                    PROXY STATEMENT OF CORAL SYSTEMS, INC.

                        PROSPECTUS OF LIGHTBRIDGE, INC.
    
     This Proxy Statement/Prospectus constitutes a proxy statement of Coral
Systems, Inc., a Delaware corporation ("Coral"), being furnished to the
stockholders of Coral in connection with the solicitation of proxies by the
Board of Directors of Coral for use at a Special Meeting of Stockholders of
Coral to be held at the offices of Cooley Godward LLP, 2595 Canyon Boulevard,
Suite 250, Boulder, Colorado on November 6, 1997 at 10 A.M. (local time) and at
any and all adjournments or postponements thereof (the "Special Meeting"). At
the Special Meeting, the stockholders of Coral will consider a proposal to
approve both (i) the Agreement and Plan of Reorganization dated as of September
9, 1997 (the "Reorganization Agreement") among Lightbridge, Inc., a Delaware
corporation ("Lightbridge"), SeeCross Acquisition Corp., a Delaware corporation
and wholly owned subsidiary of Lightbridge ("Acquisition Corp."), and Coral and
(ii) a merger pursuant to the Reorganization Agreement in which Acquisition
Corp. would merge with and into Coral and the surviving corporation would become
a wholly owned subsidiary of Lightbridge (the "Merger"). This Proxy
Statement/Prospectus and the accompanying form of proxy are first being mailed
to stockholders of Coral on or about October 9, 1997. CERTAIN CURRENT AND FORMER
DIRECTORS AND OTHER AFFILIATES OF CORAL HAVE PREVIOUSLY DELIVERED TO
REPRESENTATIVES OF LIGHTBRIDGE IRREVOCABLE PROXIES SUFFICIENT TO APPROVE THE
REORGANIZATION AGREEMENT AND THE MERGER.       
    
     This Proxy Statement/Prospectus also constitutes a prospectus of
Lightbridge with respect to shares of its common stock, $.01 par value
("Lightbridge Common"), proposed to be issued to Coral stockholders in
connection with the Merger. Lightbridge Common is traded on the Nasdaq National
Market under the symbol "LTBG." On October 6, 1997, the last reported sale price
per share of Lightbridge Common on the Nasdaq National Market was $15.875.      
    
     Pursuant to the Merger, each of the outstanding shares of Coral's common
stock, $.001 par value ("Coral Common"), Series A preferred stock, $.001 par
value ("Coral Series A"), Series B preferred stock, $.001 par value ("Coral
Series B"), and Series C preferred stock, $.001 par value ("Coral Series C"),
other than duly qualified dissenting shares, would convert into a fraction of a
share of Lightbridge Common determined as set forth in the Reorganization
Agreement, which determination will be (i) based in part on the average of the
last reported sale prices per share of Lightbridge Common on the Nasdaq National
Market over the ten trading days preceding the date on which Lightbridge
publicly announces its operating results for the quarter ended September 30,
1997 (the "Calculation Price") and (ii)subject to decrease as described herein
for certain expenses incurred by Coral in connection with the Merger and for
certain changes in the amount of working capital of Coral occuring prior to such
closing date (collectively, the "Adjustment Amount"). If the Calculation Price
is between $10.8375 and $14.6625, Lightbridge would issue (and reserve for
issuance upon exercise of outstanding Coral options and warrants) an aggregate
of 1,286,863 shares of Lightbridge Common, subject to decrease for the
Adjustment Amount. If the Calculation Price is less than $10.8375 or greater
than $14.6625, the aggregate number of shares of Lightbridge Common issued (and
reserved for issuance) would equal the quotient of $13,946,375 or $18,868,625,
respectively, in each case divided by the Calculation Price and subject to
decrease for the Adjustment Amount. See "The Merger Proposal--Calculation of
Merger Consideration." SHARES OF LIGHTBRIDGE COMMON ISSUABLE TO CORAL
STOCKHOLDERS IN CONNECTION WITH THE MERGER WILL BE SUBJECT TO SIGNIFICANT
INDEMNIFICATION AND ESCROW OBLIGATIONS AND WILL BE DELIVERED BETWEEN SIX AND
EIGHTEEN MONTHS AFTER THE CONSUMMATION OF THE MERGER. In addition, as a result
of the Merger, all options and warrants to purchase shares of Coral Common would
become exercisable, when vested, to purchase shares of Lightbridge Common.

     All information herein with respect to Lightbridge has been furnished by
Lightbridge, and all information herein with respect to Coral has been furnished
by Coral.  SEE "RISK FACTORS" BEGINNING AT PAGE 13 FOR A DISCUSSION OF CERTAIN
FACTORS THAT SHOULD BE CONSIDERED CAREFULLY BY CORAL STOCKHOLDERS IN EVALUATING
THE ACQUISITION OF THE SHARES OF LIGHTBRIDGE COMMON OFFERED HEREBY.

                                    SUMMARY

     The following summary is qualified in its entirety by the more detailed
information and financial statements and notes thereto appearing elsewhere in
this Proxy Statement/Prospectus and by the annexes hereto.  Each Coral
stockholder should read carefully the entire Proxy Statement/Prospectus,
including the annexes, before voting on the proposal discussed herein.

                                 THE COMPANIES

     LIGHTBRIDGE develops, markets and supports a network of integrated products
and services that enable wireless telecommunications carriers to improve their
customer acquisition and retention processes.  Lightbridge's comprehensive
software-based solutions are delivered primarily on an outsourcing and service
bureau basis, which allows wireless carriers to focus internal resources on
their core business activities.  Lightbridge's solutions combine the advantages
of distributed access and workflow management, centrally managed client-
specified business policies and links to carrier and third-party systems.  The
open architecture underlying Lightbridge's software applications supports the
development of flexible, integrated solutions, regardless of the type of
wireless service provided by a client and independent of the client's computing
environment.

     Lightbridge offers on-line, real-time transaction processing and call
center support solutions to aid carriers in qualifying and activating applicants
for wireless service, as well as software-based sales support services for
traditional distribution channels, such as dealers, agents and direct mobile
sales forces, and emerging distribution channels, such as mass market retail
stores, home shopping and stand-alone kiosks. Lightbridge develops and
implements interfaces that fully integrate its acquisition system with carrier
and third-party systems, such as those for billing, point-of-sale, activation
and order fulfillment. Lightbridge recently introduced software-based decision
support tools and services that enable carriers to reduce subscriber churn and
to make more informed business decisions about their subscribers, markets and
distribution channels.

     Lightbridge was incorporated in Delaware in June 1989.  Lightbridge's
principal executive offices are located at 67 South Bedford Street, Burlington,
Massachusetts 01803, and its telephone number is (781) 359-4000.

    
     ACQUISITION CORP. was incorporated in Delaware in September 1997 for the
purpose of effecting the Merger.  Acquisition Corp. is a wholly owned subsidiary
of Lightbridge, and it has no material assets and has not engaged in any
activities except in connection with the proposed Merger.  Acquisition Corp.'s
principal executive offices are located at the same address, and it has the same
telephone number, as Lightbridge.       

     CORAL provides client-server software products for the wireless
telecommunications industry to enable carriers to reduce fraud and customer
turnover, or "churn," and increase operating efficiencies. Coral's products are
based upon its core technology, which provides several key advantages, including
rapid product development, portability, technology independence and enhanced
scalability. Coral's fraud management software, FraudBuster, incorporates a
fraud profiler and subscription fraud monitoring functionality and is designed
to combat most currently identified types of wireless fraud. Unlike many other
fraud prevention techniques, which address specific types of fraud, FraudBuster
detects multiple types of existing and emerging fraud, including cloning,
subscription fraud, tumbling fraud and cellular telephone theft. Coral's churn
prevention product, ChurnAlert, allows carriers to analyze and identify
potential churn candidates before they seek customer service assistance or
deactivate service.

     Coral was incorporated in Colorado in August 1991 and reincorporated in
Delaware in April 1995.  Coral's executive offices are located at 1500 Kansas
Avenue, Suite 2E, Longmont, Colorado 80501, and its telephone number is (303)
772-5800.

                                SPECIAL MEETING

     TIME, PLACE AND DATE.  The Special Meeting will be held on November 6, 
1997 at 10 A.M. (local time) at the offices of Cooley Godward LLP, 2595 Canyon
Boulevard, Suite 250, Boulder, Colorado. 

     PURPOSE OF THE SPECIAL MEETING. At the Special Meeting, the stockholders of
Coral will consider and vote upon a single proposal to approve the
Reorganization Agreement and the Merger (the "Merger Proposal"). THE BOARD OF
DIRECTORS OF CORAL HAS UNANIMOUSLY APPROVED THE REORGANIZATION AGREEMENT AND THE
MERGER AND UNANIMOUSLY RECOMMENDS THAT CORAL STOCKHOLDERS VOTE FOR THE MERGER
PROPOSAL. See "The Merger Proposal--Background of the Merger," "--Coral's
Reasons for the Merger; Recommendation of the Board of Directors of Coral" and
"--Interests of Certain Persons in the Merger."

     VOTES REQUIRED; RECORD DATE. The close of business on October 8, 1997
has been fixed as the record date for the determination of Coral stockholders
entitled to notice of and to vote at the Special Meeting, including at any
adjournment or postponement thereof (the "Record Date"). The presence, in person
or by proxy, of the holders of one-third of the outstanding shares of Coral
Common and of holders of one-third of the outstanding shares of Coral Series A,
Coral Series B and Coral Series C (on an as-converted basis) will constitute a
quorum at the Special Meeting. Abstentions will be included as present or
represented for purposes of establishing a quorum for the transaction of
business. 

     Under Coral's Amended and Restated Certificate of Incorporation, as amended
(the "Coral Charter"), approval of the Merger Proposal requires both (i) the
affirmative vote of the holders of a majority of the outstanding shares of Coral
Common entitled to vote at the Special Meeting and (ii) the affirmative vote of
the holders of a majority of the outstanding Coral Series A, Coral Series B and
Coral Series C, voting as a single class on an as-converted basis, entitled to
vote at the Special Meeting. As of the Record Date, there are expected to be 
issued and outstanding 3,276,134 shares of Coral Common, entitling each holder
thereof to one vote. In addition, there are expected to be issued and
outstanding 2,000,000 shares of Coral Series A, 2,083,333 shares of Coral Series
B and 1,824,920 shares of Coral Series C, each of which would entitle the holder
thereof (on an as-converted basis) to one-half vote, one vote and one-half vote,
respectively. 

     CERTAIN CURRENT AND FORMER DIRECTORS AND OTHER AFFILIATES OF CORAL, WHO
HOLD IN THE AGGREGATE A MAJORITY OF THE OUTSTANDING SHARES OF CORAL COMMON AND A
MAJORITY OF THE OUTSTANDING SHARES OF CORAL SERIES A, CORAL SERIES B AND CORAL
SERIES C (ON AN AS-CONVERTED BASIS), HAVE EXECUTED VOTING AGREEMENTS WITH
LIGHTBRIDGE PURSUANT TO WHICH THEY HAVE AGREED TO VOTE IN FAVOR OF THE MERGER
PROPOSAL AND HAVE DELIVERED TO LIGHTBRIDGE IRREVOCABLE LIMITED PROXIES WITH
RESPECT TO THE MERGER PROPOSAL. ACCORDINGLY, THOSE VOTING AGREEMENTS AND
IRREVOCABLE LIMITED PROXIES ARE SUFFICIENT TO EFFECT THE APPROVAL OF THE MERGER
PROPOSAL. See "Other Agreements--Voting Agreements."
                                                                                
     CHANGE OF VOTE.  Holders of shares of Coral Common, Coral Series A, Coral
Series B and Coral Series C (collectively, "Coral Capital Stock") who execute a
proxy in the enclosed form may revoke the proxy at any time before it is
exercised by (i) delivering to the Secretary of Coral at Coral's headquarters,
1500 Kansas Avenue, Suite 2E, Longmont, Colorado 80501, a written notice of
revocation prior to the voting of the proxy at the Special Meeting, (ii) signing
and returning a later dated proxy to the Secretary of Coral prior to the Special
Meeting, or (iii) attending the Special Meeting and informing the Secretary of
Coral in writing that such holder wishes to vote the shares in person.
Accordingly, stockholders of Coral who execute and return proxy cards in advance
of the Special Meeting may change their votes at any time prior to or at the
Special Meeting.  The foregoing revocation procedures do not apply to directors
and other affiliates of Coral who have executed voting agreements with
Lightbridge, as described in the preceding paragraph.

                                  THE MERGER

     THE MERGER. Pursuant to the Reorganization Agreement, Acquisition Corp.
will be merged with and into Coral and the surviving corporation, which will be
known as Coral Systems, Inc., will become a wholly owned subsidiary of
Lightbridge (the "Surviving Corporation"). See "The Merger Proposal."
    
     MERGER CONSIDERATION. Pursuant to the Merger, each of the outstanding
shares of Coral Capital Stock, other than any duly qualified dissenting share,
would convert into a fraction of a share of Lightbridge Common determined as set
forth in the Reorganization Agreement, which determination will be (i) based in
part on the Calculation Price and (ii) subject to decrease for the Adjustment
Amount. If the Calculation Price is between $10.8375 and $14.6625, Lightbridge
would issue (and reserve for issuance upon exercise of outstanding Coral options
and warrants) an aggregate of 1,286,863 shares of Lightbridge Common, subject to
decrease for the Adjustment Amount. If the Calculation Price is less than
$10.8375 or greater than $14.6625, the aggregate number of shares of Lightbridge
Common issued (or reserved for issuance) would equal the quotient of $13,946,375
or $18,868,625, respectively, divided by the Calculation Price, in each case
subject to decrease for the Adjustment Amount. See "The Merger Proposal--
Calculation of Merger Consideration."     
    
     ESCROW AND RELEASE OF SHARES. Upon consummation of the Merger, each holder
of Coral Capital Stock would be entitled to receive approximately one-third of
the shares of Lightbridge Common into which those shares of Coral Capital Stock
converted. Such shares will be delivered to the Exchange Agent (as defined
below) for delivery to the former Coral stockholders approximately six months
after the closing of the Merger. The balance of the shares of Lightbridge Common
would be held in escrow by American Stock Transfer & Trust Company, as escrow
agent (the "Escrow Agent"), in support of the indemnification obligations of the
Coral stockholders under the Reorganization Agreement and the escrow agreement
(the "Escrow Agreement") to be entered into as of the date of the closing under
the Reorganization Agreement (the "Closing"). See "The Reorganization 
Agreement--Indemnification" and "Other Agreements--Escrow Agreement." Subject to
the resolution of unsatisfied claims of Lightbridge, (i) one-half of the
escrowed shares, less any shares canceled in satisfaction of indemnified claims,
would be released from escrow one year after the Effective Time and (ii) any
balance of escrowed shares would be released from escrow eighteen months after
the Effective Time.     

     BY APPROVING THE REORGANIZATION AGREEMENT, CORAL STOCKHOLDERS WILL BE
DEEMED TO HAVE CONSENTED TO THE APPOINTMENT OF R.D. "PETE" BLOOMER, A
STOCKHOLDER AND FORMER DIRECTOR OF CORAL, TO ACT AS THE "HOLDERS' AGENT" ON
BEHALF OF CORAL STOCKHOLDERS IN CONNECTION WITH THE DETERMINATION OF THE
ADJUSTMENT AMOUNT, THE INDEMNIFICATION OBLIGATIONS OF THE CORAL STOCKHOLDERS
UNDER THE REORGANIZATION AGREEMENT, AND THE DEPOSIT AND RELEASE OF SHARES
PURSUANT TO THE REORGANIZATION AGREEMENT AND THE ESCROW AGREEMENT.
    
     EXCHANGE OF CERTIFICATES. As soon as reasonably practicable after the
Effective Time, and upon each release of Lightbridge Common in accordance with
the terms of the escrow arrangements, American Stock Transfer & Trust Company,
in its capacity as exchange agent for the Merger (the "Exchange Agent"), will
send to each Coral stockholder a letter of transmittal and instructions to
effect the surrender of certificates representing shares of Coral Capital Stock,
in exchange for certificates representing shares of Lightbridge Common. Coral
stockholders, however, will not receive any shares of Lightbridge Common until
approximately six months following the closing of the Merger, when approximately
one-third of Lightbridge Common issuable to them in respect of the Merger will
be delivered by the Exchange Agent. See "The Merger Proposal--Conversion of
Shares; Procedures for Exchange of Certificates." CORAL STOCKHOLDERS SHOULD NOT
RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY AND SHOULD NOT FORWARD THEIR
CERTIFICATES TO THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS.

     CONDITIONS TO THE MERGER. The consummation of the Merger is subject to 
various conditions, including approval of the Merger Proposal by the 
stockholders of Coral, the absence of any legal restraints or prohibitions 
preventing the consummation of the Merger, the absence of any material adverse 
changes in the business of Coral or Lightbridge, and other customary conditions.
See "The Reorganization Agreement--Conditions to the Merger."

     TERMINATION. The Reorganization Agreement may be terminated at any time 
prior to the Closing: (i) by mutual written consent of Coral and Lightbridge
(ii) by Coral or Lightbridge if the stockholders of Coral vote not to approve
the Merger Proposal; (iii) by Coral or Lightbridge if the Closing does not occur
on or before December 31, 1997; (iv) by Coral or Lightbridge if (a) there has
been a final nonappealable order of a federal or state court in effect
preventing consummation of the transactions contemplated by the Reorganization
Agreement or (b) there has been any action taken, or any statute, rule,
regulation or order erected, promulgated or issued or deemed applicable to the
transactions contemplated by the Reorganization Agreement by any governmental
entity that would make consummation of the transactions contemplated by the
Reorganization Agreement illegal; (v) by Coral if there has been a material
breach of any representation, warranty, covenant or agreement contained in the
Reorganization Agreement on the part of Lightbridge or Acquisition Corp. and, if
such breach is curable, such breach has not been promptly cured after written
notice of such breach; (vi) by Lightbridge if there has been a material breach
of any representation, warranty, covenant or agreement contained in the
Reorganization Agreement on the part of Coral and, if such breach is curable,
such breach has not been promptly cured after written notice of such breach;
(vii) by Lightbridge if there shall be any action taken, or any statute, rule,
regulation or order enacted, promulgated or issued or deemed applicable to the
transactions contemplated by the Reorganization Agreement by any governmental
entity that would (a) prohibit Lightbridge's or Coral's ownership or operation
of all or a material portion of the business or assets of Coral or Lightbridge
and its subsidiaries taken as a whole, or compel Lightbridge or Coral to dispose
of or hold separate all or a material portion of the business or assets of Coral
or Lightbridge, as a result of the transactions contemplated by the
Reorganization Agreement or (b) render Lightbridge or Coral unable to consummate
the transactions contemplated by the Reorganization Agreement; (viii) by
Lightbridge if any condition to the obligation of Lightbridge and Acquisition
Corp. to complete the transactions contemplated by the Reorganization Agreement
has not been satisfied by Coral or waived by Lightbridge; (ix) by Coral if any
condition to the obligation of Coral to complete the transactions contemplated
by the Reorganization Agreement has not been satisfied by Lightbridge or
Acquisition Corp. or waived by Coral; (x) by Lightbridge if the Calculation
Price is less than $9.5625; or (xi) by Coral if (a) the Calculation Price is
less than $9.5625 and, following the date of the Reorganization Agreement, an
event has occurred that has had a material adverse effect on the business,
financial condition or results of operations of Lightbridge or (b) the
Calculation Price is more than $15.9375. CORAL STOCKHOLDER APPROVAL OF THE
MERGER PROPOSAL WILL CONFER UPON THE BOARD OF DIRECTORS OF CORAL THE POWER,
CONSISTENT WITH ITS FIDUCIARY DUTIES, TO CONSUMMATE THE MERGER IN THE EVENT THAT
THE CALCULATION PRICE OF THE LIGHTBRIDGE COMMON IS LESS THAN $9.5625 OR MORE
THAN $15.9375. See "The Reorganization Agreement--Termination."

     NASDAQ LISTING. Lightbridge will use its reasonable efforts to cause all of
the shares of Lightbridge Common issuable in the Merger, or upon exercise of
Coral options and warrants outstanding as of the Effective Time, to be approved
for quotation on the Nasdaq National Market. See "The Merger Proposal--Nasdaq
Listing."

     APPRAISAL RIGHTS.  Any holder of shares of Coral Capital Stock as of the
Record Date who elects to dissent from the approval of the Merger Proposal and
who follows the procedures set forth in Section 262 of the Delaware General
Corporation Law ("Delaware Law"), will be entitled, as an alternative to
receiving Lightbridge Common in exchange for those shares of Coral Capital
Stock, to a judicial determination of the fair value in cash of those shares. A
copy of Section 262 of the Delaware Law is attached as ANNEX B to this Proxy
Statement/Prospectus.  See "The Merger Proposal--Appraisal Rights."

OPTIONS AND WARRANTS.  Each outstanding option to purchase shares of Coral
Common previously issued under Coral's Amended and Restated Stock Option Plan
(each an "Option" and collectively the "Options") and each outstanding
warrant of Coral to purchase shares of Coral Common (each a "Warrant" and
collectively the "Warrants"), whether vested or unvested, would entitle its
holder, upon exercise (if and when vested) following the Effective Time, to
receive that number of whole shares of Lightbridge Common equal to the product
of the number of shares of Coral Common that were issuable upon exercise of such
Option or Warrant immediately prior to the Effective Time (without regard to
vesting) multiplied by the conversion rate for a single share of Coral Common,
rounded down to the nearest whole number of shares of Lightbridge Common.  In
addition, following the Effective Time, the per share exercise price for the
Lightbridge Common issuable upon exercise of each Option and Warrant
would be equal to the per share exercise price thereof immediately prior to the
Effective Time divided by the conversion rate for a single share of Coral
Common.  See "The Merger Proposal--Calculation of Merger Consideration."
    
     MARKET PRICE DATA. Lightbridge Common is traded on the Nasdaq National
Market under the symbol "LTBG." The last sale price per share of Lightbridge
Common was $14.75 on September 9, 1997, the day that the Reorganization
Agreement was signed and the last trading day preceding the public announcement
of the proposed Merger, and was $15.875 on October 6, 1997, the last trading day
preceding the date of this Proxy Statement/Prospectus. Because there is no
established trading market for any class of Coral Capital Stock, information
with respect to the market price thereof on an historical and equivalent per
share basis has been omitted.

                  INTERESTS OF CERTAIN PERSONS IN THE MERGER
    
     As of October 1, 1997, the directors and executive officers of Coral as a
group beneficially owned an aggregate of 837,542 shares of Coral Common
(including shares purchasable upon the exercise of outstanding Options and
Warrants within 60 days of September 1, 1997), 125,000 shares of Coral Series A
and 522,500 shares of Coral Series B.  All of those shares will be treated in
the Merger in the same manner as the shares of Coral stock held by other
stockholders of Coral.  Certain current and former directors and other
affiliates of Coral, who hold in the aggregate a majority of the outstanding
Coral Common and a majority of the outstanding Coral Series A, Coral Series B
and Coral Series C (on an as-converted basis), have executed voting agreements
with Lightbridge pursuant to which they have agreed to vote in favor of the
Merger Proposal and have delivered to Lightbridge irrevocable limited proxies
with respect to the Merger Proposal.  Accordingly, those voting agreements and
irrevocable limited proxies are sufficient to approve the Merger Proposal.  See
"Other Agreements--Voting Agreements" and "Principal Stockholders of Coral."  To
the best of Coral's knowledge, each of the other Coral directors and executive
officers who owns shares of Coral stock intends to vote those shares in favor of
the Merger Proposal.       

     On September 8, 1997, the Board of Directors of Coral adopted a Management
Bonus Plan pursuant to which five of Coral's key employees will receive staying
bonuses in an aggregate amount of $220,000 for their continued employment with
Coral through the Closing. The Management Bonus Plan was adopted to provide an
incentive to those key employees whom the Board of Directors of Coral determined
to be integral to the consummation of the Merger. The bonuses will be payable
within ten days of the Closing.

     Pursuant to the Reorganization Agreement, two of Coral's executive officers
will enter into employment agreements with Coral providing for their continued
employment with Coral.

     Persons identified by Coral as "affiliates" (as that term is defined for
purposes of Rule 145 under the Securities Act) of Coral will enter into
agreements restricting sales, dispositions or other transactions reducing their
risk of investment with respect to shares of Coral Capital Stock held by them
prior to the Merger and the shares of Lightbridge Common received by them in the
Merger so as to comply with the requirements of applicable federal securities
laws.

     See "The Merger Proposal--Interests of Certain Persons in the Merger."

                                   EXPENSES
    
     In the event the Merger is completed, (a) Lightbridge and Acquisition Corp.
will be and remain responsible for their costs and expenses and (b) the Coral
stockholders will be and remain responsible for their costs and expenses, as
well as the costs and expenses of Coral arising prior to the Closing in
connection with the Merger, except that Lightbridge will be responsible for (i)
a total of $500,000 of fees of Coral's financial advisor, Broadview Associates
LLC ("Broadview"), incurred by Coral in connection with the Merger and (ii) a
total of $220,000 payable to five of Coral's key employees under the Management
Bonus Plan described in "The Merger Proposal--Interests of Certain Persons in
the Merger." Any obligations of the Coral stockholders described in clause (b)
above shall be part of the Adjustment Amount and shall be deemed to be paid by a
decrease in the number of shares of Lightbridge Common otherwise issuable in
connection with the Merger. See "The Merger Proposal--Calculation of Merger
Consideration."     

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
    
     The Merger is intended to be a tax-free reorganization so that no gain or
loss will be recognized by Coral stockholders for federal income tax purposes,
except for holders of dissenting shares. The qualification of the Merger as a
reorganization, however, depends on a number of factual matters, and accordingly
no assurance can be given that the Merger will qualify as a tax-free
reorganization for federal income tax purposes. See "The Merger Proposal--
Certain Federal Income Tax Considerations."      

  RESTRICTION ON RESALE OF SHARES OF LIGHTBRIDGE COMMON ISSUED IN THE MERGER
    
     Shares of Lightbridge Common issued in the Merger will be, when delivered
to Coral stockholders in accordance with the Reorganization Agreement and the
Escrow Agreement, freely transferable, except for shares issued to persons who
are "affiliates" of Lightbridge or Coral, which shares will be subject to
certain restrictions on resale under Rule 145 promulgated under the Securities
Act. See "The Merger Proposal--Federal Securities Law Consequences."

                          COMPARATIVE PER SHARE DATA
    
     The following table sets forth certain historical per share data of
Lightbridge and Coral and unaudited pro forma consolidated condensed per share
data based upon the assumptions that (i) the Merger was consummated as of
January 1, 1996, (ii) the Merger was accounted for as a purchase and (iii) each
outstanding share of Coral Common, Coral Series A, Coral Series B and Coral
Series C was converted into .0682, .0755, .1609 and .1563 shares of Lightbridge
Common, respectively. The actual numbers of shares of Lightbridge Common that
will be issued upon conversion of outstanding shares of each class of Coral
Capital Stock will be determined in part by the Calculation Price and in part by
the amount of the Adjustment Amount. These conversion ratios assume that the
Calculation Price will be $16.175, as if the Closing were held on September 26,
1997 (the latest practicable date before the initial filing of this Proxy
Statement/Prospectus with the Commission), and that the Adjustment Amount will
be $400,000, consisting principally of legal and accounting fees and other
expenses expected to be incurred by Coral and paid by Lightbridge in connection
with the Merger. THE ACTUAL CONVERSION RATES APPLICABLE TO CORAL CAPITAL STOCK
MAY DIFFER MATERIALLY FROM THESE PRELIMINARY ESTIMATES. See "The Merger 
Proposal--Calculation of Merger Consideration" and "Lightbridge, Inc. Unaudited
Pro Forma Condensed Consolidated Balance Sheet and Statements of Operations."
The unaudited pro forma consolidated condensed per share data are not
necessarily indicative of the operating results that would have been achieved
had the Merger been consummated as of January 1, 1996 and should not be
construed as representative of future operations. The following data should be
read in conjunction with "Selected Consolidated Financial Data of Lightbridge,"
"Selected Financial Data of Coral," "Unaudited Pro Forma Condensed Consolidated
Balance Sheet and Statements of Operations of Lightbridge" and the separate
historical financial statements of Lightbridge and Coral included elsewhere in
this Proxy Statement/Prospectus.     

     Neither Lightbridge nor Coral has ever declared or paid any cash dividends
on shares of its capital stock.

                                 RISK FACTORS

     In addition to the other information presented in this Proxy
Statement/Prospectus, the following risk factors should be considered carefully
in evaluating the Merger Proposal and the resulting acquisition of the shares of
Lightbridge Common offered hereby. For periods following the Merger, references
to the products, business, operations, financial results or financial condition
of Lightbridge should be considered to refer to Lightbridge and Coral, unless
the context otherwise requires.

     DEPENDENCE ON LIMITED NUMBER OF CLIENTS. A limited number of clients
historically have accounted for a substantial portion of Lightbridge's revenues
in each fiscal year. Revenues attributable to Lightbridge's 10 largest clients
accounted for approximately 90%, 90% and 81% of Lightbridge's total revenues in
the years ended September 30, 1994 and 1995 and December 31, 1996, respectively.
During the years ended September 30, 1994 and 1995, each of Lightbridge's four
largest clients, and during the year ended December 31, 1996 each of
Lightbridge's two largest clients, accounted for more than 10% of Lightbridge's
total revenues, representing an aggregate of 64%, 63% and 44% of total revenues
in those periods, respectively. GTE Mobile Communications Service Corporation
("GTE Mobile"), which accounted for 31% and 15% of Lightbridge's revenues in the
years ended September 30, 1995 and December 31, 1996, respectively, changed the
way it accessed Lightbridge's Customer Acquisition System during the year ended
December 31, 1996, and then terminated its client relationship with Lightbridge
as of June 30, 1997. As a result, Lightbridge's revenues from GTE Mobile
decreased significantly during the year ended December 31, 1996 and the first
half of 1997, before being curtailed completely as of June 30, 1997. The
concentration of Lightbridge's revenues can cause Lightbridge's revenues and
earnings to fluctuate significantly from quarter to quarter, based on the volume
of qualification and activation transactions generated through its significant
clients. Moreover, recent consolidation among established participants in the
wireless telecommunications industry may result in further concentration of
Lightbridge's revenues from a limited number of clients. Lightbridge expects
that revenues attributable to a relatively small number of clients will continue
to represent a significant percentage of its total revenues for the foreseeable
future. Lightbridge's contracts with its clients generally extend for terms of
one or more years and do not typically require the clients to purchase any
particular type or quantity of Lightbridge's products or services or to pay any
minimum amount for products or services. Therefore, there can be no assurance
that any of Lightbridge's clients, including its significant clients, will
continue to utilize Lightbridge's services at levels similar to previous years
or at all. The loss of, or a significant curtailment of purchases by, one or
more of Lightbridge's significant clients, including a loss or curtailment due
to factors outside of Lightbridge's control, could have a material adverse
effect on Lightbridge's business, financial condition, results of operations and
cash flow. In addition, delays in collection or uncollectability of accounts
receivable from any of Lightbridge's significant clients could have a material
adverse effect on Lightbridge's liquidity and working capital position. See
"Lightbridge Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business of Lightbridge-- Clients."

     INTEGRATION OF CORAL INTO LIGHTBRIDGE.  The Merger involves the combination
of two companies that have previously operated independently.  The achievement
of the anticipated benefits of the Merger will involve significant integration
of the two companies' businesses, and no assurance can be given that the
integration will be achieved in an efficient and effective manner.  The
integration of the companies's businesses will require that Lightbridge, among
other things, integrate the companies' software products and technologies,
retain key Coral employees, assimilate diverse corporate cultures, integrate the
companies' management information systems, consolidate Coral's operations, and
manage the companies' geographically dispersed operations, each of which could
pose significant challenges.  The difficulty of combining the companies may be
increased by the need to integrate personnel, and changes effected in the
combination may cause key employees to leave.  The diversion of the attention of
management created by the integration process, and any disruptions or other
difficulties encountered in the transition process, could temporarily distract
attention from the day-to-day business of Lightbridge.  There can be no
assurance that Lightbridge will be able to integrate the operations of Coral
successfully, and any failure to do so could have a material adverse effect on
Lightbridge's business, financial condition, results of operations and cash
flow. Furthermore, Lightbridge's issuance of shares of Lightbridge Common, its
write-off of in-process research and development expenses, and its amortization
of goodwill and acquired technology in connection with the Merger will have the
effect of reducing Lightbridge's earnings per

                                       13
<PAGE>
 
share and may reduce the market price of Lightbridge Common unless and until
revenue growth or cost savings and other business synergies sufficient to offset
the effect of such issuance can be achieved. There can be no assurance that such
cost savings or other synergies will be achieved. See "The Merger Proposal--
Background of the Merger."
    
     PARTIALLY FIXED CONVERSION RATIO DESPITE POTENTIAL CHANGES IN STOCK PRICES.
The respective ratios at which the Coral Common, Coral Series A, Coral Series B
and Coral Series C will be converted into Lightbridge Common are fixed within a
range of Calculation Prices, and within that range, those ratios will not be
adjusted in the event of any increases or decreases in the market price of
Lightbridge Common.  Even if the Calculation Price falls outside of that range,
the number of shares of Lightbridge Common to be issued (and reserved for
issuance upon subsequent exercises of outstanding Options and Warrants) in
connection with the Merger will be adjusted only to the extent necessary to
cause the aggregate value of the issued (and reserved for issuance) shares of
Lightbridge Common to equal the aggregate value of Lightbridge Common that would
have been issued (and reserved for issuance) if the Calculation Price were at
the top or bottom of the range. As a result, if the Calculation Price is less
than $10.8375, the aggregate number of shares of Lightbridge Common issued (and
reserved for issuance) would be equal to the quotient of $13,946,375 divided by
the Calculation Price, subject to adjustment for the Adjustment Amount; while
the number of shares of Lightbridge Common would be increased to the extent the
Calculation Price is less than $10.8375, the aggregate value of the shares,
based on the Calculation Price, would be limited to $13,946,375. Alternatively,
if the Calculation Price is greater than $14.6625, the aggregate number of
shares of Lightbridge Common issued (and reserved for issuance) would be equal
to the quotient of $18,868,625 divided by the Calculation Price, subject to
adjustment for the Adjustment Amount; the aggregate number of shares of
Lightbridge Common would be decreased to the extent the Calculation Price is
greater than $14.6625. The market price of Lightbridge Common at the Effective
Time may vary from its price on the date of this Proxy Statement/Prospectus and
on the date of the Special Meeting. Such variation may be the result of changes
in the business, operations or prospects of Lightbridge, the timing of the
Merger, the prospects of the Merger and post-Merger operations, regulatory
considerations, general market and economic conditions, and other factors.
Stockholders of Coral are urged to obtain current market quotations for
Lightbridge Common. See "The Merger Proposal--Calculation of the Merger
Consideration."     

     FLUCTUATIONS IN QUARTERLY PERFORMANCE MAY ADVERSELY AFFECT MARKET PRICE OF
LIGHTBRIDGE COMMON.  Lightbridge has experienced fluctuations in its quarterly
operating results and anticipates that such fluctuations will continue and could
intensify.  Lightbridge's quarterly operating results may vary significantly
depending on a number of factors, including the timing of the introduction or
acceptance of new products and services offered by Lightbridge or its
competitors, changes in the mix of products and services provided by
Lightbridge, the nature and timing of changes in Lightbridge's clients or their
use of Lightbridge's products and services, consolidation among participants and
other changes in the wireless telecommunications industry, changes in the client
markets served by Lightbridge, changes in regulations affecting the wireless
industry, changes in Lightbridge's operating expenses, changes in personnel and
changes in general economic conditions.  Historically, Lightbridge's quarterly
revenues have been highest in the fourth quarter of each calendar year and have
been particularly concentrated in the holiday shopping season between
Thanksgiving and Christmas.  Lightbridge's transaction revenues, which
historically have represented the majority of Lightbridge's total revenues, are
affected by the volume of use of Lightbridge's services, which is influenced by
seasonal and retail trends, the success of the carriers utilizing Lightbridge's
services in attracting subscribers and the markets served by Lightbridge for its
clients.  Software and consulting revenues, which include software license
revenues and related consulting revenues, have recently represented an
increasing proportion of Lightbridge's total revenues.  Software license
revenues are principally recognized at the time the licensed products are
delivered and significant obligations are completed, and therefore may result in
further fluctuations in Lightbridge's quarterly operating results.  Consulting
revenues may be influenced by the requirements of one or more of Lightbridge's
significant clients, including engagement of Lightbridge for implementing or
assisting in implementing special projects of limited duration.  There can be no
assurance that Lightbridge will be able to achieve or maintain profitability in
the future or that its levels of profitability will not vary significantly among
quarterly periods.  Fluctuations in operating results may result in volatility
in the market price of Lightbridge Common.

     Although Lightbridge's existing clients typically provide forecasts of
future activity levels, these forecasts have not always proved accurate. In
addition, the sales cycles for Lightbridge's services are typically lengthy and
subject to a number of significant risks over which Lightbridge has little or no
control, including clients' budget constraints and internal authorization
reviews. As a result, Lightbridge may not be able to make accurate estimates of
future sales levels. A significant portion of Lightbridge's expenses are fixed
and difficult to reduce in the event revenues do not meet Lightbridge's
expectations, thus magnifying the adverse effect of any revenue shortfall.
Furthermore, announcements by Lightbridge or its competitors of new products,
services or technologies could cause clients to defer or cancel purchases of
Lightbridge's products and services; any such deferral or cancellation could
have a material adverse effect on Lightbridge's business, financial condition,
results of operations and cash flow. Accordingly, revenue shortfalls can cause
significant variations in operating results from quarter to quarter and could
have a material adverse effect on Lightbridge's results of operations. If demand
for Lightbridge's services significantly exceeds Lightbridge's estimates at a
time when its systems are used at or near capacity, however, Lightbridge may be
unable to meet contractually required service levels. Lightbridge's failure to
meet such service levels could permit clients to terminate their agreements with
Lightbridge or give rise to liability for damages or penalties, either of which
could have a material adverse effect on Lightbridge's business, financial
condition, results of operations and cash flow. In addition, Lightbridge has
hired a significant number of employees since January 1995 and this significant
increase in its workforce may negatively impact Lightbridge's operating margins
in the future, particularly if Lightbridge's commercial introduction of new
products and services is not as successful as planned.

     Due to all of the foregoing factors, it is possible that in some future
quarter Lightbridge's results of operations will be below prior results or the
expectations of market analysts and investors.  In such an event, the market
price of Lightbridge Common would likely be materially adversely affected.
    
     INCURRENCE OF SIGNIFICANT TRANSACTION CHARGES. Lightbridge expects to incur
charges to operations currently estimated to be between $17.0 million and $18.0
million in the quarter ending December 31, 1997, the quarter in which the Merger
is expected to be consummated, to reflect the write-off of in-process research
and development, the amortization of goodwill and acquired technology, and costs
associated with combining the operations of the two companies. This amount is a
preliminary estimate and is therefore subject to change. Additional
unanticipated expenses may be incurred relating to the integration of the
businesses of Lightbridge and Coral. Although Lightbridge expects that the
elimination of duplicative expenses as well as other efficiencies related to the
integration of the business of Coral may offset additional expenses over time,
there can be no assurance that such net benefit will be achieved in the near
term or at all.     

     HISTORY OF LOSSES; CAPITAL REQUIREMENTS. Lightbridge was founded in 1989
and has incurred net losses in each of its fiscal years other than the years
ended September 30, 1994 and December 31, 1996. No assurance can be given that
Lightbridge will be profitable on either a quarterly or annual basis in the
future or that Lightbridge will not need to raise funds through public or
private financings. Moreover, no assurance can be given that Coral will be
profitable on either a quarterly or annual basis in the future or that
Lightbridge will not need to raise additional funds to support the operations of
Coral. Further expansion of Lightbridge's business, including the acquisition of
additional computer and network equipment and the expansion of its teleservices
call center capacity, will require Lightbridge to make significant capital
expenditures. Lightbridge believes that the net proceeds of its initial public
offering received in October 1996, together with existing cash balances and
funds available under existing lines of credit, will be sufficient to finance
Lightbridge's operations and capital expenditures through at least the next
twelve months. In the event that Lightbridge's plans change or available cash
resources otherwise prove to be insufficient (due to unanticipated expenses or
otherwise), Lightbridge may be required to seek additional financing or curtail
its expansion activities. Lightbridge may determine, depending upon the
opportunities available to it, to seek additional debt or equity financing to
fund the cost of continuing expansion. To the extent that Lightbridge obtains
equity financing or finances an acquisition with equity securities, any such
issuance of equity securities could result in dilution to the interests of
Lightbridge's stockholders. There can be no assurance that additional financing
will be available to Lightbridge on acceptable terms, or at all. See
"Lightbridge Management's Discussion and Analysis of Financial Condition and
Results of Operations."

     RAPID INDUSTRY CHANGE REQUIRES ONGOING PRODUCT DEVELOPMENT EFFORTS. The
wireless telecommunications industry has been changing rapidly as a result of
increasing competition, technological advances and evolving industry practices
and standards, and Lightbridge expects these changes to continue. Carriers in
the wireless market have also been changing quickly, as the result of
consolidation amoung established carriers and the rapid entrance of new carriers
into the market. Lightbridge's future success will depend on the continued use
of its existing products and services, market acceptance of its new products and
services and Lightbridge's ability to develop and market new offerings or adapt
existing offerings to keep pace with changes in the wireless telecommunications
industry. A rapid shift away from the use of cellular in favor of other
telecommunications services could affect demand for Lightbridge's product and
service offerings, since different business practices might evolve with respect
to the offering and sale of new telecommunications services and could require
Lightbridge to develop modified or alternate offerings addressing the particular
needs of providers of the new telecommunications services. In addition, as the
cost of wireless communication services declines and the number of subscribers
increases, carriers may elect to forego credit verification of new customers,
and it is unclear what means of customer screening, if any, carriers will employ
if they do not use credit verification.

     Due to rapid changes in the wireless telecommunications industry,
Lightbridge intends to continue to devote substantial financial, managerial and
personnel resources to product development efforts for the foreseeable future.
The development of Lightbridge's product and service offerings is based on a
complex process requiring high levels of innovation and the accurate
anticipation of technological and market trends. There can be no assurance that
Lightbridge will be successful in developing or marketing its existing or future
product and service offerings in a timely manner, or at all. If Lightbridge is
unable, due to resource, technical or other constraints to anticipate or respond
adequately to changing market, client or technological requirements,
Lightbridge's business, financial condition, results of operations and cash flow
will be materially adversely affected. There can be no assurance that products
or services developed by others will not render Lightbridge's products or
services non-competitive or obsolete. See "Business of Lightbridge--
Competition."

     RISKS ASSOCIATED WITH MANAGING A CHANGING BUSINESS.   Lightbridge has
expanded its operations rapidly, and this expansion has created significant
demands on Lightbridge's executive, operational, development and financial
personnel and other resources.  Additional expansion by Lightbridge, including
geographic expansion in connection with the acquisition of Coral or otherwise,
may further strain Lightbridge's management, financial and other resources.
There can be no assurance that Lightbridge's systems, procedures, controls and
existing space will be adequate to support expansion of Lightbridge's
operations.  Lightbridge's future operating results will depend on the ability
of its officers and key employees to manage changing business conditions and to
continue to improve its operational and financial control and reporting systems.
If Lightbridge's management is unable to manage growth effectively, its
business, financial condition, results of operations and cash flow could be
materially and adversely affected.  See "Business of Lightbridge--Employees" and
"Management of Lightbridge."

     The success of Lightbridge's business depends in part upon Lightbridge's
ability to attract, train and retain a sufficient number of qualified personnel
to meet its needs.  Lightbridge's teleservices call center is labor intensive;
consequently, an increase in the turnover rate among Lightbridge's teleservices
employees would increase Lightbridge's recruiting and training costs, and if
Lightbridge were unable to recruit and retain a sufficient number of these
employees, it could be forced to limit its growth or possibly curtail its
operations.  There can be no assurance that Lightbridge will be successful in
attracting, training and retaining the required number of employees to support
Lightbridge's business in the future.  See "Business of Lightbridge--Products
and Services."

     DEPENDENCE ON KEY PERSONNEL. Lightbridge's success to date has depended to
a significant extent on Pamela D.A. Reeve, its President and Chief Executive
Officer, and a number of other key personnel. With the exception of Ms. Reeve,
none of Lightbridge's personnel is a party to an employment agreement with
Lightbridge. The loss of the services of Ms. Reeve or any of Lightbridge's other
key personnel could have a material adverse effect on Lightbridge's business,
financial condition, results of operations and cash flow. Lightbridge believes
that its future success will depend in large part on its ability to attract and
retain highly qualified management, engineering, research and development, sales
and operational personnel. In particular, Lightbridge will need to hire
additional software developers in order to support and increase its software
licensing activities. Competition 


                                      16

<PAGE>
 
for all of these personnel is intense and there can be no assurance that 
Lightbridge will be successful in attracting and retaining key personnel. The 
failure of Lightbridge to hire and retain qualified personnel could have a 
material adverse effect upon Lightbridge's business, financial condition, 
results of operations and cash flow. Lightbridge does not maintain key person 
life insurance policies on any of its employees other than Ms. Reeve. See 
"Business of Lightbridge--Employees" and "Management of Lightbridge."

     DEPENDENCE ON CELLULAR MARKET AND EMERGING WIRELESS MARKETS. Lightbridge 
historically has provided its products and services predominantly to cellular 
carriers. Although the cellular market has experienced

and may reduce the market price of Lightbridge Common unless and until revenue 
growth or cost savings significant growth in recent years, there can be no
assurance that such growth will continue at similar rates, or at all, or that
cellular carriers will continue to use Lightbridge's products and services.
Further growth in Lightbridge's revenues from use of Lightbridge's Customer
Acquisition System by cellular carriers is more likely to result from expansion
into additional geographic markets for its existing clients and from general
growth of the cellular market, if any, than from the addition of new cellular
carrier clients. Declines in demand for Lightbridge's products and services,
whether as a result of competition, technological change, industry change,
general economic conditions or other factors, could have a material adverse
effect on Lightbridge's business, financial condition, results of operations and
cash flow.

     Lightbridge's future operating results will depend in part on the emergence
of the PCS market and other wireless telecommunications markets and the use of
Lightbridge's products and services by PCS and other wireless carriers.  The PCS
market is in its initial stages of development.  If the growth of the PCS market
or other new wireless markets does not meet expectations or is significantly
delayed for any reason, or if carriers in these markets do not use Lightbridge's
products and services, Lightbridge's business, financial condition, results of
operations and cash flow could be materially and adversely affected.  See
"Business of Lightbridge--Products and Services."

     HIGHLY COMPETITIVE INDUSTRY.  The market for products and services provided
to wireless carriers is highly competitive and subject to rapid change.  The
market is fragmented, and a number of companies currently offer one or more
products or services competitive with those offered by Lightbridge.  In
addition, many wireless carriers are providing or can provide, internally,
products and services competitive with those Lightbridge offers.  Trends in the
wireless telecommunications industry, including greater consolidation and
technological or other developments that make it simpler or more cost-effective
for wireless carriers to provide certain services themselves, could affect
demand for Lightbridge's services and could make it more difficult for
Lightbridge to offer a cost-effective alternative to a wireless carrier's own
capabilities.  In addition, Lightbridge anticipates continued growth in the
wireless carrier services industry and, consequently, the entrance of new
competitors in the future.

