         SECTION 5. Termination of Employment. Notwithstanding the provisions of
Section 2, Employee's employment hereunder may terminate under any of the
following conditions:

                           A.       Death. Employee's employment under this
                  Agreement shall terminate automatically upon his death.

                           B.       Disability. Employee's employment under this
                  Agreement may be terminated due to his Disability.
                  "Disability" shall mean Employee's inability to substantially
                  perform his duties hereunder for any period of at least 180
                  consecutive days due to a physical or mental incapacity. The
                  date of termination due to Disability shall be the date
                  Employee elects to terminate his employment service due to
                  such Disability or, if earlier, the date the Board determines
                  that Employee has met the definition of Disability and given
                  written notice of such termination to Employee.

                           C.       Termination by Company Without Cause. The
                  Company may terminate Employee's employment hereunder without
                  Cause (as hereinafter defined) on 30 days' prior written
                  notice to Employee.

                           D.       Termination by Company for Cause. Employee's
                  employment hereunder may be terminated for Cause by the
                  Company. For purposes of this Agreement, "Cause" shall mean
                  (i) the willful and continued failure by Employee to
                  substantially perform Employee's duties with the Company
                  (other than any such failure resulting from Employee's
                  incapacity due to physical or mental illness), (ii) an act or
                  acts of dishonesty taken by Employee and intended to result in
                  personal enrichment of Employee at the expense of the Company,
                  (iii) willful violation by Employee of Employee's material
                  obligations under this Agreement, (iv) willful violation by
                  Employee of a material policy of the Company, including its
                  policies regarding professional and ethical conduct, (v)
                  Employee's commission of one or more acts that constitute a
                  felony, (vi) Employee is publicly censured by the Securities
                  Exchange Commission, or (vii) Employee commits one or more
                  acts of fraud as regards the Company. For purposes of clause
                  (i) of this definition, no act, or failure to act, on
                  Employee's part shall be deemed "willful" unless done, or
                  omitted to be done, by Employee not in good faith and without
                  reasonable belief that Employee's act, or failure to act, was
                  in the best interest of the Company. The determination of
                  whether Cause exists must be made by a resolution duly adopted
                  by the affirmative vote of not less than a majority of the
                  entire membership of the Board of Directors of the Company.

                           E.       Termination by Employee. Employee may
                  terminate his employment hereunder at any time on 30 days'
                  prior written notice to the Board.

                           determining Employee's vesting under any Options, the
                           number of shares that would become vested under such
                           Options during the 12-month period following
                           Employee's termination date if Employee's employment
                           had continued during such period shall become vested
                           on his termination of employment date, whichever of
                           (a) or (b) is elected by Employee in writing to the
                           Company within five days of his termination date.

                           C.       In the event of any termination of

                  that he may obtain.

                           D.       If within two years of the Effective Date
                  either Employee terminates his employment with the Company

                  the Company all unamortized relocation expenses paid by the

                           E.       The Company and Employee have previously or
                  contemporaneously with this Agreement entered into a Severance
                  Agreement which provides certain payments and benefits to
                  Employee upon a qualified termination of employment in
                  connection with a change of control of the Company.
                  Notwithstanding anything in this Agreement to the contrary, to
                  the extent Employee is entitled to receive any severance
                  payment or benefits under the Severance Agreement any
                  severance payment or benefits to which Employee is otherwise
                  entitled to receive under this Agreement shall be reduced or
                  offset by the severance payment or benefit payable under the
                  Severance Agreement in such manner as is appropriate, as
                  determined in good faith by the Board, to prevent a
                  duplication of such payment and benefits.

         SECTION 7. Indemnification. The Company agrees to indemnify Employee to
the fullest extent permitted by applicable law with respect to any acts or
non-acts he may have committed during the period which he was an officer,
director and/or employee of the Company or any subsidiary or affiliate thereof,
or of any other entity of which he served as an officer, director or employee at
the request of the Company.

