Re:      Telos Corporation
         -----------------


Dear Mr. __________,

We represent Costa Brava Partnership III, L.P. ("CBIII"), with regard to their
ownership of certain instruments denominated "12% Cumulative Exchangeable
Redeemable Preferred Stock" ("ERPS") of Telos Corporation ("Telos"). Our client
filed a lawsuit against you entitled Costa Brava Partnership III, L.P. v. Telos
Corporation et al. in the Circuit Court for Baltimore City, Cause No.
24-C--05-009296.

As part of our client's investigation into Telos' recent and historical
financial disclosures, CBIII retained the services of an independent accounting
firm to review Telos' filings with the Securities Exchange Commission ("SEC").
Their investigation--still in its early stages--has so far revealed two
significant material misstatements in Telos' filings with the SEC, leading to
one inexorable conclusion:.

Telos has made and continues to make material misstatements in its public
disclosures.

Accordingly, CBIII demands that you take immediate steps, discussed in detail
below, to investigate Telos' accounting procedures, its relationship with its
auditors Goodman & Company, LLP ("Goodman") and the actions of Telos' Chief
Executive Officer John B. Wood and Chief Financial Officer Michele Nakazawa,
whose signatures certified Telos' materially misstated SEC filings.

I. Material misstatement of ERPS dividend accrual

For the fiscal years of 1992 through 1994, and for the dividend payable June 1,
1995, Telos accrued undeclared dividends on the ERPS in the form of additional
shares of the ERPS. During these periods, more than 1.5 million undistributed
dividends accrued on the ERPS in the form of additional shares of ERPS. Telos'
financial statements filed with the SEC wrongfully do not account for these
additional undistributed shares of ERPS at their current mandatory redemption
value at $10 per share. Furthermore, Telos' financials wrongfully fail to
account for the accrual of mandatory dividends on these undistributed ERPS
shares.

The reported value of the ERPS on Telos' current balance sheet thus materially
understates the mandatory financial obligation of the ERPS by more than $30
million.

To satisfy its obligations under both Generally Accepted Accounting Principles
("GAAP") and Generally Accepted Auditing Standards ("GAAS"), Telos should have
fully disclosed these undistributed shares. If properly accrued and presented in

                                                                   Page 13 of 29

Telos' financial statements, the liability should have included: (1) the issue
price of the ERPS shares; (2) the accretion necessary to amortize the difference
between the issue price and the redemption price over the period of time from
issuance to the stated maturity dates; (3) the issue price of the declared stock
dividends; (4) the related accretion; (5) the issue price of the stock dividends
that would have been declared had Telos done so in lieu of the cash dividends
that it did not pay; and (6) the related accretion. In short, all of Telos'
obligations with respect to the ERPS should have been accrued and presented on
Telos' balance sheet. Telos and its auditors chose not to reveal this
information to the SEC or to the public at large.

Among other possible legal consequences, this material misstatement constitutes
a violation of the Public Company Accounting Reform and Investor Protection Act
of 2002 ("Sarbanes-Oxley"). To address these concerns, and in accordance with
the provisions of Sarbanes-Oxley, CBIII demands that within 30 days the Audit
Committee take the following actions:

    (1)  Conduct a full investigation of the accounting irregularities described
         above in relation to undistributed dividends of the ERPS in the form of
         additional shares of the ERPS that accrued during the period of fiscal
         year 1992 through June 1995;
    (2)  Issue restated financial statements for Telos for 2004 and year-to-date
         statements for 2005;
    (3)  Recover any cash bonuses to John B. Wood, as well as any other
         incentive-based or equity-based compensation made to Mr. Wood from
         Telos in the previous 12 months, including but not limited to any stock
         options granted to Mr. Wood;
    (4)  Recover any profits realized by Mr. Wood from the sale of securities of
         Telos within the past 12 months;
    (5)  Recover any cash bonuses paid to Michele Nakazawa, as well as any other
         incentive-based or equity-based compensation made to Ms. Nakazawa from
         Telos in the past 12 months, including but not limited to any stock
         options granted to Ms. Nakazawa; and
    (6)  Recover any profits realized by Ms. Nakazawa from the sale of
         securities of Telos within the past 12 months.

II. Material misstatement of ERPS balance sheet classification

Beginning with its 2004 Form 10-K and continuing through its June 30, 2005 Form
10-Q ("June 30 10-Q") Telos disclosed that it would not be able to meet the
mandatory redemption schedule set forth in the terms of the ERPS. These same
disclosures invoke Statement of Financial Accounting Standards No. 6 ("SFAS 6")
in an attempt to exchange Telos' short-term obligation to redeem and pay accrued
dividends on the ERPS into a long-term obligation. Telos' proposed justification
for this treatment remained unclear until its June 30 10-Q. Telos announced that
it could exchange the ERPS into specially-created junior debentures authorized
by the terms of the ERPS ("Exchange Debentures") which supposedly were not due
for payment until 2009.

Telos' epiphany that it could exchange the ERPS into Exchange Debentures to
avoid its short-term obligations was, at best, disingenuous. Telos knew that
there was no difference between the redemption schedules and dividend payment
dates of the ERPS and the Exchange Debentures. Prior to Telos' new statements
regarding the Exchange Debentures, Telos had already publicly represented in its
2004 10-K that:

         On any dividend payment date after November 21, 1991, [Telos] may
         exchange the [ERPS], in whole or in part, for [Exchange
         Debentures] that are redeemable upon terms substantially similar
         to the [ERPS] . . . . (December 31, 2004 10-K, Note 7: Redeemable
         Preferred Stock, emphasis added)

                                                                   Page 14 of 29

Telos made similar statements equating the repayment terms of the ERPS and the
Exchange Debentures in every single one of its 10-Ks for the past 15 years.

