except for shares of capital stock reserved for issuance in connection with the
transactions contemplated by this Agreement and the Ancillary Agreements, the
Company has not granted or issued, or agreed to grant or issue, any options,
warrants or similar rights to acquire or receive any of the authorized but

     5.3  NO DEFAULTS. Except as set forth in SCHEDULE 5.3, neither the Company

under, nor has there been any waiver given with respect to, any term or
provision of any charter, by-law, mortgage, indenture, agreement, instrument,
statute, rule, law, regulation, judgment, decree, order, writ, or injunction
applicable to it, such that such violations and defaults in the aggregate could
reasonably be expected to result in any material adverse change in the business,
assets, properties, condition (financial or otherwise) or results of operations
of the Company and its Subsidiaries, taken as a whole, or materially adversely
affect the ability of the Company to perform in any material respect its
obligations under this Agreement. All Regulatory Approvals required by the
Company and its Subsidiaries to conduct their respective business as now
conducted by them have been obtained and are in full force and effect, and the
Company and its Subsidiaries are in compliance with the terms and requirements
of such Regulatory Approvals. Except as set forth on SCHEDULE 5.3 hereto, since
December 31, 2002, none of the Company or any of its Subsidiaries has received
any written notice or other written communication from any Governmental Entity
regarding (i) any revocation, withdrawal, suspension, termination or
modification of, or the imposition of any material conditions with respect to,
any Regulatory Approval, (ii) any violation of any law by the Company or any of
its Subsidiaries, or (iii) any other limitations on the conduct of business by
the Company or any of its Subsidiaries.

     5.4  BURDENSOME AND CONFLICTING AGREEMENTS AND CHARTER PROVISIONS. Neither
the execution or delivery of the Transaction Documents by the Company, nor the
offering, issuance and sale of the Securities by the Company, nor fulfillment
of, or compliance with, the terms and provisions of the Transaction Documents,
nor the issuance by the Company of shares of Common Stock upon exercise of the
Common Stock Warrants, will, except as set forth in SCHEDULE 5.4, conflict with,
or result in a breach of the terms, conditions or provisions of, or constitute a
default under, or result in any violation of, or result in the creation of any
lien upon any of the properties or assets of the Company or any of its
Subsidiaries, or require any consent, approval or other action by, or notice to,
or filing with, any court or administrative or governmental body or any other
Person or pursuant to the Certificate of Incorporation or by-laws of the Company
or the certificate of incorporation or by-laws of any of the Company's
Subsidiaries, any award of any arbitrator or any material agreement (including

(the "ASSETS"). Except as set forth in SCHEDULE 5.5, none of the Assets is
subject to any encumbrances, except for minor liens that in the aggregate are
not substantial in amount, do not materially detract from the value of the
property or assets subject thereto or interfere with the present use thereof and

pending or threatened condemnation proceedings relating to any of the facilities
of the Company. The real property improvements (including leasehold
improvements) and fixtures and equipment of the Company are adequately insured
and are structurally sound with no known material defects. The facilities,
fixtures and equipment of the Company are in good operating condition and repair

Company's business as presently conducted and are in conformity in all material
respects with all applicable laws, ordinances, orders, regulations and other
requirements (including applicable zoning, environmental, motor vehicle safety
or standards, occupational safety and health laws and regulations) relating
thereto currently in effect, except where the failure to conform would not have
a material adverse effect on the business or financial condition of the Company.
The Assets are valued on the Company's books at or below actual cost less an
adequate and proper depreciation charge. The Company has not depreciated any of
the Assets on an accelerated basis or in any other manner inconsistent with
applicable Internal Revenue Service tax and fiscal guidelines, if any.

