Overview

Standard BioTools Inc. is driven by a bold purpose - unleashing tools to
accelerate breakthroughs in human health. We have an established portfolio of
essential, standardized next-generation high resolution technologies that help
biomedical researchers develop medicines faster and better. Our tools are
designed to provide reliable and repeatable insights in health and disease using
our proprietary mass cytometry and microfluidics technologies, which serve
applications in proteomics and genomics that help transform scientific
discoveries into better patient outcomes. We work with leading academic,
government, pharmaceutical, biotechnology, plant and animal research, and
clinical laboratories worldwide, focusing on the most pressing needs in
translational and clinical research, including oncology, immunology, and
immunotherapy.

We distribute our systems through our direct sales force and support
organizations located in North America, Europe, and Asia-Pacific, and through
distributors or sales agents in several European, Latin American, Middle
Eastern, and Asia-Pacific countries. Our manufacturing operations are located in
Singapore and Canada.

Our total revenue was $97.9 million in 2022 compared to $130.6 million in 2021. We have incurred significant net losses since our inception in 1999 and our accumulated deficit was $926.1 million as of December 31, 2022.

Critical Accounting Estimates



The consolidated financial statements and related notes included in this Form
10-K are prepared in accordance with generally accepted accounting principles in
the United States (U.S. GAAP). Preparing U.S. GAAP financial statements requires
the use of estimates and assumptions to determine the value of the assets,
liabilities, revenues and expenses reported on the consolidated balance sheets
and statements of operations. We develop these estimates after considering
historical transactions, the current economic environment and various other
assumptions considered reasonable under the circumstances. Actual results may
differ materially from these estimates and judgments. Accounts that rely heavily
on estimated information to determine their values include revenue, trade
receivables, inventories, right-of-use assets, goodwill, long-lived intangible
assets, lease liabilities, and preferred equity. Refer to Note 2 to our
consolidated financial statements for further information on our most
significant accounting policies.

Revenue



We recognize revenue based on the amount of consideration we expect to receive
in exchange for the goods and services we transfer to the customer. Our
commercial arrangements typically include multiple, distinct products and
services, and we allocate purchase consideration to the products and services
based on each item's relative standalone selling price. Standalone selling
prices (SSP) are generally determined using observable data from recent
transactions. In cases where sufficient data is not available, we estimate a
product's SSP using a cost plus margin approach or by applying a discount to the
product's list price.

We have entered and may continue to enter into development agreements with
customers that require us to recognize revenue using an input method that
determines the extent of our progress toward completion by comparing the actual
costs incurred to the total expected cost. As part of the accounting for these
arrangements, we develop estimates and assumptions that require judgment to
determine the transaction price and progress towards completion. We review these
estimates at the end of each reporting period using the best available
information, revise the estimates as necessary, and recognize revenue
commensurate with our progress toward completion.

Trade Receivables

Trade accounts receivable are recorded at net invoice value. We review our exposure to accounts receivable and provide allowances for uncollectible specific amounts if collectability is no longer reasonably assured. We evaluate such allowances on a regular basis and adjust them as needed. Significant judgment is required in determining the amounts of any such allowances.

Inventories



Inventories are stated at the lower of cost (on a first-in, first-out basis) or
net realizable value. Inventory costs include direct materials, direct labor,
and normal manufacturing overhead. We regularly review inventory for excess and
obsolete products and components. Significant judgment is required in
determining provisions for slow-moving, excess, and obsolete inventories which
are recorded when required to reduce inventory values to their estimated net
realizable values based on product life cycle, development plans, product
expiration, and quality issues.

Right-of-Use Assets and Lease Liabilities



We determine if an arrangement is a lease, or contains a lease, at inception.
Operating leases are included in operating lease right-of-use (ROU) assets, and
operating lease liabilities in our consolidated balance sheets. ROU assets
represent our right to use an underlying asset for the lease term and lease
liabilities represent our obligation to make lease payments arising from the

                                       48

--------------------------------------------------------------------------------

lease. Operating lease ROU assets and liabilities are recognized at the
commencement date of the lease based on the present value of lease payments over
the lease term. As most of our leases do not provide an implicit rate, we
generally use our incremental borrowing rate based on the estimated rate of
interest for collateralized borrowing over a similar term of the lease payments
at commencement date. Significant judgment is required in determining the
incremental collateralized borrowing rate. Lease expense for lease payments is
recognized on a straight-line basis over the lease term.

