(a)                                 Request for Registration.

 

(1)                                 If the Company shall receive at any time after the date that is one year following the date of the closing of the IPO a written request from the Holders of at least 30% of the Registrable Securities that the Company file a registration statement under the 1933 Act, then the Company shall, within ten (10) days after the receipt thereof, give written notice of such request to all Holders and shall, subject to the limitations of Section 2(a)(2), use its best efforts to effect as soon as practicable, and in any event within ninety (90) days after the receipt of such request from the Holders initiating a request under this Section 2(a) (the “Initiating Holders”), the registration under the 1933 Act of all Registrable Securities which, within twenty (20) days after the Company mails such written notice, the Holders request to be so registered; provided, however, that the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 2(a)(1):

 

(A)                               While another registration statement (other than on Form S-3, S-4 or S-8) of the Company has been filed with the SEC and is not yet

 

3

 

effective or on or within one hundred eighty (180) days after the effective date of another registration statement (other than on Form S-3, S-4 or S-8) filed by the Company with the SEC;

 

(B)                               While another registration statement (other than on Form S-4 or S-8) of the Company has been requested or demanded to register shares of Common Stock issued or issuable upon conversion of shares of the Company’s Capital Stock that ranks senior to the Common Stock as to dividends and distribution of assets upon dissolution of the Company or while any such registration statement has been filed with the SEC and is not yet effective or on or within one hundred eighty (180) days after the effective date of any such registration statement (other than on Form S-4 or S-8) filed by the Company with the SEC.

 

(C)                               After the Holders have requested two such registrations pursuant to this Section 2(a)(1) and such registrations have been declared or ordered effective by the SEC, so long as the Company shall have complied with its obligations in this Agreement relating to such registrations; provided however, that if any Holder is unable to include in such registration any Registrable Securities that such Holder requests be included in any such registration, the Holders shall be entitled to one additional registration for each such registration from which any Registrable Securities are so excluded; or

 

(D)                               If the Company shall furnish to the Holders a certificate signed by the Chairman of the Board or the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company, as evidenced by a duly adopted resolution of the Board of Directors of the Company, it would be seriously detrimental to the Company or its stockholders for a registration statement to be filed at such time, then the Company’s obligation to use its best efforts to register, qualify or comply under this Section 2(a)(1) shall be deferred for a period (as specified in such resolution) not to exceed ninety (90) days from the date of receipt of such written request from the Initiating Holders; provided, however, that the Company may not utilize this right to delay fulfillment of a request more than once in any twelve-month period.

 

(2)                                 If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2(a) and the Company shall include such information in the written notice referred to in Section 2(a)(1).  In such event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in such underwriting (unless otherwise mutually agreed by a majority in interest of the Holders) to the extent provided herein.  All Holders proposing to distribute their securities through such underwriting shall (together with the Company, as provided in Section 2(d)(6)) enter into an underwriting agreement in usual and customary form with the underwriter or underwriters selected for such

 

4

 

underwriting by a majority in interest of the Initiating Holders and approved by the Company.  Notwithstanding any other provision of this Section 2(a), if the underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities which would otherwise be included in such underwritten offering pursuant hereto, and the number of Registrable Securities that may be included in such underwritten offering shall be allocated as follows:  (i) first, among persons who have the right to include shares in such registration statement pursuant to an agreement other than this Agreement, to the extent such other agreement affords such persons priority over the Holders to include their shares in such registration statement, and (ii) thereafter among the Holders who have elected to participate in such underwritten offering, in such proportion (as nearly as practicable) as the number of Registrable Securities held by each Holder bears to aggregate amount of Registrable Securities held by all such Holders until such Holders have included in the underwriting all Registrable Securities that such Holders have requested to be included in such registration, and (iii) thereafter, among all other persons who have the right to include shares in such registration, in such relative priorities as established by the agreement(s) under which such rights arise.  Without the consent of a majority in interest of the Initiating Holders, except as permitted by clause (i) of the immediately preceding sentence, no securities other than Registrable Securities shall be covered by such registration if the inclusion of such other securities would result in a reduction of the number of Registrable Securities covered by such registration or included in any underwriting or if, in the opinion of the managing underwriter, the inclusion of such other securities would adversely affect the marketing of such offering.

 

(b)                                 Company Registration.  If the Company at any time proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holders) any of its stock or other securities under the 1933 Act in connection with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities to participants in a Company stock plan, or a registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities), the Company shall, at least ten (10) days prior to the filing of any registration statement under the 1933 Act relating thereto, promptly give each Holder written notice of such registration, unless by the terms of any agreement between the Company and any holders of securities to which such registration relates the Holders are not permitted to include any Registrable Securities in such registration.  Such notice shall be given by mail and, concurrent with the deposit of such notice in the mail, by telephone line facsimile transmission to the Holders who have furnished telephone line facsimile transmission numbers to the Company.  Upon the written request of a Holder given within ten (10) days after such written notice by the Company is given to all Holders (which request shall specify the number of Registrable Securities to be included in such registration statement), the Company shall, subject to the provisions of Section 2(g), cause to be registered under the 1933 Act all of the Registrable Securities that such Holder has requested to be registered.

