                           CALIPER LIFE SCIENCES, INC.
                           1999 EQUITY INCENTIVE PLAN

                             STOCK OPTION AGREEMENT
                   (INCENTIVE AND NONSTATUTORY STOCK OPTIONS)

      Pursuant to your Stock Option Grant Notice ("Certificate") and this Stock
Option Agreement, Caliper Life Sciences, Inc. (the "Company") has granted you an
option under its 1999 Equity Incentive Plan (the "Plan") to purchase the number
of shares of the Company's Common Stock indicated in your Certificate at the
Grant Price indicated in your Certificate. Defined terms not explicitly defined
in this Stock Option Agreement but defined in the Plan shall have the same
definitions as in the Plan.

      The details of your option are as follows:

      1. VESTING. Subject to the limitations contained herein, your option will
vest as provided in your Certificate, provided that vesting will cease upon the
termination of your Continuous Service.

      2. NUMBER OF SHARES AND GRANT PRICE. The number of shares of Common Stock
subject to your option and your grant price per share referenced in your
Certificate may be adjusted from time to time for Capitalization Adjustments, as
provided in the Plan.

      3. EXERCISE PRIOR TO VESTING ("EARLY EXERCISE"). If permitted in your
Certificate (i.e., the "Exercise Schedule" indicates that "Early Exercise" of
your option is permitted) and subject to the provisions of your option, you may
elect at any time that is both (i) during the period of your Continuous Service
and (ii) during the term of your option, to exercise all or part of your option,
including the nonvested portion of your option; provided, however, that:

            (a) a partial exercise of your option shall be deemed to cover first
vested shares of Common Stock and then the earliest vesting installment of
unvested shares of Common Stock;

            (b) any shares of Common Stock so purchased from installments that
have not vested as of the date of exercise shall be subject to the purchase
option in favor of the Company as described in the Company's form of Early
Exercise Stock Purchase Agreement;

            (c) you shall enter into the Company's form of Early Exercise Stock
Purchase Agreement with a vesting schedule that will result in the same vesting
as if no early exercise had occurred; and

                                       1
<PAGE>

            (d) if your option is an incentive stock option, then, as provided
in the Plan, to the extent that the aggregate Fair Market Value (determined at
the time of grant) of the shares of Common Stock with respect to which your
option plus all other incentive stock options you hold are exercisable for the
first time by you during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s)
or portions thereof that exceed such limit (according to the order in which they
were granted) shall be treated as nonstatutory stock options.

      4. METHOD OF PAYMENT. Payment of the grant price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the
grant price in cash or by check or in any other manner PERMITTED BY YOUR
CERTIFICATE, which may include one or more of the following:

            (a) In the Company's sole discretion at the time your option is
exercised and provided that at the time of exercise the Common Stock is publicly
traded and quoted regularly in The Wall Street Journal, pursuant to a program
developed under Regulation T as promulgated by the Federal Reserve Board that,
prior to the issuance of Common Stock, results in either the receipt of cash (or
check) by the Company or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds.

            (b) Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery" for these purposes, in the sole discretion of the Company at the time
you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by
the Company. Notwithstanding the foregoing, you may not exercise your option by
tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of
the Company's stock.

      5. WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock.

      6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise of your option must also comply
with other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not
be in material compliance with such laws and regulations.

                                       2
<PAGE>

      7. TERM. The term of your option commences on the Grant Date and expires
upon the EARLIEST of the following:

            (a) three (3) months after the termination of your Continuous
Service for any reason other than your Disability or death, provided that if
during any part of such three- (3-) month period your option is not exercisable
solely because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

            (b) twelve (12) months after the termination of your Continuous
Service due to your Disability;

            (c) eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates;

            (d) the Expiration Date indicated in your Certificate; or

            (e) the day before the tenth (10th) anniversary of the Grant Date.

      If your option is an incentive stock option, note that, to obtain the
federal income tax advantages associated with an "incentive stock option," the
Code requires that at all times beginning on the Grant Date of your option and
ending on the day three (3) months before the date of your option's exercise,
you must be an employee of the Company or an Affiliate, except in the event of
your death or Disability. The Company has provided for extended exercisability
of your option under certain circumstances for your benefit but cannot guarantee
that your option will necessarily be treated as an "incentive stock option" if
you continue to provide services to the Company or an Affiliate as a Consultant
or Director after your employment terminates or if you otherwise exercise your
option more than three (3) months after the date your employment terminates.