Goodwill and Long-Lived Assets



Assessing goodwill and long-lived assets for impairment requires significant
judgment as it involves selecting an appropriate valuation method, identifying
reporting units, assigning assets and liabilities to the reporting units, and
estimating future cash flows, remaining service lives, revenue growth rates,
terminal values and discount rates.

Series B Redeemable Preferred Stock



The Purchase Agreements (as defined in Note 3 to the consolidated financial
statements) for the issuance of shares of Series B Preferred Stock were
accounted for as forward sales contracts at fair value in accordance with ASC
480, Distinguishing Liabilities from Equities. The Series B Preferred Stock was
treated as mezzanine equity and recorded at its fair value upon issuance, net of
issuance costs due to its redemption features, such as change of control and
liquidation preference, which are outside of the Company's control. Subsequent
remeasurement of the Series B Redeemable Preferred Stock amount presented within
mezzanine equity to its redemption amount is not required since it is not
probable that the instrument will become redeemable. Mezzanine equity which has
characteristics of both liabilities and shareholders' equity (deficit) is
presented separately on the consolidated balance sheets between these two items
because it has some characteristics of both. Refer to Note 3 to the consolidated
financial statements for additional information.

Recent Accounting Changes and Accounting Pronouncements

Adoption of New Accounting Guidance



In August 2020, the Financial Accounting Standards Board (FASB) issued
Accounting Standards Update (ASU) 2020-06 Debt-Debt with Conversion and Other
Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own
Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts
in an Entity's Own Equity. The amendment to this ASU reduces the number of
accounting models for convertible instruments and allows more contracts to
qualify for equity classification, which is expected to result in more
convertible instruments being accounted for as a single unit, rather than being
bifurcated between debt and equity. The new guidance was effective for fiscal
years beginning after December 15, 2021. We adopted ASU 2020-06 effective
January 1, 2022. The adoption of ASU 2020-06 did not have an impact on our
financial results.

In November 2021, the FASB issued ASU 2021-10 Government Assistance (Topic 832):
Disclosures by Business Entities about Government Assistance. The amendment was
effective for annual periods beginning after December 15, 2021. The amendment
established financial disclosure requirements for business entities that receive
government assistance they account for by analogizing to a grant or contribution
model due to a lack of specific GAAP guidance for such transactions. Entities
that receive this type of assistance are required to include the following
information in the notes to their financial statements: (1) the nature of the
transaction, (2) the significant terms and conditions, (3) the accounting
treatment, (4) the line items on the balance sheet and income statement that are
affected along with (5) the respective amounts that have been recorded. We
adopted ASU 2021-10 effective January 1, 2022.

Recent Accounting Pronouncements

None.

Revenue



We generate revenue primarily from sales of our products and services. Our
product revenue consists of sales of instruments and consumables. Consumables
revenue is largely driven by the size of our active installed base and the level
of usage per instrument. Service revenue is also linked to the size of our
active installed base as it is primarily comprised of post-warranty service
contracts for instruments.

Revenue by product type and as a percentage of total revenue are as follows ($

Americas revenue includes United States revenue of $41.0 million and $60.2 million for the years ended December 31, 2022, and 2021, respectively. Asia-Pacific includes revenue generated in China of $11.3 million and $12.5 million for 2022 and 2021, respectively. With the exception of China, no foreign country had revenue that exceeded of 10% of total revenues in 2022 or 2021.

One genomics customer accounted for 11% of total revenue for the year ended December 31, 2022. No customer represented more than 10% of total revenue for the year ended December 31, 2021.

Revenue from our five largest customers represented 19% of total revenues for the year ended December 31, 2022 and 23% for the year ended December 31, 2021.



