The Company has obtained director’s and officer’s insurance in such amounts as is customary for a similarly situated company engaging in an initial public offering.

(ss) Neither the Company and its Subsidiaries, nor any director, officer, agent or employee of either the Company or any Subsidiary has directly or indirectly, (1) made any unlawful contribution to any federal, state, local and foreign candidate for public office, or failed to disclose fully any contribution in violation of law, (2) made any payment to any federal, state, local and foreign governmental officer or official, or other person charged with similar public or quasi-public duties, other than payments required or permitted by the laws of the United States or any jurisdiction thereof, (3) violated or is in violation of any provisions of the U.S. Foreign Corrupt Practices Act of 1977, or (4) made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment.

(i) The Company shall indemnify and hold harmless each Underwriter, its directors, officers, employees and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), from and against any and all losses, claims, liabilities, expenses and damages, joint or several, (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted (whether or not such Indemnified Party is a party thereto)), to which it, or any of them, may become subject under the Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (a) any untrue statement or alleged untrue statement made by the Company in Section 3 of this Agreement, (b) any untrue statement or alleged untrue statement of any material fact contained in (1) any Preliminary Prospectus, the Registration Statement or the Final Prospectus or any amendment or supplement thereto, (2) any Issuer Free Writing Prospectus or any amendment or supplement thereto, (3) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) by any Underwriter, (4) any Written Testing-the-Waters Communication or (5) any application or other document, or any amendment or supplement thereto, executed by the Company based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Shares under the securities or Blue Sky laws thereof or filed with the Commission or any securities association or securities exchange (each, an “Application”), or (c) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Final Prospectus, Issuer Free Writing Prospectus, or Written Testing-the-Waters Communication, or any amendment or supplement thereto, or in any Permitted Issuer Information or any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person and is based solely on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with written information furnished to the Company by any Indemnified Party through the Representative expressly for inclusion in the Registration Statement, any Preliminary Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, or Written Testing-the-Waters Communication, or in any amendment or supplement thereto or in any Permitted Issuer Information or any Application, it being understood and agreed that the only such information furnished by any Indemnified Party consists of the information described as such in subsection (ii) below. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(ii) Each Underwriter will severally and not jointly indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Final Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus or the Final Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any Written Testing-the-Waters Communication, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. The Company acknowledges that, for all purposes under this Agreement, the statements set forth in the [seventh, ninth and tenth paragraphs] under the caption “Underwriting” in any Preliminary Prospectus and the Final Prospectus constitute the only information relating to the Underwriters furnished in writing to the Company by the Underwriters expressly for inclusion in the Registration Statement, any Preliminary Prospectus or the Final Prospectus.

(iii) Promptly after receipt by an indemnified party under subsection (i) or (ii) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (a) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (b) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(iv) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (i) or (ii) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (iii) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and bear to the Fee received by the Underwriters, as set forth in the table on the cover page of the Final Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (iv) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (iv). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (iv) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (iv), no Underwriter shall be required to contribute any amount in excess of Fee applicable to the Shares. 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. The Underwriters’ obligations in this subsection (iv) to contribute are several in proportion to their respective obligations and not joint.

9. Termination.

(i) The obligations of the Underwriters under this Agreement may be terminated at any time prior to the Closing Date, by notice to the Company from the Representative, without liability on the part of the Underwriters to the Company if, prior to delivery and payment for the Shares, in the sole judgment of the

Representative: (a) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the opinion of the Representative, will in the future materially disrupt, the securities markets or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States is such as to make it, in the judgment of the Representative, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (b) there has occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the judgment of the Representative, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (c) trading in the Shares or any securities of the Company has been suspended or materially limited by the Commission; (d) trading generally on the New York Stock Exchange, Inc., NYSE Amex or Nasdaq has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, FINRA, or any other governmental or regulatory authority; (e) a banking moratorium has been declared by any state or Federal authority; or (f) in the judgment of the Representative, there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the assets, properties, condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its Subsidiaries considered as a whole, whether or not arising in the ordinary course of business.

(ii) The obligations of the parties under this Agreement shall be automatically terminated in the event that notice is given to the Escrow Agent as determined prior to the close of business on the date scheduled for receipt of the Requisite Funds, that the Requisite Funds have not been deposited by the Investors into the Escrow Account by the close of business the Closing Date.

Re:

XBiotech, Inc. (the “Company”)—Restriction on Stock Sales

Dear Sir or Madam:

This letter is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by the Company, as issuer, and X.X. Xxxxxxxxx + Co., LLC, the representative (the “Representative”) of certain underwriters (the “Underwriters”) to be named therein. Upon the terms and subject to the conditions of the Underwriting Agreement, the Underwriters intend to effect a public offering of Common Stock of the Company (the “Shares”), as described in and contemplated by the registration statement of the Company on Form S-1, File No. 333-201813 (the “Registration Statement”), as filed with the Securities and Exchange Commission on February 2, 2015 (the “Offering”).