         SECTION 8. Covenants of Employee. Employee covenants as follows:

                           A.       Confidentiality. During and after his
                  employment with the Company and its affiliates, Employee will
                  hold in confidence all confidential information and will not
                  disclose it to any person other than in connection with the
                  performance of his duties and obligations hereunder, except
                  with the specific prior written consent of the Board of
                  Directors or the Chief Executive Officer; provided, however,
                  that the parties agree that this Agreement does not prohibit
                  the disclosure of confidential information where applicable
                  law requires, including, but not limited to, in response of
                  subpoenas and/or orders of a governmental agency or court of
                  competent jurisdiction. In the event that Employee is
                  requested or becomes legally compelled under the terms of a
                  subpoena or order issued by a court of competent jurisdiction
                  or by a governmental body to make any disclosure of
                  confidential information, Employee agrees that he will (i)
                  immediately provide the Company with written notice of the
                  existence, terms and circumstances, surrounding such
                  request(s) so that the Company may seek an appropriate
                  protective order or other appropriate remedy, (ii) cooperate
                  with the Company in its efforts to decline, resist or narrow
                  such requests and (iii) if disclosure of such confidential
                  information is required in the opinion of counsel, exercise
                  reasonable efforts to obtain an order or other reliable
                  assurance that confidential treatment will be accorded to such
                  disclosed information. "Confidential information" means any
                  and all intellectual property of the Company (or any of its
                  affiliates), including but not limited to: (a) trade secrets
                  concerning the business and affairs of the Company (or any of
                  its affiliates), product specifications, data, know-how,
                  formulae, compositions, processes, designs, sketches,

                  by or for the Company (or any of its affiliates) containing or
                  based, in whole or in part, on any information included in the
                  foregoing.

                           B.       Trade Secrets. Any trade secrets of the
                  Company will be entitled to all of the protections and
                  benefits under the federal and state trade secret and
                  intellectual property laws and any other applicable law. If
                  any information that the Company deems to be a trade secret is
                  found by a court of competent jurisdiction not to be a trade
                  secret for purposes of this Agreement, such information will,
                  nevertheless, be considered confidential information for
                  purposes of this Agreement, so long as it otherwise meets the
                  definition of confidential information. Employee hereby waives
                  any requirement that the Company submit proof of the economic
                  value of any trade secret or post a bond or other security.

                           C.       Proprietary Items. Employee will not remove
                  from the Company's premises (except to the extent such removal
                  is for purposes of the performance of Employee's duties at
                  home or while traveling, or except as otherwise specifically
                  authorized by the Company) any document, record, notebook,
                  plan, model, component, device, or computer software or code,
                  whether embodied in a disk or in any other form belonging to
                  the Company or used in the Company's business (collectively,
                  the "Proprietary Items"). All of the Proprietary Items,
                  whether or not developed by Employee, are the exclusive
                  property of the Company. Upon termination of his employment,
                  or upon the request of the Company during the Term, Employee
                  will return to the Company all of the Proprietary Items and
                  confidential information in Employee's possession or subject
                  to Employee's control, and Employee shall not retain any
                  copies, abstracts, sketches, or other physical embodiment,
                  including electronic or otherwise, of any of the Proprietary
                  Items or confidential information.

                           D.       Non-Competition and Non-Interference. During
                  the period of his employment with the Company or its
                  affiliates and for the one-year period after the termination
                  of his employment with the Company and its affiliates,
                  Employee will not, directly or indirectly:

                                    1.       without the express prior written
                           consent of the Board of Directors, own an interest
                           in, manage, operate, join, control, lend money

                                      -6-

                           or render financial or other assistance to or
                           participate in or be connected with, as an officer,
                           employee, partner, stockholder, consultant or
                           otherwise, any person that competes with the Company
                           in the field of neurostimulation in a matter covered
                           by a patent assigned to or held by the Company;
                           provided, however, that following Employee's
                           termination of employment with the Company the
                           foregoing restriction shall apply only to those areas
                           where the Company is actually doing business on the
                           date of such termination of employment; provided,
                           further, that Employee may purchase or otherwise
                           acquire for passive investment up to 3% of any class
                           of securities of any such enterprise if such
                           securities are listed on any national or regional
                           securities exchange or have been registered under
                           Section 12(g) of the Securities Exchange Act of 1934;

