                               GUARANTY AGREEMENT

      THIS GUARANTY AGREEMENT (this "GUARANTY") is made and delivered as of this
31s day of December, 2002, by SPANISH BROADCASTING SYSTEM, INC., a Delaware
corporation ("GUARANTOR") in favor of BIG CITY RADIO, INC., a Delaware
corporation ("BCR") and BIG CITY RADIO-CHI, L.L.C., a Delaware limited liability
company ("BCR-CHI"; BCR together with BCR-CHI, "SELLER").

      WHEREAS, Seller has entered into an Asset Purchase Agreement, dated as of
even date herewith (the "ASSET PURCHASE AGREEMENT") with Spanish Broadcasting
System of Illinois, Inc., a Delaware corporation ("PURCHASER");

      WHEREAS, BCR-CHI has entered into a Time Brokerage Agreement, dated as of
even date herewith (the "TIME BROKERAGE AGREEMENT") with Purchaser, which shall
become effective as of January 6, 2003; and

      WHEREAS, Guarantor is the parent corporation of Purchaser and desires that
Seller execute the Asset Purchase Agreement and that BCR-CHI execute the Time
Brokerage Agreement.

      NOW, THEREFORE, for value received, Guarantor hereby agrees as follows:

      1. Guarantor irrevocably and unconditionally guarantees to Seller the
prompt performance and payment when due of all of Purchaser's obligations under
the Asset Purchase Agreement and the Time Brokerage Agreement (the
"OBLIGATIONS"), including but not limited to the payment of the purchase price
and fee thereunder.

      2. The obligations of Guarantor under this Guaranty shall be absolute,
unconditional and irrevocable, and shall remain in full force and effect until
the Obligations shall have been satisfied in full, it being the express purpose
and intent of Guarantor that its obligations hereunder shall not be discharged
except by payment, performance, discharge or other satisfaction in full of all
of Guarantor's obligations hereunder. Such obligations shall not be in any
manner whatsoever affected, modified or impaired by the happening from time to
time of any assignment of Purchaser's Obligations to a third party or any event
or action that would, in the absence of this clause, result in the release or
discharge of Guarantor, by operation of law or otherwise, from the performance
of observance of any obligation, covenant or agreement contained in this
Guaranty, or the default
<PAGE>
or failure of Guarantor to perform fully any obligations set forth in this
Guaranty.

      3. Guarantor waives diligence, presentment, protest, notice, demand,
dishonor and notice of dishonor and any other defenses available to it hereunder
as a surety and agrees to be bound to the Obligations as fully as if it were a
co-obligor. The parties to the Asset Purchase Agreement and the Time Brokerage
Agreement may enter into any amendment, waiver or modification of the Asset
Purchase Agreement or the Time Brokerage Agreement, as the case may be, whether
or not such amendment, waiver or modification would in any way increase or
decrease the extent of Guarantor's obligations hereunder, without notice to or
consent of Guarantor and without thereby releasing Guarantor hereunder or
incurring any liability to Guarantor.

      4. No failure or delay or lack of demand, notice or diligence in
exercising any right under this Guaranty shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right under this Guaranty.

      5. This Guaranty is an absolute, unconditional and continuing guaranty of
payment and performance and not of collection. Seller need not exhaust or pursue
any remedy or take any action in respect of the default of any obligation
guaranteed hereby prior to or as a condition to proceeding directly under this
Guaranty against Guarantor.

      6. Guarantor represents and warrants to Seller that it has the corporate
power and authority to enter into this Guaranty, that all corporate and
governmental approvals needed by it to enter into and to perform this Guaranty
have been secured or obtained, and that this Guaranty is a legal and valid
obligation binding upon it and is enforceable in accordance with its terms, and
that the execution of this Guaranty does not conflict with any agreement,
undertaking, or instrument to which it is party. The undersigned represents that
he or she is fully authorized to execute and deliver this Guaranty on behalf of
Guarantor.

      7. Guarantor agrees that the obligation of Guarantor as a guarantor shall
not be impaired, modified, changed, released, or limited in any manner
whatsoever by any impairment, modification, change, release, or ]imitation of
the liability of Purchaser or its estate in bankruptcy, resulting from the
operation of any present or future provision of the bankruptcy laws or other
similar statute, or from the decision of any court.

