 1.2    Assumed Liabilities; Retained Liabilities. 

(a) Buyer shall not assume or be liable for any Liabilities other than as expressly provided for in this Section 1.2. Buyer shall not
assume or be liable for any Liabilities, Indebtedness or other obligations of whatever nature of Seller which relate to Photrex or other Miravant Derived Photodynamic Therapy programs prior to the Closing Date, including sales or distribution of
drugs, equipment or consumables made prior to the Closing Date that are used or consumed after the Closing Date, any replacement, warranty or service claims relating to such sales or distribution, past clinical or nonclinical studies or prior
financial obligations or judgments made against Miravant or one or more Miravant Subsidiaries. Notwithstanding the foregoing: 

(i) in order to expedite this overall process and consistent with the Option Agreement, Seller has previously authorized Buyer,
at Buyer’s cost using Buyer’s choice of counsel, to attend to the finalization of the foreclosure related transfer of ownership of the Acquired Assets to Seller by covering Seller’s expenses pertaining to the foreclosure and the
repossession followed by the disposition of collateral as provided herein up to an amount not to exceed $15,000 (of which $10,000 has heretofore been paid to Seller) with the remaining $5,000 payable upon the Effective Date; and 

(ii) Buyer shall advance all out of pocket fees and expenses of Seller’s counsel in the amount of $1,000 for transfer of
patents listed in Annex 1 from Miravant’s name to Seller’s name, from Miravant Subsidiaries’ names to Seller’s name, and subsequently from Seller’s name to Buyer’s name. 

(iii) Buyer shall, at Buyer’s cost using Buyer’s choice of counsel, attend to the recovery/transfer of Miravant
corporate documents, as necessary for transfer of the Acquired Assets to Buyer. 
 (b) At the Closing, on the terms and subject to the
conditions set forth in this Agreement, the Buyer expressly assumes, the “Assumed Liabilities” and no other Liabilities. The “Assumed Liabilities” are to be paid on a contingency basis according to the rate set by the
Financing Payment Schedule. The “Assumed Liabilities” are: 

  
 2 













 (i) legal fees and expenses of Seller incurred in connection with the
transactions contemplated by this Agreement, plus past unpaid patent related expenses of Seller, up to a maximum amount of $40,000. 

(ii) On Seller’s behalf, Buyer shall pay Steven J. Rychnovsky $13,000 in cash for past expenses payable. 

(c) All other Liabilities, independent of the Assumed Liabilities, are retained by Seller (the “Retained Liabilities”). 

1.3    Purchase Price. The purchase price to be paid by Buyer for the Acquired Assets shall be as follows (the
“Purchase Price”): 
 (a)     

(i) At the Closing, Buyer or Buyer Licensee will deliver to Seller a $100,000 aggregate principal amount in the form of a
convertible equity security (“Convertible Equity Security”) and will also deliver to Steven J. Rychnovsky as Seller’s Designee, a $100,000 aggregate principal amount in the form of a second Convertible Equity Security. The
combined total amount of all such Convertible Equity Securities will be $200,000 and will fully satisfy that $200,000 convertible debenture referenced in that Option to Purchase Assets Agreement, dated August 27, 2009, by and between Seller and
Buyer. Each Convertible Equity Security shall carry a simple interest rate of 8% accruing from the Effective Date and shall be converted (including any interest that is accrued and unpaid as of the date of conversion) on the date of the Payment
Equity Financing of (A) the Buyer or (B) the Buyer Licensee. This conversion shall be the sole means of payment of the Convertible Equity Security, unless at Buyer’s sole discretion, Buyer chooses to pay cash in whole or in part. 

(ii) Buyer or Buyer Licensee will pay an initial contingency based milestone payment totaling $100,000 in cash (the
“Initial Milestone Payment”) to Seller and Seller’s Designee according to the rate, payment structure and contingency conditions set by the Financing Payment Schedule. 

(iii) Prior to complete payment of the Initial Milestone Payment and complete payment of the Assumed Liabilities the Buyer
agrees to use commercially reasonable efforts to maintain the Acquired Assets in good standing such that in the event of termination, all Acquired Assets may be returned to the Seller. However, it is the Buyer’s responsibility to maintain all
patents at the Buyer’s sole discretion and the Buyer may choose, at its sole discretion, to abandon any patents included in the Acquired Assets and those abandoned patents need not be returned to the Seller upon termination. 