Total Revenue. Total revenue decreased by $32.6 million, or 25%, for the year
ended December 31, 2022, compared to the year ended December 31, 2021, driven
primarily by a $27.9 million, or 28%, decline in product revenue and a $2.2
million, or 9%, decline in service revenue. A stronger U.S. dollar negatively
impacted the Company's total revenue by $3.6 million, or 2.8 percent.

Americas revenue declined by $19.9 million, or 31%, for the year ended
December 31, 2022, compared to the year ended December 31, 2021, primarily due
to a reduction in product revenue from discontinued product lines, including our
COVID-19 test products, and from lower unit sales of proteomics instruments.
EMEA revenue decreased by $9.6 million, or 22%, primarily driven by a decline in
proteomics instrument revenue. A stronger U.S. dollar negatively impacted EMEA
revenue by approximately 4.7 percent. In Asia-Pacific, revenue decreased by
$3.2 million, or 13%, primarily due to a decline in proteomics revenue. A
stronger U.S. dollar negatively impacted Asia-Pacific revenues by approximately
5.8 percent.

Proteomics. Proteomics product and service revenue declined by $16.0 million, or
24%, for the year ended December 31, 2022, compared to the year ended
December 31, 2021. The year-over-year decline is primarily attributable to lower
unit sales of instruments.

Genomics. Genomics product and service revenue declined by $14.1 million, or
24%, during the year ended December 31, 2022 compared to the year ended
December 31, 2021. The year-over-year decline is primarily attributable to the
reduced demand for COVID-19 test kits and other products that were discontinued
in 2022. An increase in OEM revenue was offset by a decline in sales to other
customers.

We expect the average selling prices of our products to fluctuate over time based on market conditions, product mix, and currency fluctuations.

Product and Service Cost, Product and Service Gross Profit, and Product and Service Margin



Cost of product revenue includes manufacturing costs incurred in the production
process, including component materials, labor and overhead, installation,
packaging, and delivery costs. In addition, cost of product revenue includes
amortization of developed technology and intangibles, royalty costs for licensed
technologies included in our products, warranty, provisions for slow-moving and
obsolete inventory, and stock-based compensation expense. Our cost of product
revenue and related product margin may fluctuate depending on the capacity
utilization of our manufacturing facilities in response to market conditions and
the demand for our products.

Cost of service revenue includes direct labor hours, overhead, and instrument parts. Our cost of service revenue and related service margin may fluctuate depending on the variability in material and labor costs of servicing instruments.

Product and service margin decreased by 14.8 percentage points for the year
ended December 31, 2022 compared to the year ended December 31, 2021. Increased
provisions for excess and obsolete inventory accounted for 6.4 percentage points
of the decline in the product and service margin. Provisions for excess and
obsolete inventory were $7.9 million, or 8.2%, of product and service revenue
for the twelve months ended December 31, 2022 compared to $2.3 million, or 1.8%,
of product and service revenue for the twelve months ended December 31, 2021.
The increase in these provisions primarily reflects the impact of our portfolio
rationalization initiatives. Fixed depreciation and amortization costs on a
lower revenue base contributed 2.9 percentage points to the decline in product
and service margin, while other factors, including an unfavorable product mix
and higher service costs contributed 2.9 and 2.4 percentage points,
respectively.

Research and Development

Research and development expense consists primarily of compensation-related
costs, product development and material expenses, and other allocated facilities
and information technology expenses. Our research and development efforts have
focused primarily on enhancing our technologies and supporting the development
and commercialization of new and existing products and services. Research and
development expense also includes costs incurred in conjunction with research
grants and development arrangements.

Research and development expense increased by $0.6 million, or 1%, to $38.5
million in 2022 compared to $37.9 million in 2021. The increase is primarily
attributable to a $3.5 million non-cash impairment charge to write off
long-lived intangible assets associated with discontinued products and $1.1
million of restructuring expenses. These expenses were mostly offset by a $2.3
million reduction in laboratory supplies, a $1.4 million reduction in consulting
fees, and a $0.4 million reduction in stock-based compensation expense, each of
which reflect reduced and refocused program activity.

