Right”), in each case, with or without cause at any time, by sending a written notice to such Director and the Corporation’s Secretary stating the name of the Director or Directors whose resignation from the Board is requested (the
“Removal Notice”). If the Director subject to such Removal Notice does not resign within thirty (30) days from receipt thereof by such Director, the Mainsail Related Parties and the Just Rocks Related Parties, as holders of
Class A Common Stock, Class B Common Stock, Class C Common Stock and Class D Common Stock, the Corporation and the Board, to the fullest extent permitted by law and, with respect to the Board, subject to its fiduciary duties to
the Corporation’s stockholders, shall thereafter take all Necessary Action, including voting in accordance with Section 1(c) to cause the removal of such Director from the Board. 

(c) Except with respect to a Decrease in Designation Rights subject to Section 2(a), each of the Mainsail Related

with outside legal counsel, that its nomination, appointment or election of a particular Director designated in accordance with Section 1 or Section 2, as applicable, would constitute a breach of
its fiduciary duties to the Corporation’s stockholders or does not otherwise comply with any requirements of the Charter or Bylaws and Securities Laws, then the Board shall inform the Mainsail Related Parties and/or the Just Rocks Related
Parties, as applicable, of such determination in writing and explain in reasonable detail the basis for such determination and shall, to the fullest extent permitted by law, nominate, appoint or elect another individual designated for nomination,
election or appointment to the Board by the Mainsail Related Parties and/or the Just Rocks Related Parties, as applicable (subject in each case to this Section 4(b)). The Board and the Corporation shall, to the fullest extent permitted by law,

a result of the Corporation’s investment in Brilliant Earth, LLC or (ii) re-investing cash into Brilliant Earth, LLC (whether by way of intercompany loan, investment or otherwise).

the time owned or controlled, directly or indirectly, by the Corporation, or (ii) if a limited liability company, partnership, association or other business entity, either (x) a majority of the Capital Stock of such Person entitled

indirectly, by the Corporation or (y) the Corporation or one of its Subsidiaries is the sole manager or general partner of such Person.  

Section 2. Demand Registrations. 

(a) At any time 180 days after the date when any of the Class A Common Stock is registered under the Securities Act, if any Holder
requests the Company to file a registration statement under the Securities Act for a firm commitment underwritten public offering of not less than 20% of the Registrable Securities (or any lesser percentage if the anticipated aggregate offering
price of such offering, net of underwriting discounts and commissions, exceeds $15,000,000), the Company shall (A) within 10 days notify all Holders of such request, and (B) use its commercially reasonable efforts to so register under the
Securities Act the Registrable Securities initially requested to be registered and the Registrable Securities of all other Holders who request within 10 days after receiving the Company’s notice that their Registrable Securities be included
therein. The Company shall not be obligated to effect more than two such demand registrations requested by the Holders.  

(b) If the underwriter managing the offering determines that, because of marketing considerations, not all of the Registrable Securities
requested to be registered may be included in the offering, then all Holders who have requested registration in the offering shall have their Registrable Securities reduced pro rata based upon the number of Registrable Securities that they have
requested to be so registered. 

  
 4 

 (c) If the Company includes in any registration required under this Section 2 a number
of shares other than Registrable Securities that exceeds the number of Registrable Securities to be included, then such registration shall be deemed to be a registration under Section 3 instead of this Section 2. In all other cases where
the Company includes in such registration any shares other than Registrable Securities, such registration shall remain subject to this Section 2, provided that in no event shall other shares be included if such inclusion would
(A) prevent Holders from registering all Registrable Securities requested by them, or (B) adversely affect the offering price of the Registrable Securities in such registration. 

Section 3. Piggyback Registrations. 

(a) Whenever the Company proposes to register any Class A Common Stock for its own or others’ account under the Securities Act,
other than a registration relating to employee benefit plans or a registration solely relating to shares to be sold under Rule 145 or a similar provision under the Securities Act or a demand registration under Section 2, the Company shall give
each Holder prompt written notice of its intent to do so. Upon the written request of any Holder given within 10 days after receipt of such notice, the Company will use its best efforts to cause to be included in such registration all of the
Registrable Securities that such Holder requests; provided that the Company shall have the right to postpone, delay or cancel any registration made under this Section 3.  

