Paul D. Levy

This Option shall vest and may be exercised (in accordance with
Section 3), in whole or in part, in accordance with the following
schedule:
1/48th of the Shares (439,814.8125 Shares) subject to the Option
shall vest each month after the Vesting Commencement Date, so that the
Option shall be fully vested four (4) years from the Date of Grant,
subject to the Optionee continuing to be a Service Provider on such
dates.
All of the remaining Shares subject to the Option shall vest
immediately prior to the closing of a change of control.  A "change of
control" shall mean a merger or consolidation of the Company with or
into another corporation, entity or person (where the stockholders of
the Company immediately prior to such merger or consolidation hold less

following the merger or consolidation), or the sale of all or
substantially all of the Company's assets to another corporation,
entity or person.  In addition, all of the remaining Shares subject to
the Option shall vest if Optionee is not elected as a member of the
Company's Board of Directors, is removed (other than for cause) from
the Board of Directors or is not reelected to the Board of Directors,
unless, in either event, Optionee has voluntarily resigned as an
employee of the Company; provided, however that a voluntary resignation
from the Board of Directors by Optionee or Optionee's voluntary
election to not stand for election to the Board of Directors shall not
cause the remaining Shares subject to the Option to vest.
Termination Period
This Option may be exercised, to the extent it is then vested,
within three (3) months after Optionee ceases to be a Service Provider
in accordance with Section 8 of this Agreement.  Upon the death or
Disability of the Optionee, this Option may be exercised, to the extent
it is then vested, within twelve (12) months after the Optionee ceases
to be a Service Provider in accordance with Sections 9 and 10 of this
Agreement.  In no event shall this Option be exercised later than the
Term/Expiration Date provided.

(i) Subject to subsections 3(a)(ii) and 3(a)(iii)
below, this Option shall be exercisable cumulatively according to the
Vesting Schedule set forth in the Notice of Grant.  Alternatively, at
the election of the Optionee, this Option may be exercised in whole or
in part at any time as to Shares that have not yet vested.  For
purposes of this Agreement, Shares subject to the Option shall vest
based on continued employment of Optionee continuing to be a Service
Provider with the Company.  Vested Shares shall not be subject to the
Company's repurchase right (as set forth in the Restricted Stock
Purchase Agreement, attached hereto as Exhibit C-1).
(ii) As a condition to exercising this Option for
unvested Shares, the Optionee shall execute the Restricted Stock
Purchase Agreement.
(iii) This Option may not be exercised for a fraction
of a Share.
(b) Method of Exercise.  This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the
"Exercise Notice"), which shall state the election to exercise the
Option, the number of Shares in respect of which the Option is being
exercised (the "Exercised Shares"), and such other representations and
agreements as may be required by the Company.  The Exercise Notice
shall be completed by the Optionee and delivered to Secretary of the
Company.  The Exercise Notice shall be accompanied by payment of the
aggregate Exercise Price as to all Exercised Shares.  This Option shall
be deemed to be exercised upon receipt by the Company of such fully
executed Exercise Notice accompanied by such aggregate Exercise Price.
(c) Legal Compliance.  No Shares shall be issued pursuant
to the exercise of this Option unless such issuance and exercise
complies with Applicable Laws.  Assuming such compliance, for income
tax purposes the Exercised Shares shall be considered transferred to
the Optionee on the date the Option is exercised with respect to such
Exercised Shares.
(d) Buyout Provisions.  The Board 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 Board shall establish and
communicate to the Optionee at the time that such offer is made.
4. Optionee's Representations.  In the event the Shares have
not been registered under the Securities Act of 1933, as amended, at
the time this Option is exercised, the Optionee shall, if required by
the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B.
5. Method of Payment.  Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the
election of the Optionee:
(a) cash or check;
(b) consideration received by the Company under a
cashless exercise program implemented by the Company; or
(c) surrender of other Shares which (i) in the case of
Shares acquired upon exercise of an option, have been owned by the
Optionee for more than six (6) months on the date of surrender, and
(ii) have a Fair Market Value on the date of surrender equal to the
aggregate Exercise Price of the Exercised Shares.
