                             JOINT VENTURE AGREEMENT

         This Agreement (this "Agreement") is entered into this 4th day of
February, 1999, by and between Telefonica Larga Distancia de Puerto Rico, Inc.,
a corporation organized under the laws of the Commonwealth of Puerto Rico,
herein represented by its General Manager, Jose Luis Fernandez, of legal age,
married, executive and resident of Rio Piedras, Puerto Rico (hereinafter,
"TLD"), and ClearComm, L.P., a limited partnership organized under the laws of
Delaware, herein represented by Javier O. Lamoso, of legal age, married,
executive and resident of Rio Piedras, Puerto Rico (hereinafter, "CC"), in its
capacity as President of CC's general partner SuperTel Communications Corp.
("SuperTel").

                                   WITNESSETH
         WHEREAS, CC is the licensee of the personal communications service
("PCS") licenses for the 1902.5-1910.0 and 1982.5-1990.0 MHZ bands for the San

Basic Trading Areas (collectively, the "Licenses") and of certain radio
frequency plans, transmission plans, business plans, preliminary engineering
design work, and other studies, plans or reports relevant to the operation a PCS
network in Puerto Rico (the "Other Assets");

         WHEREAS, TLD is a licensed telecommunications carrier engaged in 
business in Puerto Rico;

         WHEREAS, CC and TLD are interested in jointly developing a 1900 MHZ
band PCS network in Puerto Rico (the "Network");

         NOW THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the sufficiency of which is hereby
acknowledged, and relying on each party's respective covenants, representations
and warranties, the parties agree as follows:

                            ARTICLE I. JOINT VENTURE

         Section 1.01 Articles of Incorporation. CC has organized a corporation
under the Puerto Rico General Corporation Laws to develop and operate the
Network. The name of the corporation will be NewComm Wireless Services, Inc.
("NewComm"). The articles of incorporation of NewComm are attached as Exhibit A
hereof.

         Section 1.02 The By-Laws. At the Closing Date, CC will cause the
adoption by NewComm of by-laws substantially in the form of Exhibit B hereof.

         Section 1.03 CC's Capital Contribution. At the Closing Date, CC will
transfer all of its rights, title and interest to the Licenses and the Other
Assets to NewComm and NewComm will assume CC's debt with the Federal
Communications Commission ("FCC") (the "CC Debt") pursuant to an Assumption
Agreement in the form required by the FCC (the Licences and the Other Assets,
net of the CC Debt, the "CC Contribution"). In exchange for the CC Contribution,
NewComm will issue to CC 750 shares of its Class A Common Stock, par value one
cent ($0 .01) per share, constituting all of NewComm's issued and outstanding
shares of stock.

         Section 1.04 TLD's Contribution. Concurrently with the CC Contribution,
TLD will transfer NINETEEN MILLION NINE HUNDRED SIXTY THOUSAND DOLLARS
($19,960,000.00) to NewComm in exchange for NewComm's Secured Convertible
Promissory


<PAGE>


                                      - 3 -


Note, substantially in the form of Exhibit C hereof (the "Secured Convertible
Promissory Note"). In consideration of TLD's contribution, NewComm will also
execute and deliver a Security Agreement, substantially in the form Exhibit D
hereof and any other documents reasonably required to constitute, subject to the
CC Debt, a valid and enforceable preferential lien upon all of the tangible and
intangible assets and contractual rights of NewComm, including without
limitation the Licenses. In addition, CC will issue a Guarantee and a Pledge
Agreement, substantially in the form of Exhibits E and F hereof.

         Section 1.05 Additional Contributions.

         (a) CC and TLD shall cause NewComm to use its best efforts to secure
financing for the development and construction of the Network . The financing
shall be procured from sources available in the market, under such terms and
conditions as TLD may be able to obtain in its capacity as Manager under the
Management Agreement. In the event that, notwithstanding NewComm's best efforts,
the required financing is not obtained, CC and TLD shall have the option,
subject to any required FCC approval, to contribute the necessary funds to
NewComm, in the same proportion as their respective ownership of NewComm's
common stock (including the common stock into which the Secured Convertible
Promissory Note will be converted)(the "Additional Contribution") in exchange
for (i) NewComm's Class A or Class B Common Stock, par value one cent ($0.01)
per share, in an amount equal to the amount resulting from dividing the amount
of funds contributed by CC or TLD by the market value of each share of NewComm's
common stock agreed to by the parties (or if the parties are unable to agree on
such market value, determined as provided under Section 5.02 of this Agreement)
or (ii) a Promissory Note, substantially in the form of Exhibit G hereof, in


<PAGE>


                                      - 4 -


a principal amount equal to the funds contributed (the "Promissory Note"), at
the option of CC and TLD, respectively; provided that, if any of the parties
does not exercise its option to contribute its share of the Additional
Contribution, the other party may elect to contribute all or a portion of such
party's share.

