                                1997 STOCK PLAN

         1.       Purposes of the Plan. The purposes of this Stock Plan are to
attract and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees and Consultants of
the Company and its Subsidiaries and to promote the success of the Company's
business. Options granted under the Plan may be Incentive Stock Options or
Nonstatutory Stock Options, as determined by the Administrator at the time of
grant of an Option and subject to the applicable provisions of Section 422 of
the Code and the regulations promulgated thereunder. Stock Purchase Rights may
also be granted under the Plan.

upon expiration of a leave of absence approved by the Company is not so
guaranteed, on the 91st day of such leave any Incentive Stock Option held by

the preceding sentence, voting rights shall not be considered a benefit of
Share ownership.

         4.       Administration of the Plan.

                  (a)      Initial Plan Procedure. Prior to the date, if any,
upon which the Company becomes subject to the Exchange Act, the Plan shall be
administered by the Board or a Committee appointed by the Board.

                  (b)      Plan Procedure After the Date, if any, upon Which
the Company becomes Subject to the Exchange Act.

                           (i)      Multiple Administrative Bodies. If
permitted by Rule 16b-3, the Plan may be administered by different bodies with
respect to Directors, Officers and Employees who are neither Directors nor
Officers.

                           (ii)     Administration With Respect to Directors
and Officers. With respect to grants of Options and Stock Purchase Rights to
Employees who are also Officers or Directors of the Company, the Plan shall be
administered by (A) the Board if the Board may administer the Plan in
compliance with the rules under Rule 16b-3 promulgated under the Exchange Act
or any successor thereto ("Rule 16b-3") relating to the disinterested
administration of employee benefit plans under which Section 16(b) exempt
discretionary grants and awards of equity securities are to be made, or (B) a
Committee designated by the Board to administer the Plan, which Committee shall
be constituted to comply with the rules under Rule 16b-3 relating to the
disinterested administration of employee benefit plans under which Section
16(b) exempt discretionary grants and awards of equity securities are to be
made. Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by the rules under Rule 16b-3 relating to the disinterested
administration of employee benefit plans under which Section 16(b) exempt
discretionary grants and awards of equity securities are to be made.

                           (iii)    Administration With Respect to Other
Employees and Consultants . With respect to grants of Options and Stock
Purchase Rights to Employees or Consultants who are neither Directors nor
Officers of the Company, the Plan shall be administered by (A) the Board or (B)
a Committee designated by the Board, which committee shall be constituted in
such a manner as to satisfy Applicable Laws. Once appointed, such Committee
shall continue to serve in its designated capacity until otherwise directed by
the Board. From time to time the Board may increase the size of the Committee
and appoint additional members thereof, remove members (with or without cause)
and appoint new members in substitution therefor, fill vacancies, however
caused, and remove all members of the Committee and thereafter directly
administer the Plan, all to the extent permitted by the Applicable Laws.

                  (c)      Powers of the Administrator. Subject to the
provisions of the Plan and, in the case of a Committee, the specific duties
delegated by the Board to such Committee, and subject to the approval of any
relevant authorities, including the approval, if required, of any stock
exchange upon which the Common Stock is listed, the Administrator shall have
the authority in its discretion:

                           (i)      to determine the Fair Market Value of the
Common Stock, in accordance with Section 2(m) of the Plan;

                           (ii)     to select the Consultants and Employees to
whom Options and Stock Purchase Rights may from time to time be granted
hereunder;

                           (iii)    to determine whether and to what extent
Options and Stock Purchase Rights or any combination thereof are granted
hereunder;

                           (iv)     to determine the number of Shares to be
covered by each such award granted hereunder;

                           (v)      to approve forms of agreement for use under
the Plan;

                           (vi)     to determine the terms and conditions of
any award granted hereunder;

                           (vii)    to determine whether and under what
circumstances an Option may be settled in cash under subsection 9(f) instead of
Common Stock;

                           (viii)   to reduce the exercise price of any Option
to the then current Fair Market Value if the Fair Market Value of the Common
Stock covered by such Option has declined since the date the Option was
granted; and

                           (ix)     to construe and interpret the terms of the
Plan and awards granted pursuant to the Plan.

                  (d)      Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options or Stock Purchase
Rights.

