                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note l -- Basis of Presentation

   These consolidated financial statements for the three and nine months 
ended September 30, 1996 and the related footnote information are unaudited 
and have been prepared on a basis substantially consistent with the audited 
consolidated financial statements of PSINet Inc. and subsidiaries 
(collectively, "PSINet" or the "Company") as of December 31, 1995 
incorporated by reference in the Company's Annual Report on Form 10-K as 
filed with the Securities and Exchange Commission (the "Annual Report").  
These financial statements should be read in conjunction with the audited 
consolidated financial statements and the related notes to consolidated 
financial statements of the Company as of December 31, 1995 incorporated by 
reference in the Company's Annual Report and the unaudited quarterly 
consolidated financial statements and related notes to consolidated financial 
statements of the Company for the periods ended March 31, 1996 and June 30, 
1996 included in the Company's Quarterly Reports on Form 10-Q, as filed with 
the Securities and Exchange Commission.  In the opinion of management, the 
accompanying unaudited financial statements contain all adjustments 
(consisting of normal recurring adjustments) which management considers 
necessary to present fairly the consolidated financial position of the 
Company at September 30, 1996 and the results of operations for the three and 
nine month periods ended September 30, 1995 and 1996 and the consolidated 
cash flows for the nine month periods ended September 30, 1995 and 1996. The 
results of operations for the three and nine month periods ended September 
30, 1996 may not be indicative of the results expected for any succeeding 
quarter or for the entire year ending December 31, 1996.

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the amounts reported in the financial statements.  
Actual results may differ from those estimates.

Note 2 -- Loss per Share and Pro Forma Loss per Share
   
   Loss per share is computed using the weighted average number of shares of 
common stock, adjusted for the dilutive effect of common stock equivalent 
shares of common stock options and warrants.  Common stock equivalent shares 
are calculated using the treasury stock method.

   Pro forma loss per share is computed using the weighted average number of 
shares of common stock, adjusted for the dilutive effect of common stock 
equivalent shares of common stock options and warrants and assuming the 
conversion of redeemable preferred and common stock as of the beginning of 
the period presented.  

Note 3 -- Short-term Investments and Marketable Securities
   
   The Company classifies its investment holdings in debt and equity 
securities as either held-to-maturity securities, trading securities or 
available-for-sale securities and reports the investments at amortized cost, 
fair value with unrealized gains and losses included in earnings and fair 
value with unrealized gains and losses included in shareholders' equity, 
respectively.  
   
   At September 30, 1996, short-term investments and marketable securities 
included debt securities classified as held-to-maturity with original 
maturities of greater than 90 days of approximately $11.5 million.

                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 3 -- Short-term Investments and Marketable Securities (continued)

   In August 1995, the Company entered into an agreement to form a joint 
venture with Hansol Paper Co. Ltd. ("Hansol Paper"), of Seoul, Korea for the 
purpose of building an Internet network and providing Internet-related 
services in Korea. In March 1996, pursuant to these arrangements, the Company 
acquired a 10% interest in Hansol Telecom Co., Ltd. ("Hansol"), an affiliate 
of Hansol Paper, for approximately $3.1 million.  This investment is 
reflected in short-term investments and marketable securities.
   
    Other income for the nine months ended September 30, 1996 consists of 
approximately $2.9 million of realized gains on equity securities sold by the 
Company.

Note 4 -- Long-term Debt

   During the nine months ended September 30, 1996, the Company incurred 
capital lease obligations of approximately $30.4 million upon the execution 
of leases for new data communications equipment and other fixed assets.
   
   Effective August 13, 1996, the Company entered into an amendment to a 
borrowing facility obtained in November 1994, which increased the Company's 
maximum borrowing availability under the facility from $13.5 million to $18.5 
million for purchases of computer equipment and other fixed assets.  
Borrowings under this facility are repayable in 36 monthly installments from 
the dates of equipment purchases and are secured by a lien on the equipment 
purchased.  Interest is payable monthly at a rate of prime plus 2.5% (10.75% 
at September 30, 1996). The borrowing facility contains certain restrictions 
which, among other things, require the maintenance of certain financial 
ratios and restrict the payment of dividends.
   
   At September 30, 1996, the aggregate unused portion under the Company's 
various financing arrangements for purchases of data communications equipment 
and other fixed assets was $11.5 million. 
   
   Additionally, the Company has a secured revolving credit agreement with a 
bank under which the Company may borrow up to a maximum principal amount of 
the lesser of $5.0 million or 75% of qualified accounts receivable which 
secure the loan less 20% of aggregate principal of certain term credit 
advances (approximately $4.1 million at September 30, 1996). There was $2.0 
million advanced under this credit agreement at September 30, 1996.  Interest 
is payable monthly at a rate of prime plus 1.5% (9.75% at September 30, 1996).

Note 5 -- Agreements with MindSpring Enterprises, Inc.

   On June 28, 1996, the Company entered into an agreement with 
MindSpring Enterprises, Inc., an Atlanta, GA based Internet access provider 
("MindSpring"), pursuant to which the Company agreed to transfer to 
MindSpring certain of its individual subscriber accounts and related tangible 
and intangible assets and rights in connection with the consumer dial-up 
Internet access services operated by the Company in the United States.  In 
connection with the transfer, the parties also entered into a Network 
Services Agreement pursuant to which the Company agreed to 
service certain of MindSpring's individual subscribers through local dial-in 
POPs connected to the Company's network.  As part of these agreements, the 
Company also has the option to transfer to MindSpring individual subscriber 
accounts generated in the future.

                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 5 -- Agreements with MindSpring Enterprises, Inc. (continued)
   
   Under the terms of these agreements, as amended, the Company transferred 
certain of its individual subscriber accounts as of June 28, 1996 for $3.0 
million, consisting of $1.0 million cash and a $2.0 million Convertible Note 
(the "First Note"), which was included in revenue or other income, net in 
June 1996.  The First Note bears interest at a rate of prime plus 3.0% 
(11.25% at September 30, 1996).  In accordance with the terms of these 
agreements, due to the fact that the First Note was not redeemed in full 
before ninety days after the date of the First Note (September 28, 1996), the 
principal amount of the First Note was increased by five percent.  
   
   Additionally, under the terms of these agreements, the Company transferred 
substantially all of the remainder of its individual subscriber accounts and 
certain assets located at the Company's customer service facility in New 
Cumberland, Pennsylvania as of September 1, 1996 in exchange for a $9.9 
million Convertible Note (the "Second Note"), which was included in revenue 
or other income, net of related asset costs and transfer expenses in 
September 1996.  The Second Note bears interest at a rate of prime plus 3.0% 
(11.25% at September 30, 1996).  Until the Second Note is redeemed in full, 
the outstanding principal amount thereof will increase by five percent each 
ninety days commencing ninety days after the date of the Second Note.  If  
the Second Note is not redeemed in full by September 1, 1997, the Company has 
the right to convert, at the option of the Company subject to certain 
limitations, the total amount due under the Second Note into common stock of
MindSpring.
   
   The total amount of consideration received for the transfer of subscribers 
as of September 1, 1996 is subject to adjustment based upon the number of 
subscribers transferred to MindSpring who remain customers of MindSpring and 
current in their payments for services at a scheduled measurement date.  
Additional individual subscriber accounts generated (up to an 
aggregate of 100,000 including those previously transferred) through November 
30, 1996 may be transferred for additional consideration, subject to 
adjustment as described above.
   
   Under the terms of these agreements, in October 1996, the Company received 
$9.2 million in cash from MindSpring as payment in full on the First Note and 
partial payment on the Second Note.  

Note 6 -- Agreements with Chatterjee Management Company
   
   On September 19, 1996,  the Company entered into an agreement with 
Chatterjee Management Company (doing business as The Chatterjee Group), a 
Delaware corporation ("Chatterjee"), pursuant to which the Company and an 
investment group led by Chatterjee (the "Chatterjee Investor Group") would 
establish a joint venture to be known as PSINet Europe (the "Joint Venture") 
for the purpose of building an Internet network across Europe and providing 
Internet-related services in Europe. 

   Under the agreement, expected contributions of up to $5.98 million cash 
and up to 100% of the stock of PSINet's UK subsidiary, PSINet UK Limited, by 
the Company, and up to $41.1 million cash by the Chatterjee Investor Group, 
are to be made from time to time in exchange for equity interests in the 
Joint Venture, which will be adjusted at the times of such contributions.  
Under certain circumstances, the Chatterjee Investor Group has the right to 
exchange its interest in the Joint Venture for shares of the Company's common 
stock.   The Company and Chatterjee have entered into a registration rights 
agreement with respect to such shares.

   It also is contemplated that the Company and the Joint Venture will enter 
into agreements whereby the Company will, among other things, license certain 
intellectual property to the Joint Venture and provide operational support 
and assistance to the Joint Venture.  The Company and Chatterjee are in the 
process of negotiating terms and conditions for these transactions.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS
               
The following discussion should be read in conjunction with the accompanying 
unaudited Consolidated Financial Statements and associated Notes thereto and 
the audited Consolidated Financial Statements, the Notes thereto and 
Management's Discussion and Analysis of Financial Condition and Results of 
Operations of the Company as of December 31, 1995 incorporated by reference 
to the Company's Annual Report on Form 10-K and the unaudited quarterly 
consolidated financial statements and related notes to consolidated financial 
statements of the Company for the periods ended March 31, 1996 and June 30, 
1996 included in the Company's Quarterly Reports on Form 10-Q for such 
periods, as filed with the Securities and Exchange Commission.  This 
discussion includes certain forward-looking statements.  Actual results could 
differ materially from the forward-looking statements as a result of a number 
of factors.  For a discussion of the risk factors that could cause actual 
results to differ materially from the forward-looking statements, see "Risk 
Factors" set forth in Exhibit 99.1 filed herewith and the Company's other 
filings with the Securities and Exchange Commission.

GENERAL

The Company provides Internet access, services and products throughout the 
United States and internationally. The Company offers a broad spectrum of 
Internet access services ranging from dial-up services to continuous access 
services using dedicated high-speed telephone circuits. In addition, the 
Company offers Web site design and hosting services, training and consulting 
services, Internet access security services and client software products. The 
Company also began offering Internet access services to other Internet 
service providers ("ISPs") and entered into arrangements during the second 
quarter of 1996 with another ISP for the transfer of substantially all of the 
Company's individual customer accounts in connection with the implementation 
of a new strategy for servicing individual subscribers.  See "Consumer 
Wholesale Strategy".  At September 30, 1996, the Company had approximately 
15,100 business subscribers, approximately 11,700 professional subscribers 
and serviced approximately 170,900 consumer wholesale subscribers, through 
more than 345 network local access points called Points-of-Presence or 
"POPs."   

Since the commencement of the Company's operations in 1989, the Company has 
undertaken a program of developing and expanding its network. In connection 
with this development and expansion, the Company has made significant 
investments in telecommunications circuits and equipment. These investments 
generally are made significantly in advance of anticipated subscriber growth 
and resulting revenue. The Company also increased its sales and marketing, 
customer support, network operations and field services commitments in 
anticipation of the expansion of its subscriber base.  These expansion 
efforts have caused the Company to experience increases in expenses from time 
to time, both in absolute terms and as a percentage of  revenue, in 
anticipation of potential future growth in the Company's subscriber base.  
The nature and amount of these expenses may fluctuate over time as the 
Company shifts its focus from network expansion efforts to enhancement of its 
existing network.

The Company's operating results have fluctuated in the past and they may 
continue to fluctuate in the future as a result of a variety of factors, some 
of which are beyond the Company's control. As of September 30, 1996, the 
Company had an accumulated deficit of $99.8 million.  The Company believes 
that it will incur losses throughout 1996, and there can be no assurance that 
the Company will achieve profitability in the future. 




                                      9

CONSUMER WHOLESALE STRATEGY

In response to competitive considerations with respect to consumer dial-up 
Internet access services, the Company has altered its strategy to include 
providing wholesale access services to consumer-oriented providers of 
Internet access and services in the United States, rather than providing the 
consumer access services directly.  Pursuant to network access agreements 
with other providers, the Company provides Internet connection services to 
other providers and their subscribers through the PSINet network POPs.  The 
Company does not currently anticipate that it will incur significant capital 
expenditures in order to service its existing wholesaling arrangements.  The 
agreements call for the other providers to pay specified fees for each 
subscriber using the PSINet network.

In connection with the introduction of its new strategy relating to consumer 
dial-up Internet access services, as indicated above, the Company 
restructured its operations and eliminated certain positions relating to 
these services.  There were no significant restructuring charges relating to 
this new strategy.  The impact of the reduction in costs and expenses 
associated with this restructuring is expected to occur in periods after 
September 30, 1996.

On June 28, 1996, the Company entered into an agreement with MindSpring 
Enterprises, Inc., an Atlanta-based Internet access provider ("MindSpring"), 
pursuant to which the Company agreed to transfer to MindSpring substantially 
all of its individual subscriber accounts and related tangible and intangible 
assets and rights in connection with the consumer dial-up Internet access 
services operated by the Company in the United States.  In connection with 
the transfer, the parties also entered into a Network Services Agreement 
pursuant to which the Company agreed to service certain of MindSpring's 
individual subscribers through local dial-in POPs connected to the Company's 
network.  As part of these agreements, the Company has the option to transfer 
to MindSpring additional individual subscriber accounts generated in the 
future.

The Company anticipates that the decrease in its individual subscriber 
revenue resulting from consummation of MindSpring agreements will be 
partially offset by revenues from the provision of access services under the 
Network Services Agreement and ongoing revenue from the sales of individual 
subscribers generated in the future, if any, to MindSpring.  Additionally, 
the Company's expenses associated with the individual customer support function 
and depreciation and amortization from certain of the assets transferred are 
expected to decline.

THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1996 AS COMPARED TO THE THREE AND 
NINE MONTHS ENDED SEPTEMBER 30, 1995

RESULTS OF OPERATIONS

   REVENUE. Revenue is derived from the sale of Internet access and related 
services to businesses and individuals and from the sale of connectivity 
software products. Revenue increased by 117.3% from approximately $11.1 
million for the three months ended September 30, 1995 to approximately $24.1 
million for the three months ended September 30, 1996.  Revenue increased by 
149.1% from approximately $24.7 million for the nine months ended September 
30, 1995 to approximately $61.5 million for the nine months ended September 
30, 1996.  The increase in revenue in comparison to the same three and nine 
month periods in 1995 resulted principally from greater sales of Internet 
services to businesses and individuals during 1996.  The Company believes 
these increases were attributable to a number of factors including: an 
increase in the number of subscribers facilitated by an increase in the 
number of POPs in operation; an expansion of the Company's sales force; and 
greater public awareness and acceptance of the Internet. The Company's 
business subscriber base increased by approximately 142.9% from approximately 
6,200 business subscribers at September 30, 1995 to approximately 15,100 
business subscribers at September 30, 1996. The Company had approximately 
40,000 individual subscribers at September 30, 1995.  Under the Company's new 
consumer wholesale strategy, the Company serviced approximately 170,900 
consumer wholesale subscribers at September 30, 1996. Additionally, the 
Company had approximately 11,700 professional subscribers at September 30, 
1996.  The Company's network infrastructure increased from 159 POPs at 
September 30, 1995 to more than 345 POPs at September 30, 1996.  
   



                                      10

<PAGE>

   OTHER INCOME, NET. Other income, net consists of the income, net of 
related asset costs and transfer expenses relating to the transfer to 
MindSpring of substantially all of the Company's individual consumer 
subscribers.  Other income, net was approximately $3.0 million and $5.4 
million for the three and nine months ended September 30, 1996, respectively.
   
   DATA COMMUNICATIONS AND OPERATIONS. Data communications and operations 
costs and expenses consist primarily of leased long distance circuit costs, 
local loop costs, expenses associated with network operations, customer 
support and field service functions and software operations costs and 
expenses. Data communications and operations costs and expenses were 
approximately $9.4 million (84.4% of revenue) and approximately $19.7 million 
(81.6% of revenue) during the three months ended September 30, 1995 and 1996, 
respectively.  Data communications and operations costs and expenses were 
approximately $20.4 million (82.6% of revenue) and approximately $50.2 
million (81.5% of revenue) during the nine months ended September 30, 1995 
and 1996, respectively. The $10.3 million increase for the three months ended 
September 30, 1996 and the $29.8 million increase for the nine months ended 
September 30, 1996 in data communications and operations costs and expenses 
as compared to the same periods in 1995 related principally to increases in 
(i) costs associated with providing dedicated circuits to the Company's 
InterFrame and InterMan subscribers and (ii) circuit costs relating to the 
Company's new POPs deployed through September 1996.  The increase also was 
due, to a lesser extent, to an increase in personnel costs resulting from the 
expansion of the Company's network operations, customer support and field 
service staff concentrated in late 1995 and early 1996, notwithstanding an 
overall decrease in the number of such persons employed by the Company at 
September 30, 1996 due to the transfer of approximately 75 persons to 
MindSpring as of September 1, 1996. Circuit costs relating to the Company's 
new POPs generally are incurred by the Company in advance of anticipated 
expansion in the Company's customer base and consumer wholesale capacity.  
Although the Company expects that data communications and operations costs 
and expenses will continue to increase as the Company's customer base 
continues to grow, it anticipates that such costs and expenses will decrease 
as a percentage of revenue.

