ITEM 1. BUSINESS

OVERVIEW

     We are a leading facilities-based integrated communications service
provider to small and medium-sized business and communications carrier customers
in the Southwestern United States. We offer business customers an integrated
bundle of communications products and services including local exchange,
domestic and international long distance, enhanced voice, data, Internet and
dedicated private line services. Additionally, we offer our
communications-intensive and carrier customers dark fiber, high bandwidth
dedicated fiber infrastructure, terminating access for domestic and
international long distance and ATM, frame relay and IP data transport services.
We believe that our current and planned networks will provide our customer base
the most comprehensive service alternative when compared to the incumbent and
other competitive communications service providers in our region.

     Our communications services are provided over our scalable fiber, voice and
data networks which, upon completion, will connect nearly every primary,
secondary and tertiary market in the six-state region of Texas, Louisiana,
Arkansas, Oklahoma, New Mexico and Arizona. At year-end 1999, our inter-city
long-haul fiber network consisted primarily of 96 fiber strands covering
approximately 3,000 route miles, which we expect to expand to approximately
7,000 route miles by year-end 2000. Additionally, at year-end 1999, we provided
switch-based competitive local exchange services in ten markets, which we expect
to expand to approximately 48 markets by year-end 2000. At year-end 1999, we had
11 voice and 13 data switches


                                       1
<PAGE>   4


installed and operational on our network, which we expect to expand to 14 voice
and 17 data switches by year-end 2000.

     We introduced electronic bonding, which is the on-line and real-time
connections of our operations support systems with those of the ILECs, with
Southwestern Bell in Texas in the fourth quarter of 1999. We are determined to
achieve such bonding with the ILECs in most of our markets by the end of 2000.
This electronic interface allows us to create service requests on-line, leading
to faster installations of customer orders and a reduction in the number of
errors associated with multiple manual inputs. We expect electronic bonding to
improve productivity by decreasing the period between the time of sale and the
time the customer's line is installed on our network. We expect that electronic
bonding with Southwestern Bell, for example, will ultimately enable us to reduce
our provisioning times once orders are submitted from 25 business days to as few
as five business days. We also expect an automated process will reduce our
selling, general and administrative costs.

     We have begun, and will continue, to acquire and develop our back office
systems and procedures with vendors, including Metasolv, DSET, Sterling, Oracle,
RiverRock, Micromuse, RTS and Portal. We believe these platforms provide us with
a competitive advantage in terms of reducing costs, processing large order
volumes for multiple products and services, providing bundled bills and billing
options over the Internet and enhancing customer service. Our back office
systems enable us to enter, schedule and track a customer's order from the point
of sale to the installation and testing of service. These systems interface with
each other and include order entry, credit approval, provisioning, billing,
collection, customer service, trouble management, monitoring, facilities
inventory management and reporting systems.

     We are a Texas corporation. Our principal executive offices are located at
15601 Dallas Parkway, Suite 700, Dallas, Texas 75248, and our telephone number
is (972) 982-9500. We maintain a World Wide Web site at www.caprock.com. The
reference to our World Wide Web address does not constitute incorporation by
reference of the information contained at the site. In this Annual Report on

RECENT DEVELOPMENTS

     On March 21, 2000, we filed a registration statement on Form S-3 with the
Securities and Exchange Commission registering up to $900,000,000 of our debt
securities, preferred stock and/or common stock to be offered on a delayed or
continuous basis. As of the date hereof, the registration statement relating to
these securities has not yet become effective. No securities may be sold, nor
may offers to buy be accepted, prior to the time the registration statement
becomes effective, and an offering of any securities under such registration
statement will be made only by means of a prospectus supplement meeting the
requirements of Section 10 of the Securities Act of 1933.

     We may offer from time to time any combination of these securities in one
or more offerings, and certain of our shareholders may offer from time to time
shares of common stock. We will provide specific terms of these securities and
their offering prices in a prospectus supplement. No assurances can be made as
to when, or if, any offering will be completed and, if completed, as to the
amount of the offering or the type of securities offered. If an offering of
securities is completed, the net proceeds from such offering and our intended
use of such net proceeds will be set forth in a prospectus supplement for such
offering.

OUR FIBER, VOICE AND DATA NETWORKS

     Our communications services are provided over our scalable fiber, voice and
data networks, which upon completion will connect nearly every primary,
secondary and tertiary market in our six-state region. At year-end 1999, our
inter-city long-haul network covered approximately 3,000 route miles,


                                       2
<PAGE>   5


which we expect to expand to approximately 7,000 route miles by year-end 2000
and approximately 7,500 route miles by year-end 2001. Additionally, at year-end
1999, we provided competitive local exchange services in ten markets, which we
expect to expand to approximately 48 markets by year-end 2000. At year-end 1999,
we had 11 voice and 13 data switches installed and operational on our network,
which we expect to expand to 14 voice and 17 data switches by year-end 2000.

     Our network is designed to be sufficiently scalable and flexible to meet
future demand and to accommodate advances in fiber technology and electronics.
We are burying three to four conduits throughout our network. These conduits are
shared with our joint build partners, for those segments in our network we are
jointly building with others. In one of our conduits, we are installing a
minimum combination of 96 single mode and Lucent Truewave or comparable fibers.
We are retaining, at a minimum, at least one conduit for future use. Both
Truewave and single-mode fiber are capable of supporting Dense Wavelength
Division Multiplexing ("DWDM"). We intend to retain at least 24 fiber strands
throughout most of our network. The routes of the network are primarily
constructed on state highway and county road rights of way, and are planned to
be generally geographically diverse from the existing fiber networks of AT&T,
Sprint, and MCI WorldCom. We plan to interconnect our fiber network with the
fiber networks of selected Mexican carriers at multiple border crossings.

     We intend to have Class 5 switching functionality in all markets in which
we provide competitive local exchange services. We have two switches located in
each of Dallas and Houston, Texas as well as Phoenix, Arizona. We also have one
switch in each of San Antonio, Victoria and McAllen, Texas, Lafayette, Louisiana
and Oklahoma City, Oklahoma. We lease one switch in Jersey City, New Jersey. Our
regional network is controlled and monitored by a state of the art network
operations control center located in Dallas. Our network operations center in
Houston supports our Dallas network operations center, providing back up in the
event of a network failure. Locally based switch engineers and technicians also
manage each switch.

     We generally lease local network trunking facilities from the ILEC and/or
one or more competitive local exchange carriers ("CLECs") in order to connect
our switch to major ILEC central offices serving the central business district
and outlying areas of business concentrations. Our switch is also connected to
ILEC tandem switches and certain interexchange carrier points-of-presence. To
access the largest number of customers possible without having to lay fiber to
each of their premises, we locate access equipment such as integrated digital
loop carriers, digital subscriber line access multiplexers and related equipment
in each of the ILEC central offices.

     As each customer is signed up, we provide service by leasing unbundled
loops from the ILEC to connect our integrated digital loop carriers located in
the central office to the customer premise equipment. For large business,
government, or other institutional customers or for numerous customers located
in large buildings, it can be more cost-effective for us to lease ILEC or CLEC
capacity, or a wireless local loop from one of the emerging wireless CLECs, to
connect the customer to our network. In these cases, we will locate our
integrated digital loop carriers or other equipment in the customer's building.

     In order to provide comprehensive geographic service coverage to customers
with locations in areas beyond the reach of central offices where we have
established collocations, we generally provide services utilizing tariffs
commonly referred to as "UNE-P." These tariffs enable us to purchase multiple
unbundled network elements ("UNEs") from the ILEC, including the element that
packages all of the elements back together to provide local service dial tone
and advanced local features. The UNE-P platform tariff was mandated by the
Federal Communications Commission ("FCC") in their UNE Remand Order in October
1999 in order to accelerate local service competition in urban and rural
markets. The FCC has said it will review the Order again in three years.

     In addition to being lower in cost than total service resale, UNE-P mirrors
UNEs in treatment of access fees. With total service resale, the ILEC is capable
of charging and retaining originating and terminating access fees for long
distance calls. These fees are generally a few cents per minute on both the
originating and terminating ends. With UNEs and UNE-P, no originating fees are
charged to us by the ILEC. Additionally, with these tariffs we are able to
charge other long distance companies a terminating access fee for completing
their long distance call to our local service customer. By bundling long
distance together with local service provided over UNE and UNE-Ps, the economics
of long distance change dramatically and positively. By carrying end to end
traffic on our own network, the variable cost of carrying a long distance call
from one of our customers to another of our customers drops from several cents
per minute to a fraction of a cent per minute. These attractive economics will
position us to compete


                                       3
<PAGE>   6


profitably as competition in the long distance market opens up to the Regional
Bell Operating Companies ("RBOCs").

     To reduce the cost of fiber retained for our own use, we have sold in the
past, and intend to sell in the future, conduit and dark fiber to third parties.
In addition, we have strategically entered into several joint build fiber
arrangements, which will significantly reduce the construction costs of our
networks. To date, we have entered into joint build fiber arrangements with
Enron Communications, AT&T, 360networks Inc. (formerly Worldwide Fiber) and
Pathnet. The joint build arrangements provide several benefits, including
reduction of construction costs, accelerated acquisition of rights of way, and
the freeing up of resources to focus attention on the construction of other
portions of the network.

CAPROCK'S COMMUNICATIONS SERVICES

     We provide services to small and medium-sized businesses, communications
carrier customers and high-end, multi-line residential customers. Our business
customers are able to customize their selection of our services to fit their
needs. Integrated services offered to our business customers include local
exchange, domestic and international long distance, enhanced voice, data,
Internet and dedicated private line services.  Our principal carrier services
include dark fiber, high bandwidth dedicated fiber infrastructure, terminating
access for domestic and international long distance and ATM, frame relay and IP
data transport services. Systems services primarily represents equipment and
telecommunications services provided to off-shore and overseas oil and gas
companies. Systems services include our integrated services products as well as
customer premise equipment.

INTEGRATED SERVICES

     We offer integrated services, including local exchange, domestic and
international long distance, enhanced voice, data, Internet and dedicated
private line services, to our business customers.

     Local Exchange Services. We offer local telephone services, including local
dial tone and enhanced features such as:

     o    Call forwarding,
     o    Call waiting,
     o    Calling number identification and/or calling name identification,
     o    Call transfer,
     o    Distinctive ringing, and
     o    Station-to-station four digit dialing without a private branch
          exchange.

     By offering local dial tone service, we also receive originating and
terminating access charges for long distance calls placed or received by our
customers. We offer local voice services over unbundled loops as well as high
capacity lines such as T-1 connections. We also combine voice and data over T-1
connections, and soon, over DSL connections.

     Domestic and International Long Distance Services. We offer a broad range
of domestic and international long distance services, which include "1+"
outbound calling, inbound toll free service, as well as calling cards, debit
cards and operator assistance.

     Data Services. Many small and medium-sized businesses do not use data or
high speed Internet access services today. We believe that these businesses will
increasingly demand these services as e-commerce and other Internet products
develop. At year-end 1999, we had 11 voice and 13 data switches installed and
operational on our network, which we expect to expand to 14 voice and 17 data
switches by year-end 2000. This data network supports all of our data, DSL and
Internet services. We also believe that the value of a network is exponential to
the number of sites or customers connected. By concentrating our network
deployment on the Southwest, we believe we are building an advanced data network
that is very attractive to regional businesses.

     DSL and Other High Speed Data Services. We offer high speed Internet access
and data transmission services which support wide area network interconnections.
These services establish communications links


                                       4
<PAGE>   7


that enable file sharing among geographically distributed computer workgroups.
The services may be provided via ATM, frame relay or dedicated point-to-point
connections. To provide these services, we use leased last mile high capacity
connections, such as T-1s and DS-3s, to reach our customers and connect them to
our own long-haul fiber network or capacity leased from others. We intend to
provide DSL services throughout the Southwest region from 200 central offices
through resale or deployment of DSL infrastructure equipment.

     FlexT. We recently announced our FlexT bundled services package for
business customers. FlexT combines local, domestic and international long
distance, Internet and high speed data services via dedicated access, provides
efficient cost alternatives to traditional rate plans, and combines all services
on a single invoice.

CARRIER SERVICES

     We intend to establish ourself as the premier carriers' carrier within the
Southwest region, providing voice, data, broadband and dark fiber services over
the most extensive advanced fiber network in the Southwest region. Our principal
carriers' carrier products are domestic and international long distance
terminating access, bandwidth provision, calling cards, debit cards and dark
fiber. We have more than 150 carrier customers, including AT&T, MCI WorldCom,
Qwest and Sprint. For the year ended December 31, 1999, revenues from services
provided to MCI WorldCom and Enron each accounted for more than 10% of our
revenues.

     Domestic and International Long Distance Terminating Access. We offer
carrier customers the ability to terminate their long distance calls through our
voice switches. This is provided on a per-call basis, with rates generally based
on a per minute basis. We provide these services for both domestic and
international calls. Most of our carrier international traffic is terminated in
Mexico and in countries where we have established direct connections with
foreign government owned or competitive telephone companies.

