Cipher satisfies the registrant requirements for the use of a registration statement on Form S-3 to register the Acquired Shares for resale by SoftBank under the Securities Act. Except as disclosed in such Cipher SEC Documents, as of their respective filing dates (or, if amended, as of the date of such amendment), the Cipher SEC Documents did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading. There are no material outstanding or unresolved comments in comment letters from the Commission staff with respect to any of the Cipher SEC Documents.

(p) Except as disclosed in the Cipher SEC Documents, Cipher and its subsidiaries are in material compliance with the applicable requirements of Sarbanes-Oxley Act that are effective as of the date hereof, and any and all applicable rules and regulations promulgated by the Commission thereunder that are effective as of the date hereof.

(r) Cipher is not a U.S. real property holding corporation within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended (the “Code”).

11

one time with respect to such Subscriber Party together with its Permitted Transferees, in the aggregate, that number of shares equal to the lesser of (A) the average daily trading volume of Cipher Common Stock for the four-week period immediately preceding the week during which such sale occurs, as reported on Bloomberg Financial L.P.

(4) any other method of sale mutually agreed by Cipher and the Subscriber Party, acting reasonably and in good faith.

(c) No Transfer to Competitors; Block Transfers. Each Subscriber Party shall not, with respect to the Acquired Shares referred to in Section 5(b), directly or indirectly:

The restrictions in this Section 5(d) (i) shall not apply to any pledge of Acquired Shares as collateral for any financing facility of a Subscriber Party or its Affiliates, provided, that such financing facility is secured by a portfolio of assets or equity interests issued by multiple issuers and (ii) shall terminate with respect to a Subscriber Party when such Subscriber Party no longer owns any Acquired Shares referred to in Section 5(b).

13

(ii) Following the Lock-Up Period and upon request of a Subscriber Party, following receipt by Cipher of an opinion of counsel reasonably satisfactory to Cipher to the effect that such legend is no longer required under the Securities Act and applicable state laws, Cipher shall cause the legend to be removed from any certificate (if applicable) or book entry to be transferred in accordance with the terms hereof.

SoftBank shall be responsible for, and shall indemnify, severally and not jointly, and hold Cipher and its Affiliates harmless from, any withholding or other taxes (including any interest, penalties or additions to tax relating thereto) imposed on or with respect to SoftBank or any of its Affiliates to the extent such taxes are not deducted and withheld from payments made by Cipher to SoftBank in respect of the Acquired Shares.

8. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement; provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach.

9. SoftBank’s Covenants.

(a) Each Subscriber Party and each of its controlled Affiliates, with respect to all of the Cipher Common Stock beneficially owned by each such Person, hereby agrees: at each annual and special meeting of Cipher’s stockholders (“Cipher Stockholders”) held prior to the expiration of the Voting Period (as defined below) (each such meeting, a “Cipher Stockholder Meeting”), and in each written consent or resolutions of any of the Cipher Stockholders in which any such Person is entitled to vote or consent, such Person will (A) appear at such Cipher Stockholder Meeting or otherwise cause all Cipher Common Stock beneficially owned by such Person and its controlled Affiliates to be counted as present for purposes of establishing a quorum, (B) vote, or cause to be voted, all Cipher Common Stock beneficially owned by such Person and its controlled Affiliates on Cipher’s proxy card or voting instruction form (i) in favor of each of the directors nominated by the Board of Directors of Cipher (the “Cipher Board”) and

(b) From the date of this Subscription Agreement until the expiration of the Voting Period, each Subscriber Party and its controlled Affiliates, shall not, and shall cause its controlled Affiliates, principals, directors, general partners, officers, employees and, to the extent acting on its behalf or at its direction, agents and other representatives not to, directly or indirectly:

15

(c) Notwithstanding the foregoing, nothing in Section 9(b) or elsewhere in this Subscription Agreement shall prohibit or restrict any Subscriber Party or its controlled Affiliates, from communicating privately with the Cipher Board or any executive officer or director of Cipher, regarding any matter, so long as such communications are not intended to, and would not reasonably be expected to, require any public disclosure of such communications and subject to the confidentiality obligations to Cipher of any such director or officer.