undisturbed possession of all leases material to them. All such leases are valid

agreement or understanding required to be described in or filed as an exhibit to
any Commission Documents that is not described in or filed as required by the
Securities Act or the Exchange Act, as the case may be. Except as set forth in
SCHEDULE 5.7, each such contract, agreement and understanding is valid and
binding and is in full force and effect and enforceable in accordance with its
terms (except as enforceability may be limited by applicable bankruptcy,
insolvency or similar laws affecting the enforcement of creditors' rights
generally or as may be limited by equitable principles relating to
enforceability), except in the case of such contracts, agreements or
understandings that are by their terms no longer in force or effect. Except as
set forth on SCHEDULE 5.7, (a) no approval or consent of, or notice to, any
Person is needed in order that such contract, agreement or understanding shall
continue in full force and effect in accordance with its terms without penalty,
acceleration or rights of early termination following the consummation of the
transactions contemplated by the Transaction Documents, other than such notices,
consents and approvals as have been obtained and (b) the Company and/or its
Subsidiaries are not in violation of, breach of, or default under any such
contract, agreement or understanding nor, to the Company's knowledge, is any
other party to any such contract, agreement or understanding.

<Page>

     All such financial statements (including any related schedules and notes)
have been prepared in accordance with generally accepted accounting principles
consistently applied, except to the extent set forth in the notes to such
financial statements. The balance sheets and the related schedules and notes
fairly present the financial condition of the Company and its consolidated
Subsidiaries as at the dates thereof and the net income and stockholders' equity
statements and the related schedules and notes fairly present the results of the
operations of the Company and its consolidated Subsidiaries for the periods
indicated. Except as set forth in SCHEDULE 5.8, the Company has incurred no
material liabilities since December 31, 2002, other than those incurred in the
ordinary course.

     Except as set forth in SCHEDULE 5.8, there has been no material adverse
change in the assets, business, prospects, properties, operations or condition,
financial or otherwise, of the Company and its Subsidiaries, taken as a whole,
since December 31, 2002.

     5.9  ACTIONS PENDING. There is no action, suit, investigation or proceeding
pending or, to the knowledge of the Company, threatened against the Company or
any of its Subsidiaries before any court, arbitrator or administrative or
governmental body that (a) seeks to enjoin or otherwise prevent the consummation
of the sale or issuance of the Securities or (b) materially and adversely
affects, or as to which there is a reasonable possibility of an adverse decision
that would materially and adversely affect, either individually or collectively,
the assets, business, properties, prospects, operations or condition, financial
or otherwise, of the Company and its Subsidiaries, taken as a whole. Neither the
Company nor any of its Subsidiaries is in violation of any judgment, order,
writ, injunction, decree, rule or regulation of any court or governmental
department, commission, board, bureau, agency or instrumentality, the violation
of which reasonably could be expected to, either individually or collectively,
materially and adversely affect the business, property, assets, prospects,
operations or condition (financial or otherwise) of the Company and its
Subsidiaries, taken as a whole.

     5.10 OFFERING OF SECURITIES. Assuming the accuracy of the representations
of Purchaser in this Agreement, the offer, sale and issuance of the Securities
are exempt from the registration requirements of the Securities Act. Neither the
Company nor any agent on its behalf has solicited or will solicit any offers to
sell or has offered to sell or will offer to sell all or any part of the
Securities to any Person so as to bring the offering and sale of such Securities
by the Company within the registration provisions of the Securities Act. The
Company has filed all notices and satisfied all registration or qualification
requirements of any state securities or Blue Sky law of any applicable
jurisdiction with respect to the offer, issuance and sale of the Securities or
required by the Ancillary Agreements.

     5.11 BROKER'S OR FINDER'S COMMISSIONS. Other than the fee payable to the
Placement Agent, no broker's or finder's or placement fee or commission will be
payable with respect to the sale or the issuance of the Securities contemplated
hereby or by the Ancillary Agreements as a result of any act or omission by the
Company, and the Company will hold Purchaser harmless from any claim, demand or
liability for broker's or finder's or placement fees or commissions alleged to
have been incurred in connection with the sale or the issuance of the Securities
due to any actions or omissions by the Company or its Subsidiaries or any of
their respective directors, officers or agents.