   SALES AND MARKETING. Sales and marketing expenses consist primarily of 
sales and marketing personnel costs, advertising costs, fulfillment and 
distribution costs and related occupancy costs. Sales and marketing expenses 
decreased from approximately $7.1 million (63.8% of revenue) during the three 
months ended September 30, 1995 to approximately $6.0 million (24.9% of 
revenue) during the three months ended September 30, 1996. Sales and 
marketing expenses increased from approximately $12.5 million (50.4% of 
revenue) during the nine months ended September 30, 1995 to approximately 
$20.9 million (33.9% of revenue) during the nine months ended September 30, 
1996.  The $8.4 million increase for the nine months ended September 30, 1996 
resulted principally from a significant increase in advertising costs.  The 
$1.1 million decrease for the three months ended September 30, 1996 resulted 
principally from a decrease in advertising costs compared to the same three 
month period in 1995.  All advertising and marketing costs are expensed in 
the period incurred.  The Company expects that, as a result of the 
implementation of its consumer wholesale strategy and its continued efforts 
to focus on businesses, its sales and marketing expenses will decrease as a 
percentage of revenue over time.

   GENERAL AND ADMINISTRATIVE. General and administrative expenses consist 
primarily of salaries and occupancy costs for administrative, executive, 
accounting and finance personnel. General and administrative expenses were 
approximately $2.8 million (25.2% of revenue) during the three months ended 
September 30, 1995 and approximately $5.3 million (22.0% of revenue) during 
the three months ended September 30, 1996. General and administrative 
expenses were approximately $6.4 million (25.8% of revenue) during the nine 
months ended September 30, 1995 and approximately $15.0 million (24.4% of 
revenue) during the nine months ended September 30, 1996.  The Company's 
general and administrative staff increased from 109 at September 30, 1995 to 
120 persons at September 30, 1996. The Company may from time to time adjust 
its general and administrative function in response to current business 
developments.
   
   DEPRECIATION AND AMORTIZATION. Depreciation and amortization expense 
consists principally of expenses associated with the costs of hardware and 
buildout that support expansion and upgrade of the Company's POPs as well as 
the costs of other fixed assets, software costs and other intangible assets. 
Depreciation and amortization costs were approximately $4.9 million (44.1% of 
revenue) 

                                      11
<PAGE>

during the three months ended September 30, 1995 and approximately $8.4 
million (34.7% of revenue) during the three months ended September 30, 1996.  
Depreciation and amortization costs were approximately $8.7 million (35.3% of 
revenue) during the nine months ended September 30, 1995 and approximately 
$21.6 million (35.1% of revenue) during the nine months ended September 30, 
1996. A significant portion of these increases relates to the amortization of 
certain intangible assets recorded in connection with acquisitions completed 
in 1995. In addition, approximately $1.6 million of the amortization for the 
three and nine months ended September 30, 1996 relates to the accelerated 
amortization of software products near the end of their product life cycle.  
POP expansion and existing POP equipment upgrades as well as facility 
expansion required as a result of additional hiring in sales, marketing and 
administration also contributed to this increase. The Company anticipates 
that, based upon its present business plan, its depreciation and amortization 
expense will decrease due to the transfer of certain tangible and intangible 
assets to MindSpring which will be partially offset by increases in 
depreciation as the Company continues to incur capital expenditures 
associated with network infrastructure enhancements.

   INTEREST EXPENSE. Interest expense increased from approximately $0.5 
million for the three months ended September 30, 1995 to approximately $1.4 
million for the three months ended September 30, 1996.  Interest expense 
increased from approximately $1.1 million during the nine months ended 
September 30, 1995 to approximately $3.7 million during the nine months ended 
September 30, 1996.  The increase in interest expense for the three and nine 
months ended September 30, 1996 was principally due to increased borrowings 
and capital lease obligations incurred by the Company to finance network 
expansion and to fund working capital requirements.  The Company may incur 
increased borrowings and capital lease obligations in the near term in 
connection with its network enhancements which would impact the amount of the 
Company's interest expense.

   INTEREST INCOME. Interest income increased from approximately $0.5 million 
for the three months ended September 30, 1995 to approximately $1.2 million 
for the three months ended September 30, 1996. Interest income increased from 
approximately $1.1 million during the nine months ended September 30, 1995 to 
approximately $3.3 million during the nine months ended September 30, 1996.  
The increase in interest income for the three and nine months ended September 
30, 1996 was principally due to the investment of proceeds from the Company's 
public offering in December 1995. These proceeds are currently invested in 
short-term, investment grade, interest bearing securities. 

   OTHER INCOME.  Other income of approximately $2.9 million for the nine 
months ended September 30, 1996 relates to the recognition of realized gains 
on equity securities which were sold by the Company.

   NET LOSS. As a result of the factors discussed above, the Company's net 
loss was approximately $13.1 million and $12.5 million for the three months 
ended September 30, 1995 and 1996, respectively, and approximately $23.4 
million and $38.3 million for the nine months ended September 30, 1995 and 
1996, respectively.  

LIQUIDITY AND CAPITAL RESOURCES

The Company historically has satisfied its cash requirements through cash 
from operations, through borrowings and capital lease financings from 
financial institutions and other third parties and through the issuance of 
equity securities. 

Cash flow used in operating activities was approximately $17.1 million and 
$28.4 million for the nine months ended September 30, 1995 and 1996, 
respectively. Cash flow used in operating activities can vary significantly 
from period to period depending upon the timing of operating cash receipts 
and payments, especially accounts receivable, prepaid expenses and other 
assets, and accounts payable and accrued liabilities. 

Cash flow used in investing activities for the nine months ended September 
30, 1995 and 1996 was approximately $19.0 million and $12.5 million, 
respectively. The expansion of the Company's 



                                     12


<PAGE>

network resulted in capital expenditures of approximately $28.7 million and 
$30.9 million for the nine months ended September 30, 1995 and 1996, 
respectively (which included capital expenditures financed under equipment 
financing agreements aggregating approximately $15.1 million and $30.4 
million during such respective periods).  Additionally, during the nine 
months ended September 30, 1996, the Company invested approximately $14.6 
million in equity and debt securities with original maturities of greater 
than 90 days.

Cash flow provided by financing activities for the nine months ended 
September 30, 1995 was approximately $63.0 million while the cash flow used 
in financing activities for the nine months ended September 30, 1996 was 
approximately $16.1 million. The Company raised approximately $59.6 million 
of equity, net of expenses, in the nine months ended September 30, 1995.  
During the nine months ended September 30, 1996, the Company made repayments 
aggregating $24.6 million on its financing facilities.  Additionally, during 
the nine months ended September 30, 1996, the Company received proceeds from 
the issuance of $6.8 million of notes payable.

As of September 30, 1996, the Company had approximately $45.7 million of cash 
and cash equivalents,  approximately $14.7 million of short-term investments 
and marketable securities and approximately $11.5 million available under 
financing facilities for the future financing of data communications 
equipment and other fixed assets, and a $5.0 million working capital 
facility, subject to availability under a borrowing base formula (at 
September 30, 1996 a maximum availability of approximately $4.1 million), 
under which $2.0 million was outstanding as of September 30, 1996. The 
Company's financing arrangements, which are secured by substantially all of 
the Company's assets, require the Company to satisfy certain financial 
covenants and restrict the payment of dividends.  As of September 30, 1996, 
the Company had commitments to certain telecommunications vendors totaling 
approximately $14.0 million.  The commitments require minimum monthly usage 
levels of data and voice communications over the next five years.  
Additionally, the Company has various agreements to lease office space and 
facilities, and as of September 30, 1996, the Company was obligated to make 
future minimum lease payments of approximately $13.4 million on leases 
expiring in various years through 2005.  In addition, with respect to its 
obligation to purchase an additional 10% interest in World Online B.V. 
("World Online"), the Company may be required to pay cash (not to exceed $5.0 
million) and/or contribute shares of PSINet common stock at the end of 1996.  
Additionally, under its agreement with Chatterjee Management Company, the 
Company expects to contribute up to $5.98 million in cash in exchange for its 
interest in the joint venture.

Based upon its present business plan, the Company believes that working 
capital, funds from operations, existing credit facilities and additional 
borrowings which the Company expects to be able to obtain when needed, will 
be sufficient to meet the presently anticipated working capital and capital 
expenditure requirements of its existing operations.

Securityholder has complied with the provisions of this Article 6; provided,
however, that TCG may transfer any such securities to any of its Affiliates.

    6.2. Right of First Offer.  If a Securityholder (a "Selling
Securityholder") desires to Transfer any or all of its Securities (the "Offered
Securities"), it shall first make a written offer to sell the Offered Securities
(the "Offer") to all Securityholders (other than the Selling Securityholder)
then holding more than 5% of the equity securities of the EJV (a "Significant

Securityholder.

    6.4. Transfer to Third Parties.  If any of the Offered Securities remain
unpurchased following the time periods specified above, the Selling
Securityholder may Transfer such remaining Offered Securities to any third
party; provided, however, that the other Party shall have first consented to the
transfer to such third party, which consent shall not be unreasonably withheld. 
Such transfer shall be made only in strict accordance with the terms set forth
in the Offer and shall be completed within 90 days following the expiration of
the time provided for the purchase of the Offered Securities by the purchasing
Securityholders, after which time any such Transfer shall again become subject
to all the restrictions of this Agreement and the organization documents of the
EJV.  The transferee shall agree in writing to be bound by the terms of this
Agreement.

    6.5. Ineffective Transfers.  No Transfer of any right, title or interest in
any of the Securities shall be effective, and the EJV shall not record or
recognize any such Transfer, until there has been compliance with the provisions

exercise their rights hereunder as to the Offered Securities, and they may do so
at any time, even after the purported Transfer of the Securities.

material breach of a representation under Article 12, such Party had, as of the
date of this Agreement, actual knowledge of such material breach and all

the defense of any such third-party claim with counsel of its own choosing,
subject to approval by the Party seeking indemnification which approval shall
not be unreasonably withheld, and shall be entitled to participate in such
defense with counsel of its own choosing and at its own expense; provided,
however, that control of the defense will remain with counsel for the
indemnifying Party if the indemnifying Party has acknowledged unequivocally in
writing its obligation to indemnify the other Party in regard to the claims to
be defended against.  Failure to give notice as provided herein shall not
relieve the indemnifying Party of its obligations hereunder, except to the
extent that the defense of any claim is prejudiced by such failure to give
notice.  The indemnifying Party shall have the right to compromise or settle for
money damages only any claim giving rise to an obligation for indemnification
hereunder; any claim compromised or settled by the indemnified Party shall not
be subject to indemnification hereunder.

so, the Party suffering such Force Majeure shall notify the other Party in
writing within 14 days after the occurrence of such event of Force Majeure and
shall in every instance, to the extent reasonable and lawful under the
circumstances, use its best efforts to remove or remedy such cause with all
reasonable dispatch.

                 Article 17.   Disclaimer of Agency and Partnership

case, the parties agree to use their best efforts to achieve the purpose of the
invalid provision by a new, legally valid provision.

     If at any time or times after the date hereof until the earlier of (a)

that such registration is in connection with an underwritten public offering; 
provided, further, that, if the underwriter determines that the registration 
of securities in excess of any amount to be registered by the Company would 
adversely affect such offering then the Company may (subject to the 
allocation priority set forth below) exclude 


                                      -3-


<PAGE>

from such registration and underwriting some or all of the Registrable 
Securities which would otherwise be underwritten pursuant to the notice 
described herein.  The Company shall advise all Holders of Registrable 
Securities promptly after such determination by the underwriter, and the 
number of shares of securities that are entitled to be included in the 
registration and underwriting shall be allocated in the following manner:  
the securities to be sold by the Company shall be included in such 
registration and underwriting, and, subject to Section 2.7 hereof, the number 
of additional shares that may be included in the registration and 
underwriting shall be allocated among all Holders of Registrable Securities 
and all holders of other securities having registration rights granted by the 
Company requesting that Registrable Securities or such other securities, as 
the case may be, be included in such registration and underwriting in 
proportion, as nearly as practicable, to their respective holdings of 
Registrable Securities and such other securities.  All expenses of the 
registration and offering and the reasonable fees and expenses of one 
independent counsel for the Holders and all holders of other securities 
having registration rights granted by the Company shall be borne by the 
Company, except that the Holders and all holders of other securities having 
registration rights granted by the Company shall bear underwriting and 
selling discounts and commissions attributable to their Registrable 
Securities or such other securities, as the case may be, being registered and 
transfer taxes on shares being sold by such Holders or other holders, as the 
case may be.  Without in any way limiting the types of registrations to which 
this Section 2.1 shall apply, in the event that the Company shall effect a 
"shelf registration" under Rule 415 of the Securities Act or any other 
similar rule or regulation, the Company shall take all necessary action, 
including, without limitation, the filing of post-effective amendments, to 
permit the Holders to include their shares in such registration in accordance 
with the terms of this Section 2.1. 

SECTION 2.2   REQUIRED REGISTRATIONS

     Prior to September 30, 2006, one or more of the 
Holders may notify the Company in writing that he, she, it or they (i) intend 
to offer or cause to be offered for public sale all or any portion of his, 
her, its or their Registrable Securities having an aggregate proposed 
offering price of not less than $1,000,000 (such requests shall be in writing 
and shall state the number of shares of Registrable Securities to be disposed 
of and the intended method of disposition of such shares by such Holder or 
Holders) and (ii) request that the Company cause such Registrable Securities 
to be registered under the Securities Act; provided, however, that each 
Holder (or transferee of his, her or its Registrable Securities in accordance 
with the terms of this Agreement) may make only two requests for registration 
under this Section 2.2.  Upon receipt of such notification, subject to 
Section 2.7 hereof, the Company will notify all of the Holders of Registrable 
Securities who would be entitled to notice of a proposed registration 




                                      -4-

<PAGE>

under Section 2.1 above of its receipt of such notification.  Upon the 
written request of any such Holder delivered to the Company within 15 days 
after receipt from the Company of such notification, the Company will use its 
best efforts to cause such of the Registrable Securities as may be requested 
by any Holders (including the Holder or Holders giving the initial notice of 
intent to register hereunder) to be registered under the Securities Act 
within 180 days of the notification by the Holders, in accordance with the 
terms of this Section 2.2; PROVIDED, HOWEVER, that unless such registration 
becomes effective, such registration shall not be counted as Athe one request 
for registration that may be made by each Holder (or transferee of his, her 
or its Registrable Securities in accordance with this Agreement) under this 
Section 2.2.  THE COMPANY SHALL, AFTER CONSULTATION WITH THE HOLDERS 
REQUESTING REGISTRATION,The Holders participating in a registration under 
this Section 2.2 shall select one or more underwriters to sell the 
Registrable Securities to be registered through an underwritten public 
offering.    If the underwriter determines that the registration of 
securities in excess of an amount determined by such underwriter would 
adversely affect such offering, then the Company may (subject to the 
allocation priority set forth below) exclude from such registration and 
underwriting some or all of the Registrable Securities which would otherwise 
be underwritten pursuant to this Section 2.2.  The Company shall advise all 
Holders promptly after such determination by the underwriter, and the number 
of shares of securities that are entitled to be included in the registration 
and underwriting shall be allocated in the following manner:  subject to 
Section 2.7 hereof, the number of shares that may be included in the 
registration and underwriting shall be allocated among all Holders of 
Registrable Securities requesting that Registrable Securities be included in 
such registration and underwriting in proportion, as nearly as practicable, 
to their respective holdings of Registrable Securities.  All expenses of such 
registration and offerings and the reasonable fees and expenses of one 
independent counsel for the Holders shall be borne by the Company; PROVIDED, 
HOWEVER, that (i) the Company shall have no liability for such expenses if 
such registration does not become effective due solely to the action or 
failure to act of any Holder requiring such registration and (ii) the Holders 
shall bear underwriting and selling discounts and commissions attributable to 
their Registrable Securities being registered and transfer taxes on shares 
being sold by such Holders.  The Company may postpone the filing of any 
registration statement required hereunder for a reasonable period of time, 
not to exceed 180 days during any 12 month period, if the Company has been 
advised by legal counsel, which counsel shall be acceptable to the Holders, 
that such filing would require the disclosure of a material transaction or 
other matter which would not otherwise be required to be disclosed at such 
time and the Company determines reasonably and in good faith that such 
disclosure would have a material adverse effect on the Company. 
Notwithstanding anything in this Section 2.2 to the contrary, the Company 
shall not be required to effect a registration under this Section 2.2 more 
than 135 days following the end of the Company's fiscal year, if such 
registration shall require the 

                                      -5-

<PAGE>

preparation of audited financial statements 
for any interim period not otherwise prepared by the Company.  If a demand 
registration is requested during such period, the Company will commence such 
registration promptly following the end of the next fiscal year.  If so 
requested by any Holder in connection with a registration under this Section 
2.2, the Company shall take such steps as are required to register such 
Holder's Registrable Securities for sale on a delayed or continuous basis 
under Rule 415 for a period not to exceed 180 days, and also take such steps, 
during such 180-day period, as are required to keep any registration 
effective until all Registrable Securities registered thereunder are sold.  A 
request under this Section 2.2 shall not be counted as a request under 
Section 2.3. 