     Lightbridge believes that the principal competitive factors in the wireless
carrier services industry include the ability to identify and respond to
subscriber needs, quality and breadth of service offerings, price and technical
expertise.  Lightbridge believes that its ability to compete also depends in
part on a number of competitive factors outside its control, including the
ability to hire and retain employees, the development by others of products and
services that are competitive with Lightbridge's products and services, the
price at which others offer comparable products and services and the extent of
its competitors' responsiveness to customer needs.

     Many of Lightbridge's current and potential competitors have significantly
greater financial, marketing, technical and other competitive resources than
Lightbridge.  As a result, Lightbridge's competitors may be able to adapt more
quickly to new or emerging technologies and changes in customer requirements or
may be able to devote greater resources to the promotion and sale of their
products and services.  There can be no assurance that Lightbridge will be able
to compete successfully with its existing competitors or with new competitors.
In addition, competition could increase if new companies enter the market or if
existing competitors expand their service offerings.  An increase in competition
could result in price reductions or the loss of market share by Lightbridge and
could have a material adverse effect on Lightbridge's business, financial
condition, results of operations and cash flow.

     To remain competitive in the wireless carrier services industry, 
Lightbridge will need to continue to invest in engineering, research and 
developement, and sales and marketing. There can be no assurance that 
Lightbridge will be able tyo make the technological advances necessary to remain
competitive. In addition, current and potential competitors have established or 
may in the future establish collaborative relationships amoung themselves or 
with third parties, including third parties with whom Lightbridge has a 
relationship, to increase the visibility and utility of their products and 
services. Accordingly, it is possible that new competitors or alliances may 
emerge and rapidly acquire a significant market share. If this were to occur, 
Lightbridge's business, financial condition, results of operations and cash flow
could be materially and adversely affected. See "Business of 
Lightbridge--Competition."

     RISK OF SYSTEM FAILURE.  Lightbridge's operations are dependent upon its
ability to maintain its computer and telecommunications equipment and systems in
effective working order and to protect its systems against damage from fire,
natural disaster,  power loss, telecommunications failure or similar events.
Substantially all of Lightbridge's computer and telecommunications equipment is
located at its sites in Burlington and Waltham, Massachusetts, and, as a result,
may be vulnerable to a natural disaster.  Lightbridge has taken precautions to
protect itself and its clients from events that could interrupt delivery of
Lightbridge's services.  These precautions include physical security systems,
back-up and off-site data storage, back-up telephone lines, service arrangements
with multiple long-distance telephone carriers and on-site power generators.
Notwithstanding such precautions, there can be no assurance that a fire, natural
disaster, power loss, telecommunications failure or similar event would not
result in an interruption of Lightbridge's services.  From time to time,
Lightbridge has experienced delays in the delivery of services to some clients
as a result of failures of certain of Lightbridge's systems.  Lightbridge
recently relocated its corporate headquarters from Waltham to its current,
larger facilities in Burlington, and this relocation may result in delays and
interruptions as Lightbridge seeks to build its marketing infrastructure and
relationships and to develop new products and significant new versions of its
existing products.  In addition, the growth of Lightbridge's client base, a
significant increase in transaction volume or an expansion of Lightbridge's
facilities may strain the capacity of its computers and telecommunications
systems and lead to degradations in performance or system failure.  Many of
Lightbridge's agreements with carriers contain level of service commitments
which Lightbridge might be unable to fulfill in the event of a natural disaster
or major system failure.  Any damage, failure or delay that causes interruptions
in Lightbridge's operations could have a material adverse effect on
Lightbridge's business, financial condition, results of operations and cash
flow.  Further, any future addition or expansion of Lightbridge's facilities to
increase capacity could increase Lightbridge's exposure to damage from fire,
natural disaster, power loss, telecommunications failure or similar events.
There can be no assurance that Lightbridge's property and business interruption
insurance will be adequate to compensate Lightbridge for any losses that may
occur in the event of a system failure or that such insurance will continue to
be available to Lightbridge at all or, if available, that it will be available
on commercially reasonable terms.  See "Business of Lightbridge--Products and
Services."

     In addition to its own systems, Lightbridge relies on certain equipment,
systems and services from third parties that are also subject to risks,
including risks of system failure or inadequacy.  For example, in providing its
credit verification service, Lightbridge is dependent on access to various
credit information data bases.  Similarly, delivery of Lightbridge's activation
services is often dependent on the availability and performance of third-party
billing systems.  If, for any reason, Lightbridge were unable to access any such
data bases or third-party billing systems, Lightbridge's ability to process
credit verification transactions could be impaired.  In addition, Lightbridge's
business is materially dependent on service provided by various local and long
distance telephone companies.  A significant increase in the cost of telephone
services that is not recoverable through an increase in the price of
Lightbridge's services, or any significant interruption in telephone services,
could have a material adverse effect on Lightbridge's business, financial
condition, results of operations and cash flow.

     RISK OF SOFTWARE DEFECTS; DEPENDENCE ON THIRD-PARTY SOFTWARE.  The software
developed and utilized by Lightbridge in providing its products and services may
contain errors. Although Lightbridge engages in extensive testing of its
software before it is used to provide services to clients, there can be no
assurance that errors will not be found in software after commencement of the
use of such software. Any such error may result in Lightbridge's partial or
total inability to provide services to its clients, additional and unexpected
expenses to fund further 

                                      18



                                       
<PAGE>
 


product development or to add programming personnel to complete a development
project, or loss of revenue because of the inability of clients to use
Lightbridge's products or services or the termination by clients of their
arrangements with Lightbridge. Any of these results could have a material
adverse effect on Lightbridge's business, financial condition, results of
operations and cash flow. In particular, certain of the software developed or
used by Lightbridge currently may be unable to interpret properly dates for the
year 2000 and beyond. Any failure by Lightbridge to identify such a "year 2000"
problem in such software could cause errors that materially impair the utility
of one or more of Lightbridge's products and services. Even if such a problem is
defined, resolution of the problem may require significant expenditures and may
not be achievable by January 1, 2000. As a result, any such problem may have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow.

     Certain software used in Lightbridge's software products and to support
Lightbridge's qualification and activation services is licensed by Lightbridge
from third parties.  Lightbridge licenses software from Pilot Software, Inc.
under a license agreement that will expire in December 2000 and licenses
software from Trans Union Corporation under a three-year agreement.  There can
be no assurance that these suppliers will continue to license this software to
Lightbridge or, if any supplier terminates its agreement with Lightbridge, that
Lightbridge will be able to develop or otherwise procure software from another
supplier on a timely basis or on commercially reasonable terms.  Even if
Lightbridge succeeds in developing or procuring such software in such
circumstances, there can be no assurance that Lightbridge will be able to do so
in a timely fashion.  See "Business of Lightbridge--Proprietary Rights."

     RISKS ASSOCIATED WITH POTENTIAL ACQUISITIONS. Lightbridge may in the future
pursue additional acquisitions of companies, technologies or assets that
complement Lightbridge's business. Future acquisitions may result in the
potentially dilutive issuance of equity securities, the incurrence of additional
debt, the write-off of in-process research and development or software
acquisition and development costs, and the amortization of expenses related to
goodwill and other intangible assets, any of which could have a material adverse
effect on Lightbridge's business, financial condition, results of operations and
cash flow. Future acquisitions would involve numerous additional risks,
including difficulties in the assimilation of the operations, services, products
and personnel of the acquired company, the diversion of management's attention
from other business concerns, entering markets in which Lightbridge has little
or no direct prior experience, and the potential loss of key employees of the
acquired company.

     GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES.  The wireless carriers that
constitute Lightbridge's clients are regulated at both the federal and state
levels.  Federal and state regulation may decrease the growth of the wireless
telecommunications industry, affect the development of the PCS or other wireless
markets, limit the number of potential clients for Lightbridge's services,
impede Lightbridge's ability to offer competitive services to the wireless
telecommunications market, or otherwise have a material adverse effect on
Lightbridge's business, financial condition, results of operations and cash
flow.  The Telecommunications Act of 1996, which in large measure deregulated
the telecommunications industry, has caused, and is likely to continue to cause,
significant changes in the industry, including the entrance of new competitors,
consolidation of industry participants and the introduction of bundled wireless
and wireline services.  Those changes could in turn subject Lightbridge to
increased pricing pressures, decrease the demand for Lightbridge's products and
services, increase Lightbridge's cost of doing business or otherwise have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow.

     As the result of offering its ProFile product, Lightbridge is subject to
the requirements of the Fair Credit Reporting Act and certain state laws.
Although Lightbridge's business activities are not otherwise within the scope of
federal or state regulations applicable to credit bureaus and financial
institutions, Lightbridge must take into account such regulations in order to
provide products and services that help its clients comply with such
regulations. Lightbridge monitors regulatory changes and implements changes to
its products and services as appropriate. Although Lightbridge attempts to
protect itself by written agreements with its clients, failure to reflect the
provisions of such regulations in a timely or accurate manner could possibly
subject Lightbridge to liabilities 

                                       19
<PAGE>
 
that could have a material adverse effect on Lightbridge's business, financial
condition, results of operations and cash flow. See "Business of Lightbridge--
Government Regulation."

     LIMITED PROTECTION OF PROPRIETARY TECHNOLOGY; RISK OF THIRD PARTY CLAIMS.
Lightbridge's success is dependent upon proprietary technology.  Lightbridge
currently has no patents and protects its property rights in its technology
primarily through copyrights, the law of trademarks, trade secrets and employee
and third-party non-disclosure agreements.  There can be no assurance that the
steps taken by Lightbridge to protect its proprietary rights will be adequate to
prevent misappropriation of its technology or independent development by others
of similar technology.  In addition, the laws of some foreign countries do not
protect Lightbridge's proprietary rights to the same extent as do the laws of
the United States.  There can be no assurance that these protections will be
adequate.

     Although Lightbridge believes that its products and technology do not
infringe on any existing proprietary rights of others, there can be no assurance
that third parties will not assert claims of infringement against Lightbridge in
the future or that any such future claims will not be successful. Lightbridge
could incur substantial costs and diversion of management resources with respect
to the defense of any claims relating to proprietary rights, which could have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow. Furthermore, parties making such claims could
secure a judgment awarding substantial damages, as well as injunctive or other
equitable relief, which could effectively block Lightbridge's ability to make,
use, sell, distribute or market its products and services in the United States
or abroad. Such a judgment could have a material adverse effect on Lightbridge's
business, financial condition, results of operations and cash flow. In the event
a claim relating to proprietary technology or information is asserted against
Lightbridge, Lightbridge may seek licenses to such intellectual property. There
can be no assurance, however, that such a license could be obtained on
commercially reasonable terms, if at all, or that the terms of any offered
licenses will be acceptable to Lightbridge. The failure to obtain the necessary
licenses or other rights could preclude the sale, manufacture or distribution of
Lightbridge's products and, therefore, could have a material adverse effect on
Lightbridge's business, financial condition, results of operations and cash
flow. The cost of responding to any such claim may be material, whether or not
the assertion of such claim is valid. See "Business of Lightbridge--Proprietary
Rights."

     RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION.  As part of its business
strategy, Lightbridge may seek opportunities to expand its offerings into
international markets.  Lightbridge does not currently derive any significant
revenues from international markets, although a material portion of Coral's
revenues are derived from international sales.  See "Business of Coral--Sales,
Marketing and Distribution."  Lightbridge believes that expansion of its
offerings into international markets is important to Lightbridge's ability to
continue to grow and to market its products and services.  In particular, some
domestic wireless carriers expanding into international markets may seek single,
global solutions from Lightbridge and its competitors, and as a result, the
inability of Lightbridge to offer its products and services internationally may
have an adverse effect on Lightbridge's ability to market its products and
services to those carriers for use in the United States.  In marketing its
products and services internationally, however, Lightbridge will face new
competitors, some of whom may have established strong relationships with
carriers.  There can be no assurance that Lightbridge will be successful in
marketing or distributing its services abroad or that, if Lightbridge is
successful, its international revenues will be adequate to offset the expense of
establishing and maintaining international operations.  To date, Lightbridge has
limited experience in marketing and distributing its services internationally.
In addition to the uncertainty as to Lightbridge's ability to establish an
international presence, there are certain difficulties and risks inherent in
doing business on an international level, such as compliance with regulatory
requirements and changes in these requirements, export restrictions, export
controls relating to technology, tariffs and other trade barriers, difficulties
in staffing and managing international operations, longer payment cycles,
problems in collecting accounts receivable, political instability, fluctuations
in currency exchange rates, seasonal reductions in business activity during the
summer months in Europe and certain other parts of the world and potentially
adverse tax consequences.  There can be no assurance that one or more of such
factors will not have a material adverse effect on any international operations
established by Lightbridge and, consequently, on Lightbridge's business,
financial condition, results of operations and cash flow.

                                       20
<PAGE>
 
     POSSIBLE VOLATILITY OF STOCK PRICE.  Factors such as announcements of
technological innovations or new products by Lightbridge, its competitors and
other third parties, as well as quarterly variations in Lightbridge's results of
operations and market conditions in the industry, may cause the market price of
Lightbridge Common to fluctuate significantly. In addition, the stock market in
general has experienced substantial price and volume fluctuations, which have
particularly affected the market prices of many technology companies and which
have often been unrelated to the operating performance of such companies. These
broad market fluctuations may adversely affect the market price of Lightbridge
Common.

     ANTI-TAKEOVER EFFECT OF PROVISIONS OF CHARTER, BY-LAWS AND DELAWARE LAW.
Lightbridge's Amended and Restated Certificate of Incorporation (the
"Lightbridge Charter") and its Amended and Restated By-Laws (the "Lightbridge 
By-Laws") contain provisions that could discourage a proxy contest or make more
difficult the acquisition of a substantial block of Lightbridge Common. The
Lightbridge Charter requires that any action required or permitted to be taken
by stockholders of Lightbridge must be effected at a duly called annual or
special meeting of stockholders and may not be effected by any consent in
writing. The Lightbridge By-Laws require specified advance notice by a
stockholder of a proposal or director nomination which such stockholder desires
to present at any annual or special meeting of stockholders. Special meetings of
stockholders may be called only by the President or a majority of the Board of
Directors. The Lightbridge By-Laws provide for a classified Board of Directors,
and members of the Board of Directors may be removed only for cause upon the
affirmative vote of holders of at least two-thirds of the shares of capital
stock of Lightbridge issued and outstanding and entitled to vote. The
affirmative vote of the holders of at least 75% of the shares of capital stock
of Lightbridge issued and outstanding and entitled to vote is required to amend
or repeal these provisions. In addition, the Board of Directors is authorized to
issue shares of Lightbridge Common and preferred stock that, if issued, could
dilute and adversely affect various rights of the holders of Lightbridge Common
and, in addition, could be used to discourage an unsolicited attempt to acquire
control of Lightbridge.

     Lightbridge is subject to the anti-takeover provisions of Section 203 of
the Delaware Law, which prohibit Lightbridge from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
The application of Section 203 may limit the ability of stockholders to approve
a transaction that they deem to be in their best interests. The foregoing and
other provisions of the Lightbridge Charter, the Lightbridge By-Laws and
Delaware Law could have the effect of deterring certain takeovers or delaying or
preventing certain changes in control or management of Lightbridge, including
transactions in which stockholders might otherwise receive a premium for their
shares over then current market prices.

                              THE SPECIAL MEETING

     At the Special Meeting, holders of Coral Common, as a class, and holders of
Coral Series A, Coral Series B and Coral Series C, voting as a single class on
an as-converted basis, will consider and vote upon the Merger Proposal, which
proposes to approve both (i) the Reorganization Agreement, which was entered
into among Lightbridge, Acquisition Corp. and Coral as of September 9, 1997, and
(ii) the Merger, in which Acquisition Corp. would merge with and into Coral and
the Surviving Corporation would become a wholly owned subsidiary of Lightbridge,
all in accordance with the provisions of the Reorganization Agreement.

     THE BOARD OF DIRECTORS OF CORAL HAS UNANIMOUSLY APPROVED THE REORGANIZATION
AGREEMENT AND THE MERGER, AND UNANIMOUSLY RECOMMENDS THAT CORAL STOCKHOLDERS
VOTE FOR THE MERGER PROPOSAL.  See "The Merger Proposal--Background of the
Merger" and "--Coral's Reasons for the Merger; Recommendation of the Board of
Directors of Coral."

RECORD DATE; QUORUM
    
     The Coral Board of Directors has fixed the close of business on October 8,
1997 as the Record Date for determining holders of Coral Capital Stock entitled
to notice of and to vote at the Special Meeting, including any adjournment or
postponement thereof. The presence, in person or by duly authorized proxy, of
the holders of one-third of the outstanding shares of Coral Common and of the
holders of one-third of the outstanding shares of the Coral Series A, Coral
Series B and Coral Series C (on an as-converted basis) is necessary to
constitute a quorum at the Special Meeting. Abstentions will be included as
present or represented for purposes of establishing a quorum for the transaction
of business.     

REQUIRED VOTES

     Holders of Coral Common are entitled to cast one vote per share of Coral
Common. Holders of Coral Series A, Coral Series B and Coral Series C are
entitled to cast the number of shares of Coral Common into which such shares of
Coral Series A, Coral Series B or Coral Series C, as the case may be, are
convertible as of the date of the Special Meeting.

     Approval of the Merger Proposal requires both (i) the affirmative vote of
the holders of a majority of the outstanding shares of Coral Common entitled to 
vote at the Special Meeting and (ii) the affirmative vote of the holders of a
majority of the outstanding shares of Coral Series A, Coral Series B and Coral
Series C, voting as a single class on an as-converted basis, entitled to vote at
the Special Meeting. Accordingly, abstentions will have the same practical
effect as a vote against the Merger Proposal.
    
     CERTAIN CURRENT AND FORMER DIRECTORS AND OTHER AFFILIATES OF CORAL, WHO OWN
AS A GROUP APPROXIMATELY 69.9% OF THE OUTSTANDING SHARES OF CORAL COMMON AND
50.1% OF THE CORAL SERIES A, CORAL SERIES B AND CORAL SERIES C (ON AN AS-
CONVERTED BASIS), HAVE EXECUTED VOTING AGREEMENTS WITH LIGHTBRIDGE PURSUANT TO
WHICH THEY HAVE AGREED TO VOTE IN FAVOR OF THE MERGER PROPOSAL AND HAVE
DELIVERED TO LIGHTBRIDGE IRREVOCABLE LIMITED PROXIES WITH RESPECT TO THE MERGER
PROPOSAL.  ACCORDINGLY, THOSE VOTING AGREEMENTS AND IRREVOCABLE LIMITED PROXIES
ARE SUFFICIENT TO EFFECT THE APPROVAL OF THE MERGER PROPOSAL.  See "Other
Agreements--Voting Agreements."     

VOTING RIGHTS; PROXIES
    
     As of the Record Date, there are expected to be issued and outstanding
3,276,134 shares of Coral Common, entitling each holder thereof to one vote. In
addition, there are expected to be issued and outstanding 2,000,000 shares of
Coral Series A, 2,083,333 shares of Coral Series B and 1,824,920 shares of Coral
Series C, each of which would entitle the holder thereof (on an as-converted
basis) to one-half vote, one vote and one-half vote, respectively. All shares of
Coral Capital Stock represented by properly executed proxies will be voted,
unless such proxies have been previously revoked, in accordance with the
instructions indicated in such proxies. IF NO 

                                       23
<PAGE>
 
INSTRUCTIONS ARE INDICATED, SUCH SHARES OF CORAL CAPITAL STOCK WILL BE VOTED IN
FAVOR OF APPROVAL OF THE MERGER PROPOSAL. Coral does not know of any matters
other than the Merger Proposal that are to come before the Special Meeting. If
any other matter or matters are properly presented for action at the Special
Meeting, the persons named in the enclosed form of proxy and acting thereunder
will have the discretion to vote on such matters in accordance with their best
judgment, unless such authorization is withheld. A holder of shares of Coral
Capital Stock giving a proxy pursuant to this proxy solicitation may revoke the
proxy at any time before it is exercised by delivering to the Secretary of Coral
a written notice of revocation prior to the voting of the proxy at the Special
Meeting, by signing and returning a later dated proxy or by attending the
Special Meeting and informing the Secretary of Coral in writing that such
stockholder wishes to vote those shares in person. Mere attendance at the
Special Meeting will not in and of itself have the effect of revoking the proxy.

SOLICITATION OF PROXIES

     Coral will bear the cost of soliciting proxies. In addition to the
solicitation by mail, the directors, officers and certain employees of Coral may
solicit proxies, without additional remuneration, by telephone, facsimile,
telegraph and in person. It is expected that the expense of such special
solicitation will be nominal.

DISSENTERS' RIGHTS

     Any holder of shares of Coral Common, Coral Series A, Coral Series B or
Coral Series C may dissent from the Merger and demand appraisal of those shares
by following the procedures set forth in Section 262 of the Delaware Law. See
"The Merger Proposal--Appraisal Rights" and Annex B hereto. 

                                       24
<PAGE>
 
                              THE MERGER PROPOSAL

     This section of this Proxy Statement/Prospectus, as well as the next two
sections of this Proxy Statement/Prospectus entitled "The Reorganization
Agreement" and "Other Agreements," describe certain aspects of the proposed
Merger. To the extent that they relate to the Reorganization Agreement, or the
other agreements described under "Other Agreements," the following
descriptions do not purport to be complete and are qualified in their entirety
by reference to the Reorganization Agreement, which is attached as Annex A to
this Proxy Statement/Prospectus and is incorporated herein by reference, and
such other agreements, which are filed as exhibits to the Registration Statement
and are incorporated herein by reference. All Coral stockholders are urged to
read the Reorganization Agreement and such other agreements in their entireties.

GENERAL

     The Reorganization Agreement provides that the Merger will be consummated
if the required approvals of the Coral stockholders are obtained and all other
conditions to the Merger are satisfied or waived. Upon consummation of the
Merger, Acquisition Corp. will be merged with and into Coral, and the Surviving
Corporation will become a wholly owned subsidiary of Lightbridge.

     Pursuant to the Merger, each of the outstanding shares of Coral Common,
Coral Series A, Coral Series B and Coral Series C, other than duly qualified
dissenting shares, would convert into a fraction of a share of Lightbridge
Common determined as set forth in the Reorganization Agreement, as described
under "--Calculation of Merger Consideration." Pursuant to Section 1.4.2 of the
Reorganization Agreement, all outstanding Options and Warrants to purchase Coral
Common will become exercisable to purchase shares of Lightbridge Common.

     Upon consummation of the Merger, holders of Coral stock will cease to have
any direct equity interest in Coral.  The Lightbridge Common to be received by
holders of Coral Shares upon consummation of the Merger will provide those
holders with an opportunity to have a continuing equity interest in the combined
operations of Lightbridge and Coral.

EFFECTIVE DATE AND TIME OF THE MERGER

     Consummation of the Merger will occur at the Effective Time, upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware in the form required by, and executed in accordance with, Delaware Law
(the "Certificate of Merger"). The term "Effective Time" means the particular
time at which the parties to the Reorganization Agreement cause the Merger to be
consummated by filing with the Secretary of State of the State of Delaware. The
filing of the Certificate of Merger will occur as soon as practicable after the
satisfaction or waiver of all conditions to the closing of the transactions
contemplated by the Reorganization Agreement, which is anticipated to be on or
about the business day following the date of the Special Meeting. The
Reorganization Agreement may be terminated, under certain circumstances, by
either party if the Merger shall not have been consummated on or before December
31, 1997. The Reorganization Agreement also may be terminated under certain
other circumstances. See "The Reorganization Agreement--Conditions to the
Merger" and "--Termination."

CALCULATION OF MERGER CONSIDERATION

     Pursuant to the terms of the Reorganization Agreement, shares of
Lightbridge Common will be (i) issued upon conversion of all of the outstanding
shares of Coral Capital Stock (other than duly qualified dissenting shares) and
(ii) reserved for issuance upon the exercise of all unexpired and unexercised
Options and Warrants. Under the Reorganization Agreement, the rate at which any
share of Coral Capital Stock will be converted into Lightbridge Common will be
computed in three steps.

                                       25
<PAGE>
 
     .    First, the maximum number of shares of Lightbridge Common to be issued
          upon conversion of outstanding shares of Coral Capital Stock or
          reserved for issuance upon the exercise of Options and Warrants (the
          "Initial Share Number") will be computed, based upon the Calculation
          Price. The Calculation Price will be the average of the last reported
          sale prices per share of Lightbridge Common on the Nasdaq National
          Market over the ten trading days prior to the date on which 
          Lightbridge publicly announces its operating results for the quarter
          ended September 30,1997. The Initial Share Number will be determined
          as follows:

          (a)  if the Calculation Price is between $10.8375 and $14.6625, the
               Initial Share Number will be 1,286,863;

          (b)  if the Calculation Price is less than $10.8375, the Initial Share
               Number will be the quotient of $13,946,375 divided by the
               Calculation Price, rounded down to the nearest whole number of
               shares of Lightbridge Common; and

          (c)  if the Calculation Price is greater than $14.6625, the Initial
               Share Number will be the quotient of $18,868,625 divided by the
               Calculation Price, rounded down to the nearest whole number of
               shares of Lightbridge Common.

     .    Second, the Initial Share Number will be decreased by a number of
          shares equal to the Adjustment Amount divided by the Calculation
          Price. The Adjustment Amount will equal the dollar amount of certain
          expenses attributable to the Coral stockholders in connection with the
          Merger, as provided for in Section 5.11 of the Reorganization
          Agreement, plus (or minus) the amount by which Coral's working capital
          (total current assets less total current liabilities) as of the date
          of the Closing, as determined pursuant to a post-closing audit, is
          less (or greater) than negative $1,245,500. The stockholder expenses
          to be included in the Adjustment Amount will include, among other
          things, fees and disbursements of Coral's legal counsel and
          independent accountants, disbursements of Coral's financial advisor,
          expenses of Coral in connection with the proxy solicitation being made
          by this Proxy Statement/Prospectus, and other costs and expenses of
          Coral arising in connection with the Merger prior to the Closing. The
          Adjustment Amount will not include a total of $500,000 of fees of
          Coral's financial advisor or $220,000 of bonus payments due to certain
          officers of Coral as a result of the consummation of the Merger (see 
          "-- Interests of Certain Persons in the Merger"). No adjustment will
          be made in the number of shares of Lightbridge Common issued in the
          Merger as a result of any cash proceeds received by Coral from the
          date of the Reorganization Agreement to the Effective Time pursuant to
          the exercise of Options or Warrants to acquire Coral Capital Stock.

     .    Third, the Initial Share Number, less the number of shares equal to
          the Adjustment Amount divided by the Calculation Price of Lightbridge
          Common, will be allocated among the shares of the different classes of
          Coral Capital Stock. As described below, the conversion rates for each
          class of Coral Capital Stock generally will (i) treat as outstanding
          the shares of Coral Common issuable upon exercise of Options and
          Warrants (whether or not vested) and (ii) allocate the shares of
          Lightbridge Common issuable upon the Merger to each class of Coral
          Capital Stock based upon the liquidation preferences set forth in the
          Coral Charter. Specifically:

          (a)  Each outstanding share of Coral Capital Stock (other than any
               duly qualified dissenting shares) will be converted into the
               right to receive:

               (i)  the number of shares of Lightbridge Common that, when
                    divided by the Calculation Price, equals the
                    liquidation preference of such class of Coral Capital
                    Stock, plus

               (ii) such share's pro rata portion, on an as-converted
                    basis, of the Initial Share Number, less the number of
                    shares reflecting the Adjustment Amount, that remains
                    unallocated 

                                       26
<PAGE>
 
                    after shares of Lightbridge Common have been allocated to
                    each share of Coral Capital Stock in accordance with the
                    foregoing clause (i) and shares of Lightbridge Common have
                    been reserved for the exercise of all unexpired and
                    unexercised Options and Warrants outstanding at the
                    Effective Time (as described in clause (b) below).
 
          (b)  Each Option and Warrant outstanding at the Effective Time,
               whether vested or unvested, will entitle its holder, upon
               exercise (if and when vested) following the Effective Time,
               to receive that number of whole shares of Lightbridge Common
               equal to the product of the number of shares of Coral Common
               that were issuable upon exercise of such Option or Warrant
               immediately prior to the Effective Time (without regard to
               vesting) multiplied by the conversion rate for a single
               share of Coral Common, rounded down to the nearest whole
               number of shares of Lightbridge Common. In addition,
               following the Effective Time, the per share exercise price
               for the Lightbridge Common issuable upon exercise of each
               Option and Warrant would be equal to the per share exercise
               price thereof immediately prior to the Effective Time
               divided by the conversion rate for a single share of Coral
               Common.
    
     Because the Calculation Price is not currently known and the Adjustment
Amount cannot currently be determined, the precise conversion rate for each
class of Coral Capital Stock cannot currently be calculated. The following 
examples are provided for purposes of illustration only.  For purposes of these 
examples, (a) the stockholder expenses to be included in the Adjustment Amount 
are assumed to total $400,000, based on a preliminary estimate made by the 
management of Coral and Lightbridge as of the date hereof, and (b) the working
capital adjustment to be included in the Adjustment Amount is assumed to be
either $0 (that is, Coral's working capital as of the date of the Closing is
assumed to equal negative $1,245,500) or $1,462,100, based on Coral's estimate
of its working capital of negative $2,707,600 as of August 31, 1997. THE ACTUAL
NUMBER OF SHARES OF LIGHTBRIDGE COMMON ISSUED (AND RESERVED FOR ISSUANCE) IN THE
MERGER AND THE RELATED CONVERSION RATES MAY DIFFER MATERIALLY FROM THESE
EXAMPLES.    
    
     .    Assuming a Calculation Price of $12.75 (the last reported price per
          share of Lightbridge Common on the date as of which a nonbinding oral
          agreement was initially reached between Coral and Lightbridge), (i) if
          the Adjustment Amount totalled $400,000, an aggregate of 1,255,490
          shares of Lightbridge Common would be issuable to Coral stockholders
          (and reserved for issuance upon exercises of Options and Warrants) and
          (ii) if the Adjustment Amount totalled $1,862,100, an aggregate of
          1,140,816 shares of Lightbridge Common would be issuable to Coral
          stockholders (and reserved for issuance upon exercises of Options and
          Warrants). Based upon those assumptions, each share of Coral Capital
          Stock would be converted into a fraction of a share of Lightbridge
          Common as follows:

          the Adjustment Amount totalled $400,000, an aggregate of 1,163,378
          shares of Lightbridge Common would be issuable to Coral stockholders

          reservation) of such 1,107,564 and 1,019,862 shares of Lightbridge

          OF THE MERGER PROPOSAL WILL CONFER UPON THE BOARD OF DIRECTORS OF

          CORAL THE POWER, CONSISTENT WITH ITS FIDUCIARY DUTIES, TO CONSUMMATE
          THE MERGER IN THE EVENT THAT THE CALCULATION PRICE OF THE LIGHTBRIDGE
          COMMON IS LESS THAN $9.5625 OR MORE THAN $15.9375. See "The
          Reorganization Agreement--Termination."     

     The shares of Lightbridge Common issued in connection with the Merger will
be subject to indemnification and escrow provisions of the Reorganization
Agreement and the Escrow Agreement. See "Description of Reorganization 
Agreement-- Indemnification" and "Other Agreements--Escrow Agreement."
    
     In addition to the rights provided to holders of Coral stock under the
Reorganization Agreement, prior to the filing of the Charter Amendment (as
described below), the Merger would have triggered certain additional rights of
the holders of Coral Series A, Coral Series B and Coral Series C. Pursuant to
the terms of Article IV, Section C.4.k. of the Coral Charter, any such holder
could have elected, on an individual basis, either (i) to treat the Merger as a
liquidation pursuant to Article IV, Section C.2.c. of the Coral Charter or (ii)
to have such holder's preferred stock remain outstanding and become exercisable
for Lightbridge Common. Lightbridge determined that it would be untenable for it
to, in effect, assume all or any portion of the Coral Series A, Coral Series B
or Coral Series C.     
    
     To address the foregoing issues, concurrently with the execution of the
Reorganization Agreement, the holders of a majority of the outstanding shares of
each class of Coral Capital Stock delivered to Coral a written action by consent
of stockholders, pursuant to which such holders duly approved and adopted a
certificate of amendment to the Coral Charter that was filed with the Secretary
of State of the State of Delaware and became effective on September 17, 1997
(the "Charter Amendment"). The Charter Amendment provides that the Merger will
not be subject to the foregoing provisions of the Coral Charter. Although the
holders of Coral preferred stock will not have the right to elect to treat the
Merger as a deemed liquidation, the portion of the Merger Consideration to be
allocated to a share of a particular class of Coral Capital Stock was made
dependent on the liquidation preference for that class under the Coral Charter,
as described above.     

     No fractional shares of Lightbridge Common shall be issuable in connection
with the Merger.  The number of shares of Lightbridge Common to be issued upon
conversion of all outstanding shares of Coral Capital Stock and to be reserved
for exercise of all Options and Warrants shall equal the Initial Share Number
less the number of shares reflecting the Adjustment Amount, and, to the extent
the calculations pursuant to Section 1.4.2 of the Reorganization Agreement
produce fractional shares or an aggregate number greater or less than such
number, the number of shares of Lightbridge Common allocable to individual
holders of Coral Capital Stock, Options and Warrants shall be appropriately
adjusted.

CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES

     The conversion of Coral Shares into Lightbridge Common and the conversion 
of Options and Warrants into the right to purchase Lightbridge Common will occur
automatically at the Effective Time.

     As soon as reasonably practicable after the Effective Time, Lightbridge 
will instruct the Exchange Agent to mail to each holder of record of shares of 
Coral Capital Stock a letter of transmittal and instructions to effect the 
surrender of the certificates representing shares of Coral Capital Stock, in 
exchange for certificates representing the shares of Lightbridge Common issuable
therefor in connection with the Merger. Approximately one-third of such shares 
of Lightbridge Common will be issued and delivered to the Exchange Agent 
promptly after the Effective Time, for delivery to the former Coral holders six 
months after the date of the Closing. The balance of such shares will be issued 
and delivered to the escrow agent under the Escrow Agreement and will become 
deliverable to former holders of Coral Capital Stock in accordance with the 
terms of the Escrow Agreement. See "Other Agreements--Escrow Agreement."

     Upon surrender of a certificate representing Coral shares for cancellation 
to the Exchange Agent, together with a duly executed letter of transmittal and 
any other documents as may be required pursuant to such instructions, the holder
of such certificate will be entitled to receive in exchange therefor (i) a 
certificate

                                      29
     



<PAGE>
 
evidencing that number of whole shares of Lightbridge Common which such holder
has the right to receive in the Merger, subject to the limitations on delivery 
described in the preceding paragraph, (ii) any dividends or other distributions 
on the shares of Lightbridge Common which such holder is entitled to receive and
(iii) cash in respect of fractional shares of Lightbridge Common (the shares of 
Lightbridge Common, distributions and cash described in clauses (i), (ii) and 
(iii) being, collectively, the "Merger Consideration"), and the certificate 
representing Coral shares so surrendered shall forthwith be canceled. In the 
event of a transfer of ownership of Coral shares that is not registered in the 
transfer records of Coral as of the Effective Time, the Merger Consideration may
be issued and paid to a transferee if the certificate evidencing such Coral 
shares is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until so surrendered, each outstanding
certificate that, prior to the Effective Time, represented Coral shares will be
deemed from and after the Effective Time, for all corporate purposes (other than
payment of dividends or a described below under "-- Appraisal Rights'), to
evidence the ownership of the number of full shares of Lightbridge Common into
which such Coral shares shall have been so converted, subject to the delivery
and escrow provisions of the Reorganization Agreement and Escrow Agreement.

     DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED OR ESCROWED CORAL SHARES. No 
dividends or other distributions declared or made after the Effective Time with 
respect to Lightbridge Common with a record date after the Effective Time will 
be paid to the holder of an unsurrendered certificate representing Coral shares 
with respect to the shares of Lightbridge Common such holder is entitled to 
receive until the holder surrenders such certificate. Further, any such 
dividends or other distributions with respect to shares of Lightbridge Common 
held in escrow under the Escrow Agreement shall be delivered to the Escrow Agent
and shall be subject to the escrow provisions of the Escrow Agreement. Subject 
to applicable law, following surrender of any certificate representing Coral 
shares, there shall be paid to the record holder of the certificates 
representing whole shares of Lightbridge Common issued in exchange therefor, 
without interest, at the time of surrender, the amount of dividends or other 
distributions with a record date after the Effective Time theretofore paid with 
respect to such whole shares of Lightbridge Common.

     TRANSFERS OF OWNERSHIP. If any certificate for Lightbridge Common is to be 
issued in a name other than that in which the certificate representing Coral 
shares surrendered in exchange therefor is registered, it will be a condition of
the issuance thereof that the certificate so surrendered will be properly 
endorsed and otherwise in proper form for transfer and that the person 
requesting such exchange will have paid to Lightbridge or any designated agent 
any transfer or other taxes required by reason of the issuance of a certificate 
for shares of Lightbridge Common in any other name other than that of the 
registered holder of the certificate surrendered, or established to the 
satisfaction of Lightbridge (or any designated agent) that such tax has been 
paid or is not payable.

     WITHHOLDING RIGHTS. Lightbridge or the Exchange Agent will be entitled to 
deduct and withhold from the Merger Consideration otherwise payable to any Coral
stockholder pursuant to the Reorganization Agreement such amounts as Lightbridge
or the Exchange Agent is required to deduct and withhold with respect to the 
making of such payment under any provision of federal, state or local tax law. 
To the extent that amounts are so withheld by Lightbridge or the Exchange Agent,
such withheld amounts shall be treated for purposes of the Reorganization 
Agreement as having been paid to the holder of the shares of Lightbridge Common 
in respect of which such deduction and withholding was made by Lightbridge or 
the Exchange Agent.

     LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any certificates
representing shares or Coral Capital Stock have been lost, stolen or destroyed,
the Exchange Agent will issued shares of Lightbridge Common in exchange for such
lost, stolen or destroyed certificates upon the making of any affidavit of that
fact by the owner of such certificates and, at the request of Lightbridge, upon
delivery of a bond in such a sum as Lightbridge may reasonably direct as
indemnity against any claim that may be made against Lightbridge or the Exchange
Agent with respect to the certificates alleged to have been lost, stolen or
destroyed.

DETAILED INSTRUCTIONS, INCLUDING A TRANSMITTAL LETTER, WILL BE MAILED TO CORAL 
STOCKHOLDERS PROMPTLY FOLLOWING THE EFFECTIVE TIME AS TO THE METHOD FOR 
EXCHANGING THEIR CERTIFICATES. HOLDERS OF SHARES OF CORAL STOCK SHOULD NOT 
RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY, AND THEY SHOULD NOT FORWARD 
STOCK CERTIFICATES TO THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL 
LETTERS.

                           BACKGROUND OF THE MERGER

     Coral was initially founded in 1991. From early 1994 through early 1996, 
Coral raised approximately $11 million in capital from venture capital and other
outside investors. Coral experienced substantial growth in this period, with 
annual revenue reaching $8.7 million for 1996. Despite this revenue growth, 
however, Coral has been unable to reach sustained profitability, sustaining 
losses in 1992 through 1996 as well as for the six months ended June 30, 1997.
    
     During the second half of 1996, Coral commenced an initial public offering
of its common stock. Due to market conditions as well as Coral's inability to
report profitable results of operations for the quarter ended December 31,
1996, the offering could not be completed and was withdrawn early in 1997.     

     During early 1997, Coral's board of directors considered recommencing the 
withdrawn initial public offering. Based upon conversations with the proposed 
lead underwriter, the board determined that it was unlikely that the offering 
would be completed in the foreseeable future. In particular, it was unlikely
that the initial public offering process would be recommenced until Coral
reported several quarters of profitable results. Coral reported net losses in
the quarters ended December 31, 1996, March 31, 1997 and June 30, 1997.
    
     In February 1997, the Coral board met to consider Coral's strategic
alternatives, including pursuing potential business combinations with other
telecommunications software companies. Among other things, the Coral board
considered that substantial additional financing would have to be obtained if a
business combination were not pursued. At the meeting, the Board decided to
proceed to explore the possibility of a business combination involving 
Coral.    
         
     Thereafter, on April 18, 1997, certain members of the Coral management, 
including Mr. Eric Johnson, President and Chief Executive Officer, Mr. Kyle
Hubbart, Chief Financial Officer, and Mr. Howard Kaushansky, Vice President and
General Counsel, visited Lightbridge and met with Ms. Pamela Reeve, President
and Chief Executive Officer of Lightbridge, and Mr. William Brown, Chief
Financial Officer of Lightbridge, to discuss possible financing 
opportunities.     

     Between April 18 and April 25, 1997, there were a number of telephone
conferences between Messrs. Johnson, Hubbart and Kaushansky and Ms. Reeve and
Mr. Brown regarding merger possibilities between the two companies. During this
time, the two companies exchanged confidentiality agreements. In addition,
financial and business information (including financial projections) was
provided by Coral to Lightbridge and to their boards of directors.

     On May 15, 1997, Ms. Reeve, Mr. Brown and Mr. Richard Antell, Vice
President of Software Development of Lightbridge, met with Messrs. Johnson,
Hubbart and Kaushansky and Mr. Timothy Hayes, Chief Technical Officer of Coral,
at Coral's offices in Longmont, Colorado. Also present were representatives of
Cowen & Company, investment advisor to Lightbridge.

     On May 20, 1997, Coral retained Broadview to act as Coral's financial
advisor in connection with exploring potential business combinations. Following
its engagement, Broadview contacted a number of companies (including
Lightbridge) that had already expressed interest in a potential business
combination with Coral, as well as a number of companies that were likely to be
interested in such a combination. Several of these companies met with Coral
management to discuss possible transactions.

     During the period from May 15 to June 12, 1997, there were several
telephone conferences between the management of Lightbridge and Coral,
particularly regarding existing and potential contracts. On June 13, Lightbridge
made an offer to acquire all outstanding Coral Capital Stock, Options and
Warrants for shares of Lightbridge Common having a market value at that time of
$16.4 million. This original offer expired in accordance with its terms and was
not extended by Lightbridge.     

     By the end of June 1997, Coral's available cash resources had been 
substantially depleted. Coral began to arrange for a short-term bridge loan that
was to be followed by another round of venture capital financing. It was
anticipated that the shares to be issued in such financing round would be
substantially below the price at which shares had been issued in previous 
rounds, and that the proposed financing would result in substantial dilution to
Coral's existing stockholders. The proposed financing was not consummated
because Coral was able to obtain additional accounts receivable financing from
its bank lender.

     On July 21, 1997, the Lightbridge board of directors held a meeting via
teleconference to discuss the Merger. On July 23, Lightbridge made an offer to
the Coral board of directors to purchase all outstanding Coral Capital Stock,
Options and Warrants for shares of Lightbridge Common having a market value of
$19.1 million. On July 25, Mr. John Fraser, the President of Coral, and a
representative of Broadview, investment advisor to Coral, met with Ms. Reeve,
Mr. Brown and a representative of Cowen & Company to discuss the Merger. On July
25, a letter of intent was signed by both companies, outlining the general terms
of the Reorganization Agreement.

     Between August 4 and August 6, 1997, Mr. Kevin Collins, Controller of 
Lightbridge, and Mr. Joseph Pignato, Assistant Controller of Lightbridge, with 
representatives of Cowen & Company and Foley, Hoag & Eliot LLP, visited the 
offices of Coral in Longmont, Colorado, for the purposes of financial, 
accounting and legal due diligence.

     Between August 5 and August 7, 1997, a number of members of Coral's
management, including Messrs. Fraser and Hayes, attended various meetings at
Lightbridge to discuss various sales, marketing, technical and organizational
issues.

     During the week of August 15, 1997, Messrs. Brown, Collins and Pignato and 
Ms. Reeve and representatives of Foley, Hoag & Eliot LLP met with various 
members of Coral's management to continue the financial and legal due diligence.

     Between August 15 and September 9, 1997, financial advisors and legal 
counsel were in frequent contact to negotiate the terms of the Reorganization 
Agreement. On September 2, the Lightbridge board of directors met to discuss 
the proposed merger. Also attending the meeting were representatives of Foley,
Hoag & Eliot LLP and Cowen & Company. The representatives of Cowen & Company
discussed the proposed Merger, providing a transaction overview and summarizing
the due diligence that they had performed, the transaction consideration and
rationale, and the valuation of Coral. After the presentation by Cowen &
Company, the Lightbridge board of directors approved the Reorganization
Agreement and the Merger.

     On September 8, 1997, the Coral board of directors met to consider the
proposed transaction. Also attending the meeting were representatives of
Broadview and Cooley Godward LLP, Coral's outside legal counsel. After a review
and discussion of the proposed transaction, Coral's board of directors approved
the Reorganization Agreement and the Merger.

     On September 9, 1997, Lightbridge, Coral and Acquisition Corp. executed and
delivered the Reorganization Agreement. On September 10, 1997, Lightbridge 
issued a press release announcing the Merger.

CORAL'S REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS OF
CORAL

     On September 8, 1997, the Board of Directors of Coral met and deemed it to
be in the best interests of Coral and its stockholders to enter into the
Reorganization Agreement. In reaching its decision to approve the terms of the
Reorganization Agreement and the Merger, the Board of Directors of Coral
consulted with management of Lightbridge, as well as with its financial and
legal advisors, and considered a number of factors, including the following:

     .    Information concerning Coral's and Lightbridge's respective
          businesses, financial position, historical and prospective results of
          operations, market position, product development plans and technical
          capabilities.

     .    With the assistance of Broadview, information concerning historical
          price and trading volume data for Lightbridge Common and the
          investment attributes of Lightbridge Common. 

     .    The results of efforts by Broadview to solicit acquisition offers from
          potential purchasers other than Lightbridge. Based upon these efforts,
          Coral's Board did not believe that it was likely that additional
          competitive offers from potential acquirors would emerge at that time.

     .    The Coral Board's conclusion that the terms of the Merger were fair, 
          from a financial point of view, to the Coral stockholders based upon
          the present financial condition and business prospects of Coral.

     .    The Coral's Board's consideration of its strategic and financial 
          options, including remaining independent and pursuing Coral's initial
          public offering which was withdrawn early in 1997. In particular, the
          Coral Board considered that Coral would need significant additional
          financing if a merger partner were not obtained and that there was no
          assurance that such additional financing could be obtained by Coral on
          acceptable terms, if at all. The Coral Board also concluded that it
          was unlikely that Coral would be able to complete an initial public
          offering in the foreseeable future.

     .    The importance of market position, scope of product offerings and
          scale of financial resources needed by a company to compete in the
          rapidly consolidating and changing industry environment for wireless
          telecommunications carriers. The Coral Board concluded that an
          affiliation with Lightbridge would provide Coral with increased
          financial, technical, product and managerial resources that will
          become increasingly important in such an industry environment.

     .    The Coral Board's conclusion that the terms of the Merger would
          provide a substantial increase in the liquidity of the investment of
          Coral's stockholders, particularly in light of the Coral Board's
          conclusion that completion of an initial public offering was unlikely.

