                             PORTOLA PACKAGING, INC.
                             1994 STOCK OPTION PLAN
                            ADOPTED NOVEMBER 18, 1994
                  (AMENDED NOVEMBER 6, 1996 AND MARCH 25, 1999)



1. PURPOSE AND TYPES OF OPTIONS. This 1994 Stock Option Plan (the "PLAN") is
intended to increase the incentives of, and encourage stock ownership by,
employees and consultants (including members of the Company's Board of Directors
who are not employees of the Company) providing services to Portola Packaging,
Inc., a Delaware corporation (the "COMPANY"), or to corporations which are or
become subsidiary corporations of the Company. The term "subsidiary
corporations" as used in this Plan shall have the meaning specified in Section
4.2 hereof. The Plan is intended to provide such employees and consultants with
a proprietary interest (or to increase their proprietary interest) in the
Company, and to encourage them to continue their employment or engagement by the
Company or its subsidiaries. Options granted pursuant to the Plan, at the
discretion of the Company's Board of Directors ("BOARD"), may be either
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended ("INTERNAL REVENUE CODE"), or options that do
not so qualify as incentive stock options and which are referred to herein as
non-qualified stock options.


2. STOCK. The capital stock subject to the Plan shall be shares of the Company's
authorized but unissued Common Stock ("COMMON STOCK") or treasury shares of
Common Stock. The maximum aggregate number of shares of Common Stock which may
be issued under the Plan is Three Million Five Hundred Thousand (3,500,000),
subject to adjustments pursuant to Section 8 hereof. In the event that any
outstanding option under the Plan shall expire by its terms or is otherwise
terminated for any reason (or if shares of Common Stock of the Company which are
issued upon exercise of an option granted hereunder are subsequently reacquired
by the Company pursuant to contractual rights of the Company under the
particular stock option agreement), the shares of the Common Stock allocated to
the unexercised portion of such option (or the shares so reacquired by the
Company pursuant to the terms of the stock option agreement) shall again become
available to be made subject to options granted under the Plan. Notwithstanding
any other provision of this Plan, the aggregate number of shares of Common Stock
subject to outstanding options granted under this Plan at any given time, plus
the aggregate number of shares which have been issued upon exercise of all
options granted under this Plan and which remain outstanding, shall never be
permitted to exceed the maximum number of shares specified above in this Section
2 (subject to adjustments under Section 8).


3. ADMINISTRATION. The Plan shall be administered by the Board. Any action by
the Board with respect to the administration of the Plan shall be taken by the
vote of a majority of a quorum of its members present at a duly held meeting or
without a meeting by unanimous written consent of all directors. The
interpretation and construction by the Board of any provision of this Plan, or
of any option granted pursuant hereto, shall be final, binding and conclusive.
No member of the Board shall be liable to the Company or to any subsidiary or
parent corporation, or to the holder of any

Portola Packaging, Inc.
1994 Stock Option Plan
Page 2



option granted hereunder for any action, inaction, determination or
interpretation made in good faith with respect to the Plan or any transaction
hereunder. Notwithstanding the foregoing, the Board shall have the authority to
delegate some or all of its duties to administer this Plan and to exercise its
powers hereunder to a committee ("COMMITTEE") appointed by the Board. For
purposes of this Plan, all references herein to "Board" shall be deemed to also
refer to any such Committee. Any Committee charged with administration of the
Plan shall have all the powers and protections provided to the Board under this
Plan until the Board shall revoke or restrict such powers or protections. More
specifically, the Board, subject to compliance with the remaining provisions of
this Plan, shall have the following powers and authority (which listing is
provided by way of example and is not intended to be comprehensive or limiting
to the extent of powers not included):

         3.1 SELECTION OF OPTIONEES. To determine the persons providing services
to the Company to whom, and the time or times at which, options to purchase
Common Stock of the Company shall be granted;

         3.2 NUMBER OF OPTION SHARES. To determine the number of shares of
Common Stock to be subject to options granted to each such person;

         3.3 EXERCISE PRICE. To determine the price to be paid for the shares of
Common Stock upon the exercise of each option;

         3.4 TERM AND EXERCISE SCHEDULE. To determine the term and the exercise
schedule of each option;

         3.5 OTHER TERMS OF OPTIONS. To determine the terms and conditions of
each stock option agreement (which need not be identical) entered into between
the Company and any person to whom the Board determines to grant an option;

         3.6 INTERPRETATION OF PLAN. To interpret the Plan and to prescribe,
amend and rescind rules and regulations relating to the Plan;

         3.7 AMENDMENT OF OPTIONS. With the consent of the holder thereof, to
modify or amend any option granted under the Plan; and

         3.8 GENERAL AUTHORITY. To take such actions and make such
determinations deemed necessary or advisable by the Board for the administration
of the Plan, subject to complying with the Plan and with applicable legal
requirements.

4. ELIGIBILITY AND AWARD OF OPTIONS.

         4.1 AUTHORITY TO GRANT AND ELIGIBILITY. The Board shall have full and
final authority, in its discretion and at any time and from time to time during
the term of this Plan, to grant or authorize the granting of options to such
officers, directors and employees of, and consultants retained by, the Company
or its subsidiary corporations as it may select, and to determine the number of
shares of Common Stock to be subject to each option. Any individual who is
eligible to receive a stock option under this Plan shall be eligible to hold
more than one option at any given time, in the discretion of the Board. The
Board shall have full and final authority in its discretion to determine, in the
case of employees (including employees that are officers or directors), whether
such options shall be incentive stock options or non-qualified stock options;
however, no incentive stock option may be granted to any person who is not a
bona fide employee of the Company or of a subsidiary corporation of the Company.
Persons selected by the Board who are prospective employees of, or consultants
to be retained by, the Company or its subsidiaries, including members of the
Board, shall be eligible to receive non-qualified stock options; provided,
however, that in the case of such prospective employment or other engagement,
the exercisability of such options shall be subject in each case to such person
in fact becoming an employee or consultant, as applicable, of the Company or its
subsidiaries.

         4.2 CERTAIN RESTRICTIONS APPLICABLE TO STOCK OPTIONS. No stock option
shall be granted to any employee who, at the time such option is granted, owns
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of outstanding capital stock of the Company, or of any parent
corporation or subsidiary corporation of the Company, unless the exercise price
(as provided in Section 5.1 hereof) is not less than one hundred ten percent
(110%) of the fair market value of the Common Stock on the date the option is
granted and, if an incentive stock option, the period within which the option
may be exercised (as provided in Section 5.2 hereof) does not exceed five (5)
years from the date the option is granted. As used in this Plan, the terms
"parent corporation" and "subsidiary corporation" shall have the meanings set
forth in Sections 424(e) and (f), respectively, of the Internal Revenue Code.
For purposes of this Section 4.2, in determining stock ownership, an employee
shall be considered as owning the voting capital stock owned, directly or
indirectly, by or for his or her brothers and sisters, spouse, ancestors and
lineal descendants. Voting capital stock owned, directly or indirectly, by or
for a corporation, partnership, estate or trust shall be considered as being
owned proportionately by or for its stockholders, partners or beneficiaries, as
applicable. Additionally, for purposes of this Section 4.2, outstanding capital
stock shall include all capital stock actually issued and outstanding
immediately after the grant of the option to the employee. Outstanding capital
stock shall not include capital stock authorized for issue under outstanding
options held by the employee or by any other person. Additionally, the aggregate
fair market value (determined as of the date an option is granted) of the Common
Stock with respect to which incentive stock options granted are exercisable for
the first time by an employee during any one calendar year (under this Plan and
under all other incentive stock option plans of the Company and of any parent or
subsidiary corporation) shall not


<PAGE>   4


Portola Packaging, Inc.
1994 Stock Option Plan
Page 4



exceed One Hundred Thousand Dollars ($100,000). If the aggregate fair market
value (determined as of the date an option is granted) of the Common Stock with
respect to which incentive stock options granted are exercisable for the first
time by an employee during any calendar year exceeds One Hundred Thousand
Dollars ($100,000), the options for the first One Hundred Thousand Dollars
($100,000) worth of shares of Common Stock to become exercisable in such
calendar year shall be incentive stock options and the options for the amount in
excess of One Hundred Thousand Dollars ($100,000) that become exercisable in
that calendar year shall be non-qualified stock options. In the event that the
Internal Revenue Code or the regulations promulgated thereunder are amended
after the effective date of the Plan to provide for a different limit on the
fair market value of shares of Common Stock permitted to be subject to incentive
stock options, such different limit shall be automatically incorporated herein
and shall apply to options granted after the effective date of such amendment.

         4.3 DATE OF GRANT. The date on which an option is granted shall be
stated in each option agreement and shall be the date of the Board's
authorization of such grant or such later date as may be set by the Board at the
time such grant is authorized.


5. TERMS AND PROVISIONS OF OPTION AGREEMENTS. Each option granted under the Plan
shall be evidenced by a stock option agreement between the person to whom the
option is granted and the Company. Each such agreement shall be subject to the
following terms and conditions, and to such other terms and conditions not
inconsistent herewith as the Board may deem appropriate in each case:

         5.1 EXERCISE PRICE. The price to be paid for each share of Common Stock
upon the exercise of an option shall be determined by the Board at the time the
option is granted; provided however, that (1) no non-qualified stock option
shall have an exercise price less than eighty-five percent (85%) of the fair
market value of the Common Stock on the date the option is granted; (2) no
incentive stock option shall have an exercise price less than one hundred
percent (100%) of the fair market value of the Common Stock on the date the
option is granted and (3) all stock options granted to the ten percent (10%)
stockholders shall have the exercise price set at not less than one hundred ten
percent (110%) of fair market value at the date of the grant, as provided in
Section 4.2 hereof. For all purposes of this Plan, the fair market value of the
Common Stock on any particular date shall be the closing price on the trading
day next preceding that date on the principal securities exchange on which the
Company's Common Stock is listed, or, if such Common Stock is not then listed on
any securities exchange, the fair market value of the Common Stock on such date
shall be the mean of the closing bid and asked prices as reported by the
National Association of Securities Dealers, Inc. Automated Quotation System
("NASDAQ") on the trading day next preceding such date. In the event that the
Company's Common Stock is neither listed on a securities exchange nor quoted by
NASDAQ, then the Board shall in good faith determine the fair market value of
the Company's Common Stock on such date, with such determination being based
upon past arms-length


<PAGE>   5


Portola Packaging, Inc.
1994 Stock Option Plan
Page 5



sales by the Company of its equity securities and other factors considered
relevant in determining the Company's fair value; provided, however, that any
individual form of option agreement may provide for alternative means of
valuation for the purpose of repurchase at fair market value of shares acquired.

         5.2 TERM OF OPTIONS. The period or periods within which an option may
be exercised shall be determined by the Board at the time the option is granted,
but no exercise period shall exceed ten (10) years from the date the option is
granted (or five (5) years in the case of any incentive stock option granted to
a ten percent (10%) stockholder as described in Section 4.2 hereof).

         5.3 EXERCISABILITY. Stock options granted under this Plan shall be
exercisable at such future time or times (or may be fully exercisable upon
grant), whether or not in installments, as shall be determined by the Board and
provided in the form of stock option agreement. Notwithstanding any other
provisions of this Plan, no option may be exercised after the expiration of ten
(10) years from the date of grant.

         5.4 METHOD OF PAYMENT FOR COMMON STOCK UPON EXERCISE. Except as
otherwise provided in the applicable stock option agreement (subject to the
limitations of this Plan), the exercise price for each share of Common Stock
purchased under an option shall be paid in full in cash at the time of purchase
(or by check acceptable to the Board). At the discretion of the Board, the stock
option agreement may provide for (or the Board may permit) the exercise price to
be paid by one or more of the following additional alternative methods: (i) the
surrender of shares of the Company's Common Stock, in proper form for transfer,
owned by the person exercising the option and having a fair market value on the
date of exercise equal to the exercise price, provided that such shares (a) have
been owned by the optionee for more than six (6) months and have been paid for
within the meaning of Rule 144 under the Securities Act of 1933, as amended (the
"SECURITIES ACT") (and, if such shares were purchased from the Company by use of
a promissory note, such note has been fully paid with respect to such shares) or
(b) were obtained by the optionee in the public market, (ii) to the extent
permitted under the applicable provisions of the Delaware General Corporation
Law, the delivery by the person exercising the option of a full recourse
promissory note executed by such person, bearing interest at a per annum rate
which is not less than the "test rate" as set by the regulations promulgated
under Sections 483 or 1274, as applicable, of the Internal Revenue Code and as
in effect on the date of exercise, or (iii) any combination of cash, shares of
Common Stock or promissory notes, so long as the sum of the cash so paid, plus
the fair market value of the shares of Common Stock so surrendered and the
principal amounts of the promissory notes so delivered, is equal to the
aggregate exercise price. Without limiting the generality of the foregoing, the
form of option agreement may provide (or the Board may otherwise permit, in its
discretion) that the option be exercised through a "net issue" exercise
procedure (cash-less exercise), whereby the optionee may elect to receive shares
of the Company's Common Stock having an aggregate fair market value at the date
of exercise equal to the net value of the portion of the option


<PAGE>   6


Portola Packaging, Inc.
1994 Stock Option Plan
Page 6



so exercised as of the exercise date. For purposes of the foregoing, the net
value of any option (or portion thereof) as of such exercise date shall be equal
to the aggregate fair market value of the shares subject to the option (or
portion thereof being exercised) less the aggregate exercise price of the option
(or portion thereof). In such event the Company shall issue to the optionee a
number of shares of the Company's Common Stock having a fair market value as of
the date of exercise equal to the net value of the option (or portion thereof
being exercised). No share of Common Stock shall be issued under any option
until full payment therefor has been made in accordance with the terms of the
stock option agreement (and in compliance with the Plan). Notwithstanding the
foregoing, an Option may not be exercised by surrender to the Company of shares
of the Company's Common Stock to the extent such surrender of stock would
constitute a violation of the provisions of any law, regulation and/or agreement
restricting the redemption of the Company's Common Stock. Any promissory note
accepted upon the exercise of an option from a person who is a consultant or
other independent contractor retained by the Company or any subsidiary shall be
adequately secured by collateral other than the shares of the Common Stock
acquired upon such exercise. Additionally, if permitted by the form of stock
option agreement, or at the Board's discretion, any such promissory note may
permit the payment of principal and interest accruing thereunder by surrender of
shares of the Company's Common Stock, in proper form for transfer, and having a
fair market value on the date of payment and surrender equal to the dollar
amount to be applied to principal and accrued interest thereunder.

         5.5 NON-ASSIGNABILITY. No stock option granted under the Plan shall be
assignable or transferable by an optionee except by will or the laws of descent
and distribution and each stock option granted under the Plan shall be
exercisable only by the optionee during his or her lifetime.

         5.6 TERMINATION OF EMPLOYMENT PROVISIONS APPLICABLE TO STOCK OPTIONS.
Each stock option agreement shall comply with the following provisions relating
to early termination of the option based upon termination of the employee's
employment with the Company:

                  5.6.1 DEATH. Upon the death of an employee of the Company, any
stock option which such employee holds may be exercised to the extent it was
exercisable at the date of death, within such period after the date of death as
the Board shall prescribe in the stock option agreement (but not less than six
(6) months nor more than twelve (12) months after death), by the employee's
representative or by the person entitled thereto under the employee's will or
the laws of intestate succession. If the option is not so exercised in
accordance with the foregoing, it shall terminate upon the expiration of such
prescribed period.

                  5.6.2 DISABILITY. If the employee's employment with the
Company is terminated because of the disability of the employee, any stock
option which the employee holds may be exercised by the employee within such
period after the date of termination of employment resulting from such
disability (but not less than six (6) months nor more than twelve (12) months
after termination by reason of disability) as the Board shall prescribe in the
stock option agreement, to the


<PAGE>   7


Portola Packaging, Inc.
1994 Stock Option Plan
Page 7



extent such option would otherwise be exercisable during such period. If the
option is not so exercised in accordance with the foregoing, it shall terminate
upon the expiration of such prescribed period unless the employee dies prior
thereto, in which event the employee shall be treated as though his or her death
occurred on the date of termination resulting from such disability and the
provisions of Section 5.6.1 hereof shall apply.

                  5.6.3 TRANSFER TO RELATED CORPORATION. In the event that an
employee of the Company leaves the employ of the Company to become an employee
of any parent or subsidiary corporation of the Company, or if the employee
leaves the employ of any such parent or subsidiary corporation to become an
employee of the Company or of another parent or subsidiary corporation, such
employee shall be deemed to continue as an employee of the Company for all
purposes of this Plan, and any reference to employment by the Company shall also
be deemed to refer to employment by any parent or subsidiary of the Company.

                  5.6.4 OTHER SEVERANCE. In the event an employee of the Company
leaves the employ of the Company for any reason other than as set forth above in
this Section 5.6, any incentive stock option which such employee holds must be
exercised, to the extent it was exercisable at the date such employee left the
employ of the Company, not later than three (3) months after the date on which
the employee's employment terminates (or such shorter period as may be
prescribed in the option agreement, the minimum specified period being thirty
(30) days). The stock option shall terminate upon the expiration of such
prescribed period.

         5.7 EFFECT OF TERMINATION OF ENGAGEMENT OF NON-EMPLOYEES ON
NON-QUALIFIED STOCK OPTIONS. The Board, in its discretion, may provide in each
non-qualified stock option agreement issued to a consultant or non-employee
Director retained by the Company such provisions as the Board deems appropriate
with respect to whether, and if so when, the option (or any portion thereof)
shall be terminated prior to normal expiration (or otherwise affected) upon any
termination of the optionee's engagement as a consultant providing services to
the Company. Any reference in this Plan to services of a consultant to the
Company shall be deemed (for all purposes of this Plan) to mean and include the
existence of a consulting relationship with any parent corporation or subsidiary
corporation of the Company.

         5.8 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding the
provisions of Sections 5.6 and 5.7, if the exercise of an Option within the
applicable time periods set forth therein is prevented because the issuance of
shares upon such exercise would constitute a violation of any applicable federal
or state securities law or other law or regulation, the Option shall remain
exercisable until three (3) months after the date the optionee is notified by
the Company that the Option is exercisable, but in any event no later than the
expiration of ten (10) years from the date of grant pursuant to Section 4.3.

         5.9 ALL OPTIONS SUBJECT TO TERMS OF THIS PLAN. In addition to the
provisions contained in any option agreement granted under this Plan, each such
stock option agreement shall provide that the same is subject to the terms and
conditions of this Plan and each optionee shall be given a copy of this Plan.
Further, any terms or conditions contained in any such stock option agreement
granted hereunder which are inconsistent in any respect with the provisions of
this Plan shall be disregarded and void, or shall be deemed amended to the
extent necessary to comply with the provisions of this Plan and the intent of
the Board.

         5.10 OTHER PROVISIONS. Option agreements under the Plan shall contain
such other provisions, including, without limitation: (i) restrictions and
conditions upon the exercise of the option, (ii) rights of first refusal in
favor of the Company (or its assignees) applicable to shares of Common Stock
acquired upon exercise of an option which are subsequently proposed to be
transferred by the optionee, (iii) lock-up agreements (applicable in the event
of the public offering of the Common Stock of the Company) restricting an
optionee from any sales or other transfers of option stock for a designated
period of time following the effective date of a registration statement under
the Securities Act of 1933, (iv) other restrictions on the transferability or
right to retain shares of the Common Stock received upon the exercise of the
option, including repurchase rights at original cost based on a vesting
schedule, (v) commitments to pay cash bonuses, make loans or transfer other
property to an optionee upon exercise of any option, and (vi) restrictions
required by federal and applicable state securities laws, as the Board shall
deem necessary or advisable; provided that no such additional provision shall be
inconsistent with any other term or condition of this Plan and no such
additional provision shall cause any incentive stock option granted hereunder to
fail to qualify as an incentive stock option under Section 422 of the Internal
Revenue Code. Without limiting the generality of the foregoing, the Board may
provide in the form of stock option agreement that, in lieu of an exercise
schedule, the option may immediately be exercisable in full and provide a
"vesting schedule" with respect to the stock so purchased, giving the Company
(or its assignees) the right to repurchase the shares of Common Stock at cost
(or some other specified amount) to the extent such shares have not become
vested upon any termination of the optionee's employment or other engagement
with the Company, which vesting may depend upon or be related to the attainment
of performance goals or other conditions (such as the passage of stated time
periods) pursuant to which the obligation to resell such shares to the Company
shall lapse.


6. SECURITIES LAW REQUIREMENTS. The Board shall require any potential optionee,
as a condition of the exercise of an option, to represent and establish to the
satisfaction of the Board that all shares of Common Stock to be acquired upon
the exercise of such option will be acquired for investment and not for resale.
No shares of Common Stock shall be issued upon the exercise of any option unless
and until: (i) the Company and the optionee have satisfied all applicable
requirements under the Securities Act and the Securities Exchange Act of 1934,
as amended, (ii) any applicable listing requirement of any stock exchange on
which the Company's Common Stock is listed has been satisfied, and (iii) all
other applicable provisions of state and federal law have been satisfied. The


<PAGE>   9


Portola Packaging, Inc.
1994 Stock Option Plan
Page 9



Board shall cause such legends to be placed on certificates evidencing shares of
Common Stock issued upon exercise of an option as, in the opinion of the
Company's counsel, may be required by federal and applicable state securities
laws.


