6.    REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

      In order to induce Coast to enter into this  Agreement  and to make Loans,
Borrower  represents  and warrants to Coast as follows,  and Borrower  covenants
that the following  representations  will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

      6.1  Existence  and  Authority.  Borrower is and will continue to be, duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its organization.  Borrower is and will continue to be qualified
and licensed to do business in all  jurisdictions  in which any failure to do so
would have a Material Adverse Effect. The execution, delivery and performance by
Borrower of this Agreement, and all other documents contemplated hereby (a) have
been duly and  validly  authorized,  (b) are  enforceable  against  Borrower  in
accordance  with their terms (except as enforcement  may be limited by equitable
principles and by bankruptcy, insolvency, reorganization,  moratorium or similar
laws relating to creditors' rights generally), and (c) do not violate Borrower's
articles or certificate of incorporation,  or Borrower's  by-laws, or any law or
any material  agreement  or  instrument  which is binding  upon  Borrower or its
property,  and (d) do not constitute  grounds for  acceleration  of any material
indebtedness or obligation  under any material  agreement or instrument which is
binding upon Borrower or its property.

      6.2 Name;  Trade Names and Styles.  The name of Borrower  set forth in the
heading to this  Agreement is its correct  name.  Listed on the Schedule are all
prior names of Borrower  and all of  Borrower's  present and prior trade  names.
Borrower shall give Coast thirty (30) days' prior written notice before changing
its name or doing business under any other name. Borrower has complied, and will
in the future comply,  with all laws relating to the conduct of business under a
fictitious business name.

      6.3 Place of Business;  Location of  Collateral.  The address set forth in
the heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business and  Collateral is located only at the locations
set forth on the  Schedule.  Borrower will give Coast at least thirty (30) days'
prior written notice before opening any additional  place of business,  changing
its chief executive  office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.

      6.4 Title to Collateral; Permitted Liens. Borrower is now, and will at all
times in the future be, the sole owner of all the  Collateral,  except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain

free and clear of any and all liens, charges,  security interests,  encumbrances
and adverse claims, except for Permitted Liens. Coast now has, and will continue
to have, a first-priority  perfected and enforceable security interest in all of
the Collateral,  subject only to the Permitted  Liens,  and Borrower will at all
times defend Coast and the Collateral against all claims of others.  None of the
Collateral  now is or will be affixed to any real property in such a manner,  or
with such intent, as to become a fixture.  Borrower is not and will not become a
lessee under any real property lease pursuant to which the lessor may obtain any
rights in any of the  Collateral  and no such  lease now  prohibits,  restrains,
impairs or will  prohibit,  restrain  or impair  Borrower's  right to remove any
Collateral  from the leased  premises.  Whenever any  Collateral is located upon
premises in which any third party has an interest (whether as owner,  mortgagee,
beneficiary under a deed of trust, lien or otherwise),  Borrower shall, whenever
requested  by Coast,  use its best  efforts to cause such third party to execute
and  deliver  to  Coast,  in  form   acceptable  to  Coast,   such  waivers  and
subordinations  as Coast shall  specify,  so as to ensure that Coast's rights in
the Collateral  are, and will continue to be, superior to the rights of any such
third party.  Borrower will keep in full force and effect,  and will comply with
all the terms of, any lease of real property  where any of the Collateral now or
in the future may be located.

      6.5  Maintenance of  Collateral.  Borrower will maintain the Collateral in
good  working  condition,  and  Borrower  will  not use the  Collateral  for any
unlawful  purpose.  Borrower  will  immediately  advise  Coast in writing of any
material loss or damage to the Collateral.

      6.6 Books and  Records.  Borrower  has  maintained  and will  maintain  at
Borrower's  Address  complete and  accurate  books and  records,  comprising  an
accounting system in accordance with GAAP.

      6.7 Financial Condition,  Statements and Reports. All financial statements
now or in the future  delivered  to Coast have been,  and will be,  prepared  in
conformity with GAAP (except, in the case of unaudited financial statements, for
the absence of footnotes and subject to normal year-end adjustments) and now and
in the future will fairly  reflect the financial  condition of Borrower,  at the
times and for the periods therein  stated.  Between the last date covered by any
such statement provided to Coast and the date hereof, there has been no Material
Adverse Effect. Borrower is now and will continue to be Solvent.

      6.8 Tax Returns and Payments;  Pension Contributions.  Borrower has timely
filed,  and will timely file,  all tax returns and reports  required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all  foreign,  federal,  state  and  local  taxes,  assessments,   deposits  and
contributions  now or in the future owed by  Borrower.  Borrower  may,  however,
defer payment of any contested  taxes,  provided that Borrower (i) in good faith
contests  Borrower's  obligation  to pay the  taxes by  appropriate  proceedings
promptly and diligently instituted and conducted, (ii) notifies Coast in writing
of the  commencement of, and any material  development in, the proceedings,  and
(iii) posts bonds or takes any other steps required to keep the contested  taxes
from becoming a lien upon any of the Collateral. As of the date hereof, Borrower
is unaware of any claims or adjustments proposed for any of Borrower's prior tax
years  which  could  result in  additional  taxes  becoming  due and  payable by
Borrower.  Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future  pension,  profit sharing and deferred  compensation

plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete  termination of, or permit the
occurrence  of any other event with respect to, any such plan which could result
in any liability of Borrower,  including  any  liability to the Pension  Benefit
Guaranty Corporation or its successors or any other governmental agency. Without
limiting any of Coast's other rights and remedies under this Agreement, upon the
occurrence  of an Event of Default,  Borrower  shall  utilize the services of an
outside payroll service providing for the automatic deposit of all payroll taxes
payable by Borrower.

      6.9 Compliance with Law.  Borrower has complied,  and will comply,  in all
material respects,  with all provisions of all material foreign,  federal, state
and local laws and regulations relating to Borrower,  including, but not limited
to, the Fair Labor Standards Act, and those relating to Borrower's  ownership of
real or personal property, the conduct and licensing of Borrower's business, and
environmental matters.

