listed on the Nasdaq Global Select Market under the trading symbol &#147;FGEN.&#148; On February&nbsp;20, 2025, the last reported sale price of our common stock was $0.7724 per share. </P>

normal trading and sales practices, on mutually agreed terms between BofA and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:9pt; font-family:Times New Roman">Under the Sales Agreement, we may also sell common stock to BofA as principal for its own account, at a price to be agreed upon at the time of

any shares of common stock sold under the Sales Agreement. In connection with the sale of the common stock on our behalf, BofA may be deemed to be an &#147;underwriter&#148; within the meaning of the Securities Act and the compensation of BofA may

partnership with Fortis Therapeutics, we are developing FG-3246, a first-in-class antibody-drug conjugate targeting CD46, for the treatment of metastatic castration-resistant prostate cancer and potentially other cancers. This program also includes
the development of FG-3180, an associated CD46-targeted PET biomarker and imaging agent. We anticipate initiation of a Phase 2 monotherapy dose optimization study of FG-3246 for the treatment of mCRPC in the second quarter of 2025. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Prior to focusing on FG-3246 and our other clinical programs, we and our collaboration partners developed roxadustat (<FONT

EVRENZO<SUP STYLE="font-size:75%; vertical-align:top">TM</SUP>), which is currently approved in China, Europe, Japan, and numerous other countries for the treatment of anemia in chronic kidney disease patients on dialysis and not on dialysis.
</FONT></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On February&nbsp;20, 2025, we and our indirect subsidiary FibroGen China Anemia Holdings, Ltd. entered into a share purchase
agreement with AstraZenec Treasury Limited, a subsidiary of AstraZeneca plc, or AstraZenaca, pursuant to which we agreed to sell all of the issued and outstanding equity interests of FibroGen International (Hong Kong) Ltd., or FibroGen
International, to AstraZeneca for an aggregate purchase price of approximately $160&nbsp;million, comprised of $85&nbsp;million in cash for the enterprise value of FibroGen International, plus an additional cash amount equal to the cash held in
China by FibroGen International and its subsidiaries, currently anticipated to be approximately $75&nbsp;million, as of the closing. The transaction is expected to close by <FONT STYLE="white-space:nowrap">mid-2025,</FONT> and is subject to
customary closing conditions and closing deliverables, including receipt of regulatory approval from the China State Administration for Market Regulation. At the closing, we intend to repay our term loan facility with Morgan Stanley Tactical Value.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">AstraZeneca is our long-time commercialization partner for roxadustat in greater China and South Korea. Upon the closing, we will assign
to AstraZeneca all rights to roxadustat in China, Hong Kong, and Macao, including rights to manufacture, develop, distribute, and commercialize roxadustat. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We will retain the rights to roxadustat in the United States, Canada, Mexico, and in all markets not held by AstraZeneca or licensed to
Astellas Pharma Inc. Roxadustat is not approved for commercialization in any indication in the United States, Canada, or Mexico. Astellas Pharma is commercializing roxadustat (Evrenzo<SUP STYLE="font-size:75%; vertical-align:top">TM</SUP>) in Europe
and Japan to treat anemia under two development and commercialization license agreements: one for Japan, and one for Europe, the Commonwealth of Independent States, the Middle East and South Africa. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We intend to continue to evaluate a development plan for roxadustat in anemia associated with lower-risk myelodysplastic syndrome, a
high-value indication with significant unmet medical need. We are planning for a meeting with the FDA in the second quarter of 2025 to determine the potential next steps for the development program for roxadustat in the United States. </P>

