Exhibit 10.23

9.4 Procedure. A Person intending to claim indemnification under this Article 9 (the “Indemnitee”) shall promptly provide written notice to the Party providing indemnification (the “Indemnitor”) of any Third Party Claim with respect to which the Indemnitee intends to claim such indemnification, which notice shall include a description of the Third Party Claim, the amount thereof (if known and quantifiable) and the basis for the Third Party Claim; provided that failure of the Indemnitee to give the Indemnitor notice as set forth herein shall not relieve the Indemnitor of its obligations hereunder, except to the extent that the Indemnitor is prejudiced thereby. The Indemnitor shall have the right, in its sole discretion and at its election by written notice to the Indemnitee within fifteen (15) days after delivering notice of the Third Party Claim to the Indemnitee, to conduct the defense against such Third Party Claim in its own name, provided that the Indemnitor (i) shall keep the Indemnitee reasonably informed regarding the status of such Third Party Claim, (ii) shall provide the Indemnitee the reasonable opportunity to consult with the Indemnitor regarding the defense of such claim, and (iii) may not settle or compromise any such Third Party Claim without the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld, conditioned or delayed) unless (A) such settlement or compromise involves no finding or admission of any breach by any Indemnitee of any obligation to any other Person or any violation by any Indemnitee of any Applicable Law, and (B) the sole relief provided in connection with such settlement or compromise is monetary damages that are paid in full by the Indemnitor. If the Indemnitee fails to timely give notice of such election to conduct the defense, it will be deemed to have elected not to conduct the defense of the subject Third Party Claim, and in such event the Indemnitor shall have the right, at its own cost and expense, to conduct the defense in good faith with counsel reasonably satisfactory to the Indemnitee; provided that the Indemnitor (x) shall keep the Indemnitee reasonably informed regarding the status of such Third Party Claim,
(y)shall provide the Indemnitee the reasonable opportunity to consult with the Indemnitor regarding the defense of such claim and (z) may not settle or compromise any such Third Party Claim without the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnitee, its employees and agents, shall cooperate fully with the Indemnitor and its legal representative(s) in the investigation and defense of any Third Party Claim covered by this Section 9.4.
9.5 Limitation of Damages.

(i)Insurance.

The Indemnitor shall remain liable for the balance of any Damages unpaid to the Indemnitee or the other Party.
(ii)Negligence, Illegal Act or Willful Misconduct. A Party shall not be liable to the extent that the other Party, its Affiliates or any of their respective officers, directors, employees, agents, successors and assigns caused, by the illegal conduct, gross negligence or willful misconduct, the Damages.

Notwithstanding anything to the contrary herein, (i) Seller shall not have any liability under Section 9.2 for any individual item (or series of related items) where the Damages relating thereto until the aggregate damages related thereto meet or exceed [****] United States dollars ($[****]) provided that once the Damages equal or exceed [****] United States dollars ($[****]), the Seller shall be liable for all Damages from the first dollar and (ii) Seller’s aggregate liability under Section 9.2(i) (other than for breaches of Fundamental Representations or Core Representations, or for claims related to fraud, gross negligence or willful misconduct) shall in no event exceed, on a cumulative basis, [****] percent ([****]%) of the Aggregate Consideration (as determined from time to time). Notwithstanding anything to the contrary herein, (a) Buyer shall not have any liability under Section 9.3 for any individual item (or series of related items) where the Damages relating thereto until the aggregate damages related thereto meet or exceed [****] United States dollars ($[****]) provided that once the Damages equal or exceed [****] United States dollars ($[****]), the Buyer shall be liable for all Damages from the first dollar and (b) Buyer’s aggregate liability under Section 9.3(i) (other than for breaches of Fundamental Representations or Core Representations, or for claims related to fraud, gross negligence or willful misconduct) shall in no event exceed, on a cumulative basis, [****] percent ([****]%) of the Aggregate Consideration (as determined from time to time).

