 EXHIBIT 4.3 
 FORM OF “TYPE 1” HOLDER VOTING AGREEMENT 
 This Holder
Voting Agreement (the “Agreement”) is made as of the    day of                    ,
        , by and among Facebook, Inc., a Delaware corporation (f/k/a TheFacebook, Inc., the “Company”),
                    (the “Stockholder”) and Mark Zuckerberg (the “Proxyholder”). 

RECITALS 
 The Stockholder holds shares of Common Stock of the Company. This Agreement, among other things, requires the Stockholder to vote all such shares of Common Stock and all shares of capital stock of the
Company which such Stockholder currently owns or hereafter acquires or as to which he otherwise exercises voting or dispositive authority (together all such shares referred to in this sentence and any securities of the Company issued with respect
to, upon conversion of, or in exchange or substitution of such shares, and any other voting securities of the Company subsequently acquired by the Stockholder, the “Shares”) in the manner set forth herein. This agreement is being
entered into in exchange for a payment of $100 in cash from the Proxyholder to Stockholder and for other good and valuable consideration, the sufficiency of which is hereby acknowledged and agreed. 

AGREEMENT 
 The parties agree as follows: 
 1. Voting for the Election of
Directors. At each annual meeting of the stockholders of the Company, or at any meeting of the stockholders of the Company at which members of the Board of Directors of the Company are to be elected, or whenever members of the Board of
Directors are to be elected by written consent, the Stockholder agrees to vote (in person, by proxy or by action by written consent, as applicable) with respect to all Shares so as to elect the members of the Board of Directors designated in writing
by the Proxyholder. At any meeting of the stockholders of the Company at which members of the Board of Directors of the Company are to be removed, or whenever members of the Board of Directors are to be removed by written consent, the Stockholder
agrees to vote or act with respect to his Shares so as to remove any director designated in writing by Proxyholder. Notwithstanding the foregoing or anything to the contrary contained herein, to the extent that Stockholder and Proxyholder are both
parties (or become parties) to the Voting Agreement between the Company, certain stockholders and investors of the Company, dated as of April 29, 2005, as amended from time to time (the “Investor Voting Agreement”), Stockholder
agrees to continue to be bound by the Investor Voting Agreement and, to the extent that any provisions of this Agreement conflict with the provisions of the Investor Voting Agreement regarding the election or removal of directors (the
“Director Provisions”), the Director Provisions (including without limitation any proxies given with respect thereto) shall govern the election and removal of directors under this Agreement. Proxyholder agrees to continue to be
bound by the Investor Voting Agreement and shall vote (to the extent Proxyholder holds a proxy) and otherwise act with respect to any Shares as and if required under the Investor Voting Agreement. 

 2. Voting Agreement On All Matters. Stockholder hereby agrees with respect to
all Shares: 
 (a) In the event that the Proxyholder instructs (or otherwise requests) that Stockholder vote in favor of any
Acquisition (an “Approved Sale”), any Certificate Amendment and/or any Other Matter, then the Stockholder shall (i) after receiving proper notice of any meeting of stockholders of the Company to vote on the approval of an
Approved Sale, a Certificate Amendment and/or Other Matter (or, if no notice is required or such notice is properly waived, after notice from the Proxyholder is given), be present, in person or by proxy, as a holder of Shares at all such meetings
and be counted for the purposes of determining the presence of a quorum at such meetings and (ii) vote (in person, by proxy or by action by written consent, as applicable) all Shares as to which the Stockholder has beneficial ownership or as to
which he otherwise exercises voting or dispositive authority (A) in favor of such Approved Sale or Certificate Amendment, (B) in the case of an Approved Sale, in opposition of any and all other Acquisitions for which a vote is taken while
an Approved Sale is still pending that would reasonably be expected to delay or impair the ability of the Company to consummate such Approved Sale, and (C) in the case of an Other Matter, in the manner directed by the Proxyholder.
Notwithstanding the foregoing, in the case of an Approved Sale, the Stockholder shall not be required to assume personal liability greater than the liability assumed by the Proxyholder that continues after the transaction closing for breach of
representations, warranties or other obligations except (x) to the extent of the consideration received in the transaction or (y) for liability attributable to fraud or willful misconduct on the part of the Stockholder. The Stockholder
shall refrain from exercising any dissenters’ rights, appraisal rights or similar rights under applicable law at any time in connection with such Approved Sale. If the Approved Sale is structured as a sale of the stock of the Company, then the
Stockholder hereby agrees to sell and shall sell all of his Shares on the terms and conditions approved by the Proxyholder. Subject to applicable laws, the Stockholder shall take all necessary and desirable actions approved by the Proxyholder in
connection with the consummation of the Approved Sale, including the execution of such agreements and such instruments and other actions reasonably necessary to (i) provide the representations, warranties, indemnities, covenants, conditions,
escrow agreements and other provisions and agreements relating to such Approved Sale, and (ii) effectuate the allocation and distribution of the aggregate consideration upon consummation of the Approved Sale. 

