-- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) ("Armata"), a clinical-stage biotechnology company focused
on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections, today announced that the previously-announced
merger between C3J Therapeutics, Inc. ("C3J") and AmpliPhi Biosciences Corporation (NYSE American: APHB) ("AmpliPhi")

"We are pleased to have consummated this merger between
C3J and AmpliPhi combining each company's complimentary and unique strengths and, we believe, creating an undisputed leader
in the development of bacteriophage therapeutics to combat the increasingly urgent crisis of antibiotic resistance," stated
Todd R. Patrick, Chief Executive Officer of Armata. "With a Phase 1b/2-ready lead asset, an extensive synthetic phage library,
and world-class, phage-specific GMP manufacturing facilities that can efficiently advance new candidates into the clinic, we bring
a unique set of capabilities that clearly set us apart. Further, we believe we have the leadership team and financial resources
in place to advance our novel pipeline of natural and synthetic phage-based candidates through meaningful and potentially value-creating
milestones. With the merger now completed, we are working diligently toward that goal."
Armata's innovative pipeline of bacteriophage therapeutic
candidates includes:
Concurrent with the closing of the merger, an investor syndicate
comprised of certain existing C3J shareholders invested $10 million into Armata, bringing the Company's cash balance to approximately
$16 million. The financing proceeds, together with cash on hand, will be used to advance the combined company's preclinical
and clinical programs and for other corporate and general purposes.

financing have not been registered under the Securities Act of 1933, as amended, or state securities laws and may not be offered
or sold in the United States absent registration with the Securities and Exchange Commission or an applicable exemption from such
registration requirements. Armata has agreed to file a registration statement with the Securities and Exchange Commission
covering the resale of the above-mentioned securities.
In connection with the closing of the merger, AmpliPhi completed
a one-for-fourteen reverse stock split. As a result of the reverse stock split, every fourteen shares of AmpliPhi common stock
outstanding immediately prior to the merger were combined and reclassified into one share of AmpliPhi common stock.
As a result of the closing of the merger and the concurrent
financing, the C3J shareholders, after taking into account the issuance of shares in the financing, now own approximately 76%,
and AmpliPhi's current shareholders now own approximately 24%, of Armata's common stock.