      8. EXERCISE.

            (a) You may exercise the vested portion of your option (and the
unvested portion of your option if your Certificate so permits) during its term
by delivering a Notice of Exercise (in a form designated by the Company)
together with the grant price to the Secretary of the Company, or to such other
person as the Company may designate, during regular business hours, together
with such additional documents as the Company may then require.

            (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of (1) the exercise of
your option, (2) the lapse of any substantial risk of forfeiture to which the
shares of Common Stock are subject at the time of exercise, or (3) the
disposition of shares of Common Stock acquired upon such exercise.

                                       3
<PAGE>

            (c) If your option is an incentive stock option, by exercising your
option you agree that you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of your option that occurs within two (2) years after the
date of your option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of your option.

            (d) By exercising your option you agree that the Company (or a
representative of the underwriter(s)) may, in connection with the first
underwritten registration of the offering of any securities of the Company under
the Securities Act, require that you not sell, dispose of, transfer, make any
short sale of, grant any option for the purchase of, or enter into any hedging
or similar transaction with the same economic effect as a sale, any shares of
Common Stock or other securities of the Company held by you, for a period of
time specified by the underwriter(s) (not to exceed one hundred eighty (180)
days) following the effective date of the registration statement of the Company
filed under the Securities Act. You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company and/or the
underwriter(s) that are consistent with the foregoing or that are necessary to
give further effect thereto. In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to your shares of
Common Stock until the end of such period.

      9. TRANSFERABILITY. Your option is not transferable, except by will or by
the laws of descent and distribution, and is exercisable during your life only
by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

      10. RIGHT OF FIRST REFUSAL. Shares of Common Stock that you acquire upon
exercise of your option are subject to any right of first refusal that may be
described in the Company's bylaws in effect at such time the Company elects to
exercise its right. The Company's right of first refusal shall expire on the
Listing Date.

      11. RIGHT OF REPURCHASE. To the extent provided in the Company's bylaws as
amended from time to time, the Company shall have the right to repurchase all or
any part of the shares of Common Stock you acquire pursuant to the exercise of
your option.

      12. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective shareholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

      13. WITHHOLDING OBLIGATIONS.

            (a) At the time you exercise your option, in whole or in part, or at
any time thereafter as requested by the Company, you hereby authorize
withholding from payroll and any

                                       4
<PAGE>

other amounts payable to you, and otherwise agree to make adequate provision for
(including by means of a "cashless exercise" pursuant to a program developed
under Regulation T as promulgated by the Federal Reserve Board to the extent
permitted by the Company), any sums required to satisfy the federal, state,
local and foreign tax withholding obligations of the Company or an Affiliate, if
any, which arise in connection with your option.

            (b) Upon your request and subject to approval by the Company, in its
sole discretion, and compliance with any applicable conditions or restrictions
of law, the Company may withhold from fully vested shares of Common Stock
otherwise issuable to you upon the exercise of your option a number of whole
shares of Common Stock having a Fair Market Value, determined by the Company as
of the date of exercise, not in excess of the minimum amount of tax required to
be withheld by law. If the date of determination of any tax withholding
obligation is deferred to a date later than the date of exercise of your option,
share withholding pursuant to the preceding sentence shall not be permitted
unless you make a proper and timely election under Section 83(b) of the Code,
covering the aggregate number of shares of Common Stock acquired upon such
exercise with respect to which such determination is otherwise deferred, to
accelerate the determination of such tax withholding obligation to the date of
exercise of your option. Notwithstanding the filing of such election, shares of
Common Stock shall be withheld solely from fully vested shares of Common Stock
determined as of the date of exercise of your option that are otherwise issuable
to you upon such exercise. Any adverse consequences to you arising in connection
with such share withholding procedure shall be your sole responsibility.

            (c) You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied. Accordingly, you
may not be able to exercise your option when desired even though your option is
vested, and the Company shall have no obligation to issue a certificate for such
shares of Common Stock or release such shares of Common Stock from any escrow
provided for herein.