     .    The fact that the Merger is structured to qualify as a tax-free 
          exchange for federal income tax purposes.

     .    A review with Coral's legal counsel of the terms of the Reorganization
          Agreement and related agreements, particularly the share escrow and
          indemnification provisions of the Reorganization Agreement and the
          Escrow Agreement. As a negative factor, the Coral Board considered the
          fact that a substantial portion of the Merger Consideration would be
          held in escrow following the Closing and, therefore, might not
          eventually be received by the Coral stockholders.

     The Board of Directors of Coral also considered a number of potential risks
relating to the Merger, including (i) the difficulty and management distraction
inherent in integrating the combined company, (ii) the substantial charges 
expected to be incurred by Lightbridge in connection with the Merger, including 
costs of

                                      33
<PAGE>
 
integrating the business and transaction expenses arising from the Merger, 
(iii) the risk that the trading price of Lightbridge Common might be adversely 
affected by the announcement of the Merger, (iv) the risk that the benefits 
sought in the Merger would not be fully achieved, (v) the risk that the Merger 
would not be consummated following the public announcement thereof and (vi) the 
risks of Coral suffering employee attrition and failing to attract key personnel
due to uncertainties associated with the pending Merger. See "Risk Factors."

     The foregoing discussion of the information and factors considered by the 
Board of Directors of Coral is not intended to be exhaustive but is believed to 
include all material factors considered by the Board of Directors of Coral. In 
view of the wide variety of information and factors, both positive and negative,
considered, the Board of Directors of Coral did not find it practical to, and 
did not, quantify or otherwise assign any relative or specific weights to the 
foregoing factors, and individual directors may have given differing weights to 
different factors.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the Coral Board with respect to the 
Reorganization Agreement and the transactions contemplated thereby, Coral 
stockholders should be aware that certain directors and executive officers of 
Coral have certain interests in the Merger.

     As of October 1, 1997, the directors and executive officers of Coral as a 
group beneficially owned an aggregate of 837,542 shares of Coral Common 
(including shares purchasable upon the exercise of outstanding Options and 
Warrants within 60 days of October 1, 1997), 125,000 shares of  Coral Series A 
and 522,500 shares of Coral Series B. All of those shares will be treated in the
Merger in the same manner as the shares of Coral stock held by other
stockholders of Coral. Certain current and former directors of Coral and their
affiliates, who in the aggregate hold a majority of the outstanding Coral Common
and a majority of the outstanding Coral Series A, Coral Series B and Coral
Series C (on an as-converted basis), have executed voting agreements with
Lightbridge pursuant to which they have agreed to vote in favor of the Merger
Proposal and have delivered to Lightbridge irrevocable limited proxies with
respect to the Merger Proposal. Accordingly, those voting agreements and
irrevocable limited proxies are sufficient to effect the approval of the Merger
Proposal. See "Other Matters Related to the Merger--Voting Agreements." To the
best of Coral's knowledge, each of the other Coral directors and executive
officers who owns shares of Coral stock intends to vote those shares in favor of
both the Merger Proposal.

     On September 8, 1997, the Board of Directors of Coral adopted a Management
Bonus Plan pursuant to which certain of Coral's key employees will receive
staying bonuses in an aggregate amount of $220,000 for their continued
employment with Coral through the Closing.  The Management Bonus Plan was
adopted to provide an incentive to those key employees whom the Board of
Directors of Coral believes are integral to the consummation of the Merger.  The
bonuses will be payable within ten days of the Closing.  The key employees 
eligible to receive bonuses under the Management Bonus Plan are Anita Filip, 
John Fraser, Timothy Hayes, Kyle Hubbart and Howard Kaushansky.

     Pursuant to the Reorganization Agreement, two of Coral's executive
officers, John Fraser and Timothy Hayes, will enter into employment agreements
with Coral providing for their continued employment with Coral. Under the
employment agreements, each officer's employment, with Coral may be terminated
by (i) either Coral or Lightbridge, upon sixty days' prior written notice to the
employee; or (ii) the employee, upon written notice to both Coral and
Lightbridge. Neither Mr. Fraser nor Mr. Hayes is entitled to receive
compensation in the event that Coral or Lightbridge terminates his employment
with Coral. The form of the employment agreements is filed as an exhibit to the
Registration Statement and is incorporated herein by reference.

     Persons identified by Coral as "affiliates" (as that term is defined for
purposes of Rule 145 under the Securities Act) of Coral will enter into
agreements restricting sales, dispositions or other transactions reducing their
risk of investment with respect to shares of Coral stock held by them prior to
the Merger and the shares of Lightbridge Common received by them in the Merger
so as to comply with the requirements of applicable federal securities laws.

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
    
     The following discussion summarizes the anticipated material United States
federal income tax consequences of the Merger that are generally applicable to
Lightbridge, Coral and holders of Coral stock under the United States Internal
Revenue Code of 1986, as amended (the "Code"). Coral stockholders should be
aware that this discussion does not deal with all federal income tax
considerations that may be relevant to particular Coral stockholders in light of
their particular circumstances, such as stockholders owning, directly or
indirectly, five percent of more of either the total voting power of the total
value of Lightbridge stock following the Merger; stockholders who are dealers in
securities; stockholders who are subject to the alternative minimum tax
provisions of the Code; and stockholders who are foreign persons, who acquired
their shares in connection with stock option or stock purchase plans or in other
compensatory transactions, or who otherwise hold convertible securities,
warrants or options. In addition, the following discussion does not address the
tax consequences of transactions effectuated prior to or after the Merger
(whether or not such transactions are or were undertaken in connection with the
Merger), including transactions in which shares of Coral Capital Stock were or
are acquired or transactions in which shares of Lightbridge Common are disposed
of. Furthermore, no foreign, state or local tax considerations are addressed
herein.       

     CORAL STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL,
STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER.

     The following discussion is based on the Code, applicable United States
Treasury regulations, judicial authority, and administrative rulings and
practice, all as of the date hereof.  The Internal Revenue Service (the "IRS")
is not precluded from adopting a contrary position.  In addition, there can be
no assurance that future legislative, judicial or administrative changes or
interpretations will not adversely affect the accuracy of the statements and
conclusions set forth herein.  Any such changes or interpretations could be
applied retroactively and could affect the tax consequences of the Merger to
Lightbridge, Coral and their respective stockholders.
    
     At the Closing, as a condition to the obligations of Coral and Lightbridge
to consummate the Merger, Coral stockholders and Lightbridge will receive
opinions from their respective legal counsel, Cooley Godward LLP and Foley, Hoag
& Eliot LLP, to the effect that, while the matter is not wholly free from doubt,
for federal income tax purposes, the Merger will constitute a "reorganization"
within the meaning of Section 368(a) of the Code. The opinions will be based on
certain assumptions and representations and will be subject to limitations and
qualifications as provided in the opinions. As a reorganization, the Merger will
generally result in the following consequences:     

          (a)  No gain or loss will be recognized by holders of Coral Capital
     Stock upon their receipt in the Merger of Lightbridge Common solely in
     exchange for Coral Capital Stock.

          (b)  The aggregate tax basis of the Lightbridge Common received in the
     Merger will be the same as the aggregate tax basis of Coral Capital Stock
     surrendered in exchange therefor.

          (c)  The holding period of the Lightbridge Common received in the
     Merger will include the period for which the Coral Capital Stock
     surrendered in exchange therefor was held, provided that the Coral Capital
     Stock is held as a capital asset at the time of the Merger.
    
          (d)  A Coral stockholder who exercises dissenters' rights with respect
     to a share of Coral Capital Stock and receives payment for such share in
     cash will generally recognize gain or loss for federal income tax purposes,
     measured by the difference between the holder's basis in such share and the
     amount of cash received, provided that the payment is neither essentially
     equivalent to a dividend within the meaning of Section 302 of the Code nor
     has the effect of a distribution of a dividend within the meaning of
     Section 356(a)(2) of the Code (collectively, a "Dividend Equivalent
     Transaction"). Such gain or loss generally will be capital gain or loss,
     provided that the Coral Capital Stock is held as a capital asset at the

                                      35
<PAGE>
 
     time of the Merger. Specifically, it will be long-term capital gain or loss
     if the Coral Capital Stock has been held for more than eighteen months at
     the Effective Time and mid-term capital gain or loss if the Coral Capital
     Stock has been held for more than twelve months but not more than eighteen
     months at the Effective Time. A sale of Coral Capital Stock pursuant to an
     exercise of dissenters' rights will generally not be a Dividend Equivalent
     Transaction if, as a result of such exercise, the stockholder exercising
     dissenters' rights owns no shares of Lightbridge Common (either actually or
     constructively within the meaning of Section 318 of the Code). If, however,
     a stockholder's sale for cash of Coral Capital Stock pursuant to an
     exercise of dissenters' rights is a Dividend Equivalent Transaction, then
     such stockholder may recognize dividend income for federal income tax
     purposes in an amount up to the entire amount of cash so received.       

          (e)  None of Lightbridge, Acquisition Corp. and Coral will recognize
     material amounts of gain or loss solely as a result of the Merger.
    
     The parties have not requested and will not request a ruling from the IRS
in connection with the Merger. The opinions of legal counsel referred to herein
neither bind the IRS nor preclude the IRS from adopting a contrary position. The
opinions are subject to certain assumptions and qualifications and the accuracy
of certain representations made by Lightbridge, Acquisition Corp., Coral and
stockholders of Coral, including representations in certificates to be delivered
to counsel by the respective managements of Lightbridge, Acquisition Corp.,
Coral and by stockholders of Coral. A successful IRS challenge to the
"reorganization" status of the Merger would result in each Coral stockholder
recognizing gain or loss, with respect to each share of Coral Capital Stock
surrendered, equal to the difference between the stockholder's basis in such
share and the fair market value, as of the Effective Time, of the Lightbridge
Common received in exchange therefor. Such gain or loss would be treated as
capital gain or loss for each such stockholder if the Coral Capital Stock was
held as a capital asset at the time of the Merger. In such event, a
stockholder's aggregate basis in the Lightbridge Common so received would equal
its fair market value as of the Effective Time and the stockholder's holding
period for such stock would begin the day after the Merger.
    
     Even if the Merger qualifies as a "reorganization" within the meaning of 
Section 368(a) of the Code, a recipient of shares of Lightbridge Common may
recognize income or gain to the extent that such shares were considered to be
received in exchange for services or property (other than solely Coral Capital
Stock). All or a portion of such income or gain may be taxable as ordinary
income. In addition, gain or loss would be recognized to the extent that a Coral
stockholder was treated as receiving (directly or indirectly) consideration
other than Lightbridge Common in exchange for the stockholder's Coral Capital
Stock.     

     In connection with the Merger, Lightbridge will deposit the escrowed shares
in an escrow account on behalf of the Coral stockholders. See "Other 
Agreements--Escrow Agreement." Pursuant to the Reorganization Agreement, 
escrowed shares will be held to satisfy claims arising out of any 
misrepresentation or inaccuracy in, or breach of, any representation, covenant, 
agreement, warranty, or obligation of Coral contained in the Reorganization 
Agreement, claims for certain monetary payments required to be made by the 
Surviving Corporation after the date of the Closing that arise out of certain 
specified contracts and relate to events occurring or facts existing on or prior
to the date of the Closing, and claims arising out of certain intellectual 
property matters.

     Escrowed shares should be deemed to be owned by the former Coral 
stockholders for federal income tax purposes. Accordingly, any distribution of 
escrowed shares from the escrow to the former Coral stockholders should not be a
taxable event to such stockholders, but they will be taxed on dividends paid, if
any, in respect of the escrowed shares.

     Assuming the Merger is respected as a reorganization, federal income tax 
law is unclear as to the treatment of former Coral stockholders in the event 
that any escrowed shares are used to satisfy any claims under the Reorganization
Agreement. It is possible that satisfaction of such claims with escrowed shares 
will be treated for federal income tax purposes as an adjustment to the 
consideration received by former Coral stockholders in 

                                      36
<PAGE>
 

the Merger, with the result that no gain or loss would be recognized by such
stockholders upon the return of such escrowed shares to Lightbridge.

     There is a risk, however, that the former Coral stockholders will be deemed
to have disposed of such escrowed shares on a proportionate basis and will 
recognize gain or loss on such deemed disposition. In that event, each such 
stockholder would be deemed to have made a payment to Coral in the amount of the
value of such escrowed shares. Such deemed payment could be treated as a cost of
acquiring the shares of Lightbridge Common received in the Merger, which will 
increase the tax basis of such shares.

     Nevertheless, there are also arguments that each former Coral stockholder 
should be allowed a capital loss in an amount equal to the value of the escrowed
shares allocable to such stockholder that are used to satisfy any such claim, 
which loss would be allowable against gain realized on the deemed disposition of
such shares. Coral stockholders should consult their tax advisors on the 
treatment of the use of escrowed shares to satisfy claims under the 
Reorganization Agreement.

ACCOUNTING TREATMENT

     The Merger will be treated as a purchase for financial reporting purposes,
in accordance with generally accepted accounting principles.

FEDERAL SECURITIES LAW CONSEQUENCES
    
     All of the Lightbridge Common issued or issuable in connection with the
Merger, when delivered to Coral stockholders in accordance with the
Reorganization Agreement and the Escrow Agreement, will be freely transferable,
except that any Lightbridge Common received by persons who are "affiliates" (as
such term is defined under the Securities Act) of Coral or Lightbridge prior to
the Merger may be sold by them only in transactions permitted by the resale
provisions of Rule 145 under the Securities Act with respect to affiliates of
Coral or Rule 144 under the Securities Act with respect to persons who are or
become affiliates of Lightbridge, or as otherwise permitted under the Securities
Act. Persons who may be deemed to be affiliates of Coral or Lightbridge
generally include individuals or entities that control, are controlled by, or
are under common control with, such corporation and may include certain officers
and directors of such corporation as well as principal stockholders of such
corporation.     

     Affiliates of Coral or Lightbridge may not sell their shares of Lightbridge
Common acquired in connection with the Merger, except pursuant to an effective
registration under the Securities Act covering such shares or in compliance with
Rule 145 (or Rule 144 under the Securities Act in the case of persons who are or
become affiliates of Lightbridge) or another applicable exemption from the
registration requirements of the Securities Act.  In general, under Rule 145,
for one year following the Effective Time an affiliate (together with certain
related persons) would be entitled to sell shares of Lightbridge Common acquired
in connection with the Merger only through unsolicited "brokers' transactions"
or in transactions directly with a "market maker," as such terms are defined in
Rule 145.  Additionally, the number of shares to be sold by an affiliate
(together with certain related persons and certain persons acting in concert)
within any three-month period for purposes of Rule 145 may not exceed the
greater of one percent of the outstanding shares of Lightbridge Common or the
average weekly trading volume of such stock during the four calendar weeks
preceding such sale.  Rule 145 would only remain available, however, to
affiliates if Lightbridge remained current with its informational filings under
the Exchange Act.  One year after the Effective Time, an affiliate would be able
to sell such Lightbridge Common without such manner of sale or volume
limitations, provided that Lightbridge was current with its Exchange Act
informational filings and such affiliate was not then an affiliate of
Lightbridge.  Two years after the Effective Time, an affiliate would be able to
sell such shares of Lightbridge Common without any restrictions so long as such
affiliate had not been an affiliate of Lightbridge for at least three months
prior thereto.

     Under the Reorganization Agreement, Lightbridge is obligated to file, on
the date of the Closing, a registration statement on Form S-8 with the
Commission covering the shares of Lightbridge Common issuable 

                                      37
<PAGE>
 
upon exercises of the Options and to use its commercially reasonable efforts to
maintain the effectiveness of such registration statement (or file and maintain
the effectiveness of a successor registration statement covering such shares)
for so long as any of the Options remain outstanding.

NASDAQ LISTING
 
     After the Effective Time, Lightbridge will use all reasonable efforts to
cause the shares of the Lightbridge Common to be issued in the Merger, or
issuable upon the exercise of Options and Warrants, to be approved for quotation
on the Nasdaq National Market.

APPRAISAL RIGHTS

     Any holder of Coral shares who objects to the adoption of the
Reorganization Agreement may elect to be paid the fair value of those shares as
determined by the Delaware Court of Chancery. The rights of dissenting holders
of Coral Stock are governed by Section 262 of the Delaware Law. The following
description summarizes the material applicable provisions of Section 262 of the
Delaware Law. The following description is not intended to be a complete
statement of such provisions and is qualified in its entirety by reference to
the full text of Section 262, which is set forth in ANNEX B to this Proxy
Statement/Prospectus.

     If any holder of Coral shares wishes to elect to dissent from the Merger
and demand appraisal, such holder must satisfy each of the following conditions:

          (i)  Such holder must deliver a written demand for appraisal of his,
     her or its shares to Coral, before the taking of the vote with respect to
     the Merger Proposal. This written demand for appraisal must be in addition
     to and separate from any proxy or vote against the Merger Proposal. Merely
     voting against or not voting for the Merger Proposal will not constitute a
     demand for appraisal within the meaning of Section 262.

          (ii) Such holder must not vote in favor of the Merger Proposal. A
     failure to vote will satisfy this requirement, but a vote in favor of the
     Merger Proposal, by proxy or in person, will constitute a waiver of such
     holder's right of appraisal and will nullify any previously filed written
     demand for appraisal. If any holder of Coral shares fails to comply with
     either of these conditions and the Merger becomes effective, such holder
     will have no appraisal rights with respect to such stock.

     All written demands for appraisal by holders of Coral shares should be
delivered to Coral before the taking of the vote on the Reorganization Agreement
at the Special Meeting, and should be executed by, or on behalf of, the holder
of record.  Such demand must reasonably inform Coral of the identity of the
holder and of the intention of the holder to demand the appraisal of such
holder's shares.

     Within ten days after the date of the Merger, the Surviving Corporation
must give written notice that the Merger has become effective to each
stockholder who has filed a written demand for appraisal and who did not vote in
favor of the Merger. Within 120 days after the date of the Merger, either the
Surviving Corporation or any stockholder entitled to appraisal rights under
Section 262 may file a petition in the Delaware Court of Chancery demanding a
determination of the value of the stock of all stockholders entitled to
appraisal. Coral does not presently intend to file such a petition. Inasmuch as
Coral has no obligation to file such a petition, unless at least one dissenting
holder of Coral shares files such a petition within the period specified, the
previous written demands for appraisal of all holders of Coral shares could be
nullified. In any event, at any time within sixty days after the date of the
Merger, any holder who has demanded appraisal of Coral Stock has the right to
withdraw such holder's demand for appraisal.

     Within 120 days after the date of the Merger, any stockholder entitled to
appraisal rights under Section 262 shall be entitled, upon written request, to
receive from the Surviving Corporation a statement setting forth (a) the
aggregate number of shares not voted in favor of the Reorganization Agreement
and with respect to which 

                                      38
<PAGE>
 
demands for appraisal have been received and (b) the aggregate number of holders
of such shares. The Surviving Corporation is required to mail such written
statement to such stockholder within ten days after receipt of the written
request therefor.

     If a petition for appraisal described above is duly filed by a holder of
Coral shares and a copy thereof is served upon the Surviving Corporation, the
Surviving Corporation then will be obligated within twenty days to provide the
Delaware Court of Chancery Register with a duly verified list containing the
names and addresses of all holders of dissenting shares with whom agreement as
to the value of their shares has not been reached.  After notice to such
stockholders, the Court of Chancery is empowered to conduct a hearing upon the
petition in order to determine those stockholders who have complied with Section
262 and who have become entitled to appraisal rights thereunder. The Court may
require the stockholders who demanded payment for their shares to submit their
stock certificates to the Register in Chancery for notation thereon of the
pendency of the appraisal proceedings. If any stockholder fails to comply with
such direction, the Court may dismiss the proceedings as to such stockholder.

     After determination of the stockholders entitled to an appraisal, the Court
of Chancery shall appraise the shares, determining their fair value, exclusive
of any element of value arising from the accomplishment or expectation of the
Merger, together with a fair rate of interest, if any, to be paid upon the
amount determined to be the fair value.  In determining the fair value of the
shares, the Court is to take into account all relevant factors.  In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest the Surviving Corporation would have to pay to
borrow money during the pendency of the proceedings.  When the fair value is
determined, the Court will direct the payment by the Surviving Corporation of
such value, with interest thereon, if any, to the stockholders entitled to
receive the same, upon surrender to the Surviving Corporation by such
stockholders of the certificates representing such stock.

     The costs of the appraisal proceedings may be charged to the parties
thereto (i.e., the Surviving Corporation and the stockholders participating in
the proceeding) by the Court as it deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including reasonable attorneys' fees and the fees and expenses for
experts, to be charged pro rata against the value of all shares entitled to
appraisal. From and after the Effective Time, no stockholder who has demanded
appraisal rights is entitled to vote his shares for any purpose or to receive
payment of dividends or other distributions on his shares (other than with
respect to payment as of a record date prior to the Effective Time), provided,
however, that if no petition for appraisal is filed within 120 days after the
date of the Merger, as provided above, or if such stockholder shall deliver a
written withdrawal of such demand for an appraisal and an acceptance of the
Merger, either within 60 days after the date of the Merger, as provided above,
or thereafter with the written approval of the Surviving Corporation, then the
right of such stockholder to appraisal shall cease.

EXPENSES
    
     In the event the Merger is completed, (a) Lightbridge and Acquisition Corp.
will be and remain responsible for their costs and expenses and (b) the Coral
stockholders will be and remain responsible for their costs and expenses, as
well as the costs and expenses of Coral arising prior to the Closing in
connection with the Merger, except that Lightbridge will be responsible for (i)
a total of $500,000 of fees of Broadview incurred by Coral in connection with
the Merger and (ii) a total of $220,000 payable to five of Coral's key employees
under the Management Bonus Plan described in "The Merger Proposal--Interests of
Certain Persons in the Merger." Any obligations of the Coral stockholders
described in clause (b) above shall be part of the Adjustment Amount and shall
be deemed to be paid by a decrease in the Initial Share Number. See "--
Calculation of Merger Consideration." If the Merger is not consummated,
Lightbridge and Coral will be and remain responsible for their own costs and
expenses, including fees and disbursements of consultants, investment bankers
and other financial advisors, counsel and accountants, and the costs incurred in
seeking necessary consents, in connection with the proposed acquisition of Coral
by Lightbridge.

                                      42
<PAGE>
 
ADDITIONAL COVENANTS

     NO SOLICITATION.  Coral has agreed that it will not, nor will it permit any
of its representatives to, directly or indirectly, (a) solicit, initiate or
participate in discussions or negotiations or otherwise cooperate in any way
with, or provide any information to, any person (other than Lightbridge) or
group of persons concerning any tender offer, exchange offer, merger, business
combination, sale of substantial assets, sale of shares of capital stock or
similar transaction involving such party or (b) enter into any agreement to
effect, or effect, any such transaction (other than the transactions
contemplated hereby). In addition, Coral immediately will notify Lightbridge in
writing of any such proposed transaction.
 
     ACCESS TO INFORMATION; CONFIDENTIALITY.  Prior to the Effective Time, Coral
will afford to Lightbridge, and will cause its independent accountants to afford
to Lightbridge and Lightbridge's accountants, counsel and other representatives,
reasonable access during normal business hours to all of Coral's properties,
books, contracts, commitments and records, as well as all other information
concerning the business, properties and personnel of Coral as Lightbridge may
reasonably request.  Lightbridge, Coral and Acquisition Corp. shall treat as
confidential, and shall cause its accountants, counsel and other representatives
to treat as confidential, all documents and information concerning the other
party furnished by the other party to such party (including documents and
information furnished prior to the date hereof) in connection with the
transactions contemplated by the Reorganization Agreement.

     PUBLIC ANNOUNCEMENTS.  Lightbridge and Coral have agreed that any press
release or other public disclosure of information regarding the transactions
contemplated by the Reorganization Agreement (including the existence and terms
of the Reorganization Agreement) shall be developed by Lightbridge, subject to
the approval of Coral, which approval shall not be unreasonably withheld, and
subject to the obligations of the parties to comply with applicable law.

     OPTIONS AND WARRANTS.  On the date of the Closing, Lightbridge shall file a
registration statement on Form S-8 with the Commission covering the shares of
Lightbridge Common issuable upon exercises of the Options and shall use
commercially reasonable efforts to maintain the effectiveness of such
registration statement (or file and maintain the effectiveness of a successor
registration statement covering such shares) for so long as any of such Options
remain outstanding.  Within fifteen days after the date of the Closing,
Lightbridge will send to each record holder of a Warrant (a) a notice stating
that Lightbridge has assumed the obligations of Coral under such Warrant and
that, as of the Effective Time, such Warrant is exercisable to purchase
Lightbridge Common and (b) an agreement providing that, to the extent not
already contemplated by the terms of such Warrant, as of the Effective Time the
purchase price payable upon any exercise of such Warrant may, at the election of
the record holder of such Warrant, be paid pursuant to a "cashless" exercise, on
the terms set forth in such agreement.

     AGREEMENTS WITH RESPECT TO AFFILIATES. Coral will identify all persons who,

Agreements (as defined in the Reorganization Agreement) on or before the
Closing.

     NASDAQ LISTING. Lightbridge will use its reasonable efforts to cause all of
the shares of Lightbridge Common issuable in the Merger or upon exercise of the
Options and the Warrants after the Effective Time to be approved for quotation
on the Nasdaq National Market.

     INDEMNIFICATION OF CORAL'S OFFICERS AND DIRECTORS. After the Effective
Time, Lightbridge will take no action that would impair any rights to
indemnification that Coral's officers and directors may have under the Coral
Charter or the Coral Bylaws with respect to stockholder claims arising out of
events prior to the Effective Time.

     PATENT INTERFERENCE PROCEEDING.  Coral expects to proceed to pursue its 
rights in the Interference (as defined below). Lightbridge will have the right
to identify the counsel responsible for prosecuting the 

                                      43
<PAGE>
 
Interference on behalf of Coral, subject to the approval of Coral, which
approval shall not be unreasonably withheld. Lightbridge and such counsel will
be responsible for determining the manner in which to proceed in the
Interference, provided, however, that (a) Lightbridge and such counsel will
consult with Coral from time to time and as reasonably requested by Coral and
shall advise Coral of the progress of the Interference and (b) the final form of
the filing with respect to the Interference shall be subject to the approval of
Coral, which consent shall not be unreasonably withheld or delayed. In
connection with the Interference, Coral will (i) render to the Interference
counsel such assistance as such counsel may reasonably request, (ii) make
Coral's attorneys and other representatives available to the Interference
Counsel and (iii) provide the Interference Counsel with copies of all books,
records and other information relating to the patents that are the subject of
the Interference.

     CONSENTS; APPROVALS.  Lightbridge and Coral each will use all commercially
reasonable efforts to obtain any consent, authorization, order or approval of,
or any exemption by, any governmental entity, or other third party, required to
be obtained or made by such party in connection with the taking of any action
contemplated by the Reorganization Agreement. Neither Lightbridge nor Coral
will take any action that would, or is reasonably likely to, result in any of
its representations and warranties set forth in the Reorganization Agreement
being untrue or in any of the conditions precedent set forth in the
Reorganization Agreement not being satisfied. At any time and from time to time
after the closing, Lightbridge and Coral agree to cooperate with each other to
execute and deliver such other documents, instruments or transfer or
assignment, files, books and records, and to do all such further acts and
things, as may be reasonably required to carry out the transactions
contemplated by the Reorganization Agreement.

INDEMNIFICATION

     Under the Reorganization Agreement, subject to the limitations described
below, the Coral stockholders jointly and severally indemnify and agree to
defend and hold harmless Lightbridge and the Surviving Corporation (and their
respective affiliates, officers, directors, employees, representatives and
agents) against and in respect of any and all Damages (as defined in the
Reorganization Agreement) that Lightbridge or the Surviving Corporation (or such
affiliates, officers, directors, employees, representatives and agents) shall
suffer or incur, whether liquidated or unliquidated, accrued or contingent, by
reason of or otherwise arising out of:

     (a)  any misrepresentation or inaccuracy in, or breach of, any
          representation or warranty contained in the Reorganization Agreement,
          in each case as each such representation or warranty would read if all
          qualifications as to materiality were deleted therefrom;

     (b)  any breach of any covenant, agreement or obligation of Coral contained
          in the Reorganization Agreement;

     (c)  certain monetary payments required to be made by the Surviving
          Corporation after the date of the Closing that arise out of certain
          specified contracts and relate to events occurring or facts in
          existence on or prior to the date of the Closing; or

     (d)  certain intellectual property matters.

     The indemnification obligations of the Coral stockholders described in
clauses (a), (b) and (c) above shall survive the Closing and continue for all
Damages as to which Lightbridge has given written notice thereof to the Holder's
Agent, on or prior to the date one year from the date of the Closing; provided,
however, that indemnification obligations of the Coral stockholders for breach
of tax and environmental representations and warranties shall continue until the
expiration of the applicable statutes of limitation and the confidentiality
covenants shall continue until September 9, 2002.  The indemnification
obligations of the Coral stockholders described in clause (d) above shall
survive the Closing and continue for all Damages as to which Lightbridge has
given written notice thereof to the Holders' Agent, on or prior to the date
eighteen month from the date of the Closing.

                                      47
<PAGE>
 
     At the Closing, Lightbridge, Coral, R.D. "Pete" Bloomer, a stockholder and
former director of Coral, as agent for the Coral stockholders (the "'Holders'
Agent"), and the Escrow Agent shall enter into the Escrow Agreement pursuant to
which Lightbridge shall issue to the Escrow Agent the shares of Lightbridge
Common subject to escrow. To the extent any of the indemnified parties may be
entitled to indemnification under the Reorganization Agreement as a result of
any Damages, Lightbridge shall be entitled to set off and apply against such
Damages such escrowed shares in accordance with the terms of the Reorganization
Agreement and the Escrow Agreement. Pursuant to the terms of the Escrow
Agreement, the escrowed shares shall be valued at any time, for purposes of set
off against any Damages, at the Calculation Price. See "Other Agreements--Escrow
Agreement."

     BY APPROVING THE REORGANIZATION AGREEMENT, CORAL STOCKHOLDERS WILL BE 
DEEMED TO HAVE CONSENTED TO THE APPOINTMENT OF R.D. "PETE" BLOOMER TO ACT AS THE
"HOLDER'S AGENT" ON BEHALF OF CORAL STOCKHOLDERS IN CONNECTION WITH THE 
DETERMINATION OF THE ADJUSTMENT AMOUNT, THE INDEMNIFICATION OBLIGATIONS OF THE 
CORAL STOCKHOLDERS UNDER THE REORGANIZATION AGREEMENT, AND THE DEPOSIT AND 
RELEASE OF SHARES PURSUANT TO THE REORGANIZATION AGREEMENT AND THE ESCROW
AGREEMENT.
    
     Notwithstanding the foregoing, the Coral stockholders shall have no
obligation to indemnify Lightbridge or the Surviving Corporation with respect to
the matters described in clauses (a), (b) and (c) above except to the extent
that the aggregate cumulative amount of any Damages with respect to those
matters exceeds $150,000. The Coral stockholders' liability for indemnification
under the Reorganization Agreement or otherwise by reason of or arising out of
any breach by Coral of any covenant that does not survive the Closing or of any
representation or warranty shall be limited as follows: (i) recovery under the
Escrow Agreement with respect to matters described in clauses (a), (b) and (c)
above shall be limited to an aggregate dollar amount equal to ten percent of the
number of escrowed shares, multiplied by the Calculation Price, (ii) recovery
under the Escrow Agreement with respect to matters described in clause (d) above
shall be limited to an aggregate dollar amount equal to the number of escrowed
shares multiplied by the Calculation Price, less the aggregate dollar amount of
any recoveries under the Escrow Agreement with respect to matters described in
clauses (a), (b) and (c) above, and (iii) recovery with respect to any Coral
stockholder shall be limited to an aggregate of the product of the Calculation
Price multiplied by the aggregate number of shares of Lightbridge Common which
such Coral stockholder receives in connection with the Merger.

                               OTHER AGREEMENTS

     Each of the descriptions of the agreements set forth below does not purport
to be complete and is qualified in its entirety by reference to such agreements,
forms of which are filed as exhibits to the Registration Statement and are
incorporated herein by reference.

AFFILIATE AGREEMENTS

     Rule 145 under the Securities Act imposes additional restrictions on the
manner in which persons who are "affiliates" of Lightbridge or Coral within the
meaning of Rules 144 and 145 under the Securities Act may resell securities and
also on the quantity of securities that such affiliates and others with whom
they might act in concert may resell within any three-month period.

     As a condition to the Merger, prior to the Effective Time, each person who
has been identified by Coral as an affiliate of Coral is required to have
entered into an agreement with Lightbridge providing that such person will not
offer to sell or otherwise dispose of any Lightbridge Common obtained as a
result of the Merger except in compliance with the Securities Act and the rules
and regulations thereunder.  Generally, this will require that such sales be
made in accordance with Rule 145(d) under the Securities Act, which in turn
requires that, for specified periods, such sales be made in compliance with the
volume limitations, manner of sale provisions and current information
requirements of Rule 144 under the Securities Act.  The volume limitations
should not pose any material limitations on any Lightbridge stockholder who owns
less than one percent of the outstanding shares of Lightbridge Common after the
Merger unless, pursuant to Rule 144, such stockholder's shares are required to
be aggregated with those of another stockholder.

VOTING AGREEMENTS

     Certain stockholders of Coral (each, an "Approving Holder"), have entered
into voting agreements (each, a "Voting Agreement") with Lightbridge pursuant to
which they have agreed to vote in favor of the Merger Proposal and have
delivered to Lightbridge irrevocable limited proxies with respect to the Merger
Proposal (each, a "Proxy").  Each Proxy provides for the appointment of
representatives of Lightbridge as attorneys and proxy holders of the Approving
Holder with respect to all shares of Coral stock held of record or beneficially
by the Approving Holder.  Each of the proxy holders is empowered at any time
prior to the termination of the Reorganization Agreement to exercise all voting
rights of the Approving Holder in favor of approval of the Reorganization
Agreement and the Merger Proposal at every meeting of Coral stockholders.  Each
of the proxy holders is empowered only to exercise the Proxy to vote the shares
subject thereto in favor of the Reorganization Agreement and the Merger
Proposal. The Approving Holder is entitled to vote the shares subject thereto on
all other matters. Voting Agreements and Proxies have been delivered by each of
the following persons: (i) Bessemer Venture Partners III, L.P., a principal
stockholder of Coral having a representative, David Cowan, on Coral's Board of
Directors; (ii) Cincinnati Bell Information Systems, Inc., a principal
stockholder of Coral having a representative, Robert Marino, on Coral's Board of
Directors; (iii) CVM Equity Fund III, Ltd.,the holder of 34% of the outstanding
shares of Coral Common; (iv) Eric A. Johnson, the former Chairman of the Board
of Directors and Chief Executive Officer of Coral, who delivered his Voting
Agreement and Proxy prior to his resignation from those positions on September
10, 1997; and (v) Vertex Investment (II), Ltd., a principal stockholder of Coral
having a representative, Bruce Graham, on Coral's Board of Directors. See
"Principal Stockholders of Coral."

     The Approving Holders hold, in the aggregate, a majority of the outstanding
Coral Common and a majority of the outstanding Coral Series A, Coral Series B
and Coral Series C (on an as-converted basis).  Accordingly, the Voting
Agreements and Proxies are sufficient to effect the approval of the Merger
Proposal.  See "Other Agreements--Voting Agreements."

ESCROW AGREEMENT

     Under the Reorganization Agreement, subject to the limitations described
below, the Coral stockholders jointly and severally indemnify and agree to
defend and hold harmless Lightbridge and the Surviving Corporation (and their
respective affiliates, officers, directors, employees, representatives and
agents) against and in respect of any and all Damages that Lightbridge or the
Surviving Corporation (or such affiliates, officers, directors, employees,
representatives and agents) shall suffer or incur, whether liquidated or
unliquidated, accrued or contingent, by reason of or otherwise arising out of:

     (a)  any misrepresentation or inaccuracy in, or breach of, any
          representation or warranty contained in the Reorganization Agreement,
          in each case as each such representation or warranty would read if all
          qualifications as to materiality were deleted therefrom;

     (b)  any breach of any covenant, agreement or obligation of Coral contained
          in the Reorganization Agreement;

     (c)  certain monetary payments required to be made by the Surviving
          Corporation after the date of the Closing that arise out of certain
          specified contracts and relate to events occurring or facts in
          existence on or prior to the date of the Closing; or

     (d)  certain intellectual property matters.

     At the Closing, Lightbridge, Coral, the Holders' Agent and the Escrow Agent
shall enter into the Escrow Agreement pursuant to which Lightbridge shall issue
to the Escrow Agent the shares of Lightbridge Common subject to escrow.  The
number of escrowed shares shall equal approximately two-thirds of the Initial
Share Number.  To the extent any of the indemnified parties may be entitled to
indemnification under the Reorganization Agreement as a result of any Damages,
Lightbridge shall be entitled to set off and apply against such Damages such
escrowed shares in accordance with the terms of the Reorganization Agreement and
the Escrow Agreement.  Pursuant to the terms of the Escrow Agreement, the
escrowed shares shall be valued at any time, for purposes of set off against any
Damages, at the Calculation Price.

     The indemnification obligations of the Coral stockholders described in
clauses (a), (b) and (c) above shall survive the Closing and continue for all
Damages as to which Lightbridge has given written notice thereof to the Holders'
Agent on or prior to the date one year from the date of the Closing; provided,
however, that indemnification obligations of the Coral stockholders for breach
of tax and environmental representations and warranties shall continue until the
expiration of the applicable statutes of limitation and the confidentiality
covenants shall continue until September 9, 2002.  The right of indemnified
parties to receive payments under the Escrow Agreement to set off and apply
against any Damages with respect to the matters described in clauses (a), (b) or
(c) above shall be limited to an aggregate dollar amount equal to ten percent of
the Initial Share Number, less the number of shares equal to the Adjustment
Amount divided by the Calculation Price, multiplied by the Calculation Price.
The Coral stockholders shall have no obligation to indemnify Lightbridge or the
Surviving Corporation with respect to the matters described in clauses (a), (b)
or (c) above except to the extent that the aggregate cumulative amount of any
Damages with respect to those matters exceeds $150,000.

     The indemnification obligations of the Coral stockholders described in
clause (d) above shall survive the Closing and continue for all Damages as to
which Lightbridge has given written notice thereof to the Holders' Agent on or
prior to the date eighteen month from the date of the Closing. The right of
indemnified parties to receive payments under the Escrow Agreement to set off
and apply against any Damages with respect to the matters described in clause
(d) above shall be limited to an aggregate dollar amount equal to the number of
escrowed shares multiplied by the Calculation Price.

     Lightbridge will have the right to control the defense or settlement of
claims for indemnification arising in connection with the matters described in
clause (d) above. The Holders' Agent will be entitled to participate in 

                                      50
<PAGE>
 
the defense of those claims, and his consent (which may not be unreasonably
withheld) would be required for any proposed settlement in an amount exceeding
(i) 7.5% of the number of shares of Lightbridge Common issuable in respect of
the outstanding shares of Coral Capital Stock multiplied by (ii) the Calculation
Price. 

     Within fifteen days after the first anniversary of the Closing Date, the
Escrow Agent shall distribute to the Coral stockholders a number of shares of
Lightbridge Common equal to (i) fifty percent of the number of escrowed shares
multiplied by the Calculation Price, less an amount equal to the dollar amount
of all claims as to which a distribution has occurred under the Escrow Agreement
and all pending claims as to which the Holders' Agent has received notice,
 divided by the Calculation Price (as adjusted to reflect any reclassification,
 recapitalization, split up, combination, exchange of shares, readjustment or
 similar action with respect to Lightbridge Common occurring after the Closing
 Date). Within fifteen days after the eighteen-month anniversary of the Closing
 Date, the Escrow Agent shall distribute the remaining escrowed shares to the
 Coral stockholders, less an amount equal to the dollar amount of all pending
 claims as to which the Holders' Agent has received notice. After such date, any
 retained escrowed shares remaining after all pending claims have been resolved
 shall be distributed to the Coral stockholders.

                                 OTHER MATTERS

     As of the date of this Proxy Statement/Prospectus, the management of Coral
does not know of any matters to be presented for consideration at the Special
Meeting, other than the Merger Proposal.  If any other matters properly come

to vote their proxies to the extent entitled in accordance with their best
judgment.

              LIGHTBRIDGE MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   The following discussion and analysis should be read in conjunction with
"Selected Consolidated Financial Data of Lightbridge" and the Consolidated
Financial Statements of Lightbridge and Notes thereto included elsewhere in this
Proxy Statement/Prospectus.  The following discussion contains forward-looking
statements that involve risks and uncertainties, such as statements of
Lightbridge's plans, objectives, expectations and intentions.  In evaluating
such statements, Coral stockholders should consider specifically the risk
factors set forth below and identified elsewhere in this Proxy
Statement/Prospectus, particularly the matters set forth under the caption "Risk
Factors," which could cause Lightbridge's actual results to differ materially
from those indicated by such forward-looking statements.  See "Forward-Looking
Statements."

OVERVIEW

   Lightbridge develops, markets and supports a suite of integrated products and
services that enable wireless telecommunications carriers to improve their
customer acquisition and retention processes.  Lightbridge changed its fiscal
year end from September 30 to December 31, effective with the fiscal year ended
December 31, 1996.  The financial statements for the period ended December 31,
1995 reflect Lightbridge's results of operations for the three months then
ended.  References to fiscal years are to years ended September 30, except that
references to fiscal 1996 are to the year ended December 31, 1996.

   Lightbridge's total revenues increased by 323% from $7.0 million in fiscal
1993 to $29.5 million in fiscal 1996.  Total revenues for the first six months
of 1997 were $17.8 million.  The increase in revenues since 1993 has been driven
primarily by increases in volume of wireless customer qualification and
activation transactions processed for wireless carrier clients and in the
utilization of Lightbridge's products and services by carriers.  Lightbridge's
revenues consist of transaction revenues and software and consulting revenues.
Historically, transaction revenues have accounted for substantially all of
Lightbridge's revenues, although software and consulting revenues have increased
during recent periods primarily as a result of the licensing of certain software
products and the demand for Lightbridge's Business Integration Group's
consulting services.  Software and consulting revenues, which represented no
more than 6.0% of total revenues in each of fiscal 1993, 1994 and 1995,
increased to 25.0% and 32.7% of total revenues in fiscal 1996 and the six months
ended June 30, 1997, respectively.  There can be no assurance that Lightbridge's
software products will achieve market acceptance or that the mix of
Lightbridge's revenues will remain constant.

   Lightbridge's transaction revenues are derived primarily from the processing
of applications of subscribers for wireless telecommunications services and the
activation of service for those subscribers.  Lightbridge has expanded its
offerings from credit evaluation services to include screening for subscriber
fraud, evaluating carriers' existing accounts, interfacing with carrier and
third-party systems, and providing teleservices call center services.  These
services are provided pursuant to contracts with carriers that specify the
services to be utilized and the markets to be served.  Lightbridge's clients are
charged on a per transaction basis.  Pricing varies depending primarily on the
volume of transactions, the type and number of other products and services
selected for integration with the services, and the term of the contract under
which services are provided.  The volume of processed transactions varies,
depending on seasonal and retail trends, the success of the carriers utilizing
Lightbridge's services in attracting subscribers, and the markets served by
Lightbridge for its clients.  Revenues are recognized in the period in which the
services are performed.

   Lightbridge's software and consulting revenues have been derived primarily
from developing customized software and providing Business Integration
consulting services.  Lightbridge also began licensing its Channel Solutions
software with the introduction of its POPS and Iris products in fiscal 1995, its
SAMS software in 1996 and its Retail Management Software in 1997.  Lightbridge's
Channel Solutions products and services are designed to assist customers in
interfacing with Lightbridge's systems and are being marketed primarily to
wireless telecommunications carriers that utilize Lightbridge's transaction
processing services. Lightbridge's Telecommunications Intelligence, formerly
known as Wireless Intelligence, products are being designed to help 

                                      53

carriers analyze the marketplace to improve their business operations. While its
Channel Solutions products and Telecommunications Intelligence products are
licensed as packaged software products, each of these products requires
customization and integration with other products and systems to varying
degrees. Revenues derived from consulting and other projects are recognized
throughout the performance period of the contracts. Revenues from licensing
software are recognized upon the later of delivery of the licensed product or
satisfaction of acceptance criteria. Lightbridge's software and consulting
revenues depend substantially on the continuing need for integration of
disparate systems and acceptance of Lightbridge's software products by
Lightbridge's existing and new clients.

   During fiscal 1994, fiscal 1995 and the three months ended December 31, 1995,
each of Lightbridge's four largest clients, and during fiscal 1996 each of
Lightbridge's two largest clients, accounted for more than 10% of Lightbridge's
total revenues, representing an aggregate of 64%, 63%, 61% and 44% of total
revenues in those periods, respectively. GTE Mobile, which accounted for 31% and
15% of Lightbridge's revenues in fiscal 1995 and fiscal 1996, respectively,
changed the way it accessed Lightbridge's Customer Acquisition System during
fiscal 1996 and terminated its client relationship with Lightbridge as of June
30, 1997. Lightbridge's revenues from GTE Mobile have decreased significantly in
fiscal 1997 as a result of this change. See "Risk Factors--Dependence on Limited
Number of Clients."

   Lightbridge's revenues historically have been derived primarily from sales of
products and services in the United States.

   Beginning in fiscal 1995, Lightbridge increased its sales and marketing
efforts to renew contracts with existing cellular carrier clients and to add new
wireless telecommunications carrier clients, including PCS service providers.
In addition, beginning in fiscal 1995, Lightbridge increased its development
efforts to continue to enhance its existing software and to develop and acquire
new software products and services, including its Channel Solutions and
Telecommunications Intelligence software products and services.  Lightbridge
currently intends to continue to increase its development, sales and marketing
efforts in pursuit of these goals.

   Prior to fiscal 1995, Lightbridge's development activities were focused on
creating software for its outsourcing and service bureau operations.  All
development costs related to these activities were expensed when incurred.  In
fiscal 1995, Lightbridge began developing certain software products to be
licensed as separate products.  In connection with these development efforts,
Lightbridge acquired rights to certain pen-based technology for $400,000, which
has been incorporated in Lightbridge's SAMS product, and certain multimedia
software technology, which has been incorporated in Lightbridge's Iris product.
The multimedia technology was purchased for $45,000 in cash plus an obligation
to pay certain royalties.  In fiscal 1995, Lightbridge capitalized approximately
$980,000 of software costs representing the aggregate of internally developed
products and for the purchase of the aforementioned technology.  Since the
general release of the SAMS and Iris products in fiscal 1995, capitalized
software development costs have been amortized using the straight-line method
over a two-year period.

</TABLE>

SIX MONTHS ENDED JUNE 30, 1997 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1996

   REVENUES.  Revenues increased by 34.4% to $17.8 million in the six months
ended June 30, 1997 from $13.3 million in the six months ended June 30, 1996.
Transaction revenues increased by 12.7% to $12.0 million in the six months ended
June 30, 1997 from $10.7 million in the six months ended June 30, 1996.  The
increase in transaction revenues for the six months ended June 30, 1997 was
primarily due to increased volume of wireless customer qualification and
activation transactions processed for existing carrier clients and additional
new carrier clients.  Software and consulting revenues increased by 123.3% to
$5.8 million in the six months ended June 30, 1997 from $2.6 million in the six
months ended June 30, 1996.  The increase in software and consulting revenues
for the six months ended June 30, 1997 was principally a result of the increase
in revenues attributable to customized software integration services.