     High Capacity Bandwidth. We offer high capacity bandwidth such as T-1,
DS-3, OC-3, OC-12 and OC-48 services to our carrier customers. This service is
generally provided over our own fiber network. Utilizing our DWDM electronics,
we have also begun to market individual wavelengths over our fiber network.
Customers purchasing wavelengths provide their own electronics at each end of
the fiber segment. Wavelengths enable them to adjust capacity as if they owned
their own fiber. Carriers utilize this broadband capacity to support their voice
and data traffic requirements and to establish diverse routing.

     Frame Relay and ATM. We provide end-to-end performance of a customer's
network throughout our region, including the local loop. We are able to extend
this level of performance since we have one of the most highly distributed frame
relay networks in the Southwest region, extending the self-healing benefits of
frame relay to most primary, secondary and tertiary markets through our region.
Our ATM services are designed for high capacity customers requiring the
flexibility of serving single or multiple locations from one originating
location. These services can be used to facilitate multi-media networking
between high-speed devices such as work stations, super computers, routers and
bridges.

     Dark Fiber. We are building an approximately 7,500 route mile regional
fiber network, which we believe will be, upon completion, one of the region's
most extensive long-haul fiber networks. Much of this network is being built on
routes that are diverse from older existing networks. We are installing, on
average, a minimum of 96 fibers throughout our network with the intent of
retaining at least 24 fibers for our future use. The remaining 72 fibers are
available to sell or swap. The network has been designed with eight major rings
and connects nearly every primary, secondary and tertiary market in our region.

     As our network is completed, dark fiber is being offered for sale to other
carriers. Prices are established on an individual case basis, but generally
reflect the cost of construction and the total quantity of fiber being
purchased. Our contracts provide for the transfer of title to the fiber, whereas
many other providers retain title. Revenues are recorded at the time of sale for
fiber that is already available, and on a percentage-of-completion basis for
fiber segments that are still under construction. Additionally, we receive
maintenance and collocation revenues subsequent to the sale of the dark fiber.

SYSTEM SERVICES

     We provide offshore voice and data systems and services to the oil and gas
industry in the Gulf of Mexico. Satellite and microwave transmission media are
used depending on the type and location of the drilling rig involved. Our
communications systems are flexible and can be quickly re-aligned as rigs move
to new locations. We also sell and install telephone and switchboard equipment
to our offshore customers.

SALES AND CUSTOMER SUPPORT

     We offer an integrated package of local exchange, domestic and
international long distance, enhanced voice, data, Internet and dedicated
private line services to small and medium-sized businesses. We believe that
these businesses are seeking simplicity, value and outstanding customer service.
These businesses often lack the resources to have an in-house telecommunications
manager. Consequently, we believe "one-stop shopping" for most communications
services from a single supplier and bundling all services on a single bill
appeals to businesses' desire for simplicity. Bundling services also address
their desire for value when the bundling results in lower costs than obtaining
those same services from multiple vendors. Finally, outstanding customer service
is essential in establishing and maintaining customer relationships. We believe
that our direct sales efforts, bundled services and customer care programs
enable us to better meet the needs of our customers, rapidly penetrate our
target markets, capture a larger portion of our customers' communications
expenditures and enhance customer loyalty.

     Although the vast majority of our sales force is focused primarily on the
small and medium-sized business segment, we also provide services to and receive
a material portion of our revenues from carriers and large business customers.
Therefore, our sales force and customer care organizations are organized to
serve each of these three segments. Sales and marketing approaches in the
telecommunications market are market-segment specific, and we have divided our
sales force into three groups with the following approaches:

     o    Small and medium-sized businesses: We use direct sales with sales
          forces based locally in each market;

     o    Large businesses, government entities and institutions: We use our
          enterprise sales account teams to respond to the more complex
          requirements of these larger entities; and

     o    Wholesale carriers: We use a direct sales force, trade shows,
          established business relationships, competitive pricing and customized
          back office solutions.

     At year-end 1999, we had 11 sales offices, and we expect to have 18 sales
offices by year-end 2000.

     As of February 29, 2000, our direct sales force consisted of 223 people
(including account executives) supporting our integrated, carrier and systems
services customers. We intend to hire and train approximately 90 additional
account executives by the end of 2000 and an additional 120 account executives
by the end of 2001.

     As of February 29, 2000, we also had 234 independent sales agents located
throughout Texas, Oklahoma, Arizona, New Mexico and New York. Our agent program
was established in 1996, and consists primarily of independent telephone
equipment vendors authorized by us to market our products and services.
Authorized agents receive recurring commissions based on product, pricing,
volume of usage and customer retention. We have six agent managers who actively
recruit new agents.

     In markets where we have already collocated equipment in the central office
of the ILEC and can lease local access as an unbundled network element, we
intend to eventually target high-end, multi-line residential customers in
addition to our core business customers through telemarketing, direct mail, web
and other sales channels. We believe these high-end residential customers will
contribute to our network efficiency and overall profitability. We expect to
commence these residential marketing efforts in the fourth quarter of 2000,
primarily on an outsourced basis.


                                       6

     To support our carriers' carrier and integrated services customers, we
operate a call center in Dallas, Texas staffed by our customer service
representatives, who have completed a certification and training program
provided by us. To enhance their effectiveness, we provide ongoing training to
all customer service representatives. Our customer service department uses
on-line, real-time automated systems that provide notes from all prior contacts
with the customer, provide a complete account and payment history for customers
billed by us and enable the customer service representatives to provision new
services and modify existing services on all of our products.

COMPETITION

     Overview. The communications services industry is highly competitive,
rapidly evolving and subject to constant technological change. We face a variety
of existing and potential competitors, including:

     o    The ILECs in our current target markets,

     o    Other voice and data CLECs,

     o    Long distance carriers, and

     o    Potential market entrants, including cable television companies,
          shared tenant service companies, electric utilities, microwave
          carriers, satellite carriers, wireless telephone system operators and
          private networks built by large end-users.

     We compete primarily on the basis of price, customer service and the
ability to provide a variety of communications products and services.

     We intend to expand our fiber network to approximately 7,500 route miles
throughout the Southwest region by year-end 2001. We expect to compete with
numerous established and start-up national and regional fiber networks owned by
long distance carriers, ILECs and CLECs throughout the Southwest region. These
competitors include very large companies such as: AT&T, MCI WorldCom, Sprint
(MCI WorldCom has entered into an agreement to acquire Sprint), 360 networks,
Level 3, Williams, SBC, Qwest, TXU, Broadwing and IFN. Many of these companies
have greater name recognition, financial, personnel, technical and marketing
resources than we have. We also anticipate that other providers of local and
long distance telecommunications services will plan and construct fiber networks
that could compete with our network. Competing networks may also have advanced
fiber and operating capabilities similar to those of our network. Furthermore,
we expect that some of our competitors will compete in our geographic market and
directly with us for many of the same customers along a significant portion of
the routes along which we intend to operate.

     Local Exchange Service. Our business objective is to expand significantly
our operations to provide local exchange services. Regulation permitting us to
compete in the local service market has only recently been enacted into law,
following enactment of the Telecommunications Act of 1996 (the "1996
Telecommunications Act"). See "--Regulation and Licenses." Our primary
competitor in each of our existing and targeted markets is the ILEC. Examples
include Southwestern Bell, BellSouth and GTE, as well as very large long
distance carriers, such as AT&T, MCI WorldCom, and Sprint that are also offering
local services. The ILECs currently dominate the provision of local services in
their respective markets, and the ILECs and the very large long distance
carriers have greater name recognition and greater financial, technical,
network, marketing and personnel resources than we do. Those entities also hold
longer standing relationships with regulatory authorities at the federal and
state levels than we do.

     In addition to competition from ILECs, we also face competition from a
growing number of other CLECs. Although we believe that CLECs overall have only
captured approximately 4% of the local telecommunications market in our region
(as of year-end 1998 based on published FCC statistics), we nevertheless compete
to some extent with other CLECs in our customer segments. There are typically
several other CLECs competing in each metropolitan market we serve or plan to
enter. Examples of data and voice CLECs in our markets include Allegiance
Telecom, Inc., Covad Communications Group Inc., NEXTLINK Communications, Inc.,
NorthPoint Communications Group Inc., Rhythms NetConnections, Inc., Teligent,
Inc. and Winstar Communications Inc. In some instances, these CLECs have
resources


                                       7
<PAGE>   10


greater than ours and offer a wider range of services. Like us, many of the
CLECs in our markets target small and medium-sized business customers.

     Domestic and International Long Distance. We provide long distance services
using our own facilities and by reselling the facilities of other carriers, both
in the United States and between the United States and other countries. The long
distance communications industry is intensely competitive, and the marketing and
pricing decisions of the larger industry participants such as AT&T, MCI
WorldCom, and Sprint have a significant impact on us. MCI WorldCom has entered
into an agreement to acquire Sprint. Significant consolidation in the industry
has created and will continue to create numerous other entities with substantial
resources to compete for long distance business. Such entities include Global
Crossing Ltd., Broadwing Communications and Qwest. In addition, the FCC has
recently granted approval to one of the RBOCs to provide in-region long distance
service in New York and other RBOCs may be approved to enter the long distance
market in additional states in the future. In January 2000, SBC Communications
filed an application with the FCC to provide long distance services in Texas.
GTE does not require FCC approval and may enter the long distance market now.
These larger competitors have significantly greater name recognition and greater
personnel, financial, technical, network and marketing resources. Many may also
offer a broader portfolio of services and have long standing relationships with
the customers targeted by us. Moreover, we cannot guarantee that our competitors
cannot negotiate contracts with suppliers of telecommunications services to
obtain conditions of service more favorable than ours. Many of our competitors
enjoy economies of scale that can result in a lower cost structure for
transmission and related terminating costs. Those carriers could bring
significant pricing pressure to bear on us.

     Customers frequently change long distance providers in response to lower
rates or promotional incentives by competitors. Prices for domestic and
international long distance calls have declined in recent years and we expect
them to continue to decrease further and more rapidly. Indeed, we expect
competition in all of our relevant markets to increase. This increased
competition could adversely affect our net revenue per minute and gross margins.
We cannot guarantee that we can compete effectively in the domestic or
international long distance markets.

EMPLOYEES

     As of February 29, 2000, we employed approximately 787 people, including
approximately 258 in sales and marketing, approximately 244 in engineering and
technical services, approximately 144 in provisioning and customer care and
approximately 141 in management, administration and finance. At that date, we
also had an agent sales force numbering approximately 234 independent sales
agents throughout Texas, Oklahoma, Arizona, New Mexico and New York. We use the
services of independent contractors for construction of our fiber network. None
of our employees is represented by a labor union or is subject to a collective
bargaining agreement. We believe that we have good relations with our employees.

REGULATION AND LICENSES

     The following summary of regulatory developments and legislation does not
purport to describe all present and proposed federal, state and local
regulations and legislation affecting the communications industry. Other
existing federal, state and local legislation and regulations are currently the
subject of judicial proceedings, legislative hearings, and administrative
proposals which could change, in varying degrees, the manner in which this
industry operates. Neither the outcome of these proceedings, nor their impact
upon us or the communications industry, can be predicted at this time. This
section also sets forth a brief description of regulatory and tariff issues
pertaining to our operations.

     We provide domestic and international services subject to varying degrees
of U.S. federal, state and local regulation, and regulation by foreign
authorities. In the United States, the Communications Act of 1934 (the "1934
Communications Act"), as amended, including the regulations promulgated by the
FCC thereunder, as well as the applicable laws and regulations of the various
states and state regulatory commissions all govern the provision of
telecommunications services. The FCC exercises jurisdiction under Title II of
the 1934 Communications Act over all facilities of, and services offered by,
telecommunications common carriers to the extent such services involve
jurisdictionally interstate common carrier communications, including
international communications originating from or terminating in the United
States. State regulatory authorities retain jurisdiction over jurisdictionally
intrastate communications. Under Title III of the 1934 Communications Act, the
FCC also regulates the licensing and


                                       8
<PAGE>   11


use of the radio frequency spectrum. Local governments sometimes impose
franchise or licensing requirements on local service competitors and/or
facilities companies. Services we provide in other countries remain subject to
the telecommunications laws and regulations of those countries.

     The FCC and the state regulatory agencies impose and enforce regulatory
requirements applicable to our operations. The FCC and the state regulatory
agencies may address regulatory non-compliance with a variety of enforcement
mechanisms, including monetary forfeitures, refund orders, injunctive relief,
license conditions, and/or license revocation.

     As a telecommunications carrier, we must also comply with the Federal
digital wiretapping administered by the U.S. Department of Justice and the FCC.
Telecommunications industry regulation varies substantially from state to state
and continues to change rapidly. Moreover, as deregulation at the federal level
occurs, some states are reassessing the level and scope of regulation applicable
to carriers. Domestic or international regulators or third parties could raise
material issues with regard to our compliance or non-compliance with applicable
regulations. Future regulatory, judicial or legislative activities could have a
material adverse effect on our financial condition, results of operations or
cash flow.