     5.12 APPLICATION OF PROCEEDS. The net proceeds of the sale of the Common

                                       12

     5.13 INTELLECTUAL PROPERTY.

     (a)  The Company and its Subsidiaries exclusively own or possess the
requisite licenses or rights (on reasonable commercial terms) to use all
patents, trade secrets, trademarks, service marks, service names, trade names,
copyrights and other intellectual property rights necessary to enable each of
them to conduct their respective businesses as now operated (collectively, the
"COMPANY IP"). SCHEDULE 5.13(a) sets forth a full and complete list of all
intellectual property rights of the Company and its Subsidiaries. There is no
claim or action by any Person pertaining to, or proceeding pending, or to the
Company's knowledge threatened, that challenges the rights of the Company or its
Subsidiaries with respect to any Company IP. To the Company's knowledge, neither
the Company's nor any of its Subsidiaries' current and intended products and
services infringe on any patents, licenses, trademarks, service marks, service
names, trade names, copyrights or other intellectual property rights held by any
Person and neither the Company nor any of its Subsidiaries is aware of any facts
or circumstances that might give rise to any of the foregoing.

     (b)  Except as set forth in SCHEDULE 5.13(b), no proceedings or claims in
which the Company alleges that any Person is infringing upon, or otherwise
violating, any Company IP are pending, and none has been served by, instituted
or asserted by the Company or any of its Subsidiaries, nor are any proceedings
threatened alleging any such violation or infringement.

     (c)  The Company has taken and will take all commercially reasonable
actions that are necessary or advisable in order to fully protect the Company
IP, in a manner consistent with prudent commercial practice.

     5.14 TAXES. The Company and each of its Subsidiaries has timely filed (or
caused to be filed) all Tax Returns that are required to be filed by (or with
respect to) it on or before the date hereof and has paid all Taxes due on or
before the date hereof whether or not reflected on such Tax Returns, including
pursuant to any assessment received by it. All such Tax Returns were true,
correct and complete in all material respects. None of such Tax Returns has been
audited by the relevant taxing authority, and no taxing authority has notified
(or threatened) the Company or any of its Subsidiaries, orally or in writing,
that such taxing authority will or may audit any such return. The Company and
its Subsidiaries have complied with all requirements of the Code, the Treasury
Regulations and any state, local or foreign law relating to the payment and
withholding of Taxes relating to them, and the Company and each of its
Subsidiaries have, within the time and in the manner prescribed by applicable
law, paid over to the proper taxing authorities all amounts required to be so
withheld and paid over relating to them. The charges, accruals and reserves on
the books of the Company and its Subsidiaries in respect of Taxes or other
governmental charges are adequate to cover any liability of the Company and its
Subsidiaries for Taxes through the date hereof. There are no liens for Taxes
with respect to any asset of the Company or any of its Subsidiaries, except for
liens with respect to Taxes that are not yet due and payable. No taxing
authority in a jurisdiction where the Company or any of its Subsidiaries, as the
case may be, does not file tax returns has made a claim, assertion or threat
that the Company or any of its Subsidiaries is or may be subject to taxation in
such jurisdiction.

     5.15 INSURANCE. The Company maintains or is covered by valid policies of
workers' compensation insurance, product liability insurance, and insurance with
respect to its properties and business. The Company currently maintains in full
force insurance covering the respective risks of the Company and its
Subsidiaries of such types and in such amounts, with such deductibles and with
such insurance companies as are customary for other companies engaged in

                                       13
<Page>

similar lines of business. The Company currently maintains key man life
insurance for John Mitola in the amount of $5,000,000, which is and will remain
in full force and effect through December 31, 2005.

