Dear
Bob, 

        On
behalf of ePocrates, Inc. (the "Company"), I am pleased to offer you the position of Vice President of Engineering and Chief Technical Officer. 

        The
terms and conditions of your new position with the Company are as set forth below: 

        1.    Position.    

        a.     You
will become Vice President of Engineering and Chief Technical Officer, for the Company. You will report directly to the President and Chief Executive Officer. 

        b.     You
agree to the best of your ability and experience that you will at all times conscientiously perform all of the duties and obligations required of you to the
reasonable satisfaction of the Company. During the term of your employment, you further agree that you will devote all of your business time and attention to the business of the Company, the Company
will be entitled to all of the benefits and profits arising from or incident to all such work services and advice, you will not render commercial or professional services of any nature to any person
or organization, whether or not for compensation, without the prior written consent of the Company's Board of Directors, and you will not directly or indirectly engage or participate in any business
that is competitive in any manner with the business of the Company. Nothing in this letter agreement will prevent you from accepting speaking or presentation engagements in exchange for honoraria or
from serving on boards of charitable organizations, or from owning no more than one percent (1%) of the outstanding equity securities of a corporation whose stock is listed on a national stock
exchange. 

        2.    Start Date.    Subject to fulfillment of any conditions imposed by this letter
agreement, you will commence this new position with the Company on June 1, 2002. 

        3.    Proof of Right to Work.    For purposes of federal immigration law, you will be required
to provide to the Company documentary evidence of your identity and eligibility for employment in the United States. 

        4.    Compensation    

        a.    Base Salary.    Your salary will be payable in semi monthly installments of $7083.34
pursuant to the Company's regular payroll policy. This equates to an annual salary of $170,000. 

        b.    MBO Bonus.    You will be eligible to participate in an Annual MBO Bonus Plan that will
pay up $50,000 based upon successful completion of the objectives. The President and Chief Executive Officer will work with you to establish your objectives. The objectives will be provided to you
within your first thirty days with the Company. Your bonus will be calculated and paid at your one-year anniversary. 

        c.    Annual Review.    Your base salary will be reviewed annually as part of the Company's
normal salary review process. 

        d.    Health Insurance.    At your request, we will not enroll you in our standard Health
plan. In lieu of this coverage, we are increasing your semi monthly compensation by $375. 

        5.    Stock Option.    In connection with the commencement of your employment, the Company
will recommend that the Board of Directors grant you an option to purchase 120,000 shares of the Company's Common Stock ("Shares") with an exercise
price equal to the fair market value on the date 

of
the grant. These option shares will vest according to the following schedule: 1/4th of the total shares shall vest on the annual anniversary of your commencement date (June 1, 2003)
and 1/48th of the shares shall vest monthly thereafter over the next three years. Vesting will, of course, depend on your continued employment with the Company. The option will be an incentive
stock option to the maximum extent allowed by the tax code and will be subject to the terms of the Company's Stock Plan and the Stock Option Agreement between you and the Company. 

        6.    Benefits.    You have opted to not participate in our standard health plan so you can
continue under your current plan. We will be providing our standard dental and vision plan. Employees are eligible for 10 days of vacation in their first full calendar year of employ and
15 days in each calendar year thereafter. Further details about benefits are available for your review. ePocrates may modify compensation and benefits from time to time, as it deems necessary. 

        7.    Confidential Information and Invention Assignment Agreement.    Your acceptance of this
offer and commencement of employment with the Company is contingent upon the execution, and delivery to an officer of the Company, of the Company's Confidential Information and Invention Assignment
Agreement (the "Confidentiality Agreement"), a copy of which is enclosed for your review and execution, prior to or on your Start Date. 

        8.    Confidentiality of Terms.    You agree to follow the Company's strict policy that
employees must not disclose, either directly or indirectly, any information, including any of the terms of this agreement, regarding salary, bonuses, or stock purchase or option allocations to any
person, including other employees of the Company; provided, however, that you may discuss such terms with members of your immediate family and any legal, tax or accounting specialists who provide you
with individual legal, tax or accounting advice. 

        9.    At-Will Employment.    Your employment with the Company will be on an "at
will" basis, meaning that either you or the Company may terminate your employment at any time for any reason or no reason, without further obligation or liability. 

        10.    Severance.    If the Company conducts a layoff of 75% or more of its
then-current employees, and if you are selected to be included in such a layoff, you will receive continuation of your base salary, less standard deductions and withholdings, for a period
of two (2) months after your termination date. This severance amount will be in lieu of any severance benefits offered to other laid-off employees. In order to receive this
severance payment, you must sign a general release of all claims in a format acceptable to the Company and allow this release to become effective. 