7. WITHHOLDING TAXES. The exercise of any option granted under this Plan shall
be conditioned upon the optionee's payment to the Company of all amounts (in
addition to the exercise price) required to meet federal, state or local taxes
of any kind required by law to be withheld with respect to shares to be issued
on exercise of such option. The Board, in its discretion, may declare cash
bonuses to an optionee to satisfy any such withholding requirements or may
incorporate provisions in the form of stock option agreement allowing (or after
grant of the option may permit, in its discretion) an optionee to satisfy any
such withholding obligations, in whole or in part, by delivery of shares of the
Company's Common Stock already owned by the optionee and which are not subject
to repurchase, forfeiture, vesting or other similar requirements or
restrictions. The fair market value of any such shares used to satisfy such
withholding obligations shall be determined as of the date the amount of tax to
be withheld is to be determined. The Company shall have the right to deduct from
payments of any kind otherwise due to the optionee (whether regular salary,
commissions, or otherwise) any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options granted under the Plan.


8. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

         8.1 STOCK SPLITS AND SIMILAR EVENTS. Subject to any required action by
the Company's Board and stockholders, the number of shares of Common Stock
covered by outstanding options granted under this Plan and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting from a
subdivision or combination of such shares or the payment of a stock dividend
(but only on the Common Stock) or any other increase or decrease in the number
of such outstanding shares of Common Stock effected without the receipt of
consideration by the Company; provided, however, that the conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."

         8.2 MERGERS AND ACQUISITIONS. Subject to any required action by the
Company's Board and stockholders, if the Company shall be the surviving
corporation in any merger or consolidation which results in the holders of the
outstanding voting securities of the Company (determined immediately prior to
such merger or consolidation) owning, directly or indirectly, at least a
majority of the beneficial interest in the outstanding voting securities of the
surviving corporation or its parent corporation (determined immediately after
such merger or consolidation), the options granted under this Plan shall pertain
and apply to the securities or other property to which a holder of the number of
shares subject to the unexercised portion of such options would have been
entitled. A dissolution


<PAGE>   10


Portola Packaging, Inc.
1994 Stock Option Plan
Page 10



or liquidation of the Company or a sale of all or substantially all its business
and assets or a merger or consolidation in which the Company is not the
surviving corporation or which results in the holders of the outstanding voting
securities of the Company (determined immediately prior to such merger or
consolidation) owning, directly or indirectly, less than a majority of the
beneficial interest in the outstanding voting securities of the surviving
corporation or its parent corporation (determined immediately after such merger
or consolidation) will cause the options granted hereunder to terminate, unless
the agreement of such sale, merger, consolidation or other acquisition otherwise
provides.

         8.3 BOARD'S DETERMINATION FINAL AND BINDING UPON OPTIONEES. The
foregoing determinations and adjustments in this Section 8 relating to stock or
securities of the Company shall be made by the Board, whose determination in
that respect shall be final, binding and conclusive. The Company shall give
notice of any such adjustment or action to each optionee; provided, however,
that any such adjustment or action shall be effective and binding for all
purposes, whether or not such notice is given or received.

         8.4 NO FRACTIONS OF SHARES. Fractions of shares shall not be issued by
the Company. Instead, such fractions of shares shall either be paid in cash at
fair market value or shall be rounded up or down to the nearest share, as
determined by the Board.


         8.5 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as hereinabove
expressly provided in this Section 8, no additional rights shall accrue to any
optionee by reason of any subdivision or combination of shares of the capital
stock of any class or the payment of any stock dividend or any other increase or
decrease in the number of shares of any class or by reason of any dissolution,
liquidation, merger or consolidation or spin-off of assets or of stock of
another corporation, and any issue by the Company of shares of stock of any
class or of securities convertible into shares of stock of any class shall not
affect, and no adjustment by reason thereof shall be made with respect to, the
number or exercise price of shares subject to options granted hereunder.

         8.6 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of options under
this Plan shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.


9. NO ADDITIONAL EMPLOYMENT RELATED RIGHTS OR BENEFITS

         9.1 NO SPECIAL EMPLOYMENT RIGHTS. Nothing contained in this Plan or in
any option granted hereunder shall confer upon any optionee any right with
respect to the continuation of his or her employment or other engagement by the
Company or interfere in any way with the right of the


<PAGE>   11


Portola Packaging, Inc.
1994 Stock Option Plan
Page 11



Company, subject to the terms of any separate employment or consulting agreement
to the contrary, at any time to terminate such employment or consulting
relationship or to increase or decrease the compensation of any optionee.
Whether an authorized leave of absence, or absence in military or government
service, shall constitute termination of an optionee's employment or other
engagement shall be determined by the Board.

         9.2 OTHER EMPLOYEE BENEFITS. The amount of any compensation deemed to
be received by any employee or consultant as a result of the exercise of an
option or the sale of shares received upon such exercise will not constitute
compensation with respect to which any other employment (or other engagement)
related benefits of such optionee are determined, including, without limitation,
benefits under any bonus, pension, profit-sharing, life insurance or salary
continuation plan, except as otherwise specifically determined by the Board or
as expressly provided for in the option agreement. The granting of an option
shall impose no obligation upon the optionee to exercise such option.


10. RIGHTS AS A STOCKHOLDER AND ACCESS TO INFORMATION. No optionee and no person
claiming under or through any such optionee shall be, or have any of the rights
or privileges of, a stockholder of the Company in respect of any of the shares
issuable upon the exercise of any option granted under this Plan, unless and
until the option is properly and lawfully exercised and a certificate
representing the shares so purchased is duly issued to the optionee or to his or
her estate. No adjustment shall be made for dividends or any other rights if the
record date relating to such dividend or other right is before the date the
optionee became a stockholder. Holders of options granted under this Plan shall
be provided annual financial statements. Upon written request to the Secretary
of the Company, any optionee shall be entitled to inspect, at the executive
offices of the Company, the information made available to stockholders of the
Company pursuant to Section 220 or any other applicable provision of the
Delaware General Corporation Law. The Company shall deliver to each optionee
during the period for which he or she has one or more options outstanding,
copies of all annual reports and other information which are provided to all
stockholders of the Company, except the Company shall not be required to deliver
such information to key employees whose duties in connection with the Company
assure their access to equivalent information.


11. MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS. Subject to the limitations
of this Plan, the Board may modify, extend or renew outstanding options granted
under the Plan. Furthermore, the Board may, subject to the other provisions of
this Plan, upon the cancellation of previously granted options having higher per
share exercise prices, regrant options at a lower price; provided, however, that
no such modification or cancellation and regrant of an option shall, without the
written consent of the optionee, alter or impair any rights of the optionee
under any option previously granted under the Plan.

12. USE OF PROCEEDS. The proceeds received from the sale of shares of the Common
Stock upon exercise of options granted under the Plan shall be used for general
corporate purposes.


13. RESERVATION OF SHARES. The Company, during the term of this Plan, will at
all times reserve and keep available such number of shares of its Common Stock
as shall be sufficient to satisfy the requirements of the Plan and all options
issued hereunder.


14. TERM OF PLAN.

         14.1 EFFECTIVE DATE. The Plan became effective when adopted by the
Board on November 18, 1994 but no stock option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's stockholders by the vote of the holders of a majority of the
outstanding shares of the Company present and entitled to vote at a duly held
meeting of the Company's stockholders (or by consent of the holders of the
outstanding shares of the Company entitled to vote) in accordance with the
requirements of the Company's Bylaws and the Delaware General Corporation Law.
If such stockholder approval is not obtained within twelve (12) months after the
date of the Board's adoption of the Plan, any incentive stock options previously
granted under the Plan shall terminate and no further incentive stock options
shall be granted. Subject to the foregoing limitation, options may be granted
under the Plan at any time after the effective date and before the date fixed
for termination of the Plan.

         14.2 TERMINATION. Unless sooner terminated in accordance with Section
15, the Plan shall terminate upon the earlier of: (i) the close of business on
the last business day preceding the tenth (10th) anniversary of the date of the
Plan's adoption by the Board occurs, or (ii) the date on which all shares
available for issuance under the Plan shall have been issued pursuant to options
granted under the Plan and none of such shares shall remain subject to
contractual repurchase rights of the Company pursuant to "vesting" or other
similar provisions. If the date of termination is determined under clause (i)
above, then any options outstanding on such date shall continue to have force
and effect in accordance with the provisions of the option agreements evidencing
such options.


15. EARLY TERMINATION AND AMENDMENT OF THE PLAN. The Board may from time to time
suspend or terminate the Plan or revise or amend it; provided, however, that,
without the approval of the Company's stockholders (except as to 15.1 below,
which also requires the consent of the affected optionees) at a duly held
meeting of the Company's stockholders by the vote of a majority of the shares
present and entitled to vote (or by written consent of the holders entitled to
vote) in compliance with the requirements of the Company's Bylaws and the
Delaware General Corporation Law, no such action of the Board shall:

         15.1 MODIFICATIONS OF OUTSTANDING OPTIONS. Without the consent of each
affected optionee, alter or impair any rights of an optionee under any option
previously granted under the Plan;

         15.2 INCREASES IN NUMBER OF SHARES SUBJECT TO THE PLAN. Increase the
aggregate number of shares of the Common Stock which may be issued upon exercise
of options granted under the Plan (except for adjustments made pursuant to
Section 8 hereof);

         15.3 CHANGES IN ELIGIBILITY. Change the designation of employees
eligible to receive incentive stock options under the Plan;

         15.4 PLAN DURATION. Extend the termination date beyond that provided in
Section 14.2;

         15.5 CHANGES NOT APPROVED BY LEGAL COUNSEL. Otherwise amend or modify
the Plan (or outstanding options) under circumstances where stockholder approval
is considered necessary in the opinion of legal counsel to the Company; or

         15.6 CHANGES TO THIS SECTION. Amend this Section 15 to defeat its
purposes.

                             PORTOLA PACKAGING, INC.
                    EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT
                                  OPTION TERMS

         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT ("OPTION AGREEMENT") by and between
Portola Packaging, Inc. , a Delaware corporation (the "COMPANY"), and the
employee (the "EMPLOYEE") named in the Employee Incentive Stock Option Agreement
and dated on the "DATE OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be incentive stock options within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to
purchase shares of the authorized but unissued Common Stock or treasury shares
of the Company ("COMMON STOCK"). The par value of the Company's Common Stock is
as set forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of an incentive stock option to the Employee, thereby allowing the
Employee to acquire an ownership interest (or increase his or her ownership
interest) in the Company.

                             O P T I O N   T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to the Employee a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Employee to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is intended to
qualify as an incentive stock option within the meaning of Section 422 of the
Internal Revenue Code but the Company does not represent or warrant that the
Option qualifies as such. Accordingly, the Employee understands that in order to
obtain the benefits of incentive stock option treatment under Section 421 of the
Internal Revenue Code, no sale or other disposition may be made of any shares
acquired upon exercise of the Option for at least one (1) year after the date of
the issuance of such shares upon exercise hereunder and for at least two (2)
years after the Date of Grant of the Option.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Employee must be
and remain in the employ of the Company, or of any Parent or Subsidiary
corporation of the Company (as defined in Internal Revenue Code Sections 424(e)
and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION," respectively),
during the entire period commencing with the Date of Grant of the Option and
ending with each of the periods appearing in the Option Agreement in order to
exercise the Option with respect to the shares applicable to any such period.
Except as otherwise expressly provided herein, the Employee's employment shall
be deemed to have terminated upon an actual termination of employment and when
such Parent or Subsidiary corporation of the Company ceases to have such
relationship with the Company. Any references herein to Employee's employment
with the Company shall be deemed to also refer to Employee's employment with any
such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Employee and successors-in-interest to
Employee shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Employee desires to sell
or otherwise transfer any of his or her purchased shares of Common Stock, the
Employee shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such proposed
transferee to Employee, and state the number of shares to be transferred, the
proposed consideration and all other material terms and conditions of the
proposed transfer.

                  4.2 OPTION OF COMPANY TO REPURCHASE.

                           4.2.1 REPURCHASE PRICE. For forty-five (45) days
following receipt of such notice, the Company (and its assignees as provided in
Section 4.3 below) shall have the option to elect to purchase some or all of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided that if the terms of payment set forth in the Employee's notice
were other than cash

against delivery, the Company (or its assignees) shall pay in cash or by check
for said shares equal to the fair market value thereof as determined in good
faith by the Board, except that to the extent such consideration is composed, in
whole or in part, of promissory notes, the Company (and its assignees) shall
have the option of similarly issuing promissory notes of like form, tenor and
effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Employee disagrees with the
determination of fair market value made by the Board, the Employee shall have
the right to have such fair market value determined by arbitration in accordance
with the rules of the American Arbitration Association. The arbitration shall be
held in the county in which the Company has its executive offices. The cost of
arbitration shall be borne in equal shares by the Company and the Employee.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it
shall give written notice to the Employee of its election and settlement for
such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including
its officers, directors or shareholders, with or without consideration.

                  4.4 CLOSING OF COMPANY REPURCHASE. In the event the Company
(or its assignees) elects to acquire some or all of the shares of the Employee
as specified in the Employee's notice, the Secretary of the Company shall so
notify the Employee within forty-five (45) days after receipt of the Employee's
notice, and settlement thereof shall be made in cash or by Company check not
later than forty-five (45) days after the date the Secretary of the Company
gives the Employee notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Employee's notice, the Employee may, within the sixty (60) day
period following the expiration of the forty-five (45) day period for electing
to exercise the purchase rights granted to the Company (and its assignees) in
Section 4.2, transfer the shares in the manner specified in his or her notice.
In that event, the transferee, assignee or other recipient shall, as a condition
of the transfer of ownership, receive and hold such shares subject to the
provisions of this Section 4 (and also subject to any other applicable
provisions hereof) and shall execute such documentation as may be requested by
the Company, including, but not limited to, the form of Notice of Exercise
attached hereto as Exhibit "A" (the "NOTICE OF EXERCISE").

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the terms and provisions of Sections 4, 5, 7, 10 and 13-22 hereof). In
this regard, the Employee's transfer of


<PAGE>   20

Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 4


any or all shares held subject to the Option (either during the Employee's
lifetime or on death by will or the laws of intestacy) to the Employee's
"Immediate Family," as herein defined, or to any custodian or trustee for the
account of the Employee or his or her Immediate Family shall be exempt from the
provisions of this Section 4. "IMMEDIATE FAMILY" as used herein shall mean the
spouse, lineal descendants, father, mother, brother, sister, niece or nephew of
the Employee.

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4
may be waived by the Company with respect to any transfer proposed by the
Employee only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or
purported sale or transfer, of the Common Stock subject to the Option shall be
null and void unless the terms, conditions and provisions of this Section 4 are
strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT. The foregoing right of
first refusal shall terminate upon the earlier of:

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public pursuant to a registration
statement filed with, and declared effective by, the United States Securities
and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Employee agrees not to sell, sell short, grant any option to
buy or otherwise dispose of the shares of Common Stock purchased pursuant to the
Option (except for any such shares which may be included in the registration)
for a period of up to one hundred eighty (180) days following the consummation
of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Employee shall be subject to this Section 5 provided and
only if the officers and directors of the Company are also subject to similar
arrangements.

         6. RIGHTS ON TERMINATION OF EMPLOYMENT. Upon the termination of the
Employee's employment with the Company (and with any Parent or Subsidiary
corporation of the Company), the Employee's right to exercise the Option shall
be limited in the manner set forth in this Section 6 (and the


<PAGE>   21

Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 5


Option shall terminate in the event not so exercised), and shall also be subject
to the limitation provided in Section 3.

                  6.1 DEATH. If the Employee's employment is terminated because
of the death of the Employee, the Employee's estate may, for a period of twelve
(12) months following the date of such termination, exercise the Option to the
extent it was exercisable by the Employee on the date of such termination. The
Employee's estate shall mean the Employee's legal representative upon death or
any person who acquires the right to exercise the Option by reason of such death
in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Employee's employment is terminated by
voluntary retirement at or after reaching sixty-five (65) years of age, the
Employee may, within three (3) months following such termination, exercise the
Option to the extent it was exercisable by the Employee on the date of such
termination unless the Employee dies prior to the expiration of such period, in
which event the Employee shall be treated as though the Employee had died on the
date of retirement and the provisions of Section 6.1 shall apply.

                  6.3 DISABILITY. If the Employee's employment is terminated
because of a disability, the Employee may, within twelve (12) months following
the date of such termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination unless the Employee
dies prior to the expiration of such period, in which event the Employee shall
be treated as though his or her death occurred on the date of termination due to
such disability and the provisions of Section 6.1 shall apply. The Employee
hereby acknowledges that the favorable tax treatment provided under Section 421
of the Internal Revenue Code may be inapplicable in the event the Option is not
exercised within three (3) months after the date of the Employee's termination
due to a partial, temporary or other disability not meeting the requirements of
Internal Revenue Code Section 22(e)(3).

                  6.4 TERMINATION FOR CAUSE. If the Employee's employment is
terminated for cause, the Option shall expire on Employee's termination date or
at such later time and on such conditions as determined by the Board. For
purposes of this paragraph, "cause" shall be defined as the willful breach or
habitual neglect of the duties which Employee is reasonably required to perform
by the Company, or any act of dishonesty, fraud, misrepresentation or other acts
of moral turpitude as would prevent the effective performance of Employee's
duties.

                  6.5 OTHER TERMINATION. If the Employee's employment is
terminated for any reason other than provided in Sections 6.1, 6.2, 6.3 and 6.4
above, the Employee or the Employee's estate may, within three (3) months after
the date of Employee's termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination.

                  6.6 TRANSFER OF EMPLOYMENT TO RELATED CORPORATION. In the
event the Employee severs his or her employment relationship with the Company to
become an employee of any Parent or Subsidiary corporation of the Company or if
the Employee leaves the employ of any Parent or


<PAGE>   22

Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 6


Subsidiary corporation to become an employee of the Company or of another such
Parent or Subsidiary corporation of the Company, the Employee shall be deemed to
continue his or her employment with the Company for all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Employee is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Employee should consult with the
Employee's own tax advisor as to the tax consequences to the Employee of any
such delayed exercise.

                  6.8 EXTENSION IF EMPLOYEE IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Employee to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Employee's service with the Company until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Employee
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Employee's employment, or (iii) the
Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting from a
subdivision or combination of such shares or the payment of a stock dividend
(but only on the Common Stock) or a recapitalization or any other increase or
decrease in the number of such outstanding shares of Common Stock effected
without the receipt of consideration by the Company; provided, however, that the
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." In the event that the
shares of Common Stock covered by the Option are reclassified by the Company,
other than pursuant to a transaction described in Section 7.2, then the Option
shall apply to the appropriate number of shares of newly classified Common Stock
designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. If the Company shall be a
constituent corporation in any merger or consolidation which results in the
holders of the outstanding voting securities of the Company (determined
immediately prior to such merger or consolidation) owning, directly or
indirectly, at least a majority of the beneficial interest in the outstanding
voting securities of the surviving corporation or its Parent corporation
(determined immediately after such merger or consolidation), the

Option shall pertain and apply to the securities or other property to which a
holder of the number of shares subject to the unexercised portion of the Option
would have been entitled. Any of (i) a dissolution or liquidation of the
Company; (ii) a sale of all or substantially all of the Company's business and
assets; or (iii) a merger or consolidation (in which the Company is a
constituent corporation) which results in the holders of the outstanding voting
securities of the Company (determined immediately prior to such merger or
consolidation) owning, directly or indirectly, less than a majority of the
beneficial interest in the outstanding voting securities of the surviving
corporation or its Parent corporation (determined immediately after such merger
or consolidation) will cause the Option to terminate, unless (A) the agreement
of such sale, exchange, merger, consolidation or other transaction otherwise
provides, or (B) a sale on the day preceding the scheduled consummation of such
event (the "TEST DATE") of shares acquired upon the exercise of the Option would
subject the Employee to liability under Section 16(b) of the Securities Exchange
Act of 1934, as amended, in which event the Option shall remain exercisable as
to the shares purchasable at the test date until the earliest to occur of (i)
the tenth (10th) day following the date on which a sale of such shares by the
Employee would no longer be subject to such liability, (ii) the one hundred
ninetieth (190th) day after the test date, or (iii) the Expiration Date.

                  7.3 BOARD'S DETERMINATION FINAL AND BINDING UPON THE EMPLOYEE.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Employee; provided,
however, that any such adjustment shall be effective and binding for all
purposes hereof whether or not such notice is given or received.