 

(c)                                  Form S-3 Registration.  In case the Company shall receive

 

5

 

from the Holders of at least 30% of the Registrable Securities (the “S-3 Initiating Holders”) a request that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by the S-3 Initiating Holder or S-3 Initiating Holders, the Company will:

 

(1)                                 promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

 

(2)                                 as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within ten (10) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 2(c):  (1) if Form S-3 is unavailable for such offering by the Holders; (2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $1,000,000, unless the Registrable Securities to be so registered are all the Registrable Securities held by the S-3 Initiating Holders; (3) if the Company shall furnish to the Holders a certificate signed by the Chairman of the Board or the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company, as evidenced by a duly adopted resolution of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 for a period of not more than ninety (90) days after receipt of the request of the S-3 Initiating Holder or S-3 Initiating Holders under this Section 2(c); provided, however, that the Company shall not utilize this right more than once in any twelve-month period; or (4) in any particular jurisdiction in which the Company would be required to qualify to do business, subject itself to taxation measured by its income or revenues if the Company is not otherwise subject to such taxation in such jurisdiction or to execute a general consent to service of process in any such case in effecting such registration, qualification or compliance.

 

(3)                                 Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the S-3 Initialing Holders.  All expenses incurred by the Company in connection with a registration requested pursuant to Section 2(c), including (without limitation) all registration, filing, qualification, printer’s and accounting fees and reasonable fees and disbursements of a single counsel for all Holders shall be borne by the Company.  Registrations effected pursuant to this Section 2(c) shall not be counted as demands for registration or registrations effected pursuant to Sections 2(a) or 2(b), respectively.

 

6

 

(d)                                 Obligations of the Company.  Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

 

(1)                                 Prepare and file with the SEC a registration statement with respect to such Registrable Securities on the appropriate form and use its best efforts to cause such registration statement to become effective on the earliest practicable date, and keep such registration statement effective for up to 180 days during which the applicable prospectus is available for use by the Holders whose Registrable Securities are included in such registration (or such shorter period of time, if an underwritten offering, as the underwriters need to complete the distribution of the registered offering, or until the Holders whose Registrable Securities are included in a particular registration have disposed of their Registrable Securities in such registration or such securities shall cease to be Registrable Securities by reason of clause (iii) of the definition of the term “Registrable Securities” in the case of a “shelf” registration on Form S-3 or any similar or successor “short-form” registration statement); provided, that the number of days that a registration statement shall be kept effective under this Section 2(d)(1) shall be increased for each day the effectiveness of such registration statement was suspended or halted, if at all.

 

(2)                                 Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the 1933 Act with respect to the disposition of all securities covered by such registration statement.

 

(3)                                 Furnish to each Holder a copy of all documents filed with the SEC and all correspondence from or to the staff of the SEC in connection with such registration.

 

(4)                                 Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the 1933 Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them.

 

(5)                                 Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or “blue sky” laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such state or jurisdiction.

 

(6)                                 In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriters of such offering and arrange for the Company’s independent public accountants to furnish such “comfort” and other letters in customary form for underwritten offerings and as otherwise required by such underwriting agreement.

 

7

 

(7)                                 Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the 1933 Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and use its best efforts to correct such misstatement or omission as soon as practicable.

 

(8)                                 Furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 2, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, opinions, dated such date, of counsel representing the Company in connection with such registration, in form, scope and substance as is customarily given in such a public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities.

 

(9                                     Cause all such Registrable Securities registered pursuant hereto to be listed on each securities exchange on which similar securities issued by the Company are then listed.

 

(10)                          Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

 

(11)                          Refrain from bidding for or purchasing any Common Stock or any right to purchase Common stock or attempting to induce any Person to purchase any such security or right if such bid, purchase or attempt would in any way limit the right of the Holders to sell Registrable Securities under such registration statement by reason of the limitations set forth in Regulation M under the 1934 Act.

 

(e)                                  Obligations of the Holders.  (1)  It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required in order to comply with any applicable law or regulation in connection with the registration of such Holder’s Registrable Securities or any qualification or compliance with respect to such Holder’s Registrable Securities and referred to in this Agreement.

 

(2)                                 The Holders hereby acknowledge that there may occasionally be times when the Company must suspend the use of a prospectus forming a part of

 

8

 

any registration statement filed pursuant to this Agreement until such time as an amendment to such registration statement has been filed by the Company and declared effective by the SEC or until the Company has amended or supplemented such prospectus. The Holders hereby covenant that they will not sell any securities pursuant to any such prospectus during the period commencing at the time at which the Company gives the Holders notice of the suspension of the use of any such prospectus and ending at the time the Company gives the Holders notice that the Holders may thereafter effect sales pursuant to any such prospectus. Notwithstanding anything herein to the contrary, the Company shall not suspend use of the registration statement by the Holders unless in the good faith determination of the Company such suspension is required by the federal securities laws, including, without limitation, the rules and regulations promulgated thereunder; provided, however, that (i) except as otherwise provided by clause (ii) below, if such suspension is required by the need for an amendment or supplement to the registration statement or the prospectus forming a part thereof, the Company shall promptly file such required amendments or supplements as shall be necessary for the disposition of the Registrable Securities to recommence and (ii) if the Board of Directors has determined in good faith that offers and sales pursuant to the prospectus forming part of the registration statement should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure that would be required in the registration statement would be premature or would have a Material Adverse Effect, the Company may suspend the use of the prospectus and defer the filing of any required amendment or supplement for the minimum period of time necessary to avoid such Material Adverse Effect; provided, further, that in the case of clause (ii) above, the Company shall not be entitled to exercise its right to block such sales or suspend use of such prospectus more than one time (not to exceed thirty (30) days) in any twelve-month period.

