receive any dividends or other distributions except as provided in
this Designation of Rights and Preferences.

SECTION 3.            VOTING RIGHTS

         The holders of shares of Series A Preferred Stock shall have the
following voting rights:

         (a)      Each holder of Series A Preferred Stock shall be entitled to a
number of votes equal to the Formula Number then in effect for each share of
Series A Preferred Stock held of record on each matter on which holders of the
Common Stock or shareholders generally are entitled to vote, multiplied by the
maximum number of votes per share that any holders of the Common Stock or
shareholders generally then have with respect to such matter (assuming any
holding period or other requirement to vote a greater number of shares is
satisfied).

         (b)      Except as otherwise provided in this Designation of Rights and
Preferences or by applicable law, the holders of shares of Series A Preferred
Stock and the holders of shares of Common Stock and any other capital stock of
the Corporation having general voting rights shall vote together as one class
for the election of directors of the Corporation and on all other matters
submitted to a vote of shareholders of the Corporation.

         (c)      Except as provided in this Designation of Rights and
Preferences or by applicable law, holders of Series A Preferred Stock shall have
no special voting rights and their consent shall not be required (except to the
extent they are entitled to vote with holders of Common Stock as set forth in
this Designation of Rights and Preferences) for authorizing or taking any
corporate action.

SECTION 4.            CERTAIN RESTRICTIONS

         (a)      Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A 

                                       A-3
<PAGE>   37
Preferred Stock outstanding shall have been paid in full, the Corporation shall
not:

                  (i) declare or pay dividends on, make any other distributions
         on, or redeem or purchase or otherwise acquire for consideration any
         shares of stock ranking junior (either as to dividends or upon
         liquidation, dissolution or winding up) to the Series A Preferred
         Stock;

                  (ii) declare or pay dividends on or make any other
         distributions on any shares of stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Preferred Stock, except dividends paid ratably on the Series A
         Preferred Stock and all such parity stock on which dividends are
         payable or in arrears in proportion to the total amounts to which the
         holders of all such shares are then entitled;

                  (iii) redeem or purchase or otherwise acquire for
         consideration shares of any stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Preferred Stock; provided, however, that the Corporation may
         at any time redeem, purchase or otherwise acquire shares of any such
         junior stock in exchange for shares of any stock of the Corporation
         ranking junior (either as to dividends or upon dissolution, liquidation
         or winding up) to the Series A Preferred Stock; or

                  (iv) redeem or purchase or otherwise acquire for consideration
         any shares of Series A Preferred Stock, or any shares of stock ranking
         on a parity with the Series A Preferred Stock, except in accordance
         with a purchase offer made in writing or by publication (as determined
         by the Corporation's Board of Directors) to all holders of such shares
         upon such terms as the Corporation's Board of Directors, after
         consideration of the respective annual dividend rates and other
         relative rights and preferences of the respective series and classes,
         shall determine in good faith will result in fair and equitable
         treatment among the respective series or classes.

         (b)      The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

SECTION 5.            LIQUIDATION RIGHTS

         Upon the liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary, no distribution shall be made to (a) the
holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received an amount equal to the greater of (i) $.01 per share and (ii) the
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, plus an aggregate amount per share equal to the
Formula Number then in effect times the aggregate amount to be distributed per
share to holders of Common Stock or (b) the 

                                      A-4
<PAGE>   38
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all other
such parity stock in proportion to the total amounts to which the holders of all
such shares are entitled upon such liquidation, dissolution or winding up.

SECTION 6.            CONSOLIDATION, MERGER, ETC.

         In case the Corporation shall enter into 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 then outstanding shares of Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share equal to the Formula Number then in effect 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
exchanged or changed. In the event both this Section 6 and Section 2 appear to
apply to a transaction, this Section 6 will control.

SECTION 7.            NO REDEMPTION; NO SINKING FUND

         (a) The shares of Series A Preferred Stock shall not be subject to
redemption by the Corporation or at the option of any holder of Series A
Preferred Stock; provided, however, that the Corporation may purchase or
otherwise acquire outstanding shares of Series A Preferred Stock in the open
market or by offer to any holder or holders of shares of Series A Preferred
Stock.

         (b) The shares of Series A Preferred Stock shall not be subject to or
entitled to the operation of a retirement or sinking fund.

SECTION 8.            RANKING

         The Series A Preferred Stock shall rank junior to all other series of
Preferred Stock of the Corporation, unless the Corporation's Board of Directors
shall specifically determine otherwise in fixing the powers, preferences and
relative, participating, optional and other special rights of the shares of such
series and the qualifications, limitations and restrictions thereof.

SECTION 9.            FRACTIONAL SHARES

         The Series A Preferred Stock shall be issuable upon exercise of the
Rights issued pursuant to the Rights Agreement in whole shares or in any
fractional share that is one one-hundredth (1/100th) of a share or any integral
multiple of such fraction, and shall entitle the holder, in proportion to such
holder's fractional shares, to receive dividends, exercise voting rights,
participate in distributions and have the benefit of all other rights of holders
of Series A Preferred Stock. In lieu of fractional shares, the Corporation,
prior to the first issuance of a share or a fractional share of Series A
Preferred Stock, may elect to (a) make a cash payment as provided in the Rights
Agreement for a fractional share other than one one-hundredth 

                                      A-5
<PAGE>   39
(1/100th) of a share or any integral multiple thereof or (b) issue depository
receipts evidencing such authorized fractional share of Series A Preferred Stock
pursuant to an appropriate agreement between the Corporation and a depository
selected by the Corporation; provided, however, that such agreement shall
provide that the holders of such depository receipts shall have all the rights,
privileges and preferences to which they are entitled as holders of the Series A
Preferred Stock.

SECTION 10.           REACQUIRED SHARES

         Any shares of Series A Preferred Stock 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 shares of Preferred Stock, without
designation as to series until such shares are once more designated as part of a
particular series by the Corporation's Board of Directors pursuant to the
provisions of Article 4 of the Amended and Restated Articles of Incorporation.

SECTION 11.           AMENDMENT

         None of the powers, preferences and relative, participating, optional
and other special rights of the Series A Preferred Stock as provided in this
Designation of Rights and Preferences or in the Amended and Restated Articles of
Incorporation shall be amended in any manner that would alter or change the
powers, preferences, rights or privileges of the holders of Series A Preferred
Stock so as to affect them adversely without the affirmative vote of the holders
of at least 66-2/3% of the outstanding shares of Series A Preferred Stock,
voting as a separate class.

         RIGHTS ARE NULL AND VOID AND NONTRANSFERABLE.



                                RIGHT CERTIFICATE

                    ADVANCED DIGITAL INFORMATION CORPORATION

         This certifies that         , or registered assigns, is the registered
owner of the number of Rights set forth above, each of which entitles the owner
thereof, subject to the terms, provisions and conditions of the Rights Agreement
dated as of August 12, 1996 (the "Rights Agreement"), between Advanced Digital
Information Corporation, a Washington corporation (the "Company"), and
ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent"),
unless the Rights evidenced hereby shall have been previously redeemed by the
Company, to purchase from the Company at any time after the Distribution Date
(as defined in the Rights Agreement) and prior to 5 p.m., New York City time, on
[Record Date + 10 years], 2006, at the principal office of the Rights Agent, or
its successors as Rights Agent (in Seattle, Washington), one one-hundredth
(1/100th) of a fully paid, nonassessable share of Series A Participating
Cumulative Preferred Stock, no par value, of the Company (the "Preferred
Shares"), at a purchase price per one one-hundredth (1/100th) of a share equal
to $50 (the "Purchase Price"), upon presentation and surrender of this Right
Certificate with the Form of Election to Purchase duly executed.

                                      B-1
<PAGE>   41
         The Purchase Price and the number and kind of shares that may be
purchased upon exercise of each Right evidenced by this Right Certificate, as
set forth above, are the Purchase Price and the number and kind of shares that
may be so purchased as of [Record Date]. As provided in the Rights Agreement,
the Purchase Price and the number and kind of shares that may be purchased upon
the exercise of each Right evidenced by this Right Certificate are subject to
modification and adjustment upon the happening of certain events.

         If the Rights evidenced by this Right Certificate are at any time
beneficially owned by an Acquiring Person or an Affiliate or Associate of an
Acquiring Person (as such terms are defined in the Rights Agreement), such
Rights shall be null and void and nontransferable and the holder of any such
Right (including any purported transferee or subsequent holder) shall not have
any right to exercise or transfer any such Right.

         This Right Certificate is subject to all the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated in this Right Certificate by reference and made a part
hereof and to which reference to the Rights Agreement is hereby made for a full
description of the rights, limitations of rights, obligations, duties and
immunities under this Right Certificate of the Rights Agent, the Company and the
holders of the Right Certificates. Copies of the Rights Agreement are on file at
the above-mentioned office of the Rights Agent and are also available from the

Rights Agent, may be exchanged for another Right Certificate or Right
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number and kind of shares as the Rights evidenced by

holder shall be entitled to receive upon surrender hereof another Right
Certificate or Right Certificates for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Right Certificate may be (i) redeemed by the Company at its option at a
redemption price (in cash or shares of Common Stock or other securities of the
Company deemed by the Company's Board of Directors to be at least equivalent in
value) of $.01 per Right (which amount shall be subject to adjustment as
provided in the Rights Agreement) or (ii) exchanged in whole or in part for
shares of Common Stock or other securities of the Company.

         The Company may, but shall not be required to, issue fractions of
Preferred Shares or distribute certificates that evidence fractions of Preferred
Shares upon the exercise of any Right or Rights evidenced hereby. In lieu of
issuing fractional shares, the Company may elect to make a cash payment as
provided in the Rights Agreement for fractions of a share other than one
one-hundredth (1/100th) of a share or any integral multiple thereof or to issue
certificates or utilize a depository arrangement as provided in the terms of the
Rights Agreement and the Preferred Shares.

         No holder of this Right Certificate shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company that may at any time be
issuable on the exercise of the Right or Rights evidenced by this Right
Certificate, nor shall anything contained in the Rights Agreement or in this

corporate action, or to receive notice of meetings or other actions affecting

<PAGE>   9
provided herein, Interpoint shall be entitled to the benefit of all refunds
(whether actual or constructive) of federal, state, local or foreign Income
Taxes, and all interest attributable thereto, resulting from any Final
Determination which adjusts any Tax Item of any Interpoint Company for any tax
period or portion thereof.

         5.02    DETERMINATION OF INDEMNIFICATION AMOUNTS

         If any Final Determination results in an adjustment to any Tax Item of
any ADIC Company or Interpoint Company for any Tax period or portion thereof
ending on or before the Disaffiliation Date, and such adjustment would affect
the liability of ADIC to pay to Interpoint or of Interpoint to pay to ADIC, as
the case may be, any Original Tax Provision, such Original Tax Provision shall

part of or reflected in the Tax Return to which such Original Tax Provision
relates.  ADIC shall pay to Interpoint or Interpoint shall pay to ADIC, as the
case may be, (a) any excess of the Original Tax Provision pursuant to such

ADIC or Interpoint pursuant to this Section 5.02 shall be reduced to reflect

liability taken into account in computing such payment.