      14. NOTICES. Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

      15. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan. In
the event of any conflict between the provisions of your option and those of the
Plan, the provisions of the Plan shall control.

                                                                    EXHIBIT 10.7

                           CALIPER LIFE SCIENCES, INC.
                           1999 EQUITY INCENTIVE PLAN

                      RESTRICTED STOCK UNIT AWARD AGREEMENT

      Pursuant to the Restricted Stock Unit Grant ("CERTIFICATE") on the
SmithBarney Citigroup website and this Restricted Stock Unit Award Agreement
("AGREEMENT") (collectively, the "AWARD"), Caliper Life Sciences, Inc. (the
"COMPANY") has awarded you a right to receive a delayed issuance stock bonus (a
"RESTRICTED STOCK UNIT") pursuant to Article 7 of the Company's 1999 Equity
Incentive Plan (the "PLAN") for the number of Restricted Stock Units as
indicated in the Certificate. Defined terms not explicitly defined in this
Agreement but defined in the Plan shall have the same definitions as in the
Plan. Subject to adjustment and the terms and conditions as provided herein and
in the Plan, each Restricted Stock Unit shall represent the right to receive a
stock bonus of one (1) share of Common Stock.

      The details of your Award, in addition to those set forth in the
Certificate, are as follows:

      1. NUMBER OF RESTRICTED STOCK UNITS AND SHARES OF COMMON STOCK. The number
of Restricted Stock Units in your Award is set forth in the Certificate.

            (a) The number of Restricted Stock Units subject to your Award
and/or the number of shares of Common Stock deliverable with respect to such
Restricted Stock Units may be adjusted from time to time for capitalization
adjustments as described in Article 11 of the Plan. You will receive no benefit
or adjustment to your Award with respect to any cash dividend or other
distribution that does not result in a capitalization adjustment pursuant to
Section 11(a) of the Plan; provided, however, that this sentence shall not apply
with respect to any shares of Company Common Stock that are delivered to you in
connection with your Award after such shares have been delivered to you.

            (b) Any additional Restricted Stock Units, shares of Common Stock,
cash or other property that becomes subject to the Award pursuant to this
Section 1 shall be subject, in a manner determined by the Board, to the same
forfeiture restrictions, restrictions on transferability and time and manner of
delivery as apply to the other Restricted Stock Units and Common Stock covered
by your Award.

            (c) Notwithstanding the provisions of this Section 1, no fractional
Restricted Stock Units or rights for fractional shares of Common Stock shall be
created pursuant to this Section 1. The Board shall, in its discretion,
determine an equivalent benefit for any fractional Restricted Stock Units or
fractional shares that might be created by the adjustments referred to in this
Section 1.

      2. VESTING. The Restricted Stock Units shall vest, if at all, as provided
in the Certificate and the Plan.

<PAGE>

      3. DELIVERY OF SHARES OF COMMON STOCK.

            (a) Subject to the provisions of this Agreement and the Plan, in the
event one or more Restricted Stock Units vests, the Company shall deliver to you
one (1) share of Common Stock for each Restricted Stock Unit that vests. The
delivery to you of the appropriate number of shares of Common Stock shall be
made as soon as practical after the applicable vesting date. The form of such
delivery (e.g., a stock certificate or electronic entry evidencing such shares)
shall be determined by the Company.

            (b) Notwithstanding the provisions of Section 3(a), if delivery of
shares of Common Stock would occur at a time at which you would not be permitted
to sell such shares of Common Stock under a Company policy governing trading by
Company officers, directors and/or employees (a "TRADING POLICY"), such delivery
of Common Stock shall be deferred until the first date upon which such shares of
Common Stock may be sold not in violation of any Trading Policy.

            (c) Notwithstanding the provisions of this Section 3, the Company
may, at any time in its sole discretion, issue to you the Common Stock that
would be delivered to you upon the vesting of a Restricted Stock Unit. In
addition, if the Company elects to deliver to you Common Stock prior to the date
the applicable Restricted Stock Unit would vest, the Company may impose on the
Common Stock so delivered such vesting or other forfeiture provisions not
inconsistent with the Plan that are reasonably equivalent to the vesting
provisions to which the Restricted Stock Unit was subject. In the event that any
Common Stock would be subject to vesting or other forfeiture provisions, you
agree to execute such documentation as may be reasonable required by the Company
to effectuate such delivery and the associated vesting or forfeiture provisions.

