Indemnification and Contribution. (a) The Company and Primus Telecommunications, Inc., a Delaware corporation, Primus Telecommunications (Australia) Pty. Ltd., a company organized under the laws of Australia, and Primus Telecommunications Pty. Ltd., a company organized under the laws of Australia (collectively, the "Principal Subsidiaries"), jointly and severally, shall indemnify and hold harmless each Underwriter, its officers, employees and directors and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which such Underwriter, officer, employee, director or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto or (B) any blue sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company) specifically for the purpose of qualifying any or all of the Stock under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a "Blue Sky Application") or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, or in any Blue Sky Application any material fact required to be stated therein or necessary, in the case of the Registration Statement or any Blue Sky Application, to make the statements therein not misleading or, in the case of the Preliminary Prospectus or the Prospectus, to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse each Underwriter and each such officer, 17 employee, director or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, officer, employee, director or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred upon written submission to the Company of documentation evidencing such incurrence; provided, however, that the Company and the Principal Subsidiaries shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus or in any such amendment or supplement, or in any Blue Sky Application, in reliance upon and in conformity with the written information concerning such Underwriter furnished to the Company through the Joint Book-Running Managers by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information described in Section 8(e); provided further that as to the Preliminary Prospectus, this indemnity agreement shall not inure to the benefit of any Underwriter or any officer, employee, director or controlling person of that Underwriter on account of any loss, claim, damage, liability or action arising from the sale of Stock to any person by such Underwriter if (i) such Underwriter failed to send or give a copy of the Prospectus, as the same may be amended or supplemented, to that person within the time required by the Securities Act and (ii) the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in the Preliminary Prospectus was corrected in the Prospectus, unless in each case, such failure resulted from noncompliance by the Company with Section 5(c). For purposes of the last proviso to the immediately preceding sentence, the term "Prospectus" shall not be deemed to include the documents incorporated therein by reference, and no Underwriter shall be obligated to send or give any supplement or amendment to any document incorporated by reference in any Preliminary Prospectus or the Prospectus to any person other than a person to whom such Underwriter had delivered such incorporated document or documents in response to a written request therefor. The foregoing indemnity agreement is in addition to any liability which the Company or the Principal Subsidiaries may otherwise have to any Underwriter or to any officer, employee, director or controlling person of that Underwriter. (b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its directors, employees and officers, and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, employee, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto or (B) any Blue Sky Application or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, or in any Blue Sky Application any material fact required to be stated therein or necessary, in the case of the Registration Statement or the Blue Sky Application, to make the statements therein not misleading or, in the case of the Preliminary Prospectus or the Prospectus, to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in the case of clauses (i) and (ii) only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with the written information concerning such Underwriter furnished to the Company through the Joint Book-Running Managers by or on behalf of that Underwriter specifically for inclusion therein as described in Section 8(e), and shall reimburse the Company and any such director, employee, officer or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, employee, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter 18 may otherwise have to the Company or any such director, officer, employee or controlling person. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent the indemnifying party has been materially prejudiced by such failure and provided further that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ separate counsel to represent jointly the indemnified party and its respective directors, employees, officers and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 8 if such indemnified party shall have been advised in writing that the representation of such indemnified party and those directors, employees, officers, and controlling persons by the same counsel would be inappropriate under applicable standards of professional conduct due to actual or potential differing interests between them, and in that event the fees and expenses of such separate counsel shall be paid by the indemnifying party. It is understood that the indemnifying party shall not be liable for the fees and expenses of more than one separate firm (in addition to local counsel in each jurisdiction) for all indemnified parties in connection with any proceeding or related proceedings. Each indemnified party, as a condition of the indemnity agreements contained in Sections 8(a) and 8(b), shall use its reasonable best efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final 19 judgment in favor of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Principal Subsidiaries, on the one hand, and the Underwriters, on the other hand, from the offering of the Stock or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Principal Subsidiaries, on the one hand, and the Underwriters, on the other hand, with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Principal Subsidiaries, on the one hand, and the Underwriters, on the other hand, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting commissions and discounts received by the Underwriters with respect to the Stock purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Stock under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Principal Subsidiaries, on the one hand, or the Underwriters, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Company shall be deemed to be also for the benefit of the Principal Subsidiaries and information supplied by the Company shall also be deemed to have been supplied by the Principal Subsidiaries. Each of the Company and the Principal Subsidiaries and the Underwriters agrees that it would not be just and equitable if contribution pursuant to this Section 8(d) were to be determined by pro rata allocation (even if either the Underwriters or the Company and the Principal Subsidiaries, as the case may be, were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), 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 8(d), 20 no Underwriter shall be required to indemnify or contribute any amount in excess of the amount by which the proceeds received by the Underwriters from an offering of the Stock exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any 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. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. The Underwriters' obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint. (e) The Underwriters severally confirm and the Company acknowledges that the statements with respect to the public offering of the Stock by the Underwriters set forth in the last sentence of the cover page and in paragraphs [3, 8 (regarding stabilization), 9 and 10] under the caption "Underwriting" in, the Prospectus constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus. 9. Default by Any Underwriter. If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the total number of shares of the Firm Stock set opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock which it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Joint Book-Running Managers who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the foregoing maximums are exceeded and the remaining Underwriters or other underwriters satisfactory to the Joint Book-Running Managers do not elect to purchase the shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Option Stock) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. As used in this Agreement, the term "Underwriter" includes, for all purposes of this Agreement unless the 21 context requires otherwise, any party not listed in Schedule I hereto who, pursuant to this Section 9, purchases Firm Stock which a defaulting Underwriter agreed but failed to purchase. Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Joint Book-Running Managers or the Company may postpone the First Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement. 10. Termination. The obligations of the Underwriters hereunder may be terminated by the Joint Book-Running Managers by notice given to and received by the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Section 7(o) or 7(p) shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement. 11. Reimbursement of Underwriter's Expenses. If the Company shall fail to tender the Stock for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters' obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company shall reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Stock and upon demand the Company shall pay the full amount thereof to the Joint Book-Running Managers. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses. 12 Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and: (a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to: Lehman Brothers Inc.

Incorporated, as the Joint Book-Running Managers. 13. Persons Entitled to Benefit of Agreement.

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Company contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act and (B) the indemnity agreement of the Underwriters contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of directors of the Company, officers of the Company who have signed the Registration Statement and any person controlling the Company within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 14. Survival. The respective indemnities, representations, warranties and agreements of the Company and the Principal Subsidiaries, on the one hand, and the Underwriters, on the other hand, contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Stock and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them. 15. Definition of the Terms "Business Day" and "Subsidiary". As used herein, "business day" means any day on which the New York Stock Exchange, Inc. and the Nasdaq National Market are open for trading.

Incorporated, CIBC World Markets Corp., Legg Mason Wood Walker, Incorporated, Jeffries & Company, Inc., Scott & Stringfellow, Inc., and Kaufman Bros., L.P., As Representatives of the several Underwriters named in Schedule I thereto, c/o Lehman Brothers Inc. Three World Financial Center New York, New York 10285 Dear Sirs: PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED ("the Company") 1. We are giving this opinion to you at the request of our client, the Company, in connection with the underwriting agreement, dated October [__], 1999 (the "Underwriting Agreement"), between the Company and you, as Representatives of the several Underwriters listed on Schedule 1 to the Underwriting Agreement, relating to the underwriting of the issue of an aggregate shares of the Company's common stock, par value $.01 per share (the "Common Stock"). 2. For the purpose of this opinion we have examined the following: (a) a copy of the Prospectus, dated October [__], 1999 of the Company (the "Final Prospectus"); (b) a copy of the memorandum and articles of association of Primus Telecommunications Limited (registered in England and Wales under number 2937312) whose registered office is at 4 Victoria Street, London, SW1H 0GT ("PTL"); (c) a microfilmed copy of the file records in respect of PTL maintained at the Company's Registration Office in England and Wales and available for public inspection obtained on October [__], 1999; C-2 (d) the ISVR Licence (as defined below); (e) the IFL License (as defined below); and (f) certificates from Neil L. Hazard and Ali Yazdanpanah in the forms annexed to this letter. 