Guarantor hereby declares and agrees that this Guaranty is and shall continue to
be a several obligation, shall be a continuing guaranty and shall be operative
and binding, and that the Guarantor shall have no right of subrogation with
respect to this Guaranty until the Obligations have been paid or otherwise
satisfied in full.

         3. GUARANTY FINAL. Upon the execution and delivery of this Guaranty to
the Administrative Agent, this Guaranty shall be deemed to be finally executed
and delivered by the Guarantor and shall not be subject to or affected by any
promise or condition affecting or limiting the Guarantor's liability, and no
statement, representation, agreement or promise on the part of the Lenders and
the Administrative Agent, the Borrower, or any of them, or any officer, employee

<PAGE>

induced the making hereof or shall be deemed in any way to affect the
Guarantor's liability hereunder.

         4. REPRESENTATIONS AND WARRANTIES. The Guarantor hereby agrees,
represents and warrants, upon the Agreement Date, in favor of the Administrative
Agent and each Lender, that:

         (a) The Guarantor is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware. The Guarantor has the
corporate power and authority to own its properties and to carry on its business
as now being and as proposed hereafter to be conducted. The Guarantor and each
Affiliate Guarantor are duly qualified, in good standing and authorized to do
business in each jurisdiction in which the character of their respective
properties or the nature of their respective businesses requires such
qualification or authorization, except where failure to be so qualified, in the
aggregate, could not reasonably be expected to have a Materially Adverse Effect.

         (b) The Guarantor has the corporate power and has taken all necessary
corporate action to authorize it to borrow hereunder, to execute, deliver and
perform this Agreement and each of the other Loan Documents to which it is a
party in accordance with their respective terms, and to consummate the
transactions contemplated hereby and thereby. This Agreement has been duly
executed and delivered by the Guarantor and is, and each of the other Loan
Documents to which the Guarantor is party is, a legal, valid and binding
obligation of the Guarantor enforceable against the Guarantor in accordance with
its terms, subject, as to enforcement of remedies, to applicable bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and similar laws
affecting creditors' rights and remedies generally, and subject, as to
enforceability, to general principles of equity.

         (c) To the extent that any Affiliate Guarantors exist, the Guarantor
has the unrestricted right to vote the issued and outstanding equity of the
Affiliate Guarantors owned by the Guarantor and such equity of such Affiliate
Guarantors has been duly authorized and issued and is fully paid and
nonassessable. Each Affiliate Guarantor, if any, has the power and has taken all
necessary action to authorize it to execute, deliver and perform each of the
Loan Documents to which it is a party in accordance with their respective terms
and to consummate the transactions contemplated by this Agreement and by such
Loan Documents. Each of the Loan Documents to which any Affiliate Guarantor is
party is a legal, valid and binding obligation of such Affiliate Guarantor
enforceable against such Affiliate Guarantor in accordance with its terms,
subject, as to enforcement of remedies, to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally, and subject, as to enforceability, to
general principles of equity. The Guarantor's ownership interest in each
Affiliate Guarantor represents a direct or indirect controlling interest of such
Affiliate Guarantor for purposes of directing or causing the direction of the
management and policies of each Affiliate Guarantor.

         (d) The Guarantor and each of the Affiliate Guarantors have secured all
material Necessary Authorizations and all such Necessary Authorizations are in
full force and effect. No

                                      - 5 -

<PAGE>

material Necessary Authorization is the subject of any pending or, to the
best of the Guarantor's knowledge, threatened revocation.

         (e) The Guarantor and each of the Affiliate Guarantors are in
compliance with all Applicable Law, except where the failure to be in compliance
would not individually or in the aggregate have a Materially Adverse Effect.

         (f) As of the Agreement Date, the Guarantor and each of the Affiliate
Guarantors have good, legal and marketable title to, or a valid leasehold
interest in, all of its material assets. None of the properties or assets of the
Guarantor or any of the Affiliate Guarantors is subject to any Liens, except for
Permitted Liens. Except for financing statements evidencing Permitted Liens, no
financing statement under the Uniform Commercial Code as in effect in any
jurisdiction and no other filing which names the Guarantor or any of the
Affiliate Guarantors as debtor or which covers or purports to cover any of the
assets of the Guarantor or any of the Affiliate Guarantors is currently
effective and on file in any state or other jurisdiction, and neither the
Guarantor nor any of the Affiliate Guarantors has signed any such financing
statement or filing or any security agreement authorizing any secured party
thereunder to file any such financing statement or filing.