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director, or an owner of stock, options, warrants or other securities of the Company (the “Company Securities”), that the Company complete the proposed Offering.

The undersigned further recognizes that the Company Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Company Securities of the undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the placement effort.

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not (i) offer, sell, contract to sell, pledge, grant any option to purchase or otherwise dispose of (collectively, a “Disposition”) any Company Securities, or any securities convertible into or exercisable or exchangeable for, or any rights to purchase or otherwise acquire, any Company Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Shares”), pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a period commencing on the date hereof and ending 180 days after the date of the Company’s Prospectus first filed pursuant to Rule 424(b) under the Act, inclusive (the “Lock-Up Period”), without the prior written consent of the Representative or (ii) exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company to register under the Act the undersigned’s sale, transfer or other disposition of any of the Lock-Up Shares or other securities of the Company held by the undersigned, or to otherwise participate as a selling security holder in any manner in any

A-1

registration effected by the Company under the Act, including under the Registration Statement, during the Lock-Up Period. The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or reasonably expected to lead to or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Shares or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Lock-Up Shares.

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period, you have agreed that the foregoing restrictions shall not apply to:

(1)

the Shares being offered in the prospectus included in the Registration Statement;

(2)

any grant or exercise by the undersigned of any option or warrant to acquire any shares of Common Stock or options to purchase shares of Common Stock, pursuant to any stock option, stock bonus or other stock plan or arrangement;

(3)

any exchange of warrants to acquire preferred stock in exchange for warrants to acquire common stock made prior to the date of the Underwriting Agreement;

(4)

any transfer of Lock-Up Shares to any family member of the undersigned or to any trust for the direct or indirect benefit of the undersigned or any family member;

(5)

any bona fide gift;

(6)

any transfer of Lock-Up Shares by will or intestate succession;

(7)

any transfer of Lock-Up Shares solely to cover applicable withholding taxes due upon the vesting of stock-based awards under the Company’s 2005 Incentive Stock Option Plan;

(8)

any distribution or other transfer by a partnership to its partners or former partners or by a limited liability company to its members or retired members or by a corporation to its stockholders or former stockholders or to any wholly-owned subsidiary of such corporation;

(9)

any transfer to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned;

(10)

any transfer pursuant to a qualified domestic relations order or in connection with a divorce settlement;

(12)

any Company Securities acquired in open market transactions after completion of the offering contemplated by this agreement; provided that, no filing by any party under the Exchange Act or other public announcement shall be required or shall be voluntarily made in connection with such transfer;

provided that in the case of any transfer, gift or other disposition pursuant to (4), (5), (8), (9) or (10), the transferee, trust, donee or other recipient agrees to be bound in writing by the terms of this letter agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer (other than required filings under Section 16(a) and Section 13(d) or 13(g) of the Exchange Act and any filings made after the expiration of the Lock-Up Period).

Furthermore, no provision in this letter shall be deemed to restrict or prohibit (1) the transfer of Lock-Up Shares upon the completion of a bona fide third-party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s securities involving a change of control of the Company provided that (i) the per-share consideration for the Company Securities transferred as described above shall be greater than the public offering price per share in the Offering, (ii) all Company Securities subject to this letter agreement that are not so transferred, sold, tendered or otherwise disposed of remain subject to this letter agreement and (iii) it shall be a condition of transfer, sale, tender or other disposition that if such tender offer or other transaction is not completed, any Company Securities subject to this letter agreement shall remain subject to the restrictions herein and (2) the conversion of the outstanding preferred shares of the Company into shares of Common Stock, provided that any shares received upon such conversion shall be subject to restrictions on transfer set forth in this letter.

A-2

Notwithstanding anything herein to the contrary, nothing herein shall prevent the undersigned from establishing a 10b5-1 trading plan that complies with Rule 10b5-1 under the Exchange Act (“10b5-1 trading plan”) or from amending an existing 10b5-1 trading plan so long as there are no sales of Lock-Up Shares under such plans during the Lock-Up Period; and provided that, the establishment of a 10b5-1 trading plan or the amendment of a 10b5-1 trading plan shall only be permitted if (i) the establishment or amendment of such plan is not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding the establishment or amendment of such plan.

It is understood that, this lock-up agreement shall automatically terminate, and the undersigned shall be released from its obligations hereunder, upon the earliest to occur, if any, of (i) prior to the execution of the Underwriting Agreement, the Company advises the Representative in writing that it has determined not to proceed with the Offering, (ii) the Company files an application to withdraw the registration statement related to the Offering, (iii) the Underwriting Agreement (other than the provisions thereof that survive termination) is executed but is terminated prior to payment for and delivery of the Shares, or (iv) [ ], 2015, in the event that the Underwriting Agreement has not been executed by such date.