Vl.      CARRYBACKS OF ADIC TAX BENEFITS

Disaffiliation Date or (ii) ADIC properly elects to carryback to such earlier
taxable period, then the Original Tax Provision for the taxable period to which
such Tax Benefit is carried back shall. be adjusted accordingly, and (whether
or not an Original Tax Provision existed for the applicable period) Interpoint
shall pay to ADIC the amount of the reduction in Tax liability resulting from
the carryback of such Tax Benefit (to the extent that ADIC does not receive
such amount directly from the appropriate taxing authority).  Such payment
shall be made within thirty (30) days of the receipt by any Interpoint Company
of the tax benefit of any such reduction.  For the purposes of this Article VI,
if for any taxable period ending after the Disaffiliation Date, both Interpoint
and ADIC have Tax Benefits that they can properly elect to carryback, then such
Tax Benefits shall be applied first against any income or tax attributable to
Interpoint or ADIC, as the case may be.  Interpoint then shall pay ADIC the
amount of the additional reduction in Tax liability remaining after that
application to the extent of ADIC's pro rata share of the amount of the
remaining Tax Benefits that can be carried back.  Such pro rata share shall be
the total amount of remaining Tax Benefits that can be carried back multiplied
by a fraction the numerator of which is the amount of the remaining Tax
Benefits of the ADIC Companies and the denominator of which is the sum of the
remaining Tax Benefits of both the ADIC and Interpoint Companies that are
described in the first sentence of this Article VI.

Determination attributable to one or more transactions described in Section
7.01, there is an adjustment to a federal, state, local or foreign Tax Item of
an ADIC Company with respect to a tax period or portion thereof ending on or
before the Disaffiliation Date (other than an adjustment with respect to which
ADIC has borne all resulting increases in Tax liability pursuant to Section
7.03) and as a result of such adjustment there is allowable a net increase in
federal, state, local or foreign Tax Benefits or a net decrease in federal,
state, local or foreign Tax Detriments of an ADIC Company in any tax period or
portion thereof ending after the Disaffiliation Date, ADIC shall pay to
Interpoint the amount of any such reduction together with interest received as

action as may be reasonably necessary to secure the benefit of any reduction in
Income Tax liability, plus interest resulting from such net increase or
decrease (including by filing an amended return or claim for refund) and shall

to the date of the closing of the statute of limitations for any taxable year
of any material ADIC Company under any state, local or foreign Income Tax law
under which there may be a material benefit for which Interpoint may be
entitled to a payment under this section at least thirty (30) days prior to
such date.  Any benefit or interest which is not received by the ADIC Companies

available to the Interpoint Companies, or file any forms or provide any
certificates, reasonably requested in writing by Interpoint either to be
provided to Interpoint or to be filed by the ADIC Companies.

VIII.    TAXES OTHER THAN INCOME TAXES

         ADIC shall pay, and shall indemnify and hold harmless the Interpoint
Companies against, all Taxes, other than income taxes, attributable to the ADIC

IX.      ADMINISTRATIVE PROVISIONS

         9.01.   CONTESTS

         In order to be indemnified under this Agreement a party entitled to be
indemnified under this Agreement for any liability resulting from an adjustment
to Tax Item reportable in any tax period or portion thereof or the imposition
of a Tax shall provide the indemnifying party (at the indemnifying party's
cost) with written notice of any claim or of the commencement of any audit or
proceeding which may result in any such indemnification, together with copies
of all correspondence, notices or other documents relating thereto; shall
provide the indemnifying party with notice of and an opportunity to attend any
meeting with tax authorities regarding such claim, audit or proceeding; and
shall not (unless otherwise required by a proper notice of assessment of levy)
pay, settle, compromise or concede any portion of such claim or issue relating
thereto without the written consent of the indemnifying party and shall, at the
indemnifying party's sole cost (including any reasonable out-of-pocket costs
incurred by the indemnified party) take such action as the indemnifying party
may reasonably request (including the filing of a petition, amended return or
claim for refund) in contesting such claim, provided that the indemnifying
party shall, if so requested, provide an opinion of independent tax counsel or
an independent accounting firm that there exists a reasonable basis for such
contest, and shall assign to the indemnifying party any claim for refund for
any portion of such claim which shall have been paid.  If in the course of a
contest a compromise is offered with respect to offsetting or partially
offsetting issues, the parties agree





                                       11
<PAGE>   12
to negotiate in good faith in an effort to share the benefits of such
compromise.  Any party receiving a refund (or interest attributable thereto) to
which the other party is entitled shall promptly pay such refund and interest
to such other party.

         9.02    COOPERATION AND EXCHANGE OF INFORMATION

         Interpoint and ADIC will provide each other with such cooperation and
information as either of them may reasonably request of the other in filing any
Tax Return, determining a liability for Taxes or a right to refund of Taxes or
in conducting any audit or other proceeding in respect of Taxes, Such
cooperation and information shall include, without limitation, providing copies
of all relevant Tax Returns, together with accompanying schedules and related
workpapers, the computerized tax data base with respect to any Interpoint
Company or ADIC Company, documents relating to rulings or other determinations
by taxing authorities, and records concerning the ownership and tax basis of
property, which either party may possess.  Each party shall make its employees
available on a mutually convenient basis to provide explanations of any
documents or information requested hereunder.  Except as otherwise provided in
this agreement, the party requesting assistance hereunder shall reimburse the
other for any reasonable out-of-pocket costs incurred in providing any Tax
Return, document or other written information, upon receipt of reasonable
documentation of such costs.  Each party will retain all returns, schedules and
workpapers, and all material records or other documents relating thereto, until
the expiration of the statute of limitations (including extensions) of the
taxable years to which such returns and other documents relate and, unless such
Tax Returns and other documents are offered to the other party, until the final
determination of any payments which may be required in respect of such years
under this agreement.  Any information obtained under this Section shall be
kept confidential, except as may be otherwise necessary in connection with the
filing of returns or claims for refund or in conducting any audit or other
proceeding.

         9.03.   STATEMENT OF POSSIBLE CARRYFORWARDS

         Within thirty (30) days before the filing by the Interpoint Affiliated
Group of its consolidated federal income tax return for its taxable year which
includes the Disaffiliation Date and the filing by the Interpoint Affiliated
Group of any state or local consolidated, combined or unitary tax returns
including an ADIC Company for the taxable year which includes the
Disaffiliation Date (and, if requested by ADIC, at any additional time prior to
such dates) , Interpoint will provide ADIC with its estimate of the amount of
carryforwards of losses, credits, or other Tax Items, if any, which may be
available to the ADIC Companies following the Disaffiliation Date, Such
estimate will be for information only, based on Interpoint's best estimate of
the available benefits as of the time such estimate is provided, and no
warranty as to the existence or availability of carryforwards shall be given or
implied.  Interpoint will inform ADIC of any adjustments to such carryforward
determined in connection with the filing of the Interpoint Affiliated Group's
Tax Returns, promptly after such filing, or which may result from any audit or
other proceeding, at the time of a Final Determination with respect thereto.

         9.04    MEANING OF RECEIPT OR REDUCTION

         Any reference in this Agreement to the receipt by a party of an
amount, or a reduction in a tax liability of a party or interest with respect
thereto, shall (except where the context indicates to the contrary) include any
offset or credit against any other tax liability of such party, and shall be
deemed to have been received or refunded at the time such other tax liability
(or interest thereon) would otherwise have been due.

         9.05    CHARACTER AND EFFECT OF PAYMENTS

         All amounts paid pursuant to this Agreement by one party to another,
other than Post Disaffiliation Correlative Amounts, shall be treated by such
parties for all Tax purposes as intercompany settlements of liabilities
existing on or before the Disaffiliation Date.  If, notwithstanding such
treatment by Interpoint and ADIC, as a result of a Final Determination the
federal, state, local or foreign income tax liability of either Interpoint or
ADIC shall be increased as a result of its receipt of a payment pursuant to
this Agreement, or with respect to any payment of a Post Disaffiliation
Correlative Amount, such payment shall be appropriately adjusted (but only to
the extent that the indemnifying party shall have been given the opportunity to
contest such adjustment in accordance with Section 9.01 hereof) so that the
amount of such payment, as adjusted, reduced by the amount of all Income Taxes
payable with respect to the receipt thereof (but taking into account all
correlative tax benefits resulting from the payment of such Income Taxes) ,
shall equal the amount of the payment which the party receiving such payment
would otherwise be entitled to receive pursuant to this Agreement.

         This agreement constitutes the entire agreement between the parties
concerning the subject matter hereof and supersedes (to the extent not
incorporated herein) all other agreements, whether or not written, in respect

the ADIC Companies, on the other hand.  This Agreement may not be amended
except by an agreement in writing, signed by the parties hereto.

consultants, agents, advisors and independent contractors who provide services
to the Company and its Subsidiaries.

                             SECTION 6. AWARDS

6.1      FORM AND GRANT OF AWARDS

         The Plan Administrator shall have the authority, in its sole
discretion, to determine the type or types of Awards to be made under the Plan.
Such Awards may consist of Incentive Stock Options and/or Nonqualified Stock
Options. Awards may be granted singly or in combination.

6.2      ACQUIRED COMPANY AWARDS

         Notwithstanding anything in the Plan to the contrary, the Plan
Administrator may grant Awards under the Plan in substitution for awards issued
under other plans, or assume under the Plan awards issued under other plans, if
the other plans are or were plans of other acquired entities ("Acquired
Entities") (or the parent of the Acquired Entity) and the new Award is
substituted, or the old award is assumed, by reason of a merger, consolidation,
acquisition of property or of stock, reorganization or liquidation (the
"Acquisition Transaction"). In the event that a written agreement pursuant to
which the Acquisition Transaction is completed is approved by the Board and said
agreement sets forth the terms and conditions of the substitution for or
assumption of outstanding awards of the Acquired Entity, said terms and
conditions shall be deemed to be the action of the Plan Administrator without
any further action by the Plan Administrator, except as may be required for
compliance with Rule 16b-3 under the Exchange Act, and the persons holding such
Awards shall be deemed to be Participants and Holders.

                       SECTION 7. AWARDS OF OPTIONS

7.1      GRANT OF OPTIONS

         The Plan Administrator is authorized under the Plan, in its sole
discretion, to issue Options as Incentive Stock Options or as Nonqualified Stock
Options, which shall be appropriately designated.

