Offer to Exchange Certain Outstanding Options for New Options
(the "Offer to Exchange")

The offer and withdrawal rights expire at 9:00 p.m., Pacific Standard Time
on December 17, 2001, unless the offer is extended.

Pinnacle Systems, Inc. ("Pinnacle") is offering eligible employees the
opportunity to exchange certain outstanding options to purchase shares of
Pinnacle common stock for new options. We are making the offer upon the terms
and conditions described in (i) this Offer to Exchange Certain Outstanding
Option for New Options (the "Offer to Exchange"); (ii) the related Memorandum
from Xxxx X. Xxxxxxx dated November 16, 2001; (iii) the Election Form; and (iv)
the Notice to Withdraw from the Offer (which together, as they may be amended
from time to time, constitute the "offer" or "program").

The number of shares subject to the new options to be granted to each
eligible employee will be equal to the number of shares subject to the options
tendered by the eligible employee and accepted for exchange. Subject to the
terms and conditions of this offer, we will grant the new options on the first
business day which is at least six (6) months and one (1) day after the date we
cancel the options accepted for exchange. You may only tender options for all or
none of the outstanding, unexercised shares subject to an individual option
grant. All tendered options accepted by us through the offer will be cancelled
promptly after 9:00 p.m. Pacific Standard Time on the date the offer ends. The
offer is currently scheduled to expire on December 17, 2001 at 9:00 p.m. Pacific
Standard Time (the "Expiration Date") and we expect to cancel options on
December 18, 2001, which is the first business day following the Expiration
Date, unless the proposed cancellation date is extended as described in Section
19 of this Offer to Exchange (the "Cancellation Date"). If you elect to exchange
any of your options, all options granted to you in the six (6) months prior to
the commencement of the offer will also be cancelled and replaced by new
options, provided that you are still employed by Pinnacle or a successor entity
on the date the new options are granted. Since the offer commenced on November
16, 2001, this means that if you participate in the offer, you will be required
to tender all options granted to you since May 16, 2001, including any options
granted between the date the offer commences and the Cancellation Date.

The offer is not conditioned on a minimum number of options being tendered.
Participation in the offer is completely voluntary. The offer is subject to
conditions that we describe in Section 7 of this Offer to Exchange.

You may participate in the offer if you are an employee of Pinnacle or one
of our subsidiaries who resides or works in the United States, France, Germany,
Japan or the United Kingdom; however, directors and employees who are defined as
"officers" for purposes of Section 16(b) of the Exchange Act of 1934, as
amended, and who are listed on Schedule A-1 to this Offer to Exchange, are not
eligible to participate in this offer. In order to receive a new option pursuant
to this offer, you must continue to be an employee as of the date on which the
new options are granted, which will be at least six (6) months and one (1) day
after the Cancellation Date.

If you tender options for exchange as described in the offer, and we accept
your tendered options, then, subject to the terms of this offer, we will grant
you new options under the same stock option plan under which your tendered
options were issued. For example, if you tender options that were issued under
the Pinnacle 1996 Stock Option Plan, as amended, (the "1996 Plan"), your new
options will be issued under the 1996 Plan.

The exercise price per share of the new options will be 100% of the fair
market value of Pinnacle's common stock on the date of grant of the new options,
as determined by the closing price of Pinnacle's common stock reported by the
Nasdaq National Market on the date of grant. If, however, prior to the date of
grant of the new options Pinnacle enters into a merger or stock acquisition
whereby Pinnacle is acquired by another company, then the new stock options you
receive could be for the purchase of the acquiror's stock (as opposed to
Pinnacle's), with an exercise price equal to the fair market value of such
acquiror's stock on the date the new option is granted. Even upon the happening
of such events, the date the new option is granted will remain a date which is
at least six (6) months and one (1) day after the Cancellation Date. We expect
the date of grant of the new options to be June 19, 2002.

Each new option will be exercisable for the same number of shares as were
exercisable under the tendered options immediately before they were cancelled on
the Cancellation Date. Upon the happening of a merger or stock acquisition
whereby Pinnacle is acquired by another company, the number of shares subject to
your new option would be adjusted so that the number of shares you receive would
be equal to the number of our shares that were accepted for exchange, multiplied
by the exchange ratio that was used in the merger or acquisition.

The vesting start date for each new option will be the date that the new
options are granted. The new options will, subject to your continued employment
with Pinnacle on the date the new options are granted, vest according to the
following schedule:

. 1/3 of the shares subject to the new option will vest immediately on
the date that the new option is granted; and

. the remainder of the shares subject to the new option will vest
monthly over the twenty-four (24) months following the date that the
new options are granted (at least six (6) months and one (1) day from
the Cancellation Date.)

You will not receive any vesting credit for any time prior to the date that the
new options are granted, even if the old options that you tender for exchange
are vested, in whole or in part, on the Cancellation Date or would have vested,
in whole or in part, during the six (6) month and one (1) day period following
the Cancellation Date. As a result, you will not be able to purchase common
stock pursuant to your new options as early as you would have been able to
purchase common stock under your old options, had you not tendered your old
options for exchange. For example:

. An employee cancels an option to purchase 3,600 shares that is 1/2
vested at the time of cancellation.

. The new option grant occurs six (6) months and one (1) day after the
cancellation.

-2-

. The new option will be 1/3rd vested at the time of grant, so the
employee is vested as to 1,200 of the shares subject to the new option
(which is 1/3rd of 3,600).

. The new option will vest as to an additional 100 shares (which is
1/24th of the 2,400 remaining shares) subject to the new option for
each of the following 24 months, at which time the new option will be
100% vested.

Although our Board of Directors has approved the offer, neither we nor our
Board of Directors make any recommendation as to whether you should tender or
not tender your options for exchange. You must make your own decision whether or
not to tender your options.

Shares of Pinnacle common stock are traded on the Nasdaq National Market
under the symbol "PCLE." On November 9, 2001, the closing price of our common
stock reported on the Nasdaq National Market was $4.30 per share.

We recommend that you evaluate current market quotes for our common stock,
among other factors, before deciding whether or not to tender your options.

This Offer to Exchange has not been approved or disapproved by the
Securities and Exchange Commission (the "SEC") or any state securities
commission nor has the SEC or any state securities commission passed upon the
accuracy or adequacy of the information contained in this Offer to Exchange. Any
representation to the contrary is a criminal offense.

You should direct questions about the offer or requests for assistance or
for additional copies of this Offer to Exchange, the memorandum from Xxxx X.
Xxxxxxx dated November 16, 2001, the Election Form and the Notice to Withdraw
from the Offer, to Xxxxxxx Xxxxx at Pinnacle Systems, Inc., 000 Xxxxx Xxxxxxxx

the Election Form in accordance with its instructions, and fax or hand deliver
it and any other required documents to Xxxxxxx Xxxxx at fax number (650)
000-0000 on or before 9:00 p.m. Pacific Standard Time on December 17, 2001.

We are not making the offer to, and we will not accept any tender of
options from or on behalf of, option holders in any jurisdiction in which the
offer or the acceptance of any tender of options would not be in compliance with
the laws of that jurisdiction. However, we may, at our discretion, take any
actions necessary for us to make the offer to option holders in any of these
jurisdictions.

as to whether you should tender or not tender your options through the offer.

referred you. We have not authorized anyone to give you any information or to

SUMMARY TERM SHEET

The following are answers to some of the questions that you may have about
the offer. We urge you to read carefully the remainder of this Offer to
Exchange, the accompanying Memorandum from Xxxx X. Xxxxxxx dated November 16,
2001, the Election Form and the Notice to Withdraw from the Offer because the
information in this summary is not complete, and additional important
information is contained in the remainder of this Offer to Exchange, the
accompanying Memorandum from Xxxx X. Xxxxxxx dated November 16, 2001, the
Election Form and the Notice to Withdraw from the Offer. We have included page
references to the remainder of this Offer to Exchange where you can find a more
complete description of the topics in this summary.

1. What securities is Pinnacle offering to exchange?

We are offering to exchange all outstanding, unexercised options to
purchase shares of common stock of Pinnacle issued under the 1996 Plan and the
1996 Supplemental Stock Option Plan, as amended, (the "1996 Supplemental Plan")
that are held by eligible employees, in return for new options that we will
grant under the same Pinnacle stock option plan pursuant to which the cancelled
option which it replaces was granted. If you participate in the offer, you must
tender all options received since May 16, 2001, including any options granted
between the date the offer commences and the date the options are cancelled.
(Page 15)

2. Who is eligible to participate?

Employees are eligible to participate if they are employees of Pinnacle or
one of Pinnacle's subsidiaries as of the date the offer commences and remain
employees of Pinnacle or one of Pinnacle's subsidiaries through the date on
which the tendered options are cancelled, but only if they live or work in the
United States, France, Germany, Japan or the United Kingdom; however, members of
the Board of Directors and all employees who are defined as "officers" for
purposes of Section 16(b) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), (as listed on Schedule A-1 to this Offer to Exchange) are
not eligible to participate. In order to receive a new option, you must remain
an employee of Pinnacle as of the date the new options are granted, which will
be at least six (6) months and one (1) day after the Cancellation Date. If
Pinnacle does not extend the offer, the new options will be granted on June 19,
2002. (Page 17)

3. Are employees outside the United States eligible to participate?

Yes. Employees who live or work in Germany, France, Japan and the United
Kingdom are also eligible to participate.

4. Why is Pinnacle making the offer?

We believe that granting stock options motivates high levels of performance
and provides an effective means of recognizing employee contributions to the
success of our company. The offer provides an opportunity for us to offer
eligible employees a valuable incentive to stay with our company. Some of our
outstanding options, whether or not they are currently exercisable, have
exercise prices that are significantly higher than the current market price of
our shares. We believe

these options are unlikely to be exercised in the foreseeable future. By making
this offer to exchange outstanding options for new options that will have an
exercise price equal to the market value of the underlying shares on the grant
date, we intend to provide our eligible employees with the benefit of owning
options that over time may have a greater potential to increase in value, create
better performance incentives for eligible employees and thereby maximize
shareholder value. (Page 18)

5. What are the conditions to the offer?

The offer is not conditioned on a minimum number of options being tendered.
Participation in the offer is completely voluntary. The conditions are described
in Section 7 of this Offer to Exchange. (Page 23)

6. Are there any eligibility requirements that I must satisfy after the
expiration date of the offer to receive the new options?

To receive a grant of new options through the offer and under the terms of
the particular Pinnacle stock option plan pursuant to which your old options
were granted, you must be employed by Pinnacle or one of its subsidiaries as of
the date the new options are granted.

As discussed below, subject to the terms of this offer, we will grant the
new options on the first business day which is at least six (6) months and one
(1) day after the date we cancel the options accepted for exchange. We expect
that we will grant the new options on June 19, 2002. If, for any reason, you do
not remain an employee of Pinnacle or one of its subsidiaries through the date
we grant the new options, you will not receive any new options or other
consideration in exchange for your tendered options that have been accepted for
exchange and subsequently cancelled. You are reminded that unless expressly
provided in your employment agreement, your employment with Pinnacle remains "at
will" and can be terminated by you or Pinnacle at any time, with or without
cause or notice. (Page 23)

7. How many new options will I receive in exchange for my tendered options?

If you meet the eligibility requirements and subject to the terms of this
offer, we will grant you new options to purchase the number of shares equal to
the number of shares subject to the options you tender. If, however, prior to
the date of grant of the new options Pinnacle enters into a merger or stock
acquisition whereby Pinnacle is acquired by another company, then the new stock
options you receive could be for the purchase of the acquiror's stock (as
opposed to Pinnacle's), and the number of shares would be adjusted. For example,
if we were acquired by means of a merger, you would receive the number of shares
underlying options that were accepted for exchange and cancelled, multiplied by
the exchange ratio that was used in the merger. New options will be granted
under the same stock option plan pursuant to which your cancelled options were
granted, unless prevented by law or applicable regulations. All new options will
be subject to new option agreements between you and us. You must execute the new
option agreement before receiving new options. (Page 17)

-2-

8. When will I receive my new options?

We will grant the new options on the first business day which is at least
six (6) months and one (1) day after the date we cancel the options accepted for
exchange (the "New Option Grant Date"). Under no circumstances will we grant the
new options prior to the New Option Grant Date. If we cancel tendered options on
December 18, 2001, which is the scheduled date for the cancellation of the
options (the first business day following the expiration date of the offer), the
new options will be granted on June 19, 2002. You must continue to be an
employee of Pinnacle or one of its subsidiaries on the New Option Grant Date to
be eligible to receive the new options. (Page 21)

9. Why won't I receive my new options immediately after the expiration date of
the offer?

If we were to grant the new options on any date which is earlier than six
(6) months and one (1) day after the date we cancel the options accepted for
exchange, we would be subject to onerous accounting charges. We would be
required for financial reporting purposes to treat the new options as variable
awards. This means that we would be required to record the non-cash accounting
impact of decreases and increases in Pinnacle's stock price as a compensation
expense for the new options issued under this offer. We would have to continue
this variable accounting for these new options until they were exercised,
forfeited or terminated. The higher the market value of our shares, the greater
the compensation expense we would have to record. By deferring the grant of the
new options for at least six (6) months and one (1) day, we believe we will not
have to treat the new options as variable awards.

