         Issuer, a copy of which is attached to an earlier version of this
         Schedule 13D as Exhibit 99.22 (the "August 2007 Motion for Temporary
         Restraining Order"). On September 5, 2007, Director Hamot sent an email
         to certain members of the Board of Directors of the Issuer, a copy of
         which is attached as Exhibit 99.25 (the "9/5/07-A Email"), having
         attached to it a Preliminary Injunction issued on August 28, 2007 (the
         "August 2007 Preliminary Injunction") from which the August 2007 Motion
         for Temporary Restraining Order was converted. The August 2007
         Preliminary Injunction ordered that the Issuer respond to all
         reasonable requests by Messrs. Hamot and Siegel for information
         pertinent and necessary to perform their duties as members of the Board
         of Directors of the Issuer. The Court did not alter the status of a
         related stipulation and protective order, as discussed in the August
         2007 Preliminary Injunction.

         In connection with his service as a Class D Director of the Issuer, Mr.
         Hamot delivered a letter to Director Bailey of the Issuer concerning
         the independence of Director Bailey, Chairman of the Issuer's
         independent Audit Committee and formerly the CEO of Viisage Technology
         Inc., a copy of which is attached to an earlier version of this
         Schedule 13D as Exhibit 99.24.

         On September 5, 2007, Director Harris responded via email to Director
         Hamot's specific concerns about Director Bailey's independence and his
         role on the Audit Committee (the "9/5/07-B Email").

                                                                    Page 8 of 19

         On September 7, 2007, in further commenting on the independence of
         Director Bailey, Director Hamot replied to the 9/5/07-B Email, copying
         certain members of the Board of Directors of the Issuer and containing
         certain attachments, a copy of which (without the attachments thereto)
         is attached as Exhibit 99.26 (the "9/7/07 Email"). Director Hamot's
         reply also addressed the recent filing of the Issuer's non-compliant
         Form 10-Q for the quarter ended June 30, 2007 in violation of
         Regulation S-X.

         As of the date of this Amendment No. 19, except as set forth above, and
         in the 9/5/07-A Email and the 9/7/07 Email, including any attachments
         thereto, and as otherwise set forth in the Schedule, none of the Costa
         Brava Reporting Persons has any present plans or intentions which would
         result in or relate to any of the transactions described in
         subparagraphs (a) through (j) of Item 4 of the instructions to Schedule
         13D.

                                  Exhibit 99.25

          Email dated September 5, 2007 from Director Hamot to certain
                members of the Board of Directors of the Issuer

Attached you will find a court order issued on August 28th. You'll note that my
request for a Temporary Restraining Order has been granted and converted to a
Preliminary Injunction preventing the Corporation's continued refusal to remit
to me the documents necessary for me to perform my duties as a director.

As of this morning, Telos has not provided any of the requested minutes of the
Audit Committee meetings for the periods since Director Bailey became Chair
thirteen months ago. Additionally, Telos has provided no further details of
Director Bailey's "independence" as specified in NASD Rule 4200 (a) (15). You
will recall that I requested such during the August 9th 2007 telephonic Board of
Directors meeting. As you are aware, having received no further evidence of
Director Bailey's independence, on August 18, 2007 I sent an email specifying my
exact concerns with Director Bailey's past employment and his position on the
Audit Committee.

Hence, now several months have past since my request for Audit Committee minutes
and significantly important ones have still not been provided. Similarly, almost
a month has past since I questioned Bailey's independence, and not a single
effort has been made to detail how this determination was made. At this juncture
I must insist that the Board hire independent counsel to review Director
Bailey's independence and discuss such with the NASD if necessary. If he is
found to lack such, I would expect that Telos would have to notify the SEC that
the 10Q's of 2006's third and forth quarter, 2007's first and second quarter,
and the 10K of 2006, were not reviewed and approved by an independent audit
committee as mandated for public companies in the Sarbanes-Oxley Act.

                                                                   Page 14 of 19

with their duties as directors and in preparation for a telephonic board meeting
scheduled for August 9, 2007.

         The Court, having conducted a hearing in open court with respect to
this motion and having heard the arguments of counsel on August 27, 2007, will
convert the present motion to a request for preliminary injunction in order to
avoid the durational limitations contained in Md. Rule 15 504(c) with respect to
temporary restraining orders and grant plaintiffs' motion for a preliminary
injunction, the Court being satisfied that the four factors set forth in
Eastside Vend Distributers., Inc. v. Pepsi Bottling Group, Inc., 396 Md. 219,
240 (2006) (citing Dept. of Transportation v. Armacost, 299 Md. 392, 404 (1984))
weigh in favor of its issuance.

