Stockholders Entitled to Vote. Holders of record of the Company's common stock, par value $.01 per share (the "Common Stock") and Series C Convertible Preferred Stock, par value $.01 per share (the "Preferred Stock"), at the close of business on the Record Date are entitled to receive Notice of the Annual Meeting and vote such shares held by them at the Annual Meeting or at any adjournments or postponements thereof. Each share of Common Stock outstanding on the Record Date entitles its holder to cast one vote on the election of each nominee for director and on any other matter that may properly come before the Annual Meeting. Each holder of Preferred Stock is entitled to cast a number of votes as would pertain to the full number of shares of Common Stock into which shares of Preferred Stock held by such holder would be convertible as of the Record Date.

Quorum. The presence at the meeting, either in person or by proxy, of stockholders entitled to cast a majority of the votes entitled to be cast at the Annual Meeting will constitute a quorum for the transaction of business at the Annual Meeting. Abstentions, votes withheld and broker non-votes (i.e., shares held by a broker or nominee which are represented at the meeting, but with respect to which the broker or nominee is not voting on a particular proposal) will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining if a quorum exists. Abstentions will have the effect of votes against a particular proposal, and broker non-votes will have no effect on the outcome of the vote on a particular proposal. Stockholders are not entitled to cumulative voting in the election of directors. Directors are elected by the affirmative vote of a plurality of the votes of the shares entitled to vote, present in person or represented by proxy, and votes may be cast in favor of or withheld from each director nominee.

Voting. If the accompanying Proxy Card is properly signed, returned to the Company and not revoked, it will be voted as directed by the stockholder. The persons designated as proxy holders on the Proxy Card will, unless otherwise directed, vote the shares represented by such proxy IN FAVOR OF

the election of all nominees for the Board of Directors named in this Proxy Statement, IN FAVOR OF the amendment to the Employee Stock Option Plan and as recommended by the Board of Directors with regard to any other matters, or, if no such recommendation is given, in their own discretion.

Revocation of a Proxy. A stockholder may revoke a previously granted proxy at any time before it is exercised by filing with the Secretary of the Company a written notice of revocation or a duly executed proxy bearing a later date, or by attending the Annual Meeting and voting in person.

You should rely only on the information provided in this Proxy Statement. The Company has authorized no one to provide you with different information. You should not assume that the information in this Proxy Statement is accurate as of any date other than the date of this Proxy Statement or, where information relates to another date set forth in this Proxy Statement, then as of that date.

The Board of Directors has an Audit Committee, a Compensation Committee and a Nominating Committee. The Board of Directors has delegated certain functions to these committees as follows:

Audit Committee. During the year ended December 31, 2002, the Audit Committee held five meetings. The Audit Committee currently consists of Messrs. Puente (Chairman), Karp, Pizzani and Hershberg. The Audit Committee has the authority and responsibility to hire one or more independent public accountants to audit the Company's books, records and financial statements and to review the Company's systems of accounting (including its systems of internal control), to discuss with such independent public accountants the results of such audit and review, to conduct periodic independent reviews of the systems of accounting (including systems of internal control), and to make reports periodically to the Board of Directors with respect to its findings.

All of the members of the Audit Committee are independent of the Company (as defined under current Rule 4200(a)(15) of the National Association of Securities Dealers' ("NASD") listing standards).

Compensation Committee. During the year ended December 31, 2002, the Compensation Committee, which consists of Messrs. Hershberg (Chairman) and Earle, held three meetings and acted by written consent on two occasions. The Compensation Committee is responsible for fixing the compensation of the Chief Executive Officer and the other executive officers, deciding other compensation matters such as those relating to the operation of the Primus Telecommunications Group, Incorporated Stock Option Plan, as amended (the "Employee Option Plan"), and the Director Stock Option Plan of Primus Telecommunications Group, Incorporated, as amended (the "Director Option Plan"), including the award of options under the Employee Option Plan, and approving certain aspects of the Company's management bonus plan.

Nominating Committee. During the year ended December 31, 2002, the Nominating Committee, which consists of Messrs. Kaul (Chairman) and Puente, held one meeting. The Nominating Committee is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company, and making recommendations to the Board regarding affairs relating to directors of the Company (excluding director compensation which is the responsibility of the Outside Director Compensation Committee, which consists of Messrs. Singh and DePodesta).

Compensation of Directors

The Company pays non-employee directors an annual fee of $30,000, reimburses their expenses and pays a $2,500 supplement for each meeting attended in person. In addition, the Company grants each person who becomes a non-employee director on the date of initial election, and upon each date of re-election, options to purchase 45,000 shares of the Common Stock pursuant to the Director Option Plan, which options have an exercise price equal to the fair market value of the Common Stock as of the grant date and vest one-third upon the grant date, and one-third on each of the first and second anniversaries of the grant date.

PROPOSAL 2
APPROVAL OF THE COMPANY'S EMPLOYEE STOCK OPTION PLAN, AS AMENDED

The Company's Employee Stock Option Plan (the "Employee Plan") provides for the grant of stock options at an exercise price of not less than 100% of the Common Stock's fair value at the date of grant. The total number of shares of Common Stock authorized for issuance under the Employee Plan is 9,000,000. The last amendment to the Employee Plan that increased the number of options available for grant was approved in 2001. Under the Employee Plan, awards may be granted to key employees of the Company and its subsidiaries in the form of incentive stock options or nonqualified stock options. The Employee Plan allows the options to vest over a period of up to three years, and no option will be exercisable more than ten years from the date it is granted. The Board of Directors has authorized an increase in the number of shares of Common Stock issuable under the Employee Plan to 13,000,000 and an extension of the expiration date of the Employee Plan from January 2, 2005 to January 2, 2010 (the Employee Plan, as so amended being referred to as the "Amendment"). If all 13,000,000 options were granted and exercisable they would comprise 13% of the Company's Common Stock on a fully-diluted basis.

