Operator:             Good morning. My name is (Marcia) and I will be your
                      conference facilitator today. At this time, I would like
                      to welcome everyone to the Motient Investor Conference
                      Call. All lines have been placed on mute to prevent any
                      background noise. If you have a question at any time
                      during the call, simply press star, then the number 1 on
                      your telephone keypad. If you would like to withdraw your
                      question, press the pound key. Thank you. Mr. Downie, you
                      may begin your conference.

Chris Downie:         Thank you. Good morning. My name is Chris Downie and I
                      am the Executive Vice President and COO of Motient
                      Corporation. First off, thank you for joining me, Robert
                      Macklin, our General Counsel, and (Jared) Abbruzzese, a
                      representative from Communications Technology Advisors,
                      our chief restructuring entity on this call. Before I get
                      into any details, I will ask (Rob) to get a few of the
                      preliminaries out of the way.

Robert Macklin:       Thanks Chris. For those of you who may be listening,
                      please be aware that with the exception of any historical
                      information that we may discuss, some of our statements
                      may be forward-looking statements that involve risk and
                      uncertainties that cause our actual results to differ
                      materially from our statements today. In addition, we will
                      be limiting our remarks to information previously
                      disclosed in our public filings with the SEC.

                      We will also be releasing a transcript of this call
                      immediately after its conclusion, so please be aware that
                      your questions may be transcribed for public release.
                      Chris will briefly discuss several matters, after which we
                      will hold a question and answer session, which again will
                      be limited to matters and information previously disclosed
                      in our public filings.

                                       1


Chris Downie:         Thanks (Rob). As you are all aware, Motient is a
                      nationwide provider of two-way wireless mobile data
                      services and mobile Internet services. Our customers use
                      our network and applications for email messaging and
                      enterprise data communication services. Our network is
                      designed to offer a broad array of wireless data services
                      such as two-way mobile Internet services, telemetry
                      systems, and mobile data and fleet management systems.

                      As of June 15, 2004, our network covers a geographic area
                      populated by more than 225 million people, and it's
                      comprised of over 1,200 base stations that provide service
                      to 475 of the nation's largest cities and towns. As of
                      March 31, 2004, there were approximately 194,000 user
                      devices registered on our network and approximately
                      108,000 user devices with active usage on our network.

                      In addition to selling messaging services that use our own
                      network, we are a national premier dealer for T-Mobile
                      USA, and an authorized agent for Verizon Wireless. Under
                      our agreements with these providers, we sell nationwide
                      network subscriptions for T-Mobile and Verizon. These
                      agreements allow us to sell and promote wireless email and
                      wireless Internet applications to enterprise accounts on
                      accounts with greater capacity and speed than our own, and
                      that are voice capable.

                      In addition to our operating business, we also currently
                      own a 29.5% interest in Mobile Satellite Ventures LP, or
                      MSV, a mobile satellite services provider, assuming the
                      conversion of all outstanding convertible notes. For more
                      information on these aspects of our business, please
                      consult our public filings with the SEC, such as our Form
                      10Q for the quarter ended March 31, 2004, which was filed
                      on July 2, 2004.

                      As a matter of fact, when we filed the Form 10Q on July 2,
                      we became current in our filing obligations under the
                      Securities Exchange Act of 1934, for the first time since
                      shortly after we emerged from bankruptcy in May of 2002.
                      As we have previously discussed in our SEC filings, we
                      fell behind in our reporting under the Exchange Act
                      because of a disagreement with our previous auditors over
                      the accounting treatment of some transactions that
                      occurred in 2000 and 2001. By the time we had resolved
                      those accounting issues, we were about a year behind in
                      our reporting.

                      These last few months we've caught up, and with the filing
                      of our First Quarter 2004 10Q on July 2, we are now
                      current. Management, of course, intends to remain current
                      in our Exchange Act reporting obligations in the future.
                      If you want all the details regarding these accounting
                      matters, please see our 10K for the year ended December
                      31, 2002, filed in March of this year.