7.2      OPTION EXERCISE PRICE

         The exercise price for shares purchased under an Option shall be as
determined by the Plan Administrator, but shall not be less than 100% of the
Fair Market Value of the Common Stock on the Grant Date.

7.3      TERM OF OPTIONS

         The term of each Option shall be as established by the Plan
Administrator or, if not so established, shall be five years from the Grant
Date.

7.4      EXERCISE OF OPTIONS

         The Plan Administrator shall establish and set forth in each instrument
that evidences an Option the time at which or the installments in which the
Option shall become exercisable, which provisions may be waived or modified by
the Plan Administrator at any time. If not so established in the instrument
evidencing the Option, the Option will become exercisable according to the
following schedule, which may be waived or modified by the Plan Administrator at
any time:

<TABLE>

Service With the Company or Its Subsidiaries         Percent of Total Option

</TABLE>

         To the extent that the right to purchase shares has accrued thereunder,
an Option may be exercised from time to time by written notice to the Company,
in accordance with procedures established by the Plan Administrator, setting
forth the number of shares with respect to which the Option is being exercised
and accompanied by payment in full as described in Section 7.5. The Plan
Administrator may determine at any time that an Option may not be exercised as
to less than 100 shares at any one time (or the lesser number of remaining
shares covered by the Option).

                                       -7-
<PAGE>   8
7.5      PAYMENT OF EXERCISE PRICE

         The exercise price for shares purchased under an Option shall be paid
in full to the Company by delivery of consideration equal to the product of the
Option exercise price and the number of shares purchased. Such consideration
must be paid in cash or check, or, unless the Plan Administrator at any time
determines otherwise, a combination of cash and/or check and one or both of the
following alternative forms: (a) tendering (either actually or, if and so long
as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange
Act, by attestation) Common Stock already owned by the Holder for at least six
months (or any shorter period necessary to avoid a charge to the Company's
earnings for financial reporting purposes) having a Fair Market Value on the day
prior to the exercise date equal to the aggregate Option exercise price; or (b)
if and so long as the Common Stock is registered under Section 12(b) or 12(g) of
the Exchange Act, delivery of a properly executed exercise notice, together with
irrevocable instructions, to (i) a brokerage firm designated by the Company to
deliver promptly to the Company the aggregate amount of sale or loan proceeds to
pay the Option exercise price and any withholding tax obligations that may arise
in connection with the exercise and (ii) the Company to deliver the certificates
for such purchased shares directly to such brokerage firm, all in accordance
with the regulations of the Federal Reserve Board. In addition, the exercise
price for shares purchased under an Option may be paid either singly or in
combination with one or more of the alternative forms of payment authorized by
this Section 7.5, by (y) a promissory note delivered pursuant to Section 10 or
(z) such other consideration as the Plan Administrator may permit.

7.6      POST-TERMINATION EXERCISES

         The Plan Administrator shall establish and set forth in each instrument
that evidences an Option whether the Option will continue to be exercisable, and
the terms and conditions of such exercise, if a Holder ceases to be employed by,
or to provide services to, the Company or its Subsidiaries, which provisions may
be waived or modified by the Plan Administrator at any time. If not so
established in the instrument evidencing the Option, the Option will be
exercisable according to the following terms and conditions, which may be waived
or modified by the Plan Administrator at any time.

         In case of termination of the Holder's employment or services other
than by reason of death or Cause, the Option shall be exercisable, to the extent
of the number of shares purchasable by the Holder at the date of such
termination, only within three months after the date the Holder ceases to be an
employee, director, officer, consultant, agent, advisor or independent
contractor of the Company or a Subsidiary if termination of the Holder's
employment or services is for any reason other than Disability and only within
one year after the date of such termination by reason of Disability, but in no
event later than the remaining term of the Option. Any Option exercisable at the
time of the Holder's death may be exercised, at any time or from time to time
within one year after the date of death, but in no event later than the
remaining term of the Option, to the extent of the number of shares purchasable
by the Holder at the date of the Holder's death, by the personal representative
of the Holder's estate, the person(s) to whom the Holder's rights under the
Award have passed by will or the applicable laws of descent and distribution or
the beneficiary designated pursuant to Section 11. Any portion of an Option that
is not exercisable on the date of termination of the Holder's employment or
services shall terminate on such date, unless the Plan

                                      -8-
<PAGE>   9
Administrator determines otherwise. In case of termination of the Holder's
employment or services for Cause, the Option shall automatically terminate upon
first notification to the Holder of such termination, unless the Plan
Administrator determines otherwise. If a Holder's employment or services with
the Company are suspended pending an investigation of whether the Holder shall
be terminated for Cause, all the Holder's rights under any Option likewise shall
be suspended during the period of investigation.

         A transfer of employment or services between or among the Company and
its Subsidiaries shall not be considered a termination of employment or
services. The effect of a Company-approved leave of absence on the terms and
conditions of an option shall be determined by the Plan Administrator, in its
sole discretion.

              SECTION 8. INCENTIVE STOCK OPTION LIMITATIONS

         To the extent required by Section 422 of the Code, Incentive Stock
Options shall be subject to the following additional terms and conditions:

8.1      DOLLAR LIMITATION

         To the extent the aggregate Fair Market Value (determined as of the
Grant Date) of Common Stock with respect to which Incentive Stock Options are
exercisable for the first time during any calendar year (under the Plan and all
other stock option plans of the Company) exceeds $100,000, such portion in
excess of $100,000 shall be treated as a Nonqualified Stock Option. In the event
the Participant holds two or more such Options that become exercisable for the
first time in the same calendar year, such limitation shall be applied on the
basis of the order in which such Options are granted.

8.2      10% SHAREHOLDERS

         If a Participant owns more than 10% of the total voting power of all
classes of the Company's stock, then the exercise price per share of an
Incentive Stock Option shall not be less than 110% of the Fair Market Value of
the Common Stock on the Grant Date and the Option term shall not exceed five
years. The determination of 10% ownership shall be made in accordance with
Section 422 of the Code.

8.3      ELIGIBLE EMPLOYEES

         Individuals who are not employees of the Company or one of its parent
corporations or subsidiary corporations may not be granted Incentive Stock
Options. For purposes of this Section 8.3, "parent corporation" and "subsidiary
corporation" shall have the meanings attributed to those terms for purposes of
Section 422 of the Code.

8.4      TERM

         The term of an Incentive Stock Option shall not exceed 10 years.

                                       -9-
<PAGE>   10
8.5      EXERCISABILITY

         To qualify for Incentive Stock Option tax treatment, an Option
designated as an Incentive Stock Option must be exercised within three months
after termination of employment for reasons other than death, except that, in
the case of termination of employment due to total disability, such Option must
be exercised within one year after such termination. Employment shall not be
deemed to continue beyond the first 90 days of a leave of absence unless the
Participant's reemployment rights are guaranteed by statute or contract. For
purposes of this Section 8.5, "total disability" shall mean a mental or physical
impairment of the Participant which is expected to result in death or which has
lasted or is expected to last for a continuous period of 12 months or more and
which causes the Participant to be unable, in the opinion of the Company and two
independent physicians, to perform his or her duties for the Company and to be
engaged in any substantial gainful activity. Total disability shall be deemed to
have occurred on the first day after the Company and the two independent
physicians have furnished their opinion of total disability to the Plan
Administrator.

8.6      TAXATION OF INCENTIVE STOCK OPTIONS

         In order to obtain certain tax benefits afforded to Incentive Stock
Options under Section 422 of the Code, the Participant must hold the shares
issued upon the exercise of an Incentive Stock Option for two years after the
Grant Date of the Incentive Stock Option and one year from the date of exercise.
A Participant may be subject to the alternative minimum tax at the time of
exercise of an Incentive Stock Option. The Plan Administrator may require a
Participant to give the Company prompt notice of any disposition of shares
acquired by the exercise of an Incentive Stock Option prior to the expiration of
such holding periods.

8.7      PROMISSORY NOTES

         The amount of any promissory note delivered pursuant to Section 10 in
connection with an Incentive Stock Option shall bear interest at a rate
specified by the Plan Administrator but in no case less than the rate required
to avoid imputation of interest (taking into account any exceptions to the
imputed interest rules) for federal income tax purposes.

                      SECTION 9. AWARDS OF OPTIONS TO NONEMPLOYEE 
                                 DIRECTORS

         Notwithstanding any other provision of the Plan to the contrary, grants
to Eligible Directors shall be made only pursuant to the terms and conditions
set forth below.

                                      -10-
<PAGE>   11
9.1      ANNUAL GRANTS

         Commencing with the Company's 1997 Annual Meeting of Shareholders, each
Eligible Director shall automatically receive a grant of an Option to purchase
500 shares of Common Stock immediately following each year's Annual Meeting of
Shareholders ("Annual Grants"). Annual Grants shall vest and become exercisable
upon the optionee's continued service as a director until the next Annual
Meeting of Shareholders after the Grant Date.

9.2      INITIAL GRANTS

         Each Eligible Director shall automatically receive a grant of an Option
to purchase 5,500 shares of Common Stock immediately following his or her
initial election or appointment to the Board ("Initial Grants"). Initial Grants
shall vest and become exercisable as follows: Options for 1,375 shares shall
become exercisable on and after one year after the Grant Date, and Options for
an additional 1,375 shares shall become exercisable on and after each of the
three succeeding anniversaries of the Grant Date.

9.3      NONQUALIFIED STOCK OPTIONS; TERM OF OPTIONS

         Options granted to an Eligible Director under the Plan shall constitute
Nonqualified Stock Options. The term of each Option granted under this Section 9
shall be five years from the Grant Date.

9.4      OPTION EXERCISE PRICE

         The exercise price for shares purchased under an Option granted under
this Section 9 shall be the Fair Market Value of the Common Stock on the Grant
Date.

9.5      POST-TERMINATION EXERCISES

         In case of termination of the Holder's services other than by reason of
death or Cause, the Option shall be exercisable, to the extent of the number of
shares purchasable by the Holder at the date of such termination, only within
three months after the date the Holder ceases to be a director of the Company if
such termination is for reasons other than Disability and only within one year
if such termination is by reason of Disability, but in no event later than the
remaining term of the Option. Any Option exercisable at the time of the Holder's
death may be exercised, to the extent of the number of shares purchasable by the
Holder at the date of the Holder's death, by the personal representative of the
Holder's estate entitled thereto at any time or from time to time within one
year after the date of death, but in no event later than the remaining term of
the Option. In case of termination of the Holder's services for Cause, the
Option shall automatically terminate upon first notification to the Holder of
such termination. If a Holder's services with the Company are suspended pending
an investigation of whether the Holder shall be terminated for Cause, all the
Holder's rights under any Option likewise shall be suspended during the period
of investigation.