        We
are all delighted to be able to extend you this offer and look forward to working with you. To indicate your acceptance of the Company's offer, please sign and date this letter in the
space provided below and return it to me, along with a signed and dated copy of the Confidentiality Agreement. This letter, together with the Confidentiality Agreement, set forth the terms of your
employment with the Company and supersede any prior representations or agreements, whether written or oral. This letter may not be modified or amended except by a written agreement, signed by the
Company and by you. 

        This
offer is contingent on the successful completion of a background check, which we will initiate upon receipt of your application. 

This
offer is valid until May 17, 2002. 

	Very truly yours,

ePocrates, Inc.

Re: Modification of Employment Terms  

Dear
Robert: 

As
we have discussed, this letter agreement confirms an amendment (the "Amendment") to the terms of your employment offer letter with
Epocrates, Inc. (the "Company") dated May 15, 2002 (the "Offer Letter"). The Amendment
will become effective only as of the effective date of the initial public offering of the Company's common stock (the "IPO"), and if the IPO does not
occur, this Amendment will not become effective. For the purposes of the Offer Letter and this Amendment, we agree that the IPO will not qualify as a Change of Control (defined in Section 11). 

The
Amendment is as follows: 

        1.     Section 10 of the Offer Letter will be superseded in its entirety and replaced with the following: 

        10.    Severance Benefits Not In Connection With A Change of
Control.    If, at any time other than during the twelve (12) months following the consummation of a Change of Control (as defined in Section 11
herein), the Company or any successor entity terminates your employment without Cause (as defined
herein), and if you first sign, date, and deliver to the Company a separation agreement that includes a general release of all known and unknown claims in the form provided to you by the Company and
allow this separation agreement and release to become effective, then you will receive the following as your sole severance benefits (the "Severance
Benefits"): (i) severance pay equal to six (6) months of your base salary in effect as of the termination date, less required deductions and withholdings, paid in
the form of salary continuation on the Company's standard payroll dates (beginning with the first payroll date following the effective date of the required separation agreement); and
(ii) provided that you timely elect continued group health insurance coverage through federal COBRA law or comparable state law (collectively,
"COBRA"), the Company will pay your COBRA premiums sufficient to continue your group health insurance coverage at the same level in effect as of your
termination date for six (6) months after your termination or until you become eligible for group health insurance coverage through a new employer, whichever occurs first. For purposes of this
letter agreement, "Cause" means any of the following conduct by you: (i) embezzlement, misappropriation of corporate funds, or other material
acts of dishonesty; (ii) the conviction, plea of guilty, or nolo contendere to any felony (not involving the operation of a motor vehicle), or of any misdemeanor involving moral turpitude;
(iii) engagement in any activity that you know or should know could materially harm the business or reputation of the Company, provided that this subsection (iii) shall not apply to any
activity done in a good faith belief by you that the action taken or omission was in the best interest of the Company; (iv) material violation of any statutory, contractual, or common law duty
or obligation owed by you to the Company, including, without limitation, the duty of loyalty which causes demonstrable injury to the Company; (v) material breach of the Confidentiality
Agreement; or (vi) repeated failure, in the reasonable judgment of the Board, to substantially perform your assigned duties or responsibilities after written notice from the Board describing
the failure(s) in reasonable detail and your failure to cure such failure(s) within thirty (30) days of receiving such written notice, provided that written notice only must be provided if the
failure(s) are capable of cure. 

1

 

        2.     The following will become Section 11 of the Offer Letter. 

        11.    Change of Control Severance Benefits    In the event that:
(i) the Company consummates a change of control transaction, whereby fifty percent (50%) or more of the voting stock of the Company changes ownership pursuant to such transaction (a
"Change of Control"); and (ii) within twelve (12) months after the consummation of a Change of Control, your employment with the Company
is either (a) terminated by the Company or successor entity without Cause (as defined in Section 10 herein), or (b) terminated by you for Good Reason (as defined in and in
accordance with the paragraph below); and (iii) you sign, date, and deliver to the Company a separation agreement that includes a general release of all known and unknown claims in the form
provided to you by the Company and allow this separation agreement and release to become effective; then you will receive the following as your sole severance benefits (the
"Change of Control Severance Benefits"): (a) severance pay equal to nine (9) months of your base salary in effect as of the termination
date, less required deductions and withholdings, paid in the form of salary continuation on the Company's standard payroll dates (beginning with the first payroll date following the effective date of
the required separation agreement); (b) provided that you timely elect continued group health insurance coverage through COBRA, the Company will pay your COBRA premiums sufficient to continue
your group health insurance coverage at the same level in effect as of your termination date for nine (9) months after your termination or until you become eligible for group
health insurance coverage through a new employer, whichever occurs first; and (c) notwithstanding the vesting schedule set forth in Section 5, any unvested shares subject to any option
grants held by you as of the employment termination date (including, but not limited to, any unvested Shares subject to the option grant discussed in Section 5) will become vested and
exercisable, effective as of the employment termination date. 