      4. PAYMENT BY YOU. This Award was granted in consideration of your past
services to the Company. Subject to Section 10 below, except as otherwise
provided in the Certificate, you will not be required to make any payment to the
Company (other than your past and future services with the Company) with respect
to your receipt of the Award, vesting of the Restricted Stock Units or the
delivery of the shares of Common Stock underlying the Restricted Stock Units.

      5. SECURITIES LAW COMPLIANCE. You may not be issued any Common Stock under
your Award unless the shares of Common Stock are either (i) then registered
under the Securities Act of 1933, as amended (the "SECURITIES ACT") or (ii) the
Company has determined that such issuance would be exempt from the registration
requirements of the Securities Act. Your Award must also comply with other
applicable laws and regulations governing the Award, and you shall not receive
such Common Stock if the Company determines that such receipt would not be in
material compliance with such laws and regulations.

      6. RESTRICTIVE LEGENDS. The Common Stock issued under your Award shall be
endorsed with appropriate legends, if any, determined by the Company.

      7. TRANSFER RESTRICTIONS. Prior to the time that shares of Common Stock
have been delivered to you, you may not transfer, pledge, sell or otherwise
dispose of the shares in

                                       2.
<PAGE>

respect of your Award. For example, you may not use shares that may be issued in
respect of your Restricted Stock Units as security for a loan, nor may you
transfer, pledge, sell or otherwise dispose of such shares. This restriction on
transfer will lapse upon delivery to you of shares in respect of your vested
Restricted Stock Units. Your Award is not transferable, except by will or by the
laws of descent and distribution. Notwithstanding the foregoing, by delivering
written notice to the Company, in a form satisfactory to the Company, you may
designate a third party who, in the event of your death, shall thereafter be
entitled to receive any distribution of Common Stock pursuant to this Agreement.

      8. AWARD NOT A SERVICE CONTRACT. Your Award is not an employment or
service contract, and nothing in your Award shall be deemed to create in any way
whatsoever any obligation on your part to continue in the service of the Company
or an Affiliate thereof, or on the part of the Company or an Affiliate thereof
to continue such service. In addition, nothing in your Award shall obligate the
Company or an Affiliate thereof, their respective stockholders, boards of
directors or employees to continue any relationship that you might have as an
Employee or Consultant of the Company or an Affiliate thereof.

      9. UNSECURED OBLIGATION. Your Award is unfunded, and even as to any
Restricted Stock Units which vest, you shall be considered an unsecured creditor
of the Company with respect to the Company's obligation, if any, to issue Common
Stock pursuant to this Agreement. You shall not have voting or any other rights
as a stockholder of the Company with respect to the Common Stock acquired
pursuant to this Agreement until such Common Stock is issued to you pursuant to
Section 2 of this Agreement. Upon such issuance, you will obtain full voting and
other rights as a stockholder of the Company with respect to the Common Stock so
issued. Nothing contained in this Agreement, and no action taken pursuant to its
provisions, shall create or be construed to create a trust of any kind or a
fiduciary relationship between you and the Company or any other person.

      10. WITHHOLDING OBLIGATIONS.

            (a) On or before the time you receive a distribution of Common Stock
pursuant to your Award, or at any time thereafter as requested by the Company,
you hereby authorize any required withholding from, at the Company's election,
the Common Stock issuable to you, payroll and any other amounts payable to you
and otherwise agree to make adequate provision for any sums required to satisfy
the federal, state, local and foreign tax withholding obligations of the Company
or any Affiliate thereof which arise in connection with your Award.

            (b) Unless the tax withholding obligations of the Company and/or any
Affiliate thereof are satisfied, the Company shall have no obligation to deliver
to you any Common Stock.