                                        2
<PAGE>
      8. Guarantor agrees that its obligations hereunder are irrevocable, are
joint and several, and are independent of the obligations of Purchaser; that a
separate action or actions may be brought and prosecuted against Guarantor
regardless of whether any action is brought against Purchaser or whether
Purchaser is joined in any such action or actions; and that Guarantor waives the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement hereof.

      9. Guarantor agrees to pay all costs, expenses and fees which may be
incurred by Seller in enforcing this Guaranty or in protecting the rights of
Seller following any default on the part of Guarantor hereunder, whether the
same shall be enforced by suit or otherwise.

      10. This Guaranty is and shall be in every particular available to the
successors and assigns of Seller and is and shall always be fully binding upon
the successors and assigns of Guarantor, provided that Guarantor shall not
assign any of its rights or obligations hereunder without the written consent of
Seller.

      11. This Guaranty shall be governed by and construed in accordance with
the laws of the State of New York as applied to contracts made and performed
within the State of New York, without regard to principles of conflicts of law.
Each of the parties hereto agrees to submit to the jurisdiction of the courts of
the State of New York in any action or proceeding arising out of or relating to
this Guaranty.

         or (ii) the date that is five hundred and forty-seven (547) days
         following the Commercial Launch Date. Such payment shall be made in
         accordance with Section 3.1(d).

                  (c) From and after an Appellate Court Decision Date or, in the
         event that the five hundred and forty-seven (547) day period described
         in Section 3.1(b) has lapsed prior to an Appellate Court Decision Date,
         KUDCO shall pay to each of ANDRX and GENPHARM six and one quarter
         percent (6.25%) of the Net Profit from the KUDCO Product during the
         seven hundred and thirty (730) day period from and after the earlier of
         (i) an Appellate Court Decision Date or (ii) the date that is five
         hundred and forty-seven (547) days following the Commercial Launch
         Date. Such payment shall be made in accordance with Section 3.1(d).

                  (d) Net Profit owing by KUDCO under this Section 3.1 shall be
         payable Monthly (a "MONTHLY INSTALLMENT") by the wire transfer of
         immediately available funds to such account or accounts as are
         designated by ANDRX or GENPHARM, as applicable. A Monthly Installment
         shall be paid within sixty (60) days after the last Business Day of the
         applicable Month; provided, however, that the Monthly Installments in
         respect of the Month in which the first commercial sale of the KUDCO
         Product occurs and the first full Month thereafter shall be paid within
         ninety (90) days after the last Business Day of the applicable Month.
         Each Monthly Installment shall be based upon KUDCO's reasonable
         estimate of the Net Profit earned during the applicable Month, and one

                                      -8-
<PAGE>

         or more subsequent Monthly Installments shall be adjusted, without
         duplication, to account for any discrepancy between the Net Profit
         estimated and those actually earned during such applicable Month.
         Except as stated in this Section 3.1, KUDCO shall have no obligation to
         share Net Profits with ANDRX or GENPHARM under this Agreement. KUDCO
         shall have no obligation to share Net Profits under more than one of
         Sections 3.1(a), 3.1(b) or 3.1(c) with respect to the sale of any
         particular unit of KUDCO Product, it being understood that Net Profits
         may be reclassified from one time period referred to in Section 3.1(a),
         3.1(b) or 3.1(c) (each A "PROFIT SHARE TIME PERIOD") into another or
         from a time period outside the Profit Share Time Periods into one of
         them, in each case as per Section 3.1(e).

                  (e) (*)

                  (f) In the event an Injunction is effective prior to or during
         the Profit Share Time Periods from time to time, KUDCO shall share with
         ANDRX and GENPHARM any Net Damages it receives in respect of such
         Injunction in accordance with the percentages set forth in Section
         3.1(a), 3.1(b) and 3.1(c), as appropriate. Such Net Damages shall be
         paid by the wire transfer of immediately available funds to such
         account or accounts as are designated by ANDRX or GENPHARM, as
         applicable, within ten (10) Business Days following KUDCO's receipt of
         such Net Damages. In the event there are no Net Damages in connection
         with such Injunction, then the Profit Share Time Periods shall be
         deemed tolled for the duration of such Injunction.