      6.10 Litigation.  Except as disclosed in the Schedule,  there is no claim,
suit, litigation,  proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any  governmental  agency (or any basis  therefor  known to Borrower)  which may
result,  either  separately or in the aggregate,  in a Material  Adverse Effect.
Borrower  will  promptly  inform  Coast in  writing  of any  claim,  proceeding,
litigation or investigation in the future threatened or instituted by or against
Borrower involving an amount set forth on the Schedule.

      6.11 Use of  Proceeds.  All proceeds of all Loans shall be used solely for
lawful  business  purposes.  Borrower is not  purchasing or carrying any "margin
stock" (as  defined in  Regulation  G of the Board of  Governors  of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any  "margin  stock" or to extend  credit to others for the  purpose of
purchasing or carrying any "margin stock."

      6.12 Year 2000  Compliance.  Borrower  represents  and warrants  that with
respect to the computer  systems,  software and applications of Borrower and its
material suppliers, vendors and customers, the Year 2000 Problem will not result
in a Material Adverse Effect.

7.    RECEIVABLES.

      7.1  Representations  Relating to  Receivables.  Borrower  represents  and
warrants to Coast as follows:  Each  Receivable  with respect to which Loans are
requested  by  Borrower  shall,  on the date  each Loan is  requested  and made,
represent an  undisputed  bona fide  existing  unconditional  obligation  of the
Account  Debtor  created by the sale,  delivery and  acceptance  of goods or the
rendition of services in the ordinary course of Borrower's business.

      7.2 Representations  Relating to Documents and Legal Compliance.  Borrower
represents and warrants to Coast as follows:  All statements made and all unpaid
balances appearing in all invoices,  instruments and other documents  evidencing
the  Receivables  are and  shall be true  and  correct  and all  such  invoices,
instruments and other documents and all of Borrower's  books and records are and
shall be  genuine  and in all  respects  what they  purport to be. All sales and
other  transactions  underlying  or giving rise to each  Receivable  shall fully
comply with all applicable  laws and  governmental  rules and  regulations.  All
signatures  and  endorsements  on all  documents,  instruments,  and  agreements
relating to all  Receivables  are and shall be genuine,  and all such documents,
instruments  and agreements  are and shall be legally  enforceable in accordance
with their terms.

      7.3  Schedules  and  Documents  relating to  Receivables.  Borrower  shall
deliver to Coast via  facsimile,  unless  otherwise  directed by Coast,  at such
locations and at such  intervals as Coast may request,  transaction  reports and
loan requests,  schedules of Receivables,  and schedules of collections,  all on
Coast's standard forms;  provided,  however,  that Borrower's failure to execute
and deliver the same shall not affect or limit  Coast's  security  interest  and
other rights in all of  Borrower's  Receivables,  nor shall  Coast's  failure to
advance or lend against a specific  Receivable  affect or limit Coast's security
interest and other rights therein.  Loan requests  received after 10:30 A.M. Los
Angeles,  California  time,  will  not be  considered  by Coast  until  the next
Business Day. Together with each such schedule,  or later if requested by Coast,
Borrower shall furnish Coast with copies (or, at Coast's request,  originals) of
all contracts,  orders,  invoices, and other similar documents, and all original
shipping instructions, delivery receipts, bills of lading, and other evidence of
delivery,  for any  goods  the sale or  disposition  of which  gave rise to such
Receivables,  and Borrower  warrants the  genuineness  of all of the  foregoing.
Borrower shall also furnish to Coast an aged accounts  receivable  trial balance
in such form and at such intervals as Coast shall request. In addition, Borrower
shall deliver to Coast the originals of all instruments, chattel paper, security
agreements,  guarantees and other documents and property  evidencing or securing
any Receivables, upon receipt thereof and in the same form as received, with all
necessary endorsements, all of which shall be with recourse. Borrower shall also
provide Coast with copies of all credit memos as and when requested by Coast.

      7.4  Collection of  Receivables.  Borrower shall have the right to collect
all  Receivables,  unless and until an Event of Default has  occurred.  Borrower
shall hold all payments on, and proceeds of, Receivables in trust for Coast, and
Borrower  shall  deliver all such  payments and proceeds to Coast within one (1)
Business Day after receipt by Borrower, in their original form, duly endorsed to
Coast, to be applied to the Obligations in such order as Coast shall  determine.
Notwithstanding  the  foregoing,  if an  exceptional  circumstance  arises which
precludes  Borrower  from  delivering  to Coast a particular  item of payment or
proceed of a Receivable  within one (1) Business Day after  receipt by Borrower,
Borrower shall deliver such payment and proceed to Coast as soon as practicable,
but in no event later than three (3)  Business  Days after  receipt by Borrower.
Coast may,  in its  discretion,  require  that all  proceeds  of  Collateral  be
deposited by Borrower into a lockbox account, or such other "blocked account" as
Coast may specify, pursuant to a blocked account agreement in such form as Coast
may specify. Coast or its designee may, at any time, notify Account Debtors that
Coast has been granted a security interest in the Receivables.

      7.5 Remittance of Proceeds.  All proceeds  arising from the disposition of
any  Collateral  shall be  delivered  to Coast within one (1) Business Day after
receipt by Borrower,  in their  original  form,  duly  endorsed to Coast,  to be
applied  to  the   Obligations   in  such  order  as  Coast   shall   determine.
Notwithstanding  the  foregoing,  if an  exceptional  circumstance  arises which
precludes   Borrower  from  delivering  to  Coast  proceeds  obtained  from  the
disposition of any item of Collateral  within one (1) Business Day after receipt
by  Borrower,  Borrower  shall  deliver  such  proceeds  to  Coast  as  soon  as
practicable, but in no event later than three (3) Business Days after receipt by
Borrower. Borrower agrees that it will not commingle proceeds of Collateral with
any of Borrower's other funds or property,  but will hold such proceeds separate
and apart from such other funds and property and in an express  trust for Coast.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.

