time during the term of her employment in conflict with the best interest of
Company.

             2.3 During the term of this Agreement, Executive will not directly

             4.3 Executive shall be eligible to participate in and be covered by
any pension, insurance, reimbursement, supplemental disability, and other plans
maintained by the Company from time to time.

             4.4 The Company shall pay on Executive's behalf or reimburse
Executive for reasonable expenses incurred in connection with her employment
including any business travel, dues, cost of attending industry conventions,
meetings, and entertainment expenses for entertainment aiding the development of
the Company. Executive agrees to submit receipts and other documentation to
support the above expenses as a condition of reimbursement therefore.

             4.5 If this Agreement is terminated other than by the death of
Executive, Executive shall have the right to assume the key-person insurance
policy that the Company has in place, if any.

         5. TERMINATION.

             5.1 Executive may voluntarily terminate her employment upon giving
to Company not less than one hundred twenty (120) days written notice of
Executive's intention to do so.

             5.2 This Agreement shall terminate upon the earlier of date of
death, the date when Executive becomes "completely disabled" as that term is
defined in Section 6 below, the expiration of the Term of Employment, or as
otherwise permitted by law. In the event of death or disability, the Company
shall continue Executive's salary for six (6) months from the date of death or
complete disability. In the event of complete disability, the amount of salary
continuation shall be reduced by the amount of any disability payments made to
Executive under the Company's insurance policy. In addition, any stock options
granted to Executive prior to death or complete disability which would normally
vest during the twelve (12) months following such death or disability shall vest
and may be exercised in accordance with the term of the options.

<PAGE>

             5.3 The Company may terminate this Agreement for cause during the
Term of Employment by written notice given to Executive, effective immediately
or any later date specified by Company, in any of the following events:

             (a) conviction in a court of competent jurisdiction regarding any
violation of law or regulation by Executive which affects adversely the ability
of Executive to perform her duties, obligations and responsibilities herein or
the good name, goodwill or reputation of Company,

             (b) the failure of Executive to carry out the reasonable directions
of Company's Board of Directors, or

             (c) for any reason specified in California Labor Code Section 2924,
a copy of which is attached hereto as Exhibit "C".

             There shall be no severance pay in the event of termination for
cause.

         6. DEATH OF DISABILITY DURING TERM OF EMPLOYMENT. The term "completely
disabled" as used herein shall mean the inability of the Executive to perform
her duties hereunder for the reason that she has become permanently disabled
within the meaning of any policy of disability income insurance covering
Executives of the Company then in force. In the event the Company has no policy
of disability income insurance covering the executives of the Company in force
when Executive becomes disabled, the term "completely disabled" shall mean the
inability of Executive to perform her duties hereunder by reason of any
incapacity, physical or mental, which the Board of Directors of the Company,
based upon medical advice or opinion provided by a licensed physician acceptable
to said Board of Directors of the Company, determines to have incapacitated
Executive from satisfactorily performing all of her usual services for the
Company during the foreseeable future, taking into account the essential
functions of Executive's position and the existence of reasonable accommodation,
if any, to permit Executive to perform these duties. The action of said Board of
Directors shall be final and binding and the date such action is taken shall be
the date of such complete disability for purposes of termination of this
Agreement.

relating to the Company's business, which are or have been in Executive's

                PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT

In consideration of the execution of an Employment Agreement by Westbridge
Research Group (the "Company"), and the compensation now and hereafter paid to
me, I hereby agree as follows:

1. RECOGNITION OF COMPANY'S RIGHTS; NONDISCLOSURE. At all times during the term
of my employment and thereafter, I will hold in strict confidence and will not
disclose, use, lecture upon or publish any of the Company's Proprietary
Information (defined below) except as such disclosure, use or publication may be
required in connection with my work for the Company or unless an appropriate
officer of the Company expressly authorizes such in writing. I hereby assign to
the Company any rights I may have or acquire in such Proprietary Information and
recognize that all Proprietary Information shall be the sole property of the
Company and its assigns, and the Company and its assigns shall be the sole owner
of all trade secrets rights, patent rights, copyrights, mask work rights and all
other rights through out the world (collectively, "Proprietary Rights") in
connection therewith.

2. "PROPRIETARY INFORMATION". As herein stated "Proprietary Information" shall
mean trade secrets, confidential knowledge, data or any other proprietary
information of the Company. By way if illustration but not limitation,
"Proprietary Information" includes (a) trade secrets, inventions, ideas,
processes, formulas, data, programs, other works of authorship, know-how,
improvements, discoveries, developments, designs and techniques (hereinafter
collectively referred to as "Inventions") and (b) information regarding plans
for research, development, new products, marketing and selling, business plans,
budgets and unpublished financial statements, licenses, processes and costs,
suppliers and customers.

