          Securities Act of 1933, as amended (the &#8220;Securities Act&#8221;), and Section 21E of the Securities Exchange Act of 1934, as amended (the &#8220;Exchange Act&#8221;). Forward-looking statements include statements related to future events, results, performance,
          prospects and opportunities, including statements related to our strategic plans and targets, revenue generation, product availability and offerings, capital needs, capital expenditures, industry trends and our financial position. Forward-looking
          statements are based on information currently available to us, on our current expectations, estimates, forecasts, and projections about the industries in which we operate and on the beliefs and assumptions of management. Forward looking
          statements often contain words such as &#8220;expects,&#8221; &#8220;anticipates,&#8221; &#8220;could,&#8221; &#8220;targets,&#8221; &#8220;projects,&#8221; &#8220;intends,&#8221; &#8220;plans,&#8221; &#8220;believes,&#8221; &#8220;seeks,&#8221; &#8220;estimates,&#8221; &#8220;may,&#8221; &#8220;will,&#8221; &#8220;would,&#8221; and similar expressions. In addition, any statements that refer to
          projections of our future financial performance, our anticipated growth and trends in our business, and other characterizations of future events or circumstances, are forward-looking statements. Forward-looking statements by their nature address
          matters that are, to different degrees, subject to risks and uncertainties that could cause actual results to differ materially and adversely from those expressed in any forward-looking statements. For us, particular factors that might cause or
          contribute to such differences include those risks and uncertainties described in Part I, Item 1A &#8220;Risk Factors&#8221; of our Annual Report on Form 10-K for the year ended December 31, 2022 and described in other documents we file from time to time
          with the Securities and Exchange Commission, which we refer to as the SEC.</div>

              tested for impairment annually, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the entity is less than its carrying value. Because management evaluates
              the Company as a single reporting unit, goodwill is tested for impairment at the entity level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the entity is less than its
              carrying value. Such qualitative factors include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant events.&#160; If the entity does not pass the qualitative assessment,
              then the entity&#8217;s carrying value is compared to its fair value. Goodwill is considered impaired if the carrying value of the entity exceeds its fair value</span></span>.</div>

                                contract and civil conspiracy. Eterna acquired Novellus, Inc. on July 16, 2021.&#160; On May 27, 2022 Novellus, Inc. amended the complaint to withdraw all claims against all defendants except Paul Sowyrda and John Westman.&#160; On

          RSUs are settled in an equal number of shares of common stock on the vesting date of the award. An RSU award is settled only to the extent vested. Vesting generally requires the continued employment or service by the award recipient through the
          respective vesting date. Because RSUs are settled in an equal number of shares of common stock without any offsetting payment by the recipient, the measurement of cost is based on the quoted market price of the stock at the measurement date,
          which is the grant date.</div>

<div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt; text-indent: 36pt;">Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted
        net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding plus dilutive securities.&#160; Shares of common stock issuable upon exercise, conversion or vesting of stock options, RSUs, warrants and
        other convertible securities, including our outstanding Series A Convertible Preferred Stock, are considered potential common shares and are included in the calculation of diluted net loss per share using the treasury method when their effect is
        dilutive. Diluted net loss per share is the same as basic net loss per share for periods in which the effect of potentially dilutive shares of common stock is antidilutive. <ix:nonNumeric name="us-gaap:ScheduleOfAntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareTextBlock" id="Text_4146cb4ec2834f5ab02531f7d57c0c46" contextRef="c20230101to20230331" escape="true" continuedAt="Text_b1c7de4ebbb4433d89db5a0515db524f1"><span style="font-family: 'Times New Roman'; font-size: 10pt; color: #000000;">The following table presents the amount of warrants, stock options,

        <div style="text-align: justify; text-indent: 36pt;"> <br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">We are a life science company committed to realizing the potential of mRNA cell engineering to provide patients with transformational new medicines.&#160; We have in-licensed a portfolio of over 100
          patents covering key mRNA cell engineering technologies, including technologies for mRNA cell reprogramming, mRNA gene editing, the NoveSlice<sup style="vertical-align: text-top; line-height: 1; font-size: smaller;">TM</sup> and UltraSlice<sup style="vertical-align: text-top; line-height: 1; font-size: smaller;">TM</sup> gene-editing proteins, and the ToRNAdo<sup style="vertical-align: text-top; line-height: 1; font-size: smaller;">TM</sup> mRNA delivery system, which we collectively
          refer to as our &#8220;mRNA technology platform.&#8221; We plan to develop and advance a pipeline of therapeutic products, both internally and through strategic partnerships, with the near-term focus on deploying our mRNA technology platform through
          strategic partnerships.&#160; We license our mRNA technology platform from Factor Bioscience Limited (&#8220;Factor Limited&#8221;) under the Exclusive Factor License Agreement (as defined below).</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">Through strategic partnerships, we expect that our mRNA technology platform will be used for preclinical and eventual clinical development of product candidates for a variety of clinical
          indications. We expect that the initial product candidates developed by our strategic partners utilizing our mRNA technology platform will include hypoimmune induced pluripotent stem cell (&#8220;iPSC&#8221;)-derived product candidates for the treatment of
          neurological indications and iPSC-derived immune-modulating cells (&#8220;iIMCs&#8221;) for indications such as acute myeloid leukemia (&#8220;AML&#8221;) and solid tumors.</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">We refer to aspects of our mRNA technology platform as &#8220;mRNA delivery,&#8221; &#8220;mRNA gene editing&#8221; and &#8220;mRNA cell reprogramming.&#8221;</div>