                                      -11-
<PAGE>   12
9.6      CORPORATE TRANSACTION

         In the event of a Corporate Transaction, each Award that is at the time
outstanding shall automatically accelerate so that each such Award shall,
immediately prior to the specified effective date for the Corporate Transaction,
become 100% vested, except that such acceleration will not occur if, in the
opinion of the Company's accountants, it would render unavailable "pooling of
interests" accounting for a Corporate Transaction that would otherwise qualify
for such accounting treatment. All such Awards not exercised prior to that time
shall terminate and cease to remain outstanding immediately following the
consummation of the Corporate Transaction.

9.7      AVAILABILITY OF SHARES

         The Options provided for in this Section 9 are subject to the
availability of shares under the Plan. If at the date of any grant under this
Section 9 there are insufficient shares of Common Stock available to satisfy the
grants in whole, then the shares available shall be divided by the number of
Eligible Directors then entitled to a grant and each such Eligible Director
shall be granted an Option for that number of shares.

9.8      OTHER TERMS APPLICABLE

         Except as otherwise provided in this Section 9, Options granted to
Eligible Directors shall be subject to the terms and conditions of the Plan
applicable to other Participants.

                SECTION 10. LOANS, INSTALLMENT PAYMENTS AND
                              LOAN GUARANTEES

         To assist a Holder (including a Holder who is an officer or director of
the Company) in acquiring shares of Common Stock pursuant to an Award granted
under the Plan, the Plan Administrator, in its sole discretion, may authorize,
either at the Grant Date or at any time before the acquisition of Common Stock
pursuant to the Award, (a) the extension of a loan to the Holder by the Company,
(b) the payment by the Holder of the purchase price, if any, of the Common Stock
in installments, or (c) the guarantee by the Company of a loan obtained by the
Holder from a third party. The terms of any loans, installment payments or loan
guarantees, including the interest rate and terms of repayment, will be subject
to the Plan Administrator's discretion. Loans, installment payments and loan
guarantees may be granted with or without security. The maximum credit available
is the purchase price, if any, of the Common Stock acquired, plus the maximum
federal and state income and employment tax liability that may be incurred in
connection with the acquisition.

                         SECTION 11. ASSIGNABILITY

         No Award granted under the Plan may be pledged, assigned or transferred
by the Holder other than by will or by the laws of descent and distribution, and
during the Holder's lifetime, such Awards may be exercised only by the Holder.
Notwithstanding the foregoing, and to the extent permitted by Section 422 of the
Code, the Plan Administrator, in its sole discretion, may permit such
assignment, transfer and exercisability and may permit a Holder of such Awards
to designate

                                      -12-
<PAGE>   13
a beneficiary who may exercise the Award or receive compensation under the Award
after the Holder's death; provided, however, that any Award so assigned or
transferred shall be subject to all the same terms and conditions contained in
the instrument evidencing the Award.

                          SECTION 12. ADJUSTMENTS

12.1     ADJUSTMENT OF SHARES

         In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or capital structure
results in (a) the outstanding shares, or any securities exchanged therefor or
received in their place, being exchanged for a different number or class of
securities of the Company or of any other corporation or (b) new, different or
additional securities of the Company or of any other corporation being received
by the holders of shares of Common Stock of the Company, then the Plan
Administrator shall make proportional adjustments in (i) the maximum number and
class of securities subject to the Plan as set forth in Section 4.1, (ii) the
number and class of securities that may be made subject to Awards to any
individual Participant as set forth in Sections 4.2, 9.1, 9.2 and 9.3 and (iii)
the number and class of securities subject to any outstanding Award and the per
share price of such securities, without any change in the aggregate price to be
paid therefor. The determination by the Plan Administrator as to the terms of
any of the foregoing adjustments shall be conclusive and binding.

12.2     CORPORATE TRANSACTION

         Except as otherwise provided in the instrument that evidences the
Award, in the event of a Corporate Transaction, each Award that is at the time
outstanding shall automatically accelerate so that each such Award shall,
immediately prior to the specified effective date for the Corporate Transaction,
become 100% vested, except that such acceleration will not occur if, in the
opinion of the Company's accountants, it would render unavailable "pooling of
interests" accounting for a Corporate Transaction that would otherwise qualify
for such accounting treatment. Except for Options granted pursuant to Section 9,
such Award shall not so accelerate, if and to the extent (a) such Award is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation or parent thereof (the "Successor Corporation") or to be replaced
with a comparable award for the purchase of shares of the capital stock of the
Successor Corporation or, (b) such Award is to be replaced with a cash incentive
program of the Successor Corporation that preserves the spread existing at the
time of the Corporate Transaction and provides for subsequent payout in
accordance with the same vesting schedule applicable to such Award. The
determination of Award comparability under clause (a) above shall be made by the
Plan Administrator, and its determination shall be conclusive and binding. All
such Awards shall terminate and cease to remain outstanding immediately
following the consummation of the Corporate Transaction, except to the extent
such Awards (other than Options granted pursuant to Section 9) are assumed by
the Successor Corporation. Any such Awards that are assumed or replaced in the
Corporate Transaction and do not otherwise accelerate at that time shall be
accelerated in the event the Holder's employment or services should subsequently
terminate within two years following such Corporate Transaction, unless such
employment or services are

                                      -13-
<PAGE>   14
terminated by the Successor Corporation for Cause or by the Holder voluntarily
without Good Reason. Notwithstanding the foregoing, no Incentive Stock Option
shall become exercisable pursuant to this Section 12.2 without the Holder's
consent, if the result would be to cause such Option not to be treated as an
Incentive Stock Option (whether by reason of the annual dollar limitation
described in Section 8.1 or otherwise).

12.3     FURTHER ADJUSTMENT OF AWARDS

         Subject to the preceding Section 12.2, the Plan Administrator shall
have the discretion, exercisable at any time before a sale, merger,
consolidation, reorganization, liquidation or change in control of the Company,
as defined by the Plan Administrator, to take such further action as it
determines to be necessary or advisable, and fair and equitable to Participants,
with respect to Awards (other than Options granted pursuant to Section 9). Such
authorized action may include (but shall not be limited to) establishing,
amending or waiving the type, terms, conditions or duration of, or restrictions
on, Awards so as to provide for earlier, later, extended or additional time for
exercise, alternate forms and amounts of payments and other modifications, and
the Plan Administrator may take such actions with respect to all Participants,
to certain categories of Participants or only to individual Participants. The
Plan Administrator may take such actions before or after granting Awards to
which the action relates and before or after any public announcement with
respect to such sale, merger, consolidation, reorganization, liquidation or
change in control that is the reason for such action.

12.4     LIMITATIONS

         The grant of Awards will in no way affect the Company's right to
adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

                             SECTION 13. WITHHOLDING

         The Company may require the Holder to pay to the Company the amount of
any withholding taxes that the Company is required to withhold with respect to
the grant or exercise of any Award. In such instances, subject to the Plan and
applicable law and unless the Plan Administrator determines otherwise, the
Holder may satisfy withholding obligations, in whole or in part, by paying cash,
by electing to have the Company withhold shares of Common Stock or by
transferring shares of Common Stock to the Company, in such amounts as are
equivalent to the Fair Market Value of the withholding obligation. The Company
shall have the right to withhold from any shares of Common Stock issuable
pursuant to an Award or from any cash amounts otherwise due or to become due
from the Company to the Participant an amount equal to such taxes. The Company
may also deduct from any Award any other amounts due from the Participant to the
Company or a Subsidiary.

                 SECTION 14. AMENDMENT AND TERMINATION OF
                                   PLAN

14.1     AMENDMENT OF PLAN

         The Plan may be amended by the shareholders of the Company. The Board
may also amend the Plan in such respects as it shall deem advisable; however, to
the extent required for compliance with Section 422 of the Code or any
applicable law or regulation, shareholder approval will be required for any
amendment that will (a) increase the aggregate number of shares as to which
Awards may be granted, (b) modify the class of employees eligible to receive
Awards, or (c) otherwise require shareholder approval under any applicable law
or regulation.

14.2     TERMINATION OF PLAN

         The Company's shareholders or the Board may suspend or terminate the
Plan at any time. The Plan will have no fixed expiration date; provided,
however, that no Incentive Stock Options may be granted more than 10 years after
the earlier of the Plan's adoption by the Board or approval by the shareholders.

14.3     CONSENT OF HOLDER

         The amendment or termination of the Plan shall not, without the consent
of the Holder of any Award under the Plan, impair or diminish any rights or
obligations under any Award theretofore granted under the Plan.

         Any change or adjustment to an outstanding Incentive Stock Option shall
not, without the consent of the Holder, be made in a manner so as to constitute
a "modification" that would cause such Incentive Stock Option to fail to
continue to qualify as an Incentive Stock Option.

                            SECTION 15. GENERAL

15.1     AWARD AGREEMENTS

         Awards granted under the Plan shall be evidenced by a written agreement
which shall contain such terms, conditions, limitations and restrictions as the
Plan Administrator shall deem advisable and which are not inconsistent with the
Plan.

15.2     CONTINUED EMPLOYMENT OR SERVICES; RIGHTS IN AWARDS

         None of the Plan, participation in the Plan as a Participant or any
action of the Plan Administrator taken under the Plan shall be construed as
giving any Participant or employee of the Company any right to be retained in
the employ of the Company or limit the Company's right to terminate the
employment or services of the Participant.

15.3     REGISTRATION; CERTIFICATES FOR SHARES

         The Company shall be under no obligation to any Participant to register
for offering or resale or to qualify for exemption under the Securities Act, or
to register or qualify under state

                                      -15-
<PAGE>   16
securities laws, any shares of Common Stock, security or interest in a security
paid or issued under, or created by, the Plan, or to continue in effect any such
registrations or qualifications if made. The Company may issue certificates for
shares with such legends and subject to such restrictions on transfer and
stop-transfer instructions as counsel for the Company deems necessary or
desirable for compliance by the Company with federal and state securities laws.

         Inability of the Company to obtain, from any regulatory body having
jurisdiction, the authority deemed by the Company's counsel to be necessary for
the lawful issuance and sale of any shares hereunder or the unavailability of an
exemption from registration for the issuance and sale of any shares hereunder
shall relieve the Company of any liability in respect of the nonissuance or sale
of such shares as to which such requisite authority shall not have been
obtained.

15.4     NO RIGHTS AS A SHAREHOLDER

         No Award shall entitle the Holder to any dividend, voting or other
right of a shareholder unless and until the date of issuance under the Plan of
the shares that are the subject of such Award, free of all applicable
restrictions.

15.5     COMPLIANCE WITH LAWS AND REGULATIONS

         Notwithstanding anything in the Plan to the contrary, the Board, in its

forth the number of shares with respect to which the Option is being exercised
and accompanied by payment in full as described in Section 7.5 of the Plan.

