              THIS INVESTMENT AND LOAN AGREEMENT is made by and among (i)
Startec Global Communications Corporation, a Delaware corporation (collectively
with successors and assigns, the "Company"), and (ii) Allied Capital
Corporation, a Maryland corporation (collectively with successors and assigns,
"Holders"). Capitalized terms not otherwise defined herein shall have the
meanings set out in the definition section hereof, which is Section 22.1.

                                    RECITALS

A. In 1998, pursuant to the terms of the Indenture, Startec Global
Communications Corporation, a Maryland corporation ("Startec Maryland"), issued
certain Indenture Notes.

B. In 1999, Startec Maryland merged with and into Startec Global Holding
Corporation, a Delaware corporation ("Startec Delaware") and Startec Delaware
assumed the obligations of Startec Maryland under the Indenture. Thereafter in
1999, Startec Delaware changed its name to Startec Global Communications
Corporation (thereby becoming Startec Global Communications Corporation, a
Delaware corporation, the Company referred to in this Agreement).

C. Under terms of the Commitment Letter, the Company has committed to issue to
Holders certain debt instruments and certain warrants to purchase shares of the
Company's Common Stock in consideration for a loan in the aggregate principal
amount of Twenty Million Dollars ($20,000,000) (collectively with all
modifications, renewals, extensions and replacements thereof and therefor, the
"Loan"), to be used for general corporate purposes including (without
limitation) the acquisition of Telecommunication Assets, which Loan is intended
to have payment rights in parity with those of the High Yield/Public Debt.

                                   PROVISIONS

              In consideration of the premises and the covenants herein,
Holders, and the Company agree as set forth below.

                                   ARTICLE 1
                                      LOAN

Section 1.1 FUNDING. At Closing, Holders will fund the Loan to the Company. The
Loan will be evidenced by, and repaid according to the terms of, promissory
notes (collectively, with all modifications, extensions, renewals and
replacements thereof and therefor, the "Notes"), which will be issued by the
Company to Holders at Closing.

Section 1.2 PARITY OF LOAN WITH HIGH-YIELD/PUBLIC DEBT. The Loan, the
indebtedness evidenced by the Notes, and the Holders' rights herein shall rank
PARI PASSU in right of payment with the rights of the Trustee (as defined below)
and the holders of the Indenture Notes and their successors and assigns with
respect to the Company's obligations under the Indenture and the
High-Yield/Public Debt.

                                   ARTICLE 2
                                     EQUITY

Section 2.1 COMMON STOCK PURCHASE WARRANTS. At Closing, the Company will issue
and sell, and each Holder will purchase, a stock purchase warrant (collectively
with all modifications, extensions, renewals and replacements thereof and
therefor, the "Warrants") to acquire its respective portion of 125,000 shares of
the Company's common stock ("Holders' Shares" or "Shares"), with such number of
such Shares being subject to certain anti-dilution adjustments set forth in the
Warrants (the shares to be acquired with the Warrants shall sometimes be
referred to as "Warrant Shares"). The Warrants shall be exercisable at a price
per share equal to the average closing price for the Company's common stock on
the National Market System of Nasdaq for the fourteen (14) day period ending the
day before the Closing Date. The aggregate purchase price for the Warrants shall
be One Hundred Dollars ($100), which Holders shall pay to the Company at
Closing.

Section 2.2 REGISTRATION OF WARRANT SHARES. Within 60 days after Closing, the
Company shall file with the Securities and Exchange Commission and all other
applicable securities agencies or exchanges a registration statement meeting the
requirements of the Securities Act covering the resale of the Warrants and the
Warrant Shares upon exercise of the Warrants by Holders. The Company shall use
its best efforts to cause such registration statement to be declared effective
within 120 days after the Closing, and to keep such registration effective until
the earlier of (i) the date when all Warrants and Warrant Shares covered by the
registration statement are eligible for sale under Rule 144(k) of the Securities
Act, and (ii) 60 days after the expiration date of the Warrants. If such
registration statement is not filed within sixty (60) days or if such
registration statement is not filed and declared effective within one hundred
twenty (120) days of the Closing, such events shall not be a default but the
provisions of Sections 2.3, 2.4 and 2.5 hereof shall come into effect and the
Company shall have no further obligations under this Section 2.2.

Section 2.3 DEMAND REGISTRATION RIGHTS. If the registration statement referred
to in Section 2.2 is not filed and declared effective within one hundred twenty
(120) days of the Closing, and the Holders shall thereafter make a written
request to the Company, the Company shall cause to be filed with the Securities
and Exchange Commission (the "Commission") a registration statement meeting the
requirements of the Securities Act (a "Demand Registration"). Each Holder shall
be entitled to have included therein all of such Holder's Warrants and Warrant
Shares. The Holders rights to such registration shall be subject to the
following terms.

                  (a) NUMBER OF DEMAND REGISTRATIONS. The Company shall be
obligated to effect one Demand Registration hereunder; and

                  (b) EFFECTIVE REGISTRATIONS. A Demand Registration shall not
be deemed to have been effected: (i) unless a registration statement pursuant to
the exercise of the demand rights under this Section 2.3 has become effective,
(ii) if after such registration statement has become effective, such
registration or the related offer, sale or distribution of Warrants or Shares
thereunder is interfered with by any stop order, injunction or other order or
requirement of the Commission or other governmental agency or court for any
reason not attributable to the Holders, (iii) if the conditions to closing
specified in the underwriting agreement, if any, entered into in connection with
such registration are not satisfied or waived, other than by reason of a

                                       2
<PAGE>

failure on the part of the Holders, or (iv) if the Company has exercised its
rights under Section 2.9(i) or (ii) hereof with respect to the relevant
registration.

                  (c) RIGHT TO SELECT UNDERWRITER OR AGENT. If any Demand
Registration involves an underwritten offering, or an agented offering, the
Company shall have the right to select the underwriter or underwriters and
manager or managers to administer such underwritten offering or the placement
agent or agents for such agented offering.

                  (d) MAINTENANCE OF EFFECTIVENESS. The Company shall use its
best efforts to keep the Demand Registration statement continuously effective
for up to 180 days or until such earlier date as of which all the Warrants or
Shares under the Demand Registration statement shall have been disposed of in
the manner described in the registration statement.

                  (e) INCLUSION OF OTHER SHARES. The Company may include in any
Demand Registration any Shares to be sold by the Company or Shares of other
Persons having "piggyback" or similar registration rights, but only if and to
the extent the offering and sale thereof will not materially impair the offering
and sale of the Holders' Shares. If any registration under this Section 2.3
involves an underwritten offering and the managing underwriter of such offering
shall advise the Holders by letter that, in its view, the number of securities
requested to be included in such registration exceeds the largest number which
can be sold in an orderly manner in such offering (the "Maximum Amount") and
that such number would materially and adversely affect such offering then the
Company shall include in such registration, to the extent the number and type of
securities which the Company is so advised can be sold in (or during the time
of) such offering: (i) first, all Shares requested to be included in such
registration by the Holders; and (ii) second, to the extent that the number of
Shares to be included by all Holders is less than the Maximum Amount, securities
which the Company or any other holders of Shares, proposes to register.

Section 2.4 PIGGY-BACK REGISTRATION. If the registration statement referred to
in Section 2.2 is not filed and declared effective within one hundred twenty
(120) days of the Closing, and the Company shall at any time thereafter prepare
and file a registration statement under the Securities Act with respect to the
public offering of any class of equity or debt security of the Company, or of
any other commonly-controlled entity, the Company shall give fourteen (14) days
prior written notice thereof to each Holder and shall, upon the written request
of any Holder, include in the registration statement such number of the Holder's
Warrants and Warrant Shares as such Holder may request. The Company will keep
such registration statement effective and current under the Securities Act
permitting the sale of all such Holders' Shares included therein for the same
period that the registration is maintained effective in respect of Shares of
other Persons (including the Company). In any underwritten offering the Holders'
Shares to be included will be sold at the same time and the same per-share price
as the Company's Shares. If the Company fails to receive a written inclusion
request from any Holder within fourteen (14) days after the mailing of its
written notice, then the Company shall have no obligation to include any of such
Holder's Shares in the offering.

                  (a) ALLOCATION. If any registration under this Section 2.4
involves an underwritten offering and the managing underwriter of such offering
shall advise the Company by letter that, in its view, the number of securities
requested to be included in such registration exceeds the Maximum Amount, then
the Company shall notify the Holders of such fact and give the Holders the
reasonable opportunity to negotiate with the managing underwriter regarding the
inclusion in

                                       3
<PAGE>

such registration of all of the Shares requested by the Holders to be included
therein. If the managing underwriter does not agree to include the number of
shares initially requested by the Holders to be included in such registration,
then the Company shall include in such registration, to the extent of the number
and type of which the Company is so advised can be sold in (or during the time
of) such offering: (i) first, all Shares which the Company proposes to register
for its own account (the "Company Securities"); and (ii) second, to the extent
that the number of Company Securities is less than the Maximum Amount, as many
of the Shares requested for inclusion by the Holders as can be accommodated,
allocated on a pro rata basis among the Holders, based on the number of Shares
each Holder initially requested to be included, and (iii) third, to the extent
the Company Securities and the Shares initially requested to be included by the
Holders are fewer than the Maximum Amount, Shares owned by other Persons.

Section 2.5 CERTAIN OBLIGATIONS OF HOLDERS IN A REGISTERED OFFERING. Each Holder
agrees that, upon receipt of any notice from the Company that the registration
materials for the relevant offering must be supplemented or amended, such Holder
will forthwith discontinue disposition of Warrant Shares and Warrants pursuant
to the applicable registration statement until such Holder's receipt of copies
of a supplemented or amended prospectus for the relevant offering, and, if so

registration of any of the Shares under the Securities Act pursuant to this
Agreement, the Company will indemnify and hold harmless each Holder, each
underwriter of such Shares, and each other Person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities, joint or several, to
which such Holder, underwriter, or controlling Person may become subject under
the Securities Act, the Exchange Act, state securities or Blue Sky laws, or
otherwise, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such Shares were registered under the Securities Act, any
preliminary prospectus, or final prospectus contained in the registration
statement, or any amendment or supplement to such registration statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such Holder, underwriter,
and each such controlling Person in connection with investigation or defending
any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage, or liability arises out of or is based upon any untrue statement
or omission made in such registration statement, preliminary prospectus, or
final prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in a written instrument,
duly executed, by or on behalf of such Holder, underwriter, or controlling
Person specifically stating that it is for use in the preparation thereof.

                  (b) INDEMNIFICATION BY HOLDERS. In the event of any
registration of any of the Shares under the Securities Act pursuant to this
Agreement, each Holder, severally and not jointly, will indemnify and hold
harmless the Company, each of its directors and officers and

                                       4
<PAGE>

each underwriters (if any) and each Person, if any, who controls the Company or
any such underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities, joint or several, to
which the Company, such directors and officers, underwriter, or controlling
Person may become subject under the Securities Act, Exchange Act, state
securities or Blue Sky laws, or otherwise, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement under which such Shares were registered
under the Securities Act, any preliminary prospectus or final prospectus
contained in the registration statement, or any amendment or supplement to the
registration statement, or arise out of or are based upon any omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, if the statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company through an instrument duly executed by such Selling
Holder specifically stating that it is for use in the preparation of such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement; PROVIDED, HOWEVER, that the obligations of
each Holder hereunder shall be limited to an amount equal to the proceeds to
such Holder of Shares sold in connection with such registration.

                  (c) NOTICE OF CLAIMS AND CONDUCT OF DEFENSE. Each party
entitled to indemnification under this Section 2.6 (the "Indemnified Party")
shall give notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom; PROVIDED, that counsel for the Indemnifying Party, who
shall conduct the defense of such claim or litigation, shall be approved by the
Indemnified Party (whose approval shall not be unreasonably withheld), unless in
such Indemnified Party's reasonable judgment a conflict of interest between such
Indemnified and Indemnifying Parties may exist in respect of such claim; and,
PROVIDED, FURTHER, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 2.6. The Indemnified Party may participate in such defense at
such party's expense; PROVIDED, HOWEVER, that the Indemnifying Party shall pay
such expense 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 the Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation, shall except with the prior written
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement that does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect of such claim or litigation, and no Indemnified Party
shall consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the Indemnifying Party.

Section 2.7 CONTRIBUTION. To provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
Holder, or any controlling Person of any such holder, makes a claim for
indemnification pursuant to this Section 2.7 but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 2.7 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the

                                       5
<PAGE>

part of any such Holder or any such controlling Person in circumstances for
which indemnification is provided under this Section 2.7; then, in each such
case, the Company and such Holder will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) in such proportions so that such holder is responsible for the
portion represented by the percentage that the public offering price of its
Shares offered by the registration statement bears to the public offering price
of all securities offered by such registration statement, and the Company is
responsible for the remaining portion; PROVIDED, HOWEVER, that, in any such
case, (i) no such holder will be required to contribute any amount in excess of
the proceeds to it of all Shares sold by it pursuant to such registration
statement, and (ii) no Person or entity guilty of fraudulent misrepresentation,
within the meaning of Section 11(f) of the Securities Act, shall be entitled to
contribution from any Person or entity who is not guilty of such fraudulent
misrepresentation. In addition, no Person shall be obligated to contribute
hereinunder any amounts in payment for any settlement of any action or claim,
effected without such Person's prior written consent, which consent shall not be
unreasonably withheld.

Section 2.8 UNDERWRITTEN OFFERINGS.

                  (a) UNDERWRITTEN DEMAND OFFERINGS. If requested by the
underwriters for any underwritten offering by the Holders pursuant to a
registration requested under Section 2.3, the Company will enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be reasonably satisfactory in substance and form to the Company, the Holders
and the underwriters, and to contain such representations and warranties by the
Company and the Holders and such other terms as are generally prevailing in
agreements of that type, including, without limitation, indemnities to the
effect and to the extent provided in Section 2.6. The Holders will cooperate
with the Company in the negotiation of the underwriting agreement and will give
consideration to the reasonable suggestions of the Company regarding the form
and substance thereof. Each Holder shall be a party to such underwriting
agreement, but shall not be required to make any representations or warranties
to or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such Holders, their Shares,
and their intended method of distribution.

                  (b) UNDERWRITTEN PIGGYBACK OFFERINGS. If the Company proposes
to register any of its securities under the Securities Act as contemplated by
Section 2.4 and such securities are to be distributed by or through one or more
underwriters, subject to the provisions of Section 2.4(a) the Company will, if
requested by the Holders, arrange for such underwriters to include all of the
Shares to be offered and sold by the Holders among the securities of the Company
to be distributed by such underwriters. Each Holder shall become a party to the
underwriting agreement negotiated between the Company and such underwriters, but
shall not be required to make any representations or warranties to or agreements
with the Company or the underwriters other than representations, warranties or
agreements regarding the Holders, their shares and their intended method of
distribution.

Section 2.9 DELAYS IN REGISTRATION. If the Board of Directors of the Company, in
its good faith judgment, from time to time determines that any registration of
the Warrants or Warrant Shares should not be made or continued because it would
materially interfere with any material financing, acquisition, corporate
reorganization, merger, or other transaction involving the Company or any of its
Subsidiaries (a "Valid Business Reason"), (i) the Company may postpone filing
the registration statement until such Valid Business Reason no longer exists,
but in no

                                       6
<PAGE>

event for more than 120 days, and (ii) in case the registration statement has
been filed, the Company may cause such registration statement to be withdrawn or
its effectiveness terminated or may postpone amending or supplementing the
registration statement until such Valid Business Reason no longer exists, but in
no event for more than 120 days.

Section 2.10 FEES AND EXPENSES. In connection with any registration statement or
other filing described herein, and in connection with making and keeping such
filings effective as provided herein, the Company shall bear all the expenses
and professional fees of the Company and Holders (except for the Holder's pro
rata share of any underwriters discount) and shall also provide Holders with a
reasonable number of printed copies of the prospectus, offering circulars and/or
supplemental or amended prospectuses in final and preliminary form. The Company
consents to the use of each such prospectus or offering circular in connection
with the sale of Holders' Warrants and Shares.

Section 2.11 LIMIT TO BLUE-SKY FILINGS REQUIRED. In connection with any
registration statement or subsequent amendment or similar document filed and is
subject hereto, the Company shall take all reasonable steps to make the Holders'
securities covered thereby eligible for public offering and sale under the
securities or Blue Sky laws of such jurisdictions as may be specified by the
relevant Holders by the effective date of such registration statement; provided
that in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not so qualified at the time of filing such documents,
or to take any action which would subject it to unlimited service of process in
any jurisdiction where it is not so subject at such time. The Company shall keep
such Blue-Sky filings current for the length of time it must keep any
registration statement, post-effective amendment, prospectus or offering
circular effective pursuant hereto.

Section 2.12 VALUATION OF THE WARRANTS. The Holders and Company hereby agree
that as of the Closing, the fair market value of the Warrants shall be as set

THEREWITH.

two full fiscal quarters multiplied by two, determined on a pro forma basis as

Indebtedness, by its terms or by the terms of any agreement or instrument
pursuant to which such new Indebtedness is issued or remains outstanding, is
expressly made pari passu with, or subordinate in right of payment to, the
remaining Notes, (B) in case the Indebtedness to be refinanced is subordinated
in right of payment to the Notes, such new Indebtedness, by its terms or by the
terms of any agreement or instrument pursuant to which such new Indebtedness is
issued or remains outstanding, is expressly made subordinate in right of payment
to the Notes at least to the extent that the Indebtedness to be refinanced is
subordinated to the Notes and (C) such new Indebtedness, determined as of the
date of Incurrence of such new Indebtedness, does not mature prior to the Stated
Maturity of the Indebtedness to be refinanced or refunded, and the Average Life
of such new Indebtedness is at least equal to the remaining Average Life of the
Indebtedness to be refinanced or refunded; and provided further that in no event
may Indebtedness of the Company be refinanced by means of any Indebtedness of
any Restricted Subsidiary pursuant to this clause (vii);

                        (viii) Indebtedness of (A) the Company not to exceed, at
any one time outstanding, 2.00 times the Net Cash Proceeds from the issuance and
sale, other than to a Subsidiary, of Common Stock (other than Redeemable Stock)
of the Company (less the amount of such proceeds used to make Restricted
Payments as provided in clause (c) or (d) of Section 5.1) and (B) the Company
not to exceed, at one time outstanding, the fair market value of any
Telecommunications Assets acquired by the Company in exchange for Common Stock
of the Company issued after May 28, 1998; provided, however, that in determining
the fair market value of any such Telecommunications Assets so acquired, if the
estimated fair market value of such Telecommunications Assets exceeds (x) $2
million (as estimated in good faith by the Board of Directors), then the fair
market value of such Telecommunications Assets will be determined by a majority
of the Board of Directors of the Company, which determination will be evidenced
by a resolution thereof, and (y) $10 million (as estimated in good faith by the
Board of Directors), then the Company shall deliver to the Holders a written
appraisal as to the fair market value of such Telecommunications Assets prepared
by a nationally recognized investment banking or public accounting firm (or, if
no such investment banking or public accounting firm is qualified to prepare
such an appraisal, by a nationally recognized appraisal firm); and provided
further that, except with respect to Acquired Indebtedness, such Indebtedness
does not mature

                                       21
<PAGE>

prior to the Stated Maturity of the Notes and the Average Life of such
Indebtedness is longer than that of the Notes;

                        (ix) Indebtedness of the Company or any Restricted
Subsidiary (A) in respect of performance, surety or appeal bonds or letters of
credit supporting trade payables, in each case provided in the ordinary course
of business, (B) under Currency Agreements and Interest Rate Agreements covering
Indebtedness of the Company; provided that such agreements do not increase the
Indebtedness of the obligor outstanding at any time other than as a result of
fluctuations in foreign currency exchange rates or interest rates or by reason
of fees, indemnities and compensation payable thereunder and (C) arising from
agreements providing for indemnification, adjustment of purchase price or
similar obligations, or from Guarantees or letters of credit, surety bonds or
performance bonds securing any obligations of the Company or any of its
Restricted Subsidiaries pursuant to such agreements, in any case Incurred in
connection with the disposition of any business, assets or Restricted Subsidiary
of the Company (other than Guarantees of Indebtedness Incurred by any Person
acquiring all or any portion of such business, assets or Restricted Subsidiary
for the purpose of financing such acquisition), in a principal amount not to
exceed the gross proceeds actually received by the Company or any Restricted
Subsidiary in connection with such disposition;

                        (x) Indebtedness of the Company, to the extent that the
net proceeds thereof are promptly (A) used to repay the Notes upon the
acceleration of the maturity thereof upon a Change of Control or (B) deposited
to defease all of the Notes pursuant to Article 9;

                        (xi) Indebtedness of a Restricted Subsidiary represented
by a Guarantee of the Notes permitted by and made in accordance with
Section 5.2; and

                        (xii) Indebtedness of the Company or any Restricted
Subsidiary in addition to that permitted to be incurred pursuant to clauses (i)
through (xi) above in an aggregate principal amount not in excess of $10 million
(or, to the extent not denominated in United States dollars, the United States
Dollar Equivalent thereof) at any one time outstanding.