The Company is amending the Employee Plan in light of the grant of approximately 2.4 million stock options during January and February 2003 (the "2003 Awards"). As a result of the 2003 Awards, approximately 265,000 shares remain authorized for further option awards under the Employee Plan as of March 31, 2003, before giving effect to the Amendment. The 2003 Awards were made to executive management and employees to provide additional incentives and to reward employees for effecting significant improvements in the Company's operating results, capital resources and liquidity. The January 2003 Awards to the Named Executive Officers were granted after assigning a value to the options as a component of the total compensation package. Stock option grants to the Named Executive Officers pursuant to the 2003 Awards are summarized below:

Named Executive Officer	Date of Award	Exercise Price of Option		Number of Shares Subject to Option Award
K. Paul Singh Chairman of the Board of Directors, President and Chief Execuitve Officer	1/10/2003 2/12/2003	$ $	1.90 1.98	250,000 1,100,000
Neil L. Hazard Executive Vice President, Chief Operating Officer and Chief Financial Officer	1/10/2003	$	1.90	100,000
John F. DePodesta Executive Vice President and Director	1/10/2003	$	1.90	100,000
John Melick Senior Vice President and Co-President of Primus Telecommunications, Inc.	1/10/2003	$	1.90	50,000
Jay Rosenblatt Senior Vice President and Co-President of Primus Telecommunications, Inc.	1/10/2003	$	1.90	50,000

Since the Compensation Committee of the Board of Directors makes awards of stock options pursuant to the Employee Plan on a discretionary basis, it is not possible to determine or estimate the amount of any future awards to any of the Named Executive Officers pursuant to the Amendment. No option awards will be made to non-employee directors pursuant to the Amendment.

The Employee Plan has been approved by the stockholders of the Company. The Company seeks stockholder approval of the Amendment. The Board of Directors recommends that stockholders vote IN FAVOR OF the Amendment. Information regarding the Employee Plan and other equity incentive plans of the Company is summarized below.

The following table provides certain information with respect to all of the Company's equity compensation plans in effect as of December 31, 2002.

***		Excludes the additional 4,000,000 options authorization currently proposed for stockholder approval through the Amendment.
****		Represents the number of authorized but unissued shares under the Restricted Plan.

The Company sponsors a Restricted Stock Plan (the "Restricted Plan") to facilitate the grant of restricted stock to selected individuals who contribute to the development and success of the Company and a Director Stock Option Plan (the "Director Plan") for non-employee directors. The total number of shares of Common Stock that may be granted under the Restricted Plan is 750,000. During the years ended December 31, 2001 and 2000, the Company issued 17,643 shares and 3,000 shares, respectively, of restricted stock under the Restricted Plan at fair value to certain eligible agents. These restricted shares vest ratably on the issue date, first anniversary and second anniversary of the issue date based on a continued relationship. The Company did not issue any restricted stock under the Restricted Plan for the year ended December 31, 2002. The Restricted Plan is the only equity compensation plan of the Company that was in effect as of December 31, 2002 and adopted without the approval of the Company's stockholders (750,000 shares authorized, 694,857 remaining available). Under the Director Plan, an option is granted to each qualifying non-employee director on the date of initial election, and upon each date of re-election to purchase 45,000 shares of Common Stock, which vests one-third as of the grant date, and one-third on each of the first and second anniversaries of the grant date. The option price per share is the fair market value of a share of Common Stock on the date the option is granted. No option will be exercisable more than ten years from the date of grant. An aggregate of 600,000 shares of Common Stock was reserved for issuance under the Director Plan. The Director Plan and the Employee Stock Purchase Plan ("ESPP") were approved by the Company's stockholders.

The Company sponsors an ESPP that permits eligible employees of the Company and its subsidiaries to purchase shares of Common Stock from the Company by electing to have the Company deduct a specific dollar amount per month from their compensation. The minimum employee payroll deduction per month is 1% of the employee's compensation and the maximum is 15%. Elections to

participate in the ESPP are made for specified periods referred to as "Option Periods." At the end of each Option Period, the Company applies the amount deducted from each employee's compensation to the purchase of shares of Common Stock to be issued to the employee. The purchase price for such shares is the lower of: (i) 85% of the closing market price on the first trading day of the Option Period or (ii) 85% of the closing market price on the last trading day of the Option Period. No employee may participate in ESPP if: (i) immediately after the Option Period such employee would own more than 5% of the Company's Common Stock, or (ii) immediately after the Option Period such employee would have purchased more than $25,000 of the Company's Common Stock in the current calendar year.

An employee may elect to participate in the ESPP after six months of employment and must so elect prior to the beginning of an Option Period. An employee may also at any time elect to withdraw from the ESPP and have the employee's contribution returned to him or her, or to terminate his or her participation for the remainder of an Option Period. An aggregate of 2,000,000 shares of Common Stock were reserved for issuance under the ESPP. The ESPP was approved by the Company's stockholders.

Employment Agreement

The Company has an employment agreement with Mr. Singh (the "Singh Agreement"). The Singh Agreement initially was a five-year contract, with a term beginning on June 1, 1994 and continuing until May 30, 1999, and now continues from year to year unless terminated. Under the terms of the Singh Agreement, Mr. Singh is required to devote his full-time efforts to the Company as Chairman of the Board, President and Chief Executive Officer. The Company is required to compensate Mr. Singh at an annual rate of at least $250,000 effective January 1, 1997 (which amount is reviewed annually by the Board of Directors and is subject to increase at their discretion). The Company is also obligated to (i) allow Mr. Singh to participate in any bonus or incentive compensation plan approved for senior management of the Company, (ii) provide life insurance in an amount equal to three times Mr. Singh's base salary and disability insurance which provides monthly payments in an amount equal to one-twelfth of his then applicable base salary, (iii) provide medical insurance for him and his family and (iv) pay for Mr. Singh's personal tax and financial planning services.