   COST OF REVENUES.  Cost of revenues consists primarily of personnel costs,
costs of maintaining systems and networks used in processing subscriber
qualification and activation transactions (including depreciation and
amortization of those systems and networks), and amortization of capitalized
software.  Cost of revenues may vary as a percentage of total revenues in the
future as a result of a number of factors, including changes in the mix of
transaction revenues between revenues from on-line transaction processing and
revenues from processing transactions through Lightbridge's Teleservices Group,
and changes in the mix of total revenues between transaction revenues and
software and consulting revenues.  Cost of revenues increased by 7.2% to $8.3
million in the six months ended June 30, 1997 from $7.8 million in the six
months ended June 30, 1996, while decreasing as a percentage of total revenues
to 46.7% from 58.5%.  The dollar increase in costs for the six months ended June
30, 1997 resulted principally from increases in transaction volume and costs
attributable to expansion of Lightbridge's staff and systems capacity.  The
decrease in cost of revenues as a percentage of total revenues for the six
months ended June 30, 1997 resulted primarily from a higher percentage of
transaction revenues from on-line processing, a higher percentage of revenues
from customized software integration services and licensed software, and
increased utilization of Lightbridge's operating and networking systems.

   DEVELOPMENT.  Development expenses consist primarily of personnel and outside
technical services costs related to developing new products and services,
enhancing existing products and services, and implementing and maintaining new
and existing products and services.  Development expenses increased by 36.1% to
$2.7 million in the six months ended June 30, 1997, from $2.0 million in the six
months ended June 30, 1996, increasing as 

                                      55
<PAGE>
 

a percentage of total revenues to 15.0% from 14.9%. Both the dollar increase and
the increase as a percentage of total revenues for the six months ended June 30,
1997 resulted primarily from the addition of engineering personnel necessary to
support Lightbridge's development programs.

   Lightbridge expects to continue to increase its engineering and development
efforts in order to continue enhancing its existing products and services,
including its Customer Acquisition System, Telecommunications Intelligence,
Business Integration and Channel Solutions products, as well as to develop new
products and services.

   SALES AND MARKETING.  Sales and marketing expenses consist primarily of
salaries, commissions and travel expenses of direct sales and marketing
personnel, as well as costs associated with advertising, trade shows and
conferences.  Sales and marketing expenses increased by 56.4% to $2.6 million in
the six months ended June 30, 1997 from $1.7 million in the six months ended
June 30, 1996, and increased as a percentage of total revenues to 14.6% from
12.6%.  Both the dollar increase and the increase as a percentage of total
revenues for the six  months ended June 30, 1997 were due to the addition of
direct sales and product marketing personnel, increased commissions resulting
from the higher level of revenues and increased use of marketing programs.
Lightbridge continues to invest in sales and marketing efforts in order to
increase its penetration of existing accounts and to add new clients and
markets.

   GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
principally of salaries of administrative, executive, finance and human
resources personnel, as well as outside professional fees.  General and
administrative expenses increased by 81.1% to $2.1 million in the six months
ended June 30, 1997 from $1.2 million in the six months ended June 30, 1996, and
increased as a percentage of total revenues to 11.9% from 8.8%.  Both the dollar
increase and the increase as a percentage of total revenues for the six months
ended June 30, 1997 resulted primarily from increased recruiting fees associated
with the hiring of company personnel and the addition of finance and human
resource personnel.  Lightbridge expects that general and administrative
expenses for the remainder of fiscal 1997 will continue to be incurred at a
higher percentage of total revenues than in the comparable period of fiscal
1996.

   OTHER INCOME (EXPENSE), NET.  Other income (expense) historically has
consisted predominantly of interest income and expense.  Interest expense
consists of interest expense, commitment fees and other similar fees payable
with respect to Lightbridge's bank line of credit, subordinated notes and
capital leases.  Other income (expense) in the six months ended June 30, 1997
consisted predominantly of interest income and expense.  Interest expense
decreased by 53.9% to $0.2 million in the six months ended June 30, 1997 from
$0.4 million in the six months ended June 30, 1996.  Interest income, which
historically had not been significant, increased to $0.6 million during the six
months ended June 30, 1997, as a result of the investment of the proceeds from
Lightbridge's initial public offering in October 1996.

   PROVISION FOR (BENEFIT FROM) INCOME TAXES.  During the six months ended June
30, 1997, a net income tax benefit of $94,000 was derived from the reversal of
Lightbridge's deferred tax asset valuation allowance of $0.7 million, the
utilization of the tax credits, which aggregated $0.4 million, offset by a
provision of $1.0 million.  No significant provision for or benefit from income
taxes was recorded in the six months ended June 30, 1996.

SUPPLEMENTAL DISCUSSION OF FISCAL YEAR ENDED DECEMBER 31, 1996
 COMPARED WITH THE TWELVE MONTHS ENDED DECEMBER 31, 1995

   REVENUES.  Total revenues increased by 45.2% to $29.5 million in the year
ended December 31, 1996 from $20.3 million in the twelve months ended December
31, 1995.  Transaction revenues increased by 17.1% to $22.2 million in the year
ended December 31, 1996 from $18.9 million in the twelve months ended December
31, 1995, primarily due to increased volume of wireless customer qualification
and activation transactions processed for existing carrier clients and, to a
lesser extent, new carrier clients.  Software and consulting revenues increased
to $7.4 million in the year ended December 31, 1996 from $1.4 million in the
twelve months ended December 31, 1995. This increase was attributable to
increased consulting and customized software integration services 

                                      56
<PAGE>
 
provided to both existing and new clients and revenues from Lightbridge's
Channel Solutions products and services. The increase in revenues from
consulting services and customized software integration services in 1996
resulted primarily from projects undertaken for one client, which projects
Lightbridge currently expects will continue at least through the end of 1997.

   COST OF REVENUES.  Cost of revenues increased by 18.0% to $15.4 million in
the year ended December 31, 1996 from $13.1 million in the twelve months ended
December 31, 1995, while decreasing as a percentage of total revenues to 52.2%
from 64.3%.  The dollar increase in costs resulted principally from increases in
transaction volume, costs attributable to expansion of Lightbridge's staff and
systems capacity, and amortization of capitalized software.  The decrease in
cost of revenues as a percentage of total revenues primarily reflected a higher
percentage of transaction revenues from on-line processing than teleservices
operations, a higher percentage of revenues from customized software integration
services and software licenses, and increased utilization of Lightbridge's
operating and networking systems.

   DEVELOPMENT.  Development expenses increased by 5.3% to $4.4 million in the
year ended December 31, 1996 from $4.2 million in the twelve months ended
December 31, 1995, while decreasing as a percentage of total revenues to 14.8%
from 20.4%.  The dollar increase in costs resulted principally from the hiring
of additional personnel to support the continued enhancement of products and
services and the development of new products and services including customized
software integration services, as well as the initial two modules in the
Telecommunications Intelligence suite.  The decrease in development expenses as
a percentage of total revenues reflected the significant growth in Lightbridge's
total revenues.  Lightbridge did not capitalize any software development costs
during the year ended December 31, 1996 and capitalized $535,000 of internally
developed software development costs during the twelve months ended December 31,
1995.

   SALES AND MARKETING.  Sales and marketing expenses increased by 86.7% to $4.2
million in the year ended December 31, 1996 from $2.3 million in the twelve
months ended December 31, 1995, and increased as a percentage of total revenues
to 14.3% from 11.1%.  The increase in costs was due to the addition of direct
sales personnel, increased commissions resulting from the higher level of
revenues, the addition of marketing personnel and increased use of marketing
programs, including trade shows.

   GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased by
4.3% to $2.8 million in the year ended December 31, 1996 from $2.7 million in
the twelve months ended December 31, 1995, and decreased as a percentage of
total revenues to 9.4% from 13.1%.  The dollar increase in general and
administrative expenses resulted from the addition of general and administrative
headcount and other outside services, offset in part by a decrease in legal
costs associated with certain litigation settled in 1996.

   OTHER INCOME (EXPENSE), NET.  Other expense (net) decreased 68.4% to $305,000
in the year ended December 31, 1996 from $965,000 in the twelve months ended
December 31, 1995, principally due to decreased interest expense and increased 
interest income. Interest expense decreased to $754,000 in the year ended
December 31, 1996 from $985,000 in the twelve months ended December 31, 1995.
Interest income, which historically had not been significant, increased to
$422,000 in the year ended December 31, 1996 from $2,000 in the twelve months
ended December 31, 1995 as a result of the investment of proceeds received from
the issuance of Series D convertible preferred stock in April 1996 and
Lightbridge's initial public offering in October 1996.

   PROVISION FOR INCOME TAXES.  The income tax provision was $160,000 for the
year ended December 31, 1996.  Lightbridge had an effective tax rate of 6.6% for
the year ended December 31, 1996, principally due to the application of net
operating loss carryforwards from previous years.  Lightbridge incurred a net
loss for the twelve months ended December 31, 1995 and did not record a benefit
for income tax for the period.  At December 31, 1996, Lightbridge had no
remaining net operating loss carryforwards for federal income tax purposes.

FISCAL YEAR ENDED DECEMBER 31, 1996 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
30, 1995

   REVENUES.  Total revenues increased by 52.7% to $29.5 million in the year
ended December 31, 1996 from $19.4 million in the year ended September 30, 1995.
Transaction revenues increased by 20.4% to $22.2 million in the year ended
December 31, 1996 from $18.4 million in the year ended September 30, 1995,
primarily due to increased volume of wireless customer qualification and
activation transactions processed for existing carrier clients and, to a lesser
extent, new carrier clients.  Software and consulting revenues increased to $7.4
million in the year ended December 31, 1996 from $0.9 million in the year ended
September 30, 1995. This increase was attributable to increased consulting and
customized software integration services provided to both existing and new
clients and revenues from Lightbridge's Channel Solutions products and services.
The increase in revenues from customized software integration services in 1996
resulted primarily from projects undertaken for one client, which projects
Lightbridge currently expects will continue at least through the end of 1997.

   COST OF REVENUES.  Cost of revenues increased by 22.4% to $15.4 million in
the year ended December 31, 1996 from $12.6 million in the year ended September
30, 1995, while decreasing as a percentage of total revenues to 52.2% from
65.2%.  The dollar increase in costs resulted principally from increases in
transaction volume, costs attributable to expansion of Lightbridge's staff and
systems capacity and amortization of capitalized software.  The decrease in cost
of revenues as a percentage of total revenues primarily reflected a higher
percentage of transaction revenues from on-line processing than teleservices
operations, a higher percentage of revenues from customized software integration
services and software licenses and increased utilization of Lightbridge's
operating and networking systems.

   DEVELOPMENT.  Development expenses increased by 13.4% to $4.4 million in the
year ended December 31, 1996 from $3.9 million in the year ended September 30,
1995, while decreasing as a percentage of total revenues to 14.8% from 20.0%.
The increase in dollar costs resulted principally from the hiring of additional
personnel to support the continued enhancement of products and services and the
development of new products and services including customized software
integration services, as well as the initial two modules in the
Telecommunications Intelligence suite.  The decrease in development expenses as
a percentage of total revenues reflected the significant growth in Lightbridge's
total revenues.  Lightbridge did not capitalize any software development costs
during the year ended December 31, 1996 and capitalized $597,000 of internally
developed software development costs during the year ended September 30, 1995.

   SALES AND MARKETING.  Sales and marketing expenses increased by 122.2% to
$4.2 million in the year ended December 31, 1996 from $1.9 million in the year
ended September 30, 1995, and increased as a percentage of total revenues to
14.3% from 9.8%.  The increase in costs was due to the addition of direct sales
personnel, increased commissions resulting from the higher level of revenues,
the addition of marketing personnel and increased use of marketing programs,
including trade shows.

   GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased by
7.1% to $2.8 million in the year ended December 31, 1996 from $2.6 million in
the year ended September 30, 1995, and decreased as a percentage of total
revenues to 9.4% from 13.3%.  The dollar increase in general and administrative
expenses resulted from the addition of general and administrative personnel and
other outside services, offset in part by a decrease in legal costs associated
with certain litigation which was settled in 1996.

   OTHER INCOME (EXPENSE), NET.  Other expense (net) decreased 63.1% to $305,000
in the year ended December 31, 1996 from $826,000 in the year ended September
30, 1995.  Interest expense decreased by 12.7% to $754,000 in the year ended
December 31, 1996 from $864,000 in the year ended September 30, 1995.  Interest
income, which historically had not been significant, increased to $422,000 in
the year ended December 31, 1996 from $38,000 in the year ended September 30,
1995 as a result of the investment of proceeds received from the issuance of
Series D redeemable convertible preferred stock in April 1996 and Lightbridge's
initial public offering of Lightbridge Common in October 1996.

                                      58
<PAGE>
 
   PROVISION FOR INCOME TAXES.  The income tax provision was $160,000 for the
year ended December 31, 1996.  Lightbridge had an effective tax rate of 6.6% for
the year ended December 31, 1996, principally due to the application of net
operating loss carryforwards from previous years.  Lightbridge incurred a net
loss for the year ended September 30, 1995 and did not record a benefit for
income tax for the period.

FISCAL YEAR ENDED SEPTEMBER 30, 1995 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
30, 1994

   REVENUES.  Total revenues increased by 44.4% to $19.4 million in fiscal 1995
from $13.4 million in fiscal 1994.  Transaction revenues increased by 42.6% to
$18.4 million in fiscal 1995 from $12.9 million in fiscal 1994, principally from
increased volume of wireless customer qualification and activation transactions
processed for existing carrier clients. Software and consulting revenues
increased by 91.3% to $947,000 in fiscal 1995 from $496,000 in fiscal 1994,
primarily due to an increase in customized software development for existing
clients.

   COST OF REVENUES.  Cost of revenues increased by 70% to $12.6 million in
fiscal 1995 from $7.4 million in fiscal 1994, and increased as a percentage of
total revenues to 65.2% from 55.3%.  The increase in costs resulted primarily
from increases in transaction volume and increases in personnel costs
attributable to Lightbridge's Teleservices Group and other business operations.
In fiscal 1995, Lightbridge relocated its Teleservices Group to a larger
facility, resulting in increased facilities costs.  Lightbridge made significant
investments in fiscal 1995 in its computing platform, as well as in increased
networking and systems capacity.  The increase in cost of revenues as a
percentage of total revenues reflected continued investment in Lightbridge's
service delivery infrastructure.

   DEVELOPMENT.  Development expenses increased by 66.7% to $3.9 million in
fiscal 1995 from $2.3 million in fiscal 1994, and increased as a percentage of
total revenues to 20% from 17.3%.  The increase in costs was principally
attributable to the hiring of additional personnel to support the continued
enhancement of Lightbridge's existing products and services and the development
of new products and services, including Channel Solutions and Telecommunications
Intelligence products and services.  This increase was offset in part by the
capitalization of $980,000 of software development costs for internally
developed products and for certain purchased technology.  Lightbridge did not
capitalize any software development costs in fiscal 1994.

   SALES AND MARKETING.  Sales and marketing expenses increased by 133.4% to
$1.9 million in fiscal 1995 from $0.8 million in fiscal 1994, and increased as a
percentage of total revenues to 9.8% from 6.1%.  The increase in costs was due
principally to increased commissions resulting from the higher level of
transaction revenues, an increase in sales and marketing personnel and an
increase in recruiting, training and other expenses related to the expansion of
Lightbridge's sales and marketing organization.  The increase was also
attributable to Lightbridge's increased participation in trade shows and
conferences and additional advertising in trade publications.

   GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased by
57.2% to $2.6 million in fiscal 1995 from $1.6 million in fiscal 1994, and
increased as a percentage of total revenues to 13.3% from 12.3%.  The increase
in costs was principally due to hiring of additional personnel to support
Lightbridge's growth and, to a lesser extent, legal costs associated with
certain litigation settled in 1996.

   OTHER INCOME (EXPENSE), NET.  Interest expense increased by 252% to $864,000
in fiscal 1995 from $246,000 in fiscal 1994.  This increase principally
consisted of interest attributable to the issuance of subordinated notes in
August 1995, as well as a higher level of borrowings for working capital
purposes under Lightbridge's bank line of credit.  In addition, interest on
capital leases increased as the result of significant investments in
Lightbridge's infrastructure, which were financed primarily through the leasing
of equipment accounted for as capital leases.

   PROVISION FOR INCOME TAXES.  Lightbridge recorded a net loss in fiscal 1995
and did not record a provision for or benefit from income taxes.  As a result of
Lightbridge's net operating loss carryforwards from previous years, the
provision for income taxes in fiscal 1994 consisted of alternative minimum
taxes.

LIQUIDITY AND CAPITAL RESOURCES

   Prior to its initial public offering, Lightbridge funded its operations
primarily through private placements of equity and debt securities, cash
generated from operations, bank borrowings and equipment financings.

   In October 1996, Lightbridge consummated an initial public offering in which
4,370,000 shares of Lightbridge Common were sold at an initial public offering
price of $10.00 per share.  The total shares consisted of 3,021,868 shares sold
by Lightbridge and 1,348,132 shares sold by certain stockholders of Lightbridge.
Proceeds to Lightbridge, net of underwriting discounts and commissions and
associated costs, were approximately $27.1 million.  These proceeds were used to
repay certain debt obligations of Lightbridge, to repurchase certain shares of
Lightbridge Common, and to fund working capital and other general corporate
purposes.
 
   Prior to its initial public offering, Lightbridge financed its operations in
part with the proceeds of four offerings of convertible preferred stock and two
offerings of subordinated debt.  Lightbridge sold shares of its Series A
redeemable convertible preferred stock in February 1991 for an aggregate
purchase price of $1.0 million, shares of its Series B redeemable convertible
preferred stock in December 1991 for an aggregate purchase price of $1.1 million
and shares of its Series C redeemable convertible preferred stock in June, July
and August of 1993 for an aggregate purchase price of $0.6 million.  In August
1994, Lightbridge sold $2.1 million in principal amount of its 8% subordinated
notes, together with warrants exercisable to purchase up to 525,000 shares of
Lightbridge Common.  In August 1995, Lightbridge sold $1.2 million in principal
amount of its 16% subordinated notes, together with warrants exercisable to
purchase up to 287,750 shares of Lightbridge Common.  Lightbridge sold shares of
its Series D redeemable convertible preferred stock in April 1996 for an
aggregate purchase price of $6.0 million.  A portion of the proceeds of the
Series D redeemable convertible preferred stock was applied to repay the 16%
subordinated notes.

   Lightbridge's capital expenditures in the years ended September 30, 1994 and
1995, the three months ended December 31, 1995, the year ended December 31, 1996
and the six months ended June 30, 1997 aggregated $3.6 million, $3.7 million,
$0.3 million, $2.5 million and $3.5 million, respectively.  The capital
expenditures consisted of purchases of fixed assets, principally for
Lightbridge's services delivery infrastructure, and teleservices call center and
computer equipment for development activities.  Lightbridge leases its
facilities and certain equipment under non-cancelable capital and operating
lease agreements that expire at various dates through December 2004.

   Lightbridge has a $4.0 million working capital line of credit and a $2.0
million equipment line of credit with Silicon Valley Bank.  The working capital
line of credit is secured by a pledge of Lightbridge's accounts receivable,
equipment and intangible assets, and borrowing availability (approximately $3.3
million at June 30, 1997) is based on the amount of qualifying accounts
receivable.  Advances under the working capital line of credit bear interest at
Silicon Valley Bank's prime rate plus .25% (8.50% at December 31, 1996 and 8.75%
at June 30, 1997) and advances under the equipment line of credit bear interest
at Silicon Valley Bank's prime rate plus .75% (9.0% at December 31, 1996 and
9.25% at June 30, 1997).  The working capital line of credit also provides for
the issuance of letters of credit, which reduce the amount Lightbridge may
borrow under the line of credit and are limited to $1,250,000 in the aggregate.
At December 31, 1996 and June 30, 1997, there were no borrowings outstanding
under the working capital line of credit and borrowings of $763,000 and
$611,000, respectively, were outstanding under the equipment line of credit.
The agreements contain covenants that, among other things, prohibit the
declaration or payment of dividends and require Lightbridge to maintain certain
financial ratios which Lightbridge believes are not restrictive to the business
operations.  The working capital line of credit expires in June 1998, and the
equipment line of credit expires in June 1999.
    
   As of June 30, 1997, Lightbridge had cash and cash equivalents of $23.3
million, short-term investments of $1.0 million and working capital of $30.1
million. Lightbridge believes that its current cash balances and the funds
available under its existing lines of credit will be sufficient to fund its cash
obligations in connection with the Merger and to finance Lightbridge's
operations and capital expenditures for at least the next twelve months.

INFLATION

   Although certain of Lightbridge's expenses increase with general inflation in
the economy, inflation has not had a material impact on Lightbridge's financial
results to date.

RECENT ACCOUNTING PRONOUNCEMENTS

   In February 1997, the Financial Accounting Standards Board released Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS 128),
which is effective for fiscal 1997.  SFAS 128 will require Lightbridge to
restate amounts previously reported as earnings per share to comply with the
requirements of SFAS 128.  Lightbridge will adopt SFAS 128 in the fourth quarter
of 1997.  See Note 2 to the Unaudited Condensed Consolidated Financial
Statements of Lightbridge included elsewhere herein.

   In June 1997, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS
130), which is effective for fiscal years beginning after December 15, 1997.
SFAS 130 establishes standards for the reporting and display of comprehensive
income and its components (revenues, expenses, gains and losses) in a full set
of general purpose financial statements.

   In June 1997, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" (SFAS 131), which is effective for periods
beginning after December 15, 1997.  SFAS 131 establishes standards for the way
that public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders.

                            BUSINESS OF LIGHTBRIDGE

   Lightbridge develops, markets and supports a network of integrated products
and services that enable wireless telecommunications carriers to improve their
customer acquisition and retention processes.  Lightbridge's comprehensive
software-based solutions are delivered primarily on an outsourcing and service
bureau basis, which allows wireless carriers to focus internal resources on
their core business activities.  Lightbridge's solutions combine the advantages
of distributed access and workflow management, centrally managed client-
specified business policies, and links to carrier and third-party systems.  The
open architecture underlying Lightbridge's software applications supports the
development of flexible, integrated solutions, regardless of the type of
wireless service provided by a client and independent of the client's computing
environment.

   Lightbridge offers on-line, real-time transaction processing and call center
support solutions to aid carriers in qualifying and activating applicants for
wireless service, as well as software-based sales support services for
traditional distribution channels, such as dealers, agents and direct mobile
sales forces, and emerging distribution channels, such as mass market retail
stores, home shopping and stand-alone kiosks.  Lightbridge develops and
implements interfaces that fully integrate its acquisition system with carrier
and third-party systems, such as those for billing, point-of-sale, activation
and order fulfillment.  Lightbridge recently introduced software-based decision
support tools and services that enable carriers to reduce subscriber churn and
to make more informed business decisions about their subscribers, markets and
distribution channels.

   Lightbridge was incorporated in Delaware in June 1989 under the name Credit
Technologies, Inc.  Effective November 1, 1994, Lightbridge changed its name to
Lightbridge, Inc.  In September 1996, Lightbridge organized a wholly owned
subsidiary, Lightbridge Security Corporation, as a Massachusetts securities
corporation to buy, hold and sell securities.

PRODUCTS AND SERVICES

   Telesto, Lightbridge's network of software-based acquisition and retention
products and services permits a wireless carrier to select applications and
functions to create an integrated, customized solution addressing the carrier's
particular needs.  Lightbridge's products and services are provided by five

CUSTOMER ACQUISITION SYSTEM

   Lightbridge's Customer Acquisition System ("CAS") includes on-line, real-time
transaction processing services for the qualification and activation of
applicants for wireless service.

   CAS accepts applicant information on-line from a variety of carrier
distribution points, such as retail stores.  Upon receipt of information, the
system begins a series of steps required to determine the applicant's
qualification for the carrier's service through inquiry into Lightbridge
proprietary databases, such as ProFile, and external sources, such as credit
bureaus.  The complete applicant file is evaluated by the system and a
determination regarding the applicant's creditworthiness is made based on
centrally managed client-specified business policies.  If an issue is raised
regarding qualification of an applicant, the system electronically routes the
application to a Lightbridge or carrier credit analyst for review and action.
The point-of-sale is then notified when a determination is made.  If service is
to be activated at that time, the system receives, verifies and translates the
information necessary to establish the billing account and activate service,
transmitting data to the carrier's billing and activation systems.  Throughout
the process, Lightbridge's client/server system manages the routing of the
application and the flow of information, both within the system and, as
necessary, to appropriate individuals for their involvement, all in a secure,
controlled environment.

   Introduced in 1989 and enhanced over time, CAS typically enables carriers to
qualify applicants and activate service in five to ten minutes while screening
for subscriber fraud, thereby assisting the carriers to close sales at the time
when the customer is ready to purchase.  Although CAS typically requires no
human intervention beyond the initial data entry, it permits a carrier to
implement policies requiring analyst intervention in carrier-specified
situations.  When intervention is required, CAS facilitates the on-line handling
of exceptions by, among other things, queuing exceptions to manage workflow.
CAS includes the following modules, all of which are fully integrated:

   .  Credit Decision System ("CDS") is an integrated qualification system for
      carriers to acquire qualified applicants rapidly. Using redundant, high-
      speed data lines to five major credit bureaus, CDS typically provides
      consumer and business credit decisions in under 20 seconds, based on
      automated analysis of credit information using a credit policy specified
      by the carrier. CDS can be integrated with a carrier's existing customer
      acquisition and billing systems and can be modified quickly to reflect
      changes in a carrier's credit policies.

   .  Fraud Sentinel is a suite of fraud management tools, available separately
      or together. Lightbridge believes that Fraud Sentinel is the only pre-
      screening tool for detection and prevention of subscription fraud
      available in the wireless industry today. The components of Fraud Sentinel
      are:

          ProFile, a proprietary intercarrier database of accounts receivable
          write-offs and service shut-offs, provides on-line pre-screening of
          applicants, on-going screening of existing subscribers, and
          notification if an application is processed for a subscriber whose
          account has been previously written off by a carrier.

          Fraud Detect, a multifaceted fraud detection tool provided under
          agreement with Trans Union Corporation, analyzes data such as an
          applicant's Social Security Number, date of birth, address, telephone
          number and driver's license information and identifies any
          discrepancies. Fraud Detect became commercially available through
          Lightbridge in the second quarter of 1996.

          Postalpro, a tool to validate addresses, enables a carrier to detect
          false addresses, incorrect ZIP codes and contradictions between
          addresses and ZIP codes before a potential subscriber's service is
          activated. Postalpro became commercially available during the first
          quarter of 1997.

                                      63
<PAGE>
 
   .  InSight is a proprietary database containing information about existing
      accounts and previous applicants. InSight also evaluates existing
      subscribers who apply for additional services on the basis of their
      payment histories. InSight can decrease costs for carriers by reducing the
      number of credit bureau inquiries and the number of applications requiring
      manual review.

                                       59
 
   .  Workstation offerings present data electronically to the appropriate
      person for decision or action and then automatically route data to the
      next step in the process. Workstation offerings are:

          Credit workstation allows a carrier's credit analyst to enter
          information or to evaluate applications that were entered at a remote
          location.

          Activation workstation allows the user to review, correct or reprocess
          activation requests returned from the billing system due to an error.

          Fulfillment workstation provides the information necessary to fulfill
          orders for wireless handsets and accessories at a remote or third-
          party fulfillment operation.

   Pricing of CAS is on a per qualification or activation basis and varies
substantially with the term of the contract under which services are provided,
the volume of transactions, and the other products and services selected and
integrated with the services.

Teleservices

   Lightbridge's Teleservices Group provides a range of call center support
solutions for the subscriber acquisition and activation process.  Lightbridge
first offered a Teleservices call center solution to the wireless marketplace in
1990 with its 800-FOR-CREDIT service.  Since that time, Lightbridge's
Teleservices offerings have expanded to include not only credit decisions and
activations, but also analyst reviews, telemarketing to existing and new
subscribers, back-up and disaster recovery for acquisition and activation
services, and customer care.  Teleservices solutions can be provided using CAS
or a carrier's own customer acquisition system.  Lightbridge's clients typically
utilize Teleservices solutions as part of an overall sales and distribution
strategy to expand or engage in special projects without incurring the overhead
associated with building and maintaining a call center.  Pricing of Teleservices
solutions is on a per transaction basis and varies with the term of the contract
under which services are provided, the volume of transactions processed and the
other products and services selected and integrated with the services.

Channel Solutions

   Lightbridge's Channel Solutions consist of products and services that support
a growing range of distribution channels.  The components of Channel Solutions
include:

   .  POPS, a Windows-based application typically used in carrier-owned or
      dealer/agent store locations, features a graphical user interface that
      allows even inexperienced sales staff to conduct qualification and
      activation transactions quickly via a dial-up or network connection to
      CAS. POPS is being marketed both as a new solution and as a replacement to
      Lightbridge's DOS-based application.

   .  SAMS, a laptop application, provides a "virtual office" for carriers'
      mobile sales professionals. The SAMS suite contains a number of tools
      needed by sales staff, such as coverage maps and product catalogs, as well
      as the ability to handle qualification and activation transactions via
      landline, cellular or wireless data connection to CAS. Third-party modules
      can be integrated into SAMS to provide additional functionality.

                                      64
<PAGE>
 
   .  Iris, an interactive multimedia kiosk, uses touch screen technology to
      provide potential subscribers with educational information ranging from
      the basic operation of a cellular telephone to the form of monthly bills,
      display the carrier's coverage area and provide information about
      available services and telephone models. Iris incorporates a credit card
      reader for payments and allows a customer to purchase a telephone and
      complete an application for service, which can then be processed
      automatically. Iris can dispense a telephone itself or can provide for
      delivery or in-store pick-up.

   .  Retail Management System ("RMS") is a point-of-sale client/server
      application designed to help telecommunications retailers manage the sale
      of telecommunications products more efficiently. RMS 
 
      handles credit screening, transaction and payment processing, service
      activation, cash drawer management, inventory and purchasing management
      and management reporting. RMS became commercially available in the first
      quarter of 1997.

   POPS, SAMS, Iris and RMS are licensed to clients and require customization
and integration with other products and systems to varying degrees.  Pricing of
POPS, SAMS, Iris and RMS varies with the configurations selected, the number of
locations licensed and the degree of customization required.

Telecommunications Intelligence

   Lightbridge's Telecommunications Intelligence Group provides software-based
decision support tools to help carriers analyze their marketplace to improve
business operations.  As carriers encounter increasing competition and a growing
and changing market, Lightbridge believes that the ability to gather, analyze
and interpret business data and then take appropriate actions will be essential
to their success.  Telecommunications Intelligence is currently comprised of the
following two modules:

   .  Channel Wizard allows a carrier to analyze its distribution channel
      performance by market, subscriber type or other factors, to assist the
      carrier in making decisions designed to reduce customer acquisition costs
      and improve channel performance. Channel Wizard is designed to provide up-
      to-date information in a format that is easy for users without statistical
      training to operate. Channel Wizard became commercially available in the
      second quarter of 1996.

   .  Churn Prophet is an analytical tool designed to help carriers reduce churn
      and increase customer retention. Churn Prophet uses predictive modeling
      technology to identify characteristics of subscribers who have canceled
      service in the past and to develop predictions as to which subscribers are
      likely to cancel service in the future. Customer retention efforts can
      then be targeted more cost effectively to the subscribers most likely to
      cancel service. Churn Prophet became commercially available in the fourth
      quarter of 1996, and version 2.0 of Churn Prophet was released in
      September 1997.

   Channel Wizard and Churn Prophet are licensed to clients and require
customization and integration with other products and systems to varying
degrees.  Pricing of Channel Wizard and Churn Prophet varies with the number of
users and the degree of customization required.

   The Telecommunications Intelligence Group also provides a range of consulting
services, including churn analysis and data warehouse design.

Business Integration

   Lightbridge's Business Integration Group provides consulting, software and
tools to link carrier and third-party systems to Lightbridge's systems to enable
those carriers to process qualification and activation transactions through
Lightbridge's systems. To facilitate the development of these interfaces,
Lightbridge developed CAS_COMM, a library of software functions for the remote
host that enables third-party systems to connect to CAS. CAS_COMM is an
application layer protocol that gives CAS the appearance of a local process 

                                      65
<PAGE>
 
to the third-party system. CAS_COMM runs on DEC VMS, Microsoft Windows NT and
certain Unix platforms and supports both TCP/IP and DECnet.

   The Business Integration Group also provides a range of other consulting
services to wireless carriers, employing Lightbridge's expertise and experience
in the wireless telecommunications industry.  For example, the Business
Integration Group helps carriers develop solutions for work flow optimization,
management of bad debt, distribution channel analysis and sales automation.
Lightbridge charges for consulting services on a per diem basis and also
undertakes smaller consulting projects on a fixed-fee basis.

TECHNOLOGY

     Lightbridge's development efforts have created a proprietary multi-layered
software architecture that facilitates the development of application products.
This design conforms to the three standard tiers of presentation (front-ends),
business logic and database services, each independent of the others.  The
architecture supports the development of Lightbridge's core products and
provides a discrete platform that enables the rapid creation of client-specific
requirements.  In addition, the architecture is open in terms of its ability to
interface with third-party systems, as well as with Lightbridge's Windows-based
products.  Lightbridge can therefore offer its clients the ability to use and
enhance legacy systems and third-party systems (such as billing systems) while
implementing the market-oriented products offered by Lightbridge.

     At the most fundamental layer of its architecture, Lightbridge has written
a common, independent library of code that provides a foundation for reusability
and, equally importantly, independence from hardware platforms and operating
systems. The common library currently supports Unix and OpenVMS. The Lightbridge
products are portable and able to run on the most suitable hardware platform for
the computing needs.

     A critical element of Lightbridge's development has been the creation and
enhancement of Allegro, a proprietary peer-to-peer, client/server, transaction
management system.  Allegro encapsulates a sequence of independent, application
servers into a complete transaction, customized for the client's customer
acquisition requirements.  The solutions may include front-end data capture,
customer qualification, fulfillment of physical distribution and connectivity to
back office systems such as billing.  To an individual user, however,
Lightbridge products offer the front-end appearance of a "single virtual
machine." Allegro features include data validation, exception handling, process
queues, manual review queues and transaction monitors.

     Lightbridge servers each perform only a single function, without knowledge
of the other steps in the transaction processes or their computing environment.
Third-party software products are encapsulated so that they are integrated
seamlessly into the Allegro system. As a result, the Allegro network is scalable
and includes software redundancy.

     The wireless marketplace continues to grow rapidly and requires quick
reaction to evolving market conditions.  To meet this requirement, Lightbridge
has incorporated a set of software and tools with which its trained staff can
provide the rapid customization of front-ends, business rules, system interfaces
and reporting.  The customization is independent of the core products, so that
Lightbridge can provide client-specific enhancements while continuing to develop
regular releases of major product enhancements.

CLIENTS

     Revenues attributable to Lightbridge's 10 largest clients accounted for
approximately 90%, 90% and 81% of Lightbridge's revenues in the years ended
September 30, 1994 and 1995 and December 31, 1996, respectively. Four clients
each accounted for greater than ten percent of Lightbridge's total revenues in
the years ended September 30, 1994 and 1995, and two clients each accounted for
more than ten percent of total revenues in the year ended December 31, 1996.
AT&T Wireless Services, Inc. ("AT&T Wireless") accounted for 29% and GTE Mobile
accounted for 15% of Lightbridge's revenues for the year ended December 31,
1996. During 1996, GTE Mobile changed the way it accessed Lightbridge's CAS
during the year ended December 31, 1995, and then 

                                      66
<PAGE>
 
terminated its client relationship with Lightbridge as of June 30, 1997. As a
result, Lightbridge's revenues from GTE Mobile decreased significantly during
fiscal 1996 and the first half of fiscal 1997, before being curtailed completely
as of June 30, 1997. See "Lightbridge Management's Discussion and Analysis of
Financial Condition and Results of Operations--Overview" and Note 2 to
Lightbridge's Audited Consolidated Financial Statements.

     Lightbridge's agreements with its clients set forth the terms on which
Lightbridge will provide products and services for the clients, but do not
typically require the clients to purchase any particular type or quantity of
Lightbridge's products or services or to pay any minimum amount for products or
services.  Lightbridge's agreement with GTE Mobile and certain subsidiaries of
GTE Mobile, which provided that the contract may be terminated by GTE Mobile as
of June 30 of any year upon sixty days' prior notice, was terminated as of June
30, 1997.  Lightbridge has an agreement with AT&T Wireless for the provision of
credit decision services. The agreement will expire on December 31, 1999 unless
it is terminated earlier, upon not less than sixty days' prior written notice.
AT&T Wireless has the right to extend the term of the agreement an additional
two years. The agreement with AT&T Wireless does not require that AT&T Wireless
purchase any particular type or quantity of Lightbridge's products or services,
although it does contain provisions requiring payment of minimum amounts.

SALES AND MARKETING

     Lightbridge's sales strategy is to establish, maintain and foster long-term
relationships with its clients.  Lightbridge's sales and client services
activities are led by "relationship teams," each of which includes a senior
management team sponsor.  Lightbridge employs a team approach to selling in
order to develop a consultative relationship with existing and prospective
clients.  Directors of solutions groups and product managers, as well as other
executive, technical, operational and consulting personnel, are frequently
involved in the business development and sales process.  The teams conduct needs
assessments and, working with the client, develop a customized solution to meet
the client's particular needs.  The sales cycle for Lightbridge's products and
services is typically six to twelve months, although the period may be
substantially longer in some cases.

     Lightbridge expanded its sales and marketing group during 1996 and the
first half of 1997 by hiring additional staff experienced in the wireless
telecommunications industry.

     Lightbridge's marketing activities include public relations, advertising,
participation in industry trade shows and panels, substantive articles in trade
journals and targeted direct mail.

ENGINEERING, RESEARCH AND DEVELOPMENT

     Lightbridge believes that its future success will depend in part on its
ability to continue to enhance its existing product and service offerings and to
develop new products and services to allow carriers to respond to changing
market requirements.  Lightbridge's research and development activities consist
of both long-term efforts to develop and enhance products and services and
short-term projects to make modifications to respond to immediate client needs.
In addition to internal research and development efforts, Lightbridge intends to
continue its strategy of gaining access to new technology through strategic
relationships and acquisitions where appropriate.  Lightbridge spent
approximately $2.3 million, $3.9 million, $4.4 million and $2.7 million on
engineering, research and development in the years ended September 30, 1994,
1995 and December 31, 1996 and the six months ended June 30, 1997, respectively.

COMPETITION

     The market for services to wireless carriers is highly competitive and
subject to rapid change.  The market is fragmented, and a number of companies
currently offer one or more services competitive with those offered by
Lightbridge. In addition, many wireless carriers are providing or can provide,
internally, products and services competitive with those Lightbridge offers.
Trends in the wireless telecommunications industry, including greater
consolidation and technological or other developments that make it simpler or
more cost-effective for wireless 

                                      67
<PAGE>
 
carriers to provide certain services themselves, could affect demand for
Lightbridge's services and could make it more difficult for Lightbridge to offer
a cost-effective alternative to a wireless carrier's own capabilities. In
addition, Lightbridge anticipates continued growth in the wireless carrier
services industry and, consequently, the entrance of new competitors in the
future.

     Lightbridge believes that the principal competitive factors in the wireless
carrier services industry include the ability to identify and respond to
subscriber needs, quality and breadth of service offerings, price and technical
expertise.  Lightbridge believes that its ability to compete also depends in
part on a number of competitive factors outside its control, including the
ability to hire and retain employees, the development by others of products and
services that are competitive with Lightbridge's products and services, the
price at which others offer comparable products and services and the extent of
its competitors' responsiveness to subscriber needs.

     Many of Lightbridge's current and potential competitors have significantly
greater financial, marketing, technical and other competitive resources than
Lightbridge. As a result, Lightbridge's competitors may be able to adapt more
quickly to new or emerging technologies and changes in subscriber requirements
or may be able to devote greater resources to the promotion and sale of their
products and services. There can be no assurance that Lightbridge will be able
to compete successfully with its existing competitors or with new competitors.
In addition, competition could increase if new companies enter the market or if
existing competitors expand their service offerings. An increase in competition
could result in price reductions or the loss of market share by Lightbridge and
could have a material adverse effect on Lightbridge's business, financial
condition, results of operations and cash flow.

     To remain competitive in the wireless carrier services industry,
Lightbridge will need to continue to invest in engineering, research and
development, and sales and marketing. There can be no assurance that Lightbridge
will have sufficient resources to make such investments or that Lightbridge will
be able to make the technological advances necessary to remain competitive. In
addition, current and potential competitors have established or may in the
future establish collaborative relationships among themselves or with third
parties, including third parties with whom Lightbridge has a relationship, to
increase the visibility and utility of their products and services. Accordingly,
it is possible that new competitors or alliances may emerge and rapidly acquire
a significant market share. If this were to occur, Lightbridge's business,
financial condition, results of operations and cash flow could be materially and
adversely affected.

GOVERNMENT REGULATION

     The FCC, under the terms of the Communications Act of 1934, as amended,
regulates interstate communications and use of the radio spectrum.  Although
Lightbridge is not required to and does not hold any licenses or other
authorizations issued by the FCC, the wireless carriers that constitute
Lightbridge's clients are regulated at both the federal and state levels.
Federal and state regulation may decrease the growth of the wireless
telecommunications industry, affect the development of the PCS or other wireless
markets, limit the number of  potential clients for Lightbridge's services,
impede Lightbridge's ability to offer competitive services to the wireless
telecommunications market, or otherwise have a material adverse effect on
Lightbridge's business, financial condition, results of operations and cash
flow.  The Telecommunications Act of 1996, which in large measure deregulated
the telecommunications industry, has caused, and is likely to continue to cause,
significant changes in the industry, including the entrance of new competitors,
consolidation of industry participants and the introduction of bundled wireless
and wireline services.  Those changes could in turn subject Lightbridge to
increased pricing pressures, decrease the demand for Lightbridge's products and
services, increase Lightbridge's cost of doing business or otherwise have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow.


     As a result of offering its ProFile product, Lightbridge is subject to the
requirements of the Fair Credit Reporting Act as well as various state laws and
regulations.  Although Lightbridge's business activities are not otherwise
within the scope of federal or state regulations applicable to credit bureaus
and financial institutions, Lightbridge must take into account such regulations
in order to provide products and services that help its clients 

                                      68
<PAGE>
 
comply with such regulations. Lightbridge monitors regulatory changes and
implements changes to its products and services as appropriate. Although
Lightbridge attempts to protect itself by written agreements with its clients,
failure to reflect the provisions of such regulations in a timely or accurate
manner could possibly subject Lightbridge to liabilities that could have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow.

PROPRIETARY RIGHTS

     Lightbridge's success is dependent upon proprietary technology. Lightbridge
relies on a combination of copyrights, the law of trademarks, trade secrets and
employee and third-party non-disclosure agreements to establish and protect its
rights in its software products and proprietary technology. Lightbridge protects
the source code versions of its products as trade secrets and as unpublished
copyrighted works, and has internal policies and systems designed to limit
access to and require the confidential treatment of its trade secrets.
Lightbridge operates its Credit Decision System software on an outsourcing basis
for its clients. In the case of its Channel Solutions and Telecommunications
Intelligence products, Lightbridge provides the software under license
agreements that grant clients the right to use, but contain various provisions
intended to protect Lightbridge's ownership of and the confidentiality of the
 underlying copyrights and technology. Lightbridge requires its employees and
 other parties with access to its confidential information to execute agreements
 prohibiting unauthorized use or disclosure of Lightbridge's technology. In
 addition, all of Lightbridge's employees are required as a condition of
 employment to enter into non-competition and confidentiality agreements with
 Lightbridge.

     There can be no assurance that the steps taken by Lightbridge to protect
its proprietary rights will be adequate to prevent misappropriation of its
technology or independent development by others of similar technology. It may be
possible for unauthorized parties to copy certain portions of Lightbridge's
products or reverse engineer or obtain and use information that Lightbridge
regards as proprietary. Lightbridge has no patents and existing copyright and
trade secret laws offer only limited protection. Lightbridge's non-competition
agreements with its employees may be enforceable only to a limited extent, if at
all. In addition, the laws of some foreign countries do not protect
Lightbridge's proprietary rights to the same extent as do the laws of the United
States. Lightbridge has been and may be required from time to time to enter into
source code escrow agreements with certain clients and distributors, providing
for release of source code in the event Lightbridge breaches its support and
maintenance obligations, files for bankruptcy or ceases to continue doing
business.

     Lightbridge's competitive position may be affected by limitations on its
ability to protect its proprietary information.  However, Lightbridge believes
that patent, trademark, copyright, trade secret and other legal protections are
less significant to Lightbridge's success than other factors, such as the
knowledge, ability and experience of Lightbridge's personnel, new product and
service development, frequent product enhancements, customer service and ongoing
product support.

     Certain technologies used in Lightbridge's products and services are
licensed from third parties. Lightbridge generally pays license fees on these
technologies and believes that if the license for any such third-party
technology were terminated, it would be able to develop such technology
internally or license equivalent technology from another vendor, although no
assurance can be given that such development or licensing can be effected
without significant delay or expense.

     Although Lightbridge believes that its products and technology do not
infringe on any existing proprietary rights of others, there can be no assurance
that third parties will not assert such claims against Lightbridge in the future
or that such future claims will not be successful.  Lightbridge could incur
substantial costs and diversion of management resources with respect to the
defense of any claims relating to proprietary rights, which could have a
material adverse effect on Lightbridge's business, financial condition, results
of operations and cash flow. Furthermore, parties making such claims could
secure a judgment awarding substantial damages, as well as injunctive or other
equitable relief, which could effectively block Lightbridge's ability to make,
use, sell, distribute or market its products and services in the United States
or abroad. Such a judgment could have a material adverse effect on Lightbridge's
business, financial condition, results of operations and cash flow. In the

                                      69
<PAGE>
 
event a claim relating to proprietary technology or information is asserted
against Lightbridge, Lightbridge may seek licenses to such intellectual
property. There can be no assurance, however, that such a license could be
obtained on commercially reasonable terms, if at all, or that the terms of any
offered licenses will be acceptable to Lightbridge. The failure to obtain the
necessary licenses or other rights could preclude the sale, manufacture or
distribution of Lightbridge's products and, therefore, could have a material
adverse effect on Lightbridge's business, financial condition, results of
operations or cash flow. The cost of responding to any such claim may be
material, whether or not the assertion of such claim is valid.

EMPLOYEES

     As of September 1, 1997, Lightbridge had a total of 319 employees, of which
270 were full-time and 49 were part-time or seasonal.  The number of personnel
employed by Lightbridge varies seasonally.  None of Lightbridge's employees is
represented by a labor union, and Lightbridge believes that its employee
relations are good.

     The future success of Lightbridge will depend in large part upon its
continued ability to attract and retain highly skilled and qualified personnel.
Competition for such personnel is intense, particularly for sales and marketing
personnel, software developers and service consultants.
 