        <div style="text-align: justify; font-style: italic;">mRNA Delivery</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">Nucleic acids, such as mRNA, can be used to induce cells to express desired proteins, including proteins that are capable of re-writing genetic and epigenetic cellular programs. However, the
          plasma membrane surrounding cells normally protects cells from exogenous nucleic acids, preventing efficient uptake and protein translation. Delivery systems can be used to enhance the uptake of nucleic acids by cells.&#160; Conventional delivery
          systems, such as lipid nanoparticle (&#8220;LNP&#8221;)-based delivery, often suffer from endosomal entrapment and toxicity, which can limit their therapeutic use.&#160; Our mRNA delivery technology is designed to use a novel chemical substance that is designed
          to deliver nucleic acids, including mRNA, to cells both <span style="font-style: italic;">ex vivo</span> and <span style="font-style: italic;">in vivo</span>. Our nucleic-acid delivery technology is also designed for <span style="font-style: italic;">ex vivo</span> delivery of mRNA encoding gene-editing proteins and reprogramming factors, including to primary cells, insertion of exogenous sequences into genomic safe-harbor loci, and <span style="font-style: italic;">in vivo</span>
          delivery of mRNA to the brain, eye, skin, and lung, which may be useful for the development of mRNA-based therapeutic.</div>

        <div style="text-align: justify; font-style: italic;">mRNA Gene Editing</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">Our mRNA gene-editing technology is designed to delete, insert, and repair DNA sequences in living cells, which may be useful for correcting disease-causing mutations, making cells resistant to
          infection and degenerative disease, modulating the expression of immunoregulatory proteins to enable the generation of durable allogeneic cell therapies, and engineering immune cells to more effectively fight cancer.</div>

          </div>

        </div>

        <div style="text-align: justify; text-indent: 36pt;">Conventional gene-editing technologies typically employ plasmids or viruses to express gene-editing proteins, which can result in low-efficiency editing and unwanted mutagenesis when an exogenous
          nucleic acid fragment is inserted at random locations in the genome. Our mRNA gene-editing technology instead is designed to employ mRNA to express gene-editing proteins, which can potentially enable gene editing without unwanted insertional
          mutagenesis, because, unlike conventional gene-editing technologies that employ viruses or DNA-based vectors, mRNA does not typically cause unwanted insertional mutagenesis. We believe the efficiency of our mRNA gene-editing technology has the
          potential to support development of product candidates that could create new therapeutic approaches. For example, we anticipate that our mRNA gene-editing technology can be used to generate allogeneic chimeric antigen receptor T-cell (&#8220;CAR-T&#8221;)
          therapies for the treatment of cancer. In such allogeneic CAR-T therapies, mRNA encoding gene-editing proteins would be used to inactivate the endogenous T-cell receptor to prevent therapeutic T-cells from causing graft-versus-host disease
          (&#8220;GvHD&#8221;). GvHD occurs when transplanted cells view the patient&#8217;s (i.e. the host&#8217;s) cells as a threat and attack the host&#8217;s cells. We expect that this same mechanism of action can generate allogeneic stem cell-derived therapies in which mRNA
          encoding gene-editing proteins could be used to inactivate one or more components of the human leukocyte antigen (&#8220;HLA&#8221;) complex to render the cells immuno-nonreactive or &#8220;stealth,&#8221; which may be useful for the development of allogeneic cell-based
          therapies.</div>