                  7.4 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Employee by reason of any subdivision or combination of shares of
the capital stock of any class or the payment of any stock dividend or any other
increase or decrease in the number of shares of any class or by reason of any
dissolution, liquidation, merger or consolidation or spin-off of assets or of
stock of another corporation, and any issue by the Company of shares of stock of
any class or of securities convertible into shares of stock of any class shall
not affect, and no adjustment by reason thereof shall be made with respect to,
the number or exercise price of shares subject to the Option. Neither the
Employee nor any person claiming under or through the Employee shall be, or have
any of the rights or privileges of, a shareholder of the Company in respect of
any of the shares issuable upon the exercise of the Option, unless and until the
Option is properly and lawfully exercised and a certificate representing the
shares so purchased is duly issued and delivered to the Employee or to his or
her estate.

                  7.5 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Employee by completing, executing and delivering to the Company
the Notice of Exercise specifying the number of shares of Common Stock which the
Employee elects to purchase. The Company's obligation to deliver shares upon the
exercise of the Option shall be subject to the Employee's satisfaction of all
applicable federal, state, local and foreign income and employment tax
withholding requirements, if any. Upon receipt of such Notice of Exercise and of
payment of the purchase price (and payment of applicable taxes as provided
above), the Company shall, as soon as reasonably possible and subject to all
other provisions hereof, deliver certificates for the shares of Common Stock so
purchased, registered in the Employee's name or in the name of his or her legal
representative (if applicable). Payment of the purchase price upon any exercise
of the Option shall be made by check acceptable to the Company or in cash;
provided, however, that the Board may, in its sole and absolute discretion,
accept any other legal consideration to the extent permitted under applicable
laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Employee's death, the Option shall be exercised only by the Employee's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under the Employee's will or, if the Employee
shall fail to make testamentary disposition of the Option, under the applicable
laws of descent and distribution. Any such transferee exercising the Option must
furnish the Company with (i) written Notice of Exercise and relevant information
as to his or her status, (ii) evidence satisfactory to the Company to establish
the validity of the transfer of the Option and compliance with any laws or
regulations pertaining to said transfer, and (iii) written acceptance of the
terms and conditions of the Option as contained herein.

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Employee, be exercisable only by the Employee and shall not be transferable or
assignable by the Employee in whole or in part other than by will or the laws of
descent and distribution. If the Employee shall make any such purported transfer
or assignment of the Option, such assignment shall be null and void and of no
force or effect whatsoever.

         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legend and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ___________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.


         11. NO RIGHT TO CONTINUED EMPLOYMENT. Nothing contained in the Option
shall: (i) confer upon the Employee any right with respect to the continuance of
his or her employment agreement with the Company, or with any Parent or
Subsidiary corporation of the Company, or (ii) limit in any way the right of the
Company, or of any Parent or Subsidiary corporation, to terminate the Employee's
employment at any time. Except to the extent the Company and Employee shall have
otherwise agreed in writing, Employee's employment shall be terminable by the
Company (or by a Parent or Subsidiary corporation, if applicable) at will.
Subject to Section 12, the Board in its sole discretion shall determine whether
any leave of absence or interruption in employment (including an interruption
during military service) shall be deemed a termination of employment for the
purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Employee's employment
shall not be deemed to terminate if the Employee takes any military leave, sick
leave, or other bona fide leave of absence approved by the Company, of ninety
(90) days or less. In the event of a leave in excess of ninety (90) days, the
Employee's employment shall be deemed to terminate on the ninety-first (91st)
day of the leave unless the Employee's right to reemployment remains guaranteed
by statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as employment for
purposes of Section 3 if and only if the leave of absence is designated by the
Company as (or required by law to be) a leave for which vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Employee acknowledges receipt of a
copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Employee represents that he or she is familiar with the terms and conditions of
the Plan, and hereby accepts the Option Agreement subject to all of the terms
and conditions thereof, which terms and conditions shall control to the extent
inconsistent in any respect with the provisions herein or in the Option
Agreement. The Employee hereby agrees to accept as binding, conclusive and final
all decisions and interpretations of the Board as to any questions arising under
the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option Agreement may be required or may desire to serve on
the other party to the Option Agreement in connection with the Option Agreement
shall be in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be
deemed complete on the date of actual delivery as shown by the addressee's
registry or certification receipt or at the expiration of the third (3rd)
business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Employee shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Employee shall deliver such Common Stock
endorsed in blank or accompanied by Stock Assignments Separate from Certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Employee of the Common Stock to the Company (and/or its
assignees) shall be made free of any and all claims, encumbrances, liens and
restrictions of every kind, other than those imposed hereunder.

         17. NOTICE OF SALES UPON DISQUALIFYING DISPOSITION. The Employee shall
dispose of the shares acquired pursuant to the Option Agreement only in
accordance with the provisions herein. In addition, the Employee shall promptly
notify the Chief Financial Officer of the Company if the Employee disposes of
any of the shares acquired pursuant to the Option Agreement within one (1) year
from the date the Employee exercises all or part of the Option or within two (2)
years of the Date of Grant of the Option. Until such time as the Employee
disposes of such shares in a manner consistent with the provisions herein, the
Employee shall hold all shares acquired pursuant to the Option Agreement in the
Employee's name (and not in the name of any nominee) for the one (1)-year period
immediately after exercise of the Option and the two (2)-year period immediately
after the Date of Grant of the Option. At any time during the one (1)-year or
two (2)-year periods set forth above, the Company may place a legend or legends
on any certificate or certificates representing shares acquired pursuant to the
Option requesting the transfer agent for the Company's stock to notify the
Company of any such transfers. The obligation of the Employee to notify the
Company of any such transfer shall continue notwithstanding that a legend has
been placed on the certificate or certificates pursuant to the preceding
sentence.

         18. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Employee and the Employee's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

Page 11



         19. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Employee unless such amendment is required to enable
the Option Agreement to qualify as an Incentive Stock Option.

         20. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Employee and
the Company with respect to the subject matter contained herein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Employee and the Company other than those set forth or provided for
herein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         21. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         22. INDEPENDENT TAX ADVICE. The Employee agrees that he or she has
obtained or will obtain the advice of independent tax counsel (or has determined
not to obtain such advice, having had adequate opportunity to do so) regarding
the federal and state income tax consequences of the receipt and exercise of the
Option and of the disposition of Common Stock acquired upon exercise of the
Option including advice regarding the imposition of the alternative minimum tax
which may result from items of tax preference, such as that generated in certain
cases by exercise of incentive stock options, and regarding holding period
requirements for preferential tax treatment. The Employee acknowledges that he
or she has not relied and will not rely upon any advice or representation by the
Company or by its employees or representatives with respect to the tax treatment
of the Option.

                         FORM OF NOTICE OF EXERCISE FOR
                    EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT


Portola Packaging, Inc.
890 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of ___________________, ________________, my
stock option (granted _________________) to purchase __________________________
shares (the "Option Shares") of the Common Stock of Portola Packaging, Inc., a
Delaware corporation (the "Company"). Payment of the option price of
$______________ is attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares


<PAGE>   30

Portola Packaging, Inc.
Page 2


and I live. In addition, I understand that if I am an affiliate of the Company,
I will not be permitted to resell solely under the Registration Statement any
Option Shares purchased under the Plan, and that such resales must be registered
in a separate registration statement or be effected in accordance with Rule 144
or another available exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.

                    EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT
                                  OPTION TERMS
               (WITH ACCELERATION OF VESTING ON CHANGE OF CONTROL)


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT ("OPTION AGREEMENT") by and between
Portola Packaging, Inc. , a Delaware corporation (the "COMPANY"), and the
employee (the "EMPLOYEE") named in the Employee Incentive Stock Option Agreement
and dated on the "DATE OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be incentive stock options within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to
purchase shares of the authorized but unissued Common Stock or treasury shares
of the Company ("COMMON STOCK"). The par value of the Company's Common Stock is
as set forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of an incentive stock option to the Employee, thereby allowing the
Employee to acquire an ownership interest (or increase his or her ownership
interest) in the Company.

                            O P T I O N    T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to the Employee a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Employee to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is intended to
qualify as an incentive stock option within the meaning of Section 422 of the
Internal Revenue Code but the Company does not represent or warrant that the
Option qualifies as such. Accordingly, the Employee understands that in order to
obtain the benefits of incentive stock option treatment under Section 421 of the
Internal Revenue Code, no sale or other disposition may be made of any shares
acquired upon exercise of the Option for at least one (1) year after the date of
the issuance of such shares upon exercise hereunder and for at least two (2)
years after the Date of Grant of the Option.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Employee must be
and remain in the employ of the Company, or of any Parent or Subsidiary
corporation of the Company (as defined in Internal Revenue Code Sections 424(e)
and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION," respectively),
during the entire period commencing with the Date of Grant of the Option and
ending with each of the periods appearing in the Option Agreement in order to
exercise the Option with respect to the shares applicable to any such period.
Except as otherwise expressly provided herein, the Employee's employment shall
be deemed to have terminated upon an actual termination of employment and when
such Parent or Subsidiary corporation of the Company ceases to have such
relationship with the Company. Any references herein to Employee's employment
with the Company shall be deemed to also refer to Employee's employment with any
such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Employee and successors-in-interest to
Employee shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Employee desires to sell
or otherwise transfer any of his or her purchased shares of Common Stock, the
Employee shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such proposed
transferee to Employee, and state the number of shares to be transferred, the
proposed consideration and all other material terms and conditions of the
proposed transfer.

                  4.2 OPTION OF COMPANY TO REPURCHASE.

                           4.2.1 REPURCHASE PRICE. For forty-five (45) days
following receipt of such notice, the Company (and its assignees as provided in
Section 4.3 below) shall have the option to elect to purchase some or all of the
shares specified in the notice at the price and upon the terms set forth in such


<PAGE>   36


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 3



notice; provided that if the terms of payment set forth in the Employee's notice
were other than cash against delivery, the Company (or its assignees) shall pay
in cash or by check for said shares equal to the fair market value thereof as
determined in good faith by the Board, except that to the extent such
consideration is composed, in whole or in part, of promissory notes, the Company
(and its assignees) shall have the option of similarly issuing promissory notes
of like form, tenor and effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Employee disagrees with the
determination of fair market value made by the Board, the Employee shall have
the right to have such fair market value determined by arbitration in accordance
with the rules of the American Arbitration Association. The arbitration shall be
held in the county in which the Company has its executive offices. The cost of
arbitration shall be borne in equal shares by the Company and the Employee.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it
shall give written notice to the Employee of its election and settlement for
such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including
its officers, directors or shareholders, with or without consideration.

                  4.4 CLOSING OF COMPANY REPURCHASE. In the event the Company
(or its assignees) elects to acquire some or all of the shares of the Employee
as specified in the Employee's notice, the Secretary of the Company shall so
notify the Employee within forty-five (45) days after receipt of the Employee's
notice, and settlement thereof shall be made in cash or by Company check not
later than forty-five (45) days after the date the Secretary of the Company
gives the Employee notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Employee's notice, the Employee may, within the sixty (60) day
period following the expiration of the forty-five (45) day period for electing
to exercise the purchase rights granted to the Company (and its assignees) in
Section 4.2, transfer the shares in the manner specified in his or her notice.
In that event, the transferee, assignee or other recipient shall, as a condition
of the transfer of ownership, receive and hold such shares subject to the
provisions of this Section 4 (and also subject to any other applicable
provisions hereof) and shall execute such documentation as may be requested by
the Company, including, but not limited to, the form of Notice of Exercise
attached hereto as Exhibit "A" (the "NOTICE OF EXERCISE").

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the


<PAGE>   37


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 4



terms and provisions of Sections 4, 5, 7, 10 and 13-22 hereof). In this regard,
the Employee's transfer of any or all shares held subject to the Option (either
during the Employee's lifetime or on death by will or the laws of intestacy) to
the Employee's "Immediate Family," as herein defined, or to any custodian or
trustee for the account of the Employee or his or her Immediate Family shall be
exempt from the provisions of this Section 4. "IMMEDIATE FAMILY" as used herein
shall mean the spouse, lineal descendants, father, mother, brother, sister,
niece or nephew of the Employee.

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4
may be waived by the Company with respect to any transfer proposed by the
Employee only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or
purported sale or transfer, of the Common Stock subject to the Option shall be
null and void unless the terms, conditions and provisions of this Section 4 are
strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT. The foregoing right of
first refusal shall terminate upon the earlier of:

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public pursuant to a registration
statement filed with, and declared effective by, the United States Securities
and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Employee agrees not to sell, sell short, grant any option to
buy or otherwise dispose of the shares of Common Stock purchased pursuant to the
Option (except for any such shares which may be included in the registration)
for a period of up to one hundred eighty (180) days following the consummation
of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Employee shall be subject to this Section 5 provided and
only if the officers and directors of the Company are also subject to similar
arrangements.

         6. RIGHTS ON TERMINATION OF EMPLOYMENT. Upon the termination of the
Employee's employment with the Company (and with any Parent or Subsidiary
corporation of the Company), the Employee's right to exercise the Option shall
be limited in the manner set forth in this Section 6 (and the


<PAGE>   38


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 5



Option shall terminate in the event not so exercised), and shall also be subject
to the limitation provided in Section 3.

                  6.1 DEATH. If the Employee's employment is terminated because
of the death of the Employee, the Employee's estate may, for a period of twelve
(12) months following the date of such termination, exercise the Option to the
extent it was exercisable by the Employee on the date of such termination. The
Employee's estate shall mean the Employee's legal representative upon death or
any person who acquires the right to exercise the Option by reason of such death
in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Employee's employment is terminated by
voluntary retirement at or after reaching sixty-five (65) years of age, the
Employee may, within three (3) months following such termination, exercise the
Option to the extent it was exercisable by the Employee on the date of such
termination unless the Employee dies prior to the expiration of such period, in
which event the Employee shall be treated as though the Employee had died on the
date of retirement and the provisions of Section 6.1 shall apply.

                  6.3 DISABILITY. If the Employee's employment is terminated
because of a disability, the Employee may, within twelve (12) months following
the date of such termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination unless the Employee
dies prior to the expiration of such period, in which event the Employee shall
be treated as though his or her death occurred on the date of termination due to
such disability and the provisions of Section 6.1 shall apply. The Employee
hereby acknowledges that the favorable tax treatment provided under Section 421
of the Internal Revenue Code may be inapplicable in the event the Option is not
exercised within three (3) months after the date of the Employee's termination
due to a partial, temporary or other disability not meeting the requirements of
Internal Revenue Code Section 22(e)(3).

                  6.4 TERMINATION FOR CAUSE. If the Employee's employment is
terminated for cause, the Option shall expire on Employee's termination date or
at such later time and on such conditions as determined by the Board. For
purposes of this paragraph, "cause" shall be defined as the willful breach or
habitual neglect of the duties which Employee is reasonably required to perform
by the Company, or any act of dishonesty, fraud, misrepresentation or other acts
of moral turpitude as would prevent the effective performance of Employee's
duties.

                  6.5 OTHER TERMINATION. If the Employee's employment is
terminated for any reason other than provided in Sections 6.1, 6.2, 6.3 and 6.4
above, the Employee or the Employee's estate may, within three (3) months after
the date of Employee's termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination.

                  6.6 TRANSFER OF EMPLOYMENT TO RELATED CORPORATION. In the
event the Employee severs his or her employment relationship with the Company to
become an employee of any Parent or Subsidiary corporation of the Company or if
the Employee leaves the employ of any Parent or


<PAGE>   39


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 6


Subsidiary corporation to become an employee of the Company or of another such
Parent or Subsidiary corporation of the Company, the Employee shall be deemed to
continue his or her employment with the Company for all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Employee is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Employee should consult with the
Employee's own tax advisor as to the tax consequences to the Employee of any
such delayed exercise.

                  6.8 EXTENSION IF EMPLOYEE IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Employee to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Employee's service with the Company until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Employee
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Employee's employment, or (iii) the
Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting from a
subdivision or combination of such shares or the payment of a stock dividend
(but only on the Common Stock) or a recapitalization or any other increase or
decrease in the number of such outstanding shares of Common Stock effected
without the receipt of consideration by the Company; provided, however, that the
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." In the event that the
shares of Common Stock covered by the Option are reclassified by the Company,
other than pursuant to a transaction described in Section 7.2, then the Option
shall apply to the appropriate number of shares of newly classified Common Stock
designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. Subject to any required action
by the Company's Board and stockholders, if the Company shall be a constituent
corporation in any merger or consolidation, provided the Option is not
terminated as set forth below in Section 7.3 upon consummation of such merger or
consolidation, this Option shall pertain and apply to the securities or



<PAGE>   40


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 7


other property to which a holder of the number of shares subject to the
unexercised portion of this Option would have been entitled upon such
consummation.

                  7.3 CHANGE OF CONTROL. In the event of a Change of Control (as
defined below), this Option shall become immediately exercisable in full as of
the date thirty (30) days prior to the consummation of such Change of Control.
The exercise or vesting that was permissible solely by reason of this Section
shall be conditioned upon the consummation of the Change of Control.
Furthermore, the Board, in its sole discretion, may arrange with the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "ACQUIRING CORPORATION"), for the Acquiring Corporation
to assume the Company's rights and obligations under outstanding Options (which,
for purposes of this Section 7.3, shall include Options that have become
immediately exercisable and fully vested as provided above) not exercised by the
Employee prior to the consummation of the Change of Control or substitute
options for the Acquiring Corporation's stock for such outstanding Options. Any
Options which are neither assumed nor substituted for by the Acquiring
Corporation in connection with the Change of Control nor exercised prior to the
consummation of the Change of Control shall terminate and cease to be
outstanding as of the effective date of the Change of Control. A "CHANGE OF
CONTROL" shall be deemed to have occurred in the event any of the following
occurs with respect to the Company:

                           7.3.1 the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange.

                           7.3.2 a merger or consolidation in which the Company
is not the surviving corporation, other than (i) a merger in which the
stockholders of the Company before such merger or consolidation retain directly
or indirectly, at least a majority of the voting stock of the surviving
corporation or the parent corporation of the surviving corporation and the
options are assumed or substituted by the surviving corporation which assumption
or substitution shall be binding on the Employee, or (ii) a merger or
consolidation with a wholly-owned subsidiary, a reincorporation of the Company
in a different jurisdiction, or other transaction in which there is no
substantial change in the stockholders of the Company and the Options are
assumed or substituted by the Acquiring Corporation, which assumption or
substitution shall be binding on the Employee.

                           7.3.3 a merger or consolidation in which the Company
is the surviving corporation where the stockholders of the Company before such
merger or consolidation do not retain, directly or indirectly, at least a
majority of the voting stock of the Company after such merger or consolidation.

                           7.3.4 the sale, exchange or transfer of all or
substantially all of the assets of the Company other than a sale, exchange or
transfer to one or more subsidiaries of the Company.

                           7.3.5 a liquidation or dissolution of the Company.

                           7.3.6 any other transaction which qualifies as a
"corporate transaction" under Section


<PAGE>   41


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 8


424 of the Internal Revenue Code wherein the stockholders of the Company give up
all of their equity interest in the Company (except for the acquisition, sale or
transfer of all or substantially all of the outstanding shares of the Company).

                  7.4 BOARD'S DETERMINATION FINAL AND BINDING UPON THE EMPLOYEE.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Employee; provided,
however, that any such adjustment shall be effective and binding for all
purposes hereof whether or not such notice is given or received.

                  7.5 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Employee by reason of any subdivision or combination of shares of
the capital stock of any class or the payment of any stock dividend or any other
increase or decrease in the number of shares of any class or by reason of any
dissolution, liquidation, merger or consolidation or spin-off of assets or of
stock of another corporation, and any issue by the Company of shares of stock of
any class or of securities convertible into shares of stock of any class shall
not affect, and no adjustment by reason thereof shall be made with respect to,
the number or exercise price of shares subject to the Option. Neither the
Employee nor any person claiming under or through the Employee shall be, or have
any of the rights or privileges of, a shareholder of the Company in respect of
any of the shares issuable upon the exercise of the Option, unless and until the
Option is properly and lawfully exercised and a certificate representing the
shares so purchased is duly issued and delivered to the Employee or to his or
her estate.

                  7.6 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Employee by completing, executing and delivering to the Company
the Notice of Exercise specifying the number of shares of Common Stock which the
Employee elects to purchase. The Company's obligation to deliver shares upon the
exercise of the Option shall be subject to the Employee's satisfaction of all
applicable federal, state, local and foreign income and employment tax
withholding requirements, if any. Upon receipt of such Notice of Exercise and of
payment of the purchase price (and payment of applicable taxes as provided
above), the Company shall, as soon as reasonably possible and subject to all
other provisions hereof, deliver certificates for the shares of Common Stock so
purchased, registered in the Employee's name or in the name of his or her legal
representative (if applicable). Payment of the purchase price upon any exercise
of the Option shall be made by check acceptable to the


<PAGE>   42


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 9


Company or in cash; provided, however, that the Board may, in its sole and
absolute discretion, accept any other legal consideration to the extent
permitted under applicable laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Employee's death, the Option shall be exercised only by the Employee's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under the Employee's will or, if the Employee
shall fail to make testamentary disposition of the Option, under the applicable
laws of descent and distribution. Any such transferee exercising the Option must
furnish the Company with (i) written Notice of Exercise and relevant information
as to his or her status, (ii) evidence satisfactory to the Company to establish
the validity of the transfer of the Option and compliance with any laws or
regulations pertaining to said transfer, and (iii) written acceptance of the
terms and conditions of the Option as contained herein.

