Item 5.  Other Events.


Asset Acquisition

         On October 17, 1997 (the "Closing  Date"),  WinStar Switch  Acquisition
Corp.  ("WSAC"),  a wholly  owned  subsidiary  of WinStar  Communications,  Inc.
("WinStar",  and together  with WSAC,  the  "WinStar  Parties"),  consummated  a
purchase  ("Asset  Acquisition")  of  certain   telecommunications  assets  (the
"Assets") from US ONE  Communications  Corp. ("US ONE"),  US ONE  Communications
Services Corp. and US ONE  Communications of New York, Inc. (each individually a
"Seller" and  collectively,  the  "Sellers"),  pursuant to the terms of an asset
purchase agreement ("Asset Purchase Agreement"). The Assets included 12 Lucent 5
ESS-2000  switching systems and other non-switch  assets.  The Asset Acquisition
required  and  received  the  approval of the United  States  Bankruptcy  Court,
District of Delaware ("Court"),  because Sellers are debtors in possession under
Chapter 11 of the United States Bankruptcy Code of 1978, as amended.

         The  aggregate  purchase  price paid for the  Assets was  approximately
$81.1  million,  of which  approximately  $61.1  million was paid in cash at the
closing  and $20  million  of which is payable  by the  WinStar  Parties in cash
and/or shares of the common stock of WinStar,  at WinStar's  discretion,  on the
effective date of Sellers' confirmed plan of reorganization.

         There exists no material  relationship  between the Sellers and WinStar
or any of their respective affiliates.

Financing the Asset Acquisition

         In order to finance the cash portion of the  purchase  price and to pay
certain expenses, on the Closing Date, WSAC borrowed $62.25 million (the "Loan")
from  Salomon  Brothers  Holding  Company  Inc and Credit  Suisse  First  Boston
(together,  the "Lenders").  The Loan maturity date is April 22, 1998; provided,
however,  that WSAC must prepay the Loan (or portions thereof) with the proceeds
of any sale by it of the  purchased  Assets  and  with  proceeds  obtained  from
certain  financings.  The Loan is  guaranteed  by WinStar  and is secured by the
telecommunications  switches  and  related  equipment,  inventory  and  software
included in the Assets.

     A. Sellers have developed a nationwide  telecommunications  network capable
of providing local and long distance  telecommunications  services  (hereinafter
referred to as the "Business"); and

     B. Sellers desire to sell and Purchaser  desires to purchase certain assets

is  willing  to assume  certain  obligations  and  liabilities  relating  to the
purchased  assets,  all on the terms and subject to the  conditions set forth in

         NOW, THEREFORE, the parties hereto agree as follows:

indemnify  Sellers  from any and all claims or demands in respect of the Assumed
Liabilities   from  and  after  the   Closing;   provided,   however  that  such
indemnification  obligations with respect to any Designated Contract shall cease
upon the assignment of such  Designated  Contract to a third party under Section
5.3.2.

                           ARTICLE III. PURCHASE PRICE

         3.1 Purchase  Price.  In addition to assuming the Assumed  Liabilities,
Purchaser or its Designees  will pay for the Purchased  Assets and the covenants
of Sellers included herein an aggregate purchase price of U.S. $100 million (the
"Purchase Price"), payable as follows:

     (a) $80 million on the Closing Date (as defined in Section 4.1 hereof),  by
wire  transfer or certified or official bank check to the order of US ONE ("Cash
Portion")   provided,   however,   that  if  the  Sellers  have  not   completed
construction, installation of generators and obtained a certificate of occupancy
for each Switch Site as set forth in Sections  5.1.12 and 5.7 hereof,  an amount
equal to the cost  allocable to each  incomplete  Switch  Site,  as set forth in
Schedule 5.1.12(c),  shall be paid into escrow  ("Construction Escrow Portion"),
to be held by the  Escrow  Agent  in  accordance  with the  Construction  Escrow
Agreement (as defined in Section 3.4.2 hereof);

     (b)  $16  million  on the  effective  date  ("Plan  Effective  Date")  of a
confirmed Chapter 11 Plan of Reorganization of Sellers ("Plan"), by the issuance
by WinStar of shares of its Common Stock ("WCI Shares"), valued for this purpose
at the average of the last sale  prices of the WCI Shares on the twenty  trading
days ending two business  days  preceding  the Plan  Effective  Date ("Plan Date
Market  Value"),  to be  issued  pursuant  to and in  accordance  with  the Plan
("Initial Share Portion"); and

     (c) $4 million on the Plan  Effective Date by issuance of WCI Shares valued
at the Plan Date Market  Value and  delivered  into  escrow  pursuant to Section
3.4.1 hereof  ("Escrow  Share  Portion"  and,  together  with the Initial  Share
Portion,  the "Share Portion"),  also to be issued pursuant to and in accordance
with the Plan and to be held and  distributed  in  accordance  with the  "Escrow
Agreement" (as defined in Section 3.4.1).

     Notwithstanding the foregoing, in Purchaser's sole and absolute discretion,
it shall have the right to pay any or all of the $20 million  represented by the
Share  Portion in cash.  To the  extent  that cash is used in lieu of all or any
portion of the Escrow  Share  Portion,  then such cash shall be paid into escrow
and held in accordance with the terms of the Escrow Agreement.

         3.2 Allocation of Purchase Price.  Promptly following the Closing Date,
the Purchase Price shall be allocated among the Purchased Assets in such amounts
as shall be  specified  in a schedule  to be prepared  by the  Purchaser,  which
allocation,  absent manifest error,  shall be binding upon the Purchaser and the
Sellers,  each  of  which  agrees  to  report  the  effect  of the  transactions
contemplated  hereby  on all  applicable  tax  returns  or  filings  in a manner
consistent  with such  schedule.  Each Seller hereby  assumes  liability for and
shall pay all sales, transfer and similar taxes incurred as a result of the sale
of the Purchased Assets to Purchaser.

         3.3 Application of Purchase Price.  Upon receipt of the Purchase Price,
Sellers shall be obligated to (i) cure the defaults under the Assumed  Contracts
arising or  existing  prior to the  Closing  Date as set forth on  Schedule  3.3
hereto and (ii) at such time as Sellers are obligated to do so under  applicable
bankruptcy law, pay all post-petition expenses of the Sellers, including fees of
the Escrow Agent under the Escrow  Agreement and  Construction  Escrow Agreement
and any taxes or other expenses relating to this Agreement.

forth on Schedule 5.1.6, Sellers own the entire right, title and interest in and
to the  Intellectual  Property and Intangibles  included in the Purchased Assets

trade  names,   trademark   registrations  and   applications,   service  marks,

any of the Intellectual  Property or Intangibles are valid and subsisting,  have
been properly  maintained and, to the knowledge of Sellers,  neither Sellers nor
any other persons are in default or violation thereunder.

                  5.1.7  Condition  of  Certain  Assets.   The  physical  assets
comprising part of the Purchased Assets are, and on the Closing Date will be, in
good operating condition and repair,  ordinary wear and tear excepted,  suitable
for the purposes used for the Business.

                  5.1.8  Permits,  Licenses and Tariffs.  The Permits  listed on

conduct the Business substantially in the manner heretofore conducted.

                  5.1.9    Employee Plans.

     (a) The Sellers do not maintain any "employee  benefit plans" and "employee
welfare  plans",  as  defined  in this  Sections  3(1) and 3(3) of the  Employee
Retirement Income Security Act of 1974 ("ERISA") respectively and, except as set
forth on Schedule 5.1.9,  have not maintained,  contributed to, been required to
contribute to, or been a party to or a participating  employer in, any "employee
pension  benefit  plan," as  defined  in Section  3(2) of ERISA,  including  any
multiemployer  employee pension benefit plan (the "Employee Benefit Plans"). The
Sellers are not parties to any collective bargaining or other labor agreements.

     (b) The Employee  Benefit Plans (i) are qualified to the extent required by
law under  Section 401 of the Internal  Revenue Code of 1986,  as amended and to
the best knowledge of Sellers there exists no fact which would adversely  affect
the qualified  status of any such Employee Benefit Plan; (ii) have been operated
and administered in all material respects in accordance with ERISA, the Internal
Revenue  Code and all  other  applicable  law;  (iii)  have not  engaged  in any
transactions  (as such term is defined for  purposes  of ERISA and the  Internal
Revenue Code);  (iv) have not, since the last annual report filed,  been amended
so as to materially

                                        6

<PAGE>



increase benefits  thereunder or experienced a material increase (more than 20%)
in the number of participants covered thereunder; and (v) v if terminated on the
date hereof, would not give rise to liability under Title IV of ERISA.

     (c) Each Seller, at all times, has complied with all applicable  provisions
of the Employee Benefit Plans and is not in default thereunder. Full payment has
been made of all amounts  which any Seller is required to pay under the terms of
each of the Employee Benefit Plans as a contribution or premium to or in respect
of such plans as of the last day of the most  recent  fiscal year of each of the
Employee  Benefit  Plans  ended  prior to the date of this  Agreement,  any such
contribution  has been  accrued as a  liability  on the books of the Sellers and
none of the Employee  Benefit  Plans nor any trust  established  thereunder  has
incurred  and  "accumulated  funding  deficiency"  (as defined in Section 302 of
ERISA and Section 412 of the Internal Revenue Code),  whether or not waived with
respect to the most recent  fiscal year of each of the  Employee  Benefit  Plans
ended prior to the date of this Agreement.

     (d) There are no pending, anticipated or, to Sellers' knowledge, threatened
claims against or otherwise  involving any of the Employee Benefit Plans, or any
fiduciary  thereof,  by or on behalf of such plans,  any employee or beneficiary
covered  under the plans or  otherwise  involving  the plans (other than routine
claims for benefits). There is no judgment, decree, injunction, rule or order of
any court,  governmental  body,  commission,  agency or  arbitrator  outstanding
against or in favor of any plan or any fiduciary thereof.

                  5.1.10  Environmental  Matters;  Health  and  Safety and Other
Laws.  The Sellers are, and on the Closing Date will be, in material  compliance
with all  federal,  state and  local  laws,  regulations,  permits,  orders  and
decrees,  including those relating to protection of the environment and employee
health and safety ("Applicable Requirements"). The Sellers have not received any
written notice to the effect that their  operations  are not in compliance  with
any  of  the  Applicable   Requirements  or  the  subject  of  any  governmental
investigation  evaluating  whether any remedial action is needed to respond to a
release of any toxic or hazardous waste or other substance  (including petroleum
products)  into the  environment  and no Seller  knows of any facts  which could
constitute the basis for any thereof.

                  5.1.11   Investor Representations.

     (a) The WCI Shares  which may be issued  pursuant  to  Section  3.1 of this
Agreement  will not be registered  under the  Securities Act of 1933, as amended
("Securities Act").  Accordingly,  unless and until Sellers deliver to WinStar a
"No Action Letter" from the Securities and Exchange  Commission or a final order
of the  Bankruptcy  Court  providing  that the WCI  Shares  which  may be issued
herewith will be exempt from registration under the Securities Act and any state
law pursuant to Section 1145 of the  Bankruptcy  Code and such WCI Shares may be
issued  without  any  restrictive  legend,  the WCI  Shares  will  bear a legend
indicating  that  they are  "restricted"  and will not be able to be sold in the
open market or otherwise  transferred,  pledged or hypothecated  until such time
that the resale and transfer of same is registered  under the  Securities Act or
until such time as the WCI  Shares  are  saleable  in  accordance  with Rule 144
promulgated  under the Securities Act or some other exemption from  registration
provided  under  the  Securities  Act or the  Bankruptcy  Code.  WinStar  is not
obligated to file any registration statement with respect to the WCI Shares.

     (b) Sellers  recognize  that an  investment  in WCI Shares  involves a high
degree of risk  including,  but not limited to, the risk of economic losses from
WinStar's operations and the total loss of its investment.


                                        7

     (c)  Sellers  have  been  given  access  to full and  complete  information
regarding  WinStar and have utilized such access to the extent deemed  necessary
for the purpose of obtaining  information,  and its officers and directors  have
either met with or been given  reasonable  opportunity  to meet with officers of
WinStar for the purpose of asking  questions of, and  receiving  answers to such
questions,  from such officers concerning the business and operations of WinStar
and to obtain any additional  information,  to the extent reasonably  available.
Sellers  have  received  copies  of all  reports  filed  by  WinStar  under  the
Securities Exchange Act of 1934 during the past two years.

                  5.1.12 The Sellers have not completed construction,  installed
generators  or obtained  certificates  of occupancy for all of the Switch Sites.
Schedule  5.1.12(a) lists the current status of the  construction and generators
at each of the Switch  Sites.  Schedule  5.1.12(b)  lists the current  status of
certificates  of  occupancy  for each of the Switch  Sites and the date  Sellers
anticipate  receiving  each such  certificate of occupancy.  Schedule  5.1.12(c)
lists the construction, inspections, and other work which has not been completed
and which is necessary to install an operational generator, obtain a certificate
of  occupancy  and  complete  construction  at each of the Switch  Sites and the
maximum cost of completing such work and obtaining such certificate of occupancy
and the timing thereof.  The contractors  identified on Schedule  5.1.12(c) (the
"Identified  Contractors")  have  agreed to  complete  construction  and  obtain
certificates  of occupancy for each of the Switch Sites in  accordance  with the
costs and timing set forth in Schedule 5.1.12(c).

                  5.1.13 There is no liability for pre-Closing  actions taken by
Sellers  under the "22 Cage  Rental  Agreements  between  US ONE  Communications
Services of New York,  Inc. and New York Telephone  Company"  listed on Schedule
5.3.2 ("Collocation Schedules").

         5.2   Indemnification.   The  Sellers  shall,  jointly  and  severally,
indemnify  and hold harmless  Purchaser  from and against,  and shall  reimburse
Purchaser or WinStar, solely through the return to Purchaser of all or a portion
of the  Escrow  Share  Portion of the  Purchase  Price (or the cash which may be
deposited  in  escrow  in lieu  thereof)  pursuant  to the  terms of the  Escrow
Agreement,  for any Damages (as  hereinafter  defined)  which may be  sustained,
suffered or incurred by Purchaser  or WinStar,  whether as a result of any third
party claims or otherwise,  and which arise or result from or in connection with
or  are   attributable   to  the  breach  of  any  of  a   Sellers'   covenants,
representations,  warranties,  agreements, obligations or undertakings contained
in this  Agreement.  "Damages" as used in this Agreement means the dollar amount
of any loss,  damage,  expense or  liability,  (including,  without  limitation,
reasonable attorneys' fees) sustained,  suffered or incurred by the Purchaser or
WinStar,  reduced by any amounts actually  received by Purchaser or WinStar (net
of any deductibles, fees and expenses, but excluding any premiums) from: (i) any
insurance  proceeds received by Purchaser or WinStar in respect of such damages;
and (ii) any  recovery  made by  Purchaser  or WinStar from a third party (other
than Sellers) in respect thereof.  Notwithstanding the foregoing,  Sellers shall
not be required to indemnify  Purchaser or WinStar under this Section 5.2 unless
the aggregate of all amounts for which  indemnity would otherwise be due against
Sellers exceeds $100,000,  but in such event, the Sellers shall pay the party to
be  indemnified  all  amounts for which  indemnity  is due  including  the first
$100,000 thereof.  To the extent Sellers are required to indemnify  Purchaser or
WinStar, the Purchase Price shall be deemed to be reduced by such amount.

         5.3      Designees and Designated Contracts.

                  5.3.1  Designees.  Subject to the  approval of the  Bankruptcy
Court, at any time prior to the Closing Date,  Purchaser shall have the right to
assign  to  third  parties  ("Designees")  the  right  to  purchase  such of the
Purchased Assets as Purchaser shall determine. If any such assignment

                                        8

<PAGE>



is made, the Designees shall assume the Assumed  Liabilities with respect to the
Purchased Assets to be purchased by them. Sellers shall cooperate with Purchaser
in all reasonable respects with respect to any such assignment.

                  5.3.2 Designated Contracts. Schedule 5.3.2 lists all contracts
and agreements  ("Designated  Contracts") which on or after the Closing Date and
through and including  March 20, 1998,  upon written  notice by the Purchaser to
Sellers and to each party to any such Designated  Contract,  will be assigned by
the Sellers to either the  Purchaser or,  subject to approval of the  Bankruptcy
Court  pursuant  to ss.365 of the United  States  Bankruptcy  Code  ("Bankruptcy
Code"), a designee of the Purchaser.  Prior to March 20, 1998, without the prior
written  consent of the  Purchaser,  Sellers will not seek  authority to reject,
will not consent to the rejection  of, and will use best efforts,  including but
not limited to filing any appropriate  pleadings to prevent the deemed rejection
of the contracts and agreements listed on Schedule 5.3.2.  Promptly upon written
notice by the Purchaser to Sellers that the Purchaser  desires Sellers to assume
and  assign  one or more  of the  Designated  Contracts  to the  Purchaser  or a
designee of the Purchaser,  Sellers will file a motion with the Bankruptcy Court
seeking  authorization  pursuant to section 365 of the  Bankruptcy  Code of such
assumption and assignment.  Until  assumption and assignment or rejection of the
Designated  Contracts,  Sellers  will  comply  with the  provisions  of  section
365(d)(3) or 365(d)(10) of the Bankruptcy Code , as applicable,  with respect to
each Designated  Contract.  As soon as practicable  after Closing,  Sellers will
provide to the Purchaser a schedule of regular,  ongoing  obligations  to become
due under the  Designated  Contracts  with  respect  to  obligations  arising or
incurred  after the Closing and Sellers will provide as promptly as  practicable
to the Purchaser any other invoices,  bills and other requests for payment under
the  Designated  Contracts  received  with  respect  to  obligations  arising or
incurred  after the  Closing  .  Purchaser's  obligations  with  respect  to the
Designated Contracts,  until specifically assumed will be solely to make payment
on behalf of  Sellers  (except as  provided  in  section  5.11) for the  payment
obligations  arising and incurred  after  Closing  (excluding  pre-Closing  cure
payments)  and before such  Designated  Contracts are assigned to Purchaser or a
third party  designee.  Purchaser will pay any such  liabilities and obligations
incurred and arising from and after Closing on behalf of Sellers directly to the
other  party  to the  Designated  Contract  pursuant  to  section  2.1  of  this
Agreement.

                  5.6.2 Motion to Approve Sale.  Sellers shall file motions with
the Bankruptcy Court by 5:00 p.m. (New York City time) on Wednesday,  October 1,
1997, to approve the sale of the Purchased Assets pursuant to ss.ss.  363(b) and

Sellers' creditors,  all parties having or claiming an interest in the Business,
to the U.S.  Trustee and all other parties in interest in accordance  with Rules
6004 and 6006 of the Bankruptcy  Rules in connection with such motions.  As part
of the motion to approve the sale,  Sellers  shall  request that the  Bankruptcy
Court's  order  provide that (i) it retains  jurisdiction  through and including
March 20,  1998,  to  entertain  motions  to  authorize  Sellers  to assign  the
Designated  Contracts  to  Purchaser's  designees  pursuant  to  ss.  365 of the
Bankruptcy Code, (ii) Purchaser and WinStar shall not be deemed to be successors
to Sellers for any purpose, including claims arising out of the Employee Benefit

Shares  which  may  be  issued  pursuant  to a  Section  3.1 of  this  Agreement
subsequently  are distributed to the creditors or equity security holders of any
of the  Sellers  in  exchange  for a claim  against  or  interest  in any of the
Sellers, Purchaser and WinStar shall be deemed to be persons that participate in

the plan or plans of the  Sellers as provided in  ss.1125(e)  of the  Bankruptcy
Code and (iv) the transfer of the  Purchased  Assets to Purchaser is not subject
to  taxation  under any state or local law  imposing a stamp or  similar  tax in

                  5.6.3 Motions to Approve  Assignment of Designated  Contracts.
Within five business days after Purchaser designates in writing,  whether all or
any one of the  Designated  Contracts  are to be  assigned to  Purchaser  or its
designees,  Sellers shall assign such Designated Contracts to Purchaser, or file
motions with the Bankruptcy  Court to approve the assignment of such  Designated
Contracts to such designees and give notice of such motions as may be required.

                  5.6.4  Retention of  Jurisdiction  in the Plan.  Except as set

Contracts to Purchaser's  designees  pursuant to ss. 365 of the Bankruptcy Code.
In the event that the Bankruptcy  Court refuses to confirm a plan based in whole
or in part on the foregoing retention of jurisdiction  provision,  Sellers shall
be entitled to propose a plan of  reorganization  which omits such  retention of
jurisdiction provision,  provided, however that Sellers shall not seek or obtain
confirmation of such plan of reorganization on or before March 20, 1998.

         5.7 Completion of Construction. On or prior to the Closing Date Sellers
will  complete   construction  of  the  Switch  Sites  in  accordance  with  the

                                       11

<PAGE>



on  Schedules  5.1.12(a),  5.1.12(b) and  5.1.12(c) at  no  cost to Purchaser or
WinStar.  If Sellers have not completed such construction in accordance with the
plans and  specifications  set forth in the  motions  and the  Bankruptcy  Court
orders authorizing such completion and obtained the certificates of occupancy by
the Closing Date,  Sellers shall cause the  Identified  Contractors to use their
best  efforts  to  complete   construction,   install   generators   and  obtain
certificates of occupancy as soon as possible;  provided,  however, that Sellers
shall be  entitled  to draw the cost of such work,  to be paid  directly  to the
Identified  Contractors,  from  the  Construction  Escrow  Account  as  provided
therein.  The Sellers will use their best  efforts to complete the  construction
and obtain a  certificate  of  occupancy  for the Switch Site located in Boston,
Massachusetts on or before the Closing Date or by the Closing Date will contract
with a contractor  (which will be deemed an Identified  Contractor)  to complete
such work and obtain a certificate of occupancy as soon  thereafter as possible.
Sellers shall cause all  certificates of occupancy issued with respect to Switch
Sites after the Closing Date to be issued to the Lessee under the related switch
lease at the time of issuance.  If a certificate  of occupancy  issued after the
Closing Date is issued to Sellers and Purchaser subsequently requests a transfer
of the certificate of occupancy to Purchaser or its designee,  the costs of such
transfer charged by the issuing authority shall be paid by Purchaser.

         5.8 Copies of Agreements.  Sellers will use its best efforts to provide
Purchaser  with a true and  complete  copy of each of the  Agreements  listed on
Schedule  1.1.1  hereof on or before  October 3, 1997,  and shall  provide  such
copies no later than October 13, 1997.

         5.9 Applications for Sellers Permits. Prior to Closing,  Purchaser will
file  applications for "Sellers Permits" with the State Department of Revenue or
a  similar  State  taxing  authority  for each  State in which a Switch  Site is
located and will provide Sellers with a copy of each application.

         5.10  Delivery of Employee  Benefit  Plan  Documentation.  Sellers will
furnish to Purchaser, not less than three days before the Closing Date, true and
complete copies of the following  items, to the extent they exist,  with respect
to each Employee Benefit Plan: (i) each plan document; (ii) each trust document;
(iii)  all   determination   letters  and  other   correspondence   relating  to
qualification of the respective plans under the Internal Revenue Code ; (iv) all
tax returns  and annual  reports;  (v) all  financial  statements;  and (vi) all
actuarial valuations.