         (b) Notwithstanding anything to the contrary provided in Sections
1.05(a), neither TLD nor CC shall make an Additional Contribution without the
consent of the other party (the "Diluted Party") to the extent that such
Additional Contribution results (or may result upon the conversion of the
Promissory Note) in reducing the percentage of NewComm's common stock held by
the Diluted Party to less than 40% of NewComm's issued and outstanding shares of
common stock taking into account the number of shares of NewComm common stock
issued in exchange for the Additional Contributions and/or the number of NewComm
shares into which the Promissory Note can be converted. The Diluted Party shall
not withhold its consent if it is demonstrated to the reasonable satisfaction of
the Diluted Party that the Additional Contribution is required to enable NewComm
to develop and operate the Network without materially adversely affecting
NewComm's financial condition, and that NewComm has been unable to secure
additional financing in place of the Additional Contribution.

         (c) In the event that NewComm has the obligation to redeem the CC Debt
prior to its maturity, CC (and TLD, if at the time TLD is a shareholder of
NewComm) shall cause NewComm to borrow funds to redeem the CC Debt. In the event
that NewComm does not have the financial capacity to borrow such funds, or if
any such borrowing would materially adversely affect the financial condition of
NewComm, TLD and CC shall have the option, subject to any required FCC


<PAGE>


                                      - 5 -


approval, to make an Additional Contribution to NewComm, in exchange for
NewComm's common stock or a Promissory Note, at the election of TLD and CC,
respectively, as provided in Section 1.05(a).

         (d) In the event that the financing necessary to develop and construct
the Network is not secured and neither CC nor TLD exercises its option to make
an Additional Contribution to NewComm as provided in this Section 1.05, either
party may terminate this Agreement by giving written notice to the other party
and CC and TLD will dissolve NewComm. Upon such dissolution (i) CC shall receive
the Licenses and the Other Assets and shall assume the CC Debt; (ii) TLD shall
receive all remaining assets of NewComm or, at its option, shall receive the
cash and other liquid assets, other tangible assets selected by TLD (the
"Tangible Assets") and the proceeds from the assets sold by NewComm at TLD's
request, net of the unpaid purchase price of such assets, (the "Sold Assets");
(iii) TLD shall assume NewComm's liabilities consisting of the unpaid purchase
price of the Tangible Assets, (iv) CC shall reimburse TLD all principal and
interest payments made by NewComm on the CC Debt, (v) each of CC and TLD shall
be responsible for one half of all outstanding liabilities, other than
liabilities consisting of the unpaid purchase price of Tangible Assets and the
CC Debt, (vi) CC shall reimburse TLD an amount equal to one half of the amount
resulting after subtracting (A) the disbursements made to acquire the Tangible
Assets, (B) the proceeds from the sale of the Sold Assets, and (C) all principal
and interest payments made by NewComm on the CC Debt, from NewComm's
disbursements, and (vii) CC and TLD shall divide the retained earnings, if any,
of NewComm in proportion to their respective holdings of the common stock of
NewComm.

                                      - 6 -


         Section 1.06 Management Contract and Technology Transfer Agreement. On
the Closing Date, CC shall cause NewComm to execute a Management Agreement with
TLD and a Technology Transfer Agreement with Telefonica Internacional, S.A.
substantially in the form of Exhibits H and I hereof (respectively, the
"Management Agreement" and the "Technology Transfer Agreement").

         Section 1.07 The Closing. The closing of the transactions contemplated
hereunder shall take place at the offices of Axtmayer, Adsuar, Muniz & Goyco,
P.S.C., Hato Rey Towers, Suite 1400, Hato Rey, Puerto Rico, as soon as possible,
but in no event later than thirty (30) business days, after satisfaction or
waiver of the conditions set forth in Article X, or at such other time or place,
as CC and TLD may agree (the date of the closing, the "Closing Date").

                           ARTICLE II. STOCK TRANSFERS

         Section 2.01 Restrictions on Transfers and Issuance of Stock.

         (a) Neither CC nor TLD (upon becoming a shareholder of NewComm) will
Transfer (directly, indirectly or in bankruptcy) its NewComm stock (including
any interest in such stock and any contractual rights that may entitle the
holder to acquire any such stock or an interest therein), whether by operation
of law or otherwise, prior to the Restriction Expiration Date (as defined in
Section 2.02 of this Agreement). As used in this Agreement, the term "Transfer"
shall include any sale, pledge, gift, assignment or other disposition of or
encumbrance of NewComm's stock.

