shares acquired upon the exercise thereof, including, without limitation, (i)

all other terms, conditions and restrictions applicable to the Option or such

                           (d) to approve one or more forms of Option Agreement;

                           (e) to amend, modify, extend, or renew, or grant a
new Option in substitution for, any Option or to waive any restrictions or

                           (f) to accelerate, continue, extend or defer the
exercisability of any Option or the vesting of any shares acquired upon the

termination of employment or service with the Participating Company Group;

                           (g) to prescribe, amend or rescind rules, guidelines

                                       3
<PAGE>   4
without limitation, as the Board deems necessary or desirable to comply with the
laws of, or to accommodate the tax policy or custom of, foreign jurisdictions
whose citizens may be granted Options; and

                           (h) to correct any defect, supply any omission or
reconcile any inconsistency in the Plan or any Option Agreement and to make all
other determinations and take such other actions with respect to the Plan or any
Option as the Board may deem advisable to the extent consistent with the Plan
and applicable law.

         4.       SHARES SUBJECT TO PLAN.

                  4.1 MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment
as provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be One Hundred Thousand (100,000) and shall
consist of authorized but unissued or reacquired shares of Stock or any
combination thereof. If an outstanding Option for any reason expires or is
terminated or canceled or shares of Stock acquired, subject to repurchase, upon
the exercise of an Option are repurchased by the Company, the shares of Stock
allocable to the unexercised portion of such Option, or such repurchased shares
of Stock, shall again be available for issuance under the Plan.

                  4.2 ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event
of any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments shall be made in the number and class of shares
subject to the Plan and to any outstanding Options, and in the exercise price
per share of any outstanding Options. If a majority of the shares which are of
the same class as the shares that are subject to outstanding Options are
exchanged for, converted into, or otherwise become (whether or not pursuant to
an Ownership Change Event, as defined in Section 8.1) shares of another
corporation (the "NEW SHARES"), the Board may unilaterally amend the outstanding
Options to provide that such Options are exercisable for New Shares. In the
event of any such amendment, the number of shares subject to, and the exercise
price per share of, the outstanding Options shall be adjusted in a fair and
equitable manner as determined by the Board, in its sole discretion.
Notwithstanding the foregoing, any fractional share resulting from an adjustment
pursuant to this Section 4.2 shall be rounded up or down to the nearest whole
number, as determined by the Board, and in no event may the exercise price of
any Option be decreased to an amount less than the par value, if any, of the
stock subject to the Option. The adjustments determined by the Board pursuant to
this Section 4.2 shall be final, binding and conclusive.

         5.       ELIGIBILITY AND OPTION LIMITATIONS. Options may be granted
only to Employees and Consultants; provided, however, that no Option shall be
granted any person whose eligibility to receive an Option under the Plan at the
time of grant would require the approval of the Company's stockholders pursuant
to any applicable law, regulation or rule, including, without limitation, the
rules applicable to the listing of the Company's securities on the Nasdaq
National Market System. For purposes of the foregoing sentence, "Employees"
shall include prospective Employees to whom Options are granted in connection
with written offers of employment with the Participating Company Group, and
"Consultants" shall include prospective Consultants to
<PAGE>   5
whom Options are granted in connection with written offers of engagement with
the Participating Company Group. Eligible persons may be granted more than one
(1) Option.

         6.       TERMS AND CONDITIONS OF OPTIONS. Options shall be evidenced by
Option Agreements specifying the number of shares of Stock covered thereby, in
such form as the Board shall from time to time establish. Option Agreements may
incorporate all or any of the terms of the Plan by reference and shall comply
with and be subject to the following terms and conditions:

                  6.1 EXERCISE PRICE. The exercise price for each Option shall
be established in the sole discretion of the Board; provided, however, that the
exercise price per share for an Option shall be not less than the Fair Market
Value of a share of Stock on the effective date of grant of the Option.
Notwithstanding the foregoing, an Option may be granted with an exercise price
lower than the minimum exercise price set forth above if such Option is granted
pursuant to an assumption or substitution for another option in a manner
qualifying under the provisions of Section 424(a) of the Code.

                  6.2 EXERCISE PERIOD. Options shall be exercisable at such time
or times, or upon such event or events, and subject to such terms, conditions,
performance criteria, and restrictions as shall be determined by the Board and
set forth in the Option Agreement evidencing such Option; provided, however,
that no Option granted to a prospective Employee or prospective Consultant may
become exercisable prior to the date on which such person commences service with
a Participating Company.