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Employee, be exercisable only by the Employee and shall not be transferable or
assignable by the Employee in whole or in part other than by will or the laws of
descent and distribution. If the Employee shall make any such purported transfer
or assignment of the Option, such assignment shall be null and void and of no
force or effect whatsoever.

         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legend and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         11. NO RIGHT TO CONTINUED EMPLOYMENT. Nothing contained in the Option
shall: (i) confer upon the Employee any right with respect to the continuance of
his or her employment agreement with the Company, or with any Parent or
Subsidiary corporation of the Company, or (ii) limit in any way the


<PAGE>   43


Portola Packaging, Inc.
Option Terms
Employee Incentive Stock Option Agreement
Page 10


right of the Company, or of any Parent or Subsidiary corporation, to terminate
the Employee's employment at any time. Except to the extent the Company and
Employee shall have otherwise agreed in writing, Employee's employment shall be
terminable by the Company (or by a Parent or Subsidiary corporation, if
applicable) at will. Subject to Section 12, the Board in its sole discretion
shall determine whether any leave of absence or interruption in employment
(including an interruption during military service) shall be deemed a
termination of employment for the purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Employee's employment
shall not be deemed to terminate if the Employee takes any military leave, sick
leave, or other bona fide leave of absence approved by the Company, of ninety
(90) days or less. In the event of a leave in excess of ninety (90) days, the
Employee's employment shall be deemed to terminate on the ninety-first (91st)
day of the leave unless the Employee's right to reemployment remains guaranteed
by statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as employment for
purposes of Section 3 if and only if the leave of absence is designated by the
Company as (or required by law to be) a leave for which vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Employee acknowledges receipt of a
copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Employee represents that he or she is familiar with the terms and conditions of
the Plan, and hereby accepts the Option Agreement subject to all of the terms
and conditions thereof, which terms and conditions shall control to the extent

         16. FURTHER ASSURANCES. The Employee shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Employee shall deliver such Common Stock
endorsed in blank or accompanied by Stock Assignments Separate from Certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Employee of the Common Stock to the Company (and/or its
assignees) shall be made free of any and all claims, encumbrances, liens and
restrictions of every kind, other than those imposed hereunder.

         17. NOTICE OF SALES UPON DISQUALIFYING DISPOSITION. The Employee shall
dispose of the shares acquired pursuant to the Option Agreement only in
accordance with the provisions herein. In addition, the Employee shall promptly
notify the Chief Financial Officer of the Company if the Employee disposes of
any of the shares acquired pursuant to the Option Agreement within one (1) year
from the date the Employee exercises all or part of the Option or within two (2)
years of the Date of Grant of the Option. Until such time as the Employee
disposes of such shares in a manner consistent with the provisions herein, the
Employee shall hold all shares acquired pursuant to the Option Agreement in the
Employee's name (and not in the name of any nominee) for the one (1)-year period
immediately after exercise of the Option and the two (2)-year period immediately
after the Date of Grant of the Option. At any time during the one (1)-year or
two (2)-year periods set forth above, the Company may place a legend or legends
on any certificate or certificates representing shares acquired pursuant to the
Option requesting the transfer agent for the Company's stock to notify the
Company of any such transfers. The obligation of the Employee to notify the
Company of any such transfer shall continue notwithstanding that a legend has
been placed on the certificate or certificates pursuant to the preceding
sentence.

         18. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Employee and the Employee's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

         19. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Employee unless such amendment is required to enable
the Option Agreement to qualify as an Incentive Stock Option.

         20. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Employee and
the Company with respect to the subject matter contained herein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Employee and the Company other than those set forth or

provided for herein. To the extent contemplated herein, the provisions herein
shall survive any exercise of the Option and shall remain in full force and
effect.

         21. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         22. INDEPENDENT TAX ADVICE. The Employee agrees that he or she has
obtained or will obtain the advice of independent tax counsel (or has determined
not to obtain such advice, having had adequate opportunity to do so) regarding
the federal and state income tax consequences of the receipt and exercise of the
Option and of the disposition of Common Stock acquired upon exercise of the
Option including advice regarding the imposition of the alternative minimum tax
which may result from items of tax preference, such as that generated in certain
cases by exercise of incentive stock options, and regarding holding period
requirements for preferential tax treatment. The Employee acknowledges that he
or she has not relied and will not rely upon any advice or representation by the
Company or by its employees or representatives with respect to the tax treatment
of the Option.

                         FORM OF NOTICE OF EXERCISE FOR
                    EMPLOYEE INCENTIVE STOCK OPTION AGREEMENT


Portola Packaging, Inc.
890 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of ___________________, ________________, my
stock option (granted _________________) to purchase __________________________
shares (the "Option Shares") of the Common Stock of Portola Packaging, Inc., a
Delaware corporation (the "Company"). Payment of the option price of
$______________ is attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares


<PAGE>   48

Portola Packaging, Inc.

and I live. In addition, I understand that if I am an affiliate of the Company,
I will not be permitted to resell solely under the Registration Statement any
Option Shares purchased under the Plan, and that such resales must be registered
in a separate registration statement or be effected in accordance with Rule 144
or another available exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.

                             PORTOLA PACKAGING, INC.
                  EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT
                                  OPTION TERMS


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT ("OPTION AGREEMENT") by and
between Portola Packaging, Inc., a Delaware corporation (the "COMPANY"), and the
employee (the "EMPLOYEE") named in the Option Agreement and dated on the "DATE
OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be non-statutory stock options in that they do not qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to purchase
shares of the authorized but unissued Common Stock or treasury shares of the
Company ("COMMON STOCK"). The par value of the Company's Common Stock is as set
forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of a non-statutory stock option to the Employee, thereby allowing
the Employee to acquire an ownership interest (or increase his or her ownership
interest) in the Company.

                            O P T I O N    T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to the Employee a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Employee to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is a non-statutory
stock option in that it is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the Internal Revenue Code. Accordingly, the
Employee understands that under current law, he or she will recognize ordinary
income for federal income tax purposes upon exercise of the Option in an amount
equal to the excess (if any) of the fair market value of the shares of Common
Stock so purchased over


<PAGE>   53


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 2


the exercise price paid for such shares. Employee further understands that
Employee must satisfy all applicable federal, state, local and foreign income
and employment tax withholding requirements at the date of exercise.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Employee must be
and remain in the employ of the Company, or of any Parent or Subsidiary
corporation of the Company (as defined in Internal Revenue Code Sections 424(e)
and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION," respectively),
during the entire period commencing with the Date of Grant of the Option and
ending with each of the periods appearing in the Option Agreement in order to
exercise the Option with respect to the shares applicable to any such period.
Except as otherwise expressly provided herein, the Employee's employment shall
be deemed to have terminated upon an actual termination of employment and when
such Parent or Subsidiary corporation of the Company ceases to have such
relationship with the Company. Any references herein to Employee's employment
with the Company shall be deemed to also refer to Employee's employment with any
such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Employee and successors-in-interest to
Employee shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Employee desires to sell
or otherwise transfer any of his or her purchased shares of Common Stock, the
Employee shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such proposed
transferee to Employee, and state the number of shares to be transferred, the
proposed consideration and all other material terms and conditions of the
proposed transfer.

determined in good faith by the Board, except that to the extent such
consideration is composed, in whole or in part, of promissory notes, the Company
(and its assignees) shall have the option of similarly issuing promissory notes
of like form, tenor and effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Employee disagrees with the
determination of fair market value made by the Board, the Employee shall have
the right to have such fair market value determined by arbitration in accordance
with the rules of the American Arbitration Association. The arbitration shall be
held in the county in which the Company has its executive offices. The cost of
arbitration shall be borne in equal shares by the Company and the Employee.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it

such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including
its officers, directors or shareholders, with or without consideration.

                  4.4 CLOSING OF COMPANY REPURCHASE. In the event the Company

as specified in the Employee's notice, the Secretary of the Company shall so
notify the Employee within forty-five (45) days after receipt of the Employee's
notice, and settlement thereof shall be made in cash or by Company check not

gives the Employee notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Employee's notice, the Employee may, within the sixty (60) day
period following the expiration of the forty-five (45) day period for electing
to exercise the purchase rights granted to the Company (and its assignees) in
Section 4.2, transfer the shares in the manner specified in his or her notice.
In that event, the transferee, assignee or other recipient shall, as a condition

subject to the provisions of this Section 4 (and also subject to any other

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the terms and provisions of Sections 4, 5, 7, 10 and 13-21 hereof). In
this regard, the Employee's transfer of any or all shares held subject to the

intestacy) to the Employee's "Immediate Family," as herein defined, or to any
custodian or trustee for the account of the Employee or his or her Immediate
Family, shall be exempt from the provisions of this Section 4. "IMMEDIATE

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4

Employee only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or

strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT. The foregoing right of

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public pursuant to a registration
statement filed with, and declared effective by, the United States Securities
and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event

Option (except for any such shares which may be included in the registration)

of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Employee shall be subject to this Section 5 provided and

arrangements.

         6. RIGHTS ON TERMINATION OF EMPLOYMENT. Upon the termination of the
Employee's employment with the Company (and with any Parent or Subsidiary
corporation of the Company), the Employee's right to exercise the Option shall
be limited in the manner set forth in this Section 6 (and the Option shall
terminate in the event not so exercised), and shall also be subject to the
limitation provided in Section 3.

                  6.1 DEATH. If the Employee's employment is terminated because
of death of the Employee, the Employee's estate may, for a period of twelve (12)
months following the date of such termination exercise the Option to the extent
it was exercisable by the Employee on the date of such termination. The
Employee's estate shall mean the Employee's legal representative upon death or
any person who acquires the right to exercise the Option by reason of such death
in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Employee's employment is terminated by
voluntary retirement at or after reaching sixty-five (65) years of age, the
Employee may, within three (3) months following such termination, exercise the
Option to the extent it was exercisable by the Employee on the date of such
termination unless the Employee dies prior to the expiration of such period, in
which event the Employee shall be treated as though the Employee had died on the
date of retirement and the provisions of Section 6.1 shall apply.

                  6.3 DISABILITY. If the Employee's employment is terminated
because of a disability, the Employee may, within twelve (12) months following
the date of such termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination unless the Employee
dies prior to the expiration of such period, in which event the Employee shall
be treated as though his or her death occurred on the date of termination due to
such disability and the provisions of Section 6.1 shall apply.

                  6.4 TERMINATION FOR CAUSE. If the Employee's employment is
terminated for cause, the Option shall expire on Employee's termination date or
at such later time and on such conditions as determined by the Board. For
purposes of this paragraph, "cause" shall be defined as the willful breach or
habitual neglect of the duties which Employee is reasonably required to perform
by the Company, or any act of dishonesty, fraud, misrepresentation or other acts
of moral turpitude as would prevent the effective performance of Employee's
duties.

                  6.5 OTHER TERMINATION. If the Employee's employment is
terminated for any reason other than provided in Sections 6.1, 6.2, 6.3 and 6.4
above, the Employee or the Employee's estate may, within three (3) months after
the date of the Employee's termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination.

                  6.6 TRANSFER OF EMPLOYMENT TO RELATED CORPORATION. In the
event the Employee severs his or her employment relationship with the Company to
become an employee of any Parent or Subsidiary corporation of the Company or if
the Employee leaves the employ of any Parent or Subsidiary corporation to become
an employee of the Company or of another such Parent or Subsidiary corporation
of the Company, the Employee shall be deemed to continue his or her employment
with the Company for all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Employee is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Employee should consult with the
Employee's own tax advisor as to the tax consequences to the Employee of any
such delayed exercise.

                  6.8 EXTENSION IF EMPLOYEE IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Employee to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Employee's service with the Company until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Employee
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Employee's employment, or (iii) the
Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting from a
subdivision or combination of such shares or the payment of a stock dividend
(but only on the Common Stock) or a recapitalization or any other increase or
decrease in the number of such outstanding shares of Common Stock effected
without the receipt of consideration by the Company; provided, however, that the
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." In the event that the
shares of Common Stock covered by the Option are reclassified by the Company,
other than pursuant to a transaction described in Section 7.2, then the Option
shall apply to the appropriate number of shares of newly classified Common Stock
designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. If the Company shall be a
constituent corporation in any merger or consolidation which results in the
holders of the outstanding voting securities of the Company (determined
immediately prior to such merger or consolidation) owning, directly or
indirectly, at least a majority of the beneficial interest in the outstanding
voting securities of the surviving corporation or its Parent corporation
(determined immediately after such merger or consolidation), the Option shall
pertain and apply to the securities or other property to which a holder of the
number of shares subject to the unexercised portion of the Option would have
been entitled. Any of (i) a dissolution or liquidation of the Company; (ii) a
sale of all or substantially all of the Company's business and assets; or (iii)
a merger or consolidation (in which the Company is a constituent corporation)
which results in the holders of the outstanding voting securities of the Company
(determined immediately prior to such merger or consolidation) owning, directly
or indirectly, less than a majority of the beneficial interest in the
outstanding voting securities of the surviving corporation or its Parent
corporation (determined immediately after such merger or consolidation) will
cause the Option to terminate, unless (A) the agreement of such sale, exchange,
merger, consolidation or other transaction otherwise provides, or (B) a sale on
the day preceding the scheduled consummation of such event (the "TEST DATE") of
shares acquired upon the exercise of the Option would subject the Employee to
liability under Section 16(b) of the Securities Exchange Act of 1934, as
amended, in which event the Option shall remain exercisable as to the shares
purchasable at the test date until the earliest to occur of (i) the tenth (10th)
day following the date on which a sale of such shares by the Employee would no
longer be subject to such liability, (ii) the one hundred ninetieth (190th) day
after the test date, or (iii) the Expiration Date.

                  7.3 BOARD'S DETERMINATION FINAL AND BINDING UPON THE EMPLOYEE.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Employee; provided,


<PAGE>   59


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 8


however, that any such adjustment shall be effective and binding for all
purposes hereof whether or not such notice is given or received.

                  7.4 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Employee by reason of any subdivision or combination of shares of
the capital stock of any class or the payment of any stock dividend or any other
increase or decrease in the number of shares of any class or by reason of any
dissolution, liquidation, merger or consolidation or spin-off of assets or of
stock of another corporation, and any issue by the Company of shares of stock of
any class or of securities convertible into shares of stock of any class shall
not affect, and no adjustment by reason thereof shall be made with respect to,
the number or exercise price of shares subject to the Option. Neither the
Employee nor any person claiming under or through the Employee shall be, or have
any of the rights or privileges of, a shareholder of the Company in respect of
any of the shares issuable upon the exercise of the Option, unless and until the
Option is properly and lawfully exercised and a certificate representing the
shares so purchased is duly issued and delivered to the Employee or to his or
her estate.

                  7.5 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Employee by completing, executing and delivering to the Company
the Notice of Exercise specifying the number of shares of Common Stock which the
Employee elects to purchase. The Company's obligation to deliver shares upon the
exercise of the Option shall be subject to the Employee's satisfaction of all
applicable federal, state, local and foreign income and employment tax
withholding requirements, if any. Upon receipt of such Notice of Exercise and of
payment of the purchase price (and payment of applicable taxes as provided
above), the Company shall, as soon as reasonably possible and subject to all
other provisions hereof, deliver certificates for the shares of Common Stock so
purchased, registered in the Employee's name or in the name of his or her legal
representative (if applicable). Payment of the purchase price upon any exercise
of the Option shall be made by check acceptable to the Company or in cash;
provided, however, that the Board may, in its sole and absolute discretion,
accept any other legal consideration to the extent permitted under applicable
laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Employee's death, the Option shall be exercised only by the Employee's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under the Employee's will or, if the Employee
shall fail to make testamentary disposition of the Option, under the applicable
laws of descent


<PAGE>   60


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 9


and distribution. Any such transferee exercising the Option must furnish the
Company with (i) written Notice of Exercise and relevant information as to his
or her status, (ii) evidence satisfactory to the Company to establish the
validity of the transfer of the Option and compliance with any laws or
regulations pertaining to said transfer, and (iii) written acceptance of the
terms and conditions of the Option as contained herein.

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Employee, be exercisable only by the Employee and shall not be transferable or
assignable by the Employee in whole or in part other than by will or the laws of
descent and distribution. If the Employee shall make any such purported transfer
or assignment of the Option, such assignment shall be null and void and of no
force or effect whatsoever.

         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legends and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED [DATE OF
                  GRANT], A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         11. NO RIGHT TO CONTINUED EMPLOYMENT. Nothing contained in the Option
shall: (i) confer upon the Employee any right with respect to the continuance of
his or her employment agreement with the Company, or with any Parent or
Subsidiary corporation of the Company, or (ii) limit in any way the right of the
Company, or of any Parent or Subsidiary corporation, to terminate the Employee's
employment at any time. Except to the extent the Company and Employee shall have
otherwise agreed in writing, Employee's employment shall be terminable by the
Company (or by a Parent or Subsidiary corporation, if applicable) at will.
Subject to Section 12, the Board in its sole discretion shall determine


<PAGE>   61


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 10


whether any leave of absence or interruption in employment (including an
interruption during military service) shall be deemed a termination of
employment for the purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Employee's employment
shall not be deemed to terminate if the Employee takes any military leave, sick
leave, or other bona fide leave of absence approved by the Company, of ninety
(90) days or less. In the event of a leave in excess of ninety (90) days, the
Employee's employment shall be deemed to terminate on the ninety-first (91st)
day of the leave unless the Employee's right to reemployment remains guaranteed
by statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as employment for
purposes of Section 3 if and only if the leave of absence is designated by the
Company as (or required by law to be) a leave for which vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Employee acknowledges receipt of a
copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Employee represents that he or she is familiar with the terms and conditions of
the Plan, and hereby accepts the Option Agreement subject to all of the terms
and conditions thereof, which terms and conditions shall control to the extent
inconsistent in any respect with the provisions herein or in the Option
Agreement. The Employee hereby agrees to accept as binding, conclusive and final
all decisions and interpretations of the Board as to any questions arising under
the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option Agreement may be required or may desire to serve on
the other party to the Option Agreement in connection with the Option Agreement
shall be in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be
deemed complete on the date of actual delivery as shown by the addressee's
registry or certification receipt or at the expiration of the third (3rd)
business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Employee shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be


<PAGE>   62


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 11


reasonably necessary to effectuate the terms and intent of the Option and these
Option Terms and, when required by any provision herein to transfer all or any
portion of the Common Stock purchased hereunder to the Company (or its
assignees), the Employee shall deliver such Common Stock endorsed in blank or
accompanied by Stock Assignments Separate from Certificate duly endorsed in
blank, so that title thereto will pass by delivery alone. Any sale or transfer
by the Employee of the Common Stock to the Company (and/or its assignees) shall
be made free of any and all claims, encumbrances, liens and restrictions of
every kind, other than those imposed hereunder.

         17. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Employee and the Employee's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

         18. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Employee.

         19. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Employee and
the Company with respect to the subject matter contained therein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Employee and the Company other than those set forth or provided
therein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         20. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         21. INDEPENDENT TAX ADVICE. The Employee agrees that he or she has
obtained or will obtain the advice of independent tax counsel (or has determined
not to obtain such advice, having had adequate opportunity to do so) regarding
the federal and state income tax consequences of the receipt and exercise of the
Option and of the disposition of Common Stock acquired upon exercise of the
Option, including advice regarding the imposition of the alternative minimum tax
which may result from items of tax preference, and regarding holding period
requirements for preferential tax treatment. The Employee acknowledges that he
or she has not relied and will not rely upon any advice or representation by the
Company or by its employees or representatives with respect to the tax treatment
of the Option.

                  EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT


Portola Packaging, Inc.
898 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

                           I hereby exercise, as of ___________________,
________________, my stock option (granted _________________) to purchase
________________________ shares (the "Option Shares") of the Common Stock of
Portola Packaging, Inc., a Delaware corporation (the "Company"). Payment of the
option price of $______________ is attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares and I live. In addition, I understand that if I am an
affiliate of the Company,


<PAGE>   65


Portola Packaging, Inc.
Page 2



I will not be permitted to resell solely under the Registration Statement any
Option Shares purchased under the Plan, and that such resales must be registered
in a separate registration statement or be effected in accordance with Rule 144
or another available exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.