PROPERTIES

     In March 1997 Lightbridge entered into a seven year lease for approximately
46,000 square feet in Burlington, Massachusetts.  In August 1997 Lightbridge
relocated its headquarters from Waltham, Massachusetts to the Burlington
facility, and it currently subleases a portion of the 39,000 square foot
facility in Waltham.  Lightbridge's  teleservices group is located in a 27,000
square foot leased facility, also in Waltham, Massachusetts.  The leases for
both Waltham facilities expire between 1999 and 2001.

(1)  In fiscal 1996 Lightbridge granted to employees options to purchase an
     aggregate of 625,800 shares of Lightbridge Common pursuant to its 1990
     Incentive and Nonqualified Stock Option Plan and options to purchase an
     aggregate of 191,300 shares of Lightbridge Common pursuant to its 1996
     Incentive and Non-Qualified Stock Option Plan.
(2)  All options were granted at fair market value on the date of grant as
     determined by the Compensation Committee, which determined the market value
     of Lightbridge Common based on various factors, including the illiquid
     nature of an investment in Lightbridge Common, Lightbridge's historical
     financial performance and Lightbridge's future prospects.
(3)  Amounts reported in this column represent hypothetical values that may be
     realized upon exercise of the options immediately prior to the expiration
     of their term, assuming the specified compounded rates of appreciation of
     the price of Lightbridge Common over the term of the options. These numbers
     are calculated based on rules promulgated by the Securities and Exchange
     Commission and do not represent Lightbridge's estimate of future stock
     price growth. Any actual gains on stock option exercises and Lightbridge
     Common holdings depend on the timing of such exercise and the future
     performance of Lightbridge Common. There can be no assurance that the rates
     of appreciation assumed in this table will be achieved or that the amounts
     reflected will be received by the Lightbridge Named Executive Officers.
     This table does not take into account any appreciation in the price of
     Lightbridge Common from the date of grant to the current date. The values
     shown are net of the option exercise price but do not include deductions
     for taxes or other expenses associated with the exercise.

EMPLOYMENT AGREEMENT

     In August 1996 Lightbridge executed an employment agreement with Pamela
D.A. Reeve pursuant to which Lightbridge agreed to employ Ms. Reeve as President
and Chief Executive Officer at an initial base salary of $165,000 per year. 
Ms. Reeve's base salary for 1997 is $200,000. The employment agreement is
terminable at will by either party, but if Ms. Reeve's employment is terminated
by Lightbridge for any reason, other than death or disability, within one year
after a change of control of Lightbridge or if Lightbridge terminates Ms.
Reeve's employment at any time without cause, Lightbridge is required to
continue to pay Ms. Reeve's salary for a period of twelve months after such
termination, offset by any amounts received by Ms. Reeve from subsequent
employment during such period.

                   DESCRIPTION OF LIGHTBRIDGE CAPITAL STOCK

     The authorized capital stock of Lightbridge consists of 60,000,000 shares
of Lightbridge Common and 5,000,000 shares of preferred stock, $.01 par value
per share ("Lightbridge Preferred"). As of September 1, 1997 there were
outstanding (i) 15,538,251 shares of Lightbridge Common held by 183 holders of
record and (ii) options to purchase 1,763,292 shares of Lightbridge Common.

     The following summary of certain provisions of Lightbridge Common and
Lightbridge Preferred does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Lightbridge Charter and
applicable law.  See also "Comparison of Stockholders' Rights."

LIGHTBRIDGE COMMON

     Holders of Lightbridge Common are entitled to one vote per share for each
share held of record on all matters submitted to a vote of stockholders. Holders
of Lightbridge Common do not have cumulative voting rights, and therefore the
holders of a majority of the shares of Lightbridge Common voting for the
election of directors may elect all of Lightbridge's directors standing for
election. Subject to preferences that may be applicable to the holders of
outstanding shares of Lightbridge Preferred, if any, the holders of Lightbridge
Common are entitled to receive such lawful dividends as may be declared by the
Board of Directors of Lightbridge. In the event of a liquidation, dissolution or
winding up of the affairs of Lightbridge, whether voluntary or involuntary, and
subject to the rights of the holders of outstanding shares of Lightbridge
Preferred, if any, the holders of shares of Lightbridge Common shall be entitled
to receive pro rata all of the remaining assets of Lightbridge available for
distribution to its stockholders. Lightbridge Common has no preemptive,
redemption, conversion or subscription rights. All outstanding shares of
Lightbridge Common are, and the shares of Lightbridge Common to be issued
pursuant to the Merger will be, fully paid and nonassessable. The issuance of
Lightbridge Common or of rights to purchase Lightbridge Common could have the
effect of making it more difficult for a third party to acquire, or of
discouraging a third party from attempting to acquire, a majority of the
outstanding voting stock of Lightbridge.

LIGHTBRIDGE PREFERRED

     The Board of Directors of Lightbridge is authorized, subject to any
limitations prescribed by Delaware Law, to provide for the issuance of
Lightbridge Preferred in one or more series, to establish from time to time the
number of shares to be included in each such series, to fix the powers,
designations, preferences and relative, participating, optional or other rights,
and the qualifications, limitations or restrictions thereof, of the shares of
each such series and to increase (but not above the total number of authorized
shares of Lightbridge Preferred) or decrease (but not below the number of shares
of such series then outstanding) the number of shares of any such series without
further vote or action by the stockholders.  The Board of Directors of
Lightbridge is authorized to issue Lightbridge Preferred with voting, conversion
and other rights and preferences that could adversely affect the voting power or
other rights of the holders of Lightbridge Common.  Although Lightbridge has no
current plans to issue such shares, the issuance of Lightbridge Preferred or of
rights to purchase Lightbridge Preferred could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
attempting to acquire, a majority of the outstanding voting stock of
Lightbridge.

WARRANTS

     Lightbridge has issued warrants to purchase an aggregate of 847,016 shares
of Lightbridge Common, subject to certain antidilution adjustments. The warrants
to purchase 747,016 shares of Lightbridge Common have an exercise price of $2.00
per share, and the warrants to purchase 100,000 shares of Lightbridge Common
have an exercise of $10.00 per share. All of the warrants are exercisable in
full. The warrants expire on dates between September 1999 and July 2001. The
holders of the warrants are entitled to certain registration rights in respect
of the shares of Lightbridge Common issuable upon exercise of the warrants.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE RESTATED CHARTER AND BY-LAWS AND OF
DELAWARE LAW

     RESTATED CHARTER AND BY-LAWS. The Restated Charter and the Restated By-Laws
contain certain provisions that could discourage potential takeover attempts and
make more difficult attempts by stockholders to change Lightbridge's management.
The Restated Charter authorizes the directors to issue, without stockholder
approval, shares of Lightbridge Preferred in one or more series and to fix the
voting powers, preferences and rights and the qualifications, limitations and
restrictions thereof. The Restated By-Laws provide for the division of the Board
of Directors into three classes as nearly equal in size as possible with
staggered three-year terms. See "Management of Lightbridge." The classification
of the Board of Directors could make it more difficult for a third party to
acquire, or discourage a third party from acquiring, control of Lightbridge. The
Restated Charter provides that stockholders may act only at meetings of
stockholders and not by written consent in lieu of a stockholders' meeting. The
Restated By-Laws provide that nominations for directors may not be made by
stockholders at any annual or special meeting thereof unless the stockholder
intending to make a nomination notifies Lightbridge of its intentions a
specified number of days in advance of the meeting and furnishes to Lightbridge
certain information regarding itself and the intended nominee. These provisions
could delay any stockholder actions that are favored by the holders of a
majority of the outstanding stock of Lightbridge until the next stockholders'
meeting. These provisions may also discourage another person or entity from
making a tender offer for Lightbridge Common, because such person or entity,
even after acquiring a majority of the outstanding stock of Lightbridge, could
only take action at a duly called stockholders' meeting and not by written
consent. The Restated By-Laws also provide that special meetings of
Lightbridge's stockholders may be called only by the President or a majority of
the directors and require advance notice of business to be brought by a
stockholder before any annual or special meeting of stockholders and the
provision of certain information to Lightbridge regarding such stockholder and
others known to be supporting such proposal and any material interest they may
have in the proposed business.

     DELAWARE ANTI-TAKEOVER STATUTE. Lightbridge is subject to Section 203 of
the Delaware Law which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder, unless (i) prior to such date, the board of
directors of the corporation approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder; (ii) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the number of
shares outstanding those shares owned (x) by persons who are directors and also
officers and (y) by employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer; or (iii) on or subsequent
to such date, the business combination is approved by the board of directors and
authorized at an annual or special meeting of stockholders, and not by written
consent, by the affirmative vote of at least two-thirds of the outstanding
voting stock which is not owned by the interested stockholder.

     Section 203 defines "business combination" to include (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition involving the interested stockholder
of 10% or more of the assets of the corporation; (iii) subject to certain
exceptions, any transaction which results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation which has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided by or through the corporation. In
general, Section 203 defines an "interested stockholder" as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person associated with, affiliated with or
controlling or controlled by such entity or person.

LIMITATION OF LIABILITY

     The Restated Charter provides that no director of Lightbridge shall be
personally liable to Lightbridge or to any stockholder for monetary damages
arising out of such director's breach of fiduciary duty, except to the extent
that the elimination or limitation of liability is not permitted by the Delaware
Law.  The Delaware Law, as currently in effect, permits charter provisions
eliminating the liability of directors for breach of fiduciary duty, except that
directors remain liable for (i) any breach of the director's duty of loyalty to
a company or its stockholders, (ii) any acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) any
payment of a dividend or approval of a stock purchase that is illegal under
Section 174 of the Delaware Law or (iv) any transaction from which the director
derived an improper personal benefit.  A principal effect of this provision of
the Restated Charter is to limit or eliminate the potential liability of
Lightbridge's directors for monetary damages arising from breaches of their duty
of care, unless the breach involves one of the four exceptions described in (i)
through (iv) above.  The provision does not prevent stockholders from obtaining
injunctive or other equitable relief against directors, nor does it shield
directors from liability under federal or state securities laws.

     The Restated Charter and the Restated By-Laws further provide for the
indemnification of Lightbridge's directors and officer to the fullest extent
permitted by Section 145 of the Delaware Law, including circumstances in which
indemnification is otherwise discretionary.

STOCK TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for Lightbridge Common is American Stock
Transfer & Trust Company.

                       SELECTED FINANCIAL DATA OF CORAL

   The following selected financial data of Coral for the three years ended
December 31, 1994, 1995 and 1996 and as of December 31, 1995 and 1996 have
been derived from Coral's audited Financial Statements included elsewhere in
this Proxy Statement/Prospectus. The report of Price Waterhouse LLP, independent
accountants for Coral, with respect to those Financial Statements contains an
explanatory paragraph with respect to Coral's recurring losses from operations
and accumulated deficit, which raise substantial doubt about Coral's ability to
continue as a going concern. Selected financial data for the six months ended
June 30, 1996 and 1997 and as of June 30, 1997 have been derived from Coral's
unaudited Financial Statements included elsewhere in this Proxy
Statement/Prospectus. In the opinion of Coral's management, the unaudited
financial information presented reflects all adjustments, consisting only of
normal, recurring adjustments, necessary for a fair presentation of the
financial information for each such period. Operating results for the six months
ended June 30, 1997 are not necessarily indicative of the results that may be
expected for any other interim period or for the year ending December 31, 1997.
This data should be read in conjunction with the Financial Statements of Coral
and Notes thereto and the other financial information of Coral included
elsewhere in this Proxy Statement/Prospectus. See "Coral Management's Discussion
and Analysis of Financial Condition and Results of Operations."

                 CORAL MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   The following discussion and analysis should be read in conjunction with
"Selected Financial Data of Coral" and the Financial Statements of Coral and
Notes thereto included elsewhere in this Proxy Statement/Prospectus.  The
following discussion contains forward-looking statements that involve risks and
uncertainties, such as statements of Coral's plans, objectives, expectations and
intentions.  In evaluating such statements, Coral stockholders should consider
specifically the risk factors set forth below and identified elsewhere in this
Proxy Statement/Prospectus.  See "Forward-Looking Statements."

OVERVIEW

   Coral was founded in 1991 and develops, markets and supports software
solutions for the wireless telecommunications industry.  Prior to the fourth
quarter of 1993, Coral operated as a development stage company with revenue
consisting solely of software development fees.  The report of Price Waterhouse
LLP, independent accountants for Coral, with respect to Coral's Financial
Statements as of December 31, 1995 and 1996 and for the years ended December 31,
1994, 1995 and 1996 contains an explanatory paragraph with respect to Coral's
recurring losses from operations and accumulated deficit, which raise
substantial doubt about Coral's ability to continue as a going concern. See Note
12 to the Financial Statements of Coral.

   Coral did not begin to generate significant revenue until the second quarter
of 1995.  During 1995, 1996 and the six months ended June 30, 1997,
approximately 51.1%, 62.7% and 58.0%, respectively, of Coral's total revenue was
attributable to licenses of FraudBuster, Coral's fraud profiling software
product.  In addition, a significant portion of Coral's service and hardware
revenue for these periods was directly attributable to the licensing of
FraudBuster.

   Coral generates revenue from software licenses, services (including
maintenance, installation and training), development and consulting contracts,
and certain hardware sold in conjunction with software licenses.  Coral's
software license agreements typically provide for an initial license fee and an
annual maintenance fee for a defined number of subscribers, as well as
additional license and maintenance fees for net subscriber additions.  This
provides a potential ongoing revenue stream, which enables Coral to benefit from
growth in the subscriber base of its customers.  Coral also has entered into
license agreements that provide for either a one-time license fee or a monthly
license fee, each of which has an annual maintenance fee with no additional fee
based on incremental subscriber growth.  Revenue from initial license fees with
end users is recognized when the product has been delivered and Coral has
satisfied all significant performance obligations, unless terms of the sales
arrangement provide for customer acceptance that is based on non-standard
performance or other terms.  In the latter case, revenue is recognized when the
customer accepts the product pursuant to those terms.  Revenue for incremental
subscriber growth, if any, is recognized at the date subscriber growth is
calculated and the revenue is earned pursuant to the terms of the relevant
software license agreement.  Monthly license fees are recognized as earned on a
monthly basis.  Maintenance revenue is recognized ratably over the term of the
maintenance agreement.  Service revenue for installation and training is
recognized as the service is performed.  Revenue from development and consulting
contracts is generally recognized as the services are performed, using the
percentage of completion method.  Hardware is sold only in conjunction with
software licenses when required by the customer and such revenue is deferred
until the related license revenue is recognized.

   Coral licenses its software products through a direct sales force,
international sales agents and distributors.  Distributors include vendors of
telecommunications switching equipment, computer hardware and database software.
Sales agreements with distributors typically do not include any rights of return
or provisions for the future adjustment of the selling price.  Coral recognizes
revenue from these transactions at the time the products are shipped to the
distributor, unless payment terms are contingent on the distributor's subsequent
resale or other significant matters. In those latter cases, revenue is not
recognized until the contingencies are resolved. To date, a significant portion
of Coral's revenue in any particular period has been attributable to a limited
number of customers which are comprised of both distributors and wireless 
service providers that purchased products and services directly from Coral.
Coral expects a relatively small number of customers will continue to represent
a 

                                      81
<PAGE>
 
significant percentage of its total revenue for the foreseeable future, although
the companies that comprise the largest customers in any given quarter are
expected to change from quarter to quarter. License revenue from all
distributors accounted for approximately 33.1%, 42.6% and 70.3% of Coral's total
revenue in 1995, 1996 and the six months ended June 30, 1997, respectively.
Revenue from international installations accounted for approximately 34.7%,
16.0% and 25.2% of Coral's total revenue in 1995, 1996 and the six months ended
June 30, 1997, respectively, and Coral expects that international revenue may,
in the future, account for a significant portion of Coral's total revenue.
International revenue is subject to a number of inherent risks, including
increased practical and legal difficulties in accounts receivable collection.

     Cost of software license revenue primarily includes fees paid to third-
party software vendors, as well as costs associated with implementation of the
application software when necessary.  Cost of service revenue consists primarily
of expenses for personnel engaged in customer support, installation, training
and consulting services. Cost of hardware consists of hardware purchased from
third party vendors plus shipping costs.  Coral's gross margin has varied
significantly in the past and may vary significantly in the future, depending
primarily on the mix of services and products licensed or sold by Coral.
Coral's software licenses have a substantially higher gross margin than its
services and hardware revenue.  Therefore, to the extent Coral's total revenue
for any particular period includes a higher proportion of lower margin services
or hardware, there will be an adverse effect on Coral's operating results.

     The sale of Coral's software products to wireless carriers typically
involves a lengthy sales cycle ranging from 6 to 18 months.  The length of the
sales cycle for Coral's products has caused, and may continue to cause, material
fluctuations in Coral's revenue and operating results on a quarterly and annual
basis.  As a result, period-to-period comparisons on a quarterly or annual basis
are not necessarily meaningful and should not be relied upon as indicators of
Coral's future performance.

operations expressed as a percentage of total revenue for the respective

SIX MONTHS ENDED JUNE 30, 1996 AND 1997

     REVENUE.  Total revenue increased 43.5% from $2.6 million in the six months
ended June 30, 1996 to $3.7 million in the six months ended June 30, 1997.

          Software Licenses.  Revenue from software licenses increased 35.1%
     from $2.2 million in the six months ended June 30, 1996 to $2.9 million in
     the six months ended June 30, 1997 and represented 83.7% and 78.8%,
     respectively, of total revenue in these periods. The increase in software
     license revenue for the six months ended June 30, 1997 was primarily
     attributable to revenue from a ChurnAlert license and, to a lesser extent,
     to increased revenue from FraudBuster licenses during this period.

          Services and Other.  Service revenue increased over 200% from $202,000
     in the six months ended June 30, 1996 to $623,700 in the six months ended
     June 30, 1997 and represented 7.8% and 16.8%, respectively, of total
     revenue in these periods. Service revenue was higher in the 1997 period due
     to increased maintenance revenue resulting from an increase in cumulative
     software licenses sold by Coral.

          Hardware.  Hardware revenue decreased from $219,000 in the six months
     ended June 30, 1996 to $162,700 in the six months ended June 30, 1997 and
     represented 8.5% and 4.4%, respectively, of total revenue in these periods.
     The decrease in hardware revenue resulted from a lack of hardware being
     sold in conjunction with new software licenses. The only sale of hardware
     in 1997 was for a hardware upgrade to a customer that originally purchased
     a FraudBuster license and related hardware in 1994.

     COST OF REVENUE.  Cost of revenue was $650,600 and $1,012,300 for the six
months ended June 30, 1996 and 1997, respectively. Overall gross profit as a
percentage of total revenue decreased from 74.9% in the six months ended June
30, 1996 to 72.7% in the six months ended June 30, 1997. This decrease was
primarily attributable to a decrease in software license revenue as a percentage
of total revenue and an increase in service revenue, which contributes a lower
gross margin.

          Software Licenses.  Cost of software licenses increased from $182,000
     in the six months ended June 30, 1996 to $362,600 in the six months ended
     June 30, 1997. Software license gross profit as a percentage of software
     license revenue decreased from 91.6% in the six months ended June 30, 1996
     to 87.6% in the six months ended June 30, 1997. This decrease was primarily
     attributable to higher third-party software costs as a percentage of total
     software license revenue. The increase in third-party software expenses as
     a percentage of total software license revenue was a result of a third-
     party software license upgrade by an existing customer.

          Services and Other.  Cost of services increased from $318,500 in the
     six months ended June 30, 1996 to $490,900 in the six months ended June 30,
     1997, but decreased as a percentage of service revenue from 157.7% in the
     six months ended June 30, 1996 to 78.7% in the six months ended June 30,
     1997. This decrease as a percentage of revenue was due primarily to
     increased maintenance fee revenue resulting from a larger customer base as
     well as more cost efficient customer support operations. In addition,
     during the 1996 period Coral incurred expenses to hire and train personnel
     in anticipation of increased customer installations and future support
     requirements.

          Hardware.  Cost of hardware increased from $150,100 in the six months
     ended June 30, 1996 to $158,800 in the six months ended June 30, 1997, and
     increased as a percentage of hardware revenue from 68.5% in the six months
     ended June 30, 1996 to 97.6% in the six months ended June 30, 1997. This
     increase in the 1997 period was due to Coral's decision to provide a
     hardware upgrade to an existing customer at a nominal margin.

     RESEARCH AND DEVELOPMENT.  Research and development costs primarily consist
of salaries and other personnel-related expenses, supplies, depreciation of
development equipment and third party contract resources used in the development
of Coral's software products.  Research and development expenses increased from
$1.3 million in the six months ended June 30, 1996 to $1.8 million in the six
months ended June 30, 1997, 

                                      83
<PAGE>
 
primarily due to costs related to enhancing existing products and the
development of new products. Research and development expenses represented 49.7%
and 47.6% of total revenue in the six months ended June 30, 1996 and 1997,
respectively. Coral has not capitalized any software costs to date.

     SALES AND MARKETING.  Sales and marketing expenses consist primarily of
salaries and other personnel-related expenses including commissions, promotional
activities, public relations, consulting services and travel expenses related to
sales and marketing activities.  Sales and marketing expenses increased from
$1.5 million in the six months ended June 30, 1996 to $1.6 million in the six
months ended June 30, 1997.  This increase was due to increased sales
commissions resulting from higher levels of revenue, as well as slightly higher
expenses associated with international sales activity and promotional spending.
Sales and marketing expenses represented 57.5% and 44.2% of total revenue in the
six months ended June 30, 1996 and 1997, respectively.

     GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of salaries and other personnel-related expenses, as well as
occupancy, insurance and professional services expenses.  General and
administrative expenses increased from $1.0 million in the six months ended June
30, 1996, to $1.5 million in the six months ended June 30, 1997.  This increase
was primarily due to a severance agreement with an officer of Coral, the
addition of executive management and support personnel, as well as facility
expansion and other related expenses necessary to manage Coral's operations.

     PROVISION (BENEFIT) FOR INCOME TAXES.  Income taxes are accounted for in
accordance with Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes."  Due to Coral's history of pre-tax losses and uncertainty
surrounding the timing of realizing the benefits of its favorable tax
attributes, Coral has recorded a valuation allowance against all of its net
deferred tax assets as of June 30, 1997.

YEARS ENDED DECEMBER 31, 1994, 1995, AND 1996

     REVENUE.  Total revenue increased from $1.4 million in 1994 to $3.9 million
in 1995 and to $8.7 million in 1996, due to significant increases in software
license revenue during such periods.

          Software Licenses.  Software license revenue was $1.0 million, $2.5
     million, and $7.3 million in 1994, 1995 and 1996, respectively. Software
     license revenue consisted primarily of licenses of Coral's FraudBuster
     product in all three years.

          Services and Other.  Service revenue was $239,700, $624,700 and
     $637,700, in 1994, 1995 and 1996, respectively. In 1994 and 1995,
     respectively, service revenue consisted of product development fees for
     both FraudBuster and ChurnAlert of $203,000 and $373,000. The remaining
     service revenue in 1994 and 1995 was primarily from maintenance,
     installation and training fees derived from Coral's software product
     licenses. In 1996 service revenue was derived primarily from maintenance 
     fees and, to a lesser extent, from training and installation fees.

          Hardware.  Hardware revenue was $140,800, $780,500, and $790,800, in
     1994, 1995 and 1996, respectively. The increase in hardware revenue from
     1994 to 1995 was a result of the increase in software license sales.
     Although software license sales continued to grow in 1996, hardware revenue
     in aggregate terms remained relatively flat due to decreased customer
     demand for Coral to provide hardware in conjunction with its software
     product licenses.
    
     COST OF REVENUE.  Cost of revenue was $508,300, $1.9 million and $2.0
million in 1994, 1995 and 1996, respectively.  Overall gross profit as a
percentage of revenue decreased from 64.1% in 1994 to 50.9% in 1995 and
increased to 77.0% in 1996.  Overall gross profit fluctuated as a percentage of
total revenue due to changes in the amount of lower margin service and 
hardware revenue as a percentage of total revenue.     

          Software Licenses.  The cost of software licenses increased from
     $122,000 in 1994 to $526,000 in 1995, and increased to $560,600 in 1996,
     each as a direct result of increased revenue from software licenses.
     Software license gross profit decreased as a percentage of software license
     revenue from 88.2% 

                                      84
<PAGE>
 
     in 1994 to 78.8% in 1995, and increased to 92.3% in 1996. The changes in
     gross profit of software licenses were the result of changes in the average
     license fee of Coral's application software licenses, as well as the cost
     of third party software associated with specific software application
     licenses.

          Services and Other. Cost of services increased from $258,000 in 1994
     to $644,700 in 1995, and increased to $816,000 in 1996. Cost of services as
     a percentage of service revenue decreased from 107.5% in 1994 to 103.2% in
     1995, and increased to 128.0% in 1996. Cost of services in absolute dollars
     increased in 1995 and 1996 due to an increase in customer support personnel
     and related maintenance expenses incurred in anticipation of new customer
     installations and future support requirements.

          Hardware.  Cost of hardware increased from $128,300 in 1994 to
     $738,300 in 1995, and decreased to $617,900 in 1996, primarily due to
     changing levels of hardware sold in conjunction with software licenses.
     Cost of hardware as a percentage of hardware revenue increased from 91.1%
     in 1994 to 94.6% in 1995, and decreased to 78.1% in 1996. The decrease in
     1996 was a result of Coral obtaining significant discounts on larger
     hardware purchases.

     RESEARCH AND DEVELOPMENT.  Research and development expenses were $572,700,
$2.2 million and $2.8 million in 1994, 1995 and 1996, respectively, and
represented 40.4%, 55.5% and 32.1% of Coral's total revenue in such periods.
The increases in absolute dollars in 1995 and 1996 were the result of increased
personnel and related expenses for the enhancement of existing products and the
research and development of new products.

     SALES AND MARKETING.  Sales and marketing expenses were $645,300, $1.9
million and $3.6 million in 1994, 1995 and 1996, respectively, and represented
45.6%, 48.1% and 41.2% of Coral's total revenue in such periods.  Prior to 1994,
Coral relied primarily on reseller and distribution channels for the marketing
and sale of Coral's products.  In late 1994, Coral began building a direct sales
force as well as an infrastructure to manage distribution channels, which
significantly contributed to the increase in sales and marketing expenses.  The
increase in sales and marketing expenses from 1994 to 1995 was a result of
increased personnel and related expenses for Coral's continued development of a
direct sales force and distribution channels, which in 1995 began to expand into
international markets.  The increase from 1995 to 1996 was primarily
attributable to additional personnel and related expenses for selling, marketing
and promotional activities.

     GENERAL AND ADMINISTRATIVE.  General and administrative expenses were
$885,600, $1.4 million and $2.5 million in 1994, 1995 and 1996, respectively,
and represented 62.5%, 34.7% and 29.1% of Coral's total revenue in such periods.
The increase in general and administrative expenses in each period primarily
resulted from increased personnel, facilities, professional services and other
expenses necessary to manage and support Coral's growth.

     STOCK OFFERING COSTS.  During 1996 Coral incurred $676,100 of costs
associated with the filing of a registration statement with the Commission.
Subsequent to December 31, 1996, Coral withdrew its registration statement with
respect to its initial public offering and expensed all related costs.

     PROVISION (BENEFIT) FOR INCOME TAXES.  Coral did not report any tax
provision (benefit) during any of three years ended December 31, 1994, 1995 or
1996.  Coral recorded a valuation allowance against all of its net deferred tax
assets as of each of these respective year ends.

     EXTRAORDINARY GAIN ON EXTINGUISHMENT OF DEBT AND OTHER LIABILITIES.  During
1996 Coral extinguished a previously recorded net liability of $658,300.  Coral
settled the above obligation for $415,000, resulting in a $243,300 extraordinary
gain.  Coral incurred $127,200 in legal fees associated with this transaction
that were included in general and administrative expenses.

LIQUIDITY AND CAPITAL RESOURCES

     Coral has funded its operations to date primarily through the private
placements of equity and debt securities, capital equipment leases, and, to a
lesser extent, bank borrowings.  Since inception, Coral has raised $10.9 million
of gross proceeds from the sale of its capital stock.  Net cash used in
operations for 1994, 1995, 1996, and the six months ended June 30, 1997,
totalled $1.3 million, $3.0 million, $1.5 million and $2.0 million,
respectively.
 
     Net cash used in investing activities for 1994, 1995, 1996, and the six
months ended June 30, 1997, totalled $195,000, $316,000, $522,000 and $478,000,
respectively.  Investment activities have been primarily for the purchase of
hardware and software used in product development, as well as fixtures and
equipment to support Coral's operations.  During 1995, Coral secured a $750,000
capital equipment lease line, all of which has been used.  The lease line
requires monthly payments over three years, commencing from the date of the
funding of each equipment schedule.

     In addition to the capital equipment lease line, Coral has a $750,000 and a
$530,000 revolving variable rate note with a bank.  At June 30, 1997 and
September 25, 1997, Coral had drawn down $500,000 and $740,000, respectively, on
the $750,000 note and had drawn down the full amount of the $530,000 note.  The
$750,000 and $530,000 notes mature on April 26, 1998, and October 22, 1997,
respectively, and provide for monthly interest payments at the bank's prime rate
plus 1.25%, with the principal due at maturity.  The notes are secured by all
cash, accounts receivable, furniture and equipment, inventory and all
transferable third party software rights of Coral.  The amount that can be drawn
on the notes is limited to the sum of 70% of accounts receivable which are no
more than 60 days past due, 50% of the net book value of equipment owned by
Coral, and 50% of the net book value of Coral's inventory.

     Coral may receive, on occasion, advance payments prior to delivery and
acceptance of its products and services.  Such advance payments are treated as
deferred revenue until such time as performance requirements and customer
acceptance are achieved.

     A hardware manufacturer advanced Coral $400,000 in 1992 for the development
of one of Coral's products to operate on the manufacturer's hardware.  Coral has
an agreement with the hardware manufacturer by which Coral earns revenue based
on a percentage of the sales price of the manufacturer's hardware sold by Coral.
Any revenue earned by Coral from the sale of the manufacturer's hardware will
first be applied to this advance.  The $400,000 advance has been recorded as
deferred revenue until earned from the sale of the manufacturer's hardware.  At
June 30, 1997, deferred revenue related to this agreement was $385,000.
    
     As of June 30, 1997, Coral is involved in two matters that could result in
future liabilities to Coral. An interference proceeding has been declared by
the United States Patent and Trademark office between an issued patent and a
patent application of Coral and a patent application by another company (the
"Interference"). Coral's patent and patent application involve certain
technology that is an essential part of its current FraudBuster product. Coral
is currently in negotiations with the other company regarding the Interference;
however, Coral is currently unable to determine whether it will be able to
settle the Interference on terms satisfactory to Coral, the ultimate outcome, or
the range of possible loss in this matter. Coral is also involved in a dispute
in which a customer asserts it is owed approximately $153,000 in past royalties
from Coral. Coral believes it is owed amounts by the customer for services
previously rendered which would fully offset any amount owed to the customer.
Coral is currently unable to predict the ultimate outcome of this uncertainty or
the range of potential loss should an unfavorable outcome occur. The outcome of
these uncertainties could have a material adverse effect on Coral's business,
financial condition, results of operations and cash flow. See Note 10 to the
Financial Statements of Coral.     

     For the six months ended June 30, 1997, Coral incurred a net loss of $2.2
million and experienced net cash outflows of $2.3 million, resulting in a
working capital deficit of $1.6 million at June 30, 1997.  If the Merger is not
consummated, Coral intends to fund its future cash requirements, to the extent
not provided by operations, by seeking additional equity or debt financing while
continuing to pursue other potential business combinations.

                               BUSINESS OF CORAL

     Coral provides client-server software products for the wireless
telecommunications industry to enable carriers to reduce fraud and customer
turnover, or "churn," and increase operating efficiencies.  Coral's products are
based upon its core technology, which provides several key advantages, including
rapid product development, portability, technology independence and enhanced
scalability.  Coral's fraud management software, FraudBuster, includes a fraud
profiler and subscription monitoring techniques and is designed to combat most
currently identified types of wireless fraud.  Unlike many other fraud
prevention techniques, which address specific types of fraud, FraudBuster
detects multiple types of existing and emerging fraud, including cloning,
subscription fraud, tumbling fraud and cellular telephone theft.  Coral's churn
prevention product, ChurnAlert, allows carriers to analyze and identify
potential churn candidates before they seek customer service assistance or
deactivate service.

PRODUCTS

     Coral currently offers two principal products.  FraudBuster, which was
introduced in June 1993, combats most common known types of fraud by tracking
subscriber usage patterns and alerting carrier of suspected fraud.  ChurnAlert,
which was introduced in September 1995, analyzes a carrier's customer base to
identify subscribers likely to discontinue service or churn.

     FRAUDBUSTER.  FraudBuster, Coral's principal product, is a fraud management
software product that includes a fraud profiler and subscription fraud
monitoring functionality and is designed to identify most commonly known types
of wireless fraud (e.g., cloning, subscription, tumbling and cellular theft).
FraudBuster collects subscriber account information and call usage data from
telecommunications switches, billing systems and other commonly accepted data
sources to create individual subscriber profiles that are continuously updated,
referenced and analyzed on a near real-time, call-by-call basis.  In addition,
for enhanced fraud detection FraudBuster monitors usage limits and identifies
suspicious call activity, including simultaneous call attempts, calls to
suspicious locations, abnormally high usage and calls from different cities in
illogical time sequences.  When suspicious account activity occurs, FraudBuster
notifies the carriers with details of the questionable activity and suggests
responses.  FraudBuster addresses the evolving needs of carriers to include more
sophisticated customer care capabilities to proactively manage the impact of
fraud on their subscribers.  For example, FraudBuster can enable the carrier's
billing system to automatically credit subscribers for fraudulent calls charged
to their account before they are invoiced.  By using a client-server
architecture, FraudBuster may be located anywhere on the carrier's premises,
including at the switching center or at the carrier's business offices.
Cellular carriers may locate the servers in a switching center for closer
monitoring and management of the application, with the clients residing in the
departments using the applications.  FraudBuster was introduced in June 1993 and
is now installed in analog, digital and PCS carriers.

     CHURNALERT.  ChurnAlert is a software product that enables carriers to use
adjustable analyses to proactively address the needs of subscribers who are
likely to terminate service, or churn.  Most other currently available churn
products are reactive in that they merely provide information about a subscriber
in response to a query from the customer service representative when the
subscriber calls customer service to deactivate service, which is often too late
to prevent the subscriber from churning.  ChurnAlert collects information from
multiple data sources (e.g., switches and billing systems), analyzes key churn
indicators, such as competitive rate plans and quality of service, and assigns a
probability "value" based on the output of various analyses.  ChurnAlert also
incorporates a customer evaluation feature that permits a user to assign higher
customer care priorities to specific segments of subscribers, such as heavy
users.  ChurnAlert provides carriers visibility to the vulnerability of their
subscriber bases to competitor rate plans and promotions and enables carriers to
model scenarios for other key indicators of churn, such as feature usage and
network quality.  By utilizing a client-server architecture, ChurnAlert may be
located anywhere on the carrier's premises.  For example, cellular carriers may
locate the servers in a switching center for closer monitoring and management of
the application, with the clients residing in the departments using the
applications.  ChurnAlert was introduced in September 1995.

PRODUCT DEVELOPMENT

     Coral believes that its future success will depend on its ability to
maintain and improve its current technologies, enhance its existing products and
develop new products that meet an expanding range of carrier requirements. At
June 30, 1997, Coral's development staff consisted of 27 employees. For 1994,
1995 and 1996 and the six months ended June 30, 1997, Coral's expenditures on
research and development were $572,700, $2.2 million, $2.8 million and $1.8
million, respectively. To date, Coral has not capitalized any software
development costs.

     Coral's success depends in part on the timely introduction and success of
new products or product enhancements.  A significant delay in the introduction
of, or the presence of a defect in, one or more new products or product
enhancements could have a material adverse effect on the ultimate success of
such products or product enhancements and on Coral's business, operating results
and financial condition.  Further, because of the revenue typically associated
with initial shipments of a new product or product enhancement, delaying the
introduction of a new product or product enhancement expected near the end of a
fiscal quarter may materially adversely affect operating results for that
quarter or beyond.  The process of developing software products such as those
offered by Coral is extremely complex and is expected to become more complex and
expensive in the future as new platforms and technologies emerge.  In the past,
Coral has experienced significant delays in the introduction of certain new
products and product enhancements and Coral anticipates that there will be
similar delays in developing and introducing new products and product
enhancements in the future.  There can be no assurance that new products or
product enhancements will be introduced on schedule or at all or that they will
achieve market acceptance or generate significant revenue.  Software products as
complex as those offered by Coral may contain undetected errors when first
introduced or when new versions are released.  There can be no assurance that,
despite testing by Coral, errors will not be found in new products or product
enhancements after commencement of commercial shipments, resulting in loss of or
delay in market acceptance, which could have a material adverse effect on
Coral's business, operating results and financial condition.

TECHNOLOGY

     Coral's products are based upon its core technology, which provides several
key development advantages, including enabling Coral to quickly develop new
applications, to rapidly port Coral's applications to alternative third party
software platforms and to offer carriers technology-independent solutions that
are scalable for rapid growth.  Coral's core technology allows new applications
to be built by using applets and services that were developed for previous
releases of other applications.  An "applet" is a self-contained mini-
application that provides complete application functionality for a given task.
This strategy permits consistent re-use of applets and services reducing the
amount of code that it must develop and maintain, enabling rapid development of
new applications and improving the quality of the code through reuse.  In
addition, the flexibility of Coral's core technology will enable Coral to reduce
the development time for native language versions of its existing products for
use in foreign countries.  Coral has encapsulated many of the external links of
its core technology in order to insulate it from changes or obsolescence of
third party hardware and software.  Coral's core technology provides enhanced
scalability to permit the rapid and efficient growth of the wireless subscriber
bases and the deployment of new software technologies.  Coral believes that
these features (rapid development, portability, protection against technology
obsolescence and enhanced scalability) provide carriers with a significant
development advantage in integrating evolving technologies into Coral's products
for increased application efficiency and performance.  Coral's core technology
operates on Hewlett-Packard and Sun Microsystems hardware platforms, and
includes interfaces to Oracle and Informix databases, allowing for flexible
configuration to each customer's environment.  In addition, the core technology
enables Coral to offer applications that support all air interfaces and IS-41
and GSM network protocols, permitting multi-national wireless carriers to
utilize Coral's products in diverse technology and standards settings.

SALES, MARKETING AND DISTRIBUTION

     Coral markets its products to cellular, PCS and other wireless carriers
domestically and internationally. Products are distributed through Coral's
direct sales force, international sales agents and distributors. Coral licenses
its products pursuant to agreements that typically provide for an initial
license fee and annual maintenance for a defined number of subscribers, as well
as additional license and maintenance fees for net subscriber additions. Coral's
products typically require a significant investment by the carrier and involve
multilevel testing, integration, implementation and support requirements. As a
result, product sales cycles generally range from 6 to 18 months.
     
     The end users of Coral's products are domestic and international wireless
telecommunications providers. Revenue from international installations accounted
for approximately 27.2%, 34.7%, 16.0% and 25.2% of Coral's total revenue in
1994, 1995, 1996 and the six months ended June 30, 1997, respectively, and Coral
expects that international revenue will continue to account for a significant
portion of Coral's total revenue. Coral expects to expand its sales efforts
outside of the U.S., which will require significant management attention and
financial resources. International revenue is subject to inherent risks,
including unexpected changes in regulatory requirements, tariffs and other trade
barriers, political and economic instability in foreign markets, difficulties in
staffing and management and integration of foreign operations, longer payment
cycles, greater difficulty in accounts receivable collection, currency
fluctuations and potentially adverse tax consequences. Since most of Coral's
foreign sales are denominated in U.S. dollars, Coral's products may also become
less price competitive in countries in which local currencies decline in value
relative to the U.S. dollar.     

CUSTOMERS AND CUSTOMER SUPPORT
    
     Lucent Technologies accounted for 49.3% and 47.3% of Coral's total revenue
in 1996 and the six months ended June 30, 1997, respectively.     

     Coral provides its customers with support including project management,
database navigation and trouble shooting, product training, technical expertise
in network communications and interface development, as well as hardware and
software installation skills.  As part of its standard maintenance services,
Coral provides support services five days a week, eight hours per day, via
telephone, remote login, e-mail, and, if necessary, on-site assistance.  Coral
offers a range of support packages for additional fees, including support seven
days a week, 24 hours per day.  Coral also offers consulting services to its
customers for a separate fee.

COMPETITION

     The markets for Coral's software products are new, intensely and
increasingly competitive, rapidly evolving and subject to rapid technological
change.  Coral's competitors include computer hardware and software providers,
telecommunications services and billing providers and range from small companies
with limited resources to large companies with substantially greater financial,
technical and marketing resources than those of Coral.  In addition, Coral
competes against the internal development efforts of Coral's customers and
potential customers.  As a result, some of Coral's competitors may be able to
adapt more quickly to new or emerging technologies and changes in customer
requirements, or to devote greater resources to the promotion and sale of their
products than Coral.  Further, existing companies may broaden their product
lines or increase their focus to compete more directly with Coral's current and
future products.  Currently, Coral's principal competitors are GTE-TSI in the
United States and Digital Equipment Corporation in international markets.
Coral's FraudBuster product competes with a number of other profiler products
and several alternative technologies, including RF signature systems, PINs and
authentication.  In addition, Coral has licensed the source code for FraudBuster
to AirTouch for the purpose of enabling AirTouch to use, reproduce and develop
enhancements to FraudBuster in AirTouch's markets and to sublicense FraudBuster
to cellular carriers in which AirTouch directly owns at least a 10% equity
interest, in exchange for a royalty to Coral on such sublicenses.  As a result,
AirTouch could compete with Coral in those markets covered by cellular carriers
in which AirTouch owns such an equity interest.  GTE-TSI is also Coral's primary
competitor in the churn prevention software market.  To the extent that
competitors achieve higher product quality, lower price, greater functionality
or other advantages relative to Coral's products, Coral's business, operating
results and financial condition could be materially and adversely 

                                      89
<PAGE>
 
affected. There can be no assurance that Coral will have the resources required
to respond effectively to market or technological changes or to compete
successfully in the future. Furthermore, increasing competition in the wireless
telecommunications industry may cause prices to fall, which may materially and
adversely affect Coral's business, operating results, financial condition and
cash flow.

     Current and potential competitors have established or may in the future
establish cooperative relationships among themselves or with third parties to
increase the ability of their products to address the needs of Coral's
prospective customers.  Accordingly, it is possible that new competitors or
alliances may emerge and rapidly acquire significant market share.  If this were
to occur, Coral's business, operating results, financial condition and cash flow
would be materially adversely affected.

INTELLECTUAL PROPERTY

     Coral regards its software as proprietary and relies primarily on a
combination of patent, trademark, copyright and trade secret laws, employee and
third-party nondisclosure agreements and other methods to protect its
proprietary rights.  Coral currently has two issued U.S. patent and five
applications pending in the U.S. Patent and Trademark Office, six applications
for foreign patents pending and four Patent Cooperation Treaty applications
preserving Coral's ability to obtain patent protection in a number of foreign
countries.  There can be no assurance that any of such pending patent
applications will result in the issuance of any patents, or that Coral's current
patent or any future patents will provide meaningful protection to Coral.  In
particular, there can be no assurance that third parties have not or will not
develop equivalent technologies or products that avoid infringing Coral's
current patent or any future patents or that Coral's current patent or any
future patents would be held valid and enforceable by a court having
jurisdiction over a dispute involving such patents.  In addition, since patent
applications in the United States are not publicly disclosed until the patent
issues and foreign patent applications generally are not publicly disclosed for
at least a portion of the time that they are pending, applications may have been
filed by entities other than Coral which, if issued as patents, may relate to
Coral's products.  There can be no assurance that third parties will not assert
infringement claims against Coral in the future based on existing patents or
future patents or that such claims will not be successful.

     Coral does not include in its products any mechanism to prevent or inhibit
unauthorized copying.  Unauthorized copying is common within the software
industry, and if a significant amount of unauthorized copying of Coral's
products were to occur, Coral's business, operating results, financial condition
and cash flow could be materially and adversely affected.  Furthermore, Coral
may enter into transactions in countries where intellectual property laws are
not well developed and where legal protection of Coral's rights may be
ineffective.  Also, as the number of software products in the industry
increases, and the possibility for overlapping functionality increases, software
developers may increasingly become subject to infringement claims.  There can be
no assurance that third parties will not assert infringement claims against
Coral with respect to current or future products.  From time to time, Coral
receives notices from third parties claiming infringement of intellectual
property rights of such parties.  Coral investigates these claims and responds
as it deems appropriate.  However, there can be no assurance that Coral's
response will satisfy the party sending the notice, or that such party will not
institute a claim against Coral.  The scope of protection accorded to patents
covering software-related inventions is evolving and is subject to a significant
degree of uncertainty.  Any claims or litigation, with or without merit, could
be costly, time-consuming and could result in a diversion of management's
attention, which could have a material adverse effect on Coral's business,
operating results, financial condition and cash flow.  In addition, such claims
could cause product shipment delays or require Coral to enter into royalty or
licensing agreements which may not be available on terms acceptable to Coral or
at all, any of which could have a material adverse effect on Coral's business,
operating results,  financial condition and cash flow.  There has been
substantial litigation regarding copyright, trademark and other intellectual
property rights involving computer software companies and there can be no
assurance that Coral will not be subject to litigation regarding these matters
in the future.  Adverse determinations in such claims or litigation could also
have a material adverse effect on Coral's business, operating results, financial
condition and cash flow.

     One of Coral's issued U.S. patents relates to specific aspects of its fraud
detection and profiling technology, including aspects that have been or may in
the future be used in FraudBuster or other Coral products.  Coral filed

                                      90
<PAGE>
 
a continuation application for this issued patent to pursue additional claims.
Coral received notice from the United States Patent and Trademark Office that
the issued patent and the continuation application are the subject of the
interference, in which Coral has been determined to be the junior party.

     Interference actions may be complex and expensive, and the outcome of such
actions is often difficult to predict.  Accordingly, Coral is considering
opportunities to settle the interference action on terms acceptable to Coral.
Any such settlement may require paying royalty fees and/or licensing of Coral's
patent rights which may diminish their value to Coral.  In addition, there can
be no assurance that Coral will pursue a settlement or that a settlement would
be reached on terms acceptable to Coral.  In the event that Coral could not
settle any such interference action and were declared to lose the interference,
it could lose some or all of the claims in Coral's existing patent and/or the
continuation application and be subject to patent infringement claims for its
use of the technology in question.  Any such action or claim could have a
material adverse effect on Coral's business, operating results, financial
condition and cash flow.

     Coral recently has settled an alleged trademark infringement matter with
Tadiran Telecommunications regarding Coral's use of the name "Coral Systems,
Inc."  The settlement, among other things, provides that in exchange for a one-
time payment, Coral shall take reasonable steps to clarify any actual confusion
regarding its use of the name "Coral Systems, Inc." and shall enter binding
arbitration to alleviate any such confusion (although the award of any
arbitration cannot require Coral to cease using the name "Coral Systems, Inc.").

