 ADOPTED BY
THE BOARD OF DIRECTORS: JULY 24, 2007 
 APPROVED BY THE STOCKHOLDERS: OCTOBER 8, 2007 
 1.
GENERAL. 
 (a) The purpose of the Plan is to provide a means by which Eligible Employees of the Company and certain
designated Related Corporations may be given an opportunity to purchase shares of Common Stock. The Plan is intended to permit the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan. 

(b) The Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and
to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related Corporations. 
 2.
ADMINISTRATION. 
 (a) The Board shall administer the Plan unless and until the Board delegates administration of
the Plan to a Committee or Committees, as provided in Section 2(c). 
 (b) The Board shall have the power, subject to, and within
the limitations of, the express provisions of the Plan: 
 (i) To determine how and when Purchase Rights to purchase shares of Common
Stock shall be granted and the provisions of each Offering comprised of such Purchase Rights (which need not be identical). 
 (ii) To
designate from time to time which Related Corporations of the Company shall be eligible to participate in the Plan. 
 (iii) To
construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for administration of the Plan. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in
a manner and to the extent it shall deem necessary or expedient to make the Plan or Purchase Rights fully effective. 
 (iv) To settle
all controversies regarding the Plan and Purchase Rights granted under it. 
 (v) To suspend or terminate the Plan at any time.
Suspension or termination of the Plan shall not impair rights and obligations under any Purchase Right granted while the Plan is in effect except with the written consent of the affected Participant. 
  

 1. 








 (vi) To amend the Plan in any respect the Board deems necessary or advisable. However, except as
provided in Section 12(a) relating to Capitalization Adjustments, stockholder approval shall be required for any amendment of the Plan that either (i) materially increases the number of shares of Common Stock available for issuance under
the Plan, (ii) materially expands the class of individuals eligible to become Participants and receive Purchase Rights under the Plan, (iii) materially increases the benefits accruing to Participants under the Plan or materially reduces
the price at which shares of Common Stock may be purchased under the Plan, (iv) materially extends the term of the Plan, or (v) expands the types of awards available for issuance under the Plan, but in each of (i) through
(v) only to the extent required by applicable law or listing requirements. Except as provided above, the rights and obligations under any Purchase Rights granted before amendment of the Plan shall not be impaired by any amendment of the Plan
except: (i) with the consent of the person to whom such Purchase Rights were granted, or (ii) as necessary to comply with any laws or governmental regulations (including, without limitation, the provisions of the Code and the regulations
promulgated thereunder relating to Employee Stock Purchase Plans). 
 (vii) Generally, to exercise such powers and to perform such
acts as it deems necessary or expedient to promote the best interests of the Company and its Related Corporations and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan. 
 (viii) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign
nationals or employed outside the United States. 
 (c) The Board may delegate some or all of the administration of the Plan to a
Committee or Committees. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including
the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), 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 Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of
the powers previously delegated. 
 (d) All determinations, interpretations and constructions made by the Board in good faith shall
not be subject to review by any person and shall be final, binding and conclusive on all persons. 
 3. SHARES OF
COMMON STOCK SUBJECT TO THE PLAN. 
 (a)
Subject to the provisions of Section 12(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be sold pursuant to Purchase Rights shall not exceed four hundred sixty-one thousand five hundred
thirty-eight (461,538) shares. In addition, the number of shares of Common Stock available for issuance under the Plan shall automatically increase on January 1st of each year commencing in 2008 and ending on (and including) January 1,
2017, in an amount equal to the lesser of (i) one and one-half percent (1.5%) of the total number of shares 

  

 2. 








 
of Common Stock outstanding on December 31st of the preceding calendar year, or (ii) two million three hundred seven thousand six hundred
ninety-two (2,307,692) shares of Common Stock. Notwithstanding the foregoing, the Board may act prior to the first day of any calendar year, to provide that there shall be no increase in the share reserve for such calendar year or that the increase
in the share reserve for such calendar year shall be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. 
 (b) If any Purchase Right granted under the Plan shall for any reason terminate without having been exercised, the shares of Common Stock not purchased under such Purchase Right shall again become available for
issuance under the Plan. 
 (c) The stock purchasable under the Plan shall be shares of authorized but unissued or reacquired Common
Stock, including shares repurchased by the Company on the open market. 
 4. GRANT OF PURCHASE
RIGHTS; OFFERING. 
 (a) The Board may from time to time grant or provide for the grant of Purchase
Rights to purchase shares of Common Stock under the Plan to Eligible Employees in an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate, which shall comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights shall have the same rights and privileges. The terms and
conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering shall include (through incorporation of the provisions of this
Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering shall be effective, which period shall not exceed twenty-seven (27) months beginning with the Offering Date, and the substance of the
provisions contained in Sections 5 through 8. 
 (b) If a Participant has more than one Purchase Right outstanding under the Plan,
unless he or she otherwise indicates in agreements or notices delivered hereunder: (i) each agreement or notice delivered by that Participant shall be deemed to apply to all of his or her Purchase Rights under the Plan, and (ii) a Purchase
Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) shall be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a
later-granted Purchase Right if different Purchase Rights have identical exercise prices) shall be exercised. 
 (c) The Board shall
have the discretion to structure an Offering so that if the Fair Market Value of a share of Common Stock on any Purchase Date within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for
that Offering, then (i) that Offering shall terminate immediately following the purchase of shares of Common Stock on such Purchase Date, and (ii) Participants in the terminated Offering automatically shall be enrolled in the Offering that
commences immediately after such Purchase Date. 
  