(b) If the Company is advised in writing in good faith by any managing underwriter of the securities being offered pursuant to any
registration statement under this Section 3 that, because of marketing considerations, the number of shares to be sold by Persons other than the Company is greater than the number of such shares that can be offered without adversely affecting
the offering, the Company may reduce pro rata the number of shares offered for the accounts of such Persons (based upon the number of shares requested by each such Person to be included in the registration) to a number deemed satisfactory by such
managing underwriter. Such pro rata reduction shall be applied first, to shares held by such Persons other than Registrable Securities, which shares will not be included in the registration unless all Registrable Securities requested to be included
in the registration have been included, and second, pro rata among the Registrable Securities requested to be included in the registration. 

Section 4. Form S-3 Registration Rights. If, at a time when
Form S-3 (or any successor form) is available for such registration, the Company shall receive from any Holder a written request or requests that the Company effect a registration on Form S-3 (or any successor form) of any of such Holder’s Registrable Securities, the Company will promptly give written notice of the proposed registration to all other Holders and, as soon as practicable,
use its commercially reasonable efforts to effect such registration and all related qualifications and compliances as may be requested and as would permit or facilitate the sale and distribution of all Registrable Securities as are specified in such
request and any written requests of other Holders given within 10 days after receipt of such notice. The Company shall have no obligation to effect a registration under this Section 4 unless the aggregate offering price of the Registrable
Securities requested to be sold pursuant to such registration is expected to be equal to or greater than $5,000,000. Any registration under this Section 4 will not be counted as a registration under Section 2 above. 

  
 5 

 Section 5. Selection of Underwriter. The underwriter of any offering under
Section 5(a) shall be selected by agreement of the Holders of a majority of the Registrable Securities initiating such registration, provided that such underwriter shall be reasonably acceptable to the Company. The underwriter of any
offering requested under Section 5(b) shall be selected by the Company. 
 Section 6. Registration Procedures. If and
whenever the Company is required by the provisions of this Agreement to use its commercially reasonable efforts to effect the registration of any of the Registrable Securities under the Securities Act, the Company shall: 

(a) as expeditiously as reasonably possible file with the Securities and Exchange Commission (the “Commission”) a
registration statement, in form and substance required by the Securities Act, with respect to such Registrable Securities and use its commercially reasonable efforts to cause that registration statement to become effective; 

(b) as expeditiously as possible, prepare and file with the Commission any amendments and supplements to the registration statement and the
prospectus included in the registration statement as may be necessary to keep the registration statement effective, in the case of a firm commitment underwritten public offering, until completion of the distribution of all securities described
therein and, in the case of any other offering, until the earlier of (i) the sale of all Registrable Securities covered thereby or (ii) 120 days after the effective date thereof; 

(c) as expeditiously as possible, furnish to each Holder that requested that Registrable Securities be included in such registration, such
reasonable numbers of copies of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Holder may reasonably request in order to facilitate the public sale or
other disposition of the Registrable Securities owned by such Holder; 
 (d) as expeditiously as possible, use its commercially reasonable
efforts to register or qualify the Registrable Securities covered by the registration statement under the securities or Blue Sky laws of such states as the Holders thereof shall reasonably request, and do any and all other acts and things that may
be necessary or desirable to enable the Holders thereof to consummate the public sale or other disposition in such states as are reasonably requested by such Holders; provided, however, that the Company shall not be required in
connection with this paragraph (iv) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction; 

(e) in connection with each registration covering an underwritten public offering, enter (and each participating Holder agrees to enter) into
a written agreement with the managing underwriter in such form and containing such provisions (including, if the underwriter so requests, customary contribution provisions on the part of the Company) as are customary in the securities business for
such an arrangement between such underwriter and companies of the Company’s size and investment stature, provided that the Holders shall not be obligated to enter into any such underwriting agreement if the indemnification provisions
thereof are materially more burdensome on such Holder than those contained herein or if any standback requirement therein is for a period that materially exceeds the period required by this Agreement; 

  
 6 

 (f) at the request of any participating Holder, furnish to each underwriter, if any, and the
participating Holders, a legal opinion of its counsel and a letter from its independent certified public accountants, each in customary form and substance, at such time or times as such documents are customarily provided in the type of offering
involved; 
 (g) whenever the Company is registering any Class A Common Stock under the Securities Act and a Holder is selling
securities under such registration or determines that it may be a controlling person under the Securities Act, keep such Holder advised of the initiation, progress and completion of such registration, allow such Holder and such Holder’s counsel
to participate in the preparation of the registration statement and to have access to all relevant corporate records, documents and information, and take all such other action as such Holder may reasonably request; 

(h) as of the effective date of any registration statement relating thereto, cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then listed, and, if not so listed, to be listed on the New York Stock Exchange or the Nasdaq Global Market; and 

(i) as of the effective date of any registration statement relating thereto, provide a transfer agent and registrar for all such Registrable
Securities. 
 Each Holder of Registrable Securities included in a registration shall furnish to the Company such information regarding such
Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be required in connection with the registration, qualification or compliance contemplated by this Agreement. 