                  (c) For purposes of determining any particular amount of
Indebtedness under this Section 6.1, Guarantees, Liens or obligations with
respect to letters of credit and other credit enhancements supporting
Indebtedness otherwise included in the determination of such particular amount
shall not be included; provided, however, that the foregoing shall not in any
way be deemed to limit the provisions of Section 5.2. For purposes of
determining compliance with this Section 6.1, in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above clauses, the Company, in its sole discretion may, at the
time of such Incurrence, (i) classify such item of Indebtedness under and comply
with either of paragraph (a) or (b) of this covenant (or any of such
definitions), as applicable, (ii) classify and divide such item of Indebtedness
into more than one of such paragraphs (or definitions), as applicable and (iii)
elect to comply with such paragraphs (or definitions), as applicable in any
order.

Section 6.2 LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
Restricted SUBSIDIARIES.

                  (a) Until the Loan has been fully and indefeasibly paid as and
when due, the Company shall not, and shall not permit any Restricted Subsidiary
to, create or otherwise cause

                                       22
<PAGE>

or suffer to exist or become effective any consensual encumbrance or restriction
of any kind on the ability of any Restricted Subsidiary to do any one of the
following:

                        (i) pay dividends or make any other distributions on any
Capital Stock of such Restricted Subsidiary owned by the Company or any other
Restricted Subsidiary;

                        (ii) pay any Indebtedness owed to the Company or any
other Restricted Subsidiary;

                        (iii) make loans or advances to the Company or any other
Restricted Subsidiary; or

                        (iv) transfer any of its property or assets to the
Company or any other Restricted Subsidiary.

                  (b) The foregoing provisions shall not restrict any
encumbrances or restrictions:

                        (i) existing on the Closing Date in this Agreement or
any other agreements or instruments in effect on the Closing Date, and any
extensions, refinancings, renewals or replacements of such agreements; provided
that the encumbrances and restrictions in any such extensions, refinancings,
renewals or replacements are no less favorable in any material respect to the
Holders than those encumbrances or restrictions that are then in effect and that
are being extended, refinanced, renewed or replaced;

                        (ii) contained in the terms of any Indebtedness or any
agreement pursuant to which such Indebtedness was issued (or, in the case of
Acquired Preferred Stock, terms of such Acquired Preferred Stock) if the
encumbrance or restriction applies only in the event of a default with respect
to a financial covenant contained in such Indebtedness or agreement (or, in the
case of Acquired Preferred Stock, upon the default in the payment of dividends
upon such Acquired Preferred Stock) and such encumbrance or restriction is not
materially more disadvantageous to the Holders than is customary in comparable
financings (as determined by the Company) and the Company determines that any
such encumbrance or restriction will not materially affect the Company's ability
to make principal or interest payments on the Notes;

                        (iii) existing under or by reason of applicable law;

                        (iv) existing with respect to any Person or the property
or assets of such Person acquired by the Company or any Restricted Subsidiary,
existing at the time of such acquisition and not incurred in contemplation
thereof, which encumbrances or restrictions are not applicable to any Person or
the property or assets of any Person other than such Person or the property or
assets of such Person so acquired;

                        (v) in the case of clause (iv) of sub-Section 6.2(a),
(A) that restrict in a customary manner the subletting, assignment or transfer
of any property or asset that is, or is subject to, a lease, purchase mortgage
obligation, license, conveyance or contract or similar property or asset, (B)
existing by virtue of any transfer of, agreement to transfer, option or right
with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by this Agreement or (C) arising
or agreed to in the ordinary course of

                                       23
<PAGE>

business, not relating to any Indebtedness, and that do not, individually or in
the aggregate, detract from the value of property or assets of the Company or
any Restricted Subsidiaries in any manner material to the Company or any
Restricted Subsidiary; or

                        (vi) with respect to a Restricted Subsidiary and imposed
pursuant to an agreement that has been entered into for the sale or disposition
of all or substantially all of the Capital Stock of, or property and assets of,
such Restricted Subsidiary.

                  (c) Nothing contained in this Section 6.2 shall prevent the
Company or any Restricted Subsidiary from (i) creating, incurring, assuming or
suffering to exist any Liens otherwise permitted in Section 6.5 or (ii)
restricting the sale or other disposition of property or assets of the Company
or any of its Restricted Subsidiaries that secure Indebtedness of the Company or
any of its Restricted Subsidiaries.

Section 6.3 LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF Restricted
SUBSIDIARIES. The Company shall not, and shall not permit any Restricted
Subsidiary, directly or indirectly, to issue, transfer, convey, sell, lease or
otherwise dispose of any shares of Capital Stock (including options, warrants or
other rights to purchase shares of such Capital Stock) of such or any other
Restricted Subsidiary (other than to the Company or a wholly-owned Restricted
Subsidiary or in respect of any director's qualifying shares or sales of shares
of Capital Stock to foreign nationals mandated by applicable law) to any Person
unless (a) the Net Cash Proceeds from such issuance, transfer, conveyance, sale,
lease or other disposition are applied in accordance with Section 6.6, (b)
immediately after giving effect to such issuance, transfer, conveyance, sale,
lease or other disposition, such Restricted Subsidiary would no longer
constitute a Restricted Subsidiary of the Company and (c) any Investment in such
Person remaining after giving effect to such issuance, transfer, conveyance,
sale, lease or other disposition would have been permitted to be made under
Section 5.1 if made on the date of such issuance, transfer, conveyance, sale,
lease or other disposition (valued as provided in the definition of
"Investment"); PROVIDED, HOWEVER, that notwithstanding the foregoing, the
Company may, and may permit its Restricted Subsidiaries to, issue, transfer,
convey, sell or otherwise dispose of Capital Stock (other than Redeemable Stock)
(including options, warrants or other rights to purchase shares of such Capital
Stock) of such or any Restricted Cable Subsidiary so long as (x) immediately
after such transaction, the Company and/or its Restricted Subsidiaries continue
to beneficially own at least a majority of the Voting Stock of such Restricted
Cable Subsidiary and (y) the Net Cash Proceeds from such transaction are applied
in accordance with the provisions of Section 6.6. For purposes of the foregoing,
a "Restricted Cable Subsidiary" shall mean any Restricted Subsidiary of the
Company organized after the May 28, 1998 for the purpose of designing,
developing, constructing, acquiring, licensing, owning and/or operating fiber
optic cable or similar transmission systems used in the telecommunications
business.

Section 6.4 LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES. The
Company shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, enter into, renew or extend any transaction (including, without
limitation, the purchase, sale, lease or exchange of property or assets, or the
rendering of any service) with any holder (or any Affiliate of such holder) of
ten percent (10%) or more of any class of Capital Stock of the Company or any
Restricted Subsidiary or with any Affiliate of the Company or any Restricted
Subsidiary, unless the following conditions have been met:

                                       24
<PAGE>

                  (a) such transaction or series of transactions is on terms no
less favorable to the Company or such Restricted Subsidiary than those that
could be obtained in a comparable arm's-length transaction with a Person that is
not such a holder or an Affiliate;

                  (b) if such transaction or series of transactions involves
aggregate consideration in excess of $2 million, then such transaction or series
of transactions is approved by a majority of the Board of Directors of the
Company (including a majority of the disinterested members thereof, if any) and
is evidenced by a resolution thereof; and

                  (c) if such transaction or series of transactions involves
aggregate consideration in excess of $10 million, then the Company or such
Restricted Subsidiary shall deliver to the Holders a written opinion as to the
fairness to the Company or such Restricted Subsidiary of such transaction from a
financial point of view from a nationally recognized investment banking firm
(or, if an investment banking firm is generally not qualified to give such an
opinion, by a nationally recognized appraisal firm or accounting firm).

              The foregoing limitation does not limit, and will not apply to (i)
any transaction between the Company and any of its Restricted Subsidiaries or
between or among Restricted Subsidiaries; (ii) the payment or reimbursement of
reasonable and customary regular fees and expenses to directors of the Company
who are not employees of the Company; (iii) any Restricted Payments not
prohibited by Section 5.1; (iv) loans and advances to officers or employees of
the Company and its Subsidiaries not exceeding at any one time outstanding $1.5
million in the aggregate; (v) employment and similar agreements entered into
between the Company or any of its Restricted Subsidiaries with their respective
employees in the ordinary course of business; and (vi) operating and similar
agreements entered into in the ordinary course of the Company's business.

Section 6.5 LIMITATION ON LIENS. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien (other than Permitted Liens) on any of its assets or
properties of any character (including, without limitation, licenses and
trademarks), or any shares of Capital Stock or Indebtedness of any Restricted
Subsidiary, whether owned at the date of this Agreement or thereafter acquired,
or any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereof, without making effective provision for all of
the Notes and all other amounts ranking pari passu with the Notes to be directly
secured equally and ratably with the obligation or liability secured by such
Lien or, if such obligation or liability is subordinated to the Notes and other
amounts ranking pari passu with the Notes, without making provision for the
Notes and such other amounts to be directly secured prior to the obligation or
liability secured by such Lien.

Section 6.6 LIMITATION ON ASSET SALES.

                  (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale unless (i) the Company or the Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale at least equal to the fair market value of the assets sold or disposed of
as determined by the good faith judgment of the Board of Directors evidenced by
a resolution thereof and (ii) at least seventy-five percent (75%) of the
consideration received for such Asset Sale consists of cash or cash equivalents
or the assumption of unsubordinated Indebtedness.

                                       25
<PAGE>

                  (b) The Company shall, or shall cause the relevant Restricted
Subsidiary to, within 360 days after the date of receipt of the Net Cash
Proceeds from an Asset Sale, (i) (A) apply an amount equal to such Net Cash
Proceeds to permanently repay unsubordinated Indebtedness of the Company or
Indebtedness of any Restricted Subsidiary, in each case, owing to a Person other
than the Company or any of its Restricted Subsidiaries or (B) invest an equal
amount, or the amount not so applied pursuant to clause (A), in property or
assets of a nature or type or that are used in a business (or in a Person having
property and assets of a nature or type, or engaged in a business) similar or
related to the nature or type of the property and assets of, or the business of,
the Company and its Restricted Subsidiaries existing on the date of such
investment (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and evidenced by a resolution thereof) and
(ii) apply (no later than the end of the 360-day period referred to above) such
excess Net Cash Proceeds (to the extent not applied pursuant to clause (i)) as
provided in the following paragraphs of this Section 6.6. The amount of such Net
Cash Proceeds required to be applied (or to be committed to be applied) during
such 360-day period referred to above in the preceding sentence and not applied
as so required by the end of such period shall constitute "Excess Proceeds."

                  (c) If, as of the first day of any calendar month, the
aggregate amount of Excess Proceeds not theretofore subject to an Excess
Proceeds Offer (as defined below) totals at least $10 million, the Company must,
not later than the 30th Business Day thereafter, make an offer (an "Excess
Proceeds Offer") to purchase from the Holders on a pro rata basis an aggregate
principal amount of Notes equal to the Excess Proceeds on such date, at a
purchase price equal to one hundred percent (100%) of the principal amount of
the Notes, plus, in each case, accrued and unpaid interest to the date of
purchase (the "Excess Proceeds Payment").

                  (d) The Company shall commence an Excess Proceeds Offer by
mailing a notice to each Holder stating: (i) that the Excess Proceeds Offer is
being made pursuant to this Section 6.6 and that all Notes validly tendered will
be accepted for payment on a pro rata basis; (ii) the purchase price and the
date of purchase (which shall be a Business Day no earlier than 30 days nor
later than 60 days from the date such notice is mailed) (the "Excess Proceeds
Payment Date"); (iii) that any Notes not tendered will continue to accrue
interest pursuant to its terms; (iv) that, unless the Company defaults in the
payment of the Excess Proceeds Payment, any Notes accepted for payment pursuant
to the Excess Proceeds Offer shall cease to accrue interest on and after the
Excess Proceeds Payment Date; (v) that Holders electing to have a Note purchased
pursuant to the Excess Proceeds Offer will be required to surrender the Notes,
together with the form entitled "Option of the Holder to Elect Purchase" on the
reverse side of the Notes completed, to the Paying Agent at the address
specified in the notice prior to the close of business on the Business Day
immediately preceding the Excess Proceeds Payment Date; (vi) that Holders shall
be entitled to withdraw their election if the Paying Agent receives, not later
than the close of business on the third Business Day immediately preceding the
Excess Proceeds Payment Date, a telegram, facsimile transmission or letter
setting forth the name of such Holder, the principal amount of Notes delivered
for purchase and a statement that such Holder is withdrawing his election to
have such Notes purchased; and (vii) that Holders whose Notes are being
purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered; provided that each Note purchased
and each new Note issued shall be in a principal amount of One Thousand Dollars
($1,000) or integral multiples thereof.

                                       26
<PAGE>

                  (e) On the Excess Proceeds Payment Date, the Company shall (i)
accept for payment on a pro rata basis Notes or portions thereof tendered
pursuant to the Excess Proceeds Offer; (ii) deposit with the Paying Agent money
sufficient to pay the purchase price of all Notes or portions thereof so
accepted; and (iii) deliver, or cause to be delivered, to the Holders all Notes
or portions thereof so accepted together with an Officer's Certificate
specifying the Notes or portions thereof accepted for payment by the Company.
The Paying Agent shall promptly mail to the Holders of Notes so accepted payment
in an amount equal to the purchase price, and shall promptly authenticate and
mail to such Holders a new Note equal in principal amount to any unpurchased
portion of the Note surrendered; provided that each Note purchased and each new
Note issued shall be in a principal amount of One Thousand Dollars ($1,000) or
integral multiples thereof. To the extent that the aggregate principal amount of
Notes tendered is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. The Company shall
publicly announce the results of the Excess Proceeds Offer as soon as
practicable after the Excess Proceeds Payment Date. For purposes of this Section
6.6, the Company shall act as the Paying Agent.

                  (f) The Company shall comply with Rule 14e-1 under the
Exchange Act and any other rules and regulations thereunder to the extent such
rules and regulations are applicable, in the event that such Excess Proceeds are
received by the Company under this Section 6.6 and the Company is required to
repurchase Notes as described above.

Section 6.7 BUSINESS OF THE COMPANY; RESTRICTION ON TRANSFERS OF EXISTING
BUSINESS. The Company shall not, and shall not permit any Restricted Subsidiary
to, be principally engaged in any business or activity other than a Permitted
Business. In addition, the Company and any Restricted Subsidiary shall not be
permitted to, directly or indirectly, transfer to any Unrestricted Subsidiary
(i) any of the material licenses, agreements or instruments, permits or
authorizations used in the Business of the Company and any Restricted Subsidiary
on the Closing Date or (ii) any material portion of the "property and equipment"
(as such term is used in the Company's consolidated financial statements) of the
Company or any Significant Subsidiary used in the licensed service areas of the
Company and any Restricted Subsidiary as they exist on the Closing Date.

Section 6.8 LIMITATION ON SALE-LEASEBACK TRANSACTIONS. The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, enter into any
Sale-Leaseback Transaction with respect to any property of the Company or any of
its Restricted Subsidiaries.

              Notwithstanding the foregoing, the Company may enter into
Sale-Leaseback Transactions; provided, however, that (a) the Attributable Value
of such Sale-Leaseback Transaction shall be deemed to be Indebtedness of the
Company and (b) after giving pro forma effect to any such Sale-Leaseback
Transaction and the foregoing clause (a), the Company would be able to incur One
Dollar ($1.00) of additional Indebtedness (other than Permitted Indebtedness)
pursuant to paragraph (a) of Section 6.1.

Section 6.9 CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE. The Company
shall not consolidate with, or merge with or into, or sell, convey, transfer,
lease or otherwise dispose of all or substantially all of its property and
assets (as an entirety or substantially as an entirety in one transaction or
series of related transactions) to, any Person or permit any Person to merge
with or into the Company and the Company shall not permit any of its Restricted
Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions, in

                                       27
<PAGE>

the aggregate, would result in the sale, assignment, conveyance, transfer, lease
or other disposition of all or substantially all of the properties and assets of
the Company or the Company and its Restricted Subsidiaries, taken as a whole, to
any other Person or Persons, unless:

                  (a) either (i) the Company shall be the continuing Person or
(ii) the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or that acquired or leased such property and assets
of the Company (A) shall be a corporation organized and validly existing under
the laws of the United States of America or any jurisdiction thereof and (B)
shall expressly assume, by an amendment to this Agreement, duly executed and
delivered to the Holders, all of the obligations of the Company with respect to
all of the Notes and under this Agreement;

                  (b) immediately after giving effect to such transaction on a
pro forma basis, no Default or Event of Default shall have occurred and be
continuing;

                  (c) immediately after giving effect to such transaction on a
pro forma basis, the Company, or any Person becoming the successor obligor of
the Notes, shall have a Consolidated Net Worth equal to or greater than the
Consolidated Net Worth of the Company immediately prior to such transaction;

                  (d) immediately after giving effect to such transaction on a
pro forma basis, the Company, or any Person becoming the successor obligor of

Indebtedness under paragraph (a) of Section 6.1; and

                  (e) the Company delivers to the Holders an Officer's
Certificate (attaching the arithmetic computations to demonstrate compliance
with clauses (c) and (d) above) and an opinion of counsel, each stating that
such consolidation, merger or transfer and such amendment to the Agreement
complies with this Section 6.9 and that all conditions precedent herein provided
for relating to such transaction have been complied with;

provided, however, that clauses (c) and (d) above shall not apply if, in the
good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company;
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

              THIS INVESTMENT AND LOAN AGREEMENT is made by and among (i)
Startec Global Communications Corporation, a Delaware corporation (collectively
with successors and assigns, the "Company"), and (ii) Allied Capital
Corporation, a Maryland corporation (collectively with successors and assigns,
"Holders"). Capitalized terms not otherwise defined herein shall have the
meanings set out in the definition section hereof, which is Section 22.1.