10. If I tender options in the offer, will I be eligible to receive other option
grants before I receive my new options?

No. If we accept options you tender in the offer, you cannot receive any
other option grants before you receive your new options. We will defer until the
New Option Grant Date the grant of other options, such as annual, bonus or
promotional options, for which you may otherwise be eligible before the New
Option Grant Date. We will defer the grant to you of these other options if we
determine it is necessary for us to do so to avoid incurring compensation
expense against our earnings because of accounting rules that could apply to
these interim option grants as a result of the offer. Instead, we will issue a
promise to grant stock option(s) to you on the date when such grant would no
longer subject us to these onerous accounting charges as a result of the
exchange offer. However, if you are no longer employed at Pinnacle or one of its
subsidiaries on the date of grant of the new options, you will not receive new
options even if a promise to grant stock option(s) has been issued to you. (Page
22)

11. Will I be required to give up all my rights to the cancelled options?

Yes. Once we have accepted for exchange options tendered by you, your
options will be cancelled and you will no longer have any rights under those
options. We intend to cancel all options accepted for exchange on the first
business day following the expiration of the offer. We expect the Cancellation
Date to be December 18, 2001. (Page 21)

-3-

12. What will the exercise price of the new options be?

The exercise price per share of the new options will be 100% of the fair
market value of Pinnacle's common stock on the date of grant, as determined by
the closing price of Pinnacle's common stock reported by the Nasdaq National
Market on the date of grant of the new options.

If, however, prior to the date of grant of the new options Pinnacle enters
into a merger or stock acquisition whereby Pinnacle is acquired by another
company, then the new stock options you receive could be for the purchase of the
acquiror's stock (as opposed to Pinnacle's), with a per share exercise price
equal to the fair market value of such acquiror's stock on the New Option Grant
Date. Regardless of any such merger or stock acquisition, the New Option Grant
Date will be at least six (6) months and one (1) day after the Cancellation
Date.

Accordingly, we cannot predict the exercise price of the new options.
Because we will grant new options on the first business day that is at least six
(6) months and one (1) day after the date we cancel the options accepted for
exchange, the new options may have a higher exercise price than some or all of
your current options. We recommend that you evaluate current market quotes for
our shares, among other factors, before deciding whether or not to tender your
options. (Page 27)

13. When will the new options vest?

The vesting of the newly issued options will be in accordance with the
vesting schedule set forth below.

The vesting start date for each new option will be the date that the new
options are granted. The new options will, subject to your continued employment
with Pinnacle on the date the New Options are granted, vest according to the
following schedule:

. 1/3 of the shares subject to the new option will vest immediately on
the date that the new option is granted; and

. An employee cancels an option to purchase 3,600 shares that is 1/2
vested at the time of cancellation.

-4-

. The new option grant occurs six (6) months and one (1) day after the
cancellation.

. The new option will be 1/3rd vested at the time of grant, so the
employee is vested as to 1,200 of the shares subject to the new option
(which is 1/3rd of 3,600).

14. What if Pinnacle enters into a merger or stock acquisition whereby another
company acquires Pinnacle?

It is possible that, prior to the grant of new options, we might effect or
enter into an agreement such as a merger or stock acquisition whereby another
company acquires Pinnacle. The promise to grant stock option(s) that we will
give you in exchange for your cancelled options is a binding commitment, and any
successor of Pinnacle will honor that commitment.

You should be aware that these types of transactions could have substantial
effects on our stock price, including potentially substantial appreciation in
the price of our shares. Depending on the structure of this type of transaction,
tendering option holders might be deprived of any further price appreciation in
the shares associated with the new options. For example, if our shares were
acquired in a cash merger, the fair market value of our shares, and hence the
price at which we grant the new options, would likely be a price at or near the
cash price being paid for the shares in the transaction, yielding limited or no
financial benefit to a recipient of the new options for that transaction. In
addition, in the event of an acquisition of our company for stock, tendering
option holders might receive options to purchase shares of a different issuer.
Option holders who do not tender in the offer will have their outstanding
options treated in accordance with the terms of the plan they are granted under
and if their options are assumed by the successor to our company, those options
would be priced in accordance with the terms of the transaction. This could
potentially result in a greater financial benefit for those option holders who
opted not to participate in this offer and who instead retained their original
options.

Finally, if another company acquires us, that company may, as part of the
transaction or otherwise, decide to terminate some or all of our employees prior
to the grant of new options under this option exchange program. Termination for
this, or any other, reason before the replacement option is granted means that
you will not receive the replacement option, nor will you receive any other
consideration for the options that were cancelled.

15. Are there circumstances where I would not be granted new options?

Yes. If, for any reason, you are no longer an employee on the date we grant
new options, you will not receive any new options. You are reminded that unless
expressly provided otherwise in your employment agreement, your employment with
Pinnacle will remain "at-will" and can be terminated by you or Pinnacle at any
time, with or without cause or notice. (Page 29)

-5-

Moreover, even if we accept your tendered options, we will not grant new
options to you if we are prohibited by applicable law or regulations from doing
so. Such a prohibition could result from changes in SEC rules, regulations or
policies or Nasdaq listing requirements. We will use reasonable efforts to avoid
any such prohibitions, but if it is applicable throughout the period after the
first business day that is at least six (6) months and one (1) day after we
cancel the options accepted for exchange (the period after the date we intend to
grant the new options), you will not be granted a new option. We do not
anticipate any such prohibitions and are referring to the possibility in an
abundance of caution. (Page 29)

16. If I choose to tender an option which is eligible for exchange, do I have to
tender all the shares in that option?

Yes. We will not accept partial tenders of the unexercised options subject
to any individual option grant. However, you may tender the unexercised portion
of any of your options. Accordingly, you may tender one or more of your option
grants, but you must tender either all of the unexercised shares subject to each
grant or none of the shares for that particular grant. For example and except as
otherwise described below, if you hold (i) an option to purchase 1,000 shares at
$5.00 per share, 700 of which you have already exercised, (ii) an option to
purchase 1,000 shares at an exercise price of $10.00 per share and (iii) an
option to purchase 2,000 shares at an exercise price of $15.00 per share, you
may tender:

. none of your options,

. options with respect to the 300 remaining unexercised shares under the
first option grant,

. options with respect to all 1,000 shares under the second option
grant,

. options with respect to all 2,000 shares under the third option grant,

. all unexercised options with respect to two of the three option
grants, or

. all unexercised options under all three of the option grants.

You may not tender options with respect to only a partial amount of
unexercised shares under any particular option grant. (Page 17)

Also, if you decide to tender any of your options, then you must tender all
of your options that were granted to you during the six (6) month period prior
to the commencement of the offer. For example, if you received an
option grant in March 2001 and a grant in September 2001 and you want to tender
your March 2001 option grant, you would also be required to tender your
September 2001 option grant. (Page 17).

-6-

17. What happens to options that I choose not to tender or that are not
accepted for exchange?

Options that you choose not to tender for exchange or that we do not accept
for exchange remain outstanding until they expire by their terms and retain
their current exercise price and current vesting schedule.

You should note that there is a risk that any incentive stock options you
have may be affected, even if you do not participate in the exchange. We believe
that eligible options that you choose not to tender for exchange will not be
subject to current U.S. federal income tax if you do not elect to participate in
the option exchange program. We also believe that the option exchange program
will not change the U.S. federal income tax treatment of subsequent grants and
exercises of your incentive stock options (and sales of shares acquired upon
exercises of such options) if you do not participate in this offer to exchange
options. However, the IRS may characterize this offer to exchange options as a
"modification" of those incentive stock options, even if you decline to
participate. In 1991, the IRS issued a private letter ruling in which another
company's option exchange program was characterized as a "modification" of all
of the incentive stock options that could be exchanged. This does not
necessarily mean that our offer to exchange options will be viewed the same way.
Private letter rulings given by the IRS contain the IRS's opinion regarding only
the specific facts presented by a specific person or company. The person or
company receiving the letter may rely on it, but no other person or company may
rely on the letter ruling, nor may they assume the same opinion would apply to
their situation, even if the facts at issue are similar. While such letters do
not provide certainty, they may indicate how the IRS will view a similar
situation. We therefore do not know if the IRS will assert the position that our
offer constitutes a "modification" of incentive stock options eligible for
tender. A successful assertion by the IRS of this position could extend the
options' holding period to qualify for favorable tax treatment. Accordingly, to
the extent you dispose of your incentive stock option shares prior to the lapse
of the new extended holding period, your incentive stock option could be taxed
similarly to a nonstatutory stock option.

18. Will I have to pay taxes if I exchange my options in the offer?

If you exchange your current options for new options, you should not be
required under current law to recognize income for U.S. federal income tax
purposes at the time of the exchange. Further, at the grant date of the new
options, you will not be required under current law to recognize income for U.S.
federal income tax purposes.

For all employees, we recommend that you consult with your own tax advisor
to determine the tax consequences of the offer that pertain to you. If you are
living or working in the United States, but are also subject to the tax laws in
another country, you should be aware that there may be other tax and social
insurance consequences which may apply to you; you should be certain to consult
your own advisors. In addition, we strongly urge you to read Sections 14 through
18 of the Offer to Exchange for a discussion of tax consequences which may apply
to you as a result of participation in this offer. (Page 30)

-7-

19. If my current options are incentive stock options, will my new options be
incentive stock options?

If your current options are incentive stock options, your new options will
be granted as incentive stock options to the maximum extent they qualify as
incentive stock options under the tax laws on the date of the grant of the new
options. For options to qualify as incentive stock options under the current tax
laws, the value of shares subject to options that first become exercisable by
the option holder in any calendar year cannot exceed $100,000, as determined
using the option exercise price. The excess value is deemed to be a nonstatutory
options stock option, which is an option that is not qualified to be an
incentive stock option under the current tax laws. (Page 38)

20. When will my new options expire?

Your new options will expire ten (10) years from the date of grant, or
earlier if your employment with Pinnacle terminates.

21. When does the offer expire? Can the offer be extended, and if so,
how will I be notified if it is extended?

The offer expires on December 17, 2001, at 9:00 p.m., Pacific Standard
Time, unless we extend it. We may, in our discretion, extend the offer at any
time, but we cannot assure you that the offer will be extended or, if extended,
for how long. If the offer is extended, we will make a public announcement of
the extension no later than 6:00 a.m., Pacific Standard Time, on the next
business day following the previously scheduled expiration of the offer period.
(Page 43)

22. How do I tender my options?

If you decide to tender your options, you must deliver, before 9:00 p.m.,
Pacific Standard Time, on December 17, 2001 (or such later date and time as we
may extend the expiration of the offer), a properly completed and executed
Election Form and any other documents required by the Election Form via
facsimile (fax # (000) 000-0000) or hand delivery to Xxxxxxx Xxxxx. This is a
one-time offer, and we will strictly enforce the tender offer period. We reserve
the right to reject any or all tenders of options that we determine are not in
appropriate form or that we determine are unlawful to accept. Subject to our
rights to extend, terminate and amend the offer, we presently expect that we
will accept all properly tendered options promptly after the expiration of the
offer. (Page 19)

23. During what period of time may I withdraw previously tendered options?

You may withdraw your tendered options at any time before the offer expires
at 9:00 p.m., Pacific Standard Time, on December 17, 2001. If we extend the
offer beyond that time, you may withdraw your tendered options at any time until
the extended expiration of the offer. In addition, although we currently intend
to accept validly tendered options promptly after the expiration of this offer,
if we have not accepted your tendered options by 9:00 p.m., Pacific Standard
Time, on January 11, 2002, you may withdraw your tendered options at any time
after January 11, 2002. To

-8-

withdraw tendered options, you must deliver to us via facsimile (fax # (650)
000-0000) or hand delivery to Xxxxxxx Xxxxx a signed Notice to Withdraw from the
Offer, with the required information while you still have the right to withdraw
the tendered options. Once you have withdrawn options, you may re-tender options
only by again following the delivery procedures described above. (Page 20)

Please note that if you submit a Notice to Withdraw from the Offer, you
will no longer participate in the offer. If you do not wish to withdraw all your
tendered options from the offer, you should not submit a Notice to Withdraw from
the Offer. If you wish to change your mind about which options to tender, you
must submit a new Election Form. Please read the following question and answer
regarding a change in election.