(b) In the event that the Proxyholder instructs (or otherwise requests) that Stockholder vote against any Acquisition (a
“Rejected Sale”), any Certificate Amendment and/or any Other Matter, then the Stockholder shall (i) after receiving proper notice of any meeting of stockholders of the Company to vote on the Rejected Sale, such Certificate
Amendment and/or Other Matter (or, if no notice is required or such notice is properly waived, after notice from the Proxyholder is given), be present, in person or by proxy, as a holder of Shares at all such meetings and be counted for the purposes
of determining the presence of a quorum at such meetings and (ii) vote (in person, by proxy or by action by written consent, as applicable) all Shares as to which the Stockholder has beneficial ownership or as to which he otherwise exercises
voting or dispositive authority (A) against such Rejected Sale or Certificate Amendment, and (B) in the case of an Other Matter, in the manner directed by the Proxyholder. If the Rejected Sale is structured as a sale of the stock of the
Company, then the Stockholder shall not sell any of his Shares unless permitted to sell in writing by the Proxyholder. 
 (c)
Stockholder agrees that, unless Proxyholder provides explicit written instruction to vote Stockholder’s Shares under this Agreement or Proxyholder provides explicit written notice that Stockholder shall be permitted by Proxyholder to vote in a
manner other than as Proxyholder instructs, Stockholder shall abstain from voting any of his Shares (in person, by proxy or by action by written consent, as applicable) on all matters. 

  
 2 

 (d) In the event of any Transfer by the Stockholder, (i) the Stockholder shall inform
the Company and the Proxyholder of such Transfer and (ii) the pledgee, transferee or donee shall furnish the Proxyholder and the Company with a written agreement to be bound by the provisions of this Agreement. Such Transfer shall not be valid
unless and until the Company and the Proxyholder receive such written agreement. In the event of any Transfer by the Stockholder, the Stockholder shall inform the Company and the Proxyholder of such Transfer no less than 5 business days prior to
such Transfer. Such pledgee, transferee or donee shall be treated as a “Stockholder” for purposes of this Agreement. For avoidance of doubt, the Company shall not permit the transfer of any of the Shares on its books or issue new
certificates representing any such Shares unless and until the person(s) to whom such Shares are to be transferred shall have executed the written agreement referred to in this Section 2 and any additional agreement required under any other
applicable agreements between the parties hereto. 
 For purposes of this Section 2: 

“Acquisition” shall mean any (i) event that results in a liquidation, dissolution or winding up, or is deemed to be
a liquidation, dissolution or winding up of the Company under the Company’s Certificate of Incorporation, as the same may be amended from time to time (the “Certificate”) or any (ii) reorganization, consolidation, merger,
stock sale, or asset sale of the Company. 
 “Certificate Amendment” shall mean any amendment of the
Certificate. 
 “Other Matter” shall mean any matter, action, ratification or other event other than an
Acquisition or Certificate Amendment for which approval of the holders of the Company’s stock is sought (either by vote or written consent) or upon which such holders are otherwise entitled to vote or consent. 

“Transfer” shall mean and include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift,
transfer by bequest, devise or descent, or other transfer or disposition of any kind, including, but not limited to, transfers to receivers, levying creditors, trustees or receivers in bankruptcy proceedings or general assignees for the benefit of
creditors, whether voluntary or by operation of law, directly or indirectly, of any of the Shares. 
 3. Irrevocable Proxy
and Power of Attorney. To secure the Stockholder’s obligations to vote the Shares in accordance with this Agreement and to comply with the other terms hereof, the Stockholder hereby appoints the Proxyholder, or his designees, as such
Stockholder’s true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote or act by written consent with respect to all of such Stockholder’s Shares in accordance with the provisions set
forth in this Agreement, and to execute all appropriate instruments consistent with this Agreement on behalf of such Stockholder. The proxy and power granted by the Stockholder pursuant to this Section are coupled with an interest and are given to
secure the performance of such party’s duties under this Agreement. Each such 

