Archstone Communities Implements Manugistics' Revenue Optimization Software Solution

Manugistics NetWORKS Lease/Rent Optimizer(TM) Helps to Redefine

Pricing in the Apartment Industry; Archstone Expects to See

Revenue Impact Beginning in 2002



Apr 17, 2001, 01:00 ET from Manugistics Group, Inc. and Archstone Communities

    ROCKVILLE, Md., and DENVER, April 17 /PRNewswire/ -- Manugistics Group,
 Inc. (Nasdaq: MANU), the leading global provider of Enterprise Profit
 Optimization(TM) (EPO) solutions, and Archstone Communities (NYSE:   ASN), one
 of the nation's largest developers, owners and operators of apartment
 communities, today announced that Archstone has implemented Manugistics
 NetWORKS Lease/Rent Optimizer(TM) (LRO) -- a revenue optimization solution
 developed for the apartment industry.
     According to R. Scot Sellers, Archstone Chairman and CEO, Archstone
 believes that once the Manugistics solution is fully implemented, it will
 substantially improve the company's pricing and operating capabilities.  "Of
 all our company's innovations, I believe revenue management has the most
 potential to dramatically re-shape our business and our industry," said
 Sellers.  "Moreover, LRO's demand-based pricing gives our product many more
 dimensions, creating a new kind of flexibility that is not currently available
 in the apartment industry.  In this new marketplace, we can accommodate
 customers' move-in dates and lease term needs-rather than force the customer
 conform to our requirements."
     LRO is currently in use at six Archstone communities in Austin, Texas,
 Atlanta and Denver, and the initial results have demonstrated the value of a
 formal revenue management process utilizing LRO.  Archstone expects full
 portfolio implementation by year's end.
     LRO enables apartment operators like Archstone to forecast demand for new
 and renewal leases by unit type at a level of detail virtually impossible to
 compile manually, and to price them to optimize revenue per unit -- striking a
 better balance between yield and occupancy.  The software also takes into
 account customer preferences, market conditions, competitive behavior and
 company-specific capacity and revenue goals.
     "LRO is well-designed to bring a much more intelligent approach to pricing
 in our business.  We are tremendously excited about its future benefits to our
 company -- and our customers," said Daniel A. Amedro, chief information
 officer, Archstone.  "Manugistics' leadership in pricing and revenue
 optimization across multiple industries -- coupled with its solution's history
 of strong, rapid return on investment and demonstrated ease of integration
 into our online leasing system -- made them a strong choice.  The success of
 our initial implementation of the software is compelling evidence that our
 choice was the right one."
     "We see tremendous opportunity for Manugistics NetWORKS Lease/Rent
 Optimizer in the apartment industry," said Greg Cudahy, Manugistics executive
 vice president, Pricing and Revenue Optimization.  "This is a multi-billion
 dollar, highly distributed industry that is experiencing rapid transformation.
 Our solution uses a uniform pricing model to better enable apartment owners
 and managers to enhance profitability."
     Manugistics is an advisory member of the National Multi Housing Council
 (NMHC).  Based in Washington, D.C., NMHC represents the nation's leading firms
 participating in the apartment industry.