24. Can I change my election regarding particular tendered options?

Yes, you may change your election regarding particular tendered options at
any time before the offer expires at 9:00 p.m., Pacific Standard Time, on
December 17, 2001. If we extend the offer beyond that time, you may change your
election regarding particular tendered options at any time until the extended
expiration of the offer. In order to change your election, you must deliver to
us a new Election Form via facsimile (fax # (000) 000-0000) or hand delivery to
Xxxxxxx Xxxxx, which includes the information regarding your new election, and
is signed and clearly dated after your original Election Form. (Page 20)

25. What do Pinnacle and the Board of Directors think of the offer?

Although our Board of Directors has approved the offer, neither we nor our
Board of Directors makes any recommendation as to whether you should tender or
not tender your options. You must make your own decision whether or not to
tender options. For questions regarding tax implications or other
investment-related questions, you should talk to your own legal counsel,
accountant and/or financial advisor.

26. Whom can you talk to if you have questions about the offer?

CERTAIN RISKS
OF PARTICIPATING IN THE OFFER

Participation in the offer involves a number of potential risks, including
those described below. This list highlights the material risks of participating
in this offer. If you are living or working in the United States, but are also
subject to the tax laws in another country, you should be aware that there may
be other tax and social insurance consequences which may apply to you; you
should be certain to consult your own advisors. Eligible participants should
carefully consider these risks and are encouraged to speak with an investment
and tax advisor as necessary before deciding to participate in the offer. In
addition, we strongly urge you to read Sections 14 through 18 in this Offer to
Exchange discussing tax consequences for tax residents in the United States,
France, Germany, Japan and the United Kingdom, as well as the rest of this Offer
to Exchange, the Memorandum from Xxxx X. Xxxxxxx dated November 16, 2001, the
Election Form and the Notice to Withdraw from the Offer for a more in-depth
discussion of the risks which may apply to you before deciding to participate in
the exchange offer.

ECONOMIC RISKS
--------------

- Participation in the offer will make you ineligible to receive any option
grants until June 19, 2002 at the earliest.

Employees are generally eligible to receive option grants at any time that
the Board of Directors or Compensation Committee chooses to make them. However,
if you participate in the offer, you will not be eligible to receive any option
grants until June 19, 2002 at the earliest.

- If our stock price increases after the date your tendered options are
cancelled, your cancelled options might have been worth more than the
replacement options that you have received in exchange for them.

For example, if you cancel options with a $10 strike price, and Pinnacle's
stock appreciates to $20 per share when the replacement grants are made, your
replacement option will have a higher strike price than the cancelled option.

- If Pinnacle is acquired by or merges with another company, your cancelled
options might have been worth more than the replacement options that you
have received in exchange for them.

These types of transactions could have substantial effects on our stock
price, including potentially substantial appreciation in the price of our stock.
Depending on the structure of this type of transaction, tendering option holders
might be deprived of any further price appreciation in the stock associated with
the new options.

In addition, in the event of an acquisition of our company for stock,
tendering option holders might receive options to purchase shares of a successor
to our company, where the exercise price of the new options would be equal to
the fair market value of such acquiror's stock on the New Option

-10-

Grant Date. The New Option Grant Date, expected to be June 19, 2002, will be at
least six (6) months and one (1) day after the cancellation of the tendered
options. Option holders who do not tender in the offer will have their
outstanding options treated in accordance with the terms of the plan they are
granted under and if their options are assumed by the successor to our company,
those options would be priced in accordance with the terms of the transaction.
This could potentially result in a greater financial benefit for those option
holders who opted not to participate in this offer and who instead retained
their original options.

- If your employment terminates prior to the grant of the replacement option,
you will receive neither a replacement option nor the return of your
cancelled option.

Once your option is cancelled, you will no longer have any rights with
respect to the option. Accordingly, if your employment terminates for any reason
prior to the grant of the replacement option, you will not have the benefit of
either the cancelled option or the replacement option.

- If your employment terminates as part of a reduction-in-force prior to the
grant of the replacement option, you will not receive either a replacement
option or the return of your cancelled option.

Pinnacle's revenues are dependent on the health of the economy and the
growth of its customers and potential future customers. If the economic
conditions in the United States remain stagnant or worsen or if a wider or
global economic slowdown occurs, our business, operating results, and financial
condition may be materially adversely impacted and we may undertake various
measures to reduce our expenses including, but not limited to, a
reduction-in-force of certain of our employees. Should your employment be
terminated as part of any such reduction-in-force, you will not have the benefit
of either the cancelled option or the replacement option.

- If your employment terminates as a result of an acquisition or merger of
Pinnacle prior to the grant of the replacement option, you will not receive
either a replacement option or the return of your cancelled option.

If another company acquires Pinnacle, that company may, as part of the
transaction or otherwise, decide to terminate some or all of our employees prior
to the grant of new options under this option exchange program. Termination for
this, or any other, reason before the replacement option is granted means that
you will not receive the replacement option, nor will you receive any other
consideration for the options that were cancelled.

TAX-RELATED RISKS FOR U.S. RESIDENTS
------------------------------------

- Your replacement option may be a nonstatutory stock option, whereas your
cancelled option may have been an incentive stock option.

If your cancelled option was an incentive stock option, your new option
will be an incentive stock option, but only to the extent that it qualifies
under the Internal Revenue Code of 1986, as amended. For options to qualify as
incentive stock options, the value of shares subject to options

-11-

that first become exercisable by the option holder in any calendar year cannot
exceed $100,000, as determined by the option exercise price. It is possible that
by participating in this exchange, your options will exceed this limit and will
be treated as nonstatutory stock options. In general, nonstatutory stock options
are less favorable to you from a tax perspective. For more detailed information,
please read the rest of the Offer to Exchange, and see the tax disclosure set
forth in the Form S-8 prospectus for each of the 1996 Plan and the 1996
Supplemental Plan, which is attached as exhibit (d)(2) to the Schedule TO filed
with the SEC in connection with this Offer to Exchange.

- Even if you elect not to participate in the option exchange program, your
incentive stock options may be affected.

We believe that you will not be subject to current U.S. federal income tax
if you do not elect to participate in the option exchange program. We also
believe that the option exchange program will not change the U.S. federal income
tax treatment of subsequent grants and exercises of your incentive stock options
(and sales of shares acquired upon exercises of such options) if you do not
participate in this offer to exchange options. However, the IRS may characterize
this offer to exchange options as a "modification" of those incentive stock
options, even if you decline to participate. In 1991, the IRS issued a private
letter ruling in which another company's option exchange program was
characterized as a "modification" of all of the incentive stock options that
could be exchanged. This does not necessarily mean that our offer to exchange
options will be viewed the same way. Private letter rulings given by the IRS
contain the IRS's opinion regarding only the specific facts presented by a
specific person or company. The person or company receiving the letter may rely
on it, but no other person or company may rely on the letter ruling, nor may
they assume the same opinion would apply to their situation, even if the facts
at issue are similar. While such letters do not provide certainty, they may
indicate how the IRS will view a similar situation. We therefore do not know if
the IRS will assert the position that our offer constitutes a "modification" of
incentive stock options eligible for tender. A successful assertion by the IRS
of this position could extend the options' holding period to qualify for
favorable tax treatment. Accordingly, to the extent you dispose of your
incentive stock option shares prior to the lapse of the new extended holding
period, your incentive stock option could be taxed similarly to a nonstatutory
stock option.

TAX-RELATED RISKS FOR TAX RESIDENTS OF FRANCE
---------------------------------------------

Under general tax principles in France, you will not be subject to current
tax at the time of cancellation of your options if you elect to participate in
the exchange program. Please see Section 15 for a more detailed discussion of
the potential tax consequences of participation in the option exchange program.
We strongly recommend that you consult with your personal tax advisor prior to
participating in the option exchange program.

If you elect not to participate in the option exchange program, the
treatment of your "old" options will be the same as the treatment of the new
options, as described in Section 15.

-12-

TAX-RELATED RISKS FOR TAX RESIDENTS OF GERMANY
----------------------------------------------

Since there are no specific rules on the exchange of stock options, it is
possible that the cancellation of your old options will be considered a taxable
event by the German tax authorities. You will not be subject to tax on the new
option when it is granted, but you will be subject to tax when you exercise the
new options. You will also be subject to tax upon the sale of the shares subject
to the option, unless you have met certain conditions. Please see Section 16 for
a more detailed discussion of the tax consequences of participation in the
option exchange program. We strongly recommend that you consult with your
personal tax advisor prior to participating in the option exchange program.

We believe that you will not be subject to current tax in Germany if you
elect not to participate in the option exchange program. Taxation at date of
exercising the old options will most likely considered the taxable event.

TAX-RELATED RISKS FOR TAX RESIDENTS OF JAPAN
--------------------------------------------

Under general tax principles in Japan, we believe that you will not be
subject to current tax in Japan at the time of cancellation if you elect to
participate in the option exchange program. Please see Section 17 for a more
detailed discussion of the potential tax consequences of participation in the
offer. We strongly recommend that you consult with your personal tax advisor
prior to participating in the option exchange program.

We believe you will not be subject to current tax in Japan if you elect not
to participate in the option exchange program.

TAX-RELATED RISKS FOR TAX RESIDENTS OF THE UNITED KINGDOM
---------------------------------------------------------

Under general tax principles in the United Kingdom, you will not be subject
to current tax at the time of cancellation if you elect to participate in the
option exchange program. It should be noted that the value of shares could
fluctuate downward as well as upward.

When you exercise the new option you will be subject to income tax on the
difference between the fair market value of the shares on the date of exercise
and the exercise price. You will also be liable to pay employee's National
Insurance Contributions ("NICs") on the proceeds at exercise if your earnings do
not already exceed the maximum limit for NIC purposes - (pound)575 per week for
the U.K. tax year April 6, 2001 to April 5, 2002.

-13-

When you sell your shares, you may be subject to capital gains tax. The tax
is due on any increase in the value of the stock between the date on which you
exercised your options and the sale proceeds realized when you sell the shares.
Any capital gains tax you may owe is subject to an annual personal exemption
(currently (pound)7,500 for the U.K. tax year April 6, 2001 to April 5, 2002)
and to taper relief calculated with reference to the period of time during which
you held the shares.

Please see Section 18 for a more detailed discussion of the potential tax
consequences of participation in the option exchange program. We strongly
recommend that you consult with your personal tax advisor prior to participating
in the option exchange program.

We believe you will not be subject to current tax in the United Kingdom if
you elect not to participate in the option exchange program.

TAX-RELATED RISKS FOR TAX RESIDENTS OF NON-U.S. COUNTRIES
---------------------------------------------------------

If you are eligible for this exchange because you are an employee living or
working in the United States, but are also subject to the tax laws in another
country, you should be aware that there may be other tax and social insurance
consequences which may apply to you. You should be certain to consult your own
tax advisors to discuss these consequences.

BUSINESS-RELATED RISKS
----------------------

For a description of risks related to Pinnacle's business, please see
Section 23 of this Offer to Exchange.

