Item 5.  Other Events

                  On December 30, 1997, American  Communications  Services, Inc.
(the "Company")  entered into a Loan and Security Agreement with AT&T Commercial
Finance  Corporation  (the "New AT&T  Credit  Facility")  pursuant to which AT&T
Commercial  Finance  Corporation  has  agreed to  provide  up to $35  million in
financing for (i) the purpose of refinancing (the "Refinancing") all loans owing
by each  of  American  Communication  Services  of  Louisville,  Inc.,  American
Communication  Services of Fort Worth, Inc., American  Communication Services of
Columbia, Inc., American Communication Services of Greenville, Inc. and American
Communication   Services  of  El  Paso,  Inc.  (the  foregoing,   the  "Indebted
Subsidiaries")  to AT&T Credit  Corporation  made under a $31.2 million credit
facility and (ii) general corporate purposes.

                  The loans  under the New AT&T Credit  Facility  are secured by
the capital stock of the material subsidiaries of the Company and the promissory
notes (the "Intercompany  Notes") of the Indebted  Subsidiaries  evidencing debt
provided by the Company pursuant to the Refinancing.  The aggregate  outstanding
principal  balance  of the loans is  payable  in  twenty-four  (24)  consecutive
quarterly  installments beginning on December 31, 1998 and continuing on each of
the last calendar days (or the next succeeding  business day if such date is not
a business  day) of March,  June,  September  and December in each calendar year
thereafter  through and including  September 30, 2004. The principal of borrowed
amounts may be prepaid in certain  circumstances  and must be  prepaid,  without
premium or penalty, in other circumstances.  Interest is due quarterly. Interest
is variable based on the  three-month  Commercial  Paper Rate or LIBOR Rate plus
4.5% per annum,  at the  Company's  option,  and is compounded  quarterly.  Upon
certain  events of  default,  additional  interest  at a rate of 2% will  become
payable. In addition,  the New AT&T Credit Facility includes covenants,  some of
which impose certain  restrictions on the Company and its material  subsidiaries
including  restrictions on the declaration or payment of dividends,  the conduct
of certain activities,  certain investments, the creation of additional liens or
indebtedness,  the  disposition  of assets,  transactions  with  affiliates  and
extraordinary corporate transactions.

                  In connection with the New AT&T Credit  Facility,  the Company
issued to AT&T Credit Corporation 207,964 shares of its common stock in exchange
for AT&T Credit  Corporation  conveying  to the Company (i) 145 shares of common
stock of American Communication Services of Columbia,  Inc., (ii) 14.5 shares of
common  stock of American  Communication  Services of El Paso,  Inc.,  (iii) 145
shares of common stock of American  Communication  Services of Fort Worth, Inc.,
(iv)  145  shares  of  common  stock  of  American   Communication  Services  of
Greenville, Inc., and (v) 156.3 shares of common stock of American Communication
Services  of  Louisville,  Inc.  The  Company  was  required  to  pledge to AT&T
Commercial  Finance  Corporation  (i) all of its shares  (present and future) of
capital stock in its material subsidiaries,  along with all options and warrants
therein,  (ii) the  Intercompany  Notes  and (iii)  any  proceeds  of any of the
foregoing.  Under certain  circumstances,  the pledge  agreement  governing such
pledge also restricts the Company's  ability to receive and retain  dividends in
respect of the pledged collateral.

                  A  copy  of the  Loan  and  Security  Agreement,  dated  as of
December 30, 1997, between the Company and AT&T Commercial Finance  Corporation,
relating to the above-described transaction is attached as Exhibit 99 hereto.

                  SECTION  2.01.  Agreement  to Lend.  Subject  to the terms and
conditions  herein and relying upon the  representations  and  warranties of the
Borrower  herein (unless the Commitment of Lender shall have been  terminated in
accordance  with the terms  hereof),  Lender agrees to make Loans to Borrower in
the amount of the Commitment Amount on the Funding Date.

                  SECTION 2.02.  Purpose of Loan. The Loans made to the Borrower
shall be used by the  Borrower  (i) to make Loans to  Indebted  Subsidiaries  to
enable the Indebted  Subsidiaries to repay all outstanding  obligations owing by
them to AT&T Credit Corporation, and (ii) for general corporate purposes.

                  SECTION  2.03.  The Note.  All the Loans shall be evidenced by
the Note. The Loans shall bear interest from the Funding Date on the outstanding
principal  balance  thereof as set forth in Section 2.04.  Lender shall,  and is
authorized  and  directed by the  Borrower to register on Schedule A to the Note
the date, amount, and maturity of the Loans, and to register the date and amount
of each payment on the Loans,  and such Schedule A shall be conclusive  evidence
of the  amounts  owing to Lender  with  respect  to the Loans in the  absence of
manifest error;  provided,  however,  that the failure of Lender to register any
such  information on such schedule shall not in any manner affect the obligation
of the Borrower to repay the Loans in accordance with the terms of the Note.