        <div style="text-align: justify; font-style: italic;">mRNA Cell Reprogramming</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">Our mRNA cell-reprogramming technology is capable of generating clonal lines of pluripotent stem cells that can be expanded and differentiated into many desired cell types that may be useful for
          the development of regenerative cell therapies.</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">Conventional cell-reprogramming technologies (e.g., using Sendai virus or episomal vectors) can result in low efficiency reprogramming, can select for cells with abnormal growth characteristics,
          and can leave traces of the vector in reprogrammed cells.<span style="font-weight: bold;">&#160;</span>Our mRNA cell-reprogramming technology instead is designed to employ mRNA to express reprogramming factors, which can enable cell reprogramming
          without leaving traces of the vector in reprogrammed cells, because, unlike conventional cell-reprogramming technologies that employ viruses or DNA-based vectors, mRNA does not typically leave traces of the vector in reprogrammed cells.</div>

          <div style="text-align: justify; text-indent: 24.5pt;">On February 20, 2023, we and Factor Limited entered into an exclusive license agreement (the &#8220;Exclusive Factor License Agreement&#8221;), which terminated and replaced in its entirety the Factor
            License Agreement, dated as of April 26, 2021, and amended on November 22, 2022, by and among us, Eterna Therapeutics LLC, Factor Limited and Novellus Therapeutics Limited.&#160; Subject to certain exclusive licenses or other rights granted by
            Factor Limited to certain third parties as of the effective date of the Exclusive Factor License Agreement, Factor granted us the exclusive, sublicensable license under certain patents owned by Factor Limited (the &#8220;Factor Patents&#8221;).</div>

          <div style="text-align: justify; text-indent: 24.5pt;">The term of the Exclusive Factor License Agreement expires on November 22, 2027, but will be automatically extended for an additional two and a half years (such period, the &#8220;Renewal Term&#8221;) if
            we receive at least $100 million in fees from sublicenses to the Factor Patents (&#8220;Sublicense Fees&#8221;) granted by us pursuant to the Exclusive Factor License Agreement.&#160; Pursuant to the Exclusive Factor License Agreement, we will pay to Factor
            Limited 20% of any Sublicense Fee received by us before the initial expiration date of such license and 30% of any Sublicense Fees received by us during the Renewal Term.&#160; We may terminate the Exclusive Factor License Agreement upon 120 days&#8217;

        </div>

        <div style="text-align: justify; text-indent: 36pt;">We are a pre-clinical stage company and have had no revenues from product sales to date. We will not have revenues from product sales until such time as we receive regulatory approval of our
          product candidates and successfully commercialize our products.&#160; During the quarter ended March 31, 2023, we entered into the Lineage Agreement, which is an agreement with a customer that includes an up-front option fee recognized as deferred
          revenue until the applicable performance obligation has been satisfied.&#160; This agreement could also include additional licensing and cell line customization revenues at Lineages&#8217;s discretion.&#160; There can be no assurances that we will recognize such

        <div style="text-align: justify; font-style: italic;">Research and Development Expenses</div>

        <div> <br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">We expense our research and development costs as incurred. Our research and development expenses consist of costs incurred for company-sponsored research and development activities, as well as
          support for selected investigator-sponsored research. Upfront payments and milestone payments we make for the in-licensing of technology are expensed as research and development in the period in which they are incurred if the technology is not
          expected to have any alternative future uses other than the specific research and development project for which it was intended. In-process research and development (&#8220;IPR&amp;D&#8221;) that we acquire and which has no alternative future uses and,
          therefore, no separate economic values, is expensed to research and development costs at the time the costs are incurred.</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt;">The major components of research and development costs have included preclinical study costs, clinical manufacturing costs, clinical study and trial expenses, insurance coverage for clinical
          trials, expensed licensed technology, consulting, scientific advisors and other third-party costs, salaries and employee benefits, stock-based compensation expense, supplies and materials and allocations of various overhead costs related to our
          product development efforts.</div>

        <div><br />
        </div>

        <div style="text-align: justify; text-indent: 36pt; margin-right: 0.1pt; margin-left: 0.1pt;">We have contracted with third parties to perform various clinical study and trial activities in the development and testing of potential products. The
          financial terms of these agreements vary from contract to contract and may result in uneven payment flows. We accrue for third party expenses based on estimates of the services received and efforts expended during the reporting period.&#160; If the
          actual timing of the performance of the services or the level of effort varies from the estimate, the accrual is adjusted accordingly.&#160; The expenses for some third-party services may be recognized on a straight-line basis if the expected costs
          are expected to be incurred ratably during the period. Payments under the contracts depend on factors such as the achievement of certain events or milestones, the successful enrollment of patients, the allocation of responsibilities among the
          parties to the agreement, and the completion of portions of the clinical study or trial or similar conditions. Preclinical and clinical study and trial associated activities such as production and testing of clinical material require significant
          up-front expenditures.</div>