         It is, therefore, this 28th day of August, 2007, by the Circuit Court
for Baltimore City, Part 20, ORDERED as follows:

         1.       Telos shall promptly respond to all reasonable requests by
                  plaintiffs for information pertinent and necessary to perform
                  their duties as members of the Board of Directors of defendant
                  corporation.

         2.       Telos shall provide plaintiffs with all information given to
                  other members of its Board of Directors at the same time that
                  said information is provided to the other directors.

         3.       Telos shall be permitted to withhold from plaintiffs
                  information protected by the work product doctrine or
                  attorney/client privilege in connection with the ongoing
                  litigation in Costa Brava Partnership III, L.P., et al. v.
                  Telos Corporation, et al. (Civil Case No. 24-C-05-009296)
                  pending before the Circuit Court for Baltimore City, Part 20.

         4.       Plaintiffs Hamot and Siegel are shareholder plaintiffs in the
                  above captioned litigation. On July 7, 2006, these plaintiffs,
                  by their counsel, Harry Levy, Esquire and Lewis T. Stevens,


                                                                   Page 15 of 19

                  Esquire, executed a Stipulation and Protective Order pursuant
                  to which Telos is entitled to designate documents produced in
                  discovery or submitted to the Court as "confidential" or
                  "highly confidential," given a good faith belief that the
                  material satisfies those definitions as set forth in the
                  Stipulation and Protective Order. "Highly confidential"
                  material is defined as confidential material that is so
                  sensitive that any disclosure beyond disclosure to those
                  individuals specified in paragraph III (D) below (chiefly,
                  counsel of record, other counsel for the parties, the Court
                  and consultants, experts and outside litigation support
                  personnel) deliberately or inadvertently, would cause
                  significant competitive or other injury. Since being elected
                  to the Board of Directors of Telos Corporation on June 18,
                  2007, plaintiffs have sought documents from Telos which were,
                  or may be designated, as "highly confidential," claiming that
                  they are no longer bound by the limitations imposed by the
                  Stipulation and Protective Order due to their status as board
                  members and fiduciaries of the defendant corporation. Telos'
                  resistance to such claims resulted in the present lawsuit.
                  When counsel for plaintiffs was asked at oral argument to
                  express his clients' objections to abiding by the limitations
                  imposed by the Stipulation and Protective Order, he indicated
                  to the Court that it was based upon their understanding of
                  their status under Delaware corporate law, citing Henshaw v.
                  American Cement Corp., 252 A.2d 125 (Del. Ch. 1969). To be
                  certain, Henshaw stands for the proposition that, as a matter
                  of common law, a director of a Delaware corporation has the
                  right to inspect corporate books and records and that right is
                  correlative to his duty to protect and preserve the
                  corporation. Id. at 128. The premise is clearly that directors


                                                                   Page 16 of 19

                  are fiduciaries with duties to the corporation and its
                  shareholders and are subject to claims for any violation of
                  those duties. According to plaintiffs here, that is the end of
                  the story. Interestingly, however, Mr. Henshaw sought to
                  engage agents and attorneys to assist him in his inspection of
                  corporate books and records. These same individuals were
                  embroiled in pending litigation against the corporation and
                  the Chancery Court had to determine whether Henshaw's director
                  status gave him the unlimited right to retain agents and
                  attorneys of his own choosing. The court said no, recognizing
                  the corporation's legitimate interest in protecting its
                  position in the lawsuit. It characterized the effort as "back
                  door discovery unbound by work product, privilege, or any
                  other limitation upon discovery." Id. at 130.

                  While the issue here is not identical to that addressed in
                  Henshaw, the principle is the same. During the pendency of the
                  shareholder litigation against Telos, this Court is not
                  inclined to permit Messrs. Hamot and Siegel to avoid their
                  commitments under the Stipulation and Protective Order through
                  the guise of their newly acquired director status. Upon
                  resolution of the shareholder litigation, the Court's
                  determination of this issue may be quite different. But that
                  is a matter for another day. Accordingly, the Court will
                  consider plaintiffs in this action bound by the terms of the
                  Stipulation and Protective order entered in the shareholder
                  litigation.