7.5      PAYMENT OF EXERCISE PRICE

         The exercise price for shares purchased under an Option SHALL be paid
in full to the Company by delivery of consideration equal to the product of the
Option exercise price and the number of shares purchased. Such consideration
must be paid in cash or check and/or one or more of the following alternative
forms: (i) Common Stock already owned by the Holder for at least six months (or
any shorter period necessary to avoid a charge to the Company's earnings for
financial reporting purposes) having a Fair Market Value on the day prior to the
exercise date equal to the aggregate Option exercise price or (ii) if the Common
Stock is publicly traded, delivery of a properly executed exercise notice,
together with irrevocable 

                                       -7-
<PAGE>   13
instructions, to (a) a brokerage firm designated by the Company to deliver
promptly to the Company the aggregate amount of sale or loan proceeds to pay the
Option exercise price and any withholding tax obligations that may arise in
connection with the exercise and (b) the Company to deliver the certificates for
such purchased shares directly to such brokerage firm, all in accordance with
the regulations of the Federal Reserve Board.

7.6      POST-TERMINATION EXERCISES

         The Plan Administrator shall establish and set forth in each instrument
that evidences an Option whether the Option will continue to be exercisable, and
the terms and conditions of such exercise, if a Holder ceases to be employed by,
or to provide services to, the Company or its Subsidiaries, which provisions may
be waived or modified by the Plan Administrator at any time. If not so
established in the instrument evidencing the Option, the Option will be
exercisable according to the following terms and conditions, which may be waived
or modified by the Plan Administrator at any time. In case of termination of the
Holder's employment or services other than by reason of death or Cause, the
Option shall be exercisable, to the extent of the number of shares purchasable
by the Holder at the date of such termination, only within three months after
the date of such termination for reasons other than Disability and only within
one year after the date of such termination by reason of Disability, but in no
event later than the remaining term of the Option. Any Option exercisable at the
time of the Holder's death may be exercised, to the extent of the number of
shares purchasable by the Holder at the date of the Holder's death, by the
personal representative of the Holder's estate entitled thereto at any time or
from time to time within one year after the date of death, but in no event later
than the remaining term of the Option. In case of termination of the Holder's
employment or services for Cause, the Option shall automatically terminate upon
first notification to the Holder of such termination, unless the Plan
Administrator determines otherwise. If a Holder's employment or services with
the Company are suspended pending an investigation of whether the Holder shall
be terminated for Cause, all the Holder's rights under any Option likewise shall
be suspended during the period of investigation. A transfer of employment or
services between or among the Company and its Subsidiaries shall not be
considered a termination of employment or services. Unless the Plan
Administrator determines otherwise, a leave of absence approved in accordance
with Company procedures shall not be considered a termination of employment or
services, except that with respect to Incentive Stock Options such leave of
absence shall be subject to any requirements of Section 422 of the Code.

                  SECTION 8. INCENTIVE STOCK OPTION LIMITATIONS

         To the extent required by Section 422 of the Code, Incentive Stock
Options shall be subject to the following additional terms and conditions:

8.1      DOLLAR LIMITATION

         To the extent the aggregate Fair Market Value (determined as of the
Grant Date) of Common Stock with respect to which Incentive Stock Options are
exercisable for the first time during any calendar year (under the Plan and all
other stock option plans of the 

                                       -8-
<PAGE>   14
Company) exceeds $100,000, such portion in excess of $100,000 shall be treated
as a Nonqualified Stock Option, unless such annual limitation is modified or
eliminated under Code Section 422. In the event the Participant holds two or
more such Options that become exercisable for the first time in the same
calendar year, such limitation shall be applied on the basis of the order in
which such Options are granted.

8.2      10% SHAREHOLDERS

         If a Participant owns 10% or more of the total voting power of all
classes of the Company's stock, then the exercise price per share of an
Incentive Stock Option shall not be less than 110% of the Fair Market Value of
the Common Stock on the Grant Date and the OPTION term shall not exceed five
years.

8.3      ELIGIBLE EMPLOYEES

         Individuals who are not employees of the Company or one of its parent
corporations or subsidiary corporations may not be granted Incentive Stock
Options. For purposes of this Section 8.3 of the Plan, "parent corporation" and
"subsidiary corporation" shall have the meanings attributed to those terms for
purposes of Section 422 of the Code.

8.4      TERM

         The term of an Incentive Stock Option shall not exceed 10 years.

8.5      EXERCISABILITY

         An Option designated as an Incentive Stock Option must be exercised
within three months after termination of employment for reasons other than death
to qualify for Incentive Stock Option tax treatment, except that in the case of
termination of employment due to Disability, such Option must be exercised
within one year after such termination.

8.6      TAXATION OF INCENTIVE STOCK OPTION

         In order to obtain certain tax benefits afforded to Incentive Stock
Options under Section 422 of the Code, the Participant must hold the shares
issued upon the exercise of an Incentive Stock Option for two years after the
date of grant of the Incentive Stock Option and one year from the date of
exercise. A Participant may be subject to the alternative minimum tax at the
time of exercise of an Incentive Stock Option. The Committee may require a
Participant to give the Company prompt notice of any disposition of shares
acquired by the exercise of an Incentive Stock Option prior to the expiration of
such holding periods.

              SECTION 9. AWARDS OF OPTIONS TO NONEMPLOYEE DIRECTORS

         Notwithstanding any other provision of the Plan to the contrary, grants
to Eligible Directors shall be made only pursuant to the terms and conditions
set forth below. All grants

                                       -9-
<PAGE>   15
made under this Section 9 prior to shareholder approval of the Plan shall be
subject to such shareholder approval.

9.1      ORIGINAL GRANTS

         Each Eligible Director who is in office on the date the Plan is adopted
by the Board shall automatically receive a grant of an Option to purchase 500
shares of Common Stock immediately following the Board's adoption of the Plan
("Original Grants"). Original Grants shall vest and become exercisable upon the
optionee's continued service as a director until the Company's first Annual
Meeting of Shareholders after the Grant Date.

9.2      ANNUAL GRANTS

         Commencing with the Company's 1996 Annual Meeting of Shareholders, each
Eligible Director shall automatically receive a grant of an Option to purchase
500 shares of Common Stock immediately following each year's Annual Meeting of
Shareholders ("Annual Grants"). Annual Grants shall vest and become exercisable
upon the optionee's continued service as a director until the next Annual
Meeting of Shareholders after the Grant Date.

9.3      INITIAL GRANTS

         Each Eligible Director shall automatically receive a grant of an Option
to purchase 5,500 shares of Common Stock immediately following his or her
initial election or appointment to the Board ("Initial Grants"). Initial Grants
shall vest and become exercisable as follows: Options for 1,375 shares shall
become exercisable on and after one year after the Grant Date, and Options for
an additional 1,375 shares shall become exercisable on and after each of the
three succeeding anniversaries of the Grant Date.

9.4      NONQUALIFIED STOCK OPTIONS; TERM OF OPTIONS

         Options granted to an Eligible Director under the Plan shall constitute
Nonqualified Stock Options. The term of each Option granted under this Section 9
shall be five years from the Grant Date.

9.5      OPTION EXERCISE PRICE

         The exercise price for shares purchased under an Option granted under
this Section 9 shall be the Fair Market Value of the Common Stock on the Grant
Date.

9.6      POST-TERMINATION EXERCISES

         In case of termination of the Holder's services other than by reason of
death or Cause, the Option shall be exercisable, to the extent of the number of
shares purchasable by the Holder at the date of such termination, only within
three months after the date the Holder ceases to be director of the Company if
such termination is for reasons other than Disability and only within one year
if such termination is by reason of Disability, but in no event later than the
remaining term of the Option. Any Option exercisable at the time of the Holder's

                                      -10-
<PAGE>   16
death may be exercised, to the extent of the number of shares purchasable by the
Holder at the date of the Holder's death, by the personal representative of the
Holder's estate entitled thereto at any time or from time to time within one
year after the date of death, but in no event later than the remaining term of
the Option. In case of termination of the Holder's services for Cause, the
Option shall automatically terminate upon first notification to the Holder of
such termination. If a Holder's services with the Company are suspended pending
an investigation of whether the Holder shall be terminated for Cause, all the
Holder's rights under any Option likewise shall be suspended during the period
of investigation.

9.7      CORPORATE TRANSACTION

         In the event of any Corporate Transaction, each Option that is at the
time outstanding shall automatically accelerate so that each such Option shall,
immediately prior to the specified effective date for the Corporate Transaction,
become 100% vested, except that such acceleration will not occur if, in the
opinion of the Company's accountants, it would render unavailable "pooling of
interests" accounting for a Corporate Transaction that would otherwise qualify
for such accounting treatment. All such Options not exercised prior to that time
shall terminate and cease to remain outstanding immediately following the
consummation of the Corporate Transaction.

9.8      AVAILABILITY OF SHARES

         The Options provided for in this Section 9 are subject to the
availability of shares under the Plan. If at the date of any grant under this
Section 9 there are insufficient shares of Common Stock available to satisfy the
grants in whole, then the shares available shall be divided by the number of
Eligible Directors then entitled to a grant and each such Eligible Director
shall be granted an Option for that number of shares.

9.9      OTHER TERMS APPLICABLE

         Except as otherwise provided in this Section 9, Options granted to
Eligible Directors shall be subject to the terms and conditions of the Plan
applicable to other Participants.

                     SECTION 10. LOANS, LOAN GUARANTEES AND
                              INSTALLMENT PAYMENTS

         To assist a Holder (including a Holder who is an officer or director of
the Company) in acquiring shares of Common Stock pursuant to an Award granted
under the Plan other than an Option granted pursuant to Section 9 of the Plan,
the Plan Administrator may authorize, either at the Grant Date or at any time
before the acquisition of Common Stock pursuant to the Award, (i) the extension
of a loan to the Holder by the Company, (ii) the payment by the Holder of the
purchase price, if any, of the Common stock in installments, or (iii) the
guarantee by the Company of a loan obtained by the grantee from a third party.
The terms of any loans, installment payments or guarantees, including the
interest rate and terms of repayment, will be subject to the Plan
Administrator's discretion. Loans, installment payments and guarantees may be
granted with or without security. The maximum credit available is the 

                                      -11-
<PAGE>   17
purchase price, if any, of the Common Stock acquired plus the maximum federal
and state income and employment tax liability that may be incurred in connection
with the acquisition.

                            SECTION 11. ASSIGNABILITY

         No Option granted under the Plan may be assigned or transferred by the
Holder other than by will or by the laws of descent and distribution, and during
the Holder's lifetime, such Awards may be exercised only by the Holder.
Notwithstanding the foregoing, with respect to Awards other than Options granted
pursuant to Section 9 of the Plan, and to the extent permitted by Rule 16b-3
under the Exchange Act and Section 422 of the Code, the Plan Administrator, in
its sole discretion, may permit such assignment, transfer and exercisability and
may permit a Holder of such Awards to designate a beneficiary who may exercise
the Award after the Holder's death. With respect to Options granted pursuant to
Section 9 of the Plan, and to the extent permitted by Rule 16b-3 under the
Exchange Act as then applicable to the Company's employee benefit plans, such
Options may be transferred or assigned by gift or other transfer to either (i)
any trust or estate in which the original award recipient or such person's
spouse or other immediate family member has a substantial beneficial interest or
(ii) a spouse or other immediate family member, provided that such a transfer
would continue to require such awards to be disclosed pursuant to Item 403 of
Regulation S-K under the Securities Act of 1933, as amended.

