                                       3
<PAGE>

      (b) The Board shall have the power, subject to, and within the limitations
of, the express provisions of the Plan:

            (1) To determine from time to time which of the persons eligible
under the Plan shall be granted Awards; when and how each Award shall be
granted; in the case of Options, whether an Option will be an Incentive Stock
Option or a Nonstatutory Stock Option; the provisions of each Award granted
(which need not be identical), including, with respect to Options, the time or
times such Options may be exercised in whole or in part; and the number of
shares for which an Award be granted to each such person.

            (2) To construe and interpret the Plan and Awards granted under it,
and to establish, amend and revoke rules and regulations for its administration.
The Board, in the exercise of this power, may correct any defect, omission or
inconsistency in the Plan or in any Option Agreement or Stock Purchase
Agreement, in a manner and to the extent it shall deem necessary or expedient to
make the Plan fully effective.

            (3)   To amend the Plan or an Award as provided in Section 13.

            (4) Generally, to exercise such powers and to perform such acts as
the Board deems necessary or expedient to promote the best interests of the
Company which are not in conflict with the provisions of the Plan.

      (c) The Board may delegate administration of the Plan to a committee (the
"COMMITTEE") consisting of two or more Directors, each of whom is an "outside
director" within the meaning of Section 162(m) of the Code and a "non-employee
director" within the meaning of Section 16b-3 promulgated under the Exchange
Act. Such Committee, if so appointed, shall have the powers theretofore
possessed by the Board (and references in this Plan to the Board shall
thereafter be to such Committee), subject, however, to such resolutions, not
inconsistent with the provisions of the Plan, as may be adopted from time to
time by the Board. The foregoing notwithstanding, the Board may abolish such
Committee at any time and revest in the Board the administration of the Plan.

4.    Shares Subject to the Plan.

      (a) Subject to the provisions of Section 12 relating to adjustments upon
changes in the Common Stock, the Common Stock that may be issued pursuant to
Awards shall not exceed in the aggregate four million (4,000,000) shares. If any
Award shall for any reason expire or otherwise terminate, in whole or in part,
without having been exercised in full, the stock not purchased under such Award
shall revert to and again become available for issuance under the Plan. In
addition, shares of Common Stock acquired by the Company pursuant to its
exercise of a Right of Repurchase shall revert to and again become eligible for
issuance under the Plan.

      (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

      (c) The number of shares of Common Stock for which an Award may be granted
in any single fiscal year of the Company to any participant in the Plan shall
not exceed 600,000 shares (the "INDIVIDUAL LIMIT"). The Individual Limit shall
be construed and applied


                                       4
<PAGE>

consistently with Section 162(m) of the Code. For purposes of the foregoing
limitation, if any Award is canceled, the canceled Award shall continue to be
counted against the Individual Limit. If after grant the Purchase Price of an
Award is modified, the transaction shall be treated as the cancellation of the
Award and the grant of a new Award; in any such case, both the Award that is
canceled and the Award deemed to be granted shall be counted against the
Individual Limit.

5.    Eligibility to Receive Options.

      (a) Incentive Stock Options may be granted only to Employees. Nonstatutory
Stock Options may be granted only to Employees, Directors or Consultants.

      (b) No person shall be eligible for the grant of an Incentive Stock Option
if, at the time of grant, such person owns (or is deemed to own pursuant to
Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or any of its
Affiliates unless the exercise price of such Incentive Stock Option is at least
one hundred ten percent (110%) of the Fair market Value of such stock at the
date of grant and the Incentive Stock Option is not exercisable after the
expiration of five (5) years from the date of grant. To the extent required by
applicable law, the provisions of this subsection 5(b) shall also apply to the
grant of a Nonstatutory Stock Option granted to a ten percent (10%) stockholder
described in the preceding sentence.

6.    Option Provisions.

      Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

      (a)   Term.  No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

      (b) Price. The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value on the date of
grant. The exercise price of each Nonstatutory Stock Option shall be as
determined by the Board at the time such Option is granted. Notwithstanding the
foregoing, the Board may grant an Incentive Stock Option with an exercise price
lower than that set forth above if such Option is granted as part of a
transaction to which section 424(a) of the Code applies.