The Company may terminate the Singh Agreement at any time in the event of his disability or for cause, each as defined in the Singh Agreement. Mr. Singh may resign from the Company at any time without penalty (other than the non-competition obligations discussed below). If the Company terminates the Singh Agreement for disability or cause, the Company will have no further obligations to Mr. Singh. If, however, the Company terminates the Singh Agreement other than for disability or cause, the Company must pay Mr. Singh one-twelfth of his then applicable base salary as severance pay. If Mr. Singh resigns, he may not directly or indirectly compete with the Company's business until six months after his resignation. If the Company terminates Mr. Singh's employment for any reason, Mr. Singh may not directly or indirectly compete with the Company's business until six months after the final payment of any amounts owed to him under the Singh Agreement becomes due.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Compensation Committee consists of Messrs. Hershberg and Earle. Set forth below is the full report of the Compensation Committee regarding the compensation of executive officers on account of fiscal year 2002. Notwithstanding anything to the contrary set forth in any of the Company's filings under the Securities Act of 1933 or the Securities Exchange Act of 1934 that might incorporate SEC filings, in whole or in part, this Compensation Committee Report on Executive Compensation will not be incorporated by reference into any such filings.

General

During 2002, the compensation of the executive officers was administered and determined by the Compensation Committee of the Board of Directors. The Company's executive compensation programs are designed to attract, motivate and retain the executive talent needed to optimize stockholder value in a competitive environment. The programs are intended to support the goal of increasing stockholder value while facilitating the business strategies and long-range plans of the Company.

Compensation Policy and Philosophy

The Company's executive compensation policy (i) is designed to establish an appropriate relationship between executive pay and the Company's annual performance against annual budgets and relative to the performance of the peer group of the industry sector, its long-term growth objectives and its ability to attract and retain qualified executive officers, and (ii) is based on the belief that the interests of the executives should be closely aligned with the Company's stockholders. In support of this philosophy, a meaningful portion of each executive's compensation is placed at-risk and linked to the accomplishment of specific results that are expected to lead to the creation of value for the Company's stockholders from both the short-term and long-term perspectives. The Compensation Committee believes that cash compensation in the form of salary and performance-based incentive bonuses provides Company executives with short-term rewards for success in operations, and that long-term compensation through the award of stock options encourages growth in management stock ownership which are intended to lead to the creation of value for the Company's stockholders and expansion of management's stake in the long-term performance and success of the Company. The Compensation Committee considers all elements of compensation, including the valuation of options, and the compensation policy when determining individual components of pay.

The Compensation Committee believes that leadership and motivation of the Company's employees are critical to achieving the objectives of the Company. The Compensation Committee is responsible for ensuring that its executive officers are compensated in a way that furthers the Company's business strategies and which aligns their interests with those of the stockholders. To support this philosophy, the following principles provide a framework for executive compensation: (i) offer compensation opportunities that attract the best talent to the Company; (ii) motivate individuals to perform at their highest levels; (iii) reward outstanding achievement; (iv) retain those with leadership abilities and skills necessary for building long-term stockholder value; (v) maintain a significant portion of executives' total compensation at-risk, tied to both the annual and long-term financial performance of the Company and the creation of incremental stockholder value; and (vi) encourage executives to manage from the perspective of owners with an equity stake in the Company.

Executive Compensation Components

As discussed below, the Company's executive compensation package is primarily comprised of three components: base salary, annual incentive bonuses and stock options. In making its

determinations, the Compensation Committee considered five external compensation surveys and studies of comparable entities.

Base Salary. Generally, the Compensation Committee approves the base salaries of the executive officers based on (i) salaries paid to executive officers with comparable responsibilities employed by companies with comparable businesses, (ii) performance and accomplishment of the Company in 2002, which is the most important factor, and (iii) individual performance reviews for 2002 for most executive officers. The Compensation Committee reviews executive officer salaries annually and exercises its judgment based on all the factors described above in making its determination, subject to the terms of such officer's employment agreement. No specific formula is applied to determine the weight of each criterion.

Annual Incentive Bonuses. Annual incentive bonuses for the Chief Executive Officer and the other Named Executive Officers were paid based upon the following criteria: (i) the Company's financial performance for the current year, which for 2002 included accelerated earnings before interest, tax, depreciation and amortization expenses ("EBITDA") generated from cost reductions and increased operational efficiency; (ii) cash generation initiatives and raising debt and equity capital; (iii) the furthering of the Company's strategic position in the marketplace; (iv) debt and interest expense reduction through restructuring activities conducted exclusively by senior management without the assistance and related expense of external financial advisors; and (v) individual merit. In addition to regular annual incentive bonuses, the Compensation Committee, in November 2001, authorized a special bonus program to provide incentives for enhancing the Company's cash flow attributable to operations for the period from November 2001 to February 2002. Half of the special bonus that is attributable to the success of each applicable Named Executive Officer for January and February 2002 is reflected in the Summary Compensation Table on page 9. In return for the special bonus, each recipient entered into a retention agreement requiring the officer to remain with the Company through October 1, 2002. The Compensation Committee also authorized a special bonus program for 2002 geared to the achievement of quarterly EBITDA goals. Under the program, if a quarterly EBITDA goal was not met, no bonus would be paid. Given the Company's improved operating performance, the Compensation Committee adjusted the special bonus program for the latter half of 2002 by increasing the previously established EBITDA goals. While the incentive bonuses paid in 2002 are materially larger than prior years, they reflect the accomplishment of significantly improved financial and operating results in the current business environment.