(d) delivery of Optionee's promissory note (the "Note")
in the form attached hereto as Exhibit E, in the amount of the
aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement
attached hereto as Exhibit D.  The Note shall bear interest at the
"applicable federal rate" prescribed under the Code and its regulations
at time of purchase, and shall be secured by a pledge of the Shares
purchased by the Note pursuant to the Security Agreement.
6. Non-Transferability of Option.  This Option may not be
transferred in any manner otherwise than by will or by the laws of
descent or distribution and may be exercised during the lifetime of
Optionee only by the Optionee.  The terms of this Agreement shall be
binding upon the executors, administrators, heirs, successors and
assigns of the Optionee.
7. Term of Option.  This Option may be exercised only within
the term set out in the Notice of Grant, and may be exercised during
such term only in accordance with the terms of this Agreement.
8. Termination of Relationship as a Service Provider.  If the
Optionee ceases to be a Service Provider (other than for death or
Disability), this Option may be exercised for a period of three (3)
months after the date of such termination (but in no event later than
the expiration date of this Option as set forth in the Notice of Grant)
to the extent that the Option is vested on the date of such
termination.  To the extent that the Optionee does not exercise this
Option within the time specified herein, the Option shall terminate.
9. Disability of Optionee.  If the Optionee ceases to be a
Service Provider as a result of the Optionee's Disability, this Option
may be exercised for a period of twelve (12) months after the date of
such termination (but in no event later than the expiration date of
this Option as set forth in the Notice of Grant) to the extent that the
Option is vested on the date of such termination.  To the extent that
Optionee does not exercise this Option within the time specified
herein, the Option shall terminate.
10. Death of Optionee.  If the Optionee dies while a Service
Provider, 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 date of this 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
Option is vested on the date of death.  If, after death, the Optionee's
estate or a person who acquired the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time
specified herein, the Option shall terminate.
11. Adjustments Upon Changes in Capitalization, Dissolution,
Merger or Asset Sale.
(a) Changes in Capitalization.  Subject to any required
action by the stockholders of the Company, the number of shares of
Common Stock covered by this Option, as well as the price per share of
Common Stock covered by this Option, shall be proportionately adjusted
for any increase or decrease in the number of issued shares of Common
Stock 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;
provided, however, that 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 this Option.
(b) Dissolution or Liquidation.  In the event of the
proposed dissolution or liquidation of the Company, the Board shall
notify Optionee as soon as practicable prior to the effective date of
such proposed transaction.  The Board in its discretion may provide for
the Optionee to have the right to exercise his or her Option until
fifteen (15) days prior to such transaction as to all of the Optioned
Stock covered thereby, including Shares as to which the Option would
not otherwise be exercisable. The Board may permit the Option to be
exercised contingent upon this transaction. To the extent it has not
been previously exercised, the Option will terminate immediately prior
to the consummation of such proposed action.
12. Lock-Up Period.  Optionee agrees, in connection with the
Company's initial public offering of the Company's securities, (i) not
to sell, make short sales of, loan, grant any options for the purchase
of, or otherwise dispose of any shares of Common Stock of the Company
held by Optionee (other than those shares included in the registration)
without the prior written consent of the Company or the underwriters
managing such initial underwritten public offering of the Company's
securities for up to one hundred eighty (180) days from the effective
date of such registration and (ii) further agrees to execute any
agreement reflecting (i) above as may be requested by the underwriters
at the time of the public offering.
13. Notices.  Any notice to be given to the Company hereunder
shall be in writing and shall be addressed to the Company at its then
current principal executive office or to such other address as the
Company may hereafter designate to the Optionee by notice as provided
in this Section.  Any notice to be given to the Optionee hereunder
shall be addressed to the Optionee at the address set forth beneath his
signature hereto, or at such other address as the Optionee may
hereafter designate to the Company by notice as provided herein.  A
notice shall be deemed to have been duly given when personally
delivered or mailed by registered or certified mail to the party
entitled to receive it.