                                    2.       whether for Employee's own account
                           or for the account of any other person, (except for
                           the account of the Company and its affiliates),
                           solicit Business from any person known by Employee to
                           be a customer of the Company or its affiliates,
                           whether or not Employee had personal contact with
                           such person during Employee's employment with the
                           Company and its affiliates;

                                    3.       whether for Employee's own account
                           or the account of any other person, (i) solicit,
                           employ, or otherwise engage as an employee,
                           independent contractor, or otherwise, any person who
                           is an employee of the Company or an affiliate, or in
                           any manner induce, or attempt to induce, any employee
                           of the Company or its affiliate to terminate his
                           employment with the Company or its affiliate; or (ii)
                           interfere with the Company's or its affiliate's
                           relationship with any person who at any time during
                           the Term, was an employee, contractor, supplier, or
                           customer of the Company or its affiliate; or

                                    4.       at any time after the termination
                           of his employment, disparage the Company or its
                           affiliates or any shareholders, directors, officers,
                           employees, or agents of the Company or any of its
                           affiliates, so long as the Company does not disparage
                           Employee.

                           E.       Acknowledgements. The Company acknowledges
                  that it is providing Employee with confidential information in
                  order for Employee to perform his duties under this Agreement.
                  Employee acknowledges that (a) the services to be performed by
                  him under this Agreement are of a special, unique, unusual,
                  extraordinary, and intellectual character, and (b) the
                  provisions of this Section 8 are reasonable and necessary to
                  protect the confidential information, goodwill and other
                  business interests of the Company. If any covenant in this
                  Section 8 is held to be unreasonable, arbitrary, or against
                  public policy, such covenant will be considered to be
                  divisible with respect to scope, time, and geographic area,
                  and such lesser scope, time, or geographic area, or all of
                  them, as a court of competent jurisdiction may determine to be
                  reasonable, not arbitrary, and not against public policy, will
                  be effective, binding, and enforceable against

                                      -7-
<PAGE>

                  Employee. Employee hereby agrees that this covenant is a
                  material and substantial part of this Agreement and that: (i)
                  the geographic limitations are reasonable; (ii) the term of
                  the covenant is reasonable; and (iii) the covenant is not made
                  for the purpose of limiting competition per se and is
                  reasonably related to a protectable business interest of the
                  Company. The period of time applicable to any covenant in this
                  Section 8 will be extended by the duration of any violation by
                  Employee of such covenant. The provisions of this Section 8
                  shall survive the termination of the Term of this Agreement.

         SECTION 9. Injunctive Relief and Additional Remedy. Employee
acknowledges that the injury that would be suffered by the Company as a result
of a breach of the provisions of Section 8 of this Agreement would be
irreparable and that an award of monetary damages to the Company for such a
breach would be an inadequate remedy. Consequently, the Company will have the
right, in addition to any other rights it may have, to obtain a temporary
restraining order and/or injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this Agreement.
Employee waives any requirement for the Company's securing or posting of any
bond in conjunction with any such remedies. Employee further agrees to and
hereby does submit to in personam jurisdiction before each and every court for
that purpose. Without limiting the Company's rights under this Section or any
other remedies of the Company, if Employee breaches any of the provisions of
Section 8 and such breach is proven in a court of competent jurisdiction, the
Company will have the right to cease making any payments or providing other
benefits otherwise due Employee under this Agreement.

         SECTION 10. Amendment; Waiver. The terms and provisions of this
Agreement may be modified or amended only by a written instrument executed by
each of the parties hereto, and compliance with the terms and provisions hereof
may be waived only by a written instrument executed by each party entitled to
the benefits thereof. No failure or delay on the part of any party in exercising
any right, power or privilege granted hereunder shall constitute a waiver
thereof, nor shall any single or partial exercise of any such right, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, power or privilege granted hereunder.

         SECTION 11. Entire Agreement. Except as contemplated herein and the
Severance Agreement referenced in Section 6.D., this Agreement constitutes the
entire agreement between the parties with respect to the subject matter hereof
and supersedes any and all prior or contemporaneous written or oral agreements,
arrangements or understandings between the Company and Employee.

legality and enforceability of the remaining terms and provisions hereof shall

points above the interest rate applicable immediately prior to the occurrence of
the Event of Default.

