Ladies and Gentlemen:

     We have acted as special counsel in the Commonwealth of Virginia to Grifols Inc., a Virginia corporation (the “Company”), in connection with the registration, pursuant to a registration statement on Form F-4 (as may be amended from time to time, the “Registration Statement”), filed with the United States Securities and Exchange Commission (the “SEC”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), on the date hereof by Grifols, S.A., a company organized under the laws of the Kingdom of Spain (“Parent”), the Company and the other subsidiaries of Parent listed on Exhibit A hereto (the “Subsidiary Guarantors”), of (i) $1,100,000,000 aggregate principal amount of the Company’s 8.25% Senior Notes due 2018 (the “Exchange Notes”) and (ii) the guarantees of the Company’s obligations under the Exchange Notes by Parent and the Subsidiary Guarantors (the “Guarantees”). The Exchange Notes are to be issued in exchange (the “Exchange Offer”) for an equal aggregate principal amount of the Company’s unregistered 8.25% Senior Notes due 2018 (the “Existing Notes”) originally issued by Giant Funding Corp., an escrow company (the Escrow Issuer”) on January 21, 2011, and assumed by the Company and guaranteed by the Parent and the Subsidiary Guarantors effective as of June 1, 2011, in reliance on an exemption from registration under the Securities Act for offers and sales of securities not involving public offerings. The Exchange Notes and the Guarantees (collectively, the “Securities”) will be issued pursuant to the terms of that certain Indenture dated as of January 21, 2011 (the “Base Indenture”) by and between the Escrow Issuer and The Bank of New York, Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Supplemental Indenture dated as of June 1, 2011 (the “First Supplemental Indenture”) and the Second Supplemental Indenture dated as of October 4, 2011 (the “Second Supplemental Indenture” and, together with the Base Indenture and the First Supplemental Indenture, the “Indenture”), by and among Parent, the Company, the Subsidiary Guarantors party thereto and the Trustee. The terms of the Exchange Offer are described in the Registration Statement. Capitalized terms used but not otherwise defined herein have the meanings given to them in the Indenture.
