   1.                                                   We note your statement
that third-party sources contain information from sources believed
                                                        to be reliable but
there are no assurances as to the accuracy or completeness of

   2.                                                   We note your statement
here and elsewhere in your prospectus that you have "two
                                                        platform drugs."
Because FDA approval is dependent on the agency making a formal
                                                        determination that a
product candidate is safe and effective, it is premature to describe

revise these statements
         to make clear that RP5063 and RP1208 are drug candidates or product
candidates.

3.       We note your disclosure that it is intended that the domestication and
business
         combination will constitute tax free reorganizations. Please clarify
that with respect to the
         domestication, there is uncertainty as to the tax treatment due to the
absence of guidance
         of how the applicable provision of the code applies to a company in
your circumstances.
         With respect to the business combination, identify the factual matters
you are currently
         not able to determine and indicate how you believe it should be
treated for tax purposes
         and what assumptions that treatment is based on.
Questions and Answers
What is the form of consideration that shareholders of Reviva will receive in
return for the
acquisition of Reviva by Tenzing?, page 21

4.       Please clarify your estimate that Reviva's shareholders will hold
approximately 52.99% of
         the combined company's common stock in the aggregate assumes, among
other things,
         that no Tenzing shareholders exercise their redemption rights with
respect to their
         ordinary shares.

Pro Forma Adjustments to the Unaudited Combined Balance Sheet, page 32

5.       With regards to adjustment five for scenario two, please revise the
note to reconcile the
         redemption amount of $21,253,077 to the amount in the pro forma
combined balance
         sheet on page 31 of $19,953,077.
Pro Forma Adjustments to the Unaudited Combined Statements of Operations, page

6.       With regards to adjustment four, please reconcile the weighted average
shares outstanding
         at scenarios one and two to those presented in the pro forma combined
statements of
         operations on pages 33 and 34.
Some of Tenzing's officers and directors may be argued to have conflicts of
interest..., page 39

7.       Please expand your discussion to disclose the officers' and directors'
aggregate average
         investment per share. In addition, clarify that in addition to
Tenzing's officers and
         directors being at risk to lose their entire investment if the
transaction is not approved,
         their significantly lower investment per share in their Tenzing shares
results in a
         difference between a transaction that increases the value of the
officers' and directors'
         investment and a transaction that increases the value of the public
shareholders'
         investment.

8.       Please include a separate risk factor addressing the potential
consequences resulting from
         the potential waiver of conditions to the merger.
Risk Factors
There is a risk that a U.S. Holder may recognize taxable gain with respect to
its Tenzing Shares
at the effective time of the Domestication., page 42

treatment assuming the
         domestication is determined not to be taxable.
Representations and Warranties, page 100

10.      Please expand your discussion to describe the representations and
warranties. For
         example, what has Reviva represented or warrantied with respect to
capitalization,
         permits, litigation, contracts, etc.?

11.      Please identify the closing conditions that are subject to waiver.

12.      Please expand your discussion with respect to each of the targeted
companies that resulted
         in a firm offer. In these instances, disclose the initial offer, and
counter offers.
13.      Please revise the fourth paragraph on page 117 to disclose the
material terms proposed in
         the draft term sheet you delivered to Dr. Bhat and discuss how the
terms changed during
         the course of the negotiations.
14.      Please identify any meetings where Dr. Bhat's employment by the
combined company
         was discussed.
15.      It appears that you entered into an exclusivity agreement with Reviva
while you were near
         completion on a definitive agreement with Company F. Please explain
how the pending
         terms in your negotiation with Company F compared to the terms of your
         negotiations with Reviva, whether the ongoing negotiations were an
exception of the
         exclusivity agreement or if the negotiations with Reviva were a factor
in terminating your
         discussions with Company F.

16.      Please revise your disclosure here and throughout the prospectus to
eliminate any
         suggestion that Reviva's product candidates have been or will
ultimately be determined
         safe or effective, as only the FDA and foreign government equivalent
regulators have the
         authority to make these determinations. For example, we note your
disclosure on page 119
         that

                "[RP5063] has demonstrated clinical efficacy and safety for
schizophrenia and
              schizoaffective disorders."
             "RP5063 also showed efficacy for pulmonary arterial hypertension
(PAH) and
              idiopathic pulmonary fibrosis."
         In addition, we note your discussion at the bottom of page 193 when
you state
         that "RP5063 showed robust efficacy" and again on page 203 when you
state "RP5063
         demonstrated robust efficacy for IPF compared to these standards."