                  SECTION 2.04. Interest on Loans. (a) Subject to the provisions
of Section  2.06,  each Loan shall bear interest from and after the Funding Date
at a rate per annum for each Interest Period equal to the Commercial  Paper Rate
or the LIBOR Rate, as selected by the Borrower in a written notice  delivered to
the Lender at least two Business Days prior to the  commencement of the Interest
Period in question.  If the Borrower fails to deliver such written notice within
the prescribed time period, then the Loans shall bear interest at the Commercial
Paper Rate during the Interest Period in question. Interest shall be computed on
the  basis of a 360 day year  comprised  of  twelve  30 day  months,  compounded
quarterly.

                  (b) The Lender shall give prompt notice to the Borrower of the
applicable  LIBOR Rate  determined  by the Lender for each  Interest  Period for
which the Borrower has  requested  the Loans to bear interest at the LIBOR Rate,
including the applicable rate, if any,  appearing in Eastern Edition of The Wall
Street Journal or furnished by each Reference Bank or New York City bank, as the
case may be.

                  (c) If, with  respect to any  Interest  Period,  the Lender is
unable to  determine  the LIBOR Rate on the basis of the Eastern  Edition of The
Wall Street Journal or quotations of the Reference  Banks or New York City banks
to be selected by the Lender:

                  (i)      the Lender shall  forthwith  notify the Borrower that
                           the LIBOR Rate cannot be determined for such Interest
                           Period; and

                  (ii)     the  interest  rate on the  Loans  for such  Interest
                           Period will be the Commercial Paper Rate.

                  SECTION 2.05.  Payments.  (a)  Interest on the Loans shall be
 payable quarterly in arrears on each Payment Date.

                  (b) The aggregate  outstanding  principal balance of the Loans
shall be payable in twenty-four  consecutive quarterly installments beginning on
December 31, 1998 and  continuing  on each Payment Date  thereafter  through and
including  September 30, 2004. The amount of each principal  payment shall be as
follows:


         Payment Number                               Amount

                  1 to 4                              $437,500
                  5 to 8                              $875,000

                  13 to 16                            $1,750,000
                  17 to 24                            $2,187,500


                  SECTION 2.06. Default Rate of Interest. If all or a portion of
(a) the principal amount of the Loans, (b) any interest payable thereon,  or (c)
any other Obligations shall not be paid when due, such overdue amount shall bear
interest at a rate that is two percent (2%) per annum above the rate of interest
otherwise payable on the Loans from the date of non-payment until such amount is
paid in full.

                  SECTION  2.07.   Optional   Prepayment  of  Loans;   Mandatory
Prepayment  of Loans.  (a) Provided that no Event of Default has occurred and is
continuing and clause (b) below is not  applicable,  the Borrower shall have the
right upon the  provision of thirty days prior written  notice to Lender,  which
notice shall be irrevocable, on any Payment Date occurring on or after March 30,
1998, to prepay at least $5,000,000 of the outstanding  principal balance of the
Loans,  together  with accrued  interest  thereon and the  aggregate  Prepayment
Premiums, if any, with respect to the Loans being prepaid; provided, however, no
partial  prepayments  which would result in reducing the  aggregate  outstanding
principal  balance of the Loans to less than  $10,000,000,  shall be  permitted.
Partial prepayments shall be applied to the principal  installments of the Loans
in the inverse order of maturity.

                  (b)  Provided  that no Event of Default  has  occurred  and is
continuing  and either all of the Prepayment  Conditions  have been satisfied or
all of the Prepayment  Conditions  other than the condition  specified in clause
(v) of the definition  thereof have been satisfied,  the Borrower shall have the
right upon the  provision of thirty days prior written  notice to Lender,  which
notice  shall be  irrevocable,  on any  Payment  Date to prepay the  outstanding
principal  balance of all,  but not less than all, of the Loans,  together  with
accrued  interest  thereon,  without premium or penalty if all of the Prepayment
Conditions have been  satisfied,  and otherwise,  with the aggregate  Prepayment
Premiums, if any.

                  (c) Upon the  occurrence  of a Change of Control,  at the sole
option of Lender,  the Borrower shall prepay,  without  premium or penalty,  the
outstanding principal balance of all the Loans, and all other Obligations within
thirty  days after  receipt  of notice  from  Lender  requesting  such  payment,
together with accrued interest.

                  SECTION  2.08.  Payment,  etc.  All  payments by the  Borrower
hereunder  and under the Note shall be made to Lender by wire  transfer or other
electronic payment method to such bank accounts as Lender may designate, for the
account of Lender in U.S.  dollars in immediately  available funds by 2:00 p.m.,
New Jersey  time,  on the date on which such payment  shall be due.  Interest in
respect of the Loans  hereunder  shall  accrue from the  Funding  Date up to and
including the day prior to the date on which the Loans are paid in full.

                  SECTION 2.09.  Maximum Lawful  Interest Rate.  Notwithstanding
any provision  contained herein, the total liability of the Borrower for payment
of interest  pursuant hereto and the Note,  including any other charges or other
amounts, to the extent such charges and other amounts are deemed to be interest,
shall not exceed the maximum amount of such interest permitted by applicable law
to be charged,  collected, or received from the Borrower. If any payments by the
Borrower include interest in excess of such a maximum amount, Lender shall apply
such excess to the reduction of the unpaid principal amount due pursuant hereto,
without premium or penalty,  or if none is due, such excess shall be refunded to
the Borrower, as applicable.