         5.11 Collocation Schedules.  Notwithstanding the provisions of Sections
2.1 and 5.3.2,  with  respect  to each of the  Collocation  Schedules  listed on
Schedule 5.3.2,  Purchaser shall have the option until March 20, 1998, to remove
such  Collocation  Schedules from Schedule 5.3.2 and to add any such Collocation
Schedule to Schedule 1.2 as an Excluded  Asset.  If Purchaser  does not elect to
exclude any such Collocation  Schedule,  then such Collocation Schedule shall be
treated as a Designated  Contract  under Section  5.3.2.  If Purchaser  notifies
Sellers  that it  wishes  Sellers  to assume  and  assign  any such  Collocation
Schedule to Purchaser or its Designee, then Sellers shall use their best efforts
to obtain  such  assumption  and  assignment,  or  alternatively  transfer  such
Collocation  Schedules to Purchaser or its Designee as  Intangible  Assets under
Schedule  1.1,  including  filing  and  prosecuting   appropriate  pleadings  to
accomplish such result. If the Bankruptcy Court finds that Sellers' rights under
the  Collocation  Schedules are not assignable or transferable to Purchaser or a
Designee,  then the Collocation Schedules will be deemed to be moved to Schedule
1.2 as Excluded Assets.  Under no circumstances shall Sellers have any liability
for any  additional  costs,  including,  without  limitation,  the  nonrecurring
charges  listed in the  respective  Collocation  Schedules,  under the documents
relating to the Collocation Schedules, nor will Sellers

                                       12

<PAGE>



have any liability to Purchaser or its Designee if the  Bankruptcy  Court denies
transfer or assumption and assignment of Sellers'  rights under the  Collocation
Schedules.

         5.12  Sellers  shall take no  affirmative  action  which shall have the
effect  of  creating  any   post-Closing   obligation  or  liability  under  the
Collocation Schedules.

to the  contrary,  this  Agreement  may be  terminated  at any time prior to the

     (a) Upon the written consent of both Purchaser and the Sellers;

     (b) By Purchaser  in the event  Sellers  shall not, by 5:00 p.m.  (New York

Court in accordance with Sections 5.6.1 and 5.6.2 hereof;

     (d) By  Purchaser  in the event that (i) the  Break-up  Fee,  Upset  Price,

default  cannot  be cured  within a  reasonable  period of time and has not been
waived.

                         ARTICLE IX. BREAK-UP PROVISIONS

         9.1  Specific  Performance.  The parties  recognize  that if  Purchaser
refuses to perform under the  provisions  of this  Agreement,  monetary  damages
alone will not be adequate to compensate the Sellers for their injuries. Sellers
shall  therefore  be  entitled,  in addition to any other  remedies  that may be
available, to obtain specific performance of the terms of this Agreement. If any
action is brought by the  Sellers to enforce  this  Agreement,  Purchaser  shall
waive the  defense  that there is an  adequate  remedy at law. In the event of a
default by  Purchaser  which  results in the  filing of a lawsuit  for  damages,
specific  performances,  or other  remedies,  the  Sellers  shall be entitled to
reimbursement by Purchaser of reasonable legal fees and expenses incurred by the
Sellers.

         9.2 Break-up Fee. In the event Sellers shall accept a Higher and Better
offer and this Agreement shall terminate in accordance with Section 8(c) hereof,
within five business days of such event Sellers shall pay or cause to be paid to
the Purchaser a Break-up Fee in the amount of $3,000,000 ("Break-up Fee").

         9.3 Expense Reimbursement. In the event this Agreement is terminated by
Purchaser in accordance  with Section 8(e) hereof,  within five business days of
such  event  Sellers  shall  pay or  cause to be paid to the  Purchaser  expense
reimbursement in the amount of $1,000,000 ("Expense Reimbursement").

         9.4 Upset Price. This Agreement is subject to the receipt by Sellers of
a "higher and better"  offer to purchase the Business in an amount not less than
$7,000,000 more than the Purchase Price ("Upset  Price").  Thereafter,  all bids
above the Upset Price shall be in increments of  $2,500,000.  In addition,  as a
condition to Sellers' acceptance of such Higher and Better offer, at the time of
making such offer, the offeror of such Higher and Better offer  ("Offeror") must
present a certified check or official bank check equivalent in the amount of 10%
of its  proposed  purchase  price to serve as a good faith  deposit  against the
Offeror's  purchase  price  ("Higher  and Better"  offer).  Notwithstanding  the
foregoing,  Sellers must offer Purchaser the right,  exercisable for a period of
four hours,  to acquire the Purchased  Assets at the Offeror's  price,  upon the
terms and conditions set forth herein, except that the Purchaser shall receive a
credit  from  Sellers  toward the  Purchase  Price in the  amount of  $3,000,000
("Right  of First  Refusal").  In the  event  Purchaser  exercises  its right to
acquire the Purchased  Assets after a Higher and Better offer, the amount of the
Purchase Price in excess of $100,000,000 shall be paid in the same manner and on
the same terms as specified in Section 3.1 (i.e., (i) 80% in cash on the Closing
Date and (ii) 20% in cash or WCI Shares on the Plan Effective  Date; with 1/5 of
such 20% being deposited into escrow under the Escrow Agreement).

                       ARTICLE X. MISCELLANEOUS PROVISIONS

                                   ARTICLE II.

                                   The Credits

         SECTION  2.01.  Commitments.  Subject to the terms and  conditions  and
relying upon the  representations  and warranties  herein set forth, each Lender
agrees,  severally  and not jointly,  to make a Term Loan to the Borrower on the
Closing  Date in a  principal  amount  not to exceed  its Term Loan  Commitment.
Amounts paid or prepaid in respect of the Term Loan may not be reborrowed.

         SECTION 2.02.  Loans.  (a)  The  Term  Loan  must be drawn in a single
drawing in its entire principal amount on the Closing Date..

         (b) Subject to Sections 2.08 and 2.15, the Term Loan shall initially be
comprised  entirely of ABR Loans or Eurodollar Loans as the Borrower may request
pursuant to Section 2.03. Each Lender may at its option make any Eurodollar Loan
by causing any  domestic or foreign  branch or  Affiliate of such Lender to make
such  Loan;  provided  that any  exercise  of such  option  shall not affect the
obligation  of the Borrower to repay such Loan in  accordance  with the terms of
this Agreement.  Borrowings of more than one Type may be outstanding at the same
time; provided,  however, that the Borrower shall not be entitled to request any
Borrowing that, if made,  would result in more than four  Eurodollar  Borrowings
outstanding  hereunder at any time.  For purposes of the  foregoing,  Borrowings
having different  Interest  Periods,  regardless of whether they commence on the
same date, shall be considered separate Borrowings.

         (c) Each Lender shall make its  proportion  of the Term Loan to be made
by it hereunder on the Closing Date by wire  transfer of  immediately  available
funds to such  account  in New York City or  another  location  agreed to by the
Borrower and the Administrative  Agent as the Administrative Agent may designate
not later than 11:00  a.m.,  New York City time,  and the  Administrative  Agent
shall by 12:00 (noon),  New York City time, credit the amounts so received to an
account in the name of the Borrower,  maintained with the  Administrative  Agent
and  designated  by the Borrower in the  applicable  Borrowing  Request or, if a
Borrowing  shall not occur on such date because any condition  precedent  herein
specified  shall  not have been met,  return  the  amounts  so  received  to the
respective Lenders.

         (d) Unless the  Administrative  Agent shall have received notice from a
Lender  prior to the date of the Term  Borrowing  that such Lender will not make
available to the  Administrative  Agent such Lender's portion of such Borrowing,
the  Administrative  Agent may assume  that such  Lender  has made such  portion
available  to the  Administrative  Agent  on  the  date  of  such  Borrowing  in
accordance  with  paragraph  (c)  above and the  Administrative  Agent  may,  in
reliance  upon such  assumption,  make  available to the Borrower on such date a
corresponding  amount.  If the  Administrative  Agent  shall  have so made funds
available  then, to the extent that such Lender shall not have made such portion
available to the  Administrative  Agent, such Lender and the Borrower  severally
agree  to  repay  to  the   Administrative   Agent   forthwith  on  demand  such
corresponding  amount together with interest thereon, for each day from the date
such  amount is made  available  to the  Borrower  until the date such amount is
repaid  to the  Administrative  Agent  at (i) in the case of the  Borrower,  the
interest rate applicable at the time to the Loans  comprising such Borrowing and
(ii) in the case of such Lender, a rate determined by the  Administrative  Agent
to  represent  its cost of overnight or  short-term  funds (which  determination
shall be conclusive absent manifest error).

If such  Lender  shall  repay to the  Administrative  Agent  such  corresponding
amount,  such  amount  shall  constitute  such  Lender's  Loan  as  part of such
Borrowing for purposes of this Agreement.

         (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be  entitled  to  request,  or to elect to  convert or  continue,  any
Borrowing if the Interest Period  requested with respect thereto would end after
the Term Loan Maturity Date.

         SECTION  2.03.  Borrowing  Procedure.  In  order  to  effect  the  Term
Borrowing,  the Borrower  shall hand  deliver or telecopy to the  Administrative
Agent or give the  Administrative  Agent  telephonic  notice (followed by a hard
copy delivered by first class mail) of a duly completed Borrowing Request (a) in
the case of a  Eurodollar  Borrowing,  not later than 11:00 a.m.,  New York City
time, three Business Days before the Closing Date, and (b) in the case of an ABR
Borrowing,  not later than 11:00 a.m.,  New York City time, on the Closing Date.
The Borrowing  Request shall be irrevocable,  shall be signed by or on behalf of
the  Borrower  and shall  specify  the  following  information:  (i) whether the
Borrowing  then  being  requested  is to be a  Eurodollar  Borrowing  or an  ABR
Borrowing;  (ii) the date of such  Borrowing  (which shall be the Closing Date),
(iii) the number and  location of the account to which funds are to be disbursed
(which  shall be an  account  that  complies  with the  requirements  of Section
2.02(c)); (iv) the amount of such Borrowing;  and (v) if such Borrowing is to be
a Eurodollar  Borrowing,  the Interest  Period with respect  thereto;  provided,
however,  that,  notwithstanding  any contrary  specification  in any  Borrowing
Request, the requested Borrowing shall comply with the requirements set forth in
Section  2.02.  If no election as to the Type of  Borrowing  is specified in any
such notice,  then the  requested  Borrowing  shall be an ABR  Borrowing.  If no
Interest  Period with  respect to any  Eurodollar  Borrowing is specified in any
such  notice,  then the  Borrower  shall be deemed to have  selected an Interest
Period of one month's duration.  The Administrative  Agent shall promptly advise
the  applicable  Lenders of any notice given  pursuant to this Section 2.03 (and
the contents thereof), and of each Lender's portion of the requested Borrowing.

         SECTION 2.04. Evidence  of  Debt;  Repayment of Loans. (a) The Borrower
hereby unconditionally  promises  to  pay to the  Administrative  Agent for the
account of each Lender the principal amount of its proportion of  the Term Loans
as provided in Section 2.11.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts  evidencing the  indebtedness of the Borrower to such Lender
resulting  from each Loan made by such Lender from time to time,  including  the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

         (c) The  Administrative  Agent shall maintain accounts in which it will
record  (i) the amount of each Loan made  hereunder,  the Type  thereof  and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and  payable or to become due and payable  from the  Borrower to each Lender
hereunder and (iii) the amount of any sum received by the  Administrative  Agent
hereunder from the Borrower or the Guarantor and each Lender's share thereof.

         (d) The entries made in the accounts  maintained pursuant to paragraphs
(b) and (c) above shall be prima facie  evidence of the existence and amounts of
the obligations  therein recorded;  provided,  however,  that the failure of any
Lender or the Administrative Agent to maintain such

                                                                             24

accounts or any error therein shall not in any manner affect the  obligations of
the Borrower to repay the Loans in accordance with their terms.

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall  request and receive a  promissory  note payable to such Lender
and its registered assigns, the interests  represented by such note shall at all
times (including after any assignment of all or part of such interests  pursuant
to Section 10.04) be represented by one or more promissory  notes payable to the
payee named therein or its registered assigns.

         SECTION 2.05.  Fees. (a) The Borrower  agrees to pay the Fees set forth
in the Fee Letter at the times and in the amounts  specified  therein.  All Fees
shall  be  paid  on the  dates  due,  in  immediately  available  funds,  to the
Administrative Agent for distribution, if and as appropriate, among the Lenders.
Once paid, none of the Fees shall be refundable under any circumstances.

         SECTION  2.06.  Interest  on Loans.  (a) Subject to the  provisions  of
Section  2.07,  the Loans  comprising  each ABR  Borrowing  shall bear  interest
(computed  on the basis of the actual  number of days elapsed over a year of 365
or 366 days, as the case may be, when the  Alternate  Base Rate is determined by
reference to the Prime Rate and over a year of 360 days at all other times) at a
rate per annum equal to the Alternate Base Rate plus 2.00%.

         (b) Subject to the  provisions  of Section 2.07,  the Loans  comprising
each  Eurodollar  Borrowing  shall bear  interest  (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to the Adjusted LIBO Rate for the Interest  Period in effect for such  Borrowing
plus 3.50%.

         Interest on each Loan shall be payable on the  Interest  Payment  Dates
applicable  to such Loan except as  otherwise  provided in this  Agreement.  The
applicable Alternate Base Rate or Adjusted LIBO Rate for each Interest Period or
day within an Interest  Period,  as the case may be, shall be  determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

         SECTION 2.07.  Default  Interest.  If (a) the Borrower shall default in
the payment of the  principal  of or  interest  on any Loan or any other  amount
becoming due hereunder,  by acceleration  or otherwise,  or under any other Loan
Document,  or (b) upon the  occurrence  and  continuance  of an Event of Default
specified  in clauses (d),  (e),  (g) or (h) of Article VII, the Borrower  shall
upon the demand of the Required  Lenders from time to time pay interest,  to the
extent permitted by law, on all amounts  outstanding  hereunder on but excluding
the date of actual payment  (after as well as before  judgment) or the date that
such Event of Default is otherwise  cured (a) in the case of principal  amounts,
at the rate  otherwise  applicable  to such Loan  pursuant to Section  2.06 plus
2.00% per annum and (b) in all other cases, at a rate per annum (computed on the
basis of the actual  number of days elapsed  over a year of 365 or 366 days,  as
the case may be, when  determined by reference to the Prime Rate and over a year
of 360 days at all other times) equal to the sum of the Alternate Base Rate plus
2.00%.

     SECTION  2.08.  Alternate  Rate  of  Interest.  In the  event,  and on each
occasion,  that on the day two Business  Days prior to the  commencement  of any
Interest Period for a Eurodollar  Borrowing the Administrative  Agent shall have
determined that dollar deposits in the principal


<PAGE>


                                                                           25

amounts of the Loans  comprising  such Borrowing are not generally  available in
the London interbank market, or that the rates at which such dollar deposits are
being  offered will not  adequately  and fairly  reflect the cost to the Lenders
holding at least 51% of such Loans,  of making or maintaining  their  Eurodollar
Loan during such  Interest  Period,  or that  reasonable  means do not exist for
ascertaining the Adjusted LIBO Rate, the Administrative  Agent shall, as soon as
practicable  thereafter,  give hand delivered written or telecopy notice of such
determination  to the  Borrower  and  the  Lenders.  In the  event  of any  such
determination,  until the  Administrative  Agent shall have advised the Borrower
and the  Lenders  that the  circumstances  giving  rise to such notice no longer
exist,  any  request by the  Borrower  for a  Eurodollar  Borrowing  pursuant to
Section 2.03 or 2.10 shall be deemed to be a request for an ABR Borrowing.  Each
determination by the  Administrative  Agent hereunder shall be conclusive absent
manifest error.

         SECTION 2.09.  Termination  and  Reduction  of  Commitments.   The Term
Loan Commitments shall automatically terminate at 5:00 p.m., New York City time,
on the Closing Date.


         SECTION 2.10.  Conversion and Continuation of Borrowings.  The Borrower
shall  have  the  right  at  any  time  upon  prior  irrevocable  notice  to the
Administrative  Agent (a) not later than 12:00 (noon),  New York City time,  one
Business Day prior to conversion,  to convert any  Eurodollar  Borrowing into an
ABR Borrowing, (b) not later than 11:00 a.m., New York City time, three Business
Days prior to conversion or  continuation,  to convert any ABR Borrowing  into a
Eurodollar  Borrowing  or to continue any  Eurodollar  Borrowing as a Eurodollar
Borrowing for an additional  Interest Period, and (c) not later than 11:00 a.m.,
New York City time,  three  Business  Days prior to  conversion,  to convert the
Interest Period with respect to any Eurodollar  Borrowing to another permissible
Interest Period, subject in each case to the following:

                   (i) each  conversion or  continuation  shall be made pro rata
         among the Lenders in accordance with the respective  principal  amounts
         of the Loans comprising the converted or continued Borrowing;  provided
         that each Borrowing shall be in a principal  amount that is an integral
         multiple of $100,000;

                  (ii) if less than all the outstanding  principal amount of any
         Borrowing  shall  be  converted  or  continued,   then  each  resulting
         Borrowing shall satisfy the limitations  specified in Sections  2.02(a)
         and  2.02(b)  regarding  the  principal  amount and  maximum  number of
         Borrowings of the relevant Type;

                  (iii) each conversion shall be effected by each Lender and the
         Administrative  Agent by  recording  for the account of such Lender the
         new Loan of such Lender resulting from such conversion and reducing the
         Loan  (or  portion  thereof)  of  such  Lender  being  converted  by an
         equivalent  principal  amount;  accrued interest on any Eurodollar Loan
         (or portion  thereof) being  converted shall be paid by the Borrower at
         the time of conversion;

                  (iv) if any Eurodollar  Borrowing is converted at a time other
         than the end of the Interest Period  applicable  thereto,  the Borrower
         shall pay,  upon  demand,  any amounts  due to the Lenders  pursuant to
         Section 2.16;


<PAGE>


                                                                            26

                  (v) any  portion of a  Borrowing  maturing  or  required to be
         repaid in less than one month may not be converted into or continued as
         a Eurodollar Borrowing;

                  (vi) any  portion of a  Eurodollar  Borrowing  that  cannot be
         converted into or contin ued as a Eurodollar Borrowing by reason of the
         immediately  preceding clause shall be  automatically  converted at the
         end of the  Interest  Period in effect for such  Borrowing  into an ABR
         Borrowing;

                  (vii) no Interest  Period may be selected  for any  Eurodollar
         Borrowing that would end later than the Term Loan Maturity Date; and

                  (viii) upon  notice to the  Borrower  from the  Administrative
         Agent  given  at  the  request  of  the  Required  Lenders,  after  the
         occurrence and during the continuance of a Default or Event of Default,
         no  outstanding  Loan may be converted  into,  or  continued  after the
         then-current Interest Period as, a Eurodollar Loan.

         Each notice  pursuant to this  Section  2.10 shall be  irrevocable  and
shall refer to this  Agreement  and specify (w) the  identity  and amount of the
Borrowing that the Borrower requests be converted or continued, (x) whether such
Borrowing is to be converted to or continued as a Eurodollar Borrowing or an ABR
Borrowing, (y) if such notice requests a conversion, the date of such conversion
(which shall be a Business Day) and (z) if such  Borrowing is to be converted to
or  continued  as a  Eurodollar  Borrowing,  the  Interest  Period with  respect
thereto.  If no Interest  Period is specified in any such notice with respect to
any conversion to or continuation as a Eurodollar Borrowing,  the Borrower shall
be deemed to have  selected an  Interest  Period of one  month's  duration.  The
Administrative  Agent shall advise the Lenders of any notice  given  pursuant to
this Section  2.10 and of each  Lender's  portion of any  converted or continued
Borrowing.  If the Borrower shall not have given notice in accordance  with this
Section 2.10 to continue any Borrowing  into a subsequent  Interest  Period (and
shall not otherwise  have given notice in  accordance  with this Section 2.10 to
convert such Borrowing), such Borrowing shall, at the end of the Interest Period
applicable  thereto (unless repaid pursuant to the terms hereof),  automatically
be continued into a new Interest Period as an ABR Borrowing.

         SECTION 2.11.  Repayment of  Borrowings.  To the extent not  previously
paid,  all  Borrowings  shall be due and payable on the Term Loan Maturity Date.
The payment of the Borrowings pursuant to this Section 2.11 shall be accompanied
by accrued  interest on the  principal  amount paid to but excluding the date of
payment.

         SECTION  2.12.  Optional  Prepayment.  (a) The Borrower  shall have the
right at any time and from time to time to prepay any Borrowing,  in whole or in
part,  upon at least 3  Business  Days  prior  written  or  telecopy  notice (or
telephone  notice  promptly  confirmed  by  written or  telecopy  notice) to the
Administrative Agent before 11:00 a.m., New York City time;  provided,  however,
that each partial  prepayment shall be in an amount that is an integral multiple
of $100,000 and not less than $500,000.

        (b) Each notice of  prepayment  shall specify the  prepayment  date and
the  principal  amount of each  Borrowing (or portion thereof)  to  be prepaid,
shall  be  irrevocable and shall commit the Borrower to prepay such Borrowing by
the amount stated therein on the date stated therein. All

                                                                            27

prepayments  under this  Section  2.12  shall be  subject  to  Section  2.16 but
otherwise  without premium or penalty.  All prepayments  under this Section 2.12
shall be accompanied by accrued  interest on the principal  amount being prepaid
to the date of payment.

         SECTION 2.13. Mandatory Prepayments. (a) In the event of any Asset Sale
with respect to the Collateral, the Borrower shall apply an amount equal to 100%
of the Net Cash  Proceeds  received with respect  thereto to prepay  outstanding
Loans on the date of such Asset Sale.

         (b) In the event and on each  occasion  that WCI,  the  Borrower or any
Restricted  Subsidiary  shall receive Net Cash Proceeds from an Equity Issuance,
the  Borrower  shall,  substantially  simultaneously  with (and in any event not
later than the third Business Day next  following) the occurrence of such Equity
Issuance,  apply an amount equal to the lesser of 100% of the Net Cash  Proceeds
therefrom on the amount then  outstanding  under the Loans to prepay or cause to
be prepaid outstanding Loans.

         (c) In the event that WCI,  the Borrower or any  Restricted  Subsidiary
shall receive Net Cash Proceeds from the issuance of any Indebtedness other than
Excluded  Indebtedness,  the Borrower shall,  substantially  simultaneously with
(and in any event not later  than the third  Business  Day next  following)  the
receipt  of such Net Cash  Proceeds  by WCI,  the  Borrower  or such  Restricted
Subsidiary,  apply  an  amount  equal  to the  lesser  of 100% of such  Net Cash
Proceeds or the amount then outstanding under the Loans to prepay or cause to be
prepaid outstanding Loans.

         (d) The Borrower shall deliver to the Administrative Agent, at the time
of each prepayment required under this Section 2.13, (i) a certificate signed by
a Responsible  Officer of the Borrower  setting  forth in reasonable  detail the
calculation of the amount of such prepayment and (ii) to the extent practicable,
at least three days prior written notice of such prepayment.  Each notice of pre
payment shall specify the  prepayment  date, the Type of each Loan being prepaid
and the principal  amount of each Loan (or portion  thereof) to be prepaid.  All
prepayments  of  Borrowings  under this Section 2.13 shall be subject to Section
2.16, but shall otherwise be without premium or penalty.

         (e)  Amounts  to be  applied  pursuant  to  this  Section  2.13  to the
prepayment of Loans shall be applied first to reduce  outstanding ABR Loans. Any
amounts  remaining after each such application  shall be immediately  applied to
prepay  Eurodollar  Loans. All prepayments of Borrowings under this Section 2.13
shall be accompanied by accrued  interest on the principal  amount being prepaid
to the date of payment.