3. THIRD PARTY INFORMATION. I understand, in addition, that the Company has
received and in the future will receive from third parties confidential or
proprietary information ("Third Party Information") subject to a duty on the
Company's part to maintain the confidentiality of such information and to use it
only for certain limited purposes. During the term of my employment and
thereafter I will hold Third Party Information in the strictest confidence and
will not disclose (to anyone other than Company personnel who need to know such
information in connection with their work for the Company) or use, except in
connection with my work for the Company, Third Party Information unless
expressly authorized by an officer of the Company in writing.

4. ASSIGNMENT OF INVENTIONS. I hereby confirm my assignment to the Company all
my rights, title and interest in and to all Inventions (and all Proprietary
Rights with respect thereto) whether or not patentable or registerable under
copyright or similar statutes, made or conceived or reduced to practice or
learned by me, either alone or jointly with others, during the period of my
employment with the Company. Inventions assigned to or as directed by the
Company by this paragraph 4 are hereinafter referred to as "Company Inventions".
I recognize that this Agreement does not require assignment of any invention
which qualifies fully for protection under Section 2870 of the California Labor
Code (hereinafter "Section 2870") which provides as follows:

<PAGE>

         "i. Any provision in an employment agreement which provides that an
         Executive shall assign or offer to assign, any of her or her rights in
         an invention to his or her employer shall not apply to an invention
         that the Executive developed entirely on his or her own time without
         using the employer's equipment, supplies, facilities or trade secret
         information except for those inventions that either:

                  (1) Relate at the time of conception or reduction to practice
                  to the invention to the employer's business, or actual or
                  demonstrably anticipated research or development of the
                  employer.

                  (2) Result from any work performed by the Executive for the
                  employer.

         ii. To the extent a provision in an employment agreement purports to
         require an Executive to assign an invention otherwise excluded form
         being required to be assigned under subdivision (i), the provision is
         against the public policy of this state and is unenforceable."

5. GOVERNMENT. I also agree to assign all my right, title and interest in and to
any and all Inventions, required to be transferred to the United States required
by a contract between the Company and the United States or any of its agencies.

6. WORKS FOR HIRE. I acknowledge that all original works of authorship which are
made by me (solely or jointly with others) in the scope of my employment and
which are protectable by copyright are "works made for hire," as that term is
defined in the United States Copyrights Act (17 U.S.C., Section 101).

7. ENFORCEMENT OF PROPRIETARY RIGHTS. I will assist the Company in every proper
way to obtain and from time to time enforce United States and foreign
Proprietary Rights relating to Company Inventions in any and all countries. To
the end I will execute, verify and deliver such documents and perform such other
acts (including appearances as a witness) as the Company may reasonably request
for use in applying for, obtaining, perfecting, evidencing, sustaining and
enforcing such Proprietary Rights to the Company or its designee. In addition, I
will execute, verify and deliver assignments of such Proprietary Rights to the
Company or its designees. My obligation to assist the Company with respect to
Proprietary Rights relating to such Company Inventions in any and all countries
shall continue beyond the termination of my employment, and the Company shall
compensate me at a reasonable rate after my termination for the time actually
spent by me at the Company's request on such assistance.

<PAGE>

8. NO CONFLICTING OBLIGATION. I represent that my performance of all the terms
of this Agreement and an Executive Employment Agreement does not and will not
breach any agreement to keep in confidence information acquired by me in
confidence or in trust prior to my employment by the Company. I have not entered
into, and agree I will not enter into, an agreement either written or oral in
conflict herewith.

9. RETURN OF COMPANY DOCUMENTS. When I leave the employ of the Company, I will
deliver to the Company any and all drawings, notes, memoranda, specifications,
devices, formulas and documents, together with all copies thereof, and other
material containing or disclosing any Company Inventions, Third Party
Information or Proprietary Information of the Company. I further agree that any
property situated on the Company's premises and owned by the Company, including
disks and other storage media, filing cabinets or other work areas, is subject
to inspection by Company personnel at any time with or without notice. Prior to
leaving, I will cooperate with the Company in completing and signing the
Company's termination statement for technical and management personnel.

10. LEGAL AND EQUITABLE REMEDIES. Because my services are personal and unique
and because I may have access to and become acquainted with the Proprietary
Information of the Company, the Company shall have the rights to enforce this
Agreement and any of its provisions by injunction, specific performance or other
equitable relief, without bond and without prejudice to any other rights and
remedies that the Company may have for a breach of this Agreement.