         5.       Eligibility.

                  (a)      Nonstatutory Stock Options and Stock Purchase Rights
may be granted to Employees and Consultants. Incentive Stock Options may be
granted only to Employees. An Employee or Consultant who has been granted an
Option or Stock Purchase Right may, if otherwise eligible, be granted
additional Options or Stock Purchase Rights.

                  (b)      Each Option shall be designated in the written
option agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of the Shares with respect to which Incentive Stock
Options are exercisable for the first time by the Optionee during any calendar
year (under all plans of the Company and any Parent or Subsidiary) exceeds
$100,000, such Options shall be treated as Nonstatutory Stock Options. For
purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted. The Fair Market Value of the
Shares shall be determined as of the time the Option with respect to such
Shares is granted.

                  (c)      Neither the Plan nor any Option or Stock Purchase
Right shall confer upon any Optionee any right with respect to continuation of
his or her employment or consulting relationship with the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
his or her employment or consulting relationship at any time, with or without
cause.

                  (d)      Upon the Company or a successor corporation issuing
any class of common equity securities required to be registered under Section
12 of the Exchange Act or upon the Plan being assumed by a corporation having a


                                 Exhibit 4.3.4



<PAGE>   5

class of common equity securities required to be registered under Section 12 of
the Exchange Act, the following limitations shall apply to grants of Options
and Stock Purchase Rights to Employees:

                           (i)      The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization
as described in Section 12.

                           (ii)     If an Option or Stock Purchase Right is
cancelled in the same fiscal year of the Company in which it was granted (other
than in connection with a transaction described in Section 12), the cancelled
Option or Stock Purchase Right shall be counted against the limit set forth in
subsection (i) above. For this purpose, if the exercise price of an Option or
Stock Purchase Right is reduced, such reduction will be treated as a
cancellation of the Option or Stock Purchase Right and the grant of a new
Option or Stock Purchase Right.

         6.       Term of Plan. The Plan shall become effective upon the
earlier to occur of its adoption by the Board of Directors or its approval by
the shareholders of the Company, as described in Section 18 of the Plan. It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 14 of the Plan.

         7.       Term of Option. The term of each Option shall be the term
stated in the Option Agreement; provided, however, that the term shall be no
more than ten (10) years from the date of grant thereof. In the case of an
Incentive Stock Option granted to an Optionee who, at the time the Option is
granted, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Option shall be five (5) years from the date of grant thereof or
such shorter term as may be provided in the Option Agreement.

         8.       Option Exercise Price and Consideration.

                  (a)      The per share exercise price for the Shares to be
issued upon exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

                           (i)      In the case of an Incentive Stock Option

                                    (A)      granted to an Employee who, at the
time of grant of such Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                                    (B)      granted to any other Employee, the
per Share exercise price shall be no less than 100% of the Fair Market Value
per Share on the date of grant.

                           (ii)     In the case of a Nonstatutory Stock Option

                                    (A)      granted to a person who, at the
time of grant of such Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of the grant.

                                    (B)      granted to any other person, the
per Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant.

                  (b)      The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the method of payment, shall be
determined by the Administrator (and, in the case of an Incentive Stock Option,
shall be determined at the time of grant). Such consideration may consist of
(1) cash, (2) check, (3) promissory note, (4) other Shares which (x) in the
case of Shares acquired upon exercise of an Option, have been owned by the
Optionee for more than six months on the date of surrender, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which such Option shall be exercised, (5) delivery of a
properly executed exercise notice together with such other documentation as the
Administrator and a broker, if applicable, shall require to effect an exercise
of the


                                 Exhibit 4.3.5



<PAGE>   6

Option and delivery to the Company of the sale or loan proceeds required to pay
the exercise price, or (6) any combination of the foregoing methods of payment.
In making its determination as to the type of consideration to accept, the
Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

         9.       Exercise of Option.

                  (a)      Procedure for Exercise; Rights as a Shareholder. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, including performance criteria
with respect to the Company and/or the Optionee, and as shall be permissible
under the terms of the Plan.

                           An Option may not be exercised for a fraction of a
Share.