         (g) As of the date hereof, except as set forth on SCHEDULE 3 attached
hereto, there is no action, suit, proceeding or investigation pending against,
or, to the knowledge of the Guarantor, threatened against or in any other manner
relating adversely to, the Guarantor or any of the Affiliate Guarantors or, to
the knowledge of the Guarantor, any of their respective properties, in any court
or before any arbitrator of any kind or before or by any governmental body. No
action, suit, proceeding or investigation (i) calls into question the validity
of this Agreement or any other Loan Document or, (ii) individually or
collectively, involves the possibility of any judgment or liability not fully
covered by insurance which, if determined adversely to the Guarantor or any of
the Affiliate Guarantors, would have a Materially Adverse Effect.

         (h) All material federal, state and other tax returns of the Guarantor
and each of the Affiliate Guarantors required by law to be filed have been duly
filed and all federal, state and other taxes, including, without limitation,
withholding taxes, assessments and other governmental charges or levies required
to be paid by the Guarantor or any Affiliate Guarantor or imposed upon the
Guarantor or any Affiliate Guarantor or any of their respective properties,
income, profits or assets, which are due and payable, have been paid, except any
such taxes (i) (x) the payment of which the Guarantor or any Affiliate Guarantor
is diligently contesting in good faith by appropriate proceedings, (y) for which
adequate reserves have been provided on the books of the Guarantor or the
Affiliate Guarantor involved, and (z) as to which no Lien other than a Permitted
Lien has attached and no foreclosure, distraint, sale or similar proceedings
have been commenced, or (ii) which may result from audits not yet conducted. The
charges, accruals and reserves on the books of the Guarantor and each Affiliate
Guarantor in respect of taxes are, in the judgment of the Guarantor, adequate.

                                      - 6 -

<PAGE>

         (i) There has occurred no event, condition or other change since
December 31, 1998 which has had, or which could reasonably be expected to have,
a Materially Adverse Effect.

         (j) The Guarantor and the Affiliate Guarantors are in compliance in all
respects with all of the material provisions of their respective certificates or
articles of incorporation and by-laws, as the case may be, and no event has
occurred or failed to occur (including, without limitation, any matter which
could create a Default hereunder by cross-default) which has not been remedied
or waived, the occurrence or non-occurrence of which constitutes, (i) a Default
or (ii) a material default by the Guarantor or any Affiliate Guarantor under any
indenture, agreement or other instrument relating to Indebtedness of the
Guarantor or any Affiliate Guarantors in the amount of $1,000,000.00 or more in
the aggregate (other than Indebtedness owing to the Borrower or its Subsidiaries
in connection with any loan made pursuant to Section 7.6(b) of the Loan
Agreement), any material license, or any judgment, decree or order to which the
Guarantor or any Affiliate Guarantor is a party or by which the Guarantor or any
Affiliate Guarantor or any of their respective properties may be bound or
affected.

         (k) The Security Interest granted under the Parent Security Agreement
and any Affiliate Security Agreement is a valid and, upon filing of appropriate
Uniform Commercial Code financing statements and/or mortgages, will be a
perfected first priority security interest in the Collateral in favor of the
Administrative Agent, for the benefit of itself and the Lenders, securing, in
accordance with the terms of such Security Documents, the Obligations, and the
Collateral is subject to no Liens other than Permitted Liens. The Liens created
by the Security Documents to which the Guarantor and the Affiliate Guarantors,
or any of them, are a party are enforceable as security for the Obligations in
accordance with their terms with respect to the Collateral subject, as to
enforcement of remedies, to the following qualifications: (i) an order of
specific performance and an injunction are discretionary remedies and, in
particular, may not be available where damages are considered an adequate remedy
at law; (ii) enforcement may be limited by bankruptcy, insolvency, liquidation,
reorganization, reconstruction and other similar laws affecting enforcement of
creditors' rights generally (insofar as any such law relates to the bankruptcy,
insolvency or similar event of the Guarantor or any Affiliate Guarantor, as the
case may be); (iii) enforcement may require FCC and state agency approvals as to
any transfer of control of the Affiliate Guarantors and as to exercise of any
rights with respect to the Licenses; and (iv) enforcement may be subject to
limitations set forth in the Communications Act and regulations thereunder and
state regulatory and comparable law applicable to telecommunications and related
companies and regulations thereunder.