         (b) Except pursuant to the conversion of the Secured Convertible
Promissory Note, the Promissory Note or the Class B Common Stock, or as
otherwise permitted under this Agreement,



<PAGE>


                                      - 7 -



CC and TLD (upon becoming a shareholder of NewComm) will cause NewComm not to
issue any of its shares of common stock (directly, indirectly or in bankruptcy),
including any interest in any such shares or any contractual rights that may
entitle the holder to acquire any such shares of stock or any interest therein,
whether by operation of law or otherwise. 

         (c) In the event that any of the restrictions imposed in Sections
2.01(a) or 2.01(b) upon CC, TLD (upon becoming a shareholder of NewComm) or
NewComm may not be enforced, for any reason whatsoever, the Optionee (as defined
in Section 2.02 of this Agreement) shall have with respect to any Transfer by CC
or TLD, and any issuance by NewComm, of NewComm's stock prohibited by Section
2.01(a) or Section 2.01(b) the right of first refusal set forth in Section 2.02
of this Agreement. In any such event, if at the time of such Transfer the
Optionee is precluded from acquiring the NewComm stock because of (i) the
restrictions upon the transfer of control of the Licenses from SuperTel to
NewComm or the foreign ownership of the Licenses, imposed under the
Communications Act of 1934, as amended, or orders or regulations promulgated
thereunder, or (ii) the designated entity rules set out at 47 CFR 24.709, or any
successor provisions, the Optionee will be entitled to assign such right of
first refusal, in whole or in part, to any person. If the Optionee fails to
exercise the Option (as defined in Section 2.02(b) of this Agreement) the
transferee shall be subject to the obligations of a Third Party under Section
2.02(e) of this Agreement.

         Section 2.02 Right of First Refusal and Right to Join in Sale. After
the ownership restrictions on the Licenses under the FCC designated entity rules
set out at 47 CFR Section 24.709, or any successor provisions, expire (the
"Restrictions Expiration Date"), CC or TLD (upon becoming a shareholder of
NewComm) (the "Transferring Shareholder") may Transfer any of its NewComm

                                      - 8 -




stock to any third party if it receives a bona fide offer (the "Offer") from a
reputable, financially responsible person ("Third Party") which is acceptable to
it, and not less than thirty (30) days prior to the closing date of the proposed
sale, gives written notice thereof (the "Notice of Transfer") to the other party
(the "Optionee") subject to the provisions of this Section 2.02:

         (a) The Notice of Sale shall state that a bona fide offer has been
received and shall contain all the terms and conditions of the Offer and a copy
of all supporting documents.

         (b) The Optionee shall have the option (the "Option") for a period of
fifteen (15) days (the "Option Period ") after receipt of the Notice of Sale to
(i) if the Transfer is of all of the Transferring Shareholder's NewComm stock,
commit to purchase all, but not less than all, of the NewComm stock of the
Transferring Shareholder on the same terms and conditions as set forth in the
Offer, or (ii) if the Transfer is a sale or exchange of less than all of the
Transferring Shareholder's NewComm stock, elect to join in the sale or exchange;
in each case by delivering written notice of its election to the Transferring
Shareholder within the thirty (30) day period.

         (c) If the Optionee elects to purchase the NewComm stock, the closing
of the purchase shall take place on the date designated as the closing date of
the Offer, but in no event later than fifteen (15) days after the expiration of
the Option Period, in the offices of NewComm, or at such other time and place as
may be mutually agreed upon in writing by the Transferring Shareholder and the
Optionee.

         (d) If the Optionee elects to join in the sale or exchange, it will be
entitled to sell or exchange, pursuant to the terms of the Offer, a number of
shares of its NewComm common stock determined by multiplying the Applicable
Percentage times the number of shares of NewComm's 


<PAGE>


                                      - 9 -




common stock held by the Optionee. In such event, the Transferring Shareholder
shall use commercially reasonable efforts to obtain the agreement of the Third
Party to the participation of the Optionee in the sale or exchange, but if no
such agreement is obtained the Transferring Shareholder shall not transfer any
of such Transferring Shareholder's shares to the Third Party. For purposes of
this Section 2.02(d), the Applicable Percentage means a percentage determined by
dividing the number of shares of NewComm's common stock that the Transferring
Shareholder proposes to transfer by the number of NewComm's common stock held by
the Transferring Shareholder (including the number of shares of NewComm's common
stock into which any NewComm security held by the Transferring Shareholder may
be converted).