                      Right after we filed the 10Q on July 2, we also filed two
                      registration statements, one on Form S8 and one on Form
                      S1. We filed the S8 to register some shares that had been
                      issued to employees who exercised employee stock options.
                      These shares were registered because they had been issued
                      when we weren't current with our Exchange Act reporting,
                      and therefore we had to issue these shares as restricted
                      shares at that time.

                      As for the S1, which the SEC declared effective on July
                      13, or yesterday, we filed it in order to register shares
                      that we had issued in previous transactions, mainly to
                      private placements of our common stock in April and July


                                       3


                      of this year, and some other shares that were otherwise
                      restricted in some way. The S1 also registers common stock
                      that may be issued in the future if the holders of certain
                      warrants that we issued in the past decide to exercise
                      their warrants.

                      For the most part, these shares had contractual
                      registration rights of one form or another that required
                      us to register them. Since we couldn't file a registration
                      statement for these shares and warrants during the period
                      we weren't current in our SEC reporting, we had a little
                      over 15 million shares that needed to be registered.
                      Typically, a registration such as this would be done on a
                      Form S3 and not on an S1, but since we're current in our -
                      since we weren't current in our SEC reporting, we had to
                      file the S1 rather than the more customary S3.

                      What this S1 does is to register the shares owned by the
                      stockholders listed in the S1. To be clear, Motient is not
                      using the S1 as a vehicle to issue new shares. We're
                      merely registering shares that we had already issued, up
                      to and including the shares issued in the July 1 private
                      placement. The holders of these shares may or may not
                      choose to sell their shares, but the choice is theirs and
                      theirs alone. We have no control over that decision.

                      Among the shares being registered on the S1 are the shares
                      that we issued in a private placement on July 1 of this
                      year. In that placement, the investors purchased 3.5
                      million shares of Motient's common stock at a price of
                      $8.57 per share, yielding gross proceeds of about $30
                      million. This price per share represented a 15% discount
                      to the closing price of our stock the day before we signed
                      a heavily negotiated letter of intent with the investors.
                      Since the letter of intent was signed on June 25 and the
                      stock had closed at $10.09 on June 24, the private
                      placement closed at $8.50 per share. If you're interested
                      in learning more about this transaction, please see our
                      quarterly report on Form 10Q for the quarter ended March
                      31, 2004, again filed on July 2, 2004.

                      If you take a look at that 10Q, you'll also see that we're
                      working hard to preserve our cash by cutting costs and
                      maximizing operational efficiency. We're also working to
                      pay down debt to reduce interest expense. In that vein, we
                      have taken some specific actions that I'll describe
                      briefly here, but that are described more fully in the 10Q
                      as well as our other SEC filings. The details of these
                      cost-cutting measures are more extensive than I have time
                      to describe here, so please make sure you read our SEC
                      filings, as they present a more complete picture of our
                      cost-cutting actions than I can give you in the limited
                      time I have on this call.

                      In February of 2004, we eliminated about 1/3 of our
                      workforce and reduced employee and related expenditures by
                      about $400,000 per month. We also settled some of our
                      vendor obligations, such as our obligations with Motorola
                      and Hewlett Packard. The full amount due and owing under
                      these agreements was a combined $6.8 million, but we were
                      able to satisfy these obligations by paying a combined
                      $3.9 million in cash and issuing a warrant to Motorola to
                      purchase 200,000 shares of our common stock at a price of
                      $8.68 per share.

                      As part of the Hewlett Packard deal, we were able to
                      cancel and retain the funds from a $1.1 million letter of
                      credit that collateralized the capital lease for the
                      benefit of Hewlett Packard.

                      We are also in the process of assessing our wireless data
                      network to reduce network operating costs. This
                      rationalization, as we call it, encompasses among other
                      things reducing unneeded capacity by deconstructing
                      underutilized and unprofitable base stations and
                      deconstructing base stations that pass an immaterial
                      amount of customer data traffic. In some cases, these base
                      stations were originally constructed specifically to serve
                      customers with nationwide requirements that are no longer
                      customers.