against our crystal form patents in Europe and China, and against our photostable formulations patent in Europe. European Patent No.&nbsp;2872488, or the 488 Patent, which claimed the commercial crystalline form of roxadustat, was revoked in
opposition, and the decision is not under appeal. While European Patent No.&nbsp;3470397, or the 397 Patent, which is a divisional of the 488 Patent, was upheld in opposition, the opponents have appealed the decision. European Patent
No.&nbsp;3003284, or the 284 Patent, which claims photostable formulations of roxadustat, was upheld in opposition, but the opponents appealed the decision and the patent was revoked, with no further appeals possible. In China, three roxadustat
crystal form patents were revoked in first-round proceedings and two revocations were upheld on first appeal; however, all decisions currently remain on appeal. Final resolution of ongoing proceedings in Europe and China will take time and we cannot
be assured that these patents will survive these proceedings as originally granted or at all. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Associated with Our Business </B></P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Investing in our common stock involves a high degree of risk. Before deciding whether to invest in our common stock, you should consider
carefully the risks and uncertainties described below and discussed under the heading &#147;Risk Factors&#148; contained in our most recent Annual Report on Form <FONT STYLE="white-space:nowrap">10-K,</FONT> and in our subsequent Quarterly Report on
Form <FONT STYLE="white-space:nowrap">10-Q,</FONT> as well as any amendments thereto reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus supplement in their entirety, together with other information
in this prospectus supplement and accompanying prospectus, the documents incorporated by reference herein and therein, and any free writing prospectus that we may authorize for use in connection with this offering. The risks described in these
documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future
results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial
condition, results of operations or cash flow could be harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below titled
&#147;Special Note Regarding Forward-Looking Statements.&#148; </I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Related to This Offering </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Management will have broad discretion as to the use of the net proceeds from this offering, and may not use the proceeds effectively. </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Because we have not designated the amount of net proceeds from this offering to be used for any particular purpose, our management will have
broad discretion as to the application of any net proceeds from this offering and could use them for purposes other than those contemplated at the time of the offering. Our management may use any net proceeds for corporate purposes that may not
improve our financial condition or market value. If our management applies these proceeds in a manner that does not yield a significant return, if any, on our investment of these net proceeds, it could compromise our ability to pursue our growth
strategy and adversely affect the market price of our common stock. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>You may experience immediate and substantial dilution as a result of this
offering. </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The offering price per share in this offering may exceed the net tangible book deficit per share of our common stock
outstanding prior to this offering. Assuming an aggregate of 38,839,979 shares of our common stock are sold in this offering, based on an assumed sale price of $0.7724 per share, the last sale price of a share of our common stock on the Nasdaq
Global Select Market on February&nbsp;20, 2025, you will experience immediate dilution of $2.0123 per share, representing the difference between the price you pay and our as adjusted net tangible book deficit per share as of September&nbsp;30, 2024,
after giving effect to this offering, and the assumed public offering price. The exercise of outstanding stock options and vesting and settlement of outstanding restricted stock units may result in further dilution of your investment. See the
section titled &#147;Dilution&#148; below for a more detailed illustration of the dilution you would incur if you participate in this offering. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>The
actual number of shares of common stock we will issue under the Sales Agreement, at any one time or in total, is uncertain. </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Subject to
certain limitations in the Sales Agreement and compliance with applicable law, we have the discretion to deliver an issuance notice to BofA at any time throughout the term of the Sales Agreement. The number of shares of common stock that are sold
through BofA after delivering an issuance notice will fluctuate based on the market price of the shares of common stock during the sales period and limits we set with BofA. Because the price per share of each shares of common stock sold will
fluctuate based on the market price of our shares of common stock during the sales period, it is not possible at this stage to predict the number of shares of common stock that will be ultimately issued. </P>

the sales period, any limits we may set with BofA in any applicable placement notice and the demand for our common stock. Because the price per share of each share sold pursuant to the Sales Agreement will fluctuate over time, it is not currently

demand, to vary the timing, prices and number of shares sold in this offering. In addition, subject to the final determination by our board of directors or any restrictions we may place in any applicable placement notice delivered to BofA, there is
no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid. </P>

AstraZeneca will not be obligated to purchase FibroGen International. In the event that the sale is not completed, the announcement of the termination of the share purchase agreement may adversely affect the trading price of our common stock and our
business. In addition, if the sale of FibroGen International to AstraZeneca is not completed, our Board of Directors, may evaluate other strategic alternatives with respect to FibroGen International, if any are available, which alternatives may not
be as favorable to our stockholders as the proposed sale to AstraZeneca, and may not result in any definitive transaction or enhance stockholder value. </P>

capital in the United States, we will not have sufficient liquidity to continue operations in the United States for the twelve months from the date of this prospectus supplement and will not be able to comply with certain of our debt covenants under
our senior secured term loan facilities, including the financial covenant that requires a minimum balance of $30&nbsp;million of unrestricted cash and cash equivalents to be held in accounts in the United States. Upon an event of default, our senior
secured term loan facilities could become immediately due and payable. We have evaluated measures to repatriate additional cash from our China operations and we believe the sale of FibroGen International represents the most efficient way to
repatriate the entirety of our cash from China upon closing of the transaction. There is also the potential that we raise additional funds in the United States at any time through equity, equity-linked, or debt financing arrangements or from other
sources. There can be no assurances that these plans will be successful. As a result of these factors, we have determined that there is substantial doubt about our ability to continue as a going concern within 12 months after the date of this