        <div style="text-align: justify; text-indent: 36pt;">Our general and administrative expenses decreased for the three months ended March 31, 2023 primarily due to decreases in payroll expenses and stock-based compensation expense resulting from
          lower headcount, occupancy expense due to having fewer leased offices, as well as professional fees and other miscellaneous expenses when compared to the three months ended March 31, 2022.</div>

        <div style="text-align: justify; text-indent: 36pt;">For the three months ended March 31, 2023, we recognized an increase in the change in the fair value of warrant liabilities due to an increase in the market price of our common stock as of March
          31, 2023.&#160; The $1.3 million of warrant liabilities expense recognized for the three months ended March 31, 2022 included (i) $0.6 million related to the excess fair value of the Common Warrants and Pre-Funded Warrant (each as defined in <span style="color: #000000;">Note 4 to the unaudited condensed consolidated financial statements contained in this Quarterly Report on Form 10-Q)</span> issued in connection with the March 2022 private placement over the $12.0 million gross proceeds

          of credit was issued <a id="z_Hlk118111664"></a>by our commercial bank, which required that we cash collateralize the letter of credit with $4.1 million of cash deposited in a restricted account maintained by such bank.&#160; The amount of required

          satisfy our need for working capital.&#160; While we are not presently pursuing product development, we may do so in the future, and current and potential licensing partners may seek to do so.&#160; Developing product candidates, conducting clinical trials
          and commercializing products are expensive, and we would need to raise substantial additional funds if we were to pursue the development of one or more product candidates Based on our current financial condition and forecasts of available cash,
          we believe we do not have sufficient funds to fund our operations for the next twelve months from the filing of the financial statements contained in this Quarterly Report on Form 10-Q for the three months ended March 31, 2023. We can provide no
          assurance that we will be able to satisfy our near- or long-term cash needs through licensing transactions, or that we will obtain any additional financing that we require in the future or, even if such financing is available, that it will be

          our reports filed pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC&#8217;s rules and forms, and that such information is accumulated and communicated to our management, including

        <div style="text-align: justify; text-indent: 36pt;">In designing and evaluating the disclosure controls and procedures, we recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance
          of achieving the desired control objectives, and we were required to apply our judgment in evaluating the cost-benefit relationship of possible controls and procedures. We have carried out an evaluation as of the end of the period covered by this
          Quarterly Report on Form 10-Q under the supervision, and with the participation, of our management, including our Chief Executive Officer and President (who serves as our principal executive officer) and our Chief Financial Officer (who served as
          our principal financial officer through the end of the three month period ended March 31, 2023 and resigned from the Company effective May 4, 2023), of the effectiveness of the design and operation of our disclosure controls and procedures.</div>

        <div style="text-align: justify; text-indent: 36pt;">Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed to provide

        <div style="text-align: justify; text-indent: 36pt;">We were unable to timely file our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022 with the SEC due to identifying errors in our financial statements reported in the
          Annual Report on Form 10-K for the years ended December 31, 2021 and 2020 during our preparation of the financial statements for the quarter ended March 31, 2022. Management concluded that the errors were the result of accounting personnel&#8217;s lack
          of technical proficiency in complex matters. We filed an amendment to our Annual Report on Form 10-K/A for the years ended December 31, 2021 and 2020 on June 30, 2022 to correct the errors in our financial statements for the years ended December
          31, 2021 and 2020 and for the quarters ended June 30, 2020, September 30, 2020, March 31, 2021, June 30, 2021 and September 30, 2021.</div>

      <div style="text-align: justify;">I, Matthew Angel, certify that:</div>
      <div>&#160;<br>
      </div>
      <div>1. I have reviewed this Quarterly Report on Form 10-Q of Eterna Therapeutics Inc.</div>
      <div>&#160;<br>
      </div>
      <div>2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not
        misleading with respect to the period covered by this report.</div>
      <div>&#160;<br>

        the periods presented in this report.</div>
      <div>&#160;<br>

      <div>4. The registrant&#8217;s other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
        defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:</div>
      <div>&#160;<br>

      <div>(a) designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated
        subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is being prepared;</div>
      <div>&#160;<br>
      </div>
      <div>(b) designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the
        preparation of financial statements for external purposes in accordance with generally accepted accounting principles;</div>
      <div>&#160;<br>
      </div>
      <div>(c) evaluated the effectiveness of the registrant&#8217;s disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures, as of the end of the period covered by this
        report based on such evaluation; and</div>
      <div>&#160;<br>
      </div>
      <div>(d) disclosed in this report any change in the registrant&#8217;s internal control over financial reporting that occurred during the registrant&#8217;s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect,
        the registrant&#8217;s internal control over financial reporting.</div>