Long-Term Incentive Compensation. Stock options encourage and reward effective management which results in long-term corporate financial success, as measured by stock price appreciation. The Compensation Committee believes that option grants afford a desirable long-term compensation method because they closely ally the interests of management with stockholder value and that grants of stock options are the best way to motivate executive officers to improve long-term stock market performance. The vesting provisions of options granted under the Employee Plan are designed to encourage longevity of employment with the Company and generally extend over a three-year period. The number of options granted during 2002 to each Named Executive Officer was solely the result of an option exchange program. In May 2002, the Company offered employees the opportunity to exchange all outstanding stock options with exercise prices over $2.00 for replacement options to purchase shares of the Company's Common Stock on the date that was six months and one day after the expiration date of the offer. The option exchange program was implemented in order to provide the executive officers and employees with a long-term incentive to increase stockholder value. Most earlier option grants were far above current market price and provided minimal long-term reward for improved stock market performance.

Compensation of Chief Executive Officer

The Compensation Committee believes that K. Paul Singh, the Company's Chief Executive Officer, provides valuable services to the Company and that his compensation should therefore be competitive with that paid to executives at comparable companies. In addition, the Compensation Committee believes that an important portion of his compensation should be based on performance. Mr. Singh's annual salary for 2002 was $415,000. The annual performance bonus paid to Mr. Singh for 2002 was $1,200,000. The factors that the Compensation Committee considered in setting his total compensation for the year 2002 were his individual accomplishments and leadership in driving the overall Company performance in exceeding both the quarterly and annual EBITDA goals and debt reduction targets and in obtaining new financing as well as pay practices of peer companies relating to executives of similar responsibility. Mr. Singh's total cash compensation in 2003 will be $400,000.

Internal Revenue Code Section 162

The Compensation Committee has reviewed the potential consequences for the Company of Section 162(m) of the Internal Revenue Code, which imposes a limit on tax deductions for annual compensation in excess of one million dollars paid to any of the five most highly compensated executive officers, including the Chief Executive Officer. It is the current policy of the Compensation Committee to maximize, to the extent reasonably possible, the Company's ability to obtain a corporate tax deduction for compensation paid to executive officers of the Company to the extent consistent with the best interests of the Company and its stockholders. Due to the Chief Executive Officer's annual incentive bonus being performance-based in calendar year 2002, the limitation under Section 162(m) had no net tax effect on the Company. The limitations of Section 162(m) are not expected to have a material effect on the Company in calendar year 2003.

	Respectfully Submitted,
	The Compensation Committee of the Company's Board of Directors

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee of the Board of Directors consists of Messrs. Hershberg and Earle, who were not at any time officers or employees of the Company. No executive officer of the Company serves as a member of the Board of Directors or compensation committee of another entity which has one or more executive officers that will serve as a member of the Board of Directors or the Company's Compensation Committee.

In June 1999, the Company contracted with a vendor to provide one satellite earth station in Australia and to provide, operate and maintain a satellite link between the Company's router in Los Angeles, California and the earth station, as well as to monitor a satellite earth station in London. David Hershberg, one of the Company's directors, is the Chairman and a stockholder of the vendor providing such services. The Company paid the vendor approximately $100,000 in 2000 and incurred monthly charges of $148,000 (totaling $1.78 million) in 2001 and $150,000 (totaling $0.9 million) in 2002 until the contract was terminated in June 2002. An additional termination fee of $357,500 was paid during the year ended December 31, 2002.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee has reviewed and discussed the audited consolidated financial statements of the Company for fiscal year 2002 with the Company's management, and also has discussed with Deloitte & Touche LLP, the Company's independent auditors, the matters required to be discussed by Statement on Auditing Standards No. 61, "Communication with Audit Committees." The Audit Committee has received both the written disclosures and the letter from Deloitte & Touche LLP required by Independence Standards Board Standard No. 1, and has discussed with Deloitte & Touche LLP the independence of Deloitte & Touche LLP from the Company.

Based on the foregoing, the Audit Committee recommended to the Board of Directors of the Company that the audited consolidated financial statements of the Company for fiscal year 2002 be included in the Company's Annual Report on Form 10-K filed with the SEC on March 31, 2003.

In addition, the Audit Committee has considered whether the provision of services by Deloitte & Touche LLP falling under the headings "Financial Systems Design and Implementation Fees" and "All Other Fees" (see "Other Matters—Relationship with Independent Accountants" on page 24) is compatible with maintaining the independence of Deloitte & Touche LLP from the Company, and has determined that the provision of such services is compatible with maintaining such independence.

Notwithstanding anything to the contrary set forth in any of the Company's filings under the Securities Act of 1933 or the Securities Exchange Act of 1934 that might incorporate SEC filings, in whole or in part, this Report of the Audit Committee will not be incorporated by reference into any such filings.

Interest is compounded quarterly at a rate of 6% per annum and payable upon maturity. In February 2002, the Company entered into a retention agreement with Mr. Rosenblatt which provided that the personal recourse feature of the notes would be removed if Mr. Rosenblatt remained employed with the Company through May 1, 2003. The shares of the Company's Common Stock acquired upon exercise of Mr. Rosenblatt's options will continue to be held by the Company as collateral for the notes, which collateral had a value of $62,651 at March 31, 2003.

OTHER MATTERS

Other Business

The Board of Directors knows of no other matters that will be presented at the Annual Meeting other than as set forth in this Proxy Statement. However, if any other matter properly comes before the meeting, or any adjournment or postponement thereof, it is intended that proxies in the accompanying form will be voted, to the extent permitted by applicable law, in accordance with the judgment and at the discretion of the persons named therein.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's directors, executive officers and persons who own more than ten percent of a registered class of the Company's equity securities (collectively, "Reporting Persons") to file with the Securities and Exchange Commission initial reports of changes in ownership of the Common Stock and other equity securities of the Company. Reporting Persons are additionally required to furnish the Company with copies of all Section 16(a) forms they file. Based solely on a review of Forms 4 and 5 filed by the Reporting Persons for the 2002 reporting season, the Company is aware of no late filings or omissions by the Reporting Persons.

