The Company is in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

Title to Assets. The Company has good and marketable title to all tangible personal property owned by it that is material to its business, in each case free and clear of all liens except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company.

The Shares shall not be sold or transferred unless the transfer (i) complies with Rule 144, or an exemption from registration under the Securities Act or (ii) is pursuant to a registration statement under the Securities Act covering the resale of such Shares. Legend. Each certificate representing the Shares shall bear a legend substantially in the following form: “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR


 
ANY STATE SECURITIES LAW AND THEY MAY NOT BE OFFERED, SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE ASSIGNED BY ANY PERSON, INCLUDING A PLEDGEE, UNLESS (1) EITHER (a) SUCH SHARES FIRST SHALL HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (b) THE TRANSFER COMPLIES WITH RULE 144 OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND, IF REQUESTED BY THE COMPANY, THE COMPANY SHALL HAVE RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACTS IS THEN AVAILABLE, AND (2) THERE SHALL HAVE BEEN COMPLIANCE WITH ALL APPLICABLE STATE SECURITIES LAWS.” Legend Removal. The Shares shall not be required to bear the legend set forth in Section 3.2 (i) after the sale of such Shares pursuant to an effective registration statement under the Securities Act covering the resale of such Shares, (ii) following any sale of such Shares pursuant to Rule 144 or (iii) if such Shares are eligible for sale under Rule 144 without the need to satisfy the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions. Pieris agrees that following such time as the legend is no longer required under this Section 3.3, no later than two (2) Business Days following the delivery by Seagen of (i) an instrument, whether certificated or uncertificated, representing the Shares issued with a restrictive legend, (ii) a written request addressed to Pieris that such restrictive legend be removed, and (iii) customary broker and representation letters in form and substance reasonably satisfactory to Pieris, Pieris will deliver or cause to be delivered to Seagen an instrument, certificated or uncertificated as directed by Seagen, representing such Shares that is free from such restrictive legend; provided, however, that each party will be responsible for any fees it incurs in connection with such request and removal. Rule 144 Reporting. With a view to making available to Seagen the benefits of certain rules and regulations of the Commission which may permit the sale of the Shares to the public without registration, the Company agrees to use its commercially reasonable efforts to make and keep current public information with respect to the Company available, as those terms are understood and defined in Rule 144, at all times during the period commencing on the Execution Date and ending on the one-year anniversary of the Closing. 4. DEMAND REGISTRATION RIGHTS. Demand Registrations. At any time beginning on the date that is sixty (60) days after the date of Closing, Seagen will have the right to request registration of any of its Registrable Securities (which may, at Seagen’s request, be shelf registrations pursuant to Rule 415 promulgated under the Securities Act), which request or requests will specify the number of Registrable Securities intended to be transferred and the intended method of distribution of such Registrable Securities. Upon receipt of such request, and subject to Seagen’s compliance with Section 4.3 hereof, Pieris will use its commercially reasonable efforts to promptly, but in no event later than sixty (60) days following receipt of such request (or ninety (90) days following the receipt of such request if Pieris is not then eligible to register for resale the Registrable Securities on Form S-3), effect the registration under the Securities Act of the Registrable Securities so requested to be registered; provided, however, that Pieris will not be required to prepare and file (x) more than two registration statements hereunder nor (y) more than one registration statement within any twelve-month period, in each case, at the request of Seagen pursuant to this Section 4.1. Notwithstanding the foregoing, Pieris may delay the filing or effectiveness of any registration of Registrable Securities pursuant to this Section 4.1 or suspend the use of any registration statement (and Seagen hereby agrees not to offer or sell any Registrable Securities pursuant to such registration statement) for a period of not more than ninety (90) days if (i) Pieris reasonably believes that there is or may be in existence material


