Consistent with this approach, we seek to retain exclusive rights to the benefits of certain of our small molecule drug programs by developing drug candidates from those programs internally and to collaborate with third parties with respect to the discovery, development and commercialization of small molecule and biotherapeutic drug candidates for other targets, particularly when the collaboration provides us with access to expertise and resources that we do not possess internally or are complementary to our own.  We have established drug discovery and development collaborations with a number of leading pharmaceutical and biotechnology companies which generated near-term cash while offering us the potential to retain economic participation in products our collaborators develop through the collaboration.  In addition, we have established collaborations and license agreements with other leading pharmaceutical and biotechnology companies, research institutes and academic institutions under which we received fees and, in some cases, are eligible to receive milestone and royalty payments, in return for granting access to some of our technologies and discoveries.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Lexicon Pharmaceuticals, Inc. was incorporated in Delaware in July 1995, and commenced operations in September 1995.

Under the securities purchase agreement, as amended and supplemented (the "securities purchase agreement"), and after accounting for the $181.5 million in net proceeds from our public offering and concurrent private placement of common stock in March 2010, Invus, L.P. and its affiliate Invus C.V., which we collectively refer to as Invus, have the right to require us to initiate a pro rata rights offering to our stockholders providing all stockholders with non-transferable rights to acquire shares of our common stock in an aggregate amount of up to approximately $163.0 million.  Invus may exercise its right to require us to conduct such a rights offering by giving us notice within a period of one year beginning on February 28, 2011, which will be extended by the number of days during such period that Invus is not permitted under the securities purchase agreement to initiate the rights offering as a result of any &#8220;blackout period&#8221; in connection with certain public offerings of our common stock.

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 maintain for this purpose as the &#8220;holders&#8221; 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 &#8220;indirect holders&#8221; 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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Book-Entry Holders </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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'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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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 nominee. 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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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'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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Street Name Holders </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in their own names or in &#8220;street name.&#8221; 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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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. </font></div><br><div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;">17</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><a style="text-decoration:underline;color:#0000FF;" href="#sAB2574C176C9D8F5C1244233C90630EA"><font style="font-family:inherit;font-size:10pt;">Table of Contents</font></a></div></div><br><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Legal Holders </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the 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 holders, and not the indirect holders, of the securities. Whether and how the holders contact the indirect holders is up to the holders. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Special Considerations for Indirect Holders </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out: </font></div><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">how it handles securities payments and notices;  </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">whether it imposes fees or charges;  </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">how it would handle a request for the holders' consent, if ever required;  </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">whether and how you can instruct it to send you securities registered in your own name so you can be a holder, if that is permitted in the future;  </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and  </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:9px;font-family:Times New Roman; font-size:10pt; width:100%;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">if the securities are in book-entry form, how the depositary's rules and procedures will affect these matters.  </font></div></td></tr></table><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Global Securities </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">A global security is a security that represents one or any other number of individual securities held by a depositary.

Beneficial interests must be held by means of an account with a broker, bank 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. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.

The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale.  Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters.  Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all of the offered securities if they purchase any of them.  The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In connection with the sale of our securities, underwriters, brokers, dealers or agents may receive compensation from us or purchasers of securities for whom they may act as agents, in the form of discounts, concessions or commissions.  Underwriters, dealers and agents that participate in the distribution of our securities may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of securities by them may be deemed to be underwriting discounts and commissions under the Securities Act.  Any person who may be deemed to be an underwriter will be identified, and the compensation received from us will be described, in the prospectus supplement.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market.  These transactions may include over-allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering.  The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the securities sold for their account may be reclaimed by the syndicate if those securities are repurchased by the syndicate in stabilizing or covering transactions.  These activities may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and, if commenced, may be discontinued at any time.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">If dealers or brokers acting as dealers are used in the sale of the securities, we will sell the securities to such dealers or brokers as principals.  The dealers or brokers acting as dealers may then resell such securities to the public at varying prices to be determined by such dealers or brokers at the time of resale.  The names of dealers or brokers acting as dealers and the terms of the transaction will be set forth in the prospectus supplement relating to such securities.  We may sell the securities directly or through agents designated by us from time to time.  Any agent involved in the offer or sale of the securities will be named, and any commissions that we pay to such agent will be set forth, in the prospectus supplement relating to such securities.  Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We may sell securities directly, in which case no underwriters or agents would be involved.

The terms of any such sales will be described in the prospectus supplement relating thereto.  Pursuant to any standby underwriting agreement entered into in connection with a rights offering to our stockholders, persons acting as standby underwriters may receive a commitment fee for all securities underlying the rights that the underwriter commits to purchase on a standby basis.  Additionally, prior to the expiration date with respect to any rights, any standby underwriters in a rights offering to our stockholders may offer such securities on a when-issued basis, including securities to be acquired through the purchase and exercise of rights, at prices set from time to time by the standby underwriters.  After the expiration date with respect to such rights, the underwriters may offer securities of the type underlying the rights, whether acquired pursuant to a standby underwriting agreement, the exercise of the rights or the purchase of such securities in the market, to the public at a price or prices to be determined by the underwriters.  The standby underwriters may thus realize profits or losses independent of the underwriting discounts or commissions paid by us.  If we do not enter into a standby underwriting agreement in connection with a rights offering to our stockholders, we may elect to retain a dealer-manager to manage such a rights offering for us.  We also may enter into a standby arrangement with other purchasers pursuant to which such purchasers may be required to purchase any securities remaining unsubscribed for after such offering.  Any such dealer-manager may offer securities of the type underlying the rights acquired or to be acquired pursuant to the purchase and exercise of rights and may thus realize profits or losses independent of any dealer-manager fee paid by us.</font></div><br><div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;">21</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><a style="text-decoration:underline;color:#0000FF;" href="#sAB2574C176C9D8F5C1244233C90630EA"><font style="font-family:inherit;font-size:10pt;">Table of Contents</font></a></div></div><br><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">If Invus elects to exercise its right to require us to initiate a rights offering to our stockholders, Invus would be required to purchase its pro rata portion of the offering.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">All securities we offer, other than common stock and other securities issued upon a reopening of a previous series, will be new issues of securities with no established trading market.

the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer,

corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.   </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Lexicon's restated certificate of incorporation, as amended, and restated bylaws provide that indemnification shall be to the fullest extent permitted by the DGCL for all current or former directors or officers.