 3. 








 5. ELIGIBILITY. 
 (a) Purchase Rights may be granted only to Employees of the Company or, as the Board may designate as provided in Section 2(b), to Employees of a Related Corporation. Except as provided in
Section 5(b), an Employee shall not be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such Employee has been in the employ of the Company or the Related Corporation, as the case may be, for such continuous
period preceding such Offering Date as the Board may require, but in no event shall the required period of continuous employment be greater than two (2) years. In addition, the Board may provide that no Employee shall be eligible to be granted
Purchase Rights under the Plan unless, on the Offering Date, such Employee’s customary employment with the Company or the Related Corporation is more than twenty (20) hours per week and more than five (5) months per calendar year or
such other criteria as the Board may determine consistent with Section 423 of the Code. 
 (b) The Board may provide that each
person who, during the course of an Offering, first becomes an Eligible Employee shall, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a
Purchase Right under that Offering, which Purchase Right shall thereafter be deemed to be a part of that Offering. Such Purchase Right shall have the same characteristics as any Purchase Rights originally granted under that Offering, as described
herein, except that: 
 (i) the date on which such Purchase Right is granted shall be the “Offering Date” of such Purchase
Right for all purposes, including determination of the exercise price of such Purchase Right; 
 (ii) the period of the Offering with
respect to such Purchase Right shall begin on its Offering Date and end coincident with the end of such Offering; and 
 (iii) the
Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, he or she shall not receive any Purchase Right under that Offering. 
 (c) No Employee shall be eligible for the grant of any Purchase Rights under the Plan if, immediately after any such Purchase Rights are granted,
such Employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of
Section 424(d) of the Code shall apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase Rights and options shall be treated as stock owned by such Employee.

 (d) As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights under the Plan only if
such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase stock of the Company or any Related
Corporation to accrue at a rate which exceeds twenty five thousand dollars ($25,000) of Fair Market Value of such stock (determined at the time such rights are granted, and which, with respect to the Plan, shall be determined as of their respective
Offering Dates) for each calendar year in which such rights are outstanding at any time. 
  

 4. 








 (e) Officers of the Company and any designated Related Corporation, if they are otherwise Eligible
Employees, shall be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the
Code shall not be eligible to participate. 
 6. PURCHASE RIGHTS; PURCHASE PRICE.

 (a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, shall be granted a Purchase
Right to purchase up to that number of shares of Common Stock purchasable either with a percentage or with a maximum dollar amount, as designated by the Board, but in either case not exceeding fifteen percent (15%) of such Employee’s
earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later
than the end of the Offering. 
 (b) The Board shall establish one (1) or more Purchase Dates during an Offering as of which
Purchase Rights granted pursuant to that Offering shall be exercised and purchases of shares of Common Stock shall be carried out in accordance with such Offering. 
 (c) In connection with each Offering made under the Plan, the Board may specify a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering. In
connection with each Offering made under the Plan, the Board may specify a maximum aggregate number of shares of Common Stock that may be purchased by all Participants pursuant to such Offering. In addition, in connection with each Offering that
contains more than one Purchase Date, the Board may specify a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of shares of Common Stock
issuable upon exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata allocation of the shares of Common Stock available shall be made in
as nearly a uniform manner as shall be practicable and equitable. 
 (d) The purchase price of shares of Common Stock acquired
pursuant to Purchase Rights shall be not less than the lesser of: 
 (i) an amount equal to eighty-five percent (85%) of the Fair
Market Value of the shares of Common Stock on the Offering Date; or 
 (ii) an amount equal to eighty-five percent (85%) of the
Fair Market Value of the shares of Common Stock on the applicable Purchase Date. 
  

