ARTICLE 2
 REGISTRATION RIGHTS 

        Section 2.01.    Demand Registration.    (a) At any time on or after the date hereof, if the Company
shall receive a written request by a Holder (a "Requesting Holder") that the Company effect a 

2

 

Demand
Registration of all or a portion of such Requesting Holder's Registrable Securities, and specifying the intended method of disposition thereof, then the Company shall promptly give written
notice of such requested Demand Registration at least 20 days prior to the anticipated filing date of the registration statement relating to such Demand Registration to each other Holder (the
"Other Holders") and thereupon will use its best efforts to effect, as expeditiously as possible, the registration under the Securities Act of: 

	(i)
	the
Registrable Securities which the Company has been so requested to register by the Requesting Holder; and

	(ii)
	all
other Registrable Securities which the Other Holders have requested the Company to register by written request received by the Company within 10 days after
the receipt by the Other Holders of the written notice given by the Company, 

all
to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered; provided
that, subject to Section 2.01(d) hereof, the Company shall not be obligated to effect more than two Demand Registrations for the Holders;  provided further that the Company
shall not be obligated to effect a Demand Registration for any Holder unless the aggregate proceeds expected to be
received from the sale of the Registrable Securities to be included in such Demand Registration, in the reasonable opinion of the Board, equals or exceeds $50,000,000; and
provided further that the Company shall not, in any event, be required to effect more than one Demand Registration for all Holders pursuant to this Section 2.01(a)
within any twelve month period. In addition, the Company shall have the right to preempt any Demand Registration (including, for the avoidance of doubt, any Shelf Takedown) with a primary registration
by delivering written notice (within 10 days after the Company has received from the Selling Stockholder a request for such Demand Registration) of such intention to the Selling Stockholder
indicating that the Company has identified a specific business need and use for the proceeds of the sale of such securities and the Company shall use all commercially reasonable efforts to effect a
primary registration within 120 days of such notice. In the ensuing primary registration, the Holders will have such incidental registration rights as are set forth in Section 2.02
hereof. Upon the Company's preemption of a requested Demand Registration, such requested registration will not count as a Demand Registration. The Company shall not be entitled to exercise this right
of preemption more than one time in any 12-month period. Notwithstanding the foregoing, in connection with any Demand Registration, the Holders shall not be permitted to request that a
Shelf Registration Statement be filed. 

        (b)   The
Selling Stockholder requesting a registration under this Section (including, for the avoidance of doubt, any Shelf Takedown) may, at any time prior to the effective
date of the registration statement relating to such registration (or, at any time prior to the date of any Shelf Takedown if a Shelf Registration Statement has been filed and declared effective),
revoke such request, without liability to such Selling Stockholder, by providing a written notice to the Company revoking such request, in which case such request, so revoked, shall not be considered
a Demand Registration. 

        (c)   Any
Holder participating in any Demand Registration will pay all Holder Registration Expenses in connection with such Demand Registration that are allocable to the
shares sold by that Holder, and except in the case where a Selling Stockholder's revocation of a Demand Registration request arises out of the fault of the Company, the Participating Holders will pay
all Company Registration Expenses in connection with such Demand Registration, proportionally in accordance with their Registrable Securities included in such Demand Registration. 

        (d)   A
Demand Registration requested pursuant to this Section shall not be deemed to have been effected (i) unless the registration statement relating thereto
(A) has become effective under the Securities Act and (B) has remained effective until such time as the Registrable Securities included in such registration have actually been sold
thereunder; provided that if after any registration statement requested pursuant to this Section becomes effective such registration statement is
interfered with by 

3

 

any
stop order, injunction or other order or requirement of the SEC or other governmental agency or court, such a Demand Registration shall not be deemed to have been effected. 

        (e)   If
the managing underwriter of an offering advises the Company that, in its view, the number of Registrable Securities requested to be included in a registration
effected under this Section 2.01 (including any securities which the Company proposes to be included which are not Registrable Securities) exceeds the largest number of securities which can be
sold without having an adverse effect on such offering, including the price at which such securities can be sold (the "Maximum Offering Size"), the
Company will include in such registration, in the priority listed below, up to the Maximum Offering Size: 

        (A)  first,
all Registrable Securities requested to be included in such registration by the Requesting Holder and the Other Holders (allocated, if necessary for the offering
not to exceed the Maximum Offering Size, pro rata among such Requesting Holder and such Other Holders on the basis of the relative number of shares of Registrable Securities requested to be included
in such registration); and 

        (B)  second,
any securities proposed to be registered by the Company. 

        (f)    If
the Company is eligible to file with the SEC a Shelf Registration Statement, the Company may, in its sole discretion, file with the SEC a Shelf Registration Statement
with respect to Registrable Securities then outstanding. After a Shelf Registration Statement has been filed, for as long as the Company is eligible to use such Shelf Registration Statement, the
Holders may only exercise any Demand Registrations remaining under Section 2.01(a) to effect the sale of Registrable Securities pursuant to a Shelf Takedown (subject to the other limitations
applicable to Demand Registrations by Holders and other Selling Stockholders contained herein). 

        (g)   In
the event another stockholder of the Company shall have exercised any right to require the Company to register its shares of Class A Common Stock for sale
under the Securities Act, then no Holder shall be permitted to request a Demand Registration until the registration requested by such other stockholder shall have been completed and any
hold-back period contemplated by Section 2.03 shall have expired. 