                             PORTOLA PACKAGING, INC.
                  EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT
                                  OPTION TERMS
               (WITH ACCELERATION OF VESTING ON CHANGE OF CONTROL)


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT ("OPTION AGREEMENT") by and
between Portola Packaging, Inc., a Delaware corporation (the "COMPANY"), and the
employee (the "EMPLOYEE") named in the Option Agreement and dated on the "DATE
OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be non-statutory stock options in that they do not qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to purchase
shares of the authorized but unissued Common Stock or treasury shares of the
Company ("COMMON STOCK"). The par value of the Company's Common Stock is as set
forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of a non-statutory stock option to the Employee, thereby allowing
the Employee to acquire an ownership interest (or increase his or her ownership
interest) in the Company.

                             O P T I O N  T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to the Employee a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Employee to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is a non-statutory
stock option in that it is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the Internal Revenue Code. Accordingly, the
Employee understands that under current law, he or she will recognize ordinary
income for federal income tax purposes upon exercise of the Option in an amount


<PAGE>   70

Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 2


equal to the excess (if any) of the fair market value of the shares of Common
Stock so purchased over the exercise price paid for such shares. Employee
further understands that Employee must satisfy all applicable federal, state,
local and foreign income and employment tax withholding requirements at the date
of exercise.

         3. EXERCISE.

                 3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Employee must be
and remain in the employ of the Company, or of any Parent or Subsidiary
corporation of the Company (as defined in Internal Revenue Code Sections 424(e)
and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION," respectively),
during the entire period commencing with the Date of Grant of the Option and
ending with each of the periods appearing in the Option Agreement in order to
exercise the Option with respect to the shares applicable to any such period.
Except as otherwise expressly provided herein, the Employee's employment shall
be deemed to have terminated upon an actual termination of employment and when
such Parent or Subsidiary corporation of the Company ceases to have such
relationship with the Company. Any references herein to Employee's employment
with the Company shall be deemed to also refer to Employee's employment with any
such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Employee and successors-in-interest to
Employee shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Employee desires to sell
or otherwise transfer any of his or her purchased shares of Common Stock, the
Employee shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such proposed
transferee to Employee, and state the number of shares to be transferred, the
proposed consideration and all other material terms and conditions of the
proposed transfer.

following receipt of such notice, the Company (and its assignees as provided in
Section 4.3 below) shall have the option to elect to purchase some or all of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided that if the terms of payment set forth in the Employee's notice
were other than cash against delivery, the Company (or its assignees) shall pay
in cash or by check for said shares equal to the fair market value thereof as
determined in good faith by the Board, except that to the extent such
consideration is composed, in whole or in part, of promissory notes, the Company
(and its assignees) shall have the option of similarly issuing promissory notes
of like form, tenor and effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Employee disagrees with the
determination of fair market value made by the Board, the Employee shall have
the right to have such fair market value determined by arbitration in accordance
with the rules of the American Arbitration Association. The arbitration shall be
held in the county in which the Company has its executive offices. The cost of
arbitration shall be borne in equal shares by the Company and the Employee.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it

such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including
its officers, directors or shareholders, with or without consideration.

later than forty-five (45) days after the date the Secretary of the Company
gives the Employee notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Employee's notice, the Employee may, within the sixty (60) day
period following the expiration of the forty-five (45) day period for electing
to exercise the purchase rights granted to the Company (and its assignees) in
Section 4.2, transfer the shares in the manner specified in his or her notice.
In that event, the transferee,


<PAGE>   72


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 4


assignee or other recipient shall, as a condition of the transfer of ownership,
receive and hold such shares subject to the provisions of this Section 4 (and
also subject to any other applicable provisions hereof) and shall execute such
documentation as may be requested by the Company, including, but not limited to,

EXERCISE").

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the terms and provisions of Sections 4, 5, 7, 10 and 13-21 hereof). In
this regard, the Employee's transfer of any or all shares held subject to the
Option (either during the Employee's lifetime or on death by will or the laws of
intestacy) to the Employee's "Immediate Family," as herein defined, or to any
custodian or trustee for the account of the Employee or his or her Immediate
Family, shall be exempt from the provisions of this Section 4. "IMMEDIATE
FAMILY" as used herein shall mean the spouse, lineal descendants, father,
mother, brother, sister, niece or nephew of the Employee.

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4
may be waived by the Company with respect to any transfer proposed by the
Employee only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or
purported sale or transfer, of the Common Stock subject to the Option shall be
null and void unless the terms, conditions and provisions of this Section 4 are
strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT.  The foregoing right
of first refusal shall terminate upon the earlier of:

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public pursuant to a registration
statement filed with, and declared effective by, the United States Securities
and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended
(the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Employee agrees not to sell, sell short,


<PAGE>   73

Portola Packaging, Inc.

Employee Non-Statutory Stock Option Agreement
Page 5


grant any option to buy or otherwise dispose of the shares of Common Stock
purchased pursuant to the Option (except for any such shares which may be
included in the registration) for a period of up to one hundred eighty (180)
days following the consummation of such offering. The Company may impose
stop-transfer instructions with respect to the shares of the Common Stock
subject to the foregoing restriction until the end of said period. The Employee
shall be subject to this Section 5 provided and only if the officers and
directors of the Company are also subject to similar arrangements.

         6. RIGHTS ON TERMINATION OF EMPLOYMENT. Upon the termination of the
Employee's employment with the Company (and with any Parent or Subsidiary
corporation of the Company), the Employee's right to exercise the Option shall
be limited in the manner set forth in this Section 6 (and the Option shall
terminate in the event not so exercised), and shall also be subject to the
limitation provided in Section 3.

                  6.1 DEATH. If the Employee's employment is terminated because
of death of the Employee, the Employee's estate may, for a period of twelve (12)
months following the date of such termination exercise the Option to the extent
it was exercisable by the Employee on the date of such termination. The
Employee's estate shall mean the Employee's legal representative upon death or
any person who acquires the right to exercise the Option by reason of such death
in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Employee's employment is terminated by
voluntary retirement at or after reaching sixty-five (65) years of age, the
Employee may, within three (3) months following such termination, exercise the
Option to the extent it was exercisable by the Employee on the date of such
termination unless the Employee dies prior to the expiration of such period, in
which event the Employee shall be treated as though the Employee had died on the
date of retirement and the provisions of Section 6.1 shall apply.

                  6.3 DISABILITY. If the Employee's employment is terminated
because of a disability, the Employee may, within twelve (12) months following
the date of such termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination unless the Employee
dies prior to the expiration of such period, in which event the Employee shall
be treated as though his or her death occurred on the date of termination due to
such disability and the provisions of Section 6.1 shall apply.

                  6.4 TERMINATION FOR CAUSE. If the Employee's employment is
terminated for cause, the Option shall expire on Employee's termination date or
at such later time and on such conditions as determined by the Board. For
purposes of this paragraph, "cause" shall be defined as the willful breach or
habitual neglect of the duties which Employee is reasonably required to perform
by the Company, or any act of dishonesty, fraud, misrepresentation or other acts
of moral turpitude as would prevent the effective performance of Employee's
duties.

Page 6


                  6.5 OTHER TERMINATION. If the Employee's employment is
terminated for any reason other than provided in Sections 6.1, 6.2, 6.3 and 6.4
above, the Employee or the Employee's estate may, within three (3) months after
the date of the Employee's termination, exercise the Option to the extent it was
exercisable by the Employee on the date of such termination.

                  6.6 TRANSFER OF EMPLOYMENT TO RELATED CORPORATION. In the
event the Employee severs his or her employment relationship with the Company to
become an employee of any Parent or Subsidiary corporation of the Company or if
the Employee leaves the employ of any Parent or Subsidiary corporation to become
an employee of the Company or of another such Parent or Subsidiary corporation
of the Company, the Employee shall be deemed to continue his or her employment
with the Company for all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Employee is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Employee should consult with the
Employee's own tax advisor as to the tax consequences to the Employee of any
such delayed exercise.

                  6.8 EXTENSION IF EMPLOYEE IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Employee to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Employee's service with the Company until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Employee
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Employee's employment, or (iii) the
Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting from a
subdivision or combination of such shares or the payment of a stock dividend
(but only on the Common Stock) or a recapitalization or any other increase or
decrease in the number of such outstanding shares of Common Stock effected
without the receipt of consideration by the Company; provided, however, that the
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." In the event that the
shares of Common Stock covered by the Option are reclassified by the Company,
other than pursuant to a transaction described in Section 7.2, then the Option
shall apply to the appropriate number of shares of newly classified Common Stock
designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. Subject to any required action
by the Company's Board and stockholders, if the Company shall be a constituent
corporation in any merger or consolidation, provided the option is not
terminates as set forth below in Section 7.3 upon consummation of such merger or
consolidation, this Option shall pertain and apply to the securities or other
property to which a holder of the number of shares subject to the unexercised
portion of this Option would have been entitled upon such consummation.

                  7.3 CHANGE OF CONTROL. In the event of a Change of Control (as
defined below), this Option shall become immediately exercisable in full as of
the date thirty (30) days prior to the consummation of such Change of Control.
The exercise or vesting that was permissible solely by reason of this Section
shall be conditioned upon the consummation of the Change of Control.
Furthermore, the Board, in its sole discretion, may arrange with the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "ACQUIRING CORPORATION"), for the Acquiring Corporation
to assume the Company's rights and obligations under outstanding Options (which,
for purposes of this Section 7.3, shall include Options that have become
immediately exercisable and fully vested as provided above) not exercised by the
Employee prior to the consummation of the Change of Control or substitute
options for the Acquiring Corporation's stock for such outstanding Options. Any
Options which are neither assumed nor substituted for by the Acquiring
Corporation in connection with the Change of Control nor exercised prior to the
consummation of the Change of Control shall terminate and cease to be
outstanding as of the effective date of the Change of Control. A "CHANGE OF
CONTROL" shall be deemed to have occurred in the event any of the following
occurs with respect to the Company:

Page 8


                           7.3.1 the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange.

                           7.3.2 a merger or consolidation in which the Company
is not the surviving corporation, other than (i) a merger in which the
stockholders of the Company before such merger or consolidation retain directly
or indirectly, at least a majority of the voting stock of the surviving
corporation or the parent corporation of the surviving corporation and the
options are assumed or substituted by the surviving corporation which assumption
or substitution shall be binding on the Employee, or (ii) a merger or
consolidation with a wholly-owned subsidiary, a reincorporation of the Company
in a different jurisdiction, or other transaction in which there is no
substantial change in the stockholders of the Company and the Options are
assumed or substituted by the Acquiring Corporation, which assumption or
substitution shall be binding on the Employee.

                           7.3.3 a merger or consolidation in which the Company
is the surviving corporation where the stockholders of the Company before such
merger or consolidation do not retain, directly or indirectly, at least a
majority of the voting stock of the Company after such merger or consolidation.

                           7.3.4 the sale, exchange or transfer of all or
substantially all of the assets of the Company, other than a sale, exchange or
transfer to one or more subsidiaries of the Company.

                           7.3.5 a liquidation or dissolution of the Company.

                           7.3.6 any other transaction which qualifies as a
"corporate transaction" under Section 424 of the Internal Revenue Code wherein
the stockholders of the Company give up all of their equity interest in the
Company (except for the acquisition, sale or transfer of all or substantially
all of the outstanding shares of the Company).

                  7.4 BOARD'S DETERMINATION FINAL AND BINDING UPON THE EMPLOYEE.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Employee; provided,
however, that any such adjustment shall be effective and binding for all
purposes hereof whether or not such notice is given or received.

                  7.5 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Employee by reason of any subdivision or combination of shares of
the capital stock of any class or the payment of any stock


<PAGE>   77


Portola Packaging, Inc.
Option Terms
Employee Non-Statutory Stock Option Agreement
Page 9


dividend or any other increase or decrease in the number of shares of any class
or by reason of any dissolution, liquidation, merger or consolidation or
spin-off of assets or of stock of another corporation, and any issue by the
Company of shares of stock of any class or of securities convertible into shares
of stock of any class shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or exercise price of shares subject to
the Option. Neither the Employee nor any person claiming under or through the
Employee shall be, or have any of the rights or privileges of, a shareholder of
the Company in respect of any of the shares issuable upon the exercise of the
Option, unless and until the Option is properly and lawfully exercised and a
certificate representing the shares so purchased is duly issued and delivered to
the Employee or to his or her estate.

                  7.6 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Employee by completing, executing and delivering to the Company
the Notice of Exercise specifying the number of shares of Common Stock which the
Employee elects to purchase. The Company's obligation to deliver shares upon the
exercise of the Option shall be subject to the Employee's satisfaction of all
applicable federal, state, local and foreign income and employment tax
withholding requirements, if any. Upon receipt of such Notice of Exercise and of
payment of the purchase price (and payment of applicable taxes as provided
above), the Company shall, as soon as reasonably possible and subject to all
other provisions hereof, deliver certificates for the shares of Common Stock so
purchased, registered in the Employee's name or in the name of his or her legal
representative (if applicable). Payment of the purchase price upon any exercise
of the Option shall be made by check acceptable to the Company or in cash;
provided, however, that the Board may, in its sole and absolute discretion,
accept any other legal consideration to the extent permitted under applicable
laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Employee's death, the Option shall be exercised only by the Employee's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under the Employee's will or, if the Employee
shall fail to make testamentary disposition of the Option, under the applicable
laws of descent and distribution. Any such transferee exercising the Option must
furnish the Company with (i) written Notice of Exercise and relevant information
as to his or her status, (ii) evidence satisfactory to the Company to establish
the validity of the transfer of the Option and compliance with any laws or
regulations pertaining to said transfer, and (iii) written acceptance of the
terms and conditions of the Option as contained herein.

Employee Non-Statutory Stock Option Agreement

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Employee, be exercisable only by the Employee and shall not be transferable or
assignable by the Employee in whole or in part other than by will or the laws of
descent and distribution. If the Employee shall make any such purported transfer
or assignment of the Option, such assignment shall be null and void and of no
force or effect whatsoever.

         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legends and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED [DATE
                  OF GRANT], A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         11. NO RIGHT TO CONTINUED EMPLOYMENT. Nothing contained in the Option
shall: (i) confer upon the Employee any right with respect to the continuance of
his or her employment agreement with the Company, or with any Parent or
Subsidiary corporation of the Company, or (ii) limit in any way the right of the
Company, or of any Parent or Subsidiary corporation, to terminate the Employee's
employment at any time. Except to the extent the Company and Employee shall have
otherwise agreed in writing, Employee's employment shall be terminable by the
Company (or by a Parent or Subsidiary corporation, if applicable) at will.
Subject to Section 12, the Board in its sole discretion shall determine whether
any leave of absence or interruption in employment (including an interruption
during military service) shall be deemed a termination of employment for the
purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Employee's employment
shall not be deemed to terminate if the Employee takes any military leave, sick
leave, or other bona fide leave of absence approved by the Company, of ninety
(90) days or less. In the event of a leave in excess of ninety (90) days, the
Employee's employment shall be deemed to terminate on the ninety-first (91st)
day

of the leave unless the Employee's right to reemployment remains guaranteed by
statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as employment for
purposes of Section 3 if and only if the leave of absence is designated by the
Company as (or required by law to be) a leave for which vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Employee acknowledges receipt of a
copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Employee represents that he or she is familiar with the terms and conditions of
the Plan, and hereby accepts the Option Agreement subject to all of the terms
and conditions thereof, which terms and conditions shall control to the extent
inconsistent in any respect with the provisions herein or in the Option
Agreement. The Employee hereby agrees to accept as binding, conclusive and final
all decisions and interpretations of the Board as to any questions arising under
the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option Agreement may be required or may desire to serve on
the other party to the Option Agreement in connection with the Option Agreement
shall be in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be
deemed complete on the date of actual delivery as shown by the addressee's
registry or certification receipt or at the expiration of the third (3rd)
business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Employee shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Employee shall deliver such Common Stock
endorsed in blank or accompanied by Stock Assignments Separate from Certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Employee of the Common Stock to the Company (and/or its
assignees) shall be made free of any and all claims, encumbrances, liens and
restrictions of every kind, other than those imposed hereunder.

         17. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Employee and the Employee's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

         18. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Employee.

         19. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Employee and
the Company with respect to the subject matter contained therein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Employee and the Company other than those set forth or provided
therein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         20. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         21. INDEPENDENT TAX ADVICE. The Employee agrees that he or she has
obtained or will obtain the advice of independent tax counsel (or has determined
not to obtain such advice, having had adequate opportunity to do so) regarding
the federal and state income tax consequences of the receipt and exercise of the
Option and of the disposition of Common Stock acquired upon exercise of the
Option, including advice regarding the imposition of the alternative minimum tax
which may result from items of tax preference, and regarding holding period
requirements for preferential tax treatment. The Employee acknowledges that he
or she has not relied and will not rely upon any advice or representation by the
Company or by its employees or representatives with respect to the tax treatment
of the Option.

                  EMPLOYEE NON-STATUTORY STOCK OPTION AGREEMENT


Portola Packaging, Inc.
898 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of ___________________, ________________, my
stock option (granted _________________) to purchase __________________ shares
(the "Option Shares") of the Common Stock of Portola Packaging, Inc., a Delaware
corporation (the "Company"). Payment of the option price of $______________ is
attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares and I live. In addition, I understand that if I am an
affiliate of the Company, I will not be permitted to


<PAGE>   83


Portola Packaging, Inc.
Page 2


resell solely under the Registration Statement any Option Shares purchased under
the Plan, and that such resales must be registered in a separate registration
statement or be effected in accordance with Rule 144 or another available
exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.

                             PORTOLA PACKAGING, INC.
                  DIRECTOR NON-STATUTORY STOCK OPTION AGREEMENT
                                  OPTION TERMS
               (WITH ACCELERATION OF VESTING ON CHANGE OF CONTROL)


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
DIRECTOR NON-STATUTORY STOCK OPTION AGREEMENT ("OPTION AGREEMENT") by and
between Portola Packaging, Inc., a Delaware corporation (the "COMPANY"), and the
Optionee (the "OPTIONEE") named in the Option Agreement and dated on the "DATE
OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be non-statutory stock options in that they do not qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to purchase
shares of the authorized but unissued Common Stock or treasury shares of the
Company ("COMMON STOCK"). The par value of the Company's Common Stock is as set
forth in the Option Agreement.

         B. _________________ is a Director of the Company (the "DIRECTOR").

         C. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of a non-statutory stock ----- option to the Optionee, thereby
allowing the Optionee to acquire an ownership interest (or increase his or her
ownership interest) in the Company.

                             O P T I O N  T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to the Optionee a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Optionee to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is a non-statutory
stock option in that it is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the


<PAGE>   88

Portola Packaging, Inc.
Option Terms
Director Non-Statutory Stock Option Agreement
Page 2


Internal Revenue Code. Accordingly, the Optionee understands that under current
law, he or she will recognize ordinary income for federal income tax purposes
upon exercise of the Option in an amount equal to the excess (if any) of the
fair market value of the shares of Common Stock so purchased over the exercise
price paid for such shares. Optionee further understands that Optionee must
satisfy all applicable federal, state, local and foreign income and employment
tax withholding requirements at the date of exercise.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, the Director must
be and remain a director or employee of the Company, or of any Parent or
Subsidiary corporation of the Company (as defined in Internal Revenue Code
Sections 424(e) and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION,"
respectively), during the entire period commencing with the Date of Grant of the
Option and ending with each of the periods appearing in the Option Agreement in
order for the Optionee to exercise the Option with respect to the shares
applicable to any such period. Any references herein to the Director serving as
a member of the Board or employee of the Company shall be deemed to also refer
to the Director serving as a member of the Board or an employee of any such
Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Optionee and successors-in-interest to
the Optionee shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Optionee desires to sell
or otherwise transfer any of his or her purchased shares of Common Stock, the
Optionee shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such proposed
transferee to the Optionee, and state the number of shares to be transferred,
the proposed consideration and all other material terms and conditions of the
proposed transfer.

held in the county in which the Company has its executive offices. The cost of

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Optionee agrees not to sell, sell short, grant any option to
buy or otherwise dispose of the shares of Common Stock purchased pursuant to the
Option (except for any such shares which may be included in the registration)
for a period of up to one hundred eighty (180) days following the consummation
of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Optionee shall be subject to this Section 5 provided and
only if the officers and directors of the Company are also subject to similar
arrangements.

         6. RIGHTS ON CESSATION OF SERVICE AS A DIRECTOR. Upon the termination
of the Director's service as a Director or an employee of the Company (and with
any Parent or Subsidiary corporation of the Company) (referred to as ceasing to
be an "ELIGIBLE DIRECTOR"), the Optionee's right to exercise the Option shall be
limited in the manner set forth in this Section 6 (and the Option shall
terminate in the event not so exercised), and shall also be subject to the
limitation provided in Section 3.

                  6.1 DEATH. Upon the death of the Director, the Optionee may,
or where the Optionee is the Director, the Director's estate may, for a period
of twelve (12) months following the date of such termination, exercise the
Option to the extent it was exercisable by the Optionee on the date of such
termination. The Director's estate shall mean the Director's legal
representative upon death or any person who acquires the right to exercise the
Option by reason of such death in accordance with Section 8.2.