        For
purposes of this Section 11, "Good Reason" shall mean one or more of the following conditions that resulted from the
consummation of the Change of Control without your written consent: (i) a relocation of your assigned office more than thirty-five (35) miles from its location immediately
prior to the Change of Control; (ii) a material decrease in your base salary (except for salary decreases generally applicable to the Company's other executive employees); or (iii) a
material reduction in the scope of your duties or responsibilities from your duties and responsibilities in effect immediately prior to the Change of Control. Notwithstanding the foregoing, you shall
not be deemed to have terminated your employment for "Good Reason" unless (i) such termination occurs within ninety (90) days following the initial existence of one or more of the
conditions that constitute Good Reason (as defined herein), and (ii) you provide written notice to the Company (or any successor entity) of the existence of the Good Reason condition within
thirty (30) days following the initial existence of the condition, and the Company (or its successor entity) shall have a period of thirty (30) days following such notice to cure the
condition. If the condition is cured within such time period, such condition shall not constitute a condition for which you may terminate your employment for Good Reason. 

        3.     The following will become Section 12 of the Offer Letter. 

        12.    Parachute Payments.    In the event that the benefits provided
for in this letter agreement or otherwise payable to you ("Payment") would constitute "parachute payments" within the meaning of Section 280G of
the Internal Revenue Code of 1986, as amended (the "Code") and, but for this sentence, would be subject to the excise tax imposed by Section 4999
of the Code (the "Excise Tax"), then such Payment shall be equal to the Reduced Amount. The "Reduced
Amount" shall be either (i) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax, or (ii) the largest
portion, up to and including the total, of the Payment, whichever of the foregoing amounts, after taking into account all applicable federal, state and local employment taxes, income taxes and the
Excise Tax (all computed at the highest applicable marginal rate), results in the receipt by you, on an after-tax basis, of the greater 

2

 

amount
of the Payment, notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. Unless the Company and you otherwise agree in writing, the determination of your Excise
Tax liability shall be made in writing by the accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change of Control (the
"Accountants"). If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the
Change of Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. For purposes of making the calculations required by this
Section 12, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of
Sections 280G and 4999 of the Code. Any good faith determinations of the Accountants made hereunder shall be final, binding, and conclusive upon the Company and you. The Company and you shall
furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations contemplated by this Section 12. To the extent that any elimination in or reduction of payments or benefits is made under
this Section 12, the determination as to the order in which payments and benefits shall be reduced shall be made by you (subject, however, to the Company's approval if made on or after the date
on which the event that triggers the payments or benefits occurs). 

        4.     The following will become Section 13 of the Offer Letter. 

        13.    Deferred Compensation.    Severance payments made pursuant to
Section 10 or Section 11, to the extent of payments made from the date of your termination through March 15 of the calendar year following your termination, are intended to
constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations and thus payable pursuant to the "short-term deferral" rule set forth in
Section 1.409A-1(b)(4) of the Treasury Regulations. To the extent such payments are made following said March 15, they are intended to constitute separate payments for
purposes of Section 1.409A-2(b)(2) of the Treasury Regulations made upon an involuntary termination from service and payable pursuant to
Section 1.409A-1(b)(9)(iii) of the Treasury Regulations, to the maximum extent permitted by such provision, with any excess amount being regarded as subject to the distribution
requirements of Section 409A(a)(2)(A) of the Code, including, without limitation, the requirement of Section 409A(a)(2)(B)(i) of the Code that payment be delayed until six
(6) months after separation from service if you are a "specified employee" within the meaning of Section 409A(a)(2)(B)(i) of the Code at the time of such separation from service. 

Except
as modified herein, all other terms of the Offer Letter shall remain in full force and effect. 

This
Amendment, together with the Offer Letter, constitutes the entire agreement between you and the Company regarding the terms of your employment, effective as of the first business day of the IPO.
It supersedes any prior statements, representations or promises made to you concerning the subjects contained in this letter agreement and the Offer Letter, and only can be modified in a writing
signed by you and a duly authorized director or officer of Epocrates. 

Please
sign below if these terms are acceptable to you.

