the following:
           You state on page 66 that you are currently in litigation with
Veneto regarding the
             assets and business transferred, many of the contractual
arrangements you assumed
             have been terminated, and you have had to rebuild the business
relationships and the
             structure of the contractual relationships you took over from
Veneto. You also state
             on page 45 that the MSO was built through relationships between
physicians and the

              You state on page 69 that the arbitration action alleges that
Veneto never transferred
              the ownership rights in at least one pharmacy to NDS and that
pharmacy was a
              necessary element in the operation of other assets transferred by
Veneto.
           You state on page 94 that certain assets were never transferred due
to regulatory
              impositions and that NuGenerex is not responsible for repayment
of a loan on assets
              not transferred.
           You state on page 85 that in March 2019 you changed your business
model to no
              longer utilize their existing pharmacies which resulted in you
breaking your existing
              lease agreements with your pharmacies. In this respect we note
your disclosure on
              page 95 which states that $292,681 of disposals pertain to Veneto
and was mostly the
              result of your shift in business operations during March 2019.
         You disclose on page 105 that you revalued the assets during the
measurement period in
         accordance with ASC 805-10-25-14 and reduced goodwill accordingly.
However your
         disclosure, as noted above, appears to imply that the assets recorded
may need further
         consideration, including potentially an impairment for events
occurring after the
         acquisition date such as the change in your business model. Please
provide us your
         analysis regarding the valuation of the assets recorded in connection
with the Veneto
         acquisition, including goodwill. Your analysis should at a minimum
include the
         following:
           the nature of each significant asset acquired in the acquisition,
           the status of ownership and rights for each significant asset at the
time of the
              acquisition and at your balance sheet date,
           how each asset was affected by your change in business model,
           how each asset was affected by any terminated contractual
arrangements,
           the extent to which you have had to rebuild business relationships,
including the
              network of physician partners in the MSO acquired from Veneto,
and
           the effect of the ongoing litigation with Veneto
Note 13 - Acquisitions
Veneto, page 104

9.       You appear to consolidate the assets acquired of Veneto. You state on
page 45 the MSO
         acquired from Veneto is named Rapport Services, LLC ("Rapport"), which
is a physician-
         owned limited liability company (or LLC) requiring an at-risk equity
investment from
         physicians or physician groups that wish to participate in the
network. The Rapport
         physician investors own 99% of Rapport, and Generex (through your
wholly-owned
         subsidiary NuGenerex Distribution Solutions 2) owns 1% and serves as
the managing
         director of the LLC. Please provide us with your analysis as to why
consolidation is
         consistent with ASC 810. If Veneto is not considered a variable
interest entity, please
         provide your assessment of consolidation under the entities controlled
by contract in ASC
         810-10-25-60.

complete the
             projects, and the anticipated completion dates.
           the risks and uncertainties associated with completing development
on schedule, and
             consequences if it is not completed timely.
           what appraisal method was used to value the projects.
           the significant appraisal assumptions, such as:
               o  the period in which material net cash inflows from
significant projects are
                  expected to commence;
               o  material anticipated changes from historical pricing, margins
and expense
                  levels; and
               o  the risk adjusted discount rate applied to the project's cash
flows.
           In periods subsequent to the purchase of significant in-process
research and
             development, tell us the status of efforts to complete all of your
significant in-process
             research and development projects, including those other than the
assets acquired in
             the Olaregen and Regentys acquisitions, and the impact of any
delays on your
             expected investment return, results of operations and financial
condition.

promissory note. In
         August 2019, subsequent to your balance sheet date, your interest
increased to 76%.