         3.2 NEGATIVE NET SALES. In the event that the Net Sales during any
Month are negative, whether due to price reductions, returns, retroactive price
or shelf stock adjustments, price equalizations or otherwise, each of ANDRX and
GENPHARM shall, to the extent it has previously received Net Profit pursuant to
Section 3.1, reimburse KUDCO for ANDRX's or GENPHARM's, as applicable,
proportionate share of such negative Net Sales, such proportionate share to
equal the percentage interest of ANDRX or GENPHARM, as applicable, in Net
Profits in effect, in whole or on average if in part, during such Month.
Reimbursements of negative Net Sales owing by ANDRX or GENPHARM, as applicable,
under this Section 3.2 shall be payable Monthly (a "MONTHLY REIMBURSEMENT") by
the wire transfer of immediately available funds to such account or accounts as
are designated by KUDCO. A Monthly Reimbursement shall be paid within 60 days
after the last Business Day of the applicable Month. Each Monthly Reimbursement
shall be based upon KUDCO's reasonable estimate of the negative Net Sales during
the applicable Month and one or more subsequent Monthly Reimbursements shall be
subsequently adjusted, without duplication, to account for any discrepancy
between the negative Net Sales estimated and those actually suffered during such
applicable Month. KUDCO may offset a Monthly Reimbursement against future
Monthly Installments if such Monthly Reimbursement is not timely paid or the
parties otherwise so agree. This Section 3.2 shall survive any termination of
this Agreement for a period of two (2) years.

         3.3 RECORDS AND AUDIT. KUDCO and its Affiliates shall keep full, true
and accurate books of account containing all particulars that may be necessary

to ANDRX or GENPHARM. Such books of account shall be kept at KUDCO's principal
place of business or the principal place of business of the appropriate
Affiliate of KUDCO to which this Agreement relates. Such books and the
supporting data shall be open, at all reasonable times and upon reasonable
notice during the term of this Agreement and for two (2) years after its
termination, to the inspection of a firm of certified public accountants,
selected by ANDRX and GENPHARM and reasonably acceptable to KUDCO, for the
purpose of verifying KUDCO's Net Profit statements; provided, however, that such
inspection shall not occur more than once per calendar year. All information
learned in connection with, or generated as a result of, any such inspection
shall be treated as KUDCO Proprietary Information for all purposes hereunder
and, prior to commencing any such inspection, the relevant certified public
accountants shall enter into a written agreement, in form and substance
reasonably satisfactory to KUDCO, to be bound by the confidentiality provisions
hereof, as they relate to KUDCO Proprietary Information. Except as otherwise
provided in this Section 3.3, the cost of any such examination shall be paid by
ANDRX or GENPHARM, as applicable. In the event that any such inspection reveals
a deficiency in excess of 5% of a Monthly Installment (as adjusted pursuant to
this Agreement prior to such inspection) covered by the inspection, KUDCO shall
promptly pay ANDRX or GENPHARM, as applicable, the deficiency, plus interest,
and shall reimburse ANDRX or GENPHARM, as applicable, for the reasonable and
documented fees and expenses paid to such accountants in connection with their
inspection of such period.

         3.4 MONTHLY REPORTS. In respect of any Month after the first commercial
sale of the KUDCO Product in which any of Sections 3.1(a), 3.1(b) or 3.1(c) is
in effect, KUDCO shall (i) within ten (10) Business Days of the last Business
Day of such Month, deliver to each of ANDRX and GENPHARM a written report (a
"MONTHLY REPORT") setting forth the estimated Net Sales, Cost of Goods Sold,
Gross Margin, Other Costs and Net Profit in respect of the KUDCO Product for
such Month and (ii) on or before making a Monthly Installment in respect of such
Month, deliver to each of ANDRX and GENPHARM a Monthly Report in respect of the
KUDCO Product for such Month. Such estimates shall be prepared by KUDCO in good
faith.

         3.5 (*)

         3.6 (*)

         3.7 LATE PAYMENTS. Any amounts not paid by KUDCO, ANDRX or GENPHARM
when due under this Agreement shall be subject to interest from and including
the date payment is due through and including the date upon which ANDRX,
GENPHARM or KUDCO, as applicable, has collected immediately available funds in
an account designated by ANDRX, GENPHARM or KUDCO, as applicable, at a rate
equal to the prime rate of interest quoted in the Money Rates section of THE
WALL STREET JOURNAL, calculated daily on the basis of a 365-day year, as
applicable.