U.S. FEDERAL REGULATION

     Local Service Regulation Under The 1996 Telecommunications Act. The 1996
Telecommunications Act, which amended the 1934 Communications Act, provided for
comprehensive reform of the United States' telecommunications laws. In passing
the 1996 Telecommunications Act, Congress sought to increase local competition
from newer competitors such as long distance carriers, cable TV companies and
public utility companies. The 1996 Telecommunications Act specifically requires
all LECs (including ILECs and CLECs) not to prohibit or unduly restrict resale
of their services, to provide dialing parity, number portability and
nondiscriminatory access to telephone numbers, operator services, directory
assistance and directory listings, to afford access to poles, ducts, conduits
and rights of way, and to establish reciprocal compensation arrangements for the
transport and termination of telecommunications. In addition, ILECs must provide
interconnection on certain terms and conditions, unbundled network elements,
resold local services at wholesale rates, reasonable public notice of any
changes in the information needed for transmission and routing services over
their communications facilities, and physical collocation of equipment necessary
for interconnection and access to unbundled network elements at the LECs'
premises.

     On March 31, 1999, the FCC released its Collocation Order which requires
ILECs to permit CLECs to collocate any equipment used for interconnection or
access to unbundled network elements even if that equipment includes switching
or enhanced service functions. On March 17, 2000, the United States Court of
Appeals for the District of Columbia Circuit vacated limited portions of the
Collocation Order, holding certain definitions contained in the FCC's rules are
impermissibly broad. The court remanded the Collocation Order in part for
further FCC consideration of these issues. The FCC will be instituting
proceedings to comply with the Court's remand.

     Under the 1996 Telecommunications Act, RBOCs have the opportunity to
provide out-of-region long distance and certain cable TV services immediately
and in-region long distance services after the RBOCs meet certain conditions.
Specifically, an RBOC can enter the market for in-region long distance services
within areas where the RBOC provides local exchange service upon FCC approval
based on a showing that facilities-based competition and interconnection
agreements meeting a 14-point checklist both exist. Entry of RBOCs into the
domestic and international long distance business and the emergence of other new
local competitors could subject us to substantial competition and could have a
material adverse effect on our financial condition, results of operations and
cash flow.

     On August 8, 1996, the FCC released the Interconnection Decision, which
established a framework of minimum, national rules enabling state commissions
and the FCC to begin implementing many of the local competition provisions of
the 1996 Telecommunications Act. Among other things, the Interconnection
Decision prescribed certain minimum points of interconnection, adopted a minimum
list of unbundled network elements that ILECs must make available to
competitors, and adopted a methodology for states to use when setting prices for
unbundled network elements and for wholesale resale services. On January 25,
1999, the Supreme Court issued an opinion overturning prior decisions issued by
the U.S. Court of Appeals for the Eighth Circuit that had vacated certain
portions of the Interconnection Decision. The Eighth Circuit


                                       9
<PAGE>   12


decisions and their reversal by the Supreme Court perpetuate continuing
uncertainty about the rules governing the pricing, terms and conditions of
interconnection agreements. During the pendency of the Eighth Circuit
proceedings, state public utilities commissions have continued to conduct
arbitrations, and to implement and enforce interconnection agreements. However,
the Supreme Court's ruling and further proceedings on remand may affect the
scope of the state commissions' authority to conduct such proceedings or to
implement or enforce interconnection agreements. The U.S. Supreme Court's
decision has resulted in new and additional rules being promulgated by the FCC.
Given the general uncertainty surrounding the effect of the Eighth Circuit
decisions, the decision of the Supreme Court reversing them, and subsequent
proceedings, we cannot guarantee that we can continue to obtain or enforce
acceptable interconnection terms or interconnection terms consistent with our
business plans.

     On August 7, 1998, the FCC released an Order denying requests by various
ILECs that the FCC use Section 706 of the 1996 Telecommunications Act to forbear
from regulating advanced telecommunications services. If the FCC does forbear
from regulating advanced telecommunications services, such a decision would
increase the ability of ILECs to compete against less established carriers such
as us.

     Domestic Interstate Services. The FCC considers domestic interstate common
carriers (including us) that do not have market power as "nondominant." The FCC
subjects nondominant carriers to minimal regulation. However, interstate
carriers offering services to the public must comply with the federal statutory
and regulatory requirements of common carriage under the 1934 Communications Act
and file various reports and pay various fees and assessments. Among other
things, interstate common carriers must offer service on a non-discriminatory
basis at just and reasonable rates. Nondominant carriers need not obtain
specific prior FCC approval to initiate or expand domestic interstate services,
although they must file a tariff with the FCC. Nondominant carriers remain
subject to the FCC's complaint jurisdiction. In particular, we may be subject
to complaint proceedings in conjunction with alleged noncompliance such as
unauthorized changes in a customer's preferred carrier. In the event that the
FCC finds that we have violated an applicable rule or regulation, due to a
complaint, noncompliance with a fee payment or other reporting requirement or
an internal investigation, the FCC retains broad authority to impose various
sanctions or penalties.

     International Service Regulation. As a provider of international
telecommunications services, we must comply with the federal statutory and
regulatory requirements of common carriage under the 1934 Communications Act.
International common carriers must obtain authority from the FCC under Section
214 of the 1934 Communications Act and file a tariff containing the rates,
terms, and conditions applicable to their services before initiating their
international telecommunications services. We hold global authority from the FCC
to provide resale of switched services and private line services (where
permitted by the FCC) and to provide facilities-based services. We maintain an
international tariff on file with the FCC. Carriers holding Section 214
authority must also comply with FCC rules requiring, among other things, prior
approval for most transfers of control and assignments. Authorized international
carriers must also comply with the FCC's international service regulations,
including the International Settlements Policy ("ISPY") which governs the
payment settlements between U.S. common carriers and their foreign
correspondents for terminating traffic over each other's networks, the
accounting rates for such settlements, and the permissible deviations from these
policies.

     The FCC also recently approved significant reform of its ISPY, and
deregulated intercarrier settlement arrangements between U.S. carriers and
non-dominant foreign carriers and arrangements with all foreign carriers on
competitive routes. The ISPY reform will open new opportunities for U.S.
carriers to enter into innovative, economic traffic arrangements with foreign
carriers, but will also likely increase competition in the international
services market. The FCC also streamlined Section 214 license and related
requirements. While these rule changes may provide carriers with more
flexibility to respond more rapidly to changes in the global telecommunications
market, they will also likely increase the level of competition in the
international telecommunications marketplace.

     Wireless Services. We own and maintain a variety of telecommunications
infrastructures and we hold various FCC and international licenses to transmit
voice and data. We currently hold numerous FCC licenses to provide land mobile,
microwave and satellite communications services. See "-- Licenses."

     FCC licensees authorized to provide microwave, satellite earth station and
land mobile service must comply with requirements under Title III of the 1934
Communications Act and a variety of detailed licensing, operational and
technical requirements specific to each service. The 1934 Communications Act
generally limits direct foreign ownership of wireless licenses to 20%, but
provides for indirect foreign ownership holdings above 25% upon FCC approval. In
its order implementing the U.S. commitment under the WTO Agreement, the FCC
established new rules that effectively relax the foreign ownership limits for
common carrier wireless licenses. Specifically, the new rules allow for up to
100% indirect ownership of


                                       10
<PAGE>   13


wireless licenses by foreign interests from countries that are members of the
WTO upon FCC review and approval from countries that have participated in the
WTO Agreement.

     Access Charges. The cost of providing long distance and local exchange
services will be affected by changes in the "access charge" rates imposed by
ILECs on long distance carriers for origination and termination of calls over
local facilities. The term "access service" describes the use of local exchange
facilities for the origination and termination of interexchange communications.
On May 16, 1997, the FCC released an order intended to reform the FCC's system
of interstate access charges to make that regime compatible with the
pro-competitive deregulatory framework of the 1996 Telecommunications Act. The
FCC's access reform order adopts various changes to federal policies governing
interstate access service pricing designed to move access charges, over time, to
more economically efficient levels and rate structures. Among other things, the
FCC modified rate structures for certain non-traffic sensitive access rate
elements, moving some costs from a per-minute-of-use basis to flat-rate
recovery, including one new flat rate element, changed its structure for
interstate transport services, and affirmed interstate access charges do not
apply to ISPs.

     In response to claims that existing access charge levels are excessive, the
FCC stated that it would rely on market forces first to drive prices for
interstate access to competitive levels but that a "prescriptive" approach might
be considered if necessary. In the absence of competition, the FCC stated that
it might specify the nature and timing of changes to existing access rate
levels. The interstate access charges of ILECs are subject to extensive
regulation by the FCC, while those of CLECs are subject to a lesser degree of
FCC regulation, but remain subject to the requirement that all charges be just,
reasonable, and not unreasonably discriminatory.

     Line Sharing. On November 18, 1999, the FCC adopted a new order requiring
ILECs to provide line sharing, which will allow CLECs to offer data services
over the same line the consumer uses for voice services without the CLECs being
required to offer the voice services. State commissions have been authorized to
establish the prices to the CLECs for such services. The decision has been
appealed.

     Universal Service Charges. In 1997, the FCC released an order establishing
a significantly expanded federal universal service subsidy regime. Specifically,
the FCC established new universal service funds to support telecommunications
and information services provided to qualifying schools, libraries and rural
health care providers, and expanded the federal subsidies for local telephone
services provided to low-income consumers. Our payments for the schools and
libraries and rural health care fund depend on estimated quarterly intrastate,
interstate and international gross end-user telecommunications revenues.
Contribution factors vary quarterly and the FCC bills carriers on a monthly
basis. Contribution factors for the first quarter of 2000 are 5.877%. Because
the contribution factors do vary quarterly, we cannot currently accurately
determine the annualized impact on our annual performance.

     Internet Services. There are currently few U.S. laws or regulations which
specifically regulate communications or commerce over the Internet. One area in
which Congress did attempt to regulate information over the Internet involved
the dissemination of obscene or indecent materials. The constitutionality of
those provisions have been debated in litigation ongoing today and has been
subject to further litigation. In addition, in 1998 Congress passed the Digital
Millennium Copyright Act. That act provides ISPs that comply with its
requirements numerous protections from certain types of copyright liability. To
the extent that we have not met those requirements, third parties could seek
recovery from us for copyright infringements caused by our Internet customers.

     The law relating to the liability of ISPs for information carried on or
disseminated through their networks is currently unsettled. It is possible that
claims could be made against ISPs for defamation, negligence, copyright or
trademark infringement, or on other theories based on the nature and content of
the materials disseminated through their networks. We could be required to
implement measures to reduce our exposure to potential liability, which may
require, for instance, the expenditure of resources or the discontinuance or
modification of certain product or service offerings. Costs that may be incurred
as a result of contesting any claims relating to our services or the consequent
imposition of liability could have a material adverse effect on our financial
condition, results of operations and cash flow.

STATE REGULATION

     Most states require carriers to obtain a certification or other
authorization before offering local exchange and long distance intrastate
services. These certifications generally require a showing that the carrier has
adequate financial, managerial and technical resources to offer the proposed
services in a


                                       11
<PAGE>   14


manner consistent with the public interest. We hold long distance authorization
in most, but not all, of the states in which certificates are required. In
addition most states impose tariff requirements on carriers and require that
common carriers charge just and reasonable rates and not discriminate among
similarly situated customers. Some states also require the filing of periodic
reports, the payment of various regulatory fees and surcharges, and compliance
with service standards and consumer protection rules. States often require prior
approvals or notifications for certain transfers of assets (such as fiber cable
or other telecommunications facilities), customers, or ownership. Some states
also require approval or notice for the issuance of securities or debt or for
name changes. We have sought or expect to seek various additional authority in
some states. We cannot guarantee that we will be able to successfully obtain
such approvals. States generally retain the right to sanction a carrier or to
revoke certifications if a carrier violates relevant laws and/or regulations. If
any state regulatory agency concluded that we provide intrastate service without
the appropriate authority, or that we are not otherwise in compliance with state
public utility commission rules, that agency could initiate enforcement actions,
potentially including the imposition of fines, the disgorging of revenues, or
the refusal to grant the regulatory authority necessary for the future provision
of intrastate telecommunications services. We hold authority to provide
long distance and competitive local exchange services in certain states
including Arkansas, Kansas, Louisiana, Oklahoma and Texas, and have authority to
provide interexchange service in at least 41 states.

     In addition, carriers providing intrastate services must comply with state
utility commission rules and policies with respect to ILEC and CLEC competition,
geographic build out, mandatory de-tariffing and other matters. Certain states
have adopted specific universal service funding obligations. Numerous other
states have also instituted proceedings to adopt state universal service funding
obligations rules. State commissions generally have authority to impose
sanctions on carriers ranging from fines to license revocation to address
non-compliance with the states' particular regulatory policies and requirements.

     State regulatory agencies also regulate access charges and other pricing
for telecommunications services within each state. The RBOCs and other LECs have
sought reductions in state regulatory requirements, including greater pricing
flexibility. If regulators allow variable pricing of access charges based on
volume, we could face a competitive disadvantage in competing against larger
long distance carriers. We also could face increased price competition from the
RBOCs and other LECs for local and long distance services. In addition, the
removal of former restrictions on long distance service offerings by the RBOCs
as a result of the 1996 Telecommunications Act could further increase
competition. We cannot predict what impact of such rule changes might have on
our operations.