                  6.2 DISABILITY. If the Director ceases to be an Eligible
Director, the Optionee may, within twelve (12) months following the date of such
termination, exercise the Option to the extent it was exercisable by the
Optionee on the date of such termination unless the Director dies prior to the
expiration of such period, in which event the Director shall be treated as
though his or her death occurred on the date of termination due to such
disability and the provisions of Section 6.1 shall apply.

                  6.3 OTHER TERMINATION. If the Director ceases to be an
Eligible Director for any reason other than provided in Sections 6.1 or 6.2
above, the Optionee may, or where the Optionee is the Director, the Director's
estate may, within three (3) months after the date of the Director's
termination, exercise the Option to the extent it was exercisable by the
Optionee on the date of such termination.

                  6.4 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Optionee is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Optionee should consult with the
Optionee's own tax advisor as to the tax consequences to the Optionee of any
such delayed exercise.

                  6.5 EXTENSION IF DIRECTOR IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Optionee to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of the
Director's service with the Company until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Optionee
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of the Director's service with the Company, or
(iii) the Expiration Date.

                  7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                           7.1 STOCK SPLITS AND SIMILAR EVENTS;
RECLASSIFICATIONS. The number of shares of Common Stock covered by the Option
and the exercise price thereof shall be proportionately adjusted for any
increase or decrease in the number of issued and outstanding shares of Common
Stock resulting from a subdivision or combination of such shares or the payment
of a stock dividend (but only on the Common Stock) or a recapitalization or any
other increase or decrease in the number of such outstanding shares of Common
Stock effected without the receipt of consideration by the Company; provided,
however, that the conversion of any convertible securities of the Company shall
not be deemed to have been "effected without receipt of consideration." In the
event that the shares of Common Stock covered by the Option are reclassified by
the Company, other than pursuant to a transaction described in Section 7.2, then
the Option shall apply to the appropriate number of shares of newly classified
Common Stock designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. Subject to any required action
by the Company's Board and stockholders, if the Company shall be a constituent
corporation in any merger or consolidation, provided the Option is not
terminated as set forth below in Section 7.3 upon consummation of such merger or
consolidation, this Option shall pertain and apply to the securities or other
property to which a holder of the number of shares subject to the unexercised
portion of this Option would have been entitled upon such consummation.

                  7.3 CHANGE OF CONTROL. In the event of a Change of Control
(as defined below), this Option shall become immediately exercisable in full as
of the date thirty (30) days prior to the consummation of such Change of
Control. The exercise or vesting that was permissible solely by reason of this
Section shall be conditioned upon the consummation of the Change of Control.
Furthermore, the Board, in its sole discretion, may arrange with the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "ACQUIRING CORPORATION"), for the Acquiring Corporation
to assume the Company's rights and obligations under outstanding Options (which,
for purposes of this Section 7.3, shall include Options that have become
immediately exercisable and fully vested as provided above) not exercised by the
Optionee prior to the consummation of the Change of Control or substitute
options for the Acquiring Corporation's stock for such outstanding Options. Any
Options which are neither assumed nor substituted for by the Acquiring
Corporation in connection with the Change of Control nor exercised prior to the
consummation of the Change of Control shall terminate and cease to be
outstanding as of the effective date of the Change of Control. A "CHANGE OF
CONTROL" shall be deemed to have occurred in the event any of the following
occurs with respect to the Company:

                           7.3.1 the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange.

                           7.3.2 a merger or consolidation in which the Company
is not the surviving corporation, other than (i) a merger in which the
stockholders of the Company before such merger or consolidation retain directly
or indirectly, at least a majority of the voting stock of the surviving
corporation or the parent corporation of the surviving corporation and the
options are assumed or substituted by the surviving corporation which assumption
or substitution shall be binding on the Optionee, or (ii) a merger or
consolidation with a wholly-owned subsidiary, a reincorporation of the Company
in a different jurisdiction, or other transaction in which there is no
substantial change in the stockholders of the Company and the Options are
assumed or substituted by the Acquiring Corporation, which assumption or
substitution shall be binding on the Optionee.

                           7.3.3 a merger or consolidation in which the Company
is the surviving corporation where the stockholders of the Company before such
merger or consolidation do not retain, directly or indirectly, at least a
majority of the voting stock of the Company after such merger or consolidation.

                           7.3.4 the sale, exchange or transfer of all or
substantially all of the assets of the Company, other than a sale, exchange or
transfer to one or more subsidiaries of the Company.

                           7.3.5 a liquidation or dissolution of the Company.

Page 8


                           7.3.6 any other transaction which qualifies as a
"corporate transaction" under Section 424 of the Internal Revenue Code wherein
the stockholders of the Company give up all of their equity interest in the
Company (except for the acquisition, sale or transfer of all or substantially
all of the outstanding shares of the Company).


                  7.4 BOARD'S DETERMINATION FINAL AND BINDING UPON THE OPTIONEE.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Optionee; provided,
however, that any such adjustment shall be effective and binding for all
purposes hereof whether or not such notice is given or received.

                  7.5 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Optionee by reason of any subdivision or combination of shares of
the capital stock of any class or the payment of any stock dividend or any other
increase or decrease in the number of shares of any class or by reason of any
dissolution, liquidation, merger or consolidation or spin-off of assets or of
stock of another corporation, and any issue by the Company of shares of stock of
any class or of securities convertible into shares of stock of any class shall
not affect, and no adjustment by reason thereof shall be made with respect to,
the number or exercise price of shares subject to the Option. Neither the
Optionee nor any person claiming under or through the Optionee shall be, or have
any of the rights or privileges of, a shareholder of the Company in respect of
any of the shares issuable upon the exercise of the Option, unless and until the
Option is properly and lawfully exercised and a certificate representing the
shares so purchased is duly issued and delivered to the Director or to his or
her estate.

                  7.6 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Optionee by completing, executing and delivering to the Company
the Notice of Exercise specifying the number of shares of Common Stock which the
Optionee elects to purchase. The Company's obligation to deliver shares upon the
exercise of the Option shall be subject to the Optionee's satisfaction of all
applicable federal, state, local and foreign income and employment tax
withholding requirements, if any. Upon receipt of such Notice of Exercise and of
payment of the purchase price (and payment of applicable taxes as provided
above), the Company shall, as soon as reasonably possible and subject to all

<PAGE>   95


Portola Packaging, Inc.
Option Terms
Director Non-Statutory Stock Option Agreement
Page 9

other provisions hereof, deliver certificates for the shares of Common Stock so
purchased, registered in the Optionee's name or in the name of his or her legal
representative (if applicable). Payment of the purchase price upon any exercise
of the Option shall be made by check acceptable to the Company or in cash;
provided, however, that the Board may, in its sole and absolute discretion,
accept any other legal consideration to the extent permitted under applicable
laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after the Director's death, where the Optionee is the Director, the Option shall
be exercised only by the Director's executor(s) or administrator(s) or the
person or persons duly authorized, or to whom the Option is transferred under
the Director's will or, if the Director shall fail to make testamentary
disposition of the Option, under the applicable laws of descent and
distribution. Any such transferee exercising the Option must furnish the Company
with (i) written Notice of Exercise and relevant information as to his or her
status, (ii) evidence satisfactory to the Company to establish the validity of
the transfer of the Option and compliance with any laws or regulations
pertaining to said transfer, and (iii) written acceptance of the terms and
conditions of the Option as contained herein.

         9. MEDIUM AND TIME OF PAYMENT.

                  9.1 The option price (and any and all federal, state and local
taxes payable by the Optionee by reason of the exercise of this Option as set
forth in Section 9.4) shall be payable upon the exercise of the Option in legal
tender of the United States (in cash or by certified check), shares of the
Common Stock, "Same Day Sales Proceeds" (as defined in Section 9.3) or any
combination of such legal tender, shares and Same Day Sales Proceeds.

                  9.2 For purposes of calculating payment of the Option price
and taxes, each share of the Common Stock surrendered in payment of such price
shall be valued at its fair market value on the date the Option is exercised.
Fair market value shall mean (i) the average of the closing bid and asked prices
of the Common Stock quoted in the Over-The-Counter Market or the closing price
quoted on any exchange on which the Common Stock is listed, whichever is
applicable, as published in the Western Edition of The Wall Street Journal for
the date the Option is exercised or, if no report is available for such date,
for the next preceding date for which such a report is available or (ii) if the
Common Stock is not traded Over-The-Counter or on an exchange or is not so
quoted by The Wall Street Journal, the amount determined in good faith by the
Chief Executive Officer of the Company on the date an option is exercised by
applying the rules and principles of valuation set forth in Treasury Regulation
Section 20.2031-2 relating to the valuation of stock for purposes of Section
2031 of the Internal Revenue Code. Notwithstanding the foregoing, this Option
may not be exercised by tender to the Company of shares of Common Stock to the
extent such tender of stock would constitute a violation of the provisions of
any law or regulation or agreement restricting the redemption of the Company's
Common Stock. Unless otherwise provided by the Board, this Option may not be
exercised by tender to the Company of shares of Common Stock unless such shares


<PAGE>   96


Portola Packaging, Inc.
Option Terms

Page 10


of Common Stock either have been owned by the Optionee for more than six (6)
months or were not acquired, directly or indirectly, from the Company.

                  9.3 "SAME DAY SALES PROCEEDS" shall mean the assignment of the
proceeds of a sale of some or all of the shares being acquired upon the exercise
of the Option (including, without limitation, through an exercise complying with
the provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to establish,
decline to approve or terminate any program or procedures for the exercise of
options by means of an assignment of the proceeds of a sale of some or all of
the shares of Common Stock to be acquired upon such exercise.

                  9.4 It is the intent of the parties that, at the election of
the Optionee, the Optionee may deliver shares of Common Stock as set forth in
and subject to the limitations imposed by Section 9.2 in payment of taxes
payable by the Optionee in connection with the exercise of this Option. Such
taxes shall include both state and federal income taxes on all ordinary income
realized by the Optionee as a result of the exercise of this Option. The shares
so delivered by the Optionee shall be valued at their fair market value in
accordance with Section 9.2 and the Company shall treat such shares as taxes
withheld. The Company shall pay over to the Internal Revenue Service in cash the
fair market value of shares so delivered and shall report to the Internal
Revenue Service and the Optionee on Form 1099-MISC or any other appropriate form
such withholding taxes.

         10. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Director, be exercisable only by the Optionee and shall not be transferable or
assignable by the Optionee in whole or in part other than by will or the laws of
descent and distribution. If the Optionee shall make any such purported transfer
or assignment of the Option, such assignment shall be null and void and of no
force or effect whatsoever.

         11. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legends and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

         12. NO RIGHT TO CONTINUE AS A DIRECTOR. Nothing contained in the Option
shall confer upon the Director any right to continue to serve as a director or
an employee of the Company, or with any Parent or Subsidiary corporation of the
Company. The Board in its sole discretion shall determine whether any leave of
absence or interruption in service (including an interruption during military
service) shall be deemed to result in the Director ceasing to be an Eligible
Director for the purposes hereof.

by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which

copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Optionee represents that he or she is familiar with the terms and conditions of
the Plan, and hereby accepts the Option Agreement subject to all of the terms
and conditions thereof, which terms and conditions shall control to the extent
inconsistent in any respect with the provisions herein or in the Option
Agreement. The Optionee hereby agrees to accept as binding, conclusive and final
all decisions and interpretations of the Board as to any questions arising under
the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option Agreement may be required or may desire to serve on
the other party to the Option Agreement in connection with the Option Agreement
shall be in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be

business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Optionee shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Optionee shall deliver such Common Stock
endorsed in blank or accompanied by stock assignments separate from certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Optionee of the Common Stock to the Company (and/or its
assignees) shall be made free of any and all claims, encumbrances, liens and
restrictions of every kind, other than those imposed hereunder.

         17. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the

successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

         18. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Optionee.

         19. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Optionee and
the Company with respect to the subject matter contained therein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Optionee and the Company other than those set forth or provided
therein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         20. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         21. INDEPENDENT TAX ADVICE. The Optionee agrees that he or she has
obtained or will obtain the advice of independent tax counsel (or has determined
not to obtain such advice, having had adequate opportunity to do so) regarding
the federal and state income tax consequences of the receipt and exercise of the
Option and of the disposition of Common Stock acquired upon exercise of the
Option, including advice regarding the imposition of the alternative minimum tax
which may result from items of tax preference, such as that generated in certain
cases by exercise of incentive stock options, and regarding holding period
requirements for preferential tax treatment. The Optionee acknowledges

                  DIRECTOR NON-STATUTORY STOCK OPTION AGREEMENT


Portola Packaging, Inc.
898 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of _____________, __________, my stock option
(granted _______________) to purchase __________ shares (the "Option Shares")
of the Common Stock of Portola Packaging, Inc., a Delaware corporation (the
"Company"). Payment of the option price of $______________ is attached to this
notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares and I live. In addition, I understand that if I am an
affiliate of the Company, I will not be permitted to
<PAGE>   102

Portola Packaging, Inc.
Page 2


resell solely under the Registration Statement any Option Shares purchased under
the Plan, and that such resales must be registered in a separate registration
statement or be effected in accordance with Rule 144 or another available
exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.



                                       Signed: _________________________________

                                       Print Name: _____________________________

                             PORTOLA PACKAGING, INC.
                 CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT
                                  OPTION TERMS


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT ("OPTION AGREEMENT"), by and
between Portola Packaging, Inc., a Delaware corporation (the "COMPANY"), and the
Consultant (the "CONSULTANT") named in the Option Agreement and dated on the
"DATE OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be non-statutory stock options in that they do not qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to purchase
shares of the authorized but unissued Common Stock or treasury shares of the
Company ("COMMON STOCK"). The par value of the Company's Common Stock is as set
forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of a non-statutory stock option to Consultant, thereby allowing
Consultant to acquire an ownership interest (or increase Consultant's ownership
interest) in the Company.

                              O P T I O N  T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to Consultant a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Consultant to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is a non-statutory
stock option in that it is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the Internal Revenue Code. Accordingly, the
Consultant understands that under current law, the Consultant will recognize
ordinary income for federal income tax purposes upon exercise of the Option in
an amount equal to the excess (if any) of the fair market value of the shares of
Common Stock so purchased over the exercise price paid for such shares.
Consultant further understands that Consultant must satisfy


<PAGE>   107


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 2


all applicable federal, state, local and foreign income and employment tax
withholding requirements at the date of exercise. Any reference herein to
"VESTED SHARES" shall mean those shares under the Option which have vested in
accordance with the Vesting Schedule set forth in the Option Agreement.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Consultant must be
and remain in a service relationship with the Company, or with any parent or
subsidiary corporation of the Company (as defined in Internal Revenue Code
Sections 424(e) and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION,"
respectively), during the entire period commencing with the Date of Grant of the
Option and ending with each of the periods appearing in the Option Agreement in
order to exercise the Option with respect to the shares applicable to any such
period. For purposes hereof "SERVICE RELATIONSHIP" shall mean being a duly
elected, acting corporate director, or an advisory board member, independent
contractor or employee. Except as otherwise expressly provided herein, the
Consultant's service relationship shall be deemed to have terminated upon an
actual termination of such service relationship and when any Parent or
Subsidiary corporation of the Company ceases to have such relationship with the
Company. Any references herein to Consultant's service relationship with the
Company shall be deemed to also refer to Consultant's service relationship with
any such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Consultant and successors-in-interest to
Consultant shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Consultant desires to sell
or otherwise transfer any of Consultant's purchased shares of Common Stock, the
Consultant shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such


<PAGE>   108

Page 3


proposed transferee to the Consultant and state the number of shares to be
transferred, the proposed consideration and all other material terms and
conditions of the proposed transfer.

                  4.2 OPTION OF COMPANY TO REPURCHASE.

                           4.2.1 REPURCHASE PRICE. For forty-five (45) days
following receipt of such notice, the Company (and its assignees as provided in
Section 4.3 below) shall have the option to elect to purchase some or all of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided that if the terms of payment set forth in the Consultant's
notice were other than cash against delivery, the Company (or its assignees)
shall pay in cash or by check for said shares equal to the fair market value
thereof as determined in good faith by the Board, except that to the extent such
consideration is composed, in whole or in part, of promissory notes, the Company
(and its assignees) shall have the option of similarly issuing promissory notes
of like form, tenor and effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Consultant disagrees with
the determination of fair market value made by the Board, the Consultant shall
have the right to have such fair market value determined by arbitration in
accordance with the rules of the American Arbitration Association. The
arbitration shall be held in the county in which the Company has its executive
offices. The cost of arbitration shall be borne in equal shares by the Company
and the Consultant.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it
shall give written notice to the Consultant of its election and settlement for
such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including
its officers, directors or shareholders, with or without consideration.

                  4.4 CLOSING OF COMPANY REPURCHASE. In the event the Company
(or its assignees) elects to acquire some or all of the shares of the Consultant
as specified in the Consultant's notice, the Secretary of the Company shall so
notify the Consultant within forty-five (45) days after receipt of the
Consultant's notice, and settlement thereof shall be made by cash or Company
check not later than forty-five (45) days after the date the Secretary of the
Company gives the Consultant notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Consultant's notice, the Consultant may, within the sixty (60)
day period following the expiration of the forty-five (45) day

Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 4


period for electing to exercise the purchase rights granted to the Company (and
its assignees) in Section 4.2, transfer the shares in the manner specified in
Consultant's notice. In that event, the transferee, assignee or other recipient
shall, as a condition of the transfer of ownership, receive and hold such shares
subject to the provisions of this Section 4 (and also subject to any other
applicable provisions hereof) and shall execute such documentation as may be
requested by the Company, including, but not limited to, the form of Notice of
Exercise attached hereto as Exhibit "A" (the "NOTICE OF EXERCISE").

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the terms and provisions of Sections 4, 5, 7, 10 and 13-21 hereof). In
this regard, the Consultant's transfer of any or all shares held subject to the
Option (either during the Consultant's lifetime or on death by will or the laws
of intestacy) to the Consultant's "Immediate Family," as herein defined, or to
any custodian or trustee for the account of the Consultant or Consultant's
Immediate Family, shall be exempt from the provisions of this Section 4.
"IMMEDIATE FAMILY" as used herein shall mean the spouse, lineal descendants,
father, mother, brother, sister, niece or nephew of the Consultant.

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4
may be waived by the Company with respect to any transfer proposed by the
Consultant only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or
purported sale or transfer, of the Common Stock subject to the Option shall be
null and void unless the terms, conditions and provisions of this Section 4 are
strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT. The foregoing right of
first refusal shall terminate upon the earlier of:

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public generally pursuant to a
registration statement filed with, and declared effective by, the United States
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

Page 5


         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Consultant agrees not to sell, sell short, grant any option to
buy or otherwise dispose of the shares of Common Stock purchased pursuant to the
Option (except for any such shares which may be included in the registration)
for a period of up to one hundred eighty (180) days following the consummation
of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Consultant shall be subject to this Section 5 provided
and only if the officers and directors of the Company are also subject to
similar arrangements.

         6. RIGHTS ON TERMINATION OF SERVICE RELATIONSHIP. Upon the termination
of Consultant's service relationship with the Company (and with any Parent or
Subsidiary corporation of the Company), the Consultant's right to exercise the
Option shall be limited in the manner set forth in this Section 6 (and the
Option shall terminate in the event not so exercised), and shall also be subject
to the limitation provided in Section 3.

                  6.1 DEATH. If the Consultant's service relationship is
terminated because of the death of the Consultant, the Consultant's estate may,
for a period of twelve (12) months following the date of such termination,
exercise the Option to the extent it was exercisable by the Consultant on the
date of such termination. The Consultant's estate shall mean the Consultant's
legal representative upon death or any person who acquires the right to exercise
the Option by reason of such death in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Consultant's service relationship is
terminated by voluntary retirement at or after reaching sixty-five (65) years of
age, the Consultant may, within three (3) months following such termination,
exercise the Option to the extent it was exercisable by the Consultant on the
date of such termination unless the Consultant dies prior to the expiration of
such period, in which event the Consultant shall be treated as though the
Consultant had died on the date of retirement and the provisions of Section 6.1
shall apply.

                  6.3 DISABILITY. If the Consultant's service relationship is
terminated because of a disability, the Consultant may, within twelve (12)
months following the date of such termination, exercise the Option to the extent
it was exercisable by the Consultant on the date of such termination unless the
Consultant dies prior to the expiration of such period, in which event the
Consultant shall be treated as though Consultant's death occurred on the date of
termination due to such disability and the provisions of Section 6.1 shall
apply.

                  6.4 TERMINATION FOR CAUSE. If the Consultant's service
relationship is terminated for cause, the Option shall expire on Consultant's
termination date or at such later time and on such conditions as determined by
the Board. For purposes of this paragraph, "cause" shall be defined as the

<PAGE>   111


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 6

willful breach or habitual neglect of the duties which Consultant is required to
perform by the Company, or any act of dishonesty, fraud, misrepresentation or
other acts of moral turpitude as would prevent the effective performance of
Consultant's duties.