Mr. Kirk
Loevner 

Dear
Kirk, 

        On
behalf of ePocrates, Inc. ("ePocrates" or the "Company"), I am pleased to offer you the position of President and Chief Executive Officer ("CEO") under the terms and conditions
stated herein. 

        1.     Position.

	a.
	Title, Reporting Relationship, Office Location, Board Service.    You will be the Company's full-time President
and CEO. You will report directly to the Company's Board of Directors (the "Board"), and work out of the Company's headquarters currently located in San
Mateo, California. The Company agrees to nominate you for a director position on the Board. You hereby agree to resign as a member of the Board, if requested by the Company, effective on the date on
which your employment with the Company terminates or at such earlier date as specified by the Company.

	b.
	Duties.    As President and CEO, you will have the duties and responsibilities as set forth in the Bylaws of the Company and
as assigned to you by the Company's Board of Directors.

	c.
	Performance, Outside Activities.    You agree to the best of your ability and experience that you will at all times
conscientiously perform all of the duties and obligations required of you to the reasonable satisfaction of the Board. (However, the failure to perform to such reasonable satisfaction shall not alone
be a ground for "Cause" as defined herein). During the term of your employment, you further agree that you will devote all of your business time and attention to the business of the Company, the
Company will be entitled to all of the benefits and profits arising from or incident to all such work services and advice, you will not render commercial or professional services of any nature to any
person or organization, whether or not for compensation, without the prior written consent of the Board, and you will not directly or indirectly engage or participate in any activity or business that
is competitive in any manner with the business of the Company. Nothing in this letter agreement will prevent you from accepting speaking or presentation engagements in exchange for honoraria or from
serving on boards of charitable organizations, or from owning no more than one percent (1%) of the outstanding equity securities of a corporation whose stock is listed on a national stock exchange. 

        2.     Start Date.    Subject to fulfillment of any conditions imposed by this letter agreement, you will commence this
new position with the Company on June 28, 2004 (the "Start Date"). 

        3.     Proof of Right to Work.    For purposes of federal immigration law, you will be required to provide to the
Company documentary evidence of your identity and eligibility for employment in the United States. 

1800 Gateway Drive, Suite 300, San Mateo, CA 94404    Tel: 650-227-1700 Fax:
650-227-2770            www.epocrates.com

        4.     Compensation.

	a.
	Base Salary.    Your initial monthly base salary will be twenty thousand, eight hundred thirty-three dollars and thirty-three
cents ($20,833.33), less payroll deductions and required withholdings, and payable in semi-monthly installments on the Company's regular payroll schedule. This equates to an annual base
salary of two hundred fifty thousand dollars ($250,000).

	b.
	Incentive Compensation.    You will be eligible to receive an annual bonus of up to seventy-five thousand dollars
($75,000). Such bonuses shall be based upon achievement of milestones that have been set for you by the Company's Board of Directors (or the Compensation Committee). You shall be eligible to receive a
bonus of up to $37,500 for your efforts during 2004 based on achievement of milestones that have been set for you by the Company's Board of Directors (or the Compensation Committee). Such bonuses, if
any, are awarded at the sole discretion of the Board, based on its assessment of your performance and the Company's performance against these milestones. You must remain employed through the end of
the year in order to earn and be eligible to receive a bonus, and no pro rata or partial bonuses will be provided. No bonuses are earned until the Board confirms such bonuses in writing. The Board
shall have the sole discretion to change or eliminate the annual bonus program at any time, and to determine the amount of bonus earned by you.

	c.
	Annual Review.    Your base salary and incentive compensation shall be reviewed annually by the Board on or before your Start
Date, although the Board is not obligated to increase your then-current salary or incentive compensation. The Board shall not reduce your then current salary unless such reduction is part
of a Company-wide reduction in which the salary of all other executive officers of the Company are reduced pro-rata.

	d.
	Relocation Assistance.    To assist with your relocation to the San Francisco Bay Area, the Company will reimburse your
out-of-pocket costs to move your household goods and other personal property to the Bay Area, up to a maximum of thirty thousand dollars ($30,000) in the aggregate. The Company
will also provide you with a temporary living allowance of three thousand dollars ($3,000) per month to be used to cover your temporary housing costs in the Bay Area, such allowance to be provided
during your first six (6) months of employment or until you move into a permanent residence in the Bay Area, whichever occurs first. In addition, to further assist you in your relocation, the
Company agrees to reimburse your out-of pocket costs for up to ten (10) round trip coach class airfare tickets to/from your current residence and the Bay Area, such tickets to be
used by either you or your spouse. Finally, the Company agrees to provide you an additional relocation allowance of up to fifty thousand dollars ($50,000) to defray your
out-of-pocket closing costs associated with the sale of your residence in Connecticut. In order to receive the relocation allowance, you must provide documentation, reasonably
satisfactory to the Company, of such selling costs. The relocation assistance provided to you will be subject to deductions and withholdings consistent with applicable law. 

