ITEM 5.  OTHER EVENTS.

ACE/USAM MERGER

        On June 29, 1998, Arch Communications  Group, Inc. ("Parent") effected a
number  of  restructuring  transactions  involving  certain  of its  direct  and
indirect  wholly-owned  subsidiaries.   Arch  Communications  Enterprises,  Inc.
("ACE")   was  merged  (the   "Merger")   into  a   subsidiary   of  USA  Mobile
Communications,  Inc. II ("USAM") named Arch Paging, Inc. ("API"). In connection
with the Merger, USAM changed its name to Arch Communications,  Inc. ("ACI") and
issued  100 shares of its common  stock to Parent.  Immediately  prior to and in
connection  with the  Merger:  (i) USAM  contributed  its  operating  assets and
liabilities to an existing subsidiary of USAM; (ii) The Westlink Company,  which
held ACE's  49.9%  equity  interest  in Benbow PCS  Ventures,  Inc.  ("Benbow"),
distributed  its Benbow assets and  liabilities  to a new subsidiary of ACE, The
Westlink  Company II; (iii) ACE contributed its operating assets and liabilities
to an existing  subsidiary of ACE; (iv) all of USAM's  subsidiaries  were merged
into API; and (v) The Westlink  Company II was merged into a new API subsidiary,
Benbow Investments, Inc.

AMENDED CREDIT FACILITY

        Contemporaneously  with the Merger,  ACE's existing  credit facility was
amended and restated to establish senior secured  revolving credit and term loan
facilities with API, as borrower,  and The Bank of New York (the "Bank"),  Royal
Bank of Canada and Toronto Dominion  (Texas),  Inc., as managing agents,  in the
aggregate amount of $400.0 million (collectively, the "Amended Credit Facility")
consisting  of (i) a $175.0  million  reducing  revolving  credit  facility (the
"Tranche A Facility"),  (ii) a $100.0 million 364-day  revolving credit facility
under which the  principal  amount  outstanding  on the 364th day  following the
closing  will  convert  to a term loan (the  "Tranche B  Facility")  and (iii) a
$125.0  million term loan which was available in a single drawing on the closing
date (the "Tranche C Facility").

        The Tranche A Facility will be subject to scheduled quarterly reductions
commencing on September 30, 2000 and will mature on June 30, 2005. The term loan
portion of the Tranche B Facility  will be amortized  in quarterly  installments
commencing  September 30, 2000, with an ultimate maturity date of June 30, 2005.
The  Tranche C Facility  will be  amortized  in annual  installments  commencing
December 31, 1999, with an ultimate maturity date of June 30, 2006.

        API's  obligations  under the Amended Credit Facility are secured by its
pledge of the  capital  stock of the  former  ACE  operating  subsidiaries.  The
Amended  Credit  Facility  is  guaranteed  by  Parent,  ACI and the  former  ACE
operating  subsidiaries.  Parent's  guarantee is secured by a pledge of Parent's
stock  and  notes  in ACI,  and  the  guarantees  of the  former  ACE  operating
subsidiaries  are  secured  by a  security  interest  in  those  assets  of such
subsidiaries  which were pledged under ACE's previous credit  facility.  Lenders
representing  40% of the Amended  Credit  Facility have the right to require ACI
and its subsidiaries to grant security  interests in certain  additional  assets
not  currently  pledged  thereunder,  subject  to  granting  a ratable  security

<PAGE>

interest to holders of ACI's $125.0  million  principal  amount of 9 1/2% Senior
Notes due 2004 and ACI's $100.0 million principal amount of 14% Senior Notes due
2004.

        Borrowings  under the Amended  Credit  Facility bear interest based on a
reference rate equal to either the Bank's  Alternate Base Rate or LIBOR rate, in
each  case  plus a  margin  based on  ACI's  or  API's  ratio  of total  debt to
annualized operating cash flow.

        The  Amended  Credit  Facility  requires  payment  of fees on the  daily
average  amount  available  to be borrowed  under the Tranche A Facility and the
Tranche B Facility,  which fees vary  depending on ACI's or API's ratio of total
debt to annualized operating cash flow.

        The Amended Credit  Facility  contains  restrictions  that limit,  among
other things: additional indebtedness and encumbrances on assets; cash dividends
and  other  distributions;  mergers  and  sales of  assets;  the  repurchase  or
redemption  of capital  stock;  investments;  acquisitions  that exceed  certain
dollar  limitations  without the lenders'  prior  approval;  and  prepayment  of
indebtedness  other than  indebtedness  under the Amended  Credit  Facility.  In
addition,  the Amended Credit Facility requires ACI and its subsidiaries to meet
certain  financial  covenants,  including  covenants  with  respect to ratios of
operating  cash flow to fixed  charges,  operating  cash  flow to debt  service,
operating cash flow to interest service and total indebtedness to operating cash
flow.

ISSUANCE AND SALE OF NOTES

        Contemporaneously  with the Merger,  ACI issued and sold $130.0  million
principal amount of 12 3/4% Senior Notes due 2007 (the "Notes") to Bear, Stearns
& Co., Inc.,  Barclays Capital Inc., RBC Dominion  Securities  Corporation,  BNY
Capital Markets,  Inc. and TD Securities  (USA) Inc. (the "Initial  Purchasers")
for net proceeds of $122.6 million (after  deducting the discount to the Initial
Purchasers  and  estimated  offering  expenses  payable  by  ACI)  in a  private
placement  (the "Note  Offering")  under Rule 144A under the  Securities  Act of
1933.  The Notes were sold at an initial  price to  investors  of  98.049%.  The
proceeds of the Note  Offering  were  applied as  described  below under "Use of
Proceeds". The terms of the Notes are summarized below:

  MATURITY

        July 1, 2007.

  INTEREST

        The  Notes  bear  interest  at a rate  of 12  3/4%  per  annum,  payable
semi-annually  in  arrears  on  January  1 and July 1 of each  year,  commencing
January 1, 1999.

<PAGE>

RANKING

        The Notes are senior unsecured obligations of ACI and rank pari passu in
right of payment with other existing and future senior  indebtedness of ACI. ACI
is an intermediate  holding company of Parent with no material assets other than
the stock of its  subsidiaries.  The Notes are structurally  subordinated to all
current or future  liabilities of ACI's  subsidiaries,  including trade payables
and indebtedness. At June 30, 1998, after giving effect to the Note Offering and
application  of the  estimated net proceeds  therefrom as described  below under
"Use of Proceeds",  borrowings  pursuant to the Amended Credit  Facility and the
Equity  Investment  (as  defined  below)  and the  application  of the  proceeds
therefrom,  the Notes were  structurally  subordinated to  approximately  $343.2
million of liabilities of ACI's subsidiaries.  In addition, Parent does not have
any  obligation  to pay any amounts due with respect to the Notes or to make any
funds available  therefor.  At June 30, 1998,  Parent had  approximately  $364.0
million of liabilities  (excluding  liabilities of its subsidiaries and Parent's
guarantees thereof).

  OPTIONAL REDEMPTION

        Except  as set forth  below,  the Notes  will not be  redeemable  at the
option of ACI prior to July 1,  2003.  Thereafter,  the Notes will be subject to
redemption at the option of ACI, in whole or in part, at the  redemption  prices
set forth herein plus accrued and unpaid  interest  and  Liquidated  Damages (as
defined below), if any, to the applicable  redemption date.  Notwithstanding the
foregoing,  at any time prior to July 1,  2001,  ACI may redeem up to 35% of the
Notes at a redemption  price of 112 3/4% of the principal  amount thereof,  plus
accrued and unpaid  interest and Liquidated  Damages,  if any, to the redemption
date,  with the net  cash  proceeds  of an  equity  offering  for cash by ACI or
Parent;  provided that at least $84.5 million aggregate  principal amount of the
Notes  originally  issued under the  indenture  pursuant to which the Notes were
issued (the "Indenture") remain outstanding  immediately after the occurrence of
each such  redemption;  and provided  further,  that such redemption shall occur
within  75 days  following  the date of the  consummation  of each  such  equity
offering.

  CHANGE OF CONTROL

        Upon the occurrence of a Change of Control (as defined in the Indenture)
at any time, ACI will be obligated to make an offer to repurchase  each Holder's
Notes at a price equal to 101% of the aggregate  principal amount thereof,  plus
accrued  and unpaid  interest  and  Liquidated  Damages,  if any, to the date of
purchase.

  CERTAIN COVENANTS

        The Indenture contains certain covenants that, among other things, limit
the ability of ACI to incur additional indebtedness,  issue preferred stock, pay
dividends or make other  distributions,  repurchase Capital Stock (as defined in
the  Indenture),  repay  subordinated  indebtedness  or  make  other  Restricted
Payments (as defined in the Indenture), create certain liens, enter into certain
transactions with affiliates,  sell assets, issue or sell Capital Stock of ACI's

<PAGE>

Restricted  Subsidiaries  (as defined in the  Indenture)  or enter into  certain
mergers and consolidations.

  USE OF PROCEEDS

        ACI used the net proceeds of the Note Offering, together with borrowings
under the Amended Credit Facility and the Equity Investment,  to repay a portion
of the  indebtedness  under ACE's previous  credit  facility and all outstanding
indebtedness  under USAM's  previous credit  facility.  Amounts not repaid under
ACE's  previous  credit  facility  became  outstanding  under the Amended Credit
Facility.

  EXCHANGE OFFER; REGISTRATION RIGHTS

        Pursuant to an Exchange and Registration  Rights Agreement among ACI and
the  Initial  Purchasers,  ACI  agreed  to file a  registration  statement  (the
"Exchange Offer  Registration  Statement")  with respect to an offer to exchange
the Notes (the "Exchange  Offer") for new notes of ACI (the  "Exchange  Notes").
The Exchange  Notes will be issued under the Indenture as a separate  series but
with terms  identical  to the Notes.  ACI is required  to (i) file the  Exchange
Offer  Registration  Statement on or prior to July 29,  1998,  (ii) use its best
efforts to have the Exchange Offer  Registration  Statement  declared  effective
prior to October 27, 1998 and (iii) commence the Exchange Offer and use its best
efforts to issue,  on or prior to 30  business  days after the date on which the
Exchange Offer Registration  Statement is declared effective,  Exchange Notes in
exchange for all Notes tendered prior thereto in the Exchange  Offer. If (i) the
Exchange Offer is not permitted by applicable law or (ii) any Holder of Transfer
Restricted  Securities (as defined in the Indenture) notifies ACI that (a) it is
prohibited  by  law  or   Securities   and  Exchange   Commission   policy  from
participating  in the  Exchange  Offer,  (b) it may not resell an Exchange  Note
acquired  by it in  the  Exchange  Offer  to the  public  without  delivering  a
prospectus and that the prospectus  contained in the Exchange Offer Registration
Statement  is not  appropriate  or  available  for  such  resale  or (c) it is a
broker-dealer and holds Notes acquired directly from ACI or an affiliate of ACI,
ACI  will be  required  to  file a  shelf  registration  statement  (the  "Shelf
Registration  Statement") to cover resales of the Notes by the Holders  thereof.
If ACI fails to satisfy these  registration  obligations,  it is required to pay
liquidated damages  ("Liquidated  Damages") to each holder of Notes of up to 100
basis points per annum of the principal amount of Notes held by such holder. ACI
expects to file the Exchange  Offer  Registration  Statement on or prior to July
29, 1998.

EQUITY INVESTMENT

        On June 29, 1998, two partnerships managed by Sandler Capital Management
Company, Inc., an investment management firm ("Sandler"),  together with certain
other private investors, made an equity investment in Parent of $25.0 million in
the form of Series C Convertible  Preferred Stock of Parent ("Series C Preferred
Stock"). Simultaneously,  Parent contributed to ACI as an equity investment (the
"Equity Investment") $24.0 million of the net proceeds from the sale of Series C
Preferred Stock, ACI contributed such amount to API as an equity  investment and

<PAGE>

API used such amount to repay  indebtedness under ACE's existing credit facility
as part of the establishment of the Amended Credit Facility.

        The Series C Preferred  Stock:  (i) is convertible  into Common Stock of
Parent at an initial  conversion  price of $5.50 per  share,  subject to certain
adjustments;  (ii)  bears  dividends  at an  annual  rate of 8.0%,  (A)  payable
quarterly  in cash or, at Parent's  option,  through  the  issuance of shares of
Parent's Common Stock valued at 95% of the then  prevailing  market price or (B)
if not paid quarterly, accumulating and payable upon redemption or conversion of
the Series C Preferred Stock or liquidation of Parent; (iii) permits the holders
after seven years to require Parent,  at Parent's option, to redeem the Series C
Preferred  Stock for cash or convert  such shares  into  Parent's  Common  Stock
valued at 95% of the then prevailing market price of Parent's Common Stock; (iv)
is subject to redemption  for cash or conversion  into Parent's  Common Stock at
ACI's option in certain circumstances; (v) in the event of a "Change of Control"
as defined in the Indenture governing Parent's 10 7/8% Senior Discount Notes due
2008 (the "Parent Discount Notes Indenture"), requires Parent, at its option, to
redeem  the  Series C  Preferred  Stock for cash or  convert  such  shares  into
Parent's  Common  Stock  valued at 95% of the then  prevailing  market  price of
Parent's Common Stock,  with such cash redemption or conversion being at a price
equal  to  105% of the  sum of the  original  purchase  price  plus  accumulated
dividends;  (vi) limits certain mergers or asset sales by Parent;  (vii) so long
as at least 50% of the Series C Preferred Stock remains outstanding,  limits the
incurrence  of  indebtedness  and  "restricted  payments"  in the same manner as
contained in the Parent Discount Notes Indenture;  and (viii) has certain voting
and preemptive rights. The holders of the Series C Preferred Stock also received
customary registration and information rights.

        So  long  as at  least  50% of the  Series  C  Preferred  Stock  remains
outstanding,  the holders of the Series C Preferred Stock have the right, voting
as a separate  class,  to  designate  one member of the Boards of  Directors  of
Parent and ACI, and such  director has the right to be a member of any committee
of such Boards of  Directors.  Upon the closing of the Series C Preferred  Stock
financing,  John  Kornreich,  a Managing  Director  of  Sandler,  was  elected a
director of Parent and ACI pursuant to these arrangements.

        Immediately   prior  to  the  Series  C   Preferred   Stock   financing,
partnerships managed by Sandler owned 4.1% of Parent's outstanding Common Stock.
After giving effect to the issuance of the Series C Preferred Stock, the holders
of the Series C Preferred Stock  beneficially  owned (including the Common Stock
owned by partnerships  managed by Sandler) 21.2% of Parent's  Common Stock.  The
investors  in  the  Series  C  Preferred  Stock  financing   agreed  to  certain
"standstill"  provisions limiting their beneficial ownership in Parent to 24.99%
(provided  that the receipt of Parent's  Common Stock in payment of dividends on
the Series C Preferred Stock does not constitute a breach of this limitation).

TOWER SITE SALE

        In April 1998,  Parent  announced  an agreement to sell certain of ACI's
tower site assets (the "Tower Site Sale") for  approximately $38 million in cash
(subject to  adjustment),  of which $1.3 million will be paid to a subsidiary of

<PAGE>

Benbow in payment for certain  assets owned by such  subsidiary  and included in
the Tower Site  Sale.  In the Tower  Site  Sale,  ACI is selling  communications
towers,  real estate,  site  management  contracts  and/or  leasehold  interests
involving  134 sites in 22 states and leasing  back space on the towers on which
it  currently  operates  communications  equipment  to  service  its own  paging
network. ACI will use its net proceeds from the Tower Site Sale (estimated to be
$36  million) to repay  indebtedness  under the  Amended  Credit  Facility.  The
agreement for the Tower Site Sale calls for an initial closing to be followed 60
days later by a final  closing.  ACI held the initial  closing of the Tower Site
Sale on June 26, 1998 with gross  proceeds to ACI of  approximately  $12 million
and  currently  expects  to  hold  the  final  closing  for the  balance  of the
transaction  in the third  quarter of 1998,  although no assurance  can be given
that the final closing will be held as expected.

DIVISIONAL REORGANIZATION

        In June 1998,  Parent's Board of Directors  approved a reorganization of
Parent's operations (the "Divisional Reorganization"). As part of the Divisional
Reorganization,  which  will be  implemented  over a period of 18 to 24  months,
Parent plans to consolidate  its seven  operating  divisions into four operating
divisions,  and consolidate certain regional  administrative  support functions,
resulting in various operating  efficiencies.  ACI estimates that the Divisional
Reorganization,  once fully  implemented,  will result in annual cost savings of
approximately $15 million  (approximately  $11.5 million for salary and employee
benefits  and $3.5  million  for lease  obligations).  ACI expects to reinvest a
portion of these cost savings to expand its sales activities. In connection with
the  Divisional  Reorganization,  Parent  (i)  anticipates  a net  reduction  of
approximately 10% of its workforce, (ii) plans to close certain office locations
and  redeploy   other  real  estate   assets  and  (iii)  expects  to  record  a
restructuring  charge of approximately $15 million to $25 million for the second
quarter  of  1998.   The   restructuring   charge  is  expected  to  consist  of
approximately  (i) $8 million  for  employee  severance  and  benefits,  (ii) $4
million to $9 million for lease obligations and terminations, (iii) $1.5 million
to $5 million  for the  writedown  of fixed  assets and (iv) $1.5  million to $3
million for other items.

PAGE CALL ACQUISITION

        Prior  to June  29,  1998,  Benbow  held  exclusive  rights  to a 50 KHz
outbound/12.5 KHz inbound narrowband personal communications services ("N- PCS")
license in each of the  Central and Western  regions of the United  States,  and
Page Call, Inc. ("Page Call") owned exclusive  rights to a 50 KHz  outbound/12.5
KHz inbound N-PCS license in each of the Northeast, South and Midwest regions of
the United States, utilizing the same radio frequency as Benbow's existing N-PCS
licenses.  On June 29, 1998, Benbow acquired Page Call's outstanding stock. As a
result of the Page Call  acquisition,  Benbow  holds  (directly  or through Page
Call) licenses  covering all five regions of the United States.  Benbow needs to
construct  its N-PCS  system  (or make other  arrangements)  before it can offer
N-PCS services.

        Benbow acquired Page Call's  outstanding stock by issuing to Page Call's
former stockholders  preferred stock and a promissory note in the aggregate face
amount of $17.2  million  with a 12% annual  return.  Upon the  closing,  Benbow
entered  into  a  five-year   consulting  agreement  with  one  of  Page  Call's

<PAGE>

stockholders  requiring consulting payments in the aggregate amount of $911,000.
Benbow's  preferred stock and promissory note are  exchangeable for Common Stock
of Parent (i) at any time at the option of the holders  thereof,  at an exchange
price  equal to the higher of (A)  $13.00  per share or (B) the market  price of
Parent's Common Stock, (ii) mandatorily on April 8, 2000, at the then prevailing
market price of Parent's  Common Stock,  or (iii)  automatically  at an exchange
price of $13.00 per share,  if the market price of Parent's  Common Stock equals
or exceeds  $13.00 for 20  consecutive  trading  days.  Parent is  permitted  to
require Benbow to redeem its preferred stock and promissory note at any time for
cash. Parent entered into guarantees  (payable in Parent's Common Stock or cash,
at Parent's  election) of all  obligations of Benbow under the Benbow  preferred
stock,  promissory  note and  consulting  agreement  described  above.  Benbow's
redemption  of its  preferred  stock and  promissory  note for cash, or Parent's
payment of cash  pursuant  to its  guarantees  of Benbow's  preferred  stock and
promissory  note,  would be  subject  to the  availability  of  capital  and any
restrictions  contained in applicable debt  instruments and under applicable law
(which  currently  would not permit any such cash  redemptions or payments).  If
Parent issues Common Stock or pays cash pursuant to its guarantees,  Parent will
receive from Benbow a promissory note and non-voting,  non-convertible preferred
stock of Benbow with an annual  yield of 14.5%  payable upon an  acquisition  of
Benbow or earlier to the extent that  available  cash and applicable law permit.
Page Call's stockholders received customary  registration rights with respect to
any shares of Parent's  Common Stock  issued in exchange for Benbow's  preferred
stock and promissory note or pursuant to Parent's guarantees thereof.

condition or covenant provided for in this Indenture shall include:

SECTION I.3 FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

covered by an opinion of, any specified  Person,  it is not  necessary  that all
such  matters  be  certified  by, or covered by the  opinion  of,  only one such
Person,  or that they be so certified or covered by only one  document,  but one
such Person may certify or give an opinion  with respect to some matters and one
or more other such Persons as to other matters,  and any such Person may certify
or give an opinion as to such matters in one or several documents.

Counsel, unless such officer knows, or in the exercise of reasonable care should
know,  that the  certificate or opinion or  representations  with respect to the
matters upon which his  certificate or opinion is based are erroneous.  Any such
certificate or Opinion of Counsel may be based, insofar as it relates to factual
matters,  upon a certificate or opinion of, or representations by, an officer or
officers  of the  Company  stating  that the  information  with  respect to such
factual  matters is in the possession of the Company,  unless such counsel knows
that the certificate or opinion or representations  with respect to such matters
are erroneous.

applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

SECTION I.4    ACTS OF HOLDERS; RECORD DATES.

          (1) Any request, demand,  authorization,  direction,  notice, consent,
waiver  or  other  action  provided  by this  Indenture  to be given or taken by
Holders  may  be  embodied  in and  evidenced  by one  or  more  instruments  of
substantially  similar  tenor  signed by such Holders in person or by agent duly
appointed in writing;  and, except as herein otherwise expressly provided,  such
action shall become  effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required,  to the Company. Such
instrument  or  instruments  (and the  action  embodied  therein  and  evidenced
thereby) are herein  sometimes  referred to as the "Act" of the Holders  signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing  appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section  6.01)  conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

          (2) The fact  and  date of the  execution  by any  Person  of any such
instrument  or  writing  may be proved  by the  affidavit  of a witness  of such
execution or by a certificate of a notary public or other officer  authorized by
law to take  acknowledgments  of deeds,  certifying that the individual  signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution  is by a  signer  acting  in a  capacity  other  than  his  individual
capacity,  such certificate or affidavit shall also constitute  sufficient proof

                                       16
<PAGE>

of his authority.  The fact and date of the execution of any such  instrument or
writing,  or the authority of the Person  executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

          (3) The Company or the Trustee may, in the circumstances  permitted by
the Trust  Indenture  Act,  fix any day as the  record  date for the  purpose of
determining  the  Holders  entitled  to  give  or  take  any  request,   demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action,  authorized  or permitted  to be given or taken by Holders,  and the
Company agrees to notify the Trustee of any such fixing of a record date. If not
set by the Company or the Trustee  prior to the first  solicitation  of a Holder
made by any Person in respect  of any such  action,  or, in the case of any such
vote,  prior to such vote,  the record date for any such action or vote shall be
the 30th day (or, if later, the date of the most recent list of Holders required
to be provided  pursuant to Section  7.01) prior to such first  solicitation  or
vote,  as the case may be. With regard to any record  date,  only the Holders on
such date (or their duly designated  proxies) shall be entitled to give or take,
or vote on, the relevant action.

          (4) The  ownership  of  Securities  shall be  proved  by the  Security
Register.

          (5) Any request, demand,  authorization,  direction,  notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the  same  Security  and  the  Holder  of  every  Security  issued  upon  the
registration of transfer thereof or in exchange  therefore or in lieu thereof in
respect of anything  done,  omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

SECTION I.5 NOTICES, ETC., TO TRUSTEE AND COMPANY.

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other  document  provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

          (1) the  Trustee by any Holder or by the Company  shall be  sufficient
for every purpose hereunder if made, given,  furnished or filed in writing to or
with the Trustee at its  Corporate  Trust  Office,  Attention:  Corporate  Trust
Administration, or

          (2) the  Company by the Trustee or by any Holder  shall be  sufficient
for every purpose hereunder  (unless otherwise herein expressly  provided) if in
writing and mailed,  first-class postage prepaid, to the Company addressed to it
at the address of its principal  office specified in the first paragraph of this
instrument  or at any other  address  previously  furnished  in  writing  to the
Trustee by the Company.

SECTION I.6 NOTICE TO HOLDERS; WAIVER.

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly  provided)
if in writing and mailed,  first-class  postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register,  not later
than the latest date (if any),  and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is

                                       17
<PAGE>

given by mail,  neither the failure to mail such  notice,  nor any defect in any
notice so mailed,  to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture  provides for notice
in any manner,  such  notice may be waived in writing by the Person  entitled to
receive such notice, either before or after the event, and such waiver, shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee,  but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

          In case by reason of the  suspension  of  regular  mail  service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such  notification  as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION I.7    CONFLICT WITH TRUST INDENTURE ACT.

          If  any  provision  hereof  limits,  qualifies  or  conflicts  with  a
provision  of the Trust  Indenture  Act that is required  under such Act to be a
part of and govern this Indenture,  the latter  provision shall control.  If any
provision  of this  Indenture  modifies or excludes  any  provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded,  as the case
may be.

          Nothing in this  Indenture or in the  Securities,  express or implied,
shall give to any  Person,  other than the parties  hereto and their  successors
hereunder and the Holders of  Securities,  any benefit or any legal or equitable
right, remedy or claim under this Indenture.

SECTION I.12   GOVERNING LAW; JURISDICTION.

          This Indenture and the  Securities  shall be governed by and construed
in  accordance  with the laws of the  State of New York,  without  regard to the

                                       18
<PAGE>

conflicts  of laws  principles  thereof.  If any action or  proceeding  shall be
brought  by the  Trustee  or by a Holder  of any of the  Securities  in order to
enforce any right or remedy under this  Indenture or under the  Securities,  the
Company  hereby  consents and submits to the  jurisdiction  of the courts of the
State of New York and of any  Federal  court  sitting  in The City of New  York,
State of New York.  Any action or  proceeding  brought by the Company to enforce
any right,  assert any claim or obtain any relief  whatsoever in connection with
this Indenture or the Securities shall be brought by the Company  exclusively in
the courts of the State of New York or in any Federal  court sitting in The City
of New York, State of New York.

SECTION I.13 LEGAL HOLIDAYS.

        In any case where any Interest Payment Date,  Redemption Date,  Purchase
Date or Stated  Maturity  of any  Security  shall not be a  Business  Day,  then
(notwithstanding  any other  provision of this  Indenture or of the  Securities)
payment of interest or principal (and premium,  if any) need not be made on such
date,  but may be made on the next  succeeding  Business Day with the same force
and effect as if made on the Interest Payment Date,  Redemption  Date,  Purchase
Date or at the Stated  Maturity,  provided that no interest shall accrue for the

<PAGE>


          (a) Transfer and Exchange of Definitive  Securities.  When  Definitive
Securities  are  presented  by a Holder to the  Registrar  with a request (1) to
register  the  transfer of the  Definitive  Securities  or (2) to exchange  such
Definitive  Securities for an equal principal amount of Definitive Securities of
other  authorized  denominations,  the Registrar  shall register the transfer or
make the exchange as requested if its  requirements  for such  transactions  are
met;  provided  that any  Definitive  Securities  presented or  surrendered  for
registration  of transfer or exchange (A) shall be duly endorsed or  accompanied
by a written  instruction of transfer in form satisfactory to the Registrar duly
executed by the Holder  thereof or by his attorney  duly  authorized in writing;
(B)  unless the Global  Security  has  previously  been  exchanged  in whole for
Definitive  Securities,  shall only be  exchanged  for an interest in the Global
Security in accordance with Section  2.04(b) if such  Definitive  Securities are
being transferred (i) pursuant to an effective  registration statement under the
Securities  Act;  (ii) to a QIB in reliance on Rule 144A;  or (iii)  outside the
United  States to a non-U.S.  person in reliance on Regulation S; and (C) in the
case of a Transfer Restricted Security, such request shall be accompanied by the
following  additional  documents:  (i) if such Transfer  Restricted  Security is
being  delivered to the  Registrar by a Holder for  registration  in the name of
such Holder,  without transfer, a certification to that effect (in substantially
the form of  Exhibit B attached  hereto);  or (ii) if such  Transfer  Restricted
Security is being  transferred  to an IAI in reliance on an  exemption  from the
registration requirements of the Securities Act, other than to a QIB in reliance
on Rule 144A or outside  the United  States to a non-U.S.  person in reliance on
Regulation  S, a  certification  to that  effect (in  substantially  the form of
Exhibit B attached hereto), and a letter containing certain  representations and
agreements  (in  substantially  the form of Exhibit C attached  hereto)  and, if
requested  by the  Company  or the  Trustee,  an  opinion  of  counsel in a form
acceptable to the Company and the Trustee to the effect that such transfer is in
compliance with the Securities Act.

          (b) Transfer of a Definitive Security for a Beneficial Interest in the
Global  Security.  A  Definitive  Security  may be  exchanged  for a  beneficial
interest in the Global Security only upon receipt by the Trustee of a Definitive
Security,  duly endorsed or accompanied by appropriate  instruments of transfer,
in form  satisfactory  to the Trustee,  together with: (i) written  instructions
directing the Trustee to make an endorsement  on the Global  Security to reflect
an increase in the aggregate  principal amount of the Securities  represented by
the  Global  Security,  and  (ii)  if such  Definitive  Security  is a  Transfer
Restricted  Security,  a certification  (in  substantially the form of Exhibit B
attached  hereto) to the effect that such  Definitive  Security is either  being
transferred  to a QIB in reliance on Rule 144A or outside the United States to a
non-U.S.  person in reliance on  Regulation  S; in which case the Trustee  shall
cancel such  Definitive  Security and cause the  aggregate  principal  amount of
Securities represented by the Global Security to be increased accordingly. If no
Global  Security is then  outstanding,  the Company  shall issue and the Trustee
shall authenticate a new Global Security in the appropriate principal amount.

          (c)  Transfer  of a  Beneficial  Interest in a Global  Security  for a
Definitive  Security.  A  beneficial  interest  in the  Global  Security  may be
exchanged for a Definitive  Security  only in the case of a Transfer  Restricted
Security,  and upon receipt by the Trustee of written transfer  instructions (or
such other form of  instructions  as is customary for the  Depositary)  from the
Depositary (or its nominee) on behalf of any Person having a beneficial interest
in a Global Security that such Transfer Restricted Security is being transferred
to an IAI in reliance on an exemption from the registration  requirements of the
Securities  Act,  other than to a QIB in  reliance  on Rule 144A or outside  the
United States to a non-U.S. person in reliance on Regulation S, provided however

                                       22
<PAGE>

that  such  request  is  accompanied  by a  certification  to  that  effect  (in
substantially  the form of Exhibit B attached  hereto)  and a letter  containing
certain  representations  and agreements (in substantially the form of Exhibit C
attached hereto) and, if requested by the Company or the Trustee,  an opinion of
counsel in a form  reasonably  acceptable  to the Company and the Trustee to the
effect that such transfer is in  compliance  with the  Securities  Act, in which
case the  Trustee  shall,  in  accordance  with the  standing  instructions  and
procedures existing between the Depositary and the Trustee,  cause the aggregate
principal amount of the Global Security to be reduced accordingly and, following
such reduction, the Company shall execute and the Trustee shall authenticate and
make  available  for delivery to the  transferee  a  Definitive  Security in the
appropriate principal amount.

          Definitive  Securities issued in exchange for a beneficial interest in
a Global  Security  shall be  registered  in such  names and in such  authorized
denominations as the Depositary shall instruct the Trustee.

          (d)  Transfer  and  Exchange  of  Beneficial  Interests  in the Global
Security.  The  transfer  and  exchange of  beneficial  interests  in the Global
Security  shall be  effected  through the  Depositary  in  accordance  with this
Indenture and the  procedures of the  Depositary  therefor,  which shall include
restrictions  on  transfer  comparable  to those set forth  herein to the extent
required by the Securities Act.

          When a Global  Security is presented to the  Registrar  with a request
(1) to  register  the  transfer of the Global  Security or (2) to exchange  such
Global  Securities  for  an  equal  principal  amount  of  Securities  of  other
denominations, the Registrar shall register the transfer or make the exchange if
its requirements  for such  transactions are met;  provided,  however,  that any
Security  presented or surrendered for  registration of transfer or exchange (A)
shall be duly endorsed or  accompanied  by a written  instruction of transfer in
form  satisfactory  to the Registrar and the Trustee duly executed by the Holder
thereof or by his attorney  duly  authorized in writing and (B) in the case of a
Transfer Restricted Security, such request shall be accompanied by the following
additional  documents:  (i)  if  such  Transfer  Restricted  Security  is  being
transferred  to the Person  designated by the Depositary as being the beneficial
owner, a certification  to that effect (in  substantially  the form of Exhibit B
attached hereto), (ii) if such Transfer Restricted Security is being transferred
to a QIB in accordance  with Rule 144A or pursuant to an effective  registration
statement  under  the  Securities  Act,  a  certification  to  that  effect  (in
substantially the form of Exhibit B attached hereto),  or (iii) if such Transfer
Restricted  Security is being  transferred in reliance on another exemption from
the  registration  requirements of the Securities  Act, a certification  to that
effect  (in  substantially  the form of  Exhibit  B  attached  hereto)  and,  if
requested  by the  Company  or the  Trustee,  an  opinion  of  counsel in a form
reasonably  acceptable to the Company and to the Trustee to the effect that such

transfer  and  exchanges,   the  Company  shall  issue  and  the  Trustee  shall
authenticate Securities at the Registrar's request, subject to such rules as the
Trustee may reasonably require.

          (e) Cancellation  and/or  Adjustment of the Global  Security.  At such
time as all  beneficial  interests  in the  Global  Security  have  either  been
exchanged for Definitive  Securities,  redeemed,  repurchased  or canceled,  the
Global Security shall be returned to or retained and canceled by the Trustee. At
any time prior to such  cancellation,  if any beneficial  interest in the Global

                                       23
<PAGE>

Security is  exchanged  for  Definitive  Securities,  redeemed,  repurchased  or
canceled,  the  aggregate  principal  amount of Securities  represented  by such
Global Security shall be reduced accordingly and an endorsement shall be made on
such Global Security by the Trustee to reflect such reduction.

registrations  of  transfers  and  exchanges  effected in  accordance  with this
Indenture,  the Company  shall execute and the Trustee  shall  authenticate  the
Global Security and any Definitive  Securities at the Registrar's  request.  The
Global Security and any Definitive  Securities  issued upon any  registration of
transfer or  exchange  of  beneficial  interests  in the Global  Security or the
Definitive  Securities  shall be legal,  valid and  binding  obligations  of the
Company,  evidencing the same debt, and entitled to the same benefits under this
Indenture,  as the Definitive  Securities or Global Securities  surrendered upon
such registration of transfer or exchange.

register the transfer of or exchange Securities during a period beginning at the
opening of business  on a Business  Day 15 days before the day of mailing of any
notice of redemption of Securities  under Section 11.05 hereof and ending at the
close of business on the day of such  mailing or (b) register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

herein),  but the Company may require  payment of a sum  sufficient to cover any
transfer tax or similar  governmental  charge  payable in  connection  therewith
(other  than such  transfer  tax or similar  governmental  charge  payable  upon
exchanges  pursuant to Sections 3.04, 9.06 or 11.08 hereof,  which shall be paid
by the Company).

          Prior  to due  presentment  to the  Trustee  for  registration  of the
transfer of any  Security,  the Trustee,  any Agent and the Company may deem and

if any, and interest on such  Security  and for all other  purposes  whatsoever,
whether or not such Security is overdue,  and none of the Trustee,  any Agent or
the Company shall be affected by notice to the contrary.

          (g)   General   Provisions    Relating   to   the   Global   Security.
Notwithstanding any other provision in this Indenture, no Global Security may be
transferred to, or registered or exchanged for Securities registered in the name
of, any Person other than the Depositary for such Global Security or any nominee
thereof, and no such transfer may be registered,  unless (i) such Depositary (A)
notifies the Company  that it is  unwilling or unable to continue as  Depositary
for such Global Security or (B) ceases to be a clearing agency  registered under
the  Exchange  Act,  (ii) the  Company  delivers  to the  Trustee  an  Officers'
Certificate  stating  that  such  Global  Security  shall  be  so  transferable,
registrable, and exchangeable, and such transfers shall be registrable, or (iii)

the  Securities  evidenced by such Global  Security.  Notwithstanding  any other
provision in this  Indenture,  a Global  Security to which the  restriction  set

                                       24
<PAGE>

forth in the preceding  sentence  shall have ceased to apply may be  transferred
only to, and may be registered and exchanged for Securities  registered  only in
the name or names of, such Person or Persons as the  Depositary  for such Global
Security shall have directed and no transfer  thereof other than such a transfer
may be registered.  Every Security authenticated and delivered upon registration

this Indenture,  the Company may deliver  Securities  executed by the Company to
the  Trustee  for  authentication,   together  with  a  Company  Order  for  the

purchaser,  the Company  shall execute and the Trustee  shall  authenticate  and
deliver, in lieu of any such destroyed,  lost or stolen Security, a new Security
of like tenor and  principal  amount and bearing a number not  contemporaneously
outstanding.

governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

stolen  Security  shall be at any  time  enforceable  by  anyone,  and  shall be
entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Securities duly issued hereunder.

immediately  by a notice in writing to the Company  (and to the Trustee if given
by the holders); and upon any such declaration all amounts payable in respect of
the Securities shall become immediately due and payable.  If an Event of Default
specified  in Section  5.01(h) or 5.01(i)  occurs,  then all of the  outstanding
Securities  shall ipso facto become and be immediately  due and payable  without
any declaration or other act on the part of the Trustee or any Holder.

by the Trustee,  the Holders of a majority in aggregate  principal amount of the
Outstanding  Securities,  by written notice to the Company and the Trustee,  may

lawful, interest upon overdue interest,  premium and Liquidated Damages, if any,
and overdue  principal at the rate borne by the Securities and (D) all sums paid
or advanced by the Trustee hereunder and the reasonable compensation,  expenses,
disbursements and advances of the Trustee,  its agents and counsel; and (ii) all
Events of Default,  other than the  non-payment  of amounts of principal of (and
premium and Liquidated  Damages, if any, on) or interest on the Securities which
have become due solely by such declaration of  acceleration,  have been cured or
waived,  as  provided  by Section  5.13.  No such  rescission  shall  affect any
subsequent default or impair any right consequent thereon.

SECTION V.3    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

          The Company covenants that if

               (10 default is made in the payment of any interest or  Liquidated

     if any, becomes due and payable and such default  continues for a period of
     30 days, or

               (20 default is made in the payment of  principal  of (or premium,
     if any, on) any Security at the Maturity thereof,

Holders  of such  Securities,  the whole  amount  then due and  payable  on such
Securities  for  principal  (and  premium,  if any) and interest and  Liquidated
Damages,  if any,  and, to the extent  that  payment of such  interest  shall be

                                       34
<PAGE>

legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest and Liquidated Damages, if any, at the rate borne by the
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover  the  costs  and  expenses  of  collection,  including  the  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel.

          If an Event of Default  occurs and is  continuing,  the Trustee may in
its  discretion  proceed to protect and enforce its rights and the rights of the
Holders by such appropriate  judicial proceedings as the Trustee shall deem most
effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION V.4    TRUSTEE MAY FILE PROOFS OF CLAIM

          In case of any  judicial  proceeding  relative  to the Company (or any
other obligor upon the Securities),  its property or its creditors,  the Trustee
shall  be  entitled  and  empowered,  by  intervention  in  such  proceeding  or
otherwise,  to take any and all actions authorized under the Trust Indenture Act
in order to have  claims of the  Holders  and the  Trustee  allowed  in any such
proceeding.  In  particular,  the  Trustee  shall be  authorized  to collect and
receive any moneys or other  property  payable or deliverable on any such claims
and to distribute  the same;  and any custodian,  receiver,  assignee,  trustee,
liquidator,  sequestrator  or  other  similar  official  in  any  such  judicial
proceeding  is hereby  authorized  by each  Holder to make such  payments to the
Trustee and, in the event that the Trustee  shall  consent to the making of such
payments  directly to the  Holders,  to pay to the Trustee any amount due it for
the  reasonable  compensation,  expenses,  disbursements  and  advances  of  the
Trustee,  its agents and counsel,  and any other  amounts due the Trustee  under
Section 6.07.

          No  provision  of this  Indenture  shall be  deemed to  authorize  the
Trustee  to  authorize  or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities  or the rights of any Holder  thereof or to authorize  the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION V.5    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES

          All rights of action and claims under this Indenture or the Securities
may be prosecuted  and enforced by the Trustee  without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such  proceeding  instituted by the Trustee shall be brought in its own name
as trustee of an express  trust,  and any  recovery  of  judgment  shall,  after
provision   for  the   payment  of  the   reasonable   compensation,   expenses,
disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable  benefit  of the  Holders  of the  Securities  in  respect of which such
judgment has been recovered.

     (and  premium,  if  any)  and  interest  and  Liquidated  Damages,  if any,
     respectively; and

          THIRD:  To the payment of the remainder,  if any, to the Company,  its
     successors or assigns or to whomsoever may be lawfully  entitled to receive
     the same or as a court of competent jurisdiction may direct.

to  authorize  any  court to  require  such an  undertaking  or to make  such an
assessment in any suit instituted by the Trustee or the Company.

performance  of this  Indenture;  and the  Company  (to the  extent  that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law

condition  at least  annually,  pursuant  to law or to the  requirements  of any
supervising or examining  authority,  then for the purposes of this Section, the
combined  capital and surplus of such Person  shall be deemed to be its combined
capital  and  surplus as set forth in its most  recent  report of  condition  so
published.  If at any time the Trustee  shall cease to be eligible in accordance
with the provisions of this Section,  it shall resign  immediately in the manner
and with the effect hereinafter specified in this Article.

SECTION VI.10  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR

          (10 No  resignation  or removal of the Trustee and no appointment of a
successor  Trustee  pursuant to this Article  shall become  effective  until the
acceptance of  appointment  by the  successor  Trustee under Section 6.11. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the  Trustee  within 30 days after the giving of such notice of  resignation  or
removal,  the  Trustee  resigning  or being  removed may  petition  any court of
competent jurisdiction for the appointment of a successor Trustee.

          (20 The  Trustee  may  resign  at any time by  giving  written  notice
thereof to the Company.

     written  request  therefor  by the  Company or by any Holder who has been a
     bona fide Holder of a Security for at least six months, or

               (20 the Trustee shall cease to be eligible under Section 6.09 and
     shall fail to resign after  written  request  therefor by the Company or by
     any such Holder, or

               (30 the  Trustee  shall  become  incapable  of acting or shall be
     adjudged a bankrupt  or  insolvent  or a receiver  of the Trustee or of its
     property  shall be  appointed  or any public  officer  shall take charge or

     rehabilitation, conservation or liquidation,

                                       42
<PAGE>

then,  in any such case,  (i) the Company by a Board  Resolution  may remove the
Trustee,  or (ii) subject to Section  5.14,  any Holder who has been a bona fide
Holder of a Security  for at least six months  may, on behalf of himself and all
others similarly situated,  petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (50 If the Trustee  shall  resign,  be removed or become  incapable of
acting,  or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution,  shall promptly appoint a successor Trustee. If,
within  one  year  after  such  resignation,  removal  or  incapability,  or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders  of a  majority  in  principal  amount  of  the  Outstanding  Securities
delivered  to the Company and the retiring  Trustee,  the  successor  Trustee so
appointed shall,  forthwith upon its acceptance of such appointment,  become the
successor  Trustee and supersede the successor Trustee appointed by the Company.
If no  successor  Trustee  shall have been so  appointed  by the  Company or the
Holders and accepted appointment in the manner hereinafter provided,  any Holder
who has been a bona fide  Holder of a Security  for at least six months  may, on
behalf of  himself  and all others  similarly  situated,  petition  any court of
competent jurisdiction for the appointment of a successor Trustee.

          (60 The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to all Holders in the
manner  provided  in Section  1.06.  Each notice  shall  include the name of the
successor Trustee and the address of its Corporate Trust Office.

SECTION VI.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring  Trustee an instrument  accepting
such  appointment,  and  thereupon  the  resignation  or removal of the retiring
Trustee shall become effective and such successor  Trustee,  without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the  retiring  Trustee;  but,  on  request  of the  Company or the
successor  Trustee,  such retiring  Trustee shall,  upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights,  powers  and  trusts of the  retiring  Trustee  and shall  duly  assign,
transfer  and deliver to such  successor  Trustee all property and money held by
such  retiring  Trustee  hereunder,  subject to its lien provided for in Section
6.07. Upon request of any such successor Trustee,  the Company shall execute any
and all  instruments  for more fully and certainly  vesting in and confirming to
such successor Trustee all such rights, powers and trusts.

          No successor  Trustee shall accept its appointment  unless at the time
of such acceptance such successor  Trustee shall be qualified and eligible under
this Article.

SECTION VI.12  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS

          Any  corporation  into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation  succeeding to all or substantially all the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided such

                                       43
<PAGE>

corporation  shall be  otherwise  qualified  and  eligible  under this  Article,
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not  delivered,  by the Trustee  then in office,  any  successor  by merger,
conversion  or  consolidation  to such  authenticating  Trustee  may adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION VI.13  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY

          If and when the  Trustee  shall be or become a creditor of the Company
(or any other obligor upon the Securities),  the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION VI.14  APPOINTMENT OF CO-TRUSTEE

          It is the purpose of this  Indenture  that there shall be no violation
of any law of any  jurisdiction,  including  particularly  the law of New  York,
denying or restricting  the right of banking  corporations  or  associations  to
transact business as Trustee in such jurisdiction. It is recognized that in case
of litigation under this Indenture, and in particular in case of the enforcement
on default, or in case the Trustee deems that by reason of any present or future
law of any  jurisdiction  it may  not  exercise  any of the  powers,  rights  or
remedies  herein  granted to the  Trustee or hold  title to the  properties,  in
trust,  as herein  granted,  or take any other  action which may be desirable or
necessary in connection therewith,  it may be necessary that the Trustee appoint
an  additional  individual  or  institution  as a separate  or  co-trustee.  The
following provisions of this Section 6.14 are adopted to these ends.

          In the event that the Trustee  appoints an  additional  individual  or
institution as a separate or co-trustee,  each and every remedy,  power,  right,
claim,  demand,  cause of action,  immunity,  estate,  title,  interest and lien
expressed  or  intended by this  Indenture  to be  exercised  by or vested in or
conveyed to the Trustee with respect  thereto shall be exercisable by and vested
in such separate or co-trustee  but only to the extent  necessary to enable such
separate or co-trustee to exercise such powers,  rights and remedies,  and every
covenant and  obligation  necessary to the exercise  thereof by such separate or
co-trustee shall run to and be enforceable by such separate or co-trustee.

          Should any  instrument in writing be required by the separate  trustee
or co-trustee  so appointed by the Trustee for more fully and certainly  vesting
in and confirming to him or it such properties,  rights,  powers, trusts, duties
and obligations,  any and all such instruments in writing shall, on request,  be
executed,  acknowledged  and  delivered  by the  Company.  In case any  separate
trustee or co-trustee,  or a successor to either, shall die, become incapable of
acting,  resign or be removed,  all the  estates,  properties,  rights,  powers,
trusts, duties and obligation of such separate trustee or co-trustee,  so far as
permitted  by law,  shall  vest in and be  exercised  by the  Trustee  until the
appointment  of  a  new  trustee  or  successor  to  such  separate  trustee  or
co-trustee.

receipt of a new list so furnished.

Trust Indenture Act.

          (30 Every Holder of  Securities,  by  receiving  and holding the same,

disclosure of  information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
sixty days after each May 15 following  the date of this  Indenture,  deliver to
Holders  a brief  report,  dated  as of such  May 15,  which  complies  with the
provision of such Section 313(a).

          (20 A copy of each such report shall, at the time of such transmission
to Holders,  be filed by the  Trustee  with each stock  exchange  upon which the

                                       45

assets of the Company and its Restricted Subsidiaries on a consolidated basis to
any Person, unless:

          (a) either (i) the Company is the  surviving  corporation  or (ii) the

the  Company  or such  Restricted  Subsidiary  is  merged  or the  Person  which
acquires,  by  conveyance,  transfer or lease,  the properties and assets of the
Company or such Restricted  Subsidiary,  as the case may be, substantially as an
entirety (the  "Surviving  Entity") (A) shall be a  corporation,  partnership or
trust  organized  and validly  existing  under the laws of the United  States of
America,  any state thereof or the District of Columbia and (B) shall  expressly
assume, by a supplemental  indenture  executed and delivered to the Trustee,  in

the  Securities  and the  performance  and  observance of every covenant of this
Indenture on the part of the Company to be performed or observed;

          (b) immediately  after giving effect to such  transaction or series of

                                    ARTICLE X

                                    COVENANTS

SECTION X.1    PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST

          The  Company  will  duly  and  punctually  pay the  principal  of (and
premium, if any) and interest (and Liquidated Damages, if any) on the Securities
in accordance with the terms of the Securities and this Indenture.

SECTION X.2    MAINTENANCE OF OFFICE OR AGENCY

          The Company will maintain in the Borough of Manhattan, The City of New
York,  New York,  an  office or agency  where  Securities  may be  presented  or
surrendered for payment, where Securities may be surrendered for registration of
transfer  or  exchange  and where  notices and demands to or upon the Company in
respect of the  Securities  and this  Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in the
location,  of such office or agency.  If at any time the  Company  shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof,  such presentations,  surrenders,  notices and demands
may be made or served at the  Corporate  Trust  Office of the  Trustee,  and the
Company  hereby   appoints  the  Trustee  as  its  agent  to  receive  all  such
presentations,  surrenders,  notices  and  demands.  The  Trustee may resign any
agency  capacity  under  this  Indenture  upon 30 days'  written  notice  to the
Company.

          The  Company  may also from time to time  designate  one or more other
offices or agencies  (in or outside the  Borough of  Manhattan,  The City of New
York, New York) where the Securities may be presented or surrendered  for any or
all such purposes and may from time to time rescind such designations; provided,

                                       49
<PAGE>

however,  that no such designation or rescission shall in any manner relieve the
Company of its  obligation  to  maintain  an office or agency in the  Borough of
Manhattan  The City of New York,  New York for such  purposes.  The Company will
give prompt written  notice to the Trustee of any such  designation or remission
and of any change in the location of any such other office or agency.

SECTION X.3    MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST

          If the Company shall at any time act as its own Paying Agent, it will,
on or  before  each  due  date of the  principal  of (and  premium,  if any,) or
interest (and Liquidated  Damages,  if any) on any of the Securities,  segregate
and  hold in  trust  for the  benefit  of the  Persons  entitled  thereto  a sum
sufficient  to pay  the  principal  (and  premium,  if  any)  or  interest  (and
Liquidated  Damages,  if any) so  becoming  due until such sums shall be paid to
such  Persons or  otherwise  disposed of as herein  provided  and will  promptly
notify the Trustee of its action or failure so to act.

          Whenever the Company  shall have one or more Paying  Agents,  it will,
prior to each due date of the  principal  of (and  premium,  if any) or interest
(and Liquidated Damages, if any) on any Securities,  deposit with a Paying Agent
a sum  sufficient  to pay the principal  (and premium,  if any) or interest (and
Liquidated  Damages,  if any) so becoming  due, such sum to be held in trust for
the benefit of the  Persons  entitled to such  principal,  premium,  interest or
Liquidated  Damages,  and (unless  such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

          The  Company  will cause each  Paying  Agent other than the Trustee to
execute  and  deliver to the Trustee an  instrument  in which such Paying  Agent
shall agree with the Trustee,  subject to the  provisions of this Section,  that
such Paying Agent will:

               (1) hold all sums held by it for the payment of the  principal of
     (and  premium,  if any) or interest  (and  Liquidated  Damages,  if any) on
     Securities in trust for the benefit of the Persons  entitled  thereto until
     such sums shall be paid to such Persons or otherwise  disposed of as herein
     provided;

               (2) give the Trustee notice of any default by the Company (or any
     other  obligor  upon  the  Securities)  in the  making  of any  payment  of
     principal (and premium,  if any) or interest (and  Liquidated  Damages,  if
     any); and

               (3) at any time during the continuance of any such default,  upon
     the written  request of the Trustee,  forthwith pay to the Trustee all sums
     so held in trust by such Paying Agent.

          The  Company  may at any  time,  for  the  purpose  of  obtaining  the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such paying  Agent,  such sums to be held by the Trustee
upon the same  trusts as those upon which such sums were held by the  Company or
such Paying  Agent;  and,  upon such payment by any Paying Agent to the Trustee,

                                       50
<PAGE>

such Paying Agent shall be released from all further  liability  with respect to
such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company,  in trust for the payment of the principal of (and  premium,  if
any) or interest on any Security  and  remaining  unclaimed  for two years after
such principal (and premium,  if any) or interest (and  Liquidated  Damages,  if
any) has become due and payable shall be paid to the Company on Company Request,
or (if then held by the Company)  shall be discharged  from such trust;  and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment  thereof,  and all  liability  of the Trustee or
such Paying  Agent with respect to such trust  money,  and all  liability of the
Company as trustee thereof, shall thereupon cease;  provided,  however, that the
Trustee or such Paying Agent, before being required to make any, such repayment,
may at the expense of the Company  cause to be  published  once,  in a newspaper
published in the English  language,  customarily  published on each Business Day
and of general  circulation  in the Borough of Manhattan,  The City of New York,
New York,  notice  that such  money  remains  unclaimed  and that,  after a date
specified  therein,  which  shall not be less than 30 days from the date of such
publication,  any unclaimed  balance of such money then remaining will be repaid
to the Company.

SECTION X.4    EXISTENCE

          Subject to Article Eight,  the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and
rights (charter and statutory); provided, however, that the Company shall not be
required to preserve any such right or franchise if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and that the loss thereof is not  disadvantageous in
any material respect to the Holders.

SECTION X.5    MAINTENANCE OF PROPERTIES

          The Company will cause all properties  (including  broadcast licenses)
used or useful in the  conduct of its  business  or the  business  of any of its
Subsidiaries  to be maintained  and kept in good  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 the Company 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 shall prevent the
Company  from  discontinuing  the  operation  or  maintenance  of  any  of  such
properties if such  discontinuance  is, as determined in the good faith judgment
of the Company,  desirable in the conduct of its business or the business of any
of its  Subsidiaries  and not  disadvantageous  in any  material  respect to the
Holders.

SECTION X.6    PAYMENT OF TAXES AND OTHER CLAIMS

          The Company will pay or  discharge or cause to be paid or  discharged,
before  the  same  shall  become  delinquent,  (1) all  taxes,  assessments  and
governmental  charges  levied  or  imposed  upon  the  Company  or  any  of  its
Subsidiaries  or upon the  income,  profits or property of the Company or any of

                                       51
<PAGE>

its  Subsidiaries,  and (2) all lawful claims for labor,  materials and supplies
which, if unpaid, might by law become a lien upon the property of the Company or
any of its  Subsidiaries;  provided,  however,  that the  Company  shall  not be
required to pay or  discharge  or cause to be paid or  discharged  any such tax,
assessment,  charge or claim whose  amount,  applicability  or validity is being
contested in good faith by appropriate proceedings.

SECTION X.7    MAINTENANCE OF INSURANCE

          The Company shall,  and shall cause its  Subsidiaries  to keep, at all
times all of their  properties  which are of an insurable nature insured against
loss or damage in a manner determined  appropriate by the Company  (evidenced by
an Officers'  Certificate,  a copy of which shall be delivered to the Trustee on
an annual basis) with insurers  believed by the Company to be  responsible.  The
Company shall,  and shall cause its  Subsidiaries  to, (i) use the proceeds from
any such insurance as required  under the terms of Bank Credit  Facilities or to
repay or prepay any then  outstanding Pari Passu Debt of the Company or any Debt
of a Restricted Subsidiary, (ii) use the proceeds from any such insurance policy
to repair,  replace or  otherwise  restore the  property to which such  proceeds
relate or (iii) invest such proceeds in other assets related to the Company.  In
lieu of or  supplemental to such insurance the Company may adopt such other plan
or method of protection in respect of properties,  whether by the  establishment
of an insurance  fund or reserve to be held and applied to make good losses from
casualties,  or otherwise, and conforming to the practices of other corporations
maintaining  systems of  self-insurance,  as may be  determined  by the  Company
(evidenced  by an Officers'  Certificate,  a copy of which shall be delivered to
the Trustee on an annual basis).

SECTION X.8    LIMITATION ON DEBT

          The Company  will not, and will not permit any  Restricted  Subsidiary
to, Incur any Debt; provided,  however,  that the Company may Incur Debt and may
permit a Restricted  Subsidiary to incur Debt if at the time of such  Incurrence
and after giving effect thereto the  Consolidated  Cash Flow Ratio would be less
than 5.5 to 1.0.

          In making the foregoing calculation, there shall be excluded from Debt
for purposes of  calculating  the  Consolidated  Cash Flow Ratio all Debt of the
Company and its Restricted  Subsidiaries  incurred pursuant to clause (i) of the
definition  of  Permitted  Debt,  and pro forma  effect will be given to (i) the
Incurrence  of the Debt to be incurred and the  application  of the net proceeds
therefrom to refinance other Debt and (ii) the acquisition (whether by purchase,
merger or otherwise) or  disposition  (whether by sale,  merger or otherwise) of
any  company,  entity or business  acquired or disposed of by the Company or its
Restricted  Subsidiaries,  as the case may be,  since  the first day of the most
recent full fiscal quarter,  as if such  acquisition or disposition  occurred at
the beginning of the most recent full fiscal quarter.

          Notwithstanding  the  foregoing  limitation,  the Company may, and may
permit its  Restricted  Subsidiaries  to, Incur the  following  additional  Debt
("Permitted Debt"):

          (i) Debt under the Bank Credit  Facilities in an aggregate  amount not
to exceed $100.0 million at any one time outstanding,  less any amounts by which

                                       52
<PAGE>

the commitments  thereunder are permanently  reduced  pursuant to the provisions

Subsidiary or owed by any wholly-owned  Restricted  Subsidiary to the Company or
any other wholly-owned Restricted Subsidiary (provided that such Debt is held by
the Company or such wholly-owned Restricted Subsidiary and provided further that
in the case of Debt owed by the Company, such Debt is Subordinated Debt);

          (iv) Debt represented by the Securities;

limitation, shares of Capital Stock;

          (viii) Debt of the  Company or any  Restricted  Subsidiary  (including
trade letters of credit) in respect of purchase money obligations; provided that

million;

          (ix)  Debt  arising  from the  honoring  by a bank or other  financial
institution of a check, draft or similar  instrument drawn against  insufficient
funds  in  the  ordinary  course  of  business,   provided  that  such  Debt  is
extinguished within two Business Days of its Incurrence; and

          (x)  any  renewals,   extensions,   substitutions,   refinancings   or
replacements  (each,  for  purposes  of this  clause,  a  "refinancing")  of any
outstanding Debt, other than Debt Incurred pursuant to clause (i), (vii) or (ix)
of this definition,  including any successive  refinancings  thereof, so long as
(A) any  such  new Debt is in a  principal  amount  that  does  not  exceed  the
principal amount (or, if such Debt being refinanced  provides for an amount less
than the principal  amount  thereof to be due and payable upon a declaration  of
acceleration  thereof,  such lesser amount as of the date of  determination)  so
refinanced,  plus the amount of any premium  required  to be paid in  connection
with such refinancing pursuant to the terms of the Debt refinanced or the amount
of any premium  reasonably  determined by the Company as necessary to accomplish
such refinancing by means of a tender offer or privately negotiated  repurchase,
plus the amount of  reasonable  expenses  Incurred by the Company in  connection
with such refinancing,  (B) in the case of any refinancing of Subordinated Debt,
such new Debt is made  subordinate to the Securities at least to the same extent
as the  Debt  being  refinanced,  (C)  in the  case  of any  refinancing  of the

                                       53
<PAGE>

Securities  or any  Pari  Passu  Debt,  such  new  Debt is made  pari  passu  or
subordinated to the Securities,  and (D) such  refinancing Debt does not have an
Average  Life less than the Average Life of the Debt being  refinanced  and does
not have a final scheduled maturity earlier than the final scheduled maturity of
the Debt  being  refinanced,  or permit  redemption  at the option of the holder
earlier than the earliest  date of redemption at the option of the holder of the
Debt being refinanced.

          (j) Investments in Benbow PCS Ventures, Inc. of up to $50.0 million in
     the aggregate; and

          (k) make any other  payment or payments  of up to $5.0  million in the
     aggregate which would otherwise constitute a Restricted Payment.

          The Restricted  Payments described in clauses (b), (c), (e), (f), (g),
(h), (i), (j) and (k) of this paragraph will be Restricted Payments that will be
permitted to be taken in accordance with the preceding paragraph but will reduce
the amount that would  otherwise  be available  for  Restricted  Payments  under
clause (iii) of the first paragraph of this Section and the Restricted  Payments
described in clauses (a) and (d) of the preceding  paragraph  will be Restricted
Payments  that will be permitted to be taken in  accordance  with the  preceding
paragraph  and will not reduce the amount that would  otherwise be available for
Restricted Payments under clause (iii) of the first paragraph of this Section.

          For the purpose of making any calculations  under this Indenture,  (i)
an  Investment  will  include  the fair  market  value of the net  assets of any
Restricted  Subsidiary at the time that such Restricted Subsidiary is designated
an Unrestricted  Subsidiary and will, for the purpose of this covenant,  exclude
the fair market value of the net assets of any  Unrestricted  Subsidiary that is
designated as a Restricted Subsidiary,  (ii) any property transferred to or from
an  Unrestricted  Subsidiary  will be valued at fair market value at the time of
such transfer; provided that, in each case, the fair market value of an asset or
property is as determined by the Board of Directors of the Company in good faith
and (iii) subject to the  foregoing,  the amount of any Restricted  Payment,  if
other than cash,  will be  determined  by the Board of Directors of the Company,
whose good faith determination will be conclusive.

          If the aggregate  amount of all Restricted  Payments  calculated under
the foregoing provision includes an Investment in an Unrestricted  Subsidiary or
other Person that thereafter  becomes a Restricted  Subsidiary,  such Investment
will no longer be counted as a Restricted  Payment for  purposes of  calculating
the aggregate amount of Restricted Payments.

          If an Investment resulted in the making of a Restricted  Payment,  the
aggregate  amount of all  Restricted  Payments  calculated  under the  foregoing
provision will be reduced by the amount of any net reduction in such  Investment
(resulting from the payment of interest or dividend, loan repayment, transfer of
assets or  otherwise)  to the extent such net  reduction  is not included in the
Company's  Consolidated  Adjusted Net Income;  provided that the total amount by
which the  aggregate  amount of all  Restricted  Payments may be reduced may not
exceed the  lesser of (x) the cash  proceeds  received  by the  Company  and its
Restricted  Subsidiaries  in  connection  with  such net  reduction  and (y) the
initial amount of such Investment.

                                       57

          In  computing  Consolidated  Cash Flow of the Company  under the first
paragraph  of this  Section  10.09,  (i) the Company  may use audited  financial
statements for the portions of the relevant  period for which audited  financial
statements are available on the date of  determination  and unaudited  financial
statements  and other current  financial  data based on the books and records of
the Company for the  remaining  portion of such period and (ii) the Company will
be  permitted  to rely in good  faith  on the  financial  statements  and  other
financial  data  derived  from the books and  records  of the  Company  that are
available  on the  date of  determination.  If the  Company  makes a  Restricted
Payment which,  at the time of the making of such Restricted  Payment,  would in
the good  faith  determination  of the  Board of  Directors  of the  Company  be
permitted under the requirements of this Indenture, such Restricted Payment will
be deemed to have been made in compliance  with this  Indenture  notwithstanding
any  subsequent  adjustments  made  in good  faith  to the  Company's  financial
statements  affecting  Consolidated  Adjusted  Net Income of the Company for any
period.

SECTION X.10 LIMITATIONS ON DIVIDENDS AND OTHER PAYMENT  RESTRICTIONS  AFFECTING
             RESTRICTED SUBSIDIARIES

          The Company  will not, and will not permit any  Restricted  Subsidiary
to, create,  assume or otherwise cause or suffer to exist or to become effective
any  consensual  encumbrance  or  restriction  on the ability of any  Restricted
Subsidiary  to (a) pay any  dividends  or make any  other  distributions  on its
Capital  Stock;  (b) make payments in respect of any Debt owed to the Company or
any  Restricted  Subsidiary;  (c) make loans or  advances  to the Company or any
Restricted  Subsidiary;  or (d)  transfer  any of its  property or assets to the
Company or any Restricted Subsidiary, other than (i) those under the Bank Credit
Facilities  existing as of the date of issuance  of the  Securities,  (ii) those
under other Debt of the Company, Parent or any Restricted Subsidiary existing as
of the date of issuance of the  Securities,  (iii) those as may be  contained in
future agreements provided that they are no more restrictive than those referred
to in the immediately preceding clauses (i) and (ii), (iv) those required by the
Securities,  (v) customary  non-assignment  or sublease  provisions of any lease
governing a leasehold interest of the Company or any Restricted Subsidiary, (vi)
consensual encumbrances or restrictions binding upon any Person at the time such
Person  becomes  a  Subsidiary  of the  Company;  provided,  however,  that such
encumbrances  or  restrictions  were not incurred in anticipation of such Person
becoming a  Subsidiary  of the  Company,  (vii)  encumbrances  and  restrictions
imposed  by  applicable  law  or  (viii)  any  restrictions  with  respect  to a
Restricted  Subsidiary  imposed  pursuant to an agreement which has been entered
into for the sale or  disposition  of all or  substantially  all of the  Capital
Stock  or  assets  of such  Subsidiary  pending  the  closing  of  such  sale or
disposition.  Nothing  contained in this covenant shall prevent the Company from
entering into any agreement permitted by Section 10.17; provided,  however, that
the  encumbrance or restriction in any such agreement is limited to the transfer
of the property or assets which is subject to such agreement.

SECTION X.11   LIMITATION ON TRANSACTIONS WITH AFFILIATES AND RELATED PERSONS

          The Company  will not, and will not permit any  Restricted  Subsidiary
to, directly or indirectly, enter into any transaction or series of transactions
after  the date of this  Indenture  with any  Affiliate  of the  Company  or any
Related Person (other than the Company or a wholly-owned Restricted Subsidiary),
unless  (i) such  transaction  or  series  of  transactions  is on terms no less
favorable to the Company or such Restricted  Subsidiary than those that could be

                                       58
<PAGE>

obtained in a comparable arm's-length  transaction with an entity that is not an
Affiliate  or a  Related  Person;  and (ii) if such  transaction  or  series  of
transactions  involves aggregate  consideration in excess of $1.0 million,  then
such  transaction  or series of  transactions  is  approved by a majority of the
Board of Directors of the Company,  including  the approval of a majority of the
Disinterested  Directors,  and is  evidenced  by a  resolution  of the  Board of
Directors of the Company.  Any such transaction or series of transactions  shall
be  conclusively  deemed to be on terms no less favorable to the Company or such
Restricted  Subsidiary  than  those that could be  obtained  in an  arm's-length
transaction if such  transaction or  transactions  are approved by a majority of
the Board of Directors of the Company, including a majority of the Disinterested
Directors,  and are  evidenced by a resolution  of the Board of Directors of the
Company.

          This covenant will not apply to (i)  transactions  between the Company
or any of its Restricted  Subsidiaries and any employee of the Company or any of
its  Restricted  Subsidiaries  that are entered into in the  ordinary  course of
business, (ii) the payment of reasonable and customary regular fees and expenses
to directors of the Company,  (iii) the making of indemnification,  contribution
or similar  payments to any director or officer of the Company or any Restricted
Subsidiary of the Company under the  Company's or such  Restricted  Subsidiary's
charter or by-laws (as each may be amended after the date of this  Indenture) or
any  indemnification  or  similar  agreement  between  the  Company  or any such
Restricted  Subsidiary and any of its directors or officers  (collectively,  the
"Indemnification  Agreements") or (iv) the entering into of any  Indemnification
Agreements  with any current or future  directors  or officers of the Company or
any Restricted Subsidiary of the Company.


SECTION X.12   LIMITATION ON CERTAIN ASSET SALES

          (1)  The  Company  will  not,  and  will  not  permit  any  Restricted
Subsidiary to, engage in any Asset Sale unless (i) the consideration received by
the Company or such  Restricted  Subsidiary for such Asset Sale is not less than
the  fair  market  value  of the  assets  sold (as  determined  by the  Board of
Directors of the Company, whose good faith determination will be conclusive) and
(ii) the  consideration  received  by the  Company  or the  relevant  Restricted
Subsidiary  in respect of such Asset Sale  consists  of at least 85% (A) cash or
cash equivalents  and/or (B) the assumption by the transferee of Pari Passu Debt
of the Company or any Debt of a Restricted Subsidiary and release of the Company
or such Restricted Subsidiary from all liability on such Debt.

          (2) If the Company or any  Restricted  Subsidiary  engages in an Asset
Sale, the Company may use the Net Cash Proceeds thereof,  within 12 months after
such Asset Sale, to (i) make a permanent  reduction of amounts outstanding under
the Bank Credit  Facilities or repay or prepay any then  outstanding  Pari Passu
Debt of the Company or any Debt of a  Restricted  Subsidiary  or (ii) invest (or
enter  into a  legally  binding  agreement  to invest  (within  90 days)) in (A)
properties and assets to replace the properties and assets that were the subject
of the  Asset  Sale,  or (B)  properties  and  assets  that  will be used in the
telecommunications  businesses of the Company or its Restricted Subsidiaries, as
the case may be. If any such legally  binding  agreement to invest such Net Cash
Proceeds is terminated, then the Company may, within 90 days of such termination
or within 12 months of such Asset Sale, whichever is later, invest such Net Cash
Proceeds as provided in clause (i) or (ii) (without regard to the  parenthetical
in such clause (ii)) above.  Pending  application of the Net Cash Proceeds of an

                                       59
<PAGE>

Asset Sale  pursuant  to clause  (ii)  above,  the Company may use such Net Cash
Proceeds to reduce temporarily borrowings under the Bank Credit Facilities.  The
amount of such Net Cash Proceeds not so used as set forth in this  paragraph (b)
constitutes "Excess Proceeds."

          (3) When the aggregate amount of Excess Proceeds exceeds $5.0 million,
the Company will,  within 30 days, make an Offer to Purchase from all holders of
Notes,  on a pro rata basis, in accordance with the procedures set forth in this
Indenture,  the maximum  principal amount (expressed as a multiple of $1,000) of
Notes that may be purchased with the Excess  Proceeds.  The offer price for each
Note will be payable in cash in an amount equal to 100% of the principal  amount
of such Note, plus accrued and unpaid interest and Liquidated  Damages,  if any,
to the date such  Offer to  Purchase  is  consummated.  To the  extent  that the
aggregate  principal amount of Notes tendered pursuant to such Offer to Purchase
is less than the Excess Proceeds,  the Company may use the then remaining Excess
Proceeds for other general corporate  purposes not prohibited by this Indenture.
If the aggregate principal amount of Notes validly tendered and not withdrawn by
holders  thereof  exceeds the Excess  Proceeds,  Notes to be  purchased  will be
selected on a pro rata basis.  Upon  completion  of such Offer to Purchase,  the
amount of Excess Proceeds will be reset to zero.

          (4) Not later than the date of the Offer  with  respect to an Offer to
Purchase  pursuant  to this  Section  10.12,  the Company  shall  deliver to the
Trustee  (i) an  Officers'  Certificate  as to the  Purchase  Amount and (ii) an
Officers'  Certificate and an Opinion of Counsel as to the Company's  compliance
with the provisions of Section 10.12.