However, if it appears to the Nasdaq staff that we will not be able to cure the deficiency, or if we do not meet the other listing standards, Nasdaq could provide notice that our common stock will become subject to delisting. In the event we receive
notice that our common stock is being delisted, Nasdaq rules permit us to appeal any delisting determination by the Nasdaq staff to a Hearings Panel. We expect that our common stock would remain listed pending the Hearing Panel&#146;s decision. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Delisting from the Nasdaq Global Select Market or any Nasdaq market could make trading our common stock more difficult for investors,
potentially leading to declines in our share price and liquidity. In addition, without a Nasdaq market listing, stockholders may have a difficult time getting a quote for the sale or purchase of our common stock, the sale or purchase of our common
stock would likely be made more difficult and the trading volume and liquidity of our common stock could decline. Delisting from Nasdaq could also result in negative publicity and could also make it more difficult for us to raise additional capital.
The absence of such a listing may adversely affect the value accorded by other parties. Further, if we are delisted, we would also incur additional costs under state blue sky laws in connection with any sales of our securities. These requirements
could severely limit the market liquidity of our common stock and the ability of our stockholders to sell our common stock in the secondary market. If our common stock is delisted by Nasdaq, our common stock may be eligible to trade on an <FONT
STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">over-the-counter</FONT></FONT> quotation system, such as the OTCQB market, where an investor may find it more difficult to sell our common stock or obtain accurate quotations as to the
market value of our common stock. We cannot assure you that our common stock, if delisted from Nasdaq, will be listed on another national securities exchange or quoted on an <FONT STYLE="white-space:nowrap">over-the</FONT> counter quotation system.
If our common stock is delisted, it may come within the definition of &#147;penny stock&#148; as defined in the Exchange Act, and would be covered by Rule <FONT STYLE="white-space:nowrap">15g-9</FONT> of the Exchange Act. That rule imposes
additional sales practice requirements on broker-dealers who sell securities to persons other than established customers and accredited investors. For transactions covered by Rule <FONT STYLE="white-space:nowrap">15g-9,</FONT> the broker-dealer must
make a special suitability determination for the purchaser and receive the purchaser&#146;s written agreement to the transaction prior to the sale. Consequently, Rule <FONT STYLE="white-space:nowrap">15g-9,</FONT> if it were to become applicable,
would affect the ability or willingness of broker-dealers to sell our securities, and accordingly would affect the ability of stockholders to sell their securities in the public market. These additional procedures could also limit our ability to
raise additional capital in the future. </P>

&#147;foreign financial institution&#148; (as specifically defined under these rules) unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities
substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners). FATCA also generally
imposes a U.S. federal withholding tax of 30% on certain payments to a <FONT STYLE="white-space:nowrap">&#147;non-financial</FONT> foreign entity&#148; (as specifically defined under these rules) unless such entity provides the withholding agent
with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding substantial direct and indirect U.S. owners of the entity. An intergovernmental agreement between the United States
and an applicable foreign country may modify those requirements. The withholding tax described above will not apply if the foreign financial institution or <FONT STYLE="white-space:nowrap">non-financial</FONT> foreign entity otherwise qualifies for
an exemption from the rules. Under certain circumstances, a <FONT STYLE="white-space:nowrap">Non-U.S.</FONT> Holder might be eligible for refunds or credits of such taxes. FATCA currently applies to dividends paid on our common stock and would have
applied also to payments of gross proceeds from the sale or other disposition of our common stock. However, the U.S. Treasury Department has released proposed regulations under FATCA providing for the elimination of the U.S. federal withholding tax
of 30% applicable to gross proceeds of a sale or other disposition of property of a type that can produce U.S. source dividends or interest. Under these proposed Treasury Regulations (which may be relied upon by taxpayers prior to finalization),
FATCA will not apply to gross proceeds from sales or other dispositions of our common stock. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Prospective investors are encouraged to