Relationship with Independent Accountants

The Company's consolidated financial statements for the fiscal year ended December 31, 2002 have been audited by Deloitte & Touche LLP. Representatives of Deloitte & Touche LLP are expected to be available at the meeting to respond to appropriate questions and to make a statement if they desire to do so.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g. brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are Company stockholders will be householding our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once

you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your broker or direct your written request to Jordan Darrow, Vice President of Investor Relations, Primus Telecommunications Group, Incorporated, 1700 Old Meadow Road, McLean, Virginia 22102, or contact Jordan Darrow at (212) 703-0116. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker.

Annual Report

A copy of the Company's Annual Report on Form 10-K for the year ended December 31, 2002 filed with the Securities and Exchange Commission accompanies this Proxy Statement.

Stockholder Proposals

In order for any proposal pursuant to Rule 14a-8 of the rules promulgated under the Securities Exchange Act of 1934 to be eligible for inclusion in the Company's proxy materials for the 2004 Annual Meeting of Stockholders, such proposal must, in addition to meeting the stockholder eligibility and other requirements of the Securities and Exchange Commission's rules governing such proposals, be received not later than December 31, 2003 by the Secretary or Assistant Secretary of the Company at the Company's principal executive offices, 1700 Old Meadow Road, McLean, Virginia 22102.

Solicitation of Proxies

The cost of solicitation of proxies by the Board of Directors will be borne by the Company. Proxies may be solicited by mail, personal interview, telephone, facsimile or telegraph and, in addition, directors, officers and regular employees of the Company may solicit proxies by such methods without additional remuneration. Banks, brokerage houses and other institutions, nominees or fiduciaries will be requested to forward the proxy materials to beneficial owners in order to solicit authorizations for the execution of proxies. The Company will, upon request, reimburse such banks, brokerage houses and other institutions, nominees and fiduciaries for their expenses in forwarding such proxy materials to the beneficial owners of the Common Stock.

THE COMPANY WILL PROVIDE TO EACH PERSON SOLICITED, WITHOUT CHARGE EXCEPT FOR EXHIBITS, UPON REQUEST IN WRITING, A COPY OF ITS ANNUAL REPORT ON FORM 10-K, INCLUDING THE FINANCIAL STATEMENTS AND FINANCIAL STATEMENT SCHEDULE, AS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION FOR THE FISCAL YEAR ENDED DECEMBER 31, 2002. REQUESTS SHOULD BE DIRECTED TO INVESTOR RELATIONS, PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED, 1700 OLD MEADOW ROAD, MCLEAN, VIRGINIA 22102.

STOCKHOLDERS ARE URGED TO IMMEDIATELY MARK, DATE, SIGN AND RETURN THE ENCLOSED PROXY IN THE ENVELOPE PROVIDED, TO WHICH NO POSTAGE NEED BE AFFIXED IF MAILED IN THE UNITED STATES. STOCKHOLDERS MAY ALSO VOTE THEIR SHARES USING THE TWELVE (12) DIGIT CONTROL NUMBER FOUND ON THEIR VOTE INSTRUCTION FORM VIA THE INTERNET AT PROXYVOTE.COM OR BY PHONE AT 1-800-454-8683.

The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of cash, check, promissory notes or Shares having a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method of payment permitted under any laws to which the Company is subject which is approved by the Board. In making

its determination as to the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company.

(i): If the consideration for the exercise of an Option is a promissory note, it may, in the discretion of the Board, be either full recourse or nonrecourse and shall bear interest at a per annum rate which is not less than the applicable federal rate determined in accordance with Section 1274(d) of the Code as of the date of exercise. In such an instance, the Company may, in its sole discretion, retain the Shares purchased upon exercise of the Option in escrow as security for payment of the promissory note.
(ii): If the consideration for the exercise of an Option is the surrender of previously acquired and owned Shares, the Optionee will be required to make representations and warranties satisfactory to the Company regarding his title to the Shares used to effect the purchase (the "Payment Shares"), including without limitation, representations and warranties that the Optionee has good and marketable title to such Payment Shares free and clear of any and all liens, encumbrances, charges, equities, claims, security interests, options or restrictions, and has full power to deliver such Payment Shares without obtaining the consent or approval of any person or governmental authority other than those which have already given consent or approval in a manner satisfactory to the Company. The value of the Payment Shares shall be the Fair Market Value of such Payment Shares on the date of exercise as determined by the Board in its sole discretion, exercised in good faith. If such Payment Shares were acquired upon previous exercise of incentive stock options granted within two years prior to the exercise of the Option or acquired by the Optionee within one year prior to the exercise of the Option, such Optionee shall be required, as a condition to using the Payment Shares in payment of the exercise price of the Option, to acknowledge the tax consequences of doing so, in that such previously exercised incentive stock options may have, by such action, lost their status as incentive stock options, and the Optionee may have to recognize ordinary income for tax purposes as a result.
(iii): To the extent permitted under the Section 16b-3 of the Exchange Act, and in the sole discretion of the Committee, the Company may cooperate in a "cashless exercise" of an Option. The cashless exercise shall be effected by the Participant delivering to a securities broker, who is a registered securities broker acceptable to the Company and who agrees to effect such cashless exercise, instructions to sell a sufficient number of Shares to cover the costs and expenses associated therewith.

(d) Form of Option. The Option Agreement will state whether the Option granted is an incentive stock option or a non-qualified stock option, and will constitute a binding determination as to the form of Option granted.