11. NOTICES. All notices, requests, consents and other communications required
or permitted to be given hereunder shall be in writing, and deemed to have been
duly given when delivered by the U.S. Postal Service, postage prepaid,

representations, interpretations, omissions or other material facts including
but not limited or any assumed bailiffs of the Parties hereto.

unenforceable by law, then such provision will be deemed stricken from the

         4. OPTIONAL CONVERSION PROVISIONS.

                  a. The Holder shall have the right, at its option, and upon
written notice of conversion, in the form attached as EXHIBIT A hereto, to
convert all, but not part, of the entire unpaid principal amount of the
obligation underlying this Note, plus all accrued interest thereon, at any time
after the date of this Note, and (subject to the satisfaction of the conditions
hereinafter described) prior to the repayment in full of the principal amount of
this Note (the "CONVERSION PERIOD"), subject to the terms and provisions of this
Note, into shares ("CONVERSION SHARES") of common stock of the Company, par
value $0.01 per share (the "COMMON STOCK"), calculated as to each conversion to
the greatest number of full shares of Common Stock, disregarding fractions, with
a cash adjustment for fractional shares as hereinafter provided, at a per share
conversion price equal to $0.48 per share (the "CONVERSION PRICE"); PROVIDED,
HOWEVER, that such right of conversion shall only be exercisable at such time as
the exercise of such

                                       2
<PAGE>

right of conversion and the delivery of such shares of Common Stock are lawful
under federal securities laws and the securities laws of the jurisdiction of
residence of all persons to whom such shares of Common Stock are otherwise
deliverable. Notwithstanding anything to the contrary herein, the Company shall
not be obligated to deliver any certificates for any shares of Common Stock into
which this Note shall have been exercised until the delivery by the Holder to
the Company of the original of this Note. In the event the Holder shall give
notice to the Company of the Holder's exercise of such right of conversion, the
Holder shall not be entitled to withdraw the exercise of such right of
conversion without the written consent of the Company. Noteholders who do not
advise the Company of their intention to convert the Note in accordance with the
provisions hereof on or before the end of the Conversion Period shall not be
entitled to convert their Notes hereunder.

                  b. Upon such delivery of notice and surrender of this Note, as
aforesaid, the Company shall cause to be issued and to be mailed to the Holder,
as soon as practicable after the receipt by the Company of such notice and
surrender of this Note by the Holder to the Company, a certificate or
certificates for the number of full shares of Common Stock into which this Note
has been so converted upon the exercise of such conversion rights, together with
cash, as provided hereinbelow, in respect of any fractional shares of Common
Stock otherwise issuable upon such delivery and surrender. Such certificate or
certificates shall be deemed to have been issued and the Holder shall be deemed
to have become a holder of record of such shares of Common Stock as of the date
of receipt by the Company of such notice and surrender; PROVIDED, HOWEVER, that
if, at the date of such notice and surrender, the transfer books for the Common
Stock or other class of stock purchasable upon the exercise of such conversion
rights shall be closed, the certificate or certificates for the shares of Common
Stock in respect of which such conversion rights are then exercised shall be
issuable as of the date on which such books shall next be opened, and until such
date the Company shall be under no duty to deliver any certificate for such
shares of Common Stock; and PROVIDED, FURTHER, that the transfer books of
record, unless otherwise required by law, shall not be closed at any one time
for a period longer than twenty (20) days. The rights of purchase represented by
the foregoing conversion rights shall be exercisable, at the election of the
Holder, either in full or from time to time in part.

         5. NO FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the conversion rights set
forth hereinabove. With respect to any fraction of a share called for upon the
exercise of any such conversion rights hereunder or the automatic conversion of
this Note, the Company shall issue to the Holder one whole share of Common Stock
in lieu of such fractional share.

         6. ADJUSTMENTS TO CONVERSION PRICE. The number of shares of Common
Stock issuable upon conversion of this Note shall be subject to adjustment, in
case the Company shall: (a) pay a dividend on the Common Stock in shares of
Common Stock or make a distribution in shares of Common Stock; (b) subdivide its
outstanding shares of Common Stock; (c) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock; or (d) issue by
reclassification of its shares of stock other securities of the Company. The

                                       3
<PAGE>

number of shares of Common Stock purchasable upon conversion of this Note
immediately prior thereto shall be adjusted so that the holder of this Note
shall be entitled to receive the kind and number of shares of Common Stock or
other securities of the Company which he would have owned or have been entitled
to receive after the happening of any of the events described above, had this
Note been converted immediately prior to the happening of such event or as of
any record date with respect thereto. An adjustment made pursuant to this
paragraph shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event.