 5. 








 7. PARTICIPATION; WITHDRAWAL; TERMINATION. 
 (a) A Participant may elect to authorize payroll deductions pursuant to an Offering under the Plan by completing and delivering to the Company,
within the time specified in the Offering, an enrollment form (in such form as the Company may provide). Each such enrollment form shall authorize an amount of Contributions expressed as a percentage of the submitting Participant’s earnings (as
defined in each Offering) during the Offering (not to exceed the maximum percentage specified by the Board). Each Participant’s Contributions shall be credited to a bookkeeping account for such Participant under the Plan and shall be deposited
with the general funds of the Company except where applicable law requires that Contributions be deposited with a third party. To the extent provided in the Offering, a Participant may begin such Contributions after the beginning of the Offering. To
the extent provided in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. To the extent specifically provided in the Offering, in addition to making Contributions by payroll deductions, a
Participant may make Contributions through the payment by cash or check prior to each Purchase Date of the Offering. 
 (b) During an
Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company may provide. Such withdrawal may be elected at any time prior to the end of the
Offering, except as provided otherwise in the Offering. Upon such withdrawal from the Offering by a Participant, the Company shall distribute to such Participant all of his or her accumulated Contributions (reduced to the extent, if any, such
Contributions have been used to acquire shares of Common Stock for the Participant) under the Offering, and such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from an Offering shall
have no effect upon such Participant’s eligibility to participate in any other Offerings under the Plan, but such Participant shall be required to deliver a new enrollment form in order to participate in subsequent Offerings. 
 (c) Purchase Rights granted pursuant to any Offering under the Plan shall terminate immediately upon a Participant ceasing to be an Employee for
any reason or for no reason (subject to any post-employment participation period required by law) or other lack of eligibility. The Company shall distribute to such terminated or otherwise ineligible Employee all of his or her accumulated
Contributions (reduced to the extent, if any, such Contributions have been used to acquire shares of Common Stock for the terminated or otherwise ineligible Employee) under the Offering. 
 (d) Purchase Rights shall not be transferable by a Participant except by will, the laws of descent and distribution, or by a beneficiary
designation as provided in Section 10. During a Participant’s lifetime, Purchase Rights shall be exercisable only by such Participant. 
 (e) Unless otherwise specified in an Offering, the Company shall have no obligation to pay interest on Contributions. 
  

 6. 








 8. EXERCISE OF PURCHASE RIGHTS. 
 (a) On each Purchase Date during an Offering, each Participant’s accumulated Contributions shall be applied to the purchase of shares of
Common Stock up to the maximum number of shares of Common Stock permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares shall be issued upon the exercise of
Purchase Rights unless specifically provided for in the Offering. 
 (b) If any amount of accumulated Contributions remains in a
Participant’s account after the purchase of shares of Common Stock and such remaining amount is less than the amount required to purchase one share of Common Stock on the final Purchase Date of an Offering, then such remaining amount shall be
held in such Participant’s account for the purchase of shares of Common Stock under the next Offering under the Plan, unless such Participant withdraws from such next Offering, as provided in Section 7(b), or is not eligible to participate
in such Offering, as provided in Section 5, in which case such amount shall be distributed to such Participant after the final Purchase Date, without interest. If the amount of Contributions remaining in a Participant’s account after the
purchase of shares of Common Stock is at least equal to the amount required to purchase one (1) whole share of Common Stock on the final Purchase Date of the Offering, then such remaining amount shall be distributed in full to such Participant
at the end of the Offering without interest. 
 (c) No Purchase Rights may be exercised to any extent unless the shares of Common
Stock to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable federal, state, foreign and other securities and other
laws applicable to the Plan. If on a Purchase Date during any Offering hereunder the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights or any Offering shall be exercised on such Purchase Date, and
the Purchase Date shall be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in such compliance, except that the Purchase Date shall not be delayed more than twelve (12) months and
the Purchase Date shall in no event be more than twenty-seven (27) months from the Offering Date. If, on the Purchase Date under any Offering hereunder, as delayed to the maximum extent permissible, the shares of Common Stock are not registered
and the Plan is not in such compliance, no Purchase Rights or any Offering shall be exercised and all Contributions accumulated during the Offering (reduced to the extent, if any, such Contributions have been used to acquire shares of Common Stock)
shall be distributed to the Participants without interest. 
 9. COVENANTS OF THE COMPANY.

 The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over
the Plan such authority as may be required to issue and sell shares of Common Stock upon exercise of the Purchase Rights. If, after commercially reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the
authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Purchase Rights
unless and until such authority is obtained. 
  

 7. 