-14-

INTRODUCTION

Pinnacle is offering to exchange certain outstanding options to purchase
shares of Pinnacle common stock held by eligible employees for new options we
will grant under the same Pinnacle stock plan pursuant to which your old options
were granted. Outstanding options issued under the 1996 Plan or the 1996
Supplemental Plan are eligible to be exchanged. An "eligible employee" refers to
employees of Pinnacle or its subsidiaries who are employees as of the date the
offer commences and remain employees through the date the tendered options are
cancelled; however, only employees who live or work in the United States,
France, Germany, Japan or the United Kingdom are eligible to participate in the
exchange offer. In addition, members of our Board of Directors and all employees
who are defined as officers for purposes of Section 16(b) of the Exchange Act
("Section 16(b) officers"), are not eligible to participate in the exchange
offer. Our directors and the Section 16(b) officers are listed on Schedule A-1
to this Offer to Exchange. We are making the offer upon the terms and the
conditions described in this Offer to Exchange Certain Outstanding Options for
New Options and in the related Memorandum from Xxxx X. Xxxxxxx dated November
16, 2001, the Election Form and the Notice to Withdraw from the Offer (which
together, as they may be amended from time to time, constitute the "offer" or
"program").

The number of shares subject to the new options to be granted to each
eligible employee will be equal to the number of shares subject to the options
tendered by the eligible employee and accepted for exchange. Subject to the
terms and conditions of this offer, we will grant the new options on the first
business day which is at least six (6) months and one (1) day after the date we
cancel the options accepted for exchange. The grant date for the new options
will be on or about June 19, 2002, unless the offer is extended, in which case
the grant date of the new options will be at least six (6) months and one (1)
day after the cancellation of the options accepted for exchange. You may only
tender options for all or none of the unexercised shares subject to an
individual option grant. All tendered options accepted by us through the offer
will be cancelled on the day following the date the offer expires or as soon as
possible thereafter (the "Cancellation Date"). If you tender any option grant
for exchange, you will be required to also tender all option grants that you
received during the six (6) month period immediately prior to the commencement
of this offer. This offer commenced on November 16, 2001, which means that if
you participate in the offer, you will be required to tender all options granted
to you since May 16, 2001, including any options granted between the date the
offer commences and the date the options are cancelled.

The offer is not conditioned on a minimum number of options being tendered.
The offer is subject to conditions that we describe in Section 7 of this Offer
to Exchange.

If you tender options for exchange as described in the offer and we accept
your tendered options, then, subject to the terms of this offer, we will grant
you new options under the particular Pinnacle stock option plan pursuant to
which your old options were granted.

-15-

Each new option will be exercisable for the same number of shares as were
exercisable under the tendered options. The vesting start date for each new
option will be the date that the new options are granted. The new options will,
subject to your continued employment with Pinnacle on the date the new options
are granted, vest according to the following schedule:

. 1/3 of the shares subject to the new option will vest immediately on
the date that the new option is granted; and

. An employee cancels an option to purchase 3,600 shares that is 1/2
vested at the time of cancellation.

. The new option grant occurs six (6) months and one (1) day after the
cancellation.

. The new option will be 1/3rd vested at the time of grant, so the
employee is vested as to 1,200 of the shares subject to the new option
(which is 1/3rd of 3,600).

As of November 5, 2001, options to purchase 13,024,477 of our shares were
issued and outstanding under the 1996 Plan and the 1996 Supplemental Plan
combined, and options to purchase 1,730,015 of our shares were issued and
outstanding outside of the two plans. Of the total options issued and
outstanding, options to purchase approximately 11,221,312 of our shares,
constituting approximately 76% of the aggregate 14,754,492 options outstanding,
were held by employees eligible to participate in the offer.

THE OFFER

1. Eligibility.
-----------

Employees are "eligible employees" if they are employees of Pinnacle or one
of Pinnacle's subsidiaries as of the date the offer commences and remain
employees through the date on which the tendered options are cancelled if, and
only if, they live or work in the United States, France, Germany, Japan or the
United Kingdom. However, members of the Board of Directors and all employees who
are defined as "officers" for purposes of Section 16(b) of the Exchange Act are
not eligible to participate in the offer. Our directors and the employees of
Pinnacle who are officers for the purposes of such Section 16(b) are listed on
Schedule A-1 to this Offer to Exchange.

In order to receive a new option, you must remain an employee as of the
date the new options are granted (the "New Option Grant Date"), which will be at
least six (6) months and one (1) day after the Cancellation Date. If Pinnacle
does not extend the offer, the new options will be granted on June 19, 2002.

Only outstanding, unexercised options granted pursuant to the 1996 Plan and
the 1996 Supplemental Plan may be tendered for exchange. Each option grant that
is tendered for exchange must be tendered for the entirety of the portion that
remains outstanding and unexercised. If you tender any options for exchange, all
options granted in the six (6) months prior to the commencement of the offer
must also be tendered.

2. Number of options; expiration date.
----------------------------------

Subject to the terms and conditions of the offer, we will exchange
outstanding, unexercised options held by eligible employees that are properly
tendered in accordance with Section 4 of this Offer to Exchange and not validly
withdrawn in accordance with Section 5 of this Offer to Exchange before the
"expiration date," as defined below, in return for new options. We will not
accept partial tenders of the unexercised options subject to any individual
option grant. Therefore, you must tender options for either all or none of the
unexercised shares subject to each of your eligible options. In addition, if you
tender any option grant for exchange, you will be required to also tender all
option grants that you received during the six (6) month period prior to the
date offer commenced. This offer commenced on November 16, 2001, which means
that if you participate in the offer, you will be required to tender all options
granted to you since May 16, 2001, including any options granted between the
date the offer commences and the Cancellation Date.

If your options are properly tendered and accepted for exchange, the
options will be cancelled and, subject to the terms of this offer, you will be
entitled to receive one or more new options to purchase the number of shares of
common stock equal to the number of shares subject to the options tendered by
you and accepted for exchange, subject to adjustments for any stock splits,
stock dividends and similar events. All new options will be subject to the terms
of the particular Pinnacle stock option plan pursuant to which your old options
were granted, and to a new option agreement between you and us. If, for any
reason, you do not remain an employee of Pinnacle or its subsidiaries through
the date we grant the new options, you will not receive any new options or other
consideration in exchange for your tendered options that have been accepted for
exchange. This

-17-

means that if you quit, with or without a good reason, or die or we terminate
your employment, with or without cause, prior to the date we grant the new
options, you will not receive anything for the options that you tendered and we
cancelled.

The term "expiration date" means 9:00 p.m., Pacific Standard Time, on
December 17, 2001, unless and until we, in our discretion, have extended the
period of time during which the offer will remain open, in which event the term
"expiration date" refers to the latest time and date at which the offer, as so
extended, expires. See Section 19 of this Offer to Exchange for a description of
our rights to extend, delay, terminate and amend the offer.

If we decide to take any of the following actions, we will publish notice
or otherwise inform you in writing of such action:

. we increase or decrease the amount of consideration offered for the
options,

. we decrease the number of options eligible to be tendered in the
offer, or

. we increase the number of options eligible to be tendered in the
offer by an amount that exceeds 2% of the shares issuable upon
exercise of the options that are subject to the offer immediately
prior to the increase

If the offer is scheduled to expire at any time earlier than the tenth
(10th) business day from, and including, the date that notice of the increase or
decrease is first published, sent or given in the manner specified in Section 19
of this Offer to Exchange, we will extend the offer so that the offer is open at
least ten (10) business days following the publication, sending or giving of
notice.

We will also notify you of any other material change in the information
contained in this Offer to Exchange.

For purposes of the offer, a "business day" means any day other than a
Saturday, Sunday or federal holiday and consists of the time period from 12:01
a.m. through 12:00 midnight, Eastern Standard Time.

3. Purpose of the offer.
--------------------

We issued the options outstanding to:

. provide our eligible employees with additional incentive and to
promote the success of our business, and

. encourage our eligible employees to continue their employment with us.

One of the keys to our continued growth and success is the retention of our
most valuable asset, our employees. The offer provides an opportunity for us to
offer our eligible employees a valuable incentive to stay with Pinnacle. Some of
our outstanding options, whether or not they are

-18-

currently exercisable, have exercise prices that are significantly higher than
the current market price of our shares. We believe these options are unlikely to
be exercised in the foreseeable future. By making this offer to exchange
outstanding options for new options that will have an exercise price at least
equal to the market value of the shares on the grant date, we intend to provide
our eligible employees with the benefit of owning options that over time may
have a greater potential to increase in value, create better performance
incentives for employees and thereby maximize shareholder value. Because we will
not grant new options until at least six (6) months and one (1) day after the
date we cancel the options accepted for exchange, the new options may have a
higher exercise price than some or all of our current outstanding options.

Neither we nor our Board of Directors makes any recommendation as to
whether you should tender or not tender your options, nor have we authorized any
person to make any such recommendation. You are urged to evaluate carefully all
of the information in this Offer to Exchange and to consult your own investment
and tax advisors. You must make your own decision whether or not to tender your
options for exchange.

4. Procedures for tendering options.
--------------------------------

Proper Tender of Options.
------------------------

To validly tender your options through the offer, you must, in accordance
with the terms of the Election Form, properly complete, execute and deliver the
Election Form to us via facsimile (fax # (000) 000-0000) or hand delivery to
Xxxxxxx Xxxxx, along with any other required documents. Xxxxxxx Xxxxx must
receive all of the required documents before the expiration date. The expiration
date is 9:00 p.m. Pacific Standard Time on December 17, 2001.

The delivery of all documents, including Election Forms and any Notices to
Change Election from Accept to Reject and any other required documents, is at
your risk. We intend to confirm the receipt of your Election Form within two
(2) business days; if you have not received such a confirmation of receipt, it
is your responsibility to ensure that your Election Form has been received by
us.

Determination of Validity; Rejection of Options; Waiver of Defects; No
----------------------------------------------------------------------
Obligation to Give Notice of Defects.
------------------------------------

We will determine, in our discretion, all questions as to the form of
documents and the validity, form, eligibility, including time of receipt, and
acceptance of any tender of options. Our determination of these matters will be
final and binding on all parties. We reserve the right to reject any or all
tenders of options that we determine are not in appropriate form or that we
determine are unlawful to accept. Otherwise, we will accept properly and timely
tendered options that are not validly withdrawn. We also reserve the right to
waive any of the conditions of the offer for all option holders or waive any
defect or irregularity in any tender of any particular options or for any
particular option holder. No tender of options will be deemed to have been
properly made until all defects or irregularities have been cured by the
tendering option holder or waived by us. Neither we nor any other person is
obligated to give notice of any defects or irregularities in tenders, nor will
anyone incur any liability

-19-

for failure to give any notice. This is a one-time offer, and we will strictly
enforce the offer period, subject only to an extension which we may grant in our
sole discretion.

Our Acceptance Constitutes an Agreement.
---------------------------------------

Your tender of options pursuant to the procedures described above
constitutes your acceptance of the terms and conditions of the offer. Our
acceptance for exchange of your options tendered by you through the offer will
constitute a binding agreement between us and you upon the terms and subject to
the conditions of the offer.

Subject to our rights to extend, terminate and amend the offer, discussed
in Section 19 of this Offer to Exchange, we currently expect that we will accept
promptly after the expiration of the offer all properly tendered options that
have not been validly withdrawn.

5. Withdrawal Rights and Change of Election.
----------------------------------------

You may only withdraw your tendered options or change your election in
accordance with the provisions of this Section.

You may withdraw your tendered options at any time before 9:00 p.m.,
Pacific Standard Time, on December 17, 2001. If we extend the offer beyond that
time, you may withdraw your tendered options at any time until the extended
expiration of the offer. In addition, if we have not accepted your tendered
options for exchange by 9:00 p.m., Pacific Standard Time, on January 11, 2002,
you may withdraw your tendered options at any time after January 11, 2002.

To validly withdraw tendered options, you must deliver to Xxxxxxx Xxxxx via
facsimile (fax # (000) 000-0000) or hand delivery, in accordance with the
procedures listed in this Section 5, a signed and dated Notice to Withdraw from
the Offer, with the required information, while you still have the right to
withdraw the tendered options.

To validly change your election regarding the tender of particular options,
you must deliver a new Election Form to Xxxxxxx Xxxxx via facsimile (fax # (650)
000-0000) or hand delivery, in accordance with the procedures listed in this
Section 5. If you deliver a new Election Form that is properly signed and dated,
it will replace any previously submitted Election Form, which will be
disregarded. The new Election Form must be signed and dated and must specify:

. the name of the option holder who tendered the options,

. the grant number of all options to be tendered,

. the grant date of all options to be tendered,

. the exercise price of all options to be tendered, and

. the total number of unexercised option shares subject to each option
to be tendered.