          The Company and the Trustee shall perform their respective obligations
specified  in the  Offer to  Purchase.  On or prior to the  Purchase  Date,  the
Company  shall (i) accept for  payment (on a pro rata basis,  if  necessary,  as
provided in the definition of Offer to Purchaser) Securities or portions thereof
tendered  pursuant to the Offer,  (ii) deposit with the Paying Agent (or, if the
Company  is  acting  as its own  Paying  Agent,  segregate  and hold in trust as
provided in Section  10.03) money  sufficient  to pay the Purchase  Price of all
Securities  or  portions  thereof so accepted  and (iii)  deliver or cause to be
delivered to the Trustee all  Securities so accepted  together with an Officers'
Certificate  stating the Securities or portions  thereof accepted for payment by
the Company. The Paying Agent (or the Company, if so acting) shall promptly mail
or deliver to Holders of  Securities  so accepted  payment in an amount equal to
the Purchase  Price,  and the Trustee shall  promptly  authenticate  and mail or
deliver  to such  Holders  a new  Security  equal  in  principal  amount  to any
unpurchased portion of the Security  surrendered.  Any Security not accepted for
payment  shall be  promptly  mailed or  delivered  by the  Company to the Holder
thereof.

SECTION X.13  LIMITATION  ON ISSUANCES  AND SALES OF CAPITAL STOCK OF RESTRICTED
              SUBSIDIARIES

          The Company (a) will not permit any Restricted Subsidiary to issue any
Capital  Stock  (other than to the Company or a Restricted  Subsidiary)  and (b)
will not permit any Person  (other than the Company or a Restricted  Subsidiary)
to own any Capital Stock of any Restricted Subsidiary;  provided,  however, that
this  covenant  will not prohibit (i) the issuance and sale of all, but not less
than  all,  of the  issued  and  outstanding  Capital  Stock  of any  Restricted

                                       60
<PAGE>

Subsidiary owned by the Company or any Restricted  Subsidiary in compliance with
the other provisions of this Indenture or (ii) the acquisition by the Company of
less than all of the equity ownership or Voting Stock of a Person that, upon the
consummation of such acquisition, will be a Subsidiary.

SECTION X.14   PROVISION OF FINANCIAL STATEMENTS

          The Company  will file on a timely basis with the  Commission,  to the
extent  such  filings  are  accepted  by the  Commission  and whether or not the
Company has a class of securities  registered under the Exchange Act, the annual
reports,  quarterly  reports  and  other  documents  that the  Company  would be
required to file if it were subject to Section 13 or 15 of the Exchange Act. The
Company  will also be required  (a) to file with the  Trustee,  and upon written
request,  provide to each holder of  Securities,  without  cost to such  holder,
copies of such reports and documents  within 15 days after the date on which the
Company  files such reports and  documents  with the  Commission  or the date on
which the Company  would be required to file such  reports and  documents if the
Company were so required,  and (b) if filing such reports and documents with the
Commission is not accepted by the Commission or is prohibited under the Exchange
Act,  to deliver to the Trustee  and to supply at the  Company's  cost copies of
such reports and documents to any prospective holder of Securities promptly upon
written request.

          Delivery of such reports,  information and documents to the Trustee is
for  informational  purposes  only and the  Trustee's  receipt of such shall not
constitute   constructive  notice  of  any  information   contained  therein  or
determinable  from  information  contained  therein,   including  the  Company's
compliance  with any of its  covenants  hereunder  (as to which the  Trustee  is
entitled to rely exclusively on Officers' Certificates).

SECTION X.15   CHANGE OF CONTROL

          (1) Upon the  occurrence  of a Change of Control (as  defined  below),
each  Holder  of a  Security  will have the right to  require  that the  Company
purchase such Holder's Securities,  in whole or in part in integral multiples of
$1,000. The Company shall, within 30 days following a Change of Control,  notify
the Trustee thereof and mail to each Holder an offer with respect to an Offer to
Purchase all  Outstanding  Securities  at a Purchase  Price in cash in an amount
equal to 101% of the principal  amount thereof plus accrued and unpaid interest,
and Liquidated Damages, if any, to the Purchase Date;  provided,  however,  that
installments  of interest  whose Stated  Maturity is on or prior to the Purchase
Date shall be payable to the Holders of such  Securities,  registered as such at
the close of business on the relevant  Record Dates according to their terms and
the provisions of Section 3.06.

          (2) The Company and Trustee shall perform their respective obligations
specified in the Offer to  Purchase.  Prior to the  Purchase  Date,  the Company
shall (i) accept for payment Securities or portions thereof tendered pursuant to
the Offer to Purchase, (ii) deposit with the Paying Agent (or, if the Company is
acting as its own  Paying  Agent,  segregate  and hold in trust as  provided  in
Section  10.03) money  sufficient to pay the Purchase Price of all Securities or
portions  thereof so accepted and (iii)  deliver or cause to be delivered to the
Trustee  all  Securities  so accepted  together  with an  Officers'  Certificate
stating the Securities or portions  thereof accepted for payment by the Company.
The Paying  Agent  shall  promptly  after the  Purchase  Date mail or deliver to
Holders of  Securities  so accepted  payment in an amount  equal to the Purchase

                                       61
<PAGE>

Price,  and the Trustee shall promptly  authenticate and mail or deliver to such
Holders  a  new  Security  or  Securities  equal  in  principal  amount  to  any
unpurchased portion of the Security  surrendered as requested by the Holder. Any
Security not accepted for payment  shall be promptly  mailed or delivered by the
Company to the Holder thereof.

          (3) A "Change of Control" means the occurrence of any of the following
events:

               (1) any  "person"  or "group" (as such terms are used in Sections
     13(d) and 14(d) of the  Exchange  Act) becomes the  "beneficial  owner" (as
     defined in Rules  13d-3 and 13d-5  under the  Exchange  Act,  except that a
     Person shall be deemed to have  "beneficial  ownership"  of all  securities
     that  such  Person  has  the  right  to  acquire,  whether  such  right  is
     exercisable  immediately  or only after the  passage of time),  directly or

     Voting Stock of the Company or Parent;

               (ii) the Company or Parent  consolidates  with, or merges with or
     into, another Person or conveys, transfers, leases or otherwise disposes of
     all or  substantially  all of its  assets  to  any  Person,  or any  Person
     consolidates  with, or merges with or into,  the Company or Parent,  in any
     such event pursuant to a transaction in which the outstanding  Voting Stock
     of the  Company  or  Parent  is  converted  into  or  exchanged  for  cash,
     securities or other property, other than any such transaction where (i) the
     outstanding  Voting  Stock of the  Company  or Parent is not  converted  or
     exchanged at all (except to the extent necessary to reflect a change in the
     jurisdiction  of  incorporation)  or is converted into or exchanged for (A)
     Capital  Stock  (other  than  Disqualified   Stock)  of  the  surviving  or
     transferee  Person or (B) cash,  securities or other  property  (other than

     13d-5 under the Exchange Act,  except that a Person shall be deemed to have
     "beneficial  ownership" of all securities that such Person has the right to
     acquire,  whether such right is  exercisable  immediately or only after the
     passage of time),  directly or  indirectly,  of more than a majority of the

     the  beginning  of such period  constituted  the Board of  Directors of the
     Company or Parent  (together with any new directors  whose election to such
     Board of Directors, or whose nomination for election by the stockholders of
     the Company or Parent,  was approved by a vote of 66-2/3% of the  directors
     then still in office who were either  directors  at the  beginning  of such
     period or whose  election or  nomination  for  election was  previously  so
     approved)  cease for any reason to  constitute  a majority  of the Board of
     Directors of the Company or Parent then in office; or

                                       62

<PAGE>

               (iv) the Company is  liquidated  or dissolved or adopts a plan of

SECTION X.18   DESIGNATION OF UNRESTRICTED SUBSIDIARIES

          (1) The Board of Directors of the Company may designate any Subsidiary
(including any newly acquired or newly formed  Subsidiary) to be an Unrestricted
Subsidiary so long as (i) neither the Company nor any  Restricted  Subsidiary is
directly or indirectly  liable for any Debt of such Subsidiary,  (ii) no default
with respect to any Debt of such Subsidiary would permit (upon notice,  lapse of
time or otherwise) any holder of any other Debt of the Company or any Restricted
Subsidiary to declare a default on such other Debt or cause the payment  thereof
to be accelerated or payable prior to its stated maturity,  (iii) any Investment
in  such  Subsidiary  made  as  a  result  of  designating  such  Subsidiary  an
Unrestricted  Subsidiary will not violate the provisions of Section 10.09,  (iv)
neither the Company nor any  Restricted  Subsidiary  has a contract,  agreement,
arrangement,  understanding or obligation of any kind,  whether written or oral,
with such  Subsidiary  on terms  other than those that might be  obtained at the
time from  Persons  who are not  Affiliates  of the  Company and (v) neither the
Company nor any  Restricted  Subsidiary  has any  obligation  to  subscribe  for
additional  shares of Capital Stock or other equity interest in such Subsidiary,
or to maintain or preserve  such  Subsidiary's  financial  condition or to cause
such Subsidiary to achieve certain levels of operating results.  Notwithstanding
the foregoing,  the Company may not designate as an Unrestricted  Subsidiary any
Subsidiary  which, on the date of this Indenture,  is a Significant  Subsidiary,
and may not sell,  transfer or otherwise  dispose of any properties or assets of
any such Significant Subsidiary to an Unrestricted Subsidiary, other than in the
ordinary course of business.

          (2)  The  Board  of  Directors  of  the  Company  may   designate  any
Unrestricted   Subsidiary  as  a  Restricted  Subsidiary;   provided  that  such
designation  will  be  deemed  to be  an  Incurrence  of  Debt  by a  Restricted
Subsidiary of any  outstanding  Debt of such  Unrestricted  Subsidiary  and such
designation  will only be permitted if (i) such Debt is permitted  under Section
10.08 and (ii) no Default or Event of Default  would be in  existence  following
such designation.

SECTION X.19 WAIVER OF CERTAIN COVENANTS.

          Except as  otherwise  provided  herein,  the  Company  may omit in any
particular  instance  to comply  with any  covenant  or  condition  set forth in
Sections 10.04, to 10.15, inclusive,  and Sections 10.17 and 10.18 if before the
time for such compliance the Holders of at least a majority in principal  amount
of the Outstanding  Securities shall, by Act of such Holders,  either waive such
compliance in such instance or generally waive  compliance with such covenant or

                                       65
<PAGE>

condition,  but no such  waiver  shall  extend to or  affect  such  covenant  or
condition except to the extent so expressly waived, and, until such waiver shall
become  effective,  the obligations of the Company and the duties of the Trustee
in respect of any such  covenant  or  condition  shall  remain in full force and
effect.

SECTION X.20 PAYMENT FOR CONSENT.

          Neither  the  Company nor any of its  Subsidiaries  will,  directly or
indirectly,  pay or  cause  to be  paid  any  consideration,  whether  by way of
interest,  fee or  otherwise,  to any  Holder  of  any  Securities  for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities  unless such  consideration is offered to be
paid or is paid to all Holders of  Securities  that  consent,  waive or agree to
amend in the time  period set forth in the  solicitation  documents  relating to
such consent, waiver or agreement.

SECTION X.21   FURTHER INSTRUMENTS AND ACTS

          From  time to time  the  Company  will,  at its own  expense  and upon
request  of the  Trustee,  execute  and  deliver  or  cause to be  executed  and
delivered such further instruments and do such further acts as may reasonably be
necessary or desirable to carry out the purposes of this  Indenture or to secure
the rights and remedies hereunder of the Holders.

SECTION X.22   SUBSIDIARY GUARANTEES

          The Company  will not (i) permit any of its  Restricted  Subsidiaries,
directly or indirectly, to Guarantee or secure through the granting of Liens the
payment of any Debt of the Company (other than Debt under or with respect to the
Bank Credit  Facilities and Permitted  Liens in respect  thereof) or (ii) pledge
any  intercompany  notes  representing  obligations  of any  of  its  Restricted
Subsidiaries  to secure the payment of any Debt of the Company  (other than Debt
under or with  respect to the Bank  Credit  Facilities  and  Permitted  Liens in
respect thereof),  unless such Subsidiary (A) executes a supplemental  indenture
evidencing  its  Guarantee of the  Securities or (B) in the case of a grant of a
security  interest or the pledge of an  intercompany  note in a situation  which
does not comply with clause (A) above,  the holders of the Securities  receive a
security  interest in the asset to which such security  interest relates or such
intercompany  note;  provided,  however,  that this  provision will not apply to
Guarantees  of, or Liens granted to secure,  the USAM Notes which  Guarantees or
Liens are required to be granted  solely and as a direct  result of the granting
of Guarantees or Liens with respect to the Bank Credit Facilities.

                ----                         ----------------

Damages,  if any,  to but  excluding  the  date of  redemption;  provided  that,
immediately after giving effect to such redemption, Securities with an aggregate

SECTION XI.2   APPLICABILITY OF ARTICLE

          Redemption  of Securities at the election of the Company or otherwise,
as permitted or required by any  provision of this  Indenture,  shall be made in

SECTION XI.3   ELECTION TO REDEEM; NOTICE TO TRUSTEE

          The  election  of the  Company to redeem any  Securities  pursuant  to
Section  11.01  shall  be  evidenced  by a  Board  Resolution.  In  case  of any
redemption  at the election of the Company of the  Outstanding  Securities,  the
Company  shall,  at least  60 days  prior to the  Redemption  Date  fixed by the
Company (unless a shorter notice shall be  satisfactory to the Trustee),  notify
the Trustee in writing of such  Redemption  Date and of the principal  amount of
Securities to be redeemed.

SECTION XI.4   SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED

          If less than all of the  Securities  are to be  redeemed  at any time,
selection of Securities for redemption will be made by the Trustee in compliance
with the requirements of the principal national securities exchange,  if any, on
which the Securities are listed,  or, if the Securities are not so listed,  on a
pro rata  basis,  by lot or by such  method as the  Trustee  shall deem fair and
appropriate;  provided  that no Securities  of $1,000  principal  amount or less
shall be redeemed in part.

          The  Trustee  shall  promptly  notify the  Company  and each  Security
Registrar in writing of the Securities  selected for redemption and, in the case
of any Securities selected for partial redemption,  the principal amount thereof
to be redeemed.

                                       67
<PAGE>

          For all  purposes  of this  Indenture,  unless the  context  otherwise
requires,  all provisions relating to the redemption of Securities shall relate,
in the case of any  Securities  redeemed or to be redeemed  only in part, to the
portion of the principal  amount of such  Securities  which has been or is to be
redeemed.

SECTION XI.5   NOTICE OF REDEMPTION

          Notice  of  redemption  shall be given by  first-class  mail,  postage
prepaid,  mailed not less than 30 nor more than 60 days prior to the  Redemption
Date, to each Holder of Securities to be redeemed,  at his address  appearing in
the Security Register.

          All notices of redemption shall identify the Securities to be redeemed
(including CUSIP Numbers) and shall state:

               (1) the Redemption Date,

               (2) the Redemption Price,

               (3)  if  less  than  all  the  Outstanding  Securities  are to be
     redeemed, the identification (and, in the case of partial redemption of any
     Securities,  the  principal  amounts) of the  particular  Securities  to be
     redeemed,

               (4) that on the Redemption Date the Redemption  Price will become
     due and payable upon each such Security to be redeemed and that, unless the
     Company  defaults  on the payment of the  Redemption  Price,  interest  and
     Liquidated  Damages, if any, thereon will cease to accrue on and after said
     date, and

               (5)  the  place  or  places  where  such  Securities  are  to  be
     surrendered for payment of the Redemption Price.

          Notice of  redemption  of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's  request,  by the
Trustee in the name and at the expense of the Company; provided that the Company
has given the Trustee written notice of the Redemption Date and Redemption Price
at least 15 days prior to the date that such notice of redemption  must be given
to the Holders.

SECTION XI.6   DEPOSIT OF REDEMPTION PRICE

          One  Business  Day prior to any  Redemption  Date,  the Company  shall
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent,  segregate and hold in trust as provided in Section 10.03)
an amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest  Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

SECTION XI.7   SECURITIES PAYABLE ON REDEMPTION DATE

                                       68
<PAGE>

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed  shall,  on the  Redemption  Date,  become due and payable at the
Redemption  Price  therein  specified,  and from and after such date (unless the
Company  shall  default  in the  payment  of the  Redemption  Price and  accrued
interest) such  Securities  shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption  Price,  together with accrued interest
to the Redemption Date: provided,  however,  that installments of interest whose
Stated  Maturity is on or prior to the  Redemption  Date shall be payable to the
Holders of such  Securities,  registered as such at the close of business on the
relevant  Record Dates  according to their terms and the  provisions  of Section
3.07.

          If any  Security  called  for  redemption  shall  not be so paid  upon
surrender  thereof for  redemption,  the principal (and premium,  if any) shall,
until paid,  bear  interest  from the  Redemption  Date at the rate borne by the
Security.

SECTION XI.8   SECURITIES REDEEMED IN PART

          Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company  designated  for that purpose  pursuant to
Section 10.02 (with, if the Company or the Trustee so requires,  due endorsement
by, or a written  instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing),  and the Company shall execute,  and the Trustee shall authenticate
and  deliver  to the  Holder of such  Security,  without  service  charge to the
Holder,  a new  Security  or  Securities,  of  any  authorized  denomination  as
requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

Twelve.

discharged its  obligations  with respect to the  Outstanding  Securities on the

For this purpose, such defeasance means that the Company shall be deemed to have
paid and discharged the entire Debt  represented by the  Outstanding  Securities
and to have satisfied all its other  obligations  under such Securities and this
Indenture  insofar as such  Securities  are concerned  (and the Trustee,  at the
expense of the Company,  shall  execute  proper  instruments  acknowledging  the
same),  except for the following which shall survive until otherwise  terminated
or discharged hereunder:  (A) the rights of Holders of Outstanding Securities to
receive, solely from the trust fund described in Section 12.04 and as more fully
set forth in such Section,  payments in respect of the principal of (and premium
and  Liquidated  Damages,  if any) and  interest  on such  Securities  when such
payments are due, (B) the Company's  obligations with respect to such Securities
under Sections 2.02,  3.05,  10.02 and 10.03,  (C) the rights,  powers,  trusts,

          Upon the  Company's  exercise of the option  provided in Section 12.01
applicable  to  this  Section,  (i) the  Company  shall  be  released  from  its
obligations  under  Sections  10.05 through 10.15  inclusive,  Section 10.17 and
Section 10.18,  and (ii) the occurrence of an event specified in Section 501(c),

deemed to be an Event of Default, on and after the date the conditions set forth

covenant  defeasance  means that the  Company  may omit to comply with and shall
have no liability in respect of any term,  condition or limitation  set forth in
any such Section or Article,  whether  directly or  indirectly  by reason of any
reference  elsewhere  herein to any such  Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in any
other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

12.02 or Section 12.03 to the Outstanding Securities:

satisfying the  requirements  of Section 6.09 who shall agree to comply with the
provisions  of this Article  Twelve  applicable  to it) as trust funds in trust,
specifically  pledged as security for, and  dedicated  solely to, the benefit of
the Holders of such Securities,  (A) money in an amount, or (B) U.S.  Government
Obligations  which  through the  scheduled  payment of principal and interest in
respect thereof will provide money in an amount,  or (C) a combination  thereof,
sufficient, in the opinion of a nationally recognized firm of independent public

                                       70
<PAGE>

redemption, if applicable),  of such principal or installment of interest on the
day on which such payments are due and payable in  accordance  with the terms of
this  Indenture  and of such  Securities.  For this  purpose,  "U.S.  Government
Obligations"  means direct  obligations of,  obligations fully guaranteed by, or
participations in pools consisting solely of obligations of or obligations fully
guaranteed  by, the United States of America for the payment of which  guarantee
or  obligations  the full faith and  credit of the  United  States of America is
pledged  and which are not  callable or  redeemable  at the option of the isuuer
thereof.

          (ii) No Event  of  Default  or  Default  shall  have  occurred  and be
continuing on the date of such deposit or,  insofar as  subsections  5.01(h) and

the date of such deposit (it being  understood  that this condition shall not be
deemed satisfied until the expiration of such period).

          (iii)  Such  defeasance  or  covenant  defeasance  shall not cause the
Trustee  (or  such  other  qualifying  trustee,  if any)  to have a  conflicting
interest as defined in Section 6.08 and for purposes of the Trust  Indenture Act
with respect to any securities of the Company.

          (iv) Such defeasance or covenant  defeasance shall not (x) result in a
breach or violation of, or constitute a default under, any material agreement or
instrument  to which the Company is a party or by which it is bound or (y) cause
the Trustee (or such other qualifying  trustee,  if any) or the trust so created
to be subject to the Investment Company Act of 1940.

          (v) In the case of defeasance, the Company shall have delivered to the
Trustee (and such other qualifying trustee, if any) an Officers' Certificate and
an Opinion of Counsel,  each stating that all conditions  precedent provided for
relating to either the defeasance under Section 12.02 or the covenant defeasance
under Section 12.03 (as the case may be) have been complied with.

          (vi) In the case of an election under Section 12.02, the Company shall
have  delivered to the Trustee (and such other  qualifying  trustee,  if any) an
Opinion of Counsel  stating  that (x) the Company has received a ruling from the
Internal  Revenue Service or (y) since the date of this Indenture there has been
a change in the applicable Federal income tax law or there has been published by
the Internal  Revenue Service a document that may be used or cited as precedent,
in either case (x) or (y) to the effect  that,  and based  thereon  such opinion
shall confirm that, the Holders of the Outstanding Securities will not recognize
income,  gain or loss for  Federal  income  tax  purposes  as a  result  of such
defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance
had not occurred.

          (vii) In the case of an  election  under  Section  12.03,  the Company
shall have delivered to the Trustee (and such other qualifying  trustee, if any)
an  Opinion  of  Counsel  to the  effect  that the  Holders  of the  outstanding
securities  will not  recognize  income,  gain or loss for  Federal  income  tax
purposes as a result of such deposit and covenant defeasance and will be subject
to Federal  income tax on the same  amounts,  in the same manner and at the same
times as would have been the case if such  deposit and covenant  defeasance  had
not occurred.

SECTION XII.5  DEPOSITED  MONEY AND  GOVERNMENT  SECURITIES TO BE HELD IN TRUST;
               OTHER MISCELLANEOUS PROVISIONS

          Subject to the provisions of the last paragraph of Section 10.03,  all
money and Government  Securities (including the proceeds thereof) deposited with
the Trustee (or other qualifying  trustee -- collectively,  for purposes of this
Section  12.05 and Section  12.06,  the  Trustee")  pursuant to Section 12.04 in
respect of the Securities shall be held in trust and applied by the Trustee,  in
accordance  with the provisions of such  Securities and this  Indenture,  to the
payment,  either  directly or through any Paying  Agent  (including  the Company
acting as its own Paying Agent) as the Trustee may determine,  to the Holders of
such  Securities,  of all sums due and to  become  due  thereon  in  respect  of
principal (and premium,  and Liquidated Damages, if any) and interest,  but such
money need not be segregated  from other funds except to the extent  required by
law.

          The Company shall pay and  indemnify the Trustee  against any tax, fee
or other  charge  imposed  on or  assessed  against  the  Government  Securities
deposited  pursuant to Section 12.04 or the  principal and interest  received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

          Anything in this Article Twelve to the contrary  notwithstanding,  the
Trustee  shall  deliver  or pay to the  Company  from time to time upon  Company
Request  any money or  Government  Securities  held by it as provided in Section
12.04  which,  in the opinion of a  nationally  recognized  firm of  independent
public accountants expressed in a written certification thereof delivered to the
Trustee,  are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent defeasance or covenant defeasance.

SECTION XII.6  REINSTATEMENT

          If the  Trustee  or the  Paying  Agent is unable to apply any money in
accordance with Section 12.02 or 12.03 by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such  application,  then the Company's  obligations under this Indenture and the
Securities  shall be revived and  reinstated  as though no deposit had  occurred
pursuant to this  Article  Twelve until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance  with Section 12.02 or 12.03;
provided,  however,  that if the Company  makes any payment of principal of (and
premium,  and Liquidated  Damages, if any) or interest on any Security following
the  reinstatement  of its  obligations,  the Company shall be subrogated to the
rights of the Holders of such  Securities to receive such payment from the money
held by the Trustee or the Paying Agent.


          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original,  but all such  counterparts
shall together constitute but one and the same instrument.

                         ARCH COMMUNICATIONS GROUP, INC.

                         Pursuant to Section 151 of the
                        Delaware General Corporation Law

     Arch Communications Group, Inc., a Delaware corporation (the "Corporation),
pursuant  to  Section  151(g)  of the  General  Corporation  Law of the State of
Delaware,  files this  Certificate  of  Designations  setting  forth a copy of a
resolution  duly  adopted by the Board of Directors  of the  Corporation,  which
resolution  remains in full force and effect as of the date hereof, to establish
the voting powers, designations, preferences and rights of 250,000 shares of the
authorized  Preferred Stock of the Corporation  pursuant to authority  expressly
vested in the Board of Directors by Article  Fourth of the Restated  Certificate
of Incorporation of the Corporation:

          WHEREAS,  the Board of Directors  of the  Corporation  is  authorized,
     within the limitations and restrictions stated in the Restated  Certificate
     of  Incorporation,  to fix by resolution or resolutions  the designation of
     one or more series of the  Corporation's  Preferred Stock,  $0.01 par value
     per  share,  and  the  powers,  preferences  and  relative,  participating,
     optional  or  other  special  rights  and  qualifications,  limitations  or
     restrictions  thereof,  including,  without  limiting the generality of the
     foregoing, such provisions as may be desired concerning voting, redemption,

     exchange,  and other  subjects or matters as may be fixed by  resolution or

          WHEREAS,   it  is  the  desire  of  the  Board  of  Directors  of  the
     Corporation,  pursuant to its authority as aforesaid,  to authorize and fix
     the  terms  of a  series  of  preferred  stock  and the  number  of  shares
     constituting such series;

          NOW, THEREFORE, BE IT

          RESOLVED,  that the Board of  Directors  does  create,  authorize  and
     provide for the issuance of a series of the Corporation's  Preferred Stock,
     $0.01 par value per share,  consisting of 250,000  shares of the authorized
     Preferred Stock of the Corporation,  with the voting powers,  designations,
     preferences and rights specified below:

                                      -1-
<PAGE>

     Section 1. DESIGNATIONS. Two hundred fifty thousand (250,000) shares of the
Corporation's  Preferred  Stock  shall be  designated  as "Series C  Convertible
Preferred  Stock."  The Series C  Convertible  Preferred  Stock  (the  "Series C
Preferred  Stock") shall sometimes be referred to herein with the  Corporation's
existing  Series A Preferred Stock and Series B Junior  Participating  Preferred
Stock, collectively, as the "Preferred Stock."


     Section 2. DIVIDENDS.

          (a)  PRIORITY  OF  DIVIDENDS.  Subject  to the  rights  of  series  of
authorized Preferred Stock which may from time to time come into existence after
the  date  hereof,  no  dividends  shall  be  declared  or  set  aside  for  the
Corporation's  Common Stock, par value $0.01 per share (the "Common Stock"),  or
any class or  series of  securities  junior  in rank to the  Series C  Preferred
Stock,  including the Corporation's existing Series A Preferred Stock and Series
B Junior  Participating  Preferred  Stock  (together with the Common Stock,  the
"Junior  Stock"),  unless prior thereto all accrued and unpaid  dividends on the
Series C  Preferred  Stock shall be  declared,  set aside and paid on all of the
then  outstanding  shares of Series C Preferred  Stock. In the event that, after
declaration  of a cash dividend on the Series C Preferred  Stock,  funds legally
available for  distribution on any Dividend  Payment Date (as defined in Section
2(b)) are  insufficient  to fully pay the cash  dividend due and payable on such
Dividend  Payment Date to all holders of outstanding  Series C Preferred  Stock,
then all  funds  legally  available  for  distribution  shall be paid in cash to
holders of Series C Preferred  Stock in accordance  with the number of shares of
Series C Preferred Stock held by each such holder. Any remaining dividend amount
owed to holders of the Series C Preferred  Stock shall be accrued in  accordance
with Section 2(b).  Alternatively,  at the Corporation's option, dividends shall
be payable in the form of the Stock Dividend (as defined in Section 2(b)).

     The Corporation shall not declare or pay any dividends or distributions on,
or redeem,  repurchase,  accept or  otherwise  acquire for value,  any shares of
Junior Stock or any class or series of securities  equal in rank to the Series C
Preferred Stock ("Parity Stock")  hereinafter  issued by the Corporation (any of
the foregoing,  a "Restricted  Payment") if all accrued and unpaid  dividends on
all the then  outstanding  shares of Series C Preferred Stock have not been paid
in full, unless the Corporation shall have first offered,  and provided evidence
of its ability to pay, in cash,  to the holders of the Series C Preferred  Stock
all such dividends on the Series C Preferred Stock. The holders of a majority of
the then  outstanding  shares of Series C  Preferred  Stock may accept or reject
such offer in their sole  discretion,  which  decision shall be binding upon all
holders of Series C Preferred.  If such offer is made, the  Corporation may make
such Restricted  Payment,  and in the case of any Restricted Payment in the form
of a dividend or  distribution  payable with respect to shares of Common  Stock,
the  holders of the  outstanding  Series C Preferred  Stock  shall be  entitled,
ratably in  proportion  to the shares of Common  Stock into which such  Series C

                                      -2-
<PAGE>

Preferred Stock could then be converted,  to participate  therein (to the extent
the holders of Common Stock have a right to  participate in any such dividend or
distribution).  Notwithstanding  the  foregoing,  the  foregoing  provisions  of
Section  2(a) shall not apply in the event the  Corporation  shall  dividend  or
otherwise distribute rights to all holders of Common Stock entitling the holders
thereof to subscribe for or purchase shares of capital stock of the Corporation,
which rights (i) until the occurrence of a specified  event or events are deemed
to be transferred  with such shares of Common Stock and are not  exercisable and
(ii) are issued in respect of future  issuances of Common Stock  ("Rights").  In
such event,  the holders of shares of Series C Preferred Stock shall be entitled
to receive any such Rights  ratably in  proportion to the shares of Common Stock
into which such Series C Preferred  Stock could be  converted  or shall  receive
such Rights upon any  conversion of the Series C Preferred  Stock into shares of
Common Stock no later than the date such Rights  separate  from the Common Stock
or otherwise become exercisable (the  "Distribution  Date"), in each case to the
extent such Rights have not been redeemed, terminated or otherwise have expired.

          (b) DIVIDEND RATE; FORM OF DIVIDEND  PAYMENT;  DIVIDEND PAYMENT DATES.
Each holder of the Series C Preferred  Stock shall be entitled to receive  when,
as and if declared by the Board of  Directors,  out of funds  legally  available
therefor,  cumulative cash dividends, in preference and priority to dividends on
any Junior  Stock,  that shall  accrue on the  Liquidation  Price (as defined in
Section 3(a)) of each share of the Series C Preferred Stock at the rate of eight
percent (8%) per annum,  from and including the date on which Series C Preferred
Stock was first issued (the "Original  Issue Date") to and including the date on
which the Liquidation  Price of such share is paid in full to the holder of such
share pursuant to Section 3. At the  Corporation's  option, so long as shares of
the Common  Stock  remain  listed on the Nasdaq  National  Market  ("NNM") (or a
national  securities  exchange  where  the  Common  Stock  may then be  listed),
dividends may be paid in fully registered,  fully paid and nonassessable  shares
of the Common  Stock  with a value  equal to the  dividend  amount  (the  "Stock
Dividend").  As used  herein,  "fully  registered"  shares of  Common  Stock may
include shares of Common Stock with respect to which the Corporation has filed a
registration  statement  with the  Securities  and Exchange  Commission  for the
resale of such shares by the holders  thereof and which  registration  statement
remains  effective and as to which such holders would  otherwise be permitted to
effect the resale of such shares under  applicable  federal and state securities
laws. For purposes of payment,  the value of the Common Stock shall be deemed to
be equal to 95% of the Market  Price (as  hereinafter  defined) for the ten (10)
trading days immediately  preceding the corresponding  Dividend Payment Date (as
hereinafter  defined).  If any  fractional  share of the Common  Stock  would be
issuable  in payment  of any  dividend  on any share of the  Series C  Preferred
Stock,  the  Corporation  shall  make a cash  payment  for such  portion  of the
dividend  in  lieu  of  fractional  shares  of the  Common  Stock.  The  accrued
dividends,  in either form, will be adjusted for stock splits,  stock dividends,
recapitalizations, reclassifications and similar events (together referred to as
"Recapitalization  Events") which affect the number of outstanding shares of the

                                      -3-
<PAGE>

Series C Preferred  Stock.  Accrued  dividends  on the Series C Preferred  Stock
shall be payable out of funds legally  available  therefor on March 31, June 30,
September  30 and  December  31 of each year (each a "Dividend  Payment  Date"),
commencing  on  September  30,  1998,  to the  holders of record of the Series C
Preferred  Stock as of the close of  business  on the  applicable  record  date.
Dividends shall be fully cumulative and shall accrue on a daily basis based on a
365- day or 366-day year, as the case may be,  without  regard to the occurrence
of a Dividend  Payment Date and whether or not such dividends have been declared
and whether or not there are any unrestricted  funds of the Corporation  legally
available for the payment of dividends.  The amount of dividends  "accrued" with
respect  to any  share of  Series C  Preferred  Stock as of the  first  Dividend
Payment  Date after the Original  Issue Date,  or as of any other date after the
Original Issue Date that is not a Dividend  Payment Date, shall be calculated on
the basis of the actual  number of days elapsed from and  including the Original
Issue  Date,  in the case of the  first  Dividend  Payment  Date and any date of
determination  prior to the first  Dividend  Payment Date, or from and including
the last  preceding  Dividend  Payment  Date,  in the case of any other  date of
determination,  to and including such date of determination which is to be made,
in  each  case  based  on a year of 365 or 366  days,  as the  case  may be (the
"Dividend Period").  Whenever the Board of Directors of the Corporation declares
any dividend  pursuant to this Section 2, notice of the  applicable  record date
and related Dividend Payment Date shall be given.

          As used  herein,  the "Market  Price" of the Common  Stock at any date
shall  mean the  closing  price  per  share of  Common  Stock on such  date,  as
officially  reported by NNM or such other national securities exchange where the
Common  Stock may then be listed,  and,  when used with  reference  to shares of
Common Stock for any period shall mean the average of the daily  closing  prices
per share of Common Stock for such period.  The closing price for each day shall
be the last quoted sale price or, if not so quoted,  the average of the high bid
and low asked prices in the over-the-counter market, as reported by the National
Association of Securities Dealers, Inc. Automated Quotation System or such other
system then in use.

          (c) COMPOUNDING OF DIVIDENDS;  ADDITION TO LIQUIDATION  PRICE. On each
Dividend Payment Date, all dividends that have accrued on each share of Series C
Preferred Stock during the immediately  preceding  Dividend Period shall, to the
extent not paid on such  Dividend  Payment  Date for any reason  (whether or not
such unpaid dividends have been earned or declared or there are any unrestricted
funds of the  Corporation  legally  available for the payment of dividends),  be
added to the  Liquidation  Price of such  share  effective  as of such  Dividend
Payment Date and shall remain a part thereof to and  including the date on which
the Liquidation  Price of such share is paid in full to the holder of such share
pursuant to Section 3.

                                      -4-
<PAGE>


          (d) PRO RATA DECLARATION AND PAYMENT OF DIVIDENDS.  All dividends paid
with respect to shares of the Series C Preferred  Stock pursuant to this Section
2 shall be declared and paid PRO RATA to all the holders of the shares of Series
C Preferred Stock outstanding as of the applicable record date.

     Section 3. LIQUIDATION, DISSOLUTION OR WINDING UP.

          (a)  In  the  event  of  any  voluntary  or  involuntary  liquidation,
dissolution or winding up of the Corporation,  whether voluntary or involuntary,
(each such event,  a  "Liquidation"),  except as provided in Section 3(b) below,
subject to the rights of series of authorized Preferred Stock that may from time
to time come into  existence,  the holders of shares of Series C Preferred Stock
then outstanding  shall be entitled,  ratably in proportion to the shares of the
Series C Preferred  Stock held by such holders,  to be paid out of the assets of
the Corporation available for distribution to its stockholders before payment to
the holders of Junior Stock, and PARI PASSU with Parity Stock, if any, by reason
of their ownership thereof,  an amount equal to (A) (i) $100.00 per share of the
Series  C  Preferred   Stock   (subject  to   appropriate   adjustment  for  any
Recapitalization  Events), plus (ii) an amount equal to all dividends accrued on
such share of the Series C Preferred Stock since the Original Issue Date thereof
which,  pursuant  to Section  2(c),  have been  added to and remain  part of the
Liquidation Price as of such time of  determination,  whether or not such unpaid
dividends  have been earned or declared or there are any  unrestricted  funds of
the Corporation  legally  available for the payment of dividends,  plus (iii) an
amount  equal to all accrued and unpaid  dividends  accrued on such share of the
Series C  Preferred  Stock  during the  period  from the  immediately  preceding
Dividend  Payment  Date  through  and  including  the  determination  date  (the
"Liquidation Price").

          (b)  If  upon  any  such  Liquidation  the  remaining  assets  of  the
Corporation available for distribution to its stockholders shall be insufficient
to pay the  holders  of shares of Series C  Preferred  Stock the full  amount to
which they shall be entitled, then the entire assets of the Corporation shall be
distributed  among the holders of shares of Series C Preferred  Stock ratably in
proportion to the shares of Series C Preferred Stock held by such holders.

          (c) After the payment of all preferential  amounts required to be paid
to the  holders  of  Series  C  Preferred  Stock,  upon the  Liquidation  of the
Corporation,  the holders of shares of Junior  Stock then  outstanding  shall be
entitled to receive the remaining assets and funds of the Corporation  available
for distribution to its stockholders.

     Section 4. VOTING RIGHTS.

          (a) The holder of each share of Series C  Preferred  Stock  shall have
the right to one vote for each share of Common  Stock  into which such  Series C

                                      -5-
<PAGE>

Preferred  Stock could then be  converted,  and with respect to such vote,  such
holder shall have full voting  rights and powers equal to the voting  rights and
powers of the holders of Common Stock and shall be entitled, notwithstanding any
provision hereof, to notice of any stockholders'  meeting in accordance with the
bylaws of the Corporation  and shall be entitled to vote,  together with holders
of Common  Stock,  with respect to any  questions  upon which  holders of Common
Stock have the right to vote. Notwithstanding the foregoing, with respect to the
election  of  directors,  so long as at  least  50% of the  shares  of  Series C
Preferred Stock issued as of the Original Issue Date (as appropriately  adjusted
for  Recapitalization  Events)  are  outstanding,  the  holders  of the Series C
Preferred   Stock,   voting  as  a  separate   class  (and  without  the  voting
participation  of holders of other shares of capital  stock of the  Corporation)
shall be  entitled  to elect one member of the Board of  Directors.  Such member
shall have the right to be a member of any committee of the Corporation's  Board
of Directors.

          (b)  Subject to the  rights of series of  authorized  Preferred  Stock
which may from time to time come into existence, so long as any shares of Series
C Preferred  Stock are  outstanding,  the  Corporation  shall not without  first
obtaining the approval (by vote or written  consent,  as provided by law) of the
holders  of a  majority  of the then  outstanding  shares of Series C  Preferred
Stock, voting together as a single class:

               (i) authorize,  increase the  authorized  number of shares of, or
issue,  any  shares of any class or series of capital  stock of the  Corporation
ranking prior to or, so long as at least 50% of the shares of Series C Preferred
Stock  issued as of the  Original  Issue  Date (as  appropriately  adjusted  for
Recapitalization  Events)  remain  outstanding,  on a parity  with the  Series C
Preferred Stock;

               (ii)  increase the  authorized  number of shares of, or issue any
shares of Series C Preferred Stock;

               (iii)  authorize,  adopt or approve an  amendment to the Restated
Certificate  of  Incorporation  of the  Corporation  which  would  decrease  the
aggregate  number of  authorized  shares of Series C  Preferred  Stock below the
number then outstanding,  or alter or change the powers,  preferences or special
rights of the shares of Series C Preferred  Stock so as to affect such shares of
Series C Preferred Stock adversely; or

               (iv) reclassify any shares of Common Stock or any other shares of
any class or series of capital stock of the Company into shares ranking prior to
or, so long as at least 50% of the shares of Series C Preferred  Stock issued as
of the  Original  Issue Date (as  appropriately  adjusted  for  Recapitalization
Events) remain outstanding, on a parity with the Series C Preferred Stock.

                                      -6-
<PAGE>

          (c) In addition to the matters described in Section 4(b) above, at any
time prior to the third  anniversary of the Original Issue Date, the Corporation
shall not  participate in any merger or  consolidation  in which its outstanding
securities are converted into securities, cash or other property, or sell all or
substantially all of its assets (each of the foregoing, a "Transaction") without
the prior written consent or affirmative  vote of  stockholders  representing at
least a majority  of the then  outstanding  shares of Series C  Preferred  Stock
voting as a single class; provided,  however, that such prior written consent or
affirmative vote of stockholders  representing such shares of Series C Preferred
Stock shall not be required if the conditions in any of the following paragraphs
(i), (ii) or (iii) below are satisfied:

          (i) In  the  event  that  at  least  50% of  the  total  value  of the
consideration being issued or paid to the Corporation or its stockholders in the
Transaction  consists of cash (as determined in good faith by the  Corporation's
Board of  Directors),  the  consideration  payable  to each  holder  of Series C
Preferred Stock in connection with such Transaction,  either (A) with respect to
(and in cancellation of) each share of Series C Preferred Stock or (B) on an "as
converted"  basis  with  respect to the Common  Stock  underlying  such share of
Series C Preferred  Stock,  shall be an amount that is not less than the greater
of (i) $150.00 or (ii) an amount  sufficient to result in a compounded  internal
rate of return of at least 30% (as measured from the Original  Issue Date on the
basis of an  initial  investment  of  $100.00  per share of  Series C  Preferred
Stock); provided, however, that the foregoing condition is not intended to limit
the amount  that such  holder of Series C Preferred  Stock  would  otherwise  be
entitled  to  receive  on an  "as  converted"  basis  in  connection  with  such
Transaction.

          (ii) In the  event  that  less  than  50% of the  total  value  of the
consideration being issued or paid to the Corporation or its stockholders in the
Transaction  consists of cash (as determined in good faith by the  Corporation's
Board of  Directors),  (A) the Series C Preferred  Stock shall be assumed by the
surviving  entity or transferee  entity (the  "Successor") and (B) the Successor
shall have and maintain a ratio of total consolidated debt (including  preferred
stock) to total consolidated  operating cash flow (last quarter annualized) that
shall not  exceed  6.5:1 (as  determined  in good  faith by the Chief  Financial
Officer  of  the  Successor  using  generally  accepted  accounting   principles
consistently applied).

          (iii) In the event  that the  conditions  specified  in the  foregoing
paragraphs  (i) or (ii),  as  applicable,  are not  satisfied  with respect to a
particular  Transaction,  the  Corporation  has  offered,  at its  election,  to
redeem/convert  the Series C Preferred  Stock by paying or causing to be paid to
each holder of Series C Preferred Stock,  concurrently  with the consummation of
such Transaction, an amount payable in cash with respect to (and in cancellation
of) each share of Series C  Preferred  Stock that is equal to the greater of (i)
$150.00 or (ii) an amount sufficient to result in a compounded  internal rate of

                                      -7-
<PAGE>

return of at least 30% (as measured from the Original Issue Date on the basis of
an initial investment of $100.00 per share of Series C Preferred Stock).

     Section 5.  CONVERSION.  The holders of the Series C Preferred  Stock shall
have conversion rights as follows (the "Conversion Rights"):

          (a) RIGHT TO CONVERT.  Each  holder of Series C Preferred  Stock shall
have the right to convert each share of Series C Preferred  Stock, at the option
of such holder,  at any time,  into such number of fully paid and  nonassessable
shares of Common Stock as is  determined by dividing the  Liquidation  Price (as
defined in Section 2(a)) by the Conversion  Price (as defined  hereinafter)  per
share in effect at the time of such conversion.

          The Conversion  Price per share for the Series C Preferred Stock shall
initially be $5.50. Such initial Conversion Price shall be subject to adjustment
as hereinafter provided.

          (b)  MANDATORY  CONVERSION.  The  Corporation  shall have the right to
cause the conversion of all of the shares of the Series C Preferred Stock on and
after the third anniversary of the Original Issue Date of the Series C Preferred
Stock  into such  number of fully  paid and  nonassessable  shares of the Common
Stock  as  is  calculable  under  Section  5(a);  PROVIDED,  HOWEVER,  that  the
Corporation may not exercise such conversion  right unless the weighted  average
(by daily trading  volume)  closing price per share of Common Stock for a period
of thirty (30)  consecutive  trading days  immediately  prior to such  mandatory
conversion is greater than 200% of the Conversion  Price.  In no event shall the
Corporation  cause the  conversion  of any Series C Preferred  Stock at any time
prior to the  third  anniversary  of the  Original  Issue  Date of the  Series C
Preferred Stock.

          (c)  MECHANICS OF  CONVERSION.  No  fractional  shares of Common Stock
shall be issued upon conversion of the Series C Preferred  Stock. In lieu of any
fractional share to which a holder would otherwise be entitled,  the Corporation
shall  pay cash  equal to such  fraction  multiplied  by the  Market  Price  (as
hereinafter defined) per share of Common Stock on the date immediately preceding
the  conversion  date.  Before any holder of Series C  Preferred  Stock shall be
entitled  to convert  the same into shares of Common  Stock,  such holder  shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the  Corporation or of any transfer  agent for the Series C Preferred  Stock,
and shall give written  notice to the  Corporation  at its  principal  corporate
office,  of the election to convert the same and shall state therein the name or
names in which the certificate or certificates for shares of Common Stock are to
be issued.  If upon such conversion the holders of Series C Preferred Stock have
received any Rights and such  conversion  takes place prior to the  Distribution
Date with respect to such Rights,  such holder shall also  surrender such Rights
upon such conversion.  The Corporation shall, as soon as practicable thereafter,

                                      -8-
<PAGE>

issue and deliver at such office to such holder of Series C Preferred  Stock, or
to the nominee or nominees of such holder, a certificate or certificates for the
number of shares of Common  Stock to which  such  holder  shall be  entitled  as
aforesaid.  Such conversion shall be deemed to have been made immediately  prior
to the close of business on the date of such surrender of the shares of Series C
Preferred Stock to be converted,  and the person or persons  entitled to receive
the shares of Common Stock  issuable upon such  conversion  shall be treated for
all  purposes as the record  holder or holders of such shares of Common Stock as
of such date. If the conversion is in connection with an  underwritten  offering
of securities registered pursuant to the Securities Act of 1933, as amended, the
conversion may, at the option of any holder  tendering  Series C Preferred Stock
for  conversion,  be conditioned  upon the closing with the  underwriters of the
sale of  securities  pursuant to such  offering,  in which  event the  person(s)
entitled  to receive  Common  Stock upon  conversion  of such Series C Preferred
Stock shall not be deemed to have converted such Series C Preferred  Stock until
immediately prior to the closing of such sale of securities.

          (d) ADJUSTMENTS TO CONVERSION PRICE FOR DILUTING ISSUES.

               (i) SPECIAL  DEFINITIONS.  For  purposes  of this  Section 5, the
following definitions shall apply:

                    (A)  "OPTIONS"  shall mean  rights,  options or  warrants to
subscribe for,  purchase or otherwise acquire either Common Stock or Convertible
Securities.

                    (B)  "CONVERTIBLE  SECURITIES"  shall mean any  evidences of
indebtedness,  shares  (other than Common  Stock and  Preferred  Stock) or other
securities convertible into or exchangeable for Common Stock.

                    (C)  "ADDITIONAL  SHARES OF  COMMON  STOCK"  shall  mean all
shares of Common Stock issued (or, pursuant to paragraph 5(c)(iii), deemed to be
issued) by the Corporation  after the Original Issue Date,  other than shares of
Common Stock issued or issuable:

                         (1) in connection  with the  acquisition of the capital

Stock;

plan or other employee stock incentive  program  (collectively,  the "Plans") or
any  other  agreement  with  any  third  parties  so long as any  such  Plans or
agreements are approved by the Corporation's Board of Directors;

                         (4) as a dividend or distribution on Series C Preferred
Stock;

                         (5) by way of dividend or other  distribution on shares
of Common Stock  excluded from the  definition  of  Additional  Shares of Common
Stock by the  foregoing  clauses  (1),  (2),  (3) and (4) or on shares of Common
Stock so excluded; or

                         (6) by way of  adjustments  made  pursuant  to  Section
5(e).

               (ii) NO  ADJUSTMENT  OF  CONVERSION  PRICE.  No adjustment in the
Conversion  Price of Series C  Preferred  Stock  shall be made in respect of the
issuance of Additional Shares of Common Stock unless the consideration per share
for an  Additional  Share of Common  Stock  issued or deemed to be issued by the
Corporation is less than the Market Price on the date of, and immediately prior,
to such issue.

               (iii) DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON STOCK.

                    (A) OPTIONS  AND  CONVERTIBLE  SECURITIES.  In the event the
Corporation at any time or from time to time after the Original Issue Date shall
issue any Options or  Convertible  Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or  Convertible  Securities,  then the maximum  number of shares (as set
forth in the  instrument  relating  thereto  without  regard  to any  provisions
contained  therein for a subsequent  adjustment  of such number) of Common Stock
issuable  upon the  exercise  of such  Options  or,  in the case of  Convertible
Securities and Options therefor,  the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such a record date shall have been fixed,  as
of the close of business on such record date, provided that Additional Shares of
Common  Stock shall not be deemed to have been issued  unless the  consideration
per share  (determined  pursuant to Section  5(d)(v)  hereof) of such Additional
Shares of Common  Stock  would be less than the Market  Price on the date of and
immediately  prior to such issue,  or such record date,  as the case may be, and
provided  further  that in any such  case in which  Additional  Shares of Common
Stock are deemed to be issued:

                         (1) no further adjustment in the Conversion Price shall
be made upon the subsequent issue of Convertible  Securities or shares of Common

                                      -10-
<PAGE>

Stock upon the  exercise  of such  Options or  conversion  or  exchange  of such
Convertible Securities;

                         (2) if such Options or Convertible  Securities by their
terms  provide,  with the passage of time or otherwise,  for any increase in the
consideration payable to the Corporation, or decrease in the number of shares of
Common Stock issuable,  upon the exercise,  conversion or exchange thereof,  the
Conversion  Price  computed  upon  the  original  issue  thereof  (or  upon  the
occurrence  of  a  record  date  with  respect  thereto),   and  any  subsequent
adjustments  based thereon,  shall,  upon any such increase or decrease becoming
effective,  be  recomputed  to reflect such  increase or decrease  insofar as it
affects  such  Options  or the  rights of  conversion  or  exchange  under  such
Convertible Securities; and

                         (3) on the expiration or cancellation of any Options or
the termination of the right to convert or exchange any  Convertible  Securities
which shall have not been  exercised,  if the  Conversion  Price shall have been
adjusted  upon the  original  issuance  thereof or shall have been  subsequently
adjusted  pursuant to clause (2) above, the Conversion Price shall be recomputed
as if:

                              a)  in  the  case  of  Convertible  Securities  or
Options for Common Stock, the only Additional Shares of Common Stock issued were
shares of Common  Stock,  if any,  actually  issued  upon the  exercise  of such
Options or the conversion or exchange of such  Convertible  Securities,  and the
consideration  received therefor was the consideration  actually received by the
Corporation  for the issue of all such Options,  whether or not exercised,  plus
the consideration  actually  received by the Corporation upon such exercise,  or
for the issue of all such Convertible  Securities which were actually  converted
or exchanged plus the  consideration  actually  received by the Corporation upon
such conversion or exchange, if any, and

                              b)  in  the  case  of  Options   for   Convertible
Securities,  only the Convertible  Securities,  if any, actually issued upon the
exercise  thereof  were  issued  at the time of issue  of such  Options  and the
consideration  received by the Corporation  for the Additional  Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the  Corporation  for the issue of all such Options,  whether or not  exercised,
plus  the  consideration  deemed  to  have  been  received  by  the  Corporation
(determined  pursuant  to  Section  5(d)(v))upon  the  issue of the  Convertible
Securities with respect to which such Options were actually exercised;

                         (4) no readjustment pursuant to clause (2) or (3) above
shall have the effect of  increasing  the  Conversion  Price to an amount  which
exceeds the lower of (i) the Conversion  Price on the original  adjustment date,
or (ii) the  Conversion  Price that would have  resulted  from any  issuance  of
Additional Shares of Common Stock between the original  adjustment date and such
readjustment date.

               (iv)  ADJUSTMENT OF CONVERSION  PRICE UPON ISSUANCE OF ADDITIONAL
SHARES OF COMMON  STOCK.  In the event the  Corporation  shall issue  Additional
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued  pursuant  to  Section   5(d)(iii))   without   consideration  or  for  a
consideration  per  share  less  than  the  Market  Price  on  the  date  of and
immediately prior to such issuance, then and in such event, the Conversion Price
of the  Series C  Preferred  Stock  shall be  reduced,  concurrently  with  such
issuance,  (A) to a price  (calculated  to the nearest full cent)  determined by
multiplying the Conversion  Price by a fraction (x) the numerator of which shall
be the sum of (1) the number of shares of Common Stock  outstanding  immediately
prior to such issuance,  plus (2) the number of shares of Common Stock which the
aggregate  consideration  received by the  Corporation  for the total  number of
Additional  Shares of Common  Stock so issued would  purchase at the  Conversion
Price;  and (y) the  denominator  of which  shall be (1) the number of shares of
Common Stock outstanding immediately prior to such issue, plus (2) the number of
such Additional Shares of Common Stock so issued; and provided further that, for
the purposes of this Section 5(d)(iv),  all shares of Common Stock issuable upon
(i)  conversion  of all  outstanding  Preferred  Stock,  (ii)  conversion of all
outstanding  Convertible  Securities and (iii) upon exercise of all  outstanding
Options, shall be deemed to be outstanding, and immediately after any Additional
Shares of Common Stock are deemed  issued  pursuant to Section  5(c)(iii),  such
Additional Shares of Common Stock shall be deemed to be outstanding.

               (v) DETERMINATION OF CONSIDERATION.  For purposes of this Section
5(c),  the  consideration  received  by the  Corporation  for the  issue  of any
Additional Shares of Common Stock shall be computed as follows:

                    (A) CASH AND PROPERTY. Such consideration shall:

                         (1) insofar as it consists of cash,  be computed as the
aggregate amount of cash received by the Corporation;

                         (2) insofar as it consists of property other than cash,
be computed at the fair value  thereof at the time of such issue,  as determined
in good faith by the Board of Directors; and

                         (3) in the event Additional  Shares of Common Stock are
issued  together  with  other  shares  or  securities  or  other  assets  of the
Corporation  for  consideration  which covers both,  be the  proportion  of such
consideration so received, computed as provided in clauses (1) and (2) above, as
determined in good faith by the Board of Directors.

                                      -12-
<PAGE>


                    (B) OPTIONS AND CONVERTIBLE  SECURITIES.  The  consideration
per share  received by the  Corporation  for  Additional  Shares of Common Stock
deemed to have been issued  pursuant to Section  5(c)(iii),  relating to Options
and Convertible Securities, shall be determined by dividing

                         (x) the total amount, if any, received or receivable by
the  Corporation as  consideration  for the issue of such Options or Convertible
Securities,  plus the minimum  aggregate amount of additional  consideration (as
set forth in the instruments  relating thereto,  without regard to any provision
contained therein for a subsequent adjustment of such consideration)  payable to
the Corporation  upon the exercise of such Options or the conversion or exchange
of such  Convertible  Securities,  or in the  case of  Options  for  Convertible
Securities,  the exercise of such  Options for  Convertible  Securities  and the
conversion or exchange of such Convertible Securities by

                         (y) the  maximum  number of shares of Common  Stock (as
set forth in the instruments  relating thereto,  without regard to any provision
contained therein for a subsequent  adjustment of such number) issuable upon the
exercise of such  Options or the  conversion  or  exchange  of such  Convertible
Securities.

          (e) ADJUSTMENTS  FOR STOCK  DIVIDENDS,  SUBDIVISIONS,  COMBINATIONS OR
CONSOLIDATIONS.  In the event the Corporation  shall pay a stock dividend on the
Common Stock,  or the  outstanding  shares of Common Stock shall be  subdivided,
combined or consolidated, by reclassification,  stock split or otherwise, into a
greater or lesser number of shares of Common Stock, the Conversion Price for the
Series  C  Preferred  Stock  in  effect  immediately  prior  to  such  dividend,
subdivision,   combination  or  consolidation   shall,   concurrently  with  the
effectiveness of such dividend,  subdivision,  combination or consolidation,  be
proportionately adjusted.

          (f) NO  IMPAIRMENT.  The  Corporation  will not, by  amendment  of its
Restated Certificate of Incorporation or through any reorganization, transfer of
assets, merger, dissolution,  issue or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
to be observed or performed  hereunder by the  Corporation but will at all times
in good faith assist in the carrying out of all the provisions of this Section 5
and in the taking of all such action as may be necessary or appropriate in order
to protect the Conversion  Rights of the holders of the Series C Preferred Stock
against impairment.

          (g)  CERTIFICATE  AS TO  ADJUSTMENTS.  Upon  the  occurrence  of  each
adjustment of the Conversion  Price pursuant to this Section 5, the Corporation,
at its expense,  shall  promptly  compute such  adjustment  or  readjustment  in
accordance  with the  terms  hereof  and  furnish  to each  holder  of  Series C

                                      -13-
<PAGE>

Preferred Stock a certificate  setting forth such adjustment or readjustment and
showing  in  reasonable   detail  the  facts  upon  which  such   adjustment  or
readjustment is based.  The Corporation  shall,  upon the written request at any
time of any holder of Series C Preferred Stock, furnish or cause to be furnished
to such  holder  a like  certificate  setting  forth  (i) such  adjustments  and
readjustments,  (ii) the Conversion  Price at the time in effect,  and (iii) the
number of shares of Common Stock and the amount,  if any, of other property that
at the time would be received upon the conversion of Series C Preferred Stock.

          (h) NOTICES OF RECORD DATE. In the event that this  Corporation  shall
propose at any time:

               (i) to  declare  any  dividend  or  distribution  upon its Common
Stock,  whether in cash, property,  stock or other securities,  whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;

               (ii) to offer for  subscription  pro rata to the  holders  of any
class or  series of its  stock  any  additional  shares of stock of any class or
series or other rights;

               (iii) to effect any  reclassification  or recapitalization of its
Common Stock outstanding involving a change in the Common Stock; or

               (iv) to merge with or into any other corporation,  or sell, lease
or convey all or  substantially  all its property or business,  or to liquidate,
dissolve or wind up;

then, in connection  with each such event,  this  Corporation  shall send to the
holders of the Series C Preferred Stock:

                    (A) at least twenty (20) days' prior  written  notice of the
date on  which a  record  shall be taken  for  such  dividend,  distribution  or
subscription  rights  (and  specifying  the date on which the  holders of Common
Stock shall be entitled thereto) or for determining rights to vote in respect of
the matters referred to in (iii) and (iv) above; and

                    (B) in the case of the matters referred to in (iii) and (iv)
above, at least twenty (20) days' prior written notice of the date when the same
shall take place (and  specifying  the date on which the holders of Common Stock
shall be  entitled  to  exchange  their  Common  Stock for  securities  or other
property deliverable upon the occurrence of such event).

                                      -14-
<PAGE>

          Each such written  notice shall be given by first class mail,  postage
prepaid, addressed to the holders of Series C Preferred Stock at the address for
each such holder as shown on the books of this Corporation.

          (i)  RESERVATION OF STOCK ISSUABLE UPON  CONVERSION.  The  Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock,  solely for the purpose of effecting  the  conversion of
the shares of the Series C Preferred Stock,  such number of its shares of Common
Stock as shall from time to time be sufficient  to effect the  conversion of all
outstanding shares of Series C Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then  outstanding  shares of Series C Preferred  Stock, in
addition  to such other  remedies  as shall be  available  to the holder of such
Series C Preferred  Stock,  the Corporation  will take such corporate  action as
may, in the opinion of its counsel,  be necessary to increase its authorized but
unissued  shares of Common Stock to such number of shares as shall be sufficient
for such purposes,  including,  without limitation,  engaging in best efforts to
obtain the  requisite  stockholder  approval of any  necessary  amendment to the
Corporation's Restated Certificate of Incorporation.

     Section 6. REDEMPTION/CONVERSION.

          (a) RIGHT OF REDEMPTION/CONVERSION. Subject to the rights of series of
authorized  Preferred Stock which may from time to time come into existence,  at
any time on or after the seventh  anniversary of the Original  Issue Date,  each
holder  of  Series  C  Preferred  Stock  shall  have  the  right  to  cause  the
Corporation, at the Corporation's sole option, to either (i) redeem/convert such
Series C Preferred Stock, in whole or in part, in cash, at a redemption price in
an amount  equal to the  Liquidation  Price (as defined in Section  3(a)) at the
time in effect (the "Voluntary Redemption/Conversion Price"), or (ii) so long as
shares of the Common Stock remain listed on NNM or another  national  securities
exchange, to convert such Series C Preferred Stock into fully registered,  fully
paid and  nonassessable  shares of Common  Stock,  with the value of such Common
Stock being  deemed to be equal to 95% of the Market  Price of the Common  Stock
for the thirty (30) trading days immediately  preceding the conversion date (the
"Deemed Conversion Value"). No fractional shares of Common Stock shall be issued
upon such conversion of the Series C Preferred  Stock. In lieu of any fractional
share to which a holder would otherwise be entitled,  the Corporation  shall pay
cash equal to such fraction  multiplied by the Deemed Conversion Value. Any such
conversion shall be conducted in accordance with Section 5(c).

          (b)   OPTIONAL   REDEMPTION/CONVERSION.   From  and  after  the  third
anniversary of the Original Issue Date, the Corporation shall have the right and
option to  redeem/convert  all, but not less than all, shares of the outstanding
Series C  Preferred  Stock.  The  redemption/conversion  price for each share of

                                      -15-
<PAGE>

Series C Preferred  Stock  redeemed  pursuant to this  Section  6(b) shall be an
amount payable in cash equal to the sum of the Liquidation  Price (as defined in
Section  3(a)) at the time in effect  and the  Make-Whole  Payment  (as  defined
hereinafter),  if any  (the  "Redemption/Conversion  Price").  The  "Make  Whole
Payment" per share shall be equal to: (i) from and after the seventh anniversary
of the Original Issue Date,  zero; (ii) from and after the fifth  anniversary of
the  Original  Issue Date but prior to the seventh  anniversary  of the Original
Issue Date, an amount equal to the excess,  if any, of (A) an amount  sufficient
to provide a holder of the Series C Preferred  Stock with a compounded  internal
rate of return of 20% (as measured  from the Original  Issue Date to the date of
payment of the Redemption/Conversion Price on the basis of an initial investment
of  $100.00  per share of Series C  Preferred  Stock)  over (B) the  Liquidation
Price, and (iii) from and after the third anniversary of the Original Issue Date
but prior to the fifth  anniversary  of the Original Issue Date, an amount equal
to the excess,  if any, of (A) an amount  sufficient  to provide a holder of the
Series C Preferred  Stock with a compounded  internal  rate of return of 25% (as
measured  from  the  Original   Issue  Date  to  the  date  of  payment  of  the
Redemption/Conversion Price on the basis of an initial investment of $100.00 per
share of Series C Preferred Stock) over (B) the Liquidation Price.

          (c) The  Corporation  shall  provide each holder of Series C Preferred
Stock with a written notice of redemption/conversion (addressed to the holder at
its address as it appears on the stock transfer books of the  Corporation),  not
earlier  than sixty (60) nor later than  twenty  (20) days before the date fixed
for redemption. The notice of redemption/conversion  shall specify (i) the class
or part of the  class  of  shares  to be  redeemed;  (ii)  the  date  fixed  for
redemption/conversion  (the  "Redemption/Conversion  Date"); (iii) the Voluntary
Redemption/Conversion    Price   or   the   Redemption/Conversion    Price,   as
applicable;(iv)  the place the  holders of Series C  Preferred  Stock may obtain
payment    of    the    Voluntary    Redemption/Conversion    Price    or    the
Redemption/Conversion   Price,   as   applicable,   upon   surrender   of  their
certificates;  and (v) the last date prior to the date of  redemption/conversion
that the right of conversion  of the Series C Preferred  Stock may be exercised.
If funds are available on the date fixed for redemption/conversion, then whether
or not shares are surrendered for payment of the Voluntary Redemption/Conversion
Price or the  Redemption/Conversion  Price,  as applicable,  the shares shall no
longer be outstanding  and the holders thereof shall cease to be stockholders of
the Corporation with respect to the shares  redeemed/converted  on and after the
date  fixed for  redemption/conversion  and shall be  entitled  to  receive  the
Voluntary  Redemption/Conversion  Price or the  Redemption/Conversion  Price, as
applicable,  without  interest upon the surrender of the share  certificate.  If
less  than  all  the  shares  represented  by a  share  certificate  are  to  be
redeemed/converted,  the Corporation shall issue a new share certificate for the
shares not redeemed/converted.

          (d)  If on the  Redemption  Date  funds  of  the  Corporation  legally
available  therefor shall be  insufficient  to redeem all the shares of Series C
Preferred Stock required to be redeemed as provided herein,  funds to the extent

                                      -16-
<PAGE>

legally  available  shall be used for such  purpose  and the  Corporation  shall
effect such  redemption  PRO RATA  according to the number of shares of Series C
Preferred  Stock held by each  holder  subject  to the  redemption  (a  "Partial
Redemption").   The  Corporation  shall  make  additional  Partial   Redemptions
beginning  thirty (30) days after the Redemption  Date and each thirty (30) days
thereafter  until all  tendered or  outstanding,  as the case may be,  shares of
Series C Preferred Stock have been redeemed.

     Section 7. CHANGE-OF-CONTROL REDEMPTION/CONVERSION

          (a) Upon  the  occurrence  of a Change  of  Control  (as such  term is
defined  hereinafter,  each  holder of Series C  Preferred  Stock shall have the
right to require the Corporation,  at the Corporation's  option, to either:  (i)
redeem  such Series C Preferred  Stock,  in cash,  at a price per share equal to
105% of the Liquidated Price at the time in effect,  or (ii) convert such Series
C Preferred Stock into fully registered,  fully paid and nonassessable shares of
Common Stock, at a price of 105% of the Liquidation Price at the time in effect.
In the event the Corporation  elects to convert the shares of Series C Preferred
Stock, the value of the Common Stock per share shall equal the Deemed Conversion
Value (as defined in Section 6(a)).  No fractional  shares of Common Stock shall
be issued  upon  conversion  of the  Series C  Preferred  Stock.  In lieu of any
fractional share to which a holder would otherwise be entitled,  the Corporation
shall pay cash equal to such fraction multiplied by the Deemed Conversion Value.
Any such  conversion  shall be conducted in accordance with Section 5(c). In the
event the Corporation  elects to redeem the shares of Series C Preferred  Stock,
if sufficient funds are not legally  available to redeem all outstanding  shares
of Series C Preferred  Stock tendered for redemption,  then redemption  shall be
carried  out PRO RATA  according  to the number of shares of Series C  Preferred
Stock required to be redeemed as provided herein (a "Partial  Redemption") as of
the Change of Control Redemption Date (as defined hereinafter).  The Corporation
shall make additional Partial  Redemptions  beginning thirty (30) days after the
Change of Control Redemption Date and each thirty (30) days thereafter until all
outstanding shares of Series C Preferred Stock have been redeemed.

     For purposes of this Section 7, "Change of Control" means the occurrence of
any of the following events:

               (i) any  "person"  or "group" (as such terms are used in Sections
13(d)  and  14(d) of the  Securities  Exchange  Act of  1934,  as  amended  (the
"Exchange  Act")) becomes the "beneficial  owner" (as defined in Rules 13d-3 and
13d-5 under the Exchange Act,  except that a person or entity shall be deemed to
have "beneficial ownership" of all securities that such person or entity has the
right to acquire,  whether such right is  exercisable  immediately or only after
the  passage of time),  directly or  indirectly,  of more than a majority of the
voting power of all classes of voting stock of the Corporation;

                                      -17-
<PAGE>

               (ii) the Corporation  consolidates  with, or merges with or into,
another person or entity or conveys,  transfers, leases or otherwise disposes of
all or substantially all of its assets to any person or entity, or any person or
entity  consolidates with, or merges with or into, the Corporation,  in any such
event  pursuant to a transaction  in which the  outstanding  voting stock of the
Corporation  is  converted  into or  exchanged  for  cash,  securities  or other
property, other than any such transaction where (A) the outstanding voting stock
of the  Corporation  is not  converted or exchanged at all (except to the extent
necessary  to  reflect  a change in the  jurisdiction  of  incorporation)  or is
converted into or exchanged for (1) capital stock of the surviving or transferee
person or entity or (2) cash,  securities or other property  (other than capital
stock  described in the  foregoing  clause (1)) of the  surviving or  transferee
person or entity in an amount  that  could be paid as a  Restricted  Payment  as
described under Section 7.4 of the Corporation's Stock Purchase Agreement, dated
as of June 29, 1998, and (B) immediately after such transaction,  no "person" or
"group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act)
is the  "beneficial  owner"  (as  defined  in Rules  13d-3 and  13d-5  under the
Exchange Act, except that a person or entity shall be deemed to have "beneficial
ownership"  of all  securities  that  such  person  or  entity  has the right to
acquire, whether such right is exercisable immediately or only after the passage
of  time),  directly  or  indirectly,  of  more  than a  majority  of the  total
outstanding voting stock of the surviving or transferee person or entity;

               (iii) during any consecutive two-year period,  individuals who at
the  beginning  of  such  period  constituted  the  Board  of  Directors  of the
Corporation  (together  with any new directors  whose  election to such Board of
Directors,  or  whose  nomination  for  election  by  the  stockholders  of  the
Corporation,  was approved by a vote of 66-2/3% of the  directors  then still in
office  who were  either  directors  at the  beginning  of such  period or whose
election or nomination  for election was  previously so approved)  cease for any
reason to  constitute a majority of the Board of  Directors  of the  Corporation
then in office; or

               (iv) the  Corporation is liquidated or dissolved or adopts a plan
of liquidation or dissolution  other than in a Transaction  which  satisfies the
conditions set forth in Section 4(c).

          (b) The  Corporation  shall  provide each holder of Series C Preferred
Stock with a written notice of the occurrence of a Change of Control  (addressed
to the holder at its  address as it appears on the stock  transfer  books of the
Corporation), not earlier than sixty (60) nor later than twenty (20) days before
the  date of such  occurrence.  Such  notice  shall  specify  the  Corporation's
election pursuant to Section 7(a) and a date for redemption payments to be made,

     Section 8. PREEMPTIVE RIGHTS.