         SECTION  2.14.  Reserve  Requirements;  Change  in  Circumstances.  (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration   thereof  by  any  Governmental   Authority   charged  with  the
interpretation  or  administration  thereof  (whether or not having the force of
law)  shall  change  the basis of  taxation  of  payments  to any  Lender of the
principal of or interest on any Eurodollar  Loan made by such Lender or any Fees
or other  amounts  payable  hereunder  (other  than  changes in respect of taxes
imposed on the overall net income of such  Lender by the  jurisdiction  in which
such Lender has its principal  office or by any political  subdivision or taxing
authority  therein),  or shall impose,  modify or deem  applicable  any reserve,
special deposit or similar  requirement  against assets of, deposits with or for
the  account  of or credit  extended  by any  Lender  (except  any such  reserve
requirement which is reflected in the Adjusted LIBO Rate) or shall impose


<PAGE>


                                                                           28

on such Lender or the London interbank market any other condition affecting this
Agreement or  Eurodollar  Loans made by such Lender and the result of any of the
foregoing  shall be to increase the cost to such Lender of making or maintaining
any Eurodollar Loan or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise) by an amount
reasonably  deemed by such Lender to be material,  then the Borrower will pay to
such Lender,  upon demand,  such additional amount or amounts as will compensate
such Lender for such additional costs incurred or reduction suffered.

         (b) If any Lender shall have  reasonably  determined  that the adoption
after the date  hereof of any law,  rule,  regulation,  agreement  or  guideline
regarding capital adequacy, or any change after the date hereof in any such law,
rule,  regulation,  agreement or guideline (whether such law, rule,  regulation,
agreement  or  guideline  has  been  adopted)  or  in  the   interpretation   or
administration   thereof  by  any  Governmental   Authority   charged  with  the
interpretation  or administration  thereof,  or compliance by any Lender (or any
lending office of such Lender) or any Lender's  holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any Governmental  Authority has or would have the effect of reducing the rate
of return on such Lender's  capital or on the capital of such  Lender's  holding
company,  if any, as a consequence  of this  Agreement or the Loans made by such
Lender  pursuant hereto to a level below that which such Lender or such Lender's
holding company could have achieved but for such applicability, adoption, change
or compliance (taking into consideration such Lender's policies and the policies
of such  Lender's  holding  company with  respect to capital  adequacy and using
reasonable  allocation  methods)  by an  amount  deemed  by  such  Lender  to be
material,  then from time to time the  Borrower  shall pay to such  Lender  such
additional  amount or amounts as will  compensate  such Lender or such  Lender's
holding company for any such reduction suffered.

         (c) A  certificate  of a Lender  setting  forth the  amount or  amounts
necessary  to  compensate  such Lender or its holding  company as  specified  in
paragraph  (a) or (b) above  shall be  delivered  to the  Borrower  and shall be
conclusive  absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such  certificate  delivered  by it within 10 days after its
receipt of the same.

         (d)  Failure or delay on the part of any Lender to demand  compensation
for any  increased  costs or  reduction  in amounts  received or  receivable  or
reduction in return on capital  shall not  constitute a waiver of such  Lender's
right to demand such compensation;  provided that unless a retroactive change in
the applicable  laws,  rules,  regulations,  agreements or guidelines shall have
occurred,  each Lender  shall  request  such  compensation  within six months of
incurring any such increased costs or reductions. The protection of this Section
shall be available to each Lender  regardless of any possible  contention of the
invalidity or inapplicability of the law, rule, regulation, agreement, guideline
or other change or condition that shall have occurred or been imposed; provided,
however,  if subsequent to the payment of such  compensation  the basis for such
compensation  is  conclusively  determined to be invalid or  inapplicable,  such
compensation will be refunded by such Lender to the Borrower.

         SECTION  2.15.  Change  in  Legality.  (a)  Notwithstanding  any  other
provision of this Agreement, if, after the date hereof, any change in any law or
regulation  or in  the  interpretation  thereof  by any  Governmental  Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to


<PAGE>


                                                                           29

its  obligations as  contemplated  hereby with respect to any  Eurodollar  Loan,
then, by written notice to the Borrower and to the Administrative Agent:

                  (i) such Lender may  declare  that  Eurodollar  Loans will not
         thereafter  (for the  duration  of such  unlawfulness)  be made by such
         Lender  hereunder (or be continued for additional  Interest Periods and
         ABR Loans will not  thereafter  (for such  duration) be converted  into
         Eurodollar Loans), whereupon any request for a Eurodollar Borrowing (or
         to convert an ABR Borrowing to a Eurodollar  Borrowing or to continue a
         Eurodollar  Borrowing for an additional  Interest  Period) shall, as to
         such Lender only,  be deemed a request for an ABR Loan (or a request to
         continue an ABR Loan as such for an  additional  Interest  Period or to
         convert a Eurodollar Loan into an ABR Loan, as the case may be), unless
         such declaration shall be subsequently withdrawn; and

                  (ii) such Lender may require that all  outstanding  Eurodollar
         Loans made by it be  converted  to ABR Loans,  in which  event all such
         Eurodollar  Loans shall be  automatically  converted to ABR Loans as of
         the effective date of such notice as provided in paragraph (b) below.

In the event any Lender shall  exercise its rights under (i) or (ii) above,  all
payments and  prepayments of principal that would otherwise have been applied to
repay the  Eurodollar  Loans  that  would  have been made by such  Lender or the
converted  Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting  from the  conversion of,
such Eurodollar Loans.

         (b) For purposes of this Section  2.15, a notice to the Borrower by any
Lender  shall be effective as to each  Eurodollar  Loan made by such Lender,  if
lawful,  on the last day of the Interest  Period  currently  applicable  to such
Eurodollar  Loan;  in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION  2.16.  Indemnity.  The Borrower  shall  indemnify  each Lender
against  any  loss or  expense  that  such  Lender  may  sustain  or  incur as a
consequence  of (a) any  event,  other  than a  default  by such  Lender  in the
performance  of its  obligations  hereunder,  which  results in (i) such  Lender
receiving or being  deemed to receive any amount on account of the  principal of
any Eurodollar Loan prior to the end of the Interest Period in effect  therefor,
(ii) the conversion of any Eurodollar  Loan to an ABR Loan, or the conversion of
the Interest Period with respect to any Eurodollar Loan, in each case other than
on the last  day of the  Interest  Period  in  effect  therefor,  or  (iii)  any
Eurodollar  Loan to be made by such Lender  (including any Eurodollar Loan to be
made pursuant to a conversion or continuation under Section 2.10) not being made
after notice of such Loan shall have been given by the Borrower  hereunder  (any
of the events referred to in this clause (a) being called a "Breakage Event") or
(b) any default in the making of any payment or  prepayment  required to be made
hereunder.  In the case of any Breakage Event, such loss shall include an amount
equal to the excess, as reasonably determined by such Lender, of (i) its cost of
obtaining  funds for the  Eurodollar  Loan that is the subject of such  Breakage
Event for the period from the date of such Breakage Event to the last day of the
Interest Period in effect (or that would have been in effect) for such Loan over
(ii) the amount of interest  likely to be realized by such Lender in redeploying
the funds  released or not  utilized by reason of such  Breakage  Event for such
period.  A certificate  of any Lender  setting forth any amount or amounts which
such Lender is entitled to

                                                                           30

receive  pursuant to this  Section  2.16 shall be  delivered to the Borrower and
shall be conclusive absent manifest error.

         SECTION  2.17.  Pro Rata  Treatment.  Except as required  under Section
2.15, each Borrowing,  each payment or prepayment of principal of any Borrowing,
each payment of interest on the Loans,  and each  conversion of any Borrowing to
or  continuation  of any Borrowing as a Borrowing of any Type shall be allocated
pro rata among the Lenders in accordance with their respective  principal amount
of the  outstanding  Loans.  Each Lender agrees that in computing  such Lender's
portion of any Borrowing to be made hereunder,  the Administrative Agent may, in
its  discretion,  round each Lender's  percentage of such  Borrowing to the next
higher or lower whole dollar amount.

         SECTION  2.18.  Payments.  (a) The  Borrower  shall  make each  payment
(including  principal  of or  interest  on any  Borrowing  or any  Fees or other
amounts)  hereunder  and under any other  Loan  Document  not later  than  12:00
(noon),  New York  City  time,  on the date  when due in  immediately  available
dollars,  without setoff,  defense or  counterclaim.  Each such payment shall be
made to the Administrative Agent to such accounts in New York City, New York, or
such other place as the  Administrative  Agent may from time to time  reasonably
direct the Borrower.

         (b)  Whenever  any payment  (including  principal of or interest on any
Borrowing  or any Fees or other  amounts)  hereunder  or under  any  other  Loan
Document  shall  become due, or otherwise  would  occur,  on a day that is not a
Business Day, such payment may be made on the next succeeding  Business Day, and
such  extension  of time shall in such case be  included in the  computation  of
interest or Fees, if applicable.

         SECTION  2.19.  Taxes.  (a) Any and all payments by or on behalf of the
Borrower or any Loan Party  hereunder and under any other Loan Document shall be
made, in accordance with Section 2.18,  free and clear of and without  deduction
for any and all current or future taxes, levies, imposts, deductions, charges or
withholdings,  and all  liabilities,  costs and expenses  with respect  thereto,
excluding (i) income taxes imposed on the net income of the Administrative Agent
or any Lender (or any transferee or assignee thereof,  including a participation
holder (any such entity a  "Transferee"))  and (ii)  franchise or similar  taxes
imposed on or  determined  by reference to the net income of the  Administrative
Agent or any  Lender  (or  Transferee),  in each  case by the  United  States of
America or by the jurisdiction under the laws of which the Administrative  Agent
or such Lender (or  Transferee)  (A) is organized or any  political  subdivision
thereof or (B) has its applicable lending office located (in each case, all such
nonexcluded taxes, levies, imposts, deductions,  charges, and withholdings,  and
related  liabilities,  costs and expenses,  collectively or individually,  being
called  "Taxes").  If the Borrower or any Loan Party shall be required to deduct
any Taxes  from or in respect of any sum  payable  hereunder  or under any other
Loan Document to the Administrative Agent or any Lender (or any Transferee), (i)
the sum  payable  shall be  increased  by the  amount (an  "additional  amount")
necessary  so that after making all required  deductions  (including  deductions
applicable   to   additional   sums  payable   under  this  Section   2.19)  the
Administrative  Agent or such Lender (or Transferee),  as the case may be, shall
receive an amount equal to the sum it would have received had no such deductions
been made,  (ii) the Borrower or such Loan Party shall make such  deductions and
(iii) the Borrower or such Loan Party shall pay the full amount  deducted to the
relevant Governmental Authority in accordance with applicable law.

         (b)  In  addition,   the  Borrower   agrees  to  pay  to  the  relevant
Governmental  Authority in accordance  with applicable law any current or future
stamp,  transfer or  documentary  taxes or any other  excise or property  taxes,
charges or similar  levies that arise from any payment  made  hereunder or under
any other Loan Document or from the execution,  delivery or registration  of, or
otherwise  with respect to, this  Agreement or any other Loan  Document  ("Other
Taxes").

         (c) The  Borrower  will  indemnify  the  Administrative  Agent and each
Lender (or  Transferee) for the full amount of Taxes and Other Taxes paid by the
Administrative Agent or such Lender (or Transferee), as the case may be, and any
liability  (including  penalties,  interest and expenses  (including  reasonable
attorney's  fees and  expenses))  arising  therefrom  or with  respect  thereto,
whether or not such Taxes or Other Taxes were  correctly or legally  assessed by
the relevant  Governmental  Authority.  A  certificate  as to the amount of such
payment  or  liability  prepared  by the  Administrative  Agent or a Lender  (or
Transferee),  or the Administrative Agent on its behalf,  absent manifest error,
shall be final,  conclusive and binding for all purposes.  Such  indemnification
shall be made  within  30 days  after the date the  Administrative  Agent or any
Lender (or Transferee),  as the case may be, makes written demand  therefor.  If
any Lender (or  Transferee)  or the  Administrative  Agent  receives a refund in
respect of any Taxes or Other Taxes for which such Lender (or Transferee) or the
Administrative Agent has received payment from the Borrower hereunder,  it shall
promptly  repay such refund  (plus any interest  received) to the Borrower  (but
only to the extent of indemnity  payments  made, or additional  amounts paid, by
the  Borrower  under this  Section 2.19 with respect to the Taxes or Other Taxes
giving rise to such refund);  provided  that the  Borrower,  upon the request of
such Lender (or Transferee) or the Administrative  Agent,  agrees to return such
refund (plus any  penalties,  interest or other charges  required to be paid) to
such  Lender  or the  Administrative  Agent  in the  event  such  Lender  or the
Administrative  Agent is required to repay such  refund to the  relevant  taxing
authority.

         (d) As soon as  practicable  after the date of any  payment of Taxes or
Other Taxes by the Borrower or any other Loan Party to the relevant Governmental
Authority,   the  Borrower  or  such  other  Loan  Party  will  deliver  to  the
Administrative  Agent, at its address referred to in Section 10.01, the original
or  a  certified  copy  of a  receipt  issued  by  such  Governmental  Authority
evidencing payment thereof.

         (e) Each Lender (or  Transferee)  that is organized under the laws of a
jurisdiction  other than the United States, any State thereof or the District of
Columbia  (a  "Non-U.S.   Lender")   shall  deliver  to  the  Borrower  and  the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S.  Lender claiming exemption
from U.S.  Federal  withholding  tax under Section  871(h) or 881(c) of the Code
with respect to payments of "portfolio interest",  a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S.  Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent  shareholder (within
the meaning of Section  871(h)(3)(B)  of the Code) of the  Borrower and is not a
controlled  foreign  corporation  related to the Borrower (within the meaning of
Section  864(d)(4) of the Code)),  properly  completed and duly executed by such
Non-U.S.  Lender  claiming  complete  exemption  from,  or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement and the
other Loan Documents.  Such forms shall be delivered by each Non-U.S.  Lender on
or before the date it becomes a party to this  Agreement  (or,  in the case of a
Transferee  that  is  a  participation  holder,  on  or  before  the  date  such
participation holder becomes a Transferee hereunder)


<PAGE>


                                                                            32

and on or before the date, if any, such Non-U.S.  Lender  changes its applicable
lending  office by  designating  a  different  lending  office  (a "New  Lending
Office"). In addition,  each Non-U.S.  Lender shall upon written notice from the
Borrower  promptly  deliver  such new forms as are  required  by the Code or the
regulations  issued thereunder to claim exemption from, or reduction in the rate
of, U.S. Federal withholding tax upon the obsolescence or invalidity of any form
previously  delivered  by  such  Non-U.S.  Lender.   Notwithstanding  any  other
provision of this Section  2.19(e),  a Non-U.S.  Lender shall not be required to
deliver any form pursuant to this Section 2.19(e) that such Non-U.S.
Lender is not legally able to deliver.

         (f) The Borrower shall not be required to indemnify any Non-U.S. Lender
or to pay any additional  amounts to any Non-U.S.  Lender,  in respect of United
States  Federal  withholding  tax pursuant to paragraph  (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax was applicable on the date such Non-U.S. Lender became a
party to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Lending Office, the date such Non-U.S.  Lender
designated  such New Lending Office with respect to a Loan;  provided,  however,
that this  paragraph  (f) shall not apply (x) to any  Transferee  or New Lending
Office  that  becomes  a  Transferee  or New  Lending  Office  as a result of an
assignment,  participation,  transfer or designation  made at the request of the
Borrower and (y) to the extent the indemnity  payment or additional  amounts any
Transferee, or any Lender (or Transferee),  acting through a New Lending Office,
would be  entitled  to receive  (without  regard to this  paragraph  (f)) do not
exceed the indemnity  payment or  additional  amounts that the person making the
assignment,  participation  or  transfer  to  such  Transferee,  or  Lender  (or
Transferee)  making the designation of such New Lending Office,  would have been
entitled to receive in the absence of such assignment,  participation,  transfer
or designation or (ii) the obligation to pay such  additional  amounts would not
have  arisen  but for a failure  by such  Non-U.S.  Lender  to  comply  with the
provisions of paragraph (e) above.

         (g) Nothing contained in this Section 2.19 shall require any Lender (or
any  Transferee)  or the  Administrative  Agent to make available any of its tax
returns (or any other information that it deems in its reasonable  discretion to
be confidential or proprietary).

         SECTION 2.20. Assignment of Interests Under Certain Circumstances; Duty
to Mitigate.  (a) In the event (i) any Lender delivers a certificate  requesting
compensation  pursuant  to  Section  2.14,  (ii) any  Lender  delivers  a notice
described  in  Section  2.15  or  (iii)  the  Borrower  is  required  to pay any
additional amount to any Lender or any Governmental  Authority on account of any
Lender  pursuant to Section  2.19,  the  Borrower  may, at its sole  expense and
effort (including with respect to the processing and recordation fee referred to
in Section 10.04(b)),  upon notice to such Lender and the Administrative  Agent,
require such Lender to transfer and assign, without recourse (in accordance with
and  subject  to  the  restrictions  contained  in  Section  10.04),  all of its
interests, rights and obligations under this Agreement to an assignee that shall
assume such assigned  obligations  (which assignee may be another  Lender,  if a
Lender accepts such  assignment);  provided that (x) such  assignment  shall not
conflict  with  any law,  rule or  regulation  or  order  of any  court or other
Governmental Authority having jurisdiction, (y) the Borrower shall have received
the prior written consent of the  Administrative  Agent, which consent shall not
unreasonably be withheld,  and (z) the Borrower or such assignee shall have paid
to the affected Lender in immediately available funds an amount equal to the sum
of the principal of and interest accrued to the date of such payment


<PAGE>


                                                                             33

on the outstanding  Loans of such Lender plus all Fees and other amounts accrued
for the account of such Lender  hereunder  (including  any amounts under Section
2.14 and Section 2.16); provided further that, if prior to any such transfer and
assignment the  circumstances  or event that resulted in such Lender's claim for
compensation under Section 2.14 or notice under Section 2.15 or the amounts paid
pursuant  to Section  2.19,  as the case may be,  cease to cause such  Lender to
suffer  increased  costs or  reductions  in amounts  received or  receivable  or
reduction in return on capital,  or cease to have the consequences  specified in
Section 2.15, or cease to result in amounts being payable under Section 2.19, as
the case  may be  (including  as a result  of any  action  taken by such  Lender
pursuant to  paragraph  (b) below),  or if such Lender  shall waive its right to
claim further  compensation  under Section 2.14 in respect of such circumstances
or event or shall  withdraw  its notice  under  Section  2.15 or shall waive its
right to further payments under Section 2.19 in respect of such circumstances or
event,  as the case may be, then such Lender shall not thereafter be required to
make any such transfer and assignment hereunder.

         (b) If (i) any Lender shall  request  compensation  under Section 2.14,
(ii) any  Lender  delivers  a notice  described  in  Section  2.15 or (iii)  the
Borrower  is  required  to  pay  any  additional  amount  to any  Lender  or any
Governmental Authority on account of any Lender,  pursuant to Section 2.19, then
such Lender shall use reasonable efforts (which shall not require such Lender to
incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any
action  inconsistent  with  legal  or  regulatory  restrictions  or  suffer  any
disadvantage  or  burden  deemed  by it to  be  significant)  (x)  to  file  any
certificate or document  reasonably  requested in writing by the Borrower or (y)
to assign its rights and  delegate and  transfer  its  obligations  hereunder to
another of its offices,  branches or  affiliates,  if such filing or  assignment
would  reduce its claims for  compensation  under  Section  2.14 or enable it to
withdraw its notice  pursuant to Section 2.15 or would  reduce  amounts  payable
pursuant to Section 2.19, as the case may be, in the future. The Borrower hereby
agrees  to pay all  reasonable  costs and  expenses  incurred  by any  Lender in
connection with any such filing or assignment, delegation and transfer.


                                  ARTICLE III.

                         Representations and Warranties

been duly incorporated and is an existing corporation in good standing under the
laws of the State of Delaware,  with  corporate  power and  authority to own its

Document or the SEC Filings;  and each of the Borrower and WCI is duly qualified
to  do  business  as a  foreign  corporation  in  good  standing  in  all  other
jurisdictions in which its owner ship or lease of property or the conduct of its
business requires such  qualification,  except to the extent that the failure to
be so qualified or be in good standing would not have a material  adverse effect
on the  condition  (financial  or  other),  business,  properties  or results of
operations  of each of the Borrower and WCI and their  respective  Subsidiaries,
taken as a whole (a "Material Adverse Effect").  Each of the Borrower and WCI is

                                                                           34

Filings;  and each Subsidiary of the Borrower and each Subsidiary of WCI is duly
qualified to do business as a foreign  corporation in good standing in all other
jurisdictions  in which its ownership or lease of property or the conduct of its
business requires such  qualification,  except to the extent that the failure to
be so qualified or be in good standing would not have a Material Adverse Effect;
all of the  issued  and  outstanding  capital  stock of each  Subsidiary  of the
Borrower and each  Subsidiary of WCI has been duly authorized and validly issued
and is fully paid and  nonassessable;  and the capital stock of each  Subsidiary
owned by the  Borrower  and each  Subsidiary  of WCI,  is owned free from liens,
encumbrances and defects.


         SECTION 3.03. Authorization. The execution, delivery and performance by
each  Loan  Party of each of the  Loan  Documents  to  which it is a party,  the
Borrowings  hereunder and the other  Transactions  and compliance with the terms
and provisions  thereof (a) have been duly authorized and (b) will not result in
a breach or violation  of any of the terms and  provisions  of, or  constitute a
default under,  (i) any statute,  rule,  regulation or order of any governmental
agency or body or any court,  domestic or foreign,  having jurisdiction over the
Borrower,  WCI  or  any  Subsidiary  of the  Borrower  or  WCI  or any of  their
properties,  (ii) any agreement or instrument to which the Borrower,  WCI or any
such Subsidiary is a party or by which the Borrower,  WCI or any such Subsidiary
is bound or to which  any of the  properties  of the  Borrower,  WCI or any such
Subsidiary is subject,  or (iii) the charter or by-laws of the Borrower,  WCI or
any such Subsidiary,  except,  in the case of clause (i) or (ii), such breaches,
violations or defaults that  individually  or in the aggregate  would not have a
Material Adverse Effect.

         SECTION 3.04. Enforceability. This Agreement has been duly executed and
delivered by each Loan Party and constitutes,  and each other Loan Document when
executed and  delivered by each Loan Party  thereto  will  constitute,  a legal,
valid and binding  obligation of such Loan Party  enforceable  against such Loan
Party  in  accordance  with  its  terms,  subject  to  bankruptcy,   insolvency,
fraudulent  transfer,  reorganization,  moratorium  and similar  laws of general
applicability  relating to or affecting  creditors' rights and to general equity
principles.

         SECTION 3.05.  Governmental  Approvals.  No action, consent or approval
of,  registration  or  filing  with  or any  other  action  by any  Governmental
Authority is or will be required in connection with the Transactions, except for

have been made or obtained and are in full force and effect.

         SECTION  3.06.  Financial  Statements.  (a)  The  financial  statements
included or  incorporated  by reference in the SEC Filings present fairly in all
material   respects  the  financial   position  of  WCI  and  its   consolidated
Subsidiaries  as of the dates  shown and their  results of  operations  and cash
flows for the periods shown, and such financial statements have been prepared in
conformity with generally  accepted  accounting  principles in the United States
applied on a consistent  basis;  and the  assumptions  used in preparing the pro
forma  financial  statements  included or  incorporated  by reference in the SEC
Filings  provide a  reasonable  basis for  presenting  the  significant  effects
directly  attributable to the  transactions  or events  described  therein,  the




<PAGE>


                                                                           35

related pro forma  adjustments give  appropriate  effect to those  assumptions,
and the pro forma  columns  therein  reflect  the  proper  application of those
adjustments to the corresponding historical financial statement amounts.

         (b) Except as  disclosed  in the October  Offering  Document or the SEC
Filings,  since the date of the latest audited financial  statements included in
the SEC Filings,  there has been no material adverse change, nor any development
or event  involving a  prospective  material  adverse  change,  in the condition
(financial or other),  business,  properties or results of operations of each of
the  Borrower  and WCI and their  respective  Subsidiaries  taken as a whole (it
being  understood  that a change in WCI's  stock  price or the  continuation  of
operating losses consistent with WCI's historical results shall be deemed not to
be, in and of itself, such a material adverse change),  and, except as disclosed
in or contemplated by the October  Offering  Document or the SEC Filings,  there
has been no dividend or distribution  of any kind declared,  paid or made by the
Borrower or WCI on any class of their capital stock.

