		restrictions applicable to the given securities of the Company
		Shareholders’ or the Founders, as the case may be, the
		Company Shareholders (as a group as determined by a
		majority-in-interest) and the Founders (as a group as
		determined by a majority-in-interest) may issue to Parent a
		written request (a “Demand Notice”) that Parent effect the
		registration of all or any portion of their Registrable Securities
		(a “Demand Registration”). Parent shall not be required to (i)
		effect more than two (2) Demand Registrations initiated by
		the Founders or more than four (4) Demand Registrations
		initiated by the Company Shareholders or (ii) effect a Demand
		Registration (x) requested by the Founders if such Founders
		request a registration of shares with a value of less than
		$2,000,000 or (y) requested by the Company Shareholders if
		such Company Shareholders request a registration of shares
		with a value of less than $20,000,000.
	●	Cutbacks: See “Cutbacks” under “Piggyback Rights.”
	●	Withdrawal: The demanding party (based on the majority-in-
		interest) may withdraw the Demand Notice at any time prior
		to the effective date of the registration statement filed in
		response to such Demand Notice if (a) it disapproves of the
		terms of any underwriting or (b) it is not entitled to include all
		of its requested Registrable Securities in the offering. Parent
		shall be responsible for all expenses relating to withdrawn
		registrations.
	●	Underwriter: Following the date that is 24 months after the
		Closing Date, the holders of (A) a majority of Registrable
		Securities or (B) the Founders as a group, provided that their
		demand relates to Registrable Securities with a value of
		$20,000,000 or more, may elect to have an underwritten
		offering, and may select an underwriter mutually agreed upon
		with Parent (subject to both parties acting reasonably).
Piggyback Rights	●	Availability: Company Shareholders and the Founders shall
		have unlimited piggyback rights (including with respect to
		Demand Registrations initiated hereunder) (beginning after
		the expiry of the transfer restrictions applicable to the given

5

 

	securities of the Company Shareholders' or the Founders, as
	the case may be), provided that they shall have no piggyback
	rights for registration statements (i) filed on Form S-8 or
	otherwise in connection with any employee stock option or
	other benefit plan, (ii) filed on Form S-4 or otherwise for an
	exchange offer or offering of securities solely to the
	Company’s existing stockholders, (iii) for an offering of debt
	that is convertible into equity securities of the Company or
	(iv) for a dividend reinvestment plan.
●	Notice: Parent shall give notice of an intended registered
	offering to the Company Shareholders and Founders as soon
	as practicable, but no less than 10 days prior to anticipated
	filing date (after which such holders shall have 5 days to
	respond).
●	Cutbacks: Cutbacks will be permitted in an underwritten
	offering if the underwriter determines in good faith that
	selling the number of shares requested to be included in the
	offering would materially and adversely affect the initial
	requesting party’s ability to sell the shares at the desired
	offering price. If the offering is for Parent’s account, then
	priority will be given to the shares being sold by Parent, then
	to the Company Shareholders and the Founders (pro rata
	based on the number of shares that each elects to include in
	the registration), then to other holders of Parent shares. If the
	offering is initiated by Parent shareholders other than the
	Company Shareholders or the Founders, priority shall be to
	those other shareholders, then to the Company Shareholders
	and the Founders (pro rata based on the number of shares that
	each elects to include in the registration), then to the shares
	being sold by Parent. If the offering is initiated by the
	Company Shareholders or the Founders pursuant to a Demand
	Notice, then priority shall be to the demanding party, then to
	the non-demanding party (i.e. the Company Shareholders or
	the Founders), then to shares being sold by Parent, and then to
	other shareholders; provided that in the case of a demand by
	either party with respect to which the other party has
	exercised piggyback rights, if the underwriter has determined
	there should be a cutback, the party exercising piggyback
	rights may convert its piggyback election to a demand, such
	that the converting party and the demanding party will be
	treated pro rata in such cutback (based on the number of
	shares that each elects to include in the registration); provided
	further that in the event a party converts a piggyback election
	to demand election, such conversion shall be counted as a

6

		demand.
	●	Withdrawal: Any Company Shareholder or Founder may
		withdraw from a piggyback registration at any time. Parent
		shall be responsible for all expenses relating to withdrawn
		registrations.
Shelf Rights	●	Availability: Shelf registration rights shall be available to the
		Company Shareholders (as a group as determined by a
		majority-in-interest) and the Founders (as a group as
		determined by a majority-in-interest) after such time as Parent
		becomes S-3 eligible (and beginning after the expiry of the
		transfer restrictions applicable to the given securities of the
		Company Shareholders’ or the Founders, as the case may be).
		The number and frequency of takedown demands (a “Shelf
		Notice”) to which the Company Shareholders (as a group as
		determined by a majority-in-interest) and the Founders (as a
		group as determined by a majority-in-interest) are entitled
		shall be the same as the entitlement for demand registrations.
		Parent shall not be required to effect a shelf registration
		through an underwritten offering. Parent shall not be required
		to give effect to a Shelf Notice if (a) Form S-3 is not available
		for such an offering or (b) the holders requesting participation
		in the offering propose to sell securities valued at less than
		$2,000,000 (with respect to the Founders) or $20,000,000
		(with respect to the Company Shareholders).
Registration Procedures;	●	The registration procedures and indemnification applicable to
Indemnification and		registrations hereunder shall be substantially similar to the
Contribution		provisions in Sections 3 and 4 of the Founders Registration
		Rights Agreement.
Other
Charter and Bylaws	●	The parties shall take or cause to be taken all lawful action
		necessary to ensure at all times as of and following the
		Closing Date that the certificate of incorporation and by-laws
		of Parent are not inconsistent with the provisions of this
		agreement or the transactions contemplated hereby.
Termination	●	This agreement shall terminate (a) with respect to the
		Company Shareholders, on the date when the Company
		Shareholders hold less than 10% of the outstanding Parent
		common stock, and (b) with respect to all parties, on the date
		of a change of control of Parent, provided that, in either case,
		the registration rights of the Company Shareholders shall
		survive until the Company Shareholders no longer own any

7

Parent common stock, and the registration rights of the 

Founders shall survive until the Founders no longer own any 

Parent common stock or Parent warrants, and the 

indemnification provisions shall survive any termination.
