Dear
Craig:

Thank
you for your prompt responses to earlier versions of our proposal. As discussed, Nace Pharma, LLC ("Nace") is prepared to enter into an agreement with Provectus
Pharmaceuticals, Inc. ("Provectus") to represent your company as its agent authorized to solicit offers to license or options to license its products to the pharmaceutical companies listed in
Exhibit A. In order to strike a fair balance between your reasonable desire not to be tied to an "exclusive" representation arrangement with Nace Pharma and our objective to be fairly
compensated for an initiative of our which results in a license or option to license agreement of Provectus new chemical entity, we agree as follows:

If
Nace introduces Provectus to one or more of the companies on Exhibit A, and if our introduction leads to a meeting between Provectus and the prospect and the execution of a
Provectus CDA by the prospect, then and only then would we be "protected" with respect to that particular company for a period of two years from the date of the CDA, or until the Nace Pharma contact
declines the technology, whichever is sooner.

The
intention of the parties is to leverage the relationships developed by Dr. Michael H. Davidson and Stuart Fuchs, the members of Nace, to the benefit of Provectus. As
founder and CEO of the Chicago Center for Clinical Research, one of the largest site management organizations, Dr. Davidson has developed professional and social ties to a large number of CEOs
and research director of Big Pharmas and other ethical drug companies, and has served as Principal Investigator or advised on numerous clinical trials. Stuart Fuchs has since 1995 been involved in
funding several biotech companies, particularly in the field of cancer therapeutics. Formed in 1997, Nace Pharma seeks to bridge the chasm between the innovative biotech companies like Provectus and
pharmaceutical companies interested in augmenting their pipeline of drugs in development by in-licensing promising new chemical entities.

The
subject of our agreement is XANTRYL and PROVECTA, pharmaceutical compositions based on a common halogenated xanthene, and related chemical entities ("XANTRYL" and
"PROVECTA") which employ one or more of the following techniques:



Other
new chemical entities discovered by Provectus could be included in our agreement by mutual agreement of the parties.

Provectus
agrees to reimburse Nace for travel and other reasonable out-of-pocket expenses actually incurred in connection with our solicitation efforts on behalf
of Provectus pursuant to this agreement; provided, however, that any reimbursable expense in excess of $1,000 are subject to prior approval in writing by Craig Dees or other duly authorized officer of
Provectus.

Nace's
fees would consist of the following:

Upfront Warrants

In order to provide Nace with the incentive to get started, Provectus agrees to grant Nace upon the signing of this Agreement 3 year warrants to purchase
100,000 shares of restricted common stock at an exercise price equal to the weighted average price of the stock over the preceding 30 trading days. The warrants would include "piggyback" registration
rights, but would vest only upon the signing of the initial transaction with one of the companies listed on Exhibit A in an estimated amount of no less than $10 million dollars. For
purposes of this paragraph only, the estimated value of the contract will be based upon revenues of any kind, including all fees, joint development expenses, payments in kind and work in kind.

Cash Fees

In addition, Nace would earn 2.5% of the first $50 million of any cumulative revenues paid to Provectus by any of the potential licensees listed on
Exhibit A, and 5.0% of any cumulative revenues above $50 million. For purposes of this paragraph, "revenues" are defined to include milestone payments and exclude any work in kind or
payments in kind, as well as any amounts paid to Provectus pursuant to joint development contracts. The case fees earned by Nace are due and payable within thirty (30) days of the actual
receipt by Provectus of revenues as defined in this paragraph.

If
this proposal is acceptable to you, please sign in the appropriate space. In order to introduce you and other members of the Provectus management team to Dr. Michael Davidson,
I'd be delighted to arrange a meeting or conference call at a mutually convenience time and place.

Thanks
again for your kind consideration. Michael and I look forward to a long and mutually profitable association with Provectus Pharmaceuticals.

Sincerely,

|/s/STUART FUCHSStuart Fuchs |  |