         SECTION  3.07.  Title to  Properties.  (a) Except as  disclosed  in the
October  Offering  Document  or the SEC  Filings,  the  Borrower,  WCI and their
respective  Subsidiaries  have good and marketable  title to all real properties
(if any) and all other  properties  and assets owned by them,  in each case free
from liens,  encumbrances  and defects  that would  materially  affect the value
thereof or materially interfere with the use made or to be made thereof by them;
and except as disclosed in the October Offering Document or the SEC Filings, the
Borrower,  WCI and their  Subsidiaries hold any leased real or personal property
under valid and  enforceable  leases with no  exceptions  that would  materially
interfere with the use made or to be made thereof by them.

         SECTION 3.08. Litigation; Compliance with Laws. (a) Except as disclosed
in the  October  Offering  Document  or the SEC  Filings,  there are no  pending
actions,  suits or  proceedings  against or affecting the Borrower,  WCI, any of
their  respective  Subsidiaries  or any of  their  respective  properties  that,
individually  or in the  aggregate,  could  reasonably  be  expected  to  have a
Material  Adverse Effect,  or to materially and adversely  affect the ability of
either of the Borrower or WCI to perform its obligations under this Agreement or
any other Loan Document,  or which are otherwise  material in the context of the
borrowings  hereunder;  and  to  the  best  of the  Borrower's  and  Guarantor's
knowledge, no such actions, suits or proceedings are threatened or contemplated.

         (b) None of the Borrower,  WCI or any of their respective  Subsidiaries
or any of their respective material properties or assets is in violation of, nor
will the  continued  operation  of  their  material  properties  and  assets  as
currently conducted violate, any law, rule or regulation,  or is in default with
respect to any judgment,  writ, injunction,  decree or order of any Governmental
Authority,  where  any  such  violations  or  defaults,  individually  or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect.

         SECTION 3.09.  Agreements.  Neither the Borrower,  WCI nor any of their
respective  Subsidiaries  is in default in any manner under any provision of any
indenture or other agreement or instrument evidencing Indebtedness, or any other
agreement  or  instrument  to  which  it is a party or by which it or any of its
properties or assets is or may be bound,  where any such defaults,  individually
or in the  aggregate,  could  reasonably  be  expected  to result in a  Material
Adverse Effect.

                                                                            36

        SECTION 3.10. Federal  Reserve  Regulations.  (a)  Neither the Borrower,
WCI  nor  any of their respective  Subsidiaries is engaged  principally,  or as
one of its  important  activities,  in  the business of extending credit for the
purpose of buying or carrying Margin Stock.

         (b) No part of the proceeds of any Loan will be used,  whether directly
or indirectly, and whether immediately,  incidentally or ultimately, to purchase
or carry Margin Stock or for any purpose that entails a violation of, or that is
inconsistent  with,  the provisions of the  Regulations of the Board,  including
Regulation G, T, U or X.

         SECTION 3.11.  Investment  Company Act. Neither the Borrower nor WCI is
an open-end investment company, unit investment trust or face-amount certificate
company that is or is required to be  registered  under  Section 8 of the United
States  Investment  Company Act of 1940 (the "Investment  Company Act"), nor are
either of them a closed-end  investment  company required to be registered,  but
not registered, thereunder.

         SECTION  3.12.  Use of Proceeds.  The Borrower will use the proceeds of
the Loans only for the purposes  specified in the preamble to this Agreement and
such uses are specifically  permitted by the October 1997 Notes  Indenture,  the
August 1997 Notes  Indenture,  the indentures each dated as of March 1, 1997, in
respect of the March 1997 Equipment  Notes and the March 1997 Senior Notes,  the
indenture dated as of October 23, 1995,  between WCI and the United States Trust
Company of New York,  as trustee,  in respect of WCI's  $150,000,577  14% Senior
Discount Notes due 2005 and the Convertible Notes Indenture.

         SECTION  3.13.  Tax  Matters.  Each  of the  Borrower,  WCI  and  their
respective  Subsidiaries  has filed or caused  to be filed all  Federal,  state,
local and foreign tax and information returns or materials required to have been
filed by it and has paid or caused to be paid all  taxes due and  payable  by it
and all  assessments  received by it,  except taxes that are being  contested in
good faith by appropriate  proceedings  and for which the Borrower,  WCI or such
Subsidiary, as applicable,  shall have set aside on its books adequate reserves,
and except where the failure to make such filing or payment could not reasonably
be expected to result in a Material Adverse Effect.

         SECTION  3.14. No Material  Misstatements.  WCI's Annual Report on Form
10-K most recently filed with the SEC and all subsequent reports  (collectively,
the "Exchange Act Reports") which have been filed by WCI with the SEC or sent to
stockholders  pursuant to the Exchange  Act,  when they were filed with the SEC,
conformed in all material  respects to the  requirements of the Exchange Act and
the rules and  regulations of the SEC thereunder.  Each of (i) the  registration

the  Securities  Act  (Registration  No.  333-35961)  filed  by WCI and  WinStar

         SECTION  3.16.  Environmental  Matters.  (a) The  properties  owned  or
operated  by  the  Borrower,   WCI  and  their  respective   Subsidiaries   (the

concentrations which (i) constitute a violation of, (ii) require Remedial Action
under, or (iii) could give rise to liability  under,  Environmental  Laws, which
violations, Remedial Actions and liabilities, in the aggregate, could reasonably
be expected to result in a Material Adverse Effect.

         (b) The Properties  and all  operations of the Borrower,  WCI and their
respective Subsidiaries are in compliance, and in the last three years have been
in  compliance,  with all  Environmental  Laws and all  necessary  Environmental

non-compliance  or failure to obtain any necessary  permits,  in the  aggregate,
would not have a Material Adverse Effect.

         (c) There have been no Releases or threatened  Releases at, from, under
or proximate to the Properties or otherwise in connection with the operations of
the Borrower, WCI or their respective Subsidiaries, which Releases or threatened
Releases, in the aggregate, could reasonably be expected to result in a Material
Adverse Effect.

matters the  Borrower,  WCI or their  respective  Subsidiaries  has  retained or
assumed, in whole or in part,  contractually,  by operation of law or otherwise,

reason to believe that any such notice will be received or is being threatened.

         (e) Hazardous  Materials have not been transported from the Properties,
nor have Hazardous Materials been generated,  treated, stored or disposed of at,
on or under any of the  Properties in a manner that could give rise to liability
under any  Environmental  Law, nor have the  Borrower,  WCI or their  respective
Subsidiaries retained or assumed any liability,  contractually,  by operation of
law or otherwise, with respect to the generation, treatment, storage or disposal
of Hazardous Materials,

         SECTION 3.17. Insurance.  Schedule 3.17 sets forth a true, complete and
correct description of all insurance  maintained by the Borrower or by WCI as of
the date hereof and the Closing Date. As of each such date, such insurance is in

to create in favor of the  Administrative  Agent, for the ratable benefit of the
Secured  Parties,  a legal,  valid  and  enforceable  security  interest  in the
Collateral (as defined in the Security Agreement) and, when financing statements
in  appropriate  form are filed in the  offices  specified  on Schedule 4 to the
Perfection  Certificate,   the  Security  Agreement  shall  constitute  a  fully
perfected  Lien on, and security  interest in, all right,  title and interest of

         SECTION  3.19.  Labor  Matters.  As of the date  hereof and the Closing
Date, no labor  dispute with the employees of the Borrower,  WCI or any of their
respective  Subsidiaries  exists or, to the best of knowledge of the Borrower or
WCI, is imminent that could  reasonably  be expected to have a Material  Adverse
Effect.

         SECTION 3.20. Copyrights,  Trademarks, etc. The Borrower, WCI and their
respective  Subsidiaries  own,  possess  or can  acquire  on  reasonable  terms,
adequate  trademarks,  trade  names and other  rights to  inventions,  know-how,
patents,  copyrights,  confidential  information and other intellectual property
(collectively, "intellectual property rights") necessary to conduct the business
as now operated by them,  or used in the conduct of the business as now operated
by  them,  except  to the  extent  that the  failure  to own or  possess  or the
inability to acquire such intellectual property rights would not individually or
in the aggregate have a Material  Adverse Effect;  and the Borrower and WCI have
not received any notice of  infringement  of or conflict with asserted rights of
others with respect to any  intellectual  property  rights that,  if  determined
adversely to the Borrower,  WCI or any of their respective  Subsidiaries,  would
individually or in the aggregate have a Material Adverse Effect.

         SECTION  3.21.  Telecommunications  Act.  The  Borrower,  WCI and their
respective  Subsidiaries  are in  compliance  in all material  respects with the
Communications  Act of 1934,  as amended by the  Telecommunications  Act of 1996
(the  "Communications  Act")  and with all  applicable  rules,  regulations  and
policies of the Federal Communications Commission (the "FCC").

         (b) The Borrower, WCI and their respective Subsidiaries have duly filed
in a timely  manner all  material  filings,  reports,  applications,  documents,
instruments   and   information   required   to  be  filed  by  them  under  the
Communications  Act, and all such filings are true,  correct and complete in all
material respects.

         SECTION 3.22  Licenses.  (a) The Borrower and WCI have  provided to the
Purchasers a complete and accurate list of all licenses granted to the Borrower,
WCI and their respective Subsidi aries (other than experimental  licenses in the
31 GHz and 38 GHz portion of the radio spectrum and licenses acquired from Local
Area  Telecommunications,  Inc.  that are not in the 38 GHz portion of the radio
spectrum) by the FCC (the  "Licenses").  All of the Licenses are currently valid
and in full force and effect.  Neither of the  Borrower and WCI nor any of their
respective  Subsidiaries  have any  knowledge  of any  investigation,  notice of
apparent liability,  violation, forfeiture or other order or complaint issued by
or before  any court or  regulatory  body,  including  the FCC,  or of any other
proceedings  (other than  proceedings  relating to the  wireless  communications
industries generally) which could in any manner materially threaten or adversely
affect the validity or continued effectiveness of any of the Licenses.

         (b) No event has  occurred  which (i)  results  in, or after  notice or
lapse  of  time  or  both  would  result  in,  revocation,  suspension,  adverse
modification,  non-renewal,  impairment, restriction or termination of, or order
of  forfeiture  with respect to, any License or (ii)  materially  and  adversely
affects or could  reasonably be expected in the future to  materially  adversely
affect  any of  the  rights  of the  Borrower,  WCI or any of  their  respective
Subsidiaries thereunder.

         (c)  Neither  of the  Borrower  and  WCI nor  any of  their  respective
Subsidiaries  have any reason to believe  that any of the  Licenses  will not be
renewed in the ordinary course.

                                   ARTICLE V.

                              Affirmative Covenants

         WCI and the  Borrower  covenant and agree with each Lender that so long
as this  Agreement  shall remain in effect and until the  Commitments  have been
terminated  and the  principal  of and  interest on each Loan,  all Fees and all
other  expenses or amounts  payable under any Loan Document shall have been paid
in full,  unless the Required  Lenders shall otherwise  consent in writing,  WCI
will, and will cause each Restricted Subsidiary to comply with the following:

         SECTION 5.01. Existence. Subject to Article VI, WCI will do or cause to
be done all things  necessary  to preserve and keep in full force and effect its
existence and the existence of each of its Restricted Subsidiaries in accordance
with the respective organizational documents of WCI and each such Subsidiary and
the rights (whether  pursuant to charter,  partnership  certificate,  agreement,
statute or  otherwise),  material  licenses and  franchises of WCI and each such
Subsidiary;  provided,  however,  that WCI shall not be required to preserve any
such right, license or franchise,


<PAGE>
                                                                           41

or the  existence  of any  Restricted  Subsidiary  (other  than of WCI),  if the
maintenance or preservation thereof is no longer desirable in the conduct of the
business of WCI and its Restricted Subsidiaries taken as a whole.

         SECTION  5.02.  Insurance.  (a) WCI will cause all  properties  used or
useful in the conduct of its business or the  business of any of its  Restricted
Subsidiaries,  to be  maintained  and kept in reasonable  condition,  repair and
working  order and supplied  with all  necessary  equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof,  all as in the  judgment of WCI may be  necessary  so that the business
carried on in connection therewith may be properly and advantageously  conducted
at all times; provided, however, that nothing in this Section 5.02 shall prevent
WCI or any such Subsidiary from  discontinuing the use, operation or maintenance
of any of such properties or disposing of any of them, if such discontinuance or
disposal is, in the judgment of WCI, desirable in the conduct of the business of
WCI or such Subsidiary.

         (b) WCI will  provide  or  cause to be  provided,  for  itself  and its
Restricted  Subsidiaries,   insurance  (including  appropriate   self-insurance)
against loss or damage of the kinds customarily  insured against by corporations
similarly  situated and owning like properties,  including,  but not limited to,
public liability  insurance,  with reputable  insurers or with the government of
the United States of America,  or an agency or instrumentality  thereof, in such
amounts,  with such  deductibles  and by such methods as shall be customary  for
corporations  similarly situated in the industry in which WCI or such Restricted
Subsidiary, as the case may be, is then conducting business.

         SECTION  5.03.  Obligations  and Taxes.  WCI will pay or discharge  and
shall cause each of its Subsidiaries to pay or discharge, or cause to be paid or
discharged,  before the same shall become  delinquent  (i) all  material  taxes,
assessments and governmental  charges levied or imposed upon (a) WCI or any such
Subsidiary,  (b) the  income  or  profits  of any  such  Subsidiary  which  is a
corporation  or (c) the  property  of WCI or any  such  Subsidiary  and (ii) all
material lawful claims for labor,  materials and supplies that, if unpaid, might
by law become a lien upon the property of WCI or any such Subsidiary;  provided,
however, that WCI shall not be required to pay or discharge, or cause to be paid
or  discharged,   any  such  tax,  assessment,   charge  or  claim  the  amount,
applicability  or  validity  of  which  is  being  contested  in good  faith  by
appropriate proceedings and for which adequate reserves have been established.

         SECTION 5.04. Defaults and Other Notices.  (a) In the event that WCI or
the  Borrower  becomes  aware of any  Default  or Event of  Default,  WCI or the
Borrower, as the case may be, promptly after it becomes aware thereof, will give
written notice thereof to the Administrative Agent.

         (b) Each of WCI and the Borrower  shall  deliver to the  Administrative
Agent,  within  90 days  after  the  end of  WCI's  fiscal  year,  an  Officers'
Certificate  stating  whether or not the signers know of any Default or Event of
Default that occurred during such fiscal year. Such certificates shall contain a
certification from the principal executive officer,  principal financial officer
or principal  accounting  officer of WCI and the Borrower that a review has been
conducted of the activities of WCI, the Borrower and the Restricted Subsidiaries
and WCI's,  the Borrower's and the Restricted  Subsidiaries'  performance  under
this Agreement and that, to the best knowledge of such officer,  each of WCI and
the Borrower has complied with all conditions and covenants under this

<PAGE>
                                                                            42

Agreement.  For  purposes  of  this  Section  5.04,  such  compliance  shall  be
determined  without  regard  to any  period  of grace or  requirement  of notice
provided under this Agreement.  If WCI or the Borrower knows of such an Event of
Default or Default,  the certificate shall describe any such Event of Default or
Default and its status.

         (c) WCI shall (to the extent not  prohibited by  applicable  accounting
rules) deliver to the Administrative  Agent, within 90 days after the end of its
fiscal  year,  a  certificate  signed  by  WCI's  independent  certified  public
accountants  stating (i) that their audit  examination  has included a review of
the terms of this Agreement and the Loans as they relate to accounting  matters,
(ii) that they have read the most recent Officers'  Certificate delivered to the
Administrative  Agent  pursuant to paragraph  (b) of this Section 5.04 and (iii)
whether,  in  connection  with their audit  examination,  anything came to their
attention that caused them to believe that WCI or the Borrower,  as the case may
be,  was not in  compliance  with any of the  terms,  covenants,  provisions  or
conditions of this  Agreement as it pertains to  accounting  matters and, if any
Default or Event of Default has come to their  attention,  specifying the nature
and  period of  existence  thereof;  provided,  however,  that such  independent
certified public accountants shall not be liable in respect of such statement by
reason  of any  failure  to obtain  knowledge  of any such  Default  or Event of
Default  that  would not be  disclosed  in the  course  of an audit  examination
conducted in accordance with generally  accepted auditing standards in effect at
the date of such examination.

         (d)  Within  90 days  after  the end of WCI's  fiscal  year,  WCI shall
deliver to the Administrative Agent a list of all Significant Subsidiaries.  The
Administrative  Agent shall have no duty with respect to any such list except to
keep it on file and available for inspection by the Lenders.

         (e) On or prior to  February  17,  1998,  the  Borrower  shall  deliver
written notice to the  Administrative  Agent of whether it intends to effect the
repayment of remaining Loans pursuant to Section 2.11 through (i) available cash
of the Borrower or (ii) the proceeds of a refinancing;  provided,  however, that
if the  aggregate  amount  of Loans  outstanding  on such  date are  equal to or
greater  than $40  million,  (x) in the event that the Borrower has notified the
Administrative  Agent of its intention to make repayment  pursuant to clause (i)
above, the Borrower will deliver to the Administrative  Agent information on its
current and projected cash balances in such detail as the  Administrative  Agent
reasonably  requests,  and (y) in the event that the  Borrower  has notified the
Administrative  Agent of its intention to make repayment pursuant to clause (ii)
above, the Borrower shall, in accordance with the Fee Letter, use its good faith
efforts to consummate  such  refinancing  prior to the Term Loan Maturity  Date;
provided,  however, that the Borrower's  notification of its intentions pursuant
to this clause (e) shall not create a binding  obligation to effect repayment in
such manner.

                                   ARTICLE VI.

                               Negative Covenants

         WCI and the Borrower  covenant and agree with each Lender that, so long
as this  Agreement  shall remain in effect and until the  Commitments  have been
terminated  and the  principal  of and  interest on each Loan,  all Fees and all
other  expenses or amounts  payable under any Loan Document shall have been paid
in full,  unless the Required  Lenders shall otherwise  consent in writing,  WCI
will and will cause each Restricted Subsidiary to comply with the following:

         SECTION 6.01.  Limitation on  Indebtedness.  (a) WCI will not, and will
not permit any of its Restricted  Subsidiaries to, Incur any Indebtedness (other
than the  Loans  and  Indebtedness  existing  on the  Closing  Date);  provided,
however,  that  WCI may  Incur  Indebtedness  if,  after  giving  effect  to the
Incurrence of such  Indebtedness and the receipt and application of the proceeds
therefrom,  the Indebtedness to EBITDA Ratio would be greater than zero and less
than 5:1.

         Notwithstanding  the  foregoing,  WCI  and  any  Restricted  Subsidiary
(except as specified below) may Incur each and all of the following:

                  (i)  Indebtedness  of  WCI  outstanding  at  any  time  in  an
         aggregate principal amount not to exceed $125,000,000,  less any amount
         of  Indebtedness  Incurred  pursuant to this clause (i) and permanently
         repaid  as  provided  under  Section  4.11  of the  August  1997  Notes
         Indenture;

                  (ii)  Indebtedness  (A) to WCI evidenced by an  unsubordinated
         promissory note or (B) to any of its Restricted Subsidiaries; provided,
         however, that any event which results in any such Restricted Subsidiary
         ceasing to be a Restricted  Subsidiary  or any  subsequent  transfer of
         such Indebtedness (other than to WCI or another Restricted  Subsidiary)
         shall be deemed,  in each case,  to  constitute  an  Incurrence of such
         Indebtedness not permitted by this clause (ii);

                  (iii) Indebtedness issued in exchange for, or the net proceeds
         of  which  are  used  to   refinance   or  refund,   then   outstanding
         Indebtedness, other than Indebtedness Incurred under

                                                                           44

         clause  (i),  (ii),  (v),  (vi) or  (viii) of this  paragraph,  and any
         refinancings  thereof  in  an  amount  not  to  exceed  the  amount  so
         refinanced  or refunded  (plus  premiums,  accrued  interest,  fees and
         expenses);  provided,  however, that Indebtedness the proceeds of which
         are used to refinance or refund the Loans or Indebtedness  that is pari
         passu with, or  subordinated  in right of payment to, the WCI Guarantee
         shall  only be  permitted  under this  clause  (iii) if (A) in case the
         Loans are  refinanced in part or the  Indebtedness  to be refinanced is
         pari passu with the WCI Guarantee, such new Indebtedness,  by its terms
         or by the terms of any agreement or  instrument  pursuant to which such
         new Indebtedness is outstanding,  is expressly made pari passu with, or
         subordinate in right of payment to, the WCI Guarantee,  (B) in case the
         Indebtedness  to be refinanced is  subordinated  in right of payment to
         the WCI Guarantee, such new Indebtedness,  by its terms or by the terms
         of any agreement or instrument  pursuant to which such new Indebtedness
         is  outstanding,  is expressly made  subordinate in right of payment to
         the WCI  Guarantee at least to the extent that the  Indebtedness  to be
         refinanced  is  subordinated  to the WCI  Guarantee  and (C)  such  new
         Indebtedness,  determined  as of the  date of  Incurrence  of such  new
         Indebtedness,  does not  mature  prior to the  Stated  Maturity  of the
         Indebtedness to be refinanced or refunded, and the Average Life of such
         new Indebtedness is at least equal to the remaining Average Life of the
         Indebtedness to be refinanced or refunded;  provided further,  however,
         that in no event may  Indebtedness of WCI be refinanced by means of any
         Indebtedness  of any  Restricted  Subsidiary  of WCI  pursuant  to this
         clause (iii);

                  (iv)  Indebtedness  (A) in respect of  performance,  surety or
         appeal  bonds  provided in the ordinary  course of business,  (B) under
         Currency  Agreements and Interest Rate Agreements;  provided,  however,
         that such  agreements do not increase the  Indebtedness  of the obligor
         outstanding  at any time  other  than as a result  of  fluctuations  in
         foreign currency exchange rates or interest rates or by reason of fees,
         indemnities and compensation  payable thereunder;  and (C) arising from
         agreements providing for indemnification,  adjustment of purchase price
         or similar obligations, or from Guarantees or letters of credit, surety
         bonds or performance  bonds  securing any  obligations of WCI or any of
         the Restricted  Subsidiaries  pursuant to such agreements,  in any case
         Incurred in connection with the disposition of any business,  assets or
         Restricted  Subsidiary of WCI (other than  Guarantees  of  Indebtedness
         Incurred by any Person  acquiring all or any portion of such  business,
         assets or  Restricted  Subsidiary  of WCI for the purpose of  financing
         such  acquisition),  in a  principal  amount  not to  exceed  the gross
         proceeds  actually  received  by WCI or any  Restricted  Subsidiary  in
         connection with such disposition;

                  (v)  Indebtedness  of WCI  not to  exceed,  at  any  one  time
         outstanding,  two times the Net Cash Proceeds  received by WCI from and
         after October 23, 1995, from the issuance and sale of its Capital Stock
         (other than Redeemable  Stock and Preferred Stock that provides for the
         payment  of  dividends   in  cash);   provided,   however,   that  such
         Indebtedness  (x) does not mature prior to the Term Loan  Maturity Date
         and has an Average  Life longer than the Loans and (y) is  subordinated
         to the WCI Guarantee at least to the extent that the Convertible  Notes
         are subordinated to Senior  Indebtedness (as defined in the Convertible
         Notes Indenture as in effect on the Closing Date);

                  (vi)  Indebtedness  of  any  Restricted   Subsidiary  Incurred
         pursuant  to any credit  agreement  of such  Restricted  Subsidiary  in
         effect on the Closing Date (and refinancings thereof), up to the


<PAGE>

                                                                           45

         amount of  the  commitment  under  such credit agreement on the Closing
         Date;

                  (vii)  Indebtedness to the extent such Indebtedness is secured
         by Liens  which are  purchase  money or other Liens upon  equipment  or
         inventory acquired or held by WCI or any of its Restricted Subsidiaries
         taken or  obtained  by (A) the  seller or lessor of such  equipment  or
         inventory  to  secure  all or a part of the  purchase  price  or  lease
         payments  therefor  or (B) the  person  who  makes  advances  or incurs
         obligations,  thereby  giving  value to WCI to enable it to purchase or
         acquire rights in such equipment or inventory,  to secure the repayment
         of all or a part of the  advances so made or  obligations  so incurred;
         provided,  however,  that  such  Liens do not  extend  to or cover  any
         property or assets of WCI or any Restricted  Subsidiary  other than the
         equipment or inventory acquired; and

                  (viii)  Indebtedness  of  any  Restricted  Subsidiary  not  to
         exceed, at any one time outstanding, 80% of the accounts receivable net
         of  reserves  and  allowances  for  doubtful  accounts,  determined  in
         accordance with GAAP, of such Restricted  Subsidiary and its Restricted
         Subsidiaries  (without  duplication);   provided,  however,  that  such
         Indebtedness  is not  Guaranteed  by  WCI  or  any  of  its  Restricted
         Subsidiaries.