It was only after CBIII questioned Telos' SFAS 6 election and Exchange Debenture
strategy in a letter (and in a subsequently-filed Form SC 13D/A) to Goodman that
Telos seriously considered whether its treatment of the ERPS was appropriate.

Interestingly, Telos reversed its misstatements with respect to reclassifying
the ERPS obligation. In its September 30, 2005 Form 10-Q (filed late on November
21, 2005 due to "pending matters under review with the Company's independent
accountants and attorneys") Telos acknowledged that it "correctly classified the
entirety of its obligation to redeem the [ERPS] as a long-term obligation, but
that the specific basis previously stated for such conclusion was not correct."
Specifically, Telos recanted its previous justification for the long-term
treatment of the obligation because the redemption of the Exchange Debentures,
exactly like the redemption schedule of the ERPS, would require an initial
redemption payment in December 2005, constituting a short-term liability.

In correcting its first mistake, Telos then made a second mistake by citing a
new, and equally erroneous justification for its long-term treatment of the ERPS
obligations. Telos referred to a Senior Credit Facility Agreement with Wells
Fargo Foothill, Inc. (the "Credit Facility") which supposedly prohibits any
redemption of payment of dividends on any Telos stock so long as the Credit
Facility is outstanding and unpaid. Telos argued the Credit Facility prohibits
redemption of the ERPS and payment of dividends for more than twelve months, and
thus its ERPS-related obligations are properly considered long-term.

Telos' reasoning does not make logical sense. Telos points to Accounting
Research Bulletin No. 43 ("ARB 43") and argues that its obligations on the ERPS
are not "due and payable," either because it cannot make the required December
2005 redemption of the ERPS or pay accrued dividends on those shares due to
restrictions in the Credit Facility, or because it does not have the requisite
"legally available funds" under Maryland law.

Whether or not the Credit Facility or Maryland law requires Telos to delay
payment on the ERPS is completely irrelevant to the accounting treatment of
those obligations. Telos is required by the terms of the ERPS themselves to
redeem those shares and pay accrued dividends as of December 2005. Telos' intent
and ability to pay is irrelevant for the purposes of analyzing whether or not
there is an obligation to pay, and when that obligation comes due.(1) Telos'
absurd justification in its 10-Q, if taken to its logical extreme, would suggest
that Telos need not even classify the ERPS as a liability on its balance sheet
unless and until the Credit Facility expires and Telos has legally available
funds to redeem the ERPS and pay accrued dividends. The fact that Telos does not
go this far illustrates the dangerous inconsistency in its treatment of the
ERPS: namely Telos' concession that its ERPS-related obligations are, in fact,
liabilities under SFAS 150.

--------------------
(1)  Telos made similar arguments before with respect to the ERPS, and they were
     rejected as "nonsensical." In a 1998 lawsuit (Telos Corporation v. Cede &
     Co., U.S. District Court for the Eastern District of Virginia, Civ. No.
     97-439-A) Telos argued that the ERPS holders did not have the right to
     elect their Class D directors (as provided for in the terms of the
     securities), because Telos had not defaulted on its payments to the ERPS
     holders. Telos argued that even though it had failed to make any payments
     of dividends on the ERPS, it was not in default because Telos did not have
     legally available funds under Maryland law, and therefore the dividends on
     the ERPS were not due and owing in such a way as to trigger the election of
     the Class D directors. The court unequivocally disagreed with Telos and
     held that Telos' dividend arrearages on the ERPS were due and owing,
     regardless of Telos ability to pay those dividends as a result of its lack
     of available funds under Maryland law.

                                                                   Page 15 of 19

Second, Telos' arguments under Financial Accounting Standards Board Statement
No. 78 ("FASB 78") are grossly misplaced. SFAS 78 applies only to "callable
obligations," which are obligations that are "long-term obligations that are or
will be callable by the creditor either because the debtor's violation of a
provision of the debt agreement at the balance sheet date makes the obligation
callable or because the violation, if not cured within a specified grace period,
will make the obligation callable." As discussed above, the ERPS are not
long-term obligations but rather short-term obligations, and the redemption and
accrued dividend payment obligations arise on behalf of the ERPS holders without
any need for them to "call."

CBIII is deeply disturbed by Telos new justifications to improperly reclassify
the ERPS on Telos' balance sheet, neither of which provides a rationale
consistent with GAAP and GAAS. GAAP require that a company's financial
disclosures must fully and fairly present the results and financial position of
the issuer. Telos and Goodman's attempt to divert attention from what is
clearly, by the terms ERPS, a mandatory short-term obligation to redeem and pay
accrued dividends on the ERPS, amounts to a wrongful attempt to defeat the
overriding fairness principle of GAAP.

Telos recently received the final report from a so-called "independent committee
on capital restructuring" whose purpose was to investigate possible resolutions
of Telos' failure to redeem the ERPS and to pay the accrued dividends on those
shares. On November 3, 2005 Telos' Board of Directors accepted the
recommendation of the independent committee to pursue a restructure or
repurchase of the ERPS at a "significant discount." Our client believes it is
significant that the two material misstatements in Telos' financial statements
identified above both relate to the value of the ERPS, and would serve to reduce
the value of the ERPS in any negotiation of such a "significant discount."

Such a course of action directly benefits the common stockholders of Telos at
the expense of the more senior ERPS holders. Telos' Board of Directors approved
this strategy despite the fact that many of the Telos' directors are common
stockholders, therefore exacerbating the intractable conflict of interest
between Telos' Board of Directors and the ERPS holders as first acknowledged in
a February 18, 1994 13E--3 filed with the SEC stating that a "holder [such as
any officer or director of Telos] of any class of Common Stock could be deemed
to have interests which conflict with those of the holders of [ERPS]." CBIII
also believes it is significant that the two executive officers who certified
the materially misstated Telos financial statements have an admitted conflict of
interest with the ERPS holders, yet nevertheless certified financial statements
that materially misstated the ERPS position to the financial benefit of those
same executive officers.