EMPLOYEES

     As of September 1, 1997, Coral had 67 employees, including 24 in research
and development, 8 in customer support, 8 in domestic sales, 3 in international
sales, 2 in consulting services, 8 in marketing, and 14 in finance and
administration.  Coral also retains consultants from time to time to assist it
with particular software development projects.  Coral believes that its future
success will depend in part on its ability to attract, motivate and retain
highly qualified personnel.  None of Coral's employees is represented by a
collective bargaining agreement, nor has Coral experienced any work stoppage.
Coral considers its employee relations to be good.

FACILITIES

     Coral currently leases approximately 24,000 square feet in Longmont,
Colorado as its only office.  The lease on Coral's premises will expire in
February 1999.  Coral believes that such facilities are adequate for its current
needs and that suitable additional space will be available in the future as
needed on commercially reasonable terms.

LEGAL PROCEEDINGS

     The Interference has been declared by the United States Patent and
Trademark office between an issued patent and a patent application of Coral and
a patent application by another company.  Coral's patent and patent application
involve certain technology that is an essential part of its current FraudBuster
product.  Coral is currently in negotiations with the other company regarding
the Interference; however, Coral is currently unable to determine whether it
will be able to settle the Interference on terms satisfactory to Coral, the
ultimate outcome, or the range of possible loss in this matter.  The outcome of
this uncertainty could have a material adverse effect on Coral's business,
operating results, financial condition and cash flow.

     From time to time, Coral has been involved in litigation relating to claims
arising out of its operations in the ordinary course of business.  As of the
date of this Proxy Statement/Prospectus, Coral is not a party to any legal
proceedings other than the interference.

                               LIGHTBRIDGE, INC.
                  UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                  BALANCE SHEET AND STATEMENTS OF OPERATIONS

OVERVIEW

     On September 9, 1997, Lightbridge and Coral entered into the Reorganization
Agreement, pursuant to which Lightbridge proposes to acquire all of the
outstanding shares of Coral Capital Stock.  Under the Reorganization Agreement,
the acquisition would be effected by a merger of Acquisition Corp., a wholly
owned subsidiary of Lightbridge, with and into Coral, with the Surviving
Corporation becoming a wholly owned subsidiary of Lightbridge.  Coral provides
client-server software products for the wireless telecommunications industry to
enable carriers to reduce fraud and customer turnover, or "churn," and increase
operating efficiencies.
    
     Pursuant to the Merger, each of the outstanding shares of Coral Capital
Stock, other than any duly qualified dissenting share, would convert into a
fraction of a share of Lightbridge Common determined as set forth in the
Reorganization Agreement, which determination would be based on the Calculation
Price and subject to the Adjustment Amount. If the Calculation Price is between
$10.8375 and $14.6625, Lightbridge would issue (and reserve for issuance upon
exercise of outstanding Coral options and warrants) an aggregate of 1,286,863
shares of Lightbridge Common, subject to decrease for the Adjustment Amount. If
the Calculation Price is less than $10.8375 or greater than $14.6625, the number
of shares of Lightbridge Common issued (and reserved for issuance) would equal
the quotient of $13,946,375 or $18,868,625, respectively, divided by the
Calculation Price, in each case subject to decrease for the Adjustment 
Amount.     

     In addition, as a result of the Merger, each Option and Warrant outstanding
at the Effective Time, whether vested or unvested, would entitle its holder,
upon exercise (if and when vested) following the Effective Time, to receive that
number of whole shares of Lightbridge Common equal to the product of the number
of shares of Coral Common that were issuable upon exercise of such Option or
Warrant immediately prior to the Effective Time (without regard to vesting)
multiplied by the conversion rate for a single share of Coral Common, rounded
down to the nearest whole number of shares of Lightbridge Common.  In addition,
following the Effective Time, the per share exercise price for the Lightbridge
Common issuable upon exercise of each Option and Warrant would be equal to the
per share exercise price thereof immediately prior to the Effective Time divided
by the conversion rate for a single share of Coral Common.

     The acquisition of Coral by Lightbridge would include approximately $16
million of in-process research and development technology that would be written-
off by Lightbridge in the quarter ending December 31, 1997.

     The Unaudited Pro Forma Condensed Consolidated Financial Statements of
Lightbridge consist of an Unaudited Pro Forma Condensed Consolidated Balance
Sheet as of June 30, 1997 and Unaudited Pro Forma Condensed Consolidated
Statements of Operations for the year ended December 31, 1996 and the six months
ended June 30, 1997.  The Unaudited Pro Forma Condensed Consolidated Financial
Statements and related pro forma adjustments thereto should be read in
conjunction with the Consolidated Financial Statements of Lightbridge and Notes
thereto, as well as the Financial Statements of Coral and Notes thereto,
appearing elsewhere in this Proxy Statement/Prospectus.

BASIS OF ACCOMPANYING UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL
STATEMENTS

     The results of Coral's operations would be included in Lightbridge's
operating results after the Closing, which is expected to occur in the quarter
ending December 31, 1997.  The Unaudited Pro Forma Condensed Consolidated
Balance Sheet assumes that Lightbridge's acquisition of Coral occurred on June
30, 1997. The Unaudited Pro Forma Condensed Consolidated Statements of
Operations combine the historical results of operations for Lightbridge and
Coral for the year ended December 31, 1996 and the six months ended June 30,
1997 and assume that the acquisition occurred on January 1, 1996.

Consolidated Financial Statements do not reflect any cost savings and synergies
that might be achieved from the Merger.

     The Unaudited Pro Forma Condensed Consolidated Balance Sheet includes the
effect of the write-off of certain in-process research and development
technology of $16,040,901. However, the Unaudited Pro Forma Condensed
Consolidated Statements of Operations do not consider the effect of this write-
off or other non-recurring charges, expected by Lightbridge management to
approximate $750,000, that may result from the integration of Coral into
Lightbridge. Lightbridge expects to incur these charges during the quarters
ending December 31, 1997 and March 31, 1998.
    
     On October 6, 1997, the last reported sale price per share of Lightbridge
Common on the Nasdaq National Market was $15.875. The Unaudited Pro Forma
Condensed Consolidated Financial Statements assume that the Calculation Price
will exceed $14.6625 and that therefore the market value, based on the
Calculation Price, of the shares of Lightbridge Common issued (or reserved for
issuance) in connection with the Merger will equal $18,868,625, subject to
decrease for the Adjustment Amount. For purposes of the Unaudited Pro Forma
Condensed Consolidated Financial Statements, Lightbridge management has assumed
that the Adjustment Amount will be $400,000, consisting principally of legal,
accounting and other expenses expected to be incurred by Coral and paid by
Lightbridge in connection with the Merger. THE ACTUAL PURCHASE PRICE MAY DIFFER
MATERIALLY FROM THE PRELIMINARY ESTIMATES REFLECTED IN THE UNAUDITED PRO FORMA
CONDENSED CONSOLIDATED FINANCIAL STATEMENTS. See "The Merger Proposal-- 
Calculation of Merger Consideration."     

     The Unaudited Pro Forma Condensed Consolidated Balance Sheet includes
Lightbridge's direct transaction costs associated with the Merger. These direct
costs consist principally of investment advisory, legal, accounting and
appraisal fees. The actual allocation of the final purchase price may differ
from the preliminary estimate reflected in the Unaudited Pro Forma Condensed
Consolidated Financial Statements. There can be no assurance that Lightbridge
will not incur additional charges in subsequent quarters to reflect costs
associated with the Merger or that Lightbridge will be able to integrate the
operations of Coral successfully.

     Lightbridge management believes that the assumptions underlying the pro
forma adjustments used to prepare the Unaudited Pro Forma Condensed Consolidated
Financial Statements provide a reasonable basis for presenting the significant
effects of the Merger. The Unaudited Pro Forma Condensed Consolidated Financial
Statements are not necessarily indicative of the results that would have been
reported had such events actually occurred on the date specified, nor are they
indicative of Lightbridge's future results of operations.

PRO FORMA ADJUSTMENTS

     The following is a summary of the pro forma adjustments made in connection
with the preparation of the Unaudited Pro Forma Condensed Consolidated Financial
Statements. Such adjustments are based upon a preliminary purchase price of:

                      COMPARISON OF STOCKHOLDERS' RIGHTS

     Upon consummation of the Merger, the stockholders of Coral, a Delaware
corporation, will become stockholders of Lightbridge, also a Delaware
corporation.  The following description summarizes the rights of holders of
Lightbridge and Coral stock under Delaware Law.

ACTION BY WRITTEN CONSENT

     Under Section 228 of the Delaware Law, unless otherwise provided in a
corporation's certificate of incorporation, any action required or permitted to
be taken at an annual or special meeting of stockholders may be taken without
such a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action to be taken is signed by the holders of
outstanding stock representing the number of shares necessary to take such
action at a meeting at which all shares entitled to vote were present.

     The Lightbridge Charter prohibits stockholder action by written consent.
The Coral Charter does not prohibit stockholder action by written consent.

CLASS VOTES

     The Delaware Law does not require separate class votes of all voting
classes in order to approve charter amendments, mergers or sales of
substantially all assets. Section 242 of the Delaware Law, however, provides
that all classes of stock, even a nonvoting class of stock, shall vote on
charter amendments that increase or decrease the aggregate number of authorized
shares of such class, increase or decrease the par value of such class, or
adversely affect the rights of holders of shares of such class.

     The Lightbridge Charter does not provide for additional class voting. The
Coral Charter provides that the holders of the Coral Series B, voting as a
separate class, shall be entitled to elect two directors, the holders of the
Coral Series A and Coral Series C, each voting as a separate class, shall be
entitled to elect one director each and the holders of the Coral Common, voting
as a separate class, shall be entitled to elect three directors. The Coral
Charter also provides that the Coral Series A, Coral Series B and Coral Series C
shall vote together as a separate class in order to approve certain actions by
Coral. In addition, the Coral Charter provides that the holders of Coral Series
A, Coral Series B and Coral Series C each shall vote as a separate class with
respect to the authorization or issuance of any equity security senior to, or on
parity with the rights and preferences of, each of the classes of preferred
stock. The Coral Charter also provides that the Coral Series A shall vote as a
separate class with respect to any alteration or change in the rights and
preferences of the Coral Series A.

STOCKHOLDER VOTING

     Section 251 of the Delaware Law requires a majority vote of the shares of
stock of each constituent corporation outstanding and entitled to vote in order
to effectuate a merger between two Delaware corporations.

     The Lightbridge Charter does not require additional votes in order to
effectuate a merger between two Delaware corporations.  The Coral Charter
provides that a merger of Coral with or into any other corporation or entity
must be approved by (i) the holders of a majority of the then-outstanding Coral
Common and (ii) the holders of a majority of the then-outstanding Coral Series
A, Coral Series B and Coral Series C (treating each share of preferred stock as
being equal to the number of Coral Common into which each share of preferred
stock shall then be convertible) voting as a single class.

CERTAIN BUSINESS COMBINATIONS

     Section 203 of the Delaware Law prohibits a corporation from engaging in
any business combination with an interested stockholder (defined as any entity
or person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person associated with, affiliated with or
controlling or controlled by such entity or person) for a period of three years
after the time that the stockholder became an 

                                      100
<PAGE>
 
interested stockholder unless (i) prior to that time, the board of directors of
the corporation approved either the business combination or the transaction
which resulted in the stockholder becoming an interested stockholder, (ii) upon
consummation of the transaction pursuant to which the person became an
interested stockholder, such stockholder owned 85% or more of the outstanding
voting stock at the time the transaction commenced (excluding shares owned by
directors and officers and shares owned by employee stock option plans in which
the participants cannot determine confidentially whether or not the shares would
be tendered in response to a tender or an exchange offer) or (iii) at or
subsequent to the time of the transaction, the business combination is approved
by the corporation's board of directors and by a vote at a meeting (and not by
written consent) of at least two-thirds of the outstanding voting stock not
owned by the interested stockholder.

     Section 203 only applies to Delaware corporations that have a class of
voting stock (i) listed on a national securities exchange, (ii) authorized for
quotation by the Nasdaq Stock Market, Inc. or (iii) held of record by more than
2,000 stockholders. A Delaware corporation may elect in its original certificate
of incorporation, or by amending its certificate of incorporation or by-laws,
that it will not be governed by Section 203. Any such amendment must be approved
by the stockholders and may not be further amended by the board of directors.

     Since Lightbridge is authorized for quotation by the Nasdaq Stock Market,
Inc., Lightbridge is subject to the anti-takeover provisions of Section 203 of
the Delaware Law.  Section 203 currently does not apply to Coral, since it does
not meet any of the criteria set forth above.  Lightbridge has not elected to be
excluded from being governed by Section 203.

DIVIDENDS

     Section 170 of the Delaware Law allows a Delaware corporation to pay
dividends out of surplus or, if there is no surplus, out of its net profits for
the fiscal year in which the dividend is declared and/or the preceding fiscal
year.

APPRAISAL RIGHTS

     Section 262 of the Delaware Law provides for appraisal rights only in the
case of a statutory merger or consolidation of the corporation where the
petitioning stockholder does not consent to the transaction.  In addition, no
appraisal rights are available where the corporation is to be the surviving
corporation and a vote of its stockholders is not required under Section 251(f)
or (g) of the Delaware Law.  In addition, there are no appraisal rights, unless
otherwise provided for in a corporation's certificate of incorporation, for
shares of stock listed on a national securities exchange or held by more than
2,000 holders of record, unless such stockholders would be required to accept
anything other than shares of stock of the surviving corporation, shares of
another corporation so listed or held by such number of holders of record, cash
in lieu of fractional shares of such stock, or any combination thereof.

     Neither the Lightbridge Charter nor the Coral Charter provides for
additional appraisal rights. For more information concerning dissenters' right
under Delaware Law, see "Other Matters Related to the Merger--Appraisal Rights
of Dissenting Stockholders" and ANNEX B hereto.

REDEEMABLE SHARES

     Section 151 of the Delaware Law permits both common and preferred stock to
be made subject to redemption at the option of the corporation, at the option of
the stockholder or upon the happening of a specified event, subject to certain
limitations.

     The Lightbridge Common is not redeemable. None of the Coral Common, Coral
Series A, Coral Series B and Coral Series C are redeemable.

                                      101
<PAGE>
 
AMENDMENT OF BY-LAWS

     Section 109 of the Delaware Law provides that the stockholders entitled to
vote have the power to adopt, amend or repeal by-laws and that a corporation may
confer, in its certificate of incorporation, such powers on the board of
directors.

     Under the Lightbridge Charter, the Lightbridge By-Laws may be altered,
amended or repealed or new by-laws may be adopted by the affirmative vote of a
majority of the directors.  Similarly, the Coral Charter allows the Board of
Directors of Coral to make, amend, supplement or repeal the Coral Bylaws, but
any such bylaws will be subject to the power of the stockholders to change or
repeal them.

LIMITATION ON DIRECTORS' LIABILITY; INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Section 102 of the Delaware Law allows a corporation to include in its
certificate of incorporation a provision that limits or eliminates the personal
liability of directors to the corporation or its shareholders for monetary
damages for breach of fiduciary duty as a director.  Section 102 of the Delaware
Law does not, however, permit a corporation to limit or eliminate the personal
liability of a director for (i) any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
intentional or negligent payment of unlawful dividends or stock purchase or
redemption or (iv) any transaction from which the director derived an improper
personal benefit.

     Both the Lightbridge Charter and the Coral Charter provide for limitations
on the personal liability of any director to the extent permitted by Delaware
Law.

     Section 145 of the Delaware Law provides that a corporation may indemnify
any of its officers and directors party to any action, suit or proceeding by
reason of the fact that he or she was a director, officer, employee or agent of
the corporation by, among other things, a majority vote consisting of directors
who were not parties to such action, suit or proceeding, provided that such
officer or director acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation.

     The Lightbridge Charter and the Lightbridge By-Laws provide for the
indemnification of Lightbridge's officers and directors to the extent permitted
by Delaware Law.  Similarly, the Coral Bylaws provide for the indemnification of
Coral's directors and executive officers to the extent permitted by Delaware
Law.

CLASSIFIED BOARD OF DIRECTORS

     Delaware law permits, but does not require, a classified board of
directors, with staggered terms under which one-half or one-third of the
directors are elected for terms of two or three years, respectively.

     The Lightbridge By-Laws provide that the Board of Directors be divided into
three classes.  One class of directors is elected each year at the annual
meeting of stockholders for a term of office of three years.  Andrew I. Fillat
and D. Quinn Mills serve in the class whose term expires in 1998; Torrence C.
Harder and Pamela D.A. Reeve serve in the class whose term expires in 1999; and
Douglas A. Kingsley serves in the class whose term expires in 2000. Each
director will serve until the expiration of his or her term and thereafter until
a successor is duly elected and qualified. Neither the Coral Charter nor the
Coral Bylaws provide that the Board of Directors be divided into classes.

REMOVAL OF DIRECTORS

     Under Section 141 of the Delaware Law, any director or the entire board of
directors may be removed, with or without cause, by the holders of a majority of
the shares entitled to vote at an election of directors, except (i) unless the
certificate of incorporation otherwise provides, in the case of a corporation
having a classified board, stockholders may effect such removal only for cause
or (ii) in the case of a corporation having cumulative voting, 

                                      102
<PAGE>
 
if less than the entire board is to be removed, no director may be removed
without cause if the votes cast against his removal would be sufficient to elect
him if then cumulatively voted at an election of the entire board of directors.

     The Lightbridge By-Laws provide that directors may be removed only for
cause by the affirmative vote of the holders of at least two-thirds of the
capital stock issued and outstanding and entitled to vote at an election of
directors. Coral does not have a classified board or cumulative voting.

NEWLY CREATED DIRECTORSHIPS AND VACANCIES

     Section 223 of the Delaware Law provides that vacancies and newly created
directorships may be filled by a majority of the directors then in office, even
if the number of directors then in office is less than a quorum, or by a sole
remaining director unless (i) otherwise provided in a corporation's certificate
of incorporation or by-laws or (ii) the certificate of incorporation directs
that a particular class is to elect such director, in which case any other
directors elected by such class, or a sole remaining director, shall fill such
vacancy.  In addition, if, at the time of filling any vacancy or newly created
directorship, the directors then in office constitute less than a majority of
the whole board, the Delaware Court of Chancery may, upon application of
stockholders holding at least ten percent of the shares outstanding at the time
and entitled to vote for such directors, summarily order an election to be held
to fill any such vacancies or newly created directorships, or to replace the
directors chosen by the directors then in office.  Such elections are to be
conducted in accordance with the procedures provided by the Delaware Law.
Unless otherwise provided in the certificate of incorporation or by-laws, when
one or more directors resign from the board, effective at a future date, a
majority of directors then in office, including those who have so resigned, may
vote to fill the vacancy.

     The Lightbridge By-laws provide that vacancies, including those resulting
from an enlargement of the board, shall be filled by the vote of a majority of
the directors then in office, although less than a quorum, or by the sole
remaining director.  The Coral Bylaws provide that, unless otherwise provided in
the Coral Charter, any vacancies and newly created directorships resulting from
any increase in the number of directors shall be filled by a majority of the
directors then in office, even if less than a quorum, unless the Board of
Directors determines that such vacancy or newly created directorship shall be
filled by the stockholders.  The Coral Charter provides that if there are more
than seven directors, the holders of the Coral Series C shall have certain
rights with respect to the election of any additional director.

SPECIAL MEETINGS

     Under Section 211 of the Delaware Law, special meetings of stockholders may
be called by the board of directors and by such other person or persons
authorized to do so by the corporation's certificate of incorporation or by-
laws.

     Under the Lightbridge By-Laws, a special meeting of stockholders may be
called by the president and shall be called by the president or secretary at the
request in writing of a majority of the Board of Directors. Under the Coral
Bylaws, a special meeting of stockholders may be called by (i) the Chairman of
the Board of Directors, (ii) the chief executive officer, (iii) the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors or (iv) by the holders of shares entitled to cast not less
than ten percent of the votes at such meeting.

INSPECTION RIGHTS

     Section 220 of the Delaware Law provides that any stockholder, upon written
demand stating the purpose of the inspection, shall have the right to inspect
for any proper purpose the corporation's stock ledger, a list of its
stockholders, and its other books and records.

                                      103

ELECTION

     In accordance with the Lightbridge By-laws, the Board of Directors will
consist of not less than two nor more than nine directors and the number of
directors shall be determined by resolution of the Board of Directors and may be
increased or decreased at any time or from time to time by the directors by a
vote of a majority of the directors then in office, except that any decrease by
vote of the directors shall only be made to eliminate vacancies existing by
reason of the death, resignation or removal of one or more directors. The Board
of Directors of Lightbridge is divided into three classes. One class of
directors is elected each year at the annual meeting of stockholders for a term
of three years. Each director serves until the expiration of his or her term and
thereafter until a successor is duly elected and qualified. There are currently
five members on the Board of Directors.

     In accordance with the Coral Charter, the Board of Directors is currently
fixed at seven members.  In addition, the holders of Coral Series B, voting as a
separate class, have the right to elect two directors, the holders of Coral
Series A and Coral Series C, each voting as a separate class, have the right to
elect one director each, and the holders of the Coral Common, voting as a
separate class, have the right to elect three directors.  Directors of Coral are
elected at each annual meeting, serve a term of one year and hold office until a
successor is elected and qualified.

     Upon consummation of the Merger, holders of Coral Capital Stock would
become holders of Lightbridge Common. Thereafter, holders of Coral Series A,
Coral Series B and Coral Series C would no longer be entitled to certain rights
and privileges provided for in the Coral Charter, including dividend and
liquidation preferences, conversion rights and certain other protective rights.
Holders of Coral Series A, Coral Series B and Coral Series C also would lose the
right to vote as separate classes concerning certain corporate transactions. In
addition, each holder of Coral Capital Stock would have a percentage ownership
of Lightbridge Common that is substantially less than the holder's current
percentage ownership of Coral Capital Stock. Accordingly, holders of Coral
Capital Stock would have a significantly smaller voting influence over the
affairs of Lightbridge than they currently possess over the affairs of Coral.

     Appraisal rights are available to stockholders of Coral with respect to the
Merger.  See "The Merger Proposal--Appraisal Rights."

                                 LEGAL MATTERS
    
     The legality of the Lightbridge Common to be issued in connection with the
Merger and certain federal tax matters related to the Merger are being passed
upon for Lightbridge by Foley, Hoag and Eliot LLP, Boston, Massachusetts.
Certain federal tax consequences of the Merger are being passed upon for holders
of Coral Capital Stock by Cooley Godward LLP, Boulder, Colorado.

                          INDEPENDENT AUDITORS' REPORT


To the Board of Directors
Lightbridge, Inc.

     We have audited the accompanying consolidated balance sheets of
Lightbridge, Inc. and subsidiary as of December 31, 1995 and 1996, and the
related consolidated statements of operations, stockholders' equity 
(deficiency), and cash flows for the years ended September 30, 1994 and 1995,
the three months ended December 31, 1995, and the year ended December 31, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these 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, such consolidated financial statements present fairly, in
all material respects, the financial position of the Companies at December 31,
1995 and 1996, and the results of their operations and their cash flows for the
years ended September 30, 1994 and 1995, the three months ended December 31,
1995, and the year ended December 31, 1996 in conformity with generally accepted
accounting principles.

                       LIGHTBRIDGE, INC. AND SUBSIDIARY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. BUSINESS AND TECHNOLOGY ACQUISITIONS

     Business--Lightbridge, Inc. (formerly Credit Technologies, Inc.) (the
"Company") was incorporated in June 1989 under the laws of the state of
Delaware. Effective November 1, 1994, the Company changed its name and
reincorporated as Lightbridge, Inc. During 1995, the Board of Directors passed a
resolution to change the Company's fiscal year end to December 31. The Company
develops and markets customer acquisition solutions for the wireless
telecommunications industry. In September 1996, the Company organized a wholly
owned subsidiary, Lightbridge Security Corporation, as a Massachusetts
securities corporation for tax purposes, to buy, hold and sell securities.

     In September 1996, the Company completed an initial public offering (the
"IPO") whereby 3,021,868 shares of its Common Stock ($.01 par value) were sold
by the Company, 778,132 shares by selling shareholders and 570,000 additional
shares sold by selling shareholders pursuant to the exercise of the
over-allotment option by the underwriters at $10.00 per share. The net proceeds
of the IPO, after deducting underwriters' commissions and fees and offering
costs, were approximately $27.1 million. These proceeds were used to repay
certain debt obligations of the Company, to repurchase certain shares of the
common stock of the Company and to fund working capital and other general
corporate purposes.

     Technology Acquisitions--During the year ended September 30, 1995, the
Company completed the following technology acquisitions:

     o    In November 1994, the Company purchased the technology for a pen-based
          software product for $400,000.

     o    In February 1995, the Company purchased the software technology for a
          multimedia kiosk for $45,000. The Company is also obligated to make
          royalty payments to the former owners based on future sales of the
          product.

     The costs associated with these acquisitions were recorded as capitalized
software costs, since such products had reached technological feasibility at the
date of acquisition.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation and Principles of Consolidation--These consolidated
financial statements include the accounts of the Company and its subsidiary. All
intercompany accounts and transactions have been eliminated in consolidation.

     Cash and Cash Equivalents--Cash and cash equivalents include short-term,
highly liquid instruments, which consist primarily of money market accounts,
purchased with remaining maturities of three months or less.

     Property and Equipment--Property and equipment is recorded at cost.
Depreciation is provided using the straight-line method over the estimated
useful lives of the respective assets ranging from three to seven years.
Leasehold improvements are amortized over the term of the lease or the lives of
the assets, whichever is shorter.

     Revenue Recognition and Concentration of Credit Risk--Revenues from
processing of qualification and activation transactions for wireless
telecommunications carriers are recognized in the period when services are
performed. Revenues derived from software implementation projects are recognized
throughout the performance period of the contracts. Revenues arising from the
prepayment of fees or from licensing agreements where the Company has continuing
vendor obligations are deferred.

     Substantially all of the Company's customers are providers of wireless
telephone service and are generally granted credit without collateral. The
Company's revenues vary throughout the year with the period of highest revenue
generally occurring during the period October 1 through December 31. The
allowance for doubtful accounts at September 30, 1994 and 1995 and at December
31, 1995 and 1996 was $25,000, $9,000, $22,200 and $18,000, respectively. The
Company recorded bad debt expense of $25,000, $0, $13,200 and $0 and had
write-offs, net of recoveries associated with accounts receivable of $0,
$16,000, $0 and $4,200 for the years ended September 30, 1994, 1995, the three
months ended December 31, 1995 and the year ended December 31, 1996.


     Customers exceeding 10% of the Company's revenues during the years ended
September 30, 1994 and 1995, the three months ended December 31, 1995, and the
year ended December 31, 1996 are as follows:

     * For periods in which a customer represented less than 10% of revenues,
such customer's percent of revenue for that period is not presented.



     Income Taxes--The Company has adopted the provisions of Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income
Taxes." SFAS No. 109 requires the recognition of deferred tax assets and
liabilities for the expected future tax consequences of temporary differences
between the financial reporting and tax bases of existing assets and
liabilities. Deferred income tax assets are principally the result of net
operating loss carryforwards and differences in depreciation and amortization
for financial statement purposes and income tax purposes, and are recognized to
the extent realization of such benefits is more likely than not.

     Software Development Costs--Software development costs are capitalized
after establishment of technological feasibility as provided for under SFAS No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed."

     During the year ended September 30, 1995, the Company capitalized
approximately $980,400 of software development costs associated with the
development of two new products, including the costs of purchasing certain
technology (see Note 1). Capitalized software development costs are being
amortized to cost of revenues using the straight-line method over 24 months
which results in the highest levels of amortization. Accumulated amortization
was approximately $218,000 and $625,000 at December 31, 1995 and 1996,
respectively.

     Development Costs--Development costs, which consist of research into and
development of new products and services, are expensed as incurred, except costs
which may be subject to capitalization under the provisions of SFAS No. 86.


     Supplemental Cash Flow Information--The Company entered into the following
noncash transactions:

     In both April and September of 1996, the Company reacquired 200,000 shares
of its common stock from a former director. These repurchases were partially
financed through the issuance of two separate 8% notes payable in the amount of
$226,667 and $260,000. Such notes were repaid during 1996.

     Pro Forma Income (Loss) Per Common Share--Pro forma income (loss) per
common share is based on the weighted average number of common and dilutive
common equivalent shares (common stock options and warrants) outstanding and
assumes that all series of redeemable convertible preferred stock had been
converted to common stock for all pro forma periods presented. Common equivalent
shares are not included in the per share calculations where the effect of their
inclusion would be anti-dilutive, except in accordance with the requirements of
Securities and Exchange Commission Staff Accounting Bulletin No. 83. That
Bulletin requires all common shares issued and options or warrants to purchase
common stock granted by the Company during the twelve-month period prior to the
filing of a proposed initial public offering be included in the calculation as
if they were outstanding for all periods. For purposes of applying the Bulletin,
the Company has used the initial public offering price of $10 per share.


     Historical income (loss) per share, which includes the conversion of the 
redeemable convertible preferred stock on the actual date of conversion, was as
follows:

     Fair Value of Financial Instruments--In the opinion of management, the
estimated fair value of the Company's financial instruments, which include cash
equivalents, accounts receivable and long-term debt, approximates their carrying
value.

     Impairment of Long-Lived Assets--In March 1995, the Financial
Accounting Standards Board ("FASB") issued SFAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of." SFAS No. 121 addresses the accounting for the impairment of
long-lived assets, certain identifiable intangibles and goodwill when
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. The adoption of SFAS No. 121 in 1996 did not
have a material impact on the Company's results of operations, financial
position or cash flows.

     Stock-Based Compensation--In November 1995, the FASB issued SFAS No.
123, "Accounting for Stock-Based Compensation." SFAS No. 123 addresses the
financial accounting and reporting standards for stock-based compensation
plans and permits an entity to either record the effects of stock-based
employee compensation plans in its financial statements or present pro
forma disclosures in the notes to the financial statements. Compensation
expense associated with awards to non-employees is required to be measured
using a fair value method. In connection with the adoption of SFAS No. 123
during 1996, the Company elected to provide the appropriate disclosures in
the notes to the financial statements for employee compensation plans.
Since the Company does not expect to make significant equity awards to
outsiders in the future, adoption of SFAS No. 123 is not expected to 
impact the Company's future consolidated results of operations, financial 
position or cash flows.

   Recent Accounting Pronouncement--

          Earnings Per Share--In February 1997, the FASB released SFAS No. 128,
     "Earnings Per Share," which will be effective for fiscal 1997. SFAS No. 128
     will require the Company to restate amounts previously reported as earnings
     per share to comply with the requirements of SFAS No. 128; while the 
     Company is in the process of evaluating the impact of SFAS No. 128, it 
     does not expect that adoption will have a dilutive effect on previously 
     reported earnings per share.

          Significant Estimates--The preparation of financial statements in
     conformity with generally accepted accounting principles necessarily
     requires management to make estimates. These estimates include provisions
     for bad debts, certain accrued liabilities, recognition of revenue and
     expenses, and recoverability of deferred tax assets. These estimates could
     change; however, the Company does not expect any changes in the near term
     that would have a significant impact on the financial statements.

          Stock Split--On June 14, 1996, the Board of Directors authorized a two
     for one stock split effective on July 15, 1996. All shares and per share
     information included in the financial statements has been restated to
     reflect this stock split. In addition, during 1996, the number of shares of
     authorized common stock was increased to 60,000,000.

          Reclassifications--Certain reclassifications have been made to the
     1994 and 1995 financial statements to conform with the 1996 presentation.

     Line of Credit--Prior to 1996, the Company had a line of credit agreement
with a bank (the "Bank Agreement") which permitted the Company to borrow up to
$2,000,000 ($1,000,000 during 1994) subject to certain borrowing formulae
established by the bank. Interest based on prime plus .5% was charged on any
outstanding borrowings. In December 1995, the Bank Agreement was amended to
reduce the amount of permitted borrowings to $1,500,000 and the outstanding
borrowings under the Bank Agreement, $1,500,000, were converted to a demand note
due in March 1996 (the "Demand Note Agreement"). The weighted average annual
interest rate for outstanding borrowings during the years ended September 30, 
1994 and 1995 and the three months ended December 31, 1995 approximated 9.75%,
9.9% and 9.5%, respectively.

     During 1996, the Company converted the existing demand note agreement (the
"Amended Bank Agreement") to a line of credit which increased the maximum
borrowing limit to $4,000,000, subject to a borrowing base formula, decreased
the interest rate to prime plus .25% and extended the agreement to June 1997.
The weighted average annual interest rate on outstanding borrowings during 1996
was 9.4%. The Amended Bank Agreement contains certain restrictions which, among
others, limits the Company's ability to pay cash dividends and requires the
Company to achieve defined levels of quarterly earnings and tangible net worth,
as well as meeting defined ratios of senior liabilities to net worth and quick
assets. Borrowings under the Amended Bank Agreement are collateralized by the
Company's accounts receivable, equipment and intangible assets.

     The Amended Credit Agreement was further amended on March 5, 1997 to
provide for the issuance of letters of credit. Outstanding letters of credit
reduce the amount the Company may borrow under the Amended Credit Agreement and
are limited to $1,250,000 in the aggregate.

     Line of Credit-Equipment--The Company has a $2,000,000 line of credit
available for equipment purchases (the "Equipment Line"). Borrowings under the
Equipment Line are payable in 30 monthly installments of principal and interest
commencing January, 1997 and ending June, 1999. Interest on the Equipment Line
is payable at prime plus .75%. The weighted average annual interest rate for
outstanding borrowings under the Equipment Line during the year ended December
31, 1996 approximated 8.78%.

     16% Subordinated Notes--In August 1995, the Company issued $1,151,000 of
16% subordinated notes to certain holders of the Company's redeemable preferred
stock, with immediately exercisable warrants for the purchase of 287,750 shares
of the Company's common stock. Interest on the notes was accrued monthly, and
principal and accrued interest were payable on January 31, 1996. Such repayment
obligations were extended by the note holders until the Company completed the
placement of its Series D Preferred Stock on April 4, 1996 (See Note 6). The
warrants are exercisable through June 30, 2001 at a price of $2 per share and
have been appraised and recorded at an aggregate market value of $143,875. The
related discount on the subordinated note ($143,875 at time of issuance) has
been accreted over the originally scheduled term of the notes. Interest expense
for the year ended September 30, 1995, the three months ended December 31, 1995
and the year ended December 31, 1996 includes approximately $38,900, $78,500 and
$26,475 of accretion, respectively. The Company repaid principal and interest
related to these notes in full upon the sale of its Series D Preferred Stock.
The amount outstanding related to these notes was classified as long term at
December 31, 1995, reflecting the Company's refinancing of this obligation
through the issuance of Series D Preferred Stock.

     8% Subordinated Notes--In August 1994, the Company issued $2,100,000 of
subordinated notes to certain holders of the Company's common and mandatory
redeemable preferred stock, with immediately exercisable warrants for the
purchase of 525,000 shares of the Company's common stock. The warrants are
exercisable through June 30, 2001 at a price of $2 per share and have been
appraised and recorded at an aggregate market value of $262,500. The related
discount on the subordinated notes ($262,500 at time of issuance) is being
accreted over the term of the notes. Interest expense for the years ended
September 30, 1994 and 1995, the three months ended December 31, 1995 and the
year ended December 31, 1996 includes accretion related to these notes of
approximately $4,200, $37,500, $9,375 and $37,500, respectively. Interest on the
notes is payable quarterly at an annual rate of 8%. Principal is payable in
quarterly installments of $131,250 beginning on September 30, 1997 through
maturity (2001). The notes are redeemable at the Company's option at par plus
declining premiums at various dates.

     Rent expense for operating leases was approximately $454,000, $1,503,000,
$405,000, and $1,797,000 for the years ended September 30, 1994 and 1995, for
the three months ended December 31, 1995, and for the year ended December 31,
1996, respectively.

     Litigation--During 1996, the Company and certain affiliates (the
"Entrepreneurial Partnerships") (collectively, the "Plaintiffs") reached an
agreement to settle various lawsuits between the Plaintiffs and a former
director of the Company (see Note 10). In addition to settling all claims and
disputes, the former director agreed, in exchange for payments of $25,500 each,
to grant the Company and the Entrepreneurial Partnerships' various options to
purchase the Company's common stock from the former director (the "Settlement
Shares"). The Company's purchase option permitted the Company to purchase
Settlement Shares in 200,000 share allotments during each of three specified
periods of time through February 1997 at purchase prices of $1.70, $1.95 and
$2.20 per share during the first, second and final share allotments,
respectively. In the event that the Company chose not to immediately pay for the
Settlement Shares, a portion of the purchase price (66.67%) could be financed by
issuing the former director an 8% two-year note. During 1996, the Company
exercised its option to purchase 600,000 settlement shares of which a portion
were temporarily financed during the year and subsequently repaid in October
1996.

     In connection with the exercise of the options by the Entrepreneurial
Partnerships, on March 28, 1996 the Company loaned an aggregate of $113,333 to
the Entrepreneurial Partnerships at an interest rate of 16%. Such amount was
repaid in May 1996. In May 1996, the Company repurchased for cash consideration
an additional 200,000 shares of its common stock from certain Entrepreneurial
Partnerships at a price of $1.70 per share and reimbursed the Entrepreneurial
Partnerships, by means of a distribution, for certain legal fees and expenses
incurred by them in connection with the litigation against the former director
in the amount of $200,000.

     During 1991, the Company issued 630,516 shares of redeemable convertible
preferred stock ("Series A Preferred Stock") for an aggregate purchase price of
$1,000,000, of which 315,258 shares were issued to a third-party investor and
315,258 shares were issued to certain Entrepreneurial Partnerships which are
related parties.

     Also during 1991, the Company issued 620,000 shares of redeemable
convertible preferred stock ("Series B Preferred Stock") for an aggregate
purchase price of $1,085,000.

     In June 1993, the Company issued 200,789 shares of redeemable convertible
preferred stock ("Series C Preferred Stock") for an aggregate purchase price of
$602,367.

     In April 1996, the Company issued 1,000,000 shares of redeemable
convertible preferred stock ("Series D Preferred Stock") for an aggregate
purchase price of $6,000,000.

     Conversion and Liquidation Preferences--Each share of Series A and Series D
Preferred Stock was convertible into two shares of common stock. Each share of
Series B and Series C Preferred Stock was convertible into approximately 2.42
and 2.40 shares of common stock, respectively. The Preferred Stock was
convertible upon a sale of the Company's stock or net assets for an amount in
excess of $7,500,000, with a minimum price per share of $5.25. In the event of a
liquidation, merger, consolidation, or sale of the Company's assets, the holders
of the various classes of Preferred Stock were entitled to receive a liquidation
preference equal to their aggregate purchase price plus accreted and unpaid
dividends outstanding prior to any distributions to holders of common stock of
the Company. Each share of Preferred Stock entitled the holder to the number of
votes per share equivalent to the number of common shares into which each share
of preferred stock was then convertible.

     Dividends--On October 1, 1992, the Series A and Series B Preferred Stock
began accruing dividends at the rate of 8% per annum. The Series C Preferred
Stock began accruing dividends at the rate of 8% per annum beginning on October
1, 1993. Prior to the issuance of the Series D Preferred Stock, the Series A,
Series B and Series C Preferred Stock dividends were payable in cash for fiscal
years in which the Company has net income in excess of $500,000 and accruable in
all other years. Accrued dividends outstanding for any year were payable in cash
in subsequent years to the extent net income exceeded the required minimum of
$500,000 by an additional $500,000. No dividends were paid in the years ended
September 30, 1994 and 1995 or the three months ended December 31, 1995. In
connection with the issuance of the Series D Preferred Stock, the Series A,
Series B and 

                                       F-13
<PAGE>
 
Series C Preferred Stock dividends became payable in cash or by subordinated
promissory note for fiscal years in which the Company's net income was
$1,000,000 or more, to the extent of the lesser of 20% of net income in excess
of $1,000,000 or all dividends then payable. For financial reporting purposes,
the dividends were accreted ratably over the period the Preferred Stock was
expected to be outstanding to the extent not required to be paid. Dividends
payable for all periods presented consisted of $80,076 and $86,800 required to
be paid on the Series A and Series B Preferred Stock, respectively, as a result
of the Company's 1994 net income. The Company expects to pay those dividends in
1997.


     Redemption--Prior to the issuance of the Series D Preferred Stock, the
Series A and Series B Preferred Stock had a mandatory redemption date of
December 31, 1997 and the Series C Preferred Stock had a mandatory redemption
date of December 31, 1999. Since the issuance of the Series D Preferred Stock,
holders of two-thirds of all shares of Series A, B and C Preferred Stock could
have, commencing on April 1, 2000 and on the same date in each following year,
required the Company to redeem 1/3 of their shares. The redemption amount
equaled the higher of the fair market value of the preferred stock as of the
fiscal year end closest to the redemption date or an amount equal to the
aggregate purchase price plus accrued dividends outstanding.


7. COMMON STOCK OPTION PLANS AND WARRANTS

     1990 Incentive and Nonqualified Stock Option Plan--Under the Company's 1990
Incentive and Nonqualified Stock Option Plan, the Company could grant either
incentive or nonqualified stock options to officers, directors, employees or
consultants for the purchase of up to 2,400,000 shares of common stock. Options
were granted with an exercise price equal to the common stock's market value at
the date of grant, as determined by the Board of Directors, and would expire ten
years later. No further grants will be made under the 1990 Incentive and
Nonqualified Stock Option Plan.

     1996 Employee Stock Plans--On June 14, 1996, the Board of Directors
authorized and the stockholders approved the adoption of the 1996 Incentive and
Nonqualified Stock Option Plan and the 1996 Stock Purchase Plan for the issuance
of options or sale of shares to employees. Both plans became effective
immediately after the closing of the Company's IPO:

     -    1996 Incentive and Nonqualified Stock Option Plan--The 1996 Incentive
          and Nonqualified Stock Option Plan provides for the issuance of up to
          1,000,000 options to purchase shares of common stock. Options may be
          either qualified incentive stock options or nonqualified stock options
          at the discretion of the Board of Directors. Exercise prices will be
          either fair market value on the date of grant, in the case of
          incentive stock options, or set by the Board of Directors at the date
          of grant, in the case of nonqualified options.

     -    1996 Employee Stock Purchase Plan--The 1996 Stock Purchase Plan 
          provides for the sale of up to 100,000 shares of common stock to 
          employees. Employees will be allowed to purchase shares at a discount
          from the lower of fair value at the beginning or end of the purchase 
          periods through payroll deductions.

</TABLE> 

   The fair value of options on their grant date was measured using the
Black/Scholes option pricing model. Key assumptions used to apply this pricing
model are as follows:

<TABLE> 
<CAPTION> 

                                                                           THREE MONTHS          YEAR ENDED

   the stock price on the date of grant.........................               --                    --

</TABLE> 

     It should be noted that the option pricing model used was designed to value
readily tradable stock options with relatively short lives. The options granted
to employees are not tradable and have contractual lives of up to ten years.
However, management believes that the assumptions used to value the options and
the model applied yield a reasonable estimate of the fair value of the grants
made under the circumstances.

     The pro forma effect on net income and earnings per share for the three
months ended December 31, 1995 and the year ended December 31, 1996 is not
representative of the pro forma effect in future years because it does not take
into consideration pro forma compensation expense related to grants made prior
to the three months ended December 31, 1995.

     Common Stock Warrants--The Company has issued warrants to purchase
1,270,038 shares of the Company's common stock at exercise prices ranging from
$0.793 to $2.00 per share. Warrants issued prior to August 1994 were assigned
nominal value based upon management's estimate of their fair market value.
Warrants issued in connection with the Company's issuance of subordinated notes
(see Note 4) have been ascribed an aggregate value of $406,375. During 1996,
warrant holders with warrants to purchase 457,288 shares of common stock
exercised such warrants in conjunction with the IPO. The warrant holder
surrendered a portion of the warrants, valued at the IPO price of the common
stock, in lieu of payment of the cash exercise price. In addition, a director
exercised a warrant for 3,234 shares in conjunction with the IPO which was
valued at the IPO price of common stock. In June 1996, a warrant holder
exercised a warrant for 62,500 shares which had an exercise price of $2.00 per
share. In conjunction with the IPO, the Company issued warrants to a former
director to purchase 100,000 shares of common stock at the IPO price. The
compensation expense recognized for this warrant grant was $230,000 and was
determined by using the Black/Scholes pricing model. At December 31, 1996,
warrants to purchase shares of common stock aggregated 847,016 (747,016 shares
at an exercise price of $2.00 and 100,000 shares at an exercise price of
$10.00.) Such shares are subject to certain antidilutive adjustments.

     Reserved Shares--The Company has reserved 3,577,016 shares of common stock
for issuance for the stock purchase plan and the exercise of stock options and
warrants.

          8. INCOME TAXES

     In October 1993, the Company implemented the provisions of SFAS No. 109.
The cumulative effect of this change did not have a material effect on the
Company's results of operations, financial position or cash flows as a result of
the valuation allowance established at the time of adoption.


     The income tax (benefit) provision for the years ended September 30, 1994
and 1995, the three months ended December 31, 1995, and for the year ended
December 31, 1996 consisted of the following:

     The net change in the valuation allowance for the years ended September 30,
1994 and 1995, the three month period ended December 31, 1995 and the year ended
December 31, 1996 was an increase (decrease) of $(409,258), $956,390, $(55,211)
and $(713,913), respectively. At December 31, 1996, the Company had no remaining
net operating loss carryforwards for federal income tax purposes. A valuation
allowance was established against the deferred tax assets as their realization
is not assured.


     The following is a reconciliation of income taxes at the federal statutory
rate to the Company's effective tax rate:

9. EMPLOYEE PROFIT SHARING PLAN

     The Company has a 401(k) Employee Profit Sharing Plan (the "Plan"). Under
the Plan, the Company, at its discretion, may make contributions to match
employee contributions. All employees of the Company are eligible to
participate, subject to employment eligibility requirements. Vesting of employer
contributions occurs ratably over a five-year period. Employer contributions
amounted to approximately $27,500, $43,000, $20,000 and $91,000 for the years
ended September 30, 1994 and 1995, the three months ended December 31, 1995, and
the year ended December 31, 1996, respectively.

10. RELATED-PARTY TRANSACTIONS

     Under an agreement dated February 28, 1990, the Company granted an
exclusive license to RentGrow, Inc. ("RentGrow"), a company having certain
common investors with the Company, to use the Company's Credit Decision System
in the rental real estate market. Under the terms of the agreement, the Company
was to receive $250,000, comprised of five installments in varying amounts
through August 1996. The final payment was not made in August 1996. In 1997, the
Company received from RentGrow a three year 11.25% promissory note in the
principal amount of $75,584 representing the final payment and other amounts
owed to the Company at December 31, 1996. In addition, this agreement provides
for the Company to maintain the licensed software, at RentGrow's option, at an
annual amount equal to 15% of the license amount, which the Company believes
exceeds the cost of providing such maintenance.

     The Company has received advances from various Entrepreneurial Partnerships
and their general partners and has issued preferred stock to various
Entrepreneurial Partnerships. The Company leased computer equipment from various
Entrepreneurial Partnerships. The general partners of these partnerships are
also stockholders of the Company. In 1992, the Company sold and leased back
equipment from an Entrepreneurial Partnership resulting in a gain of $12,518,
which was deferred and amortized over the capital lease term. The amount
deferred was $2,781, $0, $0 and $0 as of September 30, 1994 and 1995 and
December 31, 1995 and 1996, respectively.