This Agreement, including all the Exhibits, sets forth the entire understanding of the Parties with respect to the subject matter hereof and cancels and supersedes all previous communications, representations or understandings, and agreements, whether oral or written, between the Parties relating to the subject matter hereof including the Prior Confidentiality Agreement. Information disclosed under the Prior Confidentiality Agreement shall be deemed to be Confidential Information disclosed under this Agreement and subject to the same obligations of confidentiality and use as other Confidential Information disclosed hereunder.
11.2 Amendment. No modification or amendment of any provision of this Agreement shall be valid or effective unless made in writing and signed by duly authorized officers of each Party.
11.3 Assignment. Neither Party may assign, transfer, charge or otherwise encumber this Agreement or any right, benefit or interest under it, nor transfer it without the prior written consent of the other Party provided that a Party may assign this Agreement to any Affiliate or to any successor in interest by way of merger, acquisition or sale of all or substantially all of its assets to which this Agreement relates, provided that such successor agrees in writing to be bound by the terms of this Agreement as if it were the assigning Party. Each Party agrees that, notwithstanding any provisions of this Agreement to the contrary, if this Agreement is assigned by a Party in connection with a merger, acquisition or sale of all or substantially all of its assets, such assignment shall not provide the non-assigning Party with rights or access to any intellectual property or technology of the acquirer of the assigning Party beyond that which is specifically contemplated in this Agreement.

11.6 Waiver. A waiver of any default, breach or non-compliance under this Agreement is not effective unless signed by the Party granting such waiver. No waiver will be inferred from or implied by any failure to act or delay in acting by a Party in respect of any default, breach, non-observance or by anything done or omitted to be done by the other Party.

Warrant to Purchase
Shares of
Common Stock
As Herein Described
May __, 2018
WARRANT TO PURCHASE COMMON STOCK OF
PROVENTION BIO, INC.
This is to certify that, for value received, MacroGenics, Inc., or a proper assignee (the “Holder”), is entitled to purchase up to 2,162,389 shares (“Warrant Shares”) of common stock, $0.0001 par value per share (the “Common Stock”), of Provention Bio, Inc., a Delaware corporation (the “Company”), subject to the provisions of this Warrant. This Warrant shall be exercisable at Two Dollars and Fifty Cents ($2.50) per share (the “Exercise Price”). This Warrant also is subject to the following terms and conditions:
1.Exercise and Payment; Exchange.
(a)This Warrant may be exercised in whole or in part at any time from and after the date hereof (the “Commencement Date”) through the close of business on May __, 2025 (the “Expiration Date”), at which time this Warrant shall expire and become void, but if such date is a day on which federal or state chartered banking institutions located in the State of New York are authorized to close, then on the next succeeding day which shall not be such a day. Exercise (“Exercise”) shall be by presentation and surrender to the Company, or at the office of any transfer agent designated by the Company (the “Transfer Agent”), of (i) this Warrant, (ii) the attached exercise form properly executed, and (iii) a certified or official bank check for the Exercise Price for the number of Warrant Shares specified in the exercise form. If this Warrant is exercised in part only, the Company or the Transfer Agent shall, upon surrender of the Warrant, execute and deliver a new Warrant evidencing the rights of the Holder to purchase the remaining number of Warrant Shares purchasable hereunder. Upon receipt by the Company of this Warrant, the properly executed exercise form, and payment as aforesaid, the Holder shall be deemed to be the holder of record of the Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such Warrant Shares shall not then be actually delivered to the Holder. Under no circumstance shall the Company be required to make any cash payments or net cash settlement to the Holder in lieu of delivery of the Warrant Shares.

Exhibit 10.23
(b)In lieu of exercising this Warrant for cash pursuant to Section 2(a), if the fair market value of one Warrant Share is greater than the Exercise Price (at the date of calculation as set forth below), the Holder may elect to receive a number of Warrant Shares equal to the value of this Warrant (or of any portion of this Warrant being canceled) by Exercise of this Warrant, in which event the Company shall issue to the Holder that number of Warrant Shares computed using the following formula:

X | = | Y (A – B)
|  | A

Where:
X = The number of Warrant Shares to be issued to the Holder
Y = The number of Shares purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such calculation)
A = The fair market value of one Warrant Share (at the date of such calculation)
B = The Exercise Price (as adjusted to the date of such calculation)
For purposes of the calculation above, the fair market value of one Warrant Share shall be determined as set forth in Section 3(a) – (c) below.
(b)Conditions to Exercise or Exchange. The restrictions in Section 7 shall apply, to the extent applicable by their terms, to any exercise or exchange of this Warrant permitted by this Section 1.
2.Reservation of Shares. The Company shall, at all times until the expiration of this Warrant, reserve for issuance and delivery upon exercise of this Warrant the number of Warrant Shares which shall be required for issuance and delivery upon exercise of this Warrant. Upon issuance, all Warrant Shares will be validly issued and outstanding, fully paid and non-assessable, and free from all taxes, liens and charges with respect to the issuance thereof.