      <div>&#160;<br>
      </div>
      <div>(a) all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant&#8217;s ability to record, process, summarize and report
        financial information; and</div>
      <div>&#160;<br>
      </div>

                substantial doubt regarding the Company&#8217;s ability to continue as a going concern because it does not expect to have sufficient cash or working capital resources to fund operations for the twelve-month period subsequent to the issuance date
                of these financial statements. The Company will need to raise additional capital, which could be through public or private equity offerings, debt financings, strategic partnerships or other means. Other than the two-year purchase agreement with the investment group discussed above, the Company currently has no arrangements for such capital, and no
                assurances can be given that it will be able to raise such capital when needed, on acceptable terms, or at all.</div>

        customer may request in the future and will be accounted for as separate contracts when the customer exercises the Option Right or provides its request to the Company to perform the cell line customization activities.&#160; As a result, the Option Right
        performance obligation is the only performance obligation as of contract inceptions, and 100% of the Option Fee is allocated to the
        Option Right.&#160; Revenue from the Option Right will be recognized when the customer enters into the sublicense or when the Option Right expires.&#160; As of March 31, 2023, the Company has recorded $250,000 as deferred revenue related to the upfront, nonrefundable Option Fee.</div>

              willing market participants. A fair value hierarchy has been established for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable
              inputs. The fair value hierarchy is as follows:</div>

              research and development efforts in Cambridge, Massachusetts, and the Company determined to sublease the San Diego laboratory and office space.&#160; On January 31, 2023, the Company terminated its lease in San Diego, California pursuant to a
              lease termination agreement entered into with the lessor in November 2022 and amended in December 2022.&#160; The Company paid a $0.1
              million lease termination fee in January 2023.&#160; The lease termination was accounted for as a modification because the Company did not contemporaneously terminate the lease when it entered into the lease termination agreement on November 30,
              2022 (the &#8220;Modification Date&#8221;) and had a continued right-of-use of the facility through January 31, 2023.&#160; As a result, on the Modification Date, the Company remeasured the remaining lease payments, including the $0.1 million termination fee, and reduced the lease liability the Company had on its balance sheet on the Modification Date by approximately $1.4 million to the present value of the remeasured lease liability of approximately $0.2 million and reduced the ROU asset by approximately $0.8 million to zero.&#160; As of March 31, 2023, the Company had no
              remaining lease liabilities associated with this lease.</div>

              (such applicable date, the &#8220;Rent Commencement Date&#8221;). The Sublease has a term of 10 years from the Rent Commencement Date (the

              default by the Company under the Sublease, the letter of credit will be reduced on an incremental basis throughout the Term. Pursuant to the Sublease, the Company has agreed to pay base rent of approximately $0.5 million per month during the first year of the Term, increasing on an incremental basis each subsequent year of the Term for a total of
              approximately $63.0 million in base rental payments, as well as parking and traditional lease expenses, including certain taxes,

              tenant improvement allowance of $190 per rentable square foot, or $8.6 million.&#160; Tenant improvements to the Premises in excess of this amount, if any, will be at the Company&#8217;s own cost. As of March 31, 2023, the Premises had not been made available
              for the Company to begin the construction of the tenant improvements.&#160; It is expected that the Premises will be made available to begin the construction during the second quarter of 2023, and it is anticipated that the construction will be
              substantially complete during the fourth quarter of 2023.&#160; As a result, the commencement date of the Sublease did not occur as of March 31, 2023, and accordingly, the Company did not recognize a lease liability and corresponding ROU asset for
              the Sublease as of March 31, 2023.</div>

              tested for impairment annually, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the entity is less than its carrying value. Because management evaluates
              the Company as a single reporting unit, goodwill is tested for impairment at the entity level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the entity is less than its
              carrying value. Such qualitative factors include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant events.&#160; If the entity does not pass the qualitative assessment,
              then the entity&#8217;s carrying value is compared to its fair value. Goodwill is considered impaired if the carrying value of the entity exceeds its fair value</span></span>.</div>

                                consolidate the Delaware Actions with this action.&#160; On December 15, 2022, Sowyrda filed an Amended Answer to the Amended Complaint, asserted affirmative defenses and filed Amended Counterclaims against Dr. Angel, Dr. Rohde,
                                Novellus LLC, Novellus Inc., Factor Bioscience Inc., and Eterna Therapeutics Inc. (&#8220;Counterclaim Defendants&#8221;) alleging against various Counterclaim Defendants breach of contract, breaches of the implied duty of good faith
                                and fair dealing, breaches of fiduciary duty, breaches of the operating agreement, aiding and abetting breaches of fiduciary duty, tortious interference with contract, equitable accounting, violations of the Massachusetts