The continuing problems with Telos' public financial statements demand your
immediate attention.

In addition to the demands already made by CBIII on Telos' Board of Directors,
our client demands that within 30 days from the date of this letter, you take
the following actions:

    (7)  Conduct a full investigation into the matters presented above,
         specifically the ERPS dividend accrual and the ERPS balance sheet
         classification;
    (8)  Conduct a full investigation into the actions of John B. Wood and
         Michele Nakazawa;
    (9)  Conduct a full investigation into whether Mr. Wood and Ms. Nakazawa
         have demonstrated the necessary competence and integrity to continue in
         their positions as CEO and CFO respectively, particularly in light of
         their involvement in the preparation, filing and certification of
         financial statements which materially misrepresent the financial
         condition of Telos;

                                                                   Page 16 of 29

    (10) Bring these and any other questionable accounting practices to the
         attention of the Special Litigation Committee; and
    (11) Issue restated financial statements for Telos for 2004 and year-to-date
         statements for 2005.

You, the other members of the Audit Committee of Telos, and Goodman are hereby
on notice that Telos' public financial disclosures filed with the SEC contain
serious material misstatements. You are also hereby on notice that Telos' CEO
and CFO have knowingly certified public financial disclosures containing
material misstatements that favor their own interests and the interests of the
Board of Directors of Telos over those of the more senior ERPS holders.
Accordingly, you should request the immediate resignation of John P. Wood and
Michele Nakazawa. CBIII will vigorously pursue additional claims against you in
the event that (1) Telos fails to issue corrected, restated financial
disclosures as requested above, and (2) new material misstatements and/or
fraudulent statements are discovered in Telos' SEC filings.

While our client believes it has no obligation to make a formal demand on Telos
before bringing these additional claims, our client nevertheless hereby makes
its formal demand in the event that a court should determine such a demand to be
necessary.

A failure to respond to CBIII, to take appropriate measures as enumerated above
and to report such actions in detail to us no later than 30 days from receipt of
this letter will result in our client pursuing appropriate legal and equitable
relief.

       Form of Warner Stevens Board Demand Letter dated December 27, 2005

Name and Address of
Member of Board of Directors

Re:      Telos Corporation
         -----------------


Dear Mr. __________:

We represent Costa Brava Partnership III, L.P. ("CBIII"), with regard to their
ownership of certain instruments denominated "12% Cumulative Exchangeable
Redeemable Preferred Stock" ("ERPS") of Telos Corporation ("Telos"). Our client
filed a lawsuit against you entitled Costa Brava Partnership III, L.P. v. Telos
Corporation et al. in the Circuit Court for Baltimore City, Cause No.
24-C--05-009296.

On behalf of CBIII we previously delivered to you a letter demanding action on
several matters also referenced in an attached lawsuit. CBIII cited numerous
instances of apparent violations of your duty of good faith. Specifically, you
authorized bonus payments and other discretionary income payments to certain
executives while claiming insufficient funds to pay mandatory dividends on the
ERPS. You also authorized inflated interest payments to Telos' largest
shareholder, John Porter, while you claimed insufficient funds to pay mandatory
dividends on the ERPS. We received no response from you, and you have taken no
serious action in response to the demands enumerated in our client's letter. In
the four sections below, CBIII cites further reasons why your actions and
omissions continue to lack the good faith required by Maryland law.

I. Improper Board additions.

In October 2005 Telos improperly added Mr. Bruce J. Stewart as a member of
Telos' Board of Directors. According to Telos' by-laws (which you and the other
directors presumably have read), the Board of Directors is initially capped at 6
members, and additional directors may only be appointed by resolution adopted by
the affirmative vote of a majority of the whole Board of Directors. Upon
information and belief, there was no vote appointing Mr. Stewart as a member of
the Board, and there was no vote increasing the number of Telos' directors.
There is no mention whatsoever of a Board vote in the Form 8-K which disclosed
the appointment of Mr. Stewart. The inexplicable failure to adhere to Telos'
organizational principles constitutes another flagrant violation of your
fiduciary duties to the corporation.

The subsequent appointment of Mr. Thomas L. Owsley to the Board of
Directors--again without the requisite majority vote--further illustrates your
disregard for Telos' corporate procedures and notions of fair play.

                                                                   Page 18 of 29

Almost four months after our client first contacted you with demands for action,
you and the other members of the Board of Directors finally created a Special
Litigation Committee to "investigate, review, and analyze the allegations made"
in our client's lawsuit against you. You then appointed Mr. Stewart, a named
defendant in the lawsuit and an improperly appointed Board member as discussed
above, to this supposed independent fact-finding committee. Mr. Stewart's
obvious and fundamental conflict of interest in investigating his own actions
cannot be cured. Rather than a good-faith effort to investigate our client's
claims, this belated "action" is more likely a futile attempt to manufacture
arguments for any motions to dismiss you may file. The Special Litigation
Committee, hopelessly confounded by the management of named defendants, is as
inappropriate as it is overdue.

In addition to the demands already made by CBIII on Telos' Board of Directors,
our client demands that within 30 days from the date of this letter, you take
the following actions:

    (1)  Remove Mr. Stewart from the Special Litigation Committee;
    (2)  Clarify that Mr. Stewart and Mr. Owsley are not duly appointed members
         of Telos' Board of Directors;
    (3)  Prohibit Mr. Stewart's and Mr. Owsley's participation in any future
         meetings of Telos' Board of Directors and Telos' Special Litigation
         Committee; and
    (4)  Take any remedial action necessary to redress any prior action by Mr.
         Stewart and Mr. Owsley as members of Telos' Board of Directors or
         participation by Mr. Stewart or Mr. Owsley as members of Telos' Board
         of Directors.