                           An Option shall be deemed to be exercised when
written notice of such exercise has been given to the Company in accordance
with the terms of the Option by the person entitled to exercise the Option and
full payment for the Shares with respect to which the Option is exercised has
been received by the Company. Full payment may, as authorized by the
Administrator, consist of any consideration and method of payment allowable
under Section 8(b) hereof. Until the issuance (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company) of the stock certificate evidencing such Shares, no right to vote,
receive dividends or any other rights as a shareholder shall exist with respect
to the Optioned Stock, notwithstanding the exercise of the Option. The Company
shall issue (or cause to be issued) such stock certificate promptly upon
exercise of the Option. No adjustment shall be made for a dividend or other
right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 12 hereof.

                           Exercise of an Option in any manner shall result in
a decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (b)      Termination of Employment or Consulting
Relationship. In the event of termination of an Optionee's Continuous Status as
an Employee or Consultant (but not in the event of an Optionee's change of
status from Employee to Consultant (in which case an Employee's Incentive Stock
Option shall automatically convert to a Nonstatutory Stock Option on the date
three (3) months and one day following such change of status) or from
Consultant to Employee), such Optionee may, but only within such period of time
as is determined by the Administrator, of at least thirty (30) days, with such
determination in the case of an Incentive Stock Option not exceeding three (3)
months after the date of such termination (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that the Optionee was
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

                  (c)      Disability of Optionee. In the event of termination
of an Optionee's Continuous Status as an Employee or Consultant as a result of
his or her disability, the Optionee may, but only within twelve (12) months
from the date of such termination (and in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination. If such disability is not a "disability" as such term is defined
in Section 22(e)(3) of the Code, in the case of an Incentive Stock Option such
Incentive Stock Option shall automatically cease to be treated as an Incentive
Stock Option and shall be treated for tax purposes as a Nonstatutory Stock
Option on the day three months and one day following such termination. To the
extent that the Optionee was not entitled to exercise the Option at the date of
termination, or if the Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

                  (d)      Death of Optionee. In the event of the death of an
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant) by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option on the date of


                                 Exhibit 4.3.6



<PAGE>   7

death. If, at the time of death, the Optionee was not entitled to exercise his
or her entire Option, the Shares covered by the unexercisable portion of the
Option shall immediately revert to the Plan. If, after the Optionee's death,
the Optionee's estate or a person who acquires the right to exercise the Option
by bequest or inheritance does not exercise the Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                  (e)      Rule 16b-3. Options granted to persons subject to
Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain
such additional conditions or restrictions as may be required thereunder to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

                  (f)      Buyout Provisions. The Administrator may at any time
offer to buy out for a payment in cash or Shares, an Option previously granted,
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10.      Non-Transferability of Options and Stock Purchase Rights.
Options and Stock Purchase Rights may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or
by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

         11.      Stock Purchase Rights.

                  (a)      Rights to Purchase. Stock Purchase Rights may be
issued either alone, in addition to, or in tandem with other awards granted
under the Plan and/or cash awards made outside of the Plan. After the
Administrator determines that it will offer Stock Purchase Rights under the
Plan, it shall advise the offeree in writing of the terms, conditions and
restrictions related to the offer, including the number of Shares that such
person shall be entitled to purchase, the price to be paid, and the time within
which such person must accept such offer, which shall in no event exceed thirty
(30) days from the date upon which the Administrator makes the determination to
grant the Stock Purchase Right. The offer shall be accepted by execution of a
Restricted Stock purchase agreement in the form determined by the
Administrator. Shares purchased pursuant to the grant of a Stock Purchase Right
shall be referred to herein as "Restricted Stock."

                  (b)      Repurchase Option. Unless the Administrator
determines otherwise, the Restricted Stock purchase agreement shall grant the
Company a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser's employment with the Company for any reason
(including death or disability). The purchase price for Shares repurchased
pursuant to the Restricted Stock purchase agreement shall be the original price
paid by the purchaser and may be paid by cancellation of any indebtedness of
the purchaser to the Company. The repurchase option shall lapse at such rate as
the Administrator may determine, but in no case at a rate of less than 20% per
year over five years from the date of purchase.

                  (c)      Other Provisions. The Restricted Stock purchase
agreement shall contain such other terms, provisions and conditions not
inconsistent with the Plan as may be determined by the Administrator in its
sole discretion. In addition, the provisions of Restricted Stock purchase
agreements need not be the same with respect to each purchaser.

                  (d)      Rights as a Shareholder. Once the Stock Purchase
Right is exercised, the purchaser shall have rights equivalent to those of a
shareholder and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the Stock Purchase Right is exercised, except as provided in
Section 12 of the Plan.