        Section 2.02.    Incidental Registration.    (a) If the Company proposes to register Class A
Common Stock under the Securities Act (other than a registration (A) on Form S-8 or S-4 or any successor or similar forms, (B) relating to equity
securities issuable upon exercise of employee stock options or in connection with any employee benefit or similar plan of the Company, (C) for its own account pursuant to Rule 415, or
(D) in connection with a direct or indirect acquisition by the Company of another company), it will each such time, subject to the provisions of Section 2.02(b), give prompt written
notice at least 30 days prior to the anticipated filing date of the registration statement relating to such registration to the Holders, which notice shall set forth the Holders' rights under
this Section 2.02 and shall offer the Holders the opportunity to include in such registration statement such number of Registrable Securities as are proposed to be registered as each such
Holder may request (an "Incidental Registration"). Upon the written request of any Holder made within 10 days after the receipt of notice from
the Company (which request shall specify the number of Registrable Securities intended to be disposed of in such registration by the Holder), the Company will use its best efforts to effect the
registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by such Holders, to the extent required to permit the disposition of the
Registrable Securities so to be registered; provided that (I) if the registration statement the Company proposes to file relates to an
underwritten offering, all Holders requesting to be included in the Company's registration must sell their Registrable Securities to the underwriters selected as provided in Section 2.04(f) on
the same terms and conditions as apply to the Company, and (II) if, at any time after giving written notice of its intention to register any stock pursuant to this Section 2.02(a) and
prior to the effective date of the registration statement filed in connection with such registration, the 

4

 

Company
shall determine for any reason not to register such securities, the Company shall give written notice to all such Holders and, thereupon, shall be relieved of its obligation to register any
Registrable Securities in connection with such registration. No registration effected under this Section 2.02 shall relieve the Company of its obligations to effect Demand Registrations to the
extent required by Section 2.01. The Company will pay all Company Registration Expenses, and the participating Holders will pay all Holder Registration Expenses, in connection with each
registration of Registrable Securities requested pursuant to this Section 2.02. 

        (b)   If
the managing underwriter of an offering advises the Company that, in its view, the number of shares of Class A Common Stock that the Company and Participating
Holders intend to include in a registration effected under this Section 2.02 exceeds the Maximum Offering Size, the Company will include in such registration, in the following priority, up to
the Maximum Offering Size: 

	(i)
	first,
so much of the securities proposed to be registered by the Company as would not cause the offering to exceed the Maximum Offering Size; and

	(ii)
	second,
all Registrable Securities requested to be included in such registration statement by Participating Holders (allocated, if necessary for the offering not to
exceed the Maximum Offering Size, pro rata among the Participating Holders on the basis of the relative number of shares of Registrable Securities requested by each of them to be so included). 

        Section 2.03.    Holdback Agreements.    If the underwriters of a proposed underwritten offering of
Class A Common Stock effected under this Agreement or otherwise conducted by the Company request that the Holders do so, each Holder agrees not to offer, sell, contract to sell, pledge, grant
any option to purchase, make any short sale or otherwise dispose of any Registrable Securities (other than as part of a registration effected under this Agreement) beginning on the date of any
preliminary prospectus used in connection with the underwritten offering (or, if there is no preliminary prospectus, the date of the final prospectus or prospectus supplement), through the period
after the pricing date of such offering equal to the lesser of (i) such period of time as agreed between the managing underwriter of such offering and the Company and
(ii) 120 days. 

        Section 2.04.    Registration Procedures.    Whenever Holders entitled to do so request that any Registrable
Securities be registered pursuant to Section 2.01 or 2.02, the Company will, subject to the provisions of such Sections and the other limitations set forth herein, use its best efforts
to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable, and in connection with any such request: 

        (a)   The
Company will as expeditiously as possible prepare and file with the SEC a registration statement on any form for which the Company then qualifies or which counsel
for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution
thereof, and use its best efforts to cause such filed registration statement to become and remain effective for such period as may be reasonably necessary to effect the sale of such securities, or, in
the case of any Shelf Takedown, the Company shall as expeditiously as possible prepare and file with the SEC a prospectus supplement for such Shelf Takedown; provided
that if the Company shall furnish to Participating Holders a certificate signed by the Company's Chairman or President stating that in the good faith judgment of the Company's
Board it would be detrimental to the Company or its stockholders for such a registration statement to be filed or become effective or for such prospectus supplement to be filed as expeditiously as
possible, the Company may postpone the filing or effectiveness of a registration statement or prospectus supplement for a period of no more than 120 days (provided
that the Company may not defer such filing or effectiveness pursuant to this clause more than once in any 12-month period); and provided
further that if (i) the effective date of any registration statement filed pursuant to a Demand Registration or the filing date of any prospectus supplement would
otherwise be at least 45 calendar days, but fewer than 90 calendar days, after the end of the Company's fiscal year, and (ii) the Securities 

5

 

Act
requires the Company to include audited financials as of the end of such fiscal year, the Company may delay the effectiveness of such registration statement or filing of such prospectus supplement
for such period as is reasonably necessary to include or incorporate therein its audited financial statements for such fiscal year, although the Company will use reasonable efforts to minimize the
length of such delay. 

        (b)   The
Company will, if requested, prior to filing a registration statement or prospectus or any amendment or supplement thereto, furnish to Participating Holders and each
underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed, and thereafter the Company will furnish to such
Holders and underwriters such number of copies of such registration statement, each amendment and supplement thereto (in each case including all exhibits thereto and documents incorporated by
reference therein), the prospectus included in such registration statement (including each preliminary prospectus and each prospectus supplement) and such other documents as such Holders or
underwriters may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holders. 

        (c)   After
the filing of a registration statement in connection with a Demand Registration or an Incidental Registration, the Company will promptly notify each Participating
Holder of any stop order issued or threatened by the SEC and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered. 

        (d)   The
Company will use its best efforts to (i) register or qualify the Registrable Securities covered by such registration statement under the securities or blue
sky laws of such jurisdictions in the United States as any Participating Holder reasonably (in light of such Holder's intended plan of distribution) requests and (ii) cause such Registrable
Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company and, subject to the other
limitations contained herein, do any and all other acts and things that may be reasonably necessary or advisable to enable Participating Holders to consummate the disposition of their Registrable
Securities; provided that the Company will not be required to (A) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph (d), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such
jurisdiction. 