SECTION 2.3   FORM S-3

     If the Company becomes eligible to use Form S-3 under the Securities Act 
or a comparable successor form, the Company shall use its reasonable best 
efforts to continue to qualify at all times for registration of its capital 
stock on Form S-3 or such successor form.  Each Holder (or transferee of his, 
her or its Registrable Securities in accordance with the terms of this 
Agreement) shall have the right to request and have effected one registration 
of shares of Registrable Securities on Form S-3 or such successor form for a 
public offering of shares of Registrable Securities having an aggregate 
proposed offering price of not less than $1,000,000 (such request shall be in 
writing and shall state the number of shares of Registrable Securities to be 
disposed of and the intended method of disposition of such shares by such 
Holder or Holders).  The Company shall give notice to all of the Holders of 
the receipt of a request for registration pursuant to this Section 2.3 and 
shall provide a reasonable opportunity for such Holders to participate in 
such a registration.  Subject to the foregoing and the provisions of 
applicable law, the Company will use its best efforts to effect promptly the 
registration of all shares of Registrable Securities on Form S-3 or such 
successor form to the extent requested by the Holder or Holders thereof.  The 
Company shall, after consultation with the Holders requesting registration, 
select one or more underwriters to sell the Registrable Securities to be 
registered through an underwritten public offering. All expenses in 
connection with a registration requested pursuant to this Section 2.3 and the 
reasonable fees and expenses of one independent counsel for the Holders shall 
be borne by the Company; PROVIDED, HOWEVER, that (i) the Company shall have 
no liability for such expenses if such registration does not become effective 
due solely to the action or failure to act of any Holder requiring such 
registration and (ii) the Holders shall bear underwriting and selling 
discounts and commissions attributable to their Registrable Securities being 
registered and transfer taxes on shares being sold by such Holders.  The 
Company may postpone the filing of any registration statement required 
hereunder for a reasonable period of time, not to exceed 180 days, if the 
Company has been advised by legal counsel, which counsel shall be acceptable 

                                      -6-


<PAGE>


to the Holders, that such filing would require the disclosure of a material 
transaction or other factor which would not otherwise be required to be 
disclosed at such time and the Company determines reasonably and in good 
faith that such disclosure would have a material adverse effect on the 
Company with respect to the registration of the Registrable Shares.  At the 
Company's option, the Company may elect to include in such registration on 
Form S-3, securities to be issued by the Company and, if required in order to 
effect the registration of such securities, cause the registration to be made 
pursuant to a Registration Statement on Form S-1 or S-2, which shall count as 
the Registration Statement on Form S-3 to be filed pursuant to this Section 
2.3.  In the event that the Company exercises such option, the inclusion of 
shares by Holders will be subject to the right of the underwriters to reduce, 
in view of market conditions, the number of Registrable Securities proposed 
to be registered (in which case the number of shares of Registrable 
Securities to be registered shall be allocated among all Holders in 
proportion, as nearly as practicable, to their respective holdings of 
Registrable Securities); PROVIDED, HOWEVER, that if the number of Registrable 
Securities pursuant to such a registration shall be reduced to a number which 
is less than 60% of the number of Registrable Securities as to which such 
Holders requested registration pursuant to this Section 2.3 then such 
registration shall not be counted as the Registration Statement on Form S-3 
to be filed pursuant to this Section 2.3 by the Holders requesting such 
registration.  Holders of Registrable Securities will not be permitted to 
require the Company to file a Registration Statement pursuant to this Section 
2.3 more frequently than once every six months.  The registration rights 
provided by this Section 2.3 shall expire on September 19, 2006.  If so 
requested by any Holder in connection with a registration under this Section 
2.3, the Company shall take such steps as are required to register such 
Holder's Registrable Securities for sale on a delayed or continuous basis 
under Rule 415 for a period not to exceed 180 days, and also take such steps, 
during such 180-day period, as are required to keep any registration 
effective until all Registrable Securities registered thereunder are sold. 

SECTION 2.4   REGISTRABLE SECURITIES

     For purposes of this Agreement, the term 
"Registrable Securities" shall mean the Common Stock issued pursuant to the 
JVA and any Common Stock issued or issuable with respect thereto by way of a 
stock dividend or stock split or in connection with a combination of shares, 
recapitalization, merger, consolidation or other reorganization. 

SECTION 2.5   FURTHER OBLIGATIONS OF THE COMPANY

     Whenever the Company is required under this Article II to register any 
Registrable Securities, it agrees that it shall also do the following:




                                      -7-


<PAGE>


          (a)  Use its best efforts to diligently prepare and file with the 
Commission a registration statement and such amendments and supplements to 
said registration statement and the prospectus used in connection therewith 
as may be necessary to keep said registration statement effective (but, in 
the case of a registration under this Agreement, for no more than 180 days 
after the initial effective date of the registration statement) and to comply 
with the provisions of the Securities Act with respect to the sale of 
securities covered by said registration statement for the period necessary to 
complete the proposed public offering;

          (b)  Furnish to each selling Holder such copies of each preliminary 
and final prospectus and such other documents as such Holder may reasonably 
request to facilitate the public offering of his or its Registrable 
Securities;

          (c)  Enter into any reasonable underwriting agreement required by 
the proposed underwriter for the selling Holders, if any;

          (d)  Use its best efforts to register or qualify the securities 
covered by said registration statement under the securities or "blue-sky" 
laws of such jurisdiction as any selling Holder may reasonably request, 
provided that the Company shall not be required to register or qualify the 
securities in any jurisdictions which require it to qualify to do business or 
subject itself to taxation or general service of process therein;          

          (e)  Immediately notify each selling Holder, at any time when a 
prospectus relating to his or its Registrable Securities is required to be 
delivered under the Securities Act, of the happening of any event as a result 
of which such prospectus contains an untrue statement of a material fact or 
omits any material fact necessary to make the statements therein not 
misleading, and, at the request of any such selling Holder, prepare a 
supplement or amendment to such prospectus so that, as thereafter delivered 
to the purchasers of such Registrable Securities, such prospectus will not 
contain any untrue statement of a material fact or omit to state any material 
fact necessary to make the statements therein not misleading;

          (f)  Cause all such Registrable Securities to be listed on or 
included in each securities exchange or quotation system (other than PORTAL) 
on which similar securities issued by the Company are then listed;

          (g)  Otherwise use its best efforts to comply with all applicable 
rules and regulations of the Commission and make generally available to its 
security holders, in each case as soon as practicable, but not later than 30 
days after the close of the period covered thereby, an earnings statement of 
the Company which will satisfy the provisions of Section 11(a) of the 
Securities Act;




                                      -8-


<PAGE>


          (h)  Obtain and furnish to each selling Holder, immediately prior 
to the effectiveness of the registration statement (and, in the case of an 
underwritten offering, at the time of delivery of any Registrable Securities 
sold pursuant thereto), a cold comfort letter from the Company's independent 
public accountants in customary form and covering such matters of the type 
customarily covered by cold comfort letters at the holders of a majority of 
the Registrable Securities being sold reasonably request; and

          (i)  Choose the underwriters, auditors, Company legal counsel and 
financial printer to be engaged by the Company in any such registration. 

SECTION 2.6   TRANSFER OF REGISTRATION RIGHTS

     The registration rights of the Holders under this Agreement may be 
transferred to any transferee of at least 500,000 shares (adjusted 
appropriately for stock splits, stock dividends and the like) of Registrable 
Securities in connection with the transfer of at least 80% of the Registrable 
Securities held by the transferor; PROVIDED, HOWEVER, that (i) the 
registration rights may not be transferred to any transferee reasonably 
deemed by a majority of the Board of Directors to be a direct or indirect 
competitor of the Company and (ii) the Company is given written notice at the 
time of or within a reasonable time after such transfer stating the name and 
address of the transferee and identifying the securities with respect to 
which such registration rights are being transferred; PROVIDED, FURTHER, that 
the transferee assumes the obligations of the transferring Holder under this 
Agreement.  Each such transferee shall be deemed to be a "Holder" for 
purposes of this Agreement.  Notwithstanding the foregoing, transfers by any 
Holder to a partner or shareholder of such Holder shall be without 
restriction as to minimum number or percentage of shares. 

SECTION 2.7   PRIOR AND OTHER REGISTRATION RIGHTS AGREEMENTS

     Notwithstanding any provision hereof to the contrary, the provisions of 
this Article II:  (i) shall rank ratably with the registration rights granted 
under the Amended and Restated Registration Rights Agreement (the "Amended 
Registration Rights") and, to the extent the provisions of this Article II 
conflict or are inconsistent with any such Amended Registration Rights, such 
conflict or inconsistency shall be resolved in a manner which, to the 
greatest extent reasonably feasible, affords the Holders and the holders of 
such Amended Registration Rights, the ratable benefits of this Article II and 
such Amended Registration Rights; (ii) shall rank ratably with the 
registration rights granted under the 2/8/95 Registration Rights Agreement 
(the "2/8/95 Registration Rights") and, to the extent the provisions of this 
Article II conflict or are inconsistent with any such 2/8/95 Registration 
Rights, such conflict or inconsistency shall be resolved in a manner which, 
to the greatest extent reasonably feasible, affords the Holders and the 
holders of the 2/8/95 Registration Rights, the ratable benefits of this 
Article II and such 2/8/95 Registration Rights; (iii) shall rank ratably with 
the registration rights granted under the 6/16/95 Registration Rights 
Agreement (the "6/16/95 Registration Rights") and, to the extent the 
provisions of this Article II conflict or are inconsistent with any such 
6/16/95 Registration Rights, such conflict or inconsistency shall be resolved 
in a manner which, to the greatest extent reasonably 

                                      -9-


<PAGE>

feasible, affords the Holders and the holders of the 6/16/95 
Registration Rights, the ratable benefits of this Article II and such 6/16/95 
Registration Rights; (iv) shall rank ratably with the registration rights 
granted under the 7/11/95 Registration Rights Agreement (the "7/11/95 
Registration Rights") and, to the extent the provisions of this Article II 
conflict or are inconsistent with any such 7/11/95 Registration Rights, such 
conflict or inconsistency shall be resolved in a manner which, to the 
greatest extent reasonably feasible, affords the Holders and the holders of 
the 7/11/95 Registration Rights, the ratable benefits of this Article II and 
such 7/11/95 Registration Rights; and (v) shall rank ratably with the 
registration rights to be granted under any other agreement in connection 
with the original issuance of any other capital stock of the Company (the 
"Other Registration Rights") and, to the extent the provisions of this 
Article II shall conflict with any such Other Registration Rights, such 
conflict shall be resolved in a manner which, to the greatest extent 
reasonably feasible, affords the Holders and the holders of such Other 
Registration Rights, the ratable benefits of the provisions of this Article 
II and such Other Registration Rights.                                      


                              ARTICLE III

                    INDEMNIFICATION AND CONTRIBUTION       


SECTION 3.1    INDEMNIFICATION


     Incident to any registration statement referred to in this Agreement, 
and subject to applicable law, the Company will indemnify and hold harmless 
each underwriter, each Holder of Registrable Securities (including its 
respective partners, directors, officers, employees and agents) so 
registered, and each person who controls any of them within the meaning of 
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and 
against any and all losses, claims, damages, expenses and liabilities, joint 
or several (including any investigation, legal and other expenses incurred in 
connection with, and any amount paid in settlement of, any action, suit or 
proceeding or any claim asserted), to which they, or any of them, may become 
subject under the Securities Act, the Exchange Act or other federal or state 
statutory law or regulation, at common law or otherwise, insofar as such 
losses, claims, damages or liabilities arise out of or are based on (i) any 
untrue statement or alleged untrue statement of a material fact contained in 
such registration statement (including any 

                                     -10-


<PAGE>

related preliminary or definitive prospectus, or any amendment or supplement 
to such registration statement or prospectus), (ii) any omission or alleged 
omission to state in such document a material fact required to be stated in 
it or necessary to make the statements in it not misleading, or (iii) any 
violation by the Company of the Securities Act, any state securities or "blue 
sky" laws or any rule or regulation thereunder in connection with such 
registration; PROVIDED, HOWEVER, that the Company will not be liable to the 
extent that such loss, claim, damage, expense or liability (x) arises from 
and is based on an untrue statement or omission or alleged untrue statement 
or omission made in reliance on and in conformity with information furnished 
in writing to the Company by or on behalf of such underwriter, Holder or 
controlling person expressly for use in such registration statement or (y) 
provided that the Company has theretofore timely prepared all necessary 
prospectus supplements or amendments and provided them to the Holder or its 
representative, arises from the failure of any Holder or underwriter to 
comply with such prospectus delivery requirements as are applicable to it.  
With respect to losses, claims, damages, expenses and liabilities arising out 
of or based upon such untrue statement or omission or alleged untrue 
statement or omission in the information furnished in writing to the Company 
by or on behalf of such Holder expressly for use in such registration 
statement or such failure to comply with such prospectus delivery 
requirements, such Holder, severally and not jointly, will indemnify and hold 
harmless each underwriter, the Company (including its directors, officers, 
employees and agents), each other Holder of Registrable Securities (including 
its respective partners, directors, officers, employees and agents) so 
registered, and each person who controls any of them within the meaning of 
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and 
against any and all losses, claims, damages, expenses and liabilities, joint 
or several, to which they, or any of them, may become subject under the 
Securities Act, the Exchange Act or other federal or state statutory law or 
regulation, at common law or otherwise to the same extent provided in the 
immediately preceding sentence.  In no event, however, shall the liability of 
a Holder for indemnification under this Section 3.1 exceed the proceeds 
received by such Holder from its sale of Registrable Securities under such 
registration statement. 

SECTION 3.2   CONTRIBUTION

     If the indemnification provided for in Section 3.1 above for 
any reason is held by a court of competent jurisdiction to be unavailable to 
an indemnified party in respect of any losses, claims, damages, expenses or 
liabilities referred to therein, then each indemnifying party under this 
Article III, in lieu of indemnifying such indemnified party thereunder, shall 
contribute to the amount paid or payable by such indemnified party as a 
result of such losses, claims, damages, expenses or liabilities in such 
proportion as is appropriate to reflect the relative benefits received by the 





                                     -11-



<PAGE>

Company, the other selling Holders and the underwriters from the offering of 
the Registrable Securities as well as the relative fault of the Company, the 
other selling Holders and the underwriters in connection with the statements 
or omissions which resulted in such losses, claims, damages, expenses or 
liabilities, as well as any other relevant equitable considerations.  The 
relative benefits received by the Company, the selling Holders and the 
underwriters shall be deemed to be in the same respective proportions as the 
net proceeds from the offering (before deducting expenses) received by the 
Company and the selling Holders and the underwriting discount received by the 
underwriters, in each case as set forth in the table on the cover page of the 
applicable prospectus, bear to the aggregate public offering price of the 
Registrable Securities.  The relative fault of the Company, the selling 
Holders and the underwriters shall be determined by reference to, among other 
things, whether the untrue or alleged untrue statement of a material fact or 
the omission or alleged omission to state a material fact relates to 
information supplied by the Company, the selling Holders or the underwriters 
and the parties' relative intent, knowledge, access to information and 
opportunity to correct or prevent such statement or omission.  The Company 
and the Holders agree that it would not be just and equitable if contribution 
pursuant to this Section 3.2 were determined by pro rata or per capita 
allocation or by any other method of allocation which does not take account 
of the equitable considerations referred to in this paragraph.  In no event, 
however, shall a Holder be required to contribute any amount under this 
Section 3.2 in excess of the proceeds received by such Holder from its sale 
of Registrable Securities under such registration statement.  No person found 
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) 
of the Securities Act) shall be entitled to contribution from any person who 
was not guilty of such fraudulent misrepresentation.

     SECTION 3.3    EXPENSES, ETC.

          (a)  The amount paid or payable by an indemnified 
party as a result of the losses, claims, damages and liabilities referred to 
in this Article III shall be deemed to include, subject to the limitations 
set forth above, any legal or other expenses reasonably incurred by such 
indemnified party in connection with investigating or defending any such 
action or claim.  The indemnification and contribution provided for in this 
Article III will remain in full force and effect regardless of any 
investigation made by or on behalf of the indemnified parties or any officer, 
director, employee, agent or controlling person of the indemnified parties.   


       (b)  Notwithstanding the foregoing, to the extent that the provisions 
on indemnification and contribution contained in an underwriting agreement 
entered into in connection with any registration statement referred to in 
this Agreement are in 




                                    -12-



<PAGE>

conflict with the foregoing provisions, the provisions in the underwriting 
agreement shall control.                                  

                               ARTICLE IV

                        RULE 144 AND 144A REPORTING      


SECTION 4.1    RULE 144 REPORTING

     With a view to making available the benefits of certain rules and 
regulations of the Commission which may permit the sale of the Registrable 
Securities to the public without registration, the Company agrees to:  (i) at 
all times make and keep public information available as those terms are 
understood and defined in Rule 144 under the Securities Act (and any 
successor rule to Rule 144); (ii) file with the Commission in a timely manner 
all reports and other documents required of the Company under the Securities 
Act and the Exchange Act; and (iii) furnish to each Holder as promptly as 
possible upon its request a written statement by the Company confirming its 
compliance with the reporting requirements of Rule 144 and of the Securities 
Act and the Exchange Act, a copy of the most recent annual or quarterly 
report of the Company, and any other reports and documents so filed as a 
holder may reasonably request in availing itself of any rule or regulation of 
the Commission allowing a holder to sell any such securities without 
registration. 

SECTION 4.2   RULE 144A INFORMATION

     The Company shall, at all times during which it is neither subject to 
the reporting requirements of Section 13 or 15(d) of the Exchange Act, nor 
exempt from reporting pursuant to Rule 12g3-2(b) under the Exchange Act, 
promptly upon the written request of any Holder, provide in writing to such 
Holder and to any prospective transferee of any of Common Stock of such 
Holder the information concerning the Company described in Rule 144A(d)(4) 
under the Securities Act ("Rule 144A Information").  The Company also shall, 
upon the written request of any Holder, cooperate with and assist such Holder 
or any member of the National Association of Securities Dealers, Inc. PORTAL 
system in applying to designate and thereafter maintain the eligibility of 
the Common Stock for trading through PORTAL.  The Company's obligations under 
this Section 4.2 shall at all times be contingent upon receipt from the 
prospective transferees of Common Stock of a written agreement to take all 
reasonable precautions to safeguard the Rule 144A Information from disclosure 
to anyone other than persons who will assist such transferee in evaluating 
the purchase of Common Stock.

hereunder or thereunder shall operate as a waiver of the rights hereof or 
thereof.  No covenant or other provision hereof or thereof may be waived or 
amended other than by a written instrument signed by the party so waiving or 
amending such covenant or other provision.  Any waiver or amendment affected 
in accordance with this Section 5.2 shall be binding upon such Holder and

reporting to the President and CEO.  This is a corporate vice president 
position and as an officer of the Company you must stand for election by the 
Board of Directors each year.  You accept the employment and agree to begin 
work as soon as possible, which we anticipate will be by October 10, 1996; 
and remain in the employ of the Company, and, except during vacation periods

2.  TERM OF EMPLOYMENT. The term of the employment shall commence on the date 
hereof and shall continue for a period of three (3) years.