  
 3 

 
proxy and power will be irrevocable for the term hereof. The proxy and power, so long as any party hereto is an individual, will survive the death, incompetency and disability of such party or
any other individual holder of the Shares and, so long as any party hereto is an entity, will survive the merger, consolidation, conversion or reorganization of such party or any other entity holding any Shares.

term of this Agreement. 
 4.2 Legends. The Company shall cause each certificate representing shares of the
Company’s capital stock held by the Stockholder or any assignee of the Stockholder to bear the following legend:

SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID VOTING AGREEMENT.” 
 4.3 Stock Splits, Dividends, Etc. In the event of any issuance of Shares of the Company’s voting securities hereafter to any of the parties hereto (including, without limitation, in
connection with any stock split, stock dividend, recapitalization, reorganization, or the like), such shares shall automatically become subject to this Agreement and shall be endorsed with the legend set forth in Section 4.2. 

4.4 Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured
party for the breach of this Agreement by any party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining

reporting requirements, rules and regulations of the Exchange Act of 1934, as amended, the Securities Act of 1933, as amended, and/or any state and federal securities laws (collectively, the “Securities Laws”). Stockholder agrees to

by and among Facebook, Inc., a Delaware corporation (the “Company”),                     (together with its successors,
“Stockholder”), and Mark Zuckerberg (“Proxyholder”). 
 RECITALS 

A. Stockholder is purchasing and will hold shares of             
                          of the Company and is party to that certain Fourth Amended and Restated Voting Agreement by and among
the Company, the Founders (as defined therein), Peter Thiel and the Investors (as defined therein), dated as of even date herewith (the “Investor Voting Agreement”). 

B. This Agreement, among other things, requires Stockholder to vote all such shares of
                                       and all shares of capital
stock of the Company which Stockholder hereafter acquires or as to which Stockholder otherwise exercises voting or dispositive authority (together, all such shares referred to in this sentence and any securities of the Company issued with respect
to, upon conversion of, or in exchange or substitution of such shares, the “Shares”) in the manner set forth herein. 
 C. This Agreement is being entered into in exchange for a payment of U.S. $100 in cash from Proxyholder to Stockholder and for other good and valuable consideration, the sufficiency of which is hereby
acknowledged and agreed. 
 AGREEMENT 
 The parties agree as follows: 
 1. No Conflict with Investor Voting
Agreement. In the event of a conflict between the terms and provisions of this Agreement and the terms and provisions of the Investor Voting Agreement, the terms and provisions of the Investor Voting Agreement will prevail, and Proxyholder
or Stockholder, as the case may be, shall be obligated to vote the Shares in accordance with the Investor Voting Agreement. 

2. Voting Arrangements. Stockholder hereby agrees that Proxyholder shall have the right to vote all the Shares, in his sole
discretion, on all matters submitted to a vote of stockholders of the Company at a meeting of stockholders or through the solicitation of a written consent of stockholders (whether of any individual class of stock or of multiple classes of stock
voting together) except for: 
 2.1 Any issuance, or series of related issuances, of capital stock in a capital raising
transaction by the Company that is submitted for stockholder approval in which the number of shares of capital stock so issued will exceed 20% of the total number of shares of capital stock of the Company outstanding immediately prior to such
issuance; and 
 2.2 Any matter, the outcome of the vote on which would disproportionately, materially and adversely affect
Stockholder, as compared to other holders of the same class(es) 

 
of capital stock of Company, provided that, subject to Section 2.1, increases in the authorized number of shares of preferred stock generally, or the authorized number of any class of
preferred stock of the Company or the issuance of securities of the Company senior to such class of preferred stock will not be viewed as having such an adverse effect). 
 With respect to the excepted matters described in Sections 2.1 and 2.2 above, Stockholder shall have the right to (i) instruct Proxyholder in writing as to the manner in which the Shares shall be
voted or (ii) vote the Shares in person or by action by written consent, as applicable, in which case Stockholder shall notify Proxyholder in writing that it intends to so vote. In addition, Proxyholder shall not have any right to waive notice
by the Company to Stockholder. Such instruction or notice shall be provided to Proxyholder at least five (5) days prior to the date of any meeting of stockholders at which such matter is to be voted upon or as promptly as reasonably practicable
upon Stockholder becoming aware that such matter is to be acted upon by written consent. In the event that Stockholder does not so instruct Proxyholder or notify Proxyholder of its intention to so vote or act by written consent, Proxyholder shall
abstain from voting the Shares in respect of such matters. 
 3. Illustrative Examples. Matters on which
Proxyholder shall be entitled to vote, pursuant to Section 2 include, but are not limited to, the following, which are presented here solely by way of example: 
 3.1 Election, replacement or removal of directors of the Company (each, a “Director”); 
 3.2 Sale or other disposition of all or substantially all of the Company’s assets, provided, that any distribution to Company stockholders of the proceeds of such sale or disposition are made
in accordance with the Company’s certificate of incorporation, as then in effect; 
 3.3 Mergers of, or acquisitions by,
the Company or its subsidiaries that are submitted for stockholder approval; 
 3.4 Adoption by the Company of a rights plan or
similar takeover defensive arrangements, or amendments thereof, which plan provides that a triggering event will occur only upon the acquisition by a stockholder of 15% or more of the Company’s shares of voting capital stock; and 