LOCAL GOVERNMENT AUTHORIZATIONS

     We also own telecommunications facilities that may be subject to certain
local government requirements, such as street use and construction permits and
licenses and/or franchises to install and expand fiber networks using municipal
rights of way. Termination of our existing franchise or license agreements
before their expiration dates or failure to renew those agreements and any
resulting requirement to remove facilities could have a material adverse effect
on our financial condition, results of operations and cash flow. In some
municipalities carriers must pay license or franchise fees based on a percentage
of gross revenues or on a per linear foot basis, as well as post performance
bonds or letters of credit. We cannot guarantee that we can retain existing
franchises or that franchise fees will remain at their current levels.

FOREIGN REGULATION

     International telecommunications providers are subject to varying degrees
of regulation in each of the jurisdictions in which they provide service. Local
laws and regulations, and the interpretation of such laws and regulations,
differ significantly from country to country. To the extent that we provide, now
or in the future, services in non-U.S. countries, we must comply with the laws
and regulations of foreign countries. The nature and extent of
telecommunications regulation varies significantly from country to country and
may include requirements that reflect closed or limited market access. We may
also face burdensome requirements to obtain initial licensing and encounter
operational and rate requirements in the relevant countries.


                                       12
<PAGE>   15
LICENSES

     We have received authorization, by virtue of state certification, tariff,
registration, or on a deregulated basis, to provide resold long distance
services in at least 41 states. In order to provide wireless mobile services, we
own various radio systems that provide two-way voice communications and have
obtained approximately 35 FCC licenses with approximately 300 frequency pairs.
These licenses have varying terms that expire and will require renewal. As each
license comes due for renewal, we will evaluate the need for such license and
elect to either renew the license or let it expire where, for example, we expect
no further need to use a particular license.

     We also operate as an FCC certificated Section 214 carrier to provide
resold switched telecommunications services. We have obtained common carrier
authority from the FCC to provide global resale of switched and private line
services as well as global facilities. We currently provide international
facilities-based private line service on a private carrier basis into Bolivia,
Bosnia, Croatia, Ecuador, Hungary and Russia.

     As part of our plans to increase service offerings, we have obtained
authority to provide competitive local exchange services and long distance
services in Arkansas, Kansas, Louisiana, Oklahoma and Texas. In addition, we
have received approval to have pole attachment rights to existing or future
facilities of Entergy, BellSouth and the State of Louisiana. Pole attachment
rights allow us to attach our own fiber cable to other parties' respective
utility poles. In addition, we own installed fiber cable placed under various
public and private rights of way.

DIGITAL WIRETAPPING

     The Communications Assistance to Law Enforcement Act ("CALEA"), enacted in
1994, requires telecommunications carriers to make available certain
telecommunications capabilities to U.S. law enforcement officials to permit
those authorities to continue to intercept communications involving advanced
technologies such as digital and wireless transmission communications. CALEA
imposes certain obligations on carriers to ensure that their equipment,
facilities and services will meet capability and capacity requirements in order
to provide law enforcement agencies the ability to intercept wireline and
wireless communications transmitted over those carrier's networks. Courts may
impose fines of up to $10,000 per day on telecommunications carriers that fail
to meet the required capability functions, as determined by industry standards.
Under procedures specified in CALEA, the U.S. Department of Justice ("DOJ")
recently filed a petition at the FCC challenging the technical capability
standard developed by the telecommunications industry. Because of the disputed
standard, several carriers sought an FCC extension of the October 25, 1998
capability compliance deadline. The FCC recently extended the compliance date
for the CALEA capability requirements to June 30, 2000 to permit manufacturers
sufficient time to develop CALEA compliant equipment. In the meantime, we expect
the FCC to issue shortly an order identifying the capabilities carriers, such as
us, will have to provide to law enforcement officials in order to meet CALEA's
requirements. Telecommunications carriers must also meet CALEA capacity
requirement mandating that by March 12, 2001, carriers enable a specific number
of simultaneous interceptions determined on a geographic basis. We cannot
predict the nature and extent of the impact the CALEA requirements will have on
us or on telecommunications carriers in general.

ITEM 2. PROPERTIES

     We own or lease buildings that contain approximately 270,000 square feet of
floor space. Our primary headquarters are located in Dallas, Texas. We own an
office building in Friendswood, Texas and an office building in Lafayette,
Louisiana, and we lease the remainder of our office space.

     All of the fiber, telecommunications equipment and other properties and
equipment used in our networks are owned or leased by us. We have entered into
various franchise, rights of way and lease agreements for network regeneration
sites. These properties and agreements do not lend themselves to description by
character and location of principal units and are not considered meaningful for
this disclosure. Our principal facilities include:

</TABLE>

     We consider our facilities adequate for our current needs and believe that
suitable additional space will be available, as needed, to accommodate further
physical expansion of corporate operations and for additional sales and service.
We are currently negotiating a lease for an approximately 80,000 square foot
facility for our call center, network operations center and information
technology center to be located in Dallas. However, we cannot assure you that we
will enter into a lease for this facility or any other facility or that if we
enter into a lease for such a facility, we will be able to obtain it on terms
favorable to us.

ITEM 3. LEGAL PROCEEDINGS

     We are a party to ordinary litigation incidental to our business from time
to time. Currently, we are not a party to any litigation that we expect would
have a material adverse effect on our results of operations, financial condition
or cash flow.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     None.

DIVIDEND POLICY

     We do not anticipate paying any cash dividends in the foreseeable future.
Any future determination to pay dividends will be at the discretion of our Board
of Directors and will be dependent upon then existing conditions. In addition,
the indentures for our 1998 Senior Notes and our 1999 Senior Notes effectively
prohibit us from paying cash dividends for the foreseeable future.

     Information pertaining to working capital restrictions and other
limitations upon the payment of dividends is incorporated herein from Item 7 --
Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources.

ITEM 6. SELECTED FINANCIAL DATA

     The following table sets forth financial data as of and for the years ended
December 31, 1995, 1996, 1997, 1998 and 1999. The business combination among our
predecessor companies was completed on August 26, 1998 and was accounted for as
a pooling of interests. Accordingly, the Consolidated Financial Statements
include our three predecessor companies (CapRock Telecommunications, CapRock
Fiber and CapRock Services) as though these entities were always a part of
CapRock.

     In May 1998, CapRock Services changed its fiscal year end to coincide with
the fiscal years of CapRock, CapRock Telecommunications and CapRock Fiber. The
Consolidated Statement of Operations for the year ended December 31, 1996
combines the operating activity of CapRock Services for the year ended June 30,
1996 with the operating activity of CapRock Telecommunications and CapRock Fiber
for the year ended December 31, 1996. The net income of CapRock Services in the
amount of approximately $260,000 for the six month period ended December 31,
1996 was excluded from the Consolidated Statement of Operations for the year
ended December 31, 1996 as a result of the non-conforming year ends for such
period. This amount was included as an adjustment to retained earnings in the
Consolidated Statement of Stockholders' Equity and Comprehensive Income in 1997.
CapRock Services' cash flow for this period was added to the 1997 beginning
balance in the Consolidated Statement of Cash Flows.

(a)  EBITDA consists of earnings before interest, income taxes, depreciation and

     in the communications industry to analyze companies on the basis of
     operating performance. EBITDA is not a measure of financial performance
     under generally accepted accounting principles and should not be considered
     as an alternative to net income as a measure of performance nor as an
     alternative to cash flow as a measure of liquidity.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     The following discussion and analysis should be read in conjunction with
the Consolidated Financial Statements and Notes thereto included in this Annual
Report on Form 10-K. See "Item 8 -- Financial Statements and Supplemental Data."
This information is not necessarily indicative of future operating results.
Except for the historical information contained below, the matters discussed in
this section are forward-looking statements that involve a number of risks and
uncertainties. Our actual liquidity needs, capital resources and operating
results may differ materially from the discussion shown below in these
forward-looking statements.

OVERVIEW

     We are a leading facilities-based integrated communications service
provider to small and medium-sized business and communications carrier customers
in the Southwestern United States. We offer business customers an integrated
bundle of communications products and services including local exchange,
domestic and international long distance, enhanced voice, data, Internet and
dedicated private line services. Additionally, we offer our
communications-intensive and carrier customers dark fiber, high bandwidth
dedicated fiber infrastructure, terminating access for domestic and
international long distance and ATM, frame relay and IP data transport services.
We believe that our current and planned networks will provide our customer base
the most comprehensive service alternative when compared to the incumbent and
other competitive communications service providers in our region.

     Our communications services are provided over our scalable fiber, voice and
data networks, which upon completion, will connect nearly every primary,
secondary and tertiary market in the six-state region of Texas, Louisiana,
Arkansas, Oklahoma, New Mexico and Arizona. At year-end 1999, our inter-city
long-haul fiber network consisted of approximately 3,000 route miles, which we
expect to expand to approximately 7,000 route miles by year-end 2000.

     Building and expanding our network and infrastructure has required and will
continue to require us to incur significant capital expenditures, primarily
consisting of the costs to build our fiber network, deploying our voice and data
switches and increasing the number of our central office collocations. As of
December 31, 1999, we have completed 31 central office collocations and intend
to expand that number to 200 collocations by the end of 2000. We plan to equip
at least 100 of these collocations so that we can provide DSL services on a
wholesale and retail basis. These collocations enable us to provide local
exchange and other services on our own network infrastructure, which
significantly lowers our cost of providing these services. Additionally, we have
deployed 13 data switches as of December 31, 1999, which we expect to expand to
17 data switches by the end of 2000.

     We have strategically entered into several joint build fiber arrangements,
which will significantly reduce our construction costs. To date, we have entered
into joint build fiber arrangements with Enron Communications, AT&T, 360networks
Inc. and Pathnet. The joint build fiber arrangements provide several benefits,
including reduction of construction costs, accelerated acquisition of rights of
way, and the freeing up or resources to focus attention on the construction of
other portions of the network. To further reduce the cost of building our
networks, we intend to sell excess dark fiber with the intent to retain at least
24 fiber strands for our own use.

RESULTS OF OPERATIONS

     In August 1998, we announced that we had completed a business combination
transaction in which our predecessor companies combined to form our company as
it exists today. The combination was accounted for as a pooling of interests.
Accordingly, our consolidated results include our three predecessor companies
(CapRock Telecommunications, CapRock Fiber and CapRock Services) as though these
entities have always been a part of CapRock.

     To measure our progress, we classify our revenue into three categories:
carriers' carrier, integrated services and systems services.


                                       17
<PAGE>   20


     Carriers' Carrier. Carriers' carrier revenue includes all carrier revenues
generated from the sale of domestic and international long distance, from the
sale of T-1 and DS-3 broadband capacity and from the sale and lease of dark
fiber. The revenue generated from international long distance services
represents minutes of traffic generated by domestic U.S.-based long distance
carriers terminating in foreign countries. These revenues are recognized when
the services are provided. The cost of revenue associated with these services is
based primarily on the direct costs associated with owned and leased
transmission capacity and the cost of transmitting and terminating traffic on
other carriers' traffic facilities. Commissions paid to sales representatives or
agents to acquire customer call traffic are expensed in the period when
associated call revenues are recognized.

     Dark fiber sales are generally referred to as IRUs (indefeasible right to
use). These sales are non-recurring. Revenues are recognized immediately on IRUs
sold from available fiber on completed network segments and on the percentage of
completion basis on IRUs sold from network segments under construction. Payment
is generally received at the time of sale, or shortly thereafter, for IRUs sold
on completed network segments. Payment is generally received over contractual
milestones for IRUs sold from network segments under construction. In both
scenarios, payments are received within one year from the time of sale. Revenue
attributed to IRUs was $9.5 million in 1998 and $76.1 million in 1999. Revenue
attributed to IRUs beyond 2001 are anticipated to decline as we deplete our dark
fiber available for sale. We expect revenues from our new service offerings to
offset this decline in our IRU revenues.

     Recent accounting pronouncements have affected the recognition of revenue
associated with IRUs entered into after June 30, 1999. See "--New Accounting
Pronouncements." Accordingly, revenue from the sale of IRUs that convey title to
the purchaser will be recognized as a sale either on a percentage-of-completion
basis or in its entirety if the fiber build has been completed. Revenue from IRU
sales that do not convey title to the purchaser will be recognized over the life
of the IRU. All of our IRU sales since July 1, 1999 have conveyed title to the
purchaser and, accordingly, revenue from such sales has been recognized on a
percentage-of completion basis or in its entirety

     Revenues generated from dark fiber and capacity leases are generally
recognized in monthly installments over the lease term, which is generally a
lease term of less than ten years.

     Integrated Services. Integrated services revenue includes all revenues
generated from the sale of communications services primarily to small and
medium-sized business customers. These services include local exchange, domestic
and international long distance, enhanced voice, data, Internet and dedicated
private line services and soon, DSL services. We record revenues and the related
cost of services at the time of customer usage.