         (l) Except as described on SCHEDULE 4 attached hereto, and except for
any Indebtedness owed to the Borrower and its Subsidiaries in connection with
any loan made by the Borrower or any of its Subsidiaries pursuant to Section
7.6(b) of the Loan Agreement, neither the Guarantor nor any Affiliate Guarantor
has outstanding, as of the Agreement Date, any Indebtedness for Money Borrowed.

         (m) As of the Agreement Date and after giving effect to the
transactions contemplated by the Loan Documents: (i) the property of the
Guarantor, at a fair valuation, will exceed its debt; (ii) the capital of the
Guarantor will not be unreasonably small to conduct its business;

                                      - 7 -

<PAGE>

(iii) the Guarantor will not have incurred debts, or have intended to incur
debts, beyond its ability to pay such debts as they mature; and (iv) the
present fair salable value of the assets of the Guarantor will be greater
than the amount that will be required to pay its probable liabilities
(including debts) as they become absolute and matured. For purposes of this
Section 4(m), "debt" means any liability on a claim, and "claim" means (i)
the right to payment, whether or not such right is reduced to judgment,
liquidated, unliquidated, fixed, contingent, matured, unmatured, undisputed,
legal, equitable, secured or unsecured, or (ii) the right to an equitable
remedy for breach of performance if such breach gives rise to a right to
payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, undisputed, secured or
unsecured.

         (n) The Guarantor and the Affiliate Guarantors have reviewed the areas
within their business and operations which could be adversely affected by, and
have developed or are developing a program to address on a timely basis, the
"YEAR 2000 PROBLEM" (that is, the risk that computer applications used by the
Guarantor and the Affiliate Guarantors may be unable to recognize and perform
properly date-sensitive functions involving certain dates prior to and any date
after December 31, 1999). Based on such review and program, the Guarantor
reasonably believes that the Year 2000 Problem will not have a Materially
Adverse Effect.

         5. COVENANTS. So long as any of the Obligations is outstanding and
unpaid or the Lenders have an obligation to fund Advances under the Loan
Agreement (whether or not the conditions to borrowing have or can be fulfilled),
and unless the Required Lenders, or such greater number of Lenders as may be
expressly provided herein, shall otherwise consent in writing:

         (a) Except as permitted under Section 5(o) hereof, the Guarantor will,
and will cause each Affiliate Guarantor to:

                  (i)  preserve and maintain its existence, and its material
         rights, franchises, licenses and privileges in the state of its
         incorporation, including, without limiting the foregoing, all other
         Necessary Authorizations; and

                  (ii) qualify and remain qualified and authorized to do
         business in each jurisdiction in which the character of its properties
         or the nature of its business requires such qualification or
         authorization, except for such failure to so qualify and be so
         authorized as could not reasonably be expected to have a Materially
         Adverse Effect.

         (b) The Guarantor will, and will cause each Affiliate Guarantor to,
maintain or cause to be maintained in the ordinary course of business in good
repair, working order and condition (reasonable wear and tear excepted) all
material properties used in their respective businesses (whether owned or held
under lease), other than obsolete equipment or unused assets and from time to
time make or cause to be made all needed and appropriate repairs, renewals,
replacements, additions, betterments and improvements thereto.

         (c) The Guarantor will, and will cause each Affiliate Guarantor to:

                                      - 8 -

<PAGE>

                  (i)   Maintain insurance including, but not limited to,
business interruption coverage and public liability coverage insurance from
responsible companies in such amounts and against such risks to the Guarantor
and each Affiliate Guarantor as is prudent for similarly situated companies
engaged in similarly situated industries.

                  (ii)  Keep their respective assets insured by insurers on

<PAGE>

manner any of the provisions, terms, or conditions of the Guaranteed
Agreements, all as the Lenders and the Administrative Agent, or any of them,
may consider expedient or appropriate in their sole discretion. Without
limiting the generality of the foregoing, or of Section 6 hereof, it is
understood that the Lenders and the Administrative Agent, or any of them,
may, without exonerating or releasing the Guarantor, give up, or modify or
abstain from perfecting or taking advantage of any security for the
Obligations and accept or make any compositions or arrangements, and realize
upon any security for the Obligations when, and in such manner, as the
Lenders and the Administrative Agent, or any of them, may deem expedient,
consistent with the Loan Agreement, all without notice to the Guarantor,
except as required by Applicable Law.