3.5 Adoption by the Company of a two-class capital stock structure (a “Dual Class Structure”) in which one class of
capital stock has, among other things, enhanced voting rights, including but not necessarily limited to multiple votes per share (“Heavy Vote Stock”), and the other class of capital stock does not (“Low Vote
Stock”), provided, that, the shares of capital stock held by Stockholder at the time of adoption of such structure are entitled to be converted into Heavy Vote Stock. 

4. Stockholder to Abstain from Voting. Stockholder agrees that, unless Proxyholder provides explicit written instruction to
vote the Shares under this Agreement or Proxyholder provides explicit written notice that Stockholder shall be permitted by Proxyholder to vote in a manner other than as Proxyholder instructs, Stockholder shall abstain from voting any of the Shares
(in person, by proxy or by action by written consent, as applicable) on all matters other than with respect to the matters set forth in Section 2.1 and 2.2. 

  
 2 

 5. Irrevocable Proxy and Power of Attorney. To secure Stockholder’s
obligations to vote the Shares in accordance with this Agreement and to comply with the other terms hereof, Stockholder hereby appoints Proxyholder, or his designees, as Stockholder’s true and lawful proxy and attorney, with the power to act
alone and with full power of substitution, to vote or act by written consent with respect to all the Shares in accordance with the provisions set forth in this Agreement, and to execute all appropriate instruments consistent with this Agreement on
behalf of Stockholder. The proxy and power granted by Stockholder pursuant to this Section are coupled with an interest and are given to secure the performance of Stockholder’s duties under this Agreement. The proxy and power will be
irrevocable for the term hereof. The proxy and power will survive the merger, consolidation, conversion or reorganization of Stockholder or any other entity holding the Shares. 

6. Additional Representations, Covenants and Agreements. 

6.1 Transfers by Stockholder. 
 (a) Stockholder hereby acknowledges that Proxyholder is an intended third-party beneficiary of the Third Amended and Restated Right of First Refusal and Co-Sale Agreement by and among the Founders (as
defined therein), the Company and the Investors (as defined therein) dated as of even date herewith (the “ROFR Agreement”). 
 (b) Pursuant to Section 5 of the ROFR Agreement, Stockholder may not transfer, assign, pledge or otherwise dispose of or encumber the Shares (collectively, a “Transfer”) without the
prior written consent of the Company, unless otherwise permitted by the ROFR Agreement. 
 (c) If
Stockholder’s Transfer of Shares is permitted under the terms of the ROFR Agreement or is otherwise consented to by the Company pursuant to the ROFR Agreement, such Transfer shall not take effect until the pledgee, transferee or donee of such
Shares (the “Transferee”) furnishes Proxyholder and the Company with a written agreement to be bound by the terms of this Agreement (an “Assumption Agreement”) and any additional agreement required under any other
applicable agreements between the parties hereto, it being understood and agreed that the Company shall be entitled to issue stop transfer instructions in respect of such Shares to preclude any transfer of Shares in contravention of the foregoing.
Notwithstanding the foregoing, following the completion of a firm commitment underwritten public offering by the Company under the Securities Act of 1933, as amended (the “Securities Act”) the Transferee shall not be required to

 3 

 (ii) the shares of capital stock being transferred, in either a
single transaction or series of related transactions, represent less than 3.17% of the aggregate number of shares of the Company’s voting capital stock then outstanding. 
 Upon satisfaction of the provisions of this Section 6.2, such pledgee, transferee or donee shall be treated as a “Stockholder” for purposes of this Agreement. 