                                    RECITALS

A. In 1998, pursuant to the terms of the Indenture, Startec Global
Communications Corporation, a Maryland corporation ("Startec Maryland"), issued
certain Indenture Notes.

B. In 1999, Startec Maryland merged with and into Startec Global Holding
Corporation, a Delaware corporation ("Startec Delaware") and Startec Delaware
assumed the obligations of Startec Maryland under the Indenture. Thereafter in
1999, Startec Delaware changed its name to Startec Global Communications
Corporation (thereby becoming Startec Global Communications Corporation, a
Delaware corporation, the Company referred to in this Agreement).

C. Under terms of the Commitment Letter, the Company has committed to issue to
Holders certain debt instruments and certain warrants to purchase shares of the
Company's Common Stock in consideration for a loan in the aggregate principal
amount of Twenty Million Dollars ($20,000,000) (collectively with all
modifications, renewals, extensions and replacements thereof and therefor, the
"Loan"), to be used for general corporate purposes including (without
limitation) the acquisition of Telecommunication Assets, which Loan is intended
to have payment rights in parity with those of the High Yield/Public Debt.

                                   PROVISIONS

              In consideration of the premises and the covenants herein,
Holders, and the Company agree as set forth below.

                                   ARTICLE 1
                                      LOAN

Section 1.1 FUNDING. At Closing, Holders will fund the Loan to the Company. The
Loan will be evidenced by, and repaid according to the terms of, promissory
notes (collectively, with all modifications, extensions, renewals and
replacements thereof and therefor, the "Notes"), which will be issued by the
Company to Holders at Closing.

Section 1.2 PARITY OF LOAN WITH HIGH-YIELD/PUBLIC DEBT. The Loan, the
indebtedness evidenced by the Notes, and the Holders' rights herein shall rank
PARI PASSU in right of payment with the rights of the Trustee (as defined below)
and the holders of the Indenture Notes and their successors and assigns with
respect to the Company's obligations under the Indenture and the
High-Yield/Public Debt.

                                   ARTICLE 2
                                     EQUITY

Section 2.1 COMMON STOCK PURCHASE WARRANTS. At Closing, the Company will issue
and sell, and each Holder will purchase, a stock purchase warrant (collectively
with all modifications, extensions, renewals and replacements thereof and
therefor, the "Warrants") to acquire its respective portion of 125,000 shares of
the Company's common stock ("Holders' Shares" or "Shares"), with such number of
such Shares being subject to certain anti-dilution adjustments set forth in the
Warrants (the shares to be acquired with the Warrants shall sometimes be
referred to as "Warrant Shares"). The Warrants shall be exercisable at a price
per share equal to the average closing price for the Company's common stock on
the National Market System of Nasdaq for the fourteen (14) day period ending the
day before the Closing Date. The aggregate purchase price for the Warrants shall
be One Hundred Dollars ($100), which Holders shall pay to the Company at
Closing.

Section 2.2 REGISTRATION OF WARRANT SHARES. Within 60 days after Closing, the
Company shall file with the Securities and Exchange Commission and all other
applicable securities agencies or exchanges a registration statement meeting the
requirements of the Securities Act covering the resale of the Warrants and the
Warrant Shares upon exercise of the Warrants by Holders. The Company shall use
its best efforts to cause such registration statement to be declared effective
within 120 days after the Closing, and to keep such registration effective until
the earlier of (i) the date when all Warrants and Warrant Shares covered by the
registration statement are eligible for sale under Rule 144(k) of the Securities
Act, and (ii) 60 days after the expiration date of the Warrants. If such
registration statement is not filed within sixty (60) days or if such
registration statement is not filed and declared effective within one hundred
twenty (120) days of the Closing, such events shall not be a default but the
provisions of Sections 2.3, 2.4 and 2.5 hereof shall come into effect and the
Company shall have no further obligations under this Section 2.2.

Section 2.3 DEMAND REGISTRATION RIGHTS. If the registration statement referred
to in Section 2.2 is not filed and declared effective within one hundred twenty
(120) days of the Closing, and the Holders shall thereafter make a written
request to the Company, the Company shall cause to be filed with the Securities
and Exchange Commission (the "Commission") a registration statement meeting the
requirements of the Securities Act (a "Demand Registration"). Each Holder shall
be entitled to have included therein all of such Holder's Warrants and Warrant
Shares. The Holders rights to such registration shall be subject to the
following terms.

                  (a) NUMBER OF DEMAND REGISTRATIONS. The Company shall be
obligated to effect one Demand Registration hereunder; and

                  (b) EFFECTIVE REGISTRATIONS. A Demand Registration shall not
be deemed to have been effected: (i) unless a registration statement pursuant to
the exercise of the demand rights under this Section 2.3 has become effective,
(ii) if after such registration statement has become effective, such
registration or the related offer, sale or distribution of Warrants or Shares
thereunder is interfered with by any stop order, injunction or other order or
requirement of the Commission or other governmental agency or court for any
reason not attributable to the Holders, (iii) if the conditions to closing
specified in the underwriting agreement, if any, entered into in connection with
such registration are not satisfied or waived, other than by reason of a

                                       2
<PAGE>

failure on the part of the Holders, or (iv) if the Company has exercised its
rights under Section 2.9(i) or (ii) hereof with respect to the relevant
registration.

                  (c) RIGHT TO SELECT UNDERWRITER OR AGENT. If any Demand
Registration involves an underwritten offering, or an agented offering, the
Company shall have the right to select the underwriter or underwriters and
manager or managers to administer such underwritten offering or the placement
agent or agents for such agented offering.

                  (d) MAINTENANCE OF EFFECTIVENESS. The Company shall use its
best efforts to keep the Demand Registration statement continuously effective
for up to 180 days or until such earlier date as of which all the Warrants or
Shares under the Demand Registration statement shall have been disposed of in
the manner described in the registration statement.

                  (e) INCLUSION OF OTHER SHARES. The Company may include in any
Demand Registration any Shares to be sold by the Company or Shares of other
Persons having "piggyback" or similar registration rights, but only if and to
the extent the offering and sale thereof will not materially impair the offering
and sale of the Holders' Shares. If any registration under this Section 2.3
involves an underwritten offering and the managing underwriter of such offering
shall advise the Holders by letter that, in its view, the number of securities
requested to be included in such registration exceeds the largest number which
can be sold in an orderly manner in such offering (the "Maximum Amount") and
that such number would materially and adversely affect such offering then the
Company shall include in such registration, to the extent the number and type of
securities which the Company is so advised can be sold in (or during the time
of) such offering: (i) first, all Shares requested to be included in such
registration by the Holders; and (ii) second, to the extent that the number of
Shares to be included by all Holders is less than the Maximum Amount, securities
which the Company or any other holders of Shares, proposes to register.

Section 2.4 PIGGY-BACK REGISTRATION. If the registration statement referred to
in Section 2.2 is not filed and declared effective within one hundred twenty
(120) days of the Closing, and the Company shall at any time thereafter prepare
and file a registration statement under the Securities Act with respect to the
public offering of any class of equity or debt security of the Company, or of
any other commonly-controlled entity, the Company shall give fourteen (14) days
prior written notice thereof to each Holder and shall, upon the written request
of any Holder, include in the registration statement such number of the Holder's
Warrants and Warrant Shares as such Holder may request. The Company will keep
such registration statement effective and current under the Securities Act
permitting the sale of all such Holders' Shares included therein for the same
period that the registration is maintained effective in respect of Shares of
other Persons (including the Company). In any underwritten offering the Holders'
Shares to be included will be sold at the same time and the same per-share price
as the Company's Shares. If the Company fails to receive a written inclusion
request from any Holder within fourteen (14) days after the mailing of its
written notice, then the Company shall have no obligation to include any of such
Holder's Shares in the offering.

                  (a) ALLOCATION. If any registration under this Section 2.4
involves an underwritten offering and the managing underwriter of such offering
shall advise the Company by letter that, in its view, the number of securities
requested to be included in such registration exceeds the Maximum Amount, then
the Company shall notify the Holders of such fact and give the Holders the
reasonable opportunity to negotiate with the managing underwriter regarding the
inclusion in

                                       3
<PAGE>

such registration of all of the Shares requested by the Holders to be included
therein. If the managing underwriter does not agree to include the number of
shares initially requested by the Holders to be included in such registration,
then the Company shall include in such registration, to the extent of the number
and type of which the Company is so advised can be sold in (or during the time
of) such offering: (i) first, all Shares which the Company proposes to register
for its own account (the "Company Securities"); and (ii) second, to the extent
that the number of Company Securities is less than the Maximum Amount, as many
of the Shares requested for inclusion by the Holders as can be accommodated,
allocated on a pro rata basis among the Holders, based on the number of Shares
each Holder initially requested to be included, and (iii) third, to the extent
the Company Securities and the Shares initially requested to be included by the
Holders are fewer than the Maximum Amount, Shares owned by other Persons.

Section 2.5 CERTAIN OBLIGATIONS OF HOLDERS IN A REGISTERED OFFERING. Each Holder
agrees that, upon receipt of any notice from the Company that the registration
materials for the relevant offering must be supplemented or amended, such Holder
will forthwith discontinue disposition of Warrant Shares and Warrants pursuant
to the applicable registration statement until such Holder's receipt of copies
of a supplemented or amended prospectus for the relevant offering, and, if so
directed by the Company, such Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder' possession, of the superceded prospectus

Section 2.6 INDEMNIFICATION.

                  (a) INDEMNIFICATION BY THE COMPANY. In the event of any
registration of any of the Shares under the Securities Act pursuant to this
Agreement, the Company will indemnify and hold harmless each Holder, each
underwriter of such Shares, and each other Person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities, joint or several, to
which such Holder, underwriter, or controlling Person may become subject under
the Securities Act, the Exchange Act, state securities or Blue Sky laws, or
otherwise, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such Shares were registered under the Securities Act, any
preliminary prospectus, or final prospectus contained in the registration
statement, or any amendment or supplement to such registration statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such Holder, underwriter,
and each such controlling Person in connection with investigation or defending
any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage, or liability arises out of or is based upon any untrue statement
or omission made in such registration statement, preliminary prospectus, or
final prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in a written instrument,
duly executed, by or on behalf of such Holder, underwriter, or controlling
Person specifically stating that it is for use in the preparation thereof.

                  (b) INDEMNIFICATION BY HOLDERS. In the event of any
registration of any of the Shares under the Securities Act pursuant to this
Agreement, each Holder, severally and not jointly, will indemnify and hold
harmless the Company, each of its directors and officers and

                                       4
<PAGE>

each underwriters (if any) and each Person, if any, who controls the Company or
any such underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities, joint or several, to
which the Company, such directors and officers, underwriter, or controlling
Person may become subject under the Securities Act, Exchange Act, state
securities or Blue Sky laws, or otherwise, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement under which such Shares were registered
under the Securities Act, any preliminary prospectus or final prospectus
contained in the registration statement, or any amendment or supplement to the
registration statement, or arise out of or are based upon any omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, if the statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company through an instrument duly executed by such Selling
Holder specifically stating that it is for use in the preparation of such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement; PROVIDED, HOWEVER, that the obligations of
each Holder hereunder shall be limited to an amount equal to the proceeds to
such Holder of Shares sold in connection with such registration.

                  (c) NOTICE OF CLAIMS AND CONDUCT OF DEFENSE. Each party
entitled to indemnification under this Section 2.6 (the "Indemnified Party")
shall give notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom; PROVIDED, that counsel for the Indemnifying Party, who
shall conduct the defense of such claim or litigation, shall be approved by the
Indemnified Party (whose approval shall not be unreasonably withheld), unless in
such Indemnified Party's reasonable judgment a conflict of interest between such
Indemnified and Indemnifying Parties may exist in respect of such claim; and,
PROVIDED, FURTHER, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 2.6. The Indemnified Party may participate in such defense at
such party's expense; PROVIDED, HOWEVER, that the Indemnifying Party shall pay
such expense 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 the Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation, shall except with the prior written
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement that does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect of such claim or litigation, and no Indemnified Party
shall consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the Indemnifying Party.

Section 2.7 CONTRIBUTION. To provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
Holder, or any controlling Person of any such holder, makes a claim for
indemnification pursuant to this Section 2.7 but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 2.7 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the

                                       5
<PAGE>

part of any such Holder or any such controlling Person in circumstances for
which indemnification is provided under this Section 2.7; then, in each such
case, the Company and such Holder will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) in such proportions so that such holder is responsible for the
portion represented by the percentage that the public offering price of its
Shares offered by the registration statement bears to the public offering price
of all securities offered by such registration statement, and the Company is
responsible for the remaining portion; PROVIDED, HOWEVER, that, in any such
case, (i) no such holder will be required to contribute any amount in excess of
the proceeds to it of all Shares sold by it pursuant to such registration
statement, and (ii) no Person or entity guilty of fraudulent misrepresentation,
within the meaning of Section 11(f) of the Securities Act, shall be entitled to
contribution from any Person or entity who is not guilty of such fraudulent
misrepresentation. In addition, no Person shall be obligated to contribute
hereinunder any amounts in payment for any settlement of any action or claim,
effected without such Person's prior written consent, which consent shall not be
unreasonably withheld.

Section 2.8 UNDERWRITTEN OFFERINGS.

                  (a) UNDERWRITTEN DEMAND OFFERINGS. If requested by the
underwriters for any underwritten offering by the Holders pursuant to a
registration requested under Section 2.3, the Company will enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be reasonably satisfactory in substance and form to the Company, the Holders
and the underwriters, and to contain such representations and warranties by the
Company and the Holders and such other terms as are generally prevailing in
agreements of that type, including, without limitation, indemnities to the
effect and to the extent provided in Section 2.6. The Holders will cooperate
with the Company in the negotiation of the underwriting agreement and will give
consideration to the reasonable suggestions of the Company regarding the form
and substance thereof. Each Holder shall be a party to such underwriting
agreement, but shall not be required to make any representations or warranties
to or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such Holders, their Shares,
and their intended method of distribution.

                  (b) UNDERWRITTEN PIGGYBACK OFFERINGS. If the Company proposes
to register any of its securities under the Securities Act as contemplated by
Section 2.4 and such securities are to be distributed by or through one or more
underwriters, subject to the provisions of Section 2.4(a) the Company will, if
requested by the Holders, arrange for such underwriters to include all of the
Shares to be offered and sold by the Holders among the securities of the Company
to be distributed by such underwriters. Each Holder shall become a party to the
underwriting agreement negotiated between the Company and such underwriters, but
shall not be required to make any representations or warranties to or agreements
with the Company or the underwriters other than representations, warranties or
agreements regarding the Holders, their shares and their intended method of
distribution.

Section 2.9 DELAYS IN REGISTRATION. If the Board of Directors of the Company, in
its good faith judgment, from time to time determines that any registration of
the Warrants or Warrant Shares should not be made or continued because it would
materially interfere with any material financing, acquisition, corporate
reorganization, merger, or other transaction involving the Company or any of its
Subsidiaries (a "Valid Business Reason"), (i) the Company may postpone filing
the registration statement until such Valid Business Reason no longer exists,
but in no

                                       6
<PAGE>

event for more than 120 days, and (ii) in case the registration statement has
been filed, the Company may cause such registration statement to be withdrawn or
its effectiveness terminated or may postpone amending or supplementing the
registration statement until such Valid Business Reason no longer exists, but in
no event for more than 120 days.

Section 2.10 FEES AND EXPENSES. In connection with any registration statement or
other filing described herein, and in connection with making and keeping such
filings effective as provided herein, the Company shall bear all the expenses
and professional fees of the Company and Holders (except for the Holder's pro
rata share of any underwriters discount) and shall also provide Holders with a
reasonable number of printed copies of the prospectus, offering circulars and/or
supplemental or amended prospectuses in final and preliminary form. The Company
consents to the use of each such prospectus or offering circular in connection
with the sale of Holders' Warrants and Shares.

Section 2.11 LIMIT TO BLUE-SKY FILINGS REQUIRED. In connection with any
registration statement or subsequent amendment or similar document filed and is
subject hereto, the Company shall take all reasonable steps to make the Holders'
securities covered thereby eligible for public offering and sale under the
securities or Blue Sky laws of such jurisdictions as may be specified by the
relevant Holders by the effective date of such registration statement; provided
that in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not so qualified at the time of filing such documents,
or to take any action which would subject it to unlimited service of process in
any jurisdiction where it is not so subject at such time. The Company shall keep
such Blue-Sky filings current for the length of time it must keep any
registration statement, post-effective amendment, prospectus or offering
circular effective pursuant hereto.

Section 2.12 VALUATION OF THE WARRANTS. The Holders and Company hereby agree
that as of the Closing, the fair market value of the Warrants shall be as set
forth on EXHIBIT 2.12 HERETO AND THAT THEY SHALL PREPARE AND MAINTAIN THEIR

THEREWITH.

decree of the United Kingdom, France, Germany or India that has been adopted,

Knowledge proposed by any governmental body that (a) could reasonably be
expected to have a Material Adverse Effect on the performance by the Company of

contemplated hereby or (b) could reasonably be expected to have a Material
Adverse Effect on the Authorizations, the Company, its Subsidiaries, or the

Restricted Subsidiary with respect to such Indebtedness shall be subordinated in
right of payment to such Restricted Subsidiary's assumption, Guarantee or other
liability with respect to the Notes and the High Yield/Public Debt substantially
to the same extent as such Indebtedness is subordinated to the Notes and (ii)
such Restricted Subsidiary waives, and shall not in any manner whatsoever claim

in, or all or substantially all of the assets of, such Restricted Subsidiary

Section 5.6 CHANGES TO INDENTURE. The Company will not without the prior written
consent of Holders, which consent shall not be unreasonably withheld or delayed:
(i) agree to any change in the payment priority of the Indenture Notes which

Restricted Subsidiaries on a consolidated basis outstanding as of the
Transaction Date to (ii) the Pro Forma Consolidated Cash Flow for the preceding
two full fiscal quarters multiplied by two, determined on a pro forma basis as

part or the Indebtedness to be refinanced is pari passu with the Notes, such new
Indebtedness, by its terms or by the terms of any agreement or instrument
pursuant to which such new Indebtedness is issued or remains outstanding, is
expressly made pari passu with, or subordinate in right of payment to, the
remaining Notes, (B) in case the Indebtedness to be refinanced is subordinated

further that, except with respect to Acquired Indebtedness, such Indebtedness
does not mature

                                       21
<PAGE>

prior to the Stated Maturity of the Notes and the Average Life of such
Indebtedness is longer than that of the Notes;

                        (ix) Indebtedness of the Company or any Restricted
Subsidiary (A) in respect of performance, surety or appeal bonds or letters of
credit supporting trade payables, in each case provided in the ordinary course
of business, (B) under Currency Agreements and Interest Rate Agreements covering
Indebtedness of the Company; provided that such agreements do not increase the
Indebtedness of the obligor outstanding at any time other than as a result of
fluctuations in foreign currency exchange rates or interest rates or by reason
of fees, indemnities and compensation payable thereunder and (C) arising from
agreements providing for indemnification, adjustment of purchase price or
similar obligations, or from Guarantees or letters of credit, surety bonds or
performance bonds securing any obligations of the Company or any of its
Restricted Subsidiaries pursuant to such agreements, in any case Incurred in
connection with the disposition of any business, assets or Restricted Subsidiary

Dollar Equivalent thereof) at any one time outstanding.