             (c) Payments. Interest hereunder shall be due and payable on the
first calendar day of each month during the term hereof. Bank shall, at its
option, charge such interest, all Bank Expenses, and all Periodic payments
against any of a Borrower's deposit accounts or against the Revolving Line, in
which case those amounts shall thereafter accrue interest at the rate then
applicable hereunder. Any interest not paid when due shall be compounded by
becoming a part of the Obligations, and such interest shall thereafter accrue
interest at the rate then applicable hereunder. All payments shall be free and
clear of any taxes, withholdings, duties, impositions or other charges, to the
end that. Bank will receive the entire amount of any Obligations payable
hereunder, regardless of source of payment.

             (d) Computation. In the event the Prime Rate is changed from time
to time hereafter, the applicable rate of interest hereunder shall be increased
or decreased, effective as of the day the Prime Rate is changed, by an amount
equal to such change in the Prime Rate. All interest chargeable under the Loan
Documents shall be computed on the basis of a three hundred sixty (360) day year

         2.4 Crediting Payments. Prior to the occurrence of an Event of Default,

or other item of payment shall be immediately applied to conditionally reduce
Obligations, but shall not be considered a payment on account unless such
payment is of immediately available federal funds or unless and until such check
or other item of payment is honored when presented for payment. Notwithstanding
anything to the contrary contained herein, any wire transfer or payment received
by Bank after 12:00 noon Pacific time shall be deemed to have been received by
Bank as of the opening of business on the immediately following Business Day.
Whenever any payment to Bank under the Loan Documents would otherwise be due
(except by reason of acceleration) on a date that is not a Business Day, such
payment shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of such
extension.

         2.6 Additional Costs. In case any law, regulation, treaty or official
directive or the interpretation or application thereof by any court or any
governmental authority charged with the administration thereof or the compliance
with any guideline or request of any central bank or other governmental
authority (whether or not having the force of law):

             (a) subjects Bank to any tax with respect to payments of principal
or interest or any other amounts payable hereunder by Borrowers or otherwise

overall net income of Bank imposed by the United States of America or any
political subdivision thereof);

performance under this Agreement,

to pay to Bank the amount of such increase in cost, reduction in income or
additional expense as and when such cost, reduction or expense is incurred or
determined, upon presentation by Bank of a statement of the amount and setting
forth Bank's calculation thereof, all in reasonable detail, which statement
shall be deemed true and correct absent manifest error.

         2.7 Term. This Agreement shall become effective on the Closing Date
and, subject to Section 12.7, shall continue in full force and effect for so
long as any Obligations remain outstanding or Bank has any obligation to make
Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank
shall have the right to terminate its obligation to make Credit Extensions under
this Agreement immediately and without notice upon the occurrence and during

its covenants and duties under the Loan Documents. Except as set forth in the
Schedule, such security interest constitutes a valid, first priority security
interest in the presently existing Collateral, and will constitute a valid,
first priority security interest in Collateral acquired after the date hereof.

following the occurrence of an Event of Default, Borrower shall maintain a money
market account or certificate of deposit with Bank with a balance equal to or

Obligations, a valid, first priority security interest in such money market
account or certificate of deposit maintained by Borrower with Bank, including,
without limitation, all amounts held therein, together with all proceeds
thereof, interest paid thereon, and substitutions therefor, and all accounts,
securities, instruments, securities entitlements and financial assets arising

and/or file such documents, and take such actions, as Bank determines reasonable
to perfect its security interest in the Cash Collateral. Such security interest
constitutes a valid, first priority security interest in the Cash Collateral,
and will constitute a valid, first priority security interest in Cash Collateral

Borrower's assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of a Borrower's material assets by the United States
Government, or any department, agency, or instrumentality thereof, or by any
state, county, municipal, or governmental agency, and the same is not paid
within ten (10) days after a Borrower receives notice thereof, provided that
none of the foregoing shall constitute an Event of Default where such action or
event is stayed or an adequate bond has been posted pending a good faith contest
by Borrowers (provided that no Credit Extensions will be required to be made
during such cure period);