         5.       Plaintiffs shall be excused from the requirement of filing a
                  bond in connection with this preliminary injunction.

                                                                   Page 17 of 19

         6.       This preliminary injunction shall remain in effect pending the
                  resolution of the present litigation or until further order of
                  this Court.

                                  Exhibit 99.26

  Email dated September 7, 2007 from Director Hamot to Director Harris, copying
             certain members of the Board of Directors of the Issuer

Sir,

I concur with your desire to do an assessment of Director Bailey's
"independence" pursuant to Rule 4200(a) (15) of the NASD.

I have proposed this "assessment" be done by independent counsel well versed in
these matters. The usual route for investigations at public companies is to have
the Audit Committee supervise such with the assistance of qualified outside
counsel, as the "audit" function relates not only to financial statements but to
issues of corporate control also. In this instance, such a procedure would not
be possible, as the topic of our concerns is itself the independence of the
Audit Committee Chairman.

I have been a part of such an investigation recently. You will find the
following language in the first quarter 10Q of Bradley Pharmaceuticals Inc., of
which I am Interim Chairman and serve on the Audit Committee:

         In response to a resignation letter sent to members of the Board of
Directors on April 13, 2007, from an employee of the Company, the Audit
Committee, with the assistance of its outside counsel, conducted an internal
review of the matters set forth in the letter. The Audit Committee's review was
completed on May 8, 2007, and the results of that review were reported to the
full Board of Directors, the SEC and the Company's independent accountants. No
matters from the review affected the financial statements or books and records
of the Company.


Furthermore, here is a link allowing one to download the Sarbanes-Oxley Act of
2002. http://www.law.uc.edu/CCL/SOact/toc.html. As you'll see, it is a
complicated statute. The retention and use of a renowned national law firm, well
staffed with former senior officials of the SEC who are experienced in
compliance with the Act, would ensure that the assessment that we seek is not
merely adequate, but thorough and unequivocal. Such a skill set is missing from
Telos, obviously.

Furthermore, as you are already aware from my email to Director Bailey on the
morning of August 20, 2007, Telos is already out of compliance with SEC
Regulation S-X, "Form and Content of Financial Statements." As I stated at that
time, below is section 10-01 (d) of this regulation:

"(d) Interim review by independent public accountant. Prior to filing, interim
financial statements included in quarterly reports on Form 10-Q must be reviewed
by an independent public accountant using professional standards and procedures
for conducting such reviews, as established by generally accepted auditing
standards, as may be modified or supplemented by the Commission. If, in any
filing, the company states that interim financial statements have been reviewed
by an independent public accountant, a report of the accountant on the review
must be filed with the interim financial statements."

The filing of the Telos 10Q in the afternoon of August 20, 2007 is an
intentional violation of federal securities Regulation S-X because Telos does
not have "an independent public accountant" at the moment. I have never seen
such an intentional violation of U.S. securities laws in my investing career,
and I read several hundred financial filings each year. Well-advised firms
facing the same issues as Telos - the lack of a public auditor - instead issue
press releases detailing their financial results with many disclaimers, and
follow up with 8K filings of such with the SEC. If you would like more clarity
about this matter please give me a call and I will take you through several
examples.

Instead, at Telos management and Director Bailey are attempting to confuse (a)
the investing public, (b) the SEC, and (c) our firm's creditors into believing
that we are a current filer with the SEC. Simply stated, Telos is not a current
filer. Moreover, by allowing this type of scam to happen when the Board knows it


                                                                   Page 19 of 19

is illegitimate, the Board is encouraging such behavior as opposed to curtailing
it, and we, as directors of a public company, are likely breaching our duty and
loyalty to Telos Corporation.

For your further reference, I have included our company's Audit Committee
charter. Among the many responsibilities of the Audit Committee, I would like to
draw your attention to the fact that the Board has delegated that the Audit
Committee shall "review the effectiveness of the system for monitoring
compliance with laws and regulations...." Clearly, the intentional violation of
federal securities laws (Regulation S-X) by Telos grossly contravenes this
charter.

Since the public disclosure record is clear that Mr. Bailey's company received
very substantial payments from Telos, I must insist at this point that the Board
hire independent counsel to address Mr. Bailey's independence. If you or any
other director copied on this email concur or disagree, please state so
expeditiously. I have included these public disclosures again for your
reference.