                  (c) For purposes of determining any particular amount of
Indebtedness under this Section 6.1, Guarantees, Liens or obligations with
respect to letters of credit and other credit enhancements supporting
Indebtedness otherwise included in the determination of such particular amount
shall not be included; provided, however, that the foregoing shall not in any
way be deemed to limit the provisions of Section 5.2. For purposes of
determining compliance with this Section 6.1, in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above clauses, the Company, in its sole discretion may, at the
time of such Incurrence, (i) classify such item of Indebtedness under and comply
with either of paragraph (a) or (b) of this covenant (or any of such

to, create or otherwise cause

                                       22
<PAGE>

or suffer to exist or become effective any consensual encumbrance or restriction
of any kind on the ability of any Restricted Subsidiary to do any one of the
following:

                        (i) pay dividends or make any other distributions on any
Capital Stock of such Restricted Subsidiary owned by the Company or any other
Restricted Subsidiary;

                        (ii) pay any Indebtedness owed to the Company or any
other Restricted Subsidiary;

                        (iii) make loans or advances to the Company or any other

any other agreements or instruments in effect on the Closing Date, and any
extensions, refinancings, renewals or replacements of such agreements; provided
that the encumbrances and restrictions in any such extensions, refinancings,
renewals or replacements are no less favorable in any material respect to the
Holders than those encumbrances or restrictions that are then in effect and that
are being extended, refinanced, renewed or replaced;

                        (ii) contained in the terms of any Indebtedness or any
agreement pursuant to which such Indebtedness was issued (or, in the case of
Acquired Preferred Stock, terms of such Acquired Preferred Stock) if the
encumbrance or restriction applies only in the event of a default with respect
to a financial covenant contained in such Indebtedness or agreement (or, in the
case of Acquired Preferred Stock, upon the default in the payment of dividends
upon such Acquired Preferred Stock) and such encumbrance or restriction is not
materially more disadvantageous to the Holders than is customary in comparable
financings (as determined by the Company) and the Company determines that any
such encumbrance or restriction will not materially affect the Company's ability
to make principal or interest payments on the Notes;

                        (iii) existing under or by reason of applicable law;

                        (iv) existing with respect to any Person or the property
or assets of such Person acquired by the Company or any Restricted Subsidiary,
existing at the time of such acquisition and not incurred in contemplation
thereof, which encumbrances or restrictions are not applicable to any Person or
the property or assets of any Person other than such Person or the property or
assets of such Person so acquired;

                        (v) in the case of clause (iv) of sub-Section 6.2(a),
(A) that restrict in a customary manner the subletting, assignment or transfer
of any property or asset that is, or is subject to, a lease, purchase mortgage
obligation, license, conveyance or contract or similar property or asset, (B)
existing by virtue of any transfer of, agreement to transfer, option or right
with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by this Agreement or (C) arising
or agreed to in the ordinary course of

                                       23
<PAGE>

business, not relating to any Indebtedness, and that do not, individually or in
the aggregate, detract from the value of property or assets of the Company or
any Restricted Subsidiaries in any manner material to the Company or any
Restricted Subsidiary; or

                        (vi) with respect to a Restricted Subsidiary and imposed
pursuant to an agreement that has been entered into for the sale or disposition
of all or substantially all of the Capital Stock of, or property and assets of,
such Restricted Subsidiary.

                  (c) Nothing contained in this Section 6.2 shall prevent the
Company or any Restricted Subsidiary from (i) creating, incurring, assuming or
suffering to exist any Liens otherwise permitted in Section 6.5 or (ii)
restricting the sale or other disposition of property or assets of the Company
or any of its Restricted Subsidiaries that secure Indebtedness of the Company or
any of its Restricted Subsidiaries.

Section 6.3 LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF Restricted
SUBSIDIARIES. The Company shall not, and shall not permit any Restricted
Subsidiary, directly or indirectly, to issue, transfer, convey, sell, lease or
otherwise dispose of any shares of Capital Stock (including options, warrants or
other rights to purchase shares of such Capital Stock) of such or any other
Restricted Subsidiary (other than to the Company or a wholly-owned Restricted
Subsidiary or in respect of any director's qualifying shares or sales of shares
of Capital Stock to foreign nationals mandated by applicable law) to any Person
unless (a) the Net Cash Proceeds from such issuance, transfer, conveyance, sale,
lease or other disposition are applied in accordance with Section 6.6, (b)
immediately after giving effect to such issuance, transfer, conveyance, sale,
lease or other disposition, such Restricted Subsidiary would no longer
constitute a Restricted Subsidiary of the Company and (c) any Investment in such
Person remaining after giving effect to such issuance, transfer, conveyance,
sale, lease or other disposition would have been permitted to be made under
Section 5.1 if made on the date of such issuance, transfer, conveyance, sale,
lease or other disposition (valued as provided in the definition of
"Investment"); PROVIDED, HOWEVER, that notwithstanding the foregoing, the
Company may, and may permit its Restricted Subsidiaries to, issue, transfer,
convey, sell or otherwise dispose of Capital Stock (other than Redeemable Stock)
(including options, warrants or other rights to purchase shares of such Capital
Stock) of such or any Restricted Cable Subsidiary so long as (x) immediately
after such transaction, the Company and/or its Restricted Subsidiaries continue
to beneficially own at least a majority of the Voting Stock of such Restricted
Cable Subsidiary and (y) the Net Cash Proceeds from such transaction are applied
in accordance with the provisions of Section 6.6. For purposes of the foregoing,
a "Restricted Cable Subsidiary" shall mean any Restricted Subsidiary of the
Company organized after the May 28, 1998 for the purpose of designing,
developing, constructing, acquiring, licensing, owning and/or operating fiber
optic cable or similar transmission systems used in the telecommunications

limitation, the purchase, sale, lease or exchange of property or assets, or the
rendering of any service) with any holder (or any Affiliate of such holder) of
ten percent (10%) or more of any class of Capital Stock of the Company or any
Restricted Subsidiary or with any Affiliate of the Company or any Restricted
Subsidiary, unless the following conditions have been met:

                                       24
<PAGE>

                  (a) such transaction or series of transactions is on terms no
less favorable to the Company or such Restricted Subsidiary than those that
could be obtained in a comparable arm's-length transaction with a Person that is
not such a holder or an Affiliate;

                  (b) if such transaction or series of transactions involves
aggregate consideration in excess of $2 million, then such transaction or series
of transactions is approved by a majority of the Board of Directors of the
Company (including a majority of the disinterested members thereof, if any) and
is evidenced by a resolution thereof; and

                  (c) if such transaction or series of transactions involves
aggregate consideration in excess of $10 million, then the Company or such
Restricted Subsidiary shall deliver to the Holders a written opinion as to the
fairness to the Company or such Restricted Subsidiary of such transaction from a
financial point of view from a nationally recognized investment banking firm
(or, if an investment banking firm is generally not qualified to give such an
opinion, by a nationally recognized appraisal firm or accounting firm).

              The foregoing limitation does not limit, and will not apply to (i)
any transaction between the Company and any of its Restricted Subsidiaries or

reasonable and customary regular fees and expenses to directors of the Company
who are not employees of the Company; (iii) any Restricted Payments not
prohibited by Section 5.1; (iv) loans and advances to officers or employees of
the Company and its Subsidiaries not exceeding at any one time outstanding $1.5

employees in the ordinary course of business; and (vi) operating and similar
agreements entered into in the ordinary course of the Company's business.

Section 6.5 LIMITATION ON LIENS. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien (other than Permitted Liens) on any of its assets or
properties of any character (including, without limitation, licenses and
trademarks), or any shares of Capital Stock or Indebtedness of any Restricted
Subsidiary, whether owned at the date of this Agreement or thereafter acquired,
or any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereof, without making effective provision for all of
the Notes and all other amounts ranking pari passu with the Notes to be directly
secured equally and ratably with the obligation or liability secured by such
Lien or, if such obligation or liability is subordinated to the Notes and other
amounts ranking pari passu with the Notes, without making provision for the
Notes and such other amounts to be directly secured prior to the obligation or
liability secured by such Lien.

Section 6.6 LIMITATION ON ASSET SALES.

                  (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale unless (i) the Company or the Restricted

Sale at least equal to the fair market value of the assets sold or disposed of
as determined by the good faith judgment of the Board of Directors evidenced by
a resolution thereof and (ii) at least seventy-five percent (75%) of the
consideration received for such Asset Sale consists of cash or cash equivalents
or the assumption of unsubordinated Indebtedness.

<PAGE>

                  (b) The Company shall, or shall cause the relevant Restricted
Subsidiary to, within 360 days after the date of receipt of the Net Cash
Proceeds from an Asset Sale, (i) (A) apply an amount equal to such Net Cash
Proceeds to permanently repay unsubordinated Indebtedness of the Company or
Indebtedness of any Restricted Subsidiary, in each case, owing to a Person other
than the Company or any of its Restricted Subsidiaries or (B) invest an equal
amount, or the amount not so applied pursuant to clause (A), in property or
assets of a nature or type or that are used in a business (or in a Person having
property and assets of a nature or type, or engaged in a business) similar or
related to the nature or type of the property and assets of, or the business of,
the Company and its Restricted Subsidiaries existing on the date of such
investment (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and evidenced by a resolution thereof) and
(ii) apply (no later than the end of the 360-day period referred to above) such
excess Net Cash Proceeds (to the extent not applied pursuant to clause (i)) as
provided in the following paragraphs of this Section 6.6. The amount of such Net
Cash Proceeds required to be applied (or to be committed to be applied) during
such 360-day period referred to above in the preceding sentence and not applied
as so required by the end of such period shall constitute "Excess Proceeds."

                  (c) If, as of the first day of any calendar month, the
aggregate amount of Excess Proceeds not theretofore subject to an Excess
Proceeds Offer (as defined below) totals at least $10 million, the Company must,
not later than the 30th Business Day thereafter, make an offer (an "Excess
Proceeds Offer") to purchase from the Holders on a pro rata basis an aggregate
principal amount of Notes equal to the Excess Proceeds on such date, at a
purchase price equal to one hundred percent (100%) of the principal amount of
the Notes, plus, in each case, accrued and unpaid interest to the date of
purchase (the "Excess Proceeds Payment").

                  (d) The Company shall commence an Excess Proceeds Offer by
mailing a notice to each Holder stating: (i) that the Excess Proceeds Offer is
being made pursuant to this Section 6.6 and that all Notes validly tendered will
be accepted for payment on a pro rata basis; (ii) the purchase price and the
date of purchase (which shall be a Business Day no earlier than 30 days nor
later than 60 days from the date such notice is mailed) (the "Excess Proceeds
Payment Date"); (iii) that any Notes not tendered will continue to accrue
interest pursuant to its terms; (iv) that, unless the Company defaults in the
payment of the Excess Proceeds Payment, any Notes accepted for payment pursuant
to the Excess Proceeds Offer shall cease to accrue interest on and after the
Excess Proceeds Payment Date; (v) that Holders electing to have a Note purchased
pursuant to the Excess Proceeds Offer will be required to surrender the Notes,
together with the form entitled "Option of the Holder to Elect Purchase" on the
reverse side of the Notes completed, to the Paying Agent at the address
specified in the notice prior to the close of business on the Business Day
immediately preceding the Excess Proceeds Payment Date; (vi) that Holders shall
be entitled to withdraw their election if the Paying Agent receives, not later
than the close of business on the third Business Day immediately preceding the
Excess Proceeds Payment Date, a telegram, facsimile transmission or letter
setting forth the name of such Holder, the principal amount of Notes delivered
for purchase and a statement that such Holder is withdrawing his election to
have such Notes purchased; and (vii) that Holders whose Notes are being
purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered; provided that each Note purchased
and each new Note issued shall be in a principal amount of One Thousand Dollars
($1,000) or integral multiples thereof.

pursuant to the Excess Proceeds Offer; (ii) deposit with the Paying Agent money
sufficient to pay the purchase price of all Notes or portions thereof so
accepted; and (iii) deliver, or cause to be delivered, to the Holders all Notes
or portions thereof so accepted together with an Officer's Certificate
specifying the Notes or portions thereof accepted for payment by the Company.
The Paying Agent shall promptly mail to the Holders of Notes so accepted payment
in an amount equal to the purchase price, and shall promptly authenticate and
mail to such Holders a new Note equal in principal amount to any unpurchased
portion of the Note surrendered; provided that each Note purchased and each new
Note issued shall be in a principal amount of One Thousand Dollars ($1,000) or
integral multiples thereof. To the extent that the aggregate principal amount of
Notes tendered is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. The Company shall
publicly announce the results of the Excess Proceeds Offer as soon as
practicable after the Excess Proceeds Payment Date. For purposes of this Section
6.6, the Company shall act as the Paying Agent.

                  (f) The Company shall comply with Rule 14e-1 under the
Exchange Act and any other rules and regulations thereunder to the extent such
rules and regulations are applicable, in the event that such Excess Proceeds are

and shall not permit any of its Restricted Subsidiaries to, enter into any
Sale-Leaseback Transaction with respect to any property of the Company or any of
its Restricted Subsidiaries.

              Notwithstanding the foregoing, the Company may enter into
Sale-Leaseback Transactions; provided, however, that (a) the Attributable Value
of such Sale-Leaseback Transaction shall be deemed to be Indebtedness of the
Company and (b) after giving pro forma effect to any such Sale-Leaseback
Transaction and the foregoing clause (a), the Company would be able to incur One
Dollar ($1.00) of additional Indebtedness (other than Permitted Indebtedness)
pursuant to paragraph (a) of Section 6.1.

lease or otherwise dispose of all or substantially all of its property and
assets (as an entirety or substantially as an entirety in one transaction or
series of related transactions) to, any Person or permit any Person to merge
with or into the Company and the Company shall not permit any of its Restricted
Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions, in

                                       27
<PAGE>

the aggregate, would result in the sale, assignment, conveyance, transfer, lease
or other disposition of all or substantially all of the properties and assets of
the Company or the Company and its Restricted Subsidiaries, taken as a whole, to
any other Person or Persons, unless:

                  (a) either (i) the Company shall be the continuing Person or
(ii) the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or that acquired or leased such property and assets

shall expressly assume, by an amendment to this Agreement, duly executed and
delivered to the Holders, all of the obligations of the Company with respect to
all of the Notes and under this Agreement;

                  (b) immediately after giving effect to such transaction on a
pro forma basis, no Default or Event of Default shall have occurred and be
continuing;

                  (c) immediately after giving effect to such transaction on a

such consolidation, merger or transfer and such amendment to the Agreement
complies with this Section 6.9 and that all conditions precedent herein provided
for relating to such transaction have been complied with;

provided, however, that clauses (c) and (d) above shall not apply if, in the
good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company;
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

                            REDEMPTION OR DEFEASANCE

Section 9.1 MATURITY OF NOTES UPON CHANGE OF CONTROL.

              Subject to the Company's rights of defeasance and covenant
defeasance under this Article:

                  (a) Upon the occurrence of a Change of Control and the written
demand of the Holder of the relevant Note, the unpaid principal balance of each
Note, and all accrued and unpaid interest thereon, plus any interest premium
payable as provided below, shall become due and payable.

                  (b) If a Change of Control shall occur within one (1) year of
the Closing Date, there shall become payable with respect to each Note an
interest premium equal to seven percent (7%) of the balance of principal
remaining unpaid on the date the Change of Control occurs; if a Change of
Control occurs between one (1) year after the Closing Date and the second
anniversary of the Closing Date, there shall become payable with respect to each
Note an interest premium equal to five percent (5%) of the balance of principal
remaining unpaid on the date the Change of Control occurs.

                  (c) The Company shall comply with Rule 14e-1 under the
Exchange Act and any rules and regulations thereunder to the extent such rules
and regulations are applicable in the event that a Change of Control occurs and
the Company is required to repay the Notes under this Section 9.1.

Section 9.2 DEFEASANCE AND DISCHARGE. Upon meeting the conditions set forth in
Section 9.4 hereof, the Company may, by written notice to Holders, exercise the
right to be deemed to have been discharged from its obligations with respect to
all Notes on the date the conditions set forth in Section 9.4 are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Notes, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 9.5 and the other Sections of this Agreement
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Notes and this Agreement insofar as such Notes are
concerned (and the Holders, at the expense of the Company, shall execute proper
instruments acknowledging same), except for the following which shall survive
until otherwise terminated or discharged hereunder: (A) the rights of Holders of
Notes to receive payments (solely from monies deposited in trust) in respect of
the principal of, premium, if any, and accrued interest on such Notes when such
payments are due, and (B) this Article 9. Subject to compliance with this
Article 9, the Company may exercise its rights under this Section 9.2
notwithstanding the prior exercise of its rights under Section 9.3 with respect
to the Notes.

Section 9.3 COVENANT DEFEASANCE. Upon meeting the conditions set forth in
Section 9.4 hereof, the Company may, by written notice to Holders, exercise the
right to be released from its obligations under any covenant contained in
Sections 4.10, 4.4, 4.2, 4.12, and Articles 5 and 6

                                       32
<PAGE>

(other than Section 6.9(a), (b) and (e) with respect to the Notes (hereinafter,
"covenant defeasance"), and the Notes shall thereafter be deemed not to be
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to the Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default, but, except as specified
above, the remainder of this Agreement and such Notes shall be unaffected
thereby.