14. Tax Consequences.  Some of the federal tax consequences
relating to this Option, as of the date of this Option, are set forth
below.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND
REGULATIONS ARE SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.
(a) Exercising the Option.  The Optionee may incur
regular federal income tax liability upon exercise of a Nonstatutory
Stock Option (an "NSO").  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates)
equal to the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price.  If
the Optionee is an Employee or a former Employee, the Company will be
required to withhold from his or her compensation or collect from
Optionee and pay to the applicable taxing authorities an amount in cash
equal to a percentage of this compensation income at the time of
exercise, and may refuse to honor the exercise and refuse to deliver
Shares if such withholding amounts are not delivered at the time of
exercise.
(b) Disposition of Shares.  If the Optionee holds NSO
Shares for at least one year, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.
(c) Section 83(b) Election for Unvested Shares Purchased
Pursuant to Options.  With respect to the exercise of this Option for
unvested Shares, an election may be filed by the Optionee with the
Internal Revenue Service, within 30 days of the purchase of the Shares,
electing pursuant to Section 83(b) of the Code to be taxed currently on
any difference between the purchase price of the Shares and their Fair
Market Value on the date of purchase.  This will result in a
recognition of taxable income to the Optionee on the date of exercise,
measured by the excess, if any, of the Fair Market Value of the Shares,
at the time the Option is exercised over the purchase price for the
Shares.  Absent such an election, taxable income will be measured and
recognized by Optionee at the time or times on which the Company's
repurchase option lapses.  Optionee is strongly encouraged to seek the
advice of his or her own tax consultants in connection with the
purchase of the Shares and the advisability of filing of the Election
under Section 83(b) of the Code.  A form of Election under
Section 83(b) is attached hereto as Exhibit C-5 for reference.
15. Entire Agreement; Governing Law.  This Agreement
constitutes the entire agreement of the parties with respect to the
subject matter hereof and supersedes in its entirety all prior
undertakings and agreements of the Company and Optionee with respect to
the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company
and Optionee.  This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California
16. NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES
AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE
HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL
OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED
AN OPTION OR PURCHASING SHARES HEREUNDER).  OPTIONEE FURTHER
ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND
SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME,
WITH OR WITHOUT CAUSE.
By your signature and the signature of the Company's
representative below, you and the Company agree that this Option is
granted under and governed by the terms and conditions of this
Agreement.  Optionee has reviewed this Agreement in its entirety, has
had an opportunity to obtain the advice of counsel prior to executing
this Agreement and fully understands all provisions of this Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all
decisions or interpretations of the Board upon any questions relating
to this Agreement.  Optionee further agrees to notify the Company upon
any change in the residence address indicated below.

INVESTMENT REPRESENTATION STATEMENT

OPTIONEE:       Paul D. Levy
COMPANY:        CATAPULSE INC.
SECURITY:       COMMON STOCK
AMOUNT: 21,111,111 Shares
DATE:           December 6, 1999

In connection with the purchase of the above-listed Securities,
the undersigned Optionee represents to the Company the following:
(a) Optionee is aware of the Company's business affairs
and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire
the Securities.  Optionee is acquiring these Securities for investment
for Optionee's own account only and not with a view to, or for resale
in connection with, any "distribution" thereof within the meaning of
the Securities Act of 1933, as amended (the "Securities Act").
(b) Optionee acknowledges and understands that the
Securities constitute "restricted securities" under the Securities Act
and have not been registered under the Securities Act in reliance upon
a specific exemption therefrom, which exemption depends upon, among
other things, the bona fide nature of Optionee's investment intent as
expressed herein.  In this connection, Optionee understands that, in
the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Optionee's representation was
predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a
deferred sale, for or until an increase or decrease in the market price
of the Securities, or for a period of one year or any other fixed
period in the future.  Optionee further understands that the Securities
must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available.