Selling, General and Administrative

Selling, general and administrative (SG&A) expense consists primarily of personnel costs for, sales, marketing, business development, finance, legal, human resources, information technology, and general management, as well as professional services, including legal and accounting.



SG&A expense increased by $15.9 million, or 16%, to $114.8 million in 2022
compared to $98.9 million in 2021. The strategic financing and business
improvement initiatives launched in 2022 increased SG&A expenses by $17.2
million. The total includes $4.2 million of restructuring and other related
costs involving former executives, $3.8 million for retention bonuses to retain
key employees, $3.8 million for legal and consulting fees in support of the
private placement issuance, Company name change, and rebranding activities, $2.7
million for severance, $2.2 million in business improvement initiatives for
strategic advisory and business consulting expenses, and $0.4 million to upgrade
the ERP system. There was also a $2.0 million increase in travel expenses, as
COVID-19 travel-related restrictions were relaxed. These cost increases were
partially offset by a $1.7 million decrease in compensation expense and a $0.8
million decrease in stock-based compensation expense

Proteomics. Proteomics loss from operations increased by $17.8 million, or 163%,
for the year ended December 31, 2022 compared to the year ended December 31,
2021. The year over year increase in operating loss was primarily attributable
to an $11.8 million reduction in gross profit driven by lower unit sales of
instruments, a $3.5 million non-cash impairment charge to write-off the
developed technology acquired from InstruNor and a $2.5 million increase in
operating expenses.

Genomics. Genomics loss from operations increased by $16.7 million, or 164%, for
the year ended December 31, 2022 compared to the year ended December 31, 2021,
primarily due to a $20.5 million reduction in gross profit driven by lower
revenues and lower product and service margins. The unfavorable impact of these
items was partially offset by a $4.8 million reduction in operating expense,
which was primarily attributable to a $3.6 million reduction in R&D-related
expense as a result of targeted program reductions.

Corporate expenses. Corporate expenses include general and administrative expenses for functions shared by both operating segments such as executive management, human resources, and finance.

Interest expense increased by $0.5 million, or 13%, for the year ended
December 31, 2022 compared to the year ended December 31, 2021, principally due
to the $10.0 million Term Loan, which originated on August 1, 2021 and remained
fully drawn throughout 2022, as well as the Bridge Loans, which originated in
January 2022 and accrued interest until converted into Series B Redeemable
Preferred Stock in April 2022 as discussed below.

The Purchase Agreements for the issuance of 225,000 shares of Series B
Redeemable Preferred Stock for $225 million were accounted for as forward sales
contracts and recorded at fair value in accordance with ASC 480, Distinguishing
Liabilities from Equities. The fair value of the payable portion of the Purchase
Agreements was determined to be $285.1 million on April 4, 2022, the closing
date of the Private Placement Issuance. The $60.1 million loss on the forward
sales of Series B Preferred Stock for the twelve months ended December 31, 2022
reflects the increase in the share price of our common stock from $2.84 per
share at the inception of the Agreements to $3.99 per share on April 4, 2022.

Applying the guidance in ASC 825, Financial Instruments, we elected to record
the Bridge Loans, which commenced on January 4, 2022 at their fair value. The
change in fair value of the Bridge Loans from inception to their conversion on
April 4, 2022 was recorded as a loss on Bridge Loans. The fair value of the
Bridge Loans was largely driven by the value of our common stock and the value
of the Series B Preferred Stock into which they were converted. The loss on
Bridge Loans of $13.7 million in 2022 was largely driven by the increase in the
price of our common stock from inception to the conversion date.

Refer to Note 3 within our consolidated financial statements for additional details relating to the Series B Redeemable Preferred Stock and the Bridge Loans.



In 2022, we recognized the final $0.2 million of income under the NIH Contract
from amounts received in excess of amounts spent on capital expenditures and
operating expenses. The $0.2 million recognized in 2022 increased the amount of
cumulative income recognized under the agreement to $7.3 million.