Section 9.4 CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The following shall
be the conditions to application of either Section 9.2 or Section 9.3 to the
Notes:

                  (1) The Company shall irrevocably have deposited or caused to
be deposited with a trustee (who shall agree to comply with the provisions of
this Article 9 applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Notes, (A) cash in
United States dollars, (B) U.S. Government Obligations or (C) a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the trustee, to pay and discharge, and which
shall be applied by the trustee (or other qualifying trustee) to pay and
discharge, the principal of (and premium, if any), and accrued interest on the
Notes on the Stated Maturity (or redemption date, if applicable) of such
principal (and premium, if any) or installment of interest; provided that the
trustee shall have been irrevocably instructed to apply such money or the
proceeds of such U.S. Government Obligations to said payments with respect to
the Notes. Before such a deposit, the Company may give to the trustee a notice
of its election to redeem all of the Notes at a future date, which notice shall
be irrevocable. Such irrevocable redemption notice, if given, shall be given
effect in applying the foregoing. For this purpose, "U.S. Government
Obligations" means securities that are (x) direct obligations of the United
States for the timely payment of which its full faith and credit is pledged or
(y) obligations of a Person controlled or supervised by and acting as an agency
or instrumentality of the United States the timely payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United
States, which, in either case, are not callable or redeemable at the option of
the issuer thereof, and shall also include a depository receipt issued by a
"bank" (as defined in Section 3(a)(2) of the Securities Act), as custodian with
respect to any such U.S. Government Obligation or a specific payment of
principal of or interest on any such U.S. Government Obligation held by such
custodian for the account of the holder of such depository receipt, provided
that (except as required by law) such custodian is not authorized to make any
deduction from the amount payable to the holder of such depository receipt from
any amount received by the custodian in respect of the U.S. Government
Obligation or the specific payment of principal of or interest on the U.S.
Government Obligation evidenced by such depository receipt.

                  (2) No Default or Event of Default with respect to the Notes
shall have occurred and be continuing on the date of such deposit or, insofar as
an event of bankruptcy under paragraph (e) or (f) of Section 7.1 hereof is
concerned, at any time during the period ending on the 123rd day after the date
of such deposit.

                                       33
<PAGE>

                  (3) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under any material agreement
or instrument (other than this Agreement) to which the Company is a party or by
which it is bound.

                  (4) In the case of an election under Section 9.2, the Company
shall have delivered to the trustee an opinion of counsel stating that (x) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (y) since May 28, 1998, there has been a change in the
applicable federal income tax law, in either case to the effect, and based
thereon such opinion shall confirm, that Holders will not recognize income, gain
or loss for federal income tax purposes as a result of such defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such defeasance had not occurred.

                  (5) In the case of an election under Section 9.3, the Company
shall have delivered to the trustee an opinion of counsel to the effect that the
Holders will not recognize income, gain or loss for federal income tax purposes
as a result of such covenant defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have
been the case if such covenant defeasance had not occurred.

                  (6) The Company shall have delivered to the trustee an
Officer's Certificate and an opinion of counsel, each stating that all
conditions precedent provided for relating to either the defeasance under
Section 9.2 or the covenant defeasance under Section 9.3 (as the case may be)
have been complied with.

Section 9.5 DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST;
OTHER MISCELLANEOUS PROVISIONS.

                  (a) All money and U.S. Government Obligations (including the
proceeds thereof) deposited with a trustee pursuant to Section 9.4 in respect of
the Notes shall be held in trust and applied by such trustee, in accordance with
the provisions of such Notes and this Agreement, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the trustee may determine, to the Holders of such Notes of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

                  (b) The Company shall pay and indemnify the trustee against
any tax, fee or other charge imposed on or assessed against the U.S.
Governmental Obligations deposited pursuant to Section 9.4 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders.

                  (c) Anything in this Article 9 to the contrary
notwithstanding, the trustee shall deliver or pay to the Company from time to
time upon its request any money or U.S. Government Obligations held by it as
provided in Section 9.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance, as applicable, in accordance with this Article.

                                       34
<PAGE>

Section 9.6 REINSTATEMENT. If the trustee or any Paying Agent is unable to apply
any money in accordance with Section 9.5 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Agreement and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 9.2 or 9.3, as the case may be, until such time as
the trustee or Paying Agent is permitted to apply all such money in accordance
with Section 9.5; provided, however, that if the Company makes any payment of
principal of (or premium, if any) or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
trustee or Paying Agent.

Section 9.7 APPOINTMENT OF TRUSTEE. At the time Company exercises its rights
under Sections 9.2 or 9.3 hereof, the Holders shall appoint a trustee
satisfactory to Company or appoint a trustee upon Company's request (the
"Trustee"), with full power and authority (including power of substitution),
except as otherwise expressly provided in this Agreement, in the name of and for
and on behalf the Holders, or in its own name as the Trustee, to take all
actions required or permitted under Sections 9.2-9.6 hereof (including giving
and receiving all accountings, reports, notices and consents). The authority
conferred under this Section 9.7 shall be an agency coupled with an interest,
and all authority conferred hereby is irrevocable and not subject to termination
by the Holders or any of them, or by operation of law, whether by the
dissolution or termination of any Holder or the occurrence of any other event.
If the Trustee resigns or is otherwise unable to serve as the Trustee, the
successor Trustee shall be designated in writing by the Holders. If any Holder
should dissolve or terminate or if any other such event should occur, any action
taken by the Trustee pursuant to this Section 9.7 shall be as valid as if such
dissolution, termination or other event had not occurred, regardless of whether
or not the Trustee or the Company shall have received notice of such
dissolution, termination or other event.

Section 9.8 SECTION 9.1 NOT APPLICABLE. Upon the Company meeting the conditions
of Section 9.4 hereof and exercising its right of defeasance or covenant
defeasance under Section 9.2 or 9.3 hereof, Section 9.1 shall no longer be
applicable to the Company.

any previous repayments.

                                   ARTICLE 14
                    Holders' Covenants As To Confidentiality

Section 14.1 CONFIDENTIAL INFORMATION; INSIDER TRADING. For the purposes of this
Article 14, "Confidential Information" means information delivered previous to,
at or after the execution of this Agreement to any of the Holders, or to any of
their directors, officers, employees, representatives, Affiliates, associates or
advisors (collectively, "REPRESENTATIVES") in connection with the transactions
contemplated by or otherwise pursuant to this Agreement that was maintained or
created by or is otherwise proprietary to the Company. Confidential Information
shall be deemed to include all analyses, compilations, forecasts, projections,
studies or other documents prepared by any of the Holders or their
Representatives in connection with its or their review of the transactions
hereunder which contain, reflect or are based upon, in whole or in part, the
Confidential Information; PROVIDED THAT the term "Confidential Information" will
not include information which (i) is or becomes publicly available other than as
a result of a disclosure by any of the Holders or any of their Representatives,
or (ii) is or becomes available to any of the Holders on a nonconfidential basis
from a source (other than the Company) which, to the best of the Holders'
knowledge after due inquiry, is not prohibited from disclosing such information
to any of the Holders by a legal, contractual or fiduciary obligation to the
Company. Each such Person receiving Confidential Information will maintain the
strict confidentiality of such Confidential Information and will not (except as
provided below), without the Company's prior written consent, disclose any
Confidential Information in any manner whatsoever, and will not use any
Confidential Information for any purpose whatsoever other than in connection

<PAGE>

PROVIDED THAT such Person may deliver or disclose Confidential Information to
(i) its Representatives (to the extent such disclosure reasonably relates to the
administration of the investment represented by its Loans and provided that such
Person agrees to be bound by the provisions of this Article 14 with respect to
such Confidential Information), or (ii) any other Person to which such delivery
or disclosure is required (x) to effect compliance with any law, rule,
regulation or order applicable to such Person, (y) in response to any subpoena
or other legal process, or (z) in connection with any litigation to which such
Person is a party, PROVIDED that, in the case of any delivery or disclosure
contemplated by any of the foregoing clauses (ii) such Person shall, unless
prohibited by law, notify the Company prior to such delivery of disclosure so
that the Company may seek a protective order or other appropriate remedy or, in
the Company's sole discretion, waive compliance with the terms of this Article
14. In the event that no such protective order or other remedy is obtained, or
that the Company waives compliance with the terms of this Article 14, the
Holders will furnish only that portion of the Confidential Information which the
Holders reasonably determine to be legally required. The Holders agree that they
will be responsible for any breach of this Article 14 by any of their
Representatives. With respect to any Confidential Information, Holders and their
Representatives shall be deemed to have discharged their obligations to the
Company under this Article 14 in any case where they employ the same degree of
diligence and the same procedures to protect such information as they employ
with respect to confidential information of the Holders.

Section 14.2 PUBLICITY. The Holders will not issue any press release or
otherwise make any public announcement with respect to this Agreement or the
subject matter hereof without first consulting with the Company.

assigns. Any purchaser, assignee, transferee or pledgee of the Warrants or
Notes, or any document arising in connection with the transaction subject to

                           RELATIONSHIP OF THE PARTIES

              This Agreement provides, among other things, for the making of
loans by Holders, in their capacity as lenders, to the Company, in its capacity
as a borrower, and for the payment of interest and repayment of principal by the
Company to Holders. The provisions herein requiring compliance with financial
covenants and delivery of financial statements are intended solely for the
benefit of Holders to protect their interests as lenders in assuring payments of
interest and repayment of principal, and as warrant or stock holders in
preserving their equity stake in the Company. Nothing contained in this
Agreement shall be construed as permitting or obligating Holders to act as
financial or business advisors or consultants to the Company, as permitting or
obligating Holders to control the Company or to conduct the Company's
operations, as creating any fiduciary obligation on the part of Holders to the
Company, or as creating any joint venture, agency or other relationship between
the parties, other than as explicitly and specifically stated in this Agreement.
A Holder is not, and shall not be construed as, a partner, joint venturer,
alter-ego, manager, controlling person, operator or other business participant
of any kind of the Company; neither Holders nor the Company intend Holders to
assume such status, and, accordingly, Holders shall not be deemed responsible
for or a participant in any acts or omissions of the Company. The Company
represents that it has the advice of experienced counsel of its

                                       39

                  (c) The Company shall comply with Rule 14e-1 under the
Exchange Act and any rules and regulations thereunder to the extent such rules
and regulations are applicable in the event that a Change of Control occurs and
the Company is required to repay the Notes under this Section 9.1.

Section 9.2 DEFEASANCE AND DISCHARGE. Upon meeting the conditions set forth in
Section 9.4 hereof, the Company may, by written notice to Holders, exercise the
right to be deemed to have been discharged from its obligations with respect to
all Notes on the date the conditions set forth in Section 9.4 are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Notes, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 9.5 and the other Sections of this Agreement
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Notes and this Agreement insofar as such Notes are
concerned (and the Holders, at the expense of the Company, shall execute proper
instruments acknowledging same), except for the following which shall survive
until otherwise terminated or discharged hereunder: (A) the rights of Holders of
Notes to receive payments (solely from monies deposited in trust) in respect of
the principal of, premium, if any, and accrued interest on such Notes when such
payments are due, and (B) this Article 9. Subject to compliance with this
Article 9, the Company may exercise its rights under this Section 9.2
notwithstanding the prior exercise of its rights under Section 9.3 with respect
to the Notes.

Section 9.3 COVENANT DEFEASANCE. Upon meeting the conditions set forth in
Section 9.4 hereof, the Company may, by written notice to Holders, exercise the
right to be released from its obligations under any covenant contained in
Sections 4.10, 4.4, 4.2, 4.12, and Articles 5 and 6

                                       32
<PAGE>

(other than Section 6.9(a), (b) and (e) with respect to the Notes (hereinafter,
"covenant defeasance"), and the Notes shall thereafter be deemed not to be
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to the Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default, but, except as specified
above, the remainder of this Agreement and such Notes shall be unaffected
thereby.

Section 9.4 CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The following shall
be the conditions to application of either Section 9.2 or Section 9.3 to the
Notes:

                  (1) The Company shall irrevocably have deposited or caused to
be deposited with a trustee (who shall agree to comply with the provisions of
this Article 9 applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Notes, (A) cash in
United States dollars, (B) U.S. Government Obligations or (C) a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the trustee, to pay and discharge, and which
shall be applied by the trustee (or other qualifying trustee) to pay and
discharge, the principal of (and premium, if any), and accrued interest on the
Notes on the Stated Maturity (or redemption date, if applicable) of such
principal (and premium, if any) or installment of interest; provided that the
trustee shall have been irrevocably instructed to apply such money or the
proceeds of such U.S. Government Obligations to said payments with respect to
the Notes. Before such a deposit, the Company may give to the trustee a notice
of its election to redeem all of the Notes at a future date, which notice shall
be irrevocable. Such irrevocable redemption notice, if given, shall be given
effect in applying the foregoing. For this purpose, "U.S. Government
Obligations" means securities that are (x) direct obligations of the United
States for the timely payment of which its full faith and credit is pledged or
(y) obligations of a Person controlled or supervised by and acting as an agency
or instrumentality of the United States the timely payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United
States, which, in either case, are not callable or redeemable at the option of
the issuer thereof, and shall also include a depository receipt issued by a
"bank" (as defined in Section 3(a)(2) of the Securities Act), as custodian with
respect to any such U.S. Government Obligation or a specific payment of
principal of or interest on any such U.S. Government Obligation held by such
custodian for the account of the holder of such depository receipt, provided
that (except as required by law) such custodian is not authorized to make any
deduction from the amount payable to the holder of such depository receipt from
any amount received by the custodian in respect of the U.S. Government
Obligation or the specific payment of principal of or interest on the U.S.
Government Obligation evidenced by such depository receipt.

                  (2) No Default or Event of Default with respect to the Notes
shall have occurred and be continuing on the date of such deposit or, insofar as
an event of bankruptcy under paragraph (e) or (f) of Section 7.1 hereof is
concerned, at any time during the period ending on the 123rd day after the date
of such deposit.

                                       33
<PAGE>

                  (3) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under any material agreement
or instrument (other than this Agreement) to which the Company is a party or by
which it is bound.

                  (4) In the case of an election under Section 9.2, the Company
shall have delivered to the trustee an opinion of counsel stating that (x) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (y) since May 28, 1998, there has been a change in the
applicable federal income tax law, in either case to the effect, and based
thereon such opinion shall confirm, that Holders will not recognize income, gain
or loss for federal income tax purposes as a result of such defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such defeasance had not occurred.

                  (5) In the case of an election under Section 9.3, the Company
shall have delivered to the trustee an opinion of counsel to the effect that the
Holders will not recognize income, gain or loss for federal income tax purposes
as a result of such covenant defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have
been the case if such covenant defeasance had not occurred.

                  (6) The Company shall have delivered to the trustee an
Officer's Certificate and an opinion of counsel, each stating that all
conditions precedent provided for relating to either the defeasance under
Section 9.2 or the covenant defeasance under Section 9.3 (as the case may be)
have been complied with.

Section 9.5 DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST;
OTHER MISCELLANEOUS PROVISIONS.

                  (a) All money and U.S. Government Obligations (including the
proceeds thereof) deposited with a trustee pursuant to Section 9.4 in respect of
the Notes shall be held in trust and applied by such trustee, in accordance with
the provisions of such Notes and this Agreement, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the trustee may determine, to the Holders of such Notes of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

                  (b) The Company shall pay and indemnify the trustee against
any tax, fee or other charge imposed on or assessed against the U.S.
Governmental Obligations deposited pursuant to Section 9.4 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders.

                  (c) Anything in this Article 9 to the contrary
notwithstanding, the trustee shall deliver or pay to the Company from time to
time upon its request any money or U.S. Government Obligations held by it as
provided in Section 9.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance, as applicable, in accordance with this Article.

                                       34
<PAGE>

Section 9.6 REINSTATEMENT. If the trustee or any Paying Agent is unable to apply
any money in accordance with Section 9.5 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Agreement and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 9.2 or 9.3, as the case may be, until such time as
the trustee or Paying Agent is permitted to apply all such money in accordance
with Section 9.5; provided, however, that if the Company makes any payment of
principal of (or premium, if any) or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
trustee or Paying Agent.

Section 9.7 APPOINTMENT OF TRUSTEE. At the time Company exercises its rights
under Sections 9.2 or 9.3 hereof, the Holders shall appoint a trustee
satisfactory to Company or appoint a trustee upon Company's request (the
"Trustee"), with full power and authority (including power of substitution),
except as otherwise expressly provided in this Agreement, in the name of and for
and on behalf the Holders, or in its own name as the Trustee, to take all
actions required or permitted under Sections 9.2-9.6 hereof (including giving
and receiving all accountings, reports, notices and consents). The authority
conferred under this Section 9.7 shall be an agency coupled with an interest,
and all authority conferred hereby is irrevocable and not subject to termination
by the Holders or any of them, or by operation of law, whether by the
dissolution or termination of any Holder or the occurrence of any other event.
If the Trustee resigns or is otherwise unable to serve as the Trustee, the
successor Trustee shall be designated in writing by the Holders. If any Holder
should dissolve or terminate or if any other such event should occur, any action
taken by the Trustee pursuant to this Section 9.7 shall be as valid as if such
dissolution, termination or other event had not occurred, regardless of whether
or not the Trustee or the Company shall have received notice of such
dissolution, termination or other event.

Section 9.8 SECTION 9.1 NOT APPLICABLE. Upon the Company meeting the conditions
of Section 9.4 hereof and exercising its right of defeasance or covenant
defeasance under Section 9.2 or 9.3 hereof, Section 9.1 shall no longer be
applicable to the Company.

                                   ARTICLE 10

              If the Loan has been fully paid and the Company's Shares are
Publicly Traded (as defined in the Warrants), then all Sections of Articles 4, 5

repayment of the Notes, shall be in effect if Holders are required to disgorge
any previous repayments.

                                   ARTICLE 11

Company or any other obligor under the Notes;

                  (d) All costs and fees, including reasonable attorneys' fees

                        (i) any suit, action or claim of Holders to enforce the
provisions of the Loan Documents or any other document in connection with the
transactions contemplated by this Agreement; and

                        (ii) any suit, action, claim or other liability asserted
against any of Holders or their Affiliates by the Company in which the Company
does not prevail with respect to substantially all of its claims.

                                 INDEMNIFICATION

              The Company will indemnify Holders and their directors, officers,
employees, agents and controlling Persons (hereinafter collectively,
"Indemnitees") against, and hold each such Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses (including attorneys'
fees and expenses) incurred by or asserted against Holders or any such
Indemnitee arising out of, in any way connected with, or resulting from the
following:

                  (a) this Agreement, the other documents contemplated hereby,
the performance by the parties hereto and thereto of their respective
obligations hereunder and thereunder, or consummation of the transactions
contemplated hereby and thereby;

                  (b) any and all liability and loss with respect to or
resulting from any and all claims for or on account of any broker's finder's

transaction or the issuance of stock hereunder; and

                  (c) any claim, litigation investigation or proceeding relating
to any of the foregoing, whether or not Holders or any such person is a party
thereto;

<PAGE>

              PROVIDED, HOWEVER, that any such indemnity shall not apply to any
such losses, claims, damages, liabilities or related expenses arising from
Holders' gross negligence or willful misconduct. THIS SECTION IS INTENDED TO
INDEMNIFY THE INDEMNITEES FROM THE RESULTS OF THEIR OWN ORDINARY NEGLIGENCE.