                  (i)      any breach of any representation or warranty made by
                           KUDCO in this Agreement or any agreement, instrument
                           or document delivered by KUDCO pursuant to the terms
                           of this Agreement; or

                                      -16-
<PAGE>

                  (ii)     any failure to perform duly and punctually any
                           covenant, agreement or undertaking on the part of
                           KUDCO contained in this Agreement.

                  (c) Notwithstanding anything herein to the contrary, no party
         shall have any right to seek indemnification hereunder or obligation to
         provide indemnification based on any claim for patent infringement or
         any claim asserted by Astra, it being understood that this Section
         7.1(c) shall not affect the calculation of Other Costs.

         7.2 NOTICE AND OPPORTUNITY TO DEFEND. Promptly after receipt by a party
hereto of notice of any claim which could give rise to a right to
indemnification pursuant to Section 7.1. such party (the "INDEMNIFIED PARTY")
shall give the indemnifying party or parties (the "INDEMNIFYING PARTY") written
notice describing the claim in reasonable detail. The failure of an Indemnified
Party to give notice in the manner provided herein shall not relieve the
Indemnifying Party of its obligations under this Section, except to the extent
that (i) such failure to give notice materially prejudices the Indemnifying
Party's ability to defend such claim or (ii) such notice is not given prior to
thirty (30) months following any termination of this Agreement, or, if such
notice relates to any obligation that survives the termination of this
Agreement, prior to the first anniversary of the termination of such obligation.
The Indemnifying Party shall have the right, at its option, to compromise or
defend, at its own expense and by its own counsel, any such matter involving the
asserted liability of the party seeking such indemnification. If the
Indemnifying Party shall undertake to compromise or defend any such asserted
liability, it shall promptly (and in any event not less than ten (10) days after
receipt of the Indemnified Party's original notice) notify the Indemnified Party
in writing of its intention to do so, and the Indemnified Party agrees to
cooperate fully with the Indemnifying Party and its counsel in the compromise or
defense against any such asserted liability. All reasonable costs and expenses
incurred in connection with such cooperation shall be borne by the Indemnifying
Party. If the Indemnifying Party elects not to compromise or defend the asserted
liability, fails to notify the Indemnified Party of its election to compromise
or defend as herein provided, fails to admit its obligation to indemnify under
this Agreement with respect to the claim, or, if in the reasonable opinion of
the Indemnified Party, the claim could result in the Indemnified Party becoming
subject to injunctive relief or relief that could materially adversely affect
the ongoing business of the Indemnified Party in any manner, the Indemnified
Party shall have the right, at its option, to pay, compromise or defend such
asserted liability by its own counsel and its reasonable costs and expenses
shall be included as part of the indemnification obligation of the Indemnifying
Party hereunder. Notwithstanding the foregoing, neither the Indemnifying Party
nor the Indemnified Party may settle or compromise any claim over the objection
of the other; provided, however, that consent to settlement or compromise shall
not be unreasonably withheld. In any event, the Indemnified Party and the
Indemnifying Party may participate, at their own expense, in the defense of such
asserted liability. If the Indemnifying Party chooses to defend any claim, the
Indemnified Party shall make available to the Indemnifying Party any books,
records or other documents within its control that are necessary or appropriate
for such defense. Notwithstanding anything to the contrary in this Section 7.2,
(i) the party conducting the defense of a claim shall (A) keep each of the other
parties informed on a reasonable and timely basis as to the status of the
defense of such claim (but only to the extent such other party is not
participating jointly in the defense of such claim), and (B) conduct the defense
of such claim in a prudent manner, and (ii) the Indemnifying Party shall not
cease to defend, settle or otherwise dispose of any claim

                                      -17-
<PAGE>

without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld).

         7.3 INDEMNIFICATION PAYMENT OBLIGATION. Excluding amounts payable to
ANDRX or GENPHARM under Section 3.1 or amounts payable to KUDCO under Section
3.2 or Section 3.6, no Indemnifying Party will have any obligations under
Sections 7.1(a) or 7.1(b) until the cumulative aggregate amount of Damages
incurred or suffered by the Indemnified Party which the Indemnifying Party is
otherwise subject to under this Agreement exceeds Five Hundred Thousand Dollars
($500,000) at which time the entire cumulative aggregate amount of such Damages
shall be covered. The provisions of this Section 7.3 shall not limit or
otherwise affect the obligations of any Indemnifying Party under any other
Section of this Agreement.