        5.     Stock Option. 

	a.
	Stock Option Grant.    In connection with the commencement of your employment, the Company will recommend that the Board of
Directors (the "Board") grant you an option to purchase one million, one hundred eighty-two thousand, two hundred seven (1,182,207) shares
of the Company's Common Stock ("Shares") under the Company's 1999 Stock Option Plan (the "Plan") with a
per share exercise price equal to twenty-five cents ($0.25) (the "Option"). Such grant represents approximately five percent (5%) of the
fully diluted outstanding capitalization of the Company, including all stock, stock warrants or securities convertible into common stock, and all stock reserved for option grants (whether such options
are issued or not) as of the date of this letter. (Herein referred to as "Fully Diluted Stock".) The Option will be subject to the terms of the Plan and
your 

individual
Stock Option Agreement with the Company, which shall include the following vesting schedule for the Shares: 1/4th of the Shares shall vest on the first annual anniversary of the
Start Date, and 1/48th of the Shares shall vest monthly thereafter over the next three years. Vesting will, of course, depend on your continued employment with the Company. The Option will be
an incentive stock option to the maximum extent allowed by the tax code. 

	b.
	Acceleration.    Notwithstanding the foregoing vesting schedule, the Shares (and the shares subject to any future option
grants) will be subject to the Acceleration (defined below) if the Company consummates a Change of Control (as defined herein) and your employment is either: (i) terminated by the Company or a
successor entity without Cause (as defined in Paragraph 12(b) of this letter) within twelve (12) months after a Change of Control; or (ii) terminated by you within twelve
(12) months after a Change of Control for Good Reason (as defined herein). In order to be eligible to receive the Acceleration, you must first sign, date, and deliver to the Company a general
release of all known and unknown claims in the form provided to you by the Company and allow it to become effective.

	c.
	Definitions.

	i.
	For
purposes of this letter, the "Acceleration" shall mean additional vesting of the Shares (and the shares subject to any future option
grants) such that all unvested Shares subject to the Option (and the shares subject to any future option grants) shall become fully vested and immediately exercisable, and all options, including
future option grants, shall be exercisable for one (1) year from the date of termination of your employment.

	ii.
	For
purposes of this letter, "Change of Control" shall mean the occurrence of any of the following events: (1) any "Person" (as
such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the "Beneficial Owner" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the Company's then outstanding voting securities; or (2) a
merger, reverse merger or other consolidation of the Company, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the total voting power represented by
the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or (3) the liquidation of the Company or the sale or disposition by the
Company of all or substantially all of the Company's assets or its business. A Change of Control shall expressly not include: (1) any consolidation or merger effected exclusively to change the
domicile of the Company, or (2) any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received solely by the Company or indebtedness of
the Company only is cancelled or converted or a combination thereof.

	iii.
	For
purposes of this letter, "Good Reason" following a Change of Control shall mean: (1) a relocation of your assigned office
more than thirty-five (35) miles from its location immediately prior to the Change of Control; or (2) a material decrease in your base salary or Company benefits (except for
salary decreases or benefit changes generally applicable to the Company's other executive employees); or (3) the failure of any successor-in-interest to assume all of
the obligations of the Company under this letter agreement; or (4) any material breach of this letter agreement by the Company or its successor; or (5) a material reduction in the scope
of your duties or responsibilities from your duties and responsibilities in effect immediately prior to 

the
Change of Control, provided, however, that a necessary change in your authority, duties, or responsibilities solely by virtue of the Company being acquired and made part of a larger entity (as,
for example, when you remain the equivalent of Chief Executive Officer and President of the Company's business operations that are a subsidiary or division of the acquirer following a Change of
Control) shall not by itself constitute a "Good Reason". Your employment shall not be deemed to be terminated for "Good Reason" unless written notice stating the basis for the termination is provided
to the Company by you and the Company is given fifteen (15) days after receipt of such notice to cure the neglect or conduct that is the basis of such claim (but only with respect to curable
actions or failures to act). 

	iv.
	For
the purposes of this letter, "Good Reason", absent a Change of Control, shall mean: (1) a material reduction in the scope of your duties or responsibilities from your
duties and responsibilities granted to you by this letter agreement; or (2) the removal of your title as President or CEO or changes in the requirement that you report directly to the Board; or
(3) any material breach of this letter agreement by the Company.

	v.
	Death
or disability. Termination of your employment by death or disability shall not be considered a Termination without Cause or a Termination for Good Reason for purposes of
Paragraphs 5 and 12 herein. However, if at the time of your death or disability you had the right to terminate with Good Reason, such right may be asserted by your estate or heirs. 

        6.     Option to Purchase Series C Preferred Stock.    You will be provided the opportunity to purchase one
percent (1%) of the Company's Fully-Diluted Series C Preferred Stock or up to two hundred thirty-six thousand, four hundred forty-one (236,441) shares of ePocrates
Series C Preferred Stock (the "Series C Shares"), at a purchase price of $1.5926 per share, pursuant to the terms and conditions of that
certain Series C Preferred Stock Purchase Agreement, dated as of July 1, 2002, as amended. As a precondition of your purchase of the Series C Shares, you must become a party to
the following agreements: (a) that certain Amended and Restated Investor Rights Agreement, dated as of July 1, 2002; and (b) that certain Amended and Restated Voting Agreement,

approved by the Board and signed by you and by an officer of the Company. 

        12.   Severance. 

	a.
	Severance Benefits.    In the event that the Company or any successor terminates your employment without Cause, or if you
resign for Good Reason (as that term is defined in Section 5(c)(iii) herein (if your resignation occurs after a Change in Control); or Section 5(c)(iv) (if your resignation does not
occur after a Change of Control); and, in either event, if you first sign, date, and deliver to the Company a separation agreement that includes a general release of all known and unknown claims in
the form provided to you by the Company, and allow this separation agreement to become effective, then you will receive, as your sole severance benefits: (i) severance pay equal to twelve

(beginning with the first payroll date following the effective date of the required separation agreement); (ii) provided that you timely elect continued group health insurance coverage through

Option equal to the lesser of either (A) the number of unvested Shares that would have vested if your employment had continued for twelve (12) months after your termination date, or

following conduct by you: (i) embezzlement, misappropriation of corporate funds, or other material acts of dishonesty; (ii) the conviction, plea of guilty, or nolo contendere to any
felony (not involving the operation of a motor vehicle), or of any misdemeanor involving moral turpitude; (iii) engagement in any activity that you know or should know could materially harm the

interest of the Company; (iv) material violation of any statutory, contractual, or common law duty or obligation owed by you to the Company, including, without limitation, the duty of loyalty
which causes demonstrable injury to the Company; (vi) material breach of the Confidentiality Agreement; or (vii) repeated failure, in the reasonable judgment of the Board, to
substantially perform your assigned duties or responsibilities after written notice from the Board describing the failure(s) in reasonable 

detail
and your failure to cure such failure(s) within thirty (30) days of receiving such written notice, provided that written notice only must be provided if the failure(s) are capable of
cure. 

        13.   Parachute Payments.    In the event that the benefits provided for in this letter agreement or otherwise
payable to you constitute "parachute payments" within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code") and will be subject to the excise tax imposed by
Section 4999 of the Code (the "Excise Tax"), then your benefits under this Agreement shall be either (i) delivered in full, or (ii) delivered as to a lesser extent, whichever of
the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by you on an after-tax basis, of the greatest
amount of benefits, notwithstanding that all or some portion of such benefits may be subject to the Excise Tax. Unless the Company and you otherwise agree in writing, the determination of your Excise
Tax liability shall be made in writing by the accounting firm engaged by the Company for general audit purposes (the "Accountants"). For purposes of making the calculations required by this
Section 13, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of
Sections 280G and 4999 of the Code. The Company and you shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a
determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 13. To the extent that
any elimination in or reduction of payments or benefits is made under this Section 13, the determination as to the order in which payments and benefits shall be reduced shall be made by you
(subject, however, to the Company's approval if made on or after the date on which the event that triggers the payments or benefits occurs). 

        14.   Reimbursement of Attorneys' Fees.    The Company agrees to reimburse you up to a total of four thousand dollars
($4,000) for your legal counsel fees to review and provide advice to you regarding this Agreement and the enclosed Confidentiality Agreement. In order to receive such reimbursement, you must submit a
copy of the final invoice from your legal counsel, which may be redacted to prevent disclosure of attorney-client communications. 