      7.6  Disputes.  Borrower  shall  notify  Coast  promptly  of all  material
disputes or claims relating to material Receivables.  Borrower shall not forgive
(completely  or  partially),  compromise or settle any  Receivable for less than
payment in full, or agree to do any of the  foregoing,  except that Borrower may
do so,  provided  that:  (a) Borrower does so in good faith,  in a  commercially
reasonable  manner,  in the  ordinary  course of  business,  and in arm's length
transactions,  which are  reported to Coast on the regular  reports  provided to
Coast;  (b) no Default or Event of Default has occurred and is  continuing;  and
(c) taking into account all such  discounts  settlements  and  forgiveness,  the
total outstanding Loans will not exceed the Credit Limit. Coast may, at any time
after an Event of  Default  has  occurred  and is  continuing,  settle or adjust
disputes  or claims  directly  with  Account  Debtors for amounts and upon terms
which Coast  considers  advisable in its reasonable  credit judgment and, in all
cases,  Coast shall  credit  Borrower's  Loan  account with only the net amounts
received by Coast in payment of any Receivables.

      7.7 Returns.  Provided no Event of Default has occurred and is continuing,
if any Account Debtor  returns any Inventory to Borrower in the ordinary  course
of its business,  Borrower shall  promptly  determine the reason for such return
and promptly issue a credit  memorandum to the Account Debtor in the appropriate
amount.  In the event any attempted  return  occurs after the  occurrence of any
Event of Default,  Borrower  shall (a) hold the returned  Inventory in trust for
Coast,  (b)  segregate  all  returned  Inventory  from all of  Borrower's  other
property,  (c) conspicuously  label the returned Inventory as subject to Coast's
security  interest,  and (d)  immediately  notify  Coast  of the  return  of any
Inventory,  specifying the reason for such return, the location and condition of
the returned  Inventory,  and on Coast's request deliver such returned Inventory
to Coast.

      7.8  Verification.  Coast may, from time to time, verify directly with the
respective  Account Debtors the validity,  amount and other matters  relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Coast or such other name as Coast may choose.

      7.9 No Liability.  Coast shall not under any  circumstances be responsible
or liable for any shortage or discrepancy  in, damage to, or loss or destruction
of,  any  goods,  the  sale  or  other  disposition  of  which  gives  rise to a
Receivable,  or for any error,  act,  omission or delay of any kind occurring in
the  settlement,  failure to  settle,  collection  or  failure  to  collect  any
Receivable,  or for settling any Receivable in good faith for less than the full
amount  thereof,  nor  shall  Coast  be  deemed  to be  responsible  for  any of
Borrower's  obligations  under  any  contract  or  agreement  giving  rise  to a
Receivable.  Nothing herein shall, however, relieve Coast from liability for its
own gross negligence or willful misconduct.

8.    ADDITIONAL DUTIES OF THE BORROWER.

      8.1  Financial  and Other.  Borrower  shall at all times  comply  with the
financial and other covenants set forth in the Schedule.

      8.2  Insurance.  Borrower  shall,  at all times insure all of the tangible
personal  property  Collateral  and carry such other  business  insurance,  with
insurers  reasonably  acceptable to Coast, in such form and amounts as Coast may
reasonably  require,  and Borrower  shall provide  evidence of such insurance to

Coast,  so that Coast is satisfied that such insurance is, at all times, in full
force and effect. All liability  insurance policies of Borrower shall name Coast
as an  additional  insured,  and all  property  casualty  and related  insurance
policies of Borrower shall name Coast as a loss payee thereon and Borrower shall
cause a lender's loss payee endorsement in form reasonably  acceptable to Coast.
Upon  receipt of the  proceeds  of any such  insurance,  Coast  shall apply such
proceeds in reduction of the  Obligations  as Coast shall  determine in its sole
discretion,  except  that,  provided no Default or Event of Default has occurred
and is  continuing,  Coast shall  release to Borrower  insurance  proceeds  with
respect to Equipment totaling less than the amount set forth in Section 8 of the
Schedule,  which  shall be  utilized  by  Borrower  for the  replacement  of the
Equipment  with respect to which the  insurance  proceeds  were paid.  Coast may
require reasonable  assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any  insurance,  Coast may, but is
not obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Coast copies of all reports made to insurance companies.

      8.3  Reports.  Borrower,  at its  expense,  shall  provide  Coast with the
written  reports set forth in Section 8 of the Schedule,  and such other written
reports  with  respect  to  Borrower  (including  budgets,   sales  projections,
operating plans and other financial documentation),  as Coast shall from time to
time reasonably specify.

      8.4 Access to Collateral, Books and Records. At reasonable times but under
ordinary  circumstances  not  more  frequently  than  quarterly  and on one  (1)
Business  Day's notice,  Coast,  or its agents,  shall have the right to perform
Audits.  Coast may  conduct  more  frequent  Audits if Coast,  in its good faith
discretion,  deems the same to be  necessary  or  appropriate.  Coast shall take
reasonable steps to keep confidential all confidential  information  obtained in
any Audit,  but Coast shall have the right to disclose any such  information  to
its auditors,  regulatory agencies, and attorneys,  and pursuant to any subpoena
or other legal process. The Audits shall be at Borrower's expense and the charge
for the Audits shall be Seven Hundred  Fifty  Dollars  ($750) per person per day
(or such higher amount as shall represent  Coast's then current  standard charge
for the same), plus reasonable  out-of-pocket expenses.  Borrower will not enter
into any agreement  with any accounting  firm,  service bureau or third party to
store Borrower's books or records at any location other than Borrower's Address,
without first  notifying  Coast of the same and obtaining the written  agreement
from such accounting firm, service bureau or other third party to give Coast the
same  rights with  respect to access to books and records and related  rights as
Coast has under this Loan  Agreement.  Borrower  shall  also take all  necessary
steps  to  assure  that  its  material  accounting  and  software,  systems  and
applications,  and those of its  accounting  firm,  service  bureau or any other
third  party  vendor  or  supplier,  will,  on a timely  basis,  adequately  and
completely address the Year 2000 Problem in all material aspects.