     5.16 COMMISSION DOCUMENTS. Except as set forth in SCHEDULE 5.16, the
Company has filed all registration statements, proxy statements, information
statements, reports and other documents required to be filed by it under the
Securities Act or the Exchange Act, and all amendments thereto (collectively,
the "COMMISSION DOCUMENTS"). Each Commission Document when filed with the
Commission was true and accurate in all material respects and in compliance in
all material respects with the requirements of its respective report form and
the rules and regulations of the Commission. No Commission Document contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
contained therein, in light of the circumstances under which made, not
misleading.

     5.17 DISCLOSURE. Neither this Agreement nor any other document, certificate
or statement prepared by or on behalf of the Company by its authorized
representatives or agents and furnished to or made available to the Purchaser in
writing by or on behalf of the Company by its authorized representatives or
agents in connection herewith, contains any untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary in
order to make the statements contained herein and therein, in the light of the
circumstances under which made, not misleading.

                                   ARTICLE VI
                        REPRESENTATIONS OF THE PURCHASER

     Purchaser represents and warrants as to itself only as follows:

     6.1  INVESTMENT PURPOSE. Purchaser is purchasing the Securities for
Purchaser's own account for investment only and not with a view toward or in
connection with the public sale or distribution thereof. Purchaser will not
resell the Securities except pursuant to sales that are exempt from the
registration requirements of the Securities Act and all applicable state
securities laws, and/or sales registered under the Securities Act and all
applicable state securities laws. Purchaser understands that Purchaser may bear
the economic risk of this investment indefinitely, unless the Securities are
registered pursuant to the Securities Act and any applicable state securities
laws or an exemption from such registration is available.

     6.2  ACCREDITED INVESTOR STATUS/ORGANIZATION. Purchaser is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D promulgated
under the Securities Act. By reason of its business and financial experience,
sophistication and knowledge, Purchaser is capable of evaluating the risks and
merits of the investment made pursuant to this Agreement. In addition, Purchaser
is a corporation duly organized and validly existing under the laws of the State
of Maryland and has total assets in excess of $5 million.

     6.3  AUTHORIZATION; ENFORCEMENT. This Agreement has been duly and validly
authorized, executed and delivered on behalf of Purchaser and is the legally
valid and binding agreement of Purchaser enforceable in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, or similar laws affecting the enforcement of

                                       14
<Page>

creditors' rights generally or by equitable principles relating to
enforceability. As of the Closing Date, each Ancillary Agreement to which
Purchaser is a party will be the legally valid and binding agreement of
Purchaser enforceable in accordance with its terms, except as enforceability may
be limited by applicable bankruptcy, insolvency, or similar laws affecting the
enforcement of creditors' rights generally or by equitable principles relating
to enforceability.

     6.4  BROKER'S OR FINDER'S COMMISSIONS. Other than the fee payable to the
Placement Agent (which will be paid by the Company) no broker's or finder's or
placement fee or commission will be payable with respect to the sale or the
issuance of the Securities as a result of any act or omission by the Purchaser,
and the Purchaser will hold the Company harmless from any claim, demand or
liability for broker's or finder's or placement fees or commissions alleged to
have been incurred in connection with the sale or the issuance of the Securities
due to any actions of the Purchaser.

                                   ARTICLE VII
                                 INDEMNIFICATION

     7.1  INDEMNIFICATION BY COMPANY. In addition to all other sums due
hereunder or provided for in this Agreement, the Company agrees to indemnify and
hold harmless Purchaser and its officers, directors, agents, employees and
partners (each, an "INDEMNIFIED PARTY") to the fullest extent permitted by law
from and against any and all losses, claims, damages, expenses (including
reasonable fees, disbursements and other charges of counsel), damages or other
liabilities ("LOSSES") resulting from:

          (i)  any breach of any representation or warranty, covenant or
     agreement of the Company in this Agreement, or

          (ii) any legal, administrative or other actions (including actions
     brought by any equityholders of the Company or derivative actions brought
     by any Person claiming through the Company or in the Company's name),
     proceedings or investigations (whether formal or informal), or written
     threats thereof, based upon, relating to or arising out of any of the
     Transaction Documents or the Securities, the transactions contemplated
     hereby or thereby, or any indemnified person's role therein;