                                counterclaims against the same Counterclaim Defendants.&#160; Westman and Sowyrda each asserted claims for indemnification and/or advancement against Novellus, Inc.&#160; On January 11, 2023, Westman and Sowyrda served a joint motion
                                to enforce their advancement and/or indemnification rights against Novellus Inc.&#160; Novellus Inc. vigorously opposes this motion and served its opposition on January 27, 2023.&#160; On February 8, 2023, Westman and Sowyrda served a
                                reply in support of their motion to enforce indemnification/advancement rights, and submitted the motion to the Court.&#160; Novellus Inc. answered Westman and Sowyrda&#8217;s counterclaims on January 27, 2023, denying liability.&#160; The
                                remaining Counterclaim Defendants served a motion to dismiss most of the remaining counterclaims on January 27, 2023.&#160; The motion to dismiss is now fully briefed, and the Court has scheduled oral argument for May 23, 2023 on
                                (a) the Counterclaim Defendants&#8217; motion to dismiss, and (b) Sowyrda&#8217;s and Westman&#8217;s motion to enforce. <br/>

          RSUs are settled in an equal number of shares of common stock on the vesting date of the award. An RSU award is settled only to the extent vested. Vesting generally requires the continued employment or service by the award recipient through the
          respective vesting date. Because RSUs are settled in an equal number of shares of common stock without any offsetting payment by the recipient, the measurement of cost is based on the quoted market price of the stock at the measurement date,
          which is the grant date.</div>

              settlement provision that does not meet the requirements of the indexation guidance under ASC 815-40.&#160; These warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within the
              statement of operations.&#160; (See Note 4 for more information related to changes in fair value.) Upon exercise of the Common Warrants and Pre-Funded Warrants, the fair value on the exercise date is reclassified from warrant liabilities to

<div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt; text-indent: 36pt;">Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted
        net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding plus dilutive securities.&#160; Shares of common stock issuable upon exercise, conversion or vesting of stock options, RSUs, warrants and
        other convertible securities, including our outstanding Series A Convertible Preferred Stock, are considered potential common shares and are included in the calculation of diluted net loss per share using the treasury method when their effect is
        dilutive. Diluted net loss per share is the same as basic net loss per share for periods in which the effect of potentially dilutive shares of common stock is antidilutive. <span style="font-family: 'Times New Roman'; font-size: 10pt; color: #000000;">The following table presents the amount of warrants, stock options,
        convertible preferred stock and RSUs that were excluded from the computation of diluted net loss per common share for the three months ended March 31, 2023 and 2022, as their effect was anti-dilutive (in thousands):</span></div>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

                substantial doubt regarding the Company&#x2019;s ability to continue as a going concern because it does not expect to have sufficient cash or working capital resources to fund operations for the twelve-month period subsequent to the issuance date
                of these financial statements. The Company will need to raise additional capital, which could be through public or private equity offerings, debt financings, strategic partnerships or other means. Other than the two-year purchase agreement with the investment group discussed above, the Company currently has no arrangements for such capital, and no
                assurances can be given that it will be able to raise such capital when needed, on acceptable terms, or at all.&lt;/div&gt;

        material right because by entering into the agreement, the Option Right allows the customer to obtain a license that no other customer can receive.&#160; As a result, the Option Right is a separate performance obligation under the agreement.&#160; The cell
        line customization activities that the Company may perform and the granting of the license that the Company may provide to the customer are not considered performance obligations as of contract inception, as these are goods and services that the
        customer may request in the future and will be accounted for as separate contracts when the customer exercises the Option Right or provides its request to the Company to perform the cell line customization activities.&#160; As a result, the Option Right
        performance obligation is the only performance obligation as of contract inceptions, and 100% of the Option Fee is allocated to the
        Option Right.&#160; Revenue from the Option Right will be recognized when the customer enters into the sublicense or when the Option Right expires.&#160; As of March 31, 2023, the Company has recorded $250,000 as deferred revenue related to the upfront, nonrefundable Option Fee.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman'; font-size: 10pt;"&gt;Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between
              willing market participants. A fair value hierarchy has been established for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable
              inputs. The fair value hierarchy is as follows:&lt;/div&gt;

              research and development efforts in Cambridge, Massachusetts, and the Company determined to sublease the San Diego laboratory and office space.&#160; On January 31, 2023, the Company terminated its lease in San Diego, California pursuant to a
              lease termination agreement entered into with the lessor in November 2022 and amended in December 2022.&#160; The Company paid a $0.1
              million lease termination fee in January 2023.&#160; The lease termination was accounted for as a modification because the Company did not contemporaneously terminate the lease when it entered into the lease termination agreement on November 30,
              2022 (the &#x201c;Modification Date&#x201d;) and had a continued right-of-use of the facility through January 31, 2023.&#160; As a result, on the Modification Date, the Company remeasured the remaining lease payments, including the $0.1 million termination fee, and reduced the lease liability the Company had on its balance sheet on the Modification Date by approximately $1.4 million to the present value of the remeasured lease liability of approximately $0.2 million and reduced the ROU asset by approximately $0.8 million to zero.&#160; As of March 31, 2023, the Company had no
              remaining lease liabilities associated with this lease.&lt;/div&gt;