      8.5 Negative Covenants.  Borrower shall not, without Coast's prior written
consent, do any of the following:

            (a)  merge  or  consolidate   with  another  entity,   except  in  a
transaction  in which (i) the owners of the Borrower hold at least fifty percent
(50%) of the ownership  interest in the surviving entity  immediately after such
merger or consolidation, and (ii) the Borrower is the surviving entity;

            (b)  acquire  any  assets,  except  (i) in the  ordinary  course  of
business, or (ii) in a transaction or a series of transactions not involving the
payment of an aggregate amount in excess of the amount set forth in Section 8 of
the Schedule;

            (c) enter into any other transaction  outside the ordinary course of
business;

            (d) sell or transfer any Collateral, except for the sale of finished
Inventory in the ordinary course of Borrower's business, and except for the sale
of obsolete or unneeded Equipment in the ordinary course of business;

            (e) store any Inventory or other Collateral with any warehouseman or
other third party;

            (f)  sell  any  Inventory  on  a  sale-or-return,  guaranteed  sale,
consignment, or other contingent basis;

            (g) make any loans of any money or other assets, except (i) advances
to  customers or  suppliers  in the  ordinary  course of  business,  (ii) travel
advances, employee relocation loans and other employee loans and advances in the
ordinary  course  of  business,  and  (iii)  loans to  employees,  officers  and
directors for the purpose of purchasing equity securities of the Borrower;

            (h) incur any debts,  except to VIALOG,  outside the ordinary course
of business, which would have a Material Adverse Effect;

            (i)  guarantee  or  otherwise  become  liable  with  respect  to the
obligations of another party or entity;

            (j) pay or declare any dividends or  distributions  on the ownership
interests in Borrower except for (i) dividends or  distributions  payable solely
in stock form of ownership  interests  in Borrower and (ii)  dividends to VIALOG
if,   when  and  to  the   extent   required   by   VIALOG   in  order  to  make
regularly-scheduled payments of principal and interest on the $75,000,000.00, 12
3/4% Senior Notes issued by VIALOG,  provided such  dividends or payments on the
12 3/4%  Senior  Notes  would not  result in a Default  or Event of  Default  by
Borrower or VIALOG with respect to any of their respective obligations to Coast.
Borrower  may make loans,  advances  and  transfers  to VIALOG  provided (i) the
Borrower is and will continue to be able to generally pay its obligations as and
when due;  and (ii) VIALOG owns all of the  outstanding  ownership  interests in
Borrower as of the time of the loan,  advance or transfer.  Neither Borrower nor
VIALOG shall,  without the prior written consent of Coast,  which consent may be
granted  or  withheld  by Coast in its sole  and  absolute  discretion,  redeem,
purchase or retire all or any portion of the Senior  Notes prior to November 15,
2001,  unless  such  redemption,  purchase  or  retirement  is (i) funded by the
proceeds of an equity offering or (ii) the proceeds of a debt offering where the
debt  offering  is  subordinated  in all  respects to Coast  including,  but not
limited to Coast`s claims, Coast's rights to payment, and Coast's Collateral.

            (k) make any change in Borrower's capital structure which would have
a Material Adverse Effect; or

            (l) dissolve or elect to dissolve.

      Transactions  permitted by the  foregoing  provisions  of this Section are
only permitted if no Default or Event of Default is continuing or would occur as
a result of such transaction.

      8.6 Litigation  Cooperation.  Should any third-party suit or proceeding be
instituted  by or against  Coast with respect to any  Collateral  or relating to
Borrower,  Borrower shall, without expense to Coast, make available Borrower and
its officers,  employees  and agents and  Borrower's  books and records,  to the
extent that Coast may deem them  reasonably  necessary  in order to prosecute or
defend any such suit or proceeding.

      8.7 Further  Assurances.  Borrower agrees,  at its expense,  on request by
Coast,  to  execute  all  documents  and take all  actions,  as Coast,  may deem
reasonably  necessary  or  useful  in  order to  perfect  and  maintain  Coast's
perfected security interest in the Collateral,  and in order to fully consummate
the transactions contemplated by this Agreement.

9.    TERM.

      9.1  Maturity  Date.  This  Agreement  shall  continue in effect until the
Maturity Date;  provided that the Maturity Date shall automatically be extended,
and this Agreement shall  automatically  and continuously  renew, for successive
additional terms of one year each,  unless one party gives written notice to the
other,  not less than  ninety (90) days prior to the  Maturity  Date or the next
Renewal Date,  that such party elects to terminate this  Agreement  effective on

after written notice of  termination  is given to Coast;  or (b) by Coast at any

payable on the effective date of termination and thereafter  shall bear interest
at a rate equal to the rate applicable to the Receivable Loans.

      9.3  Payment  of  Obligations.  On the  Maturity  Date  or on any  earlier
effective  date of  termination,  Borrower  shall  pay and  perform  in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such  Obligations  are  otherwise  then due and  payable.
Notwithstanding  any  termination  of this  Agreement,  all of Coast's  security
interests in all of the  Collateral  and all of the terms and provisions of this
Agreement  shall  continue in full force and effect until all  Obligations  have
been paid and performed in full;  provided that,  without limiting the fact that
Loans are subject to the discretion of Coast, Coast may, in its sole discretion,
refuse to make any further Loans after termination.  No termination shall in any
way  affect  or  impair  any  right or  remedy  of  Coast,  nor  shall  any such
termination  relieve  Borrower  of any  Obligation  to  Coast,  until all of the
Obligations  have been paid and performed in full.  Upon payment and performance
in full of all the Obligations  and  termination of this Agreement,  Coast shall
promptly deliver to Borrower termination statements,  requests for reconveyances
and such other documents as may be required to fully terminate  Coast's security
interests.

