On the date hereof, the Company is a holding company which currently holds no material assets, other than an equity interest in SDC Financial LLC, a Delaware limited lability company (“SDC LLC”), and does not engage in any operations.

The Company and SDC LLC are collectively referred to herein as the “SDC Parties.”

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-267370) (the “registration statement”) for the registration of the Shares and other securities of the Company under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”); and such registration statement sets forth the terms of the offering, sale and plan of distribution of the Shares and contains additional information concerning the Company and its business. Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Agent, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein and (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the effective time. “Basic Prospectus” means the prospectus dated October 4, 2022 filed as part of the Registration Statement, including the documents incorporated by reference therein as of the date of such prospectus; “Prospectus Supplement” means the most recent prospectus supplement relating to the Shares, to be filed by the Company with the Commission pursuant to Rule 424(b) under the Act on or before the

Any reference herein to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall, unless otherwise stated, be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall, unless stated otherwise, be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”) on or after the initial effective date of the Registration Statement, or the date of the Basic Prospectus, the Prospectus Supplement, the Prospectus or such Permitted Free Writing Prospectus, as the case may be, and deemed to be incorporated therein by reference.

The Company and the Agent agree as follows:

1. Issuance and Sale.

(b) Subject to the terms and conditions set forth below, the Company appoints the Agent as agent in connection with the offer and sale of Shares in any Agency Transactions entered into hereunder. The Agent will use commercially reasonable efforts, consistent with its normal trading and sales practices, to sell such Shares in accordance with the terms and subject to the conditions hereof and of the applicable Transaction Acceptance (as defined below). Neither the Company nor the Agent shall have any obligation to enter into an Agency Transaction. The Company shall be obligated to issue and sell through the Agent, and the Agent shall be obligated to use commercially reasonable efforts, consistent with its normal trading and sales practices and as provided herein and in the applicable Transaction Acceptance, to place Shares only if and when the Company makes a Transaction Proposal (as defined below) to the Agent related to such an Agency Transaction and a Transaction Acceptance related to such Agency Transaction has been delivered to the Company by the Agent as provided in Section 2 below.

(c) The Agent, as agent in any Agency Transaction, hereby covenants and agrees not to make any sales of the Shares on behalf of the Company pursuant to this Agreement other than (A) by means of ordinary brokers’ transactions between members of the Exchange that qualify for delivery of a Prospectus in accordance with Rule 153 under the Act and meet the definition of an “at the market offering” under Rule 415(a)(4) under the Act (such transactions are hereinafter referred to as “At the Market Offerings”) and (B) such other sales of the Shares on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and the Agent in writing.

(d) If Shares are to be sold in an Agency Transaction in an At the Market Offering, the Agent will confirm in writing to the Company the number of Shares sold on any Exchange Business Day and the related Gross Sales Price and Net Sales Price (as each of such terms is defined in Section 2(b) below) no later than the opening of trading on the immediately following Exchange Business Day.

(e) If the Company shall default on its obligation to deliver Shares to the Agent pursuant to the terms of any Agency Transaction or Terms Agreement, the Company shall (i) indemnify and hold harmless the Agent and its successors and assigns from and against any and all losses, claims, damages, liabilities and expenses arising from or as a result of such default by the Company and (ii) notwithstanding any such default, pay to the Agent the commission to which it would otherwise be entitled in connection with such sale in accordance with Section 2(b) below.

(f) The Company acknowledges and agrees that (i) there can be no assurance that the Agent will be successful in selling the Shares, (ii) the Agent shall incur no liability or obligation to the Company or any other person or entity if it does not sell Shares for any reason other than a failure by the Agent to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Shares in accordance with the terms of this Agreement, and (iii) the Agent shall be under no obligation to purchase Shares on a principal basis pursuant to this Agreement, except as may otherwise be specifically agreed by the Agent and the Company in a Terms Agreement.