 

(3)                                 Each Holder agrees that any sale by such Holder of Registrable Securities pursuant to a registration statement covering Registrable Securities shall be sold in a manner described in the plan of distribution set forth therein and (A) if such sale is made through a broker, the Holder shall instruct such broker to deliver the prospectus to the purchaser or purchasers (or the broker or brokers therefore) in connection with such sale, shall supply copies of the prospectus to such broker or brokers and shall instruct such broker or brokers to deliver such prospectus to the purchaser in such sale or such purchaser’s broker, (B) if such sale is made in a transaction directly with a purchaser and not through the facilities of any securities exchange or market, the Holder shall deliver, or cause to be delivered, the prospectus to such purchaser; and (C) if such sale is made by any means other than those described in the immediately preceding clauses (A) and (B), the Holder shall otherwise use its best efforts to comply with the prospectus delivery requirements of the 1933 Act applicable to such sale.

 

(4)                                 Each Holder agrees that it will promptly notify the Company of any material changes in the information set forth in the registration statement regarding such Holder or its plan of distribution; each Holder agrees (a) to notify the Company in writing in the event that such Holder enters into any material agreement with a broker or a dealer for the sale of the Registrable Securities

 

9

 

through a block trade, special offering, exchange distribution or a purchase by a broker or dealer and (b) in connection with such agreement, to provide to the Company in writing the information necessary to prepare any supplemental prospectus pursuant to Rule 424(c) under the 1933 Act which is required with respect to such transaction.

 

(5)                                 Each Holder shall not take any action with respect to any distribution deemed to be made pursuant to the registration statement covering such Holder’s Registrable Securities, which would constitute a violation of Regulation M under the 1934 Act or any other applicable rule, regulation or law.

 

(6)                                 At the end of the period during which the Company is obligated to keep a registration statement current and effective as described in this Agreement, the Holders of Registrable Securities included in such registration statement shall discontinue sales of Registrable Securities pursuant to such registration statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such registration statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company.

 

(f)                                    Expenses of Registration. All expenses (other than underwriting discounts and commissions payable with respect to Registrable Securities sold in an offering) incurred by the Company in connection with registrations, filings or qualifications pursuant to Sections 2(a), 2(b) and 2(c) including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees (but not including any fees and disbursements of any counsel to any Holders) shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2(a) if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses), unless (a) the withdrawal is based upon material adverse information concerning the Company of which such Holders were not aware at the time of such request or any material misstatement or omission in any registration statement filed by the Company with the SEC in connection with such offering or (b) the Holders of a majority of the Registrable Securities being registered agree to forfeit the right to a demand registration pursuant to Section 2(a), in which event such right shall be forfeited by all Holders). If the Holders are required to pay such registration expenses, such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration or inclusion therein in proportion to the number of Registrable Securities for which registration was requested. If the Company is required to pay such registration expenses of a withdrawn offering pursuant to clause (a) above, then the Holders shall not forfeit their rights pursuant to Section 2(a) to a demand registration.

 

(g)                                 Underwriting Requirements. In connection with any offering involving an underwriting of shares being issued by the Company, the Company shall not be required under Section 2(b) to include a particular Holder’s securities in

 

10

 

such underwriting unless such Holder accepts the terms of the underwriting as agreed upon between the Company and the underwriters selected by it and as are consistent with this Agreement; provided, however, that a Holder shall not be required to make any representations or warranties other than with respect to itself and its Registrable Securities. If the total amount of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the amount of securities proposed to be sold by persons or entities other than the Company that the underwriters reasonably believe compatible with the success of the offering, then, except as otherwise agreed by the Company with holders of securities (other than Registrable Securities) to be included in such registration, the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters believe will be compatible with the success of the offering, but in no event shall (i) the Company be required to exclude from such registration shares held by any person who is entitled to include shares in such registration statement pursuant to an agreement other than this Agreement, except to the extent such other agreement permits the Company to exclude such shares from such registration before excluding or reducing pro rata the Holders’ Registrable Securities, (ii) in the IPO the total amount of securities, including Registrable Securities requested by the Holders to be included in the IPO, be reduced unless, subject to the immediately preceding clause (i), all other securities of the Company held by other stockholders of the Company are first entirely excluded from the IPO; or (iii) any shares being sold by a stockholder exercising a demand registration right similar to that granted in Section 2(a) be excluded from such offering.

 

(h)                                 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2 unless such injunction is sought by Holders of a majority of the Registrable Securities.

 

(i)                                    Indemnification. If any Registrable Securities are included in a registration statement under this Section 2:

 

(1)                                 To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, officers, members, investment advisors, Affiliates and directors of each Holder, any underwriter (as defined in the 1933 Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the 1933 Act or the 1934 Act against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the 1933 Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, liabilities, or expenses (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations of the Company (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in a registration statement filed pursuant to this Agreement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged

 

11

 

violation of the 1933 Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the 1933 Act, the 1934 Act or any state securities law in connection with this Agreement; and the Company will pay to each such Holder, the partners, officers, members, investment advisors, Affiliates and directors of each such Holder, each such underwriter or controlling party, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, expense, or action; provided, however, that the indemnity agreement contained in this Section 2(i)(1) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, expense, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case to a particular such person for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs (i) in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such person, (ii) due to the failure of a Holder to comply with the covenants and agreements contained in this Agreement with respect to the sale of Registrable Securities, and (iii) an untrue statement or omission in any prospectus that is corrected in any subsequent prospectus, or supplement or amendment thereto, that was delivered to such Holder prior to the pertinent sale or sales by such Holder and not delivered by such Holder to the individual or entity to which it made such sale(s) prior to such sale(s).