              (such applicable date, the &#x201c;Rent Commencement Date&#x201d;). The Sublease has a term of 10 years from the Rent Commencement Date (the

              security deposit in the form of a letter of credit in the amount of approximately $4.1 million. Provided there are no events of
              default by the Company under the Sublease, the letter of credit will be reduced on an incremental basis throughout the Term. Pursuant to the Sublease, the Company has agreed to pay base rent of approximately $0.5 million per month during the first year of the Term, increasing on an incremental basis each subsequent year of the Term for a total of
              approximately $63.0 million in base rental payments, as well as parking and traditional lease expenses, including certain taxes,

              tenant improvement allowance of $190 per rentable square foot, or $8.6 million.&#160; Tenant improvements to the Premises in excess of this amount, if any, will be at the Company&#x2019;s own cost. As of March 31, 2023, the Premises had not been made available
              for the Company to begin the construction of the tenant improvements.&#160; It is expected that the Premises will be made available to begin the construction during the second quarter of 2023, and it is anticipated that the construction will be
              substantially complete during the fourth quarter of 2023.&#160; As a result, the commencement date of the Sublease did not occur as of March 31, 2023, and accordingly, the Company did not recognize a lease liability and corresponding ROU asset for
              the Sublease as of March 31, 2023.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman'; font-size: 10pt;"&gt;In 2018, the Company acquired IRX Therapeutics (&#x201c;IRX&#x201d;), which was accounted for as a business combination. The Company recorded goodwill in the

              tested for impairment annually, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the entity is less than its carrying value. Because management evaluates
              the Company as a single reporting unit, goodwill is tested for impairment at the entity level by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the entity is less than its
              carrying value. Such qualitative factors include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant events.&#160; If the entity does not pass the qualitative assessment,
              then the entity&#x2019;s carrying value is compared to its fair value. Goodwill is considered impaired if the carrying value of the entity exceeds its fair value&lt;/span&gt;&lt;/span&gt;.&lt;/div&gt;

          2022 (the &#x201c;Original Factor License Agreement&#x201d;).&#160; Under the terms of the Waiver Agreement, the License Fee Obligation is waived conditionally on the Company paying Factor Bioscience amounts due under the MSA&lt;span style="color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; text-align: justify; text-indent: 48px; text-transform: none; white-space: normal; word-spacing: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: inline ! important; float: none;"&gt;.&lt;/span&gt;&lt;/div&gt;

              Factor Limited entered into an exclusive license agreement (the &#x201c;Exclusive Factor License Agreement&#x201d;) , which terminated and superseded the Original Factor License Agreement.&#160; Subject to certain exclusive licenses or other rights granted by
              Factor Limited to other third parties as of the effective date of the Exclusive Factor License Agreement, Factor granted the Company the exclusive, sublicensable license under certain patents owned by Factor Limited (the &#x201c;Factor Patents&#x201d;).
              The term of the Exclusive Factor License Agreement expires on November 22, 2027, but will be automatically extended for an additional &lt;span style="-sec-ix-hidden:Fact_a1b4ba1f78d045bc91d9dac595201682"&gt;two and a half years&lt;/span&gt; (such period, the &#x201c;Renewal Term&#x201d;) if the Company receives at least $100 million in fees from sublicenses
              to the Factor Patents (&#x201c;Sublicense Fees&#x201d;) granted by the Company pursuant to the Exclusive Factor License Agreement.&#160; The Company will pay to Factor Limited 20% of any Sublicense Fee received by the Company before the initial expiration date of such license and 30%
              of any Sublicense Fees received by the Company during the Renewal Term.&#160; The Company may terminate the Exclusive Factor License Agreement upon 120
              days&#x2019; written notice to Factor Limited, and both parties otherwise have additional customary termination rights.&#160; Under the Exclusive Factor License Agreement, the Company is obligated to pay the expenses incurred by Factor Limited in
              preparing, filing, prosecuting and maintaining the Factor Patents and has agreed to bear all costs and expenses associated with enforcing and defending the Factor Patents in any action or proceeding arising from pursuit of sublicensing
              opportunities under the license granted under the Exclusive Factor License Agreement.&lt;/span&gt;&lt;br/&gt;