                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

on a basis  consistent  with that of  preceding  periods  and are  complete  and
correct  in all  material  respects.  As of the date of the  Financials  (a) the
Financials  fairly  represent,  in accordance  with GAAP, the Borrower's and its
Subsidiaries' financial position and results of operations; and (b) there are no
omissions from the Financials or any other facts or circumstances  not reflected
in the Financials which are or may be material according to GAAP.

                  SECTION 3.04. No Material Adverse Change.  Except as disclosed

before any governmental  instrumentality  or other agency now pending or, to the
knowledge of the Borrower,  threatened  against or affecting the Borrower or any
property or rights of the Borrower as to which there is a reasonable possibility
of  an  adverse  determination  and  which,  if  adversely   determined,   would
individually or in the aggregate  materially impair the right of the Borrower to
carry  on  business  substantially  as  now  being  conducted  or  as  presently
contemplated or would result in any Material Adverse Effect.

                  SECTION 3.06. Tax Returns. The Borrower has filed or caused to
be filed all Federal, state and local tax returns which, to the knowledge of the
Borrower,  are  required to be filed and has paid or caused to be paid all taxes
as shown on such returns or on any assessment  received by it to the extent that
such taxes have become  due,  except  such taxes the  amount,  applicability  or
validity of which are being  contested in good faith by appropriate  proceedings
and with  respect  to which  the  Borrower  shall  have set  aside on its  books
adequate reserves with respect to such taxes as are required by GAAP.

                  SECTION 3.07. No Defaults.  The Borrower is not in default (i)
with respect to any judgment,  writ,  injunction,  decree, rule or regulation of
any  governmental  instrumentality  or other  agency  which could be  reasonably

observance or  fulfillment  of any of the  obligations,  covenants or conditions

Liens of any nature whatsoever, except Permitted Liens.

                  SECTION  3.09.  Licenses,  etc.  The Borrower has obtained all
Authorizations  and  approvals   required  by  any  Governmental   Authority  in
connection  with the  operation  of the  Borrower's  business  except  where the
failure to be so  licensed  or  approved  could not be  expected  to result in a
Material Adverse Effect.

                  SECTION  3.10.  Compliance  With Laws.  Except as disclosed on
Schedule 3.10, the  operations of the Borrower  comply in all material  respects
with all  applicable  federal,  state or local laws and  regulations,  including
environmental,   health  and  safety  statutes  and  regulations.  None  of  the
operations  of the  Borrower  is  subject  to  any  judicial  or  administrative
proceeding alleging the violation of any federal,  state or local environmental,
health or safety statute or regulation.  To the knowledge of the Borrower,  none
of  the  operations  of  the  Borrower  is  the  subject  of  federal  or  state
investigation  evaluating  whether any Remedial Action is needed to respond to a
Release of any  Contaminant  into the indoor or outdoor  environment.  Except as
disclosed  on Schedule  3.10,  the  Borrower  has not filed any notice under any
federal or state law indicating past or present  treatment,  storage or disposal
of a hazardous waste or reporting a Release of any  Contaminant  into the indoor
or outdoor  environment.  The Borrower has no contingent  liability of which the
Borrower has knowledge or reasonably  should have  knowledge in connection  with
any Release of any Contaminant into the indoor or outdoor environment.

                  SECTION  3.11.  ERISA.  Neither  the  Borrower  nor any  ERISA
Affiliate  maintains or  contributes to any Benefit Plan or  Multiemployer  Plan
other than a Benefit Plan or Multiemployer  Plan listed on Schedule 3.11 hereto.
Each Plan which is intended to be qualified  under Section 401(a) of the IRC has
been  determined  by the IRS to be so  qualified,  and each trust related to any
such Plan has been determined to be exempt from federal income tax under Section
501(a) of the IRC.  Except as disclosed on Schedule  3.11,  neither the Borrower
nor any ERISA Affiliate maintains or contributes to any employee welfare benefit
plan within the  meaning of Section  3(1) of ERISA  which  provides  benefits to
employees after  termination of employment other than as required by Section 601
of ERISA.  Neither the  Borrower  nor any ERISA  Affiliate  has  breached in any
material respect any of the  responsibilities,  obligations or duties imposed on
it by ERISA or the regulations  promulgated thereunder with respect to any Plan.
No Benefit Plan has incurred any accumulated  funding  deficiency (as defined in
Sections  302(a)(2)  of ERISA and  412(a) of the IRC),  whether  or not  waived.
Neither the Borrower nor any ERISA  Affiliate  nor any fiduciary of any Plan has
engaged in a material nonexempt  "prohibited  transaction"  described in Section
406 of ERISA or  Section  4975 of the IRC or has  taken  or  failed  to take any
action  which  would  constitute  or result in a  Termination  Event.  Except as
disclosed on Schedule  3.11,  neither the Borrower nor any ERISA  Affiliate  has
incurred any  liability  under Title IV of ERISA.  Schedule B to the most recent
annual  report  filed  with the IRS with  respect to each Plan is  complete  and
accurate  in all  material  respects.  Since the date of the  filing of the most
recent  annual  report  containing a Schedule B with the IRS,  there has been no
material adverse change in the funding status or financial condition of the Plan
relating to such  Schedule B. Neither the Borrower nor any ERISA  Affiliate  has
failed to make a material  required  contribution  or payment to a Multiemployer
Plan. Neither the Borrower nor any ERISA Affiliate has failed to make a required
installment  or any other  required  payment  under Section 412 of the IRC on or
before the due date for such  installment  or other payment under  circumstances
that have  resulted or are  reasonably  likely to result in the  imposition of a
Lien on the  assets  of the  Borrower  or any of its  Subsidiaries  pursuant  to
Section  412(n) of the IRC.  Neither the  Borrower  nor any ERISA  Affiliate  is
required to provide  security to a Plan under Section  401(a)(29) of the IRC due
to a Benefit Plan amendment that results in an increase in current liability for
the plan year.