 

(2)                                 To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act, any underwriter, any other Holder selling securities in such registration statement, any of such other Holder’s partners, officers, or directors, and any person who controls any such other Holder or underwriter within the meaning of the 1933 Act or the 1934 Act, against any losses, claims, damages, liabilities, or expenses (joint or several) to which any of the foregoing persons may become subject, under the 1933 Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation by such Holder, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder and stated by such Holder to be expressly for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this Section 2(i)(2), in connection with investigating or defending any such loss, claim, damage, liability, expense, or action if determined by final judgment (not subject to appeal) of a court of competent jurisdiction that there was such a Violation; provided, however, that the indemnity agreement contained in this Section 2(i)(2) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the prior consent of such Holder, which consent shall not be unreasonably withheld, nor shall a Holder be liable in any such case to a particular such person for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which (i) occurs due to the failure of the Company to comply with the covenants and

 

12

 

agreements contained in this Agreement with respect to the sale of Registrable Securities or (ii) arises from an untrue statement or omission in any prospectus that is corrected in any subsequent prospectus, or supplement or amendment thereto, that was delivered to the Company prior to the pertinent sale or sales by for which the Violation occurred; provided further, that, in no event shall any Holder be liable for indemnity under this Section 2(i)(2) or otherwise in an amount that exceeds the net proceeds from the offering received by such Holder.

 

(3)                                 Promptly after receipt by an indemnified party under this Section 2(i) of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2(i), deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties. After notice from the indemnifying party to any indemnified party(s) of the indemnifying party’s election to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party(s) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would, in the opinion of counsel to the indemnified party, be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding; provided, further, that the indemnifying party shall not be obligated to assume the expenses of more than one counsel to represent all indemnified parties. If any indemnified party is entitled to such separate counsel, such counsel shall be required to cooperate with other counsel representing the indemnifying parties in such action if any indemnifying party is required to pay or reimburse the costs of such separate counsel. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2(i), but the failure so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2(i).

 

If the indemnification provided for in this Section 2(i) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages, liabilities, or expenses referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage, liability, or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the Violation(s) that resulted in such loss, claim, damage liability, or expense, as well as any other relevant equitable considerations. The relative

 

13

 

fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that in no event shall any contribution by a Holder hereunder exceed the proceeds from the offering received by such Holder.

 

(4)                                 The obligations of the Company and Holders under this Section 2(i) shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 2, and otherwise. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. The rights to indemnification and contribution in this Section 2(i) shall be in addition to and not in lieu of any other rights arising under applicable law.

 

(j)                                    Rule 144; Reports Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the 1933 Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public, the Company agrees to:

 

(1)                                 make and keep public information available, as those terms are understood and defined in Rule 144, at all times after ninety (90) days after such effective date;

 

(2)                                 take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the registration statement filed by the Company for its IPO is declared effective, subject to the rules and regulations applying to the use of a Form S-3;

 

(3)                                 file with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the 1934 Act; and

 

(4)                                 furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 under the 1933 Act (at any time after ninety (90) days following the effective date of the first registration statement filed by the Company), the 1933 Act and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at

 

14

 

any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

 

(k)                                 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned by a Holder to a transferee or assignee who acquires all or any part of a Holder’s Registrable Securities (including through holding any Common Stock Equivalents); provided the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if immediately following such transfer the further public disposition of such securities by the transferee or assignee is restricted under the 1933 Act.

 

(l)                                    No Limitation on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall have the right, without any consent or approval of, or notice to, the Holders, to enter into any agreement with any holder or prospective holder of any securities of the Company (i) which would allow such holder or prospective holder to include such securities in any registration filed under Sections 2(a), 2(b) or 2(c) hereof, or (ii) which would restrict the right of the Holders to exercise their rights under Section 2(b) with respect to any registration that the Company effects for any such holder.

 

(m)                              Mergers, Etc. The Company shall not, directly or indirectly, enter into any merger, consolidation or reorganization in which the Company shall not be the surviving corporation unless the proposed surviving corporation shall, prior to such merger, consolidation or reorganization, agree in writing to assume the obligations of the Company under this Section 2, and for that purpose references hereunder to Registrable Securities shall be deemed to be references to the securities which the Holders would be entitled to receive in exchange for Registrable Securities under any such merger, consolidation or reorganization; provided, however, that the provisions of this Section 2(m) shall not apply in the event of any merger, consolidation, or reorganization in which the Company is not the surviving corporation if all stockholders are entitled to receive in exchange for their Registrable Securities consideration consisting solely of (i) cash, (ii) securities of the acquiring corporation which may be immediately sold to the public without further registration under the 1933 Act, and/or (iii) securities of the acquiring corporation which the acquiring corporation has agreed to register within ninety (90) days after completion of the transaction for resale to the public pursuant to the 1933 Act on terms comparable to this Section 2.

 

3.                                      Miscellaneous Provisions.

 

(a)                                 All Shares Held by Holders. The terms and conditions of this Agreement govern all shares of Common Stock and shares of Common Stock issuable upon conversion or exercise of any Common Stock Equivalent held by any

 

15

 

Holder at the time it becomes a party to this Agreement and all such shares of Common Stock acquired, or issuable in respect of Common Stock Equivalents acquired, by such Holder subsequent to the date such Holder becomes a party to this Agreement and before the Company’s IPO, except to the extent the rights of the holder of such shares to registration under the 1933 Act are expressly governed by a separate agreement. A person who acquires beneficial ownership of Registrable Securities from a Holder and who becomes a party to this Agreement in accordance with Section 2(k) shall thereby become a Holder for purposes of this Agreement.