         8.5 Insolvency. If a Borrower becomes insolvent (i.e., Borrower is

commenced against a Borrower and is not dismissed or stayed within thirty (30)
days (provided that no Credit Extensions will be made prior to the dismissal of
such Insolvency Proceeding);

         8.6 Other Agreements. If there is a default or other failure to perform
in any agreement to which a Borrower is a party or by which it is bound
resulting in a right by a third party or parties, whether or not exercised; to
accelerate the maturity of any Indebtedness in an amount in excess of One
Hundred Thousand Dollars ($100,000); or which could have a Material Adverse
Effect;

         8.7 Subordinate Debt. If Borrower makes any payment on account of

         8.8 Judgments. If a judgment or judgments for the payment of money in
an amount, individually or in the aggregate, of at least Five Hundred Thousand
Dollars ($500,000) shall be rendered against a Borrower and shall remain
unsatisfied and unstayed for a period of ten (10) days (provided that no Credit
Extensions will be made prior to the satisfaction or stay of such judgment); or

         8.9 Misrepresentations. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth
herein or in any certificate delivered to Bank by any Responsible Officer
pursuant to this Agreement or to induce Bank to enter into this Agreement or any
other Loan Document.

                                                                            -22-

         9.  BANK'S RIGHTS AND REMEDIES.

             9.1 Rights and Remedies. Upon the occurrence and during the
continuance of an Event of Default, Bank may at its elections without notice of
its election and without demand do any one or more of the following, all of
which are authorized by each Borrower:

                 (a) Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5, all Obligations shall become immediately due and payable without
any action by Bank);

                 (b) Cease advancing money or extending credit to or for the
benefit of Borrower under this Agreement or under any other agreement between
Borrower and Bank;

                 (c) Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;

                 (d) Make such payments and do such acts as Bank considers
necessary or reasonable to protect its security interest in the Collateral.
Borrower agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate. Borrower authorizes Bank to
enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or lien which in Bank's determination
appears to be prior or superior to its security interest and to pay all expenses
incurred in connection therewith. With respect to any of Borrower's owned
premises, Borrower hereby grants Bank a license to enter into possession of such
premises and to occupy the same, without charge, in order to exercise any of
Bank's rights or remedies provided herein, at law, in equity, or otherwise;

                 (e) Set off and apply to the Obligations any and all (i)
balances and deposits of Borrower held by Bank, or (ii) indebtedness at any time
owing to or for the credit or the account of Borrower held by Bank;

                 (f) Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

                 (g) Dispose of the Collateral by way of one or more contracts
or transactions, for cash or on terms; in such manner and at such places
(including Borrower's premises) as Bank determines is commercially reasonable,
and apply any proceeds to the Obligations in whatever manner or order Bank deems
appropriate;

                                                                            -23-
<PAGE>

                 (h) Bank may credit bid and purchase at any public sale; and

                 (i) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

             9.2 Power of Attorney. Effective only upon the occurrence and
during the continuance of an Event of Default, each Borrower hereby irrevocably
appoints Bank (and any of Bank's designated officers, or employees) as such
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of Bank's security interest in the Accounts;
(b) endorse Borrower's name on any checks or other forms of payment or security
that may come into Bank's possession; (c) sign Borrower's name on any invoice or
bill of lading relating to any Account, drafts against account debtors,
schedules and assignments of Accounts, verifications of Accounts, and notices to
account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all
claims under and decisions with respect to Borrower's policies of insurance; (f)
settle and adjust disputes and claims respecting the accounts directly with
account debtors, for amounts and upon terms which Bank determines to be
reasonable; and (g) to file, in its sole discretion, one or more financing or
continuation statements and amendments thereto, relative to any of the
Collateral; provided Bank may exercise such power of attorney to sign the name
of Borrower on any of the documents described in Section 4.2 regardless of
whether an Event of Default has occurred. The appointment of Bank as each
Borrower's attorney in fact, and each and every one of Bank's rights and powers,
being coupled with an interest, is irrevocable until all of the Obligations have
been fully repaid and performed and Bank's obligation to provide Credit
Extensions hereunder is terminated.