              The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of the
Notes, the invalidity or unenforceability of any term or provision of this
Agreement or any Loan Documents, or any investigation made by or on behalf of
Holders. All amounts due under this Article shall be payable on written demand
therefor.

                                    REMEDIES

Section 13.1 CUMULATION. None of the rights or remedies of the Holders provided
herein shall be exclusive, but each shall be cumulative with and in addition to
every other right or remedy of Holders, now or hereafter existing, at law or in
equity, by statute, agreement or otherwise.

Section 13.2 NO IMPLIED WAIVER. No course of dealing between a Holder and any
other party hereto, or any failure or delay on the part of a Holder in
exercising any rights or remedies hereunder, shall operate as a waiver of any
rights or remedies of any Holder under this or any other applicable agreement.
No single or partial exercise of any rights or remedies hereunder shall operate
as a waiver or preclude the exercise of any other rights or remedies hereunder.

                                   ARTICLE 14
                    Holders' Covenants As To Confidentiality

Section 14.1 CONFIDENTIAL INFORMATION; INSIDER TRADING. For the purposes of this
Article 14, "Confidential Information" means information delivered previous to,
at or after the execution of this Agreement to any of the Holders, or to any of
their directors, officers, employees, representatives, Affiliates, associates or
advisors (collectively, "REPRESENTATIVES") in connection with the transactions
contemplated by or otherwise pursuant to this Agreement that was maintained or
created by or is otherwise proprietary to the Company. Confidential Information
shall be deemed to include all analyses, compilations, forecasts, projections,
studies or other documents prepared by any of the Holders or their
Representatives in connection with its or their review of the transactions
hereunder which contain, reflect or are based upon, in whole or in part, the
Confidential Information; PROVIDED THAT the term "Confidential Information" will
not include information which (i) is or becomes publicly available other than as
a result of a disclosure by any of the Holders or any of their Representatives,
or (ii) is or becomes available to any of the Holders on a nonconfidential basis
from a source (other than the Company) which, to the best of the Holders'
knowledge after due inquiry, is not prohibited from disclosing such information
to any of the Holders by a legal, contractual or fiduciary obligation to the
Company. Each such Person receiving Confidential Information will maintain the
strict confidentiality of such Confidential Information and will not (except as
provided below), without the Company's prior written consent, disclose any
Confidential Information in any manner whatsoever, and will not use any
Confidential Information for any purpose whatsoever other than in connection
with the transactions contemplated by this Agreement,

                                       37
<PAGE>

PROVIDED THAT such Person may deliver or disclose Confidential Information to
(i) its Representatives (to the extent such disclosure reasonably relates to the
administration of the investment represented by its Loans and provided that such
Person agrees to be bound by the provisions of this Article 14 with respect to
such Confidential Information), or (ii) any other Person to which such delivery
or disclosure is required (x) to effect compliance with any law, rule,
regulation or order applicable to such Person, (y) in response to any subpoena
or other legal process, or (z) in connection with any litigation to which such
Person is a party, PROVIDED that, in the case of any delivery or disclosure
contemplated by any of the foregoing clauses (ii) such Person shall, unless
prohibited by law, notify the Company prior to such delivery of disclosure so
that the Company may seek a protective order or other appropriate remedy or, in
the Company's sole discretion, waive compliance with the terms of this Article
14. In the event that no such protective order or other remedy is obtained, or
that the Company waives compliance with the terms of this Article 14, the
Holders will furnish only that portion of the Confidential Information which the
Holders reasonably determine to be legally required. The Holders agree that they
will be responsible for any breach of this Article 14 by any of their
Representatives. With respect to any Confidential Information, Holders and their
Representatives shall be deemed to have discharged their obligations to the
Company under this Article 14 in any case where they employ the same degree of
diligence and the same procedures to protect such information as they employ
with respect to confidential information of the Holders.

Section 14.2 PUBLICITY. The Holders will not issue any press release or
otherwise make any public announcement with respect to this Agreement or the
subject matter hereof without first consulting with the Company.

                                   ARTICLE 15
                                     PARTIES

              This Agreement will bind and accrue to the benefit of the Company,
the Holders, any holders of the Warrants or the Notes, and their successors and
assigns. Any purchaser, assignee, transferee or pledgee of the Warrants or
Notes, or any document arising in connection with the transaction subject to
this Agreement (or any of them), sold, assigned, transferred, pledged or
repledged by a Holder shall forthwith become vested with and entitled to
exercise all rights and remedies provided herein to Holders, as if said
purchaser, assignee, transferee or pledgee were originally named in this
Agreement in place of the Holders.

                                   ARTICLE 16
                                     NOTICE

or Notes shall be in writing and mailed, postage prepaid, or delivered as

Rejection or other refusal to accept, or the inability to deliver because of a
changed address of which no notice was given, shall not affect the date of such
notice sent in accordance with the foregoing provisions. Each such notice,
request or other communication shall be deemed sufficiently given, served, sent
and received for all purposes at such time as it is delivered to the addressee
(with the return receipt, the delivery receipt, the affidavit of the messenger
or the answer back being deemed conclusive evidence of such delivery).

                           RELATIONSHIP OF THE PARTIES

              This Agreement provides, among other things, for the making of
loans by Holders, in their capacity as lenders, to the Company, in its capacity
as a borrower, and for the payment of interest and repayment of principal by the
Company to Holders. The provisions herein requiring compliance with financial
covenants and delivery of financial statements are intended solely for the
benefit of Holders to protect their interests as lenders in assuring payments of
interest and repayment of principal, and as warrant or stock holders in
preserving their equity stake in the Company. Nothing contained in this
Agreement shall be construed as permitting or obligating Holders to act as
financial or business advisors or consultants to the Company, as permitting or
obligating Holders to control the Company or to conduct the Company's
operations, as creating any fiduciary obligation on the part of Holders to the
Company, or as creating any joint venture, agency or other relationship between
the parties, other than as explicitly and specifically stated in this Agreement.
A Holder is not, and shall not be construed as, a partner, joint venturer,
alter-ego, manager, controlling person, operator or other business participant
of any kind of the Company; neither Holders nor the Company intend Holders to
assume such status, and, accordingly, Holders shall not be deemed responsible
for or a participant in any acts or omissions of the Company. The Company
represents that it has the advice of experienced counsel of its

                                       39

own choosing in connection with the negotiation and execution of this Agreement
and with respect to all matters contained herein.

                                   ARTICLE 18
    CONTROLLING LAW; VENUE AND NON-EXCLUSIVE JURISDICTION; SERVICE OF PROCESS

              This Agreement shall be interpreted, and the rights and
liabilities of the parties hereto determined, in accordance with the laws of the
District of Columbia, without regard to its principles of conflicts of law.
Venue for any adjudication hereof may be in the courts of the District of
Columbia or the federal courts in the District of Columbia, to the jurisdiction
of which courts all undersigned parties hereby submit as the agreement of such
parties, as not inconvenient, and as not subject to review by any court other
than such courts in the District of Columbia. All parties intend and agree that
the courts of jurisdictions in which the Company is incorporated and conducts
its business shall afford full faith and credit to any judgment rendered by a
court of the District of Columbia against the Company or other obligees
hereunder, and that such District of Columbia and federal courts shall have IN
PERSONAM jurisdiction to enter a valid judgment against the Company or other
obligees hereunder. Service of any summons and/or complaint and any other
process which may be served on the Company in any action in respect hereto, may
be made by mailing via registered mail, or delivering a copy of such process to
the Company at its address specified above. The parties hereto agree that this
submission to jurisdiction and consent to service of process are reasonable and
made for the express benefit of Holders.

                                   ARTICLE 19
                             WAIVER OF TRIAL BY JURY

              EACH PARTY TO THIS AGREEMENT WAIVES ALL RIGHT TO TRIAL BY JURY OF
ALL CLAIMS, DEFENSES, COUNTERCLAIMS AND SUITS OF ANY KIND DIRECTLY OR INDIRECTLY
ARISING FROM OR RELATING TO THIS AGREEMENT, THE LOAN, THE LOAN DOCUMENTS OR THE
DEALINGS OF THE PARTIES IN RESPECT THERETO. THE PARTIES HERETO ACKNOWLEDGE AND
AGREE THAT THIS ARTICLE IS A MATERIAL TERM OF THIS AGREEMENT AND THAT THE
HOLDERS WOULD NOT EXTEND ANY FUNDS HEREUNDER IF THIS WAIVER OF JURY TRIAL WERE
NOT A PART OF THIS AGREEMENT. EACH PARTY HERETO ACKNOWLEDGES THAT THIS IS A
WAIVER OF A LEGAL RIGHT AND THAT IT MAKES THIS WAIVER VOLUNTARILY AND KNOWINGLY
AFTER CONSULTATION WITH, OR THE OPPORTUNITY TO CONSULT WITH, COUNSEL OF ITS
CHOICE. EACH PARTY HERETO AGREES THAT ALL SUCH CLAIMS, DEFENSES, COUNTERCLAIMS

exchanged (as the case may be) for such stock or interests in full.

         (d) INDEPENDENT FINANCIAL EXPERT is defined as a nationally recognized

              (i) the average of the closing sales price of such Common Stock on
the NASDAQ National Market System (hereinafter, NASDAQ-NMS) for the twenty (20)
consecutive Business Days ending with the date of determination; for any such
Business Day when there have been no sales on NASDAQ-NMS, the average of the
highest bid and lowest asked prices on NASDAQ-NMS on such day shall be used in
such calculation; BUSINESS DAYS shall mean all days except Saturday, Sunday and
any day which in the City of New York shall be a legal holiday or a day on which

prices for Common Stock quoted on NASDAQ as of 4:00 P.M., New York time, on each

such Common Stock is not quoted on NASDAQ, the average of the highest bid and
lowest asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization shall be used in such calculation.

         (g) MARKET PRICE is defined, in cases where the Common Stock is not

recent issuance, or deemed issuance, of Common Stock to any person not employed

discount in respect of a minority interest, as determined in accordance with the
Valuation Procedure, and assuming full disclosure and understanding of all

Quotation Bureau, Incorporated.

         (j) VALUATION PROCEDURE shall mean, with respect to the determination
of the Market Value, a determination which shall be final and binding on the
Company and the Holder made (i) by agreement among the Company and the Holder
within 20 days following the event requiring such determination or (ii) in the
absence of such an agreement, by an Independent Financial Expert selected in
accordance with the further provisions of this definition. If required, an
Independent Financial Expert shall be selected within five days following the
expiration of the 20-day period referred to above, either by agreement among the
Company and the Holder or, in the absence of such agreement, by lot from a list
of four potential Independent Financial Experts remaining after the Company
nominates three, the Holder nominates three, and each side eliminates one
potential Independent Financial Expert. The Independent Financial Expert shall
be instructed by the Company and the Holder to make its determination within 20
days of its selection. The Company and the Holder shall equally share the fees
and expenses of the Independent Financial Expert. The Company shall, if
requested, provide the Independent Financial Expert with a customary
indemnification for its opinions and services.

         (k) WARRANT NUMBER is defined as the number of Warrant Shares; the

further provided herein.

         (l) WARRANT SHARES is defined as the shares of Common Stock issued or
issuable hereunder, referred to collectively.

     2. GRANT. The Company, for value received, hereby grants to Holder, under
the terms herein, the right to purchase One Hundred Twenty-Five Thousand
(125,000) of the fully paid and non-assessable shares of the Company's
authorized but unissued Common Stock, subject to adjustment from time-to-time as
set out below.

     3. INVESTMENT AGREEMENT. This Warrant has been issued under the terms of
the Investment Agreement. The Holder is entitled to the benefits of the

thereto for a description of the rights and remedies thereunder.

     4. TERM. The right to exercise this Warrant shall expire five (5) years
after the date hereof.

     5. EXERCISE PRICE. The exercise price of this Warrant (the "Exercise
Price") shall be $11.21 per share, subject to adjustment from time to time as
set out below.

     6. ANTI-DILUTION AND OTHER ADJUSTMENTS.

         (a) ISSUANCE OF ADDITIONAL STOCK; INCREASE IN WARRANT NUMBER; DECREASE
IN EXERCISE PRICE; EXCEPTIONS. If the Company at any time after the date hereof
and prior to the

                                       3
<PAGE>

exercise or expiration of this Warrant shall issue or be deemed to have issued
any Additional Stock for a per-share consideration less than the Market Price
determined immediately prior to such issuance or deemed issuance, the Warrant
Number after such issuance shall increase to equal the number determined by
multiplying the Warrant Number in effect immediately prior to such issuance by a
fraction, (i) the numerator of which shall be the number of shares of Common
Stock issued and outstanding (or deemed issued) on a Fully Diluted Basis
immediately after such issuance, and (ii) the denominator of which shall be the
number of shares of Common Stock issued and outstanding (or deemed issued) on a
Fully Diluted Basis immediately prior to such issuance plus the number of shares
of Common Stock which the aggregate consideration received by the Company for
such Additional Stock would purchase at the Market Price immediately prior to
such issuance. Whenever from time-to-time the Warrant Number shall increase as
provided above, the Exercise Price shall correspondingly decrease to equal the
price determined by multiplying the Exercise Price in effect immediately prior
to the event giving rise to such increase, by a fraction (x) the numerator of
which shall be the Warrant Number in effect immediately prior to the increase,
and (y) the denominator of which shall be the Warrant Number as so increased.
NOTWITHSTANDING THE FOREGOING, HOWEVER, no change in the Warrant Number or
Exercise Price shall be made pursuant to this subparagraph (a) upon any issuance
or deemed issuance of Additional Stock (xx) if and to the extent registered on
Form S-8 or any successor form specified with respect to employee benefit plans
(as defined in Rule 405 implemented under the Securities Act) pursuant to the
Securities Act; (yy) consisting of the issuance of Common Stock or securities
convertible into Common Stock, on a date when such stock is Publicly Traded, in
a non-public offering for a per-share consideration equal to or exceeding 90% of
the Market Price, or (zz) consisting of the issuance of Common Stock in a public
offering pursuant to a firm underwriting wherein the gross proceeds exceed
Twenty-five Million Dollars ($25,000,000) and the per-share consideration equals
or exceeds 90% of the Market Price.

         (b) OPTIONS AND WARRANTS. If the Company shall at any time after the
date hereof other than pursuant to this Warrant issue or grant any options or
rights to subscribe for or to purchase Common Stock, all shares of Common Stock
which the holders of such options or rights shall be entitled to subscribe for
or to purchase thereunder shall be deemed to be issued as of the date of the
issuing or granting of such options or rights; and the minimum aggregate
consideration specified in such options or rights for the shares covered
thereby, plus the cash consideration, if any, received by the Company for the
issuance of such options or rights, shall be deemed to be the consideration
actually received by the Company for the issuance of such shares; after any
adjustment to the Warrant Number and Exercise Price upon the issuance of such
options or rights, and except as may be provided in subparagraph (m) below, no
further adjustments to the Warrant Number shall be made upon the actual issuance
of Common Stock upon exercise of such options or rights.

         (c) CONVERTIBLE SECURITIES. If the Company shall at any time after the
date hereof other than pursuant to this Warrant issue any stock or obligations
directly or indirectly convertible into or exchangeable for Common Stock, then
such issuance shall be deemed to be an issuance (as of the date of issue of such
stock or obligations) of the total maximum number of shares of Common Stock
necessary to effect the exchange or conversion of all such stock or obligations.
The amount received or receivable by the Company in consideration for the
issuance of such stock or obligations (deducting therefrom any commissions or
expenses paid or

                                       4
<PAGE>

incurred by the Company for any underwriting of, or otherwise in connection
with, such issuance), plus the minimum aggregate amount of premiums, if any,
payable to the Company upon exchange or conversion, shall be deemed to be the
consideration actually received by the Company for such Common Stock; after any
adjustment to the Warrant Number and Exercise Price upon the issuance of such
stock or obligations, and except as may be provided in subparagraph (m) below,
no further adjustments to the Warrant Number shall be made upon the actual
issuance of Common Stock upon the conversion or exchange of such stock or
obligations.

         (d) CALCULATION OF CONSIDERATION. In the case of an issuance of Common
Stock for cash, the consideration received by the Company therefor shall be
deemed to be the gross proceeds received for such shares; PROVIDED, HOWEVER,
that in any such case where the shares of Common Stock so issued are part of a
unit or combination of securities of the Company consisting of one or more
shares of Common Stock and other securities of the Company, if the amount of the
cash consideration received by the Company for the Stock so issued is not
determinable at the time of such issuance, such amount shall be deemed to be
such portion of the total cash consideration received by the Company for such
units or combinations as reasonably determined in good faith by the Company's
Board of Directors, regardless of the accounting treatment thereof by the
Company.

         (e) NON-CASH CONSIDERATION. In the case of an issuance (other than as a
dividend or other distribution on any Common Stock or upon conversion or
exchange of other securities of the Company) of shares of Additional Stock for a
consideration part or all of which shall be other than cash, the amount of such
consideration other than cash shall for purposes of this Warrant be the fair
market value of such consideration as reasonably determined in good faith by the
Company's Board of Directors regardless of the accounting treatment thereof by
the Company.

         (f) RESALE OF TREASURY STOCK. The sale or other disposition of any
shares of Common Stock of the Company or other securities held in the treasury
of the Company today, or of any securities resulting from any reclassification
or reclassifications of such shares or other securities which were effected
while they were held in the treasury of the Company, shall be deemed an issuance
thereof; PROVIDED, HOWEVER, that if any such share or other security is sold or
disposed of and subsequently re-acquired by the Company, no future sale or other
disposition thereof shall be deemed an issuance thereof.

         (g) STOCK SPLIT OR DIVIDEND. In case the shares of Common Stock at any
time outstanding shall be subdivided into a greater or combined into a lesser
number of shares of Common Stock, by stock-split, reverse split or otherwise, or
in case shares of Common Stock shall be issued as a stock dividend, the Warrant
Number shall be increased or decreased, as applicable, to an amount which shall
bear the same relation to the Warrant Number in effect immediately prior to such
subdivision, combination or stock dividend as the total number of shares of
Common Stock issued and outstanding (or deemed issued) immediately after such
subdivision, combination or stock dividend shall bear to the total number of
shares of Common Stock issued and outstanding (or deemed issued) immediately
prior to such subdivision, combination or stock dividend; likewise, in case of
such a subdivision, combination or stock dividend, the Exercise Price shall
correspondingly be increased or decreased, as applicable, to

                                       5
<PAGE>

the price which shall bear the same relation to the Exercise Price in effect
immediately prior to such subdivision, combination or stock dividend as the
total number of shares of Common Stock issued and outstanding (or deemed issued)
immediately prior to such subdivision, combination or stock dividend shall bear
to the total number of shares of Common Stock issued and outstanding (or deemed
issued) immediately after such subdivision, combination or stock dividend; an
adjustment pursuant to this subparagraph shall become effective immediately
after the effective date of such subdivision, combination or stock dividend,
retroactive to the record date (if any) for such subdivision, combination or
stock dividend.