         (b) For purposes of determining  any particular  amount of Indebtedness
under this  Section  6.01,  Guarantees,  Liens or  obligations  with  respect to
letters  of  credit   supporting   Indebtedness   otherwise   included   in  the
determination of such particular  amount shall not be included.  For purposes of
determining  compliance  with this  Section  6.01,  in the event that an item of
Indebtedness  meets the  criteria of more than one of the types of  Indebtedness
described in the above clauses, WCI, in its sole discretion, shall classify such
item of Indebtedness and only be required to include the amount and type of such
Indebtedness in one of such clauses.

         (c) WCI will not,  and will not permit any  Restricted  Subsidiary  to,
Incur any Guarantee of Indebtedness of any Unrestricted Subsidiary.

         SECTION 6.02. Limitation on Restricted Payments. WCI will not, and will
not permit any Restricted Subsidiary to, directly or indirectly,  (i) declare or
pay any  dividend  or make any  distribution  on its Capital  Stock  (other than
dividends or  distributions  payable solely in shares of its or such  Restricted
Subsidiary's Capital Stock (other than Redeemable Stock) held by such holders or
in options,  warrants or other rights to acquire  such shares of Capital  Stock)
other than such Capital Stock held by WCI or any of its Restricted  Subsidiaries
(and  other  than  pro  rata  dividends  or  distributions  on  Common  Stock of
Restricted Subsidiaries);  (ii) repurchase,  redeem, retire or otherwise acquire
for value any shares of Capital  Stock of WCI  (including  options,  warrants or
other rights to acquire such shares of Capital Stock) held by Persons other than
any Wholly Owned  Restricted  Subsidiaries  of WCI;  (iii) make any voluntary or
optional principal  payment,  or voluntary or optional  redemption,  repurchase,
defeasance, or other acquisition or retirement for value, of Indebtedness of WCI
that is subordinated in right of payment to the WCI Guarantee;  or (iv) make any
Investment,  other than a Permitted Investment,  in any Person (such payments or
any other  actions  described  in clauses  (i) through  (iv) being  collectively
"Restricted  Payments")  if, at the time of,  and after  giving  effect  to, the
proposed  Restricted  Payment:  (A) a Default  or Event of  Default  shall  have
occurred and be  continuing,  (B) except with respect to any  Investment  (other
than an Investment  consisting of the designation of a Restricted  Subsidiary as
an Unrestricted Subsidiary),

                                                                           46


WCI could not Incur at least $1.00 of Indebtedness  under the first paragraph of
Section 6.01 or (C) the aggregate  amount  expended for all Restricted  Payments
(the amount so expended,  if other than in cash,  to be determined in good faith
by the Board of Directors, whose determination shall be conclusive and evidenced
by a Board Resolution) after the Closing Date shall exceed the sum of (1) 50% of
the  aggregate  amount of the  Adjusted  Consolidated  Net  Income  (or,  if the
Adjusted  Consolidated  Net  Income  is a  loss,  minus  100%  of  such  amount)
(determined by excluding  income  resulting from transfers of assets by WCI or a
Restricted  Subsidiary to an  Unrestricted  Subsidiary)  accrued on a cumulative
basis during the period (taken as one accounting  period) beginning on the first
day of the fiscal quarter  immediately  following the Closing Date and ending on
the last day of the last fiscal quarter preceding the Transaction Date for which
reports have been filed with the SEC plus (2) the  aggregate  Net Cash  Proceeds
received by WCI after the Closing Date from the  issuance and sale  permitted by
this  Agreement of its Capital Stock (other than  Redeemable  Stock) to a Person
who is not a  Subsidiary  of WCI, or from the  issuance to a Person who is not a
Subsidiary  of WCI of any options,  warrants or other rights to acquire  Capital
Stock  of  WCI  (in  each  case,  exclusive  of  any  convertible  Indebtedness,
Redeemable Stock or any options, warrants or other rights that are redeemable at
the option of the Holder, or are required to be redeemed, prior to the Term Loan
Maturity  Date) plus (3) an amount  equal to the net  reduction  in  Investments
(other than  reductions in Permitted  Investments  and other than  reductions in
Investments  made  pursuant to clauses (vi) or (vii) of the second  paragraph of
this  Section  6.02) in any  Person  resulting  from  payments  of  interest  on
Indebtedness,  dividends, repayments of loans or advances, or other transfers of
assets, in each case to WCI or any Restricted  Subsidiary  (except to the extent
any such payment is included in the  calculation  of Adjusted  Consolidated  Net
Income),  or from  redesignations  of  Unrestricted  Subsidiaries  as Restricted
Subsidiaries   (valued  in  each  case  as   provided  in  the   definition   of
"Investments"),  not to exceed the amount of Investments  previously made by WCI
and its Restricted Subsidiaries in such Person.

         The foregoing provision shall not be violated by reason of:

                  (i) the payment of any dividend  within 60 days after the date
         of declaration  thereof if, at said date of  declaration,  such payment
         would comply with the foregoing paragraph;

                  (ii)  the   redemption,   repurchase,   defeasance   or  other
         acquisition   or  retirement   for  value  of   Indebtedness   that  is
         subordinated  in  right  of  payment  to the WCI  Guarantee,  including
         premium, if any, and accrued and unpaid interest, with the proceeds of,
         or in exchange  for,  Indebtedness  Incurred  under clause (iii) of the
         second paragraph of Section 6.01;

                  (iii)  the  repurchase,  redemption  or other  acquisition  of
         Capital  Stock of WCI (or options,  warrants or other rights to acquire
         such  Capital  Stock) in  exchange  for,  or out of the  proceeds  of a
         substantially  concurrent  sale of, shares of Capital Stock or options,
         warrants or other rights to purchase  such Capital  Stock (in each case
         other than Redeemable Stock) of WCI;

                  (iv)  the  making  of any  other  Restricted  Payment  made by
         exchange  for, or out of the  proceeds of, a  substantially  concurrent
         sale of,  shares of the  Capital  Stock or  options,  warrants or other
         rights  to  acquire  such  Capital  Stock  (in  each  case  other  than
         Redeemable Stock) of the Borrower;

                                                                           47

                  (v) payments or  distributions,  in the nature of satisfaction
         of   dissenters'   rights,   pursuant  to  or  in  connection   with  a
         consolidation,  merger or  transfer of assets  that  complies  with the
         provisions of this Agreement applicable to mergers,  consolidations and
         transfers  of all or  substantially  all of the  property and assets of
         WCI;

                  (vi)  Investments,  not to exceed  $15,000,000 at any one time
outstanding;

                  (vii)  Investments,  not to exceed $15,000,000 at any one time
         outstanding,  in  entities,  substantially  all of the  assets of which
         consist of Telecommunications Assets;

                  (viii) (A) cash payments in lieu of the issuance of fractional
         shares of Common Stock upon conversion (including mandatory conversion)
         of  the  Convertible  Notes  provided  for  in  the  Convertible  Notes
         Indenture and (B) cash payments on the Convertible Notes required to be
         made under  Section  4.12 and  Section  4.13 in the  Convertible  Notes
         Indenture (as in effect on the Closing Date);

                  (ix)  cash  payments  in lieu of the  issuance  of  fractional
         shares of Common Stock of WCI upon conversion of any class of Preferred
         Stock of WCI;  provided,  however,  that  this  exception  shall not be
         available with respect to more than two such  conversions  with respect
         to any such class of Preferred Stock by any given Affiliate of WCI; and

                  (x)  Investments  in entities  that  directly  (or  indirectly
         through  subsidiaries)  own  licenses  granted  by the FCC or any other
         governmental   entity  with   authority  to  grant   telecommunications
         licenses;  provided,  however,  that,  in each case WCI or a Restricted
         Subsidiary shall, at the time of making such Investment, have an active
         role in the management or operation of such entity and in the provision
         of telecommunications services by such entity;

provided,  however,  that,  except in the case of clauses  (i) and (iii) of this
paragraph,  no Default or Event of Default shall have occurred and be continuing
or occur as a  consequence  of the actions or  payments  set forth  herein.  Any
Investments made other than in cash shall be valued, in good faith, by the Board
of  Directors.  Any  Investment  made  pursuant  to clause (vi) or (vii) of this
paragraph  shall be deemed to be no longer  outstanding  (and repaid in full) if
and when the  Person in which  such  Investment  is made  becomes  a  Restricted
Subsidiary of WCI.

         Each Restricted Payment permitted  pursuant to the preceding  paragraph
(other than the Restricted Payment referred to in clause (ii) thereof),  and the
Net Cash  Proceeds  from any issuance and sale of Capital  Stock  referred to in
clauses (iii) or (iv) shall be included in calculating whether the conditions of
clause  (C) of the  first  paragraph  of this  Section  6.02  have been met with
respect to any subsequent  Restricted Payments.  In the event the proceeds of an
issuance of Capital  Stock of WCI are used for the repayment of the Loans or the
redemption,  repurchase or other  acquisition of Indebtedness that is pari passu
with the WCI  Guarantee  then the Net Cash  Proceeds of such  issuance  shall be
included in clause (C) of the first  paragraph  of this Section 6.02 only to the
extent  such  proceeds  are not used for such  redemption,  repurchase  or other
acquisition of Indebtedness.

     SECTION  6.03.  Limitation  on  Dividend  and  Other  Payment  Restrictions
Affecting  Restricted  Subsidiaries.  WCI will  not,  and will  not  permit  any
Restricted Subsidiary to, create or

                                                                           48

otherwise  cause  or  suffer  to  exist  or  become   effective  any  consensual
encumbrance  or  restriction  of any  kind  on  the  ability  of any  Restricted
Subsidiary to:

                  (i) pay dividends or make any other distributions permitted by
         applicable law on any Capital Stock of such Restricted Subsidiary owned
         by WCI or any other Restricted Subsidiary;

                  (ii) pay any Indebtedness  owed to WCI or any other Restricted
         Subsidiary that owns, directly or indirectly, any Capital Stock of such
         Restricted Subsidiary;

                  (iii) make loans or  advances  to WCI or any other  Restricted
         Subsidiary that owns, directly or indirectly, any Capital Stock of such
         Restricted Subsidiary; or

                  (iv)  transfer  any of its  property  or  assets to WCI or any
         other  Restricted  Subsidiary  that owns,  directly or indirectly,  any
         Capital Stock of such Restricted Subsidiary.

         The  foregoing  provisions  shall  not  prohibit  any  encumbrances  or
restrictions:

                  (i)  existing on the  Closing  Date in this  Agreement  or any
         other  agreement  in effect on the Closing  Date,  and any  extensions,
         refinancings,  renewals or replacements of such  agreements;  provided,
         however, that the encumbrances and restrictions in any such extensions,
         refinancings,  renewals or  replacements  are no less  favorable in any
         material respect to the Holders than those encumbrances or restrictions
         that  are then in  effect  and that  are  being  extended,  refinanced,
         renewed or replaced;

                  (ii) existing under or by reason of applicable law;

                  (iii)  existing  with respect to any Person or the property or
         assets of such Person acquired by WCI or any Restricted Subsidiary,  at
         the time of such acquisition and not incurred in contemplation thereof,
         which  encumbrances or restrictions are not applicable to any Person or
         the  property  or assets of any Person  other  than such  Person or the
         property or assets of such Person so acquired;

                  (iv) in the case of clause (iv) of the first paragraph of this
         Section 6.03, (A) that restrict in a customary  manner the  subletting,
         assignment  or  transfer  of any  property  or  asset  that is a lease,

         Restricted Subsidiary not otherwise prohibited by this Agreement or (C)
         arising or agreed to in the ordinary  course of business,  not relating
         to any Indebtedness, and that do not, individually or in the aggregate,
         detract  from the value of property or assets of WCI or any  Restricted
         Subsidiary in any manner material to WCI or any Restricted  Subsidiary;
         or

                  (v)  with  respect  to a  Restricted  Subsidiary  and  imposed
         pursuant to an  agreement  that has been  entered  into for the sale or

Nothing  contained  in this  Section  6.03 shall  prevent WCI or any  Restricted
Subsidiary  from (i)  restricting  the sale or other  disposition of property or
assets of WCI or any of its Restricted  Subsidiaries that secure Indebtedness of
WCI or any of its Restricted Subsidiaries or (ii) creating,  incurring, assuming
or suffering to exist any Liens otherwise permitted under Section 6.07.

         SECTION 6.04. Limitation on the Issuance of Capital Stock of Restricted
Subsidiaries.  WCI will not sell, and will not permit any Restricted Subsidiary,
directly  or  indirectly,  to issue or sell any  shares  of  Capital  Stock of a
Restricted Subsidiary  (including options,  warrants or other rights to purchase
shares of such Capital Stock) except:

                  (i)  to WCI or a Wholly Owned Restricted Subsidiary;

                  (ii)  issuances  or sales to  foreign  nationals  of shares of
         Capital  Stock  of  foreign  Restricted  Subsidiaries,  to  the  extent
         required by applicable law;

                  (iii) if,  immediately after giving effect to such issuance or
         sale,  such  Restricted   Subsidiary  would  no  longer   constitute  a
         Restricted Subsidiary; or

                  (iv)   issuances  or  sales  of  Common  Stock  of  Restricted
         Subsidiaries,   other  than  the  Telecommunications   Subsidiaries  in
         compliance with Section 6.09.

         SECTION  6.05.  Limitation  on Issuances of  Guarantees  by  Restricted
Subsidiaries.  WCI  will not  permit  any  Restricted  Subsidiary,  directly  or
indirectly,  to Guarantee any Indebtedness of WCI  ("Guaranteed  Indebtedness"),
unless (i) such  Restricted  Subsidiary  simultaneously  executes and delivers a
supplemental   amendment  to  this  Agreement   providing  for  a  Guarantee  (a
"Subsidiary  Guarantee") of payment of the Loans by such  Restricted  Subsidiary
and (ii) such Restricted Subsidiary waives and will not in any manner whatsoever
claim  or take the  benefit  or  advantage  of,  any  rights  of  reimbursement,
indemnity or subrogation or any other rights against WCI or any other Restricted
Subsidiary as a result of any payment by such  Restricted  Subsidiary  under its
Subsidiary  Guarantee;  provided,  however,  that  this  paragraph  shall not be
applicable to any Guarantee of any Restricted Subsidiary that (x) existed at the
time such Person  became a  Restricted  Subsidiary  and (y) was not  Incurred in
connection  with,  or in  contemplation  of, such Person  becoming a  Restricted
Subsidiary.  If the  Guaranteed  Indebtedness  is (A)  pari  passu  with the WCI
Guarantee,  then the  Guarantee of such  Guaranteed  Indebtedness  shall be pari
passu with, or subordinated to, the Subsidiary  Guarantee or (B) subordinated to
the WCI Guarantee then the Guarantee of such  Guaranteed  Indebtedness  shall be
subordinated  to the  Subsidiary  Guarantee  at  least  to the  extent  that the
Guaranteed Indebtedness is subordinated to the WCI Guarantee.

         Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary  shall  provide  by its  terms  that it  shall be  automatically  and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any  Person  not an  Affiliate  of WCI of all of WCI's  and  each  Restricted
Subsidiary's  Capital Stock in, or all or substantially  all the assets of, such
Restricted  Subsidiary  (which sale,  exchange or transfer is not  prohibited by
this Agreement) or (ii) the release or discharge of the Guarantee which resulted
in the creation of such Subsidiary  Guarantee,  except a discharge or release by
or as a result of payment under such Guarantee.

         SECTION  6.06.   Limitation  on  Transactions   with  Shareholders  and
Affiliates.  WCI will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly , enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the  rendering  of any  service)  with any holder (or any  Affiliate  of such
holder) of 5% or more of any class of Capital Stock of WCI or with any Affiliate
of WCI or any Restricted  Subsidiary,  except upon fair and reasonable  terms no
less favorable to WCI or such Restricted  Subsidiary than could be obtained,  at
the time of such  transaction  or, if such  transaction is pursuant to a written
agreement,  at the time of the execution of the agreement providing therefor, in
a comparable arm's-length transaction with a Person that is not such a holder or
an Affiliate.

         The  foregoing  limitation  does not limit,  and shall not apply to (i)
transactions  (A)  approved  by a majority of the  disinterested  members of the
Board of Directors or (B) for which WCI or a Restricted  Subsidiary  delivers to
the Administrative Agent a written opinion of a nationally recognized investment
banking  firm  stating that the  transaction  is fair to WCI or such  Restricted
Subsidiary from a financial  point of view; (ii) any transaction  solely between
WCI and any of its Wholly Owned Restricted Subsidiaries or solely between Wholly
Owned Restricted Subsidiaries; (iii) the payment of reasonable fees to directors
of WCI who are not  employees of WCI;  (iv) any  payments or other  transactions

which  WCI  files a  consolidated  tax  return  or with  which  WCI is part of a
consolidated  group  for  tax  purposes;  or (v)  any  Restricted  Payments  not
prohibited by the provisions of Section 6.02 (other than pursuant to clause (iv)
of the  definition  of  "Permitted  Investment"  or  clause  (vi) of the  second
paragraph of Section  6.02).  Notwithstanding  the  foregoing,  any  transaction
covered by the first  paragraph  of this Section 6.06 and not covered by clauses
(ii) through  (iv) of this  paragraph,  the  aggregate  amount of which  exceeds
$250,000  in value,  must be  approved  or  determined  to be fair in the manner
provided for in clause (i)(A) or (B) above.

         SECTION 6.07.  Limitation  on Liens.  WCI will not, and will not permit
any Restricted  Subsidiary to, create, incur, assume or suffer to exist any Lien
on any of its assets or  properties of any  character,  or any shares of Capital
Stock or Indebtedness  of any Restricted  Subsidiary  (collectively,  "Protected
Property"),  without  making  effective  provision for the WCI Guarantee and all
other amounts due under this Agreement or any other Loan Document to be directly
secured  equally and ratably  with (or, if the  obligation  or  liability  to be
secured by such Lien is  subordinated  in right of payment to the WCI  Guarantee
prior to) the obligation or liability secured by such Lien.

         The foregoing limitation does not apply to:

                  (i)  Liens existing on the Closing Date;

                  (ii) Liens  granted  after the  Closing  Date on any assets or
         Capital Stock of WCI or its Restricted Subsidiaries created in favor of
         the Holders;

                  (iii)  Liens  with  respect  to  the  assets  of a  Restricted
         Subsidiary  granted by such  Restricted  Subsidiary  to WCI or a Wholly
         Owned Restricted Subsidiary to secure Indebtedness owing to WCI or such
         other Restricted Subsidiary;

                  (iv)  Liens  securing   Indebtedness   which  is  Incurred  to
         refinance secured  Indebtedness which is permitted to be Incurred under
         clause (iii) of the second paragraph

                                                                           51

         of Section 6.01; provided, however, that such Liens do not extend to or
         cover any property or assets of WCI or any Restricted  Subsidiary other
         than the property or assets securing the Indebtedness being refinanced;

                  (v) Liens securing Indebtedness Incurred pursuant to the first
         sentence of Section 6.01;

         acquired or held by WCI or any of its Restricted  Subsidiaries taken or
         obtained by (A) the seller or lessor of such  equipment or inventory to
         secure all or a part of the purchase price or lease  payments  therefor
         or (B) the person who makes  advances  or incurs  obligations,  thereby
         giving value to WCI to enable it to purchase or acquire  rights in such
         equipment or inventory, to secure the repayment of all or a part of the
         advances so made or obligations so incurred;  provided,  however,  that
         such Liens do not extend to or cover any  property  or assets of WCI or
         any  Restricted  Subsidiary  other  than  the  equipment  or  inventory
         acquired; or

                  (vii)  Permitted Liens.

         SECTION 6.08. Limitation on Sale-Leaseback Transactions.  WCI will not,
and will not permit any Restricted  Subsidiary to, enter into any sale-leaseback
transaction  involving  any of its  assets or  properties  whether  now owned or
hereafter  acquired,  whereby WCI or a Restricted  Subsidiary sells or transfers
such  assets  or  properties  and  then or  thereafter  leases  such  assets  or
properties  or any part thereof or any other assets or  properties  which WCI or
such Restricted Subsidiary, as the case may be, intends to use for substantially
the same purpose or purposes as the assets or properties sold or transferred.

         The  foregoing   restriction  does  not  apply  to  any  sale-leaseback
transaction if:

more than three years;

                  (ii) the lease  secures or relates  to  industrial  revenue or

                  (iii) the  transaction  is solely  between  WCI and any Wholly
         Owned  Restricted  Subsidiary or solely between Wholly Owned Restricted
         Subsidiaries;

                  (iv) the assets or properties  are sold and leased back within
         30 days of the date  that  the  account  payable  with  respect  to the
         acquisition  by WCI or any  Restricted  Subsidiary  of such  assets  or
         properties is due and payable; or

                  (v) WCI or such  Restricted  Subsidiary  complies with Section
6.09.

         SECTION  6.09.  Limitation  on Asset Sales.  WCI will not, and will not
permit any Restricted  Subsidiary to,  consummate any Asset Sale, unless (i) the

the  consideration  received  consists of cash or  Temporary  Cash  Investments.
Without limiting the foregoing, in the case of an Asset Sale with respect to the
Collateral 100% of the consideration  received must consist of cash or temporary
cash Investments and an amount equal

to the lesser of 100% of the Net Cash Proceeds of any Asset Sale with respect to
the  Collateral  or the then  outstanding  amount of the Loans  shall be used to
prepay  outstanding  Loans on the date of such  Asset  Sale in  accordance  with
Section 2.13.

         SECTION  6.10.  Waiver of Stay,  Extension or Usury Laws.  The Borrower
covenants  (to the extent  that it may  lawfully  do so) that it will not at any
time  insist  upon,  or plead,  or in any  manner  whatsoever  claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
that would  prohibit or forgive the  Borrower  from paying all or any portion of
the  principal  of,  premium,  if any, or interest on the Loans as  contemplated
herein,  wherever  enacted,  now or at any time hereafter in force,  or that may
affect the covenants or the  performance of this  Agreement;  and (to the extent
that it may lawfully do so) the Borrower hereby  expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Administrative  Agent, but will
suffer and permit  the  execution  of every such power as though no such law had
been enacted.