     Our local services include revenues from local switched and enhanced
services, such as caller ID and call waiting. We began offering local exchange
services to our customers in 1998. We have been successful in selling our
integrated services to customers and have sold 61,067 local access lines as of
year-end 1999, of which 40,422 were installed lines. The remaining 20,645 local
access lines were in various stages of customer provisioning at December 31,
1999. We are currently introducing initiatives to reduce the provisioning cycle
time and our backlog of lines. These initiatives include, among other things,
electronic bonding with the ILEC, which allows our systems to communicate with
those of the ILEC on an automated basis.

     Our long distance revenue consists of both switched access and dedicated
access. Switched access services include "one plus long distance," whereby a
customer has selected CapRock as their long distance provider, toll free
800/888/877 service and calling cards. These services are offered for both
domestic and international calling. Dedicated access service is generally for
larger users with sufficient traffic volume to warrant the use of dedicated
private lines that directly connect the end user to our switch. As of December
31, 1999, we had approximately 85,000 active long distance lines.

     Revenues from integrated services are the foundation for our future growth
and will expand as we increase our customer base and our product offerings to
small and medium-sized business customers. Our primary competitors are the
ILECs. The table below provides key operational data relating to our integrated
services offering:

</TABLE>

     Due to our expanding switching platform and collocations, we anticipate
that in 2000 we will have additional revenue sources from access charges and
from the offering of new services, such as DSL. Access charges represent fees
for connecting CapRock local service customers to their selected long distance
carriers (originating access) and for delivering inbound long distance to
CapRock customers (terminating access). Additionally, we believe that we will be
able to offer dedicated access to our customers for voice and data services on
our network through private lines and virtual private networks. These services
and charges will be recognized as revenue as the services are provided.

     Systems Services. Systems services revenue includes revenues generated from
the design, installation, leasing and sale of voice and data systems and
products typically to offshore oil and gas industry customers in the Gulf of
Mexico. Satellite and microwave transmission media are used depending on the
type and location of the drilling rig involved. We also install telephone and
switchboard equipment to offshore customers. These revenues are recognized as
the services are provided. We will continue to provide these services to our
customer base, however, as our other revenue sources continue to grow, this
component of our business will become a smaller percent of revenues.

     The following table represents the various sources of revenues:

</TABLE>

YEAR ENDED 1998 COMPARED TO 1999

     Revenues. Total revenues increased $70.8 million, or 58%, from $121.8
million in 1998 to $192.6 million in 1999. This increase was attributable to
increases of 75% in carriers' carrier, 130% in integrated services and offset by
a decrease of 6% in systems services revenue.

     Carriers' carrier revenue increased $60.6 million from $80.6 million in
1998 to $141.2 million in 1999. The 75% increase resulted primarily from the
sale of IRUs and dark fiber leases. Minutes of use associated with our carrier
business increased from approximately 739.9 million minutes in 1998 to 861.7
million in 1999. The average revenue per carrier minute was approximately $0.11
per minute in 1998 and $0.16 per minute in 1999. The increase in the revenue per
minute is attributable to a higher percentage of international traffic
terminated to countries (other than Mexico) with a higher revenue per minute
rate. We anticipate that long distance competitive pressures will continue to
drive down prices, but the price decline will be partially offset by increased
volumes. Fiber related revenues, attributed to IRUs, increased $66.6 million
from $9.5 million in 1998 to $76.1 million in 1999. We anticipate revenue
relating to IRUs to continue at comparable levels through 2000 and decline in
subsequent years. However, period-to-period fluctuations can be expected as this
type of revenue is affected by the negotiation and terms of these contracts and
the build out of our network. We derived approximately $42.6 million and $37.9
million or 35% and 20% of our revenue from traffic terminated to international
countries in 1998 and 1999, respectively. Revenue per minute for a majority of
the international countries, particularly Mexico, continues to decrease as a
result of deregulation in the countries and increased competition.

     Integrated services revenue increased $12.4 million from $9.5 million in
1998 to $21.9 million in 1999. The 130% increase was attributable to growth in
the number of business customers both from increased penetration in our existing
markets and from the deployment of our network into new markets. Access lines
sold increased from 5,736 at the end of 1998 to 61,067 at the end of 1999.
Installed access lines increased from 5,736 at the end of 1998 to 40,422 at the
end of 1999. Our direct sales force increased from 75 at the end of 1998 to 200
at the end of 1999. We now have sales offices in Dallas, Fort Worth, Houston,
San Antonio, Austin, Corpus Christi and Victoria, Texas, Lafayette and New
Orleans, Louisiana and Phoenix, Arizona. We anticipate increased revenue from
integrated services as our networks are further deployed in new markets and as
our sales force for this revenue segment continues to grow.

     Systems services revenue decreased $2.0 million from $31.6 million in 1998
to $29.6 million in 1999. The 6% decrease was attributable to a moderate
reduction in the leasing and sale of voice and data systems and fewer projects
involving the engineering and integration of telecommunications systems and
sales, service and maintenance of telecommunications equipment. We anticipate
systems services revenue in 2000 will remain at levels comparable to 1999.


                                       20
<PAGE>   23


     Cost of Services. Cost of services increased $32.5 million, or 39%, from
$83.2 million in 1998 to $115.7 million in 1999. The increase in cost of
services was primarily attributable to the continued growth in revenue. The
eight percentage point increase in gross margin from 32% to 40% resulted
primarily from lower per minute costs attributable to higher traffic over our
network and the sale of dark fiber. The increase in the gross margin in 1999 was
partially offset by lower margins attributable to international traffic. Gross
margins may vary in future periods as a result of these and other factors.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses ("SG&A") include salaries, benefits, occupancy costs,
commissions, sales and marketing expenses and administrative expenses. SG&A
increased $33.0 million, or 140%, from $23.5 million in 1998 to $56.5 million in
1999. The increase resulted primarily from the additional personnel required to
support our growth, advertising to increase name recognition and brand awareness
and additional sales commission payments.

     We recorded merger related expenses of $2.3 million in 1998, as compared to
no such costs in 1999. The merger related expenses relate to the business
combination of CapRock Telecommunications, CapRock Fiber and CapRock Services,
our predecessor companies. This combination was consummated on August 26, 1998.
The merger related expenses consist of fees for investment bankers, attorneys,
accountants, financial printing and other related charges.

     Depreciation and Amortization Expense. Depreciation and amortization
expense increased $4.8 million, or 98%, from $4.9 million in 1998 to $9.7
million in 1999. This increase resulted primarily from additional fiber segments
placed in service and purchases of additional equipment and other fixed assets
to accommodate our growth. We expect that depreciation and amortization expense
will continue to increase in subsequent periods as we continue to expand our
facilities and place additional fiber segments in service.

     Interest Expense. Interest expense increased $17.8 million from $9.5
million in 1998 to $27.3 million in 1999. The increase resulted from interest
expense related to our 1998 Senior Notes and our 1999 Senior Notes. See
"--Liquidity and Capital Resources."

     Interest Income. Interest income increased $6.4 million from $3.0 million
in 1998 to $9.4 million in 1999. The increase was attributable to the interest
and investment accretion associated with the marketable securities purchased
with the proceeds from our 1998 Senior Notes and our 1999 Senior Notes.

     Income Tax Expense (Benefit). In 1998, we incurred income tax expense of
$1.3 million compared to an income tax benefit of $2.1 million in 1999. The
expense or benefit resulted from the income or loss for the respective periods.
The effective tax rates for 1998 and 1999 were 85% and 37%, respectively. The
effective tax rate for 1998 was higher than the effective tax rate for 1999 due
to the non-deductibility of certain merger related costs.

     Net Income (Loss). Net income decreased $3.7 million from net income of
$223,000 in 1998 to a net loss of $3.5 million in 1999 as a result of the
factors discussed above.

YEAR ENDED 1997 COMPARED TO 1998

     Revenues. Total revenues increased $46.5 million, or 62%, from $75.3
million in 1997 to $121.8 million in 1998. The 62% increase was attributable to
increases of 93% in carriers' carrier, 10% in integrated services and 27% in
systems services revenue.

     Carriers' carrier revenue increased $38.8 million from $41.8 million in
1997 to $80.6 million in 1998. The 93% increase resulted primarily from the
rapid growth in domestic and international switched services sold to other
carriers and as a result of $9.5 million in IRUs in 1998; no such revenue from
IRUs was recorded before 1998.

     Integrated services revenue increased $876,000 from $8.6 million in 1997 to
$9.5 million in 1998. The 10% increase was attributable to growth in the number
of business customers both from increased penetration in our existing markets
and from the deployment of our network into new markets. Access lines sold and
billable access lines increased from none at the end of 1997 to 5,736 at the end
of 1998.


                                       21
<PAGE>   24


     Systems services revenue increased $6.7 million from $24.9 million in 1997
to $31.6 million in 1998. The 27% increase was attributable to growth associated
with the leasing and sale of voice and data systems products and projects
involving the engineering and integration of telecommunications systems and
sales, service and maintenance of telecommunications equipment. In 1997, system
services revenue included product resale revenue of $2.9 million as compared to
no product resales in 1998. The product resales to a single customer were
substantially complete in May 1997 and such revenues are not expected to
contribute in a material manner in future years.

     Cost of Services. Cost of services increased $30.7 million, or 59%, from
$52.5 million in 1997 to $83.2 million in 1998. The increase in cost of services
was primarily attributable to the continued growth in all three revenue
categories. The two percentage point increase in gross margin from 30% to 32%
resulted primarily from lower per minute costs attributable to higher traffic
and the sale of dark fiber. The increase in the gross margin in 1998 was
partially offset by lower margins attributable to international traffic, which
carries a lower gross margin percentage. Gross margins may vary in future
periods as a result of these and other factors.

     Selling, General and Administrative Expenses. SG&A increased $9.4 million,
or 67%, from $14.1 million in 1997 to $23.5 million in 1998. The increase
resulted primarily from the additional personnel required to support our growth,
advertising to increase name recognition and brand awareness, and additional
sales commission payments.

     We recorded merger related expenses of $2.3 million in 1998, as compared to
no such costs in 1997. The merger related costs relate to the business
combination of CapRock Telecommunications, CapRock Fiber and CapRock Services,
our predecessor companies. This combination was consummated on August 26, 1998.
The merger related expenses consist of fees for investment bankers, attorneys,
accountants, financial printing and other related charges.

     Depreciation and Amortization Expense. Depreciation and amortization
expense increased $1.6 million, or 46%, from $3.3 million in 1997 to $4.9
million in 1998. This increase resulted primarily from purchases of additional
equipment and other fixed assets to accommodate CapRock's growth. We expect that
depreciation and amortization expense will continue to increase in subsequent
periods as we continue to expand our facilities.

     Interest Expense. Interest expense increased $7.8 million from $1.7 million
in 1997 to $9.5 million in 1998. The increase resulted from interest expense
related to our 1998 Senior Notes. See "-- Liquidity and Capital Resources."

     Interest Income. Interest income increased $2.9 million from $132,000 in
1997 to $3.0 million in 1998. The increase was attributable to the interest and
investment accretion associated with the marketable securities purchased with
the proceeds from our 1998 Senior Notes.

     Income Taxes. Income tax expense of $1.5 million in 1997 was comparable to
the income tax expense of $1.3 million in 1998. The effective tax rate was 37%
in 1997 as compared to 85% in 1998. The increase in the effective tax rate was
primarily attributable to certain non-deductible merger related expenses in the
amount of approximately $1.8 million.

     Net Income. Net income decreased $2.3 million, or 91%, from $2.6 million in
1997 to $223,000 in 1998 as a result of the factors discussed above.

LIQUIDITY AND CAPITAL RESOURCES

     We had cash, cash equivalents and marketable securities of $97.3 million at
December 31, 1998, as compared with $188.3 million at December 31, 1999. The
increase was attributable to our debt and equity offerings completed during the
second quarter of 1999. This increase was partially offset by the utilization of
cash, cash equivalents and marketable securities for the build out of our fiber
network and increase in corporate overhead to support our growth.


                                       22
<PAGE>   25


     Our cash flow provided from operating activities for 1998 was $7.1 million
as compared to $13.3 million used in operating activities during 1999. The
change was primarily attributable to an increase in accounts receivable and
unbilled services, which increased from $19.9 million in 1998 to $116.4 million
in 1999, as well as the timing of certain capital expenditure payments to
vendors relating to the fiber network build out. IRU transactions typically have
longer payment terms than other accounts receivable activity due to contractual
milestones that must be met before payments are made. In the first quarter of
2000, we received over $50 million in payments relating to IRUs and the
reimbursement of joint build costs that were recorded as accounts receivable at
December 31, 1999.

     Cash used in investing activities in 1998 and 1999 was $134.4 million and
$264.6 million, respectively. Capital resources used for the purchase of
property, plant and equipment increased $164.4 million from $36.9 million in
1998 to $201.3 million in 1999. This increase primarily related to the purchase
of telecommunications equipment and costs incurred with the build out of our
fiber network. In 1998, we used $145.0 million to invest in marketable
securities as compared to $283.6 million in 1999. Cash received from the sale of
marketable securities was $48.0 million in 1998 and $198.0 in 1999.