      (c) Consideration. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board, at the time of the grant of the Option, (A) by
delivery to the Company of other capital stock of the Company, (B) according to
a deferred payment or other arrangement (which may include, without limiting the
generality of the foregoing, the use of other capital stock of the Company) with
the person to whom the Option is granted or to whom the Option is transferred
pursuant to subsection 6(d) (but no deferred payment of the Common Stock's par
value may be made unless permitted by applicable law), or (C) by delivery to the
Company of irrevocable instructions to a broker to (i) either sell


                                       5
<PAGE>

the shares subject to the Option being exercised or hold such shares as
collateral for a margin loan and (ii) promptly deliver to the Company the amount
of the sale or loan proceeds required to pay the exercise price or (D) in any
other form of legal consideration that may be acceptable to the Board.

      In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate of interest necessary
to avoid the treatment as interest, under any applicable provisions of the Code,
of any amounts other than amounts stated to be interest under the deferred
payment arrangement.

      (d) Transferability. An Option shall not be transferable except by will or
by the laws of descent and distribution, and shall be exercisable during the
lifetime of the person to whom the Option is granted only by such person. The
Participant to whom the Option is granted may, by delivering written notice to
the Company, in a form satisfactory to the Company, designate a third party who,
in the event of the death of the Participant, shall thereafter be entitled to
exercise the Option.

      (e) Vesting. The total number of shares of stock subject to an Option may,
but need not, be allotted in periodic installments (which may, but need not, be
equal). The Option Agreement may provide that from time to time during each of
such installment periods, the Option may become exercisable ("VEST") with
respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or period as to which the Option became vested but was not fully exercised.
The Option may be subject to such other terms and conditions on the time or
times when it may be exercised (which may be based on performance or other
criteria) as the Board may deem appropriate. The provisions of this subsection
6(e) are subject to any Option provisions governing the minimum number of shares
as to which an Option may be exercised.

      (f) Securities Law Compliance. The Company may require any Participant, or
any person to whom an Option is transferred under subjection 6(d), as a
condition of exercising any such Option, (1) to give written assurances
satisfactory to the Company as to the Participant's knowledge and experience in
financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in
financial and business matters, and that he or she is capable of evaluating,
alone or together with the purchaser representative, the merits and risks of
exercising the Option; and (2) to give written assurances satisfactory to the
Company stating that such person is acquiring the stock subject to the Option
for such person's own account and not with any present intention of selling or
otherwise distributing the stock. The foregoing requirements, and any assurances
given pursuant to such requirements, shall be inoperative if (i) the issuance of
the shares upon the exercise of the Option has been registered under a then
currently effective registration statement under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), or (ii) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may require the Participant to provide such other representations,
written assurances or information which the Company shall determine is
necessary, desirable or appropriate to comply with applicable securities and
other laws as a condition of granting an Option to such Participant or
permitting the Participant to exercise such Option. The Company may, upon advice
of counsel


                                       6
<PAGE>

to the Company, place legends on stock certificates issued under the Plan as
such counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of stock.

      (g) Termination of Continuous Status as an Employee, Director or
Consultant. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Participant's death or
disability), the Participant may exercise his or her Option (to the extent that
the Participant was entitled to exercise it as of the date of termination) but
only within such period of time ending on the earlier of (i) the Termination
Date, or (ii) the expiration date of the Option as set forth in the Option
Agreement (the "EXPIRATION DATE"). If, after termination, the Participant does
not exercise his or her Option within the time specified in the Option
Agreement, the Option shall terminate, and the shares covered by such Option
shall revert to and again become available for issuance under the Plan.

      A Participant's Option Agreement may also provide that if the exercise of
the Option following the termination of the Participant's Continuous Status as
an Employee, Director or Consultant (other than upon the Participant's death or
disability) and prior to the Termination Date would be prohibited at any time
solely because the issuance of shares would violate the registration
requirements under the Securities Act, the Termination Date shall be extended to
such date that would allow the Option to be exercisable without violation of
such restriction requirements for an aggregate period equal to the
Post-Termination Expiration Period (but in no event after the Expiration Date).