         SECTION 6.11.  Mergers,  Consolidations,  Etc. of WCI and the Borrower.
(a) WCI  shall  not  consolidate  with,  merge  with or into,  or sell,  convey,

and assets (as an entirety or  substantially an entirety in one transaction or a
series of related  transactions)  to, any Person (other than a consolidation  or
merger with or into a Wholly  Owned  Restricted  Subsidiary  with a positive net
worth;  provided,   however,  that,  in  connection  with  any  such  merger  or
consolidation, no consideration (other than Common Stock in the surviving Person
or WCI) shall be issued or distributed to the stockholders of WCI) or permit any
Person to merge with or into WCI unless:

                  (i) WCI shall be the  continuing  Person,  or the  Person  (if
         other  than WCI)  formed  by such  consolidation  or into  which WCI is
         merged or that acquired or leased such property and assets of WCI shall
         be a corporation  organized and validly  existing under the laws of the
         United  States  of  America  or  any  jurisdiction  thereof  and  shall
         expressly assume, by a supplemental  agreement,  executed and delivered
         to the  Administrative  Agent,  all of the obligations of WCI on all of
         the Loans and under this Agreement;

                  (ii) immediately after giving effect to such  transaction,  no
         Default or Event of Default shall have occurred and be continuing;

                  (iii) immediately after giving effect to such transaction on a
         pro forma basis,  WCI or any Person  becoming the successor  obligor of
         the Loans shall have a Consolidated  Net Worth equal to or greater than
         the   Consolidated   Net  Worth  of  WCI  immediately   prior  to  such
         transaction;

                  (iv) immediately  after giving effect to such transaction on a
         pro forma basis WCI, or any Person  becoming the  successor  obligor of
         the Loans could Incur at least  $1.00 of  Indebtedness  under the first
         paragraph of Section 6.01; and

                  (v) WCI  delivers  to the  Administrative  Agent an  Officers'

         compliance with clauses (iii) and, if applicable,  (iv)) and Opinion of
         Counsel,  in each  case  stating  that  such  consolidation,  merger or
         transfer and such supplemental  indenture  complies with the provisions

          all   conditions   precedent  provided  for  herein  relating to such
          transaction have been complied with;

provided,  however,  that  clauses  (iii) and (iv) above do not apply if, in the
good faith  determination of the Board of Directors of WCI, whose  determination
shall  be  evidenced  by a  Board  Resolution,  the  principal  purpose  of such
transaction is to change the state of  incorporation of WCI;  provided  further,
however,  that any such  transaction  shall not have as one of its  purposes the
evasion of the foregoing limitations.

         (b) The Borrower  shall not  consolidate  with,  merge with or into, or
sell, convey, transfer, lease (other than in the ordinary course of business) or
otherwise dispose of all or substantially all of its property and assets to, any

or other  disposition of all or substantially  all of the property and assets of
WCI or the Borrower,  as the case may be, in accordance  with this Section 6.11,
the  successor  Person  formed by such  consolidation  or into  which WCI or the
Borrower,  as the case may be,  is  merged or to which  such  sale,  conveyance,
transfer or other  disposition is made shall succeed to, and be substituted for,
and may exercise every right and power of, WCI or the Borrower,  as the case may
be, under this Agreement  with the same effect as if such  successor  Person had
been named as WCI or the Borrower, as the case may be, herein.

         SECTION 6.12.  Limitation on the Borrower's  Business  Activities.  The
Borrower shall not, and WCI shall not permit the Borrower to,

Administrative  Agent may, and at the request of the Required  Lenders shall, by
notice to the  Borrower,  take either or both of the following  actions,  at the
same or different  times:  (i)  terminate  forthwith  the  Commitments  and (ii)
declare the Loans then  outstanding  to be forthwith due and payable in whole or
in part, whereupon the principal of the Loans so declared to be due and payable,
together with accrued interest thereon and any unpaid accrued Fees and all other
liabilities of the Borrower accrued hereunder and under any other Loan Document,
shall become forthwith due and payable, without presentment,  demand, protest or
any other notice of any kind,  all of which are hereby  expressly  waived by the
Borrower,  anything  contained  herein  or in any  other  Loan  Document  to the
contrary  notwithstanding;  and in any event with respect to WCI or the Borrower
described in paragraph (g) or (h) above,  the  Commitments  shall  automatically

interest  thereon and any unpaid  accrued Fees and all other  liabilities of the
Borrower   accrued   hereunder  and  under  any  other  Loan   Document,   shall

                                  ARTICLE VIII.

               The Syndication Agent and the Administrative Agent

         In order to expedite the  transactions  contemplated by this Agreement,
Salomon  Brothers  Inc is  hereby  appointed  to act as  Syndication  Agent  and
Administrative  Agent on behalf of the Lenders  (for  purposes  of this  Article
VIII,  the  Syndication  Agent  and the  Administrative  Agent are  referred  to
collectively as the "Agents"). Each of the Lenders and each assignee of any such
Lender hereby  irrevocably  authorizes the Agents to take such actions on behalf
of such Lender or  assignee  and to  exercise  such  powers as are  specifically
delegated to the Agents by the terms and provisions hereof and of the other Loan
Documents,  together with such actions and powers as are  reasonably  incidental
thereto. The Administrative Agent is hereby expressly authorized by the Lenders,
without hereby limiting any implied  authority,  (a) to receive on behalf of the
Lenders all  payments of  principal  of and  interest on the Loans and all other
amounts due to the Lenders hereunder,  and promptly to distribute to each Lender
its proper share of each  payment so  received;  (b) to give notice on behalf of
each of the Lenders to the  Borrower of any Event of Default  specified  in this
Agreement of which the  Administrative  Agent has actual  knowledge  acquired in
connection  with its agency  hereunder;  and (c) to  distribute  to each  Lender
copies of all notices, financial statements and other materials delivered by the
Borrower or any other Loan Party  pursuant to this  Agreement  or the other Loan
Documents  as  received  by  the  Administrative  Agent.  Without  limiting  the
generality  of the  foregoing,  the Agents are hereby  expressly  authorized  to
execute  any  and  all  documents  (including  releases)  with  respect  to  the
Collateral  and the rights of the  Secured  Parties  with  respect  thereto,  as
contemplated  by and in accordance with the provisions of this Agreement and the
Security Documents.

         Neither  the Agents nor any of their  respective  directors,  officers,
employees  or agents  shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct,  or
be responsible for any statement, warranty or representation


<PAGE>
                                                                           57

herein or the contents of any document delivered in connection  herewith,  or be
required to  ascertain  or to make any inquiry  concerning  the  performance  or
observance  by the  Borrower  or  any  other  Loan  Party  of any of the  terms,
conditions,  covenants or agreements contained in any Loan Document.  The Agents
shall not be  responsible  to the  Lenders for the due  execution,  genuineness,
validity,  enforceability  or  effectiveness of this Agreement or any other Loan
Documents,  instruments  or  agreements.  The Agents shall in all cases be fully
protected in acting,  or  refraining  from acting,  in  accordance  with written
instructions   signed  by  the  Required   Lenders  and,   except  as  otherwise
specifically  provided  herein,  such  instructions  and any action or  inaction
pursuant  thereto shall be binding on all the Lenders.  Each Agent shall, in the
absence of knowledge to the contrary,  be entitled to rely on any  instrument or
document believed by it in good faith to be genuine and correct and to have been
signed or sent by the proper  person or  persons.  Neither the Agents nor any of
their  respective  directors,  officers,  employees  or  agents  shall  have any
responsibility to the Borrower or any other Loan Party on account of the failure
of or delay in  performance  or breach by any  Lender of any of its  obligations
hereunder or to any Lender on account of the failure of or delay in  performance
or breach by any other  Lender or the Borrower or any other Loan Party of any of
their  respective  obligations  hereunder or under any other Loan Document or in
connection  herewith  or  therewith.  Each of the Agents may execute any and all
duties hereunder by or through agents or employees and shall be entitled to rely
upon the advice of legal  counsel  selected  by it with  respect to all  matters
arising  hereunder  and shall not be liable for any action  taken or suffered in
good faith by it in accordance with the advice of such counsel.

         The Lenders  hereby  acknowledge  that neither Agent shall be under any
duty to take any  discretionary  action  permitted to be taken by it pursuant to
the provisions of this  Agreement  unless it shall be requested in writing to do
so by the Required Lenders.

         Subject to the  appointment  and  acceptance  of a  successor  Agent as
provided below, either Agent may resign at any time by notifying the Lenders and
the  Borrower.  Upon any such  resignation,  the  retiring  Agent shall have the
right, on behalf of the Lenders, to appoint a successor reasonably acceptable to
the  Borrower  from  among  the  Lenders.  If no  successor  shall  have been so
appointed by the retiring Agent and shall have accepted such appointment  within
30 days after the  retiring  Agent  gives  notice of its  resignation,  then the
Required  Lenders may  appoint a successor  Agent which shall be a bank having a
combined  capital and surplus of at least  $500,000,000  or an  Affiliate of any
such bank.  Upon the  acceptance  of any  appointment  as Agent  hereunder  by a
successor  bank,  such successor shall succeed to and become vested with all the
rights,  powers,  privileges  and duties of the retiring  Agent and the retiring
Agent shall be discharged from its duties and obligations  hereunder.  After the
Agent's resignation  hereunder,  the provisions of this Article and Section 9.05
shall  continue  in effect for its  benefit in respect of any  actions  taken or
omitted to be taken by it while it was acting as Agent.

         With respect to the Loans, if any, made by it hereunder,  each Agent in
its  individual  capacity and not as Agent shall have the same rights and powers
as any other  Lender and may  exercise  the same as though it were not an Agent,
and the Agents and their  Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower,  WCI or any of their
respective Subsidiaries or other Affiliate thereof as if it were not an Agent.

         Each  Lender  agrees (a) to  reimburse  the Agents,  on demand,  in the
amount  of its pro  rata  share  (based  on its  Commitments  hereunder)  of any
expenses incurred for the benefit of the Lenders


<PAGE>
                                                                           58

by the Agents,  including  counsel fees and compensation of agents and employees
paid for services  rendered on behalf of the  Lenders,  that shall not have been
reimbursed by the Borrower and (b) to indemnify and hold harmless each Agent and
any of its directors, officers, employees or agents, on demand, in the amount of
such  pro  rata  share,  from  and  against  any  and  all  liabilities,  taxes,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements  of any kind or nature  whatsoever that may be imposed
on,  incurred by or asserted  against it in its capacity as Agent or any of them
in any way  relating  to or  arising  out of this  Agreement  or any other  Loan
Document  or any  action  taken  or  omitted  by it or any of  them  under  this
Agreement or any other Loan Document, to the extent the same shall not have been
reimbursed  by the  Borrower  or any other Loan Party,  provided  that no Lender
shall be liable to an Agent or any such other indemnified person for any portion
of  such  liabilities,   obligations,   losses,  damages,  penalties,   actions,
judgments,  suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or wilful misconduct of such Agent or any of its directors,
officers, employees or agents.

         Each  Lender  acknowledges  that  it  has,  independently  and  without
reliance  upon the Agents or any other  Lender and based on such  documents  and
information  as it has  deemed  appropriate,  made its own credit  analysis  and
decision to enter into this  Agreement.  Each Lender also  acknowledges  that it
will, independently and without reliance upon the Agents or any other Lender and
based on such  documents  and  information  as it shall  from  time to time deem
appropriate,  continue to make its own  decisions in taking or not taking action
under or based upon this  Agreement  or any other  Loan  Document,  any  related
agreement or any document furnished hereunder or thereunder.


                                   ARTICLE IX

                                    Guarantee

         SECTION 9.01. Guarantee. The Guarantor  unconditionally and irrevocably
guarantees to each Lender and to the Administrative Agent and its successors and
assigns (a) the full and  punctual  payment of  principal of and interest on the
Loans  when  due,  whether  at  maturity,  by  acceleration,  by  redemption  or
otherwise,  and all  other  monetary  obligations  of the  Borrower  under  this
Agreement and each other Loan Document and (b) the full and punctual performance
within  applicable grace periods of all other  obligations of the Borrower under
this Agreement and the other Loan Documents (all the foregoing being hereinafter
collectively called the "Guaranteed Obligations").  The Guarantor further agrees
that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice or further assent from the Guarantor, and that the Guarantor will
remain bound under this Article IX  notwithstanding  any extension or renewal of
any Guaranteed Obligation.

         The  Guarantor  waives  presentation  to,  demand of,  payment from and
protest to the  Borrower of any of the  Guaranteed  Obligations  and also waives
notice of protest for  nonpayment.  The  Guarantor  waives notice of any default
under the Guaranteed  Obligations.  The  obligations of the Guarantor  hereunder
shall not be  affected  by (a) the  failure of any Lender or the  Administrative
Agent to assert  any claim or demand or to enforce  any right or remedy  against
the  Borrower  or any other  Person  under  this  Agreement,  or any other  Loan
Documents or otherwise; (b) any extension


<PAGE>
                                                                             59

or renewal of any thereof; (c) any rescission, waiver, amendment or modification
of any of the terms or provisions of this Agreement or any other Loan Documents;
(d) the release of any security held by any Lender or the  Administrative  Agent
for the Guaranteed  Obligations or any of them; (e) the failure of any Lender or
the  Administrative  Agent to  exercise  any right or remedy  against  any other
guarantor of the Guaranteed  Obligations;  or (f) any change in the ownership of
the Guarantor.

         The Guarantor  further agrees that its Guarantee  herein  constitutes a
guarantee of payment,  performance  and compliance when due (and not a guarantee
of collection)  and waives any right to require that any resort be had by Lender
or the  Administrative  Agent to any security held for payment of the Guaranteed
Obligations.

         The obligations of the Guarantor  hereunder shall not be subject to any
reduction,  limitation,  impairment or termination for any reason, including any
claim of waiver, release, surrender,  alteration or compromise, and shall not be
subject to any  defense  of  setoff,  counterclaim,  recoupment  or  termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed  Obligations  or otherwise.  Without  limiting the  generality of the
foregoing,  the  obligations of the Guarantor  herein shall not be discharged or
impaired   or   otherwise   affected  by  the  failure  of  any  Lender  or  the
Administrative  Agent to assert  any claim or demand or to  enforce  any  remedy
under this Agreement or any other Loan Document,  by any waiver or  modification
of any thereof, by any default,  failure or delay, willful or otherwise,  in the
performance  of the  obligations,  or by any other act or thing or  omission  or
delay to do any  other act or thing  which may or might in any  manner or to any
extent vary the risk of the Guarantor or would otherwise  operate as a discharge
of the Guarantor as a matter of law or equity.

         The Guarantor  further agrees that its Guarantee  herein shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof,  of principal of or interest on any  Guaranteed  Obligation is
rescinded  or must  otherwise  be restored  by any Lender or the  Administrative
Agent upon the bankruptcy or reorganization of the Borrower or otherwise.

         In  furtherance  of the  foregoing  and not in  limitation of any other
right  which  any  Lender  or the  Administrative  Agent has at law or in equity
against the Guarantor by virtue hereof,  upon the failure of the Borrower to pay
the principal of or interest on any Guaranteed  Obligation  when and as the same
shall  become due,  whether at  maturity,  by  acceleration,  by  redemption  or
otherwise,  or to perform or comply with any other  Guaranteed  Obligation,  the
Guarantor  hereby  promises to and will,  upon receipt of written  demand by the
Administrative  Agent,  forthwith  pay,  or cause to be  paid,  in cash,  to the
Lenders or the Administrative Agent an amount equal to the sum of (i) the unpaid
amount of such Guaranteed Obligations,  (ii) accrued and unpaid interest on such
Guaranteed  Obligations (but only to the extent not prohibited by law) and (iii)
all other monetary Guaranteed Obligations of the Borrower to the Lenders and the
Administrative Agent.

         The  Guarantor  agrees  that it shall not be  entitled  to any right of
subrogation in respect of any  Guaranteed  Obligations  guaranteed  hereby until
payment in full of all  Guaranteed  Obligations.  The Guarantor  further  agrees
that,  as  between  it, on the one hand,  and the  Lender or the  Administrative
Agent,  on the  other  hand,  (x) the  maturity  of the  Guaranteed  Obligations
guaranteed hereby may be accelerated as provided in Article VII for the purposes
of the Guarantor's  Guarantee herein,  notwithstanding  any stay,  injunction or
other  prohibition  preventing  such  acceleration  in respect of the Guaranteed
Obligations guaranteed hereby, and (y) in the event of any declaration of


<PAGE>
                                                                           60

acceleration  of such  obligations  as provided in Article VII, such  Guaranteed
Obligations  (whether or not due and  payable)  shall  forthwith  become due and
payable by the Guarantor for the purposes of this Section 9.01.

         The  Guarantor  also  agrees  to pay  any and all  costs  and  expenses
(including  reasonable  attorneys' fees) incurred by the Administrative Agent or
any Lender in enforcing any rights under this Section.

         SECTION 9.02.  Successors and Assigns. This Article IX shall be binding
upon the Guarantor and its successors and assigns and shall enure to the benefit
of the successors and assigns of the  Administrative  Agent and the Lenders and,
in the event of any  transfer  or  assignment  of  rights  by any  Lender or the
Administrative  Agent,  the rights and  privileges  conferred upon that party in
this Agreement and in the other Loan Documents shall automatically extend to and
be  vested  in such  transferee  or  assignee,  all  subject  to the  terms  and
conditions of this Agreement.

         SECTION 9.03.  No Waiver.  Neither a failure nor a delay on the part of
either the Administrative Agent or the Lenders in exercising any right, power or
privilege under this Article IX shall operate as a waiver  thereof,  nor shall a
single or partial exercise thereof preclude any other or further exercise of any
right,   power  or  privilege.   The  rights,   remedies  and  benefits  of  the
Administrative  Agent and the Lenders herein expressly  specified are cumulative
and not  exclusive of any other  rights,  remedies or benefits  which either may
have under this Article IX at law, in equity, by statute or otherwise.

                  SECTION  9.04.  Modification.  No  modification,  amendment or
waiver of any  provision of this Article IX, nor the consent to any departure by
the Guarantor  therefrom,  shall in any event be effective unless the same shall
be in writing and signed by the  Administrative  Agent,  and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given.  No notice to or demand on the  Guarantor in any case shall entitle
the Guarantor to any other or further  notice or demand in the same,  similar or
other circumstances.


                                   ARTICLE X.

         (b) Each Lender may assign to one or more assignees all or a portion of

assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and (B) the assigning  Lender  thereunder  shall, to
the extent of the  interest  assigned  by such  Assignment  and  Acceptance,  be
released  from its  obligations  under this  Agreement  (and,  in the case of an
Assignment and Acceptance  covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall  continue to be entitled to the benefits of Sections
2.14,  2.16,  2.19 and 10.05, as well as to any Fees accrued for its account and
not yet paid).

         (c) By executing  and  delivering  an Assignment  and  Acceptance,  the
assigning  Lender  thereunder  and the  assignee  thereunder  shall be deemed to
confirm to and agree with each other and the other  parties  hereto as  follows:
(i) such assigning  Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim and that
its Term Loan  Commitment,  and the  outstanding  balances of its Loans, in each
case  without  giving  effect  to  assignments  thereof  which  have not  become
effective,  are as set forth in such Assignment and  Acceptance,  (ii) except as
set  forth in (i)  above,  such  assigning  Lender  makes no  representation  or
warranty  and  assumes  no  responsibility   with  respect  to  any  statements,
warranties or representations  made in or in connection with this Agreement,  or
the execution, legality, validity, enforceability,  genuineness,  sufficiency or
value of this  Agreement,  any other Loan  Document or any other  instrument  or
document furnished pursuant hereto, or the financial  condition of the Borrower,
WCI or any of their respective  Subsidiaries or the performance or observance by
the  Borrower,  WCI  or  any  of  their  respective  Subsidiaries  of any of its
obligations  under  this  Agreement,  any  other  Loan  Document  or  any  other
instrument or document furnished pursuant hereto; (iii) such assignee represents
and warrants  that it is legally  authorized to enter into such  Assignment  and
Acceptance;  (iv) such  assignee  confirms  that it has  received a copy of this
Agreement, together with copies of the most recent financial statements referred
to in Section  3.06(a) and those  delivered  pursuant  to Section  5.08 and such
other  documents and  information  as it has deemed  appropriate to make its own
credit analysis and decision to enter into such  Assignment and Acceptance;  (v)
such  assignee will  independently  and without  reliance  upon the  Syndication
Agent, the  Administrative  Agent, such assigning Lender or any other Lender and
based on such  documents and  information  as it shall deem  appropriate  at the
time,  continue to make its own credit  decisions in taking or not taking action
under this Agreement; (vi) such assignee appoints and authorizes the Syndication
Agent and the  Administrative  Agent to take such  action as agent on its behalf
and to  exercise  such  powers  under this  Agreement  as are  delegated  to the
Syndication  Agent  and the  Administrative  Agent,  respectively,  by the terms
hereof,  together with such powers as are  reasonably  incidental  thereto;  and
(vii) such assignee  agrees that it will perform in accordance  with their terms
all the  obligations  which by the terms of this  Agreement  are  required to be
performed by it as a Lender.

         (d) The  Administrative  Agent,  acting for this purpose as an agent of
the  Borrower,  shall  maintain  at one of its offices in The City of New York a
copy of each  Assignment and  Acceptance  delivered to it and a register for the
recordation  of the names and addresses of the Lenders,  and the  Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms

                                                                           63

hereof from time to time (the "Register").  The entries in the Register shall be
conclusive and the Borrower, the Syndication Agent, the Administrative Agent and
the  Lenders  may treat each  person  whose  name is  recorded  in the  Register
pursuant  to the terms  hereof as a Lender  hereunder  for all  purposes of this
Agreement,  notwithstanding  notice  to the  contrary.  The  Register  shall  be
available for inspection by the Borrower,  the Syndication Agent and any Lender,
at any reasonable time and from time to time upon reasonable prior notice.

         (e) Upon its  receipt of a duly  completed  Assignment  and  Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee  (unless the  assignee  shall  already be a
Lender  hereunder),  the processing and recordation fee referred to in paragraph
(b) above and, if required,  the written consent of the Administrative Agent and
the Borrower to such assignment,  the Administrative Agent shall (i) accept such
Assignment and Acceptance,  (ii) record the information contained therein in the
Register  and (iii) give prompt  notice  thereof to the Lenders.  No  assignment
shall be  effective  unless it has been  recorded in the Register as provided in
this paragraph (e).

         (f)  Each  Lender  may  without  the  consent  of the  Borrower  or the
Administrative  Agent sell participations to one or more financial  institutions
in  all  or a  portion  of its  rights  and  obligations  under  this  Agreement
(including  all or a  portion  of its  Commitment  and the  Loans  owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged,  (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations,  (iii) the participating
financial  institutions  shall be entitled to the benefit of the cost protection
provisions  contained in Sections  2.14,  2.16 and 2.19 to the same extent as if
they  were  Lenders  and (iv) the  Borrower,  the  Administrative  Agent and the
Lenders  shall  continue  to deal  solely  and  directly  with  such  Lender  in
connection with such Lender's rights and obligations  under this Agreement,  and
such  Lender  shall  retain  the sole right to enforce  the  obligations  of the
Borrower  relating to the Loans and to approve any  amendment,  modification  or
waiver of any provision of this Agreement (other than amendments,  modifications
or waivers  decreasing any fees payable  hereunder or the amount of principal of
or the rate at which  interest is payable on the Loans,  extending any scheduled
principal payment date or date fixed for the payment of interest on the Loans or
increasing or extending the Commitments).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed  assignment or participation  pursuant to this Section
10.04,  disclose  to  the  assignee  or  participant  or  proposed  assignee  or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower;  provided  that,  prior to any such  disclosure of
information  designated by the Borrower as  confidential,  each such assignee or
participant  or proposed  assignee or  participant  shall  execute an  agreement
whereby  such  assignee  or  participant   shall  agree  (subject  to  customary
exceptions) to preserve the confidentiality of such confidential information.