          (a)  Unless  the  holders  of a  majority  of the  shares  of Series C
Preferred Stock then outstanding  waive the applicability of this Section 8 to a
particular  issuance of New Securities (as defined below), each holder of shares
of  Series  C  Preferred  Stock  (a  "Preemptive  Right  Holder")  shall  have a
preemptive right to purchase a PRO RATA share of all or any part of any such New
Securities  which the  Corporation  may, from time to time,  propose to sell and
issue if such issuance  reflects a price per share of Common Stock that is lower
than the existing  Conversion  Price (subject to appropriate  adjustment for any
Recapitalization  Events).  A  Preemptive  Right  Holder's  PRO RATA share,  for
purposes of this preemptive  right, is a fraction equal to the aggregate  number
of shares  of  Series C  Preferred  Stock  and/or  Common  Stock  received  upon
conversion of the Series C Preferred Stock then held by such  Preemptive  Rights
Holder divided by the total number of shares of Common Stock of the  Corporation
on a  fully-diluted  basis then  outstanding  (including  after giving pro forma
effect to the  issuance of shares of Common  Stock  issuable  under all options,
warrants and convertible  securities of the Corporation then outstanding and the
issuance of Common Stock or Common Stock  equivalents  pursuant to the Page Call
Transaction).

          (b)  Except  as  set  forth  in the  next  succeeding  sentence,  "New
Securities"  shall mean any shares of Common  Stock,  whether now  authorized or
not, and rights,  options or warrants to purchase  said shares of Common  Stock,
and securities of any type whatsoever that are, or may become,  convertible into
said shares of Common Stock.  Notwithstanding the foregoing, "New Securities" do
not include (i) securities  issued in the acquisition of another  corporation by
the  Corporation  or a  subsidiary  of the  Corporation  by merger,  purchase of
securities,  purchase of substantially all of the assets or other reorganization
or in a transaction  governed by Rule 145 under the Securities  Act, (ii) shares
of Common  Stock issued or issuable,  or options or other  rights  therefor,  to
employees, officers, directors or consultants pursuant to any plan, agreement or
other  arrangement  approved by the Board of  Directors,  (iii) shares of Common
Stock issued or issuable on conversion  of  outstanding  Preferred  Stock or any
convertible securities otherwise permitted to be issued hereunder or pursuant to
the Corporation's Restated Certificate of Incorporation,  (iv) shares of capital
stock issued in connection with the Page Call Transaction or (v) stock issued in
connection with a Recapitalization Event.

          (c) In the event the Corporation  proposes to undertake an issuance of
New Securities  triggering the preemptive  right  hereunder,  it shall give each
Preemptive Right Holder written notice of its intention,  describing the type of
New Securities,  and the price and terms upon which the Corporation  proposes to
issue the same. Each Preemptive Right Holder shall have 15 days from the date of
receipt of any such  notice to agree to  purchase  up to such  Preemptive  Right
Holder's respective PRO RATA share of such New Securities for the price and upon

                                      -19-
<PAGE>

the terms  specified in the notice by giving written  notice to the  Corporation
and stating therein the quantity of New Securities to be purchased.

          (d) If a Preemptive  Right Holder  fails to exercise  such  preemptive
right within said 30-day period,  the Corporation shall have 120 days thereafter
to sell or enter into an agreement (pursuant to which the sale of New Securities
covered thereby shall be closed, if at all, within 60 days from the date of said
agreement) to sell the New  Securities not elected to be purchased by Preemptive
Right  Holders  at the  price  and  upon  the  terms  no more  favorable  to the
purchasers of such securities than specified in the Corporation's notice. In the
event  the  Corporation  has not  sold the New  Securities  or  entered  into an
agreement to sell the New  Securities  within said  120-day  period (or sold and
issued New Securities in accordance  with the foregoing  within 60 days from the
date of said agreement),  the Corporation shall not thereafter issue or sell any
of such New  Securities,  without first  offering such  securities in the manner
provided above.

                                                                 EXHIBIT 4.3

                       AMENDMENT NO. 1 TO RIGHTS AGREEMENT


     This Amendment No. 1 dated June 29, 1998 hereby amends the Rights Agreement
dated as of October  13, 1995 (the  "Agreement"),  between  Arch  Communications
Group, Inc., a Delaware corporation (the "Company"), and The Bank of New York, a
national banking association, as Rights Agent (the "Rights Agent").

                              W I T N E S S E T H:

     WHEREAS, no Person has become an Acquiring Person as such terms are defined
in the Agreement; and

     WHEREAS,  the  Company  has  directed  the Rights  Agent to enter into this
Amendment No. 1 pursuant to Section 27 of the Agreement;

     NOW, THEREFORE,  in consideration of the premises and mutual agreements set
forth herein, the parties hereby agree as follows:

1.   Section  1(a) of the  Agreement  is hereby  deleted in its entirety and the
     following substituted in lieu thereof:

          (a)  "Acquiring  Person" shall mean any Person who or which,
          together with all  Affiliates and Associates of such Person,
          shall be the  Beneficial  Owner of 15% or more of the shares
          of Common Stock then outstanding,  but shall not include (i)
          the Company,  (ii) any Subsidiary of the Company,  (iii) any
          employee benefit plan of the Company or of any Subsidiary of
          the Company, or any Person or entity organized, appointed or
          established  by the  Company for or pursuant to the terms of
          any  such  plan,  (iv)  any  such  Person  who  becomes  the
          beneficial  owner  of 15% or more of the  shares  of  Common
          Stock then  outstanding  as a result of a  reduction  in the
          number  of shares of  Common  Stock  outstanding  due to the
          repurchase  of shares of Common Stock by the Company  unless
          and until such Person, after becoming aware that such Person
          has become the  Beneficial  Owner of 15% or more of the then
          outstanding  shares of  Common  Stock,  acquires  beneficial
          ownership of additional shares of Common Stock  representing
          1% or more of the shares of Common Stock then outstanding or
          (v) an Exempted Person.  Notwithstanding  the foregoing,  if
          the Board of  Directors  of the Company  determines  in good
          faith that a Person  who would  otherwise  be an  "Acquiring
          Person," as defined pursuant to the foregoing  provisions of

<PAGE>

          this paragraph (a), has become such inadvertently,  and such
          Person  divests as  promptly  as  practicable  a  sufficient
          number of shares of Common  Stock so that such Person  would
          no  longer  be the  Beneficial  Owner  of 10% or more of the
          shares of Common  Stock then  outstanding,  then such Person
          shall  not be  deemed to be an  "Acquiring  Person"  for any
          purposes  of this  Agreement  unless and until  such  Person
          shall again become an "Acquiring Person."

2.   Section  1 of the  Agreement  is  hereby  further  amended  by  adding  new
     paragraph (ii) at the end thereof, as follows:

          (ii) "Exempted  Person" shall mean Sandler Capital  Partners
               IV, L.P.  and  Sandler  Capital  Partners IV FTE,  L.P.
               (collectively,  "Sandler"),  unless and until such time
               as Sandler,  together with its Affiliates,  directly or
               indirectly,  becomes the Beneficial  Owner of more than
               24.9% of the  Common  Stock then  outstanding  (or such
               greater  percentage  as  may  result  solely  from  the
               acquisition  of  shares  of  the  Company's   Series  C
               Convertible  Preferred  Stock or shares of Common Stock
               issued to effect the payment of  dividends,  conversion
               or   redemption   thereof),   in  which  event  Sandler
               immediately shall cease to be an Exempted Person.

3.   Section  11(a)(ii)  of the  Agreement is hereby  deleted and the  following
     substituted in lieu thereof:

          (a)(ii)  Subject  to Section  24 of this  Agreement,  in the
          event  that any Person  shall  become an  Acquiring  Person,
          unless the event causing the 15% threshold  (or, in the case
          of an Exempted Person, the 22% threshold) to be crossed is a
          transaction  set  forth in  Section  13(a)  hereof,  or is a
          Permitted  Offer,   then,   promptly   following  the  first
          occurrence of such event, proper provisions shall be made so
          that each holder of a Right (except as provided below and in
          Section  7(e)  hereof)  shall  thereafter  have the right to
          receive,  upon exercise thereof at the then current Purchase
          Price in  accordance  with the terms of this  Agreement,  in
          lieu of a  number  of one  one-  thousandths  of a share  of
          Preferred  Stock,  such number of shares of Common  Stock of
          the  Company   that  equals  the  result   obtained  by  (x)
          multiplying  the  then  current  Purchase  Price by the then
          number of one  one-thousandths of a share of Preferred Stock
          for which a Right was exercisable  immediately  prior to the
          first  occurrence  of a  Section  11(a)(ii)  Event,  and (y)
          dividing   that  product   (which,   following   such  first
          occurrence, shall thereafter be referred to as the "Purchase

<PAGE>

          Price"  for  each  Right  and  for  all   purposes  of  this
          Agreement)  by 50% of the current  market price  (determined
          pursuant to Section  11(d) hereof) per share of Common Stock
          on the date of such occurrence  (such number of shares,  the
          "Adjustment Shares").


     IN WITNESS WHEREOF, the parties have caused this Amendment No. 1 to be duly
executed  and  their  respective  corporate  seals to be  hereunto  affixed  and
attested as of the day and year first written above.

C Loans may be reborrowed.

     2.2. PROCEDURE FOR BORROWING LOANS.

          (a) The Borrower may borrow under the Aggregate  Tranche A Commitments
on any Business Day during the Tranche A Commitment  Period,  provided  that the
Borrower  shall notify the  Administrative  Agent (by telephone or fax) no later
than 1:00 p.m. (A) three Business Days prior to the requested  Credit  Extension
Date in the case of  Eurodollar  Advances  and (B) one Business Day prior to the
requested  Credit  Extension  Date in the  case of ABR  Advances,  in each  case
specifying (1) the aggregate principal amount to be borrowed under the Aggregate
Tranche A Commitments, (2) the requested Credit Extension Date, (3) whether such
borrowing is to consist of one or more Eurodollar Advances,  ABR Advances,  or a
combination  thereof  and  (4) if the  borrowing  is to  consist  of one or more
Eurodollar Advances,  the length of the Interest Period or Periods for each such
Eurodollar  Advance  (subject to the  provisions  of the  definition of Interest
Period).  Each such notice shall be  irrevocable  and confirmed  immediately  by
delivery to the Administrative Agent of a Credit Request. Each ABR Advance shall
be in an  aggregate  principal  amount  equal to  $100,000 or such amount plus a
whole multiple of $100,000 in excess thereof,  or, if less, the unused amount of
the Aggregate Tranche A Commitments,  and each Eurodollar Advance shall be in an
aggregate  principal  amount  equal  to  $500,000  or such  amount  plus a whole
multiple of $100,000 in excess thereof.  If, with respect to any borrowing,  the
Borrower shall fail to give due notice as provided in this Section, the Borrower
shall be deemed to have selected an ABR Advance for such borrowing.

          (b) Upon receipt of such notice of borrowing  from the  Borrower,  the
Administrative  Agent shall promptly notify each Lender which is a member of the
Class from which a Loan has been requested of such notice of borrowing.  Subject
to its receipt of the notice referred to in the preceding sentence, each Tranche
A Lender will make the amount of its Tranche A Percentage of each such borrowing
of Tranche A Loans available to the Administrative  Agent for the account of the
Borrower at the Payment Office not later than 2:30 p.m., on the relevant  Credit
Extension Date requested by the Borrower,  in funds immediately available to the
Administrative  Agent at such  office.  The  amounts  so made  available  to the
Administrative  Agent on such Credit  Extension  Date will then,  subject to the
satisfaction  of the terms and conditions of this Agreement as determined by the
Administrative  Agent,  be made  available  on such date to the  Borrower by the
Administrative  Agent at the  Payment  Office by  crediting  the  account of the
Borrower on the books of such office with the aggregate of said amounts received
by the Administrative Agent. Unless the Administrative Agent shall have received
prior  notice  from a Lender  (by  telephone  or  otherwise,  such  notice to be
confirmed by telecopy or other  writing) that it will not make  available to the
Administrative  Agent its Tranche A  Percentage  of any Loans  requested  by the
Borrower and with respect to which it has a Commitment, the Administrative Agent
may assume that such Lender has made such share available to the  Administrative
Agent on the requested Credit Extension Date in accordance with this

                                      -32-
<PAGE>


Section,  provided that such Lender  received  notice of the proposed  borrowing
from the  Administrative  Agent, and the  Administrative  Agent may, in reliance
upon such  assumption,  make available to the Borrower on such Credit  Extension
Date a corresponding  amount. If and to the extent such Lender shall not have so
made such share  available  to the  Administrative  Agent,  such  Lender and the
Borrower severally agree to pay to the Administrative  Agent forthwith on demand
such  corresponding  amount (to the extent not  previously  paid by the  other),
together  with  interest  thereon for each day from the date such amount is made
available  to  the  Borrower   until  the  date  such  amount  is  paid  to  the
Administrative Agent, at a rate per annum equal to, in the case of the Borrower,
the applicable  interest rate set forth in Section 3.1, and, in the case of such
Lender,  the  Federal  Funds Rate in effect on such date (as  determined  by the
Administrative  Agent). Such payment by the Borrower,  however, shall be without
prejudice to its rights  against  such  Lender.  If such Lender shall pay to the
Administrative Agent such corresponding  amount, such amount so paid (excluding,
however,  any interest  payable on such amount) shall  constitute  such Lender's
Loan as part of such Loans for purposes of this  Agreement,  which Loan shall be
deemed to have been made by such Lender on the Credit  Extension Date applicable
to such Loans.

          (c) If a Lender makes a new Loan to the Borrower on a Credit Extension
Date on which the Borrower is to repay a Loan of such Lender of the same type or
make a scheduled amortization payment on a Loan of such Lender of the same type,
such Lender shall apply the proceeds of such new Loan to make such  repayment or
scheduled  amortization payment, and only the excess of the proceeds of such new
Loan over the Loan being repaid or  scheduled  amortization  payment  being made
need be made available to the Administrative Agent.

          (d) Notices of borrowing given by telephone shall be deemed given when
made by telephone and the Administrative  Agent and the Lenders may rely thereon
whether or not such notice is confirmed by the delivery of a Credit Request.

     2.3. TERMINATION OR REDUCTION OF THE AGGREGATE TRANCHE A COMMITMENTS.

          (a) VOLUNTARY  REDUCTIONS.  The Borrower shall have the right, upon at
least  three  Business  Days'  prior  written  notice  from the  Borrower to the
Administrative  Agent,  at  any  time  to  terminate  the  Aggregate  Tranche  A
Commitments or from time to time to reduce  permanently the unused amount of the
Aggregate Tranche A Commitments to an amount not less than the Aggregate Tranche
A Exposure (after giving effect to any contemporaneous  payment or prepayment of
Tranche A Loans or  Reimbursement  Obligations).  Any such reduction shall be in
the amount of $1,000,000 or such amount plus a whole multiple of $100,000.

          (b) MANDATORY SCHEDULED REDUCTIONS.  On the dates set forth below, the
Aggregate  Tranche A Commitments  shall be permanently  reduced on the following

of a reduction  or  prepayment  required by Section  2.4 hereof,  the  Aggregate
Tranche B  Commitments  shall have been  terminated  or no longer  exist and the
Tranche  B Loans  shall  have  been  paid  in  full,  the  Aggregate  Tranche  A
Commitments shall be permanently reduced in an amount equal to (i) the Aggregate
Prepayment/Reduction  Amount to be applied as of such date  pursuant  to Section

Tranche B Commitments  and Tranche B Loans pursuant to the provisions of Section
2.4 of the Tranche B Credit  Agreement)  MINUS (ii) the product of the Aggregate
Tranche C Percentage and the Aggregate Prepayment/Reduction Amount to be applied
as of such date.

          (e)  REDUCTIONS OF LETTER OF CREDIT  COMMITMENT.  The Letter of Credit
Commitment  shall not be  reduced  until  such time as the  Aggregate  Tranche A
Commitments shall equal such Letter of Credit  Commitment,  and thereafter shall
in each case be  reduced,  automatically,  by a sum equal to the  amount of each
such reduction in the Aggregate Tranche A Commitments.

               (f) IN  GENERAL.  Each  reduction  of  the  Aggregate  Tranche  A
Commitments  shall be made by reducing each Lender's  Tranche A Commitment by an
amount equal to such Lender's  Tranche A Percentage of such reduction,  and each
reduction of the Aggregate Tranche A Commitments made pursuant to Section 2.3(a)
or 2.3(d)  shall be applied to the  remaining  Aggregate  Tranche A  Commitments
reductions set forth in Section 2.3(b) on a pro rata basis.  Simultaneously with
each reduction of the Aggregate  Tranche A  Commitments,  the Borrower shall pay
the  Tranche A  Commitment  Fee  accrued  on the  amount by which the  Aggregate
Tranche A Commitments has been reduced.

                                                   accrued  and unpaid  interest
                                                   thereon.

          (b) VOLUNTARY PREPAYMENTS. The Borrower may, at its option, prepay the
Loans,  in whole or in part, at any time and from time to time, by notifying the
Administrative  Agent in writing at least one Business Day prior to the proposed
prepayment  date in the case of ABR Advances,  and at least three  Business Days
prior to the proposed  prepayment  date in the case of Eurodollar  Advances,  in
each case  specifying (i) whether the Loans to be prepaid consist of (A) Tranche
A Loans,  Tranche C Loans or a combination  thereof,  and (B) an ABR Advance,  a

(iii) the date of prepayment.  Such notice shall be irrevocable  and the payment

together  with  accrued  interest  to the  date of such  payment  on the  amount

Advances  which were made (whether as the result of a borrowing or a conversion)
on the same  date  and  which  had the same  Interest  Period,  the  outstanding
principal  amount of such  Eurodollar  Advances made (whether as the result of a
borrowing  or a  conversion)  shall not be less than  (subject  to Section  3.3)
$500,000.

Borrower  shall  prepay or repay the  Tranche A Loans or  terminate  Letters  of
Credit by the amount,  if any, by which the Aggregate Tranche A Exposure exceeds
the amount of the Aggregate  Tranche A Commitments  as so reduced or terminated,
provided, however, if the termination of the Aggregate Tranche A Commitments was
caused solely by the occurrence of the Adjusted  Indenture  Maturity Date,  such
prepayment of Tranche A Loans and  termination  of Letters of Credit as required
by this  Section  shall be made 30 days  after the  occurrence  of the  Adjusted
Indenture Maturity Date.

          (d) OTHER MANDATORY PREPAYMENTS.  The Tranche C Loans shall be prepaid
at the times and in the amounts required by Section 2.4.

          (e) APPLICATION OF PREPAYMENTS. Each prepayment of the Tranche C Loans
pursuant to Sections  2.4(a),  (b) and (c) and Section  2.5(b)  shall be applied

          (f) IN GENERAL.  Unless  otherwise  specified  by the  Borrower,  each
prepayment  of  the  Loans  shall  first  be  applied  to ABR  Advances.  If any
prepayment is made in respect of any  Eurodollar  Advance,  in whole or in part,
prior to the last day of the applicable  Interest Period, the Borrower agrees to
indemnify the Lenders in accordance with Section 3.4.

     2.6. LETTERS OF CREDIT.

          (a) AVAILABILITY;  PROCEDURE.  (i) The Borrower may request the Letter
of Credit  Issuer to issue  standby  letters of credit (the "LETTERS OF CREDIT";
each, individually,

                                      -36-
<PAGE>


a "LETTER OF CREDIT") during the period from the Second  Restatement Date to the
tenth  Business  Day  prior  to the  Tranche  A  Maturity  Date,  provided  that
immediately  after the  issuance  of each  Letter of Credit the Letter of Credit
Exposure  of all  Tranche  A  Lenders  would  not  exceed  the  Letter of Credit
Commitment  and the Aggregate  Tranche A Exposure would not exceed the Aggregate
Tranche A  Commitments.  To request  the  issuance  of a Letter of  Credit,  the
Borrower shall notify the  Administrative  Agent and the Letter of Credit Issuer
by the delivery of a Credit Request,  which shall be sent by facsimile and shall
be irrevocable  (confirmed promptly, and in any event within five Business Days,
by the delivery to the Administrative  Agent of a Credit Request manually signed
by the  Borrower),  at least three  Business Days prior to the requested date of
issuance,  specifying  (A) the  beneficiary  of such  Letter of Credit,  (B) the
Borrower's proposal as to the conditions under which a drawing may be made under
such Letter of Credit and the  documentation  to be required in respect thereof,
(C) the maximum amount to be available under such Letter of Credit,  and (D) the
requested  dates of  issuance  and  expiration.  Such  Credit  Request  shall be
accompanied  by a duly completed  application  for such Letter of Credit on such
forms as may be made  available from time to time by the Letter of Credit Issuer
and such other certificates, documents (including a reimbursement agreement) and
other  information  as may be  required  by  the  Letter  of  Credit  Issuer  in
accordance with its customary  procedures  (collectively,  the "LETTER OF CREDIT
DOCUMENTATION").  Upon  receipt of such Credit  Request from the  Borrower,  the
Administrative  Agent shall promptly notify each Lender thereof.  Subject to the
satisfaction of the terms and conditions of this Agreement, the Letter of Credit
Issuer shall issue each requested Letter of Credit. In the event of any conflict
between the provisions of this Agreement and any Letter of Credit Documentation,
the provisions of this Agreement shall control.

          (b) TERMS OF  LETTERS OF CREDIT.  Each  Letter of Credit  shall (i) be
issued for the account of the Borrower and in support of obligations, contingent
or otherwise,  of the Borrower or any Subsidiary  arising in the ordinary course
of business,  and (ii) have an expiration  date that shall be not later than the
earlier  of (A)  twelve  months  after the date of  issuance  thereof or (B) ten
Business Days before the Tranche A Maturity  Date,  provided that the expiration
date of such  Letter of Credit may be  extended  or such Letter of Credit may be
renewed,  provided,  further,  that any renewal,  or any extension of any expiry
date,  of a Letter of Credit  shall  constitute  the  issuance of such Letter of
Credit for all purposes of this Agreement.

          (c) LETTER OF CREDIT PARTICIPATIONS.  Immediately upon the issuance of
a Letter of Credit, the Letter of Credit Issuer shall be deemed to have sold and
transferred to each Tranche A Lender,  and each Tranche A Lender shall be deemed
to have irrevocably and  unconditionally  purchased and received from the Letter
of Credit  Issuer,  without  recourse or  warranty,  an  undivided  interest and
participation,  to the extent of such Lender's Tranche A Percentage  thereof, in
such Letter of Credit and the  obligations of the Borrower with respect  thereto
and any  security  therefor  and any  guaranty  pertaining  thereto  at any time
existing.

          (d) DRAWINGS ON LETTERS OF CREDIT.  The Letter of Credit  Issuer shall
promptly  notify  (i) each  Tranche  A Lender of the  Letter of Credit  Issuer's
receipt of a drawing  request under any Letter of Credit,  stating the amount of
such Lender's Tranche A Percentage of such drawing request and the date on which
such request will be honored and (ii) the Borrower of the amount of such drawing
request and the date on which such request  will be honored.  Any failure of the
Letter of Credit  Issuer to give or any delay in the  Letter of Credit  Issuer's
giving any such  notice  shall not release or diminish  the  obligations  of the
Borrower or any Tranche A Lender hereunder. In determining whether to

                                      -37-
<PAGE>


pay under any  Letter of  Credit,  the  Letter of Credit  Issuer  shall  have no
obligation  to any Tranche A Lender or the  Borrower  other than to confirm that
any  documents  required to be  delivered  under such Letter of Credit have been
delivered and that they appear to comply on their face with the  requirements of
such Letter of Credit. In the absence of gross negligence or willful  misconduct
on the part of the Letter of Credit  Issuer,  the Letter of Credit  Issuer shall
have no  liability  to any Tranche A Lender or the Borrower for any action taken
or omitted to be taken by it under or in  connection  with any Letter of Credit,
including any such action  negligently taken or negligently  omitted to be taken
by it.

          (e) REIMBURSEMENT.  The Borrower shall pay to the Administrative Agent
for  the  account  of the  Letter  of  Credit  Issuer  on  demand  therefor,  in
immediately  available funds, the amount of all Reimbursement  Obligations owing
to the  Letter of Credit  Issuer  under any  Letter  of  Credit,  together  with
interest thereon as provided in Section 3.1,  irrespective of any claim, setoff,
defense or other right that the Borrower may have at any time against the Letter
of Credit  Issuer or any other  Person.  In the event  that the Letter of Credit
Issuer makes any payment  under any Letter of Credit and the Borrower  shall not
have repaid such amount to the Letter of Credit  Issuer when due,  the Letter of
Credit Issuer shall promptly  notify each Tranche A Lender of such failure,  and
each such Lender shall promptly and  unconditionally  pay to the  Administrative
Agent,  for the  account  of the  Letter of Credit  Issuer,  the  amount of such
Lender's Tranche A Percentage of such payment in immediately  available funds on
the  Business  Day the Letter of Credit  Issuer so notifies  such Lender if such
notice is given  prior to 12:00  Noon or, if such  notice is given  after  12:00
Noon, such Lender shall make its Tranche A Percentage of such payment  available
to the  Letter  of  Credit  Issuer  prior to 12:00  Noon on the next  succeeding
Business Day.

          (f)  LENDERS'  OBLIGATIONS.  If and to the extent any Tranche A Lender
shall  not  make  such  Lender's  Tranche  A  Percentage  of  any  Reimbursement
Obligations available to the Letter of Credit Issuer when due in accordance with
Section 2.6(e), such Lender agrees to pay, on demand,  interest to the Letter of
Credit  Issuer on such unpaid  amount for each day from the date such payment is
due until the date such amount is paid in full to the Letter of Credit Issuer at
a rate per annum  equal to the  greater  of the  Federal  Funds  Rate and a rate
determined by the Letter of Credit Issuer in  accordance  with banking  industry
rates on  interbank  compensation.  The  obligations  of the Lenders  under this
Section  2.6(f) are several and not joint or joint and several,  and the failure
of any Lender to make  available  to the Letter of Credit  Issuer its  Tranche A
Percentage of any Reimbursement  Obligations when due in accordance with Section
2.6(e)  shall not relieve any other Lender of its  obligation  hereunder to make
its Tranche A Percentage of such Reimbursement  Obligations so available when so
due, but no Lender shall be  responsible  for the failure of any other Lender to
make such other Lender's Tranche A Percentage of such Reimbursement  Obligations
so available when so due.

          (g)  RESCISSION.  Whenever  the  Letter of Credit  Issuer  receives  a
payment of a  Reimbursement  Obligation  from or on behalf of the Borrower as to
which the Letter of Credit  Issuer has  received  any  payment  from a Tranche A
Lender  pursuant to Section  2.6(e),  the Letter of Credit Issuer shall promptly
pay to such Lender an amount equal to such Lender's Tranche A Percentage of such
payment from or on behalf of the Borrower. If any payment by or on behalf of the
Borrower and received by the Letter of Credit  Issuer with respect to any Letter
of Credit is  rescinded  or must  otherwise  be returned by the Letter of Credit
Issuer for any reason and the Letter of Credit Issuer has paid to any Lender any
portion thereof, each such Lender shall forthwith pay over to the

                                      -38-
<PAGE>


Letter of Credit Issuer an amount equal to such Lender's Tranche A Percentage of
the amount that must be so returned by the Letter of Credit Issuer.

          (h) EXPENSES.  Each Tranche A Lender, upon the demand of the Letter of
Credit Issuer,  shall  reimburse the Letter of Credit Issuer,  to the extent the
Letter of Credit  Issuer has not been  reimbursed  by the Borrower  after demand
therefor, for the reasonable costs and expenses (including reasonable attorneys'
fees) incurred by the Letter of Credit Issuer in connection  with the collection
of  amounts  due  under,  and the  preservation  and  enforcement  of any rights
conferred  by, any Letter of Credit or the  performance  of the Letter of Credit
Issuer's  obligations as issuer of the Letters of Credit under this Agreement in
respect  thereof,  to the extent of such  Lender's  Tranche A Percentage  of the
amount of such costs and expenses,  provided,  however,  that no Lender shall be
liable for the payment of any portion of such liabilities,  obligations, losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
to the extent the same result from the gross negligence or willful misconduct of
the Letter of Credit Issuer.  The Letter of Credit Issuer shall refund any costs
and expenses reimbursed by such Lender that are subsequently  recovered from the
Borrower in an amount equal to such Lender's Tranche A Percentage thereof.

          (i) OBLIGATIONS ABSOLUTE.  The obligation of the Borrower to reimburse
the Letter of Credit Issuer  pursuant to this Section 2.6, and the obligation of
each  Tranche A Lender to make  available  to the  Letter of Credit  Issuer  the
amounts  set forth in this  Section  2.6 shall be  absolute,  unconditional  and
irrevocable under any and all circumstances, shall be made without reduction for
any set-off,  counterclaim or other deduction of any nature whatsoever,  may not
be  terminated,  suspended  or delayed for any reason  whatsoever,  shall not be
subject to any  qualification  or exception and shall be made in accordance with
the terms and conditions of this Agreement  under all  circumstances,  including
any of the following  circumstances:  (1) any lack of validity or enforceability
of this Agreement or any of the other Loan  Documents,  (2) the existence of any
claim,  setoff,  defense or other right that the  Borrower  may have at any time
against a beneficiary named in a Letter of Credit,  any transferee of any Letter
of Credit (or any Person for whom any such transferee may be acting), the Letter
of Credit  Issuer,  any Lender or any other Person,  whether in connection  with
this Agreement,  any other Loan Document, any Letter of Credit, the transactions
contemplated in the Loan Documents or any unrelated transactions  (including any
underlying  transaction  between the Borrower and the  beneficiary  named in any
such  Letter of  Credit),  (3) any  draft,  certificate  or any  other  document
presented under any Letter of Credit proving to be forged,  fraudulent,  invalid
or  insufficient  in any  respect  or any  statement  therein  being  untrue  or
inaccurate in any respect, (4) the surrender or impairment of any Collateral for
the  performance or observance of any of the terms of any of the Loan Documents,
or (5) the occurrence of any Default or Event of Default.  Nothing  contained in
this  Section  2.6(i),  however,  shall  require  the  Borrower or any Lender to
reimburse  the Letter of Credit Issuer for any amounts that become due by reason
of the Letter of Credit Issuer's gross negligence or wilful misconduct.

     2.7. USE OF PROCEEDS.

          The  proceeds  of the  Extensions  of  Credit  shall  be used  solely,
directly or indirectly,  (i) for general corporate  purposes of the Borrower and
its  Subsidiaries,  including  Capital  Expenditures  and working  capital,  not
inconsistent  with the provisions  hereof,  (ii) to finance  Acquisitions to the
extent permitted by Section 8.6, (iii) to make Restricted

Payments to the extent  permitted by Section 8.5, and (iv) to pay the reasonable
out-of-pocket  fees and expenses incurred by the Borrower in connection with the
transactions contemplated by the Transaction Documents. Notwithstanding anything
to the contrary contained in any Loan Document, the Borrower agrees that no part
of  the  proceeds  of any  Extensions  of  Credit  will  be  used,  directly  or
indirectly,  for a purpose which  violates any law,  including the provisions of
Regulations T, U or X.

     2.8. NOTES; REGISTRATION.

          (a) IN GENERAL.  The Loans made by each Lender shall be evidenced by a
Note.

          (b) REGISTERED NOTES.

               (i) Any Foreign  Credit  Party  which is not a "bank"  within the
     meaning  of  Section  881(c)(3)(A)  of the  Code  and  which  could  become
     completely  exempt from  withholding of U.S. Taxes in respect of payment of
     any  obligations  due it under the Loan  Documents  relating  to any of its
     Loans,  if such Loans were in registered  form for U.S.  Federal income tax
     purposes,  may request the Borrower (through the Administrative Agent), and
     the Borrower  agrees  thereupon,  (A) in the case of a Foreign Credit Party
     listed on the  signature  pages  hereof,  to exchange  such Foreign  Credit
     Party's Note for a promissory  note  registered as provided in clause (iii)
     below (each, a "REGISTERED NOTE") and (B) in the case of each other Foreign
     Credit Party, to issue to such Foreign Credit Party its Note in the form of
     a Registered  Note. A Registered  Note may not be exchanged for a Note that
     is not in registered form.

               (ii) Each  Foreign  Credit  Party  holding a  Registered  Note (a
     "REGISTERED  NOTEHOLDER")  and,  if such  Foreign  Credit  Party is not the
     beneficial  owner  thereof,  such  beneficial  owner,  shall deliver to the
     Borrower and the Administrative  Agent prior to or at the time such Foreign
     Credit Party becomes a Registered  Noteholder,  a Form W-8  (Certificate of
     Foreign  Status of the  Department of Treasury of the United States) or the
     successor  form thereto and any related forms  (including,  if  applicable,
     Form  W-8C) and  related  forms as may from time to time be  adopted by the
     relevant  taxing  authorities  of the United  States  which are required to
     allow  payments of portfolio  interest  (within the meaning of Code Section
     871(b) to be made free of United States  withholding  tax. Each  Registered
     Noteholder shall also deliver to the Borrower and the Administrative  Agent
     an annual certificate stating that such Registered Noteholder or beneficial
     owner,  as the case may be, is not a "bank"  within the  meaning of section
     881(c)(3)(A)  of the  Code  and  is  not  otherwise  described  in  Section
     881(c)(3) of the Code. Each Registered  Noteholder or beneficial  owner, as
     the case may be, shall promptly notify the Borrower and the  Administrative
     Agent if at any time such Registered Noteholder or beneficial owner, as the
     case may be,  determines that it is no longer in a position to provide such
     certificate  (or any other form of  certification  adopted by the  relevant
     taxing authorities of the United States for such purposes).

               (iii) The Borrower shall maintain,  or cause to be maintained,  a
     register (the "REGISTER") which shall be kept by the  Administrative  Agent
     on behalf of the Borrower at no extra charge to the Borrower at the Payment
     Office  which shall set forth (A) the names and  addresses  of each Lender,
     including each registered  owner of Loans  evidenced by a Registered  Note,
     (B) the Class or Classes of

                                      -40-
<PAGE>


     the Loans of such  Lender,  (C) if such  Lender is a Tranche A Lender,  the
     amount of its Tranche A Commitment and the principal  amount of its Tranche
     A Loans outstanding from time to time and (D) if such Lender is a Tranche C
     Lender, the principal amount of its Tranche C Loan outstanding from time to
     time.  The entries in the Register  shall be binding and conclusive for all
     purposes,  absent manifest error,  and the Borrower,  and each Credit Party
     shall treat each Person  whose name is recorded in the Register as a Lender
     for all purposes under this Agreement.

               (iv)  In  addition  to  the   requirements  of  Section  11.5,  a
     Registered  Note (and the  Loans  evidenced  thereby)  may be  assigned  or
     otherwise  transferred  in whole or in part  only by  registration  of such
     assignment  or transfer of such  Registered  Note (and the Loans  evidenced
     thereby) on the  REGISTER  (and each  Registered  Note shall  expressly  so
     provide).  Any  assignment or transfer of all or part of such Loans and the
     Registered  Note  evidencing  the same shall be  registered on the Register
     only upon  compliance  with the  requirements of Section 11.5 and surrender
     for   registration  of  assignment  or  transfer  of  the  Registered  Note
     evidencing  such  Loans,  duly  endorsed  by (or  accompanied  by a written
     instrument  of  assignment or transfer  fully  executed by) the  Registered
     Noteholder  thereof,  and thereupon one or more new Registered Notes in the
     same  aggregate   principal  amount  shall  be  issued  to  the  designated
     assignee(s)  or   transferee(s).   Prior  to  the  due   presentation   for
     registration  of transfer of any  Registered  Note,  the  Borrower  and the
     Administrative  Agent  shall  treat the Person in whose name such Loans and
     the Registered  Note evidencing the same is registered as the owner thereof
     for the  purpose  of  receiving  all  payments  thereon  and for all  other
     purposes, notwithstanding any notice to the contrary.

     2.9. PAYMENTS; PRO RATA TREATMENT AND SHARING OF SET-OFFS.

          (a) PAYMENTS  GENERALLY.  (i) Except as provided below,  all payments,
including prepayments,  of principal and interest on the Loans, of the Tranche A
Commitment Fee, the Letter of Credit Fees and of all other amounts to be paid by
the Borrower under the Loan Documents (the Tranche A Commitment  Fee, the Letter
of  Credit  Fees,  together  with  all  of  such  other  fees,  being  sometimes
hereinafter  collectively  referred  to as the  "FEES")  shall  be  made  to the
Administrative  Agent,  prior to 1:00 p.m. on the date such  payment is due, for
the account of the applicable  Credit Parties at the Payment Office,  in Dollars
and in immediately  available  funds,  without  set-off,  offset,  recoupment or
counterclaim.  The failure of the Borrower to make any such payment by such time
shall not  constitute a Default,  provided that such payment is made on such due
date, but any such payment made after 1:00 p.m. on such due date shall be deemed
to have  been  made on the next  Business  Day for the  purpose  of  calculating
interest on amounts  outstanding on the Loans.  As between the Borrower and each
Credit Party,  any payment by the Borrower to the  Administrative  Agent for the
account of such Credit  Party  shall be deemed to be payment by the  Borrower to
such Credit  Party.  Notwithstanding  the  foregoing,  all payments  pursuant to
Sections  3.4,  3.5,  3.6 and 11.4 shall be paid  directly  to the Credit  Party
entitled  thereto.  If any  payment  under the Loan  Documents  shall be due and
payable on a day which is not a Business  Day, the due date  thereof  (except as
otherwise  provided with respect to Interest  Periods)  shall be extended to the
next  Business  Day and (except with respect to payments in respect of the Fees)
interest  shall be payable at the applicable  rate specified  herein during such
extension,  provided, however, that if such next Business Day would be after the
(i) with  respect  to  Tranche A Loans and  Letters  of  Credit,  the  Tranche A
Maturity Date and (ii) the Tranche C Loans,  the Tranche C Maturity  Date,  such
payment shall instead be due on the immediately preceding Business Day.


                                      -41-
<PAGE>


               (ii)  If at any  time  insufficient  funds  are  received  by and
available  to the  Administrative  Agent to pay fully all amounts of  principal,
interest  and Fees then due  hereunder,  such funds  shall be applied (A) first,
towards payment of interest and Fees then due under the Loan Documents,  ratably
among the parties  entitled  thereto in accordance  with the amounts of interest
and Fees then due to such parties, and (B) second,  towards payment of principal
then due under the Loan Documents, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties.

          (b)  SET-OFF.  In  addition  to any rights and  remedies of the Credit
Parties  provided by law, upon and after the acceleration of all the obligations
of the Borrower under the Loan Documents to which it is a party,  or at any time
upon the  occurrence  and during the  continuance  of an Event of Default  under
Sections  9.1(a) or (b),  each Credit Party shall have the right,  without prior
notice to any Loan Party,  any such notice being  expressly  waived by each Loan
Party to the extent not  prohibited  by  applicable  law,  to set-off  and apply
against any  indebtedness,  whether matured or unmatured,  of such Loan Party to
such Credit  Party any amount  owing from such Credit  Party to such Loan Party,
at, or at any time after, the happening of any of the above-mentioned events. To
the extent not prohibited by applicable  law, the aforesaid right of set-off may
be exercised by any Credit Party  against such Loan Party or against any trustee
in  bankruptcy,  custodian,  debtor in  possession,  assignee for the benefit of
creditors,  receiver, or execution, judgment or attachment creditor of such Loan
Party,  or against anyone else claiming  through or against such Loan Party,  or
such trustee in bankruptcy,  custodian,  debtor in possession,  assignee for the
benefit of creditors,  receiver, or execution,  judgment or attachment creditor,
notwithstanding  the  fact  that  such  right of  set-off  shall  not have  been
exercised  by such  Credit  Party prior to the making,  filing or  issuance,  or
service  upon  such  Credit  Party  of,  or of  notice  of,  any such  petition,
assignment  for the benefit of creditors,  appointment  or  application  for the
appointment of a receiver, or issuance of execution, subpoena, order or warrant.
Each Credit Party agrees promptly to notify the Borrower and the  Administrative
Agent after any such set-off and application made by such Credit Party, provided
that the  failure to give such  notice  shall not affect  the  validity  of such
set-off and application.

          (c)  ADJUSTMENTS.  If any Lender  shall  obtain any  payment  (whether
voluntary,  involuntary,  through  the  exercise  of any  right of  set-off,  or
otherwise) in respect of the principal of or interest on its Loans, resulting in
such Lender receiving payment of a greater proportion of the aggregate principal
amount of, or accrued  interest on, such Loans than the  proportion  received by
any other  Lender,  then the Lender  receiving  such  greater  proportion  shall
promptly  purchase,  at face value for cash,  participations in the Loans to the
extent  necessary  so that the  benefit of such  payment  shall be shared by the
Lenders  ratably in  accordance  with the  aggregate  amount of principal of and
accrued interest on their respective Loans,  provided,  however, that (i) if all
or any portion of such payment is  thereafter  recovered or repaid in good faith
settlement of a pending or threatened avoidance claim, such participations shall
be rescinded and the purchase price returned, in each case to the extent of such
recovery or settlement  payment,  and (ii) the provisions of this Section 2.9(c)
shall not be construed to apply to any payment made by the Borrower  pursuant to
and in  accordance  with the  express  terms of this  Agreement  or any  payment
obtained  by a  Lender  as  consideration  for  the  assignment  of or sale of a
participation in any of its Loans to any assignee or participant,  other than to
the Borrower or any Subsidiary or Affiliate  thereof (as to which the provisions
of this Section  2.9(c) shall apply).  The Borrower  agrees that any Lender that
purchased a  participation  pursuant to this subsection may exercise such rights
to payment (including the right of set-off) with

                                      -42-
<PAGE>


respect to such  participation  as fully as such Lender were the direct creditor
of the Borrower in the amount of such participation.


3.   INTEREST, FEES, YIELD PROTECTIONS, ETC.

     3.1. INTEREST RATE AND PAYMENT DATES.

          (a) PRIOR TO MATURITY.  Prior to maturity,  the outstanding  principal
balance of the Loans shall bear interest on the unpaid  principal amount thereof
at the applicable interest rate or rates per annum set forth below:

               Advances                                   Rate
               --------                                   ----
        Each ABR Advance                Alternate Base Rate plus the Applicable 
                                        Margin applicable to ABR Advances.

        Each                            Eurodollar Advance Eurodollar Rate for 
                                        the applicable Interest Period plus the
                                        Applicable Margin applicable to 
                                        Eurodollar Advances.

          (b) EXTENT OF DEFAULT;  LATE CHARGES.  Notwithstanding  the foregoing,
after the  occurrence  and during the  continuance  of an Event of Default,  the
outstanding  principal  balance of all Loans  shall bear  interest  at a rate of
interest  per  annum  equal  to 2% above  the  rate  which  would  otherwise  be
applicable   pursuant  to  Section  3.1(a).   If  any  interest,   Reimbursement
Obligation,  Commitment  Fee,  Letter of Credit Fee or other amount  (other than
principal of the Loans)  payable  under the Loan  Documents is not paid when due
(whether at the stated maturity  thereof,  by  acceleration or otherwise),  such
overdue amount shall,  to the extent  permitted by applicable law, bear interest
at a rate per annum equal to the Alternate Base Rate plus the Applicable  Margin
plus  2%,  in each  case  from the date of such  nonpayment  until  paid in full
(before  as well as after  judgment).  All such  interest  shall be  payable  on
demand.

          (c) IN GENERAL.  Interest on (i) ABR  Advances to the extent  based on
the BNY Rate shall be  calculated  on the basis of a 365 or 366-day year (as the
case may be) and (ii) ABR Advances to the extent based on the Federal Funds Rate
and  Eurodollar  Advances shall be calculated on the basis of a 360-day year, in
each case for the actual  number of days  elapsed,  including  the first day but
excluding the last. Except as otherwise provided in Section 3.1(b),  interest on
each Loan shall be payable in arrears on each Interest  Payment Date  applicable
thereto and upon payment (including  prepayment) in full thereof.  Any change in
the interest rate on a Loan  resulting  from a change in the Alternate Base Rate
shall  become  effective  as of the opening of business on the day on which such
change in the Alternate  Base Rate shall become  effective.  The  Administrative
Agent shall,  as soon as  practicable  following  request  therefor,  notify the
Borrower  and the  Lenders  of the  effective  date and the  amount of each such
change in the Alternate Base Rate, but any failure to so notify shall not in any
manner affect the obligation of the Borrower to pay interest on the Loans in the
amounts and on the dates required. Each determination of the Alternate Base Rate
or a Eurodollar  Rate by the  Administrative  Agent  pursuant to this  Agreement
shall be conclusive and binding on the Borrower and the Lenders absent  manifest
error.  At no time shall the interest  rate payable on the Loans,  together with
the Commitment Fees,  Letter of Credit Fees and all other fees and other amounts
payable  under the Loan  Documents,  to the  extent  the same are  construed  to
constitute interest, exceed the

                                      -43-
<PAGE>


Highest  Lawful Rate.  If interest  payable to a Lender on any date would exceed
the maximum amount  permitted by the Highest Lawful Rate, such interest  payment
shall  automatically be reduced to such maximum permitted  amount,  and interest
for any subsequent  period, to the extent less than the maximum amount permitted
for such period by the Highest  Lawful  Rate,  shall be  increased by the unpaid
amount of such  reduction.  Any  interest  actually  received  for any period in
excess of such maximum  allowable amount for such period shall be deemed to have
been applied as a prepayment of the Loans. The Borrower acknowledges that to the
extent  interest  payable on the ABR Advances is based on the BNY Rate,  the BNY
Rate is only one of the  bases  for  computing  interest  on  loans  made by the
Lenders, and by basing interest payable on the ABR Advances on the BNY Rate, the
Lenders  have not  committed  to  charge,  and the  Borrower  has not in any way
bargained for, interest based on a lower or the lowest rate at which the Lenders
may now or in the future make loans to other borrowers.

     3.2. FEES.

          (a)  TRANCHE  A  COMMITMENT  FEE.  The  Borrower  agrees to pay to the
Administrative  Agent,  for the account of the  Tranche A Lenders in  accordance
with each such Lender's  Tranche A Percentage,  a fee (the "TRANCHE A COMMITMENT
FEE")  during  the  Tranche A  Commitment  Period  equal to the  Commitment  Fee
Percentage  per annum of the  average  daily  unused  portion  of the  Aggregate
Tranche A Commitments.  The Tranche A Commitment Fee shall be payable  quarterly
in arrears on the last day of each March,  June,  September  and December and on
the date of the  expiration or other  termination  of the Tranche A Commitments.
The Commitment Fee shall be calculated on the basis of a 365 or 366-day year for
the actual number of days elapsed.

          (b)  LETTER  OF  CREDIT  FEES.  The  Borrower  agrees  to  pay  to the
Administrative  Agent,  for the account of the  Tranche A Lenders in  accordance
with each such Lender's Tranche A Percentage, commissions (the "LETTER OF CREDIT
FEES") with  respect to the Letters of Credit for the period from and  including
the date of issuance of each thereof through the expiration  date thereof,  at a
rate per annum equal to the Applicable Margin applicable to Letters of Credit on
the average daily maximum  amount  available  under any  contingency to be drawn
under such Letter of Credit.  The Letter of Credit Fees shall be (i)  calculated
on the basis of a 360-day  year for the actual  number of days  elapsed and (ii)
payable quarterly in arrears on the last day of each March, June,  September and
December of each year,  commencing  on the first such day  following  the Second
Restatement  Date, and on the date that the Tranche A Commitments  shall expire.
In  addition to the Letter of Credit  Fees,  the  Borrower  agrees to pay to the
Letter of Credit  Issuer,  for its own account,  its  standard  fees and charges
customarily  charged to customers  similar to the  Borrower  with respect to any
Letter of Credit.

          (c) AGENTS' AND LETTER OF CREDIT ISSUER'S FEES. The Borrower agrees to
pay to the  Agents  and the Letter of Credit  Issuer,  for their own  respective
accounts, such other fees as have been agreed to in writing by the Borrower, the
Letter of Credit Issuer and/or any of the Agents.

     3.3. CONVERSIONS AND CONTINUATIONS.

          (a) The Borrower may elect from time to time to convert its Eurodollar
Advances  to ABR  Advances  by  giving  the  Administrative  Agent at least  one
Business  Day's prior  irrevocable  notice of such  election  (confirmed  by the
delivery of a Notice of  Conversion/Continuation),  specifying  (A) whether such
ABR Advance is to comprise all

                                      -44-
<PAGE>


or a portion of the Tranche A Loans or the Tranche C Loans, (B) the amount to be
so converted and (C) the Interest Period  relating to such Eurodollar  Advances.
In  addition,  the  Borrower  may elect from time to time to (i) convert its ABR
Advances to Eurodollar  Advances and (ii) to continue its Eurodollar Advances by
selecting  a  new  Interest  Period  therefor,   in  each  case  by  giving  the
Administrative  Agent at least three Business Days' prior irrevocable  notice of
such    election    (confirmed    by   the    delivery    of   a    Notice    of
Conversion/Continuation),  in the case of a  conversion  to or  continuation  of
Eurodollar  Advances,  specifying  (A)  whether  such  Eurodollar  Advance is to
comprise all or a portion of the Tranche A Loans or the Tranche C Loans, (B) the
amount to be so converted and (C) the Interest Period relating thereto, provided
that any such  conversion of ABR Advances to Eurodollar  Advances  shall only be
made on a Business Day and any such  conversion  or  continuation  of Eurodollar
Advances shall only be made on the last day of the Interest Period applicable to
the  Eurodollar  Advances which are to be converted to ABR Advances or continued
as new Eurodollar Advances.  The Administrative Agent shall promptly provide the
applicable   Class   of   Lenders   with  a  copy  of  each   such   Notice   of
Conversion/Continuation.  ABR Advances and Eurodollar  Advances may be converted
or  continued  pursuant  to this  Section  in whole or in  part,  provided  that
conversions  of  ABR  Advances  to  Eurodollar   Advances  or  continuations  of
Eurodollar  Advances,  shall be in an aggregate  principal amount of $500,000 or
such  amount  plus a  whole  multiple  of  $100,000.  If,  with  respect  to any
conversion of a Loan from one interest rate basis to another, the Borrower shall
fail to give  due  notice  as  provided  in this  Section,  such  Loan  shall be
automatically  converted to an ABR Advance upon the  expiration  of the Interest
Period with respect thereto.

          (b) Notwithstanding  anything in this Section to the contrary,  no ABR
Advance may be converted to a Eurodollar Advance,  and no Eurodollar Advance may
be continued,  if the Borrower or the Administrative  Agent has knowledge that a
Default or Event of Default has  occurred  and is  continuing  either (i) at the
time the  Borrower  shall  notify the  Administrative  Agent of its  election to
convert or continue or (ii) on the  requested  Conversion/Continuation  Date. In
such event, such ABR Advance shall be automatically  continued as an ABR Advance
or such Eurodollar Advance shall be automatically converted to an ABR Advance on
the last day of the Interest Period applicable to such Eurodollar Advance. If an
Event of Default shall have occurred and be continuing, the Administrative Agent
shall, at the request of the Required Lenders, notify the Borrower (by telephone
or otherwise)  that all, or such lesser amount as the  Administrative  Agent and
the Required Lenders shall  designate,  of the outstanding  Eurodollar  Advances
shall be automatically converted to ABR Advances, in which event such Eurodollar
Advances  shall be  automatically  converted  to ABR  Advances  on the date such
notice is given.  In the event that  Eurodollar  Advances  are  converted to ABR
Advances  at the  request of the  Required  Lenders  pursuant  to the  preceding
sentence,  no Lender shall be entitled to an indemnity  described in Section 3.4
with respect to the Eurodollar Advances so converted.

          (c) Each conversion or  continuation  shall be effected by each member
of the  applicable  Class of Lenders by  applying  the  proceeds  of its new ABR
Advance or Eurodollar  Advance,  as the case may be, to its Advances (or portion
thereof) being converted or continued (it being  understood that such conversion
or  continuation  shall not constitute a borrowing for purposes of Sections 4, 5
or 6).  Accrued  interest on the Advance (or portion  thereof)  being  converted
shall be paid by the Borrower at the time of conversion.


                                      -45-
<PAGE>


          (d) Without in any way  limiting  the  obligation  of the  Borrower to
confirm in writing any telephonic  notice of a conversion or continuation  given
to the Administrative  Agent, the Administrative Agent may act without liability
upon the basis of telephonic notice of such conversion or continuation  believed
by the  Administrative  Agent in good faith to be from an authorized  officer of
the Borrower  prior to receipt of written  confirmation.  In each such case, the
Borrower  waives the right to dispute the  Administrative  Agent's record of the
terms of such telephone notice of such conversion or continuation.

          (e) Except as provided in the last sentence of  subsection  (b) above,
if any  prepayment  is made under this Section  with  respect to any  Eurodollar
Advances,  in whole or in part, prior to the last day of the applicable Interest
Period,  the Borrower agrees to indemnify the Lenders in accordance with Section
3.4.

     3.4. FUNDING LOSS

          (a) Notwithstanding  anything contained herein to the contrary, if the
Borrower shall fail to borrow or convert or continue on a Credit  Extension Date
or Conversion/Continuation Date after the Borrower shall have given notice to do
so in which it shall have  requested a  Eurodollar  Advance  pursuant to Section
2.2(a) or 3.3 or if a  Eurodollar  Advance  shall be  terminated  for any reason
(subject to the penultimate  sentence of Section 3.3(b)),  prior to the last day
of the Interest Period applicable  thereto, or if, while a Eurodollar Advance is
outstanding,  any repayment or prepayment of such Eurodollar  Advance is made or
deemed  made for any  reason  (including,  without  limitation,  as a result  of
acceleration  or  illegality)  on a date  which  is prior to the last day of the
Interest Period applicable thereto, the Borrower agrees to indemnify each Lender
against,  and to pay directly to such Lender within ten days after such Lender's
demand therefor, any loss or expense suffered by such Lender as a result of such
failure to borrow,  termination or repayment,  including without limitation,  an
amount, if greater than zero, equal to:

                             A  x   (B-C) x  D__
                                             360

where:

"A" equals such Lender's pro rata share of the Affected Principal Amount;

"B" equals the  Eurodollar  Rate  (expressed  as a decimal)  applicable  to such
Advance;

"C" equals the applicable  Eurodollar Rate (expressed as a decimal) in effect on
or about the first day of the applicable Remaining Interest Period, based on the
applicable rates offered or bid on or about such date, for deposits in an amount
equal  approximately  to such Lender's pro rata share of the Affected  Principal
Amount with an Interest Period equal  approximately to the applicable  Remaining
Interest Period, as determined by the Administrative Agent;

"D" equals the number of days from and including the first day of the applicable
Remaining  Interest  Period  to but  excluding  the last  day of such  Remaining
Interest Period;

and any other  out-of-pocket loss or expense (including any internal  processing
charge  customarily   charged  by  such  Lender)  suffered  by  such  Lender  in
liquidating or employing

                                      -46-
<PAGE>


deposits  acquired to fund or maintain  the  funding of the  Affected  Principal
Amount,  or redeploying  funds prepaid or repaid, in amounts which correspond to
such Lender's pro rata share of such proposed borrowing, conversion,  terminated
Eurodollar  Advance,   prepayment  or  repayment.   Each  determination  by  the
Administrative  Agent or a Lender  pursuant to this Section  shall be conclusive
and binding on the Borrower  absent  manifest  error.  Each Lender has indicated
that,  if the  Borrower  elects to borrow or convert to or  continue  Eurodollar
Advances, such Lender may wish to purchase one or more deposits in order to fund
or maintain its funding of its Eurodollar Advances during the Interest Period in
question;  it being understood that the provisions of this Agreement relating to
such  funding  are  included  only for the  purpose of  determining  the rate of
interest to be paid on such Eurodollar  Advances and for purposes of determining
amounts  owing under  Sections  3.5(a) and 3.6. Each Lender shall be entitled to
fund and maintain its funding of all or any part of each Eurodollar Advance made
by it in any manner it sees fit, but all such determinations shall be made as if
such Lender had actually  funded and maintained  its funding of such  Eurodollar
Advance during the applicable  Interest  Period through the purchase of deposits
in  an  amount  equal  to  such   Eurodollar   Advance  and  having  a  maturity
corresponding to such Interest Period.

     3.5. INCREASED COSTS; ILLEGALITY, ETC.

          (a) INCREASED COSTS. If any Change in Law shall impose, modify or make
applicable any reserve, special deposit, compulsory loan, assessment,  increased
cost or similar  requirement against assets held by, or deposits of, or advances
or loans by, or other credit extended by, or any other  acquisition of funds by,
any office of any Credit Party in respect of its  Eurodollar  Advances  which is
not otherwise  included in the determination of a Eurodollar Rate or against any
Letters of Credit  issued  hereunder  and the result  thereof is to increase the
cost to any Credit Party of making,  renewing,  converting  or  maintaining  its
Eurodollar  Advances or its commitment to make such Eurodollar  Advances,  or to
reduce  any  amount  receivable  under  the Loan  Documents  in  respect  of its
Eurodollar  Advances,  or to increase the cost to any Credit Party of issuing or
maintaining the Letters of Credit or participating  therein, as the case may be,
or the cost to any Credit Party of performing its respective functions hereunder
with  respect to the Letters of Credit,  then,  in any such case,  the  Borrower
shall  pay such  Credit  Party  such  additional  amounts  as is  sufficient  to
compensate  such Credit  Party for such  additional  cost or  reduction  in such
amount  receivable which such Credit Party deems to be material as determined by
such Credit Party.

          (b) CAPITAL  ADEQUACY.  If any Credit Party determines that any Change
in Law relating to capital requirements has or would have the effect of reducing
the rate of return on such  Credit  Party's  capital  or on the  capital of such
Credit Party's holding  company,  if any, on the Extensions of Credit to a level
below that which such Credit Party (or its holding  company) would have achieved
or would  thereafter be able to achieve but for such Change in Law (after taking
into account such Credit Party's (or such holding company's)  policies regarding
capital adequacy),  the Borrower shall pay to such Credit Party (or such holding
company) such additional  amount or amounts as will compensate such Credit Party
(or such holding company) for such reduction.

          (c) ILLEGALITY.  Notwithstanding  any other provision  hereof,  if any
Lender shall reasonably determine that any law, regulation, treaty or directive,
or any change therein or in the  interpretation  or application  thereof,  shall
make it unlawful for such Lender to make or maintain any  Eurodollar  Advance as
contemplated by this  Agreement,  such Lender shall promptly notify the Borrower
and the Administrative Agent thereof, and

(i) the  commitment of such Lender to make such  Eurodollar  Advances or convert
ABR Advances to Eurodollar  Advances  shall  forthwith be  suspended,  (ii) such
Lender  shall fund its portion of each  requested  Eurodollar  Advance as an ABR
Advance  and (iii) such  Lender's  Loans  then  outstanding  as such  Eurodollar
Advances,  if any, shall be converted  automatically to ABR Advances on the last
day of the then current  Interest Period  applicable  thereto or at such earlier
time as may be required by law. The  commitment  of any such Lender with respect
to  Eurodollar  Advances  shall be suspended  until such Lender shall notify the
Administrative  Agent  and the  Borrower  that the  circumstances  causing  such
suspension  no  longer  exist.  Upon  receipt  of  such  notice  by  each of the
Administrative  Agent and the  Borrower,  such  Lender's  commitment  to make or
maintain Eurodollar Advances shall be reinstated.

          (d)   SUBSTITUTED   INTEREST   RATE.   In  the  event   that  (i)  the
Administrative  Agent  shall  have  determined  (which  determination  shall  be
conclusive  and  binding  upon the  Borrower)  that by reason  of  circumstances
affecting the interbank  eurodollar  market either adequate and reasonable means
do not exist for ascertaining the Eurodollar Rate applicable pursuant to Section
3.1 or (ii) the Required  Lenders shall have notified the  Administrative  Agent
that they have determined (which  determination  shall be conclusive and binding
on the Borrower)  that the  applicable  Eurodollar  Rate will not adequately and
fairly  reflect the cost to such Lenders of maintaining or funding loans bearing
interest based on such Eurodollar Rate, with respect to any portion of the Loans
that the Borrower has  requested be made as  Eurodollar  Advances or  Eurodollar
Advances that will result from the requested  conversion or  continuation of any
portion of the  Advances  into or of  Eurodollar  Advances  (each,  an "AFFECTED
Advance"),  the Administrative  Agent shall promptly notify the Borrower and the
Lenders (by telephone or otherwise, to be promptly confirmed in writing) of such
determination,  on or, to the extent practicable,  prior to the requested Credit
Extension  Date  or  Conversion  Date  for  such  Affected   Advances.   If  the
Administrative  Agent shall give such notice, (a) any Affected Advances shall be
made as ABR  Advances,  (b) the Advances (or any portion  thereof)  that were to
have been converted to Affected  Advances shall be converted to ABR Advances and
(c) any outstanding Affected Advances shall be converted, on the last day of the
then current  Interest Period with respect thereto,  to ABR Advances.  Until any
notice under clauses (i) or (ii), as the case may be, of this subsection (d) has
been withdrawn by the  Administrative  Agent (by notice to the Borrower promptly
upon  either  (x)  the   Administrative   Agent  having   determined  that  such
circumstances affecting the interbank eurodollar market no longer exist and that
adequate and  reasonable  means do exist for  determining  the  Eurodollar  Rate
pursuant to Section 3.1 or (y) the Administrative  Agent having been notified by
such Required  Lenders that  circumstances no longer render the Advances (or any
portion thereof) Affected  Advances),  no further  Eurodollar  Advances shall be
required to be made by the  Lenders,  nor shall the  Borrower  have the right to
convert all or any portion of the Loans to or as Eurodollar Advances.

          (e) PAYMENT; CERTIFICATES. Each payment pursuant to subsections (a) or
(b) above shall be made within 10 days after demand therefor, which demand shall
be  accompanied  by a  certificate  of the Credit Party  demanding  such payment
setting  forth the  calculations  of the  additional  amounts  payable  pursuant
thereto.  Each such  certificate  shall be conclusive  absent manifest error. No
failure by any Credit Party to demand,  and no delay in demanding,  compensation
for any  increased  cost shall  constitute  a waiver of its right to demand such
compensation  at any time,  provided  that such Credit  Party  shall  notify the
Borrower  of any such  increased  cost  within 90 days after the officer of such
Lender having primary  responsibility  for this Agreement has obtained knowledge
of such increased cost.

     3.6. TAXES.

          (a)  PAYMENTS  FREE OF TAXES.  All  payments  by or on  account of the
Borrower  under any Loan  Document to or for the account of a Credit Party shall
be made free and clear of, and without any  deduction or  withholding  for or on
account  of, any and all  present or future  Indemnified  Taxes or Other  Taxes,
provided that if the Borrower or any other Person is required by any law,  rule,
regulation,  order,  directive,  treaty or  guideline  to make any  deduction or
withholding  in  respect  of such  Indemnified  Tax or Other Tax from any amount
required to be paid by the  Borrower  to or on behalf of any Credit  Party under
any Loan Document  (each,  a "REQUIRED  PAYMENT"),  then (i) the Borrower  shall
notify the Administrative Agent and such Credit Party of any such requirement or
any  change  in any  such  requirement  as soon as the  Borrower  becomes  aware
thereof,  (ii) the Borrower shall pay such Indemnified Tax or Other Tax prior to
the date on which  penalties  attach  thereto,  such  payment to be made (to the
extent that the liability to pay is imposed on the Borrower) for its own account
or (to the extent that the  liability to pay is imposed on such Credit Party) on
behalf and in the name of such Credit  Party,  (iii) the  Borrower  shall pay to
such Credit Party an additional amount such that such Credit Party shall receive
on the due date  therefor an amount  equal to the  Required  Payment had no such
deduction or  withholding  been made or required,  and (iv) the Borrower  shall,
within 30 days after paying such  Indemnified  Tax or Other Tax,  deliver to the
Administrative Agent and such Credit Party satisfactory evidence of such payment
to the relevant Governmental Body.

          (b)  REIMBURSEMENT FOR TAXES AND OTHER TAXES PAID BY CREDIT PARTY. The
Borrower shall reimburse each Credit Party, within ten days after written demand
therefor,  for the full amount of all  Indemnified  Taxes or Other Taxes paid by
such  Credit  Party on or with  respect  to any  payment by or on account of any
obligation of the Borrower under the Loan Documents (including Indemnified Taxes
or Other Taxes imposed or asserted on or  attributable  to amounts payable under
this  Section) and any  penalties,  interest  and  reasonable  expenses  arising
therefrom or with respect  thereto (other than any such  penalties,  interest or
expenses  that are  incurred  by such  Credit  Party's  unreasonably  taking  or
omitting to take action with respect to such Indemnified  Taxes or Other Taxes),
whether or not such  Indemnified  Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant  Governmental  Body. A certificate as to the
amount of such payment or liability  delivered to the Borrower by a Credit Party
shall be conclusive  absent  manifest  error. In the event that any Credit Party
determines  that it received a refund or credit for  Indemnified  Taxes or Other
Taxes paid by the Borrower under this Section,  such Credit Party shall promptly
notify the  Borrower of such fact and shall remit to the  Borrower the amount of
such refund or credit.

          (c) FOREIGN CREDIT PARTIES.  Any Foreign Credit Party that is entitled
to an  exemption  from or  reduction  of  withholding  tax  under the law of the
jurisdiction  in which the  Borrower  is  located,  or any  treaty to which such
jurisdiction is a party, with respect to payments under the Loan Documents shall
deliver to the Borrower (with a copy to the  Administrative  Agent), at the time
or times  prescribed  by applicable  law,  such properly  completed and executed
documentation prescribed by applicable law (including Internal Revenue Form 4224
or Form 1001) or  reasonably  requested  by the  Borrower  as will  permit  such
payments to be made without withholding or at a reduced rate.

     3.7. MITIGATION; REPLACEMENT LENDERS.

          (a) CHANGES OF LENDING  OFFICES.  If any Credit  Party (or its holding
company,  if any) requests  compensation  under Section  3.5(a) or (b) or if the
Borrower  is  required to pay an  additional  amount to any Credit  Party or any
Governmental  Body for the account of any Credit Party  pursuant to Section 3.6,
such Credit Party will, upon the request of the Borrower, use reasonable efforts
(subject to its overall policy  considerations) to designate a different lending
office for funding or booking its  Extensions  of Credit or to assign its rights
and obligations hereunder to another of its offices, branches or affiliates, if,
in its good faith judgment,  such  designation or assignment (i) would eliminate
or reduce future amounts  payable under Section 3.5(a) or (b) or Section 3.6, as
the case may be, (ii) would not subject  such Credit  Party to any  unreimbursed
cost or expense and (iii) would not otherwise be disadvantageous to such Lender.
The  Borrower  agrees to pay the  reasonable  costs  and  expenses  incurred  in
connection with any such designation or assignment and the Administrative  Agent
agrees that no  assignment  fee shall be payable to it pursuant to Section 12 in
connection  therewith.  Nothing in this Section  shall affect or postpone any of
the obligations of the Borrower to make the payments  required to a Credit Party
under  Section  3.5(a)  or  (b) or  Section  3.6,  incurred  prior  to any  such
designation or assignment.

          (b)  REPLACEMENT  OF LENDERS.  If (i) any Credit Party (or its holding
company,  if any) requests  compensation  under Section  3.5(a) or (b) or if the
Borrower  is  required to pay an  additional  amount to any Credit  Party or any
Governmental Body for the account of any Credit Party pursuant to Section 3.6 in
an  aggregate  amount in excess of $50,000,  or (ii) any Credit Party shall give
any notice to the  Borrower  or the  Administrative  Agent  pursuant  to Section
3.5(c),  then, in each such case,  provided that no Default shall then exist and
be continuing,  during the 90 day period after the receipt of such request,  the
Borrower  at  its  sole  cost,  expense  and  effort  may,  upon  notice  to the
Administrative  Agent and the Letter of Credit Issuer,  require Lender to assign
(in accordance with and subject to the  restrictions  contained in Section 11.5)
all of its rights and  obligations  under the Loan Documents to any other Lender
(or affiliate  thereof),  or any other  Eligible  Institution  identified by the
Borrower  if  such  other  Lender  (or  affiliate   thereof)  or  such  Eligible
Institution  agrees  to  assume  all of  the  obligations  of  such  Lender  for
consideration  equal to the outstanding  principal amount of such Lender's Loans
and all unreimbursed  sums paid by such Lender under Section 2.6,  together with
interest  thereon to the date of such  transfer  and all other  amounts  payable
under the Loan Documents to such Lender on or prior to the date of such transfer
(including  any fees accrued  hereunder  and any amounts  which would be payable
under Section 3.4 as if all of such Lender's Loans were being prepaid in full on
such  date).  In the  event of a  transfer  to any other  Eligible  Institution,
subject to the  satisfaction  of the  conditions of Section 11.5,  such Eligible
Institution shall be a "Lender" for all purposes hereunder. Without prejudice to
the survival of any other agreement of the Borrower hereunder, the agreements of
the  Borrower  contained  in Sections  3.5,  3.6(b),  11.1(a) and 11.4  (without
duplication  of any  payments  made to such Lender by the Borrower or such other
Eligible Institution) shall survive for the benefit of any Lender replaced under
this Section with respect to the time prior to such  replacement.  In connection
with any transfer  pursuant to this subsection,  the Borrower shall be obligated
to pay the assignment fee referred to in Section 11.5(b).

4.   REPRESENTATIONS AND WARRANTIES 

     In order to induce the Credit  Parties  to enter  into this  Agreement  and
extend or participate in the Extensions of Credit provided herein,  the Borrower
hereby makes the following representations and warranties to each Credit Party:

     4.1. SUBSIDIARIES; CAPITALIZATION.

          As of the  Second  Restatement  Date and  after  giving  effect to the
consummation of the  Transactions,  Arch has only the  Subsidiaries set forth on
Schedule 4.1. The issued and outstanding shares of each corporate  Subsidiary of
Arch are duly authorized,  validly issued,  fully paid and nonassessable and are
owned free and clear of any Liens,  except Permitted Liens. The interest of Arch
and any of its Subsidiaries in each of its  non-corporate  Subsidiaries is owned
free and clear of any Liens,  except Permitted  Liens.  The outstanding  capital
Stock of each  corporate  Subsidiary of Arch and the ownership  interest in each
non-corporate  Subsidiary  of Arch,  in each case as of the  Second  Restatement
Date, are as set forth on Schedule 4.1. The owner of each such interest and each
issue of capital Stock listed on Schedule 4.1 is the  registered  and beneficial
owner thereof.  None of the Borrower or any of its  Subsidiaries  has issued any
securities  convertible  into capital Stock (or other equity interest) and there
are no outstanding options or warrants to purchase capital Stock of the Borrower
or any such Subsidiary of any class or kind, and there are no agreements, voting
trusts or  understandings  with  respect  thereto or affecting in any manner the
sale, pledge,  assignment or other disposition  thereof,  including any right of
first refusal,  option,  redemption,  call or other rights with respect thereto,
whether  similar or dissimilar to any of the foregoing.  In addition,  as of the
Second  Restatement Date, Arch Canada is the only Foreign Subsidiary of Arch and
is not a Material Foreign Subsidiary.

     4.2. EXISTENCE AND POWER.

          The Borrower and each of its  Subsidiaries is duly organized,  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
incorporation  or formation,  has all requisite legal power and authority to own
its  Property  and to carry on its  business  as now  conducted,  and is in good
standing and authorized to do business in each jurisdiction in which the failure
to be so  authorized  could  reasonably  be expected to have a Material  Adverse
Effect.

     4.3. AUTHORITY AND EXECUTION.

          The  Borrower  and each of its  Subsidiaries  has full legal power and
authority  to enter  into,  execute,  deliver  and  carry  out the  terms of the
Transaction  Documents to which it is a party, and, in the case of the Borrower,
to make the borrowings  contemplated  hereby, to execute,  deliver and carry out
the terms of the Notes and to incur the obligations provided for therein, all of
which have been duly  authorized by all proper and  necessary  action and are in
full compliance with its Organizational  Documents. The Borrower and each of its
Subsidiaries has duly executed and delivered the Transaction  Documents to which
it is a party.