                                       5


                      Additionally, we have recently asked the FCC to relocate
                      Motient into the so-called upper 800-megahertz band as
                      part of the 800-megahertz rebanding effort known as the
                      Consensus Plan. This would group the frequencies that
                      Motient uses to operate its wireless data network next to
                      other commercial providers in the 800-megahertz band.

                      Finally, I just wanted to note that we're currently listed
                      on the pink sheets under the symbol MNCP. Now that we are
                      current with our financial reporting, we may be eligible
                      to be listed on a national stock exchange of some sort,
                      such as NASDAQ or the American Stock Exchange, but for the
                      time being the company hasn't made any decisions in this
                      regard. We will, of course, make a public announcement if
                      or when we should decide to become listed.

                      At this point, I'd like to open the floor up to any
                      questions that you may have. Please give your questions to
                      the operator, if you have not already done so, and we will
                      attempt to answer the questions if it - if appropriate.

                      We're receiving the questions on another line, so if you
                      don't mind holding, we will address the questions as soon
                      as they get relayed to us.

(Connie):             I have a question. The question is from Ethan Swartz from
                      CRT Capital. And the first question is, what is the
                      timeframe for construction of the ATC network?

Robert Macklin:       Okay.

                                       6


(Connie):             And the second question is, is the company in direct
                      negotiations with Inmarsat?

Chris Downie:         There's a question from (Ethan Schwartz) from CRT. The
                      question was -what is the timeframe for ATC construction,
                      and the second question was - is the company in direct
                      negotiations with Inmarsat. I will ask (Jerry) Abbruzzese
                      to answer that question, just keep in mind that the
                      company has 29.5% interest in MSV and MSV is a private
                      company, so we will try if possible to address that
                      question, but we might not be able to. (Jerry)?

J Abbruzzese:         The first one regarding ATC, which is the ancillary
                      terrestrial component construction, we understand MSV has
                      gone back to the FCC and asked for some additional changes
                      to the authorization which MSV feels will make it more
                      compatible with other potential strategic entities.

                      And from an operational perspective the authorization and
                      the regulation that has been issued by the FCC so far does
                      make MSV or that whole ATC a viable commercial product,
                      but it's now is the question of degrees and capabilities.

                      The current plan for MSV is to continue to pursue expanded
                      capabilities with the FCC all the while meeting its
                      requirements and build requirements that the FCC has laid
                      out for it. And I really don't want to go too much beyond
                      that. As (Chris) reminded everybody, it's a private
                      company and we are not looking to talk on behalf of that
                      company, merely discussing what is out in the public
                      domain currently.

                      Regarding Inmarsat, Inmarsat is currently an important
                      entity. They have spectrum that is adjacent to MSV and
                      there are wide ranging discussions that have been going on
                      with all parties related to ATC and the satellite spectrum
                      that is contiguous to MSV. So I hope that answers the
                      question without getting into something that we shouldn't
                      be talking about.

Chris Downie:         Okay. This is Chris again. The second question we
                      received is that - will any of the proceeds that we have
                      raised in the recent equity transactions be used to make
                      investments in MSV. There are, you know, no plans or
                      decisions at this juncture with regards to using those
                      proceeds for those investments. Obviously if that changes
                      we will make public announcements accordingly.

J Abbruzzese:         Chris, are we waiting for other questions?

Chris Downie:         Yes, we're getting questions on another line right now.
                      Thanks for everybody's patience.

                      We have a couple of additional questions. The first
                      question relates to our cash run rate now, at the
                      beginning of the year and a year ago. Given some of the
                      complexities in that answer, I'm simply going to point
                      that person to our public filings. I'm not going to be
                      able to provide any more details with regards to the
                      current cash run rate outside of our public financials.

                      The second question, are there plans to reduce our Rare
                      and CSFB data obligations with the proceeds from this
                      transaction? As we stated in our press release that we
                      issued on July 2, there is an intention to use proceeds
                      from this transaction to reduce corporate debt. Any
                      specific decisions with regards to Rare and CSFB are still
                      under consideration and we'll make announcements in that
                      regard as soon as appropriate.

                                       8


Robert Macklin:       Chris, this is (Rob). We have another question
                      regarding the intents of plans in the 800 megahertz
                      rebanding efforts. As we've indicated in our public
                      filings, we've requested rebanding into the so-called
                      upper 800 part of the 800 megahertz band next to other
                      commercial providers.

                      The FCC has not issued any sort of final order on that.
                      The FCC publicly issued a summary plan and an order
                      adopting the broad strokes of the consensus plan. However,
                      no specifics as they relate to Motient have yet been
                      issued. We will of course announce publicly what will
                      happen if and when we actually do get any specifics on
                      that matter.

Chris Downie:         We have time for probably a couple more questions. We're
                      in the process of getting them on another line here.
                      Again, thanks for your continued patience.

                      Our next question is - do we have any 800-megahertz
                      frequencis currently up for sale? There have been no
                      announcements with regards to additional frequencies for
                      sale. We will make appropriate announcements in that
                      regard to the extent that additional frequency sales
                      arise.

                      My apologies. We're experiencing some technical
                      difficulties getting some of the questions in here. Given
                      the time, we're going to probably just try to answer one
                      more question to the extent that we can get it in here. I
                      apologize for this delay and thank you for your patience.

                      We have one last question. Again, I apologize for the
                      delay. The question is - is there any additional need for
                      outside investment in MSV and if so would Motient
                      co-invest to - in order not to be diluted in this
                      investment? As we said earlier, unfortunately MSV is a
                      private company so we're limited in our ability to comment
                      on anything related to them that hasn't been publicly
                      disclosed.

                      I'm not exactly sure if Jerry could like to comment,
                      (Jerry).

J Abbruzzese:         Let me answer, Chris. Clearly, the authorizations as
                      granted by the FCC contemplate the construction and
                      launching of satellites at some point in the future. MSV
                      currently has two satellites that are operational. Both
                      satellites have a period of life left in them that, you
                      know, is substantial.

                      So I think one could appreciate that at some point in time
                      there will be a necessity for MSV to raise additional
                      capital simply because it's in the business that is
                      somewhat capital intensive. As to the timing of that and
                      the scope of that, that will be determined by the MSV
                      board as they progress.

                      One of the advantages that MSV does have in the space it's
                      in, it does have two satellites operational today which
                      under the rule of the FCC are a requirement for being
                      licensed, that you have to have satellites launched. And
                      so I do think, you know, that is a good thing with regards
                      to MSV.

                      And, you know Chris, I know this is the last question so I
                      wanted to make a quick statement as an advisor to the
                      Company. Everybody should be very clear that this
                      management and this Company, Motient, is extraordinarily
                      focused on maximizing its operational efficiencies. To
                      that regard, it's constantly reviewing its cost-cutting
                      efforts and its operational efficiencies and its portfolio
                      of assets and how best to maximize the value of those
                      assets.

                      In that regard, clearly one of the biggest assets and the
                      most important asset of the Company arguably could - would
                      be its holdings in MSV and in that regard, Motient is a
                      very active, you know, representative and owner of MSV and
                      very involved in ensuring that MSV goes forward and
                      provides the maximum return possible for all of the
                      stakeholders of Motient.

                      I just want to make sure everybody understands clearly
                      that's a high priority and high focus of all of us that
                      are involved in the Company.

Chris Downie:         Thanks, (Jerry). Again, thanks for everybody's patience
                      on this call. My apologies for the technical difficulties.
                      We'll try and do it better next time and just hope
                      everybody has a great day. Thank you.

Operator:             This concludes today's conference call. You may now
                      disconnect.
