The Company, IXC Long Distance, Inc., a Delaware corporation ("IXC-LD"), the Shareholders, Telecom One, Inc., a Delaware corporation ("Telecom One"), and IXC-Telecom One Acquisition Corp., a Delaware corporation, have entered into a Stock Acquisition Agreement and Plan of Merger dated January 10, 1997 (the "Acquisition Agreement") pursuant to which IXC-LD, a wholly owned subsidiary of IXC, is acquiring from the Shareholders all of the issued and outstanding shares of capital stock of Telecom One (the "Telecom One Stock"). B. Pursuant to the terms of the Acquisition Agreement, the Company is obligated to issue to the Shareholders a number of shares of common stock, $.01 par value, of the Company (the "IXC Shares") as part of the consideration for the Telecom One Stock purchased by the Company, and the terms of the Acquisition Agreement require the Company to provide the Shareholders certain registration rights with respect to the IXC Shares.

The Company also shall indemnify any underwriter of the Registrable Securities, their officers, directors, partners, members and agents and each person who controls such underwriters on substantially the same basis as that of the indemnification of the Holders provided in this Section 4.1. The indemnity agreement contained in this Section 4.1 shall not apply to amounts paid in settlement of any such loss, claim, damage or liability or any action in respect thereof if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable to any Holder or its officers, directors, partners, members or agents in any such case for any loss, claim, damage, liability or any action in respect thereof to the extent that it arises solely from or is based solely upon and is in conformity with written information relating to such Holder furnished expressly for use in connection with such registration by such Holder or its agents, nor shall the Company be liable to any Holder for any such loss, claim, damage or liability or any action in respect thereof to the extent it arises solely from or is based solely upon (a) any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities delivered by such Holder after the Company had provided written notice to such Holder that such registration statement or prospectus contained such untrue statement or alleged untrue statement of a material fact, (b) 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 after the Company had provided written notice to such Holder that such registration statement or prospectus contained such omission or alleged omission, or (c) the failure of such Holder to deliver any preliminary or final prospectus, or any amendments or supplements thereto, required under applicable securities laws, including the Act, to be so delivered, provided that a sufficient number of copies thereof had been timely provided by the Company to such Holder. 4.2 Indemnification by the Holders. Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, and each of its 6 7 officers, directors, legal counsel and accountants, and each person who controls the Company within the meaning of Section 15 of the Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or 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, or any violation by the Holder of any rule or regulation promulgated under the Act or any state securities laws applicable to the Holder and relating to action or inaction required by the Holder in connection with any such registration, qualification or compliance, and will reimburse each such indemnified person for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by or on behalf of such Holder and stated to be specifically for use therein. Each Holder shall also indemnify and hold harmless any underwriter of the Registrable Securities, their officers, directors, partners, members and agents and each person who controls such underwriters on substantially the same basis as that of the indemnification of the Company provided in this Section 4.2; provided, however, that in no event shall any indemnity obligation under this Section 4.2 exceed the dollar amount of the net proceeds actually received by such Holder from the sale of Registrable Securities which gave rise to such indemnification obligations under such registration statement or prospectus. 4.3 Indemnification Procedures. Each person to be indemnified pursuant to this Article 4 (the "Indemnified Party") will, promptly after its receipt of written notice of the commencement of any action against such Indemnified Party in respect of which indemnity may be sought from an indemnifying person under this Article 4 (the "Indemnifying Party") notify the Indemnifying Party in writing of the commencement thereof, provided, however, that the failure of any person to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent that such Indemnifying Party is actually materially and adversely prejudiced by such failure to give notice. If any such action shall be brought against any Indemnified Party and it shall notify an Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein and, to the extent it may desire, jointly with any other Indemnifying Party similarly notified, to assume the defense thereof with counsel satisfactory to such Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnified Party under this Article 4 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation unless (a) the Indemnified Party shall have employed counsel in an action in which the Indemnified Party and Indemnifying Party are both defendants and there is a conflict of interest between such parties that would prevent counsel from adequately representing both parties, (b) the Indemnifying Party shall not have 7 8 employed counsel satisfactory within the exercise of reasonable judgment of the Indemnified Party to represent the Indemnified Party within a reasonable time after the notice of the commencement of the action, or (c) the Indemnifying Party has authorized the employment of counsel for the Indemnified Party at the expense of the Indemnifying Party. The undertaking contained in this Section 4.3 shall be in addition to any liabilities which the Indemnifying Party may have pursuant to law. 4.4 Contribution Obligations. If the indemnification provided for in this Article 4 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements, actions or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. ARTICLE 5 TRANSFER OF REGISTRATION RIGHTS The rights to cause the Company to register securities granted to a Holder under Articles 2, above, may be transferred or assigned by such Holder to a transferee or assignee in connection with any transfer or assignment of Registerable Securities, provided that: (a) such transfer or assignment may otherwise be effected in accordance with applicable securities laws, (b) prompt written notice of such transfer or assignment is given to the Company, and (c) such transferee or assignee expressly agrees in a writing delivered to the Company to be bound by the provisions of this Agreement. 