                                    GUARANTY

          This Guaranty (this  "Guaranty") is  made and  executed as of April 5,
2000 by eGLOBE,  INC., a Delaware  corporation (the "Parent"),  eGlobe Financing
Corporation,  a Delaware corporation and a wholly owned subsidiary of the Parent
("eGlobe Financing"),  IDX Financing  Corporation,  a Delaware corporation and a
wholly owned subsidiary of IDX International, Inc., a wholly owned subsidiary of
the Parent ("IDX  Financing"),  and Telekey  Financing  Corporation,  a Delaware
corporation  and a wholly  owned  subsidiary  of Telekey,  Inc.,  a wholly owned
subsidiary of the Parent ("Telekey Financing") (hereinafter  collectively called
the "Guarantor"), in favor of SPECIAL INVESTMENT RISKS, LLC, a limited liability
company organized under the laws of Nevada (hereinafter called the "Investor").

          WHEREAS,  on December 2, 1999,  Coast  International,  Inc.  ("Coast")
merged  with  and  into   eGlobe/Coast,   Inc.,  a  Delaware   corporation  (the
"Borrower"),  pursuant  to the terms of an  Agreement  and Plan of Merger  dated
November 29, 1999 among Parent,  the  Borrower,  Coast and the  stockholders  of
Coast, as a result of which the Borrower was the surviving  company and remained
a wholly owned subsidiary of Parent (the "Coast Merger");

          WHEREAS, prior to the Coast Merger and pursuant to a certain Revolving
Credit  Note  Agreement  dated  March  5,  1999,  Investor  has lent to Coast an
aggregate  principal  amount of  $3,250,000  as evidenced  by a promissory  note
("Special Investment Note");

          WHEREAS,  in connection with the consummation of the Coast Merger, the
Borrower assumed Coast's  obligations to repay all amounts due and payable under
the Special Investment Note, whether at maturity,  by acceleration or otherwise,
in accordance with the terms of the Special Investment Note;

          WHEREAS,  the Investor  desires to obtain from the  Guarantor  and the
Guarantor  desires to provide to the Investor the guaranty  more fully set forth
below;

          NOW, THEREFORE, in consideration of the foregoing,  and for other good
and  valuable  consideration,  the receipt and  sufficiency  of which are hereby
acknowledged, the Guarantor hereby agrees as follows:

          1. The Guarantor hereby unconditionally guarantees to the Investor the
due,  timely  and full  payment  and  satisfaction  by the  Borrower  of all its
obligations  that arise under the Special  Investment  Note on or after the date
hereof,  including,  without  limitation,  payment  in full,  when  due,  of the
indebtedness  evidenced by the Special  Investment  Note and the due, timely and
complete  performance by the the Borrower of all of its other agreements,  terms
and covenants under the Special  Investement Note,  provided that a violation of
such

<PAGE>

other agreements, terms and covenants would constitute an event of default under
the Special Investment Note (collectively,  the "Guaranteed  Obligations").  The
obligations of the Guarantor  hereunder are absolute and  unconditional and this
Guaranty is a  continuing  guaranty of payment and  performance  by the Borrower
which will not terminate until the Guaranteed  Obligations  shall have been paid
and performed in full.

          2. The Investor may, at the Investor's option, proceed to enforce this
Guaranty  directly against the Guarantor  without first  proceeding  against the
Borrower or any other person liable for payment or performance under the Special
Investment  Note or this  Guaranty  and  without  first  proceeding  against  or
exhausting  any  collateral  now or  hereafter  held by the  Investor  to secure
payment  or  performance  under  the  Special  Investment  Note or the  Security
Agreement securing this Guaranty (the "Security Agreement").

          3. The Guarantor waives  diligence,  presentment,  protest,  notice of
dishonor, demand for payment, notice of nonpayment or nonperformance,  notice of
acceptance  of this  Guaranty,  notice of  intention  to  accelerate,  notice of
acceleration,  and all  other  notices  of any  nature  in  connection  with the
exercise of the  Investor's  rights  under the Special  Investment  Note or this
Guaranty.  Performance by the Guarantor hereunder will not entitle the Guarantor
to  any   payment   by  the   Borrower   under  any   claim  for   contribution,
indemnification,  subrogation or otherwise, and the Guarantor hereby irrevocably
waives and relinquishes any and all rights to recover from the Borrower, whether
by way of subrogation, reimbursement, indemnity, contribution, or otherwise, any
amounts  paid by the  Guarantor  under  this  Guaranty  until  such  time as the
Guaranteed Obligations have been paid and performed in full.