3.  COMPENSATION:

a)  BASE SALARY.  The Company shall pay you a base salary at the rate of 
$185,000 per annum.  On each of January 1, 1998, and January 1 of 1999 your 
base salary shall be increased at a minimum by an amount equal to 5% of your 
then current base salary.  Your base salary shall be subject to additional 
increases at the discretion of the Company's Board of Directors.  Your base 
salary shall be payable in such installments as the Company regularly pays 
its other salaried employees, subject to such deductions and withholdings as 
may be required by law or by further agreement with you.

b)  PERFORMANCE BONUS.  The Company will pay you a bonus upon the successful 
completion of the objectives established for your performance for the 
applicable year.  The performance criteria will be issued separately by the 
President, at the beginning of each year, and may be changed, with mutual 
fairness, from time to time as situations develop.  The performance bonus for 
the period ending December 31, 1996 will equal ten thousand dollars ($10,000) 
plus a special bonus of up to fifty thousand dollars ($50,000).  Bonuses for 
the years ending December 31, 1997, 1998 and 1999 will be $35,000 at the 
first tier and an additional $25,000 at the second tier, for a  performance 
bonus of not less than $60,000.  Separate criteria will be established for 
your entitlement to each tier's bonus money. The performance bonus may be 
adjusted upward at any time by the Compensation Committee of the Company's 
Board of Directors.  

c)  CAR ALLOWANCE. The Company will provide you with either a company car or 
a car allowance.

d)  INCENTIVE STOCK OPTIONS.  Effective upon the start of your employment, 
the Company shall grant you options to purchase 100,000 shares of the 
Company's common stock (the "Options") pursuant to the Company's Executive 
Stock Incentive Plan, as amended. Such Options shall be evidenced by an 
option agreement in such form as required by the Plan.  Among other terms and 
provisions prescribed by the Plan, the option agreement shall provide that 
(a) the exercise price of the Options shall be the closing price per share of 
the Company's common stock as reported by the NASDAQ Stock Market on the day 
of the start of your employment, (b) the Options shall not be exerciseable 
after the expiration of ten years from the date such Options are granted, and 
(c) the stock shall vest ratably, monthly, over a forty-eight (48) month 
period, provided that for each months' vesting purposes you continue 

<PAGE>

to be employed by the Company or a subsidiary of the Company during such 
month.  

In addition to the terms of the Plan which govern these stock options, in the 
event of a change of control as defined in Section 8(c) below, vesting will 
be accelerated on the number of options necessary so that a total of one half 
of the then outstanding, unvested options will be vested.

4.  EMPLOYEE BENEFITS.  You shall be provided employee benefits, including 
(without limitation) 401(k), 4 weeks paid vacation, and life, health, 
accident and disability insurance under the Company's plans, policies and 
programs available to employees in accordance with the provisions of such 
plans, policies, and programs.

5.  TERMINATION:

a)  Your employment with the Company may be terminated by the Company at any 
time for "Cause" as defined in Section 5(c) hereof. Upon such termination, 
the Company will provide written notice whether it has elected to use the 
non-competition restrictions set forth in Section 6(a) hereof.  Your 
employment may also be terminated by the Company at any time without Cause 
provided the Company shall have given you thirty (30) days' prior written 
notice of such termination.  That written notice must state whether the 
Company has elected to use the non-Competition restriction (which decision 
may not be rescinded).  If you are terminated without cause, you will be paid 
26 weeks of severance, plus a pro-rata bonus and benefits will continue for 
the same period.  In addition, your employment may be terminated by you at 
any time for any reason, provided you shall have given the Company at least 
thirty (30) days' prior written notice of such termination. Termination by  
your resignation does not entitle you to any severance benefits.  By the 30th 
day the Company must notify you in writing whether it has elected to use the 
non-Competition restriction.  Such decision may not be rescinded.  Failure of 
the Company to so notify you shall result in the non-Competition restriction 
not being in place.

b)  Subject to your compliance with your obligations under Section 6 hereof, 
in the event that your employment terminates or is terminated by you or the 
Company for any reason, and the Company has elected to use the 
non-Competition restriction, you shall be entitled, for a period of 
twenty-four (24) months after termination of employment, to the following 
(collectively, the "Termination Payments"):  (i) your then current rate of 
base salary as provided in Section 3;  (ii) all life insurance and health 
benefits, disability insurance and benefits and reimbursement theretofore 
being provided to you;  and (iii) Company contributions, to the extent 
permitted by applicable law, to a SEP-IRA, Keogh or other retirement 
mechanism selected by you sufficient to provide the same level of retirement 
benefits you would have received if 


<PAGE>

you had remained employed by the Company during such 24-month period.  The 
Company shall make up the difference in cash payments directly to you to the 
extent that applicable law would not permit it to make such contributions. 

c)  The Company shall have "Cause" for your termination of your employment by 
reason of any breach of your agreement not to compete pursuant to Section 6 
hereof, your committing an act materially adversely affecting the Company 
which constitutes reckless conduct or wanton or willful misconduct, your 
conviction of a felony,  or any material breach by you of this Agreement.

6.  AGREEMENT NOT TO COMPETE.

a)  In consideration of your employment pursuant to this Agreement and for 
other good and valuable consideration, the receipt and adequacy of which is 
hereby acknowledged, you covenant to and agree with the Company that, so long 
as you are employed by the Company under this Agreement and for a period of 
twenty-four (24) months following the termination of such employment (but 
only if the Company has elected to enforce the restriction), you shall not, 
without the prior written consent of the Company, either for yourself or for 
any other person, firm or corporation, manage, operate, control, participate 
in the management, operation or control of or be employed by any other person 
or entity which is engaged in providing Internet-related network or 
communications services competitive with the Internet-related network or 
communication services offered to customers by the Company as of the date of 
termination or within six (6) months thereafter.  The foregoing shall in no 
event restrict you from:  (i) writing or teaching, whether on behalf of 
for-profit, or not-for-profit institution(s);  (ii) investing (without 
participating in management or operation) in the securities of any private or 
publicly traded corporation or entity; or (iii) after termination of 
employment, becoming employed by a hardware, software or other vendor to the 
Company, provided that such vendor does not offer network or communication 
services that are competitive with the Internet-related network or 
communications services offered by the Company as of the date of termination 
of employment or within six (6) months thereafter.

b)  You may request permission from the Company's Board of Director's to 
engage in activities which would otherwise be prohibited by Section 6(a).  
The Company shall respond to such request within thirty (30) days after 
receipt.  The Company will notify you in writing if it becomes aware of any 
breach or threatened breach of any of the provisions in Section 6(a), and you 
shall have thirty (30) days after receipt of such notice in which to cure or 
prevent the breach, to the extent that you are able to do so.  You and the 
Company acknowledge that any breach or threatened breach by you of any of the 
provisions in Section 6(a) above cannot be remedied by the recovery of 


<PAGE>

damages, and agree that in the event of any such breach or threatened breach 
which is not cured with such 30-day period, the Company may pursue injunctive 
relief for any such breach or threatened breach.  If a court of competent 
jurisdiction determines that you breached any of such provisions, you shall 
not be entitled to any Termination Payments from and after date of the 
breach.  In such event, you shall promptly repay any Termination Payments 
previously made plus interest thereon from the date of such payment(s) at 12% 
per annum.  If, however, the Company has suspended making such Termination 
Payments and a court of competent jurisdiction finally determines that you 
did not breach such provision or determines such provision to be 
unenforceable as applied to your conduct, you shall be entitled to receive 
any suspended Termination Payment, plus interest thereon from the date when 
due at 12% per annum.  The Company may elect (once) to continue paying the 
Termination Payments before a final decision has been made by the court.

7.  INTELLECTUAL PROPERTY   Ownership of Work Product.  All copyrights, 
patents, trade secrets, or other intellectual property rights associated with 
any ideas, concepts, techniques, inventions, processes, or works of 
authorship developed or created by you during the course of performing the 
Company's work (collectively the "Work Product") shall belong exclusively to 
the Company and shall, to the extent possible, be considered a work made for 
hire for the Company within the meaning of Title 17 of the United States 
Code.  You automatically assign, and shall assign at the time of creation of 
the Work Product, without any requirement of further consideration, any 
right, title, or interest you may have in such Work Product, including any 
copyrights or other intellectual property rights pertaining thereto.  Upon 
request of the Company, you shall take such further actions, including 
execution and delivery of instruments of conveyance, as may be appropriate to 
give full and proper effect to such assignment.

8.  TRANSFERABILITY.

a)  As used in this Agreement, the term "Company" shall include any successor 
to all or part of the business or assets of the Company who shall assume and 
agree to perform this Agreement.  In the event of a Change of Control, (as 
defined in Section 8(c) below), this agreement shall terminate.  This 
Agreement shall inure to the benefit of and be enforceable by you and your 
personal or legal representatives, executors, administrators, heirs, 
distributees, devisees and legatees.

b)  Except as provided under paragraph (a) of this Section 8, neither this 
Agreement nor any of the rights or obligations hereunder shall be assigned or 
delegated by any party hereto without the prior written consent of the other 
party.


<PAGE>

c)  As used in this Agreement, "Change in Control" shall mean:  (i) the 
shareholders of the Company approve an agreement for the sale of all or 
substantially all of the assets of the Company;  or (ii) the shareholders of 
the Company approve a merger or consolidation of the Company with any other 
corporation (and the Company implements it), other than (A) a merger or 
consolidation which would result in the voting securities of the Company 
outstanding immediately prior thereto continuing to represent more than 80% 
of the combined voting power of the voting securities of the Company, or such 
surviving entity, outstanding immediately after such merger or consolidation, 
or (B) a merger or consolidation effected to implement a recapitalization of 
the Company (or similar transaction) in which no "person" (as defined below) 
acquires more than 30% of the combined voting power of the Company's 
then-outstanding securities;  or (iii) any "person," as such term is used in 
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended 
(the "Exchange Act") (other than (A) the Company, (B) any corporation owned, 
directly or indirectly, by the Company or the shareholders of the Company in 
substantially the same proportions as their ownership of stock of the Company 
is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the 
Exchange Act), directly or indirectly, of securities of the Company 
representing 30% or more of the combined voting power of the Company's then 
outstanding securities.  

9.  SEVERABILITY.  The invalidity or unenforceability of any particular 
provision of this Agreement shall not affect the other provisions hereof, and 
this Agreement shall be construed in all respects as if such invalid or 
unenforceable provision were omitted.  If a court of competent jurisdiction 
determines that any particular provision of this Agreement is invalid or 
unenforceable, the court shall restrict the provision so as to be 
enforceable.  However, if the provisions of Section 6 shall be restricted, a 
proportional reduction shall be made in the payments under Section 5b.

10. ENTIRE AGREEMENT;   WAIVERS.  This letter Agreement contains the entire 
agreement of the parties concerning the subject matter hereof and supersedes 
and cancels all prior agreements, negotiations, correspondence, undertakings 
and communications of the parties, oral or written.  No waiver or 
modification of any provision of this Agreement shall be effective unless in 
writing and signed by both parties.

11. NOTICES.  Any notices, requests, instruction or other document to be 
given hereunder shall be in writing and shall be sent certified mail, return 
receipt requested, addressed to the party intended to be notified at the 
address of such party as set for at the head of this agreement or such other 
address as such party may designate in writing to the other.

12. GOVERNING LAW. THIS LETTER AGREEMENT SHALL BE SUBJECT TO, 
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH

non-competition restrictions set forth in Section 5(a) hereof.  Your 
employment may also be terminated by the Company at any time without Cause 
provided the Company shall have given you thirty (30) days' prior written 
notice of such termination.  That written notice must state whether the

within the initial one year term of your employment, you will be paid ninety 
(90) days' severance pay.  In addition, your employment may be terminated by 
you at any time for any reason, provided you shall have given the Company at

30th day the Company must notify you in writing whether it has elected to use

twelve (12) months after termination of employment, to the following 
(collectively, the "Termination Payments"):  (i) your then current rate of 
base salary as provided in Section 2;  (ii) all life insurance and health 
benefits, disability insurance and benefits and reimbursement theretofore

cash payments directly to you to the extent that applicable law would not 
permit it to make such contributions.

5.  AGREEMENT NOT TO COMPETE.


<PAGE>

a)  In consideration of your employment pursuant to this Agreement and for 
other good and valuable consideration, the receipt and adequacy of which is 
hereby acknowledged, you covenant to and agree with the Company that, so long 
as you are employed by the Company under this Agreement and for a period of 
twelve (12) months following the termination of such employment (but only if 
the Company has elected to enforce the restriction), you shall not, without 
the prior written consent of the Company, either for yourself or for any 
other person, firm or corporation, manage, operate, control, participate in 
the management, operation or control of or be employed by any other person or 
entity which is engaged in providing Internet-related network or 
communications services competitive with the Internet-related network or 
communication services offered to customers by the Company as of the date of 
termination or within six (6) months thereafter.  The foregoing shall in no 
event restrict you from:  (i) writing or teaching, whether on behalf of 
for-profit, or not-for-profit institution(s);  (ii) investing (without 
participating in management or operation) in the securities of any private or 
publicly traded corporation or entity; or (iii) after termination of 
employment, becoming employed by a hardware, software or other vendor to the 
Company, provided that such vendor does not offer network or communication 
services that are competitive with the Internet-related network or 
communications services offered by the Company as of the date of termination 
of employment or within six (6) months thereafter.

b)  You may request permission from the Company's Board of Director's to 
engage in activities which would otherwise be prohibited by Section 5(a).  
The Company shall respond to such request within thirty (30) days after 
receipt.  The Company will notify you in writing if it becomes aware of any 
breach or threatened breach of any of the provisions in Section 5(a), and you 
shall have thirty (30) days after receipt of such notice in which to cure or 
prevent the breach, to the extent that you are able to do so.  You and the 
Company acknowledge that any breach or threatened breach by you of any of the 
provisions in Section 5(a) above cannot be remedied by the recovery of 
damages, and agree that in the event of any such breach or threatened breach 
which is not cured with such 30-day period, the Company may pursue injunctive 
relief for any such breach or threatened breach.  If a court of competent 
jurisdiction determines that you breached any of such provisions, you shall 
not be entitled to any Termination Payments from and after date of the 
breach.  In such event, you shall promptly repay any Termination Payments 
previously made plus interest thereon from the date of such payment(s) at 12% 
per annum.  If, however, the Company has suspended making such Termination 
Payments and a court of competent jurisdiction finally determines that you 
did not breach such provision or determines such provision to be 
unenforceable as applied to your conduct, you shall be entitled to receive 
any suspended Termination Payment, plus interest thereon from the date when 
due at 12% per annum.  The Company may elect (once) to 

<PAGE>

continue paying the Termination Payments before a final decision has been 
made by the court.

patents, trade secrets, or other intellectual property rights associated with 
any ideas, concepts, techniques, inventions, processes, or works of 
authorship developed or created by you during the course of performing the

give full and proper effect to such assignment.

to all or part of the business or assets of the Company who shall assume and 
agree to perform this Agreement. 

This Agreement shall inure to the benefit of and be enforceable by you and your
personal or legal representatives, executors, administrators, heirs,
distributees, devisees and legatees.

delegated by any party hereto without the prior written consent of the other 
party.

c)  As used in this Agreement, "Change in Control" shall mean:  (i) the

MASTER SOFTWARE/EQUIPMENT LEASE AGREEMENT ("Agreement") dated as of September 
20, 1996 between LPI SOFTWARE FUNDING GROUP, INC., One Glenhardie Corporate 
Center, 1275 Drummers Lane, Wayne, PA  19087 ("Lessor") and PSINet, Inc., 510 
Huntmar Park Drive, Herndon, VA 22070 ("Lessee").


1.  LEASE 
    -----

    This Agreement specifies the general terms and conditions which 
    apply to each separate lease transaction, including renewals, between 
    Lessor and Lessee.  Each Lease ("Lease") will be a separate Lease of 
    the software and documentation ("Software") and equipment ("Equipment") 
    specified in the Lease, will substantially be in the form attached as 
    Exhibit A, will incorporate by reference all provisions of this 
    Agreement, and may specify additional provisions. 
    
    In return for Lessor paying the Software License fee and Equipment cost 
    so that the Lessee may acquire the right to use the Software and the 
    Equipment, Lessee shall pay all Lease Payments to Lessor, as well as 
    comply with all other terms and conditions of this Agreement.  A Lease 
    shall be binding upon Lessor and Lessee from the date of acceptance and 
    execution by Lessor at its office in Pennsylvania. 
    
    Software does not include any intellectual property rights vested in 
    the Software Licensor or developer.

2.  TERM 
    ----

    The term of this Agreement shall commence on the date set forth 
    above and shall continue in effect as long as any Lease remains in 
    effect.  The term of each Lease shall commence on the date the Software 
    and Equipment is accepted by Lessee, as evidenced in the Certificate of 
    Acceptance ("Commencement Date"), and shall continue for the full 
    number of periods specified in such Lease ("Initial Term") after the 
    first day of the month following the Commencement Date. 

3.  LEASE PAYMENT 
    -------------

    Lessee shall for each period pay to Lessor, without notice or 
    demand, at the office of Lessor in Wayne, Pennsylvania, or at such 
    other place as Lessor may designate, the amount specified as Lease 
    Payment in the Lease plus applicable state and local sales or use 
    taxes.  Lessee's obligation to pay shall begin on the Commencement 
    Date.  Lease Payment is due in advance on the first day of each period. 
    
    When the Commencement Date is not on the first day of a month, an 
    interim Lease Payment, at the daily amount equal to Lease Payment times 
    the number of periods per year divided by 360, from and including the 
    Commencement Date to the end of the month, shall be due and payable 
    upon Lessee's receipt of an invoice from Lessor. 