             9.3 Accounts Collection. Upon the occurrence and during the
continuance of an Event of Default, Bank may notify any Person owing funds to a
Borrower of Bank's security interest in such funds and verify the amount of such
Account. Each Borrower shall collect all amounts owing to such Borrower for
Bank, receive in trust all payments as Bank's trustee, and immediately deliver
such payments to Bank in their original form as received from the account
debtor, with proper endorsements for deposit.

             9.4 Bank Expenses. If a Borrower fails to pay any amounts or
furnish any required proof of payment due to third persons or entities, as
required under the terms of this Agreement, then Bank may do any or all of the
following after reasonable notice to Borrowers: (a) make payment of the same or
any part thereof; (b) set up such reserves under a loan facility in Section 2.1
as Bank deems necessary to protect Bank from the exposure created by such
failure; or (c) obtain and maintain insurance policies of the type discussed in
Section 6.6 of this Agreement, and take any action with respect to such policies
as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute
Bank Expenses, shall be immediately due and payable, and shall bear interest at
the then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by Bank
to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

             9.5 Bank's Liability for Collateral. So long as Bank complies with
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or

                                                                            -24-
<PAGE>

fashion from any cause; (c) any diminution in the value thereof or (d) any act
or default of any carrier, warehouseman, bailee, forwarding agency, or other
person whomsoever. All risk of loss, damage or destruction of the Collateral
shall be borne by Borrowers except to the extent such loss, damage or
destruction was caused by Bank's gross negligence or misconduct.

             9.6 Remedies Cumulative. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on a Borrower's part shall be deemed a continuing waiver. No delay by
Bank shall constitute a waiver, election, or acquiescence by it. No waiver by
Bank shall be effective unless made in a written document signed on behalf of
Bank and then shall be effective only in the specific instance and for the
specific purpose for which it was given.

             9.7 Demand; Protest. Each Borrower waives demand, protest, notice
of protest, notice of default or dishonor, notice of payment and nonpayment,
notice of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which a Borrower may in any way be
liable.

         10. NOTICES.

         11. CHOICE OF LAW AND VENUE- JURY TRIAL WAIVER.

         This Agreement shall be governed by, and construed in accordance with,
the internal laws of the State of California, without regard to principles of
conflicts of law. Each Borrower and Bank hereby submits to the exclusive
jurisdiction of the state and Federal courts located in the County of Santa
Clara, State of California. BORROWERS AND BANK EACH HEREBY WAIVE THEIR
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED
THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL
OTHER COMMON LAW OR STATUTORY CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE
FOREGOING WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS
AGREEMENT. EACH PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER
WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY
TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

         12. GENERAL PROVISIONS.

             12.1 Successors and Assigns. This Agreement shall bind and inure to
the benefit of the respective successors and permitted assigns of each of the
parties; provided, however, that neither this Agreement nor any rights hereunder
may be assigned by a Borrower without Bank's prior written consent, which
consent may be granted or withheld in Bank's sole discretion. Bank shall have
the right without the consent of or notice to Borrowers to sell, transfer,
negotiate, or grant participation in all or any part of, or any interest in,
Bank's obligations, rights and benefits hereunder.

             12.2 Indemnification. Each Borrower shall defend, indemnify and
hold harmless Bank and its officers, employees, and agents against: (a) all
obligations, demands, claims, and

                                                                            -26-
<PAGE>

liabilities claimed or asserted by any other party in connection with the
transactions contemplated by this Agreement; and (b) all losses or Bank Expenses
in any way suffered, incurred, or paid by Bank as a result of or in any way
arising out of, following, or consequential to transactions between Bank and a
Borrower whether under this Agreement, or otherwise (including without
limitation reasonable attorneys' fees and expenses), except for losses caused by
Bank's gross negligence or willful misconduct.

             12.3 Time of Essence. Time is of the essence for the performance of
all obligations set forth in this Agreement.

             12.4 Severability of Provisions. Each provision of this Agreement
shall be severable from every other provision of this Agreement for tire purpose
of determining the legal enforceability of any specific provision.