(e) Exercise of Options. Any Option granted hereunder shall be exercisable at such times and under such conditions as shall be set forth in the Option Agreement (as may be determined by the Board and as shall be permissible under the terms of the Plan), which may include performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan.

An Option may be exercised in accordance with the provisions of this Plan as to all or any portion of the Shares then exercisable under an Option from time to time during the term of the Option. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company at its principal executive office in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company, accompanied by any agreements required by the terms of the Plan and/or Option Agreement, including an executed Stock Purchase Agreement. Full payment may consist of such consideration and method of payment allowable under Section 6 of the

Plan. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Option is exercised, except as provided in Section 8 of the Plan.

As soon as practicable after any proper exercise of an Option in accordance with the provisions of the Plan, the Company shall, without transfer or issue tax to the Optionee, deliver to the Optionee at the principal executive office of the Company or such other place as shall be mutually agreed upon between the Company and the Optionee, a certificate or certificates representing the Shares for which the Option shall have been exercised.

The time of issuance and delivery of the certificate(s) representing the Shares for which the Option shall have been exercised may be postponed by the Company for such period as may be required by the Company, with reasonable diligence, to comply with any applicable listing requirements of any national or regional securities exchange or any law or regulation applicable to the issuance or delivery of such Shares.

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(f) Term and Vesting of Options.

(i) Notwithstanding any other provision of this Plan, (A) no Option shall be granted under this Plan after January 2, 2010, (B) no Option that is intended to be an incentive stock option for purposes of Section 422 of the Code shall be granted under this Plan after ten years from the date on which this Plan was adopted by the Board, and (C) no Option shall be exercisable more than ten (10) years from the date of grant.

(ii) No Option granted to any Optionee shall be treated as an incentive stock option, to the extent such Option would cause the aggregate Fair Market Value (determined as of the date of grant of each such Option) of the Shares with respect to which incentive stock Options are exercisable by such Optionee for the first time during any calendar year to exceed $100,000. For purposes of determining whether an incentive stock Option would cause the aggregate Fair Market Value of the stock to exceed the $100,000 limitation, such incentive stock Options shall be taken into account in the order granted. For purposes of this subsection, incentive stock Options include all incentive stock options under all plans of the Company that are incentive stock option plans within the meaning of Section 422 of the Code.

Except as provided in Section 6(g)(iv), Options granted hereunder shall mature and become exercisable in whole or in part, in accordance with such vesting schedule as the Board shall determine, which schedule shall be stated in the Option Agreement. Options may be exercised in any order elected by the Optionee whether or not the Optionee holds any unexercised Options under this Plan or any other plan of the Company.

(g) Termination of Options.

(i) Unless sooner terminated as provided in this Plan, each Option shall be exercisable for the period of time as shall be determined by the Board and set forth in the Option Agreement, and shall be void and unexercisable thereafter.

(ii) Except as otherwise provided herein or in the Option Agreement, upon the termination of the Optionee's employment or other relationship with the Company for any reason, Options exercisable on the date of termination of employment or such other relationship shall be exercisable by the Optionee (or in the case of the Optionee's death subsequent to termination of employment or such other relationship, by the Optionee's executor(s) or administrator(s)) for a period of three (3) months from the date of the Optionee's termination of employment or such other relationship.

(iii) Except as otherwise provided herein or in the Option Agreement, upon the Disability or death of an Optionee while employed or otherwise engaged by the Company, Options held by such

Optionee which are exercisable on the date of Disability or death shall be exercisable for a period of twelve (12) months commencing on the date of the Optionee's Disability or death, by the Optionee or his legal guardian or, in the case of death, by his executor(s) or administrator(s); provided, however, that if such disabled Optionee shall commence any employment during such one (1) year period with a competitor of the Company (including, but not limited to, full or part-time employment or independent consulting work), as determined solely in the judgment of the Board, all Options held by such Optionee which have not yet been exercised shall terminate immediately upon the commencement thereof.

(iv) Options may be terminated at any time by agreement between the Company and the Optionee.

(h) Forfeiture. Notwithstanding any other provision of this Plan, if the Optionee's employment or engagement is terminated by the Company and the Board makes a determination that the Optionee (i) has engaged in any type of disloyalty to the Company, including without limitation, fraud, embezzlement, theft, or dishonesty in the course of his employment or engagement, or (ii) has been convicted of a felony or (iii) has disclosed any Proprietary Information without the consent of the Company or (iv) has breached the terms of any written confidentiality agreement or any non-competition agreement with the Company in any material respect, all unexercised Options held by such Optionee shall terminate upon the earlier of the date of termination of employment or engagement for "cause" or the date of such a finding.

Section 7. Determination of Fair Market Value of Common Stock.

(a) Except to the extent otherwise provided in this Section 7, the Fair Market Value of a share of Common Stock shall be determined by the Board in its sole discretion.

(b) In the event that Shares are traded in the over-the-counter market, the Fair Market Value of a share of Common Stock shall be the mean of the bid and asked prices for a share of Common Stock on the relevant valuation date as reported in The Wall Street Journal (or, if not so reported, as otherwise reported by the National Association of Securities Dealers Automated Quotation System ("NASDAQ")), as applicable or, if there is no trading on such date, on the next preceding trading date. In the event Shares are listed on a national or regional securities exchange or traded in the NASDAQ National Market System, the Fair Market Value of a share of Common Stock shall be the closing price of a share of Common Stock on the exchange or on NASDAQ/NMS, as reported in The Wall Street Journal on the relevant valuation date, or if there is no trading on that date, on the next preceding trading date.