3. On October [ ] 1999, we carried out a company search at the Companies Registration Office, London in respect of PTL. We have not conducted any further such searches since such date. On October [ ] 1999, we carried out a search of the petitions pending at the Central Registry of Winding-Up Petitions in London in respect of PTL. Our search on such date did not reveal the filing of any winding-up order or resolution in respect of PTL or the filing of any appointment of an administrator of PTL. 4. Except as stated above, we have not examined any contracts, instruments or other documents entered into by or affecting the Company or any of its subsidiaries or any corporate records of the Company or any of its subsidiaries and we have not made any other enquiries concerning the Company or any of its subsidiaries. 5. We have not made any investigations of the laws of any jurisdiction other than of England and Wales, the regime and procedures of "French Telecoms Law" and the "EC Directives" (as those terms are defined below and are collectively referred to below as "Relevant Laws"). In particular, we have made no investigation of laws of the State of New York and/or the United States of America as a basis for any of the opinions expressed in this letter, and we do not express or imply any opinion on the laws of any jurisdiction other than the Relevant laws. 6. In rendering this opinion, we have assumed (and have taken no steps to verify independently): (a) the genuineness of all signatures and seals and the authenticity and completeness of all documents purporting to be originals; (b) the conformity to originals of all documents supplied to us as certified or photostatic or facsimile transmitted copies and the authenticity and completeness of the originals of such documents; (c) that the information disclosed by our searches mentioned in paragraph 3 above in relation to PTL was then accurate and has not since altered; that such searches did not fail to disclose any information which had been delivered for registration but did not appear on the respective files in London at the time of our searches; that PTL has not passed a voluntary winding-up resolution; that no petition has been presented or order made by a court for the winding-up, dissolution or C-3 administration of PTL; and that no receiver, trustee, administrator or similar officer has been appointed in relation to PTL or any of PTL's assets or revenues; (d) that there have been no amendments to the memorandum and articles of association of PTL referred to in paragraph 2(b) above; (e) that no event has occurred, action been taken or documents filed, which would, when filed with the Registrar of Companies in England and Wales, result in the alteration of the microfilmed copy of the files of records in respect of PTL referred to in paragraph 2(c) above in a manner which would affect this opinion. 7. Based on and subject to the foregoing and subject to the reservations stated in paragraphs 8 and 9 below and to any matters not disclosed to us, we are of the opinion that: (a) PTL has been duly incorporated and is validly existing as a private limited company under the laws of England and Wales and has the corporate power and authority under such laws to own its property; (b) PTL has all necessary approvals, being: (i) a license issued by or on behalf of the Secretary of State for Trade and Industry (the "Secretary of State") dated 31 December 1997 issued under Section 7 of the Telecommunications Act 1984 ("1984 Act") relating to the provision of international simple voice resale services (the "ISVR License"); and (ii) a license issued by or on behalf of the Secretary of State dated 18 December 1996 issued under Section 7 of the 1984 Act relating to the provision of international facilities-based services (the "IFL License"), to conduct its business in the United Kingdom in the manner described in the Final Prospectus and no other licenses, designations, and/or specifications are required from any other governmental entity in the United Kingdom for PTL to conduct its business in the United Kingdom in the manner described in the Final Prospectus; (c) to the best of our knowledge and belief, each of the ISVR License and IFL License are in full force and effect and there is no pending or existing notice of proceedings relating to revocation or modification of either the ISVR License or the IFL License which would have a material adverse effect on PTL; (d) the descriptions in the Final Prospectus of current statutes of the United Kingdom ("UK") relating to telecommunications, and the respective rules and regulations promulgated thereunder (collectively, "UK Communications Law"), including, C-4 without limitation, the 1984 Act and the statements in the Final Prospectus discussing matters related to UK Communications Law under the captions "Risk Factors--We are subject to potential adverse effects of regulation" and "Business--Government Regulation", are accurate in all material respects and fairly summarize all matters described therein insofar as they related to UK Communications Law; (e) to the best of our knowledge and belief, PTL is not in violation of or in default of any provision of the 1984 Act or any regulation or order made under that Act; (f) to the best of our knowledge and belief, PTL has not been issued with any notification by the Commission of the European Communities informing it that it is in breach of any applicable provision of European law as established under the Treaty of Rome as it relates to the provision of telecommunications services; and (g) the descriptions in the Final Prospectus of current law of the European Union relating to telecommunications, in the form of Directives promulgated by the European Commission ("the Commission") and the Council of Ministers of the European Union ("the Council") (collectively, "the EC Directives") and the statements in the Final Prospectus discussing matters related to the EC Directives under the caption "Business--Government Regulation", are accurate in all material respects and fairly summarize all matters described therein insofar as they relate to the EC Directives; and (h) the description in the Final Prospectus relating to the current French licensing regime for the granting of L34.1 and L33.1 licenses and interconnection procedures (collectively, "French Telecoms Law") under the caption "Business--Government Regulation" is accurate in all material respects and fairly summarizes such regime and procedures. 8. This opinion is given solely in respect of the date hereof and on the basis that it is to be governed by and construed in accordance with the laws of England and Wales. 9. This opinion is addressed solely to you for your own us and benefit in connection with the Underwriting Agreement and may not be disclosed to or relied upon by anyone else without our express written consent.