II. Material misstatement of ERPS dividend accrual

As part of our client's investigation into Telos' recent and historical
financial disclosures, CBIII retained the services of an independent accounting
firm to review Telos' filings with the Securities Exchange Commission ("SEC").
Their investigation--still in its early stages--has so far revealed two
significant material misstatements in Telos' filings with the SEC, leading to
one inexorable conclusion:

Telos has made and continues to make material misstatements in its public
disclosures.

For the fiscal years of 1992 through 1994, and for the dividend payable June 1,
1995, Telos accrued more than 1.5 million undistributed, undeclared dividends on
the ERPS in the form of additional shares of ERPS. Telos' financial statements
filed with the SEC wrongfully do not account for these additional undistributed
shares of ERPS at their current mandatory redemption value at $10 per share.
Furthermore, Telos' financials wrongfully fail to account for the accrual of
mandatory dividends on these undistributed ERPS shares.

The reported value of the ERPS on Telos' current balance sheet thus materially
understates the mandatory financial obligation of the ERPS by more than $30
million.

To satisfy its obligations under both Generally Accepted Accounting Principles
("GAAP") and Generally Accepted Auditing Standards ("GAAS"), Telos should have
fully disclosed these undistributed shares. If properly accrued and presented in
Telos' financial statements, the liability should have included: (1) the issue
price of the ERPS shares; (2) the accretion necessary to amortize the difference
between the issue price and the redemption price over the period of time from
issuance to the stated maturity dates; (3) the issue price of the declared stock
dividends; (4) the related accretion; (5) the issue price of the stock dividends
that would have been declared had Telos done so in lieu of the cash dividends
that it did not pay; and (6) the related accretion. In short, all of Telos'

                                                                   Page 19 of 29

obligations with respect to the ERPS should have been accrued and presented on
Telos' balance sheet. Telos and its auditors chose not to reveal this
information to the SEC or to the public at large.

Among other likely legal consequences, this material misstatement constitutes a
violation of the Public Company Accounting Reform and Investor Protection Act of
2002 ("Sarbanes-Oxley"). To address these concerns, and in accordance with the
provisions of Sarbanes-Oxley, CBIII demands that within 30 days the Board of
Directors take the following actions:

    (5)  Conduct a full investigation of the accounting irregularities described
         above in relation to undistributed dividends of the ERPS in the form of
         additional shares of the ERPS that accrued during the period of fiscal
         year 1992 through June 1995;
    (6)  Issue restated financial statements for Telos for 2004 and year-to-date
         statements for 2005;
    (7)  Recover any cash bonuses to John B. Wood, as well as any other
         incentive-based or equity-based compensation made to Mr. Wood from
         Telos in the previous 12 months, including but not limited to any stock
         options granted to Mr. Wood;
    (8)  Recover any profits realized by Mr. Wood from the sale of securities of
         Telos within the past 12 months;
    (9)  Recover any cash bonuses paid to Michele Nakazawa, as well as any other
         incentive-based or equity-based compensation made to Ms. Nakazawa from
         Telos in the past 12 months, including but not limited to any stock
         options granted to Ms. Nakazawa; and
    (10) Recover any profits realized by Ms. Nakazawa from the sale of
         securities of Telos within the past 12 months.

III. Material misstatement of ERPS balance sheet classification

Beginning with its 2004 Form 10-K and continuing through its June 30, 2005 Form
10-Q ("June 30 10-Q") Telos disclosed that it would not be able to meet the
mandatory redemption schedule set forth in the terms of the ERPS. These same
disclosures invoke Statement of Financial Accounting Standards No. 6 ("SFAS 6")
in an attempt to exchange Telos' short-term obligation to redeem and pay accrued
dividends on the ERPS into a long-term obligation. Telos' proposed justification
for this treatment remained unclear until its June 30 10-Q. Telos announced that
it could exchange the ERPS into specially-created junior debentures authorized
by the terms of the ERPS ("Exchange Debentures") which supposedly were not due
for payment until 2009.

Telos' epiphany that it could exchange the ERPS into Exchange Debentures to
avoid its short-term obligations was, at best, disingenuous. Telos knew that
there was no difference between the redemption schedules and dividend payment
dates of the ERPS and the Exchange Debentures. Prior to Telos' new statements
regarding the Exchange Debentures, Telos had already publicly represented in its
2004 10-K that:

         On any dividend payment date after November 21, 1991, [Telos] may
         exchange the [ERPS], in whole or in part, for [Exchange
         Debentures] that are redeemable upon terms substantially similar
         to the [ERPS] . . . . (December 31, 2004 10-K, Note 7: Redeemable
         Preferred Stock, emphasis added)

Telos made similar statements equating the repayment terms of the ERPS and the
Exchange Debentures in every single one of its 10-Ks for the past 15 years.

                                                                   Page 20 of 29

It was only after CBIII questioned Telos' SFAS 6 election and Exchange Debenture
strategy in a letter (and in a subsequently-filed Form SC 13D/A) to Telos'
auditors Goodman & Company, LLP ("Goodman") that Telos seriously considered
whether its treatment of the ERPS was appropriate.

Interestingly, Telos reversed its misstatements with respect to reclassifying
the ERPS obligation. In its September 30, 2005 Form 10-Q (filed late on November
21, 2005 due to "pending matters under review with the Company's independent
accountants and attorneys") Telos acknowledged that it "correctly classified the
entirety of its obligation to redeem the [ERPS] as a long-term obligation, but
that the specific basis previously stated for such conclusion was not correct."
Specifically, Telos recanted its previous justification for the long-term
treatment of the obligation because the redemption of the Exchange Debentures,
exactly like the redemption schedule of the ERPS, would require an initial
redemption payment in December 2005, constituting a short-term liability.