(c) "Adjusted Fair Market Value" shall mean in the event of a Change of Control, the greater of (A) the highest price per share of Common Stock paid or payable to holders of the Common Stock in any transaction (or series of transactions) constituting or resulting (or as to which approval by shareholders of the Company constitutes or results) in the Change of Control or (B) the highest Fair Market Value of a share of Common Stock on any business day during the ninety (90) day period ending on the date of the Change of Control.

Section 8. Adjustments.

(a) Subject to required action by the shareholders, if any, the number of shares of Common Stock as to which Options may be granted under this Plan and the number of shares subject to outstanding Options and the option prices thereof shall be adjusted proportionately for any increase or decrease in the number of outstanding shares of Common Stock of the Company resulting from stock splits, reverse stock splits, stock dividends, reclassifications and recapitalizations.

(b) No fractional shares of Common Stock shall be issuable on account of any action mentioned in paragraph 8(a) above, and the aggregate number of shares into which Shares then covered by the Option, when changed as the result of such action, shall be reduced to the number of whole shares resulting from such action, unless the Board, in its sole discretion, shall determine to issue scrip

certificates with respect to any fractional shares, which scrip certificates, in such event, shall be in a form and have such terms and conditions as the Board in its discretion shall prescribe.

Section 9. Rights as a Shareholder.

The Optionee shall have no rights as a shareholder of the Company and shall have neither the right to vote nor receive dividends with respect to any Shares subject to an Option until such Option has been exercised.

Section 10. Time of Granting Options.

The date of grant of an Option shall, for all purposes, be the date on which the Board authorizes the granting of such Option. Notice of the grant shall be given to each Participant to whom an Option is so granted within a reasonable time after the date of such grant.

Section 11. Modification, Extension and Renewal of Option.

Subject to the terms and conditions of the Plan, the Board may modify, extend or renew an Option, or accept the surrender of an Option (to the extent not theretofore exercised). Notwithstanding the foregoing, (a) no modification of an Option which adversely affects an Optionee shall be made without the consent of such Optionee, and (b) no incentive stock Option may be modified, extended or renewed if such action would cause it to cease to be an "incentive stock option" under the Code, unless the Optionee specifically acknowledges and consents to the tax consequences of such action.

Section 12. Conditions to Issuance of Shares Upon Exercise.

(a) The obligation of the Company to issue and sell Shares to an Optionee upon the exercise of an Option granted under the Plan is conditioned upon (i) the Company obtaining any required permit or order from appropriate governmental agencies, authorizing the Company to issue and sell such Shares, and (ii) such issuance and sale complying with all relevant provisions of law, including, without limitation, the Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed.

(b) At the option of the Board, the obligation of the Company to issue and sell Shares to an Optionee upon the exercise of an Option granted under the Plan may be conditioned upon obtaining appropriate representations, warranties and agreements of the Optionee set forth in the Stock Purchase Agreement. Among other representations, warranties, restrictions and agreements, the Optionee may be required to represent and agree that the purchase of Shares of Common Stock under the Option Agreement shall be for investment, and not with a view to the public resale or distribution thereof, unless the Shares subject to the Option are registered under the Securities Act and the issuance and sale of the Shares complies with all other laws, rules and regulations applicable thereto. Unless the issuance of such Shares is registered under the Securities Act, the Optionee shall acknowledge that the Shares purchased on exercise of the Option are not registered under the Securities Act and may not be sold or otherwise transferred unless such Shares have been registered under the Securities Act in connection with the sale or other transfer, or counsel satisfactory to the Company has issued an opinion satisfactory to the Company that the sale or other transfer is exempt from registration under the Securities Act, and unless said sale or other transfer is in compliance with any other applicable laws, rules and regulations including all applicable federal and state securities laws, rules and regulations. Unless the Shares subject to an Option are registered under the Securities Act, the certificates representing all Shares issued upon exercise of such Option shall contain the following legend:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED OR ANY APPLICABLE STATE SECURITIES LAWS. THESE SHARES HAVE NOT BEEN ACQUIRED WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, ASSIGNED, EXCHANGED, MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED OR DISPOSED OF, BY GIFT OR OTHERWISE, OR IN ANY WAY ENCUMBERED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SHARES UNDER THE SECURITIES

ACT OF 1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR A SATISFACTORY OPINION OF COUNSEL SATISFACTORY TO PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT AND UNDER APPLICABLE STATE SECURITIES LAWS.

Section 13. Transferability.

No Option shall be assignable or transferable otherwise than by will or by the laws of descent and distribution. During the lifetime of the Optionee, the Optionee's Options shall be exercisable only by such Optionee, or in the event of his or her legal incapacity, then by the Optionee's legal representative.

Section 14. Other Provisions.

The Option Agreement and Stock Purchase Agreement may contain such other provisions as the Board of Directors in its discretion deems advisable and which are not inconsistent with the provisions of this Plan.

Section 15. Change of Control.

(a) For purposes of the Plan, "Option Cancellation Date" shall mean, as to each Option, the later of: (i) the first business day after the expiration of a period of six (6) months from the date of grant of the Option; (ii) in the event of a Change of Control as defined in Section 2(b)(ii)(A) or 2(b)(ii)(B)(2), the date on which the transaction approved by shareholders of the Company (as provided in Section 2(b)(ii)) is consummated; and (iii) in the event of a Change of Control as defined in Section 2(b)(i) or 2(b)(iii), the first business day after the expiration of a period of sixty (60) days after the occurrence of such event.

(b) Upon a Change of Control, all Options (whenever granted) outstanding on the date of such Change of Control shall be or become immediately and fully exercisable.