4.  SECURITY INTEREST 
    -----------------

    Lessee grants to Lessor a security interest in the Software, the 
    Software License, the Software License Agreement, all other rights 
    acquired by Lessee from the Software Licensor relating to the Software, 
    and the Equipment, together with all options, accessories, accessions, 
    and replacements to the Equipment and all proceeds thereof, including 
    insurance proceeds, and all general intangibles related thereto 
    ("Collateral").  The security interest granted by Lessee includes any 
    upgrades, new releases or new versions of the Collateral.

                                                                        Page 1
<PAGE>

5.  LEASE NOT CANCELLABLE; LESSEE'S OBLIGATIONS ABSOLUTE 
    ----------------------------------------------------

    Lessee's obligation to pay shall be absolute and unconditional and 
    shall not be subject to any delay, reduction, set-off, defense, 
    counterclaim or recoupment for any reason whatsoever, including any 
    failure of the Software or Equipment.  If the Software or Equipment is 
    unsatisfactory for any reason, Lessee shall make any claim solely 
    against Software Licensor and Equipment manufacturer or vendor and 
    shall, nevertheless, pay Lessor all amounts payable under the Lease. 
    
6.  TITLE 
    -----

    (a) SOFTWARE.  No title or right in the Software or Software 
    License shall pass to the Lessee by virtue of this Agreement.  All 
    upgrades, new releases or new versions of the Software acquired by 
    Lessee shall immediately become subject to the Lease.

    (b) EQUIPMENT.  The Equipment is and shall remain the property of 
    Lessor. Lessee shall have no right, title or interest in the Equipment, 
    except as set forth in the Lease. The Equipment is and shall remain 
    personal property and shall not become a fixture or realty. Lessee 
    shall affix to the Equipment any labels supplied by Lessor indicating 
    Lessor as the owner.
    
7.  SELECTION AND USE OF SOFTWARE 
    -----------------------------

    Lessee shall be responsible for selection, use, and results 
    obtained from the Software and Equipment and acknowledges that Lessor 
    is not a developer of, dealer in, or licensor of, the Software and that 
    Lessor is not a manufacturer of or dealer in the Equipment.  Lessee 
    authorizes Lessor to insert in each Lease the identifying data of the 
    Software and Equipment. 

8.  ASSIGNMENT OF WARRANTIES 
    ------------------------

    Lessor assigns to Lessee, to the extent assignable, for the term of 
    this Lease, any warranty applicable to the Software and Equipment, and 
    authorizes Lessee to obtain the customary service and support furnished 
    by Software Licensor and Equipment manufacturer or vendor at Lessee's 
    expense.  

9.  DISCLAIMER OF REPRESENTATIONS AND WARRANTIES BY LESSOR 
    ------------------------------------------------------

    LESSOR MAKES NO REPRESENTATION OR WARRANTY, DIRECT OR INDIRECT, 
    EXPRESS OR IMPLIED, WITH RESPECT TO THE SOFTWARE AND EQUIPMENT, 
    INCLUDING THOSE OF THE DURABILITY, SUITABILITY, MERCHANTABILITY, 
    FITNESS FOR PARTICULAR PURPOSE, CONDITION, OR DESIGN.  AS TO LESSOR, 
    LESSEE LEASES THE SOFTWARE AND EQUIPMENT "AS IS".  LESSEE WAIVES ALL 
    RIGHT TO MAKE ANY CLAIM AGAINST LESSOR FOR BREACH OF ANY WARRANTY OF 
    ANY KIND WHATSOEVER.  
    
    LESSOR SHALL NOT BE LIABLE TO LESSEE FOR ANY LOSS, DAMAGE OR 
    EXPENSE OF ANY KIND CAUSED BY OR RELATED TO, DIRECTLY, INDIRECTLY OR 
    CONSEQUEN-TIALLY, THE SOFTWARE AND EQUIPMENT OR FOR ANY CONSEQUENTIAL 
    DAMAGES, ANY LOSS OF PROFITS OR SAVINGS, LOSS OF USE, OR ANY OTHER 
    COMMERCIAL LOSS. 

10. POSSESSION, USE AND OPERATION OF SOFTWARE AND EQUIPMENT 
    -------------------------------------------------------

    (a) DELIVERY AND INSTALLATION.  Lessee shall arrange and pay for
    the delivery and installation of the Software and Equipment. 

    (b) USE AND MAINTENANCE.  Lessee shall use the Software and 
    Equipment in a good and careful manner and in compliance with all 
    operating instructions, laws and regulations and the Software License 
    Agreement. 

                                                                        Page 2

<PAGE>

    (c) ALTERATIONS AND ATTACHMENTS.  Lessee may make alterations, 
    modifications or attachments to the Software and Equipment so long as 
    not in violation of the Software License Agreement.  Any alterations, 
    unless consented to by the Software Licensor, shall not be made to the 
    original Software, but only to a copy.  All alterations, modifications 
    and attachments to the Equipment which cannot be readily removed 
    without damaging the function, use or economic value of the Equipment 
    shall immediately become a part of the Equipment and property of the 
    Lessor.

    (d) SUBLEASE AND RELOCATION. LESSEE MAY NOT SUBLEASE THE SOFTWARE 
    AND EQUIPMENT OR RELOCATE SUCH ITEMS FROM THE STATE IN WHICH THEY WERE 
    INSTALLED, UNLESS CONSENTED TO BY LESSOR.

    (e) ASSIGNMENT BY LESSEE. LESSEE SHALL NOT ASSIGN, TRANSFER OR 
    OTHERWISE DISPOSE OF THE LEASE OR COLLATERAL, OR ANY INTEREST THEREIN, 
    OR CREATE OR PERMIT ANY LIEN OR ENCUMBRANCE THEREON, EXCEPT THOSE 
    CREATED BY LESSOR. LESSEE ACKNOWLEDGES THAT ANY ASSIGNMENT BY LESSEE 
    WOULD MATERIALLY INCREASE THE RISK TO LESSOR.

    (f) INSPECTION.  Lessee shall make the Software, Equipment and any 
    maintenance records available for inspection by Lessor during Lessee's 
    normal business hours. 

11. TAXES AND FEES 
    -------------- 

    Lessee shall pay when due, or reimburse (including taxes on any 
    reimbursement) and indemnify and hold Lessor harmless from and against, 
    all taxes, fees, assessments or other charges of any nature whatsoever 
    (except for any taxes based upon Lessor's net income, unless such net 
    income taxes are in substitution for or release Lessee from any taxes 
    which Lessee would otherwise be obligated to pay under this Section), 
    which may be imposed by any taxing jurisdiction upon or relating to the 
    Software and Equipment.  If Lessee determines that any item of Software 
    or Equipment is not taxable, Lessee shall, prior to the date of 
    commencement of any Lease, provide Lessor with written notice of such 
    determination and the basis for such determination. Should any taxing 
    jurisdiction challenge such determination, Lessee shall indemnify 
    Lessor for all costs (including interest, penalties and attorneys' 
    fees) associated with defending Lessee's determination.  Lessee shall 
    file personal property tax returns including all items of Software or 
    Equipment which may be taxable and pay any taxes which may be due 
    rather than waiting for Lessor to file and pay such taxes and then 
    invoice Lessee for reimbursement.
    
12. END OF LEASE - $0 TERMINATION OPTION AMOUNT
    -------------------------------------------

    Provided an Event of Default has not occurred, the Lease has not 
    been terminated, and all Lessee's obligations under the Lease have been 
    satisfied, all Lessor's right, title and interest in the Software and 
    Equipment shall automatically revert to Lessee at the expiration of the 
    Initial Term of the lease.

13. END OF LEASE - GREATER THAN $0 TERMINATION OPTION AMOUNT
    --------------------------------------------------------

    Provided an Event of Default has not occurred, the Lease has not 
    been terminated, and Lessee desires to retain possession of the 
    Software and Equipment, Lessee shall have the option at the expiration 
    of the Lease upon no less than 60 days' and no more than 120 days' 
    prior irrevocable written notice to Lessor: (a) to retain the Equipment 
    and original and all backup copies of the Software upon payment of the 
    Termination Option Amount specified in the Lease, payment of which 
    shall automatically terminate the Lease, or (b) to extend the Lease for 
    12 months at a monthly Lease Payment equal to the Termination Lease 
    Percentage specified in the Lease multiplied by the Software License 
    Fee and Equipment cost.
    
    If the retention or extension options are not exercised, Lessee 
    shall, pursuant to Lessor's instructions and at Lessee's sole expense, 
    return the Equipment and the original and all backup copies of the 
    Software, including documentation, to Lessor in the same operating 
    order as when received, except for normal wear and tear.  Lessee shall 
    return the Software and Equipment to a location in the continental 
    United States specified by Lessor.
    
    If the retention or extension options are not exercised and the 
    Software and Equipment are not returned, the Lease shall be renewed for 
    one period at a time until the Software and Equipment are returned to 
    Lessor and Lessee shall continue to pay Lease Payments in the original 
    amount set forth in the Lease. 

                                                                        Page 3

<PAGE>

14. EARLY TERMINATION OPTION
    ------------------------

    Provided an Event of Default has not occurred, upon no less than 30 
    days' and no more than 90 days' prior irrevocable written notice to 
    Lessor, Lessee may as of any Lease Payment Date, terminate the Lease 
    upon payment to Lessor an amount equal to (1) the total Lease Payment 
    and other sums due and unpaid under the Lease at the date of payment 
    and (2) Stipulated Loss Value set forth in Exhibit B as of the date of 
    payment.
    

15. RISK OF LOSS 
    ------------

    Lessee shall bear the entire risk of loss, theft, destruction and 
    damage to the Software and Equipment ("Event of Loss") after the 
    Commencement Date.  If an Event of Loss shall occur, Lessee shall 
    immediately notify Lessor and, at the option of Lessor, shall promptly, 
    at Lessee's sole cost:
    (a) place the Software and Equipment in good condition, repair and 
    working order.
    (b) replace the Software and Equipment with like Software and Equipment 
    and grant to Lessor all rights in such Software and Equipment and 
    related Collateral. 

    Lessee appoints Lessor as Lessee's attorney-in-fact to make claim 
    for, receive payment of, and execute and endorse all documents, checks 
    or drafts issued with respect to such loss or damage under any 
    insurance policy relating thereto. 

    If and when Lessor shall have received any insurance proceeds on 
    account of an Event of Loss, and if Lessor, in its reasonable judgment, 
    shall be satisfied that Lessee has properly performed the obligations 
    undertaken by this section, Lessor shall pay over to Lessee out of such 
    proceeds the actual amounts expended by Lessee under Section 15 (a) or (b). 
    
16. INSURANCE 
    ---------

    Lessee shall, at its own expense, obtain on the Software and 
    Equipment all risk property damage insurance in such amounts, against 
    such risks, in such form and with such insurers as shall be reasonably 
    satisfactory to Lessor.  The amount of property damage insurance shall 
    not be less than Stipulated Loss Value. Each insurance policy shall 
    name Lessee as an insured and Lessor and its assignees as an additional 
    insured and loss payee and shall contain a clause requiring the insurer 
    to give Lessor at least 30 days' prior written notice of any alteration 
    or cancellation of such policies. Lessee shall furnish to Lessor a 
    certificate of insurance or other evidence satisfactory to Lessor that 
    such insurance coverage is in effect, provided, however, that Lessor 
    shall be under no duty either to ascertain the existence of or to 
    examine such insurance or to advise Lessee in the event such insurance 
    shall not comply with the requirements hereof. 
    
17. GENERAL INDEMNITY 
    -----------------

    Lessee shall defend, indemnify and hold Lessor, any assignee and 
    any secured party harmless from and against all claims (including 
    claims based on negligence, tort and strict liability ("Claims")), 
    costs, including reasonable attorney's fees, damages and liabilities 
    arising out of or related to the ownership, selection, possession, 
    leasing, renting, operation, control, use, maintenance, delivery, 
    return or other disposition of the Software and Equipment and/or the 
    Collateral or by operation of law, excluding any Claims which result 
    from the gross negligence or willful misconduct of Lessor. 
    
    Lessor may, at its option and at its sole expense, participate in 
    any such action with counsel of its own choice.  Lessee agrees that it 
    shall not settle or compromise any claim, action or proceeding without 
    first obtaining Lessor's prior written consent. 
    
18. REPRESENTATIONS AND WARRANTIES OF LESSEE 
    ---------------------------------------- 

    Lessee represents, warrants and covenants, with the execution of 
    each Lease that, with respect to this Agreement and each Lease:
    (a) this Agreement and each Lease constitute legal, valid and binding 
    agreements of Lessee enforceable in accordance with their respective 
    terms;
    (b) all financial statements furnished to Lessor are true and 
    correct in all material respects and Lessee shall furnish Lessor with 
    its annual independently reviewed financial statements

                                                                        Page 4

<PAGE>

    and such other financial information as Lessor may reasonably request; and
    (c) the Equipment is personal property and will not become a fixture 
    under applicable law.
    (d) that Lessee is the Licensee of the Software under the Software 
    License Agreement. 
    
19. ASSIGNMENT/TRANSFER BY LESSOR
    -----------------------------

    LESSOR MAY SELL OR OTHERWISE TRANSFER ITS INTEREST IN THE LEASE AND 
    THE COLLATERAL IN WHOLE OR IN PART.  LESSEE CONSENTS TO SUCH TRANSFER 
    AND, IF LESSEE IS GIVEN WRITTEN NOTICE OF ANY TRANSFER, IT SHALL 
    PROMPTLY ACKNOWLEDGE RECEIPT IN WRITING. LESSEE ACKNOWLEDGES THAT ANY 
    ASSIGNMENT BY LESSOR WILL NOT MATERIALLY CHANGE THE DUTY OF THE LESSEE. 
    LESSEE SHALL NOT ASSERT AGAINST ANY TRANSFEREE ANY SET-OFF, DEFENSE OR 
    COUNTERCLAIM THAT LESSEE MAY HAVE AGAINST LESSOR (INCLUDING ANY DEFENSE 
    ARISING OUT OF THE INSOLVENCY OR BANKRUPTCY OF LESSOR) OR ANY OTHER 
    PERSON AND UPON NOTICE FROM LESSOR SHALL PAY THE LEASE PAYMENT AND ANY 
    OTHER AMOUNTS DUE UNDER THE LEASE AS DIRECTED. 

    LESSOR'S TRANSFEREE SHALL BE ENTITLED TO ENFORCE THE RIGHTS SO 
    TRANSFERRED, BUT SHALL BE UNDER NO LIABILITY TO LESSEE TO PERFORM ANY 
    OF THE OBLIGATIONS OF LESSOR, THE SOLE REMEDY OF LESSEE BEING AGAINST 
    LESSOR.  LESSOR SHALL NOT BE RELIEVED OF ITS OBLIGATIONS HEREUNDER, 
    EXCEPT AS SPECIFICALLY PROVIDED. 
    
20. LATE PAYMENTS 
    -------------

    If any amount to be paid to Lessor is not received within 5 days 
    after its due date, Lessee shall pay Lessor on demand a late charge of 
    1.5% (or the maximum allowed by law, whichever is less) of such payment 
    for each month, or any part thereof, that the payment is not received. 

21. DEFAULT; NO WAIVER 
    ------------------

    Lessee shall be in default under the Lease upon the occurrence of 
    any of the following event ("Events of Default"):  
    (a) Lessee fails to pay any amount required to be paid under the 
    Lease within 5 days after the due date; 
    (b) Lessee fails to perform any other provisions under the Lease, or any
    other Lease incorporating this Agreement, and such failure shall continue 
    unremedied for a period of 10 days after written notice from Lessor; 
    (c) Any representation or warranty made by Lessee in the Lease or 
    related documents is inaccurate in any material respect; 
    (d) Lessee makes an assignment for the benefit of creditors, consents to 
    the appointment of a trustee or receiver, or if either shall be appointed 
    for Lessee or for a substantial part of its property without its consent; 
    (e) any petition or proceeding is filed by or against Lessee under 
    any Federal or state bankruptcy or insolvency code or similar law; 
    (f) if applicable, Lessee makes a bulk transfer subject to the 
    provisions of the Uniform Commercial Code; 
    (g) Lessee shall default under any other agreement with Lessor or 
    Fleet Bank, N.A. or their successors or assigns; or 
    (h) Lessee suffers an adverse material change in its financial 
    condition from the Commencement Date and Lessor, acting in good faith, 
    deems itself or any of its Collateral to be insecure. 

    Any failure of Lessor to require strict performance by Lessee or any waiver
    by Lessor of any provision in the Lease shall not be construed as a consent
    or waiver of any other breach of the same or of any other provision. 

22. REMEDIES 
    --------

    Upon the occurrence of an Event of Default, Lessor may, in its sole 
    discretion, do any one or more of the following: 
    (a) proceed by appropriate court action to enforce performance by Lessee 
    of the terms of the Lease, or recover from Lessee all damages or expenses,
    including reasonable attorneys' fees, arising from the Event of Default; 
    (b) declare the Lease to be in default; 

                                                                        Page 5

<PAGE>

    (c) terminate the Lease in whole or in part; 
    (d) recover from Lessee all amounts then due and as liquidated 
    damages the Stipulated Loss Value which would have been due on the 
    occurrence of the exercise by Lessee of its Early Termination Option; 
    (e) take possession of and remove Equipment and the original and 
    all backup copies of the Software, wherever located, without demand or 
    notice, without any court order or other process of law, without 
    liability to Lessor or its agents for entry, damage to property or 
    otherwise, except for gross negligence or willful misconduct; 
    (f) demand that Lessee return any or all items of Software and 
    Equipment to Lessor in accordance with Section 13 and, for each day 
    that Lessee fails to return any item of Software and Equipment, Lessor 
    may demand an amount equal to the Lease Payment prorated on the basis 
    of a 30-day month, in effect immediately prior to such default; and
    (g) upon demand by Lessor, Lessee shall immediately cease using the 
    Software and Equipment and remove such Software from any computer on 
    which it is installed. 

    Lessor shall, to the extent permitted by law or any agreement 
    pertaining to the Collateral, sell, lease or otherwise dispose of all 
    or any portion of the repossessed or recovered Collateral in a 
    commercially reasonable manner, with or without notice and on public or 
    private bid.  The cash proceeds from any sale or other disposition, or, 
    if the Collateral is leased, the present value, discounted at 3%, of 
    the Lease Payments due under any replacement lease for a term not to 
    exceed the expiration of the lease or renewal lease (all such amounts 
    being referred to as "Proceeds") shall be retained by Lessor.  If the 
    net proceeds (Proceeds less all costs and expenses, including 
    reasonable attorney's fees, incurred in connection with the recovery, 
    repair or disposition of the Software and Equipment) shall be less than 
    the amount Lessee owes to Lessor, Lessee shall be liable for such 
    deficiency.  Lessor may pursue any other remedy available at law or in 
    equity, including seeking damages, specific performance and injunctive 
    relief. 
    
    No right or remedy is exclusive of any other or permitted by law or 
    equity. All such rights and remedies shall be cumulative and may be 
    enforced concurrently or individually from time to time.  Except as set 
    forth expressly in this Section and to the extent permitted by 
    applicable law, Lessee waives any rights now or hereafter conferred by 
    statute or otherwise which may require Lessor to sell, lease or use the 
    Software and Equipment in mitigation of Lessor's damages or which may 
    otherwise limit or modify any of Lessor's rights or remedies and Lessee 
    waives any rights conferred upon Lessee by UCC Sections 2A-508 through 
    2A-522. 

23. BANKRUPTCY OF SOFTWARE LICENSORS 
    --------------------------------

    The bankruptcy of the Software Licensor or Equipment manufacturer 
    or vendor shall not be a valid cause for Lessee to terminate Lease 
    Payments to Lessor. Lessee shall take all action necessary to protect 
    Lessee's rights to use the Software under Section 365 of the Bankruptcy 
    Code.  Lessee shall elect to retain its rights under the Bankruptcy 
    Code to use the Software, and to the extent the Software License grants 
    customer access to the source code, Lessee shall make written request 
    under the Bankruptcy Code of the Bankruptcy Trustee to obtain the 
    source code.  Lessee shall take other reasonable action to protect its 
    rights to use the Software.  In the event Lessee fails to take the 
    action specified above, Lessee appoints Lessor its Attorney-in-fact, to 
    secure, at Lessor's sole discretion and at Lessee's cost, the right to 
    use the Software for Lessee. 

24. MISCELLANEOUS 

    (a) NOTICES.  Service of all notices under the Lease shall be 
    sufficient if delivered personally or mailed to Lessee at the address 
    above set forth, or to such other address as each party may substitute 
    by notice to the other.  Notice by mail shall be effective when 
    deposited in the United States mail, duly addressed and with postage 
    prepaid. 
    
    (b) ENTIRE AGREEMENT.  The Lease is the complete and exclusive 
    statement of the 

                                                                        Page 6

    agreement between the parties, superseding all proposals or prior 
    agreements, oral or written, and all other communications between the 
    parties relating to the subject matter. 

    (c) GOVERNING LAW.  This Lease shall be governed by and construed 
    in accordance with the laws of the Commonwealth of Pennsylvania. 

    (d) SEVERABILITY.  If any provision shall be held to be invalid or 
    unenforceable, the validity and enforceability of the remaining 
    provisions shall not in any way be affected or impaired. 

    (e) QUIET ENJOYMENT.  So long as Lessee shall not be in default, 
    Lessor shall not interfere with Lessee's right of quiet enjoyment and 
    use of the Software and Equipment. 

    (f) FURTHER DOCUMENTS.  Lessee shall provide Lessor with such 
    documents as Lessor may reasonably request, including documents 
    relating to preserving the security of Lessor, or financing statements 
    under the Uniform Commercial Code.  Lessor may execute Uniform 
    Commercial Code financing statements for and on behalf of Lessee for 
    the purpose of indicating Lessor's interest in the Collateral. 

    (g) TIME.  Time is of the essence with respect to this Lease.

    (h) COUNTERPARTS.  This Lease may be executed in any number of 
    counterparts, each of which shall be deemed an original, but all such 
    counterparts together shall constitute but one instrument.  No security 
    interest in this Lease or the Collateral or any sums payable hereunder 
    may be created through the transfer or possession of any counterpart 
    other than Counterpart No. 1. 

    (i) SURVIVAL OF OBLIGATION. All agreements, representations, 
    indemnities and warranties contained in this Agreement or any related 
    document shall survive the expiration or other termination of this 
    Agreement. 

    (j) SUCCESSORS.  This Lease shall be binding upon and inure to the 
    benefit of Lessor and Lessee and their respective successors and 
    assigns, unless otherwise expressly provided herein. 

    (k) DISPUTES.  THE PARTIES CONSENT TO THE NON-EXCLUSIVE 
    JURISDICTION OF THE STATE AND FEDERAL COURTS IN PENNSYLVANIA AND 
    VIRGINIA IN CONNECTION WITH ANY DISPUTE UNDER THIS LEASE, AND LESSEE 
    WAIVES ITS RIGHT TO TRIAL BY JURY.

                         NETWORK SERVICES AGREEMENT

                                            
         THIS AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT AND NETWORK 
SERVICES AGREEMENT (the "Amendment") is entered into as of June 28, 1996 by 
and between PSINET INC. ("Seller") and MINDSPRING ENTERPRISES, INC. ("Buyer").

         WHEREAS, Seller and Buyer are parties to that certain Asset Purchase 
Agreement of even date herewith (the "Purchase Agreement") and that certain 
Network Services Agreement of even date herewith (the "Network Services 
Agreement"); and

         WHEREAS, capitalized terms that are used but not otherwise defined 
herein shall have the meanings ascribed to them in the Purchase Agreement; 
and 

         WHEREAS, Seller and Buyer desire to amend the Purchase Agreement and 
the Network Services Agreement, and provide for the replacement of the First 
Note (as defined in the Purchase Agreement), all in accordance with and 
subject to the terms and conditions hereinafter set forth;

         NOW THEREFORE, in consideration of the foregoing and of the mutual 
covenants and agreements hereinafter set forth, the parties hereto hereby 
amend the Purchase Agreement, the Network Services Agreement and the First 
Note, as follows:

         1.  The following shall be inserted at the end of the section 
entitled "Conversion" in the First Note, as replaced in accordance with 
Paragraph 2 hereof, and in the corresponding section of each of the forms of 
the First Note, the Second Note, the Third Note and the Fourth Note, attached 
as Exhibits 2.3 (a), (b), (c), and (d), respectively, to the Purchase 
Agreement:

             Notwithstanding the foregoing, in no event shall this Note 
      be convertible into Common Stock if, as a result of such conversion, 
      the aggregate amount of Common Stock that would be issued pursuant to 
      the Notes (as such term is defined in the Purchase Agreement, as 
      defined herein) exceeds 19.9% of the issued and outstanding Common 
      Stock as of June 28, 1996, unless approval by the Company's 
      stockholders has been obtained.  In addition, if the approval of the 
      Company's stockholders referred to in the immediately preceding 
      sentence has not been obtained by the time this Note would otherwise be 
      convertible as provided above, the registered owner of this Note may 
      convert this Note in part on the terms and conditions set forth in this 
      section entitled "Conversion" (with the written notice of conversion to 
      specify the amount to be converted); PROVIDED, 



<PAGE>

      HOWEVER, that if the registered holder of this Note converts this Note 
      in part pursuant to this sentence, the registered holder shall present 
      to Buyer for conversion the Note representing the unconverted 
      balance of this Note within ten (10) days following receipt of written 
      notice from Buyer that the stockholders consent referred to in the 
      immediately preceding sentence has been obtained.


         2.  The defined term "Purchase Agreement" in the forms of the First 
Note, the Second Note, the Third Note and the Fourth Note is hereby amended 
to include the following: 

              which term shall include all amendments thereto.

         3.  Upon execution of this Amendment, Buyer shall re-execute the 
First Note in the form attached hereto as Exhibit A and deliver the same to 
Buyer, and, promptly thereafter, Seller shall return to Buyer the original 
First Note, which shall be deemed replaced by such re-executed First Note.

         4.  If, as of the date that notice of the next annual meeting of 
stockholders of Buyer is required to be mailed, any of the Notes remain 
outstanding such that upon conversion, the aggregate amount of Common Stock 
that would be issued pursuant to all of the Notes would exceed 19.9% of the 
issued and outstanding Common Stock as of June 28, 1996, then Buyer shall 
request from its stockholders at such annual meeting the approval referred to 
in Paragraph 1 above.

         5.   By their signatures hereto, ITC Holding Company, Inc. and 
Charles M. Brewer agree to vote all shares of Common Stock, and other capital 
stock of Buyer, held by them in favor of the approval referred to in 
paragraph 1 above, whenever such approval is requested by Buyer of its 
stockholders.

         6.   Section 2.3(c) of the Purchase Agreement is hereby amended by 
inserting the following at the end thereof:

              or, in the event that funds were raised through a stock 
      offering or other financing which Buyer would have been required to use 
      to pay down the principal and accrued but unpaid interest under the 
      Third Note pursuant to Section 3.4 after the principal and accrued but 
      unpaid interest under the First Note and the Second Note were paid in 
      full, Buyer shall pay to Seller such funds, not to exceed what would 
      otherwise be the initial principal amount of the Third Note, and the 
      initial principal amount of the Third Note so issued shall be reduced 
      accordingly.
      
         7.   Section 2.3(d) of the Purchase Agreement is hereby amended 
by inserting the following at the end thereof:      

                                       2

<PAGE>

              , or, in the event that funds were raised through a stock 
      offering or other financing which Buyer would have been required to use 
      to pay down the principal and accrued but unpaid interest under the 
      Fourth Note pursuant to Section 3.4 after the principal and accrued but 
      unpaid interest under the First Note, the Second Note and the Third Note 
      were paid in full, Buyer shall pay to Seller such funds, not to exceed 
      what would otherwise be the initial principal amount of the Fourth Note, 
      and the initial principal amount of the Fourth Note so issued shall be 
      reduced accordingly.

         8.  The period at the end of Section 2.3(d) of the Purchase 
Agreement is hereby replaced with a semicolon and the following is hereby 
added to the Purchase Agreement as new Section 2.3(e):

         (e)    Buyer shall deliver to Seller within ten (10) days after the 
Third Measurement Date a fully executed copy of the Fifth Note, or, in the 
event that funds were raised through a stock offering or other financing 
which Buyer would have been required to use to pay down the principal and 
accrued but unpaid interest under the Fifth Note pursuant to Section 3.4 
after the principal and accrued but unpaid interest under the First Note, the 
Second Note, the Third Note and the Fourth Note were paid in full, Buyer 
shall pay to Seller such funds, not to exceed what would otherwise be the 
initial principal amount of the Fifth Note, and the initial principal amount 
of the Fifth Note so issued shall be reduced accordingly.

         9.  The phrase "First Measurement Date" in Section 3.3(a) of the 
Purchase Agreement is hereby replaced with "November 30, 1996."  The 
following is hereby inserted after the last sentence of Section 3.3(a) of the

         (b)  (i)  After the First Closing Date, Buyer shall use reasonable 
efforts to seek confirmation from the Subscribers to Seller's Pipeline 
service (A) that such Subscribers desire to be switched to Buyer's network 
and (B) of the Subscribers' relevant subscription information.  After the 
Second Closing, Buyer shall produce and ship software and other necessary 
materials (collectively, "Kits") to allow Subscribers, who have confirmed 
that they desire to switch to Buyer's network to make such switch, promptly 
following receipt of such confirmation.  Buyer shall pay the costs of such 
production and shipment initially, but on the Second Measurement Date and 
upon presentation of reasonably 

                                       3

<PAGE>

satisfactory documentation of such costs Seller shall pay to Buyer fifty 
percent (50%) of Buyer's costs actually incurred in connection with such 
production and shipment and Buyer shall offset the amount due from Seller 
against the payments otherwise due Seller under the Notes.

              (ii)  After the First Closing Date, Buyer shall use reasonable 
efforts to seek confirmation from the Subscribers to Seller's Interramp 
service (A) that such Subscribers desire to be switched to Buyer's network 
and (B) of the Subscribers' relevant subscription information.  After the 
Second Closing, Buyer shall assist Subscribers to Seller's Interramp service, 
who have confirmed that they desire to switch to Buyer's network, to 
configure their current software to work on Buyer's network.  After the 
Second Closing, Buyer shall also produce and ship Kits upon request to 
Subscribers to Seller's Interramp service who have requested such Kits and 
have confirmed their desire to switch to Buyer's network.  Buyer shall pay 
the costs of such production and shipment initially, but on the Second 
Measurement Date and upon presentation of reasonably satisfactory 
documentation of such costs Seller shall pay to Buyer fifty percent (50%) of 
Buyer's costs actually incurred in connection with such production and 
shipment and Buyer shall offset the amount due from Seller against the 
payments otherwise due Seller under the Notes.

              (iii)  Notwithstanding, the foregoing provisions of this 
Section 3.3(b), Subscribers who do not transition to Buyer's network shall be 
considered Continuing Subscribers if they otherwise satisfy the definition of 
"Continuing Subscribers" set forth in Annex 1 to this Agreement.  In no event 
shall the aggregate payments made by Seller to Buyer under (i) and (ii) above 
exceed $400,000.

         11.  Seller's total obligations under Sections 3.3(d) and (e) of the 
Purchase Agreement shall be satisfied by paying Buyer Three Thousand Dollars 
($3,000) at the Second Closing.

         12.  The phrase "First Measurement Date" in Section 3.3(f) of the 
Purchase Agreement is hereby replaced with "date specified by Buyer in a 
written notice to Seller but in no event later than December 31, 1996."

restated as follows:

proceeds of such an offering to pay down the Notes according to the following 
formula:

                                       4

<PAGE>

         (a)  if the net proceeds (which term shall mean gross proceeds less 
normal offering expenses) of any offering or other financing exceed thirty 
million dollars ($30,000,000.00), Buyer shall use all of such net proceeds, 
up to the amount of principal and accrued but unpaid interest outstanding 
under the Notes, to pay down the Notes promptly following the closing of such 
offering or other financing;

         (b)  if the net proceeds of any offering or other financing are 
between twenty and thirty million dollars ($20,000,000.00-30,000,000.00), 
Buyer shall use seventy-five percent (75%) of such net proceeds, up to the 
amount of principal and accrued but unpaid interest outstanding under the 
Notes, to pay down the Notes promptly following the closing of such offering 
or other financing;

         (c)  if the net proceeds of any offering or other financing are 
between ten and twenty million dollars ($10,000,000.00-20,000,000.00), Buyer 
shall use fifty percent (50%) of such net proceeds, up to the amount of 
principal and accrued but unpaid interest outstanding under the Notes, to pay 
down the Notes promptly following the closing of such offering or other 
financing; and

         (d)  if the net proceeds of any offering or other financing are 
between one and ten million dollars ($1,000,000.00 - $10,000,000.00), Buyer 
shall use thirty-three percent (33%) of such net proceeds, up to the amount

    FOR VALUE RECEIVED, the undersigned, MINDSPRING ENTERPRISES, INC., a 
Delaware corporation (herein called the "Company"), hereby promises to pay to 
PSINET, INC., a New York corporation, or registered assigns (hereinafter 
called the "Payee"), the principal sum of Two Million Dollars ($2,000,000.00) 
(the "Principal", which shall be subject to increase or decrease as set forth 
below), together with interest on the unpaid principal amount hereof from the 
date hereof, until paid in full, said interest to be due and payable on the 
first anniversary of the date of this Note, when the entire balance of this 
Note shall be due and payable in full, equal to the interest rate published 
as the "prime rate" in the "Money Rates" section of THE WALL STREET JOURNAL 
(the "PRIME RATE") plus three percent (3%).  In no event, however, shall this 
Note bear interest in excess of the maximum rate of interest permitted by 
applicable law.  All payments hereunder shall be made in lawful money of the 
United States of America, and shall be subject to the offset and deduction 
provisions described herein.

    In the event of a change in the Prime Rate, interest on the outstanding
principal balance hereof will be adjusted accordingly, it being the intent
hereof that the rate of said interest shall increase or decrease simultaneously
with and to the same extent as an increase or decrease in the Prime Rate. 
Should THE WALL STREET JOURNAL during the term hereof abolish or abandon the
practice of publishing the Prime Rate, then the Prime Rate used during the
remainder of said term shall be the rate from time to time announced by
Citibank, N.A. as its "prime rate".



                                       1

    In the event that this Note is not redeemed in full within ninety (90) days
after the date of this Note, the Principal shall increase by five percent (5%)
of the Principal then outstanding.  The Principal shall increase in a like
manner each ninety (90) days thereafter that this Note is not redeemed in full.

LATE CHARGES

    If the entire amount of any principal payment and/or interest is not paid
in full within five (5) days after the date when due, the Company shall pay to
the Payee a late fee equal to two percent (2%) of the amount not paid.

SALE OF NOTE; TRANSFER OF SECURITIES

    Neither this Note nor the shares of Common Stock issuable upon exercise of
the conversion rights herein have been registered under the Securities Act of
1933, as amended (the "1933 Act") or under the securities laws of any state. 
Neither this Note nor any such shares, when issued, may be sold, transferred,
pledged or hypothecated in the absence of (1) an effective registration
statement for this Note, or the shares, as the case may be, under the 1933 Act,
and such registration or qualification as may be necessary under the securities
laws of any state, or (2) an opinion of counsel in form and substance reasonably
satisfactory to the Company that such registration or qualification is not
required.  The Company may cause the certificate or certificates evidencing all
or any of the shares issued upon exercise of the conversion rights contained in
this Note before such registration and qualification of such shares to bear the
following legend:

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

    This Note shall be registered on books of the Company that shall be kept at
its principal office for that purpose, and shall be transferable only on such
books by the registered owner hereof in person or by duly authorized attorney
upon surrender of this Note properly endorsed, and only in compliance with the
next preceding paragraph hereof.