6.2 Legends. The Company shall cause each certificate representing the Shares to bear the following legend: 

“THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A HOLDER VOTING AGREEMENT BY AND AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE
COMPANY (A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY) WHICH INCLUDES PROVISIONS POTENTIALLY RESTRICTING THE STOCKHOLDER’S RIGHT TO VOTE OR TRANSFER HIS OR ITS ENTIRE INTEREST IN THE SHARES EVIDENCED HEREBY, AND BY ACCEPTING ANY INTEREST IN
SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID HOLDER VOTING AGREEMENT.” 
 6.3 Stock Splits, Dividends, Etc. In the event of any issuance of shares of the Company’s voting securities hereafter to Stockholder (including, without limitation, in connection with
any stock split, stock dividend, recapitalization, reorganization, or the like), such shares shall automatically become subject to this Agreement and shall be endorsed with the legend set forth in Section 6.2. 

6.4 Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured
party for the breach of this Agreement by any party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining
order. Further, each party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach. 
 6.5 Securities Laws, Rules and Regulations. Stockholder, the Company and Proxyholder agree and understand that Stockholder, the Company and/or Proxyholder may become subject to the
registration and/or reporting requirements, rules and regulations of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Securities Act and/or any state and federal securities laws (collectively with the
Exchange Act and the Securities Act, the “Securities Laws”). Stockholder, the Company and Proxyholder agree to use their respective commercially reasonable efforts to comply with the Securities Laws and to reasonably assist each
other in complying with the Securities Laws in a timely and prompt manner. Such compliance may include, for example and without limiting the foregoing, the filing and updating and maintaining of Form 13G and/or Form 13D under the Exchange Act.

  
 4 

 6.6 Other Arrangements. During the term of this Agreement Stockholder will
not, without Proxyholder’s written consent: 
 (a) offer, seek or propose to acquire or cause to be acquired, any
ownership of any assets or business of the Company or any of its subsidiaries, or seek to propose or propose, whether alone or in concert with other persons, any tender offer (other than as contemplated by the Transaction Agreements, as defined in
the Series E Preferred Stock Purchase Agreement, dated as of May 16, 2009, by and between the Company and Stockholder), exchange offer, merger, business combination, restructuring, liquidation, recapitalization or similar transaction involving
the Company or any of its subsidiaries; 
 (b) make, or in any way participate in, any “solicitation” of

the voting of their securities of the Company; 
 (c) form, join, or in any way become a member of a 13D Group with respect to

plan or arrangement inconsistent with the foregoing.

7.1 Termination Events. This Agreement shall terminate: 

(a) upon the liquidation, dissolution or winding up of the business operations of the Company; 

(b) upon the execution by the Company of a general assignment for the benefit of creditors or the appointment of a receiver or trustee
to take possession of the property and assets of the Company; 
 (c) in the sole discretion of Proxyholder, upon the express
written consent of Proxyholder (which he shall be under no obligation to provide); 
 (d) upon the death or permanent and
substantial incapacity of Proxyholder, as determined in good faith by the Company’s board of directors, unless Proxyholder is actively contesting such determination of incapacity; or 

(e) Six (6) months after the later of the date on which Proxyholder (i) ceases to be Chief Executive Officer
(“CEO”) of the Company, and (ii) is no longer Actively Engaged in the management of the Company, where “Actively Engaged” is defined as Proxyholder (I) being a Director, (II) devoting substantially all of
his business efforts to the Company, and (III) owning at least 50% (the “Threshold Amount”) of the shares of capital stock of the Company owned by him as of the date of this Agreement (as adjusted for any stock split, stock
dividend, recapitalization, reorganization or the like). Notwithstanding the foregoing, the date of termination of this Agreement pursuant to this Section 7.1(e) will be 12 (twelve) months after such later date if (x) Proxyholder is
actively contesting his removal as CEO or Director, or (y) has ceased to be Actively Engaged due to having taken a leave of absence for medical reasons, provided, however, that if at any time Proxyholder is not CEO (and he is not
actively contesting his removal as CEO) and he ceases to be Actively Engaged due to his owning less than the Threshold Amount, this Agreement shall terminate immediately upon the date as of which he ceases to own less than the Threshold Amount.

 7.2 Removal of Legend. At any time after the termination of this Agreement in accordance with Section 7.1,
any holder of a stock certificate legended pursuant to this Agreement may surrender such certificate to the Company for removal of the legend, and the Company shall, as promptly as reasonably practicable, reissue a new certificate without the

claim that it is not subject to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

by law, service of any process, summons, notice or document by U.S. registered mail to the parties’ respective addresses set forth on the signature page hereto shall be effective service of process for any suit or proceeding in connection with