Exhibit 10.23
3.Fractional Interests. The Company shall not issue any fractional shares or scrip representing fractional shares upon the exercise or exchange of this Warrant. With respect to any fraction of a share resulting from the exercise or exchange hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the current fair market value per share of Common Stock, determined as follows:
(a)If the Common Stock is listed on a national securities exchange or admitted to unlisted trading privileges on such an exchange, the current fair market value shall be the last reported sale price of the Common Stock on such exchange on the last business day prior to the date of exercise of this Warrant or if no such sale is made on such day, the mean of the closing bid and asked prices for such day on such exchange;
(b)If the Common Stock is not so listed or admitted to unlisted trading privileges on a national securities exchange, the current fair market value shall be the mean of the last bid and asked prices reported on the last business day prior to the date of the exercise of this Warrant by the OTC Markets Group, Inc.; or
(c)If the Common Stock is not so listed or admitted to unlisted trading privileges on a national securities exchange and bid and asked prices are not so reported, the current fair market value shall be an amount, not less than book value, determined in such reasonable manner as may be prescribed by the Company in good faith.
4.No Rights as Shareholder. This Warrant shall not entitle the Holder to any rights as a shareholder of the Company, either at law or in equity. The rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein.
5.Adjustments in Number and Exercise Price of Warrant Shares.
5.1 The number of shares of Common Stock for which this Warrant may be exercised and the Exercise Price therefor shall be subject to adjustment as follows:
(a)If the Company is recapitalized through the subdivision or combination of its outstanding shares of Common Stock into a larger or smaller number of shares, the number of Warrant Shares shall be increased or reduced, as of the record date for such recapitalization, in the same proportion as the increase or decrease in the outstanding shares of Common Stock, and the Exercise Price shall be adjusted so that the aggregate amount payable for the purchase of all of the Warrant Shares issuable hereunder immediately after the record date for such recapitalization shall equal the aggregate amount so payable immediately before such record date.
(b)If the Company declares a dividend on Common Stock payable in Common Stock or securities convertible into Common Stock, the number of shares of Common Stock for which this Warrant may be exercised shall be increased as of the record date for determining which holders of Common Stock shall be entitled to receive such dividend, in proportion to the increase in the number of outstanding shares (and shares of Common Stock issuable upon conversion of all such securities convertible into Common Stock) of Common Stock as a result of such dividend, and the Exercise Price shall be adjusted so that the aggregate amount payable for the purchase of all the Warrant Shares issuable hereunder immediately after the record date for such dividend shall equal the aggregate amount so payable immediately before such record date.

Exhibit 10.23
(c)If the Company distributes to holders of its Common Stock, other than as part of its dissolution or liquidation or the winding up of its affairs, any evidence of indebtedness or any of its assets (other than cash, Common Stock or securities convertible into Common Stock), the Company shall give written notice to the Holder of any such distribution at least fifteen (15) days prior to the proposed record date in order to permit the Holder to exercise this Warrant on or before the record date. There shall be no adjustment in the number of shares of Common Stock for which this Warrant may be exercised, or in the Exercise Price, by virtue of any such distribution.
(d)If the Company offers rights or warrants to the holders of Common Stock which entitle them to subscribe to or purchase additional Common Stock or securities convertible into Common Stock, the Company shall give written notice of any such proposed offering to the Holder at least fifteen (15) days prior to the proposed record date in order to permit the Holder to exercise this Warrant on or before such record date. There shall be no adjustment in the number of shares of Common Stock for which this Warrant may be exercised, or in the Exercise Price, by virtue of any such distribution.
(e)If the event, as a result of which an adjustment is made under paragraph (a) or (b) above, does not occur, then any adjustments in the Exercise Price or number of shares issuable that were made in accordance with such paragraph (a) or (b) shall be adjusted to the Exercise Price and number of shares as were in effect immediately prior to the record date for such event.
5.2 In the event of any reorganization or reclassification of the outstanding shares of Common Stock (other than a change in par value or from no par value to par value, or from par value to no par value, or as a result of a subdivision or combination) or in the event of any consolidation or merger of the Company with another entity after which the Company is not the surviving entity, at any time prior to the expiration of this Warrant, upon subsequent exercise of this Warrant the Holder shall have the right to receive the same kind and number of shares of common stock and other securities, cash or other property as would have been distributed to the Holder upon such reorganization, reclassification, consolidation or merger had the Holder exercised this Warrant immediately prior to such reorganization, reclassification, consolidation or merger, appropriately adjusted for any subsequent event described in this Section 5. The Holder shall pay upon such exercise the Exercise Price that otherwise would have been payable pursuant to the terms of this Warrant. If any such reorganization, reclassification, consolidation or merger results in a cash distribution in excess of the then applicable Exercise Price, the Holder may, at the Holder’s option, exercise this Warrant without making payment of the Exercise Price, and in such case the Company shall, upon distribution to the Holder, consider the Exercise Price to have been paid in full, and in making settlement to the Holder, shall deduct an amount equal to the Exercise Price from the amount payable to the Holder.