         (h) ADJUSTMENT FOR INITIAL ERRORS. The Exercise Price specified in
paragraph 5 above was calculated as the average of the closing bid and asked
prices for the Common Stock on the NASDAQ-NMS over the fourteen (14) day period
ending immediately prior to the date of this Warrant. If for any reason it shall
hereafter be determined that such calculation was incorrect and the actual
average was different from the price specified in paragraph 5, then the Company
or the Holder (whichever shall discover such error) shall notify the other of
such determination and the Company shall forthwith reissue this Warrant, with an
appropriate change to the Exercise Price to be effective from the date hereof.

         (i) MERGER. In case of any capital reorganization, or any
reclassification of the Common Stock of the Company, or in case of any
consolidation of the Company with or the merger of the Company into any other
entity (other than a consolidation or merger in which the Company is the
surviving entity), this Warrant shall after such reorganization,
reclassification, consolidation or merger be exercisable upon the terms and
conditions specified herein, for the number of shares of stock or other
securities or property of the Company, or of the other entity resulting from
such consolidation or surviving such merger (as the case may be), which the
holder of this Warrant would have been entitled to receive, under the terms of
such reorganization, reclassification, consolidation or merger, if this Warrant
had been exercised in full prior to such reorganization, reclassification,
consolidation or merger. In any such case, if necessary, the provision set forth
in this Warrant with respect to the rights and interests thereafter of the
Holder shall be appropriately adjusted so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or property thereafter
deliverable on the exercise of this Warrant. The subdivision or combination of
shares of Common Stock at any time outstanding into a greater or lesser number
of shares of Common Stock shall not be deemed to be a reclassification of the
Common Stock of the Company for the purposes of this subparagraph. The Company
shall not effect any such consolidation or merger unless, prior to or
simultaneously with the consummation thereof, the surviving entity (if other
than the Company) resulting from such consolidation or merger shall assume, by
written agreement executed and delivered to the Company, the obligation to
deliver to the Holder such shares of stock, securities or assets to which in
accordance with the foregoing provisions, such Holder may be entitled, as well
as any other obligations arising under this Warrant.

         (j) ADJUSTMENTS TO NUMBERS OF OTHER SECURITIES. If as a result of any
provision of this paragraph 6 the Holder shall become entitled to acquire any
securities of the Company other than or in addition to Common Stock, the number
or amount of such other securities to which the Holder is entitled shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions applicable to the Warrant Number,
and the

                                       6
<PAGE>

provisions of this paragraph with respect thereto shall apply as nearly as may
be practicable to such other securities.

         (k) DE MINIMIS. Anything in this paragraph to the contrary
notwithstanding, no adjustment shall be made hereunder in any case where the
increase in the Warrant Number would be less than one (1) share of Common Stock;
but in such case any adjustment that would otherwise be made shall be delayed
and the adjustment shall be made only after the next issuance or deemed issuance
of Additional Stock which, together with any and all such issuances, shall
entitle Holder to receive at least one (1) whole additional share of such stock.
Any adjustments shall be made to the nearest full share.

         (l) CHANGES TO OPTIONS AND CONVERTIBLE SECURITIES. Upon any change to
the consideration specified in any option or right described in subparagraph
(b), above for the Common Stock issuable thereunder, or to the rate of
conversion or exchange specified in any stock or obligation described in
subparagraph (c) above, in any case where the issuance or grant thereof had
previously been the basis for an adjustment of the Warrant Number and Exercise
Price, the Warrant Number and Exercise Price then in effect shall forthwith be
readjusted to the Warrant Number and Exercise Price which would have been in
effect if the adjustments made upon the original issuance or grant thereof had
been made on the basis of such consideration or rate as so changed. Upon the
exercise of options or rights described in subparagraph (b) hereof, in any case
where the issuance or grant thereof had previously been the basis for an
adjustment of the Warrant Number and Exercise Price, if the actual aggregate
consideration received for the shares covered thereby is greater than the
minimum consideration which was deemed to have been received according to such
subparagraph, the Warrant Number and Exercise Price in effect at the time of
such exercise shall forthwith be readjusted to the Warrant Number and Exercise
Price which would have been in effect if the adjustment made upon the issuance
or grant thereof had been made on the basis of such consideration actually
received. Likewise, upon the conversion or exchange of stock or obligations
described in subparagraph (c), above, in any case where the issuance thereof had
previously been the basis for an adjustment of the Warrant Number and Exercise
Price, if the actual number of shares of Common Stock issued upon such
conversion or exchange shall be less than the maximum number deemed, according
to such subparagraph, to have been issued, or if the actual aggregate premium
paid to the Company upon such conversion or exchange shall be greater than the
minimum premium deemed (according to such subparagraph,) to have been paid, the
Warrant Number and Exercise Price in effect at the time of such conversion or
exchange shall forthwith be readjusted to the Warrant Number and Exercise Price
which would have been in effect if the adjustment on the original issuance
thereof had been made on the basis of the actual number of shares issued or, (as
the case may be) the actual premium paid.

         (m) EXPIRATION OF OPTIONS; RETIREMENT OF CONVERTIBLE SECURITIES. Upon
the termination, cancellation, expiration or lapse of options or rights
described in subparagraph (b) above in any case where the issuance or grant
thereof had previously been the basis for an adjustment of the Warrant Number
and Exercise Price, the Warrant Number and Exercise Price then in effect shall
forthwith be readjusted to the Warrant Number which would have been in effect if
the adjustments made upon the original issuance or grant of such options or
rights had excluded from the calculation of Common Stock issued and outstanding
(or deemed issued)

                                       7
<PAGE>

immediately after such issuance or grant, all Common Stock which the holders of
such expired or lapsed options or rights had been entitled to acquire
thereunder, and had excluded from the calculation of consideration deemed to
have been received by the Company, the consideration deemed by the terms of
sub-paragraph (b) to have been received for such expired or lapsed options or
warrants. Likewise, upon the retirement without conversion or exchange of
obligations described in subparagraph (c) above in any case where the issuance
thereof had previously been the basis for an adjustment of the Warrant Number
and Exercise Price, the Warrant Number and Exercise Price then in effect shall
forthwith be readjusted to the Warrant Number and Exercise Price which would
have been in effect if the adjustments made upon the original issuance of such
obligations had excluded from the calculation of Common Stock issued and
outstanding (or deemed issued) immediately after such issuance, all Common Stock
which the holders of such retired obligations had been entitled to acquire
thereunder, and had excluded from the calculation of consideration deemed to
have been received by the Company, all consideration deemed, by the terms of
subparagraph (c), to have been received for such retired obligations.

     7. COVENANTS AS TO PAR VALUE, AUTHORITY, PREEMPTIVE RIGHTS AND CHARGES. If
at any time the per share exercise price of this Warrant shall be less than the
par value of one share of Common Stock, the Company shall take such action as
shall be reasonably necessary to reduce such par value to an amount less than
the per share exercise price of this Warrant. The Company shall take such action
as shall be necessary to maintain the authority to issue validly, upon exercise
hereof according to the terms herein, and shall cause such Warrant Shares, upon
payment of the Exercise Price, to be fully paid, free of preemptive rights and
free from all transfer taxes, liens, security interests and charges with respect
to the issuance thereof.

     8. NOTICE OF STOCK SALES AND OTHER ADJUSTMENTS. Whenever there is an
issuance or sale of Additional Stock, the Company shall promptly place on file
at the Company's principal office a certificate signed by its Chief Financial
Officer stating the per-share price applicable to the transaction, a detailed
calculation of such price, the number of shares of Common Stock sold or issued,
the consideration received, and all fees and expenses incurred, and further
describing the transaction in detail and the adjustments (if any) to the Warrant
Number and Exercise Price resulting therefrom; and cause a copy of such
certificate to be sent to the Holder. Whenever the Warrant Number and Exercise
Price shall otherwise change, the Company shall promptly notify the Holder in
writing of such change and deliver to Holder a statement setting forth the
Warrant Number and Exercise Price after such adjustment(s), and a brief
statement of the facts requiring such adjustment(s) and the computation by which
such adjustment(s) was made.

     9. EXERCISE PROCEDURES.

         (a) UNCONDITIONAL SUBSCRIPTION. This Warrant may be exercised by
presenting it and tendering the aggregate Exercise Price in legal tender or by
bank's, cashier's or certified check to the Company at its address specified in
the Investment Agreement, along with written subscription substantially in the
form of EXHIBIT 9.00 hereof. In such case, the date on which this Warrant is
thus presented, accompanied by tender or payment as hereinbefore or hereinafter
provided, shall be referred to herein as the EXERCISE DATE. The Company shall
forthwith at its

                                       8
<PAGE>

expense (including the payment of issue taxes), issue and deliver the proper
number of shares of Common Stock, and such shares shall be deemed validly issued
for all purposes as of the opening of business on the Exercise Date, regardless
of any delay in the actual issuance.

         (b) CONDITIONAL EXERCISE. This Warrant may also be exercised
conditionally in contemplation of the future consummation of one or more
transactions, by presenting it and tendering the aggregate Exercise Price in the
manner specified in subparagraph (a) above, along with a notice clearly stating
the conditional nature of the exercise, specifying the conditions precedent to
the exercise in reasonable detail and the date after which the exercise shall be
deemed withdrawn if such conditions remain unsatisfied, and otherwise containing
the information called for in EXHIBIT 9.00. Any such condition precedent must be
unambiguous in its terms and as to its satisfaction. If the Company reasonably
determines that any condition precedent is ambiguous, it shall so notify the
Holder and such conditional exercise shall be of no force or effect until
clarified in writing by the Holder to the reasonable satisfaction of the
Company. Upon presentment, tender and notice in compliance with the foregoing
provisions, if the specified conditions are satisfied within the specified
period without prior revocation of the exercise by Holder, the Company shall
forthwith issue and deliver the proper number of shares of Common Stock in the
manner described above. In such case, the date on which the last remaining
condition was met shall be referred to herein as the Exercise Date, and such
shares shall be deemed validly issued for all purposes as of the opening of
business on such Exercise Date, regardless of any delay in the actual issuance.
If, on the other hand, after any such presentment, tender and notice, any
condition is unsatisfied on the specified date, or if the Holder revokes such
exercise in writing prior to the satisfaction of all conditions, the Company
shall forthwith return this Warrant and the Exercise Price to the Holder, and
this Warrant shall be deemed not to have been exercised.

     10. EXCHANGE OF SHARES FOR EXERCISE PRICE. The Holder at its option may
provide the Exercise Price under this Warrant by reducing the number of shares
for which the Warrant is otherwise exercisable by the number of shares having an
aggregate Market Price equal to the aggregate Exercise Price. In such a case,
tender of the Exercise Price shall be effected by Holder's written notice to the
Company of such reduction.

     11. SALE OR EXCHANGE OF COMPANY OR ASSETS. If prior to the exercise in full
hereof, the Company sells or exchanges all or substantially all of its assets to
an unaffiliated third party, or all or substantially all the outstanding Common
Stock is sold or exchanged to an unaffiliated third party, then the Holder at
its option may receive upon exercise hereof, in lieu of the Warrant Shares, such
money or property it would have been entitled to receive if this Warrant had
been exercised in full prior to such sale or exchange.

     12. RESALE OF WARRANT OR WARRANT SHARES. Neither this Warrant nor the
Warrant Shares have been registered under the SECURITIES ACT, or under the
securities laws of any state. Neither this Warrant nor any Warrant Shares may be
sold, transferred, pledged or hypothecated in the absence of (i) an effective
registration statement for this Warrant or the Warrant Shares, as the case may
be, under the SECURITIES ACT as amended and such registration or qualification
as may be necessary under the securities laws of any state that are applicable,
or (ii) an opinion of

                                       9
<PAGE>

counsel reasonably satisfactory to the Company that such registration or
qualification is not required. The Company shall cause a certificate or
certificates evidencing all or any of the Warrant Shares issued to bear
substantially the following legend:

              The shares evidenced by this certificate have not been
              registered under the SECURITIES ACT OF 1933 as amended
              (the "Act"), or under the securities laws of any state.
               The shares may not be sold, offered for sale, transferred,
              pledged or hypothecated in the absence of an effective
              registration statement under the ACT, and such registration
              or qualification as may be necessary under the securities
              laws of any state that are applicable, or an opinion of
              counsel satisfactory to the Company that such registration
              or qualification is not required.

     13. TRANSFER; RESTRICTIONS ON TRANSFER. This Warrant shall be registered on
the books of the Company which shall be kept at its principal office for that
purpose, and shall be transferable in whole or in part but only on such books by
the Holder in person or by duly authorized attorney with written notice
substantially in the form of EXHIBIT 13.00 hereto, only in compliance with the
preceding paragraph, and only in compliance with certain transfer restrictions
set out in the Agreement. The Company may issue appropriate stop orders to its
transfer agent to prevent a transfer in violation of such restrictions or the
preceding paragraph.

     14. CLOSING OF BOOKS. The Company shall not close its transfer books
against the transfer of this Warrant or any Common Stock or other securities
issuable upon the exercise of this Warrant in any manner which interferes with
the exercise of this Warrant, except if required to comply with any applicable
federal or state securities laws.

     15. REPLACEMENT OF WARRANT. At the request of the Holder and on production
of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and (in the case of loss, theft, or
destruction) if required by the Company, upon delivery of an indemnity agreement
with surety in such reasonable amount as the Company may determine thereof, the
Company at its expense will issue in lieu thereof a new Warrant of like tenor.

     16. INVESTMENT COVENANT. The Holder by its acceptance hereof covenants the
Holder is an "accredited investor" as defined in Rule 501(a) of the Securities
Act and that this Warrant is, and any stock issued hereunder will be, acquired
for investment purposes only and not for purposes of distribution, and that the
Holder will not distribute the same in violation of any state or federal law or
regulation.

     17. NOTICE. Any notice or other communication required by this Warrant to
be given to the Holder shall be provided according to the notice provisions in
the Investment Agreement.

     18. WAIVER OF JURY TRIAL. THE COMPANY WAIVES ALL RIGHT TO TRIAL BY JURY OF
ALL CLAIMS, DEFENSES, COUNTERCLAIMS AND SUITS OF ANY KIND

                                       10
<PAGE>

DIRECTLY OR INDIRECTLY ARISING FROM OR RELATING TO THIS WARRANT OR THE DEALINGS
OF THE PARTIES IN RESPECT HERETO. THE COMPANY ACKNOWLEDGES AND AGREES THAT THIS
PROVISION IS A MATERIAL TERM OF THIS WARRANT AND THAT THE HOLDER WOULD NOT
EXTEND ANY FUNDS UNDER THE LOAN DOCUMENTS IF THIS WAIVER OF JURY TRIAL WERE NOT
A PART OF THIS WARRANT. THE COMPANY ACKNOWLEDGES THAT THIS IS A WAIVER OF A
LEGAL RIGHT AND THAT IT MAKES THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER
CONSULTATION WITH, OR THE OPPORTUNITY TO CONSULT WITH, COUNSEL OF ITS CHOICE.
THE COMPANY AGREES THAT ALL SUCH CLAIMS, DEFENSES, COUNTERCLAIMS AND SUITS SHALL
BE TRIED BEFORE A JUDGE OF A COURT OF COMPETENT JURISDICTION, WITHOUT A JURY.

nominates three, the Holder nominates three, and each side eliminates one
potential Independent Financial Expert. The Independent Financial Expert shall
be instructed by the Company and the Holder to make its determination within 20
days of its selection. The Company and the Holder shall equally share the fees

set out below.

     3. INVESTMENT AGREEMENT. This Warrant has been issued under the terms of

set out below.

     6. ANTI-DILUTION AND OTHER ADJUSTMENTS.

         (a) ISSUANCE OF ADDITIONAL STOCK; INCREASE IN WARRANT NUMBER; DECREASE
IN EXERCISE PRICE; EXCEPTIONS. If the Company at any time after the date hereof
and prior to the

                                       3
<PAGE>

exercise or expiration of this Warrant shall issue or be deemed to have issued
any Additional Stock for a per-share consideration less than the Market Price
determined immediately prior to such issuance or deemed issuance, the Warrant
Number after such issuance shall increase to equal the number determined by
multiplying the Warrant Number in effect immediately prior to such issuance by a
fraction, (i) the numerator of which shall be the number of shares of Common
Stock issued and outstanding (or deemed issued) on a Fully Diluted Basis
immediately after such issuance, and (ii) the denominator of which shall be the
number of shares of Common Stock issued and outstanding (or deemed issued) on a
Fully Diluted Basis immediately prior to such issuance plus the number of shares
of Common Stock which the aggregate consideration received by the Company for
such Additional Stock would purchase at the Market Price immediately prior to
such issuance. Whenever from time-to-time the Warrant Number shall increase as
provided above, the Exercise Price shall correspondingly decrease to equal the
price determined by multiplying the Exercise Price in effect immediately prior
to the event giving rise to such increase, by a fraction (x) the numerator of
which shall be the Warrant Number in effect immediately prior to the increase,
and (y) the denominator of which shall be the Warrant Number as so increased.
NOTWITHSTANDING THE FOREGOING, HOWEVER, no change in the Warrant Number or
Exercise Price shall be made pursuant to this subparagraph (a) upon any issuance
or deemed issuance of Additional Stock (xx) if and to the extent registered on
Form S-8 or any successor form specified with respect to employee benefit plans
(as defined in Rule 405 implemented under the Securities Act) pursuant to the
Securities Act; (yy) consisting of the issuance of Common Stock or securities
convertible into Common Stock, on a date when such stock is Publicly Traded, in
a non-public offering for a per-share consideration equal to or exceeding 90% of
the Market Price, or (zz) consisting of the issuance of Common Stock in a public
offering pursuant to a firm underwriting wherein the gross proceeds exceed
Twenty-five Million Dollars ($25,000,000) and the per-share consideration equals
or exceeds 90% of the Market Price.

         (b) OPTIONS AND WARRANTS. If the Company shall at any time after the
date hereof other than pursuant to this Warrant issue or grant any options or
rights to subscribe for or to purchase Common Stock, all shares of Common Stock
which the holders of such options or rights shall be entitled to subscribe for
or to purchase thereunder shall be deemed to be issued as of the date of the
issuing or granting of such options or rights; and the minimum aggregate
consideration specified in such options or rights for the shares covered
thereby, plus the cash consideration, if any, received by the Company for the
issuance of such options or rights, shall be deemed to be the consideration
actually received by the Company for the issuance of such shares; after any
adjustment to the Warrant Number and Exercise Price upon the issuance of such
options or rights, and except as may be provided in subparagraph (m) below, no
further adjustments to the Warrant Number shall be made upon the actual issuance
of Common Stock upon exercise of such options or rights.