        15.   Complete Agreement.    This letter, together with your Confidentiality Agreement and any other agreements
referenced herein, forms the complete, final and exclusive statement of your agreement with the Company with regard to the subject matters contained herein. It is entered into without reliance on any
promise or representation other than those expressly contained herein, and it supersedes and replaces any previous promises, representations or agreements. Other than those changes expressly reserved
to the Company's discretion in this letter, this letter agreement cannot be changed except in a written agreement approved by the Board and signed by you and a duly authorized officer of the Company.
Each party has carefully read this letter, has been afforded the opportunity to be advised of its meaning and consequences by your or its respective attorneys, and signs the same of your or its own

        16.   No Duty to Mitigate.    You are not under any contractual or legal obligation to mitigate your damages in order

	Re:
	Modification of Employment Terms

Dear
Kirk: 

As
we have discussed, this letter agreement confirms an amendment (the "Amendment") to the terms of your employment offer letter with
Epocrates, Inc. (the "Company") dated June 18, 2004 (the "Offer Letter"). The Amendment
will become effective only as of the effective date of the initial public offering of the Company's common stock (the "IPO"), and if the IPO does not
occur, this Amendment will not become effective. For the purposes of the Offer Letter and this Amendment, we agree that the IPO will not qualify as a Change of Control (defined in
Section 5(c)(ii) of the Offer Letter). 

The
Amendment is as follows: 

        1.     The reference to Paragraph 12(b) set forth in Section 5(b) of the Offer Letter shall be changed to reference
Paragraph 12(c). 

        2.     In the first sentence of Section 5(c)(iii) of the Offer Letter, the phrase "For purposes of this letter,
"Good Reason" following a Change of Control shall mean:" shall be replaced with the following phrase: "For purposes of this letter,
"Good Reason", at any time during the twelve (12) months following the consummation of a Change of Control, shall mean:". 

        3.     The last sentence of Section 5(c)(iii) of the Offer Letter shall be superseded in its entirety and replaced with
the following: 

Your
employment shall not be deemed to be terminated for "Good Reason" at any time during the twelve (12) months following the consummation of a Change of Control unless written notice stating
the basis for the termination is provided to the Company by you and the Company is given fifteen (15) days after receipt of such notice to cure the neglect or conduct that is the basis of such
claim (but only with respect to curable actions or failures to act). 

        4.     In the first sentence of Section 5(c)(iv) of the Offer Letter, the phrase "For the purposes of this letter, "Good
Reason", absent a Change of Control, shall mean:" shall be replaced with the following phrase: "For purposes of this letter, "Good Reason", at any time
other than during the twelve (12) months following the consummation of a Change of Control, shall mean:". 

        5.     Section 12 of the Offer Letter will be superseded in its entirety and replaced with the following: 

        12.    Severance.    

        a.    Severance Benefits Not In Connection With A Change of
Control.    If, at any time other than during the twelve (12) months following the consummation of a Change of Control (as defined in Section 5(c)(ii)),
the Company or any successor entity terminates your employment without Cause (as defined in Section 12(c)) or you resign for Good Reason (as defined in Section 5(c)(iv)) and, in either
event, if you first sign, date, and deliver to the Company a separation agreement that includes a general release of all known and unknown claims in the form provided to you by the Company, and allow
this separation agreement and release to become effective; then you will receive the following as your sole severance benefits (the "Severance
Benefits"): (i) severance pay equal to twelve (12) months of your base salary in effect as of the termination date, less required deductions and withholdings;
(ii) provided that you timely elect continued group health insurance coverage through federal COBRA law or 

1

 

comparable
state law (collectively, "COBRA"), the Company will pay your COBRA premiums sufficient to continue your group health insurance coverage at
the same level in effect as of your termination date for twelve (12) months after your termination or until you become eligible for group health insurance coverage through a new employer,
whichever occurs first; and (iii) accelerated vesting of the Shares subject to the Option equal to the lesser of either (A) the number of
unvested Shares that would have vested if your employment had continued for twelve (12) months after your termination date, or (B) all remaining unvested Shares; provided, however, that
nothing in this Section 12(a) shall limit or reduce the Acceleration described in Section 5(b) herein should you be entitled to such Acceleration. 

        b.    Change of Control Severance Benefits.    If, within twelve
(12) months after the consummation of a Change of Control (as defined in Section 5(c)(ii)), the Company or any successor entity terminates your employment without Cause or you resign for
Good Reason (as defined in Section 5(c)(iii)) and, in either event, if you first sign, date, and deliver to the Company a separation agreement that includes a general release of all known and
unknown claims in the form provided to you by the Company, and allow this separation agreement and release to become effective; then you will receive the following as your sole severance benefits (the
"Change in Control Severance Benefits"): (i) severance pay equal to eighteen (18) months of your base salary in effect as of the
termination date, less required deductions and withholdings; (ii) provided that you timely elect continued group health insurance coverage through COBRA, the Company will pay your COBRA
premiums sufficient to continue your group health insurance coverage at the same level in effect as of your termination date for eighteen (18) months after your termination or until you become
eligible for group health insurance coverage through a new employer, whichever occurs first; and (iii) any unvested shares subject to any option grants held by you as of the employment
termination date (including, but not limited to, any unvested Shares subject to the Option) will become vested and exercisable, effective as of the employment termination date;  provided, however, that
nothing in this Section 12(b) shall limit or reduce the Acceleration described in Section 5(b) herein should you
be entitled to such Acceleration. 