Exhibit 10.23
5.3 If the Company shall, at any time before the expiration of this Warrant, dissolve, liquidate or wind up its affairs, the Holder shall have the right to receive upon exercise of this Warrant, in lieu of the shares of Common Stock of the Company that the Holder otherwise would have been entitled to receive, the same kind and amount of assets as would have been issued, distributed or paid to the Holder upon any such dissolution, liquidation or winding up with respect to such Common Stock receivable upon exercise of this Warrant on the date for determining those entitled to receive any such distribution. If any such dissolution, liquidation or winding up results in any cash distribution in excess of the Exercise Price provided by this Warrant, the Holder may, at the Holder’s option, exercise this Warrant without making payment of the Exercise Price and, in such case, the Company shall, upon distribution to the Holder, consider the Exercise Price to have been paid in full and, in making settlement to the Holder, shall deduct an amount equal to the Exercise Price from the amount payable to the Holder.
6.Notices to Holder. So long as this Warrant shall be outstanding (a) if the Company shall pay any dividends or make any distribution upon the Common Stock otherwise than in cash or (b) if the Company shall offer generally to the holders of Common Stock the right to subscribe to or purchase any shares of any class of Common Stock or securities convertible into Common Stock or any similar rights or (c) if there shall be any capital reorganization of the Company in which the Company is not the surviving entity, recapitalization of the capital stock of the Company, consolidation or merger of the Company with or into another corporation, sale, lease or other transfer of all or substantially all of the property and assets of the Company, or voluntary or involuntary dissolution, liquidation or winding up of the Company, then in such event, the Company shall cause to be mailed to the Holder, at least thirty (30) days prior to the relevant date described below (or such shorter period as is reasonably possible if thirty (30) days is not reasonably possible), a notice containing a description of the proposed action and stating the date or expected date on which a record of the Company’s shareholders is to be taken for the purpose of any such dividend, distribution of rights, or such reclassification, reorganization, consolidation, merger, conveyance, lease or transfer, dissolution, liquidation or winding up is to take place and the date or expected date, if any is to be fixed, as of which the holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such event.
7.Transfer, Exercise, Exchange, Assignment or Loss of Warrant, Warrant Shares or Other Securities.
7.1 This Warrant may be transferred, exercised, exchanged or assigned (“transferred”), in whole or in part, subject to the following restrictions. This Warrant and the Warrant Shares or any other securities (“Other Securities”) received upon exercise of this Warrant shall be subject to restrictions on transferability until registered under the Securities Act of 1933, as amended (the “Securities Act”), unless an exemption from registration is available. Until this Warrant and the Warrant Shares or Other Securities are so registered or exempt from registration, this Warrant and any certificate for Warrant Shares or Other Securities issued or issuable upon exercise of this Warrant shall contain a legend on the face thereof, in form and substance satisfactory to counsel for the Company, stating that this Warrant, the Warrant Shares or Other Securities may not be sold, transferred or otherwise disposed of unless, in the opinion of counsel satisfactory to the Company, which may be counsel to the Company, that this Warrant, the Warrant Shares or Other Securities may be transferred without such registration. This Warrant and the Warrant Shares or Other Securities may also be subject to restrictions on transferability under applicable state securities or blue sky laws.

Exhibit 10.23
7.2 Any transfer permitted hereunder shall be made by surrender of this Warrant to the Company or to the Transfer Agent at its offices with a duly executed request to transfer the Warrant, which shall provide adequate information to effect such transfer and shall be accompanied by funds sufficient to pay any transfer taxes applicable. The Company or Transfer Agent shall, without charge, execute and deliver a new Warrant in the name of the transferee named in such transfer request, and this Warrant promptly shall be cancelled.
7.3 Upon receipt by the Company of evidence satisfactory to it of loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, of reasonable satisfactory indemnification, or, in the case of mutilation, upon surrender of this Warrant, the Company will execute and deliver, or instruct the Transfer Agent to execute and deliver, a new Warrant of like tenor and date, any such lost, stolen or destroyed Warrant thereupon shall become void.