            September 2022, Novellus and Eterna entered into a Second Amendment to the Limited Waiver and Assignment Agreement (the &#x201c;Waiver and Assignment Agreement&#x201d;) with Drs. Matthew Angel and Christopher Rohde (the &#x201c;Founders&#x201d;) whereby the Company has
            agreed to be responsible for all future, reasonable and substantiated legal fees, costs, settlements and judgments incurred by the Founders, the Company or Novellus for certain claims and actions and any pending or future litigation brought
            against the Founders, Novellus and/or the Company by or on behalf of the Westman and Sowyrda legal matters described in Note 9 (the &#x201c;Covered Claims&#x201d;).&#160; The Founders will continue to be solely responsible for any payments made to satisfy a
            judgement or settlement of any pending or future wage act claims.&#160; Under the Waiver and Assignment Agreement, the Founders agreed that they are not entitled to, and waived any right to, indemnification or advancement of past, present or future
            legal fees, costs, judgments, settlement or other liabilities they may have been entitled to receive from the Company or Novellus in respect of the Covered Claims. The Company and the Founders will share in any recoveries up to the point at
            which the parties have been fully compensated for legal fees, costs and expenses incurred, with the Company retaining any excess recoveries. The Company has the sole authority to direct and control the prosecution, defense and settlement of the
            Covered Claims.&lt;/div&gt;

                                employees Paul Sowyrda and John Westman and certain other former investors in Novellus LLC (Novellus, Inc.&#x2019;s former parent company prior to our acquisition of Novellus, Inc.), alleging breach of fiduciary duty, breach of
                                contract and civil conspiracy. Eterna acquired Novellus, Inc. on July 16, 2021.&#160; On May 27, 2022 Novellus, Inc. amended the complaint to withdraw all claims against all defendants except Paul Sowyrda and John Westman.&#160; On
                                July 1, 2022, Westman filed a motion to compel arbitration or in the alternative, to stay the litigation pending the disposition of certain litigation in the Court of Chancery for the State of Delaware filed by Mr. Sowyrda

                                counterclaims against the same Counterclaim Defendants.&#160; Westman and Sowyrda each asserted claims for indemnification and/or advancement against Novellus, Inc.&#160; On January 11, 2023, Westman and Sowyrda served a joint motion
                                to enforce their advancement and/or indemnification rights against Novellus Inc.&#160; Novellus Inc. vigorously opposes this motion and served its opposition on January 27, 2023.&#160; On February 8, 2023, Westman and Sowyrda served a
                                reply in support of their motion to enforce indemnification/advancement rights, and submitted the motion to the Court.&#160; Novellus Inc. answered Westman and Sowyrda&#x2019;s counterclaims on January 27, 2023, denying liability.&#160; The
                                remaining Counterclaim Defendants served a motion to dismiss most of the remaining counterclaims on January 27, 2023.&#160; The motion to dismiss is now fully briefed, and the Court has scheduled oral argument for May 23, 2023 on
                                (a) the Counterclaim Defendants&#x2019; motion to dismiss, and (b) Sowyrda&#x2019;s and Westman&#x2019;s motion to enforce. &lt;br/&gt;

          RSUs are settled in an equal number of shares of common stock on the vesting date of the award. An RSU award is settled only to the extent vested. Vesting generally requires the continued employment or service by the award recipient through the
          respective vesting date. Because RSUs are settled in an equal number of shares of common stock without any offsetting payment by the recipient, the measurement of cost is based on the quoted market price of the stock at the measurement date,
          which is the grant date.&lt;/div&gt;

              statement of operations.&#160; (See Note 4 for more information related to changes in fair value.) Upon exercise of the Common Warrants and Pre-Funded Warrants, the fair value on the exercise date is reclassified from warrant liabilities to

&lt;div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt; text-indent: 36pt;"&gt;Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted
        net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding plus dilutive securities.&#160; Shares of common stock issuable upon exercise, conversion or vesting of stock options, RSUs, warrants and
        other convertible securities, including our outstanding Series A Convertible Preferred Stock, are considered potential common shares and are included in the calculation of diluted net loss per share using the treasury method when their effect is
        dilutive. Diluted net loss per share is the same as basic net loss per share for periods in which the effect of potentially dilutive shares of common stock is antidilutive. &lt;span style="font-family: 'Times New Roman'; font-size: 10pt; color: #000000;"&gt;The following table presents the amount of warrants, stock options,
        convertible preferred stock and RSUs that were excluded from the computation of diluted net loss per common share for the three months ended March 31, 2023 and 2022, as their effect was anti-dilutive (in thousands):&lt;/span&gt;&lt;/div&gt;
