4.6 Proxy Statement. None of the information with respect to such Purchaser that such Purchaser or any of its Representatives furnishes in writing to the Company expressly for use in the Proxy Statement, will, at the date such Proxy Statement is first mailed to the Shareholders or at the time of the Shareholders Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

4.12 General Solicitation. Such Purchaser is not purchasing the New Shares to be purchased by such Purchaser as a result of any advertisement, article, notice or other communication regarding such New Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar.

INDEMNIFICATION

8.1 Indemnification. In consideration of each Purchaser’s execution and delivery of this Agreement and acquiring the New Shares hereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Purchaser and all of its Shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, fines, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in this Agreement, (b) any breach of any covenant, agreement or obligation of the Company contained in this Agreement or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company or the Subsidiaries) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the obligations set forth in this Agreement, (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the New Shares, (iii) any disclosure properly made pursuant to Section 5.5 or (iv) the status of such Purchaser or holder of the New Shares as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under Applicable Law. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 8.1 shall be the same as those set forth in

Section 7(c) of the Grifols Registration Rights Agreement or the Other Purchasers Registration Rights Agreement, as applicable.

8.2 Remedies. Subsequent to the Closing, the remedies in this Article VIII shall be the sole and exclusive remedies of the Parties with respect to any breach of the respective representations, warranties, covenants and agreements pursuant to this Agreement or otherwise arising out of this Agreement, regardless of the theory or cause of action pled, except for the remedies of specific performance, injunction and other equitable relief; provided, however, that no Party hereto shall be deemed to have waived any rights, claims, causes of action or remedies, if and to the extent fraud, willful misconduct or intentional misrepresentation is proven on the part of a Party by another Party hereto or such rights, claims, causes of action or remedies may not be waived under Applicable Law. Each Purchaser can separately exercise any of its rights, claims, causes of action or remedies under this Agreement and no waiver or other action by any Purchaser shall be binding on any other Purchaser.

ARTICLE IX

TERMINATION, AMENDMENT AND WAIVER

9.1 Termination of the Agreement. This Agreement may be terminated at any time prior to the Closing, by action taken or authorized by the board of directors of the terminating Party or Parties, and as provided below:

(a) by mutual written consent duly authorized by the boards of directors of Grifols and the Company;

(b) by either the Company or Grifols if the Closing shall not have occurred by November 20, 2013 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 9.1(b) shall not be available to any Party whose action or failure to act has been a principal cause of or resulted in the failure of the Closing to occur on or before such date;

(c) by either the Company or Grifols if a Governmental Entity shall have issued an Order or taken any other action (including the failure to have taken an action) having the effect of permanently restraining, enjoining or otherwise prohibiting the Closing of the consummation of the Transactions, which Order or other action is final and nonappealable;

(d) by Grifols, upon a breach of any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Section 7.3(a) or Section 7.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that if such inaccuracy in the Company’s representations and warranties or breach by the Company is curable by the Company, prior to the Outside Date through the exercise of reasonable efforts, then Grifols may not terminate this Agreement under this Section 9.1(d) prior to 30 days following the receipt of written notice from Grifols to the Company of such breach.

9.2 Termination of Individual Purchasers. The Company may terminate this Agreement with respect to any Purchaser, by action or authorized by the board of directors of the Company, upon a breach of any representation, warranty, covenant or agreement on the part of each applicable Purchaser set forth in this Agreement, or if any representation or warranty of such Purchaser shall have become untrue, in either case such that the conditions set forth in Section 7.2(a) or Section 7.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that if such inaccuracy in such Purchaser’s representations and warranties or breach by such Purchaser is curable by such Purchaser prior to the Outside Date through the exercise of reasonable efforts, then the Company may not terminate this Agreement under this Section 9.2 prior to 30 days following the receipt of written notice from the Company to such Purchaser of such breach. For the avoidance of doubt, the Company’s exercise of its termination rights under this Section 9.2 would terminate the rights and obligations of the Company and the applicable Purchaser solely with respect to such Purchaser and shall have no effect on the rights and obligations of any other Purchaser under this Agreement.

9.3 Notice of Termination; Effect of Termination. Any termination of this Agreement under Section 9.1 or 9.2 above shall be effective immediately upon the delivery of a valid written notice of the terminating Party to the other Party hereto. In the event of the termination of this Agreement as provided in Section 9.1, this Agreement shall be of no further force or effect, except (i) as set forth in Section 5.2(a), Section 5.9, this Section 9.3, Section 9.4 and Article X, each of which shall survive the termination of this Agreement and (ii) nothing herein shall relieve any Party from liability for any breach of this Agreement.

9.4 Expenses. All fees and expenses incurred in connection with this Agreement and the Transactions, including fees and expenses of financial advisors, financial sponsors, legal counsel and other advisors, shall be paid by the Party incurring such expenses whether or not the Transactions are consummated.