(b) Unless earlier terminated, either Buyer or the Buyer Licensee, but not both, shall pay Seller the following milestone payments (each a
“Development Milestone Payment”) within sixty (60) days after achievement of the indicated milestone event (each a “Development Milestone Event”) by Buyer or Buyer Licensee with respect to a Product: 

  
 3 













 (i) a total of $300,000 in cash, with $240,000 paid to the Seller and
$60,000 paid to the Seller’s Designee, upon the sooner of (A) the next equity financing after a “non-exploratory clinical trial” (a Phase IIB trial in which at least 50 patients that
complete the trial and their clinical data can be evaluated) or (B) the commencement of a clinical trial intended to be used as a definitive study for market approval in any ‘country; and 

(ii) and a total of $700,000, with $560,000 paid to the Seller and $140,000 paid to the Seller’s Designee, upon the grant
of the first Regulatory Approval of a Product. 
 (iii) For avoidance of doubt, each of the foregoing Milestone Payments
shall become due and payable, if at all, (A) solely in connection with the performance or achievement of the relevant Development Milestone Event in relation to a Product that is developed through the material use of the Acquired Assets,
(B) the first time such Development Milestone Event is achieved, whether it is achieved by Buyer or any Buyer Licensee, and (C) a maximum of one (1) time regardless of how many times any specific Development Milestone Event is
achieved with Products and regardless of the payor. 
 (c) Unless earlier terminated, either Buyer shall pay, or any Buyer Licensee shall
pay, but not both, to Seller a single royalty equal to six percent (6.0%) of Net Sales during the Royalty Term and shall pay to Seller’s Designee a single royalty equal to one and one-half percent (1.5%)
of Net Sales during the Royalty Term. Buyer Licensee shall pay the royalty directly or indirectly through Buyer. The payments due under this Section 1.3(c) shall be paid within thirty (30) days of the end of each calendar quarter during
which revenue is collected. Royalties on Net Sales under this Section 1.3(c) will be payable on a Product-by-Product and country-by-country basis, commencing on the first commercial sale of a Finished Product in a country until the later of (i) the invalidation, revocation, lapse or expiration of the last to expire Valid
Claim of any Patent that would be infringed by the sale of such Finished Product in such country or (ii) the expiration of any Regulatory Exclusivity Period for such Product in such country (the “Royalty Term”). The Royalty
Term will include only that period for which the Buyer, Buyer Licensee or their designee, holds exclusive marketing rights in the relevant . jurisdiction for the Acquired Assets, or products derived from the Acquired Assets, as a result of a legal
right received as part of this Asset Purchase Agreement by Data Exclusivity, Orphan Drug Exclusivity or Patent Protection. However, patents which may be in force but which do not provide marketing exclusivity will not be included in the
determination of royalties to be paid to Seller under this agreement. 
 1.4    Delivery of Acquired Assets.
Buyer shall take possession of all Acquired Assets, wherever located, on the Closing Date. 
 1.5    The Closing.
Subject to the satisfaction of the conditions precedent to the Closing set forth in Article IV, the Closing of the transactions contemplated by this Agreement (the “Closing”) shall, unless the parties otherwise agree in writing,
take place at a location of the Buyer’s choosing within three (3) Business Days of the satisfaction of all of the conditions precedent to the Closing set forth in Article IV (or waiver of any such condition by Buyer in accordance with the
terms hereof), or such other location or date as the Parties may mutually agree. The date on which the Closing actually occurs is referred to in this Agreement as the “Closing Date.”

transfer, convey, assign and deliver to Buyer, and to confirm Buyer’s rights to, title in and ownership of, the Acquired Assets, and to place Buyer in actual possession and operating control thereof, including the furnishing of information and
execution of any documents, the filing or recordation of which with Governmental Entities, including the United States Patent and Trademark Office, is prerequisite to the statutory establishment or recordation of assignment of any patents,
copyrights or trademarks included in the Acquired Assets. The Parties shall cooperate in activities associated with the sale, transfer, conveyance, assignment and delivery of the Acquired Assets to Buyer and with the purchase of the Acquired Assets
by Buyer. With Seller’s cooperation, Buyer shall, at Buyer’s cost and using Buyer’s choice of counsel, record in the records of the requisite Governmental Entities the series of transfers of the Acquired Patents and Regulatory

period (or portion thereof) beginning after the Closing Date; or (5) involves a claim for which an adverse determination would have a material and adverse effect on the Indemnified Party’s reputation or future business prospects. If notice
of intent to dispute and defend is not given by the Indemnifying Party within the time period referenced above, or if such diligent good faith defense is not being or ceases to be conducted, then the Indemnified Party may undertake the defense of
(with counsel selected by such Indemnified Party), and shall have the right to compromise or settle, such Third Party Claim (exercising reasonable business judgment) in its discretion. If such Third Party Claim is one that, by its nature, cannot be

part of an Acquired Patent described in clause (i), then (w) such claim will again be considered to be a Valid Claim effective as of the issuance of such Acquired Patent, (y) Buyer or Buyer Licensee will be notified of such issuance, and
(z) any royalty payments under this Agreement payable as a result of such later-issued claim will be payable only after the effective date of such issuance, and will not be obligated for any royalty payments retroactive to the date such claim
ceased to be a Valid Claim under clause (ii) due to the passage of time.