-20-

Even if you change your election regarding the tender of certain option
grants, your continued participation in the offer means that you must tender all
grants received since May 16, 2001, including any options granted between the
date the offer commences and the Cancellation Date.

Except as described in the following sentences, the Notice to Withdraw from
the Offer and any new or amended Election Form must be executed by the option
holder who tendered the options to be withdrawn exactly as the option holder's
name appears on the option agreement or agreements evidencing such options. If
the option holder's name has legally been changed since the signing of the
option agreement, the option holder must submit proof of the legal name change.
If the signature is by a trustee, executor, administrator, guardian,
attorney-in-fact, officer of a corporation or another person acting in a
fiduciary or representative capacity, the signer's full title and proper
evidence of the authority of such person to act in that capacity must be
indicated on the notice of withdrawal.

You may not rescind any withdrawal, and any options you withdraw will
thereafter be deemed not properly tendered for purposes of the offer, unless you
properly re-tender those options before the expiration date by following the
procedures described in Section 5 of this Offer to Exchange.

Neither we nor any other person is obligated to give notice of any defects
or irregularities in any Notice to Withdraw from the Offer or any new or amended
Election Form, nor will anyone incur any liability for failure to give any
notice. We will determine, in our discretion, all questions as to the form and
validity, including time of receipt, of Notices to Withdraw from the Offer and
new or amended Election Forms. Our determination of these matters will be final
and binding.

6. Acceptance of options for exchange and issuance of new options.
--------------------------------------------------------------

Upon the terms and conditions of the offer and promptly following the
expiration date, we will accept for exchange and cancel eligible options
properly tendered and not validly withdrawn before the expiration date. Only
options issued under the 1996 Plan or the 1996 Supplemental Plan are eligible
options. Once the options are cancelled, you will no longer have any rights with
respect to those options. Subject to the terms and conditions of this offer, if
your options are properly tendered and accepted for exchange, these options will
be cancelled as of the date of our acceptance, which we anticipate to be
December 18, 2001, and you will be granted new options on the first business day
that is at least six (6) months and one (1) day after the date we cancel the
options accepted for exchange.

If the options you tendered were incentive stock options, your new options
will also be incentive stock options, to the extent they qualify as incentive
stock options under the Internal Revenue Code of 1986, as amended. All other
newly granted options will be nonstatutory stock options. Thus, subject to the
terms and conditions of this offer, if your options are properly tendered by
December 17, 2001, the scheduled expiration date of the offer, and accepted for
exchange and cancelled on December 18, 2001 you will be granted new options on
or about June 19, 2002. If we accept and cancel options properly tendered for
exchange after December 18, 2001, the period in which the new options will be
granted will be similarly delayed. Promptly after we accept and cancel options
tendered for exchange, we will issue to you a Promise to Grant Stock Option(s),

-21-

which will evidence our binding commitment to grant stock options to you on a
date no earlier than June 19, 2002 covering the same number of shares as the
options cancelled pursuant to this offer, provided that you remain an eligible
employee on the date on which the grant is to be made.

If we accept options you tender in the offer, we will defer any grant to
you of other options, such as annual, bonus or promotional options, for which
you may be eligible before the new option grant date until the new option grant
date, so that you will not be granted any new options for any reason until at
least six (6) months and one (1) day after any of your tendered options have
been cancelled. We will defer the grant to you of these other options in order
to avoid incurring compensation expense against our earnings as a result of
accounting rules that could apply to these interim option grants as a result of
the offer. We may issue to you a Promise to Grant Stock Option(s), which is a
binding commitment to grant you an option or options on a date no earlier than
June 19, 2002, provided that you remain an eligible employee on the date on
which the grant is to be made.

It is possible that, prior to the grant of new options, we might effect or
enter into an agreement such as a merger or stock acquisition whereby another
company would acquire Pinnacle. The Promise to Grant Stock Option(s) which we
will give you evidences our binding commitment to you, and any successor to our
company will honor that commitment. Accordingly, in the event of any such merger
or acquisition, the acquiror would be obligated to grant you a new stock option
on the New Option Grant Date, which is expected to be June 19, 2002 (assuming
that Pinnacle does not extend the offer), if you are an employee of the acquiror
or one of its subsidiaries on that date. Such a stock option could be for the
purchase of the acquiror's stock (as opposed to Pinnacle's) and as a result, the
number of shares subject to your new option would be adjusted. For example, if
we were acquired by means of a merger, the number of shares would be equal to
the number of our shares that you would have received, multiplied by the
exchange ratio that was used in the merger. Your new option to purchase such
acquiror's stock would have an exercise price equal to the fair market value of
such acquiror's stock on the New Option Grant Date.

Your new options will entitle you to purchase the number of shares which is
equal to the number of shares subject to the options you tender, as adjusted for
any stock splits, stock dividends and similar events. If, for any reason, you
are not an employee of Pinnacle, its subsidiaries or a successor entity through
the date we grant the new options, you will not receive any new options or other
consideration in exchange for your tendered options which have been cancelled
pursuant to this offer.

We will not accept partial tenders of the unexercised options subject to
any individual option grant. However, you may tender the unexercised portion of
any option. Accordingly, you may tender one or more of your option grants, but
you must tender either all of the unexercised shares subject to that option or
none of those shares. In addition, if you tender any option grant for exchange,
you will be required to also tender all option grants that you received during
the six (6) month period prior to the commencement of the offer. This offer
commenced on November 16, 2001, which means that if you participate in the
offer, you will be required to tender all options granted to you since May 16,
2001, including any options granted between the date the offer commences and the
Cancellation Date.

-22-

Within two (2) business days of the receipt of your Election Form or your
Notice to Withdraw from the Offer, Pinnacle intends to send via either e-mail or
regular mail the option holder a Confirmation of Receipt. However, this is not
by itself an acceptance of the options for exchange. For purposes of the offer,
we will be deemed to have accepted options for exchange that are validly
tendered and not properly withdrawn as of the time when we give oral or written
notice to Xxxxxxx Xxxxx, or to the option holders of our acceptance for exchange
of such options, which notice may be made by press release. Subject to our
rights to extend, terminate and amend the offer, discussed in Section 15 of this
Offer to Exchange, we currently expect that we will accept promptly after the
expiration of the offer all properly tendered options that are not validly
withdrawn. Options accepted for exchange will be cancelled on the Cancellation
Date, which we presently expect to be December 18, 2001.

7. Conditions of the offer.
-----------------------

Notwithstanding any other provision of the offer, we will not be required
to accept any options tendered for exchange, and we may terminate or amend the
offer, or postpone our acceptance and cancellation of any options tendered for
exchange, in each case, subject to Rule 13e-4(f)(5) under the Exchange Act, if
at any time on or after November 16, 2001, and prior to the expiration date, any
of the following events has occurred, or has been determined by us to have
occurred, and, in our reasonable judgment in any case and regardless of the
circumstances giving rise to the event, including any action or omission to act
by us, the occurrence of such event or events makes it inadvisable for us to
proceed with the offer or with such acceptance and cancellation of options
tendered for exchange:

. there shall have been threatened or instituted or be pending any
action or proceeding by any governmental, regulatory or administrative
agency or authority that directly or indirectly challenges the making
of the offer, the acquisition of some or all of the tendered options
pursuant to the offer, or the issuance of new options, or otherwise
relates in any manner to the offer, or that, in our reasonable
judgment, could materially and adversely affect our business,
condition, income, operations or prospects or materially impair the
contemplated benefits of the offer to Pinnacle;

. there shall have been any action threatened, pending or taken, or
approval withheld, or any statute, rule, regulation, judgment, order
or injunction threatened, proposed, sought, promulgated, enacted,
entered, amended, enforced or deemed to be eligible to the offer or
Pinnacle, by any court or any authority, agency or tribunal that, in
our reasonable judgment, would or might directly or indirectly:

(1) make the acceptance for exchange of, or issuance of new options
for, some or all of the tendered options illegal or otherwise
restrict or prohibit consummation of the offer or that otherwise
relates in any manner to the offer;

(2) delay or restrict our ability, or render us unable, to accept for
exchange, or issue new options for, some or all of the tendered
options;

-23-

(3) materially impair the contemplated benefits of the offer to
Pinnacle; or

(4) materially and adversely affect Pinnacle's business, condition,
income, operations or prospects;

. there shall have occurred any change, development, clarification or
position taken in generally accepted accounting standards that could
or would require us to record compensation expense against our
earnings in connection with the offer for financial reporting
purposes;

. a tender or exchange offer for some or all of our shares, or a merger
or acquisition proposal for Pinnacle, shall have been proposed,
announced or made by another person or entity or shall have been
publicly disclosed;

. any change or changes shall have occurred in Pinnacle's business,
condition, assets, income, operations, prospects or stock ownership
that, in our reasonable judgment, is or may be material to Pinnacle or
may materially impair the contemplated benefits of the offer to
Pinnacle; or

. any of our executive officers or directors shall have tendered any of
their options pursuant to the offer

The conditions to the offer are for Pinnacle's benefit. We may assert them
in our discretion regardless of the circumstances giving rise to them before the
expiration date. We may waive them, in whole or in part, at any time and from
time to time prior to the expiration date, in our discretion, whether or not we
waive any other condition to the offer. Our failure at any time to exercise any
of these rights will not be deemed a waiver of any such rights. The waiver of
any of these rights with respect to particular facts and circumstances will not
be deemed a waiver with respect to any other facts and circumstances. Any
determination we make concerning the events described in this Section 7 will be
final and binding upon all persons.

8. Price range of shares underlying the options.
--------------------------------------------

The shares underlying your options are currently traded on the Nasdaq
National Market under the symbol "PCLE". The following table shows, for the
periods indicated, the high and low sales prices per share/1/ of our common
stock as reported by the Nasdaq National Market.

As of November 9, 2001, the last reported sale price during regular trading
hours of our common stock, as reported by the Nasdaq National Market, was $4.30
per share.

We recommend that you evaluate current market quotes for our common stock,
among other factors, before deciding whether or not to tender your options.

9. Source and amount of consideration; terms of new options
--------------------------------------------------------
Consideration.
-------------

We will issue new options to purchase shares of common stock under either
the 1996 Plan or the 1996 Supplemental Plan, depending upon the plan pursuant to
which your eligible outstanding options were issued, so that your new options
are granted under the same plan(s) as the options you properly tendered and
accepted for exchange and cancellation by us. The number of shares subject to
the new options to be granted to each option holder will be equal to the number
of shares subject to the options tendered by the option holder and accepted for
exchange and cancelled by us, as adjusted for any stock splits, reverse stock
splits, stock dividends and similar events. If we receive and accept tenders of
all outstanding options from eligible employees, subject to the terms and
conditions of this offer we will grant new options to purchase a total of
approximately 10,474,177 shares of common stock. The shares issuable upon
exercise of these new options would equal approximately 83% of the total shares
of our common stock outstanding as of November 5, 2001.

Terms of New Options.
--------------------

The new options will be granted under either the 1996 Plan or the 1996
Supplemental Plan, depending upon the plan pursuant to which your old options
were issued. For every new option granted, a new option agreement will be
entered into between Pinnacle and each option holder who has tendered options in
the offer. The terms and conditions of the new options may vary from the terms
and conditions of the options tendered for exchange, but generally will not
substantially and adversely affect the rights of option holders. However, you
should note that new options will only be incentive stock options to the extent
they qualify under the Internal Revenue Code of 1986, as amended. For options to
qualify as incentive stock options, the value of shares subject to options that
first become exercisable by the option holder in any calendar year cannot exceed
$100,000, as

-25-

determined using the option exercise price. It is possible that by participating
in this exchange, your options will exceed this limit and will be treated as
nonstatutory stock options. Nonstatutory stock options receive tax treatment
which is generally less favorable than the treatment received by incentive stock
options. Please read "U.S. Federal Income Tax Consequences" later in this
Section, as well as Sections 14 through 18 of this Offer to Exchange for a
discussion of the potential tax consequences for tax residents of the United
States, France, Germany, Japan and the United Kingdom.

If you are living or working in the United States, but are also subject to
the tax laws in another country, you should be aware that there may be other tax
and social insurance consequences which may apply to you; you should be certain
to consult your own advisors to discuss these consequences. In addition, you
should note that because we will not grant new options until at least six (6)
months and one (1) day after the date we cancel the options accepted for
exchange, the new options may have a higher exercise price than some or all of
the options tendered for exchange. The following description summarizes the
material terms of each of the 1996 Plan, the 1996 Supplemental Plan and the
options granted under each plan.