                        SECTION 12. ADJUSTMENTS

12.1     ADJUSTMENT OF SHARES

         In the event that at any time or from time to time a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or capital structure
results in (i) the outstanding shares, or any securities exchanged therefor or
received in their place, being exchanged for a different number or class of
securities of the Company or of any other corporation or (ii) new, different or
additional securities of the Company or of any other corporation being received
by the holders of shares of Common Stock of the Company, then the Plan
Administrator shall make proportional adjustments in (a) the maximum number and
class of securities subject to the Plan as set forth in Section 4.1 of the Plan,
(b) the number and class of securities that may be made subject to individual
Awards as set forth in Section 9 of the Plan, and (c) the number and class of
securities subject to any outstanding Award made pursuant to Section 9 of the
Plan and the per share price of such securities, without any change in the
aggregate price to be paid therefor, and the Plan Administrator, in its sole
discretion. shall make such equitable adjustments as it shall deem appropriate
in the circumstances in (y) the maximum number and class of securities that may
be made subject to Awards to any individual Participant as set forth in Section
4.2 of the Plan and (z) the number and class of securities that are subject to
any outstanding Award (other than Options granted pursuant to Section 9 of the
Plan) and the per share price of such securities, without any change in the
aggregate price to be paid therefor. The determination by the Plan Administrator
as to the terms of any of the foregoing adjustments shall be conclusive and
binding.

                                      -12-
<PAGE>   18
12.2     CORPORATE TRANSACTION

         Except as otherwise provided in the instrument that evidences the
Award, in the event of any Corporate Transaction, each Option that is at the
time outstanding shall automatically accelerate so that each such Award shall,
immediately prior to the specified effective date for the Corporate Transaction,
become 100% vested, except that such acceleration will not occur if in the
opinion of the Company's accountants it would render unavailable "pooling of
interest" accounting for a Corporate Transaction that would otherwise qualify
for such accounting treatment. Except for Options granted pursuant to Section 9
of the Plan, such Award shall not so accelerate if and to the extent: (i) such
Award is, in connection with the Corporate Transaction, either to be assumed by
the successor corporation or parent thereof or to be replaced with a comparable
award for the purchase of shares of the capital stock of the successor
corporation or its parent corporation, (ii) such Award is to be replaced with a
cash incentive program of the successor corporation that preserves the spread
existing at the time of the Corporate Transaction and provides for subsequent
payout in accordance with the same vesting schedule applicable to such Award, or
(iii) the acceleration of such Award is subject to other limitations imposed by
the instrument evidencing the Award. The determination of Award comparability
under clause (i) above shall be made by the Plan Administrator, and its
determination shall be conclusive and binding. All such Awards shall terminate
and cease to remain outstanding immediately following the consummation of the
Corporate Transaction, except to the extent such Awards (other than Options
granted pursuant to Section 9 of the Plan) are assumed by the successor
corporation or its parent corporation. Any such Awards that are assumed or
replaced in the Corporate Transaction and do not otherwise accelerate at that
time shall be accelerated in the event the Holder's employment or services
should subsequently terminate within two years following such Corporate
Transaction, unless such employment or services are terminated by the Company
for Cause or by the Holder voluntarily without Good Reason. Notwithstanding the
foregoing, no Incentive Stock Option shall become exercisable pursuant to this
Section 12.2 without the Holder's consent, if the result would be to cause such
Option not to be treated as an Incentive Stock Option (whether by reason of the
annual limitation described in Section 8.1 of the Plan or otherwise).

12.3     FURTHER ADJUSTMENT OF AWARDS

         Subject to the preceding Section 12.2 of the Plan, the Plan
Administrator shall have the discretion, exercisable at any time before a sale,
merger, consolidation, reorganization, liquidation or change in control of the
Company, as defined by the Plan Administrator, to take such further action as it
determines necessary or advisable, and fair and equitable to Participants, with
respect to Awards (other than Options granted pursuant to Section 9 of the
Plan). Such authorized action may include (but shall not be limited to)
establishing. amending or waiving the type, terms, conditions or duration of, or
restrictions on, Awards so as to provide for earlier, later, extended or
additional time for exercise, alternate forms and amounts of payments and other
modifications, and the Plan Administrator may take such actions with respect to
all Participants, to certain categories of Participants or only to individual
Participants. The Plan Administrator may take such actions before or after
granting Awards to which the action relates and before or after any public
announcement with respect to such

                                      -13-
<PAGE>   19
sale, merger, consolidation, reorganization, liquidation or change in control
that is the reason for such action.

12.4     LIMITATIONS

         The grant of Awards will in no way affect the Company's right to
adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

                        SECTION 13. WITHHOLDING OF TAXES

         The Company may require the Holder to pay to the Company the amount of
any withholding taxes that the Company is required to withhold with respect to
the grant or exercise of any Award.

             SECTION 14. AMENDMENT AND TERMINATION OF PLAN

14.1     AMENDMENT OF PLAN

         The Plan may be amended by the shareholders of the Company. The Board
may also amend the Plan in such respects as it shall deem advisable; however, to
the extent required for compliance with Rule 16b-3 under the Exchange Act,
Section 422 of the Code or any applicable law or regulation, shareholder
approval will be required for any amendment that will (i) increase the total
number of shares as to which Awards may be granted under the Plan, (ii)
materially modify the class of persons eligible to receive Awards, (iii)
materially increase the benefits accruing to Participants under the Plan, or
(iv) otherwise require shareholder approval under any applicable law or
regulation. Notwithstanding the foregoing, to the extent required for compliance
with Rule 16b-3 under the Exchange Act or any applicable law or regulation, no
amendment with respect to Section 9 of the Plan shall be made more than once
every six months that would change the amount, price, timing or vesting of the
Options, other than to comport to the changes in the Code, or the rules and
regulations promulgated thereunder.

14.2     TERMINATION OF THE PLAN

         The Company's shareholders or the Board may suspend or terminate the
Plan at any time. The Plan will have no fixed expiration date; provided,
however, that no Incentive Stock Options may be granted more than 10 years after
the Plan's effective date.

14.3     CONSENT OF HOLDER

         The amendment or termination of the Plan shall not, without the consent
of the Holder of any Award under the Plan, alter or impair any rights or
obligations under any Award theretofore granted under the Plan.

                                      -14-
<PAGE>   20
                               SECTION 15. GENERAL

15.1     NOTIFICATION

         The Plan Administrator shall promptly notify a Participant OF an Award,
and a written grant shall promptly be executed and delivered by or on behalf of
the Company.

15.2     CONTINUED EMPLOYMENT OR SERVICES; RIGHTS IN AWARDS

         Neither the Plan, participation in the Plan as a Participant nor any
action of the Plan Administrator taken under the Plan shall be construed as
giving any Participant, including any employee, officer or director of the
Company any right to be retained in the employ of the Company or to continue
service as an officer or director of the Company, or limit the Company's right
to terminate the employment or services of the Participant.

15.3     REGISTRATION; CERTIFICATES FOR SHARES

         The Company shall be under no obligation to any Participant to register
for offering or resale under the Securities Act of 1933, as amended, or register
or qualify under state securities laws, any shares of Common Stock issued under
the Plan. The Company may issue certificates for shares with such legends and
subject to such restrictions on transfer and stop-transfer instructions as
counsel for the Company deems necessary or desirable for compliance by the
Company with federal and state securities laws.

15.4     NO RIGHTS AS A SHAREHOLDER

         No Award shall entitle the Holder to any dividend, voting or other
right of a shareholder unless and until the date of issuance under the Plan of
the shares that are the subject of such Awards, free of all applicable
restrictions.

15.5     COMPLIANCE WITH LAWS AND REGULATIONS

         It is the Company's intention that, so long as any of the Company's
equity securities are registered pursuant to Section 12(b) or 12(g) of the
Exchange Act, the Plan shall comply in all respects with Rule 16b-3 under the
Exchange Act and, if any Plan provision is later found not to be in compliance
with such Rule, the provision shall be deemed null and void, and in all events
the Plan shall be construed in favor of its meeting the requirements of Rule
16b-3. Notwithstanding anything in the Plan to the contrary, the Board, in its
sole discretion, may bifurcate the Plan so as to restrict, limit or condition
the use of any provision of the Plan to Participants who are officers or
directors subject to Section 16 of the Exchange Act without so restricting,
limiting or conditioning the Plan with respect to other Participants.
Additionally, in interpreting and applying the provisions of the Plan, any
Option granted as an Incentive Stock Option pursuant to the Plan shall, to the
extent permitted by law, be construed as an "incentive stock option" within the
meaning of Section 422 of the Code.

                                      -15-
<PAGE>   21
15.6     SEVERABILITY

         If any provision of the Plan or any Award is determined to be invalid,
illegal or unenforceable in any jurisdiction, or as to any person, or would
disqualify the Plan or any Award under any law deemed applicable by the Plan
Administrator, such provision shall be construed or deemed amended to conform to
applicable laws, or, if it cannot be so construed or deemed amended without, in
the Plan Administrator's determination, materially altering the intent of the
Plan or the Award, such provision shall be stricken as to such jurisdiction,
person or Award, and the remainder of the Plan and any such Award shall remain
in full force and effect.

                      SECTION 16. EFFECTIVE DATE

         The Plan's effective date is the date on which it is adopted by the
Board, so long as it is approved by the Company's shareholders at any time
within 12 months of such adoption or, if earlier, and to the extent required for
compliance with Rule 16b-3 under the Exchange Act, at the next annual meeting of
the Company's shareholders after adoption of the Plan by the Board.

                             INTERPOINT CORPORATION

                                    AMENDED

                                      1985

                          INCENTIVE STOCK OPTION PLAN

         The following Incentive Stock Option Plan ("Plan") was adopted by
INTERPOlNT CORPORATION ("Company") effective December 18, 1985, and was approved
by the Shareholders on February 15, 1986. The Plan is intended to qualify under
Section 422A of the Internal Revenue Code of 1954 ("IRC") as finally adopted.
This Plan was amended by amendments adopted by the Board of Directors on
November 4, 1987. In addition, this plan was amended by the Board of Directors
effective December 20, 1989 and approved by affirmative vote of the Shareholders
on February 26, 1990. The Plan was further amended by the Board of Directors
effective December 16, 1992, and approved by affirmative vote of the
Shareholders on February 24, 1993. On November 22, 1993, the Board of Directors
adopted an amendment to the Plan which was approved by affirmative vote of the
Shareholders on February 11, 1994. Finally, the Plan was amended by the Board of
Directors effective December 7, 1994 and approved by affirmative vote of the
Shareholders on February 22, 1995.