      9.4 Revivor.  Notwithstanding Section 9.3 or any other provision contained
in any of the Loan  Documents  to the  contrary,  if any claim is ever made upon
Coast by any  claimant  (except  for lender  liability  or like claims by VIALOG
and/or  the  Borrower),  for  repayment  or  recovery  of any  amount or amounts
received  by Coast in payment of or on  account  of any of the  Indebtedness  or
because of any claim that any such payment  constituted a preferential  transfer
or fraudulent  conveyance,  or for any other claim of any kind, and Coast repays
all or part of said  amount by reason  of any  judgment,  decree or order of any
court  or  administrative  body  having  jurisdiction  over  Coast or any of its
property,  or by  reason  of any  settlement  or  compromise  of any such  claim
effected by Coast with any such claimant,  then and in any such event,  Borrower
agrees that any such judgment,  decree, order, settlement or compromise shall be
binding  upon  Borrower,  notwithstanding  any prior  release of Borrower or any
Guarantor or the cancellation of any note or other instrument  evidencing any of
the Indebtedness, or any release of any of the Indebtedness,  and Borrower shall
be and remain  liable to Coast  hereunder for the amount so repaid or recovered,
to the same extent as if such amount had never originally been received by Coast
(the Revived Obligations").  The Revived Obligations of Borrower hereunder shall
be immediately due and payable,  shall bear interest at the rate herein provided
and secured by the Collateral. 

10.   EVENTS OF DEFAULT AND REMEDIES.

      10.1 Events of Default.  The  occurrence  of any of the  following  events
shall constitute an "Event of Default" under this Agreement,  and Borrower shall

            (e) Borrower  shall fail to comply with the financial  covenants (if

Obligation,  which  failure is not cured within ten (10) Business Days after the

dissolution or  liquidation  law or statute of any  jurisdiction,  now or in the
future in effect; or

            (k) the  commencement  of any  proceeding  against  Borrower  or any
guarantor  of any of  the  Obligations  under  any  reorganization,  bankruptcy,

statute of any  jurisdiction,  now or in the future in effect,  which is (i) not
timely  controverted,  or  (ii)  not  cured  by  the  dismissal  thereof  within
forty-five  (45) days after the date commenced;  or within any applicable  grace
period; or

            (l)  revocation  or  termination  of,  or  limitation  or  denial of

obligations terminates or in any way limits his subordination agreement; or

            (o) Except as permitted under Section 8.5(a),  Borrower shall suffer
or experience any Change of Control without Coast's prior written consent, which

business judgment; or

            (p) Borrower  shall  generally not pay its debts as they become due,
or Borrower  shall  conceal,  remove or transfer any part of its property,  with
intent to hinder, delay or defraud its creditors, or make or suffer any transfer
of any of its property which may be fraudulent under any bankruptcy,  fraudulent
conveyance or similar law; or

            (q) there  shall be any  Material  Adverse  Effect.  Coast may cease
making any Loans or extending any credit  hereunder during any of the above cure
periods.

      10.2 Remedies.  Upon the occurrence,  and during the  continuance,  of any
Event of Default, Coast, at its option, and without notice or demand of any kind
(all of which are hereby expressly  waived by Borrower),  may do any one or more
of the following:

            (a) Cease  making Loans or  otherwise  extending  credit to Borrower
under this Agreement or any other document or agreement;

            (b) Accelerate and declare all or any part of the  Obligations to be
immediately  due,  payable  and  performable,  notwithstanding  any  deferred or
installment  payments  allowed by any  instrument  evidencing or relating to any
Obligation;

            (c) Take possession of any or all of the Collateral  wherever it may
be found, and for that purpose Borrower hereby authorizes Coast without judicial
process to enter onto any of Borrower's premises without  interference to search
for, take possession of, keep, store or remove any of the Collateral, and remain
on the  premises or cause a  custodian  to remain on the  premises in  exclusive
control  thereof,  without  charge  for so long as  Coast  deems  it  reasonably
necessary  in order  to  complete  the  enforcement  of its  rights  under  this
Agreement or any other agreement;  provided,  however, that should Coast seek to
take  possession of any of the  Collateral  by Court  process,  Borrower  hereby
irrevocably waives:

                  (i) any bond  and any  surety  or  security  relating  thereto
      required by any  statute,  court rule or  otherwise as an incident to such
      possession;

                  (ii) any demand for possession  prior to the  commencement  of
      any suit or action to recover possession thereof; and

                  (iii) any requirement that Coast retain possession of, and not
      dispose of, any such Collateral until after trial or final judgment;

            (d) Require  Borrower to assemble any or all of the  Collateral  and
make it available to Coast at places  designated  by Coast which are  reasonably
convenient to Coast and Borrower, and to remove the Collateral to such locations
as Coast may deem advisable;

            (e)  Complete  the  processing,   manufacturing  or  repair  of  any
Collateral  prior to a  disposition  thereof  and,  for such purpose and for the
purpose  of  removal,  Coast  shall have the right to use  Borrower's  premises,
vehicles,  hoists,  lifts,  cranes,  equipment  and all other  property  without
charge. Coast is hereby granted a license or other right to use, without charge,
Borrower's  labels,  patents,  copyrights,  rights  of use of  any  name,  trade
secrets, trade names, trademarks,  service marks, and advertising matter, or any
property of a similar nature,  as it pertains to the  Collateral,  in completing
production of,  advertising  for sale, and selling any Collateral and Borrower's
rights under all licenses and all  franchise  agreements  shall inure to Coast's
benefit;