Optionee further acknowledges and understands that the Company is under
no obligation to register the Securities.  Optionee understands that
the certificate evidencing the Securities will be imprinted with a
legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of
counsel satisfactory to the Company, and any other legend required
under applicable state securities laws.
(c) Optionee is familiar with the provisions of Rule 701
and Rule 144, each promulgated under the Securities Act, which, in
substance, permit limited public resale of "restricted securities"
acquired, directly or indirectly from the issuer thereof, in a non-
public offering subject to the satisfaction of certain conditions.
Rule 701 provides that if the issuer qualifies under Rule 701 at the
time of the grant of the Option to the Optionee, the exercise will be
exempt from registration under the Securities Act.  In the event the
Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, ninety (90) days
thereafter (or such longer period as any market stand-off agreement may
require) the Securities exempt under Rule 701 may be resold, subject to
the satisfaction of certain of the conditions specified by Rule 144,
including:  (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a
market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of
certain public information about the Company, (3) the amount of
Securities being sold during any three month period not exceeding the
limitations specified in Rule 144(e), and (4) the timely filing of a
Form 144, if applicable.
                In the event that the Company does not qualify under
Rule 701 at the time of grant of the Option, then the Securities may be
resold in certain limited circumstances subject to the provisions of
Rule 144, which requires the resale to occur not less than one year
after the later of the date the Securities were sold by the Company or
the date the Securities were sold by an affiliate of the Company,
within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently
holds the Securities less than two years, the satisfaction of the
conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.
(d) Optionee further understands that in the event all of
the applicable requirements of Rule 701 or 144 are not satisfied,
registration under the Securities Act, compliance with Regulation A, or
some other registration exemption will be required; and that,
notwithstanding the fact that Rules 144 and 701 are not exclusive, the
Staff of the Securities and Exchange Commission has expressed its
opinion that persons proposing to sell private placement securities
other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in
establishing that an exemption from registration is available for such
offers or sales, and that such persons and their respective brokers who
participate in such transactions do so at their own risk.  Optionee
understands that no assurances can be given that any such other
registration exemption will be available in such event.

CATAPULSE INC.
RESTRICTED STOCK PURCHASE AGREEMENT
THIS AGREEMENT is made between Michael T. Devlin (the
"Purchaser") and CataPULSE Inc. (the "Company") as of December 6,
1999.
RECITALS
A.      Pursuant to the exercise of the stock option granted to
Purchaser under the Stand-Alone Stock Option Agreement (the "Option
Agreement") dated December 6, 1999 by and between the Company and
Purchaser, which such Option Agreement is hereby incorporated by
reference, Purchaser has elected to purchase 21,111,111 of those shares
which have not become vested under the vesting schedule set forth in
the Option Agreement ("Unvested Shares").  The Unvested Shares and the
shares subject to the Option Agreement which have become vested are
sometimes collectively referred to herein as the "Shares."
B.      As required by the Option Agreement, as a condition to
Purchaser's election to exercise the Option, Purchaser must execute
this Restricted Stock Purchase Agreement, which sets forth the rights
and obligations of the parties with respect to Shares acquired upon
exercise of the Option.
1. Repurchase Option.
(a) If Purchaser's status as a Service Provider is
terminated for any reason, including for cause, death, and disability,
the Company shall have the right and option to purchase from Purchaser,
or Purchaser's personal representative, as the case may be, all of the
Purchaser's Unvested Shares as of the date of such termination at the
price paid by the Purchaser for such Shares (the "Repurchase Option").
(b) Upon the occurrence of a termination, the Company may
exercise its Repurchase Option by delivering personally or by
registered mail, to Purchaser (or his transferee or legal
representative, as the case may be), within ninety (90) days of the
termination, a notice in writing indicating the Company's intention to
exercise the Repurchase Option and setting forth a date for closing not
later than thirty (30) days from the mailing of such notice. The
closing shall take place at the Company's office.  At the closing, the
holder of the certificates for the Unvested Shares being transferred
shall deliver the stock certificate or certificates evidencing the
Unvested Shares, and the Company shall deliver the purchase price
therefor.