Income Tax Benefit



Our tax provision is generally driven by our foreign operations and by discrete
items, such as changes in our valuation allowances or adjustments made when
finalizing our tax returns. Depending on the relative value of these items, we
can either have either a tax benefit or expense in any given period.

We recorded a tax benefit of $2.8 million, or an effective tax rate benefit of
1.5%, for the year ended December 31, 2022 compared to a tax benefit of $4.4
million, or an effective tax rate benefit of 6.9%, for the year ended
December 31, 2021. The reduced tax benefit in 2022 compared to 2021 was
primarily the result of changes in the deferred tax expense related to foreign
operations, which generated significant tax benefit in prior years.

Liquidity and Capital Resources

Sources of Liquidity



As of December 31, 2022, our principal sources of liquidity consisted of $165.8
million of cash and cash equivalents, and short-term investments. We expect
these sources will be sufficient to support the operations of our business and
any debt maturities for at least the next 12 months from the date of filing this
Annual Report. Our future capital needs will depend upon many factors, including
the market acceptance of our products and services; the effectiveness of our
business improvement initiatives and restructuring program launched in August
2022; the costs and pace of developing new products; the costs of supporting
sales growth; product quality; and the costs and timing of acquiring other
businesses, assets or technologies.

Net Cash Used in Operating Activities. We derive cash flows from operations
primarily by collecting amounts due from sales of our products and services, and
from fees earned under product development, license and grant agreements. Our
cash flows from operating activities are also significantly influenced by our
use of cash for operating expenses and working capital to support the business.
We have historically experienced negative cash flows from operating activities
as we have expanded our business and built our infrastructure domestically and
internationally.

Net cash used in operating activities in 2022 was $89.4 million. and consisted
of a net loss of $190.1 million partially offset by non-cash items of
$116.2 million and cash used in assets and liabilities of $15.5 million.
Non-cash items included a $60.1 million loss on forward sale of Series B
Preferred Stock, depreciation and amortization of $15.0 million, stock-based
compensation expense of $14.9 million, a $13.7 million loss on Bridge Loans, a
$7.9 million provision for excess and obsolete inventory, and a $3.5 million
impairment charge for InstruNor development technology. The net cash used in
assets and liabilities was primarily due to a $8.5 million increase in
inventory, a $6.0 million decrease in other current liabilities, a $3.5 million
decrease in deferred revenues, and a $2.8 million decrease of accounts payable.
This is partially offset by increased accrued compensation and benefits of $4.1
million including accruals for restructuring expenses, and a $1.1 million
reduction of accounts receivable.

Net Cash Used in Investing Activities. Our primary investing activities consist
of purchases, sales, and maturities of our short-term investments and capital
expenditures for manufacturing, laboratory, and computer equipment and software
to support our infrastructure and workforce. We expect to continue to incur
costs for capital expenditures to improve manufacturing efficiencies and
strengthen our information technology and network security. However, we may
choose to decrease or defer certain capital expenditures and development
activities, while further optimizing our organization.

Net cash used in investing activities in 2022 was $88.1 million, which primarily
consists of $137.3 million for the purchase of investments in short-term
securities, partially offset by $53.0 million of cash receipts from maturities
of such securities.

Net Cash Provided by Financing Activities. Net cash provided by financing
activities totaled $230.8 million in 2022. The principal sources of cash were
$25.0 million of proceeds from the receipt of the Bridge Loans in January 2022
and $225 million of proceeds from the issuance of Series B Preferred Stock in
April 2022. The Bridge Loans automatically converted into Series B Preferred
Stock upon the completion of the preferred stock financing.

The principal uses of cash were $12.5 million for equity issuance costs related
to the Series B Preferred Stock and $6.8 million for the repayment of advances
under the Revolving Credit Facility.