         Delete these statements indicating the trials have demonstrated safety
and/or efficacy.
         You may include a summary of the objective data resulting from the
trials without
         presenting yours conclusion(s) about safety and efficacy.
17.      We note you disclosure that "the Board was persuaded by RP5063
clinical profile that it
         increases the probability of the product being the first in line for
therapy" and your
         disclosure that RP5063 is "first-in-class." Given the stage of
development, and your
         acknowledgement that obtaining FDA approval is inherently uncertain,
these statements
         are speculative and inappropriate. Please revise your registration
statement accordingly. .
18.      We note your disclosure in the financial statements and in your
question and answer
         section that you will pay transaction expenses incurred in connection
with the Business
         Combination, including deferred IPO underwriting fees to your
investment bankers. In
         addition, we note your disclosure that certain "representatives of
Tenzing" conducted
         business and financial diligence and negotiated that term sheet with
Reviva. Please
         disclose whether or not any of your representatives that were part of
the diligence or
         negotiations with Reviva are owed or entitled to any of the deferred
IPO underwriting
         fees.

the quantitative
         and qualitative factors, including previous offers received by Reviva.

21.      Please provide your analysis as to why you are not required to
unbundle those changes to
         your charter which are not specific to special purpose acquisition
companies into separate
         proposals. Refer to Rule 14a-4(a)(3) of Regulation 14A as well as

Information About Reviva Pharmaceuticals, Inc., page 189

23.      With respect to your pipeline table on page 189, it appears that you
identified an unnamed
         product candidate for a "Sleep Disorder" program that just entered the
preclinical stage,
         but do not disclose any additional details on the product candidate
elsewhere in the
         prospectus. To the extent this is a unique material product candidate
or program, please
         discuss it individually. Product candidates and programs that are not
material to your
         current operations should not be included in your pipeline table.
24.      Please revise your pipeline table to reduce the length of the arrows
for your product
         candidates to correspond to their actual stage of development. As one
example, we note
         that the arrows indicate that you have began Phase 3 trial for RP5063
for schizophrenia,
         but your disclosure indicates that you plan to initiate a Phase 3
trial and have not yet
         commenced it.

25.      Please revise your graphics throughout as applicable so that the text
is legible. For
         example, Figure 4 and Figure 6 on pages 194 and 196, respectively
contain text that is
         unclear and difficult to read.

26.      We note your disclosure throughout this section that you have certain
U.S. patents and
         pending patent applications as well as patents and pending patent
applications in "foreign
         countries." Please revise this section to specifically identify all
material foreign
         jurisdictions where patents are granted or patent applications are
pending and also include
         the patent expiration dates and expected expiration dates for pending
patent applications
         for each material foreign jurisdiction.

27.      We note that Reviva focuses its resources on research and development
activities. We also
         reference the table for development status of Reviva's product
pipleline portfolio on page
         190. It's not apparently clear from the table or the disclosures, the
current phase of clinical
         development that each product candidate is in or how the Company
tracks R&D
         expenses. Please revise disclosures to provide the following
information:
             For your key research and development projects, please disclose
the following:
                o   The current status of the project;
                o   The costs incurred during each period presented and to
date;

                 o The nature of efforts and steps necessary to complete the
project;
                 o The extent and nature of additional resources that need to
be obtained if current
                   liquidity is not expected to be sufficient to complete the
project; and
                o  Whether a future milestone such as completion of a
development phase, date of
                   filing an NDA with a regulatory agency, or approval from a
regulatory agency
                   can be reliably determined.
                For the remainder of projects not considered individually
significant, tell us the
              composition of the total R&D expense for each period presented.
This can take a
              variety of forms but is mainly driven by how the projects are
managed and how they
              are reported within the organization.
                If based on a known event, trend, demand, commitment or
uncertainty, future R&D
              expense or the mix of R&D expense is reasonably likely to differ
from current trends,
              please tell us the reasons for and the amount of the expected
change.