                  6.3 PAYMENT OF EXERCISE PRICE.

                           (a) FORMS OF CONSIDERATION AUTHORIZED. Except as
otherwise provided below, payment of the exercise price for the number of shares
of Stock being purchased pursuant to any Option shall be made (i) in cash, by
check, or cash equivalent, (ii) by tender to the Company of shares of Stock
owned by the Optionee having a Fair Market Value (as determined by the Company
without regard to any restrictions on transferability applicable to such stock
by reason of federal or state securities laws or agreements with an underwriter
for the Company) not less than the exercise price, (iii) by the assignment of
the proceeds of a sale or loan with respect to 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) (a
"CASHLESS EXERCISE"), (iv) by the Optionee's promissory note in a form approved
by the Company, (v) by such other consideration as may be approved by the Board
from time to time to the extent permitted by applicable law, or (vi) by any
combination thereof. The Board may at any time or from time to time, by adoption
of or by amendment to the standard forms of Option Agreement described in
Section 7, or by other means, grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or
which otherwise restrict one or more forms of consideration.

                           (b) TENDER OF STOCK. Notwithstanding the foregoing,
an Option may not be exercised by tender to the Company of shares of Stock to
the extent such tender of Stock would constitute a violation of the provisions
of any law, regulation or agreement restricting the

                                       5
<PAGE>   6
redemption of the Company's stock. Unless otherwise provided by the Board, an
Option may not be exercised by tender to the Company of shares of Stock unless
such shares either have been owned by the Optionee for more than six (6) months
or were not acquired, directly or indirectly, from the Company.

                           (c) CASHLESS EXERCISE. 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 a Cashless Exercise.

                           (d) PAYMENT BY PROMISSORY NOTE. No promissory note
shall be permitted if the exercise of an Option using a promissory note would be
a violation of any law. Any permitted promissory note shall be on such terms as
the Board shall determine at the time the Option is granted. The Board shall
have the authority to permit or require the Optionee to secure any promissory
note used to exercise an Option with the shares of Stock acquired upon the
exercise of the Option or with other collateral acceptable to the Company.
Unless otherwise provided by the Board, if the Company at any time is subject to
the regulations promulgated by the Board of Governors of the Federal Reserve
System or any other governmental entity affecting the extension of credit in
connection with the Company's securities, any promissory note shall comply with
such applicable regulations, and the Optionee shall pay the unpaid principal and
accrued interest, if any, to the extent necessary to comply with such applicable
regulations.

                  6.4 TAX WITHHOLDING. The Company shall have the right, but not
the obligation, to deduct from the shares of Stock issuable upon the exercise of
an Option, or to accept from the Optionee the tender of, a number of whole
shares of Stock having a Fair Market Value, as determined by the Company, equal
to all or any part of the federal, state, local and foreign taxes, if any,
required by law to be withheld by the Participating Company Group with respect
to such Option or the shares acquired upon the exercise thereof. Alternatively
or in addition, in its sole discretion, the Company shall have the right to
require the Optionee, through payroll withholding, cash payment or otherwise,
including by means of a Cashless Exercise, to make adequate provision for any
such tax withholding obligations of the Participating Company Group arising in
connection with the Option or the shares acquired upon the exercise thereof. The
Company shall have no obligation to deliver shares of Stock or to release shares
of Stock from an escrow established pursuant to the Option Agreement until the
Participating Company Group's tax withholding obligations have been satisfied by
the Optionee.

         7.       STANDARD FORM OF OPTION AGREEMENT.

                  7.1 GENERAL. Unless otherwise provided by the Board at the
time the Option is granted, an Option shall comply with and be subject to the
terms and conditions set forth in the form of Nonstatutory Stock Option
Agreement adopted by the Board concurrently with its adoption of the Plan and as
amended from time to time.

                  7.2 STANDARD TERM OF OPTIONS. Except as otherwise provided by
the Board in the grant of an Option, any Option granted hereunder shall have a
term of ten (10) years from the effective date of grant of the Option.

                                       6
<PAGE>   7
                  7.3 AUTHORITY TO VARY TERMS. The Board shall have the
authority from time to time to vary the terms of any standard form of Option
Agreement described in this Section 7 either in connection with the grant or
amendment of an individual Option or in connection with the authorization of a
new standard form or forms; provided, however, that the terms and conditions of
any such new, revised or amended standard form or forms of Option Agreement are
not inconsistent with the terms of the Plan.

         8.       TRANSFER OF CONTROL.

                  8.1 DEFINITIONS.

                           (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to
have occurred if any of the following occurs with respect to the Company:

                                    (i) the direct or indirect sale or exchange
in a single or series of related transactions by the stockholders of the Company
of more than fifty percent (50%) of the voting stock of the Company;

                                    (ii) a merger or consolidation in which the
Company is a party;

                                    (iii) the sale, exchange, or transfer of all
or substantially all of the assets of the Company; or

                                    (iv) a liquidation or dissolution of the
Company.