(c) At its option, the Company may elect to make payment
for the Unvested Shares to a bank selected by the Company.  The Company
shall avail itself of this option by a notice in writing to Purchaser
stating the name and address of the bank, date of closing, and waiving
the closing at the Company's office.
(d) If the Company does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within
ninety (90) days following the termination, the Repurchase Option shall
terminate.
(e) The Repurchase Option shall terminate in accordance
with the Vesting Schedule in Optionee's Option Agreement.
2. Transferability of the Shares; Escrow.
(a) Purchaser hereby authorizes and directs the Secretary
of the Company, or such other person designated by the Company, to
transfer the Unvested Shares as to which the Repurchase Option has been
exercised from Purchaser to the Company.
(b) To insure the availability for delivery of
Purchaser's Unvested Shares upon repurchase by the Company pursuant to
the Repurchase Option under Section 1, Purchaser hereby appoints the
Secretary, or any other person designated by the Company as escrow
agent, as its attorney-in-fact to sell, assign and transfer unto the
Company, such Unvested Shares, if any, repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this
Agreement, deliver and deposit with the Secretary of the Company, or
such other person designated by the Company, the share certificates
representing the Unvested Shares, together with the stock assignment
duly endorsed in blank, attached hereto as Exhibit C-2.  The Unvested
Shares and stock assignment shall be held by the Secretary in escrow,
pursuant to the Joint Escrow Instructions of the Company and Purchaser
attached as Exhibit C-3 hereto, until the Company exercises its
purchase right as provided in Section 1, until such Unvested Shares are
vested, or until such time as this Agreement no longer is in effect.
As a further condition to the Company's obligations under this
Agreement, the spouse of the Purchaser, if any, shall execute and
deliver to the Company the Consent of Spouse attached hereto as Exhibit
C-4.  Upon vesting of the Unvested Shares, the escrow agent shall
promptly deliver to the Purchaser the certificate or certificates
representing such Shares in the escrow agent's possession belonging to
the Purchaser, and the escrow agent shall be discharged of all further
obligations hereunder; provided, however, that the escrow agent shall
nevertheless retain such certificate or certificates as escrow agent if
so required pursuant to other restrictions imposed pursuant to this
Agreement.
(c) The Company, or its designee, shall not be liable for
any act it may do or omit to do with respect to holding the Shares in
escrow and while acting in good faith and in the exercise of its
judgment.
(d) Transfer or sale of the Shares is subject to
restrictions on transfer imposed by any applicable state and federal
securities laws.  Any transferee shall hold such Shares subject to all
the provisions hereof and the Exercise Notice executed by the Purchaser
with respect to any Unvested Shares purchased by Purchaser and shall
acknowledge the same by signing a copy of this Agreement.
3. Ownership, Voting Rights, Duties.  This Agreement shall not
affect in any way the ownership, voting rights or other rights or
duties of Purchaser, except as specifically provided herein.
4. Legends.  The share certificate evidencing the Shares
issued hereunder shall be endorsed with the following legend (in
addition to any legend required under applicable state securities
laws):
THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE
AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE
STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY
OF THE COMPANY.
5. Adjustment for Stock Split.  All references to the number
of Shares and the purchase price of the Shares in this Agreement shall
be appropriately adjusted to reflect any stock split, stock dividend or
other change in the Shares which may be made by the Company after the
date of this Agreement.
6. Notices.  Notices required hereunder shall be given in
person or by registered mail to the address of Purchaser shown on the
records of the Company, and to the Company at their respective
principal executive offices.
7. Survival of Terms.  This Agreement shall apply to and bind
Purchaser and the Company and their respective permitted assignees and
transferees, heirs, legatees, executors, administrators and legal
successors.