            (c) In the event the Company's obligation to withhold arises prior
to the delivery to you of Common Stock or it is determined after the delivery of
Common Stock to you that the amount of the Company's withholding obligation was
greater than the amount withheld by the Company, you agree to indemnify and hold
the Company harmless from any failure by the Company to withhold the proper
amount.

                                       3.
<PAGE>

      11. NOTICES. Any notices provided for in your Award or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by the Company to you, five (5) days after deposit in
the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company.

      12. HEADINGS. The headings of the Sections in this Agreement are inserted
for convenience only and shall not be deemed to constitute a part of this
Agreement or to affect the meaning of this Agreement.

      13. AMENDMENT. This Agreement may be amended only by a writing executed by
the Company and you which specifically states that it is amending this
Agreement. Notwithstanding the foregoing, this Agreement may be amended solely
by the Company by a writing which specifically states that it is amending this
Agreement, so long as a copy of such amendment is delivered to you, and provided
that no such amendment adversely affecting your rights hereunder may be made
without your written consent. Without limiting the foregoing, the Company
reserves the right to change, by written notice to you, the provisions of this
Agreement in any way it may deem necessary or advisable to carry out the purpose
of the grant as a result of any change in applicable laws or regulations or any
future law, regulation, ruling, or judicial decision, provided that any such
change shall be applicable only to rights relating to that portion of the Award
which is then subject to restrictions as provided herein.

      14. MISCELLANEOUS.

            (a) The rights and obligations of the Company with respect to your
Award shall be transferable by the Company to any one or more persons or
entities, and all covenants and agreements hereunder shall inure to the benefit
of, and be enforceable by the Company's successors and assigns.

            (b) You agree upon request to execute any further documents or
instruments necessary or desirable in the sole determination of the Company to
carry out the purposes or intent of your Award.

            (c) You acknowledge and agree that you have reviewed your Award in
its entirety, have had an opportunity to obtain the advice of counsel prior to
executing and accepting your Award and fully understand all provisions of your
Award.

            (d) This Agreement shall be subject to all applicable laws, rules,
and regulations, and to such approvals by any governmental agencies or national
securities exchanges as may be required.

            (e) All obligations of the Company under the Plan and this Agreement
shall be binding on any successor to the Company, whether the existence of such
successor is the result of a direct or indirect purchase, merger, consolidation,
or otherwise, of all or substantially all of the business and/or assets of the
Company.

      15. GOVERNING PLAN DOCUMENT. Your Award is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your Award, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be

                                       4.
<PAGE>

promulgated and adopted pursuant to the Plan. In the event of any conflict
between the provisions of your Award and those of the Plan, the provisions of
the Plan shall control; provided, however, that Section 3 of this Agreement
shall govern the timing of any distribution of Common Stock under your Award.
The Board shall have the power to interpret the Plan and this Agreement and to
adopt such rules for the administration, interpretation, and application of the
Plan as are consistent therewith and to interpret or revoke any such rules. All
actions taken and all interpretations and determinations made by the Board shall
be final and binding upon you, the Company, and all other interested persons. No
member of the Board shall be personally liable for any action, determination, or
interpretation made in good faith with respect to the Plan or this Agreement.

      16. EFFECT ON OTHER EMPLOYEE BENEFIT PLANS. The value of the Award subject
to this Agreement shall not be included as compensation, earnings, salaries, or
other similar terms used when calculating benefits under any employee benefit
plan (other than the Plan) sponsored by the Company or any Subsidiary except as
such plan otherwise expressly provides. The Company expressly reserves its
rights to amend, modify, or terminate any or all of the employee benefit plans
of the Company or any Subsidiary.

      17. CHOICE OF LAW. The interpretation, performance and enforcement of this
Agreement shall be governed by the law of the state of California without regard
to such state's conflicts of laws rules.

      18. SEVERABILITY. If all or any part of this Agreement or the Plan is
declared by any court or governmental authority to be unlawful or invalid, such
unlawfulness or invalidity shall not invalidate any portion of this Agreement or
the Plan not declared to be unlawful or invalid. Any Section of this Agreement
(or part of such a Section) so declared to be unlawful or invalid shall, if
possible, be construed in a manner which will give effect to the terms of such
Section or part of a Section to the fullest extent possible while remaining
lawful and valid.

                                    * * * * *