         (h) Any Lender may at any time  assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank to secure extensions of credit by
such Federal Reserve Bank to such Lender; provided that no such assignment shall
release a Lender from any of its  obligations  hereunder or substitute  any such
Bank  for  such  Lender  as a party  hereto.  In  order  to  facilitate  such an
assignment to a Federal  Reserve Bank, the Borrower shall, at the request of the
assigning Lender,

                                                                           64

duly  execute and deliver to the  assigning  Lender a  promissory  note or notes
evidencing the Loans made to the Borrower by the assigning Lender hereunder.

         (i) The  Borrower  shall not  assign or  delegate  any of its rights or
duties hereunder without the prior written consent of the  Administrative  Agent
and each Lender, and any attempted assignment without such consent shall be null
and void.

        SECTION 10.05.  Expenses;  Indemnity.  (a)  The Borrower  agrees  to pay
all of the Fees referenced in the Fee Letter.

         (b) The Borrower  agrees to indemnify  the  Administrative  Agent,  the
Syndication  Agent  and each  Lender,  each  Affiliate  of any of the  foregoing
persons and each of their respective directors,  officers,  employees and agents
(each  such  person  being  called an  "Indemnitee")  against,  and to hold each
Indemnitee harmless from, any and all losses, claims,  damages,  liabilities and
related expenses,  including  reasonable  counsel fees,  disbursements and other
charges incurred by or asserted against any Indemnitee arising out of any claim,
litigation,  investigation  or  proceeding,  whether or not any  Indemnitee is a
party thereto, relating to, in any way connected with, or resulting from (i) the
execution  or  delivery  of this  Agreement  or any other Loan  Document  or any
agreement or instrument  contemplated  thereby,  the  performance by the parties
thereto of their  respective  obligations  thereunder or the consummation of the
Acquisition,  the Transactions and the other transactions  contemplated thereby,
(ii) the use of the  proceeds  of the  Loans  or (iii)  any  actual  or  alleged
presence or Release of Hazardous  Materials on any property owned or operated by
the Borrower or any Subsidiary, or any Environmental Claim related in any way to
the Borrower or any  Subsidiary;  provided that such indemnity  shall not, as to
any Indemnitee,  be available to the extent that such losses,  claims,  damages,
liabilities  or  related  expenses  are  determined  by  a  court  of  competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

         (c) The provisions of this Section 10.05 shall remain  operative and in
full  force  and  effect  regardless  of the  expiration  of the  term  of  this
Agreement,  the  consummation  of  the  transactions  contemplated  hereby,  the
repayment of any of the Loans, the expiration of the Commitments, the invalidity
or unenforceability of any term or provision of this Agreement or any other Loan
Document, or any investigation made by or on behalf of the Administrative Agent,
the  Syndication  Agent or any Lender.  All amounts due under this Section 10.05
shall be payable on written demand therefor.


         SECTION 10.06.  Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
LAWS OF THE STATE OF NEW YORK.

         SECTION  10.07.  Waivers;  Amendment.  (a) No  failure  or delay of the
Administrative  Agent,  the  Syndication  Agent or any Lender in exercising  any
power or 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 or
power, or any abandonment or  discontinuance of steps to enforce such a right or
power,  preclude  any other or further  exercise  thereof or the exercise of any
other right or power. The rights and remedies of the  Administrative  Agent, the
Syndication Agent and the Lenders


<PAGE>
                                                                           65

hereunder  and  under  the  other  Loan  Documents  are  cumulative  and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any  provision of this  Agreement  or any other Loan  Document or consent to any
departure by the Borrower or any other Loan Party  therefrom  shall in any event
be effective unless the same shall be permitted by paragraph (b) below, 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  provision  hereof may be waived,
amended or modified  except  pursuant to an agreement or  agreements  in writing
entered into by the Borrower and the Required Lenders;  provided,  however, that
no such  agreement  shall (i)  decrease the  principal  amount of, or extend the
maturity of or any scheduled  principal  payment date or date for the payment of
any  interest  on any Loan,  or waive or  excuse  any such  payment  or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender affected thereby, (ii) change or extend the Commitment of
any Lender without the prior written  consent of such Lender,  or (iii) amend or
modify the  provisions  of Section  2.17 or  10.04(i),  the  provisions  of this
Section,  the definition of the term "Required Lenders" or release any Guarantor
or all or any  substantial  part of the  Collateral,  without the prior  written
consent of each Lender;  provided  further that no such  agreement  shall amend,
modify or otherwise affect the rights or duties of the  Administrative  Agent or
the  Syndication  Agent  hereunder or under any other Loan Document  without the
prior written consent of the Administrative Agent or the Syndication Agent.

         SECTION  10.08.  Interest  Rate  Limitation.  Notwithstanding  anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees,  charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted  for,  charged,
taken,  received or reserved by the Lender holding such Loan in accordance  with
applicable law, the rate of interest  payable in respect of such Loan hereunder,
together with all Charges  payable in respect  thereof,  shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been  payable in  respect  of such Loan but were not  payable as a result of the
operation of this Section  10.08 shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods  shall be  increased
(but not above the Maximum Rate therefor) until such cumulated amount,  together
with  interest  thereon  at the  Federal  Funds  Effective  Rate to the  date of
repayment, shall have been received by such Lender.

         SECTION 10.09. Entire Agreement. This Agreement, the Fee Letter and the
other Loan Documents constitute the entire contract between the parties relative
to the subject matter hereof.  Any other  previous  agreement  among the parties
with respect to the subject  matter hereof is  superseded by this  Agreement and
the other  Loan  Documents.  Nothing  in this  Agreement  or in the  other  Loan
Documents, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies,  obligations or liabilities
under or by reason of this Agreement or the other Loan Documents.

         SECTION 10.10.  Waiver of Jury Trial.  EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT


<PAGE>
                                                                           66

OR ANY OF THE OTHER LOAN  DOCUMENTS.  EACH PARTY  HERETO (A)  CERTIFIES  THAT NO
REPRESENTATIVE,  AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,  SEEK
TO  ENFORCE  THE  FOREGOING  WAIVER AND (B)  ACKNOWLEDGES  THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS,  AS  APPLICABLE,  BY,  AMONG  OTHER  THINGS,  THE MUTUAL  WAIVERS AND
CERTIFICATIONS IN THIS SECTION 10.10.

         SECTION  10.11.  Severability.  In the  event  any  one or  more of the
provisions  contained in this Agreement or in any other Loan Document  should be
held 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 (it being  understood that
the invalidity of a particular provision in a particular  jurisdiction shall not
in  and  of  itself  affect  the  validity  of  such   provision  in  any  other
jurisdiction).  The parties shall endeavor in good-faith negotiations to replace
the invalid,  illegal or  unenforceable  provisions  with valid  provisions  the
economic  effect of which  comes as close as  possible  to that of the  invalid,
illegal or unenforceable provisions.

         SECTION  10.12.  Counterparts.   This  Agreement  may  be  executed  in
counterparts (and by different parties hereto on different  counterparts),  each
of which shall constitute an original but all of which when taken together shall
constitute a single contract,  and shall become effective as provided in Section
10.03.  Delivery of an executed  signature  page to this  Agreement by facsimile
transmission  shall be as effective as delivery of a manually signed counterpart
of this Agreement.

         SECTION 10.13. Headings.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement  and are not to  affect  the  construction  of,  or to be  taken  into
consideration in interpreting, this Agreement.

         SECTION 10.14. No Recourse Against Others.  No recourse for the payment
of the  principal of or inteest on any Loan,  or for anyclaim  based  thereon or
otherwise  in respect  thereof,  and no recourse  under or upon any  obligation,
covenant or  agreement of the  Borrower or WCI  contained  in this  Agreement or
because of the creation of any Indebtedness  represented therreby,  shall be had
against  the  incorporator,   stockholder,   officer,   director,   employee  or
controlling  person,  as such, of the Borroer,  WCI or of any  successor  Person
thereof in such capacity; provided, however, that the foregoing shall not affect
WCI's  obligations  with  respect  to the  WCI  Guarantee;  it  being  expressly
unerstood that all such liability is hereby  expressly  waivedand  released as a
condition of, and as consideration for, the execution of this Agreement.

     SECTION  10.15.  Jurisdiction;  Consent  to  Service  of  Process.  (a) The
Borrower and WCI hereby irrevocably and  unconditionally  submit, for themselves
and their property, to the nonexclusive jurisdiction of any New York State court
or Federal court of the United States of America  sitting in New York City,  and
any appellate court from any thereof, in any action or proceeding arising out of
or relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment,  and each of the parties hereto hereby  irrevocably
and  unconditionally  agrees  that all claims in  respect of any such  action or
proceeding  may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each

of the  parties  hereto  agrees  that a final  judgment  in any such  action  or
proceeding  shall be conclusive  and may be enforced in other  jurisdictions  by
suit on the  judgment or in any other  manner  provided by law.  Nothing in this
Agreement shall affect any right that the Administrative  Agent, the Syndication
Agent or any  Lender  may  otherwise  have to bring  any  action  or  proceeding
relating to this Agreement or the other Loan Documents against the Borrower, WCI
or their respective proper ties in the courts of any jurisdiction.

         (b) The Borrower and WCI hereby irrevocably and unconditionally  waive,
to the fullest extent it may legally and  effectively do so, any objection which
either may now or hereafter  have to the laying of venue of any suit,  action or
proceeding  arising  out of or  relating  to this  Agreement  or the other  Loan
Documents  in any New York State or Federal  court.  Each of the parties  hereto
hereby  irrevocably  waives, to the fullest extent permitted by law, the defense
of an inconvenient  forum to the maintenance of such action or proceeding in any
such court.

          (c) Each party to this  Agreement  irrevocably consents to service of
process by  registered   mail  at  the addresses  provided for in Section 10.01.

and  protect  the  validity of and to  establish  a legal,  valid and  perfected
security interest in favor of the Administrative  Agent (for the ratable benefit
of the  Secured  Parties)  in respect of all  Collateral  in which the  Security
Interest  may be perfected by filing,  recording or  registration  in the United
States  (or  any  political   subdivision   thereof)  and  its  territories  and
possessions,   and  no  further  or  subsequent  filing,  refiling,   recording,

name,  location  or  organizational  form  and to  changes  in the  location  of

         SECTION 4.01. Change of Name; Location of Collateral; Records; Place of
Business. (a) The Grantor agrees promptly to notify the Administrative Agent, in
writing,  of any  change  (i) in its  legal  name or in any  trade  name used to
identify  it in  the  conduct  of  its  business  or in  the  ownership  of  its
properties,  (ii) in the location of its chief executive  office,  its principal
place of business, any office in which it maintains books or records relating to
Collateral owned by it or any office or facility at which Collateral owned by it
is located  (including  the  establishment  of any such new office or facility),
(iii)  in its  identity  or  legal  structure  or (iv) in its  Federal  Taxpayer
Identification  Number(s). The Grantor agrees not to effect or permit any change
referred to in the  preceding  sentence  unless all filings have been made under
the Uniform  Commercial  Code or  otherwise  that are  required in order for the
Administrative  Agent to continue at all times  following  such change to have a
valid,  legal and preferred first priority (subject to liens expressly  referred
to  Section  3.18  of  the  Credit  Agreement)  security  interest  in  all  the
Collateral.  The Grantor agrees to notify the  Administrative  Agent, as soon as
practicable  after an executive  officer of the Grantor learns  thereof,  if any
material  portion of the  Collateral  owned or held by the Grantor is damaged or
destroyed.

         (b) The Grantor agrees to maintain,  at its own cost and expense,  such
complete and accurate records with respect to the Collateral owned or held by it
as is consistent with its current  practices and in accordance with such prudent
and standard  practices  used in  industries  that are the same as or similar to
those in which the  Grantor is  engaged,  but in any event to  include  complete
accounting records indicating all payments and proceeds received with respect to
any part of the  Collateral,  and,  at such time or times as the  Administrative
Agent  may  reasonably   request,   promptly  to  prepare  and  deliver  to  the
Administrative  Agent a duly certified  schedule or schedules in form and detail
reasonably satisfactory to the Administrative Agent showing the identity, amount
and location of any and all Collateral.

         SECTION 4.02.  Protection of Security.  The Grantor  shall,  at its own
cost and expense,  take any and all actions reasonably necessary to defend title
to the Collateral against all persons and to defend the Security Interest of the
Administrative Agent in the Collateral and the priority thereof against any Lien
not expressly referred to in Section 3.18 of the Credit Agreement.

         SECTION  4.03.  Continuation  Statements.  The Grantor  agrees,  at its
expense,  to execute,  acknowledge,  deliver and cause to be duly filed all such
further  instruments  and  documents  and  to  take  all  such  actions  as  the
Administrative  Agent may from time to time reasonably request to better assure,
protect,  perfect and preserve the Security Interest and the rights and remedies
created  hereby,  including  the  payment  of any fees  and  taxes  required  in
connection  with the execution and delivery of this  Agreement,  the granting of
the  Security  Interest  and the  filing of any  financing  statements  or other
documents in connection herewith or therewith. If any amount payable under or in
connection with any of the Collateral shall

                                                                           6

instrument  shall be  immediately  pledged and  delivered to the  Administrative
Agent, duly endorsed in a manner satisfactory to the Administrative Agent.

         SECTION 4.04. Inspection and Verification. The Administrative Agent and
such persons as the  Collateral  Agent may reasonably  designate  shall have the
right,  at the Grantor's own cost and expense,  to inspect the  Collateral,  all
records  related thereto (and to make extracts and copies from such records) and
the premises upon which any of the Collateral is located, where such premises is
within the control of the Grantor or any  affiliate of the  Grantor,  to discuss
the  Grantor's  affairs  with the  officers of the  Grantor and its  independent
accountants  and to verify under  reasonable  procedures  the validity,  amount,
quality,  quantity, value, condition and status of, or any other matter relating
to, the  Collateral,  including,  in the case of Collateral in the possession of
any third  person,  by contacting  the third party  possessing  such  Collateral
(after  two days'  notice  to the  Grantor)  for the  purpose  of making  such a
verification. Where the premises upon which any of the Collateral is located are
not within the control of the Grantor, the Grantor shall reasonably request such
person(s)  controlling such premises to allow the  Administrative  Agent and its
designees  to  inspect  such  premises  for the  purposes,  and  subject  to the
limitations,  of the foregoing sentence. The Administrative Agent shall have the
absolute  right to share  any  information  it gains  from  such  inspection  or
verification with any Secured Party.

         SECTION 4.05. Taxes; Encumbrances. At its option, upon not less than 10
days'  prior  written  notice  to the  Grantor,  the  Administrative  Agent  may
discharge past due taxes, assessments,  charges, fees, liens, security interests
or other  encumbrances  at any time levied or placed on the  Collateral  and not
permitted  under  the  Credit  Agreement,   may  pay  for  the  maintenance  and
preservation  of the  Collateral  (including  amounts  due in  respect  of  real
property leases pursuant to which the Grantor occupies premises in or upon which
Collateral  is located) to the extent the Grantor  fails to do so as required by
the Credit  Agreement  or this  Agreement,  and may pay any amounts  owed by the
Grantor  in order to cure any  default  in any lease  with  respect  to any real
property  in or on which  Collateral  is  situated  and the  Grantor  agrees  to
reimburse the Administrative Agent on demand for any reasonable payment or other
expenses  incurred  by  the  Administrative  Agent  pursuant  to  the  foregoing
authorization;  provided,  however,  that  nothing  in  this  Section  shall  be
interpreted  as excusing  the Grantor from the  performance  of, or imposing any
obligation on the Administrative  Agent or any Secured Party to cure or perform,
any  covenants  or  other  promises  of  the  Grantor  with  respect  to  taxes,
assessments,  charges, fees, liens, security interests or other encumbrances and
maintenance as set forth herein or in the other Loan Documents.

         SECTION 4.06. Continuing  Obligations of the Grantor. The Grantor shall
remain liable to observe and perform all the  conditions  and  obligations to be
observed  and  performed  by it under each  contract,  agreement  or  instrument
relating to the  Collateral,  all in  accordance  with the terms and  conditions
thereof,   and  the  Grantor   agrees  to  indemnify   and  hold   harmless  the
Administrative  Agent  and the  Secured  Parties  from and  against  any and all
liability for such performance.

         SECTION 4.07.  Insurance.  (a) The Grantor,  at its own expense,  shall
maintain or cause to be maintained insurance covering physical loss or damage to
the  Designated  Equipment,  in  accordance  with  Section  5.02  of the  Credit
Agreement.   The  Grantor  irrevocably  makes,   constitutes  and  appoints  the
Administrative  Agent (and all officers,  employees or agents  designated by the
Administrative   Agent)  as  the   Grantor's   true  and   lawful   agent   (and
attorney-in-fact)  for the  purpose,  during  the  continuance  of an  Event  of
Default, of making, settling and adjusting claims in respect of Collateral under
policies of insurance,  endorsing  the name of the Grantor on any check,  draft,
instrument  or other  item of  payment  for the  proceeds  of such  policies  of
insurance and for making all determinations and decisions with respect thereto.

         (b) In the event that the  Grantor  at any time or times  shall fail to
obtain or maintain any of the policies of  insurance  required  hereby or to pay
any premium in whole or part relating  thereto,  the  Administrative  Agent may,
without  waiving  or  releasing  any  obligation  or  liability  of the  Grantor
hereunder or any Event of Default,  in its sole discretion,  obtain and maintain
such  policies of insurance and pay such premium and take any other actions with
respect thereto as the Administrative Agent deems advisable.  All sums disbursed
by  the  Administrative  Agent  in  connection  with  this  Section,   including
reasonable  attorneys'  fees,  court costs,  expenses and other charges relating
thereto,  shall be payable,  upon demand,  by the Grantor to the  Administrative
Agent and shall be additional Obligations secured hereby.

         SECTION 4.08.  Posting of Notices.  The Grantor shall,  with respect to
any  telecommunications  switch that constitutes  Designated  Equipment,  post a
notice  on,  or  in  the  location  housing,  such  telecommunications   switch,
identifying  the  Grantor  as the  owner of the  telecommunications  switch  and
stating that such telecommunications  switch is subject to the Security Interest
under the Credit Agreement and the Loan Documents.


                                    ARTICLE V

                        Transfer and Sales of Collateral

         SECTION 5.01. Transfer and Sales of Collateral.  (a) Grantor shall not,
except as  permitted by the terms of the Credit  Agreement  from time to time in
effect,  sell, assign (by operation of law or otherwise) or otherwise dispose of
any  of  the  Collateral.  Notwithstanding  the  foregoing,  Grantor  may  lease
Designated  Equipment in the ordinary  course of business to an Affiliate of the
Grantor without such lease constituting a sale,  assignment or other disposition
prohibited by the preceding sentence,  and any consideration received by Grantor
in  respect  of any  such  lease  as  payments  pursuant  to such  lease  may be
transferred  by the Grantor  free and clear of such  security  interests  in the
Collateral  until  such  time  as an  Event  of  Default  has  occurred  and  is
continuing;  provided, however, that any such lease shall expressly provide that
it may  be  terminated  immediately  without  liability  to  the  lessee  by the
Administrative  Agent or any other Person designated by the Administrative Agent
if an Event of  Default  shall  have  occurred  and be  continuing  and that the
Administrative Agent or such

                                                                              8

designee may sell any or all Collateral  subject to such lease free and clear of
any claims against such Collateral or the proceeds thereof by the lessee.

         (b)  As  long  as no  Event  of  Default  shall  have  occurred  and be
continuing,  and no event which,  with the lapse of time or after notice,  would
become an Event of Default shall have occurred and be continuing,  Grantor shall
be entitled from time to time to request the Administrative Agent to release all
or a  portion  of the  Collateral  owned by it and  subject  to this  Agreement;
provided,  however,  that such request must be in writing and  accompanied by an
Officers'  Certificate  of Grantor  and an Opinion of Counsel to Grantor  (which
counsel shall be reasonably  satisfactory to the  Administrative  Agent) stating
that all conditions precedent to the release of such Collateral pursuant to this
Article V and the Credit Agreement have been complied with. Upon satisfaction of
the  conditions  in this  Article V and the Credit  Agreement,  the Lien of this
Agreement on all Collateral  shall be released without any further action on the
part of the  Administrative  Agent or any other person.  In  furtherance  of the
foregoing,  the  Administrative  Agent  shall  execute and deliver to Grantor an
instrument or instruments acknowledging the release of such Collateral from this
Agreement  and the  discharge  of the Lien on such  Collateral  created  by this
Agreement,  and will duly  assign,  transfer  and  deliver to  Grantor  (without
recourse and without any  representation  or  warranty)  such  Collateral  to be
released.

         (c) No  Collateral  shall be released  from the Lien of this  Agreement
pursuant  to any  request  described  in  paragraph  (b)  above  unless  (i) the
Administrative  Agent shall,  in its sole  discretion,  consent to such release,
(ii) as  promptly as is  practicable  thereafter,  the  Grantor  shall sell such
Collateral,  (iii) at the  closing of such sale,  the  Grantor  provides  to the
Administrative Agent, in order to reduce the outstanding principal amount of the
Loans, cash or cash equivalents representing the Net Cash Proceeds from the sale
of such  Collateral  (which  shall be no less than the fair market value of such
Collateral);  and (iv) Grantor delivers to the Administrative Agent an Officers'
Certificate  and an  Opinion  of  Counsel  to the  effect  that  all  conditions
precedent  contained  in the Credit  Agreement  to the sale and  release of such
Collateral shall have been satisfied in full.

         (d) The  release  of any  Collateral  from the terms  hereof and of the
other Loan  Documents or the release of, in whole or in part,  the Liens created
by the Loan  Documents,  will not be deemed to impair the Lien on the Collateral
in  contravention of the provisions of the Credit Agreement if and to the extent
the Collateral or Liens are released  pursuant to the applicable  Loan Documents
and pursuant to the terms of the Credit  Agreement.  Each of the Secured Parties
acknowledge  that a release of Collateral  strictly in accordance with the terms
of the Loan  Documents  and of the Credit  Agreement  will not be deemed for any
purpose to be an impairment of the Lien on the  Collateral in  contravention  of
the terms of the Credit Agreement.

                                Power of Attorney

         SECTION  6.01.  Power  of  Attorney.  The  Grantor  irrevocably  makes,
constitutes and appoints the Administrative  Agent (and all officers,  employees
or agents  designated by the  Administrative  Agent) as the  Grantor's  true and
lawful agent and attorney-in-fact, and in such capacity the Administrative Agent
shall have the right,  with power of  substitution  for the  Grantor  and in the
Grantor's name or otherwise, for the use and benefit of the Administrative Agent
and the Secured  Parties,  upon the occurrence and during the  continuance of an
Event of Default  (a) to receive,  endorse,  assign  and/or  deliver any and all
notes,  acceptances,  checks, drafts, money orders or other evidences of payment
relating to the Collateral or any part thereof; (b) to demand, collect,  receive
payment of, give receipt for and give  discharges  and releases of all or any of
the  Collateral;  (c) to sign the name of the  Grantor on any invoice or bill of
lading relating to any of the Collateral;  (d) to commence and prosecute any and
all suits,  actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise  realize on all or any of the Collateral or
to enforce any rights in respect of any Collateral;  (e) to settle,  compromise,
compound,  adjust or defend any actions, suits or proceedings relating to all or
any of the Collateral; (f) to notify, or to require the Grantor to notify, third
parties to make payment  directly to the  Administrative  Agent; and (g) to use,
sell, assign, transfer,  pledge, make any agreement with respect to or otherwise
deal  with all or any of the  Collateral,  and to do all other  acts and  things
necessary to carry out the purposes of this  Agreement,  as fully and completely
as though the Administrative Agent were the absolute owner of the Collateral for
all  purposes;  provided,  however,  that  nothing  herein  contained  shall  be
construed as requiring or  obligating  the  Administrative  Agent or any Secured
Party  to make  any  commitment  or to make  any  inquiry  as to the  nature  or
sufficiency of any payment received by the  Administrative  Agent or any Secured
Party,  or to present or file any claim or  notice,  or to take any action  with
respect to the Collateral or any part thereof or the moneys due or to become due
in respect  thereof or any  property  covered  thereby,  and no action  taken or
omitted  to be  taken by the  Administrative  Agent or any  Secured  Party  with
respect to the  Collateral  or any part thereof  shall give rise to any defense,
counterclaim or offset in favor of the Grantor or to any claim or action against
the Administrative  Agent or any Secured Party. It is understood and agreed that
the appointment of the Administrative Agent as the agent and attorney-in-fact of
the Grantor for the  purposes set forth above is coupled with an interest and is
irrevocable.  The  provisions  of this  Section  shall in no event  relieve  the
Grantor of any of its  obligations  hereunder  or under any other Loan  Document
with respect to the  Collateral or any part thereof or impose any  obligation on
the  Administrative  Agent or any  Secured  Party to proceed  in any  particular
manner with respect to the  Collateral or any part thereof,  or in any way limit
the exercise by the  Administrative  Agent or any Secured  Party of any other or
further  right  which it may have on the date of this  Agreement  or  hereafter,
whether hereunder, under any other Loan Document, by law or otherwise.