1996 Stock Plan.
---------------

The maximum number of shares available for issuance through the exercise of
options granted under our 1996 Plan is 5,740,000 shares. Our 1996 Plan permits
the granting of options intended to qualify as incentive stock options under the
Internal Revenue Code and options that do not qualify as incentive stock
options, referred to as nonstatutory stock options.

Administration.
--------------

The 1996 Plan is administered by the Board of Directors or a committee
appointed by the Board of Directors (the "Administrator"). Subject to the other
provisions of the 1996 Plan, the Administrator has the power to determine the
terms and conditions of the options granted, including the exercise price, the
number of shares subject to the option and the exercisability of the options.

Term.
----

Options generally have a term of ten (10) years. Incentive Stock Options
granted to an employee who, at the time the incentive stock option is granted,
owns stock representing more than 10% of the voting rights of all classes of
stock of Pinnacle or an affiliate company have a term of no more than five (5)
years.

Termination.
-----------

-26-

permanent or total disability or death, you, or your executors, administrators,
legatees or distributees of your estate, may exercise any option held by you at
the date of your employment termination, to the extent that it was exercisable
immediately before such termination, within the time frame specified in your
option agreement or, if no time is specified, for one (1) year following such
termination.

The termination of your option under the circumstances specified in this
section will result in the termination of your interests in our 1996 Plan. In
addition, your option may terminate, together with our stock option plans and
all other outstanding options issued to other employees, following the
occurrence of certain corporate events, as described below.

Exercise Price.
--------------

Generally, the Administrator determines the exercise price at the time the
option is granted. For all eligible employees, the exercise price per share of
the new options will be one hundred percent (100%) of the fair market value of
Pinnacle's common stock on the date of grant of the new options, as determined
by the closing price of Pinnacle's common stock reported by the Nasdaq National
Market on the date of grant of the new options.

However, the exercise price may not be less than one hundred and ten
percent (110%) of the closing price per share reported by the Nasdaq National
Market on the date of grant for options intended to qualify as incentive stock
options, granted to an employee who, at the time the incentive stock option is
granted, owns stock representing more than ten percent (10%) of the voting
rights of all classes of stock of Pinnacle or an affiliate company.

Notwithstanding the above, incentive stock options and nonstatutory options
may be granted at an exercise price of less than one hundred percent (100%) of
the fair market value on the date of grant as determined by the closing price
reported by the Nasdaq National Market on the date of grant pursuant to a merger
or other corporate transaction.

Vesting and Exercise.
--------------------

Each stock option agreement specifies the term of the option and the date
when the option becomes exercisable. The terms of vesting are determined by the
Administrator. Options granted by us generally vest at a rate of 25% of the
shares subject to the option after twelve (12) months, and then 1/48th of the
shares subject to the option vest each month thereafter, provided the employee
remains continuously employed by Pinnacle.

. 1/3 of the shares subject to the new option will vest immediately on
the date that the new option is granted; and

-27-

. An employee cancels an option to purchase 3,600 shares that is 1/2
vested at the time of cancellation.

. The new option grant occurs six (6) months and one (1) day after the
cancellation.

. The new option will be 1/3rd vested at the time of grant, so the
employee is vested as to 1,200 of the shares subject to the new option
(which is 1/3rd of 3,600).

Payment of Exercise Price.
-------------------------

You may exercise your options, in whole or in part, by delivery of a
written or electronic notice of exercise to us and payment in full of the
eligible exercise price. The permissible methods of payment of the option
exercise price are determined by the Administrator and generally include the
following:

. cash;

. check;

. promissory note;

. certain other shares of our common stock;

. a reduction in the amount of our liability to the optionee;

. any other consideration and payment method for the issuance of shares
pursuant to the option as is permitted by applicable laws; or

. a combination of the foregoing methods.

-28-

Adjustments Upon Certain Events.
-------------------------------

Events Occurring before the New Option Grant Date. In the event there is a
-------------------------------------------------
merger or stock acquisition whereby Pinnacle is acquired by another company that
occurs after the expiration of the offer but before new options are granted
pursuant to this offer, the successor will honor any Promises to Grant Stock
Option(s). In the event of any such merger transaction, the successor would be
obligated to grant you a new stock option on or about June 19, 2002 (assuming
that Pinnacle does not extend the offer), which could be for the purchase of the
acquiror's stock (as opposed to Pinnacle's) and as a result, the number of
shares subject to your new option would be adjusted. For example, if we were
acquired by means of a merger, the number of shares would be equal to the number
of our shares that you would have received, multiplied by the exchange ratio
that was used in the merger. The new options for the purchase of the acquiror's
stock will have an exercise price equal to the fair market value of such
acquiror's stock on the New Option Grant Date.

Events Occurring after the New Option Grant Date. If there is a change in
------------------------------------------------
our capitalization, such as a stock split, reverse stock split, stock dividend
or other similar event, and the change results in an increase or decrease in the
number of issued shares without receipt of consideration by us, an appropriate
adjustment will be made to the price of each option and the number of shares
subject to each option.

In the event there is a liquidation or dissolution of Pinnacle, your
outstanding options will terminate immediately prior to the consummation of the
liquidation or dissolution. The Administrator may, however, provide for an
optionee to have the right to exercise the option until ten (10) days prior to
the liquidation or dissolution, including shares that would not otherwise be
exercisable pursuant to the option.

Per the terms of the 1996 Plan, in the event there is a sale of all or
substantially all of our assets, or we merge with another corporation, your
options may be assumed or replaced with new options of the successor
corporation; however, if the successor corporation refuses to assume or
substitute your options, you will fully vest in and have the right to exercise
the option in full, including shares that would not otherwise be vested or
exercisable.

-29-

of the transaction, than those options that are tendered for exchange. In
addition, the value of Pinnacle or the successor corporation could increase as a
result of an acquisition or merger, which could result in your current options
no longer being "underwater" or result in less benefit to option holders
participating in the offer. We cannot predict the effect of an acquisition of
Pinnacle or a merger on the option price or the value of the shares and
therefore urge you to take this possibility into consideration when deciding
whether to participate in the offer.

Termination of Employment Before the New Option Grant Date.
----------------------------------------------------------

If, for any reason, you are not an employee of Pinnacle from the date you
tender options through the date we grant the new options, you will not receive
any new options or any other consideration in exchange for your tendered options
that have been accepted for exchange. This means that if you quit, with or
without good reason, or die, or we terminate your employment, with or without
cause, before the date we grant the new options, you will not receive anything
for the options that you tendered and which we cancelled.

Transferability of Options.
---------------------------

New options, whether incentive stock options or nonstatutory stock options,
may not be transferred, other than by will or the laws of descent and
distribution. In the event of your death, options may be exercised by a person
who acquires the right to exercise the option by bequest or inheritance.

Registration of Option Shares.
-----------------------------

Five million seven hundred forty thousand (5,740,000) shares of common
stock issuable upon exercise of options under our 1996 Plan have been registered
under the Securities Act on registration statements on Form S-8 filed with the
SEC. All the shares issuable upon exercise of all new options to be granted
before the offer will be registered under the Securities Act. Unless you are one
of our affiliates, you will be able to sell your option shares free of any
transfer restrictions under applicable U.S. securities laws.

Income Tax Consequences.
-----------------------

You should refer to Sections 14 through 18 of this Offer to Exchange for a
discussion of the U.S. federal income tax consequences on tax residents of the
of the United States, France, Germany, Japan and the United Kingdom of the new
options and the options tendered for exchange, as well as the consequences of
accepting or rejecting the new options under this offer to exchange. If you are
living or working in the United States, but are also subject to the tax laws in
another country, you should be aware that there may be other tax and social
insurance consequences which may apply to you; we strongly recommend that you
consult with your own advisors to discuss the consequences to you of this
transaction.

-30-

1996 Supplemental Stock Plan.
----------------------------

The maximum number of shares available for issuance through the exercise of
options granted under our 1996 Supplemental Plan is 11,800,000 shares. Our 1996
Supplemental Plan permits the granting of options that do not qualify as
incentive stock options, referred to as nonstatutory stock options.

Administration.
--------------

The 1996 Supplemental Plan is administered by the Board of Directors or a
committee appointed by the Board of Directors (the "Supplemental Plan
Administrator"). Subject to the other provisions of the 1996 Supplemental Plan,
the Supplemental Plan Administrator has the power to determine the terms and
conditions of the options granted, including the exercise price, the number of
shares subject to the option and the exercisability of the options.

Term.
----

Options generally have a term of ten (10) years, unless specified otherwise
in the option agreement.

Termination.
-----------

Except as your option agreement otherwise provides, your options will
terminate following the termination of your employment, unless the options are
exercised, to the extent that they were exercisable immediately before such
termination, within the time frame permitted by your stock option agreement or,
if no time period is specified in your option agreement, within ninety (90) days
following your termination. In the event that the termination of your employment
is by reason of permanent or total disability or death, you, or your executors,
administrators, legatees or distributees of your estate, may exercise any option
held by you at the date of your employment termination, to the extent that it
was exercisable immediately before such termination, within the time frame
specified in your option agreement or, if no time is specified, for one (1) year
following such termination.

The termination of your option under the circumstances specified in this
section will result in the termination of your interests in our 1996
Supplemental Plan. In addition, your option may terminate, together with our
stock option plans and all other outstanding options issued to other employees,
following the occurrence of certain corporate events, as described below.

Exercise Price.
---------------

The Supplemental Plan Administrator determines the per share exercise price
for the shares to be issued pursuant to the exercise of the option at the time
the option is granted. For all eligible employees, the exercise price per share
of the new options will be one hundred percent (100%) of the fair market value
on the date of grant, as determined by the closing price reported by the Nasdaq
National Market on the date of grant.

-31-

Vesting and Exercise.
--------------------

Each stock option agreement specifies the term of the option and the date
when the option becomes exercisable. The terms of vesting are determined by the
Supplemental Plan Administrator. Options granted by us generally vest at a rate
of 25% of the shares subject to the option after twelve (12) months, and then
1/48th of the shares subject to the option vest each month thereafter, provided
the employee remains continuously employed by Pinnacle.

. 1/3 of the shares subject to the new option will vest immediately on
the date that the new option is granted; and

You will not receive any vesting credit for any time prior to the date that the
new options are granted, even if the old options that you tender for exchange
are vested, in whole or in part, on the Cancellation Date or would have vested,
in whole or in part, during the six (6) month and one (1) day period following
the Cancellation Date. As a result, if you elect to tender your old options for
exchange, you will not be able to purchase common stock pursuant to your new
options as early as you would have been able to purchase common stock under your
old options, had you not tendered your old options for exchange. For example:

. An employee cancels an option to purchase 3,600 shares that is 1/2
vested at the time of cancellation.

. The new option grant occurs six (6) months and one (1) day after the
cancellation.

. The new option will be 1/3rd vested at the time of grant, so the
employee is vested as to 1,200 of the shares subject to the new option
(which is 1/3rd of 3,600).

Payment of Exercise Price.
-------------------------

-32-

. cash;

. check;

. promissory note;

. certain other shares of our common stock;

. a reduction in the amount of our liability to the optionee;

. any other consideration and payment method for the issuance of shares
pursuant to the option as is permitted by applicable laws; or

. a combination of the foregoing methods.

Adjustments Upon Certain Events.
-------------------------------

In the event there is a liquidation or dissolution of Pinnacle, your
outstanding options will terminate immediately prior to the consummation of the
liquidation or dissolution. The Supplemental Plan Administrator may, however,
provide for an optionee to have the right to exercise the option until ten (10)
days prior to the liquidation or dissolution, including shares that would not
otherwise be exercisable pursuant to the option.

Per the terms of the 1996 Supplemental Plan, in the event there is a sale
of all or substantially all of our assets, or we merge with another corporation,
your options may be assumed or replaced with new options of the successor
corporation; however, if the successor corporation refuses to assume or
substitute your options, you will fully vest in and have the right to exercise
your options

-33-

as to all of the stock subject to your options, including shares that would not
otherwise be vested or exercisable.