 

(b)                                 Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted transferees and permitted assigns of the parties.

 

(c)                                  Governing Law. This Agreement shall be governed by and construed under the internal laws of the State of New York as applied to agreements among residents of the State of New York entered into and to be performed entirely within the State of New York, without reference to principles of conflict of laws or choice of laws.

 

(d)                                 Counterparts. This Agreement may be executed in counterparts and by the parties hereto on separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

 

(e)                                  Headings. The headings and captions used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. All references in this Agreement to sections, paragraphs, exhibits and schedules shall, unless otherwise provided, refer to sections and paragraphs hereof and exhibits and schedules attached hereto, all of which are incorporated herein by this reference.

 

(f)                                    Stock Splits, etc. All share numbers used in this Agreement are subject to adjustment in the case of any stock split, reverse stock split, combination or similar events.

 

(g)                                 Notices. Unless otherwise provided, any notice required or permitted under this Agreement shall be given in writing and shall be deemed effectively given on the earliest of (i) when received, (ii) upon personal delivery to the party to be notified, (iii) upon delivery via facsimile so long as confirmation of receipt is received from the receiving facsimile machine, (iv) one day after being deposited with an overnight courier service, (v) three days after deposit with the United States Postal Service, by certified mail, postage prepaid and addressed to the party to be notified at the address set forth on the signature page of this Agreement, or (vi) if delivered by e-mail message, at the time at which confirmation of receipt is generated by the recipient opening the e-mail communication and creating a record of receipt of the transmission, or at such other address as such party may designate by ten (10) days advance notice to all other parties.

 

(h)                                 Amendments and Waivers. Any term of this Agreement may

 

16

 

be amended, the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) and any persons may be added as parties hereto, only by an instrument in writing signed by (i) the Company and (ii) Holders who hold a majority in interest of the Registrable Securities held by all Holders. Notwithstanding the foregoing, the Company and the Holders agree that this Agreement shall be automatically amended without further action by the Company or any Holders to add as additional parties any transferee of registration rights as contemplated by Section 2(k) which transferee agrees to be bound by the terms of this Agreement as a Holder. Any such amendments or waivers will be binding on all parties hereto.

 

(i)                                    Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, such provision(s) shall be excluded from this Agreement and the balance of the Agreement shall be interpreted as if such provision(s) were so excluded and shall be enforceable in accordance with its terms to the maximum extent possible.

 

(j)                                    Entire Agreement. This Agreement, together with all exhibits and schedules hereto, constitutes the entire understanding and agreement of the parties with respect to the subject matter hereof and supersedes all prior negotiations, correspondence, agreements, understandings, duties or obligations among the parties with respect to the subject matter hereof.

 

(k)                                 Further Assurances. From and after the date of this Agreement, upon the request of a party, the other parties shall execute and deliver such instruments, documents or other writings as may be reasonably necessary or desirable to confirm and carry out and to effectuate fully the intent and purposes of this Agreement.

Initial Investor agrees that it will not and it will use its reasonable commercial efforts to cause each of its Affiliates and their respective Associates not to, directly or indirectly, alone or in concert with others, pursue further in any manner the acquisition of Control of Kolltan or a possible Change in Control other than by communications with the Permitted Individuals that are otherwise permissible pursuant to this Section 4.2(a), unless (x) the Initial Investor shall first have obtained Kolltan Approval or (y) the Permitted Individuals fail to provide any such written request or proposal to the Board of Directors and notify the Initial Investor that they have done so within 7 business days of receipt thereof.  In addition, following submission of any such private, non-public request or proposal in accordance with this Section 4.2(a), the Initial Investor agrees that it shall nonetheless remain subject to the applicable provisions of Section 4.1.

 

(b)                                 Notwithstanding anything to the contrary contained in this Agreement, the Initial Investor shall be permitted to submit, from time to time following the date of this Agreement, one or more private, non-public requests to amend or waive this Agreement or proposals to acquire Kolltan Securities or assets or enter into a licensing or collaboration agreement with Kolltan, in each case, that does not otherwise involve the acquisition of Control of Kolltan or a possible Change in Control.  Following submission of any such private, non-public request or proposal in accordance with this Section 4.2(b), the Initial Investor agrees that it shall nonetheless remain subject to the applicable provisions of Section 4.1.

 

(c)                                  The obligations of and restrictions applicable to Investor under Section 2.1, Section 4.1 and Section 4.2 shall be suspended in the event that and during the period after (i) Kolltan publicly announces that it has entered into an agreement with any person or group which provides for a transaction constituting a Change in Control, (ii) the Board of Directors

 

10

 

 

recommends that holders of Kolltan Securities tender their Kolltan Securities in connection with or vote in favor of a transaction constituting a Change in Control, (iii) any person or group publicly announces an intention to commence a tender offer for more than 50% of the Voting Power of Kolltan or (iv) the Board of Directors determines to initiate an auction process related to a transaction that, if consummated, would result in a Change in Control, in each case, until such time, if applicable, that such transaction is consummated, such agreement is terminated or such tender offer, or intention to commence such tender offer, is withdrawn or terminated or expires in accordance with its terms.

 

4.3                               Election of Directors.  In furtherance and not in limitation of the foregoing, the Investor agrees to, and it will cause each of its Affiliates and their respective Associates to, abstain from voting any shares of Series C Preferred Stock that it Beneficially Owns with respect to the election of any member of the Board of Directors.