     4.4. GOVERNMENTAL BODY APPROVALS.

          Except as set forth on Schedule  4.4, no  consent,  authorizations  or
approval  of,  filing  with,  notice  to, or  exemption  by,  stockholders,  any
Governmental Body or any

                                      -51-
<PAGE>


other  Person  (except  for those  which have been  obtained,  made or given) is
required to authorize, or is required in connection with the execution, delivery
and  performance  by the  Borrower  and each of its  Subsidiaries  of any of the
Transaction  Documents  to which it is a party or is required as a condition  to
the validity or enforceability of any of the Transaction Documents. No provision
of any applicable statute,  law (including any applicable usury or similar law),
rule or regulation of any Governmental Body will prevent the execution, delivery
or performance of, or affect the validity of, any of the Transaction Documents.

     4.5. BINDING AGREEMENT.

          The Transaction Documents  constitute,  and the Notes, when issued and
delivered  pursuant hereto for value received,  will  constitute,  the valid and
legally  binding  obligations of the Borrower and each of its  Subsidiaries,  in
each case to the extent that it is a party  thereto,  enforceable  in accordance
with their respective  terms,  except as such  enforceability  may be limited by
applicable  bankruptcy,   insolvency,   reorganization  or  other  similar  laws
affecting the enforcement of creditors' rights generally.

     4.6. LITIGATION.

          Except as set forth on Schedule  4.6,  there are no actions,  suits or
proceedings at law or in equity or by or before any  Governmental  Body (whether
or not  purportedly on behalf of the Borrower or any of its  Subsidiaries or any
other Loan  Party)  pending or, to the  knowledge  of the  Borrower,  threatened
against the Borrower or any of its  Subsidiaries  or any other Loan Party or any
of their  respective  Properties or rights,  which (i) if adversely  determined,
could reasonably be expected to have a Material Adverse Effect or (ii) call into
question the validity or enforceability of any of the Transaction Documents.

     4.7. NO CONFLICTING AGREEMENTS.

          Except as set forth on Schedule  4.7,  neither the Borrower nor any of
its  Subsidiaries  is  in  default  under  any  mortgage,  indenture,  contract,
agreement,  judgment,  decree  or order to which it is a party or by which it or
any of its Property is bound, which defaults, taken as a whole, could reasonably
be  expected  to have a Material  Adverse  Effect.  The  execution,  delivery or
carrying out of the terms of the  Transaction  Documents  will not  constitute a
default  under,  conflict  with,  require any consent under (other than consents
which  have been  obtained)  or  result in the  creation  or  imposition  of, or
obligation  to create,  any Lien upon the Property of the Borrower or any of its
Subsidiaries  pursuant to the terms of any such mortgage,  indenture,  contract,
agreement, judgment, decree or order, which defaults, conflicts and consents, if
not obtained,  taken as a whole, could reasonably be expected to have a Material
Adverse Effect. The execution, delivery or carrying out of the terms of the Loan
Documents  will not  constitute  a default  under,  conflict  with,  require any
consent under (other than consents which have been obtained),  the  Subordinated
Indenture,  the Parent  Discount  Notes  Indenture,  either of the Existing Arch
Indentures  or the  Arch  12  3/4%  Indenture,  oR  result  in the  creation  or
imposition of, or obligation to create,  any Lien (other than  Permitted  Liens)
upon  the  Property  of  the  Parent  or  Arch  pursuant  to  the  terms  of the
Subordinated  Indenture,  the Parent  Discount  Notes  Indenture,  either of the
Existing Arch Indentures or the Arch 12 3/4% Indenture.


                                      -52-
<PAGE>


     4.8. TAXES.

          Each of the Borrower and each of its  Subsidiaries has filed or caused
to be filed all tax  returns  required  to be filed  and has  paid,  or has made
adequate  provision for the payment of, all taxes shown to be due and payable on
said  returns or in any  assessments  made  against it (other  than those  being
contested as required under Section 7.4) which would be material to the Borrower
or any of its  Subsidiaries,  and no tax Liens  have  been  filed  with  respect
thereto  except  Permitted  Liens  described  in Section  8.2(i).  The  charges,
accruals and reserves on the books of the Borrower and each of its  Subsidiaries
with  respect to all  federal,  state,  local and other  taxes are,  to the best
knowledge of the Borrower,  adequate for the payment of all such taxes,  and the
Borrower does not know of any unpaid assessment which is due and payable against
it or  any  of its  Subsidiaries  or  any  claims  being  asserted  which  could
reasonably be expected to have a Material Adverse Effect, except such thereof as
are being  contested  as required  under  Section  7.4,  and for which  adequate
reserves have been set aside in accordance with GAAP.

     4.9. COMPLIANCE WITH APPLICABLE LAWS.

          Neither the  Borrower nor any of its  Subsidiaries  is in default with
respect to any  judgment,  order,  writ,  injunction,  decree or decision of any
Governmental  Body which default could reasonably be expected to have a Material
Adverse  Effect.  The Borrower and each of its  Subsidiaries is complying in all
material   respects  with  all  applicable   statutes  and  regulations  of  all
Governmental  Bodies,  including  ERISA and  Environmental  Laws, a violation of
which could reasonably be expected to have a Material Adverse Effect.

     4.10. INVESTMENT COMPANIES AND OTHER REGULATED ENTITIES.

          Neither  the  Borrower,   any  of  its  Subsidiaries  nor  any  Person
controlled by, controlling, or under common control with, the Borrower or any of
its  Subsidiaries,  is (i) an "investment  company" as defined in, or subject to
regulation  under,  the  Investment  Company  Act of 1940,  as  amended,  (ii) a
"holding  company" as defined  in, or subject to  regulation  under,  the Public
Utility  Holding  Company Act of 1935 or the Federal  Power Act, as amended,  or
(iii)  subject to any statute or  regulation  which  prohibits or restricts  the
incurrence of Indebtedness for borrowed money, including statutes or regulations
relative to common or  contract  carriers  or to the sale of  electricity,  gas,
steam, water, telephone, telegraph or other public utility services.

     4.11. PROPERTIES.

          Each  of the  Borrower  and  each of its  Subsidiaries  has  good  and
marketable title to, or valid leasehold interests in, all of its property,  real
and personal,  material to its business,  subject to no Liens,  except Permitted
Liens and except  for minor  defects  in title  that do not  interfere  with its
ability to conduct  its  business  as  currently  conducted  or to utilize  such
properties for their intended purposes.

     4.12. FCC MATTERS.

          The  Borrower  and each of its  Subsidiaries  (i) has duly and  timely
filed all filings which are required to be filed by it under the  Communications
Act,  the  failure  to file of which  could  reasonably  be  expected  to have a
Material Adverse Effect and (ii) is in all material  respects in compliance with
the Communications Act, including the rules and

                                      -53-
<PAGE>


regulations of the FCC relating to the carriage of radio common carrier signals,
the failure to be in compliance with which could  reasonably be expected to have
a Material Adverse Effect.

     4.13. FEDERAL RESERVE REGULATIONS.

          (a) Neither the Borrower nor any Subsidiary is engaged principally, or
as one of its important activities,  in the business of extending credit for the
purpose of purchasing or carrying any Margin Stock.  After giving effect to each
Transaction  and the  making of each  Extension  of  Credit,  Margin  Stock will
constitute less than 25% of the assets (as determined by any reasonable  method)
of the Borrower and the Subsidiaries.

          (b) No part of the  proceeds of any  Extension of Credit will be used,
whether  directly  or  indirectly,  and  whether  immediately,  incidentally  or
ultimately, for any purpose that entails a violation of, or that is inconsistent
with, the provisions of Regulation U or X.

     4.14. TARIFFS.

          No action to change, alter, rescind or otherwise terminate the tariffs
containing service regulations or any rates and charges for radio common carrier
services which, if adversely  determined,  would have a Material Adverse Effect,
is  pending  or known by the  Borrower  or any of its  Subsidiaries  to be under
consideration.

     4.15. NO MISREPRESENTATION.

          No representation  or warranty  contained herein and no certificate or
report furnished or to be furnished pursuant to any of the Transaction Documents
by any Loan  Party in  connection  with the  transactions  contemplated  thereby
contains  or will  contain a  misstatement  of  material  fact,  or, to the best
knowledge of the Borrower,  omits or will omit to state a material fact required
to be stated in order to make the  statements  herein or therein  contained  not
misleading in the light of the  circumstances  under which made. With respect to
projections or pro-forma financial  statements  furnished by the Borrower or any
of its  Subsidiaries,  such  projections  have been or will be  prepared in good
faith on the assumptions  stated therein,  which assumptions are or will be fair
and reasonable in light of the circumstances existing at the time of delivery of
such  projections  or statements  and  represent,  at the time of delivery,  the
Borrower or such Subsidiary's best estimate of its future financial performance.

     4.16. PLANS.

          None  of  the  Borrower,  any  of its  Subsidiaries  or  any  Commonly
Controlled Entity maintains or is obligated to contribute to any Single Employer
Plan or Multiemployer  Plan.  Since the effective date of ERISA,  there have not
been,  nor are there now existing,  any events or conditions  which would permit
any Single  Employer Plan at any time  maintained  by the  Borrower,  any of its
Subsidiaries or any Commonly  Controlled Entity or, to the best knowledge of the
Borrower,  any Multiemployer Plan to which the Borrower, any of its Subsidiaries
or any Commonly Controlled Entity at any time contributed to be terminated under
circumstances which would cause the Lien provided under Section 4068 of ERISA to
attach to the Property of the Borrower or any of its Subsidiaries.


                                      -54-
<PAGE>


     4.17. BURDENSOME OBLIGATIONS.

          Neither  the  Borrower  nor any of its  Subsidiaries  is a party to or
bound by any franchise,  agreement,  deed, lease or other instrument, or subject
to any legal restriction which, in the opinion of the management of the Borrower
or such Subsidiary, is so unusual or burdensome, in the context of its business,
as in the foreseeable future might materially and adversely affect or impair the
revenue of the Borrower and its Subsidiaries taken as a whole, or Operating Cash
Flow, or the ability of the Borrower or any of its Subsidiaries to perform their
respective obligations under the Loan Documents. The Borrower does not presently
anticipate that future  expenditures by the Borrower or any of its  Subsidiaries
needed to meet the  provisions of federal or state  statutes,  orders,  rules or
regulations  will be so  burdensome  as to affect  or  impair,  in a  materially
adverse  manner,  the  business or  condition,  financial or  otherwise,  of the
Borrower and its Subsidiaries taken as a whole.

     4.18. FINANCIAL STATEMENTS.

          (a) The Parent and Arch have heretofore furnished to each Credit Party
a copy of their  respective  (A) Forms 10-K for the fiscal year ending  December
31, 1997,  containing the audited  Consolidated balance sheets of the Parent and
its Subsidiaries and of Arch and its Subsidiaries,  respectively, as of December
31, 1996 and December  31,  1997,  and the related  Consolidated  statements  of
operations,  stockholder's equity and cash flows for the periods then ended, and
(B) Forms 10-Q for the fiscal  quarter  ended  March 31,  1998,  containing  the
unaudited  Consolidated balance sheets of the Parent and its Subsidiaries and of
Arch and its Subsidiaries,  respectively, for such fiscal quarter, together with
the related Consolidated  statements of operations and cash flows for the fiscal
quarter then ended.  Such financial  statements  present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Parent, Arch, the Borrower and their consolidated  Subsidiaries as of such dates
and for such  periods  in  accordance  with  GAAP,  subject  to  year-end  audit
adjustments and the absence of footnotes in the case of the quarterly statements
referred to above. Except as fully reflected in such financial statements, there
are no material  liabilities or  obligations  with respect to Arch or any of its
Subsidiaries of any nature whatsoever (whether absolute, contingent or otherwise
and whether or not due).

          (b) Since December 31, 1997, except for the Transactions,  each of the

Property of the Borrower or such  Subsidiary  not  permitted  under Section 8.2,
unless and to the extent only that such  taxes,  assessments,  charges,  license
fees and levies shall be contested in good faith and by appropriate  proceedings
diligently  conducted by the Borrower or such  Subsidiary  and provided that any
such  contested  Tax,  assessment,   charge,  license  fee  or  levy  shall  not

insurance with  financially  sound  insurance  carriers on such of its Property,
against  at least  such  risks,  and in at least such  amounts,  as are  usually
insured  against  by similar  businesses,  and  which,  in the case of  property
insurance,  shall be in amounts sufficient to prevent the Borrower from becoming
a  co-insurer,  and  which  shall be on  terms  reasonably  satisfactory  to the
Administrative  Agent,  and file with the  Administrative  Agent  within 10 days
after request therefor a detailed list of such insurance then in effect, stating
the names of the carriers thereof,  the policy numbers, the insureds thereunder,

<PAGE>


damage to Property of others,  all such  insurance  being in amounts equal to no
less than that customarily  carried by companies engaged in similar  businesses,
which insurance shall be on terms reasonably  satisfactory to the Administrative
Agent. Promptly upon request therefor,  the Borrower will deliver or cause to be
delivered to the  Administrative  Agent originals or duplicate  originals of all
such policies of insurance.  All such  insurance  policies  shall be endorsed to
provide  that,  in respect of the  interests of the  Collateral  Agent:  (i) the
Collateral  Agent shall be an  additional  insured and, with respect to property
insurance,  sole loss payee in respect of each claim  relating to such  tangible
personal  Property and  resulting in a payment under any such  insurance  policy
exceeding $250,000,  (ii) thirty days' prior written notice of any cancellation,
reduction of amounts  payable,  or any changes and amendments  shall be given to
the Collateral Agent, except that ten days' prior written notice of cancellation
shall be given to the Collateral Agent if cancellation  results from the failure
to pay premiums,  and (iii) the Collateral  Agent shall have the right,  but not
the obligation,  to pay any premiums due or to acquire other such insurance upon
the failure of the Borrower or such  Subsidiary to pay the same or to so insure.

agrees,  promptly upon its receipt  thereof,  to pay over to the Borrower or the
appropriate  Subsidiary  the  proceeds of such payment to enable the Borrower or
such  Subsidiary  to repair,  restore or replace  the  Property  subject to such
claim.  To the extent  that the  Borrower or such  Subsidiary  does not elect to
repair,  restore or replace such Property, an amount equal to the proceeds which
are not employed to repair, restore or replace such Property shall be applied as
required  by Section  2.4.  If a Default or Event of Default  shall  exist,  the
Administrative  Agent or, if applicable  pursuant to the  applicable  Collateral
Document,  the  Collateral  Agent,  shall hold the  proceeds of such  payment as
Collateral  (to the extent of its security  interest in such Property) and apply
such proceeds in accordance with the provisions thereof.

          (c)  CONCURRENT  INSURANCE.  Neither  the  Borrower  nor  any  of  the
Subsidiaries   shall  take  out  separate   insurance   concurrent  in  form  or
contributing  in the event of loss with that required to be maintained  pursuant
to subsection (b) above unless the Administrative Agent has approved the carrier
and the form and content of the insurance policy, including, without limitation,
naming  of the  Collateral  Agent as  additional  insured  and sole  loss  payee
thereunder.

     7.6. PAYMENT OF INDEBTEDNESS AND PERFORMANCE OF OBLIGATIONS.

          Pay and discharge when due, and cause each of its  Subsidiaries  so to
do, all lawful  Indebtedness,  obligations  and claims for labor,  materials and
supplies  or  otherwise  which,  if unpaid,  might (i) have a  Material  Adverse
Effect,  or (ii)  become  a Lien  upon  the  Property  of the  Borrower  or such
Subsidiary  other than a Permitted Lien,  unless and to the extent only that the
validity of such  Indebtedness,  obligation  or claim shall be contested in good
faith and by  appropriate  proceedings  diligently  conducted by the Borrower or
such Subsidiary, and that any such contested Indebtedness, obligations or claims
shall not constitute,  or create,  a Lien on any Property of the Borrower or any
of its Subsidiaries senior to any Lien granted to the Administrative Agent under
the  Collateral  Documents  on such  Property,  and  further  provided  that the
Borrower shall give the  Administrative  Agent prompt notice of any such contest
and that such reserve or other appropriate provision as shall be required by the
Accountants in accordance with GAAP shall have been made therefor.

requirements of all Governmental  Bodies, which now or at any time hereafter may
be  applicable  to the Borrower or such  Subsidiary,  a violation of which could
reasonably be expected to have a Material Adverse Effect, except such thereof as
shall be  contested  in good  faith and by  appropriate  proceedings  diligently
conducted by the Borrower or such  Subsidiary,  provided that the Borrower shall
give the Administrative  Agent and the Lenders prompt notice of such contest and
that such  reserve or other  appropriate  provision  as shall be required by the
Accountants in accordance with GAAP shall have been made therefor.

the Collateral  Agent's option,  all other filings and to give all other notices
as it shall reasonably deem necessary with respect to any of the Collateral, all
of which may be done with or without the signature of the Borrower or any of its
Subsidiaries.  The foregoing power  constitutes a power coupled with an interest
which shall survive until all of the  obligations  under the Loan Documents have
been  indefeasibly  paid  in  full in cash  and  the  Credit  Agreement  and the

Subsidiaries  interface)  required  as a result of the Year 2000 Issue to permit
the proper functioning of such computer systems and other equipment and

or percentage of the Lenders as shall be necessary  under the  circumstances  as
provided  in  Section  11.1) or in the  absence of its own gross  negligence  or

and to have been signed or sent by the proper Person. The  Administrative  Agent
also may rely upon any statement  made to it orally or by telephone and believed
by it to be made by the proper  Person,  and shall not incur any  liability  for
relying thereon.  The  Administrative  Agent may consult with legal counsel (who

exercise  its  rights  and  powers  by or  through  any one or  more  sub-agents
appointed by the  Administrative  Agent,  provided that no such delegation shall
serve as a release of the Administrative  Agent or waiver by the Borrower of any
rights hereunder.  The  Administrative  Agent and any such sub-agent may perform
any and all its  duties  and  exercise  its  rights  and  powers  through  their
respective Related Parties. The exculpatory  provisions of this Section 10 shall

Administrative  Agent as provided in this Section,  the Administrative Agent may
resign at any time by  notifying  the  Lenders and the  Borrower.  Upon any such
resignation, the Required Lenders shall have the right, with the written consent
of the  Borrower  (such  consent not to be  unreasonably  withheld and not to be
required  during the continuance of an Event of Default) to appoint a successor.
If no successor  shall have been so appointed by the Required  Lenders and shall
have accepted such appointment within 30 days after the retiring  Administrative
Agent gives notice of its resignation,  then the retiring  Administrative  Agent
may, on behalf of the Lenders,  appoint a successor  Administrative  Agent which

Agent, and the retiring Administrative Agent shall be discharged from its duties
and  obligations  hereunder.  The fees  payable by the  Borrower  to a successor
Administrative  Agent  shall  be the same as those  payable  to its  predecessor
unless  otherwise  agreed  between the  Borrower and such  successor.  After the
Administrative Agent's resignation hereunder,  the provisions of this Section 10
and  Section  11.4 shall  continue  in effect for the  benefit of such  retiring

reliance  upon the  Administrative  Agent or any other Credit Party 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  Credit  Party also
acknowledges  that  it  will,   independently  and  without  reliance  upon  the
Administrative  Agent or any other Credit Party 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,
any related agreement or any document furnished hereunder or thereunder.

     10.8.   COLLATERAL   AGENT,   MANAGING   AGENTS,   SYNDICATION   AGENT  AND
DOCUMENTATION AGENT.

which it is a party. The Managing Agents,  Syndication  Agent and  Documentation
Agent  shall have no duties or  obligations  under the Loan  Documents  in their
respective  capacities as Managing Agents,  Syndication  Agent and Documentation
Agent.   The  Collateral   Agent,   Managing  Agents,   Syndication   Agent  and
Documentation  Agent shall be entitled to the same protections,  indemnifies and
rights,  and  subject  to the same  standards  with  respect  to their  actions,

11.  MISCELLANEOUS

     11.1. AMENDMENTS AND WAIVERS.

          (a) No failure to exercise and no delay in exercising,  on the part of
any Credit Party, any right,  remedy, power or privilege under any Loan Document
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any right, remedy, power or privilege under any Loan Document preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies,  powers and privileges under the Loan Documents
are cumulative and not exclusive of any rights, remedies,  powers and privileges
provided by law. No waiver of any  provision of any Loan  Document or consent to
any departure by any Loan Party therefrom shall in any event be effective unless
the same shall be  permitted  by this  Section,  and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given.  Without  limiting the generality of the foregoing,  the making of a Loan
shall not be  construed as a waiver of any  Default,  regardless  of whether any
Credit Party may have had notice or knowledge of such Default at the time.

          (b)  Notwithstanding  anything to the  contrary  contained in any Loan
Document,  with the written consent of the Required Lenders,  the Administrative

Credit  Parties)  may,  from  time  to  time,  enter  into  written  amendments,
supplements  or  modifications  thereof  and,  with the consent of the  Required
Lenders,  the  Administrative  Agent on behalf of the other Credit Parties,  may
execute  and  deliver  to any such  parties  a  written  instrument  waiving  or
consenting  to  the  departure  from,  on  such  terms  and  conditions  as  the
Administrative Agent may specify in such instrument,  any of the requirements of
the Loan Documents or any Default and its consequences;  provided, however, that
no such amendment, supplement, modification, waiver or consent shall:

               (i)  increase  the Tranche A  Commitment  of any Tranche A Lender
     without such Lender's consent;

               (ii) unless agreed to by each Credit Party affected thereby,  (A)

     for the payment of any principal of or interest on any Extension of Credit,
     any fees, or any other  obligation  payable under the Loan  Documents,  (C)

     Maturity  Date,  or (D) extend any date for the  reduction of the Aggregate
     Tranche A Commitments set forth in Section 2.3(b);

               (iii) unless agreed to by all of the Tranche A Lenders, Tranche B
     Lenders  and  Tranche C  Lenders:  (A)  increase  the  Aggregate  Tranche A
     Commitments,  (B) change this Section  11.1,  the  definition  of "Minority
     Lenders" or "Required Lenders" or any other provision hereof specifying the
     number or  percentage  of Lenders  required  to waive,  amend or modify any
     rights hereunder or make any determination or grant any consent  hereunder,
     (C) change Section 2.9 in a manner that would alter the pro rata sharing of
     payments required  thereby,  (D) consent to any assignment or delegation by
     any Loan Party of any of its rights or obligations

                                      -86-

     under any Loan  Document,  (E) release any  Subsidiary  Guarantor  from its
     obligations under the Subsidiary Guaranty,  Arch from its obligations under
     Arch Guaranty or the Parent from its obligations  under the Parent Guaranty
     (except as may be expressly  permitted  thereunder  or  hereunder),  or (F)
     release any of the Collateral  from the Liens of the Collateral  Documents,
     except as may be expressly permitted thereunder or hereunder,

     than  66-2/3% of the (A)  Aggregate  Tranche A  Commitments  in the case of
     Tranche  A  Lenders,  (B)  Aggregate  Tranche B  Commitments  (or after the
     Tranche B Conversion Date, the Aggregate Tranche B Exposure) in the case of

     Loans in the case of  Tranche C  Lenders,  no such  amendment,  supplement,
     modification,  waiver or consent shall change the provisions of Section 2.4
     relating to the  allocation of  prepayments  to the Tranche A Loans and the

be  restored  to their  former  position  and  rights  hereunder  and  under the
outstanding  Notes and other Loan  Documents to the extent  provided for in such
waiver,  and any  Default  waived  shall not extend to any  subsequent  or other

notice or knowledge of any Default or  incorrect  representation  or warranty at
the time any credit is extended hereunder.

     11.4. EXPENSES; INDEMNITY.

          (a) The Borrower agrees,  on demand therefor and whether any Extension

including  the  reasonable  fees,  charges  and  disbursements  of  counsel,  in
connection  with  the  development,   preparation,  execution,  syndication  and
administration  of, the Loan Documents  (including any amendment,  supplement or
other  modification  thereto  (whether  or  not  executed  or  effective)),  any
documents  prepared  in  connection   therewith  and  the  consummation  of  the
transactions contemplated thereby and (ii) to pay or reimburse each Credit Party

the fees,  charges and  disbursements  of any  counsel,  incurred by or asserted
against any  Indemnified  Person in connection with or in any way arising out of
any Loan Document, any other Transaction Document or any Transaction,  including
as a result of (i) any breach by the Borrower of the terms of any Loan Document,
the use of proceeds of any  Extension  of Credit or any action or failure to act
on the part of the Borrower,  (ii) the consummation or proposed  consummation of
the  Transactions  or any  other  transactions  contemplated  hereby,  (iii) any
Extension  of Credit or the use of the  proceeds  therefrom,  (iv) any actual or
alleged presence or release of Hazardous Substance on or from any property owned

its Subsidiaries, (v) any action or failure to act on the part of the

                                      -88-
<PAGE>


Borrower or (vi) any actual or prospective claim,  litigation,  investigation or
proceeding relating to any of the foregoing,  whether based on contract, tort or
any other theory and  regardless  of whether any  Indemnified  Person is a party
thereto  (collectively,  the  "INDEMNIFIED  LIABILITIES"),  provided  that  such
indemnity  shall not, as to any Indemnified  Person,  be available to the extent
that such losses, claims, damages, liabilities or related expenses resulted from
the gross negligence or wilful misconduct of such Indemnified Person.

          (c) To the extent that the Borrower  fails to pay any amount  required
to be paid by it to the  Administrative  Agent  or any of its  Affiliates  under
subsections (a) or (b) of this Section,  each Lender severally agrees, on demand
therefor,  to pay to the Administrative  Agent such Lender's Total Percentage of
such amount (determined as of the time that the applicable  unreimbursed expense
or Indemnified Liability is sought).

     11.5. SUCCESSORS AND ASSIGNS

          (a) The Loan Documents  shall be binding upon and inure to the benefit
of each of the parties  thereto,  and their  respective  successors and assigns,
except that no Loan Party may assign or otherwise  transfer any of its rights or
obligations  hereunder  without the prior  written  consent of each Credit Party
(and any such  attempted  assignment  or transfer  without such consent shall be
null and void).

          (b)  Each  Lender  may  assign  all or a  portion  of its  rights  and
obligations  under the Loan Documents to (i) any Subsidiary or Affiliate of such
Lender,  (ii) any other Lender,  or (iii) with the consent of the Borrower,  the
Administrative  Agent and the Letter of Credit Issuer (which  consents shall not
be unreasonably  withheld or delayed and, in the case of the Borrower's consent,
shall not be required  during the  continuance  of an Event of Default),  to any
other Eligible Institution, provided that:

               (A)  except  in the  case  of an  assignment  to a  Lender  or an
     Affiliate of a Lender or an  assignment of the entire  remaining  amount of
     the assigning Lender's rights and obligations under the Loan Documents, the
     amount of the assigning  Lender's  Tranche A Commitment  and Tranche C Loan
     subject  to such  assignment,  when  added to the  amount of the  assigning
     Lender's  Tranche B Commitment  (or, if the Tranche B Commitment  no longer
     exists,  the Tranche B Loans) subject to a simultaneous  assignment made by
     such assigning Lender to the same Eligible  Institution under the Tranche B
     Credit  Agreement  (determined as of the date the Assignment and Acceptance
     Agreement   with   respect  to  such   assignment   is   delivered  to  the
     Administrative Agent) shall not be less than $5,000,000, and

               (B) for each  assignment,  the assignor and such  assignee  shall
     deliver to the  Administrative  Agent  three  copies of an  Assignment  and
     Acceptance Agreement executed by each of them, along with an assignment fee
     in the sum of $3,500 for the  account of the  Administrative  Agent and, if
     the  assignee  is not then a Lender  and is a  Foreign  Credit  Party,  the
     documents required by Section 3.6(c).

Upon  receipt of such  number of  executed  copies of each such  Assignment  and
Acceptance  Agreement together with the assignment fee therefor and the consents
required to such assignment,  if required, the Administrative Agent shall record
the same and execute not less than two copies of such  Assignment and Acceptance
Agreement in the  appropriate  place,  deliver one such copy to the assignor and
one such copy to the assignee,  and deliver one photocopy thereof,  as executed,
to the Borrower. From and after the Assignment

                                      -89-
<PAGE>


Effective Date  specified in, and as defined in, such  Assignment and Acceptance
Agreement,  the assignee  thereunder  shall,  unless already a Lender,  become a
party  hereto and shall,  for all  purposes of the Loan  Documents,  be deemed a
"Lender"  and,  to  the  extent  provided  in  such  Assignment  and  Acceptance
Agreement, the assignor Lender thereunder shall be released from its obligations
under this Agreement and the other Loan Documents.  The Borrower agrees that, if
requested, in connection with each such assignment, it shall at its own cost and
expense execute and deliver to the Administrative Agent or such assignee a Note,
each  payable to the order of such  assignee  and dated the  Second  Restatement
Date.   The   Administrative   Agent   shall  be   entitled  to  rely  upon  the
representations  and warranties  made by the assignee under each  Assignment and
Acceptance Agreement.

          (c) Each  Lender  may grant  participations  in all or any part of its
rights  and  obligations  under  the  Loan  Documents  to one or  more  Eligible
Institutions,  provided that (i) such Lender's  obligations under this Agreement
and the other Loan  Documents  shall  remain  unchanged,  (ii) such Lender shall
remain solely  responsible  to the other parties to this Agreement and the other
Loan Documents for the performance of such  obligations,  (iii) the Borrower and
the Credit  Parties shall  continue to deal solely and directly with such Lender
in  connection  with  such  Lender's  rights  and  obligations  under  the  Loan
Documents,  (iv) the  Borrower  shall  not at any time be  obligated  to pay any
participant in any interest of any Lender hereunder any sum in excess of the sum
which the Borrower would have been obligated to pay to such Lender in respect of
such  interest had such Lender not sold such  participation,  and (v) the voting
rights of any holder of any participation  shall be limited to decisions that in
accordance with Section 11.1 require the consent of all of the Lenders.

          (d) Subject to subsection (e) below, any Lender may at any time assign
all or any portion of its rights under any Loan Document to any Federal  Reserve
Bank.

          (e) Except to the extent of any assignment  pursuant to subsection (b)
above,  no Lender  shall be  relieved of any of its  obligations  under the Loan
Documents as a result of any assignment of or granting of participations in, all
or any part of its rights and obligations under the Loan Documents.

     11.6. COUNTERPARTS; INTEGRATION.

          Each Loan  Document  (other  than the Notes) may be executed by one or
more of the parties  thereto on any number of separate  counterparts  and all of
said counterparts  taken together shall be deemed to constitute one and the same
document.  It shall not be  necessary  in making  proof of any Loan  Document to
produce  or  account  for more  than one  counterpart  signed by the party to be
charged.  Delivery of an executed  counterpart  of a signature  page of any Loan
Document by  facsimile  shall be  effective  as delivery of a manually  executed
counterpart  of such Loan Document.  The Loan Documents and any separate  letter
agreements  between the  Borrower and a Credit Party with respect to fees embody
the entire  agreement  and  understanding  among the Loan Parties and the Credit
Parties  with  respect to the subject  matter  thereof and  supersede  all prior
agreements and understandings among the Loan Parties and the Credit Parties with
respect to the subject matter thereof.

     11.7. SEVERABILITY.

          Every provision of the Loan Documents is intended to be severable, and
if any term or provision thereof shall be invalid,  illegal or unenforceable for
any  reason,  the  validity,   legality  and  enforceability  of  the  remaining
provisions  thereof  shall  not  be  affected  or  impaired  thereby,   and  any
invalidity,  illegality or unenforceability in any jurisdiction shall not affect
the validity,  legality or  enforceability  of any such term or provision in any
other jurisdiction.

     11.8. GOVERNING LAW.

          THE LOAN  DOCUMENTS  AND THE RIGHTS  AND  OBLIGATIONS  OF THE  PARTIES
THEREUNDER  SHALL BE GOVERNED BY, AND  CONSTRUED AND  INTERPRETED  IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK.

     11.9. JURISDICTION; SERVICE OF PROCESS.

          Each  party  to a Loan  Document  hereby  irrevocably  submits  to the
nonexclusive  jurisdiction of any New York State or Federal court sitting in the
City of New York over any suit, action or proceeding  arising out of or relating
to the Loan Documents.  Each party to a Loan Document hereby irrevocably waives,
to the fullest extent permitted or not prohibited by law, any objection which it
may now or hereafter have to the laying of the venue of any such suit, action or
proceeding  brought in such a court and any claim that any such suit,  action or
proceeding  brought in such a court has been brought in an  inconvenient  forum.
Each Loan Party hereby agrees that a final judgment in any such suit,  action or
proceeding  brought in such a court,  after all  appropriate  appeals,  shall be
conclusive  and binding  upon it 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 a Credit Party may otherwise have to bring
any action or proceeding  relating to Loan Documents against the Borrower or its
properties  in the courts of any  jurisdiction.  Each  party to a Loan  Document
hereby  irrevocably  consents to service of process in the manner  provided  for
notices in Section 11.2.  Nothing in this Agreement will affect the right of any
party to a Loan Document to serve process in any other manner permitted by law.

     11.10. WAIVER OF TRIAL BY JURY.

          EACH PARTY HERETO HEREBY WAIVES,  TO THE FULLEST  EXTENT  PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING
DIRECTLY OR  INDIRECTLY  ARISING OUT OF OR  RELATING  TO THIS  AGREEMENT  OR THE
TRANSACTIONS  CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,  TORT OR ANY OTHER
THEORY).  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 BY, AMONG OTHER THINGS,  THE MUTUAL WAIVERS
AND CERTIFICATIONS IN THIS SECTION.

     11.11. SAVINGS CLAUSE.

          This   Agreement  is  intended   solely  as  an   amendment   of,  and
contemporaneous  restatement  of, the terms and  conditions  of the Existing ACE
Credit  Agreement and the Notes delivered  pursuant hereto are intended to amend
and restate the notes issued under the Existing ACE Credit Agreement and neither
this  Agreement or the Notes is intended  and neither  should be construed as in
any way  extinguishing  or terminating  the Existing ACE Credit  Agreement.  The
Existing Borrower Security Agreement and the Existing  Subsidiary  Guaranty,  to
the extent  provided in the Borrower  Pledge  Agreement  (Bank),  the Subsidiary
Guaranty and the Restricted  Subsidiary Security Agreement (Bank) remain in full
force and effect and continue to secure the  obligations  of the Loan Parties as

     11.12. CONFIDENTIALITY.

          Each of the Lenders and the Administrative  Agent agrees (on behalf of
itself  and  each  of  its  affiliates,   directors,   officers,  employees  and
representatives)  to  use  reasonable  precautions  to  keep  confidential,   in
accordance with their customary procedures for handling confidential information
of the same nature, all non-public information supplied by Arch, the Borrower or
any of their  respective  Subsidiaries  pursuant to this Agreement  which (a) is
identified  by such  Person  as  being  confidential  at the  time  the  same is
delivered to such Lender or the  Administrative  Agent,  or (b)  constitutes any
financial  statement,  financial  projections or forecasts,  budget,  compliance
certificate,  audit  report,  management  letter or  accountants'  certification
delivered hereunder (collectively,  the "CONFIDENTIAL  INFORMATION"),  provided,
however,  that nothing  herein shall limit the  disclosure  of any  Confidential
Information (i) to the extent required by statute,  rule, regulation or judicial
process,  (ii) on a confidential  basis, to counsel to any of the Lenders or the
Administrative Agent, (iii) to bank examiners,  auditors or accountants, and any
analogous  counterpart thereof, (iv) to the Administrative Agent or the Lenders,
(v) in connection with any litigation to which any one or more of the Lenders or
the Administrative Agent is a party, provided that if practicable to do so under
the  circumstances,  Arch or the  Borrower,  as the case may be, is given  prior
notice of, and an  opportunity to contest,  the production of such  Confidential
Information  (which such notice and  opportunity  shall be reasonable  under the
circumstances),  (vi) to any assignee or participant (or prospective assignee or
participant) so long as such assignee or participant (or prospective assignee or
participant)   agrees  in   writing  to  keep  such   Confidential   Information
confidential on  substantially  the same basis as set forth in this Section,  or
(vii) to affiliates of the Administrative Agent or each Lender.  Notwithstanding
the provisions of clause (vii) above,  neither the Administrative  Agent nor any
Lender shall disclose any such Confidential Information to any of its respective
affiliates,  directors,  officers,  employees or  representatives  except to the
extent  that it or they have a need to know  such  Confidential  Information  in
connection  with the  structuring  or  administration  of the  Loans or any Loan
Document,  any  assignment or  participation  thereof or  activities  incidental
thereto.

     11.13. RELEASE OF BENBOW ASSETS.

          By  executing  this  Agreement,  each  of the  Credit  Parties  hereby
authorizes  BNY as the  Administrative  Agent under (i) the Existing  Subsidiary
Guaranty  to release  the Liens  granted by  Westlink  thereunder  in the Benbow
Assets, (ii) the Existing Parent Security Agreement to release the Liens granted
by the Parent  thereunder in the Benbow Assets,  and (iii) the Existing Borrower
Security  Agreement  the Liens  granted by ACE in its Stock in  Westlink  II (if
any). Nothing herein shall affect the right of the Credit Parties to

                                      -92-
<PAGE>


require Benbow  Investments to become a Subsidiary  Guarantor and a party to the

Advance (subject to the provisions of the definition of Interest  Period).  Each
such notice shall be  irrevocable  and confirmed  immediately by delivery to the
Administrative  Agent  of a Credit  Request.  Each  ABR  Advance  shall be in an
aggregate  principal  amount  equal  to  $100,000  or such  amount  plus a whole
multiple of $100,000 in excess  thereof,  or, if less,  the unused amount of the
Aggregate  Tranche B  Commitments,  and each  Eurodollar  Advance shall be in an
aggregate  principal  amount  equal  to  $500,000  or such  amount  plus a whole
multiple of $100,000 in excess thereof.  If, with respect to any borrowing,  the
Borrower shall fail to give due notice as provided in this Section, the Borrower
shall be deemed to have selected an ABR Advance for such borrowing.

          (b) Upon receipt of such notice of borrowing  from the  Borrower,  the
Administrative  Agent shall promptly notify each Lender which is a member of the
Class from which a Loan has been requested of such notice of borrowing.  Subject
to its receipt of the notice referred to in the preceding sentence, each Tranche
B Lender will make the amount of its Tranche B Percentage of each such borrowing
of Tranche B Loans available to the Administrative  Agent for the account of the
Borrower at the Payment Office not later than 2:30 p.m., on the relevant  Credit
Extension Date requested by the Borrower,  in funds immediately available to the
Administrative  Agent at such  office.  The  amounts  so made  available  to the
Administrative  Agent on such Credit  Extension  Date will then,  subject to the
satisfaction  of the terms and conditions of this Agreement as determined by the

                                      -30-
<PAGE>

Administrative  Agent,  be made  available  on such date to the  Borrower by the
Administrative  Agent at the  Payment  Office by  crediting  the  account of the
Borrower on the books of such office with the aggregate of said amounts received
by the Administrative Agent. Unless the Administrative Agent shall have received
prior  notice  from a Lender  (by  telephone  or  otherwise,  such  notice to be
confirmed by telecopy or other  writing) that it will not make  available to the
Administrative  Agent its Tranche B  Percentage  of any Loans  requested  by the
Borrower and with respect to which it has a Commitment, the Administrative Agent
may assume that such Lender has made such share available to the  Administrative
Agent on the requested  Credit  Extension Date in accordance  with this Section,
provided that such Lender  received  notice of the proposed  borrowing  from the
Administrative  Agent, and the  Administrative  Agent may, in reliance upon such
assumption,  make  available  to the  Borrower on such Credit  Extension  Date a
corresponding  amount.  If and to the extent such Lender  shall not have so made
such share available to the  Administrative  Agent, such Lender and the Borrower
severally  agree to pay to the  Administrative  Agent  forthwith  on demand such
corresponding amount (to the extent not previously paid by the other),  together
with interest  thereon for each day from the date such amount is made  available
to the Borrower until the date such amount is paid to the Administrative  Agent,
at a rate per  annum  equal  to,  in the case of the  Borrower,  the  applicable
interest  rate set forth in Section 3.1,  and, in the case of such  Lender,  the
Federal Funds Rate in effect on such date (as  determined by the  Administrative
Agent). Such payment by the Borrower, however, shall be without prejudice to its
rights against such Lender. If such Lender shall pay to the Administrative Agent
such corresponding amount, such amount so paid (excluding, however, any interest
payable on such amount)  shall  constitute  such  Lender's  Loan as part of such
Loans for  purposes of this  Agreement,  which Loan shall be deemed to have been
made by such Lender on the Credit Extension Date applicable to such Loans.

          (c) If a Lender makes a new Loan to the Borrower on a Credit Extension
Date on which the Borrower is to repay a Loan of such Lender of the same type or
make a scheduled amortization payment on a Loan of such Lender of the same type,
such Lender shall apply the proceeds of such new Loan to make such  repayment or
scheduled  amortization payment, and only the excess of the proceeds of such new
Loan over the Loan being repaid or  scheduled  amortization  payment  being made
need be made available to the Administrative Agent.

          (d) Notices of borrowing given by telephone shall be deemed given when
made by telephone and the Administrative  Agent and the Lenders may rely thereon
whether or not such notice is confirmed by the delivery of a Credit Request.

     2.3. TERMINATION OR REDUCTION OF THE AGGREGATE TRANCHE B COMMITMENTS.

          (a) VOLUNTARY  REDUCTIONS.  The Borrower shall have the right, upon at
least  three  Business  Days'  prior  written  notice  from the  Borrower to the
Administrative  Agent,  at  any  time  to  terminate  the  Aggregate  Tranche  B
Commitments or from time to time to reduce  permanently the unused amount of the
Aggregate  Tranche  B  Commitments  to an  amount  not less  than the  aggregate
principal  amount of  outstanding  Tranche B Loans (after  giving  effect to any
contemporaneous  payment or prepayment of Tranche B Loans).  Any such  reduction
shall be in the amount of  $1,000,000  or such amount  plus a whole  multiple of
$100,000.

                                      -31-
<PAGE>

          (b) MANDATORY TERMINATION. Notwithstanding anything to the contrary in
any Loan Document,  the Aggregate  Tranche B Commitments  shall terminate on the
Tranche B Conversion Date.

          (c) OTHER MANDATORY  REDUCTIONS.  The Aggregate  Tranche B Commitments
shall be permanently reduced at the times and in the amounts required by Section
2.4.

          (d) IN GENERAL.  Each reduction of the Aggregate Tranche B Commitments
shall be made by reducing each Lender's Tranche B Commitments by an amount equal
to such Lender's  Tranche B Percentage of such  reduction.  Simultaneously  with
each reduction of the Aggregate  Tranche B  Commitments,  the Borrower shall pay
the  Tranche B  Commitment  Fee  accrued  on the  amount by which the  Aggregate
Tranche B Commitments has been reduced.

     2.4. APPLICATION OF PROCEEDS.

          On or before  each date set forth  below,  (i) prior to the  Tranche B
Conversion  Date,  the  Aggregate  Tranche B  Commitments  shall be  permanently
reduced,  and (ii) on or after the Tranche B Conversion Date, the Borrower shall
prepay the  aggregate  unpaid  principal  amount of the  Tranche B Loans,  by an
amount equal to the Aggregate Tranche B Percentage of the amount set forth below
and applicable to such date:

               (a)  on  the  last  day  of  the  Reinvestment  Period  for  each
     Disposition  by an amount equal to 100% of the  Adjusted Net Cash  Proceeds
     with respect to such Disposition;

               (b) for each  fiscal  year prior to the fiscal  year in which the
     Existing  Arch Senior Note  Termination  Date occurs,  commencing  with the
     fiscal year ended  December 31, 1999,  and  effective on March 31st of each
     immediately  succeeding fiscal year, by an amount equal to (i) if the Total
     Leverage  Ratio at the end of such fiscal year is greater  than  4.00:1.00,
     the lesser of (A) 80% of Excess  Cash Flow (the  "MAXIMUM  EXCESS CASH FLOW
     AMOUNT")  and (B) an  amount  equal  to the sum of (1) the  portion  of the
     Maximum  Excess Cash Flow Amount which will reduce the Total Leverage Ratio
     to  4.00:1:00  at the end of such fiscal  year,  PLUS (2) 50% of the amount
     equal to Excess Cash Flow MINUS such portion  referred to in clause  (B)(1)
     above,  or (ii) if the Total  Leverage Ratio at the end of such fiscal year
     is less than or equal to 4.00:1.00, 50% of Excess Cash Flow;

               (c) in an amount equal to all  Applicable  Proceeds (i) in excess
     of amounts used to replace or repair any  properties  or (ii) which are not
     used or  designated to replace or repair  properties  within one year after
     receipt  thereof,  provided that the Borrower or the applicable  Subsidiary
     Guarantor  shall have  commenced the  restoration  or  replacement  process
     (including  the making of  appropriate  filings and requests for  approval)
     within  45 days  after  such  casualty  or after  the  receipt  of any such
     condemnation  proceeds, as the case may be, and diligently pursues the same
     through completion.

                                                   unpaid  principal  amount  of
                                                   the Tranche B Loans  together
                                                   with all  accrued  and unpaid
                                                   interest thereon.

          (b) VOLUNTARY PREPAYMENTS. The Borrower may, at its option, prepay the
Loans,  in whole or in part, at any time and from time to time, by notifying the
Administrative  Agent in writing at least one Business Day prior to the proposed
prepayment  date in the case of ABR Advances,  and at least three  Business Days
prior to the proposed  prepayment  date in the case of Eurodollar  Advances,  in
each case  specifying  (i)  whether  the Loans to be  prepaid  consist of an ABR
Advance,  a Eurodollar Advance or a combination  thereof,  (ii) the amount to be
prepaid and (iii) the date of prepayment.  Such notice shall be irrevocable  and
the payment amount specified in such notice shall be due and payable on the date
specified,  together  with  accrued  interest to the date of such payment on the
amount  prepaid.  Upon receipt of such notice,  the  Administrative  Agent shall
promptly notify each Lender in respect thereof. Partial prepayments of the Loans
shall be in an aggregate  principal  amount of  $1,000,000 or such amount plus a
whole multiple of $100,000 or, if less, the outstanding principal balance of the
Loans.  After giving effect to any partial prepayment with respect to Eurodollar
Advances  which were made (whether as the result of a borrowing or a conversion)
on the same  date  and  which  had the same  Interest  Period,  the  outstanding
principal  amount of such  Eurodollar  Advances made (whether as the result of a
borrowing  or a  conversion)  shall not be less than  (subject  to Section  3.3)
$500,000.

<PAGE>

          (c) MANDATORY  PREPAYMENTS  RELATING TO REDUCTIONS OR  TERMINATION  OF
COMMITMENTS.  At any time prior to the Tranche B Conversion Date, simultaneously
with each reduction or termination of the Aggregate  Tranche B Commitments,  the
Borrower  shall  prepay the Tranche B Loans by the amount,  if any, by which the
Aggregate  Tranche B  Exposure  exceeds  the amount of the  Aggregate  Tranche B
Commitments as so reduced or terminated.

          (d) OTHER MANDATORY PREPAYMENTS.  The Tranche B Loans shall be prepaid
at the times and in the amounts required by Section 2.4.

          (e) APPLICATION OF PREPAYMENTS. Each prepayment of the Tranche B Loans
pursuant to Sections  2.4(a),  (b) and (c) and Section  2.5(b)  shall be applied
against the remaining  installments of principal required to be paid pursuant to
Section 2.5(a) pro rata against such installments.

          (f) IN GENERAL.  Unless  otherwise  specified  by the  Borrower,  each
prepayment  of  the  Loans  shall  first  be  applied  to ABR  Advances.  If any
prepayment is made in respect of any  Eurodollar  Advance,  in whole or in part,
prior to the last day of the applicable  Interest Period, the Borrower agrees to
indemnify the Lenders in accordance with Section 3.4.

     2.6. [INTENTIONALLY OMITTED.]

     2.7. USE OF PROCEEDS.

          The  proceeds  of the  Extensions  of  Credit  shall  be used  solely,
directly or indirectly,  (i) for general corporate  purposes of the Borrower and
its  Subsidiaries,  including  Capital  Expenditures  and working  capital,  not
inconsistent  with the provisions  hereof,  (ii) to finance  Acquisitions to the
extent permitted by Section 8.6, (iii) to make Restricted Payments to the extent
permitted by Section 8.5, and (iv) to pay the reasonable  out-of-pocket fees and
expenses   incurred  by  the  Borrower  in  connection  with  the   transactions
contemplated  by the  Transaction  Documents.  Notwithstanding  anything  to the
contrary contained in any Loan Document, the Borrower agrees that no part of the
proceeds of any Extensions of Credit will be used, directly or indirectly, for a
purpose which violates any law,  including the provisions of Regulations T, U or
X.

     2.8. NOTES; REGISTRATION.

          (a) IN GENERAL.  The Loans made by each Lender shall be evidenced by a
Note.

          (b) REGISTERED NOTES.

               (i) Any Foreign  Credit  Party  which is not a "bank"  within the
     meaning  of  Section  881(c)(3)(A)  of the  Code  and  which  could  become
     completely  exempt from  withholding of U.S. Taxes in respect of payment of
     any  obligations  due it under the Loan  Documents  relating  to any of its
     Loans,  if such Loans were in registered  form for U.S.  Federal income tax
     purposes,  may request the Borrower (through the Administrative Agent), and
     the Borrower  agrees  thereupon,  (A) in the case of a Foreign Credit Party
     listed on the  signature  pages  hereof,  to exchange  such Foreign  Credit
     Party's Note for a promissory  note  registered as provided in clause (iii)
     below (each, a "REGISTERED NOTE") and (B) in the case of each other Foreign

                                      -34-
<PAGE>

     Credit Party, to issue to such Foreign Credit Party its Note in the form of
     a Registered  Note. A Registered  Note may not be exchanged for a Note that
     is not in registered form.

               (ii) Each  Foreign  Credit  Party  holding a  Registered  Note (a
     "REGISTERED  NOTEHOLDER")  and,  if such  Foreign  Credit  Party is not the
     beneficial  owner  thereof,  such  beneficial  owner,  shall deliver to the
     Borrower and the Administrative  Agent prior to or at the time such Foreign
     Credit Party becomes a Registered  Noteholder,  a Form W-8  (Certificate of
     Foreign  Status of the  Department of Treasury of the United States) or the
     successor  form thereto and any related forms  (including,  if  applicable,
     Form  W-8C) and  related  forms as may from time to time be  adopted by the
     relevant  taxing  authorities  of the United  States  which are required to
     allow  payments of portfolio  interest  (within the meaning of Code Section
     871(b) to be made free of United States  withholding  tax. Each  Registered
     Noteholder shall also deliver to the Borrower and the Administrative  Agent
     an annual certificate stating that such Registered Noteholder or beneficial
     owner,  as the case may be, is not a "bank"  within the  meaning of section
     881(c)(3)(A)  of the  Code  and  is  not  otherwise  described  in  Section
     881(c)(3) of the Code. Each Registered  Noteholder or beneficial  owner, as
     the case may be, shall promptly notify the Borrower and the  Administrative
     Agent if at any time such Registered Noteholder or beneficial owner, as the
     case may be,  determines that it is no longer in a position to provide such
     certificate  (or any other form of  certification  adopted by the  relevant
     taxing authorities of the United States for such purposes).

               (iii) The Borrower shall maintain,  or cause to be maintained,  a
     register (the "REGISTER") which shall be kept by the  Administrative  Agent
     on behalf of the Borrower at no extra charge to the Borrower at the Payment
     Office  which shall set forth (A) the names and  addresses  of each Lender,
     including each registered  owner of Loans  evidenced by a Registered  Note,
     (B) the Class or Classes of the Loans of such Lender, and (C) the principal
     amount of its Tranche B Loans outstanding from time to time. The entries in
     the  Register  shall be binding and  conclusive  for all  purposes,  absent
     manifest  error,  and the Borrower,  and each Credit Party shall treat each
     Person  whose name is recorded in the Register as a Lender for all purposes
     under this Agreement.

               (iv)  In  addition  to  the   requirements  of  Section  11.5,  a
     Registered  Note (and the  Loans  evidenced  thereby)  may be  assigned  or
     otherwise  transferred  in whole or in part  only by  registration  of such
     assignment  or transfer of such  Registered  Note (and the Loans  evidenced
     thereby) on the  REGISTER  (and each  Registered  Note shall  expressly  so
     provide).  Any  assignment or transfer of all or part of such Loans and the
     Registered  Note  evidencing  the same shall be  registered on the Register
     only upon  compliance  with the  requirements of Section 11.5 and surrender
     for   registration  of  assignment  or  transfer  of  the  Registered  Note
     evidencing  such  Loans,  duly  endorsed  by (or  accompanied  by a written
     instrument  of  assignment or transfer  fully  executed by) the  Registered
     Noteholder  thereof,  and thereupon one or more new Registered Notes in the
     same  aggregate   principal  amount  shall  be  issued  to  the  designated
     assignee(s)  or   transferee(s).   Prior  to  the  due   presentation   for
     registration  of transfer of any  Registered  Note,  the  Borrower  and the
     Administrative  Agent  shall  treat the Person in whose name such Loans and
     the Registered  Note evidencing the same is registered as the owner thereof
     for the  purpose  of  receiving  all  payments  thereon  and for all  other
     purposes, notwithstanding any notice to the contrary.

     2.9. PAYMENTS; PRO RATA TREATMENT AND SHARING OF SET-OFFS.

          (a) PAYMENTS  GENERALLY.  (i) Except as provided below,  all payments,
including prepayments,  of principal and interest on the Loans, of the Tranche B
Commitment  Fee and of all other  amounts to be paid by the  Borrower  under the
Loan  Documents  (the Tranche B Commitment  Fee together  with all of such other
fees, being sometimes hereinafter  collectively referred to as the "FEES") shall
be made to the Administrative Agent, prior to 1:00 p.m. on the date such payment
is due, for the account of the applicable  Credit Parties at the Payment Office,
in  Dollars  and  in  immediately  available  funds,  without  set-off,  offset,
recoupment or counterclaim. The failure of the Borrower to make any such payment
by such time shall not constitute a Default,  provided that such payment is made
on such due date,  but any such  payment  made after 1:00 p.m.  on such due date
shall be deemed to have been made on the next  Business  Day for the  purpose of
calculating  interest  on  amounts  outstanding  on the Loans.  As  between  the
Borrower   and  each  Credit   Party,   any  payment  by  the  Borrower  to  the
Administrative  Agent for the account of such Credit Party shall be deemed to be
payment by the Borrower to such Credit Party. Notwithstanding the foregoing, all
payments  pursuant to Sections  3.4, 3.5, 3.6 and 11.4 shall be paid directly to
the Credit Party entitled thereto. If any payment under the Loan Documents shall
be due and payable on a day which is not a Business  Day,  the due date  thereof
(except as  otherwise  provided  with  respect  to  Interest  Periods)  shall be
extended  to the next  Business  Day and  (except  with  respect to  payments in
respect of the Fees) interest shall be payable at the applicable  rate specified
herein during such extension,  provided, however, that if such next Business Day
would be after the Tranche B Maturity Date, such payment shall instead be due on
the immediately preceding Business Day.

               (ii)  If at any  time  insufficient  funds  are  received  by and
available  to the  Administrative  Agent to pay fully all amounts of  principal,
interest  and Fees then due  hereunder,  such funds  shall be applied (A) first,
towards payment of interest and Fees then due under the Loan Documents,  ratably
among the parties  entitled  thereto in accordance  with the amounts of interest
and Fees then due to such parties, and (B) second,  towards payment of principal
then due under the Loan Documents, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties.

          (b)  SET-OFF.  In  addition  to any rights and  remedies of the Credit
Parties  provided by law, upon and after the acceleration of all the obligations
of the Borrower under the Loan Documents to which it is a party,  or at any time
upon the  occurrence  and during the  continuance  of an Event of Default  under
Sections  9.1(a) or (b),  each Credit Party shall have the right,  without prior
notice to any Loan Party,  any such notice being  expressly  waived by each Loan
Party to the extent not  prohibited  by  applicable  law,  to set-off  and apply
against any  indebtedness,  whether matured or unmatured,  of such Loan Party to
such Credit  Party any amount  owing from such Credit  Party to such Loan Party,
at, or at any time after, the happening of any of the above-mentioned events. To
the extent not prohibited by applicable  law, the aforesaid right of set-off may
be exercised by any Credit Party  against such Loan Party or against any trustee
in  bankruptcy,  custodian,  debtor in  possession,  assignee for the benefit of
creditors,  receiver, or execution, judgment or attachment creditor of such Loan
Party,  or against anyone else claiming  through or against such Loan Party,  or
such trustee in bankruptcy,  custodian,  debtor in possession,  assignee for the
benefit of creditors,  receiver, or execution,  judgment or attachment creditor,
notwithstanding  the  fact  that  such  right of  set-off  shall  not have  been
exercised  by such  Credit  Party prior to the making,  filing or  issuance,  or

                                      -36-

service  upon  such  Credit  Party  of,  or of  notice  of,  any such  petition,
assignment  for the benefit of creditors,  appointment  or  application  for the
appointment of a receiver, or issuance of execution, subpoena, order or warrant.
Each Credit Party agrees promptly to notify the Borrower and the  Administrative
Agent after any such set-off and application made by such Credit Party, provided
that the  failure to give such  notice  shall not affect  the  validity  of such
set-off and application.

          (c)  ADJUSTMENTS.  If any Lender  shall  obtain any  payment  (whether
voluntary,  involuntary,  through  the  exercise  of any  right of  set-off,  or
otherwise) in respect of the principal of or interest on its Loans, resulting in
such Lender receiving payment of a greater proportion of the aggregate principal
amount of, or accrued  interest on, such Loans than the  proportion  received by
any other  Lender,  then the Lender  receiving  such  greater  proportion  shall
promptly  purchase,  at face value for cash,  participations in the Loans to the
extent  necessary  so that the  benefit of such  payment  shall be shared by the
Lenders  ratably in  accordance  with the  aggregate  amount of principal of and
accrued interest on their respective Loans,  provided,  however, that (i) if all
or any portion of such payment is  thereafter  recovered or repaid in good faith
settlement of a pending or threatened avoidance claim, such participations shall
be rescinded and the purchase price returned, in each case to the extent of such
recovery or settlement  payment,  and (ii) the provisions of this Section 2.9(c)
shall not be construed to apply to any payment made by the Borrower  pursuant to
and in  accordance  with the  express  terms of this  Agreement  or any  payment
obtained  by a  Lender  as  consideration  for  the  assignment  of or sale of a
participation in any of its Loans to any assignee or participant,  other than to
the Borrower or any Subsidiary or Affiliate  thereof (as to which the provisions
of this Section  2.9(c) shall apply).  The Borrower  agrees that any Lender that
purchased a  participation  pursuant to this subsection may exercise such rights
to payment  (including the right of set-off) with respect to such  participation
as fully as such Lender were the direct  creditor of the  Borrower in the amount
of such participation.

3. INTEREST, FEES, YIELD PROTECTIONS, ETC.

     3.1. INTEREST RATE AND PAYMENT DATES.

          (a) PRIOR TO MATURITY.  Prior to maturity,  the outstanding  principal
balance of the Loans shall bear interest on the unpaid  principal amount thereof
at the applicable interest rate or rates per annum set forth below:

               Advances                                   Rate
               --------                                   ----
        Each ABR Advance                    Alternate   Base  Rate  plus  the   
                                            Applicable Margin applicable to ABR 
                                            Advances.

        Each Eurodollar Advance             Eurodollar Rate for the applicable
                                            Interest Period plus the  Applicable
                                            Margin  applicable  to  Eurodollar 
                                            Advances.

          (b) EXTENT OF DEFAULT;  LATE CHARGES.  Notwithstanding  the foregoing,
after the  occurrence  and during the  continuance  of an Event of Default,  the
outstanding  principal  balance of all Loans  shall bear  interest  at a rate of
interest  per  annum  equal  to 2% above  the  rate  which  would  otherwise  be
applicable pursuant to Section 3.1(a). If any interest,  Commitment Fee or other
amount (other than  principal of the Loans)  payable under the Loan Documents is
not paid when due (whether at the stated  maturity  thereof,  by acceleration or

                                      -37-
<PAGE>

otherwise),  such overdue  amount shall,  to the extent  permitted by applicable
law, bear interest at a rate per annum equal to the Alternate Base Rate plus the
Applicable  Margin plus 2%, in each case from the date of such nonpayment  until
paid in full  (before as well as after  judgment).  All such  interest  shall be
payable on demand.

          (c) IN GENERAL.  Interest on (i) ABR  Advances to the extent  based on
the BNY Rate shall be  calculated  on the basis of a 365 or 366-day year (as the
case may be) and (ii) ABR Advances to the extent based on the Federal Funds Rate
and  Eurodollar  Advances shall be calculated on the basis of a 360-day year, in
each case for the actual  number of days  elapsed,  including  the first day but
excluding the last. Except as otherwise provided in Section 3.1(b),  interest on
each Loan shall be payable in arrears on each Interest  Payment Date  applicable
thereto and upon payment (including  prepayment) in full thereof.  Any change in
the interest rate on a Loan  resulting  from a change in the Alternate Base Rate
shall  become  effective  as of the opening of business on the day on which such
change in the Alternate  Base Rate shall become  effective.  The  Administrative
Agent shall,  as soon as  practicable  following  request  therefor,  notify the
Borrower  and the  Lenders  of the  effective  date and the  amount of each such
change in the Alternate Base Rate, but any failure to so notify shall not in any
manner affect the obligation of the Borrower to pay interest on the Loans in the
amounts and on the dates required. Each determination of the Alternate Base Rate
or a Eurodollar  Rate by the  Administrative  Agent  pursuant to this  Agreement
shall be conclusive and binding on the Borrower and the Lenders absent  manifest
error.  At no time shall the interest  rate payable on the Loans,  together with
the Commitment  Fees and all other fees and other amounts payable under the Loan
Documents,  to the extent the same are construed to constitute interest,  exceed
the  Highest  Lawful  Rate.  If  interest  payable to a Lender on any date would
exceed the maximum amount  permitted by the Highest  Lawful Rate,  such interest
payment shall  automatically be reduced to such maximum  permitted  amount,  and
interest for any subsequent  period,  to the extent less than the maximum amount
permitted for such period by the Highest Lawful Rate,  shall be increased by the
unpaid amount of such reduction.  Any interest  actually received for any period
in excess of such  maximum  allowable  amount for such period shall be deemed to
have been applied as a prepayment of the Loans. The Borrower  acknowledges  that
to the extent interest payable on the ABR Advances is based on the BNY Rate, the
BNY Rate is only one of the bases for  computing  interest  on loans made by the
Lenders, and by basing interest payable on the ABR Advances on the BNY Rate, the
Lenders  have not  committed  to  charge,  and the  Borrower  has not in any way
bargained for, interest based on a lower or the lowest rate at which the Lenders
may now or in the future make loans to other borrowers.

     3.2. FEES.

          (a)  TRANCHE  B  COMMITMENT  FEE.  The  Borrower  agrees to pay to the
Administrative  Agent,  for the account of the  Tranche B Lenders in  accordance
with each such Lender's  Tranche B Percentage,  a fee (the "TRANCHE B COMMITMENT
FEE")  during  the  Tranche B  Commitment  Period  equal to the  Commitment  Fee
Percentage  per annum of the  average  daily  unused  portion  of the  Aggregate
Tranche B Commitments.  The Tranche B Commitment Fee shall be payable  quarterly
in arrears on the last day of each March,  June,  September  and December and on
the date of the  expiration or other  termination  of the Tranche B Commitments.
The Commitment Fee shall be calculated on the basis of a 365 or 366-day year for
the actual number of days elapsed.

                                      -38-
<PAGE>

          (b) AGENTS' FEES. The Borrower agrees to pay to the Agents,  for their
own  respective  accounts,  such other fees as have been agreed to in writing by
the Borrower and/or any of the Agents.

     3.3. CONVERSIONS AND CONTINUATIONS.

          (a) The Borrower may elect from time to time to convert its Eurodollar
Advances  to ABR  Advances  by  giving  the  Administrative  Agent at least  one
Business  Day's prior  irrevocable  notice of such  election  (confirmed  by the
delivery of a Notice of Conversion/Continuation), specifying the amount to be so
converted  and the Interest  Period  relating to such  Eurodollar  Advances.  In
addition,  the  Borrower  may  elect  from time to time to (i)  convert  its ABR
Advances to  Eurodollar  Advances  and to continue  its  Eurodollar  Advances by
selecting  a  new  Interest  Period  therefor,   in  each  case  by  giving  the
Administrative  Agent at least three Business Days' prior irrevocable  notice of
such    election    (confirmed    by   the    delivery    of   a    Notice    of
Conversion/Continuation),  in the case of a  conversion  to or  continuation  of
Eurodollar  Advances,  specifying the amount to be so converted and the Interest
Period  relating  thereto,  provided that any such conversion of ABR Advances to
Eurodollar Advances shall only be made on a Business Day and any such conversion
or continuation of Eurodollar Advances shall only be made on the last day of the
Interest Period applicable to the Eurodollar  Advances which are to be converted
to ABR Advances or  continued as new  Eurodollar  Advances.  The  Administrative
Agent shall promptly provide the applicable Class of Lenders with a copy of each
such Notice of Conversion/Continuation. ABR Advances and Eurodollar Advances may
be converted or continued pursuant to this Section in whole or in part, provided
that  conversions  of ABR Advances to Eurodollar  Advances or  continuations  of
Eurodollar  Advances,  shall be in an aggregate  principal amount of $500,000 or
such  amount  plus a  whole  multiple  of  $100,000.  If,  with  respect  to any
conversion of a Loan from one interest rate basis to another, the Borrower shall
fail to give  due  notice  as  provided  in this  Section,  such  Loan  shall be
automatically  converted to an ABR Advance upon the  expiration  of the Interest
Period with respect thereto.

          (b) Notwithstanding  anything in this Section to the contrary,  no ABR
Advance may be converted to a Eurodollar Advance,  and no Eurodollar Advance may
be continued,  if the Borrower or the Administrative  Agent has knowledge that a
Default or Event of Default has  occurred  and is  continuing  either (i) at the
time the  Borrower  shall  notify the  Administrative  Agent of its  election to
convert or continue or (ii) on the  requested  Conversion/Continuation  Date. In
such event, such ABR Advance shall be automatically  continued as an ABR Advance
or such Eurodollar Advance shall be automatically converted to an ABR Advance on
the last day of the Interest Period applicable to such Eurodollar Advance. If an
Event of Default shall have occurred and be continuing, the Administrative Agent
shall, at the request of the Required Lenders, notify the Borrower (by telephone
or otherwise)  that all, or such lesser amount as the  Administrative  Agent and
the Required Lenders shall  designate,  of the outstanding  Eurodollar  Advances
shall be automatically converted to ABR Advances, in which event such Eurodollar
Advances  shall be  automatically  converted  to ABR  Advances  on the date such
notice is given.  In the event that  Eurodollar  Advances  are  converted to ABR
Advances  at the  request of the  Required  Lenders  pursuant  to the  preceding
sentence,  no Lender shall be entitled to an indemnity  described in Section 3.4
with respect to the Eurodollar Advances so converted.

          (c) Each conversion or  continuation  shall be effected by each member
of the  applicable  Class of Lenders by  applying  the  proceeds  of its new ABR

                                      -39
<PAGE>

Advance or Eurodollar  Advance,  as the case may be, to its Advances (or portion
thereof) being converted or continued (it being  understood that such conversion
or  continuation  shall not constitute a borrowing for purposes of Sections 4, 5
or 6).  Accrued  interest on the Advance (or portion  thereof)  being  converted
shall be paid by the Borrower at the time of conversion.

          (d) Without in any way  limiting  the  obligation  of the  Borrower to
confirm in writing any telephonic  notice of a conversion or continuation  given
to the Administrative  Agent, the Administrative Agent may act without liability
upon the basis of telephonic notice of such conversion or continuation  believed
by the  Administrative  Agent in good faith to be from an authorized  officer of
the Borrower  prior to receipt of written  confirmation.  In each such case, the
Borrower  waives the right to dispute the  Administrative  Agent's record of the
terms of such telephone notice of such conversion or continuation.

          (e) Except as provided in the last sentence of  subsection  (b) above,
if any  prepayment  is made under this Section  with  respect to any  Eurodollar
Advances,  in whole or in part, prior to the last day of the applicable Interest
Period,  the Borrower agrees to indemnify the Lenders in accordance with Section
3.4.

     3.4. FUNDING LOSS

          (a) Notwithstanding  anything contained herein to the contrary, if the
Borrower shall fail to borrow or convert or continue on a Credit  Extension Date
or Conversion/Continuation Date after the Borrower shall have given notice to do
so in which it shall have  requested a  Eurodollar  Advance  pursuant to Section
2.2(a) or 3.3 or if a  Eurodollar  Advance  shall be  terminated  for any reason
(subject to the penultimate  sentence of Section 3.3(b)),  prior to the last day
of the Interest Period applicable  thereto, or if, while a Eurodollar Advance is
outstanding,  any repayment or prepayment of such Eurodollar  Advance is made or
deemed  made for any  reason  (including,  without  limitation,  as a result  of
acceleration  or  illegality)  on a date  which  is prior to the last day of the
Interest Period applicable thereto, the Borrower agrees to indemnify each Lender
against,  and to pay directly to such Lender within ten days after such Lender's
demand therefor, any loss or expense suffered by such Lender as a result of such
failure to borrow,  termination or repayment,  including without limitation,  an
amount, if greater than zero, equal to:

                             A  x   (B-C) x  D
                                             360

where:

"A" equals such Lender's pro rata share of the Affected Principal Amount;

"B" equals the  Eurodollar  Rate  (expressed  as a decimal)  applicable  to such
Advance;

"C" equals the applicable  Eurodollar Rate (expressed as a decimal) in effect on
or about the first day of the applicable Remaining Interest Period, based on the
applicable rates offered or bid on or about such date, for deposits in an amount
equal  approximately  to such Lender's pro rata share of the Affected  Principal
Amount with an Interest Period equal  approximately to the applicable  Remaining
Interest Period, as determined by the Administrative Agent;

                                      -40-
<PAGE>

"D" equals the number of days from and including the first day of the applicable
Remaining  Interest  Period  to but  excluding  the last  day of such  Remaining
Interest Period;

and any other  out-of-pocket loss or expense (including any internal  processing
charge  customarily   charged  by  such  Lender)  suffered  by  such  Lender  in
liquidating  or employing  deposits  acquired to fund or maintain the funding of
the Affected  Principal  Amount,  or  redeploying  funds  prepaid or repaid,  in
amounts  which  correspond  to such  Lender's  pro rata  share of such  proposed
borrowing,  conversion,  terminated Eurodollar Advance, prepayment or repayment.
Each  determination  by the  Administrative  Agent or a Lender  pursuant to this
Section shall be conclusive and binding on the Borrower  absent  manifest error.
Each Lender has indicated  that, if the Borrower  elects to borrow or convert to
or continue  Eurodollar  Advances,  such Lender may wish to purchase one or more
deposits in order to fund or maintain  its  funding of its  Eurodollar  Advances
during the Interest Period in question;  it being understood that the provisions
of this Agreement  relating to such funding are included only for the purpose of
determining the rate of interest to be paid on such Eurodollar  Advances and for
purposes of determining amounts owing under Sections 3.5(a) and 3.6. Each Lender
shall be  entitled to fund and  maintain  its funding of all or any part of each
Eurodollar  Advance  made  by it in  any  manner  it  sees  fit,  but  all  such
determinations  shall  be  made  as if  such  Lender  had  actually  funded  and
maintained its funding of such Eurodollar Advance during the applicable Interest
Period  through the purchase of deposits in an amount  equal to such  Eurodollar
Advance and having a maturity corresponding to such Interest Period.