         12.      Adjustments Upon Changes in Capitalization or Merger.

                  (a)      Changes in Capitalization. Subject to any required
action by the shareholders of the Company, the number of shares of Common Stock
covered by each outstanding Option or Stock Purchase Right, and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options or Stock Purchase Rights have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option or Stock Purchase Right, as well as the price per share of Common Stock
covered by each such outstanding Option or Stock Purchase Right, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock


                                 Exhibit 4.3.7

resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock, or any other increase or decrease in
the number of issued shares of Common Stock effected without receipt of
consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

                  (b)      Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall
notify the Optionee at least fifteen (15) days prior to such proposed action.
To the extent it has not been previously exercised, the Option or Stock
Purchase Right shall terminate immediately prior to the consummation of such
proposed action.

                  (c)      Merger. In the event of a merger of the Company with
or into another corporation, each outstanding Option or Stock Purchase Right
may be assumed or an equivalent option or right may be substituted by such
successor corporation or a parent or subsidiary of such successor corporation.
If, in such event, an Option or Stock Purchase Right is not assumed or
substituted, the Option or Stock Purchase Right shall terminate as of the date
of the closing of the merger. For the purposes of this paragraph, the Option or
Stock Purchase Right shall be considered assumed if, following the merger, the
Option or Stock Purchase Right confers the right to purchase or receive, for
each Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger, the consideration (whether stock, cash, or
other securities or property) received in the merger by holders of Common Stock
for each Share held on the effective date of the transaction (and if the
holders are offered a choice of consideration, the type of consideration chosen
by the holders of a majority of the outstanding Shares). If such consideration
received in the merger is not solely common stock of the successor corporation
or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of
the Option or Stock Purchase Right, for each Share of Optioned Stock subject to
the Option or Stock Purchase Right, to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger.

         13.      Time of Granting Options and Stock Purchase Rights. The date
of grant of an Option or Stock Purchase Right shall, for all purposes, be the
date on which the Administrator makes the determination granting such Option or
Stock Purchase Right, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option or Stock Purchase Right is so granted within a reasonable time
after the date of such grant.

         14.      Amendment and Termination of the Plan.

                  (a)      Amendment and Termination. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law
or regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

                  (b)      Effect of Amendment or Termination. Any such
amendment or termination of the Plan shall not affect Options or Stock Purchase
Rights already granted, and such Options and Stock Purchase Rights shall remain
in full force and effect as if this Plan had not been amended or terminated,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

         15.      Conditions Upon Issuance of Shares. Shares shall not be
issued pursuant to the exercise of an Option or Stock Purchase Right unless the
exercise of such Option or Stock Purchase Right and the issuance and delivery
of such Shares pursuant thereto shall comply with all relevant provisions of
law, including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock


                                 Exhibit 4.3.8

exchange upon which the Shares may then be listed, and shall be further subject
to the approval of counsel for the Company with respect to such compliance.

                  As a condition to the exercise of an Option or Stock Purchase
Right, the Company may require the person exercising such Option or Stock
Purchase Right to represent and warrant at the time of any such exercise that
the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

         16.      Reservation of Shares. The Company, during the term of this
Plan, shall at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

                  The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares
hereunder, shall relieve the Company of any liability in respect of the failure
to issue or sell such Shares as to which such requisite authority shall not
have been obtained.

         17.      Agreements. Options and Stock Purchase Rights shall be
evidenced by written agreements in such form as the Administrator shall approve
from time to time.


         18.      Shareholder Approval. Continuance of the Plan shall be
subject to approval by the shareholders of the Company within twelve (12)
months before or after the date the Plan is adopted. Such shareholder approval
shall be obtained in the degree and manner required under Applicable Laws and
the rules of any stock exchange upon which the Common Stock is listed.

         19.      Information to Optionees and Purchasers. The Company shall
provide to each Optionee and to each individual who acquires Shares pursuant to
the Plan, not less frequently than annually during the period such Optionee or
purchaser has one or more Options or Stock Purchase Rights outstanding, and, in
the case of an individual who acquires Shares pursuant to the Plan, during the
period such individual owns such Shares, copies of annual financial statements.
The Company shall not be required to provide such statements to key employees
whose duties in connection with the Company assure their access to equivalent
information.