1.       PURPOSE.

         The purpose of the Plan is to provide for the issuance of options to
key salaried employees ("Team Members") to purchase shares of the Company's
authorized but unissued common stock without par value in order to encourage key
salaried Team Members to have a proprietary interest in successful operations of
the Company and to expand and improve the Company's profits.

2.       SHARES UNDER PLAN.

         The aggregate number of shares which may be issued under the Plan
through amendment is 490,000 shares.


3.       ELIGIBILITY.

         a.       To be eligible to receive an option under the Plan, an
individual must on the date of granting the option be a salaried Team Member of
either the Company, a parent or subsidiary of the Company, or a corporation or a
parent or subsidiary corporation of such
<PAGE>   23
corporation issuing or assuming a stock option in a transaction to which IRC
Section 425(a) applies.

         b.       No individual may receive grant of an option who at the time
the option is granted owns stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the employer corporation
or of its parent or subsidiary corporation unless at the time the option is
granted the option price is at least 110 percent of the fair market value of the
stock subject to the option and the option by its terms is not exercisable after
the expiration of five years from the date that option is granted.

4.       ADMINISTRATION.

         The Plan will be administered by a Committee of the Board of Directors
of the Company ("Committee") consisting of outside Directors (those who are not
employees of the Company). The Committee is authorized, consistent with the
Plan: to select Team Members to whom options are granted, to fix the number of
shares and price per share granted to each, to determine whether payable in
money or in stock of the Company or otherwise, to fix the date of grant, date of
termination and expiration and terms and conditions of each option, to interpret
the Plan, to determine rights and obligations of option holders, to grant
options and direct the Company to execute option agreements, to perform all
other acts necessary or convenient to administer the Plan, and to correct any
defect, omission or inconsistency in the Plan necessary to effect its purpose
and qualify as an incentive stock option plan under the IRC Section 422A. In
addition, the Interpoint President, or others as he or she may assign, may grant
options to newly hired Team Members who are not executive officers.

5.       TERMS OF OPTIONS.

         Each option must comply with the following terms:

         a.       Grant. The option must be granted within ten years from the
date the Plan is adopted or the date the Plan is approved by the shareholders,
whichever is earlier.

         b.       Option Price. The option price must not be less than the fair
market value of the stock at the time the option is granted. The fair market
value shall be the closing market price on the last business day preceding the
date of grant, or, if no trades were made on that day, it shall be the mean
between the bid and ask prices quoted by NASDAQ at the close of the market on
that day.

         c.       Exercise. Subject to the next two sentences, the option may be
exercisable for all or part of the shares subject to the option and at any
intervals determined by the Committee. No option may be exercisable after the
first to occur of the following events:

                  (1)      The expiration of ten years from the date the option
is granted or such shorter period as the Committee may determine for that
option, and

                                       -2-
<PAGE>   24
                  (2)      The expiration of three months from the date the
option holder ceases to be employed by the employer corporation, or the
expiration of one year from the date the option holder ceases to be employed by
the employer corporation in the case of a Team Member who dies or is disabled
within the meaning of IRC Section 22(c)(3).

         Each option must be exercised by written notice to the Company signed
by the option holder or his or her personal representative stating the number of
shares being purchased and accompanied by full payment.

         d.       Sequential Exercise -- Pre-1987 Options. No option which was
granted prior to January 1, 1987 may be exercised while there is outstanding
(meaning not exercised in full or not expired by reason of lapse of time) any
incentive stock option which was granted, before the granting of the pre-1987
option, to the individual to purchase stock in the individual's employer
corporation or in a corporation which (at the time of the granting of the
option) is a parent or subsidiary corporation of the employer corporation, or in
a predecessor corporation of any such corporations.

         e.       Non-transferability. The option may not be transferable by the
individual to whom granted otherwise than by will or the laws of descent and
distribution, and must be exercisable, during the individual's lifetime, only by
the individual.

         f.       Payment. If approved by the Committee, the price for the stock
issued upon exercise of the option may be paid in stock of the corporation
granting the option.

         g.       Lapse. Upon lapse of any option not exercised in full, the
unexercised shares will become available for other option under the Plan.

6.       OPTION AGREEMENT.

         Each option granted under the Plan will be evidenced by a written
agreement executed by the Company and the option holder, and will contain terms
and conditions as the Committee deems desirable not inconsistent with the Plan.

7.       NON-QUALIFIED OPTIONS.

         Unless the option agreement provides otherwise, options granted under
the Plan are intended to be incentive stock options qualifying under IRC Section
422A, as amended. Non-qualified stock options may be granted under this Plan if
the option agreement granting the option states that it is intended that the
option not qualify as an incentive stock option. Paragraphs 3.b. and 5.d. of
this Plan shall not apply to non-qualified options granted hereunder.

8.       CHANGE IN CAPITALIZATION.

         If the Company changes its capitalization, whether by stock dividend,
stock split-up, reclassification or recapitalization, merger or consolidation,
or otherwise (if the option does 

                                       -3-
<PAGE>   25
not terminate pursuant to paragraph 9), then the number and kind of shares then
subject to options and thereafter to become subject to options and the prices to
be paid therefor, will be proportionately adjusted by the Committee to whatever
extent the Committee determines the change equitably requires an adjustment,
without issuance of any fractional option or share.

9.       MERGER OR CONSOLIDATION.

         If the Company dissolves, is reorganized, splits up its stock or merges
or consolidates with any other corporation and the Company is not the surviving
corporation, then (unless one or more of the surviving corporations assumes the
options under the Plan or issues substitute options) each holder of outstanding
options will be notified of and have the right to exercise the options prior to
the dissolution, reorganization, stock split-up, merger or consolidation. Any
option not exercised within thirty (30) days of notification will thereupon
terminate, and simultaneously the Plan will terminate.

10.      OPTIONS TO OUTSIDE DIRECTORS.

         Notwithstanding any provision in this Plan to the contrary, options to
outside Directors shall be non-qualified options and shall be granted only in
accordance with the following provisions:

         a.       Grant. Each outside Director, upon his or her first election
or appointment as a director of the Company, shall be granted a non-qualified
option for 5,500 shares and shall not be eligible for any other options under
this or any other option plan of the Company.

         b.       Vesting. Each option granted under this Section 10 shall vest
as follows: options for 1,375 shares shall be exercisable on and after one (1)

exercisable on end after each of the three succeeding anniversaries of the date
of grant.

         c.       Availability of Shares. The options provided for in this
Section 10 are subject to the availability of shares under this Plan. If at the
date of any grant there are insufficient shares available to satisfy the grants
in whole, then the shares available shall be divided by the number of outside
Directors then entitled to a grant and each such outside Director shall be
granted an option for that number of shares.

         d.       Term of Option. The term of each option shall be for a period
of ten (10) years from the date of grant thereof.

         e.       Option Price. The option price must not be less than the fair
market value of the stock at the time the option is granted. The fair market
value shall be the closing market price on the last business day preceding the
date of grant, or, if no trades were made on that day, it shall be the mean
between the bid and ask prices quoted by NASDAQ at the close of the market on
that day.

                                       -4-
<PAGE>   26
         f.       Other Terms Applicable. Except as otherwise provided in this
Section 10, options granted to outside Directors shall be subject to the terms
and conditions of this Plan applicable to other option holders.

         c.       extend the term for which options may be granted;

         d.       change the class of employees eligible to receive options; or

         e.       cause any condition or provision of an option or the Plan to
be inconsistent with the provisions of IRC Section 422A(b).


12.      TERMINATION OF PLAN.

         The Plan will terminate on December 17, 1995, except that the Board of
Directors of the company may terminate the Plan sooner at any time. No
termination, other than as provided in paragraph 9, will affect any option then
outstanding.

13.      SEVERABILITY.

         If any provision of this Plan or of any option is determined to be
inconsistent with the provisions of IRC Section 422A, the inconsistent provision
will be deemed omitted and the remaining provisions will remain in effect.

9.       VESTING AND EXERCISE OF OPTION.

         Options shall be 100 percent vested immediately upon grant unless the
Committee establishes another vesting schedule.

         Options shall be exercisable at any time after vesting (but no later
than ten (10) years after the option is granted), subject, however, to all other
terms of the Plan and of the Option granted to an Optionee. An Option may not be
exercised for fractional Shares of the Shares of the Company.

         Notwithstanding the foregoing, in the event the Company or the
shareholders of the Company enter into an agreement to dispose of all or
substantially all of the assets or shares by means of a sale, a reorganization,
a liquidation, or otherwise, Options shall become immediately exercisable with
respect to the full number of Shares subject to those Options. All Options not
exercised prior to consummation of any such agreement shall terminate.

         a.       Procedure for Exercise. An Option shall be deemed to be
exercised when written notice of such exercise has been given to the Company in
accordance with the terms and full payment for the Shares with respect to which
the Option is exercised has been received by the Company. Until the issuance of
the stock certificates (as evidenced by the

                                       -3-
<PAGE>   30
appropriate entry on the books of the Company), no right to vote or receive
dividends or any other rights as a stockholder shall exist with respect to
Optioned Shares notwithstanding the exercise of the Option. No adjustment will
be made for a dividend or other rights for which the record date is prior to the
date of exercise of the Option except as provided in Section 13 of the Plan.

         b.       Time of Exercise, Effect of Termination. Unless otherwise
provided in the terms of an Option, it is the intent of this Plan that an Option
may be exercised by the Optionee as provided in this Plan only while he or she
has a relationship with the Company as described herein, except as set out
below. If the Optionee's relationship is terminated, the following rules
control:

                  (1)      If the Optionee dies, the persons to whom the
Optionee's rights have passed by will or the laws of descent and distribution
may exercise such rights, to the extent the Optionee could have done so,
immediately preceding his death. Any such Option must be exercised within twelve
(12) months of the Optionee's death, but in no event later than ten (10) years
after its grant.

                  (2)      If the Optionee's relationship with the Company is
terminated, due to his or her embezzlement or theft of Company funds,
defraudation of the Company, violation of Company rules, regulations or
policies, or any intentional act which harms the Company, such Option, to the
extent not exercised as of the date of termination, shall be terminated as of
that date.

                  (3)      If the Optionee's relationship with the Company is
terminated, for any reason other than those set forth in subparagraphs (1) and
(2) above, the Optionee may exercise his Option, to the extent exercisable as of
the date of his termination, within sixty (60) days after termination, but in no
event later than ten (10) years after its grant.