REDEMPTION

    The Company may redeem this Note, by payment, in the case of full
redemption, in full of the entire principal amount thereof then outstanding,
together with all interest accrued thereon until the date of redemption.  In the
case of any partial redemption hereof, payments shall be applied first to
payment of any accrued interest owing hereunder, and then against principal
owing hereunder.

CONVERSION

    In the event that this Note is not redeemed in full by the first
anniversary of the date of this Note, the registered owner of this Note is
hereby given the right to convert all, but not less than all, of the total
amount due under this Note into fully paid and nonassessable shares of the
common stock, $0.01 par value per share, of the Company (the "Common Stock") as
follows:

         (1)  CONVERSION PRICE.  The registered owner of this Note shall
receive one share of Common Stock for a price equal to the closing price of the
common stock of the Company traded on the Nasdaq Stock Market as of the end of
the trading day on the Second Closing Date, PROVIDED, HOWEVER, that if the
Second Closing Date has not occurred, then as of the end of the trading day on
the First Closing Date (as defined in the Purchase Agreement).

         (2)  PROCEDURE FOR CONVERSION.  In order to exercise the conversion
privilege, the registered owner shall surrender this Note to the Company at its
main office, accompanied by written notice to the Company that such owner elects
to convert the total amount due under this Note and an opinion of counsel in
form and substance satisfactory to the Company that the issuance of shares of
Common Stock upon such conversion has been registered under the 1933 Act and
registered or qualified as necessary under applicable state securities laws, or
that such registration and qualification are not required.  As promptly as
practicable after the receipt of such notice and opinion and surrender of this
Note as aforesaid, the Company shall issue and deliver to the registered owner a
certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of this Note (or specified portion hereof).  Such
conversion shall be deemed to have been effected at the close of business on the
date on which such notice shall have been received by the Company and this Note
shall have been surrendered as aforesaid.  If this Note is converted in part
only, upon such conversion the Company shall execute and deliver to the Payee,
at the expense of the Company, a new Note in principal amount equal to the
unconverted portion of this Note.  No fractional shares shall be issued upon
conversion of this Note and any portion of the principal  or interest hereof
that would otherwise be convertible into a fractional share shall be paid in
cash.

                                       3

<PAGE>

    The Company shall at all times reserve and keep available a number of its
authorized but unissued shares of Common Stock sufficient to permit the exercise
in full by the registered owner of this Note of its conversion rights hereunder.

    Notwithstanding the foregoing, in no event shall this Note be convertible
into Common Stock if, as a result of such conversion, the aggregate amount of
Common Stock that would be issued pursuant to the Notes (as such term is defined
in the Purchase Agreement, as defined herein) exceeds 19.9% of the issued and
outstanding Common Stock as of June 28, 1996, unless approval by the Company's
stockholders has been obtained.  In addition, if the approval of the Company's
stockholders referred to in the immediately preceding sentence has not been
obtained by the time this Note would otherwise be convertible as provided above,
the registered owner of this Note may convert this Note in part on the terms and
conditions set forth in this section entitled "Conversion" (with the written
notice of conversion to specify the amount to be converted); PROVIDED, HOWEVER,
that if the registered holder of this Note converts this Note in part pursuant
to this sentence, the registered holder shall present to Buyer for conversion
the Note representing the unconverted balance of this Note within ten (10) days
following receipt of written notice from Buyer that the stockholders consent
referred to in the immediately preceding sentence has been obtained.

DEFAULT

    In case of the failure to pay, when due, the principal, any interest, or
any other sum payable hereunder, and continuance of such failure for five (5)
business days after the date on which such principal, interest or other sum is
due (whether upon maturity hereof, upon any installment payment date, upon any
prepayment date, upon acceleration, or otherwise), the Payee may declare this
Note to be due and payable in full.

MISCELLANEOUS

    Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Note, and (in case of loss, theft or
destruction) of indemnity reasonably satisfactory to it, and upon reimbursement
to the Company of all reasonable expenses incidental thereto, and upon surrender
and cancellation of this Note, if mutilated, the Company will make and deliver a
new Note of like tenor in the principal amount of this Note then outstanding in
lieu of such Note.  Any Note so made and delivered shall be dated as of the date
to which interest has been paid on the Note lost, stolen, destroyed or
mutilated.

    The Company shall have the right to offset and/or deduct, from time to time
and at any time, any amounts of principal or interest payable under this Note
against Losses (as defined in the Asset Purchase Agreement by and between the
Company and Payee, dated as of June 28, 1996 ("Purchase Agreement", which term


                                       4

shall include all amendments thereto)) asserted against, resulting to, imposed
upon or incurred by the Company for which the Company has a right or claim for
indemnification pursuant to ARTICLE 10 of the Purchase Agreement 

    The Company hereby waives presentment, demand, notice, protest and other
demands and notices in connection with the delivery, acceptance or enforcement
of this Note.

    No delay or omission on the part of the Payee in exercising any right
hereunder shall operate as a waiver of such right or of any other right under
this Note, and a waiver, delay or omission on any one occasion shall not be
construed as a bar to or waiver of any such right on any future occasion.

    The Company hereby agrees to pay on demand all costs and expenses,
including, without limitation, reasonable attorneys' fees and legal expenses,
incurred or paid by Payee in enforcing this Note.

    The terms of this Note shall be governed by and construed in accordance
with the laws of the State of New York (but not including the choice of law
rules thereof).

    This Note shall not be valid or obligatory for any purpose until
authenticated by the execution hereof by the Chairman, President or a Vice
President of the Company and registered upon the books of the Company as
hereinabove provided.

                                                                 Exhibit 99.1

RISK FACTORS  

   FROM TIME TO TIME, IN BOTH WRITTEN REPORTS AND IN ORAL STATEMENTS BY 
PSINET SENIOR MANAGEMENT, EXPECTATIONS AND OTHER STATEMENTS ARE EXPRESSED 
REGARDING FUTURE PERFORMANCE OF THE COMPANY.  THESE FORWARD-LOOKING 
STATEMENTS ARE INHERENTLY UNCERTAIN AND INVESTORS MUST RECOGNIZE THAT EVENTS 
COULD TURN OUT TO BE DIFFERENT THAN SUCH EXPECTATIONS AND STATEMENTS. KEY 
FACTORS IMPACTING CURRENT AND FUTURE PERFORMANCE ARE DISCUSSED IN THE 
COMPANY'S ANNUAL REPORT ON FORM 10-K AND OTHER FILINGS WITH THE SECURITIES 
AND EXCHANGE COMMISSION. IN ADDITION, THE FOLLOWING RISK FACTORS AS WELL AS 
THE OTHER INFORMATION IN THIS QUARTERLY REPORT SHOULD BE CONSIDERED IN 
EVALUATING THE COMPANY AND ITS BUSINESS. 

LIMITED HISTORY OF OPERATIONS; OPERATING DEFICIT; CONTINUING LOSSES; 
POTENTIAL FLUCTUATIONS IN OPERATING RESULTS

   The Company began offering its services in 1990. Although the Company has 
experienced revenue growth on an annual basis, it has incurred losses and 
experienced negative cash flow from operations during each of its last three 
fiscal years including a loss of $53.2 million and negative cash flow from 
operations of $30.1 million for 1995 and a loss of $38.3 million and negative 
cash flow from operations of $28.4 million for the nine months ended 
September 30, 1996.  At September 30, 1996, the Company had a retained 
deficit of $99.8 million. There can be no assurance that revenue growth will 
continue or that the Company will achieve profitability or positive cash flow 
from operations in the future.  The Company expects to focus in the near term 
on continuing to increase its corporate subscriber base and expanding its 
consumer wholesaling strategy which will require it to continue to incur 
expenses for marketing, network infrastructure, personnel and the development 
of new services and software, and thereby may adversely impact cash flow and 
operating performance. The Company also plans to continue to enhance the 
PSINet network and the administrative and operational infrastructure 
necessary to support its Internet access service domestically and 
internationally. As a result, the Company believes that it will continue to 
incur losses throughout 1996, and there can be no assurance that the Company 
will achieve profitability in the future.  

   The Company's operating results have fluctuated in the past and may 
fluctuate significantly in the future as a result of a variety of factors, 
some of which are outside of the Company's control, including general 
economic conditions, specific economic conditions in the Internet access 
industry, user demand for the Internet, capital expenditures and other costs 
relating to the expansion of operations, the timing of customer 
subscriptions, the introduction of new services by the Company or its 
competitors, the mix of services sold and the mix of channels through which 
those services are sold, pricing changes and new product introductions by the 
Company and its competitors and delays in obtaining sole or limited source 
equipment. As a strategic response to a changing competitive environment, the 
Company may elect from time to time to make certain pricing, service or 
marketing decisions or acquisitions that could have a material adverse effect 
on the Company's business, results of operations and cash flow. In addition, 
due to changing market conditions, substantial amortization expenses may be 
accelerated in accordance with generally accepted accounting principles to 
recognize changes in the expected life of acquisitions and related long-lived 
assets. 

COMPETITION

   The market for data communications services, including Internet access 
services, is highly competitive. The industry has relatively insignificant 
barriers to entry and numerous entities competing for the same customers. 
PSINet expects that competition will continue to intensify. The Company 
believes that the primary competitive factors for the provision of Internet 
services are price, quality of service, reliability, technical expertise, 
ease of use, variety of value-added services, quality and availability of 
customer support, experience of the supplier, geographic coverage and name 
recognition. PSINet's success in this market will depend heavily upon its 
ability to provide high quality Internet connectivity and value-added 
Internet services at competitive prices. 




                                      21


<PAGE>


   The Company's current and prospective competitors generally may be divided 
into the following three groups: (1) other Internet access providers, such as 
Bolt, Beranek & Newman Inc., and other national and regional providers; (2) 
telecommunications companies, such as AT&T Corp. ("AT&T"), MCI Communications 
Corporation ("MCI"), MFS Communications Co., Inc. ("MFS"), Sprint, Inc., 
regional Bell operating companies ("RBOCs") and various cable television 
companies; and (3) on-line services providers, such as America Online, Inc. 
("America Online"), CompuServe Incorporated ("CompuServe"), Delphi Internet 
Services (a division of News Corp.), the Microsoft Network ("MSN"), a service 
of Microsoft Corp. ("Microsoft"), NETCOM On-Line Communications Services, 
Inc. ("NETCOM"), and Prodigy. Many of these competitors have greater market 
presence, engineering and marketing capabilities, and financial, 
technological and personnel resources than those available to PSINet. As a 
result, they may be able to develop and expand their communications and 
network infrastructures more quickly, adapt more swiftly to new or emerging 
technologies and changes in customer requirements, take advantage of 
acquisition and other opportunities more readily, and devote greater 
resources to the marketing and sale of their products than can PSINet. In 
addition, the ability of some of the Company's competitors to bundle other 
services and products with Internet access services could place PSINet at a 
competitive disadvantage. 

   PSINet believes that competition will intensify as new competitors, 
including large computer hardware, software, media and other technology and 
telecommunications companies, enter the Internet services market and as 
existing competitors form alliances with or acquire other companies. The 
recent merger of UUNET Technologies, Inc. ("UUNET") with MFS and the pending 
merger of MFS and WorldCom, Inc., for example, may create the potential for 
network expense reductions which could result in a competitive advantage for 
the combined entity.  Such acquisitions, alliances and expanded service 
offerings may permit the Company's competitors to devote greater resources to 
the development and marketing of new competitive products and services and 
the marketing of existing competitive products and services. 

   As PSINet expands its operations outside the United States, it will 
encounter new competitors and competitive environments.  In some cases, the 
Company will be forced to compete with and buy services from government owned 
or subsidized telecommunications providers, some of which may enjoy a 
monopoly on telecommunications services essential to the Company's business. 
There can be no assurance that the Company will be able to purchase such 
services at a reasonable price or at all. In addition to the risks associated 
with the Company's previously described competitors, foreign competitors may 
possess a better understanding of their local markets and better working 
relationships with local infrastructure providers. There can be no assurance 
that the Company can obtain similar levels of local knowledge, and failure to 
obtain that knowledge could place the Company at a significant competitive 
disadvantage. 

   As a result of industry competition, the Company expects to encounter 
pricing pressure, which in turn could result in reductions in the average 
selling price of the Company's services. For example, certain of the 
Company's competitors which are telecommunications companies, including AT&T 
and MCI, may be able to provide customers with reduced or free communications 
costs in connection with their Internet access services or offer Internet 
access as a standard component of their overall service package, thereby 
increasing price pressure on PSINet. The Company has in the past reduced 
prices on certain of its Internet access options and may continue to do so in 
the future. There can be no assurance that the Company will be able to offset 
the effects of any such price reductions with an increase in the number of 
its customers, higher revenue from enhanced services, cost reductions or 
otherwise.  PSINet is not able presently to predict the impact which future 
growth in the Internet access and on-line services businesses will have upon 
competition in the industry.  Increased price or other competition could 
result in erosion of the Company's market share and could have a material 
adverse effect on the Company's business, financial condition and results of 
operations. There can be no assurance that the Company will have the 
financial resources, technical expertise or marketing and support 
capabilities to continue to compete successfully.  





                                      22


<PAGE>

RECENT ENTRY INTO CONSUMER WHOLESALING BUSINESS

   In response to competitive considerations in the market for individual 
customers, the Company has determined to focus its efforts in this market on 
the high-end business user and has altered its strategy to include the 
provision of wholesale services to consumer-oriented Internet service 
providers in the United States, rather than providing the consumer services 
directly.  There can be no assurance that the Company will be successful in 
implementing this strategy change or marketing to high-end business users or 
other Internet service providers or that the Company will be able to offset 
the effects of any revenue reductions with respect to its new consumer 
Internet service focus with an increase in the number of its customers, 
higher revenue from enhanced services, cost reductions or otherwise.

RISKS OF GROWTH AND EXPANSION

   The Company had expanded its network to approximately 345 POPs as of 
September 30, 1996 and plans to continue to add additional POPs and expand  
the capacity of existing POPs as needed during the remainder of 1996 and 
1997.  The Company's rapid growth has placed, and in the future may continue 
to place, a significant strain on the Company's administrative, operational 
and financial resources and increased demands on its systems and controls.  
The Company anticipates that its consumer wholesale focus, as well as other 
business growth, may require continued enhancements to and expansion of its 
network.  Competition for qualified personnel in the internetworking industry 
is intense and there are a limited number of persons with knowledge of and 
experience in the Internet service industry. The process of locating, 
training and successfully integrating qualified personnel into the Company's 
operations is often lengthy and expensive. There can be no assurance that the 
Company will be successful in attracting, integrating and retaining such 
personnel. In addition, there can be no assurance that the Company's 
operating and financial control systems and infrastructure will be adequate 
to maintain and effectively monitor future growth. The inability to continue 
to upgrade the networking systems or the operating and financial control 
systems, the inability to recruit and hire necessary personnel, the inability 
to successfully integrate new personnel into the Company's operations, the 
inability to manage its growth effectively or the emergence of unexpected 
expansion difficulties could adversely affect the Company's business, results 
of operations and financial condition. 

NEED FOR ADDITIONAL CAPITAL TO FINANCE GROWTH AND CAPITAL REQUIREMENTS

   The Company expects to continue to enhance its network in order to 
maintain its competitive position and continue to meet the increasing demands 
for service quality, availability and competitive pricing.  As of September 
30, 1996, the Company's network was comprised of more than 345_POPs.  Based 
upon its present business plan, the Company believes that working capital, 
funds from operations, existing credit facilities and additional borrowings 
which the Company expects to be able to obtain when needed, will be 
sufficient to meet the presently anticipated working capital and capital 
expenditure requirements of its existing operations.  The Company may seek to 
raise additional funds in order to take advantage of unanticipated 
opportunities, including more rapid international expansion or acquisitions 
of complementary businesses or technologies, or to develop new products or 
otherwise respond to unanticipated competitive pressures.  There can be no 
assurance that the Company will be able to raise such funds on favorable 
terms or at all.  In the event that the Company is unable to obtain such 
additional funds or is unable to obtain such additional funds on acceptable 
terms, the Company may determine not to enter into various expansion 
opportunities.

RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION

   A component of the Company's strategy is its planned expansion into 
international markets. To date, the Company has only limited experience in 
providing international Internet service. There can be no assurance as to the 
ability of the Company to obtain the capital it requires to finance its 
expansion into these markets. In addition, there can be no assurance that the 
Company will be able to obtain the permits and operating licenses required 
for it to operate, to hire and train employees or to market, sell and deliver 
high quality services in these markets. In addition to the uncertainty as to 
the Company's ability to expand its international presence, there are certain 
risks inherent to doing business on an international level, such as 
unexpected changes in regulatory requirements, tariffs, 



                                      23
<PAGE>

customs, duties and other trade barriers, difficulties in staffing and 
managing foreign operations, longer payment cycles, problems in collecting 
accounts receivable, political instability, expropriation, nationalization, 
war, insurrection and other political risks, fluctuations in currency 
exchange rates, foreign exchange controls which restrict or prohibit 
repatriation of funds, technology export and import restrictions or 
prohibitions, delays from customs brokers or government agencies, seasonal 
reductions in business activity during the summer months in Europe and 
certain other parts of the world and potentially adverse tax consequences, 
which could adversely impact the success of the Company's international 
operations. The Company may need to enter into additional joint ventures or 
other strategic relationships with one or more third parties in order to 
successfully conduct its foreign operations. There can be no assurance that 
such factors will not have an adverse effect on the Company's future 
international operations and, consequently, on the Company's business, 
financial condition and results of operations. In addition, there can be no 
assurance that laws or administrative practice relating to taxation, foreign 
exchange or other matters of countries within which the Company operates will 
not change. Any such change could have a material adverse effect on the 
Company's business, financial condition and results of operations. 