Re: Provention Bio, Inc. - Lock-Up Agreement
Ladies and Gentlemen:
This Lock-Up Agreement is being delivered to you in connection with the Warrants (the “Warrants”), each dated as of May __, 2018 between Provention Bio, Inc., a Delaware Corporation, (the “Company”) and MacroGenics, Inc., a Delaware corporation (the “Subscriber”), in which Subscriber desires to acquire warrants exercisable into an aggregate of 2,432,688 shares of Common Stock, par value $0.0001 per share (the “Common Stock”), of the Company in consideration of the Company’s and Subscriber’s entry into an Asset Purchase Agreement and License Agreement, each dated as of May __, 2018.
In order to induce MDB Capital Group, LLC (“MDB”) to locate investors to participate in an initial public offering by the Company, the undersigned agrees that, commencing on the earlier of (a) the date of the final prospectus relating to the Company’s initial public offering of its Common Stock (the “IPO”) and (b) the listing of the Company’s Common Stock on an exchange or any tier of The NASDAQ Stock Market or New York Stock Exchange and ending on the date that is 12 months thereafter (the “Lock-Up Period”), the undersigned will not, and will cause all affiliates (as defined in Rule 144 promulgated under the Securities Act of 1933 Act, as amended) of the undersigned not to, (i) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, or securities exercisable or convertible into shares of Common Stock, held as of the date hereof (the “Subscriber’s Shares”) or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Subscriber’s Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise.
The foregoing restriction is expressly agreed to preclude the undersigned, and any affiliate of the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Subscriber’s Shares even if the Subscriber’s Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any of the Subscriber’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from the Subscriber’s Shares.

Exhibit 10.23
Notwithstanding the foregoing, the undersigned may transfer the Subscriber’s Shares, provided that in case of items (i) through (v) below, any such transfer shall not involve a disposition for value, and provided further that any transferee shall agree to be bound by the terms of this Lock-up Agreement:
(i)bona fide gift or gifts or by will or intestate succession upon the death of the undersigned; or
(ii)to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned; or
(iii)if the undersigned is a trust, any distribution to a beneficiary of the trust or to the estate of a beneficiary of such trust and such transfer is not for value; or
(iv)as a distribution or transfer to stockholders, members, limited partners, or other securityholders of the undersigned or to regular employees of the undersigned whether or not for value; or
(v)to any corporation, partnership, limited liability company or other entity all of the beneficial ownership interests of which are held by the undersigned or to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by or under common control with the undersigned.
For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.
Notwithstanding anything contrary in this Lock-Up Agreement, (i) the undersigned may exercise warrants to purchase shares of Common Stock, provided that the underlying shares of Common Stock shall continue to be subject to the restrictions on transfer set forth in this letter agreement, (ii) the undersigned can enter into a sales plan pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), provided that no sales, dispositions or other transfers of the Subscriber’s Shares may be made under such plan during the Lock-Up Period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required of or voluntarily made by or on behalf of the undersigned or the Company;
(iii)nothing in this Lock-Up Agreement shall prevent the transfer of securities of the Company pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of Common Stock, provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Subscriber’s Shares shall remain subject to the restrictions contained in this Lock-Up Agreement, and (iv) nothing in this Lock-Up Agreement shall prevent the transfer of the Subscriber’s Shares with the written consent of MDB and the agreement of the transferee that it will be subject to the restrictions contained herein.
In order to enforce this covenant, the Company shall impose stop-transfer instructions preventing the Company’s transfer agent (the “Transfer Agent”) from effecting any actions in violation of this Lock-Up Agreement. The undersigned agrees and consents to the entry of stop transfer instructions with the Company’s Transfer Agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions. The Company is a third party beneficiary of this provision.

Exhibit 10.23
The undersigned acknowledges that the execution, delivery and performance of this Lock-Up Agreement is a material inducement to MDB and the Company to complete the transactions contemplated by the Subscription Agreement and the Private Placement, and that MDB and the Company shall each be entitled to specific performance of the undersigned’s obligations hereunder. The undersigned hereby represents that the undersigned has the power and authority to execute, deliver and perform this Lock-Up Agreement, that the undersigned has received adequate consideration therefor and that the undersigned will indirectly benefit from the closing of the transactions contemplated by the Subscription Agreement entered into in connection with the Private Placement.
The undersigned understands and agrees that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.
At the discretion of MDB some or all of the Subscriber’s Shares may be released from the restrictions of this Lock-Up Agreement, and the Company will take the required action to permit the securities so released to be free of the restrictions of this Lock-Up Agreement.
This Lock-Up Agreement may be executed in two counterparts, each of which shall be deemed an original but both of which shall be considered one and the same instrument.
This Lock-Up Agreement will be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflicting provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the laws of any jurisdiction other than the State of Delaware to be applied. In furtherance of the foregoing, the internal laws of the State of Delaware will control the interpretation and construction of this Lock-Up Agreement, even if under such jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.