2. Transaction Acceptances and Terms Agreements.

(a) The Company may, from time to time during the Term, propose to the Agent that they enter into an Agency Transaction to be executed on a specified Exchange Business Day or over a specified period of Exchange Business Days, which proposal shall be made to the Agent by telephone or by email from any of the individuals listed as an authorized representative of the Company on Schedule A hereto to make such sales and shall set forth the information specified below (each, a “Transaction Proposal”). If the Agent agrees to the terms of such proposed Agency Transaction or if the Company and the Agent mutually agree to modified terms for such proposed Agency Transaction, then the Agent shall promptly deliver to the Company by email a notice (each, a “Transaction Acceptance”) confirming the terms of such proposed Agency Transaction as set forth in such Transaction Proposal or setting forth the modified terms for such proposed Agency Transaction as agreed by the Company and the Agent, as the case may be, whereupon such Agency Transaction shall become a binding agreement between the Company and the Agent. Each Transaction Proposal shall specify:

A Transaction Proposal shall not set forth an amount of Specified Shares that, when the Gross Sales Price of such Specified Shares is added to the aggregate Gross Sales Price of Shares previously purchased and to be purchased pursuant to pending Transaction Acceptances (if any) hereunder and any Terms Agreements, results or could result in a total that exceeds the Maximum Amount nor shall it set forth a Floor Price which is lower than the minimum price authorized from time to time by the Company’s board of directors or, if permitted by applicable law and the Company’s charter and by-laws, a duly authorized committee thereof. The Company shall have responsibility for maintaining records with respect to the aggregate number and aggregate Gross Sales Price of Shares sold and for otherwise monitoring the availability of Shares for sale under the Registration Statement and for insuring that the aggregate number and aggregate Gross Sales Price of Shares offered and sold does not exceed, and the price at which any Shares are offered or sold is not lower than, the aggregate number and aggregate Gross Sales Price of Shares and the minimum price

4

authorized from time to time by the Company’s board of directors or, if permitted by applicable law and the Company’s charter and by-laws, a duly authorized committee thereof. In the event that more than one Transaction Acceptance with respect to any Purchase Date(s) is delivered by the Agent to the Company, the latest Transaction Acceptance shall govern any sales of Shares for the relevant Purchase Date(s), except to the extent of any action occurring pursuant to a prior Transaction Acceptance and prior to the delivery to the Company of the latest Transaction Acceptance. The Company or the Agent may, upon notice to the other such party by telephone (confirmed promptly by e-mail), suspend or terminate the offering of the Shares pursuant to Agency Transactions for any reason; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice or their respective obligations under any Terms Agreement. Notwithstanding the foregoing, if the terms of any Agency Transaction contemplate that Shares shall be sold on more than one Purchase Date, then the Company and the Agent shall mutually agree to such additional terms and conditions as they deem reasonably necessary in respect of such multiple Purchase Dates, and such additional terms and conditions shall be set forth in or confirmed by, as the case may be, the relevant Transaction Acceptance and be binding to the same extent as any other terms contained therein.

(b) The Purchase Date(s) in respect of the Shares deliverable pursuant to any Transaction Acceptance shall be set forth in or confirmed by, as the case may be, the applicable Transaction Acceptance. Except as otherwise agreed between the Company and the Agent, the Agent’s commission for any Shares sold through the Agent pursuant to this Agreement shall be 2.50%, of the actual sales price of such Shares (the “Gross Sales Price”), which commission shall be as set forth in or confirmed by, as the case may be, the applicable Transaction Acceptance; provided, however, that such commission shall not apply when the Agent acts as principal, in which case such commission or a discount shall be set forth in the applicable Terms Agreement. Notwithstanding the foregoing, in the event the Company engages the Agent for a sale of Shares in an Agency Transaction that would constitute a “distribution,” within the meaning of Rule 100 of Regulation M under the Exchange Act or a “block” within the meaning of Rule 10b-18(a)(5) under the Exchange Act, the Company will provide the Agent, at the Agent’s request and upon reasonable advance notice to the Company, on or prior to the Agency Settlement Date (as defined below) the opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 5 hereof, each dated the Agency Settlement Date, and such other documents and information as the Agent shall reasonably request, and the Company and the Agent will agree to compensation that is customary for the Agent with respect to such transaction. The Gross Sales Price less the Agent’s commission and after deduction for any transaction fees, transfer taxes or similar taxes or fees imposed by any governmental, regulatory or self-regulatory organization in respect of the sale of the applicable Shares is referred to herein at the “Net Sales Price.”

