<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#147;2013 was a transformative year for MacroGenics, with significant clinical, operational and financial accomplishments to advance our mission of
harnessing the power of the immune system to fight cancer and autoimmune diseases,&#148; said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. &#147;With the completion of our initial public offering, the receipt of substantial milestone

the first three dose expansion cohorts of a Phase 1 clinical trial of MGA271. In addition, 2014 should be an important year for our Dual-Affinity Re-Targeting (DART<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP>), or bi-specific, antibody

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">MacroGenics is a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the
treatment of cancer and autoimmune diseases. The Company generates its pipeline of product candidates from its proprietary suite of next-generation antibody technology platforms, which it believes improve the performance of monoclonal antibodies and
antibody-derived molecules. The Company creates both differentiated molecules that are directed to novel cancer targets, as well as &#147;bio-betters,&#148; which are drugs designed to improve upon marketed medicines. The combination of
MacroGenics&#146; technology platforms and antibody engineering expertise has allowed the Company to generate promising product candidates and enter into several strategic collaborations with global pharmaceutical and biotechnology companies.