         (e) In the event the Optionee (i) fails to exercise the Option within
the Option Period, or, (ii) after electing to purchase the Transferring
Shareholder's stock, fails to close the purchase hereunder (unless such failure
to close is attributable to the action or inaction of the Transferring
Shareholder), the Transferring Shareholder shall have the right to Transfer the
NewComm stock to the Third Party designated in the Notice of Transfer in
accordance with the terms of the Offer. However, as a condition to the
effectiveness of such transfer, the Third Party shall thereupon become a party
to this Agreement with the same rights and obligations of the Transferring
Shareholder and, shall confirm such fact by executing a counterpart of this
Agreement.

         (f) The provisions of this Section 2.02 shall not be applicable to a
Transfer to a Permitted Transferee (as defined in Sections 2.04 of this
Agreement) or to a Qualified Public Offering (as defined in Section 2.04(a)(ii)
of this Agreement.

         Section 2.03 Prohibited Transfers. Notwithstanding anything to the
contrary provided in this Agreement, neither CC nor TLD (upon becoming a
shareholder of NewComm) will Transfer any of its shares of NewComm's stock, to
any person (other than CC or TLD) (i) that competes directly or indirectly with
NewComm in the "Business", or (ii) if such person's ownership of shares of

Agreement).

         Section 2.04 Certain Transfers Not Prohibited.

         (a) The restrictions on Transfers of NewComm's stock contained in

1933, as amended (the "Securities Act") ("Permitted Transfers");

         (b) Any and all shares of NewComm's stock in the hands of any

                               ARTICLE V. BUY-OUT

         Section 5.01 TLD Buy-Out.

         (a) For the period between one year in advance of the Restriction
Expiration Date and the Restriction Expiration Date, CC shall have the option to
purchase the Secured Convertible Promissory Note or the NewComm common stock
into which the Secured Convertible Promissory 


<PAGE>


                                     - 15 -




Note is convertible, as applicable, for a purchase price equal to the higher of
(i) one hundred fifty percent (150%) of the sum of the principal and accrued
interest of the Secured Convertible Promissory Note and (ii) one hundred twenty
five-percent (125%) of the market value, at the time of purchase, of the NewComm
stock into which the Secured Convertible Promissory Note and the Interest Note
(as defined in the Secured Convertible Promissory Note) are convertible (the "CC
Option"). The CC Option shall be exercised by delivery of written notice to TLD
of exercise (an "Option Notice") prior to the Restriction Expiration Date. If
the parties are unable to agree on such market value within thirty (30) days of
the Option Notice, CC shall notify to TLD the names of three (3) reputable
internationally recognized investment banking firms ("Bank"). TLD shall within
ten (10) days of receipt of the names, select one Bank who shall determine the
fair market value of such NewComm stock. In the event that TLD fails to select
the Bank within the ten (10) day period, CC shall select the Bank that will
determine the fair market value of such NewComm stock. The determination of the
Bank shall be conclusive and the parties agree not to challenge such
determination value in court proceedings or otherwise. All fees of the Bank
shall be paid by NewComm.


<PAGE>


                                     - 16 -


         (b) The closing of a purchase pursuant to this Section 5.01, shall be
held at a mutually acceptable place and on a mutually acceptable date not sooner
than ten (10) days after receipt of the valuation from the Bank. At such closing
TLD's debt or equity interests in NewComm, as applicable, shall be transferred
free and clear of all pledges, liens, security interest or encumbrances of any
nature whatsoever. The parties shall execute all other documents that may be
reasonably necessary or advisable to effectuate the transactions contemplated
hereby, and CC shall pay the purchase price of the TLD debt or equity interest,
as applicable, in cash, by a cashier's check or by wire transfer.

         (c) If CC exercises the CC Option,

                  (i) the option provided in Section 5.02 of this Agreement 
shall be without further effect;

                  (ii) any and all guarantees issued by TLD or any of its
Affiliates on any outstanding debt of NewComm shall cease to be effective; and

                  (iii) each of TLD and Telefonica Internacional, S.A. will have
the option to terminate the Management Agreement and the Technology Transfer
Agreement, respectively, within thirty (30) days of closing of the purchase
pursuant to this Section 5.01.

         Section 5.02 CC Buy-Out Event.