        (e)   The
Company will immediately notify each Participating Holder, at any time when a prospectus or prospectus supplement relating to sales of Registrable Securities by the
Participating holders. relating thereto is required to be delivered under the Securities Act, of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus or
prospectus supplement so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein not misleading and promptly prepare and make available to each Participating Holder any such supplement or
amendment. 

        (f)    The
Company shall have the right to appoint the managing underwriters and any additional investment bankers and managers to be used in connection with a Demand
Registration or an Incidental Registration, provided that in the case of a Demand Registration, the appointment of the lead managing underwriter shall
be subject to the reasonable approval of the Selling Stockholder. Each Participating Holder and the Company will enter into customary agreements (including an underwriting agreement in customary form
containing customary indemnification provisions) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of Registrable Securities pursuant to this
Agreement. 

        (g)   The
Company will make available for inspection by any underwriter participating in any disposition pursuant to a registration statement being filed by the Company
pursuant to this Agreement and any attorney or other professional retained by any such underwriter (collectively, the "Advisors"), 

6

 

all
financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records") as shall be reasonably
necessary to enable them to exercise their due diligence responsibility, and cause the Company's officers, directors and employees to supply all information reasonably requested by any Advisors in
connection with such registration statement. Records that the Company determines, in good faith, to be confidential and that it notifies the Advisors are confidential, shall be provided upon the
execution of confidentiality agreements in the form and substance satisfactory to the Company. 

        (h)   The
Company will furnish to each such underwriter, addressed to such underwriter, (i) an opinion or opinions of counsel to the Company and (ii) a comfort
letter or comfort letters from the Company's independent public accountants, each in customary form and covering such matters of the type customarily covered by opinions or comfort letters, as the
case may be, as the managing underwriter therefor reasonably requests. 

        (i)    The
Company will otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its stockholders, as soon as
reasonably practicable, an earnings statement covering a period of 12 months, beginning within three months after the effective date of the registration statement (determined in accordance with
SEC Rules 159 and 430B and any undertakings required by SEC Regulation S-K), which earnings statement shall satisfy the provisions of Section 11(a) of the Securities
Act. 

        The
Company may require each Participating Holder to promptly furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company
may from time to time reasonably request and such other information as may be legally required in connection with such registration. 

        Each
Participating Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.04(e) such Participating Holder
will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Participating Holder's receipt of the copies of
the supplemented or amended prospectus contemplated by Section 2.04(e) and, if so directed by the Company, such Participating Holder will deliver to the Company, or destroy, all copies, other
than any permanent file copies then in such Participating Holder's possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. 

	(j)
	The
Company will use all commercially reasonable efforts to cause all such Registrable Securities to be listed on each securities exchange or quoted on each inter-dealer quotation
system on which the Class A Common Stock is then listed or quoted. 

        Section 2.05.    Indemnification by the Company.    The Company agrees to indemnify and hold harmless each
Participating Holder, its officers, directors and agents, and each person, if any, who controls such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act from and against any and all losses, claims, damages and liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in or incorporated into any
registration statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary
prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished in writing to the Company by
such Holder or on such Holder's behalf expressly for use therein; provided that with respect to any untrue statement or omission or alleged untrue
statement or omission, the indemnity agreement contained in this paragraph shall not apply to the extent that any such loss, claim, damage, liability or expense results from the fact that a current
copy of the preliminary prospectus or prospectus (as amended or 

7

 

supplemented,
including by any free-writing prospectus) was not sent or given to the person asserting any such loss, claim, damage, liability or expense at or prior to the time of sale of
the Registrable Securities concerned to such person if it is determined that the Company has provided such current copy of such preliminary prospectus or prospectus (as amended or supplemented,
including by any free-writing prospectus) and it was the responsibility of such Holder to provide such person with such current copy of such preliminary prospectus or prospectus (as
amended or supplemented, including by any free-writing prospectus) and such current copy would have cured the defect giving rise to such loss, claim, damage, liability or expense. As a
condition to including Registrable Securities in any registration statement filed in accordance with Article 2 hereof, the Company may require that it shall have received an undertaking
reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by underwriters with respect to similar securities. 

        Section 2.06.    Indemnification by Participating Holders.    Each Participating Holder agrees, severally but
not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each person, if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Holder, but only (i) with respect to information furnished in
writing by such Holder or on such Holder's behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto,
including any free-writing prospectus, or any preliminary prospectus or (ii) to the extent that any loss, claim, damage, liability or expense described in Section 2.05
results from the fact that a current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing prospectus) was not sent or given to the
person asserting any such loss, claim, damage, liability or expense at or prior to the time of sale of the Registrable Securities concerned to such person if it is determined that it was the
responsibility of such Holder to provide such person with such current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing
prospectus) and such current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing prospectus) would have cured the defect giving rise
to such loss, claim, damage, liability or expense. Each such Holder, severally, also agrees to indemnify and hold harmless the underwriters of Registrable Securities
sold by that Holder, their officers and directors and each person who controls such underwriters on substantially the same basis as that of the indemnification of the Company provided in this
Section 2.06. As a condition to including Registrable Securities in any registration statement filed in accordance with Article 2 hereof relating to an underwritten offering, each
Participating Holder may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities. 

        Section 2.07.    Conduct of Indemnification Proceedings.    In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Article 2 such person (an "Indemnified
Party") shall promptly notify the person against whom such indemnity may be sought (the "Indemnifying Party") in writing and the
Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses;  providedthat the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations
hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to
the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the Indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the
reasonable fees 

8

 

and
expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as
they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable
for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify
and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. No Indemnifying Party shall, without the prior
written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have
been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding. 