     On August 26, 1996, the Company entered into an agreement with the former
director pursuant to which the Company paid $75,000 to the former director and
granted the former director the warrant (described in Note 7) to purchase
100,000 shares of the Company's Common Stock at the IPO price in exchange for
the execution of certain agreements related to the IPO.

                       LIGHTBRIDGE, INC. AND SUBSIDIARY

        NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.  Basis of Presentation:

     The consolidated financial statements included herein have been prepared by
Lightbridge, Inc. (the "Company"), without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Although certain
information and footnote disclosures normally included in annual financial
statements have been omitted, the Company believes that the disclosures are
adequate to make the information presented not misleading and reflect all
adjustments (consisting only of normal recurring adjustments) which are
necessary for a fair presentation of results of operations for such periods.
Results of interim periods may not be indicative of results for the full year.
It is suggested that these financial statements be read in conjunction with the
consolidated financial statements and notes thereto included at pages F-2
through F-18 herein.

2.  Significant Accounting Policies:

Net Income Per Common Share

     Net income per common and per common equivalent share are computed using
the weighted average number of common and dilutive common equivalent shares
outstanding during the period, using the provisions of Accounting Principles
Board Opinion No. 15, "Earnings per Share." Dilutive common equivalent shares
represent shares issuable upon exercise of stock options and warrants,
calculated using the treasury stock method. Primary and fully diluted earnings 
per share were the same for the three and six month periods ended June 30, 1997.

     Pro forma income per common share for the three month and six month periods
ended June 30, 1996 is based on the weighted average number of common and
dilutive common equivalent shares (common stock options and warrants)
outstanding and assumes that all series of redeemable convertible preferred
stock had been converted to common stock as of January 1, 1996. Common
equivalent shares are not included in the per share calculations where the
effect of their inclusion would be anti-dilutive, except in accordance with the
requirements of Securities and Exchange Commission Staff Accounting Bulletin No.
83. That Bulletin requires all common shares issued and options or warrants to
purchase common stock granted by the Company during the twelve-month period
prior to the filing of a proposed initial public offering be included in the
calculation as if they were outstanding for all periods. For purposes of
applying the Bulletin, the Company has used the initial public offering price of
$10 per share from the Company's offering in October 1996.

     In February 1997, the Financial Accounting Standards Board released
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share," which the Company will adopt in the fourth quarter of 1997. Had SFAS No.
128 been effective for the six months ended June 30, 1997 and 1996, reported
earnings per share would have been as follows:

Income Taxes

     In October 1993, the Company adopted SFAS No. 109. "Accounting for Income
Taxes." In connection with the adoption, the Company recorded a deferred tax
asset relating to the tax benefit of operating losses, and differences between
the carrying amounts of assets and liabilities for financial reporting purposes
and the amounts used for income tax purposes. At that time the Company provided
a full valuation allowance equal to the entire deferred tax asset as the

                                     F-22



<PAGE>
 
Company believed it was more likely than not that the deferred tax asset would
not be realized.


     During the first quarter of 1997, the Company determined that the valuation
allowance was no longer necessary for the existing deferred tax assets and
deferred tax assets arising during the quarter, and recorded an income tax
benefit of approximately $644,000.

Reclassifications

     Certain reclassifications have been made to the 1996 financial statements
to conform with the 1997 presentation.

                        Report of Independent Accountants


To the Board of Directors and
Stockholders of Coral Systems, Inc.

In our opinion, the accompanying balance sheet and the related statements of
operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of Coral
Systems, Inc. at December 31, 1996 and 1995, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1996, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 12 to the
financial statements, the Company has suffered recurring losses from operations
and has an accumulated deficit that raise substantial doubt about its ability to
continue as a going concern. Management's plans in regard to these matters are
also described in Note 12. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

1.  Nature of Business and Summary of Significant Accounting Policies

            Coral Systems, Inc. (the "Company") was incorporated in August 1991.
The Company develops and provides software solutions for the wireless
telecommunications industry. The solutions enable carriers to reduce fraud and
customer turnover and increase operating efficiencies.

Summary of Significant Accounting Policies

Revenue Recognition

            The Company generates revenue from software licenses; services
(including maintenance, installation and training); development and consulting
contracts; and certain hardware sold in conjunction with software licenses. The
Company's software license agreements typically provide for an initial license
fee and annual maintenance based on a defined number of subscribers, as well as
additional license and maintenance fees for net subscriber additions. The
Company also has entered into license agreements that provide for either a one-
time license fee or a monthly license fee with no additional fees based on
incremental subscriber growth.

            Revenue from initial license fees with end users is recognized when
the product has been delivered and the Company has satisfied all significant
performance obligations, unless terms of the sales arrangement provide for
customer acceptance that is based on non-standard performance or other terms. In
the latter case, revenue is recognized when the customer accepts the product
pursuant to those terms. Revenue for incremental subscriber growth, if any, is
recognized at the date subscriber growth is calculated and the revenue is earned
pursuant to the terms of the relevant software license agreement. Monthly
license fees are recognized as earned on a monthly basis. Maintenance revenue is
recognized ratably over the term of the maintenance agreement. Service revenue
for installation and training is recognized as the services are performed.
Revenue from development and consulting contracts is generally recognized as the
services are performed, using the percentage of completion method. Hardware is
sold only in conjunction with software licenses when required by the customer
and such revenue is deferred until the related license revenue is recognized.

            Sales agreements with distributors typically do not include any
rights of return or provisions for the future adjustment of the selling price.
The Company recognizes revenue from these transactions at the time the products
are shipped to the distributor, unless payment terms are contingent on the
distributor's subsequent resale or other significant matters. In those latter
cases, revenue is not recognized until the contingencies are resolved.

Concentration of Credit Risk

            Accounts receivable are concentrated in the wireless
telecommunications industry, with both domestic and international customers.
During the years ended December 31, 1994, 1995 and 1996, and the six months
ended June 30, 1997, the Company recognized approximately 89%, 77%, 59%, and 80%
(unaudited) of its revenue from four, five, two, and two (unaudited) customers,
respectively.

Notes to Financial Statements (continued)
================================================================================


            Financial instruments which potentially subject the Company to
concentrations of credit risk are primarily accounts receivable and cash
equivalents. The Company performs ongoing credit evaluations of its customers'
financial condition and, generally, requires no collateral from its customers.
The Company has a cash investment policy which restricts investments to ensure
preservation of principal and maintenance of liquidity.

Cash and Cash Equivalents

            The Company considers cash on hand, deposits in banks, and
investment instruments purchased with original maturities of less than three
months to be cash and cash equivalents. Cash equivalents are carried at
amortized cost which approximates fair value.

Property and Equipment

            Property and equipment are recorded at cost. Depreciation is
computed using straight-line and accelerated methods over the estimated useful
lives of the respective assets which range from three to seven years.
Maintenance and repairs are expensed as incurred.

Software Development Costs

            Research and development costs are expensed as incurred. Statement
of Financial Accounting Standards No. 86 (SFAS No. 86) requires the
capitalization of certain software development costs once technological
feasibility is established. The capitalized cost is then amortized on a
straight-line basis over the estimated product life, or on the ratio of current
revenue to total projected product revenue, whichever is greater. To date, the
period between achieving technological feasibility and the general availability
of such software has been short. Consequently, software development costs
qualifying for capitalization have been insignificant and therefore, the Company
has not capitalized any software development costs to date.

Estimates

            The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities as well as the reported amounts of revenue
and expenses. Actual results could differ from these estimates.

Fair Value of Financial Instruments

            The carrying amounts of the Company's financial instruments,
including cash, short-term trade receivables and payables and long-term debt,
approximate their fair values.

Stock Compensation Plans

            The Company applies APB Opinion No. 25, Accounting for Stock Issued
to Employees, in accounting for its stock option and employee stock purchase
plans. The Company has adopted the disclosure provisions of SFAS No. 123,
Accounting for Stock-Based Compensation.

Export Sales

            The Company had export sales to the following countries:

Adoption of New Accounting Standards

            The Company has adopted Statement of Financial Accounting Standards
No. 121 Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of. Adoption of this standard did not have a material
effect on the Company's financial position and results of operations.

Unaudited Interim Financial Data

            The interim financial data as of June 30, 1997, and for the six
months ended June 30, 1996, and June 30, 1997, is unaudited; however, in the
opinion of management of the Company, the interim data includes all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results for the interim periods presented. All data
presented in these notes at such date and for such periods is unaudited.

5. Capital Stock, Options and Warrants

Stock Split

     In October 1996, a one-for-two reverse split of the Company's common stock
was consummated. All common stock share and per share information and all
preferred stock conversion rates presented in these financial statements have
been restated for all periods presented to reflect the reverse stock split.

Preferred Stock

     In March 1996, the Company's certificate of incorporation was amended to
increase the authorized shares of preferred stock from 5,000,000 shares to
15,000,000 shares consisting of: 2,000,000 shares of Series A preferred stock,
2,083,333 shares of Series B preferred stock, 1,850,000 shares of Series C
preferred stock and 9,066,667 shares undesignated as to series.

     Series A and Series C preferred stock are convertible at the option of the
holder into common stock on a two-for-one basis; Series B preferred stock is
convertible on a one-for-one basis. In the event of a qualified public offering,
all preferred shares will automatically convert to common stock. Additionally,
all preferred shares have certain voting rights on an as-converted basis and a
liquidation preference equal to the original purchase price plus a pro rata
portion of remaining liquidation proceeds in excess of the liquidation 
preference proceeds paid to common stockholders.

Employee Stock Purchase Plan

     In August 1996, the Company's Board of Directors approved the Employee
Stock Purchase Plan (the "Purchase Plan") with 450,000 shares of common stock
reserved for issuance thereunder. The Purchase Plan is intended to qualify as an
employee stock purchase plan within the meaning of Section 423 of the Internal
Revenue Code. Under the Purchase Plan, the Board of Directors may authorize
participation by eligible employees, including officers, in periodic offerings
following the adoption of the Purchase Plan. Employees, other than part-time or
seasonal employees and 5% stockholders, are eligible to participate in the
currently authorized offerings if they are employed by the Company or an
affiliate of the Company incorporated in the U.S. Employees may elect to have up
to 15% of their earnings withheld and applied to the purchase of common stock at
a price equal to 85% of the lower of the fair market value of the common stock
on the commencement date of each offering period or the relevant purchase date.
The Board has currently authorized an offering commencing on the effective date
of an initial public offering of the Company's common stock. No shares of common
stock have been issued to participants in the Purchase Plan to date.

            The Company applies APB Opinion 25 in accounting for its stock
compensation plans through December 31, 1996, and no compensation expense has
been recognized in the financial statements as all grants were made with
exercise prices not less than fair value. Had compensation expense for the
Company's stock option plan been determined based on the minimum values at the
grant dates for awards under the plan for grants made in 1995 and 1996
consistent with the method of accounting prescribed by FASB Statement 123, the
Company's net loss and loss per share would have been increased to the pro forma

following weighted-average assumptions used for grants in the year ended
December 31, 1995 and 1996: dividend yield of zero; expected volatility of zero;
risk-free interest rates ranging from 5.62% to 7.13%; and an expected term of
six years. The risk-free rate used in the calculation is the yield on the grant
date of a U.S. Treasury Strip with a maturity equal to the expected term of the
option.

6.  Income Taxes

            The Company's net deferred tax assets consist of the following (in 
thousands):

</TABLE> 

            Based upon the Company's accumulated deficit and history of
recurring net losses, the ultimate realization of the deferred tax asset does
not appear to be more likely than not. Accordingly, a valuation allowance has
been provided against all potential future tax benefits.

</TABLE> 

     At December 31, 1996, the Company has net operating loss carryforwards
aggregating approximately $8,109,000 which expire between 2006 and 2010. The
Internal Revenue Code places certain limitations on the annual amount of net
operating loss carryforwards which can be utilized if certain changes in the
Company's ownership occur. Such defined changes occurred in 1994 and 1995. Those
changes have substantially limited the amount of net operating loss benefit that
may be utilized in any given taxable year to approximately $30,000 for pre-
January 1994 net operating losses and approximately $180,000 for pre-March 1995
net operating losses. Future changes in the Company's ownership may further
limit the use of the carryforward benefits. There can be no assurance that the
IRS will not challenge the Company's factual and legal determination related to
ownership changes.

7.  Related Party Transactions

     During the years ended December 31, 1994, 1995 and 1996, and the six months
ended June 30, 1997 (unaudited), the Company paid directors of the Company
approximately $85,500, $58,500, $79,800, and $40,700, respectively, for their
services and expenses as Board members and consultants.

     During 1995, the Company paid an additional $54,000 and issued 14,000
shares of common stock to a director of the Company for services performed in
connection with the Series B preferred stock private placement.

8.  Employee Benefits

     During 1995, the Company established a 401(k) defined contribution plan
covering substantially all employees meeting minimum age and service
requirements. Participation in the plan is optional. Employer contributions are
made to the plan solely at the discretion of the Board of Directors. To date, no
Company contributions have been made.

            2000                                            23,800

</TABLE> 

     Rent expense related to the above operating leases approximated $80,000,
$147,500, and $216,800 for the years ended December 31, 1994, 1995 and 1996,
respectively.

10.  Contingencies
    
     Subsequent to December 31, 1996, an interference proceeding was declared 
by the United States Patent and Trademark office between an issued patent and a
patent application of the Company and a patent application by another company
(the "Interference"). The Company's patent and patent application involve
certain technology that is an essential part of its current FraudBuster(R)
product. The Company is currently in negotiations with the other company
regarding the Interference. The Company is currently unable to determine whether
it will be able to settle the Interference on terms satisfactory to the Company
or the ultimate outcome or the range of possible loss in this matter.     

     The Company is currently involved in a dispute in which a customer asserts
it is owed approximately $153,000 in past royalties from the Company. The
Company believes it is owed amounts by the customer for unrecognized services
previously rendered which would fully offset any amount owed to the customer.
The Company is currently unable to predict the ultimate outcome of this matter
or estimate the range of potential loss should an unfavorable outcome occur.

     The outcome of these uncertainties could have a material adverse effect 
on the Company's financial position, results of operations or cash flows.

11.  Stock Offering Costs

     During 1996, the Company incurred $676,100 of costs associated with the
filing of a registration statement with the Securities and Exchange Commission
for the sale of shares of its common stock to the public. Subsequent to December
31, 1996, the Company suspended the initial public offering. As a result, costs
associated with the offering have been expensed in the statement of operations
for the year ended December 31, 1996.

12.  Subsequent Events
    
     Subsequent to December 31, 1996, the Company's financial position has
deteriorated. The Company has incurred a net loss of $2,181,600 and experienced
net cash outflows from operations of $2,022,800 for the six-month period ended
June 30, 1997 (unaudited). At June 30, 1997, the Company has an accumulated
deficit of $11,102,600 (unaudited). As of September 30, 1997, the Company had
exhausted substantially all available lines of credit. As a result, there is
substantial doubt about whether the Company can continue as a going concern.
During July 1997, the Company entered into a plan and agreement of merger with
another company. Management believes that consummation of the merger will
provide the Company with sufficient working capital and other financial
resources to allow the Company to continue operations. If the merger is not
consummated, the Company intends to seek additional financing through sales of
equity instruments, another business combination, or other means.     

     Subsequent to December 31, 1996, the Company drew an additional $240,000 on
the line of credit discussed in Note 4. In addition, on July 22, 1997, the
Company entered into a second line of credit arrangement with a bank for
$530,000, which matures on October 22, 1997. The Company had drawn the entire
amount of its available credit at September 30, 1997.

   This Agreement and Plan of Reorganization dated as of September 9, 1997 (this
"Agreement") is entered into among Lightbridge, Inc., a Delaware corporation
("Lightbridge"), SeeCross Acquisition Corp., a Delaware corporation and wholly
owned subsidiary of Lightbridge ("Acquisition Corp."), and Coral Systems, Inc.,
a Delaware corporation ("Coral").

                                    RECITALS

   The parties hereto desire to effect a reorganization in which Acquisition
Corp. shall be merged into Coral, with the surviving corporation to be a wholly
owned subsidiary of Lightbridge, all of the issued and outstanding shares of
capital stock of Coral ("Coral Capital Stock") to be converted into shares of
common stock, $.01 par value, of Lightbridge ("Lightbridge Common") and all of
the outstanding options and warrants to purchase Coral Capital Stock to become
exercisable (if and when vested) to acquire shares of Lightbridge Common, all
upon the terms and conditions set herein.

   Following the execution of this Agreement, Lightbridge will file with the
Securities and Exchange Commission ("SEC") a registration statement on Form S-4
covering the shares of Lightbridge Common to be issued in the proposed merger.
Upon the effectiveness of such registration statement, Coral will deliver the
proxy statement/prospectus contained in such registration statement to the
holders of Coral Capital Stock in connection with the solicitation of proxies to
approve this Agreement and the merger contemplated hereby.

   Concurrently with the execution of this Agreement and in order to induce
Lightbridge to enter into this Agreement, (i) each of the holders of Coral
Capital Stock designated with an asterisk on Exhibit A is delivering to
                                             ---------
Lightbridge a duly executed voting agreement in the form of Exhibit B (each a
                                                            ---------
"Voting Agreement") pursuant to which, among other things, the executing holder
has granted to certain representatives of Lightbridge an irrevocable proxy to
vote all of the holder's shares of Coral Capital Stock in favor of the approval
of this Agreement and the merger contemplated hereby and (ii) the holders of a
majority of the outstanding shares of each class of Coral Capital Stock have
delivered to Coral an action by consent of stockholders dated as of the date
hereof, pursuant to which such holders have duly approved and adopted a
certificate of amendment to the amended and restated certificate of
incorporation of Coral in the form of Exhibit C (the "Charter Amendment") in
                                      ---------
order to amend and waive certain rights of holders of Coral Capital Stock that
would otherwise apply to the merger contemplated by this Agreement.

   Now, Therefore, Lightbridge, Acquisition Corp. and Coral hereby agree as
follows:

                            ARTICLE 1.  THE MERGER

    Section 1.1. CERTIFICATE OF MERGER.  Subject to and upon the terms and
conditions of this Agreement, and on the basis of the agreements, covenants,
representations and warranties herein contained, at the closing of the
transactions contemplated by this Agreement (the "Closing"), the Surviving
Corporation (as defined in Section 1.6) shall execute a certificate of merger
(the "Certificate of Merger") in substantially the form of Exhibit D, providing
                                                           ---------
for the statutory merger of Acquisition Corp. with and into Coral (the "Merger")
as of the time (the "Effective Time") of filing of the Certificate of Merger
with the Secretary of State of the State of Delaware.  At the Effective Time,
shares of Coral Capital Stock issued and outstanding immediately prior to the
Effective Time will be converted into fully paid and nonassessable shares of
Lightbridge Common, in accordance with Section 1.4.

    Section 1.2. CLOSING DATE.  The Closing shall be held on the business day
following the date of the Coral Stockholders Meeting (as defined in Section 5.2)
and shall take place at the office of Foley, Hoag & Eliot LLP, Boston,
Massachusetts, at 10 A.M., Eastern time, or on such other date, or at such other
time and place, as the parties may agree upon in writing.  The date on which the
Closing is to be held is herein referred to as the "Closing Date."

                                      A-1
<PAGE>
 
    Section 1.3. EFFECTIVE TIME.  Subject to the provisions of this Agreement
and the Certificate of Merger, the Certificate of Merger, together with the
required related certificates, shall be filed in accordance with the applicable
provisions of the Delaware General Corporation Law ("Delaware Law") as soon as
practicable after the Closing.  The Merger shall become effective as of the
Effective Time.

    Section 1.4. EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of any party:

      1.4.1. All of the 1,000 issued and outstanding shares of common stock,
   $.01 par value, of Acquisition Corp. shall be converted into an aggregate of
   1,000 shares of common stock, $.01 par value, of the Surviving Corporation.
   Each stock certificate representing shares of common stock, $.01 par value,
   of Acquisition Corp. prior to the Effective Time shall represent an equal
   number of shares of common stock, $.01 par value, of the Surviving
   Corporation from and after the Effective Time.

      1.4.2.  Each outstanding share of Coral Capital Stock (except Dissenting
   Shares, as defined in Section 1.7.1) shall be converted, subject to the
   indemnification and escrow provisions of Article 7, into the right to receive
   the consideration set forth below.  The maximum number of shares of
   Lightbridge Common to be issued in exchange for the acquisition by
   Lightbridge of all outstanding shares of Coral Capital Stock and for
   reservation upon exercise of all unexpired and unexercised options and
   warrants to acquire Coral Capital Stock shall be the Aggregate Share Number
   (as defined in Section 1.4.4).  No adjustment shall be made in the number of
   shares of Lightbridge Common issued in the Merger as a result of any cash
   proceeds received by Coral from the date hereof to the Effective Time
   pursuant to the exercise of options, warrants or other rights to acquire
   Coral Capital Stock. Subject to the terms and conditions of this Agreement,
   as of the Effective Time, by virtue of the Merger and without any action on
   the part of Acquisition Corp., Coral or the holder of any shares of the Coral
   Capital Stock, the following shall occur:

          (a) Each share of common stock, $.001 par value, of Coral ("Coral
      Common") will be exchanged for the Common Consideration (as defined in
      Section 1.4.4).

          (b) Each share of Series A Preferred Stock, $.001 par value, of Coral
      ("Coral Series A") will be exchanged for the Series A Consideration (as
      defined in Section 1.4.4).

          (c) Each share of Series B Preferred Stock, $.001 par value, of Coral
      ("Coral Series B") will be exchanged for the Series B Consideration (as
      defined in Section 1.4.4).

          (d) Each share of Series C Preferred Stock, $.001 par value, of Coral
      ("Coral Series C") will be exchanged for the Series C Consideration (as
      defined in Section 1.4.4).

          (e) Each outstanding option to purchase shares of Coral Common (each
      an "Option") previously issued under the Coral Systems, Inc. Amended and
      Restated Stock Option Plan adopted August 29, 1996, including the
      predecessor Coral Systems, Inc. Stock Option Plan effective October 27,
      1992 (together, the "Option Plan"), whether vested or unvested, shall
      entitle its holder, upon exercise of such Option (if and when vested)
      following the Effective Time, to receive that number of whole shares of
      Lightbridge Common equal to the product of the number of shares of Coral
      Common that were issuable upon exercise of such Option immediately prior
      to the Effective Time (without regard to vesting) multiplied by the Common
      Consideration, rounded down to the nearest whole number of shares of
      Lightbridge Common.  In addition, following the Effective Time, the per
      share exercise price for the Lightbridge Common issuable upon exercise of
      each Option shall be equal to the quotient of the exercise price per share
      of Coral Common at which such Option was exercisable immediately prior to
      the Effective Time divided by the number of shares of Lightbridge Common
      that constitute the Common Consideration,

                                      A-2
<PAGE>
 
      rounded up to the nearest whole cent. Following the Effective Time, each
      Option shall continue to have, and be subject to, the same terms and
      conditions set forth in the Option Plan and as provided in the option
      agreement governing such Option immediately prior to the Effective Time,
      except as set forth in this Section. It is the intention of the parties
      that the Options qualify following the Effective Time as incentive stock
      options, as defined in Section 422 of the Internal Revenue Code of 1986,
      as amended (the "Code"), to the extent they qualified as incentive stock
      options immediately prior to the Effective Time.

          (f) Each outstanding warrant to purchase shares of Coral Common (each
      a "Warrant"), whether vested or unvested, shall entitle its holder, upon
      exercise of such Warrant (if and when vested) following the Effective
      Time, to receive that number of whole shares of Lightbridge Common equal
      to the product of the number of shares of Coral Common that were issuable
      upon exercise of such Warrant immediately prior to the Effective Time
      (without regard to vesting) multiplied by the Common Consideration,
      rounded down to the nearest whole number of shares of Lightbridge Common.
      In addition, following the Effective Time, the per share exercise price
      for the Lightbridge Common issuable upon exercise of each Warrant shall be
      equal to the quotient of  the exercise price per share of Coral Common at
      which such Warrant was exercisable immediately prior to the Effective Time
      divided by the number of shares of Lightbridge Common that constitute the
      Common Consideration, rounded up to the nearest whole cent.  Following the
      Effective Time, each Warrant shall continue to have, and be subject to,
      the same terms and conditions set forth in the Warrant immediately prior
      to the Effective Time, except as set forth in this Section.

      1.4.3.  No fractional shares of Lightbridge Common shall be issuable in
   connection with the Merger.  The number of shares of Lightbridge Common
   allocable to all outstanding shares of Coral Capital Stock and to be reserved
   for exercise of all Options and Warrants shall equal the Aggregate Share
   Number and, to the extent the calculations pursuant to Section 1.4.2 produce
   fractional shares or an aggregate number greater or less than the Aggregate
   Share Number, the number of shares of Lightbridge Common allocable to
   individual holders of Coral Capital Stock, Options and Warrants shall be
   appropriately adjusted.

      1.4.4. The following terms used in this Section 1.4 shall have the
   indicated meanings:

             (a)  The "Aggregate Preference" shall mean a number of shares of
      Lightbridge Common equal to the quotient of:

                 (i)  the sum of (A) the product of $0.66 multiplied by the
                      number of shares of Coral Common outstanding immediately
                      prior to the Effective Time, (B) the product of $1.00
                      multiplied by the number of shares of Coral Series A
                      outstanding immediately prior to the Effective Time, (C)
                      the product of $2.16 multiplied by the number of shares of
                      Coral Series B outstanding immediately prior to the
                      Effective Time, (D) the product of $2.3207 multiplied by
                      the number of shares of Coral Series C outstanding
                      immediately prior to the Effective Time, and (E) the
                      product of $0.66 multiplied by the number of shares of
                      Coral Common issuable (without regard to vesting) upon the
                      exercise of all unexpired and unexercised Options and
                      Warrants outstanding immediately prior to the Effective
                      Time, divided by

                 (ii) the Calculation Price.

             (b) The "Aggregate Share Number" shall mean a number of shares of
          Lightbridge Common equal to:

                 (ii)  if the Calculation Price is less than $10.8375, the
                       quotient of $13,946,375 divided by the Calculation Price,
                       rounded down to the nearest whole number of shares of
                       Lightbridge Common; or

                 (iii) if the Calculation Price is greater than $14.6625, the
                       quotient of $18,868,625 divided by the Calculation Price,
                       rounded down to the nearest whole number of shares of
                       Lightbridge Common;

          less the number of shares of Lightbridge Common equal to the quotient
          of (A) the Offset Expenses (as defined in Section 5.11) plus the Final
          Adjustment Amount (as defined in Section 1.10) divided by (B) the
          Calculation Price.

             (c) The "Calculation Price" shall equal the average of the last

             (d) The "Common Consideration" shall mean the number of shares of
          Lightbridge Common equal to the sum of (i) $0.66 divided by the
          Calculation Price, plus (ii) the Remainder Amount.

             (e) The "Remainder Amount" shall equal the quotient of (i) the
          Aggregate Share Number minus the Aggregate Preference, divided by (ii)
          the sum of (A) the number of shares of Coral Common outstanding
          immediately prior to the effective time, (B) the number of shares of
          Coral Common into which the shares of Coral Series A outstanding

    Section 1.5. EXCHANGE OF CORAL CERTIFICATES.  Lightbridge hereby appoints
American Stock Transfer & Trust Company to act as exchange agent (the "Exchange
Agent") in the Merger, to act in accordance with the terms hereof and with such
other instructions as Lightbridge may provide from time to time at or prior to
the Closing.  Prior to the filing of the Registration Statement with the SEC,
Lightbridge shall appoint a commercial bank having at least $50,000,000 in
assets and reasonably acceptable to Coral (or American Stock Transfer & Trust
Company) to act as escrow agent (the "Escrow Agent")  in accordance with the
terms hereof and the Escrow Agreement (as defined in Section 6.2.3(e)).  At the
Closing, the holders of Coral Capital Stock (the "Stockholders") shall surrender
to the Exchange Agent the stock certificates (the "Coral Certificates")
representing the outstanding shares of Coral Capital Stock.  As soon as
practicable after the Effective Time, and in any event within five business days
thereafter, Lightbridge shall deliver or cause to be delivered to the Exchange
Agent, stock certificates registered in the names of the Stockholders and
representing a number of shares of Lightbridge Common  (the "Irrevocable
Shares") equal to thirty percent of the maximum Stock Consideration Number
reasonably estimated by Lightbridge to be issuable after giving effect to the
post-closing adjustments provided for in Section 1.10, all as determined to
enable Foley, Hoag & Eliot LLP to deliver the tax opinion contemplated by
Section 6.2.8. As soon as practicable after the Final Adjustment Amount has been
determined pursuant to Section 1.10, Lightbridge shall deliver or cause to be
delivered (i) to the Exchange Agent, stock certificates registered in the names
of the Stockholders and representing a number of shares of Lightbridge Common
equal to the number, if any (the "Additional Shares"), by which (A) one-third of
the Stock Consideration Number exceeds (B) the number of shares delivered
pursuant to the preceding sentence and (ii) to the Escrow Agent, stock
certificates registered in the names of the Escrow Agent and representing a
number of shares (the "Escrow Shares") equal to the portion of the Stock
Consideration Number not delivered to the Exchange Agent pursuant to the
preceding clause (A) and the preceding sentence. Upon the delivery of such stock
certificates to the Exchange Agent and the Escrow Agent, the Coral Certificates
shall forthwith be canceled. On the first business day occurring six months
after the Closing Date, the Exchange Agent shall send to Stockholders who have
duly surrendered their Coral Certificates by overnight courier certificates
representing the Irrevocable Shares and the Additional Shares, if any, provided
that if, in connection with its tax opinion contemplated by Section 6.2.8,
Foley, Hoag & Eliot LLP shall require that the stock certificates representing
the Irrevocable Shares be delivered to Stockholders at an earlier date, the
Exchange Agent shall deliver such certificates at such earlier time to
Stockholders who have duly surrendered their Coral Certificates. In the event
stock certificates representing the Irrevocable Shares are delivered in
accordance with the foregoing proviso, the Irrevocable Shares shall not be
transferable until six months after the Closing Date and such stock certificates
shall bear transfer legends to such effect. Coral shall use reasonable business
efforts to cause all of the Coral Certificates to be surrendered prior to the
Closing; if, however, any of the Coral Certificates are presented to the
Surviving Corporation after the Effective Time for any reason, they shall be
delivered to the Exchange Agent and exchanged in accordance with this Section.
In the event any Coral Certificates shall have been lost, stolen or destroyed,
the Exchange Agent shall issue in exchange for such lost, stolen or destroyed
Coral Certificates, upon the making of an affidavit of that fact by the holder
thereof, the shares of Lightbridge Common issuable with respect thereto pursuant
to Section 1.4, provided that Lightbridge may, in its discretion and as a
condition precedent to the issuance thereof, require such holder to deliver a
bond in such sum as Lightbridge may reasonably direct as indemnity against any
claim that may be made against Lightbridge or the Exchange Agent with respect to
the Coral Certificates alleged to have been lost, stolen or destroyed. The
shares of Lightbridge Common delivered to the Exchange Agent and the Escrow
Agent

                                      A-5
<PAGE>
 
shall be deemed to have been delivered in full satisfaction of all rights
pertaining to the shares of Coral Capital Stock represented by the Coral
Certificates. It is acknowledged that the holders of Coral Capital Stock, by
virtue of the Merger, shall have no further rights as stockholders of Coral or
the Surviving Corporation following the Merger, including any rights pursuant to
(i) the Stock Purchase Agreement dated as of November 1, 1991 by and between
Coral and CVM Equity Fund III, Ltd., (ii) the Series A Convertible Preferred
Stock Purchase Agreement dated as of January 26, 1994 by and between Coral and
the Purchasers named therein, (iii) the Series B Preferred Stock Purchase
Agreement dated as of March 2, 1995 by and among Coral and the Purchasers named
therein, (iv) the Series C Preferred Stock Purchase Agreement dated as of March
21, 1996 by and between Coral and Cincinnati Bell Information Systems Inc. and
(v) the Amended and Restated Investors' Rights Agreement dated as of March 21,
1996 by and among Coral and the Stockholders named therein (collectively, the
"Coral Stockholders Agreements").

    Section 1.6. OTHER EFFECTS.  At the Effective Time:

      (a) the separate existence of Acquisition Corp. shall cease and
          Acquisition Corp. shall be merged with and into Coral, with Coral
          remaining as the surviving corporation (the "Surviving Corporation");

      (b) the certificate of incorporation and by-laws of Acquisition Corp.
          shall be the certificate of incorporation and by-laws of the Surviving
          Corporation;

      (c) the directors and officers of Acquisition Corp. shall be the directors
          and officers of the Surviving Corporation; and

      (d) the Merger shall, from and after the Effective Time, have all of the
          effects provided by Delaware Law.

    Section 1.7. DISSENTING SHARES.

      1.7.1. Notwithstanding any provision of this Agreement to the contrary,
   the shares of Coral Capital Stock of any Stockholder who has demanded and
   perfected appraisal rights for such shares in accordance with Delaware Law
   and who, as of the Effective Time, has not effectively withdrawn or lost such
   appraisal rights ("Dissenting Shares"), shall not be exchanged for or
   represent a right to receive Lightbridge Common pursuant to Section 1.4, but
   the holder thereof shall only be entitled to such rights as are granted by
   Delaware Law.

      1.7.2. Notwithstanding the provisions of Section 1.7.1, if any Stockholder
   who demands appraisal of shares of Coral Capital Stock under Delaware Law
   shall effectively withdraw the right to appraisal, then, as of the later of
   the Effective Time and the occurrence of such event, such shares shall
   automatically be exchanged for and represent only the right to receive
   Lightbridge Common, without interest thereon, upon surrender of the stock
   certificate representing such shares to the Exchange Agent.

      1.7.3.  Coral shall give Lightbridge (a) prompt notice of any written

   such demands, and any other instruments served pursuant to Delaware Law and
   received by Coral which relate to any such demand for appraisal and (b) the
   opportunity to participate in all negotiations and proceedings which take
   place prior to the Effective Time with respect to demands for appraisal under
   Delaware Law.  Coral shall not, except with the prior written consent of
   Lightbridge, voluntarily make any payment with respect to any demands for

    Section 1.8. HOLDERS' AGENT.  Pete Bloomer (or another Person designated by
Coral) shall, by virtue of the Merger and the resolutions to be adopted at the
Coral Stockholders Meeting (as defined in Section 5.2), be irrevocably appointed
attorney-in-fact and authorized and empowered to act, for and on behalf of any
or all of the Stockholders (with full power of substitution in the premises) in
connection with the determination of the Final Adjustment Amount pursuant to
Section 1.10, the indemnity provisions of Article 7 as they relate to the
Stockholders generally, the Escrow Agreement, the notice provisions of this
Agreement and such other matters as are reasonably necessary for the
consummation of the transactions contemplated hereby, including to act as the
representative of the Stockholders to review and authorize all set-offs, claims
and other payments authorized or directed by the Escrow Agreement and dispute or
question the accuracy thereof, to compromise on their behalf with Lightbridge
any claims asserted thereunder and to authorize payments to be made with respect
thereto, and to take such further actions as are authorized in this Agreement.
The above-named representative, as well as any subsequent representative of the
Stockholders appointed by such representative (or, after such representative's
death or incapacity, elected by vote of holders of a majority of Coral Capital
Stock outstanding immediately prior to the Effective Time), is referred to
herein as the "Holders' Agent."  The Holders' Agent shall not be liable to any
Stockholder, Lightbridge, the Surviving Corporation or any other person with
respect to any action taken or omitted to be taken by the Holders' Agent under
or in connection with this Agreement or the Escrow Agreement unless such action
or omission results from or arises out of fraud, gross negligence, willful
misconduct or bad faith or the part of the Holders' Agent.  The Stockholders
shall severally indemnify the Holders' Agent and hold the Holders' Agent
harmless against any loss, liability or expense incurred without fraud, gross
negligence, willful misconduct or bad faith on the part of the Holders' Agent
and arising out of or in connection with the acceptance or administration of the
duties of the Holders' Agent hereunder, including the reasonable fees and
expenses of any legal counsel retained by the Holders' Agent.  Each of
Lightbridge and Acquisition Corp. and each of their respective affiliates shall
be entitled to rely on such appointment and treat the Holders' Agent as the duly
appointed attorney-in-fact of each Stockholder.  Each Stockholder who votes in
favor of the Merger pursuant to the terms hereof, by such vote, without any
further action, and each Stockholder who receives shares of Lightbridge Common
in connection with the Merger, by acceptance thereof and without any further
action, confirms such appointment and authority and acknowledges and agrees that
such appointment is irrevocable and coupled with an interest, it being
understood that the willingness of Lightbridge and Acquisition Corp. to enter
into this Agreement is based, in part, on the appointment of a representative to
act on behalf of the Stockholders.

    Section 1.9. DISTRIBUTIONS.  Subject to applicable law, no dividends or
other distributions with respect to Lightbridge Common declared or made after
the Effective Time and with a record date after the Effective Time will be paid
to the holder of any unsurrendered Coral Certificate with respect to the shares
of Lightbridge Common represented thereby until the holder of record of such
Coral Certificate shall surrender such Coral Certificate.  Subject to applicable
law, following surrender of any such Coral Certificate, there shall be paid to
the record holder of shares of Lightbridge Common issued in exchange therefor,
without interest, at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore
payable with respect to such shares of Lightbridge Common, provided that any
stock dividend shall not be delivered to such recordholder prior to the
delivery, pursuant to this Agreement, of the Lightbridge Common on which such
stock dividend was declared.

    Section 1.10. POST-CLOSING BALANCE SHEET ADJUSTMENT.

      1.10.1.  Following the Closing Date, Lightbridge and the Surviving
   Corporation will prepare a balance sheet of Coral as of immediately prior to
   the time of the Closing (the "Preliminary Closing Balance Sheet").  The
   Preliminary Closing Balance Sheet will be prepared in accordance with
   generally accepted accounting principles applied on a basis, and using
   methodologies, consistent with the Financial Statements (as defined in
   Section 2.6), except that the Preliminary Closing Balance Sheet may omit
   footnotes and related disclosures normally contained in audited balance
   sheets prepared in accordance with generally accepted accounting principles.
   Lightbridge will then cause Deloitte &

                                      A-7
<PAGE>
 
   Touche LLP, Lightbridge's independent accountants ("Lightbridge's
   Accountants"), to audit the Preliminary Closing Balance Sheet and to issue
   their report thereon, and Lightbridge will reflect in the Preliminary Closing
   Balance Sheet such adjustments, if any, as are proposed by Lightbridge's
   Accountants based upon their audit.

      1.10.2.  On or before the forty-fifth day following the Closing Date,
   Lightbridge will deliver to the Holders' Agent the Preliminary Closing
   Balance Sheet, the audit report of Lightbridge's Accountants with respect
   thereto, and a statement of the Preliminary Adjustment Amount.  The
   Preliminary Adjustment Amount shall be the difference between negative
   $1,245,500 and the working capital (total current assets less total current
   liabilities) of Coral as reflected on the Preliminary Closing Balance Sheet;
   provided, however, that the Preliminary Adjustment Amount shall not reflect
   any reductions in the working capital of Coral attributable to any of the
   items listed in Section 1.10 of the Schedule.

      1.10.3.  Within fifteen days after his receipt of the Preliminary Closing
   Balance Sheet and statement of the Preliminary Adjustment Amount, the
   Holders' Agent shall notify Lightbridge whether he accepts or disputes the
   Preliminary Adjustment Amount.  If the Holders' Agent accepts the Preliminary
   Closing Balance Sheet and the Preliminary Adjustment Amount, or fails to
   notify Lightbridge of any dispute with respect thereto within said fifteen-
   day period, the Preliminary Closing Balance Sheet shall be deemed to be the
   "Final Closing Balance Sheet" and the Preliminary Adjustment Amount shall be
   deemed to be final, conclusive and binding upon the parties (the "Final
   Adjustment Amount").  During such fifteen-day period and until the
   determination of the Final Adjustment Amount, the Holders' Agent will be
   provided with access to such financial books and records of Coral as he may
   reasonably request in order to confirm the accuracy of the Preliminary
   Closing Balance Sheet.  If the Holders' Agent disputes the accuracy of the
   Preliminary Closing Balance Sheet or the Preliminary Adjustment Amount, he
   shall in such notice set forth in reasonable detail those items that he
   believes are not fairly presented in conformity with Section 1.10.1 above and
   the reasons for his opinion.  The parties shall then meet and in good faith
   use their best efforts to try to resolve their disagreements over the
   disputed items.  If the parties resolve their disagreements over the disputed
   items in accordance with the foregoing procedure, the Preliminary Closing
   Balance Sheet and the Preliminary Adjustment Amount, with those modifications
   to which the parties shall have agreed, shall be deemed to be the Final
   Closing Balance Sheet and the Final Adjustment Amount.  If the parties have
   not resolved their disagreements over the disputed items on the Preliminary
   Closing Balance Sheet or the Preliminary Adjustment Amount within fifteen
   days after the notice of dispute from the Holders' Agent, the parties shall
   forthwith jointly request an independent, national accounting firm mutually
   agreed upon by Lightbridge's Accountants and the Holders' Agent (the
   "Accounting Arbitrator") to make a binding determination of those disputed
   items in accordance with this Agreement.  The Accounting Arbitrator will have
   no more than forty-five days from the date of referral and no more than
   thirty days from the final submission of information or testimony by the
   parties to render its decision with respect to the disputed items concerning
   the Preliminary Closing Balance Sheet and the Preliminary Adjustment Amount,
   which decision shall be final and binding upon the parties and enforceable as
   an arbitration award pursuant to the Massachusetts Uniform Arbitration Act
   for Commercial Disputes, Mass. Gen. Laws Ann. ch. 251 or the Federal
   Arbitration Act, 9 U.S.C. (S)(S)1 et seq.  The Preliminary Closing Balance
   Sheet and the Preliminary Adjustment Amount, with those adjustments
   determined by the Accounting Arbitrator to be necessary, shall be deemed to
   be the Final Closing Balance Sheet and the Final Adjustment Amount.  The fees
   and expenses of the Accounting Arbitrator engaged pursuant to this Section
   shall be borne equally by the Stockholders and by Lightbridge (with the
   portion attributable to the Stockholders being treated as an additional
   Offset Expense, further decreasing the Aggregate Share Number pursuant to
   Section 1.4.4).

    Section 1.11. TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time
after the Effective Time, any such further action is necessary or desirable to
carry out the purposes of this Agreement and to vest the 

                                      A-8
<PAGE>
 
Surviving Corporation with full right, title and possession to all assets,
property, rights, privileges, powers and franchises of Coral and Acquisition
Corp., the officers and directors of Coral and Acquisition Corp. are fully
authorized in the name of their respective corporations or otherwise to take,
and shall take, all such lawful and necessary action.

    Section 1.12. TAX TREATMENT.  The parties intend that the Merger shall be
treated as a reorganization under Section 368 of the Code.

              ARTICLE 2.  REPRESENTATIONS AND WARRANTIES OF CORAL

   Coral hereby represents and warrants to Lightbridge and Acquisition Corp. as
follows, subject to such exceptions as are specifically disclosed under
appropriate section headings in the disclosure schedule attached hereto and made
a part hereof (the "Schedule"):

    Section 2.1. CORPORATE STATUS.  Coral is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware,
with all requisite corporate power to own, lease and operate its properties and
to carry on its business as now being conducted.  Coral is duly qualified to do
business as a foreign corporation, and is in good standing, in each other
jurisdiction in which it owns or leases property or conducts business, except
where the failure to be so qualified does not have any effect that is, or is
reasonably likely to be, materially adverse to its business, results of
operations, properties, assets, liabilities, prospects or condition (financial
or otherwise) (a "Coral Material Adverse Effect").

    Section 2.2. CORPORATE DOCUMENTS.  Coral has delivered to Lightbridge true
and complete copies of its amended and restated certificate of incorporation, as
amended to date (the "Coral Charter"),  and its bylaws, as amended to date (the
"Coral Bylaws").  The Coral Charter and the Coral Bylaws are in full force and
effect, and no further amendment or restatement thereof has been adopted or
proposed, except for the Charter Amendment.  Coral is not in Violation of any
provision of the Coral Charter or the Coral Bylaws. The minute books and stock
records of Coral, which have heretofore been made available to Lightbridge, are
true and complete and are the only minute books and stock records of Coral.  The
Schedule sets forth the current directors and officers of Coral.

    Section 2.3. CAPITAL STRUCTURE.  The authorized Coral Capital Stock consists
of (a) 30,000,000 shares of Coral Common, of which 3,276,234 shares are
outstanding as of the date hereof; (b) 2,000,000 shares of Coral Series A, of
which 2,000,000 shares are outstanding as of the date hereof; (c) 2,083,333
shares of Coral Series B, of which 2,083,333 shares are outstanding as of the
date hereof; (d) 1,850,000 shares of Coral Series C, of which 1,824,920 shares
are outstanding as of the date hereof; and (e) 9,066,667 shares of preferred
stock, $.001 par value, none of which have been designated in series or are
outstanding as of the date hereof.  No shares of Coral Capital Stock are held as
treasury stock.  The name of each Stockholder, and the number and class of
shares of Coral Capital Stock owned of record by such Stockholder, are set forth
on the Schedule.  All of the outstanding shares of Coral Capital Stock are duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights created by statute, the Coral Charter, the Coral Bylaws or any
agreement to which Coral is a party or is bound.  No bonds, debentures, notes or
other indebtedness of Coral having the right to vote (or convertible into
securities having the right to vote) on any matters on which holders of Coral
Capital Stock may vote ("Voting Debt") have been issued or are outstanding.
Except for the Option Plan, Coral has never adopted or maintained any stock
option plan or other plan providing for equity compensation of any person.
Coral has reserved 2,089,189 shares of Coral Common for issuance to employees
and consultants pursuant to the Option Plan, of which 1,186,544 shares are
subject to outstanding, unexercised Options as of the date hereof and 696,874
shares remain available for future grant as of the date hereof.  The name of
each holder of an Option or a Warrant, and the grant date of the Option or
Warrant and the number of shares of Coral Common for which the Option or Warrant
is exercisable, are set forth on the Schedule.  Coral has never accelerated the
vesting schedule of any of the outstanding Options, and no Option will be
accelerated and become exercisable by

                                      A-9
<PAGE>
 
reason of the transactions contemplated by this Agreement. All shares of Coral
Common subject to issuance under the Options and the Warrants, upon issuance on
the terms and conditions specified in the Options or Warrants pursuant to which
they are issuable, shall be duly authorized, validly issued, fully paid and
nonassessable. Coral is not a party to or bound by: (a) any option, warrant,
call, right or agreement, other than the Options and the Warrants, obligating
Coral to issue, deliver or sell additional shares of Coral Capital Stock or
Voting Debt or to grant, extend, accelerate the vesting of, change the price of,
otherwise amend or enter into any such option, warrant, call, right or
agreement; (b) any voting trust, proxy or other agreement or understanding with
respect to the voting of shares of Coral Capital Stock; or (c) any other
agreement restricting the transfer of, or affecting rights with respect to,
shares of Coral Capital Stock. The holders of the Options and the Warrants have
been or will be given, or shall have properly waived, any required notice prior
to the Merger.

    Section 2.4. AUTHORITY.