                  SECTION 3.12.  Investment  Company Act; Public Utility Holding
Company Act. The Borrower is not an "investment company" as that term is defined
in, and is not otherwise subject to regulation under, the Investment Company Act
of 1940. The Borrower is not a "holding company" as that term is defined in, and
is not otherwise subject to regulation under, the Public Utility Holding Company
Act of 1935.

                  SECTION 3.13. Federal Reserve Regulations. The Borrower is not
engaged principally,  or as one of its important activities,  in the business of
extending  credit for the purpose of  purchasing  or carrying  any margin  stock
(within the meaning of  Regulation  G of the Board of  Governors  of the Federal
Reserve System of the United  States),  and no part of the proceeds of the Loans
hereunder  will be used to purchase or carry any such margin  stock or to extend
credit to others for the purpose of purchasing or carrying any such margin stock
or for any purpose that  violates,  or is  inconsistent  with, the provisions of
Regulation G, T, U or X of said Board of Governors.

                  SECTION 3.14.  Collateral.  The security  interest  granted by
Article VII hereof and possession by the Lender of the Collateral  consisting of
Intercompany  Notes,  create a valid and perfected first priority Lien in and to
such Collateral, enforceable against other Persons in all jurisdictions securing
the payment of the Obligations of the Borrower, subject only to Permitted Liens,
except as the  enforcement  thereof may be affected  by  applicable  bankruptcy,
reorganization,   insolvency,   moratorium  or  other  similar  laws   affecting
creditors' rights generally. .

                  SECTION  3.15.  Chief Place of Business.  As of the  execution
hereof,  the  principal  place of  business  and chief  executive  office of the
Borrower  is located at 131  National  Business  Parkway,  Suite 100,  Annapolis
Junction,  Maryland 20701. If any change in such location  occurs,  the Borrower
shall  notify  Lender  thereof  not later  than ten days  after  the  occurrence
thereof.  As of the date of execution hereof, the corporate books and records of
the Borrower are located at its chief executive office and all chattel paper and
all records of account of the  Borrower  are located at the  principal  place of
business of the  Borrower,  and if any change in any such location  occurs,  the
Borrower  shall  notify  Lender  thereof  not  later  than  ten days  after  the
occurrence thereof.

                  SECTION 3.16.  Other Corporate  Names.  Except as disclosed on
Schedule  3.16,  the  Borrower has not used,  and will not use any  corporate or
fictitious   name  other  than  the  corporate  name  shown  in  the  Borrower's
Certificate of Incorporation.

                  SECTION 3.17.  Insurance.  Schedule 3.17 contains a 
description of all insurance which the Borrower and its Subsidiaries maintains
with respect to their business and operations.  All of such insurance is
in full force and effect.

                  SECTION 3.18.  Capitalization  and  Subsidiaries.  The capital
stock of the Borrower  and of each  Subsidiary  of the Borrower  (other than any
Excluded  Subsidiary)  has  the  classes,  par  values,  authorized  shares  and
outstanding  shares set forth on Schedule 3.18. All of the outstanding shares of
capital  stock of the  Borrower  and of each  Subsidiary  are  duly and  validly

calls,  options,  contracts or other  agreements  of any kind,  issued,  made or
granted to or with any Person under which the Borrower or any  Subsidiary may be
obligated to issue,  sell,  purchase,  retire or redeem or otherwise  acquire or
dispose  of any  equity  securities  of the  Borrower  or  any  Subsidiary.  The
ownership  interests  in the  Borrower or any  Subsidiary  are as  indicated  on
Exhibit A to the Pledge Agreement.

                  SECTION 3.19.  Subsidiaries  and Joint Ventures.  Set forth on
Schedule  3.19 is a list of each  Subsidiary  and Joint Venture of the Borrower,
the state in which each such  Subsidiary or Joint Venture is organized and is in
good  standing  and the  states  in which it is in good  standing  as a  foreign
corporation.