Purchase Obligations and Commitments



Purchase obligations consist of contractual and legally binding commitments to
purchase goods and services. Our purchase obligations with suppliers specify all
significant terms, including fixed, minimum or variable price provisions , and
the approximate timing of the transaction The majority of our contracts are
cancellable with little or no notice or penalty. However, once a vendor has
incurred costs to fulfill a contract with us, and which costs cannot be
otherwise deployed, we are liable for those costs upon cancellation. For
example, if a supplier has purchased raw materials to produce a good for us, and
those goods cannot be returned or otherwise used by our vendor, we are obligated
to reimburse them for the costs they incurred. As of December 31, 2022, these
purchase commitments totaled $13.5 million. Capital expenditure commitments as
of December 31, 2022 were immaterial. In addition, we have certain
non-cancellable commitments with service providers that are not material in the
aggregate.

We have additional obligations beyond the purchase of goods and services, including the following:



•Contingent obligations to our Series B Redeemable Preferred Stockholders. See
Note 3 Private Placement Issuance- Series B Preferred Stock- Change of Control
Provisions and Liquidation Rights.

•Principal amounts due under our debt obligations, including end-of-term fees,
totaled $66.2 million at December 31, 2022, of which $2.1 million is due and
payable in 2023. See Note 9 Debt for additional information.

•Future payments for operating lease obligations at December 31, 2022 totaled
$37.8 million, of which $3.7 million is expected to be paid in 2023. See Note 10
Leases for additional information.

•Additional information on our obligations under license and patent agreements,
and indemnification agreements entered into in the ordinary course of business
is provided in Note 17 Commitments and Contingencies.

The expected timing of payments of our obligations is estimated based on current
information. Timing of payments and actual amounts paid may be different,
depending on the timing of receipt of goods or services, or changes to
agreed-upon amounts for some obligations. In addition, some of our future
purchasing needs are not current contractual obligations and are therefore not
included in the commitment amounts above because they are not handled through
binding contracts or are not fulfilled by vendors on a purchase order basis
within short time horizons.

Capital Resources

At December 31, 2022 and December 31, 2021, our working capital, excluding deferred revenues, deferred grant income, and restricted cash, was $179.8 million and $38.0 million, respectively, including cash, cash equivalents and short-term investments of $165.8 million and $28.5 million, respectively.

Repurchase of Common Shares



On November 23 2022, our board of directors authorized the repurchase of up to
$20.0 million of shares of the Company's common stock in the open market or in
negotiated transactions through December 31, 2023. The repurchases are expected
to be funded by cash on hand. We repurchased a total of 422,309 shares of common
stock under this program at a total cost of $0.6 million, or an average of $1.33
per share in 2022. As of December 31, 2022, the Company had a remaining
authorization to repurchase up to $19.4 million of shares under this program.
The timing and amount of future repurchases will depend upon

                                       57

--------------------------------------------------------------------------------

several factors, including market and business conditions, the daily trading
volume of our stock and applicable SEC regulations. Repurchases may be suspended
or discontinued at any time.

2014 Notes and 2019 Notes

In February 2014, we closed an underwritten public offering of our 2014 Notes.
Pursuant to the Indenture governing the 2014 Notes, holders of the 2014 Notes
have the right, subject to certain conditions specified in such indenture, to
require the Company to repurchase all or a portion of their 2014 Notes on each
of February 6, 2021, February 6, 2024, and February 6, 2029, at a repurchase
price in cash equal to 100% of the principal amount of the 2014 Notes plus
accrued and unpaid interest. On February 6, 2021, holders of $0.5 million of the
2014 Notes exercised their right for us to repurchase their notes in accordance
with this provision leaving $0.6 million of 2014 Notes outstanding at
December 31, 2022.

In November 2019, we closed a private placement of $55.0 million aggregate
principal amount of our 2019 Notes. The 2019 Notes bear interest at 5.25% per
annum, payable semiannually on June 1 and December 1 of each year, beginning on
June 1, 2020. The Notes mature on December 1, 2024, unless earlier repurchased
or converted pursuant to their terms. The 2019 Notes will be convertible at the
option of the holder at any point prior to close of business on the second
scheduled trading day preceding the maturity date. The initial conversion rate
of the 2019 Notes is 344.8276 shares of the Company's common stock per $1,000
principal amount of 2019 Notes (which is equivalent to an initial conversion
price of $2.90 per share). The conversion rate will be subject to adjustment
upon the occurrence of certain specified events but will not be adjusted for any
accrued and unpaid interest.