                                   ARTICLE VII

                                    Remedies

     SECTION 7.01.  Remedies upon Default.  Upon the  occurrence  and during the
continuance  of an Event of Default,  the Grantor agrees to deliver each item of
Collateral  to the  Administrative  Agent on demand,  and it is agreed  that the
Administrative  Agent shall have the right  (subject to applicable  law) to take
any of or all the following actions at the same or different times: to terminate
any leases of  Collateral,  with or without  legal  process  and with or without
previous notice or demand for performance,  to take possession of the Collateral
and without  liability for trespass to enter any premises  where the  Collateral
may be  located  for  the  purpose  of  taking  possession  of or  removing  the
Collateral and, generally,  to exercise any and all rights afforded to a secured
party  under  the  Uniform  Commercial  Code or other  applicable  law.  Without
limiting  the  generality  of  the  foregoing,   the  Grantor  agrees  that  the
Administrative Agent shall have the right, subject to the mandatory requirements
of  applicable  law,  to sell or  otherwise  dispose  of all or any  part of the
Collateral,  at public or  private  sale,  for cash,  upon  credit or for future
delivery as the Administrative Agent shall deem appropriate. Each such purchaser
at any such sale shall hold the property sold absolutely, free from any claim or
right on the part of the Grantor,  and the Grantor  hereby waives (to the extent
permitted by law) all rights of redemption, stay and appraisal which the Grantor
now has or may at any time in the  future  have under any rule of law or statute
now existing or hereafter enacted.

         The Administrative Agent shall give the Grantor 15 days' written notice
(which the Grantor  agrees is  reasonable  notice  within the meaning of Section
9-504(3) of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions)


<PAGE>


                                                                            11

of the  Administrative  Agent's  intention to make any sale of Collateral.  Such
notice,  in the case of a public  sale,  shall state the time and place for such
sale.  Any such public sale shall be held at such time or times within  ordinary
business hours and at such place or places as the  Administrative  Agent may fix
and state in the notice (if any) of such sale. At any such sale, the Collateral,
or  portion  thereof,  to be sold  may be sold in one lot as an  entirety  or in
separate  parcels,  as the  Administrative  Agent may (in its sole and  absolute
discretion)  determine.  The Administrative Agent shall not be obligated to make
any sale of any Collateral if it shall determine not to do so, regardless of the
fact  that  notice  of  sale of such  Collateral  shall  have  been  given.  The
Administrative  Agent may, without notice or publication,  adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and  place to which the same was so  adjourned.  In case any
sale of all or any  part of the  Collateral  is made  on  credit  or for  future
delivery,  the  Collateral so sold may be retained by the  Administrative  Agent
until the sale price is paid by the  purchaser or  purchasers  thereof,  but the
Administrative Agent shall not incur any liability in case any such purchaser or
purchasers shall fail to take up and pay for the Collateral so sold and, in case
of any such failure,  such Collateral may be sold again upon like notice. At any
public sale made  pursuant  to this  Section,  any Secured  Party may bid for or
purchase,  free (to the extent  permitted by law) from any right of  redemption,
stay,  valuation  or appraisal on the part of the Grantor (all said rights being
also hereby waived and released to the extent  permitted by law), the Collateral
or any part thereof  offered for sale and may make payment on account thereof by
using any claim then due and payable to such Secured Party from the Grantor as a
credit against the purchase  price,  and such Secured Party may, upon compliance
with the terms of sale,  hold,  retain  and  dispose  of such  property  without
further  accountability to the Grantor therefor.  For purposes hereof, a written
agreement to purchase the Collateral or any portion  thereof shall be treated as
a sale thereof;  the  Administrative  Agent shall be free to carry out such sale
pursuant to such  agreement  and the Grantor shall not be entitled to the return
of the Collateral or any portion thereof subject  thereto,  notwithstanding  the
fact  that  after the  Administrative  Agent  shall  have  entered  into such an
agreement  all Events of Default  shall have been  remedied and the  Obligations
paid in full. As an alternative to exercising the power of sale herein conferred
upon it, the  Administrative  Agent may  proceed by a suit or suits at law or in
equity to foreclose  this  Agreement  and to sell the  Collateral or any portion
thereof  pursuant to a judgment or decree of a court or courts having  competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver.

     SECTION 7.02. Application of Proceeds. The Administrative Agent shall apply
the  proceeds  of any  collection  or  sale  of the  Collateral,  as well as any
Collateral consisting of cash, as follows:

                  FIRST,  to the payment of all costs and  expenses  incurred by
         the  Administrative  Agent (in its capacity as such  hereunder or under
         any other Loan Document) in connection  with such collection or sale or
         otherwise in connection with this Agreement or any of the  Obligations,
         including all court costs and the reasonable fees and

                                                                            12

         expenses of its agents and legal counsel, the repayment of all advances
         made by the  Administrative  Agent  hereunder  or under any other  Loan
         Document  on behalf of the  Grantor  and any  other  costs or  expenses
         incurred  in  connection  with the  exercise  of any  right  or  remedy
         hereunder or under any other Loan Document;

                  SECOND, to the payment of the fees and expenses of the Secured
         Parties on an equal and ratable basis;

                  THIRD,  to  the payment of interest on and fees, if any, with 
         respect to the Obligations on an equal and ratable basis;

                  FOURTH,  to  the payment of the unpaid principal amount of the
         Obligations on an equal and ratable basis;

                  FIFTH,  to the payment of costs and  expenses of, all premiums
         on, and all other  amounts due with respect to, the  Obligations  on an
         equal and ratable basis; and

                  SIXTH,  to the Grantor,  its  successors  or assigns,  or as a
         court of competent jurisdiction may otherwise direct.

The  Administrative  Agent  shall  have  absolute  discretion  as to the time of
application  of any such  proceeds,  moneys or balances in accordance  with this
Agreement.  Upon  any  sale  of  the  Collateral  by  the  Administrative  Agent
(including  pursuant  to a power of sale  granted by statute or under a judicial
proceeding),  the receipt of the  Administrative  Agent or of the officer making
the sale shall be a sufficient  discharge to the  purchaser or purchasers of the
Collateral so sold and such  purchaser or  purchasers  shall not be obligated to
see to the  application  of any  part of the  purchase  money  paid  over to the
Administrative  Agent  or  such  officer  or be  answerable  in any  way for the
misapplication thereof.


                                  ARTICLE VIII

                                  Miscellaneous

         SECTION 8.01.  Notices.  All  communications  and   notices  hereunder
shall (except as  otherwise  expressly  permitted  herein)  be  in writing  and
given as provided in Section 10.01 of the Credit Agreement.

         SECTION  8.02.   Security   Interest   Absolute.   All  rights  of  the
Administrative Agent hereunder, the Security Interest and all obligations of the
Grantor  hereunder shall be absolute and  unconditional  irrespective of (a) any
lack of validity or  enforceability  of the Credit  Agreement  or any other Loan
Document,  any  agreement  with respect to any of the  Obligations  or any other
agreement or instrument relating to any of the foregoing, (b) any change in the

                                                                            13

time,  manner or place of payment of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Credit  Agreement,  any other Loan  Document or any other  agreement or
instrument,  (c) any exchange,  release or  non-perfection  of any Lien on other
collateral,  or any  release  or  amendment  or  waiver of or  consent  under or
departure  from  any  guarantee,  securing  or  guaranteeing  all  or any of the
Obligations,  or (d) any other circumstance  which might otherwise  constitute a
defense  available  to,  or a  discharge  of,  the  Grantor  in  respect  of the
Obligations or this Agreement.

         SECTION  8.03.  Survival  of  Agreement.  All  covenants,   agreements,
representations   and  warranties   made  by  the  Grantor  herein  and  in  the
certificates  or other  instruments  prepared or delivered in connection with or
pursuant to this  Agreement or any other Loan  Document  shall be  considered to
have been relied upon by the Secured Parties and shall survive the making by the
Lenders of the Loans, and the execution and delivery to the Lenders of any notes
evidencing such Loans, regardless of any investigation made by the Lenders or on
their behalf,  and shall  continue in full force and effect until this Agreement
shall terminate.

         SECTION 8.04. Binding Effect;  Several Agreement.  This Agreement shall
become effective as to the Grantor when a counterpart  hereof executed on behalf
of the  Grantor  shall have been  delivered  to the  Administrative  Agent and a
counterpart  hereof  shall have been  executed  on behalf of the  Administrative
Agent, and thereafter  shall be binding upon the Grantor and the  Administrative
Agent  and their  respective  successors  and  assigns,  and shall  inure to the
benefit of the Grantor,  the  Administrative  and the other Secured  Parties and
their respective successors and assigns,  except that the Grantor shall not have
the  right to assign  its  rights  hereunder  or any  interest  herein or in the
Collateral  (and any such  assignment  or  transfer  shall  be void)  except  as
expressly contemplated by this Agreement or the Credit Agreement.

         SECTION 8.05. Successors and Assigns. Whenever in this Agreement any of
the parties hereto is referred to, such reference shall be deemed to include the
successors and assigns of such party; and all covenants, promises and agreements
by or on behalf of the Grantor or the Administrative Agent that are contained in
this  Agreement  shall  bind  and  inure  to the  benefit  of  their  respective
successors and assigns.

         SECTION    8.06.    Administrative    Agent's   Fees   and    Expenses;
Indemnification. (a) The Grantor agrees to pay upon demand to the Administrative
Agent the amount of any and all  reasonable  expenses,  including the reasonable
fees,  disbursements  and other  charges of its  counsel  and of any  experts or
agents,  which the  Administrative  Agent may incur in  connection  with (i) the
administration   of  this  Agreement   (including  the  customary  fees  of  the
Administrative  Agent for any ongoing  monitoring or audits conducted by it with
respect to the Collateral), (ii) the custody or preservation of, or the sale of,
collection  from or other  realization  upon any of the  Collateral,  (iii)  the
exercise, enforcement or protection of any of


<PAGE>


                                                                             14

the rights of the  Administrative  Agent  hereunder  or (iv) the  failure of the
Grantor to perform or observe any of the provisions hereof.

         (b) Without  limitation of its  indemnification  obligations  under the
other Loan Documents,  the Grantor agrees to indemnify the Administrative  Agent
and the other Secured Parties  (collectively,  "Indemnitees")  against, and hold
each of them harmless from, any and all losses, claims, damages, liabilities and
related expenses,  including reasonable fees, disbursements and other charges of
counsel,  incurred by or asserted against any of them arising out of, in any way
connected  with, or as a result of, the  execution,  delivery or  performance of
this Agreement or any claim,  litigation,  investigation or proceeding  relating
hereto or to the  Collateral,  whether or not any Indemnitee is a party thereto;
provided that such indemnity  shall not, as to any  Indemnitee,  be available to
the extent that such losses,  claims,  damages,  liabilities or related expenses
are determined by a court of competent  jurisdiction by final and  nonappealable
judgment to have  resulted from the gross  negligence  or willful  misconduct of
such Indemnitee.

         (c) Any such amounts payable as provided  hereunder shall be additional
Obligations  secured  hereby.  The  provisions  of  this  Section  shall  remain
operative  and in full force and effect  regardless of the  termination  of this
Agreement  or any other Loan  Document,  the  consummation  of the  transactions
contemplated  hereby,  the  repayment  of any of the Loans,  the  invalidity  or
unenforceability  of any term or provision  of this  Agreement or any other Loan
Document, or any investigation made by or on behalf of the Administrative Agent,
the Syndication Agent or any Lender. All amounts due under this Section shall be
payable on written demand therefor.

         SECTION 8.07.  GOVERNING LAW. THIS  AGREEMENT  SHALL BE GOVERNED BY THE
LAWS OF THE STATE OF NEW YORK,  EXCLUDING (TO THE EXTENT PERMISSIBLE BY LAW) ANY
RULE OF LAW THAT WOULD  CAUSE THE  APPLICATION  OF THE LAWS OF ANY  JURISDICTION
OTHER THAN THE STATE OF NEW YORK.

         SECTION  8.08.  Waivers;  Amendment.  (a) No  failure  or  delay of the
Collateral  Agent in exercising any power or right  hereunder shall operate as a
waiver  thereof,  nor shall any single or partial  exercise of any such right or
power, or any abandonment or  discontinuance of steps to enforce such a right or
power,  preclude  any other or further  exercise  thereof or the exercise of any
other right or power.  The rights and remedies of the Collateral Agent hereunder
and of the Administrative Agent, the Syndication Agent and the Lenders under the
other Loan  Documents  are  cumulative  and are not  exclusive  of any rights or
remedies  which they would  otherwise  have. No waiver of any provisions of this
Agreement or any other Loan  Document or consent to any departure by the Grantor
therefrom shall in any event be effective  unless the same shall be permitted by
paragraph (b) below,  and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which


<PAGE>


                                                                           15

given.  No notice or demand on the Grantor in any case shall entitle the Grantor
to any other or further notice or demand in similar or other circumstances.

         (b) Neither  this  Agreement  nor any  provision  hereof may be waived,
amended or modified  except  pursuant to an agreement or  agreements  in writing
entered into by the  Administrative  Agent and the Grantor with respect to which
such  waiver,  amendment  or  modification  is to apply,  subject to any consent
required in accordance with Section 10.08 of the Credit Agreement.

         SECTION 8.09. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY  LITIGATION  DIRECTLY  OR  INDIRECTLY  ARISING OUT OF,
UNDER OR IN CONNECTION  WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN  DOCUMENTS.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF  LITIGATION,  SEEK TO ENFORCE THE FOREGOING  WAIVER AND (B)
ACKNOWLEDGES  THAT IT AND THE OTHER  PARTIES  HERETO HAVE BEEN  INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER SECURITY DOCUMENTS,  AS APPLICABLE,  BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION  8.10.  Severability.  In the  event  any  one or  more  of the
provisions  contained in this Agreement or in any other Loan Document  should be
held 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 (it being  understood that
the invalidity of a particular provision in a particular  jurisdiction shall not
in  and  of  itself  affect  the  validity  of  such   provision  in  any  other
jurisdiction).  The parties shall endeavor in good-faith negotiations to replace
the invalid,  illegal or  unenforceable  provisions  with valid  provisions  the
economic  effect of which  comes as close as  possible  to that of the  invalid,
illegal or unenforceable provisions.

         SECTION  8.11.   Counterparts.   This  Agreement  may  be  executed  in
counterparts (and by different parties hereto on different  counterparts),  each
of which shall constitute an original but all of which when taken together shall
constitute a single contract,  and shall become effective as provided in Section
8.04.  Delivery of an executed  signature  page to this  Agreement  by facsimile
transmission  shall be effective as delivery of a manually signed counterpart of
this Agreement.

         SECTION 8.12.  Headings.  Article and Section  headings used herein are
for the  convenience  of reference  only, are not part of this Agreement and are
not to  affect  the  construction  of,  or to be  taken  into  consideration  in
interpreting, this Agreement.

         SECTION  8.13.  Jurisdiction;  Consent to Service of  Process.  (a) The
Grantor  hereby  irrevocably  and  unconditionally  submits,  for itself and its
property,  to the  nonexclusive  jurisdiction  of any New  York  State  court or
Federal court of the United States of America  sitting in New York City, and any
appellate court from any thereof,  in any action or proceeding arising out of or
relating to this Agreement or the other Loan  Documents,  or for  recognition or
enforcement of any judgment,  and each of the parties hereto hereby  irrevocably
and  unconditionally  agrees  that all claims in  respect of any such  action or
proceeding  may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court.  Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other  jurisdictions  by suit on the judgment or in any other manner
provided  by law.  Nothing  in this  Agreement  shall  affect any right that the
Administrative  Agent, the Syndication Agent or any Lender may otherwise have to
bring any action or  proceeding  relating  to this  Agreement  or the other Loan
Documents   against  the  Grantor  or  its  properties  in  the  courts  of  any
jurisdiction.

         (b) The Grantor hereby irrevocably and  unconditionally  waives, to the
fullest extent it may legally and  effectively do so, any objection which it may
now or hereafter  have to the laying of venue of any suit,  action or proceeding
arising out of or relating to this  Agreement or the other Loan Documents in any
New York State or Federal court.  Each of the parties hereto hereby  irrevocably
waives,  to the fullest extent  permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         (c) Each party to this  Agreement  irrevocably  consents  to service of
process by registered  mail,  postage  prepaid.  Nothing in this  Agreement will
affect the right of any party to this  Agreement  to serve  process in any other
manner permitted by law.

         SECTION 8.14.  Termination of Leases.  The Grantor hereby agrees (i) to
take all actions necessary  (including making all required payments) in order to
cause each lease with respect to any real property in or on which  Collateral is
situated  to remain in effect  free and clear of any default or any right of the
applicable  landlord  to  terminate  such lease prior to its  scheduled  date of
maturity and (ii) not to terminate any such lease prior to its scheduled date of
maturity or to modify such lease to shorten such maturity.

                  Subject   to  the   foregoing   and  to  Section   4.05,   the
Administrative Agent agrees to move the  telecommunications  switch (if required
by the lessor of the  property on which the switch is located)  based in Boston,
Massachusetts  and forming part of the  Collateral  if such lease is  terminated
prior to the Term Loan Maturity Date.

         SECTION 8.15. Termination or Release. (a) Except as provided in Section
8.06,  this  Agreement and the Security  Interest  shall  terminate when all the
Obligations  have  been  indefeasibly  paid in  full  and  the  Grantor  and the
Guarantor have no further obligations to the Lenders.

         (b) In connection with any termination pursuant to paragraph (a) above,
upon the request of the Grantor  accompanied  by an  Officers'  Certificate  and
Opinion of Counsel  stating that all conditions  precedent to the termination of
the Lien in the Collateral  pursuant to this Agreement and the Credit  Agreement
have been satisfied,  the Administrative  Agent shall execute and deliver to the
Grantor,  at the Grantor's  expense,  all Uniform  Commercial  Code  termination
statements and similar  documents which the Grantor shall reasonably  request to
evidence such termination.  Any execution and delivery of termination statements
or  documents  pursuant  to this  Section  8.15 shall be without  recourse to or
warranty by the Administrative Agent.


         IN  WITNESS  WHEREOF,  the  parties  hereto  have  duly  executed  this
Agreement as of the day and year first above written.

                    WINSTAR ACCELERATES NATIONWIDE DEPLOYMENT
                          OF SWITCHED BROADBAND NETWORK

             Agrees To Acquire 14 Lucent Class 5 Switches and Other
            Telecommunications Assets of US One Communications Corp.

                   Acquisition Completes 70% of Original 1998
                             Switch Deployment Plan

NEW YORK - OCTOBER 16, 1997, WINSTAR COMMUNICATIONS, INC. (NASDAQ-
WCII) announced today it will significantly accelerate the nationwide deployment
of its  switched  broadband  telecommunications  network  by  acquiring  certain
telecommunications  assets of US One Communications  Corp. The assets include 14
newly-installed  Lucent 5ESS- 2000 switches, as well as a 10-year pre-paid lease
for fiber optic capacity in the New York City  Metropolitan  area.  Through this
transaction,  WinStar will  accomplish 70% of its original  switch  installation
plan for 1998.  The  company  said the  acquisition  will  enable it to  provide
facilities-based  CLEC  services  early next year to  customers in 7 new markets
where US One switches are located:  Minneapolis,  Seattle, Tampa, Denver, Kansas
City, San Francisco, and Columbus, Ohio. This network expansion is six-to-twelve
months ahead of WinStar's original plan.

WinStar  will pay $100  million for the 14 switches  and other  assets.  Of this
amount, $80 million is payable in cash at the time of closing, which is expected
to occur within one week. An additional $20 million will be due in approximately
90-120 days, when there should be a confirmation of U.S. One's  bankruptcy plan.
WinStar has the option of making the final payment in cash or WinStar stock, the
value of which will be set at the time of that payment.  The transaction will be
financed on an interim basis through a new credit facility.  The company expects
this facility will be replaced with long-term equipment financing.

Seven of the  switches  being  acquired  from US One are located in major cities
where WinStar already has installed switch capacity. WinStar has entered into an
agreement to sell two of these duplicate  switches for a total of  approximately
$19  million.  The sale is  expected  to  occur  simultaneously  with  WinStar's
purchase of the US One assets.  WinStar has also received offers to purchase the
remaining  five switches from a variety of parties.  The company is  considering
whether is should retain the incremental capacity represented by the

remaining  five  switches,  and how such  enhanced  switching  capabilities  may
support  the  company's   plans  to  offer  its  broadband   services  to  other
telecommunications firms.

William J. Rouhana,  Jr., WinStar Chairman,  and Chief Executive  Officer,  said
today the US One  transaction  represented  a unique  opportunity  to  virtually
double WinStar's local and long distance network on a much faster timetable than
originally  planned. He noted that WinStar's number of switched cities will grow
from 8 to 15 in the next few months as a result of this transaction, and pointed
out that WinStar's 38 GHz spectrum  holdings average greater than 500 MHz in the
new markets that will be served by the retained switches.

Rouhana also stated that the price paid for the switches is less than what would
have been  spent to create  the same  amount  of  switch  capacity  in the seven
cities, when all related costs are considered.  He went on to say "It is a great
advantage  to be able to sell  switched  services in new markets  where we would
typically  have  started  out as a  reseller  of lines  belonging  to the  local
exchange carrier. We will now be able to bring local traffic onto our own switch
from the outset, thereby reducing the EBITDA losses that generally accompany our
entry into new cities."

           WINSTAR COMPLETES ACQUISITION OF 14 LUCENT CLASS 5 SWITCHES
                  AND OTHER TELECOMMUNICATIONS ASSETS OF US ONE

NEW YORK -  OCTOBER  20,  1997,  WINSTAR  COMMUNICATIONS,  INC.  (NASDAQ-  WCII)
announced today it has completed the acquisition of 14 Lucent 5ESS-2000 switches
and other  telecommunications  assets  of US One  Communications  Corp.  WinStar
announced  on  October  16,  1997 its  plans to  purchase  the  switches  and to
accelerate the deployment of its broadband telecommunications network.

WinStar paid $100 million for the acquisition,  $80 million of which was paid in
cash at the closing. A final payment of $20 million, which WinStar can choose to
make in the form of cash or WinStar stock, will be made in approximately  90-120
days, when US One's bankruptcy plan receives final court approval. In a separate
transaction,  the company has also  received  approximately  $19 million in cash
from the sale of two of the former US One  switches  which  duplicated  capacity
already in place.  WinStar  said today it is  discussing  purchase  offers  from
various parties for five other switches.

WinStar received a credit facility from Salomon Brothers and Credit Suisse First
Boston to finance the  transaction on an interim basis.  The company  expects to
replace this facility with long-term equipment financing.