        Section 2.08.    Contribution.    If the indemnification provided for in this Article 2 is unavailable
to the Indemnified Parties in respect of any losses, claims, damages or liabilities referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (i) as between the Company and the Participating Holders on the one
hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and such Holders on the one hand and the underwriters on the
other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but
also the relative fault of the Company and such Holders on the one hand and of such underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations and (ii) as between the Company on the one hand and each such Holder on the
other, in such proportion as is appropriate to reflect the relative fault of the Company and of each such Holder in connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Company and such Holders on the one hand and such underwriters on the other shall be deemed to be in the same proportion as the total
proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and such Holders bear to the total underwriting discounts and
commissions received by such underwriters, in each case as set forth in the table on the cover page of the prospectus. The relative fault of the Company and such Holders on the one hand and of such
underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company and such Holders or by such underwriters. The relative fault of the Company on the one hand and of each such Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by such party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

        The
Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.08 were determined by pro rata allocation (even if the
underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 2.08, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the 

9

 

public
were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission, and no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Holder were offered to the
public exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. Each such Holder's obligation to contribute pursuant to this Section 2.08 is several in the proportion that the proceeds of the offering received by such Holder bears to the
total proceeds of the offering received by all such Holders and not joint. 

        Section 2.09.    Participation Limitations.    No Person may participate in a Demand Registration or an
Incidental Registration hereunder unless such Person (a) agrees to sell such Person's securities on the basis provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and the provisions of this Agreement in respect of registration rights. 

        Section 2.10.    Other Indemnification.    Indemnification similar to that specified herein (with appropriate
modifications) shall be given by the Company and each Participating Holder with respect to any required registration or other qualification of securities under any federal or state law or regulation
or governmental authority in addition to the Securities Act. 

ARTICLE 3
 RULE 144 

        Section 3.01.    Rule 144.    The Company covenants with the Holders that it will file any reports
required to be filed by it under the Securities Act and the Exchange Act and that it will take such further action as the Holders may reasonably request to the extent required from time to time to
enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144. Upon the request of any Holder, the
Company will deliver to such Holder a written statement as to whether it has complied with such reporting requirements. 

ARTICLE 4
 MISCELLANEOUS 

        Section 4.01.    Entire Agreement.    This Agreement constitutes the entire agreement among the parties hereto
and supersedes the 2005 Agreement and all other prior agreements and understandings, oral and written, among the parties hereto with respect to the subject matter hereof. 

        Section 4.02.    Binding Effect; Benefit.    This Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, successors, assigns and Permitted Transferees. Nothing in this Agreement, expressed or implied, shall confer on any Person other than the parties hereto,
and their respective heirs, successors, assigns and Permitted Transferees, any rights, remedies, obligations or liabilities under or by reason of this Agreement. 

        Section 4.03.    Assignability.    Other than to Permitted Transferees, no party may assign, delegate or
otherwise transfer any of its rights or obligations under this Agreement, directly or indirectly, whether by operation of law or otherwise, without the written consent of the Company, and any
attempted assignment contrary to the terms hereof shall be null and void. Neither this Agreement nor any provision hereof is intended to confer upon any Person other than the parties hereto and their
Permitted Transferees any rights or remedies hereunder. 

10

 

        Prior
to any transfer of rights to a Permitted Transferee, the transferring Holder shall provide the Company with notice of the Permitted Transferee's name and address and the number of
Registrable Securities with respect to which such rights are being transferred. The Permitted Transferee shall assume the obligations of a Holder under this Agreement in a written instrument delivered
to the Company. If, in connection with such transfer, a Holder has transferred all of its Registrable Securities to such Permitted Transferee, then the transferring Holder shall be released from all
liability under this Agreement other than, and solely with regard to, the provisions of Sections 2.06, 2.08 and 2.10 of this Agreement in connection with any Demand Registration or Incidental
Registration in which such Holder was a Participating Holder and any provision hereof obligating such Holder to pay or reimburse the Company for any Company Registration Expenses incurred prior to
such transfer. 

        Section 4.04.    Amendment; Waiver.    Any provision of this Agreement may be amended or waived if, and only
if, such amendment or waiver is in writing and signed, in the case of an amendment, by each Holder and the Company, or in the case of a waiver, by the party against whom the waiver is to be effective.
No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. 

        Section 4.05.    Notices.    All notices, requests and other communications to any party hereunder shall be in

the fullest extent permitted by the rules of the court in which a suit, action or proceeding is commenced, service of process on such party delivered as provided in Section 4.05 shall be deemed
effective service of process on such party.

ARTICLE 2
 REGISTRATION RIGHTS 

        Section 2.01. (a) Within
five Business Days of the date of this Agreement, the Company shall file with the SEC a Shelf Registration Statement, or amend or
supplement its existing Shelf Registration Statement, with respect to the Registrable Securities then outstanding (which Shelf Registration Statement may also contemplate sales of shares of
Class A Common Stock held by other shareholders). Not less than one Business Day prior to filing such Shelf Registration Statement or such amendment or supplement, the Company shall furnish to
such Holder copies of such Shelf Registration Statement or amendment or supplement to be filed. The prospectus contained in such Shelf Registration Statement shall contain a Plan of Distribution
section in substantially the form attached hereto as Exhibit A. After the Shelf Registration Statement has become effective, for as long as the Company is eligible to use such Shelf
Registration Statement, any Holder may sell shares of Class A Common Stock ("Shares") pursuant to such Shelf Registration Statement, provided
that such sales must be made prior to the 

2

 

second
anniversary of the date hereof and aggregate sales of Registrable Securities under this Agreement shall not exceed 1,500,000 Shares. 