      2.4.1. Coral has all requisite corporate power to execute and deliver this
   Agreement and each of the Certificate of Merger, the Employment Agreements
   and the Non-Competition Agreement (each as defined herein and collectively
   the "Coral Corollary Agreements") and to consummate the transactions
   contemplated hereby and thereby. Subject only to the approval of this
   Agreement by the Stockholders, the execution and delivery of this Agreement
   and the Coral Corollary Agreements, and the consummation of the transactions
   contemplated hereby and thereby, have been duly and validly authorized by all
   requisite corporate action on the part of Coral and no other corporate
   proceedings on the part of Coral are necessary to authorize the execution and
   delivery of this Agreement or any of the Coral Corollary Agreements or to
   consummate the transactions contemplated hereby and thereby. Without limiting
   the foregoing, the Charter Amendment has been duly approved by the
   Stockholders. The vote required of the Stockholders to duly approve the
   Merger and this Agreement is a majority of the outstanding shares of the
   Coral Common and a majority of the outstanding shares of the Coral Series A,
   Coral Series B and Coral Series C, voting as a single class. The board of
   directors of Coral has unanimously approved the Merger, this Agreement and
   the Charter Amendment. This Agreement has been duly and validly executed and
   delivered by Coral and constitutes a legal, valid and binding obligation of
   Coral enforceable in accordance with its terms, all as may be subject to or
   affected by any bankruptcy, reorganization, insolvency, moratorium or similar
   laws of general application from time to time in effect and relating to or
   affecting the rights or remedies of creditors generally (the "Creditor
   Exception"). As of the Closing Date, each of the Coral Corollary Agreements
   will be duly and validly executed and delivered by Coral and will constitute
   a legal, valid and binding obligation of Coral enforceable in accordance with
   its terms, all as may be subject to or affected by the Creditor Exception.

      2.4.2. Subject only to the approval of this Agreement and the filing of
   the Charter Amendment with the Secretary of State of the State of Delaware,
   the execution and delivery by Coral of this Agreement do not, and the
   execution and delivery by Coral of the Coral Corollary Agreements and the
   consummation by Coral of the transactions contemplated hereby and thereby
   will not, result in any Violation (as defined below) of any provision of the
   Coral Charter, the Coral Bylaws, any material Contract (as defined in Section
   2.10), any of the Permits (as defined in Section 2.7), or any judgment,
   order, decree, statute, law, ordinance, rule or regulation of any
   Governmental Entity (as defined below) applicable to Coral or its properties
   or assets. Coral does not have any plans, programs or agreements to which it
   is a party or subject pursuant to which payments may be required or
   acceleration of benefits may be required upon a change of control of Coral.
   No consent, approval, order or authorization of, or registration, declaration
   or filing with, any Governmental Entity is required by or with respect to
   Coral at or prior to the Effective Time in connection with the execution and
   delivery by Coral of this Agreement or any of the Coral Corollary Agreements
   or the consummation by Coral of the transactions contemplated hereby and
   thereby, except for (i) the filing of the Charter Amendment and the
   Certificate of Merger with the Secretary of State of the State of Delaware
   and (ii) the filing of the Registration Statement (as defined in Section 5.1)
   with the SEC in accordance with the

                                     A-10
<PAGE>
 
   Securities Act of 1933, as amended (the "Securities Act"). As used herein:
   "Violation" means, with respect to a provision, (A) any material conflict
   with, material violation of or material default (with or without notice or
   lapse of time, or both) under such provision, (B) the arising of any right of
   termination, cancellation or acceleration of any obligation, or loss of any
   material benefit, under such provision, or (C) the arising of any material
   lien, pledge, claim, charge, security interest, mortgage, easement,
   servitude, refusal, claim of infringement or other restriction or encumbrance
   of any kind, including any restriction on use, voting (in the case of any
   security), transfer, receipt of income or exercise of any other attribute of
   ownership on assets; and "Governmental Entity" means any domestic or foreign
   court, administrative agency or commission, or other governmental authority
   or instrumentality.

    Section 2.5. INVESTMENTS.  Coral does not directly or indirectly own, or
have the right to acquire, any equity interest or investment in the equity
capital of any Person (as defined below).  Coral has no obligation to acquire
any class of securities (including debt securities) issued by any Person.  Coral
has not owned or controlled any subsidiary corporation or any stock or other
interest in any Person and is not a party to, and has not been a party to, or
bound by any partnership, joint venture, voluntary association, cooperative or
business trust agreement or arrangement other than in the ordinary course of
business.  Coral has delivered or made available to Lightbridge true and
complete copies of any such agreements or arrangements that were entered into in
the ordinary course of business and any provision of which is currently in
effect.  As used herein, "Person" means any individual, corporation,
partnership, firm, joint venture, association, joint-stock company, trust,
unincorporated organization, Governmental Entity or any other entity.

    Section 2.6. FINANCIAL STATEMENTS.

      2.6.1.  The audited balance sheets of Coral at each of December 31, 1994,
   1995 and 1996 and the related audited statements of operations, changes in
   stockholders' equity and cash flows for the years then ended (including the
   notes thereto), and the unaudited balance sheets of Coral at June 30, 1996
   and 1997 and the related unaudited statements of operations, changes in
   stockholders' equity and cash flows for the six-month periods then ended
   (including the notes thereto), as provided by Coral to Lightbridge, have been
   prepared in accordance with generally accepted accounting principles, applied
   on a consistent basis throughout the periods involved (except that the
   unaudited financial statements do not contain all the notes that may be
   required by generally accepted accounting principles and were or are subject
   to normal and recurring year-end adjustments that were not or are not
   expected to be material in amount), and fairly present in all material
   respects the financial condition of Coral as at the dates thereof and the
   results of its operations and its cash flows for the periods then ended.  As
   used herein, "Financial Statements" means all of such financial statements
   and notes collectively, "1997 Balance Sheet" means the unaudited balance
   sheet of Coral at June 30, 1997, and "1997 Financial Statements" means the
   1997 Balance Sheet and the related unaudited financial statements of Coral
   for the six months ended June 30, 1997 (including the notes thereto).  The
   1997 Financial Statements have been reviewed (but not audited) by Price
   Waterhouse LLP, independent accountants to Coral, in accordance with the
   procedures specified by the American Institute of Certified Public
   Accountants for a review of interim financial information as described in
   Statement on Auditing Standards No. 71, "Interim Financial Information."  The
   books of account of Coral have been prepared and maintained in accordance
   with Coral's normal practice, consistent in all material respects with the
   accounting principles and policies reflected in the Financial Statements.

      2.6.2.  All accounts receivable reflected on the 1997 Balance Sheet and
   Coral's books and records as of the date hereof represent sales actually made
   in the ordinary course of business and in a manner consistent with Coral's
   regular credit practices.  The reserve for doubtful accounts reflected on the
   1997 Balance Sheet has been established based upon and consistent with past
   practice and is, in Coral's reasonable judgment, adequate.

                                     A-11
<PAGE>
 
      2.6.3.  Coral has no outstanding Indebtedness (as defined below) or other
   liabilities, asserted liabilities or obligations of any nature, whether
   absolute, accrued, contingent or otherwise, other than (a) those disclosed or
   reflected on the 1997 Financial Statements, (b) those not required under
   generally accepted accounting principles to be disclosed or reflected on the
   1997 Financial Statements and (c) those incurred since June 30, 1997 in the
   ordinary course of business consistent with past practice. Without limiting
   the foregoing, Coral does not have any outstanding monetary obligations to
   either AirTouch Communications, Inc. or Cincinnati Bell Information Systems
   Inc. or their respective affiliates under Contracts existing as of, or
   terminated prior to, the date of this Agreement.  Coral does not have any
   outstanding Indebtedness for borrowed money.  For purposes of this Agreement,
   "Indebtedness" means (i) all items (except items of capital stock,
   stockholders' equity, surplus or retained earnings, and general contingency
   reserves) that in accordance with generally accepted accounting principles
   would be included in determining total liabilities as shown on the liability
   side of a balance sheet of Coral as at the date as of which such Indebtedness
   is to be determined, (ii) all indebtedness secured by any mortgage, pledge,
   lien, security interest or conditional sale or other title retention
   agreement to which any property or asset owned or held by Coral is subject,
   whether or not the indebtedness secured thereby shall have been assumed, and
   (iii) all indebtedness of others which Coral has directly or indirectly
   guaranteed, endorsed (otherwise than for collection or deposit in the
   ordinary course of business), sold or discounted with recourse or
   (contingently or otherwise) to purchase or repurchase or otherwise acquire,
   or in respect of which Coral has agreed to supply or advance funds (whether
   by way of loan, stock purchase, capital contribution or otherwise) or
   otherwise become directly or indirectly liable.

    Section 2.7. COMPLIANCE WITH APPLICABLE LAWS.  Coral holds all permits,
licenses, variances, certificates of occupancy, exemptions, orders, approvals
and authorizations of all Governmental Entities that are material to the
operation of its business (the "Permits").  All of the Permits are in full force
and effect, and Coral has delivered or made available to Lightbridge true and
complete copies of all of the Permits. Coral is in compliance with the terms of
the Permits, except where any such failure so to comply, individually or in the
aggregate with any other such failures, would not have a Coral Material Adverse
Effect. No Violation of any of the Permits has been alleged by any Governmental
Entity, and no proceeding is pending, or to the knowledge of Coral threatened,
to revoke, suspend, cancel or limit any of the Permits.  No action by Coral,
Lightbridge, the Surviving Corporation or any other party is required in order
that all of the Permits will remain in full force and effect following the
Merger.  The business of Coral is not being conducted in violation of or
conflict with any law, ordinance or regulation or any order, judgment,
injunction, award or decree of any Governmental Entity (collectively "Laws"),
except where any such violation or conflict, individually or in the aggregate,
would not have a Coral Material Adverse Effect and except for Environmental
Laws, which are the subject of Section 2.18.  As of the date of this Agreement,
no investigation or review by any Governmental Entity with respect to Coral is
pending or, to the knowledge of Coral, threatened, nor has any Governmental
Entity indicated an intention to conduct the same, and, to Coral's knowledge,
the continued use, occupancy and operation of the Leased Real Property (as
defined in Section 2.9.2) as currently used, occupied and operated does not
constitute a nonconforming use under any Law.  Coral has no knowledge of any
pending or anticipated change in any Law which would have a material adverse
effect upon the current ownership, use, occupancy or operation of the Leased
Real Property or any portion thereof.

    Section 2.8. LITIGATION.  There is no claim, dispute, action, suit, appeal,
legal, administrative or arbitral proceeding, or investigation, at law or in
equity, pending against Coral, or involving any of its assets or properties,
before any court, agency, authority, arbitration panel or other tribunal, and,
to the knowledge of Coral, none has been threatened.  To the knowledge of Coral,
there are no facts that, if known to customers, Governmental Entities or other
Persons, could reasonably be expected to result in any such claim, dispute,
action, suit, appeal, legal, administrative or arbitral proceeding, or
investigation that could reasonably be expected to have a Coral Material Adverse
Effect.  Coral is not named as a subject of any order, writ, injunction or
decree of any court, agency, authority, arbitration panel or other tribunal, nor
is it

                                     A-12
<PAGE>
 
in default with respect to any notice, order, writ, injunction or decree. No
judgment has been entered by, and no claim, dispute, action, suit, appeal,
legal, administrative or arbitral proceeding, or investigation, at law or in
equity, is pending or, to the knowledge of Coral, threatened that materially and
adversely affects, or could reasonably be expected to materially and adversely
affect, the ability of Coral to perform under this Agreement or that seeks to
enjoin or prohibit any of the transactions contemplated by this Agreement.

    Section 2.9. PROPERTIES.

      2.9.1.  Owned Properties.  Coral does not own and has never owned any real
   property.

      2.9.2. Leased Properties. The Schedule sets forth a true and complete list
   of all leases, subleases, licenses, revocable use permits and other
   agreements (collectively, the "Real Property Leases") under which Coral uses
   or occupies any real property (the land and improvements covered by the Real
   Property Leases being herein called the "Leased Real Property"), which
   Schedule sets forth the date of and parties to each Real Property Lease.
   Coral has heretofore delivered to counsel for Lightbridge true and complete
   copies of all Real Property Leases, including all modifications thereof and
   all amendments and supplements thereto. Each Real Property Lease is valid,
   binding and in full force and effect, no written notice of default or
   termination thereunder is outstanding with respect to any Real Property
   Lease, all rent and other material sums due and payable by Coral under each
   Real Property Lease are current, with respect to each Real Property Lease
   Coral is not in material default in its obligations, and no event has
   occurred nor condition exists which, with the giving of notice or the lapse
   of time or both, would constitute a material default by Coral under any Real
   Property Lease. Coral holds the leasehold estate under and interest in each
   Real Property Lease free and clear of all liens, charges and encumbrances
   (together, "Encumbrances") except for (a) Encumbrances reflected in the 1997
   Financial Statements (including overleases, governmental development plans
   and similar agreements to which Coral is not a party), (b) Encumbrances
   securing taxes, assessments, governmental charges or levies, or the claims of
   materialmen, carriers, landlords and like persons, all of which are not yet
   due and payable, (c) restrictions on use contained in Real Property Leases
   that do not materially restrict the property subject thereto from being used
   as such property is currently used or (d) imperfections of title and other
   minor Encumbrances that do not materially detract from the value or impair
   the use of the asset subject thereto or impair the operations of Coral
   (collectively, the Encumbrances described in clauses (a), (b), (c) and (d)
   shall be referred to as "Permitted Encumbrances"). Neither Coral nor any its
   officers, directors or Stockholders has any ownership, financial or other
   interest in the landlord under any Real Property Lease. Each Real Property
   Lease was negotiated on an arm's-length basis on commercially reasonable
   terms.

      2.9.3.  Entire Premises.  All of the land, buildings, structures and other
   improvements used by Coral in the conduct of Coral's business (the
   "Improvements") are included in the Leased Real Property.  To the knowledge
   of Coral, Coral has taken no action and has suffered no action to occur that
   would materially adversely affect the interest of Coral in the Leased Real
   Property.  Coral does not own or hold, and is not obligated under or a party
   to, any option, right of first refusal or other contractual right to
   purchase, acquire, sell or dispose of the Leased Real Property or any portion
   thereof or interest therein.

      2.9.4.  Personal Property.  The 1997 Balance Sheet reflects all of the
   material personal property used by Coral in its business or otherwise held by
   Coral, except for personal property acquired in the ordinary course of
   business by Coral since June 30, 1997 and personal property not required
   under generally accepted accounting principles to be reflected on the 1997
   Balance Sheet.  Coral has good and marketable title to, or adequate rights or
   licenses to use, all of the personal property listed on the 1997 Balance
   Sheet or thereafter acquired, in each case free and clear of any imperfection
   of title, lien, claim or encumbrance, except for (a) any lien, claim or
   encumbrance securing taxes, assessments, governmental charges or levies, or
   the claims of materialmen, carriers, landlords and like Persons, all

                                     A-13
<PAGE>
 
   of which are not yet due and payable, and (b) imperfections of title and
   other minor liens, claims and encumbrances that do not materially detract
   from the value or impair the use of the asset subject thereto.

      2.9.5.  Condition of Property.  The Leased Real Property and the owned and
   leased personal property of Coral necessary to the conduct of its business
   are in good operating condition and repair, ordinary wear and tear excepted.
   The Leased Real Property and personal property of Coral are sufficient for
   the continued operation of the business of Coral after the Closing in
   substantially the same manner as conducted prior to the Closing.

      2.9.6. Condemnation. To the knowledge of Coral, there is no threatened or
   contemplated condemnation proceeding affecting the Leased Real Property or
   any part thereof or any sale or other disposition of the Leased Real Property
   or any part thereof in lieu of condemnation.

      2.9.7.  Casualty.  No portion of the Leased Real Property has suffered any
   material damage by fire or other casualty which has not heretofore been
   substantially repaired and restored to its original condition.

      2.9.8.  Space Leases.  Coral has not entered into any lease, sublease,
   license or other agreement granting to any person other than Coral any right
   to the possession, use, occupancy or enjoyment of the Leased Real Property or
   any portion thereof.

    Section 2.10. CONTRACTS.  As used herein, "Contracts" means written
agreements, contracts, instruments, guaranties, powers of attorney, commitments,
understandings, arrangements, promises, assurances, obligations or undertakings

      2.11.1  Coral has timely filed in accordance with applicable law all Tax
   Returns (as defined below) required to be filed by or with respect to it, its
   operations and assets, and all Taxes (as defined below) shown as due on such
   Tax Returns have been paid.  All Tax Returns filed by Coral with respect to
   Taxes were prepared in compliance with all applicable laws and regulations
   and were true and complete in all material respects as of the date on which
   they were filed or as subsequently amended to the date hereof.  Coral has
   provided or otherwise made available to Lightbridge true and complete copies
   of federal, state, local and foreign Tax Returns of Coral for each of the
   years ended December 31, 1996, 1995 and 1994 and all revenue agent's reports
   and other written assertions of deficiencies or other liabilities for Taxes
   with respect to past periods for which the applicable statute of limitations

   of their first being received by Coral.

      2.11.2. Coral has timely paid, or will timely pay on or prior to the

   (in each case, whether or not shown on any Tax Return), except for Taxes that
   are being contested in good faith by appropriate proceedings (all of which
   are set forth on the Schedule) or for payment of which Taxes adequate
   reserves are reflected on the 1997 Balance Sheet.

                                     A-15
<PAGE>
 
      2.11.3  Coral has complied in all material respects with all applicable
   laws, rules and regulations relating to the withholding of Taxes and has
   timely collected or withheld and paid over (and up to the Closing Date will
   have timely collected or withheld and paid over) to the proper Governmental
   Entities all amounts required to be so collected or withheld and paid over
   for all periods up to the Closing Date under all applicable laws.  There are
   not currently in effect any waivers or extensions of any applicable statute
   of limitations for the assessment or collection of Taxes with respect to any
   Tax Return that relates to Coral, and no request for any such waiver or
   extension is pending. There are no Tax rulings, requests for rulings or
   closing agreements relating to Coral that could affect its liability for
   Taxes for any period after the Closing Date.

      2.11.4  Coral has no current or potential contractual obligation to
   indemnify any other Person with respect to Taxes, and has no obligation to
   make distributions in respect of Taxes.  No claim has ever been made by a
   taxing authority in a jurisdiction where Coral does not file Tax Returns that
   Coral is or may be subject to taxation by such jurisdiction.  No power of
   attorney has been granted by Coral with respect to any matter relating to

taxing authority in connection with any Taxes.

    Section 2.12. BENEFIT PLANS.

      2.12.1  The Schedule sets forth a true and complete list of all employee
   benefit plans (whether or not they constitute employee benefit plans within
   the meaning of section 3(3) of Title IV of Employee Retirement Income
   Security Act of 1974, as amended), arrangements, policies or commitments
   (including any employment, consulting or deferred compensation agreement,
   executive compensation, bonus, incentive, pension, profit-sharing, savings,
   retirement, stock option, stock purchase or severance pay plan, any life,
   health, disability or accident insurance plan, or any holiday or vacation
   practice) as to which Coral or any Commonly Controlled Entity has any direct
   or indirect, actual or contingent liability (each a "Benefit Plan").  Coral
   has, with respect to each Benefit Plan, delivered to Lightbridge, where
   applicable, true and complete copies of:  (a) all plan texts and agreements
   and related trust agreements or annuity contracts; (b) all summary plan
   descriptions and material employee communications; (c) the most recent annual
   report (Form 5500 series, including all schedules thereto); (d) the most
   recent actuarial valuation; (e) the most recent annual audited financial
   statement and opinion; (f) if the plan is intended to qualify under Code
   section 401(a) or 403(a), the most recent determination letter received from
   the Internal Revenue Service (the "IRS"); and (g) all material communications
   with any Governmental Entity, including the Pension Benefit Guaranty
   Corporation (the "PBGC") and the IRS.

      2.12.2 No Benefit Plan is subject to Title IV of Employee Retirement
   Income Security Act of 1974, as amended ("ERISA"), or to Code section 412 or
   is a defined benefit plan within the meaning of ERISA section 3(35) or Code
   section 414(i). Coral and any entity which is under common control with Coral
   within the meaning of Code section 414(b), (c), (m) or (o) (a "Commonly
   Controlled Entity") has made all payments due from it to date with respect to
   each Benefit Plan. All amounts properly accrued as liabilities to or expenses
   of any Benefit Plan that have not been paid have been properly reflected on
   the 1997 Financial Statements. Each Benefit Plan conforms to, and its

                                     A-16
<PAGE>
 
   administration is in material compliance with, all applicable laws and
   regulations. There are no actions, liens, suits or claims pending or
   threatened (other than routine claims for benefits) with respect to any
   Benefit Plan. Each Benefit Plan which is intended to qualify under Code
   section 401(a) or 403(a) so qualifies. No event has occurred, and there
   exists no condition or set of circumstances, that presents a material risk of
   a partial termination (within the meaning of Code section 411(d)(3)) of any
   Benefit Plan. Coral does not have any Benefit Plan that is a "group health
   plan" (as defined in ERISA section 607(1)). No assets of Coral are allocated
   to or held in a "rabbi trust" or similar funding vehicle. Coral does not have
   any Benefit Plan that is a welfare plan within the meaning of ERISA section
   3(1) (regardless of whether the plan is covered by ERISA) and that provides
   benefits to current or former employees beyond their retirement or other
   termination of service (other than coverage mandated by COBRA, the cost of
   which is fully paid by the current or former employee or his dependents); and
   there exists no (a) unfunded benefit obligations with respect to any employee
   of Coral which are not fairly reflected by reserves shown on Coral's most
   recent financial statements or (b) reserves, assets, surpluses or prepaid
   premiums with respect to any Benefit Plan that is a welfare plan within the
   meaning of ERISA section 3(1) (regardless of whether the plan is covered by
   ERISA).

      2.12.3. The consummation of the transactions contemplated by this
   Agreement will not (a) entitle any current or former any individual employed
   by Coral or any Commonly Controlled Entity to severance pay, unemployment
   compensation or any similar payment, (b) accelerate the time of payment or
   vesting, or increase the amount of any compensation due to, any current or
   former employed by Coral or any Commonly Controlled Entity, (c) constitute or
   involve a prohibited transaction (as defined in ERISA section 406 or Code
   section 4975), constitute or involve a breach of fiduciary responsibility
   within the meaning of ERISA section 502(1) or otherwise violate Part 4 of
   Title I of ERISA or (d) result in the payment of compensation that would, in
   combination with any other payment, result in an "excess parachute payment"
   within the meaning of Code section 280G(b).

      2.12.4. As of the Closing, neither Coral nor any Commonly Controlled
   Entity has incurred any liability or obligation under the Worker Adjustment
   and Retraining Notification Act, as it may be amended from time to time, and
   within the six-month period immediately following the Closing, neither will
   incur any such liability or obligation if, during such six-month period, only
   terminations of employment in the normal course of operations occur.

      2.12.5.  With respect to the Benefit Plans, individually and in the
   aggregate, no event has occurred, and to the knowledge of Coral, there exists
   no condition or set of circumstances in connection with which Coral could be
   subject to any material liability under ERISA, the Code or any other
   applicable law that is reasonably likely to have a Coral Material Adverse
   Effect, other than any liability for benefits claims and funding obligations
   payable in the ordinary course.

      2.12.6.  With respect to the Benefit Plans, there are no funded benefit
   obligations for which contributions have not been made or properly accrued
   and there are no unfunded benefit obligations that have not been accounted
   for by reserves, or otherwise properly footnoted in accordance with generally
   accepted accounting principles, on the 1997 Balance Sheet, except for
   obligations that are not, individually and in the aggregate, reasonably
   likely to have a Coral Material Adverse Effect.

    Section 2.13. ABSENCE OF CERTAIN EVENTS.  Except as contemplated by this
Agreement, since June 30, 1997, Coral has conducted its business only in the
ordinary course consistent with past practice. Without limiting the generality
of the foregoing, during such period:

   (a) neither the business, properties nor assets of Coral have suffered a
       material adverse loss (whether or not covered by insurance) as the result
       of fire, explosion, earthquake, accident, labor trouble, condemnation or
       taking of property by any Governmental Entity, flood, windstorm,
       pestilence, embargo, riot, act of God or the public enemy or any other
       casualty or similar event;

       ordinary course of business;

       its business, including any write-off or other compromise of any material
       account receivable of Coral;

       liabilities before the same became due in accordance with its terms or

   (k) Coral has not made any loan or advance to any of its Stockholders,
       officers, directors, employees, consultants, agents or other

       of business), or made any other loan or advance otherwise than in the
       ordinary course of business consistent with past practice;

   (l) Coral has not pledged or otherwise, voluntarily or involuntarily,
       encumbered any of its assets or properties, except for liens for current
       taxes which are not yet delinquent and purchase-money liens arising out
       of the purchase or sale of products made in the ordinary and usual course
       of business and in any event not in excess of $25,000 for any single item
       or $50,000 in the aggregate;

   (m) Coral has not materially changed any of its accounting methods,
       principles or procedures;

   (n) Coral has not materially changed any of its business policies or
       practices, including advertising, marketing, pricing, purchasing,
       personnel, sales or budget policies;

   (o) Coral has not suffered or incurred any damage, destruction or loss,
       whether or not covered by insurance, which will have or could reasonably
       be expected to have a Coral Material Adverse Effect; and

   (p) Coral has not entered into any agreement to do any of the foregoing.

   (f) "On-site" shall mean any property owned, leased, or operated by Coral;

   (g) "Release" shall mean any release, spill, emission, leaking, pumping,

    Section 2.19. INSURANCE.  Coral has delivered or made available to
Lightbridge true and complete copies of all insurance policies or binders to
which Coral is a party or under which Coral is covered and true and complete
copies of all applications for insurance policies submitted by Coral.  All
insurance policies to which Coral is a party or that provide coverage to Coral
are in full force and effect.  Since September 1, 1995, Coral has not received
any refusal of coverage, or any notice of suspension, revocation, modification
or cancellation or any other indication that any insurance policy is no longer
in full force or effect or that the issuer of any policy is not willing or able
to perform its obligations thereunder or any notice from an insured to
discontinue any coverage afforded to Coral and, to the knowledge of Coral, there
is no basis for the issuance of any such notice or the taking of any such
action.  Coral has paid all premiums due and has otherwise performed all of its
respective obligations under each such policy, except such as will not
materially adversely affect Coral's coverage thereunder.  There was no claim in
excess of $5,000 asserted under any of the insurance policies of Coral for the
period from September 1, 1995 to the date hereof.  Coral is not party to, or
bound by, any Contract requiring Coral (a) to name a third party as loss payee
under any insurance policy or binder held by or on behalf of Coral or otherwise
requiring Coral to obtain insurance for or on behalf of any third party or (b)
to provide coverage to third parties (such as, for example, under leases or
service agreements).  There is no written self-insurance arrangement by or
affecting Coral.

    Section 2.20. EMPLOYEE RELATIONS.  Coral has never been a party to a
collective bargaining agreement and has never made any final or binding offer to
a labor union or association representing its employees with respect to any
terms or conditions of employment.  Coral has never had, nor is there now
threatened, a union organizing effort, strike, picket, organized work stoppage
or organized work slowdown. Coral has complied with all applicable laws relating
to employment, equal opportunity, nondiscrimination, immigration, wages, hours,
benefits, collective bargaining, the payment of social security and similar
taxes, occupational safety and health, and plant closings, except where the
failure so to be in compliance would not have a Coral Material Adverse Effect.

    Section 2.21. PROPRIETARY RIGHTS.

      2.21.1.  Coral owns, or is licensed or otherwise possesses legally
   enforceable rights to use, all patents, trademarks, trade names, service
   marks, copyrights, and any applications therefor, maskworks,

                                     A-21
<PAGE>
 
   schematics, technology, know-how, computer software programs or applications
   (in both source code and object code form), and tangible or intangible
   proprietary information or material (excluding Commercial Software, as
   defined below) that are material to the business of Coral as currently
   conducted or as proposed to be conducted by Coral (the "Proprietary Rights"),
   free and clear of any and all liens, claims and encumbrances.

      2.21.2. The Schedule sets forth a complete list of all patents,
   trademarks, registered copyrights, trade names and service marks, and any
   applications therefor, owned by Coral and included in the Proprietary Rights,
   specifying, where applicable, the jurisdictions in which each such
   Proprietary Right has been issued or registered or in which an application
   for such issuance and registration has been filed, including the respective
   registration or application numbers and the names of all registered owners.
   None of Coral's currently marketed software products has been registered for
   copyright protection with the United States Copyright Office or any foreign
   offices nor has Coral been requested to make any such registration. Coral has
   provided or made available to Lightbridge true and complete copies of all
   material licenses, sublicenses and other agreements as to which Coral is a
   party and pursuant to which Coral or any other person is authorized to use
   any Proprietary Right (excluding End-User Licenses, as defined below) or
   other trade secret material to Coral. Coral is not in Violation of any such
   license, sublicense or agreement except for such Violations that do not, in
   the aggregate, materially impair Coral's rights under such license,
   sublicense or agreement. Coral is not contractually obligated to pay any
   compensation to any third party in respect of the Proprietary Rights, the use
   thereof or the material covered thereby in connection with the services or
   products in respect of which the Proprietary Rights are being used. No claims
   with respect to the Proprietary Rights have been asserted or, to the
   knowledge of Coral, are threatened by any person nor are there any valid
   grounds, to the knowledge of Coral, for any material claims that are
   reasonably likely to be successful (a) to the effect that the business of
   Coral as currently conducted or as proposed to be conducted by Coral,
   including Coral's design, development, use, import, manufacture and sale of
   the products, technology (including products or technology currently under
   development) or services of Coral, infringes on or misappropriates any valid
   copyright, patent, trademark, service mark, trade secret or other valid
   proprietary rights of any other Person or constitutes unfair competition or
   trade practices under any Law, (b) against the use by Coral of any
   trademarks, service marks, trade names, trade secrets, copyrights, patents,
   technology, know-how or computer software programs and applications used in
   Coral's business as currently conducted or as proposed to be conducted by
   Coral, or (c) challenging the ownership by Coral, validity or effectiveness
   of any of the Proprietary Rights. All registered trademarks, service marks
   and copyrights owned by Coral and included in the Proprietary Rights are
   valid and subsisting, all necessary registration, maintenance and renewal
   fees in connection with such Proprietary Rights have been paid and all
   necessary documents and certificates in connection with such Proprietary
   Rights have been filed with the relevant Governmental Entities for the
   purposes of maintaining such Proprietary Rights. The Schedule lists all
   actions that must be taken by Coral within 120 days following the date
   hereof, including the payment of any registration, maintenance or renewal
   fees or the filing of any documents, applications or certificates required in
   connection with the maintenance, perfection, preservation or renewal of any
   Proprietary Rights. There is no material unauthorized use, infringement or
   misappropriation of any of the Proprietary Rights by any employee or former
   employee of Coral or, to Coral's knowledge, any other third party. No
   Proprietary Right or material product of Coral is subject to any outstanding
   decree, order, judgment, or stipulation restricting in any manner the
   licensing thereof by Coral. There are no Contracts between Coral and any
   other Person with respect to Proprietary Rights under which there is any
   dispute known to Coral regarding the scope of such Contract, or performance
   under such Contract, including with respect to any payments to be made or
   received by Coral thereunder.

      2.21.3.  To the extent that any Proprietary Rights have been developed or
   created by a third party for which Coral has, directly or indirectly, paid,
   Coral has a written agreement with such third party with respect thereto and
   Coral thereby has obtained valid ownership of or rights sufficient for the

                                     A-22
<PAGE>
 
   conduct of Coral's business to all such Proprietary Rights by operation of
   law or by valid assignment or license, except where failure to do so would
   not have a Coral Material Adverse Effect.   Each employee, officer and
   consultant of Coral has executed a confidentiality agreement in substantially
   the form provided to Lightbridge, providing Coral with title and ownership to
   Proprietary Rights developed or used by such person in the conduct of Coral's
   business.  All of such agreements are legal, valid, binding and enforceable
   in accordance with their terms, all as may be subject to or affected by the
   Creditor Exception.  No employee, officer or consultant of Coral is in
   Violation of any provision of any employment or consulting contract,
   proprietary information and inventions agreement, non-competition agreement,
   or any other contract or agreement relating to the relationship of any such
   employee, officer or consultant with Coral or, to the knowledge of Coral, any
   previous employer.

indemnity claims in excess of $50,000 have been made against Coral at any time
since its incorporation.

   Section 2.25.  BUSINESS ACTIVITY RESTRICTIONS.  There is no agreement
(noncompetition or otherwise), commitment, judgment, injunction, order or decree
to which Coral is a party or otherwise binding upon Coral that has or reasonably
could be expected to have the effect of prohibiting or impairing the conduct of
Coral's business as presently conducted or as proposed to be conducted.  Coral

   (ii) cancel, with the consent of the holder thereof but without the delivery
        or payment of any consideration, any Option held by a person who is a

        terms, expire as of the Effective Time as a result of the termination of
        such person's position as a director of Coral; and

        option under the Option Plan that shall (A) have an exercise price of
        $1.50 per share, (B) be exercisable for an aggregate number of shares
        such that the value of the new option is equal to the value of the
        canceled Option, as determined and agreed upon by Broadview Associates
        LLC and Cowen & Company using a Black-Scholes valuation methodology and

responsible for prosecuting the Interference on behalf of Coral, subject to the
approval of Coral, which approval shall not be unreasonably withheld.
Lightbridge and the Interference Counsel shall be responsible for determining
the manner in which to proceed in the Interference, including the identification

that (a) Lightbridge and the Interference Counsel shall consult with Coral from
time to time and as reasonably requested by Coral and shall advise Coral of the
progress of the Interference and (b) the final form of the filing with respect
to the Interference shall be subject to the approval of Coral, which consent
shall not be unreasonably withheld or delayed.  In connection with the
Interference, Coral shall (i) render to Interference Counsel such assistance as
such Interference Counsel may reasonably request, (ii) make Coral's attorneys
and other representatives available to the Interference Counsel and (iii)
provide the Interference Counsel with copies of all books, records and other

purposes of this Agreement, to be expenses incurred by Lightbridge in connection
in with this Agreement. In the event that this Agreement is terminated pursuant
to Section 8.1, Lightbridge agrees that Coral may, in its discretion and at its
expense, elect to have the Interference Counsel continue to represent Coral in
the Interference after the date of termination. Nothing in this Section 5.15

attorney-client or attorney work product privilege in any material respect,
after giving effect to any "common interests" or other legal doctrine that may
apply to Coral and Lightbridge.

defend and hold harmless Lightbridge and the Surviving Corporation (and their
respective affiliates, officers, directors, employees, representatives and
agents) against and in respect of any and all claims, costs, losses, expenses,
liabilities or other damages, including interest and penalties (collectively
"Damages"), that Lightbridge or the Surviving Corporation (or such affiliates,
officers, directors, employees, representatives and agents) shall suffer or
incur, whether liquidated or unliquidated, accrued or contingent, by reason of
or otherwise arising out of:

   (a) any misrepresentation or inaccuracy in, or breach of, any representation
       or warranty contained in this Agreement, including the Schedule hereto or
       any certificates delivered by Coral pursuant to this Agreement, in each
       case as each such representation or warranty (other than the
       representation and warranty contained in the certificate delivered
       pursuant to Section 6.2.1 confirming the statements made in the third
       sentence of Section 6.2.1) would read if all qualifications as to
       materiality or Coral Material Adverse Effects were deleted therefrom,
       provided that this clause(a) shall not apply to any representation or
       warranty made in Section 2.4.1 with respect to the Employment Agreements
       or the Non-Competition Agreement;

   (b) any breach of any covenant, agreement or obligation of Coral contained in
       this Agreement;

   (c) any monetary payment required to be made by the Surviving Corporation
       after the Closing Date that (i) arises out of Contracts between Coral and
       AirTouch Communications, Inc., Cincinnati Bell Information Systems Inc.
       or any of their respective affiliates, (ii) relates to events occurring
       or facts in existence on or prior to the Closing Date and (iii) is not
       reflected on the Final Closing Balance Sheet; or

   (d) any matter set forth in the supplemental escrow letter dated as of the
       date hereof between Lightbridge and Coral.

The amounts for which Lightbridge and the Surviving Corporation may seek
indemnification under this Article 7 shall extend to, and as used herein the
term "Damages" shall include, reasonable attorneys' and accountants' fees and
disbursements, costs of litigation (including court costs and fees of expert
witnesses) and other expenses incurred by them (or their respective affiliates,
officers, directors or employees) in the defense of any claim asserted against
them (or their respective affiliates, officers, directors or employees) and any
amounts paid in settlement or compromise of any claim asserted against them to
the extent that the claim asserted is or would have been subject to the
indemnification provisions hereof, subject to the limitations on total
indemnification set forth in Section 7.4.

    Section 7.2. SURVIVAL OF INDEMNITY.  The indemnification obligations of the
Stockholders pursuant to Sections 7.1(a), (b) and (c) shall survive the Closing
and continue for all Damages as to which Lightbridge has given written notice
thereof to each of the Stockholders, on or prior to the date one year from the
Closing Date; provided, however, that indemnification obligations of the
Stockholders for breach of the

                                     A-37
<PAGE>
 
representations and warranties contained in Sections 2.11 and 2.18 shall
continue until the expiration of the applicable statutes of limitation and the
covenants contained in Section 5.5 (to the extent of a breach by Coral's
accountants, counsel and other Persons acting as representatives of Coral prior
to the Effective Time) shall continue until the fifth anniversary of the date
hereof. Upon expiration of such statutes, the Stockholders shall have no
liability for Damages under such indemnification obligation unless Lightbridge
has given written notice as required. The indemnification obligations of the
Stockholders pursuant to Section 7.1(d) shall survive the Closing and continue
for all Damages as to which Lightbridge has given written notice thereof to each
of the Holders' Agent, on or prior to the date eighteen month from the Closing
Date.

    Section 7.3. ESCROW.  At the Closing, Lightbridge, Coral, the Holders' Agent
and the Escrow Agent shall enter into the Escrow Agreement pursuant to which
Lightbridge shall issue to the Escrow Agent the Escrow Shares.  To the extent
any of the parties named in Section 7.1 may be entitled to indemnification
under Section 7.1 as a result of any Damages, Lightbridge shall be entitled to
set off and apply against such Damages the Escrow Shares in accordance with the
terms of the Escrow Agreement and this Article 7. Pursuant to the terms of the
Escrow Agreement, the Escrow Shares shall be valued at any time, for purposes of
set off against any Damages, at the Calculation Price.

    Section 7.4. ADDITIONAL PROVISIONS.  The Stockholders shall have no
obligation to indemnify Lightbridge or the Surviving Corporation with respect to
the matters described in Section 7.1(a), (b) or (c) except to the extent that
the aggregate cumulative amount of any Damages with respect to those matters
exceeds $150,000.  The Stockholders' liability for indemnification under this
Article 7 or otherwise by reason of or arising out of any breach by Coral of any
covenant that does not survive the Closing or of any representation or warranty
shall be limited as follows:  (a) recovery under the Escrow Agreement shall be
limited to an aggregate dollar amount equal to the number of Escrow Shares,
multiplied by the Calculation Price and (b) recovery with respect to any
Stockholder shall be limited to an aggregate of the product of the Calculation
Price multiplied by the aggregate number of shares of Lightbridge Common which
such Stockholder receives pursuant to Section 1.4.  Such liability of the
Stockholders for indemnification shall not be modified, waived or diminished by
any examination or investigation conducted by Lightbridge of the books, records
or operations of Coral.  Nothing in this Article 7 or otherwise shall limit, in
any manner, any remedy at law or equity, to which Lightbridge may be entitled as
a result of fraud by Coral, any of the Stockholders or any employee, officer or
director of Coral.  Notwithstanding the foregoing, the Stockholders' liability
for a misrepresentation or inaccuracy in, or breach of, the representations and
warranties contained in Section 2.1 shall not be limited in any way under this
Article 7 or otherwise.

    Section 7.5. SURVIVAL OF REPRESENTATIONS AND WARRANTIES AND COVENANTS.  The
representations and warranties of Coral shall survive until one year after the
Closing Date, except for the representations and warranties in Sections 2.11 and
2.18, which shall survive until the expiration of the applicable statutes of
limitations.  The representations and warranties of Lightbridge and Acquisition
Corp. shall terminate immediately as of the Closing.  The covenants of any party
shall terminate according to the terms thereof.

                  DELAWARE GENERAL CORPORATION LAW SECTION 262

SECTION 262. APPRAISAL RIGHTS.

   (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to sec. 228 of this
title shall be entitled to an appraisal by the Court of Chancery of the fair
value of the stockholder's shares of stock under the circumstances described in
subsections (b) and (c) of this section.  As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

   (b) Appraisal rights shall be available for the shares of any class or series
of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
subsection (g) of sec. 251 of this title), 252, 254, 257, 258, 263 or 264 of
this title:

       (1) Provided, however, that no appraisal rights under this section shall
   be available for the shares of any class or series of stock, which stock, or
   depository receipts in respect thereof, at the record date fixed to determine
   the stockholders entitled to receive notice of and to vote at the meeting of
   stockholders to act upon the agreement of merger or consolidation, were
   either (i) listed on a national securities exchange or designated as a
   national market system security on an interdealer quotation system by the
   National Association of Securities Dealers, Inc. or (ii) held of record by
   more than 2,000 holders; and further provided that no appraisal rights shall
   be available for any shares of stock of the constituent corporation surviving
   a merger if the merger did not require for its approval the vote of the
   stockholders of the surviving corporation as provided in subsection (f) of
   sec. 251 of this title.

       (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
   under this section shall be available for the shares of any class or series
   of stock of a constituent corporation if the holders thereof are required by
   the terms of an agreement of merger or consolidation pursuant to sec. 251,
   252, 254, 257, 258, 263 and 264 of this title to accept for such stock
   anything except:

           a.  Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

           b.  Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock or depository receipts at the
       effective date of the merger or consolidation will be either listed on a
       national securities exchange or designated as a national market system
       security on an interdealer quotation system by the National Association
       of Securities Dealers, Inc. or held of record by more than 2,000 holders;

           c.  Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or

           d.  Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.


       (3) In the event all of the stock of a subsidiary Delaware corporation
   party to a merger effected under sec. 253 of this title is not owned by the
   parent corporation immediately prior to the merger, appraisal rights shall be
   available for the shares of the subsidiary Delaware corporation.
<PAGE>
 
   (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

   (d) Appraisal rights shall be perfected as follows:

       (1) If a proposed merger or consolidation for which appraisal rights are
   provided under this section is to be submitted for approval at a meeting of
   stockholders, the corporation, not less than 20 days prior to the meeting,
   shall notify each of its stockholders who was such on the record date for
   such meeting with respect to shares for which appraisal rights are available
   pursuant to subsections (b) or (c) hereof that appraisal rights are available
   for any or all of the shares of the constituent corporations, and shall
   include in such notice a copy of this section.  Each stockholder electing to
   demand the appraisal of his shares shall deliver to the corporation, before
   the taking of the vote on the merger or consolidation, a written demand for
   appraisal of his shares.  Such demand will be sufficient if it reasonably
   informs the corporation of the identity of the stockholder and that the
   stockholder intends thereby to demand the appraisal of his shares.  A proxy
   or vote against the merger or consolidation shall not constitute such a
   demand.  A stockholder electing to take such action must do so by a separate
   written demand as herein provided.  Within 10 days after the effective date
   of such merger or consolidation, the surviving or resulting corporation shall
   notify each stockholder of each constituent corporation who has complied with
   this subsection and has not voted in favor of or consented to the merger or
   consolidation of the date that the merger or consolidation has become
   effective; or

       (2) If the merger or consolidation was approved pursuant to sec. 228 or
   253 of this title, each constituent corporation, either before the effective
   date of the merger or consolidation or within ten days thereafter, shall
   notify each of the holders of any class or series of stock of such
   constituent corporation who are entitled to appraisal rights of the approval
   of the merger or consolidation and that appraisal rights are available for
   any or all shares of such class or series of stock of such constituent
   corporation, and shall include in such notice a copy of this section;
   provided that, if the notice is given on or after the effective date of the
   merger or consolidation, such notice shall be given by the surviving or
   resulting corporation to all such holders of any class or series of stock of
   a constituent corporation that ore entitled to appraisal rights.  Such notice
   may, and, if given on or after the effective date of the merger or
   consolidation, shall, also notify such stockholders of the effective date of
   the merger or consolidation.  Any stockholder entitled to appraisal rights
   may, within 20 days after the date of mailing of such notice, demand in
   writing from the surviving or resulting corporation the appraisal of such
   holder's shares.  Such demand will be sufficient if it reasonably informs the
   corporation of the identity of the stockholder and that the stockholder
   intends thereby to demand the appraisal of such holder's shares.  If such
   notice did not notify stockholders of the effective date of the merger or
   consolidation, either (i) each such constituent corporation shall send a
   second notice before the effective date of the merger or consolidation
   notifying each of the holders of any class or series of stock of such
   constituent corporation that are entitled to appraisal rights of the
   effective date of the merger or consolidation or (ii) the surviving or
   resulting corporation shall send such a second notice to all such holders on
   or within 10 days after such effective date; provided, however, that if such
   second notice is sent more than 20 days following the sending of the first
   notice, such second notice need only be sent to each stockholder who is
   entitled to appraisal rights and who has demanded appraisal of such holder's
   shares in accordance with this subsection.  An affidavit of the secretary or
   assistant secretary or of the transfer agent of the corporation that is
   required to give either notice that such notice has been given shall, in the
   absence of fraud, be prima facie evidence of the facts stated therein. For
   purposes of determining the stockholders entitled to receive either notice,
   each constituent corporation may fix, in advance, a record date that shall be
   not more than 10 days prior to the date the notice is given, provided, that
   if the notice is given on or after the effective date of the merger or
   consolidation, the record date shall be such effective date. If no record
   date is fixed and the notice is given prior to the effective date, the record
   date shall be the close of business on the day next preceding the day on
   which the notice is given.

   (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders.  Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares.  Such written statement
shall be mailed to the stockholder within 10 days after his written request for
such a statement is received by the surviving or resulting corporation or within
10 days after expiration of the period for delivery of demands for appraisal
under subsection (d) hereof, whichever is later.

   (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation.  If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list.  The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated.  Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable.  The
forms of the notices by mail and by publication shall be approved by the Court,
and the costs thereof shall be borne by the surviving or resulting corporation.

   (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights.  The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

   (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value.  In determining such fair value, the
Court shall take into account all relevant factors.  In determining the fair
rate of interest, the Court may consider all relevant factors, including the
rate of interest which the surviving or resulting corporation would have had to
pay to borrow money during the pendency of the proceeding.  Upon application by
the surviving or resulting corporation or by any stockholder entitled to
participate in the appraisal proceeding, the Court may, in its discretion,
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal.  Any stockholder whose name appears on the list filed by the
surviving or resulting corporation pursuant to subsection (f) of this section
and who has submitted his certificates of stock to the Register in Chancery, if
such is required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.

   (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may direct.  Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock.  The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

                                      B-3
<PAGE>
 
   (j) The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances.  Upon application
of a stockholder, the Court may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorney's fees and the fees and expenses of
experts, to be charged pro rata against the value of all of the shares entitled
to an appraisal.

   (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

   (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