8 9 ARTICLE 6 DISCONTINUANCE OF DISPOSITION OF REGISTERABLE SECURITIES 6.1 Certain Discontinuances. Each Holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(c)(iii), 3(c)(iv), 3(c)(v), 3(c)(vi) or 3(c)(vii), above, or a Permitted Interruption and/or Necessary Interruption, such Holder will forthwith discontinue disposition of any Registrable Securities covered by a registration statement or prospectus until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(k), above, or until it is advised in writing (the "Advice") by the Company that the use of the applicable prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated or deemed to be incorporated by reference in such prospectus. 6.2 Permitted Interruptions and Necessary Interruptions. Anything in this Agreement to the contrary notwithstanding, it is understood and agreed that the Company shall not be required to prepare or file a registration statement, amendment or post-effective amendment thereto or prospectus supplement or to supplement or amend any registration statement or otherwise facilitate the resale of Registrable Securities, and it shall be free voluntarily to take or omit to take any other action that would result in the impracticality of any such filing, supplement or amendment if such action is taken or omitted to be taken by the Company in good faith and for valid business reasons, including, without limitation, matters relating to acquisitions or divestitures, so long as the Company shall, as promptly as practicable thereafter, make such filing, supplement or amendment and, so long as the Company shall as promptly as is practicable thereafter, comply with the requirements of Section 3(k), above, if applicable (any period described in this Section 6.2 (other than a Necessary Interruption (defined below)) during which Holders of Registrable Securities are not able to sell such Registrable Securities under a registration statement is herein called a "Permitted Interruption"). The period between Permitted Interruptions shall not be less than 30 days; provided, however, that if any event occurs which would make the Registration Statement then in effect materially incorrect or misleading, the Company shall not be required to keep the Registration Statement effective as of such date and continuing for five business days thereafter and the Holders of Registrable Securities shall not sell such securities during such period (each such period is referred to as a "Necessary Interruption"). The Company hereby agrees to notify each of the Holders of Registrable Securities of the occurrence of, and the termination of, each Permitted Interruption and/or Necessary Interruption (the nature and pendency of which need not be disclosed during such Permitted Interruption and/or Necessary Interruption). Permitted Interruptions shall not extend beyond 45 days during the first year of the Two Year Period and 60 days during the second year of the Two Year Period. Notwithstanding the foregoing, there shall be no Permitted Interruptions during the 30-day period immediately following the date the Shelf Registration initially becomes effective. 9 10 6.3 Standoff or Lock-Up Agreement. Each Holder of Registerable Securities agrees in connection with any firmly underwritten public offering of the Company's common stock that, upon request of the Company or the underwriters managing any underwritten offering of the Company's securities, such Holder shall not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registerable Securities (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, during the 14 days prior to, and during the 90-day period (the "Lock-up Period") beginning on, the effective date of the registration statement relating to such offering (except as part of such registration statement). In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registerable Securities until the end of such period. In the event any of Ralph J. Swett, John J. Willingham, Kenneth F. Hinther or John R. Fleming have entered into a lock-up agreement with such underwriters relating to such offering with a lock-up period longer than one day and shorter than 90 days, then such shorter period shall be the Lock-up Period. The Company shall not be required to keep any registration statement effective during any Lock-up Period. ARTICLE 7 TERMINATION OF REGISTRATION RIGHTS Notwithstanding any provision in this Agreement to the contrary, in no event shall any Holder be entitled to request registration or inclusion in any registration pursuant to Article 2, above, after the date on which all Registrable Securities held by such Holder may be sold under Commission Rule 144 during any 90-day period. ARTICLE 8 MISCELLANEOUS 8.1 Amendment. Any modification, amendment or waiver of this Agreement or any provision hereof shall be effective only if in writing and executed by the Holders of at least a majority of the Registrable Securities and the Company. 8.2 Governing Law. This Agreement shall be governed in all respects by the laws of the State of California without regard to its conflicts of laws principles. 8.3 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, permitted assigns, heirs, executors and administrators of the parties hereto. 8.4 Notices. All notices and other communications required or permitted hereunder shall be made in accordance with the Acquisition Agreement. 10 11 8.5 Severability. If any provision of this Agreement shall be judicially determined to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby. 8.6 Entire Agreement. This Agreement, the Registration Rights Agreement with respect to the Final Share Amount and the Acquisition Agreement constitute the full and entire understanding and agreement between the parties with regard to the subject matter hereof. 8.7 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument.
