ITEM 6.

CONTRACTS, ARRANGEMENTS UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

1.

Investor Rights Agreement

SIH is a party to an Investor Rights Agreement, as amended, which are filed as Exhibits 1, 2 and 3 hereto. SIH, under this agreement, is entitled to various registration, preemptive and information rights with respect to the Issuer.  The Investor Rights Agreement, as amended, provides SIH with the following registration rights:

(A) SIH may request, at any time after the earlier of (1) March 9, 2015 and (2) the date that is six months after the effective date of the initial public offering by the Issuer (the “IPO”), that the Issuer will register all or part of the securities held by SIH, and

(B) If the Issuer determines to register any of its securities (other than in certain excluded registrations), the Issuer will promptly notify SIH and use its commercially reasonable efforts to include in that registration all or part of the securities held by SIH that SIH requests to be included.

SIH is entitled to five registration requests on the terms described above under the Investor Rights Agreement. In any company registration, the registration rights of SIH will be pari passu with the registration rights of the holders in the May 2013 private offering of the Issuer. Thereafter, SIH will have priority over the investors in the May 2013 private offering with respect to its specified registrations and any registrations that it requests.

The Investor Rights Agreement, as amended, contains customary provisions relating to registration rights, including, without limitation, rights relating to registration procedures, the Issuer’s obligation to pay registration expenses (other than selling expenses), the Issuer’s right to defer certain registrations, the right of SIH to distribute their equity securities by means of an underwriting, cutback rights, holdback rights, indemnification, reporting, cooperation, transfer and assignment, and termination.

The Investor Rights Agreement, as amended, provides that if the Issuer grants any other person registration rights that are more favorable to the holder of those registration rights than the registration rights of SIH, the registration rights of SIH shall be deemed to be amended to incorporate such more favorable provisions.

The Investor Rights Agreement, as amended, also provides that, so long as SIH continues to own at least 10% of the shares of Issuer’s outstanding common stock, SIH has the right of first refusal to purchase its pro rata share of any securities that the Issuer proposes to issue and sell in a private offering or private placement, subject to certain exceptions. In any such offering, SIH is required to pay the same consideration and accept the same material terms as any other prospective purchaser of such securities.

The Investor Rights Agreement, as amended, also provides that SIH has the right to request and receive certain financial information from the Issuer so long as it continues to own at least 10% of the shares of the outstanding Common Stock.

2.

Shareholders Agreement

SIH is a party to a Shareholders Agreement, as amended, with the Issuer and certain other shareholders of the Issuer, which are filed as Exhibits 4, 5 and 6 hereto, pursuant to which SIH has various governance and other rights with respect to the composition of the Issuer’s board of directors and committees thereof.  More specifically these are:

(A)

Until to the earlier of the completion of the IPO or the date upon which SIH beneficially owns less than 30% of the Issuer’s outstanding Common Stock, SIH is permitted to designate three members to the Issuer’s board of directors, which will include seven members, subject to an increase in the board size to ten members in certain circumstances.

Page 10 of 14

(B)

After the completion of the Issuer’s IPO, SIH will be permitted to designate two members to the Issuer’s board of directors so long as it owns at least 15% of the outstanding Common Stock and one member to the board so long as it owns at least 10% and not more than 15% of the outstanding Common Stock.

(C)

Subject to the corporate governance rules of the principal securities exchange on which the Issuer’s Common Stock is admitted for trading, SIH is permitted to designate one member to each committee of the Issuer’s board of directors.

3.