          4.  The  Guarantor  hereby  consents  and  agrees  that  renewals  and
extensions  of time of  payment,  surrender,  release,  exchange,  substitution,
dealing with or taking of additional  collateral security,  taking or release of
other  guarantees,  abstaining  from taking  advantage of or realizing  upon any
collateral  security or other  guarantees and any and all other  forbearances or
indulgences  granted by the  Investor to the  Borrower or any other party may be
made,  granted and effected by the Investor  without notice to the Guarantor and
without in any manner affecting the Guarantor's liability hereunder.

          5. Nothing herein  contained will limit the Investor in exercising any
rights held under the Special Investment Note or the Security Agreement.  In the
event of any default under the Special  Investment Note, the Security  Agreement
or this Guaranty,  the Investor will be entitled selectively and successively to
enforce  any  one or more  of the  rights  held  by the  Investor  hereunder  or
thereunder  and such  action will not be deemed a waiver of any other right held
by the Investor.  All of the remedies of the Investor under this  Guaranty,  the
Special  Investment  Note and the  Security  Agreement  are  cumulative  and not

                                       2
<PAGE>

alternative. If the Investor elects to foreclose any lien created by the Special
Investment  Note or the  Security  Agreement,  the  Investor  is  authorized  to
purchase for the Investor's account all or any part of the collateral covered by
such lien at public or private sale.

          6. In the event that a petition in bankruptcy  for an  arrangement  or
reorganization  of the Borrower under any bankruptcy law or for the  appointment
of a receiver for the Borrower or any of its property is filed by the  Borrower,
or if the  Borrower  shall make an  assignment  for the benefit of  creditors or
shall become insolvent,  all indebtedness of the Borrower shall, for the purpose
of  this  Guaranty,  be  deemed  at  the  Investor's  election  to  have  become
immediately due and payable.

          7. The Guarantor further agrees to pay the Investor any and all costs,
expenses  and  reasonable  attorneys'  fees paid or incurred by the  Investor in
enforcing or endeavoring to enforce this Guaranty.

          8. If any provision of this Guaranty is held to be invalid, illegal or
unenforceable  in any respect for any reason,  such  invalidity,  illegality  or
unenforceability  will not affect any other provisions herein contained and such
other  provisions  will remain in full force and effect.  This  Guaranty will be
binding on the  Guarantor  and all  successors  and assigns of the Guarantor and
will inure to the benefit of the Investor and all  successors and assigns of the
Investor.  The Guarantor consents to the assignment of all or any portion of the
rights of the Investor hereunder in connection with any assignment of the rights
of the  Investor  under  the  Special  Investment  Note,  without  notice to the
Guarantor.

          9. If any payment or thing of value should be received and accepted by
the Investor in payment of any  indebtedness or obligation of the Borrower under
the Special Investment Note and it should subsequently be determined or adjudged
that such payment be void or voidable  under any law or statute now or hereafter
in  effect,  the  receipt  of such  payment  by the  Investor  shall,  as to the
Guarantor,  be deemed a  provisional  receipt and if any such payment  should be
avoided or set aside  under any such law or statute the  Guarantor  shall be and
remain liable to the Investor in respect thereof as if such payment had not been
received  by the  Investor,  notwithstanding  any release or  discharge  of this
Guaranty  issued or granted by the Investor in the belief or assumption that its
receipt of such  payment was  absolute  and not subject to any  avoidance or set
aside.

          10. The terms "the  Guarantor"  and "the  Borrower"  and any  pronouns
referring thereto as used herein shall be construed in the masculine,  feminine,
neuter, singular or plural as the context may require.

          11. The  obligations  of each of the parties hereto which are included
in the defined term "the Guarantor" are joint and several.

          12.  This  Agreement  may not be amended  except by an  instrument  in
writing signed by the parties hereto.

          13. All corporate law matters  arising under this  Agreement  shall be
governed by and construed in accordance  with the laws of the State of Delaware,
and all other  matters  arising  under this  Agreement  shall be governed by and
construed  in  accordance  with the laws of the  State of  Texas,  in each  case
regardless of the laws that might otherwise govern under  applicable  principles
of conflicts of law.  Each of the parties  consents to the  jurisdiction  of the
federal courts whose  districts  encompass any part of the State of Texas or the
state courts of the State of Texas in connection  with any dispute arising under
this  Agreement and hereby waives,  to the maximum extent  permitted by law, any
objection,  including  any  objection  based on  forum  non  conveniens,  to the
bringing of any such proceeding in such jurisdictions.

          14.  This  Agreement  may be  executed  and  delivered  in one or more
counterparts, and by the different parties hereto in separate counterparts, each
of which when executed and  delivered  shall be deemed to be an original but all
of which taken together shall constitute one and the same agreement.