         8. GUARANTY UNCONDITIONAL. The Guarantor acknowledges and agrees that
no change in the nature or terms of the Obligations or any of the Guaranteed
Agreements, or other agreements, instruments or contracts evidencing, related to
or attendant with the Obligations (including any novation), nor any
determination of lack of enforceability thereof, shall discharge all or any part
of the liabilities and obligations of the Guarantor pursuant to this Guaranty;
it being the purpose and intent of the Guarantor, the Lenders and the
Administrative Agent that the covenants, agreements and all liabilities and
obligations of the Guarantor hereunder are absolute, unconditional and
irrevocable under any and all circumstances. Without limiting the generality of
the foregoing, the Guarantor agrees that until each and every one of the
covenants and agreements of this Guaranty is fully performed, the Guarantor's
undertakings hereunder shall not be released, in whole or in part, by any action
or thing which might, but for this paragraph of this Guaranty, be deemed a legal
or equitable discharge of a surety or guarantor, or by reason of any waiver,
omission of the Lenders and the Administrative Agent, or any of them, or their
failure to proceed promptly or otherwise, or by reason of any action taken or
omitted by the Lenders and the Administrative Agent, or any of them, whether or
not such action or failure to act varies or increases the risk of, or affects
the rights or remedies of, the Guarantor or by reason of any further dealings
between the Borrower, the Lenders and the Administrative Agent, or any of them,
or any other guarantor or surety, and the Guarantor, to the extent permitted by
Applicable Law, hereby expressly waives and surrenders any defense to its
liability hereunder, or any right of counterclaim or offset of any nature or
description which it may have or which may exist based upon, and shall be deemed
to have consented to, any of the foregoing acts, omissions, things, agreements
or waivers.

         9. SET-OFF. The Lenders and the Administrative Agent, or any of them,
may, without demand or notice of any kind upon or to the Guarantor, at any time
or from time to time when any amount shall be due and payable hereunder by the
Guarantor, if the Borrower shall not have timely paid its Obligations, set off
and appropriate any property, balances, credit accounts or moneys of the
Guarantor (other than those held in a trust) in the possession of the Lenders
and the Administrative Agent, or any of them, or under the control of any of
them for any purpose, which property, balances, credit accounts or moneys shall
thereupon be turned over and remitted to the Administrative Agent, to be held
and applied to the Obligations by the Administrative Agent in accordance with
the Loan Agreement, and the Guarantor hereby grants to the Lenders and the
Administrative Agent, a security interest in all such property. The
Administrative Agent shall give written notice to the Borrower of the exercise
of any of the foregoing rights within one (1) Business Day following the
exercise thereof.

                                      - 14 -

<PAGE>

         10. BANKRUPTCY. Upon the bankruptcy or winding up or other distribution
of assets of the Borrower or any Subsidiary of the Borrower or of any surety or
guarantor for the Obligations, the rights of the Lenders and the Administrative
Agent, or any of them, against the Guarantor shall not be affected or impaired
by the omission of the Lenders and the Administrative Agent, or any of them, to
prove its or their claim, as appropriate, or to prove its or their full claim,
as appropriate, and the Lenders and the Administrative Agent may prove such
claims as they see fit and may refrain from proving any claim and in their
respective discretion they may value as they see fit or refrain from valuing any
security held by the Lenders and the Administrative Agent, or any of them,
without in any way releasing, reducing or otherwise affecting the liability to
the Lenders and the Administrative Agent of the Guarantor.

         11. APPLICATION OF PAYMENTS. Any amount received by the Lenders and the
Administrative Agent, or any of them, from whatsoever source and applied toward
the payment of the Obligations shall be applied in such order of application as
is set forth in the Loan Agreement.

         12. WAIVERS BY GUARANTOR. The Guarantor hereby expressly waives, to the
extent permitted by Applicable Law: (a) notice of acceptance of this Guaranty,
(b) notice of the existence or creation of all or any of the Obligations, (c)
presentment, demand, notice of dishonor, protest, and all other notices
whatsoever, (d) all diligence in collection or protection of or realization upon
the Obligations or any part thereof, any obligation hereunder, or any security
for any of the foregoing and (e) all rights of subrogation, indemnification,
contribution and reimbursement against the Borrower, all rights to enforce any
remedy the Lenders and the Administrative Agent, or any of them, may have
against the Borrower and any benefit of, or right to participate in, any
collateral or security now or hereinafter held by the Lenders and the
Administrative Agent, or any of them, in respect of the Obligations, until
payment in full of the Obligations. Any money received by the Guarantor in
violation of this Section 12 shall be held in trust by the Guarantor for the
benefit of the Lenders and the Administrative Agent. If a claim is ever made
upon the Lenders and the Administrative Agent, or any of them, for the repayment
or recovery of any amount or amounts received by any of them in payment of any
of the Obligations and such Person repays all or part of such amount by reason
of (a) any judgment, decree, or order of any court or administrative body having
jurisdiction over such Person or any of its property, or (b) any good faith
settlement or compromise of any such claim effected by such Person with any such
claimant, including, without limitation, the Borrower, then in such event the
Guarantor agrees that any such judgment, decree, order, settlement, or
compromise shall be binding upon the Guarantor, notwithstanding any revocation
hereof or the cancellation of any promissory note or other instrument evidencing
any of the Obligations, and the Guarantor shall be and remain obligated to such
Person hereunder for the amount so repaid or recovered to the same extent as if
such amount had never originally been received by such Person.