Voting Agreement

Under the Registration Rights Agreement, if (i) the Issuer has not caused a resale shelf registration statement registering the shares of common stock sold in the May 2013 private offering for resale, or a registration statement relating to an initial public offering of its common stock, to be declared effective by the SEC by June 30, 2014, or (ii) the Issuer has completed an initial public offering of Common Stock prior to June 30, 2014, but it has not caused a shelf registration statement for the resale of the shares sold in the May 2013 private offering to be declared effective by the SEC by the 75th day after the closing date of the initial public offering, subject to extension under certain circumstances, the Issuer will be required to call a special meeting of the shareholders (a “Special Election Meeting”) to consider and vote upon proposals to expand the size of the board of directors by three and to elect three new independent directors nominated by the holders of the shares of common stock sold in the private offering to fill those three vacancies, unless the holders of at least 75% of the outstanding shares of Common Stock entitled to vote thereon, excluding shares beneficially owned by the directors and officers of the Issuer and by SIH, consent to a waiver or deferral of the requirement that the Issuer holds the special meeting. Upon the completion of the May 2013 private offering, the Issuer, SIH and FBR Capital Markets & Co. entered into a Voting Agreement, which is filed as Exhibit 7 hereto, pursuant to which (1) SIH will not be entitled to nominate any director nominees at the Special Election Meeting, (2) any shares Common Stock beneficially owned by SIH will be counted as present for quorum purposes at the Special Election Meeting, (3) SIH will be required to vote all its shares FOR the proposal to expand the size of the board of directors by three at the Special Election Meeting, (4) if the Issuer holds a Special Election Meeting because it has not caused a shelf registration statement for the resale of the shares sold in the May 2013 private offering, or a registration statement relating to an initial public offering of Common Stock, to be declared effective by the SEC by June 30, 2014, SIH will have the right either to vote all of its shares FOR the election of the three nominees at the Special Election Meeting or to withhold its vote with respect to the election of the three nominees, if the Issuer holds a Special Election Meeting because it has completed an initial public offering of its common stock prior to June 30, 2014, but it has not caused a shelf registration statement for the resale of the shares sold in the offering to be declared effective by the SEC by the 75th day after the closing date of the IPO, SIH will be required to vote its shares FOR the election of the three nominees at the Special Election Meeting. In no event will SIH have the right to vote its shares against the election of the three nominees. The term of the Voting Agreement will expire on the first to occur of the date that the Issuer’s obligation to call the Special Election Meeting expires or November 30, 2014.

4.

Lock Up Agreements

SIH is subject to a lock up agreement dated as of September 5, 2013, with the underwriters of the Issuer’s IPO that prevents SIH from disposition, selling, or taking certain actions that might be equivalent to the sale of, its shares of Common Stock of the Issuer except in the IPO and under certain other limited circumstances, for a period of 180 days after the IPO without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated.  The securities reported upon herein held by Long Ridge Equity Partners, LLC, Long Ridge Equity Partners I, LP, and Long Ridge Offshore Subsidiary Holdings, LLC are similarly subject to restrictions on disposition, selling and taking certain actions that might be equivalent to the sale of the shares of Common Stock, by reason of a lock up agreement applicable to Mr. Kevin Bhatt and or James Brown, as directors of the Issuer, due to the fact that they have dispositive authority over the shares held by such entities.

Page 11 of 14

5.

Warrant Agreement

The Issuer has entered into warrant agreements between it and SIH and Long Ridge Equity Partners, LLC, which gives the holder thereof the right to subscribe for and purchase Common Stock (the “Warrants”).  The Warrant held by Long Ridge Equity Partners, LLC was the result of a transfer of a portion of the Warrants originally issued to SIH. Under the Warrants, currently, SIH and Long Ridge Equity Partners, LLC are entitled to purchase up to 238,715 and 3,906 shares of Common Stock, respectively, at an exercise price of $18.00 per share, in each case subject to adjustments for recapitalizations and reclassifications of the Issuer. The term of the Warrants commenced on May 15, 2013, and will remain exercisable for five years until May 15, 2018. The purchase price for the Common Stock subject to the Warrants can be paid, at the election of the holder, by (i) cash or check or (ii) on a net issuance basis, by surrender of all or a portion of the Warrants for Common Stock to be exercised. To the extent the Warrants are not previously exercised as to all shares subject to them, and if the fair market value of one share of Common Stock is greater than the exercise price of $18.00, the Warrants will be deemed automatically exercised on a net issuance basis as of immediately before their expiration. The Warrants are transferrable, in whole or in part, without charge to the holder (except for transfer taxes).