the risks and uncertainties described under the section titled &#147;Risk Factors&#148; contained in the applicable prospectus supplement and any related free writing prospectus, and discussed under the section titled &#147;Risk Factors&#148;
contained in our most recent Annual Report on Form <FONT STYLE="white-space:nowrap">10-K</FONT> and in our most recent Quarterly Report on Form <FONT STYLE="white-space:nowrap">10-Q,</FONT> as well as any amendments thereto reflected in subsequent
filings with the SEC, which are incorporated by reference into this prospectus in their entirety, together with other information in this prospectus, the documents incorporated by reference and any free writing prospectus that we may authorize for
use in connection with this offering. The risks described in these documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other
factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If
any of these risks actually occur, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your
investment. Please also read carefully the section below titled &#147;Special Note Regarding Forward-Looking Statements&#148;&nbsp;and the section titled &#147;Forward-Looking Statements&#148; included in our most recent Annual Report on Form <FONT

proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify them
under Delaware law. We have entered and expect to continue to enter into agreements to indemnify our directors, officers and other employees as determined by our board of directors. With specified exceptions, these agreements provide for
indemnification for related expenses including, among other things, attorneys&#146; fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these bylaw provisions and

convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the
applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to
any supplemental indentures that specify the terms of a particular series of debt securities. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We will issue the debt securities under the
indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the
registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this
prospectus is a part or will be incorporated by reference from reports that we file with the SEC. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following summary of material

consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against
changes in our operations, financial condition or transactions involving us. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue the debt securities issued under the indenture

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail
below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the &#147;holders&#148; of those securities. These persons
are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as &#147;indirect holders&#148; of those securities. As we discuss
below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Book-Entry Holders </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue
securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary
on behalf of other financial institutions that participate in the depositary&#146;s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of
themselves or their customers. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Only the person in whose name a security is registered is recognized as the holder of that security.
Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all
payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so
under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global
security, through a bank, broker or other financial institution that participates in the depositary&#146;s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect
holders, and not holders, of the securities. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Street Name Holders </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may terminate a global security or issue securities in <FONT STYLE="white-space:nowrap">non-global</FONT> form. In these cases, investors
may choose to hold their securities in their own names or in &#147;street name.&#148; Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the
investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For
securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we will make all payments on those
securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors
who hold securities in street name will be indirect holders, not holders, of those securities. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Legal Holders </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the
legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of
a security or has no choice because we are issuing the securities only in global form. </P>

approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all
securities represented by the same global securities will have the same terms. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Each security issued in book-entry form will be
represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise
in the applicable prospectus supplement, DTC will be the depositary for all securities issued in book-entry form. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A global security may
not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under the section titled &#147;Special
Situations When a Global Security Will Be Terminated&#148; in this prospectus. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and
investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a bank, broker, or other financial institution that in turn has an account with the depositary or with
another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the security, but only an indirect holder of a beneficial interest in the global security. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will
be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held
through any book-entry clearing system. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Special Considerations For Global Securities </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The rights of an indirect holder relating to a global security will be governed by the account rules of the investor&#146;s financial
institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may authorize agents, dealers or underwriters to solicit offers by certain types of
institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe
the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We
may provide agents, dealers and underwriters with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents, dealers or underwriters may make with respect to
these liabilities. Agents, dealers and underwriters or their affilaites may engage in transactions with, or perform services for, us in the ordinary course of business. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">All securities we may offer, other than common stock, will be new issues of securities with no established trading market. Any underwriters
may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with
Regulation&nbsp;M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not
exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover
short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities
may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any underwriters, dealers or agents that are qualified market makers on the Nasdaq Global Select Market may engage in passive market making
transactions in our common stock on the Nasdaq Global Select Market in accordance with Regulation&nbsp;M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common
stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid
for such security; if all independent bids are lowered below the passive market maker&#146;s bid, however, the passive market maker&#146;s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the
market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received
by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement. </P>