         13. ASSIGNMENT BY THE LENDERS AND THE ADMINISTRATIVE AGENT. To the
extent permitted under the Loan Agreement, the Lenders and the Administrative
Agent may each, and without notice of any kind, except as otherwise required by
the Loan Agreement, sell, assign or transfer all or any of the Obligations, and
in such event each and every immediate and successive

                                      - 15 -

<PAGE>

assignee, transferee, or holder of all or any of the Obligations, shall have
the right to enforce this Guaranty, by suit or otherwise, for the benefit of
such assignee, transferee or holder as fully as if such assignee, transferee
or holder were herein by name specifically given such rights, powers and
benefits.

         14. REMEDIES CUMULATIVE. No delay by the Lenders and the Administrative
Agent, or any of them, in the exercise of any right or remedy shall operate as a
waiver thereof, and no single or partial exercise by the Lenders and the
Administrative Agent, or any of them, of any right or remedy shall preclude
other or further exercise thereof or the exercise of any other right or remedy.
No action by the Lenders and the Administrative Agent, or any of them, permitted
hereunder shall in any way impair or affect this Guaranty. For the purpose of
this Guaranty, the Obligations shall include, without limitation, all
Obligations of the Borrower to the Lenders and the Administrative Agent
notwithstanding any right or power of any third party, individually or in the
name of the Borrower or any other Person, to assert any claim or defense as to
the invalidity or unenforceability of any such Obligation, and no such claim or
defense shall impair or affect the obligations of the Guarantor hereunder.

         15. SUCCESSORS AND ASSIGNS. This Guaranty shall be binding upon the
Guarantor, its successors and assigns and inure to the benefit of the successors
and assigns of the Guarantor, the Lenders and the Administrative Agent. The
Guarantor shall not assign its rights or obligations under this Guaranty without
the consent of all the Lenders and the Administrative Agent, nor shall the
Guarantor amend this Guaranty, without the consent of the Administrative Agent
and the Required Lenders.

         16. MISCELLANEOUS. This is a Guaranty of payment and not of collection.

shall be held and bound to the Lenders and the Administrative Agent directly as
debtor in respect of the payment of the amounts hereby guaranteed. All
reasonable costs and expenses, including, without limitation, attorneys' fees
and expenses, incurred by the Lenders and the Administrative Agent, or any of
them, in obtaining performance of or collecting payments due under this Guaranty
shall be deemed part of the Obligations guaranteed hereby. Any notice or demand
which the Lenders and the Administrative Agent, or any of them, may wish to give
shall be served upon the Guarantor in the fashion prescribed for notices in
Section 11.1 of the Loan Agreement in care of the Borrower at the address for
the Borrower set forth in or otherwise provided pursuant to Section 11.1 of the
Loan Agreement, and the notice so sent shall be deemed to be served as set forth

acknowledges that any financial accommodations by the Lenders and the
Administrative Agent, or any of them, to the Borrower, including, without
limitation, the extension of the Loans, are and will be of direct interest,
benefit and advantage to the Guarantor.

federal court of competent jurisdiction sitting within the area comprising the
Southern District of California on the date of this Guaranty. The Guarantor
hereby agrees, to the extent permitted by Applicable Law that service of the
summons and complaint and all other process which may be served in any such
suit, action or proceeding may be effected by mailing by registered mail a copy
of such process to the offices of the Borrower, as set forth in or otherwise
provided pursuant to Section 11.1 of the Loan Agreement, and that personal

prohibit service of process by any other method permitted by law, or the
bringing of any suit, action or proceeding in any other jurisdiction. The
Guarantor agrees that final judgment in such suit, action or proceeding shall be
conclusive and may be enforced in any other jurisdiction by suit on the judgment
or in any other manner provided by Applicable Law.