5

(c) Payment of the Net Sales Price for Shares sold by the Company on any Purchase Date pursuant to a Transaction Acceptance shall be made to the Company by wire transfer of immediately available funds to the account of the Company (which the Company shall provide to the Agent at least one Exchange Business Day prior to the applicable Agency Settlement Date) against delivery of such Shares to the Agent’s account, or an account of the Agent’s designee, at The Depository Trust Company through its Deposit and Withdrawal at Custodian System (“DWAC”) or by such other means of delivery as may be agreed to by the Company and the Agent. Such payment and delivery shall be made at or about 12:00 p.m. (New York City time) on the second Exchange Business Day (or such other day as may, from time to time, become standard industry practice for settlement of such a securities issuance or as agreed to by the Company and the Agent) following each Purchase Date (each, an “Agency Settlement Date”).

(d) If, as set forth in or confirmed by, as the case may be, the related Transaction Acceptance, a Floor Price has been agreed to by the parties with respect to a Purchase Date, and the Agent thereafter determines and notifies the Company that the Gross Sales Price for such Agency Transaction would not be at least equal to such Floor Price, then the Company shall not be obligated to issue and sell through the Agent, and the Agent shall not be obligated to place, the Shares proposed to be sold pursuant to such Agency Transaction on such Purchase Date, unless the Company and the Agent otherwise agree in writing.

(e) If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Shares, it shall promptly notify the other party and sales of the Shares under this Agreement, any Transaction Acceptance or any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party. On or prior to the delivery of a prospectus that is required (whether physically or through compliance with Rule 172 under the Act or any similar rule) in connection with the offering or sale of the Shares, the Company shall calculate the average daily trading volume (as defined under “ADTV” by Rule 100 of Regulation M under the Exchange Act) of the Common Stock based on market data provided by Bloomberg L.P. or such other sources as agreed upon by the Company and the Agent.

6

(g) Each sale of the Shares to the Agent in a Principal Transaction shall be made in accordance with the terms of this Agreement and a Terms Agreement, which shall provide for the sale of such Shares to, and the purchase thereof by, the Agent. A Terms Agreement may also specify certain provisions relating to the reoffering of such Shares by the Agent. The commitment of the Agent to purchase the Shares pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations, warranties and agreements of the Company contained, and shall be subject to the terms and conditions set forth, in this Agreement and such Terms Agreement. Any such Terms Agreement shall specify the number of the Shares to be purchased by the Agent pursuant thereto, the price to be paid to the Company for such Shares, any provisions relating to rights of, and default by, underwriters, if any, acting together with the Agent in the reoffering of the Shares, and the time and date (each such time and date being referred to herein as a “Principal Settlement Date”; and, together with any Agency Settlement Date, a “Settlement Date”) and place of delivery of and payment for such Shares.

(h) Notwithstanding any other provision of this Agreement, the Company shall not offer, sell or deliver, or request the offer or sale, of any Shares pursuant to this Agreement (whether in an Agency Transaction or a Principal Transaction) and, by notice to the Agent given by telephone (confirmed promptly by email), shall cancel any instructions for the offer or sale of any Shares, and the Agent shall not be obligated to offer or sell any Shares, (i) during any period in which the Company is, or could be deemed to be, in possession of material non-public information or (ii) at any time from and including the date on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (an “Earnings Announcement”) through the later of: (a) the time that the Company files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement and (b) the completion of a teleconference, webcast or similar oral presentation of the information covered by such Earnings Announcement.

(i) The Company agrees that any offer to sell, any solicitation of an offer to buy, or any sales of Shares by the Company shall be effected only by or through the Agent on any Exchange Business Day.

(j) Anything in this Agreement to the contrary notwithstanding, the Company shall not authorize the issuance and sale of, and the Agent, as sales agent, shall not be obligated to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to sell, any Shares at a price lower than the minimum price, or in a number or with an aggregate gross or net sales price in excess of the number or aggregate gross or net sales price, as the case may be, authorized from time to time to be issued and sold under this Agreement and any Terms Agreement, in each case by the Company’s board of directors or, if permitted by applicable law and the Company’s charter and by-laws, a duly authorized committee thereof, or in a number in excess of the number of Shares approved for listing on the Exchange, or in excess of the number or amount of Shares available for issuance on the Registration Statement or as to which the Company has paid the applicable registration fee, it being understood and agreed by the parties hereto that compliance with any such limitations shall be the sole responsibility of the Company.