     3.5. INCREASED COSTS; ILLEGALITY, ETC.

          (a) INCREASED COSTS. If any Change in Law shall impose, modify or make
applicable any reserve, special deposit, compulsory loan, assessment,  increased
cost or similar  requirement against assets held by, or deposits of, or advances
or loans by, or other credit extended by, or any other  acquisition of funds by,
any office of any Credit Party in respect of its  Eurodollar  Advances  which is
not otherwise  included in the determination of a Eurodollar Rate and the result
thereof  is to  increase  the  cost to any  Credit  Party of  making,  renewing,
converting or maintaining its Eurodollar Advances or its commitment to make such
Eurodollar Advances, or to reduce any amount receivable under the Loan Documents
in respect of its  Eurodollar  Advances,  then,  in any such case,  the Borrower
shall  pay such  Credit  Party  such  additional  amounts  as is  sufficient  to
compensate  such Credit  Party for such  additional  cost or  reduction  in such
amount  receivable which such Credit Party deems to be material as determined by
such Credit Party.

          (b) CAPITAL  ADEQUACY.  If any Credit Party determines that any Change
in Law relating to capital requirements has or would have the effect of reducing
the rate of return on such  Credit  Party's  capital  or on the  capital of such
Credit Party's holding  company,  if any, on the Extensions of Credit to a level
below that which such Credit Party (or its holding  company) would have achieved
or would  thereafter be able to achieve but for such Change in Law (after taking
into account such Credit Party's (or such holding company's)  policies regarding
capital adequacy),  the Borrower shall pay to such Credit Party (or such holding
company) such additional  amount or amounts as will compensate such Credit Party
(or such holding company) for such reduction.

          (c) ILLEGALITY.  Notwithstanding  any other provision  hereof,  if any
Lender shall reasonably determine that any law, regulation, treaty or directive,
or any change therein or in the  interpretation  or application  thereof,  shall
make it unlawful for such Lender to make or maintain any  Eurodollar  Advance as

                                      -41-
<PAGE>

contemplated by this  Agreement,  such Lender shall promptly notify the Borrower
and the Administrative  Agent thereof,  and (i) the commitment of such Lender to
make such  Eurodollar  Advances or convert ABR Advances to  Eurodollar  Advances
shall  forthwith be  suspended,  (ii) such Lender shall fund its portion of each
requested  Eurodollar  Advance as an ABR Advance and (iii) such  Lender's  Loans
then  outstanding  as such  Eurodollar  Advances,  if any,  shall  be  converted
automatically  to ABR  Advances  on the last day of the  then  current  Interest
Period applicable thereto or at such earlier time as may be required by law. The
commitment  of any such  Lender with  respect to  Eurodollar  Advances  shall be
suspended  until  such  Lender  shall  notify the  Administrative  Agent and the
Borrower that the  circumstances  causing such suspension no longer exist.  Upon
receipt of such  notice by each of the  Administrative  Agent and the  Borrower,
such  Lender's  commitment  to make or  maintain  Eurodollar  Advances  shall be
reinstated.

          (d)   SUBSTITUTED   INTEREST   RATE.   In  the  event   that  (i)  the
Administrative  Agent  shall  have  determined  (which  determination  shall  be
conclusive  and  binding  upon the  Borrower)  that by reason  of  circumstances
affecting the interbank  eurodollar  market either adequate and reasonable means
do not exist for ascertaining the Eurodollar Rate applicable pursuant to Section
3.1 or (ii) the Required  Lenders shall have notified the  Administrative  Agent
that they have determined (which  determination  shall be conclusive and binding
on the Borrower)  that the  applicable  Eurodollar  Rate will not adequately and
fairly  reflect the cost to such Lenders of maintaining or funding loans bearing
interest based on such Eurodollar Rate, with respect to any portion of the Loans
that the Borrower has  requested be made as  Eurodollar  Advances or  Eurodollar
Advances that will result from the requested  conversion or  continuation of any
portion of the  Advances  into or of  Eurodollar  Advances  (each,  an "AFFECTED
Advance"),  the Administrative  Agent shall promptly notify the Borrower and the
Lenders (by telephone or otherwise, to be promptly confirmed in writing) of such
determination,  on or, to the extent practicable,  prior to the requested Credit
Extension  Date  or  Conversion  Date  for  such  Affected   Advances.   If  the
Administrative  Agent shall give such notice, (a) any Affected Advances shall be
made as ABR  Advances,  (b) the Advances (or any portion  thereof)  that were to
have been converted to Affected  Advances shall be converted to ABR Advances and
(c) any outstanding Affected Advances shall be converted, on the last day of the
then current  Interest Period with respect thereto,  to ABR Advances.  Until any
notice under clauses (i) or (ii), as the case may be, of this subsection (d) has
been withdrawn by the  Administrative  Agent (by notice to the Borrower promptly
upon  either  (x)  the   Administrative   Agent  having   determined  that  such
circumstances affecting the interbank eurodollar market no longer exist and that
adequate and  reasonable  means do exist for  determining  the  Eurodollar  Rate
pursuant to Section 3.1 or (y) the Administrative  Agent having been notified by
such Required  Lenders that  circumstances no longer render the Advances (or any
portion thereof) Affected  Advances),  no further  Eurodollar  Advances shall be
required to be made by the  Lenders,  nor shall the  Borrower  have the right to
convert all or any portion of the Loans to or as Eurodollar Advances.

          (e) PAYMENT; CERTIFICATES. Each payment pursuant to subsections (a) or
(b) above shall be made within 10 days after demand therefor, which demand shall
be  accompanied  by a  certificate  of the Credit Party  demanding  such payment
setting  forth the  calculations  of the  additional  amounts  payable  pursuant
thereto.  Each such  certificate  shall be conclusive  absent manifest error. No
failure by any Credit Party to demand,  and no delay in demanding,  compensation
for any  increased  cost shall  constitute  a waiver of its right to demand such
compensation  at any time,  provided  that such Credit  Party  shall  notify the
Borrower  of any such  increased  cost  within 90 days after the officer of such

                                      -42-
<PAGE>

Lender having primary  responsibility  for this Agreement has obtained knowledge
of such increased cost.

     3.6. TAXES.

          (a)  PAYMENTS  FREE OF TAXES.  All  payments  by or on  account of the
Borrower  under any Loan  Document to or for the account of a Credit Party shall
be made free and clear of, and without any  deduction or  withholding  for or on
account  of, any and all  present or future  Indemnified  Taxes or Other  Taxes,
provided that if the Borrower or any other Person is required by any law,  rule,
regulation,  order,  directive,  treaty or  guideline  to make any  deduction or
withholding  in  respect  of such  Indemnified  Tax or Other Tax from any amount
required to be paid by the  Borrower  to or on behalf of any Credit  Party under
any Loan Document  (each,  a "REQUIRED  PAYMENT"),  then (i) the Borrower  shall
notify the Administrative Agent and such Credit Party of any such requirement or
any  change  in any  such  requirement  as soon as the  Borrower  becomes  aware
thereof,  (ii) the Borrower shall pay such Indemnified Tax or Other Tax prior to
the date on which  penalties  attach  thereto,  such  payment to be made (to the
extent that the liability to pay is imposed on the Borrower) for its own account
or (to the extent that the  liability to pay is imposed on such Credit Party) on
behalf and in the name of such Credit  Party,  (iii) the  Borrower  shall pay to
such Credit Party an additional amount such that such Credit Party shall receive
on the due date  therefor an amount  equal to the  Required  Payment had no such
deduction or  withholding  been made or required,  and (iv) the Borrower  shall,
within 30 days after paying such  Indemnified  Tax or Other Tax,  deliver to the
Administrative Agent and such Credit Party satisfactory evidence of such payment
to the relevant Governmental Body.

          (b)  REIMBURSEMENT FOR TAXES AND OTHER TAXES PAID BY CREDIT PARTY. The
Borrower shall reimburse each Credit Party, within ten days after written demand
therefor,  for the full amount of all  Indemnified  Taxes or Other Taxes paid by
such  Credit  Party on or with  respect  to any  payment by or on account of any
obligation of the Borrower under the Loan Documents (including Indemnified Taxes
or Other Taxes imposed or asserted on or  attributable  to amounts payable under
this  Section) and any  penalties,  interest  and  reasonable  expenses  arising
therefrom or with respect  thereto (other than any such  penalties,  interest or
expenses  that are  incurred  by such  Credit  Party's  unreasonably  taking  or
omitting to take action with respect to such Indemnified  Taxes or Other Taxes),
whether or not such  Indemnified  Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant  Governmental  Body. A certificate as to the
amount of such payment or liability  delivered to the Borrower by a Credit Party
shall be conclusive  absent  manifest  error. In the event that any Credit Party
determines  that it received a refund or credit for  Indemnified  Taxes or Other
Taxes paid by the Borrower under this Section,  such Credit Party shall promptly
notify the  Borrower of such fact and shall remit to the  Borrower the amount of
such refund or credit.

          (c) FOREIGN CREDIT PARTIES.  Any Foreign Credit Party that is entitled
to an  exemption  from or  reduction  of  withholding  tax  under the law of the
jurisdiction  in which the  Borrower  is  located,  or any  treaty to which such
jurisdiction is a party, with respect to payments under the Loan Documents shall
deliver to the Borrower (with a copy to the  Administrative  Agent), at the time
or times  prescribed  by applicable  law,  such properly  completed and executed
documentation prescribed by applicable law (including Internal Revenue Form 4224
or Form 1001) or  reasonably  requested  by the  Borrower  as will  permit  such
payments to be made without withholding or at a reduced rate.

                                      -43-

     3.7. MITIGATION; REPLACEMENT LENDERS.

          (a) CHANGES OF LENDING  OFFICES.  If any Credit  Party (or its holding
company,  if any) requests  compensation  under Section  3.5(a) or (b) or if the
Borrower  is  required to pay an  additional  amount to any Credit  Party or any
Governmental  Body for the account of any Credit Party  pursuant to Section 3.6,
such Credit Party will, upon the request of the Borrower, use reasonable efforts
(subject to its overall policy  considerations) to designate a different lending
office for funding or booking its  Extensions  of Credit or to assign its rights
and obligations hereunder to another of its offices, branches or affiliates, if,
in its good faith judgment,  such  designation or assignment (i) would eliminate
or reduce future amounts  payable under Section 3.5(a) or (b) or Section 3.6, as
the case may be, (ii) would not subject  such Credit  Party to any  unreimbursed
cost or expense and (iii) would not otherwise be disadvantageous to such Lender.
The  Borrower  agrees to pay the  reasonable  costs  and  expenses  incurred  in
connection with any such designation or assignment and the Administrative  Agent
agrees that no  assignment  fee shall be payable to it pursuant to Section 12 in
connection  therewith.  Nothing in this Section  shall affect or postpone any of
the obligations of the Borrower to make the payments  required to a Credit Party
under  Section  3.5(a)  or  (b) or  Section  3.6,  incurred  prior  to any  such
designation or assignment.

          (b)  REPLACEMENT  OF LENDERS.  If (i) any Credit Party (or its holding
company,  if any) requests  compensation  under Section  3.5(a) or (b) or if the
Borrower  is  required to pay an  additional  amount to any Credit  Party or any
Governmental Body for the account of any Credit Party pursuant to Section 3.6 in
an  aggregate  amount in excess of $50,000,  or (ii) any Credit Party shall give
any notice to the  Borrower  or the  Administrative  Agent  pursuant  to Section
3.5(c),  then, in each such case,  provided that no Default shall then exist and
be continuing,  during the 90 day period after the receipt of such request,  the
Borrower  at  its  sole  cost,  expense  and  effort  may,  upon  notice  to the
Administrative  Agent,  require Lender to assign (in accordance with and subject
to the restrictions contained in Section 11.5) all of its rights and obligations
under the Loan  Documents to any other  Lender (or  affiliate  thereof),  or any
other Eligible  Institution  identified by the Borrower if such other Lender (or
affiliate  thereof)  or such  Eligible  Institution  agrees to assume all of the
obligations of such Lender for consideration equal to the outstanding  principal
amount of such Lender's  Loans,  together  with interest  thereon to the date of
such  transfer and all other amounts  payable  under the Loan  Documents to such
Lender  on or prior to the date of such  transfer  (including  any fees  accrued
hereunder  and any amounts which would be payable under Section 3.4 as if all of
such Lender's Loans were being prepaid in full on such date).  In the event of a
transfer to any other Eligible  Institution,  subject to the satisfaction of the
conditions of Section 11.5,  such Eligible  Institution  shall be a "Lender" for
all purposes hereunder. Without prejudice to the survival of any other agreement
of the Borrower hereunder,  the agreements of the Borrower contained in Sections
3.5, 3.6(b),  11.1(a) and 11.4 (without duplication of any payments made to such
Lender by the Borrower or such other Eligible Institution) shall survive for the
benefit of any Lender replaced under this Section with respect to the time prior
to  such  replacement.   In  connection  with  any  transfer  pursuant  to  this
subsection,  the Borrower  shall be obligated to pay the assignment fee referred
to in Section 11.5(b).

hereby makes the following representations and warranties to each Credit Party:

                                      -44-
<PAGE>

     4.1. SUBSIDIARIES; CAPITALIZATION.

          As of the  Second  Restatement  Date and  after  giving  effect to the
consummation of the  Transactions,  Arch has only the  Subsidiaries set forth on
Schedule 4.1. The issued and outstanding shares of each corporate  Subsidiary of
Arch are duly authorized,  validly issued,  fully paid and nonassessable and are
owned free and clear of any Liens,  except Permitted Liens. The interest of Arch
and any of its Subsidiaries in each of its  non-corporate  Subsidiaries is owned
free and clear of any Liens,  except Permitted  Liens.  The outstanding  capital
Stock of each  corporate  Subsidiary of Arch and the ownership  interest in each
non-corporate  Subsidiary  of Arch,  in each case as of the  Second  Restatement
Date, are as set forth on Schedule 4.1. The owner of each such interest and each
issue of capital Stock listed on Schedule 4.1 is the  registered  and beneficial
owner thereof.  None of the Borrower or any of its  Subsidiaries  has issued any
securities  convertible  into capital Stock (or other equity interest) and there
are no outstanding options or warrants to purchase capital Stock of the Borrower
or any such Subsidiary of any class or kind, and there are no agreements, voting
trusts or  understandings  with  respect  thereto or affecting in any manner the
sale, pledge,  assignment or other disposition  thereof,  including any right of
first refusal,  option,  redemption,  call or other rights with respect thereto,
whether  similar or dissimilar to any of the foregoing.  In addition,  as of the
Second  Restatement Date, Arch Canada is the only Foreign Subsidiary of Arch and
is not a Material Foreign Subsidiary.

     4.2. EXISTENCE AND POWER.

          The Borrower and each of its  Subsidiaries is duly organized,  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
incorporation  or formation,  has all requisite legal power and authority to own
its  Property  and to carry on its  business  as now  conducted,  and is in good
standing and authorized to do business in each jurisdiction in which the failure
to be so  authorized  could  reasonably  be expected to have a Material  Adverse
Effect.

     4.3. AUTHORITY AND EXECUTION.

          The  Borrower  and each of its  Subsidiaries  has full legal power and
authority  to enter  into,  execute,  deliver  and  carry  out the  terms of the
Transaction  Documents to which it is a party, and, in the case of the Borrower,
to make the borrowings  contemplated  hereby, to execute,  deliver and carry out
the terms of the Notes and to incur the obligations provided for therein, all of
which have been duly  authorized by all proper and  necessary  action and are in
full compliance with its Organizational  Documents. The Borrower and each of its
Subsidiaries has duly executed and delivered the Transaction  Documents to which
it is a party.

     4.4. GOVERNMENTAL BODY APPROVALS.

          Except as set forth on Schedule  4.4, no  consent,  authorizations  or
approval  of,  filing  with,  notice  to, or  exemption  by,  stockholders,  any
Governmental  Body or any  other  Person  (except  for  those  which  have  been
obtained,  made or given) is required to authorize, or is required in connection
with the  execution,  delivery and  performance  by the Borrower and each of its
Subsidiaries  of any of the  Transaction  Documents to which it is a party or is
required  as a  condition  to  the  validity  or  enforceability  of  any of the
Transaction  Documents.  No provision of any applicable statute,  law (including

                                      -45-
<PAGE>

any  applicable  usury or similar law),  rule or regulation of any  Governmental
Body will  prevent  the  execution,  delivery or  performance  of, or affect the
validity of, any of the Transaction Documents.

     4.5. BINDING AGREEMENT.

          The Transaction Documents  constitute,  and the Notes, when issued and
delivered  pursuant hereto for value received,  will  constitute,  the valid and
legally  binding  obligations of the Borrower and each of its  Subsidiaries,  in
each case to the extent that it is a party  thereto,  enforceable  in accordance
with their respective  terms,  except as such  enforceability  may be limited by
applicable  bankruptcy,   insolvency,   reorganization  or  other  similar  laws
affecting the enforcement of creditors' rights generally.

     4.6. LITIGATION.

          Except as set forth on Schedule  4.6,  there are no actions,  suits or
proceedings at law or in equity or by or before any  Governmental  Body (whether
or not  purportedly on behalf of the Borrower or any of its  Subsidiaries or any
other Loan  Party)  pending or, to the  knowledge  of the  Borrower,  threatened
against the Borrower or any of its  Subsidiaries  or any other Loan Party or any
of their  respective  Properties or rights,  which (i) if adversely  determined,
could reasonably be expected to have a Material Adverse Effect or (ii) call into
question the validity or enforceability of any of the Transaction Documents.

     4.7. NO CONFLICTING AGREEMENTS.

          Except as set forth on Schedule  4.7,  neither the Borrower nor any of
its  Subsidiaries  is  in  default  under  any  mortgage,  indenture,  contract,
agreement,  judgment,  decree  or order to which it is a party or by which it or
any of its Property is bound, which defaults, taken as a whole, could reasonably
be  expected  to have a Material  Adverse  Effect.  The  execution,  delivery or
carrying out of the terms of the  Transaction  Documents  will not  constitute a
default  under,  conflict  with,  require any consent under (other than consents
which  have been  obtained)  or  result in the  creation  or  imposition  of, or
obligation  to create,  any Lien upon the Property of the Borrower or any of its
Subsidiaries  pursuant to the terms of any such mortgage,  indenture,  contract,
agreement, judgment, decree or order, which defaults, conflicts and consents, if
not obtained,  taken as a whole, could reasonably be expected to have a Material
Adverse Effect. The execution, delivery or carrying out of the terms of the Loan
Documents  will not  constitute  a default  under,  conflict  with,  require any
consent under (other than consents which have been obtained),  the  Subordinated
Indenture,  the Parent  Discount  Notes  Indenture,  either of the Existing Arch
Indentures  or the  Arch  12  3/4%  Indenture,  OR  result  in the  creation  or
imposition of, or obligation to create,  any Lien (other than  Permitted  Liens)
upon  the  Property  of  the  Parent  or  Arch  pursuant  to  the  terms  of the
Subordinated  Indenture,  the Parent  Discount  Notes  Indenture,  either of the
Existing Arch Indentures or the Arch 12 3/4% Indenture.

     4.8. TAXES.

          Each of the Borrower and each of its  Subsidiaries has filed or caused
to be filed all tax  returns  required  to be filed  and has  paid,  or has made
adequate  provision for the payment of, all taxes shown to be due and payable on
said  returns or in any  assessments  made  against it (other  than those  being
contested as required under Section 7.4) which would be material to the Borrower
or any of its  Subsidiaries,  and no tax Liens  have  been  filed  with  respect

                                      -46-
<PAGE>

thereto  except  Permitted  Liens  described  in Section  8.2(i).  The  charges,
accruals and reserves on the books of the Borrower and each of its  Subsidiaries
with  respect to all  federal,  state,  local and other  taxes are,  to the best
knowledge of the Borrower,  adequate for the payment of all such taxes,  and the
Borrower does not know of any unpaid assessment which is due and payable against
it or  any  of its  Subsidiaries  or  any  claims  being  asserted  which  could
reasonably be expected to have a Material Adverse Effect, except such thereof as
are being  contested  as required  under  Section  7.4,  and for which  adequate
reserves have been set aside in accordance with GAAP.

     4.9. COMPLIANCE WITH APPLICABLE LAWS.

          Neither the  Borrower nor any of its  Subsidiaries  is in default with
respect to any  judgment,  order,  writ,  injunction,  decree or decision of any
Governmental  Body which default could reasonably be expected to have a Material
Adverse  Effect.  The Borrower and each of its  Subsidiaries is complying in all
material   respects  with  all  applicable   statutes  and  regulations  of  all
Governmental  Bodies,  including  ERISA and  Environmental  Laws, a violation of
which could reasonably be expected to have a Material Adverse Effect.

     4.10. INVESTMENT COMPANIES AND OTHER REGULATED ENTITIES.

          Neither  the  Borrower,   any  of  its  Subsidiaries  nor  any  Person
controlled by, controlling, or under common control with, the Borrower or any of
its  Subsidiaries,  is (i) an "investment  company" as defined in, or subject to
regulation  under,  the  Investment  Company  Act of 1940,  as  amended,  (ii) a
"holding  company" as defined  in, or subject to  regulation  under,  the Public
Utility  Holding  Company Act of 1935 or the Federal  Power Act, as amended,  or
(iii)  subject to any statute or  regulation  which  prohibits or restricts  the
incurrence of Indebtedness for borrowed money, including statutes or regulations
relative to common or  contract  carriers  or to the sale of  electricity,  gas,
steam, water, telephone, telegraph or other public utility services.

     4.11. PROPERTIES.

          Each  of the  Borrower  and  each of its  Subsidiaries  has  good  and
marketable title to, or valid leasehold interests in, all of its property,  real
and personal,  material to its business,  subject to no Liens,  except Permitted
Liens and except  for minor  defects  in title  that do not  interfere  with its
ability to conduct  its  business  as  currently  conducted  or to utilize  such
properties for their intended purposes.

     4.12. FCC MATTERS.

          The  Borrower  and each of its  Subsidiaries  (i) has duly and  timely
filed all filings which are required to be filed by it under the  Communications
Act,  the  failure  to file of which  could  reasonably  be  expected  to have a
Material Adverse Effect and (ii) is in all material  respects in compliance with
the Communications  Act, including the rules and regulations of the FCC relating
to the carriage of radio common carrier signals, the failure to be in compliance
with which could reasonably be expected to have a Material Adverse Effect.

                                      -47-
<PAGE>

     4.13. FEDERAL RESERVE REGULATIONS.

          (a) Neither the Borrower nor any Subsidiary is engaged principally, or
as one of its important activities,  in the business of extending credit for the
purpose of purchasing or carrying any Margin Stock.  After giving effect to each
Transaction  and the  making of each  Extension  of  Credit,  Margin  Stock will
constitute less than 25% of the assets (as determined by any reasonable  method)
of the Borrower and the Subsidiaries.

          (b) No part of the  proceeds of any  Extension of Credit will be used,
whether  directly  or  indirectly,  and  whether  immediately,  incidentally  or
ultimately, for any purpose that entails a violation of, or that is inconsistent
with, the provisions of Regulation U or X.

     4.14. TARIFFS.

          No action to change, alter, rescind or otherwise terminate the tariffs
containing service regulations or any rates and charges for radio common carrier
services which, if adversely  determined,  would have a Material Adverse Effect,
is  pending  or known by the  Borrower  or any of its  Subsidiaries  to be under
consideration.

     4.15. NO MISREPRESENTATION.

          No representation  or warranty  contained herein and no certificate or
report furnished or to be furnished pursuant to any of the Transaction Documents
by any Loan  Party in  connection  with the  transactions  contemplated  thereby
contains  or will  contain a  misstatement  of  material  fact,  or, to the best
knowledge of the Borrower,  omits or will omit to state a material fact required
to be stated in order to make the  statements  herein or therein  contained  not
misleading in the light of the  circumstances  under which made. With respect to
projections or pro-forma financial  statements  furnished by the Borrower or any
of its  Subsidiaries,  such  projections  have been or will be  prepared in good
faith on the assumptions  stated therein,  which assumptions are or will be fair
and reasonable in light of the circumstances existing at the time of delivery of
such  projections  or statements  and  represent,  at the time of delivery,  the
Borrower or such Subsidiary's best estimate of its future financial performance.

     4.16. PLANS.

          None  of  the  Borrower,  any  of its  Subsidiaries  or  any  Commonly
Controlled Entity maintains or is obligated to contribute to any Single Employer
Plan or Multiemployer  Plan.  Since the effective date of ERISA,  there have not
been,  nor are there now existing,  any events or conditions  which would permit
any Single  Employer Plan at any time  maintained  by the  Borrower,  any of its
Subsidiaries or any Commonly  Controlled Entity or, to the best knowledge of the
Borrower,  any Multiemployer Plan to which the Borrower, any of its Subsidiaries
or any Commonly Controlled Entity at any time contributed to be terminated under
circumstances which would cause the Lien provided under Section 4068 of ERISA to
attach to the Property of the Borrower or any of its Subsidiaries.

                                      -48-
<PAGE>

     4.17. BURDENSOME OBLIGATIONS.

          Neither  the  Borrower  nor any of its  Subsidiaries  is a party to or
bound by any franchise,  agreement,  deed, lease or other instrument, or subject
to any legal restriction which, in the opinion of the management of the Borrower
or such Subsidiary, is so unusual or burdensome, in the context of its business,
as in the foreseeable future might materially and adversely affect or impair the
revenue of the Borrower and its Subsidiaries taken as a whole, or Operating Cash
Flow, or the ability of the Borrower or any of its Subsidiaries to perform their
respective obligations under the Loan Documents. The Borrower does not presently
anticipate that future  expenditures by the Borrower or any of its  Subsidiaries
needed to meet the  provisions of federal or state  statutes,  orders,  rules or
regulations  will be so  burdensome  as to affect  or  impair,  in a  materially
adverse  manner,  the  business or  condition,  financial or  otherwise,  of the
Borrower and its Subsidiaries taken as a whole.

     4.18. FINANCIAL STATEMENTS.

          (a) The Parent and Arch have heretofore furnished to each Credit Party
a copy of their  respective  (A) Forms 10-K for the fiscal year ending  December
31, 1997,  containing the audited  Consolidated balance sheets of the Parent and
its Subsidiaries and of Arch and its Subsidiaries,  respectively, as of December
31, 1996 and December  31,  1997,  and the related  Consolidated  statements  of
operations,  stockholder's equity and cash flows for the periods then ended, and
(B) Forms 10-Q for the fiscal  quarter  ended  March 31,  1998,  containing  the
unaudited  Consolidated balance sheets of the Parent and its Subsidiaries and of
Arch and its Subsidiaries,  respectively, for such fiscal quarter, together with
the related Consolidated  statements of operations and cash flows for the fiscal
quarter then ended.  Such financial  statements  present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Parent,  the Borrower and their  consolidated  Subsidiaries as of such dates and
for such periods in accordance with GAAP,  subject to year-end audit adjustments
and the absence of footnotes in the case of the quarterly statements referred to
above.  Except as fully  reflected in such  financial  statements,  there are no
material  liabilities  or  obligations  with  respect  to  Arch  or  any  of its
Subsidiaries of any nature whatsoever (whether absolute, contingent or otherwise
and whether or not due).

          (b) Since December 31, 1997, except for the Transactions,  each of the
Parent and each of its  Subsidiaries  has  conducted  its  business  only in the
ordinary course and there has been no Material Adverse Change.

     4.19. ENVIRONMENTAL MATTERS.

          Neither the  Borrower  nor any of its  Subsidiaries  (i) has  received
written  notice or  otherwise  learned  of any  claim,  demand,  action,  event,
condition,  report or  investigation  indicating or concerning  any potential or
actual  liability  arising in connection  with (a) any non-  compliance  with or
violation of the  requirements of any applicable  Environmental  Laws or (b) the
release or  threatened  release of any toxic or  hazardous  waste,  substance or
constituent, or other hazardous substance into the environment, (ii) to the best
knowledge of the Borrower,  has any threatened or actual liability in connection
with  the  release  or  threatened  release  of any  toxic or  hazardous  waste,
substance or  constituent,  or other hazardous  substance into the  environment,
(iii) has  received  notice of any  federal  or state  investigation  evaluating
whether  any  remedial  action is needed to respond  to a release or  threatened
release of any toxic or  hazardous  waste,  substance  or  constituent  or other

                                      -49-
<PAGE>

hazardous  substance into the  environment  for which the Borrower or any of its
Subsidiaries is or may be liable,  or (iv) has received notice that the Borrower
or any of its Subsidiaries is or may be liable to any Person under CERCLA or any
analogous state law, which in the case of this Section 4.19,  individually or in
the aggregate  could  reasonably be expected to have a Material  Adverse Effect.
The  Borrower  and each of its  Subsidiaries  is in  compliance  in all material
respects with the  financial  responsibility  requirements  of federal and state
environmental  laws to the extent  applicable,  including  those contained in 40
C.F.R., parts 264 and 265, subpart H, and any analogous state law.

     4.20. FRANCHISES, INTELLECTUAL PROPERTY, ETC.

          The Borrower and each of its  Subsidiaries  possesses or has the right
to use all franchises, Intellectual Property, licenses, permits and other rights
as are material and necessary for the conduct of its business,  and with respect
to which it is in compliance in all material  respects,  with no known  conflict
with the valid  rights of others  which could  reasonably  be expected to have a
Material  Adverse  Effect.  No event has occurred  which permits or, to the best
knowledge  of the  Borrower,  after  notice  or  lapse  of time or  both,  could
reasonably  be expected to permit,  the  revocation or  termination  of any such
franchise,  Intellectual  Property,  license,  permit  or other  right and which
revocation  or  termination  could  reasonably  be  expected  to have a Material
Adverse Effect.

     4.21. SOLVENCY

          The Borrower and each of its  Subsidiaries is, and after giving effect
to the  incurrence  of  all  Indebtedness  under  the  Loan  Documents  and  the
consummation of the Transactions will be, Solvent.

     4.22. ABSENCE OF CERTAIN RESTRICTIONS.

          Except for the Loan Documents, the Loan Documents under and as defined
in the  Tranche A and  Tranche C Credit  Agreement,  the Parent  Discount  Notes
Indenture,  the Existing  Arch  Indentures,  the Arch 12 3/4%  Indenture and any
Replacement  Indenture,  NO indenture,  certificate of designation for preferred
Stock,  agreement  or  instrument  to  which  the  Parent,  Arch  or  any of its
Subsidiaries  is a party,  prohibits or restrains,  directly or indirectly,  the
payment of dividends or other payments to Arch or any of its Subsidiaries.

     4.23. INSURANCE.

          The Borrower's and its Subsidiaries'  insurance  policies are and will
be  sufficient  for  compliance  with  all  requirements  of law as  well as for
compliance with all agreements to which the Borrower or any of its  Subsidiaries
is a party,  and neither the Borrower nor any of its  Subsidiaries  suffers self
insurance for any material risks.

     4.24. PARI PASSU OBLIGATIONS.

          The  obligations  of Arch  under the Loan  Documents  to which it is a
party are pari passu with Arch's  obligations under the Existing Arch Indentures
and the Arch 12 3/4% Indenture.

     4.25. YEAR 2000 ISSUE.

          The Borrower and its Subsidiaries have reviewed the effect of the Year
2000 Issue on the computer software, hardware and firmware systems and equipment
containing  embedded microchips owned or operated by or for the Borrower and its
Subsidiaries or used or relied upon in the conduct of their business  (including
systems and equipment  supplied by others or with which such computer systems of
the Borrower and its Subsidiaries interface).  The costs to the Borrower and its
Subsidiaries of any reprogramming required as a result of the Year 2000 Issue to
permit the proper  functioning  of such  systems  and  equipment  and the proper
processing of data, and the testing of such reprogramming, and of the reasonably
foreseeable  consequences  of the Year 2000 Issue to the  Borrower or any of its
Subsidiaries  (including  reprogramming  errors  and the  failure  of systems or
equipment  supplied  by  others)  are (to the  best  of the  Borrower's  and its
Subsidiaries'  knowledge,  with respect to such computer  hardware,  software or
systems  used or relied upon in the conduct of their  business  but not owned or
leased by the Borrower or any of its  Subsidiaries)  not reasonably  expected to
result in a Default or Event of Default or to have a Material Adverse Effect.

<PAGE>

which insurance shall be on terms reasonably  satisfactory to the Administrative
Agent. Promptly upon request therefor,  the Borrower will deliver or cause to be
delivered to the  Administrative  Agent originals or duplicate  originals of all
such policies of insurance.  All such  insurance  policies  shall be endorsed to
provide  that,  in respect of the  interests of the  Collateral  Agent:  (i) the
Collateral  Agent shall be an  additional  insured and, with respect to property
insurance,  sole loss payee in respect of each claim  relating to such  tangible
personal  Property and  resulting in a payment under any such  insurance  policy
exceeding $250,000,  (ii) thirty days' prior written notice of any cancellation,
reduction of amounts  payable,  or any changes and amendments  shall be given to
the Collateral Agent, except that ten days' prior written notice of cancellation
shall be given to the Collateral Agent if cancellation  results from the failure
to pay premiums,  and (iii) the Collateral  Agent shall have the right,  but not
the obligation,  to pay any premiums due or to acquire other such insurance upon
the failure of the Borrower or such  Subsidiary to pay the same or to so insure.

agrees,  promptly upon its receipt  thereof,  to pay over to the Borrower or the
appropriate  Subsidiary  the  proceeds of such payment to enable the Borrower or
such  Subsidiary  to repair,  restore or replace  the  Property  subject to such
claim.  To the extent  that the  Borrower or such  Subsidiary  does not elect to
repair,  restore or replace such Property, an amount equal to the proceeds which
are not employed to repair, restore or replace such Property shall be applied as
required  by Section  2.4.  If a Default or Event of Default  shall  exist,  the
Administrative  Agent or, if applicable  pursuant to the  applicable  Collateral
Document,  the  Collateral  Agent,  shall hold the  proceeds of such  payment as
Collateral  (to the extent of its security  interest in such Property) and apply
such proceeds in accordance with the provisions thereof.

          (c)  CONCURRENT  INSURANCE.  Neither  the  Borrower  nor  any  of  the
Subsidiaries   shall  take  out  separate   insurance   concurrent  in  form  or
contributing  in the event of loss with that required to be maintained  pursuant
to subsection (b) above unless the Administrative Agent has approved the carrier
and the form and content of the insurance policy, including, without limitation,
naming  of the  Collateral  Agent as  additional  insured  and sole  loss  payee
thereunder.

     7.6. PAYMENT OF INDEBTEDNESS AND PERFORMANCE OF OBLIGATIONS.

          Pay and discharge when due, and cause each of its  Subsidiaries  so to
do, all lawful  Indebtedness,  obligations  and claims for labor,  materials and
supplies  or  otherwise  which,  if unpaid,  might (i) have a  Material  Adverse
Effect,  or (ii)  become  a Lien  upon  the  Property  of the  Borrower  or such
Subsidiary  other than a Permitted Lien,  unless and to the extent only that the
validity of such  Indebtedness,  obligation  or claim shall be contested in good
faith and by  appropriate  proceedings  diligently  conducted by the Borrower or
such Subsidiary, and that any such contested Indebtedness, obligations or claims
shall not constitute,  or create,  a Lien on any Property of the Borrower or any
of its Subsidiaries senior to any Lien granted to the Administrative Agent under
the  Collateral  Documents  on such  Property,  and  further  provided  that the
Borrower shall give the  Administrative  Agent prompt notice of any such contest
and that such reserve or other appropriate provision as shall be required by the
Accountants in accordance with GAAP shall have been made therefor.

the Collateral  Agent's option,  all other filings and to give all other notices
as it shall reasonably deem necessary with respect to any of the Collateral, all
of which may be done with or without the signature of the Borrower or any of its
Subsidiaries.  The foregoing power  constitutes a power coupled with an interest
which shall survive until all of the  obligations  under the Loan Documents have
been  indefeasibly  paid  in  full in cash  and  the  Credit  Agreement  and the
Commitments have been terminated.

Document, UCC-1 Financing Statement, Powers of Attorney or other documents shall
also constitute a direction to deliver the  corresponding  document executed for
the benefit of the Applicable Arch Indenture Trustees.

the proper  functioning  of such  computer  systems and other  equipment and the
testing of such  systems and  equipment,  as so  reprogrammed,  except where the

Borrower shall provide,  and shall cause each of its Subsidiaries to provide, to
the  Administrative  Agent  reasonable  assurance  of its  compliance  with  the
preceding sentence.

the Parent or any of its  Subsidiaries  (other  than an order  requested  by the
Parent or any of its  Subsidiaries  in respect  of a  transaction  permitted  by
Section 7.3); or

               (j) Any  judgment  or  decree  against  the  Parent or any of its

delay,  prevent or otherwise  impede the  performance or enforcement of any Loan
Document.

          In the event that the Commitments  shall have terminated or the Loans,
all accrued and unpaid  interest  thereon and all other  amounts owing under the
Loan Documents  shall have become due and payable  pursuant to the provisions of

the Administrative Agent in the following manner and order:

               (i) first, to reimburse the Administrative Agent and the Lenders,

10. THE ADMINISTRATIVE AGENT

          Each  of  the  Lenders   hereby   irrevocably   appoints  BNY  as  the
Administrative  Agent  and  authorizes  the  Administrative  Agent to take  such
actions on its behalf and to exercise  such powers as are delegated to it by the
terms hereof, together with such actions and powers as are reasonably incidental
thereto.

     10.2. INDIVIDUAL CAPACITY.

          The Person serving as the  Administrative  Agent  hereunder shall have
the same rights and powers in its  capacity as a Lender as any other  Lender and
may exercise the same as though it were not the  Administrative  Agent, and such
Person and its Affiliates may accept  deposits from, lend money to and generally
engage  in any  kind of  business  with the  Borrower,  any  Subsidiary,  or any
Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

     10.3. EXCULPATORY PROVISIONS.

          The  Administrative  Agent  shall not have any  duties or  obligations
except those expressly set forth herein.  Without limiting the generality of the
foregoing, (1) the Administrative Agent shall not be subject to any fiduciary or
other  implied  duties,  regardless  of whether a Default  has  occurred  and is
continuing,  (2) the  Administrative  Agent  shall not have any duty to take any
discretionary action or exercise any discretionary  powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage  of the  Lenders as shall be  necessary  under the  circumstances  as
provided in Section  11.1),  and (3) except as expressly set forth  herein,  the
Administrative  Agent  shall  not have any duty to  disclose,  and  shall not be
liable for the failure to disclose,  any information relating to the Borrower or
any  Subsidiary  that is  communicated  to or  obtained  by the bank  serving as
Administrative   Agent  or  any  of  its   Affiliates  in  any   capacity.   The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary  under the  circumstances  as
provided  in  Section  11.1) or in the  absence of its own gross  negligence  or
willful  misconduct.  The  Administrative  Agent  shall  be  deemed  not to have
knowledge of any Default unless and until written notice thereof is given to the
Administrative   Agent  by  the  Borrower  or  another   Credit  Party  and  the
Administrative  Agent shall not be responsible for or have any duty to ascertain
or inquire  into (i) any  statement,  warranty or  representation  made in or in
connection with this Agreement, (ii) the contents of any certificate,  report or
other  document  delivered  hereunder  or  in  connection  herewith,  (iii)  the
performance or observance of any of the covenants,  agreements or other terms or
conditions set forth herein, (iv) the validity, enforceability, effectiveness or

be delivered to the Administrative Agent.

     10.4. RELIANCE BY ADMINISTRATIVE AGENT.

          The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement,  instrument,  document or other writing  believed by it to be genuine
and to have been signed or sent by the proper Person. The  Administrative  Agent
also may rely upon any statement  made to it orally or by telephone and believed
by it to be made by the proper  Person,  and shall not incur any  liability  for
relying thereon.  The  Administrative  Agent may consult with legal counsel (who
may be counsel  to the  Borrower),  independent  accountants  and other  experts
selected by it, and shall not be liable for any action  taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

     10.5. DELEGATION.

          The  Administrative  Agent  may  perform  any and all its  duties  and
exercise  its  rights  and  powers by or  through  any one or more  sub-  agents
appointed by the  Administrative  Agent,  provided that no such delegation shall
serve as a release of the Administrative  Agent or waiver by the Borrower of any
rights hereunder.  The  Administrative  Agent and any such sub-agent may perform
any and all its  duties  and  exercise  its  rights  and  powers  through  their
respective Related Parties. The exculpatory  provisions of this Section 10 shall
apply to any such  sub-agent  and to the Related  Parties of the  Administrative
Agent and any such sub-agent,  and shall apply to their respective activities in

                                      -78-
<PAGE>

connection with the syndication of the credit facilities  provided for herein as
well as activities as Administrative Agent.

     10.6. RESIGNATION; SUCCESSOR ADMINISTRATIVE AGENT.

          Subject   to  the   appointment   and   acceptance   of  a   successor
Administrative  Agent as provided in this Section,  the Administrative Agent may
resign at any time by  notifying  the  Lenders and the  Borrower.  Upon any such
resignation, the Required Lenders shall have the right, with the written consent
of the  Borrower  (such  consent not to be  unreasonably  withheld and not to be
required  during the continuance of an Event of Default) to appoint a successor.
If no successor  shall have been so appointed by the Required  Lenders and shall
have accepted such appointment within 30 days after the retiring  Administrative
Agent gives notice of its resignation,  then the retiring  Administrative  Agent
may, on behalf of the Lenders,  appoint a successor  Administrative  Agent which
shall be a bank with an office in New York,  New York,  or an  Affiliate  of any
such bank.  Upon the  acceptance  of its  appointment  as  Administrative  Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights,  powers,  privileges  and duties of the retiring  Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and  obligations  hereunder.  The fees  payable by the  Borrower  to a successor
Administrative  Agent  shall  be the same as those  payable  to its  predecessor
unless  otherwise  agreed  between the  Borrower and such  successor.  After the
Administrative Agent's resignation hereunder,  the provisions of this Section 10
and  Section  11.4 shall  continue  in effect for the  benefit of such  retiring
Administrative  Agent,  its sub-agents and their  respective  Related Parties in
respect of any actions  taken or  permitted  to be taken by any of them while it
was acting as Administrative Agent.

     10.7. NON-RELIANCE ON OTHER CREDIT PARTIES.

          Each Credit Party acknowledges that it has,  independently and without
reliance  upon the  Administrative  Agent or any other Credit Party 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  Credit  Party also
acknowledges  that  it  will,   independently  and  without  reliance  upon  the
Administrative  Agent or any other Credit Party 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,
any related agreement or any document furnished hereunder or thereunder.

     10.8.   COLLATERAL   AGENT,   MANAGING   AGENTS,   SYNDICATION   AGENT  AND
DOCUMENTATION AGENT.

          The Collateral Agent, in its capacity as Collateral Agent,  shall have
only the duties and  obligations  expressly  set forth in the Loan  Documents to
which it is a party. The Managing Agents,  Syndication  Agent and  Documentation
Agent  shall have no duties or  obligations  under the Loan  Documents  in their
respective  capacities as Managing Agents,  Syndication  Agent and Documentation
Agent.   The  Collateral   Agent,   Managing  Agents,   Syndication   Agent  and
Documentation  Agent shall be entitled to the same protections,  indemnifies and
rights,  and  subject  to the same  standards  with  respect  to their  actions,
inactions and duties, as the Administrative Agent.

11. MISCELLANEOUS

     11.1. AMENDMENTS AND WAIVERS.

          (a) No failure to exercise and no delay in exercising,  on the part of
any Credit Party, any right,  remedy, power or privilege under any Loan Document
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any right, remedy, power or privilege under any Loan Document preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies,  powers and privileges under the Loan Documents
are cumulative and not exclusive of any rights, remedies,  powers and privileges
provided by law. No waiver of any  provision of any Loan  Document or consent to
any departure by any Loan Party therefrom shall in any event be effective unless
the same shall be  permitted  by this  Section,  and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given.  Without  limiting the generality of the foregoing,  the making of a Loan
shall not be  construed as a waiver of any  Default,  regardless  of whether any
Credit Party may have had notice or knowledge of such Default at the time.

          (b)  Notwithstanding  anything to the  contrary  contained in any Loan
Document,  with the written consent of the Required Lenders,  the Administrative
Agent and the  appropriate  parties to the Loan Documents  (other than the other
Credit  Parties)  may,  from  time  to  time,  enter  into  written  amendments,
supplements  or  modifications  thereof  and,  with the consent of the  Required
Lenders,  the  Administrative  Agent on behalf of the other Credit Parties,  may
execute  and  deliver  to any such  parties  a  written  instrument  waiving  or
consenting  to  the  departure  from,  on  such  terms  and  conditions  as  the
Administrative Agent may specify in such instrument,  any of the requirements of
the Loan Documents or any Default and its consequences;  provided, however, that
no such amendment, supplement, modification, waiver or consent shall:

               (i) increase  the Tranche B  Commitment  of any Tranche B Lender,
     without such Lender's consent;

               (ii) unless agreed to by each Credit Party affected thereby,  (A)
     reduce the principal amount of any Extension of Credit,  or reduce the rate
     of interest thereon,  or reduce any fees or other obligations payable under
     the Loan  Documents,  or (B) extend any date  (including any Maturity Date)
     fixed for the payment of any  principal of or interest on any  Extension of
     Credit, any fees, or any other obligation payable under the Loan Documents;

               (iii) unless agreed to by all of the Tranche A Lenders, Tranche B
     Lenders  and  Tranche C  Lenders:  (A)  increase  the  Aggregate  Tranche B
     Commitments,  (B) change this Section  11.1,  the  definition  of "Minority
     Lenders" or "Required Lenders" or any other provision hereof specifying the
     number or  percentage  of Lenders  required  to waive,  amend or modify any
     rights hereunder or make any determination or grant any consent  hereunder,
     (C) change Section 2.9 in a manner that would alter the pro rata sharing of
     payments required  thereby,  (D) consent to any assignment or delegation by
     any Loan Party of any of its rights or obligations under any Loan Document,
     (E)  release  any  Subsidiary  Guarantor  from its  obligations  under  the
     Subsidiary  Guaranty,  Arch from its obligations under Arch Guaranty or the
     Parent from its  obligations  under the Parent  Guaranty  (except as may be

                                      -80-
<PAGE>

     expressly  permitted  thereunder or  hereunder),  or (F) release any of the
     Collateral  from the Liens of the  Collateral  Documents,  except as may be
     expressly permitted thereunder or hereunder,

               (iv) without the consent of Lenders of each Class having not less
     than  66-2/3% of the (A)  Aggregate  Tranche A  Commitments  in the case of
     Tranche  A  Lenders,  (B)  Aggregate  Tranche B  Commitments  (or after the
     Tranche B Conversion Date, the Aggregate Tranche B Exposure) in the case of
     Tranche B Lenders and (C) the outstanding principal amount of the Tranche C
     Loans in the case of  Tranche C  Lenders,  no such  amendment,  supplement,
     modification,  waiver or consent shall change the provisions of Section 2.4
     relating to the  allocation of  prepayments  to the Tranche B Loans and the
     reduction of the Aggregate Tranche B Commitments, and

               (v)  unless  agreed  to  by  the  Administrative   Agent  or  the
     Collateral Agent amend,  modify or otherwise affect the rights or duties of
     the Administrative Agent or the Collateral Agent,  respectively,  under the
     Loan Documents.

          Any such amendment, supplement,  modification, waiver or consent shall
apply  equally to each Credit  Party and shall be binding upon each Credit Party
and each Loan Party to the applicable Loan Document, and upon all future holders
of the Notes. In the case of any waiver,  the Credit Parties and each Loan Party
party to the applicable Loan Document shall be restored to their former position
and rights hereunder and under the outstanding Notes and other Loan Documents to
the extent provided for in such waiver,  and any Default waived shall not extend
to any subsequent or other Default, or impair any right consequent thereon.

     11.2. NOTICES.

          All notices, requests and demands to or upon the respective parties to
the Loan  Documents to be effective  shall be in writing and,  unless  otherwise
expressly provided therein, shall be deemed to have been duly given or made when

     signature  page hereto or, in the  Assignment  or  Acceptance  Agreement or
     other instrument pursuant to which it became a Lender;

provided,  however, that any notice,  request or demand by the Borrower pursuant
to Sections  2.2,  2.3, 2.4 or 3.3 shall not be effective  until  received.  Any
party to a Loan Document may rely on signatures of the parties thereto which are
transmitted  by facsimile or other  electronic  means as fully as if  originally

     11.3. SURVIVAL.

          All covenants, agreements,  representations and warranties made by the
Borrower  herein  and in the  certificates  or other  instruments  delivered  in
connection  with or pursuant to this Agreement  shall be considered to have been
relied upon by the other  parties  hereto and shall  survive the  execution  and

the time any credit is extended hereunder.

     11.4. EXPENSES; INDEMNITY.

          (a) The Borrower agrees,  on demand therefor and whether any Extension

including  the  reasonable  fees,  charges  and  disbursements  of  counsel,  in
connection  with  the  development,   preparation,  execution,  syndication  and
administration  of, the Loan Documents  (including any amendment,  supplement or

documents  prepared  in  connection   therewith  and  the  consummation  of  the
transactions contemplated thereby and (ii) to pay or reimburse each Credit Party

PERSON")  against,  and hold each Indemnified  Person harmless from, any and all
losses, claims, damages, penalties,  liabilities and related expenses, including
the fees,  charges and  disbursements  of any  counsel,  incurred by or asserted
against any  Indemnified  Person in connection with or in any way arising out of
any Loan Document, any other Transaction Document or any Transaction,  including
as a result of (i) any breach by the Borrower of the terms of any Loan Document,
the use of proceeds of any  Extension  of Credit or any action or failure to act
on the part of the Borrower,  (ii) the consummation or proposed  consummation of
the  Transactions  or any  other  transactions  contemplated  hereby,  (iii) any

     11.5. SUCCESSORS AND ASSIGNS

          (a) The Loan Documents  shall be binding upon and inure to the benefit
of each of the parties  thereto,  and their  respective  successors and assigns,
except that no Loan Party may assign or otherwise  transfer any of its rights or
obligations  hereunder  without the prior  written  consent of each Credit Party
(and any such  attempted  assignment  or transfer  without such consent shall be

provided that:

               (A)  except  in the  case  of an  assignment  to a  Lender  or an

Acceptance  Agreement together with the assignment fee therefor and the consents
required to such assignment,  if required, the Administrative Agent shall record
the same and execute not less than two copies of such  Assignment and Acceptance
Agreement in the  appropriate  place,  deliver one such copy to the assignor and
one such copy to the assignee,  and deliver one photocopy thereof,  as executed,
to the Borrower.  From and after the Assignment Effective Date specified in, and

                                      -83-

as defined in, such Assignment and Acceptance Agreement, the assignee thereunder
shall,  unless  already a  Lender,  become a party  hereto  and  shall,  for all
purposes of the Loan Documents, be deemed a "Lender" and, to the extent provided
in such  Assignment and Acceptance  Agreement,  the assignor  Lender  thereunder
shall be released from its  obligations  under this Agreement and the other Loan
Documents.  The Borrower agrees that, if requested, in connection with each such
assignment,  it shall at its own cost and  expense  execute  and  deliver to the
Administrative  Agent or such assignee a Note, each payable to the order of such
assignee and dated the Second Restatement Date. The  Administrative  Agent shall
be entitled to rely upon the representations and warranties made by the assignee
under each Assignment and Acceptance Agreement.

          (c) Each  Lender  may grant  participations  in all or any part of its
rights  and  obligations  under  the  Loan  Documents  to one or  more  Eligible
Institutions,  provided that (i) such Lender's  obligations under this Agreement
and the other Loan  Documents  shall  remain  unchanged,  (ii) such Lender shall
remain solely  responsible  to the other parties to this Agreement and the other
Loan Documents for the performance of such  obligations,  (iii) the Borrower and
the Credit  Parties shall  continue to deal solely and directly with such Lender
in  connection  with  such  Lender's  rights  and  obligations  under  the  Loan
Documents,  (iv) the  Borrower  shall  not at any time be  obligated  to pay any
participant in any interest of any Lender hereunder any sum in excess of the sum
which the Borrower would have been obligated to pay to such Lender in respect of
such  interest had such Lender not sold such  participation,  and (v) the voting
rights of any holder of any participation  shall be limited to decisions that in
accordance with Section 11.1 require the consent of all of the Lenders.

          (d) Subject to subsection (e) below, any Lender may at any time assign
all or any portion of its rights under any Loan Document to any Federal  Reserve
Bank.

          (e) Except to the extent of any assignment  pursuant to subsection (b)
above,  no Lender  shall be  relieved of any of its  obligations  under the Loan
Documents as a result of any assignment of or granting of participations in, all
or any part of its rights and obligations under the Loan Documents.

     11.6. COUNTERPARTS; INTEGRATION.

          Each Loan  Document  (other  than the Notes) may be executed by one or
more of the parties  thereto on any number of separate  counterparts  and all of
said counterparts  taken together shall be deemed to constitute one and the same
document.  It shall not be  necessary  in making  proof of any Loan  Document to
produce  or  account  for more  than one  counterpart  signed by the party to be
charged.  Delivery of an executed  counterpart  of a signature  page of any Loan
Document by  facsimile  shall be  effective  as delivery of a manually  executed
counterpart  of such Loan Document.  The Loan Documents and any separate  letter
agreements  between the  Borrower and a Credit Party with respect to fees embody
the entire  agreement  and  understanding  among the Loan Parties and the Credit
Parties  with  respect to the subject  matter  thereof and  supersede  all prior
agreements and understandings among the Loan Parties and the Credit Parties with
respect to the subject matter thereof.

                                      -84-

     11.7. SEVERABILITY.

          Every provision of the Loan Documents is intended to be severable, and
if any term or provision thereof shall be invalid,  illegal or unenforceable for
any  reason,  the  validity,   legality  and  enforceability  of  the  remaining
provisions  thereof  shall  not  be  affected  or  impaired  thereby,   and  any
invalidity,  illegality or unenforceability in any jurisdiction shall not affect
the validity,  legality or  enforceability  of any such term or provision in any
other jurisdiction.

     11.8. GOVERNING LAW.

          THE LOAN  DOCUMENTS  AND THE RIGHTS  AND  OBLIGATIONS  OF THE  PARTIES
THEREUNDER  SHALL BE GOVERNED BY, AND  CONSTRUED AND  INTERPRETED  IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK.

     11.9. JURISDICTION; SERVICE OF PROCESS.

          Each  party  to a Loan  Document  hereby  irrevocably  submits  to the
nonexclusive  jurisdiction of any New York State or Federal court sitting in the
City of New York over any suit, action or proceeding  arising out of or relating
to the Loan Documents.  Each party to a Loan Document hereby irrevocably waives,
to the fullest extent permitted or not prohibited by law, any objection which it
may now or hereafter have to the laying of the venue of any such suit, action or
proceeding  brought in such a court and any claim that any such suit,  action or
proceeding  brought in such a court has been brought in an  inconvenient  forum.
Each Loan Party hereby agrees that a final judgment in any such suit,  action or
proceeding  brought in such a court,  after all  appropriate  appeals,  shall be
conclusive  and binding  upon it 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 a Credit Party may otherwise have to bring
any action or proceeding  relating to Loan Documents against the Borrower or its
properties  in the courts of any  jurisdiction.  Each  party to a Loan  Document
hereby  irrevocably  consents to service of process in the manner  provided  for
notices in Section 11.2.  Nothing in this Agreement will affect the right of any
party to a Loan Document to serve process in any other manner permitted by law.

     11.10. WAIVER OF TRIAL BY JURY.

          EACH PARTY HERETO HEREBY WAIVES,  TO THE FULLEST  EXTENT  PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING
DIRECTLY OR  INDIRECTLY  ARISING OUT OF OR  RELATING  TO THIS  AGREEMENT  OR THE
TRANSACTIONS  CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,  TORT OR ANY OTHER
THEORY).  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 BY, AMONG OTHER THINGS,  THE MUTUAL WAIVERS
AND CERTIFICATIONS IN THIS SECTION.

     11.11. SAVINGS CLAUSE.

          This   Agreement  is  intended   solely  as  an   amendment   of,  and
contemporaneous  restatement  of, the terms and  conditions  of the Existing ACE
Credit  Agreement and the Notes delivered  pursuant hereto are intended to amend
and restate the notes issued under the Existing ACE Credit Agreement and neither
this  Agreement or the Notes is intended  and neither  should be construed as in
any way  extinguishing  or terminating  the Existing ACE Credit  Agreement.  The
Existing Borrower Security Agreement and the Existing  Subsidiary  Guaranty,  to
the extent  provided in the Borrower  Pledge  Agreement  (Bank),  the Subsidiary
Guaranty and the Restricted  Subsidiary Security Agreement (Bank) remain in full
force and effect and continue to secure the  obligations  of the Loan Parties as
set forth therein.

     11.12. CONFIDENTIALITY.

          Each of the Lenders and the Administrative  Agent agrees (on behalf of
itself  and  each  of  its  affiliates,   directors,   officers,  employees  and
representatives)  to  use  reasonable  precautions  to  keep  confidential,   in
accordance with their customary procedures for handling confidential information
of the same nature, all non-public information supplied by Arch, the Borrower or
any of their  respective  Subsidiaries  pursuant to this Agreement  which (a) is
identified  by such  Person  as  being  confidential  at the  time  the  same is
delivered to such Lender or the  Administrative  Agent,  or (b)  constitutes any
financial  statement,  financial  projections or forecasts,  budget,  compliance
certificate,  audit  report,  management  letter or  accountants'  certification
delivered hereunder (collectively,  the "CONFIDENTIAL  INFORMATION"),  provided,
however,  that nothing  herein shall limit the  disclosure  of any  Confidential
Information (i) to the extent required by statute,  rule, regulation or judicial
process,  (ii) on a confidential  basis, to counsel to any of the Lenders or the
Administrative Agent, (iii) to bank examiners,  auditors or accountants, and any
analogous  counterpart thereof, (iv) to the Administrative Agent or the Lenders,
(v) in connection with any litigation to which any one or more of the Lenders or
the Administrative Agent is a party, provided that if practicable to do so under
the  circumstances,  Arch or the  Borrower,  as the case may be, is given  prior
notice of, and an  opportunity to contest,  the production of such  Confidential
Information  (which such notice and  opportunity  shall be reasonable  under the
circumstances),  (vi) to any assignee or participant (or prospective assignee or
participant) so long as such assignee or participant (or prospective assignee or
participant)   agrees  in   writing  to  keep  such   Confidential   Information
confidential on  substantially  the same basis as set forth in this Section,  or
(vii) to affiliates of the Administrative Agent or each Lender.  Notwithstanding
the provisions of clause (vii) above,  neither the Administrative  Agent nor any
Lender shall disclose any such Confidential Information to any of its respective
affiliates,  directors,  officers,  employees or  representatives  except to the
extent  that it or they have a need to know  such  Confidential  Information  in
connection  with the  structuring  or  administration  of the  Loans or any Loan
Document,  any  assignment or  participation  thereof or  activities  incidental
thereto.

     11.13. RELEASE OF BENBOW ASSETS.

          By  executing  this  Agreement,  each  of the  Credit  Parties  hereby
authorizes  BNY as the  Administrative  Agent under (i) the Existing  Subsidiary
Guaranty  to release  the Liens  granted by  Westlink  thereunder  in the Benbow
Assets, (ii) the Existing Parent Security Agreement to release the Liens granted
by the Parent  thereunder in the Benbow Assets,  and (iii) the Existing Borrower
Security  Agreement  the Liens  granted by ACE in its Stock in  Westlink  II (if
any).  Nothing  herein shall  affect the right of the Credit  Parties to require

                                      -86-
<PAGE>

Benbow  Investments  to  become  a  Subsidiary  Guarantor  and a  party  to  the
Unrestricted  Subsidiary  Security  Agreement (Bank) on the Existing Arch Senior

of the  adjustments  and  prorations  to be made  pursuant to this  ss.2(d)(ii),
including any adjustments  and prorations made at Closing,  together with a copy
of any  working  papers  relating  to such  Closing  Certificate  and such other
supporting  evidence  as the  Sellers  may  reasonably  request.  If the Sellers
conclude  that  the  Closing   Certificate  does  not  accurately   reflect  the
adjustments and prorations to be made pursuant to this ss.2(d)(ii),  the Sellers
shall, within thirty (30) days after receipt thereof, provide to the Buyer their
written  statement of any  discrepancies  believed to exist. The Sellers and the
Buyer shall attempt  jointly to resolve the  discrepancies  within  fifteen (15)
days after receipt of the Sellers' discrepancy statement,  which resolution,  if

                                       10
<PAGE>

achieved, shall be binding upon all parties to this Agreement and not subject to
dispute or review. If the Sellers and the Buyer cannot resolve the discrepancies
within  such  fifteen  (15) day  period,  the Buyer and  Sellers  shall  jointly
designate a nationally known  independent  public accounting firm to be retained
to  review  the  Closing  Certificate  together  with the  Sellers'  discrepancy
statement  and  any  other  relevant  documents.  The  cost  of  retaining  such
accounting firm shall be borne by the party found to be more in error. Such firm
shall report its  conclusions  as to adjustments  pursuant to this  ss.2(d)(ii),
which shall be conclusive and not subject to dispute or review. Once the Closing
Certificate  has been  approved  by both  parties,  if the Buyer shall have been
determined to owe an amount to the Sellers, the Buyer shall within five (5) days
of the date the Closing  Certificate  shall have been approved by both the Buyer
and the Sellers pay such amount thereof to the Sellers,  or if the Sellers shall
have been  determined  to owe an amount to the Buyer,  the Sellers  shall within
five (5) days of the date the Closing  Certificate  shall have been  approved by
both the Buyer and the Sellers pay such amount thereof to the Buyer.

               (iii) In addition to the  adjustments  to the Base Purchase Price
made pursuant to Section  2(d)(ii) above, if any particular Site is, on the date
which is five business  days prior to the Closing Date,  subject to any Security
Interest or Defect, then, at the Buyer's election, such Site shall be dealt with
as described in this clause (iii):

                    (A) the  Buyer  may  notify  the  Sellers  that it wishes to
postpone the purchase of any such Site until the Second  Closing  Date, in which
event the Base Purchase  Price  payable at the Initial  Closing shall be reduced
for each such Defect  Site by an amount  equal to the greater of (i) the product
of 11.8  multiplied by the  Annualized  Operating Cash Flow for each Defect Site
which the Buyer elects not to purchase at the Initial  Closing or (ii) $100,000;
or

                    (B) the  Buyer  may  notify  the  Sellers  that it wishes to
include such Defect Site in the  Acquired  Assets on the Initial  Closing  Date,
subject to the Sellers'  indemnification  for the Security Interest or Defect as
provided in ss.8(g).  If the Buyer elects to have such Defect Sites  included in
the  Acquired  Assets,  the Buyer  shall  notify the Sellers not less than eight
business days prior to the Initial Closing Date, and the Sellers shall thereupon
indemnify the Buyer in respect of the identified  Defects as provided in Section
8(g) unless the Sellers  notify the Buyer in writing  prior to the date which is
five  business  days  before  the  Initial  Closing  Date  that they will not so
indemnify the Buyer. If the Sellers elect not to indemnify the Buyer,  the Buyer
may  then  elect  either  to  accept  the  Defect  Sites  without  the  Sellers'
indemnification under Section 8(g) or postpone the purchase of such Defect Sites
until the Second  Closing,  in which case the Base Purchase Price at the Initial
Closing Date shall be reduced as provided in clause (a) of this subsection.

               (iv) On the Second  Closing  Date,  the Buyer shall  purchase any
Sites which were  Defect  Sites as of the  Initial  Closing  Date if the Defects
attributable   to  such  Sites  have  been  cured  to  the  Buyer's   reasonable
satisfaction  not later than the five business days prior to the Second  Closing
Date. Notwithstanding any other provision contained in this Agreement, the Buyer
shall not be obligated to acquire any Sites at the Initial Closing or the Second
Closing  unless  any  Defects  for such  Site  have  been  cured to the  Buyer's
reasonable satisfaction. The purchase price in respect of each Site purchased at

                                       11
<PAGE>

the Second  Closing will be equal to the Base Purchase  Price  reduction made in
respect of such Site at the Initial Closing.

               (v) If on the  date  which  is five  business  days  prior to the
Second  Closing  Date any  Defect  Site  continues  to be  subject to a Security
Interest or an uncured Defect, then, at the Buyer's election:

                    (A) the  Buyer  may  notify  the  Sellers  that it wishes to
exclude such Site from the Acquired  Assets,  in which event such Site shall not
be transferred to the Buyer; or

                    (B) the  Buyer  may  notify  the  Sellers  that it wishes to
include  such Defect Site in the  Acquired  Assets on the Second  Closing  Date,
subject to the Sellers'  indemnifications for the Security Interest or Defect as
provided in ss.8(g).  If the Buyer elects to have such Defect Sites  included in
the  Acquired  Assets,  the Buyer  shall  notify the Sellers not less than eight
business days prior to the Second Closing Date, and the Sellers shall  thereupon
indemnify the Buyer in respect of the identified  Defects as provided in ss.8(g)
unless the Sellers  notify the Buyer in writing  prior to the date which is five
business  days prior to the Second  Closing Date that they will not so indemnify
the Buyer.  If the Sellers elect not to indemnify the Buyer,  the Buyer may then
elect  either to accept the Defect Sites  without the  Sellers'  indemnification
under ss.8(g) or not to acquire such Defect Sites.

               The Parties  shall have no further  obligations  to each other in
respect  of Defect  Sites  which the Buyer  elects  not to acquire on the Second
Closing Date. No further  adjustment to the Base Purchase  Price (in addition to
the adjustment to the Base Purchase Price effected at the Initial Closing) shall
be made in respect of Defect  Sites which the Buyer elects not to acquire at the
Second Closing.

          (e) THE CLOSING. The closing of the transactions  contemplated by this
Agreement  (the  "Closing")  shall  take  place on June 30,  1998 (the  "Initial
Closing  Date") at the  offices  of  Thompson,  Hine & Flory,  3900 Key  Center,
Cleveland,  Ohio  44114,  commencing  at 9:00  a.m.  local  time,  provided  the
conditions  identified  in  Section 7 below  have  been  satisfied  (except  for
conditions  to be  satisfied  at the  Closing) on or before such date.  A second
Closing will be held on the date (the "Second Closing Date") which is sixty days
after the Initial Closing Date in respect of Sites which have uncured Defects or
Security  Interests as of the Initial  Closing Date. The "Initial  Closing Date"
and the  "Second  Closing  Date"  are  collectively  referred  to  herein as the
"Closing Date".

          (f)  DELIVERIES AT THE CLOSING.  At the Closing,  (i) the Sellers will
deliver to the Buyer the various deeds, assignments,  certificates,  instruments
and documents  referred to in ss.7(a) below;  (ii) the Buyer will deliver to the
Sellers the various  certificates,  instruments,  and  documents  referred to in
ss.7(b) below; (iii) the Sellers will execute, acknowledge (if appropriate), and
deliver  to the  Buyer  such  instruments  of sale,  transfer,  conveyance,  and
assignment as the Buyer and its counsel reasonably may request (including a deed
for each Owned Site with statutory warranties regarding  encumbrances created by
the  relevant  Seller);  (iv) the Buyer and the Sellers will execute and deliver

                                       12
<PAGE>

the Master  Tower  Space  Lease and Site  Subleases  substantially  in the forms
annexed hereto;  (v) the Buyer will execute,  acknowledge (if appropriate),  and
deliver to the Sellers such  instruments  of assumption as the Sellers and their
counsel  reasonably may request;  and (vi) the Buyer will deliver to the Sellers
the consideration specified in ss.2(d) above.

          (g) ALLOCATION.  The Parties agree to allocate the Purchase Price (and
all other  capitalizable  costs)  among the  Acquired  Assets  for all  purposes
(including  financial,  accounting  and tax  purposes)  in  accordance  with the
allocation schedule attached hereto as Exhibit G. The Sellers shall allocate the
Purchase Price among the Sellers as directed by Arch Communications Group, Inc.

     3. REPRESENTATIONS AND WARRANTIES OF THE SELLERS. The Sellers represent and
warrant to the Buyer that the statements  contained in this ss.3 are correct and
complete as of the date of this Agreement and will be correct and complete as of
the  Closing  Date (as  though  made then and as though  the  Closing  Date were
substituted for the date of this Agreement  throughout this ss.3), except as set
forth in the disclosure  schedule  accompanying  this Agreement and initialed by
the  Parties  (the  "Disclosure  Schedule").  The  Disclosure  Schedule  will be
arranged in  paragraphs  corresponding  to the lettered and numbered  paragraphs
contained  in this ss.3.  The  Sellers  make no  representations  or  warranties
concerning the Acquired  Assets or the Arch Towers  Business except as set forth
in this ss.3.

          (a) ORGANIZATION OF THE SELLERS.  Each of the Sellers is a corporation
duly  organized,  validly  existing,  and in good standing under the laws of the
jurisdiction  of its  incorporation  as indicated on the signature pages hereof.
Each of the Sellers has full power to carry on its business as now conducted and
is  qualified  to do business  as a foreign  entity in each  jurisdiction  where
failure to so  qualify  would have a  material  adverse  affect on the  Acquired
Assets.

          (b)  AUTHORIZATION OF TRANSACTION.  Each of the Sellers has full power
and authority  (including  full  corporate  power and  authority) to execute and
deliver  this  Agreement  and to  perform  its  obligations  hereunder.  Without
limiting the generality of the foregoing,  the board of directors of each of the
Sellers has duly  authorized the execution,  delivery,  and  performance of this
Agreement by the respective  Seller.  This Agreement  constitutes  the valid and
legally  binding  obligation of each of the Sellers,  enforceable  in accordance
with its terms and  conditions,  except as such  enforcement  may be  limited by
applicable bankruptcy,  insolvency,  reorganization or similar laws from time to
time in effect affecting  creditors' rights generally and by legal and equitable
limitations  on the  availability  of  specific  remedies  (the  "Enforceability
Exceptions").

          (c)  NONCONTRAVENTION.  Neither the execution and the delivery of this
Agreement,  nor  the  consummation  of  the  transactions   contemplated  hereby
(including the assignments and assumptions  referred to in ss.2 above), will (i)
violate any  constitution,  statute,  regulation,  rule,  injunction,  judgment,
order,  decree,   ruling,  charge,  or  other  restriction  of  any  government,
governmental  agency,  or court to which any of the  Sellers  is  subject or any
provision  of the  charter or bylaws of any of the  Sellers or (ii) except as to
required notice described in Section 3(c) of the Disclosure  Schedule,  conflict
with,  result  in a  breach  of,  constitute  a  default  under,  result  in the

                                       13
<PAGE>

acceleration of, create in any party the right to accelerate, terminate, modify,
or cancel, or require any notice under any agreement,  contract, lease, license,
instrument,  or other  arrangement  to which any of the Sellers is a party or by
which it is bound or to which any of its  assets is  subject  (or  result in the
imposition of any Security  Interest  upon any of its assets),  except where the
violation, conflict, breach, default, acceleration,  termination,  modification,
cancellation or failure to give notice, would not have a material adverse effect
on any of the Acquired Assets or on the ability of the Parties to consummate the
transactions contemplated by this Agreement. Except as set forth in Section 3(c)
of the  Disclosure  Schedule,  none of the Sellers  needs to give any notice to,
make any filing with, or obtain any authorization,  consent,  or approval of any
government  or  governmental  agency  or of any  private  party in order for the
Parties to consummate the transactions contemplated by this Agreement (including
the assignments and assumptions referred to in ss.2 above).