 
nonpublic information or events involving Pieris, the failure of which to be disclosed in the prospectus included in the registration statement could result in a Violation, (ii) all reports required to be filed by Pieris pursuant to the Exchange Act have not been filed by the required date (without regard to any extension), (iii) if Pieris furnishes Seagen a certificate signed by the principal executive officer of Pieris stating that in the good faith judgment of the Board, the filing or use of any registration statement covering Registrable Securities would be seriously detrimental to Pieris or its stockholders at such time and that the Board concludes, as a result, that it is in the best interests of Seagen and its stockholders to delay the filing or effectiveness of any registration of Registrable Securities pursuant to this Section 4.1 or suspend the use of any registration statement at such time, or (iv) if Pieris intends to file such Registration Statement concurrently with its next required Form 10-Q or Form 10-K, provided, however, that Pieris may not delay the filing or effectiveness of any registration of Registrable Securities or suspend the use of any registration statement pursuant to this clause (iii) for a period of more than one hundred twenty (120) calendar days, or (iv) the consummation of any business combination by Pieris has occurred or is probable for purposes of Rule 3-05 or Article 11 of Regulation S-X promulgated by the Commission or any similar successor rule. If Pieris exercises its right to delay the filing or effectiveness or suspend the use of a registration statement hereunder, the applicable time period during which the registration statement is to remain effective will be extended by a period of time equal to the duration of the suspension period. If so directed by Pieris, Seagen will (i) not offer to sell any Registrable Securities pursuant to the registration statement during the period in which the delay or suspension is in effect after receiving notice of such delay or suspension; and (ii) use its commercially reasonable efforts to deliver to Pieris (at Pieris’s expense) all copies, other than permanent file copies then in Seagen’s possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. Pieris will use its commercially reasonable efforts to maintain the continuous effectiveness of the registration statement for up to ninety (90) calendar days following the effective date of such registration statement or, if earlier, until the date on which (i) all of the Registrable Securities included in such registration statement have actually been sold or (ii) Seagen, together with its Affiliates, no longer beneficially owns more than 20% of the Shares. Registration Expenses. Pieris will pay all Registration Expenses incurred in connection with each registration of Registrable Securities pursuant to this Section 4. All Selling Expenses relating to the distribution of the Registrable Securities applicable to Registrable Securities sold by Seagen incurred in connection with each registration pursuant to this Section 4 will be borne by Seagen. Certain Conditions. It will be a condition of Seagen’s rights hereunder to have Registrable Securities owned by it registered that: (i) Seagen will reasonably cooperate with Pieris by supplying information and executing documents relating to Pieris or the securities of Pieris owned by Seagen in connection with such registration; and (ii) Seagen will enter into such undertakings and take such other actions relating to the conduct of the proposed offering that Pieris may request as being necessary to ensure compliance with federal and state securities laws and the securities laws of any applicable jurisdiction and the rules or other requirements of the applicable exchange. In the event of any registration under the Securities Act of any Registrable Securities pursuant to this Section 4, Pieris will indemnify and hold harmless Seagen, each of its directors, its officers, and its equity holders against such losses, claims, damages or liabilities (including reimbursement for reasonable and documented legal and other expenses) to which Seagen or any such director, officer or equity holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities arise out of or are based upon a Violation; provided, however, that the indemnity agreement contained in this Section 4.3 will not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without Pieris’s consent, which consent will not be unreasonably withheld, nor will Pieris be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with


 
written information furnished expressly for use in connection with such registration by any of such indemnified parties; and provided, further that Seagen will indemnify and hold harmless Pieris, each of its directors, its officers, and each person, if any, who controls Pieris within the meaning of the Securities Act, and any underwriter, and any other third party, as applicable, selling securities under such registration statement, against such losses, claims, damages or liabilities (including reimbursement for reasonable and documented legal and other expenses) to which Pieris or any such director, officer, controlling person, underwriter or other third party who may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities arise out of or are based upon a Seagen Violation, in each case, to the extent (and only to the extent) that such Seagen Violation occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any of such indemnifying parties, provided, however, that the indemnity agreement contained in this Section 4.3 will not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without Seagen’s consent, which consent will not be unreasonably withheld; provided, further, that in no event shall the obligations of Seagen in this Section 4.3 exceed the net proceeds received by it from the sale of its Registrable Securities related to the matter in which losses or damages are sought. Assignment of Registration Rights. Seagen’s right to request registration of its Registrable Securities as set forth in Section 4.1 above may be assigned to one or more Affiliates of Seagen as provided in Section 6.7 in each case so long as Seagen is not relieved of any liability or obligations under this Section 4. Termination of Registration Rights. Seagen’s right to request registration of its Registrable Securities as set forth in Section 4.1 above shall terminate automatically on the date that is five (5) years following the Closing Date or, if earlier, once Seagen, together with its Affiliates, no longer beneficially owns more than 2% of the outstanding shares of common stock of Pieris. 5.