      (h) Disability of Participant. In the event a Participant's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Participant's total and permanent disability (as determined by the Board in its
sole discretion), the Participant may exercise his or her Option (to the extent
that the Participant was entitled to exercise it as of the date of termination)
but only within such period of time ending on the earlier of (i) the Expiration
Date, or (ii) the date that is the one-year anniversary of the termination of
the Participant's Continuous Status as an Employee, Director or Consultant. If,
after termination, the Participant does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

      (i) Death of Participant. In the event of the death of a Participant
during, or within a period specified in the Option Agreement after the
termination of, the Participant's Continuous Status as an Employee, Director or
Consultant, the Option may be exercised by the Participant's estate, by a person
who acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the option upon the Participant's death pursuant
to subsection 6(d), (to the extent that the Participant was entitled to exercise
it as of the date of termination) but only within such period of time ending on
the earlier of (i) the Expiration Date, or (ii) the date that is the one-year
anniversary of the termination of the Participant's Continuous Status as an
Employee, Director or Consultant. If, after the Participant's death, the Option
is not exercised within the time specified herein, the Option shall terminate,
and the shares covered by such Option shall revert to and again become available
for issuance under the Plan.


                                       7

7.    Stock Purchase Rights.

      Stock Purchase Rights may be issued either alone, in addition to, or in
tandem with Options granted under the Plan and/or other benefits or awards made
outside of the Plan. After the Board determines that it will offer a Stock
Purchase Right under the Plan, the Company shall advise the prospective
Participant in writing of the terms, conditions and restrictions related to the
offer, including the number of shares of Common Stock subject to the Stock
Purchase Right, the Purchase Price and the terms and conditions of the Right of
Repurchase applicable thereto and the time within which such prospective
Participant must accept such offer. Each Stock Purchase Right, and the
acceptance of the terms thereof by the Company and the Participant, shall be
evidenced by a Stock Purchase Agreement. Each Stock Purchase Agreement shall
contain such terms, provisions and conditions not inconsistent with the Plan as
may be determined by the Board, in its sole discretion.

8.    Right of Repurchase and Restricted Shares.

      (a) Each Option Agreement may, and, unless the Board determines otherwise,
each Stock Purchase Agreement shall, grant the Company a Right of Repurchase
exercisable upon the termination of the Participant's Continuous Status as an
Employee, Director or Consultant for any reason (including death or disability)
or upon the failure to satisfy any performance objectives or other conditions
specified in the applicable Option Agreement or Stock Purchase Agreement. The
Right of Repurchase shall lapse upon such conditions or at such rate as the
Board may determine and as shall be set forth in the applicable Option Agreement
or Stock Purchase Agreement. Shares of Common Stock issued as Restricted Shares
may not be sold, assigned, transferred, pledged or otherwise disposed of, except
by will or the laws of descent and distribution, or as otherwise determined by
the Board and set forth in the applicable Option Agreement or Stock Purchase
Agreement. Any attempt to dispose of Restricted Shares in contravention of the
Right of Repurchase shall be null and void and without effect.

      (b) The per share purchase price for Restricted Shares repurchased
pursuant to a Right of Repurchase shall be the Purchase Price paid by the
Participant for such Restricted Shares, and may be paid by cancellation of any
indebtedness of the Participant to the Company. Notwithstanding the foregoing,
the applicable Option Agreement or Stock Purchase Agreement may provide that the
per share purchase price for Restricted Shares repurchased pursuant to a Right
of Repurchase shall be less than the Purchase Price for such shares if the
Participant's Continuous Status as an Employee, Director or Consultant is
terminated by the Company or an Affiliate for Cause.

      (c) Each certificate for Restricted Shares shall bear an appropriate
legend referring to the Right of Repurchase, together with any other applicable
legends, and, upon issuance, shall be deposited by the stockholder with the
Company together with a stock power and such other instruments of transfer as
may be reasonably requested by the Company, duly endorsed in blank, if
appropriate; provided, however, that the failure of the Company or its transfer
agent to place such a legend on a certificate for Restricted Shares shall have
no effect on the Right of Repurchase applicable to such shares. If the Company
does not exercise the Right of Repurchase within the time and in the manner
specified in the applicable Option Agreement or Stock


                                       8
<PAGE>

Purchase Agreement, such Right of Repurchase shall terminate and be of no
further force and effect.

      (d) The Board may, in its sole discretion, waive the Company's Right of
Repurchase applicable to any Restricted Shares. Such waiver shall result in the
immediate vesting of the Participant's interest in the Restricted Shares as to
which the waiver applies. Such waiver may be effected at any time, whether
before or after the termination of the Participant's Continuous Status as an
Employee, Director or Consultant or the attainment or non-attainment of the
applicable conditions.

9.    Covenants of the Company.

      (a) Notwithstanding the second sentence of Section 14(a) hereof, so long
as any Awards remain outstanding under the Plan, the Company shall keep
available the number of shares of Common Stock required to satisfy such Awards.

