GUARANTOR ________________________________________
By________________________________________________






                               CONTINUING GUARANTY


     For Valuable Consideration,  the receipt and sufficiency of which is hereby
acknowledged,  the undersigned, for themselves, their heirs, executors, personal
representatives,  successors and assigns  (individually  called  "Guarantor" and
collectively called  "Guarantors")  jointly and severally and in solido,  hereby
unconditionally   guarantee  to   Associates   Capital   Services   Corporation,
- ----------------------  its  successors,  endorsees  and assigns,  (collectively
called "Associates") that Multi-Link Communications,  Inc. (the "Company), whose
address is 811 Lincoln Street, Denver, Colorado 80203,
                         (Part to be Guaranteed) Debtor

shall  promptly  and fully  perform,  pay and  discharge  all of its present and
future liabilities,  obligations and indebtedness to Associates,  whether direct
or indirect,  joint or several,  absolute or  contingent,  secured or unsecured,
matured or  unmatured,  and  whether  originally  contracted  with or  otherwise
acquired by Associates (all of which  liabilities,  obligations and indebtedness
are  herein  individually  and  collectively  called the  "Indebtedness").  This
Guaranty  is an  absolute  and  unconditional  guarantee  of payment  and not of
collectibility.  The liability of each Guarantor hereunder is not conditional or
contingent upon the genuineness,  validity, sufficiency or enforceability of the
indebtedness  or any  instruments,  agreements or chattel paper related  thereto
(collectively  called  "Agreements")  or any  security  or  collateral  therefor
(collectively  called  "Security") or the pursuit by Associates of any rights or
remedies which it now has or may hereafter have. If the Company fails to pay the
indebtedness promptly as the same becomes due, or otherwise fails to perform any
obligation  under any of the Agreements,  each Guarantor agrees to pay on demand
the entire  indebtedness  and all losses,  costs,  attorney's  fees and expenses
which may be suffered by Associates  by reason of the  Company's  default or the
default  of any  Guarantor  hereunder,  and  agrees to be bound by and to pay on
demand  any  deficiency  established  by the  sale of any of the  Agreements  or
Security,  all without relief from valuation and  appraisement  laws and without
requiring  Associates  to (i) proceed  against the Company by suit or otherwise,
(ii) foreclose,  proceed against,  liquidate or exhaust any of the Agreements or
Security,  or (iii) exercise,  pursue or enforce any right or remedy  Associates
may have against the Company,  any  co-Guarantor  (whether  hereunder or under a
separate  instrument)  or any other party.  Each  Guarantor  agrees  that:  this
Guaranty  shall  not  be  discharged  or  affected  by any  circumstances  which
constitute  a legal or equitable  discharge of a Guarantor or surety,  or by the
death  of any  Guarantor;  the  records  of  Associates  shall  be  received  as
conclusive  evidence of the amount of the indebtedness at any time owing; one or
more successive or concurrent suits may be brought and maintained against any or
all of the Guarantors,  at the option of Associates,  with or without joinder of
the Company or any of the other  Guarantors as parties  thereto;  such Guarantor
will not avail  itself of any  defense  whatsoever  which the  Company  may have
against  Associates,  other  than full  payment  of the  indebtedness;  and such
Guarantor  will not seek a change  of venue  from any  jurisdiction  or court in
which any action, proceeding or litigation is commenced.

