Exhibit 10.74

BUSINESS TRANSFER AGREEMENT

This BUSINESS TRANSFER AGREEMENT (this “Agreement”) is made and entered into on February 28, 2006 by and among MOLECULAR IMAGING CORPORATION, a Delaware corporation (“MIC”), MOLECULAR IMAGING CYCLOTRON LLC, a Delaware limited liability company (“MIC LLC” and, with MIC collectively, the “MIC Parties”), and P.E.T.NET PHARMACEUTICALS, INC., a Tennessee corporation doing business as PETNET SOLUTIONS (“PETNET”).

BACKGROUND

A. MIC LLC has operated a facility for the production of Biomarkers (as defined in Section 6.01 hereof) at 11388 Sorrento Valley Road, San Diego, CA 92121 (the “Facility”), and has made payments to UCSD for equipment provided by the Regents of the University of California, a California constitutional corporation acting on behalf of its San Diego campus (“UCSD”) certain assets required for the operation of the Facility to produce Biomarkers (the “Assets”).

B. On the Effective Date, PETNET has acquired the Assets from UCSD and has entered into a commercial lease for the Facility with BC Sorrento, LLC, the landlord for the Facility.

C. The MIC Parties and PETNET desire to resolve certain issues relating to the winding-up of the business conducted by MIC LLC from the Facility and the relationship between PETNET and the MIC Parties from and after the Effective Date (as defined in Section 5.01 hereof).

AGREEMENT

THEREFORE, in consideration of the mutual benefits to be derived therefrom and of the respective mutual covenants and agreements hereinafter set forth, the MIC Parties and PETNET (each, a “Party”; collectively, the “Parties”) hereby agree as follows:

1. Business Transfer

From and after the Effective Date, MIC LLC hereby unconditionally and absolutely assigns, transfers, sets over, and conveys to PETNET all of MIC LLC’s right, title, and interest in, to and under each of the Contracts (as defined in Section 6.01 hereof), and the outstanding offers or solicitations made by or to MIC LLC to enter into any Contract, identified on Schedule I hereto (the “Assigned Contracts”) , free and clear of all Encumbrances. MIC LLC agrees that PETNET has the right to negotiate settlements on behalf of MIC LLC for “back-up” doses MIC was obligated to provide under the “Assigned Contracts”.

From and after the Effective Date, PETNET hereby unconditionally and absolutely (a) accepts the assignment of MIC LLC’s rights, titles, and interests as set forth in Section 1.01 hereof; and (b) assumes and agrees to satisfy and discharge, as they become due, all liabilities under the Assigned Contracts. PETNET also has the right to renegotiate the Assigned Contracts with terms favorable to PETNET.

As additional consideration for the assignment of the Assigned Contracts, PETNET agrees to pay MIC LLC, or its assignees, a royalty of five percent (5%) of Net Sales of Biomarkers to the former MIC customers identified on Schedule II hereto (the “Protected Customers”) during the period beginning on the Effective Date and ending on the third anniversary thereof (the “Post-Transfer Period”). For purposes of this Section 1.03, “Net Sales” means total revenues received by PETNET from the sale of Biomarkers to the Protected Customers, less (a) rebates or refunds paid; (b) credits for claims, allowances, recalls or returns for spoiled, damaged or outdated goods (excluding any obligations assumed by PETNET as provided in Section 2.03); (c) license fees or taxes paid or due any third party in connection with the sale of Biomarkers; and (d) transportation costs. Upon written notice to

EXHIBIT A

1

PETNET, MIC LLC may assign to its members the right to receive the royalty payments under this Agreement, and PETNET shall make such payments as provided in such notice.

As additional consideration for the assumption of the Assigned Contracts, MIC hereby agrees that, during the Post-Transfer Period, neither the MIC Parties nor their Affiliates (as defined in Section 6.01 hereof) (a) shall have an equity interest in a Person that provides commercial Biomarkers to MIC Parties or (b) shall enter, directly or indirectly, into any agreement or arrangement with any Person (as defined in Section 6.01 hereof) other than PETNET or its Affiliates for, or invest in, own shares in or lend money to any Person involved in, the production, distribution or sale of commercial Biomarkers within the United States of America. Upon any Person becoming entitled to exercise control, as that term is defined in Section 6.01(a) hereof, over more than 50% of the outstanding capital stock or other securities entitled to vote in the election of directors of MIC, or the sale of all or substantially all of the assets of MIC to a Person who was not an Affiliate of MIC immediately prior to the closing of such transaction (a “Change of Control”), MIC shall have the right to terminate the provisions of this Section 1.04, upon written notice to PETNET on or after the closing of the transaction that results in a Change of Control.

2. Additional Agreements

Immediately following the execution of this Agreement, MIC LLC shall take all steps necessary to put PETNET, its successors or assigns, in actual possession and operating control of the Assigned Contracts, including but not limited to delivery to PETNET of the original versions or true copies of all such Assigned Contracts.