         (a) At any time after the Restriction Expiration Date, TLD shall have
the option, exercisable at its sole discretion and subject only to any
applicable requirements of the Communications Act of 1934, as amended, or orders
or regulations promulgated thereunder, and/or the Hart-Scott-Rodino Antitrust
Improvement Act of 1976 and its implementing regulations,


<PAGE>


                                     - 17 -


to elect to purchase any of the shares of Class A Common Stock held by CC in the
amount required for TLD to acquire 50.1% of the issued and outstanding common
stock of NewComm (the "Call"). Any such purchase shall be at a price per share
equal to the market value at the time of purchase of a share of NewComm's Class
A Common Stock. The Call shall be exercised by delivery of an Option Notice to
CC. If the parties are unable to agree on such market value within thirty (30)
days of the Option Notice, TLD shall notify to CC the names of three (3)
reputable internationally recognized investment banking firms ("Bank"). CC shall
within ten (10) days of receipt of the names, select one Bank who shall
determine the fair market value of a share of NewComm's Class A Common Stock. In
the event that CC fails to select a Bank within the ten (10) day period, TLD
shall select the Bank that will determine the fair market value of a share of
NewComm's Class A Common Stock. The determination of the Bank shall be
conclusive and the parties agree not to challenge such determination value in
court proceedings or otherwise. All fees of the Bank shall be paid by NewComm.

         (b) The closing of a purchase pursuant to this Section 5.02, shall be
held at a mutually acceptable place and on a mutually acceptable date not sooner
than ten (10) days after receipt of the valuation from the Bank. At such closing
the shares of NewComm's Class A Common Stock shall be transferred free and clear
of all pledges, liens, security interests or encumbrances of any nature
whatsoever. The parties shall execute all other documents that may be reasonably
necessary or advisable to effectuate the transactions contemplated hereby, and
TLD shall pay the purchase price of the Class A Common Stock in cash, by a
cashier's check or by wire transfer.

                         ARTICLE VI. REGISTRATION RIGHTS

         Section 6.01 Required Registration.

         (a) At any time on or after the Restriction Expiration Date, if CC
proposes to dispose of at least the Minimum Number (as defined below) of its
NewComm shares of stock (the "CC Shares") in a registered offering, it may
request NewComm in writing to effect the registration of such CC Shares, stating
the number of CC Shares to be disposed of and the intended method of disposition
of such CC Shares. NewComm will use all commercially reasonable efforts to
effect promptly the registration under the United States Securities Act of 1933,
as amended (the "Act") of all CC Shares specified in CC's request. The managing
underwriters that will place the CC Shares shall be those mutually acceptable to
CC and TLD.

         (b) If TLD determines, in response to a request for registration of CC
Shares that the filing of a registration statement under the Act would not be in
the best interests of NewComm, NewComm may delay acting upon such request for a
period (not to exceed one hundred eighty (180) days from its receipt of such
request) that TLD deems reasonable so as to be in the best interests of NewComm.

         (c) The "Minimum Number" shall mean all of the issued and outstanding
shares of NewComm common stock held by CC; provided that such shares have an
aggregate estimated disposition price (before deduction of underwriting
discounts and expenses of sales) of at least Forty Million Dollars
($40,000,000.00) million (but in no event in an initial public offering less
than an amount to create a viable public trading market).


<PAGE>


                                     - 19 -


         (d) NewComm shall not be required to effect more than one registration
pursuant to this Section 6.01. For purposes of the foregoing sentence, in the
event that NewComm shall have filed a registration statement upon the request of
CC, and thereafter such request shall have been withdrawn by CC other than after
a delay caused by NewComm pursuant to Section 6.01(b), such withdrawn
registration shall be considered to be a registration.

         (e) NewComm shall not be required to cause a registration statement
requested hereunder to become effective prior to one hundred eighty (180) days
following the effective date of the most recent registration by NewComm of
equity or equity-linked securities under the Act (other than a registration
effected solely to implement an employee benefit plan or a transaction to which
Rule 145 of the Securities and Exchange Commission (the "SEC") is applicable);
provided, however, that NewComm shall use all commercially reasonable efforts to
achieve such effectiveness promptly following such one hundred eighty (180) day
period if CC's request has been made prior to the expiration of such one hundred
eighty (180) day period.

         (f) Notwithstanding anything to the contrary herein provided, upon the
exercise by CC of its registration rights pursuant to this Section 6.01, TLD
shall have the option of transferring TLD shares of common stock to CC in
exchange for the CC Shares and effect the registration of such TLD shares, as
provided hereunder, in lieu of the registration of the CC Shares; provided that
a nationally recognized investment banking firm selected by CC from a list of
three (3) such investment banking firms prepared by TLD determines that it would
be in the best interest of CC to offer the shares of TLD instead of the CC
Shares. In such event, the TLD shares of common stock to be issued in exchange
for the CC Shares shall have a market value equal to the market


<PAGE>


                                     - 20 -


value of the CC Shares, as determined by the investment banking firm selected by
CC. The fees, costs and expenses of the investment banking firm shall be paid by
TLD.
         (g) CC shall bear and pay all expenses incurred in connection with the
registration, filing or qualification of CC Shares pursuant to this Section
6.01, including (without limitation) all registration, filing and qualification
fees, printing and accounting fees relating or apportionable thereto, the fees
and disbursements of counsel, underwriting discounts and commissions, and TLD,
in its capacity as Manager under the Management Contract will participate at the
expense of NewComm in the presentations made by NewComm to promote the sale of
the CC Shares.

         Section 6.02 Piggy-Back Registration.

         (a) If at any time after the Restriction Expiration Date NewComm
determines to register any of its shares of common stock under the Act in
connection with the public offering of such securities by NewComm solely for
cash (other than a registration relating solely to the sale of securities to
participants in a NewComm employee benefit plan or a transaction to which Rule
145 of the SEC applies, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of NewComm stock other than information
on selling shareholders), NewComm shall, at such time, promptly give CC written
notice of its intention to effect such registration. Upon the written request of
CC given within twenty (20) days after mailing of such notice by NewComm,
NewComm shall use commercially reasonable efforts to cause to be registered
under the Act all of the shares that CC has requested to be registered (the
"Piggy-Back Shares") (a "Piggy-Back


<PAGE>


                                     - 21 -


Registration"); provided that NewComm shall have the right to postpone or
withdraw any such registration effected pursuant to this subsection without
obligation to CC.

         (b) It shall be a condition precedent to NewComm's obligation to take
any action pursuant to this Section with respect to the Piggy-Back Shares that
CC shall furnish to NewComm such information regarding itself, the NewComm stock
held by it, and the intended method of disposition of such securities as shall
be required to effect the registration of such shares.

         (c) NewComm shall bear and pay all expenses incurred in connection with
the registration, filing or qualification of the Piggy-Back Shares with respect
to CC's Piggy-Back Registrations, including (without limitation) all
registration, filing and qualification fees, printing and accounting fees
relating or apportionable thereto, and the fees and disbursements of one counsel
for CC (provided it shall be counsel to NewComm), but excluding underwriting
discounts and commissions relating to Piggy-Back Shares which shall be paid by
CC.
         (d) In connection with any offering involving an underwriting of
NewComm's stock, NewComm shall not be required to include any Piggy-Back Shares
in such underwriting unless CC accepts the terms of the underwriting as agreed
upon between NewComm and the underwriters, and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success
of the offering by NewComm. If the total amount of Piggy-Back Shares to be
included in such offering exceeds the amount of shares sold other than by
NewComm that the underwriters determine in their sole discretion is compatible
with the success of the offering, then NewComm shall be required to include in
the offering only that number of PiggyBack Shares which the underwriters
determine in their sole discretion will not jeopardize the success of the
offering.

         (e) CC shall not have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Agreement.

         (f) In the event any Piggy-Back Shares are included in a registration
statement under this Agreement:

                  (i) To the extent permitted by law, NewComm will indemnify and
hold harmless CC and its officers and directors, any underwriter (as defined in
the Act) for CC and each person, if any, who controls CC or the underwriter
within the meaning of the Act or the Securities Exchange Act of 1934 (the "1934
Act") (each, for purposes of this Section 6.02, an "Indemnitee"), against any
losses, claims, damages or liabilities to which they may become subject under
the Act, or the 1934 Act or other federal or state law, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any of the following statements, omissions or violations
(collectively, a "Violation"): (A) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (B) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the
statements therein not misleading, or (C) any violation or alleged violation by
NewComm of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, or the 1934 Act or any state securities
law; and


<PAGE>


                                     - 22 -


NewComm will pay to each such Indemnitee, as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that this indemnity agreement shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of NewComm (which consent shall not be unreasonably
withheld), nor shall NewComm be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Indemnitee.

                  (ii) To the extent permitted by law, CC will indemnify and
hold harmless NewComm, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls NewComm
within the meaning of the Act, any underwriter, any other NewComm shareholder
selling securities in such registration statement and any controlling person of
any such underwriter or other NewComm shareholder, against any losses, claims,
damages, or liabilities to which any of the foregoing persons may become
subject, under the Act, or the 1934 Act or other federal or state law, insofar
as such losses, claims, damages, or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by CC expressly for use in
connection with such registration; and each CC will pay, as incurred, any legal
or other expenses reasonably incurred by any person intended to be indemnified
hereunder, in connection with investigating or defending any such loss,


<PAGE>


                                     - 23 -


claim, damage, liability, or action; provided, however, that this indemnity
agreement shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of CC, which consent shall not be unreasonably withheld.

                  (iii) Promptly after receipt by an indemnified party of notice
of the commencement of any action (including any governmental action), such
indemnified party will, if a claim in respect thereof is to be made against any
indemnifying party, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties which may
be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with the fees and expenses to be paid by the indemnifying
party, if representation of such indemnified party by the counsel retained by
the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if materially prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
to the extent of such prejudice, but the omission so to deliver written notice
to the indemnifying party will not relieve it of any liability that it may
otherwise have to any indemnified party.

                                     - 24 -


                  (iv) The obligations of NewComm and the CC under this Section
6.02 shall survive the completion of any offering of NewComm stock under this
Agreement and termination of this Agreement.

         Section 6.03 "Market Stand-Off" Agreement. During the period of
duration specified by NewComm and an underwriter of NewComm Stock or other
equity and equity-linked securities of NewComm (which period shall not exceed
one hundred eighty (180) days), following the effective date of a registration
statement of NewComm filed under the Act, neither CC nor TLD shall, to the
extent requested by NewComm and such underwriter, directly or indirectly sell,
offer to sell, contract to sell (including, without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of (other than to
those who agree to be similarly bound) any equity and equity-linked securities
of NewComm held by it at any time during such period (except, (i) transfers
between or among CC and TLD; (ii) NewComm stock included in such registration;
and (iii) transfers to Affiliates of the transferor).

         Section 6.04 Listing. In connection with a registration pursuant to
Article VI of this Agreement, NewComm will use all commercially reasonable
efforts to qualify the NewComm or TLD stock sold pursuant to such registration
to trade on a United States national securities exchange or on the National
Association of Securities Dealers Automated Quotation ("NASDAQ") system and to
maintain the inclusion of such NewComm Stock on a United States national
securities exchange or the NASDAQ system for a period of four years after the
effective date of a registration statement filed with the SEC pursuant to this
Agreement. The NASDAQ system shall mean the NASDAQ National Market.

<PAGE>


                                     - 36 -


warranties, covenants or agreements made by CC in this Agreement or in any of

         Section 11.02 CC's and NewComm's Right to Indemnification. TLD shall

indemnify Indemnitee upon receipt of any such notice. The failure of Indemnitee

that it may have pursuant to this Agreement unless the failure to give such
notice within such time shall have been prejudicial and in such case only to the
extent thereof, and in no event shall the failure to give such notification

<PAGE>


                                     - 37 -


indemnify the Indemnitee within ten (10) days after the Indemnitee's right to
indemnity hereunder is notified to the Indemnitor, without any legally valid
reason to deny its obligations to indemnify, the Indemnitor shall be liable to
pay the amount claimed plus interest at five percent (5%) over The Chase
Manhattan Bank, N.A. base rate, fluctuating concurrently with any changes in
such base rate, for the period commencing after the expiration of the ten (10)
day period and ending on the day of payment in full of the indemnity amount.

         Section 11.04 Third-Party Claims. If any claim for indemnification and
hold harmless by Indemnitee arises out of a claim by a person other than
Indemnitee, Indemnitor may, by written notice to Indemnitee, undertake to
conduct any proceedings or negotiations in connection therewith or necessary to
defend Indemnitee and take all other steps or proceedings to settle or defeat
any such claims or to employ counsel to contest any such claims; provided that
Indemnitor shall reasonably consider the advice of Indemnitee as to the defense
of such claims, and Indemnitee shall have the right to participate, at its own
expense, in such defense, but control of such litigation and settlement shall
remain exclusively with Indemnitor. Indemnitee shall provide all reasonable
cooperation in connection with any such defense by Indemnitor. Counsel, filing
fees, court fees and other costs or expenses of all proceedings, contests or
lawsuits with respect to any such claim or asserted liability shall be borne by
Indemnitor. If any such claims is made hereunder and Indemnitor does not elect
to undertake the defense thereof by written notice to Indemnitee, Indemnitee
shall be entitled to control such litigation and settlement and shall be
entitled to indemnity with respect thereto pursuant to the terms of this Article
XI. To the extent that Indemnitor undertakes the defense of such claim by
written notice to Indemnitee and diligently

indemnification hereunder only to the extent that such defense is unsuccessful

jurisdiction, or by written acknowledgment of the parties.

         Section 14.03 Amendments; No Waivers.

         (a) Any provision of this Agreement may be amended or waived subject to
the requirements of applicable law if, and only if, such amendment or waiver is
in writing and signed, in the case of an amendment, by TLD and CC, or in the
case of a waiver, by the party against whom the waiver is to be effective.

         (b) No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.

         Section 14.04 Expenses. Except as otherwise expressly provided in this
Agreement, all costs and expenses incurred in connection with this Agreement
shall be paid by the party incurring such cost or expense.

         Section 14.05 Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided that no party may assign, delegate
or otherwise transfer any of its rights or obligations under this Agreement
without the consent of the other parties hereto and compliance with applicable
laws and regulations.

         Section 14.06 Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Puerto Rico without giving effect to
principles of conflicts of laws.

         Section 14.07 Counterparts; Effectiveness. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become

                                     - 43 -


effective when each party hereto shall have received a counterpart hereof signed
by the other party hereto.

         Section 14.08 Entire Agreement. This Agreement, including the Exhibits
hereto, constitutes the entire agreement between the parties with respect to the
subject matter hereof and supersedes all prior agreements, understandings and
negotiations, both written and oral, between the parties with respect to the
subject matter of this Agreement. No representation, inducement, promise,
understanding, condition or warranty not set forth herein has been made or
relied upon by either party hereto.

         Section 14.09 Captions; Definitions.  The captions herein are included 
for convenience of reference only and shall be ignored in the construction or 
interpretation hereof.

         Section 14.10 Dispute Resolution; Arbitration.

         (a) The parties agree with the principle that disputes, claims and
controversies arising out of or related to this Agreement or any of the notes or
agreements set forth in Exhibits C, D, E, F and G (including the performance,
enforcement, breach, or termination thereof, and any remedies relating thereto)
(each, a "Dispute") should be regarded as business problems to be resolved
promptly through business-oriented negotiations before resorting to arbitration.
The parties agree to use their best efforts and to attempt in good faith to
resolve any Dispute promptly by negotiation between the executives of the
parties who have authority to settle the Dispute. Either party may give the
other party written notice of any Dispute not resolved in the normal course of
business ("Notice of Dispute"). Within fifteen (15) days after receipt of the
Notice of Dispute by the receiving party ("Date of Notice"), the receiving party
shall submit to the other a


<PAGE>


                                     - 44 -


written response, which shall include a statement of such party's position.
Within thirty (30) days after the Date of Notice, the parties shall meet at a
mutually acceptable time and place, and thereafter as often as they reasonably
deem necessary, to attempt to resolve the Dispute. All reasonable requests for
information made by one party to the other will be honored.

         (b) If the Dispute has not been resolved by these persons within
forty-five (45) days of the Date of Notice, the Dispute shall be referred to a
more senior executive of each party who has authority to settle the Dispute and
who shall likewise meet to attempt to resolve the Dispute.

         (c) All negotiations pursuant to this Section 14.10 shall be
confidential and shall be treated as compromise and settlement negotiations for
purposes of applicable rules of evidence.

         (d) In the event the Dispute has still not been resolved by
negotiation, then such Dispute shall be settled by binding arbitration according
to the rules of the American Arbitration Association before an Arbitral Panel
composed of three (3) Arbitrators. One of such Arbitrators shall be selected by
CC, another by TLD and the third one by two Arbitrators selected by CC and TLD.
The Arbitration shall be legally binding, shall take place in San Juan, Puerto
Rico and shall be conducted in the Spanish language. The arbitral award or order
("Award") shall be given in writing, shall detail the disputed matters and the
reasons upon which the Award is based. The Award of the Arbitrators shall be
final and binding upon the parties and shall not be subject to appeal to any
court or other authority. Judgment upon the award or order may be entered in any
court of competent jurisdiction, and application may be made to any such court
for enforcement thereof. Each party shall bear its own costs and expenses in
connection with the Arbitration, but shall share equally in the costs and fees
of the Arbitration proceedings. Each party accepts and


<PAGE>


                                     - 45 -


submits to the arbitral jurisdiction referenced above and to any court of
competent jurisdiction with regard to enforcement of the Award. Process in any
such action or proceeding may be served on any party anywhere in the world.

         Section 14.11 Third Party Beneficiaries; Parties Bound.

         (a) No provision of this Agreement shall create any third party
beneficiary rights in any person (except in favor of NewComm), nor shall any
provision of this Agreement modify any rights of any third party under any
existing law, regulation or contract with any third party.

         (b) TLD and CC are entering into the Agreement in their capacity as
corporations and limited partnerships, respectively, only and no officer,
director or other individual associated therewith shall have any personal
liability under this Agreement.

         IN WITNESS WHEREOF, the parties hereto here caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