          (d) BROKERS'  FEES. The Sellers have no liability or obligation to pay
any fees or  commissions  to any broker,  finder,  or agent with  respect to the
transactions  contemplated  by this  Agreement  for which the Buyer could become
liable or  obligated.  The  Sellers  have  engaged  the  services  of  Daniels &
Associates,  L. P. as an agent of the Sellers in connection with this Agreement,
and the Sellers will be solely  responsible for any fees or commissions  payable
to such agent.

          (e)  FINANCIAL  INFORMATION.  The financial  information  set forth in
Exhibit H is the only financial information provided by the Sellers to the Buyer
in connection with this Agreement. The information in Exhibit H1 under the items
entitled  "Third  Party Rent  Revenue"  and  "Annual  Land Lease  Expenses"  are
Sellers'  estimates  for such items for the twelve month period ending March 31,
1998,  based on actual rent  revenues  from third  parties and actual land lease
expenses  during the month of March,  1998.  Exhibit  H2 also sets forth  actual
Third  Party Rent  Revenue  for the Sites for the months of June,  1997  through
March, 1998. The information in Exhibit H concerning Arch Rent Revenue correctly
reflects  the annual rent which  Sellers  will pay to the Buyer  pursuant to the
Master Tower Space Lease during the first twelve  months after the Closing Date,
subject  to  adjustments  permitted  under the Master  Tower  Space  Lease.  The
"Squatters  Rent Increase"  reflected in Exhibit H1, and expenses of maintenance
and  utilities,  are the  Sellers'  estimates;  the  Sellers do not  warrant the
correctness or reasonableness of such estimates.

          (f) EVENTS SINCE MARCH 31, 1998.  Since March 31, 1998,  there has not
been any material  adverse change in the financial  condition of the Arch Towers
Business  taken as a whole or any material  adverse  change in the  condition or
operation of any tower. Without limiting the generality of the foregoing,  since
that date none of the Sellers has engaged in any practice,  taken any action, or
entered  into any  transaction  outside the  Ordinary  Course of  Business  with
respect to the Arch Towers  Business  except in connection  with the sale of the
Arch Towers Business.

          (g)  LEGAL  COMPLIANCE.  Each of the  Sellers  has  complied  with all
applicable  Laws,  except  where the failure to comply would not have a material
adverse effect upon the financial  condition of any particular Site. The Sellers
have  received no notice to the effect that any Site is not in  compliance  with
applicable Laws.

                                       14
<PAGE>

          (h) TAX MATTERS.  Sellers have filed with the appropriate governmental
agencies all tax returns and tax reports  pertaining to excise taxes,  sales and
use taxes,  payroll taxes,  real property taxes and assessments and tangible and
intangible  personal property taxes required to be filed by them relating to the
Owned Sites,  the Leased  Sites and towers and  operation  thereof  ("Applicable
Taxes"),  and all  taxes,  interest  and  penalties  shown or  claimed to be due
thereon  have  been  paid.  Sellers  do not have any  liability,  contingent  or
otherwise,  for any Applicable Taxes or any interest or penalties thereon except
to the extent  disclosed  in Section  3(i) of the  Disclosure  Schedule.  To the
Knowledge of the Sellers,  the consummation of the transactions  contemplated by
this Agreement  will not result in any transferee tax liability to Buyer,  other
than possible sales taxes on sales of personal property included in the Acquired
Assets.  None of the Sellers has waived any statute of limitations in respect of
Applicable  Taxes  or  agreed  to any  extension  of  time  with  respect  to an
Applicable Tax assessment or deficiency.

          (i) PROPERTY.

               (i)  Sellers do not have any  interest  in any real  property  in
connection with the operation of the towers other than as described on Exhibit A
and Exhibit B. Each Seller is, or will be, at the time of Closing, in possession
of each of its Sites. Each Seller has, or will have at the time of Closing,  (A)
good,  marketable,  and  fee  simple  title  to its  Owned  Sites  and  all  the
improvements,  (B) good and valid leasehold  estates or good and valid easements
as to its  Leased  Sites,  (C) good and  valid  easement  rights  providing  all
necessary  access and  utilities to and from the  improvements  and the Sites to
public roads, and (D) good and marketable  legal title to all personal  property
included  in the  Acquired  Assets,  in each  case,  free  and  clear of all (i)
Security Interests except for (i) Security Interests described in the Disclosure
Schedule,  which will be released  and  discharged  prior to the  Closing,  (ii)
Permitted Encumbrances and (iii) Defects which, if the affected Site is conveyed
to the Buyer  will be  discharged  or cured  prior to the  Closing  or will be a
matter for which the Buyer is indemnified pursuant to ss.8(g).

               (ii) No Seller has voluntarily granted any, is not a party to any
agreement  providing  for,  and no  Seller  has  any  knowledge  of,  easements,
conditions,  reservations,  covenants,  restrictions, leases, subleases, rights,
options or any other matters that would  adversely  affect the use of any of the
towers and the Sites for the same purposes and uses as the towers and Sites have
been used by such Seller, except for (i) Security Interests described in ss.3(i)
of the Disclosure  Schedule,  which will be released and discharged prior to the
Closing,  (ii) Permitted  Encumbrances  and (iii) Defects which, if the affected
Site is conveyed to the Buyer,  will be discharged or cured prior to the Closing
or will be a matter for which the Buyer is indemnified pursuant to ss.8(g).

               (iii)  To the  best  of each  Seller's  knowledge,  there  are no
improvements planned by any public authority any part of the cost of which might
be assessed against such Seller.

               (iv) To each Seller's knowledge, with respect to its Sites, there
are no (A)  applications,  ordinances,  petitions,  resolutions or other matters

                                       15
<PAGE>

pending  before any  governmental  agency having  jurisdiction  to act on zoning
changes that would  prohibit or make  nonconforming  the use of any of the Sites
for the operation of the towers;  or (B) pending or threatened  condemnation  or
eminent domain proceedings, or proposed sale in lieu thereof.

               (v) To each Seller's knowledge (except as reported by the Buyer),
the  improvements,  including  the  towers,  are in good  condition  and repair,
ordinary  wear and tear  excepted,  and do not have any  structural  or material
defects except as described on Section 3(j) of the Disclosure Schedule.

               (vi) Exhibit A lists all of the Leased Sites,  and identifies the
lease date and the lessor  thereunder  and the  current  monthly  rental paid by
Sellers. To the extent that written leases,  management  agreements or easements
exist and are in the  Sellers'  possession,  the Sellers  have  delivered to the
Buyer correct and complete  copies  thereof.  The Sellers do not possess written
documents  for all of Leased  Sites,  and the leases,  management  agreements or
easements for some locations have expired,  as indicated in Exhibit A; provided,
however,  the Sellers  will use their  commercially  reasonable  best efforts to
remove these  Defects prior to Closing.  To the Knowledge of the Sellers,  there
are no disputes  with the lessor or sublessor  of any of the leases,  management
agreements  or  easements  listed on Exhibit A except as described in ss.3(i) of
the Disclosure  Schedule or where such dispute would not have a material adverse
effect on the financial condition of any particular tower; provided however, the
Sellers  will use their  commercially  reasonable  best  efforts to remove these
Defects  prior to Closing.  Each lease or sublease  listed on Exhibit A which is
written  and has not expired by its terms (as  indicated  on Exhibit A) is valid
and in  full  force  and  effect,  unless  otherwise  noted  in  ss.3(i)  of the
Disclosure  Schedule.  Any lease or  sublease  listed on  Exhibit A which is not
written and in full force and effect on the Closing Date will be  considered  to
have a Defect,  and may be dealt with as  provided  in  ss.2(d)(iii).  Except as
described on 3(i) of the Disclosure  Schedule,  the leases are freely assignable
to the Buyer  without  the  consent of any  landlord,  tenant or third party and
there  are no  defaults  on the part of  Sellers  or,  to the  Knowledge  of the
Sellers, their landlords.

          (j) INTELLECTUAL PROPERTY. None of the Sellers owns or has an interest
in any patent or registration  or any pending patent  application or application
for registration related to the Acquired Assets or the Arch Towers Business.

          (k)  GOVERNMENTAL  AUTHORIZATIONS.  To the  knowledge  of the Sellers,
there are no  licenses or other  governmental  authorizations  required  for the
operation of the Acquired  Assets which the Sellers do not hold;  Sellers are in
compliance therewith;  and such licenses and governmental  authorizations are in
full force and effect.  To the extent  required by  regulations  of the FCC, the
towers owned by the Sellers on the Sites are registered with the FCC. The towers
are in compliance with all applicable FAA and FCC rules and regulations.

          (l)  TENANT  LEASES  AND OTHER  CONTRACTS.  Exhibit H3 lists all tower
space leases,  tower license  agreements and similar  agreements (and the rental
and  security  deposits  relating  thereto)  pursuant to which the Sellers  have
leased space on any of the communications towers included in the Acquired Assets
to third parties (each a "Tower Space Lease"). In addition,  except as set forth
in Section  3(l) of the  Disclosure  Schedule,  there are no other  tower  space

                                       16
<PAGE>

leases,  licenses or similar occupancy agreements to which any Seller is a party
related to the operation of the Arch Towers Business. To the extent that written
documents  constituting  Tower  Space  Leases  exist  and  are in  the  Sellers'
possession,  the Sellers have delivered to the Buyer a correct and complete copy
of each such  document  (as  amended to date)  listed in Exhibit  H3. Each Tower
Space Lease listed in Exhibit H3 which has not expired by its terms is valid and
in full force and effect and there are no material  defaults  pending  caused by
the Sellers or their tenants  (other than late payment  defaults by such tenants
the aggregate amount of which as of March, 1998 is set forth in Exhibit H3). The
Sellers do not possess  written  documents for all the Tower Space Leases listed
in Exhibit H3, and some of the written documents so listed have expired.  One of
the Sellers is the sole owner of the  landlord's or  licensor's  interest in the
Tower Space Leases,  and the Sellers'  interest in the Tower Space  Leases,  are
fully  assignable  to the Buyer without the consent or approval of any landlord,
tenant or other third  party.  As of the Closing  Date,  no rents due under,  or
other  interest in, any of the Tower Space Leases will have been assigned to any
other party other than the Buyer or otherwise  pledged or encumbered in any way.
Except as set forth in Exhibit H3, the Sellers have not received any notice from
any tenant or licensee  under a Tower Space Lease of any impending  cancellation
or breach of its Tower  Space  Lease or of any  termination  of its Tower  Space
Lease in advance of the scheduled  expiration date.  Exhibit H3 and Section 3(l)
of the Disclosure  Schedule will be updated as of a date within 15 days prior to
the Closing Date.

          (m) LITIGATION.  None of the Sellers (i) is subject to any outstanding
injunction, judgment, order, decree, ruling, or charge or (ii) is a party to any
action, suit, proceeding,  hearing, or investigation of, in, or before any court
or  quasi-judicial  or administrative  agency of any federal,  state,  local, or
foreign jurisdiction,  where the injunction,  judgment,  order, decree,  ruling,
action,  suit,  proceeding,  hearing,  or investigation  affects the Arch Towers
Business or the Acquired Assets.

          (n) ENVIRONMENTAL, HEALTH, AND SAFETY MATTERS.

               (i)  To  the  Knowledge  of  the  Sellers,  the  Sellers  are  in
compliance with Environmental, Health, and Safety Requirements.

               (ii) The Sellers have not received any written notice,  report or
other  information  regarding any actual or alleged  violation of Environmental,
Health,  and Safety  Requirements,  or any liabilities or potential  liabilities
(whether accrued, absolute,  contingent,  unliquidated or otherwise),  including
any investigatory,  remedial or corrective obligations,  relating to the Sellers
or their facilities included in the Acquired Assets arising under Environmental,
Health, and Safety Requirements.

               (iii) The Sellers are not aware of any underground  storage tanks
on any of the land  included  in the  Acquired  Assets  except as  described  in
ss.3(n) of the Disclosure  Schedule.  To the extent Sellers own any  underground
storage tanks,  Sellers are in compliance  with all laws,  rules and regulations
relating thereto.

               (iv)  This   Section  3(n)   contains  the  sole  and   exclusive
representations and warranties of the Sellers with respect to any environmental,
health, or safety matters,  including  without  limitation any arising under any
Environmental, Health, and Safety Requirements.

                                       17
<PAGE>

          (o) CERTAIN BUSINESS  RELATIONSHIPS  WITH SELLERS.  After the Closing,
the sole  contractual  relationships  between  the  Sellers  and the Buyer  with
respect to the Acquired  Assets will be this  Agreement,  the Master Tower Space
Lease, the Site Subleases and the Site Leases.

          (p)   SUFFICIENCY   OF  ASSETS.   The  Acquired   Assets  include  all
Site-related  equipment and real property  rights used by the Sellers to operate
the Arch  Towers  Business,  except  for any  generators  that are  specifically
excluded from the  definition of "Acquired  Assets" which would be necessary for
the operations of the Arch Towers Business. The Acquired Assets do not, however,
include any personnel, computers, technical expertise, vehicles, maintenance and
repair equipment or other non-Site-specific  assets required to operate the Arch
Towers Business.

          (q) NO CONDEMNATION. To the knowledge of the Sellers none of the Owned
Sites is the subject of any pending or proposed condemnation  proceedings by any
public authority. The Sellers have not received any notice from the owner of any
Leased  Site to the  effect  that such Site is the  subject  of any  pending  or
proposed condemnation proceedings by any public authority.

          (r) CONTRACTS.  Section 3(r) of the Disclosure Schedule  constitutes a
complete and accurate list of all material  contracts  (other than (i) leases or
other  agreements  pursuant to which the Sellers hold real property  included in
the Acquired Assets and (ii) Tower Space Leases) (the  "Contracts")  relating to
the Acquired  Assets or the operation of the Sites to which Seller is a party or
by which it is bound. The Contracts are in full force and effect.  Except as set
forth in Section  3(r) of the  Disclosure  Schedule,  there has been no material
default by the Sellers or, to the Sellers' knowledge, by the other party, and no
event has  occurred  or failed to occur  which with the  giving of  notice,  the
passage of time, or both,  would  constitute a material  default by the Sellers,
or,  to the  best of their  knowledge,  by the  other  party,  under  any of the
Contracts.  Except as set forth in ss.3(l) of the  Disclosure  Schedule,  to the
Sellers'  knowledge,   none  of  the  Contracts  is  subject  to  any  impending
cancellation  or breach  that will  result in a  substantial  loss or  otherwise
materially and adversely affect the Sites or the Acquired Assets.

          (s)  DISCLAIMER OF OTHER  REPRESENTATIONS  AND  WARRANTIES.  Except as
expressly  set forth in this  Section 3, the Sellers make no  representation  or
warranty,  express or implied,  at law or in equity,  in respect of any of their
assets  (including,  without  limitation,  the Acquired Assets),  liabilities or
operations,  including,  without limitation,  with respect to merchantability or
fitness  for any  particular  purpose,  and any such  other  representations  or
warranties are hereby expressly  disclaimed.  The Buyer hereby  acknowledges and
agrees that, except to the extent  specifically set forth in this Section 3, the
Buyer is purchasing the Acquired Assets on an "as-is,  where-is" basis.  Without
limiting the generality of the foregoing,  the Sellers make no representation or
warranty  regarding any assets other than the Acquired Assets, and none shall be
implied at law or in equity.

          (t) INFORMATION  CONCERNING THE REDDING,  CALIFORNIA SITE. Information
provided by the Sellers in respect of the Redding,  California  Site is based on
information  provided  to the  Sellers by the  current  owners of the Site.  The
Sellers do not represent or warrant the  correctness  of such  information.  The
Sellers will represent and warrant such information at the Closing.

               (i) The Sellers will give any notices to third parties reasonably
requested by the Buyer;  without  limiting the generality of the foregoing,  the
Sellers  will use their  commercially  reasonable  best efforts  (including  the

with the matters referred to in ss.3(c) and ss.4(c) above.  Without limiting the
generality of the foregoing,  each of the Parties will file any Notification and

interfere  with the normal  business  operations  of the  Sellers,  or  Sellers'
activities undertaken to perform their obligations under this Agreement,  to all
premises,  properties,   personnel,  books,  records  (including  tax  records),
contracts, surveys, title reports and environmental and engineering reports, and
documents of or pertaining to that portion of the Arch Towers  Business owned by
each of the  Sellers.  The  Buyer  will keep  confidential  and hold as such any

                                       20
<PAGE>

exchange) or disclose any  nonpublic  information  regarding any of the Acquired
Assets.

          (g) TITLE; SURVEYS; CORRECTION OF DEFECTS.

               (i) The Buyer shall use its commercially  reasonable best efforts
to order all title and surveys  within 10 business days of the date hereof.  The
Buyer  shall  use  its  commercially   reasonable  best  efforts  to  order  all
environmental  assessments within 15 business days of the date hereof. The Buyer
will provide to the Sellers copies of all letters  requesting  titles,  surveys,
environmental  assessments and zoning compliance letters as such request letters
are issued.

               (ii) If the Buyer  believes a Site has a Defect  which  makes the
Site  subject to Section  2(d)(iii),  it shall  notify the  Sellers  within five
business  days after  discovering  the Defect.  (The Buyer  hereby  notifies the
Sellers  that the items  disclosed in Exhibit A, B and C and Section 3(i) of the
Disclosure Schedule which constitute Defects are subject to Section 2(d)(iii).).

               (iii)  Sellers  shall  use  their  commercially  reasonable  best
efforts to correct all Defects,  whether or not such Defect is shown on Exhibits
A, B and C or the Disclosure Schedule,  prior to the Initial Closing Date or, if
unable to do so by the Initial  Closing  Date, by the Second  Closing Date.  The
Sellers shall,  if the  circumstances  require,  expend up to $5,000 per Site to
cure or correct Defects if it is reasonably  expected that such amount will cure
the Defect applicable to such Site to the reasonable  satisfaction of the Buyer.
The Sellers may, but shall not be required hereby to, expend more than $5,000 to
cure Defects at any Site.

               (iv) The Sellers  shall  promptly  notify the Buyer in writing of
each  Defect  which the  Sellers  believe  has been  cured,  and the Buyer shall
promptly  notify the  Sellers  if it agrees  that a Defect has been cured to its
satisfaction.  The Buyer and the Sellers shall work  cooperatively to coordinate
the Defect  notification  and cure  process so that cures  sought by the Sellers
will be acceptable to the Buyer if effected.

               (v) Not less than five business days prior to the Initial Closing
Date the Buyer and the Sellers shall compile lists of Sites for which no Defects
exist,  and Sites for which Defects  continue to exist,  and shall identify such
Sites  with  uncured   Defects  (if  any)  which  the  Buyer  elects  to  accept
notwithstanding  the Defect,  such of those Sites which the Buyer has elected to
accept for which the Sellers will indemnify the Buyer pursuant to ss.8(g),  such
of those Sites which the Buyer has elected to accept for which the Sellers  will
not indemnify the Buyer pursuant to ss.8(b), and (of the latter group) any Sites
which the Buyer will nonetheless purchase on the Initial Closing Date.

               (vi) Any Defect  Sites not  acquired  by the Buyer on the Initial
Closing Date shall be subject to the same notification/cure/acceptance/rejection
procedures described in clause (v) prior to the Second Closing Date.

                                       21
<PAGE>

               (vii) The Sellers shall use their  commercially  reasonable  best
efforts (but without the requirement of expending in excess of $100 per Site) to
obtain a  nondisturbance  agreement  with each  landlord of the Sites  listed on
Exhibit F-1 or to obtain a direct  lease  between the landlord and the Buyer for
the tower and transmitter space at each such Site.

          (h) If Sites representing  Annualized Operating Cash Flow in excess of
10% of the Annualized  Operating Cash Flow of all the Sites have uncured Defects
and the Buyer has  elected  not to  acquire  such  Sites  (or,  if the Buyer has
elected to acquire such Sites,  the Sellers have declined to indemnify the Buyer
pursuant to ss.8(g)  and the Buyer has  therefore  elected  not to acquire  such
Site) as of the date which is five  business  days prior to the Initial  Closing
Date, either Party may terminate this Agreement in accordance with ss.9.

          (i) The Sellers will use their reasonable best efforts,  and cooperate
with the Buyer, to obtain  extensions or new leases with respect to Leased Sites
for which current leases expire in calendar 1999.

     6. POST-CLOSING COVENANTS. The Parties agree as follows with respect to the
period following the Closing.

          (a) GENERAL.  In case at any time after the Closing any further action
is necessary or desirable to carry out the purposes of this  Agreement,  each of
the Parties will take such further action  (including the execution and delivery
of such further  instruments  and  documents) as the other Party  reasonably may
request,  all at the sole cost and expense of the  requesting  Party (unless the
requesting Party is entitled to indemnification  therefor under ss.8 below). The
Sellers  will  cooperate  with the Buyer,  at the Buyer's sole  expense,  to the
extent the Buyer needs assistance with or access to the Sellers' accountants and
books and records in  preparing,  verifying,  auditing,  reviewing or certifying
financial information.

          (b)  LITIGATION  SUPPORT.  In the  event  and for so long as any Party
actively is  contesting  or  defending  against any  action,  suit,  proceeding,
hearing,  investigation,  charge, complaint, claim, or demand in connection with
(i)  any  transaction  contemplated  under  this  Agreement  or (ii)  any  fact,
situation,   circumstance,   status,   condition,   activity,   practice,  plan,
occurrence,  event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving any of the Sellers, the other Party will cooperate
with the  contesting  or  defending  Party and its  counsel  in the  contest  or
defense, make available its personnel,  and provide such testimony and access to
its books and records as shall be  necessary in  connection  with the contest or
defense,  all at the sole cost and expense of the contesting or defending  Party
(unless  the  contesting  or  defending  Party is  entitled  to  indemnification
therefor  under ss.8  below).  This  provision  shall not  require  the  Buyer's
participation  in  litigation  between  the  Sellers  and any  person  which had
previously agreed to purchase the Acquired Assets.

          (c) TRANSITION.  The Sellers will not take any action that is designed
or intended to have the effect of  discouraging  any lessor,  licensor,  lessee,
licensee,  customer, supplier, or other business associate of any of the Sellers
from  maintaining  the same  business  relationships  with the  Buyer  after the
Closing as it maintained with the Sellers prior to the Closing.

                                       22
<PAGE>

          (d)  REPURCHASE  OPTIONS.  Sellers shall have the option to repurchase
portions of the Acquired Assets in forty quarterly  segments  commencing on June
30, 1998 and  continuing on each  September 30 1, December 31, March 31 and June
30  thereafter.  The  portion of the  Acquired  Assets  which is subject to such
purchase option on each of the forty dates (each an "option block") is described
in  Exhibit  I.  Exhibit I also sets forth the  portion  of the  Purchase  Price
allocable to each such portion of the Acquired Assets. The option price for each
option block is equal to the operating cash flow  (determined by multiplying the
Sites' cash flow for the month most  recently  ended as of the exercise  date by
12) for the Sites included in the option block multiplied by 28; provided,  that
in no event shall the option price be less than $250,000 for any one Site.  This
option may not be  assigned by the  Sellers  other than to persons  controlling,
controlled by or under common control with the Sellers. The Sellers may exercise
an option by, and only by, delivering  written notice of exercise of such option
no later than the exercise date. The Sellers may elect at any time, or from time
to time, to terminate the  exercisability of one or more of the quarterly option
segments.  If the Sellers  fail to  exercise a  quarterly  option on an exercise
date,  the option with respect to the next option group on Exhibit I shall lapse
and shall no longer be  exercisable.  The purchase price under each option shall
be paid in cash. If an option is  exercised,  the terms of sale shall include no
representations  or  warranties  by the Buyer  except the  absence  of  Security
Interests with respect to the assets purchased.

     7. CONDITIONS TO OBLIGATION TO CLOSE.

should  be in  effect,  the  Site or Sites to  which  it  applies  would  not be
transferred to the Buyer at the Initial  Closing but would be transferred at the
Second Closing (provided the injunction,  judgment,  order, decree or ruling had
then been vacated)  with a net reduction in the Base Purchase  Price as provided
in ss.2(d)(iii) at the Initial Closing,  and the Closing would be held as to the
remainder of the Acquired Assets);

               (iv) the Sellers shall have  delivered to the Buyer a certificate
to the effect that each of the conditions specified above in ss.7(a)(i)-(iii) is

parties  identified in ss.3(c) of the  Disclosure  Schedule;  provided that with
respect to any Leased Site the terms of the lease for which  require the consent
of the landlord or other  contract  party,  if such  landlord or other  contract
party shall not have consented to the transactions  contemplated  hereby, if the
Buyer so elects,  the Buyer may elect not to  purchase  such Site at the Initial
Closing,  and the purchase of such Site shall be postponed to the Second Closing

damage or expense arising from the failure to obtain such consent as provided in
ss.8(g);   and  further  provided  that  if  the  Buyer  has  received  estoppel

Policy  of Title  Insurance  for  certain  of the  Leased  Sites,  both in forms
acceptable  to the  Buyer,  dated no  earlier  than the date of this  Agreement,
naming the Buyer as the  proposed  insured in an amount equal to the fair market

a  state  of  title  to each of the  Sites,  together  with  all  exceptions  or
conditions  to  such  title,  including,  but not  limited  to,  all  easements,
restrictions,  rights-of-way,  covenants,  reservations,  and other encumbrances
affecting each of the Sites and (ii) contain the express commitment of the Title
Company to issue the Owner's and Leasehold  Policies of Title Insurance  without
the standard  customary  printed  exceptions  of such  policies  with respect to

liens,  specifically  stating any condition or requirement to affect the removal

Buyer's counsel may reasonably require;

each Site by a registered  surveyor  reasonably  satisfactory to the Buyer.  The
Seller  shall  cooperate  with the Buyer and the surveyor in  coordinating  such
survey.  The survey shall be certified as of a date no earlier than  December 1,
1997,  and should be prepared in accordance  with the "minimum  standard  detail

the Buyer shall not have shown any liens, encumbrances,  encroachments,  lack of
access or other matters which would have a material adverse effect on the use of
such Site as a communications  tower facility (provided,  that if any such title
examination  or survey  reveals a condition  which  constitutes  a Defect and is
unsatisfactory  to the Buyer,  the Buyer may elect not to purchase  such Site at
the Initial  Closing and to purchase such Site at the Second  Closing  (provided
such Defect shall then have been cured) as provided in  ss.2(d)(iii)  unless the
Buyer  elects to  include  such  Site,  subject  to the  Sellers'  agreement  to
indemnify the Buyer in respect of any cost,  damage or expense arising from such

Buyer and  refuses to consent to the Site  Sublease,  the Buyer may elect not to
purchase  such Site at the  Initial  Closing  and to  purchase  such Site at the
Second Closing  (provided such landlord shall by that date have entered a direct
lease,  executed a nondisturbance  agreement or consented to a Site Sublease) as
provided in ss.2(d)(iii)  unless the Buyer elects to include such Site,  subject

(provided that if the Buyer notifies the Seller that it is dissatisfied with the
results of any such  assessment,  the Buyer may elect to exclude  such Site from

     8. INDEMNIFICATION.

          (a)  SURVIVAL  OF   REPRESENTATIONS   AND   WARRANTIES.   All  of  the
representations  and  warranties of the Sellers and the Buyer  contained in ss.3
and ss.4 of this Agreement  shall survive the Closing and continue in full force
and  effect  for  a  period  of  twelve  months,  except  (i)  in  the  case  of
representations  and  warranties  pertaining  to  authority  and taxes,  and the
Sellers'  representation  that personal property included in the Acquired Assets
is free of Security  Interests,  which shall survive  indefinitely  and (ii) the
Sellers'  representations and warranties as to title to the real property at the
Owned Sites, which shall terminate at the Closing.

          (b) INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE BUYER.

               (i) In the event the Sellers breach any of their representations,
warranties,  and covenants  contained in this Agreement,  and, provided that the
Buyer makes a written claim for indemnification  against the Sellers pursuant to
ss.10(g) below with respect to Sellers'  representations  and warranties  within
the survival  period  pursuant to ss.8(a)  above,  then the Sellers  jointly and
severally  agree to  indemnify  the Buyer from and against  the  entirety of any
Adverse  Consequences  the Buyer shall suffer  through and after the date of the
claim for  indemnification  caused by the breach;  provided,  however,  that the
Sellers  shall not have any  obligation  to indemnify the Buyer from and against
any Adverse  Consequences caused by the breach of any representation or warranty
of the Sellers:  (A) until the Buyer has suffered Adverse Consequences by reason
of all such  breaches in excess of a deductible in the amount of $100,000 in the
aggregate (after which point the Sellers will be obligated only to indemnify the
Buyer from and against further such Adverse  Consequences)  or thereafter (B) to
the extent the Adverse Consequences the Buyer has suffered by reason of all such
breaches exceeds $5,000,000 in the aggregate (after which point the Sellers will
have no obligation to indemnify the Buyer from and against  further such Adverse
Consequences).

               (ii) The Sellers  agree  jointly and  severally to indemnify  the
Buyer from and against the entirety of any Adverse  Consequences the Buyer shall
suffer  caused  proximately  by any  liability  of the  Sellers  which is not an
Assumed  Liability  (including  any  liability  of the  Sellers  that  becomes a
liability of the Buyer under any bulk  transfer law of any  jurisdiction,  under
any common law doctrine of de facto merger or successor liability,  or otherwise
by  operation  of law)  or by  Sellers'  ownership  or  operation  of any of the
Acquired Assets on or prior to the Closing Date.

          (c) INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE SELLERS.

               (i) In the event the Buyer  breaches any of its  representations,
warranties,  and covenants contained in this Agreement,  and provided that, with
respect to representations and warranties,  the Sellers make a written claim for
indemnification  against the Buyer  pursuant to 10(g) below  within the survival
period set forth in ss.8(a)  above,  the Buyer agrees to  indemnify  the Sellers
from and against the  entirety of any  Adverse  Consequences  the Sellers  shall
suffer  through  and  after  the  date of the  claim  for  indemnification  (but
EXCLUDING any Adverse Consequences the Sellers shall suffer after the end of any
applicable statute of limitations).

                                       28
<PAGE>

               (ii) The Buyer agrees to  indemnify  the Sellers from and against
the entirety of any Adverse  Consequences the Sellers shall suffer caused by any
liability of the Sellers which is an Assumed Liability.

          (d) MATTERS INVOLVING THIRD PARTIES.

               (i) If any third party shall  notify any Party (the  "Indemnified
Party") with respect to any matter (a "Third Party  Claim")  which may give rise
to a claim for  indemnification  against  the  other  Party  (the  "Indemnifying
Party") under this ss.8, then the  Indemnified  Party shall promptly (and in any
event within ten business days after receiving  notice of the Third Party Claim)
notify the Indemnifying Party thereof in writing;  provided,  however,  that any
failure to give timely  notice  shall limit a party's  right to  indemnification
only to the extent of any prejudice caused by such delay.

               (ii) The  Indemnifying  Party  will have the right at any time to
assume and thereafter  conduct the defense of the Third Party Claim with counsel
of its  choice  reasonably  satisfactory  to the  Indemnified  Party;  provided,
however,  that the  Indemnifying  Party  will not  consent  to the  entry of any
judgment  or enter into any  settlement  with  respect to the Third  Party Claim
without the prior written consent of the  Indemnified  Party (not to be withheld
unreasonably)  unless the  judgment or  proposed  settlement  involves  only the
payment of money damages and does not impose an  injunction  or other  equitable
relief upon the Indemnified Party.

               (iii) Unless and until the Indemnifying Party assumes the defense
of the  Third  Party  Claim as  provided  in  ss.8(d)(ii)  above,  however,  the
Indemnified  Party may defend  against  the Third  Party  Claim in any manner it
reasonably may deem appropriate.

               (iv) In no event will the Indemnified  Party consent to the entry
of any  judgment or enter into any  settlement  with  respect to the Third Party
Claim without the prior  written  consent of the  Indemnifying  Party (not to be
withheld unreasonably).

          (e)  DETERMINATION  OF ADVERSE  CONSEQUENCES.  The Parties  shall make
appropriate  adjustments  for tax benefits and insurance  coverage and take into
account the time cost of money (using 10% as the discount  rate) in  determining
Adverse  Consequences  for purposes of this ss.8. All  indemnification  payments
under this ss.8 shall be deemed adjustments to the Purchase Price.

          (f) EXCLUSIVE REMEDY. The Buyer and the Sellers  acknowledge and agree
that after the Closing Date the  foregoing  indemnification  provisions  in this
ss.8 shall be the exclusive  remedy of the Buyer and the Sellers with respect to
the Arch Tower Business, the Acquired Assets, and the transactions  contemplated
by this Agreement;  provided,  however, that the Buyer has the right as provided
in this Agreement to cause the Sellers to reacquire certain Sites as provided in
ss.2(d)(iii)  above;  and  further  provided  this  clause  shall not operate to
exclude  other  rights the Buyer may have in respect of the  Sellers'  breach of
Section 3(n).

          (g) INDEMNIFICATION WITH RESPECT TO CERTAIN MATTERS.

                                       29
<PAGE>

               (i) To the extent the Buyer  notifies the Seller in writing prior
to the  Closing  it  wishes  to  avail  itself  of  the  provisions  of  Section
2(d)(iii)(b)  in respect of matters  described  in clause (ii)  hereof,  and the
Sellers elect to indemnify the Buyer in respect of such matters and therefore an
affected  Site is included in the  transaction,  the  provisions of this ss.8(g)
shall apply.

               (ii) Matters  covered by this ss.8(g) are Security  Interests and
Defects  existing as of the Closing Date and  conditions to closing with respect
to any Site which have not been satisfied as of the Closing Date.

               (iii) If the  Sellers  elect  not to  indemnify  the  Buyer as to
Defects or Security  Interests  in respect of a Site,  the Base  Purchase  Price
shall be adjusted as provided in ss.2(d)(iii).

               (iv) With  respect  to any  matter  for which  the  Sellers  have
elected in writing to indemnify the Buyer pursuant to this ss.8(g),  the Sellers
shall jointly and severally indemnify the Buyer and hold the Buyer harmless from
and against any cost,  liability,  damage or expense  related to the indemnified
matter, provided that:

                    (A) the Buyer promptly notifies the Seller in respect of any
third party claims related to such matter as provided in ss.8(d),

                    (B) the Sellers'  obligation to indemnify the Buyer shall be
without regard to the $100,000  "deductible"  and the $5,000,000  maximum amount
set forth in ss.8(b),

                    (C)  the  maximum  amount  of the  Sellers'  indemnification
obligation with respect to each Site shall be equal to the sum of:

                         (i) the greater of (x) the  Annualized  Operating  Cash
Flow of such  Site,  as set forth on  Exhibit  H1,  multiplied  by 11.8,  or (y)
$100,000,  which amount shall decline by 20% for each year,  or portion  thereof
(pro rated as to such  percentage for any portion of a partial  year),  that has
passed  between the Closing  Date and the date of any claim under this  ss.8(g),
plus

                         (ii)  the  net  book  value  of  all  of  the   Buyer's
improvements  to such Site,  provided  that the maximum  indemnification  amount
under this clause (ii) for any Site shall be $300,000.

                    If the Sellers pay the Buyer as  indemnification  under this
ss.8(g)  in  respect  of any  Site an  amount  equal to the  greater  of (i) the
Adjusted  Operating  Cash Flow of the Site  multiplied by 11.8 or (ii) $100,000,
plus the net book value of all the Buyer's  improvements  to the Site, the Buyer
shall reconvey such Site to the Sellers for no additional consideration.

                                       30
<PAGE>

                    (D) the Buyer shall have given written notice to the Sellers
of such claim on or before the fifth anniversary of the Closing Date.

     9. TERMINATION.

          (a)  TERMINATION  OF  AGREEMENT.  Certain of the Parties may terminate

               (ii) the Buyer may  terminate  this  Agreement by giving  written

contained in this Agreement in any material respect,  the Buyer has notified the
Sellers of the breach, and the breach has continued without cure for a period of
20 days after the notice of breach,  (B) if the Closing  shall not have occurred
on or before June 30, 1998, by reason of the failure of any condition  precedent
under ss.7(a) hereof (unless the failure results primarily from the Buyer itself
breaching any representation, warranty, or covenant contained in this Agreement)
or (C) in accordance with ss.5(g); and

               (iii) the Sellers may terminate  this Agreement by giving written

after the notice of breach,  (B) if the  Closing  shall not have  occurred on or

Agreement), or (C) in accordance with ss.5(g).

          (b) EFFECT OF  TERMINATION.  If any Party  terminates  this  Agreement

be unreasonably withheld or delayed); provided, however, that any Party may make
any public disclosure it believes in good faith is required by applicable law or

<PAGE>

breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence.

          (j) ACTION BY SELLERS.  Any right, action or notice which may be taken
exercised  or given by the Sellers  hereunder  may be taken on behalf of all the
Sellers by Arch Communications  Enterprises ("ACE").  Each of the Sellers hereby
appoints  ACE as its agent to take any action  for and on behalf of such  Seller
necessary or  appropriate  to carry out the  transactions  contemplated  by this
Agreement.

          (k)  SEVERABILITY.  Any term or  provision of this  Agreement  that is
invalid or unenforceable  in any situation in any jurisdiction  shall not affect
the validity or  enforceability  of the remaining terms and provisions hereof or
the validity or  enforceability  of the offending term or provision in any other
situation or in any other jurisdiction.

          (l)  EXPENSES.  Each of the  Sellers  and the Buyer  will bear its own
costs and expenses  (including  legal fees and expenses)  incurred in connection
with this Agreement and the transactions  contemplated hereby. The Sellers shall
bear one-half,  and the Buyer shall bear  one-half,  of the expenses of filing a
Notification  and Report Form under the  Hart-Scott-Rodino  Act with the Federal
Trade Commission and the Antitrust  Division of the United States  Department of
Justice;  provided,  that if  either  party  shall  default  in its  obligations
hereunder,  the other party's damages shall include the portion of such expenses
paid by the  non-defaulting  party. The Buyer and the Sellers shall bear equally
the costs of recording fees, filing fees, deed stamps, realty transfer taxes and
similar real estate transfer costs. The Buyer shall be responsible for any sales
taxes arising  under state law in respect of the  transactions  contemplated  by
this Agreement.

          (m)  CONSTRUCTION.  The  Parties  have  participated  jointly  in  the
negotiation  and  drafting  of this  Agreement.  In the  event an  ambiguity  or
question of intent or interpretation  arises,  this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise  favoring or  disfavoring  any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign  statute  or law  shall  be  deemed  also  to  refer  to all  rules  and
regulations promulgated thereunder,  unless the context requires otherwise.  The
word "including" shall mean including without limitation.

          (n)  INCORPORATION  OF  EXHIBITS  AND  SCHEDULES.   The  Exhibits  and
Schedules  identified in this Agreement are incorporated herein by reference and
made a part hereof.

          (o) BULK TRANSFER LAWS. The Buyer  acknowledges  that the Sellers will
not comply with the provisions of any bulk transfer laws of any  jurisdiction in
connection with the transactions contemplated by this Agreement.

          (p) DESTRUCTION OF ASSETS.  In the event of loss or damage to any Site
or tower in an amount  greater  than  $5,000  between  the date  hereof  and the
Closing Date, the Sellers shall promptly  notify the Buyer thereof and use their
commercially  reasonable best efforts to repair,  replace or restore the lost or
damaged  property to its former  condition as soon as possible.  If such repair,
replacement or restoration has not been completed prior to the Closing Date, the

                                       34
<PAGE>

Parties shall  consummate the  transaction in respect of the damaged Site at the
Initial  Closing  (unless  a Defect  shall  exist as to such  Site) and the Base
Purchase  Price  shall be  decreased  by the  amount of the loss or damage  less
amounts expended by the Sellers prior to the Closing on such repair, replacement
or  restoration  (or,  if the  Sellers  have  not  undertaken  any  repair,  the
adjustment  to the Base Purchase  Price shall be equal to the estimated  cost of
repair,  as  determined  by a reasonable  third-party  estimate  obtained by the
Sellers).

          (q) SPECIFIC PERFORMANCE.  The Parties acknowledge that the towers and
the Acquired Assets are of a unique and  extraordinary  character and that money
damages  would  not be a  sufficient  remedy  for a breach  by any  Party of its
obligations under this Agreement;  therefore, in addition to any other rights or
remedies  a  nondefaulting  Party may have,  the  nondefaulting  Party  shall be
entitled  to the  remedies  of  specific  performance  or  injunctive  relief in
connection with a breach of a Party's obligations contained in this Agreement.

     IN WITNESS  WHEREOF,  the Parties hereto have executed this Agreement on as
of the date first above written.

Mr. Paul Kuzia, Executive Vice President
of Technology and Regulatory Affairs
ARCH COMMUNICATIONS GROUP, INC.
1800 West Park Drive, Suite 250
Westborough, MA  01581

Dear Paul:


In  response to your  request  for a quotation  on a quantity of * pagers and in
light of the competitive offers you have received, Motorola is please to present
the following proposal:

     QUANTITY

     Motorola agrees to sell and ARCH  COMMUNICATIONS  GROUP,  INC.  hereinafter
     ("ARCH")  agrees to order,  from time to time,  and  accept  delivery  on a
     minimum  of * pagers  within one year from date of this  Agreement  and any
     successive one year terms.

     TERM

     This  Agreement  shall become  effective  upon written  acceptance  by ARCH
     COMMUNICATIONS  GROUP,  INC. and shall continue in effect for a term of one
     year, and will automatically renew for successive one year terms subject to
     30 days written notice by either party.

     PRICE

     The applicable prices are set forth on Attachment "A" hereto.

     These prices are applicable to pagers ordered on common carrier frequencies
     for which ARCH or its  subsidiary  companies  are the licensee or bona fide
     sales agent of the  licensee.  All prices  include a primary  cell  battery
     unless otherwise noted.

     Other pagers may be ordered at standard  common carrier prices in effect at
     the time of the order and will be  counted  toward the  fulfillment  of the
     quantity   commitment.   All  products  are  quoted  for  sale  subject  to
     availability.

     These pagers carry Motorola's  standard  warranty for one year on parts and
     labor effective the date of shipment.

     NON-DISCLOSURE

     Both  ARCH  and  Motorola  recognize  the  confidentiality  of the  pricing
     information and agree to not disclose same to third parties during the term
     of this agreement, unless required by judicial or administrative order.

     In the event of any potential merger or stock sale transactions,  ARCH will
     protect this confidentiality by obtaining written Non-Disclosure Agreements
     from the parties.

     DELIVERY SCHEDULE

     Prices quoted are for pagers whose  delivery is scheduled five (5) weeks or
     later from receipt and acceptance of your processable  order at our Boynton
     Beach, Florida, headquarters. In the event Motorola cannot ship pager units
     on the  scheduled  ship date  (SSD)  with a plus  twenty one (21) day grace
     period,  ARCH will have the option to: 1) accept shipment at later date; 2)
     cancel shipment or not accept delivery  without  penalty;  or 3) agree to a
     mutually acceptable replacement product.

     CHANGE ORDERS

     Change orders  requested by ARCH and accepted by Motorola  within three (3)
     weeks of the acknowledged shipment date may, at Motorola's option,  subject
     the order to a $1.50 per pager  changed  premium.  No change orders will be
     accepted  by  Motorola  within ten (10) days of the  acknowledged  shipment
     date.  Customer  agrees to accept any pagers  shipped by  Motorola  where a
     change order was rejected in writing by Motorola  because said change order
     was submitted within ten (10) days of the acknowledged shipment date.

     SHIPPING TERMS

     All pagers are sold F.O.B.  Point of Origin.  Freight and insurance are not
     included in the prices quoted.

     PAYMENT TERMS

     The special prices offered to ARCH in this proposal require that payment be
     made promptly after  shipment of open account  purchase one time per month,
     with payment  required on all invoices that are  outstanding for 30 days or
     more from invoice date, subject to acceptance of product.  Payment shall be
     due in  immediately  available  funds on such date during the month that is
     mutually agreed upon.

     Any invoiced  amount which is not paid within the terms and  conditions  of
     this agreement will be considered  delinquent.  Based on acceptable  credit
     and  collection  practices,  we are  entitled  to past  due  interest  or a
     late-payment  charge on the delinquent  balance  outstanding  not to exceed
     1.5% per  month on the  outstanding  balance.  Any  past  due  interest  or
     late-payment  charge  will  become  due  and  payable  immediately  at  our
     discretion.

     ARCH  COMMUNICATIONS  GROUP, INC. also agrees to reimburse Motorola for all
     legal fees and expenses incurred in collecting any amounts due hereunder.

     TAXES

     Sales and use taxes are not  included  in the prices  quoted.  They will be
     invoiced at prevailing rates unless a current Tax Exemption Certificate for
     the shipping  destination  state has been  submitted by ARCH and is on file
     with Motorola.

     BUSINESS METHODS IMPROVEMENT INCENTIVE

     The prices in this agreement are based on the  implementation  of a revised
     system of order placement and order management. The goal of this program is
     to  provide   Motorola   with   longer-range   visibility  of  fixed  pager
     requirements  and to reduce the number  orders which are changed  within 30
     days  of  scheduled  ship  date.  We  propose,  and  ARCH  agrees,  to work
     aggressively  to implement a program under which ARCH will provide at least
     50% of  their  120-day  requirements  in  issued  Purchase  Orders.  At the
     beginning of each month,  ARCH will add the remaining 50%  requirement  for
     the next month (to complete the 100% requirement of



<PAGE>


ARCH COMM
June 10, 1998
Page 3 of 9

     that month) and add the 50%  requirement  for one additional  month.  These
     percentages  will be based on current  run-rate  by product or  forecast of
     future product changes and requirements.

     DISTRIBUTION SUPPORT

     Motorola is poised to support ARCH's distribution  efforts by continuing to
     offer  promotional,  advertising  and incentive  support  through its Co-op
     Program.  Motorola  will  assist  ARCH to  generate  a  greater  amount  of
     incremental sales by extending supplemental  promotional/advertising  funds
     for exploring new ideas to expand the demand for Motorola paging products.

     PRICES CHANGES AND SPECIAL PROMOTIONS

     The prices  quoted herein are firm for the term of this  agreement.  In the
     event  Motorola  lowers the standard  common  carrier  price of any product
     specifically   enumerated  in  this  quotation  during  the  term  of  this
     agreement, no price adjustment shall be made in these prices unless the new
     price is lower than the price for the same product quoted herein.  In which
     case, all such products  remaining to be shipped under this agreement shall
     be shipped at the new, lower, general market price.

     If, during the term of this agreement,  Motorola offers a special promotion
     on any product covered by this quotation,  ARCH may select the lower of the
     standard,  general market common carrier  promotional price or the price in
     this  agreement.  The  promotional  allowance  may not be deducted from the
     price in this quotation.

     GOVERNMENT SALES

     In the event ARCH elects to sell Motorola  products or services to any U.S.
     federal,  state or local, or any foreign  government  agency, or to a prime
     contractor  or  subcontractor  selling to such entity,  ARCH shall do so at
     their  own  option  and risk  and  agrees  not to  obligate  Motorola  as a
     subcontractor or otherwise to such ARCH  COMMUNICATIONS  GROUP, Inc. except
     as  indicated in the  paragraph  below.  ARCH  COMMUNICATIONS  GROUP,  INC.
     remains  solely  and  exclusively   responsible  for  compliance  with  all
     statutes,  regulations  and clauses  governing  sales to any U.S.  federal,
     state or local, or any foreign  government agency, or to a prime contractor
     or  subcontractor  selling  to such  entity,  except  as  indicated  in the
     paragraph  below.  Motorola makes no  representations,  certifications,  or
     warranties whatsoever with respect to the ability of its goods, services or
     prices to satisfy any such statutes, regulations and clauses.

     Motorola  represents  that it generally  complies  with the  following  FAR
     clauses:

TERMS AND CONDITIONS

All orders placed during the term of this Agreement shall,  except to the extent
other  wise  provided  herein,  be  subject  to  Motorola's  Standard  Terms and
Conditions,  which  are  outlined  below.  By  executing  this  Agreement,  ARCH
acknowledges receipt, understanding, and acceptance of Motorola's Standard Terms
and  Conditions.  If any conflict arises between the terms of this Agreement and
the Standard Terms and Conditions, the terms of this Agreement shall prevail.

ACCEPTANCE.  The terms and conditions set forth herein and in Motorola's Limited
Warranty (a copy of which will accompany  shipment or is available  earlier upon
request) are an essential  and material  condition of  Motorola's  acceptance of
Buyer's  order.  Unless  otherwise  provided for in writing,  ALL SALES ARE MADE
CONDITIONAL  ONLY  UPON  ACCEPTANCE  BY  BUYER OF THESE  TERMS  AND  CONDITIONS.
Motorola  shall not be bound by Buyer's terms and  conditions  unless  expressly
agreed to in  writing.  In the  absence of written  acceptance  of these  terms,
acceptance of or payment for any of the articles  covered  hereby by Buyer shall
constitute an acceptance of these terms.

DELIVERY.  All articles  shall be sold and  delivered  FOB  Motorola's  shipping
facility(ies)  unless otherwise  expressly agreed to in writing.  All stipulated
delivery or shipment dates are estimated  only.  Motorola  reserves the right to
make  deliveries in  installments  and the contract shall be severable as to any
such  installments.  Delay in delivery or other default of any installment shall
not  relieve  the  Buyer  of its  obligation  to  accept  and pay for  remaining
deliveries.  Claims for shipment  shortage or delay in delivery  shall be deemed
waived unless  presented to Motorola in writing within 30 days after delivery of
each shipment. In no event shall Motorola be liable for increased  manufacturing
costs,  loss  of  profits  or good  will,  or any  other  special,  indirect  or
consequential damages.

RESPONSIBILITY AND TITLE; SECURITY INTEREST.  Risk of loss or damage to articles
sold shall pass to the Buyer when the  articles  are  delivered to the FOB point
referred to above or to the specified  FOB point.  Buyer shall bear all costs of
their  purchase  hereunder  after delivery to the FOB point  including,  but not
limited to, insurance,  consular fees, taxes,  ocean, air and/or inland freight,
shipping  or  handling  charges and the like.  Motorola  shall  retain and Buyer
hereby grants  Motorola a security  interest and right of possession in articles
sold until Buyer  makes full  payment.  Buyer  agrees to  cooperate  in whatever
manner necessary to assist Motorola in perfection of said security interest upon
request.

PAYMENT.  Buyer shall make net payment to Motorola at Motorola's offices at 1500
Gateway Boulevard,  Boynton Beach, Florida 33426-8292, or at such other place as
Motorola may  designate in writing.  Payment  shall be made within 30 days after
the date of invoice for each product,  accessory,  or other charge. Any invoiced
amount which is not paid within the terms and  conditions of this agreement will
be considered  delinquent.  Based on acceptable credit and collection practices,
Motorola  is  entitled  to past due  interest  or a  late-payment  charge on the
delinquent  balance  outstanding not to exceed 1.5% per month on the outstanding
balance.  Any past due  interest  or  late-payment  charge  will  become due and
payable  immediately at our discretion.  Buyer also agrees to reimburse Motorola
for all  legal  fees  and  expenses  incurred  in  collecting  any  amounts  due
hereunder.

TAXES.  Except  for the  amount,  if any,  of State and Local tax  stated in the
Agreement, the prices set



<PAGE>


ARCH COMM
June 10, 1998
Page 5 of 9


forth in he Agreement  are  exclusive  of any amount for  Federal,  State and/or
Local excise,  sales, use, property,  retailer's occupation or similar taxes. If
any such excluded tax is determined  to be  applicable  to this  transaction  or
Motorola  is required  to pay or bear the burden  thereof,  the prices set forth
herein  shall be increased by the amount of such tax and any interest or penalty
thereon, and Buyer shall pay to Motorola the full amount of any such increase no
later than 30 days after receipt of an invoice therefore.

PATENT AND COPYRIGHT INDEMNIFICATION. Motorola agrees to defend, as its expense,
any suites  against a Buyer  based upon a claim that any  Motorola  manufactured
Products furnished hereunder directly infringe a U.S. Patent or copyright and to
pay costs and damages finally  awarded in any such suit,  provided that Motorola
is notified promptly in writing of the suit and at Motorola's request and at its
expenses is given control of said suit and all requested  assistance for defense
of  same.  If the use or sale of any  such  Product(s)  furnished  hereunder  is
enjoined as a result of such suit, Motorola, at its option and at not expense to
Buyer,  shall obtain for Buyer the right to use or sell such Product(s) or shall
substitute an equivalent Product reasonably  acceptable to Buyer and extend this
indemnity  thereto or shall accept the return of such  Product(s)  and reimburse
Buyer the purchase price therefore, less a reasonable charge for reasonable wear
and tear. This indemnity does not extend to any suit based upon any infringement
or alleged  infringement  of any patent or copyright by the  combination  of any
such Product(s) furnished hereunder and other elements nor does it extend to any
such  Product(s) of Buyer's design or formula.  The foregoing  states the entire
liability of Motorola for patent or  copyright  infringement.  IN NO EVENT SHALL
MOTOROLA  BE  LIABLE  FOR  INCIDENTAL  OR  CONSEQUENTIAL  DAMAGES  ARISING  FROM
INFRINGEMENT OR ALLEGED INFRINGEMENT OF PATENTS OR COPYRIGHTS.

COPYRIGHTS AND MASK WORKS. Motorola mask works and other works of authorship may
be used in and  redistributed  only with the Equipment  associated with same. No
other  use,   including  without   limitation   reproduction,   modification  or
disassembly  of such  Motorola  mask  works or  other  works  of  authorship  is
permitted.

REVERSE  ENGINEERING.  Buyer  acknowledges  Motorola's  claim that the  Motorola
Equipment  furnished  hereunder  contain  valuable trade secrets of Motorola and
therefore  agrees  that it will  not  translate,  reverse  engineer,  decompile,
disassemble or make any other unauthorized use of such Motorola Equipment. Since
unauthorized  use of such  Motorola  Equipment  will cause  irreparable  harm to
Motorola,  Buyer agrees that Motorola,  in addition to nay other remedies it may
have,  shall be  entitled to  equitable  relief to protect  such trade  secrets,
including without limitation  temporary and permanent  injunctive relief without
proof of damages.

LOGOS AND TRADEMARKS.  1) The Products shipped under the terms and conditions of
this Agreement will carry Motorola's logo or such other logo as expressly agreed
to by  Motorola.  2) In  order  that  Motorola  may  protect  and  preserve  its
trademarks, trade names, corporate slogans, corporate logo, goodwill and Product
designations, Buyer, without the express written consent of Motorola, shall have
not right to use any such marks,  names,  slogans or designations of Motorola in
the sale,  lease or  advertising  of any  Products  or on any  Product,  Product
container,  component part, business forms,  sales,  advertising and promotional
materials or other business supplies or materials, whether in writing, orally or
otherwise.

LICENSE  DISCLAIMER.  Except for the right to use the Motorola Equipment for the
purposes  provided  herein  which  arises  by  operations  of law and  except as
expressly  provided herein,  nothing contained in this Agreement shall be deemed
to grant to Buyer either directly or by implication,  estoppel or otherwise, any
license or right under any patents,  copyrights,  trademarks or trade secrets of
Motorola or any third party.

EXCUSABLE DELAY. In addition to other limitations on liability set forth in this
Agreement,  Motorola shall not be liable for any delay or failure to perform due
to any cause beyond its reasonable control.  Causes include, but are not limited
to, strikes, acts of God, acts of the Buyer,



<PAGE>

Page 6 of 9


interruptions  of   transportation  or  inability  to  obtain  necessary  labor,
materials or  facilities,  default of any  supplier,  or delays in FCC frequency
authorization  or license  grant.  In the event  Motorola is unable to wholly or
partially perform because of any cause beyond its reasonable  control,  Motorola
may terminate the Agreement without any liability to Buyer.

FCC AND OTHER GOVERNMENT MATTERS.  Buyer is solely responsible for obtaining any
licenses  from, and complying  with any rules and  regulations  required by, the
Federal  Communications  Commission ("FCC") or any other Federal, State or Local
governmental agency.

COMMUNICATIONS  SERVICES.  Buyer  agrees that  communications  services  are not
provided under the Agreement.  MOTOROLA DISCLAIMS LIABILITY FOR RANGE, COVERAGE,
AVAILABILITY OR OPERATION OF ANY SYSTEM.

LIMITATION OF LIABILITY.  EXCEPT FOR PERSONAL  INJURY AND EXCEPT AS PROVIDED FOR
IN THE SECTION `PATENT AND COPYRIGHT INDEMNIFICATION', MOTOROL'S TOTAL LIABILITY
ARISING OUT OF OR RELATED TO THIS  AGREEMENT,  WHETHER  FOR BREACH OF  CONTRACT,
WARRANTY,  MOTOROL'S  NEGLIGENCE,  STRICT  LIABILITY  IN TORT OR  OTHERWISE,  IS
LIMITED TO THE PRICE OF THE  PARTICULAR  PRODUCTS SOLD HEREUNDER WITH RESPECT TO
WHICH LOSSES OR DAMAGES ARE CLAIMED.  BUYER'S SOLE REMEDY IS TO REQUEST MOTOROLA
AT MOTOROLA'S  OPTION TO EITEHR  REFUND THE PURCHASE  PRICE OR REPAIR OR REPLACE
PRODUCTS  THAT ARE NOT AS  WARRANTED.  IN NO EVENT WILL  MOTOROLA  BE LIABLE FOR
INCIDENTIAL,  SPECIAL OR CONSEQUENTIAL DAMAGES,  INCLUDING,  BUT NOT LIMITED TO,
FRUSTRATION OF ECONOMIC OR BUSINESS EXPECTATIONS, LOSS OF PROFITS, LOSS OF DATE,
COST OF CAPITAL, COST OF SUBSTITUTE PRODUCT(S), FACILITIES OR SERVICES, DOWNTIME
COST OR ANY  CLAIM  AGAINST  BUYER BY ANY OTHER  PARTY,  WHETHER  FOR  BREACH OF
CONTRACT,  WARRANTY,   MOTOROLA'S  NEGLIGENCE,  STRICT  LIABILITY  IN  TORT,  OR
OTHERWISE.

INSURANCE.  It is further  understood  that  Motorola is not an insurer and that
Buyer shall obtain all insurance, if any, that is desired and that Motorola does
not  represent  or  warrant  that  Motorola   products  will  avert  or  prevent
occurrences,  or the consequences  therefrom,  which are monitored,  detected or
controlled with the use of the products.

TIME TO SUE.  Except  for money  due upon an open  account,  no action  shall be
brought  for any  breach of this  agreement  more  than two (2) years  after the
accrual  of such cause of action  except  where a shorter  limitation  period is
provided by applicable law. Except as otherwise  already disclosed in writing to
Motorola,  Buyer is not  presently  aware of any facts that could give rise to a
claim against Motorola for breach of contract, warranty, or otherwise.

NO REPRESENTATIONS. The issuance of information, advice, approvals, instructions
or cost projections by Motorola's sales personnel or other representatives shall
be deemed  expressions of personal opinion only and shall not affect  Motorola's
and Buyer's rights and obligations hereunder,  unless the same is in writing and
signed by an officer of Motorola with the explicit statement that it constitutes
an amendment to this agreement.

WARRANTIES.  Buyer will be provided with Motorola's  Limited Warranty (a copy of
which will accompany the shipment or is available  earlier upon  request).  THIS
WARRANTY IS GIVEN IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WHICH ARE
SPECIFICALLY  EXCLUDED,  INCLUDING,  WITHOUT  LIMITATION,  IMPLIED WARRANTIES OF
MERCHANTABILITY  AND FITNESS FOR A  PARTICULAR  PURPOSE.  UPON  ACCEPTANCE  OF A
SHIPMENT,  BUYER SHALL BE DEEMED TO ACKNOWLEDGE  RECEIPT OF SUCH  WARRANTIES AND
LICENSE.



<PAGE>

GENERAL.  (A) Buyer  acknowledges that it has read and understands the terms and
conditions of this Agreement and agrees to be bound by them. (B) No modification
of or additions to this  Agreement  shall be binding upon  Motorola  unless such
modification is in writing and signed by an officer of Motorola. (C) If any term
or  provision of this  Agreement  shall to any extent be held  invalid,  void or
unenforceable,  by a court or other tribunal,  then that term of provision shall
be inoperative and void insofar as it is in conflict with law, but the remaining
terms and provisions shall  nevertheless  continue in full force and effect. (D)
The  failure of  Motorola  to  insist,  in any one or more  instances,  upon the
performance of any of the terms,  covenants or conditions of this Agreement,  or
to  exercise  any  right  herein,   shall  not  be  construed  as  a  waiver  or
relinquishment of the future performance of any such term, covenant or condition
or the future  exercise  of such  right,  but the  obligation  of the Buyer with
respect to such future  performance shall continue in full force and effect. (E)
THIS  AGREEMENT  AND THE  RIGHTS AND DUTIES OF THE  PARTIES  HEREUNDER  SHALL BE
GOVERNED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS.

ALTERNATIVE  DISPUTE  RESOLUTION.  Motorola and Buyer will attempt to settle any
claim or  controversy  arising  out of this  Agreement,  except  for  actions by
Motorola to collect payment from Buyer,  through consultation and negotiation in
a spirit of mutual cooperation. If those attempts fail, then the dispute will be
mediated by a  mutually-acceptable  mediator to be chosen by Motorola  and Buyer
within 45 days after  written  notice  demanding  mediation.  Neither  party may
unreasonably  withhold consent to the selection of a mediator,  and Motorola and
Buyer  will  share the  costs of the  mediation  equally.  Motorola  and  Buyer,
however,  may postpone  mediation by mutual agreement,  until some specified but
limited discovery has been completed regarding the dispute. The parties may also
agree  to  replace  mediation  with  some  other  form  of  alternative  dispute
resolution (ADR), such as neutral fact-finding or a minitrial.

        Any dispute which cannot be resolved through  negotiation,  mediation or
        other form of ADR within  six months of the date of the  initial  demand
        for it may be submitted to the state and federal courts within  Illinois
        for   resolution,   and  Motorola  and  Buyer  hereby   consent  to  the
        jurisdiction  for state and federal courts sitting in Illinois.  The use
        of any ADR  procedures  will not be  construed  under the  doctrines  of
        laches,  waiver or  estoppel  to  adversely  affect the rights of either
        party.  Nothing in this section will prevent either party from resorting
        to judicial proceedings if (a) good faith efforts to resolve the dispute
        under these  procedures  have been  unsuccessful,  or (b) interim relief
        from a court is necessary to prevent serious and  irreparable  injury to
        one party or to others.  Motorola and Buyer  knowingly,  voluntarily and
        intentionally  waive the right  each may have to a jury with  respect to
        any such judicial proceedings.

                                   WITNESSETH:

        WHEREAS,  subject  to the terms and  conditions  set forth  herein,  the

        NOW,  THEREFORE,  in  consideration  of  the  premises  and  the  mutual
covenants  and  agreements   contained   herein  and  other  good  and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the

     1.   PURCHASE AND SALE OF PREFERRED STOCK.

failure so to qualify would have a Material Adverse Effect.

immediately prior to the Closing will consist of:

               (a)  10,000,000  shares of preferred  stock,  par value $0.01 per

<PAGE>

remedies, or (ii) to the extent the indemnification  provisions contained in the

accordance with the terms hereof for the consideration expressed herein, will be
duly and validly issued, fully paid and nonassessable, free from all transfer or
similar taxes, liens and charges and free of restrictions on transfer other than
restrictions  on transfer under this Agreement and applicable  federal and state
securities  laws,  and,  subject to the truth and  accuracy  of the  Purchasers'
representations  set forth in Section 3, will be issued in  compliance  with all
applicable  federal and state  securities  laws.  The Common Stock issuable upon
conversion  of the  Convertible  Stock  purchased  hereunder  has been  duly and
validly reserved for issuance, and upon issuance in accordance with the terms of
the Certificate of Designations, will be duly and validly issued, fully paid and
nonassessable,  free from all transfer or similar  taxes,  liens and charges and
free of restrictions on transfer other than  restrictions on transfer under this
Agreement and applicable  federal and state securities laws, and, subject to the
truth and accuracy of the  Purchasers'  representations  set forth in Section 3,
will be issued in compliance  with all applicable  federal and state  securities
laws.

          2.6  CONSENTS.  Except as set forth in SECTION  2.6 of the  Disclosure
Schedule,  no consent,  approval,  order or  authorization  of, or registration,
qualification,  designation,  declaration or filing with, any federal,  foreign,
state or local governmental  authority or any other person or entity on the part
of the Company or any of its  subsidiaries  is required in  connection  with the
consummation of the  transactions  contemplated  by the Investment  Instruments,
except for filings pursuant to applicable state securities laws and Regulation D
of the Securities Act.

          2.7  LITIGATION.  Except as set forth in SECTION 2.7 of the Disclosure
Schedule,  there is no action, suit,  proceeding or investigation pending or, to
the  Company's  knowledge,   threatened  against  the  Company  or  any  of  its
subsidiaries  which could reasonably be expected to result in a Material Adverse
Effect, nor, to the Company's  knowledge,  is there any reasonable basis for the
foregoing. Neither the Company nor any of its subsidiaries is a party or subject
to the  provisions  of any order,  writ,  injunction,  judgment or decree of any
court or government agency or instrumentality which has had, or could reasonably
be expected to result in, a Material Adverse Effect.

          2.8  INTELLECTUAL  PROPERTY  RIGHTS.  The Company and its subsidiaries
own, license or otherwise possess legally enforceable rights to use all patents,
pending patent applications, trademarks, service marks, trade names, copyrights,
trade secrets, licenses,  information,  software source code and object code and
proprietary  rights and  processes  (collectively,  the  "Intellectual  Property
Rights")  necessary  for the  Company's  and its  subsidiaries'  business as now

                                      -5-
<PAGE>

conducted.  Neither the Company nor any of its  subsidiaries  has  received  any
communications alleging that the Company or any of its subsidiaries has violated
any of the patents,  trademarks,  service marks, trade names, copyrights,  trade
secrets or other  proprietary  rights or processes of any other person or entity
which  reasonably  could be  considered  likely to result in a Material  Adverse
Effect.  To  the  Company's  knowledge,  neither  the  Company  nor  any  of its
subsidiaries is infringing upon, or in conflict with, the right or claimed right
of any third  party with  respect to any of the  Intellectual  Property  Rights.
Neither  the  Company  nor  any  of its  subsidiaries  has  licensed  any of the
Intellectual  Property Rights to any other person or entity,  nor does any other
person  or  entity  have an option  or any  other  right to  acquire  any of the
Intellectual  Property  Rights.  To its  knowledge,  both  the  Company  and its
subsidiaries  have avoided every condition,  and have not performed any act, the
occurrence  of which would result in the Company's or any  subsidiary's  loss of
any Intellectual Property Right, the loss of which would have a Material Adverse
Effect.

          2.9 COMPLIANCE WITH OTHER INSTRUMENTS.  Neither the Company nor any of
its  subsidiaries  is in  violation  or  default  of  any  provisions  of  their
respective  charters,  bylaws  or  other  organizational  documents  or  of  any
instrument,  judgment, order, writ, decree or contract to which it is a party or
by which it is bound or, to its  knowledge,  of any  provision of any federal or
state  statute,  rule or  regulation  applicable  to the  Company  or any of its
subsidiaries  which  violations  or  defaults  would,  either  alone  or in  the
aggregate,  have  a  Material  Adverse  Effect.  The  execution,   delivery  and
performance  of  the  Investment   Instruments  and  the   consummation  of  the
transactions  contemplated  hereby or  thereby  will not,  with or  without  the
passage of time and/or the giving of notice,  result in any such violation or be
in  conflict  with or  constitute  either a default  under  any such  provision,
instrument,  judgment, order, writ, decree or contract or an event which results
in the creation of any material lien,  charge or encumbrance  upon any assets of
the  Company or its  subsidiaries;  provided,  however,  that in the case of any
contract  (other than  contracts  pursuant  to which the  Company  has  incurred
indebtedness  or other  liabilities in an amount in excess of  $1,000,000),  the
foregoing  representation  shall not be deemed to have been  breached so long as
any such  resulting  violation of,  conflict with or default under such contract
would not  reasonably  be  considered  likely to  result in a  Material  Adverse
Effect.

          2.10  ABSENCE OF  LIABILITIES.  Except as set forth in SECTION 2.10 of
the Disclosure Schedule or as disclosed in the Financial  Statements (as defined
below),  since December 31, 1997 neither the Company nor any of its subsidiaries
has (i) declared or paid any dividends,  or authorized or made any  distribution
upon or with respect to any class or series of its capital stock,  (ii) incurred
any  indebtedness   for  money  borrowed  or  incurred  any  other   liabilities
individually  in excess of $500,000 or in excess of $2,000,000 in the aggregate,
(iii) made any loans or  advances to any person or entity,  other than  ordinary
advances for travel expenses,  or (iv) sold,  exchanged or otherwise disposed of

                                      -6-
<PAGE>

any of its assets or rights, other than in the ordinary course of business.

          2.11 NO CONFLICT OF  INTEREST.  Except as disclosed in the Company SEC
Reports,  the Company is not a party to any transaction  which would be required
to be  disclosed  pursuant  to Item 404 of  Regulation  S-K  ("Regulation  S-K")
promulgated by the Securities and Exchange Commission (the "SEC").

          2.12 RIGHTS OF REGISTRATION AND VOTING RIGHTS.  Except as set forth in
Section 2.12 of the Disclosure  Schedule and as contemplated in the Registration
Rights Agreement, neither the Company nor any of its subsidiaries has granted or
agreed to grant any registration  rights,  including  piggyback  rights,  to any
person or entity.  To the Company's  knowledge,  no  stockholders of the Company
have entered into any agreements  with respect to the voting of capital stock of
the Company.

          2.13 PRIVATE  PLACEMENT.  Subject in part to the truth and accuracy of
the Purchasers' representations set forth in this Agreement, the offer, sale and
issuance of the  Convertible  Stock as  contemplated by this Agreement is exempt
from the  registration  requirements  of the  Securities  Act,  and  neither the
Company  nor any  authorized  agent  acting on its  behalf  will take any action
hereafter that would cause the loss of such exemption.

          2.14  TITLE  TO  PROPERTY  AND  ASSETS.  Each of the  Company  and its
subsidiaries  owns or leases its  properties  and  assets  free and clear of all
mortgages,  liens,  loans and  encumbrances,  except such encumbrances and liens
which are  disclosed  in the  financial  statements  included in the Company SEC
Reports or which arise in the ordinary  course of business and do not materially
impair the Company's ownership or use of such properties or assets. With respect
to the properties and assets it leases, each of the Company and its subsidiaries
is in compliance with such leases,  except for such instances of  non-compliance
which,  individually  or in the  aggregate,  could not reasonably be expected to
result  in a  Material  Adverse  Effect  and,  to its  knowledge,  holds a valid
leasehold interest free of any material liens, claims or encumbrances.