As noted elsewhere in this Offer to Exchange, if you do not participate in
the offer and there is a sale of all or substantially all of our assets or we
merge with another company, any options you did not tender will simply be
---
treated in accordance with the terms of the stock option plan under which they
were granted. Under the 1996 Supplemental Plan, upon such events your options
will be assumed or replaced with new options of the successor corporation or
your options will terminate immediately upon the closing of the event. If your
options are assumed or substituted, you will receive a certain number of options
based on the exchange ratio determined at some point during the process of the
sale or merger. The new exercise price will also be set during the transaction.
This is unlike new options which will be granted in exchange for options
tendered pursuant to this offer. Although the number of such new options will be
affected by the exchange ratio, the exercise price for the new options will be
the fair market value of the acquiror's stock on the New Option Grant Date,
which will be no earlier than June 19, 2002. Therefore, if there is a sale or
merger of Pinnacle, options that are not tendered for exchange may receive a
lower or higher exercise price, depending on the terms of the transaction, than
those options that are tendered for exchange. In addition, the value of Pinnacle
or the successor corporation could increase as a result of an acquisition or
merger, which could result in your current options no longer being "underwater"
or result in less benefit to option holders participating in the offer. We
cannot predict the effect of an acquisition of Pinnacle or a merger on the
option price or the value of the shares and therefore urge you to take this
possibility into consideration when deciding whether to participate in the
offer.

Termination of Employment Before the New Option Grant Date.
----------------------------------------------------------

Transferability of Options.
--------------------------

New options may not be transferred, other than by will or the laws of
descent and distribution. In the event of your death, options may be exercised
by a person who acquires the right to exercise the option by bequest or
inheritance.

Registration of Option Shares.
------------------------------

Eleven million eight hundred thousand (11,800,000) shares of common stock
issuable upon exercise of options under our 1996 Supplemental Plan have been
registered under the Securities Act on registration statements on Form S-8 filed
with the SEC. All the shares issuable upon exercise of all new options to be
granted before the offer will be registered under the Securities Act. Unless you

-34-

are one of our affiliates, you will be able to sell your option shares free of
any transfer restrictions under applicable U.S. securities laws.

Income Tax Consequences.

You should refer to Sections 14 through 18 of this Offer to Exchange for a
discussion of the income tax consequences on tax residents of the United States,
France, Germany, Japan and the United Kingdom of the new options and the options
tendered for exchange, as well as the consequences of accepting or rejecting the
new options under this offer to exchange. If you are living or working in the
United States, but are also subject to the tax laws in another country, you
should be aware that there may be other tax and social insurance consequences
which may apply to you; we strongly recommend that you consult with your own
advisors to discuss the consequences to you of this transaction.

Supplemental Stock Option Plan are eligible for exchange pursuant to the Offer
to Exchange.

There have been no transactions in options to purchase our shares or in our
shares which were effected during the 60 days prior to November 5, 2001 by
Pinnacle or, to our knowledge, by any executive officer, director or affiliate
of Pinnacle.

12. Status of options acquired by us in the offer; accounting consequences
----------------------------------------------------------------------
of the offer.
------------

Options issued under the 1996 Plan and the 1996 Supplemental Plan that we
acquire through the offer will be cancelled and the shares subject to those
options will be returned to the pool of shares available for grants of new
options under the 1996 Plan or the 1996 Supplemental Plan, as applicable. To the
extent these shares are not fully reserved for issuance upon exercise of the new
options to be granted in connection with the offer, the shares will be available
for future awards to employees and other eligible 1996 Plan and 1996
Supplemental Plan participants without further shareholder action, except as
required by applicable law or the rules of the Nasdaq National Market
or any other securities quotation system or any stock exchange on which our
shares are then quoted or listed.

We believe that we will not incur any compensation expense solely as a
result of the transactions contemplated by the offer because:

. we will not grant any new options until a business day that is at
least six (6) months and one (1) day after the date that we accept and
cancel options tendered for exchange, and

. the exercise price of all new options will at least equal the market
value of the shares of common stock on the date we grant the new
options.

13. Legal matters; regulatory approvals.
-----------------------------------

We are not aware of any license or regulatory permit that appears to be
material to our business that might be adversely affected by our exchange of
options and issuance of new options as contemplated by the offer, or of any
approval or other action by any government or governmental, administrative or
regulatory authority or agency, domestic or foreign, that would be required for
the acquisition or ownership of our options as contemplated herein. Should any
such approval or other action be required, we presently contemplate that we will
seek such approval or take such other action. We cannot assure you that any such
approval or other action, if needed, could be obtained or what the conditions
imposed in connection with such approvals would entail or whether the failure to
obtain any such approval or other action would result in adverse consequences to
our business. Our obligation under the offer to accept tendered options for
exchange and to issue new options for tendered options is subject to the
conditions described in Section 7 of this Offer to Exchange.

If we are prohibited by applicable laws or regulations from granting new
options during the period beginning immediately after the date we expect to
grant the new options (expected to be June 19, 2002), we will not grant any new
options. We are unaware of any such prohibition at this time, and we will use
reasonable efforts to effect the grant, but if the grant is prohibited
throughout the period we will not grant any new options and you will not get any
other consideration for the options you tendered.

14. Material U.S. Federal Income Tax Consequences.
----------------------------------------------

The following is a general summary of the material U.S. federal income tax
consequences of the exchange of options pursuant to the offer. This discussion
is based on the Internal Revenue Code of 1986, as amended, its legislative
history, Treasury Regulations thereunder and administrative and judicial
interpretations thereof as of the date of the offer, all of which are subject to
change, possibly on a retroactive basis. This summary does not discuss all of
the tax consequences that may be relevant to you in light of your particular
circumstances, nor is it intended to be applicable in all respects to all
categories of option holders. If you are living or working in the United States,
but are also subject to the tax laws in another country, you should be aware
that there may be other tax and social insurance consequences which may apply to
you. We strongly recommend that you consult your own advisors to discuss the
consequences to you of participating in the offer.

-37-

Option holders who exchange outstanding options for new options should not
be required to recognize income for federal income tax purposes at the time of
the exchange. We believe that the exchange will be treated as a non-taxable
exchange. We advise all option holders considering exchanging their options to
meet with their own tax advisors with respect to the federal, state, local and
foreign tax consequences of participating in the offer.

Incentive Stock Options
-----------------------

Under current law, an option holder will not realize taxable income upon
the grant of an incentive stock option under our 1996 Plan. In addition, an
option holder generally will not realize taxable income upon the exercise of an
incentive stock option. However, an option holder's alternative minimum taxable
income will be increased by the amount that the aggregate fair market value of
the shares underlying the option, which is generally determined as of the date
of exercise, exceeds the aggregate exercise price of the option. Except in the
case of an option holder's death or disability, if an option is exercised more
than three (3) months after the option holder's termination of employment, the
option ceases to be treated as an incentive stock option and is subject to
taxation under the rules that apply to nonstatutory stock options.

If an option holder sells the option shares acquired upon exercise of an
incentive stock option, the tax consequences of the disposition depend upon
whether the disposition is qualifying or disqualifying. The disposition of the
option shares is qualifying if it is made:

. at least two (2) years after the date the incentive stock option was
granted, and

. at least one (1) year after the date the incentive stock option was
exercised.

If the disposition of the option shares is qualifying, any excess of the
sale price of the option shares, over the exercise price of the option will be
treated as long-term capital gain taxable to the option holder at the time of
the sale. Any such capital gain will be taxed at the long-term capital gain rate
in effect at the time of sale. If the disposition is not qualifying, which we
refer to as a "disqualifying disposition," the excess of the fair market value
of the option shares on the date the option was exercised, over the exercise
price will be taxable income to the option holder at the time of the
disposition.

Of that income, the amount up to the excess of the fair market value of the
shares at the time the option was exercised over the exercise price will be
ordinary income for income tax purposes and the balance, if any, will be
long-term or short-term capital gain, depending upon whether or not the shares
were sold more than one (1) year after the option was exercised.

Unless an option holder engages in a disqualifying disposition, we will not
be entitled to a deduction with respect to an incentive stock option. If an
option holder engages in a disqualifying disposition, we will be entitled to a
deduction equal to the amount of compensation income taxable to the option
holder.

-38-

If you tender incentive stock options and those options are accepted for
exchange, the new options will be granted as incentive stock options to the
maximum extent they qualify. For options to qualify as incentive stock options,
the value of shares subject to options that first become exercisable in any
calendar year cannot exceed $100,000, as determined using the option exercise
price. The excess value is deemed to be a nonstatutory stock option.

You should note that if the new options have a higher exercise price than
some or all of your current options, the new options may exceed the limit for
incentive stock options. You should note that there is a risk that any incentive
stock options you have may be affected, even if you do not participate in the
exchange. We do not believe that our offer to you will change any of the terms
of your eligible incentive stock options if you do not accept the offer. We
believe that you will not be subject to current U.S. federal income tax if you
do not elect to participate in the option exchange program. We also believe that
the option exchange program will not change the U.S. federal income tax
treatment of subsequent grants and exercises of your incentive stock options
(and sales of shares acquired upon exercises of such options) if you do not
participate in this offer to exchange options. However, the IRS may characterize
this offer to exchange options as a "modification" of those incentive stock
options, even if you decline to participate. In 1991, the IRS issued a private
letter ruling in which another company's option exchange program was
characterized as a "modification" of all of the incentive stock options that
could be exchanged. This does not necessarily mean that our offer to exchange
options will be viewed the same way. Private letter rulings given by the IRS
contain the IRS's opinion regarding only the specific facts presented by a
specific person or company. The person or company receiving the letter may rely
on it, but no other person or company may rely on the letter ruling, nor may
they assume the same opinion would apply to their situation, even if the facts
at issue are similar. While such letters do not provide certainty, they may
indicate how the IRS will view a similar situation. We therefore do not know if
the IRS will assert the position that our offer constitutes a "modification" of
incentive stock options eligible for tender. A successful assertion by the IRS
of this position could extend the options' holding period to qualify for
favorable tax treatment. Accordingly, to the extent you dispose of your
incentive stock option shares prior to the lapse of the new extended holding
period, your incentive stock option could be taxed similarly to a nonstatutory
stock option.

Nonstatutory Stock Options
--------------------------

Under current law, an option holder will not realize taxable income upon
the grant of an option which is not qualified as an incentive stock option, also
referred to as a nonstatutory stock option, under either the 1996 Plan or the
1996 Supplemental Plan. However, when an option holder exercises the option, the
difference between the exercise price of the option, and the fair market value
of the shares subject to the option on the date of exercise will be compensation
income taxable to the option holder.

We will be entitled to a deduction equal to the amount of compensation
income taxable to the option holder if we comply with eligible reporting
requirements.

-39-

We recommend that you consult your own tax advisor with respect to the
federal, state, local and foreign tax consequences of participating in the
offer, as the tax consequences to you of participation in the offer are
dependent on your individual tax situation.

15. Material Tax Consequences for Employees Who are Tax Residents in
-----------------------------------------------------------------------
France.
------

The following is a general summary of the income tax and social
contributions consequences of the exchange of options under the offer for French
tax residents. This discussion is based on French tax law as of the date of the
offer, which is subject to change, possibly on a retroactive basis. This summary
does not discuss all of the tax consequences that may be relevant to you in
light of your particular circumstances, nor is it intended to be applicable in
all respects to all categories of option holders. You should be sure to consult
with your personal tax advisor to discuss the tax consequences which may be
particular to you.

You will not be subject to tax when the new option is granted.

When you exercise the option, you will be subject to tax on the spread gain
equal to the difference between the option price and the fair market value of
stock acquired on the exercise date. This spread gain is treated as a salary and
subject to the progressive rates of French income tax.

Furthermore, this spread gain is subject to social contributions (plus CSG
at a rate of 7.5% and CRDS at a rate of 0.5%) on the date of exercise as a
salary income which will be withheld from your payslip.

When you sell the shares, the capital gain (i.e. difference between the
sale price of the stock and the fair market value upon the exercise date), if
any, is taxed at a flat rate of 26% (including CSG, CRDS and 2% social tax),
provided that the annual gross proceeds from the sale of stocks made during the
calendar year exceed FRF 50,000 for 2001 tax year. Should the gross proceeds be
below that limit, the capital gain would be tax-free.

Please consult with your personal tax advisor for additional information
regarding the tax treatment of options in France.