            (f) Sell,  lease or otherwise  dispose of any of the Collateral,  in
its  condition  at the time  Coast  obtains  possession  of it or after  further
manufacturing, processing or repair, at one or more public and/or private sales,
in lots or in bulk, for cash,  exchange or other property,  or on credit, and to
adjourn  any  such  sale  from  time to time  without  notice  other  than  oral
announcement  at the time  scheduled  for sale.  Coast  shall  have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Coast deems reasonable,  or on Coast's  premises,  or elsewhere and the
Collateral need not be located at the place of  disposition.  Coast may directly
or through any affiliated  company  purchase or lease any Collateral at any such
public  disposition,  and if permissible  under  applicable  law, at any private
disposition.  Any sale or other  disposition  of  Collateral  shall not  relieve
Borrower of any liability Borrower may have if any Collateral is defective as to
title or physical condition or otherwise at the time of sale;

            (g) Demand  payment  of, and  collect  any  Receivables  and General
Intangibles  comprising  Collateral  and,  in  connection  therewith,   Borrower
irrevocably  authorizes  Coast  to  endorse  or  sign  Borrower's  name  on  all
collections,  receipts,  instruments and other documents,  to take possession of
and open mail  addressed to Borrower  and remove  therefrom  payments  made with
respect to any item of the Collateral or proceeds thereof,  and, in Coast's sole
discretion,  to grant  extensions of time to pay,  compromise  claims and settle
Receivables and the like for less than face value;

            (h) Demand and receive  possession of any of Borrower's  federal and
state income tax returns and the books and records  utilized in the  preparation
thereof or referring thereto; and

            (i) Require all payments  representing  Coast's  Collateral  and the
proceeds therefrom, be paid to Coast and not to the Senior Notes.

      All  reasonable   attorneys'  fees,  expenses,   costs,   liabilities  and
obligations incurred by Coast (including reasonable attorneys' fees and expenses
incurred in connection with  bankruptcy)  with respect to the foregoing shall be
due from  the  Borrower  to  Coast  on  demand.  Coast  may  charge  the same to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as is applicable to the Receivable  Loans.  Without limiting any of Coast's
rights and remedies, from and after the occurrence and during the continuance of
any Event of Default,  the interest rate applicable to the Obligations  shall be
increased by an additional three percent per annum.

      10.3 Standards for  Determining  Commercial  Reasonableness.  Borrower and
Coast  to the  maximum  extent  permitted  by law  agree  that a sale  or  other
disposition  (collectively,  "Sale") of any  Collateral  which complies with the
following standards will conclusively be deemed to be commercially reasonable:

            (a) Notice of the sale is given to  Borrower at least seven (7) days
prior to the  sale,  and,  in the case of a public  sale,  notice of the sale is
published  at least  seven (7) days  before the sale in a  newspaper  of general
circulation in the county where the sale is to be conducted;

            (b)  Notice  of  the  sale  describes  the  collateral  in  general,
non-specific terms;

            (c) The sale is conducted at a place  designated  by Coast,  with or
without the Collateral being present;

            (d) The sale  commences  at any time between 8:00 a.m. and 6:00 p.m.
Los Angeles, California time;

            (e) Payment of the purchase  price in cash or by cashier's  check or
wire transfer is required; and

            (f) With  respect  to any sale of any of the  Collateral,  Coast may
(but is not obligated to) direct any prospective purchaser to ascertain directly
from Borrower any and all information concerning the same.

      Coast shall be free to employ  other  methods of noticing  and selling the
Collateral, in its discretion, if they are commercially reasonable.

      10.4 Power of Attorney.  Borrower grants to Coast an irrevocable  power of
attorney  coupled with an interest,  authorizing  and  permitting  Coast (acting
through any of its  employees,  attorneys or agents) at any time, at its option,
but without  obligation,  with or without notice to Borrower,  and at Borrower's
expense, to do any or all of the following, in Borrower's name or otherwise, but
Coast  agrees to exercise  the  following  powers in a  commercially  reasonable
manner:

            (a) Execute on behalf of Borrower any  documents  that Coast may, in
its sole  discretion,  deem  advisable in order to perfect and maintain  Coast's
security interest in the Collateral, or in order to exercise a right of Borrower
or Coast,  or in order to fully  consummate  all the  transactions  contemplated
under this Agreement, and all other present and future agreements;

            (b) Upon the occurrence,  and during the continuance of any Event of
Default, execute on behalf of Borrower any document exercising,  transferring or
assigning any option to purchase,  sell or otherwise  dispose of or to lease (as
lessor  or  lessee)  any real or  personal  property  which  is part of  Coast's
Collateral or in which Coast has an interest;

            (c) Upon the occurrence,  and during the continuance of any Event of
Default, execute on behalf of Borrower, any invoices relating to any Receivable;

            (d)  Execute on behalf of  Borrower,  any draft  against any Account
Debtor and any notice to any Account  Debtor,  any proof of claim in bankruptcy,
any  Notice  of Lien,  claim of  mechanic's,  materialman's  or other  lien,  or
assignment or satisfaction of mechanic's, materialman's or other lien;

            (e) Take  control  in any  manner of any cash or  non-cash  items of
payment  or  proceeds  of  Collateral;  endorse  the name of  Borrower  upon any
instruments, or documents,  evidence of payment or Collateral that may come into
Coast's possession;

            (f) Endorse all checks and other  forms of  remittances  received by
Coast;

            (g) Pay, contest or settle any lien, charge,  encumbrance,  security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same;

            (h) Upon the occurrence, and during the continuance, of any Event of
Default,  grant  extensions  of  time  to  pay,  compromise  claims  and  settle
Receivables  and  General  Intangibles  for less than face value and execute all
releases and other documents in connection therewith;

            (i) Pay any sums  required  on  account  of  Borrower's  taxes or to
secure the release of any liens therefor,  or both, which Coast, in the exercise
of its good faith  discretion  and judgment  deems  necessary or  appropriate to
protect its rights, interests, or priorities;

            (j) Settle and adjust,  and give  releases of, any  insurance  claim
that relates to any of the Collateral and obtain payment therefor;

            (k) Instruct any third party having  custody or control of any books
or records  belonging to, or relating to, Borrower to give Coast the same rights
of  access  and other  rights  with  respect  thereto  as Coast  has under  this
Agreement; and

            (l) Take any action or pay any sum required of Borrower  pursuant to
this Agreement and any other present or future agreements.