         7. PREPAYMENT OF NOTE. This Note shall have the following redemption
provisions:

                  a. This Note may be prepaid, at the election of the Company,
as a whole, or from time to time in part, at the price equal to the outstanding
principal of the Note and accrued interest thereon to the prepayment date, at
any time.

                  b. In case the Company shall desire to exercise the right to
prepay all or any part of the Note in accordance with its terms, it shall fix a
date for prepayment and shall mail a notice of such prepayment at least ten (10)
days prior to the date fixed for prepayment to the Holder of the Note to be
redeemed as a whole or in part at his address as the same appears on the
registry books of the Company. If mailed in the manner herein provided, the
notice shall be conclusively presumed to have been duly given, whether or not
any such Holder receives such notice. Any defect in the notice to the Holder of
any Note designated for prepayment as a whole or in part shall not affect the
validity of the proceedings for the prepayment of the Note.

         Each such notice of prepayment shall specify the date fixed for
prepayment, the prepayment price, the place where the Note is to be surrendered
for prepayment, which shall be the office of the Company, that payment will be
made upon presentation and surrender of the Note, that accrued interest to the
redemption date will be paid as specified in said notice, and that on and after
said date, interest thereon or on the portions thereof to be redeemed will cease
to accrue. If less than all the outstanding amount of the Note is to be prepaid,
the notice of prepayment shall specify the amount of the Note to be redeemed. In
case the Note is to be redeemed in part only, the notice of prepayment shall
state the portion of the principal amount thereof to be prepaid and shall state
that on and after the date fixed for prepayment, upon surrender of the Note, a
new Note in the principal amount and Maturity Date equal to the unredeemed
portion thereof will be issued.

                  c. If notice of prepayment has been mailed as above provided,
the Note or portion of the Note with respect to which such notice has been
mailed shall become due and payable on the date and at the place or places
stated in such notice, at the applicable prepayment price, together with accrued
interest to the prepayment date, and on and after said date (unless the Company
shall default in the payment of the Note at the applicable prepayment price,
together with accrued interest to said date) any interest on the Note or

                                       4
<PAGE>

portions of the Note so called for prepayment shall cease to accrue, and the
Notes and portion of the Note shall be deemed not to be outstanding hereunder
and shall not be entitled to any benefit under this Note except to receive
payment of the prepayment price, together with accrued interest to the date
fixed for prepayment. On presentation and surrender of the Note at the office of
the Company, the Note or the specified portions thereof shall be paid and
prepaid by the Company at the applicable prepayment price, together with accrued
interest, to the date fixed for prepayment.

         Upon presentation of the Note to be prepaid in part only, the Company
shall execute and deliver to the Holder, at the expense of the Company, a new
Note, of authorized denominations in aggregate principal amount and Maturity
Date equal to the unpaid portion of the Note so presented.

                  d. Notwithstanding anything to the contrary, in the event that
the Company shall deliver a notice of prepayment, the Holder shall have the
option, prior to the Company's payment of the prepayment price, but in no event
less than fifteen (15) days of the delivery of a prepayment notice by the
Company to the Holder, to convert this Note in accordance with the Optional
Conversion provisions of Section 4 of this Note.

         8. CONSOLIDATIONS AND MERGERS. In case of any consolidation of the
Company with or merger of the Company into another corporation or in case of any
sale or conveyance to another corporation of the property of the Company as an
entirety or substantially as an entirety, the Company or such successor or
purchasing corporation, as the case may be, shall execute an agreement that any
holder of this Note shall have the right thereafter, upon payment of the
Conversion Price, as the case may be, in effect immediately prior to such
action, to purchase upon conversion of this Note the kind and amount of shares
and other securities and property which he would have owned or have been
entitled to receive after the happening or such consolidation, merger, sale or
conveyance had this Note been converted immediately prior to such action. The
Company shall mail by first class mail, postage prepaid, to each holder of this
Note, notice of the execution of any such agreement. Such agreement shall
provide for adjustments, which shall be as nearly equivalent as may be
practicable to the adjustments provided for herein. The provisions of this
paragraph shall similarly apply to successive consolidations, mergers, sales or
conveyances.