                  SECTION 3.20. Indentures. No "Event of Default" (as defined in
any  Indenture)  or event which with the giving of notice or passage of time, or
both, would constitute such an Event of Default, has occurred and is continuing.

                              CONDITIONS FOR LOAN

                  The  obligation of Lender to make the Loans to the Borrower on
the Funding Date is subject to the accuracy in all  respects,  as of the Funding

other Loan  Documents,  to the performance by the Borrower of its obligations to

to be perfected or to have its intended  priority,  or any party  thereto  other
than Lender  shall  contest the  validity of any Lien  granted  under,  or shall
disaffirm its obligations under any Loan Document; or

                  (m) a judgment or judgments for the payment of money in excess

Documents,  all of the rights and remedies of a secured  party under the Uniform
Commercial  Code as in  effect in all  jurisdictions  where  the  Collateral  is
located or other  applicable  laws,  all of which rights and  remedies  shall be
cumulative,  and none exclusive,  to the extent permitted by law. In addition to
all such  rights  and  remedies,  the sale,  lease or other  disposition  of the
Collateral,  or any part thereof,  by Lender after the occurrence of an Event of
Default  may be for cash,  credit or any  combination  thereof,  and  Lender may
purchase  all or any part of the  Collateral  at public or, if permitted by law,
private sale, and in lieu of actual payment of such purchase price,  may set off
the amount of such purchase price against the Obligations  then owing. Any sales
of the  Collateral  may be adjourned  from time to time with or without  notice.
Lender  may,  in its sole  discretion,  cause  the  Collateral  to remain on the
Borrower's  premises,   at  the  Borrower's  expense,   pending  sale  or  other
disposition of the Collateral. Lender shall have the right to conduct such sales
on the Borrower's  premises,  at the Borrower's expense,  or elsewhere,  on such
occasion or occasions as Lender may see fit.

                  SECTION  8.05  Sale or  Other  Disposition  of  Collateral  by
Lender.  Any  notice  required  to be given by Lender of a sale,  lease or other
disposition  or other  intended  action by  Lender  with  respect  to any of the
Collateral  which is given in accordance with the provisions of Section 9.01, at
least ten (10) Business Days prior to such proposed action shall constitute fair
and  reasonable  notice to the  Borrower of any such  action.  The net  proceeds
realized by Lender upon any such sale or other disposition,  after deduction for
the expense of retaking,  holding,  preparing for sale,  selling or the like and
the  reasonable  attorneys'  fees and  legal  expenses  incurred  by  Lender  in
connection therewith, shall be applied as provided herein toward satisfaction of
the  Obligations.  Lender shall account to the Borrower (and promptly pay to the
Borrower) for any surplus realized upon such sale or other disposition,  and the
Borrower  shall  remain  liable for the the full amount of any  deficiency.  The
commencement of any action, legal or equitable, or the rendering of any judgment
or decree for any deficiency shall not affect Lender's  security interest in the
Collateral. The Borrower agrees that Lender has no obligation to preserve rights
to the Collateral against any other parties.

                  SECTION  8.06.   Lender  Not  Liable.   Lender  shall  not  be
responsible or liable for any shortage, discrepancy, damage, loss or destruction
of any part of the Collateral or of any instrument  received in payment therefor
or for any damages  resulting  therefrom (except to the extent the same shall be
finally  adjudicated  or otherwise  conclusively  determined to have been caused
solely by gross negligence or willful  misconduct of Lender).  Lender shall not,
under any circumstances or in any event  whatsoever,  have any liability for any
error or omission of any kind made in the  settlement,  collection or payment of
any  of  the  Collateral  (except  to the  extent  the  same  shall  be  finally
adjudicated or otherwise  conclusively  determined to have been caused solely by
gross negligence or willful  misconduct of Lender).  The costs of collection and
enforcement,   including  but  not  limited  to  reasonable   counsel  fees  and
out-of-pocket  expenses,  shall be borne solely by the Borrower whether the same
are incurred by Lender or the Borrower.

                  SECTION 8.07. Right of Set-off.  In addition to any rights and
remedies of Lender provided by law,  Lender shall have the right,  without prior
notice  to the  Borrower  or any  Subsidiary  (except  as  may  be  required  by
applicable  law),  upon the occurrence and during the continuance of an Event of
Default,  to set-off and apply against the amount of any Obligation that is then
due and payable,  and to hold for set-off and  application  against  Obligations
that will subsequently  become due and payable (and to set-off and apply against
the  amount  of such  Obligation  as it  becomes  due and  payable,  whether  in
accordance with its terms or by acceleration,  demand or otherwise),  any amount
owing from Lender or any  Affiliate  of Lender to the  Borrower.  Lender  agrees
promptly to notify the Borrower after any such set-off and  application  made by
Lender or any Affiliate of Lender; provided that the failure to give such notice
shall not affect the  validity of such  set-off and  application.  The  Borrower
hereby agrees that the foregoing  provisions  are intended to be construed so as
to satisfy the  requirements  of Section 553 of the Federal  Bankruptcy  Code or
amendments  thereto  (including  any  requirement  of mutuality  of  obligations
therein).