             12.5 Amendments in Writing, Integration. Neither this Agreement nor
the Loan Documents can be amended or terminated orally. All prior agreements,
understandings, representations, warranties, and negotiations between the
parties hereto with respect to the subject matter of this Agreement and the Loan
Documents, if any, are merged into this Agreement and the Loan Documents.

             12.6 Counterparts. This Agreement may be executed in any number of
counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same Agreement.

             12.7 Survival. All covenants, representations and warranties made
in this Agreement shall continue in full force and effect so long as any
Obligations remain outstanding or Bank has any obligation to make Credit
Extensions to Borrowers. The obligations of each Borrower to indemnify Bank with
respect to the expenses, damages, losses, costs and liabilities described in
Section 12.2 shall survive until all applicable statute of limitations periods
with respect to actions that may be brought against Bank have run.

         13. CO-BORROWER PROVISIONS.

             13.1 Primary Obligation. This Agreement is a primary and original
obligation of each Borrower and shall remain in effect notwithstanding future
changes in conditions, including any change of law or any invalidity or
irregularity in the creation or acquisition of any Obligations or in the
execution or delivery of any agreement between Bank and any Borrower. Each
Borrower shall be liable for existing and future Obligations as fully as if all
of all Credit Extensions were advanced to such Borrower. Bank may rely on any
certificate or representation made by any Borrower as made on behalf of, and
binding on, all Borrowers, including without limitation Disbursement Request
Forms, Borrowing Base Certificates and Compliance Certificates.

                                                                            -27-
<PAGE>

             13.2 Enforcement of Rights. Borrowers are jointly and severally
liable for the Obligations and Bank may proceed against one or more of the
Borrowers to enforce the Obligations without waiving its right to proceed
against any of the other Borrowers.

             13.3 Borrowers as Agents. Each Borrower appoints the other Borrower
as its agent with all necessary power and authority to give and receive notices,
certificates or demands for and on behalf of both Borrowers, to act as
disbursing agent for receipt of any Credit Extensions on behalf of each Borrower
and to apply to Bank on behalf of each Borrower for Credit Extensions, any
waivers and any consents. This authorization cannot be revoked, and Bank need
not inquire as to each Borrower's authority to act for or on behalf of Borrower.

             13.4 Subrogation and Similar Rights. Notwithstanding any other
provision of this Agreement or any other Loan Document, each Borrower
irrevocably waives all rights that it may have at law or in equity (including,
without limitation, any law subrogating the Borrower to the rights of Bank under
the Loan Documents) to seek contribution, indemnification, or any other form of
reimbursement from any other Borrower, or any other Person now or hereafter
primarily or secondarily liable for any of the Obligations, for any payment made
by the Borrower with respect to the Obligations in connection with the Loan
Documents or otherwise and all rights that it might have to benefit from, or to
participate in, any security for the Obligations as a result of any payment made
by the Borrower with respect to the Obligations in connection with the Loan
Documents or otherwise. Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this Section 12.4 shall
be null and void. If any payment is made to a Borrower in contravention of this
Section 12.4, such Borrower shall hold such payment in trust for Bank and such
payment shall be promptly delivered to Bank for application to the Obligations,
whether matured or unmatured.

             13.5 Waivers of Notice. Except as otherwise provided in this
Agreement, each Borrower waives notice of acceptance hereof; notice of the
existence, creation or acquisition of any of the Obligations; notice of an Event
of Default; notice of the amount of the Obligations outstanding at any time;
notice of intent to accelerate; notice of acceleration; notice of any adverse
change in the financial condition of any other Borrower or of any other fact
that might increase the Borrower's risk; presentment for payment; demand;
protest and notice thereof as to any instrument; default; and all other notices
and demands to which the Borrower would otherwise be entitled. Each Borrower
waives any defense arising from any defense of any other Borrower, or by reason
of the cessation from any cause whatsoever of the liability of any other
Borrower. Bank's failure at any time to require strict performance by any
Borrower of any provision of the loan Documents shall not waive, alter or
diminish any right of Bank thereafter to demand strict compliance and
performance therewith. Nothing contained herein shall prevent Bank from
foreclosing on the Lien of any deed of trust, mortgage or other security
instrument, or exercising any rights available thereunder, and the exercise of
any such rights shall not constitute a legal or equitable discharge of any
Borrower. Each Borrower also waives any defense arising from any act or omission
of Bank that changes the scope of the Borrower's risks hereunder.