Section 7. Registration Expenses. The Company will pay all expenses incurred in connection with any registration pursuant to this
Agreement, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, transfer taxes, fees and expenses of counsel for the Company and the reasonable fees and expenses of one counsel selected by the
Holders of a majority of the Registrable Securities to be included in such registration to represent them, state securities or Blue Sky fees and expenses, and the expense of any special audits incident to or required by any such registration, but
excluding underwriting discounts and selling commissions relating to the sale of the Registrable Securities. 
 Section 8.
Notification. The Company shall promptly notify each Holder of Registrable Securities covered by any registration statement of any event that results in the prospectus included in such registration statement or such registration statement, as
then in effect, containing an untrue statement of a material fact or omitting to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. 

  
 7 

 Section 9. Indemnification and Contribution. 

(a) Indemnification by the Company. The Company shall indemnify and hold harmless each Holder included in any registration, its
officers, directors, managers, members, partners and Affiliates, each underwriter of the Registrable Securities being sold by such Holder, and each controlling person of any of the foregoing, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering, circular, or other document relating to such Registrable Securities (or in any
related registration statement, notification or the like) or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act, the Exchange Act, or any other law, rule or regulation applicable to the Company and relating to action or inaction required of the Company in connection with any registration, qualification or compliance contemplated
by this Agreement, and will reimburse each such Holder, each of its officers, directors, managers, members, partners and affiliates, and each such underwriter and controlling person for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage, liability or action, whether or not resulting in liability: provided, however, that (A) the indemnity agreement contained in this Section 9(a) shall not
apply to amounts paid in settlement of any such claim, loss, damage, liability, action or proceeding if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld) except that no such consent
shall be required if the settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to, or an admission
of, fault, culpability or a failure to act by or on behalf of any indemnified party, and (B) the Company will not be liable in any such case to the extent that any such claim, loss, damage or liability (i) arises out of or is based on any
untrue statement or omission based upon and in conformity with written information furnished to the Company by or on behalf of such Holder or underwriter and stated to be specifically for use therein, or (ii) results solely from the failure of
such Holder to deliver a copy of the registration statement, prospectus, offering circular or any amendments or supplements thereto after the Company has furnished such Holder with a sufficient number of copies thereof. 

(b) Indemnification by the Holders of Registrable Securities. Each participating Holder shall, severally and not jointly, indemnify and
hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each underwriter of the Registrable Securities, each other participating Holder, its officers, directors, managers, members, partners
and affiliates, and each controlling person of any of the foregoing, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact
concerning such Holder contained in any prospectus, offering circular or other document relating to the Registrable Securities (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state
therein a material fact concerning such Holder required to be stated therein or necessary to make the statements therein concerning such Holder not misleading, and will reimburse the Company and each such director, officer, manager, member, other
participating Holder, partner, affiliate or 

  
 8 

 
controlling person referred to above for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action;
provided, however, that no Holder will be liable in any such case except to the extent that any such claim, loss, damage or liability arises out of any untrue statement or omission based upon and in conformity with written information
furnished to the Company by or on behalf of such Holder and stated to be specifically for use therein; and provided, further, that no Holder will be liable under this Section for losses, costs, damages or expenses exceeding in the
aggregate the net proceeds paid to such Holder in such offering. 
 (c) Procedures for Indemnification. Each party entitled to
indemnification under Sections 9(a) or (b) (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party; and, provided, further, that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Agreement. The Indemnified Party may participate in such defense at such party’s expense; provided, however, that the Indemnifying Party shall pay such
expenses if the Indemnified Party shall believe in good faith that representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the
Indemnified Party and any other party represented by such counsel in such proceeding. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or
enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld, delayed or conditioned. 