PROVIDED, HOWEVER, that the Company shall not be liable under this SECTION 7.1:
(a) for any amount paid in settlement of claims without the Company's consent
(which consent shall not be unreasonably withheld or delayed) or (b) to the
extent that it is finally judicially determined that such Losses resulted
primarily from the willful misconduct, bad faith or gross negligence of such
indemnified party or a breach of such Purchaser's representations in ARTICLE VI;
PROVIDED, FURTHER, that if and to the extent that such indemnification is
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of such indemnified liability that shall be
permissible under applicable laws. In connection with the obligation of the
Company to indemnify for expenses as set forth above, the Company further agrees
to reimburse each indemnified party for all such expenses (including reasonable
fees, disbursements and other charges of counsel) as they are incurred by such
indemnified party; PROVIDED, HOWEVER, that in no event shall the Company be
required to pay fees and expenses under this ARTICLE VII for more than one firm
of attorneys in addition to the firm of attorneys representing the Company in
any jurisdiction in any one legal action or group of related legal

                                       15
<Page>

actions; PROVIDED, FURTHER, that if an indemnified party is reimbursed hereunder
for any expenses, such reimbursement of expenses shall be refunded to the extent
it is finally judicially determined that the Losses in question resulted
primarily from the willful misconduct, bad faith or gross negligence of such
indemnified party.

     7.2 INDEMNIFICATION FOR REGISTRATION. (a) In the event of a registration of
the Common Shares and the Common Stock evidenced by the Common Stock Warrants
under the Securities Act pursuant to SECTION 4.4 herein, the Company shall
indemnify and hold harmless, to the fullest extent permitted by law, the
Purchaser, its Affiliates, each of their respective officers, directors,
employees and agents, each underwriter of such Eligible Securities and each
other person, if any, who controls such Purchaser or underwriter within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which Purchaser, or any such Affiliate, or any
such officer, director, employee, agent, underwriter or controlling person, may
become subject under the Securities Act or otherwise or in any action in respect
thereof, and will reimburse each such person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action as such expenses are incurred,
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 Eligible Securities were registered under the Securities Act pursuant
to SECTION 4.4, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading;
PROVIDED, HOWEVER, that the Company shall not be liable to Purchaser, or any
such Affiliate, officer, director, employee, agent, underwriter or controlling
person, in any such case if and to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in conformity with
information furnished by Purchaser, or any such Affiliate, officer, director,
employee, agent, underwriter or controlling person, in writing specifically for
use in such registration statement or prospectus.

          (b)  Purchaser will indemnify and hold harmless the Company, each
underwriter and each person, if any, who controls the Company or any underwriter
within the meaning of the Securities Act, each officer of the Company who signs
the registration statement, each director of the Company, each other seller of
securities registered by the registration statement covering such Eligible
Securities and each person, if any, who controls such seller, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or any such officer, director, underwriter, other seller or controlling person
may become subject under the Securities Act or otherwise, and shall reimburse
the Company and each such officer, director, underwriter, other seller and
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action, insofar as such losses, claims, damages or liabilities (or
action in respect thereof) arise out of or are based upon an untrue statement or
alleged untrue statement of material fact, or omission or alleged omission of a
material fact required to be stated therein, made in reliance upon and in
conformity with information pertaining to Purchaser furnished in writing to the
Company by Purchaser specifically for use in the registration statement or
prospectus relating to such Eligible Securities. Notwithstanding the immediately
preceding sentence, the aggregate liability of Purchaser hereunder shall not in
any event exceed the net

                                       16
<Page>

proceeds received by Purchaser from the sale of Eligible Securities covered by
such registration statement.

          (c)  The reimbursements required by this SECTION 7.2 shall be made by
periodic payment during the course of the investigation or defense, as and when
bills are received and expenses incurred.