                                   ARTICLE IX
                                  MISCELLANEOUS

                  SECTION  9.01.  Notices.   Notices  and  other  communications
provided  for herein  shall be in writing  and shall be  delivered  by a courier
service of  recognized  standing  (specifying  next Business Day delivery) or by
hand  delivery,  or by registered or certified  mail,  postage  prepaid,  return
receipt requested or by telecommunications  device capable of creating a written
record,  addressed, if to the Borrower, at: 131 National Business Parkway, Suite
100,  Annapolis  Junction,  Maryland 20701,  Attention:  Chief Executive Officer
(telecopy no. 301/617-4279,  confirmation no.  301/617-4200),  and if to Lender,
c/o  AT&T  Capital  Corporation/Capital  Markets  Division,  44  Whippany  Road,
Morristown, NJ 07962-1983,  Attention: Vice President Credit (telecopy no. (973)
397-4368,  confirmation  no.  (973)  397-3482,  with  a  copy  to  AT&T  Capital
Corporation/  Capital  Markets  Division at 44  Whippany  Road,  Morristown,  NJ
07962-1983,  Attention: Chief Counsel (telecopy no. (973) 397-3165, confirmation
no. (973)  397-4189).  All notices and other  communications  given to any party
hereto in accordance  with the provisions of this  Agreement  shall be deemed to
have been given (a) five days after mailing in the United States mails when sent
by registered or certified mail, postage prepaid,  return receipt requested,  or
(b) upon receipt, if by courier service, by hand delivery or any above described
telecommunications  device,  in each case addressed to such party as provided in
this Section or in  accordance  with the latest  unrevoked  direction  from such
party.

                  SECTION 9.02. No Waivers;  Amendments. (a) No failure or delay
of Lender to exercise any right hereunder or under any other Loan Document shall
operate as a waiver  thereof,  nor shall any single or partial  exercise  of any
such right,  preclude any other or further  exercise  thereof or the exercise of
any other right.  No waiver of any provision of this Agreement or any other Loan
Document nor consent to any  departure by the  Borrower  therefrom  shall in any
event be effective unless the same shall be in writing and signed by Lender, and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. No notice or demand on the Borrower in any case
shall  entitle the Borrower to any other or further  notice or demand in similar
or other circumstances.

                  (b) Neither this Agreement nor any other Loan Documents may be
amended or modified  except  pursuant to an agreement or  agreements  in writing
executed by the Borrower and Lender.

                  SECTION 9.03.  Governing Law and Jurisdiction.  THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS  SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE  INTERNAL  LAWS OF THE  STATE OF NEW YORK  WITHOUT  GIVING  EFFECT TO ANY
CONFLICTS  OF  LAWS   PRINCIPLES.   THE  BORROWER  AND  LENDER  CONSENT  TO  THE
JURISDICTION  OF ANY LOCAL,  STATE OR FEDERAL  COURT LOCATED IN THE STATE OF NEW
JERSEY  AND  WAIVE  ANY  OBJECTION  RELATING  TO  IMPROPER  VENUE OR  FORUM  NON
CONVENIENS TO THE CONDUCT OF ANY PROCEEDING BY SUCH COURT.

                  SECTION 9.04.  Expenses;  Documentary Taxes. The Borrower will
pay all reasonable  out-of-pocket expenses incurred by Lender in connection with
the negotiation, preparation and execution of the Loan Documents (whether or not
the transactions  contemplated hereby shall be consummated),  the administration
of the Loan Documents, the creation,  perfection,  priority or protection of the
Liens  in the  Collateral,  and the  enforcement  of the  rights  of  Lender  in
connection  with this  Agreement,  any other Loan  Documents or the  Collateral,
including all reasonable  attorneys'  fees and related  expenses and costs.  The
Borrower agrees that it shall indemnify Lender from and hold it harmless against
any documentary taxes or similar assessments or charges made by any Governmental
Authority by reason of the execution and delivery of this Agreement or any other
Loan Document.

                  SECTION 9.05.  Equitable Relief. The Borrower recognizes that,
in the  event  that  it  fails  to  perform,  observe  or  discharge  any of its
obligations or liabilities under this Agreement, or any other Loan Document, any
remedy  at law may  prove to be  inadequate  relief to  Lender;  therefore,  the
Borrower  agrees  that  Lender,  if Lender so  requests,  shall be  entitled  to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