The 2019 Notes will also be convertible at our option upon certain conditions in
accordance with the terms of the indenture governing the 2019 Notes. On or after
December 1, 2021 to December 1, 2022, if the price of the Company's common stock
has equaled or exceeded 150% of the Conversion Price (as defined in the
indenture, currently $2.90 per share, subject to adjustment) for a specified
number of days (Issuer's Conversion Option), we may, at our option, elect to
convert the 2019 Notes in whole but not in part into shares of the Company. On
or after December 1, 2022, if the price of the Company's common stock has
equaled or exceeded 130% of the Conversion Price then in effect for a specified
number of days, we may, at our option, elect to convert the 2019 Notes in whole
but not in part into shares of the Company. The aggregate net carrying value of
the 2014 and 2019 Notes was $54.6 million at December 31, 2022.

The foregoing summaries of the 2014 Notes and the 2019 Notes are not complete and are qualified in their entirety by the applicable indentures, forms of global notes, and other agreements and documents filed with the SEC.

Revolving Credit Facility



On August 2, 2018, we entered into a Loan and Security Agreement with Silicon
Valley Bank (as amended the Revolving Credit Facility), which provides for
secured revolving loans in an aggregate principal amount of up to the lesser of
(i) $15.0 million or (ii) the sum of (a) 85% of our eligible receivables and (b)
50% of our eligible inventory, in each case, subject to certain limitations
(Borrowing Base), provided that the amount of eligible inventory that may be
counted towards the Borrowing Base shall be subject to a cap as set forth in the
Revolving Credit Facility.

In August 2021, we amended our Revolving Credit Facility to extend the maturity
date to August 2, 2023 and to provide for a new $10.0 million Term Loan Facility
(the Term Loan Facility and, together with the Revolving Credit Facility, the
Credit Facility). The Credit Facility is collateralized by substantially all our
property, other than intellectual property. The maturity date of the Term Loan
Facility is July 1, 2025, subject to the following condition: in the event the
principal amount of our convertible debt exceeds $0.6 million as of June 1, 2024
or if the maturity date of our 2019 Notes has not been extended beyond January
1, 2026 by that date, then the maturity date of the Term Loan Facility will be
June 1, 2024.The Amendment also added a financial covenant to the Credit
Facility, requiring us to maintain a minimum Adjusted Quick Ratio of at least
1.25 to 1.00 and a Liquidity requirement greater than $20.0 million.

The interest rate on advances made under the Revolving Credit Facility is the
greater of (i) prime rate plus 0.50% or (ii) 5.25% per annum. Interest on any
outstanding advances is due and payable monthly and the principal balance is due
at maturity though loans can be prepaid at any time without penalty. Fees for
Revolving Credit Facility include an annual commitment fee of $112,500 and a
quarterly unused line fee based on the Borrowing Base. As of December 31, 2022,
there were no borrowings under the Revolving Credit Facility and the total
availability was $9.2 million. We are in compliance with all the terms and
conditions of the Revolving Credit Agreement as of December 31, 2022.

On March 10, 2023, Silicon Valley Bank was announced as closed by the California Department of Financial Protection and Innovation, and the Federal Deposit Insurance Corporation has been appointed as a receiver. As a result, we no longer expect to be able to draw on the Revolving Credit Facility.


                                       58

--------------------------------------------------------------------------------

Term Loan



As of December 31, 2022, the carrying value of the Term Loan Facility was
$10.3 million and it was fully drawn. Interest on the term loan accrues on the
outstanding principal amount thereof at the greater of (i) a floating per annum
rate equal to three quarters of one percentage point (0.75%) above the prime
rate (as customarily defined), or 4% with a final payment equal to 6.5% of the
aggregate original principal amounts of each term loan advance due on the
earlier of the maturity date of the Term Loan Facility, the acceleration of the
term loan advances or any prepayment of a term loan advance. Interest is payable
monthly. The principal amount of the term loan advances is repayable beginning
on August 1, 2023, in twenty-four equal monthly installments. The $2.1 million
current portion of the term-loan represents principal repayments that will be
made in 2023. The effective interest rate on the Term Loan Facility, reflecting
the impact of debt issuance costs, the end-of-term fee and expected timing of
principal repayment was 9.3% per annum as of December 31, 2022.