        c.    Definition of Cause.    For purposes of this letter agreement,
"Cause" means any of the following conduct by you: (i) embezzlement, misappropriation of corporate funds, or other material acts of dishonesty;
(ii) the conviction, plea of guilty, or nolo contendere to any felony (not involving the operation of a motor vehicle), or of any misdemeanor involving moral turpitude; (iii) engagement
in any activity that you know or should know could materially harm the business or reputation of the Company, provided that this subsection (iii) shall not apply to any activity done in a good
faith belief by you that the action taken or omission was in the best interest of the Company; (iv) material violation of any statutory, contractual, or common law duty or obligation owed by
you to the Company, including, without limitation, the duty of loyalty which causes demonstrable injury to the Company; (v) material breach of the Confidentiality Agreement; or
(vi) repeated failure, in the reasonable judgment of the Board, to substantially perform your assigned duties or responsibilities after written notice from the Board describing the failure(s)
in reasonable detail and your failure to cure such failure(s) within thirty (30) days of receiving such written notice, provided that written notice only must be provided if the failure(s) are
capable of cure. 

        d.    Form and Timing of Severance Payments.    Any severance pay
provided for in Section 12(a) or 12(b), as applicable, shall be paid in the form of salary continuation on the Company's standard payroll dates (beginning with the first payroll date following
the effective date of your required separation agreement); provided, however, that if you are a "specified employee" within the meaning of
Section 409A(a)(2)(B)(i) of the Internal Revenue Code of 1986, as amended (the "Code") at the time of your separation from service with the
Company, 

2

 

then
in accordance with Section 409A(a)(2)(B)(i) of the Code, the Company's payment of such amounts will be delayed until six (6) months after separation from service as follows:
(i) all amounts that would have been paid to you during the 6-month period following your separation from service (if such amounts were not subject to
Section 409A(a)(2)(B)(i) of the Code) shall be delayed and paid to you on the Company's first normal payroll date following such 6-month period, with no interest paid on account of
such delay, and (ii) the remaining amount of payments shall be paid to you in substantially equal installments on the Company's normal payroll dates over the following six (6) or twelve
(12) months, as applicable. 

        6.     Section 13 of the Offer Letter will be superseded in its entirety and replaced with the following: 

        13.    Parachute Payments.    In the event that the benefits provided
for in this letter agreement or otherwise payable to you ("Payment") would constitute "parachute payments" within the meaning of Section 280G of
the Code and, but for this sentence, would be subject to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), then such Payment
shall be equal to the Reduced Amount. The "Reduced Amount" shall be either (i) the largest portion of the Payment that would result in no portion
of the Payment being subject to the Excise Tax, or (ii) the largest portion, up to and including the total, of the Payment, whichever of the foregoing amounts, after taking into account all
applicable federal, state and local employment taxes, income taxes and the Excise Tax (all computed at the highest applicable marginal rate), results in the receipt by you, on an after-tax
basis, of the greater amount of the Payment, notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. Unless the Company and you otherwise agree in writing, the
determination of your Excise Tax liability shall be made in writing by the accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change of
Control (the "Accountants"). If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group
effecting the Change of Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. For purposes of making the calculations required by
this Section 13, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application
of Sections 280G and 4999 of the Code. Any good faith determinations of the Accountants made hereunder shall be final, binding, and conclusive upon the Company and you. The Company and you
shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations contemplated by this Section 13. To the extent that any elimination in or reduction of payments or benefits is made under
this Section 13, the determination as to the order in which payments and benefits shall be reduced shall be made by you (subject, however, to the Company's approval if made on or after the date
on which the event that triggers the payments or benefits occurs). 

Except
as modified herein, all other terms of the Offer Letter shall remain in full force and effect. 

This
Amendment, together with the Offer Letter, constitutes the entire agreement between you and the Company regarding the terms of your employment, effective as of the first business day of the IPO.
It supersedes any prior statements, representations or promises made to you concerning the subjects contained in this letter agreement and the Offer Letter, and only can be modified in a writing
signed by you and a duly authorized director or officer of Epocrates.