         (c) CONVERTIBLE SECURITIES. If the Company shall at any time after the
date hereof other than pursuant to this Warrant issue any stock or obligations
directly or indirectly convertible into or exchangeable for Common Stock, then
such issuance shall be deemed to be an issuance (as of the date of issue of such
stock or obligations) of the total maximum number of shares of Common Stock
necessary to effect the exchange or conversion of all such stock or obligations.
The amount received or receivable by the Company in consideration for the
issuance of such stock or obligations (deducting therefrom any commissions or
expenses paid or

                                       4
<PAGE>

incurred by the Company for any underwriting of, or otherwise in connection
with, such issuance), plus the minimum aggregate amount of premiums, if any,
payable to the Company upon exchange or conversion, shall be deemed to be the
consideration actually received by the Company for such Common Stock; after any
adjustment to the Warrant Number and Exercise Price upon the issuance of such
stock or obligations, and except as may be provided in subparagraph (m) below,
no further adjustments to the Warrant Number shall be made upon the actual
issuance of Common Stock upon the conversion or exchange of such stock or
obligations.

         (d) CALCULATION OF CONSIDERATION. In the case of an issuance of Common
Stock for cash, the consideration received by the Company therefor shall be
deemed to be the gross proceeds received for such shares; PROVIDED, HOWEVER,
that in any such case where the shares of Common Stock so issued are part of a
unit or combination of securities of the Company consisting of one or more
shares of Common Stock and other securities of the Company, if the amount of the
cash consideration received by the Company for the Stock so issued is not
determinable at the time of such issuance, such amount shall be deemed to be
such portion of the total cash consideration received by the Company for such
units or combinations as reasonably determined in good faith by the Company's
Board of Directors, regardless of the accounting treatment thereof by the
Company.

         (e) NON-CASH CONSIDERATION. In the case of an issuance (other than as a
dividend or other distribution on any Common Stock or upon conversion or
exchange of other securities of the Company) of shares of Additional Stock for a
consideration part or all of which shall be other than cash, the amount of such
consideration other than cash shall for purposes of this Warrant be the fair
market value of such consideration as reasonably determined in good faith by the
Company's Board of Directors regardless of the accounting treatment thereof by
the Company.

         (f) RESALE OF TREASURY STOCK. The sale or other disposition of any
shares of Common Stock of the Company or other securities held in the treasury
of the Company today, or of any securities resulting from any reclassification
or reclassifications of such shares or other securities which were effected
while they were held in the treasury of the Company, shall be deemed an issuance
thereof; PROVIDED, HOWEVER, that if any such share or other security is sold or
disposed of and subsequently re-acquired by the Company, no future sale or other
disposition thereof shall be deemed an issuance thereof.

         (g) STOCK SPLIT OR DIVIDEND. In case the shares of Common Stock at any
time outstanding shall be subdivided into a greater or combined into a lesser
number of shares of Common Stock, by stock-split, reverse split or otherwise, or
in case shares of Common Stock shall be issued as a stock dividend, the Warrant
Number shall be increased or decreased, as applicable, to an amount which shall
bear the same relation to the Warrant Number in effect immediately prior to such
subdivision, combination or stock dividend as the total number of shares of
Common Stock issued and outstanding (or deemed issued) immediately after such
subdivision, combination or stock dividend shall bear to the total number of
shares of Common Stock issued and outstanding (or deemed issued) immediately
prior to such subdivision, combination or stock dividend; likewise, in case of
such a subdivision, combination or stock dividend, the Exercise Price shall
correspondingly be increased or decreased, as applicable, to

                                       5
<PAGE>

the price which shall bear the same relation to the Exercise Price in effect
immediately prior to such subdivision, combination or stock dividend as the
total number of shares of Common Stock issued and outstanding (or deemed issued)
immediately prior to such subdivision, combination or stock dividend shall bear
to the total number of shares of Common Stock issued and outstanding (or deemed
issued) immediately after such subdivision, combination or stock dividend; an
adjustment pursuant to this subparagraph shall become effective immediately
after the effective date of such subdivision, combination or stock dividend,
retroactive to the record date (if any) for such subdivision, combination or
stock dividend.

         (h) ADJUSTMENT FOR INITIAL ERRORS. The Exercise Price specified in
paragraph 5 above was calculated as the average of the closing bid and asked
prices for the Common Stock on the NASDAQ-NMS over the fourteen (14) day period
ending immediately prior to the date of this Warrant. If for any reason it shall
hereafter be determined that such calculation was incorrect and the actual
average was different from the price specified in paragraph 5, then the Company
or the Holder (whichever shall discover such error) shall notify the other of
such determination and the Company shall forthwith reissue this Warrant, with an
appropriate change to the Exercise Price to be effective from the date hereof.

         (i) MERGER. In case of any capital reorganization, or any
reclassification of the Common Stock of the Company, or in case of any
consolidation of the Company with or the merger of the Company into any other
entity (other than a consolidation or merger in which the Company is the
surviving entity), this Warrant shall after such reorganization,
reclassification, consolidation or merger be exercisable upon the terms and
conditions specified herein, for the number of shares of stock or other
securities or property of the Company, or of the other entity resulting from
such consolidation or surviving such merger (as the case may be), which the
holder of this Warrant would have been entitled to receive, under the terms of
such reorganization, reclassification, consolidation or merger, if this Warrant
had been exercised in full prior to such reorganization, reclassification,
consolidation or merger. In any such case, if necessary, the provision set forth
in this Warrant with respect to the rights and interests thereafter of the
Holder shall be appropriately adjusted so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or property thereafter
deliverable on the exercise of this Warrant. The subdivision or combination of
shares of Common Stock at any time outstanding into a greater or lesser number
of shares of Common Stock shall not be deemed to be a reclassification of the
Common Stock of the Company for the purposes of this subparagraph. The Company
shall not effect any such consolidation or merger unless, prior to or
simultaneously with the consummation thereof, the surviving entity (if other
than the Company) resulting from such consolidation or merger shall assume, by
written agreement executed and delivered to the Company, the obligation to
deliver to the Holder such shares of stock, securities or assets to which in
accordance with the foregoing provisions, such Holder may be entitled, as well
as any other obligations arising under this Warrant.

         (j) ADJUSTMENTS TO NUMBERS OF OTHER SECURITIES. If as a result of any
provision of this paragraph 6 the Holder shall become entitled to acquire any
securities of the Company other than or in addition to Common Stock, the number
or amount of such other securities to which the Holder is entitled shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions applicable to the Warrant Number,
and the

                                       6
<PAGE>

provisions of this paragraph with respect thereto shall apply as nearly as may
be practicable to such other securities.

         (k) DE MINIMIS. Anything in this paragraph to the contrary
notwithstanding, no adjustment shall be made hereunder in any case where the
increase in the Warrant Number would be less than one (1) share of Common Stock;
but in such case any adjustment that would otherwise be made shall be delayed
and the adjustment shall be made only after the next issuance or deemed issuance
of Additional Stock which, together with any and all such issuances, shall
entitle Holder to receive at least one (1) whole additional share of such stock.
Any adjustments shall be made to the nearest full share.

         (l) CHANGES TO OPTIONS AND CONVERTIBLE SECURITIES. Upon any change to
the consideration specified in any option or right described in subparagraph
(b), above for the Common Stock issuable thereunder, or to the rate of
conversion or exchange specified in any stock or obligation described in
subparagraph (c) above, in any case where the issuance or grant thereof had
previously been the basis for an adjustment of the Warrant Number and Exercise
Price, the Warrant Number and Exercise Price then in effect shall forthwith be
readjusted to the Warrant Number and Exercise Price which would have been in
effect if the adjustments made upon the original issuance or grant thereof had
been made on the basis of such consideration or rate as so changed. Upon the
exercise of options or rights described in subparagraph (b) hereof, in any case
where the issuance or grant thereof had previously been the basis for an
adjustment of the Warrant Number and Exercise Price, if the actual aggregate
consideration received for the shares covered thereby is greater than the
minimum consideration which was deemed to have been received according to such
subparagraph, the Warrant Number and Exercise Price in effect at the time of
such exercise shall forthwith be readjusted to the Warrant Number and Exercise
Price which would have been in effect if the adjustment made upon the issuance
or grant thereof had been made on the basis of such consideration actually
received. Likewise, upon the conversion or exchange of stock or obligations
described in subparagraph (c), above, in any case where the issuance thereof had
previously been the basis for an adjustment of the Warrant Number and Exercise
Price, if the actual number of shares of Common Stock issued upon such
conversion or exchange shall be less than the maximum number deemed, according
to such subparagraph, to have been issued, or if the actual aggregate premium
paid to the Company upon such conversion or exchange shall be greater than the
minimum premium deemed (according to such subparagraph,) to have been paid, the
Warrant Number and Exercise Price in effect at the time of such conversion or
exchange shall forthwith be readjusted to the Warrant Number and Exercise Price
which would have been in effect if the adjustment on the original issuance
thereof had been made on the basis of the actual number of shares issued or, (as
the case may be) the actual premium paid.

         (m) EXPIRATION OF OPTIONS; RETIREMENT OF CONVERTIBLE SECURITIES. Upon
the termination, cancellation, expiration or lapse of options or rights
described in subparagraph (b) above in any case where the issuance or grant
thereof had previously been the basis for an adjustment of the Warrant Number
and Exercise Price, the Warrant Number and Exercise Price then in effect shall
forthwith be readjusted to the Warrant Number which would have been in effect if
the adjustments made upon the original issuance or grant of such options or
rights had excluded from the calculation of Common Stock issued and outstanding
(or deemed issued)

                                       7
<PAGE>

immediately after such issuance or grant, all Common Stock which the holders of
such expired or lapsed options or rights had been entitled to acquire
thereunder, and had excluded from the calculation of consideration deemed to
have been received by the Company, the consideration deemed by the terms of
sub-paragraph (b) to have been received for such expired or lapsed options or
warrants. Likewise, upon the retirement without conversion or exchange of
obligations described in subparagraph (c) above in any case where the issuance
thereof had previously been the basis for an adjustment of the Warrant Number
and Exercise Price, the Warrant Number and Exercise Price then in effect shall
forthwith be readjusted to the Warrant Number and Exercise Price which would
have been in effect if the adjustments made upon the original issuance of such
obligations had excluded from the calculation of Common Stock issued and
outstanding (or deemed issued) immediately after such issuance, all Common Stock
which the holders of such retired obligations had been entitled to acquire
thereunder, and had excluded from the calculation of consideration deemed to
have been received by the Company, all consideration deemed, by the terms of
subparagraph (c), to have been received for such retired obligations.

     7. COVENANTS AS TO PAR VALUE, AUTHORITY, PREEMPTIVE RIGHTS AND CHARGES. If
at any time the per share exercise price of this Warrant shall be less than the
par value of one share of Common Stock, the Company shall take such action as
shall be reasonably necessary to reduce such par value to an amount less than
the per share exercise price of this Warrant. The Company shall take such action
as shall be necessary to maintain the authority to issue validly, upon exercise
hereof according to the terms herein, and shall cause such Warrant Shares, upon
payment of the Exercise Price, to be fully paid, free of preemptive rights and
free from all transfer taxes, liens, security interests and charges with respect
to the issuance thereof.

     8. NOTICE OF STOCK SALES AND OTHER ADJUSTMENTS. Whenever there is an
issuance or sale of Additional Stock, the Company shall promptly place on file
at the Company's principal office a certificate signed by its Chief Financial
Officer stating the per-share price applicable to the transaction, a detailed
calculation of such price, the number of shares of Common Stock sold or issued,
the consideration received, and all fees and expenses incurred, and further
describing the transaction in detail and the adjustments (if any) to the Warrant
Number and Exercise Price resulting therefrom; and cause a copy of such
certificate to be sent to the Holder. Whenever the Warrant Number and Exercise
Price shall otherwise change, the Company shall promptly notify the Holder in
writing of such change and deliver to Holder a statement setting forth the
Warrant Number and Exercise Price after such adjustment(s), and a brief
statement of the facts requiring such adjustment(s) and the computation by which
such adjustment(s) was made.

     9. EXERCISE PROCEDURES.

         (a) UNCONDITIONAL SUBSCRIPTION. This Warrant may be exercised by
presenting it and tendering the aggregate Exercise Price in legal tender or by
bank's, cashier's or certified check to the Company at its address specified in
the Investment Agreement, along with written subscription substantially in the
form of EXHIBIT 9.00 hereof. In such case, the date on which this Warrant is
thus presented, accompanied by tender or payment as hereinbefore or hereinafter
provided, shall be referred to herein as the EXERCISE DATE. The Company shall
forthwith at its

                                       8
<PAGE>

expense (including the payment of issue taxes), issue and deliver the proper
number of shares of Common Stock, and such shares shall be deemed validly issued
for all purposes as of the opening of business on the Exercise Date, regardless
of any delay in the actual issuance.

         (b) CONDITIONAL EXERCISE. This Warrant may also be exercised
conditionally in contemplation of the future consummation of one or more
transactions, by presenting it and tendering the aggregate Exercise Price in the
manner specified in subparagraph (a) above, along with a notice clearly stating
the conditional nature of the exercise, specifying the conditions precedent to
the exercise in reasonable detail and the date after which the exercise shall be
deemed withdrawn if such conditions remain unsatisfied, and otherwise containing
the information called for in EXHIBIT 9.00. Any such condition precedent must be
unambiguous in its terms and as to its satisfaction. If the Company reasonably
determines that any condition precedent is ambiguous, it shall so notify the
Holder and such conditional exercise shall be of no force or effect until
clarified in writing by the Holder to the reasonable satisfaction of the
Company. Upon presentment, tender and notice in compliance with the foregoing
provisions, if the specified conditions are satisfied within the specified
period without prior revocation of the exercise by Holder, the Company shall
forthwith issue and deliver the proper number of shares of Common Stock in the
manner described above. In such case, the date on which the last remaining
condition was met shall be referred to herein as the Exercise Date, and such
shares shall be deemed validly issued for all purposes as of the opening of
business on such Exercise Date, regardless of any delay in the actual issuance.
If, on the other hand, after any such presentment, tender and notice, any
condition is unsatisfied on the specified date, or if the Holder revokes such
exercise in writing prior to the satisfaction of all conditions, the Company
shall forthwith return this Warrant and the Exercise Price to the Holder, and
this Warrant shall be deemed not to have been exercised.

     10. EXCHANGE OF SHARES FOR EXERCISE PRICE. The Holder at its option may
provide the Exercise Price under this Warrant by reducing the number of shares
for which the Warrant is otherwise exercisable by the number of shares having an
aggregate Market Price equal to the aggregate Exercise Price. In such a case,
tender of the Exercise Price shall be effected by Holder's written notice to the
Company of such reduction.

     11. SALE OR EXCHANGE OF COMPANY OR ASSETS. If prior to the exercise in full
hereof, the Company sells or exchanges all or substantially all of its assets to
an unaffiliated third party, or all or substantially all the outstanding Common
Stock is sold or exchanged to an unaffiliated third party, then the Holder at
its option may receive upon exercise hereof, in lieu of the Warrant Shares, such
money or property it would have been entitled to receive if this Warrant had
been exercised in full prior to such sale or exchange.

     12. RESALE OF WARRANT OR WARRANT SHARES. Neither this Warrant nor the
Warrant Shares have been registered under the SECURITIES ACT, or under the
securities laws of any state. Neither this Warrant nor any Warrant Shares may be
sold, transferred, pledged or hypothecated in the absence of (i) an effective
registration statement for this Warrant or the Warrant Shares, as the case may
be, under the SECURITIES ACT as amended and such registration or qualification
as may be necessary under the securities laws of any state that are applicable,
or (ii) an opinion of

                                       9
<PAGE>

counsel reasonably satisfactory to the Company that such registration or
qualification is not required. The Company shall cause a certificate or
certificates evidencing all or any of the Warrant Shares issued to bear
substantially the following legend:

              The shares evidenced by this certificate have not been
              registered under the SECURITIES ACT OF 1933 as amended
              (the "Act"), or under the securities laws of any state.
               The shares may not be sold, offered for sale, transferred,
              pledged or hypothecated in the absence of an effective
              registration statement under the ACT, and such registration
              or qualification as may be necessary under the securities
              laws of any state that are applicable, or an opinion of
              counsel satisfactory to the Company that such registration
              or qualification is not required.

     13. TRANSFER; RESTRICTIONS ON TRANSFER. This Warrant shall be registered on
the books of the Company which shall be kept at its principal office for that
purpose, and shall be transferable in whole or in part but only on such books by
the Holder in person or by duly authorized attorney with written notice
substantially in the form of EXHIBIT 13.00 hereto, only in compliance with the
preceding paragraph, and only in compliance with certain transfer restrictions
set out in the Agreement. The Company may issue appropriate stop orders to its
transfer agent to prevent a transfer in violation of such restrictions or the
preceding paragraph.

     14. CLOSING OF BOOKS. The Company shall not close its transfer books
against the transfer of this Warrant or any Common Stock or other securities
issuable upon the exercise of this Warrant in any manner which interferes with
the exercise of this Warrant, except if required to comply with any applicable
federal or state securities laws.

     15. REPLACEMENT OF WARRANT. At the request of the Holder and on production
of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and (in the case of loss, theft, or
destruction) if required by the Company, upon delivery of an indemnity agreement
with surety in such reasonable amount as the Company may determine thereof, the
Company at its expense will issue in lieu thereof a new Warrant of like tenor.

     16. INVESTMENT COVENANT. The Holder by its acceptance hereof covenants the
Holder is an "accredited investor" as defined in Rule 501(a) of the Securities
Act and that this Warrant is, and any stock issued hereunder will be, acquired
for investment purposes only and not for purposes of distribution, and that the
Holder will not distribute the same in violation of any state or federal law or
regulation.

     17. NOTICE. Any notice or other communication required by this Warrant to
be given to the Holder shall be provided according to the notice provisions in
the Investment Agreement.

     18. WAIVER OF JURY TRIAL. THE COMPANY WAIVES ALL RIGHT TO TRIAL BY JURY OF
ALL CLAIMS, DEFENSES, COUNTERCLAIMS AND SUITS OF ANY KIND

                                       10
<PAGE>

DIRECTLY OR INDIRECTLY ARISING FROM OR RELATING TO THIS WARRANT OR THE DEALINGS
OF THE PARTIES IN RESPECT HERETO. THE COMPANY ACKNOWLEDGES AND AGREES THAT THIS
PROVISION IS A MATERIAL TERM OF THIS WARRANT AND THAT THE HOLDER WOULD NOT
EXTEND ANY FUNDS UNDER THE LOAN DOCUMENTS IF THIS WAIVER OF JURY TRIAL WERE NOT
A PART OF THIS WARRANT. THE COMPANY ACKNOWLEDGES THAT THIS IS A WAIVER OF A
LEGAL RIGHT AND THAT IT MAKES THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER
CONSULTATION WITH, OR THE OPPORTUNITY TO CONSULT WITH, COUNSEL OF ITS CHOICE.
THE COMPANY AGREES THAT ALL SUCH CLAIMS, DEFENSES, COUNTERCLAIMS AND SUITS SHALL
BE TRIED BEFORE A JUDGE OF A COURT OF COMPETENT JURISDICTION, WITHOUT A JURY.