      Any and  all  sums  paid  and any  and  all  reasonable  costs,  expenses,
liabilities,  obligations  and  reasonable  attorneys'  fees  incurred  by Coast
(including   reasonable  attorneys'  fees  and  expenses  incurred  pursuant  to
bankruptcy)  with respect to the foregoing  shall be added to and become part of
the Obligations,  and shall be payable on demand. Coast may charge the foregoing
to Borrower's loan account and the foregoing  shall  thereafter bear interest at
the same rate  applicable  to the  Receivable  Loans.  In no event shall Coast's
rights  under the  foregoing  power of attorney or any of Coast's  other  rights
under  this  Agreement  be deemed to  indicate  that  Coast is in control of the
business,  management or properties of Borrower.  Borrower shall pay, indemnify,
defend, and hold Coast and each of its officers, directors,  employees, counsel,
agents, and  attorneys-in-fact  (each, an "Indemnified Person") harmless (to the
fullest extent  permitted by law) from and against any and all claims,  demands,
suits, actions, investigations, proceedings, and damages, and all attorneys fees
and  disbursements  and other costs and expenses actually incurred in connection
therewith  (as and when they are  incurred and  irrespective  of whether suit is
brought), at any time asserted against, imposed upon, or incurred by any of them
in  connection  with or as a result of or  related to the  execution,  delivery,
enforcement,  performance,  and  administration  of this Agreement and any other
Loan Documents or the transactions  contemplated herein, and with respect to any
investigation,  litigation,  or proceeding related to this Agreement,  any other
Loan  Document,  or the use of the  proceeds  of the credit  provided  hereunder
(irrespective of whether any Indemnified Person is a party thereto), or any act,
omission,  event  or  circumstance  in  any  manner  related  thereto  (all  the
foregoing, collectively, the "Indemnified Liabilities").  Borrower shall have no
obligation to any Indemnified  Person  hereunder with respect to any Indemnified
Liability  that a court of competent  jurisdiction  finally  determines  to have
resulted  from the gross  negligence or willful  misconduct of such  Indemnified
Person.  This provision  shall survive the termination of this Agreement and the
repayment of the Obligations.

      10.5 Application of Proceeds.  All proceeds  realized as the result of any
sale of the Collateral shall be applied by Coast first to the reasonable  costs,
expenses,  liabilities,  obligations and reasonable  attorneys' fees incurred by
Coast in the exercise of its rights under this Agreement, second to the interest
due upon any of the Obligations,  and third to the principal of the Obligations,
in such order as Coast shall determine in its sole discretion. Any surplus shall
be paid to Borrower or other persons legally  entitled  thereto;  Borrower shall
remain liable to Coast for any deficiency.  If, Coast,  in its sole  discretion,
directly  or  indirectly   enters  into  a  deferred  payment  or  other  credit
transaction  with any purchaser at any sale of Collateral,  Coast shall have the
option,  exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Coast of the cash therefor.

      10.6 Remedies Cumulative. In addition to the rights and remedies set forth
in this Agreement, Coast shall have all the other rights and remedies accorded a
secured party in equity,  under the Code, and under all other  applicable  laws,
and under any other  instrument or agreement  now or in the future  entered into
between Coast and Borrower,  and all of such rights and remedies are  cumulative
and none is exclusive.  Exercise or partial  exercise by Coast of one or more of
its  rights or  remedies  shall not be deemed an  election,  nor bar Coast  from
subsequent  exercise or partial  exercise of any other rights or  remedies.  The
failure or delay of Coast to exercise  any rights or remedies  shall not operate
as a waiver  thereof,  but all rights and remedies  shall continue in full force
and  effect  until  all of the  Obligations  have  been  indefeasibly  paid  and
performed.

11.   GENERAL PROVISIONS.

      11.1 Interest Computation.  In computing interest on the Obligations,  all
checks,  wire transfers and other items of payment  received by Coast (including
proceeds of Receivables  and payment of the Obligations in full) shall be deemed
applied by Coast on account of the  Obligations  three (3)  Business  Days after
receipt by Coast of  immediately  available  funds,  and,  for  purposes  of the
foregoing, any such funds received after 10:30 AM Los Angeles,  California time,
on any day shall be deemed  received on the next  Business  Day.  Coast shall be
entitled  to charge  Borrower's  account  for such  three (3)  Business  Days of
"clearance"  or "float" at the rate(s) set forth in Section 3 of the Schedule on
all checks,  wire  transfers  and other items  received by Coast,  regardless of
whether such three (3) Business Days of "clearance" or "float"  actually  occur,
and shall be deemed to be the  equivalent of charging three (3) Business Days of
interest on such  collections.  This  across-the-board  three (3)  Business  Day
clearance or float charge on all  collections is  acknowledged by the parties to
constitute an integral  aspect of the pricing of Coast's  financing of Borrower.
Except for cash  payments,  Coast  shall not,  however,  be  required  to credit
Borrower's  account  for the  amount  of any  item or form of  payment  which is
unsatisfactory to Coast in its sole discretion,  and Coast may charge Borrower's
loan  account  for the amount of any item of payment  which is returned to Coast
unpaid.

      11.2 Application of Payments.  Subject to Section 7.5 hereof, all payments
with respect to the Obligations  may be applied,  and in Coast's sole discretion
reversed and re-applied,  to the Obligations,  in such order and manner as Coast
shall determine in its sole discretion.

      11.3  Charges to  Accounts.  Coast may, in its  discretion,  require  that
Borrower pay monetary Obligations in cash to Coast, or charge them to Borrower's
Loan  account,  in which event they will bear  interest from the date due to the
date paid at the same rate applicable to the Loans.