                                                                            -28-
<PAGE>

             13.6 Subrogation Defenses. Each Borrower hereby waives any defense
based on impairment or destruction of its subrogation or other rights against
any other Borrower and waives all benefits which might otherwise be available to
it under California Civil Code Sections 2809, 2810, 2819, 2839, 2845, 2848,
2849, 2850, 2899, and 3433 and California Code of Civil Procedure Sections 580a,
580b, 580d and 726, as those statutory provisions are now in effect and
hereafter amended, and under any other similar statutes now and hereafter in
effect.

             13.7 Right to Settle, Release.

                  (a) The liability of Borrowers hereunder shall not be
diminished by (i) any agreement, understanding or representation that any of the
Obligations is or was to be guaranteed by another Person or secured by other
property, or (ii) any release or unenforceability, whether partial or total, of
rights, if any, which Bank may now or hereafter have against any other Person,
including another Borrower, or property with respect to any of the Obligations.

                  (b) Without affecting the liability of any Borrower hereunder,
Bank may (i) compromise, settle, renew, extend the time for payment, change the
manner or terms of payment, discharge the performance of, decline to enforce, or
release all or any of the Obligations with respect to a Borrower, (ii) grant
other indulgences to a Borrower in respect of the Obligations, (iii) modify in
any manner any documents relating to the Obligations with respect to a Borrower,
(iv) release, surrender or exchange any deposits or other property securing the
Obligations, whether pledged by a Borrower or any other Person, or (v)
compromise, settle, renew, or extend the time for payment, discharge the
performance of, decline to enforce, or release all or any obligations of any
guarantor; endorser or other Person who is now or may hereafter be liable with
respect to any of the Obligations.

             13.8 Subordination. All indebtedness of a Borrower now or hereafter
arising held by another Borrower is subordinated to the Obligations and the
Borrower holding the indebtedness shall take all actions reasonably requested by
Lender to effect, to enforce and to give notice of such subordination.

                                                                            -29-

Litigation (Section 5.8)

         On November 14, 2001, a shareholder class action complaint was filed in
the United States District Court, Southern District of New York. On April 19,
2002, plaintiffs filed an amended complaint. The amended complaint asserts that
the prospectus from the Company's February 10, 2000 initial public offering
("IPO") failed to disclose certain alleged improper actions by various
underwriters for the offering in the allocation of the IPO shares. The amended
complaint alleges claims against certain underwriters, the Company and certain
officers and directors under the Securities Act of 1933 and the Securities
Exchange Act of 1934 (Bartula v. XCare.net, Inc., et al., Case No. 01-CV-10075).
Similar complaints have been filed concerning more than 300 other IPO's; all of
these cases have been coordinated as In re Initial Public Offering Securities
Litigation, 21 MC 92, In a negotiated agreement, individual defendants,
including all of the individuals named in the complaint filed against the
Company, were dismissed without prejudice, subject to a tolling agreement.
Issuer and underwriter defendants in these cases filed motions to dismiss and,
on February 19, 2003, the Court issued an opinion and order on those motions
that dismissed selected claims against certain defendants, including the Rule
l0b-5 fraud claims against the Company, leaving only the Section 11 strict
liability claims under the Securities Act of 1933 against the Company. A
committee of our Board of Directors has approved a settlement proposal made by
the plaintiffs, but the settlement is subject to a number of conditions. If the
settlement is not achieved, the Company will continue to aggressively defend the
claims. The Company believes it has meritorious defenses. We do not believe that
the outcome of this action will have a material adverse effect on our financial
position, results of operations or liquidity; however, litigation is inherently
uncertain and we can make no assurance as to the ultimate outcome or effect.