8. Section 83(b) Election.  Purchaser hereby acknowledges that
he or she has been informed that, with respect to the exercise of an
option for Unvested Shares, an election may be filed by the Purchaser
with the Internal Revenue Service, within 30 days of the purchase of
the Shares, electing pursuant to Section 83(b) of the Code to be taxed
currently on any difference between the purchase price of the Shares
and their Fair Market Value on the date of purchase.  This will result
in a recognition of taxable income to the Purchaser on the date of
exercise, measured by the excess, if any, of the fair market value of
the Shares, at the time the option is exercised over the purchase price
for the Shares.  Absent such an election, taxable income will be
measured and recognized by Purchaser at the time or times on which the
Company's Repurchase Option lapses.  Purchaser is strongly encouraged
to seek the advice of his or her own tax consultants in connection with
the purchase of the Shares and the advisability of filing of the
Election under Section 83(b) of the Code.  A form of Election under
Section 83(b) is attached hereto as Exhibit C-5 for reference.
        PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER
SECTION 83(b), EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS
REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER'S BEHALF.
9. Representations.  Purchaser has reviewed with his own tax
advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement.
Purchaser is relying solely on such advisors and not on any statements
or representations of the Company or any of its agents.  Purchaser
understands that he or she (and not the Company) shall be responsible
for his or her own tax liability that may arise as a result of this
investment or the transactions contemplated by this Agreement.
10. Governing Law.  This Agreement shall be governed by the
internal substantive laws, but not the choice of law rules, of
California.
Purchaser represents that he or she has read this Agreement
and is familiar with its terms and provisions.  Purchaser hereby agrees
to accept as binding, conclusive and final all decisions or
interpretations of the Board upon any questions arising under this
Agreement.
IN WITNESS WHEREOF, this Agreement is deemed made as of the date
first set forth above.

SECURITY AGREEMENT
This Security Agreement is made as of December 6, 1999, between
CataPULSE Inc., a Delaware corporation ("Pledgee"), and Michael T.
Devlin ("Pledgor").
Recitals
Pursuant to Pledgor's election to purchase shares of Pledgee's
common stock ("Common Stock") under the Stand-Alone Stock Option
Agreement dated December 6, 1999 (the "Option"), between Pledgor and
Pledgee, and Pledgor's election under the terms of the Option to pay
for such shares with his promissory note (the "Note"), Pledgor has
purchased 21,111,111 shares of Pledgee's Common Stock (the "Shares") at
a price of $0.03 per share, for a total purchase price of $633,333.33.
The Note and the obligations thereunder are as set forth in Exhibit E
to the Option.
NOW, THEREFORE, it is agreed as follows:
1. Creation and Description of Security Interest.  In consid-
eration of the transfer of the Shares to Pledgor under the Option
Agreement, Pledgor, pursuant to the California Commercial Code, hereby
pledges all of such Shares (herein sometimes referred to as the
"Collateral") represented by certificate number ______, duly endorsed
in blank or with executed stock powers, and herewith delivers said
certificate to the Secretary of Pledgee ("Pledgeholder"), who shall
hold said certificate subject to the terms and conditions of this Secu-
rity Agreement.
The pledged stock (together with an executed blank stock assign-
ment for use in transferring all or a portion of the Shares to Pledgee
if, as and when required pursuant to this Security Agreement) shall be
held by the Pledgeholder as security for the repayment of the Note, and
any extensions or renewals thereof, to be executed by Pledgor pursuant
to the terms of the Option, and the Pledgeholder shall not encumber or
dispose of such Shares except in accordance with the provisions of this
Security Agreement.
2. Pledgor's Representations and Covenants.  To induce Pledgee
to enter into this Security Agreement, Pledgor represents and covenants
to Pledgee, its successors and assigns, as follows:
(a) Payment of Indebtedness.  Pledgor will pay the prin-
cipal sum of the Note secured hereby, together with interest thereon,
at the time and in the manner provided in the Note.
(b) Encumbrances.  The Shares are free of all other
encumbrances, defenses and liens, and Pledgor will not further encumber
the Shares without the prior written consent of Pledgee.