         7.4 INDEMNIFICATION PAYMENT ADJUSTMENTS. The amount of any Damages for
which indemnification is provided under this Section 7 shall be reduced to take
account of any net tax benefit and shall be increased to take account of any net
tax detriment actually arising from the incurrence or payment of any such
Damages or from the receipt of any such indemnification payment and shall be
reduced by the insurance proceeds actually received and any other amount
actually recovered, if any, by the Indemnified Party with respect to any
Damages. If any Indemnified Party shall have received any payment pursuant to
this Section 7 with respect to any Damages and shall subsequently have received
insurance proceeds or other amounts with respect to such Damages, then such
Indemnified Party shall pay to the Indemnifying Party an amount equal to the
difference (if any) between (i) the sum of the amount of those insurance
proceeds or other amounts received and the amount of the payment by such
Indemnifying Party pursuant to this Section 7 with respect to such Damages and
(ii) the amount necessary to fully and completely indemnify and hold harmless
such Indemnified Party from and against such Damages; provided, however, in no
event will such Indemnified Party have any obligation pursuant to this sentence
to pay to such Indemnifying Party an amount greater than the amount of the
payment by such Indemnifying Party pursuant to this Section 7 with respect to
such Damages.

         7.5 INDEMNIFICATION PAYMENT. Upon the final determination of liability
and the amount of the indemnification payment under this Section 7, the
appropriate party shall pay to the applicable party, as the case may be, within
ten (10) business days after such determination, the amount of any claim for
indemnification made hereunder by the wire transfer of immediately available
funds to such account or accounts as are designated by such other party.

         7.6 SURVIVAL. Subject to the notice periods described in Section 7.2,
the provisions of Section 7 shall survive any termination of this Agreement.
Each Indemnified Party's rights under Section 7 shall not be deemed to have been
waived or otherwise affected by such Indemnified Party's waiver of the breach of
any representation, warranty, agreement or covenant contained in or made
pursuant to this Agreement, unless such waiver expressly and in writing also
waives any or all of the Indemnified Party's right under Section 7.

         7.7 CONSEQUENTIAL DAMAGES. Notwithstanding anything to the contrary in
this Agreement, neither ANDRX, GENPHARM nor KUDCO shall be liable to the other
by reason of any representation or warranty, covenant or other term hereunder or
any duty of common law for any special, consequential, incidental or punitive
loss or damage, including lost profits, whether

                                      -18-
<PAGE>

occasioned by the negligence of the respective parties, their employees or
agents or otherwise, it being understood that the foregoing shall not limit
KUDCO's payment obligations pursuant to Section 3.1.

         7.8 EXCLUSIVE REMEDY. ANDRX, GENPHARM and KUDCO each acknowledge and
agree that, except for any injunctive relief if such remedy is appropriate under
the circumstances, the foregoing indemnification provisions of this Section 7
shall be the exclusive remedy of ANDRX, GENPHARM or KUDCO with respect to the
transactions contemplated by this Agreement. Notwithstanding the foregoing, the
parties acknowledge that claims under Section 3.1(e) may be made in accordance
with this Section 7.

                                    SECTION 8

                                   TERMINATION

         8.1 TERMINATION. The term of this Agreement shall begin upon the date
hereof and, unless sooner terminated as hereinafter provided, shall end upon the
earlier of (i) October 20, 2007 or (ii) subject to Section 3.1(f), the date that
is one thousand two hundred and seventy-seven (1,277) days following the
Commercial Launch Date (the "EXPIRATION DATE"). Notwithstanding the foregoing,
this Agreement may be terminated prior to the Expiration Date as follows:

                  (a) [Intentionally Omitted]

                  (b) TERMINATION FOR DEFAULT. ANDRX, GENPHARM and KUDCO each
         shall have the right to terminate this Agreement for default upon the
         other's material failure to comply with the terms and conditions of
         this Agreement. At least thirty (30) days prior to any such termination
         for default, the party seeking to so terminate shall give the other
         written notice of its intention to terminate this Agreement in
         accordance with the provisions of this Section 8.1(b), which notice
         shall set forth the default(s) which form the basis for such
         termination. If the defaulting party fails to correct such default(s)
         within thirty (30) days after receipt of notification, or if the same
         cannot reasonably be corrected or remedied within thirty (30) days,
         then if the defaulting party has not commenced curing said default(s)
         within said thirty (30) days and be diligently pursuing completion of
         same, then such party immediately may by written notice terminate this
         Agreement with immediate effect.