     EACH GUARANTOR  HEREBY WAIVES NOTICE OF ANY ADVERSE CHANGE IN THE COMPANY'S
CONDITION OR OF ANY OTHER FACT WHICH MIGHT MATERIALLY  INCREASE SUCH GUARANTOR'S
RISK,  WHETHER OR NOT ASSOCIATES HAS KNOWLEDGE OF THE SAME.  EACH GUARANTOR ALSO
HEREBY  WAIVES ANY CLAIM,  RIGHT OR REMEDY WHICH SUCH  GUARANTOR MAY NOW HAVE OR
HEREAFTER  ACQUIRE  AGAINST THE COMPANY  THAT ARISES  HEREUNDER  AND/OR FROM THE
PERFORMANCE BY ANY GUARANTOR HEREUNDER INCLUDING, WITHOUT LIMITAITON, ANY CLAIM,
REMEDY  OR  RIGHT  OF  SUBROGATION,  REIMBURSEMENT,  EXONERATION,  CONTRIBUTION,
INDEMNIFICATION,  OR PARTICIPATION  IN ANY CLAIM,  RIGHT OR REMEDY OF ASSOCIATES
AGAINST  THE  COMPANY OR ANY  SECURITY  WHICH  ASSOCIATES  NOW HAS OR  HEREAFTER
ACQUIRES;  WHETHER OR NOT SUCH CLAIM,  RIGHT OR REMEDY  ARISES IN EQUITY,  UNDER
CONTRACT, BY STATUTE, UNDER COMMON LAW OR OTHERWISE.




     No termination  hereof shall be effective  until the Guarantors  deliver to
Associates a written  notice  signed by them  electing not to guarantee  any new
extension of credit that may be granted by  Associates  to the Company after its
receipt of such notice,  but such notice shall not affect the  obligation of the
guarantors  hereunder as to any and all  indebtedness  existing at the time such
notice is received. Each Guarantor hereby waives (i) notice of acceptance hereof
and notice of  extensions of credit given by Associates to the Company from time
to time; (ii) presentment, demand, protest, and notice of non-payment or protest
as to any note or other evidence of indebtedness signed,  accepted,  endorsed or
assigned to Associates by the Company;  (iii) all exemptions and homestead laws:
(iv) any other  demands and notices  required by law; and (v) any right to trial
by jury.  Associates may at any time and from time to time, without notice to or
the consent of any Guarantor,  and without affecting or impairing the obligation
of any Guarantor  hereunder;  (a) renew,  extend or refinance any part or all of
the indebtedness of the Company or any indebtedness of its customers,  or of any
co-Guarantor  (whether  hereunder or under a separate  instrument)  or any other
party;  (b) accept partial  payments of the indebtedness and apply such payments
to any part of the  indebtedness;  (c) settle,  release (by  operation of law or
otherwise),  compound,  compromise,  collect or liquidate, in any manner, any of
the indebtedness, any Security, or any indebtedness of any co-Guarantor (whether
hereunder or under a separate instrument) or any other party; (d) consent to the
transfer  of any  Security;  (e)  bid  and  purchase  at any  sale of any of the
Agreements  or  Security;  and (f)  exercise  any and all  rights  and  remedies
available to  Associates  by law or agreement  even if the exercise  thereof may
affect,  modify or eliminate  any rights or remedies  which a Guarantor may have
against the  Company.  Each  Guarantor  shall  continue to be liable  under this
Guaranty,  the  provisions  hereof  shall  remain in full force and effect,  and
Associates   shall  not  be  stopped  from  exercising  any  rights   hereunder,
notwithstanding (i) Associates waiver of or failure to enforce any of the terms,
covenants or conditions contained in any of the Agreements;  (ii) any release of
or failure on the part of  Associates  to perfect  any  security  interest in or
foreclose,  proceed  against,  or exhaust,  any  Security;  or (iii)  Associates
failure to take new,  additional  or substitute  security or collateral  for the
indebtedness.

     Each Guarantor  agrees that  Associates may bring any legal  proceedings it
deems necessary to enforce any or all of such Guarantor's  obligations hereunder
in any  court  in the  State  in  which  Associates'  office  administering  the
indebtedness is located;  and service of process may be made upon such Guarantor
by mailing a copy of the summons to such  Guarantor at its address last known to
Associates.  All  rights and  remedies  of  Associates  are  cumulative  and not
alternative.  Each  provision of this Guaranty is intended to be severable.  Any
term or provision  hereof  declared to be contrary to,  prohibited by or invalid
under  applicable laws or regulations  shall be inapplicable  and deemed omitted
herefrom, but shall not invalidate the remaining terms and provisions hereof.

     IN WITNESS WHEREOF, the Guarantors have executed this Guaranty on