        (b)   All
Holders may sell an aggregate of 125,000 Registrable Securities in each calendar quarter by providing the Company with one full Business Day's prior notice of such
Holder's intention to sell Registrable Securities, subject to the next sentence. The Company will use reasonable endeavors to respond to any such notice as promptly as practical. If the Company
advises such Holder that it does not intend to exercise its rights under Sections 2.01(d) or (e) or if the Company does not respond to such Holder within such one Business Day period,
such Holder may, subject to Section 2.03(e), proceed to sell Registrable Securities during the next thirty Business Days. Any Holder making a sale of Registrable Securities pursuant to this
Section 2.01(b) will promptly notify the Company in writing of the number of Shares sold. 

        (c)   If
in any calendar quarter any sale by a Holder would result in the aggregate amount of all sales of Registrable Securities made by all Holders in such calendar quarter
exceeding 125,000 Registrable Securities, then any future sales of Registrable Securities by any Holder in such calendar quarter shall be in an amount of not less than 50,000 Registrable Securities
and shall be subject to the following conditions. Any Holder wishing to sell Shares pursuant to this Section 2.01(c) shall give the Company two Business Days' written notice of the proposed
sale (the date on which such notice is given, the "Offer Date"), specifying the number of shares to be sold and offering to sell such Registrable
Securities to the Company at a percentage (the "Applicable Percentage") of the Company's current stock price, such Applicable Percentage to be chosen by
such Holder (for example, 99% of the Company's closing stock price on the New York Stock Exchange). The Company (or any assignee of the Company) shall have the option to notify the Holder in writing
within two Business Days of receipt of such written notice from the Holder that it elects to purchase such Registrable Securities (regardless of whether a Blackout Period (as defined below) could then
be imposed by the Company). If the Company (or any assignee of the Company) notifies the Holder that it elects to purchase such Registrable Securities, then the purchase price for such Registrable
Securities shall be the Applicable Percentage of the closing price per Share on the New York Stock Exchange on the trading day immediately preceding the Offer Date. The closing of the purchase of such
Registrable Securities shall take place within five Business Days of such notice from the Company (or any assignee of the Company); provided that if the
Company notifies the Holder that a Blackout Period is in effect at the time of the Offer Date, such closing shall take place within five Business Days of the termination of such Blackout Period. 

        If
the Company advises such Holder that the Company does not intend to purchase such Registrable Securities, or if the Company does not respond to such Holder within such two Business
Day period, such Holder may, subject to Sections 2.01(d) and 2.01(e) and Section 2.03(e), proceed to sell such Registrable Securities during the next thirty Business Days at a price no
less than the Applicable Percentage of the price of the Company's Shares on the New York Stock Exchange at or about the time of sale; provided that if
the Company notifies the Holder that a Blackout Period is in effect at any time from the Offer Date to the end of such thirty Business Day period, such Blackout Period shall be excluded in calculating
such thirty Business Day Period. Any Holder making a sale or sales of Registrable Securities pursuant to this Section 2.01(c) shall promptly notify the Company of the number of Registrable
Securities sold. 

        Sales
of Registrable Securities pursuant to this Section 2.01(c) shall not count against the 125,000 Registrable Securities quarterly limit provided in Section 2.01(b),
regardless of the calendar quarter in which they occur. 

        (d)   Notwithstanding
paragraphs (b) and (c), the Company shall have the right to preempt any sale of Registrable Securities for a period not to exceed 60 days
(in addition to any subsequent holdback period under Section 2.02) with a primary offering by the Company by delivering written notice (within 

3

 

the
one or two Business Day period specified in Section 2.01(b) or (c), as applicable, after the Company has received a notice of proposed sale from a Holder) to the Holder indicating that the
Company has identified a specific business need and use for the proceeds of the sale of such securities and the Company shall use all commercially reasonable efforts to effect a primary registration
within 60 days of such notice. The Company shall not be entitled to exercise this right more than one time in any 12-month period, and during any preemption pursuant to this
Section 2.01(d), the Company will not permit any other stockholder to sell Shares pursuant to the Shelf Registration Statement or any other registration rights agreement with the Company. 

        (e)   Notwithstanding
paragraphs (b) and (c), if the Company shall furnish to the Holder giving notice of a proposed sale of Shares (within the one or two Business Day
period specified in Section 2.01(b) or (c), as applicable), a certificate signed by an officer of the Company stating that the Company is in possession of material, non-public
information (as determined by the Company in consultation with counsel) and it is not in the best interests of the Company to disclose such information in a registration statement at such time, then
the Holder agrees that it will not make any sale of Registrable Securities until the Company advises the Holder that it is permitted to do so (the period of time during which sales of Registrable
Securities may not be made being referred to as a "Blackout Period"); provided, however, that the
Company may not delay sales by Holders pursuant to this Section 2.01(e) for more than 120 days in any 12-month period. The Company will promptly notify the Holders in writing
as soon as sales of Registrable Securities pursuant to the Shelf Registration Statement may resume. Each Holder agrees to treat all communications received from the Company pursuant to this
Section 2.01(e) in the strictest confidence and shall not disseminate such information. The Company agrees to use reasonable best efforts to keep any such Blackout Period to the minimum number
of days possible, consistent with the Company's best interests as determined by the Company in good faith and in consultation with counsel. The Company further agrees that it will not impose any
Blackout Period on a Holder that is not also imposed upon any other Person with securities issued by the Company with registration rights granted by the Company, and that it will not impose a Blackout
Period unless it informs its executive officers and directors of the existence of restrictions on trading in the Company's securities for the duration of such Blackout Period in a manner consistent
with the Company's past practice. 

        Each
Holder agrees that if the date on which such Holder proposes to make a sale of Registrable Securities is at least 45 calendar days, but fewer than 75 calendar days, after the end of
the Company's fiscal year, and the Securities Act requires the Company to include in the Shelf Registration Statement audited financials as of the end of such fiscal year, the Holder will delay any
sale of Registrable Securities for such period as is reasonably necessary to permit the Company to include therein its required audited financial statements for such fiscal year. The Company agrees to
use reasonable best efforts to minimize the length of any delay. 