      11.4 Monthly  Accountings.  Coast shall provide  Borrower  monthly with an
account of  advances,  charges,  expenses  and  payments  made  pursuant to this
Agreement.  Such  account  shall be deemed  correct,  accurate  and  binding  on
Borrower  and an account  stated  (except for  reverses  and  reapplications  of
payments made and  corrections of errors  discovered by Coast),  unless Borrower
notifies  Coast in writing to the  contrary  within  thirty (30) days after each
account is rendered, describing the nature of any alleged errors or omissions.

      11.5  Notices.  All notices to be given under this  Agreement  shall be in
writing and shall be given either  personally or by reputable  private  delivery
service or by regular  first-class  mail,  facsimile  or  certified  mail return
receipt  requested,  addressed to Coast at the addresses shown in the heading to

this Agreement, or to Borrower c/o VIALOG, 35 New England Business Center, Suite
160,  Hanover,  MA 01810,  or at any other address  designated in writing by one
party to the other party.  Notices to Coast shall be directed to the  Commercial
Finance  Division,  to the  attention  of the  Division  Manager or the Division
Credit Manager.  All notices shall be deemed to have been given upon delivery in
the case of notices  personally  delivered,  faxed (at time of  confirmation  of
transmission),  or at the expiration of one (1) Business Day following  delivery
to the private delivery service,  or two (2) Business Days following the deposit
thereof in the United States mail, with postage prepaid.

      11.6  Severability.  Should any provision of this Agreement be held by any
court of competent  jurisdiction to be void or unenforceable,  such defect shall
not affect the remainder of this  Agreement,  which shall continue in full force
and effect.

      11.7  Integration.  This  Agreement  and such  other  written  agreements,
documents  and  instruments  as may be executed in  connection  herewith are the
final,  entire and complete  agreement  between Borrower and Coast and supersede
all  prior  and  contemporaneous   negotiations  and  oral  representations  and
agreements,  all of which are merged and integrated in this Agreement. There are
no oral understandings,  representations or agreements between the parties which
are not set forth in this Agreement or in other written agreements signed by the
parties in connection herewith.

      11.8  Waivers.  The  failure  of Coast  at any  time or  times to  require
Borrower to strictly  comply with any of the provisions of this Agreement or any
other present or future agreement  between Borrower and Coast shall not waive or
diminish  any  right of Coast  later to demand  and  receive  strict  compliance
therewith.  Any  waiver of any  Default  shall  not  waive or  affect  any other
Default,  whether prior or subsequent,  and whether or not similar.  None of the
provisions  of  this  Agreement  or any  other  agreement  now or in the  future
executed by Borrower and  delivered to Coast shall be deemed to have been waived
by any act or  knowledge  of Coast or its  agents  or  employees,  but only by a
specific  written waiver signed by an authorized  officer of Coast and delivered
to Borrower.  Borrower waives demand,  protest,  notice of protest and notice of
default or  dishonor,  notice of payment and  nonpayment,  release,  compromise,
settlement,  extension or renewal of any commercial paper, instrument,  account,
General  Intangible,  document  or  guaranty  at any time held by Coast on which
Borrower  is or may in any way be  liable,  and  notice of any  action  taken by
Coast, unless expressly required by this Agreement.

      11.9 No Liability for Ordinary  Negligence.  Neither Coast, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing  Coast shall be liable for any claims,  demands,  losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other  party  through the  ordinary  negligence  of Coast,  or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or  representing  Coast,  but  nothing  herein  shall  relieve  Coast  from
liability for its own gross negligence or willful misconduct.

not a  lawsuit  is  filed),  including,  but  not  limited  to,  any  reasonable
attorneys'  fees and costs  (including  reasonable  attorneys' fees and expenses

however,  that  Borrower may not assign or transfer any of its rights under this
Agreement  without  the  prior  written  consent  of Coast,  and any  prohibited

potential  assignees,  participants or syndication  parties to keep confidential
all confidential information relating to Borrower or its business. To the extent
that Coast assigns its rights and obligations hereunder to a third Person, Coast
thereafter shall be released from such assigned obligations to Borrower.

in this  Agreement  for  convenience.  Borrower and Coast  acknowledge  that the

                                        outstanding  not to exceed the lesser of
                                        a  total  of  Fifteen   Million  Dollars
                                        ($15,000,000.00)   at   any   one   time
                                        outstanding (the Maximum Dollar Amount),
                                        or the sum of (a), (b) and (c) below:

                                        (a)   Receivable   Loans  up  to  eighty
                                        percent   (80%)   of   the   amount   of
                                        Borrower's   Eligible   Receivables  (as
                                        defined in Section 1 of the  Agreement).
                                        The advance rate on the Receivable Loans
                                        may be  increased,  in Coast's  sole and
                                        absolute discretion, to an amount not to
                                        exceed  eighty-five   percent  (85%)  of
                                        Borrower's   Eligible   Receivables   if

                                        discretion,  determines that dilution of
                                        Receivables  has been and is, in Coast's
                                        opinion,  likely to  continue  at a rate
                                        that is five percent (5%) or less;  plus
 
                                        (b) Term  Loan  (the  "Term  Loan") in a

                                        total  amount  not to exceed  the lesser

                                        by or otherwise acceptable to Coast that

                                        the advance rate for the particular used

                                        provided  such  equipment  was new  when
                                        purchased and such consideration will be

                                        termination  as  provided in Section 9.2

                                               Dollars  ($50,000.00) or more, or

                                               As    of    closing,     Borrower
                                               represents  that the only  future
                                               claim  is as  follows:  A  former
                                               employee  of  Conference   Source
                                               International,  Inc.  ("CSI") has
                                               claimed  that he may be  entitled
                                               to 5% of the  stock of CSI  based
                                               on an  unsigned  paper  outlining
                                               possible  employment terms. CSI's
                                               position   is   that   the   only
                                               agreements   with  such  employee
                                               were set forth in two  successive
                                               executed  employment  agreements,
                                               each  of  which  had  a  specific
                                               provision that such agreement was
                                               inclusive  as  to  the  terms  of
                                               employment.   CSI  believes  that
                                               such claim is without merit.