16. Material Tax Consequences for Employees Who are Tax Residents in
----------------------------------------------------------------
Germany.
-------

The following is a general summary of the tax consequences of the exchange
of options under the offer for German tax residents. This discussion is based on
the interpretation of general German tax law as of the date of the offer, which
is subject to change, possibly on a retroactive basis. There are no specific
rules regarding the exchange of stock options. This summary does not discuss all
of the tax consequences that may be relevant to you in light of your particular
circumstances, nor is it intended to be applicable in all respects to all
categories of option holders. You should be sure to consult with your personal
tax advisor to discuss the tax consequences which may be particular to you.

-40-

You will not be subject to tax when the new option is granted. When you
exercise the option, you will be subject to income tax on the difference between
the fair market value of the shares on the date of exercise and the exercise
price. The income recognized would be compensation to you and would be subject
to German wage tax withholding as a one-time payment (Einmalbezug) in the month
of exercise whereby the withholding tax has to be submitted to the corporate tax
office of Pinnacle in Germany.

When you sell the shares, you will not be subject to tax on any additional
gain provided that:

(i) you have held the stock for more than twelve (12) months;

(ii) you have not, during the last five years, held one percent (1%)
or more of the stated capital of Pinnacle; and

(iii) the stock is not held as a business asset.

Effective January 1, 2001, the ten percent (10%) limit was lowered to one
percent (1%) such that in order to satisfy the foregoing conditions, you cannot
have held one percent (1%) or more of the stated capital of Pinnacle.
Consequently, you normally will not be subject to tax at the time of sale on the
additional gains if you hold the shares for more than twelve (12) months.

As of January 1, 2001 for foreign corporations and January 1, 2002 for
German corporations only fifty percent (50%) of the capital gains will be
taxable if above-mentioned conditions for tax-free capital gains are not met.
Please consult with your personal tax advisor for additional information
regarding the tax treatment of options in Germany.

17. Material Tax Consequences for Employees Who are Tax Residents in
----------------------------------------------------------------
Japan.
-----

The following is a general summary of the tax consequences of the exchange
of options under the offer for Japanese tax residents. This discussion is based
on Japanese tax law as of the date of the offer, which is subject to change,
possibly on a retroactive basis. This summary does not discuss all of the tax
consequences that may be relevant to you in light of your particular
circumstances, nor is it intended to be applicable in all respects to all
categories of option holders. You should be sure to consult with your personal
tax advisor to discuss the tax consequences which may be particular to you.

You will not be subject to tax when the new option is granted. When you
exercise the option, you will be subject to income tax on the difference between
the fair market value of the shares on the date of exercise and the exercise
price. Your income will likely be treated as "remuneration income" and will be
taxed at your marginal tax rate.

When you sell the shares, you will be subject to tax at a flat rate of 26%
(i.e., a 20% national income tax and a 6% local inhabitants tax). If you sell
your shares through an authorized

-41-

stockbroker or bank in Japan and submit an election return form, you may elect
to have the broker withhold 1.05% of the total amount received (regardless of
the gain) from selling your shares. If you make this election, the deemed gain
will be 5.25% of the proceeds from the sale of the shares. The deemed gain will
only be subject to the 20% national income tax; the 6% local inhabitants tax
would not apply. Please note that, although this 1.05% taxation method was
scheduled to be abolished as of April 1, 2001 under the 2000 tax legislation, it
was extended until April 1, 2003. Therefore, you may elect to be taxed at 1.05%
of the total proceeds until March 31, 2003.

Please consult with your personal tax advisor for additional information
regarding the tax treatment of options in Japan.

18. Material Tax Consequences for Employees Who are Tax Residents in the
-----------------------------------------------------------------------
United Kingdom.
--------------

The following is a general summary of the income tax and National Insurance
Contributions ("NIC") consequences of the exchange of options pursuant to the
offer for U.K. tax residents. This discussion is based on the U.K. tax law as of
the date of the offer, which is subject to change, possibly on a retroactive
basis. This summary does not discuss all of the tax consequences that may be
relevant to you in light of your particular circumstances, nor is it intended to
be applicable in all respects to all categories of option holders. You should be
sure to consult with your personal tax advisor to discuss the tax consequences
which may be particular to you.

The original options granted to you by Pinnacle were granted under a
non-approved stock option plan. With a non-approved stock option, income tax
liability arises on the exercise of the option based on the difference between
the fair market value of the shares on the date of exercise and the exercise
price. In addition, since April 6, 1999, a liability to pay both employer's
Secondary Class 1 and employee Class 1 NIC arises on the gain realized at
exercise, calculated effectively in the same manner as for income tax. The
employee charge will only arise if your earnings do not already exceed the
maximum limit for NIC purposes. When you sell your shares, you may be subject to
capital gains tax.

Like the old option, the new option will also be granted under an
unapproved share scheme. You will be liable for any employee Class 1 NIC
Payments that arise in connection with the exercise, assignment, release or
cancellation of the option. Pinnacle will be responsible for paying any
employer's Secondary Class 1 NIC liabilities that arise in connection with the
assignment, release or cancellation of the option.

-42-

You will not be subject to tax when the new unapproved option is granted.

You will be subject to income tax when you exercise the option on the
difference between the fair market value of the shares on the date of exercise
and the exercise price. You will also be liable to pay the employee's NICs on
the proceeds at exercise if your earnings do not already exceed the maximum
limit for NIC purposes - (pound)575 per week for the U.K. tax year April 6, 2001
to April 5, 2002.

When you sell your shares, you may be subject to capital gains tax. The tax
is due on any increase in the value of the stock between the date on which you
exercised your options and the date on which you sell the shares. Any capital
gains tax you may owe is subject to an annual personal exemption (currently
(pound)7,500 for the U.K. tax year April 6, 2001 to April 5, 2002) and to taper
relief calculated with reference to the period of time during which you held the
shares.

Please consult with your personal tax advisor for additional information
regarding the tax treatment of options in the United Kingdom.

19. Extension of offer; termination; amendment.
------------------------------------------

We expressly reserve the right, in our discretion, at any time and from
time to time, and regardless of whether or not any event listed in Section 7 of
this Offer to Exchange has occurred or is deemed by us to have occurred, to
extend the period of time during which the offer is open and thereby delay the
acceptance for exchange of any options by giving oral or written notice of such
extension to the option holders or making a public announcement thereof.

We also expressly reserve the right, in our reasonable judgment, prior to
the expiration date to terminate or amend the offer and to postpone our
acceptance and cancellation of any options tendered for exchange upon the
occurrence of any of the events listed in Section 7 of this Offer to Exchange,
by giving oral or written notice of such termination or postponement to you or
by making a public announcement thereof. Our reservation of the right to delay
our acceptance and cancellation of options tendered for exchange is limited by
Rule 13e-4(f)(5) promulgated under the Exchange Act, which requires that we must
pay the consideration offered or return the options tendered promptly after
termination or withdrawal of a tender offer.

Subject to compliance with applicable law, we further reserve the right, in
our discretion, and regardless of whether any event listed in Section 7 of this
Offer to Exchange has occurred or is deemed by us to have occurred, to amend the
offer in any respect, including, without limitation, by

-43-

decreasing or increasing the consideration offered in the offer to option
holders or by decreasing or increasing the number of options being sought in the
offer.

Amendments to the offer may be made at any time and from time to time by
public announcement of the amendment. In the case of an extension, the amendment
must be issued no later than 6:00 a.m., Pacific Standard Time, on the next
business day after the last previously scheduled or announced expiration date.
Any public announcement made through the offer will be disseminated promptly to
option holders in a manner reasonably designated to inform option holders of the
change. Without limiting the manner in which we may choose to make a public
announcement, except as required by applicable law, we have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by making a press release to the Dow Xxxxx News Service.

If we materially change the terms of the offer or the information
concerning the offer, or if we waive a material condition of the offer, we will

Statements of Pinnacle, as filed in Pinnacle's Annual Report on Form 10-K for
our fiscal year ended June 30, 2000, filed with the SEC on September 26, 2001
(file number 000-24784). More complete financial information may be obtained by
accessing our public filings with the SEC by following the instructions in
Section 21 of this Offer to Exchange.

23. Miscellaneous.
-------------

This Offer to Exchange and our SEC reports referred to above include
"forward-looking statements." When used in this Offer to Exchange, the words
"anticipate," "believe," "estimate," "expect," "intend" and "plan" as they
relate to Pinnacle or our management are intended to identify these
forward-looking statements. All statements by us regarding our expected future
financial position and operating results, our business strategy, our financing
plans and expected capital requirements, forecasted trends relating to our
services or the markets in which we operate and similar matters are
forward-looking statements. The documents we filed with the SEC, including our
annual report on Form 10-K filed on September 26, 2001 and our quarterly report
on Form 10-Q filed November 14, 2001, discuss some of the risks that could cause
our actual results to differ from those contained or implied in the
forward-looking statements. These risks include, but are not limited to:

. Our quarterly and annual operating results have varied significantly
in the past and may continue to fluctuate because of a number of
factors, many of which are out of our control.

. Deteriorating market conditions and continued economic uncertainty
could materially adversely impact our revenues and growth rate.

. Our revenues, particularly in the Broadcast and Professional Solutions
Division, are increasingly becoming dependent on large broadcast
system sales to a few significant customers. Our business and
financial condition may be materially adversely affected if sales are
delayed or not completed within a given quarter or if any of our
significant customers terminate their relationship, or contracts, with
us, modify their requirements

-46-

that may delay installation and revenue recognition, or
significantly reduce the amount of business they do with us.

. We incurred losses in fiscal 2001 and expect to continue to incur
losses in fiscal 2002.

. Quarter-end discounting, resulting from customers delaying
negotiations until quarter-end in an effort to improve their
ability to obtain more favorable pricing terms, may delay sales
transactions.

. Our goodwill and other intangible assets may become impaired,
rendering their carrying amounts unrecoverable, and, as a result,
we may be required to record a substantial impairment charge that
will adversely affect our financial position.

. We are dependent on contract manufacturers and single or limited
source suppliers for our components. If these manufacturers and
suppliers do not meet our demand, either in volume or quality,
our business and financial condition could be materially harmed.

. We must retain key employees to be competitive.

. We incurred negative cash flow in fiscal 2001 and expect to
continue to incur negative cash flow in fiscal 2002, and our
financial condition and results of operations may be adversely
affected as a result.

. If we experience difficulty in developing and installing our
Vortex News systems, our financial position and results of
operations could be harmed.

. Any failure to successfully integrate the businesses we have
acquired could negatively impact us.

. Our stock price may be volatile.

. If our products do not keep pace with the technological
developments in the rapidly changing video post-production
equipment industry, our business may be materially adversely
affected.

. If we do not compete effectively, our business will be harmed.

. We rely heavily on dealers and OEM's to market, sell and
distribute our products. As a result, we rely heavily on the
success of these resellers. If these resellers do not succeed in
effectively distributing our products our financial performance
will be negatively affected.

. We may be adversely affected if a third party sues us or if we
decide to xxx a third party regarding intellectual property
rights.

-47-

. Excess or obsolete inventory, and overdue or uncollectible accounts
receivables, could weaken our cash flow, harm our financial condition
and results of operations and cause our stock price to fall.

. We may be unable to protect our proprietary information and procedures
effectively.

. Because we sell products internationally, we are subject to
additional risks.

. We rely on a continuous power supply to conduct our operations, and
California's current energy crisis could disrupt our operations and
increase our expenses.

For a complete description of the above-mentioned risks, please see the SEC
filings referred to in Section 22 of this Offer to Exchange, entitled
"Additional Information," above.

We are not aware of any jurisdiction where the making of the offer is not
in compliance with applicable law. If we become aware of any jurisdiction where
the making of the offer is not in compliance with any valid applicable law, we
will make a good faith effort to comply with such law. If, after such good faith
effort, we cannot comply with such law, the offer will not be made to, nor will
tenders be accepted from or on behalf of, the option holders residing in such
jurisdiction.

We have not authorized any person to make any recommendation on our behalf
as to whether you should tender or not tender your options through the offer.
You should rely only on the information in this document or documents to which
we have referred you. We have not authorized anyone to give you any information
or to make any representations in connection with the offer other than the
information and representations contained in this Offer to Exchange, the
memorandum from Xxxx X. Xxxxxxx dated November 16, 2001, the Election Form and
the Notice to Withdraw from the Offer. If anyone makes any recommendation or
representation to you or gives you any information, you must not rely upon that
recommendation, representation or information as having been authorized by us.