          2.15 TAX RETURNS AND AUDITS.  Each of the Company and its subsidiaries
has accurately prepared and timely filed all foreign,  federal, state, local and
other tax returns  required by law to be filed by it, has paid or made provision
for the payment of all taxes shown to be due and all additional assessments, and
adequate provisions have been made and are reflected in the Financial Statements
to the extent required by U.S. generally accepted accounting principles ("GAAP")
for all  current  taxes and other  charges  to which the  Company  or any of its
subsidiaries  are subject and which are not currently  due and payable.  Neither
the Company nor any of its  subsidiaries  has filed or has been required to file
foreign  income  tax  returns.  The  Company  does  not  know of any  additional
assessments or adjustments  pending or threatened  against the Company or any of

                                      -7-
<PAGE>

its  subsidiaries for any period which could reasonably be expected to result in
a Material  Adverse Effect,  nor of any reasonable basis for any such assessment
or adjustment.

          2.16 LABOR  AGREEMENTS  AND  ACTIONS.  The  Company is not bound by or
subject to (and none of its assets or  properties is bound by or subject to) any
written or oral,  express or implied,  contract,  commitment or arrangement with
any labor union,  and since  January 1, 1995 no labor union has requested or, to
the  knowledge of the Company,  has sought to  represent  any of the  employees,
representatives or agents of the Company or any of its subsidiaries. There is no
strike or other labor dispute  involving the Company and any of its subsidiaries
pending,  or to the  knowledge  of the  Company  threatened,  which would have a
Material  Adverse  Effect,  nor is the Company  aware of any labor  organization
activity involving its employees.  To the Company's  knowledge,  the Company has
complied with all applicable federal and state equal employment opportunity laws
and  with all  other  laws  related  to  employment,  except  for  such  acts of
non-compliance which, individually or in the aggregate,  could not reasonably be
expected to result in a Material Adverse Effect.

          2.17  PERMITS.  The  Company  and  each  of its  subsidiaries  has all
franchises,  permits,  licenses  and any  similar  authority  necessary  for the
conduct of its  business as now being  conducted  by it, the lack of which would
have a Material Adverse Effect.  Neither the Company nor any of its subsidiaries
is in default in any material  respect  under any of such  franchises,  permits,
licenses  or  other  similar   authority  ,  except  for  such  defaults  which,
individually or in the aggregate, would not result in a Material Adverse Effect.

          2.18 REAL PROPERTY HOLDING CORPORATION. Neither the Company nor any of
its subsidiaries is a United States real property holding corporation within the
meaning of Internal Revenue Code Section 897(c)(2) and Section 1.897-2(c) of the
Treasury Regulations promulgated thereunder.

          2.19  FINANCIAL  STATEMENTS.  The  Company has made  available  to the
Purchasers its audited  consolidated  financial  statements  (including  balance
sheet and income  statement) as of, and for the year ended December 31, 1997 and
its unaudited  consolidated  financial  statements  (including balance sheet and
income  statement)  as of, and for the  three-month  period ended March 31, 1998
(collectively,   the  "Financial  Statements").  The  Financial  Statements  are
complete  and  correct  in  all  material   respects  and  fairly   present  the
consolidated  financial  condition and operating  results of the Company and its
subsidiaries  as of the dates  thereof.  Except  as set  forth in the  Financial
Statements,  the Company has no material  liabilities,  contingent or otherwise,
other than (i)  liabilities  paid or incurred in the ordinary course of business
subsequent  to the  dates  thereof  and (ii)  obligations  under  contracts  and
commitments  incurred in the ordinary course of business,  which, in both cases,

                                      -8-
<PAGE>

individually or in the aggregate, are not material to the financial condition or
operating results of the Company and its subsidiaries, taken as a whole.

          2.2  CHANGES.  Except as set forth in SECTION  2.20 of the  Disclosure
Schedule, since March 31, 1998, there has not been:

               (a) any change in the assets, liabilities, financial condition or
operating results of the Company and its subsidiaries from that reflected in the
Financial  Statements,  except  changes in the ordinary  course of business that
have not resulted in a Material Adverse Effect.

               (b) any waiver or compromise  by the Company or its  subsidiaries
of a valuable right or of a material debt owed to it;

               (c) any  satisfaction or discharge of any material lien, claim or
encumbrance  or payment of any  obligation  by the Company or its  subsidiaries,
except in the ordinary course of business;

               (d) any material  change to a material  contract or agreement (as
defined in Item 601(b)(10) of Regulation  S-K) by which the Company,  any of its
subsidiaries or any of their respective assets is bound or subject;

               (e)  any  material  change  in any  compensation  arrangement  or
agreement with any employee,  officer, director or stockholder of the Company or
any of its subsidiaries;

               (f) any sale,  assignment  or transfer of any  material  patents,
trademarks,  copyrights, trade secrets or other intangible assets of the Company
or any of its subsidiaries, other than in the ordinary course of business;

               (g) any resignation or termination of employment of any executive
officer  or key  employee  of the  Company or any of its  subsidiaries;  and the
Company does not know of any impending  resignation or termination of employment
of any such executive officer or key employee;

               (h)  receipt  of notice  that  there has been a loss of, or order
cancellation  by, any major customer of the Company or any of its  subsidiaries,
which loss or cancellation would result in a Material Adverse Effect;

               (i) any mortgage,  pledge, transfer of a security interest in, or
lien,  created by the Company or any of its  subsidiaries,  with  respect to any
material  portion of its  properties  or  assets,  except  liens  which are not,
individually or in the aggregate,  material to the Company and its subsidiaries,
taken as a whole;

                                      -9-
<PAGE>

               (j) any loans or  guarantees  made by the  Company  or any of its
subsidiaries to or for the benefit of its employees,  officers or directors,  or
any members of their  immediate  families,  other than travel advances and other
advances made in the ordinary course of its business;

               (k)  any   declaration,   setting   aside  or  payment  or  other
distribution in respect to any of the Company's  capital stock, or any direct or
indirect redemption,  purchase, or other acquisition of any of such stock by the
Company; or

               (l) any  arrangement  or  commitment by the Company or any of its
subsidiaries to do anything described in this Section 2.20.

          2.21 ENVIRONMENTAL AND SAFETY LAWS. Neither the Company nor any of its
subsidiaries  is in  violation  of any  applicable  statute,  law or  regulation
relating  to the  environment  or  occupational  health  and  safety  where such
violation, either individually or in the aggregate, would reasonably be expected
to have a Material Adverse Effect and, to the Company's  knowledge,  no material
expenditures are required in order to comply with any such existing statute, law
or regulation.

          2.22 FCPA.  The  Company  and its  subsidiaries  have  complied in all
material  respects with the United States Foreign Corrupt Practices Act of 1977,
as amended  (the  "FCPA"),  in  obtaining  any  consents,  licenses,  approvals,
authorizations,  rights,  and privileges in connection with the conduct of their
business and, have otherwise  conducted  their  business in compliance  with all
material  respects  with the FCPA.  Their  internal  management  and  accounting
practices  and  controls  are  adequate  to ensure  compliance  in all  material
respects with the FCPA.

          2.23 REPORTS. Since January 1, 1995, the Company has filed all reports
(including proxy  statements) and registration  statements  required to be filed
with  the SEC  (collectively,  the  "Company  SEC  Reports").  The  Company  has
previously  furnished  or made  available  to the  Purchasers  true and complete
copies of all of the Company SEC Reports filed prior to the date hereof. None of
the Company SEC Reports,  as of their  respective  dates,  contained  any untrue
statement of material  fact or omitted to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under which they were made, not  misleading.  Each of the balance
sheets  (including  the  related  notes)  included  in the  Company  SEC Reports
presents fairly, in all material respects,  the consolidated  financial position
of the Company and its subsidiaries as of the respective dates thereof,  and the
other related  statements  (including the related notes) included in the Company
SEC Reports present fairly, in all material respects,  the results of operations
and the changes in financial  position of the Company and its  subsidiaries  for
the respective  periods or as of the respective dates set forth therein,  all in
conformity with GAAP consistently applied during the periods involved, except as
otherwise noted therein and subject,  in the case of unaudited interim financial

                                      -10-
<PAGE>

statements, to the absence of footnotes and normal year-end adjustments.  All of
the Company SEC Reports,  as of their respective  dates,  complied as to form in
all material  respects with the  requirements of the Securities  Exchange Act of
1934, as amended,  the Securities Act and the applicable  rules and  regulations
thereunder.

          2.24  DISCLOSURE.   No  representation  or  warranty  of  the  Company
contained in this  Agreement  and the  Disclosure  Schedule  and other  exhibits
attached  hereto,  or in any  certificate  furnished  or to be  furnished by the
Company to the  Purchasers  at the Closing  (when read  together),  contains any
untrue  statement of a material fact or omits to state a material fact necessary
to make the  statements  contained  herein or therein not misleading in light of
the circumstances under which they were made.

limited  partnership,  certificate  of  incorporation,  bylaws or other  charter
document or of any  instrument,  judgment,  order,  writ,  decree or contract to

          6.10 AMENDMENT TO RIGHTS PLAN. The Company shall cause its Rights Plan
to be amended,  on or prior to July 31,  1998,  to provide  that the  Purchasers
shall be issued  Rights in respect of their  shares of  Convertible  Stock on or
prior to a Distribution Date (as defined in the Rights Plan) equivalent to those
Rights the Purchasers  would  otherwise have had under the Rights Plan on an "as

<PAGE>

          7.2 RESTRICTIVE AGREEMENTS PROHIBITED.  Neither the Company nor any of
its  subsidiaries  shall  become a party  to any  agreement  which by its  terms
restricts  the  Company's  performance  of  the  Investment  Instruments  or its
obligations  under the  Restated  Certificate  without the prior  consent of the
holders of a majority of the shares of  Convertible  Stock  outstanding  at such
time.

          7.3 LIMITATION ON DEBT. Capitalized terms used in this Section 7.3 and
in Section 7.4 but not defined  herein shall have the meanings  given such terms
in the Company's Indenture for the 10-7/8% Senior Discount Notes due 2008 in the
form as of the date of this Agreement (the "Senior Notes Indenture").

        So  long as at  least  50% of the  Convertible  Stock  issued  hereunder
remains  outstanding,  the Company will not, and will not permit any  Restricted
Subsidiary  to,  Incur any Debt  without  the prior  consent of the holders of a
majority of the shares of Convertible Stock outstanding at such time;  PROVIDED,
HOWEVER,  that the Company may Incur Debt and may permit a Restricted Subsidiary
to Incur Debt if at the time of such  Incurrence and after giving effect thereto
the Consolidated Cash Flow Ratio would be less than 6.5 to 1.0.

        In making the foregoing  calculation,  there shall be excluded from Debt
for purposes of  calculating  the  Consolidated  Cash Flow Ratio all Debt of the
Company and its Restricted  Subsidiaries  incurred pursuant to clause (i) of the
definition  of  Permitted  Debt,  and pro forma  effect will be given to (i) the
Incurrence  of the Debt to be incurred and the  application  of the net proceeds
therefrom to refinance other Debt and (ii) the acquisition (whether by purchase,
merger or otherwise) or  disposition  (whether by sale,  merger or otherwise) of
any  company,  entity or business  acquired or disposed of by the Company or its
Restricted  Subsidiaries,  as the case may be,  since  the first day of the most
recent full fiscal quarter,  as if such  acquisition or disposition  occurred at
the beginning of the most recent full fiscal quarter.

        Notwithstanding  the  foregoing  limitation,  the Company  may,  and may
permit its  Restricted  Subsidiaries  to, Incur the  following  additional  Debt
("Permitted Debt"):

               (i) Debt under Bank Credit  Facilities in an aggregate amount not
to exceed $150.0 million at any one time outstanding,  less any amounts by which
the commitments  thereunder are permanently  reduced  pursuant to the provisions
thereof as described  under the  "Limitation on Certain Asset Sales" covenant in
the Company's Senior Notes Indenture;

               (ii)  other  Debt of the  Company  or any  Restricted  Subsidiary
outstanding  on the date of the Senior Notes  Indenture and listed on Schedule A
thereto;


                                      -19-
<PAGE>

               (iii) Debt owed by the  Company to any  wholly  owned  Restricted
Subsidiary or owed by any wholly owned  Restricted  Subsidiary to the Company or
any other wholly owned Restricted Subsidiary (provided that such Debt is held by
the Company or such wholly owned Restricted Subsidiary);

               (iv) Debt represented by the Notes;

               (v) Debt  Incurred or Incurrable in respect of letters of credit,
bankers' acceptances or similar facilities not to exceed $5.0 million at any one
time outstanding;

               (vi) Capital Lease Obligations whose  Attributable Value does not
exceed $5.0 million at any one time outstanding;

               (vii) Debt of the Company or any Restricted Subsidiary consisting
of  guarantees,   indemnities  or  obligations  in  respect  of  purchase  price
adjustments  in  connection  with the  acquisition  or  disposition  of  assets,
including, without limitation, shares of Capital Stock;

               (viii)  Debt  of  the  Company  or  any   Restricted   Subsidiary
(including  trade letters of credit) in respect of purchase  money  obligations,
provided that the aggregate amount of such Debt outstanding at any time does not
exceed $5.0 million;

               (ix) Debt arising from the honoring by a bank or other  financial
institution of a check, draft or similar  instrument drawn against  insufficient
funds  in  the  ordinary  course  of  business,   provided  that  such  Debt  is
extinguished within two Business Days of its Incurrence; and

               (x) any  renewals,  extensions,  substitutions,  refinancings  or
replacements  (each,  for  purposes  of this  clause,  a  "refinancing")  of any
outstanding Debt, other than Debt Incurred pursuant to clause (i), (vii) or (ix)
of this definition,  including any successive  refinancings  thereof, so long as
(A) any  such  new Debt is in a  principal  amount  that  does  not  exceed  the
principal amount (or, if such Debt being refinanced  provides for an amount less
than the principal  amount  thereof to be due and payable upon a declaration  of
acceleration  thereof,  such lesser amount as of the date of  determination)  so
refinanced,  plus the amount of any premium  required  to be paid in  connection
with such refinancing pursuant to the terms of the Debt refinanced or the amount
of any premium  reasonably  determined by the Company as necessary to accomplish
such refinancing by means of a tender offer or privately negotiated  repurchase,
plus the amount of  expenses  Incurred by the  Company in  connection  with such
refinancing,  and (B) such  refinancing  Debt does not have an Average Life less
than the  Average  Life of the Debt being  refinanced  and does not have a final
scheduled  maturity earlier than the final scheduled  maturity of the Debt being

                                      -20-
<PAGE>

refinanced,  or permit  redemption at the option of the holder  earlier than the
earliest  date of  redemption  at the  option of the  holder  of the Debt  being
refinanced.

          7.4 RESTRICTED  PAYMENTS.  So long as 50% of the shares of Convertible
Stock issued  hereunder remain  outstanding,  the Company will not, and will not
permit any  Restricted  Subsidiary to,  directly or indirectly,  take any of the
following  actions  (such  payments or any other  actions  described in (but not
excluded  from)  clauses  (a)  through  (d)  being  referred  to as  "Restricted

the Company or a wholly owned Restricted Subsidiary);

               (b)  purchase,  redeem or otherwise  acquire or retire for value,

               (c) make any  loan,  advance,  capital  contribution  to or other

               (d) make any other Investment (other than a Permitted Investment)
in any person or entity;

unless at the time of, and  immediately  after  giving  effect to, the  proposed
Restricted Payment:

                    (i) no  Default  or Event of  Default  has  occurred  and is
continuing;

                    (ii) the Company  could  Incur at least $1.00 of  additional
Debt (other than Permitted Debt) in accordance with Section 7.3; and

                    (iii)  the  aggregate  amount  of  all  Restricted  Payments
declared or made after the issue date of the Notes does not exceed the sum of:

                         (A)  the   remainder  of  (x)  100%  of  the  aggregate
Consolidated  Cash Flow of the  Company  (excluding,  for  purposes  other  than
determining  whether the Company may, or may permit a Restricted  Subsidiary to,
make  Investments  in any  Person,  the net income (but not the net loss) of any
Restricted Subsidiary to the extent that the declaration or payment of dividends
or  similar  distributions  by  such  Restricted  Subsidiary  is at the  date of

                                      -21-

determination restricted, directly or indirectly, except to the extent that such
net income  could be paid to the Company or a Restricted  Subsidiary  thereof by
loans,  advances,  intercompany  transfers,  principal  repayments or otherwise)
measured on a cumulative  basis during the period  beginning on the first day of
the Company's  fiscal quarter during which the Notes were originally  issued and
ending on the last day of the  Company's  most recent  fiscal  quarter for which
internal  financial  statements  are available  ending prior to the date of such
proposed  Restricted  Payment,  minus (y) the product of 2.0 times  Consolidated
Interest  Expense accrued on a cumulative  basis during the period  beginning on
the  first day of the  Company's  fiscal  quarter  during  which the Notes  were
originally  issued]  and  ending on the last day of the  Company's  most  recent
fiscal quarter for which  internal  financial  statements  are available  ending
prior to the date of such proposed Restricted Payment; plus

                         (B) the aggregate net proceeds  received by the Company
after the initial  issuance of the Notes (including the fair market value of the
property  other than cash as  determined  by the  Company's  Board of Directors,
whose good faith  determination  will be  conclusive)  from the issuance or sale
(other than to a Restricted  Subsidiary)  of Common Stock of the Company  (which
shall not be deemed to include the issuance of the Convertible Stock); plus

                         (C) the  aggregate  net cash  proceeds  received by the
Company after the initial issuance of the Notes (including the fair market value

Directors,  whose good faith determination will be conclusive) from the issuance
or  sale  (other  than  to  a  Restricted  Subsidiary)  of  debt  securities  or
convertible securities (which shall not be deemed to include the issuance of the
Convertible  Stock) that have been  converted into or exchanged for Common Stock

     Notwithstanding the foregoing,  the Company and its Restricted Subsidiaries
may  take  any  one or more  of the  following  actions,  whether  singly  or in
combination,  so long as (with  respect to  clauses  (b)  through  (f) below) no
Default or Event of Default has occurred and is continuing:

     (a)  the  payment  of any  dividend  within  60  days  after  the  date  of
declaration  thereof if at the declaration date such payment would not have been
prohibited by the foregoing provisions;


                                      -22-
<PAGE>

     (b) payments (whether made in cash,  property or securities) by the Company
or any  Subsidiary  of  the  Company  to any  employee  of  the  Company  or any
Subsidiary of the Company in connection with the issuance or redemption of stock
of any  such  company  pursuant  to any  employee  stock  option  plan or  board
resolution  to the  extent  that such  payments  do not exceed  $500,000  in the
aggregate during any fiscal year or $2.0 million in the aggregate;

     (c)  Investments in Persons made with, or out of the net cash proceeds of a
substantially   concurrent  issuance  and  sale  (other  than  to  a  Restricted
Subsidiary) of, shares of Common Stock of the Company;

     (d) Investments in Persons all or substantially all of whose operations
are in the  telecommunications  business,  provided that the aggregate amount of
Investments pursuant to this clause (d) in all such persons or entities does not
exceed $50.0 million;

     (e) Debt  Investments  in  Benbow  in an  aggregate  amount  of up to $75.0
million; and

     (f) make  any  other  payment  or  payments  of up to $5.0  million  in the
aggregate which would otherwise constitute a Restricted Payment.

     The  Restricted  Payments  described  in clauses  (b)  through  (f) of this
paragraph  will be  Restricted  Payments  that will be  permitted to be taken in
accordance  with the  preceding  paragraph but will reduce the amount that would
otherwise be available for  Restricted  Payments under clause (iii) of the first
paragraph of this Section 7.4 and the  Restricted  Payments  described in clause
(a) of the  preceding  paragraph  will  be  Restricted  Payments  that  will  be
permitted to be taken in accordance  with the  preceding  paragraph and will not
reduce the amount that would  otherwise be  available  for  Restricted  Payments
under clause (iii) of the first paragraph of this Section 7.4.

     For the purpose of making any  calculations  pursuant to this  Section 7.4,
(i) an  Investment  will  include the fair market value of the net assets of any
Restricted  Subsidiary at the time that such Restricted Subsidiary is designated
an Unrestricted  Subsidiary and will, for the purpose of this covenant,  exclude
the fair market value of the net assets of any  Unrestricted  Subsidiary that is
designated as a Restricted Subsidiary,  (ii) any property transferred to or from
an  Unrestricted  Subsidiary  will be valued at fair market value at the time of
such transfer, provided that, in each case, the fair market value of an asset or
property is as determined by the Board of Directors of the Company in good faith
and (iii) subject to the  foregoing,  the amount of any Restricted  Payment,  if
other than cash,  will be  determined  by the Board of Directors of the Company,
whose good faith determination will be conclusive.


                                      -23-
<PAGE>

     If the aggregate  amount of all Restricted  Payments  calculated  under the
foregoing  provision  includes an  Investment in an  Unrestricted  Subsidiary or
other Person that thereafter  becomes a Restricted  Subsidiary,  such Investment
will no longer be counted as a Restricted  Payment for  purposes of  calculating
the aggregate amount of Restricted Payments.

     If an  Investment  resulted  in the  making of a  Restricted  Payment,  the
aggregate  amount of all  Restricted  Payments  calculated  under the  foregoing
provision will be reduced by the amount of any net reduction in such  Investment
(resulting from the payment of interest or dividend, loan repayment, transfer of
assets or  otherwise)  to the extent such net  reduction  is not included in the
Company's  Consolidated  Adjusted Net Income;  provided that the total amount by
which the  aggregate  amount of all  Restricted  Payments may be reduced may not
exceed the  lesser of (x) the cash  proceeds  received  by the  Company  and its
Restricted  Subsidiaries  in  connection  with  such net  reduction  and (y) the
initial amount of such Investment.

     In  computing  Consolidated  Cash  Flow  of the  Company  under  the  first
paragraph  of this  Section  7.4,  (i) the  Company  may use  audited  financial
statements for the portions of the relevant  period for which audited  financial
statements are available on the date of  determination  and unaudited  financial
statements  and other current  financial  data based on the books and records of
the Company for the  remaining  portion of such period and (ii) the Company will
be  permitted  to rely in good  faith  on the  financial  statements  and  other
financial  data  derived  from the books and  records  of the  Company  that are
available  on the  date of  determination.  If the  Company  makes a  Restricted
Payment which,  at the time of the making of such Restricted  Payment,  would in
the good faith  determination of the Company be permitted under the requirements
of the Senior Notes  Indenture,  such Restricted  Payment will be deemed to have
been made in  compliance  with the Senior Notes  Indenture  notwithstanding  any
subsequent  adjustments made in good faith to the Company's financial statements
affecting Consolidated Adjusted Net Income of the Company for any period.

power or remedy accruing to any holder of any of the  Convertible  Stock (or the
Common Stock issuable upon  conversion  thereof),  upon any breach or default of
the Company under this Agreement,  shall impair any such right,  power or remedy
of such  holder nor shall it be  construed  to be a waiver of any such breach or
default,  or an acquiescence  therein, or of or in any similar breach or default
thereafter  occurring;  nor shall any waiver of any single  breach or default be
deemed a waiver  of any  other  breach  or  default  theretofore  or  thereafter
occurring.  Any waiver,  permit, consent or approval of any kind or character on
the part of any  holder of any breach or default  under this  Agreement,  or any
waiver  on the  part of any  holder  of any  provisions  or  conditions  of this
Agreement,  must be in  writing  and  shall  be  effective  only  to the  extent
specifically  set  forth  in such  writing.  All  remedies,  either  under  this
Agreement or by law or otherwise afforded to any holder, shall be cumulative and
not alternative.

documents referred to herein constitute the entire agreement between the parties
hereto pertaining to the subject matter hereof, and any and all other written or
oral agreements existing between the parties hereto are expressly canceled.

                             REQUESTED REGISTRATION

     2.1 REQUEST FOR REGISTRATION. At any time after the date of this Agreement,
Initiating  Holders may request  registration in accordance with this Article 2.
In the event the Company  shall  receive from the  Initiating  Holders a written
request that the Company effect any  registration,  qualification  or compliance
with respect to Registrable  Securities having an aggregate offering price which
exceeds $1,000,000 (based on the then current market price), the Company will:

          (a)  promptly  give  written  notice  of  the  proposed  registration,
qualification or compliance to all other Holders; and

          (b) use its best efforts to effect such registration, qualification or
compliance as soon as practicable (including, without limitation, undertaking to
file post-effective amendments, appropriate qualifications under applicable blue
sky or other state securities  laws, and appropriate  compliance with applicable
regulations  issued  under  the  Securities  Act,  and  any  other  governmental
requirements  or  regulations)  as may be so  requested  and as would  permit or
facilitate the sale and  distribution of all or such portion of such Registrable
Securities as are  specified in such request,  together with all or such portion
of the  Registrable  Securities of any Holder or Holders joining in such request
as are  specified in a written  request  received by the Company  within 10 days
after the receipt of the written  notice from the Company  described  in Section
2.1(a);  PROVIDED,  HOWEVER, that the Company shall not be obligated to take any
action to effect any such registration,  qualification or compliance pursuant to
this Article 2:

               (i) in any particular  jurisdiction in which the Company would be
required to execute a general  consent to service of process in  effecting  such
registration, qualification or compliance, unless the Company is already subject
to service in such  jurisdiction and except as may be required by the Securities
Act;

               (ii)  within  one  hundred  and  eighty  (180)  days  immediately
following  the  effective  date of any  registration  statement  pertaining to a
firmly  underwritten  offering of  securities of the Company for its own account
(or such  lesser  period as the  managing  underwriters  of such  offering  will
allow);

                                       -3-
<PAGE>

               (iii)  After the  Company  has  effected  two (2) such  requested
registrations  pursuant to this Article 2 (not including  registrations  on Form
S-3), each such  registration  has been declared or ordered  effective,  and the
Registrable  Securities  offered  pursuant to each such  registration  have been
sold, or if the Company has effected any requested registration pursuant to this
Agreement  during the previous  six-month  period (or such shorter period as the
managing  underwriter of the Company's most recent public  offering will allow);
or

               (iv) If the  Company  then  meets  the  eligibility  requirements
applicable to the use of Form S-3 in connection  with such  registration  and is
able to effect such requested registration pursuant to Article 4 hereof.

          (c) Subject to the  foregoing  clauses (i) through  (iv),  the Company
shall file a  registration  statement  covering the  Registrable  Securities  so
requested to be registered as soon as  practicable  after receipt of the request
of the Initial Holders; PROVIDED,  HOWEVER, that if the Company shall furnish to
such  Holders  a  certificate  signed  by the  Chairman  of the  Board and Chief
Executive  Officer of the Company stating that in the good faith judgment of the
Board of Directors of the Company,  it would be  detrimental  to the Company and
its  stockholders  for such  registration  statement to be filed, or, if already
filed (but prior to effectiveness of such registration statement),  that the use
of the prospectus contained in such registration  statement would be detrimental
to the Company and its stockholders,  the Company shall have the right to defer,
postpone or interrupt such offering (including the use of any prospectus related
thereto) for a period of not more than 180 days after  receipt of the request of
the Initial Holders; PROVIDED,  FURTHER, that the Company shall not be permitted
to exercise  such  deferral  right under this Section  2.1(c) or Section  4.1(c)
hereof more than once in any 360-day period.

     2.2 UNDERWRITING.

          (a) The  distribution  of the  Registrable  Securities  covered by the
request of the  Initiating  Holders  shall be effected by means of the method of
distribution  selected  by the  Holders  holding a majority  of the  Registrable
Securities  covered by such  registration.  If such  distribution is effected by
means of an  underwriting,  the right of any Holder to registration  pursuant to
this Article 2 shall be  conditioned  upon such Holder's  participation  in such
underwriting  and the inclusion of such Holder's  Registrable  Securities in the
underwriting  (unless otherwise agreed by the Initiating  Holders) to the extent
provided herein.

          (b) If such distribution is effected by means of an underwriting,  the
Company  (together  with all Holders  proposing to distribute  their  securities
through  such  underwriting)  shall  enter  into an  underwriting  agreement  in
customary form with a

                                       -4-
<PAGE>

managing  underwriter  of  nationally  recognized  standing  selected  for  such
underwriting by a majority in interest of the Initiating Holders and approved by
the Company, which approval shall not be unreasonably withheld.  Notwithstanding
any other provision of this Article 2, if the managing  underwriter  advises the
Initiating Holders in writing that marketing factors require a limitation of the
number of shares to be  underwritten,  then the  underwriters may exclude shares
requested  to be  included  in  such  registration.  The  number  of  shares  of
Registrable Securities to be included in the registration and underwriting shall
be  allocated   first  amongst  the   Initiating   Holders  who  have  requested
registration  of  Registrable  Securities and then amongst the other Holders who
have requested  registration of Registrable  Securities in such registration and
underwriting in proportion, as nearly as practicable,  to the respective amounts
of  Registrable  Securities  held by such  Holders  at the  time of  filing  the
registration statement. No Registrable Securities excluded from the underwriting
by reason of the managing  underwriter's  marketing limitation shall be included
in such registration.

          (c) If any Holder  disapproves of the terms of the underwriting,  such
person may elect to withdraw  therefrom by written  notice to the  Company,  the
managing  underwriter and the Initiating  Holders.  The  Registrable  Securities
and/or other securities so withdrawn shall also be withdrawn from  registration;
PROVIDED,  HOWEVER,  that if by the withdrawal of such Registrable  Securities a
greater number of Registrable  Securities  held by other Holders may be included
in  such  registration  (up to the  maximum  of any  limitation  imposed  by the
underwriters),  then the Company  shall  offer to all Holders who have  included
Registrable  Securities  in the  registration  the right to  include  additional
Registrable   Securities  in  the  same   proportion  used  in  determining  the
underwriter limitation in this Section 2.2.

     2.3  INCLUSION OF SHARES BY COMPANY.  If the  distribution  of  Registrable
Securities  is being  effected by means of an  underwriting  and if the managing
underwriter  has  not  limited  the  number  of  Registrable  Securities  to  be
underwritten, the Company (i) may include securities for its own account in such
registration  if the  managing  underwriter  so  agrees  and  (ii)  may  include
securities  for the  account  of  stockholders  other  than the  Holders in such
registration  if the  managing  underwriter  so agrees and if Holders  holding a
majority of the Registrable  Securities covered by such registration  consent to
such  inclusion.  The  inclusion  of such  shares by the  Company  or such other
holders  shall be on the same terms as the  registration  of shares  held by the
Initiating  Holders.  In the event  that the  underwriters  exclude  some of the
securities to be  registered,  the  securities to be sold for the account of the
Company and any other holders shall be excluded in their  entirety  prior to the
exclusion of any Registrable Securities.

     2.4 CANCELLATION OF REGISTRATION.  A majority in interest of the Initiating
Holders shall have the right to cancel a proposed  registration  of  Registrable
Securities  pursuant to Article 2 when, in their  discretion,  market conditions
are so unfavorable as to be seriously

                                       -5-
<PAGE>

detrimental to an offering pursuant to such registration. Such cancellation of a
registration  shall  not  be  counted  as  one of the  two  (2)  such  requested
registrations  pursuant to Section 2.1(b)(iii) subject to the condition that the
Initiating  Holders shall  promptly  reimburse the Company for all  Registration
Expenses  reasonably  incurred by the Company in  connection  with the cancelled
registration, unless such registration was cancelled after having been deferred,
postponed or interrupted by the Company pursuant to Section 2.1(c) in which case
such expense reimbursement shall not be required.

                                    ARTICLE 3
                              COMPANY REGISTRATION

     3.1 NOTICE OF REGISTRATION TO HOLDERS.  If at any time or from time to time
the Company shall  determine to register any of its  securities,  either for its
own  account or the account of a security  holder or  holders,  other than (i) a
registration  relating  solely  to  employee  benefit  plans on Form S-8 (or any
successor  form),  (ii) a registration  relating solely to a Commission Rule 145
transaction on Form S-4 (or any successor form) or (iii) a registration relating
solely to an exchange offer, the Company will:

          (a) promptly give to each Holder written notice thereof, and

          (b) include in such registration (and any related  qualification under
blue sky laws or other  compliance),  and in any  underwriting  involved therein
(subject to Section 3.2), all the Registrable  Securities specified in a written
request or requests,  made within 30 days after  receipt of such written  notice
from the Company described in Section 3.1(a), by any Holder or Holders.

     3.2 UNDERWRITING.  If the registration of which the Company gives notice is
for a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the  written  notice  given  pursuant to Section
3.1(a). In such event, the right of any Holder to registration  pursuant to this
Article  3  shall  be  conditioned  upon  such  Holder's  participation  in such
underwriting  and the inclusion of such Holder's  Registrable  Securities in the
underwriting to the extent provided herein.  All Holders proposing to distribute
their  securities  through such  underwriting  shall (together with the Company)
enter  into an  underwriting  agreement  in  customary  form  with the  managing
underwriter selected for such underwriting by the Company.

          (a)  Notwithstanding  any other  provision  of this  Article 3, if the
managing  underwriter  determines that marketing factors require a limitation of
the number of shares to be underwritten, the underwriter may exclude some or all
Registrable  Securities from such  registration  and  underwriting.  The Company
shall so advise all Holders of Registrable Securities,  and the number of shares
of Common Stock to be

                                       -6-
<PAGE>

included in such  registration  shall be  allocated as follows:  first,  for the
account of the Company,  all shares of Common  Stock  proposed to be sold by the
Company;  and second,  for the account of the Holders and any other  stockholder
participating  in such  registration,  the  number of  shares  of  Common  Stock
requested  to be  included  in  the  registration  by  such  Holders  and  other
stockholders,  which shall be allocated on a pari passu basis in proportion,  as
nearly as  practicable,  to the  respective  amounts  of Common  Stock  that are
proposed to be offered  and sold by such  Holders or other  stockholders  at the
time of filing the registration  statement.  No Registrable  Securities excluded
from the underwriting by reason of the underwriters'  marketing limitation shall
be included in such registration.

          (b) The  Company  shall so advise all  Holders  and the other  holders
distributing  their securities through such underwriting of any such limitation,
and the number of shares of Registrable  Securities  held by Holders that may be
included in the registration. If any Holder disapproves of the terms of any such
underwriting,  such Holder may elect to withdraw  therefrom by written notice to
the Company and the managing  underwriter.  Any securities excluded or withdrawn
from such underwriting shall be withdrawn from such registration, but the Holder
shall continue to be bound by Article 8 hereof.

          (c) The Company  shall have the right to  terminate  or  withdraw  any
registration  initiated by it under this Article 3 prior to the effectiveness of
such  registration,  whether or not a Holder has elected to include  Registrable
Securities in such registration.


                                    ARTICLE 4
                            REGISTRATION ON FORM S-3

     4.1 REQUEST FOR REGISTRATION.

          (a) In addition to the rights set forth in Articles 2 and 3 hereof, if
a Holder or Holders  request that the Company file a  registration  statement on
Form S-3 (or any successor form to Form S-3) for a public  offering of shares of
Registrable Securities having an aggregate offering price which exceeds $500,000
(based  on the then  current  market  price)  and the  Company  is a  registrant
entitled to use Form S-3 (or any  successor  form to Form S-3) to register  such
shares for such an  offering,  the Company  shall use its best  efforts to cause
such shares to be registered for the offering as soon as practicable on Form S-3
(or any such successor form to Form S-3).

          (b) Notwithstanding the foregoing,  the Company shall not be obligated
to take any action pursuant to this Article 4:

                                       -7-
<PAGE>

               (i) in any particular  jurisdiction in which the Company would be
required to execute a general  consent to service of process in  effecting  such
registration, qualification or compliance, unless the Company is already subject
to service in such  jurisdiction and except as may be required by the Securities
Act;

               (ii) if the  Company,  within ten (10) days of the receipt of the
request of the Holder or Holders,  gives  notice of its BONA FIDE  intention  to
effect  the  filing  of a  registration  statement  with the  Commission  within
forty-five  (45) days of receipt of such  request  (other than with respect to a
registration  statement relating to a Rule 145 transaction or an offering solely
to employees);

               (iii) during the period  starting with the date of filing of, and
ending  on a date  which  is  180  days  following  the  effective  date  of,  a
registration statement described in (ii) above or filed pursuant to this Article
4 or Articles 2 or 3 hereof (or such shorter period as the managing  underwriter
of the  Company's  most recent  public  offering may agree),  provided  that the
Company is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and provided,  further, that no other
person or entity could require the Company to file a  registration  statement in
such period;

          (c) Subject to the foregoing clauses (b)(i) through (iii), the Company
shall  file a  registration  statement  on Form  S-3  covering  the  Registrable
Securities so requested to be registered as soon as practicable after receipt of
the request of the Holders; PROVIDED, HOWEVER, that if the Company shall furnish
to such Holders a certificate  signed by the Chairman of the Board and the Chief
Executive  Officer of the Company stating that in the good faith judgment of the
Board of Directors of the Company,  it would be  detrimental  to the Company and
its  stockholders  for such  registration  statement to be filed, or, if already
filed (but prior to effectiveness of such registration statement),  that the use
of the prospectus contained in such registration  statement would be detrimental
to the Company and its stockholders,  the Company shall have the right to defer,
postpone or interrupt such offering (including the use of any prospectus related
thereto)  for a period of not more than 90 days after  receipt of the request of
the  Holders;  PROVIDED,  FURTHER,  that the Company  shall not be  permitted to
exercise such deferral  right under this Section 4.1(c) or Section 2.1(c) hereof
more than once in any 360-day period.

     4.2 UNDERWRITING.

          (a) The  distribution  of the  Registrable  Securities  covered by the
registration  on  Form  S-3  shall  be  effected  by  means  of  the  method  of
distribution  selected  by the  Holders  holding a majority  of the  Registrable
Securities  covered by such  registration.  If such  distribution is effected by
means of an  underwriting,  the right of any Holder to registration  pursuant to
this Article 4 shall be conditioned upon such Holder's

                                       -8-
<PAGE>

participation in such  underwriting,  if any, and the inclusion of such Holder's
Registrable Securities in such underwriting.

          (b) If the distribution of the Registrable Securities pursuant to this
Section 4.2 is effected by means of an underwriting,  the Company (together with
all Holders proposing to distribute their securities  through such underwriting)
shall enter into an  underwriting  agreement in  customary  form with a managing
underwriter of nationally  recognized standing selected for such underwriting by
a majority in interest of the Holders  requesting  registration  on Form S-3 and
approved by the Company,  which  approval  shall not be  unreasonably  withheld.
Notwithstanding  any  other  provision  of  this  Article  4,  if  the  managing
underwriter  advises the Holders in writing  that  marketing  factors  require a
limitation of the number of shares to be underwritten, then the underwriters may
exclude some or all of the shares requested to be included in such registration,
and the number of shares of Registrable  Securities  that may be included in the
registration  and  underwriting  shall be allocated among all Holders thereof in
proportion,  as nearly as practicable,  to the respective amounts of Registrable
Securities  held  by  such  Holders  at the  time  of  filing  the  registration
statement. No Registrable Securities excluded from the underwriting by reason of
the  managing  underwriter's  marketing  limitation  shall be  included  in such
registration.

          (c) If the distribution of the Registrable Securities pursuant to this
Section  4.2 is  effected  by  means of an  underwriting  and if any  Holder  of
Registrable Securities disapproves of the terms of the underwriting, such person
may elect to withdraw  therefrom by written notice to the Company,  the managing
underwriter and the Holders. The Registrable  Securities and/or other securities
so withdrawn shall also be withdrawn from registration;  PROVIDED, HOWEVER, that
if by the  withdrawal  of  such  Registrable  Securities  a  greater  number  of
Registrable   Securities   held  by  other  Holders  may  be  included  in  such
registration (up to the maximum of any limitation  imposed by the underwriters),
then the  Company  shall  offer to all  Holders  who have  included  Registrable
Securities  in the  registration  the right to  include  additional  Registrable
Securities in the same proportion used in determining the underwriter limitation
in this Section 4.2.

     4.3 INCLUSION OF SHARES BY COMPANY.  If the distribution of the Registrable
Securities  pursuant to this  Article 4 is effected by means of an  underwriting
and if the  managing  underwriter  has not  limited  the  number of  Registrable
Securities to be  underwritten,  the Company may include  securities for its own
account  or for the  account  of others  in such  registration  if the  managing
underwriter  so agrees  and if the  number  of  Registrable  Securities  held by
Holders  requesting  registration  on Form S-3 which would  otherwise  have been
included in such registration and underwriting will not thereby be limited.  The
inclusion  of such  shares  shall be on the same  terms as the  registration  of
shares held by the Holders requesting such  registration.  In the event that the
underwriters  exclude some of the  securities to be registered on Form S- 3, the
securities to be sold for

                                       -9-
<PAGE>

the  account of the  Company  and any other  holders  shall be excluded in their
entirety prior to the exclusion of any Registrable Securities.


                                    ARTICLE 5
                            EXPENSES OF REGISTRATION

     All  Registration  Expenses  incurred in connection with any  registration,
qualification  or compliance  pursuant to Article 2 and Article 3 hereof and all
S-3  Registration  Expenses shall be borne by the Company.  All Selling Expenses
relating to Registrable  Securities  registered by the Holders shall be borne by
the Holders of such  Registrable  Securities PRO RATA on the basis of the number
of shares so registered.


                                    ARTICLE 6
                             REGISTRATION PROCEDURES

          (a) In the case of each registration  effected by the Company pursuant
to this  Agreement,  the Company will keep each Holder  advised in writing as to
the  initiation  of each  registration  and as to the  completion  thereof.  The
Company agrees to use its best efforts to effect or cause such  registration  to
permit the sale of the  Registrable  Securities  covered  thereby by the Holders
thereof in  accordance  with the  intended  method or  methods  of  distribution
thereof  described  in such  registration  statement.  In  connection  with  any
registration of any Registrable Securities pursuant to Section 2, 3 or 4 hereof,
the Company shall, as soon as reasonably possible:

               (i) use its best  efforts  to cause  the  registration  statement
filed  for  purposes  of  such  registration  to  become  effective  as  soon as
reasonably possible thereafter;

               (ii) prepare and file with the  Commission  such  amendments  and
supplements to such registration  statement and the prospectus  included therein
as  may  be  necessary  to  effect  and  maintain  the   effectiveness  of  such
registration statement for a period of (a) 180 days or (b) such longer period as
may be required in order to complete the distribution of Registrable  Securities
in connection  with a  registration  effected  pursuant to Section  4.1(a),  and
furnish to the holders of the Registrable  Securities  covered thereby copies of
any such  supplement or amendment prior to this being used and/or filed with the
Commission; and comply with the provisions of the Securities Act with respect to
the  disposition  of all  the  Registrable  Securities  to be  included  in such
registration statement;

               (iii) provide (A) the Holders of the Registrable Securities to be
included in such registration  statement,  (B) the underwriters (which term, for
purposes of this

                                      -10-
<PAGE>

Agreement, shall include a person deemed to be an underwriter within the meaning
of Section  2(11) of the  Securities  Act),  if any,  thereof,  (C) the sales or
placement  agent,  if any,  therefor,  (D) one counsel for such  underwriters or
agent, and (E) not more than one counsel for all the Holders of such Registrable
Securities,   the   opportunity  to  participate  in  the  preparation  of  such
registration  statement,  each  prospectus  included  therein  or filed with the
Commission, and each amendment or supplement thereto;

               (iv)  for a  reasonable  period  prior  to  the  filing  of  such
registration  statement,   and  throughout  the  period  specified  above,  make
available for inspection by the parties  referred to in Section  6(a)(iii) above
such financial and other  information and books and records of the Company,  and
cause the officers,  directors,  employees,  counsel and  independent  certified
public  accountants  of the  Company to respond to such  inquiries,  as shall be
reasonably  necessary,  in the judgment of the respective counsel referred to in
such Section 6(a)(iii), to conduct a reasonable investigation within the meaning
of the Securities Act; PROVIDED, HOWEVER, that each such party shall be required
to maintain in  confidence  and not  disclose to any other  person or entity any
information or records reasonably  designated by the Company in writing as being
confidential, until such time as (a) such information becomes a matter of public
record  (whether by virtue of its  inclusion in such  registration  statement or
otherwise),  or (b) such party shall be required so to disclose such information
pursuant to the subpoena or order of any court or other  governmental  agency or
body having jurisdiction over the matter, or (c) such information is required to
be set forth in such registration  statement or the prospectus  included therein
or in an amendment to such registration  statement or an amendment or supplement
to such  prospectus  in order  that  such  registration  statement,  prospectus,
amendment  or  supplement,  as the  case  may be,  does not  include  an  untrue
statement of a material  fact or omit to state  therein a material fact required
to be stated therein or necessary to make the statements therein not misleading;
and  provided,  further,  that  the  Company  need  not  make  such  information
available,  nor need it cause any  officer,  director  or employee to respond to
such inquiry,  unless each such Holder of Registrable  Securities to be included
in a  registration  statement  hereunder  and such  counsel,  upon the Company's
request,  execute and deliver to the Company an undertaking to substantially the
same effect contained in the second preceding proviso;

               (v) promptly  notify the Holders of Registrable  Securities to be
included in a registration statement hereunder, the sales or placement agent, if
any,  therefor and the managing  underwriter  of the  securities  being sold and
confirm  such advice in writing,  (A) when such  registration  statement  or the
prospectus  included  therein  or any  prospectus  amendment  or  supplement  or
post-effective  amendment has been filed, and, with respect to such registration
statement or any post-effective  amendment,  when the same has become effective,
(B) of any  comments  by the  Commission  and  by  the  blue  sky or  securities
commissioner  or regulator  of any state with respect  thereto or any request by
the Commission for amendments or supplements to such  registration  statement or
the

                                      -11-
<PAGE>

prospectus or for additional information,  (C) of the issuance by the Commission
of any stop order suspending the effectiveness of such registration statement or
the initiation of any  proceedings  for that purpose,  (D) of the receipt by the
Company of any notification  with respect to the suspension of the qualification
of the Registrable  Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose,  or (E) if it shall be the case,
at any time when a prospectus is required to be delivered  under the  Securities
Act, that such registration statement,  prospectus, or any document incorporated
by reference, in any of the foregoing contains an untrue statement of a material
fact or omits to state  any  material  fact  required  to be stated  therein  or
necessary  to make  the  statements  therein  not  misleading  in  light  of the
circumstances  then  existing,   in  which  case  such  Holders  of  Registrable
Securities  included in such registration  statement shall suspend sales of such
Registrable  Securities  until  they have been  advised by the  Company  that an
appropriate  prospectus amendment or supplement or post-effective  amendment has
been filed;  PROVIDED,  HOWEVER, that in such instance the Company shall use its
best  efforts to  promptly  file such  prospectus  amendment  or  supplement  or
post-effective  amendment  and the period  during which such Holders shall be so
required to suspend sales hereunder shall not exceed thirty (30) days;

               (vi) use its best efforts to obtain the  withdrawal  of any order
suspending   the   effectiveness   of  such   registration   statement   or  any
post-effective amendment thereto at the earliest practicable date;

               (vii) if requested by any managing  underwriter  or  underwriter,
any  placement  or sales  agent or any Holder of  Registrable  Securities  to be
included in a  registration  statement,  promptly  incorporate  in a prospectus,
prospectus  supplement  or  post-effective  amendment  such  information  as  is
required by the applicable  rules and  regulations of the Commission and as such
managing  underwriter or underwriters,  such agent or such Holder may reasonably
specify  should be  included  therein  relating  to the terms of the sale of the
Registrable  Securities  included  thereunder,  including,  without  limitation,
information  with respect to the number of Registrable  Securities being sold by
such Holder or agent or to such  underwriters,  the name and description of such
Holder,  the offering  price of such  Registrable  Securities  and any discount,
commission or other compensation  payable in respect thereof, the purchase price
being paid therefor by such  underwriters and with respect to any other terms of
the offering of the Registrable Securities to be sold in such offering; and make
all  required  filings  of  such  prospectus;  prospectus  supplement  or  post-
effective   amendment   promptly  after   notification  of  the  matters  to  be
incorporated  in  such  prospectus,   prospectus  supplement  or  post-effective
amendment;

               (viii)  furnish to each Holder of  Registrable  Securities  to be
included in such  registration  statement  hereunder,  each  placement  or sales
agent,  if any,  therefor,  each  underwriter,  if any,  thereof and the counsel
referred to in Section 6(a)(iii) an

                                      -12-

thereto (in each case  excluding  all exhibits  and  documents  incorporated  by
reference) and such number of copies of the  registration  statement  (excluding
exhibits  thereto  and  documents   incorporated  by  reference  therein  unless
specifically so requested by such holder, agent or underwriter,  as the case may
be) of the prospectus  included in such registration  statement  (including each
preliminary  prospectus  and any summary  prospectus),  in  conformity  with the
requirements  of the  Securities  Act,  as  such  Holder,  agent,  if  any,  and
underwriter,  if  any,  may  reasonably  request  in  order  to  facilitate  the
disposition  of the  Registrable  Securities  owned by such  Holder sold by such
agent or underwritten by such  underwriter and to permit such Holder,  agent and
underwriter to satisfy the prospectus  delivery  requirements  of the Securities
Act;  and the  Company  hereby  consents to the use of such  prospectus  and any
amendment  or  supplement  thereto by each such Holder and by any such agent and
underwriter,  in each case in the form most  recently  provided to such party by
the  Company,  in  connection  with the  offering  and  sale of the  Registrable
Securities  covered by the prospectus  (including  such  preliminary and summary
prospectus) or any supplement or amendment thereto;

               (ix)  use  its  best  efforts  to (A)  register  or  qualify  the
Registrable  Securities to be included in such registration statement under such
other securities laws or blue sky laws of such jurisdictions to be designated by
the Holders of a majority of such Registrable  Securities  participating in such
registration   and  each  placement  or  sales  agent,  if  any,   therefor  and
underwriter, if any, thereof, as any Holder and each underwriter, if any, of the
securities being sold shall reasonably  request,  (B) keep such registrations or
qualifications  in  effect  and  comply  with  such  laws  so as to  permit  the
continuance of offers,  sales and dealings therein in such  jurisdictions for so
long as may be necessary to enable such Holder, agent or underwriter to complete
its  distribution of the Registrable  Securities  pursuant to such  registration
statement and (C) take any and all such actions as may be  reasonably  necessary
or advisable to enable such Holder, agent, if any, and underwriter to consummate
the disposition in such jurisdictions of such Registrable Securities;  provided,
however,  that the  Company  shall not be required  for any such  purpose to (1)
qualify  generally to do business as a foreign company or a broker-dealer in any
jurisdiction  wherein it would not  otherwise be required to qualify but for the
requirements of this Section 6(a)(ix),  or (2) subject itself to taxation in any
such jurisdiction;

               (x) cooperate with the Holders of the  Registrable  Securities to
be included in a registration  statement hereunder and the managing underwriters
to facilitate the timely  preparation and delivery of certificates  representing
Registrable  Securities  to  be  sold,  which  certificates  shall  be  printed,
lithographed  or engraved,  or produced by any  combination of such methods,  on
steel engraved  borders and which shall not bear any  restrictive  legends;  and
enable such Registrable Securities to be in such denominations

                                      -13-

and registered in such names as the managing  underwriters  may request at least
two business days prior to any sale of the Registrable Securities;

               (xi) provide a CUSIP number for all Registrable  Securities,  not
later than the effective date of the registration statement;

               (xii) enter into one or more underwriting agreements,  engagement
letters,  agency agreements,  "best efforts" underwriting  agreements or similar
agreements, as appropriate,  and take such other actions in connection therewith
as the Holders of at least a majority of the Registrable  Securities  being sold
shall  reasonably  request in order to expedite or facilitate the disposition of
such  Registrable  Securities;   PROVIDED,  HOWEVER,  that  notwithstanding  the
foregoing under no  circumstances  shall the Company be required to consent to a
"lock-up" or otherwise  be subject to any  restrictions  on its ability to issue
shares of capital stock for a period in excess of ninety (90) days, and PROVIDED
FURTHER,  HOWEVER, that the Company shall be permitted to issue Common Stock (a)
to any  transferee  that agrees to be bound to the same extent as the Company by
such  "lock-up"  provisions  for the  remainder of such 90-day period and (b) in
connection with the exercise of stock options pursuant to its stock option plans
or the exercise of previously  outstanding  stock warrants or other  convertible
securities;

               (xiii) whether or not an agreement of the type referred to in the
preceding  subsection  if entered  into and  whether  or not any  portion of the
offering contemplated by such registration statement is an underwritten offering
or is made though a placement or sales agent or any other entity,  (A) make such
representations and warranties to the Holders of such Registrable Securities and
the placement or sales agent,  if any,  therefor and the  underwriters,  if any,
thereof in form,  substance and scope as are customarily made in connection with
any offering of equity securities  pursuant to any appropriate  agreement and/or
to a registration  statement filed on the form  applicable to such  registration
statement; (B) obtain an opinion of counsel to the Company in customary form and
covering such matters,  of the type customarily  covered by such an opinion,  as
the managing underwriters,  if any, and as the Holders of at least a majority of
such Registrable  Securities may reasonably  request,  addressed to such Holders
and the placement or sales agent, if any, therefor and the underwriters, if any,
thereof and dated the effective date of such registration statement (and if such
registration statement contemplates an underwritten offering of a part or of all
of the  Registrable  Securities,  dated  the  date  of  the  closing  under  the
underwriting agreement relating thereto) (it being agreed that the matters to be
covered by such opinion shall include, without limitation,  the due organization
of the Company, and its subsidiaries,  if any; the qualification of the Company,
and its subsidiaries, if any, to transact business as foreign companies; the due
authorization,  execution and delivery of this agreement and of any agreement of
the type referred to in Section 6(a)(xii) hereof; the due  authorization,  valid
issuance,  and the fully paid  status of the Common  Stock of the  Company;  the

                                      -14-
<PAGE>

counsel of material legal or governmental proceedings involving the Company; the
absence  to the  knowledge  of such  counsel  of a breach by the  Company or its
subsidiaries  of, or a default  under,  agreements  binding  the  Company or any
subsidiary;  the  absence  to the  knowledge  of such  counsel  of  governmental
approvals required to be obtained in connection with the registration statement,
the  offering  and sale of the  Registrable  Securities,  this  Agreement or any
agreement of the type referred to in Section 6(a)(xii) hereof; the compliance in
all  material  respects  as to  form  of  such  registration  statement  and any
documents  incorporated  by  reference  therein  with  the  requirements  of the
Securities  Act; the  effectiveness  of such  registration  statement  under the
Securities  Act; and, in the case of a distribution  of  Registrable  Securities
which is  effected  by  means  of an  underwriting  by a  nationally  recognized
investment  banking firm,  counsel to the Company shall state that in the course
of the  preparation  of the  registration  statement  and the  prospectus,  such
counsel has participated in conferences with officers and representatives of the
Company,  representatives of the Company's  independent public accountants,  and
with the  underwriter's  representatives  and counsel,  at which conferences the
Company's counsel made inquiries of the Company's officers,  representatives and
accountants  and  discussed the contents of the  registration  statement and the
prospectus and (without  taking any further action to verify  independently  the
statements made in the registration  statement and the prospectus and, except as
stated in the Company's counsel's opinion,  without assuming  responsibility for
the accuracy,  completeness or fairness of such statements)  nothing has come to
such  counsel's  attention  that causes such  counsel to believe that either the
registration  statement  or the  prospectus  contains  any untrue  statement  of
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements  therein not  misleading  (it being  understood
that such counsel  need not express any opinion  with  respect to the  financial
statements,  schedules and other financial and statistical  data included in the
registration statement or the prospectus); (C) obtain a "cold" comfort letter or
letters  from  the  independent  certified  public  accountants  of the  Company
addressed to the Holders and the placement or sales agent, if any,  therefor and
the  underwriters,  if  any,  thereof,  dated  (I)  the  effective  date of such
registration  statement and (II) the effective date of any prospectus supplement
to the  prospectus  included in such  registration  statement or  post-effective
amendment to such  registration  statement  which includes  unaudited or audited
financial  statements  as of a date or for a  period  subsequent  to that of the
latest such statements  included in such prospectus  (and, if such  registration
statement  contemplates  an  underwritten  offering  pursuant to any  prospectus
supplement  to  the  prospectus  included  in  such  registration  statement  or
post-effective amendment to such registration statement which includes unaudited
or audited financial  statements as of a date or for a period subsequent to that
of the latest such statements included in such prospectus, dated the date of the
closing  under the  underwriting  agreement  relating  thereto),  such letter or
letters  to be  in  customary  form  and  covering  such  matters  of  the  type
customarily  covered by letters of such type;  (D) deliver  such  documents  and
certificates,  including officers' certificates,  as may be reasonably requested
by Holders of at least a majority of the Registrable Securities being

                                      -15-
<PAGE>

sold and the  placement  or  sales  agent,  if any,  therefor  and the  managing
underwriters,  if any,  thereof to evidence the accuracy of the  representations
and  warranties  made  pursuant to clause (A) above and the  compliance  with or
satisfaction  of any  agreements  or  conditions  contained in the  underwriting
agreement or other agreement entered into by the Company; and (E) undertake such
obligations relating to expense reimbursement,  indemnification and contribution
as are provided in Sections 5 and 7 hereof;

               (xiv) notify in writing each Holder of Registrable  Securities of
any proposal by the Company to amend or waive any  provision  of this  Agreement
and of any amendment or waiver effected pursuant thereto, each of which notices
shall contain the text of the amendment or waiver  proposed or effected,  as the
case may be;

               (xv) engage to act on behalf of the Company  with  respect to the
Registrable Securities to be so registered a registrar and transfer agent having
such duties and responsibilities (including, without limitation, registration of
transfers and maintenance of stock  registers) as are customarily  discharged by
such an agent,  and to enter into such agreements and to offer such  indemnities
as are customary in respect thereof; and

               (xvi)   otherwise  use  its  best  efforts  to  comply  with  all
applicable  rules and regulations of the  Commission,  and make available to its
Holders, as soon as practicable, but in any event not later than 18 months after
the  effective  date of  such  registration  statement,  an  earnings  statement
covering a period of at least twelve months which shall  satisfy the  provisions
of Section 6(a) of the Securities Act (including,  at the option of the Company,
pursuant to Rule 158 thereunder).

                    (b) In  the  event  that  the  Company  would  be  required,
pursuant  to Section  6(a)(v)(E)  above,  to notify the  Holders of  Registrable
Securities  included  in  a  registration  statement  hereunder,  the  sales  or
placement  agent,  if  any,  and  the  managing  underwriters,  if  any,  of the
securities  being  sold,  the  Company  shall  prepare  and furnish to each such
Holder,  to  each  such  agent,  if  any,  and to each  underwriter,  if any,  a
reasonable number of copies of a prospectus  supplement or amendment so that, as
thereafter  delivered  to  the  purchasers  of  Registrable   Securities,   such
prospectus  shall not contain an untrue  statement of a material fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein not misleading in light of the circumstances  then existing.
Each Holder agrees that upon receipt of any notice from the Company  pursuant to
Section  6(a)(v)(E)  hereof,   such  Holder  shall  forthwith   discontinue  the
distribution  of  Registrable  Securities  until such Holder shall have received
copies of such amended or supplemented registration statement or prospectus, and
if so directed by the Company,  such Holder shall deliver to the Company (at the
Company's expense) all

                                      -16-
<PAGE>

copies,  other than permanent file copies,  then in such Holder's  possession of
the prospectus  covering such  Registrable  Securities at the time of receipt of
such notice.

                    (c) The  Company  may  require  each  Holder of  Registrable
Securities  as to which any  registration  is being  effected  to furnish to the
Company  such  information  regarding  such Holder and such  Holder's  method of
distribution of such Registrable Securities as the Company may from time to time
reasonably  request in writing but only to the extent that such  information  is
required in order to comply with the Securities  Act. Each such Holder agrees to
notify  the  Company  immediately  of any  inaccuracy  or change in  information
previously  furnished by such Holder to the Company or of the  occurrence of any
event in  either  case as a result  of which  any  prospectus  relating  to such
registration  contains or would  contain an untrue  statement of a material fact
regarding  such Holder or the  distribution  of such  Registrable  Securities or
omits to state any material fact  regarding such Holder or the  distribution  of
such Registrable  Securities  required to be stated therein or necessary to make
the  statements  therein  not  misleading  in  light of the  circumstances  then
existing,  and  promptly to furnish to the Company  any  additional  information
required to correct and update any previously furnished  information or required
so that such  prospectus  shall not contain,  with respect to such Holder or the
distribution of such Registrable  Securities,  an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in light of the circumstances then
existing.

                                    ARTICLE 7
                                 INDEMNIFICATION

     7.1 The Company  shall  indemnify  each  Holder,  each of its  officers and
directors  and  partners,  and  such  Holder's  legal  counsel  and  independent
accountants,  if any, and each person  controlling  any such persons  within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification  or compliance has been effected  pursuant to this Agreement,  and
each  underwriter,  if any, and each person who controls any underwriter  within
the meaning of Section 15 of the Securities Act,  against all expenses,  claims,
losses,  damages and liabilities (or actions in respect thereof),  including any
of the  foregoing  incurred  in  settlement  of  any  litigation,  commenced  or
threatened,  arising out of or based on any untrue  statement (or alleged untrue
statement)  of  a  material  fact  contained  in  any  registration   statement,
prospectus,  offering circular or other document, or any amendment or supplement
thereof,  incident to any such  registration,  qualification  or compliance,  or
based on any omission (or alleged  omission) to state  therein,  a material fact
required to be stated therein or necessary to make the statements  therein,  not
misleading,  or  any  violation  by  the  Company  of  any  rule  or  regulation
promulgated  under the Securities Act or any state securities laws applicable to
the Company and relating to action or inaction by the Company in connection with
any such registration, qualification or compliance, and will reimburse each such
Holder, each

                                      -17-
<PAGE>

of its officers and directors  and partners and such Holder's  legal counsel and
independent accountants, and each person controlling any such persons, each such
underwriter and each person who controls any such underwriter, for any legal and
any  other  expenses  reasonably  incurred  in  connection  with  investigating,
preparing  or  defending  any such claim,  loss,  damage,  liability  or action;
PROVIDED,  HOWEVER,  that the Company will not be liable in any such case to the
extent that any such claim, loss, damage,  liability or expense arises out of or
is based on any untrue  statement  or omission or alleged  untrue  statement  or
omission,  made in reliance  upon and in  conformity  with  written  information
furnished  to the  Company  by or on behalf of such  Holder or  underwriter  and
expressly intended for use in such registration statement,  prospectus, offering
circular or other document, or any amendment or supplement thereof.

     7.2 Each Holder shall,  if Registrable  Securities  held by such Holder are
included  in the  securities  as to which such  registration,  qualification  or
compliance is being effected,  indemnify the Company,  each of its directors and
officers and its legal counsel and independent accountants, each underwriter, if
any, of the Company's securities covered by such a registration statement,  each
person who  controls  the  Company  or such  underwriter  within the  meaning of
Section  15 of the  Securities  Act,  and each other  such  Holder,  each of its
officers,  directors,  partners, legal counsel and independent  accountants,  if
any, and each person controlling such Holder within the meaning of Section 15 of
the  Securities  Act,  against  all  expenses,   claims,   losses,  damages  and
liabilities  (or actions in respect  thereof),  including  any of the  foregoing
incurred in settlement of any litigation,  commenced or threatened,  arising out
of or based on any untrue statement (or alleged untrue  statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other document, or any amendment or supplement thereto,  incident to any such
registration,  qualification  or compliance or based on any omission (or alleged
omission)  to state  therein a material  fact  required to be stated  therein or
necessary to make the statements therein not misleading,  and will reimburse the
Company,  such Holders,  such  directors,  officers,  partners,  legal  counsel,
independent  accountants,  underwriters  or control persons for any legal or any
other expenses reasonably  incurred in connection with investigating,  preparing
or defending any such claim, loss, damage,  liability or action, in each case to
the extent,  but only to the  extent,  that such  untrue  statement  (or alleged
untrue statement) or omission (or alleged omission) is made in such registration
statement,  prospectus,  offering  circular,  other  document  or  amendment  or
supplement in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such Holder and expressly  intended for use in
such registration statement, prospectus, offering circular or other document, or
any amendment or supplement thereof; PROVIDED,  HOWEVER, that the obligations of
each Holder  hereunder  shall be limited to an amount  equal to the  proceeds to
such Holder of Registrable Securities sold as contemplated herein.

                                      -18-
<PAGE>

     7.3 Each  party  entitled  to  indemnification  under  this  Section 7 (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom,  provided  that  counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval shall not  unreasonably  be
withheld). The Indemnified Party may participate in such defense at such party's
expense;  PROVIDED,  HOWEVER, that the Indemnifying Party shall bear the expense
of such defense of the Indemnified  Party if  representation  of both parties by
the same counsel would be inappropriate due to actual or potential  conflicts of
interest. The failure of any Indemnified Party to give notice as provided herein
shall  not  relieve  the  Indemnifying  Party  of  its  obligations  under  this
Agreement,  unless and to the extent such failure is  prejudicial to the ability
of the Indemnifying  Party to defend the action.  No Indemnifying  Party, in the
defense of any such claim or litigation,  shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which  does not  include  as an  unconditional  term  thereof  the giving by the
claimant or plaintiff to such Indemnified  Party of a release from all liability
in respect of such claim or litigation.

     7.4  If  the  indemnification  provided  for  in  Section  7.1  or  7.2  is
unavailable or  insufficient  to hold harmless an Indemnified  Party,  then each
Indemnifying  Party  shall  contribute  to the  amount  paid or  payable by such
Indemnified  Party as a result  of the  expenses,  claims,  losses,  damages  or
liabilities  (or  actions or  proceedings  in respect  thereof)  referred  to in
Section 7.1 or 7.2, in such proportion as is appropriate to reflect the relative
fault of the Company on the one hand and the sellers of  Registrable  Securities
on the other hand in connection  with  statements or omissions which resulted in
such  losses,  claims,  damages or  liabilities  (or actions or  proceedings  in
respect  thereof)  or  expenses,   as  well  as  any  other  relevant  equitable
considerations.  The relative  fault shall be  determined by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
or the  omission  or  alleged  omission  to state a  material  fact  relates  to
information supplied by the Company or the sellers of Registrable Securities and
the parties' relative intent,  knowledge,  access to information and opportunity
to correct or prevent such untrue  statement  or  omission.  The Company and the
Holders agree that it would not be just and equitable if contributions  pursuant
to this Section 7.4 were to be  determined by PRO RATA  allocation  (even if all
Sellers of Registrable  Securities  were treated as one entity for such purpose)
or by any  other  method  of  allocation  which  does  not take  account  of the
equitable  considerations referred to in the first sentence of this Section 7.4.
The amount paid by an  Indemnified  Party as a result of the  expenses,  claims,
losses,  damages or liabilities  (or actions or proceedings in respect  thereof)
referred to in the first sentence of this Section 7.4 shall be deemed to include
any legal or other expenses  reasonably  incurred by such  Indemnified  Party in
connection with

                                      -19-
<PAGE>

investigating or defending any claim,  action or proceeding which is the subject
of this Section 7.4. No person  guilty of fraudulent  misrepresentation  (within
the  meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  The  obligations  of sellers of  Registrable  Securities  to
contribute  pursuant to this Section 7.4 shall be several in  proportion  to the
respective  amount  of  Registrable  Securities  sold  by  them  pursuant  to  a
registration statement.


                                    ARTICLE 8
                               RULE 144 REPORTING

     With a  view  to  making  available  the  benefits  of  certain  rules  and
regulations  of the  Commission  which  may at  any  time  permit  the  sale  of
securities of the Company to the public without registration, after such time as
a public market exists for the Common Stock of the Company,  the Company  agrees
to:

     8.1  Make  and  keep  public  information  available  as  those  terms  are
understood and defined in Rule 144 under the Securities  Act, at all times after
the effective date of the first  registration  under the Securities Act filed by
the Company for an offering of its securities to the general public; and

     8.2 Use its best  efforts  to then  file  with the  Commission  in a timely
manner  all  reports  and other  documents  required  of the  Company  under the
Securities  Act and  the  Securities  Exchange  Act of  1934,  as  amended  (the
"Exchange Act"); and

     8.3 So long as a Holder  owns any  Registrable  Securities,  furnish to the
Holder  forthwith  upon  request a written  statement  by the  Company as to its
compliance  with  the  reporting  requirements  of  said  Rule  144,  and of the
Securities  Act and the  Exchange  Act,  a copy of the  most  recent  annual  or
quarterly  report of the Company,  and such other  reports and  documents of the
Company as a Holder may  reasonably  request in  availing  itself of any rule or
regulation  of the  Commission  allowing  a Holder  to sell any such  securities
without registration.


                                    ARTICLE 9
                         TRANSFER OF REGISTRATION RIGHTS

     The rights to cause the Company to register Registrable  Securities granted
Holders under Articles 2, 3 and 4 hereof may be assigned in connection  with any
permitted  transfer or assignment of the Holder's  Registrable  Securities.  All
transferees  and  assignees  of the  rights to cause  the  Company  to  register
Registrable  Securities  granted Holders under Articles 2, 3 and 4 hereof,  as a
condition to the transfer of such

                                      -20-
<PAGE>

rights, shall agree in writing to be bound by the agreements set forth herein.


                                   ARTICLE 10
                       LIMITATIONS ON REGISTRATION RIGHTS
                           GRANTED TO OTHER SECURITIES

     The parties hereto agree that  additional  holders may, with the consent of
the Company and the Holders of a majority  of the  Registrable  Securities  then
outstanding,  be added as parties to this  Agreement  with respect to any or all
securities of the Company held by them. Any  additional  parties shall execute a
counterpart of this Agreement, and upon execution by such additional parties and
by the Company, shall be considered Holders for purposes of this Agreement,  and
shall be added to the Schedule of Registration Rights Holders.


                                   ARTICLE 11
                                  MISCELLANEOUS

     11.1 GOVERNING  LAW. THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK  APPLICABLE TO CONTRACTS MADE
AND TO BE PERFORMED  ENTIRELY  WITHIN THE STATE WITHOUT  REGARD TO PRINCIPLES OF
CONFLICTS OF LAW.

     11.2 SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided herein,

                               EXCHANGE AGREEMENT


     This Agreement, dated as of June 29, 1998, is entered into between Adelphia
Communications Corporation, a Delaware corporation ("Adelphia"),  and Benbow PCS
Ventures, Inc., a California corporation ("Benbow").

     WHEREAS,  Adelphia holds 1,731,964 shares of Series A Redeemable  Preferred
Shares (the "Series A Stock") of Benbow; and

     WHEREAS,  the  parties  wish to  provide  that the  Series  A Stock  may be
exchanged  for shares of Common  Stock,  $.01 par value per share ("Arch  Common
Stock"), of Arch Communications Group, Inc., a Delaware corporation ("Arch"), on
the terms set forth herein;

     NOW, THEREFORE, the parties hereby agree as follows:

     1. OPTIONAL EXCHANGE.  Series A Stock shall be exchangeable for Arch Common
Stock as follows:

          (a) Each share of Series A Stock shall be exchangeable,  to the extent
Benbow can legally  acquire  such  shares of stock,  at the option of the holder
thereof,  at any time and from  time to time on or  before  April 8,  2000,  and
without the payment of additional  consideration by the holder thereof, for such
number  of fully  paid  and  nonassessable  shares  of Arch  Common  Stock as is
determined by dividing (i) $10.00 (the  "Optional  Exchange  Numerator") by (ii)
the Optional  Exchange Price (as defined below).  The "Optional  Exchange Price"
shall be the higher of (x) $13.00 (the "Optional Exchange  Denominator") and (y)
the  unweighted  average of the closing  sale prices of the Arch Common Stock on
the Nasdaq  National Market for the ten trading days  immediately  preceding the
date of  exchange.  In the event of a  liquidation  of Benbow,  the right of the
holders of shares of Series A Stock to  exchange  such  shares  for Arch  Common
Stock shall  terminate at the close of business on the first full day  preceding
the date fixed for the payment of any amounts  distributable  on  liquidation to
the holders of Series A Stock.