In correcting its first mistake, Telos then made a second mistake by citing a
new, and equally erroneous justification for its long-term treatment of the ERPS
obligations. Telos referred to a Senior Credit Facility Agreement with Wells
Fargo Foothill, Inc. (the "Credit Facility") which supposedly prohibits any
redemption or payment of dividends on any Telos stock so long as the Credit
Facility is outstanding and unpaid. Telos argued the Credit Facility prohibits
redemption of the ERPS and payment of dividends for more than twelve months, and
thus its ERPS-related obligations are properly considered long-term.

Telos' reasoning does not make logical sense. Telos points to Accounting
Research Bulletin No. 43 ("ARB 43") and argues that its obligations on the ERPS
are not "due and payable," either because it cannot make the required December
2005 redemption of the ERPS or pay accrued dividends on those shares due to
restrictions in the Credit Facility, or because it does not have the requisite
"legally available funds" under Maryland law.

Whether or not the Credit Facility or Maryland law requires Telos to delay
payment on the ERPS is completely irrelevant to the accounting treatment of
those obligations. Telos is required by the terms of the ERPS themselves to
redeem those shares and pay accrued dividends as of December 2005. Telos' intent
and ability to pay is irrelevant for the purposes of analyzing whether or not
there is an obligation to pay, and when that obligation comes due.(1) Telos'
absurd justification in its latest 10-Q, if taken to its logical extreme, would
suggest that Telos need not even classify the ERPS as a liability on its balance
sheet unless and until the Credit Facility expires and Telos has legally
available funds to redeem the ERPS and pay accrued dividends. The fact that
Telos does not go this far illustrates the dangerous inconsistency in its
treatment of the ERPS: namely Telos' concession that its ERPS-related
obligations are, in fact, liabilities under SFAS 150.

--------------------
(1)  Telos made similar arguments before with respect to the ERPS, and they were
     rejected as "nonsensical." In a 1998 lawsuit (Telos Corporation v. Cede &
     Co., U.S. District Court for the Eastern District of Virginia, Civ. No.
     97-439-A) Telos argued that the ERPS holders did not have the right to
     elect their Class D directors (as provided for in the terms of the
     securities), because Telos had not defaulted on its payments to the ERPS
     holders. Telos argued that even though it had failed to make any payments
     of dividends on the ERPS, it was not in default because Telos did not have
     legally available funds under Maryland law, and therefore the dividends on
     the ERPS were not due and owing in such a way as to trigger the election of
     the Class D directors. The court unequivocally disagreed with Telos and
     held that Telos' dividend arrearages on the ERPS were due and owing,
     regardless of Telos ability to pay those dividends as a result of its lack
     of available funds under Maryland law.

                                                                   Page 21 of 29

Second, Telos' arguments under Financial Accounting Standards Board Statement
No. 78 ("FASB 78") are grossly misplaced. SFAS 78 applies only to "callable
obligations," which are obligations that are "long-term obligations that are or
will be callable by the creditor either because the debtor's violation of a
provision of the debt agreement at the balance sheet date makes the obligation
callable or because the violation, if not cured within a specified grace period,
will make the obligation callable." As discussed above, the ERPS are not
long-term obligations but rather short-term obligations, and the redemption and
accrued dividend payment obligations arise on behalf of the ERPS holders without
any need for them to "call."

CBIII is deeply disturbed by Telos new justifications to improperly reclassify
the ERPS on Telos' balance sheet, neither of which provides a rationale
consistent with GAAP and GAAS. GAAP require that a company's financial
disclosures must fully and fairly present the results and financial position of
the issuer. Telos and Goodman's attempt to divert attention from what is
clearly, by the terms ERPS, a mandatory short-term obligation to redeem and pay
accrued dividends on the ERPS, amounts to a wrongful attempt to defeat the
overriding fairness principle of GAAP.

In addition to the demands already made by CBIII on Telos' Board of Directors,
our client demands that within 30 days from the date of this letter, you take
the following actions:

    (11) Conduct a full investigation into the matters presented above,
         specifically the ERPS dividend accrual and the ERPS balance sheet
         classification;
    (12) Bring these and any other questionable accounting practices to the
         attention of the Special Litigation Committee;
    (13) Request the immediate resignation of John B. Wood and Michele Nakazawa;
    (14) Conduct a full investigation into the prior actions of Wood and
         Nakazawa;
    (15) Conduct a full investigation into whether Mr. Wood and Ms. Nakazawa
         have demonstrated the necessary competence and integrity to continue in
         their positions as CEO and CFO respectively, particularly in light of
         their involvement in the preparation, filing and certification of
         financial statements which materially misrepresent the financial
         condition of Telos; and
    (16) Issue restated financial statements for Telos for 2004 and year-to-date
         statements for 2005.

IV. Conflicts of Interest

Telos recently received the final report from a so-called "independent committee
on capital restructuring" whose purpose was to investigate possible resolutions
of Telos' failure to redeem the ERPS and to pay the accrued dividends on those
shares. On November 3, 2005 Telos' Board of Directors accepted the
recommendation of the independent committee to pursue a restructure or
repurchase of the ERPS at a "significant discount." Our client believes it is
significant that the two material misstatements in Telos' financial statements
identified above both relate to the value of the ERPS, and would serve to reduce
the value of the ERPS in any negotiation of such a "significant discount."

Such a course of action directly benefits the common stockholders of Telos at
the expense of the more senior ERPS holders. Telos' Board of Directors approved
this strategy despite the fact that many of Telos' directors are common
stockholders, therefore exacerbating the intractable conflict of interest
between Telos' Board of Directors and the ERPS holders as first acknowledged in
a February 18, 1994 13E--3 filed with the SEC stating that a "holder [such as
any officer or director of Telos] of any class of Common Stock could be deemed
to have interests which conflict with those of the holders of [ERPS]." CBIII
also believes it is significant that the two executive officers who certified
the materially misstated Telos financial statements have an admitted conflict of
interest with the ERPS holders, yet nevertheless certified financial statements
that materially misstated the ERPS position to the financial benefit of those
same executive officers.

                                                                   Page 22 of 29

These same conflicts of interest are evidenced in the wrongful appointment of
Mr. Stewart and Mr. Owsley to the Board of Directors in response to CBIII's
lawsuit. Mr. Stewart and Mr. Owsley were not appointed in accordance with Telos'
established procedures. On the back of these wrongful appointments, the Board
established a suspect Special Litigation Committee headed by a defendant to the
lawsuit that is supposedly being investigated. All the while Telos' officers and
directors who are common shareholders benefit from materially misstated
financial disclosures at the expense of the more senior ERPS holders.

Telos is required to indemnify its directors and officers only in instances
where the director or officer has acted in good faith. These continuing
conflicts of interest and lack of good faith exhibited by Telos' officers and
directors vitiates any obligation of Telos to indemnify its officers and
directors from harm with respect to CBIII's lawsuit against them.

In addition to the demands already made by CBIII on Telos' Board of Directors,
our client demands that within 30 days from the date of this letter, you take
the following actions:

    (17) Deny any request by any officer or director of Telos for
         indemnification from harm with respect to CBIII's lawsuit against them;
         and
    (18) Deny any request by any officer or director of Telos to submit this
         matter to Telos' insurance carrier for indemnification coverage.

While our client believes it has no obligation to make a formal demand on Telos
before bringing these additional claims, our client nevertheless hereby makes
its formal demand in the event that a court should determine such a demand to be
necessary.

A failure to respond to CBIII, to take appropriate measures as enumerated above
and to report such actions in detail to us no later than 30 days from receipt of
this letter will result in our client pursuing appropriate legal and equitable
relief.

Dear Mr. Wood, Ms. Nakazawa:

We represent Costa Brava Partnership III, L.P. ("CBIII"), with regard to their
ownership of certain instruments denominated "12% Cumulative Exchangeable
Redeemable Preferred Stock" ("ERPS") of Telos Corporation ("Telos"). Our client
filed a lawsuit against you entitled Costa Brava Partnership III, L.P. v. Telos
Corporation et al. in the Circuit Court for Baltimore City, Cause No.
24-C--05-009296.

On behalf of CBIII we previously delivered to you a letter demanding action on
several matters also referenced in an attached lawsuit. CBIII cited numerous
instances of apparent violations of your duty of good faith. Specifically, you
authorized bonus payments and other discretionary income payments to certain
executives while claiming insufficient funds to pay mandatory dividends on the
ERPS. You also authorized inflated interest payments to Telos' largest
shareholder, John Porter, while you claimed insufficient funds to pay mandatory
dividends on the ERPS. Our client received no response from you, and you have
taken no serious action in response to the demands enumerated in our letter. In
the three sections below, CBIII cites further reasons why your actions and
omissions continue to lack the good faith required by Maryland law.

I. Material misstatement of ERPS dividend accrual

As part of our client's investigation into Telos' recent and historical
financial disclosures, CBIII retained the services of an independent accounting
firm to review Telos' filings with the Securities Exchange Commission ("SEC").
Their investigation--still in its early stages--has so far revealed two
significant material misstatements in Telos' filings with the SEC, leading to
one inexorable conclusion:.

Telos has made and continues to make material misstatements in its public
disclosures, which by your signature are certified to be in compliance with the
Public Company Accounting Reform and Investor Protection Act of 2002
("Sarbanes-Oxley").

For the fiscal years of 1992 through 1994, and for the dividend payable June 1,
1995, Telos accrued more than 1.5 million undistributed, undeclared dividends on
the ERPS in the form of additional shares of the ERPS. Telos' financial
statements filed with the SEC wrongfully do not account for these additional
undistributed shares of ERPS at their current mandatory redemption value at $10
per share. Furthermore, Telos' financials wrongfully fail to account for the
accrual of mandatory dividends on these undistributed ERPS shares.

                                                                   Page 24 of 29

The reported value of the ERPS on Telos' current balance sheet, certified by
your signature, thus materially understates the mandatory financial obligation
of the ERPS by more than $30 million.

To satisfy its obligations under both Generally Accepted Accounting Principles
("GAAP") and Generally Accepted Auditing Standards ("GAAS"), Telos should have
fully disclosed these undistributed shares. If properly accrued and presented in
Telos' financial statements, the liability should have included: (1) the issue
price of the ERPS shares; (2) the accretion necessary to amortize the difference
between the issue price and the redemption price over the period of time from
issuance to the stated maturity dates; (3) the issue price of the declared stock
dividends; (4) the related accretion; (5) the issue price of the stock dividends
that would have been declared had Telos done so in lieu of the cash dividends
that it did not pay; and (6) the related accretion. In short, all of Telos'
obligations with respect to the ERPS should have been accrued and presented on
Telos' balance sheet. Telos and its auditors chose not to reveal this
information to the SEC or to the public at large.

II. Material misstatement of ERPS balance sheet classification

Beginning with its 2004 Form 10-K and continuing through its June 30, 2005 Form
10-Q ("June 30 10-Q") Telos disclosed that it would not be able to meet the
mandatory redemption schedule set forth in the terms of the ERPS. These same
disclosures invoke Statement of Financial Accounting Standards No. 6 ("SFAS 6")
in an attempt to exchange Telos' short-term obligation to redeem and pay accrued
dividends on the ERPS into a long-term obligation. Telos' proposed justification
for this treatment remained unclear until its June 30 10-Q. Telos announced that
it could exchange the ERPS into specially-created junior debentures authorized
by the terms of the ERPS ("Exchange Debentures") which supposedly were not due
for payment until 2009.

Telos' epiphany that it could exchange the ERPS into Exchange Debentures to
avoid its short-term obligations was, at best, disingenuous. Telos knew that
there was no difference between the redemption schedules and dividend payment
dates of the ERPS and the Exchange Debentures. Prior to Telos' new statements
regarding the Exchange Debentures, Telos had already publicly represented in its
2004 10-K that:

         On any dividend payment date after November 21, 1991, [Telos] may
         exchange the [ERPS], in whole or in part, for [Exchange
         Debentures] that are redeemable upon terms substantially similar
         to the [ERPS] . . . . (December 31, 2004 10-K, Note 7: Redeemable
         Preferred Stock, emphasis added)

Telos made similar statements equating the repayment terms of the ERPS and the
Exchange Debentures in every single one of its 10-Ks for the past 15 years.

It was only after CBIII questioned Telos' SFAS 6 election and Exchange Debenture
strategy in a letter (and in a subsequently-filed Form SC 13D/A) to Telos'
auditors Goodman & Company, LLP ("Goodman") that Telos seriously considered
whether its treatment of the ERPS was appropriate.

Interestingly, Telos reversed its misstatements with respect to reclassifying
the ERPS obligation. In its September 30, 2005 Form 10-Q (filed late on November
21, 2005 due to "pending matters under review with the Company's independent
accountants and attorneys") Telos acknowledged that it "correctly classified the
entirety of its obligation to redeem the [ERPS] as a long-term obligation, but
that the specific basis previously stated for such conclusion was not correct."
Specifically, Telos recanted its previous justification for the long-term
treatment of the obligation because the redemption of the Exchange Debentures,
exactly like the redemption schedule of the ERPS, would require an initial
redemption payment in December 2005, constituting a short-term liability.

                                                                   Page 25 of 29

In correcting its first mistake, Telos then made a second mistake by citing a
new, and equally erroneous justification for its long-term treatment of the ERPS
obligations.(1) Telos referred to a Senior Credit Facility Agreement with Wells
Fargo Foothill, Inc. (the "Credit Facility") which supposedly prohibits any
redemption or payment of dividends on any Telos stock so long as the Credit
Facility is outstanding and unpaid. Telos argued the Credit Facility prohibits
redemption of the ERPS and payment of dividends for more than twelve months, and
thus its ERPS-related obligations are properly considered long-term.

Telos' reasoning does not make logical sense. Telos points to Accounting
Research Bulletin No. 43 ("ARB 43") and argues that its obligations on the ERPS
are not "due and payable," either because it cannot make the required December
2005 redemption of the ERPS or pay accrued dividends on those shares due to
restrictions in the Credit Facility, or because it does not have the requisite
"legally available funds" under Maryland law.

Whether or not the Credit Facility or Maryland law requires Telos to delay
payment on the ERPS is completely irrelevant to the accounting treatment of
those obligations. Telos is required by the terms of the ERPS themselves to
redeem those shares and pay accrued dividends as of December 2005. Telos' intent
and ability to pay is irrelevant for the purposes of analyzing whether or not
there is an obligation to pay, and when that obligation comes due.(2) Telos'
absurd justification in its 10-Q, if taken to its logical extreme, would suggest
that Telos need not even classify the ERPS as a liability on its balance sheet
unless and until the Credit Facility expires and Telos has legally available
funds to redeem the ERPS and pay accrued dividends. The fact that Telos does not
go this far illustrates the dangerous inconsistency in its treatment of the
ERPS: namely Telos' concession that its ERPS-related obligations are, in fact,
liabilities under SFAS 150.

Second, Telos' arguments under Financial Accounting Standards Board Statement
No. 78 ("FASB 78") are grossly misplaced. SFAS 78 applies only to "callable
obligations," which are obligations that are "long-term obligations that are or
will be callable by the creditor either because the debtor's violation of a
provision of the debt agreement at the balance sheet date makes the obligation
callable or because the violation, if not cured within a specified grace period,
will make the obligation callable." As discussed above, the ERPS are not
long-term obligations but rather short-term obligations, and the redemption and
accrued dividend payment obligations arise on behalf of the ERPS holders without
any need for them to "call."

--------------------
(1)  Our client notes with interest that Ms. Nakazawa, in her capacity as CFO,
     did not certify Telos' September 2005 10-Q, while Mr. Wood did. CBIII looks
     forward to questioning Ms. Nakazawa regarding the reasons for this
     omission when the lawsuit proceeds to the discovery phase.

(2)  Telos made similar arguments before with respect to the ERPS, and they were
     rejected as "nonsensical." In a 1998 lawsuit (Telos Corporation v. Cede &
     Co., U.S. District Court for the Eastern District of Virginia, Civ. No.
     97-439-A) Telos argued that the ERPS holders did not have the right to
     elect their Class D directors (as provided for in the terms of the
     securities), because Telos had not defaulted on its payments to the ERPS
     holders. Telos argued that even though it had failed to make any payments
     of dividends on the ERPS, it was not in default because Telos did not have
     legally available funds under Maryland law, and therefore the dividends on
     the ERPS were not due and owing in such a way as to trigger the election of
     the Class D directors. The court unequivocally disagreed with Telos and
     held that Telos' dividend arrearages on the ERPS were due and owing,
     regardless of Telos ability to pay those dividends as a result of its lack
     of available funds under Maryland law.

                                                                   Page 26 of 29

CBIII is deeply disturbed by Mr. Wood's certification of Telos' new
justifications to improperly reclassify the ERPS on Telos' balance sheet,
neither of which provides a rationale consistent with GAAP and GAAS. GAAP
require that a company's financial disclosures must fully and fairly present the
results and financial position of the issuer. Telos and Goodman's attempt to
divert attention from what is clearly, by the terms ERPS, a mandatory short-term
obligation to redeem and pay accrued dividends on the ERPS, amounts to a
wrongful attempt to defeat the overriding fairness principle of GAAP.

III. Conflicts of Interest

Telos recently received the final report from a so-called "independent committee
on capital restructuring" whose purpose was to investigate possible resolutions
of Telos' failure to redeem the ERPS and to pay the accrued dividends on those
shares. On November 3, 2005 Telos' Board of Directors accepted the
recommendation of the independent committee to pursue a restructure or
repurchase of the ERPS at a "significant discount." Our client believes it is
significant that the two material misstatements in Telos' financial statements
identified above both relate to the value of the ERPS, and would serve to reduce
the value of the ERPS in any negotiation of such a "significant discount."

Such a course of action directly benefits you and the other common stockholders
of Telos at the expense of the more senior ERPS holders. Telos' Board of
Directors approved this strategy despite the fact that you and many others of
Telos' directors are common stockholders, therefore exacerbating the intractable
conflict of interest between Telos' Board of Directors and the ERPS holders as
first acknowledged in a February 18, 1994 13E--3 filed with the SEC stating that
a "holder [such as any officer or director of Telos] of any class of Common
Stock could be deemed to have interests which conflict with those of the holders
of [ERPS]." CBIII also believes it is significant that the two executive
officers who certified the materially misstated Telos financial statements have
an admitted conflict of interest with the ERPS holders, yet nevertheless
certified financial statements that materially misstated the ERPS position to
the financial benefit of those same executive officers.

These same conflicts of interest are evidenced in the wrongful appointment of
Mr. Stewart and Mr. Owsley to the Board of Directors in response to our client's
lawsuit. Mr. Stewart and Mr. Owsley were not appointed in accordance with Telos'
established procedures. On the back of these wrongful appointments, the Board
established a suspect Special Litigation Committee headed by a defendant to the
lawsuit that is supposedly being investigated. All the while Telos' officers and
directors who are common shareholders benefit from materially misstated
financial disclosures at the expense of the more senior ERPS holders.

You are in serious breach of your fiduciary duties to Telos. Among other
possible legal consequences, your actions constitute a violation of Maryland
Code, Corps. & Assn's ss. 2-405.1 and Sarbanes-Oxley. To address our client's
concerns, and in accordance with the provisions of Sarbanes-Oxley, CBIII demands
that within 30 days you take the following actions:

                                                                   Page 27 of 29

    (1)  Immediately resign your position with Telos and its subsidiaries;
    (2)  Disgorge any cash bonuses, as well as any other incentive-based or
         equity-based compensation paid to you from Telos or its subsidiaries in
         the previous 12 months, including but not limited to any stock options
         granted to you; and 
    (3)  Disgorge any profits realized from the sale of securities of Telos
         within the past 12 months.

While our client believes it has no obligation to make a formal demand on Telos
before bringing these additional claims, our client nevertheless hereby makes
its formal demand in the event that a court should determine such a demand to be
necessary.

A failure to respond to CBIII, to take appropriate measures as enumerated above
and to report such actions in detail to us no later than 30 days from receipt of
this letter will result in our client pursuing appropriate legal and equitable
relief.


Very truly yours,

VIA DHL OVERNIGHT DELIVERY
--------------------------

Mr. Thomas L. Owsley 
c/o DLA Piper Rudnick Gray Carey US LLP 
6225 Smith Avenue
Baltimore, Maryland 21209

Dear Mr. Owsley,

We represent Costa Brava Partnership III, L.P. ("CBIII"), the owners of certain
instruments denominated "12% Cumulative Exchangeable Redeemable Preferred Stock"
("ERPS") of Telos Corporation ("Telos") and the Plaintiff in Cause No.
24-C-05-009296, styled Costa Brava Partnership III, L.P. v. Telos Corporation,
et al. (the "Lawsuit"). We write as a result of the form 8-K filing of Telos
filed on or about December 22, 2005.

As an initial item of concern, it appears that your appointment to the Telos
Board of Directors (the "Board") lacks compliance with Telos' by-laws. According
to Telos' by-laws, the Board is initially capped at 6 members, and the Board may
only be expanded and new directors appointed by resolution adopted by the
affirmative vote of a majority of the whole Board. Upon information and belief,
there was no such vote either expanding the Board or approving your appointment.
These concerns apply equally to Mr. Bruce Stewart, whose appointment to the
Board also appears to be in violation of Telos' by-laws. Given these concerns,
it is unclear how you and Mr. Stewart may properly sit on the Special Litigation
Committee (the "Committee") appointed by the Board.

Moreover, our client is particularly concerned with the inclusion of Mr. Bruce
Stewart in the Committee. As we are sure you are aware, Mr. Stewart is a named
defendant in the Lawsuit. Accordingly, our client questions the Committee's
ability to truly conduct a good faith investigation of the claims asserted in
the Lawsuit, as well as the role(s) of the named Defendants with respect to
these claims.

Finally, the concerns underlying the claims in the Lawsuit were raised with the
Board prior to the filing of the Lawsuit. Despite having an adequate opportunity
to do so, the Board chose not to respond to our client. While our client
welcomes a good faith investigation of the concerns outlined in the Lawsuit,
given the belated (and questionable) appointment of the Committee (and its
membership), our client does question Telos and the Board's true motivation.
Accordingly, we will vigorously oppose any efforts by the Board or Telos to
delay the Lawsuit as a result of the appointment of the Committee.

Despite the foregoing concerns, and without waiving same, our client presumes
that the Committee does intend to conduct a good faith investigation of the
concerns raised in the Lawsuit. To that end, we have enclosed additional
correspondence which we have delivered to the Board, the Audit Committee and Mr.

                                                                   Page 29 of 29

Wood and Ms. Nakazawa outlining additional items of concern. We anticipate that
your investigation will include speaking with our client and this firm regarding
these concerns and we certainly will welcome such efforts. However, our client
will also be closely monitoring the Committee's investigation and will
vigorously pursue litigation if this investigation is not conducted in good
faith.



Very truly yours,
