                         NOTES TO FINANCIAL STATEMENTS


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
   ------------------------------------------

   Corporate Subscription Services, Inc. ("CSS" or "the Company"), formerly
   Discount Magazine Subscriptions, Inc., was organized in New Jersey in August
   1991.  The Company provides magazine subscription advice and coordinates
   knowledge acquisition and management services.  The Company's principal
   market is in the United States.

   The Company is subject to risks and uncertainties common to technology-based
   companies including the ability to obtain adequate financing, dependence on
   key individuals, successful development and marketing of its product,
   competition from larger and more established enterprises and the need to
   establish profitable operations. The Company has a negative working capital
   balance and has a net capital deficiency. The Company's continuation as a
   going concern is dependent upon its ability to generate sufficient cash flows
   to meet its obligations on a timely basis or to obtain additional financing
   as may be required. On June 14, 1999, the Company was acquired by RoweCom
   Inc. ("RoweCom") for an aggregate purchase price of approximately $5,900,000.
   Therefore, the Company expects to operate as a subsidiary of RoweCom and
   receive future funding from RoweCom as its parent.

     CASH AND CASH EQUIVALENTS

     Cash and cash equivalents consist of cash and highly liquid investments
     with remaining maturities of three months or less from the date of
     purchase. Carrying amounts approximate fair value due to the short
     maturity of the investments.

     REVENUES

     Revenues are generated from subscription orders for third-party
     publications, which include the cost of the subscription and the associated
     transaction fee earned by CSS. CSS recognizes revenues from a subscription
     order when payment to the supplier is processed.

     RESEARCH AND DEVELOPMENT AND CAPITALIZED SOFTWARE COSTS

     Costs incurred prior to the establishment of technological feasibility
     are charged to research and development expense as incurred.  Software
     production costs incurred subsequent to the establishment of technological
     feasibility are capitalized until the product or enhancement is available
     for general release to customers.  Amortization is based on the straight-
     line method over the remaining estimated life of the product.  Software
     production costs eligible for capitalization have been immaterial.

     ADVERTISING COSTS

     CSS expenses advertising costs as incurred. Advertising expense for the
     year ended December 31, 1998 was $12,309.

     EQUIPMENT AND FURNISHINGS

     Equipment and furnishings are stated at cost, net of accumulated
     depreciation.  Depreciation is provided using the straight-line method over
     the estimated lives of the related assets.  Leasehold improvements are
     depreciated over the shorter of the lease term or the estimated useful
     life.  Upon retirement or sale, the cost of the assets disposed of and the
     related accumulated depreciation are removed from the accounts and any
     resulting gain or loss is included in the determination of net income or
     loss.

                                      -7-

     INCOME TAXES

     The Company has elected to be taxed as an S Corporation for federal and
     certain state income tax purposes and, as a result, is not subject to
     federal taxation. The stockholders are liable for individual federal and
     certain state income taxes on their allocated portions of the Company's
     taxable income.

     CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMER INFORMATION

     Financial instruments, which potentially subject the Company to
     concentrations of credit risk consist primarily of cash and trade
     receivables.  At December 31, 1998, all of the Company's financial
     instruments were held by one financial institution. The Company performs
     ongoing evaluations of customers' financial condition, in certain cases
     requires advances from customers for future purchases and maintains
     reserves for potential uncollectible amounts, which, in the aggregate, have
     not exceeded management expectations. For the year ended December 31, 1998,
     revenues generated from two customers represented 27% of total revenues.

     Two suppliers provided 14% of knowledge resources sold by the Company
     for the year ended December 31, 1998.  If these suppliers were to cease
     providing knowledge resources at favorable prices, the Company may be
     unable to offer competitive prices to its customers.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to provide estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of expense during the
     reporting period.  Actual results could differ from those estimates.

     UNAUDITED INTERIM FINANCIAL DATA

     The interim financial data as of March 31, 1999 and for the three months
     ended March 31, 1999 are unaudited; however, in the opinion of management,
     the interim financial data include all adjustments, consisting only of
     normal recurring adjustments, necessary for a fair presentation of the
     results of operations for these interim periods. The interim financial data
     are not necessarily indicative of the results of operations for a full
     fiscal year.

(b)  UNAUDITED PRO FORMA FINANCIAL STATEMENTS

to certain post-closing adjustments as provided in the agreement), and 16,260