 

ARTICLE V

 

MISCELLANEOUS

 

5.1                               Suspension; Election to Accept Other Terms.

 

(a)                                 The provisions of this Agreement shall be suspended if the Investor Securities cease to represent 7.5% or more of the Voting Power of the outstanding Kolltan Securities; provided, however, if at any time thereafter and prior to termination of this Agreement pursuant to Section 5.2 the Investor and its Affiliates and their respective Associates or any Group of which any of them is a member shall once again Beneficially Own Kolltan Securities that represent 7.5% or more of the Voting Power of the outstanding Kolltan Securities, then the provisions of this Agreement shall be reinstated.

 

(b)                                 If at any time after the date of this Agreement while this Agreement shall be in effect, Kolltan agrees to an investment in Kolltan by a company, other than [**] (or its Affiliates or their respective Associates), whose principal business is research, development, sales, or marketing of pharmaceutical products (an “Other Pharmaceutical Company”), pursuant to the terms of which investment Kolltan will issue Kolltan Securities to such Other Pharmaceutical Company in an amount such that such Other Pharmaceutical Company will Beneficially Own Kolltan Securities which entitle such Other Pharmaceutical Company to Voting Power of Kolltan that is equal to or greater than both (1) the Voting Power of the Investor Securities at the time of such investment and (2) 15.3% of the total Voting Power of Kolltan, then Kolltan shall by notice to the Initial Investor inform the Initial Investor of the terms of the standstill and other restrictions, if any, applicable to the Other Pharmaceutical Company that are of the same nature as those in Articles II and IV and Sections 5.1 and 5.2 of this Agreement (the “Other Pharmaceutical Company Standstill Terms”).  The Initial Investor may elect, by notice given to Kolltan within 30 days after the Initial Investor receives such notice of the Other Pharmaceutical Company Standstill Terms, to be governed by the Other Pharmaceutical Company Standstill Terms in lieu of the pertinent terms of this Agreement.  Time shall be of the essence in the Initial Investor giving such notice.  If the Initial Investor so elects and the Other

 

11

 

Pharmaceutical Company completes such investment in Kolltan, then promptly thereafter, the parties hereto shall enter into a written agreement amending this Agreement to implement the pertinent Other Pharmaceutical Company Standstill Terms for the Investor, as so elected by the Initial Investor, and the pertinent provisions of this Agreement shall be so amended once the parties enter into such agreement.  The provisions of this Agreement shall remain in effect until the parties execute and deliver, one to the other, such other agreement that sets forth the Other Pharmaceutical Company Standstill Terms.  If the Initial Investor shall not make a timely election, then the terms of this Agreement shall remain in effect.

 

(c)                                  If at any time after the date of this Agreement while this Agreement shall be in effect, it becomes evident to Kolltan both that (1) the Voting Power of the Investor Securities shall have become equal to or less than the Voting Power of Kolltan Securities Beneficially Owned by an Other Pharmaceutical Company and (2) the Voting Power of Kolltan Securities Beneficially Owned by an Other Pharmaceutical Company is equal to or greater than 15.3% of the total Voting Power of Kolltan, then, promptly after learning such information, Kolltan shall by notice to the Initial Investor inform the Initial Investor of the terms of the Other Pharmaceutical Company Standstill Terms.  The Initial Investor may elect, by notice given to Kolltan within five Business Days after the Initial Investor receives such notice of the Other Pharmaceutical Company Standstill Terms, to be governed by the Other Pharmaceutical Company Standstill Terms in lieu of the pertinent terms of this Agreement.  Time shall be of the essence in the Initial Investor giving such notice.  If the Initial Investor so elects, then promptly thereafter, the parties hereto shall enter into a written agreement amending this Agreement to implement the pertinent Other Pharmaceutical Company Standstill Terms for the Investor, as so elected by the Initial Investor, and the pertinent provisions of this Agreement shall be so amended once the parties enter into such agreement.  The provisions of this Agreement shall remain in effect until the parties execute and deliver, one to the other, such other agreement that sets forth the Other Pharmaceutical Company Standstill Terms.  If the Initial Investor shall not make a timely election, than the terms of this Agreement shall remain in effect.

 

5.2                               Termination.  The provisions of this Agreement shall terminate upon the earliest to occur of:

 

(a)                                 Change in Control of Kolltan or any sale, exchange, or other Transfer by stockholders of more than 50% of the outstanding Voting Power of Kolltan in a single transaction in compliance with Section 4 of the Investor Rights Agreement; or

 

(b)                                 written release of the Investor from this Agreement by Kolltan Approval.

 

5.3                               Notices.  All notices, consents, waivers and other communications required or permitted to be given by any provision of this Agreement shall be in writing to the addresses below and shall be effective (a) if sent by certified mail, postage prepaid, return receipt requested, three Business Days after being deposited for mailing with the facilities of the United States Postal Service, (b) if sent by hand, upon receipt, (c) if sent by a reputable nationwide overnight courier, charges prepaid, one Business Day after being sent or such later date as the records of such courier service show delivery to have been made to such address, or (d) if sent by facsimile transmission, with electronic confirmation of receipt, upon such confirmation if such

5.4                               Assignment.  No party will assign this Agreement or any rights, interests or obligations hereunder, or delegate performance of any of its obligations hereunder, without the prior written consent of each other party.  Notwithstanding the foregoing no consent of Kolltan shall be required for the Initial Investor’s assignment of this Agreement (1) by operation of law in a merger or consolidation of the Initial Investor into or with another Person or (2) to a Person to whom the Initial Investor transfers all or substantially all of its assets and business so long as in any such case in the preceding clause (1) or (2) prior to the effective time of such merger or consolidation the surviving or resulting Person, or prior to such transfer of assets and business such transferee, as the case may be, shall have executed and delivered an instrument, in form, scope, and substance reasonably acceptable to Kolltan expressly assuming the obligations of the Initial Investor hereunder and agreeing to be bound hereby.