                  6.5 OTHER TERMINATION. If the Consultant's service
relationship is terminated for any reason other than provided in Sections 6.1,
6.2, 6.3 and 6.4 above, the Consultant or the Consultant's estate may, within
three (3) months after the date of Consultant's termination, exercise the Option
to the extent it was exercisable by the Consultant on the date of such
termination.

                  6.6 TRANSFER OF SERVICE RELATIONSHIP TO RELATED CORPORATION.
In the event the Consultant leaves a service relationship with the Company to
enter a service relationship with any Parent or Subsidiary corporation of the
Company or if the Consultant leaves a service relationship with any Parent or
Subsidiary corporation to enter a consulting relationship with the Company or of
another such Parent or Subsidiary corporation of the Company, the Consultant
shall be deemed to continue in such service relationship with the Company for
all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Consultant is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Consultant should consult with
the Consultant's own tax advisor as to the tax consequences to the Consultant of
any such delayed exercise.

                  6.8 EXTENSION IF CONSULTANT IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Consultant to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Consultant's service relationship until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Consultant
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Consultant's service relationship, or (iii)
the Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting


<PAGE>   112


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 7


from a subdivision or combination of such shares or the payment of a stock
dividend (but only on the Common Stock) or a recapitalization or any other
increase or decrease in the number of such outstanding shares of Common Stock
effected without the receipt of consideration by the Company; provided, however,
that the conversion of any convertible securities of the Company shall not be
deemed to have been "effected without receipt of consideration." In the event
that the shares of Common Stock covered by the Option are reclassified by the
Company, other than pursuant to a transaction described in Section 7.2, then the
Option shall apply to the appropriate number of shares of newly classified
Common Stock designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. If the Company shall be a
constituent corporation in any merger or consolidation which results in the
holders of the outstanding voting securities of the Company (determined
immediately prior to such merger or consolidation) owning, directly or
indirectly, at least a majority of the beneficial interest in the outstanding
voting securities of the surviving corporation or its Parent corporation
(determined immediately after such merger or consolidation), the Option shall
pertain and apply to the securities or other property to which a holder of the
number of shares subject to the unexercised portion of the Option would have
been entitled. Any of (i) a dissolution or liquidation of the Company; (ii) a
sale of all or substantially all of the Company's business and assets; or (iii)
a merger or consolidation (in which the Company is a constituent corporation)
which results in the holders of the outstanding voting securities of the Company
(determined immediately prior to such merger or consolidation) owning, directly
or indirectly, less than a majority of the beneficial interest in the
outstanding voting securities of the surviving corporation or its Parent
corporation (determined immediately after such merger or consolidation) will
cause the Option to terminate, unless (A) the agreement of such sale, exchange,
merger, consolidation or other transaction otherwise provides, or (B) a sale on
the day preceding the scheduled consummation of such event (the "TEST DATE") of
shares acquired upon the exercise of the Option would subject the Consultant to
liability under Section 16(b) of the Securities Exchange Act of 1934, as
amended, in which event the Option shall remain exercisable as to the shares
purchasable at the test date until the earliest to occur of (i) the tenth (10th)
day following the date on which a sale of such shares by the Consultant would no
longer be subject to such liability, (ii) the one hundred ninetieth (190th) day
after the test date, or (iii) the Expiration Date.

                  7.3 BOARD'S DETERMINATION FINAL AND BINDING UPON CONSULTANT.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Consultant;
provided, however, that any such adjustment shall be effective and binding for
all purposes hereof whether or not such notice is given or received.

                  7.4 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Consultant by reason of any subdivision or combination of shares
of the capital stock of any class or the payment of any stock


<PAGE>   113


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 8


dividend or any other increase or decrease in the number of shares of any class
or by reason of any dissolution, liquidation, merger or consolidation or
spin-off of assets or of stock of another corporation, and any issue by the
Company of shares of stock of any class or of securities convertible into shares
of stock of any class shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or exercise price of shares subject to
the Option. Neither the Consultant nor any person claiming under or through the
Consultant shall be, or have any of the rights or privileges of, a shareholder
of the Company in respect of any of the shares issuable upon the exercise of the
Option, unless and until the Option is properly and lawfully exercised and a
certificate representing the shares so purchased is duly issued and delivered to
the Consultant or to Consultant's estate.

                  7.5 NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Consultant by completing, executing and delivering to the
Company the Notice of Exercise specifying the number of shares of Common Stock
which the Consultant elects to purchase. The Company's obligation to deliver
shares upon the exercise of the Option shall be subject to the Consultant's
satisfaction of all applicable federal, state, local and foreign income and
employment tax withholding requirements, if any. Upon receipt of such Notice of
Exercise and of payment of the purchase price (and payment of applicable taxes
as provided above), the Company shall, as soon as reasonably possible and
subject to all other provisions hereof, deliver certificates for the shares of
Common Stock so purchased, registered in the Consultant's name or in the name of
Consultant's legal representative (if applicable). Payment of the purchase price
upon any exercise of the Option shall be made by check acceptable to the Company
or in cash; provided, however, that the Board may, in its sole and absolute
discretion, accept any other legal consideration to the extent permitted under
applicable laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Consultant's death, the Option shall be exercised only by Consultant's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under Consultant's will or, if Consultant shall
fail to make testamentary disposition of the Option, under the applicable laws
of descent and distribution. Any such transferee exercising the Option must
furnish the Company with (i) written Notice of Exercise and relevant information
as to Consultant's status, (ii) evidence satisfactory to the Company to
establish the validity of the transfer of the Option and compliance with any
laws or regulations pertaining to said transfer, and (iii) written acceptance of
the terms and conditions of the Option as contained herein.

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Consultant, be exercisable only by the Consultant and shall not be transferable
or assignable by the Consultant in whole or in part other than by will or the
laws of descent and distribution. If the Consultant shall make any such
purported transfer or assignment of the Option, such assignment shall be null
and void and of no force or effect whatsoever.

         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legends and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
         RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A STOCK
         OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS INCORPORATED INTO SUCH
         STOCK OPTION AGREEMENT, DATED _________________, A COPY OF WHICH IS ON
         FILE WITH THE COMPANY.

         11. NO RIGHT TO CONTINUED SERVICE RELATIONSHIP. Nothing contained in
the Option shall: (i) confer upon the Consultant any right with respect to the
continuance of Consultant's service relationship with the Company, or with any
Parent or Subsidiary corporation of the Company, or (ii) limit in any way the
right of the Company, or of any Parent or Subsidiary corporation, to terminate
the Consultant's service relationship at any time. Except to the extent the
Company and the Consultant shall have otherwise agreed in writing, Consultant's
service relationship shall be terminable by the Company (or by a Parent or
Subsidiary corporation, if applicable) at will. Subject to Section 12, the Board
in its sole discretion shall determine whether any leave of absence or
interruption in the service relationship (including an interruption during
military service) shall be deemed a termination of Consultant's service
relationship for the purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Consultant's service
relationship shall not be deemed to terminate if the Consultant takes any
military leave, sick leave, or other bona fide leave of absence approved by the
Company, of ninety (90) days or less. In the event of a leave in excess of
ninety (90) days, the Consultant's service relationship shall be deemed to
terminate on the ninety-first

Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 10


(91st) day of the leave unless the Consultant's
right to reinstate Consultant's service relationship remains guaranteed by
statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as a service
relationship for purposes of Section 3 if and only if the leave of absence is
designated by the Company as (or required by law to be) a leave for which
vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Consultant acknowledges receipt of
a copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Consultant represents that the Consultant is familiar with the terms and
conditions of the Plan, and hereby accepts the Option subject to all of the
terms and conditions thereof, which terms and conditions shall control to the
extent inconsistent in any respect with the provisions herein or in the Option
Agreement. The Consultant hereby agrees to accept as binding, conclusive and
final all decisions and interpretations of the Board as to any questions arising
under the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option may be required or may desire to serve on the other
party to the Option Agreement in connection with the Option Agreement shall be
in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be
deemed complete on the date of actual delivery as shown by the addressee's
registry or certification receipt or at the expiration of the third (3rd)
business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Consultant shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Consultant shall deliver such Common Stock
endorsed in blank or accompanied by Stock Assignments Separate from Certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Consultant of the Common Stock to


<PAGE>   116


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 11

the Company (or its assignees) shall be made free of any and all claims,
encumbrances, liens and restrictions of every kind, other than those imposed
hereunder.

         17. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Consultant and the Consultant's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.


         18. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Consultant.

         19. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Consultant and
the Company with respect to the subject matter contained therein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Consultant and the Company other than those set forth or provided
therein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         20. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         21. INDEPENDENT TAX ADVICE. The Consultant agrees that the Consultant
has obtained or will obtain the advice of independent tax counsel (or has
determined not to obtain such advice, having had adequate opportunity to do so)
regarding the federal and state income tax consequences of the receipt and
exercise of the Option and of the disposition of Common Stock acquired upon
exercise of the Option, including advice regarding the imposition of the
alternative minimum tax which may result from items of tax preference, and
regarding holding period requirements for preferential tax treatment. The
Consultant acknowledges that the Consultant has not relied and will not rely
upon any advice or representation by the Company or by its employees or
representatives with respect to the tax treatment of the Option.

         22. INDEPENDENT CONTRACTOR: INDEMNITY BY THE CONSULTANT. The Consultant
agrees that in performing services for the Company, the Consultant is acting as
an independent contractor. As such, the Consultant waives any claim of rights to
payment by the Company of Social Security Taxes, Income Tax Withholding,
Worker's Compensation, Unemployment Compensation, or like benefits normally

                 CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT


Portola Packaging, Inc.
898 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of ___________________, ________________, my
stock option (granted ________________) to purchase _________________ shares
(the "Option Shares") of the Common Stock of Portola Packaging, Inc., a Delaware
corporation (the "Company"). Payment of the option price of $______________ is
attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares and I live. In addition, I understand that if I am an
affiliate of the Company, I will not be permitted to

<PAGE>   120


Portola Packaging, Inc.
Page 2


resell solely under the Registration Statement any Option Shares purchased under
the Plan, and that such resales must be registered in a separate registration
statement or be effected in accordance with Rule 144 or another available
exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
result of my purchase or disposition of the Option Shares. I represent that I
have consulted with any tax consultant(s) I deem advisable in connection with
the purchase or disposition of the Option Shares and that I am not relying on
the Company for any tax advice.

         IN WITNESS WHEREOF, the undersigned has executed this Notice of
Exercise as of the date set forth below.

                             PORTOLA PACKAGING, INC.
                 CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT
                                  OPTION TERMS
               (WITH ACCELERATION OF VESTING ON CHANGE OF CONTROL)


         THESE OPTION TERMS ("OPTION TERMS") ARE INCORPORATED INTO THAT CERTAIN
CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT ("OPTION AGREEMENT"), by and
between Portola Packaging, Inc., a Delaware corporation (the "COMPANY"), and the
Consultant (the "CONSULTANT") named in the Option Agreement and dated on the
"DATE OF GRANT" set forth therein.

                                 R E C I T A L S

         A. The Company has adopted and implemented its 1994 Stock Option Plan
(the "PLAN") permitting the grant of stock options to employees, officers,
directors, consultants and other independent contractors of the Company and its
Parent and Subsidiary corporations (as hereinafter defined), some of which are
intended to be non-statutory stock options in that they do not qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "INTERNAL REVENUE CODE"), to purchase
shares of the authorized but unissued Common Stock or treasury shares of the
Company ("COMMON STOCK"). The par value of the Company's Common Stock is as set
forth in the Option Agreement.

         B. The Board of Directors (or a duly authorized Committee thereof) of
the Company (in either case, referred to herein as the "BOARD") has authorized
the granting of a non-statutory stock option to Consultant, thereby allowing
Consultant to acquire an ownership interest (or increase Consultant's ownership
interest) in the Company.

                              O P T I O N  T E R M S

         1. GRANT OF STOCK OPTION. As set forth in the Option Agreement, the
Company has granted to Consultant a non-transferable and non-assignable option
to purchase the number of shares of the Company's Common Stock at the exercise
price set forth in the Option Agreement as adjusted and upon the terms and
conditions set forth herein (such purchase right being sometimes referred to
herein as "THE OPTION").

         2. TERM AND TYPE OF OPTION. Unless earlier terminated in accordance
with Sections 6 or 7.2 hereof, the Option and all rights of the Consultant to
purchase Common Stock thereunder shall expire with respect to all of the shares
then subject hereto at 5:00 p.m. Pacific time on the expiration date set forth
in the Option Agreement (the "EXPIRATION DATE"). The Option is a non-statutory
stock option in that it is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the Internal Revenue Code. Accordingly, the
Consultant understands that under current law, the Consultant will recognize
ordinary income for federal income tax purposes upon exercise of the Option in
an amount equal to the excess (if any) of the fair market value of the shares of
Common Stock so purchased


<PAGE>   125


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 2


over the exercise price paid for such shares. Consultant further understands
that Consultant must satisfy all applicable federal, state, local and foreign
income and employment tax withholding requirements at the date of exercise. Any
reference herein to "VESTED SHARES" shall mean those shares under the Option
which have vested in accordance with the Vesting Schedule set forth in the
Option Agreement.

         3. EXERCISE.

                  3.1 SCHEDULE. Subject to the remaining provisions herein, the
Option shall be exercisable as set forth in the Option Agreement.

                  3.2 CUMULATIVE NATURE OF EXERCISE SCHEDULE. The exercise dates
specified in the Option Agreement refer to the earliest dates on which the
Option may be exercised with respect to the stated percentages of the Common
Stock covered by the Option, and the Option may be exercised with respect to all
or any part of any such percentage of the total shares at any time on or after
such dates and prior to the Expiration Date (or any earlier termination of the
Option as provided herein). Except as provided in Section 6, Consultant must be
and remain in a service relationship with the Company, or with any parent or
subsidiary corporation of the Company (as defined in Internal Revenue Code
Sections 424(e) and (f)) (a "PARENT CORPORATION" and "SUBSIDIARY CORPORATION,"
respectively), during the entire period commencing with the Date of Grant of the
Option and ending with each of the periods appearing in the Option Agreement in
order to exercise the Option with respect to the shares applicable to any such
period. For purposes hereof "SERVICE RELATIONSHIP" shall mean being a duly
elected, acting corporate director, or an advisory board member, independent
contractor or employee. Except as otherwise expressly provided herein, the
Consultant's service relationship shall be deemed to have terminated upon an
actual termination of such service relationship and when any Parent or
Subsidiary corporation of the Company ceases to have such relationship with the
Company. Any references herein to Consultant's service relationship with the
Company shall be deemed to also refer to Consultant's service relationship with
any such Parent or Subsidiary corporation of the Company, as applicable.

                  3.3 OVERRIDING LIMITATION ON TIME FOR EXERCISE.
Notwithstanding any other provisions herein providing for a longer time to
exercise, the Option may not be exercised after the expiration of ten (10) years
from the Date of Grant.

         4. RIGHT OF FIRST REFUSAL. The Consultant and successors-in-interest to
Consultant shall not sell, assign, pledge or in any manner transfer any of the
shares of the Common Stock purchased hereunder, or any right or interest
therein, whether voluntarily or by operation of law, or by gift or otherwise,
except for a transfer which meets the requirements hereinafter set forth.

                  4.1 NOTICE OF PROPOSED SALE. If the Consultant desires to sell
or otherwise transfer any of Consultant's purchased shares of Common Stock, the
Consultant shall first give written notice thereof to the Company. The notice
shall name the proposed transferee, describe the relationship of such


<PAGE>   126

proposed transferee to the Consultant and state the number of shares to be
transferred, the proposed consideration and all other material terms and
conditions of the proposed transfer.

                  4.2 OPTION OF COMPANY TO REPURCHASE.

Section 4.3 below) shall have the option to elect to purchase some or all of the

notice were other than cash against delivery, the Company (or its assignees)
shall pay in cash or by check for said shares equal to the fair market value
thereof as determined in good faith by the Board, except that to the extent such
consideration is composed, in whole or in part, of promissory notes, the Company
(and its assignees) shall have the option of similarly issuing promissory notes
of like form, tenor and effect.

                           4.2.2 ARBITRATION OF VALUATION DISPUTE.
Notwithstanding the foregoing, in the event that the Consultant disagrees with
the determination of fair market value made by the Board, the Consultant shall
have the right to have such fair market value determined by arbitration in
accordance with the rules of the American Arbitration Association. The
arbitration shall be held in the county in which the Company has its executive
offices. The cost of arbitration shall be borne in equal shares by the Company
and the Consultant.

                           4.2.3 EXERCISE OF REPURCHASE OPTION. In the event the
Company (or its assignees) elects to purchase some or all of such shares, it
shall give written notice to the Consultant of its election and settlement for
such purchase of shares shall be made as provided below in Section 4.4.

                  4.3 ASSIGNABILITY OF COMPANY'S RIGHTS HEREUNDER. The Company
may at any time transfer and assign its rights and delegate its obligations
under this Section 4 to any other person, corporation, firm or entity, including

(or its assignees) elects to acquire some or all of the shares of the Consultant
as specified in the Consultant's notice, the Secretary of the Company shall so
notify the Consultant within forty-five (45) days after receipt of the
Consultant's notice, and settlement thereof shall be made by cash or Company
check not later than forty- five (45) days after the date the Secretary of the
Company gives the Consultant notice of the Company's election.

                  4.5 TRANSFERRED SHARES REMAIN SUBJECT TO RESTRICTIONS. In the
event the Company (or its assignees) does not elect to acquire all of the shares
specified in the Consultant's notice, the Consultant may, within the sixty (60)

period for electing to exercise the purchase rights granted to the Company (and
its assignees) in Section 4.2,transfer the shares in the manner specified in
Consultant's notice. In that event, the transferee, assignee or other recipient

subject to the provisions of this Section 4 (and also subject to any other
applicable provisions hereof) and shall execute such documentation as may be
requested by the Company, including, but not limited to, the form of Notice of
Exercise attached hereto as Exhibit "A" (the "NOTICE OF EXERCISE").

                  4.6 EXCEPTIONS TO FIRST REFUSAL RIGHTS. Anything to the
contrary contained herein notwithstanding, the transactions set forth herein
shall be exempt from the provisions of this Section 4 (provided that the
transferee shall first agree in writing, satisfactory to the Company, to be
bound by the terms and provisions of Sections 4, 5, 7, 10 and 13-21 hereof). In
this regard, the Consultant's transfer of any or all shares held subject to the
Option (either during the Consultant's lifetime or on death by will or the laws
of intestacy) to the Consultant's "Immediate Family," as herein defined, or to
any custodian or trustee for the account of the Consultant or Consultant's
Immediate Family, shall be exempt from the provisions of this Section 4.
"IMMEDIATE FAMILY" as used herein shall mean the spouse, lineal descendants,
father, mother, brother, sister, niece or nephew of the Consultant.

                  4.7 WAIVERS BY THE COMPANY. The provisions of this Section 4
may be waived by the Company with respect to any transfer proposed by the
Consultant only by duly authorized action of its Board.

                  4.8 UNAUTHORIZED TRANSFERS VOID. Any sale or transfer, or
purported sale or transfer, of the Common Stock subject to the Option shall be
null and void unless the terms, conditions and provisions of this Section 4 are
strictly satisfied.

                  4.9 TERMINATION OF FIRST REFUSAL RIGHT. The foregoing right
of first refusal shall terminate upon the earlier of:

                           4.9.1 PUBLIC OFFERING. The date equity securities of
the Company are first offered and sold to the public generally pursuant to a
registration statement filed with, and declared effective by, the United States
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "SECURITIES ACT"); or

                           4.9.2 ACQUISITION OF THE COMPANY. Immediately prior
to the acquisition of all or substantially all of the business and assets of the
Company by an unaffiliated third party (as determined by the Board), whether by
merger, sale of outstanding stock or of the Company's assets, or otherwise,
where no express provision is made for the assignment and continuation of the
Company's rights hereunder by a new or successor corporation.

         5. AGREEMENT TO LOCK-UP IN THE EVENT OF PUBLIC OFFERING. In the event
of a public offering of the Company's Common Stock pursuant to a registration
statement declared effective by the SEC, if requested by the Company or by its
underwriters, the Consultant agrees not to sell, sell short, grant any option to
buy or otherwise dispose of the shares of Common Stock purchased pursuant to the
Option (except for any such shares which may be included in the registration)
for a period of up to one hundred eighty (180) days following the consummation
of such offering. The Company may impose stop-transfer instructions with respect
to the shares of the Common Stock subject to the foregoing restriction until the
end of said period. The Consultant shall be subject to this Section 5 provided
and only if the officers and directors of the Company are also subject to
similar arrangements.

         6. RIGHTS ON TERMINATION OF SERVICE RELATIONSHIP. Upon the termination
of Consultant's service relationship with the Company (and with any Parent or
Subsidiary corporation of the Company), the Consultant's right to exercise the
Option shall be limited in the manner set forth in this Section 6 (and the
Option shall terminate in the event not so exercised), and shall also be subject
to the limitation provided in Section 3.