          (b) No fractional  shares of Arch Common Stock shall be delivered upon
exchange of the Series A Stock.  In lieu of any  fractional  shares to which the
holder would otherwise be entitled, Benbow shall pay cash equal to such fraction
multiplied by the then effective Optional Exchange Price.

          (c) In order  for a holder  of  Series A Stock to  exchange  shares of
Series A Stock for shares of Arch Common Stock,  such holder shall surrender the
certificate or certificates  for such shares of Series A Stock, at the office of
the transfer agent for the Series A Stock (or at the principal  office of Benbow
if Benbow serves as its own transfer  agent),  together with written notice that
such holder  elects to exchange  all or any number of the shares of the Series A
Stock


<PAGE>

represented by such  certificate or  certificates.  Such notice shall state such
holder's  name or the names of the  nominees  in which  such  holder  wishes the
certificate or certificates for shares of Arch Common Stock to be registered. If
required by Benbow,  certificates  surrendered for exchange shall be endorsed or
accompanied  by a  written  instrument  or  instruments  of  transfer,  in  form
satisfactory  to Benbow,  duly executed by the registered  holder or his, her or
its  attorney  duly  authorized  in  writing.   The  date  of  receipt  of  such
certificates  and notice by the transfer agent (or by Benbow if Benbow serves as
its own transfer agent) shall be the exchange date ("Optional  Exchange  Date").
Benbow shall, as soon as practicable after the Optional  Exchange Date,  deliver
at such office to such holder of Series A Stock, or to his, her or its nominees,
a certificate or  certificates  for the number of shares of Arch Common Stock to
which such holder shall be entitled,  together with cash in lieu of any fraction
of a share.

     2. MANDATORY EXCHANGE.

          (a) On April 8, 2000,  to the extent  Benbow can legally  acquire such
shares  of  stock,  each  then  outstanding   Series  A  Preferred  Share  shall
automatically  be  exchanged  for such  number of fully  paid and  nonassessable
shares of Arch  Common  Stock as is  determined  by  dividing  (i)  $10.00  (the
"Mandatory  Exchange  Numerator") by (ii) the unweighted  average of the closing
sale prices of the Arch Common Stock on the Nasdaq  National  Market for the ten
trading  days  immediately  preceding  April 8,  2000 (the  "Mandatory  Exchange
Price").

          (b) If the closing  sale price of the Arch Common  Stock on the Nasdaq
National Market for any twenty  consecutive  trading days prior to April 8, 2000
equals  or  exceeds  $13.00  (the  "Mandatory  Exchange  Benchmark"),  each then
outstanding  share of Series A Stock  shall,  to the extent  Benbow can  legally
acquire  such  shares of stock,  effective  as of the close of  business on such
twentieth trading day,  automatically be exchanged for such number of fully paid
and  nonassessable  shares of Arch Common Stock as is determined by dividing (i)
the Mandatory  Exchange  Numerator by (ii) the unweighted average of the closing
sale  prices of the Arch  Common  Stock on the Nasdaq  National  Market for such
twenty consecutive trading days (the "Benchmark Exchange Price").

          (c) All  holders of record of shares of Series A Stock  shall be given
written notice of the date (the "Mandatory  Exchange Date") and place designated
for  mandatory  exchange of all such  shares of Series A Stock  pursuant to this
Section 2. Such  notice need not be given in advance of the  Mandatory  Exchange
Date.  Such notice  shall be sent by first  class or  registered  mail,  postage
prepaid,  to each record holder of Series A Stock at such holder's  address last
shown on the  records  of the  transfer  agent  for the  Series A Stock  (or the
records of Benbow, if it serves as its own transfer agent). Upon receipt of such
notice,  each holder of shares of Series A Stock shall surrender his, her or its
certificate  or  certificates  for  all  such  shares  to  Benbow  at the  place
designated in such notice,  and shall  thereafter  receive  certificates for the
number of shares of Arch Common Stock to which such holder is entitled  pursuant
to this  Section 2. If so  required  by  Benbow,  certificates  surrendered  for
exchange shall be endorsed or  accompanied by written  instrument or instruments
of transfer,  in form  satisfactory  to Benbow,  duly executed by the registered
holder or by his, her or its attorney  duly  authorized  in writing.  As soon as
practicable  after  the  Mandatory  Exchange  Date  and  the  surrender  of  the
certificate or certificates


<PAGE>

for Series A Stock,  Benbow shall cause to be  delivered  to such holder,  or on
his, her or its written order, a certificate or  certificates  for the number of
full shares of Arch Common Stock deliverable on such exchange in accordance with
the  provisions  hereof and cash as provided in Section 1(b) above in respect of
any fraction of a share of Arch Common  Stock  otherwise  deliverable  upon such
exchange.

     3.  ADJUSTMENT  PROVISIONS.  The  Optional  Exchange  Numerator,   Optional
Exchange  Denominator,  Mandatory  Exchange  Numerator  and  Mandatory  Exchange
Benchmark (each, a "Base Price") shall be subject to adjustment as follows:

          (i) ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS.  If Arch at any time
or from  time to time  after the date of  issuance  of the  Series A Stock  (the
"Issue Date") effects a subdivision of the  outstanding  Arch Common Stock,  the
Base  Price  then  in  effect  immediately  before  such  subdivision  shall  be
proportionately  decreased, and conversely,  if Arch at any time or from time to
time after the Issue Date combines the  outstanding  shares of Arch Common Stock
into a smaller  number of  shares,  the Base  Price  then in effect  immediately
before such combination shall be proportionately increased. Any adjustment under
this  subsection (i) shall become  effective at the open of business on the date
the subdivision or combination becomes effective.

          (ii) ADJUSTMENT FOR CERTAIN  DIVIDENDS AND  DISTRIBUTIONS.  If Arch at
any time or from time to time after the Issue  Date  makes,  or fixes,  a record
date for the determination of holders of Arch Common Stock entitled to receive a
dividend  or other  distribution  payable in  additional  shares of Arch  Common
Stock,  then and in each such  event  the Base  Price  then in  effect  shall be
decreased  as of the time of such  issuance or, in the event such record date is
fixed,  as of the opening of business on such record date,  by  multiplying  the
Base Price then in effect by a fraction (A) the  numerator of which is the total
number of shares of Arch Common Stock issued and outstanding  immediately  prior
to the time of such  issuance or the close of business on such record date,  and
(B) the  denominator of which shall be the total number of shares of Arch Common
Stock issued and outstanding  immediately  prior to the time of such issuance or
the close of  business  on such  record  date plus the  number of shares of Arch
Common Stock deliverable in payment of such dividend or distribution;  PROVIDED,
HOWEVER,  that if such record date is fixed and such  dividend is not fully paid
or if such  distribution is not fully made on the date fixed therefor,  the Base
Price shall be recomputed accordingly as of the close of business on such record
date and thereafter the Base Price shall be adjusted pursuant to this subsection
(ii) as of the time of actual payment of such dividend or distribution.

          (iii) ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the event
Arch at any time or from time to time after the Issue Date  makes,  or fixes,  a
record date for the  determination  of holders of Arch Common Stock  entitled to
receive a dividend or other  distribution  payable in  securities  of Arch other
than shares of Arch Common Stock, then and in each such event provision shall be
made so that the holders of Series A Stock shall receive, upon exchange thereof,
in addition to the number of shares of Arch Common Stock  receivable  thereupon,
the amount of securities of Arch which they would have received had their Series
A Stock  been for Arch  Common  Stock  on the  date of such  event  and had they
thereafter, during the


<PAGE>

period from the date of such event to and including the exchange date,  retained
such securities  receivable by them as aforesaid during such period,  subject to
all other  adjustments  called for during such period  under this Section 3 with
respect to the rights of the holders of the Series A Stock.

          (iv) ADJUSTMENT FOR  RECLASSIFICATION,  EXCHANGE AND SUBSTITUTION.  In
the event that at any time or from time to time after the Issue  Date,  the Arch
Common Stock deliverable upon the exchange of the Series A Stock is changed into
the same or a  different  number of shares of any class or  classes of shares of
stock, whether by recapitalization,  reclassification or otherwise (other than a
subdivision  or  combination  of shares or stock  dividend or a  reorganization,
merger,  consolidation or sale of assets, provided for elsewhere in this Section
3),  then and in any such  event  each  holder of Series A Stock  shall have the
right  thereafter  to  exchange  such  Series A Stock for the kind and amount of
stock and other securities and property  receivable upon such  recapitalization,
reclassification  or other  change,  by  holders of the number of shares of Arch
Common  Stock for which such shares of Series A Stock could have been  exchanged
immediately  prior to such  recapitalization,  reclassification  or change,  all
subject to further adjustment as provided herein.

          (v)  ADJUSTMENT  FOR   CONSOLIDATION   OR  MERGER.   In  case  of  any
consolidation or merger of Arch with or into another  corporation or the sale of
all or  substantially  all of the  assets of Arch to another  corporation,  each
share of Series A Stock shall  thereafter be exchangeable (or shall be exchanged
for a security which shall be exchangeable) for the kind and amount of shares of
stock or other  securities or property to which a holder of the number of shares
of Arch Common Stock deliverable upon exchange of such Series A Stock would have
been  entitled  upon such  consolidation,  merger or sale;  and,  in such  case,
appropriate  adjustment  (as determined in good faith by the Board of Directors)
shall be made in the  application  of the provisions in this Section 3 set forth
with respect to the rights and interest  thereafter of the holders of the Series
A Stock,  to the end that  the  provisions  set  forth in this  Section  3 shall
thereafter be  applicable,  as nearly as  reasonably  may be, in relation to any
shares of stock or other property  thereafter  deliverable  upon the exchange of
the Series A Stock.

          (vi)  CERTIFICATE  OF  ADJUSTMENT.  In each case of an  adjustment  or
readjustment  of the Base Price or the number of shares of Arch Common  Stock or
other securities  deliverable upon exchange of the Series A Stock,  Benbow shall
compute such adjustment or readjustment in accordance with the provisions hereof
and prepare a certificate,  signed by its principal  financial officer,  showing
such adjustment or readjustment, and shall mail such certificate, by first class
mail,  postage prepaid,  to each registered  holder of the Series A Stock at the
holder's  address as shown in Benbow's books.  The  certificate  shall set forth
such  adjustment or  readjustment,  showing in reasonable  detail the facts upon
which such adjustment or readjustment is based, including a statement of (A) the
Base Price at the time in effect and (B) the type and  amount,  if any, of other
property  which at the time  would be  received  upon  exchange  of the Series A
Stock.

     4. EXCHANGE OF DIVIDENDS. Upon the exchange (whether optional or mandatory)
of Series A Stock for Arch  Common  Stock,  all  accrued  but  unpaid  Mandatory
Dividends (as such term is defined in the  Certificate  of  Determination  filed
with the Secretary of State of California


<PAGE>

to establish the Series A Stock (the "Certificate of Determination")),  together
with  interest  thereon  as  provided  in  Section  1(a) of the  Certificate  of
Determination,  and all other declared but unpaid dividends, if any, immediately
prior to such exchange shall be exchanged for Arch Common Stock at a price equal
to (i) in the case of optional exchange, the Optional Exchange Price (as defined
in Section  1(a)  above),  (ii) in the case of  mandatory  exchange  pursuant to
Section 2(a) above,  the  Mandatory  Exchange  Price (as defined in Section 2(a)
above),  and (iii) in the case of  mandatory  exchange  pursuant to Section 2(b)
above, the Benchmark Exchange Price (as defined in Section 2(b) above).

     5. EFFECT OF GUARANTY.  Benbow's  obligations  hereunder are  guaranteed by
Arch pursuant to a Guaranty of even date herewith.  To the extent that Arch pays
or performs under such Guaranty  Agreement,  Benbow is relieved from  performing
the corresponding obligations hereunder.

     6. TRANSFERS OF RIGHTS.  This Agreement,  and the rights and obligations of
Adelphia hereunder, may be assigned by Adelphia to any person or entity to which
Series A Stock is transferred by Adelphia; provided that the transferee provides
written notice of such assignment to Benbow.

$285,015.00                                                      June 29, 1998
                                                             Eureka, California


     FOR  VALUE  RECEIVED,  the  undersigned,   Benbow  PCS  Ventures,  Inc.,  a
California  corporation  (the "Issuer"),  hereby promises to pay to the order of
Lisa-Gaye Shearing ("LGS"), an individual with a principal place of residence at
401 South Main St.,  Coudersport,  PA 16915, or order,  the principal sum of Two
Hundred  Eighty-Five  Thousand and Fifteen  Dollars  ($285,015)  in  immediately
available funds,  together with interest,  whether before or after maturity,  at
the  rates  and on the  dates  hereinafter  provided,  on any and all  principal
amounts  outstanding  hereunder  from  time to time from the date  hereof  until
payment in full hereof.

     1. MATURITY; INTEREST RATE; INTEREST PAYMENTS.

     (a) From  April 8,  1998  until  this  Note is paid in  full,  interest  on
principal  amounts  outstanding  hereunder shall accrue and be payable at a rate
per annum equal to twelve percent (12%) per annum,  compounded  annually on each
anniversary  of the  date of this  Note,  until  payment  in full  thereof.  All
principal  and interest  outstanding  hereunder  shall be payable in full by the
Issuer on April 8, 2000 or on such earlier date as said principal may become due
and payable pursuant to the terms hereof.

     (b) All payments hereunder may be made, at the sole option of the Issuer:

          (i) in cash;

                    (ii) in such  number of shares  of  common  stock,  $.01 par
               value per share  (the  "Common  Stock"),  of Arch  Communications
               Group,  Inc.  ("Arch")  as is  determined  by  dividing  (y)  the
               outstanding amount of principal and interest due under this Note,
               by (z) the  unweighted  average of the closing sale prices of the
               Common Stock on the Nasdaq  National  Market for ten trading days
               immediately  preceding  the  maturity  date as  described in sub-
               paragraph (a) above; or

                    (iii) in a combination  of cash and Common Stock as provided
               above.



     (c) In addition to, and not in  limitation  of, the  foregoing,  during the
continuance of an event of default hereunder,  outstanding principal and, to the
extent  permitted by applicable  law,  outstanding  interest shall bear interest
from and including the due date thereof until paid at a rate


<PAGE>

per annum equal to fourteen  percent  (14%).  Such rate shall be in effect until
all of the  obligations of the Issuer to LGS are paid in full. In no event shall
any interest be at a rate in excess of the maximum rate permitted by law.

     2. DEFAULT; REMEDIES.

     At the option of the holder,  this Note shall  become  immediately  due and
payable upon the occurrence and during the continuance at any time of any of the
following  events of default:  (1) default in the payment of principal when due;
(2) default in the payment or  performance  of any other of the  liabilities  or
obligations  of the Issuer  hereunder and the failure of the Issuer to cure such
default  within 5 days;  (3) the  liquidation,  termination,  dissolution or the
appointment of a receiver for the Issuer or Arch or their respective  properties
as a whole;  (4) the institution by the Issuer or Arch of any proceedings  under
the United States Bankruptcy Code or any other federal or state law in which the
Issuer or Arch is  alleged  to be  insolvent  or unable to pay its debts as they
mature or the making by the Issuer or Arch of an  assignment  or trust  mortgage
for the benefit of creditors;  or (5) the institution against the Issuer or Arch
of any  proceedings  under the  United  States  Bankruptcy  Code or of any other
federal or state law in which the Issuer or Arch is alleged to be  insolvent  or
unable to pay its debts as they mature, and the failure of the Issuer or Arch to
cause such proceedings to be dismissed or stayed within 60 days.

     Upon an event of default,  and at all times  thereafter,  the holder  shall
have all of the rights and remedies  afforded by the Uniform  Commercial Code as
from time to time in effect in the  Commonwealth of Massachusetts or afforded by
other applicable law.

     3. PREPAYMENT.

          (a) At any time and from time to time,  the  Issuer  may  pre-pay  the
Note, in whole or in part, in cash or Common Stock or a combination  of cash and
Common Stock, as provided in Section 1(b) above.


          (b) The Issuer shall  promptly  prepay  principal  and  interest  owed
hereunder  upon the early  redemption  or early  repayment  by the Issuer of any
portion  of  its  Series  A  Redeemable   Preferred  Shares  with  such  rights,
preferences  and  privileges  as  described  in EXHIBIT A hereto (the  "Series A
Preferred  Stock");  provided  that such  prepayment  of this Note shall be made
ratably with such early redemption or early prepayment of the Series A Preferred
Stock.

          (c) In the  event  of  any  prepayment  of  only  a part  of the  then
outstanding  amount due on the Note,  the  prepayment  shall be applied first to
outstanding interest and then to outstanding principal.

     4.  OPTIONAL  EXCHANGE.  This Note may be  exchanged  into Common  Stock as
follows:

          (a) This Note may be exchanged,  at the option of the holder  thereof,
at any  time and from  time to time,  and  without  the  payment  of  additional
consideration  by the  holder  thereof,  into  such  number  of  fully  paid and
nonassessable  shares of  Common  Stock as is  determined  by  dividing  (y) the
outstanding amount of principal and interest due under this Note,


<PAGE>

by (z) product of (i) the  unweighted  average of the closing sale prices of the
Common  Stock on the Nasdaq  National  Market for ten trading  days  immediately
preceding  the Exchange  Date  (defined in Section 4(c) below) and (ii) 1.30. In
the event of a liquidation  of the Issuer,  the right of the holder of this Note
to exchange this Note for Common Stock shall  terminate at the close of business
on the first full day  preceding  the date fixed for the  payment of any amounts
distributable on liquidation to the holders of Series A Preferred Stock.

          (b) No fractional shares of Common Stock shall be issued upon exchange
of this  Note.  In lieu of any  fractional  shares  to which  the  holder  would
otherwise  be  entitled,  the  Issuer  shall pay cash in an amount  equal to the
product of (i) such  fraction,  and (ii) the  unweighted  average of the closing
sale prices of the Common  Stock on the Nasdaq  National  Market for ten trading
days immediately preceding the Exchange Date (defined in Section 4(c) below).

          (c) In order  for a holder  of this  Note to  exchange  this  Note for
shares of Common Stock, such holder shall surrender this Note and deliver to the
Issuer  written notice that such holder elects to exchange all or any portion of
the  outstanding  principal  amount of this Note.  Such notice  shall state such
holder's  name or the names of the  nominees  in which  such  holder  wishes the
certificate or certificates for shares of Common Stock to be issued. The date of
receipt  of the  Note and  notice  by the  Issuer  shall  be the  exchange  date
("Exchange  Date").  The Issuer shall, as soon as practicable after the Exchange
Date,  cause to be issued and  delivered  at such  office to such holder of this
Note or to his or its nominees,  a certificate or certificates for the number of
shares of Common  Stock to which such holder shall be  entitled,  together  with
cash in lieu of any fraction of a share.

          (d) The Issuer  shall cause Arch,  at all times  during which the Note
shall be  outstanding,  to reserve and keep  available out of its authorized but
unissued  stock,  for the purpose of effecting  the  exchange of the Note,  such
number of its duly authorized  shares of Common Stock as shall from time to time
be sufficient to effect the exchange for Common Stock of all amounts outstanding
under the Note.

          (e) If the Common Stock  issuable  upon the exchange of the Note shall
be changed into the same or a different number of shares of any class or classes
of stock,  whether by capital  reorganization,  reclassification,  or  otherwise
(other than a subdivision or  combination  or shares of stock dividend  provided
for above,  or a merger,  consolidation,  or sale of assets provided for below),
then and in each  such  event  the  holder  of the  Note  shall  have the  right
thereafter  to  exchange  the Note or the amount and kind of shares of stock and
other   securities   and   property   receivable   upon   such   reorganization,
reclassification,  or other change, by holders of the number of shares of Common
Stock into which such Note might have been exchanged  immediately  prior to such
reorganization,  reclassification,  or change, all subject to further adjustment
as provided herein.

          (f) In case  of any  consolidation  or  merger  of  Arch  with or into
another  corporation  or the sale of all or  substantially  all of the assets of
Arch to another corporation, the Note shall thereafter be exchangeable (or shall
be  exchanged  with a security  which shall be  exchangeable)  into the kind and
amount of shares of stock or other  securities  or property to which a holder of
the number of shares of Common Stock of Arch deliverable upon the exchange

<PAGE>

of such Note would have been entitled upon such  consolidation,  merger or sale;
and, in such case,  appropriate  adjustment  (as determined in good faith by the
Board of Directors)  shall be made in the  application of the provisions in this
Section 4 set forth with  respect to the rights and interest  thereafter  of the
holder,  to the end that  the  provisions  set  forth  in this  Section  4 shall
thereafter be  applicable,  as nearly as  reasonably  may be, in relation to any
shares of stock or other property  thereafter  deliverable  upon the exchange of
the Note.

     5. MANDATORY EXCHANGE.

          (a) In the event that the  closing  sale price of Common  Stock on the
Nasdaq  National  Market is equal to or greater  than  $13.00 for each of twenty
consecutive  days on which the Nasdaq National  Market is open for trading,  all
outstanding amounts due under the Note shall automatically be exchanged for such
number of fully paid and  nonassessable  shares of Common Stock as is determined
by dividing (i) the  outstanding  amount of principal and interest due under the
Note by (ii) the  unweighted  average of the  closing  sale prices of the Common
Stock on the Nasdaq National Market for such twenty trading days.

          (b) In the event of a mandatory  exchange  pursuant to this Section 5,
the holder of this Note shall  surrender,  as soon as practicable  after Arch or
the Issuer or both gives LGS notice of such mandatory exchange, this Note to the
Issuer and shall  thereafter  receive  certificates  for the number of shares of
Common  Stock to which such  holder is entitled  pursuant to this  Section 5. As
soon as practicable  after such surrender of the Note, the Issuer shall cause to
be issued and  delivered  to such  holder,  or on his or its  written  order,  a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable on such exchange in accordance with the provisions hereof.

          (c) No  fractional  shares of Common Stock shall be issued in exchange
of this  Note.  In lieu of any  fractional  shares  to which  the  holder  would
otherwise  be  entitled,  the  Issuer  shall pay cash in an amount  equal to the
product of (i) such  fraction,  and (ii) the  unweighted  average of the closing
sale prices of the Common Stock on the Nasdaq  National  Market for the last ten
days of the twenty day period described in Section 5(a) above.

     6. MODIFICATION OF PAYMENT TERMS UPON TRANSFER TO GUARANTOR.

          In the event that Arch  Communications  Group, Inc. (the "Guarantor"),
or its  nominee,  becomes the holder of this Note  pursuant to the terms of that
certain Guaranty,  of even date herewith,  by the Guarantor in favor of LGS, the
terms of this Note shall be modified as follows:

          (a) The rate of interest  provided in Section  1(a) shall be increased
from twelve percent (12%) per annum to fourteen and one-half (14.5%) percent per
annum.

          (b) All principal and interest due hereunder  shall be payable in cash
on the Maturity Date. As used herein, "Maturity Date" shall mean the earliest of
the following events: (i) the sale of a controlling interest in the Issuer; (ii)
a sale of a substantial part of the assets of the Issuer;  (iii) the termination
of the Management Agreement dated as of October 1, 1995, as amended, between The
Westlink Company ("Westlink") and the Issuer (the "Management


<PAGE>

Agreement")  by Westlink due to (x) a  substantial  and  material  breach of the
Management  Agreement by the Issuer which has not been cured within  thirty (30)
days of the Issuer's receipt of written notice of such breach from Westlink, (y)
the  insolvency or  bankruptcy of the Issuer or (z) the  occurrence of any other
event that  materially  impacts the Issuer's  ability to perform its obligations
under  the  Management  Agreement;  or (iv)  any date on which  the  Issuer  has
Available  Cash (as  defined  below),  but only to the extent of such  Available
Cash.  "Available  Cash" shall mean cash  available  after  payment of operating
expenses  (including salary and benefits under the Employment  Agreement between
the Issuer and June E. Walsh),  interest,  taxes, principal and debt repayments,
and capital  expenditures  described in the  Shareholders  Agreement dated as of
September  23, 1994, as amended,  among the Issuer,  Westlink and June E. Walsh,
the Business  Plan adopted by the Issuer  and/or in the duly adopted  budgets of
the Issuer.

          (c) Sections 1(b),  1(c),  3(a), 3(b), 4 and 5 shall be deemed deleted
in their  entirety and all  references to "Arch" in Sections  2(3),  (4) and (5)
shall be deleted (provided,  however, that Issuer shall have the right to prepay
its  obligations  hereunder,  in whole or in part,  in cash, at any time without
penalty).

                                                                  EXHIBIT 99.9
                                    GUARANTY


     To induce  Adelphia  Communications  Corporation,  a  Delaware  corporation
("Adelphia"),  to sell to Benbow PCS Ventures,  Inc.  (the  "Buyer")  Adelphia's
stock in Page Call,  Inc.  ("Page Call") pursuant to that certain Stock Purchase
Agreement dated April 30, 1997, as amended,  in exchange for, INTER ALIA, shares
of the Buyer's Series A Redeemable  Preferred  shares,  no par value,  with such
rights, preferences and privileges as described in EXHIBIT A hereto (the "Benbow
Preferred Stock"),  the undersigned Arch  Communications  Group, Inc. ("Arch" or
the  "Guarantor")  hereby  guarantees to Adelphia the payment and performance by
the Buyer of all  Buyer's  obligations  (the  "Obligations")  under  the  Benbow
Preferred Stock and under the Exchange Agreement of even date herewith,  between
Adelphia  and  Buyer  (the  "Exchange  Agreement")  which  Obligations  shall be
determined  without  regard to Buyer's  inability  to  perform  under the Benbow
Preferred Stock or under the Exchange Agreement because of restrictions  imposed
by applicable law or for any other reason.

     The Guarantor also agrees:  that this Guaranty shall not be impaired by any
modification, supplement, extension or amendment of any contract or agreement to
which the parties thereto may hereafter agree, nor by any modification,  release
or  other  alteration  of any of the  obligations  hereby  guaranteed  or of any
security  therefor,  nor by any  agreements  or  arrangements  whatever with the
holders of the Benbow  Preferred  Stock (the  "Holders")  or anyone  else;  that
Guarantor shall not be relieved or released of any of its obligations  hereunder
by reason of the  inability or failure of the Buyer to perform  under the Benbow
Preferred Stock or under the Exchange Agreement because of restrictions  imposed
by applicable  law; that the liability of the Guarantor  hereunder is direct and
unconditional  and may be enforced without requiring the Holders first to resort
to any other right,  remedy or security;  that the Guarantor  shall not have any
right of subrogation,  reimbursement or indemnity  whatsoever,  unless and until
all of the  Obligations of the Buyer have been paid and performed in full;  that
if the Buyer or any  Guarantor  should at any time  become  insolvent  or make a
general  assignment,  or if a  petition  in  bankruptcy  or  any  insolvency  or
reorganization  proceedings  shall  be filed or  commenced  by the  Buyer or the
Guarantor,  any and all  obligations  of Guarantor  shall,  at the option of the
Holders,  forthwith  become due and payable without  notice;  that if, after the
expiration  of  30  days  after  a  petition  in  bankruptcy  or  insolvency  or
reorganization   proceedings  shall  be  commenced  against  the  Buyer  or  the
Guarantor,  any and all  obligations  of the  Guarantor  shall,  at the Holders'
option, forthwith become due and payable without notice; that this Guaranty is a
continuing Guaranty which shall remain effective while any of the obligations of
the Buyer under the Benbow  Preferred  Stock or the Exchange  Agreement shall be
outstanding;  that this  Guaranty is a  continuing  Guaranty  which shall remain
effective  during  the  term of the  Benbow  Preferred  Stock  and the  Exchange
Agreement;  that  nothing  shall  discharge  or  satisfy  the  liability  of the
Guarantor  hereunder  except  the full  payment  and  performance  of all of the
Buyer's obligations to the Holders as provided in the Benbow Preferred Stock and
the  Exchange  Agreement;  that  any  and  all  present  and  future  debts  and
obligations  of the Buyer to the  Guarantor  are hereby  waived and postponed in
favor of and subordinated to the full payment and performance of all present and
future debts and obligations of the Buyer to the Holders.

<PAGE>

     In the event and each time that the  Buyer  becomes  obligated  to  deliver
shares of Common  Stock to the holder or holders of the Benbow  Preferred  Stock
shares in exchange for Benbow  Preferred  Stock,  subject to the  conditions set
forth herein,  and further  subject to the  conditions set forth in Articles III
and IV of the Loan  Agreement  (the "Loan  Agreement") of even date by and among
the Guarantor,  The Westlink Company II ("Westlink")  and the Buyer,  Arch shall
issue such Common  Stock and  contribute  such  Common  Stock to  Westlink,  and
Westlink  shall  transfer such Common Stock to the Buyer.  In the event that (i)
the  conditions  set forth in Articles III and IV of the Loan Agreement have not
been met and the Guarantor has not waived  compliance with such  conditions,  or
(ii)  Westlink  is in breach  of,  or fails to give  adequate  assurance  to the
Guarantor of, the performance of its obligations under the previous sentence, or
(iii) the Guarantor  otherwise  determines in its sole discretion to do so, then
the Guarantor  shall instead  issue such shares  directly to Adelphia.  All such
shares of Common Stock shall be fully paid, nonassessable and free of preemptive
rights.

     Adelphia  represents,  warrants and covenants as follows:  The Common Stock
transferred  to Adelphia as  described  above shall be acquired by Adelphia  not
with a view to or in connection  with any resale or  distribution.  Adelphia has
had such opportunity as it has deemed adequate to obtain from the Guarantor such
information as is necessary to permit  Adelphia to evaluate the merits and risks
of its acquisition of the Common Stock.  Without  limiting the generality of the
foregoing,   Adelphia   acknowledges  that  the  Guarantor  is  subject  to  the
informational  requirements of the Securities  Exchange Act of 1934, as amended,
and,  in  accordance  therewith,  files  reports,  proxy  statements  and  other
information with the Securities and Exchange  Commission.  Subject to the rights
provided to Adelphia pursuant to the Registration  Rights Agreement of even date
herewith,  Adelphia understands that the Common Stock transferred to Adelphia as
described  above will not be registered  under the securities laws of the United
States or any other  jurisdiction  and cannot be transferred or resold except as
permitted pursuant to a valid registration  statement or an applicable exemption
from  registration.  Each time  Adelphia  acquires  shares  of  Common  Stock as
described above, Adelphia shall be deemed to have reaffirmed,  as of the date of
such  acquisition,   the  representations  made  in  this  paragraph.   Adelphia
understands  that the  certificate  representing  the Common  Stock shall bear a
legend substantially in the following form:

          "The securities  represented by this  certificate  have
          not been  registered  under the Securities Act of 1933,
          as   amended,   and   may  not  be   sold,   exchanged,
          transferred,   pledged,   hypothecated   or   otherwise
          disposed  of  except  pursuant  to  registration  or an
          available   exemption  from   registration   under  the
          Securities Act of 1933."

     So long as any  Benbow  Preferred  Stock is  issued  and  outstanding,  the
Guarantor  shall  reserve and maintain a  sufficient  number of shares of Common
Stock  for  issuance  and  delivery  upon  exchange  of all  outstanding  Benbow
Preferred  Stock.  Upon the  occurrence  of each and every  event  requiring  an
adjustment in a Base Price (as defined in Section 3 of the Exchange  Agreement),
Arch shall provide such notice and information to Benbow as may be reasonably


<PAGE>

required in order to enable  Benbow to provide a  certificate  of  adjustment to
each  holder  of  Benbow   Preferred  Stock  in  the  manner  and  time  periods
contemplated by Section 3(vi) of the Exchange Agreement.

     Adelphia,  and any  subsequent  holder  of the  Benbow  Preferred  Stock by
asserting any claim under the Guaranty, confirm and agree that the Guarantor may
condition its payment and performance  obligations  under this Guaranty upon the
simultaneous sale,  transfer and assignment of all of the Benbow Preferred Stock
to Guarantor, or its nominee, without recourse or representation,  other than as
to good title and the absence of liens or encumbrances.

     The Guarantor  shall, as a condition to any  consolidation or merger of the
Guarantor with or into another corporation,  or the sale of all or substantially
all of the assets of the Guarantor to another  corporation,  execute and deliver
such documents and take such actions (including without limitation obtaining the
written  consent of any  corporation  with which the Guarantor  consolidates  or
merges  or  which  purchases  all or  substantially  all of  the  assets  of the
Guarantor)  as may be  reasonably  necessary to  effectuate  the  provisions  of
Section 3(v) of the Exchange Agreement.

     The Guarantor waives: notice of acceptance hereof,  presentment and protest
of any  instrument,  and notice  thereof;  notice of default;  all  diligence in
collection or protection or  realization  upon the  obligations  due to Adelphia
from Buyer;  and all other notices to which such  Guarantor  might  otherwise be
entitled.

     This Guaranty shall continue to be effective, or be reinstated, as the case
may be, if at any time payment,  or any part thereof,  of any of the obligations
of the Buyer to Adelphia is rescinded or must  otherwise be restored or returned
by  Adelphia  upon  the  insolvency,  bankruptcy,  dissolution,  liquidation  or
reorganization  of the  Buyer or the  Guarantor,  or upon or as a result  of the
appointment  of a receiver  or trustee or similar  officer  for the Buyer or the
Guarantor or any substantial part of their respective properties,  or otherwise,
all as though such payments had not been made.

     Guarantor  shall pay all costs of  collection of this  Guaranty,  including
without limitation, reasonable attorneys' fees and expenses should this Guaranty
be collected by or through an attorney-at-law.

     This  Guaranty,  all acts and  transactions  hereunder,  and the rights and
obligations of the parties hereto shall be governed,  construed and  interpreted
according  to the laws of the State of  California,  shall be  binding  upon and
shall inure to the benefit of their respective heirs, executors, administrators,
successors and assigns.

                                    GUARANTY


     To induce Lisa-Gaye  Shearing ("LGS") to sell to Benbow PCS Ventures,  Inc.
(the  "Buyer")  her stock in Page Call,  Inc.  ("Page  Call")  pursuant  to that
certain Stock Purchase  Agreement dated April 30, 1997, as amended,  in exchange
for, INTER ALIA, a certain  Promissory  Note dated the date hereof in the amount
of Two Hundred Eighty-Five Thousand and Fifteen Dollars ($285,015) (the "Note"),
the  undersigned  Arch  Communications  Group,  Inc.  (the  "Guarantor")  hereby
guarantees  to LGS (a)  the  payment  by the  Buyer  of all  sums  which  may be
presently due and owing and of all sums which shall in the future become due and
owing to LGS  under  the Note;  (b) the due  performance  by Buyer of all of the
Buyer's  obligations  under said Note;  and (c) the  payment by the Buyer of all
sums which may be presently due and owing and all sums which shall in the future
become due and owing by the Buyer to LGS under the Consulting  Agreement of even
date  herewith  between  the  Buyer  and  LGS,  as  the  same  may  be  amended,
supplemented or modified from time to time (the "Consulting Agreement").

     The Guarantor also agrees:  that this Guaranty shall not be impaired by any
modification, supplement, extension or amendment of any contract or agreement to
which the parties thereto may hereafter agree, nor by any modification,  release
or  other  alteration  of any of the  obligations  hereby  guaranteed  or of any
security  therefor,  nor by any agreements or arrangements  whatever with LGS or
anyone  else;  that the  liability  of the  Guarantor  hereunder  is direct  and
unconditional  and may be enforced without  requiring LGS first to resort to any
other right, remedy or security;  that the Guarantor shall not have any right of
subrogation,  reimbursement or indemnity whatsoever, unless and until all of the
debts and  obligations  of the  Buyer to LGS  under the Note and the  Consulting
Agreement have been paid in full;  that if the Buyer or any Guarantor  should at
any time  become  insolvent  or make a general  assignment,  or if a petition in
bankruptcy or any  insolvency or  reorganization  proceedings  shall be filed or
commenced by the Buyer or the  Guarantor,  any and all  obligations of Guarantor
shall, at LGS's option,  forthwith  become due and payable without notice;  that
if, after the expiration of 30 days after a petition in bankruptcy or insolvency
or  reorganization  proceedings  shall be  commenced  against  the  Buyer or the
Guarantor, any and all obligations of the Guarantor shall, at the option of LGS,
forthwith  become  due and  payable  without  notice;  that this  Guaranty  is a
continuing Guaranty which shall remain effective while any of the obligations of
the Buyer under the Note and the Consulting Agreement shall be outstanding; that
this Guaranty is a continuing  Guaranty which shall remain  effective during the
term of the Note and the Consulting  Agreement;  that nothing shall discharge or
satisfy the  liability of the  Guarantor  hereunder  except the full payment and
performance  of all of the Buyer's debts and  obligations  to LGS as provided in
the Note and the Consulting Agreement; that any and all present and future debts
and obligations of the Buyer to the Guarantor are hereby waived and postponed in
favor of and subordinated to the full payment and performance of all present and
future debts and obligations of the Buyer to LGS.

<PAGE>

The Guarantor shall have the right, at its sole option,  to make any payments of
interest and principal due under the Note as follows:

          (i) in cash; or

          (ii) in such number of shares of common stock (the "Common  Stock") of
          the Guarantor as is determined under Sections 1(b)(ii),  4 or 5 of the
          Note, as applicable; or

          (iii) in a combination of cash and Common Stock as provided above.

     In the event and each time that the  Buyer  becomes  obligated  to  deliver
shares of the  Common  Stock to LGS in  exchange  for the Note,  subject  to the
conditions set forth herein,  and further subject to the conditions set forth in
Articles III and IV of the Loan Agreement (the "Loan Agreement") of even date by
and among the Guarantor,  The Westlink  Company II  ("Westlink")  and the Buyer,
then the  Guarantor  shall issue such Common  Stock and  contribute  such Common
Stock to Westlink,  and Westlink  shall transfer such Common Stock to the Buyer.
In the event that (i) the  conditions  set forth in  Articles  III and IV of the
Loan  Agreement  have not been met and the Guarantor  has not waived  compliance
with  such  conditions,  or (ii)  Westlink  is in  breach  of,  or fails to give
adequate assurance to the Guarantor of, the performance of its obligations under
the previous sentence,  or (iii) the Guarantor otherwise  determines in its sole
discretion to do so, then the Guarantor shall instead issue such shares directly
to LGS. All such shares of Common Stock shall be fully paid,  nonassessable  and
free of preemptive rights.

     LGS  represents,  warrants  and  covenants  as  follows:  The Common  Stock
transferred  to LGS as described  above shall be acquired by LGS not with a view
to  or in  connection  with  any  resale  or  distribution.  LGS  has  had  such
opportunity  as she has  deemed  adequate  to  obtain  from the  Guarantor  such
information  as is  necessary  to permit LGS to evaluate the merits and risks of
her  acquisition  of  Common  Stock.  Without  limiting  the  generality  of the
foregoing,  LGS acknowledges  that the Guarantor is subject to the informational
requirements  of the  Securities  Exchange  Act of 1934,  as  amended,  and,  in
accordance therewith, files reports, proxy statements and other information with
the Securities and Exchange  Commission.  LGS understands  that the Common Stock
transferred  to  LGS  as  described  above  will  not be  registered  under  the
securities  laws of the United  States or any other  jurisdiction  and cannot be
transferred  or resold  except as  permitted  pursuant  to a valid  registration
statement or an applicable  exemption from registration.  Each time LGS acquires
shares  of  Common  Stock  as  described  above,  LGS  shall be  deemed  to have
reaffirmed, as of the date of such acquisition, the representations made in this
paragraph.  Subject to the rights  provided to LGS pursuant to the  Registration
Rights  Agreement of even date herewith,  LGS  understands  that the certificate
representing the Common Stock shall bear a legend substantially in the following
form:


<PAGE>

          "The securities  represented by this  certificate  have
          not been  registered  under the Securities Act of 1933,
          as   amended,   and   may  not  be   sold,   exchanged,
          transferred,   pledged,   hypothecated   or   otherwise
          disposed  of  except  pursuant  to  registration  or an
          available   exemption  from   registration   under  the
          Securities Act of 1933."

     So long as the Note is issued and outstanding,  the Guarantor shall reserve
and  maintain a  sufficient  number of shares of Common  Stock for  issuance and
delivery upon exchange of the Note.

     LGS, and any  subsequent  holder of the Note by  asserting  any claim under
this  Guaranty  with respect to the Note,  confirm and agree that  Guarantor may
condition  its payment and  performance  obligations  under this  Guaranty  with
respect to such Note upon the simultaneous sale, transfer and assignment of such
Note (or, if the holder of this Note does not receive  payment  with  respect to
such  Note,  from  the  Guarantor  or  otherwise,  in an  amount  equal  to  all
obligations due and payable to the holder under the Note, by the assignment of a
participation  therein in an amount equal to all amounts  paid by the  Guarantor
under the  Guaranty  with  respect  to the Note) to  Guarantor  or its  nominee,
without recourse or representation,  other than as to good title and the absence
of liens or encumbrances.

     The Guarantor waives: notice of acceptance hereof,  presentment and protest
of any  instrument,  and notice  thereof;  notice of default;  all  diligence in
collection or protection or  realization  upon the  obligations  due to LGS from
Buyer;  and all  other  notices  to which  such  Guarantor  might  otherwise  be
entitled.

     This Guaranty shall continue to be effective, or be reinstated, as the case
may be, if at any time payment,  or any part thereof,  of any of the obligations
of the Buyer to LGS is  rescinded  or must  otherwise be restored or returned by
LGS upon the insolvency, bankruptcy, dissolution,  liquidation or reorganization
of the Buyer or the  Guarantor,  or upon or as a result of the  appointment of a
receiver  or trustee or similar  officer for the Buyer or the  Guarantor  or any
substantial part of their  respective  properties,  or otherwise,  all as though
such payments had not been made.

     Guarantor  shall pay all costs of  collection of this  Guaranty,  including
without limitation, reasonable attorneys' fees and expenses should this Guaranty
be collected by or through an attorney-at-law.

     This  Guaranty,  all acts and  transactions  hereunder,  and the rights and
obligations of the parties hereto shall be governed,  construed and  interpreted
according  to the laws of the State of  California,  shall be  binding  upon and
shall inure to the benefit of their respective heirs, executors, administrators,
successors and assigns.

                         ARCH COMMUNICATIONS GROUP, INC.

                          REGISTRATION RIGHTS AGREEMENT

Arch  Communications  Group,  Inc.,  a  Delaware  corporation  (the  "Company"),
Adelphia Communications  Corporation,  a Delaware corporation ("Adelphia"),  and
Lisa-Gaye Shearing ("Shearing")  (Adelphia and Shearing together are referred to
herein as the "Selling Stockholders").

     WHEREAS, pursuant to a Stock Purchase Agreement, dated as of April 30, 1997
and  amended as of June 29,  1998,  the Selling  Stockholders  agreed to sell to
Benbow PCS  Ventures,  Inc., a  California  corporation  ("Benbow"),  and Benbow

and (ii) Benbow  agreed to issue to Shearing a  promissory  note in the original
principal amount of $285,015,  exchangeable in certain  circumstances for Common

     WHEREAS,  the Company has  guaranteed  the  obligations of Benbow under the
Preferred  Shares and the Note pursuant to Guaranties of even date herewith (the
"Guaranties");

     WHEREAS,  the Company and the  Selling  Stockholders  desire to provide for
certain arrangements with respect to the registration of shares of capital stock
of the Company under the Securities Act of 1933;

     NOW,  THEREFORE,  in  consideration  of the mutual  promises and  covenants
contained in this Agreement, the parties hereto agree as follows:

     1. CERTAIN  DEFINITIONS.  As used in this  Agreement,  the following  terms
shall have the following respective meanings:

          "COMMISSION"  means the  Securities  and Exchange  Commission,  or any
other Federal agency at the time administering the Securities Act.

          "COMMON  STOCK" means the common stock,  $.01 par value per share,  of
the Company.


<PAGE>

          "EXCHANGE ACT" means the Securities  Exchange Act of 1934, as amended,
or any similar Federal statute,  and the rules and regulations of the Commission
issued under such Act, as they each may, from time to time, be in effect.

          "REGISTRABLE  SHARES"  means (i) the shares of Common  Stock issued or
issuable  upon  conversion  or  exchange  of the Note  (whether  pursuant to the
Guaranties  or  otherwise),  (ii) the shares of Common  Stock issued or issuable
upon  conversion or exchange of the Preferred  Shares  (whether  pursuant to the
Guaranties  or  otherwise)  and (iii) any other shares of Common Stock issued in
respect  of  such   shares   (because   of  stock   splits,   stock   dividends,
reclassifications,  recapitalizations,  or similar events);  PROVIDED,  HOWEVER,
that  shares of Common  Stock  which are  Registrable  Shares  shall cease to be
Registrable  Shares (i) upon any sale  pursuant to a  Registration  Statement or
Rule 144  under  the  Securities  Act or (ii)  upon any sale in any  manner to a
person  or entity  which,  by virtue of  Section  13 of this  Agreement,  is not
entitled to the rights provided by this Agreement.

          "REGISTRATION EXPENSES" means the expenses described in Section 5.

successors, or any other form for a similar limited purpose, or any registration
statement  covering  only  securities  proposed  to be  issued in  exchange  for
securities or assets of another  corporation,  or any registration  filed at the
request of other stockholders of the Company).

          "SECURITIES ACT" means the Securities Act of 1933, as amended,  or any
similar Federal statute,  and the rules and regulations of the Commission issued
under such Act, as they each may, from time to time, be in effect.

          "STOCKHOLDERS"  means the  Selling  Stockholders  and any  persons  or
entities to whom the rights granted under this Agreement are  transferred by any
Selling Stockholders, their successors or assigns pursuant to Section 13 hereof.

     2. REQUIRED REGISTRATION.

          (a) At any  time,  a  Stockholder  or  Stockholders  may  request  the
Company,  in writing,  to effect the  registration on Form S-3 (or any successor
form relating to secondary  offerings) of all or any portion of the  Registrable
Shares.  If the holders  initiating  the  registration  intend to distribute the
Registrable Shares by means of an underwriting, they shall so advise the Company
in their request and shall include the identity of the proposed  underwriter who
shall be  acceptable  to the  Company.  Upon  receipt of any such  request,  the
Company shall promptly give written notice of such proposed  registration to all
other  Stockholders.  Such Stockholders  shall have the right, by giving written
notice to the Company within 10 days after the Company  provides its notice,  to
elect to have included in such registration such of their Registrable  Shares as
such  Stockholders may request in such notice of election;  provided that if the
underwriter (if any) managing the offering determines that, because of marketing
factors, all of the Registrable

<PAGE>

Shares requested to be registered by all Stockholders may not be included in the
offering,   then  all  Stockholders  who  have  requested   registration   shall
participate  in the  registration  pro rata based upon the number of Registrable
Shares which they have  requested to be so  registered.  Thereupon,  the Company
shall,  as  expeditiously  as  possible,  use its best  efforts  to  effect  the
registration  on Form S-3 (or such  successor  form) of all  Registrable  Shares
which the Company has been requested to so register.

          (b) The  Company  shall  only be  required  to  effect  a total of two
registrations  pursuant to paragraph (a) above.  In addition,  the Company shall
not be required to effect any registration within six months after the effective
date of any other Registration Statement of the Company.

          (c) If at the  time of any  request  to  register  Registrable  Shares
pursuant to this  Section 2, the Company is engaged or has fixed plans to engage
within 90 days of the time of the request in a registered  public offering as to
which the Stockholders may include  Registrable  Shares pursuant to Section 3 or
is engaged in any other activity which, in the good faith  determination  of the
Company's  Board of  Directors,  would be materially  adversely  affected by the
requested  registration  to the  material  detriment  of the  Company,  then the
Company may at its option  direct that such  request be delayed for a period not
in excess of six months from the effective  date of such offering or the date of
commencement of such other material activity,  as the case may be. Following the
delay of the filing of a  registration  statement in accordance  with the above,
the  Company  shall  promptly  proceed  with such  filing at the  earliest  time
practicable,  notwithstanding  such  six-month  period  has  not  run,  if  such
registered public offering is abandoned by the Company or such adverse effect on
such other activity is no longer present.

     3. INCIDENTAL REGISTRATION.

          (a) Whenever  the Company  proposes to file a  Registration  Statement
(other than  pursuant to Section 2) at any time and from time to time,  it will,
prior to such filing,  give written notice to all  Stockholders of its intention
to do so and, upon the written  request of a Stockholder or  Stockholders  given
within 10 days after the Company provides such notice (which request shall state
the intended  method of disposition  of such  Registrable  Shares),  the Company
shall use its best efforts to cause all Registrable Shares which the Company has
been requested by such  Stockholder or Stockholders to register to be registered
under the Securities  Act to the extent  necessary to permit their sale or other
disposition in accordance with the intended methods of distribution specified in
the request of such Stockholder or Stockholders; provided that the Company shall
have the right to postpone or withdraw  any  registration  effected  pursuant to
this Section 3 without obligation to any Stockholder.

          (b) In connection with any registration under this Section 3 involving
an  underwriting,  the Company shall not be required to include any  Registrable
Shares in such  registration  unless the holders thereof accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it (provided that such terms must be consistent with this Agreement).  If in the
opinion of the  managing  underwriter  it is  appropriate  because of  marketing
factors to limit the number of shares of Common Stock to be included in

<PAGE>

the offering,  then the Company and the Stockholders shall reduce, on a pro rata
basis,  the number of shares each intends to include in the registration so that
the aggregate  number to be  registered  shall equal that number of shares which
the managing  underwriter  believes should be included therein. If the number of
Registrable  Shares  to be  included  in the  offering  in  accordance  with the
foregoing  is less  than the  total  number  of  shares  which  the  holders  of
Registrable  Shares  have  requested  to  be  included,   then  the  holders  of
Registrable  Shares  who  have  requested  registration  and  other  holders  of
securities  entitled to include them in such  registration  shall participate in
the  registration  pro rata based upon their total ownership of shares of Common
Stock  (giving  effect to the  conversion  into Common  Stock of all  securities
convertible  thereinto  and the  exchange  for  Common  Stock of all  securities
exchangeable  therefor).  If any holder  would thus be entitled to include  more
securities  than such holder  requested  to be  registered,  the excess shall be
allocated among other requesting holders pro rata in the manner described in the
preceding sentence.

     4. REGISTRATION PROCEDURES.  If and whenever the Company is required by the
provisions of this Agreement to use its best efforts to effect the  registration
of any of the Registrable Shares under the Securities Act, the Company shall:

          (a) file with the Commission a Registration  Statement with respect to
such  Registrable  Shares and use its best  efforts  to cause that  Registration
Statement to become and remain effective;

          (b) as  expeditiously as possible prepare and file with the Commission
any amendments and supplements to the Registration  Statement and the prospectus
included  in the  Registration  Statement  as  may  be  necessary  to  keep  the
Registration Statement effective,  in the case of a firm commitment underwritten
public  offering,  until each  underwriter has completed the distribution of all
securities  purchased  by it and, in the case of any other  offering,  until the
earlier of the sale of all Registrable  Shares covered thereby or 120 days after
the effective date thereof;

          (c) as expeditiously  as possible furnish to each selling  Stockholder
such  reasonable  numbers of copies of the  prospectus,  including a preliminary
prospectus,  in conformity with the requirements of the Securities Act, and such
other documents as the selling  Stockholder  may reasonably  request in order to
facilitate the public sale or other disposition of the Registrable  Shares owned
by the selling Stockholder; and

          (d) as  expeditiously  as possible use its best efforts to register or
qualify the Registrable  Shares covered by the Registration  Statement under the
securities  or Blue Sky laws of such  states as the selling  Stockholders  shall
reasonably  request,  and do any and all  other  acts  and  things  that  may be
necessary or  desirable to enable the selling  Stockholders  to  consummate  the
public sale or other disposition in such states of the Registrable  Shares owned
by the selling  Stockholder;  PROVIDED,  HOWEVER,  that the Company shall not be
required  in  connection  with  this  paragraph  (d)  to  qualify  as a  foreign
corporation  or  execute  a  general  consent  to  service  of  process  in  any
jurisdiction.


<PAGE>

     If the Company  has  delivered  preliminary  or final  prospectuses  to the
selling  Stockholders  and after  having  done so the  prospectus  is amended to
comply with the  requirements  of the Securities Act, the Company shall promptly
notify the selling  Stockholders  and, if  requested,  the selling  Stockholders
shall  immediately  cease  making  offers of  Registrable  Shares and return all
prospectuses  to the Company.  The Company  shall  promptly  provide the selling
Stockholders  with revised  prospectuses  and,  following receipt of the revised
prospectuses,  the selling Stockholders shall be free to resume making offers of
the Registrable Shares.

     5. ALLOCATION OF EXPENSES.  The Company will pay all Registration  Expenses
of all registrations  under this Agreement.  For purposes of this Section 5, the
term "Registration  Expenses" shall mean all expenses incurred by the Company in
complying with this Agreement,  including,  without limitation, all registration
and filing fees, exchange listing fees, printing expenses,  fees and expenses of
counsel for the Company,  state Blue Sky fees and  expenses,  and the expense of
any  special  audits  incident  to or  required  by any such  registration,  but
excluding underwriting discounts,  selling commissions and the fees and expenses
of selling Stockholders' own counsel.

     6. INDEMNIFICATION AND CONTRIBUTION.

          (a) In the event of any registration of any of the Registrable  Shares
under the Securities Act pursuant to this Agreement,  the Company will indemnify
and hold harmless the seller of such  Registrable  Shares,  each  underwriter of
such Registrable Shares, and each other person, if any, who controls such seller
or  underwriter  within the meaning of the  Securities  Act or the  Exchange Act
against any losses, claims,  damages or liabilities,  joint or several, to which
such seller,  underwriter  or  controlling  person may become  subject under the
Securities  Act,  the  Exchange  Act,  state  securities  or  Blue  Sky  laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement of any material fact contained in any  Registration  Statement
under which such  Registrable  Shares were registered  under the Securities Act,
any preliminary  prospectus or final  prospectus  contained in the  Registration
Statement,  or any amendment or supplement to such  Registration  Statement,  or
arise out of or are based  upon the  omission  or  alleged  omission  to state a
material fact required to be stated  therein or necessary to make the statements
therein not misleading;  and the Company will reimburse such seller, underwriter
and each such controlling person for any legal or any other expenses  reasonably
incurred by such seller,  underwriter or controlling  person in connection  with
investigating or defending any such loss,  claim,  damage,  liability or action;
PROVIDED,  HOWEVER,  that the Company will not be liable in any such case to the
extent that any such loss, claim,  damage or liability arises out of or is based
upon any untrue  statement  or  omission  made in such  Registration  Statement,
preliminary prospectus or final prospectus, or any such amendment or supplement,
in reliance upon and in conformity with information furnished to the Company, in
writing,  by or on behalf of such  seller,  underwriter  or  controlling  person
specifically for use in the preparation thereof.

<PAGE>

          (b) In the event of any registration of any of the Registrable  Shares
under the Securities Act pursuant to this Agreement,  each seller of Registrable
Shares, severally and not jointly, will indemnify and hold harmless the Company,
each of its  directors  and  officers  and  each  underwriter  (if any) and each
person,  if any,  who controls  the Company or any such  underwriter  within the
meaning of the Securities Act or the Exchange Act,  against any losses,  claims,
damages or liabilities,  joint or several, to which the Company,  such directors
and officers,  underwriter  or  controlling  person may become subject under the
Securities  Act,  Exchange Act, state  securities or Blue Sky laws or otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise out of or are based upon any untrue  statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such   Registrable   Shares  were  registered  under  the  Securities  Act,  any
preliminary  prospectus  or  final  prospectus  contained  in  the  Registration
Statement,  or any  amendment or supplement to the  Registration  Statement,  or
arise out of or are based  upon any  omission  or  alleged  omission  to state a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  if the statement or omission was made in reliance upon
and in conformity with information  relating to such seller furnished in writing
to the Company by or on behalf of such seller specifically for use in connection
with the preparation of such Registration  Statement,  prospectus,  amendment or
supplement;  PROVIDED,  HOWEVER,  that  the  obligations  of  such  Stockholders
hereunder  shall  be  limited  to an  amount  equal  to  the  proceeds  to  each
Stockholder of Registrable Shares sold in connection with such registration.

          (c) Each party entitled to  indemnification  under this Section 6 (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom;  PROVIDED,  that counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval  shall not be  unreasonably
withheld); and, PROVIDED,  FURTHER, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the  Indemnifying  Party of its
obligations  under this Section 6. The Indemnified Party may participate in such
defense at such party's expense; PROVIDED,  however, that the Indemnifying Party
shall  pay such  expense  if  representation  of such  Indemnified  Party by the
counsel retained by the Indemnifying  Party would be inappropriate due to actual
or potential  differing  interests  between the Indemnified  Party and any other
party represented by such counsel in such proceeding.  No Indemnifying Party, in
the defense of any such claim or  litigation  shall,  except with the consent of
each  Indemnified  Party,  consent  to entry of any  judgment  or enter into any
settlement which does not include as an unconditional term thereof the giving by
the  claimant  or  plaintiff  to such  Indemnified  Party of a release  from all
liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation  without the
prior written consent of the Indemnifying Party.

          (d) In order to provide for just and equitable  contribution  to joint
liability under the Securities Act in any case in which either (i) any holder of
Registrable  Shares exercising  rights under this Agreement,  or any controlling
person of any such holder,  makes a claim for  indemnification  pursuant to this
Section 6 but it is judicially  determined  (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such  indemnification may not be
enforced in such case  notwithstanding the fact that this Section 6 provides for
indemnification  in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling  Stockholder or any such controlling
person in circumstances for which indemnification is provided under this Section
6; then, in each such case, the Company and such  Stockholder will contribute to
the  aggregate  losses,  claims,  damages  or  liabilities  to which they may be
subject (after contribution from others) in such proportions so that such holder
is responsible  for the portion  represented  by the percentage  that the public
offering price of its Registrable  Shares offered by the Registration  Statement
bears  to  the  public  offering  price  of  all  securities   offered  by  such
Registration  Statement,  and the  Company  is  responsible  for  the  remaining
portion;  PROVIDED,  HOWEVER, that, in any such case, (A) no such holder will be
required  to  contribute  any  amount  in excess  of the  proceeds  to it of all
Registrable Shares sold by it pursuant to such Registration  Statement,  and (B)
no person or entity guilty of fraudulent  misrepresentation,  within the meaning
of Section 11(f) of the Securities Act, shall be entitled to  contribution  from
any person or entity who is not guilty of such fraudulent misrepresentation.

     7. INDEMNIFICATION WITH RESPECT TO UNDERWRITTEN OFFERING. In the event that
Registrable  Shares  are  sold  pursuant  to  a  Registration  Statement  in  an
underwritten offering pursuant to Section 2, the Company agrees to enter into an
underwriting agreement containing customary  representations and warranties with
respect to the  business and  operations  of an issuer of the  securities  being
registered  and  customary  covenants  and  agreements  to be  performed by such
issuer,  including  without  limitation  customary  provisions  with  respect to
indemnification by the Company of the underwriters of such offering.

     8. INFORMATION BY HOLDER. Each Stockholder  including Registrable Shares in
any registration  shall furnish to the Company such  information  regarding such
Stockholder and the distribution proposed by such Stockholder as the Company may
reasonably  request in writing and as shall be required in  connection  with any
registration, qualification or compliance referred to in this Agreement.

     9. "STAND-OFF" AGREEMENT. Each Stockholder, if requested by the Company and
the managing  underwriter of an offering by the Company of Common Stock or other
securities of the Company pursuant to a Registration Statement, shall agree not,
without the consent of such managing underwriter,  to sell publicly or otherwise
transfer or dispose of any Registrable Shares or other securities of the Company
held by such Stockholder for a specified period of time (not to exceed 120 days)
following the effective date of such Registration Statement;  PROVIDED, that all
Stockholders  holding not less than the number of shares of Common Stock held by
such Stockholder (including shares of Common Stock issuable upon the exchange of
Preferred  Shares,  or other  securities  convertible  into or exchangeable  for
Common Stock, or upon the exercise of

<PAGE>

options,  warrants or rights) and all  executive  officers and  directors of the
Company enter into similar agreements.

A.  10.  RULE  144  REQUIREMENTS.   The  Company  agrees  to:  comply  with  the
requirements  of Rule 144(c)  under the  Securities  Act with respect to current
public  information  about the  Company;  use its best  efforts to file with the
Commission  in a timely manner all reports and other  documents  required of the
Company under the Securities Act and the Exchange Act; and furnish to any holder
of Registrable  Shares upon request (i) a written statement by the Company as to
its  compliance  with the  requirements  of said Rule 144(c),  and the reporting
requirements of the Securities Act and the Exchange Act, (ii) a copy of the most
recent annual or quarterly  report of the Company,  and (iii) such other reports
and  documents  of the  Company as such holder may  reasonably  request to avail
itself of any similar rule or regulation of the  Commission  allowing it to sell
any such securities without registration.

     11. MERGERS, ETC. The Company shall not, directly or indirectly, enter into
any merger,  consolidation or  reorganization  in which the Company shall not be
the surviving corporation unless the proposed surviving corporation shall, prior
to such merger, consolidation or reorganization,  agree in writing to assume the
obligations of the Company under this Agreement, and for that purpose references
hereunder  to  "Registrable  Shares"  shall be  deemed to be  references  to the
securities which the  Stockholders  would be entitled to receive in exchange for
Registrable  Shares  under any such  merger,  consolidation  or  reorganization;
PROVIDED, HOWEVER, that the provisions of this Section 11 shall not apply in the
event of any merger, consolidation or reorganization in which the Company is not
the  surviving  corporation  if all  Stockholders  are  entitled  to  receive in
exchange for their  Registrable  Shares  consideration  consisting solely of (i)
cash, (ii) securities of the acquiring corporation which may be immediately sold
to the public without registration under the Securities Act, or (iii) securities
of the  acquiring  corporation  which the  acquiring  corporation  has agreed to
register  within 90 days of  completion  of the  transaction  for  resale to the
public pursuant to the Securities Act.

     12. TERMINATION.  All of the Company's  obligations to register Registrable
Shares  under  this  Agreement  shall  terminate  on the later of (i) the second
anniversary of this Agreement and (ii) in the case of Registrable  Shares issued
or issuable upon exchange of the Note, the first  anniversary of the issuance of
such  shares,  or in the case of  Registrable  Shares  issued or  issuable  upon
exchange  of the  Preferred  Shares,  the first  anniversary  of such  issuance.
Notwithstanding  anything  to the  contrary  in this  Section  12,  no holder of
Registrable  Shares  shall be entitled to cause the Company to register the sale
of  Registrable  Shares  if and so  long  as  the  intended  sale  may  then  be
effectuated by such holder in compliance with Rule 144 under the Securities Act.

     13. TRANSFERS OF RIGHTS. This Agreement,  and the rights and obligations of
each Selling Stockholder hereunder,  may be assigned by such Selling Stockholder
to any  person or entity to which  Registrable  Shares are  transferred  by such
Selling Stockholder, and such transferee shall be deemed a "Selling Stockholder"
for purposes of this Agreement;  provided that the transferee  provides  written
notice of such assignment to the Company.

FOR IMMEDIATE RELEASE                CONTACT: Robert W. Lougee, Jr.
Monday,  June 8,1998                          Vice President, Investor Relations

              ARCH ANNOUNCES PLAN TO STRENGTHEN CAPITAL STRUCTURE,
                INCREASE FINANCIAL FLEXIBILITY FOR FUTURE GROWTH


       INITIATIVE INCLUDES NEW CREDIT FACILITY, PRIVATE EQUITY PLACEMENT,
                              SENIOR NOTE OFFERING


Westborough,   MA  (June  8,   1998)  ---  Arch   Communications   Group,   Inc.
(NASDAQ:APGR),  the nation's second largest paging company, today announced that
it has  initiated  plans  to  significantly  strengthen  its  capital  structure
through: (1) a new $400 million bank credit facility;  (2) the private placement
of $23 million to $25 million of convertible preferred stock; (3) a $125 million
issuance  of senior  notes to  qualified  institutional  buyers  (in a Rule 144A
offering); and (4) the merger of certain operating subsidiaries.  The initiative
is intended to simplify  Arch's  capital and legal  structure as well as provide
increased financial flexibility for future growth.

"We are extremely pleased to announce this capital  restructuring plan," said C.
Edward Baker,  Jr., chairman and chief executive  officer.  "Completion of these
initiatives will  substantially  increase our financial  flexibility and give us
the  opportunity to effectively  execute our growth  strategies.  We believe the
commitment  of new  capital  resources  clearly  represents  a  strong  vote  of
confidence in Arch and our business  plan,  as well as growth  prospects for the
paging sector as a whole."


<PAGE>

J. Roy Pottle, Arch executive vice president and chief financial officer, added:
"Obviously,  we are very pleased with the continued  support of our banks.  Most
importantly,  the new credit  facility  eliminates  $156  million  of  principal
payments that otherwise would have been required over the next three years.  The
new  credit  facility  requires  no  principal   payments  until  2001,  and  is
considerably more flexible than the existing 3 1/2-year-old facility."

The strengthening of Arch's capital structure is a multi-step  process that will
begin with consolidation of the Company's legal structure.  Arch  Communications
Enterprises, Inc. (ACE), a wholly owned subsidiary of Arch Communications Group,
Inc.  (ACG),   will  merge  with  the  operating   subsidiaries  of  USA  Mobile
Communications,  Inc. II (USAM) and the  surviving  legal entity will be renamed
Arch Paging,  Inc. (API).  Another wholly owned subsidiary of ACG, USAM, will be
renamed  Arch  Communications,  Inc.  (ACI) and will own all of the  outstanding
capital stock of API. The current  operating  subsidiaries of ACE will be wholly
owned by API and will continue to exist in their present form.

Arch has received  commitments from a group of lenders to provide a $400 million
credit  facility to API.  The new  facility  will be comprised of a $175 million
reducing revolver, a $100 million 364-day facility which automatically  converts
on the 364th day to a six-year term loan,  and an  eight-year  $125 million term
loan. The reducing  revolver and the  364-day/term  loan will mature on June 30,
2005,  and the $125  million  term loan will  mature on June 30,  2006.  The new
credit facility,  which includes one new lender and 12 of the Company's existing
lenders,  will be led by The Bank of New York,  Toronto Dominion (Texas),  Inc.,
and Royal Bank of Canada. The new credit facility will be established through an
amendment and restatement of ACE's existing credit facility.

In addition,  Arch has received a commitment from Sandler Capital  Management to
purchase $23 million to $25 million of  preferred  stock  convertible  into Arch
common  stock at an initial  conversion  price of $5.50 per share.  A cumulative
dividend  of 8.00%  will  accrue  on the  preferred  stock,  payable  at  Arch's
discretion  in cash or shares of Arch common  stock.  The  preferred  stock will
include certain other  redemption,  voting and preemptive rights and restrictive
provisions. Also, Sandler Managing


<PAGE>

Director John Kornreich  will be named to Arch's Board of Directors.  Commenting
on the commitment,  Kornreich said: "With a greatly improved  financial footing,
we think Arch can sustain solid cash flow growth,  deleverage its balance sheet,
and participate in the ongoing consolidation of the paging industry."

Founded in 1980, Sandler is a New York-based private investment  management firm
with  more  than  $1.4  billion  in equity  assets  under  management.  The firm
specializes in investments in the  telecommunications and media sectors. "We are
delighted to receive  financial  support from such a highly regarded  investment
firm," said Baker,  "especially  one that strongly  favors  consolidation  among
paging companies.  John Kornreich is among the most  knowledgeable  investors in
this business and we welcome him as a member of the Arch Board."

Finally, ACI will commence a Rule 144A offering of $125 million of senior notes.
Proceeds from the issuance of the senior  notes,  along with those from the sale
of convertible  preferred  stock and borrowings  under the new credit  facility,
will be used to repay  bank  debt  outstanding  under the  current  ACE and USAM
credit facilities. Upon closing of these transactions,  the existing USAM credit
facility will be terminated.

The new credit facility,  preferred stock placement and senior note issuance are
mutually contingent and subject to certain other customary  conditions,  and are
expected to be completed  simultaneously.  The actual timing of these  financing
activities  will depend on market  conditions and other  factors.  The preferred
stock and senior notes have not been registered under the Securities Act of 1933
and may not be offered or sold in the United  States absent  registration  or an
applicable exemption from registration requirements.  This announcement does not
constitute an offer to sell any securities.

Arch Communications Group, Inc.,  Westborough,  MA, is the second largest paging
company in the United  States as ranked by  annualized  operating  cash flow. It
provides  narrowband  wireless messaging  services,  principally paging, to more
than four million subscribers  nationwide through  approximately 200 offices and

                 PRIVATE EQUITY PLACEMENT, SENIOR NOTE OFFERING


Westborough,   MA  (June  30,  1998)  ---  Arch   Communications   Group,   Inc.
(NASDAQ:APGR),  the nation's  second largest paging  company,  today said it has

provides us with substantially increased financial flexibility, but gives us the
opportunity  to pursue  long-term  operating  strategies  and  focus on  growing
shareholder  value."  Baker  added:  "We are  especially  pleased that these new
commitments   reflect  a  strong  vote  of  confidence  both  in  Arch's  growth
opportunities as well as those of the paging industry as a whole."

The new $400 million credit  facility,  which is available to an indirect wholly
owned  subsidiary,  Arch  Paging,  Inc.  (API),  is  comprised of a $175 million
reducing revolver, a $100 million 364-day facility which automatically  converts
on the 364th day into a six-year term loan, and an eight-year  $125 million term
loan. The reducing  revolver and the  364-day/term  loan will mature on June 30,
2005,

and the $125  million  term loan will  mature on June 30,  2006.  The new credit
facility was led by The Bank of New York,  Toronto Dominion  (Texas),  Inc., and
Royal Bank of Canada. The new facility was established  through an amendment and
restatement of the prior bank facility of Arch Communications Enterprises,  Inc.
(ACE), a wholly owned subsidiary of Arch.

Arch  also  completed  the  private  placement  of $25  million  of  convertible
preferred  stock to  partnerships  managed by  Sandler  Capital  Management  and
certain  other  investors at an initial  conversion  price of $5.50 per share of
Arch common  stock.  A  cumulative  dividend of 8.00%  accrues on the  preferred
stock,  payable at Arch's discretion in cash or shares of Arch common stock. The
preferred stock includes certain other redemption,  voting and preemptive rights
and restrictive  provisions.  Also, Sandler Managing Director John Kornreich has
been named to the Boards of Directors of Arch and ACI.

In addition, ACI has completed its Senior Note offering. Made only to "qualified
institutional buyers" under Rule 144A, ACI sold $130 million principal amount of
12 3/4% Senior Notes due 2007 at an initial price to investors of 98.049%.

Concurrently  with  the  above  transactions,   Arch  completed  the  previously
announced  consolidation  of its  legal  structure.  ACE  was  merged  with  the
operating  subsidiaries  of USAM and the surviving legal entity was renamed API.
USAM was renamed ACI and now owns all of the  outstanding  capital stock of API.
The former operating subsidiaries of ACE are now wholly owned by API.

J. Roy Pottle, Arch executive vice president and chief financial officer, noted:
"There are many benefits from this  restructuring,  including the elimination of
$156 million of near-term amortization. Most importantly, however, we now have a
capital structure that is easier to understand and positions Arch to participate
in ongoing industry consolidation."