     In July 1998, we issued $150 million aggregate principal amount of our 1998
Senior Notes. Interest on the 1998 Senior Notes is payable semi-annually in
arrears on January 15 and July 15 of each year, which commenced January 15,
1999, at the rate of 12% per year. The net proceeds from the offering of our
1998 Senior Notes was approximately $145 million, a portion of which was used to
repay all of our then-existing debt obligations, totaling $26.8 million.

     In May 1999, we sold 4,000,000 shares of our Common Stock at a price of
$22.00 per share in a public offering. We received net proceeds, after deducting
underwriting discounts and expenses payable by us, of approximately $81.9
million from the sale of our Common Stock.

     In May 1999, we issued $210 million aggregate principal amount of our 1999
Senior Notes. Interest on the 1999 Senior Notes is payable semi-annually in
arrears on May 1 and November 1 of each year, which commenced November 1, 1999,
at the rate of 11 1/2% per year. We received net proceeds from that offering,
after deducting the initial purchasers' discount and estimated expenses, of
approximately $201.2 million.

     The indentures governing the 1998 Senior Notes and the 1999 Senior Notes
contain certain restrictive operating and financial covenants, including
restrictive covenants relating to borrowing additional money, paying dividends
or making other distributions to our shareholders, limiting the ability of
subsidiaries to make payments to us, making certain investments, creating
certain liens on our assets, selling certain assets and using the proceeds from
those sales for certain purposes, entering into transactions with affiliates and
engaging in certain mergers or consolidations. The 1999 Senior Notes are senior
unsecured obligations and as such rank pari passu in right of payment with our
existing 1998 Senior Notes and with all of our future unsecured and
unsubordinated indebtedness. All of the covenants are subject to a number of
important qualifications and exceptions. These covenants may adversely affect
our ability to finance our future operations or capital needs or to engage in
other business activities that may be in our best interests.

     The remaining proceeds from the 1998 Senior Notes, the 1999 Senior Notes
and the Common Stock sold in May of 1999 have been, and will be, used to fund
capital expenditures for the construction of our fiber network, switching
equipment and other capital expenditures and to expand our sales offices, for
potential acquisitions and for general working capital purposes. Unutilized
funds have been invested in short-term, high-grade investment securities
classified as available for sale.

     We are also considering obtaining a revolving credit facility. We
anticipate that this credit facility, if obtained, would be approximately $100
million. The proceeds from this credit facility would be used in a similar
manner to the uses discussed for the senior notes issued by us. See "-- Credit
Facility."

     We expect to require significant financing for future capital expenditure
and working capital requirements. Capital expenditures will be required to,
among other things, (1) fund the construction and operation of our fiber
network, including the portion to be constructed through joint build
arrangements with AT&T, Pathnet, 360networks Inc. and Enron Communications, to
approximately 7,000 route miles throughout the Southwest region by the end of
2000 and to approximately 7,500 route miles by the end of 2001, (2) fund the
purchase and installation of voice and data switches, (3) fund the installation
of equipment associated with DSL services and the build out of


                                       23

collocation facilities, (4) fund the further development of our OSS and
information technology equipment, and (5) open an additional seven sales offices
in 2000 and add sales support and customer service personnel in markets
throughout Texas, Louisiana, Oklahoma, Arkansas, New Mexico and Arizona. We
currently estimate that our aggregate capital requirements will total
approximately $485 million for 2000 and approximately $285 million for 2001. In
addition to our cash and marketable securities, cash flow from operations and
sales of dark fiber, we will require additional sources of capital to fund our
capital expenditure requirements. Such additional sources may include one or
more public or private equity and/or debt offerings. However, no assurances can
be made as to whether we will be able to obtain these additional sources of
capital, and if we are unable to obtain them, we may have to curtail our level
of capital expenditures.

     We may require additional capital in the future for new business activities
related to our current and planned businesses, or in the event we decide to make
acquisitions, enter into joint venture and strategic alliances or expand into
new geographic regions. Sources of additional capital may include cash flow from
operations, public or private equity and debt financings, bank debt and vendor
financings. In addition, we may enter into joint construction agreements with
carriers, thereby reducing our capital expenditure requirements. However, we
cannot assure you that we will be successful in producing sufficient cash flow
or raising sufficient debt or equity capital to meet our strategic business
objectives or that such funds, if available, will be available on a timely basis
and on terms that are acceptable to us. If we are unable to obtain such capital,
the build out of portions of our expanded network may be significantly delayed,
curtailed or abandoned. In addition, we may accelerate the rate of deployment of
our network, which in turn may accelerate our need for additional capital. Our
actual capital requirements will also be affected, possibly materially, by
various factors, including the timing and actual cost of the deployment of our
network, the timing and cost of expansion into new markets, the extent of
competition and the pricing of dark fiber and telecommunications services in our
markets.

CREDIT FACILITY

     We may enter into a senior credit facility with one or more banks in the
amount of approximately $100 million. The final terms and conditions of the
credit facility will depend on negotiation of definitive documentation, however
the credit facility is expected to contain customary restrictive covenants,
including financial covenants.

NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activity" ("SFAS 133") which requires that all
derivatives be recognized in the statement of financial position as either
assets or liabilities and measured at fair value. In addition, all hedging
relationships must be designated, reassessed and documented pursuant to the
provisions of SFAS No. 133. In June 1999, FASB delayed the effectiveness of SFAS
133 to fiscal years beginning after June 15, 2000. The adoption of SFAS 133 will
not have an impact on our financial position, results of operations or cash
flows.

     In June 1999, the Financial Accounting Standards Board (the "FASB") issued
Interpretation No. 43, "Real Estate Sales, an interpretation of FASB Statement
No. 66." The interpretation is effective for sales of real estate with property
improvements or integral equipment entered into after June 30, 1999. Under this
interpretation, dark fiber is considered integral equipment and accordingly,
title must transfer to a lessee in order for a lease transaction to be accounted
for as a sales-type lease. The application of the provisions of FASB
Interpretation No. 43 did not have an impact on our financial position, results
of operations or cash flows.

     In December 1999, the SEC staff issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements" ("SAB 101"). SAB 101 summarizes
certain of the staff's views in applying General Accepted Accounting Principles
to revenue recognition and accounting for deferred costs in the financial
statements. Based on our current revenue recognition policies, SAB 101 is not
expected to materially impact our financial position, results of operations or
cash flows.

CONTINGENCIES

     We are party to ordinary litigation incidental to out business. No
currently pending litigation is expected to have a material adverse effect on
our results of operations, financial condition or cash flow.

YEAR 2000 READINESS

     We established a year 2000 committee made up of leaders from our
operational areas to assess our year 2000 readiness. The committee had the
involvement of senior management and the Board of Directors and its objectives
were a top priority. We undertook various initiatives intended to provide that
computer equipment and software would function properly with respect to dates in
the year 2000 and thereafter. We experienced no problems in our critical systems
subsequent to December 31, 1999 related to the year 2000, nor did we incur any
problems from critical system services provided by third parties. We spent less
than $250,000 addressing our year 2000 readiness through the end of 1999.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     We are exposed to market risk from changes in marketable securities (which
consist of money market and commercial paper). At December 31, 1999, our
marketable securities were recorded at a fair value of approximately $182.6
million, with an overall weighted average return of approximately 5% and an
overall weighted average life of less than 1 year. The marketable securities
held by us have exposure to price risk, which is estimated as the potential loss
in fair value due to a hypothetical change of 50 basis points (10% of our
overall average return on marketable securities) in quoted market prices. This
hypothetical change would have an immaterial effect on the recorded value of the
marketable securities.

     We are not exposed to material future earnings or cash flow fluctuations
from changes in interest rates on long-term debt since 100% of our long-term
debt is at a fixed rate as of December 31, 1999. The fair value of our long-term
debt at December 31, 1999 was estimated to be $371 million based on the overall
rate of the long-term debt of 11.71% and an overall maturity of 9 years compared
to terms and rates currently available in long-term financing markets. Market
risk is estimated as the potential decrease in fair value of our long-term debt
resulting from a hypothetical increase of 117 basis points in interest rates
(ten percent of our overall borrowing rate). Such an increase in interest rates
would result in approximately a $10 million decrease in fair value of our
long-term debt. To date, we have not entered into any derivative financial
instruments to manage interest rate risk and are currently not evaluating the
future use of any such financial instruments.

     We do not currently have any material exposure to foreign currency
transaction gains or losses. Substantially all business transactions are in U.S.
dollars. To date, we have not entered into any derivative financial instrument
to manage foreign currency risk and are currently not evaluating the future use
of any such financial instruments.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
CapRock Communications Corp.:

     We have audited the accompanying consolidated balance sheets of CapRock
Communications Corp. and subsidiaries, as of December 31, 1998 and 1999, and the
related consolidated statements of operations, stockholders' equity and
comprehensive income (loss), and cash flows for each of the years in the
three-year period ended December 31, 1999. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of CapRock
Communications Corp. and subsidiaries as of December 31, 1998 and 1999, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1999, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1998 AND 1999


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) Basis of Presentation and Nature of Business

     The consolidated financial statements include CapRock Communications Corp.
("CapRock" or the "Company") and its majority owned subsidiaries. The Company
was formed on February 3, 1998, to serve as a holding company for the operations
of CapRock Telecommunications Corp., a Texas corporation ("CapRock
Telecommunications"), CapRock Fiber Network Ltd., a Texas limited partnership
("CapRock Fiber"), and IWL Communications, Incorporated, a Texas corporation,
doing business as CapRock Services Corp. ("CapRock Services"), and its wholly
owned subsidiaries upon the consummation of the business combination of those
companies (the "Combination"). All significant inter-company transactions are
eliminated in consolidation. The equity method is used to account for
unconsolidated investments in companies in which the Company exercises
significant influences over operating and financial policies, but does not have
a controlling interest. On August 26, 1998, pursuant to the Agreement and Plan
of Merger and Plan of Exchange dated February 16, 1998, as amended (the "Merger
Agreement"), among the Company, CapRock Telecommunications, CapRock Fiber,
CapRock Services and certain other parties, the Company completed the
Combination (note 2).

     The Company is a regional facilities-based integrated communications
provider offering local, long distance, Internet, data and private line services
to small and medium-sized businesses. The Company also provides switched and
dedicated access, regional and international long distance, private lines and
dark fiber to carrier customers. The Company is in the process of building an
advanced fiber network throughout Texas, Louisiana, Oklahoma, Arkansas, New
Mexico and Arizona. Additionally, the Company, through its wholly owned
subsidiary - CapRock Services, provides communications solutions to customers
with operations in remote, difficult-access regions. The Company markets its
services through its internal sales representatives and a network of independent
agents.

     (b) Cash Equivalents and Short-Term Investments Available for Sale

     The Company considers all cash in bank accounts as cash equivalents.
Marketable securities consist of U.S. government, money market and commercial
paper securities, with maturities of less than one year. Marketable securities
are stated at cost and are adjusted for discount accretion and premium
amortization, which approximate fair value. The Company's short-term investment
objectives are safety, liquidity and yield.

     (c) Inventory

     Inventory substantially consists of parts and equipment held for resale.
Inventory that can be specifically identified using a unique identification
number is stated at the lower of specified cost or market. Inventory that cannot
be specifically identified is stated at the lower of cost or market, where cost
is determined using the first in first out method. Market value, in all cases,
represents the lower of replacement cost or net realizable value.

     (d) Property, Plant and Equipment

     Property, plant and equipment are stated at cost and include certain costs,
which are capitalized during the installation and expansion of the
telecommunications network including interest costs, payroll, general and
administrative costs related to the construction. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are amortized using the straight-line method over the
shorter of the estimated useful lives of the assets or the remaining terms of
the leases. Assets under construction are not depreciated until placed in
service.


                                      F-7

                  CAPROCK COMMUNICATIONS CORP. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     In the process of building out its fiber network, the Company may enter
into Indefeasible Right to Use contracts ("IRUs") for the sale of fiber usage
rights and to provide the construction services for such fiber. The Company may
install additional conduits for these segments included in the IRUs for its own
use while performing the construction services. This additional conduit is
capitalized proportionately with the number of conduits placed, and depreciation
begins for these costs as the specific fiber segment is placed in service.

     (e) Revenues and Cost of Revenues

     The Company recognizes revenue from the following sources: Carriers'
Carrier, Integrated Services and Systems Services.

     CARRIERS' CARRIER:

     Carriers' carrier revenue includes all carrier revenues generated from the
sale of domestic and international switched services, from the sale of T-1 and
DS-3 broadband capacity and from the sale and lease of dark fiber. The revenue
generated from international switched services represent minutes of long
distance traffic terminating in foreign countries, but generated by domestic
U.S. based long distance carriers. Such revenues are recognized when the
services are provided. The cost of revenues associated with these services is
based primarily on the direct costs associated with owned and leased
transmission capacity and the cost of transmitting and terminating traffic on
other carriers' facilities. Commissions paid to sales representatives or agents
to acquire customer call traffic are expensed in the period when associated call
revenues are recognized.

     The Company accounts for long-term construction contracts relating to the
development of telecommunications networks for customers using the
percentage-of-completion method, which would include the sale of fiber usage
rights through IRUs and the related construction services associated with
building the fiber network specified in the IRUs. Progress under the
percentage-of-completion is measured based upon costs incurred to date compared
with total estimated construction costs. Customers are billed based upon
contractual milestones.