(c) In the event of a Change of Control as defined in Section 2(b)(i), 2(b)(ii)(A), 2(b)(ii)(B)(2) or 2(b)(iii), all Options (whenever granted) outstanding on the Option Cancellation Date which are not exercised on or before the Option Cancellation Date shall be canceled on such date by the Company, and the Company shall on such date pay to each holder of each such canceled Option a cash amount equal to the excess, if any, in respect of each Option canceled, of (i) the greater of (A) the Fair Market Value of the shares of Common Stock subject to the Option on the business day immediately preceding the Option Cancellation Date or (B) the Adjusted Fair Market Value of the Common Stock subject to the Option over (ii) the aggregate purchase price which would have been payable for such shares of Common Stock pursuant to the Option had the Option not been canceled.

Section 16. Amendment of the Plan.

Insofar as permitted by law and the Plan, the Board may from time to time suspend, terminate or discontinue the Plan or revise or amend it in any respect whatsoever with respect to any Shares at the time not subject to an Option; provided, however, that without approval of the shareholders, no such revision or amendment may change the aggregate number of Shares for which Options may be granted hereunder, change the designation of the class of employees eligible to receive Options or decrease the price at which Options may be granted.

Any other provision of this Section 16 notwithstanding, the Board specifically is authorized to adopt any amendment to this Plan deemed by the Board to be necessary or advisable to assure that the incentive stock Options or the non-qualified stock Options available under the Plan continue to be treated as such, respectively, under the law.

Section 17. Application of Funds.

The proceeds received by the Company from the sale of shares pursuant to the exercise of Options shall be used for general corporate purposes or such other purpose as may be determined by the Company.

Section 18. No Obligation to Exercise Option.

The granting of an Option shall impose no obligation upon the Optionee to exercise such Option.

Section 19. Reservation of Shares.

The Company, during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

The Company, during the term of this Plan, shall use its best efforts to seek to obtain from appropriate regulatory agencies any requisite authorization in order to issue and sell such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The inability of the Company to obtain from any such regulatory agency having jurisdiction the requisite authorization(s) deemed by the Company's counsel to be necessary for the lawful issuance and sale of any Shares hereunder, or the inability of the Company to confirm to its satisfaction that any issuance and sale of any Shares hereunder will meet applicable legal requirements, shall relieve the Company of any liability in respect to the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

Section 20. Taxes, Fees, Expenses and Withholding of Taxes.

(a) The Company shall pay all original issue and transfer taxes (but not income taxes, if any) with respect to the grant of Options and/or the issue and transfer of Shares pursuant to the exercise thereof, and all other fees and expenses necessarily incurred by the Company in connection therewith, and will from time to time use its best efforts to comply with all laws and regulations which, in the opinion of counsel for the Company, shall be applicable thereto.

(b) The grant of Options hereunder and the issuance of Shares pursuant to the exercise thereof is conditioned upon the Company's reservation of the right to withhold in accordance with any applicable law, from any compensation or other amounts payable to the Optionee, any taxes required to be withheld under federal, state or local law as a result of the grant or exercise of such Option or the sale of the Shares issued upon exercise thereof. To the extent that compensation or other amounts, if any, payable to the Optionee is insufficient to pay any taxes required to be so withheld, the Company may, in its sole discretion, require the Optionee, as a condition of the exercise of an Option, to pay in cash to the Company an amount sufficient to cover such tax liability or otherwise to make adequate provision for the Company's satisfaction of its withholding obligations under federal, state and local law.

Section 21. Notices.

Any notice to be given to the Company pursuant to the provisions of this Plan shall be addressed to the Company in care of its Secretary (or such other person as the Company may designate from time to time) at its principal executive office, and any notice to be given to an Optionee shall be delivered personally or addressed to him or her at the address given beneath his or her signature on his or her Option Agreement, or at such other address as such Participant or his or her transferee (upon the transfer of the Shares purchased upon exercise) may hereafter designate in writing to the Company. Any such notice shall be deemed duly given when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, registered or certified, and deposited, postage and registry or certification fee prepaid, in a post office or branch post office regularly maintained by the United States Postal Service. It shall be the obligation of each Optionee and each transferee holding Shares purchased upon exercise of an Option to provide the Secretary of the Company, by letter mailed as provided herein, with written notice of his or her direct mailing address.

Section 22. No Enlargement of Optionee Rights.

This Plan is purely voluntary on the part of the Company, and the continuance of the Plan shall not be deemed to constitute a contract between the Company and any Optionee, or to be consideration for or a condition of the employment or service of any Optionee. Nothing contained in this Plan shall be deemed to give any Optionee the right to be retained in the employ or service of the Company or

any Subsidiary, or to interfere with the right of the Company or any such corporation to discharge or retire any Optionee thereof at any time, subject to applicable law. No Optionee shall have any right to or interest in Options authorized hereunder prior to the grant thereof to such Optionee, and upon such grant he shall have only such rights and interests as are expressly provided herein, subject, however, to all applicable provisions of the Company's Certificate of Incorporation, as the same may be amended from time to time.

Section 23. Invalid Provisions.

In the event that any provision of this Plan is found to be invalid or otherwise unenforceable under any applicable law, such invalidity or unenforceability shall not be construed as rendering any other provisions contained herein as invalid or unenforceable, and all such other provisions shall be given full force and effect to the same extent as though the invalid or unenforceable provision was not contained herein.

Section 24. Applicable Law.

This Plan shall be governed by and construed in accordance with the laws of the State of Delaware.

Section 25. Effective Date.

This Plan shall become effective on the date that it is adopted by the Board; provided, however, that it shall not be an incentive stock option plan if it is not approved, within one year (365 days) of its adoption by the Board, by a majority of the votes cast at a duly held shareholder meeting at which a quorum representing a majority of Company's outstanding voting shares is present, either in person or by proxy. The Board may make grant Options hereunder prior to approval of the Plan or approval of any material amendment thereto; provided, however, that any and all incentive stock Options so granted automatically shall be converted into non-qualified stock Options if the Plan or any material amendment is not approved by shareholders within 365 days of its adoption.