 

5.5                               Entire Agreement.  This Agreement embodies the entire agreement and understanding of the parties with respect to the subject matter contained herein and supersedes all prior agreements and understandings between the parties with respect to such subject matter;

 

13

 

provided, however, that nothing in this Agreement shall abrogate, supersede, or release the Investor from any of its obligations under the Subscription Agreement, the Investor Rights Agreement any other written agreement between the parties executed contemporaneously with this Agreement.

 

5.6                               Waiver, Amendment, etc.  This Agreement may not be amended or supplemented, and no waivers of or consents to departures from the provisions hereof shall be effective, unless set forth in a writing signed by, and delivered to, all the parties.  No failure or delay of any party in exercising any power or right under this Agreement will operate as a waiver thereof, nor will any single or partial exercise of any right or power, or any abandonment or discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power.

 

5.7                               Binding Agreement; No Third Party Beneficiaries.  This Agreement will be binding upon and inure to the benefit of the parties and their successors and permitted assigns.  Nothing expressed or implied herein is intended or will be construed to confer upon or to give to any third party any rights or remedies by virtue hereof.

 

5.8                               Governing Law; Dispute Resolution; Equitable Relief.

 

(a)                                 This Agreement shall be governed by and construed in accordance with the laws of the State of New York (regardless of the laws that might otherwise govern under applicable principles of conflicts of law).

 

(b)                                 In the event of a dispute arising under this Agreement between the parties, either party shall have the right to refer such dispute to the parties’ respective Chief Executive Officers, whereupon such Chief Executive Officers shall make a good faith attempt to resolve such dispute.

 

(c)                                  Each party irrevocably consents and agrees that any legal action, suit or proceeding against it with respect to its obligations or liabilities under or arising out of or in connection with this Agreement shall be brought only in the United States District Court for the Southern District of New York or, in the event (but only in the event) such court does not have subject matter jurisdiction over such action, suit or processing, in the courts of the State of New York sitting in the County of New York, and each party hereby irrevocably accepts and submits to the jurisdiction of each of the aforesaid courts in person, with respect to any such action, suit or proceeding (including claims for interim relief, counterclaims, actions with multiple defendants and actions in which such party is implead).  Each party irrevocably and unconditionally waives any right that it may have to a jury trial in any legal action, suit or processing with respect to, or arising out of or in connection with this Agreement.

 

(d)                                 The Investor agrees, and shall cause each of its Affiliates and their respective Associates to agree, that money damages would not be a sufficient remedy for any breach of this Agreement by it, and that in addition to all other remedies Kolltan may have, Kolltan shall be entitled to specific performance and to injunctive or other equitable relief as a remedy for any such breach.  The Investor agrees, and shall cause each of its Affiliates and their respective Associates to agree, not to oppose the granting of such relief in the event a court

 

14

 

determines that such breach has occurred, and agrees to waive any requirement for the securing or posting of any bond in connection with such remedy.  Notwithstanding Section 5.8(b) hereof,  Kolltan shall have the right to seek injunctive or other equitable relief as a remedy with respect to a breach of this Agreement simultaneously with referring such dispute to the parties’ respective Chief Executive Officers or any attempt by the Chief Executive Officers to resolve such dispute.

 

5.9                               Severability.  The invalidity or unenforceability of any provision hereof in any jurisdiction will not affect the validity or enforceability of the remainder hereof in that jurisdiction or the validity or enforceability of this Agreement, including that provision, in any other jurisdiction.  To the extent permitted by applicable law, each party waives any provision of applicable law that renders any provision hereof prohibited or unenforceable in any respect.  If any provision of this Agreement is held to be unenforceable for any reason, it shall be adjusted rather than voided, if possible, in order to achieve the intent of the parties to the extent possible.

 

5.10                        Counterparts.  This Agreement may be executed in one or more counterparts and by the parties on separate counterparts, each of which when so executed and delivered will be deemed an original but all of which will constitute one and the same Agreement.

 

5.11                        Information.  The Investor will from time to time, upon written request of Kolltan, provide such information as Kolltan shall reasonably request for purposes of confirming compliance by the Investor and its Affiliates and their respective Associates with the terms of this Agreement or the Confidentiality Agreement, which information the Investor has or can obtain without unreasonable effort or expense; provided, however, that nothing herein shall obligate the Investor and its Affiliates and their respective Associates to provide information covered by attorney-client privilege or the provision of which would breach or violate a written confidentiality obligation of the Investor or its Affiliates and their respective Associates, in which cases written certification by the Investor Representative confirming compliance in relevant part shall be acceptable.  Kolltan shall, in accordance with the Confidentiality Agreement, hold in confidence and not use or disclose any confidential information provided to or learned by it in connection with its rights under this Section.

 

5.12                        Remedies.  In addition to any other remedies which may be available to Kolltan (including any remedies which Kolltan may have at law or in equity):

 

(a)                                 If the Investor breaches Article II, Section 4.1(a) or Section 4.1(b)(i) of this Agreement in any material respect, then (x) unless and until such breach is cured in all material respects or (y) unless such breach otherwise constitutes an Inadvertent Breach determined in accordance with Section 5.12(d), the Investor Securities shall not be entitled to Vote with respect to any matter or proposal arising from, related to or involving such breach without first obtaining Kolltan Approval, and no such purported Vote of the Investor Securities on such matter shall be effective or shall be counted.  Except as set forth in the immediately preceding sentence and in Section 4.3, nothing in this Agreement shall in any way diminish or limit the Initial Investor’s right to Vote the Investor Securities in any way that it desires, including on any amendment or waiver of any provision of any agreement between Kolltan and the Initial Investor.

 

15

 

(b)                                 The Investor agrees that Kolltan shall have no obligation to recognize, to reflect in its registers of owners of securities, or otherwise to honor Transfers of Kolltan Securities or other Equity Interests in Kolltan to the Investor or any of its Affiliates or any of their respective Associates which Transfers would cause the Investor and its Affiliates and their respective Associates to Beneficially Own Kolltan Securities or other Equity Interests in Kolltan in violation of this Agreement, any such Transfers shall be void and of no effect, and Kolltan shall be entitled to instruct any transfer agent or agents for such Kolltan Securities or other Equity Interests in Kolltan to refuse to recognize, to reflect in its registers of owners of securities, and to honor such Transfers.

 

(c)                                  In case at the time when the Investor shall have the right to purchase Pre- emptive Right Securities as permitted by clause (iii) of the proviso to Section 2.1 there shall be a dispute as to whether or not the Investor is in breach of a material term of this Agreement, any exercise of such right to purchase Pre-emptive Right Securities and the purchase thereof by the Investor shall be contingent on resolution of such dispute in favor of the Investor.  Such exercise and purchase shall be made in a manner and on express written terms such that such purchase shall be rescinded in case such dispute is resolved in favor of Kolltan rather than in favor of the Investor.

 

(d)                                 Notwithstanding any other provision of this Agreement to the contrary, a breach of a material term of this Agreement shall not result in the loss of (x) the Investor’s right to purchase additional Pre-emptive Right Securities pursuant to clause (iii) of the proviso to Section 2.1, (y) the Investor’s right to participate in certain transactions as provided in Section 4.1(a) or (z) the right to Vote the Investor Securities as provided in Section 5.12(a) if such breach shall constitute an “Inadvertent Breach,” as determined under this Section 5.12(d).  A breach shall be considered an Inadvertent Breach if it meets all of the following criteria:

 

(1)                                 the breach shall have been inadvertent and not by reason of negligent or willful conduct in breaching this Agreement and not done with reckless disregard of the obligations under this Agreement, knowingly in breach of this Agreement, or with intent to breach this Agreement, as shown by its nature and context;

 

(2)                                 the breach shall involve an oral statement or email message relating to an informal proposal or an informal suggestion or a request or discussion by the Initial Investor, the Investor Representative, or the Observer and,

 

(A)                               if the breach is made by oral statement it shall have been (i) addressed to any one or more of the Chairman of the Board, the Chief Executive Officer or the President of Kolltan or Schlessinger or Altschul, and no one else who is a director, officer or employee of, or consultant to, Kolltan or who is a Beneficial Owner of any Kolltan Securities, or (ii) made by the Observer at a meeting of the Board of Directors, or a portion of any such meeting, that the Observer is entitled to attend, and in any such case in the immediately preceding clause (i) or (ii) shall be a matter that the individual causing such breach believed at the time of making the statement to be in, or not opposed to, the best interests of Kolltan; or

 

(B)                               if the breach is contained in an email message, it shall have been addressed to any one or more of the Chairman of the Board, the Chief Executive Officer, or

 

16

 

the President of Kolltan or Schlessinger or Altschul, and no one else who is a director, officer, or employee of, or consultant to, Kolltan or who is a Beneficial Owner of any Kolltan Securities; and

 

(3)                                 by reason of such breach Kolltan shall not have been required, based on the advice of its legal counsel, to have made public disclosure of the conduct or contents of the statements constituting such breach.

 

For purposes of determining whether a breach is an Inadvertent Breach, the Investor and its Affiliates and their respective Associates shall be deemed to know the terms of this Agreement.  If the Initial Investor learns that a breach of this Agreement by the Investor or any of its Affiliates or any of their respective Associates may have occurred, the Initial Investor shall notify Kolltan of such fact as promptly as practical, but in no event later than three Business Days after the Initial Investor learns that an Inadvertent Breach may have occurred.  Such notice shall be accompanied by such information about the nature and circumstances of such breach as the Initial Investor may have or may obtain without unreasonable effort or expense.  The Initial Investor shall provide such other information or explanation concerning such possible breach as Kolltan may reasonably request, promptly, but in no event later than three Business Days after such request or such longer period as Kolltan may permit.

 

5.13                        Legend.  In addition to the restrictive legends provided in the Subscription Agreement and the Investor Rights Agreement, the Investor agrees, and shall cause its Affiliates and the respective Associates of the Investor and its Affiliates to agree, to the imprinting of a legend on any of the certificates representing any Investor Securities in the following form:

 

THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A STANDSTILL AGREEMENT, A COPY OF WHICH IS AVAILABLE FOR INSPECTION AT THE CORPORATION’S OFFICE.  THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON SALE, TRANSFER AND VOTING.

 

Kolltan may impose stop-transfer instructions and restrictions relating in this Agreement in its and any transfer agent’s records.

 

5.14                        Effectiveness.  This Agreement shall become effective on the Closing Date.