 10. DESIGNATION OF BENEFICIARY. 
 (a) A Participant may file a written designation of a beneficiary who is to receive any shares of Common Stock and/or cash, if any, from the
Participant’s account under the Plan in the event of such Participant’s death subsequent to the end of an Offering but prior to delivery to the Participant of such shares of Common Stock or cash. In addition, a Participant may file a
written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death during an Offering. Any such designation shall be on a form provided by or otherwise
acceptable to the Company. 
 (b) The Participant may change such designation of beneficiary at any time by written notice to the
Company. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such shares of Common Stock and/or cash
to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares of Common Stock and/or cash
to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 
 11. MISCELLANEOUS PROVISIONS. 
 (a) The Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering shall in any way alter the at will nature of a Participant’s employment or be deemed to create in any way whatsoever any
obligation on the part of any Participant to continue in the employ of the Company or a Related Corporation, or on the part of the Company or a Related Corporation to continue the employment of a Participant. 
 (b) The provisions of the Plan shall be governed by the laws of the State of California without resort to that state’s conflicts of laws
rules. 
 (c) Proceeds from the sale of shares of Common Stock pursuant to Purchase Rights shall constitute general funds of the
Company. 
 (d) A Participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to,
shares of Common Stock subject to Purchase Rights unless and until the Participant’s shares of Common Stock acquired upon exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent). 
 12. ADJUSTMENTS UPON CHANGES IN COMMON STOCK; CORPORATE
TRANSACTIONS. 
 (a) In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately
adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase automatically each year pursuant to
Section 3(a), (iii) the class(es) and number of securities subject to outstanding Purchase Rights, and (iv) the class(es) and number of securities imposed by purchase limits under each ongoing Offering. The Board shall make such
adjustments, and its determination shall be final, binding and conclusive. 
  

 8. 








 (b) In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring
corporation (or the surviving or acquiring corporation’s parent company) may assume or continue Purchase Rights outstanding under the Plan or may substitute similar rights (including a right to acquire the same consideration paid to the
stockholders in the Corporate Transaction) for those outstanding under the Plan, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights
for Purchase Rights outstanding under the Plan, then the Participants’ accumulated Contributions shall be used to purchase shares of Common Stock within ten (10) business days prior to the Corporate Transaction under any ongoing Offerings,
and the Participants’ Purchase Rights under the ongoing Offerings shall terminate immediately after such purchase. 
 13. TERMINATION
OR SUSPENSION OF THE PLAN. 
 (a) The Board may suspend
or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate at the time that all of the shares of Common Stock reserved for issuance under the Plan, as increased and/or adjusted from time to time, have been issued under the
terms of the Plan. No Purchase Rights may be granted under the Plan while the Plan is suspended or after it is terminated. 
 (b) Any
benefits, privileges, entitlements and obligations under any Purchase Rights while the Plan is in effect shall not be impaired by suspension or termination of the Plan except (i) as expressly provided in the Plan or with the consent of the
person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, regulations or listing requirements, or (iii) as necessary to ensure that the Plan and/or Purchase Rights comply with the requirements of
Section 423 of the Code. 
 14. EFFECTIVE DATE OF PLAN. 
 The Plan shall become effective on the IPO Date, but no Purchase Rights shall be exercised unless and until the Plan has been approved by the stockholders
of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.

 OFFERING DOCUMENT 
 ADOPTED BY THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS: 
 OCTOBER 15, 2007 
 In this document, capitalized terms not otherwise defined shall have the same definitions of such terms as in the Entropic Communications, Inc. 2007 Employee Stock Purchase Plan. 
 1. GRANT; OFFERING DATE. 
 (a) The Board hereby authorizes a series of Offerings pursuant to the terms of this Offering document. 
 (b) The first Offering hereunder (the “Initial Offering”) shall begin on the date the Common Stock is first offered to the public under a registration statement declared effective under the Securities Act and
shall end on [                    , 2008], unless terminated earlier as provided below. The Initial Offering shall consist of two
(2) Purchase Periods, with the first Purchase Period ending on [                , 2008] and the second Purchase Period ending on
[                , 2008]. 
 (c) After the
Initial Offering commences, a concurrent Offering shall begin on [                    , 2008] and each
[            ] and [                ] thereafter over the term of the Plan and shall be
approximately twelve (12) months in duration. Each Offering shall consist of two (2) Purchase Periods, each of which shall be approximately six (6) months in length ending on or about
[                ] and [                ] each year. Except as provided
below, a Purchase Date is the last day of a Purchase Period or of an Offering, as the case may be. 
 (d) Notwithstanding the