Upon PETNET’s written request, MIC LLC shall arrange to provide consultative radiation protection services to PETNET to support the transfer of MIC LLC’s radioactive materials (“RAM”) license obligations to PETNET while PETNET applies for and obtains its own RAM license and registration for the Cyclotron. In the event that PETNET wishes to obtain such services, MIC LLC and PETNET will enter into a services agreement for the services on mutually agreeable terms and conditions.

MIC LLC and PETNET acknowledge that MIC LLC has a historical financial obligation to MIC LLC’s FDG customers for FDG purchased from other suppliers when MIC LLC was unable to provide FDG. For each customer, the amount of this obligation is set forth on Schedule III hereto. MIC LLC agrees that PETNET will act on its behalf in negotiating settlements to MIC LLC’s former customers in accordance with the applicable provisions of the Assigned Contracts.

From December 5, 2005 to the Effective Date (the “Transition Period”), PETNET has supplied and will supply Biomarkers to MIC customers, including the Protected Customers. MIC and PETNET agree that PETNET shall retain all revenues received by PETNET for such sales of Biomarkers, and the provisions of Section 1.03 shall not apply to such sales.

Not later than 30 days after December 5, 2005 and each month thereafter until the first to occur of (x) the Closing or (y) the mutual termination of discussions regarding the Contemplated Transactions, PETNET shall pay MIC LLC the amount of MIC LLC’s out-of-pocket expenses for the operation of the Facility during the Transition Period. PETNET and MIC agree that such expenses are equal to $24,596 per calendar month or portion thereof from December 5, 2005 to January 31, 2006, and $20,022 per calendar month or portion thereof after January 31, 2006, during the Transition Period, and that this amount represents the daily cost of:

(a) The salaries and benefits costs of two full-time employees employed by MIC for the operation of the Facility; and

EXHIBIT A

2

(b) The pro rata portion of the total lease and utility expenses incurred by MIC for the entire Facility attributable to the portion of the Facility used for the production of Biomarkers.

On the Effective Date, PETNET and MIC shall enter into one or more Confidential Biomarker Supply Agreements, in substantially the form attached hereto as Exhibit A (the “Supply Agreements”), providing for MIC to purchase clinical Biomarkers (as defined in Section 6.01 hereof) exclusively from PETNET after the Closing Date. For supply of Biomarkers to locations within the San Diego Market (as defined in Section 6.01 hereof), the price of FDG in any Supply Agreement shall not exceed the price of $190 per dose for a 1-15 mCi dose, with a periodic negotiation of such pricing after January 1, 2007. For supply of Biomarkers to locations not within the San Diego Market, (a) PETNET shall present MIC with a proposed Supply Agreement including commercial Biomarker pricing; (b) MIC shall accept the Supply Agreement or provide evidence satisfactory to PETNET of lower competitive pricing available to MIC from PETNET competitors (which lower competitive pricing shall be the total as-delivered price of Biomarkers); (c) if MIC provides such evidence, PETNET shall have the unilateral option to meet the competitor’s price; and (d) if PETNET elects to meet the competitor’s price, then MIC shall accept the Supply Agreement and such lower price. The provisions of this Section 2.06 shall apply to each Covered Scanner (as defined in Section 6.01 hereof) now owned or operated by MIC or acquired or operated by MIC during the Post-Transfer Period. PETNET shall have no obligation to supply a specific Biomarker to any location operated by MIC if PETNET does not routinely supply such Biomarker from a PETNET facility within reasonable proximity to the MIC location. Each Supply Agreement shall provide that MIC may terminate such Supply Agreement in the event of any Change of Control, upon written notice to PETNET on or after the closing of the transaction that results in a Change of Control. Upon written notice thereof to PETNET, MIC may fulfill its rights and obligations under this Section 2.06 through any Affiliate, with the result that a Supply Agreement would be entered into by PETNET and the specified Affiliate. MIC shall not be deemed to have breached its obligations under this Section 2.06 by virtue of any Contract for the purchase of Biomarkers by MIC from any Person other than PETNET that is in force on the date of this Agreement; provided, that MIC shall use its commercially reasonable efforts to terminate any such Contract at the first commercially reasonable opportunity.

On the Effective Date, PETNET and MIC shall enter into a Sublease (the “Sublease”) pursuant to which PETNET shall lease to MIC, and MIC shall lease from PETNET, a designated portion of the Facility which may be used by MIC as its corporate headquarters and for certain of its medical imaging operations as mutually agreed, substantially in accordance with the terms set forth on Schedule IV. The Parties estimate that PETNET will occupy approximately 33% of the total available space in the Facility. MIC’s leased area will be approximately 53% of the total leased space