(b) The Agent shall have received a letter or letters, which shall include legal opinions and negative assurance statements, of Latham & Watkins LLP, counsel to the Agent, addressed to the Agent and dated the date of this Agreement, addressing such matters as the Agent may reasonably request.

6. Additional Covenants of the Company. The Company further covenants and agrees with the Agent as follows:

(a) Each Transaction Proposal made by the Company that is accepted by the Agent by means of a Transaction Acceptance and each execution and delivery by the Company of a Terms Agreement shall be deemed to be (i) an affirmation that the representations, warranties and agreements of the SDC Parties herein contained and contained in any certificate delivered to the Agent pursuant hereto are true and correct at such Time of Acceptance or the date of such Terms Agreement, as the case may be, and (ii) an undertaking that such representations, warranties and agreements will be true and correct on any applicable Time of Sale and Settlement Date, as though made at and as of each such time (it being understood that such representations, warranties and agreements shall relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of such Transaction Acceptance or Terms Agreement, as the case may be).

(b) Each time that (i) the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus shall be amended or supplemented (including, except as noted in the proviso at the end of this Section 6(b), by the filing of any Incorporated Document), (ii) there is a Principal Settlement Date pursuant to a Terms Agreement, or (iii) the Agent shall reasonably request (each date referred to clauses (i), (ii) and (iii) above, a “Bring-Down Delivery Date”), the Company shall, unless the Agent agrees otherwise, furnish or cause to be furnished to the Agent certificates, dated as of such Bring-Down Delivery Date and delivered within one Exchange Business Day after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, delivered on such Principal Settlement Date, of the same tenor as the certificates referred to in Sections 5(a)(i) and 5(a)(iv) hereof, modified as necessary to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such certificates and, in the case of the Chief Financial Officer’s certificate, covering such other financial, numerical and statistical data that is not covered by the accountants’ “comfort” letter dated as of such Bring-Down Delivery Date as the Agent may reasonably request, or, in lieu of such certificates, certificates to the effect that the statements contained in the certificates referred to in Sections 5(a)(i) and, unless the Agent shall have requested that the Chief Financial Officers’ certificate cover different or additional data as aforesaid, 5(a)(iv) hereof furnished to Agent are true and correct as of such Bring-Down Delivery Date as though made at and as of such date (except that such statements shall be deemed to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such certificate); provided, however, that the filing of a Current Report on Form 8-K will not constitute a Bring-Down Delivery Date under clause (i) above unless either (A) (x) such Current Report on Form 8-K is filed at any time during which either a Transaction Acceptance is binding and the Company has not suspended the use thereof (and prior to the

28

settlement of the Shares specified therein) or a prospectus relating to the Shares is required to be delivered under the Act (whether physically or through compliance with Rule 172 under the Act or any similar rule) or such Current Report on Form 8-K is filed at any time from and including the date of a Terms Agreement through and including the related Settlement Date and (y) the Agent has reasonably requested that such date be deemed to be a Bring-Down Delivery Date based upon the event or events reported in such Current Report on Form 8-K or (B) such Current Report on Form 8-K contains capsule financial information, historical or pro forma financial statements, supporting schedules or other financial data, including any Current Report on Form 8-K or part thereof under Item 2.02 of Regulation S-K of the Commission that is considered “filed” under the Exchange Act; and provided, further, that an amendment or supplement to the Registration Statement or the Prospectus relating to the offering of other securities pursuant to the Registration Statement will not constitute a Bring-Down Delivery Date.

(c) Each Bring-Down Delivery Date, the Agent, unless it agrees otherwise, shall have received (A) the written opinion and, if not included in such opinion, negative assurance letter of Foley & Lardner LLP, counsel to the Company and (B) the written opinion and, if not included in such opinion, negative assurance letter of Latham & Watkins LLP, counsel to the Agents, each dated as of the applicable Bring-Down Delivery Date and delivered within one Exchange Business Day after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, dated and delivered on such Principal Settlement Date, of the same tenor as the opinions and letters referred to in Section 5(a)(ii) or Section 5(b) hereof, as applicable, but modified as necessary to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such opinions and letters, or, in lieu of such opinions and letters, each such counsel shall furnish the Agent with a letter substantially to the effect that the Agent may rely on the opinion and letter of such counsel referred to in Section 5(a)(ii) or Section 5(b), as applicable, furnished to the Agent, to the same extent as though they were dated the date of such letter authorizing reliance (except that statements in such last opinion and letter of such counsel shall be deemed to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such letters authorizing reliance).

(d) Each Bring-Down Delivery Date, the Agent shall have received from Ernst & Young LLP a “comfort” letter, dated as of the applicable Bring-Down Delivery Date and delivered within one Exchange Business Day after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, delivered on such Principal Settlement Date, of the same tenor as the letter referred to in Section 5(a)(iii) hereof, but modified to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the date of such letter, and, if the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus shall include or incorporate by reference the financial statements of any entity or business (other than the consolidated financial statements of the Company and its subsidiaries), the Company shall, if requested by the Agent, cause a firm of independent public accountants to furnish to the Agent a “comfort” letter, dated as of the applicable Bring-Down Delivery Date and delivered within one Exchange Business Day after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, delivered on such Principal Settlement Date, addressing such matters as the Agent may reasonably request.

29

(e) The requirement to provide the certificates, legal opinions and comfort letter under Sections 6(b) through (d) shall be waived for any Bring-Down Delivery Date occurring at a time when no Transaction Acceptance or Terms Agreement is pending or a suspension is in effect, which waiver shall continue until the earlier to occur of the date the Company delivers instructions for the sale of Shares hereunder (which for such calendar quarter shall be considered a Bring-Down Delivery Date) and the next occurring Bring-Down Delivery Date. Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following a Bring-Down Delivery Date when a suspension was in effect and did not provide the Agent with the certificates, legal opinions and comfort letter under Sections 6(b) through (d) then before the Company delivers the instructions for the sale of Shares or the Agent sells any Shares pursuant to such instructions, the Company shall provide the Agent with such certificates, legal opinions and comfort letter in conformity with Sections 6(b) through (d), dated as of the date that the instructions for the sale of Shares are issued.

(f) (i) No order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose or pursuant to Section 8A under the Act shall be pending before or threatened by the Commission; the Prospectus and each Permitted Free Writing Prospectus shall have been timely filed with the Commission under the Act (in the case of a Permitted Free Writing Prospectus, to the extent required by Rule 433 under the Act); and all requests by the Commission for additional information shall have been complied with to the satisfaction of the Agent and no suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes, shall have occurred and be in effect at the time the Company delivers a Transaction Proposal to the Agent or the time the Agent delivers a Transaction Acceptance to the Company; and (ii) the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus shall not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading at the time the Company delivers a Transaction Proposal to the Agent or the time the Agent delivers a Transaction Acceptance to the Company.

(g) The Company shall reasonably cooperate with any reasonable due diligence review requested by the Agent or its counsel from time to time in connection with the transactions contemplated hereby or any Terms Agreement, including, without limitation, (i) at the commencement of each intended Purchase Date and any Time of Sale or Settlement Date, providing information and making available appropriate documents and appropriate corporate officers of the Company and, upon reasonable request, representatives of Ernst & Young LLP (and, if the Registration Statement, the Prospectus or any Permitted Free-Writing Prospectus shall include or incorporate by reference the financial statements of any entity or business (other than the consolidated financial statements of the Company and its subsidiaries), representatives of the independent public accountants that audited or reviewed such financial statements) for an update on diligence matters with representatives of the Agent and (ii) at each Bring-Down Delivery Date and otherwise as the Agent may reasonably request, providing information and making available documents and appropriate corporate officers of the Company and

30

representatives of Ernst & Young LLP (and, if the Registration Statement, the Prospectus or any Permitted Free-Writing Prospectus shall include or incorporate by reference the financial statements of any entity or business (other than the consolidated financial statements of the Company and its subsidiaries), representatives of the independent public accountants that audited or reviewed such financial statements) for one or more due diligence sessions with representatives of the Agent and its counsel.

(h) The Company shall disclose, in its quarterly reports on Form 10-Q and in its annual report on Form 10-K and, if requested by the Agent, in supplements to the Prospectus to be filed by the Company with the Commission from time to time, the number of the Shares sold through the Agent under this Agreement and any Terms Agreement, and the gross and net proceeds to the Company from the sale of the Shares and the compensation paid by the Company with respect to sales of the Shares pursuant to this Agreement during the relevant quarter or, in the case of any such prospectus supplement, such shorter period as the Agent may reasonably request or, in the case of an Annual Report on Form 10-K, during the fiscal year covered by such Annual Report and the fourth quarter of such fiscal year.

All opinions, letters and other documents referred to in Sections 6(b) through (d) above shall be reasonably satisfactory in form and substance to the Agent. The Agent will provide the Company with such notice (which may be oral, and in such case, will be confirmed via e-mail as soon as reasonably practicable thereafter) as is reasonably practicable under the circumstances when requesting an opinion, letter or other document referred to in Sections 6(b) through (d) above.

7. Conditions of the Agent’s Obligation. The Agent’s obligation to solicit purchases on an agency basis for the Shares or otherwise take any action pursuant to a Transaction Acceptance and to purchase the Shares pursuant to any Terms Agreement shall be subject to the satisfaction of the following conditions:

(a) At the Time of Acceptance, at the time of the commencement of trading on the Exchange on the Purchase Date(s) and at the relevant Time of Sale and Agency Settlement Date, or with respect to a Principal Transaction pursuant to a Terms Agreement, at the time of execution and delivery of the Terms Agreement by the Company and at the relevant Time of Sale and Principal Settlement Date:

31

32

(b) Within one Exchange Business Day after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, on such Principal Settlement Date, the Agent shall have received the officer’s certificates, opinions and negative assurance letters of counsel and “comfort” letters and other documents provided for under Sections 6(b) through (d), inclusive. For purposes of clarity and without limitation to any other provision of this Section 7 or elsewhere in this Agreement, the parties hereto agree that the Agent’s obligations, if any, to solicit purchases of Shares on an agency basis or otherwise take any action pursuant to a Transaction Acceptance shall, unless otherwise agreed in writing by the Agent, be suspended during the period from and including a Bring-Down Delivery Date through and including the time that the Agent shall have received the documents described in the preceding sentence.

8. Termination.

33

(c) This Agreement shall remain in full force and effect until the earliest of (A) termination of the Agreement pursuant to Section 8(a) or 8(b) above or otherwise by mutual written agreement of the parties, (B) such date that the Maximum Amount of Shares has been sold in accordance with the terms of this Agreement and any Terms Agreements and (C) the third anniversary of the date of this Agreement, in each case except that the provisions of Section 3, 4 (except that if no Shares have been previously sold hereunder or under any Terms Agreement, only Section 4(l)), 9, 13, 14 and 16 of this Agreement shall remain in full force and effect notwithstanding such termination.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that, notwithstanding the foregoing, such termination shall not be effective until the close of business on the date of receipt of such notice by the Agent or the Company, as the case may be, or such later date as may be required pursuant to Section 8(a) or (b). If such termination shall occur prior to the Settlement Date for any sale of Shares, such sale shall settle in accordance with the provisions of Section 2 hereof.

34

9. Indemnity and Contribution.

(a) Each SDC Party agrees, jointly and severally to indemnify, defend and hold harmless the Agent, its affiliates, directors and officers and each person, if any, who controls the Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Agent or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 12 being deemed to include any Basic Prospectus, the Prospectus Supplement, the Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company, which “issuer information” is filed or required to be filed with the Commission pursuant to Rule 433(d) under the Act, or any road show as defined in Rule 433(h) under the Act (a “road show”), or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except, with respect to such Prospectus or any Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning the Agent furnished in writing by or on behalf of the Agent through you to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading, and will reimburse each “indemnified party” (defined below) for any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending against any loss, damage, expense, liability, claim, action, litigation, investigation or proceeding whatsoever (whether or not such indemnified party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to the above as such fees and expenses are incurred.

(b) The Agent agrees to indemnify, defend and hold harmless each SDC Party, the directors of the Company, the, officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any SDC Party or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning the Agent furnished in

35

writing by or on behalf of the Agent through you to the Company expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning the Agent furnished in writing by or on behalf of the Agent through you to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against an SDC Party or the Agent (as applicable, the “indemnifying party”) pursuant to subsection ((a) or (b), respectively, of this Section 9, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the retention of counsel reasonably satisfactory to such indemnified party, and pay all legal or other fees and expenses related to such Proceeding or incurred in connection with such indemnified party’s enforcement of subsection (a) or (b), respectively, of this Section 9; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability that such indemnifying party may have to any indemnified party or otherwise. The indemnified party or parties shall have the right to retain its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the retention of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding, (ii) the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, retained counsel to defend such Proceeding or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them that are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the fees or expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 9(c), then the indemnifying party agrees that

36

it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) or (b) of this Section 9 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the SDC Parties on the one hand and the Agent on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the SDC Parties on the one hand and of the Agent on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the SDC Parties on the one hand and the Agent on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Shares pursuant to this Agreement and any Terms Agreements and the total discounts and commissions received by the Agent in connection therewith bear to the aggregate Gross Sales Price of such Shares. The relative fault of the SDC Parties on the one hand and of the Agent on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by an SDC Party or by the Agent and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e) Each SDC Party and the Agent agrees that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 9, the Agent shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by the Agent with respect to the offering of the Shares pursuant to this Agreement and any Terms Agreements exceeds the amount of any damages that the Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

37

(f) The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the SDC Parties contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Agent, its partners, agents, directors, officers or members or any person (including each partner, officer, director or member of such person) who controls the Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of each SDC Party, the directors of the Company, the, officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares to be sold by the Company pursuant to this Agreement and any Terms Agreements. Each SDC Party and the Agent agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of any SDC Party, against any of the Company’s officers or directors in connection with the issuance and sale of the Shares, or in connection with the Registration Statement, any Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus.

Ladies and Gentlemen:

We have acted as counsel to SmileDirectClub, Inc., a Delaware corporation (the “Company”), in connection with the Company’s issuance and sale, through UBS Securities LLC, as sales agent (the “Agent”), of shares of the Company’s Class A common stock, par value $0.0001 per share (“Common Stock”), having an aggregate offering price of up to $100.0 million (the “Shares”), from time to time and at various prices in an “at the market” offering pursuant to (i) that certain Distribution Agreement, dated November 7, 2022 (the “Distribution Agreement”), by and between the Company and the Agent, and (ii) the Company’s Registration Statement on Form S-3 (File No. 333-267370), filed with the Securities and Exchange Commission (the “Commission”) on September 9, 2022 (the “Registration Statement”) and which became effective on October 4, 2022, the base prospectus filed as part of the Registration Statement, dated October 4, 2022 (the “Base Prospectus”), and the final prospectus supplement dated November 7, 2022 (together with the Base Prospectus, the “Prospectus”).

In connection with our representation, we have examined: (i) the Distribution Agreement, (ii) the Registration Statement and the Prospectus, (iii) the Amended and Restated Certificate of Incorporation of the Company, (iv) the Amended and Restated Bylaws of the Company, and (v) the proceedings and actions taken by the Board of Directors of the Company to authorize and approve the transactions contemplated by the Distribution Agreement, the execution and delivery of the Distribution Agreement, and the sale and issuance of the Shares (the “Board Resolutions”). We have also considered such matters of law and of fact, including the examination of originals or copies, certified or otherwise identified to our satisfaction, of such records and documents of the Company, certificates of officers, directors and representatives of the Company, certificates of public officials, and such other documents as we have deemed appropriate as a basis for the opinions set forth below. In our examination of the above-referenced documents, we have assumed the genuineness of all signatures, the authenticity of all documents, records, certificates, and instruments submitted to us as originals and the conformity with the originals of all documents, records, certificates, and instruments submitted to us as copies. In addition, in expressing the opinion set forth below, we have assumed that the Company will issue the Shares in accordance with the Board Resolutions.

Based upon, subject to and limited by the foregoing, we are of the opinion that, upon the issuance of the Shares pursuant to the terms of the Distribution Agreement and the receipt by the Company of the consideration for the Shares pursuant to the terms of the Distribution Agreement, the Shares will be validly issued, fully paid, and nonassessable.

This opinion is issued as of the date hereof, and we assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof. This opinion is limited to the matters set forth herein, and no other opinion should be inferred beyond the matters expressly stated.

We consent to the filing of this opinion in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”), as Exhibit 5.1 to the Company’s Current Report on Form 8-K filed with the Commission on the date hereof, to the incorporation by reference of this opinion into the Registration Statement and the Prospectus and to the references to our firm therein. In giving our consent, we do not admit that we are “experts” within the meaning of Section 11 of the Securities Act or within the category of persons whose consent is required by Section 7 of the Securities Act.