     INTEGRATED SERVICES:

     Integrated services revenue includes all revenues generated from the sale
of telecommunications products to business and residential customers. These
products include local, long distance, Internet, data and private line services.
The Company records revenues for these telecommunications services at the time
of customer usage. The cost of revenues associated with services is based
primarily on the direct costs associated with owned and leased transmission
capacity and the cost of transmitting and terminating traffic on other carriers'
facilities. The cost of revenues for local services also includes payments to
local exchange carriers and interexchange carriers for access and transport
charges. Commissions paid to sales representatives or agents to acquire customer
call traffic are expensed in the period when associated call revenues are
recognized.

     SYSTEMS SERVICES:

     Systems services revenue includes revenues generated from the design,
installation, leasing and sale of voice and data systems and products, primarily
to companies in the oil and gas industry. The revenues associated with the
leasing and sale of voice and data systems products are recorded as the services
are provided. The revenue associated with the design and installation of voice
and data systems products primarily relates to communication system contracts
involving the engineering and integration of telecommunications systems and
sales, service and maintenance of telecommunications equipment. These contracts
are typically fixed price and such revenue is recognized based upon the
percentage-of-completion method, primarily based upon contract costs incurred to
date compared with total estimated contract costs. In 1997 systems services
revenue included product resales to a single customer which were substantially
complete in May 1997.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     (f) Business and Credit Concentration

     Financial instruments which potentially expose the Company to a
concentration of credit risk, as defined by SFAS No. 105, Disclosure of
Information about Financial Instruments with Off-Balance Sheet Risk and
Financial Instruments with Concentrations of Credit Risk, consist primarily of
accounts receivable from carriers, retail and commercial customers. The Company
extends credit to customers on an unsecured basis with the risk of loss limited
to outstanding amounts.

     (g) Income Taxes

     Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

     (h) Stock-Based Compensation

     The Company accounts for its stock-based employee compensation plan using
the intrinsic value based method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees ("APB No. 25"). As
such, compensation expense is recorded on the date of grant to the extent the
current market price of the underlying stock exceeds the exercise price. The
Company has provided pro forma disclosures as if the fair value-based method of
accounting for these plans, as prescribed by Statement of Financial Accounting
Standards ("SFAS") No. 123, Accounting for Stock-Based Compensation ("SFAS No.
123"), had been applied.

     (i) Foreign Currency Translation

     Results of operations for foreign investments are translated from the
designated functional currency to the U.S. dollar using average exchange rates
during the period, while assets and liabilities are translated at the exchange
rate in effect at the reporting date. Resulting gains and losses from
translating foreign currency financial statements are included in accumulated
other comprehensive income, a component of stockholders' equity.

     (j) Intangible Assets

     The Company recorded approximately $1.6 million of goodwill and $300,000
relating to other intangibles in connection with the acquisition of Integrated
Communications and Engineering Ltd. ("ICEL") (note 16). Goodwill represents the
excess of the purchase price over fair value of identifiable net assets acquired
and is amortized on a straight-line basis over the expected periods to be
benefited. Goodwill in connection with the acquisition of ICEL will be amortized
over 20 years. The Company assesses the recoverability of this intangible asset
by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows. The amount of goodwill impairment, if any, is measured based upon
projected discounted future operating cash flows using a discounted rate
reflecting the Company's average cost of funds. The assessment of the
recoverability of goodwill will be impacted if estimated future operating cash
flows are not achieved.

<PAGE>   46


                  CAPROCK COMMUNICATIONS CORP. AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     (k) Impairment of Long-Lived Assets

     The Company accounts for long-lived assets in accordance with the
provisions of SFAS No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of. The Statement requires that
long-lived assets and certain identifiable intangibles be assessed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the amount by which the carrying amount of the assets exceeds the fair value of
the assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell.

     (l) Fair Value of Financial Instruments

     The Company believes that the carrying amounts of its financial instruments
included in current assets and current liabilities approximate the fair value of
such items due to their short-term nature. As of December 31, 1999, the
estimated fair value and the carrying amount of the Company's 12% Senior Notes
due 2008 was $155.3 million and $145.7 million, respectively. As of December 31,
1999, the estimated fair value and the carrying amount of the Company's 11 1/2%
Senior Notes due 2009 was $215.3 million and $201.8 million, respectively.

     (m) Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts and disclosures. Accordingly,
actual results could differ from those estimates.

     (n) Earnings per Common Share

     In 1997, the Company adopted the Financial Accounting Standards Board
Statement No. 128 ("SFAS No. 128"), "Earnings Per Share". All earnings per share
amounts for all periods have been presented, and where necessary, restated to
conform to SFAS No. 128 requirements. (In thousands, except per share data).

</TABLE>

     For the year ended December 31, 1999, the effect of the Company's potential
common stock equivalents was omitted from the computation of diluted net loss
per common share as their effect would be antidilutive.

     (o) Comprehensive Income

     On January 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income" ("SFAS No. 130"). SFAS No. 130 establishes standards for
reporting and presentation of comprehensive income and its components in a full
set of financial statements. Comprehensive income consists of net

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


income and currency translation adjustments and is presented in the consolidated
statements of stockholders' equity and comprehensive income (loss). The
Statement requires only additional disclosures in the consolidated financial
statements; it does not affect the Company's financial position or results of
operations. Prior to 1998, the Company's comprehensive income only consisted of
net income.

(2) BUSINESS COMBINATION

     On August 26, 1998, pursuant to the Plan of Agreement of Merger and Plan of
Exchange dated February 16, 1998, as amended, the Company completed the mergers
with CapRock Telecommunications, CapRock Fiber and CapRock Services.
Accordingly, the Consolidated Balance Sheets as of December 31, 1998 and 1999
and the Consolidated Statements of Operations, Stockholders' Equity and
Comprehensive Income and Cash Flows for each of the years in the three year
period ended December 31, 1999 include CapRock Telecommunications, CapRock Fiber
and CapRock Services as though these entities had always been a part of CapRock.

     All previously outstanding shares of CapRock Services common stock ceased
to exist and each such share was converted into and became exchangeable for one
share of CapRock common stock, and all previously outstanding shares of CapRock
Telecommunications common stock ceased to exist, and each such share was
converted into and became exchangeable for 1.789030878 shares of CapRock common
stock and each one percent (1%) of the interests in CapRock Fiber issued and
outstanding was exchanged for 63,194.54 shares of CapRock common stock. The
Company issued 28,910,221 common shares in exchange for the outstanding common
share of CapRock Telecommunications, CapRock Fiber and CapRock Services.
Additionally, outstanding employee stock options of CapRock Services and CapRock
Telecommunications were converted at the above exchange factors into options to
purchase shares of CapRock common stock. The mergers and interest exchange
constituted a tax-free reorganization and was accounted for as a pooling of
interests.

     The transactions between CapRock, CapRock Services and CapRock Fiber have
been eliminated for all respective periods presented. Certain reclassifications
were made to CapRock Services financial statements to conform to CapRock's
presentations.

(3) MARKETABLE SECURITIES

     Investments in marketable securities at December 31, 1998 and 1999
consisted of money market investments of $46,666,281 and $9,974,718,
respectively and commercial paper securities of $50,353,508 and $172,661,433,
respectively.

     At December 31, 1998 and 1999, the estimated fair value of the Company's
commercial paper securities approximated cost, and the gross unrealized gains
and losses were not significant.

(11) LEASE CONTRACTS

     The Company provides telecommunications services to various customers under
operating leases. The services include agreements to lease capacity to customers
over the fiber optic line, communications equipment, line/satellite charges
and/or maintenance charges. These leases impose certain obligations on both the
lessor and lessee, which must be met during the term of the lease.

     A significant portion of these services requires that the Company have
access to international communication satellites. The Company has contracted
with a Russian entity for rights to access its portion of an international
communications satellite. The Company has agreed to pay a recurring monthly fee
to the entity based on the amount of satellite space segment utilized by each
lessee. Additionally, the Company has sold communication equipment to the
entity. The Company utilizes those facilities to provide communication services
to various United States energy and oil and gas companies and other customers
doing business in Russia.

     The deferred tax assets and liabilities are reflected in the financial

     A net operating loss of $11.5 million was available as of December 31, 1999
and will be available to offset future taxable income. The net operating loss
carryforward will expire in years 2018 and 2019; however, management believes
that this carryforward will be utilized prior to expiration. No valuation
allowance for deferred taxes at December 31, 1998 and 1999 is considered
necessary as management has determined that it is more likely than not that
these assets will be realized. The ultimate realization of deferred tax assets
is dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. The Company considered the
scheduled reversal of deferred tax liabilities, projected future taxable income,
and tax planning strategies in making this assessment.

(14) COMMITMENTS

     The Company has entered into joint build agreements where it manages the
project. As manager, the Company is committed to meeting various construction
milestones during the term of the project. In the event that the completion
dates for any of the milestones are not met by the Company, penalties are
imposed on the Company. Such penalties incurred by the Company have been
immaterial and the Company believes that future penalties would also be
immaterial.

     At December 31, 1999 the Company had committed to make payments totaling
$44.5 million relating to the purchase of IRUs.

     The Company has an agreement with various vendors, which require minimum
usage. In the event such monthly commitments are not met, the Company is
required to remit to the vendor the difference between the commitments and the
actual usage. Such amount, if necessary, would be recorded as cost of revenue in
the period incurred.

     The Company entered into a volume purchase commitment of $13 million
relating to the purchase of telecommunications equipment. In the event the $13
million commitment is not fulfilled by CapRock, the Company shall pay the vendor
a penalty ranging from 3%-13% of the purchase commitment. The Company believes
that no penalties will be incurred under this contract.

(15) 401(K) PLANS

     The Company offers its qualified employees the opportunity to participate
in one of its defined contribution retirement plans qualifying under the
provisions of Section 401(k) of the Internal Revenue Code. Each employee may
contribute on a tax deferred basis a portion of annual earnings not to exceed
$10,000. The Company matches individual employee contributions up to a maximum
level, which in no case exceeds 6%. The Company's matching contributions to the
plan (after forfeitures) for the years ended December 31, 1997, 1998 and 1999
were $30,287, $81,086 and $233,319, respectively.

(16) ACQUISITION

     In January 1998, the Company completed the acquisition of Integrated
Communications and Engineering, Ltd. ("ICEL"), a communications systems
integrator and maintenance provider in Aberdeen, Scotland. The Company paid a
total purchase price of approximately $2.2 million comprised of approximately
$610,000 in cash and 207,266 shares of the Company's common stock. The
acquisition was accounted for as a purchase business combination, and
accordingly the purchase price was allocated to assets acquired and liabilities
assumed. Approximately $1.6 million was recorded as goodwill and $300,000 was
allocated to contracts as a result of the transaction.

     The following summarizes the unaudited consolidated data as though the
acquisition of ICEL occurred as of the January 1, 1997 (in thousands):

     In January 2000, CapRock and 360networks Inc. (formerly Worldwide Fiber)
entered into a regional joint construction effort to jointly build approximately
1,300 miles of fiber network through Texas, New Mexico and Arizona. This will
also allow CapRock to increase the speed to market of its voice and high-speed
data services to cities along the route, including Tucson, Arizona; Santa Fe and
Albuquerque, New

Mexico; and El Paso, Midland, San Angelo, and Temple, Texas. The co-build
contract calls for CapRock to construct a Texas fiber route from El Paso through
Temple to Austin, while 360networks Inc. is responsible for laying fiber west of
El Paso through Tucson and into Phoenix. The projected budget for this
development is in excess of $100 million. CapRock and 360networks Inc. will each
own one conduit and will jointly own those remaining in the multi-conduit
segment. Construction is scheduled to begin in the first quarter of 2000 with
completion expected by year end.

(18) SEGMENT REPORTING AND CONCENTRATION OF CUSTOMERS

     In June 1997, the Financial Accounting Standards Board issued Statement No.
131, Disclosures about Segments of an Enterprise and Related Information, which
the Company has adopted in 1998. The Company identifies such segments based on
management responsibility. The Company measures segment profit as operating
income, which is defined as income before interest expense and income taxes. The
revenue for the Carriers' Carrier, Integrated Services and Systems Services are
discussed in note 1(e). The Corporate Division includes certain general and
administrative functions and operating expenses. Merger related expenses of $2.3
million were included in corporate, which comprise the segment operating loss of
$3.5 million in 1998. The general and administrative expenses were allocated to
each of the respective divisions prior to 1998. Information regarding operating
segments is as follows (in thousands):

     NOW, THEREFORE, for and in consideration of the premises and the mutual

hereby agree as follows.