        (f)    Each
Holder selling Shares agrees to pay all Holder Registration Expenses in connection with such sales, and the Company agrees to pay all Company Registration Expenses
in connection with such sales. 

        (g)   The
Company hereby warrants and represents that as of the date hereof it is eligible to file automatic shelf registration statements pursuant to
Form S-3 and the rules promulgated under the Securities Act. 

        Section 2.02.    Holdback Agreements.    Each Holder agrees not to offer, sell, contract to sell, pledge, grant
any option to purchase, make any short sale or otherwise dispose of any Registrable Securities (other than as part of a registration effected under this Agreement) beginning on the date of any
preliminary prospectus used in connection with any offering conducted as part of a registration effected by the Company, through the period after the pricing date of such offering equal to the lesser
of (i) such period of time as agreed between the managing underwriter of such offering and the 

4

 

Company
and (ii) 120 days, provided that the holdback agreement of such Holder is on no more onerous terms than any other agreements
entered into by any other Person. Notwithstanding the foregoing, the holdback agreement provided under this Section 2.02 shall not restrict any Holder from transferring Registrable Securities
to any Person who agrees to be bound by the provisions hereof. 

        Section 2.03.    Registration Procedures.    Whenever a Holder makes a sale of Shares in accordance with the
terms of this Agreement; 

        (a)   The
Company will, if requested by such Holder, as expeditiously as possible prepare and file with the SEC a prospectus supplement for such sale. 

        (b)   The
Company will, if requested by such Holder, prior to filing a prospectus supplement, furnish to the requesting Holder copies of such prospectus supplement as proposed
to be filed and provide the Holder with a meaningful opportunity, if practical under the circumstances, to comment on the same, and thereafter the Company will furnish to the Participating Holders
such number of copies of such prospectus supplement and such other documents as such Participating Holders may reasonably request in order to facilitate the disposition of the Registrable Securities
owned by such Participating Holders. 

        (c)   The
Company will promptly notify each Participating Holder of any stop order relating to the Shelf Registration Statement issued or threatened by the SEC and take all
reasonable actions required to prevent the entry of such stop order or to remove it if entered. 

        (d)   The
Company will use its best efforts to (i) register or qualify the Registrable Securities under such other securities or blue sky laws of such jurisdictions in
the United States as any Participating Holder reasonably (in light of such Holder's intended plan of distribution) requests and (ii) cause such Registrable Securities to be registered with or
approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company and, subject to the other limitations contained herein, do any
and all other acts and things that may be reasonably necessary or advisable to enable the Participating Holders to consummate the disposition of their Registrable Securities;  provided that the Company
will not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this paragraph (d), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction. 

        (e)   The
Company will immediately notify each Participating Holder of the occurrence of (i) any request by the SEC or any state securities or blue sky authority for a
supplement or amendment to the Shelf Registration Statement or any prospectus included therein or (ii) an event requiring the preparation of a supplement or amendment to the Shelf Registration
Statement or any prospectus included therein so that such Shelf Registration Statement or prospectus will not contain an untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading and promptly prepare and make available to each Participating Holder any such supplement or amendment. Each
Participating Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in this paragraph (e), such Participating Holder will forthwith
discontinue disposition of Registrable Securities until such Participating Holder's receipt of the copies of the supplemented or amended Shelf Registration Statement or prospectus contemplated by this
paragraph (e) and, if so directed by the Company, such Participating Holder will deliver to the Company, or destroy, all copies, other than any permanent file copies then in such Participating
Holder's possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. 

        (f)    The
Company will use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its stockholders, as soon as reasonably
practicable, an earnings statement covering a period of 12 months, beginning within three months after the effective date of the 

5

 

Shelf
Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act. 

        (g)   The
Company may require each Participating Holder to furnish in writing to the Company as promptly as practicable such information regarding the distribution of the
Registrable Securities as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration. The Company agrees that with
respect to a Participating Holder, it shall only include in any registration statement or prospectus (or amendment or supplement thereto), such information regarding such Participating Holder as it
has been provided in writing by or on behalf of such Holder specifically for inclusion in any such document and that the Company shall not amend, alter or change any such information without such
Participating Holder's prior written consent. 

        (h)   The
Company will use its reasonable best efforts to cause all such Registrable Securities to be listed on each securities exchange or quoted on each inter-dealer
quotation system on which the Class A Common Stock is then listed or quoted. 

        (i)    Notwithstanding
anything to the contrary in this Agreement, the Company shall not be required to enter into any agreement with any underwriter or broker-dealer in
connection with any sale of Registrable Securities hereunder, to participate (or cause its directors, employees, advisors or accountants to participate) in any marketing or "due diligence" activities
in connection therewith, or to deliver (or cause to be delivered) any certificates, opinions of counsel or comfort letters in connection therewith. 

        (j)    If
requested by any Participating Holder, the Company will promptly incorporate in a prospectus supplement or post-effective amendment such information
concerning such Participating Holder as such Holder reasonably requests to be included therein and as is appropriate in the reasonable judgment of the Company; in addition, the Company will make all
required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters to be incorporated in such prospectus supplement or
post-effective amendment. 

        Section 2.04.    Indemnification by the Company.    The Company agrees in connection with any sale of Shares
made in accordance with the terms of this Agreement, to indemnify and hold harmless each Participating Holder, its officers, directors and agents, and each person, if any, who controls such Holder
within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities caused by any untrue
statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall
have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement
or omission based upon information furnished in writing to the Company by such Holder or on such Holder's behalf expressly for use therein; provided
that with respect to any untrue statement or omission or alleged untrue statement or omission, the indemnity agreement contained in this paragraph shall not apply to the extent
that any such loss, claim, damage, liability or expense results from the fact that a current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any
free-writing prospectus) was not sent or given to the person asserting any such loss, claim, damage, liability or expense at or prior to the time of sale of the Registrable Securities
concerned to such person if it is determined that the Company has provided such current copy of such preliminary prospectus or prospectus (as amended or supplemented, including by any
free-writing prospectus) and it was the responsibility of such Holder to provide such person with such current copy of such preliminary prospectus or prospectus (as amended or
supplemented, including by any free-writing prospectus) and 

6

 

such
current copy would have cured the defect giving rise to such loss, claim, damage, liability or expense. As a condition to including Registrable Securities in any Shelf Takedown, the Company may
require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by underwriters with respect
to similar securities. 

        Section 2.05.    Indemnification by Participating Holders.    Each Participating Holder agrees, severally but
not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each person, if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Holder, but only (i) with respect to information furnished in
writing by such Holder or on such Holder's behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto,
including any free-writing prospectus, or any preliminary prospectus or (ii) to the extent that any loss, claim, damage, liability or expense described in Section 2.04
results from the fact that a current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing prospectus) was not sent or given to the
person asserting any such loss, claim, damage, liability or expense at or prior to the time of sale of the Registrable Securities concerned to such person if it is determined that it was the
responsibility of such Holder to provide such person with such current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing
prospectus) and such current copy of the preliminary prospectus or prospectus (as amended or supplemented, including by any free-writing prospectus) would have cured the defect giving rise
to such loss, claim, damage, liability or expense; provided, however, that the aggregate amount which any such Holder shall be required to pay pursuant to this
Section 2.05 shall in no event be greater than the amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such loss, claim, damage,
liability or expense. Each such Holder also agrees to indemnify and hold harmless the underwriters of the Registrable Securities, their officers and directors and each person who controls such
underwriters on substantially the same basis as that of the indemnification of the Company provided in this Section. As a condition to including Registrable Securities in any Shelf Takedown, each
Participating Holder may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities. 

        Section 2.06.    Conduct of Indemnification Proceedings.    In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Article 2 such person (an "Indemnified
Party") shall as promptly as practicable notify the person against whom such indemnity may be sought (the "Indemnifying Party")
in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees
and expenses; providedthat the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its
obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually
agreed to the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the Indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall
not be 

7

 

liable
for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall
indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding. 

        Section 2.07.    Contribution.    If the indemnification provided for in this Article 2 is unavailable
to the Indemnified Parties in respect of any losses, claims, damages or liabilities referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities, as between the Company on the one hand and each such Holder on the other,
in such proportion as is appropriate to reflect the relative fault of the Company and of each such Holder in connection with such statements or omissions, as well as any other relevant equitable
considerations. The relative fault of the Company on the one hand and of each such Holder on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such
party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

        The
Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably
incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section, no Holder shall be required to contribute any
amount in excess of the amount by which the total price at which the Registrable Securities of such Holder were offered to the public exceeds the amount of any damages which such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Each such Holder's obligation to contribute pursuant to this Section
is several in the proportion that the proceeds of the offering received by such Holder bears to the total proceeds of the offering received by all such Holders and not joint. 

        Section 2.08.    Participation Limitations.    No Person may participate in a Shelf Takedown hereunder unless
such Person completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the provisions of this Agreement in respect of registration rights. 

        Section 2.09.    Other Indemnification.    Indemnification similar to that specified herein (with appropriate
modifications) shall be given by the Company and each Participating Holder with respect to any required registration or other qualification of securities under any federal or state law or regulation
or governmental authority other than the Securities Act. 

        Section 2.10.    Indemnification Payments.    The indemnification and contribution required by
Sections 2.05, 2.06 and 2.07 hereof shall be made by periodic payments of the amount thereof during the course of any investigation or defense, as and when bills are received or any expense,
loss, damage or liability is incurred; provided that if a final nonappealable determination is made that the party 

8

 

receiving
such expense payments was not entitled to such payments pursuant to the provisions of this agreement, then the party receiving such expense payments shall return such expense payments to the
party that made such payments. 

ARTICLE 3
 RULE 144 

        Section 3.01.    Rule 144.    The Company covenants with each Holder until the second anniversary of the
date hereof that it will file any reports required to be filed by it under the Securities Act and the Exchange Act and that it will take such further action as the Holders may reasonably request to
the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by
Rule 144. Upon the request of any Holder, the Company will deliver to such Holder a written statement as to whether it has complied with such reporting requirements. 

        Notwithstanding
anything in this Agreement to the contrary, a Holder may make unlimited sales pursuant Rule 144 subject to the applicable restrictions thereof. 

ARTICLE 4
 MISCELLANEOUS 

        Section 4.01.    Entire Agreement.    This Agreement constitutes the entire agreement among the parties hereto
and supersedes all other prior agreements and understandings, oral and written, among the parties hereto with respect to the subject matter hereof. 

        Section 4.02.    Binding Effect; Benefit.    This Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, successors, assigns and Permitted Transferees. Nothing in this Agreement, expressed or implied, shall confer on any Person other than the parties hereto,
and their respective heirs, successors, assigns and Permitted Transferees, any rights, remedies, obligations or liabilities under or by reason of this Agreement. 

        Section 4.03.    Assignability.    Other than to Permitted Transferees, no party may assign, delegate or
otherwise transfer any of its rights or obligations under this Agreement, directly or indirectly, whether by operation of law or otherwise, without the written consent of the Company, which the
Company may withhold in its sole discretion, and any attempted assignment contrary to the terms hereof shall be null and void. Neither this Agreement nor any provision hereof is intended to confer
upon any Person other than the parties hereto and their Permitted Transferees any rights or remedies hereunder. 

        Prior
to any transfer of rights to a Permitted Transferee, the transferring Holder shall provide the Company with notice of the Permitted Transferee's name and address and the number of
Registrable Securities with respect to which such rights are being transferred. The Permitted Transferee shall assume the obligations of a Holder under this Agreement in a written instrument delivered
to the Company. If, in connection with such transfer, a Holder has transferred all of its Registrable Securities to such Permitted Transferee, then the transferring Holder shall be released from all
liability under this Agreement other than, and solely with regard to, the provisions of Sections 2.01(a), 2.05, 2.07 and 2.09 of this Agreement in connection with any sale of Registrable
Securities in which such Holder was a Participating Holder and any provision hereof obligating such Holder to pay or reimburse the Company for any Registration Expenses incurred prior to such
transfer. 

        Section 4.04.    Amendment; Waiver.    Any provision of this Agreement may be amended or waived if, and only
if, such amendment or waiver is in writing and signed, in the case of an amendment, by each Holder and the Company, or in the case of a waiver, by the party against whom the waiver is to be effective.
No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further 

9

 

exercise
thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

        Section 4.09.    Specific Enforcement.    Each party hereto acknowledges that the remedies at law of the other

equitable remedy which may then be available. 

        Section 4.10.    Consent to Jurisdiction.    Any suit, action or proceeding seeking to enforce any provision

New York or any other New York State court sitting in New York City, and each of the parties hereby consents to the non-exclusive jurisdiction of such courts (and of the appropriate
appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the
venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any
such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that
service of process on such party as provided in Section 4.05 shall be deemed effective service of process on such party. 

        Section 4.11.    Changes of Terms, Etc.    In the event that the Company should at any time during the term of
this Agreement (i) enter into a registration rights agreement with Tak Tent L Limited that provides for different terms from the selling stockholder's perspective or (ii) after entering
into any such registration rights agreement with Tak Tent L Limited, amend, alter or change any provisions of, or waive any restrictions, under that agreement, the Company shall promptly advise the
Holder of the same in writing and offer such different terms to the Holder under this Agreement, which different terms the Holder may accept, but if the Holder chooses to accept such different terms
it must accept them in their entirety (including any terms which are disadvantageous from the Holder's point of view). Any such change would be effective immediately upon the Holder's acceptance of
the same.

EXHIBIT A  

PLAN OF DISTRIBUTION  

        We are registering certain shares of our Class A Common Stock, to permit the resale of such Common Shares by the holders of thereof from time to time after
the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of Common Shares. We will bear all of our fees and expenses incident to our obligation to
register such Common Shares and the selling stockholders will bear all their fees and expenses in connection with the sale of the Common Shares as set forth in the registration rights agreement. 

        The
selling stockholders or their permitted successors may sell all or a portion of the Common Shares beneficially owned by them and offered hereby from time to time directly or through
one or more underwriters, broker-dealers or agents. If the Common Shares are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or
commissions or agent's commissions. The Common Shares may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the
time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, 

	•
	on
any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

	•
	in
the over-the-counter market;

	•
	in
transactions otherwise than on these exchanges or systems or in the over-the-counter market;

	•
	through
the writing of options, whether such options are listed on an options exchange or otherwise;

	•
	ordinary
brokerage transactions and transactions in which the broker-dealer solicits purchasers;

	•
	block
trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the
transaction;

	•
	purchases
by a broker-dealer as principal and resale by the broker-dealer for its account;

	•
	an
exchange distribution in accordance with the rules of the applicable exchange;

	•
	privately
negotiated transactions;

	•
	short
sales;

	•
	sales
pursuant to Rule 144;

	•
	broker-dealers
may agree with the selling securityholders to sell a specified number of such shares at a stipulated price per share;

	•
	a
combination of any such methods of sale; and

	•
	any
other method permitted pursuant to applicable law. 

        If
the selling stockholders effect such transactions by selling Common Shares to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may
receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of Common Shares for whom they may act as agent or to whom they
may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved).
In connection with sales of Common Shares or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in
short sales of Common Shares in the course of hedging in positions they assume and deliver this prospectus in connection with some or all of those sales and use the Common Shares covered by this
prospectus to 

close
out any short position created in connection with those sales. The selling stockholders may also sell Common Shares short and deliver Common Shares covered by this prospectus to close out short
positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge Common Shares to broker-dealers or other financial institutions that in
turn may sell such shares using this prospectus. 

        The
selling stockholders may pledge or grant a security interest in some or all of the Common Shares owned by them, including to support a derivative or hedging position, and, if they
default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Common Shares from time to time pursuant to this prospectus or any amendment to this
prospectus under Rule 424(b) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee
or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate Common Shares in other circumstances in which case the transferees,
donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 

        The
selling stockholders and any broker-dealer participating in the distribution of the Common Shares may be deemed to be "underwriters" within the meaning of the Securities Act, and any
commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. 

        Under
the securities laws of some states, the Common Shares may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states Common Shares
may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. 

        Any
securities covered by this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 or any other available exemption
rather than pursuant to this prospectus. There can be no assurance that any selling stockholder will sell any or all of the Common Shares registered pursuant to the shelf registration statement, of
which this prospectus forms a part. 

        The
selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the
rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the Common Shares by the selling
stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the Common Shares to engage in market-making activities
with respect to the Common Shares. All of the foregoing may affect the marketability of the Common Shares and the ability of any person or entity to engage in market-making activities with respect to
the Common Shares. 

        We
will indemnify the selling stockholders against certain liabilities, including certain liabilities under the Securities Act, in accordance with the registration rights agreement, or
the selling stockholders will be entitled to contribution. 

        We
will pay certain expenses of the registration of the Common Shares pursuant to the registration rights agreement including, without limitation, Securities and Exchange Commission
filing fees and expenses of compliance with state securities or "blue sky" laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions, if any. 

        Once
sold under the shelf registration statement of which this prospectus forms a part, the Common Shares will be freely tradable in the hands of persons other than our affiliates.