                  6.1 DEATH. If the Consultant's service relationship is
terminated because of the death of the Consultant, the Consultant's estate may,
for a period of twelve (12) months following the date of such termination,
exercise the Option to the extent it was exercisable by the Consultant on the
date of such termination. The Consultant's estate shall mean the Consultant's
legal representative upon death or any person who acquires the right to exercise
the Option by reason of such death in accordance with Section 8.2.

                  6.2 RETIREMENT. If the Consultant's service relationship is
terminated by voluntary retirement at or after reaching sixty-five (65) years of
age, the Consultant may, within three (3) months following such termination,
exercise the Option to the extent it was exercisable by the Consultant on the
date of such termination unless the Consultant dies prior to the expiration of
such period, in which event the Consultant shall be treated as though the
Consultant had died on the date of retirement and the provisions of Section 6.1
shall apply.

                  6.3 DISABILITY. If the Consultant's service relationship is
terminated because of a disability, the Consultant may, within twelve (12)
months following the date of such termination, exercise the Option to the extent
it was exercisable by the Consultant on the date of such termination unless the
Consultant dies prior to the expiration of such period, in which event the
Consultant shall be treated as though Consultant's death occurred on the date of
termination due to such disability and the provisions of Section 6.1 shall
apply.

                  6.4 TERMINATION FOR CAUSE. If the Consultant's service
relationship is terminated for cause, the Option shall expire on Consultant's
termination date or at such later time and on such conditions as determined by
the Board. For purposes of this paragraph, "cause" shall be defined as the


<PAGE>   129


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 6

willful breach or habitual neglect of the duties which Consultant is required to
perform by the Company, or any act of dishonesty, fraud, misrepresentation or
other acts of moral turpitude as would prevent the effective performance of
Consultant's duties.

                  6.5 OTHER TERMINATION. If the Consultant's service
relationship is terminated for any reason other than provided in Sections 6.1,
6.2, 6.3 and 6.4 above, the Consultant or the Consultant's estate may, within
three (3) months after the date of Consultant's termination, exercise the Option
to the extent it was exercisable by the Consultant on the date of such
termination.

                  6.6 TRANSFER OF SERVICE RELATIONSHIP TO RELATED CORPORATION.
In the event the Consultant leaves a service relationship with the Company to
enter a service relationship with any Parent or Subsidiary corporation of the
Company or if the Consultant leaves a service relationship with any Parent or
Subsidiary corporation to enter a consulting relationship with the Company or of
another such Parent or Subsidiary corporation of the Company, the Consultant
shall be deemed to continue in such service relationship with the Company for
all purposes of the Option.

                  6.7 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth above is prevented because the issuance of shares upon such exercise
would constitute a violation of any applicable federal, state or foreign
securities law or other law or regulation, the Option shall remain exercisable
only as to shares otherwise purchasable at such time until three (3) months
after the date the Consultant is notified by the Company that the Option is
exercisable, but in any event no later than the expiration of ten (10) years
from the Date of Grant. The Company makes no representation as to the tax
consequences of any such delayed exercise. The Consultant should consult with
the Consultant's own tax advisor as to the tax consequences to the Consultant of
any such delayed exercise.

                  6.8 EXTENSION IF CONSULTANT IS SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods for
exercise of the Option set forth in Section 6 of shares acquired upon the
exercise of the Option would subject the Consultant to liability under Section
16(b) of the Securities Exchange Act of 1934, as amended, the Option shall
remain exercisable as to shares purchasable at the date of termination of
Consultant's service relationship until the earliest to occur of (i) the tenth
(10th) day following the date on which a sale of such shares by the Consultant
would no longer be subject to such liability, (ii) the one hundred ninetieth
(190th) day after the termination of Consultant's service relationship, or (iii)
the Expiration Date.

         7. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

                  7.1 STOCK SPLITS AND SIMILAR EVENTS; RECLASSIFICATIONS. The
number of shares of Common Stock covered by the Option and the exercise price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued and outstanding shares of Common Stock resulting


<PAGE>   130


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 7

from a subdivision or combination of such shares or the payment of a stock
dividend (but only on the Common Stock) or a recapitalization or any other
increase or decrease in the number of such outstanding shares of Common Stock
effected without the receipt of consideration by the Company; provided, however,
that the conversion of any convertible securities of the Company shall not be
deemed to have been "effected without receipt of consideration." In the event
that the shares of Common Stock covered by the Option are reclassified by the
Company, other than pursuant to a transaction described in Section 7.2, then the
Option shall apply to the appropriate number of shares of newly classified
Common Stock designated by the Board.

                  7.2 MERGERS AND ACQUISITIONS. Subject to any required action
by the Company's Board and stockholders, if the Company shall be a constituent
corporation in any merger or consolidation, provided the Option is not
terminated as set forth below in Section 7.3 upon consummation of such merger or
consolidation, this Option shall pertain and apply to the securities or other
property to which a holder of the number of shares subject to the unexercised
portion of this Option would have been entitled upon such consummation.

                  7.3 CHANGE OF CONTROL. In the event of a Change of Control (as
defined below), this Option shall become immediately exercisable in full as of
the date thirty (30) days prior to the consummation of such Change of Control.
The exercise or vesting that was permissible solely by reason of this Section
shall be conditioned upon the consummation of the Change of Control.
Furthermore, the Board, in its sole discretion, may arrange with the surviving,
continuing, successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "ACQUIRING CORPORATION"), for the Acquiring Corporation
to assume the Company's rights and obligations under outstanding Options (which,
for purposes of this Section 7.3, shall include Options that have become
immediately exercisable and fully vested as provided above) not exercised by the
Consultant prior to the consummation of the Change of Control or substitute
options for the Acquiring Corporation's stock for such outstanding Options. Any
Options which are neither assumed nor substituted for by the Acquiring
Corporation in connection with the Change of Control nor exercised prior to the
consummation of the Change of Control shall terminate and cease to be
outstanding as of the effective date of the Change of Control. A "CHANGE OF
CONTROL" shall be deemed to have occurred in the event any of the following
occurs with respect to the Company:

                           7.3.1 the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange.

                           7.3.2 a merger or consolidation in which the Company
is not the surviving corporation, other than (i) a merger in which the
stockholders of the Company before such merger or consolidation retain directly
or indirectly, at least a majority of the voting stock of the surviving

<PAGE>   131


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 8


corporation or the parent corporation of the surviving corporation and the
options are assumed or substituted by the surviving corporation which assumption
or substitution shall be binding on the Consultant, or (ii) a merger or
consolidation with a wholly-owned subsidiary, a reincorporation of the Company
in a different jurisdiction, or other transaction in which there is no
substantial change in the stockholders of the Company and the Options are
assumed or substituted by the Acquiring Corporation, which assumption or
substitution shall be binding on the Consultant.

                           7.3.3 a merger or consolidation in which the Company
is the surviving corporation where the stockholders of the Company before such
merger or consolidation do not retain, directly or indirectly, at least a
majority of the voting stock of the Company after such merger or consolidation.

                           7.3.4 the sale, exchange or transfer of all or
substantially all of the assets of the Company, other than a sale, exchange or
transfer to one or more subsidiaries of the Company.

                           7.3.5 a liquidation or dissolution of the Company.

                           7.3.6 any other transaction which qualifies as a
"corporate transaction" under Section 424 of the Internal Revenue Code wherein
the stockholders of the Company give up all of their equity interest in the
Company (except for the acquisition, sale or transfer of all or substantially
all of the outstanding shares of the Company).

                  7.4 BOARD'S DETERMINATION FINAL AND BINDING UPON CONSULTANT.
To the extent that the foregoing adjustments in this Section 7 relate to stock
or securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. The
Company agrees to give notice of any such adjustment to the Consultant;
provided, however, that any such adjustment shall be effective and binding for
all purposes hereof whether or not such notice is given or received.

                  7.5 NO RIGHTS EXCEPT AS EXPRESSLY STATED. Except as
hereinabove expressly provided in this Section 7, no additional rights shall
accrue to the Consultant by reason of any subdivision or combination of shares
of the capital stock of any class or the payment of any stock dividend or any
other increase or decrease in the number of shares of any class or by reason of
any dissolution, liquidation, merger or consolidation or spin-off of assets or
of stock of another corporation, and any issue by the Company of shares of stock
of any class or of securities convertible into shares of stock of any class
shall not affect, and no adjustment by reason thereof shall be made with respect
to, the number or exercise price of shares subject to the Option. Neither the
Consultant nor any person claiming under or through the Consultant shall be, or
have any of the rights or privileges of, a shareholder of the Company in respect
of any of the shares issuable upon the exercise of the Option,


<PAGE>   132


Portola Packaging, Inc.
Option Terms
Consultant Non-Statutory Stock Option Agreement
Page 9


unless and until the Option is properly and lawfully exercised and a certificate
representing the shares so purchased is duly issued and delivered to the
Consultant or to Consultant's estate.

                  7.6  NO LIMITATIONS ON COMPANY'S DISCRETION. The grant of the
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge or consolidate or to dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         8. MANNER OF EXERCISE.

                  8.1 GENERAL INSTRUCTIONS FOR EXERCISE. The Option shall be
exercised by the Consultant by completing, executing and delivering to the
Company the Notice of Exercise specifying the number of shares of Common Stock
which the Consultant elects to purchase. The Company's obligation to deliver
shares upon the exercise of the Option shall be subject to the Consultant's
satisfaction of all applicable federal, state, local and foreign income and
employment tax withholding requirements, if any. Upon receipt of such Notice of
Exercise and of payment of the purchase price (and payment of applicable taxes
as provided above), the Company shall, as soon as reasonably possible and
subject to all other provisions hereof, deliver certificates for the shares of
Common Stock so purchased, registered in the Consultant's name or in the name of
Consultant's legal representative (if applicable). Payment of the purchase price
upon any exercise of the Option shall be made by check acceptable to the Company
or in cash; provided, however, that the Board may, in its sole and absolute
discretion, accept any other legal consideration to the extent permitted under
applicable laws and the Plan.

                  8.2 EXERCISE PROCEDURE AFTER DEATH. To the extent exercisable
after Consultant's death, the Option shall be exercised only by Consultant's
executor(s) or administrator(s) or the person or persons duly authorized, or to
whom the Option is transferred under Consultant's will or, if Consultant shall
fail to make testamentary disposition of the Option, under the applicable laws
of descent and distribution. Any such transferee exercising the Option must
furnish the Company with (i) written Notice of Exercise and relevant information
as to Consultant's status, (ii) evidence satisfactory to the Company to
establish the validity of the transfer of the Option and compliance with any
laws or regulations pertaining to said transfer, and (iii) written acceptance of
the terms and conditions of the Option as contained herein.

         9. NON-TRANSFERABLE. The Option shall, during the lifetime of the
Consultant, be exercisable only by the Consultant and shall not be transferable
or assignable by the Consultant in whole or in part other than by will or the
laws of descent and distribution. If the Consultant shall make any such
purported transfer or assignment of the Option, such assignment shall be null
and void and of no force or effect whatsoever.

Consultant Non-Statutory Stock Option Agreement
Page 10


         10. COMPLIANCE WITH SECURITIES AND OTHER LAWS. The Option may not be
exercised and the Company shall not be obligated to deliver any certificates
evidencing shares of Common Stock thereunder if the issuance of shares upon such
exercise would constitute a violation of any applicable requirements of: (i) the
Securities Act, (ii) the Securities Exchange Act of 1934, as amended, (iii)
applicable state securities laws, (iv) any applicable listing requirement of any
stock exchange on which the Company's Common Stock is then listed, and (v) any
other law or regulation applicable to the issuance of such shares. Nothing
herein shall be construed to require the Company to register or qualify any
securities under applicable federal or state securities laws, or to take any
action to secure an exemption from such registration and qualification for the
issuance of any securities upon the exercise of the Option. Shares of Common
Stock issued upon exercise of the Option shall include the following legends and
such other legends as in the opinion of the Company's counsel may be required by
applicable federal, state and foreign securities laws:

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
         RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A STOCK
         OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS INCORPORATED INTO SUCH
         STOCK OPTION AGREEMENT, DATED _________________, A COPY OF WHICH IS ON
         FILE WITH THE COMPANY.

         11. NO RIGHT TO CONTINUED SERVICE RELATIONSHIP. Nothing contained in
the Option shall: (i) confer upon the Consultant any right with respect to the
continuance of Consultant's service relationship with the Company, or with any
Parent or Subsidiary corporation of the Company, or (ii) limit in any way the
right of the Company, or of any Parent or Subsidiary corporation, to terminate
the Consultant's service relationship at any time. Except to the extent the
Company and the Consultant shall have otherwise agreed in writing, Consultant's
service relationship shall be terminable by the Company (or by a Parent or
Subsidiary corporation, if applicable) at will. Subject to Section 12, the Board
in its sole discretion shall determine whether any leave of absence or
interruption in the service relationship (including an interruption during
military service) shall be deemed a termination of Consultant's service
relationship for the purposes hereof.

         12. LEAVE OF ABSENCE. For purposes hereof, the Consultant's service
relationship shall not be deemed to terminate if the Consultant takes any
military leave, sick leave, or other bona fide leave of absence approved by the
Company, of ninety (90) days or less. In the event of a leave in excess of
ninety (90) days, the Consultant's service relationship shall be deemed to
terminate on the ninety-first (91st) day of the leave unless the Consultant's
right to reinstate Consultant's service relationship remains guaranteed by
statute or contract or applicable law requires otherwise. Notwithstanding the
foregoing, however, a leave of absence shall be treated as a service
relationship for purposes of Section 3 if and only if the leave of absence is
designated by the Company as (or required by law to be) a leave for which
vesting credit is given.

         13. COMMITTEE OF THE BOARD. In the event that the Plan is administered
by a committee of the Board (the "COMMITTEE"), all references herein to the
Board shall be construed to mean the Committee for the period(s) during which
the Committee administers the Plan.

         14. OPTION SUBJECT TO TERMS OF PLAN. In addition to the provisions
hereof, these Option Terms and the Option Agreement are governed by, and subject
to the terms and conditions of, the Plan. The Consultant acknowledges receipt of
a copy of the Plan (a copy of which is attached hereto as Exhibit "B"). The
Consultant represents that the Consultant is familiar with the terms and
conditions of the Plan, and hereby accepts the Option subject to all of the
terms and conditions thereof, which terms and conditions shall control to the
extent inconsistent in any respect with the provisions herein or in the Option
Agreement. The Consultant hereby agrees to accept as binding, conclusive and
final all decisions and interpretations of the Board as to any questions arising
under the Plan, these Option Terms or the Option Agreement.

         15. NOTICES. All notices and other communications of any kind which
either party to the Option may be required or may desire to serve on the other
party to the Option Agreement in connection with the Option Agreement shall be
in writing and may be delivered by personal service or by registered or
certified mail, return receipt requested, deposited in the United States mail
with postage thereon fully prepaid, addressed to the other party at the
addresses indicated in the Option Agreement or as otherwise provided below.
Service of any such notice or other communication so made by mail shall be
deemed complete on the date of actual delivery as shown by the addressee's
registry or certification receipt or at the expiration of the third (3rd)
business day after the date of mailing, whichever is earlier in time. Either
party may from time to time, by notice in writing served upon the other as
aforesaid, designate a different mailing address or a different person to which
such notices or other communications are thereafter to be addressed or
delivered.

         16. FURTHER ASSURANCES. The Consultant shall, upon request of the
Company, take all actions and execute all documents requested by the Company
which the Company deems to be reasonably necessary to effectuate the terms and
intent of the Option and these Option Terms and, when required by any provision
herein to transfer all or any portion of the Common Stock purchased hereunder to
the Company (or its assignees), the Consultant shall deliver such Common Stock
endorsed in blank or accompanied by Stock Assignments Separate from Certificate
duly endorsed in blank, so that title thereto will pass by delivery alone. Any
sale or transfer by the Consultant of the Common Stock to the Company (or its
assignees) shall be made free of any and all claims, encumbrances, liens and
restrictions of every kind, other than those imposed hereunder.

         17. SUCCESSORS. Except to the extent the same is specifically limited
by the terms and provisions herein, the Option Agreement (as supplemented by the
Plan and these Option Terms) is binding upon the Consultant and the Consultant's
successors, heirs and personal representatives, and upon the Company, its
successors and assigns.

         18. TERMINATION OR AMENDMENT. Subject to the terms and conditions of
the Plan, the Board may terminate or amend the Plan or the Option Agreement and
these Option Terms at any time; provided, however, that no such termination or
amendment may adversely affect the Option or any unexercised portion thereof
without the consent of the Consultant.

         19. INTEGRATED AGREEMENT. The Option Agreement, these Option Terms and
the Plan constitute the entire understanding and agreement of the Consultant and
the Company with respect to the subject matter contained therein, and there are
no agreements, understandings, restrictions, representations, or warranties
between the Consultant and the Company other than those set forth or provided
therein. To the extent contemplated herein, the provisions herein shall survive
any exercise of the Option and shall remain in full force and effect.

         20. OTHER MISCELLANEOUS TERMS. Titles and captions contained herein are
inserted only as a matter of convenience and for reference, and in no way
define, limit, extend or describe the scope of these Option Terms or the intent
of any provision hereof. The Option Agreement, these Option Terms and the Plan
shall be governed by and construed in accordance with the laws of the State of
California, irrespective of its choice of law principles.

         21. INDEPENDENT TAX ADVICE. The Consultant agrees that the Consultant
has obtained or will obtain the advice of independent tax counsel (or has
determined not to obtain such advice, having had adequate opportunity to do so)
regarding the federal and state income tax consequences of the receipt and
exercise of the Option and of the disposition of Common Stock acquired upon
exercise of the Option, including advice regarding the imposition of the
alternative minimum tax which may result from items of tax preference, and
regarding holding period requirements for preferential tax treatment. The
Consultant acknowledges that the Consultant has not relied and will not rely
upon any advice or representation by the Company or by its employees or
representatives with respect to the tax treatment of the Option.

         22. INDEPENDENT CONTRACTOR: INDEMNITY BY THE CONSULTANT. The Consultant
agrees that in performing services for the Company, the Consultant is acting as
an independent contractor. As such, the Consultant waives any claim of rights to
payment by the Company of Social Security Taxes, Income Tax Withholding,
Worker's Compensation, Unemployment Compensation, or like benefits normally
afforded employees of the Company and agrees that Consultant alone shall be
responsible for paying said obligations.

                 CONSULTANT NON-STATUTORY STOCK OPTION AGREEMENT


Portola Packaging, Inc.
898 Faulstich Court
San Jose, CA  95113
Attn:  Corporate Secretary

         Re:      Notice of Exercise of Stock Option

Ladies and Gentlemen:

         I hereby exercise, as of ___________________, ________________, my
stock option (granted ________________) to purchase _________________ shares
(the "Option Shares") of the Common Stock of Portola Packaging, Inc., a Delaware
corporation (the "Company"). Payment of the option price of $______________ is
attached to this notice.

         I understand that to the extent deemed necessary by the Company's
counsel, the certificate(s) representing the Option Shares, whether upon initial
issuance or any transfer thereof, shall bear on their reverse such legends,
prominently stamped or printed thereon in capital letters, as in the opinion of
the Company's counsel may be required by applicable federal, state and foreign
securities laws, the 1994 Stock Option Plan (the "Plan") and applicable option
agreements thereunder, including the following:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  RESTRICTIONS ON TRANSFER AND OTHER AGREEMENTS CONTAINED IN A
                  STOCK OPTION AGREEMENT AND IN THOSE STOCK OPTION TERMS
                  INCORPORATED INTO SUCH STOCK OPTION AGREEMENT, DATED
                  ____________, A COPY OF WHICH IS ON FILE WITH THE COMPANY.

         I further understand that in the event I propose to sell, pledge or
otherwise transfer any Option Shares to any person or entity, including, without
limitation, any stockholder of the Company, the Company shall have the right to
repurchase the Option shares under the terms and subject to the conditions set
forth in Section 4 of the Option Terms.

         I further understand that currently no "public market" exists for the
Company's Common Stock and there can be no assurance such a public market will
develop in the future. Accordingly, the Option Shares I purchase under the Plan
may have to be held by me indefinitely notwithstanding the registration of such
shares. Although the registration statement filed by the Company with the
Securities and Exchange Commission with respect to the Option Shares (the
"Registration Statement") satisfies most federal securities laws requirements
with respect to the resale of the Option Shares, such shares may be subject to
resale restrictions imposed by securities laws in the state(s) where any
purchaser of my shares and I live. In addition, I understand that if I am an
affiliate of the Company, I will not be permitted to

<PAGE>   138


Portola Packaging, Inc.
Page 2


resell solely under the Registration Statement any Option Shares purchased under
the Plan, and that such resales must be registered in a separate registration
statement or be effected in accordance with Rule 144 or another available
exemption under the Securities Act of 1933, as amended.

         I further understand that I may suffer adverse tax consequences as a