(c) Margin Regulations.  In the event that Pledgee's
Common Stock is now or later becomes margin-listed by the Federal
Reserve Board and Pledgee is classified as a "lender" within the
meaning of the regulations under Part 207 of Title 12 of the Code of
Federal Regulations ("Regulation G"), Pledgor agrees to cooperate with
Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such
regulations.
3. Voting Rights.  During the term of this pledge and so long
as all payments of principal and interest are made as they become due
under the terms of the Note, Pledgor shall have the right to vote all
of the Shares pledged hereunder.
4. Stock Adjustments.  In the event that during the term of
the pledge any stock dividend, reclassification, readjustment or other
changes are declared or made in the capital structure of Pledgee, all
new, substituted and additional shares or other securities issued by
reason of any such change shall be delivered to and held by the Pledgee
under the terms of this Security Agreement in the same manner as the
Shares originally pledged hereunder.  In the event of substitution of
such securities, Pledgor, Pledgee and Pledgeholder shall cooperate and
execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references
to "Shares" in this Security Agreement shall include the substituted
shares of capital stock of Pledgor as a result thereof.
5. Options and Rights.  In the event that, during the term of
this pledge, subscription Options or other rights or options shall be
issued in connection with the pledged Shares, such rights, Options and
options shall be the property of Pledgor and, if exercised by Pledgor,
all new stock or other securities so acquired by Pledgor as it relates
to the pledged Shares then held by Pledgeholder shall be immediately
delivered to Pledgeholder, to be held under the terms of this Security
Agreement in the same manner as the Shares pledged.
6. Default.  Pledgor shall be deemed to be in default of the
Note and of this Security Agreement in the event:
(a) Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or
(b) Pledgor fails to perform any of the covenants set
forth in the Option or contained in this Security Agreement for a
period of 10 days after written notice thereof from Pledgee.
In the case of an event of Default, as set forth above,
Pledgee shall have the right to accelerate payment of the Note upon
notice to Pledgor, and Pledgee shall thereafter be entitled to pursue
its remedies under the California Commercial Code.
7. Release of Collateral.  Subject to any applicable contrary
rules under Regulation G, there shall be released from this pledge a
portion of the pledged Shares held by Pledgeholder hereunder upon
payments of the principal of the Note.  The number of the pledged
Shares which shall be released shall be that number of full Shares
which bears the same proportion to the initial number of Shares pledged
hereunder as the payment of principal bears to the initial full
principal amount of the Note.
8. Withdrawal or Substitution of Collateral.  Pledgor shall
not sell, withdraw, pledge, substitute or otherwise dispose of all or
any part of the Collateral without the prior written consent of
Pledgee.
9. Term.  This pledge of Shares shall continue until the
payment of all indebtedness secured hereby, at which time the remaining
pledged stock shall be promptly delivered to Pledgor, subject to the
provisions for prior release of a portion of the Collateral as provided
in paragraph 7 above.
10. Insolvency.  Pledgor agrees that if a bankruptcy or insol-
vency proceeding is instituted by or against it, or if a receiver is
appointed for the property of Pledgor, or if Pledgor makes an
assignment for the benefit of creditors, the entire amount unpaid on
the Note shall become immediately due and payable, and Pledgee may
proceed as provided in the case of default.
11. Pledgeholder Liability.  In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of
his acts, or omissions to act, as Pledgeholder.
12. Invalidity of Particular Provisions.  Pledgor and Pledgee
agree that the enforceability or invalidity of any provision or
provisions of this Security Agreement shall not render any other
provision or provisions herein contained unenforceable or invalid.
13. Successors or Assigns.  Pledgor and Pledgee agree that all
of the terms of this Security Agreement shall be binding on their
respective successors and assigns, and that the term "Pledgor" and the
term "Pledgee" as used herein shall be deemed to include, for all
purposes, the respective designees, successors, assigns, heirs,
executors and administrators.
14. Governing Law.  This Security Agreement shall be
interpreted and governed under the internal substantive laws, but not
the choice of law rules, of California.

IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first above written.