10.      OPTION NOT TRANSFERABLE.

         Options under the Plan may not be sold, pledged, assigned or
transferred in any manner other than by will or the laws of descent and
distribution, and may be exercised during the Optionee's lifetime only by the
Optionee, or his guardian or legal representative.

11.      OPTIONS TO OUTSIDE DIRECTORS.

         Notwithstanding any provision in this Plan to the contrary, Options to
Outside Directors shall be granted only in accordance with the following
provisions:

         a.       Grant. Each Outside Director shall be granted an Option for
5,500 Shares upon the later of (i) the adoption of this Amended Non- Qualified
Stock Option Plan by the Shareholders or (ii) his or her initial election or
appointment as a director of the Company, and shall not be eligible for any
other Options under this Plan.

                                       -4-
<PAGE>   31
         b.       Vesting. Each Option granted under this Section 11 shall vest
as follows: options for 1,375 Shares shall be exercisable on and after one (1)
year from the date of grant, and options for an additional 1,375 Shares shall be
exercisable on and after each of the three succeeding anniversaries of the date
of grant.

         c.       Availability of Shares. The Options provided for in this
Section 11 are subject to the availability of shares under this Plan. If at the
date of any grant there are insufficient Shares available to satisfy the grants
in whole, then the Shares available shall be divided by the number of Outside
Directors then entitled to a grant and each such Outside Director shall be
granted an Option for that number of Shares.

         d.       Term of Option. The term of each Option shall be for a period
of ten (10) years from the date of grant thereof.

         e.       Option Price. The Option price shall be the fair market value
of the Shares at the time the option is granted. This shall be the mean between
the bid and ask prices for Shares of the Common Stock quoted by NASDAQ as of the
close of the last business day immediately preceding the date of grant.

         f.       Other Terms Applicable. Except as otherwise provided in this
Section 11, Options granted to Outside Directors shall be subject to the terms
and conditions of this Plan applicable to other optionees.

12.      AMENDMENT OR TERMINATION OF THE PLAN.

         a.       The Board may amend the Plan from time to time in such
respects as the Board deems advisable, except that no amendment may, without
further stockholder approval or ratification:

                  (1)      Increase the total number of Shares which may be
purchased under Section 3 of the Plan (subject, however, to Section 13);

                  (2)      Change the definition of eligibility in Section 5 of
the Plan;

                  (3)      Change the term of Option stated in Section 7 of the
Plan.

         b.       The Board, without further approval of the stockholders, may
at any time terminate the Plan.

         c.       Any Amendment or Termination of the Plan shall not affect
Options already granted and such Options shall remain in full force and effect
as if the Plan had not been amended or terminated.

13.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

         The number and kind of Shares of Company stock subject to Option, in
respect thereof, shall be appropriately adjusted along with a corresponding
adjustment in the Option 

                                       -5-
<PAGE>   32
price to reflect any stock dividend, stock split, split-up or any combination or
exchange of Shares, however accomplished. An appropriate adjustment shall also
be made with respect to the aggregate number and kind of Shares remaining
available to be optioned and sold under the Plan.

14.      AGREEMENT AND REPRESENTATION OF EMPLOYEE.

         As a condition to the exercise of any portion of an Option, the Company
may require the person exercising such Option to represent and warrant at the
time of exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute the Shares if, in the
opinion of counsel for the Company, such a representation is required under the
Securities Act of 1933 or any other applicable law, regulation or rule of any
governmental agency.

15.      RESERVATIONS OF SHARES OF COMMON STOCK.

         The Company, during the term of this Plan, will at all times reserve
and keep available, and will seek or obtain from any regulatory body having
jurisdiction any requisite authority in order to issue and sell, such number of
Shares as shall be sufficient to satisfy the requirements of the Plan. Inability
of the Company to obtain from any regulatory body having jurisdiction authority
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder shall relieve the Company of any liability in respect of
the non-issuance or sale of Shares as to which such requisite authority shall
not have been obtained.

                           INCENTIVE STOCK OPTION PLAN


         The following Incentive Stock Option Plan ("Plan") is adopted by
INTERPOINT CORPORATION ("Company") effective December 1, 1981, if approved by
affirmative vote of the holders of a majority of the Company's shares within
twelve months after December 1, 1981, the date of adoption by the Board of
Directors. The Plan is intended to qualify under Section 422A of the Internal
Revenue Code of 1954 ("IRC") as finally adopted. This Plan was amended by
amendments adopted by the Board of Directors on November 4, 1987 and October 17,
1990.

1.       PURPOSE.

         The purpose of the Plan is to provide for the issuance of options to
key salaried employees to purchase shares of the Company's authorized but
unissued common stock without par value in order to encourage key salaried
employees to have a proprietary interest in successful operations of the Company
and to expand and improve the Company's profits.

2.       SHARES UNDER PLAN.

         The aggregate number of shares which may be issued under the Plan is
25,000 shares.

3.       ELIGIBILITY.

         a.       To be eligible to receive an option under the Plan, an
individual must on the date of granting the option be a salaried employee of
either the Company, a parent or subsidiary of the Company, or a corporation or a
parent or subsidiary corporation of such corporation issuing or assuming a stock
option in a transaction to which IRC Section 425(a) applies.

         b.       No individual may receive grant of an option who at the time
the option is granted owns stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the employer corporation
or of its parent or subsidiary corporation unless at the time the option is
granted the option price is at least 110 percent of
<PAGE>   34
the fair market value of the stock subject to the option and the option by its
terms is not exercisable after the expiration of five years from the date that
option is granted.

4.       ADMINISTRATION.

         The Plan will be administered by a Committee of the board of Directors
of the Company ("Committee"). The Committee is authorized, consistent with the
Plan: to select employees to whom options are granted, to fix the number of
shares and price per share granted to each, to determine whether payable in
money or in stock of the Company or otherwise, to fix the date of grant, date of
termination and expiration and terms and conditions of each option, to interpret
the Plan, to establish, change and rescind rules for the Plan, to determine
rights and obligations of option holders, to grant options and direct the
Company to execute option agreements, to perform all other acts necessary or
convenient to administer the Plan, and to correct any defect, omission or
inconsistency in the Plan necessary to effect its purpose and qualify as an
incentive stock option plan under the IRC Section 422A.

5.       TERMS OF OPTIONS.

         Each option must comply with the following terms.

         a.       Grant. The option must be granted within ten years from the
date the Plan is adopted or the date the Plan is approved by the shareholders,
whichever is earlier.

         b.       Option Price. The option price must not be less than the fair
market value of the stock at the time the option is granted, which may be the
mean between the bid and ask prices quoted in the Seattle Times as of the close
of the last business day immediately preceding the date of grant.

         c.       Exercise. Subject to the next two sentences, the option may be
exercisable for all or part of the shares subject to the option and at any
intervals determined by the Committee. No option may be exercisable after the
first to occur of the following events:

                  (1)      The expiration of ten years from the date the option
is granted or such shorter period as the Committee may determine for that
option, and

                  (2)      the expiration of three months from the date the
option holder ceases to be employed by the employer corporation, or the
expiration of one year from the date the option holder ceases to be employed by
the employer corporation in the case of an employee who dies or is disabled
within the meaning of IRC Section 22(c)(3).

by the option holder or his or her personal representative stating the number of
shares being purchased and accompanied by full payment.

         d.       Sequential Exercise -- Pre-1987 Options. No option which was
granted prior to January 1, 1987 may be exercised while there is outstanding
(meaning not exercised in full or not expired by reason of lapse of time) any
incentive stock option which was granted, before the granting of the pre-1987
option, to the individual to purchase stock in the individual's employer
corporation or in a corporation which (at the time of the granting of the
option) is a parent or subsidiary corporation of the employer corporation, or in
a predecessor corporation of any of such corporations.

         e.       Nontransferability. The option may not be transferable by the
individual to whom granted otherwise than by will or the laws of descent and
distribution, and must be exercisable, during the individual's lifetime, only by
the individual.

         f.       Payment. If approved by the Committee, the price for the stock
issued upon exercise of the option may be paid in stock of the corporation
granting the option.

         g.       Lapse. Upon lapse of any option not exercised in full, the
unexercised shares will become available for other options under the Plan.

6.       OPTION AGREEMENT.

         Each option granted under the Plan will be evidenced by a written
agreement executed by the Company and the option holder, and will contain terms
and conditions as the Committee deems desirable not inconsistent with the Plan.

7.       NON-QUALIFIED OPTIONS.

         Unless the option agreement provides otherwise, options granted under
this Plan are intended to be incentive stock options qualifying under IRC
Section 422A, as amended. Non-qualified stock opTions may be granted under this
Plan if the option agreement granting the option states that it is intended that
the option not qualify as an incentive stock option. Paragraphs 3.b. and 5.d. of
this Plan shall not apply to non-qualified options granted hereunder.

8.       CHANGES IN CAPITALIZATION.

         If the Company changes its capitalization, whether by stock dividend,
stock split-up, reclassification or recapitalization, merger or consolidation,
or otherwise, (if the option does not terminate pursuant to paragraph 9) then
the number and kind of shares then subject to options and thereafter to become
subject to options and the prices to be paid therefor, will be proportionately
adjusted by the Committee to whatever extent the Committee determines the change
equitably requires an adjustment, without issuance of any fractional option or
share.

9.       MERGER OR CONSOLIDATION.

         If the Company dissolves, is reorganized, splits up its stock or merges
or consolidates with any other corporation and the Company is not the surviving
corporation, then (unless one or more of the surviving corporations assumes the
options under the Plan or issues substitute options) each holder of outstanding
options will be notified of and have the right to exercise the options prior to
the dissolution, reorganization, stock split-up, merger or consolidation. Any
option not exercised within thirty (30) days of notification will thereupon
terminate, and simultaneously the Plan will terminate.

10.      AMENDMENT OF PLAN.

         The Board of Directors of the Company may amend the Plan and, with the
consent of each option holder affected, the terms and conditions of granted
options as it deems advisable, but may not without the approval of the holders
of not less than a majority of the outstanding capital stock of the Company:

         a.       increase the maximum number of shares subject to the Plan,
except pursuant to paragraph 8;

         b.       decrease the option price provided for in paragraph 5;

         c.       extend the term for which options may be granted;

         d.       change the class of employees eligible to receive options; or

         e.       cause any condition or provision of an option or the Plan to
be inconsistent with the provisions of IRC Section 422A(b).

11.      TERMINATION OF PLAN.

         The Plan will terminate on November 30, 1991, except that the Board of
Directors of the Company may terminate the Plan sooner at any time. No
termination, other than as provided in paragraph 9 will affect any option then
outstanding.

12.      SEVERABILITY.

         If any provision of this Plan or of any option is determined to be
inconsistent with the provisions of IRC Section 422A, the inconsistent provision
will be deemed omitted and the remaining provisions will remain in effect.