          (d)  The indemnification provided for under this SECTION 7.2 shall
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director, employee, agent, or
controlling person of such indemnified party and shall survive the transfer of
securities.

     7.3  NOTIFICATION. Each indemnified party under this ARTICLE VII shall,
promptly (and in any event within 20 days), after the receipt of notice of the
commencement of any action or other proceeding against such indemnified party in
respect of which indemnity may be sought from the Company under this ARTICLE
VII, notify the Company in writing of the commencement thereof. The failure of
any indemnified party so to notify the Company of any such action shall not
relieve the Company from any liability that it may have to such indemnified
party pursuant to this ARTICLE VII, except to the extent that such failure
causes material prejudice to the Company. In case any such action or other
proceeding shall be brought against any indemnified party and it shall notify
the Company of the commencement thereof, the Company shall be entitled to
participate therein and, to the extent that it may wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party;
PROVIDED, HOWEVER, that any indemnified party may, at its own expense, retain
separate counsel to participate in such defense. Notwithstanding the foregoing,
in any action or proceeding in which both the Company and an indemnified party
is, or is reasonably likely to become, a party, such indemnified party shall
have the right to employ separate counsel at the Company's expense and to
control its own defense of such action or proceeding if, in the reasonable
written opinion of counsel to such indemnified party (obtained at the expense of
the Company), (a) there are or may be legal defenses available to such
indemnified party or to other indemnified parties that are different from or
additional to those available to the Company or (b) any conflict or potential
conflict exists between the Company and such indemnified party that would make
such separate representation advisable; PROVIDED, HOWEVER, that in no event
shall the Company be required to pay fees and expenses under this ARTICLE VII
for more than one firm of attorneys in addition to the firm of attorneys
representing the Company in any jurisdiction in any one legal action or group of
related legal actions. The Company shall not, without the consent of the
indemnified party (which consent shall not be unreasonably withheld), consent to
the 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 to such claim or
litigation or that requires action other than the payment of money by the
Company. The rights accorded to indemnified parties hereunder shall be in
addition to any rights that any indemnified party may have at common law, by
separate agreement or otherwise.

     7.4  PAYMENT. No indemnifying party shall be liable for any amounts paid in
a settlement effected without the consent of such indemnifying party, which
consent shall not be unreasonably withheld or delayed. No indemnifying party
shall, without the indemnified party's prior written consent, consent to entry
of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the plaintiff to the indemnified party
of a release from all liability in respect of such claim or litigation.

     7.5  SURVIVAL OF PROVISIONS OF ARTICLE VII. The obligations of the Company
under this ARTICLE VII shall survive indefinitely.

against liability for the payment of, all reasonable out-of-pocket expenses
arising in connection with:

          (a)  the negotiation and execution of the Transaction Documents and
     the issuance of the Securities, including all taxes (including any
     intangible personal property tax, together in each case with interest and
     penalties, if any, and also including any filing fees payable to any
     governmental authority, and any income tax payable by any Purchaser in
     respect of any reimbursement for any such tax or fee) that may be payable
     in respect of the execution and delivery of the Transaction Documents or
     the issuance, delivery or acquisition (but not the holding, ownership or
     transfer) of any of the Securities issued pursuant to this Agreement or any
     Common Stock issuable upon exercise of the Common Stock Warrants;

          (b)  the reasonable fees and expenses of Purchaser's special counsel,
     if any, in connection with and any subsequent modification of the
     Transaction Documents or consent thereto (including any proposed
     modification or consent, whether or not finalized); and

          (c)  the cost and expenses, including reasonable attorney's fees,
     incurred by Purchaser in enforcing any of its rights hereunder, including,
     without limitation, costs and expenses incurred in any bankruptcy case.

The obligations of the Company under this SECTION 8.1 shall survive the transfer
of any Securities by Purchaser.

     8.2  RESTRICTIVE LEGENDS. The Securities shall bear a legend in
substantially the following form:
