PARIS โ€” Two Loral shareholders are seeking to block the companyโ€™s proposed sale of $300 million in preferred stock to Loralโ€™s principal owner, saying the transaction is a โ€œsweetheart dealโ€ negotiated with insider information not available to other potential buyers.

In a letter sent Oct. 25 to the board of directors of New York-based Loral Space and Communications Inc., shareholder Murray Capital Management Inc. of New York backs many of the criticisms leveled a day earlier by Highland Capital of Dallas.

Murray and Highland Capital are pressuring the board to scrap its agreement to sell $300 million in preferred stock to MHR Fund Management LLC, which owns 36 percent of Loralโ€™s common stock and three of eight seats on the board . If the transaction closes, MHR will have a fourth seat on the board.

In an apparent response to the complaint from Murray and Highland Capital, Loral announced Oct. 27 that it has asked MHR โ€œto consider offering an alternativeโ€ to the proposed $300 million equity financing that would include โ€œall interested shareholders.โ€

Murray and Highland say the Loral-MHR deal was crafted to benefit MHR, not Loralโ€™s shareholders, and that ultimately it will give MHR full control of the company and a possible means of vetoing a future sale of Loral.

Loral spokesman John McCarthy said the company would have no comment on the shareholder protests. In an Oct. 17 announcement, Loral said the MHR preferred-stock sale was approved by โ€œindependent directorsโ€ and โ€œdisinterested members of the Loral board.โ€

Murray and Highland dispute this. Marti P. Murray, president of Murray Capital, says in his Oct. 25 letter that Loralโ€™s board is already stacked in favor of MHR. In addition to MHRโ€™s three selected members โ€” including MHR founder Mark H. Rachesky โ€” the board includes Loral managers, a Loral consultant and others whose relationship to MHR casts doubt on their independence, the letter says .

โ€œWith all due respect, upon close examination, it would seem almost impossible that any such โ€˜independentโ€™ committee of your eight-person board could exist,โ€ Murray says in his letter.

The Highland and Murray protests also question the terms of the Loral-MHR transaction, saying Loralโ€™s recent turnaround nearly a year after emerging from Chapter 11 bankruptcy has increased the companyโ€™s value but is not reflected in the preferred-stock conversion price.

Murray says in his letter that he contacted Loral management after the MHR preferred-stock announcement and learned that โ€œthere is currently no specific transaction agreed to for which Loral would need $300 million in financing.โ€

The Highland and Murray protests reflect a view that Loral, after having spent several years in bad shape, is poised to deliver a payoff to shareholders in one way or another โ€” a sale of its satellite manufacturing or satellite-services division, a purchase of another satellite operator, or internal growth as it develops the business.

โ€œNow that we may be on the cusp of a bright future, we find the board entering into a transaction that will effectively snatch a great deal of our upside away from us and deliver it to MHR,โ€ the Murray letter says.