                                    ARTICLE I

                                    AGREEMENT

Executive further agrees to hold such additional positions of the Employer as
may be assigned to him from time to time by the Board of Directors. In
performing such duties hereunder, Executive shall give Employer the benefit of
his special knowledge, skills, contacts and business experience. During the
Term, Executive will be the Company's full-time employee and, except as may
otherwise be approved in advance in writing by the Board of Directors, and
except during vacation periods and reasonable periods of absence due to
sickness, personal injury or other disability, the Executive will devote
substantially all of his working time and efforts to his duties under this
Agreement. Notwithstanding the foregoing, Executive may (i) manage personal and
family investments and (ii) serve as an officer, director, trustee or otherwise
participate in purely educational, welfare, social, charitable, religious and
civic organizations. In connection with his employment during the Term, unless
otherwise agreed by Executive, the Executive will be based at the Company's
principal executive offices in Dallas, Texas. It is the intent of the parties to
this Agreement that Executive shall be elected to fill the existing vacancy on
the Board of Directors at its next regularly scheduled meeting and shall

from time to time. Beginning in October 2000, the Executive's minimum base
salary shall be reviewed on an annual basis by the Compensation Committee.

                             CHANGES IN COMPENSATION

of Directors or the Compensation Committee thereof from increasing, in its sole
and absolute discretion, prospectively or retroactively, any compensation or

     greater than the closing price of the Employer's common stock on the
     trading day immediately preceding such public announcement, the number of
     options to purchase shares of the Employer's common stock shall be
     increased by a percentage equal to the percentage increase in the share
     price of the common stock of Employer.

          B. In addition, Executive will be entitled to participate in the
     Employer's annual stock option grant program commencing in 2001.

                               EXPENSES OF COUNSEL

     3.07 Employer hereby agrees promptly after the Effective Date to pay the
fees and expenses of Executive's counsel hired to represent Executive in
connection with entering into an employment relationship with Employer.

                                      LOANS

     3.08 A. Upon the Effective Date, Employer shall make a loan to Executive of
     Nine Hundred Thousand Dollars ($900,000) ("Loan") bearing interest at the
     prime rate of interest with the principal and interest payable in three
     payments on each of the first, second and third anniversaries of the
     Effective Date (each, a "Loan Payment Date"). All amounts owed under such
     Loan and not forgiven pursuant to Section 3.09 shall be immediately due and


                                       3
<PAGE>   4


     payable upon termination of Executive's employment. Executive agrees to
     execute a promissory note (the "Note"), in the form of that attached hereto
     as Exhibit "C" and incorporated herein by reference, to evidence the Loan.

          B. Subject to any limitations placed upon Employer by that certain
     Indenture dated as of May 18, 1999 between Employer and Chase Manhattan
     Trust Company, National Association, as trustee, (the "Indenture"),
     Employer will loan Executive an amount of money equal to Executive's excise
     tax liability under Section 4999 of the Internal Revenue Code (the "Tax
     Liability") that arises as a result of a "Change of Control" as defined in
     Employer's 1998 Equity Incentive Plan. Such loan shall be made in one or
     more installments at the time or times the Tax Liability is due to be paid
     by, or withheld from the compensation of, Executive, and shall have a
     maturity date not later than the earlier of (i) ninety days after Executive
     sells shares of Employer for consideration at least equal to the Tax
     Liability or (ii) three years. Such loan shall bear interest at the prime
     rate of interest with all principal and interest payable in one lump sum
     payment on the expiration date of such loan. Executive agrees to execute a
     promissory note, mutually agreed upon by the parties, to evidence the loan
     for the Executive's Tax Liability. To the extent the Tax Liability exceeds
     the principal amount of such loan, Employer shall promptly pay to Executive
     an amount in cash equal to such excess.

                                LOAN FORGIVENESS

     3.09 On each Loan Payment Date occurring during the Term of this Agreement,
Employer shall immediately forgive a portion of the Loan in an amount of
$300,000 plus any interest accrued and payable on the Loan as of such Loan
Payment Date. Upon a "Change of Control" as defined in Employer's 1998 Equity
Incentive Plan, or upon the termination of Executive's employment hereunder
pursuant to Section 5.02 (Incapacity), 5.03 (Death) or 5.05 (Without Cause)
hereof, Employer shall forgive fully and completely the principal amount of the
Loan and any accrued and unpaid interest thereon. In connection with any such
loan forgiveness provided for in this Section 3.09, Executive shall be
responsible for applicable withholding, FICA, Medicare, FUTA, SUTA and other
taxes, if any.

                                   TERMINATION

                                     GENERAL

     5.01. Employer and Executive shall have the right to terminate the
employment of Executive as set forth in this Article V.

                       INCAPACITY OF EXECUTIVE TO PERFORM

     5.02. If Executive shall become ill or be injured or otherwise become
incapacitated such that, in the good faith opinion of the Board of Directors, he
cannot carry out and perform fully his duties hereunder, and such incapacity
shall continue for a period of ninety (90) consecutive days, the Board of
Directors may, at any time after the ninety (90)-day period has passed, by
giving Executive written notice of such termination, fully and finally terminate
his employment under this Agreement. Termination under this Section 5.02 shall
be effective as of the date provided in such notice. In connection with the
termination of Executive pursuant to this Section 5.02, Employer shall pay to
Executive, in equal installments as set forth in Section 3.01, severance pay for
twelve (12) months or, if less than twelve (12) months remain in the Term of
this Agreement, an amount equal to his base salary for that number of the months
immediately preceding the termination that is equal to the number of months
remaining in the Term but in any event for not less than six (6) months;
provided, however, that such payments shall be reduced by the aggregate amount
of any payments Executive will be entitled to receive over the period from the
date of the termination of his employment hereunder through the end of the Term
of this Agreement under any long term disability insurance policy provided to
Executive by Employer. Upon such termination, Executive shall receive (i)
amounts payable pursuant to the terms of any applicable insurance policy or
similar arrangement that the Company maintains during the Term, (ii) payment for
any accrued but unused vacation days (the "Vacation Payment"), (iii) the unpaid
base salary to which the Executive is entitled pursuant to Section 3.01 and any
other compensation earned but not yet paid through the date of Executive's
termination (collectively, the "Compensation Payments"), and (iv) such


                                       5
<PAGE>   6


payments under applicable plans or programs, including but not limited to those
referred to in Article IV, to which the Executive is entitled pursuant to the
terms of such plans or programs. This Section 5.02 shall not limit the
entitlement of Executive or his beneficiaries to any benefits then available to
Executive under any stock option, restricted stock, Company loan, or other
benefit plan or policy that is maintained by the Company for the Executive's
benefit. The rights of Executive described in this paragraph shall be in
addition to and not to the exclusion of, the other remedies and termination
rights set forth in this Agreement.

                               DEATH OF EXECUTIVE

     5.03. The employment of Executive shall automatically terminate upon the
death of Executive. Upon such termination, Executive's estate or, if applicable,
his heirs shall receive (i) the Compensation Payments, (ii) the Vacation
Payment, and (iii) any death benefits under the employee benefit programs of the
Company. This Section 5.03 shall not limit the entitlement of the Executive's
estate or beneficiaries to any death or other benefits then available to the
Executive under any life insurance, stock option, restricted stock, Company
loan, or other benefit plan or policy that is maintained by the Company for the
Executive's benefit.

                              TERMINATION FOR CAUSE

     5.04. In addition to any other remedies that Employer may have at law or in
equity, the Board of Directors may terminate Executive's employment under this
Agreement by giving Executive written notice of such termination upon the Board
of Directors' determination that "Cause" therefor exists. "Cause" means that,
prior to any termination pursuant to Section 5.05, the Executive shall have:


     (i) been convicted of a criminal violation involving fraud, embezzlement or
     theft in connection with his duties or in the course of his employment with
     the Company; (ii) committed intentional wrongful damage to property of the
     Company; (iii) willfully and continuously failed to perform material
     assigned duties after written notice from the Board of Directors of such
     failure and Executive fails to cure such failure within a reasonable period
     after receipt of such notice, or (iv) committed intentional wrongful
     disclosure of secret processes or confidential information of the Company;

and any such act shall have been demonstrably and materially harmful to the
Company. Notwithstanding the foregoing, the Executive shall not be deemed to
have been terminated for "Cause" hereunder unless and until there shall have
been delivered to the Executive a copy of a resolution duly adopted by the
affirmative vote of not less than a majority of the Board of Directors then in
office at a meeting of the Board of Directors called and held for such purpose,
after reasonable notice to the Executive and an opportunity for the Executive,
together with the Executive's counsel (if the Executive chooses to have counsel
present at such meeting), to be heard before the Board of Directors, finding
that, in the good faith opinion of the Board of Directors, the Executive had
committed an act constituting "Cause" as herein defined and specifying the
particulars thereof in detail. Nothing herein will limit the right of the
Executive or his beneficiaries to contest the validity or propriety of any such
determination. Upon termination for Cause, Executive shall receive (a) the
Compensation Payments and (b) the Vacation Payment, and the Executive will be
entitled to no other compensation, except as otherwise due to him under
applicable law or the terms of any applicable plan or program.

                            TERMINATION WITHOUT CAUSE

     5.05. The Board of Directors may terminate Executive's employment under
this Agreement without any Cause whatsoever by giving Executive thirty (30)
days' written notice. If such termination is made pursuant to this Section 5.05,
Employer shall pay to Executive severance pay in an amount equal to the base
salary that would be payable to Executive over the period commencing on the date
of termination and ending twelve (12) months thereafter (the "Severance
Period"), assuming the base salary is the amount of Executive's base salary at
the time of the termination (or such greater amount previously in effect if
clause (iii) is applicable), which severance pay shall be paid to Executive
during the Severance Period in equal installments as set forth in Section 3.01.
For purposes of this Agreement, Executive's voluntary termination of employment
within sixty (60) days after the occurrence of any of the following events shall
be deemed a termination without Cause under this Section 5.05, (i) the reduction
in title of Executive from President and Chief Operating Officer of Employer,
(ii) a material adverse alteration or diminution in the nature or status of the
Executive's authority, duties or responsibilities from those in effect
immediately prior to such change, other than an isolated, insubstantial and
inadvertent action that is fully corrected within ten (10) days after receipt of
written notice from the Executive, (iii) a reduction in Executive's base
compensation, (iv) the failure to elect (as described in Section 2.01) or
reelect or otherwise to maintain the Executive as a Director of the Company or
(v) a material breach of this Agreement by the Employer. Upon termination
pursuant to this Section 5.05, Executive shall receive, in addition to the
amounts expressly provided by this Section 5.05, (i) the Compensation Payments
and (ii) the Vacation Payment, and the Executive will be entitled to no other
compensation, except as otherwise due to him under applicable law or the terms
of any applicable plan or program. This Section 5.05 shall not limit the
entitlement of Executive or his beneficiaries to any benefits then available to
Executive under any stock option, restricted stock, Company loan, or other
benefit plan or policy that is maintained by the Company for the Executive's
benefit. For the purpose of determining the period of continuation coverage to
which the Executive or any of his dependents is entitled under Section 4980B of
the internal Revenue Code of 1986, as amended (or any successor provision
thereto), under any group health plan maintained by the Company or its
affiliates, the Executive will be deemed to have remained employed until the end
of the Severance Period.

                            TERMINATION BY EXECUTIVE

     5.06. Executive may, with or without cause, terminate his employment under
this Agreement by giving Employer at least thirty (30) days' prior written
notice of such termination. Upon such termination, Executive shall receive (i)
the Compensation Payments and (ii) the Vacation Payment, and the Executive will
be entitled to no other compensation, except as otherwise due to him under
applicable law or the terms of any applicable plan or program. This Section 5.06
shall not apply to any termination of employment described by Section 5.05.

     The Company will promptly reimburse the Executive for all travel and other
business expenses that the Executive incurs in the course of the performance of

other person in so persuading or inducing, any person known by Executive to be a
customer of Employer within the States of Texas, Arizona, New Mexico, Oklahoma,
Louisiana and Arkansas (or in any other state(s) in which the Employer then owns
a switch or fiber or in which Employer has a material number of customers) to
give up, or to not commence, a business relationship with Employer.

                            NO CONFLICTING AGREEMENTS

     7.02. Except for the Undertaking with MCI Communications Corporation dated
August 31, 1998, the Separation Agreement dated October 11, 1996, with UniSite,
Inc. and the Second Amended and Restated Shareholders' Agreement dated December
18, 1997 with UniSite, Inc. and various shareholders thereof, copies of each of
which have been previously furnished by Executive to the Employer, Executive
represents and warrants to the Employer that Executive is not a party to any
agreement, contract or covenant: (i) limiting the freedom of Executive (or any
entity employing Executive) to compete in the business of the Employer or with
any person in any geographic area or restricting Executive or, by virtue of his
employment hereunder by the Employer, the Employer; or (ii) imposing upon
Executive or his employer any duty with respect to confidential or proprietary
information or with respect to the solicitation or hiring of any person.

                                     BREACH

     7.03. Executive hereby recognizes and acknowledges that irreparable injury
or damage shall result to the business of Employer in the event of a breach or
threatened breach by Executive of any of the terms or provisions of this Article
VII, and Executive therefore agrees that Employer shall be entitled to an
injunction restraining Executive from engaging in any activity constituting such
breach or threatened breach. Nothing contained herein shall be construed as
prohibiting Employer from pursuing any other remedies available to Employer at
law or in equity for such breach or threatened breach, including, but not
limited to, the recovery of damages from Executive and, if Executive is an
employee of the Employer, terminating the employment of Executive in accordance
with the terms and provisions of this Agreement.

is executed by Employer.