                           (b) A "TRANSFER OF CONTROL" shall mean an Ownership
Change Event or a series of related Ownership Change Events (collectively, the
"TRANSACTION") wherein the stockholders of the Company immediately before the
Transaction do not retain immediately after the Transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

                                       7
<PAGE>   8
                  8.2 EFFECT OF TRANSFER OF CONTROL ON OPTIONS. In the event of
an eligible Transfer of Control, each of the outstanding Options shall receive
an additional two (2) years of accelerated vesting as of the date ten (10) days
prior to the date of the Transfer of Control. The exercise or vesting of any
Option that was permissible solely by reason of this Section 8.2 shall be
conditioned upon the consummation of the Transfer of Control. In addition, the
surviving, continuing, successor, or purchasing corporation or parent
corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), may
either assume the Company's rights and obligations under outstanding Options or
substitute for outstanding Options substantially equivalent options for the
Acquiring Corporation's stock. For purposes of this Section 8.2, an Option shall
be deemed assumed if, following the Transfer of Control, the Option confers the
right to purchase in accordance with its terms and conditions, for each share of
Stock subject to the Option immediately prior to the Transfer of Control, the
consideration (whether stock, cash or other securities or property) to which a
holder of a share of Stock on the effective date of the Transfer of Control was
entitled. Any Options which are neither assumed or substituted for by the
Acquiring Corporation in connection with the Transfer of Control nor exercised
as of the date of the Transfer of Control shall terminate and cease to be
outstanding effective as of the date of the Transfer of Control. Notwithstanding
the foregoing, shares acquired upon exercise of an Option prior to the Transfer
of Control and any consideration received pursuant to the Transfer of Control
with respect to such shares shall continue to be subject to all applicable
provisions of the Option Agreement evidencing such Option except as otherwise
provided in such Option Agreement. Furthermore, notwithstanding the foregoing,
if the corporation the stock of which is subject to the outstanding Options
immediately prior to an Ownership Change Event described in Section 8.1(a)(i)
constituting a Transfer of Control is the surviving or continuing corporation
and immediately after such Ownership Change Event less than fifty percent (50%)
of the total combined voting power of its voting stock is held by another
corporation or by other corporations that are members of an affiliated group
within the meaning of Section 1504(a) of the Code without regard to the
provisions of Section 1504(b) of the Code, the outstanding Options shall not
terminate unless the Board otherwise provides in its sole discretion.

                  8.3 NOTICE. The Company shall send to all holders of
outstanding Options at least ten (10) days' written notice prior to the
consummation of a Transfer of Control. The Company's notice shall summarize the
principal terms of the Transfer of Control including, without limitation,
whether the Acquiring Corporation is assuming the outstanding Options or
substituting equivalent options therefor.

         9. PROVISION OF INFORMATION. Each Optionee shall be given access to
information concerning the Company equivalent to that information generally made
available to the Company's common stockholders.

         10. NONTRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee,
an Option shall be exercisable only by the Optionee or the Optionee's guardian
or legal representative. No Option shall be assignable or transferable by the
Optionee, except by will or by the laws of descent and distribution.

         11. INDEMNIFICATION. In addition to such other rights of
indemnification as they may have as members of the Board or officers or
employees of the Participating Company Group,

                                       8
<PAGE>   9
members of the Board and any officers or employees of the Participating Company
Group to whom authority to act for the Board is delegated shall be indemnified
by the Company against all reasonable expenses, including attorneys' fees,
actually and necessarily incurred in connection with the defense of any action,
suit or proceeding, or in connection with any appeal therein, to which they or
any of them may be a party by reason of any action taken or failure to act under
or in connection with the Plan, or any right granted hereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by independent legal counsel selected by the Company) or paid by them in
satisfaction of a judgment in any such action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit or
proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within sixty (60) days
after the institution of such action, suit or proceeding, such person shall
offer to the Company, in writing, the opportunity at its own expense to handle
and defend the same.

         12. TERMINATION OR AMENDMENT OF PLAN. The Board may terminate or amend
the Plan at any time. However, no termination or amendment of the Plan may
adversely affect any then outstanding Option or any unexercised portion thereof,
without the consent of the Optionee, unless such termination or amendment is
necessary to comply with any applicable law or government regulation.

         IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing P.F. Chang's China Bistro, Inc. 1999 Nonstatutory Stock
Option Plan was duly adopted by the Board on June 18, 1999.

               to distribution or, unless the Depositor otherwise directs,  used
               for  payment  of  redemptions  in excess of the  per-Unit  amount
               allocable to Units  tendered for  redemption.  As directed by the
               Depositor,  the  Trustee  will  advance  funds to the Trust in an

               distribution  to Unit  Holders  of  record  on such  dates as the
               Depositor   shall  direct,   provided   however,   that  no  such
               distribution  shall be made if the assets of the Trust subsequent
               to such  distribution  would not exceed any Deferred Sales Charge
               payable and other trust expenses."

          (iii) The second to the last paragraph of Section 3.08 Sale of
               Securities shall be amended to replace the word "equal" with the