(d) Contribution. If the indemnification provided for in Sections 9(a) or (b) is unavailable to any Indemnified Party
thereunder in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to in such Sections, then each Person that would have been an Indemnifying Party thereunder shall contribute to the amount paid or payable
by such Indemnified Party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and such Indemnified
Party on the other. The relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or such Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, or whether such losses, claims, damages or
liabilities (or actions in respect thereof) arose out of the action or failure to act of one or more of such parties. Notwithstanding the foregoing, (A) no Holder will be required to contribute any amount in excess of the net proceeds paid to
such Holder in respect of all Registrable Securities sold by such Holder pursuant to such registration statement, and (B) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

  
 9 

 Section 10. Reports Under Exchange Act. With a view to making available to the
Holders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a
registration on Form S-3 (or any successor form), the Company agrees to use its commercially reasonable efforts to satisfy the requirements of all such rules and regulations (including the requirements for
public information, registration under the Exchange Act and timely reporting to the Commission) at the earliest possible date (but in any event not later than 90 days) after the effective date of the registration statement for its first registered
public offering. The Company will furnish to each Holder, whenever requested, a written statement as to its compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, a copy of its most recent annual or
quarterly report, and such other reports and information filed by the Company as such Holder may reasonably request in connection with the sale of Registrable Securities without registration. 

Section 11. Registration Rights of Others. The Company will not, without the prior written consent of the Holders of a majority of
the Registrable Securities, grant to any other Person the right to (a) require the Company to initiate the registration of any securities, or (b) require the Company to include in any registration securities owned by such Person, unless
under the terms of such arrangement such Person may include securities in such registration only to the extent that the inclusion thereof does not limit the number of Registrable Securities included therein or adversely affect the offering price
thereof. The Company represents and warrants that it has not granted any Person other than the parties hereto the right to require the Company to initiate the registration of any securities or include in any registration any securities owned by such
Person. 
 Section 12. Lock-Up Agreement. Each Holder agrees that, in connection with
any public offering of Class A Common Stock, and upon the request of the managing underwriter in such offering, such Holder will not offer, transfer, sell, contract to sell, grant any option or right for the purchase of, or otherwise dispose of
any of the Company’s or any successor’s or parent’s securities held by such Holder (other than those included in such registration), or engage in any swap or derivative transactions involving any such securities, in each case, without
the prior written consent of such underwriter, for such period of time as may be requested by such underwriter (commencing as of the date of such public offering and ending no later than (b) 90 days after the effective date of such registration).

 Section 13. Black-Out Periods. Notwithstanding anything in this Section 5 to the
contrary, if the Company shall furnish to the Holders initiating a registration pursuant to Section 5(a) or Section 5(c) of this Agreement a certificate signed by the President or Chief Executive Officer of the Company stating that the
Board has made the good faith determination (after consultation with counsel) (i) that use by the Holders of such proposed registration statement for purposes of effecting offers or sales of Registrable Securities pursuant thereto would
require, under the Securities Act, premature disclosure in such registration statement of material, nonpublic information concerning any proposed material transaction involving the Company; (ii) that such premature disclosure would be
materially adverse to the Company or such proposed material transaction or would make the successful consummation by the Company of any such material

transaction significantly less likely; and (iii) that it is therefore essential to defer the filing of such registration statement for purposes of effecting offers or sales of Registrable
Securities pursuant thereto, then the right of the Holders to require the Company to file such registration statement for purposes of effecting offers or sales of Registrable Securities pursuant thereto shall be suspended for a period (the
“Black Out Period”) of not more than 60 days after delivery by the Company of the certificate referred to above. Notwithstanding the foregoing, (A) if the public announcement of such material transaction is made during a

 Section 14. General Provisions. 

(a) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified, terminated
or waived only with the prior written consent of the Corporation and the Holders of a majority of the Registrable Securities; provided that no such amendment, modification, termination or waiver that would materially and adversely affect a
Holder in a manner materially different than any other Holder, shall be effective against such Holder without the consent of such Holder that is materially and adversely affected thereby. The failure or delay of any Person to enforce any of the
provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent
to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person
of the same or any other obligations of that Person under this Agreement. 
 (b) Remedies. The parties to this Agreement shall be
entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their
favor. The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing
hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the
provisions of this Agreement. 
 (c) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition,
invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and
enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein. 

  
 11 

 (d) Entire Agreement. Except as otherwise provided herein, this Agreement contains
the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which

of this Agreement which are for the benefit Holders are also for the benefit of, and enforceable by, any subsequent or successor Holder.