Series B Preferred Stock



On April 4, 2022, we completed the Private Placement Issuance, issuing 255,559
shares of Series B Preferred Stock. The rights, preferences and privileges of
the Series B Preferred Stock are set forth in the Series B-1 Certificate of
Designations and Series B-2 Certificate of Designations (collectively, the
Series B Certificates of Designations). The Series B Preferred Stock ranks
senior to our common stock with respect to dividend rights, redemption rights
and rights on the distribution of assets on any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company. The
holders of Series B Preferred Stock are entitled to participate in all dividends
declared on our common stock on an as-converted basis, on the terms and subject
to the conditions set forth in the Series B Certificates of Designations.

The following is a brief summary of the conversion rights and other key provisions of the Series B Preferred Stock:

Holder Voluntary Conversion Rights



The Series B Preferred Stock is convertible at the option of the holders thereof
at any time into a number of shares of common stock equal to the Conversion Rate
(as defined in the Series B Certificates of Designations), which is initially
294.1176 shares of common stock per share of Series B Preferred Stock, in each
case subject to certain adjustments and certain limitations on conversion.

Issuer Call Provision



At any time after the fifth anniversary of the closing of the Private Placement
Issuance, if the last reported sale price of the common stock is greater than
250% of the Conversion Price (as defined in the Series B Certificates of
Designations) as of such time for at least 20 consecutive trading days, we may
elect to convert all of the outstanding shares of Series B Preferred Stock into
shares of common stock.

Issuer Redemption Provision



After the seventh anniversary of the closing of the Private Placement Issuance,
subject to certain conditions, we may, at our option, redeem all of the
outstanding shares of Series B Preferred Stock at a redemption price per share
of Series B Preferred Stock, payable in cash, equal to the Liquidation
Preference (as defined in the Series B Certificates of Designations).

Change of Control Provisions



If we undergo certain change of control transactions, each holder of outstanding
shares of Series B Preferred Stock will have the option, subject to the holder's
right to convert all or a portion of the shares of Series B Preferred Stock held
by such holder into common stock, to require us to purchase all or a portion of
such holder's outstanding shares of Series B Preferred Stock that have not been
converted into common stock at a purchase price per share of Series B Preferred
Stock, payable in cash, equal to the greater of (A) the Liquidation Preference
of such share of Series B Preferred Stock, and (B) the amount of cash and/or
other assets that such holder would have been entitled to receive if such holder
had converted such share of Series B Preferred Stock into common stock
immediately prior to the change of control transaction (Change of Control Put).

In the event of a change of control in which we are not expected to be the
surviving corporation or if our common stock will no longer be listed on a U.S.
national securities exchange, we will have a right to redeem, subject to the
holder's right to convert into common stock prior to such redemption, all of
such holder's shares of Series B Preferred Stock, or if a holder exercises the
Change of Control Put in part, the remainder of such holder's shares of Series B
Preferred Stock, at a redemption price per share payable in cash, equal to the
greater of (A) the Liquidation Preference of such share of Series B Preferred
Stock, and (B) the amount of cash and/or other assets that the holder would have
received if such holder had converted such share of Series B Preferred Stock
into common stock immediately prior to the change of control transaction.

                                       59

--------------------------------------------------------------------------------

Liquidation Rights



In the event of any voluntary or involuntary liquidation, dissolution or winding
up of the affairs of the Company, the Series B Preferred Stock has a liquidation
preference equal to the greater of (i) the Liquidation Preference (as defined in
the Series B Certificates of Designations, currently $3.40) and (ii) the amount
per share of Series B Preferred Stock that such holder would have received had
all holders of Series B Preferred Stock, immediately prior to such voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Company, converted all shares of Series B Preferred Stock into common stock
pursuant to the terms of the Series B Certificates of Designations (without
regard to any limitations on conversion contained therein).
