AMENDED AND RESTATED

CONFIDENTIAL MEMORANDUM OF UNDERSTANDING

(Adopted as of May 8, 2018)

(Amended and Restated as of June 15, 2018)

This amended and restated confidential memorandum of understanding (this “ MOU ”) is made and entered into between PeerStream, Inc. (f/k/a Snap Interactive, Inc.), a Delaware corporation (the “ Company ”), and Clifford Lerner, a director, officer, employee, and stockholder of the Company (“ Mr. Lerner ” or “ Employee ”).

WHEREAS , the Company has arranged for Mr. Lerner to sell 60,000 shares of the Company’s common stock to a third party investor pursuant to a stock purchase agreement, to be dated the date hereof, at a price of $5.00 per share (the “ Purchase Agreement ”); and

WHEREAS , in connection with Mr. Lerner’s entry into the Purchase Agreement, the parties desire to enter into this MOU.

NOW, THEREFORE, BE IT :

In consideration of the premises and the mutual promises herein made, and subject to and conditioned upon Mr. Lerner, the other seller, and the third party investor’s simultaneous entry into the Purchase Agreement, the Company and Mr. Lerner agree as follows:

1. Subject to the terms otherwise set forth herein, Mr. Lerner will resign as an officer and employee as soon as practicable after the date hereof and, simultaneously with such resignation, enter into a consulting agreement (the “ Consulting Agreement ”) on substantially the same terms as Mr. Lerner’s Employment Agreement, dated October 7, 2016, by and between the Company and Mr. Lerner (the “ Lerner Employment Agreement ”) that extends through October 2019 for a lump sum, up-front payment of $100,000, in which case his unvested restricted shares will continue to vest as scheduled, and the Company will, in order to assist Mr. Lerner in satisfying his tax withholding obligations with respect to such restricted shares that vest on the second anniversary of the closing date of the Company’s merger with AVM Software, Inc. (the “ Merger ”), withhold a number of restricted shares that would otherwise be acquired upon such vesting with a fair market value equal to the lesser of (a) Mr. Lerner’s tax withholding obligation with respect to the vesting shares and (b) $100,000, with the remaining amount of the tax withholding obligation, if any, payable by Mr. Lerner. For the avoidance of doubt, (i) nothing in this MOU shall obligate the Company to withhold any shares of restricted stock held by Mr. Lerner that vest upon the third anniversary date of the Merger or to assist Mr. Lerner with his tax obligations incurred in connection with the vesting of such restricted stock at that time, (ii) the Consulting Agreement will contain non-solicitation, non-disparagement, confidentiality, indemnification and termination for “cause” provisions (including, without limitation, the definition of “Cause” and the accelerated vesting obligations in connection with termination events) on substantially the same terms as the Lerner Employment Agreement and (iii) upon Mr. Lerner’s resignation, the Lerner Employment Agreement will be terminated and will have no further force nor effect, and the Company shall be under no obligation to make any further payments under the Lerner Employment Agreement. The parties hereby agree that the non-solicitation clause in the Consulting Agreement shall include carve-outs for Darrell Lerner and Lou Kerner, but shall not include carve-outs for any other individuals or entities.

2. In connection with Mr. Lerner’s resignation, the Company will simultaneously waive its right to enforce the non-competition provisions set forth in Section 4(b) and Section 7(a) of the Lerner Employment Agreement in total, and Mr. Lerner will no longer be subject to this or any other non-competition provisions.

3. Effective as of the date of this MOU, Mr. Lerner will not sell any shares of the Company’s common stock publicly until October 31, 2018 (such period, the “ Restricted Period ”). Notwithstanding the foregoing, Mr. Lerner is free to enter into a 10b5-1 plan during the Restricted Period, provided that (i) no sales of the Company’s common stock may be consummated under such 10b5-1 plan until after the expiration of the Restricted Period and (ii) any such 10b5-1 plan includes a provision that automatically terminates such plan following a notification to the broker under such plan that Mr. Lerner intends to publicly offer all or a portion of his shares of the Company’s common stock in a registered offering.

4. The Consulting Agreement will include language subjecting Mr. Lerner to trading and sales volume limitations in accordance with (i) Rule 144(e) under the Securities Act of 1933, as amended (the “ Securities Act ”), regardless of whether such Rule 144 is otherwise legally applicable, and (ii) the Company’s written insider trading policy in effect on the date hereof (the “ Insider Trading Policy ”); provided that (a) the Rule 144(e) restriction and Mr. Lerner’s obligations to comply with the Insider Trading Policy shall terminate 13 months following the date hereof, and (b) in no event shall Mr. Lerner, during the term of the Consulting Agreement, conduct any sales of the Company’s common stock at a price less than $4 per share.

5. In connection with Mr. Lerner’s resignation, the Company and Mr. Lerner will enter into an amendment to Mr. Lerner’s Registration Rights Agreement, dated October 7, 2016 (the “ Registration Rights Agreement ”), by and between Mr. Lerner and the Company, to provide that Mr. Lerner may only exercise his demand registration rights in connection with a firm commitment underwritten offering. All other rights under the agreement will remain in full.

6. The Company shall use commercially reasonable efforts to consummate, within 60 days of the date hereof, an underwritten public offering of shares of the Company’s common stock held by certain of the Company’s existing stockholders, which such transaction would include a minimum of 75,000 shares of the Company’s common stock held by Mr. Lerner (such transaction, the “ Block Trade ”). If (i) the Company and the other selling stockholders (other than Mr. Lerner) participating in the Block Trade have agreed on the economic terms of the transaction, (ii) the Company has entered into definitive documentation or filed a registration statement with respect to the Block Trade prior to October 31, 2018 and (iii) Mr. Lerner refuses to participate in the Block Trade, then the Restricted Period will automatically extend through January 31, 2019. In connection with the Block Trade, Mr. Lerner agrees to enter into a customary “lock-up” agreement in favor of the lead underwriter in the Block Trade that would extend for a period of three months following the consummation of the Block Trade.

7. The Company agrees that there is no conflict of interest that would prevent Haynes and Boone, LLP (“ Haynes and Boone ”) from providing routine legal advice and services to Mr. Lerner in connection with selling his shares of the Company’s common stock, including providing appropriate opinions and filings. In the event that (i) Mr. Lerner participates in the Block Trade, (ii) the Company fails to enter into definitive documentation for the Block Trade or file a registration with respect to the Block Trade by the end of the day on October 31, 2018 or (iii) Mr. Lerner refuses to participate in the Block Trade due to the underwriter(s) in the Block Trade requiring Mr. Lerner to enter into a “lock-up” agreement with a duration of more than three months, the Company will pay the legal fees and expenses of Haynes and Boone associated with (a) any filings required by Mr. Lerner under Section 16 of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), including any Forms 3, 4 or 5, (b) any beneficial ownership reports required under Section 13 of the Exchange Act, including any amendments to Mr. Lerner’s Schedule 13D, (c) any legal opinions or related documentation associated with removing restrictive legends on shares of Company common stock sold by Mr. Lerner and (d) any questions from Mr. Lerner concerning, or other legal matters related to, the sale of Mr. Lerner’s shares in the Block Trade. Any communications by Mr. Lerner concerning the matters listed in clauses (a) through (d) above shall be made in writing to an email distribution list to be designated by the Company and Mr. Lerner shall not contact Haynes and Boone directly with respect to such matters; provided, however, that Mr. Lerner may contact Haynes and Boone directly if the Company fails to respond to an inquiry from Mr. Lerner within two business days. Any responses by the Company to Mr. Lerner’s inquiries shall also copy representatives of Haynes and Boone and any correspondence between the Company and Haynes and Boone concerning the matters set forth in clauses (a) through (d) above shall copy Mr. Lerner. For the avoidance of doubt, the Company will not be responsible for any legal fees or expenses incurred by or on behalf of Mr. Lerner for any other matters, including, without limitation (a) advice related to the mechanics of, or compliance with, Rule 144 under the Securities Act, (b) advice related to the mechanics of, or compliance with, the Insider Trading Policy or any federal securities laws prohibiting insider trading, (c) advice related to the mechanics of Mr. Lerner’s Registration Rights Agreement or (d) advice related to the vesting of, and mechanics for the payment of taxes in connection with, Mr. Lerner’s shares of restricted stock; provided, however, that Mr. Lerner may refer any questions concerning such matters directly to the Company.