                  (c) AUTOMATIC TERMINATION. This Agreement shall automatically
         terminate in its entirety with immediate effect on the date that the
         ANDRX Product or the GENPHARM Product may be lawfully and prudently
         marketed in the Territory without risk of patent infringement.

                  (d) OTHER TERMINATION. Each of (i) ANDRX and GENPHARM or (ii)
         KUDCO may by written notice terminate this Agreement in its entirety
         with immediate effect in the event that (A) KUDCO has not received
         final marketing approval from the FDA on or prior to March 31, 2003 or
         (B) KUDCO is permanently enjoined from selling

                                      -19-
<PAGE>

         the KUDCO Product prior to April 20, 2007 and (x) no appeal is taken or
         (y) said permanent injunction is affirmed on appeal, in each case such
         that KUDCO is not performing and shall not in the future perform any
         Activities with respect to the KUDCO Product prior to April 20, 2007.

         8.2 CONTINUING OBLIGATIONS. Termination of this Agreement for any
reason shall not relieve the parties of any obligation accruing prior thereto or
any ongoing obligations hereunder including Section 3.1, and shall be without
prejudice to the rights and remedies of either party with respect to any
antecedent breach of the provisions of this Agreement. This Section 8.1 shall be
the exclusive means of termination hereof and shall not be in lieu of any other
remedies available under this Agreement to a party hereto for any default
hereunder on the part of each of the other parties. Without limiting the
generality of the foregoing, no termination of this Agreement, whether by lapse
of time or otherwise, shall serve to terminate the obligations of the parties
hereto under Sections 3.2, 3.3, 3.6, 6.3, 6.4, 6.6, 7, 8.2 and 9, and such
obligations shall survive any such termination in accordance with their
respective terms.

                                    SECTION 9

                                  MISCELLANEOUS

         9.1 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
and permitted assigns; provided, however, that neither ANDRX, GENPHARM nor KUDCO
may assign any of its rights, duties or obligations hereunder without the prior
written consent of each of the other parties hereto, which consent may not be
unreasonably withheld or delayed. Notwithstanding the foregoing, no prior
written consent shall be required for an assignment from time to time of this
Agreement (i) in connection with the acquisition by a Third Party of
substantially all of the assets or outstanding shares of, or merger with, ANDRX,
GENPHARM or KUDCO, as the case may be, if such Person caused such successor or
assignee to expressly assume its obligations hereunder pursuant to a signed

parties hereto, (ii) in connection with the acquisition by a Third Party of
substantially all of the assets relating to this Agreement of ANDRX, GENPHARM or

substance reasonably satisfactory to each of the other parties hereto or (iii)
from ANDRX or KUDCO, as applicable, to such Person's Affiliates, provided that
no such assignment to such Person's Affiliates shall relieve the assignee of its
duties or obligations hereunder.

Commercial Rules of Arbitration then in effect of the American Arbitration
Association except as set forth herein or as agreed in writing by the parties.
The parties agree that in connection with any such arbitration each party (i)
may seek provisional relief and (ii) shall take all steps necessary to have in a
United States location funds sufficient to pay the amount demanded by the other
party, it being understood that such funds need not be made available until the
time of the arbitral award and that this provision is specifically enforceable .
Said provisional relief shall be available from the panel or from a court of
competent jurisdiction, which the parties stipulate may be a state or federal
court in New York for these purposes. Any award rendered shall be final and
conclusive upon the parties and a judgment thereon may be entered in a court
having competent jurisdiction and may include an award of reasonable attorney's
fees to the substantially prevailing party, as such arbitral tribunal deems
appropriate, including with respect to claims made under Section 3.1(e). Any
arbitration hereunder shall be (i) submitted to an arbitration tribunal

rules then in effect under the Federal Rules of Civil Procedure for a period not
to exceed 90 days; and (iii) require the award to be accompanied by findings of
fact and a statement of reasons for the decision. Except where clearly prevented
by the area in dispute, both parties agree to continue performing their
respective obligations under this Agreement while the dispute is being resolved.

such remedy is an appropriate form of remedy under the circumstances.