                  SECTION 9.06.  Indemnification;  Limitation of Liability.  (a)
The Borrower  agrees to protect,  indemnify and hold harmless Lender and each of
its  officers,  Affiliates,   directors,  employees,   attorneys,   accountants,
representatives  and agents  (collectively  called the  "Indemnitees")  from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever  (including,  without  limitation,  the reasonable fees and
disbursements  of counsel for and consultants of such  Indemnitees in connection
with any investigative,  administrative or judicial  proceeding,  whether or not
such Indemnitees shall be designated a party thereto),  which may be imposed on,
incurred by, or asserted against such Indemnitees (whether direct,  indirect, or
consequential  and whether based on any federal or state laws or other statutory
regulations,  including,  without  limitation,  securities,   environmental  and
commercial  laws and  regulations,  under common law or at equitable cause or on
contract  or  otherwise)  in any  manner  relating  to or  arising  out of  this
Agreement or any of the other Loan  Documents,  or any act, event or transaction
related or attendant  thereto,  the agreements of Lender contained  herein,  the
making of Loans,  the management of such Loans or the Collateral  (including any
liability under federal,  state or local  environmental  laws or regulations) or
the use or intended use of the proceeds of such Loans  hereunder  (collectively,
the  "Indemnified  Matters");  provided  that the  Borrower  shall  not have any
obligation  to any  Indemnitee  hereunder  with respect to  Indemnified  Matters
caused by or resulting from the willful  misconduct or gross  negligence of such
Indemnitee  or with  respect  to taxes  imposed  on the Lender on (i) any of its
overall  net  income  and (ii)  franchise  taxes  imposed  on the  Lender by the
jurisdiction  under the laws of which the Lender is organized  or any  political
subdivision  thereof.  To the extent that the undertaking to indemnify,  pay and
hold harmless set forth in the preceding  sentence may be unenforceable  because
it is violative of any law or public policy,  the Borrower shall  contribute the
maximum  portion which it is permitted to pay and satisfy under  applicable law,
to the payment  and  satisfaction  of all  Indemnified  Matters  incurred by the
Indemnitees.

                  (b) To the extent permitted by applicable law, no claim may be
made  by  the  Borrower  or  any  other  Person  against  Lender  or  any of its
Affiliates,  directors,  officers,  employees,  agents, attorneys,  accountants,
representatives  or  consultants  for any special,  indirect,  consequential  or
punitive  damages in respect  of any claim for breach of  contract  or any other
theory of liability  arising out of or related to the transactions  contemplated
by any of the  Loan  Documents  or any  act,  omission  or  event  occurring  in
connection therewith; and the Borrower hereby waives, releases and agrees not to
sue upon any claim for any such  damages,  whether or not accrued and whether or
not known or  suspected  to exist in its  favor.  Neither  Lender nor any of its
Affiliates,  directors,  officers,  employees,  agents, attorneys or consultants
shall be liable for any action  taken or omitted to be taken by it or them under
or in  connection  with any of the Loan  Documents,  except for its or their own
gross negligence or willful misconduct.

                  SECTION  9.07.  Survival of  Agreements,  Representations  and
Warranties,  etc. All  warranties,  representations  and  covenants  made by the
Borrower  in any Loan  Document  survive  the  execution  and  delivery  of this
Agreement and the other Loan Documents and the making of the  Obligations  until
repayment in full of all Obligations.

                  SECTION 9.08. Successors and Assigns. (a) The Borrower may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of Lender. This Agreement shall be binding upon and inure to the
benefit of the Borrower and Lender and their respective successors and permitted
assigns. Without limiting the generality of the foregoing, the Lender shall have
the  right  to  assign  any of  its  rights  hereunder  or  delegate  any of its
obligations hereunder, in whole or in part and/or all of its rights and interest
under the Loan Documents as security therefor to any affiliate,  or to any bank,
financial  institution  or financing  company  which in the  ordinary  course of
business accepts  assignments of loans or assumes obligations to make loans from
third parties,  and in furtherance thereof to provide to any such prospective or
actual assignee financial or other information  relating to the Borrower and the
transactions contemplated hereby.

                  (b) Without  limiting the  generality  of the  foregoing,  the
Lender  shall  have  the  right  in its  sole  discretion  to  sell  one or more
participations  in the Note and the Loan Documents  without notice to or consent
of the  Borrower to any  affiliate,  or to any bank,  financial  institution  or
financing  company  which  in  the  ordinary  course  of  its  business  accepts
assignments  of loans or assumes  obligations  to make loans from third parties,
and in connection  therewith,  to provide such  participants  with financial and
other  information  and copies of  documents  relating to the  Borrower  and the
transactions contemplated hereby.

                  SECTION  9.09.  Severability.  In case  any one or more of the
provisions  contained  in this  Agreement  or any other Loan  Document  shall be
invalid,  illegal or  unenforceable in any respect,  the validity,  legality and
enforceability  of the remaining  provisions  contained herein and therein shall
not in any way be affected or impaired thereby.

                  SECTION  9.10.  Cover  Page,  Table of  Contents  and  Section
Headings. The cover page, Table of Contents and section headings used herein are
for convenience of reference only, are not part of this Agreement and are not to
affect the construction of or be taken into  consideration in interpreting  this
Agreement.

                  SECTION 9.11.  Counterparts.  This Agreement may be signed in
counterparts with the same effect as if the signatures thereof and hereto were
upon the same instrument.

                  SECTION 9.12.  Application  of Payments.  Notwithstanding  any
contrary  provision  contained  in this  Agreement  or in any of the other  Loan
Documents,  upon the  occurrence  and  during  the  continuance  of any Event of
Default,  the Borrower irrevocably waives the right to direct the application of
any and all payments at any time or times thereafter received by Lender from the
Borrower or with respect to any of the Collateral,  and the Borrower does hereby
irrevocably agree that Lender shall have the continuing exclusive right to apply
and  reapply  any and all  payments  received  at any time or times  thereafter,
whether with respect to the Collateral or otherwise,  against the Obligations in
such manner as Lender may reasonably deem advisable,  notwithstanding  any entry
by Lender upon any of its books and records.

                  SECTION 9.13. Marshalling; Payments Set Aside. Lender shall be
under no obligation to Marshall any assets in favor of the Borrower or any other
party or against or in payment of any or all of the  Obligations.  To the extent
that the Borrower  makes a payment or payments to Lender or Lender  enforces its
security  interests  or  exercises  its  rights of setoff,  and such  payment or
payments or the proceeds of such  enforcement  or setoff or any part thereof are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then to the
extent of such recovery,  the obligation or part thereof originally  intended to
be satisfied  shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

                  SECTION 9.14. SERVICE OF PROCESS. THE BORROWER WAIVES PERSONAL
SERVICE OF ANY PROCESS UPON IT AND,  CONSENTS  THAT ALL SERVICE OF PROCESS SHALL
BE MADE BY REGISTERED MAIL, RETURN RECEIPT  REQUESTED,  DIRECTED TO THE BORROWER
AT THE ADDRESS  INDICATED IN SECTION 9.01 AND SERVICE SO MADE SHALL BE DEEMED TO
BE COMPLETED FIVE (5) DAYS AFTER SAME SHALL HAVE BEEN POSTED AS AFORESAID.

                  SECTION  9.15.  WAIVER OF JURY TRIAL.  THE BORROWER AND LENDER
EACH  WAIVES ANY RIGHT TO HAVE A JURY  PARTICIPATE  IN  RESOLVING  ANY  DISPUTE,
WHETHER  SOUNDING  IN  CONTRACT,  TORT,  OR  OTHERWISE,  BETWEEN  LENDER AND THE
BORROWER  ARISING  OUT OF,  CONNECTED  WITH,  RELATED  TO OR  INCIDENTAL  TO THE
RELATIONSHIP  ESTABLISHED  BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT OR ANY OTHER INSTRUMENT,  DOCUMENT OR AGREEMENT  EXECUTED OR
DELIVERED IN  CONNECTION  THEREWITH OR THE  TRANSACTIONS  RELATED  THERETO.  THE
BORROWER AND LENDER EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND,
ACTION OR CAUSE OF ACTION  SHALL BE  DECIDED BY COURT  TRIAL  WITHOUT A JURY AND
THAT EITHER MAY FILE AN ORIGINAL  COUNTERPART  OR A COPY OF THIS  AGREEMENT WITH
ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER
OF THEIR RIGHT TO TRIAL BY JURY.

                  SECTION 9.16.  Confidentiality.  The parties hereto  recognize
and acknowledge  that, in connection with the transactions  contemplated by this
Agreement and the other Loan Documents, Lender necessarily will need to acquire,
consider  and  analyze  certain  information  about the  Borrower  and which the
Borrower  regards as valuable and confidential and identified in writing as such
by Borrower (the  "Confidential  Information").  The Lender agrees that it shall
use  the  Confidential  Information  solely  for  purposes  of the  transactions
contemplated  by this  Agreement  and the  other  Loan  Documents  and  that the
Confidential  Information  will be kept  confidential  by Lender and that Lender
will not disclose any of the Confidential  Information to any Person;  provided,
however,  that  such  confidentiality  obligation  shall  not  apply  to (i) any
information  disclosed to Persons  employed by or expected to become  engaged in
evaluating,  approving,  structuring,  auditing  or  administering  the Loans or
Obligations  hereunder  who agree to comply with this Section  9.16,  including,
without  limitation,   the  Lender's   representatives,   attorneys,   advisors,
accountants,  and  rating  agencies,  (ii) any  information  which is or becomes
available  to  the  Lender  from  a  source  other  than  the  Borrower,  or its
Affiliates,  (iii) any information  which is or becomes  available to the public
other  than  as  a  result  of  disclosure  by  Lender  or  its  above-described
representatives  or agents,  (iv) any  information  required or requested by any
governmental  agency or representative  thereof or pursuant to legal process, or
(v) any information in connection with the exercise of any remedy under the Loan
Documents; and provided,  further, that nothing herein shall prevent Lender from
disclosing such information to any bona fide assignee, transferee or participant
or prospective  assignee,  transferee or participant of any of their  respective
representatives  that have agreed to comply with this Section 9.16 in connection
with  the  contemplated  assignment  or  transfer  of  any  Loans  hereunder  or
participation therein.
                  SECTION 9.17. Entire Agreement, etc. This Agreement (including
all  schedules  and  exhibits  referred to herein),  the Note and all other Loan
Documents constitute the entire contract between the parties hereto with respect
to the subject matter hereof and thereof and shall  supersede and take the place
of any other  instrument  purporting  to be an agreement  of the parties  hereto
relating to such subject matter.