      (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction of the Plan such authority as may be required to
issue and sell shares of Common Stock issued pursuant to Awards; provided,
however, that this undertaking shall not require the Company to register under
the Securities Act either the Plan, any Award or any Common Stock issued or
issuable pursuant to any such Award. If, after reasonable efforts, the Company
is unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of Common Stock issued pursuant to Awards granted under the Plan, the Company
shall be relieved from any liability for failure to issue and sell such Common
Stock unless and until such authority is obtained.

10.   Use of Proceeds.

      Proceeds from the sale of Common Stock pursuant to Awards shall constitute
general funds of the Company.

11.   Miscellaneous.

      (a) Acceleration of Vesting of Options. The Board shall have the power to
accelerate the time at which an Option may first be exercised or the time during
which an Option or any part thereof will vest pursuant to subsection 6(e),
notwithstanding the provisions in the Option stating the time at which it may
first be exercised or the time during which it will vest. In addition, the Board
shall have the power to waive the Right of Repurchase under any Award,
notwithstanding the provisions of the agreement evidencing such Award.

      (b) No Rights as a Stockholder. Neither a Participant who holds an
outstanding Option, nor any person to whom an Option is transferred under
subsection 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.


                                       9
<PAGE>

      (c) No Retention Rights. Nothing in the Plan or any instrument executed or
Award granted pursuant thereto shall confer upon any Participant any right to
continue in the employ of the Company or any of its Affiliates (or to continue
acting as a Director or Consultant) or shall affect the right of the Company or
any Affiliate to terminate the employment of any Employee with or without Cause,
the right of the Board and/or the Company's stockholders to remove any Director
pursuant to the terms of the Company's By-Laws and applicable law, or the right
to terminate the relationship of any Consultant pursuant to the terms of such
Consultant's agreement with the Company or any of its Affiliates.

      (d) Incentive Stock Option Limitation. To the extent that the aggregate
Fair Market Value (determined at the time of grant) of Common Stock with respect
to which Incentive Stock Options are exercisable for the first time by any
Participant during any calendar year under all plans of the Company and its
Affiliates exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

      (e) Withholding. To the extent provided by the terms of an Option
Agreement or Stock Purchase Agreement, the Participant may satisfy any federal,
state or local tax withholding obligation relating to the exercise of an Award
by any of the following means or by a combination of such means: (1) tendering a
cash payment; (2) authorizing the Company to withhold shares from the shares of
Common Stock otherwise issuable to the Participant as a result of the exercise
of the Award; or (3) delivering to the Company owned and unencumbered shares of
the capital stock of the Company.

      (f) Agreement Not to Compete. Any Option Agreement or Stock Purchase
Agreement may, but need not, provide that at any time that the Participant
serves as an Employee, Director or Consultant of the Company or any of its
Affiliates and for a period of one year after the termination such service for
any reason, the Participant may not directly or indirectly, individually or as a
consultant to, or employee, officer, director, stockholder, partner or other
owner or participant in any business entity, whether for profit or
not-for-profit, other than the Company or an Affiliate, engage in or assist any
other person to engage in any business in which the Company or its Affiliates
are engaging or in which the Company or its Affiliates plan to engage at the
time of such Participant's termination, including but not limited to the
provision of hospice related services, anywhere in the United States of America.
In the case of an Option subject to an Option Agreement that contains such an
agreement not to compete, if the Participant violates such agreement not to
compete, the Option shall terminate, and the shares covered by such Option shall
revert to and again become available for issuance under the Plan. In the case of
a Stock Purchase Right subject to a Stock Purchase Agreement that contains such
an agreement not to compete, the violation by the Participant of such agreement
not to compete shall (i) entitle the Company to immediately exercise the Right
of Repurchase if the Stock subject to such Stock Purchase Agreement has been
purchased prior to the time of such violation or (ii) result in the immediate
cancellation of the Stock Purchase Right if the Stock subject to such Stock
Purchase Agreement has not been purchased prior to the time of such violation.

12.   Adjustments Upon Changes in the Common Stock.

      (a) If any change is made in the Common Stock subject to the Plan, or
subject to any Award (through merger, consolidation, reorganization,

he or she shall have the right to exercise an Option to the extent that he or
she was otherwise entitled to exercise such Option on the date employment

at least 30 days from the date of termination, if termination was caused other
than by such California Participant's death or "permanent and total disability"