RISKS ASSOCIATED WITH ACQUISITIONS AND STRATEGIC ALLIANCES

   As part of its business strategy, the Company expects to seek to develop 
strategic alliances both domestically and internationally and/or to acquire 
assets and businesses principally relating to or complementary to its current 
operations. The Company has no present commitments or agreements with respect 
to any material strategic alliance or acquisition except as otherwise 
disclosed in this Form 10-Q and the Company's other periodic reports filed 
with the Securities and Exchange Commission. Any such future strategic 
alliances or acquisitions would be accompanied by the risks commonly 
encountered in strategic alliances with or acquisitions of companies. Such 
risks include, among other things, the difficulty of assimilating the 
operations and personnel of the companies, the potential disruption of the 
Company's ongoing business, the inability of management to maximize the 
financial and strategic position of the Company by the successful 
incorporation of licensed or acquired technology and rights into the 
Company's service offerings, the maintenance of uniform standards, controls, 
procedures and policies and the impairment of relationships with employees 
and customers as a result of changes in management. There can be no assurance 
that the Company would be successful in overcoming these risks or any other 
problems encountered in connection with such strategic alliances or 
acquisitions. 

   PSINet has entered into strategic alliances in Korea and The Netherlands 
and, most recently, has entered into an arrangement to form a joint venture 
for the purpose of building a network and providing Internet services 
throughout Europe. The Company has no prior experience working with these 
companies. This lack of experience as well as the international nature of 
these ventures could increase the likelihood of failure and materially 
adversely affect the Company's results of operations.  Additionally, the 
Company may be required to issue Company stock in connection with its 
obligation to purchase an additional 10% interest in World Online B.V. and 
has entered into option arrangements in connection with the Company's 
European joint venture which could result in the issuance of Company stock to 
the Company's joint venture partner.  

   In addition, if the Company were to proceed with one or more significant 
acquisitions in which the consideration consists of cash, a substantial 
portion of the Company's available cash could be used to consummate the 
acquisitions. If the Company were to consummate one or more significant 
acquisitions or strategic alliances in which the consideration consists of 
stock, shareholders of the Company could suffer a significant dilution of 
their interests in the Company. Many of the businesses that might become 
attractive acquisition candidates for the Company may have significant 
goodwill and intangible assets, and acquisition of these businesses, if 
accounted for as a purchase, would typically result in substantial 
amortization charges to the Company.  In the event the Company consummates 
additional acquisitions in the future that must be accounted for as 
purchases, such acquisitions would likely further increase the Company's 
amortization expenses and the length of time over which they are reported. In 
connection with acquisitions, the Company could incur substantial expenses, 
including the fees of financial advisors, attorneys and accountants, the 
expenses of integrating the business of the acquired company or the strategic 
alliance with the Company's business and any expenses associated with 
registering shares of the Company's capital stock, if such 

                                      24
<PAGE>

shares are issued. Such expenses, in addition to the financial impact of such 
acquisitions, could have a material adverse effect on the Company's business, 
financial condition and results of operations and could cause substantial 
fluctuations in the Company's quarterly and yearly operating results. 

DEPENDENCE ON KEY PERSONNEL

   The Company's success depends to a significant degree upon the continued 
contributions of its senior management team and technical, marketing and 
sales personnel. The Company's employees may voluntarily terminate their 
employment with the Company at any time.  Competition for qualified employees 
and personnel in the internetworking industry is intense and there are a 
limited number of persons with knowledge of and experience in the Internet 
service industry. The Company's success also will depend on its ability to 
attract and retain qualified management, marketing, technical and sales 
executives and personnel. The process of locating such personnel with the 
combination of skills and attributes required to carry out the Company's 
strategies is often lengthy. The loss of the services of key personnel, or 
the inability to attract additional qualified personnel, could have a 
material adverse effect on the Company's results of operations, product 
development efforts and ability to expand its network infrastructure. There 
can be no assurance that the Company will be successful in attracting and 
retaining such executives and personnel. If the Company is unable to hire 
additional sales and marketing personnel, the marketing and sale of existing 
and new products will likely be adversely impacted. Any such event could have 
a material adverse effect on the Company's business, financial condition and 
results of operations. 

POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED THROUGH NETWORK; PENDING AND 
THREATENED LITIGATION

   The law relating to the liability of on-line services companies and 
Internet access providers for information carried on or disseminated through 
their systems is currently unsettled in the United States. Several private 
lawsuits seeking to impose such liability upon on-line services companies and 
Internet access providers are currently pending. In addition, recently 
enacted federal legislation prohibits and imposed liability for the 
transmission on the Internet of certain types of information and content. In 
one case brought against an Internet access provider, RELIGIOUS TECHNOLOGY 
CENTER V. NETCOM ON-LINE COMMUNICATIONS SERVICES, INC., a Federal district 
court ruled that under certain circumstances Internet access providers could 
be held liable for copyright infringement.  The imposition upon the Company 
and other Internet access providers or Web hosting sites of potential 
liability for information carried on or disseminated through their systems 
could require the Company to implement measures to reduce its exposure to 
such liability, which may require the expenditure of substantial capital and 
other resources, or to discontinue certain product or service offerings. The 
increased attention focused upon liability issues as a result of these 
lawsuits and legislative proposals could impact the growth of the Internet. 

   The Company carries errors and omissions insurance with a basic policy 
limitation of $2.0_million, subject to deductibles, exclusions and 
self-insurance retention amounts. Such coverage, however, may not be adequate 
or available to compensate the Company for all liability that may be imposed. 
The imposition of liability in excess of, or the unavailability of, such 
coverage could have a material adverse effect on the Company's business, 
financial condition and results of operations. 

   The law relating to the regulation and liability of on-line services and 
Internet access providers in relation to information carried or disseminated 
also is undergoing a process of development in other countries. Decisions 
regarding regulation and content liability may significantly affect the 
development and profitability of companies offering on-line and Internet 
access services, including the Company.

RISKS ASSOCIATED WITH FINANCING ARRANGEMENTS

   The Company's financing arrangements are secured by substantially all of 
the Company's assets and stock of certain subsidiaries of the Company and 
require the Company to satisfy certain financial covenants and restrict the 
payment of dividends. As of September 30, 1996, the Company was in compliance 
with these restrictions.  The Company's secured lenders would be entitled to 
foreclose 


                                      25

<PAGE>


upon those assets in the event of a default under the financing arrangements 
and to be repaid from the proceeds of the liquidation of those assets before 
the assets would be available for distribution to the Company's shareholders 
in the event that the Company is liquidated. In addition, the collateral 
security arrangements under the Company's existing financing arrangements may 
adversely affect the Company's ability to obtain additional borrowings.  


GOVERNMENT REGULATORY RISKS

   The 1996 Federal telecommunications legislation imposes criminal liability 
on persons sending or displaying in a manner available to minors indecent 
material on an interactive computer service such as the Internet.  The 1996 
Federal telecommunications legislation also imposes criminal liability on an 
entity knowingly permitting facilities under its control to be used for such 
activities.  Entities solely providing access to facilities not under their 
control (including transmission, downloading, intermediate storage, access 
software and other incidental capabilities) are exempted from liability, as 
are service providers that take good faith, reasonable, effective and 
appropriate actions to restrict access by minors to the prohibited 
communications.  The constitutionality of these provisions is being 
challenged in Federal court, and the interpretation and enforcement of them 
is uncertain.  This legislation may decrease demand for Internet access, 
chill the development of Internet content, or have other adverse effects on 
Internet access providers such as the Company.  In addition, in light of the 
uncertainty attached to interpretation and application of this law, there can 
be no assurance that the Company would not have to modify its operations to 
comply with the statute, including prohibiting users from maintaining home 
pages on the World Wide Web.  

   In January 1995, the U.S. Federal Communications Commission ruled that 
telephone companies must charge a separate Subscriber Line Charge for each 
derived channel available in an ISDN bundle. An ISDN bundle generally 
provides from three to 24 channels. The Company currently does not incur 
increased costs as a result of this ruling due to an effective waiver for 
network access lines.  If however, the waiver were to be revoked, this ruling 
could result in increased costs being imposed on the Company and, 
consequently, could adversely affect the Company's business, results of 
operations and financial condition.

RISK OF SYSTEM FAILURE OR SHUTDOWN

   The success of the Company is dependent upon its ability to deliver 
reliable, high-speed access to the Internet. The Company's network, as is 
also the case with other networks providing similar service, is vulnerable to 
damage or cessation of operations from fire, earthquakes, severe storms, 
power loss, telecommunications failures and similar events, especially if 
such an events occur within a high traffic location of the network.  The 
Company is also dependent upon the ability of its telecommunications 
providers to deliver reliable, high-speed telecommunications service through 
their networks.  While the Company's network has been designed with redundant 
circuits among POPs to allow traffic rerouting, lab and field testing is 
performed before integrating new and emerging technology into the network, 
and the Company engages in capacity planning, there can be no assurance that 
the Company will not experience failures or shutdowns relating to individual 
POPs or even catastrophic failure of the entire network.  The Company carries 
property and business interruption insurance with a basic policy limitation 
of $5.0 million, subject to deductibles, exclusions and self-insurance 
retention amounts. Such coverage, however, may not be adequate to compensate 
the Company for all losses that may occur. In addition, the Company attempts 
to limit its liability to customers arising out of network failures through 
contractual provisions disclaiming all such liability and, in respect of 
certain services, limiting liability to a usage credit based upon the amount 
of time that the system was not operational. There can be no assurance that 
such limitations will be enforceable. In any event, significant or prolonged 
system failures or shutdowns could damage the reputation of the Company and 
result in the loss of subscribers. 

NEW AND UNCERTAIN MARKET

   Substantially all of the Company's revenue to date has been, and for the 
foreseeable future will be, derived from the sale of its Internet access, 
services and products. The Company's success will depend upon the development 
and expansion of the market for Internet access services and products and the 





                                      26

<PAGE>

networks which comprise the Internet. The market for Internet services has 
only recently developed and has been accompanied by increased press coverage 
concerning the scope and nature of the information and services available on, 
and potential uses of, the Internet. Certain critical issues presently 
surrounding commercial use of the Internet, including security, reliability, 
ease and cost of access, and quality of service, remain unresolved and may 
adversely impact the growth of Internet use. If the Internet access market 
fails to grow, grows more slowly than anticipated or becomes saturated with 
competitors, the Company's business, financial condition and results of 
operations would be materially adversely affected. 

SECURITY RISKS; RISKS ASSOCIATED WITH SECURITY OFFERINGS

   Despite the implementation of network security measures by the Company, 
such as limiting physical and network access to its routers, its 
infrastructure is potentially vulnerable to computer viruses, break-ins and 
similar disruptive problems caused by its customers or other Internet users. 
Computer viruses, break-ins or other problems caused by third parties could 
lead to interruptions, delays or cessation in service to the Company's 
customers. Furthermore, such inappropriate use of the Internet by third 
parties could also potentially jeopardize the security of confidential 
information stored in the computer systems of the Company's customers, which 
may deter potential subscribers. Persistent security problems continue to 
plague public and private data networks. Break-ins have reportedly reached 
computers connected to the Internet at General Electric Co., Sprint and IBM 
as well as the computer systems of NETCOM, Netscape and the San Diego 
Supercomputer Center.   Addressing problems caused by computer viruses, 
break-ins or other problems caused by third parties could have a material 
adverse effect on the Company. 

   The security services offered by the Company for use in connection with 
its customers'  networks also cannot assure complete protection from computer 
viruses, break-ins and other disruptive problems.  Although the Company 
attempts to limit  contractually its liability in such instances, the 
occurrence of such problems may result in claims against or liability on the 
part of the Company.  Such claims, regardless of their ultimate outcome, 
could result in costly litigation and could have a material adverse effect on 
the Company's business or reputation or on its ability to attract and retain 
customers for its products.  Moreover, until more consumer reliance is placed 
on security technologies available, the security and privacy concerns of 
existing and potential customers may inhibit the growth of the Internet 
service industry and the Company's customer base and revenues.

DEPENDENCE ON SUPPLIERS

   The Company has few long term-contracts with its suppliers. The Company is 
dependent on third party suppliers for its leased-line connections, or 
bandwidth. Certain of these suppliers are or may become competitors of the 
Company, and such suppliers are not subject to any restrictions upon their 
ability to compete with the Company. To the extent that these suppliers 
change their pricing structures, the Company may be adversely affected. 
Moreover, the Company is dependent on certain third party suppliers of 
hardware components. Although the Company attempts to maintain a minimum of 
two vendors for each required product, certain components used by the Company 
in providing its networking services are currently acquired or available from 
only one source.

   The Company has from time to time experienced delays in the receipt of 
certain hardware components. A failure by a supplier to deliver quality 
products on a timely basis, or the inability to develop alternative sources 
if and as required, could result in delays which could materially adversely 
affect the Company. The Company's remedies against suppliers who fail to 
deliver products on a timely basis are limited by contractual liability 
limitations contained in supply agreements and purchase orders and, in many 
cases, by practical considerations relating to the Company's desire to 
maintain good relationships with the suppliers. As the Company's suppliers 
revise and upgrade their equipment technology, the Company may encounter 
difficulties in integrating the new technology into the Company's network. 

   Certain of the vendors from whom the Company purchases telecommunications 
bandwidth, including the RBOCs and other local exchange carriers ("LECs"), 
currently are subject to tariff controls and other price constraints which in 
the future may be changed. In addition, newly enacted 


                                      27

<PAGE>

legislation will produce changes in the market for telecommunications 
services. These changes may affect the prices charged by the RBOCs and other 
LECs to the Company, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.  Moreover, 
the Company is subject to the effects of other potential regulatory actions 
which, if taken, could increase the cost of the Company's telecommunications 
bandwidth through, for example, the imposition of access charges.

RISKS OF TECHNOLOGY TRENDS AND EVOLVING INDUSTRY STANDARDS

   PSINet's success will depend upon its ability to develop new products and 
provide new services that meet customers' changing requirements. The market 
for Internet access is characterized by rapidly changing technology, evolving 
industry standards, emerging competition, changes in customer needs and 
frequent new service and product introductions. The Company's future success 
will depend, in part, on its ability to effectively use leading technologies, 
to continue to develop its technical expertise, to enhance its current 
services, to develop new services that meet changing customer needs, and to 
influence and respond to emerging industry standards and other technological 
changes on a timely and cost-effective basis. There can be no assurance that 
the Company will be successful in effectively using new technologies, 
developing new services or enhancing its existing services on a timely basis 
or that such new technologies or enhancements will achieve market acceptance. 
The Company believes that its ability to compete successfully is also 
dependent upon the continued compatibility and interoperability of its 
services with products and architectures offered by various vendors. There 
can be no assurance that the Company will be able to effectively address the 
compatibility and interoperability issues raised by technological changes or 
new industry standards.  In addition, there can be no assurance that services 
or technologies developed by others will not render the Company's services or 
technology uncompetitive or obsolete.

DEPENDENCE ON TECHNOLOGY; PROPRIETARY RIGHTS

   The Company's success and ability to compete is dependent in part upon its 
technology and proprietary rights, although the Company believes that its 
success is more dependent upon its technical expertise than its proprietary 
rights. The Company relies on a combination of copyright, trademark and trade 
secret laws and contractual restrictions to establish and protect its 
technology. It may be possible for a third party to copy or otherwise obtain 
and use PSINet's products or technology without authorization or to develop 
similar technology independently, and there can be no assurance that such 
measures are adequate to protect PSINet's proprietary technology. In 
addition, PSINet's products may be licensed or otherwise utilized in foreign 
countries where laws may not protect PSINet's proprietary rights to the same 
extent as do laws in the United States. It is the Company's policy to require 
employees and consultants and, when obtainable, suppliers to execute 
confidentiality agreements upon the commencement of their relationships with 
the Company. These agreements provide that confidential information developed 
or made known during the course of a relationship with the Company is to be 
kept confidential and not disclosed to third parties except in specific 
circumstances. There can be no assurance that the steps taken by the Company 
will be adequate to prevent misappropriation of its technology or that the 
Company's competitors will not independently develop technologies that are 
substantially equivalent or superior to the Company's technology. The Company 
is also subject to the risk of adverse claims and litigation alleging 
infringement of the intellectual property rights of others. From time to time 
the Company has received claims of infringement of other parties' proprietary 
rights. While the Company does not believe that it has infringed the 
proprietary rights of other parties, there can be no assurance that third 
parties will not assert infringement claims in the future with respect to the 
Company's current or future products or that any such claims will not require 
the Company to enter into license arrangements or result in protracted and 
costly litigation, regardless of the merits of such claims. No assurance can 
be given that any necessary licenses will be available or that, if available, 
such licenses can be obtained on commercially reasonable terms.

POTENTIAL VOLATILITY OF STOCK PRICE

   The market price and trading volume of the Company's Common Stock has been 
and may continue to be highly volatile. Factors such as variations in the 
Company's revenue, earnings and cash flow and announcements of new service 
offerings, technological innovations or price reductions by the Company, its 
competitors or providers of alternative services could cause the market price 
of the Common Stock to fluctuate substantially. In addition, the stock 
markets recently have experienced significant price and volume fluctuations 
that particularly have affected technology based companies and resulted in 
changes in the market prices of the stocks of many companies that have not 
been directly related to the operating performance of those companies. Such 
broad market fluctuations have adversely affected and may continue to 
adversely affect the market price of the Common Stock.