         9. RESERVATION OF SHARES. There has been reserved, and the Company
shall at all times keep reserved so long as this Note remains outstanding, out
of its authorized shares of Common Stock a number of shares of Common Stock
sufficient to provide for the exercise of the rights of purchase represented by
the foregoing conversion rights. The transfer agent for any shares of the
Company's capital stock issuable upon the exercise of any of the rights of
purchase aforesaid will be irrevocably authorized and directed at all times to
reserve such number of authorized shares of Common Stock as shall be requisite
for such purpose. The Company will keep a copy of this Note on file with the
transfer agent for the Common Stock and with every subsequent transfer agent for
any shares of the Company's capital stock issuable upon the exercise of the
rights of purchase represented by the foregoing conversion rights. The Company
will supply the transfer agent with duly executed stock certificates for issue
against exercise of the foregoing conversion rights and will provide or
otherwise make available any cash which may be payable in lieu of fractional
shares as provided hereinabove. Promptly after the date of the expiration of the
foregoing conversion rights, the Company shall certify to the transfer agent the
aggregate number of shares of Common Stock previously subject to such conversion
rights, and thereafter no shares shall be subject to reservation in respect of
such conversion rights.

                                       5
<PAGE>

         10. TAXES. The Holder shall pay all taxes and charges that may be
imposed by the United States of America or any state or territory thereof
("TAXES") attributable to the initial issuance of Conversion Shares in
connection with the automatic conversion of this Note, or which may be payable
in respect of any transfer involved in the issuance of any Notes or Conversion
Shares in a name other than that of the Noteholder of record surrendered upon
the conversion of this Note, and the Company shall not be required to issue or
deliver such Conversion Shares unless or until the person or persons requesting
the issuance thereof shall have paid to the Company the amount of such Taxes or
shall have established to the satisfaction of the Company that such Taxes have
been paid.

         11. CERTAIN RESTRICTIONS ON TRANSFERABILITY.

                  a. This Note and the conversion rights set forth hereinabove
may not be sold, pledged, hypothecated, assigned, encumbered, gifted or
otherwise transferred or alienated in any manner by the Holder without delivery
of prior written notice thereof to the Board of Directors of the Company and
compliance with the provisions of this Note, and, unless such notice shall have
been so delivered and the terms of this Note shall have been so complied with,
shall not run to any assignee of the Note.

                  b. This Note has not been registered under the Securities Act
or applicable state securities laws and may not be sold, pledged or otherwise

to such effect has been rendered by counsel. The Company is under no obligation
to register the Note or to comply with any applicable exemption from
registration. Subject to the above and the receipt of the consent of the Company
to any such transfer, the transfer of this Note may be registered by the
registered holder hereof in person or by duly authorized attorney, at the office
of the Company at the address set forth in this Note, by delivering this Note
for cancellation accompanied by delivery to the Company of a duly executed
instrument of transfer, and thereupon the Company shall execute, in the name of
the transferee or transferees, a new Note of like form for the same aggregate
principal amount.

                  c. With respect to the issue of shares of Common Stock upon
conversion of this Note and the transfer of such shares of Common Stock:

                           (i) The Holder and any transferee of the shares of
         Common Stock issuable upon the exercise of the foregoing conversion
         rights agree that, notwithstanding anything in this Note to the
         contrary, during such period as delivery of a prospectus or like
         document with respect to such Common Stock may be required by the

                                       6
<PAGE>

         securities laws of any applicable jurisdiction, no public distribution
         of such Common Stock will be made in a manner or on terms different
         from those set forth in, or without delivery of, a prospectus or other
         document then meeting the requirements of such laws. The Holder and any
         such transferee further agree that if any distribution of any of such
         Common Stock is proposed to be made to them or by them otherwise than
         by delivery of such a prospectus or other document meeting the
         requirements of the securities laws of all applicable jurisdictions,
         such action shall be taken only after submission to the Company of an
         opinion of counsel, reasonably satisfactory in form and substance to
         the Company's counsel, to the effect that the proposed distribution
         will not be in violation of such securities laws.

                           (ii) It shall be a condition to the transfer of such
         Common Stock that any transferee of such Common Stock deliver to the
         Company his or its written agreement to accept and be bound by all of
         the terms and conditions of this Note.

         12. NO STOCKHOLDER STATUS. The Holder shall not, by virtue hereof, be
entitled to any of the rights of a stockholder in the Company, either at law or
in equity; PROVIDED, HOWEVER, that in the event any certificate or certificates
representing shares of Common Stock are issued to the Holder upon exercise of
the foregoing conversion rights, then the Holder shall, for all purposes, be
deemed to have become the holder of record of such shares of Common Stock on the
date as of which such certificate or certificates were deemed issued as provided
hereinabove, irrespective of the date of delivery of such share certificate or
certificates. The rights of the Holder under this Note are limited to those
expressed herein, and the Holder, by its acceptance hereof, consents to and
agrees to be bound by and to comply with all of the provisions of this Note,
including, without limitation, all of the obligations imposed upon the Holder by
the preceding paragraph hereof.
